Chronic pain, work performance and litigation.
Blyth, Fiona M; March, Lyn M; Nicholas, Michael K; Cousins, Michael J
2003-05-01
The overall population impact of chronic pain on work performance has been underestimated as it has often been described in terms of work-related absence, excluding more subtle effects that chronic pain may have on the ability to work effectively. Additionally, most studies have focussed on occupational and/or patient cohorts and treatment seeking, rather than sampling from the general population. We undertook a population-based random digit dialling computer-assisted telephone survey with participants randomly selected within households in order to measure the impact of chronic pain on work performance. In addition, we measured the association between pain-related disability and litigation. The study took place in Northern Sydney Health Area, a geographically defined urban area of New South Wales, Australia, and included 484 adults aged 18 or over with chronic pain. The response rate was 73.4%. Working with pain was more common (on an average 83.8 days in 6 months) than lost work days due to pain (4.5 days) among chronic pain participants in full-time or part-time employment. When both lost work days and reduced-effectiveness work days were summed, an average of 16.4 lost work day equivalents occurred in a 6-month period, approximately three times the average number of lost work days. In multiple logistic regression modelling with pain-related disability as the dependent variable, past or present pain-related litigation had the strongest association (odds ratio (OR)=3.59, P=0.001). In conclusion, chronic pain had a larger impact on work performance than has previously been recognised, related to reduced performance while working with pain. A significant proportion were able to work effectively with pain, suggesting that complete relief of pain may not be an essential therapeutic target. Litigation (principally work-related) for chronic pain was strongly associated with higher levels of pain-related disability, even after taking into account other factors associated with poor functional outcomes.

Workplace safety performance is computed using frequency rate (FR) and severity rate (SR). Only work time lost due to occupational incidents that need to be reported is counted. FR and SR are the 2 most important safety performance indicators that are applied universally; however, calculations differ from country to country. All injuries and time lost should be considered while calculating safety performance. The extent of severity does not matter as every incident is counted. So, a new factor has to be defined; it should be based on the hours or days lost due to each occupational incident, irrespective of its severity. The new safety performance factor is defined as the average human-hour unit lost due to occupational accidents/incidents, including fatalities, first-aid incidents, bruises and cuts. The formula is simple and easy to apply.

The severity of non-fatal work-related injuries has seldom been examined among young workers. We estimated the extent and distribution of workdays lost due to non-fatal work injuries using compensation data. Data are from the Brazilian Institute of Social Insurance, for 2006. The study population is comprised of all insured workers of age 16-24. Descriptive statistics reflect workdays lost due to health-related disability, according to sex, age group, wage, and trade. Out of 4.8 million insured workers ages 16-24 years, we estimated 1,282,940 workdays lost. We observed a larger number of median workdays lost among males age 20-24 in retail and service trades (83 days) and among 16-19-year-old females in the agriculture/fish/forestry/cattle (142 days). Young workers experience a heavy burden of work-related injuries. Disability workdays may compromise school attendance and performance. Other potential impacts affect productivity and social insurance costs. Copyright © 2012 Wiley Periodicals, Inc.

Few studies have examined the impact of 'sit less, move more' interventions on workplace performance. This study assessed the short and mid-term impacts of and patterns of change within, a 19-week workplace web-based intervention (Walk@WorkSpain; W@WS; 2010-11) on employees´ presenteeism, mental well-being and lost work performance. A site randomised control trial recruited employees at six Spanish university campuses (n = 264; 42 ± 10 years; 171 female), assigned by worksite and campus to an Intervention (IG; used W@WS; n = 129; 87 female) or an active Comparison group (A-CG; pedometer, paper diary and self-reported sitting time; n = 135; 84 female). A linear mixed model assessed changes between the baseline, ramping (8 weeks), maintenance (11 weeks) and follow-up (two months) phases for the IG versus A-CG on (i) % of lost work productivity (Work Limitations Questionnaire; WLQ); (ii) three scales for presenteeism (WLQ) assessing difficulty meeting scheduling demands (Time), performing cognitive and inter-personal tasks (Mental-Interpersonal) and decrements in meeting the quantity, quality and timeliness of completed work (Output); and (iii) mental well-being (Warwick-Edinburgh Mental Well-being Scale). T-tests assessed differences between groups for changes on the main outcomes. In the IG, a multivariate logistic regression model identified patterns of response according to baseline socio-demographic variables, physical activity and sitting time. There was a significant 2 (group) × 2 (program time points) interaction for the Time (F [3]=8.69, p = 0.005), Mental-Interpersonal (F [3]=10.01, p = 0.0185), Output scales for presenteeism (F [3]=8.56, p = 0.0357), and for % of lost work performance (F [3]=10.31, p = 0.0161). Presenteeism and lost performance rose significantly in both groups across all study time points; after baseline performance was consistently better in the IG than in the A-CG. Better performance was linked to employees being more active (Time, p = 0.041) and younger (Mental-interpersonal, p = 0.057; Output, p = 0.017). Higher total sitting time during nonworking days (Mental-interpersonal, p = 0.019) and lower sitting time during workdays (WLQ Index, p = 0.013) also improved performance. Versus an active comparison condition, a 'sit less, move more` workplace intervention effectively reduced an array of markers of lost workday productivity.

To estimate and compare lost work hours attributable to presenteeism, defined as reduced productivity while working, in individuals with osteoarthritis (OA) or rheumatoid arthritis (RA), according to 4 instruments. In our prospective study, 250 workers with OA (n = 130) or RA (n = 120) were recruited from community and clinical sites. Lost hours due to presenteeism at baseline were estimated using the Health and Labor Questionnaire (HLQ), the Work Limitations Questionnaire (WLQ), the World Health Organization's Health and Work Performance Questionnaire (HPQ), and the Work Productivity and Activity Impairment Questionnaire (WPAI). Only those respondents working over the past 2 weeks were included. Repeated-measures ANOVA was used to compare the lost-time estimates, according to each instrument. Of the 212 respondents included in the analyses, the frequency of missing and "0" values among the instruments was different (17% and 61% for HLQ, 8% and 5% for WLQ, 1% and 16% for HPQ, 0% and 27% for WPAI, respectively). The average numbers of lost hours (SD) per 2 weeks due to presenteeism using HLQ, WLQ, HPQ, and WPAI were 1.6 (3.9), 4.0 (3.9), 13.5 (12.5), and 14.2 (16.7). The corresponding costs for the 2-week period were CAN$30.03, $83.05, $284.07, and $285.10. The differences in the lost-hour estimates according to instruments were significant (p < 0.001). Among individuals with arthritis, estimates of productivity losses while working vary widely according to the instruments chosen. Further research on instrument design and implications for a standardized approach to estimate lost time due to presenteeism is needed.

To estimate the prevalence and associations of broadly defined (i.e., meeting full ICD-10, DSM-IV, or RDC/ICSD-2 inclusion criteria) insomnia with work performance net of comorbid conditions in the America Insomnia Survey (AIS). Cross-sectional telephone survey. National sample of 7,428 employed health plan subscribers (ages 18+). None. Broadly defined insomnia was assessed with the Brief Insomnia Questionnaire (BIQ). Work absenteeism and presenteeism (low on-the-job work performance defined in the metric of lost workday equivalents) were assessed with the WHO Health and Work Performance Questionnaire (HPQ). Regression analysis examined associations between insomnia and HPQ scores controlling 26 comorbid conditions based on self-report and medical/pharmacy claims records. The estimated prevalence of insomnia was 23.2%. Insomnia was significantly associated with lost work performance due to presenteeism (χ² (1) = 39.5, P < 0.001) but not absenteeism (χ² (1) = 3.2, P = 0.07), with an annualized individual-level association of insomnia with presenteeism equivalent to 11.3 days of lost work performance. This estimate decreased to 7.8 days when controls were introduced for comorbid conditions. The individual-level human capital value of this net estimate was $2,280. If we provisionally assume these estimates generalize to the total US workforce, they are equivalent to annualized population-level estimates of 252.7 days and $63.2 billion. Insomnia is associated with substantial workplace costs. Although experimental studies suggest some of these costs could be recovered with insomnia disease management programs, effectiveness trials are needed to obtain precise estimates of return-on-investment of such interventions from the employer perspective.

Most studies that investigate the impact of mental disorders on work performance have been conducted in Western countries, but this study examines the impact of common mental disorders on sick leave and on-the-job work performance in a community sample of Japanese workers. Data from the World Mental Health Japan survey were analyzed. A subsample of 530 workers aged 20-60years were interviewed using the WHO Composite International Diagnostic Interview 3.0. The WHO Health and Work Performance Questionnaire, was used to assess sick days and on-the-job work performance for the previous 30days. Linear regression was used to estimate the impact of mental disorders on these indicators of work performance over 12months. Mood disorders, including major depressive disorder, and alcohol abuse/dependence were significantly associated with decreased on-the-job performance. There were no significant associations between mental disorders and sick/absent days. Consistent with previous studies, major depression has a great impact on on-the-job work performance in Japan. The lost productivity was estimated at approximately 28-30 lost days per year. A similar decrease in on-the-job work performance was found for alcohol abuse/dependence, which is stronger than that in other countries, probably attributable to greater tolerance of problematic drinking at Japanese worksites.

When some entropy is transferred, by means of a reversible engine, from a hot heat source to a colder one, the maximum efficiency occurs, i.e. the maximum available work is obtained. Similarly, a reversible heat pumps transfer entropy from a cold heat source to a hotter one with the minimum expense of energy. In contrast, if we are faced with non-reversible devices, there is some lost work for heat engines, and some extra work for heat pumps. These quantities are both related to entropy production. The lost work, i.e. ? , is also called 'degraded energy' or 'energy unavailable to do work'. The extra work, i.e. ? , is the excess of work performed on the system in the irreversible process with respect to the reversible one (or the excess of heat given to the hotter source in the irreversible process). Both quantities are analysed in detail and are evaluated for a complex process, i.e. the stepwise circular cycle, which is similar to the stepwise Carnot cycle. The stepwise circular cycle is a cycle performed by means of N small weights, dw, which are first added and then removed from the piston of the vessel containing the gas or vice versa. The work performed by the gas can be found as the increase of the potential energy of the dw's. Each single dw is identified and its increase, i.e. its increase in potential energy, evaluated. In such a way it is found how the energy output of the cycle is distributed among the dw's. The size of the dw's affects entropy production and therefore the lost and extra work. The distribution of increases depends on the chosen removal process.

To lay groundwork for identifying patterns of injury etiology, we sought to describe injury experience associated with types of work performed at construction sites by examining workers' compensation (WC) claims for the 32,081 construction workers who built Denver International Airport (DIA). Injury rates and WC payment rates were calculated for 25 types of work based on claims and payroll data reported to DIA's owner-controlled insurance program according to National Council on Compensation Insurance job classifications. By linking DIA claims with corresponding lost-work-time (LWT) claims filed with Colorado's Workers' Compensation Division, we were also able to obtain and examine both total and median lost days for each type of work. Injury experience varied widely among the types of construction work. Workers building elevators and conduits and installing glass, metal, or steel were at particularly high risk of both LWT and non-LWT injury. Median days lost by injured workers was highest (202 days) for driving/trucking. Median days lost for most types of work was much greater than previously reported for construction: 40 days or more for 18 of the 25 types of work analyzed. WC payment rates reflect both number and severity of injuries and were generally not significantly different from expected losses. They were, however, significantly higher than expected for driving/trucking, metal/steel installation, inspection/analysis, and elevator construction. Analysis of injury data by type of work allows targeting of safety resources to high risk construction work and would be useful in prospective surveillance at large construction sites with centrally administered workers' compensation plans.

Introduction to ergonomics for healthcare workers.
Waters, Thomas R
2010-01-01
Healthcare workers who handle and move patients as part of their jobs suffer a disproportionately high number of work-related musculoskeletal disorders (MSDs). The majority of reported work-related MSDs are back pain cases that result in significant numbers of lost work days. It is likely that these lost workdays have a substantial impact on the quality and cost of health care. Patient care ergonomics can reduce the risk of work-related MSDs by helping safety experts design the work so it can be safely performed by most workers. This article provides a general overview of ergonomics--what it is, how it can be used to help design safe work, and why all healthcare workers and administrators should know and understand how excessive work demands can lead to increased risk of work-related MSDs. The article will also explain technological solutions that can be implemented to reduce the risk of work-related MSDs for healthcare workers.
The impact of influenza on working days lost: a review of the literature.
Keech, Martin; Beardsworth, Paul
2008-01-01
Seasonal influenza is a prevalent and highly contagious acute respiratory disease that, year on year, results in increased morbidity and mortality on a global scale. Because of the widespread and debilitating nature of the disease, annual influenza epidemics result in substantial workplace absenteeism, and the associated cost of lost productivity is a significant component of the substantial financial burden of the disease to society. The objective of this review was to identify studies that had attempted to quantify the impact of influenza upon otherwise healthy adults in terms of working days lost associated with an episode of influenza.Studies were included if they reported estimates of working days lost due to clinical, physician and/or self-diagnosis in adult patients or their dependants, or where this figure could be estimated from the data. Searches were conducted in MEDLINE, EMBASE, BIOSIS and the Cochrane Collaboration for articles published since 1995 in English, French or German. Of the 289 papers identified in the search, 28 (9.7%) met the inclusion criteria. The studies, involving study sites in North America, Western Europe, Asia and Australia, were categorized into three groups: (i) those reporting influenza diagnoses confirmed by laboratory testing, i.e. studies where influenza was the unambiguous cause of the working days lost (n = 7 studies reported in ten publications); (ii) those where influenza was confirmed by a physician without an accompanying laboratory test (n = 4 studies); and (iii) those where influenza was self-reported by study participants (n = 14 studies). Qualitative reporting of results was performed because of the large degree of heterogeneity observed between studies, potentially complicating the interpretation of any meta-analysis.The results from studies involving a laboratory-confirmed influenza diagnosis suggested that the mean number of working days lost ranged between 1.5 and 4.9 days per episode. Those papers that detailed working days lost per episode following physician diagnosis of influenza reported a range of 3.7-5.9 days per episode. Finally, estimates from papers reporting working days lost per episode of self-reported influenza ranged from <1 day to 4.3 days per episode.Influenza imposes a significant burden on society, and this review highlights the significant economic impact it causes, i.e. the loss of productivity caused by both absenteeism and by staff functioning at reduced capacity even after they have returned to work. A number of prophylaxis and treatment options exist for influenza and should be given serious consideration in an attempt to reduce the economic burden on society.
Allergic rhinitis and the common cold--high cost to society.
Hellgren, J; Cervin, A; Nordling, S; Bergman, A; Cardell, L O

The common cold and allergic rhinitis constitute a global health problem that affects social life, sleep, school and work performance and is likely to impose a substantial economic burden on society because of absence from work and reduced working capacity. This study assesses the loss of productivity as a result of both allergic rhinitis and the common cold in the Swedish working population. Four thousand questionnaires were sent to a randomized adult population, aged 18-65 years, in Sweden, stratified by gender and area of residence (metropolitan area vs rest of the country). The human capital approach was used to assign monetary value to lost productivity in terms of absenteeism (absence from work), presenteeism (reduced working capacity while at work) and caregiver absenteeism (absence from work to take care of a sick child). Thousand two hundred and thirteen individuals responded, response rate 32%. The mean productivity loss was estimated at 5.1 days or euro 653 per worker and year, yielding a total productivity loss in Sweden of euro 2.7 billion a year. Of the total costs, absenteeism (44%) was the dominant factor, followed by presenteeism (37%) and caregiver absenteeism (19%). Poisson regression analyses revealed that women, people in the 18-29 year age group, and respondents with 'doctor-diagnosed asthma' reported more lost days than the rest of the group. In Sweden, the cost of rhinitis is euro 2.7 billion a year in terms of lost productivity. A reduction in lost productivity of 1 day per individual and year would potentially save euro 528 million.

Objective To estimate the total annual societal cost of uterine fibroids in the United States, based on direct and indirect costs, including associated obstetric complications. Study Design A systematic review of the literature was conducted to estimate the number of women seeking treatment for symptomatic fibroids annually, the costs of medical and surgical treatment, work lost and obstetric complications attributable to fibroids. Total annual costs were converted to 2010 U.S. dollars. A sensitivity analysis was performed. Results The estimated annual direct costs (surgery, hospital admissions, outpatient visits, medications) were $4.1 to $9.4 billion. Estimated lost work costs ranged from $1.55 to $17.2 billion annually. Obstetric outcomes attributed to fibroids resulted in a cost of $238 million to $7.76 billion annually. Uterine fibroids were estimated to cost the US $5.9 to $34.4 billion annually. Conclusions Obstetric complications associated with fibroids contributed significantly to their economic burden. Lost work costs may account for the largest proportion of societal costs due to fibroids. PMID:22244472
[Work days lost due to health problems in industry].
Yano, Sylvia Regina Trindade; Santana, Vilma Sousa
2012-05-01
This cross-sectional study estimated the prevalence of work days lost due to health problems and associated factors among industrial workers. The study population was a simple random cluster sample of 3,403 workers from 16 to 65 years of age in the city of Salvador, Bahia State, Brazil. Data were collected with individual home interviews. Among industrial workers, one-year prevalence of work days lost to health problems was 12.5%, of which 5.5% were directly work-related and 4.1% aggravated by work. There were no statistically significant differences when compared to other worker categories. Self-perceived workplace hazards, history of work-related injury, and poor self-rated health were associated with work days lost due to work-related injuries/diseases. The findings showed that work days lost are common among both industrial and non-industrial workers, thereby affecting productivity and requiring prevention programs.

Employee assistance programs, drug testing, and workplace injury.

Little is known about the effects of employee assistance programs (EAPs) on occupational injuries. Multivariate regressions probed a unique data set that linked establishment information about workplace anti-drug programs in 1988 with occupational injury rates for 1405 establishments. EAPs were associated with a significant reduction in both no-lost-work and lost-work injuries, especially in the manufacturing and transportation, communication and public utilities industries (TCPU). Lost-work injuries were more responsive to specific EAP characteristics, with lower rates associated with EAPs staffed by company employees (most likely onsite). Telephone hotline services were associated with reduced rates of lost-work injuries in manufacturing and TCPU. Drug testing was associated with reductions in the rate of minor injuries with no lost work, but had no significant relationship with lost-work injuries. This associational study suggests that EAPs, especially ones that are company-staffed and ones that include telephone hotlines, may prevent workplace injuries. Copyright © 2016.

Validation of the work and health interview.

Instruments that measure the impact of illness on work do not usually provide a measure that can be directly translated into lost hours or costs. We describe the validation of the Work and Health Interview (WHI), a questionnaire that provides a measure of lost productive time (LPT) from work absence and reduced performance at work. A sample (n = 67) of inbound phone call agents was recruited for the study. Validity of the WHI was assessed over a 2-week period in reference to workplace data (i.e. absence time, time away from call station and electronic continuous performance) and repeated electronic diary data (n = 48) obtained approximately eight times a day to estimate time not working (i.e. a component of reduced performance). The mean (median) missed work time estimate for any reason was 11 (8.0) and 12.9 (8.0) hours in a 2-week period from the WHI and workplace data, respectively, with a Pearson's (Spearman's) correlation of 0.84 (0.76). The diary-based mean (median) estimate of time not working while at work was 3.9 (2.8) hours compared with the WHI estimate of 5.7 (3.2) hours with a Pearson's (Spearman's) correlation of 0.19 (0.33). The 2-week estimate of total productive time from the diary was 67.2 hours compared with 67.8 hours from the WHI, with a Pearson's (Spearman's) correlation of 0.50 (0.46). At a population level, the WHI provides an accurate estimate of missed time from work and total productive time when compared with workplace and diary estimates. At an individual level, the WHI measure of total missed time, but not reduced performance time, is moderately accurate.
Is seat belt use associated with fewer days of lost work after motor vehicle collisions?

Seat belt use has consistently been shown to reduce motor vehicle collision (MVC)-related morbidity and mortality. The goal of this study is to determine whether seat belt use is associated with fewer lost workdays among occupants involved in MVCs. The 1995 to 2000 National Automotive Sampling System (NASS) data files were used. The NASS is a national probability sample of passenger vehicles involved in police-reported tow-away MVCs. Occupants' lost workdays, which are routinely collected as part of an NASS investigation, were compared according to seat belt use. During 1995 to 2000 in the United States, surviving occupants involved in MVCs lost a total of 42.1 million workdays (approximately 7.0 million lost workdays per year; 2.4 lost workdays per person). The overall difference in lost workdays between the belted and unbelted occupants was 1.59 days (1.99 days vs. 3.58 days, respectively; p < 0.001). After adjusting for potentially confounding factors, belted occupants had 1.52 fewer lost workdays compared with unbelted occupants (p < 0.001). This translates to an estimated 7.3 million lost workdays and an associated $566 million in lost wages and $1.25 billion in work-place costs attributable to lack of seat belt use in the United States during 1995 to 2000. Lost workdays attributable to MVCs in the United States have sizable financial implications. Furthermore, seat belt use significantly reduces lost time at work and is associated with a significant cost savings. The national impact of unbelted driving on work productivity is dramatic, and further efforts to promote appropriate seat belt use should continue as part of the national safety agenda.
Using an atom interferometer to take the Gedanken out of Feynman's Gedankenexperiment

We give a description of two experiments performed in an atom interferometer at MIT. By scattering a single photon off of the atom as it passes through the interferometer, we perform a version of a classic gedankenexperiment, a demonstration of a Feynman light microscope. As path information about the atom is gained, contrast in the atom fringes (coherence) is lost.

Road traffic injuries (RTIs) are increasingly contributing to the burden of disease in sub-Saharan Africa, yet little is known about the economic consequences and disability associated with them. To explore cost and disability consequences of RTIs in Nigeria. A population-based survey using two-stage stratified cluster sampling. SUBJECT/SETTING: Information on care-seeking choice, cost of treatment, ability to work, reduction in earnings, and disability were collected on 127 subjects who had suffered an RTI, of 3082 study subjects in seven Nigerian states. Univariate analysis was used to estimate frequency of disability, types of care sought, and trends for work lost, functional ability and cost of treatment. Unadjusted bivariate analysis was performed to explore care-seeking, cost of care, and work lost among disabled and non-disabled people. RTIs resulted in disability for 29.1% of subjects, while 13.5% were unable to return to work. Of the disabled people, 67.6% were unable to perform activities of daily living, 16.7% consequently lost their jobs, and 88.6% had a reduction in earnings. Private physician and hospital treatment were the most common forms of initial treatment sought, but traditional treatment was the most common second form of care sought. Average direct costs of informal and formal treatment were US$6.65 and US$35.64, respectively. Disabled people were more likely to seek formal care (p=0.003) and be unable to work (p=0.002). Economic and functional ramifications must be included in the spectrum of consequences of RTIs to fully appreciate the extent of the burden of disease, implying that health systems should not only address the clinical consequences of RTIs, but the financial ones as well.

Happy, healthy, and productive: the role of detachment from work during nonwork time.
Fritz, Charlotte; Yankelevich, Maya; Zarubin, Anna; Barger, Patricia

Mentally distancing oneself from work during nonwork time can help restore resources lost because of work demands. In this study, we examined possible outcomes of such psychological detachment from work, specifically well-being and job performance. Although employees may need to mentally detach from work to restore their well-being, high levels of detachment may require a longer time to get back into "working mode," which may be negatively associated with job performance. Our results indicate that higher levels of self-reported detachment were associated with higher levels of significant other-reported life satisfaction as well as lower levels of emotional exhaustion. In addition, we found curvilinear relationships between psychological detachment and coworker reported job performance (task performance and proactive behavior). Thus, although high psychological detachment may enhance employee well-being, it seems that medium levels of detachment are most beneficial for job performance.

When national pharmacoeconomic guidelines are compared, different recommendations are identified on how to identify, measure and value lost productivity, leading to difficulties when comparing lost productivity estimates across countries. From a transferability point of view, the question arises of whether differences between countries regarding lost productivity are the result of using different calculation methods (methodological differences) or of other between-country differences. When lost productivity data differ significantly across countries, the transferability of lost productivity data across countries is hindered. The objective of this study was to investigate whether country of residence has a significant influence on the quantity of lost productivity among patients with rheumatic disorders. Confounding factors that might differ between countries were corrected for, while the methodology used to identify and measure lost productivity was kept the same. This question was investigated by means of an online questionnaire filled out by 200 respondents with a rheumatic disorder per country in four European countries, namely the Netherlands, the UK, Germany and France. In addition to those regarding lost productivity, the questionnaire contained questions about patient characteristics, disability insurance, disease characteristics, quality of life and job characteristics as these variables are expected to influence lost productivity in terms of absenteeism and presenteeism. The data were analysed by regression analyses, in which different components - being absent in last 3 months, number of days absent and presenteeism - of lost productivity were the main outcome measures and other variables, such as gender, impact of disease, shift work, job control, partial disability and overall general health, were corrected for. The results showed that country sometimes has a significant influence on lost productivity and that other variables such as, for example, age, disease severity, number of contract hours, decision latitude, experienced health (as reported on the visual analogue scale) and partial disability, also influence lost productivity. A significant influence of country of residence was found on the variables 'being absent in the last three months', 'number of days absent' and 'quality of work on the last working day'. However, country did not influence 'quantity of work on the last working day' and 'overall presenteeism on the last working day'. It can be concluded that country has a significant influence on lost productivity among patients with rheumatic disorders, when corrected for other variables that have an influence on absenteeism and presenteeism. Transferring lost productivity data across countries without adaptation is hindered by the significant differences between countries in this patient group. As a result, transferring lost productivity data, being either monetary values or volumes of productivity losses, between countries can give wrong estimations of the cost effectiveness of treatments.

Chronic rhinosinusitis (CRS) is associated with a significant loss of patient productivity that costs billions of dollars every year. Smoking is associated with worsening sinonasal symptoms, but its effect on lost productivity in CRS patients has yet to be described. Therefore, we sought to determine the association between smoking and productivity in patients with CRS. Prospective cross-sectional cohort study of 140 patients with CRS. Sinonasal symptom severity was measured using the 22-item Sino-Nasal Outcomes Test. Lost productivity was assessed by asking participants how many days of work and/or school they missed in the last 3 months due to CRS. Associations were sought between lost productivity and smoking. Participants missed a mean of 3.0 days (standard deviation = 12.8 days) of work or school due to CRS. Having any history of smoking was associated with 6 days of lost productivity due to CRS (adjusted β = 6.20, 95% confidence interval [CI]: 0.64 to 11.77, P = .031). Although the number of active smokers in our study cohort was very small (N = 6), we performed a univariate association between smoking status, considering former smokers and active smokers separately, and found that active smoking (β = 11.75, 95% CI: 2.11 to 21.40, P = .018) had a much larger impact on CRS-related productivity loss than that experienced by former smokers (β = 4.45, 95% CI: -0.32 to 9.23, P = .070). Smoking (likely driven by active smoking) is independently associated with missed days of work or school in patients with CRS. Further study is needed to determine whether interventions directed at smoking may impact CRS-related productivity loss. 2c Laryngoscope, 127:1742-1745, 2017. © 2017 The American Laryngological, Rhinological and Otological Society, Inc.

During entanglement in fishing gear, dolphins can suffer abrasions and amputations of flukes and fins. As a result, if the dolphin survives the ordeal, swimming performance is altered. Current rehabilitation technques is the use of prosthesis to regain swimming ability. In this work, analyses are focused on two dolphins with locomotive impairment; Winter (currently living in Clearwater Marine Aquarium in Florida) and Fuji (lived in Okinawa Churaumi Aquarium in Japan). Fuji lost about 75% of its fluke surface to necrosis (death of cells) and Winter lost its tail due to amputation. Both dolphins are aided by prosthetic tails that mimic the shape of a real dolphin tail. Using 3D surface reconstruction techniques and a high fidelity Computational Fluid Dynamics (CFD) flow solver, we were able to elucidate the kinematics and hydrodynamics and fluke deformation of these swimmers to clarify the effectiveness of prostheses in helping the dolphins regain their swimming ability. Associated with the performance, we identified distinct features in the wake structures that can explain this gap in the performance compared to a healthy dolphin.

With the increased emphasis on vehicle weight reduction, production of near-net shape components by lost foam casting will make significant inroad into the next-generation of engineering component designs. The lost foam casting process is a cost effective method for producing complex castings using an expandable polystyrene pattern and un-bonded sand. The use of un-bonded molding media in the lost foam process will impose less constraint on the solidifying casting, making hot tearing less prevalent. This is especially true in Al-Mg and Al-Cu alloy systems that are prone to hot tearing when poured in rigid molds partially due to their longmore » freezing range. Some of the unique advantages of using the lost foam casting process are closer dimensional tolerance, higher casting yield, and the elimination of sand cores and binders. Most of the aluminum alloys poured using the lost foam process are based on the Al-Si system. Very limited research work has been performed with Al-Mg and Al-Cu type alloys. With the increased emphasis on vehicle weight reduction, and given the high-strength-to-weight-ratio of magnesium, significant weight savings can be achieved by casting thin-wall (≤ 3 mm) engineering components from both aluminum- and magnesium-base alloys.« less
Hours Lost to Planned and Unplanned Dental Visits Among US Adults.

2018-01-11
Poor oral health is associated with lost hours at work or school, which may affect a person's productivity. The objective of our study was to estimate work or school hours lost to dental visits among adults aged 18 and older by the types of visits (emergency or unplanned; routine, planned, or orthodontic; or cosmetic) and to determine the factors associated with hours lost. We used the most recent Oral Health Supplement data, from the 2008 National Health Interview Survey (NHIS), to estimate the total hours lost at work or school for dental visits among adults in the United States. The associations of the hours lost in unplanned and planned dental visits with socioeconomic characteristics, oral health status, and affordability were calculated. We used χ 2 tests and logistic regression to determine associations at P < .05. An average of 320.8 million work or school hours were lost annually for dental care in the United States, of which 92.4 million hours were for emergency (unplanned) care (0.99 h/adult), 159.8 million for routine (planned) care or orthodontic care (1.71 h/adult), and 68.6 million for cosmetic care (0.73 h/adult). Adults with poor oral health were more likely to lose one or more hours in unplanned dental visits (OR = 5.60; 95% confidence interval [CI], 3.25-9.63) than those who reported very good oral health. Not being able to afford dental care was positively associated with more work hours lost in unplanned care (odds ratio [OR] = 2.56; 95% CI, 1.76-3.73). Compared with Hispanic adults, non-Hispanic white adults (OR = 2.09; 95% CI, 1.40-3.11) and non-Hispanic Asian adults and adults of other races/ethnicities (OR =1.91; 95% CI, 1.06-3.47) were more likely to lose any hours for planned care. Consistently, those with more than a high school education were more likely to lose any hours in planned care (OR = 1.39; 95% CI, 1.06-1.83) than those with a high school education or less. Dental problems result in hours lost from work and may adversely affect a person's productivity. There is disparity in lost hours at work by race/ethnicity and dental care affordability.

The ejector expansion refrigeration cycle (EERC) is a variant of the standard vapor compression cycle in which an ejector is used to recover part of the work that would otherwise be lost in the expansion valve. In initial testing EERC performance was poor, mainly due to thermodynamic non-equilibrium conditions in the ejector motive nozzle. Modifications were made to correct this problem, and significant performance improvements were found.

In 2001, 6.3 million passengers were involved in motor vehicle crashes. This study aimed to determine the number of work days lost as a result of motor vehicle crashes and factors that influenced people's return to work. This was a retrospective, population based cohort study of occupants in motor vehicles involved in crashes from the 1993-2001 Crashworthiness Data System produced by the National Highway Traffic Safety Administration. The sample population of people aged 18-65 years included two groups: occupants who survived and were working before the crash and occupants who were injured fatally and were estimated to have been working before the crash. Multivariate linear regression was used to analyze the impact of restraint use and injury type on return to work. Overall, 30.1% of occupants of vehicles that crashed missed one or more days of work. A crash resulted in a mean 28.0 (95% confidence interval 15.8 to 40.1) days lost from work, including losses associated with fatalities. The 2.1 million working occupants of vehicles that crashed in 2001 lost a total of 60 million days of work, resulting in annual productivity losses of over $7.5 billion (2964 to 12 075). Unrestrained vehicle occupants accounted for $5.6 billion in lost productivity. Motor vehicle crashes result in large and potentially preventable productive losses that are mostly attributable to fatal injuries.

Allergic rhinitis (AR) is increasingly acknowledged as having a substantial socioeconomic impact associated with impaired work productivity, although available information remains fragmented. This systematic review summarizes recently available information to provide a quantitative estimate of the burden of AR on work productivity including lost work time (ie, absenteeism) and reduced performance while working (ie, presenteeism). A Medline search retrieved original studies from 2005 to 2015 pertaining to the impact of AR on work productivity. A pooled analysis of results was carried out with studies reporting data collected through the validated Work Productivity and Activity Impairment (WPAI) questionnaire. The search identified 19 observational surveys and 9 interventional studies. Six studies reported economic evaluations. Pooled analysis of WPAI-based studies found an estimated 3.6% (95% confidence interval [CI], 2.4; 4.8%) missed work time and 35.9% (95% CI, 29.7; 42.1%) had impairment in at-work performance due to AR. Economic evaluations indicated that indirect costs associated with lost work productivity are the principal contributor to the total AR costs and result mainly from impaired presenteeism. The severity of AR symptoms was the most consistent disease-related factor associated with a greater impact of AR on work productivity, although ocular symptoms and sleep disturbances may independently affect work productivity. Overall, the pharmacologic treatment of AR showed a beneficial effect on work productivity. This systematic review provides summary estimates of the magnitude of work productivity impairment due to AR and identifies its main determinant factors. This information may help guide both clinicians and health policy makers. Copyright © 2017 American Academy of Allergy, Asthma & Immunology. Published by Elsevier Inc. All rights reserved.
Production lost due to cervical cancer in Poland in 2012.
Dubas-Jakóbczyk, Katarzyna; Kocot, Ewa; Seweryn, Michał; Koperny, Magdalena
Poland has one of the highest cervical cancer mortality rates in Europe. It is related to the problem of late diagnosis and low attendance rate in screening programs. The objective of the study has been to assess the annual production loss due to the cervical cancer morbidity and mortality in Poland in 2012. The outcomes have been to provide comprehensive information on cervical cancer's influence on population's ability to work and its overall economic burden for the society. The study has also provided the methodological framework for disease-related production losses in Polish settings. The human capital method was used. The production losses were calculated in both monetary and quantitative terms (working days lost) due to 4 following reasons: 1) temporary disability to work, 2) permanent disability, 3) informal care, and 4) mortality. Cervical cancer resulted in approx. 702 964 working days lost in 2012 due to absence at work for both patients and care givers and a total number of 957 678 working days lost due to patients' mortality. The total value of production lost was assessed at 111.4 million euros. More than 66% of this value was attributed to women's mortality. The calculation of production lost due to cervical cancer burden provides strong evidence to support adequate health promotion and disease prevention actions. Actions promoting cervical cancer screening should be intensified including workplace health promotion activities. Med Pr 2016;67(3):289-299.

Motivational Influences on Cognitive Performance in Children: Focus Over Fita
Worthy, Darrell A.; Brez, Caitlin C.; Markman, Arthur B.; Maddox, W. Todd
2010-01-01
Cognitive psychologists have begun to address how motivational factors influence adults’ performance on cognitive tasks. However, little research has examined how different motivational factors interact with one another to affect behavior across the lifespan. The current study examined how children perform on a classification task when placed in a regulatory fit or mismatch. Nine-year-old children performed a classification task in which they either gained or lost points for each response. Additionally, children were given either a global promotion focus (trying to earn a gift card) or a prevention focus (trying to avoid losing a gift card). Previous work indicates that adults in this task tend to perform better when there is a match (or fit) between the overall incentive to earn or avoid losing the incentive and the task reward structure to maximize points gained or minimize points lost. Unlike adults, nine-year-olds perform better in the promotion condition than in the prevention condition regardless of task reward structure. Possible explanations for the differences between adults’ and children’s performance are discussed as well as possible applications for academic settings. PMID:21552510

Job rotation is an organisational strategy widely used on assembly lines in manufacturing industries to mitigate workers' exposure so as to prevent musculoskeletal disorders. This study aimed to evaluate the effectiveness of job rotation for reducing working hours lost due to sick leave resulting from musculoskeletal diseases. The design consisted of a 1-year cluster randomised controlled trial with a blinded assessor. Production sectors of the textile industry were randomised to intervention and control groups. Both groups received ergonomic training. The intervention group performed a job rotation programme. The primary outcome measure was number of working hours lost due to sick leave as a result of musculoskeletal disease (ICD-10). The secondary outcome measures were musculoskeletal symptoms (Yes/No), risk factors for musculoskeletal diseases (0-10), psychosocial factors and fatigue (0-100), general health (0-100), and productivity (0-10). All secondary outcomes were measured at baseline and 12-month follow-up. At the 12-month follow-up, both groups showed an increase in the number of working hours lost due to sick leave for musculoskeletal disease. There was no significant difference between the job rotation intervention group (mean deviation -5.6 hours, 95% CI -25.0 to 13.8) at the 12-month follow-up and the control group. There were no significant differences between groups for the secondary outcomes (p>0.05). The job rotation programme was not effective in reducing the number of working hours lost due to sick leave, decreasing the prevalence of musculoskeletal symptoms, or improving perception of musculoskeletal pain and workplace risk factors, psychosocial risk factors and productivity.

Characterizing and Mitigating Work Time Inflation in Task Parallel Programs
Olivier, Stephen L.; de Supinski, Bronis R.; Schulz, Martin; ...
2013-01-01
Task parallelism raises the level of abstraction in shared memory parallel programming to simplify the development of complex applications. However, task parallel applications can exhibit poor performance due to thread idleness, scheduling overheads, and work time inflation – additional time spent by threads in a multithreaded computation beyond the time required to perform the same work in a sequential computation. We identify the contributions of each factor to lost efficiency in various task parallel OpenMP applications and diagnose the causes of work time inflation in those applications. Increased data access latency can cause significant work time inflation in NUMA systems.more » Our locality framework for task parallel OpenMP programs mitigates this cause of work time inflation. Our extensions to the Qthreads library demonstrate that locality-aware scheduling can improve performance up to 3X compared to the Intel OpenMP task scheduler.« less

BackgroundExposure to whole-body vibration (WBV) is a well-known risk factor for the occurrence of low-back pain (LBP). Little is known about the long-term course of back pain in workers exposed to WBV and the consequences for (temporary) disability, due to lack of cohort studies with sufficiently long follow-up periods. MethodsA systematic review of the literature was performed to assess associations between exposure to WBV and LBP, sickness absence due to low-back disorders and permanent disability. A meta-analysis was used to estimate the prevalences of LBP and sickness absence due to low-back disorders in occupational populations, depending on relevant exposure characteristics. These prevalences were converted into probabilities for transitions between no complaints, LBP, sickness due to LBP, and disability. A Markov model was applied to evaluate a hypothetical cohort of workers without LBP at the start of the cohort and a follow-up of 40 years (40 cycles of 1 year) to reflect a long-life career with continuous exposure to WBV. ResultsIn this hypothetical cohort it was estimated that among workers with the highest exposure to WBV on average about 47 weeks of their working life were lost due to sick leave because of LBP, which is approximately 2.5% of their working life. When all workers on prolonged sick leave for 52 weeks would remain disabled for the rest of their working life, a maximum of 23.4% of their working life could be lost due to high WBV exposure. Among workers without or low exposure to WBV the corresponding losses were 0.8% and 7.8%, respectively. ConclusionThe approach to assess years of work lost due to an occupational exposure may provide a more adequate description for stakeholders than the traditional measures of relative risk or attributable risk fraction. The concept of work years lost may also facilitate a better appreciation of the potential benefits of preventive measures.

To estimate productivity losses due to absenteeism and presenteeism and their determinants in patients with depression from five Colombian cities. We used data from a multicenter, mixed-methods study of adult patients diagnosed with major depressive disorder or double depression (major depressive disorder plus dysthymia) during 2010. The World Health Organization's Health and Work Performance Questionnaire was used to assess absenteeism and presenteeism. We explored the determinants of productivity losses using a two-part model. We also used a costing model to calculate the corresponding monetary losses. We analyzed data from 107 patients employed in the last 4 weeks. Absenteeism was reported by 70% of patients; presenteeism was reported by all but one. Half of the patients reported a level of performance at work at least 50% below usual. Average number of hours per month lost to absenteeism and presenteeism was 43 and 51, respectively. The probability of any absenteeism was 17 percentage points lower in patients rating their mental health favorably compared with those rating it poorly (standard error [SE] 0.09; P < 0.10) and 19 percentage points higher in patients with at least one comorbidity compared with patients with none (SE 0.10; P < 0.10). All other covariates showed no significant associations on hours lost to absenteeism. Patients with favorable mental health self-ratings had 16.4 fewer hours per month of presenteeism compared with those with poor self-ratings (SE 4.52; P < 0.01). The 2015 monetary value of productivity losses amounted to US $840 million. This study in a middle-income country confirms the high economic burden of depression. Health policies and workplace interventions ensuring adequate diagnosis and treatment of depression are recommended. Copyright © 2017. Published by Elsevier Inc.

Six pairs of Mashona oxen ploughed dry, red clay soils in August (winter) and in mid-November (spring). Between September and November the oxen were randomly assigned to 3 feeding groups: no supplement (control), 400 g/head per day of cobsheath-groundnut stover for 70 days and 800 g/head per day of the same supplement for 35 days. Cobsheath-groundnut stover was fed in order to determine its potential as supplementary feed for draught oxen during the dry season. The liveweight (LW) lost by heavy oxen during winter ploughing was lower (P < 0.001) than that of light oxen. During spring ploughing heavy oxen again lost less (P < 0.001) LW than light ones. In addition, non-supplemented oxen lost more LW than those supplemented. Therefore feeding strategies for Mashona draught oxen should aim at providing adequate nutrients to at least maintain LW during the dry season. Heavy oxen outperformed (P < 0.001) light ones during winter ploughing. Work output of supplemented oxen in spring was also significantly greater (P < 0.05) than that of non-supplemented ones. This result demonstrated the benefits of supplementary feed during the dry season. Concentrations of lactate and free fatty acids in plasma, heart rates and rectal temperatures increased (P < 0.05) markedly during work. The increases were higher (P < 0.05) for light oxen, particularly those not fed supplement.
Stress ratio effects in fatigue of lost foam cast aluminum alloy 356
NASA Astrophysics Data System (ADS)
Palmer, David E.
Lost foam casting is a highly versatile metalcasting process that offers significant benefits in terms of design flexibility, energy consumption, and environmental impact. In the present work, the fatigue behavior of lost foam cast aluminum alloy 356, in conditions T6 and T7, was investigated, under both zero and non-zero mean stress conditions, with either as-cast or machined surface finish. Scanning electron microscopy was used to identify and measure the defect from which fatigue fracture initiated. Based on the results, the applicability of nine different fatigue mean stress equations was compared. The widely-used Goodman equation was found to be highly non-conservative, while the Stulen, Topper-Sandor, and Walker equations performed reasonably well. Each of these three equations includes a material-dependent term for stress ratio sensitivity. The stress ratio sensitivity was found to be affected by heat treatment, with the T6 condition having greater sensitivity than the T7 condition. The surface condition (as-cast vs. machined) did not significantly affect the stress ratio sensitivity. The fatigue life of as-cast specimens was found to be approximately 60--70% lower than that of machined specimens at the same equivalent stress. This reduction could not be attributed to pore size alone, and is suspected to be due to the greater concentration of pyrolysis products at the as-cast surface. Directions for future work, including improved testing methods and some possible methods of improving the properties of lost foam castings, are discussed.

Mining is a hazardous occupation with elevated rates of lost-time injury and disability. The purpose of this study is twofold: 1) To identify the type of lost-time injuries in the mining workforce, regardless of the kind of mining and 2) To examine the antecedent factors to the occupational injury (lost-time injuries). We identified and extracted primary papers related to lost-time injuries in the mining sector by conducting a systematic search of the electronic literature in the eight health and related databases. We critically reviewed nine articles in the mining sector that examined lost-time injuries. Musculoskeletal injuries (hand, back, limbs, fractures, lacerations and muscle contusions), slips and falls were identified as types of lost-time injuries. The review identified the following antecedent factors related to lost-time injuries: the mining work environment (underground mining), being male, age, working with mining equipment, organizational size, falling objects, disease status, job training and lack of occupational safety management teams, recovery time, social supports, access to health services, pre-injury health status and susceptibility to injury. The mining sector is a hazardous environment that increases workers' susceptibility to occupational injuries. There is a need to create and implement monitoring systems of lost-time injuries to implement prevention programs.

