    2013-01-01

    The preceding articles in this volume have identified and discussed a wide range of methodological and practical issues in the development of personalized medicine. This concluding article uses the resulting insights to identify implications for the economic incentives for evidence generation. It argues that promoting an efficient path to personalized medicine is going to require appropriate incentives for evidence generation including: 1) a greater willingness on the part of payers to accept prices that reflect value; 2) consideration of some form of intellectual property protection (e.g., data exclusivity) for diagnostics to incentivize generation of evidence of clinical utility; 3) realistic expectations around the standards for evidence; and 4) public investment in evidence collection to complement the efforts of payers and manufacturers. It concludes that such incentives could build and maintain a balance among: 1) realistic thresholds for evidence and the need for payers to have confidence in the clinical utility of the drugs and tests they use; 2) payment for value, with prices that ensure cost-effectiveness for health systems; and 3) levels of intellectual property protection for evidence generation that provide a return for those financing research and development, while encouraging competition to produce both better and more efficient tests.

    Major Depressive Disorder (MDD) involves deficits in the reward system. While neuroimaging studies have focused on affective stimulus processing, few investigations have directly addressed deficits in the anticipation of incentives. We examined neural responses during gain and loss anticipation in patients with MDD before and after treatment with a selective serotonin reuptake inhibitor (SSRI). Fifteen adults with MDD and 15 healthy participants, matched for age, verbal IQ and smoking habits, were investigated in a functional magnetic resonance imaging (fMRI) study using a monetary incentive delay task. Patients were scanned drug-free and after 6 weeks of open-label treatment with escitalopram; controls were scanned twice at corresponding time points. We compared the blood oxygenation level dependent (BOLD) response during the anticipation of gain and loss with a neutral condition. A repeated measures ANOVA was calculated to identify effects of group (MDD vs. controls), time (first vs. second scan) and group-by-time interaction. Severity of depression was measured with the Hamilton Rating Scale of Depression and the Beck Depression Inventory. MDD patients showed significantly less ventral striatal activation during anticipation of gain and loss compared with controls before, but not after, treatment. There was a significant group-by-time interaction during anticipation of loss in the left ventral striatum due to a signal increase in patients after treatment. Ventral striatal hyporesponsiveness was associated with the severity of depression and in particular anhedonic symptoms. These findings suggest that MDD patients show ventral striatal hyporesponsiveness during incentive cue processing, which normalizes after successful treatment.

Exercise, smoking cessation, medication adherence, and other healthy behavior can help prevent, or even treat, some diseases. Consequently, interventions that promote healthy behavior have become increasingly common in health care settings. Many of these interventions award incentives contingent upon preventive health-related behavior. Incentive-based interventions vary considerably along several dimensions, including who is targeted in the intervention, which behavior is targeted, and what type of incentive is used. More research on the quantitative and qualitative features of many of these variables is still needed to inform treatment. However, extensive literature on basic and applied behavior analytic research is currently available to help guide the study and practice of incentive-based treatment in health care. In this integrated review, we discuss how behavior analytic research and theory can help treatment providers design and implement incentive-based interventions that promote healthy behavior.

    The German fixed rate remuneration system in psychiatry and psychosomatics (PEPP) has been criticized by many specialty associations because negative effects on mental healthcare are expected through economic incentives. Through analysis of performance data in the treatment of alcohol dependency at the Evangelical Hospital Bielefeld (Evangelisches Krankenhaus Bielefeld, EvKB) from 2014 and various simulations, the incentives of the PEPP (version 2015) were analyzed and its potential impact on patient care was evaluated. Groups of cases were created based on the clinical data. Various parameters were evaluated, such as duration of treatment, PEPP coding, loss of income by merging cases and case remuneration. Additionally, changes in the duration of treatment, the intensity of treatment and the intensity of care were simulated. In the simulations a reduction in the duration of treatment by 16.1 % led to additional revenues of 1.9 % per treatment day. The calculated additional costs of 1:1 care and intensive nursing care were not completely covered by the additional revenues, whereas psychotherapeutic inpatient treatment programs showed positive profit contributions. Complicated cases with increased merging of cases showed lower revenues but with above average expenditure of efforts. The current version of the PEPP leads to misdirected incentives in patient care. This is caused, for example, by the fact that higher profit contributions can be realized in some patient groups and intensive nursing care of patients is insufficiently represented. It is not clear whether these incentives will persist or can be compensated in subsequent versions of the system.

    Purpose: Continuous dose delivery in radiation therapy treatments has been shown to decrease total treatment time while improving the dose conformity and distribution homogeneity over the conventional step-and-shoot approach. The authors develop an inverse treatment planning method for Gamma Knife® Perfexion™ that continuously delivers dose along a path in the target. Methods: The authors’ method is comprised of two steps: find a path within the target, then solve a mixed integer optimization model to find the optimal collimator configurations and durations along the selected path. Robotic path-finding techniques, specifically, simultaneous localization and mapping (SLAM) using an extended Kalman filter, are used to obtain a path that travels sufficiently close to selected isocentre locations. SLAM is novelly extended to explore a 3D, discrete environment, which is the target discretized into voxels. Further novel extensions are incorporated into the steering mechanism to account for target geometry. Results: The SLAM method was tested on seven clinical cases and compared to clinical, Hamiltonian path continuous delivery, and inverse step-and-shoot treatment plans. The SLAM approach improved dose metrics compared to the clinical plans and Hamiltonian path continuous delivery plans. Beam-on times improved over clinical plans, and had mixed performance compared to Hamiltonian path continuous plans. The SLAM method is also shown to be robust to path selection inaccuracies, isocentre selection, and dose distribution. Conclusions: The SLAM method for continuous delivery provides decreased total treatment time and increased treatment quality compared to both clinical and inverse step-and-shoot plans, and outperforms existing path methods in treatment quality. It also accounts for uncertainty in treatment planning by accommodating inaccuracies.

    Full Text Available Severe mental illness (SMI is associated with premature cardiovascular disease, prompting the UK primary care payment-for-performance system (Quality and Outcomes Framework, QOF to incentivise annual physical health reviews. This study aimed to assess the QOF's impact on detection and treatment of cardiovascular risk factors in people with SMI.A retrospective open cohort study of UK general practice was conducted between 1996 and 2014, using segmented logistic regression with 2004 and 2011 as break points, reflecting the introduction of relevant QOF incentives in these years. 67239 SMI cases and 359951 randomly-selected unmatched controls were extracted from the Clinical Practice Research Datalink (CPRD.There was strong evidence (p≤0.015 the 2004 QOF indicator (general health resulted in an immediate increase in recording of elevated cholesterol (odds ratio 1.37 (95% confidence interval 1.24 to 1.51; obesity (OR 1.21 (1.06 to 1.38; and hypertension (OR 1.19 (1.04 to 1.38 in the SMI group compared with the control group, which was sustained in subsequent years. Similar findings were found for diabetes, although the evidence was weaker (p = 0.059; OR 1.21 (0.99 to 1.49. There was evidence (p<0.001 of a further, but unsustained, increase in recording of elevated cholesterol and obesity in the SMI group following the 2011 QOF indicator (cardiovascular specific. There was no clear evidence that the QOF indicators affected the prescribing of lipid modifying medications or anti-diabetic medications.Incentivising general physical health review for SMI improves identification of cardiovascular risk factors, although the additional value of specifically incentivising cardiovascular risk factor assessment is unclear. However, incentives do not affect pharmacological management of these risks.

