Partial cutting to develop two-age stands is a relatively new practice in the central Appalachian region, and forest managers need quantitative information in order to evaluate how well it meets management objectives. Typically, this practice leaves a residual overstory of 10 to 40 ft2 per ac of basal area and leads to regeneration of desirable...

This study aimed to understand nursing practice environment characteristics in Istanbul-area hospitals in Turkey, the relationship between these characteristics, nurse burnout levels and nurses' intentions to leave work. A well-known relationship exists in many countries between nursing practice environments and nurse burnout and intention to leave work. However, little is known about the relationship between practice environment characteristics and nursing outcomes in Turkey. This cross-sectional study was conducted among 2592 nurses in 20 Ministry of Health and 29 private hospitals in Istanbul, Turkey. A demographic questionnaire, Practice Environment Scale of the Nursing Work Index and Maslach Burnout Inventory were used for data collection. Almost half of nurses suffered from high-level burnout related to emotional exhaustion and personal accomplishment, and one-third reported depersonalization and the intent to leave their jobs within a year. A poor nursing practice environment was the leading factor, increasing nurses' burnout levels in all subdimensions. Burnout related to emotional exhaustion, personal accomplishment and poor practice environment increased intention to leave. Permanent positions decreased intention. There was a relationship between poor practice environments and nursing outcomes in Turkey. The use of a survey data collection method is a potential study limitation. Quantitative and qualitative methods could be combined to obtain more detailed objective data about nursing practice environments. Poor practice environments, high-level burnout and intention to leave work are significant problems in Istanbul, Turkey. Favourable practice environments and job security should be provided to improve nursing outcomes. Policymakers and nurse managers should be aware of any negative issues regarding nursing practice environments and job security to improve nursing outcomes. © 2016 International Council of Nurses.

RNs and LPNs: emotional exhaustion and intention to leave.

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.

To identify factors associated with veterinarians leaving a career in rural veterinary practice (RVP). Cross-sectional descriptive study. Veterinarians from the United States who no longer worked in RVP. Veterinarians in any area of practice were solicited to participate in an online survey through invitation letters sent to various veterinary associations. Those who indicated that they had left RVP were asked to rank the importance of various potential factors in their decision to leave RVP. 805 responses were obtained from veterinarians who had worked in RVP, of which 246 (30.6%) had left RVP. Most (231/246 [93.9%]) of those who reported leaving RVP had been in practice > 5 years, and 75.2% (185/246) had been in practice > 12 years. Eighty-three (33.7%) who left RVP pursued careers in urban areas, 72 (29.3%) entered academia, and 7 (2.8%) retired. Reasons for leaving RVP ranked by the highest proportions of respondents as being of high importance were emergency duty, time off, salary, practice atmosphere, and family concerns. Women ranked factors such as time off, mentorship, practice atmosphere, conflict with staff, and gender issues as being of high importance more often than men did. Results suggested that the perceived shortage of veterinarians in RVP may be in part influenced by a lack of retention, particularly among experienced veterinarians. Targeted efforts to tackle issues related to emergency duty, time off, salary, practice atmosphere, and family issues could help alleviate the efflux from RVP.

A population survey of phytoseiid mites and spider mites was conducted on peach leaves and wild plants in Japanese peach orchards having different pesticide practices. The phytoseiid mite species composition on peach leaves and wild plants, as estimated using quantitative sequencing, changed during the survey period. Moreover, it varied among study sites. The phytoseiid mite species compositions were similar between peach leaves and some wild plants, such as Veronica persica, Paederia foetida, Persicaria longiseta, and Oxalis corniculata with larger quantities of phytoseiid mites, especially after mid-summer. A PCR-based method to detect the ribosomal ITS sequences of Tetranychus kanzawai and Panonychus mori from phytoseiid mites was developed. Results showed that Euseius sojaensis (specialized pollen feeder/generalist predator) uses both spider mites as prey in the field.

Relationships between job satisfaction, intentions to leave family practice and actually leaving among family physicians in England.

PubMed

Hann, Mark; Reeves, David; Sibbald, Bonnie

2011-08-01

A national survey of family physicians working in the National Health Service (NHS) of England in 2001 revealed that 1/10 under 50 years of age were intending to leave direct patient care within 5 years, and that the principal predictor of their intention to leave was job satisfaction. Our research addressed two questions. First, does a family physician's stated intention to leave their job predict whether or not they actually do leave? Second, to what extent does job satisfaction predict actually leaving? Secondary data analysis was performed on 1174 family physicians aged 50 years and under, who responded to the aforementioned survey. Using data from the annual census of physicians in the NHS, we determined which physicians actually left family practice during the next 5 years. Of the 1174 family physicians studied, 194 (16.5%) had left direct patient care within 5 years. Multivariate regression showed that job satisfaction predicted a physician's intention to leave direct patient care and that intention to leave predicted actually leaving. Logically, job satisfaction should then have predicted actual leaving. Our findings, however, suggest that this is only partly true. Although higher levels of job 'dissatisfaction' were associated with an increased likelihood of leaving, higher levels of job 'satisfaction' did not prevent leaving.

Attenuated total reflectance spectroscopy of plant leaves: A tool for ecological and botanical studies

USGS Publications Warehouse

Ribeiro da Luz, B.

2006-01-01

??? Attenuated total reflectance (ATR) spectra of plant leaves display complex absorption features related to organic constituents of leaf surfaces. The spectra can be recorded rapidly, both in the field and in the laboratory, without special sample preparation. ??? This paper explores sources of ATR spectral variation in leaves, including compositional, positional and temporal variations. Interspecific variations are also examined, including the use of ATR spectra as a tool for species identification. ??? Positional spectral variations generally reflected the abundance of cutin and the epicuticular wax thickness and composition. For example, leaves exposed to full sunlight commonly showed more prominent cutin- and wax-related absorption features compared with shaded leaves. Adaxial vs. abaxial leaf surfaces displayed spectral variations reflecting differences in trichome abundance and wax composition. Mature vs. young leaves showed changes in absorption band position and intensity related to cutin, polysaccharide, and possibly amorphous silica development on and near the leaf surfaces. ??? Provided that similar samples are compared (e.g. adaxial surfaces of mature, sun-exposed leaves) same-species individuals display practically identical ATR spectra. Using spectral matching procedures to analyze an ATR database containing 117 individuals, including 32 different tree species, 83% of the individuals were correctly identified. ??

2010-01-01

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.

Relationships among factors affecting advanced practice registered nurses' job satisfaction and intent to leave: A systematic review.

Han, Robin M; Carter, Patricia; Champion, Jane Dimmitt

2018-02-01

This systematic review explores relationships between advanced practice registered nurses' (APRN) job satisfaction and intent to leave. There exists a dearth of APRN providers compared with the ever-growing need for their services. Furthermore, the organizational costs associated with the APRN turnover are extremely high. It, therefore, behooves practice administrators to understand what factors most contribute to APRN job satisfaction and retention. A search of research databases CINAHL, PubMed, and PsycINFO, using keywords "Advanced Practice Registered Nurse," "job satisfaction," "intent to leave," "anticipated turnover," and "Nurse Practitioner" to yield articles included in this review. The strength of existing evidence for this topic is weak. Studies have found that extrinsic factors, such as administrative support and salary, significantly contribute to job dissatisfaction, whereas intrinsic factors, such as autonomy and finding work meaningful, most significantly contribute to job satisfaction. Additional research is needed to better understand the factors relating to APRN job satisfaction and dissatisfaction, and how those factors influence practitioners' intent to leave. Efforts to improve APRN job satisfaction will have positive implications for provider retention, practices, and patients. Administrators should consider the job satisfaction factors identified herein when implementing practice improvement and retention efforts.

Western Australia facing critical losses in its midwifery workforce: a survey of midwives' intentions.

2013-05-01

the ongoing attrition of the midwifery workforce frustrates future workforce planning and the provision of maternity services in Western Australia. This project determined factors contributing to the intention of the midwives to move jobs and/or leave the profession. a cross-sectional survey approach was taken for this descriptive research utilising a self-administered questionnaire developed by the Nursing and Midwifery Office, Department of Health, Western Australia. public and private health sectors in Western Australia, April-May 2010. 1,600 midwives employed in the public and private health sectors throughout Western Australia were invited to participate: 712 responded (44.5%), one-fifth of the state's registered midwives. most midwives worked part-time in a clinical role in public hospitals. Almost half intended moving jobs within 5 years and/or leaving midwifery. Excluding midwives of retirement age, the most common reasons for intending to move jobs were family commitments, working conditions and role dissatisfaction. Those intending to leave midwifery cited work-life balance, career change and family commitments. Midwives thought addressing the following issues would improve midwifery retention: flexible work arrangements, remuneration, staffing and caseload, workplace culture, professional development and models of care. retaining the midwifery workforce requires attention to workforce practices particularly flexible work arrangements and workloads; models of care to strengthen midwives' relationships with clients and colleagues; and accessible professional development. a review of workplace practices at unit and institution levels is urgently required in Western Australia so that midwives can achieve work-life balance and practice to the full extent of their professional role. These changes are necessary to forestall premature retirement of skilled and experienced midwives from the profession and workforce churn. Crown Copyright © 2012. Published by Elsevier Ltd.

The postharvest quality and shelf life of spinach are greatly influenced by cultural practices. Reduced spinach shelf life is a common quandary in the Salinas Valley, California, where current agronomic practices depend on high nitrogen (N) rates. This study aimed to describe the postharvest fracture properties of spinach leaves in relation to N fertilization, leaf age and spinach cultivar. Force-displacement curves, generated by a puncture test, showed a negative correlation between N fertilization and the toughness, stiffness and strength of spinach leaves (P > 0.05). Younger leaves (leaves 12 and 16) from all N treatments were tougher than older leaves (leaves 6 and 8) (P > 0.05). Leaves from the 50 and 75 ppm total N treatments irrespective of spinach cultivar had higher fracture properties and nutritional quality than leaves from other N treatments (P > 0.05). Total alcohol-insoluble residues (AIR) and pectins were present at higher concentrations in low-N grown plants. These plants also had smaller cells and intercellular spaces than high-N grown leaves (P > 0.05). Observed changes in physicochemical and mechanical properties of spinach leaves due to excess nitrogen fertilization were significantly associated with greater postharvest leaf fragility and lower nutritional quality.

Detection of plant diseases in a fast and simple way is crucial for timely disease control. Conventionally, plant diseases are accurately identified by DNA, RNA or serology based methods which are time consuming, complex and expensive. Mid-infrared spectroscopy is a promising technique that simplifies the detection procedure for the disease. Mid-infrared spectroscopy was used to identify the spectral differences between healthy and infected oilseed rape leaves. Two different sample sets from two experiments were used to explore and validate the feasibility of using mid-infrared spectroscopy in detecting Sclerotinia stem rot (SSR) on oilseed rape leaves. The average mid-infrared spectra showed differences between healthy and infected leaves, and the differences varied among different sample sets. Optimal wavenumbers for the 2 sample sets selected by the second derivative spectra were similar, indicating the efficacy of selecting optimal wavenumbers. Chemometric methods were further used to quantitatively detect the oilseed rape leaves infected by SSR, including the partial least squares-discriminant analysis, support vector machine and extreme learning machine. The discriminant models using the full spectra and the optimal wavenumbers of the 2 sample sets were effective for classification accuracies over 80%. The discriminant results for the 2 sample sets varied due to variations in the samples. The use of two sample sets proved and validated the feasibility of using mid-infrared spectroscopy and chemometric methods for detecting SSR on oilseed rape leaves. The similarities among the selected optimal wavenumbers in different sample sets made it feasible to simplify the models and build practical models. Mid-infrared spectroscopy is a reliable and promising technique for SSR control. This study helps in developing practical application of using mid-infrared spectroscopy combined with chemometrics to detect plant disease.

Survey of parental-leave policies and experiences in Ontario academic departments of psychiatry.

Stewart, D E; Richardson, B; Lent, B

1998-11-01

To analyze psychiatrists' self-reports on a survey of faculty parental leaves conducted in 5 Ontario faculties of medicine. A self-report questionnaire was mailed to all Ontario academic medical faculty members requesting information on demographics, parenting status, knowledge of parental-leave policies, personal and collegial experience of recent parental leave, and opinions about ideal parental-leave policies. The survey yielded a 48.6% response rate (3104 respondents). Of the respondents, 318 (10.2%) were academic psychiatrists and 113 (35.5%) of them had or adopted children since 1990. Of the 113 recent parents, 59 (53.2%) did not know their official university parental-leave policy. Fifty-one (48.1%) psychiatrists had recently taken parental leave (30 female, 21 male). Of these, females (26, 86.7%) were more likely than males (0%) to take more than 8 weeks' leave (P = 0.001). The income paid during parental leave was highly variable. Although 192 (64.4%) psychiatrists recommended that temporary replacements be hired and 175 (59.1%) recommended that the replacements be paid from a common faculty risk pool, replacements were hired for only 7 (13.7%) recent leaves. This replacement rate for psychiatry parental leaves was the second lowest of 8 medical specialties. Several leave takers felt that the leave negatively affected their research (32, 32.7%), administration (24, 23.3%), overall career course (23, 21.5%), colleagues' workload (27, 26.2), clinical work (19, 18.3%), teaching (18, 17.3%) and colleagues' attitudes toward them (11, 10.4%). Although 220 (71.5%) academic psychiatrists recommended paid leave to the primary caregiver for 16 or more weeks, 88 (28.6%) recommended less than the 17-week national standard. For secondary caregivers, 202 (66.0%) academic psychiatrists recommended a paid leave of 1-8 weeks, but 63 (20.6%) recommended paid leave for less than 1 week. One hundred and fifty-four psychiatrists (53.1%) recommended that parental-leave income be composed of usual income excluding clinical earnings, a less generous recommendation than that suggested by academic physicians in family medicine, pediatrics, internal medicine, and surgery. The lack of knowledge of parental-leave policies and the variability in income and duration of parental leaves among Ontario academic psychiatrists call for the development, transmission, and implementation of equitable policies. Common faculty risk pools should be established to pay temporary replacements for parental leaves to facilitate the hiring of replacements and to avoid overburdening remaining colleagues. Strategies to allow new parents to continue their career development, especially in research, need further attention. There are clear discrepancies between what psychiatrists believe to be the vital role of early parenting in child development and what they recommend and provide with regard to parental leave for their colleagues. These discrepancies become more evident when compared with the more generous policies and practices in several other medical specialties.

2016-06-01

Nursing turnover is a major issue for health care managers, notably during the global nursing workforce shortage. Despite the often hierarchical structure of the data used in nursing studies, few studies have investigated the impact of the work environment on intention to leave using multilevel techniques. Also, differences between intentions to leave the current workplace or to leave the profession entirely have rarely been studied. The aim of the current study was to investigate how aspects of the nurse practice environment and satisfaction with work schedule flexibility measured at different organisational levels influenced the intention to leave the profession or the workplace due to dissatisfaction. Multilevel models were fitted using survey data from the RN4CAST project, which has a multi-country, multilevel, cross-sectional design. The data analysed here are based on a sample of 23,076 registered nurses from 2020 units in 384 hospitals in 10 European countries (overall response rate: 59.4%). Four levels were available for analyses: country, hospital, unit, and individual registered nurse. Practice environment and satisfaction with schedule flexibility were aggregated and studied at the unit level. Gender, experience as registered nurse, full vs. part-time work, as well as individual deviance from unit mean in practice environment and satisfaction with work schedule flexibility, were included at the individual level. Both intention to leave the profession and the hospital due to dissatisfaction were studied. Regarding intention to leave current workplace, there is variability at both country (6.9%) and unit (6.9%) level. However, for intention to leave the profession we found less variability at the country (4.6%) and unit level (3.9%). Intention to leave the workplace was strongly related to unit level variables. Additionally, individual characteristics and deviance from unit mean regarding practice environment and satisfaction with schedule flexibility were related to both outcomes. Major limitations of the study are its cross-sectional design and the fact that only turnover intention due to dissatisfaction was studied. We conclude that measures aiming to improve the practice environment and schedule flexibility would be a promising approach towards increased retention of registered nurses in both their current workplaces and the nursing profession as a whole and thus a way to counteract the nursing shortage across European countries.

The impact on breastfeeding of labour market policy and practice in Ireland, Sweden, and the USA.

PubMed

Galtry, Judith

2003-07-01

In recent decades there has been a marked rise in the labour market participation of women with infants in many countries. Partly in response to this trend, there are calls for greater emphasis on infant and child health in research and policy development on parental leave and other work-family balancing measures. Yet achieving high rates of breastfeeding as a health objective has thus far received relatively little attention in this context. Biomedical literature outlines the important health benefits conferred by breastfeeding, including upon infants and young children among middle class populations in developed countries. International recommendations now advise exclusive breastfeeding for 6 months. However, research indicates that the timing of the mother's resumption of employment is a key factor influencing the duration of exclusive breastfeeding. There would thus appear to be considerable potential for labour policy and practice, particularly maternity/parental leave provisions, to positively influence breastfeeding practice. Taking the case studies of Ireland, Sweden, and the United States, this paper explores the implications of labour market and early childhood policy for breastfeeding practice. The equity tensions posed by the breastfeeding-maternal employment intersection are also examined. The paper concludes that both socio-cultural support and labour market/health/early childhood policy are important if high rates of both breastfeeding and women's employment are to be achieved in industrialised countries.

The objectives of present work are twofold. First, we want to verify that hygrine and cuscohygrine are good markers to distinguish between chewing coca leaves and cocaine abuse. Secondly, we try to develop a quick and easy qualitative method to determine the two mentioned markers. We analyzed two kinds of urine samples: the first group consisted of twenty-four (24) subjects: urine samples were obtained from various types of workers (e.g. doctors, chemists, nurses, technicians, painters, contractors, employees and some retired persons) who admitted chewing coca leaves. Frequency of the habit of chewing coca leaves was variable. They practiced "coqueo" between two (2) and forty-four (44) years. Sixteen (16) of them used alkaline substances to enhance the extraction of cocaine from the leaves The second group of urine samples consisted on thirty-eight (38) cocaine abusers, from forensic cases from Spain and Argentina. A GC/MS qualitative method, performed after liquid-liquid extraction, was developed and validated (the parameters studied were selectivity/specificity, LOD and stability), and then applied to the urine samples. Hygrine and cuscohygrine are good markers to distinguish between chewing coca leaves and cocaine abuse, and the qualitative method presented can be used successfully in workplace drug testing and forensic cases.

Wildlife species associated with non-coniferous vegetation in Pacific Northwest conifer forests: A review

USGS Publications Warehouse

Hagar, J.C.

2007-01-01

Non-coniferous vegetation, including herbs, shrubs, and broad-leaved trees, makes a vital contribution to ecosystem function and diversity in Pacific Northwest conifer forests. However, forest management has largely been indifferent or detrimental to shrubs and trees that have low commercial value, in spite of a paradigm shift towards more holistic management in recent decades. Forest management practices that are detrimental to broad-leaved trees and shrubs are likely to decrease habitat diversity for wildlife, but the number of species that may be affected has not previously been enumerated. I reviewed life history accounts for forest-dwelling vertebrate wildlife species and derived a list of 78 species in Oregon and Washington that are associated with non-coniferous vegetation. The diversity of direct and indirect food resources provided was the primary functional basis for associations of most species with non-coniferous vegetation. Thus, a diversity of herbs and broad-leaved trees and shrubs provides the foundation for food webs that contribute to diversity at multiple trophic levels in Pacific Northwest conifer forests. Given the number of species associated with non-coniferous vegetation in conifer-dominated forests, maintaining habitats that support diverse plant communities, particularly broad-leaved trees and shrubs, will be an important component of management strategies intended to foster biodiversity. Silvicultural practices such as modified planting densities, and pre-commercial and commercial thinning, can be used to control stand density in order to favor the development of understory herbs, shrubs, and a diversity of tree species within managed stands. Allowing shrubs and hardwood trees to develop and persist in early seral stands by curtailing vegetation control also would benefit many species associated with non-coniferous vegetation.

Work-family conflict (WFC) has received much attention in athletic training, yet several factors related to this phenomenon have not been examined, specifically a practitioner's sex, occupational setting, willingness to leave the profession, and willingness to use work-leave benefits. To examine how sex and occupational differences in athletic training affect WFC and to examine willingness to leave the profession and use work-leave benefits. Cross-sectional study. Multiple occupational settings, including clinic/outreach, education, collegiate, industrial, professional sports, secondary school, and sales. A total of 246 athletic trainers (ATs) (men = 110, women = 136) participated. Of these, 61.4% (n = 151) were between 20 and 39 years old. Participants responded to a previously validated and reliable WFC instrument. We created and validated a 3-item instrument that assessed willingness to use work-leave benefits, which demonstrated good internal consistency (Cronbach α = 0.88), as well as a single question about willingness to leave the profession. The mean (± SD) WFC score was 16.88 ± 4.4 (range = 5 [least amount of conflict] to 25 [highest amount of conflict]). Men scored 17.01 ± 4.5, and women scored 16.76 ± 4.36, indicating above-average WFC. We observed no difference between men and women based on conflict scores (t244 = 0.492, P = .95) or their willingness to leave the profession (t244 = -1.27, P = .21). We noted differences among ATs in different practice settings (F8,245 = 5.015, P <.001); those in collegiate and secondary school settings had higher reported WFC scores. A negative relationship existed between WFC score and comfort using work-leave benefits (2-tailed r = -0.533, P < .001). Comfort with using work-leave benefits was different among practice settings (F8,245 = 3.01, P = .003). The ATs employed in traditional practice settings reported higher levels of WFC. Male and female ATs had comparable experiences of WFC and willingness to leave the profession.

Environmental degradation through greenhouse emission have spurred nation’s interest on feedstock-based fuel. Yet, development of this clean biofuel is obstructed by the expensive feedstock which takes up most of the production cost. Therefore, as an alternative, utilization of widely available lignocellulosic residues with relatively no commercial significance has been considered. This present work emphasizes on mango (Mangifera indica) leaves one of the most abundant lignocellulosic waste in Malaysia. Through implementation of this biomass for bioethanol production, continuous allowance of air pollution with a deleterious impact to the country’s environment could be reduced. The high concentration of sugar (16-18%w/v) in the form of cellulose and hemicellulose is ultimately the reason behind the selection of these leaves as a substrate for bioethanol production. Hence, in this study, a comparison of biomass composition in Harum Manis, Sunshine and Chokanan mango leaves were conducted to detect the most suitable substrate source to produce biofuel. At the end of the biomass evaluation, Harum Manis mango leaves turned out to be the most competitive bioethanol crop as these leaves reported to be made up of 34.71% cellulose and 44.02% hemicellulose which summed up to give highest fermentable sugar source with a lignin content of 19.45%.

The purposes of this study were to a) estimate the incidence of intensive care units nurses' intention to leave due to working conditions; and b) identify factors predicting this phenomenon. Cross-sectional design. Hospitals and critical care units. Registered nurses (RNs) employed in adult intensive care units. Organizational climate, nurse demographics, intention to leave, and reason for intending to leave were collected using a self-report survey. Nurses were categorized into two groups: a) those intending to leave due to working conditions; and b) others (e.g., those not leaving or retirees). The measure of organizational climate had seven subscales: professional practice, staffing/resource adequacy, nurse management, nursing process, nurse/physician collaboration, nurse competence, and positive scheduling climate. Setting characteristics came from American Hospital Association data and a survey of chief nursing officers. A total of 2,323 RNs from 66 hospitals and 110 critical care units were surveyed across the nation. On average, the RN was 39.5 yrs old (SD = 9.40), had 15.6 yrs (SD = 9.20) experience in health care, and had worked in his or her current position for 8.0 yrs (SD = 7.50). Seventeen percent (n = 391) of the respondents indicated intending to leave their position in the coming year. Of those, 52% (n = 202) reported that the reason was due to working conditions. Organizational climate factors that had an independent effect on intensive care unit nurse intention to leave due to working conditions were professional practice, nurse competence, and tenure (p < .05). Improving professional practice in the work environment and clinical competence of the nurses as well as supporting new hires may reduce turnover and help ensure a stable and qualified workforce.

2005-01-01

Recently, the abuse of ketum, an indigenous psychoactive plant, has received a lot of attention in Malaysia. To help national law enforcement agencies control its abuse, the laboratory of the Forensic Division has developed a procedure for its positive identification. Botanical identification may not be practical or conclusive, owing to the wide range of ketum materials available on the market, including dry macerated leaves, powdered leaves and drinks. In order to confirm that a substance is, in fact, ketum or that a preparation is derived from ketum, gas chromatography-mass spectrometry is used to definitively identify the presence of the psychoactive principle mnitragynine.

In 2014, the Royal Australasian College of Surgeons identified, through internal analysis, a considerable attrition rate within its Surgical Education and Training programme. Within the attrition cohort, choosing to leave accounted for the majority. Women were significantly over-represented. It was considered important to study these 'leavers' if possible. An external group with medical education expertise were engaged to do this, a report that is now published and titled 'A study exploring the reasons for and experiences of leaving surgical training'. During this time, the Royal Australasian College of Surgeons came under serious external review, leading to the development of the Action Plan on Discrimination, Bullying and Sexual Harassment in the Practice of Surgery, known as the Building Respect, Improving Patient Safety (BRIPS) action plan. The 'Leaving Training Report', which involved nearly one-half of all voluntary 'leavers', identified three major themes that were pertinent to leaving surgical training. Of these, one was about surgery itself: the complexity, the technical, decision-making and lifestyle demands, the emotional aspects of dealing with seriously sick patients and the personal toll of all of this. This narrative literature review investigates these aspects of surgical education from the trainees' perspective. © 2018 Royal Australasian College of Surgeons.

A growing number of residents are having babies during residency training. While many businesses are working to improve maternity conditions and benefits for their employees, residency programs are often not prepared to accommodate pregnant residents. This study was conducted to examine the maternity leave experiences of women who delivered infants during their family practice residency training. Program directors from each of the 394 family practice residency programs listed in the 1993 Directory of Family Practice Residency Programs were asked to distribute surveys to female residents who gave birth during their residency training and had returned to work by the time of the study. Of 199 known eligible residents, 171 (86%) completed surveys; these women represented 127 programs located in 36 states and Puerto Rico. Only 56.8% of women were aware of their program having a written maternity leave policy. The average length of maternity leave was 8 weeks; 76% had leaves of 10 weeks or less. For many, the maternity leave was derived from more than one source, including vacation, sick time, or a mother-child elective. Nearly all (88.3%) the women breast-fed, and the mean duration of breast-feeding was more than 19 weeks. In general, participants believed that having a baby during residency was somewhat difficult. Problems frequently encountered by women after their return to work included sleep deprivation and tiredness, difficulty arranging for child care, guilt about child care, and breast-feeding. Factors that detracted most from the childbirth experience were too little sleep, problems arranging for child care, and lack of support from the partner, residency faculty, and other residents. Having a baby during residency is somewhat difficult for the average female resident. Factors that may ease this difficulty include getting adequate sleep and receiving support from one's partner, faculty, and other residents.

Leaving the classroom: a didactic framework for education in environmental sciences

NASA Astrophysics Data System (ADS)

Dopico, Eduardo; Garcia-Vazquez, Eva

2011-06-01

In Continuous Education curricula in Spain, the programs on sciences of the environment are aimed toward understandings of sustainability. Teaching practice rarely leaves the classroom for outdoor field studies. At the same time, teaching practice is generally focused on examples of how human activities are harmful for ecosystems. From a pedagogic point of view, it is less effective to teach environmental science with negative examples such as catastrophe, tragedy, and crisis. Rather, teaching environmental sciences and sustainable development might be focused on positive human-environment relationships, which is both important for the further development of students and educators. Within rural settings, there are many such examples of positive relationships that can be emphasized and integrated into the curriculum. In this article, we propose teaching environmental sciences through immersion in rural cultural life. We discuss how fieldwork serves as a learning methodology. When students are engaged through research with traditional cultural practices of environmental management, which is a part of the real and traditional culture of a region, they better understand how positive pedagogy instead of pedagogy structured around how not-to-do examples, can be used to stimulate the interactions between humans and the environment with their students. In this way, cultural goods serve as teaching resources in science and environmental education. What we present is authentic cases where adults involved in a course of Continuous Education explore `environmentally-friendly' practices of traditional agriculture in Asturias (north of Spain), employing methodologies of cultural studies.

Career satisfaction of Pennsylvanian dentists and dental hygienists and their plans to leave direct patient care.

PubMed

Vick, Brandon

2016-03-01

The aim of this study is to explore a number of practice-related dynamics between dentists and dental hygienists, including their career dissatisfaction, plans to leave direct patient care, hiring difficulties, and full-time work. Data come from the 2013 Pennsylvania Health Workforce Surveys, a sample of 5,771 dentists and 6,023 dental hygienists, and logistic regression is used to estimate the relationships between outcome areas - dissatisfaction, plans to leave patient care, and hiring/job outcomes - and a number of explanatory variables, including demographic and practice characteristics. Dentists working in practices that employ hygienists have lower odds of reporting overall dissatisfaction and of leaving patient care in the next 6 years than those that do not employ hygienists. Dental hygienists that work full-time hours across two or more jobs have higher odds of dissatisfaction than those who work full-time in one job only. Part-time work in a single hygienist job is associated with higher odds of leaving the career, relative to having a single, full-time job. Results suggest that employment of dental hygienists is associated with lower career dissatisfaction and extended careers for dentists. However, a number of dentist characteristics are associated with difficulty hiring hygienists, including rural practice, nonwhite race, and solo ownership. Only 37.5 percent of hygienists work in a single, full-time job, an outcome related to lower dissatisfaction and extended careers for hygienists. Characteristics associated with this job outcome include having an associate degree, having a local anesthesia permit, and not working for a solo practice. © 2015 American Association of Public Health Dentistry.

the WHO (2011) estimates that 350,000 newly trained midwives are needed internationally to meet Goal 5-- Improve Maternal Health--of the 8 Millennium Development Goals established by the United Nations in 2000. Recognizing the challenges in accomplishing this goal, it is also imperative to retain trained midwives in the profession. Little to date has been investigated regarding the factors that lead to experienced midwives leaving the profession prematurely, particularly in low resource countries. in an effort to initiate identification of barriers that limit midwives' ability to continue in practice, a pilot study was conducted with a convenience sample of 58 midwife attendees, representing 12 countries, at the International Confederation of Midwives - Americas Triennial Regional Meeting in 2010. A survey was distributed to midwife respondents to explore potential influences on work retention, including: encounters of adverse outcomes in practice; empowerment to make change in the work setting; and migration. sixty per cent of respondents reported encountering a maternal or newborn death or injury, and 10% had considered leaving the profession. Over 50% of the midwives listed three potential results that could occur after experiencing an adverse outcome in practice. These included: (a) an investigation by a governmental agency; (b) complaints about the midwife via available media; and (c) involvement in a lawsuit. The consequence most frequently cited for not enacting evidence-based changes in the workplace was resistance from obstetrical colleagues. while there are limitations to gathering data from attendees at a professional meeting, this is the first known international survey of midwives regarding factors that may contribute to their leaving the profession at a time when there is an increasing global awareness of the need for a skilled birth attendant at every birth.

2017-03-30

As a natural and healthy beverage, tea is widely enjoyed; however, the pesticide residues in tea leaves affect the quality and food safety. To develop a highly selective and efficient method for the facile removal of pesticide residues, the subcritical butane extraction (SBE) technique was employed, and three variables involving temperature, time and extraction cycles were studied. The optimum SBE conditions were found to be as follows: extraction temperature 45 °C, extraction time 30 min, number of extraction cycles 1, and in such a condition that the extraction efficiency reached as high as 92%. Further, the catechins, theanine, caffeine and aroma components, which determine the quality of the tea, fluctuated after SBE treatment. Compared with the uncrushed leaves, pesticide residues can more easily be removed from crushed leaves, and the practical extraction efficiency was 97%. These results indicate that SBE is a useful method to efficiently remove the bifenthrin, and as appearance is not relevant in the production process, tea leaves should first be crushed and then extracted in order that residual pesticides are thoroughly removed.

Develop a computer simulation model that uses daily meteorological data and farm management practices to predict populations of Trichostrongylus colubriformis, Haemonchus contortus and Teladorsagia (Ostertagia) circumcincta and the evolution of anthelmintic resistance within a sheep flock. Use the model to explore if increased refugia, provided by leaving some adult sheep untreated, would delay development of anthelmintic resistance without compromising nematode control. Compare model predictions with field observations from a breeding flock in Armidale, NSW. Simulate the impact of leaving 1-10% of adult sheep untreated in diverse sheep-grazing systems. Predicted populations of Tr. colubriformis and T. circumcincta were less than those observed in the field, attributed to nutritional stress experienced by the sheep during drought and not accounted for by the model. Observed variation in faecal egg counts explained by the model (R(2) ) for these species was 40-50%. The H. contortus populations and R(2) were both low. Leaving some sheep untreated worked best in situations where animals were already grazing or were moved onto pastures with low populations of infective larvae. In those cases, anthelmintic resistance was delayed and nematode control was maintained when 1-4% of adult stock remained untreated. In general, the model predicted that leaving more than 4% of adults untreated did not sufficiently delay the development of anthelmintic resistance to justify the increased production risk from such a strategy. The choice of a drug rotation strategy had an equal or larger effect on nematode control, and selection for resistance, than leaving 1-10% of adults untreated. © 2011 The Authors.

To evaluate the relationship between burnout, satisfaction with electronic health records and work-life integration, and the career plans of US physicians. Physicians across all specialties in the United States were surveyed between August 28, 2014, and October 6, 2014. Physicians provided information regarding the likelihood of reducing clinical hours in the next 12 months and the likelihood of leaving current practice within the next 24 months. Of 35,922 physicians contacted, 6880 (19.2%) returned surveys. Of the 6695 physicians in clinical practice at the time of the survey (97.3%), 1275 of the 6452 who responded (19.8%) reported it was likely or definite that they would reduce clinical work hours in the next 12 months, and 1726 of the 6496 who responded (26.6%) indicated it was likely or definite that they would leave their current practice in the next 2 years. Of the latter group, 126 (1.9% of the 6695 physicians in clinical practice at the time of the survey) indicated that they planned to leave practice altogether and pursue a different career. Burnout (odds ratio [OR], 1.81; 95% CI, 1.49-2.19; P<.001), dissatisfaction with work-life integration (OR, 1.65; 95% CI, 1.27-2.14; P<.001), and dissatisfaction with the electronic health record (OR, 1.44; 95% CI, 1.16-1.80; P=.001) were independent predictors of intent to reduce clinical work hours and leave current practice. Nearly 1 in 5 US physicians intend to reduce clinical work hours in the next year, and roughly 1 in 50 intend to leave medicine altogether in the next 2 years to pursue a different career. If physicians follow through on these intentions, it could profoundly worsen the projected shortage of US physicians. Copyright © 2017 Mayo Foundation for Medical Education and Research.

Moso bamboos (Phyllostachys edulis) are important forestry plants in southern China, with substantial roles to play in regional economic and ecological systems. Mixing broad-leaved forests and moso bamboos is a common management practice in China, and it is fundamental to elucidate the interactions between broad-leaved trees and moso bamboos for ensuring the sustainable provision of ecosystem services. We examine how the proportion of broad-leaved forest in a mixed managed zone, topology, and soil profile affects the effective productivity of moso bamboos (i.e., those with significant economic value), using linear regression and generalized additive models. Bamboo's diameter at breast height follows a Weibull distribution. The importance of these variables to bamboo productivity is, respectively, slope (25.9%), the proportion of broad-leaved forest (24.8%), elevation (23.3%), gravel content by volume (16.6%), slope location (8.3%), and soil layer thickness (1.2%). Highest productivity is found on the 25° slope, with a 600-m elevation, and 30% broad-leaved forest. As such, broad-leaved forest in the upper slope can have a strong influence on the effective productivity of moso bamboo, ranking only after slope and before elevation. These factors can be considered in future management practice.

Former foster youth's perspectives on independent living preparation six months after discharge.

Jones, Loring P

2014-01-01

Research findings have developed a troubling narrative of youth leaving foster care. Congress attempted to address the post-discharge difficulties of foster youth by passing the Independent Living Initiative in 1986, which mandated that the states develop services that would prepare youth for life after foster care. However, it is unclear what effect these programs have on post-foster care trajectories. This largely qualitative study examined the perceptions of a sample of discharged foster six months after leaving care. Most youth felt prepared for life and foster care. They were also for the most part were satisfied with their independent living program, but had significant dissatisfactions with elements of the program. These satisfactions and dissatisfactions are reported along with suggestions for improvement. The policy and practice implications of these suggestions are considered.

Environmental philosophy is a hybrid discipline drawing extensively from epistemology, ethics, and philosophy of science and analyzing disciplines such as conservation biology, restoration ecology, sustainability studies, and political ecology. The book being discussed both provides an overview of environmental philosophy and develops an anthropocentric framework for it. That framework treats natural values as deep cultural values. Tradeoffs between natural values are analyzed using decision theory to the extent possible, leaving many interesting question for philosophical deliberation. This framework is supposed to be applicable in practical contexts. Copyright © 2013 Elsevier Ltd. All rights reserved.

A national cross-sectional study on nurses' intent to leave and job satisfaction in Lebanon: implications for policy and practice

PubMed Central

El-Jardali, Fadi; Dimassi, Hani; Dumit, Nuhad; Jamal, Diana; Mouro, Gladys

2009-01-01

Background Lebanon is perceived to be suffering from excessive nurse migration, low job satisfaction, poor retention and high turnover. Little is known about the magnitude of nurse migration and predictors of intent to leave. The objective of this study is to determine the extent of nurses' intent to leave and examine the impact of job satisfaction on intent to leave. Intent to leave was explored to differentiate between nurses who intend to leave their current hospital and those intending to leave the country. Methods A cross-sectional design was used to survey nurses currently practicing in Lebanese hospitals. A total of 1,793 nurses employed in 69 hospitals were surveyed. Questions included those relating to demographic characteristics, intent to leave, and the McCloskey Mueller Satisfaction Scale. Univariate descriptive statistics were conducted on sample's demographic characteristics including gender, age, marital status and educational level. Bivariate associations between intent to leave and demographic characteristics were tested using Pearson Chi-square. Differences in satisfaction scores between nurses with and without intent to leave were tested using t-test and ANOVA f-test. A multinomial logistic regression model was created to predict intent to leave the hospital and intent to leave the country. Results An alarming 67.5% reported intent to leave within the next 1 to 3 years, many of whom disclosed intent to leave the country (36.7%). Within nurses who reported an intent to leave the hospital but stay in Lebanon, 22.1% plan to move to a different health organization in Lebanon, 29.4% plan to leave the profession and 48.5% had other plans. Nurses reported being least satisfied with extrinsic rewards. A common predictor of intent to leave the hospital and the country was dissatisfaction with extrinsic rewards. Other predictors of intent to leave (country or hospital) included age, gender, marital status, degree type, and dissatisfaction with scheduling, interaction opportunities, and control and responsibility. Conclusion Study findings demonstrate linkages between job satisfaction, intent to leave, and migration in a country suffering from a nursing shortage. Findings can be used by health care managers and policy makers in managing job satisfaction, intent to leave and nurse migration. PMID:19284613

Interprofessional Education and Practice Guide No. 6: Developing practice-based interprofessional learning using a short placement model.

Anderson, Elizabeth Susan; Ford, Jenny; Kinnair, Daniel James

2016-07-01

Offering undergraduate and post-qualified learners opportunities to take part in, and reflect on, the nature of interprofessional working when in practice remains an important goal for interprofessional educators. There are a plethora of opportunities within hospital and community care for learners to actively participate in health and social care delivery where collaborative practice prevails. However, it remains challenging to know how to establish and sustain meaningful interprofessional practice-based learning. This is because profession-specific teaching is prioritised and many teams are under-resourced, leaving little time for additional teaching activities. In some instances, practitioners lack the knowledge concerning how to design meaningful interprofessional learning and often feel unprepared for this teaching because of limited interprofessional faculty development. Others are simply unaware of the presence of the different students within their practice area. This guide offers key lessons developed over many years for setting up practice-based interprofessional education. The learning model has been adapted and adopted in different settings and countries and offers a method for engaging clinical front-line practitioners in learning with, and from learners who can help support and in some instances advance care delivery.

The Problems of Parental Leave.

2017-10-01

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.

Analyzing Rural Versus Urban Differences in Career Dissatisfaction and Plans to Leave Among Pennsylvanian Physicians.

PubMed

Vick, Brandon

2016-01-01

This study estimates whether physicians in rural Pennsylvania have higher odds of career dissatisfaction and plans to leave patient care in the next 6 years, compared to their urban counterparts. Rural-urban differences were estimated across specific subgroups of physicians (gender, race, and specialty) and with regard to specific sources of career dissatisfaction. The 2012 Pennsylvania Health Workforce Survey of Physicians allowed for analysis of 17,444 physicians younger than 55 years old actively practicing patient care. Multivariate, logistic regression was performed to estimate the associations with 2 outcome areas: career dissatisfaction and plans to leave patient care in the next 6 years. Controls included rural setting, age, sex, race, work hours, specialty, and practice characteristics. Over 12% of under-55 physicians are dissatisfied with their careers and over 18% report plans to leave patient care in the next 6 years. Rural physicians in Pennsylvania have 18.6% higher odds of reporting career dissatisfaction and 29.5% higher odds of leaving patient care in the next 6 years (P < .01 for each) versus their urban counterparts. Rates of dissatisfaction and potential attrition among younger physicians are not insignificant, with a stronger association with rural practice. Given the large number of rural health shortage areas, better understanding this association is important to health care providers and policy makers. Regression results suggest that higher rural odds are related more to physician work (i.e., stress, practice demands, and lack of autonomy) and family situations and less related to income concerns. © 2015 National Rural Health Association.

Family medical leave as a resilience resource for family caregivers.

Swanke, Jayme; Zeman, Laura Dreuth

2009-01-01

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.

Mayer, K L; Ho, H S; Goodnight, J E

2001-06-01

The responsibility for childbearing and child care has a major effect on general surgical residency and subsequent surgical practice. A survey of all graduates from a university general surgical training program between 1989 and 2000. Twenty-seven women and 44 men completed general surgical training at our university during the period, and 42 (59%) responded to our survey. The age at completion of the residency was 34.0 +/- 2.2 years for men and 33.9 +/- 2.8 years for women. During residency, 64% (14/22) of the men and 15% (3/20) of the women had children. At the time of the survey, 21 (95%) of the men and 8 (40%) of the women had children. Most residents (24 [57%] of 42) relied on their spouse for child care. During surgical practice, 18 (43%) indicated that they rely on their spouse; 19 (45%) use day care, home care, or both; and (8%) of 26 are unsatisfied with their current child care arrangement. During training, 38% (5/13) of men and 67% (2/3) of women took time off for maternity leave, paternity leave, or child care. Two of 3 surgeons would like to have had more time off during residency; most men (70%, or 7 of 10) recommended a leave of 1 to 3 months, and all women preferred a 3-month maternity or child care leave of absence. During surgical practice, only 12% (2/17) of men but 64% (7/11) of women have taken time off for either childbearing or child care. Half of the respondents (21/42) have a formal leave of absence policy at work, 52% (11/21) of which are paid leave programs. Although the workweek of our practicing graduates is 69 +/- 16 hours for men and 64 +/- 12 hours for women, 62% (26/42) spend more than 20 hours per week parenting. More than 80% (27/32) would consider a part-time surgical practice for more parenting involvement; one third of the responders suggested that 30 hours a week constitutes a reasonable part-time practice, one third preferred fewer than 30 hours, and one third favored more than 30 hours per week. Data are presented as mean +/- SD. Childbearing and child care may have an enormous impact on one's decision to pursue a career in surgery. To attract and retain the best candidates for future surgeons, formal policies on the availability of child care services in the residency program and the workplace should be studied and implemented. Furthermore, national studies are needed to define appropriate, acceptable workweeks for part-time or flexible practices and the duration of leaves of absence for childbearing or child care.

Exploring the key predictors of retention in emergency nurses.

2012-07-01

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 < 0.001). Engagement was also associated with job satisfaction, compassion satisfaction, compassion fatigue, and burnout (P < 0.05). In an ordinal least-squares model (R(2) = 0.44), 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.

Nurses' work environment and intent to leave in Lebanese hospitals: implications for policy and practice.

2011-02-01

The dual burden of nursing shortages and poor work environments threatens quality of patient care and places additional pressures on resource-stretched health care systems, particularly in the Eastern Mediterranean Region (EMR). There is a paucity of research in the EMR examining the quality of nurses' work environment and its association to nurses' intent to leave their jobs/countries. Systematically examine the characteristics of nurses' work environment and their relation to nurses' intent to leave their jobs within the context of Lebanon. A secondary objective is to assess the utility and validity of the NWI-R within the context of the EMR. A cross-sectional survey design was utilized to survey a total of 1793 registered nurses in 69 Lebanese hospitals. The survey instrument included questions on nurses' background, hospital characteristics, intent to leave, and the Revised Nurse Working Index (NWI-R). Data analysis included descriptive statistics for demographic characteristics, t-test and ANOVA to assess differences in agreement scores, and a multinomial logistic regression model to predict intent to leave. Thematic analysis of open-ended questions was utilized to extract themes that fit under issues relating to nurses' work environment in Lebanese hospitals. The NWI-R subscale with the lowest mean score related to control. Younger nurses had lower scores on organizational support and career development. Regression analysis revealed that for every 1 point score decrease on career development there was a 93% increase in likelihood of reporting intent to leave country. Likewise, for every 1 point score decrease on participation there was an observed 51% and 53% increase in likelihood of reporting intent to leave country and hospital, respectively. Findings show that hospital characteristics (size, accreditation status and presence of a recruitment and retention strategy) were significantly associated with NWI-R subscales. Participation, control and career development were key work environment challenges contributing to the attrition on nurses from Lebanese hospitals. Although some of the issues identified are country specific, others would certainly be relevant to other countries in the EMR. Addressing these challenges would require a strong and coordinated action from governments, professional bodies, policy makers and health managers. Copyright © 2010 Elsevier Ltd.

Early nurse attrition in New Zealand and associated policy implications.

