    2013-01-01

    The health impact of radionuclide ingestion from foodstuffs was evaluated by the committed effective doses determined in eight commercial samples of South-Brazilian cereal flours (soy, wheat, cornmeal, cassava, rye, oat, barley and rice flours). The radioactivity traces of (228)Th, (228)Ra, (226)Ra, (40)K, (7)Be and (137)Cs were measured by gamma-ray spectrometry employing an HPGe detector of 66 % relative efficiency. The efficiency curve has taken into account the differences in densities and chemical composition between the matrix and the certified sample. The highest concentration levels of (228)Th and (40)K were 3.5±0.4 and 1469±17 Bq kg(-1) for soy flour, respectively, within the 95 % confidence level. The lower limit of detection for (137)Cs ranged from 0.04 to 0.4 Bq kg(-1). The highest committed effective dose was 0.36 μSv.y(-1) for (228)Ra in cassava flour (adults). All committed effective doses determined at the present work were lower than the International Atomic Energy Agency dose limit of 1 mSv.y(-1), to the public exposure.

  6. Protracted exposure to fallout: the Rongelap and Utirik experience.

    1984-03-01

    From June 1946 to August 1958, the U.S. Department of Defense and the U.S. Atomic Energy Commission (AEC) conducted nuclear weapons tests in the Northern Marshall Islands. On 1 March 1954, BRAVO, an above-ground test in the Castle series, produced high levels of radioactive material, some of which subsequently fell on Rongelap and Utirik Atolls due to an unexpected wind shift. On 3 March 1954, the inhabitants of these atolls were moved out of the affected area. They later returned to Utirik in June 1954 and to Rongelap in June 1957. Comprehensive environmental and personnel radiological monitoring programs were initiated in the mid 1950s by Brookhaven National Laboratory to ensure that body burdens of the exposed Marshallese subjects remained within AEC guidelines. Their body-burden histories and calculated activity ingestion rate patterns post-return are presented along with estimates of internal committed effective dose equivalents. External exposure data are also included. In addition, relationships between body burden or urine-activity concentration and declining continuous intake were developed. The implications of these studies are: (1) the dietary intake of 137Cs was a major component contributing to the committed effective dose equivalent for the years after the initial contamination of the atolls; (2) for persons whose diet included fish, 65Zn was a major component of committed effective dose equivalent during the first years post-return; (3) a decline in the daily activity ingestion rate greater than that resulting from radioactive decay of the source was estimated for 137Cs, 65Zn, 90Sr and 60Co; (4) the relative impact of each nuclide on the estimate of committed effective dose equivalent was dependent upon the time interval between initial contamination and rehabilitation; and (5) the internal committed effective dose equivalent exceeded the external dose equivalent by a factor of 1.1 at Utirik and 1.5 at Rongelap during the rehabitation period. Few reliable 239Pu measurements on human excreta were made. An analysis of the tentative data leads to the conclusion that a reliable estimate of committed effective dose equivalent requires further research.

    The Lawrence Livermore National Laboratory (LLNL) annual Environmental Report, prepared for the Department of Energy (DOE) and made available to the public, presents summary environmental data that characterizes site environmental management performance, summarizes environmental occurrences and responses reported during the calendar year, confirms compliance with environmental standards and requirements, and highlights significant programs and efforts. By explaining the results of effluent and environmental monitoring, mentioning environmental performance indicators and performance measure programs, and assessing the impact of Laboratory operations on the environment and the public, the report also demonstrates LLNL's continuing commitment to minimize any potentially adverse impact of itsmore » operations. The combination of environmental and effluent monitoring, source characterization, and dose assessment showed that radiological doses to the public caused by LLNL operations in 2004 were less than 0.26% of regulatory standards and more than 11,000 times smaller than dose from natural background. Analytical results and evaluations generally showed continuing low levels of most contaminants; remediation efforts further reduced the concentrations of contaminants of concern in groundwater and soil vapor. In addition, LLNL's extensive environmental compliance activities related to water, air, endangered species, waste, wastewater, and waste reduction controlled or reduced LLNL's effects on the environment. LLNL's environmental program clearly demonstrates a commitment to protecting the environment from operational impacts.« less

    2010-03-01

    The impact a revision of nuclear decay data had on dose coefficients was studied using data newly published in ICRP Publication 107 (ICRP 107) and existing data from ICRP Publication 38 (ICRP 38). Committed effective dose coefficients for occupational inhalation of radionuclides were calculated using two sets of decay data with the dose and risk calculation software DCAL for 90 elements, 774 nuclides and 1572 cases. The dose coefficients based on ICRP 107 increased by over 10 % compared with those based on ICRP 38 in 98 cases, and decreased by over 10 % in 54 cases. It was foundmore » that the differences in dose coefficients mainly originated from changes in the radiation energy emitted per nuclear transformation. In addition, revisions of the half-lives, radiation types and decay modes also resulted in changes in the dose coefficients.« less

  3. Determination of the uncertainties in radiation doses from ingestion of strontium-90

    NASA Astrophysics Data System (ADS)

    Apostoaei, Andrei Iulian

    Quantification of the uncertainties in the internal dosimetry is important because it can impact the outcome of dose reconstruction, risk assessment or epidemiological studies. This research focused on determination of the uncertainties in the dose factors from a single ingestion of 90Sr by adults, and analyzed the changes with age and the effect of gender. The uncertainties in the estimated dose factors are a factor of 6 for the bone surface, 5 for the red bone marrow, 2.5 for bladder and stomach, 2.2 for the small intestine, 2.1 for the upper large intestine and 2.7 for the lower large intestine. For the rest of the organs the uncertainty is a factor of 3. Only four parameters of the biokinetic model showed an age-dependency within the adult age group: the fractional transfers of strontium from plasma to cortical and trabecular bone, and the removal rates from the cortical and trabecular bone, respectively. When age-dependent biokinetic parameters were used, the estimated dose-factors are very close to the dose factors obtained using age-independent kinetics (within 40%). Thus, the dose factors based on age-independent parameters should suffice for most practical purposes. The dose factors and the associated uncertainties were also calculated as a function of age-at-exposure and attained age. These age dependent curves can be used for estimating doses from continuous intakes, or doses delivered over a limited portion of time. In addition to the committed dose, an expected dose is also estimated in this work. The expected dose is calculated using the dose rate weighted by the probability of surviving up to the age when the dose-rate is delivered. For exposure at young ages the expected dose and the committed dose are similar, but the committed dose decreases to zero when exposure occurs close to age 70, while the expected dose has elevated values pass age 70. No gender differences were found for bone surface, for red bone marrow, and the large intestine. The doses to the soft tissues for females are larger by 20% than the doses for males, because of the differences in the whole-body mass between males and females.

  15. Age-specific radiation dose commitment factors for a one-year chronic intake

    1977-11-01

    During the licensing process for nuclear facilities, radiation doses and dose commitments must be calculated for people in the environs of a nuclear facility. These radiation doses are determined by examining characteristics of population groups, pathways to people, and radionuclides found in those pathways. The pertinent characteristics, which are important in the sense of contributing a significant portion of the total dose, must then be analyzed in depth. Dose factors are generally available for adults, see Reference 1 for example, however numerous improvements in data on decay schemes and half-lives have been made in recent years. In addition, it ismore » advisable to define parameters for calculation of the radiation dose for ages other than adults since the population surrounding nuclear facilities will be composed of various age groups. Further, since infants, children, and teens may have higher rates of intake per unit body mass, it is conceivable that the maximally exposed individual may not be an adult. Thus, it was necessary to develop new radiation-dose commitment factors for various age groups. Dose commitment factors presented in this report have been calculated for a 50-year time period for four age groups.« less

  16. Annual committed effective dose from olive oil (due to 238U, 232Th, and 222Rn) estimated for members of the Moroccan public from ingestion and skin application.

    2012-03-01

    Olive oil is traditionally refined and widely consumed by Moroccan rural populations. Uranium (238U), thorium (232Th), radon (222Rn), and thoron (220Rn) contents were measured in various locally produced olive oil samples collected in rural areas of Morocco. These radionuclides were also measured inside various bottled virgin olive oils consumed by the Moroccan populations. CR-39 and LR-115 type II solid state nuclear track detectors (SSNTDs) were used. Annual committed effective doses due to 238U, 232Th, and 222Rn from the ingestion of olive oil by the members of the general public were determined. The maximum total committed effective dose due to 238U, 232Th, and 222Rn from the ingestion of olive oil by adult members of Moroccan rural populations was found equal to 5.9 µSv y-1. The influence of pollution due to building material dusts and phosphates on the radiation dose to workers from the ingestion of olive oil was investigated, and it was found that the maximum total committed effective dose due to 238U, 232Th, and 222Rn was on the order of 0.22 mSy y-1. Committed effective doses to skin due to 238U, 232Th, and 222Rn from the application of olive oil masks by rural women were evaluated. The maximum total committed effective dose to skin due to 238U, 232Th, and 222Rn was found equal to 0.07 mSy y-1 cm-2.

  17. The Incorporation of Radionuclides After Wounding by a “Dirty Bomb”: The Impact of Time for Decorporation Efficacy and a Model for Cases of Disseminated Fragmentation Wounds

    Objective: In the case of a terrorist attack by a “dirty bomb” there is a risk of internal contamination with radionuclides through inhalation and wounds. We studied the efficacy of a decorporation treatment depending on the initiation time and duration. Approach: Based on biokinetic models, we simulated the impact of different diethylenetriaminepentaacetic acid treatments on the committed effective dose after the incorporation of plutonium-239. Results: For the same level of radioactivity, the dose was higher after the fast absorption from the wound than after a slow invasion following inhalation. The impact of the treatment initiation time was particularly important in the case of the internal contamination through the wound. Ending the treatment at an early point in time was followed by an augmentation of radioactivity in the blood compartment, reflecting insufficient treatment duration. Treatment efficacy increased only marginally if extended over 90 days. Innovation and Conclusion: For plutonium-239, the committed effective dose and the impact of the treatment initiation time on therapeutic efficacy predominantly depend on the speed of invasion, i.e., the pathway and the physicochemical properties of the compounds involved. Thus, it is prudent to start decorporation therapy as soon as possible, as a loss of efficacy resulting from a delay in treatment initiation cannot be compensated later on. In the case of plutonium-239 incorporation, the treatment must be continued for several months. Multiple fragmentation wounds might be aggregated to a single wound model suited for internal dosimetry calculations by using the “rule of nine.” PMID:28116223

    At the Instituto de Pesquisas Energeticas e Nucleares (IPEN), Sao Paulo, Brazil, there is a facility (thorium purification plant) where materials with high thorium concentrations are manipulated. In order to estimate afterwards the lung cancer risk for the workers, the thoron daughter (212Pb) levels were assessed and the committed effective and lung committed equivalent doses for workers in place. A total of 28 air filter samples were measured by total alpha counting through the modified Kusnetz method, to determine the 212Pb concentraion. The committed effective dose and lung committed equivalent dose due to 212Pb inhalation were derived from compartmental analysis following the ICRP 66 lung compartmental model, and ICRP 67 lead metabolic model.

    Uranium (238U) and thorium (232Th) concentrations were measured in different foods widely consumed in Morocco by using CR-39 and LR-115 type II solid state nuclear track detectors (SSNTDs). Annual committed effective doses due to 238U and 232Th intakes from the ingestion of the studied food materials were evaluated for different age groups of individuals, using the ICRP ingestion dose coefficients. The influence of the 238U and 232Th intakes and ages of individuals on the committed effective dose was investigated. Total annual intakes of 238U and 232Th for a typical food basket for adult members of the Moroccan population were estimated to be 451 +/- 27 Bq y(-1) and 359 +/- 20 Bq y(-1), corresponding to committed effective doses of (20 +/- 1) x 10(-6) Sv y(-1) and (83 +/- 5) x 10(-6) Sv y(-1), respectively.

    External dose equivalents and internal dose commitments were estimated for individuals and populations from annual distribution, use, and disposal of 10 million ionization chamber smoke detectors that contain 110 kBq americium-241 each. Under exposure scenarios developed for normal distribution, use, and disposal using the best available information, annual external dose equivalents to average individuals were estimated to range from 4 fSv to 20 nSv for total body and from 7 fSv to 40 nSv for bone. Internal dose commitments to individuals under post disposal scenarios were estimated to range from 0.006 to 80 micro-Sv (0.0006 to 8 mrem) to total body and from 0.06 to 800 micro-Sv to bone. The total collective dose (the sum of external dose equivalents and 50-year internal dose commitments) for all individuals involved with distribution, use, or disposal of 10 million smoke detectors was estimated to be about 0.38 person-Sv (38 person-rem) to total body and 00 ft squared.

  6. Estimates of radiological risk from depleted uranium weapons in war scenarios.

    PubMed

    Durante, Marco; Pugliese, Mariagabriella

    2002-01-01

    Several weapons used during the recent conflict in Yugoslavia contain depleted uranium, including missiles and armor-piercing incendiary rounds. Health concern is related to the use of these weapons, because of the heavy-metal toxicity and radioactivity of uranium. Although chemical toxicity is considered the more important source of health risk related to uranium, radiation exposure has been allegedly related to cancers among veterans of the Balkan conflict, and uranium munitions are a possible source of contamination in the environment. Actual measurements of radioactive contamination are needed to assess the risk. In this paper, a computer simulation is proposed to estimate radiological risk related to different exposure scenarios. Dose caused by inhalation of radioactive aerosols and ground contamination induced by Tomahawk missile impact are simulated using a Gaussian plume model (HOTSPOT code). Environmental contamination and committed dose to the population resident in contaminated areas are predicted by a food-web model (RESRAD code). Small values of committed effective dose equivalent appear to be associated with missile impacts (50-y CEDE < 5 mSv), or population exposure by water-independent pathways (50-y CEDE < 80 mSv). The greatest hazard is related to the water contamination in conditions of effective leaching of uranium in the groundwater (50-y CEDE < 400 mSv). Even in this worst case scenario, the chemical toxicity largely predominates over radiological risk. These computer simulations suggest that little radiological risk is associated to the use of depleted uranium weapons.

    On 17 January 1966, an accident during a refueling operation resulted in the destruction of an air force KC-135 tanker and a B-52 bomber carrying four thermonuclear weapons. Two weapons, whose parachutes opened, were found intact. The others experienced non-nuclear explosion with some burning and release of the fissile fuel at impact. Joint efforts by the United States and Spain resulted in remedial action and a long-term program to monitor the effectiveness of the cleanup. Air concentrations of /sup 239/Pu and /sup 240/Pu have been continuously monitored since the accident. The average annual air concentration for each location was usedmore » to estimate committed dose equivalents for individuals living and working around the air sampling stations.

    2018-04-01

    The equilibrium factor is an important parameter for reasonably estimating the population dose from radon. However, the equilibrium factor value depended mainly on the ventilation rate and the meteorological factors. Therefore, this study focuses on investigating numerically the influence of the ventilation rate, temperature and humidity on equilibrium factor between radon and its progeny. The numerical results showed that ventilation rate, temperature and humidity have significant impacts on indoor equilibrium factor. The variations of equilibrium factor with the ventilation, temperature and relative humidity are discussed. Moreover, the committed equivalent doses due to 218Po and 214Po radon short-lived progeny were evaluated in different tissues of the respiratory tract of the members of the public from the inhalation of indoor air. The annual effective dose due to radon short lived progeny from the inhalation of indoor air by the members of the public was investigated.

  12. Capstone Depleted Uranium Aerosol Biokinetics, Concentrations, and Doses

    Guilmette, Raymond A.; Miller, Guthrie; Parkhurst, MaryAnn

    2009-02-26

    One of the principal goals of the Capstone Depleted Uranium (DU) Aerosol Study was to quantify and characterize DU aerosols generated inside armored vehicles by perforation with a DU penetrator. This study consequently produced a database in which the DU aerosol source terms were specified both physically and chemically for a variety of penetrator-impact geometries and conditions. These source terms were used to calculate radiation doses and uranium concentrations for various scenarios as part of the Capstone DU Human Health Risk Assessment (HHRA). This paper describes the scenario-related biokinetics of uranium, and summarizes intakes, chemical concentrations to the organs, andmore » E(50) and HT(50) for organs and tissues based on exposure scenarios for personnel in vehicles at the time of perforation as well as for first responders. For a given exposure scenario (duration time and breathing rates), the range of DU intakes among the target vehicles and shots was not large, about a factor of 10, with the lowest being from a ventilated operational Abrams tank and the highest being for an unventilated Abrams with DU penetrator perforating DU armor. The ranges of committed effective doses were more scenario-dependent than were intakes. For example, the largest range, a factor of 20, was shown for scenario A, a 1-min exposure, whereas, the range was only a factor of two for the first-responder scenario (E). In general, the committed effective doses were found to be in the tens of mSv. The risks ascribed to these doses are discussed separately.« less

    The purpose of this study is to investigate the impact of multiple leadership qualities (MLQ) on employee commitment in multi-project-based organizsations. The dimensions of leadership qualities develop a healthy organizational environment which will lead to job satisfaction and, ultimately, job commitment. MLQ inspire the subordinates, as collective in nature, to get extra ordinary goals in the hyper competitive era. The main objective of this research is two fold ; firstly, to find out the impact of MLQ on employee job affectiveness and calculative commitment and secondly, to investigate the extent of the impact of MLQ on organizations. A total of 213 respondents were included in the study from different organizations. The data were analyzed through regression analysis by using the SPSS. The finding shows that all of the variables have a positive correlation with each other. The correlation of MLQ and employee job commitment was also found to be significant, which shows that MLQ have an impact on the organizations. Conceptual framework of the study is developed as MLQ an independent variables and its impact has been examined on the Employee Job Commitment. The results supported the hypothesis that MLQ have a positive and significant impact on employee job commitment.

  19. An assessment of the radiological impact of the Windscale reactor fire, October 1957.

    1984-11-01

    On the 10th and 11 October 1957 a fire in the No 1 Pile at the Windscale establishment in Cumbria led to an uncontrolled release of activity to the atmosphere. The resultant cloud subsequently dispersed and radionuclides could be detected over England, Wales and parts of northern Europe. The extensive environmental measurements which were made during and after the release enabled a fairly accurate estimate to be made of the radiation doses to the most exposed individuals in the local population. Until recently, no estimates of the population dose resulting from the release had been published. This paper describes assessments which have been made by the NRPB of the population or collective dose from the release and of the possible associated health impact. In addition to the fission products that escaped, radionuclides were released from materials undergoing irradiation in the pile at the time of the fire. The assessment has included the results of a review of previously unpublished data which established the quantity of these nuclides released and considers their impact on both individual and population doses. The collective effective dose equivalent commitment from the release is estimated to have been 2.0 x 10(3) man Sv. The route of exposure which contributed the most to the collective dose was the inhalation pathway. Iodine-131 was the most important radionuclide, contributing nearly all of the collective dose to the thyroid and a large part of the collective effective dose. Polonium-210 and caesium-137 also made significant contributions; that from caesium-137 came in the longer term via external irradiation from ground deposits and the ingestion of contaminated foodstuffs. The methodology used in the study has been validated to a certain degree by comparing the predicted levels of individual thyroid activity and those measured directly in the weeks following the accident in London, Leeds and Cumbria.

    Building relationships with patients to create patient-centered care is critical to the success of health care organizations. A core element in relationships is commitment. Commitment may be based on affect and emotions, perceived costs, and even obligation. This research proposes that three types of commitment-affective, continuance, and normative commitment-differentially impact consumer purchase loyalty, attitudinal loyalty, and advocacy for a health care provider. To examine the impact of commitment type on consumer relationships, exploratory data were garnered and surveys were administered. Findings are discussed and implications for health care marketing managers in developing successful relationships with consumers are delineated.

    The activity concentrations of alpha-emitters comprising isotopes of uranium (238, 234, 235U) and polonium (210Po) were measured using alpha-particle spectrometry in natural spring waters in the province of Granada, Spain. These water are consumed by the population of the zone who live in villages. This is almost half of the population of the whole region. Mean values of activity concentrations found are 42.61 ± 2.66; 49.55 ± 3.03; 1.64 ± 0.28 and 1.74 ± 0.15 mBq L-1 for 238U, 234U, 235U and 210Po, respectively. Finally, the radiological impact of the analysed waters has been determined, in terms of the estimation of the committed annual effective dose due to the ingestion of the water. The assessment has been carried out for five age groups with the aim to cover all the population. The calculated annual effective doses are observed to be below the prescribed dose limit of 100 μSv y-1 recommended by WHO.

  8. The Long Winding Road of Opioid Substitution Therapy Implementation in South-East Asia: Challenges to Scale Up

    2014-01-01

    The South-East Asia Region contains an estimated 400,000-500,000 people who inject drugs (PWID). HIV prevalence among PWID is commonly 20% or higher in Indonesia, Thailand, Myanmar and some regions of India. Opioid substitution therapy (OST) is an important HIV prevention intervention in this part of the world. However, key challenges and barriers to scale up of OST exist, including: pervasive stigma and discrimination towards PWID; criminalisation of drug use overshadowing a public health response; lack of political will and national commitment; low financial investment; focus towards traditional treatment models of detoxification and rehabilitation; inadequate dosing of OST; and poor monitoring and evaluation of programmes. Our review of local evidence highlights that OST can be successful within the Asian context. Such evidence should be utilised more widely to advocate for policy change and increased political commitment to ensure OST reaches substantially more drug users. Significance for public health Several countries in the World Health Organization South-East Asia Region can be commended for introducing opioid substitution therapy (OST) to address the ongoing HIV epidemic among people who inject drugs (PWID). Local evidence shows OST is an effective drug treatment approach in the Asian context given sufficient technical and institutional support. However, despite much progress, the number of OST dispensing sites and recipients remains totally inadequate in terms of impact upon the current HIV epidemic among PWID. Ongoing advocacy is needed if countries are to achieve the WHO’s target of 40% of PWID being dosed with OST. Greater political commitment a strengthened policy environment, capacity building for OST clinics, lessening the criminalisation of drug use and promoting a public health response will give many more PWID access to OST and slow the advance of the HIV epidemic.

    Variations of Fukushima-derived radionuclides (90Sr, 134Cs and 137Cs) in seawater and biota offshore Fukushima and in the NW Pacific Ocean were investigated and radiation doses to the Japanese and world population from ingestion of seafood contaminated by Fukushima radionuclides were estimated and compared with those from other sources of anthropogenic and natural radionuclides. The total effective dose commitment from ingestion of radionuclides in fish, shellfish and seaweed caught in coastal waters off Fukushima was estimated to be 0.6 ± 0.4 mSv/y. The individual effective dose commitment from consumption of radioactive-contaminated fish caught in the open Pacific Ocean was estimated to be 0.07 ± 0.05 mSv/y. These doses are comparable or much lower than doses delivered from the consumption of natural 210Po in fish and in shellfish (0.7 mSv/y). The estimated individual doses have been below the levels when any health damage of the Japanese and world population could be expected. PMID:25761420

    2003-01-01

    A dose reconstruction study was performed for personnel occupationally exposed to 131I in radiopharmaceutical production, during the years 1981 to 1994, with the objective of estimating committed effective doses and critically reviewing the main causes of their exposures. The workers were selected from a group responsible for the production, labelling and distribution of all radiopharmaceutical material in Brazil. Best estimates of intakes and doses were derived from the examination of the individual monitoring records and the reports from the radiation protection supervisor, complemented by interviews with the workers and with radiation protection officers. Over this time period workers had chronic as well as acute intakes of 131I. Committed effective doses were found to be dependent on the task performed by the worker and the site of operation and inversely correlated with the amounts of iodine handled. Intakes in general were a consequence of inadequate radiation protection control.

    2016-01-01

    The activity concentrations of 210Po have been determined in a total of 24 representative diet samples from Seville (south of Spain), inferring from the obtained values the annual intakes of 210Po by ingestion of the affected population and the corresponding committed effective doses. The annual intakes of 210Po and, consequently, the corresponding doses of this radionuclide show a high variability in correspondence with the variability in the composition of the analysed samples over time, and their magnitude is comparable with the estimated ones in other regions/countries of the world with similar diet habits (countries where the marine products have a considerable weight in the diets). Committed effective doses by ingestion higher than 0.1 mSv y−1 have been estimated exclusively for 210Po, reflecting the importance of this radionuclide and this route of incorporation in the magnitude of the total doses received by the affected population from natural sources.

    To assess internal annual dose in the general public in Aomori Prefecture, Japan, 80 duplicate cooked diet samples, equivalent to the food consumed over a 400-d period by one person, were collected from 100 volunteers in Aomori City and the village of Rokkasho during 2006–2010 and were analyzed for 11 radionuclides. To obtain average rates of ingestion of radionuclides, the volunteers were selected from among office, fisheries, agricultural, and livestock farm workers. Committed effective doses from ingestion of the diet over a 1-y period were calculated from the analytical results and from International Commission on Radiological Protection dose coefficients; for 40K, an internal effective dose rate from the literature was used. Fisheries workers had significantly higher combined internal annual dose than the other workers, possibly because of high rates of ingestion of marine products known to have high 210Po concentrations. The average internal dose rate, weighted by the numbers of households in each worker group in Aomori Prefecture, was estimated at 0.47 mSv y-1. Polonium-210 contributed 49% of this value. The sum of committed effective dose rates for 210Po, 210Pb, 228Ra, and 14C and the effective dose rate of 40K accounted for approximately 99% of the average internal dose rate.

    Research findings have shown that job satisfaction of Chinese nurses is at a low level. Limited studies have focused on the impact of psychological empowerment and organisational commitment on job satisfaction of Chinese nurses. The aim of this study is to describe job satisfaction, psychological empowerment and organisational commitment of Chinese nurses and to explore the impact of psychological empowerment and organisational commitment on the nurses' job satisfaction. A total of 726 nurses were recruited in a convenience sample from 10 tertiary hospitals. Data were collected using four questionnaires including Job Satisfaction Survey, Psychological Empowerment Scale, Organisational Commitment Scale and Demographic Questionnaire. Descriptive analysis, correlation and stepwise multiple regression were used for data analysis. Nurses' job satisfaction, psychological empowerment and organisational commitment were identified at moderate levels. Nurses' job satisfaction and psychological empowerment were significantly different in terms of age and length of service; nurse job satisfaction varied with respect to marital status. Findings further indicated that nurse job satisfaction was positively correlated with psychological empowerment and organisational commitment. Psychological empowerment, organisational commitment and marital status were significant predicting factors of nurse job satisfaction. This study provides evidence to help nursing managers and health policy-makers to develop intervention programs aimed at enhancing nurse job satisfaction and retaining nurses.

    Radioactive contamination in foods is a matter of great concern after the Tokyo Electric Power Company's Fukushima Daiichi nuclear power plant disaster caused by the Great East Japan Earthquake. In order to estimate human intake and annual committed effective dose of radioactive materials, market basket and duplicate diet samples from various areas in Japan were analyzed for cesium-134 ((134)Cs), -137 ((137)Cs), and natural radionuclide potassium-40 ((40)K) by γ-ray spectroscopy. Dietary intake of radioactive cesium around Fukushima area was somewhat higher than in other areas. However, maximum committed effective doses obtained by the market basket and duplicate diet samples were 0.0094 and 0.027 mSv/year, respectively, which are much lower than the maximum permissible dose (1 mSv/year) in foods in Japan.

    The isotope (210)Po was suspected of being involved in the death of a former Russian intelligence agent in 2006 in the UK. Although human exposure to this natural radionuclide in foods is estimated to be high, few studies are available. UNSCEAR Report 2000 does not contain data on (210)Po concentrations of foodstuffs in Japan. We analyzed samples of the everyday Japanese diet cooked with foodstuffs purchased at supermarkets in 7 major domestic cities in 2007-2008. (210)Po was quantified by alpha spectrometry and natural radionuclides such as (40)K by gamma spectrometry. The daily intake and committed effective dose of (210)Po, (40)K, and other natural radionuclides for Japanese adults were calculated. Daily intake was 0.34-1.84 (mean +/- sigma : 0.66 +/- 0.53) and 68.5-94.2 (81.5 +/- 8.5) Bq/d and the committed effective dose was 0.15-0.81 (0.29 +/- 0.24) and 0.16-0.21 (0.18 +/- 0.02) mSv for (210)Po and (40)K, respectively, comprising a high percentage of the total exposure. The total of the mean committed effective dose for the two nuclides (0.47 mSv) was higher than the annual effective dose from ingestion of foods reported by UNSCEAR 2000 (0.29 mSv). The mean committed effective dose of (40)K in the 7 major Japanese cities was comparable to the global average (0.17 mSv). The dietary exposure of Japanese adults can be characterized by a higher (210)Po contribution than in other countries. Of the total daily dietary (210)Po exposure (13 food categories excluding water) for adults in Yokohama, about 70% was from fish/shellfish and 20% from vegetables/mushrooms/seaweeds, reflecting preferences of Japanese to eat a considerable amount of fish/shellfish containing high (210)Po concentrations.

    This Site Environmental Report for Calendar Year 1993 describes the environmental monitoring programs at the Weldon Spring Site Remedial Action Project (WSSRAP). The objectives of these programs are to assess actual or potential exposure to contaminant effluents from the project area by providing public use scenarios and dose estimates, to demonstrate compliance with Federal and State permitted levels, and to summarize trends and/or changes in contaminant concentrations from environmental monitoring program. In 1993, the maximum committed dose to a hypothetical individual at the chemical plant site perimeter was 0.03 mrem (0.0003 mSv). The maximum committed dose to a hypothetical individualmore » at the boundary of the Weldon Spring Quarry was 1.9 mrem (0.019 mSv). These scenarios assume an individual walking along the perimeter of the site-once a day at the chemical plant/raffinate pits and twice a day at the quarry-250 days per year. This hypothetical individual also consumes fish, sediment, and water from lakes and other bodies of water in the area. The collective dose, based on an effected population of 112,000 was 0.12 person-rem (0.0012 person-Sv). This calculation is based on recreational use of the August A. Busch Memorial Conservation Area and the Missouri Department of Conservation recreational trail (the Katy Trail) near the quarry. These estimates are below the U.S. Department of Energy requirement of 100 mrem (I mSv) annual committed effective dose equivalent for all exposure pathways. Results from air monitoring for the National Emission Standards for Hazardous Air Pollutants (NESHAPs) program indicated that the estimated dose was 0.38 mrem, which is below the U.S. Environmental Protection Agency (EPA) standard of 10 mrem per year.« less

    The activity concentrations of (210)Po have been determined in a total of 24 representative diet samples from Seville (south of Spain), inferring from the obtained values the annual intakes of (210)Po by ingestion of the affected population and the corresponding committed effective doses. The annual intakes of (210)Po and, consequently, the corresponding doses of this radionuclide show a high variability in correspondence with the variability in the composition of the analysed samples over time, and their magnitude is comparable with the estimated ones in other regions/countries of the world with similar diet habits (countries where the marine products have a considerable weight in the diets). Committed effective doses by ingestion higher than 0.1 mSv y(-1) have been estimated exclusively for (210)Po, reflecting the importance of this radionuclide and this route of incorporation in the magnitude of the total doses received by the affected population from natural sources. © The Author 2015.

    2016-09-01

    This study seeks to examine the relationship and impact of occupational health and safety on employees' organizational commitment in Ghana's mining industry. The study explores occupational health and safety and the different dimensions of organizational commitment. A cross-sectional survey design was used for this study. The respondents were selected based on simple random sampling. Out of 400 questionnaires administered, 370 were returned (77.3% male and 22.7% female) and used for the study. Correlation and multiple regression analysis were used to determine the relationship and impact between the variables. The findings of this study revealed positive and significant relationship between occupational health and safety management, and affective, normative, and continuance commitment. Additionally, the results revealed the significant impact of occupational health and safety on affective, normative, and continuance commitment. Management within the mining sector of Ghana must recognize the fact that workers who feel healthy and safe in the performance of their duties, develop emotional attachment and have a sense of obligation to their organization and are most likely committed to the organization. Employees do not just become committed to the organization; rather, they expect management to first think about their health and safety needs by instituting good and sound policy measures. Thus, management should invest in the protection of employees' health and safety in organizations.

    2009-05-01

    The aim of this study was to test a multilevel model linking unit-level leader-member exchange quality and structural empowerment to nurses' psychological empowerment and organizational commitment at the individual level of analysis. Few studies have examined the contextual effects of unit leadership on individual nurse outcomes. Workplace empowerment has been related to retention outcomes such as organizational commitment in several studies, but few have studied the impact of specific unit characteristics within which nurses work on these outcomes. We surveyed 3,156 nurses in 217 hospital units to test the multilevel model. A multilevel path analysis revealed significant individual and contextual effects on nurses' organizational commitment. Both unit-level leader-member exchange quality and structural empowerment had significant direct effects on individual-level psychological empowerment and organizational commitment. Psychological empowerment mediated the relationship between core self-evaluations and organizational commitment at the individual level of analysis. The contextual effects of positive supervisor relationships and their influence on empowering working conditions at the unit level and, subsequently, nurses' organizational commitment highlight the importance of leadership for creating conditions that result in a committed nursing workforce.

    Radionuclides handled in nuclear medicine departments are often characterized by high volatility and short half-life. It is generally difficult to monitor directly the intake of these short-lived radionuclides in hospital staff: this makes measuring air contamination of utmost interest. The aim of the present work is to provide a method for the evaluation of internal doses to workers in nuclear medicine, by means of an air activity sampling detector, to ensure that the limits prescribed by the relevant legislation are respected. A continuous air sampling system measures isotope concentration with a Nal(TI) detector. Energy efficiency of the system was assessed with GEANT4 and with known activities of 18F. Air is sampled in a number of areas of the nuclear medicine department of the IRST-IRCCS hospital (Meldola- Italy). To evaluate committed doses to hospital staff involved (doctors, technicians, nurses) different exposure situations (rooms, times, radionuclides etc) were considered. After estimating the intake, the committed effective dose has been evaluated, for the different radionuclides, using the dose coefficients mandated by the Italian legislation. Error propagation for the estimated intake and personal dose has been evaluated, starting from measurement statistics.

  4. New Stochastic Annual Limits on Intake for Selected Radionuclides

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

    Carbaugh, Eugene H.

    Annual limits on intake (ALI) have historically been tabulated by the International Commission on Radiological Protection (e.g., ICRP 1979, 1961) and also by the Environmental Protection Agency (EPA 1988). These compilations have been rendered obsolete by more recent ICRP dosimetry methods, and, rather than provide new ALIs, the ICRP has opted instead to provide committed dose coefficients from which an ALI can be determined by a user for a specific set of conditions. The U.S. Department of Energy historically has referenced compilations of ALIs and has defined their method of calculation in its radiation protection regulation (10 CFDR 835), butmore » has never provided a specific compilation. Under June 2007 amendments to 10 CFR 835, ALIs can be calculated by dividing an appropriate dose limit, either 5-rem (0.05 Sv) effective dose or 50 rem (0.5 Sv) equivalent dose to an individual organ or tissue, by an appropriate committed dose coefficient. When based on effective dose, the ALI is often referred to as a stochastic annual limit on intake (SALI), and when based on the individual organ or tissue equivalent limit, it has often been called a deterministic annual limit on intake (DALI).« less

    Nursing has a high risk of job burnout, but only a few studies have explored its influencing factors from an organizational perspective. The present study explores the impact of psychological capital on job burnout by investigating the mediating effect of organizational commitment on this relationship. A total of 473 female nurses from four large general hospitals in Xi'an City of China were selected as participants. Data were collected via the Psychological Capital Questionnaire, the Maslach Burnout Inventory-General Survey, and the Organizational Commitment Scale. Both psychological capital and organizational commitment were significantly correlated to job burnout. Structural equation modelling indicated that organizational commitment partially mediated the relationship between psychological capital and job burnout. The final model revealed a significant path from psychological capital to job burnout through organizational commitment. These findings extended prior reports and shed some light on the influence of psychological capital on job burnout.