  9. Taste, a new incentive to switch to (R-praziquantel in schistosomiasis treatment.

    Directory of Open Access Journals (Sweden)

    Thorsten Meyer

    Full Text Available BACKGROUND: Praziquantel (PZQ is the drug compound of choice in the control and treatment of schistosomiasis. PZQ is administered as a racemate, i. e. 1ratio1 mixture of enantiomers. The schistosomicidal activity arises from one PZQ-enantiomer, whereas the other enantiomer does not contribute to the activity. The WHO's Special Programme for Research and Training in Tropical Diseases (TDR has assigned the low-cost preparation of pure schistosomicidal (--PZQ a key priority for future R&D on PZQ, but so far this transition has not happened. PZQ has two major administration drawbacks, the first being the high dose needed, and its well documented bitter and disgusting taste. Attempts of taste-masking by low-cost means have not been successful. We hypothesized that the non-schistosomicidal component in PZQ would be the main contributor to the unpleasant taste of the drug. If the hypothesis was confirmed, the two major administration drawbacks of PZQ, the high dose needed and its bitter taste, could be addressed in one go by removing the component contributing to the bitter taste. METHODS AND FINDINGS: PZQ was separated into its schistosomicidal and the non-schistosomicidal component, the absolute stereochemical configuration of (--PZQ was determined to be (R-PZQ by X-ray crystallography, and the extent of bitterness was determined for regular racemic PZQ and the schistosomicidal component in a taste study in humans. FINDING: The schistosomicidal component alone is significantly less bitter than regular, racemic PZQ. CONCLUSION: Our hypothesis is confirmed. We propose to use only the pure schistosomicidal component of PZQ, offering the advantage of halving the dose and expectedly improving the compliance due to the removal of the bitter taste. Therefore, (R-PZQ should be specifically suitable for the treatment of school-age children against schistosomiasis. With this finding, we would like to offer an additional incentive to the TDR's recommendation to

    Missed in-center hemodialysis treatments (MHT) are a general indicator of health status in hemodialysis patients. This analysis was conducted to estimate the association between cinacalcet use and MHT rate. We studied patients receiving hemodialysis and prescription benefits services from a large dialysis organization. Incident cinacalcet users were propensity score matched to controls on 31 demographic, clinical, and laboratory variables. We applied inverse probability (IP) of censoring and crossover weights to account for informative censoring. Weighted negative binomial modeling was used to estimate MHT rates and pooled logistics models were used to estimate the association between cinacalcet use and MHT. Baseline demographic and clinical variables included serum calcium, phosphorus, parathyroid hormone, and vitamin D use, and were balanced between 15,474 new cinacalcet users and 15,474 matched controls. In an analysis based on intention-to-treat principles, 40.8% of cinacalcet users and 46.5% of nonusers were censored. MHT rate was 13% lower among cinacalcet initiators versus controls: IP of censoring weighted incidence rate ratio was 0.87 (95% confidence interval [CI]: 0.84-0.90 p < 0.001). In analyses based on as-treated principles, 72.8% and 61.5% of cinacalcet users and nonusers, respectively, crossed over or were censored. MHT rate was 15% lower among cinacalcet initiators versus controls: IP of censoring/crossover weighted incidence rate ratio was 0.85 (95%CI: 0.82-0.87 p < 0.001). After controlling for indication and differential censoring, cinacalcet treatment was associated with lower MHT rates, which may reflect better health status. Copyright © 2016 John Wiley & Sons, Ltd.

  11. The effect of reimbursement on medical decision making: do physicians alter treatment in response to a managed care incentive?

    2009-07-01

    The empirical literature that explores whether physicians respond to financial incentives has not definitively answered the question of whether physicians alter their treatment behavior at the margin. Previous research has not been able to distinguish that part of a physician response that uniformly alters treatment of all patients under a physician's care from that which affects some, but not all of a physician's patients. To explore physicians' marginal responses to financial incentives while accounting for the selection of physicians into different financial arrangements where others could not, I use data from a survey of physician visits to isolate the effect that capitation, a form of reimbursement wherein physicians receive zero marginal revenue for a range of physician provided services, has on the care provided by a physician. Fixed effects regression results reveal that physicians spend less time with their capitated patients than with their non-capitated patients.

    Contingency management interventions that provide tangible incentives based on objective indicators of drug abstinence have improved treatment outcomes of substance abusers, but have not been widely implemented in community drug abuse treatment settings. To compare outcomes achieved when a lower-cost prize-based contingency management treatment is added to usual care in community methadone hydrochloride maintenance treatment settings. Random assignment to usual care with (n = 198) or without (n = 190) abstinence incentives during a 12-week trial. Six community-based methadone maintenance drug abuse treatment clinics in locations across the United States. Three hundred eighty-eight stimulant-abusing patients enrolled in methadone maintenance programs for at least 1 month and no more than 3 years. Participants submitting stimulant- and alcohol-negative samples earned draws for a chance to win prizes; the number of draws earned increased with continuous abstinence time. Total number of stimulant- and alcohol-negative samples provided, percentage of stimulant- and alcohol-negative samples provided, longest duration of abstinence, retention, and counseling attendance. Submission of stimulant- and alcohol-negative samples was twice as likely for incentive as for usual care group participants (odds ratio, 1.98; 95% confidence interval, 1.42-2.77). Achieving 4 or more, 8 or more, and 12 weeks of continuous abstinence was approximately 3, 9, and 11 times more likely, respectively, for incentive vs usual care participants. Groups did not differ on study retention or counseling attendance. The average cost of prizes was 120 dollars per participant. An abstinence incentive approach that paid 120 dollars in prizes per participant effectively increased stimulant abstinence in community-based methadone maintenance treatment clinics.

    Radioisotopes play a significant and indispensable role in studying and understanding biological processes, viewing internal biological structures and processes for diagnosis of abnormal conditions, and in cure and alleviation of sufferings of cancer patients. With the availability of large number of diagnostic agents, SPECT and PET are matured technologies and is the mainstay of functional diagnostic imaging. Treatment of cancer with radioisotopes provides effective cure and the palliation of intractable symptoms. In a country like India, where more than 70% patients present in advanced and inoperable stages, radiation therapy plays an important role. While PET has seen the maximum growth in the last 15 years, next phase of growth of nuclear medicine is expected to be in radionuclide therapy. The new imaging modalities that appeared on the market at this very beginning of the new century and the new molecules and therapeutic technologies associated to the radioactivity open a very encouraging window that fascinates experts from other medical disciplines, and more particularly the oncologists, the hematologists and the neurologists. Cancer treatment remains at the forefront of any new therapeutic modality

    Concerns about the sustainability of current health care expenditure are focusing attention on the cost, quality and value of health care provision. Financial incentives, for example pay-for-performance (P4P), seek to reward quality and value in health care provision. There has long been an expectation that P4P schemes are coming to rheumatology. We review the available evidence about the use of incentives in this setting and provide two emerging examples of P4P schemes which may shape the future of service provision in rheumatology. Currently, there is limited and equivocal evidence in rheumatology about the impact of incentive schemes. However, reporting variation in the quality and provision of rheumatology services has highlighted examples of inefficiencies in the delivery of care. If financial incentives can improve the delivery of timely and appropriate care for rheumatology patients, then they may have an important role to play in the sustainability of health care provision.

    Offering financial incentives is an effective intervention for improving adherence in patients taking antipsychotic depot medication. We assessed whether patients' motivation for treatment might be reduced after receiving financial rewards. This study was part of Money for Medication, a multicentre, open-label, randomised controlled trial, which demonstrated the positive effects of financial incentives on antipsychotic depot compliance. Three mental healthcare institutions in Dutch secondary psychiatric care services participated. Eligible patients were aged 18-65 years, had been diagnosed with schizophrenia or another psychotic disorder, had been prescribed antipsychotic depot medication or had an indication to start using depot medication, and were participating in outpatient treatment. For 12 months, patients were randomly assigned either to treatment as usual (control group) or to treatment as usual plus a financial reward for each depot of medication received (€30 per month if fully compliant; intervention group). They were followed up for 6 months, during which time no monetary rewards were offered for taking antipsychotic medication. To assess treatment motivation after 0, 12 and 18 months, interviews were conducted using a supplement to the Health of the Nation Outcome Scales (HoNOS) and the Treatment Entry Questionnaire (TEQ). Patients were randomly assigned to the intervention (n = 84) or the control group (n = 85). After 12 months, HoNOS motivation scores were available for 131 patients (78%). Ninety-one percent of the patients had no or mild motivational problems for overall treatment; over time, there were no significant differences between the intervention and control groups. TEQ data was available for a subgroup of patients (n = 61), and showed no significant differences over time between the intervention and control groups for external motivation (β = 0.37 95% CI: -2.49 - 3.23, p = 0.799); introjected motivation (

    Cicchetti, M.A.

