Population dose commitments due to radioactive releases from nuclear power plant sites in 1983

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

Baker, D.A.; Peloquin, R.A.

Population radiation dose commitments have been estimated from reported radionuclide releases from commercial power reactors operating during 1983. Fifty-year dose commitments from a one-year exposure were calculated from both liquid and atmospheric releases for four population groups (infant, child, teen-ager and adult) residing between 2 and 80 km from each of 52 sites. This report tabulates the results of these calculations, showing the dose commitments for both liquid and airborne pathways for each age group and organ. Also included for each of the sites is a histogram showing the fraction of the total population within 2 to 80 km aroundmore » each site receiving various average dose commitments from the airborne pathways. The total dose commitments (from both liquid and airborne pathways) for each site ranged from a high of 45 person-rem to a low of 0.002 person-rem for the sites with plants operating throughout the year with an arithmetic mean of 3 person-rem. The total population dose for all sites was estimated at 170 person-rem for the 100 million people considered at risk.« less

In Morocco, thermal waters have been used for decades for the treatment of various diseases. 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.

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.

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

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.

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

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

Hoenes, G.R.; Soldat, J.K.

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

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.

Objective The present study explored treatment dose and patient engagement as predictors of treatment outcome in cognitive behavioral therapy (CBT) for anxiety disorders. Method 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 that selected CBT as treatment modality. Results Completing exposures, high attendance, and being more homework adherent predicted better outcomes across all measures at 12 and 18 months, and high CBT commitment predicted better outcomes on all measures at 18 months. Conclusions 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.

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.

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.

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

PubMed

Crick, M J; Linsley, G S

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.

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.

Protracted exposure to fallout: the Rongelap and Utirik experience.

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.

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.

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.

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.

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.

We evaluated the current concentrations of radiocesium in local foods collected in Kawauchi Village, which is located less than 30 km from Fukushima Daiichi Nuclear Power Station, to minimize public anxiety regarding internal radiation exposure through the consumption of locally produced foods after the 2011 Fukushima accident. The number of samples exceeding the regulatory radiocesium limit (100 Bq/kg for general foods) was five out of 4,080 vegetables (0.1%), 652 of 1,986 (32.8%) among edible wild plants and fungi, and eight of 647 (1.2%) in fruits. Our study confirmed that the internal radiation doses of ingesting these foods are acceptably low compared to the public dose limit, ranging from 24.4 to 42.7 μSv for males and from 21.7 to 43.4 μSv for females, although the potential for radiation exposure still exists. Long-term comprehensive follow-up should take place to clarify trends in radiocesium concentrations in local foods and the committed effective doses found in Fukushima-area residents. By constructing a system that allows residents to access information on radiocesium concentration in foods, a risk communication model between specialists and residents could be developed in the recovery phase after the Fukushima accident.

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.

210Po in the diet at Seville (Spain) and its contribution to the dose by ingestion

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.

The 2007 Recommendations of the International Commission on Radiological Protection (ICRP, 2007) introduced changes that affect the calculation of effective dose, and implied a revision of the dose coefficients for internal exposure, published previously in the Publication 30 series (ICRP, 1979, 1980, 1981, 1988) and Publication 68 (ICRP, 1994). In addition, new data are now available that support an update of the radionuclide-specific information given in Publications 54 and 78 (ICRP, 1988a, 1997b) for the design of monitoring programmes and retrospective assessment of occupational internal doses. Provision of new biokinetic models, dose coefficients, monitoring methods, and bioassay data was performed by Committee 2, Task Group 21 on Internal Dosimetry, and Task Group 4 on Dose Calculations. A new series, the Occupational Intakes of Radionuclides (OIR) series, will replace the Publication 30 series and Publications 54, 68, and 78. OIR Part 1 has been issued (ICRP, 2015), and describes the assessment of internal occupational exposure to radionuclides, biokinetic and dosimetric models, methods of individual and workplace monitoring, and general aspects of retrospective dose assessment. OIR Part 2 (ICRP, 2016), this current publication and upcoming publications in the OIR series (Parts 4 and 5) provide data on individual elements and their radioisotopes, including information on chemical forms encountered in the workplace; a list of principal radioisotopes and their physical half-lives and decay modes; the parameter values of the reference biokinetic model; and data on monitoring techniques for the radioisotopes encountered most commonly in workplaces. Reviews of data on inhalation, ingestion, and systemic biokinetics are also provided for most of the elements. Dosimetric data provided in the printed publications of the OIR series include tables of committed effective dose per intake (Sv Bq−1 intake) for inhalation and ingestion, tables of committed effective dose per content (Sv Bq−1 measurement) for inhalation, and graphs of retention and excretion data per Bq intake for inhalation. These data are provided for all absorption types and for the most common isotope(s) of each element. The electronic annex that accompanies the OIR series of publications contains a comprehensive set of committed effective and equivalent dose coefficients, committed effective dose per content functions, and reference bioassay functions. Data are provided for inhalation, ingestion, and direct input to blood. This third publication in the series provides the above data for the following elements: ruthenium (Ru), antimony (Sb), tellurium (Te), iodine (I), caesium (Cs), barium (Ba), iridium (Ir), lead (Pb), bismuth (Bi), polonium (Po), radon (Rn), radium (Ra), thorium (Th), and uranium (U).

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.

Relational job characteristics and nurses' affective organizational commitment: the mediating role of work engagement.

PubMed

Santos, Alda; Chambel, Maria José; Castanheira, Filipa

2016-02-01

To study work engagement as a mediator of the associations between relational job characteristics and nurses' affective commitment to the hospital. Earlier research has shown that work engagement mediates the relationship between job resources and affective organizational commitment. However, relational job characteristics, which may be job resources, have not been studied or examined in relation to work engagement and affective organizational commitment in the nursing profession. This study uses a correlational survey design and an online survey for data collection. Data for this correlational study were collected by survey over months (2013) from a sample of 335 hospital nurses. Measures included Portuguese translations of the Relational Job Characteristics' Psychological Effects Scale, the Utrecht Work Engagement Scale and the Affective Organizational Commitment Scale. Data analysis supports a full mediation model where relational job characteristics explained affective commitment to the hospital through nurses' work engagement. Relational job characteristics contribute to nurses' work engagement, which in turn contributes to affective organizational commitment. © 2015 John Wiley & Sons Ltd.

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.

To predict nurses' job involvement on the basis of their organizational commitment and personal characteristics at a large tertiary hospital in Saudi Arabia. Data were collected in 2015 from a convenience sample of 558 nurses working at a large tertiary hospital in Riyadh, Saudi Arabia. A cross-sectional correlational design was used in this study. Data were collected using a structured questionnaire. All commitment scales had significant relationships. Multiple linear regression analysis revealed that the model predicted a sizeable proportion of variance in nurses' job involvement (p < 0.001). High organizational commitment enhances job involvement, which may lead to more organizational stability and effectiveness.

Not All Differentiation is the Same: Examining the Moderating Effects of Leader-Member Exchange (LMX) Configurations.

Leaders often influence whether an employee stays or quits and yet research in collective turnover, or turnover at the work-unit level, has neglected leadership as a key antecedent. In the current study we examine how the quality of leader-member relationships within a group (i.e., leader-member exchange, LMX) influences building a shared mindset of collective organizational commitment and ultimately influences collective turnover. We build on a key tenet of LMX theory that leaders form differentiated relationships with followers and propose that not all LMX differentiation is the same and therefore, researchers must take into account the configuration, or mix of high and low LMX relationships, within a group. We expect LMX configurations will moderate the influence of LMX differentiation on collective turnover through the mechanism of collective organizational commitment. We find 5 configurations of LMX relationships, including a bimodal, solo-status low LMX, solo-status high LMX, and 2 fragmented configurations. As hypothesized, LMX differentiation positively relates to collective organizational commitment and negatively relates to collective turnover in a solo-status low LMX configuration and a fragmented LMX configuration, and negatively relates to collective organizational commitment and positively relates to collective turnover in a bimodal configuration. Theoretical implications and future research directions are discussed. (PsycINFO Database Record (c) 2017 APA, all rights reserved).

2016-02-01

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.

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.

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

Commitment to nursing: results of a qualitative interview study.

PubMed

Gould, Dinah; Fontenla, Marina

2006-04-01

The aims of the study were to explore opportunities to undergo continuing professional education, family friendly policy and holding an innovative or traditional post on nurses' job satisfaction and professional and organizational commitment. Qualified nurses have become a scare resource in the National Health Service. Managers need to be aware of the work-related factors most likely to secure nurses' professional and organizational commitment which will contribute to the retention. Commitment is thought to be increased if opportunities for continuing professional education are good. Family friendly policy is also important. Less is known about the relationship between type of nursing work and commitment. An in-depth, exploratory approach to data collection were taken, employing an interview guide with open-ended questions. Data were collected with 27 nurses in clinical grades in two contrasting trusts. Family friendly policies emerged as most important in securing nursing commitment. Those in innovative posts whose work entailed social hours and greater professional autonomy also displayed greater levels of job satisfaction. Opportunities for continuing professional education had less influence on professional and organizational commitment. Providing flexible or social working hours appears to be more influential than providing opportunities for continuing professional education in securing nursing commitment in this exploratory study.

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

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

PubMed

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.

Athletic Trainers' Facilitators of Professional Commitment in the Collegiate Setting

PubMed Central

Eason, Christianne M.; Mazerolle, Stephanie M.; Pitney, William A.

2015-01-01

Context: Professional responsibility, rewards and respect, and time for rejuvenation are factors supporting professional commitment for athletic trainers (ATs) in the high school setting. The inherent complexities of an occupational setting can mitigate perceptions of professional commitment. Thus far, evidence is lacking regarding professional commitment for ATs in other occupational settings. Objective: To extend the literature on professional commitment of the AT to the collegiate setting. Design: Qualitative study. Setting: Collegiate. Patients or Other Participants: Thirty-three Board of Certification-certified ATs employed in the collegiate setting (National Collegiate Athletic Association Division I = 11, Division II = 9, Division III = 13) with an average of 10 ± 8 years of clinical experience volunteered. Data saturation guided the total number of participants. Data Collection and Analysis: Online journaling via QuestionPro was used to collect data from all participants. Two strategies, multiple-analyst triangulation and peer review, were completed to satisfy data credibility. Data were evaluated using a general inductive approach. Results: Likert-scale data revealed no differences regarding levels of professional commitment across divisions. Two themes emerged from the inductive-content analysis: (1) professional responsibility and (2) coworker support. The emergent theme of professional responsibility contained 4 subthemes: (1) dedication to advancing the athletic training profession, (2) ardor for job responsibilities, (3) dedication to the student-athlete, and (4) commitment to education. Our participants were able to better maintain their own professional commitment when they felt their coworkers were also committed to the profession. Conclusions: The collegiate ATs investigated in this study, regardless of division, demonstrated professional commitment propelled by their aspiration to advance the profession, as well as their dedication to student-athletes and athletic training students. Maintaining commitment was influenced by a strong sense of coworker support. PMID:25761135

The U.S. Department of Energy (DOE) Office of Analysis within the Office of Health, Safety and Security (HSS) publishes the annual DOE Occupational Radiation Exposure Report to provide an overview of the status of radiation protection practices at DOE (including the National Nuclear Security Administration [NNSA]). The DOE 2012 Occupational Radiation Exposure Report provides an evaluation of DOE-wide performance regarding compliance with Title 10, Code of Federal Regulations (C.F.R.), Part 835, Occupational Radiation Protection dose limits and as low as reasonably achievable (ALARA) process requirements. In addition, the report provides data to DOE organizations responsible for developing policies for protectionmore » of individuals from the adverse health effects of radiation. The report provides a summary and an analysis of occupational radiation exposure information from the monitoring of individuals involved in DOE activities. Over the past 5-year period, the occupational radiation exposure information is analyzed in terms of aggregate data, dose to individuals, and dose by site. As an indicator of the overall amount of radiation dose received during the conduct of operations at DOE, the report includes information on collective total effective dose (TED). The TED is comprised of the effective dose (ED) from external sources, which includes neutron and photon radiation, and the internal committed effective dose (CED), which results from the intake of radioactive material into the body. The collective ED from photon exposure decreased by 23% between 2011 and 2012, while the neutron dose increased by 5%. The internal dose components of the collective TED decreased by 7%. Over the past 5-year period, 99.99% of the individuals receiving measurable TED have received doses below the 2 roentgen equivalent in man (rems) (20 millisievert [mSv]) TED administrative control level (ACL), which is well below the DOE regulatory limit of 5 rems (50 mSv) TED annually. The occupational radiation exposure records show that in 2012, DOE facilities continued to comply with DOE dose limits and ACLs and worked to minimize exposure to individuals. The DOE collective TED decreased 17.1% from 2011 to 2012. The collective TED decreased at three of the five sites with the largest collective TED. u Idaho Site – Collective dose reductions were achieved as a result of continuing improvements at the Advanced Mixed Waste Treatment Project (AMWTP) through the planning of drum movements that reduced the number of times a container is handled; placement of waste containers that created highradiation areas in a centralized location; and increased worker awareness of high-dose rate areas. In addition, Idaho had the largest decrease in the total number of workers with measurable TED (1,143 fewer workers). u Hanford Site (Hanford) – An overall reduction of decontamination and decommissioning (D&D) activities at the Plutonium Finishing Plant (PFP) and Transuranic (TRU) retrieval activities resulted in collective dose reductions. u Savannah River Site (SRS) – Reductions were achieved through ALARA initiatives employed site wide. The Solid Waste Management Facility used extended specialty tools, cameras and lead shield walls to facilitate removal of drums. These tools and techniques reduce exposure time through improved efficiency, increase distance from the source of radiation by remote monitoring, shield the workers to lower the dose rate, and reduce the potential for contamination and release of material through repacking of waste. Overall, from 2011 to 2012, there was a 19% decrease in the number of workers with measurable dose. Furthermore, due to a slight decrease in both the DOE workforce (7%) and monitored workers (10%), the ratio of workers with measurable doses to monitored workers decreased to 13%. Another primary indicator of the level of radiation exposure covered in this report is the average measurable dose, which normalizes the collective dose over the population of workers who actually received a measurable dose. The average measurable TED increased by 3% from 2011 to 2012. Additional analyses show that the dose distribution in 2012 was similar to the distribution in 2011. In 2012, 13% of the monitored workers received a measurable TED and the average measurable TED, 0.069 rem, was less than 2% of the DOE limit. From 2011 to 2012, the collective TED and the number of individuals with measurable TED decreased 17.1% and 19%, respectively. These decreases were mainly due to an overall reduction of D&D activities at the PFP and TRU retrieval activities at Hanford; a 78% decrease in the number of targeted waste drums that were processed at the Idaho Site’s Accelerated Retrieval Project (ARP) from 5,566 drums in 2011 to a total of 1,211 drums processed in 2012; and ALARA initiatives employed site wide at SRS. In addition, the decreases were the result of decreased American Recovery and Reinvestment Act (ARRA) activities and continuing D&D, particularly at the DOE sites that comprise the majority of DOE collective dose. Over the past 5 years, the size of the monitored workforce has remained at a fairly stable level (within 12%), while the collective dose has varied up to 37%. No reported doses exceeded the DOE occupational limit of 5 rems TED in 2012 and no reported doses exceeded the DOE ACL of 2 rems TED.« less

Test a model of family physician job satisfaction and commitment. Data were collected from 1,482 family physicians in a Midwest state during 2000-2001. The sampling frame came from the membership listing of the state's family physician association, and the analyzed dataset included family physicians employed by large multispecialty group practices. A cross-sectional survey was used to collect data about physician working conditions, job satisfaction, commitment, and demographic variables. The response rate was 47 percent. Different variables predicted the different measures of satisfaction and commitment. Satisfaction with one's health care organization (HCO) was most strongly predicted by the degree to which physicians perceived that management valued and recognized them and by the extent to which physicians perceived the organization's goals to be compatible with their own. Satisfaction with one's workgroup was most strongly predicted by the social relationship with members of the workgroup; satisfaction with one's practice was most strongly predicted by relationships with patients. Commitment to one's workgroup was predicted by relationships with one's workgroup. Commitment to one's HCO was predicted by relationships with management of the HCO. Social relationships are stronger predictors of employed family physician satisfaction and commitment than staff support, job control, income, or time pressure.

The purpose of this quality improvement project was to implement an evidence-based practice guideline for assessment and documentation of the civil commitment process. Participants included six civil commitment examiners who conduct court ordered psychiatric evaluations at two crisis intervention centers in rural area of southeaster state. Data collection was conducted utilizing a chart audit tool both pre and post intervention of 100 civil commitment evaluations. The intervention included the development of an evidenced based form for documentation of civil commitment evaluations and a one on one educational training session was conducted for each participant. Descriptive statistics (t test) was utilized to analyze the data collected. The project demonstrated a significant increase as 25.5 % of evaluations contained the America Psychiatric Association's recommended 11 domains of assessment prior to implementation compared to 65.6 % (p value = 0.018) post implementation. Moreover, participants with family practice training showed an increase in commitment rates from 60 to 77.3 % (p value = 0.066). Whereas, psychiatric trained participants showed a decrease from 83.75 to 77.66 % (p value = 0.38). Demonstrating that court ordered evaluations guided by a standardized form based on evidence affected examiners recommendations for commitments.

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.

210Po, 210Pb, 40K and 137Cs in edible wild berries and mushrooms and ingestion doses to man from high consumption rates of these wild foods.

This paper discusses activity concentrations of (210)Po, (210)Pb, (40)K and (137)Cs in edible wild berries and mushrooms collected from Øvre Dividalen national park, Northern Norway and derives committed effective ingestion doses to man based on high consumption rates of these wild foods. Edible wild berries and mushrooms accumulated similar levels of (210)Pb, but mushrooms accumulated higher levels of (210)Po and (40)K than berries. There appears to be a clear difference in the ability of Leccinum spp. of fungi to accumulate (210)Po and/or translocate (210)Po to mushrooms compared to Russula spp. of fungi. Activity concentrations of (137)Cs in edible wild berries and mushrooms from Øvre Dividalen national park reflected the lower levels of fallout of this radionuclide in Northern Norway compared to more central areas following the Chernobyl accident. For mushrooms, ingestion doses are dominated by (210)Po, while for berries, (40)K is typically the main contributor to dose. Based on high consumption rates, ingestion doses arising from the combination of (210)Po, (210)Pb and (40)K were up to 0.05 mSv/a for berries and 0.50 mSv/a for mushrooms. Consumption of such wild foods may result in a significant contribution to total annual doses when consumed in large quantities, particularly when selecting mushrooms species that accumulate high activity concentrations of (210)Po.

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.

Klumpp, John Allan; Bertelli, Luiz; Waters, Tom L.

For radionuclides such as plutonium and americium, detection of removable activity in the nose (i.e., nasal swab measurements) are frequently used to determine whether follow-up bioassay measurements are warranted following a potential intake. For this paper, the authors analyzed 429 nasal swab measurements taken following incidents or suspicious circumstances (such as an air monitor alarming) at Los Alamos National Laboratory (LANL) for which the dose was later evaluated using in vitro bioassay. Nasal swab measurements were found to be very poor predictors of dose and should not be used as such in the field. However, nasal swab measurements can bemore » indicative of whether a reliably detectable committed effective dose (CED) occurred. About 14% of nasal swab measurements between 1.25 and 16.7 Bq corresponded to CEDs greater than 1 mSv, so in general, positive nasal swabs always indicate that follow-up bioassay should be performed (positive nasal swabs less than 1.25 Bq are considered separately). This probability increased significantly for nasal swabs greater than 16.7 Bq. Only about 3% of nasal swabs with no detectable activity (NDA) corresponded to reliably detectable CEDs. As a result, a nasal swab with NDA is therefore necessary, but not sufficient, to negate the need for a follow-up bioassay if it was collected following other workplace indicators of a potential intake.« less

Relationships among perceived career support, affective commitment, and work engagement.

PubMed

Poon, June M L

2013-01-01

This study sought to test the predictive effects of perceived career support and affective commitment on work engagement. It was hypothesized that perceived career support would relate positively to work engagement and this relationship would be transmitted through affective commitment. Survey data were collected from 115 full-time employees enrolled as part-time graduate students in a large public university in Malaysia. Multiple regression analysis yielded results indicating that the relationship between perceived career support and work engagement was mediated by affective commitment. This finding suggests that employers can promote employee work engagement by ensuring employees perceive their organization to be supportive of their career and increasing employees' level of affective commitment.