    Factors associated with family commitment among pharmacists in the south central U.S. are explored. In 2010, a cross-sectional mailed self-administered 70 item survey of 363 active licensed pharmacists was conducted. This analysis includes only 269 (74%) participants who reported being married. Outcome measures were family commitment (need for family commitment, spouse’s family commitment), work-related characteristics (work challenge, stress, workload, flexibility of work schedule), and job and career satisfaction. Married participants’ mean age was 48 (SD = 18) years; the male to female ratio was 1:1; 73% worked in retail settings and 199 (74%) completed the family commitment questions. Females reported a higher need for family commitment than males (p = 0.02) but there was no significant difference in satisfaction with the commitment. Work challenge and work load were significantly associated with higher need for family commitment (p < 0.01), when controlled for age, gender, number of dependents, work status, and practice setting. Higher work challenge was associated with higher career satisfaction. Higher job related stress was associated with lower job satisfaction. High work challenge and work load may negatively impact family function since married pharmacists would need higher family commitment from their counterparts. The impact of work-family interactions on pharmacy career satisfaction should be further investigated. PMID:28975924

    A primary aim of the pilot phase of the Act-Belong-Commit mental health promotion campaign was to form partnerships with community organisations. As a component of the broader campaign strategy, collaborating organisations promoted their activities under the Act-Belong-Commit banner in exchange for resources, promotional opportunities and capacity building in event management and funding. The impact of the Act-Belong-Commit campaign on the capacity and activities of collaborating organisations during the pilot phase was evaluated using self-completed mail surveys in 2006 and 2008. Collaboration with the campaign had a positive impact on community organisations' capacity, including staff expertise, media publicity and funding applications. Collaborating organisations had strong positive perceptions of Act-Belong-Commit officers and all expressed a willingness to collaborate in future events and activities. The partnership model used during the pilot phase of the Act-Belong-Commit campaign was successful in creating mutually beneficial exchanges with collaborating organisations. So what? Community partnerships are necessary for the effective delivery of mental health promotion campaigns at a local level. Successful partnerships involve the provision of real and valuable benefits to collaborating organisations in return for their cooperation in promoting health messages.

    This report presents internal radiation dose conversion factors for radionuclides of interest in environmental assessments of nuclear fuel cycles. This volume provides an updated summary of estimates of committed dose equivalent for radionuclides considered in three previous Oak Ridge National Laboratory (ORNL) reports. Intakes by inhalation and ingestion are considered. The International Commission on Radiological Protection (ICRP) Task Group Lung Model has been used to simulate the deposition and retention of particulate matter in the respiratory tract. Results corresponding to activity median aerodynamic diameters (AMAD) of 0.3, 1.0, and 5.0 ..mu..m are given. The gastorintestinal (GI) tract has been representedmore » by a four-segment catenary model with exponential transfer of radioactivity from one segment to the next. Retention of radionuclides in systemic organs is characterized by linear combinations of decaying exponential functions, recommended in ICRP Publication 30. The first-year annual dose rate, maximum annual dose rate, and fifty-year dose commitment per microcurie intake of each radionuclide is given for selected target organs and the effective dose equivalent. These estimates include contributions from specified source organs plus the systemic activity residing in the rest of the body; cross irradiation due to penetrating radiations has been incorporated into these estimates. 15 references.« less

  10. Seasonal influenza vaccine dose distribution in 195 countries (2004-2013): Little progress in estimated global vaccination coverage.

    2015-10-13

    Seasonal influenza is an important disease which results in 250,000-500,000 annual deaths worldwide. Global targets for vaccination coverage rates (VCRs) in high-risk groups are at least 75% in adults ≥65 years and increased coverage in other risk groups. The International Federation of Pharmaceutical Manufacturers and Associations Influenza Vaccine Supply (IFPMA IVS) International Task Force developed a survey methodology in 2008, to assess the global distribution of influenza vaccine doses as a proxy for VCRs. This paper updates the previous survey results on absolute numbers of influenza vaccine doses distributed between 2004 and 2013 inclusive, and dose distribution rates per 1000 population, and provides a qualitative assessment of the principal enablers and barriers to seasonal influenza vaccination. The two main findings from the quantitative portion of the survey are the continued negative trend for dose distribution in the EURO region and the perpetuation of appreciable differences in scale of dose distribution between WHO regions, with no observed convergence in the rates of doses distributed per 1000 population over time. The main findings from the qualitative portion of the survey were that actively managing the vaccination program in real-time and ensuring political commitment to vaccination are important enablers of vaccination, whereas insufficient access to vaccination and lack of political commitment to seasonal influenza vaccination programs are likely contributing to vaccination target failures. In all regions of the world, seasonal influenza vaccination is underutilized as a public health tool. The survey provides evidence of lost opportunity to protect populations against potentially serious influenza-associated disease. We call on the national and international public health communities to re-evaluate their political commitment to the prevention of the annual influenza disease burden and to develop a systematic approach to improve vaccine distribution equitably.

    (210)Po is a naturally occurring radionuclide, belonging to the uranium series, which is present in minute amounts in the different environmental compartments (water, soil, biota). Through its route along the trophic chain, it can be incorporated in the human body via ingestion of waters and/or food. This radionuclide is highly radiotoxic, being one of the main contributors to the committed effective dose via ingestion by the general population. In this work, the contribution of this radionuclide to the committed effective dose received by the Spanish population via consumption of bottled mineral waters is evaluated. With this end, the (210)Po activity concentrations in a total of 32 different commercial bottled mineral waters have been determined by alpha-particle spectrometry. The determined contribution is also compared with the contributions of other natural radionuclides such as (234)U and (238)U.

    The personal spiritual health of nurses may play an important role in improving their attitudes toward spiritual care and their professional commitment and caring capabilities. The purpose of this study was to explore the impact of nurses' personal spiritual health on their attitudes toward spiritual care, professional commitment, and caring. A total of 619 clinical nurses were included in this cross-sectional survey. The measurements included the spiritual health scale-short form, the spiritual care attitude scale, the nurses' professional commitment scale, and the caring behaviors scale. Structural equation modeling was used to establish associations between the main research variables. The hypothetical model provided a good fit with the data. Nurses' spiritual health had a positive effect on nurses' professional commitment and caring. Nurses' attitudes toward spiritual care could therefore mediate their personal spiritual health, professional commitment, and caring. The findings indicated that nurses' personal spiritual health is an important value and belief system and can influence their attitudes toward spiritual care, professional commitment, and caring.

    The purpose of this paper is to develop a causal model that explains the antecedents and mediating factors predicting the organizational commitment of healthcare employees in different work roles. This study tests an integrative causal model that consists of a number of direct and indirect relationships for antecedents of organizational commitment. It is proposed that the relationship between job satisfaction and organizational commitment is best understood by focusing on the three interrelated facets of job satisfaction, i.e. satisfaction with career advancement, satisfaction with supervisor, and satisfaction with co-workers. However, the model also advances that these job satisfaction facets have different mediating effects for other antecedents of organizational commitment. The Structural Equation Modeling (SEM) path analysis showed that the job satisfaction facets of career advancement and satisfaction with supervisor had a direct impact on organizational commitment. Employee empowerment, job-motivating potential, effective leadership, acceptance by co-workers, role ambiguity and role conflict were also important determinants of organizational commitment. Interestingly, post hoc analyses showed that satisfaction with co-workers only had an indirect impact on organizational commitment. While there has been extensive research on organizational commitment and its antecedents in healthcare organizations, most previous studies have been limited either to a single employee group or to a single time frame. This study proposes a practical causal model of antecedents of organizational commitment that tests relationships across time and across different healthcare employee groups.

    Background Although previous studies proved that the implementation of mentoring program is beneficial for enhancing the nursing skills and attitudes, few researchers devoted to exploring the impact of mentoring functions on job satisfaction and organizational commitment of new nurses. In this research we aimed at examining the effects of mentoring functions on the job satisfaction and organizational commitment of new nurses in Taiwan's hospitals. Methods We employed self-administered questionnaires to collect research data and select new nurses from three regional hospitals as samples in Taiwan. In all, 306 nurse samples were obtained. We adopted a multiple regression analysis to test the impact of the mentoring functions. Results Results revealed that career development and role modeling functions have positive effects on the job satisfaction and organizational commitment of new nurses; however, the psychosocial support function was incapable of providing adequate explanation for these work outcomes. Conclusion It is suggested in this study that nurse managers should improve the career development and role modeling functions of mentoring in order to enhance the job satisfaction and organizational commitment of new nurses.

To explore the exposure pathway of (238)U, (232)Th and (222)Rn to the skin of bathers from the immersion in thermal waters, these radionuclides were measured inside waters collected from different Moroccan thermal springs, by means of CR-39 and LR-115 type II solid-state nuclear track detectors (SSNTDs), and corresponding annual committed effective doses to skin were determined. Accordingly, to assess radiation dose due to radon short-lived decay products from the inhalation of air by individuals, concentrations of these radionuclides were measured in indoor air of two thermal stations by evaluating mean critical angles of etching of the CR-39 and LR-115 II SSNTDs. Committed effective doses due to the short-lived radon decay products (218)Po and (214)Po by bathers and working personnel inside the thermal stations studied were determined.

    One of the curses to the society is a crime which has a deep impact on the society. Victims of crimes are the one who is impacted the most. All communities in the world are affected by crime and the criminal justice system, but largely impacted communities are the backward classes. There are many cases reported of crime committed against scheduled tribes from the year 2005 till date. This paper states the analysis of Crimes Committed against Scheduled Tribes in the year 2015 in various states and union territories in India. In this study, Multiple Linear regression techniques have been used to analyze the crimes committed against scheduled tribes’ community in India. This study compares the number of cases reported to the police station and rate of crime committed in different states in India. It also states the future prediction of the crime that would happen. It will also predict the number of cases of crime committed against the scheduled tribe that can be reported in future. The dataset which has been used in this study is taken from official Indian government repository for crimes which include different information of crimes committed against scheduled tribes in different states and union territories measured under the population census of the year 2011. This study will help different Indian states and union territory government to analyze and predict the future crimes that may occur and take appropriate measures against it before the actual crime would occur.

    We investigate the sensitivity of IMRT commissioning using the TG-119 C-shape phantom and credentialing with the IROC head and neck phantom to treatment planning system commissioning errors. We introduced errors into the various aspects of the commissioning process for a 6X photon energy modeled using the analytical anisotropic algorithm within a commercial treatment planning system. Errors were implemented into the various components of the dose calculation algorithm including primary photons, secondary photons, electron contamination, and MLC parameters. For each error we evaluated the probability that it could be committed unknowingly during the dose algorithm commissioning stage, and the probability of it being identified during the verification stage. The clinical impact of each commissioning error was evaluated using representative IMRT plans including low and intermediate risk prostate, head and neck, mesothelioma, and scalp; the sensitivity of the TG-119 and IROC phantoms was evaluated by comparing dosimetric changes to the dose planes where film measurements occur and change in point doses where dosimeter measurements occur. No commissioning errors were found to have both a low probability of detection and high clinical severity. When errors do occur, the IROC credentialing and TG 119 commissioning criteria are generally effective at detecting them; however, for the IROC phantom, OAR point-dose measurements are the most sensitive despite being currently excluded from IROC analysis. Point-dose measurements with an absolute dose constraint were the most effective at detecting errors, while film analysis using a gamma comparison and the IROC film distance to agreement criteria were less effective at detecting the specific commissioning errors implemented here.

    This study investigates the mediating impact of organizational commitment on the relationship between organizational stressors and employee health and well-being. Data were collected from 401 operator level employees working in business process outsourcing organizations (BPOs) based in New Delhi, India. In this research several dimensions from ASSET, which is an organizational stress screening tool, were used to measure employee perceptions of stressors, their commitment to the organization, their perception of the organization’s commitment to them, and their health and well-being. Data were analyzed using structural equation modeling on AMOS software. Results of the mediation analysis highlight both employee commitment to their organization and their perceptions of the organization’s commitment to them mediate the impact of stressors on physical health and psychological well-being. All indices of the model fit were found to be above standard norms. Implications are discussed with the view to improving standards of health and well-being within the call center industry, which is a sector that has reported higher turnover rates and poor working conditions among its employees internationally.

    The aim was to examine the relationship between the quality of team-member exchange experienced by nursing staff and their intention to leave. Job satisfaction and affective organizational commitment are considered as mediators. While the shortage of nurses is a management and policy priority, few studies have studied the relationships between nursing staff and their team, key organizational attitudes, and intentions to leave the organization. A questionnaire was administered to 217 registered nurses and nurse assistants in Belgium. Data were collected in 2012. To analyse the data, descriptive statistics, correlation, regression and path analyses were conducted. Team-member exchange has a positive impact on nursing staff satisfaction and affective commitment. Job satisfaction and affective organizational commitment fully mediated the impact of team-member exchange on nursing staff's intention to leave. This study illustrates the potential benefits of the positive influence of team-member exchange on key organizational attitudes of nursing staff, and the negative influence on intention to leave through affective commitment and job satisfaction. © 2015 International Council of Nurses.

    Cigarette smoking is a source of radiation exposure due to the concentrations of natural radionuclides in the tobacco leaves. From the health point of view, measurement of (210)Pb and (210)Po contents in cigarette tobacco is important to assess the radiological effects associated with the tobacco smoking for the smokers. In the present study, activity concentrations of (210)Pb, which is a (210)Po precursor in the (238)U-decay series, were measured in cigarette tobaccos. Samples of nine different commonly sold brands of cigarette tobaccos were analysed by employing a planar high purity germanium (HPGe) low background detector. Activity concentrations of (210)Pb were measured from its gamma peak at 47 keV. Mean activity concentration of (210)Pb was measured to be 13 +/- 4 Bq kg(-1) from all samples analysed. The annual committed effective dose for a smoker and the collective committed effective dose corresponding to annual cigarettes production were estimated to be 64 +/- 20 microSv and 0.6 x 10(2) man-Sv, respectively.

    The effects of transformational leadership on the outcomes of specific change initiatives are not well understood. Conversely, organizational change studies have examined leader behaviors during specific change implementations yet have failed to link these to broader leadership theories. In this study, the authors investigate the relationship between transformational and change leadership and followers' commitment to a particular change initiative as a function of the personal impact of the changes. Transformational leadership was found to be more strongly related to followers' change commitment than change-specific leadership practices, especially when the change had significant personal impact. For leaders who were not viewed as transformational, good change-management practices were found to be associated with higher levels of change commitment. Copyright 2008 APA

    To examine the effect of transformational leadership on early career nurses' intent to stay, job satisfaction and organizational commitment. Lack of leadership support is one of the top reasons staff nurses leave. Current studies reported mixed results about the impact of transformational leadership on key nurse outcomes. However, little is known whether leadership directly or indirectly affects satisfaction, organizational commitment and intent to stay. This study was a cross-sectional study of nurses who had been licensed for 7·5-8·5 years which was part of a 10-year longitudinal panel design. The analytic sample was 1037 nationally representative newly licensed Registered Nurses. Data were collected from January-March 2013. We used a probit model to model the relationship between transformational leadership and intent to stay, organizational commitment and job satisfaction. Transformational leadership did not have a significant impact on intent to stay and job satisfaction, but significantly associated with organizational commitment. Organizational commitment, job satisfaction, mentor support, promotional opportunities and age were positively associated with intent to stay, while ethnicity, non-local job opportunities and work settings were negatively associated with intent to stay. Transformational leadership had no direct relationship with intent to stay and job satisfaction and had a small direct positive effect on organizational commitment. Transformational leadership has potential to slow attrition and retain nurses by creating a positive work environment that supports nurses. Any improvement in job satisfaction and organizational commitment would positively increase the change in probability for intent to stay. © 2016 John Wiley & Sons Ltd.

    2014-01-01

    This study investigated how coach and teammates influence masters athletes' sport commitment, and the effect of functional and obligatory commitments on participation in masters swimming. The sample consisted of 523 masters swimmers (330 males and 193 females) aged between 22 and 83 years (M = 39.00, SD = 10.42). A bi-dimensional commitment scale was used to measure commitment dimensions and perceived influence from social agents. Structural equation modelling analysis was conducted to evaluate the influence of social agents on functional and obligatory commitments, and the predictive capabilities of the two types of commitment towards sport participation. Support provided by coach and teammates increased functional commitment, constraints from these social agents determined higher obligatory commitment, and coach constraints negatively impacted functional commitment. In addition, both commitment types predicted training participation, with functional commitment increasing participation in team training sessions, and obligatory commitment increasing the hours of individual training. The findings suggest that in order to increase participation in masters swimming teams and reduce non-supervised training, coach and teammates should exhibit a supportive attitude and avoid over expectation.

    The effectiveness of an intervention depends on its dose and on moderators of dose, which usually are not studied. The purpose of the study is to determine whether goal setting and theory-based moderators of goal setting had dose relations with increases in goal-related physical activity during a successful workplace intervention. A group-randomized 12-week intervention that included personal goal setting was implemented in fall 2005, with a multiracial/ethnic sample of employees at 16 geographically diverse worksites. Here, we examined dose-related variables in the cohort of participants (N = 664) from the 8 worksites randomized to the intervention. Participants in the intervention exceeded 9000 daily pedometer steps and 300 weekly minutes of moderate-to-vigorous physical activity (MVPA) during the last 6 weeks of the study, which approximated or exceeded current public health guidelines. Linear growth modeling indicated that participants who set higher goals and sustained higher levels of self-efficacy, commitment and intention about attaining their goals had greater increases in pedometer steps and MVPA. The relation between change in participants' satisfaction with current physical activity and increases in physical activity was mediated by increases in self-set goals. The results show a dose relation of increased physical activity with changes in goal setting, satisfaction, self-efficacy, commitment and intention, consistent with goal-setting theory.

    The results of gross alpha and beta radioactivity measurement in water spinach samples from some districts in Ho Chi Minh City, Vietnam are presented in this paper. The measurements were performed using a low-background proportional counters LB4200 manufactured by Canberra Company, Inc. Mean concentrations of gross alpha and beta activity were found to be 1.50 ± 0.38 Bq kg -1 to 84.25 ± 8.67 Bq kg -1 . In order to keep the recommended dose level, a recommended maximum intake of water spinach was proposed to be 6 kg fresh per year. The total annual committed effective dose due to natural radionuclides in water spinach samples was then found in range from 0.07 mSv y -1 to 0.82 mSv y -1 . The dose from 26.32% of samples exceeds the exemption mean dose criterion of 0.3 mSv y -1 but complies with the upper dose principle of 1 mSv y -1 provided in UNSCEAR 2008 report. The estimated soil-to-plant transfer factors for gross alpha and beta for water spinach samples were also presented. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To date, there is surprisingly little research on differences in the prevalence and impact of risk factors for general recidivism between juveniles who have committed sexual offenses (JSO) and juveniles who have committed nonsexual offenses (NSO). Therefore, we examined differences in the prevalence and impact of dynamic risk factors for general delinquency between youth with nonsexual offenses (NSO, n = 504), youth with misdemeanor sexual offenders (MSO, n = 136), youth with felony sexual offenders (FSO, n = 116) and youth with offenses against much younger children (CSO, n = 373). The sample consisted of boys with a mean age of 15.3 years (SD = 1.5). The prevalence of dynamic risk factors for general delinquency was significantly lower in JSOs than in NSOs. More serious sexual offenses were associated with a lower prevalence of dynamic risk factors. In contrast, the impact of most dynamic risk factors on general recidivism proved to be significantly larger among JSOs compared to NSOs. The relative importance of the dynamic risk factors varied for each type of JSO, resulting in differences in the dynamic risk profiles of the various types of JSOs.

  6. Impact of organizational climate on organizational commitment and perceived organizational performance: empirical evidence from public hospitals.

    Extant literature suggested that positive organizational climate leads to higher levels of organizational commitment, which is an important concept in terms of employee attitudes, likewise, the concept of perceived organizational performance, which can be assumed as a mirror of the actual performance. For healthcare settings, these are important matters to consider due to the fact that the service is delivered thoroughly by healthcare workers to the patients. Therefore, attitudes and perceptions of the employees can influence how they deliver the service. The aim of this study was to evaluate healthcare employees' perceptions of organizational climate and test the hypothesized impact of organizational climate on organizational commitment and perceived organizational performance. The study adopted a quantitative approach, by collecting data from the healthcare workers currently employed in public hospitals in North Cyprus, utilizing a self-administered questionnaire. Collected data was analyzed with the help of Statistical Package for Social Sciences, and ANOVA and Linear Regression analyses were used to test the hypothesis. Results revealed that organizational climate is highly correlated with organizational commitment and perceived organizational performance. Simple linear regression outcomes indicated that organizational climate is significant in predicting organizational commitment and perceived organizational performance. There was a positive and linear relationship between organizational climate with organizational commitment and perceived organizational performance. Results from the regression analysis suggested that organizational climate has an impact on predicting organizational commitment and perceived organizational performance of the employees in public hospitals of North Cyprus. Organizational climate was found to be statistically significant in determining the organizational commitment of the employees. The results of the study provided some critical issues regarding the relationship of three concepts in the study. According to the findings, if the organizational climate scores of the employees are high, organizational commitment scores of the employees are high at the same time. In other words, if the employees in public hospitals of North Cyprus perceive the organizational climate in a positive way, they will have higher levels of organizational commitment. Findings suggested that organizational climate is an important factor in healthcare settings in terms of employee commitment and how employees perceive organizational performance, which would lead to significant results about the provision of service in healthcare organizations.

    Talent is the core competitiveness of an enterprise, how to retain talent, inspire their creative, exert its advantages for the enterprise to bring profit maximization and value appreciation. It has always been the focus of enterprises and scholars. A great number of studies have shown that organizational commitment has an important impact on employees’ attitudes, thoughts and behaviors, and leadership style is also an important variable which affects the organizational commitment of employees. Through the questionnaire survey, the statistical software SPSS24.0 empirical analysis of the collected data shows that there is a positive correlation between the style of leadership and the commitment of the employee and the correlation with the employee’s normative commitment is not significant; The established leadership is negatively correlated with the employee’s emotional commitment and normative commitment, but it is not significant with the continuous commitment.

    2009-09-01

    An individual's loyalty or bond to his or her employing organization, referred to as organizational commitment, influences various organizational outcomes such as employee motivation, job satisfaction, performance, accomplishment of organizational goals, employee turnover, and absenteeism. Therefore, as in other sectors, employee commitment is crucial also in the healthcare market. This study investigates the effects of organizational factors and personal characteristics on organizational commitment of military physicians using structural equation modeling (SEM) on a self-report, cross-sectional survey that consisted of 635 physicians working in the 2 biggest military hospitals in Turkey. The results of this study indicate that professional commitment and organizational incentives contribute positively to organizational commitment, whereas conflict with organizational goals makes a significantly negative contribution to it. These results might help develop strategies to increase employee commitment, especially in healthcare organizations, because job-related factors have been found to possess greater impact on organizational commitment than personal characteristics.

    2007-01-01

    The purpose of this paper is to explore the impact of hospital emergency department culture on the job satisfaction, patient commitment, and extra-role performance of Canadian emergency physicians. The conceptual model related four cultural archetypes from the competing valued model to the three outcome variables. In total, 428 Canadian emergency physicians responded to a national survey. The conceptual model was tested via structural equation modeling via LISREL 8. Culture had a relatively weak impact on the outcomes. Human resources culture related positively to job satisfaction while bureaucratic culture related positively to patient commitment. Patient commitment, but not job satisfaction strongly and positively related to extra-role behavior. A direct relationship between entrepreneurial culture and extra-role behavior emerged from an extended analysis. Organizational culture seems to have more distal relationships with outcome variables and its influence is likely to be mediated by more proximal workplace variables. Of value by showing that a key modern leadership challenge is to create the kind of work culture that can become a source of competitive advantage through generating particular organizational outcomes valued by stakeholders.

    The present study explored treatment dose and patient engagement as predictors of treatment outcome in cognitive behavioral therapy (CBT) for anxiety disorders. Measures of high versus low treatment dose and high versus low patient engagement in CBT were compared as predictors of 12- and 18-month outcomes for patients being treated for anxiety disorders with CBT (with or without concurrent pharmacotherapy) in primary care settings as part of a randomized controlled effectiveness trial of the Coordinated Anxiety Learning and Management (CALM) intervention. Measures of dose (attendance, exposure completion) and engagement in CBT (homework adherence, commitment) were collected throughout treatment, and blinded follow-up phone assessments of outcome measures (12-item Brief Symptom Inventory, Patient Health Questionnaire 8, Sheehan Disability Scale) were completed at 12 and 18 months. Propensity score weighting controlled for baseline differences in demographics and symptom severity between patients with high and low dose and engagement. These analyses included the 439 patients who selected CBT as treatment modality. Completing exposures, having high attendance, and being more adherent to completing homework predicted better outcomes across all measures at 12 and 18 months, and high CBT commitment predicted better outcomes on all measures at 18 months. This study found that higher treatment dose and patient engagement in CBT for anxiety disorders were stable and robust predictors of greater reductions in anxiety symptoms, depression symptoms, and functional disability.

    2012-11-01

    We study how the presence of committed vaccinators, a small fraction of individuals who consistently hold the vaccinating strategy and are immune to influence, impact the vaccination dynamics in well-mixed and spatially structured populations. For this purpose, we develop an epidemiological game-theoretic model of a flu-like vaccination by integrating an epidemiological process into a simple agent-based model of adaptive learning, where individuals (except for those committed ones) use anecdotal evidence to estimate costs and benefits of vaccination. We show that the committed vaccinators, acting as “steadfast role models” in the populations, can efficiently avoid the clustering of susceptible individuals and stimulate other imitators to take vaccination, hence contributing to the promotion of vaccine uptake. We substantiate our findings by making comparative studies of our model on a full lattice and on a randomly diluted one. Our work is expected to provide valuable information for decision-making and design more effective disease-control strategy.

    2008-01-01

    This study is a part of an exploratory study of 50 married and unmarried same-sex couples in Massachusetts conducted by the Wellesley Centers for Women following legalization of same-sex marriage in Massachusetts in 2004. This article examines whether and how legalization of same-sex marriage impacted same-sex partners' commitment to one another, presentation to others as a couple, and treatment as a couple by others. Roughly one-quarter of the couples studied chose not to mark their commitment with ceremonies of any kind, while nearly three-fourths of the couples had either commitment (non-legal) ceremonies, legal weddings, or both. While decisions to legally marry largely were based on gaining legal protections, unforeseen impacts on self and relationships with family, friends, and the larger society revealed multiple layers of meaning. Implications of the study for public policy and social change are discussed.

    The aim of the present study was to analyse the impact of organisational characteristics on the turnover intention of care workers working at nursing homes in Korea. Study participants included 504 care workers working at 14 nursing homes in Korea. The variables measured were: high-performance work practices, consisting of five subfactors (official training, employment stability, autonomy, employee participation and group-based payment); organisational commitment, consisting of three subfactors (affective, normative and continuance commitment); organisational support; and turnover intention. The inter-relationship between high-performance work practices, organisational support, organisational commitment and turnover intention and the fit of the hypothetical model were analysed using structural equation modelling. According to our analysis, high-performance work practices not only had a direct effect on turnover intention, but also an indirect effect by mediating organisational support and commitment. The factor having the largest direct influence on turnover intention was organisational commitment. The results of the present study suggest that to improve health conditions for frail elderly patients at nursing homes, as well as the efficiency of nursing homes through the continuance of nursing service and enhancement of quality of service, long-term care facilities should reduce the turnover intention of care workers by increasing their organisational commitment by actively implementing high-performance work practices.

    Broader Impact plans are required of all NSF proposals. In 2011 the National Science Board, which oversees NSF, reconfirmed NSF's commitment to Broader Impacts in its task force report on the merit review system. At many institutions there are professionals that focus their work on supporting the Broader Impact work of researchers. This session will share the Broader Impacts and Outreach Network for Institutional Collaboration (BIONIC) plan to create a professional network of individuals and offices committed to planning and carrying out effective Broader Impact programming. BIONIC is an NSF Research Coordination Network that is recommended for funding through the Biology Directorate. In this session we will share the goals of BIONIC, and the progress to date in reaching those goals (of which one aspect is the curating of effective Broader Impact initiatives).

    The measurement of tritium in environmental samples requires highest possible sensitivity. In the present study, the authors have optimised the counting window for the analysis of (3)H in environmental samples using the recently installed Ultra Low Level Quantulus 1220 Liquid Scintillation Counting at BARC to improve the detection limit of the system. The optimised counting window corresponding to the highest figure of merit of 883.8 was found to be 20-162 channels. Different brands of packaged drinking waters were analysed to select a blank that would define the system background. The minimum detectable activity (MDA) achieved was 1.5 Bq l(-1) for a total counting time of 500 min. The concentration of tritium in well and bore well water samples collected from the villages of Pune, villages located at 1.8 km from Tarapur Atomic Power Station, Kolhapur and Ratnagiri, was analysed. The activity concentration ranged from 0.55 to 3.66 Bq l(-1). The associated age-dependant dose from water ingestion in the study area was estimated. The effective committed dose recorded for different age classes is negligible compared with World Health Organization and US Environmental Protection Agency dose guidelines.

    This study presents 131I thyroid activity measurements of 56 employees of the Department of Nuclear Medicine and Endocrine Oncology, Centre for Oncology in Gliwice. The research instrument was a whole-body spectrometer. In 44 out of 56 examined staff members, the determined 131I activity was found to be above the detection limit. The measured activities ranged from 6 ± 2 to 457 ± 118 Bq. The maximum estimated committed effective dose reached was 1.5 mSv/y. The results were compared with previous measurements conducted in another Polish nuclear medical unit. From this comparison, we can see that radiological safety among nuclear medicine personnel can be improved by appropriate work organisation. Reducing exposure of workers can be achieved by properly organised turnovers concerning the most vulnerable worksites. In addition, to lower the radiation risk, it is essential to comply strictly with the isolation regime for the patients.

    Physician and nursing shortages in acute and critical care settings require research on factors which might drive their commitment, an important predictor of absenteeism and turnover. However, the degree to which the commitment of a physician or a nurse is driven by individual or organizational characteristics in hospitals remains unclear. In addition, there is a need for a greater understanding of how antecedent-commitment relationships differ between both occupational groups. Based on recent findings in the literature and the results of a pilot study, we investigate the degree to which selected individual and organizational characteristics might enhance an employee's affective commitment working in the field of neonatal intensive care. Moreover, our aim is to examine the different antecedent-commitment relationships across the occupational groups of nurses and physicians. Information about individual factors affecting organizational commitment was derived from self-administered staff questionnaires, while additional information about organizational structures was taken from hospital quality reports and a self-administered survey completed by hospital department heads. Overall, 1486 nurses and 540 physicians from 66 Neonatal Intensive Care Units participated in the study. We used multilevel modeling to account for different levels of analysis. Although organizational characteristics can explain differences in an employee's commitment, the differences can be largely explained by his or her individual characteristics and work experiences. Regarding occupational differences, individual support by leaders and colleagues was shown to influence organizational commitment more strongly in the physicians' group. In contrast, the degree of autonomy in the units and perceived quality of care had a larger impact on the nurses' organizational commitment. With the growing number of hospitals facing an acute shortage of highly-skilled labor, effective strategies on the individual and organizational levels have to be considered to enhance an employee's commitment to his or her organization. Regarding occupational differences in antecedent-commitment relationships, more specific management actions should be undertaken to correspond to different needs and aspirations of nurses and physicians.

    To investigate the relationship between workplace spirituality dimensions and organisational citizenship behaviour (OCB) among nurses through the mediating effect of affective organisational commitment. Nurses' OCB has been considered recently to improve the quality of services to patients and subsequently, their performance. As an influential attitude, affective organisational commitment has been recognized to influence OCB, and ultimately, organisational performance. Meanwhile, workplace spirituality is introduced as a new organisational behaviour concept to increase affective commitment influencing employees' OCB. The cross-sectional study and the respective data were collected with a questionnaire-based survey. The questionnaires were distributed to 305 nurses employed in four public and general Iranian hospitals. To analyse the data, descriptive statistics, Pearson coefficient, simple regression, multiple regression and path analyses were also conducted. The results indicated that workplace spirituality dimensions including meaningful work, a sense of community and an alignment with organisational values have a significant positive relationship with OCB. Moreover, affective organisational commitment mediated the impact of workplace spirituality on OCB. The concept of workplace spirituality through its dimensions predicts nurses' OCB, and affective organisational commitment partially mediated the relationship between workplace spirituality and OCB. Nurses' managers should consider the potentially positive influence of workplace spirituality on OCB and affective commitment among their nurses. With any plan to increase workplace spirituality, the respective managers can improve nurses' performance and would be of considerable importance in the healthcare system. © 2012 Blackwell Publishing Ltd.

    Using the Korean Labor and Income Panel Study (KLIPS), I investigated the impact of family-friendly policies (FFPs) on job satisfaction and organizational commitment in the private sector of South Korea. Paid leave, childcare leave, and support for housing are positively related to both job satisfaction and organizational commitment. Sick leave is positively related to organizational commitment. However, subsidized family event cost is a marginally significant predictor of job satisfaction and organizational commitment. In addition, the relationships between subsidized childcare cost and employee attitudes were not supported. Implications and suggestions for future research are discussed.

    This study examined the effect of different 'doses' of lifelong (>25 years) exercise on arterial stiffening (a hallmark of vascular ageing) in older adults. There are clear dose-dependent effects of lifelong exercise training on human arterial stiffness that vary according to the site and size of the arteries. Similar to what we have observed previously with ventricular stiffening, 4-5 days week -1 of committed exercise over a lifetime are necessary to preserve 'youthful' vascular compliance, especially of the large central arteries. Casual exercise training of two to three times per week may be sufficient for middle-sized arteries like the carotid to minimize arterial stiffening with ageing. However, there is little effect of exercise training on the small-sized peripheral arteries at any dose. Central arterial stiffness increases with sedentary ageing. While near-daily, vigorous lifelong (>25 years) endurance exercise training prevents arterial stiffening with ageing, this rigorous routine of exercise training over a lifetime is impractical for most individuals. The aim was to examine whether a less frequent 'dose' of lifelong exercise training (four to five sessions per week for > 30 min) that is consistent with current physical activity recommendations elicits similar benefits on central arterial stiffening with ageing. A cross-sectional examination of 102 seniors (>60 years old) who had a consistent lifelong exercise history was performed. Subjects were stratified into four groups based on exercise frequency as an index of exercise 'dose': sedentary: fewer than two sessions per week; casual exercisers: two to three sessions per week; committed exercisers: four to five sessions per week; and Masters athletes: six to seven sessions per week plus regular competitions. Detailed measurements of arterial stiffness and left ventricular afterload were collected. Biological aortic age and central pulse wave velocity were younger in committed exercisers and Masters athletes compared to sedentary seniors. Total arterial compliance index (TACi) was lower, while carotid β-stiffness index and effective arterial elastance were higher in sedentary seniors compared to the other groups. There appeared to be a dose-response threshold for carotid β-stiffness index and TACi. Peripheral arterial stiffness was not significantly different among the groups. These data suggest that four to five weekly exercise sessions over a lifetime is associated with reduced central arterial stiffness in the elderly. A less frequent dose of lifelong exercise (two to three sessions per week) is associated with decreased ventricular afterload and peripheral resistance, while peripheral arterial stiffness is unaffected by any dose of exercise. © 2018 The Authors.