    1993-01-01

    Public utility regulation lacks a formal proxy for the economic profits that can be earned in an effectively competitive market if a firm is efficient or innovative. After all, public utility regulation operated on cost-plus basis. If a utility is efficient or innovative and lowers its costs, its typical reward is to have its rates reduced. This is a perverse incentive to motivate a utility to produce at the most efficient level. In addition, since regulation operates on this cost-plus basis, a utility can increase its net income, all other things being equal, by overinvesting in (or open-quotes gold-platingclose quotes) its system, another perverse incentive. Recognizing these flaws of regulation, academicians, utility executives, regulators, and legislators have tried over the last several years to implement incentive regulation plans that correct such perverse incentives. However, under many of the earnings-sharing or price-regulation incentive plans, the rewards for efficient production are not tied directly to measures under a company's control. In fact, such plans could prove highly detrimental to ratepayers and competitors of the regulated company and its affiliates. An incentive regulation plan that ties an appropriate reward for efficient production to specific efficiency gains is a better proxy of an effectively competitive environment. What's more, it is superior to an incentive plan that rewards circumstances beyond the company's control or self-serving manipulation. This is particularly true if no earnings cap is associated with the reward for efficiency. Rewards for efficient production should be tied to specific actions. A suitable incentive plan does not preclude appropriately derived flexible prices for certain products or services where warranted

    Purpose: The purpose of this study is to establish the in vivo verification of proton beam path by using proton-activated positron emission distributions. Methods: A total of 50 PET/CT imaging studies were performed on ten prostate cancer patients immediately after daily proton therapy treatment through a single lateral portal. The PET/CT and planning CT were registered by matching the pelvic bones, and the beam path of delivered protons was defined in vivo by the positron emission distribution seen only within the pelvic bones, referred to as the PET-defined beam path. Because of the patient position correction at each fraction, the marker-defined beam path, determined by the centroid of implanted markers seen in the post-treatment (post-Tx) CT, is used for the planned beam path. The angular variation and discordance between the PET- and marker-defined paths were derived to investigate the intrafraction prostate motion. For studies with large discordance, the relative location between the centroid and pelvic bones seen in the post-Tx CT was examined. The PET/CT studies are categorized for distinguishing the prostate motion that occurred before or after beam delivery. The post-PET CT was acquired after PET imaging to investigate prostate motion due to physiological changes during the extended PET acquisition. Results: The less than 2 deg. of angular variation indicates that the patient roll was minimal within the immobilization device. Thirty of the 50 studies with small discordance, referred as good cases, show a consistent alignment between the field edges and the positron emission distributions from the entrance to the distal edge. For those good cases, average displacements are 0.6 and 1.3 mm along the anterior-posterior (D{sub AP}) and superior-inferior (D{sub SI}) directions, respectively, with 1.6 mm standard deviations in both directions. For the remaining 20 studies demonstrating a large discordance (more than 6 mm in either D{sub AP} or D{sub SI}), 13

    All communities have common resources that are vulnerable to selfish motives. The current paper explores this challenge in the specific case of the urban commons, defined as the public spaces and scenery of city neighborhoods. A theoretical model differentiates between individual incentives and social incentives for caring for the commons. The quality of a commons is defined as the level of physical (e.g., loose garbage) and social (e.g., public disturbances) disorder. A first study compared levels of disorder across the census block groups of a single city; the second compared the disorder generated by individual addresses in two neighborhoods. Each study found that homeownership, an individual incentive, was the main predictor of disorder. Owner-occupied parcels generated less disorder than their renter-occupied neighbors, but both parcel types produced less disorder in a neighborhood with greater homeownership. The results emphasize the need for considering both individual and social incentives for group-beneficial behaviors.

  4. The influence of economic incentives on treatment patterns in a third-party funded dental service.

    OBJECTIVE: To investigate the response of dental practitioners to administration and remuneration adjustments to the Dental Treatment Services Scheme (DTSS) in the Republic of Ireland. DESIGN: Following the introduction of a series of administration and fee adjustments by a third party payments system in December 1999 the pattern of extractions and restorations are examined to determine whether the adjustments had influenced provider behaviour, in particular whether a substitution effect from extractions to restorations would result from a relative fee increase of 62% for amalgam fillings. DATA AND METHODS: Data on patient and provider characteristics from June 1996 to April 2005, collected by the Health Service Executive (HSE) National Shared Services Primary Care Reimbursement Service to facilitate remuneration to dentists providing services in the DTSS, was used in this analysis. A graphical analysis of the data revealed a structural break in the time-series and an apparent substitution to amalgam fillings following the introduction of the fee increases. To test the statistical significance of this break, the ratio of amalgams to restorations was regressed on the trend, growth and level dummy variables, using Ordinary Least Squares (OLS) regression. The diagnostics of the model were assessed using the Jarque-Bera normality test and the LM to test for serial correlation. RESULTS: The initial results showed no evidence of a structural break. However on further investigation, when a pulse dummy was included to account for the immediate impact of the fee adjustment the results suggest a unit root process with a structural break in December 1999. This implies that the amalgam fee increase of December 1999 influenced the behaviour patterns of providers. CONCLUSIONS: System changes can be used to change the emphasis from a scheme that was principally exodontia\\/emergency based to a scheme that is more conservative and based on restoration\\/prevention.

  5. To mitigate or not to mitigate: Regulatory treatment of emissions trading and its effect on marketplace incentives

    The Clean Air Act Amendments of 1990 (hereafter CAAA) have created a market-based mechanism that is designed to employ a profit-oriented incentive to enable electric utilities to reduce SO 2 emissions at the least cost. One of the most important challenges facing state regulatory utility commissions in the next decade is the integration of this marker-based profit-incentive process into the traditional rate-base, rate-of-return, profit-control approach to regulation. How the struggle to meld two potentially contradictory control and incentive programs will be resolved remains to be seen. As of now, it is an open question. The purpose of this paper is to help clarify some of the issues that need to be addressed and to offer some policy recommendations that will allow regulators to employ the effectiveness of market forces while they still retain overall control of the evolution of the regulated electric supply market

    The effects of the dopamine receptor agonist apomorphine, the dopamine releaser amphetamine, and the dopamine receptor antagonist cis(Z)-flupenthixol on sexual-incentive motivation and on paced-mating behavior were studied in female rats. Apomorphine, in the doses of 0.125 and 0.5 mg/kg, showed a tendency to reduce incentive motivation. Ambulatory activity was inhibited, evidenced both by diminished distance moved and reduced velocity of movement. Amphetamine (0.25 and 1 mg/kg) and flupenthixol (0.25 and 0.5 mg/kg) failed to modify incentive motivation while stimulating and reducing ambulatory activity, respectively. In the mating test, apomorphine enhanced the latency to enter the male's half and reduced the number of proceptive behaviors. However, these effects were associated with the appearance of stereotyped sniffing. Amphetamine increased the propensity to escape from the male after a mount without having other effects. Flupenthixol augmented the duration of the lordosis posture. Neither amphetamine nor flupenthixol affected sniffing. These data show that facilitated dopaminergic neurotransmission stimulates neither paced female sexual behavior nor sexual-incentive motivation. Dopamine receptor blockade has slight consequences. It is concluded that dopamine is not a transmitter of major importance for unconditioned female sexual motivation and behavior.

    What motivates community-based health workers to provide care in rural and remote areas, often on a voluntary or casual basis, is a key question for program managers and public health officials. This paper examines how a range of incentives offered as part of the Marasin Stoa Kipa program, a community-based malaria diagnosis and treatment program that has been implemented since 2007 within a major oil and gas development area in Papua New Guinea, are perceived and critiqued by community-based health workers. Nineteen interviews and seven focus group discussions with the workers who deliver services and members of the communities served by the program, conducted between November 4 and 25, 2015, reveal a pattern of mixed motivations and changes in motivation over time. This can be attributed partly to the unique social and economic circumstances in which the program is operating. Changes in the burden of disease as well as in global and national health services policy with implications for local level program operations also had an impact, as did the nature of relationships between program managers, community-based health workers, and program beneficiaries. Overall, the findings suggest that while financial and in-kind incentives can be a useful tool to motivate voluntary or minimally-compensated community-based health workers, they must be carefully structured to align with local social, economic, and epidemiological realities over the long-term.

    Poor adherence to treatment diminishes its individual and public health benefit. Financial incentives, provided on the condition of treatment attendance, could address this problem. Injecting drug users are a high-risk group for hepatitis B virus (HBV) infection and transmission, but adherence to vaccination programmes is poor. We aimed to assess whether contingency management delivered in routine clinical practice increased the completion of HBV vaccination in individuals receiving opioid substitution therapy. In our cluster randomised controlled trial, we enrolled participants at 12 National Health Service drug treatment services in the UK that provided opioid substitution therapy and nurse-led HBV vaccination with a super-accelerated schedule (vaccination days 0, 7, and 21). Clusters were randomly allocated 1:1:1 to provide vaccination without incentive (treatment as usual), with fixed value contingency management (three £10 vouchers), or escalating value contingency management (£5, £10, and £15 vouchers). Both contingency management schedules rewarded on-time attendance at appointments. The primary outcome was completion of clinically appropriate HBV vaccination within 28 days. We also did sensitivity analyses that examined vaccination completion with full adherence to appointment times and within a 3 month window. The trial is registered with Current Controlled Trials, number ISRCTN72794493. Between March 16, 2011, and April 26, 2012, we enrolled 210 eligible participants. Compared with six (9%) of 67 participants treated as usual, 35 (45%) of 78 participants in the fixed value contingency management group met the primary outcome measure (odds ratio 12·1, 95% CI 3·7-39·9; pcontingency management group (14·0, 4·2-46·2; pcontingency management to promote adherence to vaccination programmes.