An accurate method to measure alpha-emitting natural radionuclides in atmospheric filters: Application in two NORM industries

In this work, an accurate method for the measurement of natural alpha-emitting radionuclides from aerosols collected in air filters is presented and discussed in detail. The knowledge of the levels of several natural alpha-emitting radionuclides (238U, 234U, 232Th, 230Th, 228Th, 226Ra and 210Po) in atmospheric aerosols is essential not only for a better understanding of the several atmospheric processes and changes, but also for a proper evaluation of the potential doses, which can inadvertently be received by the population via inhalation. The proposed method takes into account the presence of intrinsic amounts of these radionuclides in the matrices of the quartz filters used, as well as the possible variation in the humidity of the filters throughout the collection process. In both cases, the corrections necessary in order to redress these levels have been evaluated and parameterized. Furthermore, a detailed study has been performed into the optimisation of the volume of air to be sampled in order to increase the accuracy in the determination of the radionuclides. The method as a whole has been applied for the determination of the activity concentrations of U- and Th-isotopes in aerosols collected at two NORM (Naturally Occurring Radioactive Material) industries located in the southwest of Spain. Based on the levels found, a conservative estimation has been performed to yield the additional committed effective doses to which the workers are potentially susceptible due to inhalation of anthropogenic material present in the environment of these two NORM industries.

To understand the perception of the quality of leadership relationships and the organizational commitment of nurses, and to analyze the influence of this relationship quality. Cross-sectional and correlational study, with a quantitative approach, using a non-probability convenience sampling with 408 nurses. The data were collected through questionnaires at Central Hospital in Lisbon, between January and March 2013. The statistical analysis of the data was carried out using IBM® SPSS® Statistics 19 software. Three hundred forty-two questionnaires were considered valid. The quality of the leadership relationship was satisfactory, and the nurses were poorly committed to the organization. The quality of the leadership relationship was statistically correlated with organizational commitment: there was found a moderate association to affective commitment (rs=0.42, p<0.05), a low association with the normative commitment (rs=0.37, p<0.05), and a very low association with the calculative commitment (rs=0.14, p<0.05). Leadership exerts influence on organizational commitment. An opportunity to improve the quality of the leadership relationship between nurses and their leaders was found, with the consequent possibility of developing organizational commitment.

We investigate how two different types of conflict (task conflict and relationship conflict) at two different levels (individual-level and team-level) influence individual team commitment. The analysis was conducted using data we collected from 193 employees in 31 branch offices of a Korean commercial bank. The relationships at multiple levels were tested using hierarchical linear modeling (HLM). The results showed that individual-level relationship conflict was negatively related to team commitment while individual-level task conflict was not. In addition, both team-level task and relationship conflict were negatively associated with team commitment. Finally, only team-level relationship conflict significantly moderated the relationship between individual-level relationship conflict and team commitment. We further derive theoretical implications of these findings.

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.

Individual characteristics are important factors influencing organizational commitment. Also, committed human resources can lead organizations to performance improvement as well as personal and organizational achievements. This research aimed to determine the association between organizational commitment and personality traits among faculty members of Ahvaz Jundishapur University of Medical Sciences. the research population of this cross-sectional study was the faculty members of Ahvaz Jundishapur University of Medical Sciences (Ahvaz, Iran). The sample size was determined to be 83. Data collection instruments were the Allen and Meyer questionnaire for organizational commitment and Neo for characteristics' features. The data were analyzed through Pearson's product-moment correlation and the independent samples t-test, ANOVA, and simple linear regression analysis (SLR) by SPSS. Continuance commitment showed a significant positive association with neuroticism, extroversion, agreeableness, and conscientiousness. Normative commitment showed a significant positive association with conscientiousness and a negative association with extroversion (p = 0.001). Openness had a positive association with affective commitment. Openness and agreeableness, among the five characteristics' features, had the most effect on organizational commitment, as indicated by simple linear regression analysis. Faculty members' characteristics showed a significant association with their organizational commitment. Determining appropriate characteristic criteria for faculty members may lead to employing committed personnel to accomplish the University's objectives and tasks.

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.

Development of probabilistic internal dosimetry computer code

NASA Astrophysics Data System (ADS)

Noh, Siwan; Kwon, Tae-Eun; Lee, Jai-Ki

2017-02-01

Internal radiation dose assessment involves biokinetic models, the corresponding parameters, measured data, and many assumptions. Every component considered in the internal dose assessment has its own uncertainty, which is propagated in the intake activity and internal dose estimates. For research or scientific purposes, and for retrospective dose reconstruction for accident scenarios occurring in workplaces having a large quantity of unsealed radionuclides, such as nuclear power plants, nuclear fuel cycle facilities, and facilities in which nuclear medicine is practiced, a quantitative uncertainty assessment of the internal dose is often required. However, no calculation tools or computer codes that incorporate all the relevant processes and their corresponding uncertainties, i.e., from the measured data to the committed dose, are available. Thus, the objective of the present study is to develop an integrated probabilistic internal-dose-assessment computer code. First, the uncertainty components in internal dosimetry are identified, and quantitative uncertainty data are collected. Then, an uncertainty database is established for each component. In order to propagate these uncertainties in an internal dose assessment, a probabilistic internal-dose-assessment system that employs the Bayesian and Monte Carlo methods. Based on the developed system, we developed a probabilistic internal-dose-assessment code by using MATLAB so as to estimate the dose distributions from the measured data with uncertainty. Using the developed code, we calculated the internal dose distribution and statistical values ( e.g. the 2.5th, 5th, median, 95th, and 97.5th percentiles) for three sample scenarios. On the basis of the distributions, we performed a sensitivity analysis to determine the influence of each component on the resulting dose in order to identify the major component of the uncertainty in a bioassay. The results of this study can be applied to various situations. In cases of severe internal exposure, the causation probability of a deterministic health effect can be derived from the dose distribution, and a high statistical value ( e.g., the 95th percentile of the distribution) can be used to determine the appropriate intervention. The distribution-based sensitivity analysis can also be used to quantify the contribution of each factor to the dose uncertainty, which is essential information for reducing and optimizing the uncertainty in the internal dose assessment. Therefore, the present study can contribute to retrospective dose assessment for accidental internal exposure scenarios, as well as to internal dose monitoring optimization and uncertainty reduction.

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.

To examine whether involvement in committed dating relationships is associated with university students' mental health (depressive symptoms and problem alcohol use, including binge drinking), and whether these associations differ by gender. A sample of 889 undergraduate students aged 18 to 25. Self-report measures of dating relationship status, depression, and problematic alcohol use were collected via an online survey from August to December 2010. Involvement in a committed relationship, compared with being single, was associated with fewer depressive symptoms for college women but not for men. Committed relationship involvement was also associated with less problematic alcohol use for both genders. Findings suggest that involvement in committed relationships may be protective to college student mental health, and highlight the potential of healthy relationship programming to benefit student well-being.

Predictors of organizational commitment among staff in assisted living.

This study examines the role of organizational culture, job satisfaction, and sociodemographic characteristics as predictors of organizational commitment among staff in assisted living. It is particularly important to examine organizational commitment, because of its close links to staff turnover. Data were collected from 317 staff members in 61 facilities, using self-administered questionnaires. The facilities were selected from licensed assisted living programs and were stratified into small, traditional, and new-model homes. Staff questionnaires were distributed by a researcher during 1-day visits to each facility. Organizational commitment was measured by the extent of staff identification, involvement, and loyalty to the organization. Organizational culture, job satisfaction, and education were strong predictors of commitment, together explaining 58% of the total variance in the dependent variable. Higher levels of organizational commitment were associated with more favorable staff perceptions of organizational culture and greater job satisfaction. In addition, more educated staff members tended to report higher levels of organizational commitment. Other than education, sociodemographic characteristics failed to account for a significant amount of variance in organizational commitment. Because job satisfaction and organizational culture were strong predictors of commitment, interventions aimed at increasing job satisfaction and creating an organizational culture that values and respects staff members could be most effective in producing higher levels of organizational commitment.

For radionuclides such as plutonium and americium, detection of removable activity in the nose (i.e., nasal swab measurements) are frequently used to determine whether follow-up bioassay measurements are warranted following a potential intake. For this paper, the authors analyzed 429 nasal swab measurements taken following incidents or suspicious circumstances (such as an air monitor alarming) at Los Alamos National Laboratory (LANL) for which the dose was later evaluated using in vitro bioassay. Nasal swab measurements were found to be very poor predictors of dose and should not be used as such in the field. However, nasal swab measurements can bemore » indicative of whether a reliably detectable committed effective dose (CED) occurred. About 14% of nasal swab measurements between 1.25 and 16.7 Bq corresponded to CEDs greater than 1 mSv, so in general, positive nasal swabs always indicate that follow-up bioassay should be performed (positive nasal swabs less than 1.25 Bq are considered separately). This probability increased significantly for nasal swabs greater than 16.7 Bq. Only about 3% of nasal swabs with no detectable activity (NDA) corresponded to reliably detectable CEDs. As a result, a nasal swab with NDA is therefore necessary, but not sufficient, to negate the need for a follow-up bioassay if it was collected following other workplace indicators of a potential intake.« less

Marcellini, Anne; Perera, Éric; Rodhain, Angélique; Férez, Sylvain

2016-06-08

From a sociological perspective, physical activity and diet are perceived as social and cultural practices, constructed and transmitted within human societies. The body is then thought of as a social construct, a sign and foundation of individual and collective identities. In this context, this article was designed to highlight some social processes underlying the obesity epidemic. Clarifying issues about a medical definition of obesity in an obesogenic society, and theoretical approaches to the meanings of the obesity epidemic are proposed. Individual stories of a gradual shift towards obesity are presented to illustrate the variety of trajectories that can lead to obesity in adulthood but also the variety of subjective experiences about the situation of obesity. In particular, the relationship to the body and experiences in terms of physical activity are investigated in order to understand how obesity is associated with non-commitment, low commitment or abandonment of physical activity. The issue of configurations in which commitment or re-commitments in regular exercise for sedentary populations can be possible are discussed. The discussion shows that although commitment to regular and sustainable physical activity requires a profound transformation of lifestyle for the persons concerned, the collective dimension of this change is rarely taken into account..

Commitment to abstracting standards has a very significant role in information retrieval. The present research aimed to evaluate the rate of Commitment to ISO 214 Standard among the Persian abstracts of approved research projects at School of Health Management and Medical Informatics, Isfahan University of Medical Sciences, Isfahan, Iran. This descriptive study used a researcher-made checklist to collect data, which was then analyzed through content analysis. The studied population consisted of 227 approved research projects in the School of Health Management and Medical Informatics, Isfahan University of Medical Sciences during 2001-2010. The validity of the checklist was measured by face and content validity. Data was collected through direct observations. Statistical analyzes including descriptive (frequency distribution and percent) and inferential statistics (Chi-square test) were performed in SPSS-16. The highest and lowest commitment rates to ISO 214 standard were in using third person pronouns (100%) and using active verbs (34/4%), respectively. In addition, the highest commitment rates to ISO 214 standard (100%) related to mentioning third person pronouns, starting the abstract with a sentence to explain the subject of the research, abstract placement, and including keyword in 2009. On the other hand, during 2001-2003, the lowest commitment rate was observed in reporting research findings (16/7%). Moreover, various educational groups differed significantly only in commitment to study goals, providing research findings, and abstaining from using abbreviations, signs, and acronyms. Furthermore, educational level of the corresponding author was significantly related with extracting the keywords from the text. Other factors of ISO 214 standard did not have significant relations with the educational level of the corresponding author. In general, a desirable rate of commitment to ISO 214 standard was observed among the Persian abstracts of approved research projects at the School of Health Management and Medical Informatics of Isfahan University of Medical Sciences. However, commitment rates differed between years. In addition, commitment to ISO 214 standard was not significantly related with educational group and level.

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.

In this study, size fractionated mass and 210 Po activity concentrations in mainstream cigarette smoke (MCS) were monitored for three popular cigarette brands. Size segregated collection of MCS was carried out using a cascade type impactor, while mass and 210 Po activity concentration were analyzed gravimetrically and alpha spectrometry (following the radiochemical separation) respectively. Multiple-Path Particle Dosimetry (MPPD V2.11) model is used for prediction of deposition fraction calculations for the MCS deposition in different compartment of human respiratory tract. The activity concentration of 210 Po is founds 10.56 ± 2.46 mBq per cigarette for the tested cigarette brands. 210 Po size distribution indicates most of this associates with fine fraction (Dp < 2.23 μm) of cigarette smoke. The committed annual effective dose to smokers (smoking on an average 20 cigarette a day), considering the 210 Po and 210 Pb concentrations (assuming it is in secular equilibrium with 210 Po) in MCS, was estimated between 0.22 and 0.40 mSv, with mean value of 0.30 mSv for tested cigarette brands. Considering the risk factor of fatal cancer due to radiation exposure of lung (exposure time of 30 years); the average collective estimated fatal cancer risk is estimated as 1.5 × 10 -4 due to 210 Po and 210 Pb exposure to smokers.

The purpose of the this study was to explore the development of commitment to change among leaders in the home help services during organizational change and to study this development in relation to workload and stress. During organizational change initiatives, commitment to change among leaders is important to ensure the implementation of the change. However, little is known of development of commitment of change over time. The study used a qualitative design with semi-structured interviews with ten leaders by the time an organizational change initiative was launched and follow-up one year later. Thematic content analysis was used to analyze the interviews. Commitment to change is not static, but seems to develop over time and during organizational change. At the first interview, leaders had a varied pattern reflecting different dimensions of commitment to change. One year later, the differences between leaders' commitment to change was less obvious. Differences in commitment to change had no apparent relationship with workload or stress. The data were collected from one organization, and the number of participants were small which could affect the results on workload and stress in relation to commitment to change. It is important to support leaders during organizational change initiatives to maintain their commitment. One way to accomplish this is to use management team meetings to monitor how leaders perceive their situation. Qualitative, longitudinal and leader studies on commitment to change are all unusual, and taken together, this study shows new aspects of commitment.

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.

This cross-sectional study explored the relationship between professional commitment and job satisfaction among nurses. A total of 132 registered nurses were recruited from a hospital in northern Taiwan. A self-reported structured questionnaire was used to collect data. Findings revealed significant differences among nurses in willingness to make an effort and their marital status, appraisal in continuing their careers, job level, and goals and values related to working shifts. Significant differences were found between inner satisfaction and work sector and marital status. Nurses' professional commitment was strongly related to job satisfaction; aspects of professional commitment explained 32% of the variance in job satisfaction. Study results may inform health care institutions about the importance of nurses' job satisfaction and professional commitment so hospital administration can improve these aspects of organizational environment. © 2015 The Author(s).

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

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

PubMed

Berberoglu, Aysen

2018-06-01

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.

Nurses organizational commitment: the discriminating power of gender.

2007-01-01

The study of the organizational commitment has risen interest within the organization's researchers, who have been trying to understand the intensity and stability of the individual's dedication to the organization. The interest that this construct has raised is based on the idea of the existence of an association of the organizational commitment with variables considered important to the increase of the organizational effectiveness and productivity. The aim of this article is to describe organizational commitment, in its affective, normative, and continuance dimensions, from nurse practitioners, and to analyze the differences of that commitment regarding gender. Data were collected by questionnaire. The sample is constituted by nurse practitioners who develop their professional activity in 6 Portuguese hospitals. Data were analyzed using means, standard deviation, and independent samples t test. The sample consists of 1201 nurses. The organizational commitment of the studied nurses is, on average, 2.87+/-0.69 (in 5-point scale). When we make an analysis regarding gender, we verify that the organizational commitment is higher in women, being the difference statistically significant (t = -2.07; P < .05). There are different levels of commitment in male and female nurses, and it is higher in all dimensions in female nurses; however, the difference is only significant to the organizational and continuance commitment.

Organisational values and organisational commitment: do nurses' ethno-cultural differences matter?

To examine the association between perceived organisational values and organisational commitment among Israeli nurses in relation to their ethno-cultural background. Differences and the discrepancy between individuals' organisational values and those of their organisational culture are a potential source of adjustment difficulties. Organisational values are considered to be the bond of the individual to their organisation. In multicultural societies, such as Israel, the differences in perception of organisational values and organisational commitment may be reflected within workgroups. Data were collected using a questionnaire among 106 hospital nurses. About 59.8% of the sample were Israeli-born. A positive correlation was found between organisational values and organisational commitment. Significant differences were found in organisational values and organisational commitment between Israeli-born-, USSR-born- and Ethiopian-born nurses. The socio-demographic profile modified the effect of organisational values on organisational commitment: when the nurse was male, Muslim, religiously orthodox and without academic education, the effect of organisational values on organisational commitment was higher. Findings confirm the role of culture and ethnicity in the perception of organisational values and the level of organisational commitment among nurses. Assessing ethno-cultural differences in organisational values and organisational commitment provides a fuller understanding of nurses' ability to adjust to their work environment and helps nurse managers devise means to increase nurses' commitment. © 2012 John Wiley & Sons Ltd.

Moderating effects of nurses' organizational support on the relationship between job satisfaction and organizational commitment.

Chang, Ching-Sheng

2015-06-01

The aim was to investigate whether job satisfaction enhances organizational commitment among nursing personnel while exploring whether organizational support perception has a moderating effect on the relationship between their job satisfaction and organizational commitment. A cross-sectional survey was sent to 400 nurses; 386 valid questionnaires were collected, with a valid response rate of 96.5%. According to the research findings, nurses' job satisfaction has a positive and significant influence on organizational commitment. Results also indicated that the moderating effect of nurses' organizational support perception on the relationship between their job satisfaction and organizational commitment was stronger for high organizational support perception than it was for low organizational support perception. This study suggests that organizational support perception will develop a sense of belonging, and this will help improve nurses' job satisfaction and organizational commitment. This kind of relationship is rarely discussed in the research literature, and it can be applied for human resources management of nursing staff. © The Author(s) 2014.

2012-01-01

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

Cesium-137 body burdens in Norwegian Lapps, 1965-1983.

Westerlund, E A; Berthelsen, T; Berteig, L

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.

Capstone Depleted Uranium Aerosol Biokinetics, Concentrations, and Doses

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

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

Creative work environments in sport organizations: the influence of sexual orientation diversity and commitment to diversity.

PubMed

Cunningham, George B

2011-01-01

Drawing from creative capital theory, the purpose of this study was to examine the degree to which sexual orientation diversity and commitment to diversity were predictive of workplaces that fostered creativity. Data were collected from 653 senior level athletic administrators and aggregated to the athletic department level of analysis (n = 199). Moderated regression indicated that sexual orientation diversity did not influence the presence of a creative work environment. There was however, a significant sexual orientation diversity × commitment to diversity interaction. When commitment to diversity was high, there was a positive association between sexual orientation diversity and a creative work environment; on the other hand, when commitment to diversity was low, the aforementioned relationship was negative. Results provide support for the notion that all diversity forms can be a source of enrichment and understanding, thereby benefiting the workplace.

Survey of distribution of seasonal influenza vaccine doses in 201 countries (2004-2015): The 2003 World Health Assembly resolution on seasonal influenza vaccination coverage and the 2009 influenza pandemic have had very little impact on improving influenza control and pandemic preparedness.

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.

Mazerolle, Stephanie M.; Eason, Christianne M.; Pitney, William A.

2015-01-01

Context: Professional commitment simply describes one's obligation to his or her work. For athletic trainers (ATs), the demanding work environment and job expectations may affect their characterization of professional commitment. Our breadth of knowledge regarding professional commitment within athletic training is narrow. Objective: To evaluate the professional commitment of ATs in the collegiate setting. Design: Qualitative study. Setting: Collegiate. Patients or Other Participants: Thirty-three Board of Certification-certified ATs employed in the collegiate setting (National Collegiate Athletic Association Division I = 11, Division II = 9, Division III = 13) with an average of 10 ± 8 years of clinical experience volunteered. Data saturation guided the total number of participants. Data Collection and Analysis: Online journaling via QuestionPro was completed by all participants. Multiple-analyst triangulation and peer review were conducted for data credibility. Analysis followed a general inductive method. Results: Four themes speak to the factors that negatively affect ATs' professional enthusiasm and commitment: (1) life stage, (2) work overload, (3) organizational climate, and (4) human resources. The latter 3 speak to the effect the workplace can have on ATs' professional commitment, and the first speaks to the effect outside responsibilities can have. Conclusions: Our results suggest that several of the factors that negatively influence the professional commitment of collegiate ATs are modifiable organizational components. Developing resiliency strategies at the individual and organizational levels may help to facilitate improved professional commitment for the AT. PMID:25761133

According to Hochschild's (1983. The Managed Heart. Berkeley: University of California Press) classification of emotional labour, nursing staff express high emotional labour. This paper investigates how nursing staff influence job satisfaction and organizational commitment when they perform emotional labour. This paper examines the relationship between emotional labour, job satisfaction, and organizational commitment from the perspective of nursing staff. A questionnaire survey was carried out to explore these interrelationships. Teaching hospital in Taiwan. Questionnaires were distributed to 500 nursing staff; 295 valid questionnaires were collected and analysed-a 59% response rate. The questionnaires contained items on emotional labour, job satisfaction, and organizational commitment as well as some basic socio-demographics. In addition, descriptive statistics, correlation and linear structure relation (LISREL) were computed. Emotional display rule (EDR) was significantly and negatively related to job satisfaction. Surface acting (SA) was not significantly related to job satisfaction but demonstrated a significantly negative relationship with organizational commitment. Deep acting (DA) significantly and positively correlated with job satisfaction but demonstrated no significance with organizational commitment. The variety of emotions required (VER) was not significantly related to job satisfaction; frequency and duration of interaction (FDI) and negatively related to job satisfaction; and job satisfaction significantly and positively correlated with organizational commitment. We found that some dimensions of emotional labour significantly relate to job satisfaction. Job satisfaction positively affects organizational commitment and has an intervening effect on DA and organizational commitment.