Background Clinical trials in chronic pain often collect information about interference with work as answers to component questions of commonly used questionnaires but these data are not normally analysed separately. Methods We performed a meta-analysis of individual patient data from four large trials of pregabalin for fibromyalgia lasting 8-14 weeks. We analysed data on interference with work, inferred from answers to component questions of Fibromyalgia Impact Questionnaire (FIQ), Short Form 36 Health Survey, Sheehan Disability Scale, and Multidimensional Assessment of Fatigue, including "How many days in the past week did you miss work, including housework, because of fibromyalgia?" from FIQ. Analyses were performed according to randomised treatment group (pregabalin 150-600 mg daily or placebo), pain improvement (0-10 numerical pain rating scale scores at trial beginning vs. end), and end of trial pain state (100 mm visual analogue pain scale [VAS]). Results Comparing treatment group average outcomes revealed modest improvement over the duration of the trials, more so with active treatment than with placebo. For the 'work missed' question from FIQ the change for patients on placebo was from 2.2 (standard deviation [SD] 2.3) days of work lost per week at trial beginning to 1.9 (SD 2.1) days lost at trial end (p < 0.01). For patients on 600 mg pregabalin the change was from 2.1 (SD 2.2) days to 1.6 (SD 2.0) days (p < 0.001). However, the change in days of work lost was substantial in patients with a good pain response: from 2.0 (SD 2.2) days to 0.97 (SD 1.6) days (p < 0.0001) for those experiencing >/= 50% pain improvement and from 1.9 (SD 2.2) days to 0.73 (SD 1.4) days (p < 0.0001) for those achieving a low level of pain at trial end (<30 mm on the VAS). Patients achieving both >/= 50% pain improvement and a pain score <30 mm on the VAS had the largest improvement, from 2.0 (SD 2.2) days to 0.60 (SD 1.3) days (p < 0.0001). Analysing answers to the other questions yielded qualitatively similar results. Conclusions Effective pain treatment goes along with benefit regarding work. A reduction in time off work >1 day per week can be achieved in patients with good pain responses. PMID:21639874

Clinical trials in chronic pain often collect information about interference with work as answers to component questions of commonly used questionnaires but these data are not normally analysed separately. We performed a meta-analysis of individual patient data from four large trials of pregabalin for fibromyalgia lasting 8-14 weeks. We analysed data on interference with work, inferred from answers to component questions of Fibromyalgia Impact Questionnaire (FIQ), Short Form 36 Health Survey, Sheehan Disability Scale, and Multidimensional Assessment of Fatigue, including "How many days in the past week did you miss work, including housework, because of fibromyalgia?" from FIQ.

Abstract—Three types of systems dominate the current High Performance Computing landscape: the Cray XE6, the IBM Blue Gene, and commodity clusters using InfiniBand. These systems have quite different characteristics making the choice for a particular deployment difficult. The XE6 uses Cray’s proprietary Gemini 3-D torus interconnect with two nodes at each network endpoint. The latest IBM Blue Gene/Q uses a single socket integrating processor and communication in a 5-D torus network. InfiniBand provides the flexibility of using nodes from many vendors connected in many possible topologies. The performance characteristics of each vary vastly along with their utilization model. In thismore » work we compare the performance of these three systems using a combination of micro-benchmarks and a set of production applications. In particular we discuss the causes of variability in performance across the systems and also quantify where performance is lost using a combination of measurements and models. Our results show that significant performance can be lost in normal production operation of the Cray XT6 and InfiniBand Clusters in comparison to Blue Gene/Q.« less

We present here a performance analysis of three of current architectures that have become commonplace in the High Performance Computing world. Blue Gene/Q is the third generation of systems from IBM that use modestly performing cores but at large-scale in order to achieve high performance. The XE6 is the latest in a long line of Cray systems that use a 3-D topology but the first to use its Gemini interconnection network. InfiniBand provides the flexibility of using compute nodes from many vendors that can be connected in many possible topologies. The performance characteristics of each vary vastly, and the waymore » in which nodes are allocated in each type of system can significantly impact on achieved performance. In this work we compare these three systems using a combination of micro-benchmarks and a set of production applications. In addition we also examine the differences in performance variability observed on each system and quantify the lost performance using a combination of both empirical measurements and performance models. Our results show that significant performance can be lost in normal production operation of the Cray XE6 and InfiniBand Clusters in comparison to Blue Gene/Q.« less
The economics of telerehabilitation.
Dhurjaty, Sreeram
2004-01-01
This paper is an analysis of the economics of physical telerehabilitation, at home, in the clinic, and at work. This study was a precursor to generating a business case for manufacturing telerehabilitation systems. Pilot studies were performed and structured interviews conducted with providers, payers, patients, and employers. The data obtained were analyzed, in conjunction with published data, to understand the economics with respect to parameters such as lost opportunity costs at work, faster rehabilitation, and cost savings to patients, providers, payers, and employers. The results showed that telerehabilitation has a positive business case with respect to all the stakeholders. The ability to quantify and analyze data from patients remotely is convenient and economical to providers. Patients benefit by getting back to their normal activities faster, both at home as well as work. Telerehabilitation at work allows employees to be treated at work without having to take time to go to a clinic. Lost opportunity costs for employers are minimized when workers return to work faster and are treated onsite. The ability to measure progress quantitatively is beneficial for patients, providers, payers, and employers. Additionally, malingering can be detected and eradicated using telerehabilitation. Proper application of appropriate telerehabilitation technologies makes eminent economical sense. There is a strong business case for the application of telerehabilitation, onsite, in large corporations and therefore is profitable to medical device manufacturers.

Absenteeism rates are the cornerstone metrics guiding corporate policy for health care investment in employees. However, traditional absenteeism measures do not reflect the contemporary workplace milieu. It is accepted practice that employees work evenings or weekends to makeup time. Using a hours-based absenteeism measure, that accounts for time made-up as well as time lost, this paper evaluates the impact of psychological distress on employee absenteeism.Psychological distress and absenteeism data were collected from 54,264 full-time employees. Consistent with traditional approaches, employees indicated how many days they were absent. Hours based absenteeism was formulated from the ratio of how many hours the employees worked and how many hours were they expected to work in the past seven-days.Concordant with previous concinnous evidence, traditional absenteeism computation indicated that elevated psychological distress is associated with increasing absenteeism. Using the hours-based method psychological distress did not significantly influence absenteeism.Traditional calculations of absenteeism do not reflect the current work practices of the majority of employees. Employees with psychological distress may take time off work but it appears that they make up for lost time possibly to stay up to speed with task driven occupations and avoid performance review.

The aim of this study is to determine the risk and predictive factors for work disability in patients with SLE. A cross-sectional questionnaire study was performed to evaluate the employment status of a sample of consecutive Chinese patients with SLE. Demographic, socioeconomic data (age, gender, marital status, years of education and household income), employment status, self-reported fatigue score and disease characteristics (SLE duration, organ damage and disease activity) were collected. Work disability was defined by the failure to work due to SLE. The cumulative incidence of work disability since the time of SLE diagnosis was studied by a Kaplan Meier's plot, and factors predictive of work disability were studied by Cox regression. A total of 147 patients with SLE were studied (mean age = 39.4 +/- 11.3 years; 95% women). Among 105 patients who were working at the time of SLE diagnosis, 39 (37%) lost their ability to work as a result of SLE after a mean disease duration of 10.0 +/- 6.1 years. Twenty-two (56%) patients lost their work ability within 2 years of diagnosis of SLE. The self-reported reasons for job loss were musculoskeletal pain (87%), skin disease (26%), renal problem (21%), fatigue (85%), memory deterioration (51%), anxiety or depressive symptoms (74%), too frequent sick leave (10%) and long-term hospitalisation (10%). The cumulative risk of work disability was 36% at 5 years after SLE diagnosis. In a Cox regression model, age (HR = 1.06 [1.02-1.11] per year; P = 0.008), self-reported fatigue score (HR = 1.06 [1.01-1.10] per point; P = 0.01) and mean disease activity score in the preceding two years (HR = 1.20 [1.02-1.42] per point; P = 0.03) were independently associated with working disability. In all, 37% of this group of patients with SLE lost their work ability after having the disease for 10 years. More than 50% of these patients developed work disability within the first 2 years of SLE diagnosis. Older age, fatigue and more active disease were independent predictors of work disability.

Injuries from electric saws cause considerable hand trauma. This study is designed to provide information detailing the costs of these injuries. The study was performed in a tertiary referral academic medical center. The records of patients injured by electric table saws were reviewed. Information regarding demographics, injury severity, medical expense, and time lost from work was analyzed. The patients were stratified by injury severity for further analysis. The mean wage for the region was used to estimate costs of time away from work. The Consumer Protection Agency's review was used to estimate the nationwide burden of these injuries. The study group included 134 patients. Of these patients, 126 were male and 8 were female. The dominant hand was injured in 20; the nondominant, in 114. The mean age was 47.0 years. The mean time lost from work was 64 days. The mean cost of medical expenses for all patients was $22,086, with $8,668 in lost wages, for a total of $30,754 mean cost per injury. The total economic burden for the injuries in this study is $4,121,097. These injuries represent a spectrum of severity, with minor injuries incurring lower hospital fees and requiring less time off work as compared to more involved injuries. Electric saws cause a wide spectrum of injuries that result in not only tremendous physical and emotional pain but also substantial economic impact as well. Technologies that would prevent such injuries would be a socioeconomic advancement. Federal mandates to implement such technologies should be encouraged.
Examining job tenure and lost-time claim rates in Ontario, Canada, over a 10-year period, 1999-2008.

We sought to examine the association between job tenure and lost-time claim rates over a 10-year period in Ontario, Canada. Data were obtained from workers' compensation records and labour force survey data from 1999 to 2008. Claim rates were calculated for gender, age, industry, occupation, year and job tenure group. A multivariate analysis and examination of effect modification were performed. Differences in injury event and source of injury were also examined by job tenure. Lost-time claim rates were significantly higher for workers with shorter job tenure, regardless of other factors. Claim rates for new workers differed by gender, age and industry, but remained relatively constant at an elevated rate over the observed time period. This study is the first to examine lost-time claim rates by job tenure over a time period during which overall claim rates generally declined. Claim rates did not show a convergence by job tenure. Findings highlight that new workers are still at elevated risk, and suggest the need for improved training, reducing exposures among new workers, promoting permanent employment, and monitoring work injury trends and risk factors.

This analysis of Commonwealth Fund survey data estimates the economic impact of health problems on worker productivity. In 2003, an estimated 18 million adults ages 19 to 64 were not working and had a disability or chronic disease, or were not working because of health reasons. Sixty-nine million workers reported missing days due to illness, for a total of 407 million days of lost time at work. Fifty-five million workers reported a time when they were unable to concentrate at work because of their own illness or that of a family member, accounting for another 478 million days. Together, labor time lost due to health reasons represents lost economic output totaling $260 billion per year. Workers without paid time off to see a physician are more likely to report missing work or being unable to concentrate at their job.

Work-related factors are one of the known risk factors for depression. Given that the ability to work is considered an important aspect of well-being and health status, we investigated the association between the loss of work ability and depression. We further examined the association stratified by employment status. We used data from the Korea Welfare Panel Study. The dependent variable of the present study was depression, which is measured by the Center for Epidemiologic Studies Depression Scale. Work ability transition from the previous year was divided into three categories: maintained, loss, and complete loss. A linear mixed-effects model was performed for the analysis. The work ability loss group (β = 2.071, p < 0.0002) and the work ability completely loss group (β = 2.651, p = 0.015) had higher depression scores compared to those who maintained their work ability from the previous year. Specifically, those who lost their work ability and their job (β = 3.685, p = 0.0068) had the highest depression scores compared to those who maintained their work ability and job. We found that those who lost their ability to work may be at risk of depression, and this finding was particularly prominent among those who also became unemployed. Therefore, psychological support is needed for these individuals to overcome the negative influence of the loss of work ability.

Working at the Weekend: Fathers' Time with Family in the United Kingdom.
Hook, Jennifer L
2012-08-01
Whereas most resident fathers are able to spend more time with their children on weekends than on weekdays, many fathers work on the weekends spending less time with their children on these days. There are conflicting findings about whether fathers are able to make up for lost weekend time on weekdays. Using unique features of the United Kingdom's National Survey of Time Use 2000 (UKTUS) I examine the impact of fathers' weekend work on the time fathers spend with their children, family, and partners (N = 595 fathers). I find that weekend work is common among fathers and is associated with less time with children, families, and partners. Fathers do not recover lost time with children on weekdays, largely because weekend work is a symptom of overwork. Findings also reveal that even if fathers had compensatory time, they are unlikely to recover lost time spent as a family or couple.

Dengue is a serious public health problem with an important economic impact. This study used data from a cluster randomised controlled trial of community mobilisation for dengue prevention to estimate the household costs of treatment of dengue illness. It examined the economic impact of the trial intervention in the three coastal regions of Mexico's Guerrero State. The 2010 baseline survey covered households in a random sample of 90 clusters in the coastal regions; the clusters were randomly allocated to intervention or control and re-surveyed in 2012. The surveys asked about dengue cases in the last 12 months, expenditures on their treatment, and work or school days lost by patients and care givers. We did not assign monetary value to days lost, since a lost day to a person of low earning power is of equal or higher value to that person than to one who earns more. The 12,312 households in 2010 reported 1020 dengue cases in the last 12 months (1.9% of the sample population). Most (78%) were ambulatory cases, with a mean cost of USD 51 and 10.8 work/school days, rising to USD 96 and 11.4 work/school days if treated by a private physician. Hospitalised cases cost USD 28-94 in government institutions and USD 392 in private hospitals (excluding additional inpatient charges), as well as 9.6-17.3 work/school days. Dengue cases cost households an estimated 412,825 work/school days throughout the three coastal regions. In the follow up survey, 6.1% (326/5349) of households in intervention clusters and 7.9% (405/5139) in control clusters reported at least one dengue case. The mean of days lost per case was similar in intervention and control clusters, but the number of days lost from dengue and all elements of costs for dengue cases per 1000 population were lower in intervention clusters. If the total population of the three coastal regions had received the intervention, some 149,401 work or school days lost per year could have been prevented. The economic effect of dengue on households, including lost work days, is substantial. The Camino Verde trial intervention reduced household costs for treatment of dengue cases. The trial was registered as ISRCTN:27,581,154 .

This project explores the costs of cleft lip and/or palate surgeries in Palestine and Sudan, two low- and middle-income countries (LMIC), in the Middle East. Our purpose is to examine the veracity of advertisements from international cleft organizations claiming that "250 US dollars (USD) covers the cost of a single cleft surgery." We hypothesize that the actual cost of surgery is greater than 250 USD. Costs for each cleft surgery were organized broadly into 5 categories: hospital charges, personnel (time and money spent for health professionals to travel to LMIC, including lost wages), tests, consumables, and reusables. Each item was priced at market value during the time of data collection. Following itemization of actual costs, we compared the costs per cleft surgery among four surgical practice models: (1) visiting international surgical teams, (2) visiting international surgeon working with local teams, (3) local teams working at government hospitals, and (4) local teams working at private hospitals. Our results suggest that 250 USD is an underestimate of actual costs per cleft surgery in all models. The most expensive model in both Palestine and Sudan was the first model, visiting international teams performing all team functions; the cheapest surgical model in both countries was a local team working at government hospitals. The largest cost for any of these models is travel and lost wages for international team members. Eliminating this single cost (travel) decreases overall cost tremendously, but still does not approach the advertised cost of 250 USD. We conclude that 250 USD underestimates the actual costs to perform a single cleft surgery in Palestine and Sudan. If international cleft organizations are genuinely committed to creating sustainable international cleft programs, they should focus exclusively on training local professionals to perform surgery in hospitals of their own choosing.
Different approaches to valuing the lost productivity of patients with migraine.

To calculate and compare the human capital approach (HCA) and friction cost approach (FCA) methods for estimating the cost of lost productivity of migraineurs after the initiation of sumatriptan from a US societal perspective. Secondary, retrospective analysis to a prospective observational study. A mixed-model managed care organisation in western Pennsylvania, USA. Patients with migraine using sumatriptan therapy. Patient-reported questionnaires collected at baseline, 3 and 6 months after initiation of sumatriptan therapy. The cost of lost productivity estimated with the HCA and FCA methods. Of the 178 patients who completed the study, 51% were full-time employees, 13% were part-time, 18% were not working and 17% changed work status. Twenty-four percent reported a clerical or administrative position. From the HCA, the estimated total cost of lost productivity for 6 months following the initiation of sumatriptan was $US117905 (1996 values). From the FCA, the six-month estimated total cost of lost productivity ranged from $US28329 to $US117905 (1996 values). This was the first study to retrospectively estimate lost productivity of patients with migraine using the FCA methodology. Our results demonstrate that depending on the assumptions and illustrations employed, the FCA can yield lost productivity estimates that vary greatly as a percentage of the HCA estimate. Prospective investigations are needed to better determine the components and the nature of the lost productivity for chronic episodic diseases such as migraine headache.
Can increasing adult vaccination rates reduce lost time and increase productivity?
Rittle, Chad
2014-12-01
This article addresses limited vaccination coverage by providing an overview of the epidemiology of influenza, pertussis, and pneumonia, and the impact these diseases have on work attendance for the worker, the worker's family, and employer profit. Studies focused on the cost of vaccination programs, lost work time, lost employee productivity and acute disease treatment are discussed, as well as strategies for increasing vaccination coverage to reduce overall health care costs for employers. Communicating the benefits of universal vaccination for employees and their families and combating vaccine misinformation among employees are outlined. Copyright 2014, SLACK Incorporated.
Pressing back: Split Britches' Lost Lounge and the retro performativity of lesbian performance.
Eschen, Nicole
2013-01-01
Using theories of affect and queer temporality, this article examines Split Britches' Lost Lounge as lesbian resistance to the pressures to remember or forget the past, condemn or embrace the future. In this piece, butch-femme duo Peggy Shaw and Lois Weaver develop a retro performativity that pushes back against systems that strive to make lesbianism invisible, private, and apolitical. Through performances that resignify past pop culture artifacts, particularly the duo of Louis Prima and Keely Smith, Shaw and Weaver perform a past that is simultaneously lost and embodied, pressuring the audience to reconsider notions of progress and beauty.
When worlds collide: elder caregiving poses new challenges for balancing work and life.
Rachor, M M
1998-09-01
Nearly one in four U.S. households (an estimated 22.4 million) are caring for elderly family members or friends; as the nation's population ages, more and more workers will take on elder caregiving responsibilities. As this trend continues, employers will face increasing concerns about lost productivity and many employees will struggle to balance the demands of work and caregiving responsibilities. To help resolve the situation, many employers may look to a comprehensive work/life program, which incorporates an intensive focus on elder-care issues, to help boost morale, improve employee productivity and job performance, and reduce stress and absenteeism associated with caregiving.

Chronic rhinosinusitis (CRS) is associated with significant losses of patient productivity that cost billions of dollars every year. The causative factors for decreases in productivity in patients with CRS have yet to be determined. To determine which patterns of CRS symptoms drive lost productivity. Prospective, cross-sectional cohort study of 107 patients with CRS. Sinonasal symptom severity was measured using the 22-item Sinonasal Outcomes Test, from which sleep, nasal, otologic or facial pain, and emotional function subdomain scores were calculated using principal component analysis. Depression risk was assessed with the 2-item Patient Health Questionnaire (PHQ-2), whereas nasal obstruction was assessed with the Nasal Obstruction Symptom Evaluation (NOSE) instrument. Lost productivity was assessed by asking participants how many days of work and/or school they missed in the last 3 months because of CRS. Associations were sought between lost productivity and CRS symptoms. A total of 107 patients were recruited. Patients missed a mean (SD) of 3.1 (12.9) days of work or school because of CRS. Lost productivity was most strongly associated with the emotional function subdomain (β = 7.48; 95% confidence interval [CI], 5.71-9.25; P < .001). Reinforcing this finding, lost productivity was associated with PHQ-2 score (β = 4.72; 95% CI, 2.62-6.83; P < .001). Lost productivity was less strongly associated with the nasal symptom subdomain score (β = 2.65; 95% CI, 0.77-4.52; P = .007), and there was no association between lost productivity and NOSE score (β = 0.01; 95% CI, -0.12 to 0.13; P = .91). Symptoms associated with depression are most strongly associated with missed days of work or school because of CRS. Further treatment focusing on depression-associated symptoms in patients with CRS may reduce losses in productivity. Copyright © 2016 American College of Allergy, Asthma & Immunology.

Predictors of lost time from work among nursing personnel who sought treatment for back pain.
Pompeii, Lisa A; Lipscomb, Hester J; Dement, John M
2010-01-01
To examine possible predictors of lost workdays among nurses and nurses' aides who sought treatment for work-related back pain. Nursing staff employed at a tertiary care medical center over a 13-year time period (1994 through 2006). We used existing data from clinic surveys administered to nursing personnel during their initial treatment visit to the hospital's occupational health clinic. Predictors of losing ≤ 7 and ≥ 8 workdays was examined. 589 of 708 (83%) nursing personnel with complaints of work-related back pain completed the survey, with 31% resulting in lost workdays. Experiencing sudden onset of pain (RR:1.9; 95% CI: 1.1, 3.1), a combination of severe pain with numbness and tingling in the back/legs (RR: 7.4; 95% CI: 2.9, 18.6), severe pain only (RR: 4.4; 95% CI: 1.8, 11.1), numbness and tingling in the back/legs only (RR: 3.5; 95% CI: 1.0, 12.2), and working < 5 years at the hospital (RR: 2.3; 95% CI: 1.2, 4.7) were predictive of losing ≥ 8 workdays. Job title, work demands, work conflicts, and most psychosocial factors were not predictive. Severe pain, neurologic symptoms and sudden onset of pain were predictive of delayed return-to-work; however, these symptoms alone should not be considered indicators of poor outcomes given that most workers who reported these symptoms returned to work in less than 8~days. Among these health care workers, lost workdays appear to be related to more severe pathology rather than workplace characteristics.
Unpaid work in health economic evaluations.
Krol, Marieke; Brouwer, Werner
2015-11-01
Given its societal importance, unpaid work should be included in economic evaluations of health care technology aiming to take a societal perspective. However, in practice this does not often appear to be the case. This paper provides an overview of the current place of unpaid work in economic evaluations in theory and in practice. It does so first by summarizing recommendations regarding the inclusion of unpaid labor reported in health economic textbooks and national guidelines for economic evaluations. In total, three prominent health economic text-books were studied and 28 national health economic guidelines. The paper, moreover, provides an overview of the instruments available to measure lost unpaid labor and reports on a review of the place of unpaid labor in applied economic evaluations in the area of rheumatoid arthritis. The review was conducted by examining methodology of evaluations published between 1 March 2008 and 1 March 2013. The results of this study show that little guidance is offered regarding the inclusion of unpaid labor in economic evaluations in textbooks and guidelines. The review identified five productivity costs instruments including questions about unpaid work and 33 economic evaluations of treatments for rheumatoid arthritis of which only one included unpaid work. The results indicate that unpaid work is rarely included in applied economic evaluations of treatments for rheumatoid arthritis, despite this disease expecting to be associated with lost unpaid work. Given the strong effects of certain diseases and treatments on the ability to perform unpaid work, unpaid work currently receives less attention in economic evaluations than it deserves.

Cohort study. To measure the prevalence and incidence of work absenteeism involving neck pain in a cohort of claimants to the Ontario Workplace Safety & Insurance Board (WSIB). According to workers' compensation statistics, neck pain accounts for a small proportion of lost-time claims. However, these statistics may be biased by an underenumeration of claimants with neck disorders. We studied all lost-time claimants to the Ontario WSIB in 1998 and used 2 methods to enumerate neck pain cases. We report the prevalence and incidence of neck pain using 2 denominators: (1) annual number of lost-time claimants and (2) an estimate of the Ontario working population covered by the WSIB. The estimated percentage of lost-time claimants with neck pain ranged from 2.8% (95% CI 2.5-3.3) using only codes specific for neck pain to 11.3% (95% CI 9.5-13.1) using a weighted estimate of codes capturing neck pain cases. The health care sector had the highest percentage of claims with neck pain. The annual incidence of neck pain among the Ontario working population ranged from 6 per 10,000 full-time equivalents (FTE) (95% CI 5-6) to 23 per 10,000 FTE (95% CI 20-27) depending on the codes used to capture neck pain. Male workers between the ages of 20 and 39 years were the most likely to experience an episode of work absenteeism involving neck pain. Neck pain is a common and burdensome problem for Ontario workers. Our study highlights the importance of properly capturing all neck pain cases when describing its prevalence and incidence.

Cohort study. To describe the course of lost-time claims involving neck pain in workers compensated by the Ontario Workplace Safety and Insurance Board (WSIB). The prevalence of neck pain in workers varies from 27.1% to 47.8%. Very little is known about the course of work absenteeism related to neck pain. Our cohort included 5761 injured workers with an incident lost-time claim to the WSIB in 1997 and 1998. Claimants were followed for 2 years. We measured the cumulative time on lost-time benefits using the Kaplan-Meier method and described the number and duration of episodes on benefits. The median cumulative time-on-benefits for the cohort was 13 days (95% CI: 13-14). The cumulative time on benefits was shorter for men than women and for younger than older workers. 14.2% of claimants experienced multiple episodes of work absenteeism during the 2 years after the initial claim. The median time on benefits for claimants with a single episode was 11 days (95% CI: 10-11). The median length of the first episode on benefits was longer for claimants with multiple episodes (19-22 days) compared with those with a single episode (11 days). Age was positively associated with longer time-on-benefits in claimants with a single episode of work absenteeism. Most injured workers who make a workers' compensation claim that involves neck pain do not make a second claim in the subsequent 2 years. However, an important minority (14.2%) experience multiple episodes of work absenteeism and these workers accrue 40.4% of all lost-time days. Recurrent claims involving neck pain represent a significant burden of disability in Ontario.
Lost Souls? The Demoralization of Academic Labour in the Measured University

2017-01-01
In this conceptual paper, I contend that the soul of academic labour is becoming lost in performativity. Performativity, I explain, is a form of regulation and control that deploys technical rationality and judgements to incentivize and punish academics. Indeed, performativity is central to the culture of measurement within contemporary…

Hand sanitizer and rates of acute illness in military aviation personnel.
Van Camp, Roscoe O; Ortega, Hernando J
2007-02-01
Alcohol-based hand sanitizer (HS) kills most organisms that cause acute illness, an important cause of lost duty time among aviation personnel. This preliminary study observed the impact on the acute illness rate when HS was made readily accessible to pilots. Wall-mounted HS dispensers were placed in two fighter squadron operations buildings during November 2005 and various media were used to alert all base personnel to the importance of hand hygiene and cough hygiene. Data were obtained for two groups of personnel on the same base: 1) pilots who worked in the two HS-equipped buildings (Squadron) (n = 56); and 2) pilots and air traffic controllers who worked at other locations (Non-Squadron) (n = 61). The incidence of acute illness and the cumulative number of duty days lost was determined in each group for the winters of 2004-05 (no HS) and 2005-06 (HS available). For the Squadron group, the acute illness rates were 2.4% in 2004-5 (210 duty days lost) (no HS) compared with 0.9% in 2005-6 (78 duty days lost) when HS was provided. No year-to-year difference was apparent for the Non-Squadron group, where the illness rates were 2.4% in 2004-5 (229 duty days lost) and 2.3% in 2005-6 (221 duty days lost). Making HS readily available at locations frequented by pilots together with educating them regarding hand hygiene may reduce the occurrence of acute illness and number of duty days lost.

The reproductive performance of 46 cows in a semi-arid, smallholder farming area of Zimbabwe was monitored for a year. Half the cows were used throughout the monitoring period for various draught purposes, including ploughing and procurement of farm produce for marketing using carts. All the cows lost body weight between July and October, after which the cows that were not worked gained weight until June of the following year. In contrast, the cows that were worked continued to lose body weight until January, throughout the time during which they were used to provide draught power, after which they gained weight. Body weights were significantly higher (p < 0.05) in non-working than in working cows in January and February. Ovarian activity was higher (p < 0.001) in non-working compared to working cows, particularly between November and February, while calving rates were also higher (p < 0.05) in non-working cows. It is concluded that using cows for draught purposes caused loss of body weight and reduced ovarian activity and conception rates.

To propose a standard measure of absenteeism (the work lost rate [WLR]) be included in future research to facilitate understanding and allow for translation of findings between scientific disciplines. Hourly payroll data derived from "punch clock" reports was used to compare various measures of absenteeism used in the literature and the application of the proposed metric (N = 4000 workers). Unpaid hours and full absent days were highly correlated with the WLR (r = 0.896 to 0.898). The highest percentage of unpaid hours (lost work time) is captured by absence spells of 1 and 2 days duration. The proposed WLR metric captures: 1) The range and distribution of the individual WLRs, 2) the percentage of subjects with no unpaid hours, and 3) the population WLR and should be included whenever payroll data is used to measure absenteeism.

To explore the association between the initial 60 days of prescriptions for psychotropic medications and final workers' compensation claim outcomes. A cohort of 11,394 claimants involved in lost time injuries between 1999 and 2002 were followed through December 31, 2009. Logistic regressions and Cox Proportional Hazard Models were used in the analysis. The initial 60 days of prescriptions for psychotropic medications were significantly associated with a final claim cost at least $100,000. Odds ratios were 1.88 for short-acting opioids, 2.14 for hypnotics, antianxiety agents, or antidepressants, and 3.91 for long-acting opioids, respectively. Significant associations were also found between decreased time lost from work and decreased claim closures during the study period. Early prescription of opioids and other psychotropic drugs may be useful predictors of high claim costs and time lost from work.

Over 60% of energy that is generated is lost as waste heat with close to 90% of this waste heat being classified as low grade being at temperatures less than 200°C. Many technologies such as thermoelectrics have been proposed as means for harvesting this lost thermal energy. Among them, that of SMA (shape memory alloy) heat engines appears to be a strong candidate for converting this low grade thermal output to useful mechanical work. Unfortunately, though proposed initially in the late 60's and the subject of significant development work in the 70's, significant technical roadblocks have existed preventing this technology from moving from a scientific curiosity to a practical reality. This paper/presentation provides an overview of the work performed on SMA heat engines under the US DOE (Department of Energy) ARPA-E (Advanced Research Projects Agency - Energy) initiative. It begins with a review of the previous art, covers the identified technical roadblocks to past advancement, presents the solution path taken to remove these roadblocks, and describes significant breakthroughs during the project. The presentation concludes with details of the functioning prototypes developed, which, being able to operate in air as well as fluids, dramatically expand the operational envelop and make significant strides towards the ultimate goal of commercial viability.

To determine which specific groups of occupational stress factors influence the duration of temporary work disability related to arterial hypertension and joint complications/co-morbidities. Workers (n = 1398; 1009 in the exposed group, 389 in the control group) with arterial hypertension who worked at one workplace for a minimum of 10 years were divided into 10 subgroups, depending on the presence of joint complications/co-morbidities. The intensity of seven groups of occupational stress factors, the total score of Occupational Stress Index (OSI) and the average number of lost working days during 1 year were analysed. The number of lost working days due to arterial hypertension and joint complications/co-morbidities was significantly higher in the exposed group. In all subgroups of the exposed group there was a high correlation between the number of lost working days and the total OSI score. Specific occupational stress factors were associated with specific complications: High Demands with chronic myocardial infarction, Strictness with cerebral haemorrhage, Conflict/Uncertainty with cerebral infarction, Extrinsic Time Pressure with acute myocardial infarction, and Avoidance/Symbolic Aversiveness with non-insulin-dependent diabetes. There are specific groups of occupational stress factors which can influence the duration of work disability associated with certain complications and co-morbidities of arterial hypertension.

Fluids from the Lost City Hydrothermal Field are rich in hydrogen and methane, with high pHs (9 - 11), as a result of serpentinization reactions at moderate temperatures of approximately 120-200°C. It has been predicted that organic carbon compounds would form abiologically under these chemical and thermal conditions from inorganic precursors, in the form of hydrocarbons and organic acids. Previous work has demonstrated the presence of high concentrations of both formate and acetate in the Lost City fluids [Lang et al., 2010, GCA]. Formate is the second most prevalent carbon species in the fluids and may provide local microbial communities with a necessary carbon source in the face of low dissolved inorganic carbon concentrations. The goals of this study are to constrain the formation mechanisms of these organic acids (abiotic vs. biotic) and to identify their inorganic precursors. Formate and acetate were isolated from multiple fluid samples by preparative high-performance liquid chromatography for isotopic analysis. The δ13C of formate is similar to that of Lost City methane, and consistent with an abiological origin. The isotopic signature of acetate is significantly different from these values, and may be indicative of a biological source. Radiocarbon measurements of the isolated formate are in progress and should allow us to determine if the precursor carbon is derived from a mantle or deep-seawater source. Alkaline hydrothermal systems have been proposed as potential sites to the origin of life and formate has been proposed as a critical intermediate towards the kinds of reduced carbon species found in biochemistry. Evidence of an abiological formation mechanism of formate at Lost City may significantly further our understanding of prebiotic chemistry.

Integration of skills into an autonomous robot that performs a complex task is described. Time constraints prevented complete integration of all the described skills. The biggest problem was tuning the sensor-based region-finding algorithm to the environment involved. Since localization depended on matching regions found with the a priori map, the robot became lost very quickly. If the low level sensing of the world is not working, then high level reasoning or map making will be unsuccessful.

To study costs and outcome for serious hand and arm injuries during the first year after the trauma. In patients with a Hand Injury Severity Score (HISS) > 50, DASH and EQ-5D scores as well as factors related to costs within the health care sector, costs due to lost production and total costs were evaluated. Cox-regression analysis stratifying for mechanism of injury was used to analyse return to work. The majority of the 45 included patients (median 42 years 16-64) were men with severe (n = 9) or major (n = 36) injuries with different type of injuries (amputations n = 13; complex injuries n = 18; major nerve injuries/full house n = 13; burn injury n = 1). DASH and EQ-5D decreased and increased, respectively, significantly over time during one year. Total costs (+34%) and costs of lost production were highest for persons injured at work. Factors associated with higher health care costs were age >50 years (+52%), injury at work (+40%) and partial labour market activity (+66%). Costs of lost production had a significant role in total costs of injury. Patients with major injuries had longer duration of sick leave. Patients with severe injuries were more likely to return to work [(RR 3.76 (95% CI 1.38-10.22) from Cox regression, controlling for age, gender and presence of nerve injury]. Despite the fact that work environments have constantly improved over the last decades, we found that hand injuries at work were most costly both in terms of health care and costs of lost production, although the severity, i.e. HISS, did not differ from injuries occurring at home or during leisure.

Content delivery network (CDN) allows internet providers to locate their services, to map their coverage into networks without necessarily to own them. CDN is part of the current internet infrastructures, supporting multi server applications especially social media. Various works have been proposed to improve CDN performances. Since accesses on social media servers tend to be short but frequent, providing redundant to the transmitted packets to ensure lost packets not degrade the information integrity may improve service performances. This paper examines the implementation of rateless code in the CDN infrastructure. The NS-2 evaluations show that rateless code is able to reduce packet loss up to 50%.
Rhinitis and its impact on work.
Vandenplas, Olivier; D'Alpaos, Vinciane; Van Brussel, Philippe
2008-04-01
Health-related work disability has been increasingly recognized as an important component of the economic and societal burden of a disease. The purpose of this review is to summarize recently published data pertaining to the impact of rhinitis on work disability. Recent studies have investigated the impact of rhinitis on both the amount of time missed from work (absenteeism) and the level of work effectiveness while on the job (presenteeism). These studies have shown that rhinitis has a rather modest effect on absenteeism, with estimated productivity losses of approximately 1-4% resulting from missed work time. By contrast, rhinitis is associated with substantial impairment in at-work performance. Estimates of lost productivity attributable to reduced on-the-job effectiveness ranged from 11 to 40%. The impact of rhinitis on work productivity is affected by symptom severity, and allergen exposure, and it can be reduced by second-generation antihistamines. The impact of rhinitis on work productivity should be further characterized and taken into account for establishing cost-effective management strategies.

Construction workers globally face disproportionate threats to health and wellbeing, constituted by the nature of the work they perform. The workplace fatalities and lost-time injuries experienced by construction workers are significantly greater than in other forms of work. This paper draws on the culture-centered approach (CCA) to dialogically articulate meanings of workplace risks and injuries, voiced by Bangladeshi migrant construction workers in Singapore. The narratives voiced by the participants suggest an ecological approach to workplace injuries in the construction industries, attending to food insecurity, lack of sleep, transportation, etc. as contextual features of work that shape the risks experienced at work. Moreover, participant voices point to the barriers in communication, lack of understanding, and experiences of incivility as features of work that constitute the ways in which they experience injury risks. The overarching discourses of productivity and efficiency constitute a broader climate of threats to worker safety and health.
The use of moderated mediated analysis to study the influence of hypo-hydration on working memory.
Young, Hayley A; Benton, David
2016-07-13
To date, dehydration has been typically reported to infl uence psychological parameters when there has been at least a 2% loss of body mass, although there has been little examination of those going about their everyday lives, those who have lost less than 1% of body mass. In such situations factors such as the initial hydration status and individual differences in the response to a reduced fl uid intake are likely to be infl uential. Yet to study the complexity added by such additional variables novel methods of statistical analysis are required. The present study describes the use of moderated mediation, an approach that asks various questions: fi rstly, is drinking infl uential?; secondly, does a mediator (e.g.,thirst) sit between an independent and dependent variable?; and thirdly, does an effect only occur under certain conditions such as initial osmolality? In the study, 118 subjects were exposed to 30 °C for four hours during which they half drank 300 ml water. The serial sevens test of working memory was performed before and at the end of the procedure. A 0.6% loss of body mass reduced the effi ciency of working memory. Those who consumed water had better working memory; working memory was worse in participants who lost more body mass or became thirstier, but only in those with higher levels of baseline osmolality. Small variations in hydration status infl uenced cognitive functioning although there were individual differences in the response. The parameters that influence an adverse response to hypo-hydration need to be established to allow giving appropriate advice.
Decrease the Number of Glovebox Glove Breaches and Failures

Los Alamos National Laboratory (LANL) is committed to the protection of the workers, public, and environment while performing work and uses gloveboxes as engineered controls to protect workers from exposure to hazardous materials while performing plutonium operations. Glovebox gloves are a weak link in the engineered controls and are a major cause of radiation contamination events which can result in potential worker exposure and localized contamination making operational areas off-limits and putting programmatic work on hold. Each day of lost opportunity at Technical Area (TA) 55, Plutonium Facility (PF) 4 is estimated at $1.36 million. Between July 2011 and Junemore » 2013, TA-55-PF-4 had 65 glovebox glove breaches and failures with an average of 2.7 per month. The glovebox work follows the five step safety process promoted at LANL with a decision diamond interjected for whether or not a glove breach or failure event occurred in the course of performing glovebox work. In the event that no glove breach or failure is detected, there is an additional decision for whether or not contamination is detected. In the event that contamination is detected, the possibility for a glove breach or failure event is revisited.« less
Stress management standards: a warning indicator for employee health.
Kazi, A; Haslam, C O
2013-07-01
Psychological stress is a major cause of lost working days in the UK. The Health & Safety Executive (HSE) has developed management standards (MS) to help organizations to assess work-related stress. To investigate the relationships between the MS indicator tool and employee health, job attitudes, work performance and environmental outcomes. The first phase involved a survey employing the MS indicator tool, General Health Questionnaire-12 (GHQ-12), job attitudes, work performance and environmental measures in a call centre from a large utility company. The second phase comprised six focus groups to investigate what employees believed contributed to their perceived stress. Three hundred and four call centre employees responded with a response rate of 85%. Significant negative correlations were found between GHQ-12 and two MS dimensions; demands (Rho = -0.211, P < 0.001) and relationships (Rho= -0.134, P < 0.05). Other dimensions showed no significant relationship with GHQ-12. Higher levels of stress were associated with reduced job performance, job motivation and increased intention to quit but low stress levels were associated with reduced job satisfaction. Lack of management support, recognition and development opportunities were identified as sources of stress. The findings support the utility of the MS as a measure of employee attitudes and performance.
Workers' compensation experience of North Carolina residential construction workers, 1986-1994.
Dement, J M; Lipscomb, H
1999-02-01
A total of 31,113 workers' compensation claims among 7,400 North Carolina Homebuilders Association (NCHA) members and their subcontractors for the period 1986-1994 were analyzed to calculate workers' compensation claim incidence density rates. For the 7 years studied, the average rate (cases/200,000 work hours) for all claims was 16.40 and the rate for medical or lost time cases was 10.78. Highest rates for cases involving medical costs or paid lost time by mechanism of injury were observed for being struck by an object (3.1), lifting/movement (1.97), falls from a different level (1.13), striking against an object (0.87), and falls on the same level (0.46). Rates by mechanism of injury were highest for muscle strains (2.34), wounds/punctures (2.33), bruises/contusions (1.24), fractures/dislocations (0.98), and injuries to the eyes (0.81). Among medical cost or lost work time cases, body parts with highest injury rates were back/shoulders (1.99), fingers (1.31), leg/knee (1.00), hand/wrist (1.00), foot/ankle (0.86), and eyes (0.82). Injury rates were found to vary substantially among the residential construction trades. For more serious injuries involving medical costs greater than $2,000 or any lost work time, rates were highest for welders and cutters (28.1), insulators (24.3), roofers (19.4), and carpenters (15.3). The same general trends by trade were observed for cases involving paid lost time except that roofers were highest, with a rate of 9.1, followed by insulators (8.5), welders and cutters (5.8), and carpenters (5.8). Rates of falls from a different level resulting in medical costs or lost work time were highest for roofers (5.54), insulators (3.53), carpenters (2.05), and drywall installers (1.99). Descriptive information for falls from a different level resulting in paid lost time during 1993-1994 (n = 219) were reviewed to better determine the causes and circumstances of injuries. Falls from a roof accounted for 25.4 percent of the cases followed by falls involving scaffolds (23.9%) and ladders (20.6%), and falls from ceiling joists, floor joists, or framing (14.8%). Twenty-six work-related deaths occurred with vehicle accidents (n = 6) being the major known cause of death, followed by falls (n = 3), being struck by an object (n = 3), electric shock (n = 2), and contact with energy or chemicals (n = 2). Consistent with other analyses of workers' compensation data, chronic occupational diseases are not well captured in the workers' compensation claims among home builders; therefore, a companion study has examined mortality patterns among North Carolina construction workers.
The association of health risks with on-the-job productivity.

2005-08-01
Decreased on-the-job productivity represents a large yet poorly characterized indirect cost to employers. We studied the impact of employee health risk factors on self-reported worker productivity (presenteeism). Using a brief version of the Work Limitation Questionnaire incorporated into a Health Risk Appraisal, 28,375 employees of a national company responded to the survey. The association between health risks and work limitation and each of the four domains was examined. Percentage of lost productivity also was estimated. Ten of 12 health risk factors studied were significantly associated with self-reported work limitations. The strength of the associations varied between risks and the four domains of work limitation. Perception-related risk factors such as life dissatisfaction, job dissatisfaction, poor health, and stress showed the greatest association with presenteeism. As the number of self-reported health risk factors increased, so did the percentage of employees reporting work limitations. Each additional risk factor was associated with 2.4% excess productivity reduction. Medium and high-risk individuals were 6.2% and 12.2% less productive than low-risk individuals, respectively. The annual cost of lost productivity in this corporation was estimated at between 99Mdollars and 185Mdollars or between 1392dollars and 2592dollars per employee. Health risk factors represent additional causes of lost productivity.

Asthma is associated with high indirect costs due to lower work productivity and higher absenteeism and presenteeism. To study loss of productivity measured using the lost workday equivalent (LWDE) index and health care utilization in asthmatics depending on age, geographical location, time period, severity, and level of asthma control. In this cross-sectional, observational, epidemiological multicenter study, 120 allergists nationwide were asked to select asthmatic patients aged 18 to 65 years who were evenly distributed according to the 4 levels of asthma severity (Global Initiative on Asthma) during 3 different seasons. The participants collected sociodemographic data, spirometry values, Asthma Control Test (ACT) score, health care utilization data, perceived stress according to the Impact on Work Productivity Index (IMPALA, indice del Impacto de la Enfermedad en la Productividad Laboral), and score on the Sheehan disability scale. The LWDE index was used to measure the number of workdays lost and the number of workdays with asthma symptoms combined with the percentage for average performance at work. The study sample comprised 1098 patients (58.7% females; 48.5% aged 18-40 and 51.5% aged 41-65). According to the ACT score, disease was uncontrolled in 57.6% of patients, well controlled in 32.8%, and totally controlled in 9.6%. The mean cost due to workdays lost was Euro 285.81/patient/mo (95% CI, Euro 252.71-318.92). Indirect costs were significantly higher in older patients (41-65 years, Euro 405.08; 95% CI, 348.97-461.19), patients with more severe disease (Euro 698.95; 95% CI, 588.63-809.27), and patients with more poorly controlled asthma (Euro 466.86; 95% CI, Euro 414.39-519.33). The average cost of health care units per patient for each 3-month period was Euro1317.30 (95% CI, Euro 1151.34-Euro 1483.26). Indirect costs were significantly higher in older patients (Euro 2104.00 in patients aged 18-40 vs Euro 3301.55 in patients aged 41-65), in northern and central regions, in severe disease (Euro 2921.63), and in more poorly controlled asthma (Euro 1799.42). Our findings could prove useful for physicians and health care providers.