    Provision of financial incentives is a promising intervention for improving adherence in patients taking antipsychotic medication. We aimed to assess the effectiveness of this intervention for improving adherence to antipsychotic depot medication in patients with psychotic disorders, irrespective of their previous compliance. We did this multicentre, open-label, randomised controlled trial at three mental health-care institutions in secondary psychiatric care services in the Netherlands. Eligible patients were aged 18-65 years, had been diagnosed with schizophrenia or another psychotic disorder, had been prescribed antipsychotic depot medication or had an indication to start using depot medication, and were participating in outpatient treatment. Patients were randomly assigned (1:1), via computer-generated randomisation with a block size of four, to receive 12 months of either treatment as usual plus a financial reward for each depot of medication received (€30 per month if fully compliant; intervention group) or treatment as usual alone (control group). Randomisation was stratified by treatment site and suspected prognostic factors: sex, comorbid substance-use disorder (absent vs present), and compliance with antipsychotic medication in the 4 months before baseline (taking antipsychotic medication. We did analysis by intention to treat. This trial is registered with the Nederlands Trial Register, number NTR2350. Between May 21, 2010, and Oct 15, 2014, we randomly assigned 169 patients to the intervention group (n=84) or the control group (n=85). Primary outcome data were available for 155 (92%) patients. At baseline, the mean MPR was 76·0% (SD 28·2%) in the intervention group versus 77·9% (28·5%) in the control group. At 12 months, the mean MPR was higher in the intervention group (94·3% [SD 11·3%]) than in the control group (80·3% [19·1%]), with an adjusted difference of 14·9% (95% CI 8·9-20·9%; pcontrol group (adjusted difference 6·5%, 95% CI 2·0

    Collagen and hyaluronan are the most abundant components of the extracellular matrix (ECM) and their overexpression in tumors is linked to increased tumor growth and metastasis. These ECM components contribute to a protective tumor microenvironment by supporting a high interstitial fluid pressure and creating a tortuous setting for the convection and diffusion of chemotherapeutic small molecules, antibodies, and nanoparticles in the tumor interstitial space. This review focuses on the research efforts to deplete extracellular collagen with collagenases to normalize the tumor microenvironment. Although collagen synthesis inhibitors are in clinical development, the use of collagenases is contentious and clinically untested in cancer patients. Pretreatment of murine tumors with collagenases increased drug uptake and diffusion 2-10-fold. This modest improvement resulted in decreased tumor growth, but the benefits of collagenase treatment are confounded by risks of toxicity from collagen breakdown in healthy tissues. In this review, we evaluate the published in vitro and in vivo benefits and limitations of collagenase treatment to improve drug delivery.

  19. Photovoltaic Incentive Design Handbook

    Hoff, T. E.

    2006-12-01

    Investments in customer-owned grid-connected photovoltaic (PV) energy systems are growing at a steady pace. This is due, in part, to the availability of attractive economic incentives offered by public state agencies and utilities. In the United States, these incentives have largely been upfront lump payments tied to the system capacity rating. While capacity-based ''buydowns'' have stimulated the domestic PV market, they have been criticized for subsidizing systems with potentially poor energy performance. As a result, the industry has been forced to consider alternative incentive structures, particularly ones that pay based on long-term measured performance. The industry, however, lacks consensus in the debate over the tradeoffs between upfront incentive payments versus longer-term payments for energy delivery. This handbook is designed for agencies and utilities that offer or intend to offer incentive programs for customer-owned PV systems. Its purpose is to help select, design, and implement incentive programs that best meet programmatic goals. The handbook begins with a discussion of the various available incentive structures and then provides qualitative and quantitative tools necessary to design the most appropriate incentive structure. It concludes with program administration considerations.

    Shortages of rigs and personnel have encouraged discussion of designing incentive contracts in the drilling sector. However, for the drilling contracts, there are not a large variety of contract types in use. This article describes and analyses incentives for drilling contractors. These are directly represented by the compensation formats utilised in the present and in the consecutive drilling contracts. Indirectly, incentives are also provided by the evaluation criteria that oil companies use for awarding drilling assignments. Changes in contract format pose a number of relevant questions relating to resource management, and the article takes an in-depth look at some of these. Do evaluation criteria for awarding drilling assignments encourage the development of new technology and solutions? How will a stronger focus on drilling efficiency influence reservoir utilisation?

    The problem of robust line planning requests for a set of origin-destination paths (lines) along with their frequencies in an underlying railway network infrastructure, which are robust to fluctuations of real-time parameters of the solution. In this work, we investigate a variant of robust line planning stemming from recent regulations in the railway sector that introduce competition and free railway markets, and set up a new application scenario: there is a (potentially large) number of line operators that have their lines fixed and operate as competing entities issuing frequency requests, while the management of the infrastructure itself remains the responsibility of a single entity, the network operator. The line operators are typically unwilling to reveal their true incentives, while the network operator strives to ensure a fair (or socially optimal) usage of the infrastructure, e.g., by maximizing the (unknown to him) aggregate incentives of the line operators.

    2004-05-01

    While interest in understanding the incentives to change among individuals with substance abuse disorders is growing, little is known about incentives among adolescents with substance abuse disorders who are participating in formal services. The present research assesses the degree and nature of motivation and treatment readiness among adolescents admitted to substance abuse services, and whether such factors vary across significant subgroups of youth based on their social, legal, or clinical profiles. Data are based on interviews with 249 youth between 12 and 18 years of age who have been admitted to either inpatient, residential, or outpatient substance abuse treatment. Measures are adapted from an instrument developed to assess multiple domains of motivation to change (e.g., intrinsic and extrinsic motivation, treatment readiness). Results suggest that the incentive to change among adolescents with substance-abusing behavior is modest at best, regardless of dimension. Nonetheless, ethnicity, type of substance use, and psychopathology significantly predict incentives to change, though the predictors depend on which dimension is considered. The most robust predictor of incentives is the severity of negative consequences associated with youth's substance use--the greater the severity, the greater the incentives. Findings underscore the need to examine the utility and dimensionality of incentive for treatment planning, while at the same time, they identify factors that treatment planners can consider as they seek ways to enhance incentives and help adolescents with substance use disorders attain positive outcomes.

    The incentives for separating and eliminating various elements from radioactive waste prior to final geologic disposal were investigated. Exposure pathways to humans were defined, and potential radiation doses to an individual living within the region of influence of the underground storage site were calculated. The assumed radionuclide source was 1/5 of the accumulated high-level waste from the US nuclear power economy through the year 2000. The repository containing the waste was assumed to be located in a reference salt site geology. The study required numerous assumptions concerning the transport of radioactivity from the geologic storage site to man. The assumptions used maximized the estimated potential radiation doses, particularly in the case of the intrusion water well scenario, where hydrologic flow field dispersion effects were ignored. Thus, incentives for removing elements from the waste tended to be maximized. Incentives were also maximized by assuming that elements removed from the waste could be eliminated from the earth without risk. The results of the study indicate that for reasonable disposal conditions, incentives for partitioning any elements from the waste in order to minimize the risk to humans are marginal at best

    Gender differences have been observed in the pathogenesis of gambling disorder and gambling related urge and cognitions are predictive of relapse to problem gambling. A better understanding of these mechanisms concurrently may help in the development of more directed therapies. We evaluated gender effects on behavioural and cognitive paths to gambling disorder from self-report data. Participants (N=454) were treatment-seeking problem gamblers on first presentation to a gambling therapy service between January 2012 and December 2014. We firstly investigated if aspects of gambling related urge, cognitions (interpretive bias and gambling expectancies) and gambling severity were more central to men than women. Subsequently, a full structural equation model tested if gender moderated behavioural and cognitive paths to gambling severity. Men (n=280, mean age=37.4years, SD=11.4) were significantly younger than women (n=174, mean age=48.7years, SD=12.9) (pgambling severity, gambling related urge, interpretive bias and gambling expectancies. The paths for urge to gambling severity and interpretive bias to gambling severity were stronger for men than women and statistically significant (pgambling expectancies to gambling severity were insignificant for both men and women. This study detected an important signal in terms of theoretical mechanisms to explaining gambling disorder and gender differences. It has implications for treatment development including relapse prevention. Copyright © 2014 Elsevier Ltd. All rights reserved.