  9. How involuntary commitment impacts on the burden of care of the family.

    Little research has examined how, or if, involuntary commitment has impacted on the burden experienced by the family. This paper reports a qualitative study which explored how involuntary commitment under the Mental Health Act (MHA) 2000 in Queensland, Australia impacted on families of people with mental illness. Family members of a person with a mental illness, under involuntary commitment at the time or in the previous 12 months, participated in focus groups. Thematic analysis was used to determine the themes. It was apparent from the views of the family that the use of the involuntary commitment was influenced greatly by the pressures experienced by the mental health services (MHS). The MHA did little to assist the family in gaining access to MHS. It was not until after the family made repeated attempts that they were taken seriously. Often the family had few options other than to use deceit and threats to obtain the necessary treatment required. In view of this, the inherit nature of what involuntary commitment implies for persons under it, such as refusing treatment and management difficulties, indicates the family with such an individual experience more hardship in trying to obtain assistance for that person. Thus, the MHA in Queensland has not met its goals of increasing access to MHS. Family members perceive that they were not being listened to and their concerns were not acted upon. The current culture of the MHS appears to serve, to a large degree, to estrange the family from the consumer making relationships difficult and time-consuming to repair. The mental health profession is urged to consider the culture within their workplace and move towards constructive involvement of the family.

    People within organizations are a key factor for efficiency. Thus employee empowerment has become a popular management strategy. The study aimed to investigate the relationship between psychological empowerment and organizational commitment among medical staff of a hospital in Zahedan city. This cross sectional study was carried out in 2013. A random sample of 172 medical employees in Khatam-ol-Anbia hospital at Zahedan city was selected and responded to items of the questionnaires using a 7-point Likert scale ranging from 1 to 7. For measuring psychological empowerment and organizational commitment, Mishra & Spreitzer's scale and Meyer and Allen's questionnaire were used. A higher score means a higher degree of psychological empowerment or organizational commitment. Analysis was carried out using SPSS. The level of organizational commitment and psychological empowerment significantly were higher than average. There was a significant positive relationship between employees' empowerment and their commitment to organization. Psychological empowerment was a significant predictor of organizational commitment (β = .524). Out of the five dimensions of empowerment three dimensions are significant predictors of commitment and explain 37.1% of the variance in commitment. Due to The positive influence of psychological empowerment on organizational commitment, programs for in-service education should focus on facilitating psychological empowerment to improve and increase organizational commitment. Also, since impact of employees psychological empowerment on organizational commitment partially supported, there are other variables that influence the organizational commitment.

    A nationwide survey was performed assessing current practice of dose data analysis in computed tomography (CT). All radiological departments in Switzerland were asked to participate in the on-line survey composed of 19 questions (16 multiple choice, 3 free text). It consisted of four sections: (1) general information on the department, (2) dose data analysis, (3) use of a dose management software (DMS) and (4) radiation protection activities. In total, 152 out of 241 Swiss radiological departments filled in the whole questionnaire (return rate, 63%). Seventy-nine per cent of the departments (n = 120/152) analyse dose data on a regular basis with considerable heterogeneity in the frequency (1-2 times per year, 45%, n = 54/120; every month, 35%, n = 42/120) and method of analysis. Manual analysis is carried out by 58% (n = 70/120) compared with 42% (n = 50/120) of departments using a DMS. Purchase of a DMS is planned by 43% (n = 30/70) of the departments with manual analysis. Real-time analysis of dose data is performed by 42% (n = 21/50) of the departments with a DMS; however, residents can access the DMS in clinical routine only in 20% (n = 10/50) of the departments. An interdisciplinary dose team, which among other things communicates dose data internally (63%, n = 76/120) and externally, is already implemented in 57% (n = 68/120) departments. Swiss radiological departments are committed to radiation safety. However, there is high heterogeneity among them regarding the frequency and method of dose data analysis as well as the use of DMS and radiation protection activities. • Swiss radiological departments are committed to and interest in radiation safety as proven by a 63% return rate of the survey. • Seventy-nine per cent of departments analyse dose data on a regular basis with differences in the frequency and method of analysis: 42% use a dose management software, while 58% currently perform manual dose data analysis. Of the latter, 43% plan to buy a dose management software. • Currently, only 25% of the departments add radiation exposure data to the final CT report.

    This paper proposes that role stressors decrease helping behavior by undermining employees' normative commitment from a cognitive dissonance perspective and social exchange theory. We also propose two competitive assumptions of the moderating effect of perceived organizational support (POS). In this paper, we first examine these hypotheses in Study 1 and then verify the cognitive dissonance perspective in Study 2. In Study 1, we collected data from 350 employees of two enterprises in China. The results indicated that role stressors had a negative link with helping behavior via the mediating role of normative commitment. The results also showed that POS strengthened the negative relationship between role stressors and normative commitment. In Study 2, we invited 104 employees to participate in a scenario experiment. The results found that role stressors had an impact on normative commitment via dissonance. Our studies verified the combination of cognitive dissonance perspective and social exchange theory to explain the impact of role stressors on helping behavior.

    Background. There are not too many studies that deal with the organizational commitment of emergency physicians. This commitment has been shown to impact organizational performance. The aim of this paper is to analyse the degree of commitment of the emergency physicians in Spanish public hospitals and the factors that may influence it. Method. Online survey using SurveyMonkey to emergency physicians in Spanish public hospitals. Results. Two hundred and five questionnaires were received, 162 from physicians and 43 from heads of the emergency service. Results show an intermediate level of commitment, with affective commitment showing the lowest level and continuance commitment showing the highest level. The capabilities of the physician have an influence on their affective commitment; specific training in emergency procedures and seniority has an influence on their continuance commitment; and the opinion they hold about the organization of their service influences affective commitment. Conclusions. Emergency physicians show an average involvement in the hospital in which they work (average 3.8 on a range of 1 to 5), feel an average affection for it (3.4), and have a high intention to keep working there (4.0). The resources the hospital has due to its level do not have an influence on this commitment, while the training and perceptions of the service do have an influence.

    To explore newly graduated nurses' occupational commitment and its associations with their self-assessed professional competence and other work-related factors. As a factor affecting nurse turnover, newly graduated nurses' occupational commitment and its associations with work-related factors needs exploring to retain adequate workforce. Nurses' commitment has mainly been studied as organisational commitment, but newly graduated nurses' occupational commitment and its association with work-related factors needs further studying. This study used descriptive, cross-sectional, correlation design. A convenience sample of 318 newly graduated nurses in Finland participated responding to an electronic questionnaire. Statistical software, NCSS version 9, was used in data analysis. Frequencies, percentages, ranges, means and standard deviations summarised the data. Multivariate Analyses of Variance estimated associations between occupational commitment and work-related variables. IBM SPSS Amos version 22 estimated the model fit of Occupational Commitment Scale and Nurse Competence Scale. Newly graduated nurses' occupational commitment was good, affective commitment reaching the highest mean score. There was a significant difference between the nurse groups in favour of nurses at higher competence levels in all subscales except in limited alternatives occupational commitment. Multivariate analyses revealed significant associations between subscales of commitment and competence, turnover intentions, job satisfaction, earlier professional education and work sector, competence counting only through affective dimension. The association between occupational commitment and low turnover intentions and satisfaction with nursing occupation was strong. Higher general competence indicated higher overall occupational commitment. Managers' recognition of the influence of all dimensions of occupational commitment in newly graduated nurses' professional development is important. Follow-up studies of newly graduated nurses' commitment, its relationship with quality care, managers' role in enhancing commitment and evaluation of the impact of interventions on improving commitment need further studying. © 2015 John Wiley & Sons Ltd.

    An increased “dose” of endurance exercise training is associated with a greater maximal oxygen uptake (V̇o2max), a larger left ventricular (LV) mass, and improved heart rate and blood pressure control. However, the effect of lifelong exercise dose on metabolic and hemodynamic response during exercise has not been previously examined. We performed a cross-sectional study on 101 (69 men) seniors (60 yr and older) focusing on lifelong exercise frequency as an index of exercise dose. These included 27 who had performed ≤2 exercise sessions/wk (sedentary), 25 who performed 2–3 sessions/wk (casual), 24 who performed 4–5 sessions/wk (committed) and 25 who performed ≥6 sessions/wk plus regular competitions (Masters athletes) over at least the last 25 yr. Oxygen uptake and hemodynamics [cardiac output, stroke volume (SV)] were collected at rest, two levels of steady-state submaximal exercise, and maximal exercise. Doppler ultrasound measures of LV diastolic filling were assessed at rest and during LV loading (saline infusion) to simulate increased LV filling. Body composition, total blood volume, and heart rate recovery after maximal exercise were also examined. V̇o2max increased in a dose-dependent manner (P < 0.05). At maximal exercise, cardiac output and SV were largest in committed exercisers and Masters athletes (P < 0.05), while arteriovenous oxygen difference was greater in all trained groups (P < 0.05). At maximal exercise, effective arterial elastance, an index of ventricular-arterial coupling, was lower in committed exercisers and Masters athletes (P < 0.05). Doppler measures of LV filling were not enhanced at any condition, irrespective of lifelong exercise frequency. These data suggest that performing four or more weekly endurance exercise sessions over a lifetime results in significant gains in V̇o2max, SV, and heart rate regulation during exercise; however, improved SV regulation during exercise is not coupled with favorable effects on LV filling, even when the heart is fully loaded.

    We examined the impact of workplace relationships (perceived organizational support, supervisor-nurse relationships and teamwork) on the engagement, well-being, organizational commitment and turnover intentions of nurses working in Australian and USA hospitals. In a global context of nurse shortages, knowledge about factors impacting nurse retention is urgently sought. We postulated, using the Social Exchange Theory, that nurses' turnover intentions would be affected by several factors and especially their relationships at work. Based on the literature review, data were collected via a self-report survey to test the hypotheses. A self-report survey was used to gather data in 2010-2012 from 510 randomly chosen nurses from Australian hospitals and 718 nurses from US hospitals. A multi-group structural equation modelling analysis identified significant paths and compared the impact between countries. The findings indicate that this model was more effective in predicting the correlations between variables for nurses in Australia compared with the USA. Most paths predicted were confirmed for Australia, except for the impact of teamwork on organizational commitment and turnover, plus the impact of engagement on turnover. In contrast, none of the paths related to supervisor-subordinate relationships was significant for the USA; neither were the paths from teamwork to organizational commitment or turnover. Our findings suggest that well-being is a predictor of turnover intentions, meaning that healthcare managers need to consider nurses' well-being in everyday decision-making, especially in the cost-cutting paradigm that pervades healthcare provision in nearly every country. This is important because nurses are in short supply and this situation will continue to worsen, because many countries have an ageing population. © 2013 John Wiley & Sons Ltd.

    A study dealing with the effects of both organizational culture and mobbing on personal and organizational outcomes of a sample of Spanish emergency workers, is reported here. It was found that there is a strong impact of organizational culture dimensions on mobbing, and that mobbing affects job satisfaction, organizational commitment and organizational citizenship behaviour. Results concerning organizational commitment show that this variable is not a mere effect of mobbing in general, but rather that it is also a direct impact of culture on this outcome.

    This work describes the radiological assessment of the near-surface Maisiagala radioactive waste repository (Lithuania) over the period 2005-2012, with focus on water pathways and special emphasis on tritium. The study includes an assessment of the effect of post-closure upgrading, the durability of which is greater than 30 years. Both human and terrestrial non-human biota are considered, with local low-intensity forestry and small farms being the area of concern. The radiological exposure was evaluated using the RESRAD-OFFSITE, RESRAD-BIOTA and ERICA codes in combination with long-term data from a dedicated environmental monitoring programme. All measurements were performed at the Lithuanian Institute of Physics as part of this project. It is determined that, after repository upgrading, radiological exposure to humans are significantly lower than the human dose constraint of 0.2 mSv/year valid in the Republic of Lithuania. Likewise, for non-human biota, dose rates are below the ERICA/PROTECT screening levels. The potential annual effective inhalation dose that could be incurred by the highest-exposed human individual (which is due to tritiated water vapour airborne release over the most exposed area) does not exceed 0.1 μSv. Tritium-labelled drinking water appears to be the main pathway for human impact, representing about 83 % of the exposure. Annual committed effective dose (CED) values for members of the public consuming birch sap as medical practice are calculated to be several orders of magnitude below the CEDs for the same location associated with drinking of well water. The data presented here indicate that upper soil-layer samples may not provide a good indication of potential exposure to terrestrial deep-rooted trees, as demonstrated by an investigation of stratified (3)H in soil moisture, expressed on a wet soil mass basis, in an area with subsurface contamination.

  6. The impact of intuition and supervisor-nurse relationships on empowerment and affective commitment by generation.

    PubMed

    Farr-Wharton, Rod; Brunetto, Yvonne; Shacklock, Kate

    2012-06-01

      This article reports a generational cohort and leader-member exchange theoretical frameworks-guided study of the influence of the supervisor-subordinate relationship on three generational nurse cohorts' use of intuition, perceptions of empowerment and affective commitment.   Within a global context of nurse shortages, knowledge about factors influencing nurse retention is urgently sought. We postulated that nurses' use of intuition is the key to their empowerment and consequent commitment to the organization, and that impact would vary among the three large nurse generations.   A self-report survey was used to gather data in 2008, which were then analysed using correlations, regression analysis, manova and path analysis. Data were obtained from 900 Baby Boomer and Generations X and Y nurses, randomly chosen from seven private hospitals across Australia.   The findings confirm the important impact of supervisor-nurse relationships upon all three generations' use of intuition. The findings add new knowledge about the differing importance of using intuition for Generation X, Generation Y and Baby Boomer nurses' perceptions of empowerment, suggesting it is more important to Baby Boomers and Generation X than to Generation Y. Further, the impact of using intuition differs significantly among the generational cohorts. The findings suggest the need for a more differentiated tailored style - sensitive to varying needs of the generations. Improving supervisor-nurse relationships is also critical, because of their impact upon nurses' use of intuition, perceptions of empowerment and affective commitment. Poor relationships lead to increased nurse replacement costs. © 2011 Blackwell Publishing Ltd.

  7. Dual or dueling culture and commitment: The impact of a tri-hospital merger.

    PubMed

    Jones, Janice M

    2003-04-01

    This article addresses differences in RNs' commitment to their employing hospital versus the umbrella corporate organization, and the role of organizational culture during a tri-hospital merger. This study is the first to investigate the construct of dual commitment in healthcare organizations. Fiscal restraints, decreasing reimbursement, and increasing competition have made organizational mergers and acquisitions prevalent. As corporate culture changes, organizational variables previously related to organizational commitment may no longer apply. RNs employed on general nursing units at 3 hospitals involved in a merger process completed 2 versions of Mowday's Organizational Commitment Questionnaire. Commitment to hospital and corporate system were examined. Semi-structured interviews, participant observation, and analysis of company documents assessed the organizational culture changes that have occurred. Thirty-one percent of the nurses returned completed questionnaires; 9 were interviewed. RNs from the acquiring hospital demonstrated a significantly stronger commitment to the corporate system than the nurses from the acquired hospitals. The RNs at all 3 hospitals showed significantly greater commitment to their own particular hospital than to the umbrella corporate system. Moderate level of commitment reflected uncertainty of job status, work overload, and feelings of unappreciation. These attitudes prevent nurses from exerting efforts on behalf of the organization.

  8. Psychological and organizational impact of bullying over and above negative affectivity: a survey of two nursing contexts.

    2013-06-01

    Limited research exists on the impact of bullying across psychological and/or organizationally orientated outcomes for nurses working within different nursing contexts. Research that has explored these outcomes has not considered the potential confounding effects of negative affectivity (NA). This study's aim was to examine the extent hospital and aged care nurses are impacted by bullying on these outcomes, while considering NA. A total of 267 hospital nurses/midwives and 168 aged care nurses from an Australian healthcare organization responded to a survey. The results revealed hospital nurses/midwives who experienced bullying reported higher levels of psychological distress, as well as lower commitment and job satisfaction levels. Aged care nurses who experienced bullying reported lower levels of well-being and commitment. NA was a significant covariate for most analyses. Thus, nurses across these contexts are affected by bullying in relation to psychological and organizational-orientated outcomes over and above the effects of NA, particularly for commitment. © 2013 Wiley Publishing Asia Pty Ltd.

    2017-05-01

    The paper presents the theoretical foundations of leadership based on the LMX exchange leader-member theory which essentially involves leadership process where a continuous and creative interaction between leaders and followers is at the centre of attention, during which the leader, among other things, affects the degree of mutual trust and organisational commitment and the quality of relationships in his/her organisation, which actually has a direct impact on organisational performances, effectiveness of the organisation’s business and its market positioning. Also, the paper presents the results of research conducted in organisations in Bosnia and Herzegovina, which undoubtedly point to the fact that the dimensions of leadership based on the LMX exchange leader-member theory, is strongly correlated with the dimensions of mutual trust and organisational commitment, and to have a significant positive impact on them, and therefore on organisational performances and effectiveness of business organisations that were included in this study.

  10. Assessing pediatrics residents' mathematical skills for prescribing medication: a need for improved training.

    To evaluate residents' skills in performing basic mathematical calculations used for prescribing medications to pediatric patients. In 2001, a test of ten questions on basic calculations was given to first-, second-, and third-year residents at Miami Children's Hospital in Florida. Four additional questions were included to obtain the residents' levels of training, specific pediatrics intensive care unit (PICU) experience, and whether or not they routinely double-checked doses and adjusted them for each patient's weight. The test was anonymous and calculators were permitted. The overall score and the score for each resident class were calculated. Twenty-one residents participated. The overall average test score and the mean test score of each resident class was less than 70%. Second-year residents had the highest mean test scores, although there was no significant difference between the classes of residents (p =.745) or relationship between the residents' PICU experiences and their exam scores (p =.766). There was no significant difference between residents' levels of training and whether they double-checked their calculations (p =.633) or considered each patient's weight relative to the dose prescribed (p =.869). Seven residents committed tenfold dosing errors, and one resident committed a 1,000-fold dosing error. Pediatrics residents need to receive additional education in performing the calculations needed to prescribe medications. In addition, residents should be required to demonstrate these necessary mathematical skills before they are allowed to prescribe medications.

    Activity concentrations in food and drink, represented by water and vegetables, have been monitored continuously since the Fukushima Daiichi Nuclear Power Plant accident, with a focus on radioactive cesium. On the other hand, iodine-131 was not measured systematically in the early phase after the accident. The activity concentrations of iodine-131 in food and drink are important to estimate internal exposure due to ingestion pathway. When the internal dose from ingestion in the evacuation areas is estimated, water is considered as the main ingestion pathway. In this study, we estimated the values of activity concentrations in water in the early phase after the accident, using a compartment model as an estimation method. The model uses measurement values of activity concentration and deposition rate of iodine-131 onto the ground, which is calculated from an atmospheric dispersion simulation. The model considers how drinking water would be affected by radionuclides deposited into water. We estimated the activity concentrations of water on Kawamata town and Minamisouma city during March of 2011 and the committed effective doses were 0.08 mSv and 0.06 mSv. We calculated the transfer parameters in the model for estimating the activity concentrations in the areas with a small amount of measurement data. In addition, we estimated the committed effective doses from vegetables using atmospheric dispersion simulation and FARMLAND model in case of eating certain vegetables as option information.

    Clinical development of imatinib in CML established continuous target inhibition as a paradigm for successful tyrosine kinase inhibitor (TKI) therapy. However, recent reports suggested that transient potent target inhibition of BCR-ABL by high-dose TKI (HD-TKI) pulse-exposure is sufficient to irreversibly commit cells to apoptosis. Here, we report a novel mechanism of prolonged intracellular TKI activity upon HD-TKI pulse-exposure (imatinib, dasatinib) in BCR-ABL-positive cells. Comprehensive mechanistic exploration revealed dramatic intracellular accumulation of TKIs which closely correlated with induction of apoptosis. Cells were rescued from apoptosis upon HD-TKI pulse either by repetitive drug wash-out or by overexpression of ABC-family drug transporters. Inhibition of ABCB1 restored sensitivity to HD-TKI pulse-exposure. Thus, our data provide evidence that intracellular drug retention crucially determines biological activity of imatinib and dasatinib. These studies may refine our current thinking on critical requirements of TKI dose and duration of target inhibition for biological activity of TKIs. PMID:22815843

    1987-02-01

    Results of measurements of the whole-body contents of 137Cs during the period 1965-1983 in Lapps from the Kautokeino area in Norway are reported with measurements of 137Cs in reindeer meat during the period 1966-1983. By using available data on 137Cs in precipitation for the period 1950-1980, transfer coefficients from 137Cs in precipitation to reindeer meat have been assessed. A correlation between the 137Cs content in reindeer meat and the 137Cs content in Lapp reindeer breeders has been established. The average whole-body committed dose equivalent, H50, to the reindeer breeders from internally deposited 137Cs from intakes up to year 2000 was assessed to 13 mSv with a peak value of 30 mSv. In comparison, the corresponding committed dose equivalent to the Norwegian population from internally deposited 137Cs has been estimated to be about 1 mSv. The higher intake of 137Cs by reindeer breeders is due to the lichen-reindeer-man exposure pathway.

  2. Organizational commitment as a predictor variable in nursing turnover research: literature review.

    PubMed

    Wagner, Cheryl M

    2007-11-01

    This paper is a report of a literature review to (1) demonstrate the predictability of organizational commitment as a variable, (2) compare organizational commitment and job satisfaction as predictor variables and (3) determine the usefulness of organizational commitment in nursing turnover research. Organizational commitment is not routinely selected as a predictor variable in nursing studies, although the evidence suggests that it is a reliable predictor. Findings from turnover studies can help determine the previous performance of organizational commitment, and be compared to those of studies using the more conventional variable of job satisfaction. Published research studies in English were accessed for the period 1960-2006 using the CINAHL, EBSCOHealthsource Nursing, ERIC, PROQUEST, Journals@OVID, PubMed, PsychINFO, Health and Psychosocial Instruments (HAPI) and COCHRANE library databases and Business Source Premier. The search terms included nursing turnover, organizational commitment or job satisfaction. Only studies reporting mean comparisons, R(2) or beta values related to organizational commitment and turnover or turnover antecedents were included in the review. There were 25 studies in the final data set, with a subset of 23 studies generated to compare the variables of organizational commitment and job satisfaction. Results indicated robust indirect predictability of organizational commitment overall, with greater predictability by organizational commitment vs job satisfaction. Organizational commitment is a useful predictor of turnover in nursing research, and effective as a variable with the most direct impact on antecedents of turnover such as intent to stay. The organizational commitment variable should be routinely employed in nursing turnover research studies.

    2008-04-15

    An assessment of Committed Effective Dose (CED) due to consumption of Red Sea fish containing (210)Po and (137)Cs was performed for 23 different marine fish samples collected from the local market at Port Sudan. The fish were classified according to their feeding habits into three categories: carnivores, herbivores, and omnivores. Measured activity concentrations of (210)Po were found in the ranges 0.25-6.42 (carnivores), 0.7-5 (omnivores) and 1.5-3.8 (herbivores) Bq/kg fresh weight. In the same study, activity concentrations of Cs-137 were determined to be in the ranges 0.1-0.46 (carnivores), 0.09-0.35 (omnivores) and 0.09-0.32 (herbivores) Bq/kg fresh weight, which were several times lower than those of (210)Po. Appropriate conversion factors were used to derive the CED, which was found to be 0.012, 0.01 and 0.01 (microSv/yr) in carnivores, omnivores and herbivores, respectively, for (137)Cs. This contributes about 0.4% of the total dose exclusively by ingestion of fish. For (210)Po, it was found to be 3.47, 4.81 and 4.14 (microSv/yr) in carnivores, omnivores and herbivores, respectively, which represents 99.6% of the total dose (exclusively by ingestion of fish). The results of CED calculations suggest that the dose received by the Sudanese population from the consumption of marine fish is rather small and that the contribution of (137)Cs is negligible compared to (210)Po.

    2018-06-06

    The management of natural environments has become a fundamental issue for companies in recent years. A firm’s environmental commitment affects all levels of its operation. In this study, we investigated whether having an effective and constant relationship with customers over time (customer capital) makes a difference to firms with a high environmental commitment compared with less environmentally committed firms. We found support for our idea by using original survey data from 149 small and medium-sized enterprises (SMEs) in Iran (2016⁻2017). Furthermore, we found that customer capital enhances environmental collaboration with customers which, in turn, has a positive impact on the firm’s environmental commitments. These findings provide empirical evidence for the important role of “getting closer to customers” as a way of enhancing corporate environmental responsibility in developing countries with weak institutional environments.

  12. How commitment and involvement influence the development of strategic consensus in health care organizations: the multidisciplinary approach.

    PubMed

    Carney, Marie

    2007-09-01

    The aim of this study was to describe how clinician and non-clinician managers achieved consensus of strategy in hospitals. This was the first empirical study undertaken that investigated the impact of organizational commitment on the strategic involvement-strategic consensus relationship. Clinicians and non-clinician managers hold a pivotal role in health care management from the strategic perspective. The importance of multidisciplinary collaboration is recognized, yet how strategic consensus is achieved amongst health service managers, has not been previously researched. The focus of the professional is often on local concerns rather on the broader organizational strategy. This orientation has led to the charge by health service management that clinicians are not interested in, or do not seek to be involved in strategy development. As half of the clinician group in this study were registered nurses and midwives it is important, for multidisciplinary and interdisciplinary collaboration and for strategic development that this group has an awareness of the importance of strategic involvement and organizational commitment in the attainment of strategic consensus. A descriptive study was undertaken and quantitative data were generated through the survey method. The aims of the study were articulated through hypotheses. Almost 400 middle manager heads of department, working in acute care not-for-profit health service organizations, in the Republic of Ireland, responded. Findings indicated that a stronger relationship existed between consensus and commitment than between involvement and commitment. In addition, when present in the organization, involvement and commitment together were better predictors of consensus than each of those factors on its own, but significantly commitment had a greater impact in predicting consensus than involvement had.

    2012-07-01

    The purpose of this study was to test a theoretical model linking the impact of expectations on commitment to change and to explore whether change-related communication is a mediating variable between leader-member exchange and expectations. Expectations for change outcomes are an important condition to increase nurses' commitment to change. To understand the role of leadership and communication in expectations development is crucial to promote commitment to change. A predictive, non-experimental design was used in a random sample of 395 nurses. Structural equation modelling was used to analyse the hypothesized model. Positive expectations had a direct effect on affective commitment to change, whereas negative expectation had a direct effect on continuance commitment to change. Leader-member exchange and communication influenced nurse's expectations about change. Communication partially mediated the relationship between Leader-member exchange and expectations. These findings suggested that nurses' expectation about change were strongly linked to commitment to change. Furthermore, the enhancement of communication and relationship with leader contributed to the development of positive and negative expectations. Strategies to promote commitment to change include developing positive expectations about change outcomes and building high-quality leadership style oriented to the communication. © 2011 Blackwell Publishing Ltd.

  14. Professional commitment: Does it buffer or intensify job demands?

    PubMed

    Nesje, Kjersti

    2017-04-01

    The purpose of this study is to investigate whether professional commitment can be seen as a moderator in the relationship between job demands and emotional exhaustion among Norwegian nurses. Inspired by the job demands-resources model, this study explores whether having a strong commitment to the nursing profession can be seen as a resource that buffers the effect of job demands on emotional exhaustion or, conversely, intensifies the impact of job demands. A survey that comprised Norwegian nurses who had graduated three years previously (N = 388) was conducted. Multiple regression was performed to test the hypothesis. The results provide support to a buffering effect; thus, individuals with a higher degree of professional commitment conveyed a weaker association between job demands and emotional exhaustion compared with nurses with a lower degree of commitment. Developing a better understanding of the potential buffering effect of professional commitment is of great interest. The present study is the first to utilize professional commitment as a resource within the job demands-resources framework. © 2017 Scandinavian Psychological Associations and John Wiley & Sons Ltd.

  15. The impact of work rewards on radiographers' organizational commitment.

    PubMed

    Akroyd, D; Mulkey, W; Utley-Smith, Q

    1995-01-01

    Organizational commitment is an affective work outcome that has been used to predict work-related behaviors such as turnover, absenteeism and intent-to-leave. There has been little research in organizational commitment for the allied health professions and no empirical studies in the radiologic sciences. The purpose of this study was to examine the predictive value of selected intrinsic and extrinsic work reward variables--involvement, significance, autonomy, general working conditions, supervision and salary--on staff radiographers' organizational commitment. In this study of 600 full-time staff radiographers in North and South Carolina, supervision (for ages 20-37 years) and involvement (for ages 38-66 years) were significant predictors of organizational commitment. The results of the study indicate that healthcare organizations should provide potential supervisors with managerial training, especially for radiographers who move to supervisory positions based on clinical skills and years of experience. In the long run, such programs are much less expensive than costs associated with replacing employees who leave the organization because of low organizational commitment. Also, management strategies and programs to redesign and enhance job tasks may help maintain or increase organizational commitment.

  16. The impact of ethical climate types on nurses' behaviors in Bosnia and Herzegovina.

    PubMed

    Dinc, M Sait; Huric, Alma

    2017-12-01

    The performance of nurses has become vital in hospitals. Some studies have suggested that nurses' perceptions of the ethical climate in their hospitals are related to higher job satisfaction and organizational commitment and in turn lessen the issue of nursing shortage. (1) The ethical climate types "caring," "independent," "law and code," and "rules" have a significant positive impact on overall job satisfaction. (2) The ethical climate types and overall job satisfaction have significant positive influences on normative and affective and significant negative influences on continuance commitment. The study uses path analysis to understand which types of ethical climate impact overall job satisfaction. It also tries to find the effect of different types of ethical climate and overall job satisfaction on the components of organizational commitment. The relationships between variables were evaluated using factor analysis, reliability, descriptive statistics, correlations, and regression in this study. Participants and research context: A total of 171 useful questionnaires were collected from nurses working in public and private hospitals in Bosnia and Herzegovina. Ethical considerations: Formal research approval was obtained from the administration of each study hospital. Questionnaires with a cover letter were mailed to the hospitals that agreed to participate in the study. In the cover letter, the researchers explained the study purpose, encouraged nurses' voluntary participation, and guaranteed the anonymity of participants. In the first path analyses, "rules" and "caring" climates significantly and positively affected overall job satisfaction. In the second one, while overall job satisfaction and "rules" climate significantly influenced normative commitment, "caring" climate and overall job satisfaction significantly affected affective commitment. The findings of the study have been convenient with the literature. Public and private hospitals can enhance overall job satisfaction and organizational commitment by altering the ethical climate of organizations. Hospital administrations should nurture caring and rule types of ethical climate which influence overall satisfaction. By this way, they could reduce nursing shortage.

    Brief interventions in primary healthcare are cost-effective in reducing drinking problems but poorly implemented in routine practice. Although evidence about implementing brief interventions is growing, knowledge is limited with regard to impact of initial role security and therapeutic commitment on brief intervention implementation. In a cluster randomised factorial trial, 120 primary healthcare units (PHCUs) were randomised to eight groups: care as usual, training and support, financial reimbursement, and the opportunity to refer patients to an internet-based brief intervention (e-BI); paired combinations of these three strategies, and all three strategies combined. To explore the impact of initial role security and therapeutic commitment on implementing brief interventions, we performed multilevel linear regression analyses adapted to the factorial design. Data from 746 providers from 120 PHCUs were included in the analyses. Baseline role security and therapeutic commitment were found not to influence implementation of brief interventions. Furthermore, there were no significant interactions between these characteristics and allocated implementation groups. The extent to which providers changed their brief intervention delivery following experience of different implementation strategies was not determined by their initial attitudes towards alcohol problems. In future research, more attention is needed to unravel the causal relation between practitioners' attitudes, their actual behaviour and care improvement strategies to enhance implementation science.

    There is no global monitoring system for influenza vaccination coverage, making it difficult to assess progress towards the 2003 World Health Assembly (WHA) vaccination coverage target. In 2008, the IFPMA Influenza Vaccine Supply International Task Force (IVS) developed a survey method to assess the global distribution of influenza vaccine doses as a proxy for vaccination coverage rates. The latest dose distribution data for 2014 and 2015 was used to update previous analyses. Data were confidentially collected and aggregated by the IFPMA Secretariat, and combined with previous IFPMA IVS survey data (2004-2013). Data were available from 201 countries over the 2004-2015 period. A "hurdle" rate was defined as the number of doses required to reach 15.9% of the population in 2008. Overall, the number of distributed doses progressively increased between 2004 and 2011, driven by a 150% increase in AMRO, then plateaued. One percent fewer doses were distributed in 2015 than in 2011. Twenty-three countries were above the hurdle rate in 2015, compared to 15 in 2004, but distribution was highly uneven in and across all WHO regions. Three WHO regions (AMRO, EURO and WPRO) accounted for about 95% of doses distributed. But in EURO and WPRO, distribution rates in 2015 were only marginally higher than in 2004, and in EURO there was an overall downward trend in dose distribution. The vast majority of countries cannot meet the 2003WHA coverage targets and are inadequately prepared for a global influenza pandemic. With only 5% of influenza vaccine doses being distributed to 50% of the world's population, there is urgency to redress the gross inequities in disease prevention and in pandemic preparedness. The 2003WHA resolution must be reviewed and revised and a call issued for the renewed commitment of Member States to influenza vaccination coverage targets. Copyright © 2017.

  9. The Impact of Individual and Institutional Factors on Turnover Intent Among Taiwanese Correctional Staff.

    PubMed

    Lai, Yung-Lien

    2017-01-01

    The existing literature on turnover intent among correctional staff conducted in Western societies focuses on the impact of individual-level factors; the possible effects of institutional contexts have been largely overlooked. Moreover, the relationships of various multidimensional conceptualizations of both job satisfaction and organizational commitment to turnover intent are still largely unknown. Using data collected by a self-reported survey of 676 custody staff employed in 22 Taiwanese correctional facilities during April of 2011, the present study expands upon theoretical models developed in Western societies and examines the effects of both individual and institutional factors on turnover intent simultaneously. Results from the use of the hierarchical linear modeling (HLM) statistical method indicate that, at the individual-level, supervisory versus non-supervisory status, job stress, job dangerousness, job satisfaction, and organizational commitment consistently produce a significant association with turnover intent after controlling for personal characteristics. Specifically, three distinct forms of organizational commitment demonstrated an inverse impact on turnover intent. Among institutional-level variables, custody staff who came from a larger facility reported higher likelihood of thinking about quitting their job. © The Author(s) 2015.

