    LightLeaves is an installation combining leaf shaped, white light reflection holograms of landscape images with a special kinetic lighting device that houses a lamp and moving leaf shaped masks. The masks are controlled by an Arduino microcontroller and servomotors that position the masks in front of the illumination source of the holograms. The work is the most recent in a long series of landscapes that combine multi-hologram installations with computer controlled devices that play with the motion of the holograms, the light, sound or other elements in the work. LightLeaves was first exhibited at the Peabody Essex Museum in Salem, Massachusetts in a show titled E ye Spy: Playing with Perception .

    Given the limited studies on emergency care management, this study aimed to explore the relationships of emergency department (ED) culture values to certain dimensions of ED physicians' and nurses' work satisfaction and intent to leave. Four hundred and forty-two emergency medical professionals completed the employee satisfaction questionnaire across 119 hospital-based EDs, which had culture value evaluations filed, were used as unit of analysis in this study. Adjusting the personal and employment backgrounds, and the surrounded EDs' unit characteristics and environmental factors, multiple regression analyses revealed that clan and market cultures were related to emergency physicians' work satisfaction and intent to leave. On the other hand, adhocracy, market and hierarchical cultures were related to emergency nurses' work satisfaction. There do exist different patterns among various culture types on various work satisfaction dimensions and intent to leave of emergency physicians and nurses. The findings could offer hospital and ED leaders insights for changes or for building a better atmosphere to enhance the work life of emergency physicians and nurses.

    Full Text Available Individuals of Marsilea quadrifolia, an amphibious fern, experiencing extreme variation in environment develop heterophyll. In this study, we compared stomatal and trichome density on upper and lower surfaces, leaf and petiole area mass ratio, spectral properties and photosynthetic performance of floating, emergent and terrestrial leaves of M. quadrifolia, to explore the ecological advantages of producing different leaf types. Morphological measurement reveals that these three types of leaf display highly differences in stomatal density on lower epidermis, trichome density on both surfaces and petiole dry mass per length, and reflectance coefficient between 500 and 650 nm. In contrast, no significant difference was found in the PSII electron transport rate of the three types of leaves. The analysis of stable carbon isotope ratio of the three types of leaves indicates that they all use C3 photosynthetic pathway.

    In some tea tree planting areas within 300 km from the TEPCO's Fukushima Daiichi Nuclear Power Plant (FNPP), it was found that newly emerged tea plant leaves for green tea contained two radiocesium species (cesium-134 and cesium-137). In this study, using processed green tea leaves for drinking, extraction ratios of radiocesium under several brew conditions were observed. When 90 deg C water was used, 50-70% of radiocesium was extracted into the water, while 54-60% of radiocesium was extracted with 60 deg C water. A part of radiocesium would be removed from leaves if the leaves were washed with 20 and 60 deg C water before brewing, and the efficiencies were 11 and 32%, respectively. Newly emerged camellia leaves were used to simulate the radiocesium removal ratio from raw tea leaves by washing and boiling; radioactivity concentration was decreased to 60% of the original concentration with washing and 10 min boiling. From these results, it was found that almost half of the radiocesium would not be removed from raw or processed tea leaves. The values obtained in the present study could be used for internal radiation dose estimation from tea leaves. (author)

    An accident occurred at the Fukushima Dai-ichi Nuclear Power Plant in March 2011 at which time large amounts of radionuclides were released into the atmosphere and the sea. In early May 2011, it was found that newly emerged tea (Camellia sinensis) leaves contained radiocesium, both 134 Cs and 137 Cs in some areas more than 300 km away from the Fukushima plant. To understand the mechanisms of radiocesium transfer to newly emerged tissues (shoots, leaves and fruits) of other plants in the future, radiocesium concentrations in newly emerged leaves of 14 plant species collected from the sampling areas in and near National Institute of Radiological Sciences in Chiba, Japan. The studied plant types were: (1) herbaceous plants, (2) woody plants with no old leaves at the time of the March accident, and (3) woody plants with old leaves out before the accident. About 40–50 d after the start of the accident, newly emerged leaves from woody plant with old leaves tended to show higher values than other woody or herbaceous plants. Concentrations of radiocesium in newly emerged tissues of trees decreased with time, but they did not decrease to the level of herbaceous plants. The type of the plant and presence of old leaves at the time of the heavy deposition period affected the radiocesium concentrations in newly emerged tissues.

    To determine whether the intent of career mobility is associated with the frequency of job stressors and burnout syndrome experienced by emergency nurses. to assess perceived frequency of job stressors and burnout syndrome prevalence and its possible association with demographic and occupational values of the sample analyzed. We performed a cross-sectional study. We used a survey of sociodemographic and occupational variables, and two validated questionnaires: the "Nursing Stress Scale" validated by Escriba et al. (1999) and the Inventory to assess Burnout Syndrome (MBI-GS, Schaufeli et al., 1996). The total Stress score mean was 32.88 +/- 12.67. There was a Burnout prevalence of 2.34%, while 23.4% of the sample expressed high levels of cynicism/depersonalization. The frequency of job stressors was significantly associated with burnout syndrome dimensions. The frequency of stressors and intention of career mobility were significant predictors of emotional exhaustion and cynicism, while the fixed night shift was associated with lower professional efficacy. This study shows a moderate frequency of job stressors in the unit analyzed, and a low prevalence of Burnout Syndrome. The intention to leave or career mobility is an important predictor of burnout process, so it should be something to take into account by human resource managers, in order to prevent the development of the burnout process in health organizations.

    To identify the relationship between emergency nurses' intention to leave the hospital and their coping methods following workplace violence. Emergency departments report a high prevalence of workplace violence, with nurses being at particular risk of violence from patients and patients' relatives. Violence negatively influences nurses' personal and professional lives and increases their turnover. This is a cross-sectional, descriptive survey study. Participants were nurses (n = 214) with over one year of experience of working in an emergency department. We measured workplace violence, coping after workplace violence experiences and job satisfaction using scales validated through a preliminary survey. Questionnaires were distributed to all nurses who signed informed consent forms. Multiple logistic regression analysis was used to identify the relationships between nurses' intention to leave the hospital and their coping methods after workplace violence. Verbal abuse was the most frequent violence experience and more often originated from patients' relatives than from patients. Of the nurses who experienced violence, 61.0% considered leaving the hospital. As for coping, nurses who employed problem-focused coping most frequently sought to identify the problems that cause violence, while nurses who employed emotion-focused coping primarily attempted to endure the situation. The multiple logistic regression analysis revealed that female sex, emotion-focused coping and job satisfaction were significantly related to emergency nurses' intention to leave. Emotion-focused coping seems to have a stronger effect on intention to leave after experiencing violence than does job satisfaction. Nurse managers should begin providing emergency nurses with useful information to guide their management of violence experiences. Nurse managers should also encourage nurses to report violent experiences to the administrative department rather than resorting to emotion-focused coping

    The objective was to identify predictive factors and outcomes associated with patients who leave emergency departments (EDs) without being seen in Victoria, Australia. This was a retrospective observational study of Victorian ED patient visits between July 1, 2000, and June 30, 2005, using linked hospital, ED, and death registration data. Index ED visits were identified for patients who left without being seen (LWBS) and for those who completed ED treatment and were discharged home. Statistical analyses included a general description and univariate analysis of patient, ED visit, temporal, and hospital-level factors. Logistic regression models were developed to assess risk factors associated with LWBS status compared to patients who completed treatment, to assess 48 hour re-presentations to ED; 48-hour hospital admissions; and 2-,7-, and 30-day mortality among those who LWBS compared to those who completed treatment. Adjusted odds ratios (ORs) and 99% confidence intervals (CIs) are presented. There were 239,305 LWBS episodes, for 205,500 patients over the 5-year period. Independent factors associated with LWBS patients in comparison to those who completed treatment include patients who are younger (15 to 24 years, OR = 2.46, 99% CI = 2.37 to 2.56), male (OR = 1.07, 99% CI = 1.05 to 1.08), of Australian indigenous background (OR = 1.63, 99% CI = 1.53 to 1.73), of non-English-speaking background (OR = 1.08, 99% CI = 1.06 to 1.10), noncompensable status (OR = 1.73, 99% CI = 1.68 to 1.79), self-referring (OR = 1.46, 99% CI = 1.43 to 1.49), nonassisted arrival mode (OR = 1.35, 99% CI = 1.30 to 1.40), and those with a hospital admission in the 12 months before the ED presentation (OR = 1.53, 99% CI = 1.51 to 1.55). Patients who LWBS had triage categories of lower urgency (nonurgent, OR = 8.21, 99% CI = 8.00 to 8.43), attended during the evening (OR = 1.10, 99% CI = 1.08 to 1.12), on either Sunday (OR = 1.20, 99% CI = 1.18 to 1.23) or Monday (OR = 1.20, 99% CI = 1.17 to 1

    The primary purpose of this study was to characterize job satisfaction with opportunities for advancement, job satisfaction with pay and benefits, and intent to leave the EMS profession among Nationally Registered EMT-Basics and EMT-Paramedics. A secondary data analysis was performed on the National Registry of EMTs Longitudinal Emergency Medical Technician Attributes and Demographic Study Project (LEADS) 2005 core survey. We used chi-square and multiple logistic regression analyses to test for differences in job satisfaction with opportunities for advancement, job satisfaction with pay and benefits, and intent to leave the EMS profession across years of experience and work location. Among 11 measures of job satisfaction, NREMT-Basics and NREMT-Paramedics were least satisfied with opportunities for advancement and pay and benefits (67.8 and 55.2%, respectively). Nearly 6% of respondents reported intentions of leaving the profession within 12 months. In univariate analyses, job satisfaction with advancement opportunities varied across years of experience and work location. Job satisfaction with pay and benefits varied across years of experience and work location. The proportion reporting intentions of leaving the profession did not vary across the two independent variables of interest. In multivariable logistic regression, statistical differences observed in univariate analyses were attenuated to non-significance across all outcome models. Income, personal health, level of EMS certification, and type of EMS work were significant in several outcome models. EMS workforce research is at its infancy, thus our study adds to a limited but growing body of knowledge. In future and replicated research, one will need to consider different person and organizational variables in predicting different measures of job satisfaction among EMS personnel.

    In this work, an analytical method, based on sonication-assisted extraction, clean-up by dispersive solid-phase extraction and determination by liquid chromatography-tandem mass spectrometry, has been developed and validated for the simultaneous determination of 15 emerging pollutants in leaves from four ornamental tree species. Target compounds include perfluorinated organic compounds, plasticizers, surfactants, brominated flame retardant, and preservatives. The method was optimized using Box-Behnken statistical experimental design with response surface methodology and validated in terms of recovery, accuracy, precision, and method detection and quantification limits. Quantification of target compounds was carried out using matrix-matched calibration curves. The highest recoveries were achieved for the perfluorinated organic compounds (mean values up to 87%) and preservatives (up to 88%). The lowest recoveries were achieved for plasticizers (51%) and brominated flame retardant (63%). Method detection and quantification limits were in the ranges 0.01-0.09 ng/g dry matter (dm) and 0.02-0.30 ng/g dm, respectively, for most of the target compounds. The method was successfully applied to the determination of the target compounds on leaves from four tree species used as urban ornamental trees (Citrus aurantium, Celtis australis, Platanus hispanica, and Jacaranda mimosifolia).

    The purpose of our study was to investigate the importance of different items as reasons for leaving the Emergency Medical Service (EMS) profession. An exit survey was returned by three distinct EMS samples: 127 full compensated, 45 partially compensated and 72 non-compensated/volunteer respondents, who rated the importance of 17 different items for affecting their decision to leave EMS. Unfortunately, there were a high percentage of "not applicable" responses for 10 items. We focused on those seven items that had a majority of useable responses across the three samples. Results showed that the desire for better pay and benefits was a more important reason for leaving EMS for the partially compensated versus fully compensated respondents. Perceived lack of advancement opportunity was a more important reason for leaving for the partially compensated and volunteer groups versus the fully compensated group. Study limitations are discussed and suggestions for future research offered.

    This study examined the influence of race and language on leaving the emergency department (ED) without complete evaluation and treatment (LWCET). This retrospective, case-cohort study examined LWCET among patients discharged home from 2 EDs between March 2, 2009, and March 31, 2010. Race and language were obtained by family self-report. We also explored wait time to see a physician as an explanation of racial disparities. One thousand two hundred eighty-five (1.7%) of 76,931 ED encounters ended in LWCET. Factors increasing LWCET were high ED activity, low acuity, and medical assistance (MA) insurance. American Indian, biracial, African American, and Hispanic races were also associated with higher odds of LWCET among visits by MA insurance patients compared with those of white patients on private insurance. Restricting the analysis to visits by MA insurance patients, only American Indian race was associated with LWCET compared with white race. Visits by patients using an interpreter or speaking a language other than English at home had lower odds of ending in LWCET. Sensitivity analyses in subgroups confirmed these findings. We developed a measure of ED activity that correlated well with wait time to see a physician (correlation coefficient = 0.993; P language, and insurance status interact to form a complex relationship with LWCET. Medical assistance insurance status appears to account for much of the excessive instances of LWCET seen in nonwhites. After restricting the analysis to MA insurance patients, only visits by American Indian patients had higher odds of LWCET compared with whites on MA insurance. Wait time to see a physician did not explain racial differences in LWCET.

    Full Text Available The objective of this study was to develop an agent based modeling (ABM framework to simulate the behavior of patients who leave a public hospital emergency department (ED without being seen (LWBS. In doing so, the study complements computer modeling and cellular automata (CA techniques to simulate the behavior of patients in an ED. After verifying and validating the model by comparing it with data from a real case study, the significance of four preventive policies including increasing number of triage nurses, fast-track treatment, increasing the waiting room capacity and reducing treatment time were investigated by utilizing ordinary least squares regression. After applying the preventing policies in ED, an average of 42.14% reduction in the number of patients who leave without being seen and 6.05% reduction in the average length of stay (LOS of patients was reported. This study is the first to apply CA in an ED simulation. Comparing the average LOS before and after applying CA with actual times from emergency department information system showed an 11% improvement. The simulation results indicated that the most effective approach to reduce the rate of LWBS is applying fast-track treatment. The ABM approach represents a flexible tool that can be constructed to reflect any given environment. It is also a support system for decision-makers to assess the relative impact of control strategies.

  1. Taking Leave?

    2000-01-01

    Planning a holiday? Then if you're a member of the personnel, you'll need to use the Laboratory's new leave system that will be put in place on 1 October. Leave allocations don't change - you are entitled to just as much holiday as before - but instead of being credited annually, your leave will be credited on a monthly basis, and this information will be communicated on your salary slip. The reason for the change is that with the various new leave schemes such as Recruitment by Saved Leave (RSL) and the Progressive Retirement Programme (PRP), a streamlined procedure was required for dealing with all kinds of leave. In the new system, each member of the personnel will have leave accounts to which leave will be credited monthly from the payroll and debited each time an absence is registered in the CERN Electronic Document Handling system (EDH). Leave balances will appear on monthly pay slips, and full details of leave transactions and balances will be available through EDH at all times. As the leave will be c...

    When managed conservatively, lateral epicondylitis often subsides only after considerable time, during which social and occupational activities are severely disrupted. If conservative management fails, a recently introduced option is arthroscopic release of the extensor carpi radialis brevis (ECRB). The primary objective of this study was to compare clinical outcomes of this procedure according to preoperative symptom duration. Earlier arthroscopic release is associated with better functional outcomes. Consecutive patients with arthroscopically managed lateral epicondylitis were included in a retrospective study. Arthroscopy was performed only after at least 6 months of conservative treatment. The criteria to evaluate the clinical outcomes were the Nirschl and Quick-DASH scores, muscle strength, time to pain relief, and percentage of functional recovery. Thirty-five patients were evaluated at a median of 4 years (range: 1-12 years) after surgery. Mean preoperative symptom duration was 18 months (range: 6-106 months) with a mean sick leave duration of 2.3±4.9 months. Postoperatively, mean time to recovery was 37.5 days (range: 7 days to 5 years) and mean sick leave duration was 2.4±2.4 months. The mean Quick-DASH score was 15.9±19.1. The Nirschl score improved significantly, from 26.4±7.9 to 66.3±16.3. The initial muscle strength deficit was 10.1±33.2% and muscle strength at last follow-up was increased by 4.3±30.3%. Symptom duration showed no correlations with any of the clinical outcome measures. Outcomes after arthroscopic release were not associated with symptom duration in this study. Nevertheless, the good clinical outcomes support treatment with arthroscopic release after only 6 months of conservative management. IV, retrospective study. Copyright © 2016.

    2011-01-01

    An exit survey was returned by a sample of 127 respondents in fully compensated positions who left the EMS profession, most within 12 months prior to filling out the exit survey. A very high percentage continued to work after leaving EMS. Respondents were asked to rate the importance of each of 17 items in affecting their decision to leave EMS. A higher than anticipated response to a "not applicable" response choice affected the usability of 8 of these items. Nine of the 17 items had at least 65 useable responses and were used for further analysis. Within these 9, stress/burnout and lack of job challenges had the highest importance in affecting the decision to leave EMS, while desire for better pay and benefits had the lowest importance. Desire for career change was positively related to life satisfaction after leaving EMS and negatively related to likelihood of returning to EMS. Stress/burnout was positively related to life satisfaction after leaving EMS. Study limitations and future research issues are briefly discussed.

  4. An earlier origin for the Acheulian.

    The Acheulian is one of the first defined prehistoric techno-complexes and is characterized by shaped bifacial stone tools. It probably originated in Africa, spreading to Europe and Asia perhaps as early as ∼1 million years (Myr) ago. The origin of the Acheulian is thought to have closely coincided with major changes in human brain evolution, allowing for further technological developments. Nonetheless, the emergence of the Acheulian remains unclear because well-dated sites older than 1.4 Myr ago are scarce. Here we report on the lithic assemblage and geological context for the Kokiselei 4 archaeological site from the Nachukui formation (West Turkana, Kenya) that bears characteristic early Acheulian tools and pushes the first appearance datum for this stone-age technology back to 1.76 Myr ago. Moreover, co-occurrence of Oldowan and Acheulian artefacts at the Kokiselei site complex indicates that the two technologies are not mutually exclusive time-successive components of an evolving cultural lineage, and suggests that the Acheulian was either imported from another location yet to be identified or originated from Oldowan hominins at this vicinity. In either case, the Acheulian did not accompany the first human dispersal from Africa despite being available at the time. This may indicate that multiple groups of hominins distinguished by separate stone-tool-making behaviours and dispersal strategies coexisted in Africa at 1.76 Myr ago.

    This study examined the effects of leaving home and going to college on changes in the frequency of alcohol use, heavy episodic drinking, and marijuana use shortly after leaving high school. We also examined how protective factors in late adolescence predict post-high school substance use and moderate the effects of leaving home and going to college. Data came from subjects (N = 319; 53% male) interviewed at the end of 12th grade and again approximately 6 months later, as part of the Raising Healthy Children project. Leaving home and going to college were significantly related to increases in the frequency of alcohol use and heavy episodic drinking from high school to emerging adulthood but not to changes in marijuana use. Having fewer friends who used each substance protected against increases in the frequency of alcohol use, heavy episodic drinking, and marijuana use. Higher religiosity protected against increases in alcohol-and marijuana-use frequency. Higher parental monitoring protected against increases in heavy episodic drinking and moderated the effect of going to college on marijuana use. Lower sensation seeking lessened the effect of going to college on increases in alcohol use and heavy episodic drinking. To prevent increases in substance use in emerging adulthood, interventions should concentrate on strengthening prosocial involvement and parental monitoring during high school. In addition, youths with high sensation seeking might be targeted for added intervention.

    A childhood history of attention deficit hyperactivity disorder (ADHD) is common in psychotic disorders, yet prescription stimulants may interact adversely with the physiology of these disorders. Specifically, exposure to stimulants leads to long-term increases in dopamine release. We therefore hypothesized that individuals with psychotic disorders previously exposed to prescription stimulants will have an earlier onset of psychosis. Age of onset of psychosis (AOP) was compared in individuals with and without prior exposure to prescription stimulants while controlling for potential confounding factors. In a sample of 205 patients recruited from an inpatient psychiatric unit, 40% (n = 82) reported use of stimulants prior to the onset of psychosis. Most participants were prescribed stimulants during childhood or adolescence for a diagnosis of ADHD. AOP was significantly earlier in those exposed to stimulants (20.5 vs. 24.6 years stimulants vs. no stimulants, p drugs of abuse, and family history of a first-degree relative with psychosis, the association between stimulant exposure and earlier AOP remained significant. There was a significant gender × stimulant interaction with a greater reduction in AOP for females, whereas the smaller effect of stimulant use on AOP in males did not reach statistical significance. In conclusion, individuals with psychotic disorders exposed to prescription stimulants had an earlier onset of psychosis, and this relationship did not appear to be mediated by IQ or cannabis.

    The observed decline of spring dust storms in Northeast Asia since the 1950s has been attributed to surface wind stilling. However, spring vegetation growth could also restrain dust storms through accumulating aboveground biomass and increasing surface roughness. To investigate the impacts of vegetation spring growth on dust storms, we examine the relationships between recorded spring dust storm outbreaks and satellite-derived vegetation green-up date in Inner Mongolia, Northern China from 1982 to 2008. We find a significant dampening effect of advanced vegetation growth on spring dust storms (r = 0.49, p = 0.01), with a one-day earlier green-up date corresponding to a decrease in annual spring dust storm outbreaks by 3%. Moreover, the higher correlation (r = 0.55, p storm outbreak ratio (the ratio of dust storm outbreaks to times of strong wind events) indicates that such effect is independent of changes in surface wind. Spatially, a negative correlation is detected between areas with advanced green-up dates and regional annual spring dust storms (r = -0.49, p = 0.01). This new insight is valuable for understanding dust storms dynamics under the changing climate. Our findings suggest that dust storms in Inner Mongolia will be further mitigated by the projected earlier vegetation green-up in the warming world.

  13. Alcoholism. Earlier diagnosis and definition of the problem.

    Science.gov (United States)

    Girard, D E; Carlton, B E

    1978-07-01

    There are important measurements of alcoholism that are poorly understood by physicians. Professional attitudes toward alcoholic patients are often counterproductive. Americans spend about $30 billion on alcohol a year and most adults drink alcohol. Even though traditional criteria allow for recognition of the disease, diagnosis is often made late in the natural course, when intervention fails. Alcoholism is a major health problem and accounts for 10 percent of total health care costs. Still, this country's 10 million adult alcoholics come from a pool of heavy drinkers with well defined demographic characteristics. These social, cultural and familial traits, along with subtle signs of addiction, allow for earlier diagnosis. Although these factors alone do not establish a diagnosis of alcoholism, they should alert a physician that significant disease may be imminent. Focus must be directed to these aspects of alcoholism if containment of the problem is expected.

    Full Text Available The late detection of the kick (the entrance of underground fluids into oil wells leads to oil well blowouts. It causes human life loss and imposes a great deal of expenses on the petroleum industry. This paper presents the application of adaptive neuro-fuzzy inference system designed for an earlier kick detection using measurable drilling parameters. In order to generate the initial fuzzy inference system, subtractive clustering is utilized. The training set contains 50 data samples and there are 362 data samples for testing the proposed method. Also, ANFIS structure is examined at different radii (the parameter of subtractive clustering. Different conformations are tested to get the earliest detection and the lowest false alarms while facing kick. Eventually, ANFIS verifies the danger exposure depth of about 28.6 meters before the depth that the kick was sensed by crew. Such an assessment gives the rig crew enough time to prepare for the danger and stop the operation before being exposed to high pressure zones.

    Untreated hypovolemia results in impaired outcome. This study tests our hypothesis whether general hemodynamic parameters detect acute blood loss earlier than monitoring parameters of regional tissue beds. Eight pigs (23-25 kg) were anesthetized and mechanically ventilated. A pulmonary artery catheter and an arterial catheter were inserted. Tissue oxygen tension was measured with Clark-type electrodes in the jejunal and colonic wall, in the liver, and subcutaneously. Jejunal microcirculation was assessed by laser Doppler flowmetry (LDF). Intravascular volume was optimized using difference in pulse pressure (dPP) to keep dPP below 13%. Sixty minutes after preparation, baseline measurements were taken. At first, 5% of total blood volume was withdrawn, followed by another 5% increment, and then in 10% increments until death. After withdrawal of 5% of estimated blood volume, dPP increased from 6.1% +/- 3.0% to 20.8% +/- 2.7% (P < 0.01). Mean arterial pressure (MAP), mean pulmonary artery pressure (PAP) and pulmonary artery occlusion pressure (PAOP) decreased with a blood loss of 10% (P < 0.01). Cardiac output (CO) changed after a blood loss of 20% (P < 0.05). Tissue oxygen tension in central organs, and blood flow in the jejunal muscularis decreased (P < 0.05) after a blood loss of 20%. Tissue oxygen tension in the skin, and jejunal mucosa blood flow decreased (P < 0.05) after a blood loss of 40% and 50%, respectively. In this hemorrhagic pig model systemic hemodynamic parameters were more sensitive to detect acute hypovolemia than tissue oxygen tension measurements or jejunal LDF measurements. Acute blood loss was detected first by dPP. Copyright (c) 2010 Elsevier Inc. All rights reserved.

    Imaging Mass Spectroscopy (IMS) is a unique research tool providing localization and identification of a wide range of biomolecules as essential data to understand biochemical processes in living organisms. Secondary Ion Mass Spectrometry with high-energy heavy ions (MeV-SIMS) is emerging as a promising IMS technique for chemical imaging of biological tissue. We measured the molecular mass spatial distributions in leaves of khat (Catha edulis). Khat is a natural drug plant, native to eastern Africa and the Arabian Peninsula. In these countries, fresh leaves are being chewed by significant part of population. It was reported that 80% of the adult population in Yemen chew the khat leaves. The main stimulating effects of khat are induced by a monoamine alkaloid called cathinone. During leaf ageing, cathinone is further metabolised to cathine and norephedrine. Earlier studies identified the alkaloids in khat, however little is known on their spatial distribution, reflecting the biosynthesis and accumulation in the tissue. Chemical mapping of alkaloids on cross-sections of khat leaves by MeV-SIMS was done at JSI by a pulsed 5.8 MeV 35Cl6+ beam, focused to a diameter of 15 μm, using a linear time-of-flight (TOF) spectrometer with a mass resolution of 500. In addition, measurements of MeV-SIMS mass spectra were performed at Kyoto University by a continuous broad beam of 6 MeV 63Cu4+ ions at an orthogonal TOF spectrometer with a high mass resolution of 11,000. Sections of leaves were analysed and mass spectra obtained at both MeV-SIMS setups were compared. Tissue-level distributions of detected alkaloids are presented and discussed.

    Abstract Over recent years many European Union countries have made changes to the design of the maternity leave provision. These policy developments reflect calls for greater gender equality in the workforce and more equal share of childcare responsibilities. However, while research shows that long period of leave can have negative effects on women's labour market attachment and career advancements, early return to work can be seen as a factor preventing exclusive breastfeeding, and therefore, potentially having negative health impacts for babies. Indeed, the World Health Organisation recommends exclusive breastfeeding up to 6 months of age to provide babies with the nutrition for healthy growth and brain development, protection from life-threatening ailments, obesity and non-communicable diseases such as asthma and diabetes. Therefore, labour market demands on women may be at odds with the health benefits for children gained by longer periods of maternity leave. The aim of this article is to examine the relationship between leave provision and health benefits for children. We examine maternity and parental leave provision across European countries and its potential impact on the breastfeeding of very young babies (up to 6-months of age). We also consider economic factors of potential extension of maternity leave provision to 6 months, such as costs to businesses, effects on the female labour market attachment, and wider consequences (benefits and costs) for individuals, families, employers and the wider society.

    Highlights: ► Sheshi female and male date palm leaves were treated with NaOH concentrations. ► Male leaves have lower mechanical properties and improved when treated by NaOH 2%. ► Female leaves have higher thermal stability. ► There are different properties for different types of date leaves. ► Leaves can be used as reinforcements for thermoplastic materials. -- Abstract: This paper describes the characterization of male and female date palm leaves from two different cultivars, Sheshi female and unknown male leaves. Characterization was done for both untreated and NaOH treated date palm leaves by infrared spectroscopy, thermogravimetric analysis and scanning electron microscopic techniques. To our knowledge, the difference in specious reaction to the treatment type of date palm fiber has not been investigated earlier. These leaves were treated with different concentrations of NaOH, 0.5%, 1%, 2% and 5% (w/w). The results from this investigation indicate that female leaves have better tensile properties which deteriorate with the increase of the alkali. The male leaves have lower tensile properties than female leaves and their mechanical properties are improved slightly by NaOH treatment. Female leaves have more pores than male leaves, this was proved and calculated by image analysis. Untreated female leaves have higher thermal stability (353 °C) than male leaves (343 °C). Both can be used as reinforcements in thermoplastic matrix materials whose processing temperatures are below 300 °C.

  5. Earlier reperfusion in patients with ST-elevation Myocardial infarction by use of helicopter

    2012-01-01

    Background In patients with ST-elevation myocardial infarction (STEMI) reperfusion therapy should be initiated as soon as possible. This study evaluated whether use of a helicopter for transportation of patients is associated with earlier initiation of reperfusion therapy. Material and methods A prospective study was conducted, including patients with STEMI and symptom duration less than 12 hours, who had primary percutaneous coronary intervention (PPCI) performed at Aarhus University Hospital in Skejby. Patients with a health care system delay (time from emergency call to first coronary intervention) of more than 360 minutes were excluded. The study period ran from 1.1.2011 until 31.12.2011. A Western Denmark Helicopter Emergency Medical Service (HEMS) project was initiated 1.6.2011 for transportation of patients with time-critical illnesses, including STEMI. Results The study population comprised 398 patients, of whom 376 were transported by ambulance Emergency Medical Service (EMS) and 22 by HEMS. Field-triage directly to the PCI-center was used in 338 of patients. The median system delay was 94 minutes among those field-triaged, and 168 minutes among those initially admitted to a local hospital. Patients transported by EMS and field-triaged were stratified into four groups according to transport distance from the scene of event to the PCI-center: ≤25 km., 26–50 km., 51–75 km. and > 75 km. For these groups, the median system delay was 78, 89, 99, and 141 minutes. Among patients transported by HEMS and field-triaged the estimated median transport distance by ground transportation was 115 km, and the observed system delay was 107 minutes. Based on second order polynomial regression, it was estimated that patients with a transport distance of >60 km to the PCI-center may benefit from helicopter transportation, and that transportation by helicopter is associated with a system delay of less than 120 minutes even at a transport distance up to 150 km

    In the Arctic, earlier snowmelt and longer growing seasons due to warming have been hypothesized to increase vegetation productivity. Using the Normalized Difference Vegetation Index (NDVI) from both field and satellite measurements as an indicator of vegetation phenology and productivity, we monitored spatial and temporal patterns of vegetation growth for a coastal wet sedge tundra site near Barrow, Alaska over three growing seasons (2000-2002). Contrary to expectation, earlier snowmelt did not lead to increased productivity. Instead, productivity was associated primarily with precipitation and soil moisture, and secondarily with growing degree days, which, during this period, led to reduced growth in years with earlier snowmelt. Additional moisture effects on productivity and species distribution, operating over a longer time scale, were evident in spatial NDVI patterns associated with microtopography. Lower, wetter regions dominated by graminoids were more productive than higher, drier locations having a higher percentage of lichens and mosses, despite the earlier snowmelt at the more elevated sites. These results call into question the oft-stated hypothesis that earlier arctic growing seasons will lead to greater vegetation productivity. Rather, they agree with an emerging body of evidence from recent field studies indicating that early-season, local environmental conditions, notably moisture and temperature, are primary factors determining arctic vegetation productivity. For this coastal arctic site, early growing season conditions are strongly influenced by microtopography, hydrology, and regional sea ice dynamics, and may not be easily predicted from snowmelt date or seasonal average air temperatures alone. Our comparison of field to satellite NDVI also highlights the value of in-situ monitoring of actual vegetation responses using field optical sampling to obtain detailed information on surface conditions not possible from satellite observations alone.

    Case managers mobilize family networks to care for patients. Family medical leave can be a resource for case managers who seek to enhance resilience among family caregivers. The Family Medical Leave Act, passed in 1993, was the first U.S. policy to regulate employee leaves from work for family care purposes (29 CFR 825.102). This policy offers family caregivers increased flexibility and equality. Current and emerging policies also can reduce financial strain. The discussion examines how case managers can integrate family medical leave into best-practice models to support patients and family caregivers.

  17. Parental leave and child health.

    Ruhm, C J

    2000-11-01

    This study investigates whether rights to parental leave improve pediatric health. Aggregate data are used for 16 European countries over the 1969 through 1994 period. More generous paid leave is found to reduce deaths of infants and young children. The magnitudes of the estimated effects are substantial, especially where a causal effect of leave is most plausible. In particular, there is a much stronger negative relationship between leave durations and post-neonatal or child fatalities than for perinatal mortality, neonatal deaths, or low birth weight. The evidence further suggests that parental leave may be a cost-effective method of bettering child health.

    This paper provides quasi-experimental evidence on the impact of paid leave legislation on fathers' leave-taking, as well as on the division of leave between mothers and fathers in dual-earner households. Using difference-in-difference and difference-in-difference-in-difference designs, we study California's Paid Family Leave (CA-PFL) program, which is the first source of government-provided paid parental leave available to fathers in the United States.

    Using difference-in-difference and difference-in-difference-in-difference designs, we study California's Paid Family Leave (CA-PFL) program, the first source of government-provided paid parental leave available to fathers in the Unites States. Relative to the pre-treatment mean, fathers of infants in California are 46 percent more likely to be on leave when CA-PFL is available. In households where both parents work, we find suggestive evidence that CA-PFL increases both father-only leave-taking (i.e., father on leave while mother is at work) and joint leave-taking (i.e., both parents on leave at the same time). Effects are larger for fathers of first-born children than for fathers of later-born children.