  16. R&D Incentives for Neglected Diseases

    Science.gov (United States)

    Dimitri, Nicola

    2012-01-01

    Neglected diseases are typically characterized as those for which adequate drug treatment is lacking, and the potential return on effort in research and development (R&D), to produce new therapies, is too small for companies to invest significant resources in the field. In recent years various incentives schemes to stimulate R&D by pharmaceutical firms have been considered. Broadly speaking, these can be classified either as ‘push’ or ‘pull’ programs. Hybrid options, that include push and pull incentives, have also become increasingly popular. Supporters and critics of these various incentive schemes have argued in favor of their relative merits and limitations, although the view that no mechanism is a perfect fit for all situations appears to be widely held. For this reason, the debate on the advantages and disadvantages of different approaches has been important for policy decisions, but is dispersed in a variety of sources. With this in mind, the aim of this paper is to contribute to the understanding of the economic determinants behind R&D investments for neglected diseases by comparing the relative strength of different incentive schemes within a simple economic model, based on the assumption of profit maximizing firms. The analysis suggests that co-funded push programs are generally more efficient than pure pull programs. However, by setting appropriate intermediate goals hybrid incentive schemes could further improve efficiency. PMID:23284648

    Incentive schemes for teams are compared. I ask: under which conditions are relational incentive contracts based on joint performance evaluation, relative performance evaluation and independent performance evaluation self-enforceable. The framework of Che and Yoo (2001) on team incentives is combined with the framework of Baker, Gibbons and Murphy (2002) on relational contracts. In a repeated game between one principal and two agents, I find that incentives based on relative or independent performance are expected to dominate when the productivity of effort is high, while joint performance evaluation dominates when productivity is low. Incentives based on independent performance are more probable if the agents own critical assets. (author)

  20. Risk management versus incentives

    2006-01-01

    Portfolio theory indicates that risk management should take place at the group level. Hedging at the project level or in the individual business areas may lead to suboptimal results. However, the efficiency of a profit centre depends on its management's being able to influence factors that are crucial to the unit's financial results. Price hedging could be one such factor. In the wider perspective, this constitutes part of the balancing between centralisation and decentralisation. This article covers important elements of risk management and incentive design. It goes on to discuss the balancing of overall risk management at the group level and incentive design in profit centres and corporate units. Throughout the article, the oil industry serves as a case. (author)

    Many college students may experience mental health problems but do not seek treatment from mental health professionals. The present study examined how perceived stigma and self-stigma toward seeking mental health treatment, as well as perceptions of self-reliance for coping with mental health problems, relate to college student treatment-seeking. In total, 246 students completed a self-report survey that included measures of perceived stigma and self-stigma for treatment-seeking, self-reliance for addressing mental health concerns, self-reported mental health problems, symptoms of depression and alcohol-related problems, attitudes toward treatment-seeking, and treatment-seeking behavior. Regression analyses revealed that higher perceived stigma, self-stigma, and self-reliance were all related to a more negative attitude toward treatment-seeking. In a 3-path mediation model, bootstrapping results indicated an indirect effect where perceived stigma was related to attitude toward treatment-seeking and treatment-seeking behaviors through self-stigma and self-reliance. Specifically, higher perceived stigma was related to higher self-stigma, higher self-stigma was related to higher self-reliance, and higher self-reliance was associated with a more negative attitude toward treatment-seeking in the overall sample, and a decreased probability of having sought treatment among those who screened positive for a mental health problem. Perceived stigma may influence whether or not college students seek treatment for mental health problems by potentially increasing stigmatizing attitudes toward themselves and increasing preferences for handling problems on their own. Researchers and practitioners are recommended to seek a better understanding of the complex treatment barriers to reduce stigma and facilitate treatment-seeking. (c) 2015 APA, all rights reserved).

  5. Incentives, health promotion and equality.

    Science.gov (United States)

    Voigt, Kristin

    2012-07-01

    The use of incentives to encourage individuals to adopt 'healthier' behaviours is an increasingly popular instrument in health policy. Much of the literature has been critical of 'negative' incentives, often due to concerns about equality; 'positive' incentives, however, have largely been welcomed as an instrument for the improvement of population health and possibly the reduction of health inequalities. The aim of this paper is to provide a more systematic assessment of the use of incentives from the perspective of equality. The paper begins with an overview of existing and proposed incentive schemes. I then suggest that the distinction between 'positive' and 'negative' incentives - or 'carrots' and 'sticks' - is of limited use in distinguishing those incentive schemes that raise concerns of equality from those that do not. The paper assesses incentive schemes with respect to two important considerations of equality: equality of access and equality of outcomes. While our assessment of incentive schemes will, ultimately, depend on various empirical facts, the paper aims to advance the debate by identifying some of the empirical questions we need to ask. The paper concludes by considering a number of trade-offs and caveats relevant to the assessment of incentive schemes.

Studies performed by the Center for Health Incentives and Behavioral Economics at the University of Pennsylvania published between January 2006 and March 2014. Randomized, controlled trials with available participant-level data. Studies that did not use financial incentives to promote health behavior change were excluded. Participant-level data from seven studies were pooled. Meta-analysis on the pooled sample using a random-effects model with interaction terms to examine treatment effects and whether they varied by incentive structure or demographic characteristics. The pooled study sample comprised 1403 participants, of whom 35% were female, 70% were white, 24% were black, and the mean age was 48 years (standard deviation 11.2 years). In the fully adjusted model, participants offered financial incentives had higher odds of behavior change (odds ratio [OR]: 3.96; p financial incentives and gender, age, race, income, or education. When further adjusting for incentive structure, blacks had higher odds than whites of achieving behavior change (OR: 1.67; p Financial incentives designed using concepts from behavioral economics were effective for promoting health behavior change. There were no large and consistent relationships between the effectiveness of financial incentives and observable demographic characteristics. Second-order examinations of incentive structure suggest potential relationships among the effectiveness of financial incentives, incentive structure, and the demographic characteristics of race and income.

    The U.S. Department of Energy (DOE) Richland Operations Office (RL) has adopted the 2015 Vision for Cleanup of the Hanford Site. The CH2M HILL Plateau Remediation Company's (CHPRC) Waste and Fuels Management Project (W and FMP) and their partners support this mission by providing centralized waste management services for the Hanford Site waste generating organizations. At the time of the CHPRC contract award (August 2008) slightly more than 9,000 cubic meters (m 3 ) of legacy waste was defined as ''no-path-forward waste.'' A significant portion of this waste (7,650 m 3 ) comprised wastes with up to 50 grams of special nuclear materials (SNM) in oversized packages recovered during retrieval operations and large glove boxes removed from Hanford's Plutonium Finishing Plant (PFP). Through a collaborative effort between the DOE, CHPRC, and Perma-Fix Environmental Services, Inc. (PESI), pathways for these problematic wastes were developed and are currently being implemented.

  9. The Wisconsin experience with incentives for demand-side management

    Landgren, D.A.

    1990-01-01

    It has been noted that, within traditional regulatory frameworks for electric utilities, factors exist which discourage demand side management (DSM) and that there is a lack of positive incentives for DSM. Regulatory agencies should therefore make it possible for DSM measures to benefit from the same treatment as supply-side measures. The Wisconsin Public Service Commission (WPSC) has recognized this need and has adopted various measures accordingly. The need for efficiency incentives is described according to the particular experience of Wisconsin Electric concerning their recourse to a DSM incentive and according to new incentive models being tested in collaboration with other electricity suppliers in Wisconsin. The WPSC has concluded that the fact of considering the costs relating to DSM as expenses or capitalizing them within the rate base does not motivate the utility to promote DSM programs. The WPSC has thus decided to experiment with energy efficiency incentives in order to evaluate their eventual impact. The choice of the type of incentive had an objective of starting the process in an area where the lack of experience has created, from the regulatory point of view, a reticence on the part of utilities to engage in DSM programs. The WPSC has designed a variety of incentive models which have been adapted to each utility's own situation. Specific incentive programs developed for three Wisconsin utilities are reviewed

    Material or financial incentives are widely used in an attempt to precipitate or reinforce behaviour change, including smoking cessation. They operate in workplaces, in clinics and hospitals, and to a lesser extent within community programmes. In this third update of our review we now include trials conducted in pregnant women, to reflect the increasing activity and resources now targeting this high-risk group of smokers. To determine whether incentives and contingency management programmes lead to higher long-term quit rates. We searched the Cochrane Tobacco Addiction Group Specialised Register, with additional searches of MEDLINE, EMBASE, CINAHL and PsycINFO. The most recent searches were in December 2014, although we also include two trials published in 2015. We considered randomised controlled trials, allocating individuals, workplaces, groups within workplaces, or communities to experimental or control conditions. We also considered controlled studies with baseline and post-intervention measures. We include studies in a mixed-population setting (e.g. community-, work-, institution-based), and also, for this update, trials in pregnant smokers. One author (KC) extracted data and a second (JH-B) checked them. We contacted study authors for additional data where necessary. The main outcome measure in the mixed-population studies was abstinence from smoking at longest follow-up, and at least six months from the start of the intervention. In the trials of pregnant smokers abstinence was measured at the longest follow-up, and at least to the end of the pregnancy. Twenty-one mixed-population studies met our inclusion criteria, covering more than 8400 participants. Ten studies were set in clinics or health centres, one in Thai villages served by community health workers, two in academic institutions, and the rest in worksites. All but six of the trials were run in the USA. The incentives included lottery tickets or prize draws, cash payments, vouchers for goods and

  11. Federal tax incentives affecting coal and nuclear power economics

    International Nuclear Information System (INIS)

    Chapman, D.