PubMed

Walker, L; Clendon, J

2018-03-01

To examine the factors contributing to nurses choosing to exit the nursing profession before retirement age. Population growth, ageing and growing demand for health services mean increased demand for nurses. Better retention could help meet this demand, yet little work has been done in New Zealand to understand early attrition. An online survey of registered and enrolled nurses and nurse practitioners who had left nursing was used. This study reports analysis of responses from 285 ex-nurses aged under 55. The primary reasons nurses left the profession were as follows: workplace concerns; personal challenges; career factors; family reasons; lack of confidence; leaving for overseas; unwillingness to complete educational requirements; poor work-life balance; and inability to find suitable nursing work. Most nurses discussed their intentions to leave with a family member or manager and most reported gaining transferrable skills through nursing. Nurses leave for many reasons. Implementing positive practice environments and individualized approaches to retaining staff may help reduce this attrition. Generational changes in the nature of work and careers mean that nurses may continue to leave the profession sooner than anticipated by policymakers. If the nursing workforce is to be able to meet projected need, education, recruitment and retention policies must urgently address issues leading to early attrition. In particular, policies improving the wider environmental context of nursing practice and ensuring that working environments are safe and nurses are well supported must be developed and implemented. Equally, national nursing workforce planning must take into account that nursing is no longer viewed as a career for life. © 2017 International Council of Nurses.

Leaves falling gently or fluttering are common phenomenon in nature scenes. The authenticity of leaves falling plays an important part in the dynamic modeling of natural scenes. 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.

Excluding parental grief: A critical discourse analysis of bereavement accommodation in Canadian labour standards.

2015-01-01

Grief following child loss is profoundly destabilizing with serious long-term repercussions for bereaved parents. Employed parents may need time away from work to deal with this loss. The purpose of this study was to reflect upon the ways labour policies and practices respond to parental bereavement. Critical discourse analysis was used to examine labour policies and practices related to employment leave for bereaved parents in Canada. Results were compared to international labour standards. Universally, employment policies provide only for the practical issues of bereavement. Commonly, leave is three days, unpaid, and meant to enable ceremonial obligations. Policies do not acknowledge the long-term suffering caused by grief or the variable intensity of different kinds of loss. Managerial, moral, normative and neoliberal values embedded in these policies efface the intensely personal experience of grief, thereby leaving employees at risk for serious health and workplace safety issues. Bereavement leave currently understands grief as a generic, time-limited state with instrumental tasks and ceremonial obligations. In contrast, research characterizes responses to child loss as intense, highly personal experiences for which healing and recovery can take years. This disconnect is especially problematic when viewed through the lens of employee wellbeing, reintegration and workplace productivity.

Ethics seminars: a best-practice approach to navigating the against-medical-advice discharge.

Patients who sign out or choose to leave the emergency department (ED) against medical advice (AMA) present important challenges. The current approach to the complex legal, ethical, and medical challenges that arise when adult patients decline medical care in the ED would benefit from a systematic best-practice strategy to maximize patient care outcomes, minimize legal risk, and reach the optimal ethical standard for this at-risk population. Professional responsibilities generated during an AMA encounter include determination of patient decision-making capacity, balancing protection of patient autonomy with prevention of harm, providing the best alternatives for patients who decline some or all of the proposed plan, negotiating to encourage patients to stay, planning for subsequent care, and documenting what transpired. We present two cases that illustrate key insights into a best-practice approach for emergency physicians (EPs) to address problems arising when patients want or need to leave the ED prior to completion of their care. We propose a practical, systematic framework, "AIMED" (assess, investigate, mitigate, explain, and document), that can be consistently applied in situations where patients consider leaving or do leave before their evaluations and urgent treatment are complete. Our goal is to maximize patient outcomes, minimize legal risk, and encourage a consistent and ethical approach to these vulnerable patients. © 2014 by the Society for Academic Emergency Medicine.

The Galaxen model--a concept for rehabilitation and prevention in the construction industry.

PubMed

Stenlund, Berndt

2005-01-01

The Galaxen model was developed during the late 1980s to provide rehabilitation and prevention activities in the construction industry. It handles around 1200 workers with long-term sick leave or partial disabilities annually, some 10% of whom annually leave Galaxen for an ordinary job without a wage subsidy. The model includes a decision by a rehabilitation board of representatives from the employers, the trade union, and the regional employment office, a rehabilitation plan, allotment of a case manager, wage subsidies from the State to the company, a search for a suitable job in relation to the partial disability. It also includes a preventive program with emphasis on practical ergonomics. The Galaxen model has proved to be a suitable means of rehabilitating construction workers and returning them to the workforce. The model was developed within the Swedish social security system but could well be adjusted to other contexts.

Systemic regulation of leaf anatomical structure, photosynthetic performance, and high-light tolerance in sorghum.

PubMed

Jiang, Chuang-Dao; Wang, Xin; Gao, Hui-Yuan; Shi, Lei; Chow, Wah Soon

2011-03-01

Leaf anatomy of C3 plants is mainly regulated by a systemic irradiance signal. Since the anatomical features of C4 plants are different from that of C3 plants, we investigated whether the systemic irradiance signal regulates leaf anatomical structure and photosynthetic performance in sorghum (Sorghum bicolor), a C4 plant. Compared with growth under ambient conditions (A), no significant changes in anatomical structure were observed in newly developed leaves by shading young leaves alone (YS). Shading mature leaves (MS) or whole plants (S), on the other hand, caused shade-leaf anatomy in newly developed leaves. By contrast, chloroplast ultrastructure in developing leaves depended only on their local light conditions. Functionally, shading young leaves alone had little effect on their net photosynthetic capacity and stomatal conductance, but shading mature leaves or whole plants significantly decreased these two parameters in newly developed leaves. Specifically, the net photosynthetic rate in newly developed leaves exhibited a positive linear correlation with that of mature leaves, as did stomatal conductance. In MS and S treatments, newly developed leaves exhibited severe photoinhibition under high light. By contrast, newly developed leaves in A and YS treatments were more resistant to high light relative to those in MS- and S-treated seedlings. We suggest that (1) leaf anatomical structure, photosynthetic capacity, and high-light tolerance in newly developed sorghum leaves were regulated by a systemic irradiance signal from mature leaves; and (2) chloroplast ultrastructure only weakly influenced the development of photosynthetic capacity and high-light tolerance. The potential significance of the regulation by a systemic irradiance signal is discussed.

Turnover intention among hospital-based registered nurses in the Eastern Caribbean.

Lansiquot, Beverley Anne; Tullai-McGuinness, Susan; Madigan, Elizabeth

2012-06-01

Vacancy rates for nurses in the English-speaking Caribbean are estimated at 30% with turnover typically associated with migration. The purpose of this study was to describe the characteristics of hospital-based registered nurses (RNs) in the sub-region, their practice environment and turnover intention in two and five years, respectively, and to determine the relationships among practice environment characteristics and turnover intention. A descriptive correlational design was used with self-reported questionnaires from a convenience sample of 301 RNs working in hospitals in four English speaking Eastern Caribbean countries. Single-item visual analog scales (VAS) were used to measure turnover intention in 2 years and 5 years. The Practice Environment Scale of the Nursing Work Index (PES-NWI) measured the characteristics in the practice environment. The mean age of the nurses was 32.5 (SD = 6.75) years. Most nurses (58.8%) were single and 91.4% had relatives living abroad. Nurses scored three PES-NWI subscales < 2.5, indicating a less positive practice environment: resource adequacy, nurse participation in hospital affairs, and nurse managers' ability, leadership, and support. The subscale for collegial nurse-physician relations received the best rating (mean = 2.61, SD = .62). For 2-year intention to leave, the mean rating on the 100-mm VAS was 63.2, while that for the 5-year intention to leave was 65.6. No significant correlations were found among four of the five PES-NWI subscales and turnover intention in 2 and 5 years. The practice environment, while generally unfavorable, is not associated with the nurses' intention to leave their jobs. These findings support the current policy position that calls for managing turnover among nurses. Nursing and health system administrators should assess, plan, and implement workforce policies to slow the outflow of nurses. Initiatives to improve the work environment and the delivery of high-quality care are important to RNs in the Eastern Caribbean. Managing the negative impact of continuous outflow of nurses through turnover requires long-term coordinated policy and human resource development and management initiatives to sustain the supply of RNs in the subregion. © 2012 Sigma Theta Tau International.

Early career experiences and perceptions - a qualitative exploration of the turnover of young registered nurses and intention to leave the nursing profession in Finland.

To describe why young registered nurses (RNs) had previously left an organisation and why they intend to leave the profession. Currently, many young registered nurses, including those in Finland, are considering leaving their job or have an intention to leave the profession. An in-depth, descriptive approach was adopted. Data were collected in 2012 from interviews with 15 registered nurses (under the age of 30 years). The interviews were semi-structured and analysed using conventional content analysis. The main questions addressed were: 'Why had the young registered nurses left their previous organisation?' and 'Why do young registered nurses have an intention to leave the profession?' The findings centre on three themes: poor nursing practice environments; lack of support, orientation and mentoring, and nursing as a 'second best' or serendipitous career choice. The first years of nursing are particularly stressful for newly-graduated and inexperienced registered nurses. An in-depth, qualitative approach reveals more complex reasons behind the turnover of registered nurses and intention to leave the profession than questionnaire surveys. Young registered nurses need social support from nurse managers and experienced colleagues to successfully transition into nursing practice environments. Adequate orientation and mentoring programmes are needed to facilitate this transition. © 2014 John Wiley & Sons Ltd.

Background: Due to the increase of sick leave, prolonging working life and the prediction of shortage of skilled workers in the future, health management systems are continuously gaining importance. Employees in a University Hospital are exposed to particular stress factors, which are also reflected in a higher than average amount of sick leave. Against this background, the project "Fit for Work and Life" (FWL) was developed and implemented by the Hannover Medical School (MHH). Aims: FWL aims to maintain, improve or recover the work ability of employees by offering both preventive and rehabilitative treatments. A second goal is to significantly reduce the days of sick leave. Methods: The project was jointly developed and implemented by five MHH departments and the DRV Braunschweig-Hannover (DRV BS-H) according to previously defined principles. It was scientifically evaluated by the following outcomes: average days of sick leave, work ability (WAI), quality of life (SF-36, WHOQOL), coping strategies (FERUS) and effort-reward imbalance (ERI). Results and Conclusions: So far, this project is unique in its concept. It has been successfully implemented in the organisational structures of the MHH. 376 employees have registered during the first project year. Up to now, 182 participants have completed their individual programmes. The results show that 60.4% of employees have moderate to poor WAI values. The average of the mental summary scale of the SF-36 was 44.9, indicating a high workload. © Georg Thieme Verlag KG Stuttgart · New York.

Korean older intimate partner violence survivors in North America: cultural considerations and practice recommendations.

PubMed

Shim, Woochan S; Nelson-Becker, Holly

2009-01-01

While literature on elder abuse has expanded, elder abuse by intimate partners has been less investigated. Even less is known about intimate partner violence among older Koreans living in North America. This article identifies important cultural considerations for individuals helping the Korean older adult community, beginning with the definition of intimate partner violence in this community and barriers to leaving that include traditional views of the East Asian self. Current practice interventions are discussed and recommendations for future practice such as healing han, the accumulated suffering from years of abuse, are suggested. The ultimate goal of this paper is to expand awareness in order to develop the best culturally competent prevention and intervention practice for Korean older intimate partner violence survivors in North America.

To obtain a 2005 snapshot of New Zealand (NZ) rural primary health care workforce, specifically GPs, general practice nurses and community pharmacists. Postal questionnaires, November 2005. NZ-wide rural general practices and community pharmacies. Rural general practice managers, GPs, nurses, community pharmacy managers and pharmacists. Self-reported data: demographics, country of training, years in practice, business ownership, hours worked including on-call, intention to leave rural practice. General practices: response rate 95% (206/217); 70% GP-owned, practice size ranged from one GP/one nurse to 12 GPs/nine nurses. PHARMACIES: Response rate 90% (147/163). Majority had one (33%) or two (32%) pharmacists; <10% had more than three pharmacists. GPs: response rate 64% (358/559), 71% male, 73% aged >40, 61% full-time, 79% provide on-call, 57% overseas-trained, 78% male and 57% female GPs aged >40; more full-time male GPs (76%) than female (37%) . Nurses: response rate 65% (445/685), 97% female, 72% aged >40, 31% full-time, 28% provide on-call, 84% NZ-trained, 45% consulted independently in 'nurse-clinics' within practice setting. Pharmacists: response rate 96% (248/258), 52% male, 66% aged >40, 71% full-time, 33% provide on-call, 92% NZ-trained, 55% sole/partner pharmacy owners. Many intend to leave NZ rural practice within 5 years: GPs (34%), nurses (25%) and pharmacists (47%). This is the first NZ-wide rural workforce survey to include a range of rural primary health care providers (GPs, nurses and pharmacists). Ageing rural primary health care workforce and intentions to leave herald worsening workforce shortages.

Mechanical stress caused by wind on leaves of Theobroma cacao: Photosynthetic, molecular, antioxidative and ultrastructural responses.

Theobroma cacao is cultivated in the shade, in a so-called 'Cabruca' system, in intercropped with Erithryna or other tree species of economic value, and in full sun as a monoculture in irrigated or chemically-irrigated systems. Since it is a species quite intolerant to wind, it is practically impossible to implant cacao crops under full exposure to the sun, or in areas of frequent winds, without the protection of windbreaks, using arboreal species around the area of culture in the form of box. Wind can cause mechanical stimuli in plants, affecting their growth and development. The objective of this work was to evaluate the photosynthetic changes in mature leaves and the molecular, biochemical and ultrastructural changes in young and mature leaves of the CCN 51 cloned genotype of T. cacao subjected to intermittent (IW) and constant (CW) wind, with velocities of 2.5, 3.5 and 4.5 m s-1, during 3, 6 and 12 h of exposure. It was verified that CW and IW, considering different exposure times, interfered directly in stomatal conductance (gs), transpiration (E) and water use efficiency (WUE), causing a reduction of the photosynthetic rate (A) in mature leaves. In addition, the pulvinus and blade of young and mature leaves, exposed to IW and CW with different exposure times (3 and 12 h), showed marked macroscopic and microscopic mechanical injuries resulting from the constant leaf movement. At both speeds, there was rupture of the cell nuclear membrane in pulvinus and the mesophyll tissues, mainly in the young leaves. On the other hand, in young and mature leaves exposed to CW and IW at different speeds and exposure times, there was lipid peroxidation, increased activity of guaiacol (GPX) and ascorbate (APX) peroxidases in most treatments; and altered expression of transcripts of psba and psbo genes related to the phothosynthetic apparatus and Cu-Zn-sod and per genes related to antioxidative enzymes at the rate of 4.5 m s-1. Younger leaves were more intolerant to mechanical stress caused by the wind, since presented greater macro and microscopic damages and, consequently, greater molecular, biochemical and ultrastructural changes. High wind speeds can seriously compromise the development of young leaves of T. cacao plants and affect their productivity.

The percentage of females in the physician workforce is increasing in Japan, as in other countries; however, the working status of female physicians has not been sufficiently investigated. Original data were obtained from the National Survey of Physicians (NSP) conducted by the Ministry of Health, Labour and Welfare, Japan, from 1984 to 2004. We examined the trend of female physicians' areas of practice and analyzed their leave, return to work, and change in areas of practice using cohort data. The percentage of female physicians has increased significantly in recent generations, especially in surgery, surgical subareas of practice, and obstetrics and gynecology. A remarkable increase was found in obstetrics and gynecology among women under 29 years old from 15.4 to 66.2%. The total number of female physicians on leave has been higher than the number of female physicians returning since 1998. The average percentage of those who changed their area of practice was high in surgery (20.7%) and low in pediatrics (5.0%) and obstetrics and gynecology (1.7%). A strategic plan is needed for future health policy to plan for the physician workforce, especially for the areas of practice with increasing proportions of young female physicians.

The latest generation of convolutional neural networks (CNNs) has achieved impressive results in the field of image classification. This paper is concerned with a new approach to the development of plant disease recognition model, based on leaf image classification, by the use of deep convolutional networks. Novel way of training and the methodology used facilitate a quick and easy system implementation in practice. The developed model is able to recognize 13 different types of plant diseases out of healthy leaves, with the ability to distinguish plant leaves from their surroundings. According to our knowledge, this method for plant disease recognition has been proposed for the first time. All essential steps required for implementing this disease recognition model are fully described throughout the paper, starting from gathering images in order to create a database, assessed by agricultural experts. Caffe, a deep learning framework developed by Berkley Vision and Learning Centre, was used to perform the deep CNN training. The experimental results on the developed model achieved precision between 91% and 98%, for separate class tests, on average 96.3%.

Betel leaf in stoma care.

PubMed

Banu, Tahmina; Talukder, Rupom; Chowdhury, Tanvir Kabir; Hoque, Mozammel

2007-07-01

Construction of a stoma is a common procedure in pediatric surgical practice. For care of these stomas, commercially available devices such as ostomy bag, either disposable or of longer duration are usually used. These are expensive, particularly in countries like Bangladesh, and proper-sized ones are not always available. We have found an alternative for stoma care, betel leaf, which is suitable for Bangladeshis. We report the outcome of its use. After construction of stoma, at first zinc oxide paste was applied on the peristomal skin. A betel leaf with shiny, smooth surface outwards and rough surface inwards was put over the stoma with a hole made in the center according to the size of stoma. Another intact leaf covers the stomal opening. When bowel movement occurs, the overlying intact leaf was removed and the fecal matter was washed away from both. The leaves were reused after cleaning. Leaves were changed every 2 to 3 days. From June 1998 to December 2005, in the department of pediatric surgery, Chittagong Medical College and Hospital, Chittagong, Bangladesh, a total of 623 patients had exteriorization of bowel. Of this total, 495 stomas were cared for with betel leaves and 128 with ostomy bags. Of 623 children, 287 had sigmoid colostomy, 211 had transverse colostomy, 105 had ileostomy, and 20 had jejunostomy. Of the 495 children under betel leaf stoma care, 13 patients (2.6%) developed skin excoriation. There were no allergic reactions. Of the 128 patients using ostomy bag, 52 (40.65%) had skin excoriation. Twenty-four (18.75%) children developed some allergic reactions to adhesive. Monthly costs for betel leaves were 15 cents (10 BDT), whereas ostomy bags cost about US$24. In the care of stoma, betel leaves are cheap, easy to handle, nonirritant, and nonallergic.

Paternity leave experiences of NHS doctors.

PubMed

Gordon, Hannah; Szram, Joanna

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.

Teaching laser-induced fluorescence of plant leaves

Lenk, Sándor; Gádoros, Patrik; Kocsányi, László; Barócsi, Attila

2016-11-01

Plants convert carbon dioxide into sugars using the energy of sunlight. Absorbed light unused for conversion is dissipated primarily as heat with a small fraction re-emitted as fluorescence at longer wavelengths. One can use the latter to estimate photosynthetic activity. The illumination of intact leaves with strong light after keeping them in dark for tens of minutes results in a rapid increase followed by a slow decay of fluorescence emission from the fluorophore chlorophyll-a, called the Kautsky effect. This paper describes a laboratory practice that introduces students of physics or engineering into this research field. It begins with the spectral measurement of the fluorescence emitted by a plant leaf upon UV excitation. Then it focuses on the red and far-red components of the fluorescence emission spectrum characteristic to the chlorophyll-a molecule and presents an inexpensive demonstration of the Kautsky effect. As researchers use more complex measurement techniques and tools, the practice ends up with the demonstration of an intelligent fluorosensor, a compact tool developed for plant physiological research and horticulture applications together with a brief interpretation of some important fluorescence parameters.

To examine how front-line registered nurses' perception of their work environment associates with and predicts nurse outcomes in terms of job satisfaction and turnover intention. Mounting evidence has pointed to an inseparable link between attributes of the nursing work environment and nurse outcomes. However, there is a paucity of research examining nurses' perception of their work environment beyond the Western context. This cross-sectional survey involved 1271 registered nurses working in 135 inpatient units in 10 public hospitals in Hong Kong. The instrument comprised items developed from in-depth interviews with front-line nurses that explored nurses' perception of their work environment. Factor analysis identified five dimensions (professionalism, co-worker relationship, management, staffing and resources, and ward practice) of the nursing work environment. Logistic regression analysis further identified professionalism, management and ward practice as significant factors in predicting nurses' turnover intention, and staffing and resources as an additional factor in predicting their job satisfaction. Attributes of the nursing work environment have a significant bearing on nurses' job satisfaction and intention to leave. Managerial effort should focus on improving nurses' work conditions through detailed resource planning, effective management and removal of work constraints that affect nursing practice. © 2012 Blackwell Publishing Ltd.

Objective"Return-to-work Guidance in Occupational Health 2017 (RTW Guidance 2017) " is the first occupational health guide in Japan that evaluates the quality of evidence and offers recommendations based on results of the systematic review of randomized controlled trials. Details of the systematic review of each review question (RQs) will be described separately. This article presents an overview of the method and process of developing the "RTW Guidance 2017."Materials and MethodsThe guidance was developed following the previously-published "Method for developing evidence based occupational health guidance," which included the composition of a highly-transparent guidance developing group as well as the recruitment and selection of RQs. Using the Cochrane Library, PubMed, and Ichushi-Web, a literature search for the six RQs was conducted in January 2016 by partly modifying the search terms of the existing systematic review. Articles were selected according to the inclusion criteria, and the quality of evidence was evaluated using the GRADE approach. Meta-analysis was conducted for RQ2 and RQ4, and a qualitative systematic review was conducted for RQ5, RQ6, and cost-effectiveness. Recommendations were subsequently made after a thorough consideration for feasibility in Japan by examining the costs and available resources.ResultsBased on a comprehensive literature search, eleven RQ2, four RQ4, one RQ5, and three RQ6 were selected. Support program for returning to work, such as "Re-work" for those who are temporarily not working due to musculoskeletal disorders or mental health disorder, was recommended based on moderate evidence (RQ2). For RQ4, the collaboration between occupational health practice and clinical practice was weakly recommended based on low evidence. For RQ5 that evaluated the usefulness of social support, intervention by the manager/co-worker was proposed as a "best practice statement" without indicating it as a recommendation. Work accommodation was weakly recommended based on low evidence in RQ6.Discussion and ConclusionFrom the result of systematic reviews, it was recommended for workers on sick leave more than four weeks regardless of sick leave and sickness absence that interventions during leave would improve work-related outcomes, such as earlier reinstatement. Although there is limited evidence regarding occupational health in Japan, it is important for many occupational health professionals to learn the method of developing guidance and to identify issues for future studies with priority in Japan.

I Want to but I Won't: Pluralistic Ignorance Inhibits Intentions to Take Paternity Leave in Japan.

The number of male employees who take paternity leave in Japan has been low in past decades. However, the majority of male employees actually wish to take paternity leave if they were to have a child. Previous studies have demonstrated that the organizational climate in workplaces is the major determinant of male employees' use of family-friendly policies, because males are often stigmatized and fear receiving negative evaluation from others. While such normative pressure might be derived from prevailing social practices relevant to people's expectation of social roles (e.g., "Men make houses, women make homes"), these social practices are often perpetuated even after the majority of group members have ceased to support them. The perpetuation of this unpopular norm could be caused by the social psychological phenomenon of pluralistic ignorance. While researches have explored people's beliefs about gender roles from various perspectives, profound understanding of these beliefs regarding gender role norms, and the accuracy of others' beliefs remains to be attained. The current research examined the association between pluralistic ignorance and the perpetually low rates of taking paternity leave in Japan. Specifically, Study 1 ( n = 299) examined Japanese male employees' (ages ranging from the 20 s to the 40 s) attitudes toward paternity leave and to estimate attitudes of other men of the same age, as well as behavioral intentions (i.e., desire and willingness) to take paternity leave if they had a child in the future. The results demonstrated that male employees overestimated other men's negative attitudes toward paternity leave. Moreover, those who had positive attitudes toward taking leave and attributed negative attitudes to others were less willing to take paternity leave than were those who had positive attitudes and believed others shared those attitudes, although there was no significant difference between their desires to take paternity leave. Study 2 ( n = 425) replicated these results and further indicated that they could not be explained by the participants' needs to be socially desirable. Together, our findings suggest that pluralistic ignorance occurs in the context of taking paternity leave in Japanese men, and this leads to the low use of available paternity leave.

Calcium localization and tipburn development in lettuce leaves during early enlargement

Barta, D. J.; Tibbitts, T. W.

2000-01-01

Tissue concentrations of Ca, Mg, and K were determined across immature leaves of lettuce (Lactuca sativa L. 'Buttercrunch') at different stages of enlargement using electron microprobe x-ray analysis. The analysis was with a wavelength dispersive spectrometer to permit detection of low concentrations of Ca. Patterns of mineral accumulation in immature leaves that were exposed were compared to patterns of accumulation in leaves that were enclosed within a developing head. The leaves developing without enclosure were free to transpire and developed normally whereas leaves developing with enclosure were restricted in transpiration and developed an injury that was characteristic of Ca deficiency. In the exposed leaves, Ca concentrations increased from an average of 1.0 to 2.1 mg g-1 dry weight (DW) as the leaves enlarged from 5 to 30 mm in length. In the enclosed leaves, Ca concentrations decreased from 1.0 to 0.7 mg g-1 DW as the leaves enlarged from 5 to 30 mm in length. At the tips of these enclosed leaves a larger decrease was found, from 0.9 to 0.3 mg g-1 DW during enlargement. Necrotic injury first became apparent in this tip area when the concentration was approximate to 0.4 mg g-1 DW. Magnesium concentrations across the exposed leaves were similar to concentrations across the enclosed leaves, and did not change with enlargement. Magnesium concentrations averaged 3.5. mg g-1 DW in both enclosed and exposed leaves during enlargement from 5 to 30 mm. In both exposed and enclosed leaves, K concentrations increased during enlargement from 40 to approximate to 60 mg g-1 DW. Potassium concentrations were highest toward the leaf apex and upper margin where injury symptoms occurred, and this may have enhanced injury development. This research documents the critical low levels of Ca (0.2 to 0.4 mg g-1 DW) that can occur in enclosed leaves of plants and which apparently leads to the marginal apex necrosis of developing leaves seen frequently on lettuce and other crops.

Inquiry identity and science teacher professional development

NASA Astrophysics Data System (ADS)

Bryce, Nadine; Wilmes, Sara E. D.; Bellino, Marissa

2016-06-01

An effective inquiry-oriented science teacher possesses more than the skills of teaching through investigation. They must address philosophies, and ways of interacting as a member of a group of educators who value and practice science through inquiry. Professional development opportunities can support inquiry identity development, but most often they address teaching practices from limited cognitive perspectives, leaving unexplored the shifts in identity that may accompany teachers along their journey in becoming skilled in inquiry-oriented instruction. In this forum article, we envision Victoria Deneroff's argument that "professional development could be designed to facilitate reflexive transformation of identity within professional learning environments" (2013, p. 33). Instructional coaching, cogenerative dialogues, and online professional communities are discussed as ways to promote inquiry identity formation and collaboration in ways that empower and deepen science teachers' conversations related to personal and professional efficacy in the service of improved science teaching and learning.

Functional–structural plant modeling (FSPM) is a fast and dynamic method to predict plant growth under varying environmental conditions. Temperature is a primary factor affecting the rate of plant development. In the present study, we used three different temperature treatments (10/14°C, 18/22°C, and 26/30°C) to test the effect of temperature on growth and development of rapeseed (Brassica napus L.) seedlings. Plants were sampled at regular intervals (every 3 days) to obtain growth data during the length of the experiment (1 month in total). Total leaf dry mass, leaf area, leaf mass per area (LMA), width-length ratio, and the ratio of petiole length to leaf blade length (PBR), were determined and statistically analyzed, and contributed to a morphometric database. LMA under high temperature was significantly smaller than LMA under medium and low temperature, while leaves at high temperature were significantly broader. An FSPM of rapeseed seedlings featuring a growth function used for leaf extension and biomass accumulation was implemented by combining measurement with literature data. The model delivered new insights into growth and development dynamics of winter oilseed rape seedlings. The present version of the model mainly focuses on the growth of plant leaves. However, future extensions of the model could be used in practice to better predict plant growth in spring and potential cold damage of the crop. PMID:28377775

Moringa oleifera Lam. has been used as a traditional medicine for the treatment of numerous diseases. A simultaneous high-performance liquid chromatography (HPLC) analysis was developed and validated for the determination of the contents of crypto-chlorogenic acid, isoquercetin and astragalin, the primary antioxidative compounds, in M. oleifera leaves. HPLC analysis was successfully conducted by using a Hypersil BDS C18 column, eluted with a gradient of methanol-1% acetic acid with a flow rate of 1 mL/min, and detected at 334 nm. Parameters for the validation included linearity, precision, accuracy and limits of detection and quantitation. The developed HPLC method was precise, with relative standard deviation < 2%. The recovery values of crypto-chlorogenic acid, isoquercetin and astragalin in M. oleifera leaf extracts were 98.50, 98.47 and 98.59%, respectively. The average contents of these compounds in the dried ethanolic extracts of the leaves of M. oleifera collected from different regions of Thailand were 0.081, 0.120 and 0.153% (w/w), respectively. The developed HPLC method was appropriate and practical for the simultaneous analysis of crypto-chlorogenic acid, isoquercetin and astragalin in the leaf extract of M. oleifera. This work is valuable as guidance for the standardization of the leaf extracts and pharmaceutical products of M. oleifera. © The Author [2013]. Published by Oxford University Press.

Leaf anatomy and the stomatal development of developing leaves of plants have been shown to be regulated by the same light environment as that of mature leaves, but no report has yet been written on whether such a long-distance signal from mature leaves regulates the total leaf area of newly emerged leaves. To explore this question, we created an investigation in which we collected data on the leaf area, leaf mass per area (LMA), leaf anatomy, cell size, cell number, gas exchange and soluble sugar content of leaves from three soybean varieties grown under full sunlight (NS), shaded mature leaves (MS) or whole plants grown in shade (WS). Our results show that MS or WS cause a marked decline both in leaf area and LMA in newly developing leaves. Leaf anatomy also showed characteristics of shade leaves with decreased leaf thickness, palisade tissue thickness, sponge tissue thickness, cell size and cell numbers. In addition, in the MS and WS treatments, newly developed leaves exhibited lower net photosynthetic rate (Pn), stomatal conductance (Gs) and transpiration rate (E), but higher carbon dioxide (CO 2 ) concentration in the intercellular space (Ci) than plants grown in full sunlight. Moreover, soluble sugar content was significantly decreased in newly developed leaves in MS and WS treatments. These results clearly indicate that (1) leaf area, leaf anatomical structure, and photosynthetic function of newly developing leaves are regulated by a systemic irradiance signal from mature leaves; (2) decreased cell size and cell number are the major cause of smaller and thinner leaves in shade; and (3) sugars could possibly act as candidate signal substances to regulate leaf area systemically.

A relational approach to health practices: towards transcending the agency-structure divide.

PubMed

Veenstra, Gerry; Burnett, Patrick John

2014-02-01

Many health scholars find that Pierre Bourdieu's theory of practice leaves too little room for individual agency. We contend that, by virtue of its relational, field-theoretic underpinnings, the idea of leaving room for agency in Bourdieu's theory of practice is misguided. With agency manifested in interactions and social structures consisting of relations built upon relations, the stark distinction between agency and structure inherent to substantialist thinking is undermined, even dissolved, in a relational field-theoretic context. We also contend that, when treated as relationally bound phenomena, Bourdieu's notions of habitus, doxa, capital and field illuminate creative, adaptive and future-looking practices.

Scully, Rebecca E; Davids, Jennifer S; Melnitchouk, Nelya

2017-08-01

The aim of this study was to perform a large-scale, national survey of physician mothers to define the personal, professional, and financial impact of maternity leave and its relationship to career satisfaction for female physicians in procedural and nonprocedural fields. Little is known about the impact of maternity leave on early career female physicians or how childbearing affects career satisfaction. A nationwide sample of physician mothers completed a 45-question anonymous, secure, online questionnaire regarding the impact of pregnancy and childbearing. One thousand five hundred forty-one respondents were attending physicians during their most recent pregnancy and 393 (25.5%) practiced in a procedural field. Overall, 609 (52.9%) reported losing over $10,000 in income during leave with no significant difference between procedural and nonprocedural fields. Maternity leave was included in only 28.9% of female physicians' most recent contracts. Proceduralists were more likely to report negative impact on referrals by maternity leave [odds ratio (OR) 1.78, 95% confidence interval (95% CI) 1.28-2.47, P = 0.001], a requirement to complete missed shifts (OR 3.04, 95% CI 2.12-4.36, P < 0.001), and owing money to their practice (OR 2.71, 95% CI 1.34-5.50, P = 0.006). Proceduralists were also significantly more likely to report desire to have chosen a less demanding specialty (OR 2.33, 95% CI 1.80-3.02, P < 0.001). Female physicians lose significant income during maternity leave and report high rates of career dissatisfaction, particularly those in procedural specialties. Given these findings, improved family leave policies may help improve career satisfaction for female physicians.

Measuring and Modeling Solute Transport in the Rootzone: Protecting the Receiving Water Environments of the Coral Atolls of Tonga

Intensification of agriculture on the raised coral atolls of the Tongan archipelago, notably through squash-pumpkin production, has lead to increased use of agrichemicals. Agrichemicals, both fertilisers and pesticides, pose a risk to these fragile environments. Sustainable land-management practices are needed for small-island developing states. On Tongatapu, solutes leaving the rootzone of the squash can rapidly find their way to the underlying freshwater lenses. These lenses are hydraulically linked to the internal lagoon, and the fringing reefs. We have used buried, non-suction fluxmeters to monitor both the quantity and quality of drainage leaving the rootzone of squash. Fertiliser is traditionally applied at planting. During establishment of the squash in 2003, some 350 mm of rain fell, with 70 % of this leaving the rootzone of this permeable soil as drainage. The concentration of nitrate-N in the drainage water was measured at around 50 mg-N/L. All of the initial fertiliser dressing had been lost, along with N mineralised from the plowed-in grass. Pesticides are needed in humid tropical environments to control weeds, pests and diseases. These chemicals can leach though the rootzone to contaminate receiving waters. We modeled the transport and fate of the presticides used in squash production, and we developed a Decision Support Tool (DST). Our DST can be used to select the best pesticides for local conditions, to tailor practices for minimising leaching losses below the rootzone, and to avoid the build-up of residues in the soil. This project, funded by the European Union and NZAID, took a multi-disciplinary approach through measurement and modeling protocols. Our DST enabled us to engage the wider community and stakeholders. There has been increased awareness of the impacts and risks associated with productive land management in the fragile hydrological environments of this small-island developing state.

Nurses who work outside nursing.

Duffield, Christine; Pallas, Linda O'Brien; Aitken, Leanne M

2004-09-01

The desire to care for people, a family history of professional health care work, and security in career choice are documented reasons for entering nursing. Reasons for leaving include workload, unsafe work environments and harassment. The relationship between these factors and the time nurses spend in the profession has not been explored. This paper reports a study with people who have left nursing, to investigate why they became a nurse, how long they stayed in nursing, and their reasons for leaving. A questionnaire was mailed to Registered Nurses currently working outside nursing, seeking respondents' reasons for entering and leaving nursing, and perceptions of the skills gained from nursing and the ease of adjustment to working in a non-nursing environment. Data analysis included descriptive statistics, exploratory and confirmatory factor analysis, correlational analysis and linear and multiple regression analysis. A model incorporating the factors 'altruistic reasons', 'default choice' and 'stepping stone' explained 36.2% of the variance in reasons for becoming a nurse. A model incorporating the factors 'legal and employer', 'external values and beliefs about nursing', 'professional practice', 'work life/home life' and 'contract requirements' explained 55.4% of the variance in reasons for leaving nursing. Forty-eight per cent of the variance in tenure in nursing practice was explained through personal characteristics of nurses (36%), reasons for becoming a nurse (7%) and reasons for leaving (6%). The reasons why nurses entered or left the profession were varied and complex. While personal characteristics accounted for a large component of tenure in nursing, those managing the nursing workforce should consider professional practice issues and the balance between work life and home life.

Employee (Dis)Engagement: Learning from Nurses Who Left Organizational Jobs for Independent Practice.

PubMed

Stahlke Wall, Sarah

2015-09-01

Employee engagement is of growing interest in healthcare organizations. Engaged employees give an extra measure of effort to contribute to organization goals, whereas disengaged employees withdraw, have lower performance and are more likely to leave their jobs. The aim of this ethnographic study was, in part, to explore the reasons why high-calibre nurses became disengaged from their work and opted to leave their hospital-based employment in favour of independent practice, as well as to consider the organizational conditions that influenced their desire to leave. The findings revealed that nurses left their hospital-based jobs because of health system change, job characteristics, working conditions and lack of respect, which relate closely to the antecedents of employee engagement. Employee engagement can be fostered through organizational support, trust-building management behaviour and transformational leadership. Copyright © 2015 Longwoods Publishing.

Considering the potential threat of vegetables growing in antibiotic-polluted soil with high abundance of antibiotic-resistant genes (ARGs) against human health through the food chain, it is thus urgent to develop novel control technology to ensure vegetable safety. In the present work, pot experiments were conducted in lettuce cultivation to assess the impedance effect of biochar amendment on soil sulfonamides (SAs), antibiotic-resistant bacteria (ARB), and ARG enrichment in lettuce tissues. After 100 days of cultivation, lettuce cultivation with biochar amendment exhibited the greatest soil SA dissipation as well as the significant improvement of lettuce growth indices, with residual soil SAs mainly existing as the tightly bound fraction. Moreover, the SA contents in roots and new/old leaves were reduced by one to two orders of magnitude compared to those without biochar amendment. In addition, isolate counts for SA-resistant bacterial endophytes in old leaves and sul gene abundances in roots and old leaves also decreased significantly after biochar application. However, neither SA resistant bacteria nor sul genes were detected in new leaves. It was the first study to demonstrate that biochar amendment can be a practical strategy to protect lettuce safety growing in SA-polluted soil with rich ARB and ARGs. Copyright © 2015 Elsevier B.V.

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

Variation in gymnemic acid content and non-destructive harvesting of Gymnema sylvestre (Gudmar).

PubMed

Pandey, Ashok Kumar; Yadav, Swati

2010-09-01

Madhunashini (Gymnema sylvestre R. Br.) commonly known as 'Gudmar' in Hindi is an important medicinal climber and extensively used in almost all Indian System of Medicine as a remedy for diabetes, rheumatism, cough, ulcer, jaundice, dyspepsia, constipation, eyes pain and also in snakebite. In India, it is found growing in Andhra Pradesh, Bihar, Chhattisgarh, Karnataka, Kerala, Madhya Pradesh, Maharastra, Orissa, Tamil Nadu, Uttar Pradesh and West Bengal. The major phytoconstituents are gymnemic acids, gudmarin and saponins. In the present study, Gymnema germplasm collected from various regions of Madhya Pradesh was evaluated on the basis of their morphological characteristics and gymnemic acid content. Gymnemic acid content in the leaves was estimated by HPLC. We have also standardized the non-destructive harvesting practices of Gudmar. Selective harvesting was done without harming the main plant. Only mature leaves (60%) were hand plucked in the month of October. Second harvest was done in the month of June. Data revealed that gymnemic acid content varied between 0.96% ± 0.03 (Seoni) to 1.58% ±0.03 (Amarkantak). It was also observed that the leaves left at the time of 1(st) harvest during October matured in June at the time of 2(nd) harvest. Non destructive harvesting practice did not have any negative impact on overall development of the plant. It is evident that there is wide variation in the morphological characteristics and gymnemic acid content in G. sylvestre collected from various locations, which can be exploited for further crop improvement programmes.

OBJECTIVE: To compare characteristics of family physicians planning to discontinue or stay in intrapartum care. DESIGN: Self-administered questionnaire. SETTING: Department of Family Practice at Children's and Women's Health Centre of British Columbia. PARTICIPANTS: Ninety-five family physicians who attended at least one birth at the Health Centre between April 1997 and August 1998. MAIN OUTCOME MEASURES: Intention to leave or stay in family practice maternity care, physician characteristics and beliefs. RESULTS: Forty-five percent (43/95) of family physicians planned to leave maternity care within the next 5 years. Physicians planning to leave had more negative attitudes about the alternative birthing centre, doulas, and practising in free-standing settings without on-site obstetricians; were more likely to report missing personal events because they had put their maternity patients first; were less likely to make housecalls during women's labour; and were more likely to be paid through fee-for-service. CONCLUSION: Being paid by fee-for-service, having negative attitudes toward non-traditional maternity care, and conflict between maternity care and personal life were associated with intention to leave intrapartum care.

[New method and instrument to diagnose crop growth status in greenhouse based on spectroscopy].

PubMed

Zhang, Xi-Jie; Li, Min-Zan; Cui, Di; Zhao, Peng; Sun, Jian-Ying; Tang, Ning

2006-05-01

Spectral reflectance of cucumber leaves in greenhouse was measured using an ASD FieldSpec Pro VNIR spectrometer with natural illumination. Two sensitive wavelengths, 527 nm and 762 nm, were selected to evaluate the nitrogen content of the cucumber leaves. A model was established and validated using normal difference color index(NDCI) with the correlation coefficient of 0.881. Based on the above efforts, a handheld spectral instrument was developed to diagnose the growth status of the crop in greenhouse using fiber optics. The instrument was mainly composed of four parts: reflected light acquisition system, light intensity measurement unit, signal conditioning unit, and data acquisition system. The sunlight reflected by the crop was transmitted by the fiber, and passed through the light filter to obtain light at the sensitive wavelengths. Finally it was transformed into electronic signal by the photoelectric transistor, and was used to diagnose the growth status of the crop according to the evaluation model. The result showed that the developed instrument was practical.

Some studies have suggested that young physicians may have different expectations and practice behaviours than their older generational counterparts, including their reasons for wanting to remain or leave a community. This study examined the factors associated with a physician's decision to leave a work location. We compared different generations of physicians to assess whether these factors have changed over generations. We conducted semi-structured, qualitative interviews with 48 physicians who graduated from two Canadian medical schools. We asked each physician about the number and nature of work location changes and the factors related to their decisions to leave each location. Interview transcripts and notes were analysed using a thematic analysis approach. Dissatisfaction with the working environment was the most frequently cited reason for leaving a location for physicians of all generations. Elements which contributed to the quality of the work environment included the collaborative nature of the practice, the relationship with administrators, and access to resources and personnel. For younger physicians, the work environment had to meet their personal expectations for work-life balance. While remuneration level was given by some physicians as the key reason for leaving a location, for others it was the "last straw" if the work environment was poor. A small number of older generation physicians moved in response to political events and/or policies We documented generational differences in physicians' reasons for choosing a work location. We found that a poor work environment was universally the most important reason why a physician chose to leave a location. A few physicians who were unsatisfied with their work location identified level of remuneration as an additional reason for leaving. Some older generation physicians cited political climate as a reason for leaving a work location. While economic factors have largely been the focus of recruitment and retention initiatives, our findings highlight the importance of the work environment and organizational culture on the retention of physicians of all generations.

Metabolic changes of Vitis vinifera berries and leaves exposed to Bordeaux mixture.

2014-09-01

Since the development of Bordeaux mixture in the late 1800's, copper-based fungicides have been widely used against grapevine (Vitis vinifera L.) diseases, mainly in organic but also in conventional viticulture; however their intensive use has raised phytotoxicity concerns. In this study, the composition of grape berries and leaves upon Bordeaux mixture treatment was investigated during the fructification season by a metabolomic approach. Four applications of Bordeaux mixture till 3 weeks before harvest were performed following the regular management practices of organic viticulture. Results showed that the copper-based treatment affected the content in sugars, organic acids, lipids and flavan-3-ols of grapes and leaves at specific developmental stages. Nonetheless, the levels of sucrose, glucose and fructose, and of tartaric and malic acids were not significantly affected in mature grapes. In contrast, a sharp decrease in free natural amino acids was observed, together with a reduction in protein content and in mineral nitrogen forms. The treatment with Bordeaux mixture increased by 7-fold the copper levels in tissue extracts from surface-washed mature berries. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

2015-01-01

The repeated open application test (ROAT) provides useful information regarding allergens in suspected cases of allergic contact dermatitis; however, standardized methodology has not been established. The aim of this study was to assess how ROAT is used in clinical and research settings. We distributed a survey regarding ROAT practice to the American Contact Dermatitis Society and conducted a literature review of ROAT utilization in research. A total of 67 American Contact Dermatitis Society members participated in the survey. Respondents most frequently recommend application of leave-on products twice daily (46.0%) and rinse-off products once daily (43.5%). The most commonly used anatomical sites include the forearm (38.7%) and antecubital fossa (32.3%). Most respondents continue ROAT for 1 (49.2%) or 2 weeks (31.7%). Literature review of 32 studies (26 leave-on, 6 rinse-off) revealed that application frequency is most common at twice daily for both leave-on (96.2%) and rinse-off (50.0%) products. The most common anatomical site is the forearm (62.5%), with an overall study duration of 3 to 4 weeks (65.6%). When comparing ROAT clinical and research practice, the majority trend was consistent for leave-on product application frequency and anatomical site, but not for rinse-off product application frequency, or overall duration. Further research is needed to determine best practice recommendations.

The Prevalence and Distribution of Aging-Friendly Human Resource Practices.

PubMed

Segel-Karpas, Dikla; Bamberger, Peter A; Bacharach, Samuel B

2015-07-01

The aging of the workforce in the developed world has prompted organizations to implement human resource (HR) policies and practices encouraging older workers to defer retirement. However, little is known about the prevalence of such practices, and the organizational factors associated with their adoption. In this study, we used data collected from 2008 to 2009 from a national probability sample of retirement eligible workers in the United States (N = 407) to assess the prevalence of aging-friendly human resource practices (AFHRP), and their organizational predictors. Results indicate that employee wellness programs, unpaid leave, and reassignment based on physical needs are among the most prevalent AFHRP. However, in the vast majority of enterprises, AFHRP are limited. Results also indicate that projected organizational growth and a focus on internal labor market practices are positively associated with the adoption of AFHRP. Organizational size and the degree of unionization, while positively associated with aging-friendly benefits, were inversely associated with flexibility practices. © The Author(s) 2015.

Survey of Usual Practice: Dysphagia Therapy in Head & Neck Cancer Patients

PubMed Central

Krisciunas, Gintas P.; Sokoloff, William; Stepas, Katherine; Langmore, Susan E.