Predictors of career commitment and job performance of Jordanian nurses.

2008-04-01

Few studies focused on nurses' career commitment and nurses' job performance. This research aimed at studying variables of nurses' career commitment and job performance, and assessing the relationship between the two concepts as well as their predictors. A survey was used to collect data from a convenient sample of 640 Registered Nurses employed in 24 hospitals. Nurses 'agreed' to be committed to their careers and they were performing their jobs 'well'. As a part of career commitment, nurses were willing to be involved, in their own time, in projects that would benefit patient care. The highest and lowest means of nurses' job performance were reported for the following aspects: leadership, critical care, teaching/collaboration, planning/evaluation, interpersonal relations/communications and professional development. Correlating of total scores of nurses' career commitment and job performance revealed the presence of a significant and positive relationship between the two concepts. Stepwise regression models revealed that the explained variance in nurses' career commitment was 23.9% and that in nurses' job performance was 29.9%. Nurse managers should promote nursing as a career and they should develop and implement various strategies to increase nurses' career commitment and nurses' job performance. These strategies should focus on nurse retention, staff development and quality of care. Nurses' career commitment and job performance are inter-related complex concepts that require further studies to understand, promote and maintain these positive factors in work environments.

To examine the relationships between acculturation, collectivist orientation and organisational commitment among Asian nurses in US hospitals. Few studies have explored these three variables together in the same study and examined their statuses and mutual relationship among Asian nurses in Western hospitals. The study was a cross-sectional design using snowball sampling. A total of 195 Asian nurses participated. The collectivist orientation scale, organisational commitment questionnaire and acculturation factors were used to collect data. Pearson correlation, anova and regression were used to analyse the data. Most participants were female Filipinos with a mean age of 39.92 and a bachelor's degree and stayed in the USA for 13.35 years. They used and preferred to use both their mother language and English, identified themselves as Oriental or Asian and culturally, viewed themselves as very or mostly Asian. Participants scored high on collectivism and commitment. Collectivism was significantly correlated with commitment but did not mediate acculturation factors and commitment. To increase Asian nurses' commitment, it is important that administrators understand their cultural values and provide them with a cultural competent and sensitive environment. Healthcare administrators can increase Asian nurses' commitment through understanding their needs and attitudes toward their job and organisation. © 2012 Blackwell Publishing Ltd.

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

2015-04-01

The purpose of this study was to examine the main and interaction effects of perceived organisational support, span of control and leadership rank on novice nurse leaders' organisational commitment. As nurse leaders' organisational commitment is eroded at times of healthcare restructuring, it is important to study factors associated with organisational commitment. Cross-sectional data from 69 novice nurse leaders, collected via mailed surveys at two time points, were analysed using hierarchical regression. The findings supported our hypotheses about the positive effect of perceived organisational support, the positive effect of leadership rank and the negative effect of span of control on novice nurse leaders' organisational commitment. In addition, perceived organisational support was shown to moderate the negative effect of span of control on novice nurse leaders' organisational commitment at time 2. Organisational strategies aimed at supporting nurse leaders, and attention to span of control, are required to enhance the organisational commitment of novice nurse leaders. Nurse leaders with a wide span of control, in particular those with little leadership experience, need to adopt leadership strategies that maximise their effectiveness, such as organising smaller work groups or teams within their wide span of control. © 2013 John Wiley & Sons Ltd.

To investigate the effect of some psychosocial variables on nurses' job satisfaction. Nurses' job satisfaction is one of the most important factors in determining individuals' intention to stay or leave a health-care organisation. Literature shows a predictive role of work climate, professional commitment and work values on job satisfaction, but their conjoint effect has rarely been considered. A cross-sectional questionnaire survey was adopted. Participants were hospital nurses and data were collected in 2011. Professional commitment and work climate positively predicted nurses' job satisfaction. The effect of intrinsic vs. extrinsic work value orientation on job satisfaction was completely mediated by professional commitment. Nurses' job satisfaction is influenced by both contextual and personal variables, in particular work climate and professional commitment. According to a more recent theoretical framework, work climate, work values and professional commitment interact with each other in determining nurses' job satisfaction. Nursing management must be careful to keep the context of work tuned to individuals' attitude and vice versa. Improving the work climate can have a positive effect on job satisfaction, but its effect may be enhanced by favouring strong professional commitment and by promoting intrinsic more than extrinsic work values. © 2013 John Wiley & Sons Ltd.

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.

Religious Commitment and Well-Being in College Students: Examining Conditional Indirect Effects of Meaning in Life.

PubMed

Dar, Kaiser Ahmad; Iqbal, Naved

2017-12-29

There is systematic and quantitative evidence that religious commitment is associated with indicators of well-being, such as positive emotions and moods, absence of negative emotions, and satisfaction with life; however, researchers remain far from a consensus regarding which mechanisms may account for these observed relationships. Although religious commitment influences well-being through many different mechanisms, meaning in life is probably the predominant one. Thus, we examined the bidimensional conceptualization of meaning in life as a potential mechanism between religious commitment and well-being. The study was cross-sectional in nature. Survey data were collected from 92 college students, aged 17-21. A battery of self-report measures was used for tapping religious commitment, well-being, and meaning in life. Even though presence of meaning, search for meaning, religious commitment, and well-being correlated moderately with each other, presence of meaning carried a substantial proportion of variance in predicting well-being for girls/women. This study suggests that religious commitment influences a person's sense of meaning in life, which, in turn, influences her/his well-being. And, we hope that these results encourage professionals to explore with their clients the fundamental questions of meaning and purpose in life.

Safety climate and safety behaviors in the construction industry: The importance of co-workers commitment to safety.

There is growing empirical evidence that as safety climate improves work site safety practice improve. Safety climate is often measured by asking workers about their perceptions of management commitment to safety. However, it is less common to include perceptions of their co-workers commitment to safety. While the involvement of management in safety is essential, working with co-workers who value and prioritize safety may be just as important. To evaluate a concept of safety climate that focuses on top management, supervisors and co-workers commitment to safety, which is relatively new and untested in the United States construction industry. Survey data was collected from a cohort of 300 unionized construction workers in the United States. The significance of direct and indirect (mediation) effects among safety climate and safety behavior factors were evaluated via structural equation modeling. Results indicated that safety climate was associated with safety behaviors on the job. More specifically, perceptions of co-workers commitment to safety was a mediator between both management commitment to safety climate factors and safety behaviors. These results support workplace health and safety interventions that build and sustain safety climate and a commitment to safety amongst work teams.

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.

Rodwell, John; Gulyas, Andre

2013-12-01

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.

People differ considerably in the way in which they express and experience their nursing careers. The positive effects associated with having a calling may differ substantially based on individuals' abilities to live out their callings. In a working world where many individuals have little to no choice in their type of employment and thus are unable to live out a calling even if they have one, the current study examined how perceiving a calling and living a calling interacted to predict organizational commitment, organizational citizenship behavior, and job stress with career commitment mediating the effect of the interactions on the three outcome variables. The purpose of the study is to investigate the mediating effect of career commitment between the relationships of calling and (a) nurses' attitudes (organizational commitment), (b) behaviors (organizational citizenship behavior), and (c) subjective experiences regarding work (job stress). Using a descriptive exploratory design, data were collected from 332 registered nurses working in Pakistani hospitals. Descriptive analysis and hierarchical regression analysis were used for data analysis. Living a calling moderated the effect of calling on career commitment, organizational citizenship behavior, and job stress, and career commitment fully mediated the effect of calling on organizational commitment, organizational citizenship behavior, and job stress. Increasing the understanding of calling, living a calling, and career commitment may increase nurses' organizational commitment and organizational citizenship behavior and decrease job stress. The study provided evidence to help nursing managers and health policy makers integrate knowledge and skills related to calling into career interventions and help nurses discover their calling.

Background: A nurse’s commitment is the most important factor that influences her performance and depends on other variables. The purpose of this research was to study the relationship between length of service of the nurses with the amount of occupational commitment and organizational commitment. Methods: From Winter 2012 to Spring 2013, 266 nurses were chosen in selected hospitals of Social Security Organization (SSO). These nurses were randomly categorized into six different classes of service records including < 5, 5-9, 10-14, 15-19, 20-24, and 25-29 years. The length of service is related to the organizational, occupational, affective, continuance, and normative commitment. The data were collected and analyzed. Results: Generally 84% of the responders were women and the rest were men of which 95% had a bachelor’s degree and the rest had higher academic degrees. The length of service in 81% of nurses was <15 years and 19% were higher than 15 years. Significant correlation were seen between continuance and occupational commitments and length of service (r=0.23, P=0.04 and r=-0.26, P=0.02, respectively). There were not any significant differences regarding organizational, affective and normative commitments (P=0.12, P=0.33, P=0.47, respectively). Conclusion: The results show that the length of service was related to continuance and occupational commitment. So pre-retirement of the nurses after 20 years of work can result in an increase in average commitment of employees. PMID:24778784

Work-Family Conflict, Perceived Organizational Support and Professional Commitment: A Mediation Mechanism for Chinese Project Professionals

PubMed Central

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.

Professional responsibility, rewards and respect, and time for rejuvenation are factors supporting professional commitment for athletic trainers (ATs) in the high school setting. The inherent complexities of an occupational setting can mitigate perceptions of professional commitment. Thus far, evidence is lacking regarding professional commitment for ATs in other occupational settings. To extend the literature on professional commitment of the AT to the collegiate setting. Qualitative study. Collegiate. Thirty-three Board of Certification-certified ATs employed in the collegiate setting (National Collegiate Athletic Association Division I = 11, Division II = 9, Division III = 13) with an average of 10 ± 8 years of clinical experience volunteered. Data saturation guided the total number of participants. Online journaling via QuestionPro was used to collect data from all participants. Two strategies, multiple-analyst triangulation and peer review, were completed to satisfy data credibility. Data were evaluated using a general inductive approach. Likert-scale data revealed no differences regarding levels of professional commitment across divisions. Two themes emerged from the inductive-content analysis: (1) professional responsibility and (2) coworker support. The emergent theme of professional responsibility contained 4 subthemes: (1) dedication to advancing the athletic training profession, (2) ardor for job responsibilities, (3) dedication to the student-athlete, and (4) commitment to education. Our participants were able to better maintain their own professional commitment when they felt their coworkers were also committed to the profession. The collegiate ATs investigated in this study, regardless of division, demonstrated professional commitment propelled by their aspiration to advance the profession, as well as their dedication to student-athletes and athletic training students. Maintaining commitment was influenced by a strong sense of coworker support.

To investigate employee-reported benefits of participation, employee organizational commitment, and health-related behaviors and body mass index (BMI) following implementation of a comprehensive workplace health promotion (WHP) program. State government employees from Tasmania, Australia, completed surveys in 2010 (n = 3408) and 2013 (n = 3228). Repeated cross-sectional data were collected on sociodemographic, health, and work characteristics. Participation in WHP activities, employee-reported organizational commitment, and benefits of participation were collected in 2013. Respondents who participated in multiple activities were more likely to agree that participation had motivated them, or helped them to address a range of health and work factors (trends: P < 0.05). There were significant associations between participation and employee organizational commitment. No differences were observed in health-related behaviors and BMI between 2010 and 2013. Healthy@Work (pH@W) was either ineffective, or insufficient time had elapsed to detect a population-level change in employee lifestyle factors.

Engagement in activism is related to several aspects of social development in adolescence and emerging adulthood. Therefore, it is important to examine the correlates of different forms of activism, such as feminist collective action, among all youth. However, previous research has not investigated young sexual-minority women's engagement with feminist collective action. This study examined predictors of college-aged heterosexual and sexual-minority women's commitment to and participation in feminist activism. Sexual orientation, number of years in college, social support, experiences with discrimination, and gender identity were tested as predictors of commitment to and participation in feminist activism with a sample of 280 college-aged women (173 heterosexuals and 107 sexual minorities). Similar predictors were related to both commitment to and participation in feminist activism. However, for sexual-minority women, but not heterosexual women, the number of years in college was correlated with participation in feminist activism. Young sexual-minority women reported more participation in feminist activism than did heterosexual women, even after controlling for social support, discrimination, and gender identity.

Does Witnessing Animal Cruelty and Being Abused During Childhood Predict the Initial Age and Recurrence of Committing Childhood Animal Cruelty?

Browne, John A; Hensley, Christopher; McGuffee, Karen M

2017-12-01

The goal of the current study was to examine the association between demographic characteristics and childhood experiences on the respondents' age of committing childhood animal cruelty and its recurrency. Using data collected from 257 male inmates at a Southern medium-security state prison, the current study seeks to replicate a study by Hensley, Tallichet, and Dutkiewicz. Results revealed that those respondents who were physically abused as children reported engaging in recurrent animal cruelty. The younger the age of respondent for first witnessing animal cruelty, the sooner his initiation to hurting and killing animals occurred. In addition, those who reported witnessing a parent commit acts of animal abuse reported that they committed animal abuse themselves at an older age, while those who witnessed a brother/sister commit animal abuse reported engaging in it at an earlier age. Therefore, physical abuse and witnessing primary socializers engage in animal abuse seem to be important in understanding the respondents' age of onset and repeated childhood animal cruelty.

Introduction Nursing care encompasses physical, emotional, mental and social needs, in order to improve a patient’s health and wellbeing. Caring is the central core and the essence of nursing. The important issue of care is access to proper care and increasing patients’ satisfaction. Job performance of nurses is affected by many factors including organizational commitment. This study aimed to determine the relationship between organizational commitment and nurses caring behavior. Methods In this cross-sectional study, 322 nurses from selected Hospitals of Shahid Beheshti University of Medical Sciences in Tehran were randomly selected and enrolled in the study in 2015. The self-reported data by nurses were collected through demographic characteristics questionnaire, Meyer & Allen organizational commitment model and Caring Behavior Inventory (CBI). Data were analyzed with SPSS statistical software version 20, using t-test and ANOVA. Findings The majority of nurses (63%) were female. The mean score and standard deviation of organizational commitment and caring behavior of nurses were 74.12±9.61 and 203.1±22.46, respectively. The results showed a significantly positive correlation between organizational commitment and caring behavior (p=0.001). Conclusion In this study the caring behavior of nurses with higher organizational commitment were significantly better than the others. Managers and nurse leaders should pay more attention to improve organizational commitment of nurses, in order to improve nurses’ performance. PMID:28894543

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.

Dewji, S.; Hertel, N.; Ansari, A.

2017-01-01

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.

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.

2017-11-28

Suicide and suicide attempts represent a worldwide health priority. The aim of our study was to describe the epidemiological and clinical characteristics of young suicide attempters among a clinical population and to assess their potential evolution over a period of11 years. We conducted a descriptive retrospective study among a clinical population of suicide attempters referred to the child psychiatric department of the Razi hospital, the inpatient reference department in the north and center of Tunisia, between January 2005 and December 2015. Based on the WHO definition we considered as suicide attempts, "any deliberate act, without any fatal outcome, aimed at performing a gesture of violence on one's own person or to ingest a toxic substance or drugs at a dose higher than the dose recognized as therapeutic". We conducted collection of data from patient records based on a pre-established record with the following parameters: clinical study of patients including: socio-demographic data, clinical characteristics based on DSM 4 criteria and environmental factors including family history of psychiatric disorder, abuse, school difficulties and failure. The sample was composed of 159 patients having a mean age of 12.8 years with extremes from 5.8 to 17 years. It was composed of 74.2% girls and 25.8% boys. Medical intoxication was the most common mean (68.6%) followed by physical means (20.1%) and toxic products ingestion (12.6%). The suicide attempts were mainly non-premeditated (83.1%). Our patients reported a previous suicide attempt in 25.8% of cases. Chronic somatic disorders were found among 24.5% of our sample. Psychiatric disorders among children, parents, abuse, and school failure were found in respectively 48.4%, 50.6%, 37.1% and 13.4% of suicidal patients. Psychiatric disorders were dominated by depressive disorders and oppositional defiant disorders associated with conduct disorder. The chronological study highlighted significant modifications starting from 2013/2014, reflecting a recent trend: a significant decrease in suicidal age was found since the year 2015: children under 10 years of age, who constituted 8.4 % (n=10) of suicides during the period from (n=119), accounted for 20 % (n=32) of the patients enumerated in the year 2015 (P=0.045). We also found that the percentage of suicidal attempts committed in winter was higher from 2013 than in previous years (P=0.019). We also noted a significant increase in 2014 in the proportion of patients with a personal history of suicidal attempt when compared to previous years (P=0.045). The use of physical means became more frequent from 2013 (P=0.019). This is confirmed by comparing the suicide attempts prior to and from 2014 (P=0.007) or by comparing the suiced attempts committed in 2015 to the ones committed during the previous ten years (P=0.007). Finally, there was a statistically significant distribution of serious organic effects (coma) as a function of years: such complications were more frequent in the course of suicidal attempts committed after 2013 (P=0.009). Since 2013/2014 we found a recent trend characterized by more children among suicidals, more patients reporting a previous suicide attempt, more frequent use of physical means and a greater proportion of suicide attempts realized in winter. This raises the challenge for more research on the topic as well as new therapeutic interventions. Copyright © 2017 L'Encéphale, Paris. Published by Elsevier Masson SAS. All rights reserved.

The aim of this study was to examine the degree to which it is possible to predict job satisfaction in hospital nurses based on core self-evaluation and the nurses' professional commitment. Psychological constructs of nurses' professional commitment could predict a level of job satisfaction. A cross-sectional design was applied. Data were collected between April 2016 and November 2016 from 584 nurses of the University Hospital Osijek. Core Self-Evaluation Scale (CSES), Job Satisfaction Survey (JSS) and Nurses' professional commitment scale (NPCS) were administrated to the study participants. Confirmatory factor analyses were conducted to test the validity of each questionnaire. Structural equation modeling was used to test the prediction of nurses' professional commitment and core self-evaluation on job satisfaction. Nurses' professional commitment is variable, which functions as a mediator between predictor (CSE) and criterion variable (JS). As a mediator, it explains what the effect is, provided that correlations between all variables are significant. The correlation analyses reveal significant positive correlations between job satisfaction and core self evaluation (r = 0.441, p > 0.001) and also between job satisfaction and nurses' professional commitment (r = 0.464, p > 0.001). Furthermore, core self evaluation significantly and positively correlates with nurses' professional commitment (r = 0.402, p > 0.001). The results showed that nurses' professional commitment mediates the relationship between core self evaluation and job satisfaction. Bootstrap analysis showed that core self evaluation partially mediated the relationship between nurses' professional commitment and job satisfaction ( β = 0.78, p < 0.001**). The indirect effects of core self evaluation on job satisfaction through nurses' professional commitment was also significant (β = 0.17, p < 0.001**). Nurses who are more committed to their work, regardless of the structure of personality, have greater satisfaction in their work.

2015-01-01

The objective of this study is to identify relationships between three components of organizational commitment and organizational characteristics of nurses in the western and the eastern region of Nepal. A self-administrated questionnaire was used to collect data from 310 nurses currently working at various hospitals in the eastern and the western region of the country. The questionnaire included three sections namely 1) personal characteristics 2) organizational characteristics and 3) organizational commitments scale. Descriptive analysis and multiple regression analysis were performed to identify significance in various relationships. Out of the 240 completed questionnaires, 226 were found valid for analysis. The mean age was 27.4 years. For each depended variable affective, continuance and normative commitment, multiple regression analysis was performed with personal Characteristics and organizational characteristics as independent variables. All independent variables were found significantly related to each of the two dependent variables; affective commitment and normative commitment (R2 adjusted=0.24, p<0.01 and R2 adjusted=0.05, p<0.01 respectively). However, they were not significantly related to the continuance commitment. Both support from boss (β=0.138, p<0.05) and satisfaction with training (β=0.301, p<0.05) were found to be positive and significant with affective commitment. On the other hand, satisfaction with training (β=0.191, p<0.05) was also positive and significant with normative commitment. Since both support from boss and training program were found to be positive and significant with affective commitment, hospitals must encourage supervisors to provide more assistance to the subordinate nurses. Moreover, hospitals should develop more training programs to keep nurses motivated.