  4. Biological consequences of earlier snowmelt from desert dust deposition in alpine landscapes.

    Dust deposition to mountain snow cover, which has increased since the late 19(th) century, accelerates the rate of snowmelt by increasing the solar radiation absorbed by the snowpack. Snowmelt occurs earlier, but is decoupled from seasonal warming. Climate warming advances the timing of snowmelt and early season phenological events (e.g., the onset of greening and flowering); however, earlier snowmelt without warmer temperatures may have a different effect on phenology. Here, we report the results of a set of snowmelt manipulations in which radiation-absorbing fabric and the addition and removal of dust from the surface of the snowpack advanced or delayed snowmelt in the alpine tundra. These changes in the timing of snowmelt were superimposed on a system where the timing of snowmelt varies with topography and has been affected by increased dust loading. At the community level, phenology exhibited a threshold response to the timing of snowmelt. Greening and flowering were delayed before seasonal warming, after which there was a linear relationship between the date of snowmelt and the timing of phenological events. Consequently, the effects of earlier snowmelt on phenology differed in relation to topography, which resulted in increasing synchronicity in phenology across the alpine landscape with increasingly earlier snowmelt. The consequences of earlier snowmelt from increased dust deposition differ from climate warming and include delayed phenology, leading to synchronized growth and flowering across the landscape and the opportunity for altered species interactions, landscape-scale gene flow via pollination, and nutrient cycling.

  5. Carbohydrate production, balance and translocation in leaves, shoots and fruits of Montmorency sour cherry

    Kappes, E.M.

    1986-01-01

    Carbohydrate production, export and use were studied for different organs of sour cherry (Prunus cerasus L. Montmorency). Gross carbohydrate ( 14 CO 2 ) export started between 27.2 and 77.6% of full leaf expansion. The 10th leaf developing started export later than the 7th leaf, suggesting that higher carbohydrate availability during leaf expansion delays export initiation. In support of this, gross export started earlier (44.4-52.4% full expansion) after source leaf removal, than in the control (77.6%). Translocation was primarily vertical (following orthostichies). Most leaves of fruiting shoots exported bidirectionally to the apex and fruits, only leaves closest to fruits exported exclusively to fruits during rapid cell division (Stage I) and rapid cell expansion (Stage III). Net export, determined from carbohydrate balance models started at 17 and 51% expansion for the 7th and terminal leaf, and at 26.5% of shoot elongation. Cumulative carbohydrate production of the 7th and terminal leaves during the first 9 and 11 days after emergence, exceeded carbohydrate accumulated at final size, 464.2 and 148.9 mg. A fruit carbohydrate balance was developed to determine contributions by fruit photosynthesis and fruit respiration, and to identify periods of greatest carbohydrate import. Fruit photosynthesis during development was characterized under different environmental conditions. Gross photosynthesis and chlorophyll content per fruit increased to a maximum during stage II and decreased thereafter. Gross photosynthesis approached a maximum at 40 0 C. Since dark respiration increased exponentially over the same temperature range, net photosynthesis reached a maximum at 18 0 C. Photorespiration was not detected

    Under Austrian law, precautionary maternity leave is a decree issued by the district public health physician. It forbids a pregnant woman to work and mandates immediate maternity leave. Regular maternity leave for all women employed in all jobs begins at 32 weeks of gestation. Women who work in workplaces deemed dangerous and women with a history of obstetric problems such as premature or growth-retarded babies from previous pregnancies are regularly 'sent' into precautionary maternity leave. The public health physicians of Tirol's nine administrative districts were interviewed and supplied data on precautionary maternity leave from their districts. In 100 women who attended the clinic for pregnancies at risk of the Obstetrics/Gynecology Department of Innsbruck University Hospital and who had already obtained precautionary maternity leave, the medical/administrative procedure was studied in each case and correlated with pregnancy outcome. The town district of Innsbruck and the district that comprises the suburbs of the provincial capital had the highest rates of precautionary maternity leave. The town district of Innsbruck had a rate of 24.3% of all pregnant women (employed and not employed) in precautionary maternity leave in 1997, whereas the whole province of Tirol had 13.4%. More than 80% of decrees for precautionary maternity leave are issued by district public health physicians on the basis of written recommendations from gynecologists. One third of women who are sent into precautionary maternity leave are issued the decree prior to 12 weeks of gestation - mostly cases of multiple pregnancies and women with previous miscarriages. The present system of precautionary maternity leave appears to work in the sense that most working pregnant women with risk factors are correctly identified - with most errors on the side of caution. As the system also helps employers - the employee's pay is paid from the federal family support fund and state insurance once she is in

  7. Later endogenous circadian temperature nadir relative to an earlier wake time in older people

    The contribution of the circadian timing system to the age-related advance of sleep-wake timing was investigated in two experiments. In a constant routine protocol, we found that the average wake time and endogenous circadian phase of 44 older subjects were earlier than that of 101 young men. However, the earlier circadian phase of the older subjects actually occurred later relative to their habitual wake time than it did in young men. These results indicate that an age-related advance of circadian phase cannot fully account for the high prevalence of early morning awakening in healthy older people. In a second study, 13 older subjects and 10 young men were scheduled to a 28-h day, such that they were scheduled to sleep at many circadian phases. Self-reported awakening from scheduled sleep episodes and cognitive throughput during the second half of the wake episode varied markedly as a function of circadian phase in both groups. The rising phase of both rhythms was advanced in the older subjects, suggesting an age-related change in the circadian regulation of sleep-wake propensity. We hypothesize that under entrained conditions, these age-related changes in the relationship between circadian phase and wake time are likely associated with self-selected light exposure at an earlier circadian phase. This earlier exposure to light could account for the earlier clock hour to which the endogenous circadian pacemaker is entrained in older people and thereby further increase their propensity to awaken at an even earlier time.

    We describe the case of a 37-year-old woman who presented with complete right bundle branch block and right axis deviation. She was admitted to our hospital due to severe heart failure and was dependent on inotropic agents. Cardiac resynchronization therapy was initiated but did not improve her condition. After the optimization of the pacing timing, we performed earlier right ventricular pacing, which led to an improvement of her heart failure. Earlier right ventricular pacing should be considered in patients with complete right bundle branch block and right axis deviation when cardiac resynchronization therapy is not effective.

Under the provisions of the voluntary saved leave scheme (SLS), a maximum total of 10 days'2)Previously, every person taking part in the scheme has been individually issued with a form for the purposes of requesting the transfer of leave to the leave account and the transfer has then had to be done manually by HR Division. To streamline the procedure, unused leave of all those taking part in the saved leave scheme at the closure of the leave-year accounts will henceforth be transferred automatically to the saved leave account on that date. This simplification is in the interest of all parties concerned. This automatic transfer procedure has a number of advantages for participants in the SLS scheme. First, staff members will no longer have to take any administrative steps. Secondly, the new proced...

    Smoking is associated with early postoperative complications, increased length of hospital stay, and an increased risk of revision after total knee arthroplasty (TKA). However, the effect of smoking on time to revision TKA is unknown. A total of 619 primary TKAs referred to an academic tertiary center for revision TKA were retrospectively stratified according to the patient smoking status. Smoking status was then analyzed for associations with time to revision TKA using a Chi square test. The association was also analyzed according to the indication for revision TKA. Smokers (37/41, 90%) have an increased risk of earlier revision for any reason compared to non-smokers (274/357, 77%, p=0.031). Smokers (37/41, 90%) have an increased risk of earlier revision for any reason compared to ex-smokers (168/221, 76%, p=0.028). Subgroup analysis did not reveal a difference in indication for revision TKA (p>0.05). Smokers are at increased risk of earlier revision TKA when compared to non-smokers and ex-smokers. The risk for ex-smokers was similar to that of non-smokers. Smoking appears to have an all-or-none effect on earlier revision TKA as patients who smoked more did not have higher risk of early revision TKA. These results highlight the need for clinicians to urge patients not to begin smoking and encourage smokers to quit smoking prior to primary TKA. Copyright © 2017 Elsevier B.V. All rights reserved.

    Increasing attention has been focused on parental leave, but little is known about early leave and parental experiences for male and female attending physicians. Our goal was to describe and quantify the parental leave experiences of a nationally representative sample of emergency physicians (EP). We conducted a web-based survey, distributed via emergency medicine professional organizations, discussion boards, and listservs, to address study objectives. We analyzed data from 464 respondents; 56% were women. Most experienced childbirth while employed as an EP. Fifty-three percent of women and 60% of men reported working in a setting with a formal maternity leave policy; however, 36% of women and 18% of men reported dissatisfaction with these policies. Most reported that other group members cover maternity-related shift vacancies; a minority reported that pregnant partners work extra shifts prior to leave. Leave duration and compensation varied widely, ranging from no compensated leave (18%) to 12 or more weeks at 100% salary (7%). Supportive attitudes were reported during pregnancy (53%) and, to a lesser degree (43%), during leave. Policy improvement suggestions included the development of clear, formal policies; improving leave duration and compensation; adding paternity and adoption leave; providing support for physicians working extra to cover colleagues' leave; and addressing breastfeeding issues. In this national sample of EPs, maternity leave policies varied widely. The duration and compensation during leave also had significant variation. Participants suggested formalizing policies, increasing leave duration and compensation, adding paternity leave, and changing the coverage for vacancies to relieve burden on physician colleagues.

    To assess if observed higher observed risks of cardiac complications for patients with Kawasaki disease (KD) treated earlier may reflect bias due to confounding from initial disease severity, as opposed to any negative effect of earlier treatment. We used data from Japanese nationwide KD surveys from 1997 to 2004. Receipt of additional intravenous immunoglobulin (IVIG) (data available all years) or any additional treatment (available for 2003-2004) were assessed as proxies for initial disease severity. We determined associations between earlier or later IVIG treatment (defined as receipt of IVIG on days 1-4 vs days 5-10 of illness) and cardiac complications by stratifying by receipt of additional treatment or by using logistic modeling to control for the effect of receiving additional treatment. A total of 48 310 patients with KD were included in the analysis. In unadjusted analysis, earlier IVIG treatment was associated with a higher risk for 4 categories of cardiac complications, including all major cardiac complications (risk ratio, 1.10; 95% CI, 1.06-1.15). Stratifying by receipt of additional treatment removed this association, and earlier IVIG treatment became protective against all major cardiac complications when controlling for any additional treatment in logistic regressions (OR, 0.90; 95% CI, 0.80-1.00). Observed higher risks of cardiac complications among patients with KD receiving IVIG treatment on days 1-4 of the illness are most likely due to underlying higher initial disease severity, and patients with KD should continue to be treated with IVIG as early as possible.

    Although earlier trauma exposure is known to predict posttraumatic stress disorder (PTSD) after subsequent traumas, it is unclear whether this association is limited to cases where the earlier trauma led to PTSD. Resolution of this uncertainty has important implications for research on pretrauma vulnerability to PTSD. We examined this issue in the World Health Organization (WHO) World Mental Health (WMH) Surveys with 34 676 respondents who reported lifetime trauma exposure. One lifetime trauma was selected randomly for each respondent. DSM-IV (Diagnostic and Statistical Manual of Mental Disorders, 4th Edition) PTSD due to that trauma was assessed. We reported in a previous paper that four earlier traumas involving interpersonal violence significantly predicted PTSD after subsequent random traumas (odds ratio (OR)=1.3-2.5). We also assessed 14 lifetime DSM-IV mood, anxiety, disruptive behavior and substance disorders before random traumas. We show in the current report that only prior anxiety disorders significantly predicted PTSD in a multivariate model (OR=1.5-4.3) and that these disorders interacted significantly with three of the earlier traumas (witnessing atrocities, physical violence victimization and rape). History of witnessing atrocities significantly predicted PTSD after subsequent random traumas only among respondents with prior PTSD (OR=5.6). Histories of physical violence victimization (OR=1.5) and rape after age 17 years (OR=17.6) significantly predicted only among respondents with no history of prior anxiety disorders. Although only preliminary due to reliance on retrospective reports, these results suggest that history of anxiety disorders and history of a limited number of earlier traumas might usefully be targeted in future prospective studies as distinct foci of research on individual differences in vulnerability to PTSD after subsequent traumas.Molecular Psychiatry advance online publication, 19 September 2017; doi:10.1038/mp.2017.194.

    This longitudinal study examined the association between psychosocial antecedents, including illicit drug use, and adult compulsive buying (CB) across a 29-year time period from mean age 14 to mean age 43. Participants originally came from a community-based random sample of residents in two upstate New York counties. Multivariate linear regression analysis was used to study the relationship between the participant’s earlier psychosocial antecedents and adult CB in the fifth decade of life. The results of the multivariate linear regression analyses showed that gender (female), earlier adult impulse buying (IB), depressive mood, illicit drug use, and concurrent ADHD symptoms were all significantly associated with adult CB at mean age 43. It is important that clinicians treating CB in adults should consider the role of drug use, symptoms of ADHD, IB, depression, and family factors in CB. PMID:26165963

    2001-01-01

    The objective of this paper is to provide practical assistance on judging the safety of a nuclear power plant, on the basis of a comparison with current safety standards and operational practices. For nuclear power plants built to earlier standards for which there are questions about the adequacy of the maintenance of the plant design and operational practices, a safety review against current standards and practices can be considered a high priority. The objective of reviewing nuclear power plants built to earlier standards against current standards and practices is to determine whether there are any deviations which would have an impact on plant safety. The safety significance of the issues identified should be judged according to their implications for plant design and operation in terms of basic safety concepts such as defence in depth and safety culture. In addition, this paper provides assistance on the prioritization of corrective measures and their implementation so as to approach an acceptable level of safety

  8. A vantage from space can detect earlier drought onset: an approach using relative humidity.

    Farahmand, Alireza; AghaKouchak, Amir; Teixeira, Joao

    2015-02-25

    Each year, droughts cause significant economic and agricultural losses across the world. The early warning and onset detection of drought is of particular importance for effective agriculture and water resource management. Previous studies show that the Standard Precipitation Index (SPI), a measure of precipitation deficit, detects drought onset earlier than other indicators. Here we show that satellite-based near surface air relative humidity data can further improve drought onset detection and early warning. This paper introduces the Standardized Relative Humidity Index (SRHI) based on the NASA Atmospheric Infrared Sounder (AIRS) observations. The results indicate that the SRHI typically detects the drought onset earlier than the SPI. While the AIRS mission was not originally designed for drought monitoring, we show that its relative humidity data offers a new and unique avenue for drought monitoring and early warning. We conclude that the early warning aspects of SRHI may have merit for integration into current drought monitoring systems.

    Speech perception is heavily influenced by surrounding sounds. When spectral properties differ between earlier (context) and later (target) sounds, this can produce spectral contrast effects (SCEs) that bias perception of later sounds. For example, when context sounds have more energy in low-F 1 frequency regions, listeners report more high-F 1 responses to a target vowel, and vice versa. SCEs have been reported using various approaches for a wide range of stimuli, but most often, large spectral peaks were added to the context to bias speech categorization. This obscures the lower limit of perceptual sensitivity to spectral properties of earlier sounds, i.e., when SCEs begin to bias speech categorization. Listeners categorized vowels (/ɪ/-/ɛ/, Experiment 1) or consonants (/d/-/g/, Experiment 2) following a context sentence with little spectral amplification (+1 to +4 dB) in frequency regions known to produce SCEs. In both experiments, +3 and +4 dB amplification in key frequency regions of the context produced SCEs, but lesser amplification was insufficient to bias performance. This establishes a lower limit of perceptual sensitivity where spectral differences across sounds can bias subsequent speech categorization. These results are consistent with proposed adaptation-based mechanisms that potentially underlie SCEs in auditory perception. Recent sounds can change what speech sounds we hear later. This can occur when the average frequency composition of earlier sounds differs from that of later sounds, biasing how they are perceived. These "spectral contrast effects" are widely observed when sounds' frequency compositions differ substantially. We reveal the lower limit of these effects, as +3 dB amplification of key frequency regions in earlier sounds was enough to bias categorization of the following vowel or consonant sound. Speech categorization being biased by very small spectral differences across sounds suggests that spectral contrast effects occur

    Discussion: The regions that demonstrated significant positive linear relationships between the number of adolescent years using substances and connectivity with NAcc are nodes in the right frontoparietal network, which is central to cognitive control. The coupling of reward and cognitive control networks may be a mechanism through which earlier onset of substance use is related to brain function over time, a trajectory that may be implicated in subsequent substance use disorders.

    Women physicians must consider many conflicting issues when timing childbirth. We characterized maternity leave, breast-feeding practices and satisfaction associated with pregnancy timing in women urologists. A 114-item anonymous survey including questions on maternity leave duration for firstborn children, workplace policies, attitudes and satisfaction was mailed to all 365 American board certified women urologists in May and July 2007. Logistic regression was used to identify factors associated with greater satisfaction. A total of 243 women urologists (69%) responded, of whom 158 had at least 1 biological child. Average maternal age at first birth was 32.6 years. Of the children 10%, 32% and 52% were born before, during and after residency, respectively. Only 42% of women reported the existence of a formal maternity leave policy. Of the women 70% took 8 weeks or less of leave. Those with 9 weeks or greater were 3.8 times more likely to report satisfaction (p = 0.001). Although women in practice were 2.0 times more likely to take 9 weeks or greater compared to those in training or earlier (p = 0.046), only 30% in practice took this much time. Dissatisfaction with leave was not related to birth timing (residency vs practice) or maternal age at delivery but to work/residency related issues in 69% of respondents, financial concerns in 13% and personal/other in 18%. For breast-feeding 67% of respondents were satisfied with the duration and 22% were not. Dissatisfaction was secondary to work factors. Satisfaction with leave was related to the amount of maternity leave with women with 9 weeks or greater more likely to report satisfaction. Women in practice were more likely to take 9 weeks or greater but most did not due to strong stressors related to work, partners/peers or finances. Work factors were cited for dissatisfaction with breast-feeding.

    This study investigates the relationship between organizational citizenship behavior (OCB) and employee intention to leave the organization and current job using a sample of French employees. A survey was sent to 1,200 alumni of a business school in France. Participation in the study was voluntary. The participants were 355 working adults with French citizenship. This paper provides several interesting findings. While no relationship was found between altruism and intention to leave both the organization and the current job, sportsmanship, civic virtue and helping others emerged as the strongest predictors of intention to leave the organization and intention to leave the current job. Results are discussed.

    The United States is the only major industrialized country in the world to not require paid parental leave. Numerous studies have shown that allowing parents time with a newborn makes the child and the parents healthier, both physically and mentally. Many physicians, especially those who work in practices with five or fewer doctors, worry about how to pay for parental leave for themselves and their staff.

    In Spanish, the concepts of discapacidad (disability leave) and incapacidad (sick leave) jointly refer to the impairment of a person due to injuries, diseases or deficiencies that limit their activity in a social, personal or occupational field. However, this common link does not imply that both concepts are the same. Statistical data from INE (Instituto Nacional de Estadística: Statistic National Institute) show that Spain had in 2015 3.85 million persons with a disability (59.8% were women). Statistical data from 2015 from INSS (Instituto Nacional de Seguridad Social: Social Security National Institute) show high levels in the number of processes and in workers affected by temporary sick leave, with social costs to the social security system. Both concepts have been updated: about disability leave, Law 39/2006 adjusted terminology by avoiding the use of concepts with discriminating or pejorative connotation. Regarding sick leave, the Ley General de Seguridad Social (General Social Security Law)has been amended and came into effect in January, 2016. It is necessary to know and distinguish these aspects for a better administrative management, and a more oriented information to the affected patient.

    The association between Down syndrome and pulmonary hypertension could contribute to more severe pulmonary regurgitation after tetralogy of Fallot repair and possibly earlier pulmonary valve replacement. We compared cardiac magnetic resonance measures of pulmonary regurgitation and right ventricular dilation as well as timing of pulmonary valve replacement between those with and without Down syndrome after tetralogy of Fallot repair. Review of our surgical database from 2000 to 2015 identified patients with tetralogy of Fallot with pulmonary stenosis. Those with Down syndrome were compared to those without. The primary outcome of interest was time from repair to pulmonary valve replacement. Secondary outcomes included pulmonary regurgitation and indexed right ventricular volume on cardiac magnetic resonance imaging. The cohort of 284 patients included 35 (12%) with Down syndrome. Transannular patch repair was performed in 210 (74%). Down syndrome showed greater degree of pulmonary regurgitation (55 ± 14 vs. 37 ± 16%, p = 0.01) without a significantly greater rate of right ventricular dilation (p = 0.09). In multivariable analysis, Down syndrome (HR 2.3, 95% CI 1.2-4.5, p = 0.02) and transannular patch repair (HR 5.5, 95% CI 1.7-17.6, p = 0.004) were significant risk factors for valve replacement. Those with Down syndrome had significantly lower freedom from valve replacement (p = 0.03). Down syndrome is associated with an increased degree of pulmonary regurgitation and earlier pulmonary valve replacement after tetralogy of Fallot repair. These patients require earlier assessment by cardiac magnetic resonance imaging to determine timing of pulmonary valve replacement and evaluation for and treatment of preventable causes of pulmonary hypertension.

    To determine whether earlier time to initiation of aerobic exercise following acute concussion is associated with time to full return to (1) sport and (2) school or work. A retrospective stratified propensity score survival analysis of acute (≤14 days) concussion was used to determine whether time (days) to initiation of aerobic exercise post-concussion was associated with, both, time (days) to full return to (1) sport and (2) school or work. A total of 253 acute concussions [median (IQR) age, 17.0 (15.0-20.0) years; 148 (58.5%) males] were included in this study. Multivariate Cox regression models identified that earlier time to aerobic exercise was associated with faster return to sport and school/work adjusting for other covariates, including quintile propensity strata. For each successive day in delay to initiation of aerobic exercise, individuals had a less favourable recovery trajectory. Initiating aerobic exercise at 3 and 7 days following injury was associated with a respective 36.5% (HR, 0.63; 95% CI, 0.53-0.76) and 73.2% (HR, 0.27; 95% CI, 0.16-0.45) reduced probability of faster full return to sport compared to within 1 day; and a respective 45.9% (HR, 0.54; 95% CI, 0.44-0.66) and 83.1% (HR, 0.17; 95% CI, 0.10-0.30) reduced probability of faster full return to school/work. Additionally, concussion history, symptom severity, LOC deleteriously influenced concussion recovery. Earlier initiation of aerobic exercise was associated with faster full return to sport and school or work. This study provides greater insight into the benefits and safety of aerobic exercise within the first week of the injury.

    Impaired insight into illness in schizophrenia is associated with illness severity and deficits in premorbid intellectual function, executive function, and memory. A previous study of patients aged 60 years and older found that illness severity and premorbid intellectual function accounted for variance in insight impairment. As such, we aimed to test whether similar relationships would be observed in earlier life. A retrospective analysis was performed on 1 large sample of participants (n = 171) with a DSM-IV-TR diagnosis of schizophrenia aged 19 to 79 years acquired from 2 studies: (1) a psychosocial intervention trial for older persons with schizophrenia (June 2008 to May 2014) and (2) a diffusion tensor imaging and genetics study of psychosis across the life span (February 2007 to December 2013). We assessed insight into illness using the Positive and Negative Syndrome Scale (PANSS) item G12 and explored its relationship to illness severity (PANSS total modified), premorbid intellectual function (Wechsler Test of Adult Reading [WTAR]), and cognition. Insight impairment was more severe in later life (≥ 60 years) than in earlier years (t = -3.75, P insight was explained by PANSS total modified (Exp[B] = 1.070, P insight, they did not independently contribute to its variance. However, the relationships between impaired insight and illness severity and between impaired insight and cognition, particularly working memory, were stronger in later life than in earlier life. These results suggest an opportunity for intervention may exist with cognitive-enhancing neurostimulation or medications to improve insight into illness in schizophrenia across the life span.

    Warming temperatures cause temporal changes in growing seasons and prey abundance that drive earlier breeding by birds, especially dietary specialists within homogeneous habitat. Less is known about how generalists respond to climate-associated shifts in growing seasons or prey phenology, which may occur at different rates across land cover types. We studied whether breeding phenology of a generalist predator, the American kestrel (Falco sparverius), was associated with shifts in growing seasons and, presumably, prey abundance, in a mosaic of non-irrigated shrub/grasslands and irrigated crops/pastures. We examined the relationship between remotely-sensed normalized difference vegetation index (NDVI) and abundance of small mammals that, with insects, constitute approximately 93% of kestrel diet biomass. We used NDVI to estimate the start of the growing season (SoGS) in irrigated and non-irrigated lands from 1992 to 2015 and tested whether either estimate of annual SoGS predicted the timing of kestrel nesting. Finally, we examined relationships among irrigated SoGS, weather and crop planting. NDVI was a useful proxy for kestrel prey because it predicted small mammal abundance and past studies showed that NDVI predicts insect abundance. NDVI-estimated SoGS advanced significantly in irrigated lands (β = -1·09 ± 0·30 SE) but not in non-irrigated lands (β = -0·57 ± 0·53). Average date of kestrel nesting advanced 15 days in the past 24 years and was positively associated with the SoGS in irrigated lands, but not the SoGS in non-irrigated lands. Advanced SoGS in irrigated lands was related to earlier planting of crops after relatively warm winters, which were more common in recent years. Despite different patterns of SoGS change between land cover types, kestrel nesting phenology shifted with earlier prey availability in irrigated lands. Kestrels may preferentially track prey in irrigated lands over non-irrigated lands because of higher quality prey on

    Returning to work after maternity leave can be a challenging, anxious and fraught experience for women, and has been portrayed in the literature as a generally negative experience. Interestingly, although occupational therapists were predominantly women, no research was found focussing on their experiences of returning to work after maternity leave. The aim of this research was to gain an insight into occupational therapists' experiences of returning to work following maternity leave. Principles of interpretive phenomenological analysis were used to explore the individual experiences of six Australian occupational therapists returning to work after a period of maternity leave. Individual semi-structured interviews lasting up to 90 minutes were conducted. Interviews were audio-recorded, transcribed and then analysed. Two major themes emerged from the analysis of interviews: compromise and feeling valued. The experience of returning to work was a process of compromise in which women found strategies to cope with their changing roles and demands, to find a balance between home and work life. The women wanted to feel valued by their managers and co-workers, as this enabled them to feel comfortable and confident with some of the compromises they made. Occupational therapists returning to work after maternity leave will make compromises so that they can balance their home and work life. Occupational therapists value managers and co-workers who understand the compromises women make when returning to work following maternity leave and who create a supportive workplace that acknowledges and values their contribution. © 2013 Occupational Therapy Australia.

    This study investigated the effects of skin-to-skin contact on breastfeeding attainment, duration and infant growth in preterm infants, as this has not been sufficiently explored. A prospective longitudinal study on Kangaroo mother care was carried out, comprising 104 infants with a gestational age of 28 + 0 to 33 + 6 and followed up to one year of corrected age. Parents and staff recorded the duration of skin-to skin contact during the stay in the neonatal intensive care unit (NICU). Medical data were collected through patient records, and follow-up questionnaires were filled in by parents. The 53 infants who attained full breastfeeding in the NICU did so at a median (range) of 35 + 0 (32 + 1 to 37 + 5) weeks of postmenstrual age, and skin-to-skin contact was the only factor that influenced earlier attainment in the regression analysis (R(2) 0.215 p skin-to-skin contact during the stay in the NICU did not affect the duration of breastfeeding or infant growth after discharge. Furthermore, infant growth was not affected by the feeding strategy of exclusive, partial breastfeeding or no breastfeeding. A longer daily duration of skin-to-skin contact in the NICU was associated with earlier attainment of exclusive breastfeeding. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    Objective: To investigate the difference between the early phases and delay phase of three-phase bone scintigraphy on hemiplegic patients with earlier complex regional pain syndrome (CRPS). Methods: Twenty-nine stroke patients with hemiplegia complicating CRPS received three-phase bone scintigraphy after intravenous injection of 99 Tc m -methylene diphosphonate (MDP). The region of interest (ROI) technique was used to obtain the radioactive counts of involved joints and contralateral sites on wrists, metacarpophalangeal, proximal interphalangeal and distal interphalangeal joints. The total counts of these four sites in each patient were then obtained and the total uptake ratios of involved joints/contralateral joints for each phase were calculated to compare the difference among the three phases. Wilcoxon test and ANOVA were used in data analyses. Results: The involved joints of hemiplegic side displayed higher tracer uptake. There were significant differences of the radioactive counts between involved joints and uninvolved ones in the perfusion, pool and delay phase (Wilcoxon test, Z: -4.73 to -2.10, P<0.05). There was no significant difference of total uptake ratios of involved joints/contralateral joints among the three phases (ANOVA, F = 0. 807, P < 0.05). Conclusions: Due to higher bone seeking agent accumulation on three-phase bone scintigraphy, both early phases and delay phase imaging showed similar value in stroke patients with hemiplegia complicating earlier CRPS.

    Early adolescent onset of substance use is a robust predictor of future substance use disorders. We examined the relation between age of substance use initiation and resting state functional connectivity (RSFC) of the core reward processing (nucleus accumbens; NAcc) to cognitive control (prefrontal cortex; PFC) brain networks. Adolescents in a longitudinal study of Mexican-origin youth reported their substance use annually from ages 10 to 16 years. At age 16, 69 adolescents participated in a resting state functional magnetic resonance imaging scan. Seed-based correlational analyses were conducted using regions of interest in bilateral NAcc. The earlier that adolescents initiated substance use, the stronger the connectivity between bilateral NAcc and right dorsolateral PFC, right dorsomedial PFC, right pre-supplementary motor area, right inferior parietal lobule, and left medial temporal gyrus. The regions that demonstrated significant positive linear relationships between the number of adolescent years using substances and connectivity with NAcc are nodes in the right frontoparietal network, which is central to cognitive control. The coupling of reward and cognitive control networks may be a mechanism through which earlier onset of substance use is related to brain function over time, a trajectory that may be implicated in subsequent substance use disorders.

    The ecological impact of night-time lighting is of concern because of its well-demonstrated effects on animal behaviour. However, the potential of light pollution to change plant phenology and its corresponding knock-on effects on associated herbivores are less clear. Here, we test if artificial lighting can advance the timing of budburst in trees. We took a UK-wide 13 year dataset of spatially referenced budburst data from four deciduous tree species and matched it with both satellite imagery of night-time lighting and average spring temperature. We find that budburst occurs up to 7.5 days earlier in brighter areas, with the relationship being more pronounced for later-budding species. Excluding large urban areas from the analysis showed an even more pronounced advance of budburst, confirming that the urban 'heat-island' effect is not the sole cause of earlier urban budburst. Similarly, the advance in budburst across all sites is too large to be explained by increases in temperature alone. This dramatic advance of budburst illustrates the need for further experimental investigation into the impact of artificial night-time lighting on plant phenology and subsequent species interactions. As light pollution is a growing global phenomenon, the findings of this study are likely to be applicable to a wide range of species interactions across the world. © 2016 The Authors.

    Full Text Available This article aims to show the results of the review of literature of relevant studies of the causal elements of intention to leave in the last five years (2009-2013. The method used to evaluate the literature was based on the seven steps for research synthesis: problem formulation, literature search, obtaining information from studies, quality assessment studies, analysis and integration of results, interpretation of evidence and presentation of results. 48 studies from 15 different countries with a sample of 35804 employees of different companies were evaluated. The findings suggest the existence of 89 different variables influencing the intention to leave of employees in an organization. The results of this study will allow researchers to better understand the variables that can be studied to verify the impact of variables such as causal elements, but also see those that have a mediating effect between them for predicting intention to leave as an element of employee turnover. This study makes three important contributions to literature of turnover. First, in this study all the parameters associated with the intention to leave were checked. Second, this study categorizes and displays in proportion relevant interests to the scientific community whom studying employee turnover across the intention to leave. And thirdly provides clues organizations to improve some of its structural and contextual features to control turnover.

    We use data from the Survey of Income and Program Participation to examine the impact of leave entitlements on unpaid leave usage by men and women after the birth of a child from 1991 to 1999. The results indicate that legislation providing the right to unpaid leave has not affected men's leave usage. The results for women are mixed: in some specifications, leave entitlements are associated with increased leave taking or longer leaves, but the results depend on how we define leave coverage. Our results point to the limited impact of unpaid leave policies and the potential importance of paid-leave policies.

The main aim of the program was to increase the chances of the unemployed finding a job. However, the empirical analysis reveals a clear negative...... relationship between the unemployment rate and transition rates from employment into the paid leave scheme. Program participation is low, precisely in those labor market states, where the scheme has a potential to perform as a remedy by increasing the transition rate from unemployment to employment.

    Rigor mortis is thought to be related to falling ATP levels in muscles postmortem. We measured rigor mortis as tension determined isometrically in three rat leg muscles in liquid paraffin kept at 37 degrees C or 25 degrees C--two red muscles, red gastrocnemius (RG) and soleus (SO) and one white muscle, white gastrocnemius (WG). Onset, half and full rigor mortis occurred earlier in RG and SO than in WG both at 37 degrees C and at 25 degrees C even though RG and WG were portions of the same muscle. This suggests that rigor mortis directly reflects the postmortem intramuscular ATP level, which decreases more rapidly in red muscle than in white muscle after death. Rigor mortis was more retarded at 25 degrees C than at 37 degrees C in each type of muscle.

    Full Text Available BIRDEM is the largest referral center of diabetes in the world. It registered more than 300,000 diabetic patients from 1956 to 2005. This retrospective study compared the biophysical characteristics of diabetic patients registered in 1995 to those registered in 2005. Information on social (income, education, clinical (height, weight, blood pressure and oral glucose tolerance (OGTT of patients registered in 1995 and 2005 were retrieved from the BIRDEM registry. The age group ³ 20y was considered eligible. Overall, there were 11489 patients for 1995 and 19580 for 2005. Compared with the registry of 1995, a significant increase of registry for female patients were observed (39.5 vs. 46.7%, p<0.001 and also the rural population (31.9 vs. 47.4%, p<0.001. Likewise, the number of poor social class was also found higher in 2005 (5.2 vs. 25.5%, p<0.001. Young aged (<40y registry was also significantly higher in 2005 (34.4 vs. 37.1%, p<0.001. Compared with the registered patients of 1995, adjusted for sex and area, those of 2005 had a significantly higher BMI, higher FPG and higher 2hPG (for all, p<0.001. In contrast, a significantly lower age, lower height and lower blood pressure were observed in those of 2005. We conclude that the age at registration for diabetes has decreased significantly in 2005 compared to that in 1995 indicating an earlier onset of diabetes. Significantly higher obesity in the year 2005 than 1995 indicates that there has been an increase in obesity that might be an important contributing factor for earlier onset of diabetes. Ibrahim Med.