2012-01-01

There is no standardized dysphagia therapy for head and neck cancer patients and scant evidence to support any particular protocol, leaving institutions and individual speech language pathologists (SLPs) to determine their own protocols based on “typical” practices or anecdotal evidence. To gain an understanding of current usual practices, a national internet-based survey was developed and disseminated to SLPs who treat HNC patients. From a random sample of 4,000 ASHA SID 13 members, 1,931 fit the inclusion criteria, and 759 complete responses were recorded for a 39.3% response rate. Results were analyzed by institution type as well as by individual clinical experience. While some interesting trends emerged from the data, a lack of uniformity and consensus regarding best practices was apparent. This is undoubtedly due to a paucity of research adequately addressing the efficacy of any one therapy for dysphagia in the HNC population. PMID:22456699

A triangular approach to integrate research, education and practice in higher engineering education

Heikkinen, Eetu-Pekka; Jaako, Juha; Hiltunen, Jukka

2017-11-01

Separate approaches in engineering education, research and practice are not very useful when preparing students for working life; instead, integration of education, research and industrial practices is needed. A triangular approach (TA) as a method to accomplish this integration and as a method to provide students with integrated expertise is proposed. The results from the application of TA, both at the course and programme level, indicate that the approach is suitable for developing engineering education. The student pass rate for courses where TA has been used has been higher than for previous approaches, and the student feedback has been very positive. Although TA aims to take both theoretical and practical aspects of engineering as well as research and education into account, the approach concentrates mainly on activities and therefore leaves the goals of these activities as well as the values behind these goals uncovered.

Effective strategies for nurse retention in acute hospitals: a mixed method study.

The realization of an organizational context that succeeds to retain nurses within their job is one of the most effective strategies of dealing with nursing shortages. First, to examine the impact of nursing practice environments, nurse staffing and nurse education on nurse reported intention to leave the hospital. Second, to provide understanding of which best practices in the organization of nursing care are being implemented to provide sound practice environments and to retain nurses. 3186 bedside nurses of 272 randomly selected nursing units in 56 Belgian acute hospitals were surveyed. A GEE logistic regression analysis was used to estimate the impact of organization of nursing care on nurse reported intention to leave controlling for differences in region (Walloon, Flanders, and Brussels), hospital characteristics (technology level, teaching status, and size) and nurse characteristics (experience, gender, and age). For the second objective, in-depth semi-structured interviews with the chief nursing officers of the three high and three low performing hospitals on reported intention to leave were held. 29.5% of Belgian nurses have an intention-to-leave the hospital. Patient-to-nurse staffing ratios and nurse work environments are significantly (p<0.05) associated with intention-to-leave. Interviews with Chief Nurse Officers revealed that high performing hospitals showing low nurse retention were--in contrast to the low performing hospitals--characterized by a flat organization structure with a participative management style, structured education programs and career opportunities for nurses. This study, together with the international body of evidence, suggests that investing in improved nursing work environments is a key strategy to retain nurses. Copyright © 2011 Elsevier Ltd.

The literature indicates that physiotherapy triage assessment can be efficient for patients referred for orthopaedic consultation, however long-term follow up of patient reported outcome measures are not available. To report a long-term evaluation of patient-reported health-related quality of life, pain-related disability, and sick leave after a physiotherapy triage assessment of patients referred for orthopaedic consultation compared with standard practice. Patients referred for orthopaedic consultation (n = 208) were randomised to physiotherapy triage assessment or standard practice. The randomised cohort was analysed on an intention-to-treat (ITT) basis. The patient reported outcome measures EuroQol VAS (self-reported health-state), EuroQol 5D-3L (EQ-5D) and Pain Disability Index (PDI) were assessed at baseline and after 3, 6 and 12 months. EQ VAS was analysed using a repeated measure ANOVA. PDI and EQ-5D were analysed using a marginal logistic regression model. Sick leave was analysed for the 12 months following consultation using a Mann-Whitney U-test. The patients rated a significantly better health-state at 3 after physiotherapy triage assessment [mean difference -5.7 (95% CI -11.1; -0.2); p = 0.04]. There were no other statistically significant differences in perceived health-related quality of life or pain related disability between the groups at any of the follow-ups, or sick leave. This study reports that the long-term follow up of the patient related outcome measures health-related quality of life, pain-related disability and sick leave after physiotherapy triage assessment did not differ from standard practice, indicating the possible benefits of implementation of this model of care.

Leaf epidermal micromorphology and mesophyll structure during the development of Populus euphratica heteromorphic leaves, including linear, lanceolate, ovate, dentate ovate, dentate rhombic, dentate broad-ovate and dentate fan-shaped leaves, were studied by using electron and light microscopy. During development of heteromorphic leaves, epidermal appendages (wax crystals and trichomes) and special cells (mucilage cells and crystal idioblasts) increased in all leaf types while chloroplast ultrastructure and stomatal characters show maximum photosynthetic activity in dentate ovate and rhombic leaves. Also, functional analysis by subordinate function values shows that the maximum adaptability to adverse stress was exhibited in the broad type of mature leaves. The 12 heteromorphic leaf types are classified into three major groups by hierarchical cluster analysis: young, developing and mature leaves. Mature leaves can effectively obtain the highest stress resistance by combining the protection of xerophytic anatomy from drought stress, regulation of water uptake in micro-environment by mucilage and crystal idioblasts, and assistant defense of transpiration reduction through leaf epidermal appendages, which improves photosynthetic activity under arid desert conditions. Our data confirms that the main leaf function is differentiated during the developing process of heteromorphic leaves. PMID:26356300

Providing sickness certification is a decision that primary care physicians make on a daily basis. The majority of sickness certification studies in the literature involve a general assessment of physician or patient behaviour without the use of a robust psychological framework to guide research accuracy. To address this deficiency, this study utilized the Theory of Planned Behaviour (TPB) to specifically gauge the intention and other salient predictors related to sickness certification prescribing behaviour amongst primary care physicians. A cross-sectional study was conducted among N = 271 primary care physicians from 86 primary care practices throughout two states in Malaysia. Questionnaires used were specifically developed based on the TPB, consisting of both direct and indirect measures related to the provision of sickness leave. Questionnaire validity was established through factor analysis and the determination of internal consistency between theoretically related constructs. The temporal stability of the indirect measures was determined via the test-retest correlation analysis. Structural equation modelling was conducted to determine the strength of predictors related to intentions. The mean scores for intention to provide patients with sickness was low. The Cronbach α value for the direct measures was good: overall physician intent to provide sick leave (0.77), physician attitude towards prescribing sick leave for patients (0.77) and physician attitude in trusting the intention of patients seeking sick leave (0.83). The temporal stability of the indirect measures of the questionnaire was satisfactory with significant correlation between constructs separated by an interval of two weeks (p < 0.05). Attitudes and subjective norms were identified as important predictors in physician intention to provide sick leave to patients. An integrated behavioural model utilizing the TPB could help fully explain the complex act of providing sickness leave to patients. Findings from this study could assist relevant agencies to facilitate the creation of policies that may help regulate the provision of sickness leave and alleviate the work burden of sickness leave tasks faced by physicians in Malaysia.

We conducted a cross-sectional study of 802 Lebanese mothers to evaluate effect of rapid return to work on their health and that of their child. Breastfeeding practices were also assessed. The duration of maternity leave was insufficient for 72.8% of the women. Rapid return to work could cause physical and psychological problems depending on the type of work. The average length of breastfeeding was 4.7 months and while the average desired length was 10.9 months. Breastfeeding depended on the duration of the maternity leave, the possibility of breaks for breastfeeding and the presence of nurseries at work. Urgent interventions are necessary to prolong maternity leave and promote breastfeeding among working women.

There is an international nursing shortage. Improving the practice environment has been shown to be a successful strategy against this phenomenon, as the practice environment is associated with retention and job satisfaction. The Israeli nurse practice environment has not been measured. The purpose of this study was to measure practice environment characteristics, retention and job satisfaction and to evaluate the association between these variables. A demographic questionnaire, the Practice Environment Scale, and a Job Satisfaction Questionnaire were administered to Israeli acute and intensive care nurses working in 7 hospitals across the country. Retention was measured by intent to leave the organization and work experience. A convenience sample of registered nurses was obtained using a bi-phasic, stratified, cluster design. Data were collected based on the preferences of each unit, either distribution during various shifts or at staff meetings; or via staff mailboxes. Descriptive statistics were used to describe the sample and results of the questionnaires. Pearson Product Moment Correlations were used to determine significant associations among the variables. A multiple regression model was designed where the criterion variable was the practice environment. Analyses of variance determined differences between groups on nurse practice environment characteristics. 610 nurses reported moderate levels of practice environment characteristics, where the lowest scoring characteristic was 'appropriate staffing and resources'. Approximately 9% of the sample reported their intention to leave and the level of job satisfaction was high. A statistically significant, negative, weak correlation was found between intention to leave and practice environment characteristics, with a moderate correlation between job satisfaction and practice environment characteristics. 'Appropriate staffing and resources' was the only characteristic found to be statistically different based on hospital size and geographic region. This study supports the international nature of the vicious cycle that includes a poor quality practice environment, decreased job satisfaction and low nurse retention. Despite the extreme nursing shortage in Israel, perceptions of the practice environment were similar to other countries. Policy makers and hospital managers should address the practice environment, in order to improve job satisfaction and increase retention.

Primary care physicians generally earn less than specialists. Studies of other occupations have identified perception of pay fairness as a predictor of work- and life-related outcomes. We evaluated whether physicians' pay fairness perceptions were associated with their work satisfaction, turnover intention, and personal health. Three thousand five hundred eighty-nine physicians were surveyed. Agreement with "my total compensation is fair" was used to assess pay fairness perceptions. Total compensation was self-reported, and we used validated measures of work satisfaction, likelihood of leaving current practice, and health status. Hierarchical logistic regressions were used to assess the associations between pay fairness perceptions and work/life-related outcomes. A total of 2263 physicians completed surveys. Fifty-seven percent believed their compensation was fair; there was no difference between physicians in internal medicine and non-primary care specialties (P = 0.58). Eighty-three percent were satisfied at work, 70% reported low likelihood of leaving their practice, and 77% rated their health as very good or excellent. Higher compensation levels were associated with greater work satisfaction and lower turnover intention, but most associations became statistically non-significant after adjusting for pay fairness perceptions. Perceived pay fairness was associated with greater work satisfaction (OR, 4.90; 95% CI, 3.94-6.08; P < 0.001), lower turnover intention (OR, 2.46; 95% CI, 2.01-3.01; P < 0.001), and better health (OR, 1.33; 95% CI, 1.08-1.65; P < 0.01). Physicians who thought their pay was fair reported greater work satisfaction, lower likelihood of leaving their practice, and better overall health. Addressing pay fairness perceptions may be important for sustaining a satisfied and healthy physician workforce, which is necessary to deliver high-quality care.

Balance of trade: export-import in family medicine.

PubMed

Pust, Ronald E

2007-01-01

North American family physicians leaving for less-developed countries (LDCs) may not be aware of internationally validated diagnostic and treatment technologies originating in LDCs. Thus they may bring with them inappropriate models and methods of medical care. More useful "exports" are based in sharing our collaborative vocational perspective with dedicated indigenous generalist clinicians who serve their communities. More specifically, Western doctors abroad can promote local reanalyses of international evidence-based medicine (EBM) studies, efficient deployment of scarce clinical resources, and a family medicine/generalist career ladder, ultimately reversing the "brain drain" from LDCs. Balancing these exports, we should import the growing number of EBM best practices originated in World Health Organization and other LDCs research that are applicable in developed nations. Many generalist colleagues, expatriate and indigenous, with long-term LDC experience stand ready to help us import these practices and perspectives.

Reactor monitoring using antineutrino detectors

NASA Astrophysics Data System (ADS)

Bowden, N. S.

2011-08-01

Nuclear reactors have served as the antineutrino source for many fundamental physics experiments. The techniques developed by these experiments make it possible to use these weakly interacting particles for a practical purpose. The large flux of antineutrinos that leaves a reactor carries information about two quantities of interest for safeguards: the reactor power and fissile inventory. Measurements made with antineutrino detectors could therefore offer an alternative means for verifying the power history and fissile inventory of a reactor as part of International Atomic Energy Agency (IAEA) and/or other reactor safeguards regimes. Several efforts to develop this monitoring technique are underway worldwide.

The role of high-involvement work practices and professional self-image in nursing recruits' turnover: A three-year prospective study.

Chênevert, Denis; Jourdain, Geneviève; Vandenberghe, Christian

2016-01-01

The retention of young graduate nurses has become a major management challenge among hospitals in Western countries, which is amplified in a context of aging of populations and an increasing demand for services from patients. Moreover, as it has been reported that 50% of experienced nurses do not recommend a career in nursing, it is likely that retention problems occur not only at the level of the organization, but also at the level of the nursing profession. Although research has identified some predictors of nurse turnover, it is unclear which factors influence nurses' turnover from the organization and from the profession and how these factors interrelate with one another over time. The present study extends previous research on nurse turnover by looking at the combined effects of nurses' pre-entry expectations, perceived high-involvement work practices, and professional self-image, on intended and actual turnover from the organization and the profession. A prospective, longitudinal study of a sample of 160 graduated nurses affiliated with the Quebec Nurses' Association, Canada, was conducted. Participants were surveyed at three points in time, spread over a 3-year period. Graduated nurses' pre-entry expectations and professional self-image were surveyed at graduation (Time 1), while perceived high-involvement work practices, professional self-image, and intention to leave the organization and the profession were captured six months following nurses' entry into the labor market (Time 2). Finally, participants were surveyed with respect to organizational and professional turnover three years after the Time 2 survey (Time 3). Structural equations modeling was used to examine the structure of the measures and the relationships among the constructs. Although pre-entry expectations had no effect, perceived high-involvement work practices were positively related to Time 2, professional self-image (controlling for pre-entry professional self-image). Moreover, high-involvement work practices exerted an indirect, negative effect on organizational and professional turnover through intention to leave the organization, and an indirect negative effect on intention to leave the profession through professional self-image. Nonetheless, professional self-image did not affect turnover. The current study indicates that hospitals and nurse directors can take advantage of developing high-involvement work practices as these practices foster a stronger professional self-image among nurses, thereby contributing to their sense of value as care providers, and indirectly reduce intended and actual turnover from the organization and the profession.

Leaving children at home alone is considered a form of "neglect" in most developed countries. In Japan, this practice is not prohibited, probably because this country is considered to have relatively safe communities for children. The impact of leaving children at home alone on their mental health is a controversial issue, and few studies have examined it to date. The aim of this study was to examine the impact of leaving children aged 6 or 7 years at home alone on their mental health, focusing on both the positive and negative aspects; that is, resilience, difficult behavior, and prosocial behavior. Data from the Adachi Child Health Impact of Living Difficulty (A-CHILD) study were used. The caregivers of all children in the first grade in Adachi City, Tokyo, were targeted, of whom 80% completed the questionnaire ( n = 4,291). Among the analytical sample which comprises those who completed both exposure and outcome variables ( n = 4,195), 2,190 (52.2%) children had never been left at home alone, 1,581 (37.7%) children were left at home alone less than once a week, and 424 (10.1%) children were left at home alone once a week or more. Child resilience was measured using the Children's Resilient Coping Scale, and difficult behavior (emotional symptoms, conduct problems, hyperactivity/inattention, and peer relationship problems) and prosocial behavior using the Strength and Difficulty Questionnaire. Multivariate regression analyses were performed to examine the dose-response association between leaving children at home alone and child mental health, followed by propensity-score matching as a pseudo-randomized controlled trial to reduce potential confounding. The results showed that leaving children at home alone once a week or more, but not less than once a week, was associated with total difficulties scores, especially conduct problems, hyperactivity/inattention, and peer relationship problems. These findings indicate that leaving children at home alone should be avoided in Japan, as is recommended in North America.

McDonald, Penelope W; Dickerson, Suzanne

2013-12-01

The purpose of this study was to determine the common meanings a history of violence has for women out of abusive and violent relationships with an intimate male partner for 5 or more years. To describe the common meanings and shared practices of women who left violent and abusive heterosexual intimate relationships 5 or more years ago, the challenges they face in their current lives, and the resources they use to meet those challenges. An additional aim is to elucidate practical advice they have for others who want to be supportive of the efforts of women recovering from intimate partner violence. An interpretive phenomenological approach using Heideggerian hermeneutics was utilized. Approval of the University Social Sciences Institutional Review Board was obtained. Participants were recruited by means of fliers distributed through a domestic violence listserv and through postings in health clinics in western New York. Interviews were recorded and transcribed. A hermeneutic team approach was used for analysis and interpretation of texts. Twenty-one women of various ages, ethnicities, and backgrounds, who self-identified as being out of abusive relationships for 5 or more years, were interviewed. Six themes were identified: developing and maintaining self reliance; negotiating relationships; creating a safe and supportive environment; challenging societal roles and expectations; nurturing the self; and protecting the children. Engendering independence while living with purpose was the constitutive pattern that unified the themes. Women can successfully establish productive, meaningful lives after violence and will fiercely protect and maintain their independence as they negotiate relationships and developmental challenges throughout their lives. A need for control of their lives and difficulty trusting others remain a lasting legacy of living with a history of violence. This is the first study that examines women's lives 5 or more years after leaving violent and abusive relationships. Findings indicate that women can successfully leave violent and abusive relationships, and challenge the widely accepted notion that women do not leave. © 2013 Sigma Theta Tau International.

To investigate the impact of GDC registration and mandatory CPD on dental nurses' views, job satisfaction and intention to leave. Postal/online survey, conducted in parallel with a survey of dental technicians. UK private and NHS practices, community services, dental hospitals. Representative sample of General Dental Council registrants. Job satisfaction; intention to leave profession (dependent variable in regression analysis). Eleven were ineligible (left profession, moved abroad); 267 (44% of those eligible) responded, all female. Respondents' mean age was 38.2 years (sd 10.74). The general principle of registration was endorsed by 67%, and compulsory registration by 51%, but the fee level by only 6%. Most nurses did not feel that registration had affected their view of dental nursing as a career (56%), their role (74%) or status (86%) within the dental team, or that CPD helped them to do their job better (76%). Fifty-six percent were not satisfied with their job, and 22% intended to leave the profession. Intention to leave was predicted by younger age and greater dissatisfaction with physical working conditions and opportunities to progress. Widely held criticisms regarding the costs and relevance of registration and CPD coupled with a potentially high level of attrition from the profession suggest a review of the fee and salary structure and greater financial support for CPD is warranted.

Variation in gymnemic acid content and non-destructive harvesting of Gymnema sylvestre (Gudmar)

PubMed Central

Pandey, Ashok Kumar; Yadav, Swati

2010-01-01

Background: Madhunashini (Gymnema sylvestre R. Br.) commonly known as ‘Gudmar’ in Hindi is an important medicinal climber and extensively used in almost all Indian System of Medicine as a remedy for diabetes, rheumatism, cough, ulcer, jaundice, dyspepsia, constipation, eyes pain and also in snakebite. In India, it is found growing in Andhra Pradesh, Bihar, Chhattisgarh, Karnataka, Kerala, Madhya Pradesh, Maharastra, Orissa, Tamil Nadu, Uttar Pradesh and West Bengal. The major phytoconstituents are gymnemic acids, gudmarin and saponins. Methods: In the present study, Gymnema germplasm collected from various regions of Madhya Pradesh was evaluated on the basis of their morphological characteristics and gymnemic acid content. Gymnemic acid content in the leaves was estimated by HPLC. We have also standardized the non-destructive harvesting practices of Gudmar. Selective harvesting was done without harming the main plant. Only mature leaves (60%) were hand plucked in the month of October. Second harvest was done in the month of June. Results: Data revealed that gymnemic acid content varied between 0.96% ± 0.03 (Seoni) to 1.58% ±0.03 (Amarkantak). It was also observed that the leaves left at the time of 1st harvest during October matured in June at the time of 2nd harvest. Conclusion: Non destructive harvesting practice did not have any negative impact on overall development of the plant. It is evident that there is wide variation in the morphological characteristics and gymnemic acid content in G. sylvestre collected from various locations, which can be exploited for further crop improvement programmes.

Apker, Julie; Propp, Kathleen M; Ford, Wendy S Zabava

2009-03-01

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.

Some dentists have voluntarily chosen to leave the dental profession despite the considerable time, effort, and financial expenditures involved in their educations. The purpose of this study was to survey the entire population of dentists who had identified themselves as being principally employed in a career outside of clinical practice in the American Dental Association's 1991 Census. A four-page survey was mailed to 654 former dentists, with a total of 237 usable responses (36%). Analysis of major demographic variables showed no significant difference between the survey respondents and the 1992 ADA Survey of Dentists. Major reasons cited by respondents for entering dentistry included professional, financial, and independence factors. Respondents as a group rated their dental school experience as average in degree of difficulty. Clinical dental experience was varied, with a substantially smaller percentage (37%) choosing solo clinical positions than the 1992 ADA Survey of Dentists reported (69%). Reasons for leaving practice included financial, stress, and external regulation concerns. Current careers varied widely, with business, teaching, medicine, and investing being the most common. Respondents ranked their current careers as considerably more favorable on measures of perceived creativity, freedom, belonging, and whether they would choose the same career again. These findings indicate that there was a difference between the perception of a dental career and the reality of clinical practice for the study sample.

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 (/sup 14/C)-sucrose added to the free space of developing leaves, but did not affect import of (/sup 14/C)-sucrose during steady-state /sup 14/CO/sub 2/ labeling of a source leaf. The passively-transported xenobiotic sugar, (/sup 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, (/sup 14/C)-L-glucose translocated through the phloemmore » from a mature leaf, rapidly entered mesophyll cells, and was evenly distributed between mesophyll and veins. Autoradiographs of developing leaves following a pulse of /sup 14/CO/sub 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.« less

In labour market policy and planning, it is important to understand the motivations of people to continue in their current job or to seek other employment. Over the last decade, besides the increasingly medical approach to pregnancy and childbirth and decreasing home births, there were additional dramatic changes and pressures on primary care midwives and midwifery care. Therefore, it is important to re-evaluate the career plans of primary care midwives and their intentions to leave their current job. All 108 primary care midwives of 20 selected midwifery care practices in the Netherlands were invited to fill out a written questionnaire with questions regarding career plans and intentions to leave. Bivariate analyses were carried out to compare career plans and work-related and personal characteristics and attitudes towards work among the group of midwives who indicated that they intended to leave their current job (ITL group) and those who indicated they had no intention to leave (NITL group). Significant predictors of ITL were included in the multiple binary logistic regression with 'intention to leave' as the dependent variable. In 2010, 32.7% of the 98 participating primary care midwives surveyed had considered an intention to leave their current type of job in the past year. Fewer ITL midwives wanted to be a self-employed practitioner with the full range of primary care tasks and work full-time. Significant predictors of the primary care midwives' intention to leave included a lower overall score on the job satisfaction scale (OR = 0.18; 95% CI = 0.06-0.58; p = 0.004) and being between 30 and 45 years old (OR = 2.69; 95% CI = 1.04-7.0; p = 0.041). Our study shows that, despite significant changes in the reproductive, maternal and newborn health service delivery that impact on independent midwifery practice, the majority of primary care midwives intended to stay in primary care. The absence of job satisfaction, and being in the age group between 30 and 45 years old, is associated with primary care midwives' intention to leave their current job. Ongoing monitoring will be important in the future.

To examine changes in the nursing practice environment, retention-related factors, unit stability and patient care tasks delayed or left undone, over two periods between 2004 and 2013. Positive nurse practice environments have been linked to nurse retention and care quality outcomes. The collection of the Practice Environment Scale of the Nursing Work Index, job satisfaction, intent to leave, unit instability and tasks delayed or not done at six acute-care hospitals across three Australian states, in two waves between 2004 and 2013; results from the two waves are compared. On average, practice environment scores declined slightly; nurses reported a greater difficulty in finding another nursing position, lower intent to leave their current job and greater instability in their current position. Rates of delayed tasks increased over the period, whereas rates of tasks left undone have decreased over the period. The decline in nurses' perceptions of the quality of the practice environment is disappointing, particularly given the protracted workforce shortages that have persisted. Significant organisational restructuring and turnover of nurse executives may have contributed to this decline. Managers need to apply existing evidence to improve nurse practice environments and manage instability. © 2016 John Wiley & Sons Ltd.

Association between Sick Leave Prescribing Practices and Physician Burnout and Empathy

PubMed Central

2015-01-01

Objectives To investigate the association between sick leave prescription and physician burnout and empathy in a primary care health district in Lleida, Spain. Methods This descriptive study included 108 primary care doctors from 22 primary care centers in Lleida in 2014 (183,600 patients). Burnout was measured with the Maslach Burnout Inventory and empathy with the Jefferson Scale of Physician Empathy. The reliability of the instruments was measured by calculating Cronbach’s alpha and normal distribution was analyzed using the Kolmogorov-Smirnov-Lilliefors and χ2 tests. Burnout and empathy scores were analyzed by age, sex, and place of work (urban vs rural). Sick leave data were obtained from the Catalan Health Institute. Results High empathy was significantly associated with low burnout. Neither empathy nor burnout were significantly associated with sick leave prescription. Conclusion Sick leave prescription by physicians is not associated with physicians' empathy or burnout and may mostly depend on prescribing guidelines. PMID:26196687

Cocaine abuse is widespread all over the world, and is performed generally by sniffing, injecting or smoking cocaine or crack. The distinction between the recreational use of cocaine from the practice of the so called "coqueo" is still an issue in those countries where this habit is diffused and where it is not considered an addiction, by this reason is necessary to develop a method for to distinguish the coca chewers and cocaine abusers. The use of an unique marker to distinguish between cocaine abuse and chewing of coca leaves is of fundamental importance in those countries where this habit is diffused. Certain alkaloids of the leaves of Erythroxylum coca are lost during the process of extraction/purification of cocaine and it is not possible to find them neither in seizures of chlorhidrate of cocaine nor urine samples of cocaine abusers. These markers are the hygrine and cuscohygrine that are present in the leaves of E. coca. A fast GC/MS method involving a liquid:liquid extraction procedure with tertbutylmethylether (TBME) is proposed for the determination of some alkaloids in cocaine leaves, cocaine seizures and biological samples. All specimens were alkalinized to pH 9 with a carbonate/bicarbonate buffer and then extracted with TBME. The analysis was carry out by GC/MS with electron impact at 70 eV and in full scan mode. The results demonstrate that hygrine and cuscohygrine are not found neither in the urine of cocaine abusers nor in cocaine seizures. For this reason this compounds could be considered as markers of coca chewing. This developed method permits to distinguish coca chewing from cocaine abuse in workplace drug testing through the analysis of urine samples. Copyright © 2012 Elsevier Ireland Ltd.

High vein density, a distinctive trait of C 4 leaves, is central to both C 3 -to-C 4 evolution and conversion of C 3 to C 4 -like crops. We tested the hypothesis that high vein density in C 4 leaves is due to elevated auxin biosynthesis and transport in developing leaves. Up-regulation of genes in auxin biosynthesis pathways and higher auxin content were found in developing C 4 leaves compared with developing C 3 leaves. The same observation held for maize foliar (C 4 ) and husk (C 3 ) leaf primordia. Moreover, auxin content and vein density were increased in loss-of-function mutants of Arabidopsis MYC2 , a suppressor of auxin biosynthesis. Treatment with an auxin biosynthesis inhibitor or an auxin transport inhibitor led to much fewer veins in new leaves. Finally, both Arabidopsis thaliana auxin efflux transporter pin1 and influx transporter lax2 mutants showed reduced vein numbers. Thus, development of high leaf vein density requires elevated auxin biosynthesis and transport.

The dynamics of evaporating sessile droplets on hydrophilic or hydrophobic surfaces is widely studied, and many models for these processes have been developed based on experimental evidence. However, few research has been explored on the evaporation of sessile droplets of surfactant or pesticide solutions on target crop leaves. Thus, in this paper the impact of surfactant concentrations on contact angle, contact diameter, droplet height, and evolution of the droplets’ evaporative volume on rice leaf surfaces have been investigated. The results indicate that the evaporation kinetics of surfactant droplets on rice leaves were influenced by both the surfactant concentrations and the hydrophobicity of rice leaf surfaces. When the surfactant concentration is lower than the surfactant CMC (critical micelle concentration), the droplet evaporation time is much longer than that of the high surfactant concentration. This is due to the longer existence time of a narrow wedge region under the lower surfactant concentration, and such narrow wedge region further restricts the droplet evaporation. Besides, our experimental data are shown to roughly collapse onto theoretical curves based on the model presented by Popov. This study could supply theoretical data on the evaporation of the adjuvant or pesticide droplets for practical applications in agriculture. PMID:28472108

Human resource management practices in a medical complex in the Eastern Cape, South Africa: assessing their impact on the retention of doctors.

2014-03-26

Human resource management (HRM) practices have the potential to influence the retention of doctors in the public health sector. To explore the key human resource (HR) practices affecting doctors in a medical complex in the Eastern Cape, South Africa. We used an open-ended questionnaire to gather data from 75 doctors in this setting. The most important HR practices were paying salaries on time and accurately, the management of documentation, communication, HR staff showing that they respected and valued the doctors, and reimbursement for conferences and special leave requests. All these practices were judged to be poorly administered. Essential HR characteristics were ranked in the following order: task competence of HR staff, accountability, general HR efficiency, occupation-specific dispensation adjustments and performance management and development system efficiency, and availability of HR staff. All these characteristics were judged to be poor. HRM practices in this Eastern Cape medical complex were inadequate and a source of frustration. This lack of efficiency could lead to further problems with regard to retaining doctors in public sector service.

Enriching caregiving practices foster the course and outcome of child development. We studied two developmentally significant domains of positive caregiving -- cognitive and socioemotional -- in more than 127,000 families with under-5 year children from 28 developing countries. Mothers varied widely in cognitive and socioemotional caregiving and engaged in more socioemotional than cognitive activities. More than half of mothers played with their children and took them outside, but only a third or fewer read books and told stories to their children. The GDP of countries related to caregiving after controlling for life expectancy and education. The majority of mothers report that they do not leave their under-5s alone. Policy and intervention recommendations are elaborated. PMID:22277006

The demise of chloroplast DNA in Arabidopsis.

PubMed

Rowan, Beth A; Oldenburg, Delene J; Bendich, Arnold J

2004-09-01

Although it might be expected that chloroplast DNA (cpDNA) would be stably maintained in mature leaves, we report the surprising observation that cpDNA levels decline during plastid development in Arabidopsis thaliana (Col.) until most of the leaves contain little or no DNA long before the onset of senescence. We measured the cpDNA content in developing cotyledons, rosette leaves, and cauline leaves. The amount of cpDNA per chloroplast decreases as the chloroplasts develop, reaching undetectable levels in mature leaves. In young cauline leaves, most individual molecules of cpDNA are found in complex, branched forms. In expanded cauline leaves, cpDNA is present in smaller branched forms only at the base of the leaf and is virtually absent in the distal part of the leaf. We conclude that photosynthetic activity may persist long after the demise of the cpDNA. Copyright 2004 Springer-Verlag

To determine why women choose to enter an academic career in oral and maxillofacial surgery (OMS). An online questionnaire was developed and e-mailed to female OMS surgeons to assess the reasons women choose to pursue an academic career, the perceived positive and negative features of academia for women, and proposed measures to increase the percentage of women choosing to specialize in OMS and pursue an academic career. Thirty-one female OMS surgeons completed the questionnaire; 1 additional participant accessed the survey but did not respond to any of the questions. There were 25 full-time academics and 6 part-time academics (≥50% time commitment). Of the responders, 72% were married, and of these, 72% were married before entering academics. Forty-seven percent of the women had children, all during their academic tenure. Among the full-time academicians with children, only 2 (7.7%) reported moderate difficulty finding the time for childbirth and maternity leave, whereas 3 of the 5 part-time academics with children reported moderate or significant difficulty with childbirth and maternity leave. Factors associated with choosing and enjoying an academic career are involvement in resident-student teaching (78%), followed by colleague camaraderie and collaboration (65.6%), research potential (50%), time flexibility, and not having to deal with excessive "business" practice issues (33%). The main reason for considering leaving an academic OMS career and/or among the least enjoyable aspects of being in academics was the potential for a higher income in private practice (56%). Less significant reasons for considering leaving an academic OMS career were a more flexible work schedule in the private sector and less institutional red tape (37.5%), as well as independence/being in control and more family time (22%). Engaging residents and students by female OMS surgeons, better mentorship from academic OMS surgeons, and increasing the number of women serving in leadership positions in organized OMS were identified as the most important measures to increase female involvement in academic OMS. This study shows that among the major motivating factors for choosing an academic career are involvement in resident-student teaching and colleague camaraderie and collaboration. Additional important factors for making this career choice are the research potential in academia, time flexibility, and not having to deal with excessive business practice issues. The reasons that deter women from entering OMS as a specialty and choosing a full-time academic OMS career are not significantly related to childbirth and family life. The main reason for potentially considering leaving an academic OMS career and/or among the least enjoyable aspects of being in academics is the potential for a higher income in private practice. Other reasons for potentially considering leaving an academic OMS career indicated by this study are independence/being in control and more family time, as well as the lack of institutional red tape. It appears that engaging female residents and students by female OMS surgeons, better mentorship by (both male and female) academic OMS surgeons, and increasing the number of female surgeons who can serve as role models may be beneficial in increasing the number of female OMS surgeons interested in an academic career.

2011-01-01

With the reformed curriculum "4C", the Medical Faculty of the University of Cologne has started to systematically plan practical skills training, for which Clerkship Maturity is the first step. The key guidelines along which the curriculum was development were developed by experts. This approach has now been validated. Both students and teachers were asked to fill in a questionnaire regarding preclinical practical skills training to confirm the concept of Clerkship Maturity. The Cologne training program Clerkship Maturity can be validated empirically overall through the activities of the students awaiting the clerkship framework and through the evaluation by the medical staff providing the training. The subjective ratings of the advantages of the training by the students leave room for improvement. Apart from minor improvements to the program, the most likely solution providing sustainable results will involve an over-regional strategy for establishing skills training planned as part of the curriculum.

Conceptualizing the impacts of dual practice on the retention of public sector specialists - evidence from South Africa.

PubMed

Ashmore, John; Gilson, Lucy

2015-01-19

'Dual practice', or multiple job holding, generally involves public sector-based health workers taking additional work in the private sector. This form of the practice is purported to help retain public health care workers in low and middle-income countries' public sectors through additional wage incentives. There has been little conceptual or empirical development of the relationship between dual practice and retention. This article helps begin to fill this gap, drawing on empirical evidence from a qualitative study focusing on South African specialists. Fifty-one repeat, in-depth interviews were carried out with 28 doctors (predominantly specialists) with more than one job, in one public and one private urban hospital. Findings suggest dual practice can impact both positively and negatively on specialists' intention to stay in the public sector. This is through multiple conceptual channels including those previously identified in the literature such as dual practice acting as a 'stepping stone' to private practice by reducing migration costs. Dual practice can also lead specialists to re-evaluate how they compare public and private jobs, and to overworking which can expedite decisions on whether to stay in the public sector or leave. Numerous respondents undertook dual practice without official permission. The idea that dual practice helps retain public specialists in South Africa may be overstated. Yet banning the practice may be ineffective, given many undertake it without permission in any case. Regulation should be better enforced to ensure dual practice is not abused. The conceptual framework developed in this article could form a basis for further qualitative and quantitative inquiry.

2018-01-01

The first aim of the study was to investigate the effects of flourishing at work (as measured by the Flourishing-at-Work Scale-Short Form) on intention to leave, performance, and organizational citizenship behavior. The second aim was to determine the prevalence of workplace flourishing and to examine differences in the perceived flourishing levels of teachers based on the positive practices they experience in their organization. A sample of 258 secondary school educators in the Gauteng province of South Africa was used in the cross-sectional design. The Flourishing-at-Work Scale-Short Form, Turnover Intention Scale, In-Role Behavior Scale, Organizational Citizenship Behavior Scale, and the Positive Practices Questionnaire were administered. The results showed acceptable psychometric properties for the short scale which measures flourishing. Workplace flourishing negatively predicted intention to leave, while positively predicting in-role performance and organizational citizenship behavior. A total of 44.19% of the population flourished, while 49.22% were moderately mentally healthy and 6.59% languished. Positive organizational practices were associated with flourishing at work.

An electron microprobe was used to determine tissue concentrations of Ca across 20-mm-long leaves of 'Green Lakes' crisphead lettuce (Lactuca sativa L.) with and without tipburn injury. Concentrations within the fifth and 14th leaves, counted from the cotyledons, from plants grown under controlled-environment conditions were compared to concentrations within similar leaves obtained from plants grown under field conditions. Only the 14th leaf from plants grown under controlled-environment conditions developed tipburn. Injured areas on these leaves had Ca concentrations as low as 0.2 to 0.3 mg g-1 dry weight. Uninjured areas of tipburned leaves contained from 0.4 to 0.5 mg g-1 dry weight. Concentrations across the uninjured 14th leaf from field-grown plants averaged 1.0 mg g-1 dry weight. Amounts across the uninjured fifth leaves from both environments averaged 1.6 mg g-1 dry weight. In contrast, Mg concentrations were higher in injured leaves than in uninjured leaves and thus were negatively correlated with Ca concentrations. Magnesium concentrations averaged 4.7 mg g-1 dry weight in injured leaves compared with 3.4 mg g-1 dry weight in uninjured leaves from both environments. Magnesium concentrations were uniform across the leaf. Potassium concentrations were highest at the leaf apex and decreased toward the base and also decreased from the midrib to the margin. Potassium averaged 51 mg g-1 dry weight in injured and uninjured leaves from both environments. No significant differences in K concentration were present between injured and uninjured leaves. This study documented that deficient concentrations of Ca were present in areas of leaf tissue developing tipburn symptoms and that concentrations were significantly higher in similar areas of other leaves that had no symptoms. This study also documented that Ca concentrations were significantly lower in enclosed leaves that exhibited tipburn symptoms than in exposed leaves that did not exhibit tipburn. Also, the amounts of Ca in plants that developed tipburn in controlled environments were lower than in plants of the same cultivar that did not develop tipburn in field plantings. The reduced levels of Ca in plants grown in controlled environments were associated with faster development rates compared with field-grown plants.

A practical Israeli strategy for appealing for organ donation.

PubMed

Ashkenazi, Tamar; Klein, Moti

2013-06-01

CONTEXT-Most reports on organ donation have been related to the importance of support for families, explanations of brain death, and the appeal for organ donation. In contrast, no reports have addressed organ donation from the perspective of intervention in cases of "sudden mourning" and the practical aspects of how to facilitate donation in such cases. OBJECTIVE-To develop a specific strategy for professional intervention in cases of imminent death to bring the family to a state of cognitive and emotional preparedness that will enable them to accept the tragic news, donate organs, and then take leave of the deceased. METHOD-The strategy presented here was developed on the basis of the records of donor coordinators who documented their interaction with families; consultations with professionals in the fields of marketing, persuasion, and negotiating; research conducted on families who did or did not donate organs; and statements made by family members of donors in focus and support groups in more than 10 years. RESULTS-The strategic approach includes early-stage rules such as staff self-awareness, and then later, critical stages of the process that take place before and at the time of determination of brain death: preparation for and the notification of death itself and the request for organ donation, including persuasion skills, coping with resistance and expressions of anger, and physical leave-taking from the deceased. CONCLUSIONS-The flexible, strategic approach set out here is designed to maximize the chances of procuring organ donation while protecting the family's rights and welfare.

Due to the high clinical challenges, differences in coping strategies, and high workload in nurses, there is a need to develop strategies to keep them in the profession. The aim of the present study was to explore the Iranian nurses' coping strategies to deal with intention to leave. A qualitative content analysis was used to obtain rich data. We performed 13 in-depth face-to-face semi-structured interviews with nurses working in hospitals affiliated to Tabriz and Urmia Universities of Medical Sciences in Iran, selected through purposive sampling. Constant comparative method was used for data analysis. Three categories and eleven subcategories emerged during data analysis. The extracted categories and sub-categories consisted of (I) Self-empowerment (practical knowledge increase, responsibility, finding identification of the nurse, balancing work and life, seek support and humanitarian interests), (II) Self-controlling (tolerance, avoidance, the routine-based performance), and (III) Pursuing opportunities for advancement and promotion (community development, planning for higher education). Nurses make attempts to individually manage problems and stressors perceived from bedside that have led them to leave the bedside; these efforts have been effective in some cases but sometimes they are ineffective due to discontinuous training and relative competence in terms of how to manage and deal with problems. It is suggested that nurses should learn strategies scientifically to meet the challenges of bedside. Through enabling and supporting behaviors and creating opportunities for growth and professional development, nursery managers can help nurses to stay and achieve improvement of the quality of cares.

Strawberries are soft fruit that are not recommended to have a post-harvest wash due to quality concerns. Escherichia coli O157:H7 has been linked to outbreaks with strawberries but little is known about the survival of E. coli during the growth cycle of strawberries. The survival of E. coli on strawberry plants during growing under greenhouses conditions was evaluated. Soil, leaves, and strawberries (if present) were artificially contaminated with an E. coli surrogate either at the time of planting, first runner removal (4 wk), second runner removal (8 wk), or one week prior to harvest. At harvest E. coli was recovered from the leaves, soil, and strawberries regardless of the contamination time. Time of contamination influenced (P < 0.05) numbers of viable E. coli on the plant. The highest survival of E. coli (P < 0.0001) was detected in soil that was contaminated at planting (4.27 log10 CFU g soil(-1)), whereas, the survival of E. coli was maximal at later contamination times (8 wk and 1 wk prior to harvest) for the leaves (4.40 and 4.68 log10 CFU g leaves(-1)) and strawberries (3.37 and 3.53 log10 CFU strawberry(-1)). Cross contamination from leaves to fruit was observed during this study, with the presence of E. coli on strawberries which had not been present at the time of contamination. These results indicate that good agricultural best practices to avoid contamination are necessary to minimize the risk of contamination of these popular fruit with enteric pathogens. Practices should include soil testing prior to harvest and avoiding contamination of the leaves. Copyright © 2014 Elsevier Ltd. All rights reserved.

Sickness certification implies that a health problem impairs ability to work. However, its assessment is seldom performed by physicians. Our objective was, therefore, to assess the specific influence of functional and environmental limitations on the length of sick-leave prescriptions. We conducted a cross-sectional study in French general teaching practices and recorded 353 initial sick-leave certifications. For each of them, the functional and environmental limitations were collected using the ATCIF questionnaire, derived from the International Classification of Functioning. Data analysis was based on a linear regression multivariate model. Among the functional limitations, "pain" was the main body function impairment (22% of impairments) and "mobility" the main activity limitation (48%). An environmental barrier was identified in 39% of sick-listed patients, mainly relating to "products and technology" (20%), which refers to workplace factors. The prescription was longer in cases of activity limitations relating to "mobility" and in cases of environmental barriers relating to "products and technology". The multivariate model explained 27% of the variability of sick-leave length through diagnosis elements and only 7% through functional and contextual elements. In sick-leave prescription, a functional and contextual approach, in addition to the traditional diagnosis-based approach, could better support patients' shared understanding and follow-up, and accountability towards health authorities. Implication for Rehabilitation Although sickness certification implies that a health problem impairs ability to work, decision on sick-leave length in general practice is primarily based on diagnosis. A more functional and contextual approach could better support patients' and other health professionals' shared understanding and follow-up, and accountability towards health authorities. Such evolution requires a change of paradigm in medical education, and the way of reasoning of healthcare professionals.

The Berkeley Compass Project is a self-formed group of graduate and undergraduate students in the physical sciences at UC Berkeley. Our goals are to improve undergraduate physics education, provide opportunities for professional development, and increase retention of students from populations typically underrepresented in the physical sciences. Graduate students, together with upper-level undergraduates, design and run all Compass programs. We strive to create a community of educators that incorporates best practices from the science education literature. Along the way, we develop experience in curriculum development, fundraising, grant writing, interfacing with university administration, and other aspects of running an effective organization. Our experience in Compass leaves us better poised to be successful researchers, teachers, and mentors.

Career retention in the dental hygiene workforce in Texas.

Johns, G H; Gutmann, M E; DeWald, J P; Nunn, M E

2001-01-01

The purpose of this study was to determine the factors that influence the retention and attrition of dental hygienists within the workforce in Texas. Respondents' perception of the role of employee benefits and practice of dental hygiene on career retention were explored. Demographic descriptors, including educational level, marital status, age, employment setting, and practice statuses, were also examined. A questionnaire modified from the American Dental Hygienists' Association Extension Study: Retention of Dental Hygienists in the Workforce Final Report, April 1992, was mailed to a systematic sample of licensed Texas dental hygienists in March 1999. Descriptive statistics were computed for dental hygienists currently in practice in Texas and those not in practice at the time of the survey. Differences in demographics, benefits, and attitudes between dental hygienists currently in practice in Texas and dental hygienists not in practice at the time of the survey were tested using independent t-tests for interval data and chi-squared tests for categorical data. All statistical analyses were conducted using the Statistical Package for Social Scientists (SPSS v. 9, Chicago, Illinois). A response rate of 68.1% was obtained. Results revealed the primary reasons for remaining in the practice of dental hygiene were salary, family responsibility, professional collaboration, and variety of work. The primary reasons for leaving dental hygiene practice were family responsibility, boredom, salary, and lack of benefits. Secondary and tertiary reasons stated for staying in clinical practice revealed additional factors including benefits, participation in decision-making, and a safe environment. Dental hygienists in clinical practice were more likely to be employed by a dentist in a single practice and see more patients per day, have a certificate or associate's degree, be unmarried, have fewer children, and be younger than dental hygienists not in practice. The findings suggest that dental hygienists in Texas who remain in the workforce are positively influenced primarily by salary. Dental hygienists in Texas who had left the workforce were primarily influenced to leave practice because of family responsibility. Boredom and lack of benefits were also important factors in deciding to leave clinical practice. Employers of dental hygienists need to be aware of these factors in the hiring process. In addition, dental hygiene educators should prepare students in interviewing techniques for better communication regarding retention factors.