This article reviews the various types of technical and clinical denials that are usually "written off" and proposes strategies to prevent this loss. For purposes of this writing, avoidable technical and clinical denial write-offs are defined as revenue lost from "first-pass" denials rejections. For example, a procedure that requires an authorization is performed without having had an authorization obtained. After appeals and attempts to recoup the revenue, often unsuccessful, the organization ultimately "writes off" the revenue as not collectable. The question to ask is: Are these claims really not collectable or can actionable steps be taken to conserve these dollars and improve the bottom line? Acute care hospitals, physician offices, and clinics. In today's environment, the need to manage costs is ubiquitous. Cost management is on the priority list of all savvy health care executives, even if margins are healthy, revenue is under pressure, and the magnitude of cost reduction needed is greater than what past efforts have achieved. As hospitals and physician clinics prioritize areas for improvement, reduction in lost revenue-especially avoidable lost revenue-should be at the top of the list. Attentively managing claim denial write-offs will significantly reduce lost revenue. There is significant interface between case management and the revenue cycle. Developing core competencies for reducing clinical and technical denials should be a critical imperative in overall cost management strategy. Case managers are well placed to prevent these unnecessary losses through accurate status determination and clinical documentation review. These clinical professionals can also provide insight into work flow and other processes inherent in the preauthorization process.
Work-attributed illness arising from excess heat exposure in Ontario, 2004-2010.
Fortune, Melanie K; Mustard, Cameron A; Etches, Jacob J C; Chambers, Andrea G
2013-09-12
To describe the incidence of occupational heat illness in Ontario. Heat illness events were identified in two population-based data sources: work-related emergency department (ED) records and lost time claims for the period 2004-2010 in Ontario, Canada. Incidence rates were calculated using denominator estimates from national labour market surveys and estimates were adjusted for workers' compensation insurance coverage. Proportional morbidity ratios were estimated for industry, occupation and tenure of employment. There were 785 heat illness events identified in the ED encounter records (incidence rate 1.6 per 1,000,000 full-time equivalent (FTE) months) and 612 heat illness events identified in the lost time claim records (incidence rate 1.7 per 1,000,000 FTE months) in the seven-year observation period with peak incidence observed in the summer months. The risk of heat illness was elevated for men, young workers, manual workers and those with shorter employment tenure. A higher proportion of lost time claims attributed to heat illness were observed in the government services, agriculture and construction sectors relative to all lost time claims. Occupational heat illnesses are experienced in Ontario's population and are observed in ED records and lost time claims. The variation of heat illness incidence observed with worker and industry characteristics, and over time, can inform prevention efforts by occupational health services in Ontario.
Bioterrorism preparedness--Part II. Smallpox vaccination in a hospital setting.
Jacobs, Lenworth M; Emanuelsen, Kathy; McKay, Charles; Burns, Karyl
2004-01-01
The threat of using smallpox as an agent for bioterrorism resulted in a directive for the creation of smallpox response teams. In Connecticut, The Commissioner of the Department of Public Health convened public health and hospital leadership to plan for the vaccination of these teams. The purpose of this paper is to provide a description of the vaccination program at Hartford Hospital, a Center of Excellence for Bioterrorism Preparedness, and to report the results of a survey of the vaccinees regarding the vaccination experience. Ninety persons were vaccinated. Six individuals experienced low-grade fever and 10 had axillary node swelling. One individual experienced significant fatigue. A total of six persons lost time from work. Four lost one day and two persons lost between four to five days of work. There was no autoinoculation, transfer inoculation, vaccinia or any other significant complication. Survey results indicate that most vaccinees felt positive about the experience.

The aim of this research was to perform the nutritional screening and clinical assessment of malnutrition and of cachexia as well as the need for enteral nutritional support. We used an international questionnaire for nutrition screening and clinical assessment of malnutrition. 103 cancer patients participated in the research. The results indicate that 80patients (78%) have recently unintentionally lost weight in the last six months. Of those 80 patients 12 (15%) have lost more than 15 kilograms. Three patients (3%) suffer from hunger because of their inability to eat. Presence of multiple (3 or more) symptoms (nausea, vomiting, diarrhea or anorexia) was reported by 11 patients (11%). Severe work dysfunction was found in 28 patients (27%). 14 patients (14%) experience significant loss of musculature (musculus quadriceps femoris, musculus deltoideus). The obtained results indicate that 15patients (14%) are severely, and 39 patients (38%) are moderately undernourished. This survey confirmed the significance of nutritional screening in cancer patients, as it detected 30 patients (29%) who required introduction of enteral nutrition.
Health and productivity as a business strategy.

The objective of this study is to assess the magnitude of health-related lost productivity relative to medical and pharmacy costs for four employers and assess the business implications of a "full-cost" approach to managing health. A database was developed by integrating medical and pharmacy claims data with employee self-report productivity and health information collected through the Health and Work Performance Questionnaire (HPQ). Information collected on employer business measures were combined with this database to model health-related lost productivity. 1) Health-related productivity costs were more than four times greater than medical and pharmacy costs. 2) The full cost of poor health is driven by different health conditions than those driving medical and pharmacy costs alone. This study demonstrates that Integrated Population Health & Productivity Management should be built on a foundation of Integrated Population Health & Productivity Measurement. Therefore, employers would reveal a blueprint for action for their integrated health and productivity enhancement strategies by measuring the full health and productivity costs related to the burdens of illness and health risk in their population.
Memorising Milton's Paradise lost: a study of a septuagenarian exceptional memoriser.
Seamon, John G; Punjabi, Paawan V; Busch, Emily A
2010-07-01
At age 58, JB began memorising Milton's epic poem Paradise Lost. Nine years and thousands of study hours later, he completed this process in 2001 and recalled from memory all 12 books of this 10,565-line poem over a 3-day period. Now 74, JB continues to recite this work. We tested his memory accuracy by cueing his recall with two lines from the beginning or middle of each book and asking JB to recall the next 10 lines. JB is an exceptional memoriser of Milton, both in our laboratory tests in which he did not know the specific tests or procedures in advance, and in our analysis of a videotaped, prepared performance. Consistent with deliberate practice theory, JB achieved this remarkable ability by deeply analysing the poem's structure and meaning over lengthy repetitions. Our findings suggest that exceptional memorisers such as JB are made, not born, and that cognitive expertise can be demonstrated even in later adulthood.
Retrieving the lost fermionic entanglement by partial measurement in noninertial frames

The initial entanglement shared between inertial and accelerated observers degrades due to the influence of the Unruh effect. Here, we show that the Unruh effect can be completely eliminated by the technique of partial measurement. The lost entanglement could be entirely retrieved or even amplified, which is dependent on whether the optimal strength of reversed measurement is state-independent or state-dependent. Our work provides a novel and unexpected method to recover the lost entanglement under Unruh decoherence and exhibits the ability of partial measurement as an important technique in relativistic quantum information.
Collaborative hospital orientation: simulation as a teaching strategy.
Lamers, Karilyn; Janisse, Lisa; Brown, Gail; Butler, Carol; Watson, Barb
2013-01-01
For nurses, the stress caused by entering a new place of employment may give rise to insecurity and a lack of confidence. Lack of confidence in one's nursing skills can affect performance and, ultimately, patient care and safety. In healthcare, growing fiscal constraints have resulted in lost resources, and support for new nursing staff is limited by both time and cost considerations. Clinical educators therefore must find innovative ways to provide education and support, including creative learning modalities that facilitate nurses' transition into a new role and work environment.
RoboGlove: Initial Work Toward a Robotically Assisted EVA Glove

The RoboGlove is a device designed to provide additional grip strength or endurance for a user. In applying this Robonaut 2 spinoff technology to the Phase VI Space Suit glove, the project is using robotic tendons and actuators to regain some of the hand performance that is lost when wearing a pressurized glove. An array of sensors embedded into the finger softgoods provides input to the control system which retracts the tendons, helping to close the user's hand. While active, this system provides augmentation, but is nonintrusive to glove usage when disabled.

The effects of traumatic loss on children who reported a friend or acquaintance killed in the 1995 Oklahoma City bombing of a federal office building were examined. Twenty-seven children who lost a friend or acquaintance and 27 demographically matched controls were assessed eight to ten months after the bombing. All but three of the children continued to experience posttraumatic stress symptoms. Those who lost a friend watched significantly more bombing-related television coverage than those without losses. Those who lost a friend had significantly more posttraumatic stress symptoms at the time of the assessment than those who lost an acquaintance. Parents and those working with children should be alert to the impact of loss even when it involves nonrelatives.
Whatever happened to "What might have been"? Regrets, happiness, and maturity.
King, Laura A; Hicks, Joshua A
2007-10-01
Although lost opportunities and mistaken expectations are unpleasant to think and talk about, these experiences may have a role to play in personality development. Drawing on research using narratives of lost possible selves, the authors review the relations of regrettable experiences to 2 important and independent aspects of maturity, happiness and complexity. Thinking about a lost possible self is related to concurrent regrets, distress, and lowered well-being; however, elaborating on a lost possible self is related, concurrently, to complexity and predicts complexity, prospectively, over time. In this article, the authors describe the role that regrettable experiences have in promoting both happiness and complexity. Finally, expanding on previous work, the authors examine potential affordances of happy maturity and suggest psychological capacities that may promote happy maturity.

Estimates of health-related quality of life (HRQoL) and work/school absences for influenza are typically based on medically attended cases or those meeting influenza-like-illness (ILI) case definitions and thus biased towards severe disease. Although community influenza cases are more common, estimates of their effects on HRQoL and absences are limited. To measure quality-adjusted life days and years (QALDs and QALYs) lost and work/school absences among community cases of acute respiratory infections (ARI), ILI and influenza A and B and to estimate community burden of QALY loss and absences from influenza. Flu Watch was a community cohort in England from 2006 to 2011. Participants were followed up weekly. During respiratory illness, they prospectively recorded daily symptoms, work/school absences and EQ-5D-3L data and submitted nasal swabs for RT-PCR influenza testing. Average QALD lost was 0.26, 0.93, 1.61 and 1.84 for ARI, ILI, H1N1pdm09 and influenza B cases, respectively. 40% of influenza A cases and 24% of influenza B cases took time off work/school with an average duration of 3.6 and 2.4 days, respectively. In England, community influenza cases lost 24 300 QALYs in 2010/11 and had an estimated 2.9 million absences per season based on data from 2006/07 to 2009/10. Our QALDs and QALYs lost and work and school absence estimates are lower than previous estimates because we focus on community cases, most of which are mild, may not meet ILI definitions and do not result in healthcare consultations. Nevertheless, they contribute a substantial loss of HRQoL on a population level. © 2017 The Authors. Influenza and Other Respiratory Viruses. Published by John Wiley & Sons Ltd.
Work expectations, cultural sensitivity, schizophrenia, and suicide risk in male patients.
Lewine, Richard; Shriner, Brooke
2009-04-01
This study examines the relationship between "vocational lost potential" and suicide risk in a mixed sample of severely and persistently mentally ill psychiatric patients. We hypothesized that increased lost potential would be associated with increased suicide risk indicator ratings and that this relationship would be moderated by patients' social class of origin. One hundred sixty-seven psychiatric patients rated a range of clinical symptoms and vocational expectations, as well as providing sociodemographic information including their parents' years of education (used as a proxy for social class of origin). Contrary to our prediction, the results suggest that individuals from higher social class who experience minimal lost potential may be at a higher risk for suicide than their counterparts with maximal lost potential; this is especially true when based on fathers' educational level. In discussing the clinical implications of our findings, we suggest that a subgroup of individuals' vocational success may depend on first addressing the cognitive conflict inherent in the phenomenon of lost potential.
The estimated cost of "no-shows" in an academic pediatric neurology clinic.
Guzek, Lindsay M; Gentry, Shelley D; Golomb, Meredith R
2015-02-01
Missed appointments ("no-shows") represent an important source of lost revenue for academic medical centers. The goal of this study was to examine the costs of "no-shows" at an academic pediatric neurology outpatient clinic. This was a retrospective cohort study of patients who missed appointments at an academic pediatric neurology outpatient clinic during 1 academic year. Revenue lost was estimated based on average reimbursement for different insurance types and visit types. The yearly "no-show" rate was 26%. Yearly revenue lost from missed appointments was $257,724.57, and monthly losses ranged from $15,652.33 in October 2013 to $27,042.44 in January 2014. The yearly revenue lost from missed appointments at the academic pediatric neurology clinic represents funds that could have been used to improve patient access and care. Further work is needed to develop strategies to decrease the no-show rate to decrease lost revenue and improve patient care and access. Copyright © 2015 Elsevier Inc. All rights reserved.

In this work, a new dual-evaporator CO2 transcritical refrigeration cycle with two ejectors is proposed. In this new system, we proposed to recover the lost energy of condensation coming off the gas cooler and operate the refrigeration cycle ejector free and enhance the system performance and obtain dual-temperature refrigeration simultaneously. The effects of some key parameters on the thermodynamic performance of the modified cycle are theoretically investigated based on energetic and exergetic analysis. The simulation results for the modified cycle indicate more effective system performance improvement than the single ejector in the CO2 vapor compression cycle using ejector as an expander ranging up to 46%. The exergetic analysis for this system is made. The performance characteristics of the proposed cycle show its promise in dual-evaporator refrigeration system.
Stereotype Fit Effects for Golf Putting Nonexperts
Grimm, Lisa R.; Lewis, Benjamin; Maddox, W. Todd; Markman, Arthur B.
2015-01-01
Research has connected stereotype threat and regulatory fit by showing improved performance for individuals with negative stereotypes when they focused on minimizing potential losses. In the current study, non-Black participants, who were non-experts at golf putting, were told that a golf-putting task was diagnostic of natural athletic ability (i.e., negative stereotype) or sports intelligence (i.e., positive stereotype). Participants tried to maximize earned points or minimize lost points assigned after every putt, which was calculated based on the distance to a target. We demonstrate better performance for participants experiencing a fit between their global task stereotype and the task goal, and argue that regulatory fit allows for increased attention on the strategies beneficial for task performance. Interestingly, we find that performance of individuals high in working memory capacity suffers greatly when those individuals experience a regulatory mismatch. PMID:27162703
Localized Fault Recovery for Nested Fork-Join Programs

Kestor, Gokcen; Krishnamoorthy, Sriram; Ma, Wenjing
Nested fork-join programs scheduled using work stealing can automatically balance load and adapt to changes in the execution environment. In this paper, we design an approach to efficiently recover from faults encountered by these programs. Specifically, we focus on localized recovery of the task space in the presence of fail-stop failures. We present an approach to efficiently track, under work stealing, the relationships between the work executed by various threads. This information is used to identify and schedule the tasks to be re-executed without interfering with normal task execution. The algorithm precisely computes the work lost, incurs minimal re-execution overhead,more » and can recover from an arbitrary number of failures. Experimental evaluation demonstrates low overheads in the absence of failures, recovery overheads on the same order as the lost work, and much lower recovery costs than alternative strategies.« less
Comparison of data sources for the surveillance of work injury
Chambers, Andrea; McLeod, Christopher; Bielecky, Amber; Smith, Peter M
2012-01-01
Objective The objective of this study was to compare the incidence of work-related injury and illness presenting to Ontario emergency departments to the incidence of worker's compensation claims reported to the Ontario Workplace Safety & Insurance Board over the period 2004–2008. Methods Records of work-related injury were obtained from two administrative data sources in Ontario for the period 2004–2008: workers' compensation lost-time claims (N=435 336) and records of non-scheduled emergency department visits where the main problem was attributed to a work-related exposure (N=707 963). Denominator information required to compute the risk of work injury per 2 000 000 work hours, stratified by age and gender was estimated from labour force surveys conducted by Statistics Canada. Results The frequency of emergency department visits for all work-related conditions was approximately 60% greater than the incidence of accepted lost-time compensation claims. When restricted to injuries resulting in fracture or concussion, gender-specific age differences in injury incidence were similar in the two data sources. Between 2004 and 2008, there was a 14.5% reduction in emergency department visits attributed to work-related causes and a 17.8% reduction in lost-time compensation claims. There was evidence that younger workers were more likely than older workers to seek treatment in an emergency department for work-related injury. Conclusions In this setting, emergency department records available for the complete population of Ontario residents are a valid source of surveillance information on the incidence of work-related disorders. Occupational health and safety authorities should give priority to incorporating emergency department records in the routine surveillance of the health of workers. PMID:22267447

Debates about the productivity impact of work accommodations typically focus on employment and labor force participation outcomes. This study considers whether accommodations mediate on-the-job productivity losses among employees who report health problems. The study uses ordered logistic regression to predict employees' self-reported productivity losses as a function of health problems and experiences with needed work accommodations. On average, the odds that an employee who did not get a needed accommodation reported higher levels of lost productivity are 5.11 times the odds for an employee who got a needed accommodation. Although health problems make it difficult for many employees to perform well on the job, accommodations could reduce productivity losses in some cases. Nonetheless, more research on the impact of specific kinds of accommodations for different chronic conditions is warranted.

The aim was to establish how patients experience the impact of spondyloarthritis (SpA) on work disability and working life. The survey was performed in 17/20 regions in Italy (1 January to 31 March 2013). A multiple-choice questionnaire was published on the official website of the sponsor - the National Association of Rheumatic Patients (ANMAR) - and hard-copies were distributed at outpatient clinics for rheumatic patients. Respondents (n = 770) were of both sexes (56 % men), educated (62 % at high school or more), of working age (75 % aged ≤60 years), and affected by SpA. The most common types diagnosed were ankylosing spondylitis (AS) (39 %) and psoriatic arthritis (PsA) (36 %). Respondents were working full-time (45 %), part-time (8 %) or had retired (22 %); 15 % were unemployed (for reasons linked to the disease or for other reasons, students or housewives). Patients reported disability (39 %), were receiving disability benefits (34 %), were experiencing important limitations that were hindering their professional development/career (36 %) and some had to change/leave their job or lost it because of SpA (21 %). Employed respondents (n = 383) had worked on average 32.2 h in the last 7 days. More hours of work were lost over the last 7 days due to SpA (2.39 h vs 1.67 h). The indirect costs of the disease amounted to €106/week for patients reporting well-being/good physical conditions/improvement and €216/week for those reporting permanent impairment. Most patients were in the midst of their productive years and were experiencing considerable difficulties in carrying out their job because of the disease: half of them reported disability and one third were experiencing important limitations in their career perspective.

Losses to follow-up after initiation of antiretroviral therapy (ART) are common in Africa and are a considerable obstacle to understanding the effectiveness of nascent treatment programs. We sought to characterize, through a sampling-based approach, reasons for and outcomes of patients who become lost to follow-up. Cohort study. We searched for and interviewed a representative sample of lost patients or close informants in the community to determine reasons for and outcomes among lost patients. Three thousand six hundred twenty-eight HIV-infected adults initiated ART between January 1, 2004 and September 30, 2007 in Mbarara, Uganda. Eight hundred twenty-nine became lost to follow-up (cumulative incidence at 1, 2, and 3 years of 16%, 30%, and 39%). We sought a representative sample of 128 lost patients in the community and ascertained vital status in 111 (87%). Top reasons for loss included lack of transportation or money and work/child care responsibilities. Among the 111 lost patients who had their vital status ascertained through tracking, 32 deaths occurred (cumulative 1-year incidence 36%); mortality was highest shortly after the last clinic visit. Lower pre-ART CD4 T-cell count, older age, low blood pressure, and a central nervous system syndrome at the last clinic visit predicted deaths. Of patients directly interviewed, 83% were in care at another clinic and 71% were still using ART. Sociostructural factors are the primary reasons for loss to follow-up. Outcomes among the lost are heterogeneous: both deaths and transfers to other clinics were common. Tracking a sample of lost patients is an efficient means for programs to understand site-specific reasons for and outcomes among patients lost to follow-up.
Short-term Lost Productivity per Victim: Intimate Partner Violence, Sexual Violence, or Stalking.

The purpose of this study is to estimate victims' lifetime short-term lost productivity because of intimate partner violence, sexual violence, or stalking. U.S. nationally representative data from the 2012 National Intimate Partner and Sexual Violence Survey were used to estimate a regression-adjusted average per victim (female and male) and total population number of cumulative short-term lost work and school days (or lost productivity) because of victimizations over victims' lifetimes. Victims' lost productivity was valued using a U.S. daily production estimate. Analysis was conducted in 2017. Non-institutionalized adults with some lifetime exposure to intimate partner violence, sexual violence, or stalking (n=6,718 respondents; survey-weighted n=130,795,789) reported nearly 741 million lost productive days because of victimizations by an average of 2.5 perpetrators per victim. The adjusted per victim average was 4.9 (95% CI=3.9, 5.9) days, controlling for victim, perpetrator, and violence type factors. The estimated societal cost of this short-term lost productivity was $730 per victim, or $110 billion across the lifetimes of all victims (2016 USD). Factors associated with victims having a higher number of lost days included a higher number of perpetrators and being female, as well as sexual violence, physical violence, or stalking victimization by an intimate partner perpetrator, stalking victimization by an acquaintance perpetrator, and sexual violence or stalking victimization by a family member perpetrator. Short-term lost productivity represents a minimum economic valuation of the immediate negative effects of intimate partner violence, sexual violence, and stalking. Victims' lost productivity affects family members, colleagues, and employers. Published by Elsevier Inc.

Work-related factors of presenteeism: The mediating role of mental and physical health.
Pohling, Rico; Buruck, Gabriele; Jungbauer, Kevin-Lim; Leiter, Michael P
2016-04-01
Even though work-related factors have been found to play a crucial role in predicting presenteeism, studies investigating established theoretical frameworks of job design features and, in particular, underlying mechanisms are still very scarce. The objective of this study was to investigate the influence of the areas of work life according to the Areas of Worklife Scale (AWS; Leiter & Maslach, 2004) on presenteeism. We examined mental and physical health as the underlying process of this relationship and assessed 2 presenteeism outcome measures and their relationship to each other-that is, the frequency of acts of presenteeism and work productivity. Using a cross-sectional design, the study was conducted in a sample of 885 employees from German public service. Results showed that the influence of some, but not all, areas of work life (workload, control, reward, and values) on both acts of presenteeism and health-related lost productivity was mediated by health indicators (well-being and musculoskeletal complaints). Moreover, we found a relationship between health-related lost productivity and acts of presenteeism. The present research clarifies the importance of work-related factors as antecedents of sickness presenteeism. The findings of our study also emphasize the necessity to include both acts of presenteeism and health-related lost productivity in presenteeism research and prevention. Presenteeism should be included as a measure in health prevention interventions because it reflects a crucial part of employee health that is not covered by other measures.

Multi-functional foot use during running in the zebra-tailed lizard (Callisaurus draconoides).
Li, Chen; Hsieh, S Tonia; Goldman, Daniel I
2012-09-15
A diversity of animals that run on solid, level, flat, non-slip surfaces appear to bounce on their legs; elastic elements in the limbs can store and return energy during each step. The mechanics and energetics of running in natural terrain, particularly on surfaces that can yield and flow under stress, is less understood. The zebra-tailed lizard (Callisaurus draconoides), a small desert generalist with a large, elongate, tendinous hind foot, runs rapidly across a variety of natural substrates. We use high-speed video to obtain detailed three-dimensional running kinematics on solid and granular surfaces to reveal how leg, foot and substrate mechanics contribute to its high locomotor performance. Running at ~10 body lengths s(-1) (~1 m s(-1)), the center of mass oscillates like a spring-mass system on both substrates, with only 15% reduction in stride length on the granular surface. On the solid surface, a strut-spring model of the hind limb reveals that the hind foot saves ~40% of the mechanical work needed per step, significant for the lizard's small size. On the granular surface, a penetration force model and hypothesized subsurface foot rotation indicates that the hind foot paddles through fluidized granular medium, and that the energy lost per step during irreversible deformation of the substrate does not differ from the reduction in the mechanical energy of the center of mass. The upper hind leg muscles must perform three times as much mechanical work on the granular surface as on the solid surface to compensate for the greater energy lost within the foot and to the substrate.

Construction workers globally face disproportionate threats to health and wellbeing, constituted by the nature of the work they perform. The workplace fatalities and lost-time injuries experienced by construction workers are significantly greater than in other forms of work. This paper draws on the culture-centered approach (CCA) to dialogically articulate meanings of workplace risks and injuries, voiced by Bangladeshi migrant construction workers in Singapore. The narratives voiced by the participants suggest an ecological approach to workplace injuries in the construction industries, attending to food insecurity, lack of sleep, transportation, etc. as contextual features of work that shape the risks experienced at work. Moreover, participant voices point to the barriers in communication, lack of understanding, and experiences of incivility as features of work that constitute the ways in which they experience injury risks. The overarching discourses of productivity and efficiency constitute a broader climate of threats to worker safety and health. PMID:28146056
Productivity impact of headache on a heavy-manufacturing workforce in Turkey
2013-01-01
Background Headache disorders cause substantial productivity losses through absenteeism and impaired effectiveness at work (presenteeism). We measured productivity losses from both causes at a heavy-manufacturing company with a largely male workforce in north-western Turkey. Methods We used the HALT Index as the survey instrument. We first assessed productivity losses by surveying the entire workforce. Because we anticipated much non-participation, we also applied HALT at the annual health-checks provided to all employees by the company’s on-site health clinic. Results Mean age of the workforce (N = 7,200) was 31 yr. About two thirds (90% male) were manual workers rotating weekly through early, late and night shifts. One third (50% male) were clerical/managerial, working a standard 5-day week. In the first assessment, 3,939 questionnaires (54.7%) were returned with usable data. In the previous 3 months, absenteeism of ≥1 day was reported by 360 respondents (9.1%), of whom 4 (0.10%) recorded ≥45 days (average per worker: 0.92 days/yr). Presenteeism equivalent to ≥1 day’s absence was reported by 1,187 respondents (29.4%) (average per worker: 6.0 days/yr). We estimated that 23,519 days/yr were lost in total among respondents (2.3% of workforce capacity). In the first 6 months of annual health-checks, 2,691 employees (37.4%) attended (94.4% male). Absenteeism was reported by 40 (1.5%), with 74 days lost, presenteeism by 348 (12.9%), with 1,240 days lost. We estimated that, altogether, 41,771 man-days/yr were lost in the entire workforce (2.4% of capacity; 94% due to presenteeism), closely matching the earlier estimate. A small minority (5.7%) of those with headache, who were only 2.5% of the workforce, accounted for >45% of presenteeism-related lost productivity. Conclusion The high productivity losses in a largely male workforce were surprising. Possible factors were the nature of the work – manual labour for two thirds, often heavy – and the recurring schedule disturbances of shift-work. There was a highly-disabled minority. PMID:24171915

Although notifying an employer of a lost-time work-related injury is a legal requirement in many jurisdictions, employees frequently do not report such injuries. Based on data from 21,345 young part-time Canadian workers (55% male), we found that 21% of respondents had experienced at least one lost-time injury, with about half reporting the injury to an employer and a doctor. Respondents provided 10 reasons for avoiding reporting lost-time injuries, with perceived low severity of the injury, negative reactions of others, and ambiguity about whether work caused the injury as the most common ones. Additional analysis of these categories revealed that young males cited concern about their self-identity as a reason for not reporting an injury more often than young females did. We discuss the findings in terms of implications for management practice (i.e., educating young workers about accurate injury reporting) and public policy. Targeted campaigns should be developed for young workers, especially young male workers, who are less likely to report injuries than young female workers, to understand the importance of and to encourage injury reporting.

Different architectures of creativity: Louis and Nathaniel Kahn.
Golinelli, Paola
2014-04-01
The author analyzes Nathaniel Kahn's documentary film My Architect: A Son's Journey, a tribute to the writer-director's father Louis, the famous architect, who died suddenly when Nathaniel was eleven years old. The film's poetic, evocative images form a testimony to the silent working through that Nathaniel did in searching for his lost father and to the complex intertwining of mourning and creativity. Creativity is seen as both the cause and the effect of working through, as it gives life to a new meaning and allows replacement of the lost object by an object found again. Bereavement, symbolization, and the birth of representation appear to be connected with one another, both when the most elementary representations are involved and when the more complex and artistic ones are. Where and when it is possible to recover a representation that can survive the absence of the lost object, there is a potentially creative psychic space that can be made fertile again. © 2014 The Psychoanalytic Quarterly, Inc.

Numerical time integration schemes for Landau-Lifshitz magnetization dynamics are considered. Such dynamics preserves the magnetization amplitude and, in the absence of dissipation, also implies the conservation of the free energy. This property is generally lost when time discretization is performed for the numerical solution. In this work, explicit numerical schemes based on Runge-Kutta methods are introduced. The schemes are termed pseudo-symplectic in that they are accurate to order p, but preserve magnetization amplitude and free energy to order q > p. An effective strategy for adaptive time-stepping control is discussed for schemes of this class. Numerical tests against analytical solutions for the simulation of fast precessional dynamics are performed in order to point out the effectiveness of the proposed methods.
Long-term cost and life-expectancy consequences of hypertension.
Kiiskinen, U; Vartiainen, E; Puska, P; Aromaa, A
1998-08-01
To estimate hypertension's long-term cost and impact on life expectancy. A 19-year individual follow-up study. Subjects were categorized according to their baseline (1972) diastolic blood pressure (DBP) level into three groups: normotensive (DBP < 95 mmHg), mildly hypertensive (DBP 95-104 mmHg), and severely hypertensive (DBP > 104 mmHg). By using their social security identification numbers, we linked the subjects to a set of national registers covering hospital admissions, use of major drugs, absence due to sickness, disability pensions, and deaths. A random population sample of 10 284 men and women aged 25-59 years from the provinces of Kuopio and North Karelia in eastern Finland. The numbers of years of life and years of work lost, the cost of drugs and hospitalization, and the value of productivity lost due to disability and premature mortality. The difference in life expectancy between normotensive and severely hypertensive men was 2.7 years, of which 2.0 years was due to cardiovascular disease (CVD). Among women the corresponding differences were 2.0 and 1.5 years. Severely hypertensive men lost 2.6 years of work more than did normotensive men, of which 1.7 years was due to CVD. Among women the differences were 2.2 and 1.3 years. The mean undiscounted total costs (USA dollars at 1992 prices) were $132 500 among normotensive, $146 500 among mildly hypertensive, and $219 300 among severely hypertensive men, of which CVD accounted for 28, 39, and 43%, respectively. More than 90% of the total costs were indirect productivity losses. Among women the total costs were lower for all DBP categories, as were the shares of CVD-related costs. The proportional increase in costs on going from the lowest to the highest DBP category was, however, somewhat larger among women. On the population level, severe hypertension leads to considerable losses in terms of years of life lost, years of work lost, and costs. However, the overall impact of mild hypertension is much more limited.

This article compares military research projects during the Second World War to develop nuclear weapons in Germany and Japan, two countries who lost the war and failed to create nuclear weapons. The performance and motivations of the scientists, as well as the institutional support given the work, is examined, explaining why, in each case, the project went as far as it did-but no further. The story is carried over into the postwar period, when the two cultures and their scientists had to deal with the buildup of nuclear weapons during the cold war and the new nuclear power industry.

Kukacka, L. E.
Advances in the development of new materials continue to be made in the geothermal materials project. Many successes have already been accrued and the results used commercially. In FY-91, work was focused on reducing well drilling, fluid transport and energy conversion costs. Specific activities performed included lightweight CO2 resistant well cements, thermally conductive and scale resistant protective liner systems, chemical systems for lost circulation control, corrosion mitigation in process components at The Geysers, and elastomer-metal bonding systems. Efforts to transfer the technologies developed in these efforts to other energy-related sectors of the economy continued, and considerable success was achieved.
Productivity losses associated with diabetes in the US.
Ng, Y C; Jacobs, P; Johnson, J A
2001-02-01
The objective of this study was to estimate the cost of productivity losses in the U.S. attributable to diabetes, with regard to specific demographic and disease-related characteristics in the U.S.. We used the 1989 National Health Interview Survey, a random survey of individuals in the U.S. that included a diabetes supplement. Data on individuals were obtained for labor force participation, hours of work, demographic and occupational characteristics, self-reported health status, and several variables that indicated the presence, duration, and severity (complications) of diabetes. Using multivariate regression analyses, we estimated the association of independent variables (e.g., demographics, health, and diabetes status) with labor force participation, hours of work lost, and the economic value of lost work attributable to diabetes and its complications and duration. In general, the presence of diabetes and complications were found to be related to workforce participation variables. The magnitude of the lost-productivity costs depended on personal characteristics and on the presence and status of diabetes. In general, the loss of yearly earnings amounted to about a one-third reduction in earnings and ranged from $3,700 to $8,700 per annum. Diabetes has a considerable net effect on earnings, and the complications and duration of diabetes have compound effects. Our findings have implications for the cost-effectiveness of diabetes control; the presence of complicating factors is the single most important predictive factor in lost productivity costs attributable to diabetes, and thus the avoidance or retardation of complications will have an impact on indirect health-related costs.

Northern Ontario, Canada has a larger elder population, more resource-based employment, and limited access to physicians and specialists compared to southern Ontario. Given these important differences, it is possible that work disability rates will vary between the two Ontario jurisdictions. To determine the association between time lost due to workplace injuries and illnesses occurring in northern vs southern Ontario and work disability duration from 2006--2011. The study base included all lost-time claims approved by the Workplace Safety and Insurance Board in Ontario, Canada for workplace injury or illness compensation occurring between January 1, 2006 and December 31, 2011. All eligible participants had to be 18 years of age or older at the time of making the claim and participants were excluded if one of the three variables used to determine location (claimant home postal code, workplace geographical code, and WSIB firm location) were missing. Multivariable proportional hazards regression models were used to estimate hazard ratios and 95% confidence intervals adjusted for sex, age, occupation, part of body, and nature of injury relating Ontario geographical location to compensated time off work. A total of 156 453 lost-time claims were approved over the study period. Injured and ill workers from northern Ontario were 16% less likely to return to work than those from southern Ontario. Adjustment for potential confounding factors had no effect. The disability duration in northern Ontario is longer than that in southern Ontario. Future research should focus on assessing the relevant factors associated with this observation to identify opportunities for intervention.
Does part-time sick leave help individuals with mental disorders recover lost work capacity?
Andrén, Daniela
2014-06-01
This paper aims to answer the question whether combining sick leave with some hours of work can help employees diagnosed with a mental disorder (MD) increase their probability of returning to work. Given the available data, this paper analyzes the impact of part-time sick leave (PTSL) on the probability of fully recovering lost work capacity for employees diagnosed with an MD. The effects of PTSL on the probability of fully recovering lost work capacity are estimated by a discrete choice one-factor model using data on a nationally representative sample extracted from the register of the National Agency of Social Insurance in Sweden and supplemented with information from questionnaires. All individuals in the sample were 20-64 years old and started a sickness spell of at least 15 days between 1 and 16 February 2001. We selected all employed individuals diagnosed with an MD, with a final sample of 629 individuals. The results show that PTSL is associated with a low likelihood of full recovery, yet the timing of the assignment is important. PTSL's effect is relatively low (0.015) when it is assigned in the beginning of the spell but relatively high (0.387), and statistically significant, when assigned after 60 days of full-time sick leave (FTSL). This suggests efficiency improvements from assigning employees with an MD diagnosis, when possible, to PTSL. The employment gains will be enhanced if employees with an MD diagnosis are encouraged to return to work part-time after 60 days or more of FTSL.

Loss of expensive mud could lead to major financial problem in executing a drilling project and is one of the biggest problems that need to be tackled during drilling. Synthetic Based Mud (SBM) is the most stable state of the art drilling mud used in current drilling technologies. However, the problem with lost circulation is still inevitable. The focus of this project is to develop a new potential waste material from banana peel in order to combat lost circulation in SBM. Standard industrial Lost Circulation Material (LCM) is used to compare the performance of banana peel as LCM in SBM. The effects of different sizing of banana peels (600 micron, 300 micron and 100 micron) were studied on the rheological and filtration properties of SBM and the bridging performance of banana peel as LCM additive. The tests were conducted using viscometer, HTHP filter press and sand bed tester. Thermal analysis of banana peel was also studied using TGA. According to the results obtained, 300 and 100 micron size of banana peel LCM exhibited an improved bridging performance by 65% as compared to industrial LCM. However, banana peel LCM with the size of 600 micron failed to act as LCM due to the total invasion of mud into the sand bed.

Certain risk factors associated with overweight and obesity may lead to reduced productivity in the workforce (i.e., increased absenteeism and presenteeism). Participants in a large, Internet-based worksite weight loss intervention, who were present at follow-up (N = 1,030), completed a self-reported productivity measure (World Health Organization’s Health and Work Performance Questionnaire) at baseline and postintervention. Twenty-two percent of the participants lost a clinically meaningful amount of weight (≥5% weight loss). There were no statistically significant (p < .05) relationships between weight change from baseline to 12 months and change scores of absolute or relative absenteeism or for absolute or relative presenteeism. Within a modestly successful Internet-based, worksite weight loss intervention, weight loss did not improve self-reported absenteeism or presenteeism. Further studies are needed to explore the sensitivity of the World Health Organization’s Health and Work Performance Questionnaire and the long-term effects of weight loss on productivity.

Performing an academic exercise aimed at applying the analytical categories from the governance approach developed by Marc Hufty et al., to understand social actors relationships in an investigation and intervention project studying so-cioeconomic conditions and seeking to guarantee health insurance continuity for those workers who had lost their work in the city of Medellin, Colombia, from 2004 to 2007. A process of investigation and intervention was examined as a casestudy in which researchers were one of the actors so involved. Characterising stake-holders included: their level of inclusion/involvement in the problem; their power for influencing public policy proposals; their perceptions and proposals characteristics, power and dynamics regarding the problem of unemployment and health insurance when someone has lost her/his work; and the characteristics of their interaction with other actors. The results showed that the four analytical dimensions proposed by Hufty (actors, social norms, nodal points and processes) were useful for describing and understanding the interaction of the actors involved in the research and intervention proposal being analysed here (i.e. the case-study). It was concluded that the analytical governance framework proposed by Hufty was useful for understanding how the social subjects interacted; these were the rules which were taken for describing their interaction, being the most important nodes for interaction and progresses achieved whilst implementing the intervention proposal.

Wireless sensor networks (WSNs) have emerged as a reliable, low-cost alternative to the traditional wired sensing paradigm. While such networks have made significant progress in the field of structural monitoring, significantly less development has occurred for feedback control applications. Previous work in WSNs for feedback control has highlighted many of the challenges of using this technology including latency in the wireless communication channel and computational inundation at the individual sensing nodes. This work seeks to overcome some of those challenges by drawing inspiration from the real-time sensing and control techniques employed by the biological central nervous system and in particular the mammalian cochlea. A novel bio-inspired wireless sensor node was developed that employs analog filtering techniques to perform time-frequency decomposition of a sensor signal, thus encompassing the functionality of the cochlea. The node then utilizes asynchronous sampling of the filtered signal to compress the signal prior to communication. This bio-inspired sensing architecture is extended to a feedback control application in order to overcome the traditional challenges currently faced by wireless control. In doing this, however, the network experiences high bandwidths of low-significance information exchange between nodes, resulting in some lost data. This study considers the impact of this lost data on the control capabilities of the bio-inspired control architecture and finds that it does not significantly impact the effectiveness of control.
Measuring mining safety with injury statistics: lost workdays as indicators of risk.
Coleman, Patrick J; Kerkering, John C
2007-01-01
Mining in the United States remains one of the most hazardous industries, despite significant reductions in fatal injury rates over the last century. Coal mine fatality rates, for example, have dropped almost a thousand-fold since their peak in 1908. While incidence rates are very important indicators, lost worktime measures offer an alternative metric for evaluating job safety and health performance. The first objective of this study examined the distributions and summary statistics of all injuries reported to the Mine Safety and Health Administration from 1983 through 2004. Over the period studied (1983-2004), there were 31,515,368 lost workdays associated with mining injuries, for an equivalent of 5,700 person-years lost annually. The second objective addressed the problem of comparing safety program performance in mines for situations where denominator data were lacking. By examining the consequences of injuries, comparisons can be made between disparate operations without the need for denominators. Total risk in the form of lost workday sums can help to distinguish between lower- and higher-risk operations or time periods. Our method was to use a beta distribution to model the losses and to compare underground coal mining to underground metal/nonmetal mining from 2000 to 2004. Our results showed the probability of an injury having 10 or more lost workdays was 0.52 for coal mine cases versus 0.35 for metal/nonmetal mine cases. In addition, a comparison of injuries involving continuous mining machines over 2001-2002 versus 2003-2004 showed that the ratio of average losses in the later period to those in the earlier period was approximately 1.08, suggesting increasing risks for such operations. This denominator-free safety measure will help the mining industry more effectively identify higher-risk operations and more realistically evaluate their safety improvement programs. Attention to a variety of metrics concerning the performance of a job safety and health program will enhance industry's ability to manage these programs and reduce risk.
Development of a Work Control System for Propulsion Testing at NASA Stennis

Messer, Elizabeth A.

This paper will explain the requirements and steps taken to develop the current Propulsion Test Directorate electronic work control system for Test Operations. The PTD Work Control System includes work authorization and technical instruction documents, such as test preparation sheets, discrepancy reports, test requests, pre-test briefing reports, and other test operations supporting tools. The environment that existed in the E-Complex test areas in the late 1990's was one of enormous growth which brought people of diverse backgrounds together for the sole purpose of testing propulsion hardware. The problem that faced us was that these newly formed teams did not have a consistent and clearly understood method for writing, performing or verifying work. A paper system was developed that would allow the teams to use the same forms, but this still presented problems in the large amount of errors occurring, such as lost paperwork and inconsistent implementation. In a sampling of errors in August 1999, the paper work control system encountered 250 errors out of 230 documents released and completed, for an error rate of 111%.

We describe medical care received through workers' compensation (WC) and union-provided insurance surrounding work-related back injuries and examine relationships between care provided and time off work among a large cohort of carpenters. Union records identified a cohort of 20,642 carpenters working in Washington State from 1989-2003 and their private health insurance claims. These data were linked to workers' compensation files from this state-run program including records of medical care. Over 74,000 WC medical encounters resulted from 2959 work-related back injuries. Eleven percent received private care for musculoskeletal back pain within 90 days of work-related injury; this proportion increased with increasing lost days. Delay to physical therapy was more prevalent among those out of work longest. The proportion of claimants with care from both systems and from private utilization only increased after the first 90 days and, for the subset with at least one paid lost work day, after return to work. Examination of medical care through both systems versus solely in workers' compensation provides a more complete understanding of back injury care while also demonstrating complexity. Differences in outcomes based upon treatment shortly after injury are worthy of further exploration.
Employment and work-related issues in cancer survivors.
Mehnert, Anja
2011-02-01
Purpose of this systematic literature review was to identify current knowledge about employment in cancer survivors. Sixty-four studies met inclusion criteria that were original papers published between 01/2000 and 11/2009. Overall, 63.5% of cancer survivors (range 24-94%) returned to work. The mean duration of absence from work was 151 days. Factors significantly associated with a greater likelihood of being employed or return to work were perceived employer accommodation, flexible working arrangements, counseling, training and rehabilitation services, younger age and cancer sites of younger individuals, higher levels of education, male gender, less physical symptoms, lower length of sick leave and continuity of care. Cancer survivors had a significantly increased risk for unemployment, early retirement and were less likely to be re-employed. Between 26% and 53% of cancer survivors lost their job or quit working over a 72-month period post diagnosis. Between 23% and 75% of patients who lost their job were re-employed. A high proportion of patients experienced at least temporary changes in work schedules, work hours, wages and a decline in work ability compared to non-cancer groups.

To compare work-loss in RA patients starting their first biologic with high vs moderate disease activity. We identified all RA patients aged 20-63 years in the Swedish Biologics Register who started their first biologic 2007-09 with high disease activity (DAS28 >5.1; n = 868) or moderate disease activity (DAS28 3.2-5.1; n = 854). Work days lost, defined as sick leave and disability pension days from the Swedish Social Insurance Agency, were assessed over 5 years after first bio-start. We estimated between-group mean differences adjusted for age, sex, calendar year, education level, disease duration, comorbidities and work-loss the month before bio-start. During 5 years after anti-TNF start, mean monthly work days lost declined from 16.0 to 9.2 (42%; P < 0.001) in patients with high disease activity at baseline and from 12.0 to 7.2 (40%; P < 0.001) in patients with moderate disease activity, with no between-group difference (adjusted mean difference 0.81; 95% CI - 0.44, 2.05). Accumulated 5-year work-loss was, however, higher in the high activity group (724 vs 548 days; adjusted mean difference 70; 95% CI 20, 120), but after stratification on baseline disability pension status, no differences in accumulated work-loss were detected. Substantial work-loss was seen in both patients with high and patients with moderate disease activity at anti-TNF start, with a 5-year decline in mean monthly work days lost by ∼40% in both groups and no between-group difference. Accumulated work-loss over 5 years was higher in the high-activity group, which may be explained by differences in baseline disability pension status. © The Author 2015.