    1982-01-01

    This paper analyzes the effect of federal corporate income tax incentives on coal and nuclear power developments. It estimates (1) the magnitudes of tax incentives in relationship to utility costs, (2) the relative magnitude of benefits going to coal and nuclear facilities, and (3) the influence which the time paths of tax payments and after-tax net income have upon possible incentives for premature construction and excess capacity. Utility planners currently believe that nuclear power enjoys an after-tax competitive advantage over coal plants. Investigation of investment-related credits, deductions, and exclusions in the Internal Revenue Code shows that nuclear power enjoys a more favorable tax subsidy because of its greater capital intensity. In the absence of tax subsidies, no utility would prefer nuclear power to coal generation. Tax changes now under consideration could increase the tax benefits to both without disturbing the differential advantage held by nuclear power. 43 references, 2 figures, 4 tables

    Full Text Available Incentives can promote adult wellness. We sought to examine whether incentives might help overcome barriers to engagement in child weight management programs and the ideal value, type and recipient of incentives. In 2017, we conducted semi-structured phone interviews with parents of children ≤17 years old, formerly or currently affected by obesity, who had (n = 11 or had never (n = 12 participated in family-based behavioral treatment (FBT for obesity. Interviews explored the range and type of incentives families would be willing to accept. Interview transcripts were coded and data were analyzed using a thematic analysis. We found that some parents were skeptical about receiving cash incentives. However, once treatment-related costs were identified, some became more interested in reimbursement for out of pocket expenditures. Most parents felt up to $100/month would be adequate and that incentives should be tied to changing behaviors, not BMI. Some interviewees expressed preferences for non-cash incentives (e.g. a gift card over cash incentives. Parents were willing to share incentives with adolescents, up to $50/month, but there was concern about incentives affecting a child's intrinsic motivation for behavior change. All parents acknowledged that moderate incentives alone couldn't overcome the realities of structural and familial barriers to engaging in weight management programs. In summary, we identified aspects of an incentive program to promote engagement in FBT that would be desirable and feasible to implement. Future quantitative work can reveal the value and structure of incentives that are effective for improving obesogenic health behaviors and outcomes.

    Financial and in-kind incentives have been shown to improve outcomes along the HIV care cascade, however the potential mechanismsthrough which they work remain unclear. To identify the pathways through which incentives improve retention in care and adherence to antiretroviral therapy (ART), we conducted a qualitative study with participants in a trial evaluating conditional food and cash incentives for HIV-positive food insecure adults in Shinyanga, Tanzania. We found that the incentives acted through three pathways to potentially increase retention in care and adherence to ART: (1) addressing competing needs and offsetting opportunity costs associated with clinic attendance, (2) alleviating stress associated with attending clinic and meeting basic needs, and (3) by potentially increasing motivation. Participants did not report any harmful events associated with the incentives, but reported myriad beneficial effects on household welfare. Understanding how incentives are used and how they impact outcomes can improve the design of future interventions.

  16. The barriers to patient-driven treatment in mental health: why patients may choose to follow their own path.

    2006-01-01

    The paper aims to explore the barriers that currently exist to patient-driven treatment within the field of mental health care and reform. This study represents action learning research using grounded theory to explore a possible causal basis for recidivism related to non-compliance with medication. Interviews addressed concerns from the literature around perceived barriers to patient-driven treatment evidenced by non-compliance with medically recommended pharmaceutical treatment. Results were correlated to look for emergent themes that were used to form the basis for subsequent interview questions. An analysis of the resulting emergent themes illustrated the importance of participatory treatment and coaching rather than medically applied paternalistic care, which is seen as encouraging learned helplessness on the part of patients. Similar helplessness was also revealed in clinicians themselves. Patients' awareness of their own needs and demands for more services place clients and the caregivers at odds over appropriate care in an environment of limited resources. The research was limited to only a small number of interviewees in one institution, all of whom were closely associated with mental illness in various capacities. The grounded theory nature of the research does, however, provide a framework for more research in other institutions to test and further explore some of the findings. The study demonstrated a reinforcement of Maslow's theory of needs hierarchy. The study illustrated a step-wise approach to treatment to decrease the rate of failure and recidivism in mental health care. The provision of a stable living environment was viewed as instrumental in improving patients' compliance with pharmaceutical treatment. An action plan was therefore created to initiate the support of a transitional/emergency house by various community groups in partnership with pharmaceutical manufacturing companies. Recidivism in mental health-created by non-compliance in

    Both Bohmian mechanics, a version of quantum mechanics with trajectories, and Feynman's path integral formalism have something to do with particle paths in space and time. The question thus arises how the two ideas relate to each other. In short, the answer is, path integrals provide a re-formulation of Schroedinger's equation, which is half of the defining equations of Bohmian mechanics. I try to give a clear and concise description of the various aspects of the situation. (letters and comments)

    No controlled trials in children with end-stage kidney disease have assessed the benefits of more frequently administered hemodialysis (HD). We conducted a multicenter, crossover pilot trial to determine if short, more frequent (5 days per week) in-center HD was feasible and associated with improvements in blood pressure compared with three conventional HD treatments per week. Because adult studies have not controlled for the weekly duration of dialysis, we fixed the total treatment time at 12 h a week of dialysis during two 3-month study periods; only frequency varied from 5 to 3 days per week between study periods. Eight children (median age 16.7 years) consented at three children's hospitals. The prespecified primary composite outcome was a sustained 10% decrease in systolic blood pressure and/or a decrease in antihypertensive medications relative to each study period's baseline. Among the six patients completing both study periods, five (83.3%) experienced the primary outcome during HD performed 5 days per week but not 3 days per week; one of the six (16.7%) achieved that outcome during 3-day but not 5-day (p = 0.22) per week HD. During 5-day HD, all patients had significantly more treatments during which their pre-HD systolic (p = 0.01) or diastolic (p = 0.01) blood pressure was 10% lower than baseline. We observed that more frequent HD sessions per week was feasible and associated with improved blood pressure control, but barriers to changing thrice-weekly standard of care include financial reimbursement and the time demands associated with more frequent treatments.

    2018-01-01

    This book describes and characterizes an extension to the classical path coupling method applied to statistical mechanical models, referred to as aggregate path coupling. In conjunction with large deviations estimates, the aggregate path coupling method is used to prove rapid mixing of Glauber dynamics for a large class of statistical mechanical models, including models that exhibit discontinuous phase transitions which have traditionally been more difficult to analyze rigorously. The book shows how the parameter regions for rapid mixing for several classes of statistical mechanical models are derived using the aggregate path coupling method.

  4. Incentives to promote family planning.

    2012-11-01

    Over the past 60 years, population control has become an increasingly urgent issue worldwide as a growing population strains already limited resources. The use of financial incentives to promote family planning is an innovative approach that has potential to make a contribution to efforts to better manage population growth. This report reviews eight studies that examined the effect of incentives on family planning. Published studies that tested the impact of incentives to promote some aspect of family planning and included an appropriate control or comparison condition were reviewed. Incentives have been used to promote attendance at contraceptive education sessions, adoption and continuation of contraceptive methods, sterilization, and to limit family size. All but one of the eight studies reviewed reported positive outcomes, but weaknesses in study design and execution limit the strength of the conclusions that can be drawn. Review of this literature suggests that family planning behaviors, like other behaviors, are sensitive to incentives. Given the tremendous need for efficacious interventions in global efforts to manage population growth, further research on this topic using more rigorous experimental methods is warranted.

  5. Path integrals on curved manifolds

    Grosche, C.; Steiner, F.