This Consenso Nacional de Hipertensión Arterial Sistémica (National Consensus on Systemic Arterial Hypertension) brings together experiences and joint work of 79 specialists who have been in contact with the patient affected by systemic arterial hypertension. All concepts here presented were outlined on the basis of the real world practice of Mexican hypertensive population. The consensus was developed under strict methodological guidelines. The Delphi technique was applied in two rounds for the development of an appropriate statistical analysis of the concepts exposed by all the specialists, who posed key questions, later developed by the panel of experts of the Hospital de Cardiología, and specialists from the Centro Médico Nacional. Several angles of this illness are shown: detection, diagnosis, pathophysiology, classification, treatment and prevention. The evidence analysis was carried out using PRISMA method. More than 600 articles were reviewed, leaving only the most representative in the references. This document concludes with practical and useful recommendations for the three levels of health care of our country.

Objective To identify factors influencing general practitioners’ (GPs’) decisions about whether or not to remain in direct patient care in general practice and what might help to retain them in that role. Design Qualitative, in-depth, individual interviews exploring factors related to GPs leaving, remaining in and returning to direct patient care. Setting South West England, UK. Participants 41 GPs: 7 retired; 8 intending to take early retirement; 11 who were on or intending to take a career break; 9 aged under 50 years who had left or were intending to leave direct patient care and 6 who were not intending to leave or to take a career break. Plus 19 stakeholders from a range of primary care-related professional organisations and roles. Results Reasons for leaving direct patient care were complex and based on a range of job-related and individual factors. Three key themes underpinned the interviewed GPs’ thinking and rationale: issues relating to their personal and professional identity and the perceived value of general practice-based care within the healthcare system; concerns regarding fear and risk, for example, in respect of medical litigation and managing administrative challenges within the context of increasingly complex care pathways and environments; and issues around choice and volition in respect of personal social, financial, domestic and professional considerations. These themes provide increased understanding of the lived experiences of working in today’s National Health Service for this group of GPs. Conclusion Future policies and strategies aimed at retaining GPs in direct patient care should clarify the role and expectations of general practice and align with GPs’ perception of their own roles and identity; demonstrate to GPs that they are valued and listened to in planning delivery of the UK healthcare; target GPs’ concerns regarding fear and risk, seeking to reduce these to manageable levels and give GPs viable options to support them to remain in direct patient care.

2018-04-01

The pedagogical modelling of everyday classroom practice is an interesting kind of evidence, both for educational research and teachers' own professional development. This paper explores the usage of wearable sensors and machine learning techniques to automatically extract orchestration graphs (teaching activities and their social plane over time), on a dataset of 12 classroom sessions enacted by two different teachers in different classroom settings. The dataset included mobile eye-tracking as well as audiovisual and accelerometry data from sensors worn by the teacher. We evaluated both time-independent and time-aware models, achieving median F1 scores of about 0.7-0.8 on leave-one-session-out k-fold cross-validation. Although these results show the feasibility of this approach, they also highlight the need for larger datasets, recorded in a wider variety of classroom settings, to provide automated tagging of classroom practice that can be used in everyday practice across multiple teachers.

Technology as friend or foe? Do electronic health records increase burnout?

PubMed

Ehrenfeld, Jesse M; Wanderer, Jonathan P

2018-06-01

To summarize recent relevant studies regarding the use of electronic health records and physician burnout. Recently acquired knowledge regarding the relationship between electronic health record use, professional satisfaction, burnout, and desire to leave clinical practice are discussed. Adoption of electronic health records has increased across the United States and worldwide. Although electronic health records have many benefits, there is growing concern about the adverse consequences of their use on physician satisfaction and burnout. Poor usability, incongruent workflows, and the addition of clerical tasks to physician documentation requirements have been previously highlighted as ongoing concerns with electronic health record adoption. In multiple recent studies, electronic health records have been shown to decrease professional satisfaction, increase burnout, and the likelihood that a physician will reduce or leave clinical practice. One interventional study demonstrated a positive effect of a dedicated electronic health record entry clerk on physicians working in an outpatient practice.

Purpose: To develop a practical method for routine QA of the MLC of a Tomotherapy unit using ArcCheck. Methods: Two standard test plans were used in this study. One was a helical test, in which the central leaves No. 32 and 33 opened simultaneously for 277.8ms at projections centered at 0°, 120° and 240° gantry angles. The other test plan was a static test with the gantry angle set at 0°, 45°, 90° and 135° respectively and leaves No. 32 and 33 opened sequentially for total 20s which was further divided into eleven or ten segments at each beam angle.more » The ArcCheck was isocentrically set up and adjusted for couch sag. Movie files which took a snapshot exposure every 50ms were recorded. The start/stop time of leaf open was decided by the ramp-up/ramp-down of the detectors. Results: The percentage differences between measured and planned leaf open time were calculated to be within 0.5% in all the tests. In static test, if leaves are synchronized perfectly, the sum of the two detectors’ signals after normalization should equal one when the leaves are in transition. Our results showed mean values of 0.982, 0.983, 0.978 and 0.995 at static gantry angle 0°, 45°, 90° and 135° respectively. Conclusion: A method for estimating the Tomotherapy binary MLC leaf open time using ArcCheck is proposed and proved to be precise enough to verify the planned leaf open time as small as 277.8ms. This method also makes the observation and quantification of the synchronization of leaves possible.« less

To assess the effects of student debt on the intentions of first-year house officers in relation to location of practice and vocation, and to evaluate the relative importance of incentives to remain practising in New Zealand (NZ). A questionnaire sent to all 296 New Zealand-graduate first-year house officers practicing in New Zealand. The response rate was 53%. Eighty percent of respondents intended to practice in New Zealand for the bulk of their careers; however, 65% of respondents intended to leave New Zealand within 3 years of graduating. The most important factors influencing the decision to leave NZ were overseas travel, financial opportunities, and job/training opportunities. Fifty-five percent of respondents had considered leaving the country, specifically because of the student loan debt. The most important factors influencing vocational intentions were interest, lifestyle, and intellectual challenge. Forty-three percent of respondents stated that their student debt had influenced their intended specialty, and only 9% of respondents indicated their intention to pursue a career in general practice. The highest rated incentives for staying in New Zealand were increased salaries, employer contributions towards student loans, and training opportunities within New Zealand. Student debt influences both emigration and specialty choice intentions of junior doctors in New Zealand. This effect is an unintended but important consequence of our current tertiary education system in New Zealand. These results paint a worrying picture for the junior doctor and general practitioner workforce in New Zealand's future.

To identify the best evidence on the impact of healthcare organizations' supply of nurses and nursing workload on the continuing professional development opportunities of Registered Nurses in the acute care hospital. To maintain registration and professional competence nurses are expected to participate in continuing professional development. One challenge of recruitment and retention is the Registered Nurse's ability to participate in continuing professional development opportunities. The integrative review method was used to present Registered Nurses perspectives on this area of professional concern. The review was conducted for the period of 2001-February 2015. Keywords were: nurs*, continuing professional development, continuing education, professional development, supply, shortage, staffing, workload, nurse: patient ratio, barrier and deterrent. The integrative review used a structured approach for literature search and data evaluation, analysis and presentation. Eleven international studies met the inclusion criteria. Nurses are reluctant or prevented from leaving clinical settings to attend continuing professional development due to lack of relief cover, obtaining paid or unpaid study leave, use of personal time to undertake mandatory training and organizational culture and leadership issues constraining the implementation of learning to benefit patients. Culture, leadership and workload issues impact nurses' ability to attend continuing professional development. The consequences affect competence to practice, the provision of safe, quality patient care, maintenance of professional registration, job satisfaction, recruitment and retention. Organizational leadership plays an important role in supporting attendance at continuing professional development as an investment for the future. © 2015 John Wiley & Sons Ltd.

Buried Versus Exposed Kirschner Wires Following Fixation of Hand Fractures: l Clinician and Patient Surveys.

PubMed

2018-04-01

Fractures of the metacarpals and phalanges are common. Placement of Kirschner wires (K-wires) is the most common form of surgical fixation. After placement, a key decision is whether to bury the end of a K-wire or leave it protruding from the skin (exposed). A recent systematic review found no evidence to support either approach. The aim of study was to investigate current clinical practice, understand the key factors influencing clinician decision-making, and explore patient preferences to inform the design of a randomized clinical trial. The steering group developed surveys for hand surgeons, hand therapists, and patients. Following piloting, they were distributed across the United Kingdom hand surgery units using the Reconstructive Surgery Trials Network. A total of 423 hand surgeons, 187 hand therapists, and 187 patients completed the surveys. Plastic surgeons and junior surgical trainees preferred to leave K-wires not buried. Ease of removal correlated with a decision to leave wires exposed, whereas perceived risk of infection correlated with burying wires. Cost did not affect the decision. Hand therapists were primarily concerned about infection and patient-related outcomes. Patients were most concerned about wire-related problems and pain. This national survey provides a new understanding of the use of K-wires to manage hand fractures in the United Kingdom. A number of nonevidence-based factors seem to influence the decision to bury or leave K-wires exposed. The choice has important clinical and health economic implications that justify a randomized controlled trial.

The aim of the study was to estimate the efficiency of copper (Cu), lead (Pb) and zinc (Zn) phytoextraction by 145 Salix taxa cultivated in an area affected by industrial activity. Survivability and biomass of plants were also analyzed. The highest Cu, Pb and Zn content in shoots was 33.38 ± 2.91 (S. purpurea × viminalis 8), 24.64 ± 1.97 (S. fragilis 1) and 58.99 ± 4.30 (S. eriocephala 7) mg kg -1 dry weight, respectively. In the case of unwashed leaves, the highest content of these metals was 135.06 ± 8.14 (S. purpurea 26), 67.98 ± 5.27 (S. purpurea 45) and 142.56 ± 12.69 (S. alba × triandra 2) mg kg -1 dw, while in washed leaves it was 106.02 ± 11.12 (S. purpurea 45), 55.06 ± 5.75 (S. purpurea 45) and 122.87 ± 12.33 (S. alba × triandra 2) mg kg -1 dw, respectively. The differences between the highest and lowest values for Cu, Pb and Zn were 545%, 20500% and 535% in shoots; 2692%, 2560% and 7500% in unwashed leaves; and 3286%, 2221% and 6950% in washed leaves, respectively. S. acutifolia was able to effectively accumulate all three metals jointly, producing shoots that were well developed in both length and diameter when compared with the other tested willows-an ability that would suggest its high suitability for practical application.

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

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).

The water status in plant leaves is a good indicator for the water status in the whole plant revealing stress if the water supply is reduced. The analysis of dynamic aspects of water availability in plant tissues provides useful information for the understanding of the mechanistic basis of drought stress tolerance, which may lead to improved plant breeding and management practices. The determination of the water content in plant tissues during plant development has been a challenge and is currently feasible based on destructive analysis only. We present here the application of a non-invasive quantitative method to determine the volumetric water content of leaves and the ionic conductivity of the leaf juice from non-invasive microwave measurements at two different frequencies by one sensor device. A semi-open microwave cavity loaded with a ceramic dielectric resonator and a metallic lumped-element capacitor- and inductor structure was employed for non-invasive microwave measurements at 150 MHz and 2.4 Gigahertz on potato, maize, canola and wheat leaves. Three leaves detached from each plant were chosen, representing three developmental stages being representative for tissue of various age. Clear correlations between the leaf- induced resonance frequency shifts and changes of the inverse resonator quality factor at 2.4 GHz to the gravimetrically determined drying status of the leaves were found. Moreover, the ionic conductivity of Maize leaves, as determined from the ratio of the inverse quality factor and frequency shift at 150 MHz by use of cavity perturbation theory, was found to be in good agreement with direct measurements on plant juice. In conjunction with a compact battery- powered circuit board- microwave electronic module and a user-friendly software interface, this method enables rapid in-vivo water amount assessment of plants by a handheld device for potential use in the field.

Although several health and development indicators have improved significantly in Cambodia, inadequate breastfeeding and inappropriate complementary feeding practices leave many children at high risk of malnutrition during the early stages of life. In 2014, the prevalence of wasting and stunting among Cambodian children under 5 were 10% and 32%, respectively. Thus, a strong focus on improving feeding practices within the first 1000 days window to reduce child malnutrition prevalence in Cambodia is needed. This cross-sectional study assessed the current feeding practices among of women of reproductive age, pregnant women, lactating women and children less than 24 months living in six districts from Phnom Penh and two rural provinces in the North East of Cambodia. The nutritional status of pregnant women was poor, with 21.4% having a Middle Upper arm circumference below 23 cm. While breastfeeding was predominant within the first 6 months of age in every district, feeding practices of pregnant women and children were a concern, as >70% of the children were not meeting the minimum acceptable diet, and most of the women did not improve their diet during pregnancy. Inadequate nutrition during the first 1000 days is highly prevalent in Cambodia. A comprehensive national Mother, Infant and Young Child Nutrition strategy needs to be developed and operationalized to improve feeding practices of Cambodian women and children.

Objectives The United States is one of only three countries worldwide with no national policy guaranteeing paid leave to employed women who give birth. While maternity leave has been linked to improved maternal and child outcomes in international contexts, up-to-date research evidence in the U.S. context is needed to inform current policy debates on paid family leave. Methods Using data from Listening to Mothers III, a national survey of women ages 18-45 who gave birth in 2011-2012, we conducted multivariate logistic regression to predict the likelihood of outcomes related to infant health, maternal physical and mental health, and maternal health behaviors by the use and duration of paid maternity leave. Results Use of paid and unpaid leave varied significantly by race/ethnicity and household income. Women who took paid maternity leave experienced a 47% decrease in the odds of re-hospitalizing their infants (95% CI 0.3, 1.0) and a 51% decrease in the odds of being re-hospitalized themselves (95% CI 0.3, 0.9) at 21 months postpartum, compared to women taking unpaid or no leave. They also had 1.8 times the odds of doing well with exercise (95% CI 1.1, 3.0) and stress management (95% CI 1.1, 2.8), compared to women taking only unpaid leave. Conclusions for Practice Paid maternity leave significantly predicts lower odds of maternal and infant re-hospitalization and higher odds of doing well with exercise and stress management. Policies aimed at expanding access to paid maternity and family leave may contribute toward reducing socio-demographic disparities in paid leave use and its associated health benefits.

Most of today's Mission Operations Systems (MOS) rely on Ground Data System (GDS) segment to mitigate cyber security risks. Unfortunately, IT security design is done separately from the design of GDS' mission operational capabilities. This incoherent practice leaves many security vulnerabilities in the system without any notice. This paper describes a new way to system engineering MOS, to include cyber threat risk assessments throughout the MOS development cycle, without this, it is impossible to design a dependable and reliable MOS to meet today's rapid changing cyber threat environment.

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.

The FMLA is a complicated and comprehensive regulatory scheme, and it is impossible to review any but the most basic provisions in this article. The final regulations provide very detailed guidance on such issues as benefits continuation, reinstatement rights, notice requirements, and enforcement measures. Personnel policies and practices must be revised to be consistent with these final regulations, and care must be taken that leave policies do not restrict rights under the FMLA or unintentionally create expanded leave rights. In complying with the FMLA, employers must also keep in mind that there are complex interplays between the federal FMLA, state laws that provide family and medical leave, the Americans with Disabilities Act, and state workers' compensation laws, that can require expert advice depending on the particular circumstances.

To explore newly graduated nurses' (NGN) perception of their practice environment and its association with their self-assessed competence, turnover intentions and job satisfaction as work-related factors. The impact of practice environment on nurses' work is important. Positive practice environments are associated with positive organisational, nurse and patient outcomes. How this applies to NGNs needs further exploration. A cross-sectional descriptive correlation design was used. Data were collected with PES-NWI and NCS instruments from 318 Finnish registered nurses, and analysed statistically. Newly graduated nurses' perception of their practice environment was mainly positive. Most positive perceptions related to collegial nurse-physician relations, and the least positive to staffing and resource adequacy. Positive perceptions were also associated with higher professional competence, higher perceptions of quality of care and lower intentions to leave the job or profession. The findings revealed strong and significant associations between practice environment and work-related factors. Practice environment is an important element in supporting NGNs' competence, retention and job satisfaction. Nursing management should pay attention to NGNs' perceptions of their practice environment. Management's ability to create and maintain positive practice environments can foster NGNs' professional development and job satisfaction, and consequently retain them in the workforce. © 2015 John Wiley & Sons Ltd.

Leadership in Nursing Homes: Directors of Nursing Aligning Practice With Regulations.

2018-06-01

Nursing homes use team nursing, with minimal RN presence, leaving the majority of direct care to licensed practical/vocational nurses (LPNs/LVNs) and unlicensed assistive personnel (UAP), including medication aides. The current article describes challenges faced by nursing home directors of nursing (DONs) leading and managing a team nursing approach, including consideration of scope of practice, delegation and supervision regulations, and related policy implications. A secondary data analysis was performed of qualitative data from a study to develop and test DON guidelines for delegation in nursing home practice. A convenience sample (N = 29) of current or previous DONs and other nursing home leaders with knowledge and expertise in the DON role participated in in-depth, guided interviews. The findings highlight a core concern to nursing licensure policy and regulation: knowledge and practice gaps related to scope of practice and delegation and supervision among DONs, RNs, and LPNs/LVNs, as well as administrators, and the role of nursing leaders in supporting appropriate delegation practices. The findings offer directions for research and practice in addressing challenges in aligning team nursing practices with regulatory standards as well as the related gaps in knowledge among DONs, administrators, and nursing staff.

Barta, D. J.; Tibbitts, T. W.

1986-01-01

The young developing leaves of 20-day-old lettuce plants (Lactuca sativa L. 'Buttercrunch') were enclosed by aluminized polyethylene sheaths to decrease transpiration and reduce Ca transport. The plants were grown in recirculating solution culture system using a modified half-strength Hoagland's solution under cool-white fluorescent lamps with a photosynthetic photon flux of 350 micromoles s-1 m-2 in a 16:8-hr (light:dark) period. Air temperature and humidity were 20 degrees C and 65%, respectively. After 4 days of enclosure, 53% of the inner leavers (leaves one to 3 cm in length) were tipburned. After the same period, less than 1% of the inner leaves on control plants were tipburned. The concentration of Ca in enclosed inner leaves was 0.63 mg g-1 dry weight, compared to 1.48 mg g-1 dry weight in inner leaves that were not enclosed. The Ca concentration in transpiring outer leaves of all plants was 9.9 mg g-1 dry weight. The Mg concentration in enclosed inner leaves was 2.25 mg g-1 dry weight, compared to 2.34 mg g-1 dry weight in inner leaves that were not enclosed. This research documents that enclosures of leaves at the growing point, as would occur with normal head development, is sufficient to create a limiting concentration of Ca in the enclosed tissue and encourage tipburn development.

Leaves of Crateva adansonii DC (Capparidaceae), a small bush found in Togo, are widely used in traditional medicine to cure infectious abscesses. Traditional healers of Lomé harvest only budding leaves early in the morning, in specific area in order to prepare their drugs. The main goal was to validate the ancestral picking practices, and to assess the activity of C. adansonii medicine towards infectious abscesses. A phytochemical screening of various C. adansonii leaf samples was performed using an original HPTLC-densitometry protocol and major flavonoids were identified and quantified. C. adansonii samples were collected in different neighborhoods of Lomé, at different harvesting-times and at different ages. Radical scavenging capacity, using DPPH assay, was used to quickly screen all extracts. Extracts were tested for anti-Staphylococcus aureus activity and anti-inflammatory effect on human primary keratinocytes infected by S. aureus. IL6, IL8 and TNFα expression and production were assessed by RT-PCR and ELISA assays. Using antioxidant activity as selection criteria, optimal extracts were obtained with budding leaves, collected at 5:00am in Djidjolé neighborhood. This extract showed the strongest anti-inflammatory effect on S. aureus-infected keratinocytes by reducing IL6, IL8 and TNFα expression and production. None of the extracts inhibited the growth of S. aureus. Those results validate the traditional practices and the potential of C. adansonii as anti-inflammatory drug. Our findings suggest that traditional healers should add to C. adansonii leaves an antibacterial plant of Togo Pharmacopeia, in order to improve abscess healing.

2016-07-01

To better understand the roles of leaves at different stem positions during plant development, we measured the physiological properties of leaves 1-4 on maize seedling stems, and performed a proteomics study to investigate the differences in protein expression in the four leaves using two-dimensional difference gel electrophoresis and tandem mass spectrometry in conjunction with database searching. A total of 167 significantly differentially expressed protein spots were found and identified. Of these, 35% are involved in photosynthesis. By further analysis of the data, we speculated that in leaf 1 the seedling has started to transition from a heterotroph to an autotroph, development of leaf 2 is the time at which the seedling fully transitions from a heterotroph to an autotroph, and leaf maturity was reached only with fully expanded leaves 3 and 4, although there were still some protein expression differences in the two leaves. These results suggest that the different leaves make different contributions to maize seedling growth via modulation of the expression of the photosynthetic proteins. Together, these results provide insight into the roles of the different maize leaves as the plant develops from a heterotroph to an autotroph. Copyright © 2016 Elsevier GmbH. All rights reserved.

Background The popularity of complementary and alternative medicine (CAM) has led to a growing amount of research in this area. All the same little is known about the effects of these special treatments in every-day practice of primary care, delivered by general practitioners within the health insurance system. From 1994 to 2000 more than 20 German Company health insurances initiated the first model project on CAM according to the German social law. Aim of this contribution is to investigate the effectiveness of multi-modal CAM on chronic diseases within primary health care. Methods A long-term prospective intermittent study was conducted including 44 CAM practitioners and 1221 self-selected chronically ill patients (64% women) of whom 441 were employed. Main outcome measure is sick-leave, controlled for secular trends and regression-to-the mean and self-perceived health status. Results Sick-leave per year of 441 patients at work increased from 22 (SD ± 45.2) to 31 (± 61.0) days within three years prior to intervention, and decreased to 24 (± 55.6) in the second year of treatment, sustaining at this level in the following two years. Detailed statistical analysis show that this development exceeds secular trends and the regression-toward-the-mean effect. Sick-leave reduction was corroborated by data on self-reported improvement of patients' health status. Conclusion Results of this longterm observational study show a reduction of sick leave in chronically ill patients after a complex multimodal CAM intervention. However, as this is an uncontrolled observational study efficacy of any specific CAM treatment can not be proven. The results might indicate an general effectiveness of CAM in primary care, worthwhile further investigations. Future studies should identify the most suitable patients for CAM practices, the most appropriate and safe treatments, provide information on the magnitude of the effects to facilitate subsequent definitive randomised controlled studies that will help to position complementary and alternative medicine in health care.

Riparian buffers provide improved protection for water quality and biota, and narrow, fixed-width buffers of native vegetation along streams have been used to mitigate the effects of forest harvest at least since the 1960s. The practice of leaving unmanaged strips of vegetation along water courses in agricultural lands had been used before the 1960s in southern Europe...

Costs and prevention of patient defection.

Clarke, R N

2001-01-01

Although other industries have recognized that increased customer loyalty brings increased revenues and profitability, few medical practices have sought even to measure patient retention or loyalty. When patients leave a practice, new patients must be attracted to replace lost ones at significant cost, often invisible to and underestimated by physicians. Understanding the lifetime value of a patient may be one route that leads to better patient loyalty practices and enhanced profitability.

Patients who leave the hospital against medical advice: the role of the psychiatric consultant.

Previous studies have identified characteristics of patients who threaten to leave non-psychiatric units against medical advice, but few have described the role of the psychiatric consultant in the patient's decision. This study compared the medical records of 31 patients who threatened to leave the hospital against medical advice (AMA) and who were seen in consultation with the records of AMA-discharged patients who were not seen by a psychiatric consultant. Most patients who received consultations remained hospitalized or were discharged in regular fashion. Those seen soon after admission were most likely to stay. Patients were more likely to remain hospitalized if the consultant's recommendations had a practical, rather than a psychological, orientation.

Bidirectional Reflectance Modeling of Non-homogeneous Plant Canopies

Norman, J. M. (Principal Investigator)

1985-01-01

The objective of this research is to develop a 3-dimensional radiative transfer model for predicting the bidirectional reflectance distribution function (BRDF) for heterogeneous vegetation canopies. The model (named BIGAR) considers the angular distribution of leaves, leaf area index, the location and size of individual subcanopies such as widely spaced rows or trees, spectral and directional properties of leaves, multiple scattering, solar position and sky condition, and characteristics of the soil. The model relates canopy biophysical attributes to down-looking radiation measurements for nadir and off-nadir viewing angles. Therefore, inversion of this model, which is difficult but practical should provide surface biophysical pattern; a fundamental goal of remote sensing. Such a model also will help to evaluate atmospheric limitations to satellite remote sensing by providing a good surface boundary condition for many different kinds of canopies. Furthermore, this model can relate estimates of nadir reflectance, which is approximated by most satellites, to hemispherical reflectance, which is necessary in the energy budget of vegetated surfaces.

Sucrose-metabolizing enzymes in plant leaves have hitherto been investigated mainly in temperate plants, and rarely conducted in tandem with gene expression and sugar analysis. Here, we investigated the sugar content, gene expression, and the activity of sucrose-metabolizing enzymes in the leaves of Hevea brasiliensis, a tropical tree widely cultivated for natural rubber. Sucrose, fructose and glucose were the major sugars detected in Hevea leaves at four developmental stages (I to IV), with starch and quebrachitol as minor saccharides. Fructose and glucose contents increased until stage III, but decreased strongly at stage IV (mature leaves). On the other hand, sucrose increased continuously throughout leaf development. Activities of all sucrose-cleaving enzymes decreased markedly at maturation, consistent with transcript decline for most of their encoding genes. Activity of sucrose phosphate synthase (SPS) was low in spite of its high transcript levels at maturation. Hence, the high sucrose content in mature leaves was not due to increased sucrose-synthesizing activity, but more to the decline in sucrose cleavage. Gene expression and activities of sucrose-metabolizing enzymes in Hevea leaves showed striking differences compared with other plants. Unlike in most other species where vacuolar invertase predominates in sucrose cleavage in developing leaves, cytoplasmic invertase and sucrose synthase (cleavage direction) also featured prominently in Hevea. Whereas SPS is normally responsible for sucrose synthesis in plant leaves, sucrose synthase (synthesis direction) was comparable or higher than that of SPS in Hevea leaves. Mature Hevea leaves had an unusually high sucrose:starch ratio of about 11, the highest reported to date in plants. PMID:29449852

Separate localization of light signal perception for sun or shade type chloroplast and palisade tissue differentiation in Chenopodium album.

PubMed

Yano, S; Terashima, I

2001-12-01

Physiological and ecological characteristics of sun and shade leaves have been compared in detail, but their developmental processes, in particular their light sensory mechanisms, are still unknown. This study compares the development of sun and shade leaves of Chenopodium album L., paying special attention to the light sensory site. We hypothesized that mature leaves sense the light environment, and that this information determines anatomy of new leaves. To examine this hypothesis, we shaded plants partially. In the low-light apex treatment (LA), the shoot apex with developing leaves was covered by a cap made of a shading screen and received photosynthetically active photon flux density (PPFD) of 60 micromol m(-2 )s(-1), while the remaining mature leaves were exposed to 360 micromol m(-2 )s(-1). In the high-light apex treatment (HA), the apex was exposed while the mature leaves were covered by a shade screen. After these treatments for 6 d, we analyzed leaf anatomy and chloroplast ultrastructure. The anatomy of LA leaves with a two-layered palisade tissue was similar to that of sun leaves, while their chloroplasts were shade-type with thick grana. The anatomy of HA leaves and shade leaves was similar and both had one-layered palisade tissue, while chloroplasts of HA leaves were sun-type having thin grana. These results clearly demonstrate that new leaves differentiate depending on the light environment of mature leaves, while chloroplasts differentiate depending on the local light environment.

Platycladus orientalis leaves: a systemic review on botany, phytochemistry and pharmacology.

2014-01-01

Platycladus orientalis leaves (Cebaiye) have been used for thousands of years as traditional Chinese medicine (TCM). According to the theory of TCM, they are categorized as a blood-cooling and hematostatic herb. In clinical practice, they were usually prescribed with heat-clearing herbs to reinforce the efficacy of hemostasis. The review provides the up-to-date information from 1980 to present that is available on the botany, processing research, phytochemistry, pharmacology and toxicology of the leaves. The information is collected from scientific journals, books, theses and reports via library and electronic search (Google Scholar, Pubmed and CNKI). Through literature reports, we can find that the leaves show a wide spectrum of pharmacological activities, such as anti-inflammatory, antioxidant, antimicrobial, disinsection, anticancer, diuretic, hair growth-promoting, neuroprotective and antifibrotic activities. Diterpene and flavonoids would be active constituents in P. orientalis leaves. Many studies have provided evidence for various traditional uses. However, there is a great need for additional studies to elucidate the mechanism of blood-cooling and hematostatic activity of the leaves. Therefore, the present review on the botany, traditional uses, phytochemistry and toxicity has provided preliminary information for further studies of this herb.

The development and reproductive potential of Spodoptera eridania (Stoll, 1782) (Lepidoptera, Noctuidae) was compared on natural and artificial diets. Its biology was determined under laboratory conditions, providing an artificial diet, leaves of white clover and the peach cultivar 'Chimarrita' and fruits and leaves of the apple cultivar 'Gala'. Larvae of S. eridania could not complete their biological cycle when fed on apple fruits or peach leaves. The artificial diet provided the shortest development time, with a cycle of 28.5±0.14 days from egg to adult and 37.3% total viability. Apple leaves led to a longer development time from egg to adult (62.8±1.22 days) and lower total viability (23%) and white clover provided the highest total viability (54.3%). The results showed that S. eridania can use white clover and apple leaves to develop normally in apple orchards. The reduction of food sources such as white clover used by the larvae results in infestation and damage to fruits from "test bites".

It has been reported by some studies that the desire to be involved in decisions concerning one's healthcare especially with regard to obtaining informed consent is related to educational status. The purpose of this study, therefore, is to assess the influence of educational status on attitude towards informed consent practice in three south-eastern Nigerian communities. Responses from consenting adult participants from three randomly selected communities in Enugu State, southeast Nigeria were obtained using self-/interviewer-administered questionnaire. There were 2545 respondents (1508 males and 1037 females) with an age range of 18 to 65 years. More than 70% were aged 40 years and below and 28.4% were married. More than 70% of the respondents irrespective of educational status will not leave all decisions about their healthcare to the doctor. A lower proportion of those with no formal education (18.5%) will leave this entire decision-making process in the hands of the doctor compared to those with tertiary education (21.9%). On being informed of all that could go wrong with a procedure, 61.5% of those with no formal education would consider the doctor unsafe and incompetent while 64.2% of those with tertiary education would feel confident about the doctor. More than 85% of those with tertiary education would prefer consent to be obtained by the doctor who will carry out the procedure as against 33.8% of those with no formal education. Approximately 70% of those who had tertiary education indicated that informed consent was necessary for procedures on children, while the greater number of those with primary (64.4%) and no formal education (76.4%) indicated that informed consent was not necessary for procedures on children. Inability to understand the information was the most frequent specific response among those without formal education on why they would leave all the decisions to the doctor. The study showed that knowledge of the informed consent practice increased with level of educational attainment but most of the participants irrespective of educational status would want to be involved in decisions about their healthcare. This knowledge will be helpful to healthcare providers in obtaining informed consent.

A fingerprint analysis method was developed for Ginkgo biloba leaves and was successfully used for quality evaluation of related health foods by HPLC with electrospray ionization MS. Fifteen samples of G. biloba leaves, which were collected from 15 different locations in China, were analyzed and identified in this study. By both peak analysis and similarity analysis of the fingerprint chromatograms, variation of constituents was easily observed in the leaves from different sources. By comparison with batches of authentic leaves, the authenticity, and quality consistency of related health foods in different matrixes were effectively estimated. It is important to mention that studying a wide range of authentic leaves from various habitats made the quality evaluation of commercial products more convincing and reasonable. The fingerprint-based strategy of the developed method should provide improved QC of G. biloba leaves and products.

When the group practice breaks up: a qualitative study

PubMed Central

2013-01-01

Background Group practices are increasingly common for primary care physicians worldwide. Although breakups are likely to happen frequently within group practices, their process has not been studied to date. The aims of this study were therefore to explore the reasons for breakups of group practices of general practitioners and to describe the associated feelings. Methods We conducted a qualitative study consisting of in-depth interviews of 21 general practitioners and one secretary from past group practices in the Rhône-Alpes region, France, who experienced a breakup. Results When getting started in group practice for the first time, young doctors did not feel ready and supported, and did not necessarily share the same expectations as their partners. The reasons for the breakups involved imbalances within the groups, contrasting working and management styles, and breakdowns in communication. The breakup process often generated long-persistent feelings of suffering and failure for almost every partner who experienced a breakup, particularly for the partner who was leaving. Conclusions Weakening factors exist from the very beginning of a partnership, and problems are likely to increase at every change or event occurring in the group. We provide several recommendations, including fair management, a shared project based on a precise contract, the consultation of third parties as necessary and, in the worst case scenario, leaving the group practice in time.

Transcriptome Analysis Comparison of Lipid Biosynthesis in the Leaves and Developing Seeds of Brassica napus

2015-01-01

Brassica napus seed is a lipid storage organ containing approximately 40% oil, while its leaves contain many kinds of lipids for many biological roles, but the overall amounts are less than in seeds. Thus, lipid biosynthesis in the developing seeds and the leaves is strictly regulated which results the final difference of lipids. However, there are few reports about the molecular mechanism controlling the difference in lipid biosynthesis between developing seeds and leaves. In this study, we tried to uncover this mechanism by analyzing the transcriptome data for lipid biosynthesis. The transcriptome data were de novo assembled and a total of 47216 unigenes were obtained, which had an N50 length and median of 1271 and 755 bp, respectively. Among these unigenes, 36368 (about 77.02%) were annotated and there were 109 up-regulated unigenes and 72 down-regulated unigenes in the developing seeds lipid synthetic pathway after comparing with leaves. In the oleic acid pathway, 23 unigenes were up-regulated and four unigenes were down-regulated. During triacylglycerol (TAG) synthesis, the key unigenes were all up-regulated, such as phosphatidate phosphatase and diacylglycerol O-acyltransferase. During palmitic acid, palmitoleic acid, stearic acid, linoleic acid and linolenic acid synthesis in leaves, the unigenes were nearly all up-regulated, which indicated that the biosynthesis of these particular fatty acids were more important in leaves. In the developing seeds, almost all the unigenes in the ABI3VP1, RKD, CPP, E2F-DP, GRF, JUMONJI, MYB-related, PHD and REM transcript factorfamilies were up-regulated, which helped us to discern the regulation mechanism underlying lipid biosynthesis. The differential up/down-regulation of the genes and TFs involved in lipid biosynthesis in developing seeds and leaves provided direct evidence that allowed us to map the network that regulates lipid biosynthesis, and the identification of new TFs that are up-regulated in developing seeds will help us to further elucidate the lipids biosynthesis pathway in developing seeds and leaves.

Sugars are the most abundant organic compounds produced by plants, and can be used to build carbon skeletons and generate energy. The sugar accumulation 1 (OsSAC1) gene encodes a protein with an unknown function that exhibits four N-terminal transmembrane regions and two conserved domains of unknown function, DUF4220 and DUF594. OsSAC1 was found to be poorly and specifically expressed at the bottoms of young leaves and in the developing leaf sheaths. Subcellular location results showed that OsSAC1 was co-localized with ER:mCherry and targeted the endoplasmic reticulum (ER). OsSAC1 has been found to affect sugar partitioning in rice (Oryza sativa). I2/KI starch staining, ultrastructure observations and starch content measurements indicated that more and larger starch granules accumulated in ossac1 source leaves than in wild-type (WT) source leaves. Additionally, higher sucrose and glucose concentrations accumulated in the ossac1 source leaves than in WT source leaves, whereas lower sucrose and glucose concentrations were observed in the ossac1 young leaves and developing leaf sheaths than in those of the WT. Much greater expression of OsAGPL1 and OsAGPS1 (responsible for starch synthesis) and significantly less expression of OscFBP1, OscFBP2, OsSPS1 and OsSPS11 (responsible for sucrose synthesis) and OsSWEET11, OsSWEET14 and OsSUT1 (responsible for sucrose loading) occurred in ossac1 source leaves than in WT source leaves. A greater amount of the rice plasmodesmatal negative regulator OsGSD1 was detected in ossac1 young leaves and developing leaf sheaths than in those of the WT. These results suggest that ER-targeted OsSAC1 may indirectly regulate sugar partitioning in carbon-demanding young leaves and developing leaf sheaths.

2013-01-27

Policy initiatives to improve retention of the rural health workforce have relied primarily on evidence for rural doctors, most of whom practice under a private business model. Much of the literature for rural allied health (AH) workforce focuses on the public sector. The AH professions are diverse, with mixed public, private or combined practice settings. This study explores sector differences in factors affecting retention of rural AH professionals. This study compared respondents from the 2008 Rural Allied Health Workforce (RAHW) survey recruiting all AH professionals in rural New South Wales. Comparisons between public (n = 833) and private (n = 756) groups were undertaken using Chi square analysis to measure association for demographics, job satisfaction and intention to leave. The final section of the RAHW survey comprised 33 questions relating to retention. A factor analysis was conducted for each cohort. Factor reliability was assessed and retained factors were included in a binary logistic regression analysis for each cohort predicting intention to leave. Six factors were identified: professional isolation, participation in community, clinical demand, taking time away from work, resources and 'specialist generalist' work. Factors differed slightly between groups. A seventh factor (management) was present only in the public cohort. Gender was not a significant predictor of intention to leave. Age group was the strongest predictor of intention to leave with younger and older groups being significantly more likely to leave than middle aged.In univariate logistic analysis (after adjusting for age group), the ability to get away from work did not predict intention to leave in either group. In multivariate analysis, high clinical demand predicted intention to leave in both the public (OR = 1.40, 95% CI = 1.08, 1.83) and private (OR = 1.61, 95% CI = 1.15, 2.25) cohorts. Professional isolation (OR = 1.39. 95% CI = 1.11, 1.75) and Participation in community (OR = 1.57, 95% CI = 1.13, 2.19) also contributed to the model in the public cohort. This paper demonstrates differences between those working in public versus private sectors and suggests that effectiveness of policy initiatives may be improved through better targeting.

The evolution, morphology, and development of fern leaves

PubMed Central

Vasco, Alejandra; Moran, Robbin C.; Ambrose, Barbara A.

2013-01-01

Leaves are lateral determinate structures formed in a predictable sequence (phyllotaxy) on the flanks of an indeterminate shoot apical meristem. The origin and evolution of leaves in vascular plants has been widely debated. Being the main conspicuous organ of nearly all vascular plants and often easy to recognize as such, it seems surprising that leaves have had multiple origins. For decades, morphologists, anatomists, paleobotanists, and systematists have contributed data to this debate. More recently, molecular genetic studies have provided insight into leaf evolution and development mainly within angiosperms and, to a lesser extent, lycophytes. There has been recent interest in extending leaf evolutionary developmental studies to other species and lineages, particularly in lycophytes and ferns. Therefore, a review of fern leaf morphology, evolution and development is timely. Here we discuss the theories of leaf evolution in ferns, morphology, and diversity of fern leaves, and experimental results of fern leaf development. We summarize what is known about the molecular genetics of fern leaf development and what future studies might tell us about the evolution of fern leaf development. PMID:24027574

Changes in photosynthesis, mesophyll conductance to CO2, and isoprenoid emissions in Populus nigra plants exposed to excess nickel.

2011-05-01

Poplar (Populus nigra) plants were grown hydroponically with 30 and 200 μM Ni (Ni30 and Ni200). Photosynthesis limitations and isoprenoid emissions were investigated in two leaf types (mature and developing). Ni stress significantly decreased photosynthesis, and this effect depended on the leaf Ni content, which was lower in mature than in developing leaves. The main limitations to photosynthesis were attributed to mesophyll conductance and metabolism impairment. In Ni-stressed developing leaves, isoprene emission was significantly stimulated. We attribute such stimulation to the lower chloroplastic [CO2] than in control leaves. However chloroplastic [CO2] did not control isoprene emission in mature leaves. Ni stress induced the emission of cis-β-ocimene in mature leaves, and of linalool in both leaf types. Induced biosynthesis and emission of isoprenoids reveal the onset of antioxidant processes that may also contribute to reduce Ni stress, especially in mature poplar leaves.

Graduates of specialized BSW child welfare education programs are more likely to be retained after two years of service in the agency, but many leave at the four year mark. Two studies explored possible reasons for departure at this time. The first study found that graduates of specialized child welfare programs were significantly more likely to engage in best practices in nine areas than workers from other fields. Thus, frustration with practice skill was ruled out as a cause. The second qualitative study found that poor supervision, lack of coworker support, and organizational stress among other variables prompted these high-functioning workers to leave the agency. Suggestions for innovative interventions to enhance retention at this critical juncture are included.

Dried-leaf Artemisia annua: A practical malaria therapeutic for developing countries?

PubMed Central

Weathers, Pamela J; Towler, Melissa; Hassanali, Ahmed; Lutgen, Pierre; Engeu, Patrick Ogwang

2015-01-01

Artemisinin from the plant Artemisia annua (A. annua) L, and used as artemisinin combination therapy (ACT), is the current best therapeutic for treating malaria, a disease that hits children and adults especially in developing countries. Traditionally, A. annua was used by the Chinese as a tea to treat “fever”. More recently, investigators have shown that tea infusions and oral consumption of the dried leaves of the plant have prophylactic and therapeutic efficacy. The presence of a complex matrix of chemicals within the leaves seems to enhance both the bioavailability and efficacy of artemisinin. Although about 1000-fold less potent than artemisinin in their antiplasmodial activity, these plant chemicals are mainly small molecules that include other artemisinic compounds, terpenes (mainly mono and sesqui), flavonoids, and polyphenolic acids. In addition, polysaccharide constituents of A. annua may enhance bioavailability of artemisinin. Rodent pharmacokinetics showed longer T1/2 and Tmax and greater Cmax and AUC in Plasmodium chabaudi-infected mice treated with A. annua dried leaves than in healthy mice. Pharmacokinetics of deoxyartemisinin, a liver metabolite of artemisinin, was more inhibited in infected than in healthy mice. In healthy mice, artemisinin serum levels were > 40-fold greater in dried leaf fed mice than those fed with pure artemisinin. Human trial data showed that when delivered as dried leaves, 40-fold less artemisinin was required to obtain a therapeutic response compared to pure artemisinin. ACTs are still unaffordable for many malaria patients, and cost estimates for A. annua dried leaf tablet production are orders of magnitude less than for ACT, despite improvements in the production capacity. Considering that for > 2000 years this plant was used in traditional Chinese medicine for treatment of fever with no apparent appearance of artemisinin drug resistance, the evidence argues for inclusion of affordable A. annua dried leaf tablets into the arsenal of drugs to combat malaria and other artemisinin-susceptible diseases.

The purpose of the present study was to investigate the potential associations of binge drinking detected at the exit of nightclubs and risk behaviors and alcohol effects just after leaving the venue in a representative sample of Brazilian nightclub patrons according to sex. For this purpose, a portal survey study called Balada com Ciência was conducted in 2013 in the megacity of São Paulo, Brazil, using a two-stage cluster sampling survey design. Individual-level data were collected in 2422 subjects at the entrance and 1822 subjects at the exit of 31 nightclubs, and breath alcohol concentration (BrAC) was measured using a breathalyzer. The following day, 1222 patrons answered an online follow-up survey that included questions about risk behaviors and alcohol effects practiced just after leaving the nightclub. Weighted logistic regressions were used to analyze binge drinking associated with risk behaviors by sex. For both sexes, the most prevalent risk behaviors practiced after leaving a nightclub were drinking and driving (men=27.9%; women=20.4%), the use of illicit drugs (men=15.8%; women=9.4%) and risky sexual behavior (men=11.4%; women=6.8%). The practice of binge drinking increased the behavior of illicit drug use after leaving the nightclub by 2.54 times [95% CI: 1.26-5.09] among men who drank and increased the risk of an episode of new alcohol use by 5.80 times [95% CI: 1.50-22.44] among women who drank. Alcoholic blackouts were more prevalent among men [OR=8.92; 95% CI: 3.83-20.80] and women [OR= 5.31; 95% CI: 1.68-16.84] whose BrAC was equivalent to binge drinking compared with patrons with a lower BrAC. Public policies aiming to reduce patrons’ BrAC at the exit of nightclubs, such as staff training in responsible beverage service and legislation to prevent alcohol sales to drunk individuals, would be useful to protect patrons from the risk behaviors associated with binge drinking in nightclubs.

To identify factors influencing general practitioners' (GPs') decisions about whether or not to remain in direct patient care in general practice and what might help to retain them in that role. Qualitative, in-depth, individual interviews exploring factors related to GPs leaving, remaining in and returning to direct patient care. South West England, UK. 41 GPs: 7 retired; 8 intending to take early retirement; 11 who were on or intending to take a career break; 9 aged under 50 years who had left or were intending to leave direct patient care and 6 who were not intending to leave or to take a career break. Plus 19 stakeholders from a range of primary care-related professional organisations and roles. Reasons for leaving direct patient care were complex and based on a range of job-related and individual factors. Three key themes underpinned the interviewed GPs' thinking and rationale: issues relating to their personal and professional identity and the perceived value of general practice-based care within the healthcare system; concerns regarding fear and risk, for example, in respect of medical litigation and managing administrative challenges within the context of increasingly complex care pathways and environments; and issues around choice and volition in respect of personal social, financial, domestic and professional considerations. These themes provide increased understanding of the lived experiences of working in today's National Health Service for this group of GPs. Future policies and strategies aimed at retaining GPs in direct patient care should clarify the role and expectations of general practice and align with GPs' perception of their own roles and identity; demonstrate to GPs that they are valued and listened to in planning delivery of the UK healthcare; target GPs' concerns regarding fear and risk, seeking to reduce these to manageable levels and give GPs viable options to support them to remain in direct patient care. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Hospitals are purchasing physician practices at a rate not seen since the 1990s, and the action is widespread. Doctors all over the country--in practices large and small, successful and struggling--are jumping at the chance to leave the complexity, business risks, and stagnant economics of private practice for the perceived security of a larger organization. This article examines the trend and offers suggestions for physicians to determine whether or not selling is the right move.

Clerkship maturity: Does the idea of training clinical skills work?