    Design for Manufacturing (DFM), especially the use of manufacturing knowledge to support design decisions, has received attention in the academic domain. However, industry practice has not been studied enough to provide solutions that are mature for industry. The current state of the art for DFM is often rule-based functionality within Computer-Aided Design (CAD) systems that enforce specific design requirements. That rule-based functionality may or may not dynamically affect geometry definition. And, if rule-based functionality exists in the CAD system, it is typically a customization on a case-by-case basis. Manufacturing knowledge is a phrase with vast meanings, which may include knowledge on the effects of material properties decisions, machine and process capabilities, or understanding the unintended consequences of design decisions on manufacturing. One of the DFM questions to answer is how can manufacturing knowledge, depending on its definition, be used earlier in the product lifecycle to enable a more collaborative development environment? This paper will discuss the results of a workshop on manufacturing knowledge that highlights several research questions needing more study. This paper proposes recommendations for investigating the relationship of manufacturing knowledge with shape, behavior, and context characteristics of product to produce a better understanding of what knowledge is most important. In addition, the proposal includes recommendations for investigating the system-level barriers to reusing manufacturing knowledge and how model-based manufacturing may ease the burden of knowledge sharing. Lastly, the proposal addresses the direction of future research for holistic solutions of using manufacturing knowledge earlier in the product lifecycle.

    To evaluate the clinical presentation of retinoblastoma in Alexandria, Egypt, correlate the timing of accurate diagnosis with the presence of advanced disease and identify causes of delayed presentation. Retrospective noncomparative single institution study reviews demographic and clinical data of all new children with retinoblastoma presenting to Alexandria Main University ocular oncology clinic (OOC) from January 2012 to June 2014. Diagnosis time was from initial parental complaint to retinoblastoma diagnosis and referral time was from retinoblastoma diagnosis to presentation to the Alexandria OCC. Delayed Diagnosis and referral were counted if >2 weeks. Advanced presentation is defined as clinical TNMH (8th edition) staging of cT2 or cT3 (international intraocular retinoblastoma classification group D or E) in at least one eye or the presence of extra-ocular disease (cT4). Seventy eyes of 47 children were eligible: 52% unilateral, 7% with family history and 96% presented with leukocorea. Sixty-four percent of children had advanced intraocular disease and none had extra-ocular disease. Delayed presentation occurred in 58% of children and was significantly associated with advanced disease in both unilaterally and bilaterally affected children (p = 0.003, 0.002 respectively). The delay in diagnosis was more in unilateral cases while the delay in referral was more in bilateral cases. The main cause of delayed presentation in unilateral retinoblastoma was misdiagnosis (30%) while parental shopping for second medical opinion (30%) was the main cause in bilateral children. Delayed diagnosis is a problem affecting retinoblastoma management. Better medical education and training, health education and earlier screening are recommended to achieve earlier diagnosis.

    It has been hypothesized that BRCA1/2 mutation carriers have an earlier age at natural menopause (ANM), although to date findings are inconclusive. This study assessed the influence of BRCA mutation status on ANM, and aimed to explore the reasons of inconsistency in the literature. Cross-sectional assessment from an ongoing nationwide cohort study among members of BRCA1/2 mutated families. Information was obtained by a standardized questionnaire. Kaplan-Meier curves were constructed, and Cox regression was used to assess the association between BRCA1/2 mutation status and ANM. Adjustments were made for birth cohort, family, smoking, use of hormonal contraceptives, and parity. A total of 1,208 BRCA1/2 mutation carriers and 2,211 proven noncarriers were included. Overall, no association was found between BRCA1/2 mutation status and ANM (adjusted hazard ratio [HR] = 1.06 [95% CI, 0.87-1.30]). We examined if the null finding was due to informative censoring by uptake of risk-reducing salpingo-oophorectomy. Indeed, within the oldest birth cohort, in which the percentage of surgical menopause events was lowest and comparable between carriers and noncarriers, the HR for earlier natural menopause in carriers was 1.45 (95% CI, 1.09-1.94). The second oldest birth cohort, however, demonstrated a decreased HR (0.67 [95% CI, 0.46-0.98]), and thus no trend over birth cohorts was found. Various types of selection bias hamper the comparison of ANM between BRCA1/2 mutation carriers and noncarriers, genetically tested in the clinic.

  4. Watch out for the leaves!

    2013-01-01

    Now that autumn is here, dead leaves falling from the trees form a colourful carpet that is pleasing to the eye. However, the reality is less pleasant for pedestrians, since these leaves increase the risk of slipping and falling, especially when the ground is wet.   These conditions are also hazardous for two- and four-wheeled vehicles, whose grip on the ground can be severely reduced, thereby increasing the risk of them skidding out of control. Cyclists are among the most vulnerable road users when faced with these hazards. It is therefore essential to be alert to the dangers, which can be lessened by taking a few simple precautions such as moderating your speed and wearing suitable shoes. We also invite you to notify the Service Desk if you notice a road or pavement where there is a high concentration of dead leaves. The CERN Roads and Drainage Service will then ensure that the leaves are cleared in order to reduce the risk of accidents in the area.

    For nurses, moral distress leads to burnout, attrition, compassion fatigue, and patient avoidance. Using a quantitative, cross-sectional, and descriptive design, we assessed the frequency, intensity, and type of moral distress in 51 emergency nurses in 1 community hospital using a 21-item, self-report, Likert-type questionnaire. Results showed a total mean moral distress level of 3.18, indicative of overall low moral distress. Situations with the highest levels of moral distress were related to the competency of health care providers and following family wishes to continue life support, also known as futile care. Moral distress was the reason given by 6.6% of registered nurses for leaving a previous position, 20% said that they had considered leaving a position but did not, and 13.3% stated that they are currently considering leaving their position because of moral distress.

    To examine the nutrition-related factors associated with motor and language development among young children living in a poor urban area of Haiti. Children aged 6-11 months (n = 583) were enrolled and followed monthly for one year. World Health Organization motor developmental milestones and vowel and consonant counts were assessed. Longitudinal regression models were applied to assess the association of anthropometric, dietary intake, infectious disease morbidity and socio-economic and demographic factors on developmental outcomes. At baseline, 9.4% were stunted or length-for-age Z score < -2, and 30.2% were mild-to-moderately stunted or length-for-age Z score < -1. Stunting status was significantly associated with motor and phonetic language acquisition at each time point during infancy. Several nutrition factors significantly predicted earlier achievement of motor and language development outcomes in longitudinal models: child anthropometry; breastfeeding and complementary feeding frequencies; dietary diversity; egg and oil intake; and reduced infectious disease morbidities. Increases in the length-for-age Z score significantly predicted all motor and language outcomes and yielded the best fit models compared to other anthropometric indicators (p < 0.001). Child development interventions may be enhanced by incorporating nutrition strategies such as improved diet quality, breastfeeding promotion and diarrhoeal disease mitigation. ©2016 Foundation Acta Paediatrica.

    DYT1 early-onset generalized torsion dystonia is an inherited movement disorder caused by mutations in DYT1 coding for torsinA with ∼30% penetrance. Most of the DYT1 dystonia patients exhibit symptoms during childhood and adolescence. On the other hand, DYT1 mutation carriers without symptoms during these periods mostly do not exhibit symptoms later in their life. Little is known about what controls the timing of the onset, a critical issue for DYT1 mutation carriers. DYT11 myoclonus-dystonia is caused by mutations in SGCE coding for ε-sarcoglycan. Two dystonia patients from a single family with double mutations in DYT1 and SGCE exhibited more severe symptoms. A recent study suggested that torsinA contributes to the quality control of ε-sarcoglycan. Here, we derived mice carrying mutations in both Dyt1 and Sgce and found that these double mutant mice showed earlier onset of motor deficits in beam-walking test. A novel monoclonal antibody against mouse ε-sarcoglycan was developed by using Sgce knock-out mice to avoid the immune tolerance. Western blot analysis suggested that functional deficits of torsinA and ε-sarcoglycan may independently cause motor deficits. Examining additional mutations in other dystonia genes may be beneficial to predict the onset in DYT1 mutation carriers.

    The problems of safety of WWER-440/V-230 type reactors are discussed, and the following conclusions are made. (1) The reactors have a very good operational record. (2) The reactors have serious design shortcomings, which should be eliminated by safety upgrading. Core damage frequency should be further reduced. (3) PSA methods constitute an appropriate tool for assessment of plant vulnerability to some initiating events and malfunctions, for prioritization of upgrading measures and for tolerability of deviations from current safety standards. (4) The most important safety merits, such as a large thermal inertia and low rupture probability, should be properly taken into account in the analysis. (5) Extensive safety upgrading is feasible and can lead to a considerable risk reduction. In certain circumstances such upgrading is the least expensive option even though the total cost is much higher than the initial plant construction cost. (6) Properly upgraded, the reactor units may be operable until better power resources are available within the country. (7) The existing gap between the technological and political judgements of nuclear safety should be reduced continuously by information exchange improvements. (8) A unified approach to nuclear safety should be adopted for all nuclear reactors (not just WWERs) built to earlier standards. 5 tabs., 1 fig

  12. Earlier Snowmelt Changes the Ratio Between Early and Late Season Forest Productivity

    2017-12-01

    Future projections of declining snowpack and increasing potential evaporation associated with climate warming are predicted to advance the timing of snowmelt in mountain ecosystems globally. This scenario has direct implications for snowmelt-driven forest productivity, but the net effect of temporally shifting moisture dynamics is unknown with respect to the annual carbon balance. Accordingly, this study uses both satellite- and tower-based observations to document the forest productivity response to snowpack and potential evaporation variability between 1989 and 2012 throughout the southern Rocky Mountain ecoregion, USA. These results show that a combination of low snow accumulation and record high potential evaporation in 2012 resulted in the 34-year minimum ecosystem productivity that could be indicative of future conditions. Moreover, early and late season productivity were significantly and inversely related, suggesting that future shifts toward earlier or reduced snowmelt could increase late-season moisture stress to vegetation and thus restrict productivity despite a longer growing season. This relationship was further subject to modification by summer precipitation, and the controls on the early/late season productivity ratio are explored within the context of ecosystem carbon storage in the future. Any perturbation to the carbon cycle at this scale represents a potential feedback to climate change since snow-covered forests represent an important global carbon sink.

    Full Text Available OBJECTIVES: cigarette smoking has been the modifiable risk factor most consistently associated with earlier menopause. This preliminary study based on cross-sectional data aimed to analyze the association between smoking status and age of onset of menopause in a Brazilian population. METHODS: a cross-sectional study was carried out with 1,222 female employees of Rio de Janeiro university campuses aged over 35 years who were at risk of natural menopause. A Cox proportional hazards model was used to investigate the association between smoking status and age at the onset of menopause, adjusting for education, parity and alcohol consumption. RESULTS: current smokers showed a 56% increase in the risk of menopause, being 1.8 years younger at menopause onset compared with women who had never smoked. However, no differences were observed between former smokers and women who had never smoked. The adjusted median age at menopause was 49.5 years for current smokers and 51.3 years for women who had never smoked (p<0.05. CONCLUSIONS: the results suggest a deleterious but potentially reversible effect of smoking on the age of onset of menopause, which should receive greater attention in tobacco control efforts. Longitudinal analyses of this association will be carried out in the future in a follow-up study of this population.

    Full Text Available Emergence is a term used in many contexts in current science; it has become fashionable. It has a traditional usage in philosophy that started in 1875 and was expanded by J. S. Mill (earlier, under a different term and C. D. Broad. It is this form of emergence that I am concerned with here. I distinguish it from uses like ‘computational emergence,’ which can be reduced to combinations of program steps, or its application to merely surprising new features that appear in complex combinations of parts. I will be concerned specifically with ontological emergence that has the logical properties required by Mill and Broad (though there might be some quibbling about the details of their views. I restrict myself to dynamical systems that are embodied in processes. Everything that we can interact with through sensation or action is either dynamical or can be understood in dynamical terms, so this covers all comprehensible forms of emergence in the strong (nonreducible sense I use. I will give general dynamical conditions that underlie the logical conditions traditionally assigned to emergence in nature.The advantage of this is that, though we cannot test logical conditions directly, we can test dynamical conditions. This gives us an empirical and realistic form of emergence, contrary those who say it is a matter of perspective.

    Congenital heart disease (CHD) accounts for a major proportion of disease in the pediatric age group. The objective of the study was to estimate the cost of illness associated with CHD pre, intra and postoperatively; among patients referred to a tertiary care hospital in Karachi, Pakistan. This is the first study conducted to estimate the cost of managing CHD in Pakistan. A prevalence based cost of illness study design was used to estimate the cost of cardiac surgery (corrective & palliative) for congenital heart defects in children ≤ 5 years of age from June 2006 to June 2009. A total of 120 patients were enrolled after obtaining an informed consent and the data was collected using a pre-tested questionnaire. The mean age at the time of surgery in group A (1-12 mo age) was 6.08 ± 2.80 months and in group B (1-5 yrs) was 37.10 ± 19.94 months. The cost of surgical admission was found to be significantly higher in the older group, p = 0.001. The total number and cost of post-operative outpatient visits was also higher in group B, p = 0.003. Pre and post operative hospital admissions were not found to be significantly different among the two groups, p = 0.166 and 0.627, respectively. The number of complications were found to be different between the two groups (p = 0.019). Majority of these were contributed by hemorrhage and post-operative seizures. This study concluded that significant expenditure is incurred by people with CHD; with the implication that resources could be saved by earlier detection and awareness campaigns.

  18. Selection for earlier flowering crop associated with climatic variations in the Sahel.

    Directory of Open Access Journals (Sweden)

    Yves Vigouroux

    Full Text Available Climate changes will have an impact on food production and will require costly adaptive responses. Adapting to a changing environment will be particularly challenging in sub-Saharan Africa where climate change is expected to have a major impact. However, one important phenomenon that is often overlooked and is poorly documented is the ability of agro-systems to rapidly adapt to environmental variations. Such an adaptation could proceed by the adoption of new varieties or by the adaptation of varieties to a changing environment. In this study, we analyzed these two processes in one of the driest agro-ecosystems in Africa, the Sahel. We performed a detailed study in Niger where pearl millet is the main crop and covers 65% of the cultivated area. To assess how the agro-system is responding to recent recurrent drought, we analyzed samples of pearl millet landraces collected in the same villages in 1976 and 2003 throughout the entire cultivated area of Niger. We studied phenological and morphological differences in the 1976 and 2003 collections by comparing them over three cropping seasons in a common garden experiment. We found no major changes in the main cultivated varieties or in their genetic diversity. However, we observed a significant shift in adaptive traits. Compared to the 1976 samples, samples collected in 2003 displayed a shorter lifecycle, and a reduction in plant and spike size. We also found that an early flowering allele at the PHYC locus increased in frequency between 1976 and 2003. The increase exceeded the effect of drift and sampling, suggesting a direct effect of selection for earliness on this gene. We conclude that recurrent drought can lead to selection for earlier flowering in a major Sahelian crop. Surprisingly, these results suggest that diffusion of crop varieties is not the main driver of short term adaptation to climatic variation.

    To assess whether non invasive blood flow measurement by arterial spin labeling in several brain regions detects minimal hepatic encephalopathy. Blood flow (BF) was analyzed by arterial spin labeling (ASL) in different brain areas of 14 controls, 24 cirrhotic patients without and 16 cirrhotic patients with minimal hepatic encephalopathy (MHE). Images were collected using a 3 Tesla MR scanner (Achieva 3T-TX, Philips, Netherlands). Pulsed ASL was performed. Patients showing MHE were detected using the battery Psychometric Hepatic Encephalopathy Score (PHES) consisting of five tests. Different cognitive and motor functions were also assessed: alterations in selective attention were evaluated using the Stroop test. Patients and controls also performed visuo-motor and bimanual coordination tests. Several biochemical parameters were measured: serum pro-inflammatory interleukins (IL-6 and IL-18), 3-nitrotyrosine, cGMP and nitrates+nitrites in plasma, and blood ammonia. Bivariate correlations were evaluated. In patients with MHE, BF was increased in cerebellar hemisphere (P = 0.03) and vermis (P = 0.012) and reduced in occipital lobe (P = 0.017). BF in cerebellar hemisphere was also increased in patients without MHE (P = 0.02). Bimanual coordination was impaired in patients without MHE (P = 0.05) and much more in patients with MHE (P battery and with CFF. BF in cerebellar hemisphere correlates with plasma cGMP and nitric oxide (NO) metabolites. BF in vermis cerebellar also correlates with NO metabolites and with 3-nitrotyrosine. IL-18 in plasma correlates with BF in thalamus and occipital lobe. Non invasive BF determination in cerebellum using ASL may detect MHE earlier than the PHES. Altered NO-cGMP pathway seems to be associated to altered BF in cerebellum.

  20. Analysis of radioactive corrosion test specimens by means of ICP-MS. Comparison with earlier methods

    International Nuclear Information System (INIS)

    Forsyth, Roy

    1997-07-01

    In June 1992, an ICP-MS instrument (Inductively Coupled Plasma-Mass Spectrometry) was commissioned for use with radioactive sample solutions at Studsvik Nuclear's Hot Cell Laboratory. For conventional environmental samples the instrument permits the simultaneous analysis of many trace elements, but the software used in evaluation of the mass spectra is based on a library of isotopic compositions relevant only for elements in the lithosphere. Fission products and actinides, however, have isotopic compositions which are significantly different from the natural elements, and which also vary with the burnup of the nuclear fuel specimen. Consequently, a spread-sheet had to be developed which could evaluate the mass spectra with these isotopic compositions. Following these preparations, a large number of samples (about 200) from SKB's experimental programme for the study of spent fuel corrosion have been analyzed by the ICP-MS technique. Many of these samples were archive solutions of samples which had been taken earlier in the programme. This report presents a comparison of the analytical results for uranium, plutonium, cesium, strontium and technetium by both the ICP-MS technique, and the previously used analytical methods. For three products, a satisfactory agreement between the results from the various methods was obtained, but for uranium and plutonium the ICP-MS method gave results which were 10-20% higher than the conventional methods. The comparison programme has also shown, not unexpectedly, that significant losses of plutonium from solution had occurred, by precipitation and/or absorption, in the archive solutions during storage. It can be expected that such losses also occur for the other actinides, and consequently, all the analytical results for actinides in older archive solutions must be treated with great caution. 9 refs

  1. Metamorphosis Is Ancestral for Crown Euarthropods, and Evolved in the Cambrian or Earlier.

    Wolfe, Joanna M

    2017-09-01

    Macroevolutionary developmental biology employs fossilized ontogenetic data and phylogenetic comparative methods to probe the evolution of development at ancient nodes. Despite the prevalence of ecologically differentiated larval forms in marine invertebrates, it has been frequently presumed that the ancestors of arthropods were direct developers, and that metamorphosis may not have evolved until the Ordovician or later. Using fossils and new dated phylogenies, I infer that metamorphosis was likely ancestral for crown arthropods, contradicting this assumption. Based on a published morphological dataset encompassing 217 exceptionally preserved fossil and 96 extant taxa, fossils were directly incorporated into both the topology and age estimates, as in "tip dating" analyses. Using data from post-embryonic fossils representing 25 species throughout stem and crown arthropod lineages (as well as most of the 96 extant taxa), characters for metamorphosis were assigned based on inferred ecological changes in development (e.g., changes in habitat and adaptive landscape). Under all phylogenetic hypotheses, metamorphosis was supported as most likely ancestral to both ecdysozoans and euarthropods. Care must be taken to account for potential drastic post-embryonic morphological changes in evolutionary analyses. Many stem group euarthrpods may have had ecologically differentiated larval stages that did not preserve in the fossil record. Moreover, a complex life cycle and planktonic ecology may have evolved in the Ediacaran or earlier, and may have typified the pre-Cambrian explosion "wormworld" prior to the origin of crown group euarthropods. © The Author 2017.

    Full Text Available Introduction: Increasing attention has been focused on parental leave, but little is known about early leave and parental experiences for male and female attending physicians. Our goal was to describe and quantify the parental leave experiences of a nationally representative sample of emergency physicians (EP. Methods: We conducted a web-based survey, distributed via emergency medicine professional organizations, discussion boards, and listservs, to address study objectives. Results: We analyzed data from 464 respondents; 56% were women. Most experienced childbirth while employed as an EP. Fifty-three percent of women and 60% of men reported working in a setting with a formal maternity leave policy; however, 36% of women and 18% of men reported dissatisfaction with these policies. Most reported that other group members cover maternity-related shift vacancies; a minority reported that pregnant partners work extra shifts prior to leave. Leave duration and compensation varied widely, ranging from no compensated leave (18% to 12 or more weeks at 100% salary (7%. Supportive attitudes were reported during pregnancy (53% and, to a lesser degree (43%, during leave. Policy improvement suggestions included the development of clear, formal policies; improving leave duration and compensation; adding paternity and adoption leave; providing support for physicians working extra to cover colleagues’ leave; and addressing breastfeeding issues. Conclusion: In this national sample of EPs, maternity leave policies varied widely. The duration and compensation during leave also had significant variation. Participants suggested formalizing policies, increasing leave duration and compensation, adding paternity leave, and changing the coverage for vacancies to relieve burden on physician colleagues.

    Introduction Increasing attention has been focused on parental leave, but little is known about early leave and parental experiences for male and female attending physicians. Our goal was to describe and quantify the parental leave experiences of a nationally representative sample of emergency physicians (EP). Methods We conducted a web-based survey, distributed via emergency medicine professional organizations, discussion boards, and listservs, to address study objectives. Results We analyzed data from 464 respondents; 56% were women. Most experienced childbirth while employed as an EP. Fifty-three percent of women and 60% of men reported working in a setting with a formal maternity leave policy; however, 36% of women and 18% of men reported dissatisfaction with these policies. Most reported that other group members cover maternity-related shift vacancies; a minority reported that pregnant partners work extra shifts prior to leave. Leave duration and compensation varied widely, ranging from no compensated leave (18%) to 12 or more weeks at 100% salary (7%). Supportive attitudes were reported during pregnancy (53%) and, to a lesser degree (43%), during leave. Policy improvement suggestions included the development of clear, formal policies; improving leave duration and compensation; adding paternity and adoption leave; providing support for physicians working extra to cover colleagues’ leave; and addressing breastfeeding issues. Conclusion In this national sample of EPs, maternity leave policies varied widely. The duration and compensation during leave also had significant variation. Participants suggested formalizing policies, increasing leave duration and compensation, adding paternity leave, and changing the coverage for vacancies to relieve burden on physician colleagues.

    Despite several policies aimed at increasing fathers' participation in the caring of children, Swedish mothers still use the bulk of the paid parental leave which may have several negative consequences for the family e.g. in terms of weaker labor market attachment for the mother. Division of parental leave is likely affected by how parents value the costs associated with parental leave. I investigate whether a reduction in the care burden, or a decreased non-monetary cost, of parental leave t...

    Leaves show a variety of strategies for maximizing CO{sub 2} and light capture. These are more meaningfully explained if they are considered in the context of maximizing capture relative to the utilization of water, nutrients and carbohydrates reserves. There is considerable variation between crops in their efficiency of CO{sub 2} and light capture at the leaf level. Understanding of these mechanisms indicate some ways in which efficiency of resource capture could be level cannot be meaningfully considered without simultaneous understanding of implications at the canopy level. 36 refs., 5 figs., 1 tab.

    Sladek, Carol

    While the United States continues to be the only developed nation without mandated paid maternity leave, U.S. employers are blazing their own trail for new parents. This article defines parental leave, explains what's driving the increased interest in paid parental leave among employers offering it and discusses how paid parental leave can benefit employers and employees alike. Finally, the author discusses why not all employers are offering these benefits as well as considerations for employers contemplating whether paid parental leave is right for them.

    Saccades bring objects of interest onto the fovea for high-acuity processing. Saccades to rewarded targets show shorter latencies that correlate negatively with expected motivational value. Shorter latencies are also observed when the saccade target is relevant for a perceptual discrimination task. Here we tested whether saccade preparation is equally influenced by informational value as it is by motivational value. We defined informational value as the probability that information is task-relevant times the ratio between postsaccadic foveal and presaccadic peripheral discriminability. Using a gaze-contingent display, we independently manipulated peripheral and foveal discriminability of the saccade target. Latencies of saccades with perceptual task were reduced by 36 ms in general, but they were not modulated by the information saccades provide (Experiments 1 and 2). However, latencies showed a clear negative linear correlation with the probability that the target is task-relevant (Experiment 3). We replicated that the facilitation by a perceptual task is spatially specific and not due to generally heightened arousal (Experiment 4). Finally, the facilitation only emerged when the perceptual task is in the visual but not in the auditory modality (Experiment 5). Taken together, these results suggest that saccade latencies are not equally modulated by informational value as by motivational value. The facilitation by a perceptual task only arises when task-relevant visual information is foveated, irrespective of whether the foveation is useful or not.

    Full Text Available The influence of an Uncaria tomentosa extract on the development of Capsicum plants grown in green-house conditions was examined. The effect of the treatment was investigated with microscopic techniques (light and electron microscope in leaves from three levels of control plants and plants after treatment with the extract added to the soil in doses of 0.4 and 16 mg/ml (200 ml per pot/plant. In control leaves, changes typical of the subsequent phases of normal development were observed: nuclear chromatin became slightly condensed, plastoglobuli of chloroplasts increased in number and size, intragranal thylakoids were somewhat dilatated. In addition to such commonly occurring changes, some symptoms typical of pepper were observed in the ontogenesis of the examined plant: an increased number of spherical electron-dense deposits in vacuoles, an increased number of peroxisomes, the occurrence of numerous paracrystalline structures in chloroplasts of mature leaves, and, starting in mature leaves, expulsion of plastoglobuli from chloroplasts. After the treatment, most of those changes, leading to ageing, occurred much earlier and were more distinct. Chloroplasts, already in the youngest examined leaves, showed dilatation of intergranal thylakoids, which intensified with aging of the leaves and degradation of grana in the oldest leaves. Starch grains decreased in size and number and plastoglobuli became large. Vesiculation of ground cytoplasm in all leaves was stronger than in the control. No paracrystalline structures in chloroplasts or expulsion of plastoglobuli were observed. Another unusual phenomenon was the disappearance of spherical electron-dense deposits in the central vacuoles of cells. Those observations suggested that U. tomentosa extract enhanced the natural ontogenesis of Capsicum annuum leaves, by accelerating and enhancing the typical characteristics of ageing, and, additionally, it changed the structure and physiology of cells.

    2011-08-01

    To investigate sick leave and disability pension in rheumatoid arthritis (RA) in relation to the initiation of biological and non-biological antirheumatic therapies in clinical practice. Patients aged 19-60 years initiating non-biological mono (n=2796) or combination disease-modifying antirheumatic drug (DMARD) therapy (n=973), or biological agents (n=4787) were identified in the Swedish Rheumatology Quality Register between 1999 and 2007. Sick leave and disability pension data (1995-2010) were retrieved from national registers. During the year before the start of mono DMARD, combination DMARD and biological treatment, 10%, 12% and 43% of patients received disability pension benefits, respectively. The corresponding combined annual sick leave and disability pension days were 78 (54+25), 132 (105+27) and 190 (79+111). Irrespective of treatment type, initiators were characterised by a history of increasing sick leave and disability pension. Treatment start was associated with a break in this trajectory: sick leave decreased while disability pension increased, resulting in a net stabilisation of total days. Higher levels of days on sick leave and disability pension at treatment start were observed in patients initiating biologics in 1999 (236 days/year) compared with 2007 (150 days/year; ppension increased rapidly before the initiation of antirheumatic therapy, which was associated with a halt but not a reversal of this development. Work ability is a metric of importance for clinical practice, signalling large remaining needs in the RA population, and the need for intervention earlier in the disease process.

  20. Laboring Until Labor: The Prevalence and Correlates of Antenatal Maternity Leave in the United States.

    Goodman, Julia M

    2018-02-01

    Introduction Most women in the U.S. are employed during pregnancy and work until the month of childbirth. For many, working throughout pregnancy poses little threat to their health; however, women experiencing difficult pregnancies and/or working in strenuous or inflexible jobs may benefit from taking time from work as they approach childbirth, but almost no empirical evidence examines antenatal leave (ANL). Methods Using a national survey of English-speaking women, this paper offers the first national description of ANL and examines state policy predictors of uptake. Results Thirty-seven percent of employed women worked until the week their baby was due. After controlling for characteristics of women and their jobs, living in a state with any or multiple leave laws increased the probability of ANL by 14 and 23% points, respectively. Women living in states with multiple leave laws stopped work almost 2 weeks earlier than women in states without a policy. Discussion Paid leave policies currently being considered at the federal, state, and local levels should consider the potential impact on antenatal leave, in addition to postnatal leave, and how they influence population health.

    Full Text Available Aqueous infusions of the leaves of the shrub Albertisia delagoensis (Menispermaceae are used in South Africa in traditional Zulu medicine to alleviate a variety of symptoms, including fever, and intestinal problems. We report the analysis of such an aqueous extract using the HPLC-NMR technique. A number of polar compounds were identified, including proto-quercitol, nicotinic acid, allantoic acid, 3,4-dihydroxy-benzoic acid, phthalic acid and the aporphine alkaloid derivative roemrefidine. Allantoic acid and roemrefidine have been fully characterised by 1H- and 13C-NMR and mass spectrometry. Earlier reports of antiplasmodial activity of roemrefidine and of A. delagoensis extracts are correlated with this study and with the antipyretic properties of neutral aqueous extracts.

    2013-10-01

    This study assesses NHS doctors' experiences of paternity leave and evaluates whether practices have changed since the introduction of additional paternity leave (APL) in April 2011. An anonymised online survey designed to discover experiences and uptake of APL and ordinary paternity leave (OPL) was distributed to all members of the London Deanery Synapse® network. In total, 364 fathers responded. Their seniority ranged from foundation trainees to consultants. Following the formal introduction of OPL in 2003, the number of fathers taking any paternity leave increased (from 50% to 95.6%). The majority of respondents (76.7%) felt well supported by their employer. Since the introduction of APL, 3% of respondents took additional leave. Reasons for the low uptake of APL included the impracticalities of the law, poor awareness and perceived attitudes and implications for training. Problems with OPL included the inadequate provision of cover and difficulties in timing the leave appropriately.

    Despite the benefits of breastfeeding, rates in the United States are low. Shorter maternity leave is associated with lower initiation and shorter durations of breastfeeding; however, little is known about how paid maternity leave may influence breastfeeding rates. We used data from the 2006-2010 U.S. National Survey of Family Growth on the most recent birth to employed women who delivered a child within the previous 5 years. Separate multivariable logistic regression models were used to describe the associations between paid leave duration (0, 1-5, 6-11, ≥ 12 weeks, maternity leave not taken) and three outcomes: 1) breastfeeding initiation, 2) 6-month duration, and 3) 6-month duration among initiators. Twenty-eight percent of prenatally employed women received no paid leave. Women who received 12 or more weeks of paid leave were more likely to initiate breastfeeding compared to women with no paid leave (87.3% vs 66.7%, adjusted odds ratio [aOR] 2.83 [95% confidence interval {CI} 1.23-6.48]). Similarly, women with 12 or more weeks of paid leave were more likely to breastfeed at 6 months, compared to women with no paid leave (24.9% vs 50.1%, aOR 2.26 [95% CI 1.20-4.26]). Among women who initiated breastfeeding, having received 12 or more weeks' paid leave increased the odds of breastfeeding for 6 or more months; however, the association was not statistically significant in the adjusted model (aOR 1.81 [95% CI 0.93-3.52]). Employed women who received 12 or more weeks of paid maternity leave were more likely to initiate breastfeeding and be breastfeeding their child at 6 months than those without paid leave.

    2008-05-01

    This paper is a report of a study to investigate how nurses' work values, perceptions of environmental characteristics, and organizational commitment are related to their leaving intentions. Nurse leaving is a serious international problem as it contributes to the nursing shortage that threatens the welfare of society. The characteristics of nurses, the work environment and nurses' feelings towards their jobs (or organizations) have an impact on their leaving intentions. A convenience sample of 849 Registered Nurses was recruited from three public hospitals in the central-west region of Japan during 2006 and 319 completed questionnaires were returned (response rate 39%). Data were analysed using regression analysis. Nurses' work values and their perceptions of their workplace environment interacted to influence leaving intentions. When there was a match between the importance nurses placed on being able to challenge current clinical practices and the number of the actual opportunities to do so, leaving intentions were low. When there was a mismatch, intention to quit the job became stronger. In addition, organizational commitment intervened between nurses' perceptions of the match in clinical challenges and leaving intention. Nurses' leaving intentions, deserve extensive exploration of their causes. Such exploration should include attending to both nurses' needs and organizational characteristics, investigating how the match between them could affect nurses' leaving intention, and exploring factors that intervene between nurses' perceptions of the match and leaving intention.

  10. Nucleofugalities of Neutral Leaving Groups in 80 % Aqueous Acetonitrile

    Directory of Open Access Journals (Sweden)

    Full Text Available Nucleofugalites of tetrahydrothiophene, dimethyl sulfide and differently substituted pyridines in 80 % aqueous acetonitrile have been derived from the SN1 solvolysis rate constants of the corresponding X,Y-substituted benzhydryl derivatives (1–10. In sol-volysis of sulfonium ions in 80 % aqueous acetonitrile, where acetonitrile is a good cation solvator, the solvation of the reactant ground state is an important rate determining variable since the positive charge is almost entirely located on the leaving group. As a consequence, reaction rates of sulfonium ions are more sensitive to the substrate structure in 80 % aqueous acetonitrile than in pure and aqueous alcohols, which are less efficient as cation solvators. In solvolysis of pyridinium ions the solvation of the reactant ground state is less important, since the positive charge is considerably distributed between the carbon at the reaction center and the leaving group. In such cases the important rate determining variable is solvation of the transition state. Slower reactions of pyridinium sub-strates progress over later, carbocation-like transition states in which the solvation is more important, so those substrates solvolyze slightly faster in aqueous acetonitrile than in methanol (k80AN > kM. Faster reactions proceed over earlier TS in which the solvation is diminished, so those substrates solvolyze somewhat faster in methanol than in aqueous acetonitrile (k80AN kM.