  10. The impact of middle manager affective commitment on perceived improvement program implementation success.

    PubMed

    Fryer, Ashley-Kay; Tucker, Anita L; Singer, Sara J

    Recent literature suggests that middle manager affective commitment (emotional attachment, identification, and involvement) to an improvement program may influence implementation success. However, less is known about the interplay between middle manager affective commitment and frontline worker commitment, another important driver of implementation success. We contribute to this research by surveying middle managers who directly manage frontline workers on nursing units. We assess how middle manager affective commitment is related to their perceptions of implementation success and whether their perceptions of frontline worker support mediate this relationship. We also test whether a set of organizational support factors foster middle manager affective commitment. We adapt survey measures of manager affective commitment to our research context of hospitals. We surveyed 67 nurse managers from 19 U.S. hospitals. We use hierarchical linear regression to assess relationships among middle manager affective commitment to their units' falls reduction program and their perceptions of three constructs related to the program: frontline worker support, organizational support, and implementation success. Middle manager affective commitment to their unit's falls reduction program is positively associated with their perception of implementation success. This relationship is mediated by their perception of frontline worker support for the falls program. Moreover, middle managers' affective commitment to their unit's falls program mediates the relationship between perceived organizational support for the program and perceived implementation success. We, through this research, offer an important contribution by providing empirical support of factors that may influence successful implementation of an improvement program: middle manager affective commitment, frontline worker support, and organizational support for an improvement program. Increasing levels of middle manager affective commitment to an improvement program could strengthen program implementation success by facilitating frontline worker support for the program. Furthermore, providing the organizational support items in our survey construct may bolster middle manager affective commitment.

  11. Factors Affecting Organizational Commitment in Navy Corpsmen.

    2017-07-01

    Organizational commitment is a psychological state that has a strong impact on the likelihood that employees will remain with an organization. Among military personnel, organizational commitment is predictive of a number of important outcomes, including reenlistment intentions, job performance, morale, and perceived readiness. Because of the unique challenges and experiences associated with military service, it may be that organizational commitment is even more critical in the military than in civilian populations. Despite the essential role that they play in protecting the health of other service members, little is known about the factors that influence Navy Corpsmen's organizational commitment. This study investigated demographic and psychosocial factors that may be associated with organizational commitment among Corpsmen. Surveys of organizational commitment and possible demographic and psychosocial correlates of organizational commitment were completed by 1,597 male, active duty Navy Corpsmen attending Field Medical Training Battalion-West, Camp Pendleton, California. Bivariate correlations and hierarchical multiple regression analyses were used to determine significant predictors of organizational commitment. Of the 12 demographic and psychosocial factors examined, 6 factors emerged as significant predictors of organizational commitment in the final model: preservice motivation to be a Corpsman, positive perceptions of Corpsman training, confidence regarding promotions, occupational self-efficacy, social support for a Corpsman career, and lower depression. Importantly, a number of the factors that emerged as significant correlates of organizational commitment in this study are potentially modifiable. These factors include confidence regarding promotions, positive perceptions of Corpsman training, and occupational self-efficacy. It is recommended that military leaders and policy-makers take concrete steps to address these factors, thereby strengthening organizational commitment among Corpsmen. Further research is needed to identify ways in which organizational commitment could be strengthened among Corpsmen. Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.

    General practitioners with more positive role security and therapeutic commitment towards patients with hazardous or harmful alcohol consumption are more involved and manage more alcohol-related problems than others. In this study we evaluated the effects of our tailored multi-faceted improvement implementation programme on GPs' role security and therapeutic commitment and, in addition, which professional related factors influenced the impact of the implementation programme. In a cluster randomised controlled trial, 124 GPs from 82 Dutch general practices were randomised to either the intervention or control group. The tailored, multi-faceted programme included combined physician, organisation, and patient directed alcohol-specific implementation strategies to increase role security and therapeutic commitment in GPs. The control group was mailed the national guideline and patients received feedback letters. Questionnaires were completed before and 12 months after start of the programme. We performed linear multilevel regression analysis to evaluate effects of the implementation programme. Participating GPs were predominantly male (63%) and had received very low levels of alcohol related education before start of the study (0.4 h). The programme increased therapeutic commitment (p = 0.005; 95%-CI 0.13 - 0.73) but not role security (p = 0.58; 95%-CI -0.31 - 0.54). How important GPs thought it was to improve their care for problematic alcohol consumption, and the GPs' reported proportion of patients asked about alcohol consumption at baseline, contributed to the effect of the programme on therapeutic commitment. A tailored, multi-faceted programme aimed at improving GP management of patients with hazardous and harmful alcohol consumption improved GPs' therapeutic commitment towards patients with alcohol-related problems, but failed to improve GPs' role security. How important GPs thought it was to improve their care for problematic alcohol consumption, and the GPs' reported proportion of patients asked about alcohol consumption at baseline, both increased the impact of the programme on therapeutic commitment. It might be worthwhile to monitor proceeding of role security and therapeutic commitment throughout the year after the implementation programme, to see whether the programme is effective on short term but faded out on the longer term.

    Large organizations often escalate their commitments to mega-project development, even after evidence becomes available of adverse environmental consequences or lack of economic feasibility. This escalation of commitment transcends both sectorial and national boundaries. Preeminent examples include controversial nuclear projects in the US, hydroelectric projects like the Three Gorges Dam in China, and transport projects like the Chunnel and the Concorde. In this article, the authors examine the experience of Hydro-Quebec with the Great Whale Project. They argue that Hydro-Quebec escalated its commitment even after serious questions emerged about its environmental impacts and economic feasibility, because of (1) its earlier successmore » with large projects, (2) its engineering culture`s norms for consistency, and (3) its role in the government`s desire for economic and cultural autonomy. Finally, they discuss the changes that are necessary to break commitments to such projects.« less

    2014-01-01

    Parent involvement in prevention efforts targeting adolescents increases the impact of such programs. However, the majority of risk-reduction intervention programs that are implemented through schools do not include parents, in part because most existing parental interventions require significant time commitment by parents. We designed a brief parent-adolescent sexual risk communication intervention to be delivered with an effective HIV prevention intervention as part of a randomized, controlled trial among 2564 grade 10 students and their parents in The Bahamas. Mixed effects modeling analysis was conducted to evaluate the effect of the brief parent-adolescent communication intervention using four waves of longitudinal data. Results indicate that a brief parent-adolescent communication intervention is effective in improving parent-adolescent communication on sex-related issues and perceived parental monitoring as well as the youth's condom use skills and self-efficacy. There is a marginal effect on consistent condom use. In addition, there is an apparent dose effect of the brief parent intervention on perceived parent-adolescent sexual risk communication and adolescent outcomes. These findings suggest that adolescent risk reduction interventions should include a brief parent-adolescent communication intervention which should be reinforced by periodic boosters in order to enhance the impact of adolescent HIV prevention programs.

    2009-04-01

    The aim of this study was to examine the influence of empowering work conditions and workplace incivility on nurses' experiences of burnout and important nurse retention factors identified in the literature. A major cause of turnover among nurses is related to unsatisfying workplaces. Recently, there have been numerous anecdotal reports of uncivil behaviour in health care settings. We examined the impact of workplace empowerment, supervisor and coworker incivility, and burnout on three employee retention outcomes: job satisfaction, organizational commitment, and turnover intentions in a sample of 612 Canadian staff nurses. Hierarchical multiple linear regression analyses revealed that empowerment, workplace incivility, and burnout explained significant variance in all three retention factors: job satisfaction (R(2) = 0.46), organizational commitment (R(2) = 0.29) and turnover intentions (R(2) = 0.28). Empowerment, supervisor incivility, and cynicism most strongly predicted job dissatisfaction and low commitment (P < 0.001), whereas emotional exhaustion, cynicism, and supervisor incivility most strongly predicted turnover intentions. In our study, nurses' perceptions of empowerment, supervisor incivility, and cynicism were strongly related to job satisfaction, organizational commitment, and turnover intentions. Managerial strategies that empower nurses for professional practice may be helpful in preventing workplace incivility, and ultimately, burnout.

    Few studies have examined childhood and adolescent animal cruelty motives. Using a sample of 261 inmates surveyed at both medium and maximum security prisons ina southern state, the present study examined the impact of demographic attributes and situational factors relating specifically to a range of animal cruelty motivations. Almost half of the inmates who engaged in animal abuse reported committing some of the acts out of anger, whereas more than a third did so for fun. Regression analyses revealed that the most statistically salient variable in 7 of the 10 motivational models was whether animal cruelty was committed alone. Respondents who reported hurting or killing animals alone were more likely to commit the acts out of anger but less likely to have committed them to impress others, for sex, or to imitate others.

    Since the accident at the Chernobyl Nuclear Power Plant, it has become well known that radiocesium tends to concentrate in wild mushrooms. During the recovery process after the accident at the Fukushima Daiichi Nuclear Power Station (FDNPS), it is important to perform follow-up measurements of the activity concentrations of radiocesium in mushrooms. We evaluated the activity concentrations of the detected artificial radionuclides (radiocesium) in wild mushrooms collected from Kawauchi village, which is within 30 km of the FDNPS, in 2015, four years after the accident. We found that the radiocesium was determined in 147 of 159 mushroom samples (92.4%). Based on the average mushroom consumption of Japanese citizens (6.28 kg per year), we calculated committed effective doses ranging from <0.001 to 0.6 mSv. Although committed effective doses are relatively limited, even if residents have consumed mushrooms several times, continuous monitoring of the radiocesium in mushrooms in Fukushima is needed for sustained recovery from the nuclear disaster.

    The detonation of a radiological dispersion device may result in a situation where individuals inhale radioactive materials and require rapid assessment of internal contamination. The feasibility of using a 2×2-inch sodium-iodide detector to determine the committed effective dose to an individual following acute inhalation of gamma-emitting radionuclides was investigated. Experimental configurations of point sources with a polymethyl methacrylate slab phantom were used to validate Monte Carlo simulations. The validated detector model was used to simulate the responses for four detector positions on six different anthropomorphic phantoms. The nuclides examined included 241Am, 60Co, 137Cs, 131I and 192Ir. Biokinetic modelling was employed to determine the distributed activity in the body as a function of post-inhalation time. The simulation and biokinetic data were used to determine time-dependent count-rate values at optimal detector locations on the body for each radionuclide corresponding to a target committed effective dose (E50) value of 250 mSv.

    Organizational commitment is perceived as an attitude of association to the organization by an employee, which leads to particular job-related behaviors such as work absenteeism, job satisfaction and turnover intensions. Turnover is the ratio of the number of workers that had to be replaced in a given time period to the average number of workers.…

    2011-12-01

    The purpose of this article was to explore the structural relationships among internal marketing, organizational commitment and service quality and to practically apply the findings. Internal marketing is a way to assist hospitals in improving the quality of the services that they provide while executing highly labour-intensive tasks. Through internal marketing, a hospital can enhance the organizational commitment of its employees to attain higher service quality. This research uses a cross-sectional study to survey nursing staff perceptions about internal marketing, organizational commitment and service quality. The results of the survey are evaluated using equation models. The sample includes three regional hospitals in Taiwan. Three hundred and fifty questionnaires were distributed and 288 valid questionnaires were returned, yielding a response rate of 82.3%. The survey process lasted from 1 February to 9 March 2007. The data were analysed with SPSS 12.0, including descriptive statistics based on demographics. In addition, the influence of demographics on internal marketing, organizational commitment and service quality is examined using one-way anova. The findings reveal that internal marketing plays a critical role in explaining employee perceptions of organizational commitment and service quality. Organizational commitment is the mediator between internal marketing and service quality. The results indicate that internal marketing has an impact on both organizational commitment and service quality. Internal marketing should be emphasized to influence frontline nursing staff, thereby helping to create better organizational commitment and service quality. © 2011 The Authors.

    2018-01-01

    Projects are characterized by long working hours, complex tasks and being a kind of temporary organization. As such, work-family conflict is particularly prominent for project employees. This research examined whether and how work-family conflict affects professional commitment among Chinese project professionals. Research hypotheses were developed to explore the relationship between work-family conflict, professional commitment to the project and the mediating effects of perceived organizational support. Data were collected from 327 project managers or professionals working in construction enterprises in China; data were analyzed using structural equation modeling, applying the bootstrapping method. Results showed that there were three dimensions of work-family conflict: time-based conflict, strain-based conflict and behavior-based conflict. There were two dimensions of perceived organizational support: emotional support and instrumental support. The study also tested the negative effect of work-family conflict on professional commitment and the positive effect of perceived organizational support on professional commitment. Specifically, time-based conflict and emotional support had positive effects on professional commitment. Perceived organizational support had a total mediating effect between work-family conflict and professional commitment. The strain-based conflict dimension of work-family conflict had negative impacts on professional commitment through perceived emotional support and instrumental support. Overall, our findings extend a better understanding of work-family conflict and professional commitment in the project setting and verify the importance of social support in balancing work and family and improving employee mobility.

    To assess the predictive ability of various aspects of the work environment for organizational commitment. A questionnaire measuring three dimensions of organizational commitment along with five aspects of work environment and 10 demographic and work setting characteristics was sent to a national, convenience sample of clinical laboratory professionals. All persons obtaining the CLS certification by NCA from January 1, 1997 to December 31, 2006. Only respondents who worked full-time in a clinical laboratory setting were included in the database. Levels of affective, normative, and continuance organizational commitment, organizational support, role clarity, role conflict, transformational leadership behavior of supervisor, and organizational type, total years work experience in clinical laboratories, and educational level of respondents. Questionnaire items used either a 7-point or 5-point Likert response scale. Based on multiple regression analysis for the 427 respondents, organizational support and transformational leadership behavior were found to be significant positive predictors of affective and normative organizational commitment. Work setting (non-hospital laboratory) and total years of work experience in clinical laboratories were found to be significant positive predictors of continuance organizational commitment. Overall the organizational commitment levels for all three dimensions were at the neutral rating or below in the slightly disagree range. The results indicate a less than optimal level of organizational commitment to employers, which were predominantly hospitals, by CLS practitioners. This may result in continuing retention problems for hospital laboratories. The results offer strategies for improving organizational commitment via the significant predictors.

    Radioactivity concentrations of nuclides of the 232 Th and 238 U radioactive chains and 40 K, 90 Sr, 137 Cs, and 239+240 Pu were surveyed for raw and cooked food of the population in the Red River delta region, Vietnam, using α-, γ-spectrometry, and liquid scintillation counting techniques. The concentration of 40 K in the cooked food was the highest compared to those of other radionuclides ranging from (23 ± 5) (rice) to (347 ± 50) Bq kg -1 dw (tofu). The 210 Po concentration in the cooked food ranged from its limit of detection (LOD) of 5 mBq kg -1  dw (rice) to (4.0 ± 1.6) Bq kg -1  dw (marine bivalves). The concentrations of other nuclides of the 232 Th and 238 U chains in the food were low, ranging from LOD of 0.02 Bq kg -1  dw to (1.1 ± 0.3) Bq kg -1  dw. The activity concentrations of 90 Sr, 137 Cs, and 239+240 Pu in the food were minor compared to that of the natural radionuclides. The average annual committed effective dose to adults in the study region was estimated and it ranged from 0.24 to 0.42 mSv a -1 with an average of 0.32 mSv a -1 , out of which rice, leafy vegetable, and tofu contributed up to 16.2%, 24.4%, and 21.3%, respectively. The committed effective doses to adults due to ingestion of regular diet in the Red River delta region, Vietnam are within the range determined in other countries worldwide. This finding suggests that Vietnamese food is safe for human consumption with respect to radiation exposure.

    To explore affective and attitudinal outcomes of aspects of the psychological contract, organizational justice and negative affectivity in nursing. Job satisfaction, mental health and commitment to organizations and the nursing profession is important for nurse retention. The psychological contract and organizational justice are related constructs that have been linked to these outcomes, as has the characteristic of negative affectivity. Rarely have the relationships between these concepts and outcomes been examined. Cross-sectional data were collected during November, 2007. Survey data collected on Registered Nurses and midwives from a large metropolitan hospital in Australia (n = 193, after removing missing cases and outliers) were analysed using structural equation modelling. The model used self-report measures of psychological contract obligations, fulfilment and breach, organizational justice and negative affectivity as predictors of job satisfaction, organizational commitment, career commitment and psychological distress. Goodness-of-fit statistics confirmed a well-fitting model. The model explained 49%, 29%, 60% and 47% of the variance in psychological distress, job satisfaction, organizational commitment and career commitment respectively. Findings support the influence of the psychological contract, fairness and individual differences on outcomes important to nurse retention. Keeping promises is more important than making promises that cannot be kept. The results support a discrepancy mechanism underlying fulfilment and breach. The impact of breach suggests that nurses take breach personally, whereas fulfilment may represent a global evaluation of discrepancies. Ultimately, fulfilling, rather than making promises, keeps nurses happy. © 2013 John Wiley & Sons Ltd.

    2018-01-01

    Commitment devices impose costs on one's future self for failing to follow through on one's intentions, offer no additional benefit to one's future self for following through on the intention, and people voluntarily enroll in them. Enrollment in commitment devices reflects self-awareness that one may lack sufficient self-control to fulfill one's intentions. There is little experimental research on whether school-age children possess the self-awareness necessary to enroll in a commitment device, despite evidence that children and young adolescents have many positive intentions that they fail to live up to, such as demonstrating improved school conduct or eating healthier. We report the first field experiment examining the demand for, and impact of, commitment devices among middle school students. We offered students a commitment device that imposed future costs for failing to improve in-school conduct. When presented with the opportunity to actively opt-in (default not enrolled), over one-third of students elected to enroll. When presented with the opportunity to actively opt-out (default enrolled), more than half elected to remain enrolled, showing that changing default options can increase commitment device enrollment. Despite demand for the self-control strategy, taking-up the commitment device did not affect student behavior. These findings have implications for youth-based behavioral interventions broadly, as well as those focused on eating behaviors. PMID:29541040

  4. The Impact of Trust on Organization Commitment

    As the global economy continues to spawn competitive forces, organizations have sought to become more competitive by cutting costs, eliminating non-value added work, and using more automation. Jobs have become broader and more flexible leading to a leaner workforce with higher-level knowledge and skills and more responsibility for day-to-day decisions. More than ever, organizations depend on employees as the innovators and designers of products and processes and as a source of strategic advantage. Therefore employee commitment among knowledge workers is needed to maintain organizational viability. It would seem that stronger relationships due to greater dependency, involvement, and investment would develop between employers and high-technology workers resulting in more committed employees. However, the opposite has been evidenced as key knowledge workers are changing jobs frequently. This may be due to a perceived lack of commitment by management to its employees. The notion of exchange may dominate the development of organizational commitment whereby an individual decides what to give a firm (commitment, extra effort, better performance, etc.) based on what the firm gives them (e.g., trust and security). It is the relationship between an employee's organizational commitment and the responding level of trust in the organization that is examined in this paper. An experiment is described that will seek to identify this relationship. Preliminary results are expected to show a positive relationship whereby employee commitment is positively correlated with organizational trust.

    This study aims to investigate the relationships between workplace spirituality, organizational citizenship behavior (OCB), and affective organizational commitment among nurses, and whether affective commitment mediates the relationship between workplace spirituality and OCB. In the present correlational study, a cross-sectional design was employed, and data were collected using a questionnaire-based survey. Based on the random sampling, 305 nurses were chosen and questionnaires were distributed among respondents in four public and general hospitals located in Kerman, Iran. To analyze the data descriptive statistics, Pearson coefficient, simple and multiple regression, and path analyses were also conducted. Workplace spirituality has a positive influence on nurses' OCB and affective commitment. Workplace spirituality explained 16% of the variation in OCB, while it explained 35% of the variation in affective commitment among nurses. Moreover, affective organizational commitment mediated the impact of workplace spirituality on OCB. Workplace spirituality predicts nurses' OCB and affective organizational commitment. It emphasizes benefits from the new perspective of workplace spirituality, particularly among nurses who need to be motivated in their work. This study illustrates that there are potential benefits owing to the positive influence of workplace spirituality on OCB and affective commitment among nurses. Managers of nursing services should consider workplace spirituality and its positive influence on nurses' outcomes in order to improve their performance and, subsequently, the healthcare system. © 2012 Sigma Theta Tau International.

Clinic-level cluster-randomized trial with 4 arms: individual, group, or combined incentives, and control. A total of 83 full-time primary care physicians at 12 Veterans Affairs medical centers completed web-based surveys measuring their goal commitment to guideline-recommended hypertension care every 4 months and telephone interviews at months 8 and 16. Intervention arm participants received performance-based incentives every 4 months for 5 periods. All participants received guideline education at baseline and audit and feedback every 4 months. Physician goal commitment did not vary over time or across arms. Participants reported patient nonadherence was a perceived barrier and consistent follow-up was a perceived facilitator to successful hypertension care, suggesting that providers may perceive hypertension management as more of a patient responsibility (external locus of control). Financial incentives may constitute an insufficiently strong intervention to influence goal commitment when providers attribute performance to external forces beyond their control.

    2018-01-01

    Introduction: The Council Directive 2013/59 Euratom has a clear commitment for keeping medical radiation exposure as low as reasonably achievable and demands a regular review and use of diagnostic reference levels. Methods: In dental implantology, the range of effective doses for cone beam computed tomography (CBCT) shows a broad overlap with multislice computed tomography (MSCT). More recently, ultralow dose imaging with new generations of MSCT scanners may impart radiation doses equal to or lower than CBCT. Dose reductions in MSCT have been further facilitated by the introduction of iterative image reconstruction technology (IRT), which provides substantial noise reduction over the current standard of filtered backward projection (FBP). Aim: The aim of this article is to review the available literature on ultralow dose CT imaging and IRTs in dental implantology imaging and to summarize their influence on spatial and contrast resolution, image noise, tissue density measurements, and validity of linear measurements of the jaws. Conclusion: Application of ultralow dose MSCT with IRT technology in dental implantology offers the potential for very large dose reductions compared with standard dose imaging. Yet, evaluation of various diagnostic tasks related to dental implantology is still needed to confirm the results obtained with various IRTs and ultra-low doses so far. PMID:29492174

    A large health maintenance organization (HMO) in San Diego, California developed a year-long communication plan to increase employee knowledge of the company's strategic goals and enhance organizational commitment. Survey results indicated: Respondents remembered significantly more strategic goals after program implementation. Respondents who had personal involvement in achieving goals remembered significantly more goals than those without involvement. Department meetings and the employee/physician newsletter were identified as primary sources for learning about goals. These findings suggest that organizations may be able to strengthen employee commitment by increasing awareness of the organization's strategic goals and encouraging employees to become personally involved in the achievement of those goals.

    The main purpose of this study was to investigate the impact of perceived HR practices on affective commitment and turnover intention. This study explored which HR practices were relatively more important in predicting affective commitment and turnover intention. A total of 302 employees from the United States and 317 from South Korea completed the same questionnaires for assessing the aforementioned relationships. The results illustrated that among perceived HR practices, internal mobility had the most significant association with turnover intention in both the United States and South Korea. While internal mobility was a stronger predictor of affective commitment for the United States sample, training was the most important variable for predicting affective commitment in South Korea. The second purpose of the study was to examine whether individuals’ positive affect influences the relationship between perceived HR practices and affective commitment and turnover intention. In the United States, positive affect moderated the relationship between perceived HR practices and affective commitment and turnover intention such that the relationships were stronger for individuals reporting high positive affect relative to those reporting low positive affect. However, these relationships were not significant in South Korea. We discuss the implications of these results, study limitations, and practical suggestions for future research. PMID:29867647

    The potential for significant uranium exposure in gaseous diffusion plants is very low. The potential for significant radiation exposure in uranium hexafluoride manufacturing is very real. Exposures can be controlled to low levels only through the cooperation and commitment of facility management and operating personnel. Exposure control can be adequately monitored by a combination of air analyses, urinalyses, and measurements of internal deposition as obtained by the IVRML. A program based on control of air-borne uranium exposure has maintained the internal dose of the Paducah Gaseous Diffusion Plant workman to less than one-half the RPG dose to the lung (15more » rem/year) and probably to less than one-fourth that dose.

  14. Further evaluations of the toxicity of irradiated advanced heavy water reactor fuels.

    2014-11-01

    The neutron economy and online refueling capability of heavy water moderated reactors enable them to use many different fuel types, such as low enriched uranium, plutonium mixed with uranium, or plutonium and/or U mixed with thorium, in addition to their traditional natural uranium fuel. However, the toxicity and radiological protection methods for fuels other than natural uranium are not well established. A previous paper by the current authors compared the composition and toxicity of irradiated natural uranium to that of three potential advanced heavy water fuels not containing plutonium, and this work uses the same method to compare irradiated natural uranium to three other fuels that do contain plutonium in their initial composition. All three of the new fuels are assumed to incorporate plutonium isotopes characteristic of those that would be recovered from light water reactor fuel via reprocessing. The first fuel investigated is a homogeneous thorium-plutonium fuel designed for a once-through fuel cycle without reprocessing. The second fuel is a heterogeneous thorium-plutonium-U bundle, with graded enrichments of U in different parts of a single fuel assembly. This fuel is assumed to be part of a recycling scenario in which U from previously irradiated fuel is recovered. The third fuel is one in which plutonium and Am are mixed with natural uranium. Each of these fuels, because of the presence of plutonium in the initial composition, is determined to be considerably more radiotoxic than is standard natural uranium. Canadian nuclear safety regulations require that techniques be available for the measurement of 1 mSv of committed effective dose after exposure to irradiated fuel. For natural uranium fuel, the isotope Pu is a significant contributor to the committed effective dose after exposure, and thermal ionization mass spectrometry is sensitive enough that the amount of Pu excreted in urine is sufficient to estimate internal doses, from all isotopes, as low as 1 mSv. In addition, if this method is extended so that Pu is also measured, then the combined amount of Pu and Pu is sufficiently high in the thorium-plutonium fuel that a committed effective dose of 1 mSv would be measurable. However, the fraction of Pu and Pu in the other two fuels is sufficiently low that a 1 mSv dose would remain below the detection limit using this technique. Thus new methods, such as fecal measurements of Pu (or other alpha emitters), will be required to measure exposure to these new fuels.

    It is not yet known whether hematopoietic stem and progenitor cells (HSPCs) are compromised in the aging population of atomic bomb (A-bomb) survivors after their exposure nearly 70 years ago. To address this, we evaluated age- and radiation-related changes in different subtypes of circulating HSPCs among the CD34-positive/lineage marker-negative (CD34(+)Lin(-)) cell population in 231 Hiroshima A-bomb survivors. We enumerated functional HSPC subtypes, including: cobblestone area-forming cells; long-term culture-initiating cells; erythroid burst-forming units; granulocyte and macrophage colony-forming units; and T-cell and natural killer cell progenitors using cell culture. We obtained the count of each HSPC subtype per unit volume of blood and the proportion of each HSPC subtype in CD34(+)Lin(-) cells to represent the lineage commitment trend. Multivariate analyses, using sex, age and radiation dose as variables, showed significantly decreased counts with age in the total CD34(+)Lin(-) cell population and all HSPC subtypes. As for the proportion, only T-cell progenitors decreased significantly with age, suggesting that the commitment to the T-cell lineage in HSPCs continuously declines with age throughout the lifetime. However, neither the CD34(+)Lin(-) cell population, nor HSPC subtypes showed significant radiation-induced dose-dependent changes in counts or proportions. Moreover, the correlations of the proportions among HSPC subtypes in the survivors properly revealed the hierarchy of lineage commitments. Taken together, our findings suggest that many years after exposure to radiation and with advancing age, the number and function of HSPCs in living survivors as a whole may have recovered to normal levels.

The authors reviewed various components and procedures of this approach and discussed some practical aspects of its application using as an example of a study evaluating a presentation on menopausal care for primary care physicians. The CTC approach is a valuable evaluation tool, but it requires supplementation with other data to have a complete picture of the impact of education on practice. From the evaluation perspective, the self-reported nature of the CTC data is a major limitation of this method. PMID:20457715

  19. An empirical examination of the effects of family commitment in education on student achievement in seventh grade science

    Wang, Jianjun; Wildman, Louis

    A national data base from the Longitudinal Study of American Youth (LSAY) was employed to examine the effects of family commitment in education on student achievement in seventh grade science. The backward elimination procedure in the Statistical Analysis System (SAS) was adopted in this study to select significant variables of family commitment at = .05. The results show that around 22% of the variance in student science achievement can be explained by the selected significant LSAY variables. An analysis of the impact of family commitment seems to indicate that parental education and encouragement are important factors in the improvement of student achievement. However, educators, including school personnel and parents, should exercise caution regarding how they help students with their homework and how they reward students for good grades.Received: 14 June 1994; Revised: 31 October 1994;

    This paper investigates the determinants of nations' commitment to environmental protection at the international level by focusing on the role of national intelligence and the level of democracy. The national intelligence is measured by nation's IQ scores. The findings based on a sample of 152 nations provide strong evidence that intelligence has statistically significant impact on ratification of international environmental agreements, and the countries with IQ 10-points above global average are 23% more likely to sign multilateral environmental agreements than others. The findings also demonstrate that it is the combination of high-level of intelligence of nations and democracy, that likely result in international environmental commitments.

    The purpose of this paper is to examine the impact of demographic variables, organizational commitment levels, perception of health and quality of work on turnover intentions. A self-reported cross-sectional survey design was used to collect data from Jordanian registered nurses who were working between June 2011 and November 2011. The findings showed strong effects of the quality of work, perception of health and normative organizational commitments on turnover intentions. This study sheds the light on the important work outcomes in health-care organizations. Increasing nursing quality of work and normative organizational commitment are good strategies for reducing turnover intentions. © 2013 Wiley Publishing Asia Pty Ltd.

    Aim To investigate an impact of various biological, psychological and social factors on perpetration of criminal offences by persons with mental disorders and to examine legal requirements for placement of persons with mental disorders, who committed criminal offences. Methods This retrospective, descriptive study based on the analysis of data collected from records of the Zenica Penitentiary, Forensic Department (age, qualifications, employment status, marital status, mental disorders, information related to earlier treatments, type of committed criminal offense, duration of the security measure of mandatory psychiatric treatment and custody) included 154 examinees. Results The study included 154 male examinees. An average age of the examinees was 34 years. An average duration spent at the Forensic Department was 3 years, murder was committed by 68 (44.15%) examinees, and 34 (22.07%) examinees committed attempted murder. Eighty-five (55. 19 %) examinees suffered from schizophrenia, 30 (19.48%) had delusional disorder, and 19 (12.33%) had mental retardation. Conclusion The highest number of committed crimes was in correlation with schizophrenia, (the highest number of examinees suffered from schizophrenia). It is necessary to work on the establishment of a forensic hospital in the territory of the Federation of Bosnia and Herzegovina in order to create good conditions for rehabilitation of patients with mental disorders who committed criminal offences.

    The main element to build a leading university requires lecturer commitment in a professional manner. Commitment is measured through willpower, loyalty, pride, loyalty, and integrity as a professional lecturer. A total of 135 from 337 university lecturers were sampled to collect data. Data were analyzed using validity and reliability test and multiple linear regression. Many studies have found a link on the commitment of lecturers, but the basic cause of the causal relationship is generally neglected. These results indicate that the professional commitment of lecturers affected by variables empowerment, academic culture, and trust. The relationship model between variables is composed of three substructures. The first substructure consists of endogenous variables professional commitment and exogenous three variables, namely the academic culture, empowerment and trust, as well as residue variable ɛ y . The second substructure consists of one endogenous variable that is trust and two exogenous variables, namely empowerment and academic culture and the residue variable ɛ 3. The third substructure consists of one endogenous variable, namely the academic culture and exogenous variables, namely empowerment as well as residue variable ɛ 2. Multiple linear regression was used in the path model for each substructure. The results showed that the hypothesis has been proved and these findings provide empirical evidence that increasing the variables will have an impact on increasing the professional commitment of the lecturers.

  4. Committed warming inferred from observations

    Due to the lifetime of CO2, the thermal inertia of the oceans, and the temporary impacts of short-lived aerosols and reactive greenhouse gases, the Earth’s climate is not equilibrated with anthropogenic forcing. As a result, even if fossil-fuel emissions were to suddenly cease, some level of committed warming is expected due to past emissions as studied previously using climate models. Here, we provide an observational-based quantification of this committed warming using the instrument record of global-mean warming, recently improved estimates of Earth’s energy imbalance, and estimates of radiative forcing from the Fifth Assessment Report of the Intergovernmental Panel on Climate Change. Compared with pre-industrial levels, we find a committed warming of 1.5 K (0.9-3.6, 5th-95th percentile) at equilibrium, and of 1.3 K (0.9-2.3) within this century. However, when assuming that ocean carbon uptake cancels remnant greenhouse gas-induced warming on centennial timescales, committed warming is reduced to 1.1 K (0.7-1.8). In the latter case there is a 13% risk that committed warming already exceeds the 1.5 K target set in Paris. Regular updates of these observationally constrained committed warming estimates, although simplistic, can provide transparent guidance as uncertainty regarding transient climate sensitivity inevitably narrows and the understanding of the limitations of the framework is advanced.

    In the case of accidental release of Uranium-238 (238U) radionuclides in a nuclear facility or in the environment, internal contamination by either acute or chronic exposure has the potential to induce both radiological and chemical toxic effects. A study was conducted to estimate the 238U radionuclide concentration in the long beans using Induced Coupled Mass Plasma-Spectrometry (ICP-MS). 238U radionuclide is a naturally occurring radioactive material that can be found in soil and can be transferred to the long bean (Vigna unguiculata subsp. Sesquapedalis) directly or indirectly via water or air. Kidney and liver are the major sites of deposition of 238U radionuclide. The obtained dose exposed in the liver and kidney is used to assess the safety level for public intake of 238U radionuclide from the consumption of long beans. The concentration of 238U radionuclide measured in long bean samples was 0.0226 ± 0.0009 mg/kg. Total activity of 238U radionuclide was 0.0044 ± 0.0002 Bq/day with the daily intake of 0.3545 ± 0.0143 µg/day and the annual committed effective dose due to ingestion of 238U radionuclide in long beans was 0.2230 ± 0.0087 µSv/year. The committed equivalent dose of 238U radionuclide from the assessment in the liver and kidney are 0.4198 ± 0.0165 nSv and 10.9335 ± 0.4288 nSv. The risk of cancer of 238U radionuclide was determined to be (86.0466 ± 3.3748) × 10-9. Thus, the results concluded that 238U radionuclide in local long beans was in the permitted level and safe to consume without posing any significant radiological threat to population.

    2011-03-01

    According to the 2007 Taiwan Labor Front Human Resources Report, as much as 47.6% of nurses at some public hospitals were contracted rather than full time. Furthermore, turnover rates for contract nurses were found to be as high as five to eight times of those for full-time nurses. Because high turnover rates are likely to induce negative impacts on the stability of care provided in the absence of staffing continuity, the association between nursing employment arrangement and nursing care quality is attracting greater attention. This study was designed to investigate the work status of contract versus full-time nurses at a public hospital in Taiwan and to examine the impact of such on work-related attitudes, organizational citizenship behavior, and job performance. Samples were recruited from a public hospital in Taiwan. In addition to self-rated items, researchers used supervisor-rated structured questionnaires for job performance to attenuate the possible effect of common method bias. The study investigated the impact of hospital nurse employment status on work-related attitudes, organizational citizenship behavior, and job performance using a regression model that included the critical work-related attitudes variables of job satisfaction and organizational commitment. Study findings included the following: (a) organizational commitment, job satisfaction, organizational citizenship behavior, and job performance correlate positively with one another. (b) No significant difference between contract and full-time nurses was found in terms of organizational commitment, job satisfaction, organizational citizenship behavior, and self-rated job performance. However, when rated by supervisors, reported job performance levels for full-time nurses were significantly higher than those of contract nurses. (c) Organizational citizenship behavior exhibited a mediating effect between job satisfaction, organizational commitment, and job performance. In this study, supervisors gave higher job performance ratings to full-time nurses than to contract nurses. This result deserves further investigation.