Stosch, Christoph; Joachim, Alexander; Ascher, Johannes

2011-01-01

Background: With the reformed curriculum “4C”, the Medical Faculty of the University of Cologne has started to systematically plan practical skills training, for which Clerkship Maturity is the first step. The key guidelines along which the curriculum was development were developed by experts. This approach has now been validated. Materials and methods: Both students and teachers were asked to fill in a questionnaire regarding preclinical practical skills training to confirm the concept of Clerkship Maturity. Results and discussion: The Cologne training program Clerkship Maturity can be validated empirically overall through the activities of the students awaiting the clerkship framework and through the evaluation by the medical staff providing the training. The subjective ratings of the advantages of the training by the students leave room for improvement. Apart from minor improvements to the program, the most likely solution providing sustainable results will involve an over-regional strategy for establishing skills training planned as part of the curriculum.

2004-01-01

The authors sought to describe risk indicators of long-term sick leave during pregnancy among hospital employees. A register-based study was undertaken of 4,852 female hospital employees aged 20-45 years from the second largest hospital in Denmark during 1995-99 based on job titles, working time, sick leave, and births combined with a survey among a total of 773 women who had been pregnant during their employment (response rate 85%). Altogether 236 (31%) were on sick leave for at least 10% of their scheduled work time during their latest pregnancy and 169 (22%) had been absent at least 20% of the time. The pregnant women had an average sickness absence of 6.1 days per month, non-pregnant women 0.95 days per month. Sick leave was more frequent in late than in early gestation. Women employed as nursing aides or hospital orderlies, launderers, and nurses had more sick leave days than other hospital employees. Part-time work, previous sickness absence not related to pregnancy, and previous chronic back pain were risk factors for long-term sick leave as were much walking or standing, long working days, high work level, little practical support from supervisors and colleagues, low job control, much lifting and night or shift work. Sick leave was unrelated to family size, support from the family and number of working years. Long-term sick leave during pregnancy was frequent and to some extent predictable. Efforts should be made to organize work for pregnant women in a manner that optimizes their health and well-being.

Development of an Optical Device to Investigatechlorophyll Content of Tomato Leaves

NASA Astrophysics Data System (ADS)

Cui, Di; Li, Minzan; Li, Xiuhua

Chlorophyll content is an important indication for evaluating crop growth status and predicting crop yield. The NDVI (Normalized Difference Vegetation Index) is commonly used as an indicator in practical crop healthy monitoring. Hence, a spectroscopy-based device for indirectly measuring crop growth conditions in terms of NDVI is developed. This device consists of four channels: two are designed to measure the intensity of the sunlight and the other two are used to measure the reflected light from the crop canopy at the same time. An electronic control unit was designed to control the sensing and data recording processes, as well as to calculate the NDVI based on the sensed data. The measurable two wavelengths are 610 nm and 1220 nm. A series validation tests, comparing the measurement result against spectroradiometer readings, are conducted to evaluate the performance of the device. Leaf samples are collected to measure chlorophyll contents in laboratory. The correlation coefficient between the NDVI readings from the developed device and the chlorophyll content data measured by the UV-VIS Spectrophotometer reaches 0.81, which shows that the device can be used in practical crop management.

Objective The primary objective was to investigate how physicians’ gender and level of experience affects the rate and length of sick-leave certificate prescription. The secondary objective was to study the physicians’ gender and professional experience in relation to the diagnoses on the certificates. Design Retrospective, cross-sectional study of computerized medical records from 24 health care centres in 2005. Setting Primary care in Sweden. Subjects Primary care physicians (n = 589) and patients (n = 88 780) aged 18–64 years. Main outcome measures Rate and duration of sick leave certified by different categories of physicians and for different diagnoses and gender of patients. Results Sick leave was certified in 9.0% (musculoskeletal (3%) and psychiatric (2.3%) diagnoses were most common) of all contacts and the mean duration was 32.2 days. Overall there was no difference between male and female physicians in the sick-leave certification prescription rate (9.1% vs. 9.0%) or duration of sick leave (32.1 vs. 32.6 days). The duration of sick leave was associated with the physician's level of professional experience in general practice (GPs (Distriktläkare) 37, GP trainees (ST-läkare) 26, interns (AT-läkare) 20 and locum (vikarier) 19 days, p < 0.001). Conclusion Contrary to earlier studies we found no difference in sick-leave certification prescription rate and length between male and female physicians. PMID:22348513

Examining the Evolution of Paid Parental Leave.

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.

A paradigm is an accepted world view. If we do not continually question our paradigm then wider trends and movements will overtake the discipline leaving it ill adapted to future challenges. This Special Issue is an opportunity to keep systems thinking at the forefront of ergonomics theory and practice. Systems thinking prompts us to ask whether ergonomics, as a discipline, has been too timid? Too preoccupied with the resolution of immediate problems with industrial-age methods when, approaching fast, are developments which could render these operating assumptions an irrelevance. Practical case studies are presented to show how abstract systems problems can be tackled head-on to deliver highly innovative and cost-effective insights. The strategic direction of the discipline foregrounds high-quality systems problems. These are something the discipline is well able to respond to provided that the appropriate operating paradigms are selected. Practitioner Summary: High-quality systems problems are the future of the discipline. How do we convert obtuse sounding systems concepts into practical interventions? In this paper, the essence of systems thinking is distilled and practical case studies used to demonstrate the benefits of this new paradigm.

Change the curriculum--or transform the conditions of practice?

PubMed

Clare, J

1993-08-01

This paper explores the notion that contemporary teaching practices reinforce and maintain the legitimacy of traditional relations of power between teachers and students of nursing. Nurse teachers and clinicians have socially constructed and legitimated power over students which acts to constrain the development of critical consciousness. Student-centred learning packages and strategies such as problem-solving, questioning and dialogue may give the impression of student empowerment while leaving the authoritarian nature of teacher-student relationships intact. Furthermore nursing education is premised on the belief that 'real' learning takes place in the classroom (where teaching occurs) and is consolidated by practice (where nursing occurs). This situation creates a major dilemma for all teachers since the contradictions between classroom knowledge and experiential clinical knowledge are seldom officially recognised. The rhetoric of critical social science however, suggests that emancipation and empowerment of teachers and students would follow their enlightenment as to the nature of these contradictions. This assumption discounts the ways in which hegemonic ideology shapes the consciousness of nurses to accept dominant views of what constitutes professional practice or legitimate knowledge and how that may be obtained.

The DCL gene of tomato is required for chloroplast development and palisade cell morphogenesis in leaves.

PubMed

Keddie, J S; Carroll, B; Jones, J D; Gruissem, W

1996-08-15

The defective chloroplasts and leaves-mutable (dcl-m) mutation of tomato was identified in a Ds mutagenesis screen. This unstable mutation affects both chloroplast development and palisade cell morphogenesis in leaves. Mutant plants are clonally variegated as a result of somatic excision of Ds and have albino leaves with green sectors. Leaf midribs and stems are light green with sectors of dark green tissue but fruit and petals are wild-type in appearance. Within dark green sectors of dcl-m leaves, palisade cells are normal, whereas in albino areas of dcl-m leaves, palisade cells do not expand to become their characteristic columnar shape. The development of chloroplasts from proplastids in albino areas is apparently blocked at an early stage. DCL was cloned using Ds as a tag and encodes a novel protein of approximately 25 kDa, containing a chloroplast transit peptide and an acidic alpha-helical region. DCL protein was imported into chloroplasts in vitro and processed to a mature form. Because of the ubiquitous expression of DCL and the proplastid-like appearance of dcl-affected plastids, the DCL protein may regulate a basic and universal function of the plastid. The novel dcl-m phenotype suggests that chloroplast development is required for correct palisade cell morphogenesis during leaf development.

The strongest predictor of nurse job dissatisfaction and intent to leave is that of stress in the practice environment. Good communication, control over practice, decision making at the bedside, teamwork, and nurse empowerment have been found to increase nurse satisfaction and decrease turnover. In this article we share our experience of developing a rapid-design process to change the approach to performance improvement so as to increase engagement, empowerment, effectiveness, and the quality of the professional practice environment. Meal and non-meal breaks were identified as the target area for improvement. Qualitative and quantitative data support the success of this project. We begin this article with a review of literature related to work environment and retention and a presentation of the frameworks used to improve the work environment, specifically Maslow's theory of the Hierarchy of Inborn Needs and the National Database of Nursing Quality Indicators Survey. We then describe our performance improvement project and share our conclusion and recommendations.

Planning for life after orthopaedics.

PubMed

Barr, Joseph S; McCaslin, Michael J; Hinds, Cynthia K

2014-01-01

The word retirement is going out of fashion. Many orthopaedic surgeons want to work in some capacity when they stop performing surgery. Making a smooth transition from a busy orthopaedic practice to alternative work demands advanced planning. The surgeon must consider personal issues that involve how to use human capital (his or her accumulated knowledge and experience). New ventures, hobbies, travel, and spending time with family and friends are some possibilities. Plans for slowing down or leaving the practice should be discussed and agreed on well ahead of time. Agreements for buyouts may be difficult to work out and will require creative thinking. The solo practitioner can close the practice or hire a successor. Financial planning is perhaps the most important consideration and should be started by approximately age 40. It is recommended that the surgeon develop a portfolio of secure investments and annuities to provide adequate income for as long as is needed and then to turn the residual income to one's family, favorite charities, or other desired cause. A team of competent advisors is needed to help develop and achieve one's goals, create financial security, and provide the discipline to carry out the needed planning for life after orthopaedics.

The high cost of training and the relatively long period of training for physicians make it beneficial to stimulate physicians to retire later. Therefore, a better understanding of the link between the factors influencing the decision to retire and actual turnover would benefit policies designed to encourage later retirement. This study focuses on actual GP turnover and the determining factors for this in the Netherlands. The period 2003-2007 saw fewer GPs retiring from general practice than the period 1998-2002. In addition, GPs' retirement age was higher in 2003-2007. For these two periods, we analysed work perception, objective workload and reasons for leaving, and related these with the probability that GPs would leave general practice at an early age. In 2003, a first retrospective survey was sent to 520 self-employed GPs who had retired between 1998 and 2002. In 2008, the same survey was sent to 405 GPs who had retired between 2003 and 2007. The response rates were 60% and 54%, respectively. Analyses were done to compare work perception, objective workload, external factors and personal reasons for retiring. For both male and female GPs, work perception was different in the periods under scrutiny: both groups reported greater job satisfaction and a lower degree of emotional exhaustion in the later period, although there was no notable difference in subjective workload. The objective workload was lower in the second period. Moreover, most external factors and personal reasons that may contribute to the decision to retire were reported as less important in the second period. There was a stronger decrease in the probability that female GPs leave general practice within one year than for male GPs. This underscores the gender differences and the need for disaggregated data collection. The results of this study suggest that the decrease in the probability of GPs leaving general practice within one year and the increasing retirement age are caused by a decrease in the objective workload, a change in GPs' work perception, external factors and personal reasons. Based on the results of this study, we consider workload reduction policies are the most useful instruments to control retention and retirement.

Aroma content of fresh basil (Ocimum basilicum L.) leaves is affected by light reflected from colored mulches.

Loughrin, John H; Kasperbauer, Michael J

2003-04-09

Sweet basil (Ocimum basilicum L.) is an herb that is used to add a distinct aroma and flavor to food. Volatile compounds emitted from fully expanded fresh leaves grown in drip-irrigated plots that were covered with six colors of mulch were compared. The colors reflected a range of photosynthetic photon flux, far-red, red, and blue light from the soil surface to developing leaves. Our objective was to determine whether reflection from the different colors could influence concentrations of volatile compounds emitted from the fresh leaves. Volatile compounds were isolated by headspace sampling and quantified by gas chromatography. Twenty-six compounds were identified, of which the terpenoids linalool and 1,8-cineole comprised more than 50% of the total yield. Concentrations of volatile compounds from leaves that developed over green, blue, yellow, white, and red mulches followed the same patterns as they did for air-dried leaves of the same cultivar. However, the concentration of volatile compounds from fresh leaves was about 50-fold higher than those found in the previous study of air-dried leaves.

Despite the provision of maternity leave offered to mothers, many American women fail to take leave. We developed an evidence-based maternity leave educational tool for working women in California using participatory design. We tested its short-term efficacy with a randomized controlled trial of pregnant English-speakers (n=155). Among intervention participants exposed to the tool, 65% reported that they learned something new; 38% were motivated to seek more information; and 49% said it helped them plan their maternity leave. Among participants who delivered at ≥ 37 weeks gestation and said the tool helped them plan their leave, 89% took more than one week of prenatal leave, a significantly higher proportion than among controls who did not receive the tool (64%, p=0.049). Other findings favored trial participants, but were not statistically significant in this small sample. More intervention participants took some prenatal leave (80%) vs. controls (74%, p=0.44). Among participants who had returned to work when surveyed (n=50), mean postnatal leave uptake was on average 1 week longer for intervention participants vs. controls (13.3 vs. 12.2 weeks, p=0.54). The first-phase evaluation of this tool shows that it successfully informed women about maternity leave options, clarified complex regulations, encouraged women to seek further information and helped plan maternity leave. Compared to controls, trial participants who used the tool to plan their leave were far more likely to take prenatal leave close to term. Future evaluation of the tool when mediated by a health provider or employer is warranted.

Objectives To develop and validate a national set of best practice statements for use in post-stroke aphasia rehabilitation. Design Literature review and statement validation using the RAND/UCLA Appropriateness Method (RAM). Participants A national Community of Practice of over 250 speech pathologists, researchers, consumers and policymakers developed a framework consisting of eight areas of care in aphasia rehabilitation. This framework provided the structure for the development of a care pathway containing aphasia rehabilitation best practice statements. Nine speech pathologists with expertise in aphasia rehabilitation participated in two rounds of RAND/UCLA appropriateness ratings of the statements. Panellists consisted of researchers, service managers, clinicians and policymakers. Main outcome measures Statements that achieved a high level of agreement and an overall median score of 7–9 on a nine-point scale were rated as ‘appropriate’. Results 74 best practice statements were extracted from the literature and rated across eight areas of care (eg, receiving the right referrals, providing intervention). At the end of Round 1, 71 of the 74 statements were rated as appropriate, no statements were rated as inappropriate, and three statements were rated as uncertain. All 74 statements were then rated again in the face-to-face second round. 16 statements were added through splitting existing items or adding new statements. Seven statements were deleted leaving 83 statements. Agreement was reached for 82 of the final 83 statements. Conclusions This national set of 82 best practice statements across eight care areas for the rehabilitation of people with aphasia is the first to be validated by an expert panel. These statements form a crucial component of the Australian Aphasia Rehabilitation Pathway (AARP) (http://www.aphasiapathway.com.au) and provide the basis for more consistent implementation of evidence-based practice in stroke rehabilitation.

A qualitative study of experienced nurses' voluntary turnover: learning from their perspectives.

PubMed

Hayward, Dana; Bungay, Vicky; Wolff, Angela C; MacDonald, Valerie

2016-05-01

The purpose of this research was to critically examine the factors that contribute to turnover of experienced nurses' including their decision to leave practice settings and seek alternate nursing employment. In this study, we explore experienced nurses' decision-making processes and examine the personal and environmental factors that influenced their decision to leave. Nursing turnover remains a pressing problem for healthcare delivery. Turnover contributes to increased recruitment and orientation cost, reduced quality patient care and the loss of mentorship for new nurses. A qualitative, interpretive descriptive approach was used to guide the study. Interviews were conducted with 12 registered nurses, averaging 16 years in practice. Participants were equally represented from an array of acute care inpatient settings. The sample drew on perspectives from point-of-care nurses and nurses in leadership roles, primarily charge nurses and clinical nurse educators. Nurses' decisions to leave practice were influenced by several interrelated work environment and personal factors: higher patient acuity, increased workload demands, ineffective working relationships among nurses and with physicians, gaps in leadership support and negative impacts on nurses' health and well-being. Ineffective working relationships with other nurses and lack of leadership support led nurses to feel dissatisfied and ill equipped to perform their job. The impact of high stress was evident on the health and emotional well-being of nurses. It is vital that healthcare organisations learn to minimise turnover and retain the wealth of experienced nurses in acute care settings to maintain quality patient care and contain costs. This study highlights the need for healthcare leaders to re-examine how they promote collaborative practice, enhance supportive leadership behaviours, and reduce nurses' workplace stressors to retain the skills and knowledge of experienced nurses at the point-of-care. © 2016 John Wiley & Sons Ltd.

How do masculinity, paternity leave, and mortality associate? -A study of fathers in the Swedish parental & child cohort of 1988/89.

PubMed

Månsdotter, Anna; Lundin, Andreas

2010-08-01

One of the proposed causes for the gender gap in longevity is the attitudes and practices culturally prescribed for men, often conceptualised as 'masculinity'. It has also been suggested that paternity leave, indicating a change from breadwinning to caring, could benefit men's lifetime health. In this study, the objective was to examine associations between 'masculinity' (assessed at the age of 18-19 years), paternity leave (1988-1990), and mortality patterns (1991-2008) based on a population of Swedish men who had a child in 1988/89 (N=72,569). 'Masculinity' was measured during the compulsory military conscription process by a psychologist based on leisure and occupational interests, and paternity leave was measured in fulltime days by registry data. The main finding was that low 'masculinity' ranking increased the risk of all-cause mortality, and mortality from alcohol and violent causes, while taking paternity leave between 30 and 135 days decreased the risk of all-cause mortality. However, the weak association found between 'masculinity' and paternity leave indicates that entering a caring role as a father is not predicted by 'masculinity' assessed in late adolescence, and that the studied phenomena influence male mortality independently of each other.

Nakanishi, Miharu; Imai, Hisato

2012-01-01

The aim of the present study is to examine job role quality relating to intention to leave current facility and to leave profession among direct care workers in residential facilities for elderly in Japan. Direct care workers completed a paper questionnaire on October 2009. From 746 facilities in three prefectures (Tokyo, Shizuoka, and Yamagata) 6428 direct care workers with complete data were included in the analyses. The Job Role Quality (JRQ) scale was translated into Japanese language to assess job role quality. Hierarchical multiple regression analysis showed that intention to leave current facility was primarily associated with job role quality: poor skill discretion, high job demand, and poor relationship with supervisor. Intention to leave profession was primarily associated with poor skill discretion. The results of the present study imply the strategies to direct care worker retention for each facility and policy efforts. Each facility can implement specific strategies such as enhanced variety of work and opportunity for use of skills, adequate job allocation, and improvement of supervisor-employee relationship in work place. Policy efforts should enhance broader career opportunities in care working such as advanced specialization and authorized medical practice. Copyright © 2010 Elsevier Ireland Ltd.

Ozone injury and infection of potato leaves by Botrytis cinerea

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

Manning, W.J.; Feder, W.A.; Perkins, I.

1969-09-01

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.

Effect of gibberellic Acid on crown gall tumor induction in aging primary pinto bean leaves.

PubMed

Anand, V K; Bauer, C; Heberlein, G T

1975-06-01

Gibberellic acid was tested for its effect on tumor induction by Agrobacterium tumefaciens in primary pinto bean (Phaseolus vulgaris) leaves in various stages of development. The hormone was found to promote tumor induction in partially aged leaves but did not effect tumor induction in very young leaves or in fully matured leaves. It is suggested that the natural loss of susceptibility to tumor induction in maturing pinto bean leaves is associated with a concomitant loss of endogenous gibberellins and/or a sensitivity to gibberellins.

Ethnoecology of the palm Brahea dulcis (Kunth) Mart. in central Mexico.

Pulido, María T; Coronel-Ortega, Mayte

2015-01-05

There have been few studies on the sustainable use of non-timber forest products in arid and semi-arid zones. The palm Brahea dulcis has been one of the most important resources in semi-arid Mesoamerica, since pre-Hispanic times. Currently, some populations grow within protected natural areas, representing both a challenge and an opportunity for local development. This ethnoecological study of B. dulcis in central Mexico aimed to evaluate their uses, harvesting context, and potential for exploitation, in order to give practical advice on their best use and management. Ethnographic and ecological information was obtained in Barranca de Metztitlán Biosphere Reserve and Valle del Mezquital, Mexico. We studied the population structure and density; additionally, we evaluated the rate of leaf production, leaf renewal rate, percent survival of new leaves, the development of reproductive structures and performed a one-year defoliation experiment (involving a control and four treatments including a mix of semiannual and annual frequency of harvest and removal of two new leaves and/or two mature leaves). Twenty uses of the palm were recorded in the study area. Religious/symbolic and handicraft uses are highlighted. The population density of this species was the highest reported for the genus (1244 ± 231.7 ind/ha). The leaf production rate was the highest reported for arborescent palms of the Americas (11.83 ± 0.036 leaves/individual/year). The sexual reproductive cycle was 2.3 years long. A one-year defoliation experiment did not show statistically significant differences. Recommendations include: 1) implement management focused on increasing the abundance and quality of this useful resource in Metztitlán; 2) employ a strategy of focusing on ethnicity and gender in promoting their exploitation; 3) learn from theoretical frameworks of other non timber forest product studies. We propose that Brahea dulcis is the palm with the highest potential for sustainable use in the arid and semi-arid zones of Mexico. The challenge to improving management includes simplifying the legal protection framework, promoting uses and developing a market strategy. Collaborations to share experiences with peasant farmers from Guerrero is recommended. We further recommend the development of a governmental strategy to enhance and reassess this important resource.

Selective pressures imposed by herbivores are often positively correlated with investments that plants make in defense. Research based on the framework of an evolutionary arms race has improved our understanding of why the amount and types of defenses differ between plant species. However, plant species are exposed to different selective pressures during the life of a leaf, such that expanding leaves suffer more damage from herbivores and pathogens than mature leaves. We hypothesize that this differential selective pressure may result in contrasting quantitative and qualitative defense investment in plants exposed to natural selective pressures in the field. To characterize shifts in chemical defenses, we chose six species of Inga, a speciose Neotropical tree genus. Focal species represent diverse chemical, morphological, and developmental defense traits and were collected from a single site in the Amazonian rainforest. Chemical defenses were measured gravimetrically and by characterizing the metabolome of expanding and mature leaves. Quantitative investment in phenolics plus saponins, the major classes of chemical defenses identified in Inga, was greater for expanding than mature leaves (46% and 24% of dry weight, respectively). This supports the theory that, because expanding leaves are under greater selective pressure from herbivores, they rely more upon chemical defense as an antiherbivore strategy than do mature leaves. Qualitatively, mature and expanding leaves were distinct and mature leaves contained more total and unique metabolites. Intraspecific variation was greater for mature leaves than expanding leaves, suggesting that leaf development is canalized. This study provides a snapshot of chemical defense investment in a speciose genus of tropical trees during the short, few-week period of leaf development. Exploring the metabolome through quantitative and qualitative profiling enables a more comprehensive examination of foliar chemical defense investment.

Once general practitioners have established themselves as principals it may seem there is little else to work for. Lack of stimulation may lead to demoralisation, and it is essential that they have other ways to continue to develop their careers. Meeting other doctors to discuss cases and problems and postgraduate education often help but many doctors want to take on extra roles. The options available include undergraduate teacher, tutor for postgraduate education, and participation in medical audit advisory groups, local medical committees, or royal college faculties. Some general practitioners work part time to allow them to fit in these activities. It may also be possible to obtain extended study leave or a sabbatical to broaden experience. Others even more practice to provide new challenges.

The health and economic benefits of paid parental leave have been well-documented. In 2016, the American College of Obstetricians and Gynecologists released a policy statement about recommended parental leave for trainees; however, data on adoption of said guidelines are nonexistent, and published data on parental leave policies in obstetrics-gynecology are outdated. The objective of our study was to understand existing parental leave policies in obstetrics-gynecology training programs and to evaluate program director opinions on these policies and on parenting in residency. A Web-based survey regarding parental leave policies and coverage practices was sent to all program directors of accredited US obstetrics-gynecology residency programs. Cross-sectional Web-based survey. Sixty-five percent (163/250) of program directors completed the survey. Most program directors (71%) were either not aware of or not familiar with the recommendations of the American College of Obstetricians and Gynecologists 2016 policy statement on parental leave. Nearly all responding programs (98%) had arranged parental leave for ≥1 residents in the past 5 years. Formal leave policies for childbearing and nonchildbearing parents exist at 83% and 55% of programs, respectively. Program directors reported that, on average, programs offer shorter parental leaves than program directors think trainees should receive. Coverage for residents on leave is most often provided by co-residents (98.7%), usually without compensation or schedule rearrangement to reduce work hours at another time (45.4%). Most program directors (82.8%) believed that becoming a parent negatively affected resident performance, and approximately one-half of the program directors believed that having a child in residency decreased well-being (50.9%), although 19.0% believed that it increased resident well-being. Qualitative responses were mixed and highlighted the complex challenges and competing priorities related to parental leave. Most residency programs are not aligned with the American College of Obstetricians and Gynecologists recommendations on paid parental leave in residency. Complex issues regarding conflicting policies, burden to covering co-residents, and impaired training were raised. Copyright © 2018 Elsevier Inc. All rights reserved.

The pre-return-to-work medical consultation during sick leave for low back pain (LBP) aims at assessing the worker's ability to resume working without risk for his/her health, and anticipating any difficulties inherent to returning to work and job retention. This article summarizes the good practices guidelines proposed by the French Society of Occupational Medicine (SFMT) and the French National Health Authority (HAS), and published in October 2013. Good practices guidelines developed by a multidisciplinary and independent task force (24 experts) and peer review committee (50 experts) based on a literature review from 1990 to 2012, according to the HAS methodology. According to the labour regulations, workers can request a medical consultation with their occupational physician at any time. The pre-return-to-work consultation precedes the effective return-to-work and can be requested by the employee regardless of their sick leave duration. It must be scheduled early enough to: (i) deliver reassuring information regarding risks to the lower back and managing LBP; (ii) evaluate prognostic factors of chronicity and prolonged disability in relations to LBP and its physical, social and occupational consequences in order to implement the necessary conditions for returning to work; (iii) support and promote staying at work by taking into account all medical, social and occupational aspects of the situation and ensure proper coordination between the different actors. A better understanding of the pre-return-to-work consultation would improve collaboration and coordination of actions to facilitate resuming work and job retention for patients with LBP.

Olive leaves are known to mature slowly, reaching their maximum photosynthetic activity only after full leaf expansion. Poor assimilation rates, typical to young olive leaves, were previously associated with low stomata conductance. Yet, very little is known about chloroplast biogenesis throughout olive leaf development. Here, the photosynthetic activity and plastids development throughout leaf maturation is characterized by biochemical and ultrastructural analyses. Although demonstrated only low photosynthetic activity, the plastids found in young leaves accumulated both photosynthetic pigments and proteins required for photophosphorylation and carbon fixation. However, Rubisco (ribulose-1,5-bisphosphate carboxylase-oxygenase), which catalyzes the first major step of carbon fixation and one of the most abundant proteins in plants, could not be detected in the young leaves and only slowly accumulated throughout development. In fact, Rubisco levels seemed tightly correlated with the observed photosynthetic activities. Unlike Rubisco, numerous proteins accumulated in the young olive leaves. These included the early light induced proteins, which may be required to reduce the risk of photodamage, because of light absorption by photosynthetic pigments. Also, high levels of ribosomal L11 subunit, transcription factor elF-5A, Histones H2B and H4 were observed in the apical leaves, and in particular a plastidic-like aldolase, which accounted for approximately 30% of the total proteins. These proteins may upregulate in their levels to accommodate the high demand for metabolic energy in the young developing plant tissue, further demonstrating the complex sink-to-source relationship between young and photosynthetically active mature leaves.

Development of the PHAST model: generating standard public health services data and evidence for decision-making.

Standardized data regarding the distribution, quality, reach, and variation in public health services provided at the community level and in wide use across states and communities do not exist. This leaves a major gap in our nation's understanding of the value of prevention activities and, in particular, the contributions of our government public health agencies charged with assuring community health promotion and protection. Public health and community leaders, therefore, are eager for accessible and comparable data regarding preventive services that can inform policy decisions about where to invest resources. We used literature review and a practice-based approach, employing an iterative process to identify factors that facilitate data provision among public health practitioners. This paper describes the model, systematically developed by our research team and with input from practice partners, that guides our process toward maximizing the uptake and integration of these standardized measures into state and local data collection systems. The model we developed, using a dissemination and implementation science framework, is intended to foster greater interest in and accountability for data collection around local health department services and to facilitate spatial exploration and statistical analysis of local health department service distribution, change, and performance. Our model is the first of its kind to thoroughly develop a means to guide research and practice in realizing the National Academy of Medicine's recommendation for developing systems to measure and track state and local public health system contributions to population health.

To explore general practitioners' (GPs') specific negotiation strategies regarding sick-leave issues with patients suffering from subjective health complaints. Focus-group study. Nine focus-group interviews in three cities in different regions of Norway. 48 GPs (31 men, 17 women; age 32-65), participating in a course dealing with diagnostic practice and assessment of sickness certificates related to patients with subjective health complaints. The GPs identified some specific strategies that they claimed to apply when dealing with the question of sick leave for patients with subjective health complaints. The first step would be to build an alliance with the patient by complying with the wish for sick leave, and at the same time searching for information to acquire the patient's perspective. This position would become the basis for the main goal: motivating the patient for a rapid return to work by pointing out the positive effects of staying at work, making legal and moral arguments, and warning against long-term sick leave. Additional solutions might also be applied, such as involving other stakeholders in this process to provide alternatives to sick leave. GPs seem to have a conscious approach to negotiations of sickness certification, as they report applying specific strategies to limit the duration of sick leave due to subjective health complaints. This give-and-take way of handling sick-leave negotiations has been suggested by others to enhance return to work, and should be further encouraged. However, specific effectiveness of this strategy is yet to be proven, and further investigation into the actual dealings between doctor and patients in these complex encounters is needed.

The nursing shortage is a critical issue in many countries. High turnover rates among nurses is contributing to the shortage, and job dissatisfaction, intention to leave, and burnout have been identified as some of the predictors of nurse turnover. A well-established body of evidence demonstrates that the work environment for nurses influences nurse job dissatisfaction, intention to leave, and burnout, but there never has been a study undertaken in Thailand to investigate this relationship. To investigate how work environment affects job dissatisfaction, burnout, and intention to leave among nurses in Thailand. The study used a cross-sectional survey to collect data from 1351 nurses working in 43 inpatient units in five university hospitals across Thailand. The participants completed the Practice Environment Scale of the Nursing Work Index, the Maslach Burnout Inventory, and measures of job dissatisfaction and intention to leave. Logistical regression models assessed the association between work environment and nurse-reported job dissatisfaction, burnout, and intent to leave. Nurses working in university hospitals with better work environments had significantly less job dissatisfaction, intention to leave, and burnout. The nurse work environment is a significant feature contributing to nurse retention in Thai university hospitals. Improving the work environment for nurses may lead to lower levels of job dissatisfaction, intention to leave, and burnout. Focusing on these nurse outcomes can be used as a strategy to retain nurses in the healthcare system. Addressing the challenges of poor work environments requires coordinated action from policymakers and health managers. © 2016 International Council of Nurses.

Medical leave granted to psychiatric inpatients--a one-year retrospective review.

Koh, K G; Ang, A W

2000-09-01

Of the 676 patients warded in 1998 at the National University Hospital (NUH) Department of Psychological Medicine, over a third (n = 268) required certification of absence from work. Duration of inpatient stay and immediate post-discharge medical leave were examined for this group. These durations were correlated against the patients' diagnoses and their demographic variables. The mental health morbidity of teachers was specifically studied. In this retrospective study, we used medical certificate counterfoils to determine the lengths of admission and post-discharge medical leave duration. ANOVA and Kruskal-Wallis tests of the SPSS computer package were used for statistical analysis. The sex and marital status of these patients did not affect either duration significantly. However, those 45 years and older were granted longer outpatient medical leave. Patients diagnosed with mood and psychotic disorders required longer inpatient stay and were granted longer outpatient medical leave, as compared with other diagnostic groups. It was found that the teachers admitted were largely 45 years and older, had a diagnosis of depression and required extended periods of outpatient medical leave compared to other occupational groups. The mean number of days of inpatient stay and outpatient medical leave may serve as a helpful guideline of current practice. As introduced in this paper, the use of medical certificate counterfoils is a simple yet effective way of measuring days off-work. With the inclusion of those psychiatric patients not working and the medical leave granted long after discharge, calculations of the economic costs of specific mental disorders to Singapore can then be attempted.

An Analysis of Paid Family and Sick Leave Advocacy in Louisiana: Lessons Learned.

Raabe, Phyllis Hutton; Theall, Katherine P

In contrast with other developed countries, the United States lacks national paid maternity/family and sick leave policies, negatively impacting the health and economic security of both female and male workers and their children. Employer paid family and sick leave policies cover only about half of workers, and those lacking paid leaves are more likely to be less educated and with lower incomes. Louisiana has high proportions of poor and low income workers who especially would benefit from national or state paid leave policies. In the absence of national paid leaves, several states and cities have implemented paid family and sick leaves. In this context and following the American Public Health Association's endorsement of paid family and sick leaves for health and wellbeing, the Tulane University Mary Amelia Women's Center decided to advocate for paid leave policies in Louisiana. Highlights of a Louisiana spring 2015 initiative were a talk by the President of the Institute for Women's Policy Research on the economic and health benefits of paid family and sick leaves and bills submitted by a State Senator. As has happened elsewhere, opposition from businesses and Republican legislators blocked passage. This outcome fit the Center's original expectations that communicating about the important health and other benefits of paid family and sick leaves, and developing support for state-wide policies, would be a long process-but one important to begin. The initiative in Louisiana may provide insights for paid leave advocacy elsewhere. Copyright © 2016 Jacobs Institute of Women's Health. Published by Elsevier Inc. All rights reserved.

Seeking greener pastures? The relationship between career satisfaction and the intention to emigrate: a survey of Ghanaian physicians.

A significant number of physicians from developing nations emigrate to developed nations in search of better career opportunities. In addition to crippling the health systems of developing nations, the emigration of physicians from sub-Saharan African (SSA) countries results in a loss of return on investment to these nations. The purpose of this study was to identify the relationship between career satisfaction and the intention of active Ghanaian physicians to leave the country within the next 5 years. This study was a cross-sectional correlational study using data from a survey of practicing physicians in Ghana. The primary independent variables examined were dimensions of career satisfaction, assessed using an abridged form of the Physician Work Life Survey. Data from the multivariate ordered logistic regression model indicated that physicians who were house officers or medical officers and those who reported dissatisfaction with their compensation were more likely to report that they were thinking about leaving Ghana within the next 5 years. Health policies aimed at increasing monetary compensation and providing junior physicians with the resources needed to excel in their careers may improve the retention of physicians in Ghana. © The Author 2014.

Concentrations of the elements Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn were measured in the leaves and bark of Robinia pseudoacacia and the soil in which it grew, in the town of Oleśnica (SW Poland) and at a control site. We selected this town because emission from motor vehicles is practically the only source of air pollution, and it seemed interesting to evaluate its influence on soil and plants. The self-organizing feature map (SOFM) yielded distinct groups of soils and R. pseudoacacia leaves and bark, depending on traffic intensity. Only the map classifying bark samples identified an additional group of highly polluted sites along the main highway from Wrocław to Warszawa. The bark of R. pseudoacacia seems to be a better bioindicator of long-term cumulative traffic pollution in the investigated area, while leaves are good indicators of short-term seasonal accumulation trends.

Musculoskeletal disorders among preschool teachers: analyzing the relationships among relational demands, work meaning, and intention to leave the job.

Based on the conservation of resource (COR) theory by Hobfoll, the aim of the present study was to test whether the relationships among relational demands, work meaning, and intention to leave vary as a function of the presence of musculoskeletal disorders (MSDs). The study was cross-sectional and non-randomized. Analyses were carried out on a dataset consisting of 429 preschool teachers, who filled out a self-report questionnaire. Of them, 238 reported a MSD diagnosis and 191 were free form MSDs. As expected, among those who reported MSDs, relational demands were significantly associated to intention to leave, and this relationship was mediated by work meaning; moreover, among those free from MSDs, no significant paths among the three variables were found. In general, results showed that suffering from MSDs impairs workers' ability to face to relational demands, thus activating a spiral that encompasses diminished work meaning and intention to leave. Practical implications of results will be discussed in the paper.

Background Despite the provision of maternity leave offered to mothers, many American women fail to take leave. Methods We developed an evidence-based maternity leave educational tool for working women in California using participatory design. We tested its short-term efficacy with a randomized controlled trial of pregnant English-speakers (n=155). Results Among intervention participants exposed to the tool, 65% reported that they learned something new; 38% were motivated to seek more information; and 49% said it helped them plan their maternity leave. Among participants who delivered at ≥ 37 weeks gestation and said the tool helped them plan their leave, 89% took more than one week of prenatal leave, a significantly higher proportion than among controls who did not receive the tool (64%, p=0.049). Other findings favored trial participants, but were not statistically significant in this small sample. More intervention participants took some prenatal leave (80%) vs. controls (74%, p=0.44). Among participants who had returned to work when surveyed (n=50), mean postnatal leave uptake was on average 1 week longer for intervention participants vs. controls (13.3 vs. 12.2 weeks, p=0.54). Conclusions The first-phase evaluation of this tool shows that it successfully informed women about maternity leave options, clarified complex regulations, encouraged women to seek further information and helped plan maternity leave. Compared to controls, trial participants who used the tool to plan their leave were far more likely to take prenatal leave close to term. Future evaluation of the tool when mediated by a health provider or employer is warranted. PMID:26107519

Heavy recreational visitation within protected natural areas has resulted in many ecological impacts. Many of these impacts may be avoided or minimized through adoption of low-impact hiking and camping practices. Although ?No Trace? messages have been promoted in public lands since the 1970s, few studies have documented the reception and effectiveness of these messages. The U.S. Leave No Trace Center for Outdoor Ethics develops and promotes two-day Trainer courses that teach Leave No Trace (LNT) skills and ethics to outdoor professionals, groups, and interested individuals. This study examined the change in knowledge, ethics, and behavior of LNT Trainer course participants. The respondents were a convenience sample of participants in Trainer courses offered from April through August 2003. Trainer course instructors administered pre-course and post-course questionnaires to their participants, and we contacted participants individually with a followup questionnaire 4 months after completion of their course. Scores for each of the sections increased immediately following the course, and decreased slightly over the 4 months following the course. Overall, more than half of the knowledge and behavior items, and half of the ethics items, showed significant improvement from pre-course measures to the follow-up. Age, reported LNT experience, and backpacking experience affected the participants? pre-course knowledge and behavior scores. Younger, less experienced respondents also showed a greater improvement in behavior following the course. Trainer course participants also shared their LNT skills and ethics with others both formally and informally. In summary, the LNT Trainer course was successful in increasing participants? knowledge, ethics, and behavior, which they then shared with others. Since many low impact skills taught in the LNT curriculum are supported by scientific research, LNT educational programs have the potential to effectively minimize the environmental impacts caused by outdoor recreationists. Research implications for improving LNT training and instruction are described.

Previous works show the development of thicker leaves on tolerant plants growing under cadmium (Cd 2+ ) contamination. The aim of this study was to evaluate the Cd 2+ effects on the leaf meristems of the tolerant species Schinus molle. Plants were grown in nutrient solution containing 0, 10, and 50 μM of Cd 2+ . Anatomical analysis was performed on leaf primordia sampled at regular time intervals. Under the lowest Cd 2+ level (10 μM), increased ground meristem thickness, diameter of the cells, cell elongation rate, and leaf dry mass were found. However, 50 μM of Cd 2+ reduced all these variables. In addition, the ground meristem cells became larger when exposed to any Cd 2+ level. The epidermis, palisade parenchyma, and vascular tissues developed earlier in Cd 2+ -exposed leaves. The modifications found on the ground meristem may be related to the development of thicker leaves on S. molle plants exposed to low Cd 2+ levels. Furthermore, older leaves showed higher Cd 2+ content when compared to the younger ones, preventing the Cd 2+ toxicity to these leaves. Thus, low Cd 2+ concentrations change the ground meristem structure and function reflecting on the development of thicker and enhanced leaves.

An alternative simple method for preparing and preserving cross-section of leaves and roots in herbaceous plants: Case study in Orchidaceae

This alternative method provides a simple and faster procedure for preparing cross-sections of leaves and roots in herbaceous plants, especially for living specimens of orchids (Orchidaceae). This method used a clamp-on hand sliding microtome to make cross-sections of leaves and roots, with sections preserved inside the microtubes containing preservation liquid. This preservation technique allowed the sections to be restained and to be used for further usage in future. This method was more practical than the paraffin embedding method because it does not need the additional steps of paraffin embedding and deparaffinization. It may also provide better cross-section results than free-hand sectioning method. The procedure is very feasible and is recommended for use in plant anatomy observation.

Different structural and functional changes take place during leaf development. Since some of them are highly connected to oxidative metabolism, regulation of reactive oxygen species (ROS) abundance is required. Most of the reactive oxygen species ROS in plant cells are produced in chloroplasts as a result of highly energetic reactions of photosynthesis. The aim of our study was to examine the changes in concentration of oxidative stress parameters (TBARS - thiobarbituric acid-reacting substances and protein carbonyls) as well as antioxidative strategies during development of maple (Acer platanoides L.) leaves in the light of their enhanced photosynthetic performance. We reveal that biogenesis of the photosynthetic apparatus during maple leaf maturation corresponded with oxidative damage of lipids, but not proteins. In addition, antioxidative responses in young leaves differed from that in older leaves. Young leaves had high values of non-photochemical quenching (NPQ) and catalase (CAT, EC 1.11.1.6) activity which declined during the maturation process. Developing leaves were characterized by an increase in TBARS level, the content of non-enzymatic antioxidants as well as ascorbate peroxidase activity (APX, EC 1.11.1.11), while the content of protein carbonyls decreased with leaf maturation. Fully developed leaves had the highest lipid peroxidation level accompanied by a maximum in ascorbic acid content and superoxide dismutase activity (SOD, EC1.15.1.1). These observations imply completely different antioxidative strategies during leaf maturation enabling them to perform their basic function. Copyright © 2011 Elsevier Masson SAS.

The application of amino acids in crops has been a common practice in recent years, although most of the time they are associated with products based on algae extracts or on fermented animal or vegetable wastes. However, little is known about the isolated effect of amino acids on the development of crops. Therefore, the objective of this research was to evaluate the effect of the application of isolated amino acids on the in some steps of the soybean nitrogen metabolism and on productivity. Experiments were carried out in a greenhouse and in the field with the application of the amino acids glutamate (Glu), phenylalanine (Phe), cysteine (Cys) and glycine (Gly) and as a set (Glu+Phe+Cys+Gly), as seed treatment (ST), as foliar application (FA) and both (ST+FA), at the V 4 growth stage. Evaluations consisted of nitrate reductase and urease activities, nitrate, ureide, total amino acids and total nitrogen content in leaves, and productivity. The application of Glu to leaves, Cys as ST and a mixture of Glu+Cys+Phe+Gly as ST+FA in the greenhouse experiment increased the total amino acids content. In the field experiment all treatments increased the amino acid content in leaves. At the V 6 stage in the field experiment, all modes of Gly application, Glu as ST and FA, Cys and Phe as ST+FA and Glu+Cys+Phe+Gly as FA increased the nitrate content in leaves. In the greenhouse, application of Cys and Phe as ST increased the production of soybean plants by at least 21%. The isolated application of Cys, Phe, Gly, Glu and the set of these amino acids as ST increased the productivity of soybean plants in the field experiment by at least 22%.

Firm behavior, environmental externalities and public policy

NASA Astrophysics Data System (ADS)

Curtis, Earnest Markell, IV

This dissertation consists of three essays which examine environmental policy, employer mandates and energy consumption. The essays explore how firms respond to government policies such as environmental regulation and employer mandates. Understanding how firms adjust to government policies is crucial to law makers attempting to design optimal policies that maximize net benefits to society. The first essay, titled Who Loses under Power Plant Cap-and-Trade Programs tests how a major cap-and-trade program, known as the NOx Budget Trading Program (NBP), affected labor markets in the region where it was implemented. The cap-and-trade program dramatically decreased levels of NOx emissions and added substantial costs to energy producers. Using a triple-differences approach that takes advantage of the geographic and time variation of the program as well as variation in industry energy-intensity levels, I examine how employment dynamics changed in manufacturing industries whose production process requires high levels of energy. After accounting for a variety of flexible state, county and industry trends, I find that employment in the manufacturing sector dropped by 1.7% as a result of the NBP. Young workers experienced the largest employment declines and earnings of newly hired workers fell after the regulation began. Employment declines are shown to have occurred primarily through decreased hiring rates rather than increased separation rates, thus mitigating the impact on incumbent workers. The second essay, titled Evaluating Workplace Mandates with Flows versus Stocks: An Application to California Paid Family Leave uses an underexploited data set to examine the impact of the California Paid Family Leave program on employment outcomes for young women. Most papers on mandated benefits examine labor outcomes by looking at earnings and employment levels of all workers. Examining these levels will be imprecise if the impacts of the program develop over time and firms are wary to immediately adjust employment and wages for existing workers. Using Quarterly Workforce Indicator data, we are able to measure the impact on hires, new hire earnings, separations and extended leaves among young women. Earnings for young female new hires fell in California relative to other workers, but changed little relative to country-wide comparison groups. We find strong evidence that separations (of at least three months) among young women and the number and shares of young female new hires increased. Many young women that separate (leave the payroll) eventually return to the same firm. Increased separation and hiring rates among young women in the labor market ("churning") may reflect both increased time spent with children and greater job mobility (i.e., reduced job lock) as the result of mandated paid family leave across the labor market. The third essay, Evidence of an Energy Management Gap in U.S. Manufacturing: Spillovers from Firm Management Practices to Energy Efficiency, merge a well-cited survey of firm management practices into confidential plant level U.S. Census manufacturing data to examine whether generic, i.e. non-energy specific, firm management practices, "spillover" to enhance energy efficiency in the United States. For U.S. manufacturing plants we find this relationship to be more nuanced than prior research on UK plants. Most management techniques are shown to have beneficial spillovers to energy efficiency, but an emphasis on generic targets, conditional on other management practices, results in spillovers that increase energy intensity. Our specification controls for industry specific effects at a detailed 6-digit NAICS level and finds the relationship between management and energy use to be strongest for firms in energy intensive industries. We interpret the empirical result that generic management practices do not necessarily spillover to improved energy performance as evidence of an "energy management gap."