Squad management, injury and physical, tactical and technical match performance were investigated in a professional soccer team across five consecutive league seasons (2008-2013, 190 league games) with specific focus on a championship-winning season (2010/11). For each player, match participation and time-loss injuries were recorded, the latter prospectively diagnosed by the team's physician. Defending and attacking tactical and technical performance indicators investigated included ball possession and possession in opponents' half, passes, forward passes, completed passes and forward passes, crosses and completed crosses, goal attempts and goal attempts on target, successful final third entries, free-kicks and 50/50 duels won/lost. Physical performance measures included total distance and distance covered at high-speeds (≥19.1 km/h). Results showed that during the 2010/11 season, squad utilisation was lowest potentially owing to the observed lower match injury occurrence and working days lost to injury thereby increasing player availability. In 2010/11, the team won both its highest number of points and conceded its lowest number of goals especially over the second half of this season. The team also won its highest number of games directly via a goal from a substitute and scored and conceded a goal first on the highest and lowest number of occasions, respectively. While multivariate analysis of variance (MANOVA) detected a significant difference in some attacking and defensive performance indicators across the five seasons, these were generally not distinguishing factors in 2010/11. Similarly, univariate ANOVAs showed a significant difference in running distances covered across seasons, but the trend was for less activity in 2010/11.

Safe performance of oilfield service operations at unfamiliar customer installations requires service personnel that are highly trained and motivated. When such operations are made in over sixty countries with an independent, multi-cultural work force, an additional level of difficulty in achieving an improved level of HSE (Health, Safety & Environment) performance is introduced. Recognizing these challenges, one company set out in 1989 to implement a comprehensive HSE management system suited to this environment. The system, described here, was launched with total commitment and participation of all levels of management and was designed to empower the work force rather than forcemore » them into compliance. This included a realignment of management priorities to give HSE a primary place along with other management responsibilities. One central theme of the system is a single standard applied to all HSE actions, throughout the world and at all levels of the Company. Thus, for example, all employees including all managers go through the same basic HSE training courses on a regular basis. After six years, a cultural change has taken place, along with a notable reduction in both accident frequency and severity, measured in terms of lost workdays. This reduction in lost workdays is an easily quantifiable cost saving which by far outweighs the total cost of the HSE system implementation. While the HSE management system was designed to specifically meet the needs of the company, the techniques used closely parallel those of Total Quality Management (TQM), which, in the last years, has gained momentum as a {open_quotes}new paradigm{close_quotes} in the HSE field. In this company`s experience, a common sense application of sound management to the HSE process has led to a TQM system.« less

Compensation in higher education is an inclusive term, since all the benefits associated with teaching, research, work with people, and work with knowledge might be included. But in terms of purchasing power it appears that compensation for work in higher education has lost ground against inflation. In contrast, wage and salary earners in many…

Objectives. This study collected and evaluated data on the costs of outpatient medical care and family burden associated with osteoporosis-related fracture rehabilitation following hospital discharge in China. Materials and Methods. Data were collected using a patient questionnaire from osteoporosis-related fracture patients (N = 123) who aged 50 years and older who were discharged between January 2011 and January 2013 from 3 large hospitals in China. The survey captured posthospital discharge direct medical costs, indirect medical costs, lost work time for caregivers, and patient ambulatory status. Results. Hip fracture was the most frequent fracture site (62.6%), followed by vertebral fracture (34.2%). The mean direct medical care costs per patient totaled 3,910¥, while mean indirect medical costs totaled 743¥. Lost work time for unpaid family caregivers was 16.4 days, resulting in an average lost income of 3,233¥. The average posthospital direct medical cost, indirect medical cost, and caregiver lost income associated with a fracture patient totaled 7,886¥. Patients' ambulatory status was negatively impacted following fracture. Conclusions. Significant time and cost of care are placed on patients and caregivers during rehabilitation after discharge for osteoporotic fracture. It is important to evaluate the role and responsibility for creating the growing and inequitable burden placed on patients and caregivers following osteoporotic fracture. PMID:26221563

Little is known about the effects of adult attention deficit hyperactivity disorder (ADHD) on work performance or accidents-injuries.MethodA survey was administered in 2005 and 2006 to employees of a large manufacturing firm to assess the prevalence and correlates of adult ADHD. Respondents (4,140 in 2005, 4,423 in 2006, including 2,656 in both surveys) represented 35-38% of the workforce. ADHD was assessed with the World Health Organization (WHO) Adult ADHD Self-Report Scale (ASRS), a validated screening scale for DSM-IV adult ADHD. Sickness absence, work performance and workplace accidents-injuries were assessed with the WHO Health and Work Performance Questionnaire (HPQ). The estimated current prevalence (standard error) of DSM-IV ADHD was 1.9% (0.4). ADHD was associated with a 4-5% reduction in work performance (chi12=9.1, p=0.001), a 2.1 relative-odds of sickness absence (chi12=6.2, p=0.013), and a 2.0 relative-odds of workplace accidents-injuries (chi12=5.1, p=0.024). The human capital value (standard error) of the lost work performance associated with ADHD totaled USD 4,336 (676) per worker with ADHD in the year before interview. No data were available to monetize other workplace costs of accidents-injuries (e.g. destruction of equipment). Only a small minority of workers with ADHD were in treatment. Adult ADHD is a significantly impairing condition among workers. Given the low rate of treatment and high human capital costs, in conjunction with evidence from controlled trials that treatment can reduce ADHD-related impairments, ADHD would seem to be a good candidate for workplace trials that evaluate treatment cost-effectiveness from the employer's perspective.

Nurses have one of the highest rates of work-related musculoskeletal injury of any profession. Over the past 30 years, efforts to reduce work-related musculoskeletal disorders in nurses have been largely unsuccessful. The primary goal of this program was to create safer working environments for nursing staff who provide direct patient care. Our first objective was to design and implement a multifaceted program that successfully integrated evidence-based practice, technology, and safety improvement. The second objective was to evaluate the impact of the program on injury rate, lost and modified work days, job satisfaction, self-reported unsafe patient handling acts, level of support for program, staff and patient acceptance, program effectiveness, costs, and return on investment. The intervention included six program elements: (1) Ergonomic Assessment Protocol, (2) Patient Handling Assessment Criteria and Decision Algorithms, (3) Peer Leader role, "Back Injury Resource Nurses", (4) State-of-the-art Equipment, (5) After Action Reviews, and (6) No Lift Policy. A pre-/post design without a control group was used to evaluate the effectiveness of a patient care ergonomics program on 23 high risk units (19 nursing home care units and 4 spinal cord injury units) in 7 facilities. Injury rates, lost work days, modified work days, job satisfaction, staff , and patient acceptance, program effectiveness, and program costs/savings were compared over two nine month periods: pre-intervention (May 2001-January 2002) and post-intervention (March 2002-November 2002). Data were collected prospectively through surveys, weekly process logs, injury logs, and cost logs. The program elements resulted in a statistically significant decrease in the rate of musculoskeletal injuries as well as the number of modified duty days taken per injury. While the total number of lost workdays decreased by 18% post-intervention, this difference was not statistically significant. There were statistically significant increases in two subscales of job satisfaction: professional status and tasks requirements. Self-reports by nursing staff revealed a statistically significant decrease in the number of 'unsafe' patient handling practices performed daily. Nurses ranked program elements they deemed to be "extremely effective": equipment was rated as most effective (96%), followed by No Lift Policy (68%), peer leader education program (66%), ergonomic assessment protocol (59%), patient handling assessment criteria and decision algorithms (55%), and lastly after action reviews (41%). Perceived support and interest for the program started at a high level for managers and nursing staff and remained very high throughout the program implementation. Patient acceptance was moderate when the program started but increased to very high by the end of the program. Although the ease and success of program implementation initially varied between and within the facilities, after six months there was strong evidence of support at all levels. The initial capital investment for patient handling equipment was recovered in approximately 3.75 years based on annual post-intervention savings of over $200,000/year in workers' compensation expenses and cost savings associated with reduced lost and modified work days and worker compensation. This multi-faceted program resulted in an overall lower injury rate, fewer modified duty days taken per injury, and significant cost savings. The program was well accepted by patients, nursing staff, and administrators. Given the significant increases in two job satisfaction subscales (professional status and task requirements), it is possible that nurse recruitment and retention could be positively impacted.
Reducing failures of working memory with performance feedback.
Adam, Kirsten C S; Vogel, Edward K

Fluctuations in attentional control can lead to failures of working memory (WM), in which the subject is no better than chance at reporting items from a recent display. In three experiments, we used a whole-report measure of visual WM to examine the impact of feedback on the rate of failures. In each experiment, subjects remembered an array of colored items across a blank delay, and then reported the identity of items using a whole-report procedure. In Experiment 1, we gave subjects simple feedback about the number of items they correctly identified at the end of each trial. In Experiment 2, we gave subjects additional information about the cumulative number of items correctly identified within each block. Finally, in Experiment 3, we gave subjects weighted feedback in which poor trials resulted in lost points and consistent successful performance received "streak" points. Surprisingly, simple feedback (Exp. 1) was ineffective at improving average performance or decreasing the rate of poor-performance trials. Simple cumulative feedback (Exp. 2) modestly decreased poor-performance trials (by 7 %). Weighted feedback produced the greatest benefits, decreasing the frequency of poor-performance trials by 28 % relative to baseline performance. This set of results demonstrates the usefulness of whole-report WM measures for investigating the effects of feedback on WM performance. Further, we showed that only a feedback structure that specifically discouraged lapses using negative feedback led to large reductions in WM failures.

Objective: To correlate the types of skatepark-related injuries with medical expenses and the monetary effects of time missed from work or school. Design: Prospective case series and survey with repeat measures over 1 year. Setting: Southern California Level I Trauma Center and Emergency Department. Participants: Subjects age 7 years or older who sustained an injury at a local skatepark and treated in the emergency department were included in the study. Methods: A skatepark-related injury survey was conducted at the time of the subject’s emergency department evaluation.Thereafter, subjects were contacted by telephone at 1 week and 1, 3, 6, 9 and 12 months post-injury to assess the extent of ongoing follow-up medical care, time lost from work and school for both the subject and parents, and the degree of self-reported disability. The costs of injury were estimated using accepted econometric methods. The cost of medical care and lost household productivity were estimated using data specific to the nature of the injury and the body part injured. Results: Skatepark-related injuries resulted in a mean loss of 1.1 school days and 5.5 work days to the subject and family.The mean total injury costs were $3,167, of which 64% were medical costs and 28% were wages lost by the subject and family. Costs were much greater for subjects aged 26 years and older than for younger subjects and for those with more severe injuries than for less severe injuries. Conclusion: Skatepark injuries resulted in substantial medical costs and lost wages. Injured skatepark users 26 years and older and those with more severe injuries had the highest cost. PMID:18056022
Universal recovery map for approximate Markov chains.
Sutter, David; Fawzi, Omar; Renner, Renato
2016-02-01
A central question in quantum information theory is to determine how well lost information can be reconstructed. Crucially, the corresponding recovery operation should perform well without knowing the information to be reconstructed. In this work, we show that the quantum conditional mutual information measures the performance of such recovery operations. More precisely, we prove that the conditional mutual information I ( A : C | B ) of a tripartite quantum state ρ ABC can be bounded from below by its distance to the closest recovered state [Formula: see text], where the C -part is reconstructed from the B -part only and the recovery map [Formula: see text] merely depends on ρ BC . One particular application of this result implies the equivalence between two different approaches to define topological order in quantum systems.

Background Small-scale community health worker (CHW) programs provide basic health services and strengthen health systems in resource-poor settings. This paper focuses on improving CHW performance by providing individual feedback to CHWs working with an mHealth program to address malnutrition in children younger than 5 years. Objective The paper aims to evaluate the immediate and retention effects of providing performance feedback and supportive supervision on CHW motivation and performance for CHWs working with an mHealth platform to reduce malnutrition in five districts of Madhya Pradesh, India. We expected a positive impact on CHW performance for the indicator they received feedback on. Performance on indicators the CHW did not receive feedback on was not expected to change. Methods In a randomized controlled trial, 60 CHWs were randomized into three treatment groups based on overall baseline performance ranks to achieve balanced treatment groups. Data for each treatment indicator were analyzed with the other two treatments acting as the control. In total, 10 CHWs were lost to follow-up. There were three performance indicators: case activity, form submissions, and duration of counseling. Each group received weekly calls to provide performance targets and discuss their performance on the specific indicator they were allocated to as well as any challenges or technical issues faced during the week for a 6-week period. Data were collected for a further 4 weeks to assess intertemporal sustained effects of the intervention. Results We found positive and significant impacts on duration of counseling, whereas case activity and number of form submissions did not show significant improvements as a result of the intervention. We found a moderate to large effect (Glass’s delta=0.97, P=.004) of providing performance feedback on counseling times in the initial 6 weeks. These effects were sustained in the postintervention period (Glass’s delta=1.69, P<.001). The counseling times decreased slightly from the intervention to postintervention period by 2.14 minutes (P=.01). Case activity improved for all CHWs after the intervention. We also performed the analysis by replacing the CHWs lost to follow-up with those in their treatment groups with the closest ranks in baseline performance and found similar results. Conclusions Calls providing performance feedback are effective in improving CHW motivation and performance. Providing feedback had a positive effect on performance in the case of duration of counseling. The results suggest that difficulty in achieving the performance target can affect results of performance feedback. Regardless of the performance information disclosed, calls can improve performance due to elements of supportive supervision included in the calls encouraging CHW motivation. PMID:27927607

Recent labor economics studies in the United States and Canada have demonstrated that occupational injuries and illnesses often lead to substantial lost earnings for workers and their families. Other studies have shown substantial long-term lost earnings attributable to large-scale layoffs, where no health impairment has taken place. This article uses evidence from these and other studies of apparently different situations to draw inferences about how managers' actions and public policy choices can affect the costs of occupational injuries and illnesses. Although primary prevention remains the policy of choice, reduction in the impact of workplace injuries and illnesses can decrease the costs of these events and can provide substantial benefits. This article proposes two hypotheses and discusses the evidence for each: (a) Loss of the job held at the onset of illness or injury increases time off work and exacerbates workers' lost earnings. (b) Workers' losses may be substantially reduced by policies that encourage employers to rehire people recovering from or disabled by workplace injuries and illnesses.

Thermal energy storage (TES) device that uses phase change material (PCM) in the field of indirect solar drying is economical due to its energy storage characteristics. In this work, a low-temperature latent heat TES device has been numerically analyzed for the application of solar drying of agricultural products in an indirect type solar dryer. Paraffin wax is used as a PCM material. The study has been performed on a single set of concentric tubes which consist of an inner copper tube and an outer plastic tube. A 2D geometry is created and computational fluid dynamics (CFD) simulations are performed using ANSYS Fluent 2015. The hot air coming from solar collector enters the copper tube and then the drying chamber to dry the sample. PCM material is placed in the outer plastic tube. It was found that the drying process can be continued up to 10.00 pm without further source of heating. At a given time, the melting fraction is increased during the heating process and solidification factor is increased during the cooling process while increasing the air flow velocities from 1 to 4 m/s, but 1 m/s is good for maintaining outlet temperature of air (T oa ) for a long time. Heat lost and gained by air was estimated. It was found that air flow velocity influenced the heat lost and gain by air.

Purpose The Asia-Pacific Burden of Respiratory Diseases (APBORD) study is a cross-sectional, observational one which has used a standard protocol to examine the disease and economic burden of allergic rhinitis (AR), asthma, chronic obstructive pulmonary disorder (COPD), and rhinosinusitis across the Asia-Pacific region. Here, we report on symptoms, healthcare resource use, work impairment, and associated costs in Korea. Methods Consecutive participants aged ≥18 years with a primary diagnosis of asthma, AR, COPD, or rhinosinusitis were enrolled. Participants and their treating physician completed a survey detailing respiratory symptoms, healthcare resource use, and work productivity and activity impairment. Costs included direct medical cost and indirect cost associated with lost work productivity. Results The study enrolled 999 patients. Patients were often diagnosed with multiple respiratory disorders (42.8%), with asthma/AR and AR/rhinosinusitis the most frequently diagnosed combinations. Cough or coughing up phlegm was the primary reason for the medical visit in patients with a primary diagnosis of asthma and COPD, whereas nasal symptoms (watery runny nose, blocked nose, and congestion) were the main reasons in those with AR and rhinosinusitis. The mean annual cost for patients with a respiratory disease was US$8,853 (SD 11,245) per patient. Lost productivity due to presenteeism was the biggest contributor to costs. Conclusions Respiratory disease has a significant impact on disease burden in Korea. Treatment strategies for preventing lost work productivity could greatly reduce the economic burden of respiratory disease. PMID:27582404

To determine the effectiveness of an office-based multimodal hand hygiene improvement intervention in reducing self-reported communicable infections and work-related absence. A randomized cluster trial including an electronic training video, hand sanitizer, and educational posters (n = 131, intervention; n = 193, control). Primary outcomes include (1) self-reported acute respiratory infections (ARIs)/influenza-like illness (ILI) and/or gastrointestinal (GI) infections during the prior 30 days; and (2) related lost work days. Incidence rate ratios calculated using generalized linear mixed models with a Poisson distribution, adjusted for confounders and random cluster effects. A 31% relative reduction in self-reported combined ARI-ILI/GI infections (incidence rate ratio: 0.69; 95% confidence interval, 0.49 to 0.98). A 21% nonsignificant relative reduction in lost work days. An office-based multimodal hand hygiene improvement intervention demonstrated a substantive reduction in self-reported combined ARI-ILI/GI infections.

This study is based on a survey conducted in Hong Kong, Indonesia, Korea, Malaysia, the Philippines, Singapore, Sri Lanka and Thailand on occupational injuries during the years 1975-1980. The number of work accidents have risen rapidly during this period in all of the 8 countries studied. In the case of Thailand, the total number of work injuries increased four fold from 1975-1978, whereas, in Singapore it has almost doubled in 6 years. The number of permanent disablement nearly trebled in Korea, and the Philippines for the year 1967-1980. The largest percentage of accidents are lost-time injuries in all of the 8 countries. Thailand had a three fold increase in lost-time injuries whilst in Hong Kong the figure doubled. Six out of the 8 countries indicated that the building construction industry had the largest number of fatal accidents, followed by the manufacturing industry.

Employer model of workplace impacts of anti-TNF therapy for rheumatoid arthritis.
Birnbaum, Howard; Pike, Crystal; Kaufman, Rebecca; Cifaldi, Mary
2009-10-01
Rheumatoid arthritis (RA) greatly affects patients' abilities to perform work, which can translate into substantial employer costs. We developed a customizable model that allows employers to calculate workplace impacts of RA therapies in employees with RA. Costs of medical leave (absenteeism)/disability, reduced productivity, job turnover, and work-equipment adaptations for employees with RA were calculated. Costs of the tumor necrosis factor antagonist adalimumab were compared with those of other RA treatments. Default parameters were based on literature, clinical trials, government sources, and employers' data. Annual per-employee workplace cost was $9071 for adalimumab versus $16,335 for other RA therapies. Costs included reduced productivity (57%), absenteeism/disability (21%), and job turnover (21%). RA imposes a large financial burden on employers, predominantly owing to lost productivity. When compared with other RA therapies, adalimumab substantially reduced employers' costs.
The Cost of Smoking in California.

The economic impact of smoking, including healthcare costs and the value of lost productivity due to illness and mortality, was estimated for California for 2009. Smoking-attributable healthcare costs were estimated using a series of econometric models that estimate expenditures for hospital care, ambulatory care, prescriptions, home health care, and nursing home care. Lost productivity due to illness was estimated using an econometric model predicting how smoking status affects the number of days lost from work or other activities. The value of lives lost from premature mortality due to smoking was estimated using an epidemiological approach. Almost 4 million Californians still smoke, including 146 000 adolescents. The cost of smoking in 2009 totaled $18.1 billion, including $9.8 billion in healthcare costs, $1.4 billion in lost productivity from illness, and $6.8 billion in lost productivity from premature mortality. This amounts to $487 per California resident and $4603 per smoker. Costs were greater for men than for women. Hospital costs comprised 44% of healthcare costs. Despite extensive efforts at tobacco control in California, healthcare and lost productivity costs attributable to smoking remain high. Compared to costs for 1999, the total cost was 15% greater in 2009. However, after adjusting for inflation, real costs have fallen by 13% over the past decade, indicating that efforts have been successful in reducing the economic burden of smoking in the state. © The Author 2015.

Psoriasis causes work productivity impairment that increases with disease severity. Whether differential treatment efficacy translates into differential indirect cost savings is unknown. To assess work hours lost and indirect costs associated with secukinumab versus ustekinumab and etanercept in the United Kingdom (UK). This was a post hoc analysis of work impairment data collected in the CLEAR study (secukinumab vs. ustekinumab) and applied to the FIXTURE study (secukinumab vs. etanercept). Weighted weekly and annual average indirect costs per patient per treatment were calculated from (1) overall work impairment derived from Work Productivity and Activity Impairment data collected in CLEAR at 16 and 52 weeks by Psoriasis Area and Severity Index (PASI) response level; (2) weekly/annual work productivity loss by PASI response level; (3) weekly and annual indirect costs by PASI response level, based on hours of work productivity loss; and (4) weighted average indirect costs for each treatment. In the primary analysis, work impairment data for employed patients in CLEAR at Week 16 were used to compare secukinumab and ustekinumab. Secondary analyses were conducted at different timepoints and with patient cohorts, including FIXTURE. In CLEAR, 452 patients (67%) were employed at baseline. At Week 16, percentages of weekly work impairment/mean hours lost decreased with higher PASI: PASI <50: 22.8%/7.60 hours; PASI 50-74: 13.3%/4.45 hours; PASI 75-89: 6.4%/2.14 hours; PASI ≥90: 4.9%/1.65 hours. Weighted mean weekly/annual work hours lost were significantly lower for secukinumab than ustekinumab (1.96/102.51 vs. 2.40/125.12; P=0.0006). Results were consistent for secukinumab versus etanercept (2.29/119.67 vs. 3.59/187.17; Ρ<0.0001). Average annual indirect cost savings with secukinumab were £355 versus ustekinumab and £1,061 versus etanercept. Results at 52 weeks were similar. Secukinumab significantly reduced work impairment and associated indirect costs of psoriasis compared with ustekinumab and etanercept at Week 16 through 52 in the UK.

The author puts forth the hypothesis that mental phenomena are connected with thermodynamic properties of large neural network. A model of the subject with reflexion and capable for meditation is constructed. The processes of reflexion and meditation are presented as the sequence of heat engines. Each subsequent engine compensates for the imperfectness of the preceding engine by performing work equal to the lost available work of the preceding one. The sequence of heat engines is regarded as a chain of the subject's mental images of the self. Each engine can be interpreted as an image of the self that the engine next to it has, and the work performed by engines as the emotions that the subject and his images are experiencing. Two types of meditation are analyzed: The dissolution in nothingness and union with the Absolute. In the first type, the initial engine is the one that yields heat to the coldest reservoir, and in the second type, the initial engine is the one that takes heat from the hottest reservoir. The main concepts of thermodynamics are reviewed in relation to the process of human reflexion. Copyright © 2017 Elsevier Ltd. All rights reserved.

Terra-Berns, Mary
The Albeni Falls Interagency Work Group continued to actively engage in implementing wildlife mitigation actions in 2002. Regular Work Group meetings were held to discuss budget concerns affecting the Albeni Falls Wildlife Mitigation Program, to present potential acquisition projects, and to discuss and evaluate other issues affecting the Work Group and Project. Work Group members protected 1,386.29 acres of wildlife habitat in 2002. To date, the Albeni Falls project has protected approximately 5,914.31 acres of wildlife habitat. About 21% of the total wildlife habitat lost has been mitigated. Administrative activities have increased as more properties are purchased and continue tomore » center on restoration, operation and maintenance, and monitoring. In 2001, Work Group members focused on development of a monitoring and evaluation program as well as completion of site-specific management plans. This year the Work Group began implementation of the monitoring and evaluation program performing population and plant surveys, data evaluation and storage, and map development as well as developing management plans. Assuming that the current BPA budget restrictions will be lifted in the near future, the Work Group expects to increase mitigation properties this coming year with several potential projects.« less
Impact of paid work on the academic performance of nursing students
García-Vargas, Mery Constanza; Cortés-Castell, Ernesto
2016-01-01
Background. Little research exists on the impact of paid work on academic performance of students of health sciences. No research exists on this subject for students in Colombia. Objectives. This paper seeks to analyze the impact of paid work on academic performance among nursing students. Design, settings and participants: cross-sectional research, involving 430 of nursing students from the National University of Colombia (N = 566). Methods. Variables analyzed: sex, age, work activity, attendance, current semester, degree subjects studied and unavailable, lost credits, grades during the second semester of 2013, and delayed semesters. Subgroups analyzed: (i) according to labor activity: do not work, work up to 20 h and work more than 20 h per week; (ii) Grade point average: failing is considered as less than 3.0 and passing 3.0 or above out of 5.0. Percentage of delayed semesters were calculated. Qualitative and quantitative variables were analyzed for groups by work activity. The percentage and probability of students getting a grade point average less than 3.0 and delaying semesters were calculated by multivariate logistic regression. Results. A total of 219 of the students work (50.9%), the main reason is socioeconomic, of which 99 (45.2%) work more than 20 h per week and have an increased risk of failing, which is higher in the first semester. They also get lower grades, lose more credits and take longer to finish the degree. The logistic bivariate regressions of success (grade point average, credits gained, courses gained and not having delayed semesters) reduce with work, above all in those who work more than 20 h per week and increase as the number of semesters completed increases, independent of sex. Conclusion. A high percentage of nursing students work more than 20 h per week. The compatibility of paid work with studies in university nursing students has a negative impact on academic performance, more so when they work more than 20 h per week. This negative impact diminishes as the student completes semesters, irrespective of the sex of the students. PMID:27069788

When performing Computed Tomographic (CT) image reconstruction on digital subtraction angiography (DSA) projections, loss of vessel contrast has been observed behind highly attenuating anatomy, such as dental implants and large contrast filled aneurysms. Because this typically occurs only in a limited range of projection angles, the observed contrast time course can potentially be altered. In this work, we have developed a model for acquiring DSA projections that models both the polychromatic nature of the x-ray spectrum and the x-ray scattering interactions to investigate this problem. In our simulation framework, scatter and beam hardening contributions to vessel dropout can be analyzed separately. We constructed digital phantoms with large clearly defined regions containing iodine contrast, bone, soft issue, titanium (dental implants) or combinations of these materials. As the regions containing the materials were large and rectangular, when the phantoms were forward projected, the projections contained uniform regions of interest (ROI) and enabled accurate vessel dropout analysis. Two phantom models were used, one to model the case of a vessel behind a large contrast filled aneurysm and the other to model a vessel behind a dental implant. Cases in which both beam hardening and scatter were turned off, only scatter was turned on, only beam hardening was turned on, and both scatter and beam hardening were turned on, were simulated for both phantom models. The analysis of this data showed that the contrast degradation is primarily due to scatter. When analyzing the aneurysm case, 90.25% of the vessel contrast was lost in the polychromatic scatter image, however only 50.5% of the vessel contrast was lost in the beam hardening only image. When analyzing the teeth case, 44.2% of the vessel contrast was lost in the polychromatic scatter image and only 26.2% of the vessel contrast was lost in the beam hardening only image.

Costs of tobacco-related disease can be useful evidence to support tobacco control. In Hong Kong we now have locally derived data on the risks of smoking, including passive smoking. To estimate the health-related costs of tobacco from both active and passive smoking. Using local data, we estimated active and passive smoking-attributable mortality, hospital admissions, outpatient, emergency and general practitioner visits for adults and children, use of nursing homes and domestic help, time lost from work due to illness and premature mortality in the productive years. Morbidity risk data were used where possible but otherwise estimates based on mortality risks were used. Utilisation was valued at unit costs or from survey data. Work time lost was valued at the median wage and an additional costing included a value of USD 1.3 million for a life lost. In the Hong Kong population of 6.5 million in 1998, the annual value of direct medical costs, long term care and productivity loss was USD 532 million for active smoking and USD 156 million for passive smoking; passive smoking accounted for 23% of the total costs. Adding the value of attributable lives lost brought the annual cost to USD 9.4 billion. The health costs of tobacco use are high and represent a net loss to society. Passive smoking increases these costs by at least a quarter. This quantification of the costs of tobacco provides strong motivation for legislative action on smoke-free areas in the Asia Pacific Region and elsewhere.

A mathematical model was developed for estimating the net present value (NPV) of the cash flow resulting from an investment in an intervention to prevent occupational low back pain (LBP). It combines biomechanics, epidemiology, and finance to give an integrated tool for a firm to use to estimate the investment worthiness of an intervention based on a biomechanical analysis of working postures and hand loads. The model can be used by an ergonomist to estimate the investment worthiness of a proposed intervention. The analysis would begin with a biomechanical evaluation of the current job design and post-intervention job. Economic factors such as hourly labor cost, overhead, workers' compensation costs of LBP claims, and discount rate are combined with the biomechanical analysis to estimate the investment worthiness of the proposed intervention. While this model is limited to low back pain, the simulation framework could be applied to other musculoskeletal disorders. The model uses Monte Carlo simulation to compute the statistical distribution of NPV, and it uses a discrete event simulation paradigm based on four states: (1) working and no history of lost time due to LBP, (2) working and history of lost time due to LBP, (3) lost time due to LBP, and (4) leave job. Probabilities of transitions are based on an extensive review of the epidemiologic review of the low back pain literature. An example is presented.

To describe the Migraine Adaptive Cost-Effectiveness Model in the context of an analysis of a simulated population of Canadian patients with migraine. The high prevalence of migraine and its substantial impact on patients' ability to function normally present a significant economic burden to society. In light of the recent availability of improved pharmaceutical treatments, a model was developed to assess their economic impact. The Migraine Adaptive Cost-Effectiveness Model incorporates the costs of time lost from both work and nonwork activities, as well as medical resource and medication use. Using Monte Carlo techniques, the model simulates the experience of a population of patients with migraine over the course of 1 year. As an example, analyses of a Canadian population were carried out using data from a multinational trial, surveys, national statistics, and the available literature. Using customary therapy, mean productivity losses (amounting to 84 hours of paid work time, 48 hours of unpaid work time, and 113 hours of leisure time lost) were estimated to cost $1949 (in 1997 Canadian dollars) per patient, with medical expenditures adding an average of $280 to the cost of illness. With customary treatment patterns, the costs of migraine associated with reduced functional capacity are substantial. The migraine model represents a flexible tool for the economic evaluation of different migraine treatments in various populations.

To project the number of older workers with lost productive life years (PLYs) due to chronic disease and resultant lost income; and lost taxes and increased welfare payments from 2015 to 2030. Using a microsimulation model, Health&WealthMOD2030, the costs of chronic disease in Australians aged 45-64 were projected to 2030. The model integrates household survey data from the Australian Bureau of Statistics Surveys of Disability, Ageing and Carers (SDACs) 2003 and 2009, output from long-standing microsimulation models (STINMOD (Static Incomes Model) and APPSIM (Australian Population and Policy Simulation Model)) used by various government departments, population and labour force growth data from Treasury, and disease trends data from the Australian Burden of Disease and Injury Study (2003). Respondents aged 45-64 years in the SDACs 2003 and 2009 formed the base population. Lost PLYs due to chronic disease; resultant lost income, lost taxes and increased welfare payments in 2015, 2020, 2025 and 2030. We projected 380 000 (6.4%) people aged 45-64 years with lost PLYs in 2015, increasing to 462 000 (6.5%) in 2030-a 22% increase in absolute numbers. Those with lost PLYs experience the largest reduction in income than any other group in each year compared to those employed full time without a chronic disease, and this income gap widens over time. The total economic loss due to lost PLYs consisted of lost income modelled at $A12.6 billion in 2015, increasing to $A20.5 billion in 2030-a 62.7% increase. Additional costs to the government consisted of increased welfare payments at $A6.2 billion in 2015, increasing to $A7.3 billion in 2030-a 17.7% increase; and a loss of $A3.1 billion in taxes in 2015, increasing to $A4.7 billion in 2030-a growth of 51.6%.

Informal care plays an important role in the overall care for people with cancer. This study estimates lost productivity and informal caregiving and associated costs among partner caregivers of localized prostate cancer patients within 1 year after diagnosis. We applied data from the Family and Cancer Therapy Selection study, a three-wave self-administered survey among patients diagnosed with localized prostate cancer and their partner caregivers in multiple clinics in the USA. Time spent was measured by the sum of working hours lost, informal caregiving hours performed, and hours spent on household chores. The national median income for women 55 years or older was used to calculate costs associated with the time spent using the opportunity cost method. Descriptive and bivariate analyses were conducted. The average working hours decreased from 14.0 h/week (SD = 17.6) to 10.9 h/week (SD = 15.9), without a significant change in responsibility/intensity at work. The mean annual time spent on informal caregiving and household chores was 65.9 h/year (SD = 172.4) and 76.2 h/year (SD = 193.3), respectively. The mean annual economic burden among partner caregivers was US$6,063 (range US$571-US$47,105) in 2009 dollars accounted for by a mean of 276.2 h (range 26-2,146) in the study sample. The time spent on informal caregiving and household chores varied by patient and caregiver characteristics. Pilot estimates on non-medical economic burden among partner caregivers (spouses) during the initial phase of the treatment provide important information for comprehensive estimation of disease burden and can be used in cost-effectiveness analyses of prostate cancer interventions.
Vaccination versus treatment of influenza in working adults: a cost-effectiveness analysis.
Rothberg, Michael B; Rose, David N
2005-01-01
To determine the cost-effectiveness of influenza vaccination, antiviral therapy, or no intervention for healthy working adults, accounting for annual variation in vaccine efficacy. We conducted a cost-effectiveness analysis based on published clinical trials of influenza vaccine and antiviral drugs, incorporating 10 years of surveillance data from the World Health Organization. We modeled influenza vaccination, treatment of influenza-like illness with antiviral drugs, or both, as compared with no intervention, targeting healthy working adults under age 50 years in the general community or workplace. Outcomes included costs, illness days, and quality-adjusted days gained. In the base case analysis, the majority of costs incurred for all strategies were related to lost productivity from influenza illness. The least expensive strategy varied from year to year. For the 10-year period, antiviral therapy without vaccination was associated with the lowest overall costs (234 US dollars per person per year). Annual vaccination cost was 239 US dollars per person, and was associated with 0.0409 quality-adjusted days saved, for a marginal cost-effectiveness ratio of 113 US dollars per quality-adjusted day gained or 41,000 US dollars per quality-adjusted life-year saved compared with antiviral therapy. No intervention was the most expensive and least effective option. In sensitivity analyses, lower vaccination costs, higher annual probabilities of influenza, and higher numbers of workdays lost to influenza made vaccination more cost-effective than treatment. If vaccination cost was less than 16 US dollars or time lost from work exceeded 2.4 days per episode of influenza, then vaccination was cost saving compared with all other strategies. Influenza vaccination for healthy working adults is reasonable economically, and under certain circumstances is cost saving. Antiviral therapy is consistently cost saving.
Dissociable loss of the representations in visual short-term memory.
Li, Jie
2016-01-01
The present study investigated in what manner the information in visual short-term memory (VSTM) is lost. Participants memorized four items, one of which was given higher priority later by a retro-cue. Then participants were required to detect a possible change, which could be either a large or small change, occurred to one of the items. The results showed that the detection performance for the small change of the uncued items was poorer than the cued item, yet large change that occurred to all four memory items could be detected perfectly, indicating that the uncued representations lost some detailed information yet still had some basic features retained in VSTM. The present study suggests that after being encoded into VSTM, the information is not lost in an object-based manner; rather, features of an item are still dissociable, so that they can be lost separately.
The chemical evolution of Dwarf Galaxies with galactic winds - the role of mass and gas distribution
NASA Astrophysics Data System (ADS)
Hensler, Gerhard; Recchi, Simone
2015-08-01
Energetic feedback from Supernovae and stellar winds can drive galactic winds. Dwarf galaxies (DGs), due to their shallower potential wells, are assumed to be more vulnera-ble to these energetic processes. Metal loss through galactic winds is also commonly invoked to explain the low metal content of DGs.Our main aim in this presentation is to show that galactic mass cannot be the only pa-rameter determining the fraction of metals lost by a galaxy. In particular, the distribution of gas must play an equally important role. We perform 2-D chemo-dynamical simula-tions of galaxies characterized by different gas distributions, masses and gas fractions. The gas distribution can change the fraction of lost metals through galactic winds by up to one order of magnitude. In particular, disk-like galaxies tend to lose metals more easily than roundish ones. Consequently, also the final element abundances attained by models with the same mass but with different gas distributions can vary by up to one dex. Confirming previous studies, we also show that the fate of gas and freshly pro-duced metals strongly depends on the mass of the galaxy. Smaller galaxies (with shal-lower potential wells) more easily develop large-scale outflows; therefore, the fraction of lost metals tends to be higher.Another important issue is that the invoked mechanism to transform central cusps to cored dark-matter distributions by baryon loss due to strong galactic winds cannot work in general, must be critically tested, and should be clearly discernible by the chemical evolution of DGs.

Health economic evaluations (i.e. cost-effectiveness appraisal of an intervention) are useful aids for decision makers responsible for the allocation of scarce healthcare resources. The relevance of including health-related productivity costs (or benefits) in these evaluations is increasingly recognized and, as such, reliable and valid instruments to quantify productivity costs are needed. Over the years, a number of work productivity instruments have emerged in the literature, along with a growing body of psychometric evidence. The overall aim of this paper is to provide a review of available instruments with potential for estimating health-related productivity costs. This included the Health and Labor Questionnaire, Health and Work Performance Questionnaire, Health-Related Productivity Questionnaire Diary, Productivity and Disease Questionnaire, Quantity and Quality method, Stanford Presenteeism Scale 13, Valuation of Lost Productivity, Work and Health Interview, Work Limitations Questionnaire, Work Productivity and Activity Impairment Questionnaire, and Work Productivity Short Inventory. Critical discussions on the instruments' overall strengths and limitations, applicability for health economic evaluations, as well as the methodological quality of existing psychometric evidence were provided. Lastly, a set of reflective questions were proposed for users to consider when selecting an instrument for health economic evaluations.
Performance tests of a two phase ejector

The ejector expansion refrigeration cycle is a modified vapor compression cycle in which a two phase ejector is used to recover a portion of the work otherwise lost in the expansion valve. The ejector improves cycle performance by increasing compressor inlet pressure and by lowering the quality of liquid entering the evaporator. Theoretically, a cooling COP improvement of approximately 23% is achievable for a typical refrigerating cycle and an ideal ejector. If the ejector performed as well as typical single phase ejectors an improvement of 12% could be achieved. Previous tests have demonstrated a smaller 3.7% improvement; the difference ismore » in the poor performance of the two phase ejector. The purpose of this research is to understand the operating characteristics of the two phase ejector and to devise design improvements. A two phase ejector test rig has been constructed and tested. Preliminary data show performance superior to previously tested two phase ejectors, but still inferior to single phase ejectors. Ejector performance corresponds to refrigeration cycle COP improvements ranging from 3.9% to 7.6%.« less

The mining industry is associated with high levels of accidents, injuries and illnesses. Lost-time injuries are useful measures of health and safety in mines, and the effectiveness of its safety programmes. To identify the type of lost-time injuries in the US mining workforce and to examine predictors of these occupational injuries. Primary papers on lost-time injuries in the US mining sector were identified through a literature search in eight health, geology and mining databases, using a systematic review protocol tailored to each database. The Critical Appraisal Skills Programme (CASP), Framework of Quality Assurance for Administrative Data Source and the Cochrane Collaboration 'Risk of bias' assessment tools were used to assess study quality. A total of 1736 articles were retrieved before duplicates were removed. Fifteen articles were ultimately included with a CASP mean score of 6.33 (SD 0.62) out of 10. Predictors of lost-time injuries included slips and falls, electric injuries, use of mining equipment, working in underground mining, worker's age and occupational experience. This is the first systematic review of lost-time injuries in the US mining sector. The results support the need for further research on factors that contribute to workplace lost-time injuries as there is limited literature on the topic. Safety analytics should also be applied to uncover new trends and predict the likelihood of future incidents before they occur. New insights will allow employers to prevent injuries and foster a safer workplace environment by implementing successful occupational health and safety programmes. © The Author 2017.

Location-based technologies for supporting elderly pedestrian in "getting lost" events.
Pulido Herrera, Edith
2017-05-01
Localization-based technologies promise to keep older adults with dementia safe and support them and their caregivers during getting lost events. This paper summarizes mainly technological contributions to support the target group in these events. Moreover, important aspects of the getting lost phenomenon such as its concept and ethical issues are also briefly addressed. Papers were selected from scientific databases and gray literature. Since the topic is still in its infancy, other terms were used to find contributions associated with getting lost e.g. wandering. Trends of applying localization systems were identified as personal locators, perimeter systems and assistance systems. The first system barely considered the older adult's opinion, while assistance systems may involve context awareness to improve the support for both the elderly and the caregiver. Since few studies report multidisciplinary work with a special focus on getting lost, there is not a strong evidence of the real efficiency of localization systems or guidelines to design systems for the target group. Further research about getting lost is required to obtain insights for developing customizable systems. Moreover, considering conditions of the older adult might increase the impact of developments that combine localization technologies and artificial intelligence techniques. Implications for Rehabilitation Whilst there is no cure for dementia such as Alzheimer's, it is feasible to take advantage of technological developments to somewhat diminish its negative impact. For instance, location-based systems may provide information to early diagnose the Alzheimer's disease by assessing navigational impairments of older adults. Assessing the latest supportive technologies and methodologies may provide insights to adopt strategies to properly manage getting lost events. More user-centered designs will provide appropriate assistance to older adults. Namely, customizable systems could assist older adults in their daily walks with the aim to increase their self-confidence, independence and autonomy.

This paper examines the feeling of lost control of the body that so many women experience through pregnancy and the postpartum period - why they feel it and how they interpret that feeling - and women's responses to the sense of lost control. For the 63 Canadian women we interviewed, the sense of lost control was related to the degree they felt their bodies changed and the number of physical problems they experienced while pregnant. Many women's references to "luck" as the cause of body changes and problems experienced underscored how little control they felt they had when they were pregnant. At the same time, women felt responsible for the well-being of their babies, and thus experienced guilt about their unruly bodies. Careful attention to diet helped some women, but not others, regain some sense of control; women with past experience of pregnancy who "gave in" to body change were more sanguine. In the postpartum period, body work (especially exercise) functioned to increase women's sense of control, but a variety of motives led them to do this work. Copyright © 2016 Elsevier Ltd.

Cardiovascular diseases are still the leading cause of death in Spain. The DRECE study (Diet and Cardiovascular Disease Risk in Spain), based on a representative cohort of the Spanish general population, analyzed nutritional habits and lifestyle and their association with morbidity and mortality patterns. We estimated the impact, in terms of loss of productivity, of premature mortality attributed to cardiovascular diseases. The loss of productivity attributed to premature mortality was calculated from 1991, based on the potential years of life lost and the potential years of working life lost. During the 20-year follow-up of a cohort of 4779 patients, 225 of these patients died (men, 152). Sixteen percent of the deaths were attributed to cardiovascular disease. The costs due to lost productivity by premature mortality exceeded 29 million euros. Of these, 4 million euros (14% of the total cost) were due to cardiovascular causes. Premature cardiovascular mortality in the DRECE cohort represented a significant social cost due to lost productivity. Copyright © 2014 Elsevier España, S.L.U. All rights reserved.

Transport Control Protocol (TCP) incast congestion happens when a number of senders work in parallel with the same server where the high bandwidth and low latency network problem occurs. For many data center network applications such as a search engine, heavy traffic is present on such a server. Incast congestion degrades the entire performance as packets are lost at a server side due to buffer overflow, and as a result, the response time becomes longer. In this work, we focus on TCP throughput, round-trip time (RTT), receive window and retransmission. Our method is based on the proactive adjust of the TCP receive window before the packet loss occurs. We aim to avoid the wastage of the bandwidth by adjusting its size as per the number of packets. To avoid the packet loss, the ICTCP algorithm has been implemented in the data center network (ToR).
Worker was harassed due to homosexuality, not AIDS.
1999-07-23
An HIV-negative gay man, [name removed], who suffered anti-gay bigotry on the job, lost his suit claiming his employer, General Motors, violated the Americans with Disabilities Act by subjecting him to a hostile work environment. According to [name removed] he was repeatedly harassed and subjected to abuse on the job, including being called "an AIDS case." He went on medical leave twice for psychiatric care, as a result of the harassment. [Name removed] did not allege that supervisors or managers ever perceived him as having AIDS, but he argued that his co-worker's actions substantially limited his ability to perform a major life activity, working. The judge disagreed, pointing out that his employer never regarded him as having AIDS. The judge also found the harassment suffered was sporadic and merely offensive. Evidence also showed that [name removed] was offered a reassignment to another position which he declined.