    Parents of children with special health care needs are especially vulnerable to work-family conflicts that family leave benefits might help resolve. We examined leave-taking among full-time-employed parents of children with special health care needs. We identified all children with special health care needs in 2 large inpatient/outpatient systems in Chicago, Illinois, and Los Angeles, California, and randomly selected 800 per site. From November 2003 to January 2004, we conducted telephone interviews with 1105 (87% of eligible and successfully contacted) parents. Among the sample's 574 full-time-employed parents, we examined whether leave benefits predicted missing any work for child illness, missing >4 weeks for child illness, and ability to miss work whenever their child needed them. Forty-eight percent of full-time-employed parents qualified for federal Family and Medical Leave Act benefits; 30% reported employer-provided leave benefits (not including sick leave/vacation). In the previous year, their children averaged 20 missed school/child care days, 12 doctor/emergency department visits, and 1.7 hospitalizations. Although 81% of parents missed work for child illness, 41% reported not always missing work when their child needed them, and 40% of leave-takers reported returning to work too soon. In multivariate regressions, parents who were eligible for Family and Medical Leave Act benefits and aware of their eligibility had 3.0 times greater odds of missing work for child illness than ineligible parents. Parents with >4 weeks of employer-provided leave benefits had 4.7 times greater odds of missing >4 weeks than parents without benefits. Parents with paid leave benefits had 2.8 times greater odds than other parents of missing work whenever their child needed them. Full-time-employed parents of children with special health care needs experience severe work-family conflicts. Although most have leave benefits, many report unmet need for leave.

    To explore the factors that predict the retention of nurses working in emergency departments. The escalating shortage of nurses is one of the most critical issues facing specialty areas, such as the emergency department. Therefore, it is important to identify the key influencing and intermediary factors that affect emergency department nurses' intention to leave. As part of a larger study, a cross-sectional survey was completed by 261 registered nurses working in the 12 designated emergency departments within rural, urban community and tertiary hospitals in Manitoba, Canada. Twenty-six per cent of the respondents will probably/definitely leave their current emergency department jobs within the next year. Engagement was the key predictor of intention to leave (P burnout (P nursing management, professional practice, collaboration with physicians, staffing resources and shift work emerged as significant influencing factors for engagement. Engagement plays a central role in emergency department nurses intention to leave. Addressing the factors that influence engagement may reduce emergency department nurses' intention to leave. This study highlights the value of research-based evidence as the foundation for developing innovative strategies for the retention of emergency department nurses. © 2012 Blackwell Publishing Ltd.

  13. Seasonal changes in photosynthetic capacity of leaves of kiwifruit (Actinidia deliciosa) vines

    1991-01-01

    The seasonal trend of photosynthetic capacity of leaves of kiwifruit (Actinidia deliciosa var. deliciosa) vines growing in the field was examined, by measuring the response of net photosynthesis (A) to irradiance (PAR) at monthly intervals for leaves that emerged at different stages of the growing season. A climate controlled minicuvette system was used, to ensure constant environmental conditions, apart from the controlled changes in leaf irradiance. Responses of A to irradiance were described using asymptotic exponential curves, providing estimates of the radiation saturated rate of A (A sat ), and the response of A to increasing incident PAR at low PAR levels (ϕ i ). The change in photosynthetic capacity with leaf age was similar for leaves emerging 1, 2, 3 or 4 months after bud burst. At 1 month after leaf emergence, when leaves were fully expanded, Asat was 9–11 μmol CO 2 m −2 s −1 . Maximum photosynthetic capacity was not attained until 3–5 months after leaf emergence, when Asat was 16–17 μmol CO 2 m −2 s −1 . The increasing photosynthetic capacity during 3–5 months after leaf emergence was closely related to concomitant changes in leaf N and chlorophyll contents. The possibility that N import to the leaf was a significant factor limiting the development of photosynthetic capacity is discussed. (author)

    2014-04-01

    Our earlier investigations showed that Elodea canadensis shoots, grown in the presence of cadmium (Cd), caused basification of the surrounding medium. The present study was aimed to examine the proton dynamics of the apoplastic, cytosolic and vacuolar regions of E. canadensis leaves upon Cd exposure and to establish possible linkage between cellular pH changes and the medium basification. The changes in cytosolic calcium [Ca(2+)]cyt was also investigated as the [Ca(2+)]cyt and [pH]cyt homeostasis are closely linked. The cellular H(+) and Ca(2+) concentrations were monitored by fluorescence microscopy and ion-specific fluorescent dyes. Cadmium concentration of leaf-cell walls was measured after plant cultivation at different fixed levels of starting pH. The protoplasts from E. canadensis leaves were isolated by use of a newly developed enzymatic method. Upon Cd addition, both cytosolic and vacuolar pH of leaf protoplasts increased with a concomitant rise in the cytosolic Ca(2+) concentration. Time course studies revealed that changes in [Ca(2+)]cyt and [pH]cyt followed similar dynamics. Cadmium (0.5 μM) exposure decreased the apoplastic pH by 0.85 units. The maximum cell wall bound Cd-contents were obtained in plants grown at low starting pH. It is concluded that Cd treatment causes apoplastic acidosis in E. canadensis leaves associated with enhanced Cd binding to the cell walls and, consequently, reduced Cd influx into the cytosol.

    Discussions about early hominin diets have generally excluded grass leaves as a staple food resource, despite their ubiquity in most early hominin habitats. In particular, stable carbon isotope studies have shown a prevalent C 4 component in the diets of most taxa, and grass leaves are the single most abundant C 4 resource in African savannas. Grass leaves are typically portrayed as having little nutritional value (e.g., low in protein and high in fiber) for hominins lacking specialized digestive systems. It has also been argued that they present mechanical challenges (i.e., high toughness) for hominins with bunodont dentition. Here, we compare the nutritional and mechanical properties of grass leaves with the plants growing alongside them in African savanna habitats. We also compare grass leaves to the leaves consumed by other hominoids and demonstrate that many, though by no means all, compare favorably with the nutritional and mechanical properties of known primate foods. Our data reveal that grass leaves exhibit tremendous variation and suggest that future reconstructions of hominin dietary ecology take a more nuanced approach when considering grass leaves as a potential hominin dietary resource.

    Full Text Available The development of appropriate weed management strategies and efficient use of herbicides relies upon understanding weed-crop interactions. A field study was carried out to assess the effect of weed interference on leaves, internode and harvest index of dry bean (Phaseolus vulgaris L.. The experiment was established under a randomized complete block design with two types of weed interference treatments: plots with weeds and plots without weeds at different time intervals (0, 10, 20, 30, 40 and 50 days after crop emergence. The sigmoid Boltzmann model was used to quantify the crop traits as influenced by weed interference. Prolonged delays in weed removal reduced gradually the number of leaves of the crop. Weed interference decreased dry weight of leaves as well, so that the lowest value of it (33.49 g plant-1 was observed in full season during weed-infested treatment. Infestation of weeds affected the length of the crop internodes. While the weed interference duration increased, the length of the internodes decreased. Harvest index was also sensitive to weed competition. As the crop was kept weed-infested from the emergence for increasing periods of time, harvest index decreased to a value of 28.01%. A significant negative correlation between total biomass of weeds and dry bean traits (number of leaves, leaves dry weight, internode length and harvest index was observed. Therefore, weeds are able to adversely affect dry bean growth through constraining environmental resources and impairing leaves as the photosynthetic areas.

    To identify the contribution of the duration of the prenatal maternity leave on term delivery. Characteristics of the prenatal maternity leave and delivery among 363 working women who had delivered a full-term infant at 1 of 4 hospitals in Montreal during 1996 were studied. The presence of an intervention or complication during delivery was observed in 68.9% of the participants. The average duration of the prenatal maternity leave was about 8 weeks (SD = 7). The adjusted risk of a difficult delivery decreased significantly with the duration of the prenatal maternity leave (OR = 0.96; 95% CI: 0.93-0.99). The duration of the maternity leave before delivery is associated with an easier term delivery for working women.

    Many nurses leave nursing and never return. Others return after a period of time. Given the global shortage of nurses a better understanding of these movements is needed. The present study focused on nurses who had been out of nursing for more than five years, and explored factors that influenced their leaving and return to practice. All the nurses who had undertaken a Competency Assessment Programme at a given New Zealand tertiary institution during 2005 were invited to participate. Of the 70 questionnaires mailed out 32 (44.5%) were completed and returned. Quantitative data were analysed using Microsoft Excel, and the qualitative data were coded and analysed by means of content analysis. For each, leaving and returning, three key issues emerged. Nurses left for personal reasons, to seek a career change, or because of poor working conditions. They returned when they had the personal freedom to do so, for fiscal reasons, or because they were motivated by some sense of unfinished business. These findings indicate that it is important for educators involved with Competency Assessment Programmes to collaborate with employers in ensuring that there are opportunities for re-entry to positive work environments, with a degree of flexibility that suits the demographic characteristics of those nurses returning to practice.

    The temporo-spatial relationship between the three organs (lung, spleen and lymph node) involved during the initial stages of Mycobacterium tuberculosis infection has been poorly studied. As such, we performed an experimental study to evaluate the bacillary load in each organ after aerosol or intravenous infection and developed a mathematical approach using the data obtained in order to extract conclusions. The results showed that higher bacillary doses result in an earlier IFN-γ response, that a certain bacillary load (BL) needs to be reached to trigger the IFN-γ response, and that control of the BL is not immediate after onset of the IFN-γ response, which might be a consequence of the spatial dimension. This study may have an important impact when it comes to designing new vaccine candidates as it suggests that triggering an earlier IFN-γ response might not guarantee good infection control, and therefore that additional properties should be considered for these candidates.

    Full Text Available Background: Age at symptom onset (ASO is a prognostic factor that could affect the accrual of disability in multiple sclerosis (MS patients. Some factors are known to influence the risk of multiple sclerosis (MS, but their influence on the ASO is less well-investigated.Objective: Examine the associations between known or emerging MS risk factors and ASO.Methods: This was a multicenter study, incident cases (n = 279 with first clinical diagnosis of demyelinating event aged 18–59 years recruited at four Australian centres (latitudes 27°-43°S, from 1 November 2003 to 31 December 2006. Environmental/behavioral variables and initial symptoms were recorded at baseline interview. Linear regression was used to assess the association between risk factors and ASO.Results: Five factors were significantly associated with ASO: a history of tobacco smoking was associated with 3.05-years later ASO (p = 0.002; a history of marijuana use was associated with 6.03-years earlier ASO (p < 0.001; progressive-onset cases had 5.61-years later ASO (p = 0.001; an initial presentation of bowel & bladder and cerebral dysfunctional were associated with 3.39 (p = 0.017 and 4.37-years (p = 0.006 later ASO, respectively. Other factors, including sex, offspring number, latitude of study site, history of infectious mononucleosis, HLA-DR15 & HLA-A2 genotype, 25(OHD levels, and ultraviolet radiation exposure were not associated with ASO. Including all five significant variables into one model explained 12% of the total variance in ASO.Conclusion: We found a novel association between a history of tobacco smoking and later onset, whereas marijuana use was associated with earlier onset. Behavioral factors seem important drivers of MS onset timing although much of the variance remains unexplained.

    Cannabis use is associated with an earlier age of onset of psychosis (AOP). However, the reasons for this remain debated. Methods: We applied a Cox proportional hazards model to 410 first-episode psychosis patients to investigate the association between gender, patterns of cannabis use, and AOP. Results: Patients with a history of cannabis use presented with their first episode of psychosis at a younger age (mean years = 28.2, SD = 8.0; median years = 27.1) than those who never used cannabis (mean years = 31.4, SD = 9.9; median years = 30.0; hazard ratio [HR] = 1.42; 95% CI: 1.16–1.74; P cannabis at age 15 or younger had an earlier onset of psychosis (mean years = 27.0, SD = 6.2; median years = 26.9) than those who had started after 15 years (mean years = 29.1, SD = 8.5; median years = 27.8; HR = 1.40; 95% CI: 1.06–1.84; P = .050). Importantly, subjects who had been using high-potency cannabis (skunk-type) every day had the earliest onset (mean years = 25.2, SD = 6.3; median years = 24.6) compared to never users among all the groups tested (HR = 1.99; 95% CI: 1.50- 2.65; P cannabis had an onset an average of 6 years earlier than that of non-cannabis users. Conclusions: Daily use, especially of high-potency cannabis, drives the earlier onset of psychosis in cannabis users. PMID:24345517

    2013-01-01

    In 2010 the University of Wisconsin - Madison Astronomy Department developed and implemented a departmental paid leave policy for our graduate students, even though the university lacks a campus-wide policy and cannot provide institutional funding for such programs. This policy includes 12 weeks of paid leave in event of a medical emergency or chronic medical condition, as well as paid parental leave for both male and female graduate research assistants. Building on the graduate student perspective of Gosnell (2012), I will discuss the process of this successful development of a departmental family and medical leave policy for graduate students from the perspective of a faculty member and chair. In particular I will discuss implications of university policies, the importance of faculty and staff support, the role of private funds, and issues of effort certification.

    Based on the spectral characters of corn leaf nitrogen content in the space, the spectral models for rapid estimating crop nitrogen content were set up, which is practically meaningful to effectively providing the guidance in fertilization. Spectral technology was applied to explore corn leaves nitrogen content distribution regularity and the relationship between the nitrogen content and plant index was analysed and then the estimation models were built. The results showed N content in upper leaves is higher than that in lower leaves in four growing stages; lower leaves at tassel emerge stage are sensitive to nitrogen losses, which could be used in guiding fertilization in grain production; optimum estimation models were built atjointing stage, the full-grown stage and tasseling stage, The research results provided the proof of crop nutrient analysis and rational fertilization.

    Longitudinal growth data of children were analyzed to clarify the relationship between the timing of body mass index (BMI) rebound and obesity risk in later ages. Of 54 558 children born between April 2004 and March 2005 and longitudinally measured in April and October every year in the preschool period, 15 255 children were analyzed wherein no longitudinal measurement is missing after 1 year of age. BMI rebound age was determined as the age with smallest BMI value across longitudinal individual data after 1 year of age. Rebound age was compared between overweight and non-overweight groups. The subjects were divided into groups based on the timing of rebound. The sex- and age-adjusted mean of the BMI, height and weight s.d. scores for age group, along with 6 months weight and height gain, were compared among groups using analysis of covariance. Among those who were overweight at 66-71 months of age, BMI rebound age obtained at approximately 3 years of age was compared with the non-overweight group, whose BMI rebound age was utmost 66 months or later (PBMI age group showed that earlier BMI rebound results in larger BMI (PBMI rebound earlier than 30 months of age, low BMI was observed (PBMI rebound among groups with rebound age earlier than 60 months of age (PBMI rebound timing with pre-rebound low BMI leads to greater childhood obesity risk; hence, early detection and prevention is necessary for such cases.

    It has previously been shown that breastfeeding may reduce the risk of type 2 diabetes in mothers with recent gestational diabetes mellitus (GDM). This study compared the cessation of predominant breastfeeding in mothers with and without recent GDM in a multi-ethnic population. From May 2008 to May 2010, healthy pregnant women attending antenatal care provided by community health services in Eastern Oslo, Norway were recruited. We included 616 women-58% non-Western-and interviewed and examined them at a mean of 15 and 28 weeks of gestation and 14 weeks' postpartum. Cox regression models examined the association between GDM, as assessed by the 2013 World Health Organization criteria, and breastfeeding cessation. Overall, 190 of the 616 (31%) mothers had GDM and they ended predominant breastfeeding earlier than mothers without GDM, with an adjusted hazard ratio (aHR) of 1.33 and 95% confidence interval (95% CI) of 1.01-1.77. Mothers of South Asian origin ended predominant breastfeeding earlier than Western European mothers in the adjusted analysis (aHR 1.53, 95% CI: 1.04-2.25), but Middle Eastern mothers did not.

    The purpose of the present paper is to model a physical polarimetric bidirectional reflectance distribution function (pBRDF), which can character not only the non-Lambertian but also the polarized features in order that the pBRDF can be applied to analyze the relationship between the degree of polarization and the physiological and biochemical parameters of leaves quantitatively later. Firstly, the bidirectional polarized reflectance distributions from several leaves surfaces were measured by the polarized goniometer developed by Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences. The samples of leaves include two pieces of zea mays L. leaves (young leaf and mature leaf) and a piece of E. palcherrima wild leaf. Non-Lambertian characteristics of directional reflectance from the surfaces of these three leaves are obvious. A Cook-Torrance model was modified by coupling the polarized Fresnel equations to simulate the bidirectional polarized reflectance properties of leaves surfaces. The three parameters in the modified pBRDF model, such as diffuse reflectivity, refractive index and roughness of leaf surface were inversed with genetic algorithm (GA). It was found that the pBRDF model can fit with the measured data well. In addition, these parameters in the model are related with both the physiological and biochemical properties and the polarized characteristics of leaves, therefore it is possible to build the relationships between them later.

    Task 5 of the collaborative effort between ORNL, Brazil, and Westinghouse for the International Nuclear Energy Research Initiative entitled 'Development of Advanced Instrumentation and Control for an Integrated Primary System Reactor' focuses on operator control and protection system interaction, with particular emphasis on developing emergency response guidelines (ERGs). As in the earlier tasks, we will use the IRIS plant as a specific example of an integrated primary system reactor (IPSR) design. The present state of the IRIS plant design--specifically, the lack of a detailed secondary system design--precludes establishing detailed emergency procedures at this time. However, we can create a structure for their eventual development. This report summarizes our progress to date. Section 1.2 describes the scope of this effort. Section 2 compares IPSR ERG development to the recent AP1000 effort, and identifies three key plant differences that affect the ERGs and control room designs. The next three sections investigate these differences in more detail. Section 3 reviews the IRIS Safety-by-Design philosophy and its impact on the ERGs. Section 4 looks at differences between the IRIS and traditional loop PWR I and C Systems, and considers their implications for both control room design and ERG development. Section 5 examines the implications of having one operating staff control multiple reactor units. Section 6 provides sample IRIS emergency operating procedures (EOPs). Section 7 summarizes our conclusions

    To describe the profile of women with children aged under 4 months living in the Brazilian state capitals and in the Federal District according to their working status and to analyze the influence of maternity leave on exclusive breastfeeding (EBF) among working women. This was a cross-sectional study with data extracted from the II National Maternal Breastfeeding Prevalence Survey carried out in 2008. Initially, a descriptive analysis of the profile of 12,794 women was performed, according to their working status and maternity leave and the frequency of maternity leave in the Brazilian regions and capitals. The study used a multiple model to identify the influence of maternity leave on EBF interruption, including 3766 women who declared they were working and were on maternity leave at the time of the interview. The outcome assessed in the study was the interruption of the EBF, classified by the WHO. Regarding the working status of the mothers, 63.4% did not work outside of their homes and among those who worked, 69.8% were on maternity leave. The largest prevalence among workers was of women older than 35 years of age, with more than 12 years of schooling, primiparous and from the Southeast and South regions. The lack of maternity leave increased by 23% the chance of EBF interruption. Maternity leave contributed to increase the prevalence of EBF in the Brazilian states capitals, supporting the importance of increasing the maternity leave period from four to six months.

Results: Regarding the working status of the mothers, 63.4% did not work outside of their homes and among those who worked, 69.8% were on maternity leave. The largest prevalence among workers was of women older than 35 years of age, with more than 12 years of schooling, primiparous and from the Southeast and South regions. The lack of maternity leave increased by 23% the chance of EBF interruption. Conclusion: Maternity leave contributed to increase the prevalence of EBF in the Brazilian states capitals, supporting the importance of increasing the maternity leave period from four to six months.

    In 1996 the Nuclear Regulatory Authority of the Slovak Republic (NRA SR) continued in systematic development of its activities in the field of emergency planning according to the concept adopted by the Authority and according to the concept for building Emergency headquarters (EH) adopted after establishing of Emergency Response Centre (ERC). Major efforts were focused not only on building up a quality EH, but also tasks associated with completion and incorporation of ERC into emergency planning and emergency managing. An important role in building ERC was played by international missions. Significant position among these missions was taken by missions from Great Britain, which in the past years made a significant contribution to building up ERC. These missions focused on review of newly created standard procedures, preparation and implementation of first emergency exercises of the EH. The emergency exercises in which NRA SR took place in 1996 are reviewed. In order to make the co-operation of the Authority with the selected Army units of SR more effective in solving extraordinary situations in nuclear energy, an agreement was signed between NRA SR and the Headquarters of the Army of SR, which will help significantly to the objective

    1998-09-01

    To help recruit and retain physicians, especially women, rural family practice groups need to establish policies regarding maternity and other family leaves. Also important are policies regarding paternity leave, adoptive leave, and leave to care for elderly parents. We surveyed members of the American Academy of Family Physicians in rural practice in 1995 to assess the prevalence of leave policies, the degree to which physicians are taking family leave, and the characteristics of ideal policies. Currently, both men and women physicians are taking family leaves of absence, which indicates a need for leave policies. Furthermore, a lack of family leave policies may deter women from entering rural practice.

    Women account for the majority of parental leave take-up, which is likely one of the major reasons for the gender gap in income and wages. Consequently, many countries exert effort to promote a more gender equal division of parental leave. Indeed, the last decades have seen an increase in fathers' take-up of parental leave benefits, but the gender earnings gap has remained fairly constant. In this paper we re-evaluate the labour supply responses of both mothers and fathers to three major refo...

    Separation from the family, a key developmental task, has received scant attention from developmentalists. In this study, college students' dissimilarity ratings and ratings on 22 bipolar adjective scales were obtained for a set of 20 definitions of home-leaving. Results of a cluster analysis revealed that conceptualizations of the definitions are organized in terms of eight clusters. Ratings on the 22 adjective scales provided an empirical means for interpreting the typological structure of the home-leaving definitions. Convergence the results of this inductive study of home-leaving and elements of ego development theory was noted.

    Laser induced fluorescence (LIF) is successfully used as a technique for remote detection of spectral characteristics of some plants. A pulsed nitrogen laser at 337.1 nm is used to excite cotton, corn and rice leaves. The fluorescence spectrum is detected in the range from 340 nm to 820 nm. It is found that, these plant leaves have common fluorescence maxima at 440 nm, 685 nm and 740 nm. plant leaves are also found to be identifiable by the ratio of the fluorescence intensity at 440 nm to that at 685 nm. The present technique can be further used as a means of assessing, remotely, plant stresses. 5 fig

    In France, most women of childbearing age work. The prenatal leave law in France protects women during pregnancy and their employment. We aimed to describe how long before delivery women stopped working and analyse the association between occupational, social and medical factors and early prenatal leave (before 24 weeks' gestation). The sample was extracted from the 2010 French National Perinatal Survey. Women were interviewed in French maternity units during a 1-week period. We focused on all women with a singleton live birth who were working during pregnancy (n = 10 149). Women were interviewed between delivery and discharge to collect information on employment, date of leave, sociodemographic and medical characteristics. Among women who worked during pregnancy, 27.5% reported early occupational leave (before 24 weeks' gestation). Early occupational leave was more frequent among women with unstable jobs (fixed-term vs. non-fixed-term contract: adjusted odds ratio aOR = 1.60 [95% confidence interval 1.40-1.84]) and with less-qualified occupational categories (manual workers vs. managers and upper-intellectual positions: aOR = 2.96 [2.30-3.82]), even after adjusting for sociodemographic and other employment characteristics. Women with a pathological or at risk pregnancy left work earlier than other women. After stratification on type of pregnancy there was still a higher rate of early leave for women with less qualified occupational group. In France, social vulnerability of pregnant women, linked to low sociodemographic situation or low occupational categories, is associated with early leave during pregnancy, even after stratification on type of pregnancy. © The Author 2016.

    1978-08-01

    To identify the times of emergence of the permanent teeth of Canadian Eskimos (Inuit), 368 children and adolescents were examined. The presence or absence of all permanent teeth except the third molars was recorded and these data subjected to probit analysis. Female emergence times were advanced over males. Generally, the Inuit of both sexes showed statistically significant earlier emergence times than Montreal children, except for the incisors. The present results do not support hypotheses indicating that premature extraction of the deciduous teeth advances the emergence of their succedaneous counterparts. There is some indication the controls of deciduous tooth emergence continue to play some part in emergence of the permanent dentition, especially the first permanent teeth that emerge.

    2012-07-01

    Full Text Available The effect of copper stress on betacyanin accumulation and guaiacol peroxidase (GPOD activity in leaves of different age was evaluated in red beet (Beta vulgaris L. var. Crosby Egyptian plants. In hydroponic culture, plants were treated with 0.3 μM (control, 50 μM, 100 μM, and 250 μM of CuSO4 for 6 days. Copper was taken up and accumulated in old roots but was not translocated to leaves. However in young leaves, the increase of lipid peroxidation and reduction of growth were evident from day 3 of copper exposure; whereas in old leaves, the lipid peroxidation and growth were the same from either copper-treated or control plants. In response to copper exposure, the betacyanin accumulation was evident in young leaves by day 3, and continued to increase until day 6. Betacyanin only were accumulated in old leaves until day 6, but the contents were from 4 to 5 times lower than those observed in young leaves at the same copper concentrations. GPOD activity increased 3.3- and 1.4-fold in young and old leaves from day 3 of copper treatment respectively, but only in the young leaves was sustained at the same level until day 6. Old roots shown betacyanin in the control plants, but the betacyanin level and growth were reduced with the copper exposure. In contrast, young roots emerged by copper effect also accumulated copper and showed the highest betacyanin content of all plant parts assayed. These results indicate that betacyanin accumulation and GPOD activity are defense responses to copper stress in actively growing organs.

    Earlier this year we visited Sanya, Hainan Province, China. There is a huge statue, the South Sea Avalokitesvara (南海观世音菩萨), at Sanya Nanshan Buddhism Cultural Tourism Resort. When we were gazing at the statue on a leaving car on gradually rising road, an unexpected visual illusion took place in which the statue seemed running after us. In this presentation, an optical model is developed to explain the illusion occurred on a moving object leaving in fact but approaching by environmental judgement. Such an interesting illusion analysis will play a significant role in having students understood the main principles in geometrical optics.

    2001-09-01

    This research investigated the relationship between the length of women's maternity leave and marital incompatibility, in the context of other variables including the woman's employment, her dissatisfaction with the division of household labor, and her sense of role overload. Length of leave, work hours, and family salience were associated with several forms of dissatisfaction, which in turn predicted role overload. Role overload predicted increased marital incompatibility for experienced mothers but did not for first-time mothers, for whom discrepancies between preferred and actual child care were more important. Length of maternity leave showed significant interactions with other variables, supporting the hypothesis that a short leave is a risk factor that, when combined with another risk factor, contributes to personal and marital distress.

    Emergence refers to the unique human ability to aggregate information from seemingly meaningless pieces, and to perceive a whole that is meaningful. This special skill of humans can constitute an effective scheme to tell humans and machines apart. This paper presents a synthesis technique to generate images of 3D objects that are detectable by humans, but difficult for an automatic algorithm to recognize. The technique allows generating an infinite number of images with emerging figures. Our algorithm is designed so that locally the synthesized images divulge little useful information or cues to assist any segmentation or recognition procedure. Therefore, as we demonstrate, computer vision algorithms are incapable of effectively processing such images. However, when a human observer is presented with an emergence image, synthesized using an object she is familiar with, the figure emerges when observed as a whole. We can control the difficulty level of perceiving the emergence effect through a limited set of parameters. A procedure that synthesizes emergence images can be an effective tool for exploring and understanding the factors affecting computer vision techniques. © 2009 ACM.

  2. Anorectal emergencies

    2016-01-01

    Anorectal emergencies refer to anorectal disorders presenting with some alarming symptoms such as acute anal pain and bleeding which might require an immediate management. This article deals with the diagnosis and management of common anorectal emergencies such as acutely thrombosed external hemorrhoid, thrombosed or strangulated internal hemorrhoid, bleeding hemorrhoid, bleeding anorectal varices, anal fissure, irreducible or strangulated rectal prolapse, anorectal abscess, perineal necrotizing fasciitis (Fournier gangrene), retained anorectal foreign bodies and obstructing rectal cancer. Sexually transmitted diseases as anorectal non-surgical emergencies and some anorectal emergencies in neonates are also discussed. The last part of this review dedicates to the management of early complications following common anorectal procedures that may present as an emergency including acute urinary retention, bleeding, fecal impaction and anorectal sepsis. Although many of anorectal disorders presenting in an emergency setting are not life-threatening and may be successfully treated in an outpatient clinic, an accurate diagnosis and proper management remains a challenging problem for clinicians. A detailed history taking and a careful physical examination, including digital rectal examination and anoscopy, is essential for correct diagnosis and plan of treatment. In some cases, some imaging examinations, such as endoanal ultrasonography and computerized tomography scan of whole abdomen, are required. If in doubt, the attending physicians should not hesitate to consult an expert e.g., colorectal surgeon about the diagnosis, proper management and appropriate follow-up. PMID:27468181

  3. Do emotional support and classroom organization earlier in the year set the stage for higher quality instruction?

    2013-10-01

    Many teachers believe that providing greater emotional and organizational supports in the beginning of the year strengthens their ability to teach effectively as the year progresses. Some interventions, such as the Responsive Classroom (RC) approach, explicitly embed this sequence into professional development efforts. We tested the hypothesis that earlier emotional and organizational supports set the stage for improved instruction later in the year in a sample of third- and fourth-grade teachers enrolled in a randomized controlled trial of the RC approach. Further, we examined the extent to which the model generalized for teachers using varying levels of RC practices as well as whether or not teachers were in the intervention or control groups. Teachers' emotional, organizational, and instructional interactions were observed using the Classroom Assessment Scoring System (Pianta, La Paro, & Hamre, 2008) on five occasions throughout the year. Results indicated a reciprocal relation between emotional and instructional supports. Specifically, higher levels of emotional support earlier in the year predicted higher instructional support later in the year. Also, higher levels of instructional support earlier in the year predicted higher emotional support later in the year. Classroom organization was not found to have longitudinal associations with the other domains across a year. This pattern was robust when controlling for the use of RC practices as well as across intervention and control groups. Further, teachers' use of RC practices predicted higher emotional support and classroom organization throughout the year, suggesting the malleability of this teacher characteristic. Discussion highlights the connection between teachers' emotional and instructional supports and how the use of RC practices improves teachers' emotionally supportive interactions with students.

    2018-03-01

    Manufacturing particleboard (PB) made of leaves was carried out to make non-structural building components, such as insulation, partition, wall, and sheathing. Raw materials used dry leaves originated from plantation (palm oil leaves) and forest plantation (magahony leaves). The adhesive used was interior type thermosetting commercial resins, namely 10% urea-formaldehyde (UF) based on oven dry leaves. Hardener used for UF resin was 1% and 3% ammonium chloride (NH4Cl) 20% (w/w), respectively. Technically, the target density of PB was 0.8 g/cm3 with the dimension’s size of (250 x 250 x 10) mm3. The pressure, temperature, and time of pressing of the hot press were 25 kgf/cm2, 120C, and 10 minutes, respectively. After conditioning for one week, the PB then was evaluated their physical and mechanical properties according to Japanese Industrial Standard (JIS) A 5908 (2003). Results of this work showed: 1) Both types of PB (palm oil and mahagony leaves) were feasible to be produced for non-structural applications; 2) Addition of hardener enhanced the physical and mechanical properties of PB; 3) It was recommended to enhance the performance of the PB by manipulation of the raw materials and the design.

    Bodin Danielsson, Christina; Chungkham, Holendro Singh; Wulff, Cornelia; Westerlund, Hugo

    2014-01-01

    The effect of office type on sickness absence among office employees was studied prospectively in 1852 employees working in (1) cell-offices; (2) shared-room offices; (3) small, (4) medium-sized and (5) large open-plan offices; (6) flex-offices and (7) combi-offices. Sick leaves were self-reported two years later as number of (a) short and (b) long (medically certified) sick leave spells as well as (c) total number of sick leave days. Multivariate logistic regression analysis was used, with adjustment for background factors. A significant excess risk for sickness absence was found only in terms of short sick leave spells in the three open-plan offices. In the gender separate analysis, this remained for women, whereas men had a significantly increased risk in flex-offices. For long sick leave spells, a significantly higher risk was found among women in large open-plan offices and for total number of sick days among men in flex-offices. A prospective study of the office environment's effect on employees is motivated by the high rates of sick leaves in the workforce. The results indicate differences between office types, depending on the number of people sharing workspace and the opportunity to exert personal control as influenced by the features that define the office types.

  11. THE PERSONAS BEING (BAKHTIN’S CONCEPT OF THE HUMAN PERSONAS PRESENTED IN HIS EARLIER PHILOSOPHICAL WORKS OF THE 1920S

    Directory of Open Access Journals (Sweden)

    J. KOLESNICHENKO

    2011-08-01

    Full Text Available The author attempts a detailed analysis of the earlier philosophical works of Bakhtin which in themselves are somewhat open to question and often full of contradictions. Her aim is to try to determine an all-comprehensive key term which formed the core of the philosopher’s early thought. By means of various methods of analysis, the author concludes that this key term is «personality» («lichnost». For Bakhtin, Personalityhas not only a social dimension but contains a broader scope: it refl ects Being (the substantiality per se. It is the contention of the author that Bakhtin’s early studies should be read against the background of this central key-term of «lichnost». As a result, a new non-contradictory theory of personality emerges. The author emphasizes that Bakhtin’s theory of personality is one example of a new, avant-garde type of philosophical paradigm which arose during the 1920’s.

  12. Earlier (late Pliocene) first appearance of the Caribbean reef-building coral Acropora palmata: Stratigraphic and evolutionary implications

    Science.gov (United States)

    McNeill, Donald F.; Budd, Ann F.; Borne, Pamela F.