To study the relationship between HPLC fingerprint chromatogram and inhibitory effect on respiratory burst of rat PMN of leaves of crataegus L. HPLC fingerprint peaks of different species of hawthorn leaves were isolated and used for the effective experiment on the respiratory burst of rat PMN. The mathematic models of the relationship between the area and the effect of fingerprint peaks were established. According to the mathematic models, the HPLC fingerprint were change into bioactive fingerprint (include effective fingerprint and potency fingerprint) with the helps of mathematics, chemometrics, computer program simulation and etc. The chromatogram-effect relationship of leaves of crataegus. on respiratory burst of rat PMN was established. According to this relationship, the activities of fourteen samples of leaves of crataegus. were forecasted. It was positive correlation between the expected value and the practical value. And the correlation coefficients was 0.968 (P < 0.01). An all-around evaluative system, which includes not only chemical identification but also effective evaluation for traditional Chinese medicine was established. It will provide a new idea for study on fingerprint chromatogram of traditional Chinese medicine.

Exploring Patients' Views Toward Giving Web-Based Feedback and Ratings to General Practitioners in England: A Qualitative Descriptive Study.

Patient feedback websites or doctor rating websites are increasingly being used by patients to give feedback about their health care experiences. There is little known about why patients in England may give Web-based feedback and what may motivate or dissuade them from giving Web-based feedback. The aim of this study was to explore patients' views toward giving Web-based feedback and ratings to general practitioners (GPs), within the context of other feedback methods available in primary care in England, and in particular, paper-based feedback cards. A descriptive exploratory qualitative approach using face-to-face semistructured interviews was used in this study. Purposive sampling was used to recruit 18 participants from different age groups in London and Coventry. Interviews were transcribed verbatim and analyzed using applied thematic analysis. Half of the participants in this study were not aware of the opportunity to leave feedback for GPs, and there was limited awareness about the methods available to leave feedback for a GP. The majority of participants were not convinced that formal patient feedback was needed by GPs or would be used by GPs for improvement, regardless of whether they gave it via a website or on paper. Some participants said or suggested that they may leave feedback on a website rather than on a paper-based feedback card for several reasons: because of the ability and ease of giving it remotely; because it would be shared with the public; and because it would be taken more seriously by GPs. Others, however, suggested that they would not use a website to leave feedback for the opposite reasons: because of accessibility issues; privacy and security concerns; and because they felt feedback left on a website may be ignored. Patient feedback and rating websites as they currently are will not replace other mechanisms for patients in England to leave feedback for a GP. Rather, they may motivate a small number of patients who have more altruistic motives or wish to place collective pressure on a GP to give Web-based feedback. If the National Health Service or GP practices want more patients to leave Web-based feedback, we suggest they first make patients aware that they can leave anonymous feedback securely on a website for a GP. They can then convince them that their feedback is needed and wanted by GPs for improvement, and that the reviews they leave on the website will be of benefit to other patients to decide which GP to see or which GP practice to join.

Crystal macropattern development in Prunus serotina (Rosaceae, Prunoideae) leaves.

2006-05-01

Prunus, subgenus Padus, exhibits two completely different calcium oxalate crystal macropatterns in mature leaves. Foliar macropattern development has been described previously in P. virginiana, representing one version. Prunus serotina, in the group exhibiting the second macropattern, is described here. The goal was to describe developmental details for comparison with P. virginiana, and to extend the sparse current knowledge of crystal macropatterns. Leaves at various developmental stages were removed from local trees and from herbarium specimens. Early leaf stages and freehand leaf and stem sections were mounted directly in aqueous glycerine; larger leaves were processed whole or in representative pieces in household bleach, dehydrated in alcohol/xylol, and mounted in Permount. Crystals were detected microscopically between crossed polarizers. Bud scales have a dense druse population. Druses appear first at the stipule tip and proliferate basipetally but soon stop forming; growing stipules therefore have a declining density of druses. Druses appear at the tip of leaves <1 mm long, then proliferate basipetally in the midrib. Lamina druses appear in the distal marginal teeth of leaves 3 cm long; from here they proliferate basipetally and towards midrib along major veins. In about two-thirds-grown leaves (6-9 cm length) druses are all adaxial to veins of most orders; a shift occurs then to formation of prisms, which appear first abaxial to, then all around, veins. Mature leaves have virtually all prisms encrusting all major veins, more sparsely along smaller minor veins. Late season leaves form epitactic crystals on existing prismatics. The developing and mature macropattern of P. serotina is almost the reverse of the pattern described previously in P. virginiana, and shows that two closely related species can develop radically different modes of crystallization. The few detailed macropattern studies to date reveal striking variations that indicate a new level of organization that must be integrated with the anatomical, physiological and molecular approaches that have been dominant so far.

Working women of childbearing age are a vital part of the population. Following childbirth, this group of women can experience a myriad of physical and mental health problems that can interfere with their ability to work. Currently, there is little known about cost-effective post-partum interventions to prevent work disability. The purpose of the study was to evaluate whether supervisor telephone contact (STC) during maternity leave is cost-effective from a societal perspective in reducing sick leave and improving quality-adjusted life years (QALYs) compared to common practice (CP). We conducted an economic evaluation alongside a randomized controlled trial. QALYs were measured by the EuroQol 5-D, and sick leave and presenteeism by the Health and work Performance Questionnaire. Resource use was collected by questionnaires. Data were analysed according to intention-to-treat. Missing data were imputed via multiple imputation. Uncertainty was estimated by 95% confidence intervals, cost-utility planes and curves, and sensitivity analyses. 541 working women from 15 companies participated. Response rates were above 85% at each measurement moment. At the end of the follow-up, no statistically significant between-group differences in QALYs, mean hours of sick leave or presenteeism or costs were observed. STC was found to be less effective and more costly. For willingness-to-pay levels from €0 through €50,000, the probability that STC was cost-effective compared to CP was 0.2. Overall resource use was low. Mean total costs were €3678 (95% CI: 3386; 3951). Productivity loss costs represented 37% of the total costs and of these costs, 48% was attributable to sick leave and 52% to work presenteeism. The cost analysis from a company's perspective indicated that there was a net cost associated with the STC intervention. STC was not cost-effective compared to common practice for a healthy population of working mothers; therefore, implementation is not indicated. The cost-utility of STC for working mothers with more severe post-partum health problems, however, needs to be investigated. Work presenteeism accounted for half of the total productivity loss and warrants attention in future studies. ISRCTN: ISRCTN73119486.

Brazilian off-season maize production is characterized by low yield due to several factors, such as climate variability and inadequate management practices, specifically weed management. Thus, the goal of this study was to determinate the critical period of weed competition in off-season maize (Zea mays L.) crop using thermal units or growing degree days (GDD) approach to characterize crop growth and development. The study was carried out in experimental area of the University of São Paulo, Brazil, with weed control (C), as well as seven coexistence periods, 2, 4, 6, 8, and 12 leaves, flowering, and all crop cycle; fourteen treatments were done. Climate data were obtained from a weather station located close to the experimental area. To determine the critical period for weed control (CPWC) logistic models were fitted to yield data obtained in both W and C, as a function of GDD. For an arbitrary maximum yield loss fixed in 2.5%, the CPWC was found between 301 and 484 GDD (7-8 leaves). Also, when the arbitrary loss yield was fixed in 5 and 10%, the period before interference (PBI) was higher than the critical weed-free period (CWFP), suggesting that the weeds control can be done with only one application, between 144 and 410 GDD and 131 and 444 GDD (3-8 leaves), respectively. The GDD approach to characterize crop growth and development was successfully used to determine the critical period of weeds control in maize sown off-season. Further works will be necessary to better characterize the interaction and complexity of maize sown off-season with weeds. However, these results are encouraging because the possibility of the results to be extrapolated and because the potential of the method on providing important results to researchers, specifically crop modelers.

Chemical Utilization of Albizia lebbeck Leaves for Developing Protein Concentrates as a Dietary Supplement.

2017-08-17

In search of nonconventional sources of protein to combat widespread malnutrition, the possibility of developing a protein concentrate as an alternative dietary supplement from abundantly available yet poorly valorized leaves of Albizia lebbeck (siris) was examined. A process for recovery of leaf protein concentrate (LPC) from these leaves was optimized and applied for isolation of LPCs from lower, middle, and upper canopies of the tree. The optimized conditions (leaves to water 1:9, coagulation at pH 4.0 using 1 N citric acid at 90°C for 11 minutes) afforded LPCs containing protein 37.15%, 37.57%, and 37.76% in 5.99%, 5.97%, and 6.07% yield, respectively. The proximate nutritional composition, pigments, minerals, in vitro digestibility, and antinutritional factors of these LPCs were determined. Analysis of variance of these data revealed no significant difference with respect to canopy. Use of Albizia lebbeck leaves for development of LPC as a food/feed supplement was revealed.

Estimates of leaf area index from spectral reflectance of wheat under different cultural practices and solar angle

Asrar, G.; Kanemasu, E. T.; Yoshida, M.

1985-01-01

The influence of management practices and solar illumination angle on the leaf area index (LAI) was estimated from measurements of wheat canopy reflectance evaluated by two methods, a regression formula and an indirect technique. The date of planting and the time of irrigation in relation to the stage of plant growth were found to have significant effects on the development of leaves in spring wheat. A reduction in soil moisture adversely affected both the duration and magnitude of the maximum LAI for late planting dates. In general, water stress during vegetative stages resulted in a reduction in maximum LAI, while water stress during the reproductive period shortened the duration of green LAI in spring wheat. Canopy geometry and solar angle also affected the spectral properties of the canopies, and hence the estimated LAI. Increase in solar zenith angles resulted in a general increase in estimated LAI obtained from both methods.

Recent research has helped to cultivate growing awareness that machine-learning systems fueled by big data can create or exacerbate troubling disparities in society. Much of this research comes from outside of the practicing data science community, leaving its members with little concrete guidance to proactively address these concerns. This article introduces issues of discrimination to the data science community on its own terms. In it, we tour the familiar data-mining process while providing a taxonomy of common practices that have the potential to produce unintended discrimination. We also survey how discrimination is commonly measured, and suggest how familiar development processes can be augmented to mitigate systems' discriminatory potential. We advocate that data scientists should be intentional about modeling and reducing discriminatory outcomes. Without doing so, their efforts will result in perpetuating any systemic discrimination that may exist, but under a misleading veil of data-driven objectivity.

Background It is commonly assumed that oncology nurses experience high job-related burnout and high turnover because their work involves inherent stressors such as caring for patients with serious and often life-threatening illness. Objectives The objectives of this study were to examine the differences in outcomes such as job dissatisfaction and burnout between oncology nurses and medical-surgical nurses, and to identify factors that affect oncology nurse outcomes. Methods A secondary analysis of nurse survey data collected in 2006 including 4047 nurses from 282 hospitals in 3 states was performed; t test and χ2 test compared differences between oncology nurses and medical-surgical nurses in nurse outcomes and their assessments of nurse practice environment, as measured by the Practice Environment Scale of the Nursing Work Index. Logistic regression models estimated the effect of nurse practice environment on 4 nurse-reported outcomes: burnout, job dissatisfaction, intention to leave the current position, and perceived quality of care. Results Oncology nurses reported favorable practice environments and better outcomes than did medical-surgical nurses. All 4 subscales of the Practice Environment Scale of the Nursing Work Index studied were significantly associated with outcomes. Specifically, nurses who reported favorable nursing foundations for quality of care (eg, active in-service or preceptorship programs) were less likely to report burnout and leave their current position. Conclusions Better practice environments, including nurse foundations for quality care, can help to achieve optimal nurse outcomes. Implications for Practice Improving hospital practice environments holds significant potential to improve nurse well-being, retention, and quality of care. Specifically, hospitals should consider preceptor programs and continuing education and increase nurses’ participation in hospital decision making. PMID:22751101

Ranunculus trichophyllus is an amphibious plant that produces thin and cylindrical leaves if grown under water but thick and broad leaves if grown on land. We found that such heterophylly is widely controlled by two plant hormones, abscisic acid (ABA) and ethylene, which control terrestrial and aquatic leaf development respectively. Aquatic leaves produced higher levels of ethylene but lower levels of ABA than terrestrial leaves. In aquatic leaves, their distinct traits with narrow shape, lack of stomata, and reduced vessel development were caused by EIN3-mediated overactivation of abaxial genes, RtKANADIs, and accompanying with reductions of STOMAGEN and VASCULAR-RELATED NAC-DOMAIN7 (VDN7). In contrast, in terrestrial leaves, ABI3-mediated activation of the adaxial genes, RtHD-ZIPIIIs, and STOMAGEN and VDN7 established leaf polarity, and stomata and vessel developments. Heterophylly of R.trichophyllus could be also induced by external cues such as cold and hypoxia, which is accompanied with the changes in the expression of leaf polarity genes similar to aquatic response. A closely-related land plant R. sceleratus did not show such heterophyllic responses, suggesting that the changes in the ABA/ethylene signaling and leaf polarity are one of key evolutionary steps for aquatic adaptation.

The project aimed to improve the effectiveness of nutritional screening and assessment practices through clinical audits and the implementation of evidence-based practice recommendations. In the absence of optimal nutrition, health may decline and potentially manifest as adverse health outcomes. In a hospitalized person, poor nutrition may adversely impact on the person's outcome. If the nutritional status can be ascertained, nutritional needs can be addressed and potential risks minimized.The overall purpose of this project was to review and monitor staff compliance with nutritional screening and assessment best practice recommendations ensuring there is timely, relevant and structured nutritional therapeutic practices that support safe, compassionate and person-centered care in adults in a tertiary hospital in South Western Sydney, Australia, in the acute care setting. A baseline retrospective chart audit was conducted and measured against 10 best practice criteria in relation to nutritional screening and assessment practices. This was followed by a facilitated multidisciplinary focus group to identify targeted strategies, implementation of targeted strategies, and a post strategy implementation chart audit.The project utilized the Joanna Briggs Institute Practical Application of Clinical Evidence System (JBI PACES) and Getting Research into Practice (GRIP) tool, including evidence from other available supporting literature, for promoting change in healthcare practice. The baseline audit revealed deficits between current practice and best practice across the 10 criteria. Barriers for implementation of nutritional screening and assessment best practice criteria were identified by the focus group and an education strategy was implemented. There were improved outcomes across all best practice criteria in the follow-up audit. The baseline audit revealed gaps between current practice and best practice. Through the implementation of a targeted education program and resource package, outcomes improved in the follow up audit. The findings indicated that engagement from multidisciplinary team members and consumers was effective in developing tailored education that improved knowledge of best practice. This was demonstrated by an increase in the percentage of compliance across the 10 criteria, although leaving room for more improvement. A policy has been developed for implementation and future audits are planned to measure whether improved practices have been sustained.

Plant resistance inducers, also called elicitors, could be useful to reduce the use of pesticides. However, their performance in controlling diseases in the field remains unsatisfactory due to lack of specific knowledge of how they can integrate crop protection practices. In this work, we focused on apple crop and acibenzolar- S -methyl (ASM), a well-known SAR (systemic acquired resistance) inducer of numerous plant species. We provide a protocol for orchard-effective control of apple scab due to the ascomycete fungus Venturia inaequalis , by applying ASM in combination with a light integrated pest management program. Besides we pave the way for future optimization levers by demonstrating in controlled conditions (i) the high influence of apple genotypes, (ii) the ability of ASM to prime defenses in newly formed leaves, (iii) the positive effect of repeated elicitor applications, (iv) the additive effect of a thinning fruit agent.

The Financial Accounting Foundation's (FAF's) November 1989 decision to uphold the 1984 jurisdictional arrangement between the Financial Accounting Standards Board (FASB) and the Government Accounting Standards Board (GASB) leaves little doubt that the healthcare industry will now be subject to two sets of accounting standards. The FAF's decision created a distinction between the accounting practices of government-owned hospitals and non-hospital governmental entities and their adherence to standards set by FASB, GASB, and the American Institute of Certified Public Accountants. A governmental healthcare organization should carefully determine which accounting rules it follows and remain attentive to further GASB developments.

PURPOSE We undertook a study to evaluate the effects of medical home transformation on job satisfaction in the primary care setting. METHODS We collected primary data from 20 primary care practices participating in medical home pilot projects in Rhode Island and Colorado from 2009 to 2011. We surveyed clinicians and staff about the quality of their practice environments (eg, office chaos, communication, difficulties in providing safe, high-quality care) and job satisfaction at baseline and 30 months, and about stress, burnout, and intention to leave at 30 months. We interviewed practice leaders about the impact of pilot project participation. We assessed longitudinal changes in the practice environment and job satisfaction and, in the final pilot year, examined cross-sectional associations between the practice environment and job satisfaction, stress, burnout, and intention to leave. RESULTS Between baseline and 30 months, job satisfaction improved in Rhode Island (P =.03) but not in Colorado. For both pilot projects, reported difficulties in providing safe, high-quality care decreased (P <.001), but emphasis on quality and the level of office chaos did not change significantly. In cross-sectional analyses, fewer difficulties in providing safe, high-quality care and more open communication were associated with greater job satisfaction. Greater office chaos and an emphasis on electronic information were associated with greater stress and burnout. CONCLUSIONS Medical home transformations that emphasize quality and open communication while minimizing office chaos may offer the best chances of improving job satisfaction. PMID:25024241

To select rabbiteye blueberry leaves from an appropriate harvest season to develop functional foods, this paper studied the bioactive secondary metabolites and the antioxidant capacity of rabbiteye blueberry leaves from May, September, and November. The results showed the leaves from May had the highest content of total flavonoids (114.21 mg/g) and the leaves from November had the highest content of total polyphenols and proanthocyanidins (425.24 and 243.29 mg/g, respectively). It was further found that blueberry leaves from different seasons have similar bioactive constituents, but their contents are obviously different by HPLC. The rabbiteye blueberry leaves from November had the highest antioxidant capacity, which was well correlated with their highest proanthocyanidin content. The results clarify that the blueberry leaves from different seasons have different contents of bioactive secondary metabolites and different antioxidant activities, which implied that leaves from November should be selected first for utilization in functional foods.

Human resource (HR) practices, such as training and communication, have been linked to positive employee job commitment and lower turnover intent for direct care workers (DCWs). Not many studies have looked at the combined interaction of HR practices and organizational structure. The aim of this study is to examine the relationship between organizational structure (centralization, formalization, and span of control) and HR practices (training, horizontal communication, and vertical communication) on DCW's job satisfaction and turnover intent. Data were collected from 58 long-term care facilities in five states. We used latent class analysis to group facility characteristics into three sets of combinations: "organic," "mechanistic," and "minimalist." We used multivariate regression to test the relationship of each of these groups on DCW's job satisfaction and turnover intent. After controlling for state, organizational, and individual covariates, the organic group, which represents decentralized and less formalized structures and high levels of job training and communication, was positively related to job satisfaction and negatively related to intent to leave. On the other hand, the minimalist group, which is characterized by low levels of job-related training and communication, showed no significant differences from the mechanistic group (referent) on job satisfaction and intent to leave. These findings imply that managers in long-term care facilities may want to consider adopting organic, decentralized structures and HR practices to retain DCWs.

Implementing a Paid Leave Policy for Graduate Students at UW-Madison: The Department Chair Perspective

NASA Astrophysics Data System (ADS)

Mathieu, Robert D.

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.

Protection of groundnut plants from rust disease by application of glucan isolated from a biocontrol agent Acremonium obclavatum.

Prior treatment of groundnut leaves with glucan isolated from a biocontrol agent, Acremonium obclavatum, protected against the rust disease. Glucan treated leaves showed increased levels of chitinase and β-1,3-glucanase in the apoplastic fluid. An increase in endogenous levels of salicylic acid also was observed in treated leaves. Treated leaves also showed a significant reduction in rust disease development in groundnut leaves. Enhanced activities of glucanohydrolases of treated groundnut leaves might have affected the biotrophic rust pathogen, which is known to colonize in the apoplastic spaces.

Biomonitoring of PAHs by using Quercus ilex leaves: Source diagnostic and toxicity assessment

NASA Astrophysics Data System (ADS)

De Nicola, Flavia; Claudia, Lancellotti; MariaVittoria, Prati; Giulia, Maisto; Anna, Alfani

2011-03-01

Quercus ilex L. leaves were sampled at nineteen urban sites and two remote sites in order to evaluate PAH contamination degree. One-, two- and three-year-old leaves were collected and leaf lipid content was measured to investigate the influence of leaf age and lipids in PAH accumulation. Some PAH diagnostic ratios, such as Ant/Ant + Phen, Flt/Flt + Pyr, B[a]A/B[a]A + Crys and IP/IP + B[g,h,i]P, were calculated. The results suggest that Q. ilex leaves are effective biomonitors of PAH air contamination: in fact, a great PAH accumulation in leaves from the urban areas, until 30-time higher compared to those from the remote sites, has been observed. At each site, the similar total PAH concentrations in leaves of different age, probably due to a canopy effect, indicate an ability of all leaf age classes to monitor local PAH concentrations in air, remarking practical implications for air biomonitoring. The findings suggest that PAH adsorption in Q. ilex leaves does not result limited by leaf lipid content. Moreover, this study demonstrates the source-diagnostic potential of Q. ilex leaves, because, in particular, the Flt/Flt + Pyr and IP/IP + B[g,h,i]P ratios indicate vehicular traffic as the main source of PAHs in the urban areas and wood combustion in the remote areas. Moreover, to distinguish biomass combustion source, a promising tracer PAH as DB[a,h]A could be used. The high contribution of DB[a,h]A to total PAH concentrations at the remote sites determines a high carcinogenic potential in this area, similar to that calculated for the urban area where the carcinogenic PAH concentrations in absolute values are often higher.

Abstract Objectives. To explore general practitioners’ (GPs’) specific negotiation strategies regarding sick-leave issues with patients suffering from subjective health complaints. Design. Focus-group study. Setting. Nine focus-group interviews in three cities in different regions of Norway. Participants. 48 GPs (31 men, 17 women; age 32–65), participating in a course dealing with diagnostic practice and assessment of sickness certificates related to patients with subjective health complaints. Results. The GPs identified some specific strategies that they claimed to apply when dealing with the question of sick leave for patients with subjective health complaints. The first step would be to build an alliance with the patient by complying with the wish for sick leave, and at the same time searching for information to acquire the patient's perspective. This position would become the basis for the main goal: motivating the patient for a rapid return to work by pointing out the positive effects of staying at work, making legal and moral arguments, and warning against long-term sick leave. Additional solutions might also be applied, such as involving other stakeholders in this process to provide alternatives to sick leave. Conclusions and implications. GPs seem to have a conscious approach to negotiations of sickness certification, as they report applying specific strategies to limit the duration of sick leave due to subjective health complaints. This give-and-take way of handling sick-leave negotiations has been suggested by others to enhance return to work, and should be further encouraged. However, specific effectiveness of this strategy is yet to be proven, and further investigation into the actual dealings between doctor and patients in these complex encounters is needed.

Whole-leaf wash improves chlorine efficacy for microbial reduction and prevents pathogen cross-contamination during fresh-cut lettuce processing.

Nou, Xiangwu; Luo, Yaguang

2010-06-01

Currently, most fresh-cut processing facilities in the United States use chlorinated water or other sanitizer solutions for microbial reduction after lettuce is cut. Freshly cut lettuce releases significant amounts of organic matter that negatively impacts the effectiveness of chlorine or other sanitizers for microbial reduction. The objective of this study is to evaluate whether a sanitizer wash before cutting improves microbial reduction efficacy compared to a traditional postcutting sanitizer wash. Romaine lettuce leaves were quantitatively inoculated with E. coli O157:H7 strains and washed in chlorinated water before or after cutting, and E. coli O157:H7 cells that survived the washing process were enumerated to determine the effectiveness of microbial reduction for the 2 cutting and washing sequences. Whole-leaf washing in chlorinated water improved pathogen reduction by approximately 1 log unit over traditional cut-leaf sanitization. Similar improvement in the reduction of background microflora was also observed. Inoculated "Lollo Rossa" red lettuce leaves were mixed with noninoculated Green-Leaf lettuce leaves to evaluate pathogen cross-contamination during processing. High level (96.7% subsamples, average MPN 0.6 log CFU/g) of cross-contamination of noninoculated green leaves by inoculated red leaves was observed when mixed lettuce leaves were cut prior to washing in chlorinated water. In contrast, cross-contamination of noninoculated green leaves was significantly reduced (3.3% of subsamples, average MPN

Automating digital leaf measurement: the tooth, the whole tooth, and nothing but the tooth.

Many species of plants produce leaves with distinct teeth around their margins. The presence and nature of these teeth can often help botanists to identify species. Moreover, it has long been known that more species native to colder regions have teeth than species native to warmer regions. It has therefore been suggested that fossilized remains of leaves can be used as a proxy for ancient climate reconstruction. Similar studies on living plants can help our understanding of the relationships. The required analysis of leaves typically involves considerable manual effort, which in practice limits the number of leaves that are analyzed, potentially reducing the power of the results. In this work, we describe a novel algorithm to automate the marginal tooth analysis of leaves found in digital images. We demonstrate our methods on a large set of images of whole herbarium specimens collected from Tilia trees (also known as lime, linden or basswood). We chose the genus Tilia as its constituent species have toothed leaves of varied size and shape. In a previous study we extracted c.1600 leaves automatically from a set of c.1100 images. Our new algorithm locates teeth on the margins of such leaves and extracts features such as each tooth's area, perimeter and internal angles, as well as counting them. We evaluate an implementation of our algorithm's performance against a manually analyzed subset of the images. We found that the algorithm achieves an accuracy of 85% for counting teeth and 75% for estimating tooth area. We also demonstrate that the automatically extracted features are sufficient to identify different species of Tilia using a simple linear discriminant analysis, and that the features relating to teeth are the most useful.

Retaining early career registered nurses: a case study.

2016-01-01

A core objective of the Australian health system is to provide high quality, safe health care that meets the needs of all Australians. To achieve this, an adequate and effective workforce must support the delivery of care. With rapidly changing health care systems and consumer demographics, demand for care is increasing and retention of sufficient numbers of skilled staff is now a critical priority to meet current and future health care demands. Nurses are the largest cohort of professionals within the health workforce. Reducing the rates at which nurses leave the profession and supporting nurses to practice in their profession longer will have beneficial implications for the sustainability of a nursing workforce and, ultimately, to patient outcomes. The aim of the study was to describe and explain early career registered nurses' (ECRNs) experiences and support requirements during the first five years of practice for the purposes of identifying strategies that would support greater retention of ECRNs. A single case study design focused on early career registered nurses (ECRNs) working in a hospital and health service in northern Australia. The research team adopted Djukic et al's definition of ECRNs as "RNs who have practiced for less than 5 years". Data was collected via three individual interviews and two focus groups. Thirty-five ECRNs participated in the study. Qualitative analysis of data generated during interviews and focus groups, identified the key themes of receiving career advice and choice or no choice . Analysis of study data in the context of the broader literature resulted in the researchers identifying six areas of focus for ECRN retention: 1) well-planned, supported and structured transition periods; 2) consideration of rotation through different areas with a six month minimum for skills development; 3) empowering decision making; 4) placement opportunities and choice in decisions of where to work; 5) career advice and support that considers ECRNs' personalities and skills; and 6) encouragement to reflect on career choices. Reducing turnover and improving retention relies on understanding the factors that influence nurses' decisions to leave or remain within an organisation and the profession. Ensuring nurses in the current workforce remain engaged and productive, rather than leave the profession, is reliant on addressing factors that cause attrition and implementing strategies that strengthen retention rates and workforce sustainability.

The practice of research is full of ethical challenges, many of which might be addressed through the teaching of responsible conduct of research (RCR). Although such training is increasingly required, there is no clear consensus about either the goals or content of an RCR curriculum. The present study was designed to assess community standards in three domains of research practice: authorship, collaboration, and data management. A survey, developed through advice from content matter experts, focus groups, and interviews, was distributed in November 2010 to U.S. faculty from 50 graduate programs for each of four different disciplines: microbiology, neuroscience, nursing, and psychology. The survey addressed practices and perceived standards, as well as perceptions about teaching and learning. Over 1,300 responses (response rate of 21 %) yielded statistically significant differences in responses to nearly all questions. However the magnitude of these differences was typically small, leaving little reason to argue for community consensus on standards. For nearly all questions asked, the clear finding was that there was nothing approaching consensus. These results may be useful not so much to teach what the standards are, but to increase student awareness of the diversity of those standards in reported practice.

To examine if differences exist in the levels of autonomy and job satisfaction among primary care nurse practitioners (NPs) employed in retail clinics versus traditional primary care settings. Data were collected from 310 primary care NPs who attended the American Association of NP's 28th Annual Conference in June 2013. Participants completed a demographic form, the Misener NP Job Satisfaction Scale, and the Dempster Practice Behavior Scale. Overall, there were no differences in job satisfaction or autonomy among NPs by practice setting. Retail NPs felt less valued and were less satisfied with social interaction, but more satisfied with benefits compared to NPs in traditional settings. NPs working in retail clinics were less likely to have intentions to leave current position compared to NPs in traditional practice settings. The results of this study enhance our current understanding of the linkages between levels of autonomy, job satisfaction, and practice setting among primary care NPs. The findings of this descriptive study offer valuable insights for stakeholders devoted to the development of the primary care workforce and identify modifiable factors that may influence retention and turnover rates among NPs. ©2015 American Association of Nurse Practitioners.

Photo-oxidative stress in emerging and senescing leaves: a mirror image?

2013-08-01

The life cycle of a leaf can be characterized as consisting of different stages: from primordial leaf initiation in the shoot apical meristem (SAM) to leaf senescence. Leaf development, from early leaf growth to senescence, is tightly controlled by plant development and the environment. Here, we primarily focus on summarizing current evidence indicating that photo-oxidative stress occurs at the two extremes of a leaf's lifespan. Some recent studies clearly indicate that--as happens in senescing leaves--emerging new leaves suffer from photo-oxidative stress, which suggests that oxidative stress plays a key role at both ends of the leaf life cycle. We discuss the causes and consequences of suffering from photo-oxidative stress during leaf development, paying attention to the particularities of this process at the two extremes of leaf development. Of particular importance is the current evidence showing mechanisms that maintain an adequate cellular reactive oxygen species/antioxidant (redox) balance that allows growth and prevents oxidative damage in young emerging leaves, while later on photo-oxidative stress induces cell death in senescing leaves. Also of interest is the fact that reductions in the efficiency of photosystem II photochemistry may not necessarily indicate photo-oxidative stress in emerging leaves. In this review, we summarize current knowledge of photoinhibition, photoprotection, and photo-oxidative stress at the two ends of the leaf life cycle: early leaf growth and leaf senescence.

The light environment of forest canopies is complex leading to differentiation in morphological development and alteration of physiological processes that are important for the proper combination of genotype and site factors to maximize final yield. To select leaves and plants of a uniform age plastochron and leaf plastochron indices were developed for American sycamore Platanus occidentalis L. The application of these indices was useful in selecting a population of plants of uniform age and, morphological development, and useful in selecting leaves of uniform age within the zone of leaf development. Labeling studies in which leaves of specific ages were fedmore » /sup 14/CO/sub 2/ indicated that leaves of this species undergo transitions in degree and direction of export. Acropetal export of photosynthates conforms to a phyllotactic sequence, suggesting a relationship between arrangement of vascular bundles and phyllotaxy. Examination of the /sup 14/CO/sub 2/ labeling patterns in source leaves (LPI 2.0) showed rapid incorporation of label into amino acid, sugar, and organic acid chemical pools that can be used to in situ synthesis of proteins, lipids, and other structural components. However as the irradiance regime under which the plants were grown decreased, leaves partitioned more fixed /sup 14/CO/sub 2/ into starch than into the water soluble fraction from which metabolic and structural components as well as a transport species could be synthesized.« less

Succession Planning and Management Practice in Washington State Local Public Health Agencies.

Turnover of top local public health officials is expected to be great, with 23% being 60 years of age or older, and another 42% being 50 to 59 years of age. Yet, we know little about the use of succession planning in public health agencies. Describe succession planning practices in local public health agencies. We conducted a Web-based, cross-sectional survey of succession planning practices and followed the career paths of public health officials for 40 months. The top local public health officials from Washington State's 35 local governmental public health agencies. Twenty-five succession planning best practices. All 35 agencies responded, resulting in a 100% response rate. Our study found evidence of succession planning practices in Washington State local public health agencies: 85% of agencies selected high-performing high potential employees for development, 76% sent them to formal technical and management/leadership training, 70% used cross-functional team projects, and 67% used stretch assignments to develop their employees. Impetuses to implement succession planning were discovering that large percentages of employees were able to retire soon and that national accreditation requires workforce development plans. Barriers to implementing succession planning included other competing demands for time, belief that the agency's workforce was too small for a formal program, and concerns that there would be union barriers. In 2012, 50% of the officials surveyed said that it would be at least possible that they would leave their current jobs within 5 years. Forty months later, 12 (34%) had left their positions. We were encouraged by the level of succession planning in Washington State and recommend creating a greater sense of urgency by focusing on agency retirement profiles and emphasizing the need for workforce development plans for accreditation. Developing the public health leaders of tomorrow is too important to be left to chance.

EIA screening and nature protection in Denmark.

PubMed

Christensen, Per; Kørnøv, Lone

2011-04-01

The number of environmental impact assessment (EIA) screenings in Denmark has increased dramatically since 2000. This is a consequence of increased pig production as well as the concentration of production on larger farms. In the same period, EIA rules have developed primarily due to an increased focus on the protection of groundwater and Natura 2000 sites. In particular, the implementation of Natura 2000 in Danish legislation has increased the demands on many farms. In its rulings on appealed cases, the Nature Protection Board of Appeal has strengthened its demands, and this is mirrored in screening practices. In this paper, the demands formulated in the guidelines of local authorities were analysed in order to investigate how the protection of groundwater, coastal waters, lakes and Natura 2000 sites develops through EIA screening. It is concluded that the level of protection has improved, and that the main cause for this is not EIA regulations as such, but the positive role which the implementation of the Natura 2000 objectives has played in this development. However, it was also found that the formulation of demands varies greatly between the counties, thus often resulting in ambiguity and leaving room for quite different practices in different counties.

Helminth ova control in wastewater and sludge for advanced and conventional sanitation.

2007-01-01

Worldwide, the most important reuse of wastewater, in volume, is agricultural irrigation. Therefore, there is a need to properly treat wastewater for such purpose, considering the removal of pathogens while leaving suitable amounts of nutrients and other compounds to increase productivity. Helminth ova are one of the main targeted pathogens in the new guidelines for water reuse in agriculture and aquaculture issued in 2006 by the World Health Organization. However, relatively little research has been done recently on how to remove and inactivate helminth ova from wastewater and sludge and recommendations given several decades ago are still used, but when put into practice, particularly in developing countries, produce unsatisfactory results. One problem is that these criteria were developed using inaccurate analytical techniques and the other is the large number and variety of helminth ova species found in wastewater and sludge from the developing world. In fact, the few technological options to remove and inactivate helminth ova come from research performed using wastewater and sludge with low helminth ova content, and refer almost only to Ascaris (one type of helminth). This paper summarises recent research work and results from practical experience concerning helminth ova control for advanced and conventional sanitation.

Insect eggs protected from high temperatures by limited homeothermy of plant leaves.

Potter, Kristen; Davidowitz, Goggy; Woods, H Arthur

2009-11-01

Virtually all aspects of insect biology are affected by body temperature, and many taxa have evolved sophisticated temperature-control mechanisms. All insects, however, begin life as eggs and lack the ability to thermoregulate. Eggs laid on leaves experience a thermal environment, and thus a body temperature, that is strongly influenced by the leaves themselves. Because plants can maintain leaf temperatures that differ from ambient, e.g. by evapotranspiration, plant hosts may protect eggs from extreme ambient temperatures. We examined the degree to which leaves buffer ambient thermal variation and whether that buffering benefits leaf-associated insect eggs. In particular, we: (1) measured temperature variation at oviposition sites in the field, (2) manipulated temperatures in the laboratory to determine the effect of different thermal conditions on embryo development time and survival, and (3) tested embryonic metabolic rates over increasing temperatures. Our results show that Datura wrightii leaves buffer Manduca sexta eggs from fatally high ambient temperatures in the southwestern USA. Moreover, small differences in temperature profiles among leaves can cause large variation in egg metabolic rate and development time. Specifically, large leaves were hotter than small leaves during the day, reaching temperatures that are stressfully high for eggs. This study provides the first mechanistic demonstration of how this type of leaf-constructed thermal refuge interacts with egg physiology.

Metagenomic Analysis of Fungal Diversity on Strawberry Plants and the Effect of Management Practices on the Fungal Community Structure of Aerial Organs

2016-01-01

An amplicon metagenomic approach based on the ITS2 region of fungal rDNA was used to identify the composition of fungal communities associated with different strawberry organs (leaves, flowers, immature and mature fruits), grown on a farm using management practices that entailed the routine use of various chemical pesticides. ITS2 sequences clustered into 316 OTUs and Ascomycota was the dominant phyla (95.6%) followed by Basidiomycota (3.9%). Strawberry plants supported a high diversity of microbial organisms, but two genera, Botrytis and Cladosporium, were the most abundant, representing 70–99% of the relative abundance (RA) of all detected sequences. According to alpha and beta diversity analyses, strawberry organs displayed significantly different fungal communities with leaves having the most diverse fungal community, followed by flowers, and fruit. The interruption of chemical treatments for one month resulted in a significant modification in the structure of the fungal community of leaves and flowers while immature and mature fruit were not significantly affected. Several plant pathogens of other plant species, that would not be intuitively expected to be present on strawberry plants such as Erysiphe, were detected, while some common strawberry pathogens, such as Rhizoctonia, were less evident or absent.

2016-12-01

Growing energy demands and concerns for climate change have urgently pushed forward the timeline for the implementation of biofuel energies. Switchgrass (Panicum virgatum) is a leading biofuel crop in the United States. Bacteria living on and inside leaves and roots affect plant health, hence a plant's genetic control over its microbiota is of great interest to crop breeders and evolutionary biologists. We present a large-scale field experiment to untangle the effects of genotype, environment, soil horizon and harvest treatment practices on prokaryotic and fungal communities associated with leaves and roots of switchgrass. Using V4 16S rRNA and ITS gene as well as metagenome sequencing, we show that host genotype is significant in both, leaves and roots, and varies among sites. Microbiome composition along the rhizosphere also shifts with soil depth. Furthermore, plant harvest significantly changes both, leaf surface and rhizosphere communities, which can be seen a year after the harvest event. Gene function analysis shows that rhizosphere communities are enriched in genes encoding nitrate reduction, carbohydrate transport and metabolism, motility, and sensory and signal transduction proteins relative to leaf surface communities. Our results demonstrate how genotype-environment interactions contribute to the complexity of microbiome assembly in natural environments.

Ethnoveterinary practices are locally available and affordable to Fulani pastoralists in Niger State, Nigeria, to whom conventional veterinary services are often not readily available and are relatively expensive. This study was designed to identify and document medicinal plant and nonplant materials used by this group in the management of cattle diseases. Participatory rural appraisal tools of checklist, semistructured interview, probing, transect, and triangulations were used to assess Fulani pastoralists existing knowledge on traditional veterinary practices in nine pastoral communities spread across the state. Fifty medicinal materials and seven traditional preventive practices are in use against CBPP and other cattle disease conditions. Of these, 38 (76.0%) are medicinal plants and 12 (24.0%) are nonplant materials (edible earth materials and minerals). Family Fabaceae was most commonly mentioned while leaves were the most common parts used. Most of these materials are administered by drenching with few others mixed with feed. Proportions of plant parts used include leaves (47.4%), barks (31.6%), roots (10.6%), and 2.6% of each of rhizomes, fruits, seeds, and whole plants. Of recently used ingredients are kerosene and spent engine oil. Further research into the active ingredients of ethnoveterinary materials and dosages is necessary to guide their usage. PMID:26464953

All second and third year general practice vocational trainees in the Irish Republic in 1991 were invited to complete a questionnaire concerning the hospital component of their training. The questionnaire was based on specific recommendations published by the I.C.G.P. regarding hospital training posts. Replies were received from 39 trainees constituting 70% of the total number of eligible trainees. In general, hospital posts were perceived to be of relevance and to offer adequate exposure to outpatient management and to the development of useful practical skills. More than 70% of the trainees were free to attend at least 75% of the study release course. Everyone entitled to study leave for examination purposes obtained it. However, 95% of trainees found their hospital teachers unfamiliar with the aims and objectives of Vocational Training. Two-thirds of trainees received less than two hours a week of formal or informal teaching. More than two-thirds did not participate in an introductory general practice period and less than a quarter had their individual needs assessed early on. Substantial realisation of the guidelines issued by the ICGP has been achieved. Further work is necessary in the areas of individual needs assessment, relevant structured teaching and general practice liaison. Three specific recommendations are made to achieve these aims.

Motives for early retirement of self-employed GPs in the Netherlands: a comparison of two time periods

PubMed Central

2012-01-01

Background The high cost of training and the relatively long period of training for physicians make it beneficial to stimulate physicians to retire later. Therefore, a better understanding of the link between the factors influencing the decision to retire and actual turnover would benefit policies designed to encourage later retirement. This study focuses on actual GP turnover and the determining factors for this in the Netherlands. The period 2003–2007 saw fewer GPs retiring from general practice than the period 1998–2002. In addition, GPs’ retirement age was higher in 2003–2007. For these two periods, we analysed work perception, objective workload and reasons for leaving, and related these with the probability that GPs would leave general practice at an early age. Methods In 2003, a first retrospective survey was sent to 520 self-employed GPs who had retired between 1998 and 2002. In 2008, the same survey was sent to 405 GPs who had retired between 2003 and 2007. The response rates were 60% and 54%, respectively. Analyses were done to compare work perception, objective workload, external factors and personal reasons for retiring. Results For both male and female GPs, work perception was different in the periods under scrutiny: both groups reported greater job satisfaction and a lower degree of emotional exhaustion in the later period, although there was no notable difference in subjective workload. The objective workload was lower in the second period. Moreover, most external factors and personal reasons that may contribute to the decision to retire were reported as less important in the second period. There was a stronger decrease in the probability that female GPs leave general practice within one year than for male GPs. This underscores the gender differences and the need for disaggregated data collection. Conclusions The results of this study suggest that the decrease in the probability of GPs leaving general practice within one year and the increasing retirement age are caused by a decrease in the objective workload, a change in GPs’ work perception, external factors and personal reasons. Based on the results of this study, we consider workload reduction policies are the most useful instruments to control retention and retirement. PMID:23249631

Rural veterinary services in Western Australia: Part B. Rural practice.

To determine the current status of rural veterinary services in Western Australia. A questionnaire was sent to all eligible rural practitioners registered in 2006 and the replies were transferred to Microsoft Excel for analysis. Of the rural practitioners invited to participate in the survey replies were received from 67%. There were equal numbers of females and males. Their mean age was 44 years. Ninety per cent of respondents considered knowledge gained as an undergraduate was sufficient to equip them for practice, but only 60% considered their practical skills adequate. Thirteen per cent of those in rural practices in 2005 had left by 2006. Eighty-nine per cent of respondents were in mixed practice, the balance in specific species practice, such as equine, large animal and production animal consultancy. The majority of rural practitioners relied on servicing companion animals for their viability; 7% earned their income from servicing production animals only. Seventy per cent utilised merchandising and the sale of pet foods to supplement the income received from the traditional veterinary services and 34% found it necessary to earn an independent income. A quarter considered that rural practice did not have a future. The majority of rural practitioners in Western Australia depend on companion animals, not production animals, to remain viable, with very few operating production animal services. Poor remuneration is a major reason why veterinarians leave rural practice, and many find it necessary to supplement their income or develop an independent income.

Do perceived high performance work systems influence the relationship between emotional labour, burnout and intention to leave? A study of Australian nurses.

The purpose of this article was to explore the relationships between perceived high performance work systems, emotional labour, burnout and intention to leave among nurses in Australia. Previous studies show that emotional labour and burnout are associated with an increase in intention to leave of nurses. There is evidence that high performance work systems are in association with a decrease in turnover. There are no previous studies that examine the relationship between high performance work systems and emotional labour. A cross-sectional, correlational survey. The study was conducted in Australia in 2008 with 183 nurses. Three hypotheses were tested with validated measures of emotional labour, burnout, intention to leave, and perceived high performance work systems. Principal component analysis was used to examine the structure of the measures. The mediation hypothesis was tested using Baron and Kenny's procedure and the moderation hypothesis was tested using hierarchical regression and the product-term. Emotional labour is positively associated with both burnout and intention to leave. Burnout mediates the relationship between emotional labour and intention to leave. Perceived high performance work systems negatively moderates the relationship between emotional labour and burnout. Perceived high performance work systems not only reduces the strength of the negative effect of emotional labour on burnout but also has a unique negative effect on intention to leave. Ensuring effective human resource management practice through the implementation of high performance work systems may reduce the burnout associated with emotional labour. This may assist healthcare organizations to reduce nurse turnover. © 2012 Blackwell Publishing Ltd.

Fungal colonization, succession, and decomposition of leaves and stems of Salix arctica were studied to estimate the roles of fungi in the decomposition processes in the high Arctic. The samples were collected from five moraines with different periods of development since deglaciation to investigate the effects of ecosystem development on the decomposition processes during the primary succession. The total hyphal lengths and the length of darkly pigmented hyphae increased during decomposition of leaves and stems and were not varied with the moraines. Four fungal morphotaxa were frequently isolated from both leaves and stems. The frequencies of occurrence of two morphotaxa varied with the decay class of leaves and/or stems. The hyphal lengths and the frequencies of occurrence of fungal morphotaxa were positively or negatively correlated with the contents of organic chemical components and nutrients in leaves and stems, suggesting the roles of fungi in chemical changes in the field. Pure culture decomposition tests demonstrated that the fungal morphotaxa were cellulose decomposers. Our results suggest that fungi took part in the chemical changes in decomposing leaves and stems even under the harsh environment of the high Arctic.