Sedentariness is associated with weight gain and obesity. A treadmill desk is the combination of a standing desk and a treadmill that allow employees to work while walking at low speed. The hypothesis was that a 1-year intervention with treadmill desks is associated with an increase in employee daily physical activity (summation of all activity per minute) and a decrease in daily sedentary time (zero activity). Employees (n = 36; 25 women, 11 men) with sedentary jobs (87 ± 27 kg, BMI 29 ± 7 kg/m(2) , n = 10 Lean BMI < 25 kg/m(2) , n = 15 Overweight 25 < BMI < 30 kg/m(2) , n = 11 Obese BMI > 30 kg/m(2) ) volunteered to have their traditional desk replaced with a treadmill desk to promote physical activity for 1 year. Daily physical activity (using accelerometers), work performance, body composition, and blood variables were measured at Baseline and 6 and 12 months after the treadmill desk intervention. Subjects who used the treadmill desk increased daily physical activity from baseline 3,353 ± 1,802 activity units (AU)/day to, at 6 months, 4,460 ± 2,376 AU/day (P < 0.001), and at 12 months, 4,205 ± 2,238 AU/day (P < 0.001). Access to the treadmill desks was associated with significant decreases in daily sedentary time (zero activity) from at baseline 1,020 ± 75 min/day to, at 6 months, 929 ± 84 min/day (P < 0.001), and at 12 months, 978 ± 95 min/day (P < 0.001). For the whole group, weight loss averaged 1.4 ± 3.3 kg (P < 0.05). Weight loss for obese subjects was 2.3 ± 3.5 kg (P < 0.03). Access to the treadmill desks was associated with increased daily physical activity compared to traditional chair-based desks; their deployment was not associated with altered performance. For the 36 participants, fat mass did not change significantly, however, those who lost weight (n = 22) lost 3.4 ± 5.4 kg (P < 0.001) of fat mass. Weight loss was greatest in people with obesity. Access to treadmill desks may improve the health of office workers without affecting work performance. Copyright © 2012 The Obesity Society.
Work productivity improvement after acid suppression in patients with uninvestigated dyspepsia.
Bytzer, Peter; Langkilde, Lars K; Christensen, Erik; Meineche-Schmidt, Villy
2012-07-01
Lost productivity accounts for a significant part of the costs caused by gastrointestinal symptoms. We aimed to describe selfreported productivity in patients presenting with dyspepsia. Data were sourced from a randomized, double-blinded study of two weeks of esomeprazole 40 mg or placebo in 805 primary-care patients with uninvestigated dyspepsia. Work productivity was tested using the Work Productivity and Activity Impairment questionnaire. Treatment effect on work productivity loss was tested according to the likelihood of treatment response. A total of 401/805 employed patients were included in the analysis. The average work productivity loss in the past seven days was 10.5 working hours/week. The productivity loss grew with increasing severity of symptoms at baseline. Following two weeks of treatment, the mean improvement in work productivity was significantly higher for both absenteeism (1 hour versus 0.1 hour, p < 0.05) and presenteeism (5.3 hours versus 4.3 hours, p < 0.05) in patients treated with esomeprazole versus placebo. The most substantial improvement was seen in patients who, based on baseline symptoms, were assessed to be likely treatment responders. Dyspepsia symptoms represent a significant economic burden in terms of lost productivity. The RESPONSE algorithm is successful in determining which patients will benefit from acid suppression in terms of enhanced productivity.
[Itinerant physicians, the art of healing and doctors in national history (Mexico City, 1877-1911)].
Agostoni, Claudia
2008-01-01
The uncertainty and mistrust towards the presence and activities of academic medical practitioners in Mexico City during the Porfirio Díaz government (1877-1911) convinced these professionals that is was essential to create, strengthen and transmit a respectable, competent and homogeneous image of the profession. To this purpose they recovered, recreated and adapted the ethical maxims of the occidental medical culture to their professional work, and rescued eminent medical figures of Mexico's convulse nineteenth century from being lost in the oblivion of history. Their goal - as it will be expounded in the following pages - was to respond, oppose and neutralize the criticism and disbelief expressed by the public against their professional performance.
Plastic scintillator enhancement through Quantum Dot

Plastic scintillators such as Polyvinyl Toluene (PVT) are used for radiation detection but due to their poor performance they are not widely implemented. In order to circumnavigate this, dopants are added to enhance scintillation by energy transfer otherwise lost through non-radiative processes. In this work, we exploit the effects of energy transfer through the use of short wavelength emission Cadmium Sulfide Quantum Dots (QD) as the transfer stimulant. Scintillation enhancement was observed as Cadmium Sulfide QD with scintillating dyes are embedded in PVT polymer matrix for beta and gamma radiation. Energy transfer was observed between Quantum Dots, scintillating dye, and the host polymer. Different concentrations of QD and 2,5-diphenyloxazole (PPO) dye are investigated to characterize the energy transfer.

Obesity is a public health problem worldwide. The aim of the present study was to determine the association between the type of working schedule and the sleeping hours per day with obesity and overweight. Cross-sectional study of the National Health Survey in 2012. We conducted an analysis of multinomial logistic regression and estimated the rates of possible risk of obesity and overweight versus the normal weight in relation to the type of working schedule and sleeping hours. Obesity among those who worked at night was 17,50% and those who had irregular works was 17,92%. Overweight among those who performed part-time works was 40,81% and 39,17% in night works. The obesity and overweight among those who slept less than six hours a day were 24,42% and 40,99% respectively. Regression analysis logistic showed OR=1,83 (IC95% 1,15-1,75) in irregular works and OR= 1,83 (IC95% 1,59-2,11) in people who slept less than six hours. Whenever overweight and obesity are present, a positive association between irregular jobs and short patterns of rest has been found, but stadistical significance is lost when estimating the OR adjusting the confounding factors.

Injuries in women associated with a periodized strength training and running program.
Reynolds, K L; Harman, E A; Worsham, R E; Sykes, M B; Frykman, P N; Backus, V L
2001-02-01
Forty-five women participated in a 24-week physical training program designed to improve lifting, load carriage, and running performance. Activities included weightlifting, running, backpacking, lift and carry drills, and sprint running. Physicians documented by passive surveillance all training-related injuries. Thirty-two women successfully completed training program. Twenty-two women (48.9%) suffered least 1 injury during training, but only 2 women had to drop out of the study because of injuries. The rate of injury associated with lost training time was 2.8 injuries per 1,000 training hours of exposure. Total clinic visits and days lost from training were 89 and 69, respectively. Most injuries were the overuse type involving the lower back, knees, and feet. Weightlifting accounted for a majority of the lost training days. A combined strength training and running program resulted in significant performance gains in women. Only 2 out of 45 participants left the training program cause of injuries.
The cost of productivity losses associated with allergic rhinitis.
Crystal-Peters, J; Crown, W H; Goetzel, R Z; Schutt, D C
2000-03-01
To measure the cost of absenteeism and reduced productivity associated with allergic rhinitis. The National Health Interview Survey (NHIS) was used to obtain information on days lost from work and lost productivity due to allergic rhinitis. Wage estimates for occupations obtained from the Bureau of Labor Statistics (BLS) were used to calculate the costs. Productivity losses associated with a diagnosis of allergic rhinitis in the 1995 NHIS were estimated to be $601 million. When additional survey information on the use of sedating over-the-counter (OTC) allergy medications, as well as workers' self-assessments of their reduction in at-work productivity due to allergic rhinitis, were considered, the estimated productivity loss increased dramatically. At-work productivity losses were estimated to range from $2.4 billion to $4.6 billion. Despite the inherent difficulty of measuring productivity losses, our lowest estimate is several times higher than previous estimates of the indirect medical costs associated with allergic rhinitis treatment. The most significant productivity losses resulted not from absenteeism but from reduced at-work productivity associated with the use of sedating OTC antihistamines.
Mineral oil metal working fluids (MWFs)-development of practical criteria for mist sampling.
Simpson, A T; Groves, J A; Unwin, J; Piney, M
2000-05-01
Not all mineral oil metalworking fluids (MWFs) in common use form stable airborne mists which can be sampled quantitatively onto a filter. This much has been known for some time but no simple method of identifying oils too volatile for customary filter sampling has been developed. Past work was reviewed and experiments were done to select simple criteria which would enable such oils to be identified. The sampling efficiency for a range of commercial mineral oil MWF were assessed by drawing clean air through spiked filters at 2 l. min(-1) for periods up to 6 h before analysis. The physical properties of MWF are governed by their composition and kinematic viscosity was found to be the most practical and easily available index of the potential for sample loss from the filter. Oils with viscosities greater that 18 cSt (at 40 degrees C) lost less than 5% of their weight, whereas those with viscosities less than 18 cSt gave losses up to 71%. The losses from the MWF were mostly aliphatic hydrocarbons (C(10)-C(18)), but additives such as alkyl benzenes, esters, phenols and terpene odorants were also lost. The main recommendation to arise from the work is that filter sampling can be performed on mineral oils with viscosities of 18 cSt (at 40 degrees C) or more with little evaporative losses from the filter. However, sampling oils with viscosities less than 18 cSt will produce results which may significantly underestimate the true value. Over a quarter of UK mineral oil MWFs are formulated from mineral oils with viscosities less than 18 cSt (at 40 degrees C). The problem of exposure under-estimation and inappropriate exposure sampling could be widespread. Further work is being done on measurement of mixed phase mineral oil mist exposure.

A personal memoir of Inge Lehmann (1888-1993)

Simon, Ruth
On February 21, the world lost a pioneering woman scientist and I lost a treasured friend.I met Inge Lehmann in the 1950s when she came to Lamont to work on her “Lg” paper. We immediately became friends despite the large difference in our ages. Her quiet dignity, her interest in everything scientific and feminine, her desire to learn all she could about our lives in and out of the observatory astounded me. Inge was shy, almost painfully so. Dr. Ewing arranged for Inge to stay in the guest house where she could do her work and have assistance as needed. One of my most pleasant duties to make her feel at home was to take her on weekly trips to the supermarket. She prepared her own meals in her guest house quarters. I shopped for my own family at the same time, leaving my provisions in the car until it was time to go home after work. Inge kept ice cream and frozen food in her small freezer for me.

Objective: To determine the effectiveness of an office-based multimodal hand hygiene improvement intervention in reducing self-reported communicable infections and work-related absence. Methods: A randomized cluster trial including an electronic training video, hand sanitizer, and educational posters (n = 131, intervention; n = 193, control). Primary outcomes include (1) self-reported acute respiratory infections (ARIs)/influenza-like illness (ILI) and/or gastrointestinal (GI) infections during the prior 30 days; and (2) related lost work days. Incidence rate ratios calculated using generalized linear mixed models with a Poisson distribution, adjusted for confounders and random cluster effects. Results: A 31% relative reduction in self-reported combined ARI-ILI/GI infections (incidence rate ratio: 0.69; 95% confidence interval, 0.49 to 0.98). A 21% nonsignificant relative reduction in lost work days. Conclusions: An office-based multimodal hand hygiene improvement intervention demonstrated a substantive reduction in self-reported combined ARI-ILI/GI infections. PMID:25719534

Objective Many stroke survivors experience poststroke spasticity and the related inability to perform basic activities, which necessitates patient management and treatment, and exerts a considerable burden on the informal caregiver. The current study aims to estimate burden, productivity loss, and indirect costs for caregivers of stroke survivors with spasticity. Methods Internet survey data were collected from 153 caregivers of stroke survivors with spasticity including caregiving time and difficulty (Oberst Caregiver Burden Scale), Work Productivity and Activity Impairment measures, and caregiver and patient characteristics. Fractional logit models examined predictors of work-related restriction, and work losses were monetized (2012 median US wages). Results Mean Oberst Caregiver Burden Scale time and difficulty scores were 46.1 and 32.4, respectively. Employed caregivers (n=71) had overall work restriction (32%), absenteeism (9%), and presenteeism (27%). Caregiver characteristics, lack of nursing home coverage, and stroke survivors’ disability predicted all work restriction outcomes. The mean total lost-productivity cost per employed caregiver was US$835 per month (>$10,000 per year; 72% attributable to presenteeism). Conclusion These findings demonstrate the substantial burden of caring for stroke survivors with spasticity illustrating the societal and economic impact of stroke that extends beyond the stroke survivor.

2002-10-01
We reviewed treatment outcomes in a series of aviation pilots treated in the era of modern surgical techniques and provide recommendations regarding treatment in this unique group. We retrospectively analyzed the records of all aviation pilots surgically treated for urinary calculi at our 4 tertiary stone centers from January 1988 to June 2000. Preoperative data and postoperative results were evaluated. Primary outcome measures included stone-free status after initial therapy, time lost from work and overall stone-free rates. Secondary outcome measures included the need for secondary procedures and complications. Of the 36 patients 17 had renal and 19 had ureteral stones. In 4 patients the stones passed spontaneously, while 17 were initially treated with extracorporeal shock wave lithotripsy (ESWL) (Dornier Medical Systems, Marietta, Georgia), 9 were initially treated with ureteroscopy and 6 were treated with percutaneous nephrolithotripsy. There was 1 complication. The stone-free rate for ESWL, percutaneous nephrolithotripsy and ureteroscopy after initial therapy was 35%, 100% and 100%, respectively. All patients were rendered stone-free after secondary therapy. Mean time lost from work for ESWL, percutaneous nephrolithotripsy and ureteroscopy was 4.7, 2.6 and 1.6 weeks, respectively. Aviation pilots with surgical urolithiasis are best treated with an initial endoscopic procedure. Stone-free rates can be maximized, while time lost from work can be minimized when an endoscopic approach is used initially. All pilots with urolithiasis should undergo mandatory metabolic evaluations to institute medical therapy when indicated.

In a packet erasure network environment, video streaming benefits from error control in two ways to achieve graceful degradation. The first approach is application-level (or the link-level) forward error-correction (FEC) to provide erasure protection. The second error control approach is error concealment at the decoder end to compensate lost packets. A large amount of research work has been done in the above two areas. More recently, network coding (NC) techniques have been proposed for efficient data multicast over networks. It was shown in our previous work that multicast video streaming benefits from NC for its throughput improvement. An algebraic model is given to analyze the performance in this work. By exploiting the linear combination of video packets along nodes in a network and the SVC video format, the system achieves path diversity automatically and enables efficient video delivery to heterogeneous receivers in packet erasure channels. The application of network coding can protect video packets against the erasure network environment. However, the rank defficiency problem of random linear network coding makes the error concealment inefficiently. It is shown by computer simulation that the proposed NC video multicast scheme enables heterogenous receiving according to their capacity constraints. But it needs special designing to improve the video transmission performance when applying network coding.

To analyze the association between occupational factors (number of contracts and occupational category) and potential years of working life lost (PYWLL) due to non-work related permanent disability (PD). The study design was a retrospective cohort of 11,812 workers affiliated with the Social Security System in Spain that began a non-work related PD between 2004 and 2009. The PYWLL was defined as the time in years between the age at which a worker initiates a PD and age 65 or the age of reinstatement to a job. The PYWLL was analyzed by calculating the quartiles and using an approach based on a median regression. The difference in medians of PYWLL between men and women was 2.49 years (95% CI: 2.01-2.97); between skilled non-manual and unskilled manual workers was 1.88 years (95% CI: 1.08-2.69); between workers with three or more contracts and workers with a single contract in the period was 3.78 years (95% CI: 3.28-4.29). Women, non-skilled workers and employees that have had more contracts within the period of study are those with greatest loss of PYWLL. This suggests that individuals with poorer working and employment conditions could have more PYWLL.

Compression ignition engines transform approximately 40% of the fuel energy into power available at the crankshaft, while the rest part of the fuel energy is lost as coolant, exhaust gases and other waste heat. An organic Rankine cycle (ORC) can be used to recover this waste heat. In this paper, the characteristics of a system combining a compression ignition engine with an ORC which recover the waste heat from the exhaust gases are analyzed. The performance map of the diesel engine is measured on an engine test bench and the heat quantities wasted by the exhaust gases are calculated over the engine's entire operating region. Based on this data, the working parameters of ORC are defined, and the performance of a combined engine-ORC system is evaluated across this entire region. The results show that the net power of ORC is 6.304kW at rated power point and a maximum of 10% reduction in brake specific fuel consumption can be achieved.

Nowadays, ca. 176,640 tons/year of silicon (Si) (>4N) is manufactured for Si wafers used for semiconductor industry. The production of the highly pure Si wafers inevitably includes very high-temperature steps at 1400-2000 °C, which is energy-consuming and environmentally unfriendly. Inefficiently, ca. 45-55% of such costly Si is lost simply as sawdust in the cutting process. In this work, we develop a cost-effective way to recycle Si sawdust as a high-performance anode material for lithium-ion batteries. By a beads-milling process, nanoflakes with extremely small thickness (15-17 nm) and large diameter (0.2-1 μm) are obtained. The nanoflake framework is transformed into a high-performance porous structure, named wrinkled structure, through a self-organization induced by lithiation/delithiation cycling. Under capacity restriction up to 1200 mAh g-1, the best sample can retain the constant capacity over 800 cycles with a reasonably high coulombic efficiency (98-99.8%).

The apparent kinetic of the ultrasound assisted liquid-phase dehydrogenation of isopropanol over Raney nickel catalyst was determined in the temperature range of 346-353 K. Comparison of the effects of ultrasound and mechanical agitation on the isopropanol dehydrogenation was investigated. The ultrasound assisted dehydrogenation rate was significantly improved when relatively high power density was used. Moreover, the Isopropanol-Acetone-Hydrogen chemical heat pump (IAH-CHP) with ultrasound irradiation, in which the endothermic reaction is exposure to ultrasound, was proposed. A mathematical model was established to evaluate its energy performance in term of the coefficient of performance (COP) and the exergy efficiency, into which the apparent kinetic obtained in this work was incorporated. The operating performances between IAH-CHP with ultrasound and mechanical agitation were compared. The results indicated that the superiority of the IAH-CHP system with ultrasound was present even if more than 50% of the power of the ultrasound equipment was lost. Copyright © 2014 Elsevier B.V.

Financial concerns represent a major stressor for families of children with cancer but remain poorly understood among those with terminally ill children. We describe the financial hardship, work disruptions, income loss, and coping strategies of families who lost children to cancer. Retrospective cross-sectional survey of 141 American and 89 Australian bereaved parents whose children died between 1990 and 1999 and 1996 to 2004, respectively, at three tertiary-care pediatric hospitals (two American, one Australian). Response rate: 63%. Thirty-four (24%) of 141 families from US centers and 34 (39%) of 88 families from the Australian center reported a great deal of financial hardship resulting from their children's illness. Work disruptions were substantial (84% in the United States, 88% in Australia). Australian families were more likely to report quitting a job (49% in Australia v 35% in the United States; P = .037). Sixty percent of families lost more than 10% of their annual income as a result of work disruptions. Australians were more likely to lose more than 40% of their income (34% in Australia v 19% in the United States; P = .035). Poor families experienced the greatest income loss. After accounting for income loss, 16% of American and 22% of Australian families dropped below the poverty line. Financial hardship was associated with poverty and income loss in all centers. Fundraising was the most common financial coping strategy (52% in the United States v 33% in Australia), followed by reduced spending. In these US and Australian centers, significant household-level financial effects of a child's death as a result of cancer were observed, especially for poor families. Interventions aimed at reducing the effects of income loss may ease financial distress.

Abstract Chronic respiratory diseases such as asthma, allergic rhinitis (AR), chronic obstructive pulmonary disease (COPD), and rhinosinusitis are becoming increasingly prevalent in the Asia-Pacific region. The Asia-Pacific Burden of Respiratory Diseases (APBORD) study was a cross-sectional, observational study which examined the disease and economic burden of AR, asthma, COPD, and rhinosinusitis across Asia-Pacific using 1 standard protocol. Here we report symptoms, healthcare resource use (HCRU), work impairment, and associated cost in Taiwan. Consecutive participants aged ≥ 18 years presenting to a physician with symptoms meeting the diagnostic criteria for a primary diagnosis of asthma, AR, COPD, or rhinosinusitis were enrolled. Participants and their treating physician completed surveys detailing respiratory symptoms, HCRU, work productivity, and activity impairment. Costs including direct medical costs and indirect costs associated with lost work productivity were calculated. The study enrolled 1001 patients. AR was the most frequent primary diagnosis (31.2%). A quarter of patients presented with a combination of respiratory diseases, with AR and asthma being the most frequent combination (14.1%). Cough or coughing up phlegm was the primary reason for the medical visit for patients with asthma and COPD, whereas nasal symptoms (watery runny nose, blocked nose, and congestion) were the primary reasons for AR and rhinosinusitis. Specialists were the most frequently used healthcare resource by patients with AR (26.1%), asthma (26.4%), COPD (26.6%), and rhinosinusitis (47.3%). The mean annual cost per patient with a respiratory disease was US$4511 (SD 5395). The cost was almost double for employed patients (US$8047, SD 6175), with the majority attributable to lost productivity. Respiratory diseases have a significant impact on disease burden in Taiwan. Treatment strategies that prevent lost work productivity could greatly reduce the economic burden of these diseases. PMID:27399064

Cited as the largest single cause of lost work time and on-the-job fatalities for U.S. workers, motor vehicle crashes cause major nonrecoverable losses for U.S. businesses. Workplace programs to encourage employees to wear safety belts can thus help employers reduce traffic accident-related losses of work time and can substantially reduce the…

Despite the growing worldwide burden of dengue fever, the global economic impact of dengue illness is poorly documented. Using a common protocol, we present the first multicountry estimates of the direct and indirect costs of dengue cases in eight American and Asian countries. We conducted prospective studies of the cost of dengue in five countries in the Americas (Brazil, El Salvador, Guatemala, Panama, and Venezuela) and three countries in Asia (Cambodia, Malaysia, and Thailand). All studies followed the same core protocol with interviews and medical record reviews. The study populations were patients treated in ambulatory and hospital settings with a clinical diagnosis of dengue. Most studies were performed in 2005. Costs are in 2005 international dollars (I$). We studied 1,695 patients (48% pediatric and 52% adult); none died. The average illness lasted 11.9 days for ambulatory patients and 11.0 days for hospitalized patients. Among hospitalized patients, students lost 5.6 days of school, whereas those working lost 9.9 work days per average dengue episode. Overall mean costs were I$514 and I$1,394 for an ambulatory and hospitalized case, respectively. With an annual average of 574,000 cases reported, the aggregate annual economic cost of dengue for the eight study countries is at least I$587 million. Preliminary adjustment for under-reporting could raise this total to $1.8 billion, and incorporating costs of dengue surveillance and vector control would raise the amount further. Dengue imposes substantial costs on both the health sector and the overall economy.

We report a case of a lost metal platelet from a radiofrequency ablation probe (VAPR VUE Radiofrequency System, Cool Pulse 90, DePuy, Synthes, Switzerland) in the shoulder joint during elective arthroscopic cuff repair. To the best of our knowledge, this kind of an incident during elective arthroscopy has not been described in the literature so far. In addition, we present an algorithm on how to deal with such an incident. A 69-year-old woman underwent an arthroscopic subacromial decompression and rotator cuff repair for a torn supraspinatus tendon. While performing the subacromial decompression and after swapping the portals from lateral to posterior, the metal platelet of the electrocautery device got detached from the instrument and lost in the operation field. Several attempts to visualize the lost platelet with the camera failed. Finally, intraoperative fluoroscopic imaging was used to detect the platelet. To confirm the definitive whereabouts of the platelet, two spinal needles were positioned perpendicular to another under x-ray control, both pointing at the missing platelet. After determining the exact location, the platelet could finally be visualized with the camera and removed. Due to this incident, the operation time was extended extensively, and the patient as well as the theatre team was exposed to an unnecessary amount of radiation. This report indicates that an extraordinary incident such as the detachment of a component of the arthroscopic equipment during surgery is possible and should be kept in mind by the surgeon. Therefore, we believe that it is essential to perform a test of integrity at least at the end of every operation. In addition, we are presenting an algorithm on how to deal with the situation of a lost foreign body during arthroscopy, which can be applied to any joint.

Purpose A total of 243 Danish female sewing machine operators lost their jobs in 1996 because of outsourcing. The aim was to investigate the employment status during follow-up from 1996 to 2008, and to estimate to what extent former neck-shoulder pain had an impact on later work participation. Methods Assessment of neck-shoulder pain was based on questionnaires completed in 1994. The Danish Register-Based Evaluation of Marginalization (DREAM) register was used to describe employment status during the follow-up period. Register data were explored by sequence analyses and graphics, and the association between neck-shoulder pain and work participation was analyzed by logistic regression analysis. Results In all, 987 working years were lost during follow-up, and a sequence index plot revealed interrupted and heterogeneous courses of incomes. The odds ratio between neck and shoulder pain and a work participation score less than 75% was 1.49 (95% CI 0.84-2.67). Conclusions After outsourcing of the textile industry, the former sewing machine operators had decreased work participation and frequent transitions between different income types. Previous neck-shoulder pain tended to be associated with poor work participation. The results suggest that increased attention should be to given to dismissed workers from other industries that become outsourced, especially unskilled workers with similar work-related health limitations. Additionally, we concluded that time-to-event measures in research involving employment status are insufficient because of the many transitions that take place in working life.

Individuals who work in the construction industry are at high risk of occupational injury. Robust surveillance systems are needed to monitor the experiences of these workers over time. We updated important surveillance data for a unique occupational cohort of union construction workers to provide information on long-term trends in their reported work-related injuries and conditions. Combining administrative data sources, we identified a dynamic cohort of union carpenters who worked in Washington State from 1989 through 2008, their hours worked by month, and their workers' compensation claims. Incidence rates of reported work-related injuries and illnesses were examined. Poisson regression was used to assess risk by categories of age, gender, time in the union, and calendar time contrasting medical only and paid lost time claims. Over the 20-year study period, 24,830 carpenters worked 192.4 million work hours. Work-related injuries resulting in medical care or paid lost time (PLT) from work occurred at a rate of 24.3 per 200,000 hr worked (95% CI: 23.5-25.0). Medical only claims declined 62% and PLT claims declined 77%; more substantive declines were seen for injuries resulting from being struck and falls to a lower level than from overexertion with lifting. Differences in risk based on union tenure and age diminished over time as well. Significant declines in rates of reported work-related injuries and illnesses were observed over the 20-year period among these union carpenters. Greater declines were observed among workers with less union tenure and for claims resulting in PLT. Copyright © 2012 Wiley Periodicals, Inc.
Beyond money and survival: the meaning of paid work among older women.
Altschuler, Joanne
2004-01-01
This article explores the meaning and experiences of paid work for older women. Taped, in-person interviews were conducted with 53 ethnically and economically diverse women, 55 to 84 years old. The interview guide contained open-ended questions regarding the meaning of work, reasons for working, and the centrality of work to personal identity. Participants discussed the following topics: independence from men; lost dreams and regrets related to paid work and educational opportunities; being responded to as mother by co-workers and supervisors; and working above and beyond the call of duty.
Irreversible thermodynamic analysis and application for molecular heat engines

Lucia, Umberto; Açıkkalp, Emin
2017-09-01
Is there a link between the macroscopic approach to irreversibility and microscopic behaviour of the systems? Consumption of free energy keeps the system away from a stable equilibrium. Entropy generation results from the redistribution of energy, momentum, mass and charge. This concept represents the essence of the thermodynamic approach to irreversibility. Irreversibility is the result of the interaction between systems and their environment. The aim of this paper is to determine lost works in a molecular engine and compare results with macro (classical) heat engines. Firstly, irreversible thermodynamics are reviewed for macro and molecular cycles. Secondly, irreversible thermodynamics approaches are applied for a quantum heat engine with -1/2 spin system. Finally, lost works are determined for considered system and results show that macro and molecular heat engines obey same limitations. Moreover, a quantum thermodynamic approach is suggested in order to explain the results previously obtained from an atomic viewpoint.

Objective Our objectives were to describe a sample of truck drivers, identify clusters of drivers with similar patterns in behaviors affecting energy balance (sleep, diet, and exercise), and test for cluster differences in health and psychosocial factors. Methods Participants’ (n=452, BMI M=37.2, 86.4% male) self-reported behaviors were dichotomized prior to hierarchical cluster analysis, which identified groups with similar behavior co-variation. Cluster differences were tested with generalized estimating equations. Results Five behavioral clusters were identified that differed significantly in age, smoking status, diabetes prevalence, lost work days, stress, and social support, but not in BMI. Cluster 2, characterized by the best sleep quality, had significantly lower lost workdays and stress than other clusters. Conclusions Weight management interventions for drivers should explicitly address sleep, and may be maximally effective after establishing socially supportive work environments that reduce stress exposures.

Identification - obstacle to individuation, or: on how to become 'me'.
Cavalli, Alessandra
2017-04-01
This paper will explore the use of identification with aspects of a lost object as a defensive strategy to cope with traumatic loss, and will show how in the depth of the analytic work this identification can be accessed and made conscious. Descriptions of work with a three-year-old boy illustrate how the sudden loss of his mother's breasts had made weaning un-accessible to him, and how, in the absence of a good experience of separation, the process of mourning had not been able to take place. Instead, identification with aspects of the lost breast was used as a defence against pain, and this state of affairs was proving a hindrance to individuation. In the discussion of the case material, the use of identification as a defence will be highlighted, and a differentiation made between abandonment and separation as this illuminates the link between mourning and individuation. © 2017, The Society of Analytical Psychology.

We investigated patterns and costs of lost productivity due to colorectal cancer in Ireland and examined how rising pension ages affect these costs. Data from a postal survey of colorectal cancer survivors (6 to 30 months after diagnosis; n = 159), taken from March 2010 to January 2011, were combined with population-level survival estimates and national wage data to calculate temporary and permanent disability, and premature mortality, costs using the human capital approach. Almost 40% of respondents left the workforce permanently after diagnosis and 90% took temporary time off work. Total costs of lost productivity per person were 205,847 in 2008 assuming retirement at the age of 65. When the retirement age was raised to 70, productivity costs increased by almost a half. Our study demonstrated the considerable productivity costs associated with colorectal cancer and highlighted the effect of rising retirement ages on costs.

The objectives of the study were to describe a sample of truck drivers, identify clusters of drivers with similar patterns in behaviors affecting energy balance (sleep, diet, and exercise), and test for cluster differences in health safety, and psychosocial factors. Participants' (n = 452, body mass index M = 37.2, 86.4% male) self-reported behaviors were dichotomized prior to hierarchical cluster analysis, which identified groups with similar behavior covariation. Cluster differences were tested with generalized estimating equations. Five behavioral clusters were identified that differed significantly in age, smoking status, diabetes prevalence, lost work days, stress, and social support, but not in body mass index. Cluster 2, characterized by the best sleep quality, had significantly lower lost workdays and stress than other clusters. Weight management interventions for drivers should explicitly address sleep, and may be maximally effective after establishing socially supportive work environments that reduce stress exposures.

Objective To assess changes in work productivity in patients who have achieved response using etanercept (ETN) 50 mg+methotrexate (MTX) (phase I) are randomised to ETN 25 mg+MTX versus MTX versus placebo (phase II) and then withdrawn from treatment (phase III). Methods Patients included in the analysis were in employment entering phase II of the PRIZE trial and had one or more follow-ups. Phase II was a 39-week, randomised and double-blind comparison of the 3 dose-reduction treatments. Phase III was a 26-week observational study where treatment was withdrawn. The Valuation of Lost Productivity was completed approximately every 13 weeks to estimate productivity impacts from a societal perspective. Results A total of 120 participants were included in our analyses. During phase II, ETN25+MTX or MTX improved paid work productivity by over 100 hours compared with placebo, amounting to a gain of €1752 or €1503, respectively. ETN25+MTX compared with placebo gains €1862 in total paid/unpaid productivity. At week 52, the 3-month paid work productivity loss was 21.8, 12.8 and 14.0 hours, respectively. The productivity loss increased at week 64 from week 52, dropped at week 76 for all treatment groups and then continued rising after week 76 for the placebo group (71.9 hours at week 91) but not for the other 2 groups (21.9 hours for ETX25+MTX and 27.6 hours for MTX). Conclusions The work productivity gain in phase I as a result of ETN50+MTX was marginally lost in the dose-reduction treatment groups, ETN25+MTX and MTX, but substantially lost in the placebo group during phase II.

Background As many respiratory viruses are responsible for influenza like symptoms, accurate measures of the disease burden are not available and estimates are generally based on statistical methods. The objective of this study was to estimate absenteeism rates and hours lost due to seasonal influenza and compare these estimates with estimates of absenteeism attributable to the two H1N1 pandemic waves that occurred in 2009. Methods Key absenteeism variables were extracted from Statistics Canada's monthly labour force survey (LFS). Absenteeism and the proportion of hours lost due to own illness or disability were modelled as a function of trend, seasonality and proxy variables for influenza activity from 1998 to 2009. Results Hours lost due to the H1N1/09 pandemic strain were elevated compared to seasonal influenza, accounting for a loss of 0.2% of potential hours worked annually. In comparison, an estimated 0.08% of hours worked annually were lost due to seasonal influenza illnesses. Absenteeism rates due to influenza were estimated at 12% per year for seasonal influenza over the 1997/98 to 2008/09 seasons, and 13% for the two H1N1/09 pandemic waves. Employees who took time off due to a seasonal influenza infection took an average of 14 hours off. For the pandemic strain, the average absence was 25 hours. Conclusions This study confirms that absenteeism due to seasonal influenza has typically ranged from 5% to 20%, with higher rates associated with multiple circulating strains. Absenteeism rates for the 2009 pandemic were similar to those occurring for seasonal influenza. Employees took more time off due to the pandemic strain than was typical for seasonal influenza.

To explore the monetary value of rheumatoid arthritis related loss of productivity in patients with early active disease. In a prospective cohort substudy of the FIN-RACo Trial, 162 patients with recent onset rheumatoid arthritis, aged 18 to 65 years and available to the workforce, were followed up for five years. Loss of work productivity in euros 2002 was estimated by data on absence for sickness and on income (human capital approach) from official databases. Treatment responses were evaluated by area under the curve (AUC) of the ACR-N measure and by increase in number of erosions in radiographs of hands and feet. The health assessment questionnaire (HAQ) at six months was linked to the International Classification of Functioning, Disability and Health (ICF). In all, 120 (75%) patients, women more often (82%) than men (61%) (p=0.002), lost work days. The mean lost productivity per patient-year was euro7217 (95% confidence interval (CI), 5561 to 9148): for women, euro6477 (4858 to 8536) and for men, euro8443 (5389 to 12,898). There was an inverse correlation with improvement: euro1101 (323 to 2156) and euro14 952 (10,662 to 19,852) for the highest and lowest quartiles of AUC of ARC-N, respectively. Lost productivity was associated with increase in the number of erosions and with disability in "changing and maintaining body position" subcategory of the ICF. Despite remission targeted treatment with disease modifying antirheumatic drugs, early rheumatoid arthritis results in substantial loss of productivity. A good improvement in the disease reduces the loss markedly.

To explore methodological refinements in measuring health-related lost productivity and to assess the business implications of a full-cost approach to managing health. Health-related lost productivity was measured among 10 employers with a total of 51,648 employee respondents using the Health and Work Performance Questionnaire combined with 1,134,281 medical and pharmacy claims. Regression analyses were used to estimate the associations of health conditions with absenteeism and presenteeism using a range of models. Health-related productivity costs are significantly greater than medical and pharmacy costs alone (on average 2.3 to 1). Chronic conditions such as depression/anxiety, obesity, arthritis, and back/neck pain are especially important causes of productivity loss. Comorbidities have significant non-additive effects on both absenteeism and presenteeism. Executives/Managers experience as much or more monetized productivity loss from depression and back pain as Laborers/Operators. Testimonials are reported from participating companies on how the study helped shape their corporate health strategies. A strong link exists between health and productivity. Integrating productivity data with health data can help employers develop effective workplace health human capital investment strategies. More research is needed to understand the impacts of comorbidity and to evaluate the cost effectiveness of health and productivity interventions from an employer perspective.
Novel manure management technologies in no-till and forage introduction to the special series.
Maguire, Rory O; Kleinman, Peter J A; Beegle, Douglas B
2011-01-01
Surface application of manures leaves nitrogen (N) and phosphorus (P) susceptible to being lost in runoff, and N can also be lost to the atmosphere through ammonia (IH3) volatilization. Tillage immediately after surface application of manure moves manure nutrients under the soil surface, where they are less vulnerable to runoff and volatilization loss. Tillage, however, destroys soil structure, can lead to soil erosion, and is incompatible with forage and no-till systems. A variety of technologies are now available to place manure nutrients under the soil surface, but these are not widely used as surface broadcasting is cheap and long established as the standard method for land application of manure. This collection of papers includes agronomic, environmental, and economic assessments of subsurface manure application technologies, many of which clearly show benefits when comparedwith surface broadcasting. However, there remain significant gaps in our current knowledge, some related to the site-specific nature of technological performance, others related to the nascent and incomplete nature of the assessment process. Thus, while we know that we can improve land application of manure and the sustainability of farming systems with alternatives to surface broadcasting, many questions remain concerning which technologies work best for particular soils, manure types, and farming and cropping systems.

A study was initiated to investigate the practicality of increasing rotor critical speeds by changes in manufacturing method. The technique would be to build a pump with an all laser welded shaft and case; such unit to be opened by laser cutting and rebuilt by rewelding the same surface. Use of a split casing, common in industry, would permit assembly of the rotor outside the case. A team was formed to perform the study; however, the work of the team was severely restricted by conflict with higher priority tasks. No manpower was available to evaluate alternate configurations. Thus, much of the synergetic effects of cohesive design modification was lost. Although very limited results were achieved, nothing was found to indicate that the method is not worth further investigation.

Process automation in pitch-coke plants has increased productivity, prolonged oven life, reduced manning requirements and, above all, improved working conditions and reduced air pollution. The pollution level in the working places has been reduced 5-fold and industrial diseases have been reduced by 17.5% of cases and 11.9% of days lost. Reductions in temporary absenteeism through illness are a major aid towards higher labor productivity.

Examining the available databases and existing tourism organizations can conclude that appear studies on accidents and their relationship with other variables. But in our case we want to assess this relationship in the performance of the hotel in relation to lower the accident rate. The Industrial Safety studies analyzing this accident causes (why they happen), their sources (committed activities), their agents (participants work means), its type (how the events occur or develop), all in order to develop prevention. In our case, as accidents happen because people commit wrongful acts or because the equipment, tools, machinery or workplaces are not in proper conditions, the preventive point of view we analyze through the incidence of workplace accidents hotel subsector. The crash occurs because there is a risk, so that adequate control of it would avoid despite individual factors. Absenteeism or absence from work was taken into account first by Dubois in 1977, as he realized the time lost in the nineteenth century due to the long working hours, which included the holidays. Motivation and job satisfaction were the elements that have been most important in the phenomenon of social psychology.

Whether single crowns produced by computer-aided design and computer-aided manufacturing (CAD-CAM) have an internal fit comparable to crowns made by lost-wax metal casting technique is unknown. The purpose of this in vitro study was to compare the internal fit of single crowns produced with the lost-wax and metal casting technique with that of single crowns produced with the CAD-CAM technique. The internal fit of 5 groups of single crowns produced with the CAD-CAM technique was compared with that of single crowns produced in cobalt-chromium with the conventional lost-wax and metal casting technique. Comparison was performed using the triple-scan protocol; scans of the master model, the crown on the master model, and the intaglio of the crown were superimposed and analyzed with computer software. The 5 groups were milled presintered zirconia, milled hot isostatic pressed zirconia, milled lithium disilicate, milled cobalt-chromium, and laser-sintered cobalt-chromium. The cement space in both the mesiodistal and buccopalatal directions was statistically smaller (P<.05) for crowns made by the conventional lost-wax and metal casting technique compared with that of crowns produced by the CAD-CAM technique. Single crowns made using the conventional lost-wax and metal casting technique have better internal fit than crowns produced using the CAD-CAM technique.

Reductions in heart rate occur frequently in children during critical care intubation and are currently considered the gold standard for haemodynamic instability. Our objective was to estimate loss of heart beats during intubation and compare this to reduction in heart rate alone whilst testing the impact of atropine pre-medication. Data were extracted from a prospective 2-year cohort study of intubation ECGs from critically ill children in PICU/Paediatric Transport. A three step algorithm was established to exclude variation in pre-intubation heart rate (using a 95%CI limit derived from pre-intubation heart rate variation of the children included), measure the heart rate over time and finally the estimate the numbers of lost beats. 333 intubations in children were eligible for inclusion of which 245 were available for analysis (74%). Intubations where the fall in heart rate was less than 50 bpm were accompanied almost exclusively by less than 25 lost beats (n = 175, median 0 [0-1]). When there was a reduction of >50 bpm there was a poor correlation with numbers of lost beats (n = 70, median 42 [15-83]). During intubation the median number of lost beats was 8 [1]-[32] when atropine was not used compared to 0 [0-0] when atropine was used (p<0.001). A reduction in heart rate during intubation of <50 bpm reliably predicted a minimal loss of beats. When the reduction in heart rate was >50 bpm the heart rate was poorly predictive of lost beats. A study looking at the relationship between lost beats and cardiac output needs to be performed. Atropine reduces both fall in heart rate and loss of beats. Similar area-under-the-curve methodology may be useful for estimating risk when biological parameters deviate outside normal range.

PET/CT may be more helpful than CT alone for radiation therapy planning, but the added risk due to higher doses of ionizing radiation is unknown. To estimate the risk of cancer induction and mortality attributable to the [F-18]2-fluoro-2-deoxyglucose (FDG) PET and CT scans used for radiation therapy planning in children with cancer, and compare to the risks attributable to the cancer treatment. Organ doses and effective doses were estimated for 40 children (2-18 years old) who had been scanned using PET/CT as part of radiation therapy planning. The risk of inducing secondary cancer was estimated using the models in BEIR VII. The prognosis of an induced cancer was taken into account and the reduction in life expectancy, in terms of life years lost, was estimated for the diagnostics and compared to the life years lost attributable to the therapy. Multivariate linear regression was performed to find predictors for a high contribution to life years lost from the radiation therapy planning diagnostics. The mean contribution from PET to the effective dose from one PET/CT scan was 24% (range: 7-64%). The average proportion of life years lost attributable to the nuclear medicine dose component from one PET/CT scan was 15% (range: 3-41%). The ratio of life years lost from the radiation therapy planning PET/CT scans and that of the cancer treatment was on average 0.02 (range: 0.01-0.09). Female gender was associated with increased life years lost from the scans (P < 0.001). Using FDG-PET/CT instead of CT only when defining the target volumes for radiation therapy of children with cancer does not notably increase the number of life years lost attributable to diagnostic examinations.
Determining the level and cost of sickness presenteeism among hospital staff in Turkey.
Aysun, Kandemir; Bayram, Şahin
2017-12-01
This study aimed to determine the associations between sickness presenteeism and socio-demographic factors, perceived health status and health complaints among hospital staff and to calculate the cost burdens and productivity losses attributed to presenteeism. A cross-sectional study was conducted using 951 hospital staff, including physicians, nurses, midwives, other health personnel and administrative staff working in two hospitals located in Kırıkkale province in Turkey. The health and work performance questionnaire developed by Kessler et al. was revised to measure sickness presenteeism. After performing Student's t test and a one-way analysis of variance, presenteeism was mostly observed in women, nurse-midwives, young employees, university health staff and health workers with low health status. Average productivity loss and cost of lost productivity per staff member were calculated as 19.92 h/TRY 315.57 for 2 weeks and 478.08 h/TRY 7573.68 for 1 year. The problem of sickness presenteeism is mostly observed in women and nurses. It causes both financial burdens and productivity losses for hospitals. These survey results are thus expected to provide critically important information on presenteeism for decision-makers and healthcare managers.

