    Full Text Available Obstructive sleep apnea (OSA is characterized by repeated spells of apnea.Collapsibility of hypopharynx due to multiple factors involving pharyngeal dilatormuscles and deposition of fat or fluid in the surrounding soft tissues are importantcontributing factors in its pathogenesis. OSA commonly affects obese individuals.Males are more commonly affected than the females probably due to the disturbingeffect of testosterone on sleep.The impact of OSA on human health include disturbances in endocrine and metabolicsystem affecting hypothalamic-pituitary-gonadal axis, adrenocorticotrophic-cortisolaxis, growth hormone, antidiuretic hormones and insulin resistance. There is atendency for predisposition of the metabolic syndrome or its components includingglycemic dysregulation, hypertension, hyperlipidemia and physical parameters relatedto adiposity. On the other hand, several endocrine disorders such as hypothyroidism,growth hormone excess, polycystic ovarian disease and testosterone replacement areassociated with increased prevalence of OSA.There is limited information on the effect of treatment of OSA by continuous positiveairway pressure (CPAP on the endocrine and metabolic disturbances. There is a needto conduct randomized controlled trials using CPAP therapy in patients with OSA andto study its cause and effect relationship with endocrine and metabolic disturbances.

  7. Can you die from obstructive sleep apnoea syndrome (OSAS)?

    LENUS (Irish Health Repository)

    O'Carroll, G

    2015-02-01

    Studies suggest an independent association between Obstructive Sleep Apnoea Syndrome (OSAS) and cardiovascular death. The purpose of our study is to examine doctors\\' awareness of this association and to determine whether this correlates with recording of OSAS on death certificates. We contacted the Central Statistics Office (CSO) and obtained relevant mention of OSAS on death certificates. We surveyed doctors on their view of OSAS-related deaths, CSO data from 2008-2011 reveal two deaths with OSAS documented as a direct cause and 52 deaths with OSAS as a contributory cause. Seventy-five doctors\\' surveyed (41%) believe OSAS can be a direct cause of death and 177 (96%) believe OSAS can be an indirect cause of death. Only 22 (12%) had putdown OSAS as a cause of death. OSAS is seldom recorded on death certificates. This is at odds with epidemiological forecasts and contrary to an opinion poll from a selection of doctors.

    Full Text Available Continuous positive airways pressure (CPAP is a well known and safe method of treatment patients with obstructive sleep apnoea syndrome (OSAS. The effects of CPAP administration on the upper respiratory tract are known. However its effects on the lower respiratory tract still needs to be determined. Studies on bronchial hyperreactivity in patients treated by CPAP are contradictory. The aim of the study was to assess the influence of a 3-week CPAP treatment in patients with OSAS and to evaluate associations between changes in bronchial reactivity and clinical features of OSAS and lung function tests (LFT. Patients with newly diagnosed OSAS and lack of infection or chronic illness of the respiratory tract or other conditions which could influence bronchial hyperreactivity (BHR were included. Investigations were performed in 101 patients. There were 88 males and 13 females, mean age 51.5±11.2 years and BMI 32.6±5.4 kg·m–2. Qualified patients were randomly divided into 2 groups: 76 patients to CPAP treatment group, 25 control group. Both groups did not differ in anthropometrics features, severity of OSAS and LFT. Metacholine challenge test (MchCT was performed at baseline and repeated after 3 weeks. Analysis of the individual results showed that in 11 patients the MchCT was positive (6 in the CPAP and 5 in the control groups. After 3 weeks in the group of CPAP treated patients an increase of BHR was noted. Log PC20M decreased from 1.38±0.3 to 1.26±0.5 (p<0.05. The number of patients with a positive result in the MchCT increased from 6 to 16 patients. There was no significant change in BHR in the control group. It was found that CPAP treated patients with BHR were older, had less severe OSAS and lower FEV1 (p<0.05. In none of the patients positive result of BHR did no affect compliance to CPAP treatment. Conclusions: CPAP therapy increases bronchial reactivity, but does not affect compliance to treatment.

    Obstructive sleep apnea (OSA) is commonly associated with cognitive dysfunction, which is more apparent in severe OSA and impairs quality of life. However, the clinical screening methods for these impairments in OSA are still limited. In this study, we evaluated the feasibility of using the Memory and Executive Screening (MES) for assessing cognitive performance in OSA. Twenty-four patients with nonsevere OSA and 36 patients with severe OSA participated in this study. All participants underwent comprehensive, laboratory-based polysomnography and completed assessments of cognitive function, which included both the MES and the Beijing version of the Montreal Cognitive Assessment (MoCA-BJ). Both the total MES scores and 5 recall scores of the MES (MES-5R) were significantly lower in the severe OSA group than those in the nonsevere OSA group. The patients with severe OSA performed worse on the memory subtests of the MES-5R, especially on immediate recall. The sensitivity and specificity of the MES for identifying cognitive impairment in patients with OSA were 63.89% and 66.67%, respectively, for a cutoff value of cognitive dysfunction in patients with OSA. The sensitivity and specificity of the MES were similar to those of the MoCA-BJ. The MES-5R and total MES scores can assess the presence and severity of cognitive impairment in patients with severe OSA. Copyright © 2017 Southern Society for Clinical Investigation.

    Objective: To evaluate the impact of obstructive sleep apnea syndrome (OSAS) on human cerebral metabolism by using magnetic resonance spectroscopy (MRS). Materials and methods: Twenty-one severe OSAS patients, 14 mild-moderate OSAS patients, and 15 healthy control subjects were included. All subjects underwent MRS using the point-resolved echo spin spectroscopy (PRESS). Proton volumes of interest were placed in the bilateral frontal lobes and left temporal -parietal-occipital cortex, and left hippocampus. Results: 1. Compared to the controls, the NAA/Cr ratio was significantly decreased in the left frontal lobe in the severe OSAS group (P=0.004), and in the right frontal lobe in the severe (P=0.002) and mild-moderate (P=0.007) OSAS patients. The NAA/Cr ratio trended to be decreased in the left hippocampus in the OSAS patients compared to controls. 2. A significant increase in the ml/Cr ratio was detected in the right frontal regions in the severe (P=0.008) and mild-moderate (P<0.001) OSAS groups. 3. Clx/Cr ratio values were significantly smaller than controls in the left (P=0.006) and right (P=0.027) frontal regions. Conclusion: Bilateral frontal lobes are the vulnerable location in patients with OSAS. MRS can be used to screen the brain metabolic impairment. (authors)

    Overlap syndrome of chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) leads to increased morbidity and mortality. There have been no reports available on the overlap syndrome for Koreans. Our primary aim was to identify prevalence and predictors of the overlap syndrome in Koreans.This is a cross-sectional study with a community-based sample of 1298 participants (mean age, 59.7 ± 6.7) from the cohort of Korean Genomic and Epidemiologic Study during 2013 to 2014. OSA and COPD were assessed by apnea-hypopnea index (AHI) and the ratio of forced expiratory volume in 1 s to forced vital capacity (FEV1/FVC syndrome. The prevalence of COPD remained the same as 10.8% regardless of the presence of OSA. The mean ratio of FEV1/FVC for those with COPD was 0.77, regardless of OSA. The OR increased for age (OR, 1.1; 95% CI, 1.0-1.1) and smokers (OR, 3.6; 95% CI, 2.0-6.4), but decreased for body mass index (BMI) (OR, 0.84; 95% CI, 0.8-0.9) and overweight state (OR, 0.4; 95% CI, 0.2-0.7). Risk factors of the overlap syndrome differed by OSA severity, that is, BMI in those with moderate-to-severe OSA, whereas sex (OR, 4.7; 95% CI, 2.1-10.6) and age (OR, 1.1; 95% CI, 1.0-1.1) in those with mild OSA.In a population study from Korea, 10.8% of OSA patients had an overlap syndrome with COPD. Although BMI is a well-known risk factor of OSA, it is likely that being overweight may be protective for moderate-to-severe OSA patients from the risk of COPD (i.e., overlap syndrome).

    OSA is associated with changes in pharyngeal anatomy. The goal of this study was to objectively and reproducibly quantify pharyngeal anatomy by using digital morphometrics based on a laser ruler and to assess differences between subjects with OSA and control subjects and associations with the apnea-hypopnea index (AHI). To the best of our knowledge, this study is the first to use digital morphometrics to quantify intraoral risk factors for OSA. Digital photographs were obtained by using an intraoral laser ruler and digital camera in 318 control subjects (mean AHI, 4.2 events/hour) and 542 subjects with OSA (mean AHI, 39.2 events/hour). The digital morphometric paradigm was validated and reproducible over time and camera distances. A larger modified Mallampati score and having a nonvisible airway were associated with a higher AHI, both unadjusted (P digital morphometrics is an accurate, high-throughput, and noninvasive technique to identify anatomic OSA risk factors. Morphometrics may also provide a more reproducible and standardized measurement of the Mallampati score. Digital morphometrics represent an efficient and cost-effective method of examining intraoral crowding and tongue size when examining large populations, genetics, or screening for OSA.

    Obstructive sleep-disordered breathing includes a spectrum of clinical entities with variable severity ranging from primary snoring to obstructive sleep apnea syndrome (OSAS). The clinical suspicion for OSAS is most often raised by parental report of specific symptoms and/or abnormalities identified by the physical examination which predispose to upper airway obstruction (e.g., adenotonsillar hypertrophy, obesity, craniofacial abnormalities, neuromuscular disorders). Symptoms and signs of OSAS are classified into those directly related to the intermittent pharyngeal airway obstruction (e.g., parental report of snoring, apneic events) and into morbidity resulting from the upper airway obstruction (e.g., increased daytime sleepiness, hyperactivity, poor school performance, inadequate somatic growth rate or enuresis). History of premature birth and a family history of OSAS as well as obesity and African American ethnicity are associated with increased risk of sleep-disordered breathing in childhood. Polysomnography is the gold standard method for the diagnosis of OSAS but may not be always feasible, especially in low-income countries or non-tertiary hospitals. Nocturnal oximetry and/or sleep questionnaires may be used to identify the child at high risk of OSAS when polysomnography is not an option. Endoscopy and MRI of the upper airway may help to identify the level(s) of upper airway obstruction and to evaluate the dynamic mechanics of the upper airway, especially in children with combined abnormalities.

    Continuous positive airway pressure (CPAP) is currently the most effective treatment method for obstructive sleep apnea syndrome (OSAS). The purpose of this study was to compare the sleep electroencephalogram (EEG) changes before and after the application of CPAP to OSAS patients. A retrospective study was conducted and 45 sequential patients who received both polysomnography (PSG) and CPAP titration were included. The raw data of sleep EEG were extracted and analyzed by engineers using two main factors: fractal dimension (FD) and the zero-crossing rate of detrended FD (zDFD). FD was an effective indicator reflecting the EEG complexity and zDFD was useful to reflect the variability of the EEG complexity. The FD and zDFD indexes of sleep EEG of 45 OSAS patients before and after CPAP titration were analyzed. The age of 45 OSAS patients was 52.7 ± 5.6 years old and the patients include 12 females and 33 males. After CPAP treatment, FD of EEG in non-rapid eye movement (NREM) sleep decreased significantly (P CPAP therapy (P CPAP therapy had a significant influence on sleep EEG in patients with OSAHS, which lead to a more stable EEG pattern. This may be one of the mechanisms that CPAP could improve sleep quality and brain function of OSAS patients.

    This study investigates the effects of exposure to intermittent hypoxia on cardiovascular autonomic control and metabolic function in obese children with obstructive sleep apnea (OSA). Each subject underwent: (1) a polysomnography; (2) morning fasting blood samples and a subsequent FSIVGTT; (3) noninvasive measurement of respiration, arterial blood pressure, and heart rate during supine and standing postures. Assessment of adiposity was performed using a DEXA scan. From these measurements, we deduced the pertinent sleep parameters, Bergman minimal model parameters and the parameters characterizing a minimal model of cardiovascular variability. Results suggest that intermittent hypoxia in OSA contributes independently to insulin resistance and autonomic dysfunction in overweight children.

    Obstructive sleep apnea syndrome (OSA) is a frequent clinical picture. It is characterized by repetitive respiratory arrest with a consecutive decrease in arterial oxygen saturation (SaO 2 ). In clinical practice, the number of desaturations per hour, oxygen desaturation index (ODI), is used as an important diagnostic criterion. Medical literature, however, mentions different threshold values that are defined as pathological. By means of systematic comparative measurements, the study presented here will examine to what extent the diagnosis and the quantification of OSA severity are affected by the device-specific measurement technique, thus impacting the predictive value of nighttime pulse oximetry in outpatient OSA screening. Different pulse oximeters commonly used in clinical practice were analyzed comparatively regarding technical parameters, temporal dynamics and the reproducibility of measuring results. The measurements were executed simultaneously and time synchronized in a reference group of five test subjects (four males, one female, average age 33.0 ± 9.4 years), in a group of five patients (all males, average age 51.8 ± 18.4 years) and using a simulator (pulse oximeter simulator index 2). All devices underestimate the simulator's predetermined oxygen desaturation of 10%. The dispersion of values is high. The device-specific characteristics have a significant influence on the collected data. The fundamental weakness of the systems lies in the reproducibility of measuring results (this only seems adequate at a signal resolution in steps of 0.1%) as well as the differing temporal dynamics. In the synchronous use of different systems on patients for the purpose of a direct comparison of devices, the dispersion of values is serious, reaching a fluctuation range of up to factor 1.42. In measuring dynamic events (apneas), different pulse oximeters do not record identical values. This is due to the different internal signal processing of the devices

    "We have a new strategy to grow our organization." Developing the plan is just the start. Implementing it in the organization is the real challenge. Many organizations don't fail due to lack of strategy; they struggle because it isn't effectively implemented. After working with hundreds of companies on strategy development, Denise and Robert have distilled the critical areas where organizations need to focus in order to enhance profitability through superior execution. If these questions are important to your organization, you'll find useful answers in the following articles: Do you find yourself overwhelmed by too many competing priorities? How do you limit how many strategic initiatives/projects your organization is working on at one time? How do you balance your resource requirements (time and money) with the availability of these resources? How do you balance your strategic initiative requirements with the day-to-day requirements of your organization?

    Hypertrophic tonsillar tissue in children with obstructive sleep apnea (OSA) has enhanced expression of glucocorticoid receptors, which may reflect low endogenous cortisol levels. We have evaluated the effect of the interaction between tonsillar hypertrophy and OSA severity on morning serum cortisol levels. Children with and without snoring underwent polysomnography, tonsillar size grading, and measurement of morning serum cortisol. Seventy children (2-13 years old) were recruited: 30 with moderate-to-severe OSA (apnea-hypopnea index [AHI] > 5 episodes/h), 26 with mild OSA (AHI > 1 and ≤ 5), and 14 controls (no snoring; AHI ≤ 1). Tonsillar hypertrophy was present in 56.7%, 53.8%, and 42.9% of participants in each group, respectively. Application of a general linear model demonstrated a significant effect of the interaction between severity of OSA and tonsillar hypertrophy on cortisol levels (P = 0.04), after adjustment for obesity, gender, and age. Among children with tonsillar hypertrophy, subjects with moderate-to-severe OSA (n = 17; AHI 14.7 ± 10.6), mild OSA (n = 14; AHI 2.3 ± 1.2), and control participants (n = 6; AHI 0.7 ± 0.2) were significantly different regarding cortisol levels (P = 0.02). Subjects with moderate-to-severe OSA had lower cortisol (16.9 ± 8.7 mcg/dL) than those with mild OSA (23.3 ± 4.2; P = 0.01) and those without OSA (controls) (23.6 ± 5.3 mcg/dL; P = 0.04). In contrast, children with normal-size tonsils and moderate-to-severe OSA, mild OSA, and controls did not differ in cortisol levels. Children with moderate-to-severe obstructive sleep apnea and the phenotype of hypertrophic tonsils have reduced morning serum cortisol levels and potentially decreased glucocorticoid inhibitory effects on tonsillar growth.

    To investigate the detection rate and influencing factors of obstructive sleep apnea syndrome (OSAS) in middle-aged and elderly patients with hypertension. A total of 440 patients with hypertension were selected as the research objects, all of them participated in the Berlin questionnaire survey, and the polysomnography (PSG) was performed on the patients with a high risk of OSAS. The detection rate of OSAS was analyzed, the clinical data between non-OSAS group and OSAS group were compared and stepwise linear regression and Logistic regression were used to analyze the related influencing factors to apnea hyponea index (AHI) and OSAS in hypertensive patients. A total of 235 patients completed PSG and 196 patients were diagnosed as OSAS with the detection rate of 83.40%. The detection rate of OSAS in male patients was higher than that in females (89.04% vs.74.16%, x²=8.025, P=0.006). The detection rates of OSAS in normal BMI group, overweight group and obesity group were 56.52%, 92.37% and 100%, respectively (x²=36.438, P<0.001). The detection rates of OSAS in normal waistline group and central obesity group were 74.42% and 88.59% (x²=7.539, P=0.016). The detection rates of OSAS in grade1, grade 2 and grade 3 hypertension groups were 57.47%, 98.23% and 100%, respectively (x²=44.623, P<0.001). BMI, systolic blood pressure (SBP), diastolic blood pressure (DBP), low density lipoprotein (LDL) and waist circumference of OSAS group were all higher than those in non-OSAS group (P<0.05). BMI, SBP and DBP were positively correlated with AHI (p<0.05), which were independent risk factors of OSAS [OR value (95%CI) = 2.548 (1.449-4.327), 1.342 (1.214-1.965) and 1.169 (1.025-1.622), respectively, P<0.05]. The incidence of OSAS in middle-aged and elderly patients with hypertension is high. High BMI, SBP, and DBP are independent risk factors of OSAS.

    The assessment of depression in obstructive sleep apnea (OSA) is confounded by symptom overlap. The Depression, Anxiety, and Stress Scale-short form (DASS-21) is a commonly used measure of negative affect, but it not known whether the DASS-21 is suitable for use in an OSA sample. This study compared the fit of Lovibond and Lovibond's (1995) correlated 3-factor structure of the DASS-21 and measurement invariance between a non-OSA and an OSA sample using confirmatory factor analysis. As measurement invariance was not found, to determine the source of non-invariance differential item functioning (DIF) was examined using dMACS. The correlated 3-factor structure (with correlated errors) of the DASS-21 was a better fit in the non-OSA sample. dMACS indicated that there was a degree of DIF for each of the subscales, especially for the Anxiety subscale, in which 2 symptoms (that are also physiological symptoms of OSA) produced lower severity scores in the OSA sample compared with the non-OSA sample. However, the degree of DIF for each of the subscales is not sufficient to cause concern when using the DASS-21; therefore, the total DASS-21 is suitable for use in an OSA sample. Interestingly, the impact of symptom overlap in anxiety symptoms may be reducing anxiety scores because of DIF, which contrasts with the proposed effect of symptom overlap in depression, where it leads to the inflation of depression scores in OSA. This deserves greater consideration in relation to OSA and other clinical disorders or chronic illness conditions with different patterns of overlapping symptoms.

    Starch from sago (Metroxylon sagu) was esterified with octenyl succinic anhydride (OSA) in order to regulate its shortcoming by adding amphiphilic properties. The objective of this work is to determine the physicochemical properties of native sago and OSA sago starches. The OSA sago starch was produced according to the optimum condition generated via response surface methodology (RSM) with 5.00 % OSA at pH 7.20 and a reaction time of 9.65 hours. The esterified sago starch gives a degree of substitution (DS) value of 0.012. The physicochemical properties of OSA sago starch was determined by measuring the amylose content, laser diffraction particle size analyzer, scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR). The amylose content for OSA sago starch was found to be reduced after esterification reaction. The particle size of OSA sago starch was found to increase significantly (p<0.05) compared to their native starches. Scanning electron microscopy (SEM) revealed that OSA starch developed slightly rough surface and their edges lost some definition. FT-IR spectroscopy shows that there was appearance of new absorption correspond to ester carbonyl group (1717 cm -1 ) and carboxylate RCOO- (1569 cm -1 ). This study showed that the physicochemical properties of modified starches were influenced not only by DS but also on the botanical origin of the starches. (author)

  14. Executive Dysfunction

    2015-01-01

    Purpose of Review: Executive functions represent a constellation of cognitive abilities that drive goal-oriented behavior and are critical to the ability to adapt to an ever-changing world. This article provides a clinically oriented approach to classifying, localizing, diagnosing, and treating disorders of executive function, which are pervasive in clinical practice. Recent Findings: Executive functions can be split into four distinct components: working memory, inhibition, set shifting, and fluency. These components may be differentially affected in individual patients and act together to guide higher-order cognitive constructs such as planning and organization. Specific bedside and neuropsychological tests can be applied to evaluate components of executive function. While dysexecutive syndromes were first described in patients with frontal lesions, intact executive functioning relies on distributed neural networks that include not only the prefrontal cortex, but also the parietal cortex, basal ganglia, thalamus, and cerebellum. Executive dysfunction arises from injury to any of these regions, their white matter connections, or neurotransmitter systems. Dysexecutive symptoms therefore occur in most neurodegenerative diseases and in many other neurologic, psychiatric, and systemic illnesses. Management approaches are patient specific and should focus on treatment of the underlying cause in parallel with maximizing patient function and safety via occupational therapy and rehabilitation. Summary: Executive dysfunction is extremely common in patients with neurologic disorders. Diagnosis and treatment hinge on familiarity with the clinical components and neuroanatomic correlates of these complex, high-order cognitive processes. PMID:26039846

  15. Comparative Emulsifying Properties of Octenyl Succinic Anhydride (OSA-Modified Starch: Granular Form vs Dissolved State.

    Directory of Open Access Journals (Sweden)

    María Matos

    Full Text Available The emulsifying ability of OSA-modified and native starch in the granular form, in the dissolved state and a combination of both was compared. This study aims to understand mixed systems of particles and dissolved starch with respect to what species dominates at droplet interfaces and how stability is affected by addition of one of the species to already formed emulsions. It was possible to create emulsions with OSA-modified starch isolated from Quinoa as sole emulsifier. Similar droplet sizes were obtained with emulsions prepared at 7% (w/w oil content using OSA-modified starch in the granular form or molecularly dissolved but large differences were observed regarding stability. Pickering emulsions kept their droplet size constant after one month while emulsions formulated with OSA-modified starch dissolved exhibited coalescence. All emulsions stabilized combining OSA-modified starch in granular form and in solution showed larger mean droplet sizes with no significant differences with respect to the order of addition. These emulsions were unstable due to coalescence regarding presence of free oil. Similar results were obtained when emulsions were prepared by combining OSA-modified granules with native starch in solution. The degree of surface coverage of starch granules was much lower in presence of starch in solution which indicates that OSA-starch is more surface active in the dissolved state than in granular form, although it led to unstable systems compared to starch granule stabilized Pickering emulsions, which demonstrated to be extremely stable.

    Full Text Available Obstructive sleep apnea syndrome (OSAS is a common clinical condition. The way that OSAS risk factors associate and converge is not a random process. As such, defining OSAS phenotypes fosters personalized patient management and population screening. In this paper, we present a network-based observational, retrospective study on a cohort of 1,371 consecutive OSAS patients and 611 non-OSAS control patients in order to explore the risk factor associations and their correlation with OSAS comorbidities. To this end, we construct the Apnea Patients Network (APN using patient compatibility relationships according to six objective parameters: age, gender, body mass index (BMI, blood pressure (BP, neck circumference (NC and the Epworth sleepiness score (ESS. By running targeted network clustering algorithms, we identify eight patient phenotypes and corroborate them with the co-morbidity types. Also, by employing machine learning on the uncovered phenotypes, we derive a classification tree and introduce a computational framework which render the Sleep Apnea Syndrome Score (SASScore; our OSAS score is implemented as an easy-to-use, web-based computer program which requires less than one minute for processing one individual. Our evaluation, performed on a distinct validation database with 231 consecutive patients, reveals that OSAS prediction with SASScore has a significant specificity improvement (an increase of 234% for only 8.2% sensitivity decrease in comparison with the state-of-the-art score STOP-BANG. The fact that SASScore has bigger specificity makes it appropriate for OSAS screening and risk prediction in big, general populations.

    Unintentional leakage from the mouth or around the mask may lead to cessation of CPAP treatment; however, the causes of unintentional leaks are poorly understood. The objectives of this study were (1) to identify determining factors of unintentional leakage and (2) to determine the effect of the type of mask (nasal/oronasal) used on unintentional leakage. Seventy-four polysomnograms from patients with OSA syndrome treated with auto-CPAP were analyzed (23 women; 56 ± 13 years; BMI, 32.9 kg/m 2 (range, 29.0-38.0 kg/m 2 ). Polysomnographic recordings were obtained under auto-CPAP, and mandibular behavior was measured with a magnetic sensor. After sleep and respiratory scoring, polysomnographic signals were computed as mean values over nonoverlapping 10-s intervals. The presence/absence of unintentional leakage was dichotomized for each 10-s interval (yes/no). Univariate and multivariate conditional regression models estimated the risk of unintentional leaks during an interval "T" based on the explanatory variables from the previous interval "T-1." A sensitivity analysis for the type of mask was then conducted. The univariate analysis showed that mandibular lowering (mouth opening), a high level of CPAP, body position (other than supine), and rapid eye movement (REM) sleep increased the risk of unintentional leaks and microarousal decreased it. In the multivariate analysis, the same variables remained independently associated with an increased risk of unintentional leakage. The sensitivity analysis showed that oronasal masks reduced the risk of unintentional leaks in cases of mouth opening and REM sleep. Mouth opening, CPAP level, sleep position, and REM sleep independently contribute to unintentional leakage. These results provide a strong rationale for the definition of phenotypes and the individual management of leaks during CPAP treatment. Copyright © 2017 American College of Chest Physicians.

We aimed to characterize the older asthma phenotype and test its association with obstructive sleep apnea (OSA. Design. Cross-sectional. Setting. Pulmonary and Asthma/Allergy clinics. Participants. 659 asthma subjects aged 18–59 years (younger and 154 aged 60–75 (older. Measurements. Sleep Apnea scale of Sleep Disorders Questionnaire (SA-SDQ, asthma severity step (1–4, severe if step 3 or 4, established OSA diagnosis, continuous positive airway pressure (CPAP use, and comorbidities. Results. Older versus younger had worse control, as assessed by asthma step, lung function, and inhaled corticosteroid use. Among older subjects, after controlling for known asthma aggravators, OSA diagnosis was the only factor robustly associated with severe asthma: on average, OSA was associated with nearly 7 times greater likelihood of severe asthma in an older individual (OR=6.67. This relationship was of greater magnitude than in younger subjects (OR=2.16. CPAP use attenuated the likelihood of severe asthma in older subjects by 91% (P=0.005, much more than in the younger asthmatics. Conclusion. Diagnosed OSA increases the risk for worse asthma control in older patients, while CPAP therapy may have greater impact on asthma outcomes. Unrecognized OSA may be a reason for poor asthma control, particularly among older patients.

    Obstructive Sleep Apnoea (OSA) is a highly prevalent disease and a major public health issue in India. Excessive daytime sleepiness is an almost ubiquitous symptom of OSA. Epworth Sleepiness Scale (ESS) score is a validated objective score to measure the degree of daytime sleepiness. Continuous Positive Airway Pressure (CPAP) therapy has been established as the gold standard treatment modality for OSA patients. A few Indian studies have reported the effectiveness of CPAP therapy in improving ESS scores after 1 st month of CPAP use. To observe both, short-term (one month) and long-term (three month) effects of CPAP therapy on ESS scores in moderate to severe OSA patients. The patients complaining of excessive day-time sleepiness, snoring and choking episodes during sleep, consecutively presenting to medicine OPD over a period of 2 years, were subjected to Polysomnography (PSG). Seventy-three patients with apnoea-hypopnea index (AHI) ≥15 were categorised as having moderate to severe forms of OSA (moderate OSA with AHI=15-30 and severe OSA with AHI >30), and were scheduled for an initial trial of CPAP therapy. Forty-seven patients reported good tolerance to CPAP therapy after a trial period of 2 weeks and comprised the final study group. ESS scores in these patients were recorded at the baseline, and after 1 st and 3 rd month of CPAP therapy, and statistically analysed for significance. Mean ESS score at the baseline among moderate and severe OSA patients were 13.67±2.29 and 16.56 ±1.87, respectively. ESS score in both these subgroups improved significantly to 11.63±3.79, p=0.022, CI (0.3293-4.0106)} and 14.13 ±3.74, p CPAP therapy. Likewise, mean ESS scores among moderate and severe OSA patients improved significantly to 9.84 ±2.97, p = 0.022, CI (0.3293-4.0106) and 12.29 ±3.97, p CPAP therapy. The result of the present study shows that CPAP therapy is significantly effective in improving ESS scores in Indian patients having moderate to severe OSA. Benefits

    Improvement is sought for youth with obstructive sleep apnea syndrome (OSAS) who have poor quality of life (QoL), which resolves somewhat following treatment. One mitigating factor in improved QoL following treatment may be adherence to the CPAP protocol, which presents a barrier to most youth. This study explored relations between CPAP adherence and QoL in youth with OSAS. We recruited 42 youth-caregiver dyads in which youth between the ages of 8 and 16 years were diagnosed with OSAS and required CPAP use as part of their treatment plan. Following diagnosis of OSAS requiring treatment with CPAP therapy, caregivers completed baseline measures of OSAS-specific QoL. The OSAS-specific QoL domains assessed included sleep disturbance, physical symptoms, emotional distress, daytime function, and caregiver concern. Families received routine CPAP care for three months, after which caregivers again completed measures of OSAS-specific QoL. Adherence data were collected from smartcards within the CPAP machine after three months of treatment. Fifteen youth were adherent to CPAP therapy and 10 were not adherent. CPAP-adherent youth demonstrated significant changes in two domains of OSAS-specific QoL when compared to nonadherent youth: decreased sleep disturbance and decreased caregiver concern. CPAP adherence appears to be associated with positive changes in OSAS-specific QoL domains. It will be important for future research and clinical work to examine strategies for improving CPAP adherence in youth with OSAS.