Nitrogen is a necessary and important element for the growth and development of fruit orchards. Timely, accurate and nondestructive monitoring of nitrogen status in fruit orchards would help maintain the fruit quality and efficient production of the orchard, and mitigate the pollution of water resources caused by excessive nitrogen fertilization. This study investigated the capability of hyperspectral imagery for estimating and visualizing the nitrogen content in citrus canopy. Hyperspectral images were obtained for leaf samples in laboratory as well as for the whole canopy in the field with ImSpector V10E (Spectral Imaging Ltd., Oulu, Finland). The spectral datas for each leaf sample were represented by the average spectral data extracted from the selected region of interest (ROI) in the hyperspectral images with the aid of ENVI software. The nitrogen content in each leaf sample was measured by the Dumas combustion method with the rapid N cube (Elementar Analytical, Germany). Simple correlation analysis and the two band vegetation index (TBVI) were then used to develop the spectra data-based nitrogen content prediction models. Results obtained through the formula calculation indicated that the model with the two band vegetation index (TBVI) based on the wavelengths 811 and 856 nm achieved the optimal estimation of nitrogen content in citrus leaves (R2 = 0.607 1). Furthermore, the canopy image for the identified TBVI was calculated, and the nitrogen content of the canopy was visualized by incorporating the model into the TBVI image. The tender leaves, middle-aged leaves and elder leaves showed distinct nitrogen status from highto low-levels in the canopy image. The results suggested the potential of hyperspectral imagery for the nondestructive detection and diagnosis of nitrogen status in citrus canopy in real time. Different from previous studies focused on nitrogen content prediction at leaf level, this study succeeded in predicting and visualizing the nutrient content of fruit trees at canopy level. This would provide valuable information for the implementation of individual tree-based fertilization schemes in precision orchard management practices.

Metallic stents are commonly used in many clinical applications including peripheral vascular disease intervention, biliary obstruction, endovascular repair of aneurysms, and percutaneous coronary interventions. In the examination of vascular stent placement, it is important to determine if the stent is open or has become obstructed. This is increasingly important in the era of drug-eluting stent usage in coronary arteries. We describe a practical, rapid and cost-effective method to dissolve most metallic stents leaving the vascular and luminal tissues intact. This practical method may replace the laborious and expensive plastic embedding methods currently utilized.

The global problem of drought threatens agricultural production and constrains the development of sustainable agricultural practices. In plants, excessive water loss causes drought stress and induces early senescence. In this study, we isolated a rice (Oryza sativa) mutant, designated as early senescence1 (es1), which exhibits early leaf senescence. The es1-1 leaves undergo water loss at the seedling stage (as reflected by whitening of the leaf margin and wilting) and display early senescence at the three-leaf stage. We used map-based cloning to identify ES1, which encodes a SCAR-LIKE PROTEIN2, a component of the suppressor of cAMP receptor/Wiskott-Aldrich syndrome protein family verprolin-homologous complex involved in actin polymerization and function. The es1-1 mutants exhibited significantly higher stomatal density. This resulted in excessive water loss and accelerated water flow in es1-1, also enhancing the water absorption capacity of the roots and the water transport capacity of the stems as well as promoting the in vivo enrichment of metal ions cotransported with water. The expression of ES1 is higher in the leaves and leaf sheaths than in other tissues, consistent with its role in controlling water loss from leaves. GREEN FLUORESCENT PROTEIN-ES1 fusion proteins were ubiquitously distributed in the cytoplasm of plant cells. Collectively, our data suggest that ES1 is important for regulating water loss in rice.

2017-01-01

Background: To study the chemical constituents and larvicidal activity of essential oil extracted from the leaves of Coccinia grandis against three mosquito species. Methods: Essential oil was extracted by hydro distillation using clevenger apparatus and was analyzed for chemical constituents by gas chromatography-mass spectrophotometry (GC-MS). Larvicidal activity was recorded after 12 and 24h of post-exposure against three mosquito species, Anopheles stephensi, Aedes aegypti and Culex quinquefasciatus. Dead larvae were identified when they failed to move after probing with a needle in the siphon or cervical region. The LC50 and LC90 values for three mosquito larvae were calculated by Probit analysis. Results: The GC-MS analysis revealed that essential oil contains 23 different constituents. Out of these 23 constituents, major constituents identified were n-tetracosane (39.18%), n-eicosane (30.04%), tetratriacotane (2.97%), 7-octadecanal (2.81%), and tricosane (2.31%). Essential oil from leaves of Coccinia grandis exhibited significant larvicidal activity against An. stephensi with LC50 and LC90 values 39.41ppm and 123.24ppm, respectively. This was followed by Ae. aegypti and Cx. quinquefasciatus with LC50 and LC90 values of 48.20ppm, 131.84ppm and 52.80ppm, 135.48ppm, respectively after 24h of exposure. Conclusion: The results could be useful in developing a cost effective, ecofriendly, region specific and practical strategy for the control of mosquito vectors. PMID:29062847

A molecular basis behind heterophylly in an amphibious plant, Ranunculus trichophyllus

Ranunculus trichophyllus is an amphibious plant that produces thin and cylindrical leaves if grown under water but thick and broad leaves if grown on land. We found that such heterophylly is widely controlled by two plant hormones, abscisic acid (ABA) and ethylene, which control terrestrial and aquatic leaf development respectively. Aquatic leaves produced higher levels of ethylene but lower levels of ABA than terrestrial leaves. In aquatic leaves, their distinct traits with narrow shape, lack of stomata, and reduced vessel development were caused by EIN3-mediated overactivation of abaxial genes, RtKANADIs, and accompanying with reductions of STOMAGEN and VASCULAR-RELATED NAC-DOMAIN7 (VDN7). In contrast, in terrestrial leaves, ABI3-mediated activation of the adaxial genes, RtHD-ZIPIIIs, and STOMAGEN and VDN7 established leaf polarity, and stomata and vessel developments. Heterophylly of R.trichophyllus could be also induced by external cues such as cold and hypoxia, which is accompanied with the changes in the expression of leaf polarity genes similar to aquatic response. A closely-related land plant R. sceleratus did not show such heterophyllic responses, suggesting that the changes in the ABA/ethylene signaling and leaf polarity are one of key evolutionary steps for aquatic adaptation.

An ipt gene under control of the senescence-specific SAG12 promoter from Arabidopsis (PSAG12-IPT) significantly delayed developmental and postharvest leaf senescence in mature heads of transgenic lettuce (Lactuca sativa L. cv Evola) homozygous for the transgene. Apart from retardation of leaf senescence, mature, 60-d-old plants exhibited normal morphology with no significant differences in head diameter or fresh weight of leaves and roots. Induction of senescence by nitrogen starvation rapidly reduced total nitrogen, nitrate, and growth of transgenic and azygous (control) plants, but chlorophyll was retained in the lower (outer) leaves of transgenic plants. Harvested PSAG12-IPT heads also retained chlorophyll in their lower leaves. During later development (bolting and preflowering) of transgenic plants, the decrease in chlorophyll, total protein, and Rubisco content in leaves was abolished, resulting in a uniform distribution of these components throughout the plants. Homozygous PSAG12-IPT lettuce plants showed a slight delay in bolting (4–6 d), a severe delay in flowering (4–8 weeks), and premature senescence of their upper leaves. These changes correlated with significantly elevated concentrations of cytokinin and hexoses in the upper leaves of transgenic plants during later stages of development, implicating a relationship between cytokinin and hexose concentrations in senescence.

The host selection for oviposition by Spodoptera frugiperda (J.E. Smith) among corn, millet, cotton and soybean, and its relationship with the biological characteristics were investigated. Free and non-choice tests for oviposition using plots containing five plants each, from each host in plastic greenhouse, resulted in similar oviposition preference among the host plants. In addition, selected biological characteristics of S. frugiperda were determined in the laboratory with larvae feeding on host leaves, and the combination of leaf and cotton boll. Neonate larvae exhibited low success of colonization on cotton boll compared to the leaves of all other hosts. Spodoptera frugiperda fed only on cotton bolls exhibited longer larval and pupal development, and longer adult life span; however with similar egg production. Larvae fed cotton leaves during six days and then transferred to cotton bolls, however, exhibited development and reproduction similar to those reared on corn or only on cotton leaves. Therefore, the variations on immature stages of S. frugiperda were not related with host selection for oviposition which was similar among the studied hosts. Based on our data, the millet as a winter, rotational, and cover crop is a potential host for S. frugiperda, while leaves and cotton bolls were diets of intermediate suitability as compared to corn and soybean leaves.

The ethics of forensic practice: reclaiming the wasteland.

PubMed

Morse, Stephen J

2008-01-01

After beginning with a warm appreciation of Alan Stone's scholarship and character, this article argues that Stone's woeful characterization of forensic practice as a wasteland that has no genuine ethical guide to practice and little to contribute is vastly overstated. It claims that the basis for useful ethical practice is rooted in a proper understanding of the law's folk psychological model of behavior and criteria. Then it suggests the proper bounds of forensic practice, including an aspirational list of do's and don'ts. The view presented is deflationary and cautious compared to what the law permits and most practitioners do, but it still leaves forensic practitioners with a wide and important role in the legal system.

Organizational climate and hospital nurses' caring practices: a mixed-methods study.

Organizational climate in healthcare settings influences patient outcomes, but its effect on nursing care delivery remains poorly understood. In this mixed-methods study, nurse surveys (N = 292) were combined with a qualitative case study of 15 direct-care registered nurses (RNs), nursing personnel, and managers. Organizational climate explained 11% of the variation in RNs' reported frequency of caring practices. Qualitative data suggested that caring practices were affected by the interplay of organizational climate dimensions with patients and nurses characteristics. Workload intensity and role ambiguity led RNs to leave many caring practices to practical nurses and assistive personnel. Systemic interventions are needed to improve organizational climate and to support RNs' involvement in a full range of caring practices. © 2014 Wiley Periodicals, Inc.

Controlled environment life support system: Calcium-related leaf injuries on plants

NASA Technical Reports Server (NTRS)

Tibbitts, T. W.

1985-01-01

A calcium related injury in lettuce termed tipburn was the focus of this study. It affects the young developing leaves as they become enclosed during head formation. It is a good model system to study because the injury can be induced with good predictability and lettuce is one of the crops chosen by the CELSS program for concentrated study. Investigations were undertaken to study a number of different procedures, that would have the potential for encouraging movement of calcium into the young developing leaves and to study the time course and pattern of calcium accumulation in developing leaves to provide a basis for developing effective control procedures for this injury.

Juvenile Rhus glabra leaves have higher temperatures and lower gas exchange rates than mature leaves when compared in the field during periods of high irradiance.

Snider, John L; Choinski, John S; Wise, Robert R

2009-05-01

We sought to test the hypothesis that stomatal development determines the timing of gas exchange competency, which then influences leaf temperature through transpirationally driven leaf cooling. To test this idea, daily patterns of gas exchange and leaflet temperature were obtained from leaves of two distinctively different developmental stages of smooth sumac (Rhus glabra) grown in its native habitat. Juvenile and mature leaves were also sampled for ultrastructural studies of stomatal development. When plants were sampled in May-June, the hypothesis was supported: juvenile leaflets were (for part of the day) from 1.4 to 6.0 degrees C warmer than mature leaflets and as much as 2.0 degrees C above ambient air temperature with lower stomatal conductance and photosynthetic rates than mature leaflets. When measurements were taken from July to October, no significant differences were observed, although mature leaflet gas exchange rates declined to the levels of the juvenile leaves. The gas exchange data were supported by the observations that juvenile leaves had approximately half the number of functional stomata on a leaf surface area basis as did mature leaves. It was concluded that leaf temperature and stage of leaf development in sumac are strongly linked with the higher surface temperatures observed in juvenile leaflets in the early spring possibly being involved in promoting photosynthesis and leaf expansion when air temperatures are cooler.

Correlative controls of senescence and plant death in Arabidopsis thaliana (Brassicaceae).

PubMed

Noodén, L D; Penney, J P

2001-11-01

Like most monocarpic plants, longevity of Arabidopsis thaliana plants is controlled by the reproductive structures; however, they appear to work differently from most dicots studied. Neither male- and female-sterility mutations (ms1-1 and bell1, respectively) nor surgical removal of the stems with inflorescences (bolts) at various stages significantly increased the longevity of individual rosette leaves, yet the mutants and treated plants lived 20-50 d longer, measured by the death of the last rosette and/or the last cauline leaf. A series of growth mutations (clv2-4, clv3-2, det3, vam1 enh, and dark green) also increased plant longevity by 20-30 d but did not delay the overall development of the plants. The mutations prolonged plant life through the production of new leaves and stems with inflorescences (bolts) rather than by extending leaf longevity. In growing stems, the newly-formed leaves may induce senescence in the older leaves; however, removal of the younger leaves did not significantly increase the life of the older leaves on the compressed stems of Arabidopsis. Since plants that produce more bolts also live longer, the reproductive load (dry weight) of the bolts did not seem to drive leaf or whole plant senescence here. The developing reproductive structures caused the death of the plant by preventing regeneration of leaves and bolts, which are green and presumably photosynthetic. They also exerted a correlative control (repression) on the development of additional reproductive structures.

Antecedents of hospital nurses' intention to leave the organization: A cross sectional survey.

Leadership and perceived organizational support inspire trust in the leader and in the organization. Consequently, these aspects may contribute to a reduction in job burnout among nurses and, in the end, of the intention on their part to leave the hospital. It is crucial to develop models in order to simultaneously test the correlations between these relevant psychosocial variables, so that complexity of the nursing work environment may be better understood. We expected to give support to and to further corroborate results in the literature linking perceived leadership style – and particularly servant leadership – perceived organizational support, trust in the leader and in the organization, job burnout among nurses and their subsequent intention to leave the hospital. Cross-sectional study. Two Italian large size public hospitals. Two samples including both graduates and non-graduates members of the nursing staff. Overall mean age was equal to 42.06 years while the general mean for tenure was 12.99 years. Data were collected in 2012. A regression model with latent variables was tested via structural equation modeling using LISREL. The multi-sample procedure was also applied in order to test invariance of results between the two samples. Servant leadership was positively associated with trust in the leader and perceived organizational support was positively associated with trust in the organization. Trust in the leader and trust in the organization displayed a negative correlation with the emotional exhaustion and cynicism factors of job burnout, and a positive correlation with the professional efficacy factor. Furthermore, trust scores mediated the effects of servant leadership and perceived organizational support on job burnout factors. The cynicism factor was negatively associated with intention to leave the organization and it also mediated the effects of both trust in the leader and servant leadership on intention to leave. On the other hand, trust in the organization turned out to be directly and negatively related to intention to leave. Servant leadership and perceived organizational support showed their relevance in the nursing setting. The role of trust in the leader, trust in the organization and job burnout factors as mediating variables received support. Interestingly enough, the higher the cynicism score the higher the intention to leave the hospital. The results achieved may have practical implications not only for recruitment and training of nurse managers but also for hospital management. Copyright © 2015 Elsevier Ltd. All rights reserved.

Alliinase and cysteine synthase transcription in developing garlic (Allium sativum L.) over time.

Garlic is a valuable source of healthy compounds, including secondary metabolites rich in sulphur such as cysteine sulphoxides (CSOs). Here, we present new qRT-PCR assays analysing the transcription of two genes encoding key enzymes in CSO biosynthetic pathways (cysteine synthase and alliinase) in developing garlic. We also identified a set of genes (ACT I, GAPDH, and TUB) to use as transcription normalisation controls. We showed that the (normalised) transcription of both enzymes was highest during sprouting and decreased significantly in fully developed leaves, which are the major CSO-producing organs. Transcriptional activity further declined at the end of the growing season. Different cultivars show similar sulphur metabolism gene expression when European garlics were compared to Chinese and American genotypes. The qRT-PCR assays presented are also suitable for investigating the effects of agricultural practices on CSO formation in garlic to satisfy consumer demands. Copyright © 2017.

The Sustainable development goals (SDGs) have the potential to have a significant impact on maternal and child health through their commitments both to directly addressing health services and to improving factors that form the foundation of social determinants of health. To achieve change at scale, national laws and policies have a critical role to play in implementing the SDGs' commitments. One particular policy that could advance a range of SDGs and importantly improve maternal and infant health is paid parental leave. This article analyzes literature on paid leave and related policies relevant to SDG 1 (poverty), SDG 3 (health), SDG 5 (gender equality), SDG 8 (decent work), and SDG 10 (inequality). In addition, this article presents global data on the prevalence of policies in all 193 UN Member States. A review of the literature finds that paid parental leave may support improvements across a range of SDG outcomes relevant to maternal and child health. Across national income levels, paid leave has been associated with lower infant mortality and higher rates of immunizations. In high-income countries, studies have found that paid leave increases exclusive breastfeeding and may improve women's economic outcomes. However, factors including the duration of leave, the wage replacement rate, and whether leave is made available to both parents importantly shape the impacts of paid leave policies. While most countries now offer at least some paid maternal leave, many provide less than the 6 months recommended for exclusive breastfeeding, and only around half as many provide paternal leave. To accelerate progress on the SDGs' commitments to maternal and child health, we should monitor countries' actions on enacting or strengthening paid leave policies. Further research is needed on the duration, wage replacement rate, and availability of leave before and after birth that would best support both child and parental health outcomes and social determinants of health more broadly. In addition, further work is needed to understand the extent to which paid leave policies extend to the informal economy, where the majority of women and men in low- and middle-income countries work.

The 6b gene in the T-DNA region of the Ti plasmids of Agrobacterium tumefaciens and A. vitis is able to generate shooty calli in phytohormone-free culture of leaf sections of tobacco transformed with 6b. In the present study, we report characteristic morphological abnormalities of the leaves of transgenic tobacco and Arabidopsis that express 6b from pTiAKE10 (AK-6b), and altered expression of genes related to cell division and meristem formation in the transgenic plants. Cotyledons and leaves of both transgenic tobacco and Arabidopsis exhibited various abnormalities including upward curling of leaf blades, and transgenic tobacco leaves produced leaf-like outgrowths from the abaxial side. Transcripts of some class 1 KNOX homeobox genes, which are thought to be related to meristem functions, and cell cycle regulating genes were ectopically accumulated in mature leaves. M phase-specific genes were also ectopically expressed at the abaxial sides of mature leaves. These results suggest that the AK-6b gene stimulates the cellular potential for division and meristematic functions preferentially in the abaxial side of leaves and that the leaf phenotypes generated by AK-6b are at least in part due to such biased cell division during polar development of leaves. The results of the present experiments with a fusion gene between the AK-6b gene and the glucocorticoid receptor gene showed that nuclear import of the AK-6b protein was essential for upward curling of leaves and hormone-free callus formation, suggesting a role for AK-6b in nuclear events.

The general practice (GP) workforce in England is in crisis, reflected in increasing rates of early retirement and intentions to reduce hours of working. This study aimed to investigate underlying factors and how these might be mitigated. GPs in central England were invited to participate in an on-line survey exploring career plans and views and experiences of work-related pressures. Quantitative data were analysed using logistic regression analysis and principal components analysis. Qualitative data were analysed using a thematic framework approach. Of 1,192 GPs who participated, 978 (82.0 %) stated that they intend to leave general practice, take a career break and/or reduce clinical hours of work within the next five years. This included 488 (41.9 %) who intend to leave practice, and almost a quarter (279; 23.2 %) intending to take a career break. Only 67 (5.6 %) planned to increase their hours of clinical work. For participants planning to leave practice, the issues that most influenced intentions were volume and intensity of workload, time spent on "unimportant tasks", introduction of seven-day working and lack of job satisfaction. Four hundred fifty five participants responded to open questions (39128 words in total). The main themes were the cumulative impact of work-related pressures, the changing and growing nature of the workload, and the consequent stress. Reducing workload intensity, workload volume, administrative activities, with increased time for patient care, no out-of-hour commitments, more flexible working conditions and greater clinical autonomy were identified as the most important requirements to address the workforce crisis. In addition, incentive payments, increased pay and protected time for education and training were also rated as important. New models of professionalism and organisational arrangements may be needed to address the issues described here. Without urgent action, the GP workforce crisis in England seems set to worsen.

Background Patient feedback websites or doctor rating websites are increasingly being used by patients to give feedback about their health care experiences. There is little known about why patients in England may give Web-based feedback and what may motivate or dissuade them from giving Web-based feedback. Objective The aim of this study was to explore patients’ views toward giving Web-based feedback and ratings to general practitioners (GPs), within the context of other feedback methods available in primary care in England, and in particular, paper-based feedback cards. Methods A descriptive exploratory qualitative approach using face-to-face semistructured interviews was used in this study. Purposive sampling was used to recruit 18 participants from different age groups in London and Coventry. Interviews were transcribed verbatim and analyzed using applied thematic analysis. Results Half of the participants in this study were not aware of the opportunity to leave feedback for GPs, and there was limited awareness about the methods available to leave feedback for a GP. The majority of participants were not convinced that formal patient feedback was needed by GPs or would be used by GPs for improvement, regardless of whether they gave it via a website or on paper. Some participants said or suggested that they may leave feedback on a website rather than on a paper-based feedback card for several reasons: because of the ability and ease of giving it remotely; because it would be shared with the public; and because it would be taken more seriously by GPs. Others, however, suggested that they would not use a website to leave feedback for the opposite reasons: because of accessibility issues; privacy and security concerns; and because they felt feedback left on a website may be ignored. Conclusions Patient feedback and rating websites as they currently are will not replace other mechanisms for patients in England to leave feedback for a GP. Rather, they may motivate a small number of patients who have more altruistic motives or wish to place collective pressure on a GP to give Web-based feedback. If the National Health Service or GP practices want more patients to leave Web-based feedback, we suggest they first make patients aware that they can leave anonymous feedback securely on a website for a GP. They can then convince them that their feedback is needed and wanted by GPs for improvement, and that the reviews they leave on the website will be of benefit to other patients to decide which GP to see or which GP practice to join.

Theory suggests that the decision to return to employment after childbirth and the decision to breast-feed may be jointly determined. We estimate models of simultaneous equations for two different aspects of the relationship between maternal employment and breast-feeding using 1993-1994 data from the U.S. Food and Drug Administration's Infant Feeding Practices Study. We first explore the simultaneous duration of breast-feeding and work leave following childbirth. We find that the duration of leave from work significantly affects the duration of breast-feeding, but the effect of breast-feeding on work leave is insignificant. We also estimate models of the daily hours of work and breast-feedings at infant ages 3 months and 6 months postpartum. At both times, the intensity of work effort significantly affects the intensity of breast-feeding, but the reverse is generally not found. Competition clearly exists between work and breast-feeding for many women in our sample.

Sclerenchymatous ring as a barrier to phloem feeding by Asian citrus psyllid: Evidence from electrical penetration graph and visualization of stylet pathways

2017-01-01

Asian citrus psyllid (Diaphorina citri) feeding behaviors play a significant role in the transmission of the phloem-limited Candidatus Liberibacter asiaticus (CLas) bacterium that causes the economically devastating citrus greening disease. Sustained phloem ingestion by D. citri on CLas infected plants is required for pathogen acquisition and transmission. Recent studies have shown a fibrous ring of thick-walled sclerenchyma around the phloem in mature, fully expanded citrus leaves that is more prominent on the abaxial compared with the adaxial side. The composition and thickness of this fibrous ring may have an important role in selection of feeding sites by D. citri based on leaf age and leaf surface, which in turn can affect pathogen acquisition and transmission. We measured feeding behavior using electrical penetration graph (EPG) recordings of individual D. citri adults placed on abaxial or adaxial surfaces of young or mature Valencia orange leaves to study the role of the sclerenchymatous ring in modifying D. citri feeding behavior. Feeding sites on the same leaf tissues were then sectioned and examined by epifluorescence microscopy. The duration of phloem ingestion (E2 waveform) by psyllids was significantly reduced on mature compared with young leaves, and on abaxial compared with adaxial leaf surfaces. The longest duration of phloem ingestion was observed from psyllids placed on the adaxial side of young leaves that had the least developed sclerenchyma. Bouts of phloem salivation (E1 waveform), however, were significantly longer on mature leaves compared with young leaves. D. citri adults made consecutive phloem feeding attempts (bouts) on the abaxial side of mature leaves and those bouts resulted in unsuccessful or shorter periods of phloem ingestion. Adults also made more frequent and longer bouts of xylem ingestion on mature leaves compared with adult psyllids placed on young leaves. Epifluorescence microscopy showed that the fibrous ring in young leaves was thinner and autofluoresced in red whereas the ring in mature leaves was thicker and autofluoresced in blue, indicating changes in structure and composition (e.g., lignification) of sclerenchyma correlated with leaf age. Our results support the hypothesis that the presence of a thick, well-developed fibrous ring around phloem tissues of mature leaves acts as a barrier to frequent or prolonged phloem ingestion by D. citri from citrus leaves. This may have an important role in limiting or preventing CLas acquisition and/or transmission by D. citri, and could be used for identification and development of resistant citrus cultivars.

Leaf variations in Elaeagnus angustifolia related to environmental heterogeneity.

Klich

2000-11-01

Elaeagnus angustifolia (Russian olive) is a Eurasian tree that has become naturalized and has invaded zones along watercourses in many arid and semiarid regions of the world. These habitats are characterized by vertical environmental gradients, thus trees must develop some plasticity to adapt to the wide range of site conditions. This study was undertaken to test the hypothesis that variations in leaf anatomy and morphology of E. angustifolia reflect their adaptability to the differences in the microclimate that occur within the canopy of single trees. Foliar architecture, blade and petiole epidermal and internal anatomy were examined in leaves at different canopy positions and related to environmental conditions. Upper sun-leaves are exposed to higher solar irradiance and lower air humidity and are smaller, more slender and thicker than the lower, half-exposed and shade-leaves. Color varies between the leaves at different levels, from silvery grey-green in the upper strata, to dark green in the lower one. Bicolor is more evident in half-exposed and shaded leaves. When compared with the lower half-exposed and shade-leaves, the upper leaves of E. angustifolia have a greater areole density, a higher mesophyll proportion and stomatal density. Trichomes are multicellular, pedestalled, stellate-branched or peltate and their form and density can be associated with leaf color and appearance. The slender petioles of the upper leaves have proportionally more epidermis, collenchyma and phloem and less parenchyma and xylem than those of lower leaves, when observed in transverse sections. Foliar morphological and anatomical variability in E. angustifolia may be considered an adaptive advantage that enables leaves to develop and function in habitats marked by strong variations of solar radiation, air temperature and humidity.

To estimate the prevalence of physician burnout, psychological distress, and its association with selected personal and practice characteristics among pediatric critical care physicians and to evaluate the relationship between burnout and psychological distress. Cross-sectional, online survey. Pediatric critical care practices in the United States. Pediatric critical care physicians. None. A nonrandom sample of 253 physicians completed an online survey consisting of personal and practice characteristics, the Maslach Burnout Inventory, and the General Health Questionnaire. Nearly half of the participants (49%; 95% CI, 43-55%; n = 124) scored high burnout in at least one of the three subscales of the Maslach Burnout Inventory and 21% reported severe burnout. The risk of any burnout was about two times more in women physicians (odds ratio, 1.97; 95% CI, 1.2-3.4). Association between other personal or practice characteristics and burnout was not evident in this study, while regular physical exercise appeared to be protective. One third of all participants (30.5%) and 69% of those who experienced severe burnout screened positive for psychological distress. About 90% of the physicians reporting severe burnout have considered leaving their practice. Burnout is high among pediatric critical care physicians in the United States. About two thirds of the physicians with severe burnout met the screening criteria for psychological distress that suggests possible common mental disorders. Significant percentages of physicians experiencing burnout and considering to leave the profession has major implications for the critical care workforce.

Physicians who serve as public health specialists at public health centers and health departments in local or central government have significant roles because of their public health expertise. The aim of this study is to analyze the retention and career paths of such specialists in Japan. We analyzed the data of seven consecutive surveys, spanning 1994 to 2006. We first analyzed the 2006 survey data by sex, age group, and facility type. We then examined the changes over time in the proportion of physicians working in public health administration agencies. We also examined the distribution of the facility types and specialties in which physicians worked both before beginning and after leaving their jobs. These analyses were performed by using physician registration numbers to cross-link data from two consecutive surveys. The proportion of physicians working in public health administration agencies was 0.7% in 2006. The actual numbers for each survey ranged between 1,800 and 1,900. The overall rate remaining in public health administration agencies during the two-year survey interval was 72.8% for 1994-1996. The ratio declined to 67.2% for 2004-2006. Among younger physicians with 1-10 years of experience, the retention rate showed a sharp decline, dropping from 72.6% to 50.0%. Many of these physicians came from or left for a hospital position, with the proportion entering academic hospital institutions increasing in recent years. In many cases, physicians left or entered internal medicine clinical practices. At present in Japan, the number of physicians who leave and the number who begin a position are almost the same; thus, some of the problems associated with physicians leaving are yet to become apparent. However, the fact that the retention period is shortening for younger physicians may represent a future problem for ensuring the quality of physicians in public health administration agencies. Possible strategies include: increasing the number of physicians entering positions; reducing the number leaving positions; and creating a system where physicians can easily reenter positions after leaving while also establishing a revolving door type of career development system, involving both public health departments and hospital clinical departments.

Who are they and why are they leaving?

NASA Astrophysics Data System (ADS)

Ploegstra, Jeffrey Thomas

Quality science teachers continue to be in short supply in the United States. This shortage can be attributed to a number of factors including a rapidly growing population, low numbers entering the field, retirement, and attrition. The case has been made that teacher shortage issues are most strongly related to teacher attrition. If we intend to address the concern over the supply of highly qualified teachers, we need to understand why teachers leave, who we are losing and how they are different from those who stay in teaching. This study addressed these issues through a mixed methods approach. Surveys of the opinions, beliefs, and experiences of teachers, observations of their teaching performance, and interviews were analyzed to identify significant issues leading to departure from classroom teaching. Analysis of the data consisted of MANOVA, correlation, and Chi-square analysis of the survey instruments and observations comparing leavers and stayers. The interviews and other data were triangulated to develop a number of significant themes related to the underlying causes of teacher attrition. The outcomes of this study lend significant insight into the relationships between teacher characteristics, expectations, experiences, and their decision to continue teaching. Major findings include: (1) The workload of teaching is a significant source of dissatisfaction for all teachers, and leavers describe an inability to balance life and work as a significant factor in their decision to leave; (2) Teachers who intend to leave are generally less satisfied with their teacher education programs; (3) Leavers have higher expectations of themselves and/or expect more recognition; (4) Leavers feel held back as professionals due to a variety of contextual factors; (5) Leavers and stayers are similar in their beliefs and practices; (6) Student interactions are a much more significant factor than previously reported. Leavers generally report more discipline issues and less satisfaction with their interactions with students; (7) Those who choose teaching after pursuing another program of study appear more likely to leave and an orientation towards science rather than the students generally results in a less favorable view of students; (8) Many important contextual factors were not different for leavers and stayers.

Introduction Physicians dedicate substantial time to documentation. Scribes are sometimes used to improve efficiency by performing documentation tasks, although their impacts have not been prospectively evaluated. Our objective was to assess a scribe program’s impact on emergency department (ED) throughput, physician time utilization, and job satisfaction in a large academic emergency medicine practice. Methods We evaluated the intervention using pre- and post-intervention surveys and administrative data. All site physicians were included. Pre- and post-intervention data were collected in four-month periods one year apart. Primary outcomes included changes in monthly average ED length of stay (LOS), provider-specific average relative value units (RVUs) per hour (raw and normalized to volume), self-reported estimates of time spent teaching, self-reported estimates of time spent documenting, and job satisfaction. We analyzed data using descriptive statistics and appropriate tests for paired pre-post differences in continuous, categorical, and ranked variables. Results Pre- and post-survey response rates were 76.1% and 69.0%, respectively. Most responded positively to the intervention, although 9.5% reported negative impressions. There was a 36% reduction (25%–50%; p<0.01) in time spent documenting and a 30% increase (11%–46%, p<0.01) in time spent in direct patient contact. No statistically significant changes were seen in job satisfaction or perception of time spent teaching. ED volume increased by 88 patients per day (32–146, p=0.04) pre- to post- and LOS was unchanged; rates of patients leaving against medical advice dropped, and rates of patients leaving without being seen increased. RVUs per hour increased 5.5% and per patient 5.3%; both were statistically significant. No statistically significant changes were seen in patients seen per hour. There was moderate correlation between changes in ED volume and changes in productivity metrics. Conclusion Scribes were well received in our practice. Documentation time was substantially reduced and redirected primarily to patient care. Despite an ED volume increase, LOS was maintained, with fewer patients leaving against medical advice but more leaving without being seen. RVUs per hour and per patient both increased. PMID:26587079

The authors examine a selected array of agency-influenced work and employment conditions and assess their impact upon social workers' job satisfaction, motivation, and intention to seek new employment. The study makes correlations with past empirical studies on job satisfaction and retention, with staff development concerns as stated in social work administration textbooks, and with conditions subject to administrators' influence. Some specified motivational issues included are salary, fringe benefits, job security, physical surroundings, and safety. The analysis demonstrates the contribution of certain contextual and motivational factors to a prediction of job satisfaction or of intent to leave the organization.

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.

The purpose of this study was to investigate intention to leave in relation to organizational factors and work environments among newly graduated nurses (NGN). A questionnaire was delivered to NGN (n = 762) from baccalaureate programs as well as diploma schools from 19 R-hospitals (R-hospitals were designated as "public medical institutions" by the 1951 Medical Law) in 2010. Spearman's rank correlation coefficients and Mann-Whitney U-test were used to test statistical significance. Only 148 questionnaires were returned for a return rate of 19.4%. The authors found that 8.1% of respondents had a highly to extremely likely desire to leave nursing. Intention to leave was significantly associated with Nursing Work Index total (P < 0.01), social support (P < 0.001), work barriers (P < 0.001), commitment to workplace (P < 0.001), job satisfaction (P < 0.001), and burnout (P < 0.001). Those who graduated from R-schools run by the R-organization had significantly positive impressions of their organizations and significantly lower intentions to leave compared to other graduates. The study results suggest that NGN intention to leave the workplace and nursing predict actual early intention to leave. In order to reduce burnout and turnover, support from colleagues and supervisors appears to be essential in organizational and psychosocial work environments for NGN to experience job satisfaction and be committed to their workplace. The results of this study also suggest that a longitudinal study is needed to reveal the long-term effects of organizational factors and work environments on NGN and how they impact role transition and adaptation of the NGN to professional practice roles. © 2013 The Authors.

The purpose of this research was to examine the knowledge and perceptions of family leave policies and practices among senior leaders including American Association of Medical College members of the Group on Women in Medicine and Science (GWIMS) to identify perceived barriers to career success and satisfaction among female faculty. In 2011 and 2012, GWIMS representatives and senior leaders at 24 medical schools were invited to participate in an interview about faculty perceptions of gender equity and overall institutional climate. An inductive, thematic analysis of the qualitative data was conducted to identify themes represented in participant responses. The research team read and reviewed institutional family leave policies for concordance with key informant descriptions. There were 22 GWIMS representatives and senior leaders in the final sample. Participants were all female; 18 (82%) were full professors with the remainder being associate professors. Compared with publicly available policies at each institution, the knowledge of nine participants was consistent with policies, was discrepant for six, with the remaining seven acknowledging a lack of knowledge of policies. Four major themes were identified from the interview data: 1) Framing family leave as a personal issue undermines its effect on female faculty success; 2) poor communication of policies impairs access and affects organizational climate; 3) discrepancies in leave implementation disadvantage certain faculty in terms of time and pay; and 4) leave policies are valued and directly related to academic productivity. Family leave policies are an important aspect of faculty satisfaction and academic success, yet policy awareness among senior leaders is lacking. Further organizational support is needed to promote equitable policy creation and implementation to support women in medical academia. Copyright © 2014 Jacobs Institute of Women's Health.

Long-term sickness absence is one of the main risk factors for permanent exit out of the labour market. Early identification of the condition is essential to facilitate return to work. The aim of this study was to analyse possible determinants of return to work and their relative impact. All 943 subjects aged 18 to 63 years, sickness certified at a Primary Health Care Centre in Sweden from 1 January until 31 August 2004, were followed up for three years. Baseline information on sex, age, sick leave diagnosis, employment status, extent of sick leave, and sickness absence during the year before baseline was obtained, as was information on all compensated days of sick leave, disability pension and death during follow-up. Slightly more than half the subjects were women, mean age was 39 years. Half of the study population returned to work within 14 days after baseline, and after three years only 15 subjects were still on sick leave. In multivariate proportional hazards regression analysis the extent of previous sick leave, age, being on part-time sick leave, and having a psychiatric, musculoskeletal, cardiovascular, nervous disease, digestive system, or injury or poisoning diagnosis decreased the return to work rate, while being employed increased it. Marital status, sex, being born in Sweden, citizenship, and annual salary had no influence. In logistic regression analyses across follow-up time these variables altogether explained 88-90% of return to work variation. Return to work was positively or negatively associated by a number of variables easily accessible in the GP's office. Track record data in the form of previous sick leave was the most influential variable.

Should laparoscopic cholecystectomy be practiced in the developing world?: the experience of the first training program in Afghanistan.

We address the controversial issue of whether or not it is wise to perform and train laparoscopic cholecystectomy (LC) in a developing nation by reviewing the results of the first large series done in Afghanistan. Afghanistan has been devastated by 3 decades of war leaving it with deficiencies in training programs, medical technologies, and overall medical infrastructure that are among the worst in the developing world. We retrospectively reviewed 137 consecutive cholecystectomies, 102 laparoscopic and 35 open, performed by 4 senior and 3 junior surgeons trained at our hospital in Kabul from July 2005 until February 2008. Deaths, complications, conversion rate, operative time, and hospital length of stay were compared. Unrecognized major operative injuries occurred in 4 LC patients, 3 bile leaks, and 1 duodenal perforation, although there were no such injuries in the open cholecystectomy group. Complication rates were much higher for patients operated on for acute cholecystitis for both surgeon groups. Even though junior surgeons converted to open cholecystectomy more frequently than senior surgeons, they had a higher major complication rate. Hospital length of stay was 28% shorter for the laparoscopic group. The high rate of major unrecognized intraoperative complications during LC in our series underscores the difficulties inherent in performing and training LC in developing nations. Practical changes are suggested to make LC more efficient and safer in a developing world hospital.

Evidence-based information on the resumption of daily activities following uncomplicated abdominal surgery is scarce and not yet standardized in medical guidelines. As a consequence, convalescence recommendations are generally not provided after surgery, leading to patients' insecurity, needlessly delayed recovery and prolonged sick leave. The aim of this study was to generate consensus-based multidisciplinary convalescence recommendations, including advice on return to work, applicable for both patients and physicians. Using a modified Delphi method among a multidisciplinary panel of 13 experts consisting of surgeons, occupational physicians and general practitioners, detailed recommendations were developed for graded resumption of 34 activities after uncomplicated laparoscopic cholecystectomy, laparoscopic and open appendectomy, laparoscopic and open colectomy and laparoscopic and open inguinal hernia repair. A sample of occupational physicians, general practitioners and surgeons assessed the recommendations on feasibility in daily practice. The response of this group of care providers was discussed with the experts in the final Delphi questionnaire round. Out of initially 56 activities, the expert panel selected 34 relevant activities for which convalescence recommendations were developed. After four Delphi rounds, consensus was reached for all of the 34 activities for all the surgical procedures. A sample of occupational physicians, general practitioners and surgeons regarded the recommendations as feasible in daily practice. Multidisciplinary convalescence recommendations regarding uncomplicated laparoscopic cholecystectomy, appendectomy (laparoscopic, open), colectomy (laparoscopic, open) and inguinal hernia repair (laparoscopic, open) were developed by a modified Delphi procedure. Further research is required to evaluate whether these recommendations are realistic and effective in daily practice.

Levels of pyridine alkaloids were measured in 18 tobacco, Nicotiana tabacum L., entries from three parental isolines ('NC 95', 'SC 58', and 'Coker 139'), grown at Tifton, GA, Florence, SC, and Oxford, NC, in 1991. Levels of alkaloids in bud leaves (first fully unfolded leaf below the apical leaf bud) were negatively correlated to natural infestation ratings of tobacco budworm larvae, Heliothis virescens (F.), 7 wk after transplanting. For artificially infested bud leaves at Oxford, there was a significant negative correlation between levels of total alkaloids and larval weights after 1 wk of feeding. In 1992, four entries from the 'NC 95' isoline were grown at Oxford, and samples for alkaloid analyses were taken every 2 wk at several leaf positions on each plant. During weeks 4, 8, 12, and 16, second instar tobacco budworms were caged on individual, intact leaves inside perforated plastic bags in the field. The survival and development of tobacco budworm larvae after 1 wk were negatively correlated with levels of alkaloids at the various leaf positions. Larvae survived better and grew faster on the bud leaves of each entry where alkaloid levels were lower than they did on leaves further down the stalk where alkaloid levels were higher. More larvae survived on the lower leaves of the low alkaloid lines than on the lower leaves of the high alkaloid lines. Even moderate increases in pyridine alkaloids had negative effects on tobacco budworm survival and development. Nicotine constituted >97% of the pyridine alkaloids in the 'NC95' isoline each year.

Final cook temperature monitoring

Fully cooked, ready-to-eat products represent one of the fastest growing markets in the meat and poultry industries. Modern meat cooking facilities typically cook chicken strips and nuggets at rates of 6000 lbs per hour, and it is a critical food safety issue to ensure the products on these lines are indeed fully cooked. Common practice now employs oven technicians to constantly measure final cook temperature with insertion-type thermocouple probes. Prior research has demonstrated that thermal imagery of chicken breasts and other products can be used to predict core temperature of products leaving an oven. In practice, implementation of a system to monitor core temperature can be difficult for several reasons. First, a wide variety of products are typically produced on the same production line and the system must adapt to all products. Second, the products can be often hard to find because they often leave the process in random order and may be touching or even overlapping. Another issue is finite measurement time which is typically only a few seconds. Finally, the system is subjected to a rigorous sanitation cycle and must hold up under wash down conditions. To address these problems, a calibrated 320x240 micro-bolometer camera was used to monitor the temperature of formed, breaded poultry products on a fully cooked production line for a period of one year. The study addressed the installation and operation of the system as well as the development of algorithms used to identify the product on a cluttered conveyor belt. It also compared the oven tech insertion probe measurements to the non-contact monitoring system performance.

Mindfulness and meditation as an adjunctive treatment for adolescents involved in the juvenile justice system: Is repairing the brain and nervous system possible?

Adolescents involved in the juvenile justice system are prone to more traumatic events than other adolescents, leaving them in danger of developmental difficulties. Trauma exposure is predictive of poor outcomes including mental and physical health issues as well as criminal activity. Current treatment approaches either have a nominal effect on recidivism rates or increase the likelihood of future criminal offenses. This article explores adolescent brain development, the unique difficulties that juvenile justice youth face, and mindfulness meditation as an adjunctive treatment to system-based treatment. Mindfulness meditation may be a way to redress damage to the brain and facilitate healthy brain development, thus impacting prosocial behavior. Practice implications include integrating mindfulness meditation as an important part of rehabilitative efforts with juvenile justice youth.

To assess relationships between primary care work conditions, physician burnout, quality of care, and medical errors. Cross-sectional and longitudinal analyses of data from the MEMO (Minimizing Error, Maximizing Outcome) Study. Two surveys of 422 family physicians and general internists, administered 1 year apart, queried physician job satisfaction, stress and burnout, organizational culture, and intent to leave within 2 years. A chart audit of 1795 of their adult patients with diabetes and/or hypertension assessed care quality and medical errors. Women physicians were almost twice as likely as men to report burnout (36% vs 19%, P < .001). Burned out clinicians reported less satisfaction (P < .001), more job stress (P < .001), more time pressure during visits (P < .01), more chaotic work conditions (P < .001), and less work control (P < .001). Their workplaces were less likely to emphasize work-life balance (P < .001) and they noted more intent to leave the practice (56% vs 21%, P < .001). There were no consistent relationships between burnout, care quality, and medical errors. Burnout is highly associated with adverse work conditions and a greater intention to leave the practice, but not with adverse patient outcomes. Care quality thus appears to be preserved at great personal cost to primary care physicians. Efforts focused on workplace redesign and physician self-care are warranted to sustain the primary care workforce. © The Author(s) 2015.

The objective of this study was to highlight and assess the important topic of the voluntary departure of the physician from his/her clinic. We used the topic of the voluntary departure of a family physician from the clinic as an example. The physician's leaving challenges the personal credo regarding the continuity of care, which is a basic concept in Family Medicine, and other professions, too: Psychiatrists are also devoted to long-term doctor-patient care. Leaving a place of work is a significant life event that can be accompanied by stress and even a crisis for the doctor, patients, and staff. In this article, we will present four stories, of four family physicians who voluntarily left their practices, written from a reflective point of view, either before or after the actual departure. The stories will be analyzed in a qualitative way, and the central themes and narratives will be defined. The personal departure stories revealed important personal and systemic themes that emerge from and influence the departure process. Among the themes were: practical and emotional work circumstances; leaving as a grief process; and reactions of patients, staff, and management. Qualitative analysis revealed that the voluntary departure of the family physician has complex personal and systemic implications. The combination of Balint group discussions and written reflections can help the physician better cope with the departure and also help patients and staff deal with the separation process.

Abundant literature has been devoted to coffee beans (green or roasted) chemical description but relatively few studies have been devoted to coffee leaves. Given the fact that coffee leaves are used for food and medicinal consumption, it was of interest to develop a rapid screening method in order to identify coffee leaves taxa. Investigation by Fourier - Transform near infrared spectroscopy (FT-NIRS) was performed on nine Coffea taxa leaves harvested over one year in a tropical greenhouse of the Botanic Garden Meise (Belgium). The only process after leaves harvesting was an effective drying and a homogeneous leaves grinding. FT-NIRS with SIMCA analysis allowed to discriminate the spectral profiles across taxon, aging stage (mature and senescence coffee leaves) and harvest period. This study showed that it was possible (i) to classify the different taxa, (ii) to identify their aging stage and (iii) to identify the harvest period for the mature stage with a correct classification rate of 99%, 100% and 90%, respectively.

Young maize plants were inoculated on unfolded mature leaves and on folded immature leaves with Fusarium graminearum, Fusarium proliferatum, and Fusarium verticillioides suspensions. Infection and symptom development of disease on these asymptomatic mature leaves and immature leaves were then documented. Subcuticular infection was found by the three Fusarium species on both symptomatic and symptomless leaves. The three Fusarium species penetrated the stomata of immature leaves by the formation of appressoria-like structures, infection cushions or by direct penetration. Infection by the three species of Fusarium via stomata is reported here for the first time. The superficial hyphae and re-emerging hyphae of the three species produced conidia. The macroconidia of F. graminearum produced secondary macroconidia and F. proliferatum formed microconidia inside the leaf tissues that sporulated through stomata and trichomes. The infection of maize leaves by the three species of Fusarium and their sporulation may contribute inoculum to cob and kernel infection. Copyright © 2016 British Mycological Society.