Ballistic protective helmets can impair heat dissipation. A cooling device in the helmet (cooling pad, CP) could help prevent heat problems in military personnel and potentially enhance comfort. This study examined the effects of CP on rectal and skin temperatures, heart rate, percent change in plasma volume, urine specific gravity, rating of perceived exertion, and other subjective measures while performing light work in a hot environment. It was hypothesized that the CP would act as an insulator to the head, which would not positively affect any physiological variable but could positively affect wearer subjective comfort or temperature. Participants performed a work protocol for approximately 2 hr. A ballistic vest, slacks, short-sleeved button-up shirt, and a ballistic helmet (one trial with CP and one trial without) were worn. Repeated measures analysis of variance (ANOVA) showed no differences (p > 0.05) between wearing and not wearing the CP for any physiological parameter. However, participants perceived the CP as cooler (p = 0.002). Other trends in perceptual data such as thermal strain and helmet comfort indicated the CP felt cooler. However, based on forehead temperature and participant comments, the CP lost its cooling ability relatively quickly (within approximately 30 min).

Exploring the formation of an employee injury team.
Klingel, P
1997-01-01
In May 1994, it was noted that lost work days due to employee injuries were out of control at MedCenter Hospital in Marion, OH. An employee injury team was commissioned by the continuous quality improvement steering committee to investigate and make recommendations to reduce lost workdays. An analysis of the situation required a data search that revealed several patterns and trends. This information was then examined and a decision was made to institute a "Back Care: Train the Trainer" program to reduce the major cause of employee injuries--back sprains and strains. The concept of teamwork is defined and the developmental process of a team is explored.

Mobile surveillance systems are used to find lost radioactive sources and possible nuclear threats in urban areas. The REWARD collaboration [1] aims to develop such a complete radiation monitoring system that can be installed in mobile or stationary setups across a wide area. The scenarios include nuclear terrorism threats, lost radioactive sources, radioactive contamination and nuclear accidents. This paper will show the performance capabilities of the REWARD system in different scnarios. The results include both Monte Carlo simulations as well as neutron and gamma-ray detection performances in terms of efficiency and nuclide identification. The outcomes of several radiation mapping survey with the entire REWARD system will also be presented.

Addressing attention-deficit/hyperactivity disorder in the workplace.
Sarkis, Elias
2014-09-01
Although generally considered a childhood disorder, attention-deficit/hyperactivity disorder (ADHD) can persist into adulthood and impede achievement in the workplace. Core ADHD symptoms of inattention, hyperactivity, and impulsivity can be associated with poor organization, time management, and interpersonal relationships. Employment levels, earning power, and productivity are reduced among individuals with ADHD compared with those without ADHD. Furthermore, the costs of employing individuals with ADHD are higher because of work absences and lost productivity. The primary care provider plays an integral role in managing ADHD symptoms and providing the necessary resources that will help individuals with ADHD succeed in the workplace. Pharmacotherapy can reduce ADHD symptoms and improve functioning; however, it is also important to consider how positive traits associated with ADHD, such as creative thinking, can be used in the workplace. Workplace accommodations and behavioral therapies, such as coaching, can also enhance time management and organizational skills. This review describes how ADHD symptoms affect workplace behaviors, the effect of ADHD on employment and workplace performance, and the management of ADHD in working adults.

Twin studies have lacked statistical power to apply advanced genetic modelling techniques to the search for cognitive endophenotypes for bipolar disorder. To quantify the shared genetic variability between bipolar disorder and cognitive measures. Structural equation modelling was performed on cognitive data collected from 331 twins/siblings of varying genetic relatedness, disease status and concordance for bipolar disorder. Using a parsimonious AE model, verbal episodic and spatial working memory showed statistically significant genetic correlations with bipolar disorder (rg = |0.23|-|0.27|), which lost statistical significance after covarying for affective symptoms. Using an ACE model, IQ and visual-spatial learning showed statistically significant genetic correlations with bipolar disorder (rg = |0.51|-|1.00|), which remained significant after covarying for affective symptoms. Verbal episodic and spatial working memory capture a modest fraction of the bipolar diathesis. IQ and visual-spatial learning may tap into genetic substrates of non-affective symptomatology in bipolar disorder. © The Royal College of Psychiatrists 2016.

Despite efforts to increase patient safety, hundreds of thousands of lives are lost each year to preventable health care errors. The Institute of Medicine and other organizations have recommended that facilitating effective interprofessional health care team work can help address this problem. While the concept of interprofessional health care teams is known, understanding and organizing effective team performance have proven to be elusive goals. Although considerable research has been conducted in the civilian sector, scholars have yet to extend research to the military context. Indeed, delivering the highest caliber of health care to our service men and women is vitally important. This commentary describes a new initiative as the Uniformed Services University of the Health Sciences aimed at researching the characteristics of successful military interprofessional teams and why those characteristics are important. It also describes the interprofessional education initiative that Uniformed Services University is launching to help optimize U.S. military health care.

Job rotation has often been used in situations where the level of exposure cannot be reduced due to the characteristics of the job or through physical measures. However, the effectiveness of the job rotation strategy at preventing musculoskeletal complaints lacks adequate scientific data. A cluster randomized controlled trial will be used to investigate the effectiveness of job rotation to prevent musculoskeletal disorders in industrial workers. The randomized cluster was based in characteristics of production sectors. A total cluster will be 4 sectors, and 957 workers will be recruited from a textile industry and randomly allocated into intervention or control groups. Both groups will receive training on ergonomics guidelines. In addition, the intervention group will perform job rotation, switching between tasks with low, moderate, and high risk for musculoskeletal complaints. The primary outcome will be the number of working hours lost due to sick leave by musculoskeletal injuries recorded in employee administrative data bases. Secondary outcomes measured via survey include: body parts with musculoskeletal pain, the intensity of this pain, physical workload, fatigue, general health status, physical activity level, and work productivity. Secondary outcome measures will be assessed at baseline and after 3, 6, 9, and 12 months. The cost-effectiveness analysis will be performed from the societal and company perspective. Prevention of work-related musculoskeletal disorders is beneficial for workers, employers, and society. The results of this study will provide new information about the effectiveness of job rotation as a strategy to reduce work-related musculoskeletal disorders. NCT01979731, November 3, 2013.

Economic consequences of workplace injuries and illnesses: lost earnings and benefit adequacy.
Boden, L I; Galizzi, M
1999-11-01
This is the first study based on individual data to estimate earnings lost from virtually all reported workplace injuries and illnesses in a state. We estimated lost earnings from workplace injuries and illnesses occurring in Wisconsin in 1989-90, using workers' compensation data and 6 years of unemployment insurance wage data. We used regression techniques to estimate losses relative to a comparison group. The average present value of losses projected 10 years past the observed period is over $8,000 per injury. Women lose a greater proportion of their preinjury earnings than do men. Replacement of after-tax projected losses averages 64% for men and 50% for women. Overall, workers with compensated injuries and illnesses experienced discounted pre-tax losses projected to total over $530,000,000 (1994 dollars), with about 60% of after-tax losses replaced by workers' compensation. Generally, groups losing over eight weeks' work received workers' compensation benefits covering less than 40% of their losses. Copyright 1999 Wiley-Liss, Inc.

It is inevitable that some important specimens will become lost or damaged over time, conservation is therefore of vital importance. The Paluxy River dinosaur tracksite is among the most famous in the world. In 1940, Roland T. Bird described and excavated a portion of the site containing associated theropod and sauropod trackways. This excavated trackway was split up and housed in different institutions, and during the process a portion was lost or destroyed. We applied photogrammetric techniques to photographs taken by Bird over 70 years ago, before the trackway was removed, to digitally reconstruct the site as it was prior to excavation. The 3D digital model offers the opportunity to corroborate maps drawn by R.T. Bird when the tracksite was first described. More broadly, this work demonstrates the exciting potential for digitally recreating palaeontological, geological, or archaeological specimens that have been lost to science, but for which photographic documentation exists.

Negotiating targets with patients: choice of target in relation to occupational state.
Robinson, Sandra M; Walker, David J
2012-02-01
Following the recent National Institute for Health and Clinical Excellence guidance on the management of RA, we were interested to see if we could negotiate targets for treatment with patients in routine clinics, how they would express this and whether staying at work would be a target. One hundred RA patients were recruited. They were consecutive within clinics, but not all clinics were used. They were asked their understanding of the DAS score and a target for treatment negotiated. Any impact of the RA on their paid employment was then explored. Four participants were unable to specify a target for their RA. Negotiated targets were expressed as restricted activities and either as maintaining an activity (70) if the disease was stable, or regaining an activity (26) if the treatment was being increased. Targets were walking a distance for 50% of patients; leisure activities for 18%; domestic activities for 17%; work for 14% and personal care for 2%. For the 21 participants currently working, maintaining work was the target for 12, with 1 wishing to regain lost hours. No patient currently not working expressed returning to work as a target. There were some differences in targets between men and women. Patients are able to negotiate a target for their treatment, expressed as maintaining or regaining a physical activity. Work ceases to be a target once it is lost. Therefore, preventing loss of occupation is likely to be more effective than trying to regain it.

In this study, the main and interactive effects of obesity and age on functional performance were assessed during intermittent exertions involving the upper extremity. The prevalence of obesity has doubled over the past 30 years and this increase is associated with higher health care costs, rates of workplace injury, and lost workdays. Obesity and aging can modify job demands and affect worker capacity in terms of muscular and psychomotor function. However, there is a lack of empirical studies quantifying the work-relevant (or ergonomic) impacts related to task demands, capacities, and their potential imbalance. Eight obese and eight non-obese participants from each of two age groups (18-25 and 50-65 years) completed three endurance tasks involving fixed levels of task demands: hand grip, shoulder flexion, and a simulated assembly task using the upper extremity. Measures of functional performance including endurance, discomfort, motor control, and task performance were recorded for each of the task conditions. Endurance times were ∼60% longer for the non-obese group, and older participants had longer endurance times; however there was no evidence of interactive effects of obesity and age. Obesity also impaired functional performance, as indicated by higher rates of strength loss, increases in discomfort, and declines in task performance. These observed impairments may reflect underlying physiological differences among individuals who are obese, but that are independent of age. Obesity-related impairments may have implications for the design of work duration and demand level to prevent fatigue development for workers who are obese.
Years of life lost through Down's syndrome.
Jones, M B
1979-10-01
A congenital genetic condition does not act either as a cause of death or at the time of death only. Hence, years of life lost through such a conditon cannot be calculated in the same way as for a conventional cause of death. The main difference is that a cause of death acting at age x cuts off as many years of life as the dead person might otherwise have expected to live (life expectancy at age x), whereas a congenital genetic condition exposes an affected person to a different schedule of life-threatening risks from birth onwards. In the latter case, years of life lost is calculated as the difference in life expectancy at birth for affected and non-affected persons. This reasoning is worked out in algebraic form and then applied to Down's syndrome. The data base is provided by two large and recent studies, one in Massachusetts and the other in Denmark, of mortality rates among all cases of Down's syndrome, whether in an institution or not, born during a given period of years or living at a given point in time in a fixed geographical area. So calculated, years of life lost through Down's syndrome relative to the United States general population in 1970 was 53.6 years per 1000 livebirths. Prenatal mortality is also discussed.

To determine the mechanism of autoclave killing of Geobacillus stearothermophilus spores used in biological indicators (BIs) for steam autoclave sterilization, and rates of loss of spore viability and a spore enzyme used in BIs. Spore viability, dipicolinic acid (DPA) release, nucleic acid staining, α-glucosidase activity, protein structure and mutagenesis were measured during autoclaving of G. stearothermophilus spores. Loss of DPA and increases in spore core nucleic acid staining were slower than loss of spore viability. Spore core α-glucosidase was also lost more slowly than spore viability, although soluble α-glucosidase in spore preparations was lost more rapidly. However, spores exposed to an effective autoclave sterilization lost all viability and α-glucosidase activity. Apparently killed autoclaved spores were not recovered by artificial germination in supportive media, much spore protein was denatured during autoclaving, and partially killed autoclave-treated spore preparations did not acquire mutations. These results indicate that autoclave-killed spores cannot be revived, spore killing by autoclaving is likely by protein damage, and spore core α-glucosidase activity is lost more slowly than spore viability. This work provides insight into the mechanism of autoclave killing of spores of an organism used in BIs, and that a spore enzyme in a BI is more stable to autoclaving than spore viability. © 2016 The Society for Applied Microbiology.

The Layer-Oriented Simulation Tool (LOST) is a numerical simulation code developed for analysis of the performance of multiconjugate adaptive optics modules following a layer-oriented approach. The LOST code computes the atmospheric layers in terms of phase screens and then propagates the phase delays introduced in the natural guide stars' wave fronts by using geometrical optics approximations. These wave fronts are combined in an optical or numerical way, including the effects of wave-front sensors on measurements in terms of phase noise. The LOST code is described, and two applications to layer-oriented modules are briefly presented. We have focus on the Multiconjugate adaptive optics demonstrator to be mounted upon the Very Large Telescope and on the Near-IR-Visible Adaptive Interferometer for Astronomy (NIRVANA) interferometric system to be installed on the combined focus of the Large Binocular Telescope.
Avoid Workplace Injury through Ergonomics | Poster
Ergonomics is “the scientific study of people at work,” with the goal of reducing stress and eliminating injuries associated with overused muscles, bad posture, and repeated tasks, according to the Centers for Disease Control and Prevention (CDC). The Occupational Safety and Health Administration (OSHA) states that working ergonomically reduces muscle fatigue, increases productivity, and decreases the number and severity of work-related musculoskeletal disorders (MSDs). MSDs affect the muscles, nerves, and tendons, and are a leading cause of lost workdays due to injury or illness.

Processing remote sensing data is the epitome of computation, yet real-time collection systems remain human-labor intensive. Operator labor is consumed by both overhead tasks (cost) and value-added production (benefit). In effect, labor is taxed and then lost. When an operator comes on-shift, they typically duplicate setup work that their teammates have already performed many times. "Pass down" of state information can be difficult if security restrictions require total logouts and blank screens - hours or even days of valuable history and context are lost. As work proceeds, duplicative effort is common because it is typically easier for operators to "do it over" rather than share what others have already done. As we begin a major new system version, we are refactoring the user interface to reduce time and motion losses. Working with users, we are developing "click budgets" to streamline interface use. One basic function is shared clipboards to reduce the use of sticky notes and verbal communication of data strings. We illustrate two additional designs to share work: window copying and window sharing. Copying (technically, shallow or deep object cloning) allows any system user to duplicate a window and configuration for themselves or another to use. Sharing allows a window to have multiple users: shareholders with read-write functionality and viewers with read-only. These solutions would allow windows to persist across multiple shifts, with a rotating cast of shareholders and viewers. Windows thus become durable objects of shared effort and persistent state. While these are low-tech functions, the cumulative labor savings in a 24X7 crew position (525,000 minutes/year spread over multiple individuals) would be significant. New design and implementation is never free and these investments typically do not appeal to government acquisition officers with short-term acquisition-cost concerns rather than a long-term O and M (operations and maintenance) perspective. We share some successes in educating some officers, in collaboration with system users, about the human capital involved in operating the systems they are acquiring.

The objective of this study was to conduct a literature review examining predictors of lost-time injury, illness and disability (IID) in the workplace, with a focus on obesity as a predictor, and to evaluate the relationship between obesity and losttime IID. The study objective was also to analyze workplace disability prevention and interventions aimed at encouraging a healthy lifestyle among employees and reducing obesity and IID, as well as to identify research gaps. The search was conducted in several major online databases. Articles included in the review were published in English in peer-reviewed journals between January 2003 and December 2014, and were found to be of good quality and of relevance to the topic. Each article was critically reviewed for inclusion in this study. Studies that focused on lost-time IID in the workplace were reviewed and summarized. Workers in overweight and obese categories are shown to be at a higher risk of workplace IID, are more likely to suffer from lost-time IID, and experience a slower recovery compared to workers with a healthy body mass index (BMI) score. Lost-time IID is costly to an employer and an employee; therefore, weight reduction may financially benefit both - workers and companies. It was found that some companies have focused on developing interventions that aid reduction of weight and the practice of active lifestyle among their employees.

African Americans are disproportionately affected by hepatitis C (HCV) and are less likely to undergo HCV treatment. Underserved populations are especially at risk for experiencing health disparity. Aim. To identify reasons for HCV non-treatment among underserved African Americans in a large safetynet system. Medical records of HCV-infected African Americans evaluated at San Francisco General Hospital liver specialty clinic from 2006-2011 who did not receive HCV treatment were reviewed. Treatment eligibility and reasons for non-treatment were assessed. Factors associated with treatment ineligibility were assessed using logistic regression modeling. Among 118 patients, 42% were treatment ineligible, 18% treatment eligible, and 40% were undergoing work-up to determine eligibility. Reasons for treatment ineligibility were medical (54%), non-medical (14%), psychiatric (4%), or combined (28%). When controlling for age and sex, active/recent substance abuse (OR 6.65, p = 0.001) and having two or more medical comorbidities (OR 3.39, p = 0.005) predicted treatment ineligibility. Excluding those ineligible for treatment, 72% of all other patients were lost to follow-up; they were older (55 vs. 48 years, p = 0.01) and more likely to be undergoing work up to determine treatment eligibility (86 vs. 21%, p < 0.0001) than those not lost to follow-up. Medical comorbidities and substance abuse predicted HCV treatment ineligibility in underserved African Americans. Importantly, the majority of those undergoing work-up to determine HCV treatment eligibility were lost to follow-up. While newer anti-HCV agents may increase treatment eligibility, culturally appropriate interventions to increase compliance with evaluation and care remain critical to HCV management in underserved African Americans.

Nowadays, ca. 176,640 tons/year of silicon (Si) (>4N) is manufactured for Si wafers used for semiconductor industry. The production of the highly pure Si wafers inevitably includes very high-temperature steps at 1400–2000 °C, which is energy-consuming and environmentally unfriendly. Inefficiently, ca. 45–55% of such costly Si is lost simply as sawdust in the cutting process. In this work, we develop a cost-effective way to recycle Si sawdust as a high-performance anode material for lithium-ion batteries. By a beads-milling process, nanoflakes with extremely small thickness (15–17 nm) and large diameter (0.2–1 μm) are obtained. The nanoflake framework is transformed into a high-performance porous structure, named wrinkled structure, through a self-organization induced by lithiation/delithiation cycling. Under capacity restriction up to 1200 mAh g−1, the best sample can retain the constant capacity over 800 cycles with a reasonably high coulombic efficiency (98–99.8%). PMID:28218271

The soft x-ray spectrometer (SXS) was a cryogenic high-resolution x-ray spectrometer onboard the Hitomi (ASTRO-H) satellite that achieved energy resolution of 5 eV at 6 keV, by operating the detector array at 50 mK using an adiabatic demagnetization refrigerator (ADR). The cooling chain from room temperature to the ADR heat sink was composed of two-stage Stirling cryocoolers, a He4 Joule-Thomson cryocooler, and superfluid liquid helium and was installed in a dewar. It was designed to achieve a helium lifetime of more than 3 years with a minimum of 30 L. The satellite was launched on February 17, 2016, and the SXS worked perfectly in orbit, until March 26 when the satellite lost its function. It was demonstrated that the heat load on the helium tank was about 0.7 mW, which would have satisfied the lifetime requirement. This paper describes the design, results of ground performance tests, prelaunch operations, and initial operation and performance in orbit of the flight dewar and the cryocoolers.

Purpose Financial concerns represent a major stressor for families of children with cancer but remain poorly understood among those with terminally ill children. We describe the financial hardship, work disruptions, income loss, and coping strategies of families who lost children to cancer. Methods Retrospective cross-sectional survey of 141 American and 89 Australian bereaved parents whose children died between 1990 and 1999 and 1996 to 2004, respectively, at three tertiary-care pediatric hospitals (two American, one Australian). Response rate: 63%. Results Thirty-four (24%) of 141 families from US centers and 34 (39%) of 88 families from the Australian center reported a great deal of financial hardship resulting from their children's illness. Work disruptions were substantial (84% in the United States, 88% in Australia). Australian families were more likely to report quitting a job (49% in Australia v 35% in the United States; P = .037). Sixty percent of families lost more than 10% of their annual income as a result of work disruptions. Australians were more likely to lose more than 40% of their income (34% in Australia v 19% in the United States; P = .035). Poor families experienced the greatest income loss. After accounting for income loss, 16% of American and 22% of Australian families dropped below the poverty line. Financial hardship was associated with poverty and income loss in all centers. Fundraising was the most common financial coping strategy (52% in the United States v 33% in Australia), followed by reduced spending. Conclusion In these US and Australian centers, significant household-level financial effects of a child's death as a result of cancer were observed, especially for poor families. Interventions aimed at reducing the effects of income loss may ease financial distress. PMID:21205758

Characterized by pain symptoms, endometriosis affects women's productivity in their prime working years. To evaluate the effect of individual endometriosis symptoms on household chore and employment productivity as measured by presenteeism and absenteeism in a population survey of women with endometriosis. An online survey of U.S. women was conducted to evaluate the prevalence of endometriosis, as well as symptoms, demographics, and clinical characteristics of the respondents. Women aged 18-49 years (inclusive) with endometriosis completed the Health-related Productivity Questionnaire to assess presenteeism and absenteeism for employed and household work. Descriptive statistics were used to describe the sample, survey responses, and the effect of endometriosis symptom severity on household chore and employment productivity. Regression analyses were performed to examine the effect of individual endometriosis symptoms on employment and household productivity lost because of presenteeism and absenteeism. Of 59,411 women who completed the prevalence screener, 5,879 women (9.9%) met the inclusion criteria for completing the survey; 1,318 women (2.2%) reported endometriosis and at least 1 hour of scheduled household chores in the past 7 days. Of these, 810 women had least 1 hour of scheduled employment in the past 7 days. Mean age was 34.6 years (standard error [SE] ± 0.32); 77.2% of the women were white; 59.3% were married or in a civil union; and 59.1% were employed full or part time. Women with endometriosis had a weekly loss of an average of 5.3 hours (SE ± 0.4) because of employment presenteeism, 1.1 hours (SE ± 0.2) of employment absenteeism, 2.3 (SE ± 0.2) hours of household presenteeism, and 2.5 (SE ± 0.2) hours of household absenteeism. Hourly losses in employment and household chore productivity were significantly greater with increasing symptom severity (mild vs. severe: 1.9 vs. 15.8 total employment hours lost and 2.5 vs. 10.1 total household hours lost; P < 0.0001). Women who experienced 3 endometriosis symptoms concurrently lost a significantly greater number of employment hours because of absenteeism and presenteeism compared with those experiencing 1 or 2 symptoms (P < 0.001). Regression analyses showed that a range of endometriosis symptoms predicted employment and household losses because of presenteeism and absenteeism. There was a significant relationship between the number and patient-reported severity of endometriosis symptoms experienced and hours of employment and household productivity lost because of presenteeism and absenteeism. Study findings indicate a need for guidance strategies to help women and employers manage endometriosis so as to reduce productivity loss.

This paper addresses the problem of measuring and analyzing the performance of fine-grained parallel programs running on shared-memory multiprocessors. Such processors use locking (either directly in the application program, or indirectly in a subroutine library or the operating system) to serialize accesses to global variables. Given sufficiently high rates of locking, the chief factor preventing linear speedup (besides lack of adequate inherent parallelism in the application) is lock contention - the blocking of processes that are trying to acquire a lock currently held by another process. We show how a high-resolution, low-overhead clock may be used to measure both lockmore » contention and lack of parallel work. Several ways of presenting the results are covered, culminating in a method for calculating, in a single multiprocessing run, both the speedup actually achieved and the speedup lost to contention for each lock and to lack of parallel work. The speedup losses are reported in the same units, ''processor-equivalents,'' as the speedup achieved. Both are obtained without having to perform the usual one-process comparison run. We chronicle also a variety of experiments motivated by actual results obtained with our measurement method. The insights into program performance that we gained from these experiments helped us to refine the parts of our programs concerned with communication and synchronization. Ultimately these improvements reduced lock contention to a negligible amount and yielded nearly linear speedup in applications not limited by lack of parallel work. We describe two generally applicable strategies (''code motion out of critical regions'' and ''critical-region fissioning'') for reducing lock contention and one (''lock/variable fusion'') applicable only on certain architectures.« less
Calculation of the external work done during walking in very young children.
Schepens, Benedicte; Detrembleur, Christine

During walking, muscles must perform positive work to replace the energy lost from the body at each step, even if the average speed is constant and the terrain level. Young children have immature and irregular walk, but little is known about the effect of this walking pattern on the muscular external work done. Our objective was to measure using force platforms and the method of Cavagna (J Appl Physiol 39:174-179, 1975) the amount of muscular external work done by 1-year-old-, 4-year-old children and adults during walking. We were interested to quantify the approximation made by measuring only the positive external work done and assuming it reflects the external work done. After having confirmed that young children were not able to walk at a constant average speed over a complete number of steps, we showed the effect of the selection of trials by measuring the external work done assuming the amount of positive work done is equal to the negative work done (supposing there is no acceleration or deceleration over a complete number of steps). We observed that even if young subjects were not able to walk at a constant lateral speed over a complete number of steps, the amount of work done to maintain the center of mass movements in the transversal plane is not more than 10% of the external positive work done. This observational study points out that the measurement of external work, a good summary indicator for the gait mechanics, may be interpreted precociously when the population studied walked irregularly.

[Social psychiatry in the field of contrasting context between psychiatry and Social Medicine].
Dietrich, Sandra; Born, Anja; Holzinger, Anita
2006-11-01
There has been a discussion going on that Social Psychiatry has entered a state of crisis in terms of its socio-scientific roots. Little is known, however, about its relationship to Social Medicine. The question is whether Social Psychiatry, having grown apart from Sociology, has also lost its scientific relation to Social Medicine. A systematic literature analysis of all works published in "Psychiatrische Praxis" - PP and "Das Gesundheitswesen"--GHW in the years 2004/2005 was done. All works concerning Social Psychiatry were analysed. The same procedure was applied to all abstracts, posters and presentations for the annual meetings of the German Society of Social Medicine and Prevention (DGSMP). 10 % off all articles published in GHW and 97 % in PP address issues of Social Psychiatry. Apart from similarities in terms of their theoretical, practical and institutional background and the research methods applied, there are a number of differences. Social Psychiatry has not lost its scientific relation to Social Medicine, however, the scientific cooperation between the two needs to be intensified.

Determine lost work time and job attrition for incident breast cancer (BC). The cases were employed women, aged 18 to 64, with BC identified by a validated algorithm between 1999 and 2005, from claims (MarketScan) and attendance databases. Controls without cancer were matched 3:1 on age, comorbidity, and index year. First-year mean disability days were 60 (cases, N = 880) versus 5 (controls, N = 2640) (P < 0.001). The first-year disability costs were $4900 for cases versus $385 for controls (P < 0.001). In years 2 through 4, the disability days and associated costs were similar for the cases versus controls. After 4 years, 56.4% of cases were still enrolled in the employer-sponsored insurance programs compared to 6.5% of controls (P < 0.001). The lost work associated with BC is substantial in the first year after diagnosis. Employee retention is much higher for BC cases versus controls.

The applicability of plant-based life support systems has traditionally suffered from the limitations imposed by the high energy demand of controlled environment growth chambers. Theme types of systems are typically less than 2% efficient at converting electrical energy into biomass. The remaining 98% of supplied energy is converted to thermal energy. Traditionally this thermal energy is discharged to the ambient environment as waste heat. This paper describes an energy efficient plant-based life support system which has been designed for use at the Amundsen-Scott South Pole Station. At the South Pole energy is not lost to the environment. What is lost is the ability to extract useful work from it. The CELSS Antarctic Analog Program (CAAP) has developed a system which is designed to extract useful work from the waste thermal energy generated from plant growth lighting systems. In the CAAP system this energy is used to purify Station Sewage.

During germination, orthodox seeds become gradually intolerant to desiccation, and for this reason, they are a good model for recalcitrance studies. In the present work, physiological, biochemical, and ultrastructural aspects of the desiccation tolerance were characterized during the germination process of Anadenanthera colubrina seeds. The seeds were imbibed during zero (control), 2, 8, 12 (no germinated seeds), and 18 hours (germinated seeds with 1 mm protruded radicle); then they were dried for 72 hours, rehydrated and evaluated for survivorship. Along the imbibition, cytometric and ultrastructural analysis were performed, besides the extraction of the heat-stable proteins. Posteriorly to imbibition and drying, the evaluation of ultrastructural damages was performed. Desiccation tolerance was fully lost after root protrusion. There was no increase in 4C DNA content after the loss of desiccation tolerance. Ultrastructural characteristics of cells from 1mm roots resembled those found in the recalcitrant seeds, in both hydrated and dehydrated states. The loss of desiccation tolerance coincided with the reduction of heat-stable proteins.

To evaluate a program to reduce musculoskeletal disability-related absenteeism at a North American manufacturing facility. Staged communication and educational interventions targeting physicians to improve care of musculoskeletal conditions and reduce related absenteeism. The program was implemented in three 1-year stages. The first stage required physicians to complete assessment forms for employees claiming disability because of musculoskeletal injuries. The second stage added physician education programs focusing on current clinical guidelines. The third stage incorporated local physician education about the facility's onsite physical therapy program. Annual number of work-related injuries, days lost per injury and per scheduled full-time-equivalent (FTE) employee, light-duty days per injury, average annual indemnity per FTE, indemnity per injury, medical costs per FTE, and medical costs per injury were examined to determine the program's effectiveness. Overall productivity improved by a mean of 12.5 days per injured employee. Mean days lost per work-related injury decreased from 35.1 to 27.6. Number of light-duty days increased from 6.1 to 11.1 per work-related injury. Mean annual indemnity per work-related injury decreased from $9327 to $4493; mean annual medical costs per work-related injury decreased from $4848 to $2679. The annual incidence of musculoskeletal injuries declined by up to 50%. This intervention was associated with reduced musculoskeletal disability-related absenteeism and increased productivity. The program reduced medical costs per work-related injury and improved the company's communications and relationship with local physicians.

1997-12-01
A survey was conducted to determine the effects of biting and stinging arthropods on military personnel, operations, and training. Nearly 70% of respondents reported experiencing problems attributable to arthropods. Arthropods obstructed movement and field position, prevented concealment and cover, disrupted maneuvers, and caused panic. Twenty percent of respondents reported attendance at sick call for treatment of bites or stings, and 4% were hospitalized or assigned to quarters. Median lost time was 2 days. Bee, wasp, and ant stings and spider and chigger bites were the most frequent causes of lost time. Additional training on biting and stinging arthropods, use of repellents and other personal protective measures, first aid for bites and stings, and conditions requiring medical attention is needed in field units to enhance mission performance and reduce time lost because of arthropods. Materials for treatment of bites and stings should be included in first-aid kits issued for field use.
[Imputation methods for missing data in educational diagnostic evaluation].
Fernández-Alonso, Rubén; Suárez-Álvarez, Javier; Muñiz, José

In the diagnostic evaluation of educational systems, self-reports are commonly used to collect data, both cognitive and orectic. For various reasons, in these self-reports, some of the students' data are frequently missing. The main goal of this research is to compare the performance of different imputation methods for missing data in the context of the evaluation of educational systems. On an empirical database of 5,000 subjects, 72 conditions were simulated: three levels of missing data, three types of loss mechanisms, and eight methods of imputation. The levels of missing data were 5%, 10%, and 20%. The loss mechanisms were set at: Missing completely at random, moderately conditioned, and strongly conditioned. The eight imputation methods used were: listwise deletion, replacement by the mean of the scale, by the item mean, the subject mean, the corrected subject mean, multiple regression, and Expectation-Maximization (EM) algorithm, with and without auxiliary variables. The results indicate that the recovery of the data is more accurate when using an appropriate combination of different methods of recovering lost data. When a case is incomplete, the mean of the subject works very well, whereas for completely lost data, multiple imputation with the EM algorithm is recommended. The use of this combination is especially recommended when data loss is greater and its loss mechanism is more conditioned. Lastly, the results are discussed, and some future lines of research are analyzed.

Study Objectives: Insomnia is a chronic condition with significant burden on health care and productivity costs. Despite this recognized burden, very few studies have examined associations between insomnia severity and healthcare and productivity costs. Design: A retrospective study linking health claims data with a telephone survey of members of a health plan in the Midwestern region of the United States. Participants: The total healthcare costs study sample consisted of 2086 health plan members who completed the survey and who had complete health claims data. The productivity costs sample consisted of 1329 health plan members who worked for pay—a subset of the total healthcare costs sample. Measurements: Subjects' age, gender, demographic variables, comorbidities, and total health care costs were ascertained using health claims. Insomnia severity and lost productivity related variables were assessed using telephone interview. Results: Compared with the no insomnia group, mean total healthcare costs were 75% larger in the group with moderate and severe insomnia ($1323 vs. $757, P < 0.05). Compared with the no insomnia group, mean lost productivity costs were 72% larger in the moderate and severe insomnia group ($1739 vs. $1013, P < 0.001). Chronic medical comorbidities and psychiatric comorbidities were positively associated with health care cost. In contrast, psychiatric comorbidities were associated with lost productivity; while, medical comorbidities were not associated with lost productivity. Conclusions: Health care and lost productivity costs were consistently found to be greater in moderate and severe insomniacs compared with non-insomniacs. Factors associated with lost productivity and health care costs may be fundamentally different and may require different kinds of interventions. Future studies should focus on better understanding mechanisms linking insomnia to healthcare and productivity costs and to understanding whether developing targeted interventions will reduce these costs.

5 member companies of the Botswana Business Coalition on AIDS (BBCA) in the manufacturing, transport, distribution, and finance sectors participated in a pilot study of the impact of HIV/AIDS upon companies in Botswana. The study was conducted on behalf of the Botswana National Task Force on AIDS in the Workplace, and involved both management and employee teams from the participating companies. While HIV is usually not spread in the course of work, company characteristics such as having a mobile, well-paid work force, poor housing, or a high community HIV prevalence may increase employees' susceptibility to contracting and transmitting HIV. Companies' susceptibility to the impact of the HIV/AIDS epidemic was assessed through interviews with management and employees. The transport sector was at highest risk, while the finance sector was at lowest risk. Assessing the HIV/AIDS impact, lost labor time due to sick leave, the costs of other benefits, future HIV/AIDS cases and health costs, and regional comparisons of the HIV/AIDS impact are considered. The most significant HIV/AIDS-related cost to the businesses in this study is the cost of lost work time due to employee illness.
The effect of spiked boots on logger safety, productivity and workload.
Kirk, P; Parker, R
1994-04-01
Analysis of 1657 lost-time logging accidents in the New Zealand logging industry (1985-1991) indicates that 17.5% were as a result of slips, trips and falls and a total of 2870 days were lost. Most (56%) of these slipping, tripping and falling accidents occurred in the felling and delimbing phase of the logging operation, where 37% of the workforce are employed. In an attempt to reduce the number of slipping injuries to loggers employed in felling and delimbing, a study of the effectiveness of spike-soled (caulk) boots was undertaken. Four loggers were intensively observed at work, by continuous time-study methods, while wearing their conventional rubber-soled boots and then spike-soled boots. The number of slips, work methods used, physiological workload and productivity were compared for loggers wearing the two footwear types. Results indicated that spike-soled boots were associated with a significant reduction in the frequency of slips and had no adverse effect on work methods, physiological workload or productivity. Spike-soled boots are now being promoted for use by loggers in New Zealand as a simple method to reduce slipping, tripping and falling accidents.
A feature refinement approach for statistical interior CT reconstruction

Interior tomography is clinically desired to reduce the radiation dose rendered to patients. In this work, a new statistical interior tomography approach for computed tomography is proposed. The developed design focuses on taking into account the statistical nature of local projection data and recovering fine structures which are lost in the conventional total-variation (TV)—minimization reconstruction. The proposed method falls within the compressed sensing framework of TV minimization, which only assumes that the interior ROI is piecewise constant or polynomial and does not need any additional prior knowledge. To integrate the statistical distribution property of projection data, the objective function is built under the criteria of penalized weighed least-square (PWLS-TV). In the implementation of the proposed method, the interior projection extrapolation based FBP reconstruction is first used as the initial guess to mitigate truncation artifacts and also provide an extended field-of-view. Moreover, an interior feature refinement step, as an important processing operation is performed after each iteration of PWLS-TV to recover the desired structure information which is lost during the TV minimization. Here, a feature descriptor is specifically designed and employed to distinguish structure from noise and noise-like artifacts. A modified steepest descent algorithm is adopted to minimize the associated objective function. The proposed method is applied to both digital phantom and in vivo Micro-CT datasets, and compared to FBP, ART-TV and PWLS-TV. The reconstruction results demonstrate that the proposed method performs better than other conventional methods in suppressing noise, reducing truncated and streak artifacts, and preserving features. The proposed approach demonstrates its potential usefulness for feature preservation of interior tomography under truncated projection measurements.

To present the results of the burden of disease, injuries and risk factors in Mexico from 1990 to 2010 for the principal illnesses, injuries and risk factors by sex. A secondary analysis of the study results published by the Global Burden of Disease 2010 for Mexico performed by IHME. In 2010, Mexico lost 26.2 million of Disability adjusted live years (DALYs), 56 % were in male and 44 % in women. The main causes of DALYs in men are violence, ischemic heart disease and road traffic injuries. In the case of women the leading causes are diabetes, chronic kidney disease and ischemic heart diseases. The mental disorders and musculoskeletal conditions concentrate 18% of health lost. The risk factors that most affect men in Mexico are: alcohol consumption, overweight/obesity, high blood glucose levels and blood pressure and tobacco consumption (35.6 % of DALYs lost). In women, overweight and obesity, high blood sugar and blood pressure, lack of physical activity and consumption of alcohol are responsible for 40 % of DALYs lost. In both sexes the problems with diet contribute 12% of the burden. The epidemiological situation in Mexico, demands an urgent adaptation and modernization of the health system.

Patients and caregivers participated in a diary study for 90 or more days or until patients experienced four bleeding episodes. All bleed treatments, interference with daily activities, and quality-of-life assessments were captured in daily records. Patients and caregivers reported planned workdays or school days eligible to be "lost" so as to differentiate from days lost because of disability or nonworking status, weekends, and vacations. Diaries were completed for 39 patients (18 adults and 21 children). Bleeding episodes that continued for 3 or more days (16.4%) accounted for most of the major changes to family plans. For the 38 patients with bleeding episodes, 47% of 491 bleed days fell on planned workdays or school days; the remainder fell on weekends, holidays, or nonworkdays or non-school days and therefore did not count as "lost days." Patients reported a loss of productivity on a greater percentage of eligible bleed days than did caregivers (3.9% vs. 0.8%, respectively). Patients and caregivers reported 13.5%/9.3% fully missed and 3.5%/7.6% partially missed days. This study demonstrated that in hemophilia with inhibitors, bleeding episodes interfere with the daily activities of patients and their caregivers. Furthermore, documenting only lost days underestimated the impact of bleeding episodes because of the high percentage of days without planned work or school.

Identification of Work-Related Musculoskeletal Disorders in Mining
Weston, Eric; Pollard, Jonisha P.
2016-01-01
Work-related musculoskeletal disorder (WMSD) prevention measures have been studied in great depth throughout various industries. While the nature and causes of these disorders have been characterized in many industries, WMSDs occurring in the U.S. mining sector have not been characterized for several years. In this report, MSHA accident/injury/illness data from 2009 to 2013 were characterized to determine the most frequently reported WMSDs in the U.S. mining sector. WMSDs were most frequently reported in workers with less than 5 years or more than 20 years of mining experience. The number of days lost from work was the highest for shoulder and knee injuries and was found to increase with worker age. Underground and surface coal, surface stone and stone processing plants experienced the greatest number of WMSDs over the period studied. WMSDs were most commonly caused by an employee suffering from an overexertion, falls or being struck by an object while performing materials handling, maintenance and repair tasks, getting on or off equipment or machines, and walking or running. The injury trends presented should be used to help determine the focus of future WMSD prevention research in mining. PMID:27294012
Recycling energy to restore impaired ankle function during human walking.
Collins, Steven H; Kuo, Arthur D
2010-02-17
Humans normally dissipate significant energy during walking, largely at the transitions between steps. The ankle then acts to restore energy during push-off, which may be the reason that ankle impairment nearly always leads to poorer walking economy. The replacement of lost energy is necessary for steady gait, in which mechanical energy is constant on average, external dissipation is negligible, and no net work is performed over a stride. However, dissipation and replacement by muscles might not be necessary if energy were instead captured and reused by an assistive device. We developed a microprocessor-controlled artificial foot that captures some of the energy that is normally dissipated by the leg and "recycles" it as positive ankle work. In tests on subjects walking with an artificially-impaired ankle, a conventional prosthesis reduced ankle push-off work and increased net metabolic energy expenditure by 23% compared to normal walking. Energy recycling restored ankle push-off to normal and reduced the net metabolic energy penalty to 14%. These results suggest that reduced ankle push-off contributes to the increased metabolic energy expenditure accompanying ankle impairments, and demonstrate that energy recycling can be used to reduce such cost.

Efforts to improve performance in the workplace with respect to positive mental health have increased, and cognitive behavioral therapy (CBT) has recently attracted attention as an intervention measure to this end. Here, we conducted a randomized controlled trial to evaluate the effectiveness of a brief training program on CBT for improving work performance of employees. The participants were employees of an electric company in Japan. The intervention consisted of 1 group session of CBT (120 min) and web-based CBT homework for 1 month. We evaluated employees in both the intervention and control groups at baseline and follow-up after three months. The main outcome was work performance, which was evaluated by a subjective score from 1 to 10. The secondary outcome was self-evaluation of cognitive flexibility. Analyses were conducted based on ITT. In the intervention group, 84 participants attended the group session, with 79 subsequently completing at least 1 instance of online homework. ITT analysis showed that the subjective performance of the intervention group was significantly improved compared with that of the control group (1.47 vs. 0.69, mean difference 0.78 [95% confidence interval {CI}, 0.05 to 1.51], Cohen's d=0.31). The ability to recognize dysfunctional thinking patterns and change them to positive ones significantly improved in the intervention group compared to the control group (0.71 vs. 0.26, mean difference 0.45 [95% CI 0.06 to 0.83], d=0.33). However, after adjustment for baseline scores, no significant difference was observed. The ability to view a situation from multiple perspectives and expand one's repertoire of thought patterns in the intervention group also significantly improved (0.83 vs. 0.35, mean difference 0.48 [95% CI 0.35 to 0.95], d=0.29), but here again, significance was lost after adjusting for baseline scores. Our results suggest that a brief training program that combines a group CBT session with web-based CBT homework improved subjective work performance. In addition, this program might help improve employees' cognitive flexibility.

One of the applications of the Neurofeedback methodology is peak performance in sport. The protocols of the neurofeedback are usually based on an assessment of the spectral parameters of spontaneous EEG in resting state conditions. The aim of the paper was to study whether the intensive neurofeedback training of a well-functioning Olympic athlete who has lost his performance confidence after injury in sport, could change the brain functioning reflected in changes in spontaneous EEG and event related potentials (ERPs). The case is presented of an Olympic athlete who has lost his performance confidence after injury in sport. He wanted to resume his activities by means of neurofeedback training. His QEEG/ERP parameters were assessed before and after 4 intensive sessions of neurotherapy. Dramatic and statistically significant changes that could not be explained by error measurement were observed in the patient. Neurofeedback training in the subject under study increased the amplitude of the monitoring component of ERPs generated in the anterior cingulate cortex, accompanied by an increase in beta activity over the medial prefrontal cortex. Taking these changes together, it can be concluded that that even a few sessions of neurofeedback in a high performance brain can significantly activate the prefrontal cortical areas associated with increasing confidence in sport performance.

In 2004, Canada's First Ministers committed to reforms that would shape the future of the Canadian healthcare landscape. These agreements included commitments to improved performance reporting within the primary healthcare system. The aim of this paper was to review the state of primary healthcare performance reporting after the public reporting mandate agreed to a decade ago in the Action Plan for Health System Renewal of 2003 expired. A grey literature search was performed to identify reports released by the governmental and independent reporting bodies across Canada. No province, or the federal government, met their performance reporting obligations from the 2004 accords. Although the indicators required to report on in the 2004 Accord no longer reflect the priorities of patients, policy makers and physicians, provinces are also failing to report on these priorities. Canada needs better primary healthcare performance reporting to enable accountability and improvement within and across provinces. Despite the national mandate to improve public health system reporting, an opportunity to learn from the diverse primary healthcare reforms, underway across Canada for the past decade, has already been lost.

The cost of lost productivity due to fetal alcohol spectrum disorder-related premature mortality.
Easton, Brian; Burd, Larry; Sarnocinska-Hart, Anna; Rehm, Jürgem; Popova, Svetlana
2015-01-01
Individuals with Fetal Alcohol Spectrum Disorder (FASD) have increased mortality as compared to the general population. To estimate the productivity losses due to premature mortality of individuals with FASD in Canada in 2011. A demographic approach with a counterfactual scenario in which nobody in Canada is born with FASD was used. Population estimates were calculated using data on the labour force, unemployment rate, and average weekly wage obtained from Statistics Canada. The number of FASD-related deaths, coded in the International Classification of Diseases, version 10, was estimated based on data from Statistics Canada and pooled prevalence estimates of the major disease conditions associated with FASD were obtained from a meta-analysis. The estimates of FASD-related mortality rates served as a basis for the length of working life span estimation. Once the number of working years lost to premature deaths was derived, productivity losses were computed. It was estimated that in total 327 individuals with FASD aged 20 to 69 (almost twice as many men as women) died in Canada in 2011. As a result, there were 2,877 years of potential employment lost, which translated to a loss ranging from $88 million to $126 million. This amount represents the increase in national income, had there been no premature mortality from FASD and the workers with FASD had been typical members of the labour force (without compromised productivity due to FASD). The estimates of productivity losses further reinforce the value of FASD prevention as a primary strategy.