Ultralow Dose MSCT Imaging in Dental Implantology

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

This study was designed to identify the level of nurses' job satisfaction, occupational commitment and intent to stay among mainland Chinese nurses, to explore the relationship among them.   Little is known about the magnitude of Chinese nurses' intent to stay. Understanding the association among demographic characteristics and job satisfaction, occupational commitment and intent to stay among Chinese nurses is most important in a time of nurse shortages. Methods.  A descriptive correlation design was used to examine the relationship among variables related to intent to stay. Data were collected by a self-administered survey questionnaire from 560 nurses working in four large hospital facilities in Shanghai in 2009. The mean scores for nurses' job satisfaction, occupational commitment and intent to stay were 3·25(0·48), 3·11(0·40) and 3·56(0·65), respectively. Job satisfaction and occupational commitment were significantly related to intent to stay. A statistically significant positive correlation was found between occupational commitment and job satisfaction. Age and job position were significantly related to job satisfaction, occupational commitment and intent to stay. Levels of job satisfaction, occupational commitment and intent to stay reported by nurses in this study can be improved. Suggested strategies for improvement are: increasing salaries, decreasing workloads, modifying task structure, cultivating work passion and creating more professional opportunity for nurses' personal growth development and promotion. Enhancing nurses' job satisfaction and occupational commitment are vital to improve nurses' intent to stay and for strategies to address the nursing shortage. © 2011 Blackwell Publishing Ltd.

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.

The present study investigates the effect of perceived social support (PSS) and perceived religious endorsement (PRE) on career commitment (CC) of Saudi nurses. The investigation also extends to the moderating role of different demographic and organizational factors in the extent of PSS, and career commitment these nurses report. Data required for meeting these study objectives were collected from male and female Saudi nurses through a structured questionnaire. Multiple regressions using Partial Least Squares based Structural Equation Model, Smart-PLS version 3.0, and independent sample t-test using SPSS version 22.0, were used to analyze data. The study findings reveal that both perceived social support and perceived religious endorsement are important antecedents of career commitment of Saudi nurses. However, private-sector nurses are found to exhibit a significantly higher level of career commitment compared to their public-sector counterparts. Nurses with greater educational attainment perceive higher level of social support and express greater career commitment than their less educated peers. These findings suggest that nursing as a profession should be more openly discussed in both secular and religious contexts, to ensure an adequate level of respect and compassion on behalf of the public. In particular, endorsement from the individual nurses’ social networks is vital in maintaining their wellbeing and career commitment. Given the religious influence in all aspects of life in the Saudi society, the current practice of gender-based segregation in Saudi hospitals and clinics seems to be meaningful for sustaining the career commitment of the nurses.

To examine whether general practitioners (GP) working in primary health care have lower organizational commitment compared with physicians working in other health sectors. The authors also tested whether psychosocial factors (job demands, job control, and colleague consultation) explain these differences in commitment between GPs and other physicians. Cross-sectional postal questionnaire. Setting and participants. A postal questionnaire was sent to a random sample of physicians (n = 5000) drawn from the Finnish Association database in 2006. A total of 2841 physicians (response rate 57%) returned the questionnaire, of which 2657 (545 GPs and 2090 other physicians) fulfilled all the participant criteria. Organizational commitment was measured with two different indicators: intention to change jobs and low affective commitment. GPs were less committed to their organizations than other physicians. Work-related psychosocial factors (high job demands, low job control, and poor colleague consultation) were all significant risk factors for low organizational commitment. The evidence collected suggests that policies that reduce psychological demands, such as job demands and low control, may contribute to better organizational commitment and, thus, alleviate the shortages of physicians in primary care. Furthermore, giving GPs a stronger say in decisions concerning their work and providing them with more variety in work tasks may even improve the quality of primary care. The strategies for workplace development should focus on redesigning jobs and identifying GPs at higher risk, such as those with especially high job strain.

Previous Ingestion of Lactococcus lactis by Ethanol-Treated Mice Preserves Antigen Presentation Hierarchy in the Gut and Oral Tolerance Susceptibility.

Ethanol (EtOH) consumption is able to disturb the ovalbumin (OVA)-oral tolerance induction by interfering on the function of antigen presenting cells (APC), down-regulating dendritic cells (DCs) and macrophages and up-regulating B-lymphocytes and their function, which results in an overall allergic-type immune status. In this study, the potential of a priori administration of Lactococcus lactis (LL) in avoiding loss of oral tolerance in EtOH-treated mice was investigated. Female C57BL/6 mice received, by oral route, ad libitum wild-type (WT) LL or heat-shock protein producer (Hsp65) LL for 4 consecutive days. Seven days later, mice were submitted to short-term high-dose EtOH treatment. After 24 hours, stomach, intestine, spleen, mesenteric lymph nodes (mLN) specimens were collected for biomarkers analysis. Following EtOH-treatment protocol, a group of animals underwent single-gavage OVA-tolerance protocol and sera samples collected for antibody analysis. The ingestion of WT LL or Hsp65 LL is able to restore oral tolerance to OVA in EtOH-treated mice, by reducing local and systemic allergic outcomes such as gastric mast cells and gut-interleukin-4, as well as serum IgE. WT LL treatment prevents the decrease of mLN regulatory T cells induced by the EtOH treatment. Moreover, LL treatment preserves APC hierarchy and antigen presentation commitment in EtOH-treated mice, with conserved DC and macrophage activity over B lymphocytes in mLN and preserved macrophage activity over DC and B-cell subsets in the spleen. The present findings suggest that a priori ingestion of LL preserves essential mechanisms associated with oral tolerance induction that are disturbed by EtOH ingestion. Maintenance of mucosal homeostasis by preserving APC hierarchy and antigen presentation commitment could be associated with T-regulatory subset activities in the gastrointestinal tract.

Cohabitation and Intimate Partner Violence during Emerging Adulthood: High Constraints and Low Commitment.

PubMed

Manning, Wendy D; Longmore, Monica A; Giordano, Peggy C

2018-03-01

In recent years, a majority of young adults experience cohabitation. Nevertheless, cohabitation is a risk factor for intimate partner violence (IPV). Drawing on social exchange and commitment theory we analyzed young adults' IPV experiences using the recently collected (2011-2012) Toledo Adolescent Relationships Study data (n = 926). We found that sociodemographic characteristics, relationship commitment, quality, and constraints as well as prior experience with violence (in prior relationships and family of origin) were associated with IPV, but did not explain the association between cohabitation and IPV. We examined variation among individuals in cohabiting relationships to determine which cohabitors face the greatest risk of intimate partner violence. Serial cohabitors along with cohabitors who experienced both low commitment and high relational constraints experienced the greatest risk of IPV. These findings provided insights into the implications of cohabitation for the well-being of young adults.

This research explores the linking mechanisms and conditional processes underlying the relationship between psychological voice climate and individual change readiness. In accordance with the social identity theory, we argued that normative commitment would mediate the relationship between psychological voice climate and individual change readiness; furthermore, work engagement would moderate the proposed indirect effect. Two-wave survey data were collected from 187 full-time employees in a government-owned institute of research and development and were adopted for moderated mediation analysis. The results showed that normative commitment mediates the relationship between psychological voice climate and individual change readiness. Furthermore, work engagement strengthens the effect of psychological voice climate on individual change readiness in an indirect manner via normative commitment. Based on the findings, the theoretical implications and practical suggestions were discussed. PMID:29062294

To analyze if the combination of organizational climate and work commitment can predict return to work (RTW). This prospective Swedish study was based on 2285 participants, 19 to 64 years old, consecutively selected from the employed population, newly sick-listed for more than 14 days. Data were collected in 2008 through postal questionnaire and from register data. Among women, the combination of good organizational climate and fair work commitment predicted an early RTW with an adjusted relative risk of 2.05 (1.32 to 3.18). Among men, none of the adjusted variables or combinations of variables was found significantly to predict RTW. This study demonstrated the importance of integrative effects of organizational climate and individual work commitment on RTW among women. These factors did not predict RTW in men. More research is needed to understand the RTW process among men.

The relationship between investment in employee health and non-health outcomes has received little research attention. Drawing from social exchange and climate theory, the current study uses a multilevel approach to examine the implications of worksite health investment for worksite safety and health climate and employee safety compliance and commitment to the worksite. Data were collected from 1932 personnel working on 31 offshore installations operating in UK waters. Installation medics provided corporate workforce health investment details for 20 of these installations. The findings provide support for a strong link between health investment practices and worksite safety and health climate. The results also found a relationship between health investment practices and organizational commitment among employees. These results suggest that health investment practices are associated with committed workforces and climates that reflect a priority on health and safety. 2009 Elsevier Ltd. All rights reserved.

Committed dis(s)idents: participation in radical collective action fosters disidentification with the broader in-group but enhances political identification.

The present research examined the hypothesis that participation in radical, but not moderate, action results in disidentification from the broader in-group. Study 1 (N = 98) was a longitudinal study conducted in the context of student protests against tuition fees in Germany and confirmed that participation in radical collective action results in disidentification with the broader in-group (students) whereas participation in moderate collective action does not. Both types of action increased politicized identification. Study 2 (N = 175) manipulated the normativeness of different types of imagined collective actions in the same context and replicated this disidentification effect for radical actions, but only when this action mismatched the broader in-group's norms. This study also indicated that these effects were partially mediated by perceived lack of solidarity and perceived lack of commitment to the cause among the broader in-group. The implications of these findings for understanding radicalization within social movements are discussed.

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.

2013-01-01

Background A national survey of patient exposure from nuclear medicine diagnostic procedures was performed by Slovenian Radiation Protection Administration in order to estimate their contribution to the collective effective dose to the population of Slovenia. Methods A set of 36 examinations with the highest contributions to the collective effective dose was identified. Data about frequencies and average administered activities of radioisotopes used for those examinations were collected from all nuclear medicine departments in Slovenia. A collective effective dose to the population and an effective dose per capita were estimated from the collected data using dose conversion factors. Results The total collective effective dose to the population from nuclear medicine diagnostic procedures in 2011 was estimated to 102 manSv, giving an effective dose per capita of 0.05 mSv. Conclusions The comparison of results of this study with studies performed in other countries indicates that the nuclear medicine providers in Slovenia are well aware of the importance of patient protection measures and of optimisation of procedures.

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

PubMed

Edwards, Geoffrey W R; Priest, Nicholas D

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.

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 demanding nature of nursing work environments signals longstanding and growing concerns about nurses' health and job satisfaction and the provision of quality care. Specifically in health care settings, nurse leaders play an essential role in creating supportive work environments to avert these negative trends and increase nurse job satisfaction. The purpose of this study was to examine the relationship between structural empowerment and organizational commitment of nurses. 491 nurses working in Zanjan hospitals participated in this descriptive-correlational study in 2010. Tools for data collection were Meyer and Allen's organizational commitment questionnaire and "Conditions for Work Effectiveness Questionnaire-II" (CWEQ-II). Data was analyzed by SPSS16. The statistical tests such as variance analysis, t-test, pearson correlation coefficient and linear regression were used for data analysis. According to the findings, the perception of nurses working in hospitals on "Structural Empowerment" was moderate (15.98±3.29). Nurses believed "opportunity" as the most important element in structural empowerment with the score of 3.18 ±0.79. Nurses working in non-academic hospitals and in non-teaching hospitals had higher organizational commitment than others. There was a significant relationship between structural empowerment and organizational commitment. Generally, structural empowerment (relatively strong) correlates with nurses' organizational commitment. We concluded that a high structural empowerment increases the organizational commitment of nurses.

Causal relationship model between variables using linear regression to improve professional commitment of lecturer

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.

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.

This study examined which aspects of professional commitment can effectively retain nurses in the nursing profession. This study used a longitudinal design, simple random sampling, and two-wave data collection to survey and follow up a representative sample of 579 nurses for 1 year in a major medical center in northern Taiwan. Items measuring each aspect of professional commitment came from Meyer et al.'s scale. In the second wave, administrative data were culled to determine whether these nurses remain employed as nurses. Structural equation modeling is used to analyze the data. Analytical results indicate that continuance commitment predicts nurse retention in the nursing profession (path coefficient = 0.34, p < .01). Institutional efforts to improve continuance commitment (e.g., improved salary structures and enhanced professional development opportunities) likely retain nurses in the nursing profession. The findings of this study indicate the importance of continuance intention in retaining nurses. Nursing managers who face staff retention issues may consider making efforts to improve nurse salary and employer-sponsored benefits. © 2015 Sigma Theta Tau International.

Because nurses deliver care to patients on behalf of hospitals, hospitals should enhance the spontaneous organizational citizenship behaviors of front-line nurses to increase patient satisfaction and, hence, to increase the competitiveness of the hospital. However, a major gap in the literature is the lack of evidence-based studies of the correlations among job satisfaction, organizational commitment, and organizational citizenship behaviors in nursing personnel. Therefore, this study performed a cross-sectional survey of nurses in 1 large hospital in Taiwan; out of 400 questionnaires distributed, 386 valid questionnaires were collected, which was a valid response rate of 96.50%. The survey results revealed that organizational commitment has a significant positive effect on organizational citizenship behaviors (γ11 = 0.57, p < .01) and that job satisfaction has a significant positive moderating effect on the relationship between organizational commitment and organizational citizenship behaviors (Δχ2 = 26.397, p < .01). Therefore, hospitals can improve the job satisfaction of their nursing staff by improving perceived working satisfaction, interpersonal satisfaction, and remunerative satisfaction, which would then improve organizational commitment and organizational citizenship behaviors.

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.

This paper adopts an intergroup perspective on helping as collective action to explore the ways to boost motivation amongst people in developed countries to join the effort to combat poverty and preventable disease in developing countries. Following van Zomeren, Spears, Leach, and Fischer's (2004) model of collective action, we investigated the role of norms about an emotional response (moral outrage) and beliefs about efficacy in motivating commitment to take action amongst members of advantaged groups. Norms about outrage and efficacy were harnessed to an opinion-based group identity (Bliuc, McGarty, Reynolds, & Muntele, 2007) and explored in the context of a novel group-based interaction method. Results showed that the group-based interaction boosted commitment to action especially when primed with an (injunctive) outrage norm. This norm stimulated a range of related effects including increased identification with the pro-international development opinion-based group, and higher efficacy beliefs. Results provide an intriguing instance of the power of group interaction (particularly where strengthened with emotion norms) to bolster commitment to positive social change.

Evaluation of indoor radon equilibrium factor using CFD modeling and resulting annual effective dose

Rabi, R.; Oufni, L.

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.

Commit* to change? A call to end the publication of the phrase 'commit* suicide'.

PubMed

Nielsen, Emma; Padmanathan, Prianka; Knipe, Duleeka

2016-12-06

Background. Countering stigma is a fundamental facet of suicide prevention efforts.  Integral to this is the promotion of accurate and sensitive language.  The phrase 'commit* suicide' has prompted marked opposition primarily due to the connotations of immorality and illegality.  Methods. The study investigated the frequency of the use of the wordstem 'commit', in relation to self-harm and suicidal behaviours, in the three leading suicide-specific academic journals between 2000 and 2015.  Results. One third (34%) of articles published since the year 2000 used the word 'commit*' when describing an act of self-harm or suicide. Over half of these articles (57%) used the phrase on more than one occasion, with 6% using it more than 10 times in the same manuscript. The percentage of papers utilising the word 'commit*' has fluctuated over time, but there is a promising downward trend in the use of this phrase from 33% in 2000 to 13% in 2015 ( p < 0.001).  Discussion. We advocate for the implementation of publication requirements regarding the language used when discussing suicide. Whilst we call for collective responsibility amongst academics and clinicians, editors hold a unique position in ensuring that outdated, inaccurate and stigma-laden terms are expunged from the scientific literature.

Health care workers are exposed to several job stressors that can adversely affect their wellbeing. Workplace incivility is a growing organizational concern with the potential to create workplaces harmful to individuals' wellbeing and increase occupational health risks. Based on the Job Demands-Resources (JD-R) model, the purpose of the present study was to investigate the role of two resources (organizational empowerment and job control) on individuals' well-being (emotional exhaustion) and attitude at work (unit affective commitment). A total of 210 hospital workers completed a self-administered questionnaire that was used to measure organizational empowerment, workplace incivility, job control, exhaustion, and affective commitment. Data were collected in 2014. Data were examined via linear regression analyses. The results showed that workplace incivility was positively related to emotional exhaustion and negatively related to affective commitment. Workplace empowerment was positively related to affective commitment and negatively related to emotional exhaustion. Furthermore, the positive relationship between workplace empowerment and affective commitment was significantly moderated by job control. Our results found support for the JD-R model. Specifically, results showed the buffering effect of job control in the relationship between empowerment and affective commitment. Our findings may concretely contribute to the stress literature and offer additional suggestions to promote healthy workplaces.

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.

Background: Self esteem (SE) and organizational commitment (OC) have significant impact on the quality of work life. Aim: 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). Methods: 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. Results: 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. Conclusion: 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. PMID:25716374

2011-01-01

This study aims to investigate the mediating role of organizational subculture between job satisfaction, organizational commitment (dependent variables) and leadership, culture (independent variables) in health care organizations. A survey on nurses from 26 wards from various types of hospital was used. A total of 251 usable returns were collected for the analysis (i.e. response rate of 63 per cent). Structural equation analysis was conducted to obtain the best fit model and to determine the direction of the causal effect between job satisfaction and commitment, and the role of subculture as a mediating variable, between commitment of its other antecedents. Comparisons with alternative models confirmed satisfaction as an antecedent of commitment and the role of subculture as a mediating variable. The results of this study contribute to the clarification of the causal relations of the antecedents of commitment, and highlight the important role of local leadership and subculture in determining employees' job satisfaction and commitment. The results of this study should not be generalized to other industries and other national cultural context. Furthermore, a longitudinal study may be necessary to determine the causal relationship of variables used in this study. The findings could provide managers with valuable insight to focus their limited resources on improving the level of organizational commitment via the mediating role of organizational culture. The research findings provide managers with a new lens to examine organizational culture using the three perspectives of: bureaucratic, supportive, and innovative. Furthermore, the results could renew interest in developing other organizational subculture models that determine the relationship between organizational subculture and commitment

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.

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.

Is organizational justice climate at the workplace associated with individual-level quality of care and organizational affective commitment? A multi-level, cross-sectional study on dentistry in Sweden.

Berthelsen, Hanne; Conway, Paul Maurice; Clausen, Thomas

2018-02-01

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.

The impact of workplace spirituality dimensions on organisational citizenship behaviour among nurses with the mediating effect of affective organisational commitment.

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.

Electronic medical record system (EMRS) is a valuable system for safe access to the patient's data and increases health care quality. Manpower is one of the requirements for EMRS, among which manager is the most important person in any hospital. Taking into account manager's positive attitude and good commitments, EMRS will be implemented successfully. As such, we decided to assess manager's attitude and commitment toward EMRS in Isfahan hospitals in the year of 2014. This article aimed to determine the hospital managers' attitude and commitment toward the implementation of EMRS. The present article is an applied analytic study. Research society consisted of the managers of all the hospitals in Isfahan that include hospitals affiliated to Isfahan University of Medical Sciences, private, and social security hospitals. This study was done in 2014. Data collection tools included a questionnaire for which reliability and validity were determined. Data were analyzed by means of SPSS 20. Average score for the managers' attitude toward EMRS in the city of Isfahan was 77.5 out of 100 and their average score for commitment was 74.7. Manager's attitude in social security hospitals was more positive than the private and governmental ones (83.3%). In addition, the amount of commitment by the managers in social security hospitals was higher than the same in private and governmental hospitals (86.6%). At present, managers' attitude and commitment in Isfahan hospitals toward EMRS are very high and social security hospitals show more readiness in this respect.

Lack of effect of a granulocyte proliferation inhibitor or their committed precursor cells.

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.

Why Don't I Help You? The Relationship between Role Stressors and Helping Behavior from a Cognitive Dissonance Perspective.

PubMed

Zhang, Li; Xia, Ying; Liu, Baowei; Han, Lu

2017-01-01

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.

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. PMID:29416516

Different fits satisfy different needs: linking person-environment fit to employee commitment and performance using self-determination theory.

Integrating and expanding upon the person-environment fit (PE fit) and the self-determination theory literatures, the authors hypothesized and tested a model in which the satisfaction of the psychological needs for autonomy, relatedness, and competence partially mediated the relations between different types of perceived PE fit (i.e., person-organization fit, person-group fit, and job demands-abilities fit) with employee affective organizational commitment and overall job performance. Data from 163 full-time working employees and their supervisors were collected across 3 time periods. Results indicate that different types of PE fit predicted different types of psychological need satisfaction and that psychological need satisfaction predicted affective commitment and performance. Further, person-organization fit and demands-abilities fit also evidenced direct effects on employee affective commitment. These results begin to explicate the processes through which different types of PE fit relate to employee attitudes and behaviors. (c) 2009 APA, all rights reserved.