    Both allergic rhinitis (AR) and obstructive sleep apnea (OSA) are known to increase stress and fatigue, but the result of their coexistence has not been studied. The objective of this study was to evaluate the amount of stress and fatigue when AR is combined with OSA. One hundred and twelve patients diagnosed with OSA by polysomnography were enrolled. Among them, 37 patients were diagnosed with AR by a skin prick test and symptoms (OSA-AR group) and 75 patients were classified into the OSA group since they tested negative for allergies. We evaluated the Epworth sleepiness scale (ESS), stress score, fatigue score, ability to cope with stress, and rhinosinusitis quality of life questionnaire (RQLQ) with questionnaires and statistically compared the scores of both groups. There were no significant differences in BMI and sleep parameters such as LSAT, AHI, and RERA between the two groups. However, the OSA-AR group showed a significantly higher ESS score compared to the OSA group (13.7 ± 4.7 vs. 9.3 ± 4.8). Fatigue scores were also significantly higher in the OSA-AR group than in the OSA group (39.8 ± 11.0 vs. 30.6 ± 5.4). The OSA-AR group had a significantly higher stress score (60.4 ± 18.6 vs. 51.2 ± 10.4). The ability to cope with stress was higher in the OSA group, although this difference was not statistically significant. RQLQ scores were higher in the OSA-AR group (60.2 ± 16.7 compared to 25.1 ± 13.9). In conclusion, management of allergic rhinitis is very important in treating OSA patients in order to eliminate stress and fatigue and to minimize daytime sleepiness and quality of life.

    Obstructive sleep apnea (OSA) is known to be a risk factor of coronary artery disease. Monocyte chemoattractant protein-1 (MCP-1), as a critical factor for monocyte infiltration, is known to play a role in the development of atherosclerosis. This study aimed to investigate the effect of intermittent hypoxia, the hallmark of OSA, on the MCP-1 expression of monocytes. Peripheral blood was sampled from 61 adults enrolled for suspected OSA. RNA was prepared from the isolated monocytes for the analysis of MCP-1. The effect of in vitro intermittent hypoxia on the regulation and function of MCP-1 was investigated on THP-1 monocytic cells and human monocytes. The mRNA and secreted protein levels were investigated by RT/real-time PCR and enzyme-linked immunosorbent assay, respectively. Monocytic MCP-1 gene expression was found to be increased significantly in severe OSA patients. In vitro intermittent hypoxia was demonstrated to increase the mRNA and protein expression levels of MCP-1 dose- and time-dependently in THP-1 monocytic cells. The MCP-1 mRNA expression in monocytes isolated from OSA patient was induced to a much higher level compared to that from normal control. Pre-treatment with inhibitor for p42/44 MAPK or p38 MAPK suppressed the activation of MCP-1 expression by intermittent hypoxia. This is the first study to demonstrate the increase of MCP-1 gene expression in monocytes of severe OSA patients. In addition, monocytic MCP-1 gene expression can be induced under intermittent hypoxia.

    Obstructive sleep apnea (OSA) is reported in 70% of adolescents who present for bariatric surgery. The Pediatric Sleep Questionnaire (PSQ) was developed to identify children at risk for OSA but is not validated in adolescents with obesity. The aims of this study were: (1) to assess validity of the PSQ to detect OSA and (2) to determine the correlation between anthropometric and polysomnography measurements. A cross-sectional assessment of Teen-Longitudinal Assessment of Bariatric Surgery participants at high risk for OSA was performed. Participants completed an overnight polysomnography, and caregivers completed the PSQ. Forty-five participants (84% female, 78% Caucasian, mean age = 16.7 ± 1.5 years) were evaluated. Mean BMI was 51.3 ± 7.7 kg/m 2 and mean obstructive apnea-hypopnea index (oAHI) was 6.1 ± 5.9 events/h. For diagnosis of OSA (oAHI ≥5), the total PSQ score sensitivity, specificity, and positive predictive value (PPV) were 86%, 38%, and 55%, respectively. For snoring >50% of the time, PPV was 84%, sensitivity was 64%, and specificity was 43%. Sagittal abdominal diameter correlated with oAHI and oxygen saturation nadir (ρ = 0.34, P = 0.027), whereas BMI, neck, and waist circumference correlated with neither. The PSQ demonstrated low specificity, and PPV and the question regarding snoring >50% of the time did not effectively identify OSA. Sagittal abdominal diameter correlated with oAHI and oxygen saturation nadir. © 2016 The Obesity Society.

  12. Executive summary

    International Nuclear Information System (INIS)

    2002-01-01

    On 18 May 2001, the Finnish Parliament ratified the Decision in Principle on the final disposal facility for spent nuclear fuel at Olkiluoto, within the municipality of Eurajoki. The Municipality Council and the government has made positive decisions earlier, at the end of 2000, and in compliance with the Nuclear Energy Act, Parliament's ratification was then required. The decision is valid for the spent fuel generated by the existing Finnish nuclear power plants and means that the construction of the final disposal facility is considered to be in line with the overall good of society. Earlier steps included, amongst others, the approval of the technical project by the Safety Authority. Future steps include construction of an underground rock characterisation facility, ONKALO (2003-2004), and application for separate construction and operating licences for the final disposal facility (from about 2010). How did this political and societal decision come about? The FSC Workshop provided the opportunity to present the history leading up to the Decision in Principle (DiP), and to examine future perspectives with an emphasis on stakeholder involvement. This Executive Summary gives an overview of the presentations and discussions that took place at the workshop. It presents, for the most part, a factual account of the individual presentations and of the discussions that took place. It relies importantly on the notes that were taken at the meeting. Most materials are elaborated upon in a fuller way in the texts that the various speakers and session moderators contributed for these proceedings. The structure of the Executive Summary follows the structure of the workshop itself. Complementary to this Summary and also provided with this document, is a NEA Secretariat's perspective aiming to place the results of all discussions, feedback and site visit into an international perspective.

    2014-03-01

    Independently, obstructive sleep apnea (OSA) and infectious mononucleosis are not uncommon in the pediatric population, but acute onset of OSA, as a respiratory complication in the setting of acute EBV infection is extremely uncommon. Previous reports of this clinical entity are sparse and from nearly two decades ago. Urgent adenotonsillectomy was commonly advocated. This complication may be managed medically with systemic corticosteroids and non-invasive continuous positive airway pressure (CPAP), and a case is presented to highlight an updated management approach to this rarely encountered clinical problem in children.

    Full Text Available The combination of chronic obstructive pulmonary disease (COPD and obstructive sleep apnea (OSA is associated with substantial morbidity and mortality. We hypothesized that predictors of OSA among patients with COPD may be distinct from OSA in the general population. Therefore, we investigated associations between traditional OSA risk factors (e.g. age, and sleep questionnaires [e.g. Epworth Sleepiness Scale] in 44 patients with advanced COPD. As a second aim we proposed a pilot, simplified screening test for OSA in patients with COPD. In a prospective, observational study of patients enrolled in the UCSD Pulmonary Rehabilitation Program we collected baseline characteristics, cardiovascular events (e.g. atrial fibrillation, and sleep questionnaires [e.g. Pittsburgh Sleep Quality Index (PSQI]. For the pilot questionnaire, a BMI ≥25 kg/m2 and the presence of cardiovascular disease were used to construct the pilot screening test. Male: 59%; OSA 66%. FEV1 (mean ± SD = 41.0±18.2% pred., FEV1/FVC = 41.5±12.7%]. Male gender, older age, and large neck circumference were not associated with OSA. Also, Epworth Sleepiness Scale and the STOP-Bang questionnaire were not associated with OSA in univariate logistic regression. In contrast, BMI ≥25 kg/m2 (OR = 3.94, p = 0.04 and diagnosis of cardiovascular disease (OR = 5.06, p = 0.03 were significantly associated with OSA [area under curve (AUC = 0.74].

The COPD-OSA test had the best AUC (0.74, sensitivity (92%, and specificity (83%. A ten-fold cross-validation validated our results. We found that traditional OSA predictors (e.g. gender, Epworth score did not perform well in patients with more advanced COPD. Our pilot test may be an easy to implement instrument to screen for OSA. However, a larger validation study is necessary

    Optical sensors based on absorption spectroscopy play a central role in the detection and monitoring of atmospheric trace gases. We here present for the first time the experimental demonstration of OSAS-Lidar on the remote sensing of CH4 in the atmosphere. This new methodology, the OSAS-Lidar, couples the Optical Similitude Absorption Spectroscopy (OSAS) methodology with a light detection and ranging device. It is based on the differential absorption of spectrally integrated signals following Beer Lambert-Bouguer law, which are range-resolved. Its novelty originates from the use of broadband laser spectroscopy and from the mathematical approach used to retrieve the trace gas concentration. We previously applied the OSAS methodology in laboratory on the 2ν3 methane absorption band, centered at the 1665 nm wavelength and demonstrated that the OSAS-methodology is almost independent from atmospheric temperature and pressure. In this paper, we achieve an OSAS-Lidar device capable of observing large concentrations of CH4 released from a methane source directly into the atmosphere. Comparison with a standard in-situ measurement device shows that the path-integrated concentrations retrieved from OSAS-Lidar methodology exhibit sufficient sensitivity (2 000 ppm m) and observational time resolution (1 s) to remotely sense methane leaks in the atmosphere. The coupling of OSAS-lidar with a wind measurement device opens the way to monitor time-resolved methane flux emissions, which is important in regards to future climate mitigation involving regional reduction of CH4 flux emissions.

  19. Lack of effect of sleep apnea on oxidative stress in obstructive sleep apnea syndrome (OSAS patients.

    M Simiakakis

    Full Text Available PURPOSE: The aim of this study was to evaluate markers of systemic oxidative stress and antioxidant capacity in subjects with and without OSAS in order to investigate the most important factors that determine the oxidant-antioxidant status. METHODS: A total of 66 subjects referred to our Sleep laboratory were examined by full polysomnography. Oxidative stress and antioxidant activity were assessed by measurement of the derivatives of reactive oxygen metabolites (d-ROMs and the biological antioxidant capacity (BAP in blood samples taken in the morning after the sleep study. Known risk factors for oxidative stress, such as age, sex, obesity, smoking, hypelipidemia, and hypertension, were investigated as possible confounding factors. RESULTS: 42 patients with OSAS (Apnea-Hypopnea index >15 events/hour were compared with 24 controls (AHI<5. The levels of d-ROMS were significantly higher (p = 0.005 in the control group but the levels of antioxidant capacity were significantly lower (p = 0.004 in OSAS patients. The most important factors predicting the variance of oxidative stress were obesity, smoking habit, and sex. Parameters of sleep apnea severity were not associated with oxidative stress. Minimal oxygen desaturation and smoking habit were the most important predicting factors of BAP levels. CONCLUSION: Obesity, smoking, and sex are the most important determinants of oxidative stress in OSAS subjects. Sleep apnea might enhance oxidative stress by the reduction of antioxidant capacity of blood due to nocturnal hypoxia.

    Full Text Available Introduction. This study aims to investigate the reasons that discourage the patients affected by OSAS to undergo orthognathic surgery and compares the postoperative discomfort of phase I (soft tissue surgery and phase II (orthognathic surgery procedures for treatment of OSAS. Material and Methods. A pool of 46 patients affected by OSAS was divided into two groups: “surgery patients” who accepted surgical treatments of their condition and “no surgery patients” who refused surgical procedures. The “surgery patients” group was further subdivided into two arms: patients who accepted phase I procedures (IP and those who accepted phase II (IIP. To better understand the motivations behind the refusal of II phase procedures, we asked the patients belonging to both the IP group and “no surgery” group to indicate the main reason that influenced their decision to avoid II phase procedures. We also monitored and compared five parameters of postoperative discomfort: pain, painkiller assumption, length of hospitalization, foreign body sensation, and diet assumption following IP and IIP procedures. Results. The main reason to avoid IIP procedures was the concern of a more severe postoperative discomfort. Comparison of the postoperative discomfort following IP versus IIP procedures showed that the former scored worse in 4 out of 5 parameters analyzed. Conclusion. IIP procedures produce less postoperative discomfort. IIP procedures, namely, orthognathic surgery, should be the first choice intervention in patients affected by OSAS and dentoskeletal malformation.

    Nocturnal gastro-oesophageal reflux (nGOR) is associated with asthma and obstructive sleep apnoea (OSA). Our aim was to investigate whether nGOR is a risk factor for onset of asthma and onset of respiratory and OSA symptoms in a prospective population-based study. We invited 2640 subjects from Iceland, Sweden and Belgium for two evaluations over a 9-year interval. They participated in structured interviews, answered questionnaires, and underwent spirometries and methacholine challenge testing. nGOR was defined by reported symptoms. Subjects with persistent nGOR (n=123) had an independent increased risk of new asthma at follow-up (OR 2.3, 95% CI 1.1-4.9). Persistent nGOR was independently related to onset of respiratory symptoms (OR 3.0, 95% CI 1.6-5.6). The risk of developing symptoms of OSA was increased in subjects with new and persistent nGOR (OR 2.2, 95% CI 1.3-1.6, and OR 2.0, 95% CI 1.0-3.7, respectively). No significant association was found between nGOR and lung function or bronchial responsiveness. Persistent symptoms of nGOR contribute to the development of asthma and respiratory symptoms. New onset of OSA symptoms is higher among subjects with symptoms of nGOR. These findings provide evidence that nGOR may play a role in the genesis of respiratory symptoms and diseases.

    Full Text Available Egg yolk was partially replaced (0, 25, 50, 75, and 100% with octenyl succinic anhydride (OSA-modified potato starch in a reduced-fat mayonnaise formulation to curtail the problems associated with high cholesterol and induced allergic reactions. The physicochemical properties included parameters such as: pH, fat content, and emulsion stability of the formulations analyzed. The samples with 75% and 100% egg yolk substitute showed the maximum emulsion stability (>95% after two of months storage, and they were selected according to cholesterol content, particle size distributions, dynamic rheological properties, microstructure, and sensory characteristic. A significant reduction (84-97% in the cholesterol content was observed in the selected samples. Particle size analysis showed that by increasing the amount of OSA starch, the oil droplets with the peak size of 70 µm engulfed by this compound became larger. The rheological tests elucidated that in the absence of egg yolk, OSA starch may not result in a final product with consistent texture and that the best ratio of the two emulsifiers (OSA starch/egg yolk to produce stable reduced-fat, low cholesterol mayonnaise is 75/25. The microscopic images confirmed the formation of a stable cohesive layer of starch surrounding the oil droplets emulsified in the samples selected.

    Nasal CPAP is the "gold standard" treatment for OSA. However, oronasal masks are frequently used in clinical practice. The aim of this study was to perform a meta-analysis of all randomized and nonrandomized trials that compared nasal vs oronasal masks on CPAP level, residual apnea-hypopnea index (AHI), and CPAP adherence to treat OSA. The Cochrane Central Register of Controlled Trials, Medline, and Web of Science were searched for relevant studies in any language with the following terms: "sleep apnea" and "CPAP" or "sleep apnea" and "oronasal mask" or "OSA" and "oronasal CPAP" or "oronasal mask" and "adherence." Studies on CPAP treatment for OSA were included, based on the following criteria: (1) original article; (2) randomized or nonrandomized trials; and (3) comparison between nasal and oronasal CPAP including pressure level, and/or residual AHI, and/or CPAP adherence. We identified five randomized and eight nonrandomized trials (4,563 patients) that reported CPAP level and/or residual AHI and/or CPAP adherence. Overall, the random-effects meta-analysis revealed that as compared with nasal, oronasal masks were associated with a significantly higher CPAP level (Hedges' g, -0.59; 95% CI, -0.82 to -0.37; P CPAP level, higher residual AHI, and poorer adherence than nasal masks.

    Patients with obstructive sleep apnoea syndrome (OSAS) have an increased car accident rate. Investigations on accident frequency are based on case history, insurance reports and driving simulator studies. The present study combines neuropsychological testing of different attention aspects engaged in driving a car and driving simulation to evaluate a suitable instrument for assessing therapeutic effects of continuous positive airway pressure (CPAP). Driving simulator investigation and neuropsychological testing of alertness, vigilance and divided attention were performed in 31 patients with polysomnographically confirmed OSAS (apnoea-hypopnoea index 24.8+/-21.5.h(-1)) before, and 2 and 42 days after initiation of CPAP. Divided attention and alertness improved significantly during CPAP, whereas vigilance remained unchanged. However, accident frequency (OSAS before therapy: 2.7+/-2.0; 2 days after CPAP: 1.5+/-1.4; 42 days after CPAP: 0.9+/-1.3) and frequency of concentration faults (OSAS before therapy: 12.4+/-5.1; 2 days after CPAP: 6.5+/-3.9; 42 days after CPAP: 4.9+/-3.3) decreased in the simulated driving situation after 2 and 42 days of therapy. There was no relation between accident frequency, concentration faults and daytime sleepiness, as measured by the Epworth Sleepiness Scale, and polysomnographic or neuropsychological findings, respectively. In conclusion, the present results suggest that driving simulation is a possible benchmark parameter of driving performance in obstructive sleep apnoea syndrome patients.

    The USC-OSA Student Chapter has been constituted in March 2013 by members of the University of Santiago de Compostela (USC) in Spain and sponsored by The Optical Society of America (OSA). It is formed by five graduate and one undergraduate students with the common interest in Optics and Photonics research and a professor of the USC is also involved as a faculty advisor. We decided to start this group with the aim of involving kids, precollege and undergraduate students in the world of Optics and Photonics. The activities that the USC-OSA Student Chapter members intend to realize are mainly educational tasks for the spreading of knowledge in Photonics by means of basic experiments, demonstrations and lectures by leading researchers and teachers. Most of the needed resources to accomplish these activities are provided by the OSA, such as educational posters and a portable kit for demonstrating Optics to students. At this moment the USC-OSA Student Chapter is carrying out several activities, as educational journeys at the Santiago de Compostela University Hospital Complex (CHUS), where hospitalized children can approach to Optics through some simple experiments and games. A teaching program is also being organized in collaboration with Galician secondary schools in order to show students the importance and uses of Optics and Photonics and to arouse their interest in this field, as well as encouraging them to develop their scientific thinking. Another activity will take place in November during the Science Week, which includes a program of lectures targeted to undergraduate students and an exposition of several demonstrations

    Obstructive sleep apnea (OSA) leads to upper respiratory tract obstruction, causing increased abdominal-gastric pressure and decreased lower esophageal sphincter (LES) pressure and thus gastroesophageal reflux (GER). Continuous positive airway pressure (CPAP) is known to be an effective method for OSA treatment, but its effect on GER is still controversial. There are a very few studies investigating CPAP and GER relationship and performed based on pre- and post-treatment objective parameters of GER in patients with OSA. The study investigated the effect of CPAP treatment in patients with moderate and severe OSA without GER complaints on pre- and post-treatment objective GER parameters. The study included 25 patients with respiratory disturbance indices >15 without reflux symptoms who had undergone polysomnography at sleep laboratory. Age, sex, body mass index (BMI), waist, and neck circumference of the patients were documented. DeMeester score, LES pressure, and polysomnography parameters were evaluated pre- and post-CPAP. The results were statistically evaluated, and p value CPAP phase, mean sphincter pressure was 22.2 ± 1.2 (range 8-73), and mean DeMeester score was 18 ± 15.5 (range 0.2-57). At the post-CPAP, mean sphincter pressure was 22.9 ± 1.6 (range 9-95), and mean DeMeester score was 16.3 ± 14.8 (range 0.2-55). No significant difference (p > 0.05) was found comparing pre-CPAP and post-CPAP measurements. Objective criteria show that CPAP treatment does not cause reflux in patients with OSA. Unlike studies reported in the literature, this conclusion has been reached by pre- and post-CPAP assessments.

    Although continuous positive airway pressure (CPAP) is the most effective treatment modality, poor adherence still remains a problem for obstructive sleep apnea (OSA) treatment and there is little evidence regarding how this might be improved. This study aims to analyze the anatomic and clinical factors of OSA subjects who failed to comply with CPAP therapy.The medical records of 47 OSA subjects who received CPAP therapy as a first-line treatment modality were retrospectively reviewed. The medical records were reviewed for demographic and polysomnographic data and anatomic findings of the nasal cavity and oropharynx.24 patients who adhered to CPAP therapy and 23 patients who were nonadherent were enrolled in the study. There were no statistically significant differences in sleep parameters between CPAP-adherent patients and CPAP nonadherent subjects. Mean body mass index of CPAP nonadherent group was significantly higher than CPAP adherent group. Higher grades of septal deviation and hypertrophic change of the inferior turbinate were observed more in the CPAP nonadherent group. In addition, CPAP nonadherent subjects showed considerably bigger tonsils and higher grade palatal position comparing with the CPAP adherent subjects. Subjective discomfort including inconvenience, mouth dryness, and chest discomfort were the main problems for OSA subjects who did not comply with CPAP therapy.Excessive upper airway blockage in the nasal cavity and oropharynx was predominant in CPAP nonadherent subjects, which might cause the reported subjective discomfort that reduces CPAP compliance. Therefore, resolution of these issues is needed to enhance CPAP compliance for control of OSA. Copyright © 2017 The Authors. Published by Wolters Kluwer Health, Inc. All rights reserved.

    Based on meta-analyses, the BP-lowering effect of CPAP therapy in patients with OSA is reported to be approximately 2 to 3 mm Hg. This figure is derived from heterogeneous trials, which are often limited by poor CPAP adherence, and thus the treatment effect may possibly be underestimated. We analyzed morning BP data from three randomized controlled CPAP withdrawal trials, which included only patients with optimal CPAP compliance. Within the three trials, 149 patients with OSA who were receiving CPAP were randomized to continue therapeutic CPAP (n = 65) or to withdraw CPAP (n = 84) for 2 weeks. Morning BP was measured at home before and after sleep studies in the hospital. CPAP withdrawal was associated with a return of OSA (apnea-hypopnea index [AHI] at a baseline of 2.8/h and at follow-up of 33.2/h). Office systolic BP (SBP) increased in the CPAP withdrawal group compared with the CPAP continuation group by +5.4 mm Hg (95% CI, 1.8-8.9 mm Hg; P = .003) and in the home SBP group by +9.0 mm Hg (95% CI, 5.7-12.3 mm Hg; P CPAP withdrawal results in a clinically relevant increase in BP, which is considerably higher than in conventional CPAP trials; it is also underestimated when office BP is used. Greater OSA severity is associated with a higher BP rise in response to CPAP withdrawal.

    Study Objectives: Posttraumatic stress disorder (PTSD) is common among veterans of the military, with sleep disturbance as a hallmark manifestation. A growing body of research has suggested a link between obstructive sleep apnea and PTSD, potentially due to obstructive sleep apnea (OSA) related sleep disruption, or via other mechanisms. We examined the hypothesis that treatment of OSA with positive airway pressure would reduce PTSD symptoms over 6 months. Methods: A prospective study of Veterans with confirmed PTSD and new diagnosis of OSA not yet using PAP therapy were recruited from a Veteran's Affairs sleep medicine clinic. All subjects were instructed to use PAP each night. Assessments were performed at 3 and 6 months. The primary outcome was a reduction in PTSD symptoms at 6 months. Results: Fifty-nine subjects were enrolled; 32 remained in the study at 6 months. A significant reduction in PTSD symptoms, measured by PCL-S score was observed over the course of the study (60.6 ± 2.7 versus 52.3 ± 3.2 points; p J Clin Sleep Med. 2017;13(1):57–63. PMID:27707436

    Residual sleepiness after continuous positive airway pressure (CPAP) is a critical problem in some patients with obstructive sleep apnea syndrome (OSAS). However, nasal surgery is likely to reduce daytime sleepiness and feelings of unrefreshed sleep. The aim of this study is to clarify the effects of nasal surgery and CPAP on daytime sleepiness. This is a retrospective and matched-case control study. The participants were consecutive 40 patients with OSAS who underwent nasal surgery (Surgery group) and 40 matched patients who were treated with CPAP (CPAP group). In the Surgery group, although the nasal surgery did not decrease either apnea or hypopnea, it improved oxygenation, the quality of sleep. In the CPAP Group, the CPAP treatment reduced apnea and hypopnea, and improved oxygenation, quality of sleep. The degree of relief from daytime sleepiness was different between the two groups. The improvement of Epworth Sleepiness Scale was more significant in the Surgery Group than those in the CPAP Group (Surgery from 11.0 to 5.1, CPAP from 10.0 to 6.2). These findings suggest that the results of the nasal surgery is more satisfactory for some patients with OSAS than CPAP on daytime sleepiness.

    Full Text Available OBJECTIVE: To determine the frequency of obstructive sleep apnea syndrome (OSAS, metabolic syndrome and common mental disorders in the working population of 11 small enterprises and the feasibility of a program of action for health. METHOD: The clinical risk of OSAS, the prevalence of metabolic syndrome, and the level of psychological disorders were assessed during routine medical examination at the workplace in 2012. The response to medical advice was assessed in 2013. RESULTS: 12.3% of the workers were suspected of being affected by OSAS. One or more components of metabolic syndrome were present in 24.5% of cases. OSAS in "healthy" workers was significantly associated with the presence of one or more components of metabolic syndrome (OR = 3.83; 95%CI 1.45-10.13 and with a psychological disorders score in the highest quartile (OR = 4.67; 95%CI = 1.72-12.64. Workers with suspected OSAS were reluctant to follow advice about undergoing further tests under the NHS. However, in some cases, confirmation of the OSAS diagnosis and subsequent treatment led to an improvement in metabolic condition. CONCLUSION: Although participation in treatment was limited, anecdotal cases support the idea that prevention of obstructive sleep apnea in the workplace might be useful for workers' health.

    Obstructive Sleep Apnea Syndrome (OSAS) is common in obese children with risk being 4.5 fold compared to normal control subjects. Polycystic Ovary Syndrome (PCOS) has recently been shown to be associated with OSAS that may further lead to significant cardiovascular and neuro-cognitive deficits. We are investigating image-based biomarkers to understand the architectural and dynamic changes in the upper airway and the surrounding hard and soft tissue structures via MRI in obese teenage children to study OSAS. At the previous SPIE conferences, we presented methods underlying Fuzzy Object Models (FOMs) for Automatic Anatomy Recognition (AAR) based on CT images of the thorax and the abdomen. The purpose of this paper is to demonstrate that the AAR approach is applicable to a different body region and image modality combination, namely in the study of upper airway structures via MRI. FOMs were built hierarchically, the smaller sub-objects forming the offspring of larger parent objects. FOMs encode the uncertainty and variability present in the form and relationships among the objects over a study population. Totally 11 basic objects (17 including composite) were modeled. Automatic recognition for the best pose of FOMs in a given image was implemented by using four methods - a one-shot method that does not require search, another three searching methods that include Fisher Linear Discriminate (FLD), a b-scale energy optimization strategy, and optimum threshold recognition method. In all, 30 multi-fold cross validation experiments based on 15 patient MRI data sets were carried out to assess the accuracy of recognition. The results indicate that the objects can be recognized with an average location error of less than 5 mm or 2-3 voxels. Then the iterative relative fuzzy connectedness (IRFC) algorithm was adopted for delineation of the target organs based on the recognized results. The delineation results showed an overall FP and TP volume fraction of 0.02 and 0.93.

    Continuous positive airways pressure (CPAP) for treatment of obstructive sleep apnea (OSA) can produce troublesome nasal symptoms (i.e. congestion, rhinorrhea) that may reduce the compliance of CPAP. Topical nasal steroids are often prescribed to reduce these side effects, although scientific data are scarce supporting any benefits of this treatment for CPAP-induced nasal side effects. To study whether a topical nasal steroid can reduce CPAP-induced nasal symptoms and improve CPAP adherence during the initial phase of OSA treatment. A randomized, double-blinded, placebo-controlled study with fluticasone propionate 100 μg/nasal cavity twice daily Treatment was started 10 days prior to and continued throughout the first 4 weeks of CPAP. 63 patients who were selected for CPAP treatment participated. Nasal symptoms were recorded, nasal patency was assessed and lung function was measured with a peak flow meter. The patients' adherence to CPAP was recorded by the CPAP device. Total nasal symptoms increased from baseline to 4 wks after CPAP use for both nasal treatments (p < 0.05). No differences in total nasal symptoms between treatments were seen (p = 1), and no differences in nasal peak flow values after treatment were seen (p = 0.11). Moreover, there were no differences in CPAP use between the treatments. Fluticasone propionate as a nasal topical steroid does not reduce CPAP-induced unwanted nasal side effects, and has no beneficial effect on CPAP compliance during the first four weeks of treatment in unselected patients with OSAS.

    Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS), but side effects are common and long-term adherence low. The Type D (distressed) personality is defined as a combination of negative affectivity and social inhibition. The association of Type D personality with adherence has not been studied in CPAP-treated patients with OSAS. This study aimed to describe the prevalence of Type D personality in OSAS patients with CPAP treatment longer than 6 months and the association with self-reported side effects and adherence. A cross-sectional descriptive design was used. A total of 247 OSAS patients with a mean use of CPAP treatment for 55 months (6-182 months) were included. Data collection was achieved by two questionnaires; the Type D scale 14 (DS14) (Type D personality), SECI (side effects of CPAP), as well as from medical records (clinical variables and objective adherence to CPAP treatment). Type D personality occurred in 30% of the patients with OSAS and significantly (P < 0.05-0.001) increased the perceived frequency and severity of a broad range of side effects. The objective adherence was significantly lower (P < 0.001) for OSAS patients with Type D compared to OSAS patients without Type D, both with regard to a mean use of 4 h per night and 85% of the self-rated sleep time per night. The additional effect of a Type D personality on perceived side effects and adherence to CPAP treatment found in this study could be used by healthcare personnel when evaluating patients waiting for treatment.

  20. Tabled Execution in Scheme

    Tabled execution is a generalization of memorization developed by the logic programming community. It not only saves results from tabled predicates, but also stores the set of currently active calls to them; tabled execution can thus provide meaningful semantics for programs that seemingly contain infinite recursions with the same arguments. In logic programming, tabled execution is used for many purposes, both for improving the efficiency of programs, and making tasks simpler and more direct to express than with normal logic programs. However, tabled execution is only infrequently applied in mainstream functional languages such as Scheme. We demonstrate an elegant implementation of tabled execution in Scheme, using a mix of continuation-passing style and mutable data. We also show the use of tabled execution in Scheme for a problem in formal language and automata theory, demonstrating that tabled execution can be a valuable tool for Scheme users.

    Full Text Available The aim of this study was to propose a mixture of micronutrients with amino acid-based foliar fertilizer as an alternative to calda viçosa for application in organic agriculture. The study was conducted in two simultaneous trials in an experimental field in Ipeúna, SP, Brazil. The test plant was carioca type dry edible bean cv. Pérola. The treatments in trial 1 were: Control 1 = water; FA = JK® amino acid-based foliar fertilizer; and FA+Mi = FA + CuSO4 + ZnSO4 + MnSO4 + H3BO3. In trial 2, the FA treatment was substituted by calda viçosa (CVi. The treatments were through spray application three times. Dry edible bean leaves were sampled for determination of macronutrient and micronutrient concentrations. Platings of the application rates used in the treatments were performed in the laboratory in a mixture with Bacillus thuringiensis and with Beauveria bassiana to compare the degree of compatibility by means of colony forming units (CFU. The FA+Mi and CVi treatments raised the concentrations of Zn, Cu, and Mn in the leaves. The FA+Mi was compatible, the FA was a stimulant, and the CVi was noxious to B. bassiana and to B. thuringiensis when integrated in the spray mixture.

    Functional imaging of the pharynx used to be the domain of cineradiography, CT and ultrafast CT. The development of modern MRI techniques led to new access to functional disorders of the pharynx. The aim of this study was to implement a new MRI technique to examine oropharyngeal obstructive mechanisms in patients with obstructive sleep apnea (OSA). Sixteen patients suffering from OSA and 6 healthy volunteers were examined on a 1.5 T whole-body imager ('Vision', Siemens, Erlangen Medical Engineering, Germany) using a circular polarized head coil. Imaging was performed with 2D flash sequences in midsagittal and axial planes. Patients and volunteers were asked to breathe normally through the nose and to simulate snoring and the Mueller maneuver during magnetic resonance imaging (MRI). Prior to MRI, all patients underwent an ear, nose and throat (ENT) examination, functional fiberoptic nasopharyngoscopy and polysomnography. A temporal resolution of 6 images/s and an in-plane resolution of 2.67x1.8 mm were achieved. The mobility of the tongue, soft palate and pharyngeal surface could be clearly delineated. The MRI findings correlated well with the clinical examinations. We propose ultrafast MRI as a reliable and non-invasive method of evaluating pharyngeal obstruction and their levels. (orig.) [de

    This study explores the association between specific insomnia symptoms (sleep onset, sleep maintenance and early morning awakenings symptoms) and self-efficacy (perceived self-confidence in the ability to use CPAP) with CPAP compliance in French patients with obstructive sleep apnea syndrome (OSAS). We performed a retrospective, cross-sectional analysis of CPAP compliance in a cohort of 404 patients diagnosed with OSAS. Patients completed mailed questionnaires on sleepiness (ESS), insomnia (ISI) and self-efficacy in sleep apnea (SEMSA). Linear regression modeling analyses were performed to explore the impact of measured variables on the number of hours of CPAP use. Of the initial pool of 404 patients, 288 returned the questionnaires (71% response rate). Their mean age was 63.16±12.73 yrs, 31% were females, mean BMI was 30.39±6.31 kg/m2, mean daily CPAP use was 6.19±2.03 h, mean number of years of use was 6.58±6.03 yrs, and mean initial AHI before CPAP use was 34.61±20.71 /h. Age (pCPAP use. We found that specific insomnia symptoms and self-efficacy were associated with CPAP compliance. Our findings underline the need to demonstrate that interventions that reduce insomnia symptoms and improve self-efficacy will increase CPAP compliance.

    2011-07-01

    Full Text Available Obstructive sleep apnea (OSA is an important public health concern, which affects around 2–4% of the population. Left untreated, it causes a decrease not only in quality of life, but also of life expectancy. Despite the fact that knowledge about the mechanisms of development of cardiovascular disease in patients with OSA is still incomplete, observations confirm a relationship between sleep disordered breathing and the rheological properties of blood. One possible consequence of an increased incidence of cardiovascular disease may be a rise in mortality in OSA patients. Continuously improved research methods are allowing for an increasingly more accurate understanding of the significance of observed changes.

    The objective of this paper is to demonstrate that structural alterations of the nasal cavity, e.g. septal deviation and conchal hypertrophy have high incidence in patients with sleep apnea and hypopnea syndrome and must be addressed with associated specific procedures of the syndrome. Clinical retrospective. A retrospective study of 200 patients was performed, with 196 male and 4 female, attended at the otorhinolaryngology ambulatory of Hospital Prof. Edmundo Vasconcelos and Unidade Paulista de Otorrinolaringologia, all of them subjected to polysomnography, otorhinolaryngological physical exam, endoscopy exam, and surgical treatment with nasal and pharyngeal procedures. All of them were subjected to pharyngeal procedure: uvulopalatopharyngoplasty or uvulopalatoplasty and nose procedure: 176 septoplasty with partial turbinectomy (88%) and 24 isolated turbinectomy, with satisfactory results. We can see that structural alterations of the nasal cavity have high incidence in patients with OSA.

    Although continuous positive airway pressure (CPAP) is effective in treating obstructive sleep apnoea (OSA), inadequate adherence remains a major cause of treatment failure. This study aimed to determine long term adherence to auto adjusting-CPAP (APAP) and its influencing factors including the role of initial compliance. Eighty-eight male patients with newly diagnosed moderate/severe OSA were included. After initiation of APAP treatment, patients had periodic follow-up appointments at 2 weeks, 6 months and then annually for at least 5 years. Patient's compliance to therapy was assessed in each appointment and predictors to treatment abandonment and poor compliance were evaluated. The studied population had a mean age of 53.8 years and mean apnoea-hypopnoea index of 52.71/h. The mean time of follow-up was 5.2 (± 1.6) years, during that time 22 (25%) patients abandoned APAP, those who maintained treatment had good compliance to it since 94% of them used it more than 4 h/day for at least 70% of days. A significant negative association was found between age, % of days and mean time of APAP use on 12th day and 6th month and the risk of abandoning. APAP use lower than 33% and 57% of days at 12th day and 6th month, respectively had high specificity (≈ 100%) to detect treatment abandonment. the majority of patients adheres to long term APAP treatment and has good compliance after 5-years of follow-up. Age and initial compliance (% days of use and mean hour/day) have the ability to predict future adherence, as soon as 12 days and 6 months after initiation. Copyright © 2013 Elsevier Ltd.

    Patients with severe OSA consume greater amounts of cholesterol, protein, and fat as well as have greater caloric expenditure. However, it is not known whether their activity levels or diet change after treatment with CPAP. To investigate this issue, serial assessments of activity and dietary intake were performed in the Apnea Positive Pressure Long-term Efficacy Study (APPLES); a 6-month randomized controlled study of CPAP vs. sham CPAP on neurocognitive outcomes. Subjects were recruited into APPLES at 5 sites through clinic encounters or public advertisement. After undergoing a diagnostic polysomnogram, subjects were randomized to CPAP or sham if their AHI was ≥ 10. Adherence was assessed using data cards from the devices. At the Tucson and Walla Walla sites, subjects were asked to complete validated activity and food frequency questionnaires at baseline and their 4-month visit. Activity and diet data were available at baseline and after 4 months treatment with CPAP or sham in up to 231 subjects (117 CPAP, 114 Sham). Mean age, AHI, BMI, and Epworth Sleepiness Score (ESS) for this cohort were 55 ± 13 [SD] years, 44 ± 27 /h, 33 ± 7.8 kg/m(2), and 10 ± 4, respectively. The participants lacking activity and diet data were younger, had lower AHI and arousal index, and had better sleep efficiency (p Level of adherence defined as hours of device usage per night at 4 months was significantly higher among men in CPAP group (4.0 ± 2.9 vs. 2.6 ± 2.6). No changes in consumption of total calories, protein, carbohydrate or fat were noted after 4 months. Except for a modest increase in recreational activity in women (268 ± 85 vs. 170 ± 47 calories, p increase in recreational activity in women, OSA patients treated with CPAP do not substantially change their diet or physical activity habits after treatment. .

    The measurement of arousals during sleep is useful to quantify sleep fragmentation. The criteria for electroencephalography (EEG) arousals defined by the American Sleep Disorders Association (ASDA) have recently been criticized because of lack of interobserver agreement. The authors have adopted a scoring method that associates the increase in chin electromyography (EMG) with the occurrence of an alpha-rhythm in all sleep stages (Université Catholique de Louvain (UCL) definition of arousals). The aim of the present study was to compare the two scoring definitions in terms of agreement and repeatability and the time taken for scoring in patients with obstructive sleep apnoea syndrome (OSAS) of varying severity. Two readers using both ASDA and UCL definitions scored twenty polysomnographies (PSGs) each on two occasions. The PSGs were chosen retrospectively to represent a wide range of arousal index (from 6-82) in OSAS patients. There was no difference in the arousal indices between readers and between scoring methods. The mean+/-SD difference between the two definitions (the bias) was 1.1+/-3.76 (95% confidence interval: -0.66-2.86). There was a strong linear relationship between the arousal index scored with the two definitions (r=0.981, pASDA definitions (18.5+/-5.4 versus 25.3+/-6.6 min, p<0.001). In conclusion, it has been found that in obstructive sleep apnoea syndrome patients, the American Sleep Disorders Association and Université Catholique de Louvain definitions were comparable in terms of agreement and repeatability.

    Poor adherence to CPAP treatment in OSA adversely affects the effectiveness of this therapy. This randomized controlled trial (RCT) examined the efficacy of a brief motivational enhancement education program in improving adherence to CPAP treatment in subjects with OSA. Subjects with newly diagnosed OSA were recruited into this RCT. The control group received usual advice on the importance of CPAP therapy and its care. The intervention group received usual care plus a brief motivational enhancement education program directed at enhancing the subjects' knowledge, motivation, and self-efficacy to use CPAP through the use of a 25-min video, a 20-min patient-centered interview, and a 10-min telephone follow-up. Self-reported daytime sleepiness adherence-related cognitions and quality of life were assessed at 1 month and 3 months. CPAP usage data were downloaded at the completion of this 3-month study. One hundred subjects with OSA (mean ± SD, age 52 ± 10 years; Epworth Sleepiness Scales [ESS], 9 ± 5; median [interquartile range] apnea-hypopnea index, 29 [20, 53] events/h) prescribed CPAP treatment were recruited. The intervention group had better CPAP use (higher daily CPAP usage by 2 h/d [Cohen d = 1.33, P motivational enhancement education in addition to usual care were more likely to show better adherence to CPAP treatment, with greater improvements in treatment self-efficacy and daytime sleepiness.

    Since the control rate of blood pressure is lower in mainland China, the aim of this study is to investigate the proportion of secondary causes and coexisting diseases of hypertension in hypertensive patients. Data on consecutive patients with hypertension who visited the Hypertension Center. Diseases were detected using an established strict screening protocol. Detection rate of secondary causes and coexisting diseases of hypertension was 39.5% among 3003 hypertensive patients. Obstructive sleep apnea (OSA) was the most common, accounting for 24.7% of patients, followed by primary aldosteronism (PA) (5.8%) and PA + OSA (4.9%). Endocrine hypertension accounted for 12.1% of patients, including 10.7% of patients with PA, 1.1% with hypothyroidism, 0.1% with pheochromocytoma, 0.1% with Cushing's syndrome, and 0.1% with hyperthyroidism, respectively. Those who smoke, those who are obese, and those who have diabetes accounted for 31.3%, 27.5%, and 16.6% of total patients, respectively. There were overlapping conditions in secondary causes and coexisting diseases of hypertension. OSA was the most common in each age- and BMI-stratified group. Findings from the current study suggest an increasing frequency of secondary forms of hypertension, highlighting the burden of OSA and PA in hypertensive patients.

    Obstructive sleep apnea (OSA) has been associated with hypertension, which is one of the intermediary mechanisms leading to increased cardiovascular morbidity. This study aimed at evaluating the effects of a combination of continuous positive airway pressure (CPAP) and telemedicine support on blood pressure (BP) reduction in high cardiovascular risk OSA patients. A multi-center randomized controlled trial that compared standard CPAP care and CPAP care and a telemedicine intervention. Sleep clinics in France. 107 adult (18-65 years old) OSA patients (AHI > 15 events/h) with a high cardiovascular risk (cardiovascular SCORE > 5% or secondary prevention). Patients were randomized to either standard care CPAP (n = 53) or CPAP and telemedicine (n = 54). Patients assigned to telemedicine were equipped with a smartphone for uploading BP measurements, CPAP adherence, sleepiness, and quality of life data; in return, they received pictograms containing health-related messages. The main outcome was home self-measured BP and secondary outcomes were cardiovascular risk evolution, objective physical activity, CPAP adherence, sleepiness and quality of life. Self-measured BP did not improve in either group (telemedicine or standard care). Patients in primary prevention showed greater BP reduction with CPAP treatment than those in secondary prevention. CPAP treatment supported by telemedicine alone did not improve blood pressure and cardiovascular risk in high cardiovascular risk OSA patients. This study emphasizes the need for diet and physical activity training programs in addition to CPAP when aiming at decreasing cardiometabolic risk factors in these patients.

    The aim of this study was to identify possible upper airway obstructions causing a higher continuous positive airway pressure (CPAP) titration level, utilizing drug-induced sleep endoscopy (DISE). A total of 76 patients with obstructive sleep apnea (OSA) underwent CPAP titration and DISE. DISE findings were recorded using the VOTE classification system. Polysomnographic (PSG) data, anthropometric variables, and patterns of airway collapse during DISE were analyzed with CPAP titration levels. A significant association was found between the CPAP titration level and BMI, oxygen desaturation index (ODI), apnea-hypopnea index (AHI), and neck circumference (NC) (P CPAP titration level (P CPAP titration level and any other collapse at the tongue base or epiglottis. By analyzing PSG data, anthropometric variables, and DISE results with CPAP titration levels, we can better understand possible mechanisms resulting in a higher CPAP titration level. We believe that the role of DISE can be expanded as a tool to identify the possible anatomical structures that may be corrected by oral appliance therapy or surgical intervention to improve CPAP compliance.

Different reports have disclosed the association between sleep and cognition in adults and in children, as well as the impact of disturbed sleep on various aspects of neuropsychological functioning and behavior in children and adolescents. Behavioral and cognitive dysfunctions can also be considered as related to alterations in the executive functions (EF system. In particular, the EF concept refers to self-regulatory cognitive processes that are associated with monitoring and controlling both thought and goal directed behaviors. The aim of the present study is to assess the impact of the obstructive sleep apnea syndrome (OSAS on EF in a large sample of school aged children. Materials and methods: The study population comprised 79 children (51 males and 28 females aged 7–12 years (mean 9.14 ± 2.36 years with OSAS and 92 healthy children (63 males and 29 females, mean age 9.08 ± 2.44 years. To identify the severity of OSAS, an overnight respiratory evaluation was performed. All subjects filled out the Italian version of the Modified Card Sorting Test to screen EFs.

    Executive functions are thinking skills that assist with reasoning, planning, problem solving, and managing one’s life. The brain areas that underlie these skills are interconnected with and influenced by activity in many different brain areas, some of which are associated with emotion and stress. One consequence of the stress-specific connections is that executive functions, which help us to organize our thinking, tend to be disrupted when stimulation is too high and we are stressed out, or too low when we are bored and lethargic. Given their central role in reasoning and also in managing stress and emotion, scientists have conducted studies, primarily with adults, to determine whether executive functions can be improved by training. By and large, results have shown that they can be, in part through computer-based videogame-like activities. Evidence of wider, more general benefits from such computer-based training, however, is mixed. Accordingly, scientists have reasoned that training will have wider benefits if it is implemented early, with very young children as the neural circuitry of executive functions is developing, and that it will be most effective if embedded in children’s everyday activities. Evidence produced by this research, however, is also mixed. In sum, much remains to be learned about executive function training. Without question, however, continued research on this important topic will yield valuable information about cognitive development. PMID:27906522

    Full Text Available This study examines the spatial extent of coastal urban development and its potential sensitivity to sea-level rise. The main aim of the study is to critically examine the extent of growth in Eti-Osa over time, and the potential impacts of sea leve rise. Landsat Enhanced Thematic Mapper Plus (ETM+ imageries of years 2000 and 2015 were used to evaluate the different land use type identified. Post-classification change detection method was used to evaluate the output of the maximum likelihood supervised classification analysis done. This was also used to estimate the changes induces through urban development on the environment which accounts for the biodiversity loss. ASTER GDEM 2 imagery of 2011 was used to generate the elevation data used for the inundation analysis. Thus, both Land use map of Eti-Osa in 2015 and the down scaled Sea-level rise scenarios (at 0.5 to 15 meters were used for the inundation mapping. Results obtained from this research affirms that indeed EtiOsa has been subjected to gross urban expansion giving room for diverse forms of environmental degradation among which are huge replacement of natural land cover with built-up, reclamation of wetlands and sand filling of water bodies. This basically illustrates growth but also the risk that accompanies the advent of excessive alteration of natural ecosystem as Sea-level rise projections imply in this research.

  4. Executions in The Bahamas

    Full Text Available The stories of those who have been executed in the Bahamas are heretofore untold. In telling these stories and in linking them to the changing course of Bahamian history, the present research adds an important dimension to our understanding of Bahamian history and politics. The major theme of this effort is that the changing practice of the death penalty is much more than a consequence of changes in crime. The use of the death penalty parallels the changing interests of colonial rulers, the changing practice of slavery, and the changing role of the Bahamas in colonial and regional affairs. Four distinctive eras of death penalty practice can be identified: (1 the slave era, where executions and commutations were used liberally and with a clear racial patterning; (2 a long era of stable colonialism, a period of marginalization and few executions; (3 an era of unstable colonialism characterized by intensive and efficient use of the death penalty; and (4 the current independence era of high murder rates and equally high impediments to the use of executions.

    Study Objectives: Obstructive sleep apnea syndrome (OSAS) patients benefit from continuous positive airway pressure (CPAP) treatment in a dose-response manner. We determined adherence and weight control, as well as their predictors, among long-term CPAP users. Methods: Cohort of 1,023 OSAS patients had used CPAP on average of 6.6 ± 1.2 years. BMI was determined at baseline and at follow-up visits. There were 7.4 ± 1.7 BMI and 6.5 ± 1.8 CPAP usage measurements per patient on average. Using the Bayesian hierarchical model, we determined the patients' individual trends of BMI and adherence development. Patients with significantly increasing or decreasing trends were identified at the posterior probability level of > 90%. Results: The mean age in the cohort was 55.6 ± 9.8 years, BMI 33.5 ± 6.4 kg/m2, apnea-hypopnea index 33.7 ± 23.1, and CPAP usage 6.0 ± 1.8 h/day. The majority of patients had no significant change in BMI (mean annual weight gain 0.04 ± 0.29 kg/m2) or CPAP adherence (mean annual increase 11.4 ± 7.0 min/day). However, at the individual level, 10% of the patients showed significant annual weight gain (0.63 ± 0.35 kg/m2) during the 5-year follow-up period. At baseline these patients were already more severely obese (mean BMI 40.0 ± 5.9 kg/m2) despite being younger (mean 50.9 ± 9.5 years) than the rest of the cohort. Conclusions: In the majority of CPAP-treated OSAS patients, weight did not significantly change but gained slightly slower than in age-matched population in general. However, in 10% of patients, high adherence to CPAP treatment did not prevent the continuation of weight gain. These patients present a high-risk group for OSAS-related multimorbidity later in life.

  10. EXECUTIVE FUNCTIONING IN SCHIZOPHRENIA

    Directory of Open Access Journals (Sweden)

    Gricel eOrellana

    2013-06-01

    Full Text Available The executive function (EF is a set of abilities, which allows us to invoke voluntary control of our behavioral responses. These functions enable human beings to develop and carry out plans, make up analogies, obey social rules, solve problems, adapt to unexpected circumstances, do many tasks simultaneously and locate episodes in time and place. EF includes divided attention and sustained attention, working memory, set-shifting, flexibility, planning and the regulation of goal directed behavior and can be defined as a brain function underlying the human faculty to act or think not only in reaction to external events but also in relation with internal goals and states. EF is mostly associated with dorsolateral prefrontal cortex (PFC. Besides EF, PFC is involved in self-regulation of behavior, i.e. the ability to regulate behavior according to internal goals and constraints, particularly in less structured situations. Self-regulation of behavior is subtended by ventral medial /orbital PFC. Impairment of EF is one of the most commonly observed deficits in schizophrenia through the various disease stages. Impairment in tasks measuring conceptualization, planning, cognitive flexibility, verbal fluency, ability to solve complex problems and working memory occur in schizophrenia. Disorders detected by executive tests are consistent with evidence from functional neuroimaging, which have shown PFC dysfunction in patients while performing these kinds of tasks. Schizophrenics also exhibit deficit in odor identifying, decision-making and self-regulation of behavior suggesting dysfunction of the orbital PFC. However, impairment in executive tests is explained by dysfunction of prefronto-striato-thalamic, prefronto-parietal and prefronto-temporal neural networks mainly. Disorders in executive functions may be considered central facts with respect to schizophrenia and it has been suggested that negative symptoms may be explained by that executive dysfunction.

  12. What executives should remember.

    Drucker, Peter F

    2006-02-01

    In more than 30 essays for Harvard Business Review, Peter Drucker (1909-2005) urged readers to take on the hard work of thinking--always combined, he insisted, with decisive action. He closely analyzed the phenomenon of knowledge work--the growing call for employees who use their minds rather than their hands--and explained how it challenged the conventional wisdom about the way organizations should be run. He was intrigued by employees who knew more about certain subjects than their bosses or colleagues but who still had to cooperate with others in a large organization. As the business world matured in the second half of the twentieth century, executives came to think that they knew how to run companies--and Drucker took it upon himself to poke holes in their assumptions, lest organizations become stale. But he did so sympathetically, operating from the premise that his readers were intelligent, hardworking people of goodwill. Well suited to HBR's format of practical, idea-based essays for executives, his clear-eyed, humanistic writing enriched the magazine time and again. This article is a compilation of the savviest management advice Drucker offered HBR readers over the years--in short, his greatest hits. It revisits the following insightful, influential contributions: "The Theory of the Business" (September-October 1994), "Managing for Business Effectiveness" (May-June 1963), "What Business Can Learn from Nonprofits" (July-August 1989), "The New Society of Organizations" (September-October 1992), "The Information Executives Truly Need" (January-February 1995), "Managing Oneself" (March-April 1999 republished January 2005), "They're Not Employees, They're People" (February 2002), "What Makes an Effective Executive" (June 2004).

    Full Text Available La lista de plantas que compone este breve artículo fue confeccionada extrayendo los datos respectivos de la obra "Woods of Northeastern Peru" de Llewelyn Williams, publicada en FIELD MUSEUMOF NATURAL, HISTORY,BOTANICALSERIES, Vol. 15, pp. 1-509; 1936. En dicha obra el señor Williams cataloga -entre muchas otras de distintas regiones de la Amazonia peruana-- un buen numero de plantas leñosas coleccionadas por él en la hacienda "La Victoria", muy cerca de Leticia, haciéndolas figurar como del Perú. Esto se debe a que en la época que Williams visito aquella región hoy colombiana -a mediados de 1929- no se había perfeccionado todavía, o mejor dicho, no se había puesto en práctica (aunque ya estaba promulgado solemnemente el tratado de fronteras entre Colombia y el Perú que puso fin al litigio que estos dos países sostuvieron por más de un siglo sobre una gran parte del territorio selvoso que se extiende entre los ríos Caquetá y Amazonas. Digo que no se había puesto en practica dicho tratado porque, si bien se firmó el 24 de marzo de 1922 y se promulgo el 31 de marzo de 1938, sólo vino a ejecutarse in situ el 17 de agosto de 1930, después de localizada y amojonada la frontera, mediante la formalidad del acto de entrega y de recibo de los territorios que les tocó definitivamente a un país y al otro. Fue, pues, un año después de la visita de Williams a dicha región cuando la bandera y las autoridades colombianas reemplazaron efectivamente a las peruanas en el llamado "Trapecio Amazónico", cuya población principal es Leticia, sobre el rio Amazonas.

    In previous work we developed a framework of computational models for the concurrent execution of functions on different levels of abstraction. It shows that the traditional sequential execution of function is just a possible implementation of an abstract computational model that allows for the concurrent execution of functions. We use this framework as base for the development of abstract computational models that allow for the concurrent execution of objects.

    Obstructive sleep apnea (OSA) is a widespread condition that adversely affects physical health and cognitive functioning. The prevailing treatment for OSA is continuous positive airway pressure (CPAP), but therapeutic benefits are dependent on consistent use. Our goal was to investigate the relationship between CPAP adherence and measures of sustained attention in patients with OSA. Our hypothesis was that the Psychomotor Vigilance Task (PVT) would be sensitive to attention-related improvements resulting from CPAP use. This study was a secondary analysis of a larger clinical trial. Treatment adherence was determined from CPAP use data. Validated sleep-related questionnaires and a sustained-attention and alertness test (PVT) were administered to participants at baseline and at the 6-month time point. Over a 6-month time period, the average CPAP adherence was 3.32 h/night (standard deviation [SD] = 2.53), average improvement in PVT minor lapses was -4.77 (SD = 13.2), and average improvement in PVT reaction time was -73.1 milliseconds (standard deviation = 211). Multiple linear regression analysis showed that higher CPAP adherence was significantly associated with a greater reduction in minor lapses in attention after 6 months of continuous treatment with CPAP therapy (β = -0.72, standard error = 0.34, P = .037). The results of this study showed that higher levels of CPAP adherence were associated with significant improvements in vigilance. Because the PVT is a performance-based measure that is not influenced by prior learning and is not subjective, it may be an important supplement to patient self-reported assessments.

    Obstructive sleep apnea syndrome (OSA) afflicts approximately 5% of the adult population and increases with age. The gold standard treatment is with the Continuous Positive Airways Pressure (CPAP) machine. Well-designed prospective trials to elucidate long term compliance with CPAP machine are rare. Assessing compliance and long-term use of CPAP machines among patients with OSA who were referred for treatment with this machine. A 4 years prospective cohort observational study was conducted using telephone interviews of 371 newly diagnosed patients with moderate to severe OSA, who received a specialist recommendation to use the CPAP machine which was bought and adjusted to their use. At the end of the first year, 126 (34%) of the OSA patients used the CPAP machine on a nightly basis (regular users), 120 (32.3%) had not used it at all, and 125 (33.7%) had used it only intermittently. The number of regular users increased between the 1st and 2nd year from 126 (34%), to 163 (44%) (p < 0.07) due to additions from the intermittent users group. The non-users group grew from 120 (32.3%) in the first year, and every year afterwards, up to 221 (59.6%) in the fourth year (p < 0.02). In contrast, there was a significant decrease in the intermittent users group, which declined from 125 (33.7%) in the first year to only 18 (4.8%) in the 4th year (p < 0.005). Most of the patients (92.9%) were males. The average age of the regular users was 59.6 years (+/- 11), which was higher in comparison to 55.9 years (+/- 10.3) for the non-users or 58.9 years (+/- 12.6) among the intermittent users (p = 0.064). There were no statistical differences in co-morbidities or demographics between the three groups. However, the regular users were found to have a higher score in the Epworth Sleepiness Scale (ESS) and a minimal arterial oxygen saturation (SaO2) level lower than the patients in the non-users and intermittent users groups (p = 0.019 and p = 0.03 respectively).