Pepper (Capsicum annuum L.) is an economically important agricultural crop and an excellent dietary source of natural colors and antioxidant compounds. The levels of these compounds can vary according to agricultural practices, like inoculation with plant growth-promoting rhizobacteria. In this work we evaluated for the first time the effect of the inoculation of two Rhizobium strains on C. annuum metabolites and bioactivity. The results revealed a decrease of organic acids and no effect on phenolics and capsaicinoids of leaves from inoculated plants. In the fruits from inoculated plants organic acids and phenolic compounds decreased, showing that fruits from inoculated plants present a higher ripeness stage than those from uninoculated ones. In general, the inoculation with Rhizobium did not improve the antioxidant activity of pepper fruits and leaves. Considering the positive effect on fruit ripening, the inoculation of C. annuum with Rhizobium is a beneficious agricultural practice for this nonlegume.

Flexible kinship: caring for AIDS orphans in rural Lesotho

HIV/AIDS has devastated families in rural Lesotho, leaving many children orphaned. Families have adapted to the increase in the number of orphans and HIV-positive children in ways that provide children with the best possible care. Though local ideas about kinship and care are firmly rooted in patrilineal social organization, in practice, maternal caregivers, often grandmothers, are increasingly caring for orphaned children. Negotiations between affinal kin capitalize on flexible kinship practices in order to legitimate new patterns of care, which have shifted towards a model that often favours matrilocal practices of care in the context of idealized patrilineality.

Cannabis is used in an orally administered form called bhang which can be either the wet resinous leaves formed into pills of a drink made of milk, cannabis, and various spices consumed by worshipers of Shiva on festival days or by smoking the flowering buds of cannabis-a practice generally reserved for holy men who dedicate their lives to ascetic practice and the worship of Shiva. This practice is codified in the Vedas as well as in legends about the origin of cannabis and its relationship to Shiva.

Role of Pea Enation Mosaic Virus Coat Protein in the Host Plant and Aphid Vector.

2016-11-18

Understanding the molecular mechanisms involved in plant virus-vector interactions is essential for the development of effective control measures for aphid-vectored epidemic plant diseases. The coat proteins (CP) are the main component of the viral capsids, and they are implicated in practically every stage of the viral infection cycle. Pea enation mosaic virus 1 (PEMV1, Enamovirus , Luteoviridae ) and Pea enation mosaic virus 2 (PEMV2, Umbravirus , Tombusviridae ) are two RNA viruses in an obligate symbiosis causing the pea enation mosaic disease. Sixteen mutant viruses were generated with mutations in different domains of the CP to evaluate the role of specific amino acids in viral replication, virion assembly, long-distance movement in Pisum sativum , and aphid transmission. Twelve mutant viruses were unable to assemble but were able to replicate in inoculated leaves, move long-distance, and express the CP in newly infected leaves. Four mutant viruses produced virions, but three were not transmissible by the pea aphid, Acyrthosiphon pisum . Three-dimensional modeling of the PEMV CP, combined with biological assays for virion assembly and aphid transmission, allowed for a model of the assembly of PEMV coat protein subunits.

Pediatric medicine often struggles to receive adequate research funding for its small, yet vulnerable population of patients. Remarkable discovery in pediatric oncology is credited in large part to the collaborative structure of its research community. The Children's Oncology Group conducts studies supported by the National Cancer Institute. The clinical research associate (CRA) discipline comprises professionals who support administrative duties, regulatory duties, subject management, and data collection at individual research sites. The purpose of this study was to identify factors associated with CRA retention, as the group continues to have high turnover and position vacancy. A cross-sectional survey design was used to characterize the most frequently cited reasons CRAs gave when considering leaving or staying within their position. Results suggest that low salary, unmanageable workload, lack of career advancement and professional development, and lack of research commitment from the medical team were associated with intent to leave CRA positions. The most frequently cited reasons for staying at their job were the meaningfulness and interest in the work, a supportive principal investigator, and enjoyment working with colleagues. CRAs reported serious but eminently solvable issues that can be addressed using practical and low-cost solutions to improve job satisfaction and retention.

Otto Deiters, for whom the lateral vestibular nucleus and the supporting cells of the outer auditory hair cells were named, died in 1863 aged 29. He taught in the Bonn Anatomy Department, had an appointment in the University Clinic, and ran a small private practice. He published articles on the cell theory, the structure and development of muscle fibers, the inner ear, leukaemia, and scarlet fever. He was the second of five surviving children in an academic family whose private correspondence revealed him to be a young man with limited social skills and high ambitions to complete a deeply original study of the brainstem and spinal cord. However, first his father and then his younger brother died, leaving him and his older brother responsible for a suddenly impecunious family as he failed to gain academic promotion. Otto died of typhus two years after his younger brother's death, leaving his greatest scientific achievement to be published posthumously. He showed that most nerve cells have a single axon and several dendrites; he recognized the possibility that nerve cells might be functionally polarized and produced the first illustrations of synaptic inputs to dendrites from what he termed a second system of nerve fibers.

Partner relationships and long-term sick leave among female workers: consequences and impact on dimensions of health and return to work.

PubMed

Dellve, Lotta; Ahlborg, Tone

2012-12-01

Few efforts have been made to prospectively identify resources and obstacles outside work that may predict regained work ability and return to work when workers are on sick leave. This study investigates the association between partner relationships and sick leave. Our research questions were as follows: (i) What is the influence of sick leave, pain, stress and domestic strain on the quality of the dyadic partner relationship?, and (ii) What is the influence of the partner and social relationship on pain, stress, work ability, self-rated health and return to work? A cohort of female workers (n = 225) on long-term sick leave (>60 days), all in a partner relationship, at 6-month intervals completed a questionnaire based on the Quality of Dyadic Relationship (QDR) instrument, the Interview Schedule of Social Interaction (ISSI), the Work Ability Index (WAI) and the Copenhagen Psychosocial Questionnaire (COPSOQ). Univariate and multivariate analyses of baseline and prospective data were performed. The results showed that decreased partner relationship quality was related to having major responsibility for household work despite being on sick leave, having pain and having decreased social integration. Among younger individuals on sick leave, a reduction in the quality of the partner relationship was shown already at the first (6-month) follow-up, while among middle-aged women, such a reduction was seen only at the 12-month follow-up. No dimensions of partner relationship quality at baseline were related to dimensions of return to work, either as a resource or as an obstacle. Consequently, our results show that a good relationship does not keep the woman from returning to work. Having main responsibility for household work, which implies domestic strain while on sick leave, predicts lower partner relationship quality. The practical implications are that healthcare professionals treating women on sick leave should emphasize the importance of keeping a social network as well as making sufficient adjustments at home for the relationship quality to be safeguarded. Special attention should be given to the young woman on sick leave as being on sick leave seems to influence her partner relationship considerably. © 2012 The Authors.

Joining a discourse community: How graduate students learn to speak like astronomers

NASA Astrophysics Data System (ADS)

Baleisis, Audra

Almost half of all graduate students leave their doctoral programs without finishing. Who leaves, taking which skills and strengths with them, is still poorly understood, however, because it is hard to measure exactly what graduate students learn in their doctoral programs. Since the expertise required of a PhD holder is highly dependent on discipline, the development of a better understanding of graduate education and attrition requires studying the process at the departmental level. This is a qualitative study of the cultural values and norms of academic astronomy, as transmitted through the socialization of graduate students in to giving talks, asking questions, and participating in departmental speaking events. This study also looks at the conflicts that arise when implicit cultural norms, which are practiced but remain unacknowledged, are inconsistent with the official, explicit values and norms for speaking in astronomy. Doctoral students and faculty members in a single astronomy department, at a large western university, filled out a short survey about the stakes involved in astronomy speaking events. A subset of these individuals was interviewed in- depth about the goals of, and their experiences with, five departmental speaking events: Coffee Hour, Journal Club, research talks, Thesis defense talks, and Colloquia. These interviewees were: (1) graduate students who had given a verbal presentation at one of these events, and (2) graduate students and faculty members who were in the audience at a graduate student's presentation. The desired outcomes which were expressed for these speaking events included: (1) lively, informal discussion among all participants, (2) increasing graduate student verbal participation in these events as they "learn to speak like astronomers," and (3) the utility of these events in helping graduate students learn and practice their speaking and reasoning skills related to astronomy research. In practice these goals were not achieved due to: (1) the ubiquitous, but unacknowledged practice of judging others' speech performance to come to negative conclusions about those individuals' intentions, intellectual abilities or efforts, (2) a lack of feedback for graduate students on their verbal performances, and (3) a lack of faculty members making explicit their own solutions to the inherent dilemmas of academic speaking.

Factors modulating cottongrass seedling growth stimulation to enhanced nitrogen and carbon dioxide: compensatory tradeoffs in leaf dynamics and allocation to meet potassium-limited growth.

Eriophorum vaginatum is a characteristic species of northern peatlands and a keystone plant for cutover bog restoration. Understanding the factors affecting E. vaginatum seedling establishment (i.e. growth dynamics and allocation) under global change has practical implications for the management of abandoned mined bogs and restoration of their C-sequestration function. We studied the responses of leaf dynamics, above- and belowground biomass production of establishing seedlings to elevated CO(2) and N. We hypothesised that nutrient factors such as limitation shifts or dilutions would modulate growth stimulation. Elevated CO(2) did not affect biomass, but increased the number of young leaves in spring (+400 %), and the plant vitality (i.e. number of green leaves/total number of leaves) (+3 %), both of which were negatively correlated to [K(+)] in surface porewater, suggesting a K-limited production of young leaves. Nutrient ratios in green leaves indicated either N and K co-limitation or K limitation. N addition enhanced the number of tillers (+38 %), green leaves (+18 %), aboveground and belowground biomass (+99, +61 %), leaf mass-to-length ratio (+28 %), and reduced the leaf turnover (-32 %). N addition enhanced N availability and decreased [K(+)] in spring surface porewater. Increased tiller and leaf production in July were associated with a doubling in [K(+)] in surface porewater suggesting that under enhanced N production is K driven. Both experiments illustrate the importance of tradeoffs in E. vaginatum growth between: (1) producing tillers and generating new leaves, (2) maintaining adult leaves and initiating new ones, and (3) investing in basal parts (corms) for storage or in root growth for greater K uptake. The K concentration in surface porewater is thus the single most important factor controlling the growth of E. vaginatum seedlings in the regeneration of selected cutover bogs.

A Global Regulation Inducing the Shape of Growing Folded Leaves

PubMed Central

Couturier, Etienne; Courrech du Pont, Sylvain; Douady, Stéphane

2009-01-01

Shape is one of the important characteristics for the structures observed in living organisms. Whereas biologists have proposed models where the shape is controlled on a molecular level [1], physicists, following Turing [2] and d'Arcy Thomson [3], have developed theories where patterns arise spontaneously [4]. Here, we propose that volume constraints restrict the possible shapes of leaves. Focusing on palmate leaves (with lobes), the central observation is that developing leaves first grow folded inside a bud, limited by the previous and subsequent leaves. We show that the lobe perimeters end at the border of this small volume. This induces a direct relationship between the way it was folded and the final unfolded shape of the leaf. These dependencies can be approximated as simple geometrical relationships that we confirm on both folded embryonic and unfolded mature leaves. We find that independent of their position in the phylogenetic tree, these relationships work for folded species, but do not work for non-folded species. This global regulation for the leaf growth could come from a mechanical steric constraint. Such steric regulation should be more general and considered as a new simple means of global regulation.

Recently, the so-called “plant factory with artificial lighting” (PFAL) approach has been developed to provide safe and steady food production. Although PFALs can produce high-yielding and high-quality plants, the high plant density in these systems accelerates leaf senescence in the bottom (or outer) leaves owing to shading by the upper (or inner) leaves and by neighboring plants. This decreases yield and increases labor costs for trimming. Thus, the establishment of cultivation methods to retard senescence of outer leaves is an important research goal to improve PFAL yield and profitability. In the present study, we developed an LED lighting apparatus that would optimize light conditions for PFAL cultivation of a leafy vegetable. Lettuce (Lactuca sativa L.) was hydroponically grown under white, red, or blue LEDs, with light provided from above (downward), with or without supplemental upward lighting from underneath the plant. White LEDs proved more appropriate for lettuce growth than red or blue LEDs, and the supplemental lighting retarded the senescence of outer leaves and decreased waste (i.e., dead or low-quality senescent leaves), leading to an improvement of the marketable leaf fresh weight.

A sensitive gas chromatographic (GC) GC method has been developed for the determination of diazinon and chlorpyrifos residues in lavender and rosemary leaves. The developed method consists of blending weighed samples of chopped leaves with sodium sulfate as the dehydrating agent, extraction with ethyl acetate, filtration, evaporation with a rotary evaporator, and, finally, capillary GC determination of the pesticides. The recoveries of the method were greater than 90%, and the LOQ was less than 0.1 µg/mL. The method was applied to determine the rate of disappearance of diazinon and chlorpyrifos from lavender and rosemary leaves pretreated with the studied pesticides. The half-life values (t1/2) of diazinon were found to be 5.93 and 6.35 days for lavender and rosemary leaves, respectively, whereas the t1/2 values of chlorpyrifos were calculated to be 7.86 and 9.52 days for lavender and rosemary leaves, respectively. The safe harvest interval (preharvest interval; PHI) was suggested to be after 21 and 24 days for diazinon and chlorpyrifos, respectively. The PHI refers to the amount of time that must lapse (in days) after a pesticide application before a crop can be cut.

Oak (Quercus) seedlings exhibit a pattern of shoot growth known to place demands on carbohydrate and nutrient reserves. This study was designed to determine ontogenetic patterns in CO{sub 2} exchanges properties of red oak leaves, and to determine if individual leaf CO{sub 2} exchange rates (CER) increase in response to the assimilate demand placed on a seedling during flushing. Northern red oak (Q. rubra L.) seedlings were grown in environments favorable for multiple flushes of shoot growth. Measurements of CER on single, attached, median leaves from each flush were made over a range of photosynthetic photon flux densities on plantsmore » at nine stages of seedling development through three flushes of growth. Carbon dioxide exchange rate of red oak leaves increased during leaf development up to and beyond full leaf expansion before decreasing an unusual pattern of photosynthesis during leaf ontogeny. Furthermore, first- and second-flush leaf CER initially decreased and then increased in conjunction with the third flush of shoot growth. These patterns indicate that red oak leaves have a capacity for CER adjustment in response to increase sink demand.« less

Interest in the well-being of physicians has increased because of their contributions to the healthcare system quality. There is growing recognition that physicians are exposed to workplace factors that increase the risk of work stress. Long-term exposure to high work stress can result in burnout. Reports from around the world suggest that about one-third to one-half of physicians experience burnout. Understanding the outcomes associated with burnout is critical to understanding its affects on the healthcare system. Productivity outcomes are among those that could have the most immediate effects on the healthcare system. This systematic literature review is one of the first to explore the evidence for the types of physician productivity outcomes associated with physician burnout. It answers the question, "How does burnout affect physician productivity?" A systematic search was performed of: Medline Current, Medline in process, PsycInfo, Embase and Web of Science. The search period covered 2002 to 2012. The searches identified articles about practicing physicians working in civilian settings. Articles that primarily looked only at residents or medical students were excluded. Productivity was captured by hours worked, patients seen, sick leave, leaving the profession, retirement, workload and presenteeism. Studies also were excluded if: (1) the study sample was not comprised of at least 50% physicians, (2) the study did not examine the relationship between burnout and productivity or (3) a validated measure of burnout was not used. The search identified 870 unique citations; 5 met the inclusion/exclusion criteria. This review indicates that globally there is recognition of the potential impact of physician burnout on productivity. Productivity was examined using: number of sick leave days, work ability, intent to either continue practicing or change jobs. The majority of the studies indicate there is a negative relationship between burnout and productivity. However, there is variation depending on the type of productivity outcome examined. There is evidence that burnout is associated with decreased productivity. However, this line of inquiry is still developing. A number of gaps are yet to be filled including understanding how to quantify the changes in productivity related to burnout.

Exploring the Relationship between Beginning Science Teachers' Practices, Institutional Constraints, and Adult Development

NASA Astrophysics Data System (ADS)

Wilcox, Jesse Lee

This year-long study explored how ten teachers--five first year, five second year--acclimated to their new school environment after leaving a master's level university science teacher preparation program known for being highly effective. Furthermore, this study sought to explore if a relationship existed between teachers' understanding and implementation of research-based science teaching practices, the barriers to enacting these practices--known as institutional constraints, and the constructive-developmental theory which explores meaning-making systems known as orders of consciousness. As a naturalistic inquiry mixed methods study, data were collected using both qualitative (e.g., semi-structured interviews, field notes) as well as quantitative methods (e.g., observation protocols, subject/object protocol). These data sources were used to construct participant summaries and a cross-case analysis. The findings from provide evidence that teachers' orders of consciousness might help to explain why understanding research-based science teaching practices are maintained by some new teachers and not others. Additionally, this study found the orders of consciousness of teachers relates to the perceptions of institutional constraints as well as how a teacher chooses to navigate those constraints. Finally, the extent to which teachers implement research-based science teaching practices is related to orders of consciousness. While many studies have focused on what meaning teachers make, this study highlights the importance of considering how teachers make meaning.

Postgraduate medical training is undergoing major change, shortening and disrupting traditional practices. Scholarship remains highly valued, but increasingly difficult to fit in. Workplace-based Masters study offers a solution. We want consultants who are driven by enquiry, good teachers and team workers. Academic qualifications demonstrate trainees' commitment and expertise in competitive employment markets. Most Deaneries allow two sessions weekly for research/personal development, so this resource demands effective use. The good will, talent and commitment of colleagues are vital. A credible structured curriculum combines real-life consultant-level generic practice, with technical medical skills. Academic writing and practical assignments are assessed. Linking with a far-sighted academic institution brings vast expertise in education administration and delivery of accredited learning. The course is more cost-effective than traditional study leave activities. Running part-time over 4 years fits with Higher Specialist Training. Structured programmes, over 9 month 'terms', fit with clinical rotations. Module leaders run yearly clinical modules alongside continuous generic modules. Clinical units are signed up to releasing trainees to attend. Evaluation is external to faculty, with highly favourable feedback. We believe training in academic disciplines underpins practice. With strong partnership working, planning and especially hard work, such a course is deliverable.

Continuing medical education serves a central role in the licensure and certification for practicing physicians. This chapter explores the different modalities that constitute CME along with their effectiveness, including simulation and best education practices. The evolution to maintenance of certification and the requirements for both the American Board of Surgery and the American Board of Colon and Rectal Surgery are delineated. Further progress in the education of practicing surgeons is evidenced through the introduction of laparoscopic colectomy and the improvements made from the introduction of laparoscopic cholecystectomy. Finally, reentry of physicians into practice following a voluntary leave of absence, a new and challenging issue for surgeons, is also discussed. PMID:23997673

The effects of burnout and supervisory social support on the relationship between work-family conflict and intention to leave: a study of Australian cancer workers.

2009-01-01

The aim of this paper is to examine the effects of burnout and supervisory social support on the relationship between work-family conflict, and intention to leave of cancer workers in an Australian health care setting. Data collected from a public hospital of 114 cancer workers were used to test a model of the consequences of work-family conflict. The strength of the indirect effects of work-family conflict on intention to leave via burnout will depend on supervisor support was tested by conducting a moderated mediation analysis. Path analytic tests of moderated mediation supported the hypothesis that burnout mediates the relationship between work-family conflict (i.e., work-in-family conflict and family-in-work) and intention to leave the organisation and that the mediation framework is stronger in the presence of higher social supervisory support. Implications are drawn for theory, research and practice. This study applies the innovative statistical technique of moderated mediation analysis to demonstrate that burnout mediates the relationship between work-family conflict and intention to leave the organisation and that the mediation framework is stronger in the presence of lower social supervisory support. In the context of the continued shortage of many clinician groups theses results shed further light on the appropriate course of action for hospital management.

Canopy storage capacity and wettability of leaves and needles: The effect of water temperature changes

NASA Astrophysics Data System (ADS)

Klamerus-Iwan, Anna; Błońska, Ewa

2018-04-01

The canopy storage capacity (S) is a major component of the surface water balance. We analysed the relationship between the tree canopy water storage capacity and leaf wettability under changing simulated rainfall temperature. We estimated the effect of the rain temperature change on the canopy storage capacity and contact angle of leave and needle surfaces based on two scenarios. Six dominant forest trees were analysed: English oak (Quercus roburL.), common beech (Fagus sylvatica L.), small-leaved lime (Tilia cordata Mill), silver fir (Abies alba), Scots pine (Pinus sylvestris L.),and Norway spruce (Picea abies L.). Twigs of these species were collected from Krynica Zdrój, that is, the Experimental Forestry unit of the University of Agriculture in Cracow (southern Poland). Experimental analyses (simulations of precipitation) were performed in a laboratory under controlled conditions. The canopy storage capacity and leaf wettability classification were determined at 12 water temperatures and a practical calculator to compute changes of S and contact angles of droplets was developed. Among all species, an increase of the rainfall temperature by 0.7 °C decreases the contact angle between leave and needle surfaces by 2.41° and increases the canopy storage capacity by 0.74 g g-1; an increase of the rain temperature by 2.7 °C decreases the contact angle by 9.29° and increases the canopy storage capacity by 2.85 g g-1. A decreased contact angle between a water droplet and leaf surface indicates increased wettability. Thus, our results show that an increased temperature increases the leaf wettability in all examined species. The comparison of different species implies that the water temperature has the strongest effect on spruce and the weakest effect on oak. These data indicate that the rainfall temperature influences the canopy storage capacity.

Effects of self-recording on attendance and performance in a competitive swimming training environment

Swimmers' attendance at training and work rates were described by their coaches as being poor and irregular. Reinforcement contingencies were developed to remedy these unsatisfactory conditions. Two experiments were conducted. A multiple baseline design verified the effects of publicly marking attendance at practice as a sufficient solution for reducing absenteeism, tardiness, and leaving early. Follow-up analyses showed this contingency to have lasting effects. In the second experiment, a reversal design was used to assess the effects of employing program boards as a means of increasing work output during practice. Work rates in eight selected swimmers were elevated by an average of 27.1% when the boards were instituted. Follow-up evaluations showed that the use of the program boards had lasting effects. Publicly checking the completion of each training unit of work changed the nature of the swimming environment to produce a more productive use of time. The role of the coach was subsequently changed as less time was spent in directing and supervising behaviors. PMID:4436167

Air Emissions and Health Benefits from Using Sugarcane Waste as a Cellulosic Ethanol Feedstock

Brazil, as the largest ethanol exporter in the world, faces rapid expansion of ethanol production due to the increase of global biofuels demand. Current production of Brazilian sugarcane ethanol causes significant air emissions mainly from the open burning phase of agriculture wastes (i.e. sugarcane straws and leaves) resulting in potential health impacts. One possible measure to avoid undesired burning practices is to increase the utilization of unburned sugarcane residues as a feedstock for cellulosic ethanol. To explore the benefits of this substitution, here we first apply a bottom-up approach combining agronomic data and life-cycle models to investigate spatially and temporally explicit emissions from sugarcane waste burning. We further quantify the health benefits from preventing burning practices using the CMAQ regional air quality model and the BenMAP health benefit analysis tool adapted for Brazilian applications. Furthermore, the health impacts will be converted into monetary values which provide policymakers useful information for the development of cellulosic ethanol.

Acquisition and diversification of tendrilled leaves in Bignonieae (Bignoniaceae) involved changes in expression patterns of SHOOTMERISTEMLESS (STM), LEAFY/FLORICAULA (LFY/FLO), and PHANTASTICA (PHAN).

Leaves have undergone structural modifications over evolutionary time, and presently exist in many forms. For instance, in Fabaceae and Bignoniaceae, leaf parts can be modified into tendrils. Currently, no data are available on genic control of tendrilled leaf development outside Fabaceae. Here, we conducted a detailed study of three representatives of Bignonieae: Amphilophium buccinatorium, Dolichandra unguis-cati, and Bignonia callistegioides, bearing multifid, trifid, and simple-tendrilled leaves, respectively. We investigated the structure of their petioles, petiolules, leaflets, and tendrils through histological analyses. Additionally, the expression of SHOOTMERISTEMLESS (STM), PHANTASTICA (PHAN), and LEAFY/FLORICAULA (LFY/FLO) during leaf development was analyzed by in situ hybridizations. Tendrils share some anatomical similarities with leaflets, but not with other leaf parts. Transcripts of both STM and LFY/FLO were detected in leaf primordia, associated with regions from which leaflets and tendril branches originate. PHAN expression was found to be polarized in branched tendrils, but not in simple tendrils. In Bignonieae, tendrils are modified leaflets that, as a result of premature completion of development, become bladeless organs. Bignonieae leaves develop differently from those of peas, as both LFY/FLO and STM are expressed in developing leaves of Bignonieae. Moreover, PHAN is probably involved in tendril diversification in Bignonieae, as it has distinct expression patterns in different leaf types. © 2013 The Authors.

Rethinking work and family policy: the making and taking of parental leave in Australia.

PubMed

Baird, M; Litwin, A S

2005-10-01

Despite the continued increase in female participation rates, Australia remains one of only two developed nations in the world without a paid maternity leave scheme. While research interest and public policy debate about paid maternity leave entitlements continues, little is known about the actual utilization of the 52 weeks unpaid parental leave that is currently available to all employees. Moreover, research and policy debate on the availability and provision of paid paternity leave has only just begun. This paper argues that, given the gendered nature of employee entitlements, it is time to re-evaluate all aspects of parental leave policy in Australia. Using unique data from a national survey of Australian employees, the paper provides a statistical analysis of the use of unpaid parental leave and the availability of paid maternity leave. The paper models the availability of paid maternity leave to Australian employees as a function of demographic and organizational characteristics, including annual income, union status, and establishment size. A parallel analysis of the likelihood that an individual has used the unpaid parental leave provision is also provided. The results show that the existing unpaid parental leave provision is rarely used and that the current availability of paid maternity leave is inequitable. The paper discusses the conceptual and policy implications of these results and concludes that a re-thinking of parental leave policy in Australia is essential if gender inequities at work and in society are to be addressed.

Tissue physiological metabolic adaptability in young and old leaves of reed (Phragmites communis) in Songnen grassland.

Common reed (Phragmites communis) is widely distributed as the dominant plant species in the Songnen Plain of China. The aim of this study was to investigate different physiological adaptive mechanisms to salinity tolerance between young and old leaves. The profiles of 68 metabolites were measured and studied in reed leaves by gas chromatography-mass spectrometer. The nitrogen, carbon, and pigment contents showed stronger growth inhibition for older leaves with salinity stress. In young leaves, high K + contents not only promoted cell growth, but also prevented influx of superfluous Na + ions in cells; the Ca 2+ accumulation in old leaves implied that Ca 2+ triggered the SOS-Na + exclusion system and reduced Na + toxicity. Thus, the mechanism of enhanced tolerance differed between young and old leaves. The metabolite results indicated that the young and old leaves had different mechanisms of osmotic regulation; sugars/polyols and amino acids played important roles in developing salinity tolerance in young leaves but high contents of fatty acids were important for old leaves. These results implied dramatically enhanced sugars and amino acid synthesis but inhibited energy metabolism in young leaves. In contrast, fatty acid synthesis was enhanced in old leaves. The results extended our understanding of the differences in physiological metabolism in adaptive to the salt-alkalization of soil in Songnen grassland between young and old leaves of reeds.

Specific roles of cyclic electron flow around photosystem I in photosynthetic regulation in immature and mature leaves.

2017-02-01

Cyclic electron flow (CEF) around photosystem I (PSI) is essential for photosynthesis in mature leaves. However, the physiological roles of CEF in immature leaves are little known. Here, we measured the PSI and PSII activities, light response changes in PSI and PSII energy quenching for immature and mature leaves of Erythrophleum guineense grown under full sunlight. Comparing with the maximum quantum yield of PSII (F v /F m ), the immature leaves had much lower values of the maximum photo-oxidizable P700 (P m ) than the mature leaves, suggesting the unsynchronized development of PSI and PSII activities. Furthermore, the immature leaves displayed significantly lower capacities for the photosynthetic electron flow through PSII (ETRII) and CEF. However, when exposed to high light, the immature leaves displayed higher levels of non-photochemical quenching (NPQ) and P700 oxidation ration [Y(ND)] than mature leaves. Under high light, the similar NPQ values were accompanied with much lower CEF activity in the immature leaves. These results suggest that, in immature leaves, CEF primarily contributes to photoprotection for PSI and PSII via acidification of thylakoid lumen. By comparison, in mature leaves, a large fraction of CEF-dependent generation of ΔpH contributes to ATP synthesis and a relative small proportion favors photoprotection via lumen acidification. These findings highlight the specific roles of CEF in photosynthetic regulation in immature and mature leaves. Copyright © 2016 Elsevier GmbH. All rights reserved.

A new model was iteratively developed and presents cancer comparative effectiveness research and important measures in a patient-centered, longitudinal chronic care model better reflecting contemporary cancer care in the context of the cancer care continuum, rather than a single-episode, acute-care perspective. Immediately relevant for federally funded comparative effectiveness research programs, the model informs an evolving framework articulating cancer comparative effectiveness research data needs, including evolutionary enhancements to registries and epidemiologic research data systems. We discuss elements of contemporary clinical practice, methodology improvements, and related needs affecting comparative effectiveness research's ability to yield findings clinicians, policy makers, and stakeholders can confidently act on.

Evaluating the effect of domestic cooking on the health benefits of vegetables has great practical importance. However, only a limited number of reports provide information on the effect of these treatments on the antioxidant capacity, polyphenol and S-alk(en)yl-L-cysteine sulfoxide (ACSO, e.g. isoalliin and methiin) content of the white shaft and green leaves of leek (Allium ampeloprasum var. porrum). In the present study, the antioxidant capacity of leek was highly influenced by cooking (blanching, boiling and steaming). Boiling had a negative effect on total phenolic content in the white shaft and green leaves. An obvious increase could be observed in the antioxidant capacity of the steamed green leaves, while steaming did not influence the polyphenolic content. Remarkably, blanching resulted in a slight increase in the ACSO content. Subjecting leek samples to a longer thermal treatment appeared to have a negative influence on the ACSO content in leek. Steaming was also responsible for a decrease in ACSOs. Methiin was less susceptible to heat treatment than isoalliin. In general, steaming appeared to be responsible for better retention of the bioactive compounds present in leek compared with boiling. © 2013 Society of Chemical Industry.

Agricultural irrigation water contains a variety of contaminants that can be introduced into the food chain through intake by irrigated crops. This paper describes an experiment under controlled conditions designed to simulate sprinkle irrigation with polluted water at two different relative humidities (40 and 90%). Specifically, shed lettuce-heart leaves were spiked with an aqueous solution containing organic microcontaminants, including pharmaceuticals (ibuprofen, diclofenac, clofibric acid, and carbamazepine), fragrances (tonalide), biocides (triclosan), insecticides (lindane), herbicides (atrazine), phenolic estrogen (bisphenol A), and polycyclic aromatic hydrocarbons (phenanthrene and pyrene). Following an incubation period (48 h), the treated leaves were rinsed with water, and both the solution used to rinse them and the leaves themselves were independently analyzed to investigate the foliar sorption and uptake of the spiked organic contaminants through cuticle. The results showed that the foliar sorption of emerging and priority microcontaminants in leaves wetted by irrigation practices is related to their polarity (logD(ow)) and volatility (logk(H)), regardless of their compound class and the relative humidity. The results thus underscore the need to improve the quality of reclaimed water in crop irrigation, particularly when sprinkle irrigation is used. Copyright © 2013 Elsevier B.V. All rights reserved.

Maternity Leave Policies

2017-01-01

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.

Leaf color change of variegated leaves from chimera species is regulated by fine-tuned molecular mechanisms. Hosta “Gold Standard” is a typical chimera Hosta species with golden-green variegated leaves, which is an ideal material to investigate the molecular mechanisms of leaf variegation. In this study, the margin and center regions of young and mature leaves from Hosta “Gold Standard”, as well as the leaves from plants after excess nitrogen fertilization were studied using physiological and comparative proteomic approaches. We identified 31 differentially expressed proteins in various regions and development stages of variegated leaves. Some of them may be related to the leaf color regulation in Hosta “Gold Standard”. For example, cytosolic glutamine synthetase (GS1), heat shock protein 70 (Hsp70), and chloroplastic elongation factor G (cpEF-G) were involved in pigment-related nitrogen synthesis as well as protein synthesis and processing. By integrating the proteomics data with physiological results, we revealed the metabolic patterns of nitrogen metabolism, photosynthesis, energy supply, as well as chloroplast protein synthesis, import and processing in various leaf regions at different development stages. Additionally, chloroplast-localized proteoforms involved in nitrogen metabolism, photosynthesis and protein processing implied that post-translational modifications were crucial for leaf color regulation. These results provide new clues toward understanding the mechanisms of leaf color regulation in variegated leaves. PMID:27005614

Ultra-fast liquid chromatography coupled with electrospray ionization time-of-flight mass spectrometry for the rapid phenolic profiling of red maple (Acer rubrum) leaves.

The red maple (Acer rubrum) species is economically important to North America because of its sap, which is used to produce maple syrup. In addition, various other red maple plant parts, including leaves, were used as a traditional medicine by the Native Americans. Currently, red maple leaves are being used for nutraceutical and cosmetic applications but there are no published analytical methods for comprehensive phytochemical characterization of this material. Herein, a rapid and sensitive method using liquid chromatography with electrospray ionization time-of-flight tandem mass spectrometry was developed to characterize the phenolics in a methanol extract of red maple leaves and a proprietary phenolic-enriched red maple leaves extract (Maplifa™). Time-of-flight mass spectrometry and tandem mass spectrometry experiments led to the identification of 106 phenolic compounds in red maples leaves with the vast majority of these compounds also detected in Maplifa™. The compounds included 68 gallotannins, 25 flavonoids, gallic acid, quinic acid, catechin, epicatechin, and nine other gallic acid derivatives among which 11 are potentially new and 75 are being reported from red maple for the first time. The developed method to characterize red maple leaves phenolics is rapid and highly sensitive and could aid in future standardization and quality control of this botanical ingredient. © 2018 WILEY-VCH Verlag GmbH & Co.

This study explores if and how teachers combine practices of science and of preschool (children 1-5 years old) into preschool science practice. Views of knowing may differ between science practices, traditionally associated with masculinity and rationality, and preschool practices, traditionally associated with femininity and caring. Recognising this, we have chosen to focus on how teachers' talk constructs and relates to possible ways of gaining knowledge and reaching explanations of phenomena in preschool science. The analysis builds on two concept pairs often associated with gender as well as knowing: objective-subjective and logical-intuitive. The analysed material consists of 11 group interviews where preschool teachers talk about activities concerning science content. Our results show that several ways of knowing are possible in work with science content in preschool. These include ways of knowing more associated with subjectivity, such as `individual liking' and `whole-body perception', as well as more associated with objectivity, such as `noticing differences and similarities'. Furthermore, the results show that the teachers' talk moves readily between possibilities associated with femininity (subjective and intuitive) and masculinity (objective and logical). This indicates that the teachers in this study have found ways to handle science in preschool that goes against presumed tensions between science and preschool practices. The results contribute to more nuanced ways of describing and thinking about science in preschool and pave the way for further development of science education in early childhood education.

Responses to prolonged low-temperature treatment of imbibed seeds (vernalization) were examined in barley (Hordeum vulgare). These occurred in two phases: the perception of prolonged cold, which occurred gradually at low temperatures, and the acceleration of reproductive development, which occurred after vernalization. Expression of the VERNALIZATION1 gene (HvVRN1) increased gradually in germinating seedlings during vernalization, both at the shoot apex and in the developing leaves. This occurred in darkness, independently of VERNALIZATION2 (HvVRN2), consistent with the hypothesis that expression of HvVRN1 is induced by prolonged cold independently of daylength flowering-response pathways. After vernalization, expression of HvVRN1 was maintained in the shoot apex and leaves. This was associated with accelerated inflorescence initiation and with down-regulation of HvVRN2 in the leaves. The largest determinant of HvVRN1 expression levels in vernalized plants was the length of seed vernalization treatment. Daylength did not influence HvVRN1 expression levels in shoot apices and typically did not affect expression in leaves. In the leaves of plants that had experienced a saturating seed vernalization treatment, expression of HvVRN1 was higher in long days, however. HvFT1 was expressed in the leaves of these plants in long days, which might account for the elevated HvVRN1 expression. Long-day up-regulation of HvVRN1 was not required for inflorescence initiation, but might accelerate subsequent stages of inflorescence development. Similar responses to seed vernalization were also observed in wheat (Triticum aestivum). These data support the hypothesis that VRN1 is induced by cold during winter to promote spring flowering in vernalization-responsive cereals. PMID:19357429

Mismatch between cuticle deposition and area expansion in fruit skins allows potentially catastrophic buildup of elastic strain.

The continuous deposition of cutin and wax during leaf and fruit growth is crucial to alleviate elastic strain of the cuticle, minimize the risk of failure and maintain its barrier functions. The cuticular membrane (CM) is a lipoidal biopolymer that covers primary surfaces of terrestrial plants. CMs have barrier functions in water and solute transfer and pathogen invasion. These require intact CMs throughout growth. This is a challenge particularly for fruit, because they increase in area from initiation through to maturity. Our paper investigates the effects of cutin and wax deposition on strain buildup in the CM. We use developing fruits and leaves of apple (Malus × domestica) and sweet cherry (Prunus avium) as models. The hypothesis was that the continuous deposition of the CM prevents the buildup of excessive elastic strain in fruit and leaves. Strains were quantified from decreases in surface area of CMs after isolation from epidermal discs, after wax extraction and from increases in surface area during development. Cuticle mass per unit area increased throughout development in apple fruit, and leaves of apple and sweet cherry. In sweet cherry fruit, however, CM mass increased only initially, but thereafter decreased as the surface expanded rapidly. The release of strain on CM isolation was low in apple fruit and leaves and sweet cherry leaves, but high in sweet cherry fruit. Conversely, strains fixed by the deposition of wax and cutin were high in apple fruit and leaves and sweet cherry leaves, but low in sweet cherry fruit. Our results indicate that in expanding organs, deposition of cutin and wax in the CM allows conversion of elastic to plastic strain. Hence, any lack of such deposition allows buildup of high, potentially catastrophic, elastic strain.

This study examines the development of collaborative relationships between family physicians (FPs) and Anticipatory And Preventative Team Care (APTCare) team members providing care to medically complex patients who have been identified as at-risk for negative health outcomes. We undertook a qualitative study of a primary health care intervention in a family practice. Interviews were held with FPs and ATPCare intervention nurse practitioners (NPs) and pharmacists. Focus groups were conducted and a survey was administered to participating FPs, NPs, and pharmacists. NPs and pharmacists maintained a log recording their tasks and moments of collaboration. Scheduling demands rendered face-to-face collaboration difficult, leaving the team to rely on technological tools to keep in touch. Limited space meant the APTCare team had to work out of a downstairs office, limiting informal interactions with the practitioners on the main level. We demonstrate that the difficulties inherent in collaborative care are independent of the patient population being cared for. Regardless of the patient population and sector of health care, developing collaborative relationships and learning to work collaboratively is difficult and takes time. What many of these teams need is ongoing support and education about how to make these collaborative care practices work.

Background Little research addresses how medical students develop their choice of specialty training in Japan. The purpose of this research was to elucidate factors considered by Japanese medical students when formulating their specialty choice. Methods We conducted qualitative interviews with 25 Japanese medical students regarding factors influencing specialty preference and their views on roles of primary versus specialty care. We qualitatively analyzed the data to identify factors students consider when developing specialty preferences, to understand their views about primary and subspecialty care, and to construct models depicting the pathways to specialization. Results Students mention factors such as illness in self or close others, respect for family member in the profession, preclinical experiences in the curriculum such as labs and dissection, and aspects of patient care such as the clinical atmosphere, charismatic role models, and doctor-patient communication as influential on their specialty preferences. Participating students could generally distinguish between subspecialty care and primary care, but not primary care and family medicine. Our analysis yields a "Two Career" model depicting how medical graduates can first train for hospital-based specialty practice, and then switch to mixed primary/specialty care outpatient practice years later without any requirement for systematic training in principles of primary care practice. Conclusion Preclinical and clinical experiences as well as role models are reported by Japanese students as influential factors when formulating their specialty preferences. Student understanding of family medicine as a discipline is low in Japan. Students with ultimate aspirations to practice outpatient primary care medicine do not need to commit to systematic primary care training after graduation. The Two Career model of specialization leaves the door open for medical graduates to enter primary care practice at anytime regardless of post-graduate residency training choice. PMID:17848194

Correlation of glucosinolate content to myrosinase activity in horseradish (Armoracia rusticana).

Li, Xian; Kushad, Mosbah M

2004-11-17

Fully developed horseradish (Armoracia rusticana Gaertn., Mey., & Scherb.) roots from 27 accessions and leaves from a subset of 9 accessions were evaluated for glucosinolates and myrosinase enzyme activity. Eight different glucosinolates were detected (based on HPLC retention times as desulfoglucosinolates) in both root and leaf tissues. The sum of these glucosinolates, referred to as total, ranged from 2 to 296 micromol g(-1) of dry weight (DW) in both tissues. Four glucosinolates (sinigrin, glucobrassicin, neoglucobrassicin, and gluconasturtiin) were detected in major quantities. In fully developed roots, sinigrin concentration represented approximately 83%, gluconasturtiin approximately 11%, and glucobrassicin approximately 1% of the total glucosinolates. Approximately the same proportions of individual glucosinolates appeared in fully developed leaves, except that glucobrassicin was substituted by neoglucobrassicin and gluconasturtiin concentration was significantly lower (<1%). At least four other glucosinolates were detected in very small quantities (<1%) in both roots and leaves. Myrosinase (beta-thioglucoside glucohydrolase, EC 3.2.3.1) is the enzyme responsible for the hydrolysis of the parent glucosinolates into biologically active products. Very little is known about myrosinase activity and the correlation of its activity to total and individual glucosinolates in plant tissues. Significant differences in myrosinase activity were detected between the roots and leaves, ranging from 1.2 to 57.1 units g(-1) of DW. Data showed no correlation between myrosinase activity and total and/or individual glucosinolates in the roots. However, in the leaves, significant correlations were found between myrosinase activity and total glucosinolates (0.78 at P = 0.01) and between myrosinase activity and sinigrin (0.80 at P = 0.01). Glucosinolates content and myrosinase activity were also correlated in young and fully developed roots and leaves and during tissue crushing. Glucobrassicin concentration in the roots and neoglucobrassicin concentration in the leaves were significantly higher in young than in fully developed tissue. Crushing of the tissue resulted in rapid hydrolysis of sinigrin and glucobrassicin, as expected, from the presence of myrosinase. Likewise, myrosinase activity declined rapidly after crushing, perhaps due to inactivation by the reaction products and/or the depletion of its substrates.

Work-hour restrictions have had a profound impact on surgical training. However, little is known of how work-hour restrictions may affect the future practice patterns of current surgical residents. The purpose of this study is to compare the anticipated career practice patterns of surgical residents who are training within an environment of work-hour restrictions with the current practice of faculty surgeons. An electronic survey was sent to all surgery residents and faculty at 2 Canadian university-affiliated medical centers. The survey consisted of questions regarding expected (residents) or current (faculty) practice patterns. A total of 149 residents and 125 faculty members completed the survey (50.3% and 52.3% response rates, respectively). A greater proportion of males were in the faculty cohort than in the resident group (77.6% vs 62.4%, p = 0.0003). More faculty than residents believed that work-hour restrictions have a negative impact on both residency education (40.8% vs 20.8%, p = 0.008) and preparation for a surgical career (56.8% vs 19.5%, p < 0.0001). Compared with current faculty, residents plan to take less call (p < 0.0003), work fewer days of the week (p < 0.0001), are more likely to limit their duty hours on postcall days (p = 0.009), and take parental leave (p = 0.02) once in practice. Male and female residents differed somewhat in their responses in that more female residents plan to limit their postcall duty hours (55.4% vs 36.5%, p = 0.009) and to take a parental leave (51.8% vs 16.1%, p < 0.0001) compared with their male resident colleagues. Current surgical residents expect to adopt components of resident work-hour guidelines into their surgical practices after completing their residency. These practice patterns will have surgical workforce implications and might require larger surgical groups and reconsideration of resource allocation.

Most of the attrition from nursing courses occurs in the first year of study. Devising university strategies to reduce attrition requires an understanding of why students leave. The aim of this study was to explore whether students who leave a nursing course in the first semester leave for the same or different reasons than students who leave in the second semester of study. Seventeen students who had left the course were interviewed by telephone: seven in the first semester and ten in the second. In the first semester, students who leave consider themselves unprepared for university, have competing roles outside university and develop a strong dislike of the nursing course. They decide quickly that the course is unsuitable and leave. Those who leave in second semester would prefer to stay but events in their life create a crisis where they can no longer cope with university studies. These students hope to return to nursing whereas students who leave in the first semester are unlikely to consider returning. Attempts to retain students in the first semester may be futile as these students may be unsuited or uncommitted whereas there is greater scope to retain those who leave in the second semester.

To develop a comprehensive model of nursing turnover intention by examining the effects of job demands, job resources, personal demands and personal resources on burnout and work engagement and subsequently on the intention to leave the organization and profession. The ageing population and a growing prevalence of multimorbidity are placing increasing strain on an ageing nursing workforce. Solutions that address the anticipated nursing shortage should focus on reducing burnout and enhancing the engagement of Registered Nurses (RNs) to improve retention. A cross-sectional survey design. Data were collected in 2014-2015 via an e-survey from 2,876 RNs working in New Zealand. Data were analysed with structural equation modelling. Higher engagement results in lower intention to leave the organization and profession. Burnout has significant effects on intentions to leave through lower engagement. While most of the demands and resources' variables (except professional development) have effects on intentions to leave, greater workload and greater work-life interference result in higher burnout and are the strongest predictors of intentions to leave. Greater emotional demands (challenges) and greater self-efficacy also have strong effects in lowering intentions to leave through higher engagement. Employee burnout and work engagement play an important role in transmitting the impacts of job demands, job resources, personal demands and personal resources into RN intention to leave the organization and profession. Work-life interference and high workloads are major threats to nursing retention while challenge demands and higher levels of self-efficacy support better retention. © 2017 John Wiley & Sons Ltd.