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.

2012-01-01

This mixed methods study examined social justice commitments of counseling psychology graduate trainees. In the quantitative portion of the study, a national sample of trainees (n = 260) completed a web-based survey assessing their commitments to social justice and related personal and training variables. Results suggested that students desired greater social justice training than what they experienced in their programs. In the qualitative portion, we used a phenomenological approach to expand and elaborate upon quantitative results. A subsample (n = 7) of trainees who identified as strong social justice activists were interviewed regarding their personal, professional, and training experiences. Eleven themes related to participants' meanings of and experiences with social justice emerged within 4 broad categories: nature of social justice, motivation for activism, role of training, and personal and professional integration. Thematic findings as well as descriptive statistics informed the selection and ordering of variables in a hierarchical regression analysis that examined predictors of social justice commitment. Results indicated that trainees' perceptions of training environment significantly predicted their social justice commitment over and above their general activist orientation and spirituality. Findings are discussed collectively, and implications for training and future research are provided. (c) 2012 APA, all rights reserved.

To analyze the relationships between the situational leadership styles, staff nurse job characteristic with job satisfaction and organizational commitment of head nurses working in hospitals under the jurisdiction of the Royal Thai Army The cross-sectional analytical study was conducted in 128 head nurses working in hospitals under the jurisdiction of the Royal Thai Army. Data were collected by mailed questionnaires. A total of 117 completed questionnaires (91.4%) were received for analysis. Statistical analysis was done using Pearson's Product Moment Correlation Coefficient. It was found that situational leadership styles were not correlated with job satisfaction and organizational commitment of head nurses. Staff nurse job characteristics had a low level of positive correlation with job satisfaction and organizational commitment of head nurses at 0.05 level of significance (r = 0.202 and 0.189 respectively). The hospital administrators should formulate policy to improve working system, human resource management and formulate policies and strategies based on situational leadership. In addition, they should improve the characteristics of staff nurse job by using surveys to obtain job satisfaction and organizational commitment.

The purpose of this study was to investigate the casual relationship between nurses' social capital and turnover intention and to verify the goodness of fit between a hypothetical model and actual data in order to suggest the best model. This survey was conducted with 315 nurses working in general hospitals in Seoul. Data were collected from December 1 to December 30, 2011, and analyzed using SPSS Windows 18.0 and AMOS 16.0. Nurses' social capital was found to have a direct effect on reducting organization cynicism and increasing organizational commitment. Nurses' organizational cynicism and organizational commitment were found to have a direct effect on turnover intention, but social capital did not have a direct effect on turnover intention. However, social capital had a partial and indirect effect on turnover intention through mediating organizational cynicism and organizational commitment. Results of this study indicate that nurse managers should put increased effort in reducing nurses' organizational cynicism and improving their organizational commitment, two contrary parameters. At the same time managers need to develop plans to establish social capital more efficiently so that nurses have lower turnover intention.

Objective Burnout syndrome can significantly reduce the performance of health workers. Although many factors have been identified as antecedents of burnout, few studies have investigated the role of organisational commitment in its development. The purpose of the present study was to examine the relationships between subdimensions of burnout syndrome (emotional exhaustion, depersonalisation and personal accomplishment) and subdimensions of organisational commitment (affective commitment, continuance commitment and normative commitment). Methods The present study was a cross-sectional survey of physicians and other healthcare employees working in the Ministry of Health Ordu University Education and Research Hospital. The sample consisted of 486 healthcare workers. Data were collected using the Maslach Burnout Inventory and the Organisation Commitment Scale, and were analysed using the canonical correlation approach. Results The first of three canonical correlation coefficients between pairs of canonical variables (Ui , burnout syndrome and Vi, organisational commitment) was found to be statistically significant. Emotional exhaustion was found to contribute most towards the explanatory capacity of canonical variables estimated from the subdimensions of burnout syndrome, whereas affective commitment provided the largest contribution towards the explanatory capacity of canonical variables estimated from the subdimensions of organisational commitment. Conclusions The results of the present study indicate that affective commitment is the primary determinant of burnout syndrome in healthcare professionals. What is known about the topic? Organisational commitment and burnout syndrome are the most important criteria in predicting health workforce performance. An increasing number of studies in recent years have clearly indicated the field's continued relevance and importance. Conversely, canonical correlation analysis (CCA) is a technique for describing the relationship between two variable sets simultaneously to produce both structural and spatial meaning. What does this paper add? To our knowledge, CCA has not been used to determine the relationships between burnout and organisational commitment of physicians and other healthcare staff. Accordingly, the present study adds information regarding the relationship between burnout and organisational commitment variables determined using CCA. This analysis is used to describe the relationship between two variable sets simultaneously and allows for an easy method of interpretation. What are the implications for practitioners? Burnout syndrome is a major threat to both the health workforce and its organisations. In addition, it affects the quality and effectiveness of health care. Thus, the findings of the present study offer a solid foundation from which actions to decrease burnout levels in healthcare professionals can be implemented by successfully increasing levels of organisational commitment.

The purpose of this study was to investigate the relationships among employee organizational commitment, organizational trust, job satisfaction and employees' perceptions of their immediate supervisors' transformational leadership behaviors in Turkey. First, this study examined the relationships among organizational commitment, organizational trust, job satisfaction and transformational leadership in two Turkish public hospitals. Second, this investigation examined how job satisfaction, organizational trust and transformational leadership affect organizational commitment. Moreover, it was aimed to investigate how organizational commitment, job satisfaction and transformational leadership affect organizational trust. A quantitative, cross-sectional method, self-administered questionnaire was used for this study. Eight hundred four employees from two public hospitals in Turkey were recruited for collecting data. The overall response rate was 38.14%. The measurement instruments of survey were the Job Satisfaction Survey (developed by P. Spector), the Organizational Commitment Questionnaire (developed by J. Meyer and N. Allen), the Organizational Trust Inventory-short form (developed by L. Cummings and P. Bromiley) and the Transformational Leadership Inventory (TLI) (developed by P. M. Podsakoff). Five-point Likert scales were used in these measurement instruments. Correlation test (the Pearson's rank test) was used to examine relationships between variables. Also, multiple regression analysis was used to determine the regressors for organizational commitment and organizational trust. There were significant relationships among overall job satisfaction, overall transformational leadership and organizational trust. Regression analyses showed that organizational trust and two job satisfaction dimensions (contingent rewards and communication) were significant predictors for organizational commitment. It was found that one transformational leadership dimension (articulating a vision), two job satisfaction dimensions (pay and supervision) and two organizational commitment dimensions (affective commitment and normative commitment) were significant regressors for organizational trust. There is a lack of research in the health organizations regarding organizational commitment, organizational trust, job satisfaction and transformational leadership. The investigator of the proposed study intends to add to the literature and intends to prove that the proposed study would be important for healthcare organizations. A number of specific measures should be undertaken to reduce factors that negatively affect organizational commitment, organizational trust and job satisfaction of hospital personnel and to improve transformational leadership behaviors of hospital administrators.

2014-02-01

Many psychological processes unfold over time, necessitating longitudinal research designs. Longitudinal research poses a host of methodological challenges, foremost of which is participant attrition. Building on Dillman's work, we provide a review of how social influence and relationship research informs retention strategies in longitudinal studies. Objective: We introduce the tailored panel management (TPM) approach, which is designed to establish communal norms that increase commitment to a longitudinal study, and this commitment, in turn, increases response rates and buffers against attrition. Specifically, we discuss practices regarding compensation, communication, consistency, and credibility that increase longer term commitment to panel participation. Research design: Throughout the article, we describe how TPM is being used in a national longitudinal study of undergraduate minority science students. TheScienceStudy is a continuing panel, which has 12 waves of data collected across 6 academic years, with response rates ranging from 70% to 92%. Although more than 90% of participants have either left or graduated from their undergraduate degree program, this highly mobile group of people remains engaged in the study. TheScienceStudy has usable longitudinal data from 96% of the original panel. Conclusion: This article combines social psychological theory, current best practice, and a detailed case study to illustrate the TPM approach to longitudinal data collection. The approach provides guidance for other longitudinal researchers, and advocates for empirical research into longitudinal research methodologies. © The Author(s) 2014.

Clinical-scale expansion of CD34+ cord blood cells amplifies committed progenitors and rapid scid repopulation cells.

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.

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

PubMed Central

Reid, Gary; Sharma, Mukta; Higgs, Peter

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.

Introduction Presence of committed personnel in each organization not only reduces their absenteeism, delays, and displacements but also leads to a dramatic increase in performance and efficiency of an organization, mental freshness of employees, better manifestation of noble objectives, and organizational mission as well as fulfillment of personal goals. Therefore, the purpose of this study was to determine the relationship between organizational culture and organizational commitment of employees in administrative units of health care centers in the cities of Hamedan Province based on the Denison model in 2015. Methods In this cross-sectional study, 177 employees in administrative units of health care centers in the cities of Hamedan Province were selected by a multistage stratified sampling method. The data collection instruments included the standardized Denison organizational culture survey and organizational commitment questionnaire by Meyer and Allen. Data were analyzed by IBM-SPSS version 21 using descriptive statistics and Pearson product-moment coefficient. Results Among the 12 indicators of organizational culture, the highest mean scores were assigned to empowerment (16.74), organizational learning (16.41), vision (16.4), and strategic direction (16.35); respectively. Furthermore, the indicators of capability development (14.2), core values (15.31), team orientation (15.45), and goals (15.46) received the lowest mean scores in this respect. Among the four dimensions of organizational culture, the highest mean score was related to “mission” in organizational culture and the lowest score was associated with “involvement.” Meyer and Allen’s organizational commitment model also had three components in which affective commitment in this study obtained the highest score (26.63) and continuance commitment received the lowest score (24.73). In this study, there was a significant correlation between all the components of organizational culture and organizational commitment of employees in administrative units of health care centers (p < 0.05). Conclusion Reflecting on all the dimensions and indicators of organizational culture can lead to an escalation of organizational commitment among employees. Furthermore, focus on factors affecting the improvement of continuance commitment can promote organizational commitment of employees in administrative units of health care centers. PMID:28243419

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.

Professional commitment is defined as a belief in and acceptance of the values of the profession which is chosen, effort to actualize these values, desire to improve him/herself. Nurses' professional and organizational commitment are influenced by factors such as job stress, job satisfaction and burnout. This study was conducted to determine the effect of nursing internship program on professional commitment and burnout of senior nursing students. A quasi-experimental study with a pretest and posttest without control group design was used. Students who were attending nursing internship program and agreed to participate were included in the study. Sample consisted of 101 students. Data were collected with a questionnaire, the burnout measure short version and nursing professional commitment scale. After the nursing internship, 77.2% were pleased to study nursing, 83.2% were pleased to be a senior student, 55.4% did not have any intention to change their profession, 81.2% wanted to work as nurses, and 82.2% were planning career advancement in nursing of the students, 34.7% and 43.6% were found to experience burnout, before and after the nursing internship, respectively (p < 0.05). When the students' mean pre-test and post-test scores on the nursing professional commitment scale were compared, a significant difference was found between mean scores on the total score and "maintaining membership" subscale (p < 0.05). This study revealed that after the nursing internship, burnout and professional commitment levels of the students increased. Copyright © 2018 Elsevier Ltd. All rights reserved.

Motivated and committed employees deliver better health care, which results in better outcomes and higher patient satisfaction. To assess the Organizational Commitment and Intrinsic Motivation of Primary Health Care Providers (HCPs) in New Delhi, India. Study was conducted in 2013 on a sample of 333 HCPs who were selected using multistage stage random sampling technique. The sample includes medical officers, auxiliary nurses and midwives, and pharmacists and laboratory technicians/assistants among regular and contractual staff. Data were collected using the pretested structured questionnaire for organization commitment (OC), job satisfiers, and intrinsic job motivation. Analysis was done by using SPSS version 18 and appropriate statistical tests were applied. The mean score for OC for entire regular staff is 1.6 ± 0.39 and contractual staff is 1.3 ± 0.45 which has statistically significant difference (t = 5.57; P = 0.00). In both regular and contractual staff, none of them show high emotional attachment with the organization and does not feel part of the family in the organization. Contractual staff does not feel proud to work in a present organization for rest of their career. Intrinsic motivation is high in both regular and contractual groups but intergroup difference is significant (t = 2.38; P < 0.05). Contractual staff has more dissatisfier than regular, and the difference is significant (P < 0.01). Organizational commitment and intrinsic motivation of contractual staff are lesser than the permanent staff. Appropriate changes are required in the predictors of organizational commitment and factors responsible for satisfaction in the organization to keep the contractual human resource motivated and committed to the organization.

INTRODUCTION: Electronic medical record system (EMRS) is a valuable system for safe access to the patient's data and increases health care quality. Manpower is one of the requirements for EMRS, among which manager is the most important person in any hospital. Taking into account manager's positive attitude and good commitments, EMRS will be implemented successfully. As such, we decided to assess manager's attitude and commitment toward EMRS in Isfahan hospitals in the year of 2014. AIM: This article aimed to determine the hospital managers’ attitude and commitment toward the implementation of EMRS. MATERIALS AND METHODS: The present article is an applied analytic study. Research society consisted of the managers of all the hospitals in Isfahan that include hospitals affiliated to Isfahan University of Medical Sciences, private, and social security hospitals. This study was done in 2014. Data collection tools included a questionnaire for which reliability and validity were determined. Data were analyzed by means of SPSS 20. RESULTS: Average score for the managers’ attitude toward EMRS in the city of Isfahan was 77.5 out of 100 and their average score for commitment was 74.7. Manager's attitude in social security hospitals was more positive than the private and governmental ones (83.3%). In addition, the amount of commitment by the managers in social security hospitals was higher than the same in private and governmental hospitals (86.6%). CONCLUSION: At present, managers’ attitude and commitment in Isfahan hospitals toward EMRS are very high and social security hospitals show more readiness in this respect. PMID:28584837

The EU pledge for responsible marketing of food and beverages to children: implementation in food companies.

PubMed

Jensen, J D; Ronit, K

2015-08-01

Increasing political pressure on the food industry's marketing activities stimulated the formation of the collective EU Pledge for responsible marketing of foods and beverages to children. The objective of the study is to evaluate the commitments made by companies in joining the pledge for the purpose of assessing its effectiveness in regulating signatory companies' marketing activities. Data on company commitments in relation to the EU Pledge were collected, analyzed and recalculated in order to enable comparison across companies and with general nutritional recommendations. Data on companies' product portfolio and market orientation were collected from their most recent available annual reports. Data on the companies' product profiles were generated via review of the companies' main websites. Similar data were generated for a reference group of companies outside the EU Pledge. Compared with a reference group of large food and beverage companies, EU Pledge signatory companies have a public image strongly based on products with appeal to children. The EU Pledge sets common standards for regulating signatory companies' marketing behaviour towards children. Further scrutiny of the companies' stated commitments revealed considerable variation in their actual content and in their de facto bindingness on the companies' marketing behavior--for example, in the definition of target audience for advertising or in nutritional characteristics making products eligible for advertising to children. In order for voluntary self-regulation schemes such as the EU Pledge to be a credible alternative to public regulation of marketing behaviour, more transparency and stringency are needed.

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.

The transference of radionuclides from the fertilizers to/and from soils to the foodstuffs can represent an increment in the internal dose when the vegetables are consumed by the human beings. This work evaluates the contribution of fertilizers to the increase of radiation level in the environment and of dose to the people. Samples of fertilizers, soils and vegetables produced in farms located in the neighbourhood of Sao Paulo city in the State of Sao Paulo, Brazil were analysed through gamma spectroscopy. The values of specific activity of {sup 40}K, {sup 238}U and {sup 232}Th show that there is no significantmore » transference of natural radionuclides from fertilizers to the final product of the food chain. The annual committed effective dose due to the ingestion of {sup 40}K contained in the group of consumed vegetables analysed in this work resulted in the very low value of 0.882 {mu}Sv.« less

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

Weafer, Jessica; Fillmore, Mark T.

2012-01-01

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.

Environmental analysis burial of offsite low-level waste at SRP

1980-12-01

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.

Working conditions in call/contact centers influence employees' perceptions of their relations with the organization and their attitudes to work. Such perceptions can be analyzed through the psychological contract. The association between the relational/transactional orientation of the psychological contract and intention to quit the organization was examined, as well as the mediating role of affective commitment in employment relations. Data were collected from 973 employees in a cross-sectional survey. Analysis confirmed that there was a statistically significant relation between the orientation of the psychological contract and intention to quit, which was positive for transactionally oriented and negative for relationally oriented contracts. A mediating role for affective commitment was also confirmed, and a full mediating effect was reported for both orientations.

Dose Calculation For Accidental Release Of Radioactive Cloud Passing Over Jeddah

NASA Astrophysics Data System (ADS)

Alharbi, N. D.; Mayhoub, A. B.

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.

Preserving the national blood supply.

Brittenham, G M; Klein, H G; Kushner, J P; Ajioka, R S

2001-01-01

This paper examines the current state of the blood supply in the US and focuses on the potential for augmenting blood availability by attention to the iron status of donors. Increasing demands are being made upon the national blood supply as rates of blood donation are declining, in part because of the loss of blood donors as a result of enhanced screening and testing procedures. Iron-related means of expanding the blood supply include the use of blood from individuals undergoing therapeutic phlebotomy for hereditary hemochromatosis and enhancing the retention and commitment of women of childbearing age as donors by using iron supplementation to prevent iron deficiency. In Section I, Dr. Klein discuss the circumstances responsible for a decline in the population of eligible donors, including public attitudes toward donation, factors influencing the retention of donors by blood centers, and the effects of increased screening and testing to maintain the safety of the blood supply. In Section II, Drs. Kushner and Ajioka focus on the consequences of the decision by the US Food and Drug Administration (FDA) to develop recommendations to permit blood centers to collect blood from patients with hereditary hemochromatosis and to distribute this blood obtained without disease labeling if all other screening and testing procedures are passed. After summarizing the pathophysiology of hereditary hemochromatosis, the use by blood centers of blood obtained from heterozygotes and homozygotes for hereditary hemochromatosis is considered. In Section III, Dr. Brittenham reviews the use of low dose, short-term carbonyl iron supplementation for women donors of childbearing age. Replacing the iron lost at donation can help prevent iron deficiency in women of childbearing age and, by decreasing deferral, enhance the retention and commitment of women who give blood regularly. He emphasizes the use by blood centers of iron-related means to enhance recruitment and retention of blood donors.

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. The reader will be able to: (a) appreciate the potential for Acceptance and Commitment Therapy for adults who stutter; (b) identify the improvements participants experienced in psychosocial functioning and frequency of stuttered speech; (c) appreciate the six core processes of Acceptance and Commitment Therapy; and (d) appreciate the differences between an ACT model of intervention for adults who stutter compared to a CBT approach.

To explore Jordanian chronic illnesses patients' perceived exercise self-efficacy, benefits and barriers, and commitment to exercise planning, and to assess the relationship between those variables. Descriptive cross-sectional design. Data were collected from a convenience sample of 402 outpatient Jordanians with chronic illnesses, using Exercise Self-Efficacy Scale, Exercise Benefits and Barriers Scale, and Commitment to a Plan for Exercise Scale. The average BMI was 28.3, and exercise period 3.2 hours/ week. Participants reported moderate perceived self-efficacy (M= 47.5%, SD= 11.7), commitment to exercise planning (M=2.0/3, SD=0.3), exercise barriers (M=2.4/4, SD=0.3), and benefits (M=2.3/4, SD=0.3). Commitment to exercise planning had a significant correlation with barriers (r=0.11) and benefits (r=0.10). Self-efficacy was not found to correlate with other variables. Even though participants reported higher perceived self-efficacy and commitment to exercise plan than that reported in literature, they were found to be overweight and inactive, which indicates the importance of such study. Exercise education programs are needed taking into considerations patients' individual differences. However, the broad grouping of diseases may not produce a homogenous sample, for which disease categories are recommended in future studies. Patients with chronic illness need more encouragement to engage themselves in exercise practices. Exercise educational program for patients with chronic illnesses should consider patients' reported exercise benefits and barriers. © 2014 Association of Rehabilitation Nurses.