    Obstructive sleep apnea (OSA) and posttraumatic stress disorder (PTSD) are common in United States veterans. These conditions often coexist and symptoms overlap. Previous studies reported improvement in PTSD symptoms with continuous positive airway pressure (CPAP) therapy for comorbid OSA but its effect has not been assessed in a non-PTSD cohort. We have prospectively assessed the effect of CPAP therapy on clinical symptom improvement as a function of CPAP compliance levels among PTSD and non-PTSD veterans. Veterans in whom OSA was newly diagnosed were enrolled in our study (n = 192). Assignment to PTSD and non-PTSD cohorts was determined by chart review. Each patient completed the military version of the PTSD Checklist (PCL), Epworth Sleepiness Scale (ESS), and reported nightmare frequency (NMF) at baseline and 6 months after CPAP therapy. CPAP adherence was objectively documented from machine compliance data. We had complete data for 177 veterans (PTSD n = 59, non-PTSD n = 118) for analysis. The mean ages were 51.24 years in the PTSD cohort and 52.36 years in the non-PTSD cohort ( P = .30). In the PTSD cohort, the mean total PCL score (baseline = 66.06, post-CPAP = 61.27, P = .004, d = -0.34) and NMF (baseline = 4.61, post-CPAP = 1.49, P = .0001, d = -0.51) decreased after 6 months of CPAP treatment. Linear regression analysis showed that the CPAP compliance was the only significant predictor for these changes among veterans with PTSD (PCL score: P = .033, R 2 = .65; NMF; P = .03, R 2 = .61). Further analysis by CPAP compliance quartiles in this cohort (Q1 = 0% to 25%, Q2 = 26% to 50%, Q3 = 51% to 75%, Q4 > 75%) revealed that mean total PCL score declined in Q2 (change = -3.91, P = .045, d = 0.43), Q3 (change = -6.6, P = .002, d = 0.59), and Q4 (change = -7.94, P = .037, d = 0.49). In the non-PTSD cohort, the PCL score increased despite CPAP therapy in lower CPAP compliance quartiles Q1 (change = 8.71, P = .0001, d = 0.46) and Q2 (change = 4.51, P = .046, d = 0

    Energy Technology Data Exchange (ETDEWEB)

    2017-04-21

    At exascale, the challenge becomes to develop applications that run at scale and use exascale platforms reliably, efficiently, and flexibly. Workflows become much more complex because they must seamlessly integrate simulation and data analytics. They must include down-sampling, post-processing, feature extraction, and visualization. Power and data transfer limitations require these analysis tasks to be run in-situ or in-transit. We expect successful workflows will comprise multiple linked simulations along with tens of analysis routines. Users will have limited development time at scale and, therefore, must have rich tools to develop, debug, test, and deploy applications. At this scale, successful workflows will compose linked computations from an assortment of reliable, well-defined computation elements, ones that can come and go as required, based on the needs of the workflow over time. We propose a novel framework that utilizes both virtual machines (VMs) and software containers to create a workflow system that establishes a uniform build and execution environment (BEE) beyond the capabilities of current systems. In this environment, applications will run reliably and repeatably across heterogeneous hardware and software. Containers, both commercial (Docker and Rocket) and open-source (LXC and LXD), define a runtime that isolates all software dependencies from the machine operating system. Workflows may contain multiple containers that run different operating systems, different software, and even different versions of the same software. We will run containers in open-source virtual machines (KVM) and emulators (QEMU) so that workflows run on any machine entirely in user-space. On this platform of containers and virtual machines, we will deliver workflow software that provides services, including repeatable execution, provenance, checkpointing, and future proofing. We will capture provenance about how containers were launched and how they interact to annotate

    For six years, Cynthia Cunningham and Shelley Murray shared an executive job at Fleet Bank. One desk, one chair, one computer, one telephone, and one voice-mail account. To their clients and colleagues, they were effectively one person, though one person with the strengths and ideas of two, seamlessly handing projects back and forth. Although their department was dissolved after the bank merged with Bank of America, the two continue to consider themselves a package-they have one resume, and they are seeking their next opportunity together. Their choice to share a job was not only a quality-of-life decision but one intended to keep their careers on course: "Taking two separate part-time jobs would have thrown us completely off track" they write in this first-person account."We're both ambitious people, and neither of us wanted just a job. We wanted careers" In this article, the two highly motivated women reveal their determination to manage the demands of both family and career. Flextime,telecommuting, and compressed workweeks are just some of the options open to executives seeking greater work/ life balance, and the job share, as described by Cunningham and Murray, could well be the next solution for those wishing to avoid major trade-offs between their personal and professional lives. Cunningham and Murray describe in vivid detail how they structured their unusual arrangement, how they sold themselves to management, and the hurdles they faced along the way. Theirs is a win-win story, for the company and for them.

    Full Text Available The forestry sector is not only formed by large companies, such as pulp and paper or reconstituted panels, but also by small businesses, and often strictly family businesses, as joineries. This study aimed to identify, assess and characterize joineries in Viçosa, Minas Gerais. The object of study was limited to the city’s joinery businesses, mainly the ones belonging to the former Joiner’s Association. A questionnaire was drawn up to obtain information on the used wood, internal management and employee training, machinery, products, market, product advertising and prospects for the sector. It was found that both entrepreneurs and workers have low educational level and lack their own product design. They were producing only ordered products with intensive use of solid wood particularly from native forests. Products were heterogeneous, ranging from furniture to farm utilities. Competition, mainly the informal, represented the biggest obstacle to sector development, as well as serialized products from other locations sold in shops at lower prices. It was concluded that the joinery sector in Viçosa needs greater skill levels, both technical and managerial, to improve the activity. Moreover, the sector needs better organization through associations and support of agencies such as local Sebrae, and wider product advertising targeting consumers in the region.O setor florestal não é constituído apenas por grandes empresas, como as de celulose e papel ou de painéis reconstituídos, mas também por pequenas empresas, muitas das vezes estritamente familiares, como as marcenarias.

    A. M. Waldschmidt

    Full Text Available With uncontrolled deforestation, forest fragments remain, which in most cases are in different stages of regeneration and present isolated populations. In the present study we analyzed the genetic patterns of Eulaema nigrita populations in seven Atlantic Forest fragments of different sizes and successional stages in the region of Viçosa, MG. This was done by RAPD molecular markers. We observed that the area of the fragments had no effect on the genetic variability of E. nigrita in the direction predicted by meta-population models. Medium-sized well-preserved woods presented the lowest variability, whereas large and small woods were statistically identical. The evidence supports the notion that rural areas present greater dispersal among fragments, implying greater similarity between the populations of fragments located in rural areas when compared to fragments in urban areas.

    Heated humidifiers (HH) enable effective treatment of upper airway dryness during nasal continuous positive airway pressure (nCPAP) therapy for obstructive sleep apnoea (OSA), but the role of prophylactic use of HH during the initiation of nCPAP treatment has not been studied so far. The aim of the present study was to investigate whether prophylactic HH during the initiation of CPAP would result in improved initial patient comfort and acceptance. In 44 consecutive, previously untreated OSA patients with no history of upper airway dryness, CPAP titration with and without HH was performed on two consecutive nights in a randomised order. The patients were interviewed after each treatment night in order to establish the comfort of the treatment, and, after the second treatment, they were asked which of the two nights they considered more pleasant, and which treatment they would prefer for long-term use. Following CPAP titration with HH, 32 patients (73%) claimed to have had a better night's sleep than usual (i.e. without CPAP treatment) compared with 33 patients (75%) saying the same following CPAP treatment without HH. For 21 patients (47.7%) treatment with HH was more pleasant, 23 (52.3%) saw no difference or said that treatment without HH was more pleasant. Nineteen patients (43.2%) gave preference to treatment with HH for long-term use, while 25 patients (56.8%) had no preference or said they would prefer treatment without HH. The use of HH during the initiation phase of CPAP treatment was associated neither with an initial improvement in comfort nor with greater initial treatment acceptance. Copyright 2002 S.

In February and March of 2000 most of the trees of this species produced a large fruit crop, compared with 1995-1999, when the number of fruit producing trees was very low or zero and those that did bear fruit, did so at a low intensity. In contrast, the fruit crop of 2000 was massive, all trees examined produced fruits and the intensity of fruiting was maximal.

    Full Text Available Background: Berlin Questionnaire (BQ, an English language screening tool for obstructive sleep apnea (OSA in primary care, has been applied in tertiary settings, with variable results. Aims: Development of BQ Portuguese version and evaluation of its utility in a sleep disordered breathing clinic (SDBC. Material and methods: BQ was translated using back translation methodology and prospectively applied, previously to cardiorespiratory sleep study, to 95 consecutive subjects, referred to a SDBC, with OSA suspicion. OSA risk assessment was based on responses in 10 items, organized in 3 categories: snoring and witnessed apneas (category 1, daytime sleepiness (category 2, high blood pressure (HBP/obesity (category 3. Results: In the studied sample, 67.4% were males, with a mean age of 51 ± 13 years. Categories 1, 2 and 3 were positive in 91.6, 24.2 and 66.3%, respectively. BQ identified 68.4% of the patients as being in the high risk group for OSA and the remaining 31.6% in the low risk. BQ sensitivity and specificity were 72.1 and 50%, respectively, for an apnea-hipopnea index (AHI > 5, 82.6 and 44.8% for AHI > 15, 88.4 and 39.1% for AHI > 30. Being in the high risk group for OSA did not infl uence significantly the probability of having the disease (positive likelihood ratio [LR] between 1.44-1.49. Only the items related to snoring loudness, witnessed apneas and HBP/obesity presented a statistically positive association with AHI, with the model constituted by their association presenting a greater discrimination capability, especially for an AHI > 5 (sensitivity 65.2%, specificity 80%, positive LR 3.26. Conclusions: The BQ is not an appropriate screening tool for OSA in a SDBC, although snoring loudness, witnessed apneas, HBP/obesity have demonstrated being significant questionnaire elements in this population.

    Objective: To investigate the changes of plasma IL-6 and TNF-α levels after continuous positive airway pressure (CPAP) therapy in patients with obstructive sleep apnea syndrome (OSAS). Methods: Plasma IL-6 and TNF-α levels were measured with RIA in 60 patients with OSAS both before and after CPAS therapy as well as in 30 controls. Results: Before CPAP therapy, the plasma IL-6 and TNF-α levels in patients with OSAS were significantly higher than those in controls (25.92 ± 4.48pg/ ml and 11.27 ± 2.60pg/ml vs 13.21 ± 1.97pg/ml and 5.83±0.99pg/mi, P 2 level (r=-0.495, 0.483, P<0.05). After treatment with CPAP for three months, the plasma IL-6 and TNF-α levels were significantly decreased (15.37±1.78pg/ml and 6.79±0.87pg/ml, vs pre-treatment levels, P<0.05, P<0.01). Conclusion: CPAP therapy could effectively decrease the plasma IL-6 and TNF-α levels in patients with OSAS. (authors)

    Continuous positive airway pressure (CPAP) delivered by nasal mask is the gold standard treatment for obstructive sleep apnea (OSA). However, oral and oronasal masks are also available. We considered experimental evidence and reviewed clinical trials that evaluated the impact of oral and oronasal mask on OSA treatment. One recent study in 18 OSA patients that slept with a customized oronasal mask with two sealed compartments showed that the change of CPAP flow from nasal to oronasal and oral caused upper airway obstruction because of posterior displacement of the tongue demonstrated by nasoendoscopy. Oral masks use a mouthpiece that may stabilize the jaw and the tongue and have shown to be effective. However, oral masks are not widely used in clinical practice. Four out of five observational studies and all five reviewed randomized studies showed a worse performance of oronasal when compared with nasal masks. Oronasal masks were associated with higher residual apnea-hypopnea index, lower adherence, more leaks, and less satisfaction than nasal mask in the majority of the studies. Nasal CPAP must be the first choice to treat OSA. Patients on oronasal mask should be carefully followed. VIDEO ABSTRACT.

    Full Text Available Indicadores locais são úteis para a identificação de ambientes. Na região de Viçosa, embora os solos encharcados ocorram sob vegetação de taboa (Thypha dominguensis, Gleissolos, de coloração típica acinzentada, são incomuns. A maioria dos solos com lençol freático alto é coberta pela taboa e as características gleizadas do solo são pouco pronunciadas, especialmente nos solos com mais altos teores de ferro. Não há clara conexão entre altura do lençol freático e deficiência de oxigênio. Como as relações entre altura do lençol freático, deficiência de oxigênio e cor do solo não são claras o bastante, hipotetizou-se que outros indicadores para as condições de redução poderiam ser encontrados nesses ambientes. Neste propósito, caracterizou-se o solo e trabalhou-se na sua relação com a vegetação. Estudaram-se os solos com várias intensidades de condições de drenagem em três áreas: Cajuri (Área 1, Viçosa (Área 2 e Coimbra (Área 3, todas pertencentes ao Planalto de Viçosa. Na avaliação das condições de redox dos solos (pH e pE a campo, utilizou-se um medidor digital adaptado a uma sonda de aço. Conquanto importante na identificação de indicadores de ambientes, a caracterização morfológica não se mostrou precisa o bastante para evidenciar o que os solos encharcados têm mais em comum: a deficiência de oxigênio por longos períodos. A cor, embora seja um bom e útil indicador para muitas das condições de drenagem do solo, não se mostrou também eficiente nessas áreas. De modo geral, os Gleissolos estudados apresentaram cromas maiores do que dois, o que supera o limite do critério para identificar horizonte glei no Sistema Brasileiro de Classificação de Solos, embora o teste indicador da presença de Fe2+ com alfa,alfa'-dipiridil tenha sido positivo.

    Children spend a lot of time watching television on its many platforms: directly, online, and via videos and DVDs. Many researchers are concerned that some types of television content appear to negatively influence children's executive function. Because (1) executive function predicts key developmental outcomes, (2) executive function appears to be influenced by some television content, and (3) American children watch large quantities of television (including the content of concern), the issues discussed here comprise a crucial public health issue. Further research is needed to reveal exactly what television content is implicated, what underlies television's effect on executive function, how long the effect lasts, and who is affected. © 2015 Elsevier Inc.

    Research purpose: The purpose of this article is to address the training and development needs of these consulting psychologists by presenting a competence executive coaching model for the planning, implementation and evaluation of executive coaching interventions. Research design, approach and method: The study was conducted while one of the authors was involved in teaching doctoral students in consulting psychology and executive coaching, specifically in the USA. The approach involved a literature review of executive coaching models and a qualitative study using focus groups to develop and evaluate the competence executive coaching model. Main findings: The literature review provided scant evidence of competence executive coaching models and there seems to be a specific need for this in the training of coaches in South Africa. Hence the model that was developed is an attempt to provide trainers with a structured model for the training of coaches. Contribution/value-add: The uniqueness of this competence model is not only described in terms of the six distinct coaching intervention phases, but also the competencies required in each.

    Post-stroke Depression, Obstructive sleep apnea (OSA) and Cognitive impairment ("DOC") are associated with greater mortality, worse recovery and poorer quality of life. Best practice recommendations endorse routine screening for each condition; yet, all are under-assessed, diagnosed and treated. We seek to determine the feasibility and validity of an integrated tool ("DOC" screen) to identify stroke clinic patients at high-risk of depression, OSA, and cognitive impairment. All consecutive new referrals to a regional Stroke Prevention Clinic who were English-speaking and non-aphasic were eligible to be screened. Time for screen completion was logged. DOC screen results were compared to the neuropsychological battery and polysomnogram assessments using a modified receiver operator characteristic and area under the curve analysis. Data is reported to conform to STARD guidelines. 1503 people were screened over 2 years. 89% of eligible patients completed the screen in 5 minutes or less (mean 4.2 minutes), less than half the time it takes to complete the Montreal Cognitive Assessment (MoCA). 437 people consented to detailed testing. Of those, 421 completed the Structured Clinical Interview for Depression within 3 months of screening, 387 completed detailed neuropsychological testing within 3 months, and 88 had overnight polysomnograms. Screening scores combined with demographic variables (age, sex, education, body mass index), had excellent validity compared to gold standard diagnoses: DOC-Mood AUC 0.90; DOC-Apnea AUC 0.80; DOC-Cog AUC 0.81. DOC screen scores can reliably categorize patients in to low-, intermediate- or high-risk groups for further action and can do so with comparable accuracy to more time-consuming screens. Systematic screening of depression, obstructive sleep apnea, and cognitive impairment in 5 minutes or less is feasible and valid in a high volume stroke clinic using the DOC screen. The DOC screen may facilitate improved identification and treatment

    A New Energy Vision was formulated for Osa Town after investigations about energy demand, new energy reserves, and their available amounts. The town consumes approximately 50.6-billion kcal in total, with automobiles consuming a half thereof as fuel. Studies were made about new energy reserves and recoverable amounts in the town, and then an estimation was made that 16.2 times 10{sup 5} kWh/year would be recoverable from photovoltaic energy, 1.58 times 10{sup 5} kWh from small-scale hydropower, 8.79 times 10{sup 6} kWh from ligneous biomass, and 1.96 times 10{sup 5} kWh from livestock biomass, and that 40 MW, for example, would come from wind power, subject to change depending on the wind power generator system to be built. Projects for new energy introduction were discussed, which involved the use of biodiesel fuel for official vehicles, installation of solar hot water showers in primary and junior high schools, application of photovoltaic/wind power to crime prevention lights and street lamps, snow melting systems for roads utilizing geothermal energy, use of heat from thinnings and ligneous waste, wind power facilities, small-scale hydropower facilities, introduction of new energy appliances into sightseeing facilities, and the introduction of photovoltaic power or the like into public facilities.

    Full Text Available La contaminación en los ríos de Costa Rica es un problema que merece especial atención. El concepto “contaminación del agua” implica la incorporación de materias extrañas a esta, tales como microorganis- mos (coliformes totales y fecales, productos quími- cos (jabones, fer tilizantes, pesticidas, metales pesados (cromo, plomo, mercurio, etc. o materia orgánica proveniente de los suelos a través de la escorrentía superficial y de las aguas residuales domésticas. Estas materias deterioran la calidad del agua y reducen los diferentes usos que podría tener un río. El recurso hídrico es importante tanto para la preservación de la vida humana como para la conservación de la flora y fauna. Costa Rica se ha caracterizado por ser un país poseedor de una rica biodiversidad. Sin embargo, muchos de los ríos de la Gran Área Metropolitana ya presentan una contaminación severa, según el Índice holandés de clasificación de la calidad del agua. En este estudio se analizó el contenido de colifor- mes fecales en 10 ríos de las provincias de San José, Alajuela, Heredia y Car tago, así como de la Península de Osa. Para correlacionar el contenido de colifor- mes fecales con la densidad poblacional, además, se muestrearon tres puntos en cada río: la zona alta cercana a la naciente, la zona media y la zona baja cercana a su desembocadura. Se encontró que los puntos de muestreo con densi- dades poblacionales medias o altas están altamente contaminados con coliformes fecales.Varios de ellos superan el límite máximo permisible en el contenido de coliformes fecales establecido por los reglamen- tos nacionales para el uso de los ríos en actividades de recreación de contacto primario.

Faced with a severe financial crisis, the hospital of Vila Viçosa systematically refused the responsibility to send the insane patients to the Rilhafoles hospital in an attempt to pass this burden on the administration of the county, being very reluctant to pay the bills that came to him from the hospital of São José. The conflict between the two institutions came to the monarch with no other alternative than the payment, the hospital of village of the Alentejo region proceeded to sending parcels of money, albeit way too late. For the realization of this work we use the books of the Misericórdia and the documents of the Civil Governor found of the city of Évora under the custody of the Distrital Archive of the same city. This documents results, basically, from the correspondence between the Misericórdia of Vila Viçosa, the council administrator and the civil governor of Évora.[pt] Neste trabalho analisamos os trâmites processuais respeitantes ao envio de doentes insanos de Vila Viçosa para o hospital de Rilhafoles, na segunda metade do século XIX, e as relações estabelecidas com o hospital desta vila alentejana relativamente ao pagamento do tratamento.

    The cost-efficiency of payments for environmental services (PES) to private landowners in the Osa Conservation Area, Costa Rica, is evaluated in terms of the trade-off between biodiversity representation and opportunity costs of conservation to agricultural and forestry land-use. Using available GIS data and an 'off-the-shelf' software application called TARGET, we find that the PES allocation criteria applied by authorities in 2002-2003 were more than twice as cost-efficient as criteria applied during 1999-2001. Results show that a policy relevant assessment of the cost-effectiveness of PES relative to other conservation policies can be carried out at regional level using available studies and GIS data. However, there are a number of data and conceptual limitations to using heuristic optimisation algorithms in the analysis of the cost-efficiency of PES. Site specific data on probabilities of land-use change, and a detailed specification of opportunity costs of farm land, labour and capital are required to use algorithms such as TARGET for ranking individual sites based on cost-efficiency. Despite its conceptual soundness for regional conservation analysis, biodiversity complementarity presents a practical challenge as a criterion for PES eligibility at farm level because it varies depending on the set of areas under PES contracts at any one time.

    Full Text Available The Scarlet Macaw (Ara macao is an endangered species. In Costa Rica, the Scarlet Macaw population of the Central Pacific Conservation Area (ACOPAC, n =432 individuals has undergone considerable study and has been used effectively as a flagship species for regional conservation. Costa Rica’s only other viable Scarlet Macaw population, located in the Osa Peninsula Conservation Area (ACOSA, n=800-1200 individuals, remains virtually unstudied. We studied ACOSA Scarlet Macaw nest cavities from February 19th to March 22nd 2006. Through informal interviews with park guards and residents, we found a total of 57 potential nests in 52 trees. Eleven nests were reported as frequently poached. Scarlet Macaws used 14 identified tree species, ten of which are unrecorded in Costa Rica. The most common nesting trees were Caryocar costaricense (n=12, 24%, Schizolobium parahyba (n=9, 18.0%, Ceiba pentandra (n=7, 14.0% and Ficus sp. (n=5, 10.0%. We compare nesting characteristics to those recorded in ACOPAC. A combination of bottom-up and top-down strategies are necessary to ensure the Scarlet Macaw’s long-term success, including environmental education in local schools, community stewardship of active nests, and the advertisement of stricter penalties for poaching.

    Full Text Available Despite the importance of human taeniasis/bovine cysticercosis for public and animal health and the economy, its actual epidemiological status in Brazil is not well-studied. We sought to assess the epidemiological profile of this zoonosis in the rural area of Viçosa County, Minas Gerais, Brazil. The prevalence of bovine cysticercosis was 0.42%, whereas no case of human taeniasis was diagnosed. Factors favoring the persistence of zoonosis were identified. These included the supply of untreated water to animals, animals raised for slaughter without sanitary supervision, poor mechanization of raising techniques, and the use of untreated water for human consumption. Bovine meat for human consumption acquired in the city or from the farm itself was characterized as a risk factor for bovine cysticercosis (Odds Ratio (OR =16.77; p<0.05. Nevertheless, the families on the investigated farms did apply several appropriate measures to control this disease, such as the virtual lack of open sewers and the consumption of well-cooked meat. The presence of bovine cysticercosis cases, and the factors favoring its persistence, point to the need for constant epidemiological and sanitary surveillance in this county.

    Phytosterols are membrane components or precursors for brassinosteroid (BR) biosynthesis. As they cannot be transported long distances, their homeostasis is tightly controlled through their biosynthesis and metabolism. However, it is unknown whether microRNAs are involved in their homeostatic regulation. Rice (Oryza sativa) plants transformed with microRNA osa-miR1848 and its target, the obtusifoliol 14α-demethylase gene, OsCYP51G3, were used to investigate the role of osa-miR1848 in the regulation of phytosterol biosynthesis. osa-miR1848 directs OsCYP51G3 mRNA cleavage to regulate phytosterol and BR biosynthesis in rice. The role of OsCYP51G3 as one of the osa-miR1848 targets is supported by the opposite expression patterns of osa-miR1848 and OsCYP51G3 in transgenic rice plants, and by the identification of OsCYP51G3 mRNA cleavage sites. Increased osa-miR1848 and decreased OsCYP51G3 expression reduced phytosterol and BR concentrations, and caused typical phenotypic changes related to phytosterol and BR deficiency, including dwarf plants, erect leaves, semi-sterile pollen grains, and shorter cells. Circadian expression of osa-miR1848 regulated the diurnal abundance of OsCYP51G3 transcript in developing organs, and the response of OsCYP51G3 to salt stress. We propose that osa-miR1848 regulates OsCYP51G3 expression posttranscriptionally, and mediates phytosterol and BR biosynthesis. osa-miR1848 and OsCYP51G3 might have potential applications in rice breeding to modulate leaf angle, and the size and quality of seeds. © 2015 The Authors.

    2015-02-01

    Full Text Available The human attentional system can be subdivided into three functional networks of alerting, orienting, and executive control. Although these networks have been extensively studied in the visuospatial modality, whether the same mechanisms are deployed across different sensory modalities remains unclear. In this study we used the attention network test for visuospatial modality, in addition to two auditory variants with spatial and frequency manipulations to examine cross-modal correlations between network functions. Results showed that among the visual and auditory tasks the effects of executive control, but not effects of alerting and orienting were significantly correlated. These findings suggest that while alerting and orienting functions rely more upon modality specific processes, the executive control of attention coordinates complex behavior via supramodal mechanisms.

    Full Text Available Con el fin de caracterizar cualitativamente el perfil de metabolitos secundarios de la fracción comestible de plantas leñosas seleccionadas por vacunos en silvopastoreo, las cuales se encuentran en un bosque tropófilo semicaducifolio de Venezuela, se utilizaron 14 vacunos machos Brahman x Holstein de 390,4 ± 18,0 kg de PV. Estos fueron manejados en pastoreo continuo en una superficie de 81 ha, de las cuales 50 ha correspondían a un bosque semicaducifolio y el resto, a vegetación herbácea natural (Cynodon nlemfuensis, Sporobolus indicus, Axonopus sp., Mimosa pudica e Hyptis suaveolens. La composición de la biomasa leñosa seleccionada por los animales se estudió mediante la evaluación de los fragmentos epidérmicos presentes en las heces colectadas por vía transrectal, cada 15 días. A partir de estos resultados, se tomaron muestras de cinco plantas por especie leñosa, en los periodos seco y lluvioso. Se determinaron 15 grupos de metabolitos: alcaloides, á-aminos, carbohidratos solubles, cardenólidos, cianógenos, esteroles, fenoles totales, flavonoides, lectinas, mucílagos, quinonas, saponinas, taninos extractables (totales y condensados y terpenoides. La mayoría de la biomasa correspondió a especies de la familia Fabaceae, las cuales presentaron todos los metabolitos evaluados. En ambos periodos se detectaron niveles de esteroles, terpenoides, fenoles totales y taninos extractables que variaron desde leves hasta cuantiosos. Con independencia del periodo, el 66,7 % de las especies presentó entre 10-11 metabolitos secundarios en su biomasa comestible. Se recomienda realizar estudios para la cuantificación de los metabolitos secundarios presentes en plantas leñosas de valor forrajero, para este sistema silvopastoril

    Background: The trial to find a bedside examination that is helpful for foreseeing difficult intubation is quite inspiring. It was reported that thyromental distance (TM), body mass index (BMI), neck circumference (NC) and a Mallampati score >3 were the only helpful bedside test predictors. By using magnetic resonance imaging, it was established that more fat was present in areas around the collapsible parts of the pharynx in OSA patients.

    To investigate the factors associated with physiologic control of obstructive sleep apnea (OSA) during automatic positive airway pressure (APAP) titration in a clinical series. To also assess the usefulness of apnea-hypopnea index (AHI) data downloaded from the APAP device (Dev AHI). Retrospective review of a consecutive series of patients with OSA who underwent APAP titration (Autoset Spirit, ResMed, Bella Vista, New South Wales, Australia ) with simultaneous polysomnographic (PSG) monitoring in the sleep laboratory. Tertiary sleep clinic. There were 190 consecutive patients with OSA referred for APAP titration. There were 58% of patients who achieved optimal or good control of OSA (titration PSG AHI titration. The independent predictors of titration PSG AHI were a history of cardiac disease and elevated central apnea and arousal indices during the diagnostic study. Although the median and interquartile range (IQR) AHI from the device (7.0, 3.9-11.6 events/hr) was only slightly less than the PSG AHI (7.8, 3.9-14.4 events/hr, P = 0.04) during titration, case-by-case agreement between the two measures was poor (chi-square titration is often poor, and close clinical follow-up is particularly needed in patients with a history of cardiac disease or with high arousal or central apnea indices on the diagnostic study. Device AHI does not reliably assess control during APAP titration, and PSG assessment may be required if clinical response to treatment is poor. The findings relate to the ResMed AutoSet device and may not apply to other devices.