    As concern about youth obesity continues to mount, there is increasing consideration of widespread policy changes to support improved nutritional and enhanced physical activity offerings in schools. A critical element in the success of such programs may be to involve students as spokespeople for the program. Making such a public commitment to healthy lifestyle program targets (improved nutrition and enhanced physical activity) may potentiate healthy behavior changes among such students and provide a model for their peers. This paper examines whether student's "public commitment"--voluntary participation as a peer communicator or in student-generated media opportunities--in a school-based intervention to prevent diabetes and reduce obesity predicted improved study outcomes including reduced obesity and improved health behaviors. Secondary analysis of data from a 3-year randomized controlled trial conducted in 42 middle schools examining the impact of a multi-component school-based program on body mass index (BMI) and student health behaviors. A total of 4603 students were assessed at the beginning of sixth grade and the end of eighth grade. Process evaluation data were collected throughout the course of the intervention. All analyses were adjusted for students' baseline values. For this paper, the students in the schools randomized to receive the intervention were further divided into two groups: those who participated in public commitment activities and those who did not. Students from comparable schools randomized to the assessment condition constituted the control group. We found a lower percentage of obesity (greater than or equal to the 95th percentile for BMI) at the end of the study among the group participating in public commitment activities compared to the control group (21.5% vs. 26.6%, p = 0.02). The difference in obesity rates at the end of the study was even greater among the subgroup of students who were overweight or obese at baseline; 44.6% for the "public commitment" group, versus 53.2% for the control group (p = 0.01). There was no difference in obesity rates between the group not participating in public commitment activities and the control group (26.4% vs. 26.6%). Participating in public commitment activities during the HEALTHY study may have potentiated the changes promoted by the behavioral, nutrition, and physical activity intervention components.

    It is useful to assess annual effective doses less than 100 mSv. Beyond the''score-keeping'' needs of regulatory compliance, there are at least seven other valid reasons for performing personnel monitoring, many of which fall into the category of''no news is good news,'' or more aptly,''null news, as long as you can prove it, is good news.'' These are performance measures for contractual compliance, diagnosis of problems with radiation protection programs, health surveillance and occupational epidemiology, prevention of and support for litigation, demonstration of management commitment and safety, worker counseling, ensuring peace of mind. Furthermore, it is shown that there ismore » very reasonable expectation that detriment may be associated with doses smaller than 100 mSv per year.« less

    Purpose: This report describes the value of a voluntary error reporting system and the impact of a series of quality assurance (QA) measures including checklists and timeouts on reported error rates in patients receiving radiation therapy. Methods and Materials: A voluntary error reporting system was instituted with the goal of recording errors, analyzing their clinical impact, and guiding the implementation of targeted QA measures. In response to errors committed in relation to treatment of the wrong patient, wrong treatment site, and wrong dose, a novel initiative involving the use of checklists and timeouts for all staff was implemented. The impactmore » of these and other QA initiatives was analyzed. Results: From 2001 to 2011, a total of 256 errors in 139 patients after 284,810 external radiation treatments (0.09% per treatment) were recorded in our voluntary error database. The incidence of errors related to patient/tumor site, treatment planning/data transfer, and patient setup/treatment delivery was 9%, 40.2%, and 50.8%, respectively. The compliance rate for the checklists and timeouts initiative was 97% (P<.001). These and other QA measures resulted in a significant reduction in many categories of errors. The introduction of checklists and timeouts has been successful in eliminating errors related to wrong patient, wrong site, and wrong dose. Conclusions: A comprehensive QA program that regularly monitors staff compliance together with a robust voluntary error reporting system can reduce or eliminate errors that could result in serious patient injury. We recommend the adoption of these relatively simple QA initiatives including the use of checklists and timeouts for all staff to improve the safety of patients undergoing radiation therapy in the modern era.« less

    The purpose of this paper is to examine the relationship between the quality management practices (QMPs) and organisational performance for the manufacturing industry in Malaysia. In this study, a QMPs and organisational performance framework is developed according to a comprehensive literature review which cover aspects of hard and soft quality factors in manufacturing process environment. A total of 11 hypotheses have been put forward to test the relationship amongst the six constructs, which are management commitment, training, process management, quality tools, continuous improvement and organisational performance. The model is analysed using Structural Equation Modeling (SEM) with AMOS software version 18.0 using Maximum Likelihood (ML) estimation. A total of 480 questionnaires were distributed, and 210 questionnaires were valid for analysis. The results of the modeling analysis using ML estimation indicate that the fits statistics of QMPs and organisational performance model for manufacturing industry is admissible. From the results, it found that the management commitment have significant impact on the training and process management. Similarly, the training had significant effect to the quality tools, process management and continuous improvement. Furthermore, the quality tools have significant influence on the process management and continuous improvement. Likewise, the process management also has a significant impact to the continuous improvement. In addition the continuous improvement has significant influence the organisational performance. However, the results of the study also found that there is no significant relationship between management commitment and quality tools, and between the management commitment and continuous improvement. The results of the study can be used by managers to prioritize the implementation of QMPs. For instances, those practices that are found to have positive impact on organisational performance can be recommended to managers so that they can allocate resources to improve these practices to get better performance.

    Despite strong evidence confirming vaccination is safe and effective, some parents choose not to vaccinate their children. In 2016, the Australian Government introduced legislation strengthening links between vaccination compliance and some government payments. We interviewed thirty-one non-vaccinating parents about the impacts of this policy. Data analysis produced three key themes: 'questioning policy integrity', 'minimising impact' and 'holding my ground'. Affected parents offset reduced income by removing children from early childhood learning, reducing work commitments, moving residence to reduce living costs and accessing informal childcare arrangements. Parents reported a greater commitment to their decision not to vaccinate and an increased desire to maintain control over health choices for their children including an unprecedented willingness to become involved in protest action. Our study identifies why financial penalties have not been an effective policy measure for this sample of non-vaccinating parents, an understanding which may assist in the development of future legislation.

  14. Fulfill Promises and Avoid Breaches to Retain Satisfied, Committed Nurses.

    2016-07-01

    This study examines two commonly proposed mechanisms, violation and trust, to see if they mediate the relationships between the components of the psychological contract (i.e., promises, fulfillment, and breach) and their impact on the work-related outcomes of job satisfaction, intent to quit, and organizational commitment. Online surveys were completed by 459 Australian nurses. Structural equation modeling revealed that breach and fulfillment have direct and mediated effects on the outcomes, whereas promises had no impact. Violation partially mediated the relationship between breach and job satisfaction and intent to quit, while trust partially mediated the relationships between fulfillment and organizational commitment, and breach and organizational commitment. Negative experiences (i.e., breaches) were related to both increased feelings of violation and decreased feelings of trust. In contrast, positive experiences (i.e., fulfillment) increased trust but did not significantly reduce feelings of violation. Nurse and organizational managers can use these findings to improve communication with nurses so as to minimize the negative effects of breach and maximize the positive effects of fulfillment and thus improve attitudes. Nurse managers need to be careful to make promises regarding their nurses' employment that they can fulfill and to particularly avoid breaking the psychological contract. The potentially disproportionate negative effect of breach means that a breach can undo a lot of efforts to fulfill employment-related promises. © 2016 Sigma Theta Tau International.

    In this article, some information about the data used in the article and a citation were not included. The details of the corrections are provided.] This study uses 3-level, 2-wave time-lagged data from a random sample of 55 high-technology firms, 238 teams, and 1,059 individuals in China to investigate a multilevel combinational model of employee creativity. First, we hypothesize that firm (macrolevel) high-commitment work systems are conducive to individual (microlevel) creativity. Furthermore, we hypothesize that this positive crosslevel main impact may be combined with middle-level (mesolevel) factors, including team cohesion and team task complexity, such that the positive impact of firm high-commitment work systems on individual creativity is stronger when team cohesion is high and the team task more complex. The findings from random coefficient modeling analyses provide support for our hypotheses. These sets of results offer novel insight into how firms can use macrolevel and mesolevel contextual variables in a systematic manner to promote employee creativity in the workplace, despite its complex nature.

    2015-01-01

    Despite the potentially severe consequences that could result, there is a paucity of research on organizational cynicism within US healthcare providers. In response, this study investigated the effect of cynicism on organizational commitment, job satisfaction, and interest in leaving the hospital for another job in a sample of 205 physicians and 842 nurses. Three types of cynicism were investigated: trait (dispositional), global (directed toward the hospital), and local (directed toward a specific unit or department). Findings indicate that all three types of cynicism were negatively related to affective organizational commitment and job satisfaction, but positively related to interest in leaving. In both nurse and physician samples, cynicism explained about half of the variance in job satisfaction and affective commitment, which is the type of commitment managers are most eager to promote. Cynicism accounted for about a quarter and a third of the variance in interest in leaving the hospital for nurses and physicians, respectively. Trait, global and local cynicism each accounted for unique variance in affective commitment, satisfaction, and interest in leaving, with global cynicism exerting the largest influence on each outcome. The implications for managers are that activities aimed at decreasing organizational cynicism are likely to increase affective organizational commitment, job satisfaction, and organizational tenure.

    Using the agar culture technique, we have measured the effect of granulocyte extracts GCE (and of erythrocyte-RCE and lymph node extracts-LNE) on the growth and proliferation of the committed granulocytic precursor cells, CFU-C. In addition we have determined their effects on the proliferation of the developing colony cells and on the ultimate cell production in the colonies. The results show that GCE has no effect on the growth or proliferative activity on the CFU-C. It does, however, reduce both the autoradiographic labelling indices of the developing colony cells and the net colony cellularities, acting as a cell cycle modulator. These are effects specific to the GCE since at the dose levels used, neither RCE nor LNE affected these measurements.

    This work examines the aggregation of justice perceptions to the departmental level and the business-unit level, the impact of these aggregate perceptions on business-unit-level outcomes, and the usefulness of the distinction between procedural and interpersonal justice at different levels of analysis. Latent variables analyses of individual-level and department-level data from 4,539 employees in 783 departments at 97 hotel properties showed that the 2 justice types exercise unique paths of impact on employees' organizational commitment and thus on turnover intentions and discretionary service behavior. Business-unit-level analyses further demonstrate paths of association between aggregate justice perceptions, aggregate commitment levels, and the business-unit-level outcomes of employee turnover rates and customer satisfaction ratings.

    Use of antidepressant medications has been linked to detrimental impacts on bone mineral density and osteoporosis; however, the cellular basis behind these observations remains poorly understood. The effect does not appear to be homogeneous across the whole class of drugs and may be linked to affinity for the serotonin transporter system. In this study, we hypothesized that antidepressants have a class- and dose-dependent effect on mesenchymal stem cell (MSC) differentiation, which may affect bone metabolism. Human MSCs (hMSCs) were committed to differentiate when either adipogenic or osteogenic media was added, supplemented with five increasing concentrations of amitriptyline (0.001-10 µM), venlafaxine (0.01-25 µM), or fluoxetine (0.001-10 µM). Alizarin red staining (mineralization), alkaline phosphatase (osteoblastogenesis), and oil red O (adipogenesis) assays were performed at timed intervals. In addition, cell viability was assessed using a MTT. We found that fluoxetine had a significant inhibitory effect on mineralization. Furthermore, adipogenic differentiation of hMSC was affected by the addition of amitriptyline, venlafaxine, and fluoxetine to the media. Finally, none of the tested medications significantly affected cell survival. This study showed a divergent effect of three antidepressants on hMSC differentiation, which appears to be independent of class and dose. As fluoxetine and amitriptyline, but not venlafaxine, affected both osteoblastogenesis and adipogenesis, this inhibitory effect could be associated to the high affinity of fluoxetine to the serotonin transporter system.

    The need for teamwork has grown significantly in today's organizations. Especially for online game communities, teamwork is an important means of online game players' engagement. This study aims to investigate the impacts of trust on players' teamwork with affective commitment and normative commitment as mediators. Furthermore, this research includes team experience as a moderator to compare the difference between different player groups. A model was proposed and tested on 296 online game players' data using structural equation modeling. Findings revealed that team experience moderated the relationship between trust and teamwork. The results indicated that trust promotes more teamwork only for players with high experience through affective commitment than those who with low experience. Implications of the findings are discussed.

    The aim of this study is to investigate whether organizational justice climate at the workplace level is associated with individual staff members' perceptions of care quality and affective commitment to the workplace. The study adopts a cross-sectional multi-level design. Data were collected using an electronic survey and a response rate of 75% was obtained. Organizational justice climate and affective commitment to the workplace were measured by items from Copenhagen Psychosocial Questionnaire and quality of care by three self-developed items. Non-managerial staff working at dental clinics with at least five respondents (n = 900 from 68 units) was included in analyses. A set of Level-2 random intercept models were built to predict individual-level organizational affective commitment and perceived quality of care from unit-level organizational justice climate, controlling for potential confounding by group size, gender, age, and occupation. The results of the empty model showed substantial between-unit variation for both affective commitment (ICC-1 = 0.17) and quality of care (ICC-1 = 0.12). The overall results showed that the shared perception of organizational justice climate at the clinical unit level was significantly associated with perceived quality of care and affective commitment to the organization (p < 0.001). Organizational justice climate at work unit level explained all variation in affective commitment among dental clinics and was associated with both the individual staff members' affective commitment and perceived quality of care. These findings suggest a potential for that addressing organizational justice climate may be a way to promote quality of care and enhancing affective commitment. However, longitudinal studies are needed to support causality in the examined relationships. Intervention research is also recommended to probe the effectiveness of actions increasing unit-level organizational justice climate and test their impact on quality of care and affective commitment.

    Umbilical cord blood (UCB) transplantation is associated with long periods of aplastic anaemia. This undesirable situation is due to the low cell dose available per unit of UCB and the immaturity of its progenitors. To overcome this, we present a cell culture strategy aimed at the expansion of the CD34 + population and the generation of granulocyte lineage-committed progenitors. Two culture products were produced after either 6 or 14days of in vitro expansion, and their characteristics compared to non-expanded UCB CD34 + controls in terms of phenotype, colony-forming activity and multilineage repopulation potential in NOD-scid IL2Rγ null mice. Both expanded cell products maintained rapid SCID repopulation activity similar to the non-expanded control, but 14-day cultured cells showed impaired long term SCID repopulation activity. The process was successfully scaled up to clinically relevant doses of 89×10 6 CD34 + cells committed to the granulocytic lineage and 3.9×10 9 neutrophil precursors in different maturation stages. Cell yields and biological properties presented by the cell product obtained after 14days in culture were superior and therefore this is proposed as the preferred production setup in a new type of dual transplant strategy to reduce aplastic periods, producing a transient repopulation before the definitive engraftment of the non-cultured UCB unit. Importantly, human telomerase reverse transcriptase activity was undetectable, c-myc expression levels were low and no genetic abnormalities were found, as determined by G-banding karyotype, further confirming the safety of the expanded product.

    Canadian researchers have developed the Spirit At Work (SAW) tool for identifying the experiences of individuals who are passionate about and energized by their work. This article describes (a) what registered nurses perceive as contributing to their personal SAW; and (b) the relationships among resonant leadership, structural empowerment concepts, psychological empowerment concepts, SAW concepts, job satisfaction, organizational commitment, and the demographic variables of experience, education, and rank in the RN workplace. The theoretical model was tested using LISREL 8.80 and survey data from 147 randomly selected RNs. Engaging work was found to account for 63% of the explained variance in the model's endogenous variables. Spiritual connection had a causal effect on organizational commitment, while resonant leadership and individual empowerment had significant causal influence on SAW, job satisfaction, and organizational commitment. These results strengthen those of previous studies reporting workplace structures/processes/contributions leading to superior care environments. Future studies will clarify the role of SAW in the workplace.

    Numerous challenges confront managers in the healthcare industry, making it increasingly difficult for healthcare organizations to gain and sustain a competitive advantage. Contemporary management challenges in the industry have many different origins (e.g., economic, financial, clinical, and legal), but there is growing recognition that some of management's greatest problems have organizational roots. Thus, healthcare organizations must examine their personnel management strategies to ensure that they are optimized for fostering a highly committed and productive workforce. Drawing on a sample of 2,522 employees spread across 312 departments within a large U.S. healthcare organization, this article examines the impact of a participative management climate on four employee-level outcomes that represent some of the greatest challenges in the healthcare industry: customer service, medical errors, burnout, and turnover intentions. This study provides clear evidence that employee perceptions of the extent to which their work climate is participative rather than authoritarian have important implications for critical work attitudes and behavior. Specifically, employees in highly participative work climates provided 14 percent better customer service, committed 26 percent fewer clinical errors, demonstrated 79 percent lower burnout, and felt 61 percent lower likelihood of leaving the organization than employees in more authoritarian work climates. These findings suggest that participative management initiatives have a significant impact on the commitment and productivity of individual employees, likely improving the patient care and effectiveness of healthcare organizations as a whole.

    Commitment, competencies and skills of people working in the health sector can significantly impact the performance and its reform process. In this study we attempted to analyse the commitment of state health officials and its implications for human resource practices in Gujarat. A self-administered questionnaire was used to measure commitment and its relationship with human resource (HR) variables. Employee's organizational commitment (OC) and professional commitment (PC) were measured using OC and PC scale. Fifty five medical officers from Gujarat participated in the study. Professional commitment of doctors (3.21 to 4.01) was found to be higher than their commitment to the organization (3.01 to 3.61). Doctors did not perceive greater fairness in the system on promotion (on the scale of 5, score: 2.55) and were of the view that the system still followed seniority based promotion (score: 3.42). Medical officers were upset about low autonomy in the department with regard to reward and recognition, accounting procedure, prioritization and synchronization of health programme and other administrative activities. Our study provided some support for positive effects of progressive HR practices on OC, specifically on affective and normative OC. Following initiatives were identified to foster a development climate among the health officials: providing opportunities for training, professional competency development, developing healthy relationship between superiors and subordinates, providing useful performance feedback, and recognising and rewarding performance. For reform process in the health sector to succeed, there is a need to promote high involvement of medical officers. There is a need to invest in developing leadership quality, supervision skills and developing autonomy in its public health institutions.

  9. Preferences, constraints or schemas of devotion? Exploring Norwegian mothers' withdrawals from high-commitment careers.

    2009-06-01

    Despite decades of focus on gender equality and work-family balance, parenthood still affects mothers' and fathers' careers differently. Drawing on in-depth interviews with Norwegian mothers who are relinquishing high-commitment careers of law and consultancy, this paper questions the adequacy of established explanations emphasizing constraints vs. individual preferences. Our sample of female professionals living in a well-developed welfare state is particularly apt to explore the processes and mechanisms upholding the statistically gendered pattern of women reducing their work commitment after childbirth. These doubly privileged mothers might be considered to have the best odds for combining career and work commitment with motherhood. Thus, we argue that the approach emphasizing practical constraints does not sufficiently account for the withdrawal from high-commitment careers among these female professionals. Nevertheless, we are not content with the claim of Preference Theory that this shift in commitment is merely a matter of 'not-so-dedicated' women discovering their 'genuine' preferences. Rather, in order to understand why and how this shift occurs, we explore the culturally constructed rationalities and schemas of both work and family devotions. We specifically examine the circumstances, mechanisms and steps in a seemingly individual process of making the shift in commitment from a promising career to a family-friendly job. Moreover, the analysis demonstrates how generous parental leave arrangements designed to enhance gender equality and work-family balance by simply reducing practical constraints may have limited--or even counterproductive--impact within high-commitment occupations where the 'irreplaceability' of workers is taken for granted. Our findings indicate that unless the culturally (re)produced discourses, demands and expectations of both work and family are exposed and challenged, even intentionally gender neutral work-family policies will continue to facilitate mothers' career withdrawals, expressed as modified individual preferences.

    Few studies explore the link between the psychological contracts and the commitment of nursing professionals in the healthcare sector, and how perceived breaches of the psychological contract can impact on nurses' commitment levels. This study explores the connections between the psychological contracts and organisational and professional commitment of nurses and nurse managers. Semi-structured interviews were conducted with nurses and nurse managers, to explore the connections between their psychological contracts and organisational and professional commitment. Large acute and small community organisation within the British National Health Service. 28 nurses and 11 nurse managers working within an acute and a community sector organisation - 20 and 19 in each organisation. Participants were selected through a process of purposive sampling, reflecting variations in terms of age, grade, ward and tenure. A discourse analysis was conducted on the qualitative data from the thirty nine semi-structured interviews. Two overall themes emerged, professional and managerial values. Professional values included the sub-themes: professional recognition; immediate work environment - leadership and peer support; professional development and progression. Sub-themes under managerial values included: involvement; general management; resource management. The findings suggest that nurses and nurse managers are governed by relational psychological contracts, underpinned by an affective and to a lesser extent normative commitment towards the nursing profession. They emphasise 'professional values', and professional commitment, as the basis for positive psychological contracts amongst nursing professionals. There was anecdotal evidence of relational psychological contract breach, with decreasing job satisfaction as the outcome of perceived psychological contract breach. Positive psychological contracts and commitment levels amongst nursing professionals can be supported by managers been aware and sensitive to nursing discourses, and managing their expectations through greater involvement and leadership development.

    The first protocol of ex vivo expansion that enabled almost total abrogation of postmyeloablative chemotherapy neutropenia was based on a three-cytokine cocktail (stem cell factor [SCF], granulocyte-colony-stimulating factor [G-CSF], pegylated-megakaryocyte growth and development factor [PEG-MGDF]) in a serum-free medium. Since the clinical-grade molecule MGDF is no longer available on the market, we evaluated its substitution by thrombopoietin (TPO). CD34+ cells of myeloma patients were expanded for 10 days in serum-free cultures with SCF, G-CSF, or MGDF (100 ng/mL) or with TPO (2.5, 10, 20, 50, and 100 ng/mL) instead of MGDF. Day 10 amplifications of total nucleated cells, CD34+ cells, committed progenitors (CFCs), the capacity of engraftment of NOD/SCID mice (SCID repopulating cells [SRCs]), and the immunophenotype of cells in expansion product (CD13, CD14, CD33, CD41, CD61) were analyzed. TPO in doses of 2.5 and 10 ng/mL exhibits an effect comparable to that of MGDF (100 ng/mL) on total, CD34+, and CFCs amplification. Compared to MGDF, TPO (starting at 10 ng/mL) enhances two- to threefold the percentage of megakaryocyte lineage cells (CD41+ and CD61+). Finally, TPO maintains or even enhances (depending on dose) SRC activity. The use of TPO instead of MGDF in our protocol is feasible without any negative effect on progenitor cell expansion. Furthermore, applied in dose of 10 or 100 ng/mL it could enhance both the stem cell activity and the percentage of megakaryocyte lineage cells in expansion product. © 2010 American Association of Blood Banks.

    Abstract A total of 105 countries have introduced IPV as of September 2016 of which 85 have procured the vaccine through UNICEF. The Global Eradication and Endgame Strategic Plan 2013-2018 called for the rapid introduction of at least one dose of IPV into routine immunization schedules in 126 all OPV-using countries by the end of 2015. At the time of initiating the procurement process, demand was estimated based on global modeling rather than individual country indications. In its capacity as procurement agency for the Global Polio Eradication Initiative and Gavi, the Vaccine Alliance, UNICEF set out to secure access to IPV supply for around 100 countries. Based on offers received, sufficient supply was awarded to two manufacturers to meet projected routine requirements. However, due to technical issues scaling up vaccine production and an unforecasted demand for IPV use in campaigns to interrupt wild polio virus and to control type 2 vaccine derived polio virus outbreaks, IPV supplies are severely constrained. Activities to stretch supplies and to suppress demand have been ongoing since 2014, including delaying IPV introduction in countries where risks of type 2 reintroduction are lower, implementing the multi-dose vial policy, and encouraging the use of fractional dose delivered intradermally. Despite these efforts, there is still insufficient IPV supply to meet demand. The impact of the supply situation on IPV introduction timelines in countries are the focus of this article, and based on lessons learned with the IPV introductions, it is recommended for future health programs with accelerated scale up of programs, to take a cautious approach on supply commitments, putting in place clear allocation criteria in case of shortages or delays and establishing a communication strategy vis a vis beneficiaries.

    Merger announcements cause stress among employees, often leading to low change commitment, especially among employees from the lower-status merger partner. Such stress influences how deeply employees process merger-relevant information. Previous research examined how merger patterns that preserve versus change status differences impact merger support, but did not address how employees' information processing may influence this relationship. The current research addresses this gap through a scenario experiment, focusing on the low-status merger partner. The interplay between merger patterns and information processing was examined regarding employees' prototypicality claims in relation to merger support. Results suggest that an integration-equality merger pattern increases change commitment via prototypicality claims in the new organization, conditional to employees' systematic information processing. © 2017 The British Psychological Society.

    Internationally, civil commitment laws have gone through substantial reforms in the past 50 years. Discernible shifts from the medically paternalistic to the excessively legalistic may be giving way to a blending of legislative intent under the rubric of therapeutic jurisprudence. In the light of those international movements, Shao and Xie describe how China's new mental health law shows the impact of these international and local influences on the development and practice of mental health law in China. The new Law was passed in 2012. It sets a broad vision for mental health services and mental health promotion in Chinese society as well as providing the legal framework for civil commitment. Practicalities of implementation may be highly significant in the success of the legislation. © 2015 American Academy of Psychiatry and the Law.

    Nurses suffer disproportionate levels of stress and are at risk of sickness-absence and turnover intentions, but there is a lack of research clarifying preventions. This study investigated the impact of inductions (job preparation courses) about mental health for nurses' job stress, general health, and organizational commitment. Data from 6,656 nurses were analyzed using structural equation modeling (SEM), showing that mental health inductions increase nurses' job satisfaction, which reduces their occupational stress and improves their health. SEM showed that these occupational health benefits increase the nurses' commitment to the organization. Job satisfaction (feeling valued, rewarded) also had a direct effect on nurses' intentions to continue working for the organization. Mental health inductions are therefore beneficial beyond job performance: they increase occupational health in the nursing profession.

    A sample of tritiated lanthanum nickel aluminum alloy (LaNi4.25Al0.75 or LANA.75) similar to that used at the Savannah River Site Tritium Facilities was analyzed to estimate the particle size distribution of this metal tritide powder and the rate at which this material dissolves in the human respiratory tract after it is inhaled. This information is used to calculate the committed effective dose received by a worker after inhaling the material. These doses, which were calculated using the same methodology given in the U.S. Department of Energy Tritium Handbook, are presented as inhalation intake-to-dose conversion factors (DCF). The DCF for this metal tritide was determined to be 9.4 × 10 Sv Bq, which is less than the DCF for tritiated water. Therefore, the radiation worker bioassay programs designed for tritiated water are adequate to monitor for intakes of this material.

    Imatinib mesylate (Gleevec) inhibits Abl1, c-Kit, and related protein tyrosine kinases (PTKs) and serves as a therapeutic for chronic myelogenous leukemia and gastrointestinal stromal tumors. Imatinib also has efficacy against various pathogens, including pathogenic mycobacteria, where it decreases bacterial load in mice, albeit at doses below those used for treating cancer. We report that imatinib at such low doses unexpectedly induces differentiation of hematopoietic stem cells and progenitors in the bone marrow, augments myelopoiesis but not lymphopoiesis, and increases numbers of myeloid cells in blood and spleen. Whereas progenitor differentiation relies on partial inhibition of c-Kit by imatinib, lineage commitment depends upon inhibition of other PTKs. Thus, imatinib mimics “emergency hematopoiesis,” a physiological innate immune response to infection. Increasing neutrophil numbers by adoptive transfer sufficed to reduce mycobacterial load, and imatinib reduced bacterial load of Franciscella spp., which do not utilize imatinib-sensitive PTKs for pathogenesis. Thus, potentiation of the immune response by imatinib at low doses may facilitate clearance of diverse microbial pathogens. PMID:25822986

    Background Despite the wealth of studies demonstrating the impairing effects of alcohol on behavioral inhibition, less is known regarding effects of the drug on attentional inhibition (i.e., the ability to ignore distracting stimuli in the environment in order to focus attention on relevant information). The current study examined alcohol impairment of both behavioral and attentional inhibition, as well as potential associations between the two mechanisms of inhibitory control. Methods Men (n = 27) and women (n = 21) performed a measure of behavioral inhibition (cued go/no-go task) and a measure of attentional inhibition (delayed ocular return task) following three doses of alcohol: 0.65 g/kg, 0.45 g/kg, and 0.0 g/kg (placebo). Results Alcohol impaired both behavioral and attentional inhibition relative to placebo; however, correlational analyses revealed no associations between measures of behavioral and attentional inhibition following any dose. Additionally, men committed more inhibitory failures on the behavioral inhibition task, whereas women committed more inhibitory failures on the attentional inhibition task. Conclusions These findings suggest that behavioral and attentional inhibition are equally sensitive to the impairing effects of alcohol, yet represent distinct components of inhibitory control. Additionally, the observed gender differences in control of behavior and attention could have important implications regarding negative consequences associated with alcohol-induced disinhibition in men and women.

    This paper deals with the distribution and activity intake of 210Po and 210Pb in food, diet, and potable water samples of the Goa region and the estimated committed effective dose due to ingestion of these radionuclides. The activity concentrations of 210Po and 210Pb were determined in about 30 food and diet samples from different places of Goa in order to know the distribution and intake of these radionuclides. The activity concentration of 210Po in fish and prawn samples were significantly higher than concentrations found in vegetable and rice samples. Higher concentrations of 210Po and 210Pb were observed in leafy vegetables than in non-leafy vegetables. Among the diet samples the activity concentrations of 210Po and 210Pb in non-vegetarian meal samples were relatively higher than in vegetarian meal and breakfast samples. The committed effective dose due to annual intake of 210Po was found to be 94.6 microSv, 49.1 microSv, 10.5 microSv, and 2.2 microSv and that of 210Pb found to be 81.6 microSv, 59.9 microSv, 14.6 microSv, and 2.0 microSv for the ingestion of non-vegetarian meal, vegetarian meal, breakfast, and potable water, respectively.

    The environmental effects of receipt and burial of low level naval waste are assessed. This low level waste was sent to the NRC-licensed burial ground operated by Chem-Nuclear Systems, Inc., at Barnwell, South Carolina. The DOE announced that DOE-generated low level waste would no longer be buried at commercial waste burial sites. The SRP was selected to receive the Naval waste described in this analysis. Receipt and burial of these wastes will have a negligible effect on SRP's environment and increase only sightly the environmental effects of the SRP operations discussed in the EIS on SRP waste management operations. The environmental effects of burial of this waste at Chem-Nuclear Burial Ground or at the SRP Burial Ground are described in this environmental analysis to permit assessment of incremental effects caused by the decision to bury this Naval waste in the SRP Burial Ground rather than in the Barnwell Burial Ground. The radiological effects from burial of this waste in either the SRP or Chem-Nuclear Burial Ground are very small when compared to those from natural background radiation or to the annual population dose commitment from operation of SRP. The environmental effects of burial at SRP to dose commitments normally received by the population surrounding SRP are compared.

    To explore the relationships between climate for well-being, economic and social exchange, affective ward commitment and job strain among nurses in the Netherlands. This study focuses on the immediate work environment of nurses by exploring the way nurse perceptions about the extent to which the ward values and cares for their welfare influence their levels of affective ward commitment and job strain. Second, this study extends previous research on exchange relationships by examining the potential differential impact of social and economic exchange relationships on commitment and job strain. A cross-sectional survey among nurses. The study was conducted in the Netherlands in 2011. Validated measures of climate for well-being, social exchange, economic exchange, ward commitment and job strain were used. Hypotheses were tested using regression analyses. MacKinnon et al.'s (2007) guidelines to assess mediation were used. The response rate was 41% (271 questionnaires). The results show that climate for well-being positively influences social exchange relationships, which are in turn associated with enhanced ward commitment and reduced strain. Climate for well-being negatively influences evaluations of economic exchange, which are in turn negatively related to ward commitment. This study shows that nurses use the information available in their immediate work environment to evaluate their exchange relationship with the organization. Second, the findings point towards the importance of economic and social exchange relationships as a mechanism between climate for well-being on the one hand and affective ward commitment and job strain on the other hand. © 2013 John Wiley & Sons Ltd.

  11. The impact of role stress on workers' behaviour through job satisfaction and organizational commitment.

    Antón, Concha

    2009-06-01

    Dysfunctions in role performance have been associated with a large number of consequences, almost always negative, which affect the well-being of workers and the functioning of organizations. An individual's experience of receiving incompatible or conflicting requests (role conflict) and/or the lack of enough information to carry out his/her job (role ambiguity) are causes of role stress. According to previous theory, role ambiguity and conflict decrease workers' performance and are positively related to the probability of workers leaving the organization. Job satisfaction refers to a positive evaluation of a job, while organizational commitment refers to an employee's attachment to the organization. The affective dimensions of organizational commitment and job satisfaction are considered to be important predictors of turnover intention, absenteeism, and job performance. In the literature, role conflict and ambiguity have been proposed as determining factors of workers' job satisfaction and their commitment towards the organization. The role of job satisfaction and organizational commitment were analysed as variables that should mediate between role ambiguity and conflict and employees' behaviour. The hypotheses were confirmed by means of path analysis carried out with data obtained from a sample of Spanish blue-collar workers employed by a bus company and a water supply company. Role stressors were negatively related to affective commitment mediated through job satisfaction. Affective commitment to the organization exerted a positive influence on performance and reduces the withdrawal behaviour analysed— intention to leave and absenteeism—although the strongest predictor of intention to leave was, in this study, job satisfaction.

  12. Dose Calculation For Accidental Release Of Radioactive Cloud Passing Over Jeddah

    2011-12-01

    For the evaluation of doses after the reactor accident, in particular for the inhalation dose, a thorough knowledge of the concentration of the various radionuclide in air during the passage of the plume is required. In this paper we present an application of the Gaussian Plume Model (GPM) to calculate the atmospheric dispersion and airborne radionuclide concentration resulting from radioactive cloud over the city of Jeddah (KSA). The radioactive cloud is assumed to be emitted from a reactor of 10 MW power in postulated accidental release. Committed effective doses (CEDs) to the public at different distance from the source to the receptor are calculated. The calculations were based on meteorological condition and data of the Jeddah site. These data are: pasquill atmospheric stability is the class B and the wind speed is 2.4m/s at 10m height in the N direction. The residence time of some radionuclides considered in this study were calculated. The results indicate that, the values of doses first increase with distance, reach a maximum value and then gradually decrease. The total dose received by human is estimated by using the estimated values of residence time of each radioactive pollutant at different distances.

    Medical teachers report both positive and negative experiences, but these impacts are not well understood. In particular, the experience of faculty in relationship-centered education is unknown. We sought to assess the benefits to teachers of the Healer's Art, a popular international medical school elective course. We performed quantitative and qualitative analyses of course evaluations completed by 2009-10 Healer's Art faculty from 17 schools. Ninety-nine of 117 faculty (84.6%) completed the evaluation. No differences in quantitative responses based on gender, specialty, medical school, or year of graduation were observed. Respondents were likely or very likely to agree that the course was useful, positively impacted clinical work and teaching, and increased overall commitment to teaching. In describing the benefits of teaching in the Healer's Art, faculty emphasized four themes: Personal Response to Medicine, Professional Growth, Greater Connection, and Greater Empathy and Respect for Students. Healer's Art faculty report personal and professional benefits, as well as increased commitment to teaching and to a relationship-centered educational process.