    1987-01-01

    A general framework for treating path integrals on curved manifolds is presented. We also show how to perform general coordinate and space-time transformations in path integrals. The main result is that one has to subtract a quantum correction ΔV ∝ ℎ 2 from the classical Lagrangian L, i.e. the correct effective Lagrangian to be used in the path integral is L eff = L-ΔV. A general prescription for calculating the quantum correction ΔV is given. It is based on a canonical approach using Weyl-ordering and the Hamiltonian path integral defined by the midpoint prescription. The general framework is illustrated by several examples: The d-dimensional rotator, i.e. the motion on the sphere S d-1 , the path integral in d-dimensional polar coordinates, the exact treatment of the hydrogen atom in R 2 and R 3 by performing a Kustaanheimo-Stiefel transformation, the Langer transformation and the path integral for the Morse potential.

    1995-01-01

    The mode of payment creates powerful incentives affecting provider behavior and the efficiency, equity and quality outcomes of health finance reforms. This article examines provider incentives as well as administrative costs, and institutional conditions for successful implementation associated with provider payment alternatives. The alternatives considered are budget reforms, capitation, fee-for-service, and case-based reimbursement. We conclude that competition, whether through a regulated private sector or within a public system, has the potential to improve the performance of any payment method. All methods generate both adverse and beneficial incentives. Systems with mixed forms of provider payment can provide tradeoffs to offset the disadvantages of individual modes. Low-income countries should avoid complex payment systems requiring higher levels of institutional development.

  7. Node-Dependence-Based Dynamic Incentive Algorithm in Opportunistic Networks

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Opportunistic networks lack end-to-end paths between source nodes and destination nodes, so the communications are mainly carried out by the “store-carry-forward” strategy. Selfish behaviors of rejecting packet relay requests will severely worsen the network performance. Incentive is an efficient way to reduce selfish behaviors and hence improves the reliability and robustness of the networks. In this paper, we propose the node-dependence-based dynamic gaming incentive (NDI algorithm, which exploits the dynamic repeated gaming to motivate nodes relaying packets for other nodes. The NDI algorithm presents a mechanism of tolerating selfish behaviors of nodes. Reward and punishment methods are also designed based on the node dependence degree. Simulation results show that the NDI algorithm is effective in increasing the delivery ratio and decreasing average latency when there are a lot of selfish nodes in the opportunistic networks.

    Alternative Energy Generation Sources are turning relevant in several countries worldwide because of technology improvement and the environmental treatment. In this paper, the most common problems of renewable energy sources are accomplished, different incentives and regulatory mandates from several countries are exposed, and a first theoretical approach to a renewable energies incentive system in Colombia is discussed. The paper is fundamentally in theoretical aspects and international experience in renewable energies incentives to accelerate their diffusion; features are analyzed towards a special incentive system for renewable energies in Colombia. As a conclusion, in Colombia will be apply indirect incentives like low interest rate, taxes exemptions and so on. But these incentives are applied to limit the support of electricity productivity in generating organizations.

  10. Conflicting Incentives Risk Analysis: A Case Study of the Normative Peer Review Process

    2015-07-01

    Full Text Available This paper presents an approach to conduct risk assessments of complex incentive systems, using a case study of the normative Peer Review Process (PRP. This research centers on appliances and adaptations of the Conflicting Incentives Risk Analysis (CIRA. First as an approach to Root Cause Analysis of a known incident, and then for a full assessment of the incentives in the PRP together with possible risk treatments. CIRA uses an alternative notion of risk, where risk modeling is in terms of conflicting incentives between the risk owner and the stakeholders concerning the execution of actions. Compared to traditional risk assessment approaches, CIRA provides an insight into the underlying incentives behind a risk, and not just the technical vulnerability, likelihood and consequence. The main contributions of this work are an approach to obtain insight into incentives as root causes, and an approach to detecting and analyzing risks from incentives in the normative PRP. This paper also discusses risk treatments in terms of incentives to make the PRP more robust, together with a discussion of how to approach risk analysis of incentives.

    1992-01-01

    I offer a pedagogical review of the homotopy arguments for fractional statistics in two dimensions. These arguments arise naturally in path-integral language since they necessarily consider the properties of paths rather than simply permutations. The braid group replaces the permutation group as the basic structure for quantum statistics; hence properties of the braid group on several surfaces are briefly discussed. Finally, the question of multiple (real-space) occupancy is addressed; I suggest that the ''traditional'' treatment of this question (ie, an assumption that many-anyon wavefunctions necessarily vanish for multiple occupancy) needs reexamination

  16. Variation in Incentive Effects across Neighbourhoods

    Directory of Open Access Journals (Sweden)

    Mark J Hanly

    2014-03-01

    Full Text Available Small monetary incentives increase survey cooperation rates, however evidence suggests that the appeal of incentives may vary across sample subgroups. Fieldwork budgets can be most effectively distributed by targeting those subgroups where incentives will have the strongest appeal. We examine data from a randomised experiment implemented in the pilot phase of the Irish Longitudinal Study of Ageing, which randomly assigned households to receive a higher (€25 or lower (€10 incentive amount. Using a random effects logistic regression model, we observe a variable effect of the higher incentive across geographic neighbourhoods. The higher incentive has the largest impact in neighbourhoods where baseline cooperation is low, as predicted by Leverage-Saliency theory. Auxiliary neighbourhood-level variables are linked to the sample frame to explore this variation further, however none of these moderate the incentive effect, suggesting that richer information is needed to identify sample subgroups where incentive budgets should be directed.

  17. Fractional path planning and path tracking

    International Nuclear Information System (INIS)

    Melchior, P.; Jallouli-Khlif, R.; Metoui, B.

    2011-01-01

    This paper presents the main results of the application of fractional approach in path planning and path tracking. A new robust path planning design for mobile robot was studied in dynamic environment. The normalized attractive force applied to the robot is based on a fictitious fractional attractive potential. This method allows to obtain robust path planning despite robot mass variation. The danger level of each obstacles is characterized by the fractional order of the repulsive potential of the obstacles. Under these conditions, the robot dynamic behavior was studied by analyzing its X - Y path planning with dynamic target or dynamic obstacles. The case of simultaneously mobile obstacles and target is also considered. The influence of the robot mass variation is studied and the robustness analysis of the obtained path shows the robustness improvement due to the non integer order properties. Pre shaping approach is used to reduce system vibration in motion control. Desired systems inputs are altered so that the system finishes the requested move without residual vibration. This technique, developed by N.C. Singer and W.P.Seering, is used for flexible structure control, particularly in the aerospace field. In a previous work, this method was extended for explicit fractional derivative systems and applied to second generation CRONE control, the robustness was also studied. CRONE (the French acronym of C ommande Robuste d'Ordre Non Entier ) control system design is a frequency-domain based methodology using complex fractional integration.

    Full Text Available Although positive incentives for cooperators and/or negative incentives for free-riders in social dilemmas play an important role in maintaining cooperation, there is still the outstanding issue of who should pay the cost of incentives. The second-order free-rider problem, in which players who do not provide the incentives dominate in a game, is a well-known academic challenge. In order to meet this challenge, we devise and analyze a meta-incentive game that integrates positive incentives (rewards and negative incentives (punishments with second-order incentives, which are incentives for other players' incentives. The critical assumption of our model is that players who tend to provide incentives to other players for their cooperative or non-cooperative behavior also tend to provide incentives to their incentive behaviors. In this paper, we solve the replicator dynamics for a simple version of the game and analytically categorize the game types into four groups. We find that the second-order free-rider problem is completely resolved without any third-order or higher (meta incentive under the assumption. To do so, a second-order costly incentive, which is given individually (peer-to-peer after playing donation games, is needed. The paper concludes that (1 second-order incentives for first-order reward are necessary for cooperative regimes, (2 a system without first-order rewards cannot maintain a cooperative regime, (3 a system with first-order rewards and no incentives for rewards is the worst because it never reaches cooperation, and (4 a system with rewards for incentives is more likely to be a cooperative regime than a system with punishments for incentives when the cost-effect ratio of incentives is sufficiently large. This solution is general and strong in the sense that the game does not need any centralized institution or proactive system for incentives.

    Full Text Available This paper covers the question if and how incentive schemes work evaluated by their impact on company performance (market capitalization and profit before tax. Based on a unique data set for German executive directors of DAX companies it can be proved that neither short (STI nor long term incentives (LTI plans necessarily support the company success. It rather depends on the efficiency of each plan, i. e. on its design. Special attention has to be paid on target setting. Short term focused objectives often miss their targets, whereas long term oriented objectives significantly support the company success. To solve the prisoner’s dilemma between employers and employees by a quasi-endless game, additional measures may be helpful, such as share ownership guidelines.

    This paper models the impact of extrinsic incentives in a tax compliance model. It also provides experimental evidence that confirms the existence of a positive relationship between rewards and tax compliance. If individuals are audited, rewards for honest taxpayers are effective in increasing the level of tax compliance. These results are particularly relevant in countries where there is little respect for tax law since rewards can contribute to crowding in the intrinsic motivation to comply.