    Full Text Available Introduction: Little is known about the impact of spousal involvement on continuous positive airway pressure (CPAP adherence. The aim of this study was to determine whether spouse involvement affects adherence with CPAP therapy, and how this association varies with gender. Methods: 194 subjects recruited from Apnea Positive Pressure Long Term Efficacy Study (APPLES completed the Dyadic Adjustment Scale (DAS. The majority of participants were Caucasian (83%, and males (73%, with mean age of 56 years, mean BMI of 31 kg/m2. & 62% had severe OSA. The DAS is a validated 32-item self-report instrument measuring dyadic consensus, satisfaction, cohesion, and affectional expression. A high score in the DAS is indicative of a person’s adjustment to the marriage. Additionally, questions related to spouse involvement with general health and CPAP use were asked. CPAP use was downloaded from the device and self-report, and compliance was defined as usage > 4 h per night. Results: There were no significant differences in overall marital quality between the compliant and noncompliant subjects. However, level of spousal involvement was associated with increased CPAP adherence at 6 months (p=0.01. After stratifying for gender these results were significant only among males (p=0.03. Three years after completing APPLES, level of spousal involvement was not associated with CPAP compliance even after gender stratification. Conclusion: Spousal involvement is important in determining CPAP compliance in males in the 1st 6 months after initiation of therapy but is not predictive of longer-term adherence. Involvement of the spouse should be considered an integral part of CPAP initiation procedures.

  8. Mapping Tropical Forest Mosaics with C- and L-band SAR: First Results from Osa Peninsula, Costa Rica

    In tropical countries, economic incentives and improved infrastructure are creating forest mosaics where small-scale farming and industrial plantations are embedded within and potentially replacing native ecosystems. Practices such as agroforestry, slash-and-burn cultivation, and oil palm monocultures bring widely different impacts on carbon stocks. Characterizing these production systems is not only critical to ascribe deforestation to particular drivers, but also essential to understand the impact of macroeconomic scenarios, national policies, and land tenure schemes on carbon fluxes. The last decade has experienced a dramatic improvement in the extent and consistency of tree cover and gross deforestation products from optical imagery. At the same time, recent work shows that Synthetic Aperture Radar (SAR) can complement optical data and reveal structural types that cannot be easily resolved with reflectance measurements alone. While these results demonstrate the validity of sensor fusion methodologies, they typically rely on local classifications or even manual delineation and as such they cannot support large-scale investigations. Furthermore, there have been few attempts to exploit PolInSAR or multiple wavelengths that can provide critical information to resolve natural and anthropogenic land cover types. We report results from our research at Costa Rica's Osa Peninsula. This site is ideal for algorithm development as it includes a highly diverse tropical forest within Corcovado National Park, as well as agroforestry zones, mangroves, and palm plantations. We first integrate SAR backscatter and coherence data from NASA's L-band UAVSAR, JAXA's ALOS/PALSAR, and ESA's Sentinel to produce a map of structural types. Second, we assess whether coherence measurements and PolInSAR retrievals can be used to resolve forest stand differences at 30m resolution and disitinguish between primary and secondary forest sites.

    Long-term continuous positive airway pressure (CPAP) usage varies between individuals. It would be of value to be able to identify those who are likely to benefit from CPAP (and use it long term), versus those who would not, and might therefore benefit from additional help early on. First, we explored whether baseline characteristics predicted CPAP usage in minimally symptomatic obstructive sleep apnoea (OSA) patients, a group who would be expected to have low usage. Second, we explored if early CPAP usage was predictive of longer-term usage, as has been shown in more symptomatic OSA patients. The MOSAIC trial was a multi-centre randomised controlled trial where minimally symptomatic OSA patients were randomised to CPAP, or standard care, for 6 months. Here we have studied only those patients randomised to CPAP treatment. Baseline characteristics including symptoms, questionnaires [including the Epworth sleepiness score (ESS)] and sleep study parameters were recorded. CPAP usage was recorded at 2-4 weeks after initiation and after 6 months. The correlation and association between baseline characteristics and 6 months CPAP usage was assessed, as was the correlation between 2 and 4 weeks CPAP usage and 6 months CPAP usage. One hundred and ninety-five patients randomised to CPAP therapy had median [interquartile range (IQR)] CPAP usage of 2:49 (0:44, 5:13) h:min/night (h/n) at the 2-4 weeks visit, and 2:17 (0:08, 4:54) h/n at the 6 months follow-up visit. Only male gender was associated with increased long-term CPAP use (male usage 2:56 h/n, female 1:57 h/n; P=0.02). There was a moderate correlation between the usage of CPAP at 2-4 weeks and 6 months, with about 50% of the variability in long-term use being predicted by the short-term use. In patients with minimally symptomatic OSA, our study has shown that male gender (and not OSA severity or symptom burden) is associated with increased long-term use of CPAP at 6 months. Although, in general, early patterns of CPAP

  14. Executive Information Systems' Multidimensional Models

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available Executive Information Systems are design to improve the quality of strategic level of management in organization through a new type of technology and several techniques for extracting, transforming, processing, integrating and presenting data in such a way that the organizational knowledge filters can easily associate with this data and turn it into information for the organization. These technologies are known as Business Intelligence Tools. But in order to build analytic reports for Executive Information Systems (EIS in an organization we need to design a multidimensional model based on the business model from the organization. This paper presents some multidimensional models that can be used in EIS development and propose a new model that is suitable for strategic business requests.

Performance incentives derived from the model are compared with the performance incentives of 350 firms chosen from a survey by Michael Jensen and Kevin Murphy. The results suggest both that the model does a reasonable job of explaining the data and that actual incentives are close to the optimal incentives predicted by theory.

    The Neutron Science Portal at Oak Ridge National Laboratory submits jobs to the TeraGrid for remote job execution. The TeraGrid is a network of high performance computers supported by the US National Science Foundation. There are eleven partner facilities with over a petaflop of peak computing performance and sixty petabytes of long-term storage. Globus is installed on a local machine and used for job submission. The graphical user interface is produced by java coding that reads an XML file. After submission, the status of the job is displayed in a Job Information Service window which queries globus for the status. The output folder produced in the scratch directory of the TeraGrid machine is returned to the portal with globus-url-copy command that uses the gridftp servers on the TeraGrid machines. This folder is copied from the stage-in directory of the community account to the user's results directory where the output can be plotted using the portal's visualization services. The primary problem with remote job execution is diagnosing execution problems. We have daily tests of submitting multiple remote jobs from the portal. When these jobs fail on a computer, it is difficult to diagnose the problem from the globus output. Successes and problems will be presented

  1. [Memory and the executive functions].

    Science.gov (United States)

    Tirapu-Ustárroz, J; Muñoz-Céspedes, J M

    The terms 'executive functioning' or 'executive control' refer to a set of mechanisms involved in the improvement of cognitive processes to guide them towards the resolution of complex problems. Both the frontal lobes, acting as structure, and the executive processes, acting as function, work with memory contents, operating with information placed in the diencephalic structures and in the medial temporal lobe. Generally, we can state that many works find an association between frontal damage and specific memory shortages like working memory deficit, metamemory problems, source amnesia, or difficulties in the prospective memory. This paper is a critical review of the working memory concept and proposes a new term: the attentional operative system that works with memory contents. Concerning the metamemory, the frontal lobes are essential for monitoring processes in general and for 'the feeling of knowing' kind of judgements in particular. Patients suffering prefrontal damage show serious problems to remember the information source. Thus, the information is rightly remembered but the spatiotemporal context where that information was learned has been forgotten. Finally, the prospective memory deals with remembering to make something in a particular moment in the future and performing the plan previously drawn up.

    Fernandes-Silva, A. A.

    2013-03-01

    Full Text Available The aim of this study was to assess the effect of different irrigation strategies on the sensory quality of virgin olive oil (VOO from the cv. “cobrançosa” integrated into a protected denomination of origin of “Azeite de Trás-os-Montes” in the Northeast of Portugal. Three irrigation treatments were applied: (T2-full irrigation, which received a seasonal water equivalent of 100% of the estimated crop evapotranspiration (ETc, (T1-continuous deficit irrigation (30% ETc and (T0- rainfed treatment. Data were collected from two consecutive crop years (2005-2006. Olive oil samples were analyzed for volatiles by GC-MS and the results compared with sensory evaluation data. Total volatile compounds tended to decrease with the amount of water applied. The characteristics pungent and bitter were more pronounced in olive oils from T0 and T1, which had higher polyphenolic concentrations, with a strong positive relationship with this variable and the bitter attribute. The Principal Components Analysis clearly separates the three olive oils from 2005, the driest year, and aggregates into a single group the three samples from 2006, suggesting no effect of irrigation on volatile compounds in years with a rainy spring and a marked effect in years with severe drought, suggesting that the effect of the trees’ water status on these variables occurs throughout the crop season and not just during the oil accumulation phase. In general, olive oil from the cv. Cobrançosa is more bitter than pungent and has a typical nutty sensory attribute shown by a strong positive relationship between benzaldehyde and the sensory notes of almonds and nuts.

    To analyze the reliability and validity of the Spanish version of the OSA-18 quality of life questionnaire in children with apnea-hypopnea syndrome (SAHS). Children with suspected SAHS were studied with polysomnography (PSG) before and after adenotonsillectomy (AA). Age, gender, clinical data, PSG, anthropometric data, and Mallampati and Brodsky scales were analyzed. OSA-18 was administered at baseline and 3-6months post AA. After translation and backtranslation by bilingual professionals, the internal consistency, reliability, construct validity, concurrent validity, predictive validity and sensitivity to change of the questionnaire was assessed. In total, 45 boys and 15 girls were evaluated, showing BMI 18±4, neck 28±5, Brodsky (0: 7%; 50 to 75%: 6%), AHI 12±7 pre AA. Global Cronbach alpha was 0.91. Correlations between domains were significant except for emotional aspects, although the total scores correlated with all domains (0.50 to 0.90). The factorial analysis was virtually identical to the original structure. The total scores showed good correlation for concurrent validity (0.2-0.45). With regard to predictive validity, the questionnaire adequately differentiated levels of severity according to Mallampati (ANOVA P=.002) and apnea-hypopnea index (ANOVA P=.006). Test-retest reliability was excellent, as was sensitivity to change, both in the total scores (P<.001) and in each domain (P<.001). The Spanish adaptation of the OSA-18 and its psychometric characteristics suggest that the Spanish version is equivalent to the original and can be used in Spanish-speaking countries.

Cet article constitue un essai d’interprétation de deux versions quechuas cuzquéniennes du récit panandin connu comme “Jean de l’Ours” ou “Le fils de l’ours”. A partir d’une analyse du symbolisme du récit, la logique profonde qui l’ordonne est mise en lumière: la société humaine et civilisée ne peut se perpétuer sans établir des échanges et une coopération avec les êtres sauvages de l’au-delà. Les protagonistes, fils d’un curé et d’une ourse, ainsi que le curé lui-même, sont les héros médiateurs d’un récit mythique dont la logique prétend aussi s’appliquer aux relations interethniques dans les Andes. Este artículo presenta un ensayo de interpretación de dos versiones quechuas cuzqueñas del relato panandino conocido como “Juan Oso” o “El hijo del oso”. A partir de un análisis del simbolismo del relato, se saca a luz la lógica profunda que lo ordena: la sociedad humana y civilizada no puede perpetuarse sin establecer un intercambio y una cooperación con los seres salvajes del más allá. Los protagonistas, hijos de un cura y una osa, así como el cura mismo, son los héroes mediadores de un relato mítico cuya lógica pretende también aplicarse a las relaciones interétnicas en los Andes. THE PRIEST AND HIS BEAR CHILDREN OR THE PASSAGE TO CIVILIZATION OF THE CHILDREN OF A PRIEST AND A SHE-BEAR. This article sets out to interpret two Cuzco Quechua versions of the pan-Andean tale known as “Juan Oso” or “The Bear’s Son”. The analysis of the story’s symbolism sheds light on the profound logic on which it is based: human and civilized society cannot survive without establishing interchange and cooperation with wild beings from the other world. The protagonist, the son of the priest and the she-bear, as well as the priest himself, are the mediator heroes of a tale whose logic also applies to interethnic

    2001-02-01

    This research examines the job and career changes of healthcare executives and managers working in different segments of the healthcare industry in the western United States. The results suggest that the job and career patterns in the healthcare delivery sector are undergoing significant transformation. One third of the respondents reports that at least one of their last four job changes was involuntary or unplanned. One half of those attempted to make a career change. This study identifies four different executive and management career patterns. The most common was one of multiple career changes. The second pattern was that of a single career change, followed by a 'traditional' career in which one did not seek a career change. The final pattern was characterized as a movement back and forth between two different segments of the healthcare industry. Age, gender, marital status and education were not associated with any specific career pattern. The need to achieve results early in the respondent's career had a strong influence on career patterns. This study confirms the fluidity of career movement and the changing permeability between the various segments of the healthcare industry. It also suggests that career success increasingly will require broad management experience in those different segments.

    Full Text Available The present study was aimed at investigating different aspects of Executive Functions (EF in children with Developmental Dyslexia (DD.A neuropsychological battery tapping verbal fluency, spoonerism, attention, verbal shifting, short-term and working memory was used to assess 60 children with DD and 65 with typical reading abilities.Compared to their controls, children with DD showed deficits in several EF domains such as verbal categorical and phonological fluency, visual-spatial and auditory attention, spoonerism, verbal and visual short-term memory, and verbal working memory. Moreover, exploring predictive relationships between EF measures and reading, we found that spoonerism abilities better explained word and non-word reading deficits. Although to a lesser extent, auditory and visual-spatial attention also explained the increased percentage of variance related to reading deficit.EF deficits found in DD are interpreted as an expression of a deficient functioning of the Central Executive System and are discussed in the context of the recent temporal sampling theory.

    Full Text Available During 2009, the Haifa district of Clalit Health Services (CHS has switched from in-lab polysomnography (PSG to home studies for the diagnosis of obstructive sleep apnea (OSA. We assessed the effects of this change on accessibility, waiting time, satisfaction, costs, and CPAP purchase by the patients. Data regarding sleep studies, CPAP purchase, and waiting times were collected retrospectively from the computerized database of CHS. Patients’ satisfaction was assessed utilizing a telephone questionnaire introduced to a randomized small sample of 70 patients. Comparisons were made between 2007 and 2008 (in-lab PSGs and 2010 and 2011 (when most studies were ambulatory. Of about 650000 insured individuals in the Haifa district of CHS, 1471 sleep studies were performed during 2007-2008 compared to 2794 tests during 2010-2011. The average waiting time was 9.9 weeks in 2007-2008 compared to 1.1 weeks in 2010-2011 (P<0.05. 597 CPAPs were purchased in 2007-2008 compared to 831 in 2010-2011. The overall patients’ satisfaction was similar, but discomfort tended to be higher in the in-laboratory group (4.1 vs 2.7 in a scale of 0–10; P=0.11. Switching to ambulatory diagnosis improved the test accessibility and reduced the waiting times. Patients’ satisfaction remained similarly high. The total direct cost of OSA management was reduced.

    We examined the relationship between health care expenditures and cognition, focusing on differences across cognitive systems defined by global cognition, executive function, or episodic memory. We used linear regression models to compare annual health expenditures by cognitive status in 8125 Nurses' Health Study participants who completed a cognitive battery and were enrolled in Medicare parts A and B. Adjusting for demographics and comorbidity, executive impairment was associated with higher total annual expenditures of $1488 per person (P episodic memory impairment was found. Expenditures exhibited a linear relationship with executive function, but not episodic memory ($584 higher for every 1 standard deviation decrement in executive function; P < .01). Impairment in executive function is specifically and linearly associated with higher health care expenditures. Focusing on management strategies that address early losses in executive function may be effective in reducing costly services. Copyright © 2017 the Alzheimer's Association.

    Executable Architectures allow the evaluation of system architectures not only regarding their static, but also their dynamic behavior. However, the systems engineering community do not agree on a common formal specification of executable architectures. To close this gap and identify necessary elements of an executable architecture, a modeling language, and a modeling formalism is topic of ongoing PhD research. In addition, systems are generally defined and applied in an operational context to provide capabilities and enable missions. To maximize the benefits of executable architectures, a second PhD effort introduces the idea of creating an executable context in addition to the executable architecture. The results move the validation of architectures from the current information domain into the knowledge domain and improve the reliability of such validation efforts. The paper presents research and results of both doctoral research efforts and puts them into a common context of state-of-the-art of systems engineering methods supporting more agility.

    2000-01-01

    The "s" word can now be spoken without flinching in health care organizations. Spirituality is becoming a common topic in management conferences around the world. Many U.S. corporations are recognizing the role of spirituality in creating a new humanistic capitalism that manages beyond the bottom line. Spirituality refers to a broad set of principles that transcend all religions. It is the relationship between yourself and something larger, such as the good of your patient or the welfare of the community. Spirituality means being in right relationship to all that is and understanding the mutual interdependence of all living beings. Physician executives should be primary proponents of spirituality in their organizations by: Modeling the power of spirituality in their own lives; integrating spiritual methodologies into clinical practice; fostering an integrative approach to patient care; encouraging the organization to tithe its profits for unmet community health needs; supporting collaborative efforts to improve the health of the community; and creating healing environments.

  10. A simple hypothesis of executive function

    2012-06-01

    Full Text Available Executive function is traditionally conceptualized as a set of abilities required to guide behavior toward goals. Here, an integrated theoretical framework for executive function is developed which has its roots in the notion of hierarchical mental models. Further following Duncan (2010a,b, executive function is construed as a hierarchical recursive system of test-operation-test-exit units (Miller, Galanter, and Pribram, 1960. Importantly, it is shown that this framework can be used to model the main regional prefrontal syndromes, which are characterized by apathetic, disinhibited and dysexecutive cognition and behavior, respectively. Implications of these considerations for the neuropsychological assessment of executive function are discussed.

    Pilots are constantly exposed to a number of environmental factors, which include +Gz load. Physiological changes evoked by +Gz stimuli have already been well investigated in aviation medicine. However, the influence of +Gz stimulation on executive functions in pilots has not yet been thoroughly explored. There were 20 pilot cadets between the ages of 19 and 22 yr who volunteered to participate in the experiment. The subjects were divided into two groups: the G-load group, which was exposed to accelerations in the centrifuge, and the control group, which did not undergo this stimulation. Executive functions were assessed by means of the Schulte tables and the Rey-Osterrieth complex figure test. +Gz load exposure significantly improved attention switching. This relationship was valid for performance speed (M = 268.09 s in the pretest in the G-load group; M = 228.09 s in the posttest in the G-load group) and for the cumulative time of mistakes (M = 26.73 s in the pretest in the G-load group; M = 12 s in the posttest in the G-load group), whereas reproduction of visuospatial stimuli from memory deteriorated significantly under the influence of +Gz stimulation (M = 17.18 points in the posttest in the G-load group; M = 28.18 points in the posttest in the control group). These results suggest that the impact of +Gz load is not homogenous and unidirectional, since it improves attention switching but visuospatial working memory decreases under its influence. These aspects are particularly important for understanding the mechanisms responsible for maintaining situational awareness during the flight.

Seleccionamos como especies típicas de borde las que tenían mayor abundancia en esta zona, presentes en ambos parches del borde y capaces de colonizar la matriz adyacente. Se obtuvo un conjunto de nueve especies a las cuales se les evaluaron 20 atributos vitales, generando seis grupos mediante un análisis de agrupamiento (cluster: 1 Weinmannia balbisiana-W. tomentosa, 2 Gaiadendron punctatum-Hedyosmum bonplandianum, 3 Miconia ligustrina-M. squamulosa, 4 Macleania rupestris, 5 Pentacalia pulchella y 6 Tibouchina grossa. La amplia variación y plasticidad de las especies estudiadas en cuanto a los atributos analizados, conduce a pensar que los conjuntos obtenidos no obedecen a grupos funcionales claramente diferenciados, sino más bien a estrategias diferentes y que estas especies podrían hacer parte de un solo grupo funcional de gran plasticidad. T. grossa es la especie de borde más exitosa en la reserva, dados sus altos valores de abundancia, tolerancia fisiológica, reproducción vegetativa, producción de hojarasca y producción de semillas pequeñas, numerosas, formadoras de un banco de semillas persistente que evidencian su alta fecundidad.Vital traits of woody species in High Andean forest edges of the Cogua Forest Reserve (Colombia.

    Minimally symptomatic obstructive sleep apnea (OSA) is highly prevalent, and the effects of continuous positive airway pressure (CPAP) on myocardial function in these patients are unknown. The MOSAIC randomized, controlled trial of CPAP for minimally symptomatic OSA assessed the effect of CPAP on myocardial function in a subset of patients. Two centers taking part in the MOSAIC trial randomized 238 patients in parallel to 6 months of CPAP (120) or standard care (118). Of these, 168 patients had echocardiograms, and 68 patients had a cardiac magnetic resonance scan (CMR). A larger group (314) from 4 centers had brain natriuretic peptide (BNP) measured. Mean (SD) baseline oxygen desaturation index (ODI) and Epworth sleepiness score (ESS) were 13.5 (13.2), and 8.4 (4.0), respectively. CPAP significantly reduced ESS and ODI. Baseline LV ejection fraction (LVEF) was well preserved (60.4%). CPAP had no significant effect on echo-derived left atrial (LA) area (-1.0 cm2, 95% CI -2.6 to +0.6, p = 0.23) or early to late left ventricular filling velocity (E/A) ratio (-0.01, 95% CI -0.07 to +0.05, p = 0.79). There was a small change in echo-derived LV end diastolic volume (EDV) with CPAP (-5.9 mL, 95% CI -10.6 to -1.2, p = 0.015). No significant changes were detected by CMR on LV mass index (+1.1 g/m(2), 95% CI -5.9 to +8.0, p = 0.76) or LVEF (+0.8%, 95% CI -1.2 to +2.8, p = 0.41). CPAP did not affect BNP levels (p = 0.16). Six months of CPAP therapy does not change cardiac functional or structural parameters measured by echocardiogram or CMR in patients with minimally symptomatic mild-to-moderate OSA.

    1996-12-31

    Brain executive function is based in a distributed system whereby prefrontal cortex is interconnected with other cortical. and subcortical loci. Executive function is divided roughly into three interacting parts: affective guidance of responses; linkage among working memory representations; and forming complex behavioral schemata. Neural network models of each of these parts are reviewed and fit into a preliminary theoretical framework.

    Earliest notions concerning autism (Autism Spectrum Disorders, ASD) describe the disturbance in executive functioning. Despite altered definition, executive functioning, expressed as higher cognitive skills required complex behaviors linked to the prefrontal cortex, are defective in autism. Specific difficulties in children presenting autism or verbal disabilities at executive functioning levels have been identified. Nevertheless, the developmental deficit of executive functioning in autism is highly diversified with huge individual variation and may even be absent. The aim of the present study to examine the current standing of intact executive functioning intact in ASD. Analysis of ASD populations, whether high-functioning, Asperger's or autism Broad Phenotype, studied over a range of executive functions including response inhibition, planning, cognitive flexibility, cognitive inhibition, and alerting networks indicates an absence of damage/impairment compared to the typically-developed normal control subjects. These findings of intact executive functioning in ASD subjects provide a strong foundation on which to construct applications for growth environments and the rehabilitation of autistic subjects.

  10. A pilot study to compare the cerebral hemodynamics between patients with obstructive sleep apnea syndrome (OSA) and periodic limb movement syndrome (PLMS) during nocturnal sleep with near-infrared spectroscopy (NIRS)

    Obstructive sleep apnea syndrome (OSA) and periodic limb movement in sleep syndrome (PLMS) are two common sleep disorders. Previous studies showed that OSA and PLMS share common features, such as increased cardio-vascular risk, both apnea events and limb movements occur periodically, they are usually associated with cortical arousals, and both of them can induce declines in peripheral oxygen saturation measured with pulse oximetry. However, the question whether apnea events and limb movements also show similar characteristics in cerebral hemodynamic and oxygenation has never been addressed. In this pilot study, we will first time compare the cerebral hemodynamic changes induced by apnea events and limb movements in patients with OSA (n=4) and PLMS (n=4) with NIRS. In patients with OSA, we found periodic oscillations in HbO2, HHb, and blood volume induced by apnea/hypopnea events, HbO2 and HHb showed reverse changing trends. By contrast, the periodic oscillations linked to limb movements were only found in HbO2 and blood volume in patients with PLMS. These findings of different cerebral hemodynamics patterns between apnea events and limb movements may indicate different regulations of nervous system between these two sleep disorders.

    A faithful execution system includes system memory, a target processor, and protection engine. The system memory stores a ciphertext including value fields and integrity fields. The value fields each include an encrypted executable instruction and the integrity fields each include an encrypted integrity value for determining whether a corresponding one of the value fields has been modified. The target processor executes plaintext instructions decoded from the ciphertext while the protection engine is coupled between the system memory and the target processor. The protection engine includes logic to retrieve the ciphertext from the system memory, decrypt the value fields into the plaintext instructions, perform an integrity check based on the integrity fields to determine whether any of the corresponding value fields have been modified, and provide the plaintext instructions to the target processor for execution.

    Burke, G C; Bice, M O

    1991-01-01

    Health care executives must consider renewal and change within their own lives if they are to breathe life into their own institutions. Yet numerous barriers to executive renewal exist, including time pressures, fatigue, cultural factors, and trustee attitudes. This essay discusses such barriers and suggests approaches that health care executives may consider for programming renewal into their careers. These include self-assessment for professional and personal goals, career or job change, process vs. outcome considerations, solitude, networking, lifelong education, surrounding oneself with change agents, business travel and sabbaticals, reading outside the field, physical exercise, mentoring, learning from failures, a sense of humor, spiritual reflection, and family and friends. Renewal is a continuous, lifelong process requiring constant learning. Individual executives would do well to develop a framework for renewal in their careers and organizations.

We examine the location and relational dependence of the network contact. Our results reveal that executives are more likely to perceive...... insiders in their network to be helpful, but geographic location has no effect on expectations of receiving help. With regards to relational dependence: executives who are more dependent on their contacts are more likely to perceive them to be helpful. We also look at whether perceived helpfulness affects...... an executive’s willingness to engage in risky new business development -- an important performance indicator - and indeed find that those executives that perceive their networks to be helpful are more likely to be willing to take risky decisions.

  18. Executive dysfunction, brain aging, and political leadership.

    Science.gov (United States)

    Fisher, Mark; Franklin, David L; Post, Jerrold M

    2014-01-01

    Decision-making is an essential component of executive function, and a critical skill of political leadership. Neuroanatomic localization studies have established the prefrontal cortex as the critical brain site for executive function. In addition to the prefrontal cortex, white matter tracts as well as subcortical brain structures are crucial for optimal executive function. Executive function shows a significant decline beginning at age 60, and this is associated with age-related atrophy of prefrontal cortex, cerebral white matter disease, and cerebral microbleeds. Notably, age-related decline in executive function appears to be a relatively selective cognitive deterioration, generally sparing language and memory function. While an individual may appear to be functioning normally with regard to relatively obvious cognitive functions such as language and memory, that same individual may lack the capacity to integrate these cognitive functions to achieve normal decision-making. From a historical perspective, global decline in cognitive function of political leaders has been alternatively described as a catastrophic event, a slowly progressive deterioration, or a relatively episodic phenomenon. Selective loss of executive function in political leaders is less appreciated, but increased utilization of highly sensitive brain imaging techniques will likely bring greater appreciation to this phenomenon. Former Israeli Prime Minister Ariel Sharon was an example of a political leader with a well-described neurodegenerative condition (cerebral amyloid angiopathy) that creates a neuropathological substrate for executive dysfunction. Based on the known neuroanatomical and neuropathological changes that occur with aging, we should probably assume that a significant proportion of political leaders over the age of 65 have impairment of executive function.