    2010-01-01

    Processes in generating, transporting, and dissipating the airborne dust particles are global phenomena -African dust regularly reaching the Alps; Asian dust seasonally crossing the Pacific into North America, and ultimately the Atlantic into Europe. One of the vital biogeochemical roles dust storms play in Earth's ecosystem is routinely mobilizing mineral dust, as a source of iron, from deserts into oceans for fertilizing the growth of phytoplankton -the basis of the oceanic food chain. Similarly, these dust-laden airs also supply crucial nutrients for the soil of tropical rain forests, the so-called womb of life that hosts 50-90% of the species on Earth. With massive amounts of dust lifted from desert regions and injected into the atmosphere, however, these dust storms often affect daily activities in dramatic ways: pushing grit through windows and doors, forcing people to stay indoors, causing breathing problems, reducing visibility and delaying flights, and by and large creating chaos. Thus, both increasing and decreasing concentrations of doses result in harmful biological effects; so do the airborne dust particles to our Living Earth. Since 1997 NASA has been successfully launching a series of satellites - the Earth Observing System - to intensively study, and gain a better understanding of, the Earth as an integrated system. Through participation in many satellite remote-sensing/retrieval and validation projects over the years, we have gradually developed and refined the SMART (Surface-sensing Measurements for Atmospheric Radiative Transfer) and COMMIT (Chemical, Optical & Microphysical Measurements of In-situ Troposphere) mobile observatories, a suite of surface remote sensing and in-situ instruments that proved to be vital in providing high temporal measurements, which complement the satellite observations. In this talk, we will present SMART-COMMIT which has played key roles, serving as network or supersite, in major international research projects such as the Joint Aerosol Monsoon Experiment (JAMEX), a core element of the Asian Monsoon Years (AMY, 2008-2012). SMART-COMMIT deployments during 2008 AMY/JAMEX were conducted in northwestern China to characterize the properties of dust-laden aerosols. In 2009, SMART-COMMIT also participated in the JAMEX/RAJO-MEGHA (Radiation, Aerosol Joint Observations-Monsoon Experiment in the Gangetic-Himalayan Area; Sanskrit for Dust-Cloud) to study the aerosol properties, solar absorption and the associated atmospheric warming, and the climatic impact of elevated aerosols during the premonsoon season in South Asia. To fully characterize the properties of airborne dust in the field is an important but challenging task. In this seminar, we will present our recent measurements and retrievals of airborne dust properties.

    1980-01-01

    Construction and operation of a 60-unit (300 GW) domestic SPS over the period 2000 to 2030 would stress many segments of U.S. society. A significant commitment of resources (land, energy, materials) would be required, and a substantial proportion of them would have to be committed prior to the production of any SPS electricity. Forty-four concerns about the SPS were identified via a public outreach experiment involving 9000 individuals from three special interest organizations. The concerns focused on environmental impacts (particularly the effects of microwave radiation) and the centralizing tendency of the SPS on society.

    This study presents the results of (137)Cs and (40)K radionuclide concentrations in mussel (Mytilus galloprovincialis) samples collected during the period of February-November 2014 from twelve different stations within the border of the eastern Black Sea region of Turkey. Also, these radionuclide concentrations were determined in sea water and sediment samples. The activity concentrations in seawater, sediment and mussel tissue samples were between 1.12-1.69mBqL(-1), 3.26-30.74 and 1.61-3.16Bqkg(-1) for (137)Cs and 231.41-399.49mBqL(-1), 215.71-450.07 and 286.84-382.16Bqkg(-1) for (40)K, respectively. These values are also in accordance with the concentrations reported for similar regions. Additionally, radiological impact parameters such as daily intake of (137)Cs and (40)K, annual committed effective dose and carcinogenic risk due to the consumption of mussel were calculated and compared with the international data. Lifetime cancer risk values are lower than the limit of 10(-3). Copyright © 2016 Elsevier Ltd. All rights reserved.

    At the first time for the period after the Chernobyl NPP accident the nature of the redistribution of the 90 Sr concentrations in components of the ecosystems of the salt lakes of the Crimea were identified and described. Concentration of 90 Sr in water of the salt lakes depends on the sources of the inflow this radionuclide into aquatic ecosystems and salinity level of lakes water. Until April 2014 the flow of the Dnieper river water through the Northern-Crimean canal was more important factor of contamination of salt lakes of the Crimea by 90 Sr, than atmospheric fallout of this radionuclide after the Chernobyl NPP accident. Concentrations of 90 Sr in water of the salt lakes of the Crimea exceeded 2.4-156.5 times its concentrations in their bottom sediments. The 90 Sr dose commitments to hydrophytes, which were sampled from the salt lakes of the Crimea have not reached values which could impact them during entire the after-accident period.

  19. Understanding patient compliance and persistence with osteoporosis therapy.

    PubMed

    Gold, Deborah T

    2011-04-01

    Chronic non-terminal diseases, including postmenopausal osteoporosis, are associated with poor treatment compliance and persistence. The longer a patient with osteoporosis complies and persists with treatment, the lower the risk of fracture. Retrospective studies with emphasis on real-world data have led to a greater understanding of the factors affecting medication compliance and persistence, and their association with improved treatment outcomes. However, these data do not contain information about patient choices of medication or patient commitment to particular medication regimens. Patient preferences can affect compliance and persistence behaviours. While recent evidence questions the importance of dosing regimen in patient preferences, other recent data show that medication efficacy and safety remain the most important determinants of patient preference. Informed patient decision making about treatment options, adverse effects and outcomes can have a beneficial impact on medication-taking behaviour. Healthcare professionals play a crucial role in the management of factors associated with poor compliance and persistence with osteoporosis therapies. Education about disease consequences and differences among treatment options, as well as treatment monitoring and positive reinforcement, are crucial to improving medication compliance and persistence in osteoporotic patients.

    Workers in repair shops of vehicles (cars, buses, truck, etc.) clean carburetors, check fuel distribution, and perform oil changes and greasing. To explore the exposure pathway of (238)U and (232)Th and its decay products to the skin of mechanic workers, these radionuclides were measured inside petrol, gas-oil, and lubricant material samples by means of CR-39 and LR-115 type II solid state nuclear track detectors (SSNTDs), and corresponding annual committed equivalent doses to skin were determined. The maximum total equivalent effective dose to skin due to the (238)U and (232)Th series from the application of different petrol, gas-oil, and lubricant samples by mechanic workers was found equal to 1.2 mSv y(-1) cm(-2).

    Following a radiation emergency, the affected public and the first responders may need to be quickly assessed for internal contamination by the radionuclides involved. Urine bioassay is one of the most commonly used methods for assessing radionuclide intake and radiation dose. This paper attempts to derive the sensitivity requirements (from inhalation exposure) for the urine bioassay techniques for the top 10 high-risk radionuclides that might be used in a terrorist attack. The requirements are based on a proposed reference dose to adults of 0.1 Sv (CED, committed effective dose). In addition, requirements related to sample turnaround time and field deployability of the assay techniques are also discussed. A review of currently available assay techniques summarized in this paper reveals that method development for ²⁴¹Am, ²²⁶Ra, ²³⁸Pu, and ⁹⁰Sr urine bioassay is needed.

  2. G-CSF-primed BM for allogeneic SCT: revisited.

    PubMed

    2015-07-01

    G-SCF-mobilized PBSC (GPB) grafts have a higher cell dose and somewhat more committed progenitor cells than steady-state BM (SBM), resulting in faster engraftment and faster immunological reconstitution. On the other hand, transplant related mortality (TRM), disease-free survival (DFS) and overall survival (OS) are similar both for PB and for BM. In contrast to SBM, G-CSF-primed BM (GBM) grafts stimulate HSC proliferation, increasing cell dose and thus resulting in faster engraftment because of higher cell dose infused, or because of treatment with G-CSF. Furthermore, GBM may induce tolerance and functional modulations in donor hematopoiesis and immunity, further reducing GVHD incidence, which is already lower with SBM compared with GPB grafts. Overall, a growing body of clinical evidence suggests that GBM transplants may share the advantages of GPB transplantations, without the associated increased risk of GVHD, and might be an attractive graft source for allogeneic SCTs.

    In the case of accidental release of Uranium-238 ({sup 238}U) radionuclides in a nuclear facility or in the environment, internal contamination by either acute or chronic exposure has the potential to induce both radiological and chemical toxic effects. A study was conducted to estimate the {sup 238}U radionuclide concentration in the long beans using Induced Coupled Mass Plasma-Spectrometry (ICP-MS). {sup 238}U radionuclide is a naturally occurring radioactive material that can be found in soil and can be transferred to the long bean (Vigna unguiculata subsp. Sesquapedalis) directly or indirectly via water or air. Kidney and liver are the major sitesmore » of deposition of {sup 238}U radionuclide. The obtained dose exposed in the liver and kidney is used to assess the safety level for public intake of {sup 238}U radionuclide from the consumption of long beans. The concentration of {sup 238}U radionuclide measured in long bean samples was 0.0226 ± 0.0009 mg/kg. Total activity of {sup 238}U radionuclide was 0.0044 ± 0.0002 Bq/day with the daily intake of 0.3545 ± 0.0143 µg/day and the annual committed effective dose due to ingestion of {sup 238}U radionuclide in long beans was 0.2230 ± 0.0087 µSv/year. The committed equivalent dose of {sup 238}U radionuclide from the assessment in the liver and kidney are 0.4198 ± 0.0165 nSv and 10.9335 ± 0.4288 nSv. The risk of cancer of {sup 238}U radionuclide was determined to be (86.0466 ± 3.3748) × 10-9. Thus, the results concluded that {sup 238}U radionuclide in local long beans was in the permitted level and safe to consume without posing any significant radiological threat to population.« less

    The radioactive gas radon, intermediate term of the decay series of uranium and thorium, is the main contamination source of underground places and may be a risk for high concentration and long exposure time. European and Italian law requires radon concentration to be measured in workplaces and, if the "action level" of 500 Bq/m3 is reached, proper actions must be made in order to decrease the dose commitment. Considering natural showcaves or artificial cavities open to public, the exposition of the visitors is frequently small, due to the short residence time, but accompanying people, remaining underground for long time, may be subject to appreciable dose and the radon concentration should therefore be monitored. The high humidity in natural caves may impair the use of some measuring devices. Therefore, different detection methods were compared (ZnS scintillation counters, E-PERM electret ionisation chambers, cellulose nitrate alpha-track dosimeters) to select the best procedure for long-term investigation. The LR-115 (Kodak) alpha-track dosimeters were insensitive to humidity and permitted to monitor a great number of places at the same time. Measurements have been carried out in the speleological and archaeological site of the Toirano's Caves (Savona, Liguria, Italy) and several points were monitored for two years. Radon concentration strongly depends on the site and changes during the year, due to the difference between internal and external temperature. The maximum dose commitment during the visitors tour, considering the average yearly value of radon concentration, was found to be between 1.5 and 4 microSv. It was found that no risk exists for visitors, but the evaluation of the dose absorbed by the guides and their classification according to the radiation protection law requires a complete monitoring of the average yearly concentration of radon and of the total time spent by each worker into the cave.

    The science of morality has drawn heavily on well-controlled but artificial laboratory settings. To study everyday morality, we repeatedly assessed moral or immoral acts and experiences in a large (N = 1252) sample using ecological momentary assessment. Moral experiences were surprisingly frequent and manifold. Liberals and conservatives emphasized somewhat different moral dimensions. Religious and nonreligious participants did not differ in the likelihood or quality of committed moral and immoral acts. Being the target of moral or immoral deeds had the strongest impact on happiness, whereas committing moral or immoral deeds had the strongest impact on sense of purpose. Analyses of daily dynamics revealed evidence for both moral contagion and moral licensing. In sum, morality science may benefit from a closer look at the antecedents, dynamics, and consequences of everyday moral experience.

    The detonation of a radiological dispersion device or other radiological incidents could result in widespread releases of radioactive materials and intakes of radionuclides by affected individuals. Transportable radiation monitoring instruments could be used to measure radiation from gamma-emitting radionuclides in the body for triaging individuals and assigning priorities to their bioassay samples for in vitro assessments. The present study derived sets of calibration factors for four instruments: the Ludlum Model 44-2 gamma scintillator, a survey meter containing a 2.54 × 2.54-cm NaI(Tl) crystal; the Captus 3000 thyroid uptake probe, which contains a 5.08 × 5.08-cm NaI(Tl) crystal; the Transportable Portal Monitor Model TPM-903B, which contains two 3.81 × 7.62 × 182.9-cm polyvinyltoluene plastic scintillators; and a generic instrument, such as an ionization chamber, that measures exposure rates. The calibration factors enable these instruments to be used for assessing inhaled or ingested intakes of any of four radionuclides: Co, I, Cs, and Ir. The derivations used biokinetic models embodied in the DCAL computer software system developed by the Oak Ridge National Laboratory and Monte Carlo simulations using the MCNPX radiation transport code. The three physical instruments were represented by MCNP models that were developed previously. The affected individuals comprised children of five ages who were represented by the revised Oak Ridge National Laboratory pediatric phantoms, and adult men and adult women represented by the Adult Reference Computational Phantoms described in Publication 110 of the International Commission on Radiological Protection. These calibration factors can be used to calculate intakes; the intakes can be converted to committed doses by the use of tabulated dose coefficients. These calibration factors also constitute input data to the ICAT computer program, an interactive Microsoft Windows-based software package that estimates intakes of radionuclides and cumulative and committed effective doses, based on measurements made with these instruments. This program constitutes a convenient tool for assessing intakes and doses without consulting tabulated calibration factors and dose coefficients.

    2018-03-01

    Despite having been overlooked in the standard histories of the UK and the European Community, gender politics and gender policies played a significant role in Britain's applications for membership in the EEC in the 1960s. Joining the European Community required that Britain comply with Article 119 on equal pay for equal work. A combination of domestic feminist and labour movement activism, the commitment of unions and parties, and the internationalization of formal commitments to women's rights constituted internal and external pressures for the passage of an Equal Pay Act in 1970. The article argues that the formal legislative commitment to gender pay equality, changing public attitudes towards women's employment, and European membership impacted further domestic social policy reform and slowly began to shift government attitudes towards gender equality.

    2012-12-01

    The aim of the present study was to assess the effectiveness of an Acceptance and Commitment Therapy group intervention program for adults who stutter (N=20). The program consisted of 2-h therapeutic sessions conducted weekly for eight consecutive weeks. It was an integrated program designed to improve: (a) psychosocial functioning, (b) readiness for therapy and change, (c) utilisation of mindfulness skills and psychological flexibility, and (d) frequency of stuttering. The findings provide innovative evidence for Acceptance and Commitment Therapy as an effective intervention with statistically significant improvements in psychosocial functioning, preparation for change and therapy, utilisation of mindfulness skills, and overall speech fluency. Follow-up data collected at three months post-treatment revealed that therapeutic gains were successfully maintained over time. These findings enhance the understanding of the impact of stuttering on psychological wellbeing and offer a new perspective on what might constitute successful stuttering treatment. Further, clinical research support is provided for Acceptance and Commitment Therapy delivered in a group format as a promising and novel intervention for adults who stutter.

    Adequate dose management during computed tomography is important. In the present study, the dosimetric application software ImPACT was added to a functional calculator of the size-specific dose estimate and was part of the scan settings for the auto exposure control (AEC) technique. This study aimed to assess the practicality and accuracy of the modified ImPACT software for dose estimation. We compared the conversion factors identified by the software with the values reported by the American Association of Physicists in Medicine Task Group 204, and we noted similar results. Moreover, doses were calculated with the AEC technique and a fixed-tube current of 200 mA for the chest-pelvis region. The modified ImPACT software could estimate each organ dose, which was based on the modulated tube current. The ability to perform beneficial modifications indicates the flexibility of the ImPACT software. The ImPACT software can be further modified for estimation of other doses. © The Author 2016.

    Because of the limited number of studies that have examined the motives for childhood animal cruelty, researchers continue to suggest that further systematic study is needed. In a replication of the Hensley and Tallichet study and based on survey data from 180 inmates at one medium- and one maximum-security prison in a southern U.S. state, the present study seeks to further develop this understanding by examining the impact of demographic and situational factors on a range of animal cruelty motivations. Of the 180 inmates, 103 (57%) committed acts of animal cruelty. Logistic regression analyses revealed that respondents who committed childhood animal cruelty out of anger were less likely to cover up their behavior and to be upset by their actions but were more likely to have repeated it. Those who committed animal cruelty to shock others were more likely to reside in urban areas and to have done it alone. Furthermore, respondents who committed animal cruelty for sexual reasons were more likely to have covered up their actions and to have engaged in it repeatedly.

    The variation in suicide patterns across ethnic groups with different religious background is a puzzling social phenomenon. This study sought to examine the impact of religious commitment and attitudes toward suicide on suicidal behaviors of college students across major ethnic and religious groups in a multicultural society of Malaysia. A total of 139 college students completed Religious Commitment Inventory-10, Attitudes Toward Suicide Scale, and Suicidal Behavior Questionnaire-Revised. Findings showed significant discrepancies in attitudes toward suicide, but not suicidal behaviors across ethnic and religious groups. Suicide acceptance significantly affected suicidal behaviors as well. Although religious commitment is not associated with suicidal behaviors, its deviation is reflected in students' acceptance of suicide. Additionally, college students' suicide risk, lifetime, and recent suicide ideation, as well as their likelihood of future suicide attempt can be associated with their acceptance of suicide. The influence of attitudes toward suicide and religion, therefore, should be taken into consideration while implementing suicide prevention programs as it helps shape the norms about suicide among youths.

    This study aimed to describe the perceived level of organizational commitment and organizational culture of Korean American Registered Nurses (KARNs) and to investigate predictors of job satisfaction. A total of 163 KARNs working in U.S. hospitals responded to a Web survey. Descriptive analysis, t test, analysis of variance, and stepwise regressions were used for data analysis. KARNs reported moderate levels of job satisfaction (3.5 ± 0.58). Job satisfaction was positively correlated with both organizational commitment (r = .85, p < .001) and culture (r = .66, p < .001). KARNs who were aged ≥50, married, hospital-employed, had longer nursing experience, and experienced turnover at least once were more likely to report higher job satisfaction compared with other nurses. Organizational commitment, culture, marital status, and workplace were significant predictors of and explained 76.8% of the variance in job satisfaction. This study provides evidence to help nursing managers and health policy makers develop educational programs aimed at enhancing job satisfaction and retention of KARNs. © The Author(s) 2016.

    Background Use of antidepressant medications has been linked to detrimental impacts on bone mineral density and osteoporosis; however, the cellular basis behind these observations remains poorly understood. The effect does not appear to be homogeneous across the whole class of drugs and may be linked to affinity for the serotonin transporter system. In this study, we hypothesized that antidepressants have a class- and dose-dependent effect on mesenchymal stem cell (MSC) differentiation, which may affect bone metabolism. Methods Human MSCs (hMSCs) were committed to differentiate when either adipogenic or osteogenic media was added, supplemented with five increasing concentrations of amitriptyline (0.001–10 µM), venlafaxine (0.01–25 µM), or fluoxetine (0.001–10 µM). Alizarin red staining (mineralization), alkaline phosphatase (osteoblastogenesis), and oil red O (adipogenesis) assays were performed at timed intervals. In addition, cell viability was assessed using a MTT. Results We found that fluoxetine had a significant inhibitory effect on mineralization. Furthermore, adipogenic differentiation of hMSC was affected by the addition of amitriptyline, venlafaxine, and fluoxetine to the media. Finally, none of the tested medications significantly affected cell survival. Conclusions This study showed a divergent effect of three antidepressants on hMSC differentiation, which appears to be independent of class and dose. As fluoxetine and amitriptyline, but not venlafaxine, affected both osteoblastogenesis and adipogenesis, this inhibitory effect could be associated to the high affinity of fluoxetine to the serotonin transporter system.

    Nurse turnover is an important contributing factor to the worldwide nursing shortage. Many studies have examined the antecedents of nurse turnover to gain a better understanding of the problem and help hospitals reduce their turnover rates. However, an important shortcoming of this research stream is its exclusive focus on explaining turnover behavior of the "average nurse", thereby disregarding individual differences between nurses and groups of nurses. To examine individual differences in the relationships between two crucial turnover antecedents - job satisfaction and organizational commitment - and nurse turnover intention. A sample of 287 nurses working for a variety of Belgian hospitals participated in the study. A survey method was used to collect quantitative data, which were analyzed through standard multiple linear regression, mixture regression models and t-tests. In the total sample of hospital nurses, both job satisfaction and organizational commitment significantly predicted nurse turnover intention. However, subsequent individual differences analyses revealed the existence of two subgroups of nurses. In the satisfaction focused group, only job satisfaction was found to predict nurse turnover intention, whereas in the satisfaction and commitment focused group both job satisfaction and organizational commitment were related to turnover intention. Furthermore, nurses in the latter group displayed stronger turnover intention, were significantly younger and had less job tenure and organizational tenure than nurses in the satisfaction focused group. The debate on the antecedents of nurse turnover still continues, as the existing models fail to fully grasp nurse turnover. The present study identifies individual differences in nurse turnover antecedents among groups of nurses as a possible reason for the absence of one comprehensive turnover model that holds for the general nursing population. Further studies are needed in order to capture the total impact of the underlying individual differences in nurse turnover antecedents. 2011 Elsevier Ltd. All rights reserved.

    Nurses play an important role in medical and health services but anxiety among those in this profession is widespread. Anxiety not only damages the physical and mental health of the individual, but also reduces the efficiency of their work and the quality of care, ultimately impacting on patient care. Therefore, it is necessary to elucidate the factors that lead to anxiety and explore measures to reduce the impact these factors have on nurses. The purpose of this study was to investigate the serial-multiple mediation of psychological capital (PsyCap), organizational commitment, job burnout, and anxiety among Chinese female nurses. A cross-sectional stratified cluster sampling study. The study consisted of 1354 Chinese female nurses from two tertiary grade A hospitals in Heilongjiang Province, China. The Zung Self-Rating Anxiety Scale, the Chinese psychological capital questionnaire, the Chinese Maslach Burnout Inventory, and the Chinese Employee Organizational Commitment Questionnaire were used to gather data. Descriptive analysis, independent-samples T-test, one-way analysis of variance, Spearman correlation analyses, ordinary least-squares regression and the bootstrap method were used to analyze data. The prevalence rate of anxiety among nurses was found to be 41.1%, and there were significant differences in anxiety symptoms in age (F = 15.54, p < 0.001) and marital status (F = 5.41, p < 0.001), but not education (F = 1.50, p = 0.224) among nurses. Overall, the serial-multiple mediation of organizational commitment and job burnout in the relationship between PsyCap and anxiety was found to be statistically significant. The results of the present study showed that positive PsyCap was sequentially associated with increased organizational commitment first, and then decreased job burnout, which was in turn related to reduced symptoms of anxiety among female nurses.

    The purpose of this study was to examine the effectiveness of acceptance and commitment therapy (ACT) for older adults with chronic pain. Secondarily, we examined the associations between changes on processes of psychological flexibility and treatment outcome variables. Participants were 60 adults with chronic pain age 65 and older selected from a larger consecutive sample of 928 adults of any age. All participants had longstanding pain that was associated with significant distress and disability. Participants completed measures of pain, functioning, and depression, and processes of psychological flexibility at baseline, immediately post-treatment, and at a 9-month follow-up. Treatment consisted of a 2- or 4-week residential program based on principles of ACT delivered by an interdisciplinary team. Treatment was designed to increase daily functioning by enhancing key processes of psychological flexibility, including openness, awareness, and committed action. Participants showed significant improvements in functioning and mental health at posttreatment. Participants also showed significant increases in pain acceptance and committed action from pre- to post-treatment. Small effect sizes were observed for most treatment outcome and process variables in the pre-treatment to follow-up intervals; however, these improvements were not statistically significant. In secondary analyses, changes in facets of psychological flexibility were significantly associated with improvements in social functioning and mental health. This study supports the potential effectiveness of ACT for chronic pain among older adults. Future research is needed to determine how to maximize the impact of this treatment, particularly through greater impact on psychological flexibility.

    By 2030, numbers and proportions of older adults with substance-use problems are expected to increase. While risk factors for problem drinking in late life have been identified, it remains unknown whether these factors drive daily drinking among older problem drinkers. This study examined the daily drivers of drinking among problem drinkers, moderated by age, utilizing ecological momentary assessment (EMA). Participants (N = 139), ages 20-73, received daily EMA online surveys completed via a smartphone prior to initiation of treatment. Multilevel modeling tested the moderating impact of age on within- and between-person relationships between drinking and focal predictors (mood, loneliness, boredom, stress, poor sleep, social factors, alcohol salience, commitment and confidence not to drink heavily). Older adults reported greater alcohol consumption when daily boredom levels were higher. Heavier drinking among younger adults was associated with poorer sleep quality. Greater daily confidence, daily commitment and daily alcohol salience did not impact drinking to the same extent for older adults as for younger adults. Greater person-level commitment predicted reduced drinking equivalently across age, but low person-level commitment predicted greater drinking among older adults compared to their younger counterparts. Older adults may have unique daily drivers of drinking that are not fully realized in current research and intervention efforts. Addressing the growing substance-use treatment needs among this population will require identifying the unique drivers of drinking among older adults, such as boredom, when compared to younger adults.

    This study examines the perceptions of registered nurses of social capital, organisational commitment and customer-oriented prosocial behaviour. Additionally, this study also addresses a conceptual model for testing how registered nurses' perceptions of three types of social capital influence their organisational commitment, in turn intensifying customer-oriented prosocial behaviour, including role-prescribed customer service and extra-role customer service. Customer-oriented prosocial behaviour explains differences in job satisfaction and job performance. However, the critical role of customer orientation in the hospital setting has yet to be explored. Survey. The survey was conducted to obtain data from registered nurses working for a large Taiwanese medical centre, yielding 797 usable responses and a satisfactory response rate of 86.7%. The partial least squares method was adopted to obtain parameter estimates and test proposed hypotheses. The study measurements display satisfactory reliability, as well as both convergent and discriminant validities. All hypotheses were supported. Empirical results indicate that registered nurses' perceptions of social capital were significantly impacted the extent of organisational commitment, which in turn significantly influenced customer-oriented prosocial behaviour. By stimulating nursing staff commitment, health care providers can urge them to pursue organisational goals and provide high quality customer service. To enhance organisational commitment, health care managers should endeavour to create interpersonal interaction platforms in addition to simply offering material rewards. Nurses act as contact employees for their patient customers in the hospital, and they are required to provide patient safety and service quality. This study shows that nurses with high organisational commitment are willing to provide customer-oriented prosocial activities, which in turn enhances patient satisfaction. © 2011 Blackwell Publishing Ltd.

  8. State Right to Refuse Medication Laws and Procedures: Impact on Homicide and Suicide.

    2016-09-01

    As part of the expansive overhaul of the mental health system that occurred in the latter half of the 20th Century, many states passed laws that allow, under certain conditions, voluntary and involuntarily committed patients to refuse medication. While some predicted the consequences of these laws would be dire, the effect on violent behavior remains untested. The aim is to decipher any differences state right to refuse medication laws may have on violence. Using the homicide rate of every US state between 1972 and 2001 (N = 1,479), and the suicide rate between 1981 and 2001 (N = 1,071). The study compares the difference in homicide/suicide rates before and after a law change to that same difference in a set of control states to estimate the effect of laws aimed at extending the right to refuse medication to both voluntary and involuntarily committed mental health patients. Laws designed to allow voluntarily committed patients to refuse medication are associated with a 0.8 increase in homicides per 100,000 of the state population while laws dictating an involuntarily committed patient's right to request refusal of medication are negative but statistically insignificant using standard t test. Laws designed to allow voluntarily committed patients to refuse medication have no statistically significant effect on suicides while laws dictating an involuntarily committed patient's right to request refusal of medication, specifically when the request is reviewed by independent mental health professionals, are associated with a statistically significant reduction in suicides. Allowing voluntarily committed patients to refuse medication may entice some to enter in-patient facilities, but the brief and optional exposure to medication and their side effects may actually discourage treatment and increase violence.

    In the past decade, "big push" global health initiatives financed by international donors have aimed to rapidly reach ambitious health targets in low-income countries. The health system impacts of these efforts are infrequently assessed. Saving Mothers, Giving Life is a global public-private partnership that aims to reduce maternal mortality dramatically in one year in eight districts in Uganda and Zambia. We evaluated the first six to twelve months of the program's implementation, its ownership by national ministries of health, and its effects on health systems. The project's impact on maternal mortality is not reported here. We found that the Saving Mothers, Giving Life initiative delivered a large "dose" of intervention quickly by capitalizing on existing US international health assistance platforms, such as the President's Emergency Plan for AIDS Relief. Early benefits to the broader health system included greater policy attention to maternal and child health, new health care infrastructure, and new models for collaborating with the private sector and communities. However, the rapid pace, external design, and lack of a long-term financing plan hindered integration into the health system and local ownership. Sustaining and scaling up early gains of similar big push initiatives requires longer-term commitments and a clear plan for transition to national control.

    Uranium (238U) and thorium (232Th) concentrations as well as radon (222Rn) and thoron (220Rn) alpha activities per unit volume have been measured inside 18 medical drugs (4 liquid and 14 solid materials), widely prescribed by doctors to the Moroccan adult patients, by using CR-39 and LR-115 type II solid state nuclear track detectors (SSNTDs). The measured 238U, 232Th, 222Rn, and 220Rn concentrations ranged from (4.7 +/- 0.1) mBq L-1 to (14.3 +/- 0.7) mBq L-1, (0.32 +/- 0.02) mBq L-1 to (2.7 +/- 0.2) mBq L-1, (4.7 +/- 0.2) Bq L-1 to (14.3 +/- 0.7) Bq L-1, and (0.32 +/- 0.02) Bq L-1 to (2.7 +/- 0.2) Bq L-1 for the medical drug samples studied, respectively. These radionuclides were also measured inside the preparations of the solid medical drugs studied. The influence of the drinking water nature and pollution on the concentrations of these radionuclides inside the considered medical drug preparations was investigated. Annual committed equivalent doses due to 238U, 232Th, and 222Rn were evaluated in the human body compartments of adult patients from the ingestion of the medical drug preparations studied. The maximum total committed effective dose due to 238U, 232Th, and 222Rn from the ingestion of the studied medical drug preparations, prepared from unpolluted waters, by adult patients was found equal to 1.44 microSv y.

    Recognizing their importance in the average Malaysian daily diet, the radioactivity concentrations in mollusc- and crustacean-based food have been determined for key naturally occuring radionuclides. Fresh samples collected from various maritime locations around peninsular Malaysia have been processed using standard procedures; the radionuclide concentrations being determined using an HPGe γ-ray spectrometer. For molluscs, assuming secular equilibrium, the range of activities of 238U (226Ra), 232Th (228Ra) and 40K were found to be 3.28±0.35 to 5.34±0.52, 1.20±0.21 to 2.44±0.21 and 118±6 to 281±14 Bq kg-1 dry weight, respectively. The respective values for crustaceans were 3.02±0.57 to 4.70±0.52, 1.38±0.21 to 2.40±0.35 and 216±11 to 316±15 Bq kg-1. The estimated average daily intake of radioactivity from consumption of molluscs are 0.37 Bq kg-1 for 238U (226Ra), 0.16 Bq kg-1 for 232Th (228Ra) and 18 Bq kg-1 for 40K; the respective daily intake values from crustaceans are 0.36 Bq kg-1, 0.16 Bq kg-1 and 23 Bq kg-1. Associated annual committed effective doses from molluscs are estimated to be in the range 21.3 to 34.7 μSv for 226Ra, 19.3 to 39.1 μSv for 228Ra and 17.0 to 40.4 μSv for 40K. For crustaceans, the respective dose ranges are 19.6 to 30.5 μSv, 22.0 to 38.4 μSv and 31.1 to 45.5 μSv, being some several times world average values.

    The United Nations Framework Convention on Climate Change, signed at Rio in June 1992, is intended to minimize climate change and its impact. Much of its text is ambiguous and it is not specifically directed to health considerations. It is, however, recognized that adverse effects of climate change on health are a concern of humankind, and health is an integral part of the Convention. The Convention includes commitments by the developed countries to reduce emissions of greenhouse gases and to increase public awareness of these commitments. The significance of the Convention in these respects is discussed critically and future developments considered.

  20. Operating health analysis of electric power systems

    NASA Astrophysics Data System (ADS)

    Fotuhi-Firuzabad, Mahmud

    The required level of operating reserve to be maintained by an electric power system can be determined using both deterministic and probabilistic techniques. Despite the obvious disadvantages of deterministic approaches there is still considerable reluctance to apply probabilistic techniques due to the difficulty of interpreting a single numerical risk index and the lack of sufficient information provided by a single index. A practical way to overcome difficulties is to embed deterministic considerations in the probabilistic indices in order to monitor the system well-being. The system well-being can be designated as healthy, marginal and at risk. The concept of system well-being is examined and extended in this thesis to cover the overall area of operating reserve assessment. Operating reserve evaluation involves the two distinctly different aspects of unit commitment and the dispatch of the committed units. Unit commitment health analysis involves the determination of which unit should be committed to satisfy the operating criteria. The concepts developed for unit commitment health, margin and risk are extended in this thesis to evaluate the response well-being of a generating system. A procedure is presented to determine the optimum dispatch of the committed units to satisfy the response criteria. The impact on the response wellbeing being of variations in the margin time, required regulating margin and load forecast uncertainty are illustrated. The effects on the response well-being of rapid start units, interruptible loads and postponable outages are also illustrated. System well-being is, in general, greatly improved by interconnection with other power systems. The well-being concepts are extended to evaluate the spinning reserve requirements in interconnected systems. The interconnected system unit commitment problem is decomposed into two subproblems in which unit scheduling is performed in each isolated system followed by interconnected system evaluation. A procedure is illustrated to determine the well-being indices of the overall interconnected system. Under normal operating conditions, the system may also be able to carry a limited amount of interruptible load on top of its firm load without violating the operating criterion. An energy based approach is presented to determine the optimum interruptible load carrying capability in both the isolated and interconnected systems. Composite system spinning reserve assessment and composite system well-being are also examined in this research work. The impacts on the composite well-being of operating reserve considerations such as stand-by units, interruptible loads and the physical locations of these resources are illustrated. It is expected that the well-being framework and the concepts developed in this research work will prove extremely useful in the new competitive utility environment.

    This study provides detailed information regarding the imaging doses to patient radiosensitive organs from a kilovoltage computed tomography (CT) scan procedure using OSLD. The study reports discrepancies between the measured dose and the calculated dose from the ImPACT scan, as well as a comparison with the dose from a chest X-ray radiography procedure. OSLDs were inserted in several organs, including the brain, eyes, thyroid, lung, heart, spinal cord, breast, spleen, stomach, liver and ovaries, of the RANDO phantom. Standard clinical scanning protocols were used for each individual site, including the brain, thyroid, lung, breast, stomach, liver and ovaries. The measured absorbed doses were then compared with the simulated dose obtained from the ImPACT scan. Additionally, the equivalent doses for each organ were calculated and compared with the dose from a chest X-ray radiography procedure. Absorbed organ doses measured by OSLD in the RANDO phantom of up to 17 mGy depend on the organ scanned and the scanning protocols used. A maximum 9.82% difference was observed between the target organ dose measured by OSLD and the results from the ImPACT scan. The maximum equivalent organ dose measured during this experiment was equal to 99.899 times the equivalent dose from a chest X-ray radiography procedure. The discrepancies between the measured dose with the OSLD and the calculated dose from the ImPACT scan were within 10%. This report recommends the use of OSLD for measuring the absorbed organ dose during CT examination.