Incomplete radiation exposure histories, inadequate treatment of internally deposited radionuclides, and failure to account for neutron exposures can be important uncertainties in epidemiologic studies of radiation workers. Organ-specific doses from lifetime occupational exposures and radionuclide intakes were estimated for an epidemiologic study of 5,801 Rocketdyne/Atomics International (AI) radiation workers engaged in nuclear technologies between 1948 and 1999. The entire workforce of 46,970 Rocketdyne/AI employees was identified from 35,042 Kardex work histories cards, 26,136 electronic personnel listings, and 14,189 radiation folders containing individual exposure histories. To obtain prior and subsequent occupational exposure information, the roster of all workers was matched against nationwide dosimetry files from the Department of Energy, the Nuclear Regulatory Commission, the Landauer dosimetry company, the U.S. Army, and the U.S. Air Force. Dosimetry files of other worker studies were also accessed. Computation of organ doses from radionuclide intakes was complicated by the diversity of bioassay data collected over a 40-y period (urine and fecal samples, lung counts, whole-body counts, nasal smears, and wound and incident reports) and the variety of radionuclides with documented intake including isotopes of uranium, plutonium, americium, calcium, cesium, cerium, zirconium, thorium, polonium, promethium, iodine, zinc, strontium, and hydrogen (tritium). Over 30,000 individual bioassay measurements, recorded on 11 different bioassay forms, were abstracted. The bioassay data were evaluated using ICRP biokinetic models recommended in current or upcoming ICRP documents (modified for one inhaled material to reflect site-specific information) to estimate annual doses for 16 organs or tissues taking into account time of exposure, type of radionuclide, and excretion patterns. Detailed internal exposure scenarios were developed and annual internal doses were derived on a case-by-case basis for workers with committed equivalent doses indicated by screening criteria to be greater than 10 mSv to the organ with the highest internal dose. Overall, 5,801 workers were monitored for radiation at Rocketdyne/AI: 5,743 for external exposure and 2,232 for internal intakes of radionuclides; 41,169 workers were not monitored for radiation. The mean cumulative external dose based on Rocketdyne/AI records alone was 10.0 mSv, and the dose distribution was highly skewed with most workers experiencing low cumulative doses and only a few with high doses (maximum 500 mSv). Only 45 workers received greater than 200 mSv while employed at Rocketdyne/AI. However, nearly 32% (or 1,833) of the Rocketdyne/AI workers had been monitored for radiation at other nuclear facilities and incorporation of these doses increased the mean dose to 13.5 mSv (maximum 1,005 mSv) and the number of workers with >200 mSv to 69. For a small number of workers (n=292), lung doses from internal radionuclide intakes were relatively high (mean 106 mSv; maximum 3,560 mSv) and increased the overall population mean dose to 19.0 mSv and the number of workers with lung dose>200 mSv to 109. Nearly 10% of the radiation workers (584) were monitored for neutron exposures (mean 1.2 mSv) at Rocketdyne/AI, and another 2% were monitored for neutron exposures elsewhere. Interestingly, 1,477 workers not monitored for radiation at Rocketdyne/AI (3.6%) were found to have worn dosimeters at other nuclear facilities (mean external dose of 2.6 mSv, maximum 188 mSv). Without considering all sources of occupational exposure, an incorrect characterization of worker exposure would have occurred with the potential to bias epidemiologic results. For these pioneering workers in the nuclear industry, 26.5% of their total occupational dose (collective dose) was received at other facilities both prior to and after employment at Rocketdyne/AI. In addition, a small number of workers monitored for internal radionuclides contributed disproportionately to the number of workers with high lung doses. Although nearly 12% of radiation workers had been monitored for neutron exposures during their career, the cumulative dose levels were small in comparison with other external and internal exposure. Risk estimates based on nuclear worker data must be interpreted cautiously if internally deposited radionuclides and occupational doses received elsewhere are not considered.

SU-C-201-03: Ionization Chamber Collection Efficiency in Pulsed Radiation Fields of High Pulse Dose

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

Gotz, M; Karsch, L; Pawelke, J

Purpose: To investigate the reduction of collection efficiency of ionization chambers (IC) by volume recombination and its correction in pulsed fields of very high pulse dose. Methods: Measurements of the collection efficiency of a plane-parallel advanced Markus IC (PTW 34045, 1mm electrode spacing, 300V nominal voltage) were obtained for collection voltages of 100V and 300V by irradiation with a pulsed electron beam (20MeV) of varied pulse dose up to approximately 600mGy (0.8nC liberated charge). A reference measurement was performed with a Faraday cup behind the chamber. It was calibrated for the liberated charge in the IC by a linear fitmore » of IC measurement to reference measurement at low pulse doses. The results were compared to the commonly used two voltage approximation (TVA) and to established theories for volume recombination, with and without considering a fraction of free electrons. In addition, an equation system describing the charge transport and reactions in the chamber was solved numerically. Results: At 100V collection voltage and moderate pulse doses the established theories accurately predict the observed collection efficiency, but at extreme pulse doses a fraction of free electrons needs to be considered. At 300V the observed collection efficiency deviates distinctly from that predicted by any of the established theories, even at low pulse doses. However, the numeric solution of the equation system is able to reproduce the measured collection efficiency across the entire dose range of both voltages with a single set of parameters. Conclusion: At high electric fields (3000V/cm here) the existing theoretical descriptions of collection efficiency, including the TVA, are inadequate to predict pulse dose dependency. Even at low pulse doses they might underestimate collection efficiency. The presented, more accurate numeric solution, which considers additional effects like electric shielding by the charges, might provide a valuable tool for future investigations.

Background: High turnover intention rate is one of the most common problems in healthcare organizations throughout the world. There are several factors that can potentially affect the individuals’ turnover intention; they include factors such as work-family conflict, family-work conflict, and organizational commitment. The aim of this research was to determine the relationship between family-work and work-family conflicts and organizational commitment and turnover intention among nurses and paramedical staff at hospitals affiliated to Shiraz University of Medical Sciences (SUMS) and present a model using SEM. Methods: This is a questionnaire based cross-sectional study among 400 nurses and paramedical staff of hospitals affiliated to SUMS using a random-proportional (quota) sampling method. Data collection was performed using four standard questionnaires. SPSS software was used for data analysis and SmartPLS software for modeling variables. Results: Mean scores of work-family conflict and desertion intention were 2.6 and 2.77, respectively. There was a significant relationship between gender and family-work conflict (P=0.02). Family-work conflict was significantly higher in married participants (P=0.001). Based on the findings of this study, there was a significant positive relationship between work-family and family-work conflict (P=0.001). Also, work-family conflict had a significant inverse relationship with organizational commitment (P=0.001). An inverse relationship was seen between organizational commitment and turnover intentions (P=0.001). Conclusion: Thus, regarding the prominent and preventative role of organizational commitment in employees’ desertion intentions, in order to prevent negative effects of staff desertion in health sector, attempts to make policies to increase people’s organizational commitment must be considered by health system managers more than ever.

Background: Motivated and committed employees deliver better health care, which results in better outcomes and higher patient satisfaction. Objective: To assess the Organizational Commitment and Intrinsic Motivation of Primary Health Care Providers (HCPs) in New Delhi, India. Materials and Methods: Study was conducted in 2013 on a sample of 333 HCPs who were selected using multistage stage random sampling technique. The sample includes medical officers, auxiliary nurses and midwives, and pharmacists and laboratory technicians/assistants among regular and contractual staff. Data were collected using the pretested structured questionnaire for organization commitment (OC), job satisfiers, and intrinsic job motivation. Analysis was done by using SPSS version 18 and appropriate statistical tests were applied. Results: The mean score for OC for entire regular staff is 1.6 ± 0.39 and contractual staff is 1.3 ± 0.45 which has statistically significant difference (t = 5.57; P = 0.00). In both regular and contractual staff, none of them show high emotional attachment with the organization and does not feel part of the family in the organization. Contractual staff does not feel proud to work in a present organization for rest of their career. Intrinsic motivation is high in both regular and contractual groups but intergroup difference is significant (t = 2.38; P < 0.05). Contractual staff has more dissatisfier than regular, and the difference is significant (P < 0.01). Conclusion: Organizational commitment and intrinsic motivation of contractual staff are lesser than the permanent staff. Appropriate changes are required in the predictors of organizational commitment and factors responsible for satisfaction in the organization to keep the contractual human resource motivated and committed to the organization.

An inverse relationship was seen between organizational commitment and turnover intentions (P=0.001). Thus, regarding the prominent and preventative role of organizational commitment in employees' desertion intentions, in order to prevent negative effects of staff desertion in health sector, attempts to make policies to increase people's organizational commitment must be considered by health system managers more than ever.

Healthcare organizations are now challenged to retain nurses' generation and understand why they are leaving their nursing career prematurely. Acquiring knowledge about the effect of ethical work climate and level of perceived organizational support can help organizational leaders to deal effectively with dysfunctional behaviors and make a difference in enhancing nurses' dedication, commitment, satisfaction, and loyalty to their organization. This study aims to determine the relationship between ethical work climate, and perceived organizational support and nurses' organizational commitment, job satisfaction, and turnover intention. A descriptive correlational research design was conducted in all inpatient care units at three major hospitals affiliated to different health sectors at Alexandria governorate. All nurses working in these previous hospitals were included in the study (N = 500). Ethical Climate Questionnaire, Survey of Perceived Organizational Support, Organizational Commitment Questionnaire, Index of Job Satisfaction, and Intention to Turnover scale were used to measure study variables. Ethical considerations: Approval was obtained from Ethics Committee at Faculty of Nursing, Alexandria University. Privacy and confidentiality of data were maintained and assured by obtaining subjects' informed consent to participate in the research before data collection. The result revealed positive significant correlations between nurses' perception of overall ethical work climate and each of perceived organizational support, commitment, as well as their job satisfaction. However, negative significant correlations were found between nurses' turnover intention and each of these variables. Also, approximately 33% of the explained variance of turnover intention is accounted by ethical work climate, organizational support, organizational commitment, and job satisfaction, and these variables independently contributed significantly in the prediction of turnover intention. Strategies to foster and enhance ethical and supportive work climates as well as job-related benefits are considered significant factors in increasing nurses' commitment and satisfaction and decreasing their turnover intention.

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.

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

Pessach, I; Resnick, I; Shimoni, A; Nagler, A

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.

Malaysian construction sector is regarded as critical in the field of health because of the high rates of accidents and fatalities. This research aimed to determine the prevalence, sources and severity of injuries and its association with commitment to safety among foreign construction workers. A cross-sectional study was conducted among 323 foreign construction workers from six construction projects of a large organization in Malaysia, using a simple random sampling method. Data was collected using a structured questionnaire to assess work-related injuries and safety commitment. The collected data was analysed by SPSS 22.0 using descriptive statistics and χ 2 test. The prevalence of work-related injuries in a one year period was 22.6%, where most of the injuries were of moderate severity (39.7%) and falls from heights represented the main source (31.5%). The majority of the foreign construction workers had perceived between moderate and high safety commitment, which was significantly associated with work-related injuries. The results also showed a significant association of work-related injuries with the company's interest in Safety and Health, Safety and Health training, and safety equipment. Thus, the implementation of new procedures and providing relevant trainings and safety equipment; will lead to a decrease in injury rates in construction sites.

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

Measurement of the concentration of radon gas in the Toirano's caves (Liguria).

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.

Developmental Climate: A Cross-level Analysis of Voluntary Turnover and Job Performance

2014-01-01

This research investigates the influence of shared perceptions of developmental climate on individual-level perceptions of organizational commitment, engagement, and perceived competence, and whether these attitudes mediate the relationship between developmental climate and both individual voluntary turnover and supervisor-rated job performance. Survey data were collected from 361 intact employee-supervisory mentoring dyads and matched with employee turnover data collected one year later to test the proposed framework using multilevel modeling techniques. As expected, shared perceptions of developmental climate were significantly and positively related to all three individual work attitudes. In addition, both organizational commitment and perceived competence were significant mediators of the positive relationship between shared perceptions of developmental climate and voluntary turnover, as well as shared perceptions of developmental climate and supervisor-rated job performance. By contrast, no significant mediating effects were found for engagement. Theoretical implications, limitations, and future research are discussed. PMID:24748681

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.

One of the dominant tree species growing within and around Los Alamos National Laboratory (LANL), Los Alamos, NM, lands is the pinon pine (Pinus edulis) tree. Pinon pine is used for firewood, fence posts, and building materials and is a source of nuts for food--the seeds are consumed by a wide variety of animals and are also gathered by people in the area and eaten raw or roasted. This study investigated the (1) concentration of {sup 3}H, {sup 137}Cs, {sup 90}Sr, {sup tot}U, {sup 238}Pu, {sup 239,240}Pu, and {sup 241}Am in soils (0- to 12-in. [31 cm] depth underneath themore » tree), pinon pine shoots (PPS), and pinon pine nuts (PPN) collected from LANL lands and regional background (BG) locations, (2) concentrations of radionuclides in PPN collected in 1977 to present data, (3) committed effective dose equivalent (CEDE) from the ingestion of nuts, and (4) soil to PPS to PPN concentration ratios (CRs). Most radionuclides, with the exception of {sup 3}H in soils, were not significantly higher (p < 0.10) in soils, PPS, and PPN collected from LANL as compared to BG locations, and concentrations of most radionuclides in PPN from LANL have decreased over time. The maximum net CEDE (the CEDE plus two sigma minus BG) at the most conservative ingestion rate (10 lb [4.5 kg]) was 0.0018 mrem (0.018 {micro}Sv). Soil-to-nut CRs for most radionuclides were within the range of default values in the literature for common fruits and vegetables.« less

The relationship between South Korean clinical nurses' attitudes toward organizations and voluntary turnover intention: A path analysis.

Kim, Jong Kyung; Chang, Sun Ju

2015-08-01

The purpose of this study was to examine the relationship between attitudes toward their organizations and voluntary turnover intention among South Korean clinical nurses. Data from a total of 312 clinical nurses in six hospitals in South Korea were collected for the study. Both hierarchical multiple regression analysis and path analysis were used to analyse the data. The overall fit of the hypothetical model was good. Voluntary turnover intention was found to have significant direct pathways to job embeddedness and organizational commitment. Organizational commitment and satisfaction with organizational rewards had indirect pathways to voluntary turnover intention through job embeddedness. All variances explained 62.3% of the voluntary turnover intention scores. The findings suggest that greater job embeddedness, organizational commitment and satisfaction with organizational rewards lead to lower voluntary turnover intention among clinical nurses in South Korea. © 2014 Wiley Publishing Asia Pty Ltd.

Enhancement of Structured Reporting - an Integration Reporting Module with Radiation Dose Collection Supporting.

PubMed

Lee, Ming-Che; Chuang, Kei-Shih; Hsu, Tien-Cheng; Lee, Chien-Ding

2016-11-01

Collection of radiation dose derived from radiological examination is necessary not only for radiation protection, but also for fulfillment of structured reports. However, the material regarding of radiation dose cannot be directly utilized by the Radiological Information System (RIS) since it is generated and only stored in the Picture Archiving and Communication System (PACS). In this paper, an integration reporting module is proposed to facilitate handling of dose information and structured reporting by providing two functionalities. First, a gateway is established to automatically collect the related information from PACS for further analyzing and monitoring the accumulated radiation. Second, the designated structured reporting patterns with corresponding radiation dose measurements can be acquired by radiologists as necessary. In the design, the radiation dose collection gateway and the well-established pattern are collocated to achieve that there is no need to do manual entry for structured reporting, thus increasing productivity and medical quality.

Method to determine the position-dependant metal correction factor for dose-rate equivalent laser testing of semiconductor devices

DOEpatents

Horn, Kevin M.

2013-07-09

A method reconstructs the charge collection from regions beneath opaque metallization of a semiconductor device, as determined from focused laser charge collection response images, and thereby derives a dose-rate dependent correction factor for subsequent broad-area, dose-rate equivalent, laser measurements. The position- and dose-rate dependencies of the charge-collection magnitude of the device are determined empirically and can be combined with a digital reconstruction methodology to derive an accurate metal-correction factor that permits subsequent absolute dose-rate response measurements to be derived from laser measurements alone. Broad-area laser dose-rate testing can thereby be used to accurately determine the peak transient current, dose-rate response of semiconductor devices to penetrating electron, gamma- and x-ray irradiation.

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.

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

From controlled to committed.

Hess, J C

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.

Many studies have found management commitment to safety to be an important construct of safety climate. This study examined the association between supervisor and employee (shared and individual) perceptions of management commitment to safety and the rate of future injuries in limited-service restaurant workers. A total of 453 participants (34 supervisors/managers and 419 employees) from 34 limited-service restaurants participated in a prospective cohort study. Employees' and managers' perceptions of management commitment to safety and demographic variables were collected at the baseline. The survey questions were made available in three languages: English, Spanish, and Portuguese. For the following 12 weeks, participants reported their injury experience and weekly work hours. A multivariate negative binomial generalized estimating equation model with compound symmetry covariance structure was used to assess the association between the rate of self-reported injuries and measures of safety perceptions. There were no significant relationships between supervisor and either individual or shared employee perceptions of management commitment to safety. Only individual employee perceptions were significantly associated with future employee injury experience but not supervisor safety perceptions or shared employee perceptions. Individual employee perception of management commitment to safety is a significant predictor for future injuries in restaurant environments. A study focusing on employee perceptions would be more predictive of injury outcomes than supervisor/manager perceptions. Copyright © 2012 Elsevier Ltd. All rights reserved.

Commit* to change? A call to end the publication of the phrase ‘commit* suicide’

Nielsen, Emma; Padmanathan, Prianka; Knipe, Duleeka

2016-01-01

Background. Countering stigma is a fundamental facet of suicide prevention efforts.  Integral to this is the promotion of accurate and sensitive language.  The phrase ‘commit* suicide’ has prompted marked opposition primarily due to the connotations of immorality and illegality.  Methods. The study investigated the frequency of the use of the wordstem ‘commit’, in relation to self-harm and suicidal behaviours, in the three leading suicide-specific academic journals between 2000 and 2015.  Results. One third (34%) of articles published since the year 2000 used the word ‘commit*’ when describing an act of self-harm or suicide. Over half of these articles (57%) used the phrase on more than one occasion, with 6% using it more than 10 times in the same manuscript. The percentage of papers utilising the word ‘commit*’ has fluctuated over time, but there is a promising downward trend in the use of this phrase from 33% in 2000 to 13% in 2015 ( p < 0.001).  Discussion. We advocate for the implementation of publication requirements regarding the language used when discussing suicide. Whilst we call for collective responsibility amongst academics and clinicians, editors hold a unique position in ensuring that outdated, inaccurate and stigma-laden terms are expunged from the scientific literature.

GUTIERAIM: The aim of this correlational study was to examine the relations between organizational commitment, perceived organizational support, work values, person-organization fit, developmental experiences, and global job satisfaction among nursing faculty. The global nursing shortage is well documented. At least 57 countries have reported critical shortages. The lack of faculty is finally being recognized as a major issue directly influencing the ability to admit and graduate adequate numbers of nurses. As efforts increase to both recruit and retain faculty, the concept of organizational commitment and what it means to them is important to consider. A cross-sectional correlational design was used. The present study investigated the underlying structure of various organizational factors using structural equation modelling. Data were collected from a stratified random sample of nurse faculty during the academic year 2006-2007. The final model demonstrated that perceived organizational support, developmental experiences, person-organization fit, and global job satisfaction positively predicted nurse faculty's organizational commitment to the academic organization. Cross-validation results indicated that the final full SEM is valid and reliable. Nursing faculty administrators able to use mentoring skills are well equipped to build positive relationships with nursing faculty, which in turn, can lead to increased organizational commitment, productivity, job satisfaction, and perceived organizational support, among others. © 2012 Blackwell Publishing Ltd.

Career Commitment of Postprofessional Athletic Training Program Graduates

2015-01-01

Context: Choosing to pursue an advanced degree in athletic training appears to indicate professional commitment and passion for the profession. Currently, there is a paucity of information regarding why some athletic trainers pursue enrollment in a postprofessional athletic training program (PPATP), indicating commitment to the profession, but later depart for another primary role outside of athletic training. Objective: To understand why athletic trainers invested in advanced training via a PPATP but then decided to leave the profession. Design: Qualitative study. Setting: Online data collection. Patients or Other Participants: Twelve graduates (8 women [67%], 4 men [33%], age = 31.58 ± 3.06 years) from PPATPs who no longer had primary employment as an athletic trainer. Data Collection and Analysis: Recruits responded to an e-mail invitation to participate by completing a confidential online questionnaire. We analyzed data using a general inductive approach and secured trustworthiness using multiple-analyst triangulation, peer review, and member checks. Results: Two higher-order themes emerged regarding the career commitment of former athletic trainers who were PPATP graduates: (1) departure from an athletic training career and (2) partial continuance in athletic training. Two second-order themes emerged from the reasons for departure: (1) decreased recognition of value and (2) work-life imbalance. Finally, we identified 2 third-order themes from the participants' reasons for departure because of a perceived lack of value: (1) low salary and (2) long, inconsistent hours worked. Conclusions: Most of our participants intended to stay in the profession when they chose to attend a PPATP. However, during role inductance in either the clinical experience of the PPATP they attended or early in their careers, they began to have thoughts of leaving mainly because of inadequate financial compensation, challenging work schedules, or both.