  19. Executive Functioning Heterogeneity in Pediatric ADHD.

    Kofler, Michael J; Irwin, Lauren N; Soto, Elia F; Groves, Nicole B; Harmon, Sherelle L; Sarver, Dustin E

    2018-04-28

    Neurocognitive heterogeneity is increasingly recognized as a valid phenomenon in ADHD, with most estimates suggesting that executive dysfunction is present in only about 33%-50% of these children. However, recent critiques question the veracity of these estimates because our understanding of executive functioning in ADHD is based, in large part, on data from single tasks developed to detect gross neurological impairment rather than the specific executive processes hypothesized to underlie the ADHD phenotype. The current study is the first to comprehensively assess heterogeneity in all three primary executive functions in ADHD using a criterion battery that includes multiple tests per construct (working memory, inhibitory control, set shifting). Children ages 8-13 (M = 10.37, SD = 1.39) with and without ADHD (N = 136; 64 girls; 62% Caucasian/Non-Hispanic) completed a counterbalanced series of executive function tests. Accounting for task unreliability, results indicated significantly improved sensitivity and specificity relative to prior estimates, with 89% of children with ADHD demonstrating objectively-defined impairment on at least one executive function (62% impaired working memory, 27% impaired inhibitory control, 38% impaired set shifting; 54% impaired on one executive function, 35% impaired on two or all three executive functions). Children with working memory deficits showed higher parent- and teacher-reported ADHD inattentive and hyperactive/impulsive symptoms (BF 10  = 5.23 × 10 4 ), and were slightly younger (BF 10  = 11.35) than children without working memory deficits. Children with vs. without set shifting or inhibitory control deficits did not differ on ADHD symptoms, age, gender, IQ, SES, or medication status. Taken together, these findings confirm that ADHD is characterized by neurocognitive heterogeneity, while suggesting that contemporary, cognitively-informed criteria may provide improved precision for identifying a

  1. Quality circles: the nurse executive as mentor.

    Science.gov (United States)

    Flarey, D L

    1991-12-01

    Changes within and around the health care environment are forcing health care executives to reexamine their managerial and leadership styles to confront the resulting turbulence. The nurse executive is charged with the profound responsibility of directing the delivery of nursing care throughout the organization. Care delivered today must be of high quality. Declining financial resources as well as personnel shortages cause the executive to be an effective innovator in meeting the increasing demands. Quality circles offer the nurse executive an avenue of recourse. Circles have been effectively implemented in the health care setting, as has been consistently documented over time. By way of a participative management approach, quality circles may lead to increased employee morale and productivity, cost savings, and decreased employee turnover rates, as well as realization of socialization and self-actualization needs. A most effective approach to their introduction would be implementation at the first-line manager level. This promotes an acceptance of the concept at the management level as well as a training course for managers to implement the process at the unit level. The nurse executive facilitates the process at the first-line manager level. This facilitation will cause a positive outcome to diffuse throughout the entire organization. Quality circles offer the nurse executive the opportunity to challenge the existing environmental turmoil and effect a positive and lasting change.

  2. Metacognition and executive functioning in Elementary School

    Directory of Open Access Journals (Sweden)

    Trinidad García

    Full Text Available This study analyzes differences in metacognitive skills and executive functioning between two groups of students (10-12 years with different levels of metacognitive knowledge (high n = 50, low n = 64. Groups were established based on students' score on a test of knowledge of strategy use. Metacognitive skills were assessed by means of self-report. Students reported the frequency with which they applied these strategies during the phases of planning, execution, and evaluation of learning. Information about student executive functioning was provided by families and teachers, who completed two parallel forms of a behavior rating scale. The results indicated that: a the group with high levels of metacognitive knowledge reported using their metacognitive skills more frequently than their peers in the other group. These differences were statistically significant in the phases of planning and execution; b both family and teachers informed of better levels of executive functioning in the students with high metacognitive knowledge. Statistically significant differences were found in planning, functional memory, focus, and sustained attention. These results show the existence of an association between different levels of metacognitive knowledge, and differences in metacognitive skills and executive functions, and suggest the need to emphasize this set of variables in order to encourage students to acquire increasing levels of control over their learning process.

  3. Statistical Symbolic Execution with Informed Sampling

    Science.gov (United States)

    Filieri, Antonio; Pasareanu, Corina S.; Visser, Willem; Geldenhuys, Jaco

    2014-01-01

    Symbolic execution techniques have been proposed recently for the probabilistic analysis of programs. These techniques seek to quantify the likelihood of reaching program events of interest, e.g., assert violations. They have many promising applications but have scalability issues due to high computational demand. To address this challenge, we propose a statistical symbolic execution technique that performs Monte Carlo sampling of the symbolic program paths and uses the obtained information for Bayesian estimation and hypothesis testing with respect to the probability of reaching the target events. To speed up the convergence of the statistical analysis, we propose Informed Sampling, an iterative symbolic execution that first explores the paths that have high statistical significance, prunes them from the state space and guides the execution towards less likely paths. The technique combines Bayesian estimation with a partial exact analysis for the pruned paths leading to provably improved convergence of the statistical analysis. We have implemented statistical symbolic execution with in- formed sampling in the Symbolic PathFinder tool. We show experimentally that the informed sampling obtains more precise results and converges faster than a purely statistical analysis and may also be more efficient than an exact symbolic analysis. When the latter does not terminate symbolic execution with informed sampling can give meaningful results under the same time and memory limits.

To develop pretherapy and in-therapy scores to predict adherence pattern. Methods: Newly diagnosed adult OSAS patients were consecutively recruited from March to August 2013. Baseline clinical information and measures such as Epworth Sleepiness Scale (ESS, Fatigue Severity Scale (FSS, Zung’s Self-Rating Depression Scale (SDS, and The Pittsburgh Sleep Quality Index (PSQI at baseline and at the end of 3rd-week therapy were collected. Twelve weeks’ adherence data were collected from the nCPAP memory card, and K-means cluster analysis was used to explore adherence patterns. Predictive scores were developed from the coefficients of cumulative logit models of adherence patterns using variables available at baseline and after 3 weeks of therapy. Performance of the score was validated using 500 bootstrap resamples. Results: Seventy six patients completed a 12-week follow-up. Three patterns were revealed. Patients were identified as developing an adherence pattern that was poor (n=14, mean ± SD, 2.3±0.9 hours per night, moderate (n=19, 5.3±0.6 hours per night, or good (n=43, 6.8±0.3 hours per night.

    Background Post-stroke Depression, Obstructive sleep apnea (OSA) and Cognitive impairment (“DOC”) are associated with greater mortality, worse recovery and poorer quality of life. Best practice recommendations endorse routine screening for each condition; yet, all are under-assessed, diagnosed and treated. We seek to determine the feasibility and validity of an integrated tool (“DOC” screen) to identify stroke clinic patients at high-risk of depression, OSA, and cognitive impairment. Methods All consecutive new referrals to a regional Stroke Prevention Clinic who were English-speaking and non-aphasic were eligible to be screened. Time for screen completion was logged. DOC screen results were compared to the neuropsychological battery and polysomnogram assessments using a modified receiver operator characteristic and area under the curve analysis. Data is reported to conform to STARD guidelines. Findings 1503 people were screened over 2 years. 89% of eligible patients completed the screen in 5 minutes or less (mean 4.2 minutes), less than half the time it takes to complete the Montreal Cognitive Assessment (MoCA). 437 people consented to detailed testing. Of those, 421 completed the Structured Clinical Interview for Depression within 3 months of screening, 387 completed detailed neuropsychological testing within 3 months, and 88 had overnight polysomnograms. Screening scores combined with demographic variables (age, sex, education, body mass index), had excellent validity compared to gold standard diagnoses: DOC-Mood AUC 0.90; DOC-Apnea AUC 0.80; DOC-Cog AUC 0.81. DOC screen scores can reliably categorize patients in to low-, intermediate- or high-risk groups for further action and can do so with comparable accuracy to more time-consuming screens. Conclusions Systematic screening of depression, obstructive sleep apnea, and cognitive impairment in 5 minutes or less is feasible and valid in a high volume stroke clinic using the DOC screen. The DOC screen may

Assim, inventariaram-se todas as árvores com DAP igual ou superior a 5 cm presentes na Universidade. Para as árvores não palmeiras, selecionaram-se 721 árvores-amostra, que foram cubadas rigorosamente em pé através da aplicação sucessiva da expressão de Smalian até o diâmetro-limite de 5 cm, tanto para o fuste quanto para os galhos. No caso das palmeiras, cubaram-se 100% dos indivíduos utilizando a expressão de Huber. A densidade básica da madeira com casca e o teor de carbono foram obtidos, nas palmeiras, com a retirada de um disco na porção do DAP, dada a dificuldade de tradagem. Já nas demais árvores, utilizou-se um trado mecânico. Com base no volume, na densidade básica e no teor de carbono, calcularam-se o carbono total e o carbono dos galhos. Ademais, avaliaram-se os modelos de Schumacher e Hall (1933 e Spurr (1952, modificado para estimar o carbono fixado nesses indivíduos.

  7. Toward synthesizing executable models in biology.

    Over the last decade, executable models of biological behaviors have repeatedly provided new scientific discoveries, uncovered novel insights, and directed new experimental avenues. These models are computer programs whose execution mechanistically simulates aspects of the cell's behaviors. If the observed behavior of the program agrees with the observed biological behavior, then the program explains the phenomena. This approach has proven beneficial for gaining new biological insights and directing new experimental avenues. One advantage of this approach is that techniques for analysis of computer programs can be applied to the analysis of executable models. For example, one can confirm that a model agrees with experiments for all possible executions of the model (corresponding to all environmental conditions), even if there are a huge number of executions. Various formal methods have been adapted for this context, for example, model checking or symbolic analysis of state spaces. To avoid manual construction of executable models, one can apply synthesis, a method to produce programs automatically from high-level specifications. In the context of biological modeling, synthesis would correspond to extracting executable models from experimental data. We survey recent results about the usage of the techniques underlying synthesis of computer programs for the inference of biological models from experimental data. We describe synthesis of biological models from curated mutation experiment data, inferring network connectivity models from phosphoproteomic data, and synthesis of Boolean networks from gene expression data. While much work has been done on automated analysis of similar datasets using machine learning and artificial intelligence, using synthesis techniques provides new opportunities such as efficient computation of disambiguating experiments, as well as the ability to produce different kinds of models automatically from biological data.

    Sophie Bayard

    Full Text Available BACKGROUND: Narcolepsy with cataplexy (NC is a disabling sleep disorder characterized by early loss of hypocretin neurons that project to areas involved in the attention network. We characterized the executive control of attention in drug-free patients with NC to determine whether the executive deficits observed in patients with NC are specific to the disease itself or whether they reflect performance changes due to the severity of excessive daytime sleepiness. METHODOLOGY: Twenty-two patients with NC compared to 22 patients with narcolepsy without cataplexy (NwC matched for age, gender, intellectual level, objective daytime sleepiness and number of sleep onset REM periods (SOREMPs were studied. Thirty-two matched healthy controls were included. All participants underwent a standardized interview, completed questionnaires, and neuropsychological tests. All patients underwent a polysomnography followed by multiple sleep latency tests (MSLT, with neuropsychological evaluation performed the same day between MSLT sessions. PRINCIPAL FINDINGS: Irrespective of diagnosis, patients reported higher self-reported attentional complaints associated with the intensity of depressive symptoms. Patients with NC performed slower and more variably on simple reaction time tasks than patients with NwC, who did not differ from controls. Patients with NC and NwC generally performed slower, reacted more variably, and made more errors than controls on executive functioning tests. Individual profile analyses showed a clear heterogeneity of the severity of executive deficit. This severity was related to objective sleepiness, higher number of SOREMPs on the MSLT, and lower intelligence quotient. The nature and severity of the executive deficits were unrelated to NC and NwC diagnosis. CONCLUSIONS: We demonstrated that drug-free patients with NC and NwC complained of attention deficit, with altered executive control of attention being explained by the severity of objective

    The floristic variations of shrub and tree components were studied in two sites of Semideciduous Forest, initial forest and mature forest, located in the Mata do Paraíso Forest Reserve, in Viçosa, State of Minas Gerais, Southeastern Brazil, in order to analyze the floristic similarity and the correlations between environmental variables and the distribution of tree species in these forests. Individual trees with a diameter at breast height (DBH) > or = 4.8 cm were sampled in twenty 10 x 30 m plots (10 plots in each site). The plots were distributed systematically at 10 m intervals. The environmental variables analyzed were: the canopy openness and soil chemical and texture characteristics. The two forest sites showed clear differences in the levels of canopy openness and soil fertility, factors that reflect the floristic and successional differences of the shrub and tree component, revealed by the low similarity between these forests by cluster analysis. The canonical correspondence analysis (CCA) of environmental variables and species abundance indicated that the species in these forests studied are distributed under strong influence of canopy openness, moisture and soil fertility.

    2012-03-01

    Self-regulation is a core aspect of adaptive human behavior that has been studied, largely in parallel, through the lenses of social and personality psychology as well as cognitive psychology. Here, we argue for more communication between these disciplines and highlight recent research that speaks to their connection. We outline how basic facets of executive functioning (working memory operations, behavioral inhibition, and task-switching) may subserve successful self-regulation. We also argue that temporary reductions in executive functions underlie many of the situational risk factors identified in the social psychological research on self-regulation and review recent evidence that the training of executive functions holds significant potential for improving poor self-regulation in problem populations.

  8. Enhancing Writing through Strengthened Executive Function

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available We explore aspects of essay writing requiring high-level organizational capacity and executive function. The literature supports the approach that specific and focused writing-skill mastery leads to reduced anxiety and increased self-efficacy which correlates with improved writing skills. Although essay writing is a complex multi-dimensional task, two particular strategies, tree-diagram and reference methods, specifically address the organizational skills characteristic of executive function. The tree and reference methods presented in this paper address the flow of information, not content, and consequently, the methods presented in this paper apply to mathematics and English as well as to K-12 and college level.

    Komazec, Srdjan; Facca, Federico Michele

    Managing complex and distributed software systems built on top of the service-oriented paradigm has never been more challenging. While Semantic Web Service technologies offer a promising set of languages and tools as a foundation to resolve the heterogeneity and scalability issues, they are still failing to provide an autonomic execution environment. In this paper we present an approach based on Semantic Web Services to enable the monitoring and self-management of a Semantic Execution Environment (SEE), a brokerage system for Semantic Web Services. Our approach is founded on the event-triggered reactivity paradigm in order to facilitate environment control, thus contributing to its autonomicity, robustness and flexibility.

    This article presents a reconfigurable manufacturing execution system (RMES) filling the gap between enterprise resource planning and resource layer for pipe-cutting production with mass customisation and rapid adaptation to dynamic market, which consists of planning and scheduling layer and executive control layer. Starting from customer's task and process requirements, the cutting trajectories are planned under generalised mathematical model able to reconfigure in accordance with various intersecting types' joint, and all tasks are scheduled by nesting algorithm to maximise the utilisation rate of rough material. This RMES for pipe cutting has been effectively implemented in more than 100 companies.

  11. Program Execution on Reconfigurable Multicore Architectures

    Directory of Open Access Journals (Sweden)

    Sanjiva Prasad

    2016-06-01

    Full Text Available Based on the two observations that diverse applications perform better on different multicore architectures, and that different phases of an application may have vastly different resource requirements, Pal et al. proposed a novel reconfigurable hardware approach for executing multithreaded programs. Instead of mapping a concurrent program to a fixed architecture, the architecture adaptively reconfigures itself to meet the application's concurrency and communication requirements, yielding significant improvements in performance. Based on our earlier abstract operational framework for multicore execution with hierarchical memory structures, we describe execution of multithreaded programs on reconfigurable architectures that support a variety of clustered configurations. Such reconfiguration may not preserve the semantics of programs due to the possible introduction of race conditions arising from concurrent accesses to shared memory by threads running on the different cores. We present an intuitive partial ordering notion on the cluster configurations, and show that the semantics of multithreaded programs is always preserved for reconfigurations "upward" in that ordering, whereas semantics preservation for arbitrary reconfigurations can be guaranteed for well-synchronised programs. We further show that a simple approximate notion of efficiency of execution on the different configurations can be obtained using the notion of amortised bisimulations, and extend it to dynamic reconfiguration.

    Science.gov (United States)

    Mahmood, A.; Andrews, D. M.; Mccluskey, E. J.

    1984-01-01

    An executable assertion is a logical statement about the variables or a block of code. If there is no error during execution, the assertion statement results in a true value. Executable assertions can be used for dynamic testing of software. They can be employed for validation during the design phase, and exception and error detection during the operation phase. The present investigation is concerned with the problem of writing executable assertions, taking into account the use of assertions for testing flight software. They can be employed for validation during the design phase, and for exception handling and error detection during the operation phase The digital flight control system and the flight control software are discussed. The considered system provides autopilot and flight director modes of operation for automatic and manual control of the aircraft during all phases of flight. Attention is given to techniques for writing and using assertions to test flight software, an experimental setup to test flight software, and language features to support efficient use of assertions.

  18. Validating Avionics Conceptual Architectures with Executable Specifications

    Directory of Open Access Journals (Sweden)

    Nils Fischer

    2012-08-01

    Full Text Available Current avionics systems specifications, developed after conceptual design, have a high degree of uncertainty. Since specifications are not sufficiently validated in the early development process and no executable specification exists at aircraft level, system designers cannot evaluate the impact of their design decisions at aircraft or aircraft application level. At the end of the development process of complex systems, e. g. aircraft, an average of about 65 per cent of all specifications have to be changed because they are incorrect, incomplete or too vaguely described. In this paper, a model-based design methodology together with a virtual test environment is described that makes complex high level system specifications executable and testable during the very early levels of system design. An aircraft communication system and its system context is developed to demonstrate the proposed early validation methodology. Executable specifications for early conceptual system architectures enable system designers to couple functions, architecture elements, resources and performance parameters, often called non-functional parameters. An integrated executable specification at Early Conceptual Architecture Level is developed and used to determine the impact of different system architecture decisions on system behavior and overall performance.

    2014-10-01

    Organ procurement from executed prisoners in China is internationally condemned, yet this practice continues unabated in 2014. This is despite repeated announcements from Chinese authorities that constructive measures have been undertaken to conform to accepted ethical standards. While there is unanimous agreement on the unethical nature of using organs from executed prisoners, due to its limitations on voluntary and informed consent, there is insufficient coverage of forced organ procurement from prisoners of conscience without consent. Strategies to influence positive change in China over the last few decades have failed to bring this practice to an end. While organ donation and transplantation services in China have undergone considerable structural changes in the last few years, fundamental attempts to shift practice to ethically sourced organs have floundered. In this article, we discuss the organ trade in China, reflect upon organ procurement from executed prisoners (including both capital prisoners and prisoners of conscience) and provide an overview of contradictory Chinese efforts to halt forced organ procurement from executed prisoners. Finally, we highlight current actions being taken to address this issue and offer comprehensive recommendations to bring this ethically indefensible practice to an immediate end. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

  3. Central executive involvement in children's spatial memory.

    Science.gov (United States)

    Ang, Su Yin; Lee, Kerry

    2008-11-01

    Previous research with adults found that spatial short-term and working memory tasks impose similar demands on executive resources. We administered spatial short-term and working memory tasks to 8- and 11-year-olds in three separate experiments. In Experiments 1 and 2 an executive suppression task (random number generation) was found to impair performances on a short-term memory task (Corsi blocks), a working memory task (letter rotation), and a spatial visualisation task (paper folding). In Experiment 3 an articulatory suppression task only impaired performance on the working memory task. These results suggest that short-term and working memory performances are dependent on executive resources. The degree to which the short-term memory task was dependent on executive resources was expected to be related to the amount of experience children have had with such tasks. Yet we found no significant age-related suppression effects. This was attributed to differences in employment of cognitive strategies by the older children.

  6. Executive functions in persons with metabolic syndrome

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Modern man lyfestyle contributes to the increasing incidence of metabolic syndrome in the developed world. Prevalence of the metabolic syndrome in adults ranges from 20 to 25%, and it tends to increase. Each year, 3.2 million people around the world die from complications associated with this syndrome. Treatment involves cooperation of medical doctors of various specialties, but the decisive factor is patient motivation, given that the treatment requires significant lifestyle changes. Our hypothesis is that metabolic syndrome patients have reduced ability to plan, convert plan into action and effectively implement planned activities, showing signs of dysexecutive syndrome. The term executive functions comes from the English word 'executive', which also means the controlling, in neuropsychology reserved for high-level abilities that influence more basic abilities such as attention, perception, memory, thinking and speaking. The main objective of this study was to determine characteristics of executive functioning in patients with metabolic syndrome. The sample consisted of 61 subjects of both sexes, aged 20 to 60 years, divided into two groups - those with a diagnosis of metabolic syndrome and those without this diagnosis. The results suggest that people with metabolic syndrome showed significantly poorer performance in almost all indicators of executive functions, represented by Wisconsin Card Sorting Test (Wisconsin Card Sorting Test variables.

    2013-06-01

    Increasingly recognized as an important factor in the performance of complex, goal-directed tasks, executive functioning is understood in different ways across disciplines. The aim was to explore the ways in which executive functioning is conceptualized, discussed, described, and implied in the occupational therapy literature. A scoping review of the occupational therapy literature was conducted following Levac, Colquhoun, and O'Brien's (2010) recommended methodology. Executive functioning is described both as a set of performance component skills or processes and as the executive occupational performance inherent in complex occupations. Executive functioning is implicit in occupational performance and engagement, and some health conditions seem to be commonly associated with impaired executive functioning. Assessing executive functioning requires dynamic occupation- and performance-based assessment. Interventions targeting executive functioning are grounded in metacognitive approaches. Executive functioning is a complex construct that is conceptualized with considerable variance within the occupational therapy literature, creating barriers to effective service delivery.

    This study aimed to assess raw milk consumption habits in the urban population of Viçosa, Minas Gerais, Brazil, and the microbiological safety and quality of the fluid milk available in retail sales outlets in the same region. A simplified questionnaire regarding raw milk consumption was applied to the persons responsible for food acquisition in 411 residences. The regular consumption of raw milk was observed by 18.5% of the interviewers, and lack of knowledge of possible risks related to this food product. Microbiological safety and quality were assessed for raw (n=69), pasteurized (n=80), and ultra-high-temperature (UHT)-treated milk (n=80) by analyzing the counts of mesophilic aerobes, coliforms, and Escherichia coli, and detection of Listeria monocytogenes and Salmonella spp.; raw milk samples were also subjected to enumeration of coagulase-positive Staphylococcus. Concerning raw milk, 59.4% of the samples were considered as produced in inadequate hygienic conditions, 5.8% of the samples presented counts of coagulase-positive Staphylococcus lower than 100 colony-forming units (CFU)/mL, and no samples presented with positive results for L. monocytogenes or Salmonella spp. All pasteurized and UHT milk samples presented with low counts of mesophilic aerobes and coliforms, while L. monocytogenes and Salmonella spp. were absent. The data demonstrated that raw milk was consumed by the population studied. Despite the absence of potential hazards, raw milk was of poor hygienic quality, in contrast with the processed fluid milk available in retail sales outlets that was safe and of good hygienic quality, highlighting the suitability of pasteurized and UHT milk for human consumption.

    Executive functions might be important for successful performance in sports, particularly in team sports requiring quick anticipation and adaptation to continuously changing situations in the field. The executive functions motor inhibition, attention and visuospatial working memory were examined in highly talented soccer players. Eighty-four highly talented youth soccer players (mean age 11.9), and forty-two age-matched amateur soccer players (mean age 11.8) in the age range 8 to 16 years performed a Stop Signal task (motor inhibition), the Attention Network Test (alerting, orienting, and executive attention) and a visuospatial working memory task. The highly talented soccer players followed the talent development program of the youth academy of a professional soccer club and played at the highest national soccer competition for their age. The amateur soccer players played at a regular soccer club in the same geographical region as the highly talented soccer players and play in a regular regional soccer competition. Group differences were tested using analyses of variance. The highly talented group showed superior motor inhibition as measured by stop signal reaction time (SSRT) on the Stop Signal task and a larger alerting effect on the Attention Network Test, indicating an enhanced ability to attain and maintain an alert state. No group differences were found for orienting and executive attention and visuospatial working memory. A logistic regression model with group (highly talented or amateur) as dependent variable and executive function measures that significantly distinguished between groups as predictors showed that these measures differentiated highly talented soccer players from amateur soccer players with 89% accuracy. Highly talented youth soccer players outperform youth amateur players on suppressing ongoing motor responses and on the ability to attain and maintain an alert state; both may be essential for success in soccer.

  1. Unraveling Executive Functioning in Dual Diagnosis.

    Duijkers, Judith C L M; Vissers, Constance Th W M; Egger, Jos I M

    2016-01-01

    In mental health, the term dual-diagnosis is used for the co-occurrence of Substance Use Disorder (SUD) with another mental disorder. These co-occurring disorders can have a shared cause, and can cause/intensify each other's expression. Forming a threat to health and society, dual-diagnosis is associated with relapses in addiction-related behavior and a destructive lifestyle. This is due to a persistent failure to control impulses and the maintaining of inadequate self-regulatory behavior in daily life. Thus, several aspects of executive functioning like inhibitory, shifting and updating processes seem impaired in dual-diagnosis. Executive (dys-)function is currently even seen as a shared underlying key component of most mental disorders. However, the number of studies on diverse aspects of executive functioning in dual-diagnosis is limited. In the present review, a systematic overview of various aspects of executive functioning in dual-diagnosis is presented, striving for a prototypical profile of patients with dual-diagnosis. Looking at empirical results, inhibitory and shifting processes appear to be impaired for SUD combined with schizophrenia, bipolar disorder or cluster B personality disorders. Studies involving updating process tasks for dual-diagnosis were limited. More research that zooms in to the full diversity of these executive functions is needed in order to strengthen these findings. Detailed insight in the profile of strengths and weaknesses that underlies one's behavior and is related to diagnostic classifications, can lead to tailor-made assessment and indications for treatment, pointing out which aspects need attention and/or training in one's self-regulative abilities.

The executive functions motor inhibition, attention and visuospatial working memory were examined in highly talented soccer players. Eighty-four highly talented youth soccer players (mean age 11.9, and forty-two age-matched amateur soccer players (mean age 11.8 in the age range 8 to 16 years performed a Stop Signal task (motor inhibition, the Attention Network Test (alerting, orienting, and executive attention and a visuospatial working memory task. The highly talented soccer players followed the talent development program of the youth academy of a professional soccer club and played at the highest national soccer competition for their age. The amateur soccer players played at a regular soccer club in the same geographical region as the highly talented soccer players and play in a regular regional soccer competition. Group differences were tested using analyses of variance. The highly talented group showed superior motor inhibition as measured by stop signal reaction time (SSRT on the Stop Signal task and a larger alerting effect on the Attention Network Test, indicating an enhanced ability to attain and maintain an alert state. No group differences were found for orienting and executive attention and visuospatial working memory. A logistic regression model with group (highly talented or amateur as dependent variable and executive function measures that significantly distinguished between groups as predictors showed that these measures differentiated highly talented soccer players from amateur soccer players with 89% accuracy. Highly talented youth soccer players outperform youth amateur players on suppressing ongoing motor responses and on the ability to attain and maintain an alert state; both may be essential for success in soccer.

    Full Text Available En todo el mundo, las invasiones de especies leñosas exóticas están amenazando las funciones ecosistémicas. La dispersión y el subsecuente reemplazo de bosques de especies nativas por comunidades dominadas por exóticas es evidente, particularmente, en proximidad a centros urbanos donde la presión de propágulos de especies exóticas es alta. Sin embargo, existe una falta de información sobre los factores ambientales que subyacen este reemplazo. En este estudio nos propusimos responder las siguientes preguntas: (1 ¿se observa una segregación espacial a escala local entre especies leñosas exóticas y/o nativas dominantes?, y (2 si existe esa segregación, ¿está asociada a variables ambientales? En el 2010 se establecieron 31 parcelas distribuidas en 16 laderas en los bosques Chaqueños de las Sierras de Córdoba, en Argentina central. En cada uno de los sitios de muestreo se relevó la composición y abundancia de todas las especies leñosas con un diámetro a la altura de la base superior a 5cm. Para caracterizar el ambiente en cada una de las parcelas medimos la posición topográfica (pendiente y orientación y algunas propiedades asociadas con la física (densidad aparente y compactación, estructura (profundidad y textura y con la química (pH y el contenido de nutrientes y agua del suelo.

    1990-09-01

    The growth of corporate orientation for health care structures, with a focus on bottom-line management, has radically altered the role of nurse executives. With the organization's emphasis on performance, productivity, and results, successful nurse executives are now integrating the management of the delivery of nursing care with the management of complex corporate structures and relationships. The editor of Executive Development discusses the rapidly changing expectations and demands of the contemporary nurse executive's work. The nurse executive's role can be viewed from many perspectives: its scope, its value, its structure, its content. Content--"What does the nurse executive do that makes a real difference?"--is the focus here.

    A computer-implemented software self-assembled system and method for providing an external override and monitoring capability to dynamically self-assembling software containing machines that self-assemble execution sequences and data structures. The method provides an external override machine that can be introduced into a system of self-assembling machines while the machines are executing such that the functionality of the executing software can be changed or paused without stopping the code execution and modifying the existing code. Additionally, a monitoring machine can be introduced without stopping code execution that can monitor specified code execution functions by designated machines and communicate the status to an output device.

  17. Early executive function predicts reasoning development.

    Richland, Lindsey E; Burchinal, Margaret R

    2013-01-01

    Analogical reasoning is a core cognitive skill that distinguishes humans from all other species and contributes to general fluid intelligence, creativity, and adaptive learning capacities. Yet its origins are not well understood. In the study reported here, we analyzed large-scale longitudinal data from the Study of Early Child Care and Youth Development to test predictors of growth in analogical-reasoning skill from third grade to adolescence. Our results suggest an integrative resolution to the theoretical debate regarding contributory factors arising from smaller-scale, cross-sectional experiments on analogy development. Children with greater executive-function skills (both composite and inhibitory control) and vocabulary knowledge in early elementary school displayed higher scores on a verbal analogies task at age 15 years, even after adjusting for key covariates. We posit that knowledge is a prerequisite to analogy performance, but strong executive-functioning resources during early childhood are related to long-term gains in fundamental reasoning skills.