    1997-10-01

    An integrated stratigraphic study of reefal deposits on the Caribbean side of the Isthmus of Panama (Limon, Costa Rica) has discovered a significantly earlier first appearance of the major reef-building coral Acropora palmata. A. palmata is here reported from the early late Pliocene, constrained in age to within the Gauss chron (ca. 3.6 2.6 Ma). This coral was previously thought to have originated in the earliest Pleistocene and has subsequently been used as a Quaternary marker throughout the Caribbean and the Bahamas. An earlier appearance in the southern Caribbean implies a diachronous first appearance datum relative to the northern Caribbean. This older age also places A. palmata well within the transition phase of a Pliocene (4 1 Ma) faunal turnover that was marked by widespread extinction and origination of Caribbean coral species. An early late Pliocene origination is coincident with formation of the Isthmus, climate reorganization, and frequent sea-level changes associated with onset of Northern Hemisphere glaciations. The rapid growth and accumulation rates that characterize A. palmata may therefore be adaptive to these fluctuating environmental conditions, enabling its success during the subsequent Pleistocene glacial cycles.

    2016-11-01

    Full Text Available Cell-to-cell spread of HIV, a directed mode of viral transmission, has been observed to be more rapid than cell-free infection. However, a mechanism for earlier onset of viral gene expression in cell-to-cell spread was previously uncharacterized. Here we used time-lapse microscopy combined with automated image analysis to quantify the timing of the onset of HIV gene expression in a fluorescent reporter cell line, as well as single cell staining for infection over time in primary cells. We compared cell-to-cell spread of HIV to cell-free infection, and limited both types of transmission to a two-hour window to minimize differences due to virus transit time to the cell. The mean time to detectable onset of viral gene expression in cell-to-cell spread was accelerated by 19% in the reporter cell line and by 35% in peripheral blood mononuclear cells relative to cell-free HIV infection. Neither factors secreted by infected cells, nor contact with infected cells in the absence of transmission, detectably changed onset. We recapitulated the earlier onset by infecting with multiple cell-free viruses per cell. Surprisingly, the acceleration in onset of viral gene expression was not explained by cooperativity between infecting virions. Instead, more rapid onset was consistent with a model where the fastest expressing virus out of the infecting virus pool sets the time for infection independently of the other co-infecting viruses.

    Full Text Available In recent years, the surprising progress made in other areas of hematology (advances in the understanding of leukemogenesis, improved transplant techniques has been conspicuously absent in the management of hematologic emergencies. And yet, every step toward greater knowledge, every new treatment option will be of little value unless we are able to manage the acute complications of hematologic diseases. These complications are better defined as hematologic emergencies, and they are characterized by a high rate of mortality. This review is based on a search of the literature that was initially confined to articles published in the journal Hematology from 2000 to 2009. The search was then extended to the Cochrane Library and to Pub Med in February 2010 with the following Keywords emergencies; urgencies; hematology. The same key words were employed in a search of the archives of Blood and the New England Journal of Medicine from 2000 to 2010. The results confirm that hematologic emergencies can be caused by hematologic malignancies as well as by non-neoplastic hematologic diseases. Within the former category; this review examines the causes; manifestations; treatment and prevention of disseminated intravascular coagulation; superior vena caval syndrome; spinal cord compression; tumor lysis syndrome; hyperleukocytosis; and hypercalcemia. We also review emergency situations associated with non-neoplatic haematological diseases; such as thrombotic thrombocytopenic purpura; drug-induced hemolytic anemia; and acute sickle-cell crisis.

    Only 1 of 3 Austrian fathers involves himself daily in child rearing, and the younger the children, the less likely he is to be involved. Austria is among those European countries with the greatest pregnancy benefits. New mothers may take up to 1 year of paid maternity leave without fear of losing their jobs. This article uses 1982 Institute of Demography survey data to determine support for similar paternity leave for fathers. In the last few years, both Social Democrat and Conservative women have worked for this leave, although the movement has also found opposition by women in trade unions, as well as from conservative groups. Survey results show that 46% of married Austrian women, under age 40, favor paternity leave; 1 or 4 women can imagine their husbands taking such leave. Among husbands, 34% favored the leave option, and 1 of 4 could imagine taking the leave for a least part of the baby's first year. The study attempts to identify those husbands most likely to take advantage of paternity leave. At present, most men will not choose to stay with their children at the expense of earnings reduction. Compensation reforms for both mothers and fathers must first occur before men and women in a position to make real decisions on maternity and paternity leave.

    On September 19th 2008, a technical fault was at the centre of a sequence of events which hampered the performance of certain equipments of the LHC 3-4 sector. Once the first effects of this sequence of events were detected, the behaviour of the CERN staff confronted to this complex and critical situation became the centre of the risk control process. During such a downward spiral the preparation of all stakeholders is essential and should respect the (apparently) basic principles of emergency preparedness. Preparedness towards normal operation of CERN facilities towards minor up to major emergency situations will be presented. The main technical, organisational and legal frameworks of the CERN emergency preparedness will be recalled, highlighting the CERN risk management and risk control strategy. Then, the sequence of events experienced by different stakeholders on September 19th will be reported, thus starting the learned lessons process.

    The nuclear activities are exercised so as to prevent the accidents. They are subjected to a rule whom application is controlled by the Asn. The risk of grave accident is so limited to a very low level of probability. He cannot be however completely pushed aside. The expression ' radiological emergency situation ' indicates a situation which ensues from an incident or of an accident risking to lead to an emission of radioactive materials or a level of radioactivity susceptible to strike a blow at the public health. The term ' nuclear crisis ' is used for the events which can lead to a radiological emergency situation on a nuclear basic installation or during a transport of radioactive materials. The preparation and the management of emergency situations, that they are of natural, accidental or terrorist origin, became a major concern of our society. We propose you of to know more about it in this file. (N.C.)

    The book is directed at emergency radiologists and neuroradiologists. It aims at providing exhaustive information that will help the reader understand the clinical problems in the full range of neurological emergencies and to select the methodological and technical options that will ensure prompt and effective response and correct interpretation of the clinical findings. The various chapters address the most common neuroradiological emergencies, summarize their fundamental physiopathological features, describe the main semiological and differential diagnostic features, and provide operative suggestions for the selection of the appropriate techniques to be applied in a sequential order. The book addresses the application of state-of-the-art techniques and their implications for clinical practice (particularly the contributions of standard and functional MRI and of spiral and multislice CT). The illustrations provide not only training but also reference material for routine clinical work. (orig.)

    Full Text Available Emergency contraception refers to any device or drug that is used as an emergency procedure to prevent pregnancy after unprotected sexual intercourse.The first method of emergency contraception was high dose of estrogen. Concern about side effects led to subsequent development of the so-called Yuzpe regimen which combined ethinil estradiol with levonorgestrel and levonorgestrel alone. Less convenient to use is the copper intauterine contraceptive device.It is known that in some women sexual steroids may inhibit or delay ovulation and may interfere with ovum and sperm transport and implantation. Copper intrauterine device causes a foreign-body effect on the endometrium and a direct toxic effect to sperm and blastocyst.The Yuzpe regimen reduces the risk of pregnancy after a single act of sexual intercourse by about 75% and the levonorgestrel alone by about 85%. The copper intrauterine device is an extremely effective method for selected patients.Nausea and vomiting are common among women using the Yuzpe regimen and considerably less common among women using levonorgestrel alone regimen.Emergency contraception is relatively safe with no contraindications except pregnancy. It is ineffective if a woman is pregnant. There is no need for a medical hystory or a phisical examination before providing emergency contraceptive pills. They are taken long before organogenesis starts, so they should not have a teratogenic effect.Counseling should include information about correct use of the method, possible side effects and her preferences for regular contraception.Unintended pregnancy is a great problem. Several safe, effective and inexpensive methods of emergency contraception are available including Yuzpe regimen, levonorges-trel-only regimen and copper intrauterine device.

    Some of the most pronounced ecological responses to climatic warming are expected to occur in polar marine regions, where temperature increases have been the greatest and sea ice provides a sensitive mechanism by which climatic conditions affect sympagic (i.e., with ice) species. Population-level effects of climatic change, however, remain difficult to quantify. We used a flexible extension of Cormack-Jolly-Seber capture-recapture models to estimate population size and survival for polar bears (Ursus maritimus), one of the most ice-dependent of Arctic marine mammals. We analyzed data for polar bears captured from 1984 to 2004 along the western coast of Hudson Bay and in the community of Churchill, Manitoba, Canada. The Western Hudson Bay polar bear population declined from 1,194 (95% CI = 1,020-1,368) in 1987 to 935 (95% CI = 794-1,076) in 2004. Total apparent survival of prime-adult polar bears (5-19 yr) was stable for females (0.93; 95% CI = 0.91-0.94) and males (0.90; 95% CI = 0.88-0.91). Survival of juvenile, subadult, and senescent-adult polar bears was correlated with spring sea ice breakup date, which was variable among years and occurred approximately 3 weeks earlier in 2004 than in 1984. We propose that this correlation provides evidence for a causal association between earlier sea ice breakup (due to climatic warming) and decreased polar bear survival. It may also explain why Churchill, like other communities along the western coast of Hudson Bay, has experienced an increase in human-polar bear interactions in recent years. Earlier sea ice breakup may have resulted in a larger number of nutritionally stressed polar bears, which are encroaching on human habitations in search of supplemental food. Because western Hudson Bay is near the southern limit of the species' range, our findings may foreshadow the demographic responses and management challenges that more northerly polar bear populations will experience if climatic warming in the Arctic continues as

  5. Insights of the periodic reviews regarding the physical protection of nuclear power plants designed to earlier standards

    2001-01-01

    Among other prerequisites for licensing a nuclear activity, the German Atomic Energy Act stipulates that the necessary physical protection against malevolent acts has to be approved before granting a license. This is required for nuclear power plants in paragraph 7 of the Atomic Energy Act. The licenses for nuclear power plants designed to earlier standards were granted about 20 years ago and more. All NPPs are under the supervision of the Supervisory Authority in order to ensure that all conditions of the license are met during the whole plant operation period. The 'Periodic Safety Review', PSR, is designated to provide the Supervisory Authority with additional information on the safety status. One part of the PSR is the 'Deterministic Security Analysis', DSA. The subject of the DSA is the actual physical protection of a NPP. The following document outlines the experiences gained during the evaluation of DSA reports by GRS as an external expert organisation under contract of the Supervisory Authorities. (author)

    Mammographic screening is impractical in most of the world where breast cancers are first identified based on clinical signs and symptoms. Clinical breast examination may improve early diagnosis directly by finding breast cancers at earlier stages or indirectly by heightening women's awareness of breast health concerns. To investigate factors that influence time to presentation and stage at diagnosis among patients with breast cancer to determine whether history of previous clinical breast examination is associated with earlier presentation and/or earlier cancer stage at diagnosis. In this cross-sectional analysis of individual patient interviews using a validated Breast Cancer Delay Questionnaire, 113 (71.1%) of 159 women with breast cancer treated at a federally funded tertiary care referral cancer center in Trujillo, Peru, from February 1 through May 31, 2015, were studied. Method of breast cancer detection and factors that influence time to and stage at diagnosis. Of 113 women with diagnosed cancer (mean [SD] age, 54 [10.8] years; age range, 32-82 years), 105 (92.9%) had self-detected disease. Of the 93 women for whom stage was documented, 45 (48.4%) were diagnosed with early-stage disease (American Joint Committee on Cancer [AJCC] stage 0, I, or II), and 48 (51.6%) were diagnosed with late-stage disease (AJCC stage III or IV). Mean (SD) total delay from symptom onset to initiation of treatment was 407 (665) days because of patient (mean [SD], 198 [449] days) and health care system (mean [SD], 241 [556] days) delay. Fifty-two women (46.0%) had a history of clinical breast examination, and 23 (20.4%) had undergone previous mammography. Women who underwent a previous clinical breast examination were more likely to have shorter delays from symptom development to presentation compared with women who had never undergone a previous clinical breast examination (odds ratio, 2.92; 95% CI, 1.30-6.60; P = .01). Women diagnosed with shorter patient delay were more

  7. Low protein content of drainage fluid is a good predictor for earlier chest tube removal after lobectomy.

    Owing to the great absorption capability of the pleura for transudates, the protein content of draining pleural fluid may be considered as a more adequate determinant than its daily draining amount in the decision-making for earlier chest tube removal. In an a priori pilot study, we observed that the initially draining protein-rich exudate converts to a transudate quickly in most patients after lobectomies. Thus, chest tubes draining high-volume but low-protein fluids can safely be removed earlier in the absence of an air leak. This randomized study aims to investigate the validity and clinical applicability of this hypothesis as well as its influence on the timing for chest tube removal and earlier discharge after lobectomy. Seventy-two consecutive patients undergoing straightforward lobectomy were randomized into two groups. Patients with conditions affecting postoperative drainage and with persisting air leaks beyond the third postoperative day were excluded. Drains were removed if the pleural fluid to blood protein ratio (PrRPl/B) was ≤0.5, regardless of its daily draining amount in the study arm (Group S; n = 38), and patients in the control arm (Group C; n = 34) had their tubes removed if daily drainage was ≤250 ml regardless of its protein content. Patients were discharged home immediately or the following morning after removal of the last drain. All cases were followed up regarding the development of symptomatic pleural effusions and hospital readmissions for a redrainage procedure. Demographic and clinical characteristics as well as the pattern of decrease in PrRPl/B were the same between groups. The mean PrRPl/B was 0.65 and 0.67 (95% CI = 0.60-0.69 and 0.62-0.72) on the first postoperative day, and it remarkably dropped down to 0.39 and 0.33 (95% CI = 0.33-0.45 and 0.27-0.39) on the second day in Groups S and C, respectively, and remained below 0.5 on the third day (repeated-measures of ANOVA design, post hoc 'within-group' comparison of the first

  8. Complementary functions of the two brain hemispheres: comparisons with earlier conceptions and implications for individual and society.

    The concept of different functions for the left and right cerebral hemispheres coincides in an astonishing way with earlier philosophical and psychological work which divided the human mind into two complementary functions without having a neurophysiological explanation. Representative are the ideas of Fichte, Hegel and Jung. The latter postulated the two subsystems Ego and Self and associated the conscious functions of the Ego with the intellect, the capacity for rational thought, and the Self with the mind, which also includes the emotional feelings. For the harmonic development and self-realization of man the functions of both systems in complementary interaction are required. Therefore, the current overaccentuation of the intellect and of progress directed technical-scientific thinking should be corrected by making better use of the much neglected functions of the right hemisphere.

  16. Earlier visual N1 latencies in expert video-game players: a temporal basis of enhanced visuospatial performance?

    Full Text Available Increasing behavioural evidence suggests that expert video game players (VGPs show enhanced visual attention and visuospatial abilities, but what underlies these enhancements remains unclear. We administered the Poffenberger paradigm with concurrent electroencephalogram (EEG recording to assess occipital N1 latencies and interhemispheric transfer time (IHTT in expert VGPs. Participants comprised 15 right-handed male expert VGPs and 16 non-VGP controls matched for age, handedness, IQ and years of education. Expert VGPs began playing before age 10, had a minimum 8 years experience, and maintained playtime of at least 20 hours per week over the last 6 months. Non-VGPs had little-to-no game play experience (maximum 1.5 years. Participants responded to checkerboard stimuli presented to the left and right visual fields while 128-channel EEG was recorded. Expert VGPs responded significantly more quickly than non-VGPs. Expert VGPs also had significantly earlier occipital N1s in direct visual pathways (the hemisphere contralateral to the visual field in which the stimulus was presented. IHTT was calculated by comparing the latencies of occipital N1 components between hemispheres. No significant between-group differences in electrophysiological estimates of IHTT were found. Shorter N1 latencies may enable expert VGPs to discriminate attended visual stimuli significantly earlier than non-VGPs and contribute to faster responding in visual tasks. As successful video-game play requires precise, time pressured, bimanual motor movements in response to complex visual stimuli, which in this sample began during early childhood, these differences may reflect the experience and training involved during the development of video-game expertise, but training studies are needed to test this prediction.

    Our goal was to determine whether adverse childhood experiences predicted the age at which drinking was initiated and drinking motives in a representative sample of current or former drinkers in the United States. In 2006, a probability sample of 3592 US current or former drinkers aged 18 to 39 were surveyed. Multinomial logistic regression examined whether each of 10 adverse childhood experiences was associated with earlier ages of drinking onset, controlling for demographics, parental alcohol use, parental attitudes toward drinking, and peers' drinking in adolescence. We also examined whether there was a graded relationship between the number of adverse childhood experiences and age of drinking onset and whether adverse childhood experiences were related to self-reported motives for drinking during the first year that respondents drank. Sixty-six percent of respondents reported >or=1 adverse childhood experiences, and 19% reported experiencing >or=4. The most commonly reported adverse childhood experiences were parental separation/divorce (41.3%), living with a household member who was a problem drinker (28.7%), mental illness of a household member (24.8%), and sexual abuse (19.1%). Of the 10 specific adverse childhood experiences assessed, 5 were significantly associated with initiating drinking at or=21 years of age) after adjustment for confounders, including physical abuse, sexual abuse, having a mentally ill household member, substance abuse in the home, and parental discord or divorce. Compared with those without adverse childhood experiences, respondents with adverse childhood experiences were substantially more likely to report that they drank to cope during the first year that they used alcohol. Results suggest that children with particular adverse childhood experiences may initiate drinking earlier than their peers and that they may be more likely to drink to cope with problems (rather than for pleasure or to be social).

    Remote monitoring (RM) has been advocated as the new standard of care for patients with cardiovascular implantable electronic devices (CIEDs). RM has allowed the early detection of adverse clinical events, such as arrhythmia, lead failure, and battery depletion. However, lead failure was often identified only by arrhythmic events, but not impedance abnormalities. To compare the usefulness of arrhythmic events with conventional impedance abnormalities for identifying lead failure in CIED patients followed by RM. CIED patients in 12 hospitals have been followed by the RM center in Okayama University Hospital. All transmitted data have been analyzed and summarized. From April 2009 to March 2016, 1,873 patients have been followed by the RM center. During the mean follow-up period of 775 days, 42 lead failure events (atrial lead 22, right ventricular pacemaker lead 5, implantable cardioverter defibrillator [ICD] lead 15) were detected. The proportion of lead failures detected only by arrhythmic events, which were not detected by conventional impedance abnormalities, was significantly higher than that detected by impedance abnormalities (arrhythmic event 76.2%, 95% CI: 60.5-87.9%; impedance abnormalities 23.8%, 95% CI: 12.1-39.5%). Twenty-seven events (64.7%) were detected without any alert. Of 15 patients with ICD lead failure, none has experienced inappropriate therapy. RM can detect lead failure earlier, before clinical adverse events. However, CIEDs often diagnose lead failure as just arrhythmic events without any warning. Thus, to detect lead failure earlier, careful human analysis of arrhythmic events is useful. © 2017 Wiley Periodicals, Inc.

    Spectropolarimetry of intact plant leaves allows to probe the molecular architecture of vegetation photosynthesis in a non-invasive and non-destructive way and, as such, can offer a wealth of physiological information. In addition to the molecular signals due to the photosynthetic machinery, the cell structure and its arrangement within a leaf can create and modify polarization signals. Using Mueller matrix polarimetry with rotating retarder modulation, we have visualized spatial variations in polarization in transmission around the chlorophyll a absorbance band from 650 nm to 710 nm. We show linear and circular polarization measurements of maple leaves and cultivated maize leaves and discuss the corresponding Mueller matrices and the Mueller matrix decompositions, which show distinct features in diattenuation, polarizance, retardance and depolarization. Importantly, while normal leaf tissue shows a typical split signal with both a negative and a positive peak in the induced fractional circular polarization and circular dichroism, the signals close to the veins only display a negative band. The results are similar to the negative band as reported earlier for single macrodomains. We discuss the possible role of the chloroplast orientation around the veins as a cause of this phenomenon. Systematic artefacts are ruled out as three independent measurements by different instruments gave similar results. These results provide better insight into circular polarization measurements on whole leaves and options for vegetation remote sensing using circular polarization. Copyright © 2018 The Author(s).

    1996-01-01

    In 1995, major efforts of the Nuclear Regulatory Authority of the Slovak Republic (NRA SR) were focused on tasks associated with completion and incorporation of the Emergency Response Centre (ERC) of NRA SR in emergency planning and crisis management. Construction of the ERC had begun based on NRA SR's knowledge, as well as recommendations of Regulatory Assistance Management Group (RAMG) International Mission in 1993 and follow-up missions in 1994. Early in 1994, re-construction of selected rooms had been done and early in 1995, supported by the UK and U.S.A. Government's funding, technical equipment was purchased. The equipment was necessary for ERC operation as tools to improve NRA SR readiness for the management of emergency situations at nuclear installations. NRA SR commenced operation of the Centre in April 1995. The Centre has been on-line connected to a teledosimetric system of Radiation Monitoring Laboratory in Trnava. The basic software for assessment of radiation consequences of a NPP accident was supplied were also focused on cooperation with state administration authorities and organizations which were involved in an emergency planning structure. In September 1995, staffing of the ERC was completed and parallel, the first document concerning the ERC prime task, i.e. activities and procedures of of NRA SR Crisis crew in case of an accident at a nuclear installation on the territory of the Slovak Republic, was approved by the NRA SR's Management. In the period that is being assessed, NRA SR made significant progress in events classification and emergency planning terminology in order to unify the above between both the Slovak NPPs

  6. The dewetting properties of lotus leaves.

    Science.gov (United States)

    Zhang, Jihua; Sheng, Xianliang; Jiang, Lei

    2009-02-03

    The high dewetting abilities of lotus leaves can be transited to a complete wetting state by soaking the leaves in water at a depth of 50 cm for 2 h. However, after being dried by N2 gas, the high dewetting behavior of lotus leaves may be mostly restored. This indicates that experimental procedure might considerably affect the dewetting abilities of lotus leaves. To discover the mechanism underlying this interesting dewetting phenomena, the dewetting force was used to characterize the dewetting abilities of surfaces, and model studies to mimic the papillae were done. Surface hydrophobicity, sizes, rise angles, and secondary structures of the models' sides affected their dewetting force with water. So we suggested that the dewetting states, Cassie or Wenzel's state, of lotus surfaces depend much on the depth of water, i.e., the hydraulic pressure. On the other hand, the primary structures of papillae in Cassie's state led to a high receding angle with respect to the plane of the leaf during the dewetting measurement. The secondary structures and micro/nano arrays of papillae increased the dewetting abilities of lotus leaves, since no water intruded between papillae. However, the structures of papillae in Wenzle's state significantly reduced the dewetting abilities of lotus leaves after being soaked at a depth of 50 cm for 2 h. Therefore, as for novel designs of microdevices floating on water, including the use of the high dewetting properties of suphydrophobic materials, surface (primary or secondary) microstructure and external pressure, such as static hydraulic pressure, must be taken into account.

    We study the short, medium, and longer run employment effects of a substantial change in the parental leave benefit program in Germany. In 2007, a means-tested parental leave transfer program that had paid benefits for up to two years was replaced by an earnings related transfer which paid benefits for up to one year. The reform generated winners and losers with heterogeneous response incentives. We find that the reform speeds up the labor market return of both groups of mothers after benefit...

    Female labour force participation is high in Norway but sickness absence rates are higher for women than for men. This may be partly a result of unequal sharing of childcare in the family. In this paper, we consider the effect of paternity leave on sickness absence among women who have recently given birth. We draw on a six-year panel taken from full population data from administrative sources. We find that in the 6% of families where fathers take out leave more than the standard quota (gende...

  14. Emerging Jets

    CERN Document Server

    Schwaller, Pedro; Weiler, Andreas

    2015-01-01

    In this work, we propose a novel search strategy for new physics at the LHC that utilizes calorimeter jets that (i) are composed dominantly of displaced tracks and (ii) have many different vertices within the jet cone. Such emerging jet signatures are smoking guns for models with a composite dark sector where a parton shower in the dark sector is followed by displaced decays of dark pions back to SM jets. No current LHC searches are sensitive to this type of phenomenology. We perform a detailed simulation for a benchmark signal with two regular and two emerging jets, and present and implement strategies to suppress QCD backgrounds by up to six orders of magnitude. At the 14 TeV LHC, this signature can be probed with mediator masses as large as 1.5 TeV for a range of dark pion lifetimes, and the reach is increased further at the high-luminosity LHC. The emerging jet search is also sensitive to a broad class of long-lived phenomena, and we show this for a supersymmetric model with R-parity violation. Possibilit...

The new room enable the work for radiation protection group, reactor safety and logistic group separately. At the same time special room was build for work of the NECRA Technical Support Group of the Emergency Commission for Radiation Accidents of the SR.This group co-operates closely with ERC while evaluation the situation, and by using the information system of the NRA and database of ERC to generate the conditions of nuclear facilities in once of emergency. Extension of the mentioned rooms was carried out. The financing by the European Union helped to build the project RAMG. In this way the NRA gained a working site which, with its equipment and parameters belongs to the top working sites of regulatory bodies of developed European countries. The NRA preparation of exercise and special staff education was carried out in 1997, for employees of the NRA and members of Emergency Headquarters (EH) for work in ERC in case of nuclear installation accident. The task of education of member of EH was their preparation for carrying out three exercises. These exercises are described. In the area of emergency preparedness, in accordance with inspection plan of the Office, 7 team inspections were carried out in individual localities; in NPP Bohunice, two in NPP Mochovce and one in Bohunice Conditioning Centre for radioactive wastes. Solution of the task of development of science and technology in the area of 'Development of technical and programme means for analyses of accidents and solutions of crisis situations'continued in 1997. Another regulations were elaborated for activity of members of EH of the NRA. The following was was carried out: selection of data for transfer and the

The aim of the investigation was to identify fungi causing the death of leaf tissues of herbs from the mint family Lamiaceae. In mycological investigations, 180 fragments of each plant leaves (1,080 dead leaf fragments in total were placed in a 2% PDA medium. Over 970 colonies of fungi belonging to 48 species were isolated from the dead leaf tissues of the six herb species. Alternaria alternata (toxin-producing, Epicoccum nigrum and Sordaria fimicola were the most frequently isolated. The largest numbers of colonies and species of fungi were isolated from horsemint, while the lowest numbers were from wild marjoram leaves. It was shown that the death of leaves of selected herb species from the Lamiaceae family was caused by various fungi. The results of the mycological analysis confirmed the diversity of species colonizing the leaves of the herbs.

    Radioactive contamination of foodstuffs attributed to the Fukushima Daiichi nuclear disaster has become a social problem. This study investigated the extraction of radioactive cesium from the contaminated leaves to the tea. The green tea was brewed twice reusing the same leaves to study the difference in extraction of cesium between the first and second brew. Moreover, the extraction of cesium was studied in correlation to brewing time. The concentration of radioactive cesium was determined with gamma spectrometry, and the concentration of caffeine was determined with absorption spectrometry. About 40% of cesium was extracted from leaves in the first brew, and about 80% was extracted in the second brew. The extraction of cesium increased over time, and it reached about 80% after 10 minutes brew. The ratio of radioactive cesium to caffeine decreased linearly over time. This study revealed that the extraction of cesium was higher for the second brew, and a rapid increase in extraction was seen as the tea was brewed for 6 minutes and more. Therefore, the first brew of green tea, which was brewed within 5 minutes, contained the least extraction of radioactive cesium from the contaminated leaves. (author)

  16. Maternity leave duration and postpartum mental and physical health: implications for leave policies.

    Science.gov (United States)

    Dagher, Rada K; McGovern, Patricia M; Dowd, Bryan E

    2014-04-01

    This study examines the association of leave duration with depressive symptoms, mental health, physical health, and maternal symptoms in the first postpartum year, using a prospective cohort design. Eligible employed women, eighteen years or older, were interviewed in person at three Minnesota hospitals while hospitalized for childbirth in 2001. Telephone interviews were conducted at six weeks (N = 716), twelve weeks (N = 661), six months (N = 625), and twelve months (N = 575) after delivery. Depressive symptoms (Edinburgh Postnatal Depression Scale), mental and physical health (SF-12 Health Survey), and maternal childbirth-related symptoms were measured at each time period. Two-stage least squares analysis showed that the relationship between leave duration and postpartum depressive symptoms is U-shaped, with a minimum at six months. In the first postpartum year, an increase in leave duration is associated with a decrease in depressive symptoms until six months postpartum. Moreover, ordinary least squares analysis showed a marginally significant linear positive association between leave duration and physical health. Taking leave from work provides time for mothers to rest and recover from pregnancy and childbirth. Findings indicate that the current leave duration provided by the Family and Medical Leave Act, twelve weeks, may not be sufficient for mothers at risk for or experiencing postpartum depression.

    Parental leave is linked to health benefits for both child and parent. It is unclear whether surgeons at academic centers have access to paid parental leave. The aim of this study was to determine parental leave policies at the top academic medical centers in the United States to identify trends among institutions. The top academic medical centers were identified (US News & World Report 2016). Institutional websites were reviewed, or human resource departments were contacted to determine parental leave policies. "Paid leave" was defined as leave without the mandated use of personal time off. Institutions were categorized based on geographical region, funding, and ranking to determine trends regarding availability and duration of paid parental leave. Among the top 91 ranked medical schools, 48 (53%) offer paid parental leave. Availability of a paid leave policy differed based on private versus public institutions (70% versus 38%, P leaves (>6 wk) than public institutions (67% versus 33%; P = 0.02). No difference in paid leave duration was noted based on region (P = 0.60) or rank (P = 0.81). Approximately, 50% of top academic medical centers offer paid parental leave.

    Recent work with young adults has shown that, depending on study context access, selective memory retrieval can both impair and improve recall of other memories (Bäuml & Samenieh, 2010). Here, we investigated the 2 opposing effects of selective retrieval in older age. In Experiment 1, we examined 64 younger (20-35 years) and 64 older participants (above 60 years), and manipulated study context access using list-method directed forgetting. Whereas both age groups showed a detrimental effect of selective retrieval on to-be-remembered items, only younger but not older adults showed a beneficial effect on to-be-forgotten items. In Experiment 2, we examined 112 participants from a relatively wide age range (40-85 years), and manipulated study context access by varying the retention interval between study and test. Overall, a detrimental effect of selective retrieval arose when the retention interval was relatively short, but a beneficial effect when the retention interval was prolonged. Critically, the size of the beneficial but not the detrimental effect of retrieval decreased with age and this age-related decline was mediated by individuals' working memory capacity, as measured by the complex operation span task. Together, the results suggest an age-related dissociation in retrieval dynamics, indicating an earlier decline of the beneficial than the detrimental effect of selective retrieval with older age.

    Humans and other mammals mount vigorous immune assaults against helminth parasites, yet there are intriguing reports that the immune response can enhance rather than impair parasite development. It has been hypothesized that helminths, like many free-living organisms, should optimize their development and reproduction in response to cues predicting future life expectancy. However, immune-dependent development by helminth parasites has so far eluded such evolutionary explanation. By manipulating various arms of the immune response of experimental hosts, we show that filarial nematodes, the parasites responsible for debilitating diseases in humans like river blindness and elephantiasis, accelerate their development in response to the IL-5 driven eosinophilia they encounter when infecting a host. Consequently they produce microfilariae, their transmission stages, earlier and in greater numbers. Eosinophilia is a primary host determinant of filarial life expectancy, operating both at larval and at late adult stages in anatomically and temporally separate locations, and is implicated in vaccine-mediated protection. Filarial nematodes are therefore able to adjust their reproductive schedules in response to an environmental predictor of their probability of survival, as proposed by evolutionary theory, thereby mitigating the effects of the immune attack to which helminths are most susceptible. Enhancing protective immunity against filarial nematodes, for example through vaccination, may be less effective at reducing transmission than would be expected and may, at worst, lead to increased transmission and, hence, pathology.

    Among other prerequisites for licensing a nuclear activity, the German Atomic Energy Act stipulates that the necessary physical protection against malevolent acts has to be approved before granting a license. This is required for nuclear power plants in paragraph 7 of the Atomic Energy Act. The licenses for nuclear power plants designed to earlier standards were granted about 20 years ago and more. All NPPs are under the supervision of the Supervisory Authority in order to ensure that all conditions of the license are met during the whole plant operation period. The 'Periodic Safety Review', PSR, is designated to provide the Supervisory Authority with additional information on the safety status. One part of the PSR is the 'Deterministic Security Analysis', DSA. The subject of the DSA is the actual physical protection of a NPP. The following document outlines the experiences gained during the evaluation of DSA reports by GRS as an external expert organisation under contract of the Supervisory Authorities. (author)

    Older persons with earlier trauma are often more vulnerable to stresses of old age. To examine the levels of emotional distress in relation to cognitive appraisal of acute hospitalization and coping strategies in Holocaust survivors compared with an age- and education-matched group of elderly persons without Holocaust experience. This is a cross-sectional study of 63 Holocaust survivors, 65 years and older, hospitalized for an acute illness, and 57 age-, education- and hospital unit-matched people without Holocaust experience. Participants completed appraisal and coping strategies (COPE) questionnaires, and the brief symptoms inventory (BSI-18). Holocaust survivors reported higher levels of emotional distress, appraised the hospitalization higher as a threat and lower as a challenge, and used more emotion-focused and less problem-focused or support-seeking coping strategies than the comparison group. Study variables explained 65% of the variance of emotional distress; significant predictors of emotional distress in the final regression model were not having a partner and more use of emotion-focused coping. The latter mediated the relation of group variable and challenge appraisal to emotional distress. Health professionals must be aware of the potential impact of the hospital environment on the survivors of Holocaust as well as survivors of other trauma. Being sensitive to their specific needs may reduce the negative impact of hospitalization.

    The emerging care personnel shortage in Swiss nursing homes is aggravated by high turnover rates. As intention to leave is a predictor of turnover, awareness of its associated factors is essential. This study applied a secondary data analysis to evaluate the prevalence and variability of 3,984 nursing home care workers' intention to leave. Work environment factors and care worker outcomes were tested via multiple regression analysis. Although 56% of care workers reported intention to leave, prevalences varied widely between facilities. Overall, intention to leave showed strong inverse relationships with supportive leadership and affective organizational commitment and weaker positive relationships with stress due to workload, emotional exhaustion, and care worker health problems. The strong direct relationship of nursing home care workers' intention to leave with affective organizational commitment and perceptions of leadership quality suggest that multilevel interventions to improve these factors might reduce intention to leave.