Disease-specific reductions in patient productivity can lead to substantial economic losses to society. The purpose of this study was to: 1) define the annual productivity cost for a patient with refractory chronic rhinosinusitis (CRS) and 2) evaluate the relationship between degree of productivity cost and CRS-specific characteristics. Prospective, multi-institutional, observational cohort study. The human capital approach was used to define productivity costs. Annual absenteeism, presenteeism, and lost leisure time was quantified to define annual lost productive time (LPT). LPT was monetized using the annual daily wage rates obtained from the 2012 U.S. National Census and the 2013 U.S. Department of Labor statistics. A total of 55 patients with refractory CRS were enrolled. The mean work days lost related to absenteeism and presenteeism were 24.6 and 38.8 days per year, respectively. A total of 21.2 household days were lost per year related to daily sinus care requirements. The overall annual productivity cost was $10,077.07 per patient with refractory CRS. Productivity costs increased with worsening disease-specific QoL (r = 0.440; p = 0.001). Results from this study have demonstrated that the annual productivity cost associated with refractory CRS is $10,077.07 per patient. This substantial cost to society provides a strong incentive to optimize current treatment protocols and continue evaluating novel clinical interventions to reduce this cost. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

Losing an only child: the one-child policy and elderly care in China.
Song, Yu
2014-05-01
China has had the one-child policy for more than 30 years. It reduced China's population growth within a short period of time and promoted economic development. However, it has also led to difficulties, and this paper focuses on those which pertain to ageing and losing one's only child. Approximately one million families have lost their only child in China. They suffer mentally and physically, and sometimes face social stigma and economic loss. What worries them most, however, is elderly care, which has become a severe crisis for the families who have lost their only children. This article draws upon several qualitative studies and 12 cases reported by the Chinese media in 2012 and 2013, and existing laws and policies for supporting those who have lost only children. It also analyses the current elderly care situation facing these families. The Chinese government has recognized the predicament and provides some help, which is increasing but is still not always adequate. To both sustain China's economic development and limit population growth, it is essential for the government to reform the one-child policy and provide a comprehensive support system for the families who have lost their only children, including financial relief and elderly care, and work to reduce stigma against these families.

OBJECTIVE Research on the workplace costs of mood disorders has focused largely on major depressive episodes (MDE). Bipolar disorder (BPD) has been overlooked both by failing to distinguish MDE due to major depressive disorder (MDD) versus BPD and by failing to evaluate the workplace costs of mania and hypomania. METHOD The National Comorbidity Survey Replication (NCS-R) assessed DSM-IV MDD and BPD with the WHO Composite International Diagnostic Interview (CIDI) and assessed work impairment with the WHO Health and Work Performance Questionnaire (HPQ). Regression analysis of MDD and BPD predicting HPQ among workers (n = 3378) was used to estimate the workplace costs of mood disorders. RESULTS 1.1% of workers met CIDI criteria for 12-month BPD (bipolar I or bipolar II) and 6.4% for 12-month MDD. BPD was associated with 65.5 and MDD with 27.2 annual lost workdays per ill worker. Subgroup analysis showed that the higher work loss associated with BPD than MDD is due to more severe and persistent MDE in BPD than MDD rather than to stronger effects of mania-hypomania than depression. Annual human capital loss per ill worker was estimated at $9619 for BPD and $4426 for MDD. Annual projections to the US labor force were $14.1 billion for BPD and $36.6 billion for MDD. CONCLUSIONS Employer interest in the workplace costs of mood disorders should be broadened beyond MDD to include BPD. Effectiveness trials are needed to study the return on employer investment of coordinated programs for workplace screening and treatment of BPD and MDD. PMID:16946181

Gas condensate reservoirs usually exhibit complex flow behaviors because of propagation response of pressure drop from the wellbore into the reservoir. When reservoir pressure drops below the dew point in two phase flow of gas and condensate, the accumulation of large condensate amount occurs in the gas condensate reservoirs. Usually, the saturation of condensate accumulation in volumetric gas condensate reservoirs is lower than the critical condensate saturation that causes trapping of large amount of condensate in reservoir pores. Trapped condensate often is lost due to condensate accumulation-condensate blockage courtesy of high molecular weight, heavy condensate residue. Recovering lost condensate most economically and optimally has always been a challenging goal. Thus, gas cycling is applied to alleviate such a drastic loss in resources. In gas injection, the flooding pattern, injection timing and injection duration are key parameters to study an efficient EOR scenario in order to recover lost condensate. This work contains sensitivity analysis on different parameters to generate an accurate investigation about the effects on performance of different injection scenarios in homogeneous gas condensate system. In this paper, starting time of gas cycling and injection period are the parameters used to influence condensate recovery of a five-spot well pattern which has an injection pressure constraint of 3000 psi and production wells are constraint at 500 psi min. BHP. Starting injection times of 1 month, 4 months and 9 months after natural depletion areapplied in the first study. The second study is conducted by varying injection duration. Three durations are selected: 100 days, 400 days and 900 days. In miscible gas injection, miscibility and vaporization of condensate by injected gas is more efficient mechanism for condensate recovery. From this study, it is proven that the application of gas cycling on five-spot well pattern greatly enhances condensate recovery preventing financial, economic and resource loss that previously occurred.

The present exploratory project represents a cross-sectional study designed to determine the percentage of people reporting significant symptoms of complicated grief (CG) and/or posttraumatic stress disorder (PTSD) in response to the death of companion pets/animals. Human participants (N = 106) were sampled from a veterinary clinic. Fifty-two percent of participants had lost one to three pets from natural causes, 60% had never lost a pet to euthanasia, and 37% had lost one to three pets to euthanasia. The study suggests that many people experience significant attachment to their pets/animals and experience significant features of grief reactions (about 20%) after the death of a pet/animal. However, the percentage of people experiencing major pathological disruption is relatively low (<5%-12%). Thus, subclinical levels of grief and sadness are relatively common human responses to the death of companion pets/animals and last 6 months or more for about 30% of those sampled. Severe pathological reactions do occur but are quite rare among human survivors. Implications for mental health clinicians working with affected populations are discussed.
Economic impact of musculoskeletal disorders (MSDs) on work in Europe.
Bevan, Stephen
2015-06-01
Musculoskeletal disorders (MSDs) are the leading cause of work disability, sickness absence from work, 'presenteeism' and loss of productivity across all the European Union (EU) member states. It is estimated that the total cost of lost productivity attributable to MSDs among people of working age in the EU could be as high as 2% of gross domestic product (GDP). This paper examines the available evidence on the economic burden of MSDs on work across Europe and highlights areas of policy, clinical and employment practice which might improve work outcomes for individuals and families and reduce the economic and social costs of MSDs.

Background: Traumatic Brain Injuries (TBIs) as a result of traffic accidents are one of the major causes of deaths, which lead to the loss of individuals’ productive and working years of life. Objectives: This study aimed to calculate the economic burden of traumatic brain injuries in fatal crashes at Shahid Rajaei Trauma Hospital, Shiraz, Iran for a period of five years. Patients and Methods: In this descriptive, cross-sectional study the population included people who had died as a result of TBIs during 2009 to 2013 in Shiraz Shahid Rajaei Trauma Hospital. Cost and demographic data were obtained from the participants’ medical records using data gathering forms, and some other information was also collected via telephone calls to the victims’ families. Economic burden of TBIs due to traffic accidents, which led to death, was estimated using the human capital as direct costs of treatment, and the number of potential years of life lost and lost productivity as indirect costs. Results: Deaths resulting from TBIs due to traffic accidents in Shiraz imposed 6.2 billion Rials (511000 USD) of hospital costs, 6390 potential years of life lost, and 506 billion Rials (20 million USD) of productivity lost. In the present study, the mean age of the individuals who died was 38.4 ± 19.41 and the productivity lost per capita was 1.8 billion Rials (73000 USD). Conclusions: The findings of this study indicated that the economic burden of TBIs was high in fatal accidents in Fars Province so that it was equivalent to 0.00011% of Iran’s Gross Domestic Product (GDP) in 2013. Therefore, more attention has to be paid to the rules to prevent the fatal accidents. PMID:25834791

The study area (see index map of Idaho), part of the Big Lost River drainage basin, is at the northern side of the eastern Snake River Plain. The lower Big Lost River Valley extends from the confluence of Antelope Creek and the Big Lost River to about 4 mi south of Arco and encompasses about 145 mi2 (see map showing water-level contours). The study area is about 18 mi long and, at its narrowest, 4 mi wide. Arco, Butte City, and Moore, with populations of 1,016, 59, and 190, respectively, in 1990, are the only incorporated towns. The entire study area, except the extreme northwestern part, is in Butte City. The study area boundary is where alluvium and colluvium pinch out and abut against the White Knob Mountains (chiefly undifferentiated sedimentary rock with lesser amounts of volcanic rock) on the west and the Lost River Range (chiefly sedimentary rock) on the east. Gravel and sand in the valley fill compose the main aquifer. The southern boundary is approximately where Big Lost River valley fill intercalates with or abuts against basalt of the Snake River Group. Spring ground-water levels and flow in the Big Lost River depend primarily on temperature and the amount and timing of precipitation within the entire drainage basin. Periods of abundant water supply and water shortages are, therefore, related to the amount of annual precipitation. Surface reservoir capacity in the valley (Mackay Reservoir, about 20 mi northwest of Moore) is only 20 percent of the average annual flow of the Big Lost River (Crosthwaite and others, 1970, p. 3). Stored surface water is generally unavailable for carryover from years of abundant water supply to help relieve drought conditions in subsequent years. Many farmers have drilled irrigation wells to supplement surface-water supplies and to increase irrigated acreage. Average annual flow of the Big Lost River below Mackay Reservoir near Mackay (gaging station 13127000, not shown) in water years 1905, 1913-14, and 1920-90 was about 224,600 acre-ft; average annual flow of the Big Lost River near Arco (gaging station 13132500; see map showing water-level contours) in water years 1947-61, 1967-80, and 1983-90 was about 79,000 acre-ft (Harenberg and others, 1991, p. 254-255). Moore Canal and East Side Ditch divert water from the Big Lost River at the Moore Diversion, 3 mi north of Moore (see map showing water-level contours) and supply water for irrigation near the margins of the valley. When water supply is average or greater, water in the Big Lost River flows through the study area and onto the Snake River Plain, where it evaporates or infiltrates into the Snake River Plain aquifer. When water supply is below average, water in the Big Lost River commonly does not reach Arco; rather, it is diverted for irrigation in the interior of the valley, evaporates, or infiltrates to the valley-fill aquifer. This report describes the results of a study by the U.S. Geological Survey, in cooperation with the Idaho Department of Water Resources, to collect hydrologic data needed to help address water-supply problems in the Big Lost River Valley. Work involved (1) field inventory of 81 wells, including 46 irrigation wells; (2) measurement of water levels in 154 wells in March 1991; (3) estimation of annual ground-water pumpage for irrigation from 1984 through 1990; and (4) analysis of results of an aquifer test conducted southwest of Moore. All data obtained during this study may be inspected at the U.S. Geological Survey, Idaho District office, Boise.

Fable or fact?: did Janet really come to repudiate his dissociation theory?
Dorahy, Martin J; van der Hart, Onno
2006-01-01
Commencing in the late 1880s Pierre Janet developed the most complete theory of dissociation of his time. It has been suggested that Janet later repudiated his belief in dissociation theory (e.g., Hacking, 1995). Recently this viewpoint has been cited to support skepticism in dissociative identity disorder and researchers and clinicians of dissociation may be faced with such suggestions to challenge their work. The veracity of whether Janet actually recanted, or even lost interest in his dissociation theory is investigated through an examination of his later writings. Although Janet expanded his theoretical interests well beyond phenomena accounted for by dissociation, there is no evidence to indicate he renounced or lost confidence in his dissociation theory.

To understand the impact of the early years of RA on all aspects of work productivity, and determine how this is related to clinical markers. Previous research on work productivity has examined predominantly early retirement and absenteeism. The impact of reduced work performance (presenteeism) and activity impairment is less well understood in early RA populations. Working patients enrolled in an RA inception cohort were recruited into a nested study. A questionnaire incorporating the Work Productivity and Activity Impairment (WPAI) instrument was administered with a number of clinical outcomes, including the Multidimensional Health Assessment Questionnaire (MD-HAQ) and scales for pain, fatigue and patient assessment of disease patient global assessment (PtGA). Analysis included 150 RA patients, with the mean age at onset being 48 years (s.d. 10 years) and disease duration from symptom onset being 49 months. Patients had relatively mild disease: MD-HAQ (0.6), pain (3.6), PtGA (3.6) and fatigue (4.6). Of the 92% patients working for pay, 19% reported missing work (absenteeism) in the past week due to their health, accounting for 46% of their working time. Even while at work, ∼25% of actual hours was lost due to poor health, while outside work 33% of patients' regular daily activities were prevented. In multivariate analyses, disease severity was associated with the presence of absenteeism, presenteeism and activity impairment. Patients able to self-schedule their work had lower presenteeism and activity impairment. Productivity loss is common in patients in the first years of RA who are in paid work and was associated with work characteristics and adverse clinical outcomes.

This report describes the evaluation, design, and implementation of a DOE funded CO{sub 2} pilot project in the Lost Hills Field, Kern County, California. The pilot consists of four inverted (injector-centered) 5-spot patterns covering approximately 10 acres, and is located in a portion of the field, which has been under waterflood since early 1992. The target reservoir for the CO{sub 2} pilot is the Belridge Diatomite. The pilot location was selected based on geologic considerations, reservoir quality and reservoir performance during the waterflood. A CO{sub 2} pilot was chosen, rather than full-field implementation, to investigate uncertainties associated with CO{sub 2}more » utilization rate and premature CO{sub 2} breakthrough, and overall uncertainty in the unproven CO{sub 2} flood process in the San Joaquin Valley. A summary of the design and objectives of the CO{sub 2} pilot are included along with an overview of the Lost Hills geology, discussion of pilot injection and production facilities, and discussion of new wells drilled and remedial work completed prior to commencing injection. Actual CO{sub 2} injection began on August 31, 2000 and a comprehensive pilot monitoring and surveillance program has been implemented. Since the initiation of CO{sub 2} injection, the pilot has been hampered by excessive sand production in the pilot producers due to casing damage related to subsidence and exacerbated by the injected CO{sub 2}. Therefore CO{sub 2} injection was very sporadic in 2001 and 2002 and we experienced long periods of time with no CO{sub 2} injection. As a result of the continued mechanical problems, the pilot project was terminated on January 30, 2003. This report summarizes the injection and production performance and the monitoring results through December 31, 2002 including oil geochemistry, CO{sub 2} injection tracers, crosswell electromagnetic surveys, crosswell seismic, CO{sub 2} injection profiling, cased hole resistivity, tiltmetering results, and corrosion monitoring results. Although the Lost Hills CO{sub 2} pilot was not successful, the results and lessons learned presented in this report may be applicable to evaluate and design other potential San Joaquin Valley CO{sub 2} floods.« less
Productivity and health: best practices for better measures of productivity.
Schwartz, Steven M; Riedel, John
2010-09-01
Interest in quantifying the relationship between health status and lost productivity has accelerated among employers, researchers, and benefits advisors. Our objective was to engage a dialogue to highlight important productivity measurement issues for consideration in an overall business strategy. Critical review of selected topical literature. Four functions of productivity measurement are described: 1) the purposes of a measurement initiative, 2) norms and benchmarking, 3) health and productivity cost estimators, and 4) reporting results. Each function is described in detail; challenges are noted; examples are provided. This article supports the Integrated Benefits Institute consensus statements on productivity, underscoring the need to develop a conceptual framework of productivity measurement that guides the maturation of instruments and sets forth recommendations for their application consistent with the descriptive, comparative, and evaluative functions that foster health, well-being, and work performance.

The Fourier descriptors paradigm is a well-established approach for affine-invariant characterization of shape contours. In the work presented here, we extend this method to images, and obtain a 2D Fourier representation that is invariant to image rotation. The proposed technique retains phase uniqueness, and therefore structural image information is not lost. Rotation-invariant phase coefficients were used to train a single multi-valued neuron (MVN) to recognize satellite and human face images rotated by a wide range of angles. Experiments yielded 100% and 96.43% classification rate for each data set, respectively. Recognition performance was additionally evaluated under effects of lossy JPEG compression and additive Gaussian noise. Preliminary results show that the derived rotation-invariant features combined with the MVN provide a promising scheme for efficient recognition of rotated images.

Early and accurate diagnosis of pulmonary tuberculosis (TB) is critical for successful TB control. To assist in the diagnosis of smear-negative pulmonary TB, the World Health Organisation (WHO) recommends the use of a diagnostic algorithm. Our study evaluated the implementation of the national tuberculosis programme's diagnostic algorithm in routine health care settings in Jogjakarta, Indonesia. The diagnostic algorithm is based on the WHO TB diagnostic algorithm, which had already been implemented in the health facilities. We prospectively documented the diagnostic work-up of all new tuberculosis suspects until a diagnosis was reached. We used clinical audit forms to record each step chronologically. Data on the patient's gender, age, symptoms, examinations (types, dates, and results), and final diagnosis were collected. Information was recorded for 754 TB suspects; 43.5% of whom were lost during the diagnostic work-up in health centres, 0% in lung clinics. Among the TB suspects who completed diagnostic work-ups, 51.1% and 100.0% were diagnosed without following the national TB diagnostic algorithm in health centres and lung clinics, respectively. However, the work-up in the health centres and lung clinics generally conformed to international standards for tuberculosis care (ISTC). Diagnostic delays were significantly longer in health centres compared to lung clinics. The high rate of patients lost in health centres needs to be addressed through the implementation of TB suspect tracing and better programme supervision. The national TB algorithm needs to be revised and differentiated according to the level of care.

Transportation industry workers are at high risk for exposure to traumatic incidents in the workplace. A considerable number of those exposed to such incidents will develop post-traumatic stress disorder (PTSD) symptoms, which leads to high rates of absenteeism and are costly to the public transit corporation and workplace safety compensation insurance. To determine whether the newly implemented Best Practice Intervention (BPI) provides superior outcomeswhen compared with Treatment-as-Usual (TAU) interventions in improving workers' rates of return to work (RTW), decreasing duration of time lost from work and overall reduction in severity of PTSD symptoms 6 months after exposure. A sequential mixed methods approach was used with qualitative analysis followed by a pre-post intervention design. Sixty-two participants were recruited to the (TAU) phase of the study and 79 to the (BPI) phase. Significant differences were observed between the TAU and BPI groups in number of lost work days (TAU: 20 days vs. BPI: 52 days, p = 0.02). PTSD symptoms decreased with time (MPPS score: 51.3 vs. 24.35; p < 0.001). One-fifth of the participants (21 %) did not return to work by the end of the 6 months follow-up period. The study demonstrated the value of workplace interventions in improving awareness of psychological symptoms after exposure to a traumatic incident and the value of screening for PTSD symptoms.
Performance and evaluation of small construction safety training simulations.

Back- and fall-related injuries occur frequently in construction and are costly in terms of workers' compensation claims and lost productivity. Interventions are needed that address the susceptibility to these injuries. The purpose of this study was to develop and test a safety training intervention for small construction companies (=10 employees) in Kentucky, USA. This paper will focus on the performance and evaluation of these simulation exercises, not their effectiveness in preventing injuries. The intervention consisted of six latent-image narrative simulation exercises targeted at prevention of back- or fall-related injuries, which emphasized both the economic impact of injuries and the benefits of individual and organizational prevention strategies. Participants included owner-operators, supervisors and employees. Analyses were completed to determine participant scores on the intervention along with their perceptions of the quality, realism and applicability of the training. Mean pooled performance scores (percentage correct) were 83.3% [standard deviation (SD) = 8.9, n = 143] for three back simulations and 85.2% (SD = 8.9, n = 159) for three fall-related simulations. Mean total evaluation scores (percentage of maximum) were 83.1% (SD = 11.6) and 85.5% (SD = 11.7) for the back and fall simulations, respectively. Quality and realism evaluation scores were significantly higher than scores for applicability to work. Simulations were well received as safety training exercises. Given the heterogeneous work classifications found in small construction companies, it may be preferable to target safety intervention content to specific trades rather than aim for generality across trades.

Abstract Background Working Health Service Scotland (WHSS) supports the self-employed and employees of small and medium-sized enterprises (SMEs) in Scotland with a health condition affecting their ability to work, who are either absent or at risk of becoming absent due to it. Aims To evaluate the impact on health and work outcomes of WHSS clients over a 4-year period. Methods Data were collected at enrolment, entry, discharge and follow-up at 3 and 6 months after discharge. Clients completed up to three validated health questionnaires at entry and discharge—EuroQol five dimensions (EQ-5D) and visual analogue scale (VAS); Hospital Anxiety and Depression Scale (HADS); and Canadian Occupational Performance Measure (COPM). Results A total of 13463 referrals occurred in the 4-year period; 11748 (87%) were eligible and completed entry assessment and 60% of the latter completed discharge paperwork. The majority of referrals were due to musculoskeletal conditions (84%) while 12% were referred with mental health conditions. Almost a fifth (18%) of cases were absent at entry and back at work at discharge. Work days lost while in WHSS was associated with age, length of absence prior to entering WHSS, primary health condition and time in programme. All health measures showed significant improvements from entry to discharge. Improvement in general health was sustained at 3- and 6-month follow-up. Conclusions The WHSS evaluation findings indicate that participation was associated with positive changes to health and return-to-work. The extent of the positive change in health measures and work ability can be highly important economically for employees and employers. PMID:29390161
Surface Information Loss in Comprehension
Gernsbacher, Morton Ann
2014-01-01
Shortly after a sentence has been comprehended, information about its exact surface form (e.g., its word order) becomes less available. The present research demonstrated this phenomenon during the comprehension of nonverbal stimuli (picture stories). In Experiment 1, significantly more surface (left/right orientation) information was lost after comprehending several picture stories than just one; in Experiment 2, more was lost after comprehending an entire picture story than half of one. In Experiment 3, subjects segmented the picture stories into their constituents; in Experiment 4, significantly more surface information was lost after crossing these constituents’ boundaries than before. The present research also investigated why surface information is lost. Four explanations were considered: Surface information loss is the result of performing grammatical transformations (the linguistic hypothesis), exceeding short-term memory limitations (the memory limitations hypothesis), integrating information into gist (the integration hypothesis), shifting from building one substructure to initiating another (the processing shift hypothesis). The linguistic and memory limitations hypotheses were considered inadequate; the integration and the processing shift hypotheses were tested in the last set of experiments. In Experiment 5 (using nonverbal stimuli), the predictions made by the processing shift hypothesis were confirmed; in Experiment 6 (using verbal stimuli), these results were replicated. Other implications of the processing shift hypothesis concerning surface information loss are discussed. PMID:25308975

What drives sleep-dependent memory consolidation: greater gain or less loss?
Fenn, Kimberly M; Hambrick, David Z
2013-06-01
When memory is tested after a delay, performance is typically better if the retention interval includes sleep. However, it is unclear what accounts for this well-established effect. It is possible that sleep enhances the retrieval of information, but it is also possible that sleep protects against memory loss that normally occurs during waking activity. We developed a new research approach to investigate these possibilities. Participants learned a list of paired-associate items and were tested on the items after a 12-h interval that included waking or sleep. We analyzed the number of items gained versus the number of items lost across time. The sleep condition showed more items gained and fewer items lost than did the wake condition. Furthermore, the difference between the conditions (favoring sleep) in lost items was greater than the difference in gain, suggesting that loss prevention may primarily account for the effect of sleep on declarative memory consolidation. This finding may serve as an empirical constraint on theories of memory consolidation.
Disability pension from back pain among social security beneficiaries, Brazil.
Meziat Filho, Ney; Silva, Gulnar Azevedo E
2011-06-01
To describe disability pension from back pain. Descriptive study based on data from the Brazilian Social Security Beneficiary Database and the Social Security Statistics Annual Report in 2007. The incidence rate of disability pension from back pain was estimated according to gender and age by Brazilian states. There were also estimated working days lost due to back pain disability by occupation. Idiopathic back pain was the most common cause of disability among social security pension and accidental retirement. Most pensioners were living in urban areas and were commercial workers. The rate of disability pension from back pain in Brazil was 29.96 per 100,000 beneficiaries. A higher rate was seen among males and older individuals. Rondônia showed the highest rate, four times as high as expected (RR= 4.05) followed by Bahia with a rate about twice as high as expected (RR=2.07). Commercial workers accounted for 96.9% of working days lost due to disability. Back pain was a major cause of disability in 2007 mostly among commercial workers showing great differences between the Brazilian states.

The high costs and logistics limitations of ship-based data collection represent an obstacle for a persistent in-situ data collection. Satellite-operated Autonomous Underwater Vehicles (AUV's) or gliders (as these AUV's are generally known by the scientific community) are presented as an inexpensive and reliable alternative to perform long-term and real-time ocean monitoring of important parameters such as temperature, salinity, water-quality and acoustics. This work is focused on the performance statistics and the reliability for continuous operation of a fleet of seven gliders navigating in Santos Basin - Brazil, since March 2013. The gliders performance were evaluated by the number of standby days versus the number of operating days, the number of interrupted missions due to (1) equipment failure, (2) weather, (3) accident versus the number of successful missions and the amount and quality of data collected. From the start of the operations in March 2013 to the preparation of this work (July 2015), a total of 16 glider missions were accomplished, operating during 728 of the 729 days passed since then. From this total, 11 missions were successful, 3 missions were interrupted due to equipment failure and 2 gliders were lost. Most of the identified issues were observed in the communication with the glider (when recovery was necessary) or the optode sensors (when remote settings solved the problem). The average duration of a successful mission was 103 days while interrupted ones ended on average in 7 days. The longest mission lasted for 139 days, performing 859 continuous profiles and covering a distance of 2734 Km. The 2 projects performed together 6856 dives, providing an average of 9,5 profiles per day or one profile every 2,5 hours each day during 2 consecutive years.

Fatal fall into a volcanic fumarole.
Cantrell, Lee; Young, Michael
2009-01-01
Fatalities secondary to inhalation of volcanic gases in the United States have rarely been reported. We report the deaths of 3 ski patrol members at a popular California ski resort. After a snowstorm, ski patrol members were fencing off a well-known volcanic fumarole when the snow around the vent collapsed. Two members slid into the deep hole and rapidly lost consciousness. A third member carrying oxygen descended into the hole and also lost consciousness. A fourth member affixed an oxygen mask, but still lost consciousness upon descent. The 3 initial victims expired at the scene, while the fourth victim survived. Autopsy results for all 3 were consistent with a suffocation/asphyxiation death. In the case described, the involved fumarole is a well-known source of toxic gases. Atmospheric sampling data dating back decades demonstrate that carbon dioxide levels typically range from 97% to 99%, nitrogen gas from 1% to 3%, and hydrogen sulfide from .004% to .07%. Other gases in smaller concentrations include oxygen, hydrogen, and carbon monoxide. Given the rapidity with which our victims lost consciousness and the historical data available on the Mammoth Mountain Fumarole (MMF), it is plausible that our patients suffered from acute asphyxiation, although the contribution of the directly toxic effects of the gases involved cannot be ruled out. During winter months, snow can build up and disguise volcanic vents and potentially trap toxic fumes to form dangerous, gas-filled pits. Recognition of such potential hazards is essential when working in or venturing into volcanically active areas during the winter.

The performance and competitiveness of manufacturing companies is dependent on the availability, reliability and productivity of their production facilities. Low productivity, downtime, and poor machine performance is often linked to inadequate plant maintenance, which in turn can lead to reduced production levels, increasing costs, lost market opportunities, and lower profits. These pressures have given firms worldwide the motivation to explore and embrace proactive maintenance strategies over the traditional reactive firefighting methods. The traditional view of maintenance has shifted into one of an overall view that encompasses Overall Equipment Efficiency, Stakeholders Management and Life Cycle assessment. From practical point of view it requires changes in approach to maintenance represented by managers and changes in actions performed within maintenance area. Managers have to understand that maintenance is not only about repairs and conservations of machines and devices, but also actions striving for more efficient resources management and care for safety and health of employees. The purpose of the work is to present strategic analysis based on SWOT analysis to identify the opportunities and strengths of maintenance process, to benefit from them as much as possible, as well as to identify weaknesses and threats, so that they could be eliminated or minimized.

During normal operations, public safety personnel may become injured, leading them to seek medical care and possible time off. Examining the nature and patterns of injury may help to identify preventive health measures for all public safety personnel and address specific needs of each discipline based on actual risk. Objective. To determine the types and severity of injuries encountered by public safety personnel during routine work conditions within a single urban population. De-identified workers' compensation data for emergency medical services (EMS), fire, and police providers from one urban center between January 1, 2005, and May 31, 2007, were examined. Data included type of injury, severity of injury, and date of event. Severity was categorized as follows: lost time (type 1), medical evaluation (type 2), report only (type 3), restricted duty (type 4), and not reported (type 5). Analysis of variance (ANOVA) and a pairwise t-test between groups with a Bonferroni correction was performed to determine the relative risk of injuries between groups. During the 29-month interval, an average workforce of 850 firefighters, 194 EMS providers, and 850 police officers were employed. A total of 1,295 workers' compensation events were documented, with 243 (18%) reported from EMS, 477 (36%) from fire, and 608 (46%) from police. Type 1 injuries were more common in fire (39%) and police (38%) than EMS (23%). EMS had higher rates of lost work (type 1) and medical evaluations (type 2) than both fire and police. Workers' compensation events common to all bureaus were minor trauma (76%) and exposures to blood-borne pathogens (12%). Minor traumatic injuries, mostly associated with axial musculoskeletal strains and extremity injuries, were responsible for the majority of injuries resulting in missed work. Injuries more common in a specific bureau included motor vehicle crashes and gunshot wounds (police) and cardiovascular disease, burns, and heat illness (fire). Public safety personnel are affected by both profession-specific and non-profession-specific injuries. Overall, EMS has higher rates of missed time and medical evaluations than both fire and police. These data highlight the need to make direct comparisons of various public safety personnel bureaus using a common time interval and locale in order to rationally plan interventions and apply resources.
Evaluating the precision of passive sampling methods using ...
To assess these models, four different thicknesses of low-density polyethylene (LDPE) passive samplers were co-deployed for 28 days in the water column at three sites in New Bedford Harbor, MA, USA. Each sampler was pre-loaded with six PCB performance reference compounds (PRCs) to assess equilibrium status, such that the percent of PRC lost would range depending on PRC and LDPE thickness. These data allow subsequent Cfree comparisons to be made in two ways: (1) comparing Cfree derived from one thickness using different models and (2) comparing Cfree derived from the same model using different thicknesses of LDPE. Following the deployments, the percent of PRC lost ranged from 0-100%. As expected, fractional equilibrium decreased with increasing PRC molecular weight as well as sampler thickness. Overall, a total of 27 PCBs (log KOW ranging from 5.07 – 8.09) were measured at Cfree concentrations varying from 0.05 pg/L (PCB 206) to about 200 ng/L (PCB 28) on a single LDPE sampler. Relative standard deviations (RSDs) for total PCB measurements using the same thickness and varying model types range from 0.04-12% and increased with sampler thickness. Total PCB RSD for measurements using the same model and varying thickness ranged from: 6 – 30%. No RSD trends between models were observed but RSD did increase as Cfree decreased. These findings indicate that existing models yield precise and reproducible results when using LDPE and PRCs to measure Cfree. This work in
“A System for Automatically Maintaining Pressure in a Commercial Truck Tire”
DOE Office of Scientific and Technical Information (OSTI.GOV)
Maloney, John
2017-07-07
Under-inflated tires significantly reduce a vehicle’s fuel efficiency by increasing rolling resistance (drag force). The Air Maintenance Technology (“AMT”) system developed through this project replenishes lost air and maintains optimal tire cavity pressure whenever the tire is rolling in service, thus improving overall fuel economy by reducing the tire’s rolling resistance. The system consists of an inlet air filter, an air pump driven by tire deformation during rotation, and a pressure regulating device. Pressurized air in the tire cavity naturally escapes by diffusion through the tire and wheel, leaks in tire seating, and through the filler valve and its seating.more » As a result, tires require constant maintenance to replenish lost air. Since manual tire inflation maintenance is both labor intensive and time consuming, it is frequently overlooked or ignored. By automating the maintenance of optimal tire pressure, the tire’s contribution to the vehicle’s overall fuel economy can be maximized. The work was divided into three phases. The objectives of Phase 1, Planning and Initial Design, resulted in an effective project plan and to create a baseline design. The objectives for Phase 2, Design and Process Optimization, were: to identify finalized design for the pump, regulator and filter components; identify a process to build prototype tires; assemble prototype tires; test prototype tires and document results. The objectives of Phase 3, Design Release and Industrialization, were to finalize system tire assembly, perform release testing and industrialize the assembly process.« less

Purpose : to assess the loss in hematocrit and hemoglobin, if any, 24 hours after hip arthroscopy. Methods : thirty-five patients were included. Laboratory tests including complete blood count and white blood cells were performed one week prior to surgery and 24 hours after. Surgical time, volume of saline perfusion and pump perfusion was also recorded. Results : mean preoperative hematocrit was 42.01% (4.63 SD), whereas mean postoperative hematocrit at 24 h decreased to 36.78% (SD 5.11) (p <0.021.). Mean preoperative hemoglobin was 14.23 g/dL (1.73 SD), and mean postoperative hemoglobin at 24 h decreased to 12.40 g/dL (SD 1.92) (p =0.03.). Platelets and white blood cells, as well as the remaining biochemical parameters showed no significant difference between preoperative and postoperative samples. Lost blood volume worked out with the logarithmic method for estimated blood loss was which 0.78 liters (SD 0.45). Lost blood volume taking into account, the red blood cell mass was also 0.78 liters (SD 0.45). Conclusion : a significant decrease in hemoglobin and hematocrit after hip arthroscopy was observed. Although patients did not show clinical signs of anemia or bleeding, blood loss should be considered when planning a hip arthroscopy, especially in patients at risk of anemia. According to our results, we recommend a postoperative control analysis at 24 h. Level of Evidence : level II, Diagnostic Study. PMID:26401169

The Internet is a powerful tool that has changed the way people work. However, the ubiquity of the Internet has led to a new workplace threat to productivity-cyberloafing. Building on the ego depletion model of self-regulation, we examine how lost and low-quality sleep influence employee cyberloafing behaviors and how individual differences in conscientiousness moderate these effects. We also demonstrate that the shift to Daylight Saving Time (DST) results in a dramatic increase in cyberloafing behavior at the national level. We first tested the DST-cyberloafing relation through a national quasi-experiment, then directly tested the relation between sleep and cyberloafing in a closely controlled laboratory setting. We discuss the implications of our findings for theory, practice, and future research.

The objective of this study was to estimate the annual direct and indirect costs associated with Dravet Syndrome (DS). A survey was electronically administered to the caregivers of patients with DS treated at Children's Hospital Colorado. Survey domains included healthcare utilization of the patient with DS and DS caregiver work productivity and activity impairment. Patient healthcare utilization was measured using modified questions from the National Health Interview Survey; caregiver work productivity and activity impairment were measured using modified questions from the Work Productivity and Activity Impairment questionnaire. Direct costs were calculated by multiplying the caregiver-reported healthcare utilization rates by the mean unit cost for each healthcare utilization category. Indirect costs included lost productivity, income loss, and lost leisure time. The indirect costs were a function of caregiver-reported hours spent caregiving and an hourly unit cost. The survey was emailed to 60 DS caregivers, of which 34 (57% response rate) responded. Direct costs on average were $27,276 (95% interval: $15,757, $41,904) per patient with DS. Hospitalizations ($11,565 a year) and in-home medical care visits ($9894 a year) were substantial cost drivers. Additionally, caregivers reported extensive time spent providing care to an individual with DS. This caregiver time resulted in average annual indirect costs of $81,582 (95% interval: $57,253, $110,151), resulting in an average total annual financial burden of $106,378 (95% interval: $78,894, $137,906). Dravet Syndrome results in substantial healthcare utilization, financial burden, and time commitment. Establishing evidence on the financial burden of DS is essential to understanding the overall impact of DS, identifying potential areas for support needs, and assessing the impact of novel treatments as they become available. Based on the study findings, in-home visits, hospitalizations, and lost productivity and leisure time of caregivers are key domains for DS economic evaluations. Future research should extend these estimates to include the potential additional healthcare utilization of the DS caregiver. Copyright © 2018 Elsevier Inc. All rights reserved.

Purpose The objective of this systematic review was to synthesize evidence on the effectiveness of workplace-based return-to-work (RTW) interventions and work disability management (DM) interventions that assist workers with musculoskeletal (MSK) and pain-related conditions and mental health (MH) conditions with RTW. Methods We followed a systematic review process developed by the Institute for Work & Health and an adapted best evidence synthesis that ranked evidence as strong, moderate, limited, or insufficient. Results Seven electronic databases were searched from January 1990 until April 2015, yielding 8898 non-duplicate references. Evidence from 36 medium and high quality studies were synthesized on 12 different intervention categories across three broad domains: health-focused, service coordination, and work modification interventions. There was strong evidence that duration away from work from both MSK or pain-related conditions and MH conditions were significantly reduced by multi-domain interventions encompassing at least two of the three domains. There was moderate evidence that these multi-domain interventions had a positive impact on cost outcomes. There was strong evidence that cognitive behavioural therapy interventions that do not also include workplace modifications or service coordination components are not effective in helping workers with MH conditions in RTW. Evidence for the effectiveness of other single-domain interventions was mixed, with some studies reporting positive effects and others reporting no effects on lost time and work functioning. Conclusions While there is substantial research literature focused on RTW, there are only a small number of quality workplace-based RTW intervention studies that involve workers with MSK or pain-related conditions and MH conditions. We recommend implementing multi-domain interventions (i.e. with healthcare provision, service coordination, and work accommodation components) to help reduce lost time for MSK or pain-related conditions and MH conditions. Practitioners should also consider implementing these programs to help improve work functioning and reduce costs associated with work disability.
Do Dynamic Fat and Fat-Free Mass Changes follow Theoretical Driven Rules in Athletes?
Silva, Analiza M; Matias, Catarina N; Santos, Diana A; Rocha, Paulo M; Minderico, Cláudia S; Thomas, Diana; Heymsfield, Steven B; Sardinha, Luís B

Maximizing fat mass (FM) loss while preserving or increasing fat-free mass (FFM) is a central goal for athletic performance but the composition of body weight (BW) changes over time with training are largely unknown. We aimed to analyze FM and FFM contributions to BW changes and to test if these contributions follow established rules and predictions over one athletic season. Seventy athletes (42 men; handball, volleyball, basketball, triathlon, and swimming) were evaluated from the beginning to the competitive stage of the season and were empirically divided into those who lost (n = 20) or gained >1.5% BW (n = 50). FM and FFM were evaluated with a four-compartment model. Energy densities (ED) of 1.0 kcal·g for FFM and 9.5 kcal·g for FM were used to calculate ED/per kilogram BW change. Athletes that lost >1.5% BW decreased FM by 1.7 ± 1.6 kg (P < 0.05), whereas FFM loss was nonsignificant (-0.7 ± 2.1 kg). Those who gained >1.5% BW increased FFM by 2.3 ± 2.1 kg (P < 0.05) with nonsignificant FM gains (0.4 ± 2.2 kg). The proportion of BW change as FM for those who lost or gained BW was 90% (ED: 8678 ± 2147 kcal·kg) and 5% (ED: 1449 ± 1525 kcal·kg), respectively (P < 0.001). FFM changes from Forbes Curve were inversely related to observed changes (r = -0.64; r = -0.81, respectively for those who lost or gained BW). Athletes that lost BW used 90% of the energy from FM while in those gaining BW, 95% was directed to FFM. When BW is lost, dynamic changes in its composition do not follow established rules and predictions used for lean or overweight/obese nonathletic populations.
Record of archaeal activity at the serpentinite-hosted Lost City Hydrothermal Field.

Samples of young, outer surfaces of brucite-carbonate deposits from the ultramafic-hosted Lost City hydrothermal field were analyzed for DNA and lipid biomarker distributions and for carbon and hydrogen stable isotope compositions of the lipids. Methane-cycling archaeal communities, notably the Lost City Methanosarcinales (LCMS) phylotype, are specifically addressed. Lost City is unlike all other hydrothermal systems known to date and is characterized by metal- and CO2 -poor, high pH fluids with high H2 and CH4 contents resulting from serpentinization processes at depth. The archaeal fraction of the microbial community varies widely within the Lost City chimneys, from 1-81% and covaries with concentrations of hydrogen within the fluids. Archaeal lipids include isoprenoid glycerol di- and tetraethers and C25 and C30 isoprenoid hydrocarbons (pentamethylicosane derivatives - PMIs - and squalenoids). In particular, unsaturated PMIs and squalenoids, attributed to the LCMS archaea, were identified for the first time in the carbonate deposits at Lost City and probably record processes exclusively occurring at the surface of the chimneys. The carbon isotope compositions of PMIs and squalenoids are remarkably heterogeneous across samples and show highly (13) C-enriched signatures reaching δ(13) C values of up to +24.6‰. Unlike other environments in which similar structural and isotopic lipid heterogeneity has been observed and attributed to diversity in the archaeal assemblage, the lipids here appear to be synthesized solely by the LCMS. Some of the variations in lipid isotope signatures may, in part, be due to unusual isotopic fractionation during biosynthesis under extreme conditions. However, we argue that the diversity in archaeal abundances, lipid structure and carbon isotope composition rather reflects the ability of the LCMS archaeal biofilms to adapt to chemical gradients in the hydrothermal chimneys and possibly to perform either methanotrophy or methanogenesis using dissolved inorganic carbon, methane or formate as a function of the prevailing environmental conditions. © 2013 John Wiley & Sons Ltd.

Natural physique competitions are based on subjective judgments of how a competitor appears on show day. Prior to competition, there is a prolonged dieting phase referred to as contest preparation. The primary goal is to reduce body fat levels while maintaining skeletal muscle mass. The study tracked the physiological and psychological changes for a 24 year old female preparing for a physique competition. Purpose: The study was conducted to describe the physiological and psychological changes of a female physique competitor who engages in long-term contest preparation. Methods: Diet, body composition, blood work, energy expenditure, mood, and performance were evaluated through contest preparation. Results: The participant lost 10.1kg throughout contest preparation in a strong weekly linear pattern (R2=0.97). Body fat was reduced from 30.45% to 15.85% while fat free mass was maintained. Mood for the participant remained stable until month five, when an observed variation occurred, with performance maintaining. Conclusions: Contest preparation was successful in reducing the body fat in the participant while having a minimum effect on both performance and fat free mass. For athletes looking to lose large amounts of body fat with minimal performance decrements a prolonged diet period with moderate exercise and food restriction can be an effective solution.

Effect of retransmission and retrodiction on estimation and fusion in long-haul sensor networks
Liu, Qiang; Wang, Xin; Rao, Nageswara S. V.; ...
2016-01-01
In a long-haul sensor network, sensors are remotely deployed over a large geographical area to perform certain tasks, such as target tracking. In this work, we study the scenario where sensors take measurements of one or more dynamic targets and send state estimates of the targets to a fusion center via satellite links. The severe loss and delay inherent over the satellite channels reduce the number of estimates successfully arriving at the fusion center, thereby limiting the potential fusion gain and resulting in suboptimal accuracy performance of the fused estimates. In addition, the errors in target-sensor data association can alsomore » degrade the estimation performance. To mitigate the effect of imperfect communications on state estimation and fusion, we consider retransmission and retrodiction. The system adopts certain retransmission-based transport protocols so that lost messages can be recovered over time. Besides, retrodiction/smoothing techniques are applied so that the chances of incurring excess delay due to retransmission are greatly reduced. We analyze the extent to which retransmission and retrodiction can improve the performance of delay-sensitive target tracking tasks under variable communication loss and delay conditions. Lastly, simulation results of a ballistic target tracking application are shown in the end to demonstrate the validity of our analysis.« less

The problem of sick absences from work is correlated to a series of organizational, social and psychological factors which interact with risk factors typical of the work performed, and thus determine how frequently absences occur. The correlation between morbidity and work is of interest in itself for studying the processes of occupational mobility. To examine, using data from administrative sources, the association of sick absence with individual and workplace factors, as well as the relationship between illness and career mobility. Employee sick absence data registered at INPS (National Institute of Social Insurance) in the period 1992-95 were studied using a sample of 124,686 subjects. The probability of being absent from work due to illness did not appear to be affected by sex or age. The sectors more at risk for sick absences were the service sector, business and commerce. Inequalities were noted in illness rates to the disadvantage of those who had received redundancy payments in the previous years. New hirings and upward mobility were associated with a lower occurrence of illness. A higher probability of illness was observed in those who had lost their jobs and in those who had changed from full-time to part-time work. It is likely that formal regulations and practices in use within INPS vary according to the different economic activities. Therefore this source allows investigation of illness only in activities with homogeneous regulatory aspects. The results confirm a link between unstable work situations and illness and between illness and career advancement.