    Platform virtualization helps solving major grid computing challenges: share resource with flexible, user-controlled and custom execution environments and in the meanwhile, isolate failures and malicious code. Grid resource management tools will evolve to embrace support for virtual resource. We present two open source projects that transparently supply virtual execution environments. Tycoon has been developed at HP Labs to optimise resource usage in creating an economy where users bid to access virtual machines and compete for CPU cycles. SmartDomains provides a peer-to-peer layer that automates virtual machines deployment using a description language and deployment engine from HP Labs. These projects demonstrate both client-server and peer-to-peer approaches to virtual resource management. The first case makes extensive use of virtual machines features for dynamic resource allocation. The second translates virtual machines capabilities into a sophisticated language where resource management components can b...

    Full Text Available This article describes psychological challenges that executive leaders of companies face nowadays. The study of the social context is based on changes that took place with the development of information technologies. The analysis touches upon such phenomena as virtualization, involvement in the external sociocommunicative environment, and the emergence of multiple identity. It is suggested that in order to adapt to changing conditions one should follow the path of self-development—in particular, to develop attention, imagination, and willpower. In connection with the traits generally attributed to executive leaders, the article emphasizes self-adjustment; common sense as an integral part of intuition, emotions, and imagination; and the readiness to make choices in fifty-fifty situations.

A similar measure in California was also dropped by the SEIU in 2014. Supporters of the proposal said it would decrease escalating healthcare costs. Opponents of the measure, including the Arizona Chamber of Commerce who filed the suit challenging the proposition, alleged that it would lead to poorer healthcare.

  1. NHS trust chief executives as heroes?

    Science.gov (United States)

    Learmonth, M

    2001-01-01

    This paper presents a reading of the transcripts of interviews with NHS Trust Chief Executives. Using a poststructuralist understanding of the interviews, it privileges a reading that (ironically) represents these Chief Executives as heroes. Following the classic hero story line, they leave the civilized order of home and journey into a threatening wilderness where they encounter dangerous and magical things but overcome them all because of their masculine characteristics such as rationality, strength and resourcefulness. One way in which these stories can be understood to have significance is that they (misleadingly but powerfully) portray management as obvious and necessary by evocatively drawing on a myth of ancient origin. The piece concludes with some reflections on the ontological implications of the analysis and reflexive comments on the production of truth as a problem.

    2007-02-01

    When attention is engaged in a task, unexpected events in the visual scene may go undetected, a phenomenon known as inattentional blindness (IB). At what stage of information processing must attention be engaged for IB to occur? Although manipulations that tax visuospatial attention can induce IB, the evidence is more equivocal for tasks that engage attention at late, central stages of information processing. Here, we tested whether IB can be specifically induced by central executive processes. An unexpected visual stimulus was presented during the retention interval of a working memory task that involved either simply maintaining verbal material or rearranging the material into alphabetical order. The unexpected stimulus was more likely to be missed during manipulation than during simple maintenance of the verbal information. Thus, the engagement of executive processes impairs the ability to detect unexpected, task-irrelevant stimuli, suggesting that IB can result from central, amodal stages of processing.

    Full Text Available Executive Function (EF refers to important socio-emotional and cognitive skills that are known to be highly correlated with both academic and life success. EF is a blanket term that is considered to include self-regulation, working memory, and planning. Recent studies have shown a relationship between EF and motor control. The emergence of motor control coincides with that of EF, hence understanding the relationship between these two domains could have significant implications for early detection and remediation of later EF deficits. The purpose of the current study was to investigate this relationship in young children. This study incorporated the Behavioural Rating Inventory of Executive Function (BRIEF and two motor assessments with a focus on precision grasping to test this hypothesis. The BRIEF is comprised of two indices of EF: 1 the Behavioral Regulation Index (BRI containing three subscales: Inhibit, Shift, and Emotional Control; 2 the Metacognition Index (MI containing five subscales: Initiate, Working Memory, Plan/Organize, Organization of Materials, and Monitor. A global executive composite (GEC is derived from the two indices. In this study, right-handed children aged 5-6 and 9-10 were asked to: grasp-to-construct (Lego® models; and grasp-to-place (wooden blocks, while their parents completed the BRIEF questionnaire. Analysis of results indicated significant correlations between the strength of right hand preference for grasping and numerous elements of the BRIEF including the BRI, MI, and GEC. Specifically, the more the right hand was used for grasping the better the EF ratings. In addition, patterns of space-use correlated with the GEC in several subscales of the BRIEF. Finally and remarkably, the results also showed a reciprocal relationship between hand and space use for grasping and EF. These findings are discussed with respect to: 1 the developmental overlap of motor and executive functions; 2 detection of EF deficits through

  8. Cognitive programs: Software for attention's executive

    Full Text Available What are the computational tasks that an executive controller for visual attention must solve? This question is posed in the context of the Selective Tuning model of attention. The range of required computations go beyond top-down bias signals or region-of-interest determinations, and must deal with overt and covert fixations, process timing and synchronization, information routing, memory, matching control to task, spatial localization, priming, and coordination of bottom-up with top-down information. During task execution, results must be monitored to ensure the expected results. This description includes the kinds of elements that are common in the control of any kind of complex machine or system. We seek a mechanistic integration of the above, in other words, algorithms that accomplish control. Such algorithms operate on representations, transforming a representation of one kind into another, which then forms the input to yet another algorithm. Cognitive Programs (CPs are hypothesized to capture exactly such representational transformations via stepwise sequences of operations. CPs, an updated and modernized offspring of Ullman's Visual Routines, impose an algorithmic structure to the set of attentional functions and play a role in the overall shaping of attentional modulation of the visual system so that it provides its best performance. This requires that we consider the visual system as a dynamic, yet general-purpose processor tuned to the task and input of the moment. This differs dramatically from the almost universal cognitive and computational views, which regard vision as a passively observing module to which simple questions about percepts can be posed, regardless of task. Differing from Visual Routines, CPs explicitly involve the critical elements of Visual Task Executive, Visual Attention Executive, and Visual Working Memory. Cognitive Programs provide the software that directs the actions of the Selective Tuning model of visual

  11. Executive dysfunction in high functioning autism

    OpenAIRE

    Burnett, Hollie

    2017-01-01

    Background: There is presently a lack of consistency in research designed to measure executive functioning (EF) in autism that may be attributable to lack of homogeneity or comorbid conditions (i.e. learning disability or additional diagnosis) in test samples. Aim: A systematic review focused on a subset of EF (verbal fluency: VF) was conducted, using only studies of high-functioning individuals with autism (HFA) without an additional diagnosis or learning disability.

    This document presents the Executive Summary, the first of six volumes comprising the 2006 Baseline Technical Report (BTR) for the international FAIR project (Facility for Antiproton and Ion Research). The BTR provides the technical description, cost, schedule, and assessments of risk for the proposed new facility. The purpose of the BTR is to provide a reliable basis for the construction, commissioning and operation of FAIR. The BTR is one of the central documents requested by the FAIR International Steering Committee (ISC) and its working groups, in order to prepare the legal process and the decisions on the construction and operation of FAIR in an international framework. It provides the technical basis for legal contracts on contributions to be made by, so far, 13 countries within the international FAIR Consortium. The BTR begins with this extended Executive Summary as Volume 1, which is also intended for use as a stand-alone document. The Executive Summary provides brief summaries of the accelerator facilities, the scientific programs and experimental stations, civil construction and safety, and of the workproject structure, costs and schedule.

  15. The contribution of executive control to semantic cognition: Convergent evidence from semantic aphasia and executive dysfunction.

    Thompson, Hannah E; Almaghyuli, Azizah; Noonan, Krist A; Barak, Ohr; Lambon Ralph, Matthew A; Jefferies, Elizabeth

    2018-01-03

    Semantic cognition, as described by the controlled semantic cognition (CSC) framework (Rogers et al., , Neuropsychologia, 76, 220), involves two key components: activation of coherent, generalizable concepts within a heteromodal 'hub' in combination with modality-specific features (spokes), and a constraining mechanism that manipulates and gates this knowledge to generate time- and task-appropriate behaviour. Executive-semantic goal representations, largely supported by executive regions such as frontal and parietal cortex, are thought to allow the generation of non-dominant aspects of knowledge when these are appropriate for the task or context. Semantic aphasia (SA) patients have executive-semantic deficits, and these are correlated with general executive impairment. If the CSC proposal is correct, patients with executive impairment should not only exhibit impaired semantic cognition, but should also show characteristics that align with those observed in SA. This possibility remains largely untested, as patients selected on the basis that they show executive impairment (i.e., with 'dysexecutive syndrome') have not been extensively tested on tasks tapping semantic control and have not been previously compared with SA cases. We explored conceptual processing in 12 patients showing symptoms consistent with dysexecutive syndrome (DYS) and 24 SA patients, using a range of multimodal semantic assessments which manipulated control demands. Patients with executive impairments, despite not being selected to show semantic impairments, nevertheless showed parallel patterns to SA cases. They showed strong effects of distractor strength, cues and miscues, and probe-target distance, plus minimal effects of word frequency on comprehension (unlike semantic dementia patients with degradation of conceptual knowledge). This supports a component process account of semantic cognition in which retrieval is shaped by control processes, and confirms that deficits in SA patients reflect

  18. Autonomous execution of the Precision Immobilization Technique

    Mascareñas, David D. L.; Stull, Christopher J.; Farrar, Charles R.

    2017-03-01

    Over the course of the last decade great advances have been made in autonomously driving cars. The technology has advanced to the point that driverless car technology is currently being tested on publicly accessed roadways. The introduction of these technologies onto publicly accessed roadways not only raises questions of safety, but also security. Autonomously driving cars are inherently cyber-physical systems and as such will have novel security vulnerabilities that couple both the cyber aspects of the vehicle including the on-board computing and any network data it makes use of, with the physical nature of the vehicle including its sensors, actuators, and the vehicle chassis. Widespread implementation of driverless car technology will require that both the cyber, as well as physical security concerns surrounding these vehicles are addressed. In this work, we specifically developed a control policy to autonomously execute the Precision Immobilization Technique, a.k.a. the PIT maneuver. The PIT maneuver was originally developed by law enforcement to end high-speed vehicular pursuits in a quasi-safe manner. However, there is still a risk of damage/roll-over to both the vehicle executing the PIT maneuver as well as to the vehicle subject to the PIT maneuver. In law enforcement applications, it would be preferable to execute the PIT maneuver using an autonomous vehicle, thus removing the danger to law-enforcement officers. Furthermore, it is entirely possible that unscrupulous individuals could inject code into an autonomously-driving car to use the PIT maneuver to immobilize other vehicles while maintaining anonymity. For these reasons it is useful to know how the PIT maneuver can be implemented on an autonomous car. In this work a simple control policy based on velocity pursuit was developed to autonomously execute the PIT maneuver using only a vision and range measurements that are both commonly collected by contemporary driverless cars. The ability of this

  20. The Impact of Hedge Fund Activism on Target Firm Performance, Executive Compensation and Executive Wealth

    Directory of Open Access Journals (Sweden)

    Andrew Carrothers

    2017-10-01

    Full Text Available This paper examines the relationship between hedge fund activism and target firm performance, executive compensation, and executive wealth. It introduces a theoretical framework that describes the activism process as a sequence of discrete decisions. The methodology uses regression analysis on a matched sample based on firm size, industry, and market-to-book ratio. All regressions control for industry and year fixed effects. Schedule 13D Securities and Exchange Commission (SEC filings are the source for the statistical sample of hedge fund target firms. I supplement that data with target firm financial, operating, and share price information from the CRSP-COMPUSTAT merged database. Activist hedge funds target undervalued or underperforming firms with high profitability and cash flows. They do not avoid firms with powerful CEOs. Leverage, executive compensation, pay for performance and CEO turnover increase at target firms after the arrival of the activist hedge fund. Target firm executives’ wealth is more sensitive to changes in share price after hedge fund activism events suggesting that the executive team experiences changes to their compensation structure that provides incentive to take action to improve returns to shareholders. The top executives reap rewards for increasing firm value but not for increased risk taking.

  1. Commentary: Mentoring the mentor: executive coaching for clinical departmental executive officers.

    Science.gov (United States)

    Geist, Lois J; Cohen, Michael B

    2010-01-01

    Departmental executive officers (DEOs), department chairs, and department heads in medical schools are often hired on the basis of their accomplishments in research as well as their skills in administration, management, and leadership. These individuals are also expected to be expert in multiple areas, including negotiation, finance and budgeting, mentoring, and personnel management. At the same time, they are expected to maintain and perhaps even enhance their personal academic standing for the purposes of raising the level of departmental and institutional prestige and for recruiting the next generation of physicians and scientists. In the corporate world, employers understand the importance of training new leaders in requisite skill enhancement that will lead to success in their new positions. These individuals are often provided with extensive executive training to develop the necessary competencies to make them successful leaders. Among the tools employed for this purpose are the use of personal coaches or executive training courses. The authors propose that the use of executive coaching in academic medicine may be of benefit for new DEOs. Experience using an executive coach suggests that this was a valuable growth experience for new leaders in the institution.

    2012-10-01

    Effects of initiation of continuous positive airway pressure (CPAP) therapy on EEG background activity were investigated in patients with obstructive sleep apnea syndrome (OSAS, N = 25) to test possible reversibility of alterations of brain electrical activity caused by chronic hypoxia. Normal control group (N = 14) was also examined. Two EEG examinations were done in each groups: at night and in the next morning. Global and regional (left vs. right, anterior vs. posterior) measures of spatial complexity (Omega complexity) were used to characterize the degree of spatial synchrony of EEG. Low resolution electromagnetic tomography (LORETA) was used to localize generators of EEG activity in separate frequency bands. Before CPAP-treatment, a significantly lower Omega complexity was found globally and over the right hemisphere. Due to CPAP-treatment, these significant differences vanished. Significantly decreased Omega complexity was found in the anterior region after treatment. LORETA showed a decreased activity in all of the beta bands after therapy in the right hippocampus, premotor and temporo-parietal cortex, and bilaterally in the precuneus, paracentral and posterior cingulate cortex. No significant changes were seen in control group. Comparing controls and patients before sleep, an increased alpha2 band activity was seen bilaterally in the precuneus, paracentral and posterior cingulate cortex, while in the morning an increased beta3 band activity in the left precentral and bilateral premotor cortex and a decreased delta band activity in the right temporo-parietal cortex and insula were observed. These findings indicate that effect of sleep on EEG background activity is different in OSAS patients and normal controls. In OSAS patients, significant changes lead to a more normal EEG after a night under CPAP-treatment. Compensatory alterations of brain electrical activity in regions associated with influencing sympathetic outflow, visuospatial abilities, long

    Full Text Available The study examines the relationship between executive compensation and firm performance among Indian firms. The evidence suggests that firm performance measured by accounting, as well as market-based measures, significantly affects executive compensation. We also test for the presence of persistence in executive compensation by employing the system-generalised methods of moments (GMM estimator. We find significant persistence in executive compensation among the sample firms. Further, we report the absence of pay–performance relationship among the smaller sample firms and business group affiliated firms. Thus, our findings cast doubts over the performance-based executive compensation practices of Indian business group affiliated firms.

    Huang, Wei-Min

    2013-01-01

    Existing health information systems largely only support the daily operations of a medical centre, and are unable to generate the information required by executives for decision-making. Building on past research concerning information retrieval behaviour and learning through mental models, this study examines the use of information systems by hospital executives in medical centres. It uses a structural equation model to help find ways hospital executives might use information systems more effectively. The results show that computer self-efficacy directly affects the maintenance of mental models, and that system characteristics directly impact learning styles and information retrieval behaviour. Other results include the significant impact of perceived environmental uncertainty on scan searches; information retrieval behaviour and focused searches on mental models and perceived efficiency; scan searches on mental model building; learning styles and model building on perceived efficiency; and finally the impact of mental model maintenance on perceived efficiency and effectiveness.

  12. Nurse executive transformational leadership found in participative organizations.

    Dunham-Taylor, J

    2000-05-01

    The study examined a national sample of 396 randomly selected hospital nurse executives to explore transformational leadership, stage of power, and organizational climate. Results from a few nurse executive studies have found nurse executives were transformational leaders. As executives were more transformational, they achieved better staff satisfaction and higher work group effectiveness. This study integrates Bass' transformational leadership model with Hagberg's power stage theory and Likert's organizational climate theory. Nurse executives (396) and staff reporting to them (1,115) rated the nurse executives' leadership style, staff extra effort, staff satisfaction, and work group effectiveness using Bass and Avolio's Multifactor Leadership Questionnaire. Executives' bosses (360) rated executive work group effectiveness. Executives completed Hagberg's Personal Power Profile and ranked their organizational climate using Likert's Profile of Organizational Characteristics. Nurse executives used transformational leadership fairly often; achieved fairly satisfied staff levels; were very effective according to bosses; were most likely at stage 3 (power by achievement) or stage 4 (power by reflection); and rated their hospital as a Likert System 3 Consultative Organization. Staff satisfaction and work group effectiveness decreased as nurse executives were more transactional. Higher transformational scores tended to occur with higher educational degrees and within more participative organizations. Transformational qualities can be enhanced by further education, by achieving higher power stages, and by being within more participative organizations.

    Full Text Available In the aftermath of the financial crisis, executive compensation abuse has been deeply criticized. Thus, the actuality of research is undeniable. The article highlights the importance of learning from other institutions’ past and present executive compensation abuse experiences by presenting the participants’ shared experiences (having to do with executive compensation abuse and by studying how participants perceive executive compensation abuse. The main objective of this research lies in exploring participants’ shared experiences concerning executive compensation abuse, as well as their perceptions, discrepancies and unsolved questions – presented within an ample, interconnected qualitative and quantitative methodological approach. A sample of 20 individuals was chosen for the triangulation method. From the resultant triangulation six new themes derive from the interview/questionnaire questions specifically referring to executive payment abuse namely: (a ethics means distinguishing between right and wrong, (b perspectives of ethical behaviour, (c types of executive payment abuse, (d the participant’s perceptions of institution and colleagues.

  14. Evidence of dopaminergic processing of executive inhibition.

    Directory of Open Access Journals (Sweden)

    Rajendra D Badgaiyan

    Full Text Available Inhibition of unwanted response is an important function of the executive system. Since the inhibitory system is impaired in patients with dysregulated dopamine system, we examined dopamine neurotransmission in the human brain during processing of a task of executive inhibition. The experiment used a recently developed dynamic molecular imaging technique to detect and map dopamine released during performance of a modified Eriksen's flanker task. In this study, young healthy volunteers received an intravenous injection of a dopamine receptor ligand ((11C-raclopride after they were positioned in the PET camera. After the injection, volunteers performed the flanker task under Congruent and Incongruent conditions in a single scan session. They were required to inhibit competing options to select an appropriate response in the Incongruent but not in the Congruent condition. The PET data were dynamically acquired during the experiment and analyzed using two variants of the simplified reference region model. The analysis included estimation of a number of receptor kinetic parameters before and after initiation of the Incongruent condition. We found increase in the rate of ligand displacement (from receptor sites and decrease in the ligand binding potential in the Incongruent condition, suggesting dopamine release during task performance. These changes were observed in small areas of the putamen and caudate bilaterally but were most significant on the dorsal aspect of the body of left caudate. The results provide evidence of dopaminergic processing of executive inhibition and demonstrate that neurochemical changes associated with cognitive processing can be detected and mapped in a single scan session using dynamic molecular imaging.

    Full Text Available This article starts with a literary review of the conceptual frames through which esport has been labeled academically. It shows how the concept of “electronic” has been taken as the core term for labelingesport, often accompanied by a strong emphasis on “professionalism.” The literary review is followed by the submission of an alternative conceptual frame based on the economic notion of executive ownership, which provides a theoretical grounding for esport as a cultural phenomenon. In accordance with the above, the article concludes with a reframed look at the history of esport and suggests commercial analog gaming (especially Magic: The Gathering as its point of origin.

H. Tammsaare’s five-volume novel Truth and Justice (Tõde ja Õigus has received quite a bit of scholarly attention. However, up till now there have been few treatments of dialect in characters’ speech that also take into account the coherence of context and the writer’s aesthetic goals. Features of dialect in characters’ speech have been noticed by many researchers, but they mostly limited themselves to giving descriptive accounts of dialect words. These earlier accounts often approached these passages as authentic specimens of dialect, and did not interpret them in context or as aspects of literary form. This article is based on the literary dialect theory of linguist and literary scholar Sumner Ives, who argues from the principle that dialect phenomena in literature cannot be studied as authentic specimens of dialect. In literature, when characters speak in dialect, this serves goals related to the content and composition of the work, and does not attempt to be a precise representation of real dialect speech. In this spirit, I will examine dialect in the characters’ speech in the first volume of Tammsaare’s cycle of novels Truth and Justice

    Full Text Available Executive Functions (EF concern a range of abilities including problem-solving, planning, initiation, selfmonitoring,conscious attention, cope with new situations and the ability to modify plans if necessary. It’s a high cognitive function that is crucial for a person to get engaged and maintain daily activities whilst keeping a good quality of life. Problems in the EF were formerly known as Dysexecutive Syndrome (DS. There are many models concerning DS, although the literature on the subject still remains unclear. Several works appoint the effects brought by elderly life, as well as abuse of drugs and some psychopathologies. These factors are known to increase the distress of the frontal circuits and that could be associated to executive deficits. The effects of DS would compromise individuals in day-to-day routine, academic, social and labor fields. There is a growing body of studies trying to determine the causes, implications, associations and the best way to take care of these effects. This work intends to review DS, focusing on the most important fields related to this area, such as psychopathology associations, cognitive reserve, assessment and cognitive rehabilitation programs.

    As women have been nursing since the earliest days of recorded civilization, so nurses have been associated with health care since the earliest days of recorded medical history. Gender and function have been inextricably woven in ways that created a struggle for success within a male-dominated industry. Nurses, as women, have been undervalued as, until recently, their role in health care has been similarly undervalued. Changing realities in the health care environment have created an opportunity for women's unique skills and talents to be revalued in a way that offers new opportunities for nurses. Teamwork, global thinking, multitasking, creativity, and flexibility are characteristics that have assumed new importance in the marketplace. Nursing leaders possess these attributes, along with a strong clinical foundation that is integrated with knowledge of sound business principles. This combination now positions nurse executives to reach the highest levels of heath care administration. Critical to this achievement is the professional credibility obtained through education at the master's degree level in health care and nursing administration programs that provide the essential tools for professional success. New opportunities for nurse executives afford educators in health care and nursing administration similar opportunities to develop and market programs to this large group of health care professionals who are seeking graduate education in increasing numbers.

    2011-01-01

    We describe the current state-of-the-art in Trusted Computing Technologies - focusing mainly on Intel's Trusted Execution Technology (TXT). This document is based on existing documentation and tests of two existing TXT-based systems: Intel's Trusted Boot and Invisible Things Lab's Qubes OS. We describe what features are lacking in current implementations, describe what a mature system could provide, and present a list of developments to watch. Critical systems perform operation-critical computations on high importance data. In such systems, the inputs, computation steps, and outputs may be highly sensitive. Sensitive components must be protected from both unauthorized release, and unauthorized alteration: Unauthorized users should not access the sensitive input and sensitive output data, nor be able to alter them; the computation contains intermediate data with the same requirements, and executes algorithms that the unauthorized should not be able to know or alter. Due to various system requirements, such critical systems are frequently built from commercial hardware, employ commercial software, and require network access. These hardware, software, and network system components increase the risk that sensitive input data, computation, and output data may be compromised.

  4. The Executive Control of Face Memory

    Directory of Open Access Journals (Sweden)

    Steven Z. Rapcsak

    2011-01-01

    Full Text Available Patients with frontal lobe damage and cognitively normal elderly individuals demonstrate increased susceptibility to false facial recognition. In this paper we review neuropsychological evidence consistent with the notion that the common functional impairment underlying face memory distortions in both subject populations is a context recollection/source monitoring deficit, coupled with excessive reliance on relatively preserved facial familiarity signals in recognition decisions. In particular, we suggest that due to the breakdown of strategic memory retrieval, monitoring, and decision operations, individuals with frontal lobe impairment caused by focal damage or age-related functional decline do not have a reliable mechanism for attributing the experience of familiarity to the correct context or source. Memory illusions are mostly apparent under conditions of uncertainty when the face cue does not directly elicit relevant identity-specific contextual information, leaving the source of familiarity unspecified or ambiguous. Based on these findings, we propose that remembering faces is a constructive process that requires dynamic interactions between temporal lobe memory systems that operate in an automatic or bottom-up fashion and frontal executive systems that provide strategic top-down control of recollection. Executive memory control functions implemented by prefrontal cortex play a critical role in suppressing false facial recognition and related source memory misattributions.

  5. ROUTING FINANCIAL FLOWS AT THE EXECUTION OF THE MUNICIPALITY BUDGET

    Full Text Available Economic development of each administrative-territorial unit is an important factor in the economic development of the Russian Federation. In its turn, the effective execution of the budget at each level of the budget system is invariably topical, influencing the development of a system of both centralized and decentralized finance. The paramount characteristic of the organization of the budget execution of the municipality is an ability to ensure the timely and full execution of their commitments. There is a direct correlation of the budget process on both the revenue and expenditure sides. Cash gap in the local budget execution is actually quite common and, usually, inevitable, because revenues are coming unevenly during the financial year, budgetary expenditures are seasonal, and this threatens the execution of planned budgets; there is a need to raise funds. The article deals with the execution of the cash balance plan, cash flow at the single account of budget, debt and source of financing deficits. The analysis of financial flows in the execution of municipalities’ budget shows problems of execution of budget revenues and allows assessing the scale of emerging cash gaps. An outcome of the review consists in the recognition of an objective need to develop approaches to assessing the effectiveness of budget execution at all its stages and to implement the monitoring of the effectiveness of budget execution and timely effective measures for ensuring its high-quality.

  6. Repetitive thinking, executive functioning, and depressive mood in the elderly.

    2017-11-01

    Previous findings and the depressive-executive dysfunction hypothesis suggest that the established association between executive functioning and depression is accounted for by repetitive thinking. Investigating the association between executive functioning, repetitive thinking, and depressive mood, the present study empirically tested this mediational model in a sample of older adults, while focusing on both concrete and abstract repetitive thinking. This latter distinction is important given the potential protective role of concrete repetitive thinking, in contrast to the depletive effect of abstract repetitive thinking. A sample of 43 elderly volunteers, between 75 and 95 years of age, completed tests of executive functioning (the Stroop test, the Trail Making test, and the Fluency test), and questionnaires of repetitive thinking and depression. Positive correlations were observed between abstract repetitive thinking and depressive mood, and between concrete repetitive thinking and executive functioning; a negative correlation was observed between depressive mood and executive functioning. Further, mediational analysis evidenced that the relation between executive functioning and depressive mood was mediated by abstract repetitive thinking. The present data provide, for the first time, empirical support to the depressive-executive dysfunction hypothesis: the lack of executive resources would favor a mode of abstract repetitive thinking, which in turn would deplete mood. It suggests that clinical intervention targeting depression in the elderly should take into consideration repetitive thinking modes and the executive resources needed to disengage from rumination.

    e-Health is here to stay and experts predict that the Internet will become the hub of health care. Rapid advancements in biotechnology and medical research, increasingly curious patients who surf the Internet for medical information, and pressures from managed care companies to contain costs and speed treatments are the central components driving e-health. Despite physician reluctance to embrace the e-revolution, many hospitals and medical groups are employing the Internet and information technology to improve their customer interface, as well as to reduce business costs. This article offers seven e-strategies for health care performance improvement: (1) Supply chain management; (2) e-transactions; (3) care management; (4) improving quality; (5) boosting revenues; (6) outsourcing; and (7) provider networks (Intranets). By helping to incorporate these key e-solutions, physician executives can position their organizations for success in the new millennium.

Our semantics enables distributed code generation for Statemate models in the context of rapid prototyping for embedded control applications. We argue that it seems impossible to efficiently generate......, the changes made regarding the interaction of distributed model parts are similar to the interaction between the model and its environment in the original semantics, thus giving designers a familiar execution model. The semantics has been implemented in Grace, a framework for rapid prototyping code generation...... distributed code using the original Statemate semantics. The new, distributed semantics has the advantages that, first, it enables the generation of efficient distributed code, second, it preserves many aspects of the original semantics for those parts of a model that are not distributed, and third...