    Full text: There are numerous conditions that affect mainly or exclusively the pediatric population. These constitute true emergencies, related to patient's health. Delay in diagnosis and treatment of abdominal non-traumatic emergencies may result in rapid deterioration, peritonitis, sepsis, even death or in severe complications with subsequent morbidity. Abdominal emergencies in children mostly present with pain, tenderness, occasionally coupled by vomiting, fever, abdominal distension, and failure to pass meconium or stools. Diarrhea, blood per rectum, abnormal laboratory tests and lethargy may also be manifestations of acute abdominal conditions. Abdominal emergencies have a different aetiology, depending on age and whether the pain is acute or chronic. Symptoms have to be matched with age and gender. Newborns up to 1 months of age may have congenital diseases: atresia, low obstruction including Hirschsprung's disease, meconium ileus. Meconium plug is one of the commonest cause of low obstruction in newborns that may also develop necrotizing enterocolitis, incarcerated inguinal hernia and mid-gut volvulus. Past the immediate postnatal period, any duodenal obstruction should be considered midgut volvulus until proven otherwise and patients should undergo ultrasonography and/or properly performed upper GI contrast study that records the exact position of the deduno-jejunal junction. Infants 6 months-2 years carry the risk of intussusception, mid-gut volvulus, perforation, acute pyelonephritis. Preschool and school-aged children 2-12 years carry the risk of appendicitis, genito-urinary abnormalities including torsion, urachal abnormalities, haemolytic uremic syndrome and Henoch-Schonlein purpura. Children above 12 years suffer from the same conditions as in adults. Most conditions may affect any age despite age predilection. Abdominal solid organ ultrasonography (US) coupled with gastrointestinal ultrasonography is the principle imaging modality in radiosensitive

    The Bologna process is to improve the quality of education, mobility, diversity and the competitiveness and involves three fundamental changes: transform of the structure of titles, changing in methods of teaching and implementation of the systems of quality assurance. Once that the new degrees have been implemented with this structure, and began at E.T.S. of Agriculture Engineering (ETSIA) at Madrid from 2010-2011 course, the main aim of this work is to deeply study the changes in teaching methodology as well as progressively implementation of the educational planning of the three new degrees: Engineering and Agronomic Graduate, Food Industry Engineering Graduate and Agro-environmental Graduate. Each one of them presents 240 ECTS with a common first course and will have access to an official Master in Agronomic Engineering. As part as an educational innovation project awarded by the Technical University of Madrid (UPM) to improve educational quality, the second course has been designed with the main objective to continue the educative model implemented last course. This model identifies several teaching activities and represents a proper teaching style at ETSIA-UPM. At the same time, a monitoring and development coordination plans have been established. On the other hand, a procedure to extinguish the earlier plans of Agriculture Engineering was also defined. Other activities related to this Project were the information improvement of the grades, in particular at High Schools centers, improving the processes of reception, counseling and tutoring and mentoring. Likewise, cooperative working workshops and programs to support the teaching of English language were implemented. Satisfaction surveys and opinion polls were done to professors and students involved in first course in order to test several aspects of this project. The students surveys were analyzed taking in account the academic results and their participation in mentoring activities giving a highly

  10. Women's Reasons for Leaving the Engineering Field.

    Among the different Science, Technology, Engineering, and Math fields, engineering continues to have one of the highest rates of attrition (Hewlett et al., 2008). The turnover rate for women engineers from engineering fields is even higher than for men (Frehill, 2010). Despite increased efforts from researchers, there are still large gaps in our understanding of the reasons that women leave engineering. This study aims to address this gap by examining the reasons why women leave engineering. Specifically, we analyze the reasons for departure given by national sample of 1,464 women engineers who left the profession after having worked in the engineering field. We applied a person-environment fit theoretical lens, in particular, the Theory of Work Adjustment (TWA) (Dawis and Lofquist, 1984) to understand and categorize the reasons for leaving the engineering field. According to the TWA, occupations have different "reinforcer patterns," reflected in six occupational values, and a mismatch between the reinforcers provided by the work environment and individuals' needs may trigger departure from the environment. Given the paucity of literature in this area, we posed research questions to explore the reinforcer pattern of values implicated in women's decisions to leave the engineering field. We used qualitative analyses to understand, categorize, and code the 1,863 statements that offered a glimpse into the myriad reasons that women offered in describing their decisions to leave the engineering profession. Our results revealed the top three sets of reasons underlying women's decision to leave the jobs and engineering field were related to: first, poor and/or inequitable compensation, poor working conditions, inflexible and demanding work environment that made work-family balance difficult; second, unmet achievement needs that reflected a dissatisfaction with effective utilization of their math and science skills, and third, unmet needs with regard to lack of recognition

    Japanese Tea Leaves, prepared by pulverizing with an agate ball mill and sieving with a Saran fiber sieve (50 mesh) were assessed as a possible biological standard reference material for elemental analysis. The metal content of the tea leaves was determined independently at two laboratories using atomic absorption and flame emission spectrometry. Neutron activation analysis was also performed to determine the content (21 elements) of Tea Leaves. For some elements the result from the various methods were compared. The characteristics of Tea Leaves are discussed and the elemental composition is compared to that of Orchard Leaves (NBS SRM, 1571). The most significant characteristic of Tea Leaves was the high manganese content. (auth.)

    “Don’t leave your baggage unattended” is a familiar request to anyone who travels by air, but it’s good advice wherever you may be.    At CERN, if an unattended bag is found anywhere on the site, the Fire and Rescue service will be called to evacuate the area, maintain a security perimeter for as long as necessary, and attempt to identify the owner. If the owner cannot be found in a reasonable amount of time, there’s a very strong chance that the bag will be destroyed. You can take two simple steps to avoid this fate: Don’t leave your baggage unattended;   Make sure that your contact details are clearly visible on the bag or suitcase so that, should you find yourself separated from it, you can easily be reunited.

    2016-02-01

    Superhydrophobic surfaces with the self-cleaning behavior of lotus leaves are sought for drag reduction and phase change heat transfer applications. These superrepellent surfaces have traditionally been fabricated by random or deterministic texturing of a hydrophobic material. Recently, superrepellent surfaces have also been made from hydrophilic materials, by deterministic texturing using photolithography, without low-surface energy coating. Here, we show that hydrophilic materials can also be made superrepellent to water by chemical texturing, a stochastic rather than deterministic process. These metallic surfaces are the first analog of lotus leaves, in terms of wettability, texture and repellency. A mechanistic model is also proposed to describe the influence of multiple tiers of roughness on wettability and repellency. This demonstrated ability to make hydrophilic materials superrepellent without deterministic structuring or additional coatings opens the way to large scale and robust manufacturing of superrepellent surfaces.Superhydrophobic surfaces with the self-cleaning behavior of lotus leaves are sought for drag reduction and phase change heat transfer applications.

    Full Text Available Objectives: Previous research on the association between adjustment latitude (defined as the opportunity to adjust work efforts in case of illness and sickness absence and sickness presence has produced inconsistent results. In particular, low adjustment latitude has been identified as both a risk factor and a deterrent of sick leave. The present study uses an alternative analytical strategy with the aim of joining these results together. Material and Methods: Using a cross-sectional design, a random sample of employees covered by the Upper Austrian Sickness Fund (N = 930 was analyzed. Logistic and ordinary least square (OLS regression models were used to examine the association between adjustment latitude and days of sickness absence, sickness presence, and an estimator for the individual sickness absence and sickness presence propensity. Results: A high level of adjustment latitude was found to be associated with a reduced number of days of sickness absence and sickness presence, but an elevated propensity for sickness absence. Conclusions: Employees with high adjustment latitude experience fewer days of health complaints associated with lower rates of sick leave and sickness presence compared to those with low adjustment latitude. In case of illness, however, high adjustment latitude is associated with a higher pro­bability of taking sick leave rather than sickness presence.

    Full Text Available The adult height of children with early onset puberty is limited by the premature maturation of hypothalamic-pituitary-gonadal axis. To evaluate the effects of gonadotropin-releasing hormone analog (GnRHa treatment on the final height (FH and bone maturation rate (BMR in girls with early puberty (EP or idiopathic central precocious puberty (ICPP, we examined data from girls who were diagnosed with EP or ICPP and underwent GnRHa (Leuplin Depot: 3.75 mg/month at China Medical University Hospital, in Taiwan, between 2006 and 2015. Patients were observed until the achievement of FH and divided into an "EP group" (T-ep and "ICPP group" (T-icpp according to the age of onset of puberty. Eighty-seven patients were enrolled (T-ep, N = 44, puberty onset at 8-10 years; T-icpp, N = 43, puberty onset before 8 years. The demographic data of girls with EP or IPP was characterized. BMR, change in predicted final height (PFH after GnRHa treatment, target height (TH and FH were measured. After GnRHa treatment, the study groups (T-ep: 160.24±6.18 cm, T-icpp: 158.99±5.92 cm both had higher PFH than at initiation (T-ep: 159.83±7.19 cm, T-icpp: 158.58±5.93 cm. There was deceleration of BMR in both groups (T-ep: 0.57±0.39; T-icpp: 0.97±0.97 and a significant difference between the groups (p = 0.027. The gap in FH standard deviation scores (SDS and TH SDS had a significant difference in T-ep (p = 0.045 but not in T-icpp. Moreover, there was no difference in the gap of PFH SDS between the 1st and final treatment in both groups. We concluded that GnRHa decelerated BMR in girls with earlier puberty. Further prospective clinical studies are warranted.

  18. How kinship systems and welfare regimes shape leaving home: A comparative study of the United States, Germany, Taiwan, and China

    Bernhard Nauck

    2017-04-01

    Full Text Available Objective: This paper aims to explain societal differences in the event of leaving the parental home as part of the transition to adulthood, in the United States, Germany, China, and Taiwan. It proposes bridge hypotheses between societal characteristics such as kinship system and welfare regime and home-leaving behavior, and tests them with nationally representative panel studies. Methods: Four panel studies (NLSY97 for the USA; PAIRFAM for Germany; CFPS for China; TYP for Taiwan were harmonized for similar cohorts, with an age span of 15 to 30 years. Testing was based on age-specific tabulations of household composition and separate discrete-time event history models. Results: The prevalence of home-leaving is highest in the United States, followed by Germany, China, and then Taiwan. Timing is earlier in the United States than in Germany, and earlier in China than in Taiwan. Gender-specific coincidence of home-leaving with entry into higher education, the work force, cohabitation, and marriage can be conclusively related to differences in kinship system and welfare regime, and regional opportunity disparities. Contribution: The empirical results point to significant cultural differences between home-leaving in collectivistic, patrilineal societies (China, Taiwan and individualistic, bilineal societies (USA, Germany. Whereas neolocal housing signifies an important step in the transition to adulthood in the latter societies, continuous intergenerational housing, or even an early return to it, is normatively supported in collectivistic cultures. Differences between the United States and Germany on the one hand, and China and Taiwan on the other, point to variation in welfare regimes and differences in urbanization.

    Hume, P A; Chalmers, D J; Wilson, B D

    1996-01-01

    OBJECTIVE: To examine trampoline related injuries resulting in emergency department attendance. METHODS: Cases were identified by searching free text descriptions of the circumstances of injury contained in the records of the emergency department of a large city hospital. RESULTS: 114 cases were identified for a 12 month period, giving an incidence rate of 108 per 100,000 population per year (95% confidence interval = 89 to 129) compared with 9.3 hospital admissions per 100,000 population per year (95% confidence interval = 8.3 to 10.4) for a corresponding period reported in earlier research from New Zealand. This suggested that for every one hospital admission there are approximately 12 emergency department attendances. Of the cases, 95% were aged less than 20 years. As for the earlier research, falls from the trampoline to the surrounding surface were the commonest cause of injury. In the present study, sprains and strains were the commonest type of injury (40%), and the body site most frequently involved was the lower limb (46%). CONCLUSIONS: The findings support the conclusion from earlier research that although existing trampoline standards address many of the issues relating to trampoline safety, the need remains for measures to reduce the impact of falls from the trampoline to the ground surface and to prohibit the use of trampolines as unsupervised "play equipment".

  2. Biogeochemical fingerprints of life: earlier analogies with polar ecosystems suggest feasible instrumentation for probing the Galilean moons

    We base our search for the right instrumentation for detecting biosignatures on Europa on the analogy suggested by the recent work on polar ecosystems in the Canadian Arctic at Ellesmere Island. In that location sulphur patches (analogous to the Europan patches) are accumulating on glacial ice lying over saline springs rich in sulphate and sulphide. Their work reinforces earlier analogies in Antarctic ecosystems that are appropriate models for possible habitats that will be explored by the European Space Agency JUpiter ICy Moons Explorer (JUICE) mission to the Jovian System. Its Jupiter Ganymede Orbiter (JGO) will include orbits around Europa and Ganymede. The Galileo orbital mission discovered surficial patches of non-ice elements on Europa that were widespread and, in some cases possibly endogenous. This suggests the possibility that the observed chemical elements in the exoatmosphere may be from the subsurface ocean. Spatial resolution calculations of Cassidy and co-workers are available, suggesting that the atmospheric S content can be mapped by a neutral mass spectrometer, now included among the selected JUICE instruments. In some cases, large S-fractionations are due to microbial reduction and disproportionation (although sometimes providing a test for ecosystem fingerprints, even though with Sim - Bosak - Ono we maintain that microbial sulphate reduction large sulphur isotope fractionation does not require disproportionation. We address the question of the possible role of oxygen in the Europan ocean. Instrument issues are discussed for measuring stable S-isotope fractionations up to the known limits in natural populations of δ34 ~ -70‰. We state the hypothesis of a Europa anaerobic oceanic population of sulphate reducers and disproportionators that would have the effect of fractionating the sulphate that reaches the low-albedo surficial regions. This hypothesis is compatible with the time-honoured expectation of Kaplan and co-workers (going back to the

  3. Higher dose rate Gamma Knife radiosurgery may provide earlier and longer-lasting pain relief for patients with trigeminal neuralgia.

    Gamma Knife radiosurgery (GKRS) utilizes cobalt-60 as its radiation source, and thus dose rate varies as the fixed source decays over its half-life of approximately 5.26 years. This natural decay results in increasing treatment times when delivering the same cumulative dose. It is also possible, however, that the biological effective dose may change based on this dose rate even if the total dose is kept constant. Because patients are generally treated in a uniform manner, radiosurgery for trigeminal neuralgia (TN) represents a clinical model whereby biological efficacy can be tested. The authors hypothesized that higher dose rates would result in earlier and more complete pain relief but only if measured with a sensitive pain assessment tool. One hundred thirty-three patients were treated with the Gamma Knife Model 4C unit at a single center by a single neurosurgeon during a single cobalt life cycle from January 2006 to May 2012. All patients were treated with 80 Gy with a single 4-mm isocenter without blocking. Using an output factor of 0.87, dose rates ranged from 1.28 to 2.95 Gy/min. The Brief Pain Inventory (BPI)-Facial was administered before the procedure and at the first follow-up office visit 1 month from the procedure (mean 1.3 months). Phone calls were made to evaluate patients after their procedures as part of a retrospective study. Univariate and multivariate linear regression was performed on several independent variables, including sex, age in deciles, diagnosis, follow-up duration, prior surgery, and dose rate. In the short-term analysis (mean 1.3 months), patients' self-reported pain intensity at its worst was significantly correlated with dose rate on multivariate analysis (p = 0.028). Similarly, patients' self-reported interference with activities of daily living was closely correlated with dose rate on multivariate analysis (p = 0.067). A 1 Gy/min decrease in dose rate resulted in a 17% decrease in pain intensity at its worst and a 22% decrease

    Full Text Available Objectives: To describe the profile of women with children aged under 4 months living in the Brazilian state capitals and in the Federal District according to their working status and to analyze the influence of maternity leave on exclusive breastfeeding (EBF among working women. Methods: This was a cross-sectional study with data extracted from the II National Maternal Breastfeeding Prevalence Survey carried out in 2008. Initially, a descriptive analysis of the profile of 12,794 women was performed, according to their working status and maternity leave and the frequency of maternity leave in the Brazilian regions and capitals. The study used a multiple model to identify the influence of maternity leave on EBF interruption, including 3766 women who declared they were working and were on maternity leave at the time of the interview. The outcome assessed in the study was the interruption of the EBF, classified by the WHO. Results: Regarding the working status of the mothers, 63.4% did not work outside of their homes and among those who worked, 69.8% were on maternity leave. The largest prevalence among workers was of women older than 35 years of age, with more than 12 years of schooling, primiparous and from the Southeast and South regions. The lack of maternity leave increased by 23% the chance of EBF interruption. Conclusion: Maternity leave contributed to increase the prevalence of EBF in the Brazilian states capitals, supporting the importance of increasing the maternity leave period from four to six months.

    Full Text Available Introduction. Almond (Amygdalus communis is a stone fruit, from the Rosaceae family, closest to the peach. It is spread throughout the entire Mediterranean region and afterwards to the Southwestern USA, Northern Africa, Turkey, Iran, Australia and South Africa. It is sensitive to wet conditions, and therefore is not grown in wet climates. Iran is located in the semi-arid region of the world. Because of its special tolerance to water stress, almond is one of the main agricultural products in rainfed condition in Iran. Almond leaves have been investigated for their phenolic content and antioxidant activity. It was found that total antioxidant activity and phenolic compounds exhibited variations according to season, plant organ (leaf and stem and variety. Analysis of previous research on almonds focused on investigating compounds mostly in seeds and phenolic compounds in leaves, but organic acids in leaves have not been studied. Aim of this study was investigation of organic acids in leaves of almond variety which is distributed in Razavi Khorasan province of Iran. Materials and Methods. In August 2012 almond leaves were collected in Iran, dried and grinded. The study of qualitative composition and quantitative determination of carboxylic acids in almond leaves was carried out by gas chromatography with mass spectrometric detection. For determination organic acids content, to 50 mg of dried plant material in 2 ml vial internal standard (50 μg of tridecane in hexane was added and filled up with 1.0 ml of methylating agent (14 % BCl3 in methanol, Supelco 3-3033. The mixture was kept in a sealed vial during 8 hours at 65 °C. At this time fatty oil was fully extracted, and hydrolyzed into its constituent fatty acids and their methylation was done. At the same time free organic and phenolcarbonic acids were methylated too. The reaction mixture was poured from the plant material sediment and was diluted with 1 ml of distilled water.

    The United States (US) is the only developed country that does not guarantee short-term or longer-term paid sick leave. This study used a multiyear nationally representative database to examine the association between availability of paid sick leave and frequency of emergency department (ED) use among US private sector employees. We used the National Health Interview Survey data (2012-2014). The final study sample consists of 42,460 US adults between 18 and 64years of age and working in nongovernmental private sector. Our results suggest that availability of paid sick leave is significantly associated with lower likelihood of ED use, for both moderate (1-3 times/year) and repeated users (4 or more times/year). After controlling for confounding factors, respondents with paid sick leave are 14% less likely to be moderate ED users (adjusted odds ratio, 0.86; 95% CI, 0.79-0.93) and 32% less likely to be repeated ED users (adjusted odds ratio, 0.68; 95% CI, 0.50-0.91). Although expansion of health insurance coverage under the Affordable Care Act has not been shown to reduce utilization of high cost health care services such as the ED, our study suggests other factors such as the availability of paid sick leave may do so, by allowing patients to seek care through other more cost-effective mechanisms (eg, primary care providers). To reduce ED utilization, health policymakers should consider alternative reforms including paid sick leave. Copyright © 2016 Elsevier Inc. All rights reserved.

  14. Biogenic volatile organic compound emissions from senescent maize leaves and a comparison with other leaf developmental stages

    Plants are the major source of Biogenic Volatile Organic Compounds (BVOCs) which have a large influence on atmospheric chemistry and the climate system. Therefore, understanding of BVOC emissions from all abundant plant species at all developmental stages is very important. Nevertheless, investigations on BVOC emissions from even the most widespread agricultural crop species are rare and mainly confined to the healthy green leaves. Senescent leaves of grain crop species could be an important source of BVOCs as almost all the leaves senesce on the field before being harvested. For these reasons, BVOC emission measurements have been performed on maize (Zea mays L.), one of the most cultivated crop species in the world, at all the leaf developmental stages. The measurements were performed in controlled environmental conditions using dynamic enclosures and proton transfer reaction mass spectrometry (PTR-MS). The main compounds emitted by senescent maize leaves were methanol (31% of the total cumulative BVOC emission on a mass of compound basis) and acetic acid (30%), followed by acetaldehyde (11%), hexenals (9%) and m/z 59 compounds (acetone/propanal) (7%). Important differences were observed in the temporal emission profiles of the compounds, and both yellow leaves during chlorosis and dry brown leaves after chlorosis were identified as important senescence-related BVOC sources. Total cumulative BVOC emissions from senescent maize leaves were found to be among the highest for senescent Poaceae plant species. BVOC emission rates varied strongly among the different leaf developmental stages, and senescent leaves showed a larger diversity of emitted compounds than leaves at earlier stages. Methanol was the compound with the highest emissions for all the leaf developmental stages and the contribution from the young-growing, mature, and senescent stages to the total methanol emission by a typical maize leaf was 61, 13, and 26%, respectively. This study shows that BVOC

    Mitoxantrone (MTX) is a chemotherapeutic agent that emerged as an alternative to anthracycline therapy. However, MTX also causes late cardiotoxicity, being oxidative stress and mitochondrial-impaired function proposed as possible mechanisms. This work aimed to investigate the relevance of these mechanisms to the MTX toxicity in H9c2 cells, using therapeutic concentrations. The observed cytotoxicity of MTX was time and concentration dependent in both lactate dehydrogenase leakage assay and MTT reduction assay. Two therapeutic concentrations (100 nM and 1 μM) and three time points were selected (24, 48, and 96 h) for further studies. Both MTX concentrations caused a significant increase in caspase-3 activity, which was not prevented by inhibiting MTX CYP450-metabolism. Significant decreases were observed in the total and reduced glutathione levels only in MTX 100 nM at 96 h; however, neither alterations in oxidized glutathione nor increases in the malondialdehyde levels were observed at any time or concentrations tested. On the other hand, changes in the intracellular ATP levels, mitochondrial membrane potential, and intracellular calcium levels were observed in both concentrations and all time tested. Noteworthy, decreased levels of ATP-synthase expression and activity and increases in the reactive species generation were observed at 96 h in both working concentrations. However, the radical scavenger N-acetylcysteine or the mitochondrial function enhancer L-carnitine did not prevent MTX cytotoxicity. Thus, this work evidenced the early MTX-induced energetic crisis as a possible key factor in the cell injury.

    Due to complex orography and air mass circulation, the Rijeka Bay area is characterized by O3 gradient, with concentrations risen with the altitude (1). Therefore AOT40 values were often exceeded and should result in harmful effects on vegetation. Based on previous controlled experiments (2), we examined the possible effect of atmospheric ozone on grape leaves under natural O3 gradient. Grapevine leaves (2-5) were collected from May to September 2016 at two sampling points in the proximity of two AQM stations: Site 1 in the city centre (20m asl) and Site 2 (186m asl) in the suburban settlement. Subsequent to weighing and determination of surface area, the leaves (0,5 g) were extracted in 95% ethanol and analysed on chlorophyl a (Chla), chlorophyl b (Chlb) and carotene (Car) content by UV-VIS spectrometry on 3 wavelengths (664, 649, 470 nm) (3) In summer 2016 O3 gradient was not that pronounced as usual (1), but stil the concentrations differed by approx. 20%, exceeding national AOT40 value at both sites (22.360 and 28.061 μg m-3 h, respectively, at Sites 1 and 2). The concentrations of other pollutants were bellow limit values (LV). The Cha and Chb in a sample leaves collected at the end of May at Site 2 are equal to that with filtered O3 in control experiment (2), i.e. without damage caused by ozone, while the Car content is lower approx. 50% and is kept at the same level. The con-centrations of pigments obtained in July prooved the possible damage by O3, while in subsequent months could speed up natural ageing. This is the first evidence of O3 damage on plants in the Rijeka Bay area, in spite of weaker O3 gradient and lacking visible signs of damage. Preliminary results indicate the need for more frequent sampling, particularly in the period included in AOT40 (May-July). References: 1.

    2010-07-01

    Tactical emergency medicine services (TEMS) has emerged as a specialized niche within the field of emergency medicine. With increasing demand for physician participation in civilian tactical teams, there will be efforts by residents to become involved at earlier points in their clinical training. This article discusses resident involvement with a civilian TEMS unit and provides five maxims for emergency physicians to better understand the difference between working in the emergency department or with emergency medical services vs. in a TEMS environment. Differences between TEMS and other trauma life support models, institutional and political barriers likely to be encountered by the resident, the value of preventive medicine and the role of the physician in long-term tactical operations, opportunities for subspecialty growth, and the role of operational security are all discussed in detail. Tactical emergency medicine is a specialty that utilizes the full array of the emergency physician's skill set. It is also a field that is ripe for continued expansion, but the resident looking to become involved with a team should be aware of the requirements necessary to do so and the obstacles likely to be encountered along the way.

    2014-01-01

    Early return to work after childbirth has been increasing among working mothers in the US. We assessed the relationship between access to employer-offered maternity leave (EOML) (both paid and unpaid) and uptake and duration of maternity leave following childbirth in a socio-economically diverse sample of full-time working women. We focus on California, a state that has long provided more generous maternity leave benefits than those offered by federal maternity leave policies through the State Disability Insurance program. The sample included 691 mothers who gave birth in Southern California in 2002-2003. Using weighted logistic regression, we examined the EOML-maternity leave duration relationship, controlling for whether the leave was paid, as well as other occupational, personality and health-related covariates. Compared with mothers who were offered more than 12 weeks of maternity leave, mothers with leave had six times higher odds of an early return. These relationships were similar after controlling for whether the leave was paid and after controlling for other occupational and health characteristics. Access to and duration of employer-offered maternity leave significantly determine timing of return to work following childbirth, potentially affecting work-family balance. Policy makers should recognize the pivotal role of employers in offering job security during and after maternity leave and consider widening the eligibility criteria of the Family and Medical Leave Act.

    Twitter is one of the fastest growing social media networks for communication between users via short messages. Technology proficient physicians have demonstrated enthusiasm in adopting social media for their work. To identify and create the largest directory of emergency physicians on Twitter, analyse their user accounts and reveal details behind their connections. Several web search tools were used to identify emergency physicians on Twitter with biographies completely or partially written in English. NodeXL software was used to calculate emergency physicians' Twitter network metrics and create visualisation graphs. The authors found 672 Twitter accounts of self-identified emergency physicians. Protected accounts were excluded from the study, leaving 632 for further analysis. Most emergency physicians were located in USA (55.4%), had created their accounts in 2009 (43.4%), used their full personal name (77.5%) and provided a custom profile picture (92.2%). Based on at least one published tweet in the last 15 days, there were 345 (54.6%) active users on 31 December 2011. Active users mostly used mobile devices based on the Apple operating system to publish tweets (69.2%). Visualisation of emergency physicians' Twitter network revealed many users with no connections with their colleagues, and a small group of most influential users who were highly interconnected. Only a small proportion of registered emergency physicians use Twitter. Among them exists a smaller inner network of emergency physicians with strong social bonds that is using Twitter's full potentials for professional development.

    from psychiatric hospitals, drug treatment centers and emergency departments, and studies that discussed misuse of alcohol but not illicit drugs. Data collection and analysis. We created an electronic database that included study abstracts and relevant information matching the keywords and search criteria. We reviewed potentially eligible articles independently by scanning the titles, abstracts, and full texts of articles after removing duplicates. We identified studies for which eligibility was unclear and decided which studies to include after thoroughly reviewing and discussing them. Results. Of the 1649 studies that matched the search criteria, 17 met our inclusion criteria. Thirteen studies identified substance misuse as a significant predictor of leaving the hospital against medical advice. Three studies assessed the prevalence and predictors of leaving the hospital against medical advice among people who inject drugs and found that this phenomenon was commonly reported (prevalence range = 25%–30%). Factors positively associated with leaving the hospital against medical advice included recent injection drug use, Aboriginal ancestry, leaving on weekends and welfare check day. In-hospital methadone use, social support, older age, and admission to a community-based model of care were negatively associated with the outcome. Conclusions. To better understand risk factors associated with leaving the hospital against medical advice among PWUD, future research should consider the effect of individual, social, and structural characteristics on leaving the hospital against medical advice among PWUD. The development and evaluation of novel methods to address interventions to reduce the rate of leaving the hospital prematurely is necessary. PMID:26469651

    Symptoms of ozone injury were observed on older leaves of potato cultivars Norland and Katahdin under experimental conditions. This symptom expression closely resembled flecks observed on potato leaves also blighted by Botrytis cinerea in the field. Inoculation of ozone-injured and noninjured potato leaves with B. cinerea showed that infection was more rapid and disease development more severe on ozone-injured leaves. Infection was frequently observed to originate in ozone-injured leaf areas. Ozone injury, under experimental conditions, appeared to increase the susceptibility of potato leaves to infection by B. cinerea. 6 references.

    In 1987, the American Association of Women Radiologists surveyed both academic and private radiology departments regarding pregnancy and maternity leave policies. One hundred academic institutions (70% response), 30 radiotherapy departments (38% response), and 31 private practices responded. Details were obtained regarding maternity leave policy for residents and attending physicians; availability of paternity leave; policies regarding on-call time, fluoroscopy time and intracavitary/interstitial applications during pregnancy; and problems that occurred during resident or attending physician pregnancies. There was a wide range of responses regarding paid leave time, availability of additional time, and the use of vacation time during maternity leave

    The seasonality of vegetation, i.e., developmental stages and phenological processes, affects the emission of volatile organic compounds (VOCs). Despite the potential significance, the contributions of seasonality to VOC emission quality and quantity are not well understood and are therefore often ignored in emission simulations. We investigated the VOC emission patterns of young and mature leaves of several Mediterranean plant species in relation to their physiological and developmental changes during the growing period and estimated Es. Foliar emissions of isoprenoids and oxygenated VOCs like methanol and acetone were measured online by means of a proton transfer reaction mass spectrometer (PTR-MS) and offline with gas chromatography coupled with a mass spectrometer and flame ionization detector. The results suggest that VOC emission is a developmentally regulated process and that quantitative and qualitative variability is plant species specific. Leaf ontogeny clearly influenced both the VOC Es and the relative importance of different VOCs. Methanol was the major compound contributing to the sum of target VOC emissions in young leaves (11.8 ± 10.4 μg g-1 h-1), while its contribution was minor in mature leaves (4.1 ± 4.1 μg g-1 h-1). Several plant species showed a decrease or complete subsidence of monoterpene, sesquiterpene, and acetone emissions upon maturity, perhaps indicating a potential response to the higher defense demands of young emerging leaves.

    2013-01-01

    In 2010 the University of Wisconsin - Madison Astronomy Department developed and implemented a departmental paid leave policy for our graduate students, even though the university lacks a campus-wide policy and cannot provide institutional funding for such programs. This policy includes 12 weeks of paid leave in event of a medical emergency or chronic medical condition, as well as paid parental leave for both male and female graduate research assistants. (The policy in its entirety can be found at http://www.astro.wisc.edu/grad-students/policies-procedures/medical-and-family-leave-policy.) This is the first of two presentations describing our policy implementation using a "bottom-up" approach, beginning with the graduate students. I will present the perspective of the graduate students who led the effort and will discuss the steps we took to put our policy in place, from the conception of the plan to the full implementation. These steps included identifying faculty allies, becoming knowledgeable about university policies and resources, involving department staff, and anticipating procedural and bureaucratic hurdles in order to come up with creative solutions in advance. Although each individual institution and department's path to implementing a similar plan will be unique, we hope the methods used to implement our policy at UW - Madison may serve as an example.

  15. The neglected shadow: European perspectives on emotional supports for early school leaving prevention

    Full Text Available OECD reports emphasise ten key steps to equity in education, with concrete targets related to low attainment and early school leaving. Such steps, however, neglect the importance of emotional dimensions to early school leaving and the consequent need for system level emotional supports. The current study involves qualitative research interviews with senior government officials and secondary school management representatives across eight European countries, with a particular focus on school climate and emotional support issues. Issues raised by interviewees for students at risk of early school leaving include supports for withdrawn children, for those at risk of suicide and those being bullied at school affecting their nonattendance. Other emerging themes include alternatives to suspension and teacher education for improving their conflict resolution skills. Some interviewees explicitly observe the dearth of emotional support services available in practice in their countries. The pervasive policy gaps across national levels for a mental health and emotional support strategy, as part of an early school leaving prevention strategy, requires serious and immediate attention.

    Full Text Available Bioelectrical potentials of the plants during photostimulation with various intensity values and wave lengths are studied. Suchstimulation provides light-dependent reactions of photosynthesis. The universal scheme of registration of bioelectric potentials, which allowsto carry out the experimental study of light stimuli effect on the plant is proposed. All registrations of potentials are observed on the pepper leaves. Photoinduced stimuli are different with intensity changed from 150 to 450 lux and different spectrums of white light and red light with wave length 690 nm. Different parameters of stimuli drive to different types of biopotentials of the plant, quantitative and qualitative relationships of this process are obtained. It is also found that bioelectrical reaction of the leaves is quantitatively different in various spectral ranges of light, but the quality remains the same for all cases, as shown in the study of bioelectric responses during exposure to the light in red spectrum range. The explanation of the additional depolarization phase that occurs during the running of dark reparative process of photosynthesis is given. Light-dependent reactions of photosynthesis are accompanied by significant changes in the electrical potential of chloroplasts’ membrane. Besides, the dependence of bioelectrical reaction of the plant on different spectra of light is found. By this way, biophysical relation of plant potentials to the intracellular biophysical mechanisms during photo stimulation is obtained.