This phase 3 study evaluated quality of life, functioning, and productivity after treatment with extended-release (ER) hydrocodone formulated with CIMA ® Abuse-Deterrence Technology platform. Patients with chronic pain were rolled over from a 12-week placebo-controlled hydrocodone ER study or were newly enrolled. Hydrocodone ER doses were titrated (15 to 90 mg every 12 hours) to an analgesic dose, and patients received up to 52 weeks of open-label treatment. Assessments included Clinician Assessment of Patient Function (CAPF), Patient Assessment of Function (PAF), Brief Pain Inventory-Short Form (BPI-SF), 36-item Short-Form Health Survey (SF-36), Sheehan Disability Scale (SDS), and World Health Organization Health and Work Performance Questionnaire-Short Form (HPQ-SF). Of 330 enrolled patients, 291 composed the full analysis population. By week 4, ≥ 50% of patients showed improvement from baseline in all 5 CAPF domains (general activities, walking, work/daily living, relationships, and enjoyment of life) and 6 of 7 PAF domains (work attendance, work performance, walking, exercise, socializing, and enjoying life). Mean decreases from baseline of 2 to 3 points were noted for BPI-SF pain interference questions from week 4 through endpoint. Mean improvements from baseline to endpoint in SF-36 subscales ranged from 3.3 to 22.3, and SDS scores improved from moderate (4.8 to 5.1) to mild (2.5 to 2.8) disruptions in work/school, social life, and family life. At endpoint, mean HPQ-SF absolute absenteeism scores decreased from 13.6 to 10.0 hours lost/month and absolute presenteeism scores improved from 67.0 to 77.1. Patients receiving hydrocodone ER showed early numeric improvements in functioning that continued throughout this 12-month study. © 2016 World Institute of Pain.

Coupling neutronics/thermal-hydraulics calculations for the design of nuclear reactors are a growing trend in the scientific community. This approach allows to properly represent the mutual feedbacks between the neutronic distribution and the thermal-hydraulics properties of the materials composing the reactor, details which are often lost when separate analysis are performed. In this work, a test case for a generation IV sodium-cooled fast reactor (SFR), based on the ASTRID concept developed by CEA, is proposed. Two sub-assemblies (SA) characterized by different fuel enrichment and layout are considered. Specifications for the test case are provided including geometrical data, material compositions, thermo-physical properties and coupling scheme details. Serpent and ANSYS-CFX are used as reference in the description of suitable inputs for the performing of the benchmark, but the use of other code combinations for the purpose of validation of the results is encouraged. The expected outcome of the test case are the axial distribution of volumetric power generation term (q‴), density and temperature for the fuel, the cladding and the coolant.

The purpose of this work is the development and characterisation of new hybrid polysaccharide (FucoPol) membranes. These membranes were prepared by incorporation of a SiO 2 network homogeneously dispersed by using a sol-gel method with GPTMS as a crosslinker silica precursor. They were further crosslinked with CaCl 2 for reinforcement of mechanical properties and improvement of their permeation performance. They were characterised in terms of their structural, mechanical and thermal properties. They presented a dense and homogeneous structure, resistant to deformation, with a Tg of 43 °C and a thermal decomposition between 240 and 251 °C. The hybrid FucoPol membranes were tested for ethanol dehydration by pervaporation and also for nitrogen dehydration. They exhibited high water selectivity values, similar to PERVAP ® 4101, however they lost their stability when exposed to solutions of 10.0 wt.% water in ethanol. In contrast, these membranes were stable when applied in N 2 dehydration, leading to reproducible performance and very high water selectivities. Copyright © 2018 Elsevier Ltd. All rights reserved.
Eigenvalue sensitivity of sampled time systems operating in closed loop
NASA Astrophysics Data System (ADS)
Bernal, Dionisio
2018-05-01
The use of feedback to create closed-loop eigenstructures with high sensitivity has received some attention in the Structural Health Monitoring field. Although practical implementation is necessarily digital, and thus in sampled time, work thus far has center on the continuous time framework, both in design and in checking performance. It is shown in this paper that the performance in discrete time, at typical sampling rates, can differ notably from that anticipated in the continuous time formulation and that discrepancies can be particularly large on the real part of the eigenvalue sensitivities; a consequence being important error on the (linear estimate) of the level of damage at which closed-loop stability is lost. As one anticipates, explicit consideration of the sampling rate poses no special difficulties in the closed-loop eigenstructure design and the relevant expressions are developed in the paper, including a formula for the efficient evaluation of the derivative of the matrix exponential based on the theory of complex perturbations. The paper presents an easily reproduced numerical example showing the level of error that can result when the discrete time implementation of the controller is not considered.

Due to their high specific surface area and good electric conductivity, nitrogen-doped porous carbons (NPCs) and carbon nanotubes (CNTs) have attracted much attention for electrochemical energy storage applications. In the present work, we firstly prepared MWCNT/ZIF-8 composites by decoration of zeolitic imidazolate frameworks (ZIF-8) onto the surface of multi-walled CNTs (MWCNTs), then obtained MWCNT/NPCs by the direct carbonization of MWCNT/ZIF-8. By controlling the reaction conditions, MWCNT/ZIF-8 with three different particle sizes were synthesized. The effect of NPCs size on capacitance performance has been evaluated in detail. The MWCNT/NPC with large-sized NPC (MWCNT/NPC-L) displayed the highest specific capacitance of 293.4 F g -1 at the scan rate of 5 mV s -1 and only lost 4.2% of capacitance after 10 000 cyclic voltammetry cycles, which was attributed to the hierarchically structured pores, N-doping and high electrical conductivity. The studies of symmetric two-electrode supercapacitor cells also confirmed MWCNT/NPC-L as efficient electrode materials that have good electrochemical performance, especially for high-rate applications.
Diagnostic work-up and loss of tuberculosis suspects in Jogjakarta, Indonesia
2012-01-01
Background Early and accurate diagnosis of pulmonary tuberculosis (TB) is critical for successful TB control. To assist in the diagnosis of smear-negative pulmonary TB, the World Health Organisation (WHO) recommends the use of a diagnostic algorithm. Our study evaluated the implementation of the national tuberculosis programme's diagnostic algorithm in routine health care settings in Jogjakarta, Indonesia. The diagnostic algorithm is based on the WHO TB diagnostic algorithm, which had already been implemented in the health facilities. Methods We prospectively documented the diagnostic work-up of all new tuberculosis suspects until a diagnosis was reached. We used clinical audit forms to record each step chronologically. Data on the patient's gender, age, symptoms, examinations (types, dates, and results), and final diagnosis were collected. Results Information was recorded for 754 TB suspects; 43.5% of whom were lost during the diagnostic work-up in health centres, 0% in lung clinics. Among the TB suspects who completed diagnostic work-ups, 51.1% and 100.0% were diagnosed without following the national TB diagnostic algorithm in health centres and lung clinics, respectively. However, the work-up in the health centres and lung clinics generally conformed to international standards for tuberculosis care (ISTC). Diagnostic delays were significantly longer in health centres compared to lung clinics. Conclusions The high rate of patients lost in health centres needs to be addressed through the implementation of TB suspect tracing and better programme supervision. The national TB algorithm needs to be revised and differentiated according to the level of care. PMID:22333111

Scientists and engineers constantly face new challenges, despite myriad advances in computing. More sets of data are collected today from earth and sky than there is time or resources available to carefully analyze them. Some problems either don't have fast algorithms to solve them or have solutions that must be found among millions of options, a situation akin to finding a needle in a haystack. But all hope is not lost: advances in technology and the Internet have empowered the general public to participate in the scientific process via individual computational resources and brain cognition, which isn't matched by any machine. Citizen scientists are volunteers who perform scientific work by making observations, collecting and disseminating data, making measurements, and analyzing or interpreting data without necessarily having any scientific training. In so doing, individuals from all over the world can contribute to science in ways that wouldn't have been otherwise possible.

A reel of black & white film shot nearly 60 years ago has surfaced at Berkeley Lab, depicting the discovery of Mendelevium - or Element 101 - as reenacted by some of the legendary scientists who did the actual work at that time. Since the 1940s, Berkeley Lab scientists were locked in a race to synthesize new elements, and more often than not, they came out winners. Sixteen elements, most of them in the actinide series at the bottom of the periodic table, were discovered and synthesized by its researchers. Retired Berkeley Lab physicist Claude Lyneis found the reel inmore » a box of dusty and deteriorating films slated for disposal. Using digital editing skills he acquired to make videos of his son's lacrosse team, Lyneis has produced and narrated an excerpt of this nearly-lost footage.

A reel of black & white film shot nearly 60 years ago has surfaced at Berkeley Lab, depicting the discovery of Mendelevium - or Element 101 - as reenacted by some of the legendary scientists who did the actual work at that time. Since the 1940s, Berkeley Lab scientists were locked in a race to synthesize new elements, and more often than not, they came out winners. Sixteen elements, most of them in the actinide series at the bottom of the periodic table, were discovered and synthesized by its researchers. Retired Berkeley Lab physicist Claude Lyneis found the reel in a box of dusty and deteriorating films slated for disposal. Using digital editing skills he acquired to make videos of his son's lacrosse team, Lyneis has produced and narrated an excerpt of this nearly-lost footage. It is an entertaining and informative look at the pioneering physics performed at UC Berkeley and Lawrence Berkeley National Laboratory's hillside campus.
SOUNET: Self-Organized Underwater Wireless Sensor Network.
Kim, Hee-Won; Cho, Ho-Shin
2017-02-02
In this paper, we propose an underwater wireless sensor network (UWSN) named SOUNET where sensor nodes form and maintain a tree-topological network for data gathering in a self-organized manner. After network topology discovery via packet flooding, the sensor nodes consistently update their parent node to ensure the best connectivity by referring to the timevarying neighbor tables. Such a persistent and self-adaptive method leads to high network connectivity without any centralized control, even when sensor nodes are added or unexpectedly lost. Furthermore, malfunctions that frequently happen in self-organized networks such as node isolation and closed loop are resolved in a simple way. Simulation results show that SOUNET outperforms other conventional schemes in terms of network connectivity, packet delivery ratio (PDR), and energy consumption throughout the network. In addition, we performed an experiment at the Gyeongcheon Lake in Korea using commercial underwater modems to verify that SOUNET works well in a real environment.

Visual working memory (VWM) has a limited capacity. This limitation can be mitigated by the use of focused attention: if attention is drawn to the relevant working memory content before test, performance improves (the so-called retro-cue benefit). This study tests 2 explanations of the retro-cue benefit: (a) Focused attention protects memory representations from interference by visual input at test, and (b) focusing attention enhances retrieval. Across 6 experiments using color recognition and color reproduction tasks, we varied the amount of color interference at test, and the delay between a retrieval cue (i.e., the retro-cue) and the memory test. Retro-cue benefits were larger when the memory test introduced interfering visual stimuli, showing that the retro-cue effect is in part because of protection from visual interference. However, when visual interference was held constant, retro-cue benefits were still obtained whenever the retro-cue enabled retrieval of an object from VWM but delayed response selection. Our results show that accessible information in VWM might be lost in the processes of testing memory because of visual interference and incomplete retrieval. This is not an inevitable state of affairs, though: Focused attention can be used to get the most out of VWM. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

There are few data on excess direct and indirect costs of diabetes in India and limited data on rural costs of diabetes. We aimed to further explore these aspects of diabetes burdens using a clinic-based, comparative cost-of-illness study. Persons with diabetes ( n = 606) were recruited from government, private, and rural clinics and compared to persons without diabetes matched for age, sex, and socioeconomic status ( n = 356). We used interviewer-administered questionnaires to estimate direct costs (outpatient, inpatient, medication, laboratory, and procedures) and indirect costs [absence from (absenteeism) or low productivity at (presenteeism) work]. Excess costs were calculated as the difference between costs reported by persons with and without diabetes and compared across settings. Regression analyses were used to separately identify factors associated with total direct and indirect costs. Annual excess direct costs were highest amongst private clinic attendees (INR 19 552, US$425) and lowest amongst government clinic attendees (INR 1204, US$26.17). Private clinic attendees had the lowest excess absenteeism (2.36 work days/year) and highest presenteeism (0.06 work days/year) due to diabetes. Government clinic attendees reported the highest absenteeism (7.48 work days/year) and lowest presenteeism (-0.31 work days/year). Ten additional years of diabetes duration was associated with 11% higher direct costs ( p < 0.001). Older age ( p = 0.02) and longer duration of diabetes ( p < 0.001) were associated with higher total lost work days. Excess health expenditures and lost productivity amongst individuals with diabetes are substantial and different across care settings. Innovative solutions are needed to cope with diabetes and its associated cost burdens in India.

2013-01-01
Welcome to the 2013 edition of the NASA Range Safety Annual Report. Funded by NASA Headquarters, this report provides an Agency overview for current and potential range users. This report contains articles which cover a variety of subject areas, summaries of various activities performed during the past year, links to past reports, and information on several projects that may have a profound impact on the way business will be conducted in the future. Specific topics discussed in the 2013 NASA Range Safety Annual Report include a program overview and 2013 highlights, Range Safety Training, Independent Assessments, support to Program Operations at all ranges conducting NASA launch/flight operations, a continuing overview of emerging range safety-related technologies, and status reports from all of the NASA Centers that have Range Safety responsibilities. Every effort has been made to include the most current information available. We recommend this report be used only for guidance and that the validity and accuracy of all articles be verified for updates. As is the case each year, we had a wide variety of contributors to this report from across our NASA Centers and the national range safety community at large, and I wish to thank them all. On a sad note, we lost one of our close colleagues, Dr. Jim Simpson, due to his sudden passing in December. His work advancing the envelope of autonomous flight safety systems software/hardware development leaves a lasting impression on our community. Such systems are being flight tested today and may one day be considered routine in the range safety business. The NASA family has lost a pioneer in our field, and he will surely be missed. In conclusion, it has been a very busy and productive year, and I look forward to working with all of you in NASA Centers/Programs/Projects and with the national Range Safety community in making Flight/Space activities as safe as they can be in the upcoming year.

Obesity and workers' compensation: results from the Duke Health and Safety Surveillance System.
Ostbye, Truls; Dement, John M; Krause, Katrina M

Obese individuals have increased morbidity and use of health services. Less is known about the effect of obesity on workers' compensation. The objective of this study was to determine the relationship between body mass index (BMI) (calculated as weight in kilograms divided by height in meters squared) and number and types of workers' compensation claims, associated costs, and lost workdays. Retrospective cohort study. Participants included 11 728 health care and university employees (34 858 full-time equivalents [FTEs]) with at least 1 health risk appraisal between January 1, 1997, and December 31, 2004. The main outcome measures were stratified rates of workers' compensation claims, associated costs, and lost workdays, calculated by BMI, sex, age, race/ethnicity, smoking status, employment duration, and occupational group. The body part affected, nature of the illness or injury, and cause of the illness or injury were also investigated. Multivariate Poisson regression models examined the effects of BMI, controlling for demographic and work-related variables. There was a clear linear relationship between BMI and rate of claims. Employees in obesity class III (BMI >/=40) had 11.65 claims per 100 FTEs, while recommended-weight employees had 5.80; the effect on lost workdays (183.63 vs 14.19 lost workdays per 100 FTEs), medical claims costs ($51 091 vs $7503 per 100 FTEs), and indemnity claims costs ($59 178 vs $5396 per 100 FTEs) was even stronger. The claims most strongly affected by BMI were related to the following: lower extremity, wrist or hand, and back (body part affected); pain or inflammation, sprain or strain, and contusion or bruise (nature of the illness or injury); and falls or slips, lifting, and exertion (cause of the illness or injury). The combination of obesity and high-risk occupation was particularly detrimental. Maintaining healthy weight not only is important to workers but should also be a high priority for their employers given the strong effect of BMI on workers' injuries. Complementing general interventions to make all workplaces safer, work-based programs targeting healthy eating and physical activity should be developed and evaluated.

Renewable energy technologies based on solar energy concentration are important alternatives to supply the rising energy demand in the world and to mitigate the negative environmental impact caused by the extensive use of fossil-fuels. In this work, a thermodynamic model based on energy and exergy analyses is developed to study the transient behavior of a Concentrated Solar Power (CSP) supercritical CO2 plant operating under different seasonal conditions. The system analyzed is composed of a central receiver, hot and cold thermal energy storage units, a heat exchanger, a recuperator, and three-stage compression and expansion subsystems with intercoolers between compressors and reheatersmore » between turbines, respectively. From the exergy analysis, the recuperator, the hot thermal energy storage, and the solar receiver were identified as the main sources for exergy destruction with more than 70% of the total lost work in the plant. These components offer an important potential to improve the system’s performance via design optimization. With reference parameters, the system reaches efficiencies of about 18.5%. These efficiencies are increased with a combination of improved design parameters, reaching values of between 24.1% and 26.2%, depending on the season, which are relatively good for CSP plants.« less

System Would Regulate Low Gas Pressure
NASA Technical Reports Server (NTRS)
Frazer, Robert E.
1994-01-01
System intended to maintain gases in containers at pressures near atmospheric. Includes ballast volume in form of underinflated balloon that communicates with working volume. Balloon housed in rigid chamber not subjected to extremes of temperature of working volume. Pressure in chamber surrounding balloon regulated at ambient atmospheric pressure or at constant small differential pressure above or below ambient. Expansion and contraction of balloon accommodates expansion or contraction of gas during operational heating or cooling in working volume, maintaining pressure in working volume at ambient or constant differential above or below ambient. Gas lost from system due to leakage or diffusion, low-pressure sensor responds, signaling valve actuators to supply more gas to working volume. If pressure rises too high, overpressure relief valve opens before excessive pressure damages system.
Don't Erase that Whiteboard! Archiving Student Work on a Photo-Sharing Website
NASA Astrophysics Data System (ADS)
Price, Edward; Tsui, Stephen; Hart, Alicia; Saucedo, Lydia
2011-10-01
Students in physics courses often use whiteboards to brainstorm, solve problems, and present results to the rest of the class, particularly in courses involving collaborative small group work and whole class discussions. The whiteboards contain a valuable record of students' collaborative work. Once a whiteboard is erased, however, its contents are lost and no longer accessible to students, instructors, or researchers and curriculum developers. We solve this problem using wireless-enabled digital cameras to create an archive of students' work on the photo-sharing website Flickr.com. This provides a persistent record of class activities that our students use frequently and find valuable. In this paper, we describe how this works in class and how students use the photos.

Working memory impairment is considered a core deficit in schizophrenia, but the precise nature of this deficit has not been determined. Multiple lines of evidence implicate deficits at the encoding stage. During encoding, information is held in a precategorical sensory store termed iconic memory, a literal image of the stimulus with high capacity but rapid decay. Pathologically increased iconic decay could reduce the number of items that can be transferred into working memory before the information is lost and could thus contribute to the working memory deficit seen in the illness. The current study used a partial report procedure to test the hypothesis that patients with schizophrenia (n = 37) display faster iconic memory decay than matched healthy control participants (n = 28). Six letters, arranged in a circle, were presented for 50 ms. Following a variable delay of 0–1000 ms, a central arrow cue indicated the item to be reported. In both patients and control subjects, recall accuracy decreased with increasing cue delay, reflecting decay of the iconic representation of the stimulus array. Patients displayed impaired memory performance across all cue delays, consistent with an impairment in working memory, but the rate of iconic memory decay did not differ between patients and controls. This provides clear evidence against faster loss of iconic memory representations in schizophrenia, ruling out iconic decay as an underlying source of the working memory impairment in this population. Thus, iconic decay rate can be added to a growing list of unimpaired cognitive building blocks in schizophrenia. PMID:20053864

If I slowly raise a heavy book one meter up in the air, I do positive work. This work corresponds to an energy transfer. I lose chemical food energy that is consumed by my muscles to lift the book upward. Energy is gained by the book-Earth system in the form of gravitational potential energy that is stored in the gravitational field.1 But what happens if I slowly lower the book back down by one meter to its original location? The book-Earth system loses all the energy it gained and returns to its starting configuration. I have done negative work this time. But my muscles do not regain their original chemical energy! Where did the lost energy go?

Previous studies have identified various factors related to masticatory performance. This study was aimed to investigate variations and impacts of factors related to masticatory performance among different occlusal support areas in general urban population in Japan. A total of 1875 Japanese subjects (mean age: 66·7 years) were included in the Suita study. Periodontal status was evaluated using the Community Periodontal Index (CPI). The number of functional teeth and occlusal support areas (OSA) were recorded, and the latter divided into three categories of perfect, decreased and lost OSA based on the Eichner Index. Masticatory performance was determined by means of test gummy jelly. For denture wearers, masticatory performance was measured with the dentures in place. The multiple linear regression analysis showed that, when controlling for other variables, masticatory performance was significantly associated with sex, number of functional teeth, maximum bite force and periodontal status in perfect OSA. Masticatory performance was significantly associated with number of functional teeth, maximum bite force and periodontal status in decreased OSA. In lost OSA, masticatory performance was significantly associated with maximum bite force. Maximum bite force was a factor significantly influencing masticatory performance that was common to all OSA groups. After controlling for possible confounding factors, the number of functional teeth and periodontal status were common factors in the perfect and decreased OSA groups, and only sex was significant in the perfect OSA group. These findings may help in providing dietary guidance to elderly people with tooth loss or periodontal disease. © 2015 John Wiley & Sons Ltd.

Tracking statistics between the stations and the data centers are compared periodically to eliminate lost data. Future activities in this area include sub-daily (i.e., hourly) NP data management, more stringent data integrity tests, and automatic station notification of format and data integrity issues.
Study protocol title: a prospective cohort study of low back pain
2013-01-01
Background Few prospective cohort studies of workplace low back pain (LBP) with quantified job physical exposure have been performed. There are few prospective epidemiological studies for LBP occupational risk factors and reported data generally have few adjustments for many personal and psychosocial factors. Methods/design A multi-center prospective cohort study has been incepted to quantify risk factors for LBP and potentially develop improved methods for designing and analyzing jobs. Due to the subjectivity of LBP, six measures of LBP are captured: 1) any LBP, 2) LBP ≥ 5/10 pain rating, 3) LBP with medication use, 4) LBP with healthcare provider visits, 5) LBP necessitating modified work duties and 6) LBP with lost work time. Workers have thus far been enrolled from 30 different employment settings in 4 diverse US states and performed widely varying work. At baseline, workers undergo laptop-administered questionnaires, structured interviews, and two standardized physical examinations to ascertain demographics, medical history, psychosocial factors, hobbies and physical activities, and current musculoskeletal disorders. All workers’ jobs are individually measured for physical factors and are videotaped. Workers are followed monthly for the development of low back pain. Changes in jobs necessitate re-measure and re-videotaping of job physical factors. The lifetime cumulative incidence of low back pain will also include those with a past history of low back pain. Incident cases will exclude prevalent cases at baseline. Statistical methods planned include survival analyses and logistic regression. Discussion Data analysis of a prospective cohort study of low back pain is underway and has successfully enrolled over 800 workers to date. PMID:23497211

Carbonate chimneys at the Lost City hydrothermal field are coated in biofilms dominated by a single phylotype of archaea known as Lost City Methanosarcinales. In this study, we have detected surprising physiological complexity in single-species biofilms, which is typically indicative of multispecies biofilm communities. Multiple cell morphologies were visible within the biofilms by transmission electron microscopy, and some cells contained intracellular membranes that may facilitate methane oxidation. Both methane production and oxidation were detected at 70 to 80°C and pH 9 to 10 in samples containing the single-species biofilms. Both processes were stimulated by the presence of hydrogen (H(2)), indicating that methane production and oxidation are part of a syntrophic interaction. Metagenomic data included a sequence encoding AMP-forming acetyl coenzyme A synthetase, indicating that acetate may play a role in the methane-cycling syntrophy. A wide range of nitrogen fixation genes were also identified, many of which were likely acquired via lateral gene transfer (LGT). Our results indicate that cells within these single-species biofilms may have differentiated into multiple physiological roles to form multicellular communities linked by metabolic interactions and LGT. Communities similar to these Lost City biofilms are likely to have existed early in the evolution of life, and we discuss how the multicellular characteristics of ancient hydrogen-fueled biofilm communities could have stimulated ecological diversification, as well as unity of biochemistry, during the earliest stages of cellular evolution. Our previous work at the Lost City hydrothermal field has shown that its carbonate chimneys host microbial biofilms dominated by a single uncultivated "species" of archaea. In this paper, we integrate evidence from these previous studies with new data on the metabolic activity and cellular morphology of these archaeal biofilms. We conclude that the archaeal biofilm must contain cells that are physiologically and possibly genetically differentiated with respect to each other. These results are especially interesting considering the possibility that the first cells originated and evolved in hydrothermal systems similar to Lost City.

The health indicator disability-adjusted life years combines the fatal and nonfatal consequences of a disease in a single measure. The aim of this study was to evaluate the burden of ischemic heart disease in 2008 in Spain by calculating disability-adjusted life years. The years of life lost due to premature death were calculated using the ischemic heart disease deaths by age and sex recorded in the Spanish National Institute of Statistics and the life-table in the 2010 Global Burden of Disease study. The years lived with disability, calculated for acute coronary syndrome, stable angina, and ischemic heart failure, used hospital discharge data and information from population studies. Disability weights were taken from the 2010 Global Burden of Disease study. We calculated crude and age standardized rates (European Standard Population). Univariate sensitivity analyses were performed. In 2008, 539 570 disability-adjusted life years were lost due to ischemic heart disease in Spain (crude rate, 11.8/1000 population; standardized, 8.6/1000). Of the total years lost, 96% were due to premature death and 4% due to disability. Among the years lost due to disability, heart failure accounted for 83%, stable angina 15%, and acute coronary syndrome 2%. In the sensitivity analysis, weighting by age was the factor that changed the results to the greatest degree. Ischemic heart disease continues to have a huge impact on the health of our population, mainly because of premature death. The results of this study provide an overall vision of the epidemiologic situation in Spain and could serve as the basis for evaluating interventions targeting the acute and chronic manifestations of cardiac ischemia.

It is expected that 40% to 60% of initial alveolar bone volume will be lost up to 6 months after tooth extraction. OsteoScaf(TM) (TRT, Toronto, ON, Canada) (poly (DL-lactide-co-glycololide/calcium phosphate [PLGA/CaP] scaffold) is a novel bone substitute material and represents a promising alternative for maintaining alveolar bone integrity in this clinical scenario. Here it was hypothesized that OsteoScaf would reduce alveolar bone lost after tooth extraction in patient, acting as a clot-retention device. A total of 10 patients (32 sockets) were included in the study, of which 16 sockets were grafted with OsteoScaf and 16 were used as control (coagulum alone). Cone beam computed tomography (CBCT) was performed both immediately following extraction and also at 120 days postoperatively, at which time biopsy samples were also harvested for histological analyses. Quantitative analysis of CBCT showed less bone resorption in the OsteoScaf groups, being 10.5% to 14.4% less bone lost in the center of the socket, 15.4% in the buccal region, and 12.6% in the palatal. Qualitative histological analysis showed new bone tissue in direct apposition to the scaffold - demonstrating its osteoconductive nature. OsteoScaf diminished the expected bone lost during the postextraction remodeling of the alveolar bone ridge at 120 days postextraction. © 2015 Wiley Periodicals, Inc.

Hosts may mitigate the impact of parasites by two broad strategies: resistance, which limits parasite burden, and tolerance, which limits the fitness or health cost of increasing parasite burden. The degree and causes of variation in both resistance and tolerance are expected to influence host–parasite evolutionary and epidemiological dynamics and inform disease management, yet very little empirical work has addressed tolerance in wild vertebrates. Here, we applied random regression models to longitudinal data from an unmanaged population of Soay sheep to estimate individual tolerance, defined as the rate of decline in body weight with increasing burden of highly prevalent gastrointestinal nematode parasites. On average, individuals lost weight as parasite burden increased, but whereas some lost weight slowly as burden increased (exhibiting high tolerance), other individuals lost weight significantly more rapidly (exhibiting low tolerance). We then investigated associations between tolerance and fitness using selection gradients that accounted for selection on correlated traits, including body weight. We found evidence for positive phenotypic selection on tolerance: on average, individuals who lost weight more slowly with increasing parasite burden had higher lifetime breeding success. This variation did not have an additive genetic basis. These results reveal that selection on tolerance operates under natural conditions. They also support theoretical predictions for the erosion of additive genetic variance of traits under strong directional selection and fixation of genes conferring tolerance. Our findings provide the first evidence of selection on individual tolerance of infection in animals and suggest practical applications in animal and human disease management in the face of highly prevalent parasites.

In 2007, part of a drinking water distribution system was accidentally contaminated with waste water effluent causing a gastroenteritis outbreak in a Finnish town. We examined the acute and cumulative effects of this incidence on sick leaves among public sector employees residing in the clean and contaminated areas, and the additional costs of lost workdays due to the incidence. Daily information on sick leaves of 1789 Finnish Public Sector Study participants was obtained from employers' registers. Global Positioning System-coordinates were used for linking participants to the clean and contaminated areas. Prevalence ratios (PR) for weekly sickness absences were calculated using binomial regression analysis. Calculations for the costs were based on prior studies. Among those living in the contaminated areas, the prevalence of participants on sick leave was 3.54 (95% confidence interval (CI) 2.97-4.22) times higher on the week following the incidence compared to the reference period. Those living and working in the clean area were basically not affected, the corresponding PR for sick leaves was 1.12, 95% CI 0.73-1.73. No cumulative effects on sick leaves were observed among the exposed. The estimated additional costs of lost workdays due to the incidence were 1.8-2.1 million euros. The prevalence of sickness absences among public sector employees residing in affected areas increased shortly after drinking water distribution system was contaminated, but no long-term effects were observed. The estimated costs of lost workdays were remarkable, thus, the cost-benefits of better monitoring systems for the water distribution systems should be evaluated.
Working Health Services Scotland: a 4-year evaluation.

Working Health Service Scotland (WHSS) supports the self-employed and employees of small and medium-sized enterprises (SMEs) in Scotland with a health condition affecting their ability to work, who are either absent or at risk of becoming absent due to it. To evaluate the impact on health and work outcomes of WHSS clients over a 4-year period. Data were collected at enrolment, entry, discharge and follow-up at 3 and 6 months after discharge. Clients completed up to three validated health questionnaires at entry and discharge-EuroQol five dimensions (EQ-5D) and visual analogue scale (VAS); Hospital Anxiety and Depression Scale (HADS); and Canadian Occupational Performance Measure (COPM). A total of 13463 referrals occurred in the 4-year period; 11748 (87%) were eligible and completed entry assessment and 60% of the latter completed discharge paperwork. The majority of referrals were due to musculoskeletal conditions (84%) while 12% were referred with mental health conditions. Almost a fifth (18%) of cases were absent at entry and back at work at discharge. Work days lost while in WHSS was associated with age, length of absence prior to entering WHSS, primary health condition and time in programme. All health measures showed significant improvements from entry to discharge. Improvement in general health was sustained at 3- and 6-month follow-up. The WHSS evaluation findings indicate that participation was associated with positive changes to health and return-to-work. The extent of the positive change in health measures and work ability can be highly important economically for employees and employers. © The Author(s) 2018.

Lost Productivity in Stroke Survivors: An Econometrics Analysis.

2016-01-01
Stroke leads to a substantial societal economic burden. Loss of productivity among stroke survivors is a significant contributor to the indirect costs associated with stroke. We aimed to characterize productivity and factors associated with employability in stroke survivors. We used the Canadian Community Health Survey 2011-2012 to identify stroke survivors and employment status. We used multivariable logistic models to determine the impact of stroke on employment and on factors associated with employability, and used Heckman models to estimate the effect of stroke on productivity (number of hours worked/week and hourly wages). We included data from 91,633 respondents between 18 and 70 years and identified 923 (1%) stroke survivors. Stroke survivors were less likely to be employed (adjusted OR 0.39, 95% CI 0.33-0.46) and had hourly wages 17.5% (95% CI 7.7-23.7) lower compared to the general population, although there was no association between work hours and being a stroke survivor. We found that factors like older age, not being married, and having medical comorbidities were associated with lower odds of employment in stroke survivors in our sample. Stroke survivors are less likely to be employed and they earn a lower hourly wage than the general population. Interventions such as dedicated vocational rehabilitation and policies targeting return to work could be considered to address this lost productivity among stroke survivors. © 2016 S.

Growing the Data Refuge Project into a Local Libraries+ Network Node
NASA Astrophysics Data System (ADS)
Janz, M.
2017-12-01
The Data Refuge project began as concerns were raised about the vulnerability of federal climate and environmental data. The concern stemmed from the idea that if the federal agency that curates the data lost funding, and with it staff and infrastructure, that the data could be lost. The team worked to determine what factors contributed to the vulnerability of these data and how we might mitigate their risks. After speaking with many partners and collaborators around the country who all had different roles and perspectives working with these data, we saw the landscape of government data in new ways. We began seeing potential in various initiatives to ensure continued access to these data regardless of political, technological, or other risks. One recurring theme in our assessment was that libraries would be natural backup stewards for federal data.From and with our partners, we learned just how complicated the problem of creating networks of backup stewards for government data would be, but also how important it is to make the effort. As Data Refuge moves into its next stages into the Libraries+ Network, we're making plans to work with our partners on federal, state, and local projects that address different aspects of the problem space. These projects are examples of ways to approach this problem in concert with a variety of stakeholders.
Treatment and prevention of obesity: what works, what doesn't work, and what might work.
Allison, David B; Weber, Mary T
2003-02-01
We provide a very broad conceptual overview of some of the issues involved in the treatment and prevention of obesity. Data suggest that clinicians have some ability to promote positive changes with obesity treatment. The environment, though important in influencing one's degree of adiposity, has largely transient effects that do not tend to carry over from one time to substantially later times. In contrast, the genetic influences on body mass index at any one time do tend to carry over to later times. This information influences the types of approaches that are and are not likely to be successful in terms of preventing obesity or reducing obesity on a population level. A second issue concerns the composition of weight lost. Conditional on fat loss, weight loss has been associated with an increased mortality rate (MR) whereas, conditional upon weight loss, fat loss has been associated with a decreased MR. This suggests that we should seek treatments that maximize the proportion of weight lost as fat. Third, the efficacy of current treatments is far below patients' expectations and desires. We need both to increase the efficacy of our treatments dramatically and help patients adjust their expectations so that they can take satisfaction in smaller weight losses. Perhaps, with continued efforts at enhancing treatments, we will see incremental advances in the treatment and prevention of obesity.

Organisational downsizing is common in modern work life, but its effect on employees' mental health is not known. The authors examined whether working in downsizing organisations predicts use of psychotropic drugs among employees who remain in employment. Prospective cohort study of municipal employees in Finland. 4783 employees worked in downsized units but kept their jobs after downsizing in 1993, 4271 employees lost their jobs during the downsizing, and 17 599 employees did not experience downsizing. The outcome was psychotropic drug prescriptions (antidepressants, anxiolytics and hypnotics) during 1994-2000 extracted from nationwide registers and linked to the data by means of each participant's personal identification number. After adjustment for predownsizing characteristics, employees who were exposed to downsizing but kept their jobs were at a higher risk of being prescribed psychotropic drugs (rate ratio 1.49, 95% CI 1.10 to 2.02 in men and 1.12, 95% CI 1.00 to 1.27 in women) than those not exposed to downsizing. The association of downsizing was strongest with hypnotics among the men and with anxiolytics among the women. An increased rate of psychotropic prescriptions after downsizing was also seen in male workers who lost their job (rate ratio 1.64, 95% CI 1.19 to 2.25). The association between organisational downsizing and increased use of psychotropic drugs suggests that this managerial strategy may pose mental health risks among employees.

Work-related musculoskeletal disorders (WMSDs) resulting from ergonomic hazards are common in the United States. Recent data from the Bureau of Labor Statistics (BLS) indicate that in 2011, one third of occupational injuries and illnesses resulting in lost time from work were WMSDs. Based on data from the 2010 BLS Survey of Occupational Injuries and Illnesses, a higher rate of WMSDs resulting in lost time from work occurred in the Wholesale and Retail Trade (WRT) industry compared with most other industries. To assess trends and identify WRT subsectors and subgroups associated with high rates of WMSD workers' compensation claims, the Ohio Bureau of Workers' Compensation (OBWC) and CDC analyzed OBWC claims data for single-location WRT employers in Ohio for the period 2005-2009. From 2005 to 2009, the rate of WMSD claims declined from 86.3 to 52.8 per 10,000 employees. The three WRT industry subsectors with the highest rates of WMSD claims were Merchant Wholesalers, Nondurable Goods; Furniture and Home Furnishings Stores; and Merchant Wholesalers, Durable Goods. Within those three WRT subsectors, the highest rates of WMSD claims were noted in five subgroups: furniture stores and wholesalers of alcoholic beverages, groceries and related products, metal and minerals, and motor vehicle parts. Providing recommendations for WMSD prevention is particularly important for these WRT subgroups.
Error mitigation for CCSD compressed imager data

To efficiently use the limited bandwidth available on the downlink from satellite to ground station, imager data is usually compressed before transmission. Transmission introduces unavoidable errors, which are only partially removed by forward error correction and packetization. In the case of the commonly used CCSD Rice-based compression, it results in a contiguous sequence of dummy values along scan lines in a band of the imager data. We have developed a method capable of using the image statistics to provide a principled estimate of the missing data. Our method outperforms interpolation yet can be performed fast enough to provide uninterrupted data flow. The estimation of the lost data provides significant value to end users who may use only part of the data, may not have statistical tools, or lack the expertise to mitigate the impact of the lost data. Since the locations of the lost data will be clearly marked as meta-data in the HDF or NetCDF header, experts who prefer to handle error mitigation themselves will be free to use or ignore our estimates as they see fit.

This report documents the development of constitutive material models for the overburden formations, reservoir formations, and underlying strata at the Lost Hills oil field located about 45 miles northwest of Bakersfield in Kern County, California. Triaxial rock mechanics tests were performed on specimens prepared from cores recovered from the Lost Hills field, and included measurements of axial and radial stresses and strains under different load paths. The tested intervals comprise diatomaceous sands of the Etchegoin Formation and several diatomite types of the Belridge Diatomite Member of the Monterey Formation, including cycles both above and below the diagenetic phase boundary betweenmore » opal-A and opal-CT. The laboratory data are used to drive constitutive parameters for the Extended Sandler-Rubin (ESR) cap model that is implemented in Sandia's structural mechanics finite element code JAS3D. Available data in the literature are also used to derive ESR shear failure parameters for overburden formations. The material models are being used in large-scale three-dimensional geomechanical simulations of the reservoir behavior during primary and secondary recovery.« less

We predict the impact of paid leave in increasing influenza vaccinations for employees, thus decreasing workdays lost and healthcare visits resulting from infection. Nationally representative data from the 2006-2010 Medical Expenditure Panel Survey were used. We examined working adults aged 18 and above (N=51,471). Logistic regression measured the association of paid leave with flu vaccination. We predicted the impact on labor and healthcare markets if universal paid leave were provided. The proportion of workers receiving vaccination annually was higher for those with paid leave versus without paid leave (34.0% vs. 21.0%, P<0.001). Adjusted odds of having a vaccination increased with paid leave vs. without paid leave (OR=1.42, CI: 1.31-1.53). Universal paid leave is predicted to increase vaccinations by 1.6 million, resulting in 63.8 thousand fewer absences from work and 18.2 thousand fewer healthcare visits for the flu annually. Our study suggests that employees without paid leave are significantly less likely to have had a flu vaccination. Expanding paid leave could substantially increase flu vaccination, resulting in fewer workdays lost to influenza and savings in healthcare costs. Copyright © 2014 Elsevier Ltd. All rights reserved.

Few studies have examined the impact of women's personal costs on obtaining a screening mammogram in the United States. All women obtaining screening mammograms at nine Connecticut mammography facilities during a 2-week study period were asked to complete a questionnaire. Facilities included urban and rural fixed sites and mobile sites. The survey included questions about insurance coverage, mammogram payment, and personal costs in terms of transportation, family care, parking, and lost work time from the women's perspective. The response rate was 62% (731 of 1189). Thirty-two percent of respondents incurred some type of personal cost, including lost work time, family care, and parking. Women incurring personal costs were more likely than those without personal costs to attend an urban facility (46% vs. 23%, p < 0.01) and be under the age of 50 (40% vs. 26%, p < 0.01). Overall, 61% of women listed convenience and 17% listed cost as a reason for choosing a mammography facility; 23% reported that cost might prevent them from obtaining a future mammogram. One third of women obtaining mammograms may be incurring personal costs. These personal costs should be considered in future cost-effectiveness analyses.

High-harmonic fast-wave (HHFW) heating is a heating and current-drive scheme on the National Spherical Torus eXperiment (NSTX) complimentary to neutral beam injection. Previous experiments suggest that a significant fraction, up to 50%, of the HHFW power is promptly lost to the scrape-off layer (SOL). Research indicates that the lost power reaches the divertor via wave propagation and is converted to a heat flux at the divertor through RF rectification rather than heating the SOL plasma at the midplane. This counter-intuitive hypothesis is investigated using a simplified two-point model, relating plasma parameters at the divertor to those at the midplane. Taking measurements at the divertor region of NSTX as input, this two-point model is used to predict midplane parameters, using the predicted heat flux as an indicator of power input to the SOL. These predictions are compared to measurements at the midplane to evaluate the extent to which they are consistent with experiment.

Objectives To project the number of people aged 45–64 years with lost productive life years (PLYs) due to diabetes and related costs (lost income, extra welfare payments, lost taxation revenue); and lost gross domestic product (GDP) attributable to diabetes in Australia from 2015 to 2030. Design A simulation study of how the number of people aged 45–64 years with diabetes increases over time (based on population growth and disease trend data) and the economic losses incurred by individuals and the government. Cross-sectional outputs of a microsimulation model (Health&WealthMOD2030) which used the Australian Bureau of Statistics’ Survey of Disability, Ageing and Carers 2003 and 2009 as a base population and integrated outputs from two microsimulation models (Static Incomes Model and Australian Population and Policy Simulation Model), Treasury's population and labour force projections, and chronic disease trends data. Setting Australian population aged 45–64 years in 2015, 2020, 2025 and 2030. Outcome measures Lost PLYs, lost income, extra welfare payments, lost taxation revenue, lost GDP. Results 18 100 people are out of the labour force due to diabetes in 2015, increasing to 21 400 in 2030 (18% increase). National costs consisted of a loss of $A467 million in annual income in 2015, increasing to $A807 million in 2030 (73% increase). For the government, extra annual welfare payments increased from $A311 million in 2015 to $A350 million in 2030 (13% increase); and lost annual taxation revenue increased from $A102 million in 2015 to $A166 million in 2030 (63% increase). A loss of $A2.1 billion in GDP was projected for 2015, increasing to $A2.9 billion in 2030 attributable to diabetes through its impact on PLYs. Conclusions Individuals incur significant costs of diabetes through lost PLYs and lost income in addition to disease burden through human suffering and healthcare costs. The government incurs extra welfare payments, lost taxation revenue and lost GDP, along with direct healthcare costs. PMID:28069621

In current solar cells, any photon energy exceeding the semiconductor bandgap is lost before being collected, limiting the cell performance. Hot carrier solar cells could avoid these losses. Now, a detailed experimental study and analysis shows that this strategy could lead to an improvement of the photoconversion efficiency in practice.

Algorithms that reject transient signals due to proton effects on charge coupled device (CCD) sensors have been implemented in the HDOS ASTRA-l Star Trackers to be flown on the TOPEX mission scheduled for launch in July 1992. A unique technique for simulating a proton-rich environment to test trackers is described, as well as the test results obtained. Solar flares or an orbit that passes through the South Atlantic Anomaly can subject the vehicle to very high proton flux levels. There are three ways in which spurious proton generated signals can impact tracker performance: the many false signals can prevent or extend the time to acquire a star; a proton-generated signal can compromise the accuracy of the star's reported magnitude and position; and the tracked star can be lost, requiring reacquisition. Tests simulating a proton-rich environment were performed on two ASTRA-1 Star Trackers utilizing these new algorithms. There were no false acquisitions, no lost stars, and a significant reduction in reported position errors due to these improvements.