    Despite the wealth of studies demonstrating the impairing effects of alcohol on behavioral inhibition, less is known regarding effects of the drug on attentional inhibition (i.e., the ability to ignore distracting stimuli in the environment in order to focus attention on relevant information). The current study examined alcohol impairment of both behavioral and attentional inhibition, as well as potential associations between the two mechanisms of inhibitory control. Men (n=27) and women (n=21) performed a measure of behavioral inhibition (cued go/no-go task) and a measure of attentional inhibition (delayed ocular return task) following three doses of alcohol: 0.65 g/kg, 0.45 g/kg, and 0.0 g/kg (placebo). Alcohol impaired both behavioral and attentional inhibition relative to placebo; however, correlational analyses revealed no associations between measures of behavioral and attentional inhibition following any dose. Additionally, men committed more inhibitory failures on the behavioral inhibition task, whereas women committed more inhibitory failures on the attentional inhibition task. These findings suggest that behavioral and attentional inhibition are equally sensitive to the impairing effects of alcohol, yet represent distinct components of inhibitory control. Additionally, the observed gender differences in control of behavior and attention could have important implications regarding negative consequences associated with alcohol-induced disinhibition in men and women.

    This study examined predictor, moderator, and mediator variables of occupational turnover intention (OcTI) among substance abuse counselors. Data were obtained via questionnaires from 929 counselors working in 225 private substance abuse treatment (SAT) programs across the U.S. Hierarchical multiple regression models were conducted to assess predictor, moderator, and mediator variables of OcTI. OcTI scores were relatively low on a 7-point scale, indicating that very few counselors definitely intended to leave the SAT field. Age, certification, positive perceptions of procedural and distributive justice, and hospital-based status negatively predicted OcTI. Counselors’ substance use disorder impacted history moderated the association between organizational commitment and OcTI. Organizational turnover intention partially mediated the link between organizational commitment and OcTI. Workforce stability might be achieved by promoting perceptions of advantages to working in a particular treatment program, organizational commitment, showing appreciation for counselors’ work, and valuing employees from diverse backgrounds.

    This paper describes how a school of nursing has conceptualized and embodied social responsibility in its core values, curricular design, admission standards, clinical practice, and service learning opportunities. The school's engagement in the process of practicing social responsibility and clarifying its meaning and application has made apparent the natural linkage between social responsibility and professionalism and the deep and complex relationship between social responsibility and nursing itself. It has also revealed how a commitment to social responsibility impacts and determines for whom nurses care. Claiming social responsibility as a core value and working to refine its meaning and place has increased the school's commitment to it, concomitantly impacting education, practice, and recruitment and evaluation of faculty and students. The school views the conceptualization of social responsibility as a deepening and unfolding evolution, rather than as a formulaic understanding, and expects that its ongoing work of claiming social responsibility as a core value will continue to be enriching.

  6. Does culture impact on notions of criminal responsibility and action? The case of spirit possession.

    Multicultural societies such as the United Kingdom are host to people with diverse belief systems and behavioral norms. Whilst a country requires that all members of society conform to standardized legal requirements, cases arise that involve certain complexities related to the cultural or religious context in which a certain action was committed. This paper addresses the impact of culture on notions of criminal responsibility and action. Through a case study of a recent event in the United Kingdom, we explore whether a cultural defense is relevant for contextualizing incidents in which an individual commits a criminal action during an alleged period of spirit possession From this analysis, we suggest that using a cultural defense can aid understanding of an individual's relationship to the society that he or she identifies with and facilitate the practice of justice in a multicultural society. © The Author(s) 2016.

    Some 7400 schools belong to the global network of UNESCO's Associated School Project Network. They are committed to promoting ideals such as human rights, intercultural understanding, peace and environmental protection. This study is based on an extensive review undertaken in 2003. It discusses the origins and analyzes the achievements of the Associated School Project Network in bringing change to schools, communities and national policy. The analysis employs a variety of models of educational innovation and reform in order to assess the horizontal and vertical impact of the Associated School Project Network. It draws general conclusions on the usefulness of such networks for intercultural learning and educational and social change. Key issues include the commitment of stakeholders; the treatment of culturally sensitive issues; cultural interpretations of certain subjects; the value of horizontal networks; and the difficulty of achieving vertical impact on national policy-making.

    CT neuroperfusion examinations are capable of delivering high radiation dose to the skin or lens of the eyes of a patient and can possibly cause deterministic radiation injury. The purpose of this study is to: (a) estimate peak skin dose and eye lens dose from CT neuroperfusion examinations based on several voxelized adult patient models of different head size and (b) investigate how well those doses can be approximated by some commonly used CT dose metrics or tools, such as CTDIvol, American Association of Physicists in Medicine (AAPM) Report No. 111 style peak dose measurements, and the ImPACT organ dose calculator spreadsheet. Monte Carlo simulation methods were used to estimate peak skin and eye lens dose on voxelized patient models, including GSF's Irene, Frank, Donna, and Golem, on four scanners from the major manufacturers at the widest collimation under all available tube potentials. Doses were reported on a per 100 mAs basis. CTDIvol measurements for a 16 cm CTDI phantom, AAPM Report No. 111 style peak dose measurements, and ImPACT calculations were performed for available scanners at all tube potentials. These were then compared with results from Monte Carlo simulations. The dose variations across the different voxelized patient models were small. Dependent on the tube potential and scanner and patient model, CTDIvol values overestimated peak skin dose by 26%-65%, and overestimated eye lens dose by 33%-106%, when compared to Monte Carlo simulations. AAPM Report No. 111 style measurements were much closer to peak skin estimates ranging from a 14% underestimate to a 33% overestimate, and with eye lens dose estimates ranging from a 9% underestimate to a 66% overestimate. The ImPACT spreadsheet overestimated eye lens dose by 2%-82% relative to voxelized model simulations. CTDIvol consistently overestimates dose to eye lens and skin. The ImPACT tool also overestimated dose to eye lenses. As such they are still useful as a conservative predictor of dose for CT neuroperfusion studies. AAPM Report No. 111 style measurements are a better predictor of both peak skin and eye lens dose than CTDIvol and ImPACT for the patient models used in this study. It should be remembered that both the AAPM Report No. 111 peak dose metric and CTDIvol dose metric are dose indices and were not intended to represent actual organ doses.

    Purpose: to successfully install a dose monitoring software (DMS) application to assist in CT protocol and dose management. Methods: Upon selecting the DMS, we began our implementation of the application. A working group composed of Medical Physics, Radiology Administration, Information Technology, and CT technologists was formed. On-site training in the application was supplied by the vendor. The decision was made to apply the process for all the CT protocols on all platforms at all facilities. Protocols were painstakingly mapped to the correct masters, and the system went ‘live’. Results: We are routinely using DMS as a tool in our Clinicalmore » Performance CT QA program. It is useful in determining the effectiveness of revisions to existing protocols, and establishing performance baselines for new units. However, the implementation was not without difficulty. We identified several pitfalls and obstacles which frustrated progress. Including: Training deficiencies, Nomenclature problems, Communication, DICOM variability. Conclusion: Dose monitoring software can be a potent tool for QA. However, implementation of the program can be problematic and requires planning, organization and commitment.« less

    Mechanic workers are exposed to exhaust fumes when controlling vehicle engines in motion inside repair shops. To assess radiation doses due to radon short-lived progeny from the inhalation of exhaust fumes by mechanic workers, concentrations of these radionuclides were measured in petrol (gasoline) and gas-oil exhaust fumes by evaluating mean critical angles of etching of the CR-39 and LR-115 type II SSNTDs for alpha particles emitted by the radon and thoron decay series. Committed effective doses due to ²¹⁸Po and ²¹⁴Po short-lived radon decay products from the inhalation of petrol and gas-oil exhaust fumes by workers were evaluated. A maximum value of 1.35 mSv y⁻¹ due to radon short-lived decay products from the inhalation of gas-oil exhaust fumes by mechanic workers was found, which is lower than the (3-10 mSv y⁻¹) dose limit interval for workers.

    The primary study objective was to assess radiation doses using a modified form of the Imaging Performance Assessment of Computed Tomography (CT) scanner (ImPACT) patient dosimetry for cardiac applications on an Aquilion ONE ViSION Edition scanner, including the Ca score, target computed tomography angiography (CTA), prospective CTA, continuous CTA/cardiac function analysis (CFA), and CTA/CFA modulation. Accordingly, we clarified the CT dose index (CTDI) to determine the relationship between heart rate (HR) and X‐ray exposure. As a secondary objective, we compared radiation doses using modified ImPACT, a whole‐body dosimetry phantom study, and the k‐factor method to verify the validity of the dose results obtained with modified ImPACT. The effective dose determined for the reference person (4.66 mSv at 60 beats per minute (bpm) and 33.43 mSv at 90 bpm) were approximately 10% less than those determined for the phantom study (5.28 mSv and 36.68 mSv). The effective doses according to the k‐factor (0.014 mSv·mGy−1·cm−1; 2.57 mSv and 17.10 mSv) were significantly lower than those obtained with the other two methods. In the present study, we have shown that ImPACT, when modified for cardiac applications, can assess both absorbed and effective doses. The results of our dose comparison indicate that modified ImPACT dose assessment is a promising and practical method for evaluating coronary CTA.

  13. From controlled to committed.

    1996-02-01

    Most of us agree that people are our most important resource. Yet we spend a minimal amount of time learning more about human behavior, communication, and how our attitudes and behavior impact employee performance. Instead we rely on traditional methods of negative reinforcement in an attempt to control our areas of responsibility. While these methods can render some short-term success, managers and organizations that succeed during these times of change and fierce competition will be those that take the time to understand and capture the power of a committed workforce. The committed workforce is energized, not simply compliant, as a result of having basic human needs for achievement satisfied, belonging to a group, and receiving recognition for its contributions. Committed workers typically describe the manager as one who has the ability to give them a great degree of control over their area of influence. We all know that we don't change our leadership style like we change clothes. Old habits die hard. it takes a personal commitment and lots of practice to rid outselves of habits and behavior that no longer serve our departments and facilities. This commitment, however, is crucial to survival. As managers, we must cope with increasing ambiguity and uncertainty in the workplace. To survive these challenges, we must improve our interpersonal skills and ability to successfully bring out the best in others. I believe that success will continue for managers who not only increase their knowledge and technical ability, but who also inspire their workers to move forward with a collective sense of enthusiasm and purpose.

    This article focuses on employee performance-management practices in the healthcare sector. We specifically aim to contribute to a better understanding of the impact of employee performance-management practices on affective well-being of nurses in hospitals. Theory suggests that the features of employee-performance management (planning and evaluation of individual performances) predict affective well-being (in this study: job satisfaction and affective commitment). Performance-management planning and evaluation and affective well-being were drawn from a survey of nurses at a Flemish hospital. Separate estimations were performed for different aspects of affective well-being. Performance planning has a negative effect on job satisfaction of nurses. Both vertical alignment and satisfaction with the employee performance-management system increase the affective well-being of nurses; however, the impact of vertical alignment differs for different aspects of affective well-being (i.e. job satisfaction and affective commitment). Performance-management planning and evaluation of nurses are associated with attitudinal outcomes. The results indicate that employee performance-management features have different impacts on different aspects of well-being. Copyright © 2014 Elsevier Ltd. All rights reserved.

    This article proposes a duplex theory for understanding the scientific impact of contributions to psychological science. I argue that articles that we "love" can be understood in terms of (a) triangular elements of intimacy, passion, and commitment and (b) types of stories that characterize high-impact articles. Certain kinds of stories (e.g., review articles) are more likely to have lasting impact, on average, than other kinds of stories (e.g., data-driven empirical articles).

    This paper is a report of a study to determine whether a favourable perception of internal marketing is associated with increased organizational commitment. The role of nurses in healthcare treatment is expanding, and becoming more important as time progresses. Therefore, the primary concern of business of health care is to use internal marketing strategies effectively to enhance and develop nurses' organizational commitment and reduce turnover to promote competitive advantages for the organization. A cross-sectional design was used. Questionnaires were distributed in 2006 to a convenience sample of 450 Registered Nurses in two teaching hospitals in Taiwan, and 318 questionnaires were returned. Eighteen were excluded because of incomplete answers, which left 300 usable questionnaires (response rate 66.7%). Validity and reliability testing of the questionnaire proved satisfactory and Structural Equation Modeling was used to analyse the data. A favourable perception of internal marketing was associated with increased organizational commitment. Communication management had the greatest influence on organizational commitment and external activity had the smallest impact. Hospital managers need to recognize the importance of internal marketing for staff retention and the survival of their organizations as competitive pressure increases. As a great deal of time and costs are involved in educating nurses, the best way to retain outstanding nurses and reduce turnover costs and personnel problems is for employers to understand the needs and expectations of their nursing staff.

  17. A model for the release, dispersion and environmental impact of a postulated reactor accident from a submerged commercial nuclear power plant

    Nuclear power plants are inherently suitable for submerged applications and could provide power to the shore power grid or support future underwater applications. The technology exists today and the construction of a submerged commercial nuclear power plant may become desirable. A submerged reactor is safer to humans because the infinite supply of water for heat removal, particulate retention in the water column, sedimentation to the ocean floor and inherent shielding of the aquatic environment would significantly mitigate the effects of a reactor accident. A better understanding of reactor operation in this new environment is required to quantify the radioecological impact and to determine the suitability of this concept. The impact of release to the environment from a severe reactor accident is a new aspect of the field of marine radioecology. Current efforts have been centered on radioecological impacts of nuclear waste disposal, nuclear weapons testing fallout and shore nuclear plant discharges. This dissertation examines the environmental impact of a severe reactor accident in a submerged commercial nuclear power plant, modeling a postulated site on the Atlantic continental shelf adjacent to the United States. This effort models the effects of geography, decay, particle transport/dispersion, bioaccumulation and elimination with associated dose commitment. The use of a source term equivalent to the release from Chernobyl allows comparison between the impacts of that accident and the postulated submerged commercial reactor plant accident. All input parameters are evaluated using sensitivity analysis. The effect of the release on marine biota is determined. Study of the pathways to humans from gaseous radionuclides, consumption of contaminated marine biota and direct exposure as contaminated water reaches the shoreline is conducted. The model developed by this effort predicts a significant mitigation of the radioecological impact of the reactor accident release with a submerged commercial nuclear power plant. The two box models predict the most of the radio-ecological impact occurs during the first eight days after release. The most significant risk to humans is from consumption of biota. The reduction in impact to humans from a large radioactive release makes the concept worthy of further study.

    The purpose of this paper is to identify factors influencing performance of hospital nurses in Riyadh Region, Saudi Arabia. Specific objectives were to estimate self-reported performance, and determine whether differences in employee demographics, job satisfaction, and organizational commitment, influenced performance. In total, 15 hospitals were randomly selected. The questionnaire was sent to all nurses (1,834) in these facilities and 923 nurses responded. Statistical analysis included correlation, t-test, and regression analysis. The study finds that job performance is positively correlated with organizational commitment, job satisfaction and personal and professional variables. Both job satisfaction and organizational commitment are strong predictors of nurses' performance. Job performance is positively related to some personal factors, including years of experience, nationality, gender, and marital status. Level of education is negatively related to performance. The findings of this study have a limited generalisability due to the fact that all measures used are based on self-reports. Future research may be directed to other objective measures of performance. Emphasis should be placed on effective supervision, empowerment, and a better reward system. Cultural diversity is a reality for most health organizations in Saudi Arabia; therefore, they need to adopt effective human resources strategies that aim to improve commitment and retention of qualified workers, and build a high performance organizational culture based on empowerment, open communication, and appreciation of impact of national culture on work attitudes. This study fulfills a research gap in the area of nursing performance, and its relationship with work attitudes in Saudi Arabia. The paper also highlights the impact of national culture on job performance and work attitude among nurses in Saudi Arabia, and other countries facing the issue of multi-national work force.

    This study aimed to assess the reliability and validity of the Chinese version of the Driver Aggression Indicators Scale (DAIS), which measures aggressive driving behaviors. Besides, demographic variables (sex and age) and the big five personality traits were examined as potential impact factors of aggressive driving. A total of 422 participants completed the DAIS, Big Five Personality Inventory (BFPI), and the socio-demographic scale. First, psychometric results confirmed that the DAIS had a stable two-factor structure and acceptable internal consistency. Then, agreeableness and conscientiousness were negatively correlated with hostile aggression and revenge committed by the drivers themselves, while neuroticism was positively correlated with aggressive driving committed by the drivers themselves. Meanwhile, more agreeable drivers may perceive less hostile aggression and revenge. More neurotic drivers may perceive more aggressive warning. Finally, the effects of age and sex on aggressive driving were not same as most studies. We found that older age group perceived and committed more hostile acts of aggression and revenge than younger age groups. Female drivers of 49-60 years perceived more aggressive warnings committed by other drivers. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Patient loyalty is key to business success for healthcare providers and also for patient health outcomes. This study aims to identify determinants influencing patient loyalty to healthcare providers and propose an integrative conceptual model of the influencing factors. PubMed, CINAHL, OVID, ProQuest and Elsevier Science Direct databases were searched. Publications about determinants of patient loyalty to health providers were screened, and 13 articles were included. Date of publication, location of the research, sample details, objectives and findings/conclusions were extracted for 13 articles. Thirteen studies explored eight determinants: satisfaction, quality, value, hospital brand image, trust, commitment, organizational citizenship behavior and customer complaints. The integrated conceptual model comprising all the determinants demonstrated the significant positive direct impact of quality on satisfaction and value, satisfaction on trust and commitment, trust on commitment and loyalty, and brand image on quality and loyalty. This review identifies and models the determinants of patient loyalty to healthcare providers. Further studies are needed to explore the influence of trust, commitment, and switching barriers on patient loyalty. © The Author 2017.

  5. Correlation between measles vaccine doses: implications for the maintenance of elimination.

    PubMed

    McKee, A; Ferrari, M J; Shea, K

    2018-03-01

    Measles eradication efforts have been successful at achieving elimination in many countries worldwide. Such countries actively work to maintain this elimination by continuing to improve coverage of two routine doses of measles vaccine following measles elimination. While improving measles vaccine coverage is always beneficial, we show, using a steady-state analysis of a dynamical model, that the correlation between populations receiving the first and second routine dose also has a significant impact on the population immunity achieved by a specified combination of first and second dose coverage. If the second dose is administered to people independently of whether they had the first dose, high second-dose coverage improves the proportion of the population receiving at least one dose, and will have a large effect on population immunity. If the second dose is administered only to people who have had the first dose, high second-dose coverage reduces the rate of primary vaccine failure, but does not reach people who missed the first dose; this will therefore have a relatively small effect on population immunity. When doses are administered dependently, and assuming the first dose has higher coverage, increasing the coverage of the first dose has a larger impact on population immunity than does increasing the coverage of the second. Correlation between vaccine doses has a significant impact on the level of population immunity maintained by current vaccination coverage, potentially outweighing the effects of age structure and, in some cases, recent improvements in vaccine coverage. It is therefore important to understand the correlation between vaccine doses as such correlation may have a large impact on the effectiveness of measles vaccination strategies.

    The model developed by a Task Group of Committee 2 of ICRP to describe Alkaline Earth Metabolism in Adult Man (ICRP Publication 20) has been modified so that recycling is handled explicitly, and retention in mineral bone is represented by second compartments rather than by the product of a power function and an exponential. This model has been extended to include all ages from birth to adult man, and has been coupled with modified "ICRP" lung and G.I. tract models so that activity in organs can be calculated as functions of time during or after exposures. These activities, and age dependent "specific effective energy" factors, are then used to calculate age dependent dose rates, and dose commitments. This presentation describes this work, with emphasis on the model parameters and results obtained for radium.

    The effects of the photosensitizers, PhotofrinTM and benozoporphyrin derivative monoacid ring A (BPD) on a variety of hematopoietic cell functions have been studied, both in the presence and absence of light activation. A marked increase in hematopoiesis was observed in the bone marrow and spleens of DBA/2 mice administered high dose Photofrin but not BPD. This was manifested in an increased relative spleen weight, nucleated spleen cell number and circulating white blood cell concentration 7 days following Photofrin injection. We have shown that BPD and light doses just below phototoxic ranges stimulate the growth of human colony forming committed myeloid progenitors as well as pluripotent stem cells grown in long term marrow culture. Studies on the effect of BPD on the function of T lymphocytes in the absence of light has also demonstrated a stimulatory effect. The dose range in which this is observed is considerably broader than that observed with light activation. The mechanisms involved in this stimulatory effect have been studied and are discussed.

    Potential environmental consequences in terms of radiation dose to people are presented for postulated accidents due to earthquakes, tornadoes, high straight-line winds, and floods. Maximum plutonium deposition values are given for significant locations around the site. All important potential exposure pathways are examined. The most likely calculated 50-year collective committed dose equivalents are all much lower than the collective dose equivalent expected from 50 years of exposure to natural background radiation and medical x-rays except Earthquake No. 4 and the 260-mph tornado. The most likely maximum residual plutonium contamination estimated to be deposited offsite following Earthquake No. 4, and themore » 200-mph and 260-mph tornadoes are above the Environmental Protection Agency's (EPA) proposed guideline for plutonium in the general environment of 0.2 ..mu..Ci/m/sup 2/.

    This research was dedicated to the study, in the Italian daily diet, of the background activity concentration of (210)Po, a radionuclide with a high radiotoxicity. (210)Po was determined by alpha spectrometry. For food products of vegetable origin, the (210)Po activity concentration follows the trend: leafy vegetable>flour>rice>fruits>pasta>other vegetables>fruit vegetable; for those of animal origin: eggs>cheese>milk. The (210)Po activity concentration was also compared with that found by the same authors in meat, sea food, water and beverages in a previous study. The committed effective doses to individuals of three population groups (infants, children and adults) were 379, 222 and 151 μSv y(-1), respectively. The intake of foods of marine origin contributed about 67% of the total dose due to (210)Po ingestion. The effective dose, from (210)Po ingested by total diet, accounts for only 5-12% of the natural radiation exposure in Italy. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Vegetable is an essential daily diet item for the people of Malaysia. This work addressed the radiation and heavy metal exposure scenarios through the consumption of vegetables. Kuala Selangor is located in Sungai Selangor estuary in the west coast of Peninsular Malaysia, which is susceptible to pollution load due to the presence of large-scale industrial and human activities. Radioactivity and heavy metals level in human diet is of particular concern for the assessment of possible radiological and chemical hazards to human health. Therefore, a comprehensive study was carried out to determine the radioactivity levels ((226)Ra, (228)Ra and (40)K) and heavy metal concentrations (Cr, As, Cd, Mn, Mg, Al, Sr, Rb, Sb, Ba, Hg, Fe, Ni, Zn, Cu, Bi and Pb) in 10 varieties of vegetable collected from different farmlands in Kuala Selangor region. The committed doses for (226)Ra, (228)Ra and (40)K due to consumption of vegetables were found 16.6±1.3, 23.6±1.7 and 58±5 µSv y(-1), respectively, with a total of 98±8 µSv y(-1). This dose imposes no significant threat to human health. The estimated cancer risk shows that probability of increase in cancer risk from daily intake of vegetables is only a minor fraction of International Commission on Radiological Protection values. The concentrations of heavy metal were below the daily intake recommended by the international organisations. © The Author 2015. Published by Oxford University Press. All rights reserved.

    Nationally, the number of internal medicine physicians practicing in primary care has decreased amidst increasing interest in hospitalist medicine. Current priorities in the Military Health System include access to primary care and retention of trained personnel. Recently, we have conducted a study of military internal medicine residents' decision to enter infectious disease. As part of our larger effort, we saw an opportunity to characterize factors impacting decision making of internal medicine residents' desire to apply for subspecialty training and to extend active duty service obligations. Questions were developed after discussion with various military graduate medical education and internal medicine leaders, underwent external review, and were added to a larger question set. The survey link was distributed electronically to all U.S. military affiliated residencies' graduating internal medicine residents in December 2016-January 2017. Data were analyzed by decision to apply to fellowship and decision to extend military obligation using Fisher's exact test or Pearon's chi-square test. Sixty-eight residents from 10 of 11 military residency programs responded, for a response rate of 51%. The majority (62%) applied to fellowship to start after residency completion. Reasons cited for applying to fellowship included wanting to become a specialist as soon as possible (74%), wishing to avoid being a general internist (57%), and because they are unable to practice as a hospitalist in the military (52%). Fellowship applicants were more likely to plan to extend their military obligation than non-applicants, as did those with longer duration of military commitments. No other factors, including Uniformed Services University attendance or participation in undergraduate military experiences, were found to impact plan to extend active duty service commitment. The majority of graduating internal medicine residents apply for fellowship and report a desire to avoid being a general internist. Prospective fellows anticipate extending their active duty commitment, as do those with longer commitments.

  15. Committed CO2 Emissions of China's Coal-fired Power Plants

    NASA Astrophysics Data System (ADS)

    Suqin, J.

    2016-12-01

    The extent of global warming is determined by the cumulative effects of CO2 in the atmosphere. Coal-fired power plants, the largest anthropogenic source of CO2 emissions, produce large amount of CO2 emissions during their lifetimes of operation (committed emissions), which thus influence the future carbon emission space under specific targets on mitigating climate change (e.g., the 2 degree warming limit relative to pre-industrial levels). Comprehensive understanding of committed CO2 emissions for coal-fired power generators is urgently needed in mitigating global climate change, especially in China, the largest global CO2emitter. We calculated China's committed CO2 emissions from coal-fired power generators installed during 1993-2013 and evaluated their impact on future emission spaces at the provincial level, by using local specific data on the newly installed capacities. The committed CO2 emissions are calculated as the product of the annual coal consumption from newly installed capacities, emission factors (CO2emissions per unit crude coal consumption) and expected lifetimes. The sensitivities about generators lifetimes and the drivers on provincial committed emissions are also analyzed. Our results show that these relatively recently installed coal-fired power generators will lead to 106 Gt of CO2 emissions over the course of their lifetimes, which is more than three times the global CO2 emissions from fossil fuels in 2010. More than 80% (85 Gt) of their total committed CO2 will be emitted after 2013, which are referred to as the remaining emissions. Due to the uncertainties of generators lifetime, these remaining emissions would increase by 45 Gt if the lifetimes of China's coal-fired power generators were prolonged by 15 years. Furthermore, the remaining emissions are very different among various provinces owing to local developments and policy disparities. Provinces with large amounts of secondary industry and abundant coal reserves have higher committed emissions. The national and provincial CO2 emission mitigation objectives might be greatly restricted by existing and planned power plants in China. The policy implications of our results have also been discussed.

    2016-10-01

    In Polish underground mines, hazards caused by enhanced natural radioactivity occur. The sources of radiation exposure are short-lived radon decay products, mine waters containing radium 226 Ra and 228 Ra and the radioactive sediments that can precipitate out of these waters. For miners, the greatest exposure is usually due to short-lived radon decay products. The risk assessment is based on the measurement of the total potential alpha energy concentration (PAEC) and the evaluation of the related dose by using the dose conversion factor as recommended by relevant legal requirements. This paper presents the results of measurements of particle size distributions of ambient aerosols in an underground hard coal mine, the assessment of the radioactive particle size distribution of the short-lived radon decay products and the corresponding values of dose conversion factors. The measurements of the ambient airborne particle size distribution were performed in the range from a few nanometers to about 20 μm. The study therefore included practically the whole class of respirable particles. The results showed that the high concentration of ultrafine and fine aerosols measured can significantly affect the value of the dose conversion factors, and consequently the corresponding committed effective dose, to which the miners can be exposed.

    An increasing number of health service sectors have begun to implement relationship marketing to try to establish long-term relationship with customers. Customer relational benefit has been an important subject for relationship marketing researchers. This study was conducted to investigate how customer relational benefit might influence relationship commitment in health service sectors. The research used a questionnaire survey that retrieved a total number of 403 valid questionnaires. The data were collected by way of personal visits and investigations of outpatients in three regional hospitals in Taiwan. After the reliability and the validity of the questionnaire sample were examined, the data were verified by using hierarchical regression analysis. Results showed that confidence benefit constituted the most pronounced factor for hospital customers. Confidence benefit, social benefit, and special treatment benefit were perceived by customers as the key factors that have a positive influence on relationship commitment. In particular, customers placing greater emphasis on confidence benefit tended to be less willing to establish relationship commitment. When health service managers develop marketing strategies using customer relational benefit, they will still need to enhance customer confidence benefit as one of the main ways of achieving future improvements. In the event where health service managers seek to install resources for establishing and maintaining a good relationship commitment with customers, the crucial factors of social and special treatment benefits should not be ignored when seeking to enhance the customers' perception of confidence benefit.

    Professionals in chiropractic education retain much of the authority over their work. Their work is impacted, negatively or positively, by their perceptions of their organization's value for their skills and knowledge. Specifically, empowerment and organizational commitment are 2 psychological constructs that may mediate work circumstances and therefore are the focus of this study. The purpose of this study is to explore associations between empowerment and organizational commitment among chiropractic faculty. Study design Full faculty survey utilizing descriptive statistics and multivariable analysis. Surveys were distributed to full- and part-time faculty working in the United States and Canada. The survey included Spreitzer's multidimensional measure of psychological empowerment, Meyer and Allen's multidimensional measure of organizational commitment, and additional survey items focusing on faculty demographics and workplace variables including sex, age, academic rank, employment status, and primary area of work assignment. More than 54% of the study population (N = 609) completed and returned the instrument. A general profile of a chiropractic faculty member emerges as a middle-aged male employed full-time as a teacher in the academic program. Regression analyses suggest that the observed faculty characteristics and the workplace variables are not associated with fit between the faculty member's work role and his/her own beliefs, norms, and behaviors regarding the value of the work-related tasks. The level of institutional commitment experienced by the faculty member was associated with the fit between the task, goal or purpose of the job, and the internal standards held by the individual.

  6. Effects of internal marketing on nurse job satisfaction and organizational commitment: example of medical centers in Southern Taiwan.

    2007-12-01

    As nurses typically represent the largest percentage of employees at medical centers, their role in medical care is exceptionally important and becoming more so over time. The quality and functions of nurses impact greatly on medical care quality. The concept of internal marketing, with origins in the field of market research, argues that enterprises should value and respect their employees by treating them as internal customers. Such a marketing concept challenges traditional marketing methods, which focus on serving external customers only. The main objective of internal marketing is to help internal customers (employees) gain greater job satisfaction, which should promote job performance and facilitate the organization accomplishing its ultimate business objectives. A question in the medical service industry is whether internal marketing can similarly increase the job satisfaction of nurses and enhance their commitment to the organization. This study aimed to explore the relational model of nurse perceptions related to internal marketing, job satisfaction, and organizational commitment by choosing nurses from two medical centers in Southern Taiwan as research subjects. Of 450 questionnaire distributed, 300 valid questionnaires were returned, giving a response rate of 66.7%. After conducting statistical analysis and estimation using structural equation modeling, findings included: (1) job satisfaction has positive effects on organizational commitment; (2) nurse perceptions of internal marketing have positive effects on job satisfaction; and (3) nurse perceptions of internal marketing have positive effects on organizational commitment.

    A total of 105 countries have introduced IPV as of September 2016 of which 85 have procured the vaccine through UNICEF. The Global Eradication and Endgame Strategic Plan 2013-2018 called for the rapid introduction of at least one dose of IPV into routine immunization schedules in 126 all OPV-using countries by the end of 2015. At the time of initiating the procurement process, demand was estimated based on global modeling rather than individual country indications. In its capacity as procurement agency for the Global Polio Eradication Initiative and Gavi, the Vaccine Alliance, UNICEF set out to secure access to IPV supply for around 100 countries. Based on offers received, sufficient supply was awarded to two manufacturers to meet projected routine requirements. However, due to technical issues scaling up vaccine production and an unforecasted demand for IPV use in campaigns to interrupt wild polio virus and to control type 2 vaccine derived polio virus outbreaks, IPV supplies are severely constrained. Activities to stretch supplies and to suppress demand have been ongoing since 2014, including delaying IPV introduction in countries where risks of type 2 reintroduction are lower, implementing the multi-dose vial policy, and encouraging the use of fractional dose delivered intradermally. Despite these efforts, there is still insufficient IPV supply to meet demand. The impact of the supply situation on IPV introduction timelines in countries are the focus of this article, and based on lessons learned with the IPV introductions, it is recommended for future health programs with accelerated scale up of programs, to take a cautious approach on supply commitments, putting in place clear allocation criteria in case of shortages or delays and establishing a communication strategy vis a vis beneficiaries. © The Author 2017.

    Quiescence, self-renewal, lineage commitment and differentiation of hematopoietic stem cells (HSCs) towards fully mature blood cells are a complex process that involves both intrinsic and extrinsic signals. During steady-state conditions, most hematopoietic signals are provided by various resident cells inside the bone marrow (BM), which establish the HSC micro-environment. However, upon infection, the hematopoietic process is also affected by pathogens and activated immune cells, which illustrates an effective feedback mechanism to hematopoietic stem and progenitor cells (HSPCs) via immune-mediated signals. Here, we review the impact of pathogen-associated molecular patterns (PAMPs), damage-associated molecular patterns (DAMPs), costimulatory molecules and pro-inflammatory cytokines onmore » the quiescence, proliferation and differentiation of HSCs and more committed progenitors. As modulation of HSPC function via these immune-mediated signals holds an interesting parallel with the “three-signal-model” described for the activation and differentiation of naïve T-cells, we propose a novel “three-signal” concept for immune-driven hematopoiesis. In this model, the recognition of PAMPs and DAMPs will activate HSCs and induce proliferation, while costimulatory molecules and pro-inflammatory cytokines confer a second and third signal, respectively, which further regulate expansion, lineage commitment and differentiation of HSPCs. We review the impact of inflammatory stress on hematopoiesis along these three signals and we discuss whether they act independently from each other or that concurrence of these signals is important for an adequate response of HSPCs upon infection. - Highlights: • Inflammation and infection have a direct impact on hematopoiesis in the bone marrow. • We draw a striking parallel between immune-driven hematopoiesis and T cell activation. • We review how PAMPs and DAMPs, costimulation and cytokines influence HSPC function.« less

    Organisational change occurs when an organisation makes a transition from its current state to some desired future state in minimising employee resistance and cost to the organisation while simultaneously maximising the effectiveness of the change effort. This paper, aims at appraising the change management of organisation in Malaysia since limited research has been done to examine readiness for change by the employees in the organisation. This paper is materialising its objectives of (1) investigating the current practice of organisation and employees in the organisation towards change management and (2) assessing the factors influencing readiness of organisation and employees in the organisation towards change management. It is found via literature review that change management is a structured approach for ensuring that changes are thoroughly and smoothly implemented to transitioning individuals, teams, and organisations to a desired future state by focusing on the wider impacts of change, particularly on people, where change does not happen in isolation and it impacts the whole organisation. Furthermore, it is found that current practice of organisation and employees in the organisation towards change management involved in three main factors, namely trust in management, communication and organisational commitment; with the factor for trust in management is the positive vision for the future by management team, meanwhile for communication, it is found that there is good communication between supervisors and employees about the organisation's policy toward the changes. The factor found in organisational commitment is employees enjoying discussing about their organisation with outsiders. The findings of this paper provide a positive impact on change management planning, which ultimately help in ensuring more effective change programme implementation in the organisation in Malaysia.