  17. Enhancing Water Evaporation with Floating Synthetic Leaves

    When a wetted nanoporous medium is exposed to a subsaturated ambient environment, the water menisci assume a concave curvature to achieve a negative pressure. This negative water pressure is required to balance the mismatch in water activity across the water-air interface to achieve local equilibrium. Here, we show that the diffusive evaporation rate of water can be greatly modulated by floating a nanoporous synthetic leaf at the water's free interface. For high ambient humidities, adding the leaf serves to enhance the evaporation rate, presumably by virtue of the menisci enhancing the effective liquid-vapor surface area. For low humidities, the menisci cannot achieve a local equilibrium and retreat partway into the leaf, which increases the local humidity directly above the menisci. In light of these two effects, we find the surprising result that leaves exposed to an ambient humidity of 90 percent can evaporate water at the same rate as leaves exposed to only 50 percent humidity. These findings have implications for using synthetic trees to enhance steam generation or water harvesting. This work was supported by the National Science Foundation (CBET-1653631).

    We study the relationship between the length of maternity leave and the physical and psychological health of the family. Using a reform of the parental leave scheme in Denmark that increased the number of weeks of leave with full benefit compensation, we estimate the effect of the lenght...... of maternity leave on a range of health indicators including the number of hospital admissions for both mother and child and the probability of the mother receiving antidepressants. The reform led to an increase in average post-birth maternity leave matters for child or maternal health outcomes and thus we...... complement the existing evidence on maternity leave expansions that tends to find limited effects on children's later deveopmental, educational, and labor market outcomes. Our results suggest that any beneficial effects of increasing the lenght of maternity leave are greater for low-resource families....

    Enhanced team communication may strengthen nurses' attachment to their organizations and teams and improve nurse retention. This study examines the relationships among nurse-team communication, identification (organizational and team), and intent to leave. Hospital nurses (N = 201) completed surveys measuring 3 nurse-team communication processes: promoting team synergy, ensuring quality decisions, and individualizing communication. Hierarchical regression analyses revealed that promoting team synergy was a significant predictor of intent to leave, whereas ensuring quality decisions and individualizing communication did not account for significant additional variance in intent to leave. Separate analyses showed that the relationship between promoting team synergy and intent to leave was partially mediated by team identification or by organizational identification. Further analyses were conducted on the 7 communication practices for promoting team synergy. Mentoring emerged as the only significant predictor of intent to leave; however, its relationship to intent to leave was fully mediated by organizational identification or partially mediated by team identification. Pragmatic suggestions are offered to improve nurse identification and reduce turnover.

    Full Text Available Background: Staff retention and turnover have risen in prominence in the global discourse on the health workforce. Moonlighting, having a second job in addition to a primary job, has not featured in debates on turnover. Objective: This paper examines whether moonlighting is a determinant of South African nurses’ intention to leave their primary jobs. Design: During 2010, a one-stage cluster random sample of 80 hospitals was selected in four South African provinces. On the survey day, all nurses working in critical care, theatre, emergency, maternity, and general medical and surgical wards completed a self-administered questionnaire after giving informed consent. In addition to demographic information and information on moonlighting, the questionnaire obtained information on the participants’ intention to leave their primary jobs in the 12 months following the survey. A weighted analysis of the survey data was done using STATA® 13. Results: Survey participants (n=3,784 were predominantly middle-aged with a mean age of 41.5 (SD±10.4 years. Almost one-third of survey participants (30.9% indicated that they planned to leave their jobs within 12 months. Intention to leave was higher among the moonlighters (39.5% compared to non-moonlighters (27.9%; p<0.001. Predictors of intention to leave in a multiple logistic regression were moonlighting in the preceding year, nursing category, sector of primary employment, period working at the primary job, and number of children. The odds of intention to leave was 1.40 (95% CI: 1.16–1.69 times higher for moonlighters than for non-moonlighters. The odds ratio of intention to leave was 0.53 (95% CI: 0.42–0.66 for nursing assistants compared to professional nurses and 2.09 (95% CI: 1.49–2.94 for nurses working for a commercial nursing agency compared to those working in the public sector. Conclusions: Moonlighting is a predictor of intention to leave. Both individual and organisational strategies are

    Disaster relief can be seen as a dynamic multi actor process with actors both joining and leaving the relief work during the help and rescue phase after the disaster has occurred. Actors may be governmental agencies, non profit voluntary organisations or spontaneous helpers comprised of individual citizens or temporal groups of citizens. Hence, they will vary widely in agility, competence, resources, and endurance. To prepare for for disasters a net based Agora with simulation of emergency situations for mutual preparation, training, and organisational learning is suggested. Such an Agora will ensure future security by: -Rising awareness and preparedness of potential disaster responders by help of the components and resources in the netAgora environment; -Improving cooperation and coordination between responders; -Improving competence and performance of organisations involved in security issues; -Bridging cultural differences between responders from different organizations and different backgrounds. The developed models are intended to reflect intelligent anticipatory systems for human operator anticipation of future consequences. As a way to catch what should be included in this netbased Agora and to join the split pictures that is present, Team Syntegrity could be a helpful tool. The purpose of Team Syntegrity is to stimulate collaboration and incite cross fertilization and creativity. The difference between syntegration and other group work is that the participants are evenly and uniquely distributed and will collectively have the means, the knowledge, the experience, the perspectives, and the expertise, to deal with the topic. In this paper the possibilities with using Team Syntegrity in preparation for the development of a netbased Agora is discussed. We have identified that Team Syntegrity could be useful in the steps User Integration, Designing the netAgora environment, developing Test Scenarios, and assessment of netAgora environment.

    Malaria is one of the leading causes of death in the world which is caused by Plasmodium sp. This parasite tends to have mutation and shows resistance towards malaria drug. Due to the emergence and spread of Plasmodium sp. resistance towards malaria drugs, an exploration to find new effective and selective malaria drug is essential. In this study, four flavonoids, namely nymphaeol C (1), solophenol D (2), nymphaeol A (3), and nymphaeol B (4) were isolated from ethyl acetate fraction of Macaranga tanarius leaves. The structures of those compounds were characterized by NMR analysis. Furthermore, antiplasmodial activity of ethyl acetate fraction and four isolated compounds (1–4) were evaluated by Giemsa method against Plasmodium falciparum strain 3D7. According to this assay, it showed the IC50 values were 0.30, 0.24, 0.31, 0.05, and 0.05 μg/mL, respectively. The results provide important evidence of the antiplasmodial activity of flavonoids in traditional use. In addition, it can be indicated that Macaranga tanarius is potential to be developed as antiplasmodial agents.

    Phytoremediation is a cost-effective plant-based approach for remediation of soils and waters which takes advantage of the remarkable ability of some plants to concentrate elements and compounds from the environment and to metabolize various molecules in their tissues, such as toxic heavy metals and organic pollutants. Nowadays, phytoremediation technology is becoming of paramount importance when environmental decontamination is concerned, due to the emerging knowledge of its physiological and molecular mechanisms and the new biological and engineering strategies designed to optimize and improve it. In addition, the feasibility of using plants for environmental cleanup has been confirmed by many different trials around the world. Arabidopsis thaliana plants can be used for basic studies to improve the technology on phytoremediation. Making use of nuclear microscopy techniques, in this paper we study leaves of wild type and transgenic A. thaliana plants grown in a cadmium-rich environment under different conditions. Micro-PIXE, RBS and SEM analyses, performed on the scanning proton micro-probe at the CNA in Seville (Spain), prove that cadmium is preferentially sequestered in the central region of epidermal trichome and allow comparing the effects of genetic modifications

    Knowledge about influenza transmission in the workplace and whether staying home from work when experiencing influenza-like illness can reduce the spread of influenza is crucial for the design of efficient public health initiatives. This review synthesizes current literature on sickness presenteeism and influenza transmission in the workplace and provides an overview of sick leave recommendations in Europe for influenza. A search was performed on Medline, Embase, PsychINFO, Cinahl, Web of Science, Scopus and SweMed to identify studies related to workplace contacts, -transmission, -interventions and compliance with recommendations to take sick leave. A web-based survey on national recommendations and policies for sick leave during influenza was issued to 31 European countries. Twenty-two articles (9 surveys; 13 modelling articles) were eligible for this review. Results from social mixing studies suggest that 20-25% of weekly contacts are made in the workplace, while modelling studies suggest that on average 16% (range 9-33%) of influenza transmission occurs in the workplace. The effectiveness of interventions to reduce workplace presenteeism is largely unknown. Finally, estimates from studies reporting expected compliance with sick leave recommendations ranged from 71 to 95%. Overall, 18 countries participated in the survey of which nine (50%) had issued recommendations encouraging sick employees to stay at home during the 2009 A(H1N1) pandemic, while only one country had official recommendations for seasonal influenza. During the 2009 A(H1N1) pandemic, many European countries recommended ill employees to take sick leave. Further research is warranted to quantify the effect of reduced presenteeism during influenza illness. © The Author 2016.

    Full Text Available The chemical components of essential oils derived from leaves and flowers of Lantana camara growing in Saudi Arabia are analyzed for the first time using gas chromatography techniques (GC–MS, GC–FID, Co-GC, LRI determination, and database and literature searches on two different stationary phase columns (polar and nonpolar. This analysis led to the identification of total 163 compounds from leaves and flowers oils. 134 compounds were identified in the oil obtained from leaves of L. camara, whereas 127 compounds were identified in the oil obtained from flowers; these compounds account for 96.3% and 95.3% of the oil composition, respectively. The major components in the oil from leaves were cis-3-hexen-1-ol (11.3%, 1-octen-3-ol (8.7%, spathulenol (8.6%, caryophyllene oxide (7.5% and 1-hexanol (5.8%. In contrast, the major compounds in the flowers oil were caryophyllene oxide (10.6%, β-caryophyllene (9.7%, spathulenol (8.6%, γ-cadinene (5.6% and trans-β-farnesene (5.0%. To the best of our knowledge, cis-3-hexen-1-ol and 1-octen-3-ol that were identified as major components in this study have not been reported earlier from Lantana oils.

    To survey program directors in obstetrics and gynecology regarding maternity leave and to determine how programs are dealing with maternity leave coverage. Questionnaires regarding impact and policy on maternity leave were mailed to accredited obstetrics and gynecology residency programs. A total of 188 of 274 (69%) questionnaires were returned completed. Respectively, 80% and 69% of respondents indicated that they have a formal maternity (maximum mean 8.7 weeks) and paternity (mean 5.27 days) leave policy. Approximately 75% of programs require residents to make up time if their leave exceeds 8 weeks during the first 3 years. Eighty-five percent of programs require residents to make up time if their leave exceeds 6 weeks during the fourth year. Ninety-three percent of programs require residents to make up time if their leave exceeds 20 weeks over the 4 years. Seventy-seven percent of respondents have other residents in their program cover for the absent resident. Thirty-seven percent of programs have schedules flexible enough to allow rearrangement so that some rotations go uncovered. Eighty-three percent of programs surveyed stated that maternity leave has a somewhat to very significant impact on the residents' schedules. Most residency programs have written maternity/paternity leave policies. A more flexible curriculum may help to accommodate the residents on leave without overburdening the residents who are left to cover.

    Pregnancy and maternity are increasingly viewed as social as well as individual risks that require health protection, employment protection and security, and protection against temporary loss of income. Begun more than a century ago in Germany, paid and job-protected maternity leaves from work were established in most countries initially out of concern for maternal and child physical health. Beginning in the 1960s, these policies have expanded to cover paternity and parental leaves following childbirth and adoption as well. Moreover, they have increasingly emerged as central to the emotional and psychological well-being of children as well as to the employment and economic security of their mothers and fathers. They are modest social policies, but are clearly an essential part of any country's child and family policy. No industrialized country today can be without such provision, and the United States is a distinct laggard in these developments.

    Urban animals inhabit an environment considerably different than do their non-urban conspecifics, and to persist urban animals must adjust to these novel environments. The timing of seasonal reproductive development (i.e., growth of gonads and secondary sex organs) is a fundamental determinant of the breeding period and is frequently advanced in urban bird populations. However, the underlying mechanism(s) by which birds adjust the timing of reproductive development to urban areas remain(s) largely unknown. Here, we compared the timing of vernal reproductive development in free-ranging urban and non-urban male Abert's Towhees, Melozone aberti, in Phoenix, Arizona, USA, and tested the non-mutually exclusive hypotheses that earlier reproductive development is due to improved energetic status and/or earlier increase in endocrine activity of the reproductive system. We found that urban birds initiated testicular development earlier than non-urban birds, but this disparity was not associated with differences in body condition, fat stores, or innate immune performance. These results provide no support for the hypothesis that energetic constraints are responsible for delayed reproductive development of non-urban relative to urban male Abert's Towhees. Urban birds did, however, increase their plasma luteinizing hormone, but not plasma testosterone, earlier than non-urban birds. These findings suggest that adjustment to urban areas by Abert's Towhees involves increases in the endocrine activity of the anterior pituitary gland and/or hypothalamus earlier than non-urban towhees.

The leaves falling model has a widely applications in the field of animation and virtual reality. We propose a novel modeling method of fluttering leaves based on point cloud in this paper. According to the shape, the weight of leaves and the wind speed, three basic trajectories of leaves falling are defined, which are the rotation falling, the roll falling and the screw roll falling. At the same time, a parallel algorithm based on OpenMP is implemented to satisfy the needs of real-time in practical applications. Experimental results demonstrate that the proposed method is amenable to the incorporation of a variety of desirable effects.

    Street intersections that are equipped with traffic lights would also be equipped with means for generating audible announcements of approaching emergency vehicles, according to a proposal. The means to generate the announcements would be implemented in the intersection- based subsystems of emergency traffic-light-preemption systems like those described in the two immediately preceding articles and in "Systems Would Preempt Traffic Lights for Emergency Vehicles" (NPO-30573), NASA Tech Briefs, Vol. 28, No. 10 (October 2004), page 36. Preempting traffic lights is not, by itself, sufficient to warn pedestrians at affected intersections that emergency vehicles are approaching. Automated visual displays that warn of approaching emergency vehicles can be helpful as a supplement to preemption of traffic lights, but experience teaches that for a variety of reasons, pedestrians often do not see such displays. Moreover, in noisy and crowded urban settings, the lights and sirens on emergency vehicles are often not noticed until a few seconds before the vehicles arrive. According to the proposal, the traffic-light preemption subsystem at each intersection would generate an audible announcement for example, emergency vehicle approaching, please clear intersection whenever a preemption was triggered. The subsystem would estimate the time of arrival of an approaching emergency vehicle by use of vehicle identity, position, and time data from one or more sources that could include units connected to traffic loops and/or transponders connected to diagnostic and navigation systems in participating emergency vehicles. The intersection-based subsystem would then start the announcement far enough in advance to enable pedestrians to leave the roadway before any emergency vehicles arrive.

  3. Is part-time sick leave helping the unemployed?

    1980-01-01

    Chemical analysis on cacao leaves that have chlorosis spots caused by cocoa swollen shoot viruses were carried out. It can be shown that leaves with chlorosis spots contain less chlorophyl and lipides than those without, but both do not show any significant difference in the concentration of water, glucose, saccharides, amino acid and proteins. It can be concluded that transport systems in the infected leaves are good so that the water and saccharides distribution in them are not disturbed. (author tr.)

  5. Abscisic acid protects bean leaves from ozone-induced phytotoxicity

    Energy Technology Data Exchange (ETDEWEB)

    Fletcher, R.A.; Adedipe, N.O.; Ormrod, D.P.

    1972-01-01

    Abscisic acid treatment of primary bean leaves caused a partial closure of stomates and thus considerably reduced the phytotoxicity of ozone. The symptoms of ozone-induced phytotoxicity in the water-treated leaves are a marked decrease in chlorophyll and slight decreases in the levels of protein and RNA. The evidence indicates that ozone injury to leaves is not metabolically related to normal leaf senescence.

  6. The Duration of Paid Parental Leave and Children's Scholastic Performance

    2009-01-01

    We study how the duration of paid parental leave affects the accumulation of cognitive skills among children. We use a reform which extended parental leave benefits from 12 to 15 months for Swedish children born after August 1988 to evaluate the effects of prolonged parental leave on children's test scores and grades at age 16. We show that, on average, the reform had no effect on children's scholastic performance. However, we do find positive effects for children of well-educated mothers, a ...

    2015-08-01

    The American Academy of Pediatrics (AAP) states that each residency program should have a clearly delineated, written policy for parental leave. Parental leave has important implications for trainees' ability to achieve their breastfeeding goals. This study aimed to measure the knowledge and awareness among members of the AAP Section on Medical Students, Residents, and Fellowship Trainees (SOMSRFT) regarding parental leave. An online survey was emailed to SOMSRFT members in June 2013. Quantitative data are presented as percentage of respondents. Awareness of leave policies was analyzed based on having children and the sex of respondents. Nine hundred twenty-seven members responded to the survey. Among those with children, 40% needed to extend the duration of their training in order to have longer maternity leave, 44% of whom did so in order to breastfeed longer. Thirty percent of respondents did not know if their program had a written, accessible policy for parental leave. Trainees without children and men were more unaware of specific aspects of parental leave such as eligibility for the Family Medical Leave Act as compared to women and those with children. Despite the fact that United States national policies support parental leave during pediatrics training, and a majority of programs comply, trainees' awareness regarding these policies needs improvement. © The Author(s) 2015.

    Full Text Available Atmospheric pollution caused by toxic elements is an emerging problem of concern. Tree leaves have been widely used as indicator of atmospheric pollutions and they are effective alternatives to the moreusual biomonitoring methods. Tree leaves can be used as natural traps of atmospheric deposition. Elemental composition of dust deposited onto leaf surfaces can be used to characterize the urban environment. A pilot survey including 16 Romanian settlements was carried out in order to evaluate the characteristics and sources of air pollutants. Tree leaves (Tilia tomentosa, Tilia cordata, Tilia platyphyllos were collected and used for the measurements. Elemental analyses were carried out by ICP-OES and ICP-MS. Principal component and discriminant analyses were used to characterizing and estimating the level of pollution. Settlements were grouped on the basis of discriminant function values. Multivariate comparison of chemical data ordered the settlements into 3 main groups, which showed a systematic geographic distribution.

    2014-01-01

    Background Staff retention and turnover have risen in prominence in the global discourse on the health workforce. Moonlighting, having a second job in addition to a primary job, has not featured in debates on turnover. Objective This paper examines whether moonlighting is a determinant of South African nurses’ intention to leave their primary jobs. Design During 2010, a one-stage cluster random sample of 80 hospitals was selected in four South African provinces. On the survey day, all nurses working in critical care, theatre, emergency, maternity, and general medical and surgical wards completed a self-administered questionnaire after giving informed consent. In addition to demographic information and information on moonlighting, the questionnaire obtained information on the participants’ intention to leave their primary jobs in the 12 months following the survey. A weighted analysis of the survey data was done using STATA® 13. Results Survey participants (n=3,784) were predominantly middle-aged with a mean age of 41.5 (SD±10.4) years. Almost one-third of survey participants (30.9%) indicated that they planned to leave their jobs within 12 months. Intention to leave was higher among the moonlighters (39.5%) compared to non-moonlighters (27.9%; pleave in a multiple logistic regression were moonlighting in the preceding year, nursing category, sector of primary employment, period working at the primary job, and number of children. The odds of intention to leave was 1.40 (95% CI: 1.16–1.69) times higher for moonlighters than for non-moonlighters. The odds ratio of intention to leave was 0.53 (95% CI: 0.42–0.66) for nursing assistants compared to professional nurses and 2.09 (95% CI: 1.49–2.94) for nurses working for a commercial nursing agency compared to those working in the public sector. Conclusions Moonlighting is a predictor of intention to leave. Both individual and organisational strategies are needed to manage moonlighting and to enhance retention

    Background: In the earlier studies, methanolic extract of Mangifera indica L leaf was exhibited hypocholesterol activity. However, the bioactive compounds responsible for the same are not reported so far. Objective: To isolate the bioactive compounds with hypocholesterol activity from the leaf extract using cholesterol esterase inhibition assay which can be used for the standardization of extract. Materials and Methods: The leaf methanolic extract of M. indica (Sindoora variety) was partitioned with ethyl acetate and chromatographed on silica gel to yield twelve fractions and the activity was monitored by using cholesterol esterase inhibition assay. Active fractions were re-chromatographed to yield individual compounds. Results and Discussion: A major compound mangiferin present in the extract was screened along with other varieties of mango leaves for cholesterol esterase inhibition assay. However, the result indicates that compounds other than mangiferin may be active in the extract. Invitro pancreatic cholesterol esterase inhibition assay was used for bioactivity guided fractionation (BAGF) to yield bioactive compound for standardization of extract. Bioactivity guided fractionation afford the active fraction containing 3b-taraxerol with an IC50 value of 0.86μg/ml. Conclusion: This study demonstrates that M. indica methanol extract of leaf have significant hypocholesterol activity which is standardized with 3b-taraxerol, a standardized extract for hypocholesterol activity resulted in development of dietary supplement from leaves of Mangifera indica.

    Diabetes mellitus is a chronic metabolic disorder and has been associated with cognitive dysfunction. In our earlier study, chronic Urtica dioica (UD) treatment significantly ameliorated diabetes induced associative and spatial memory deficit in mice. The present study was designed to explore the effect of UD leaves extract on muscarinic cholinergic system, which has long been known to be involved in cognition. Streptozotocin (STZ) (50 mg/kg, i.p., consecutively for 5 days) was used to induce diabetes followed by treatment with UD extract (50 mg/kg, oral) or rosiglitazone (5 mg/kg, oral) for 8 weeks. STZ-induced diabetic mice showed significant reduction in hippocampal muscarinic acetylcholine receptor-1 and choline acetyltransferase expressions. Chronic diabetes significantly up-regulated the protein expression of acetylcholinesterase associated with oxidative stress in hippocampus. Besides, STZ-induced diabetic mice showed hypolocomotion with up-regulation of muscarinic acetylcholine receptor-4 expression in striatum. Chronic UD treatment significantly attenuated the cholinergic dysfunction and oxidative stress in the hippocampus of diabetic mice. UD had no effect on locomotor activity and muscarinic acetylcholine receptor-4 expression in striatum. In conclusion, UD leaves extract has potential to reverse diabetes mediated alteration in muscarinic cholinergic system in hippocampus and thereby improve memory functions.

  16. Emergency cooling system for a gas-cooled nuclear reactor

    1975-01-01

    The site of the gas-cooled reactor with direct-circuit gas turbine is preferably the sea coast. An emergency cooling system with safety valve and emergency feed-water addition is designed which affects at least a part of the reactor core coolant after leaving the core. The emergency cooling system includes a water emergency cooling circuit with heat exchanger for the core coolant. The safety valve releases water or steam from the emergency coolant circuit when a certain temperature is exceeded; this is, however, replaced by the emergency feed-water. If the gas turbine exhibits a high and low pressure turbine stage, which are flowed through by coolant one behind another, a part of the coolant can be removed in front of each part turbine by two valves and be added to the haet exchanger.

    2015-03-01

    Full Text Available Background: Little is known about the prevalence of sick leave due to atopic dermatitis (AD. The current literature on factors influencing sick leave is mostly derived from other chronic inflammatory diseases. This study aimed to determine the prevalence of sick leave due to AD and to identify influencing factors. Methods: A cross-sectional study was carried out in adult patients with AD. Outcome measures: sick leave during the two-week and one-year periods, socio-demographic characteristics, disease severity, quality of life and socio-occupational factors. Logistic regression analyses were used to determine influencing factors on sick leave over the two-week period. Results: In total, 253 patients were included; 12% of the patients had to take sick leave in the last two weeks due to AD and 42% in the past year. A higher level of symptom interference (OR 1.26; 95% CI 1.13–1.40 or perfectionism/diligence (OR 0.90; 95% CI 0.83–0.96 may respectively increase or decrease the number of sick leave days. Conclusion: Sick leave in patients with AD is a common problem and symptom interference and perfectionism/diligence appeared to influence it. Novel approaches are needed to deal with symptoms at work or school to reduce the amount of sick leave due to AD.

    Full Text Available Legundi (Vitex trifolia L. is one of Indonesia’s traditional crops that have not been studied and developed into fitofarmaka. Legundi leaves can be used for therapy in asthmatics with optimum level. Therefore it is necessary for optimization of harvesting Legundi leaves which includes time and degree of maturation of the leaves. Harvesting time optimization by means of harvesting the leaves at the different times i.e. morning, noon, and evening, while the leaf maturation level optimization by way of harvesting leaves numbered one through five of the youngest end, then the time of harvesting and leaves that provide optimum levels of viteksikarpin were assigned. Measurements of viteksikarpin assigned using TLCdensitometry then analyzed using Wincats software and Microsoft Office Excel 2007. The highest viteksikarpin levels in Legundi leaves harvested in the afternoon, then during the day, and the lowest in the morning. The highest viteksikarpin levels of Legundi leaves were on second leaf, first leaf, third leaf, fourth leaf, and the lowest on fifth leaf. Optimum levels of viteksikarpin in Legundi leaves was harvested in the afternoon by picking the first until the third leaf.

    2009-01-01

    To describe the consequences of long-term sick leave (>28 days) on working situation, health and lifestyle among employees from the public sector in Sweden. Employees in four county councils and two municipalities on long term sick leave on 1 November 2005 (n = 1,128) answered a questionnaire in February 2006. The response rate was 71.7%. Eighty seven per cent were still on sick leave when the questionnaire was answered: 54% part time and 33% full time. Reporting positive consequences was rare but reporting negative consequences, such as effects on the development of salary, the possibilities of pursuing a career or to change to another job were common. Sick leave seemed to lead to a considerable loss of zest for work, even if the respondents were back in work full time. Regardless of the negative consequences at work, 92% of those on part-time sick leave believed that the part-time sick leave was good for them even if many thought it had negative consequences for employer and colleagues. Long-term sick leave has negative consequences for the individual in work situations, even for those back at work full time. The development of salary and career seem to be most affected. The attitude towards part-time sick leave was positive and this result indicates that there is a potential for an increased degree of partial return to work in the group of people on long-term sick leave.

  1. Parental leave for residents and pediatric training programs.

    Science.gov (United States)

    2013-02-01

    The American Academy of Pediatrics (AAP) is committed to the development of rational, equitable, and effective parental leave policies that are sensitive to the needs of pediatric residents, families, and developing infants and that enable parents to spend adequate and good-quality time with their young children. It is important for each residency program to have a policy for parental leave that is written, that is accessible to residents, and that clearly delineates program practices regarding parental leave. At a minimum, a parental leave policy for residents and fellows should conform legally with the Family Medical Leave Act as well as with respective state laws and should meet institutional requirements of the Accreditation Council for Graduate Medical Education for accredited programs. Policies should be well formulated and communicated in a culturally sensitive manner. The AAP advocates for extension of benefits consistent with the Family Medical Leave Act to all residents and interns beginning at the time that pediatric residency training begins. The AAP recommends that regardless of gender, residents who become parents should be guaranteed 6 to 8 weeks, at a minimum, of parental leave with pay after the infant's birth. In addition, in conformance with federal law, the resident should be allowed to extend the leave time when necessary by using paid vacation time or leave without pay. Coparenting, adopting, or fostering of a child should entitle the resident, regardless of gender, to the same amount of paid leave (6-8 weeks) as a person who takes maternity/paternity leave. Flexibility, creativity, and advanced planning are necessary to arrange schedules that optimize resident education and experience, cultivate equity in sharing workloads, and protect pregnant residents from overly strenuous work experiences at critical times of their pregnancies.

  2. Uranium: do leave it in the ground!

    International Nuclear Information System (INIS)

    Bunyard, P.

    1990-01-01

    A previous author has argued that it would be best in the long run to consume uranium as much as possible in reactors rather than leave it in the ground in order to save the earth and generations into the far distant future from the evils of radiation. The argument is based on a comparison between the radioactive decay processes of fissioned uranium and uranium left in the earth to decay in its own time. It can be shown that from 300 days after reactor shut down onwards, the spent fuel will generate barely 1% of the radioactive energy that it would were it left untouched in the ground. Counter arguments are presented based largely on the risks to human health and life presented by uranium mining and disasters at nuclear plants such as that at Chernobyl. Illustrations are given of the suffering of people living near uranium mines arising from soil contamination by uranium tailings; the widespread radioactive contamination of the surrounding area and increased cancer mortality rates due to the Chernobyl accident are described. Finally, it is pointed out that uranium serves as a radioactive heat source in the gigantic recycling of rocks and the regeneration of the planet. All these arguments lead to the conclusion that uranium is best left in the earth. (UK)

    Olive leaves extract (OLE) was evaluated as green corrosion inhibitor for stainless steel grade 316L (SS316L) in several media using scanning electron microscope (SEM), electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. The Fourier Transform Infrared (FTIR) spectroscopy results reveals several active compound indicated by O-H stretch, C=O stretch, C-OH stretch and C-N stretch which can be attributed to oleuropein and hydroxtyrosol acting as the main inhibiting sources for corrosion. The results obtained also show the inhibition efficiency of OLE increase with the increase of OLE concentration. Through its inhibitive action elucidate from the electrochemical analysis, the extract was found to act as a mixed type inhibitor. Micrographs by SEM showed that the surface of steel which has been coated with 0% and 20% of OLE coating extract possess a lot of pin holes or pores while the steel with 10% of OLE coating extract shows the surface has multiple cracks. This study clearly shows the efficiency of OLE as anticorrosion coating for control of stainless steel in marine application.

    Full Text Available Breast cancer is the leading cause of cancer deaths among females in Malaysia. Ocimum tenuiflorum L., (O. tenuiflorum commonly known as ruku in Malaysia, is usually cultivated as a garden ornamental plant because of its small purplish and some yellowish flower. The specific objective of this research is to investigate the anticancer of O. tenuiflorum against human breast cancer cell lines (MCF-7 and MDA-MB-231 and human fibroblast cell line (HS-27. In addition, another objective is to determine the mineral and heavy metal determination of O. tenuiflorum. O. tenuiflorum exhibited anticancer activity against MCF-7 (a hormone-dependent breast cancer cell line. The viability of MCF-7 cells decreased significantly after treatment with various concentrations of methanolic plant extracts (25 and 100 μg/mL, as shown via 3-(4,5-dimethylthiazol-2-yl2,5-diphenyltetrazolium bromide (MTT assay. The crude extracts show the lower IC50 (less than 100 μg/mL value against the cancer cell lines and show no effect on HS-27. The high content of calcium in the leaves of O. tenuiflorum may play a role in decreasing the risk of certain cancer. The concentrations of heavy metals (Pb and As detected in O. tenuiflorum are safe for consumption.

    Energetic characterization of biomass allows for assessing its energy potential for application in different conversion processes into energy. The objective of this study is to physicochemically characterize pineapple crown leaves (PC) for their application in energy conversion processes. PC was characterized according to ASTM E871-82, E1755-01, and E873-82 for determination of moisture, ash, and volatile matter, respectively; the fixed carbon was calculated by difference. Higher heating value was determined by ASTM E711-87 and ash chemical composition was determined by XRF. The thermogravimetric and FTIR analyses were performed to evaluate the thermal decomposition and identify the main functional groups of biomass. PC has potential for application in thermochemical processes, showing high volatile matter (89.5%), bulk density (420.8 kg/m(3)), and higher heating value (18.9 MJ/kg). The results show its energy potential justifying application of this agricultural waste into energy conversion processes, implementing sustainability in the production, and reducing the environmental liabilities caused by its disposal.

  9. Left ventricular filling rate change as an earlier indicator than ejection fraction of chemotherapeutic cardiotoxicity in cancer paptents' nuclear medicine MUGA scans

    International Nuclear Information System (INIS)

    Miko, T.G.

    2004-01-01

    According to Wang Siegel has long suggested that an earlier indicator of damage to the hearts of cancer patients undergoing potentially cardiotoxic chemotherapy could be change in the left ventricular filling rate (LVFT) rather than dependence on the left ventricular ejection fraction (LVEF) as a measure for when to discontinue chemotherapy. Currently ejection fraction obtained by performing the nuclear medicine MUGA scan is the gold standard for determining further treatment of patients with these cardiotoxic agents. We are seeking to see if changes in filling rate (LVFR) are an earlier indicator of cardiotoxicity by performing a retrospective analysis of MUGA scans performed at our facility pre- and post-chemotherapy and performing a statistical analysis of changes in ejection fraction us filling rate in patients known to have cardiotoxic changes due to chemotherapy.

    The study aimed to describe the age distribution of breast cancer diagnosis among Chinese females for comparison with the United States and the European Union, and provide evidence for the screening target population in China. Median age was estimated from hospital databases from 7 tertiary hospitals in China. Population-based data in China, United States and European Union was extracted from the National Central Cancer Registry, SEER program and GLOBOCAN 2008, respectively. Age-standardized distribution of breast cancer at diagnosis in the 3 areas was estimated based on the World Standard Population 2000. The median age of breast cancer at diagnosis was around 50 in China, nearly 10 years earlier than United States and European Union. The diagnosis age in China did not vary between subgroups of calendar year, region and pathological characteristics. With adjustment for population structure, median age of breast cancer at diagnosis was 50~54 in China, but 55~59 in United States and European Union. The median diagnosis age of female breast cancer is much earlier in China than in the United States and the European Union pointing to racial differences in genetics and lifestyle. Screening programs should start at an earlier age for Chinese women and age disparities between Chinese and Western women warrant further studies.

    Standardization of postoperative care has been shown to decrease postoperative length of stay. In June 2009, we standardized postoperative care for all gastrectomies at our institution. Four years' worth of total gastrectomies (2 years prior to standardization and 2 years after standardization) were reviewed to determine the effect of standardization on postoperative care, length of stay, complications, and readmissions. Between June 2007 and July 2011, 99 patients underwent curative intent open total gastrectomy: 51 patients prior to standardization, and 48 patients poststandardization. Patients were predominantly male (70%); median age was 63; and median body mass index was 26. Standardization of postoperative care was associated with a decrease in median time to beginning both clear liquids and a postgastrectomy diet, earlier removal of epidural catheters, earlier use of oral pain medication, less time receiving intravenous fluids, and decreased length of stay (all P Care Center, or readmission.

    Metabolic processes in primary leaves of bean plants (Phaseolus vulgaris) were altered by ozone stress. Decreases in levels of ribonucleic acid (RNA) and protein, and increases in ribonuclease (RNase) and free amine groups were associated with visible oxidant injury to the leaves. It appears that some air pollution injury to plants may result from changes in metabolic processes. 23 references, 5 figures, 2 tables.