    Predicting the climate change impact on biodiversity and ecosystems, advancing our knowledge of environmental phenomena interconnection, assessing the validity of simulations and other key challenges of Earth Sciences require intensive use of environmental modeling. The complexity of Earth system requires the use of more than one model (often from different disciplines) to represent complex processes. The identification of appropriate mechanisms for reuse, chaining and composition of environmental models is considered a key enabler for an effective uptake of a global Earth Observation infrastructure, currently pursued by the international geospatial research community. The Group on Earth Observation (GEO) Model Web initiative aims to increase present accessibility and interoperability of environmental models, allowing their flexible composition into complex Business Processes (BPs). A few, basic principles are at the base of the Model Web concept (Nativi, et al.): 1. Open access 2. Minimal entry-barriers 3. Service-driven approach 4. Scalability In this work we propose an architectural solution aiming to contribute to the Model Web vision. This solution applies the Brokering approach for facilitiating complex multidisciplinary interoperability. The Brokering approach is currently adopted in the new GEOSS Common Infrastructure (GCI) as was presented at the last GEO Plenary meeting in Istanbul, November 2011. According to the Brokering principles, the designed system is flexible enough to support the use of multiple BP design (visual) tools, heterogeneous Web interfaces for model execution (e.g. OGC WPS, WSDL, etc.), and different Workflow engines. We designed and prototyped a component called BP Broker that is able to: (i) read an abstract BP, (ii) "compile" the abstract BP into an executable one (eBP) - in this phase the BP Broker might also provide recommendations for incomplete BPs and parameter mismatch resolution - and (iii) finally execute the eBP using a

Using the semi structured  interviews with Indonesian executives/informants of Indonesian companies, this study found that CSR practices have been viewed as philanthropic activities of companies with all the consequences that follow: shareholder as the most important stakeholder, reporting CSR practice as means to have public image and no need to have any standard to prepare CSR practice reporting. Given the findings, there is a need to redefine CSR based on the intention to maintain good relationship with stakeholders and to have the integrated management system to help management well interact with them in market and non- market mechanism.

    The existence of outstanding cognitive talent in mentally retarded subjects persists as a challenge to present knowledge. We report the case of a 16-year-old male patient with exceptional mental calculation abilities and moderate mental retardation. The patient was clinically evaluated. Data from standard magnetic resonance imaging (MRI) and two 99mTc-ethyl cysteine dimer (ECD)-single photon emission computer tomography (SPECT) (in resting condition and performing a mental calculation task) studies were analyzed. Main neurologic findings were brachycephalia, right-side neurologic soft signs, obsessive personality profile, low color-word interference effect in Stroop test, and diffuse increased cerebral blood flow during calculation task in 99mTc-ECD SPECT. MRI showed anatomical temporal plane inverse asymmetry. Evidence appears to support the hypothesis that savant skill is related to excessive and erroneous use of cognitive processing resources instigated by probable failure in central executive control mechanisms.

    An executive summary is presented of a preliminary study done on several potential High Energy Astronomy Observatory (HEAO) missions which are follow-on missions to the currently defined HEAO program. The purpose was to examine several typical missions and determine the relative complexities associated with them. The four payloads investigated were a 1.2 m Diameter x-ray Telescope observatory, a Large Area Moderate Angular Resolution (LAMAR) observatory, a cosmic ray observatory, and (4) a gamma ray observatory. Each of the four observatories was considered a national facility. Low cost approaches were stressed throughout, with considerable use of HEAO Block I experience and designs effected to provide a high degree of confidence that such approaches were achievable. The use of the Multi-Mission Spacecraft (MMS) and the HEAO Block I spacecraft was considered as a result of this low cost emphasis. Also, NASA standard components were considered, where applicable

    This executive summary for Section 5 of the "Advancing Dental Education in the 21 st Century" project addresses the current and future educational systems for dental assisting, dental hygiene, dental therapy, and dental laboratory technology. Nineteen experts prepared six background articles on the educational changes necessary for future roles and practices. The key issues addressed relate to delivery system changes, educational curricula, scopes of practice, regulatory measures, and the public's oral health. The major finding is that substantial reforms will be needed to adequately prepare allied oral health professionals for the changes anticipated in 2040. A reconsideration of current accreditation guidelines, more flexibility with scopes of practice, and an adherence to rigorous academic programs are essential elements for the future of these professions.

    2016-08-01

    Performing Failure Modes and Effect Analysis (FMEA) during software architecture design is becoming a basic requirement in an increasing number of domains; however, due to the lack of standardized early design phase model execution, classic SW-FMEA approaches carry significant risks and are human effort-intensive even in processes that use Model-Driven Engineering.Recently, modelling languages with standardized executable semantics have emerged. Building on earlier results, this paper describes framework support for generating executable error propagation models from such models during software architecture design. The approach carries the promise of increased precision, decreased risk and more automated execution for SW-FMEA during dependability- critical system development.

    Future NASA plans call for long-duration deep space missions with human crews. Because of light-time delay and other considerations, increased autonomy will be needed. This will necessitate integration of tools in such areas as anomaly detection, diagnosis, planning, and execution. In this paper we investigate an approach that integrates planning and execution by embedding planner-derived temporal constraints in an execution procedure. To avoid the need for propagation, we convert the temporal constraints to dispatchable form. We handle some uncertainty in the durations without it affecting the execution; larger variations may cause activities to be skipped.

    Embodiments relate to clustering execution in a processing system. An aspect includes accessing a control flow graph that defines a data dependency and an execution sequence of a plurality of tasks of an application that executes on a plurality of system components. The execution sequence of the tasks in the control flow graph is modified as a clustered control flow graph that clusters active and idle phases of a system component while maintaining the data dependency. The clustered control flow graph is sent to an operating system, where the operating system utilizes the clustered control flow graph for scheduling the tasks.

    2000-01-01

    Engineers are more and more faced to the hard problem of sophisticated real-time System whereas time to market becomes always smaller. Object oriented modeling supported by UML standard brings effective solutions to such problems. However the possibility to specify real-time aspects of an application are not yet fully satisfactory Indeed, existing industrial proposals supply good answers to concurrency specification problem but they are yet limited regarding to real-time quantitative properties specification of an application. This work aims to construct a complete and consistent UML methodology based on a profile dedicated to automotive embedded Systems modeling and prototyping. This profile contains ail needed extensions to express easily the real-time quantitative properties of an application. Moreover, thanks to the formalization of UML protocol state machines, real-time concepts have been well-integrated in the object oriented paradigm. The main result of this deep integration is that a user is now able to model real-time Systems through the classical object oriented view i.e. without needing any specific knowing in real-time area. In order to answer to an industrial requirement, Systems prototyping (key point for car industry) the ACCORD/UML approach allows also to build executable models of an application. For that purpose, the method supplies a set of rules allow.ng to remove UML ambiguous semantics points, to complete semantics variation points and then to obtain a complete and coherent global model of an application being executable. The work of UML extension and its using formalization realized all along this thesis supplied also a complete and non-ambiguous modeling framework for automotive electronics Systems development. This is also a base particularly well-suited to tackle other facets of the Systems development as automatic and optimized code generation, validation, simulation or tests. (author) [fr

    2012-01-01

    This Pu-238 Supply Program Project Execution Plan (PEP) summarizes critical information and processes necessary to manage the program. The PEP is the primary agreement regarding planning and objectives between The Department of Energy Office of Nuclear Energy (DOE NE-75), Oak Ridge National Laboratory Site Office (OSO) and the Oak Ridge National Laboratory (ORNL). The acquisition executive (AE) will approve the PEP. The PEP is a living document that will be reviewed and revised periodically until the project is complete. The purpose of the project is to reestablish the capability to produce plutonium-238 (Pu-238) domestically. This capability consists primarily of procedures, processes, and design information, not capital assets. As such, the project is not subject to the requirements of DOE O 413.3B, but it will be managed using the project management principles and best practices defined there. It is likely that some capital asset will need to be acquired to complete tasks within the project. As these are identified, project controls and related processes will be updated as necessary. Because the project at its initiation was envisioned to require significant capital assets, Critical Decision 0 (CD-0) was conducted in accordance with DOE O 413.3B, and the mission need was approved on December 9, 2003, by William Magwood IV, director of the Office of Nuclear Energy (NE), Science and Technology, DOE. No date was provided for project start-up at that time. This PEP is consistent with the strategy described in the June 2010 report to Congress, Start-up Plan for Plutonium-238 Production for Radioisotope Power Systems.

    The computer executive functional system design concepts derived from study of the Space Station/Base are presented. Information Management System hardware configuration as directly influencing the executive design is reviewed. The hardware configuration and generic executive design requirements are considered in detail in a previous report (System Configuration and Executive Requirements Specifications for Reusable Shuttle and Space Station/Base, 9/25/70). This report defines basic system primitives and delineates processes and process control. Supervisor states are considered for describing basic multiprogramming and multiprocessing systems. A high-level computer executive including control of scheduling, allocation of resources, system interactions, and real-time supervisory functions is defined. The description is oriented to provide a baseline for a functional simulation of the computer executive system.

    2011-01-01

    Full Text Available In this paper, the author analyses the issues of independence and rewarding members of supervisory boards and non-executive directors in administrative boards. The question of independence was developed as one of the fundamental issues of corporative administration. Members of these organs of society should have the appropriate qualifications, specific knowledge and skills in order to reasonably and impartially weigh up social business and reach decisions in the best interests of society, its members and other interest holders. So that they can act in accordance with this, the presumption is that they are independent. Recently, after financial crises, it is precisely the independence of supervisory members, that is, non-executive directors, which is considered to be the foundation of the fight against the opportunism of administration and main shareholders. The authors analyse the Recommendations on Independence and Executive Remuneration for members of supervisory and administrative boards of the European Union, together with their implementation in Croatian law and practice.

    From generation through analysis and collaboration to communication, scientific research requires the right tools. Scientists create their own software using third party libraries and platforms. Cloud computing, Open Science, public data infrastructures, and Open Source enable scientists with unprecedented opportunites, nowadays often in a field "Computational X" (e.g. computational seismology) or X-informatics (e.g. geoinformatics) [0]. This increases complexity and generates more innovation, e.g. Environmental Research Infrastructures (environmental RIs [1]). Researchers in Computational X write their software relying on both source code (e.g. from https://github.com) and binary libraries (e.g. from package managers such as APT, https://wiki.debian.org/Apt, or CRAN, https://cran.r-project.org/). They download data from domain specific (cf. https://re3data.org) or generic (e.g. https://zenodo.org) data repositories, and deploy computations remotely (e.g. European Open Science Cloud). The results themselves are archived, given persistent identifiers, connected to other works (e.g. using https://orcid.org/), and listed in metadata catalogues. A single researcher, intentionally or not, interacts with all sub-systems of RIs: data acquisition, data access, data processing, data curation, and community support [3]. To preserve computational research [3] proposes the Executable Research Compendium (ERC), a container format closing the gap of dependency preservation by encapsulating the runtime environment. ERCs and RIs can be integrated for different uses: (i) Coherence: ERC services validate completeness, integrity and results (ii) Metadata: ERCs connect the different parts of a piece of research and faciliate discovery (iii) Exchange and Preservation: ERC as usable building blocks are the shared and archived entity (iv) Self-consistency: ERCs remove dependence on ephemeral sources (v) Execution: ERC services create and execute a packaged analysis but integrate with

    Executive attention refers to the goal-directed control of attention. Existing models of executive attention distinguish between three correlated, but empirically dissociable, factors related to selectively attending to task-relevant stimuli (Selective Attention), inhibiting task-irrelevant responses (Response Inhibition), and actively maintaining goal-relevant information (Working Memory Capacity). In these models, Selective Attention and Response Inhibition are moderately strongly correlate...

  9. LQCD workflow execution framework: Models, provenance and fault-tolerance

    International Nuclear Information System (INIS)

    Piccoli, Luciano; Simone, James N; Kowalkowlski, James B; Dubey, Abhishek

    2010-01-01

    Large computing clusters used for scientific processing suffer from systemic failures when operated over long continuous periods for executing workflows. Diagnosing job problems and faults leading to eventual failures in this complex environment is difficult, specifically when the success of an entire workflow might be affected by a single job failure. In this paper, we introduce a model-based, hierarchical, reliable execution framework that encompass workflow specification, data provenance, execution tracking and online monitoring of each workflow task, also referred to as participants. The sequence of participants is described in an abstract parameterized view, which is translated into a concrete data dependency based sequence of participants with defined arguments. As participants belonging to a workflow are mapped onto machines and executed, periodic and on-demand monitoring of vital health parameters on allocated nodes is enabled according to pre-specified rules. These rules specify conditions that must be true pre-execution, during execution and post-execution. Monitoring information for each participant is propagated upwards through the reflex and healing architecture, which consists of a hierarchical network of decentralized fault management entities, called reflex engines. They are instantiated as state machines or timed automatons that change state and initiate reflexive mitigation action(s) upon occurrence of certain faults. We describe how this cluster reliability framework is combined with the workflow execution framework using formal rules and actions specified within a structure of first order predicate logic that enables a dynamic management design that reduces manual administrative workload, and increases cluster-productivity.

    Rodger Ll. Wood

    2017-10-01

    Full Text Available Objective: This article will address how anomalies of executive function after traumatic brain injury (TBI can translate into altered social behavior that has an impact on a person’s capacity to live safely and independently in the community.Method: Review of literature on executive and neurobehavioral function linked to cognitive ageing in neurologically healthy populations and late neurocognitive effects of serious TBI. Information was collated from internet searches involving MEDLINE, PubMed, PyscINFO and Google Scholar as well as the authors’ own catalogs.Conclusions: The conventional distinction between cognitive and emotional-behavioral sequelae of TBI is shown to be superficial in the light of increasing evidence that executive skills are critical for integrating and appraising environmental events in terms of cognitive, emotional and social significance. This is undertaken through multiple fronto-subcortical pathways within which it is possible to identify a predominantly dorsolateral network that subserves executive control of attention and cognition (so-called cold executive processes and orbito-frontal/ventro-medial pathways that underpin the hot executive skills that drive much of behavior in daily life. TBI frequently involves disruption to both sets of executive functions but research is increasingly demonstrating the role of hot executive deficits underpinning a wide range of neurobehavioral disorders that compromise relationships, functional independence and mental capacity in daily life.

    2014-03-01

    The current study tested the resource allocation hypothesis, examining whether baseline rumination or depressive symptom levels prospectively predicted deficits in executive functioning in an adolescent sample. The alternative to this hypothesis was also evaluated by testing whether lower initial levels of executive functioning predicted increases in rumination or depressive symptoms at follow-up. A community sample of 200 adolescents (ages 12-13) completed measures of depressive symptoms, rumination, and executive functioning at baseline and at a follow-up session approximately 15 months later. Adolescents with higher levels of baseline rumination displayed decreases in selective attention and attentional switching at follow-up. Rumination did not predict changes in working memory or sustained and divided attention. Depressive symptoms were not found to predict significant changes in executive functioning scores at follow-up. Baseline executive functioning was not associated with change in rumination or depression over time. Findings partially support the resource allocation hypothesis that engaging in ruminative thoughts consumes cognitive resources that would otherwise be allocated towards difficult tests of executive functioning. Support was not found for the alternative hypothesis that lower levels of initial executive functioning would predict increased rumination or depressive symptoms at follow-up. Our study is the first to find support for the resource allocation hypothesis using a longitudinal design and an adolescent sample. Findings highlight the potentially detrimental effects of rumination on executive functioning during early adolescence. Copyright © 2013 Elsevier Ltd. All rights reserved.

    2018-01-01

    Delays in the development of executive functioning skills are frequently observed in pediatric neuropsychology populations and can have a broad and significant impact on quality of life. As a result, assessment of executive functioning is often relevant for the development of formulations and recommendations in pediatric neuropsychology clinical work. Questionnaire-based measures of executive functioning behaviors in everyday life have unique advantages and complement traditional neuropsychological measures of executive functioning. Two case studies of children with spina bifida are presented to illustrate the clinical use of a new questionnaire measure of executive and learning-related functioning, the Learning, Executive, and Attention Functioning Scale (LEAF). The LEAF emphasizes clinical utility in assessment by incorporating four characteristics: brevity in administration, breadth of additional relevant content, efficiency of scoring and interpretation, and ease of availability for use. LEAF results were consistent with another executive functioning checklist in documenting everyday behavior problems related to working memory, planning, and organization while offering additional breadth of assessment of domains such as attention, processing speed, and novel problem-solving. These case study results demonstrate the clinical utility of questionnaire-based measurement of executive functioning in pediatric neuropsychology and provide a new measure for accomplishing this goal.

    2011-10-01

    Full Text Available The majority of startups fail to consider sales execution as part of their overall strategy. This article demonstrates how a sales execution strategy can help a company take a product or service to market more efficiently and effectively by focusing on the customers that are key to generating revenue. Combined with techniques for recruiting effectively and measuring sales outcomes, a sales execution strategy helps technology startups exceed growth aspirations and potentially reduce or even eliminate the requirement for external investment. In this article, we first describe the focus of assistance currently given to startups and the reasons why sales execution strategies are often overlooked. Next, we outline recommendations for developing, implementing, and supporting a sales execution strategy. Finally, we summarize the key points presented in the article.

    2014-01-01

    Objective We investigated the viability of psychometrically robust executive function measures as markers for premanifest Huntington’s disease (HD). Methods Fifteen premanifest HD subjects and 42 controls were compared on the NIH EXAMINER executive function battery. This battery yields an overall Executive Composite score, plus Working Memory, Cognitive Control, and Fluency Scores that are measured on psychometrically matched scales. The scores were correlated with two disease markers, disease burden and striatal volumes, in the premanifest HD subjects. Results The premanifest HD subjects scored significantly lower on the Working Memory Score. The Executive Composite positively correlated with striatal volumes, and Working Memory Score negatively correlated with disease burden. The Cognitive Control and Fluency Scores did not differ between the groups or correlate significantly with the disease markers. Conclusions The NIH EXAMINER Executive Composite and Working Memory Score are sensitive markers of cognitive dysfunction, striatal volume, and disease burden in premanifest HD. PMID:24375511

    Full Text Available É bem estabelecido que a respiração oral em crianças está relacionada à hipertrofia adenoamigdaliana, que é a principal causa de apneia do sono nesta população. Apesar da importância deste tema, há poucos estudos que comprovam a relação entre SAOS e respiração oral. OBJETIVO: Determinar a prevalência de distúrbios respiratórios do sono em crianças respiradoras orais e sua correlação com achados otorrinolaringológicos. MATERIAL E MÉTODO: Foram avaliados retrospectivamente 248 prontuários de crianças respiradoras orais do serviço de Otorrinolaringologia Pediátrica de uma grande instituição entre 2000 e 2006, analisando os achados otorrinolaringológicos, polissonografia, nasofibroscopia e/ou radiografia em perfil do Cavum. O principal dado polissonográfico utilizado foi o índice de apneia (IA. Classificou-se como ronco primário aqueles com IA1. Desenho Científico: Coorte retrospectivo. RESULTADOS: Dos 248 pacientes incluídos, 144 (58% apresentavam ronco primário e 104 (42% apresentavam SAOS.

Por medio de la medición de todos los árboles (d ≥ 10 cm, se identificaron botánicamente los ingresos en tres sitios de la Península de Osa (Estero Guerra, Dos Brazos de Río Rincón y Los Mogos, donde se instaló cuatro parcelas permanentes de muestreo (PPM de 1 ha, establecidas en el año 1990. En ese momento y, posteriormente, quince y diecinueve años (2007 y 2011, respectivamente, se analizó el estado del bosque primario después de aplicar cuatro sistemas de aprovechamiento forestal: Sistema de aprovechamiento con bueyes (SACB, Sistema de aprovechamiento mejorado (SATM, Sistema de aprovechamiento tradicional (SATT y Sistema de aprovechamiento bueyes- tractor, (SABT. El análisis de la dinámica del bosque se realizó con base en el crecimiento, tasas de mor talidad, de reclutamiento y de recambio. El incremento corriente anual (ICA promedio para el periodo evaluado varió de los 2,47 a los 3,56 mm/ año.El análisis estadístico mostró que el valor ICA presenta una distribución normal y homocedasticidad, y el análisis de varianza indica que no existen diferencias significativas entre los ICA de cada sistema de aprovechamiento (p = 0,3410. La tasa de mortalidad promedio para los cuatro sistemas de aprovechamiento es de 1,301% y la de reclutamiento de 1,869%, mientras que la tasa de recambio anual es de 0,569%. El análisis estadístico comprobó que las tasas de mortalidad, reclutamiento y recambio presentan una distribución normal y homocedasticidad, y, por su parte, el análisis de varianza mostró que las diferencias entre los aprovechamientos no son

    Full Text Available A pesar de la cantidad de ríos que tiene Costa Rica, la mayoría muestra algún grado de contaminación. Por lo tanto, resultan de particular interés aquellos que forman parte de la Gran Área Metropolitana, en donde se concentra el 70% de la población del país. Si bien la calidad del agua se puede determinar por medio del análisis de distintos indicadores, es ventajosa su simplificación por medio del uso de índices de calidad del agua. Uno de los índices adoptados en Costa Rica es el “Índice holandés de valoración de la calidad del agua” (ICA holandés, el cual se basa en el uso de tres indicadores: la demanda bioquímica de oxígeno, el nitrógeno amoniacal y el oxígeno disuelto, este último expresado como porcentaje de saturación de oxígeno. En el presente estudio se analizaron estos indicadores en diez ríos localizados en las provincias de San José, Alajuela, Heredia y Cartago, así como en la Península de Osa. Además, para correlacionar el ICA holandés con la densidad poblacional, se muestrearon tres puntos en cada río: la zona alta cercana a la naciente del río, la zona media y la zona baja, ubicada cerca de la desembocadura del río. Se encontró que los ríos que atraviesan las ciudades altamente densas, las cuales poseen densidades poblacionales superiores a los 8000 habitantes por kilómetro cuadrado (hab/km2, muestran niveles de contaminación en los ríos de “severa” a “muy severa”; por otra parte, lugares con densidades poblacionales entre los 3000-8000 hab/km2, en general, muestran niveles de contaminación de “moderada” a “severa”; mientras que los poblados con menos de 1000 hab/ km2 causan que la calidad de las aguas presente un nivel de contaminación de “incipiente” a “no contaminada”. Estos resultados pueden variar dependiendo del caudal de los ríos, su recorrido total y el uso que se le dé a la tierra. El análisis de Regresión Lineal Univariable mostró una correlaci

  11. Secure Execution of Distributed Session Programs

    Full Text Available The development of the SJ Framework for session-based distributed programming is part of recent and ongoing research into integrating session types and practical, real-world programming languages. SJ programs featuring session types (protocols are statically checked by the SJ compiler to verify the key property of communication safety, meaning that parties engaged in a session only communicate messages, including higher-order communications via session delegation, that are compatible with the message types expected by the recipient. This paper presents current work on security aspects of the SJ Framework. Firstly, we discuss our implementation experience from improving the SJ Runtime platform with security measures to protect and augment communication safety at runtime. We implement a transport component for secure session execution that uses a modified TLS connection with authentication based on the Secure Remote Password (SRP protocol. The key technical point is the delicate treatment of secure session delegation to counter a previous vulnerability. We find that the modular design of the SJ Runtime, based on the notion of an Abstract Transport for session communication, supports rapid extension to utilise additional transports whilst separating this concern from the application-level session programming task. In the second part of this abstract, we formally prove the target security properties by modelling the extended SJ delegation protocols in the pi-calculus.

  12. The physician executive in a changing world.

    Physicians are losing their historic franchise as sole and primary providers of medical care. In addition to eroding moral and scientific authority, physicians are also losing income and status. It is no wonder that physicians are retrenching--confused and angry about the increasing marginalization of their profession and about society's changing expectations. Physicians are caught in a transition zone between the world that was and the one that will soon be. This is destabilizing and causes great anxiety. Rather than being buffeted by changing social and cultural definitions of health care, physicians must become proactively involved in the future of their profession. Physicians can only do this by offering a better mental model of health, medicine, and the community. This cannot be a defensive retreat from engagement. Rather, it must be an imaginative vision, vigorously set forth--a vision that will enlist the support of all constituencies involved in the effort to improve the health and well-being of all members of our society. The physician executive needs to work with physicians to orchestrate this effort to create a new vision of health in the 21st century.

  15. Midline thalamic reuniens lesions improve executive behaviors.

    The role of the thalamus in complex cognitive behavior is a topic of increasing interest. Here we demonstrate that lesions of the nucleus reuniens (NRe), a midline thalamic nucleus interconnected with both hippocampal and prefrontal circuitry, lead to enhancement of executive behaviors typically associated with the prefrontal cortex. Rats were tested on four behavioral tasks: (1) the combined attention-memory (CAM) task, which simultaneously assessed attention to a visual target and memory for that target over a variable delay; (2) spatial memory using a radial arm maze, (3) discrimination and reversal learning using a touchscreen operant platform, and (4) decision-making with delayed outcomes. Following NRe lesions, the animals became more efficient in their performance, responding with shorter reaction times but also less impulsively than controls. This change, combined with a decrease in perseverative responses, led to focused attention in the CAM task and accelerated learning in the visual discrimination task. There were no observed changes in tasks involving either spatial memory or value-based decision making. These data complement ongoing efforts to understand the role of midline thalamic structures in human cognition, including the development of thalamic stimulation as a therapeutic strategy for acquired cognitive disabilities (Schiff, 2008; Mair et al., 2011), and point to the NRe as a potential target for clinical intervention.

    Ormen Lange is the largest natural gas field in development on the Norwegian continental shelf. This paper discussed Norsk Hydro's Ormen Lange development strategy and execution. Several illustrations of the Ormen Lange project were presented, including the field layout and the main challenges of working in deep water. Other challenges involve environmental conditions; long distance control; and hydrate prevention. Several components of the project were presented, including the xmas tree handling system; choke module; control system; large bore tie-in system; in-line tee system; and free spans in pipeline design. Other topics that were presented and illustrated included the feasibility of pipeline design; design optimization with installation contractors; design optimization between intervention methods; positioning; dredging with spiders; excavation with jetprops; ploughing; rock installation; and trenching. The installation of thirty inch pipelines and umbilical lines in shallow and deep water were also discussed and illustrated. The presentation concluded with a discussion of lessons learned subsea. These included early definition of operational requirements; close monitoring of interface work between contractors; professional change management; and thorough testing onshore prior to installation. Securing vessel capacity and timely start-up were among the lessons learned for marine operations. figs.

    The aim of this study was to investigate whether cognitive performance was a valid marker of overreaching. 10 well-trained male endurance athletes increased their training load by 100% for 2 weeks. They performed a maximal graded test, a constant speed test, a reaction time task and a computerized version of the Stroop color word-test before and after this overload period. Regarding performance results, five participants were considered as overreached and the five remaining were considered as well-trained. We found no significant differences between groups in performing the Stroop test. Noteworthy, we found a small increase in response time in the more complex condition in overreached athletes (1 188+/-261 to 1 297+/-231 ms, effect size=0.44), while it decreased moderately in the well-trained athletes (1 066+/-175 to 963+/-171 ms, effect size=-0.59). Furthermore, we found an interaction between time and group on initiation time of the reaction time task, since it increased in overreached athletes after the overload period (246+/-24 to 264+/-26 ms, p<0.05), while it remained unchanged in well-trained participants. Participants made very few anticipation errors, whatever the group or the period (error rate <2%).We concluded that an unaccustomed increase in training volume which is accompanied by a decrement in physical performance induces a deterioration of some executive functions.

    The present work is aimed at analysing executive function (EF) in adolescents with Down Syndrome (DS). So far, EF has been analysed mainly in adults with DS, showing a pattern of impairment. However, less is known about children and adolescents with this syndrome. Studying adolescents with DS might help us better understand whether performances on EF tasks of individuals with DS are determined by age or by Alzheimer disease, as some studies suggest, or whether their performances are directly related to DS cognitive profile. A battery of EF tasks assessing set shifting, planning/problem-solving, working memory, inhibition/perseveration and fluency, as well as a tasks assessing sustained attention has been administered to a group of 15 adolescents with DS and 15 typically developing children matched for mental age. All EF tasks were selected from previous studies with individuals with intellectual disabilities or from developmental literature and are thought to be useful for the samples considered. The present results revealed that the group of individuals with DS performed at a significantly lower level on tasks assessing set shifting, planning/problem-solving, working memory and inhibition/perseveration, but not on the tasks assessing fluency. In addition, individuals with DS demonstrated a greater number of errors and less strategy use for the sustained attention task. The results suggest a broad impairment in EF in adolescents with DS, and are consistent with several similar studies conducted with adults with DS. We assume that EF deficit is a characteristic of DS.

    This report provides an executive summary of the Cryofracture demonstration program performed at Nuclear Remedial Technologies Corporation under contract to EG ampersand G Idaho, Inc., for the Department of Energy (DOE). Cryofracture is a size-reducing process whereby objects are frozen whereby objects are frozen to liquid nitrogen temperatures and crushed in a large hydraulic press. Material at the cryogenic temperatures have low ductility and are easily size reduced by fracturing. The main application being investigated for the DOE is for retrieved buried and stored transuranic (TRU) waste. Six 55-gallon drums and six 2 ft x 2 ft x 8 ft boxes containing simulated waste with tracers were subjected to the Cryofracture process. Data was obtained on (a) cool-down time, (b) yield strength of the containers, (c) size distribution of the waste before and after the Cryofracture process, (d) volume reduction of the waste, and (e) sampling of air and surface dusts for spread of tracers to evaluate potential contamination spread. The Cryofracture process was compared to conventional shredders and detailed cost estimates were established for construction of a Cryofracture facility at the Idaho National Engineering Laboratory. Although cost estimates for conventional shredding are higher for Cryofracture, the potential for fire and explosion during conventional shredding would incur additional costs to preclude these events. These additional costs are unknown and would require considerable research and development. 4 refs., 6 figs., 7 tabs