To report a study of the relationship between variables at the group and individual level with nurses' intention to leave their unit. Workplaces are collective environments where workers constantly interact with each other. The quality of working relationship employees develop at the unit-level influences both employee outcomes and unit performance by shaping employee attitudes. The study was a cross-sectional design with self-administered questionnaires. A questionnaire including measures of leader-member exchange and nurse-physician collaboration analysed at group-level and affective commitment and turnover intention analysed at individual level, was administered individually to 1018 nurses in five Italian hospitals. Data were collected in 2009. A total of 832 nurses (81·7% response rate) completed questionnaires. The results showed that affective commitment at individual level completely mediated the relationship between leader-member exchange at group-level and nursing turnover intention. Furthermore, the cross-level interaction was significant: at individual level, the nurses with high levels of individual affective commitment towards their unit showed low levels of turnover intention and this relationship was stronger when the nurse-physician collaboration at group-level was high. This study showed the importance for organizations to implement management practices that promote both high-quality nurse-supervisor and nurse-physician relationships, because they increase nurses' identification with their units. Individual affective commitment is an important quality for retaining a workforce and good nurses' relationship at group-level relationships with both supervisors and physicians are instrumental in developing identification with the work unit. Thus, the quality of relationship among staff members is an important factor in nurses' decision to leave. © 2012 Blackwell Publishing Ltd.

2016-05-01

The number of computed tomography examinations has continuously increased over the last decades and accounts for a major part of the collective radiation dose from medical investigations. For purposes of quality assurance in modern radiology a systematic monitoring and analysis of dose related data from radiological examinations is mandatory. Various ways of collecting dose data are available today, for example the Digital Imaging and Communication in Medicine - Structured Report (DICOM-SR), optical character recognition and DICOM-modality performed procedure steps (MPPS). The DICOM-SR is part of the DICOM-standard and provides the DICOM-Radiation Dose Structured Report, which is an easily applicable and comprehensive solution to collect radiation dose parameters. This standard simplifies the process of data collection and enables comprehensive dose monitoring. Various commercial dose monitoring software devices with varying characteristics are available today. In this article, we discuss legal obligations, various ways to monitor dose data, current dose monitoring software solutions and future perspectives in regard to the EU Council Directive 2013/59/EURATOM. • Automated, systematic dose monitoring is an important element in quality assurance of radiology departments. • DICOM-RDSR-capable CT scanners facilitate the monitoring of dose data. • A variety of commercial and non-commercial dose monitoring software tools are available today. • Successful dose monitoring requires comprehensive infrastructure for monitoring, analysing and optimizing radiation exposure.

Comparison of alcohol impairment of behavioral and attentional inhibition.

PubMed

Weafer, Jessica; Fillmore, Mark T

2012-11-01

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.

Because of the nursing shortage problem, an important goal for nurse managers is preventing nurses from leaving the organization. This study analyzed the effect of evidence-based nursing management practices on nurses' levels of job satisfaction, organizational commitment, and intent to leave using the Promoting Action Research Implementation in Health Service framework as a guide. This study employed a single-group, quasi-experimental, pretest-post-test design with repeated measures. Data were collected using the Minnesota Job Satisfaction Questionnaire and the Organizational Commitment Scale. The study was conducted at a 127-bed private, accredited hospital. The sample was composed of 58 nurses who participated in all three measurements. Data analysis was conducted using repeated-measures anova and the Cochrane Q-test. An improvement was observed in the nurses' intrinsic, extrinsic, and total satisfaction levels, and in the degree of normative commitment. Nurse managers stated that they benefited from this study. In order to find effective and long-lasting solutions to the nursing shortage problem, evidence-based recommendations should be used in nursing management. © 2012 Blackwell Publishing Asia Pty Ltd.

To examine the relationships between leader-member exchange (LMX), workplace learning options (teamwork, training and development), empowerment and organisational commitment, for nurses in Australia, England and Brazil. The supervisor-employee relationship is fundamental to management theory and practice within the work context of Organisation for Economic Cooperation and Development (OECD) countries. Survey-based, self-report data were collected from 1350 nurses in 23 acute-care hospitals during 2011. Significant relationships were found between key Social Exchange Theory antecedents (LMX and teamwork) and outcomes (organisational commitment) for nurses in Australia and England, but not in Brazil. As expected, the path between teamwork and organisational commitment was significant in the three countries. The findings affirm the importance of LMX as a management tool affecting employee outcomes in OECD countries. In contrast, LMX cannot be assumed to play an important role within a context that operates a dual employment structure coupled with a culture accepting of 'Jeitinho' workplace relationships. Informal workplace relationships - 'Jeitinho' (similar to the Chinese 'guanxi') may be worthy of examination within BRICS (Brazil, Russia, India, China and South Africa) countries such as Brazil. © 2014 John Wiley & Sons Ltd.

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.

2018-03-01

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.

SU-F-P-19: Fetal Dose Estimate for a High-Dose Fluoroscopy Guided Intervention Using Modern Data Tools

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

Moirano, J

Purpose: An accurate dose estimate is necessary for effective patient management after a fetal exposure. In the case of a high-dose exposure, it is critical to use all resources available in order to make the most accurate assessment of the fetal dose. This work will demonstrate a methodology for accurate fetal dose estimation using tools that have recently become available in many clinics, and show examples of best practices for collecting data and performing the fetal dose calculation. Methods: A fetal dose estimate calculation was performed using modern data collection tools to determine parameters for the calculation. The reference pointmore » air kerma as displayed by the fluoroscopic system was checked for accuracy. A cumulative dose incidence map and DICOM header mining were used to determine the displayed reference point air kerma. Corrections for attenuation caused by the patient table and pad were measured and applied in order to determine the peak skin dose. The position and depth of the fetus was determined by ultrasound imaging and consultation with a radiologist. The data collected was used to determine a normalized uterus dose from Monte Carlo simulation data. Fetal dose values from this process were compared to other accepted calculation methods. Results: An accurate high-dose fetal dose estimate was made. Comparison to accepted legacy methods were were within 35% of estimated values. Conclusion: Modern data collection and reporting methods ease the process for estimation of fetal dose from interventional fluoroscopy exposures. Many aspects of the calculation can now be quantified rather than estimated, which should allow for a more accurate estimation of fetal dose.« less

Ion-recombination correction for different ionization chambers in high dose rate flattening-filter-free photon beams

NASA Astrophysics Data System (ADS)

Lang, Stephanie; Hrbacek, Jan; Leong, Aidan; Klöck, Stephan

2012-05-01

Recently, there has been an increased interest in flattening-filter-free (FFF) linear accelerators. Removal of the filter results in available dose rates up to 24 Gy min-1 (for nominal energy 10 MV in depth of maximum dose, a source-surface distance of 100 cm and a field size of 10×10 cm2). To guarantee accurate relative and reference dosimetry for the FFF beams, we investigated the charge collection efficiency of multiple air-vented and one liquid ionization chamber for dose rates up to 31.9 Gy min-1. For flattened beams, the ion-collection efficiency of all air-vented ionization chambers (except for the PinPoint chamber) was above 0.995. By removing the flattening filter, we found a reduction in collection efficiency of approximately 0.5-0.9% for a 10 MV beam. For FFF beams, the Markus chamber showed the largest collection efficiency of 0.994. The observed collection efficiencies were dependent on dose per pulse, but independent of the pulse repetition frequency. Using the liquid ionization chamber, the ion-collection efficiency for flattened beams was above 0.990 for all dose rates. However, this chamber showed a low collection efficiency of 0.940 for the FFF 10 MV beam at a dose rate of 31.9 Gy min-1. All investigated air-vented ionization chambers can be reliably used for relative dosimetry of FFF beams. The order of correction for reference dosimetry is given in the manuscript. Due to their increased saturation in high dose rate FFF beams, liquid ionization chambers appear to be unsuitable for dosimetry within these contexts.

Preserving Employee Privacy in Wellness.

PubMed

Terry, Paul E

2017-07-01

The proposed "Preserving Employee Wellness Programs Act" states that the collection of information about the manifested disease or disorder of a family member shall not be considered an unlawful acquisition of genetic information. The bill recognizes employee privacy protections that are already in place and includes specific language relating to nondiscrimination based on illness. Why did legislation expressly intending to "preserve wellness programs" generate such antipathy about wellness among journalists? This article argues that those who are committed to preserving employee wellness must be equally committed to preserving employee privacy. Related to this, we should better parse between discussions and rules about commonplace health screenings versus much less common genetic testing.

According to WHO estimates, 35% of global measles deaths in 2011 occurred in India. In 2013, India committed to a goal of measles elimination by 2020. Laboratory supported case based measles surveillance is an essential component of measles elimination strategies. Results from a case-based measles surveillance system in Pune district (November 2009 through December 2011) are reported here with wider implications for measles elimination efforts in India. Standard protocols were followed for case identification, investigation and classification. Suspected measles cases were confirmed through serology (IgM) or epidemiological linkage or clinical presentation. Data regarding age, sex, vaccination status were collected and annualized incidence rates for measles and rubella cases calculated. Of the 1011 suspected measles cases reported to the surveillance system, 76% were confirmed measles, 6% were confirmed rubella, and 17% were non-measles, non-rubella cases. Of the confirmed measles cases, 95% were less than 15 years of age. Annual measles incidence rate was more than 250 per million persons and nearly half were associated with outbreaks. Thirty-nine per cent of the confirmed measles cases were vaccinated with one dose of measles vaccine (MCV1). Surveillance demonstrated high measles incidence and frequent outbreaks in Pune where MCV1 coverage in infants was above 90%. Results indicate that even high coverage with a single dose of measles vaccine was insufficient to provide population protection and prevent measles outbreaks. An effective measles and rubella surveillance system provides essential information to plan, implement and evaluate measles immunization strategies and monitor progress towards measles elimination.

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.

Some parts of northern Surabaya are slum areas with dense populations, and the majority of the inhabitants are from low-income families. The condition of these areas is seemingly different from the fact that Surabaya city has won awards for its cleanliness, healthy environment preservation, and maintenance. This study aimed at turning the researched site into a clean and healthy environment. The research was conducted using a quasi-experiment technique with a non-randomized design and pretest-posttest procedures. The research subjects were 121 inhabitants who actively participated in the public commitment and psychoeducation program initiated by the researchers to learn and practice clean and healthy living behaviors. The statistical data showed that there was a substantial increase in the aspects of public commitment ( t -value = 4.008, p = 0.001) and psychoeducation ( t -value = 4.038, p = 0.001) to begin and maintain a clean and healthy living behaviors. A public commitment in the form of a collective declaration to keep learning and practicing a clean and healthy living behaviors were achieved. This commitment followed by psychoeducation aimed at introducing and exercising such behaviors was found to have effectively increased the research subjects' awareness to actively participate in preserving environmental hygiene. Developing communal behaviors toward clean and healthy living in inhabitants residing in an unhealthy slum area was a difficult task. Therefore, public commitment and psychoeducation must be aligned with the formulation of continuous habits demonstrating a clean and healthy living behaviors. These habits include the cessation of littering while putting trash in its place, optimizing the usage of public toilets, planting and maintaining vegetation around the area, joining and contributing to the "garbage bank" program, and participating in the Green and Clean Surabaya competition.

Proteomic Cornerstones of Hematopoietic Stem Cell Differentiation: Distinct Signatures of Multipotent Progenitors and Myeloid Committed Cells*

Regenerative tissues such as the skin epidermis, the intestinal mucosa or the hematopoietic system are organized in a hierarchical manner with stem cells building the top of this hierarchy. Somatic stem cells harbor the highest self-renewal activity and generate a series of multipotent progenitors which differentiate into lineage committed progenitors and subsequently mature cells. In this report, we applied an in-depth quantitative proteomic approach to analyze and compare the full proteomes of ex vivo isolated and FACS-sorted populations highly enriched for either multipotent hematopoietic stem/progenitor cells (HSPCs, LinnegSca-1+c-Kit+) or myeloid committed precursors (LinnegSca-1−c-Kit+). By employing stable isotope dimethyl labeling and high-resolution mass spectrometry, more than 5000 proteins were quantified. From biological triplicate experiments subjected to rigorous statistical evaluation, 893 proteins were found differentially expressed between multipotent and myeloid committed cells. The differential protein content in these cell populations points to a distinct structural organization of the cytoskeleton including remodeling activity. In addition, we found a marked difference in the expression of metabolic enzymes, including a clear shift of specific protein isoforms of the glycolytic pathway. Proteins involved in translation showed a collective higher expression in myeloid progenitors, indicating an increased translational activity. Strikingly, the data uncover a unique signature related to immune defense mechanisms, centering on the RIG-I and type-1 interferon response systems, which are installed in multipotent progenitors but not evident in myeloid committed cells. This suggests that specific, and so far unrecognized, mechanisms protect these immature cells before they mature. In conclusion, this study indicates that the transition of hematopoietic stem/progenitors toward myeloid commitment is accompanied by a profound change in processing of cellular resources, adding novel insights into the molecular mechanisms at the interface between multipotency and lineage commitment.

Ma, Shaozhuang; Xu, Xuehu; Trigo, Virginia; Ramalho, Nelson J C

2017-03-20

Purpose The purpose of this paper is twofold: first, to develop and test theory on how commitment human resource (HR) practices affect hospital professionals' job satisfaction that motivates them to generate desirable patient care and subsequently improve doctor-patient relationships (DPR) and second, to examine how commitment HR practices influence hospital managers and clinicians in different ways. Design/methodology/approach Using a cross-sectional survey, the authors collected data from 508 clinicians and hospital managers from 33 tertiary public hospitals in China. Structural equation model was employed to test the relationships of the variables in the study. Findings Commitment HR practices positively affect the job satisfaction of the healthcare professionals surveyed and a positive relationship is perceived between job satisfaction and DPR. Overall, the model shows a reversal on the strongest path linking job satisfaction and DPR whereby managers' main association operates through extrinsic job satisfaction while for clinicians it occurs through intrinsic satisfaction only. Practical implications DPR might be improved by applying commitment HR practices to increase healthcare professional's intrinsic and extrinsic satisfaction. In addition, while recognizing the importance of compensation and benefits to address the underpayment issue of Chinese healthcare professionals, empowerment and autonomy in work, and the use of subjects' expertise and skills may serve as stronger motivators for clinicians rather than hard economic incentives in achieving DPR improvements. Originality/value This study contributes to the small but growing body of research on human resource management (HRM) in the healthcare sector with new evidence supporting the link between commitment HR practice and work attitudes, as well as work attitudes and patient care from the perspective of clinicians and hospital managers. This study represents an initial attempt to examine the associations among commitment HR practices, job satisfaction and DPR in the Chinese healthcare sector. The findings provide evidence to support the value of commitment HR practices in Chinese hospital context, and demonstrate the importance of effective HRM in improving both hospital managers and clinicians' work attitudes.

The spent nuclear fuel reprocessing plant in Rokkasho, Japan, has been undergoing final testing since March 2006. During April 2006-October 2008, that spent fuel was cut and chemically processed, the plant discharged (129)I into the atmosphere and coastal waters. To study (129)I behaviour in brackish Lake Obuchi, which is adjacent to the plant, (129)I concentrations in aquatic biota were measured by accelerator mass spectrometry. Owing to (129)I discharge from the plant, the (129)I concentration in the biota started to rise from the background concentration in 2006 and was high during 2007-08. The (129)I concentration has been rapidly decreasing after the fuel cutting and chemically processing were finished. The (129)I concentration factors in the biota were higher than those reported by IAEA for marine organisms and similar to those reported for freshwater biota. The estimated annual committed effective dose due to ingestion of foods with the maximum (129)I concentration in the biota samples was 2.8 nSv y(-1). © The Author 2015.

The UNITAID Patent Pool Initiative: Bringing Patents Together for the Common Good.

2010-01-19

Developing and delivering appropriate, affordable, well-adapted medicines for HIV/AIDS remains an urgent challenge: as first-line therapies fail, increasing numbers of people require costly second-line therapy; one-third of ARVs are not available in pediatric formulations; and certain key first- and second-line triple fixed-dose combinations do not exist or sufficient suppliers are lacking. UNITAID aims to help solve these problems through an innovative initiative for the collective management of intellectual property (IP) rights - a patent pool for HIV medicines. The idea behind a patent pool is that patent holders - companies, governments, researchers or universities - voluntarily offer, under certain conditions, the IP related to their inventions to the patent pool. Any company that wants to use the IP to produce or develop medicines can seek a license from the pool against the payment of royalties, and may then produce the medicines for use in developing countries (conditional upon meeting agreed quality standards). The patent pool will be a voluntary mechanism, meaning its success will largely depend on the willingness of pharmaceutical companies to participate and commit their IP to the pool. Generic producers must also be willing to cooperate. The pool has the potential to provide benefits to all.

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.

An age dependent model for radium metabolism in man.

PubMed

Johnson, J R

1983-01-01

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.

Clinical research for neuropathies.

PubMed

Kaufmann, Petra

2012-05-01

The National Institutes of Health (NIH) has a long-standing commitment to neuropathy research. From 2005-2009, the NIH has committed US $115 million each year. A collaborative effort between researchers and patients can accelerate the translation of pre-clinical discoveries into better treatments for neuropathy patients. Clinical trials are needed to test these new treatments, but they can only be implemented in a timely fashion if patients with neuropathies are willing to participate. This perspective focuses on the value of having various outlets for informing both the patients and the physicians about existing clinical research opportunities and on the potential benefit of establishing patient registries to help with trial recruitment. Once data have been collected, there is a need to broadly share the data in order to inform future trials, and a first step would be to harmonize data collection by using Common Data Elements (CDEs). Published 2012. This article is a U.S. Government work and is in the public domain in the USA.

Hematopoietic stimulation by porphyrin photosensitizers (Invited Paper)

NASA Astrophysics Data System (ADS)

Levy, Julia G.; Hunt, David W. C.; Mitchell, David W.; Jamieson, Catriona H. M.

1992-06-01

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.

2014-07-15

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.

Joint NASA/USAF Airborne Field Mill Program - Operation and safety considerations during flights of a Lear 28 airplane in adverse weather

NASA Technical Reports Server (NTRS)

Fisher, Bruce D.; Phillips, Michael R.; Maier, Launa M.

1992-01-01

A NASA Langley Research Center Learjet 28 research airplane was flown in various adverse weather conditions in the vicinity of the NASA Kennedy Space Center from 1990-1992 to measure airborne electric fields during the Joint NASA/USAF Airborne Field Mill Program. The objective of this program was to characterize the electrical activity in various weather phenomena common to the NASA-Kennedy area in order to refine Launch Commit Criteria for natural and triggered lightning. The purpose of the program was to safely relax the existing launch commit criteria, thereby increasing launch availability and reducing the chance for weather holds and delays. This paper discusses the operational conduct of the flight test, including environmental/safety considerations, aircraft instrumentation and modification, test limitations, flight procedures, and the procedures and responsibilities of the personnel in the ground station. Airborne field mill data were collected for all the Launch Commit Criteria during two summer and two winter deployments. These data are now being analyzed.

Between and within couple-level factors associated with gay male couples’ investment in a sexual agreement

PubMed Central

Mitchell, Jason W.

2015-01-01

Sexual agreements are common among gay male couples, and between one-third and two-thirds of gay men acquire HIV while in a same-sex relationship. Studies have assessed whether agreements could be used for HIV prevention yet additional research is needed. By using dyadic data collected from 361 U.S. gay male couples, the present cross-sectional study sought to assess whether certain between and within couple-level relationship characteristics predict a partner's value in, commitment to, and satisfaction with an agreement. On average, couples with higher levels of constructive communication and relationship satisfaction and commitment were associated with partners who had higher levels of investment in the agreement. Within the couple, differences in commitment and investment of the relationship were also found to be negatively associated with partners’ investment toward an agreement. Implications are discussed for how sexual agreements may be used to develop new HIV prevention efforts for gay male couples. PMID:24327185

Health sciences librarians and mental health laws.

PubMed Central

Hartz, F R

1978-01-01

Two U.S. Supreme Court decisions, O'Connor v. Donaldson and Bounds v. Smith, hold important implications for health sciences librarians serving in mental health facilities. The first, O'Connor, with its many ancillary holdings, puts mental health personnel on notice that patients have certain basic rights, which courts all over the country will now be required to enforce. In Bounds the court has ruled that prison authorities must assist prison inmates in preparing and filing legal papers. The ruling will most likely benefit all mentally disabled prisoners, and future litigation may expand this category to include: (1) persons committed under the criminal code, (2) persons under involuntary commitment not related to the criminal code, and (3) persons voluntarily committed. A selective annotated bibliography, consisting of background readings in mental health and the law, basic rights, law library materials, and mental health legal services, has been compiled to help librarians establish and develop legal collections in anticipation of court decisions that will expand the conditions of Bounds to include all mentally disabled patients.

The path of patient loyalty and the role of doctor reputation.