  1. The impact of paternity leave on fathers' future earnings.

    Science.gov (United States)

    Rege, Mari; Solli, Ingeborg F

    2013-12-01

    Using Norwegian registry data, we investigate the effect of paternity leave on fathers' long-term earnings. If the paternity leave increased long-term father involvement, then we should expect a reduction in fathers' long-term earnings as they shift time and effort from market to home production. For identification, we use the Norwegian introduction of a paternity-leave quota in 1993, reserving four weeks of the total of 42 weeks of paid parental leave exclusively for the father. The introduction of the paternity-leave quota led to a sharp increase in rates of leave-taking for fathers. We estimate a difference-in-differences model that exploits differences in fathers' exposure to the paternity-leave quota by the child's age and year of observation. Our analysis suggests that four weeks of paternity leave during the child's first year decreases fathers' future earnings, an effect that persists through our last point of observation, when the child is 5 years old. A battery of robustness tests supports our results.

    Tobacco farmers are routinely exposed to complex mixtures of inorganic and organic chemicals present in tobacco leaves. In this study, we examined the genotoxicity of tobacco leaves in the snail Helix aspersa as a measure of the risk to human health. DNA damage was evaluated using the micronucleus test and the Comet assay and the concentration of cytochrome P450 enzymes was estimated. Two groups of snails were studied: one fed on tobacco leaves and one fed on lettuce (Lactuca sativa L) leaves (control group). All of the snails received leaves (tobacco and lettuce leaves were the only food provided) and water ad libitum. Hemolymph cells were collected after 0, 24, 48 and 72 h. The Comet assay and micronucleus test showed that exposure to tobacco leaves for different periods of time caused significant DNA damage. Inhibition of cytochrome P450 enzymes occurred only in the tobacco group. Chemical analysis indicated the presence of the alkaloid nicotine, coumarins, saponins, flavonoids and various metals. These results show that tobacco leaves are genotoxic in H. aspersa and inhibit cytochrome P450 activity, probably through the action of the complex chemical mixture present in the plant.

    2013-01-01

    Flavonols and hydroxycinnamic acids are known to contribute to plant resistance against pathogens, but there are few reports on the implication of flavonols in the resistance of grapevine against Plasmopara viticola, and none on the involvement of hydroxycinnamic acids. In order to analyze the effect of flavonols on P. viticola infection, variable amounts of flavonols were induced by different light conditions in otherwise phenologically identical leaves. Differences in content of leaf hydroxycinnamic acids were induced at the same time. A non-invasive monitoring of flavonols and hydroxycinnamic acids was performed with Dualex leaf-clip optical sensors. Whatever the light condition, there were no significant changes in flavonol or in hydroxycinnamic acid contents for control and inoculated leaves during the development of P. viticola until 6 days after inoculation. The violet-blue autofluorescence of stilbenes, the main phytoalexins of grapevine that accumulate in inoculated leaves, was used as an indicator of infection by P. viticola. The implication of leaf constitutive flavonols and hydroxycinnamic acids in the defence of Vitis vinifera against P. viticola could be investigated in vivo thanks to this indicator. The increase in stilbene violet-blue autofluorescence started earlier for leaves with low flavonol content than for leaves with higher content, suggesting that constitutive flavonols are able to slow down the infection by P. viticola. On the contrary, constitutive hydroxycinnamic acids did not seem to play a role in defence against P. viticola. The non-destructive nature of the methods used alleviates the major problem of destructive experiments: the large variability in leaf phenolic contents.

    The 89 Sr was added to the tea tree-soil system by different ways. The 89 Sr in the system through the over-ground part of tea tree, was much more than that through soil. The 89 Sr concentration in older leaves was higher than in shoot for a definite treatment. The accumulation elimination law of 89 Sr in leaves varied with the treatments. For the treatment through the over-ground part, the 89 Sr concentration in older leaves and shoot was monotonously decreased with time increasing. But for the treatment through soil the 89 Sr concentration in shoot was increased to reach a peak value, and then decreased slowly; while the 89 Sr concentration in older leaves increased quickly in a period, then increased slowly to attain a saturated value. In addition, the concentration factor of 89 Sr in older leaves and shoot were determined

    Leoni van der Vaart

    2015-03-01

    Full Text Available Employability emerged as a “new psychological contract” that may have beneficial effects on both individual and organisational outcomes. The study set out to investigate the relationship between perceived employability and employee well-being on the one hand and perceived employability and employees’ intention to leave on the other. The role of the state of the psychological contract, in terms of retaining employable employees while improving their well-being, was also investigated. Cross-sectional data were obtained from employees representing various organisations (N = 246. Contrary to expectations, structural equation modelling (SEM indicated no significant relationship between perceived employability and well-being. Perceived employability was a significant predictor of employees’ intention to leave the organisation. Results also indicated that the state of the psychological contract does not moderate the relationship between perceived employability and employee well-being and their intention to leave, respectively. The study stresses the importance of fulfilling promises made to employees ensuring that promises are fair and continuing to fulfil promises. The importance of interventions on individual-level, to enhance well-being in the workplace, is also emphasised.

    Saddichha, Sahoo; Saxena, Mukul Kumar

    2010-01-01

    Background: Most emergencies in Goa arise due to road traffic accidents and drowning, which have been compounded by the rise in number of recorded accidents in 2007 to be above 4000. It is believed that 11 people meet with an accident on Goa's roads every day and this is expected to rise by 10% by next year. Similar is the case with drownings and other medical emergencies. We therefore aimed to conduct a cross-sectional survey of medical emergencies and identify various types of emergencies presenting to emergency departments. Materials and Methods: Using a stratified random sampling design, all emergencies presenting to the three government hospitals in Goa, which handle 90% of all emergencies currently, were studied on specially designed data sheets in order to collect data. Emergency medical technicians (ETs) were placed in the Casualty Ward of the medical colleges and they recorded all emergencies on the data sheet. The collected data were then analyzed for stratification and mapping of emergencies. Results: GMC Hospital attended to majority of emergencies (62%), which were mainly of the nature of accidents or assaults (17%) and fever related (17%). Most emergencies were noncritical and about 1% expired. Maximum emergencies also presented from Salcette and Bardez, and occurred among young males in the age group of 19-45 years. Males were also more prone to accidents while females had pregnancies as emergencies. Conclusion: Potential emergency services need to target young males with higher concentrations required in Salcette in South Goa and Bardez in North Goa. PMID:20606921

Grape berries, as ‘sink organs,’ rely on the use of available carbohydrate resources produced by photosynthesis to support their development and composition. A high throughput two-dimensional gel electrophoresis (2-DE was conducted on muscadine (Vitis rotundifolia grape leaf proteins to document complexity in their composition and to determine protein identity and function for enhancing photosynthetic efficiency of muscadine grape. 2-DE resolved muscadine leaf proteins into >258 polypeptides with pIs between 3.5 and 8.0 and molecular weight between 12,000 to 15,0000 Daltons. The consistently expressed proteins were excised and subjected to sequencing. Homology search of protein sequences showed 84% identity with Viridi plantae database. Identity of some of these proteins included RuBisCO, glutamine synthetase, pathogenesis-related protein, glyoxisomal malate dehydrogenase, ribonucleoprotein, chloroplast precursor, oxygen evolving enhancer protein. Comparative analysis of 10 muscadine cultivars showed quantitative differences in expression of 39 polypeptides among these genotypes. The results suggested that the polypeptide composition of muscadine grape leaf is complex, and polypeptide number and amount vary widely among muscadine genotypes, and these variations may be responsible for differences in their physiology, berry and stress tolerance characteristics.Keywords: grapevine, leaves, muscadine, proteins, sequencing, 2-DE

    Postpartum depression affects a substantial proportion of new mothers in the United States. Although most employed women return to paid work after birth, the association between duration of maternity leave and postpartum depression is unclear. We therefore aimed to explore this relationship among mothers in the United States. Data included 177 mothers from a national survey who had returned to work full time after having a baby. Multivariable logistic regression was used to explore the independent association between duration of maternity leave and experiencing of postpartum depressive symptoms in the 2 weeks preceding the postpartum survey completion. Overall, duration of maternity leave was not significantly associated with experiencing postpartum depression symptoms (odds ratio [OR], 0.90; 95% confidence interval [CI], 0.80-1.01). This effect, however, varied by duration of maternity leave. Among women who took maternity leaves of 12 weeks or less, every additional week of leave was associated with a lesser odds of experiencing postpartum depressive symptoms (OR, 0.58; 95% CI, 0.40-0.84). Among women who took maternity leaves longer than 12 weeks, leave duration was not associated with postpartum depression symptoms (OR, 0.97; 95% CI, 0.73-1.29). Maternity leaves equaling 12 weeks or less may contribute additional risk for postpartum depressive symptoms, possibly because mothers are juggling employment alongside of important physical and emotional changes during this period. This association underscores the importance of ensuring that mothers have at least 12 weeks of leave from full-time employment after the birth of a baby.

    To identify parental leave policies and availability of support systems for new parents employed by children's hospitals and compare these benefits with those offered by Fortune 500 companies. Telephone or facsimile survey of all (n=118) children's hospitals and pediatric medical centers in the National Association of Children's Hospitals and Related Institutions 1995 Directory of Members, and 118 geographically matched Fortune 500 companies. Policies for maternity and paternity leave, adoption benefits, and support services for new parents were compared. Ninety-four children's hospitals (80%) and 82 Fortune 500 companies (69%) responded to the survey. No difference in duration of maternity (P>.30) or paternity (P=.12) leave was found. Sixty-two companies (77%) classified maternity leave as short-term disability while 47 hospitals (50%) classified it as sick time (Pleave as short-term disability generally gives better benefits to employees with short duration of service, whereas classifying maternity leave as sick time usually favors employees with longer employment. Companies provided more financial support for adoption expenses (Ppaid or unpaid leave for adoption (P=.14). Hospitals provided more on-site day care (69% vs 42%; Pparental leave benefits than Fortune 500 companies; however, they offer better support systems for parents returning to work after the birth of a child.

  14. Phloem unloading in developing leaves of sugar beet

    Physiological and transport data support a symplastic pathway for phloem unloading in developing leaves of sugar beet (Beta vulgaris L. Klein E, multigerm). The sulfhydryl inhibitor parachloromercuribenzene sulfonic acid (PCMBS) inhibited uptake of [ 14 C]-sucrose added to the free space of developing leaves, but did not affect import of [ 14 C]-sucrose during steady-state 14 CO 2 labeling of a source leaf. The passively-transported xenobiotic sugar, [ 14 C]-L-glucose did not readily enter mesophyll cells when supplied through the cut end of the petiole of a sink leaf as determined by whole leaf autoradiography. In contrast, [ 14 C]-L-glucose translocated through the phloem from a mature leaf, rapidly entered mesophyll cells, and was evenly distributed between mesophyll and veins. Autoradiographs of developing leaves following a pulse of 14 CO 2 to a source leaf revealed rapid passage of phloem translocated into progressively higher order veins as the leaf developed. Entry into V order veins occurred during the last stage of import through the phloem. Import into developing leaves was inhibited by glyphosate (N-phosphomethylglycine), a herbicide which inhibits the aromatic amino acid pathway and hence protein synthesis. Glyphosate also stopped net starch accumulation in sprayed mature leaves, but did not affect export of carbon from treated leaves during the time period that import into developed leaves was inhibited

    To describe and compare registered nurse (RN) and licensed practical nurse (LPN) emotional exhaustion, intention to leave and reasons for leaving. Different skill mix/care delivery models are being used to address nurse shortages and rising health-care costs. Skill mix may include RNs and LPNs. More LPNs are being employed in areas, such as acute care, that have been previously staffed by all RNs. Little is known about nurse outcomes since the introduction of LPNs to acute care settings. This study was a cross-sectional correlational design. A stratified, random sample of acute care nurses completed surveys via Fluidsurveys. The survey was modelled after the RN4CAST nursing workforce survey. For both groups of nurses higher levels of emotional exhaustion were associated with intention to leave and workload was the most frequent reason cited for intention to leave. More RNs than LPNs cited career advancement as a reason to leave, and more LPNs than RNs identified poor salary as a reason to leave. Emotional exhaustion is linked to intention to leave health care. Nurse managers should address work environment factors associated with turnover intentions, such as professional development opportunities and shared decision-making. © 2015 John Wiley & Sons Ltd.

    In this study, thin-layer drying characteristics of some herbal leaves, mainly nettle and mint leaves, are investigated experimentally in a convective drier. Effects of the drying air parameters including temperature, velocity and relative humidity on the total drying time are determined. Initially, sorption isotherms of the dried leaves are determined for different temperatures and equilibrium relative humidity (e.r.h.). Experiments are conducted for air temperatures at 35, 45 and 55 deg. C, velocities at 0.2, 0.4 and 0.6 m/s and, relative humidity values at 40%, 55% and 70%. In the ranges that covered, the values of the moisture diffusivity D eff are obtained between 1.744 x 10 -9 and 4.992 x 10 -9 m 2 /s for nettle leaves and 1.975 x 10 -9 and 6.172 x 10 -9 m 2 /s for mint leaves from the Fick's diffusion model. Using D eff , the value of E a is determined assuming the Arrhenius-type temperature relationship, which varies from 79.873 to 109.003 kJ/mol for nettle leaves and 66.873 to 71.987 kJ/mol for mint leaves

    Development of vegetative and floral buds was found to be a key factor in establishing the way carbon is distributed among growing leaves and fruits in Phaseolus vulgaris L. plants. Leaves emerged principally during a period 14 to 32 days after planting while flowers were produced during a 10- to 12-day period near the end of leaf emergence. Timing of anthesis established the sigmoidal time course for dry weight accumulated by the composite of all fruits on the plant. During the first 12 days following anthesis, fruit growth mainly consisted of elongation and dry weight accumulation by the pod wall. Thereafter, seed dry weight increased for about 1 week, decreased markedly for several days, and then increased again over the next 2 weeks. Accumulation of imported carbon in individual seeds, measured by steady-state labeling, confirmed the time course for dry weight accumulation observed during seed development. Seed respiration rate initially increased rapidly along with dry weight and then remained nearly steady until seed maturation. A number of developmental events described in the literature coincided with the different phases of diauxic growth. The results demonstrated the feasibility of relating current rates of carbon import in individual seeds measured with tracer 14 C to the rates of conversion of imported sucrose and use of the products for specific developmental processes. The resulting data are useful for evaluating the roles of conversion and utilization of imported sucrose in regulating import by developing seeds

    The fossil record of alder (Alnus) is well known in the Cenozoic deposits throughout the northern hemisphere, based on numerous reports of the distinctive pollen, cone-like infructescences, staminate inflorescences, and leaves. However, our understanding of the systematic position of these fossils relative to the modern phylogeny of the genus has been limited because most fossils were described from only one organ. We examined well-preserved leaves and associated fruiting and staminate catkins from the middle Eocene, Clarno Formation, Oregon, USA by stereomicroscopy. In situ and dispersed pollen were cleaned with HF and acetolized for light and scanning electron microscopy. We reconstructed a new extinct species based on multiple organs and discuss significant phytogeographic and phylogenetic implications for Alnus. Alnus clarnoensis sp. nov. is described based on serrate leaves with 1-4 small teeth between each primary tooth, associated cone-like fruiting catkins with fruits in situ, and associated slender pollen catkins bearing in situ 3- to 6-pored pollen with arci between the pores. Combined investigations of each organ indicate that they probably derive from the same species and can be confidently attributed to subgenus Alnus Furlow based on leaf architecture and pollen pore number frequency. The Clarno fossils are most similar to the extant North American species of subgenus Alnus rather than to those from Asia and Europe, indicating that this modern subgenus was already distinct by the middle Eocene and that the intercontinental migration likely occurred earlier. © 2014 Botanical Society of America, Inc.

    Research on the biosynthesis of abscisic acid (ABA) has focused primarily on two pathways: (a) the direct pathway from farnesyl pyrophosphate, and (b) the indirect pathway involving a carotenoid precursor. The authors have investigated which biosynthetic pathway is operating in turgid and stressed Xanthium leaves, and in stressed Xanthium roots using long-term incubations in 18 O 2 . It was found that in stressed leaves three atoms of 18 O from 18 O 2 are incorporated into the ABA molecule, and that the amount of 18 O incorporated increases with time. One 18 O atom is incorporated rapidly into the carboxyl group of ABA, whereas the other two atoms are very slowly incorporated into the ring oxygens. The fourth oxygen atom in the carboxyl group of ABA is derived from water. ABA from stressed roots of Xanthium incubated in 18 O 2 shows a labeling pattern similar to that of ABA in stressed leaves, but with incorporation of more 18 O into the tertiary hydroxyl group at C-1' after 6 and 12 hours than found in ABA from stressed leaves. It is proposed that the precursors to stress-induced ABA are xanthophylls, and that a xanthophyll lacking an oxygen function at C-6 plays a crucial role in ABA biosynthesis in Xanthium roots. In turgid Xanthium leaves, 18 O is incorporated into ABA to a much lesser extent that it is in stressed leaves, whereas exogenously applied 14 C-ABA is completely catabolized within 48 hours. This suggests that ABA in turgid leaves is either (a) made via a biosynthetic pathway which is different from the one in stressed leaves, or (b) has a half-life on the order of days as compared with a half-life of 15.5 hours in water-stressed Xanthium leaves. Phaseic acid showed a labeling pattern similar to that of ABA, but with an additional 18 O incorporated during 8'-hydroxylation of ABA to phaseic acid

    Resveratrol is an important stilbene that benefits human health. However, it is only distributed in a few species including grape and is very expensive. At present, grape has been an important source resveratrol. However, the details are scarce on resveratrol distribution in different Vitis species or cultivars. The composition and content of resveratrols were investigated by HPLC for assessing genotypic variation in berry skins and leaves of 75 grape cultivars, belonging to 3 species and 7 interspecific hybrids. Trans-resveratrol, cis-piceid and trans-piceid were detected in berry skins and leaves, but cis-resveratrol was not. Resveratrol content largely varied with genetic background as well as usage. In most cultivars, total resveratrol including the above three compounds was higher in berry skins than leaves. In berry skins of most cultivars and leaves of almost all cultivars, cis-piceid was the most abundant resveratrol; trans-resveratrol and trans-piceid were minor components. Some specific cultivars were found with extremely high levels of trans-resveratrol, cis- piceid, trans-piceid or total resveratrols in berry skins or leaves. In skins and leaves, rootstock cultivars had a higher content of total resveratrols, and the cultivated European type cultivars and their hybrids with V. labrusca had relatively low totals. There were no significant correlations of the amounts of total resveratrols or any individual resveratrol between berry skins and leaves. All 75 cultivars can be divided into four groups based on the composition of resveratrols and their concentration by principal component analysis. Resveratrol content of grape berries and leaves varied largely with their genetic background and usage. Rootstock cultivars had a higher content of total resveratrols than the other germplasm. Total resveratrols were lower in leaves than berry skins in most cultivars. Cis-piceid was the most abundant resveratrol in most cultivars, and trans-res and trans-pd were

    RESEARCH ON THE BIOSYNTHESIS OF ABSCISIC ACID (ABA) HAS FOCUSED PRIMARILY ON TWO PATHWAYS: (a) the direct pathway from farnesyl pyrophosphate, and (b) the indirect pathway involving a carotenoid precursor. We have investigated which biosynthetic pathway is operating in turgid and stressed Xanthium leaves, and in stressed Xanthium roots using long-term incubations in (18)O(2). It was found that in stressed leaves three atoms of (18)O from (18)O(2) are incorporated into the ABA molecule, and that the amount of (18)O incorporated increases with time. One (18)O atom is incorporated rapidly into the carboxyl group of ABA, whereas the other two atoms are very slowly incorporated into the ring oxygens.

It is proposed that the precursors to stress-induced ABA are xanthophylls, and that a xanthophyll lacking an oxygen function at C-6 (carotenoid numbering scheme) plays a crucial role in ABA biosynthesis in Xanthium roots. In turgid Xanthium leaves, (18)O is incorporated into ABA to a much lesser extent than it is in stressed leaves, whereas exogenously applied (14)C-ABA is completely catabolized within 48 hours.

    The organization for dealing with radiation emergencies in France is complex and centralized. It consists of the Radiation Security Council with participants from the Premier Ministre and the Ministers of Interior, Industry, Health, and Defense. A permanent general secretary for radiation security coordinates the work of the various departments. Planning for nuclear power emergencies is divided between on-site, in which organization and intervention are the responsibilities of the manager of the plant, and off-site, in which organization and intervention are the responsibility of the regional governor. Both on-site and off-site planning have models integrated into a special code of practice called the radiation emergency organization

    Absences from work have considerable social and economic impact. In the education sector, the phenomenon is particularly worrying since teacher sick leave has an impact on the overall performance of the education system. Yet, available data are scarce. In April-June 2013, 2653 teachers responded to a population-based postal survey on their quality of life (enquête Qualité de vie des enseignants, MGEN Foundation/Ministry of education, response rate 53 %). Besides questions on work environment and health, teachers were asked to describe their eventual sick leave(s) since the beginning of the school year: duration, type and medical reasons. Self-reported information was reinforced by administrative data from ministerial databases and weighted to be extrapolated to all French teachers. Tobit models adjusted for individual factors of a private nature were used to investigate different occupational risk factors of teacher sick leave, taking into account both the estimated effect on the probability of sick leave and the length of it. More than one in three teachers (36 %) reported having had at least one day of sick leave since the beginning of the school year. Respiratory/ENT diseases were the leading reason for sick leave (37 %). However, and because sick leave duration depended on the underlying health problem, such diseases came in third place among justifications of sick leave days (14 %), far behind musculoskeletal problems (27 %) and neurological and psychological disorders (25 %). Tobit models suggested that some occupational factors significantly associated with the risk of sick leave may represent promising preventive targets, including high psychological demand, workplace violence and unfavorable socio-environmental context. Our study provides objective evidence about the issue of sick leave among French teachers, highlighting the usefulness of implementing actions to minimize its weight. To this end, the study findings point-out the importance of

    Detached and attached, inoculated and noninoculated, ozone-injured and noninjured leaves from the lower, middle, and terminal regions of plants of geranium cultivars Enchantress and White Mountain were observed for infection by Botrytis cinerea. Previous exposure to ozone did not appreciably influence the susceptibility of leaves of either geranium cultivar to infection by B. cinerea, unless there was visible ozone injury. Ozone-injured, necrotic tissues on older attached and detached geranium leaves of both cultivars served as infection courts for B. cinerea. 14 references, 1 table.

    Ontology is a semantic analysis and calculation model, which has been applied to many subjects. Ontology similarity calculation and ontology mapping are employed as machine learning approaches. The purpose of this paper is to study the leave-two-out stability of ontology learning algorithm. Several leave-two-out stabilities are defined in ontology learning setting and the relationship among these stabilities are presented. Furthermore, the results manifested reveal that leave-two-out stability is a sufficient and necessary condition for ontology learning algorithm.

    To prevent contamination of fresh produce with enteric pathogens, more insight into mechanisms that may influence the association of these pathogens with fresh produce is needed. In this study, Escherichia coli O157:H7 and Salmonella were chosen as model pathogens, and fresh cut iceberg lettuce was chosen as a model fresh produce type. The morphological structure of iceberg lettuce leaves (stomatal density and length of cell margins per leaf area) was quantified by means of leaf peels and light microscopy of leaves at different stages of development (outer, middle, and inner leaves of the crop) on both leaf sides (abaxial and adxial) and in three leaf regions (top, center, and bottom). The morphology of the top region of the leaves was distinctly different from that of the center and base, with a significantly higher stomatal density (up to five times more stomata), different cell shape, and longer cell margins (two to three times longer). Morphological differences between the same regions of the leaves at different stages of development were smaller or nonsignificant. An attachment assay with two attenuated E. coli O157:H7 strains (84-24h11-GFP and BRMSID 188 GFP) and two Salmonella strains (serovars Thompson and Typhimurium) was performed on different regions of the middle leaves. Our results confirmed earlier reports that these pathogens have a higher affinity for the base of the lettuce leaf than the top. Differences of up to 2.12 log CFU/g were seen ( E. coli O157:H7 86-24h11-GFP). Intermediate attachment occurred in the central region. The higher incidence of preferential bacterial attachment sites such as stomata and cell margins or grooves could not explain the differences observed in the association of the tested pathogens with different regions of iceberg lettuce leaves.

    In recent years, emerging diseases were defined as being infectious, acquiring high incidence, often suddenly, or being a threat or an unexpected phenomenon. This study discusses the hallmarks of emerging diseases, describing the existence of noninfectious emerging diseases, and elaborating on the advantages of defining noninfectious diseases as emerging ones. From the discussion of various mental health disorders, nutritional deficiencies, external injuries and violence outcomes, work injuries and occupational health, and diseases due to environmental factors, the conclusion is drawn that a wide variety of noninfectious diseases can be defined as emergent. Noninfectious emerging diseases need to be identified in order to improve their control and management. A new definition of "emergent disease" is proposed, one that emphasizes the pathways of emergence and conceptual traits, rather than descriptive features.

  18. The unintended consequences of maternity leaves: How agency interventions mitigate the negative effects of longer legislated maternity leaves.

    2018-06-07

    To support women in the workplace, longer legislated maternity leaves have been encouraged in Scandinavian countries and recently in Canada. Yet, past research shows that longer legislated maternity leaves (i.e., 1 year and longer) may unintentionally harm women's career progress. To address this issue, we first sought to identify one potential mechanism underlying negative effects of longer legislated maternity leaves: others' lower perceptions of women's agency. Second, we utilize this knowledge to test interventions that boost others' perceptions of women's agency and thus mitigate negative effects of longer legislated maternity leaves. We test our hypotheses in three studies in the context of Canadian maternity leave policies. Specifically, in Study 1, we found that others' lower perceptions of women's agency mediated the negative effects of a longer legislated maternity leave, that is, 1 year (vs. shorter, i.e., 1 month maternity leave) on job commitment. In Study 2, we found that providing information about a woman's agency mitigates the unintended negative effects of a longer legislated maternity leave on job commitment and hireability. In Study 3, we showed that use of a corporate program that enables women to stay in touch with the workplace while on maternity leave (compared to conditions in which no such program was offered; a program was offered but not used by the applicant; and the program was offered, but there was no information about its usage by the applicant) enhances agency perceptions and perceptions of job commitment and hireability. Implications for theory and practice are discussed. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

    Although the menace of nuclear war still persists, the focus in national emergency preparedness in Finland is presently on emergencies involving nuclear installations. The nuclear power plants, nuclear submarines and other installations in the former USSR are a major reason for this. In this article the main features and organization of emergency preparedness in Finland are described. (orig.)

    Sports neurology is an emerging area of subspecialty. Neurologists and non-neurologists evaluating and managing individuals participating in sports will encounter emergencies that directly or indirectly involve the nervous system. Since the primary specialty of sports medicine physicians and other practitioners involved in the delivery of medical care to athletes in emergency situations varies significantly, experience in recognition and management of neurologic emergencies in sports will vary as well. This article provides a review of information and elements essential to neurologic emergencies in sports for the practicing neurologist, although content may be of benefit to readers of varying background and expertise. Both common neurologic emergencies and less common but noteworthy neurologic emergencies are reviewed in this article. Issues that are fairly unique to sports participation are highlighted in this review. General concepts and principles related to treatment of neurologic emergencies that are often encountered unrelated to sports (eg, recognition and treatment of status epilepticus, increased intracranial pressure) are discussed but are not the focus of this article. Neurologic emergencies can involve any region of the nervous system (eg, brain, spine/spinal cord, peripheral nerves, muscles). In addition to neurologic emergencies that represent direct sports-related neurologic complications, indirect (systemic and generalized) sports-related emergencies with significant neurologic consequences can occur and are also discussed in this article. Neurologists and others involved in the care of athletes should consider neurologic emergencies in sports when planning and providing medical care.

    The aim of this study was to assess whether serology and spirometry and the combination of both can complement culture-based detection for earlier recognition of Pseudomonas aeruginosa infection in children with cystic fibrosis. A 4 year longitudinal prospective study that included 67 Slovenian children with cystic fibrosis with a mean age of 10.5 years was conducted. Serology, spirometry and a scoring system combining serology and spirometry were assessed and compared. Infection was confirmed with isolation of Pseudomonas aeruginosa from respiratory samples. There was a significantly positive correlation between serology and the combination of serology and spirometry and Pseudomonas aeruginosa isolation (P spirometry and Pseudomonas aeruginosa isolation (P spirometry the highest sensitivity (0.90). Both had a high negative predictive value (0.93 and 0.79 respectively). Using serology and the combination of serology and lung function measurement can be beneficial for earlier detection of infection with Pseudomonas aeruginosa in children with cystic fibrosis when done simultaneously with standard culture-based detection from respiratory samples.

    Girls with Turner syndrome are prone to cholesteatoma, a serious suppurative middle ear disease. We aimed to confirm its high prevalence in Turner syndrome, identify risk factors and suggest possible strategies for earlier detection. We reviewed 179 girls with Turner syndrome between 1989 and 2012 to identify cases of cholesteatoma. Seven girls (3.9%) had cholesteatoma (index girls) and each was compared with three age-matched girls without cholesteatoma (comparison girls). All the index girls had either the 45,X or 45,X/46X,i(Xq) karyotypes. Nine ears were initially affected, with three recurrences in two girls. Median age at first cholesteatoma presentation was 11.9 years (range: 7.5-15.2), with otorrhoea for three (range: one to seven) months in all 12 affected ears. Index girls had a significantly higher proportion of previous recurrent acute (p = 0.007) and chronic otitis media (p = 0.008), chronic perforation (p = 0.038) aural polyps (p Turner syndrome. Risk factors include 45,X and 46,XiXq karyotypes; a history of chronic otitis media, tympanic membrane retraction and persistent otorrhoea; and older age. Earlier recognition of ear disease is needed and otoscopy training for paediatricians caring for Turner syndrome patients may be beneficial. ©2014 Foundation Acta Paediatrica.

    Wind-Induced flutter of leaves depends on both wind velocity and the gravity. To study the gravitational effects on the oscillatory behavior of leaves in the wind, a wind tunnel that can be tilted about the center of the test section is created. This unique rotation capability allows systematic investigation of gravitational effects on the fluttering response of leaves. The flow-induced vibration will be studied for three different leaves at several different tilting angles including the wind travels horizontally, vertically downward and vertically upward. In each situation, the long axis of a leaf is placed parallel to the wind direction and its response is studied at different flow speed. Oscillation of the leaf is recorded via high-speed camera at each of setup, and the effect of the gravity on stabilizing or destabilizing the fluttering response is investigated.

    Paid parental leave policies have the potential to strengthen economic supports, reduce family discord, and provide opportunities to empower women (Basile et al., 2016; Niolon et al., 2017). In this article, we present a theory of change and evidence to suggest how paid parental leave may impact intimate partner violence (IPV). In doing so, we present three mechanisms of change (i.e., reduction in financial stress, increase in egalitarian parenting practices, and promotion of child/parent bonding) through which paid parental leave could reduce rates of IPV. We also describe limitations of the current state of knowledge in this area, as well as opportunities for future research. Ultimately, our goal is to facilitate the identification and implementation of approaches that have the potential to reduce violence at the population level. Paid parental leave embodies the potential of policies to change societal-level factors and serve as an important prevention strategy for IPV. Copyright © 2018. Published by Elsevier Inc.

    A study was made in Tashkent, Russia of the dust-retaining power of leaves of several tree species. Investigations were made in a park where these tree species were growing in close proximity, exposed to the effects of dust from the main city street and from the highway passing through the park. Observations on the dust-retaining power of leaves were made mostly during the summer and fall months. The dust-retaining power of leaves of different tree species varied with the dust concentration in the air. In the summer and fall when rains are scarce a steady accumulation of dust was observed on the surface of the leaves. 1 table.

  18. Consequences Paternity Leave on Allocation of Childcare and Domestic Tasks

    Full Text Available One of the main objectives of parental leave policies aimed exclusively at fathers is to promote gender equality in the productive and reproductive spheres. The aim of this study is to examine whether the use of paternity leave fosters greater involvement of fathers in the division of tasks within the reproductive sphere, specifi cally child care and housework. Based on data from the survey, ?Social use of parental leave in Spain, 2012?, we have created multivariate models using ordinary least squares regression. The sample used in the analysis consists of 600 fathers who have had at least one child since 2007. The results suggest that paternity leave does encourage greater involvement by fathers in childcare, but the effect is limited, as it is only found for fathers after the birth of their fi rst child.

  19. The Relationship between Restraints of Trade and Garden Leave

    Full Text Available The purpose of the article is to examine the relationship between a so-called "garden leave" clause and a post-termination restraint of trade clause in employment contracts, in view of the decision in Vodacom (Pty Ltd v Motsa 2016 3 SA 116 (LC. The Labour Court grappled with the question of whether the enforcement of the garden leave provision impacts on the enforcement of a post-termination restraint of trade clause. Enforcement of both these types of clauses may be problematic. It can result in unfairness if an employee ends up being commercially inactive for a long period. The author argues that garden leave has a direct effect on the enforcement of a post- termination restraint of trade clause. Accordingly, a restraint of trade will be enforced only if the employer's proprietary interest requires additional protection beyond what is achieved under the garden leave clause.

  20. Spill sparks reform, leaves lasting scar

    1991-01-01

    Blackened shorelines, oil-soaked birds, and dying sea otters - images that riveted the Exxon Valdez oil spill on the public consciousness - also generated an outcry for action, Notthoff observes. No other spill caught the attention of the American public and prompted public-policy reform at the national, state, and local level like the Exxon Valdez, she says. Within two years of the accident, Congress had dusted off and passed oil-spill legislation that had been deadlocked for 10 years, and seven states had passed new oil-spill laws. The poor record of cleanup following the Exxon Valdez spill is due to the limits of technology, the physical conditions at the time of the accident, and a chronic inability to mobilize people and equipment under the chaotic circumstances that surround a major emergency, Notthoff says. In addition, there also was a failure to enforce existing response plans. Prevention is the best cure, and some of the new laws address this issue, she notes. They also tighten up requirements for response planning and encourage research into improved clean-up technology. What they fail to do Notthoff emphasizes, is seek to reduce tanker traffic by encouraging improved energy efficiency, conservation, and alternative energy technologies