    To elucidate the impacts of nuclear plant accidents on neighboring medical centers, we investigated the operations of our hospital within the first 10 days of the Great East Japan Earthquake followed by the Fukushima Daiichi nuclear power plant accident. Data were extracted from medical records and hospital administrative records covering 11 to 20 March 2011. Factual information on the disaster was obtained from public access media. A total of 622 outpatients and 241 inpatients were treated. Outpatients included 43 injured, 6 with cardiopulmonary arrest, and 573 with chronic diseases. Among the 241 inpatients, 5 died, 137 were discharged, and the other 99 were transferred to other hospitals. No communication methods or medical or food supplies were available for 4 days after the earthquake. Hospital directors allowed employees to leave the hospital on day 4. All 39 temporary workers were evacuated immediately, and 71 of 239 full-time employees remained. These employees handled extra tasks besides patient care and patient transfer to other hospitals. Committed effective doses indicating the magnitude of health risks due to an intake of radioactive cesium into the human body were found to be minimal according to internal radiation exposure screening carried out from July to August 2011. After the disaster, hospitals located within the evacuation zone of a 30-km radius of the nuclear power plant were isolated. Maintenance of the health care system in such an event becomes difficult.

  11. When Action-Inaction Framing Leads to Higher Escalation of Commitment: A New Inaction-Effect Perspective on the Sunk-Cost Fallacy.

    2018-04-01

    Escalation of commitment to a failing course of action occurs in the presence of (a) sunk costs, (b) negative feedback that things are deviating from expectations, and (c) a decision between escalation and de-escalation. Most of the literature to date has focused on sunk costs, yet we offer a new perspective on the classic escalation-of-commitment phenomenon by focusing on the impact of negative feedback. On the basis of the inaction-effect bias, we theorized that negative feedback results in the tendency to take action, regardless of what that action may be. In four experiments, we demonstrated that people facing escalation-decision situations were indeed action oriented and that framing escalation as action and de-escalation as inaction resulted in a stronger tendency to escalate than framing de-escalation as action and escalation as inaction (mini-meta-analysis effect d = 0.37, 95% confidence interval = [0.21, 0.53]).

    There has been a long discussion among historians about the impact that foundation policies had on the development of the social sciences during the interwar era. This discussion has centered on the degree to which foundation officers, particularly from the Rockefeller boards, exercised a hegemonic influence on research. In this essay, I argue that the field of American cultural anthropology has been neglected and must be reconsidered as a window into foundation intervention in nature-nurture debates. Despite foundation efforts to craft an anthropology policy that privileged hereditarian explanations, I contend that cultural anthropologists were committed to proving the primacy of "nurture," even when that commitment cost them valuable research dollars. It was this commitment that provided an essential bulwark for the discipline. Ironically, it was the need to negotiate with foundations about the purpose of their research that helped cultural anthropologists to articulate their unique, and thus intrinsically valuable, approach to nature-nurture debates.

  13. 241Am Ingrowth and Its Effect on Internal Dose

    Generally, plutonium has been manufactured to support commercial and military applications involving heat sources, weapons and reactor fuel. This work focuses on three typical plutonium mixtures, while observing the potential of 241Am ingrowth and its effect on internal dose. The term “ingrowth” is used to describe 241Am production due solely from the decay of 241Pu as part of a plutonium mixture, where it is initially absent or present in a smaller quantity. Dose calculation models do not account for 241Am ingrowth unless the 241Pu quantity is specified. This work suggested that 241Am ingrowth be considered in bioassay analysis when theremore » is a potential of a 10% increase to the individual’s committed effective dose. It was determined that plutonium fuel mixtures, initially absent of 241Am, would likely exceed 10% for typical reactor grade fuel aged less than 30 years; however, heat source grade and aged weapons grade fuel would normally fall below this threshold. In conclusion, although this work addresses typical plutonium mixtures following separation, it may be extended to irradiated commercial uranium fuel and is expected to be a concern in the recycling of spent fuel.« less

    Kennedy, W.E. Jr.; Watson, E.C.

    Radiation protection regulations in the United States have evolved from the recommendations of the International Commission on Radiological Protection (ICRP) and the National Council on Radiation Protection and Measurements (NCRP). In 1959, the ICRP issued Publication 2 which contained specific recommendations on dose rate limits, permissible body burdens, metabolic data for radionuclides, and maximum permissible concentrations (MPC) in air or water. Over the next 20 years, new information became available concerning the effects of radiation, the uptake and retention of radionuclides, and the radioactive decay schemes of parent radionuclides. To include this newer information, the ICRP issued Publication 30 inmore » 1978 to supersede Publication 2. One of the secondary limits defined in Publication 30 is the annual limit of intake (ALI). Radionuclide specific ALI values are intended to replace MPC values in determining whether or not ambient air and water concentrations are sufficiently low to maintain the dose to workers within accepted dose rate limits. In this paper, we discuss the derivation of MPC and ALI values, compare inhalation committed dose equivalent factors derived from ICRP Publications 2 and 30, and discuss the practical implications of using either MPC or ALI in determining compliance with occupational exposure limits. 6 references.« less

    In this article natural radioactivity measurements and dosimetric evaluations in soil samples contaminated by Naturally Occurring Radioactive Materials (NORM) are made, in order to assess any possible radiological hazard for the population and for workers professionally exposed to ionizing radiations. Investigated samples came from the district of Crotone, Calabria region, South of Italy. The natural radioactivity investigation was performed by high-resolution gamma-ray spectrometry. From the measured gamma spectra, activity concentrations were determined for 226Ra , 234-mPa , 224Ra , 228Ac and 40K and compared with their clearance levels for NORM. The total effective dose was calculated for each sample as due to the committed effective dose for inhalation and to the effective dose from external irradiation. The sum of the total effective doses estimated for all investigated samples was compared to the action levels provided by the Italian legislation (D.Lgs.230/95 and subsequent modifications) for the population members (0.3mSv/y) and for professionally exposed workers (1mSv/y). It was found to be less than the limit of no radiological significance (10μSv/y).

  3. A Racial Equity Toolkit for Midwifery Organizations.

    PubMed

    Gordon, Wendy M

    2016-11-01

    Midwifery associations are increasing awareness and commitment to racial equity in the profession and in the communities we serve. Moving these commitments from words into action may be facilitated by a racial equity toolkit to help guide midwifery organizations to consider all policies, initiatives, and actions with a racial equity lens. Racial equity impact analyses have been used in recent years by various governmental agencies in the United States and abroad with positive results, and emerging literature indicates that nonprofit organizations are having similarly positive results. This article proposes a framework for midwifery organizations to incorporate a racial equity toolkit, starting with explicit intentions of the organization with regard to racial equity in the profession. Indicators of success are elucidated as the next step, followed by the use of a racial equity impact analysis worksheet. This worksheet is applied by teams or committees when considering new policies or initiatives to examine those actions through a racial equity lens. An organizational change team and equity advisory groups are essential in assisting organizational leadership to forecast potential negative and positive impacts. Examples of the components of a midwifery-specific racial equity toolkit are included. © 2016 by the American College of Nurse-Midwives.

  4. The impact of prior knowledge from participant instructions in a mock crime P300 Concealed Information Test.

    2014-12-01

    In P300-Concealed Information Tests used with mock crime scenarios, the amount of detail revealed to a participant prior to the commission of the mock crime can have a serious impact on a study's validity. We predicted that exposure to crime details through instructions would bias detection rates toward enhanced sensitivity. In a 2 × 2 factorial design, participants were either informed (through mock crime instructions) or naïve as to the identity of a to-be-stolen item, and then either committed (guilty) or did not commit (innocent) the crime. Results showed that prior knowledge of the stolen item was sufficient to cause 69% of innocent-informed participants to be incorrectly classified as guilty. Further, we found a trend toward enhanced detection rate for guilty-informed participants over guilty-naïve participants. Results suggest that revealing details to participants through instructions biases detection rates in the P300-CIT toward enhanced sensitivity. Copyright © 2014 Elsevier B.V. All rights reserved.

  5. Inspecting the Dangers of Feeling like a Fake: An Empirical Investigation of the Impostor Phenomenon in the World of Work

    Neureiter, Mirjam; Traut-Mattausch, Eva

    2016-01-01

    To investigate the link between the impostor phenomenon (IP), career self-management (CSM) factors, and work-relevant outcomes, we looked at the IP's impact on career optimism, career adaptability, and knowledge of the job market, as well as on employee- and organizationally-relevant outcomes. We analyzed data from 238 working professionals (57% female) using parallel multiple mediation analyses. The results revealed that the IP was negatively related to all work-relevant outcomes through decreased CSM factors, which were subsequently associated with the outcomes. As hypothesized, employee-relevant subjective outcomes were mediated by optimism and employee-relevant objective (i.e., economic) outcomes by adaptability and knowledge. Additional mediating effects occurred. Regarding organizationally relevant outcomes, adaptability mediated the IP's impact on organizational citizenship behavior. The IP was only indirectly related to continuance commitment through adaptability and to affective commitment through optimism. We discuss the theoretical and practical implications and offer ideas for future research. PMID:27729882

  10. Sense or Sensibility?: How Commitment Mediates the Role of Self-Service Technology on Loyalty

    NASA Astrophysics Data System (ADS)

    Singh, Sangeeta; Olsen, Line Lervik

    It has been well documented that employing self-service technology (SST) results in considerable cost savings but few studies have examined its impact on consumers’ behavior. We apply a well-recognized model from the field of services marketing in an SST context. We examine how the established relationships between satisfaction, affective and calculative commitments, and loyalty are affected when the service is provided through a technology interface as opposed to service personnel. We then present two alternative perspectives on the role of SST. The first is based on the predominant assumption that SST is a moderator of the relationship between customer loyalty and its drivers, while the other rests on the assumption that SST is just another context and that its role in affecting customer loyalty is mediated by drivers of loyalty. A cross-sectional study conducted in the banking industry shows that SST does not change everything. The classical model of how customers evaluate services and the predictors of loyalty are replicated in the SST setting. Interestingly, SST does not have a direct influence on loyalty by itself but its effects are mediated by commitment. However, it is the affective commitment that is more important in forming loyalty toward the service provider.

    To explore staff perceptions about sustainability, commitment to change, participation in change process, and information received about the change project within the Veterans Administration Primary Care and Mental Health Integration (PC-MHI) initiative and to examine differences from the Veterans Health Administration Mental Health Systems Redesign (MHSR) initiative. Surveys of change team members involved in the Veterans Affairs PC-MHI and MHSR initiatives. One-way analysis of variance examined the relationship between commitment, participation and information, and sustainability. Differences in PC-MHI sustainability were explored by location and job classification. Staff sustainability perceptions were compared with MHSR results. Sustainability differed by staff discipline. Difference between MHSR and PC-MHI existed by job function and perceptions about the change benefits. Participation in the change process and information received about the change process were positively correlated with sustainability. Staff commitment to change was positively associated with staff perceptions about the benefits of change and staff attitudes toward change. Sustainability is an important part of organizational change efforts. Change complexity seems to influence perception about sustainability and impacts staff perceptions about the benefits of change. These perceptions seem to be driven by the information received and opportunities to participate in the change process. Further research is needed to understand how information and participation influence sustainability and affect employee commitment to change.

    2010-08-01

    Health services have increasingly proven to be an innovative sector, gaining prominence in the medical industrial complex through expansion to public and international markets. International trade can foster economic development and redirect the resources and infrastructure available for healthcare in different countries in favorable or unfavorable directions. Wherever private providers play a significant role in government-funded healthcare, GATS commitments may restrict health policy options in subscribing countries. Systematic information on the impacts of electronic health services, medical tourism, health workers' migration, and foreign direct investment is needed on a case-by-case basis to build evidence for informed decision-making, so as to maximize opportunities and minimize risks of GATS commitments.

    Religion is a powerful force in many people's lives, impacting decisions about life, death, and everything in between. It may be difficult, then, to imagine that something as seemingly innocuous as the usage of brand name products might influence individuals' commitment to religion. However, we demonstrate across 6 studies that when brands are a highly salient tool for self-expression, individuals are less likely to report and demonstrate strong religious commitment. We suggest that a desire to maintain consistency among self-identities is one important driver of this relationship and find that the effect is mitigated when the perceived distance between brands and religious values is minimized.

    1999-09-30

    A radiological assessment has been carried out considering discharges of radioactivity to the Baltic Sea marine environment since 1950. The sources of radioactivity that have been evaluated are atmospheric nuclear-weapons fallout, fallout from the Chernobyl accident in 1986, discharges of radionuclides from Sellafield and La Hague transported into the Baltic Sea, and discharges of radionuclides from nuclear installations located in the Baltic Sea area. Dose rates from man-made radioactivity to individual members of the public (critical groups) have been calculated based on annual intake of seafood and beach occupancy time. The dose rates to individuals from the regions of the Bothnian Sea and Gulf of Finland are predicted to be larger than from any other area in the Baltic Sea due to the pattern of Chernobyl fallout. The dose rates are predicted to have peaked in 1986 at a value of 0.2 mSv year-1. Collective committed doses to members of the public have been calculated based on fishery statistics and predicted concentrations of radionuclides in biota and coastal sediments. The total collective dose from man-made radioactivity in the Baltic Sea is estimated at 2600 manSv, of which approximately two-thirds originate from Chernobyl fallout, approximately one-quarter from atmospheric nuclear-weapons fallout, approximately 8% from European reprocessing facilities, and approximately 0.04% from nuclear installations bordering the Baltic Sea area. An assessment of small-scale dumping of low-level radioactive waste in the Baltic Sea in the 1960s by Sweden and the Soviet Union has showed that doses to man from these activities are negligible. Dose rates and doses from natural radioactivity dominate except for the year 1986 where dose rates to individuals from Chernobyl fallout in some regions of the Baltic Sea approached those from natural radioactivity.

    The radionuclides 137Cs, 134Cs and 90Sr have been measured in edible tissues and bones of migratory birds (song-thrushes, Turdus philomelos) from central and northern Europe and captured in the Comunidad Valenciana, Spain in the 1994 autumn-winter season. Eight years after the Chernobyl accident, extensive agricultural lands in Europe are still contaminated and this study shows that there was a transfer of radioactive isotopes to the captured migratory song-thrushes. The whole-body dose commitment to humans consuming these birds is estimated.

  3. Preferred providers and the credible commitment problem in health insurance: first experiences with the implementation of managed competition in the Dutch health care system.

    PubMed

    Boonen, Lieke H H M; Schut, Frederik T

    2011-04-01

    We investigate the impact of the transition towards managed competition in the Dutch health care system on health insurers' contracting behaviour. Specifically, we examine whether insurers have been able to take up their role as prudent buyers of care and examine consumers' attitudes towards insurers' new role. Health insurers' contracting behaviour is investigated by an extensive analysis of available information on purchasing practices by health insurers and by interviews with directors of health care purchasing of the four major health insurers, accounting for 90% of the market. Consumer attitudes towards insurers' new role are investigated by surveys among a representative sample of enrollees over the period 2005-2009. During the first four years of the reform, health insurers were very reluctant to engage in selective contracting and preferred to use 'soft' positive incentives to encourage preferred provider choice rather than engaging in restrictive managed care activities. Consumer attitudes towards channelling vary considerably by type of provider but generally became more negative in the first two years after the reform. Insurers' reluctance to use selective contracting can be at least partly explained by the presence of a credible-commitment problem. Consumers do not trust that insurers with restrictive networks are committed to provide good quality care. The credible-commitment problem seems to be particularly relevant to the Netherlands, since Dutch enrollees are not used to restrictions on provider choice. Since consumers are quite sensitive to differences in provider quality, more reliable information about provider quality is required to reduce the credible-commitment problem.

    Self esteem (SE) and organizational commitment (OC)? have significant impact on the quality of work life. This study aims to gain a better understanding of the relationships between SE and OC among health information management staff in tertiary care hospitals in Tehran (Iran). This was a descriptive correlational and cross sectional study conducted on the health information management staff of tertiary care hospitals in Tehran, Iran. A total of 155 participants were randomly selected from 400 staff. Data were collected by two standard questionnaires. The SE and OC was measured using Eysenck SE scale and Meyer and Allen's three component model, respectively. The collected data were analyzed with the SPSS (version 16) using statistical tests of of independent T-test, Pearson Correlation coefficient, one way ANOVA and F tests. The OC and SE of the employees' were 67.8?, out of 120 (weak) and 21.0 out of 30 (moderate), respectively. The values for affective commitment, normative commitment, and continuance commitment were respectively 21.3 out of 40 (moderate), 23.9 out of 40 (moderate), and 22.7 out of 40 (moderate). The Pearson correlation coefficient test showed a significant OC and SE was statistically significant (P<0.05). The one way ANOVA test (P<0.05) did not show any significant difference between educational degree and work experience with SE and OC. This research showed that SE and OC ?are moderate. SE and OC have strong correlation with turnover, critical thinking, job satisfaction, and individual and organizational improvement. Therefore, applying appropriate human resource policies is crucial to reinforce these measures.

    2018-04-01

    To increase understanding of the relationships between organisational justice, affective commitment and turnover intention in health care. Turnover in health care is a serious concern, as it contributes to the global nursing shortage and is associated with declines in quality of care, patient safety and patient outcomes. Turnover also impacts care teams and is associated with decreased staff cohesion and morale. A survey was developed and administered to frontline nurses working in the Province of Ontario, Canada. The data were used to test a hypothetical model developed from a review of the literature. The relationships amongst the three constructs were evaluated using structural equation modelling and mediation analysis. The hypothesised model was generally supported, although we were limited to considerations of interpersonal justice, affective commitment to one's organisation and turnover intention. Interpersonal justice is associated with affective commitment to one's organisation, which is negatively associated with turnover intention. Interpersonal justice was also found to be directly and negatively associated with turnover intention. Affective commitment to one's organisation was also found to mediate the relationship between interpersonal justice and turnover intention. The examination of relationships within the "employee retention triad" in a single, comprehensive model is novel and provides new information regarding relational complexity and insights into what healthcare leaders can do to retain employees. Reducing turnover may help to decrease some of the stressors related to turnover for clinical staff remaining at the organisation such as constant onboarding and orientation of new hires, working with less experienced staff and increased workload due to decreased staffing. © 2018 John Wiley & Sons Ltd.

    The objective of our study was to develop an automated calculation method to provide organ dose assessment for a large cohort of pediatric and adult patients undergoing CT examinations. We adopted two dose libraries that were previously published: the volume CT dose index-normalized organ dose library and the tube current-exposure time product (100 mAs)-normalized weighted CT dose index library. We developed an algorithm to calculate organ doses using the two dose libraries and the CT parameters available from DICOM data. We calculated organ doses for pediatric (n = 2499) and adult (n = 2043) CT examinations randomly selected from four health care systems in the United States and compared the adult organ doses with the values calculated from the ImPACT calculator. The median brain dose was 20 mGy (pediatric) and 24 mGy (adult), and the brain dose was greater than 40 mGy for 11% (pediatric) and 18% (adult) of the head CT studies. Both the National Cancer Institute (NCI) and ImPACT methods provided similar organ doses (median discrepancy < 20%) for all organs except the organs located close to the scanning boundaries. The visual comparisons of scanning coverage and phantom anatomies revealed that the NCI method, which is based on realistic computational phantoms, provides more accurate organ doses than the ImPACT method. The automated organ dose calculation method developed in this study reduces the time needed to calculate doses for a large number of patients. We have successfully used this method for a variety of CT-related studies including retrospective epidemiologic studies and CT dose trend analysis studies.

    The symptoms of posttraumatic stress disorder (PTSD) and chronic pain are thought to interact to increase the severity and impact of both conditions, but the mechanisms by which they interact remain unclear. This study examines the relationship between PTSD and chronic pain and whether indices of Psychological Flexibility mediate the relationship between these 2 conditions. Standardized self-report measures of PTSD, pain severity, pain interference, depression, and psychological flexibility (pain-related acceptance, committed action, cognitive fusion, and values-based action) were obtained from 315 people seeking treatment for chronic pain who also reported at least 1 traumatic experience. People seeking treatment for chronic pain and reporting symptoms consistent with a current diagnosis of PTSD had significantly higher levels of pain severity, pain interference, depression, and cognitive fusion and lower levels of pain-related acceptance and committed action than those reporting symptoms below the diagnostic threshold for PTSD. Pain-related acceptance, committed action, cognitive fusion, and depression mediated the relationship between PTSD and pain severity/interference, with pain-related acceptance being the strongest mediator from the Psychological Flexibility model. Processes from the Psychological Flexibility model were identified as mediators of the relationship between PTSD and chronic pain in people seeking treatment for chronic pain. The Psychological Flexibility model may be useful as an overarching model to help understand the relationship between PTSD and chronic pain. It is possible that targeting pain-related acceptance, committed action, and cognitive fusion (among other processes) in the treatment of chronic pain may produce corresponding improvements in comorbid symptoms of PTSD when these are present and may reduce impacts of PTSD on outcomes of chronic pain. Conversely, targeting of these processes in the treatment of PTSD may produce similar improvements for symptoms of chronic pain. Further research to evaluate these possibilities is needed.

    Investigations of workplace bullying in health care settings have tended to focus on nurses or other clinical staff. However, the organizational and power structures enabling bullying in health care are present for all employees, including administrative staff. : The purpose of this study was to specifically focus on health care administration staff and examine the prevalence and consequences of workplace bullying in this occupational group. A cross-sectional study was conducted based on questionnaire data from health care administration staff who work across facilities within a medium to large health care organization in Australia. The questionnaire included measures of bullying, negative affectivity (NA), job satisfaction, organizational commitment, well-being, and psychological distress. The three hypotheses of the study were that (a) workplace bullying will be linked to negative employee outcomes, (b) individual differences on demographic factors will have an impact on these outcomes, and (c) individual differences in NA will be a significant covariate in the analyses. The hypotheses were tested using t tests and analyses of covariances. A total of 150 health care administration staff completed the questionnaire (76% response rate). Significant main effects were found for workplace bullying, with lower organizational commitment and well-being with the effect on commitment remaining over and above NA. Main effects were found for age on job satisfaction and for employment type on psychological distress. A significant interaction between bullying and employment type for psychological distress was also observed. Negative affectivity was a significant covariate for all analyses of covariance. The applications of these results include the need to consider the occupations receiving attention in health care to include administration employees, that bullying is present across health care occupations, and that some employees, particularly part-time staff, may need to be managed slightly differently to the full-time workforce.

    The implantation energy and retained dose uniformity in enhanced glow discharge plasma immersion ion implantation (EGD-PIII) is investigated numerically and experimentally. Depth profiles obtained from different samples processed by EGD-PIII and traditional PIII are compared. The retained doses under different pulse widths are calculated by integrating the area under the depth profiles. Our results indicate that the improvement in the impact energy and retained dose uniformity by this technique is remarkable.

    To verify with empirical evidence the hypothesised relation and the effect of quality of work life, job embeddedness and affective commitment on turnover intention of clinical nurses in China. High turnover of the nursing workforce in healthcare organisations is a difficult and recurring problem in China as well as in many other countries in the world. It leads to great waste of resources and increases management cost. Developing and retaining the nursing workforce, which is a major challenge faced by human resources practitioners in hospitals and public health agencies, also becomes a subject of interest for management studies. Most of the literature about voluntary turnover focused on such traditional measures as job satisfaction and job alternatives in the past. The introduction of such new concepts as quality of work life, job embeddedness and affective commitment, which views the issue from a much broader and comprehensive spectrum, made a great breakthrough in the turnover study. In this study, we selected quality of work life, job embeddedness and affective commitment - three of the most important factors in employer-employee relations - and analysed the interaction between each one of them, as well as their co-effect on turnover intention of Chinese nurses. Cross-sectional survey and structural equation modelling were applied in studying the self-report questionnaires distributed to 1000 nurses employed in five large-scale government-owned hospitals in Heilongjiang Province, Northeast China. Our study confirmed the hypothesised positive relation of quality of work life with job embeddedness and affective commitment and the hypothesised negative relation of quality of work life with turnover intention, that is, high quality of work life perceived by the nurses enhances their job embeddedness and affective commitment and thus reduces their intention to leave the job. The effect of quality of work life is positive on job embeddedness and affection commitment and negative on turnover intention. Nurse managers should pay great attention to the nurses' perception of quality of work life, and make great efforts in developing strategies and projects that can strengthen the nurses' embeddedness or connection with the job. © 2012 Blackwell Publishing Ltd.

    Malaysia, a rapidly growing industrial country, is susceptible to pollution via large-scale industrial engagements and associated human activities. One particular concern is the potential impact upon the quality of locally resourced vegetables, foodstuffs that contain important nutrients necessary for good health, forming an essential part of the Malaysian diet. As a part of this, it is of importance for there to be accurate knowledge of radioactive material uptake in these vegetables, not least in respect of any public health detriment. Herein, using HPGe γ-ray spectrometry, quantification has been performed of naturally occurring radionuclides in common edible vegetables and their associated soils. From samples analyses, the soil activity concentration ranges (in units of Bq/kg) for (226)Ra, (232)Th and (40)K were respectively 1.33-30.90, 0.48-26.80, 7.99-136.5 while in vegetable samples the ranges were 0.64-3.80, 0.21-6.91, 85.53-463.8. Using the corresponding activities, the transfer factors (TFs) from soil-to-vegetables were estimated, the transfers being greatest for (40)K, an expected outcome given the essentiality of this element in support of vigorous growth. The TFs of (226)Ra and (232)Th were found to be in accord with available literature data, the values indicating the mobility of these radionuclides to be low in the studied soils. Committed effective dose and the associated life-time cancer risk was estimated, being found to be below the permissible limit proposed by UNSCEAR. Results for the studied media show that the prevalent activities and mobilities pose no significant threat to human health, the edible vegetables being safe for consumption.

    Currently, the United States Nuclear Regulatory Commission (NRC) has standards for procedures, performance activities and technical specifications on storage of Low-Level Radioactive Waste (LLRW) under 10 CFR Part 20. The United States Environmental Protection Agency (EPA) is proposing environmental standards for the management, storage and disposal of LLRW. The proposed standards, which will become 40 CFR part 193 when finalized, limits the committed effective dose to members of the public from the management and storage of LLRW, committed effective doses resulting from LLRW disposal and levels of radiological contamination of underground sources of drinking water as a result of themore » activities subject to management, storage and disposal of LLRW. Further, under Title III of the Clean Air Act Amendments, radionuclides are required to be inventoried for all generators. For hospitals and medical research institutions, quantities of LLRW are often below the concentrations required under reporting and record keeping requirements of 10 CFR 20. However, in many instances, the facility may require NRC permits and compliance with air quality dispersion modeling requirements. This paper presents the typical radionuclides used in hospitals and medical research institutions, and strategies to evaluate their usage and steps to achieve compliance. Air quality dispersion modeling by use of the COMPLY model is demonstrated to evaluate the fate of radionuclides released from on-site incineration of LLRW. The paper concludes that no significant threat is posed from the incineration of LLRW.« less

    To identify effects of the huddling programme as a strategy for retention of clinical nurses. In Korea, new nurses leave hospitals more than experienced nurses for many reasons. Hospitals with a high nurse turnover require larger budgets and longer periods of time to train large numbers of newly recruited nurses until they can perform as well as those who have left. Furthermore, the remaining nurses have an additional workload associated with both the shortage of manpower and the need to train the incoming nurses. This means that reducing nurse turnover intention requires preventive measures that promote empowerment and organisational commitment among nurses in Korea. Randomised controlled trial. This research used a pretest-post-test experimental-group-control-group design to investigate the effect of the huddling programme. The participants were 49 clinical nurses working at two general hospitals with more than 500 beds that are located in D city and S city of Korea. The experimental group participated in the huddling programme that comprised a full-day retreat and after-work social networking services during January and February 2013. Self-reported questionnaires were used to assess empowerment, organisational commitment and ego-resilience. The data were analysed by descriptive analysis using the t-test. The mean scores for normative commitment and impact of empowerment were higher in the experimental group, but ego-resilience did not differ significantly between the two groups. The huddling program positively increased nurses' perception of organisational commitment and empowerment who participated in huddling programme. The huddling programme could be a useful strategy for improving the retention of clinical nurses. This study is both significant and relevant to nursing science and practice given that it demonstrated the effectiveness of an empowerment programme in increasing organisational commitment and decreasing actual turnover rates of clinical nurses. © 2016 John Wiley & Sons Ltd.

  13. The ethical commitments of academic faculty in psychiatric education.

    2006-01-01

    This article explores the commitment of faculty to ethics training in psychiatric education. Although psychiatry has insufficiently addressed the profession's need for ethics training in education, program directors acknowledge its critical importance, and its positive impact has been demonstrated. Additionally, residents often seek ethics training as part of their instruction. The author suggests that academic faculty could respond to the profession's inadequate treatment of ethics training by helping trainees develop moral agency--the ability to recognize, assess, and respond to ethical dilemmas; decide what constitutes right or wrong care; and act accordingly. The author also describes how this objective could be met by promoting professionalism and offering didactic instruction that address substantive and process issues regarding psychiatric care. Specific recommendations are provided.

  15. Physician-Assisted Suicide and Other Forms of Euthanasia in Islamic Spiritual Care.

    PubMed

    Isgandarova, Nazila

    2015-12-01

    The muteness in the Qur'an about suicide due to intolerable pain and a firm opposition to suicide in the hadith literature formed a strong opinion among Muslims that neither repentance nor the suffering of the person can remove the sin of suicide or mercy 'killing' (al-qatl al-rahim), even if these acts are committed with the purpose of relieving suffering and pain. Some interpretations of the Islamic sources even give advantage to murderers as opposed to people who commit suicide because the murderers, at least, may have opportunity to repent for their sin. However, people who commit suicide are 'labeled' for losing faith in the afterlife without a chance to repent for their act. This paper claims that Islamic spiritual care can help people make decisions that may impact patients, family members, health care givers and the whole community by responding to questions such as 'What is the Islamic view on death?', 'What is the Islamic response to physician-assisted suicide and other forms of euthanasia?', 'What are the religious and moral underpinnings of these responses in Islam?' © The Author(s) 2015.

    This article looks into how perceptions of experience-based analysis (EBA) influence causal explanations of accidents given by managers and workers in the chemical industry (n=409) and in the nuclear industry (n=222). The approach is based on the model of naive explanations of accidents (Kouabenan, 1999, 2006, 2009), which recommends taking into account explanations of accidents spontaneously given by individuals, including laypersons, not only to better understand why accidents occur but also to design and implement the most appropriate prevention measures. The study reported here describes the impact of perceptions about EBA (perceived effectiveness, personal commitment, and the feeling of being involved in EBA practices) on managers' and workers' explanations of accidents likely to occur at the workplace. The results indicated that both managers and workers made more internal explanations than external ones when they perceived EBA positively. Moreover, the more the participants felt involved in EBA, were committed to it, and judged it effective, the more they explained accidents in terms of factors internal to the workers. Recommendations are proposed for reducing defensive reactions, increasing personal commitment to EBA, and improving EBA effectiveness. © 2013.

    Objective To explore staff perceptions about sustainability, commitment to change, participation in change process, and information received about the change project within the Veterans Administration Primary Care and Mental Health Integration (PC-MHI) initiative and to examine differences from the Veterans Health Administration Mental Health Systems Redesign (MHSR) initiative. Data Sources Surveys of change team members involved in the Veterans Affairs PC-MHI and MHSR initiatives. Study Design One-way analysis of variance examined the relationship between commitment, participation and information, and sustainability. Differences in PC-MHI sustainability were explored by location and job classification. Staff sustainability perceptions were compared with MHSR results. Principal Findings Sustainability differed by staff discipline. Difference between MHSR and PC-MHI existed by job function and perceptions about the change benefits. Participation in the change process and information received about the change process were positively correlated with sustainability. Staff commitment to change was positively associated with staff perceptions about the benefits of change and staff attitudes toward change. Conclusions Sustainability is an important part of organizational change efforts. Change complexity seems to influence perception about sustainability and impacts staff perceptions about the benefits of change. These perceptions seem to be driven by the information received and opportunities to participate in the change process. Further research is needed to understand how information and participation influence sustainability and affect employee commitment to change. PMID:23011071

    Global commitments to nutrition have supported calls for better evidence to support effective investments at national level. However, too little attention has so far been paid to the role of governance in achieving impacts. This article explores the ways by which the commitment and capabilities of policy implementers affect collaborative efforts for achieving nutrition goals. Over 1370 structured interviews were held with government and nongovernment officials over 3 years in 21 districts. Coded responses supported quantitative analysis of stakeholders' knowledge, attitudes, and practices regarding policy implementation. Stakeholder commitment was already high in 2013 when a new national policy was adopted, but capabilities were weak. Only one-third of interviewed respondents had any nutrition training. Rollout of training focusing on districts targeted for early implementation of multisector programming. This raised levels of nutrition training among interviewed respondents to 57% in 2015, which raised demand for technical information to support actions. Better understanding of the complexity of cross-sector work led to calls for higher budgets and more effective cross-sectoral collaboration. Nepal offers an example of effective efforts to improve nutrition governance across sectors at all levels of administration. The promotion of awareness, capacity, and new ways of working shows promise. Trainings, information sharing, and management support led to growing willingness among civil servants to engage across sectors. Structured surveys offer a viable way to track change across institutions and sectors. © The Author(s) 2016.

    To automate astronaut organ and effective dose calculations from occupational X-ray and computed tomography (CT) examinations incorporating PCXMC and ImPACT tools and to estimate the associated lifetime cancer risk per the National Council on Radiation Protection & Measurements (NCRP) using MATLAB(R). Methods: NASA follows guidance from the NCRP on its operational radiation safety program for astronauts. NCRP Report 142 recommends that astronauts be informed of the cancer risks from reported exposures to ionizing radiation from medical imaging. MATLAB(R) code was written to retrieve exam parameters for medical imaging procedures from a NASA database, calculate associated dose and risk, and return results to the database, using the Microsoft .NET Framework. This code interfaces with the PCXMC executable and emulates the ImPACT Excel spreadsheet to calculate organ doses from X-rays and CTs, respectively, eliminating the need to utilize the PCXMC graphical user interface (except for a few special cases) and the ImPACT spreadsheet. Results: Using MATLAB(R) code to interface with PCXMC and replicate ImPACT dose calculation allowed for rapid evaluation of multiple medical imaging exams. The user inputs the exam parameter data into the database and runs the code. Based on the imaging modality and input parameters, the organ doses are calculated. Output files are created for record, and organ doses, effective dose, and cancer risks associated with each exam are written to the database. Annual and post-flight exposure reports, which are used by the flight surgeon to brief the astronaut, are generated from the database. Conclusions: Automating PCXMC and ImPACT for evaluation of NASA astronaut medical imaging radiation procedures allowed for a traceable and rapid method for tracking projected cancer risks associated with over 12,000 exposures. This code will be used to evaluate future medical radiation exposures, and can easily be modified to accommodate changes to the risk calculation procedure.

    Objectives: To assess the proportion of critical errors committed while demonstrating the inhaler technique in hospitalized patients diagnosed with asthma and chronic obstructive pulmonary disease (COPD). Methods: This cross-sectional observational study was conducted in 47 asthmatic and COPD patients using inhaler devices. The study took place at King Abdulaziz Medical City, Riyadh, Saudi Arabia between September and December 2013. Two pharmacists independently assessed inhaler technique with a validated checklist. Results: Seventy percent of patients made at least one critical error while demonstrating their inhaler technique, and the mean number of critical errors per patient was 1.6. Most patients used metered dose inhaler (MDI), and 73% of MDI users and 92% of dry powder inhaler users committed at least one critical error. Conclusion: Inhaler technique in hospitalized Saudi patients was inadequate. Health care professionals should understand the importance of reassessing and educating patients on a regular basis for inhaler technique, recommend the use of a spacer when needed, and regularly assess and update their own inhaler technique skills.