PubMed

Torres, Eduardo; Vasquez-Parraga, Arturo Z; Barra, Cristobal

2009-01-01

Patient loyalty to doctors is relevant to medical services in which doctor-patient relationships are central and for which competition has increased in recent years. This study aims at understanding the process whereby patients develop loyalty to their doctor and doctor reputation has a moderating role. Based on a randomization of subjects, the study offers and tests an explanation chain representing key variables determining patient loyalty: patient commitment, trust and satisfaction, and doctor reputation. Primary data was collected using a structured questionnaire from a quota sample of regular patients in a large city in South America. The patients most committed to their doctor are more loyal to them. In turn, commitment is determined by patient trust, which is determined by patient satisfaction. Doctor reputation positively influences both patient trust and satisfaction. The explanation chain not only gives an account of how patient loyalty is formed; it also identifies a path health professionals can follow to secure patient loyalty.

IAEA-MEL has been engaged in an assessment programme related to radioactive waste dumping by the former USSR and other countries in the western North Pacific Ocean and its marginal seas. This paper focuses on the Sea of Japan and on estimation of collective doses from liquid radioactive wastes. The results from the Japanese-Korean-Russian joint expeditions are summarized, and collective doses for the Japanese population by the marine food pathway are estimated from liquid radioactive wastes dumped in the Sea of Japan and compared with those from global fallout and natural radionuclides. The collective effective dose equivalents by the annual intake of marine products caught in each year show a maximum a few years after the disposals. The total dose from all radionuclides reaches a maximum of 0.8 man Sv in 1990. Approximately 90% of the dose derives from 137Cs, most of which is due to consumption of fish. The total dose from liquid radioactive wastes is approximately 5% of that from global fallout, the contribution of which is below 0.1% of that of natural 210Po.

The effects of work alienation on organisational commitment, work effort and work-to-family enrichment.

PubMed

Tummers, Lars G; Den Dulk, Laura

2013-09-01

The aim of this study was to analyse the effects of work alienation on organisational commitment, work effort and work-to-family enrichment. There is substantial research on the effects of work alienation on passive job performance, such as organisational commitment. However, studies analysing work alienation on active performance, such as work effort, and outside work, such as work-to-family enrichment, are scarce. Two dimensions of work alienation are considered: powerlessness and meaninglessness. Hypotheses are tested using surveys collected among a national sample of midwives in the Netherlands (respondents: 790, response rate 61%). the findings indicate that work alienation (powerlessness and meaninglessness) influence organisational commitment, work effort and--to a lesser extent--work-to-family enrichment. High work meaninglessness, in particular, has negative effects on these outcomes. When people feel that they have no influence in their work (hence, when they feel 'powerless') and especially when the feel that their work is not worthwhile (when they feel 'meaningless') this has substantial negative effects. Managers should increase the meaningfulness that people attach to their work, thereby maintaining a high-quality workforce. Possible strategies include: (1) improving person-job fit, (2) developing high-quality relationships, (3) better communicating the results people help to deliver. © 2013 John Wiley & Sons Ltd.

Differences between children and adolescents who commit suicide and their peers: A psychological autopsy of suicide victims compared to accident victims and a community sample.

2012-01-04

The purpose of this study was to gain knowledge about the circumstances related to suicide among children and adolescents 15 years and younger. We conducted a psychological autopsy, collecting information from parents, hospital records and police reports on persons below the age of 16 who had committed suicide in Norway during a 12-year period (1993-2004) (n = 41). Those who committed suicide were compared with children and adolescents who were killed in accidents during the same time period (n = 43) and with a community sample. Among the suicides 25% met the criteria for a psychiatric diagnosis and 30% had depressive symptoms at the time of death. Furthermore, 60% of the parents of the suicide victims reported the child experienced some kind of stressful conflict prior to death, whereas only 12% of the parents of the accident victims reported such conflicts. One in four suicide victims fulfilled the criteria for a psychiatric diagnosis. The level of sub-threshold depression and of stressful conflict experienced by youths who committed suicide did not appear to differ substantially from that of their peers, and therefore did not raise sufficient concern for referral to professional help.

The influence of particle size distribution on dose conversion factors for radon progeny in the underground excavations of hard coal mine.

PubMed

Skubacz, Krystian; Wojtecki, Łukasz; Urban, Paweł

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.

241Am Ingrowth and Its Effect on Internal Dose

DOE PAGES

Konzen, Kevin

2016-07-01

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

MPC and ALI: their basis and their comparison

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

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

Natural radioactivity measurements and dosimetric evaluations in soil samples with a high content of NORM

2017-01-01

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).

In order to evaluate in depth the collective dose trend and its correlation with the effectiveness of the practical application of the ALARA principle in Spanish nuclear facilities, and base the different policy lines to promote this criteria, the CSN has fullfilled an analysis of the task related doses data over the period 1988-1992. Previously, the CSN had required to the utilities the compilation of their refuelling outage collective dose from 1988 according with a predeterminate number of tasks, in order to have available a representative and retrospective set of data in an homogeneous way and coherent with the internationalmore » data banks on occupational exposure in NPP, as the CEC and the NEA ones. The scope of this analysis was the following: first, the collective dose summaries for outage tasks and departments for PWR and for BWR, including the minimum, maximum and average dose (and statistics data) for 18 different refuelling outage tasks and 12 personal departments for each generation of each type of rector, the task and department related collective dose trends in each plant and in each generation, and second, the dose reduction techniques having been used during that period in each plant and the relative level of adoption. In this presentation the main results and conclusions of the first part of the study are reviewed for PWR.« less

According to the Bulgarian regulation for radiation protection at medical exposure, the National Centre of Radiobiology and Radiation Protection (NCRRP) is responsible for performing national dose surveys in diagnostic and interventional radiology and nuclear medicine and for establishing of national diagnostic reference levels (DRLs). The next national dose survey is under preparation to be performed in the period of 2015-16, with the aim to cover conventional radiography, mammography, conventional fluoroscopy, interventional and fluoroscopy guided procedures and CT. It will be performed electronically using centralised on-line data collection platform established by the NCRRP. The aim is to increase the response rate and to improve the accuracy by reducing human errors. The concept of the on-line dose data collection platform is presented. Radiological facilities are provided with a tool to determine local typical patient doses, and the NCRRP to establish national DRLs. Future work will include automatic retrieval of dose data from hospital picture archival and communicating system. The on-line data collection platform is expected to facilitate the process of dose audit and optimisation of radiological procedures in Bulgarian hospitals. © The Author 2015.

A realist evaluation of the management of a well- performing regional hospital in Ghana

PubMed Central

2010-01-01

Background Realist evaluation offers an interesting approach to evaluation of interventions in complex settings, but has been little applied in health care. We report on a realist case study of a well performing hospital in Ghana and show how such a realist evaluation design can help to overcome the limited external validity of a traditional case study. Methods We developed a realist evaluation framework for hypothesis formulation, data collection, data analysis and synthesis of the findings. Focusing on the role of human resource management in hospital performance, we formulated our hypothesis around the high commitment management concept. Mixed methods were used in data collection, including individual and group interviews, observations and document reviews. Results We found that the human resource management approach (the actual intervention) included induction of new staff, training and personal development, good communication and information sharing, and decentralised decision-making. We identified 3 additional practices: ensuring optimal physical working conditions, access to top managers and managers' involvement on the work floor. Teamwork, recognition and trust emerged as key elements of the organisational climate. Interviewees reported high levels of organisational commitment. The analysis unearthed perceived organisational support and reciprocity as underlying mechanisms that link the management practices with commitment. Methodologically, we found that realist evaluation can be fruitfully used to develop detailed case studies that analyse how management interventions work and in which conditions. Analysing the links between intervention, mechanism and outcome increases the explaining power, while identification of essential context elements improves the usefulness of the findings for decision-makers in other settings (external validity). We also identified a number of practical difficulties and priorities for further methodological development. Conclusion This case suggests that a well-balanced HRM bundle can stimulate organisational commitment of health workers. Such practices can be implemented even with narrow decision spaces. Realist evaluation provides an appropriate approach to increase the usefulness of case studies to managers and policymakers. PMID:20100330

The authors argue that dental curricula in Latin America are noted for providing highly technical and individualistic training that may fail to address society's problems or instil in the dentist the idea that he/she has a social responsibility to contribute to his/her community. This study's main objectives were to determine whether the curriculum and the faculty teaching practices of the School of Dentistry at the University of Chile contribute to its students' commitment to ethical and social responsibility. This was a qualitative study that investigated the perceptions of sixteen subjects (eight students and eight faculty members). Data were collected in thorough deep interviews. The interview process model conceptualised and organised the information into sets of dimensions and categories. The dimensions studied were ethical commitment and social responsibility. The categories assessed within ethical commitment were honesty, tolerance, responsibility and respect. In the social responsibility dimension, the categories were solidarity, teamwork and concern for and communication with the patient. Analysis of the textual data was performed using a method of content analysis based upon constructed qualitative matrices. Our results show that students and scholars alike realise that ethical commitment and a sense of social responsibility are not promoted in the curriculum. They do, however, recognise the importance of these qualities in dental practitioners. These results indicate that the current curriculum and teaching practices used in our School of Dentistry need to be reviewed and that programmes promoting professionals' commitment to their role in society need to be implemented. © 2012 John Wiley & Sons A/S.

Time use patterns among women with rheumatoid arthritis: association with functional limitations and psychological status.

PubMed

Katz, P; Morris, A

2007-03-01

This study assessed time use patterns among 375 women with rheumatoid arthritis (RA). We hypothesized that (i) as functional limitations increased, time use imbalances would occur (i.e. time needed for obligatory activities would conflict with time needed for productive and free-time activities) and (ii) time use imbalances would be associated with psychological distress. Time use estimates were obtained from written questionnaires; other study data were collected from annual telephone interviews. Activities were categorized as obligatory, committed or discretionary, as defined by Verbrugge. Time use estimates were aggregated to define number of obligatory (e.g. self-care) activities requiring >2 h/day and a number of committed and discretionary activities in which no time was spent each day. After adjusting for age, education, marital status and pain severity, women with more functional limitations were significantly more likely to spend >2 h/day in obligatory activities. As functional limitations increased, the proportion spending no time in each committed activity and many discretionary activities increased. Spending >2 h/day in obligatory activities was not significantly associated with poor psychological status, but spending no time in a greater number of committed and discretionary activities was associated with lower life satisfaction and higher levels of depressive symptoms. Having more severe functional limitations appears to shift time use patterns towards more time spent in obligatory activities and less time spent in committed and discretionary activities. These imbalances in time use were associated with psychological distress, highlighting the need for women with RA to maintain important productive, social and discretionary activities.

A strength of radiation protection programs generally has been endorsement and application of the ALARA principle. In Ontario Hydro, which currently operates 20 commercial size nuclear units, great strides have been made in the last three decades in reducing occupational radiation exposure per unit of electricity generated. This paper will discuss specific applications of elements of the overall ALARA program which have most contributed to dose reduction as the nuclear program has expanded. This includes such things as management commitment, ALARA application in the design phase and major rehabilitation work, the benefits of the self protection concept, a specific examplemore » of elimination (or reduction) of the source term and the importance of dose targets. Finally, it is concluded that the major opportunities for further improvements may lie in the area of information management.« less

In the Tokai No. 2 power plant of the Japan Atomic Power Company, about 80% of the annual dose equivalent is received during periodic maintenance outages. A project group for dose reduction was organized at the company`s headquarters in 1986; in 1988, they proposed a five-year program to reduce by half the collective dose of 4 person-Sv per normal outage work. To achieve the target dose value, some dose-reduction measures were undertaken, namely, permanent radiation shielding, decontamination, automatic, operating machines, and ALARA organization. As the result, the collective dose from normal outage work was 1.6 person-Sv in 1992, which wasmore » less than the initial target value.« less

Collective doses to man from dumping of radioactive waste in the Arctic Seas.

PubMed

Nielsen, S P; Iosjpe, M; Strand, P

1997-08-25

A box model for the dispersion of radionuclides in the marine environment covering the Arctic Ocean and the North Atlantic Ocean has been constructed. Collective doses from ingestion pathways have been calculated from unit releases of the radionuclides 3H, 60Co, 63Ni, 90Sr, 129I, 137Cs, 239Pu and 241Am into a fjord on the east coast of NovayaZemlya. The results show that doses for the shorter-lived radionuclides (e.g. 137Cs) are derived mainly from seafood production in the Barents Sea. Doses from the longer-lived radionuclides (e.g. 239Pu) are delivered through marine produce further away from the Arctic Ocean. Collective doses were calculated for two release scenarios, both of which are based on information of the dumping of radioactive waste in the Barents and Kara Seas by the former Soviet Union and on preliminary information from the International Arctic Sea Assessment Programme. A worst-case scenario was assumed according to which all radionuclides in liquid and solid radioactive waste were available for dispersion in the marine environment at the time of dumping. Release of radionuclides from spent nuclear fuel was assumed to take place by direct corrosion of the fuel ignoring the barriers that prevent direct contact between the fuel and the seawater. The second scenario selected assumed that releases of radionuclides from spent nuclear fuel do not occur until after failure of the protective barriers. All other liquid and solid radioactive waste was assumed to be available for dispersion at the time of discharge in both scenarios. The estimated collective dose for the worst-case scenario was about 9 manSv and that for the second scenario was about 3 manSv. In both cases, 137Cs is the radionuclide predicted to dominate the collective doses as well as the peak collective dose rates.

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.

Organizational readiness to change may be a key determinant of implementation success and a mediator of the effectiveness of implementation interventions. If organizational readiness can be reliably and validly assessed at the outset of a change initiative, it could be used to assess the effectiveness of implementation-support activities by measuring changes in readiness factors over time. We analyzed two waves of readiness-to-change survey data collected as part of a three-arm, randomized controlled trial to implement evidence-based health promotion practices in small worksites in low-wage industries. We measured five readiness factors: context (favorable broader conditions); change valence (valuing health promotion); information assessment (demands and resources to implement health promotion); change commitment (an intention to implement health promotion); and change efficacy (a belief in shared ability to implement health promotion). We expected commitment and efficacy to increase at intervention sites along with their self-reported effort to implement health promotion practices, termed wellness-program effort. We compared means between baseline and 15 months, and between intervention and control sites. We used linear regression to test whether intervention and control sites differed in their change-readiness scores over time. Only context and change commitment met reliability thresholds. Change commitment declined significantly for both control (-0.39) and interventions sites (-0.29) from baseline to 15 months, while context did not change for either. Only wellness program effort at 15 months, but not at baseline, differed significantly between control and intervention sites (1.20 controls, 2.02 intervention). Regression analyses resulted in two significant differences between intervention and control sites in changes from baseline to 15 months: (1) intervention sites exhibited significantly smaller change in context scores relative to control sites over time and (2) intervention sites exhibited significantly higher changes in wellness program effort relative to control sites. Contrary to our hypothesis, change commitment declined significantly at both Healthlinks and control sites, even as wellness-program effort increased significantly at HealthLinks sites. Regression to the mean may explain the decline in change commitment. Future research needs to assess whether baseline commitment is an independent predictor of wellness-program effort or an effect modifier of the HealthLinks intervention.

Therefore, a major concern of plasma properties collection and evaluation system is to create a sustainable and useful research environment for plasma data. The system has a commitment to provide not only numerical data but also bibliographic data (including DOI information). Originally, our collection data methods were done by manual data search. In some cases, it took a long time to find data. We will be find data more automatically and quickly than legacy methods by crawling or search engine such as Lucene.

Testing a pharmacist-patient relationship quality model among older persons with diabetes.

Considering recent changes to the Medicare program, pharmacists will have unique opportunities to be reimbursed for providing Medication Therapy Management Services to older persons with diabetes. A high-quality pharmacist-patient relationship can lay the foundation for effective provision of Medication Therapy Management Services and improved care in this cohort. To test a pharmacist-patient relationship quality model in a group of older persons with diabetes from the patient's perspective. Antecedents to relationship quality were pharmacist participative behavior/patient-centeredness of relationship, patient participative behavior, and pharmacist-patient interpersonal communication. Pharmacist-patient relationship commitment was the outcome of relationship quality studied. Data were collected via mailed questionnaire from a random sample of 600 community-dwelling adults in the United States who (1) were 65 years of age and older, (2) had type 1 or type 2 diabetes, (3) used at least one prescription medication to treat their diabetes, and (4) used some type of nonmail order pharmacy as their primary source of obtaining prescription medications. Model relationships were tested using path analysis. The adjusted response rate was 41.6% (221/531). The models explained 47% and 49% of the variance in relationship quality and relationship commitment, respectively. In the relationship quality model, pharmacist participative behavior/patient-centeredness of relationship (beta=.51, P<.001) and pharmacist-patient interpersonal communication (beta=.17, P=.008) had direct effects on relationship quality. In the relationship commitment model, relationship quality had a direct effect on relationship commitment (beta=.60, P<.001). Pharmacist participative behavior/patient-centeredness and pharmacist-patient interpersonal communication had indirect effects on relationship commitment through their effects on relationship quality, which is a mediator in the model. Results affirm findings from previous research showing that patients' perceptions of pharmacist participative behavior/patient-centeredness of relationship and pharmacist-patient interpersonal communication are positively related to perceptions of relationship quality. Also, relationship quality is a strong mediator between pharmacist participative behavior/patient-centeredness of relationship and relationship commitment, as well as between pharmacist-patient interpersonal communication and relationship commitment.

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

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.

Tracing the policy implementation of commitments made by national governments and other entities at the Third Global Forum on Human Resources for Health

We conducted a follow-up analysis of the implementation of the Human Resources for Health (HRH) commitments made by country governments and other actors at the Third Global Forum on HRH in 2013. Since then member states of the WHO endorsed Universal Health Coverage as the main policy objective whereby health systems strengthening, including reinforcement of the health workforce, can contribute to several Sustainable Development Goals. Now is the right time to trace the implementation of these commitments and to assess their contribution to broader global health objectives. The baseline data for this policy tracing study consist of the categorisation and analysis of the HRH commitments conducted in 2014. This analysis was complemented in application of the health policy triangle as its main analytical framework. An online survey and a guideline for semistructured interviews were developed to collect data. Information on the implementation of the commitments is available in 49 countries (86%). The need for multi-actor approaches for HRH policy development is universally recognised. A suitable political window and socioeconomic situation emerge as crucial factors for sustainable HRH development. However, complex crises in different parts of the world have diverted attention from investment in HRH development. The analysis indicates that investment in the health workforce and corresponding policy development relies on political leadership, coherent government strategies, institutional capacity and intersectoral governance mechanisms. The institutional capacity to shoulder such complex tasks varies widely across countries. For several countries, the commitment process provided an opportunity to invest in, develop and reform the health workforce. Nevertheless, the quality of HRH monitoring mechanisms requires more attention. In conclusion, HRH challenges, their different pathways and the intersectorality of the required responses are a concern for all the countries analysed. There is hence a need for national governments and stakeholders across the globe to share responsibilities and invest in this vital issue in a co-ordinated manner. PMID:29104768

Objectives. This study assessed patterns of displacement and human rights abuses among Kosovar refugees in Macedonia and Albania. Methods. Between April 19 and May 3, 1999, 1180 ethnic Albanian refugees living in 31 refugee camps and collective centers in Macedonia and Albania were interviewed. Results. The majority (68%) of participants reported that their families were directly expelled from their homes by Serb forces. Overall, 50% of participants saw Serb police or soldiers burning the houses of others, 16% saw Serb police or soldiers burn their own home, and 14% witnessed Serb police or soldiers killing someone. Large percentages of participants saw destroyed mosques, schools, or medical facilities. Thirty-one percent of respondents reported human rights abuses committed against their household members, including beatings, killings, torture, forced separation and disappearances, gunshot wounds, and sexual assault. Conclusions. The present findings confirm that Serb forces engaged in a systematic and brutal campaign to forcibly expel the ethnic Albanian population of Kosovo. In the course of these mass deportations, Serb forces committed widespread abuses of human rights against ethnic Albanians. PMID:11726386

Stress and counterproductive work behavior: multiple relationships between demands, control, and soldier indiscipline over time.

Cognitive Resource Theory (CRT) suggests that under high levels of stress, employees are more prone to committing indiscipline. As few studies have examined this relationship over time, the authors conducted a six-wave longitudinal study examining the relationship of soldiers' indiscipline with work demands and control. The study included archival data collected quarterly over 2 years from 1,701 soldiers representing 10 units in garrison (Germany and Italy), in training rotations (Grafenwoehr, Germany), and on peacekeeping deployments (Kosovo, Kuwait). No main effects were found for work overload, and the findings for the moderating effects of control were contradictory. Within each time point, as work overload increased, soldiers who felt less control committed more indiscipline, supporting CRT. Over time, however, as work overload increased, soldiers who perceived less control 6 months earlier committed less indiscipline. Additionally, the authors found reverse causal effects for control such that prior perceptions of a lack of control were associated with indiscipline and prior incidents of indiscipline with less control.