  10. Measuring Provider Performance for Physicians Participating in the Merit-Based Incentive Payment System.

    Squitieri, Lee; Chung, Kevin C

    2017-07-01

    In 2017, the Centers for Medicare and Medicaid Services began requiring all eligible providers to participate in the Quality Payment Program or face financial reimbursement penalty. The Quality Payment Program outlines two paths for provider participation: the Merit-Based Incentive Payment System and Advanced Alternative Payment Models. For the first performance period beginning in January of 2017, the Centers for Medicare and Medicaid Services estimates that approximately 83 to 90 percent of eligible providers will not qualify for participation in an Advanced Alternative Payment Model and therefore must participate in the Merit-Based Incentive Payment System program. The Merit-Based Incentive Payment System path replaces existing quality-reporting programs and adds several new measures to evaluate providers using four categories of data: (1) quality, (2) cost/resource use, (3) improvement activities, and (4) advancing care information. These categories will be combined to calculate a weighted composite score for each provider or provider group. Composite Merit-Based Incentive Payment System scores based on 2017 performance data will be used to adjust reimbursed payment in 2019. In this article, the authors provide relevant background for understanding value-based provider performance measurement. The authors also discuss Merit-Based Incentive Payment System reporting requirements and scoring methodology to provide plastic surgeons with the necessary information to critically evaluate their own practice capabilities in the context of current performance metrics under the Quality Payment Program.

  11. Coarse-grained representation of the quasi adiabatic propagator path integral for the treatment of non-Markovian long-time bath memory

    Richter, Martin; Fingerhut, Benjamin P.

    2017-06-01

    The description of non-Markovian effects imposed by low frequency bath modes poses a persistent challenge for path integral based approaches like the iterative quasi-adiabatic propagator path integral (iQUAPI) method. We present a novel approximate method, termed mask assisted coarse graining of influence coefficients (MACGIC)-iQUAPI, that offers appealing computational savings due to substantial reduction of considered path segments for propagation. The method relies on an efficient path segment merging procedure via an intermediate coarse grained representation of Feynman-Vernon influence coefficients that exploits physical properties of system decoherence. The MACGIC-iQUAPI method allows us to access the regime of biological significant long-time bath memory on the order of hundred propagation time steps while retaining convergence to iQUAPI results. Numerical performance is demonstrated for a set of benchmark problems that cover bath assisted long range electron transfer, the transition from coherent to incoherent dynamics in a prototypical molecular dimer and excitation energy transfer in a 24-state model of the Fenna-Matthews-Olson trimer complex where in all cases excellent agreement with numerically exact reference data is obtained.

  12. Incentives for reporting disease outbreaks.

    Directory of Open Access Journals (Sweden)

    Ramanan Laxminarayan

    Full Text Available BACKGROUND: Countries face conflicting incentives to report infectious disease outbreaks. Reports of outbreaks can prompt other countries to impose trade and travel restrictions, which has the potential to discourage reporting. However, reports can also bring medical assistance to contain the outbreak, including access to vaccines. METHODS: We compiled data on reports of meningococcal meningitis to the World Health Organization (WHO from 54 African countries between 1966 and 2002, a period is marked by two events: first, a large outbreak reported from many countries in 1987 associated with the Hajj that resulted in more stringent requirements for meningitis vaccination among pilgrims; and second, another large outbreak in Sub-Saharan Africa in 1996 that led to a new international mechanism to supply vaccines to countries reporting a meningitis outbreak. We used fixed-effects regression modeling to statistically estimate the effect of external forcing events on the number of countries reporting cases of meningitis to WHO. FINDINGS: We find that the Hajj vaccination requirements started in 1988 were associated with reduced reporting, especially among countries with relatively fewer cases reported between 1966 and 1979. After the vaccine provision mechanism was in place in 1996, reporting among countries that had previously not reported meningitis outbreaks increased. INTERPRETATION: These results indicate that countries may respond to changing incentives to report outbreaks when they can do so. In the long term, these incentives are likely to be more important than surveillance assistance in prompt reporting of outbreaks.

    1985-01-01

    A uniform description of various path-dependent functions is presented with the help of expansion of the type of the Taylor series. So called ''path-integrals'' and ''path-tensor'' are introduced which are systems of many-component quantities whose values are defined for arbitrary paths in coordinated region of space in such a way that they contain a complete information on the path. These constructions are considered as elementary path-dependent functions and are used instead of power monomials in the usual Taylor series. Coefficients of such an expansion are interpreted as partial derivatives dependent on the order of the differentiations or else as nonstandard cavariant derivatives called two-point derivatives. Some examples of pathdependent functions are presented.Space curvature tensor is considered whose geometrica properties are determined by the (non-transitive) translator of parallel transport of a general type. Covariant operation leading to the ''extension'' of tensor fiels is pointed out

  4. Water Conservation and Economic Incentives

    2016-12-01

    Water has played a vital role in the progress of human civilization throughout history. Both agriculture based economics as well as industry based economics totally rely upon water for survival and prosperity. Water could be a limiting factor in dictating day-to-day human activities and as such one should learn to live within the limits of available natural resources. Most of the water on this earth is either salty or undrinkable. Only one percent of world's water is available for all the needs of human civilization. This includes human personal household needs, community activities, agriculture, industry, plant and animal life sustenance. The supply of usable fresh water is finite and the per capita consumption of fresh water needs to be reduced in particularly in some selected regions of this world. The United States consumes about 450 billion gallons of water every day. The U.S. daily average of water pumped by public water supply systems is 185 gallons per person. The biggest water gobbler in a household is the lawn. Typically, at least 50% of water consumed by households is used outdoors. Even inside a house, bathroom facilities claim nearly 75% of the water used. Here is a short list of economic Incentives that may help water conservation. (1) Providing rebates, refunds or other economic incentives to those consumers that are willing to change to modern technological methods. Examples include, but not limited to energy efficient washing machines, low-flush toilets and improved shower head designs. (2) Communities should provide economic incentives to limit the type and size of landscaping. (3) Need, necessity and nature of outdoor water use could be restricted whenever possible. (4) Sprinkler ban may be deemed appropriate in extreme cases. (5) Set up hotlines that can help penalize those that ignore water conservation guidelines. (6) Incorporating water conservation monitors. References: http://www.nrdc.org/water/http://www.ecy.wa.gov/programs/wr/ws/wtrcnsv.htmlhttp://www.sscwd.org/tips.html

  5. Asymmetrically dominated choice problems, the isolation hypothesis and random incentive mechanisms.

    Directory of Open Access Journals (Sweden)

    James C Cox

    Full Text Available This paper presents an experimental study of the random incentive mechanisms which are a standard procedure in economic and psychological experiments. Random incentive mechanisms have several advantages but are incentive-compatible only if responses to the single tasks are independent. This is true if either the independence axiom of expected utility theory or the isolation hypothesis of prospect theory holds. We present a simple test of this in the context of choice under risk. In the baseline (one task treatment we observe risk behavior in a given choice problem. We show that by integrating a second, asymmetrically dominated choice problem in a random incentive mechanism risk behavior can be manipulated systematically. This implies that the isolation hypothesis is violated and the random incentive mechanism does not elicit true preferences in our example.

Random incentive mechanisms have several advantages but are incentive-compatible only if responses to the single tasks are independent. This is true if either the independence axiom of expected utility theory or the isolation hypothesis of prospect theory holds. We present a simple test of this in the context of choice under risk. In the baseline (one task) treatment we observe risk behavior in a given choice problem. We show that by integrating a second, asymmetrically dominated choice problem in a random incentive mechanism risk behavior can be manipulated systematically. This implies that the isolation hypothesis is violated and the random incentive mechanism does not elicit true preferences in our example.

    In a Fisher market, a market maker sells m items to n potential buyers. The buyers submit their utility functions and money endowments to the market maker, who, upon receiving submitted information, derives market equilibrium prices and allocations of its items. While agents may benefit...... by misreporting their private information, we show that the percentage of improvement by a unilateral strategic play, called incentive ratio, is rather limited—it is less than 2 for linear markets and at most $e^{1/e}\\thickapprox 1.445$ for Cobb-Douglas markets. We further prove that both ratios are tight....

  8. Incentives for improvement of CANDU

    CANDU is a relatively young technology which has demonstrated many achievements as an electrical power generation system. These achievements include an unsurpassed safety record, high annual and lifetime capacity factors, low electricity cost and a broad range of other performance strengths which together indicate that the CANDU technology is fundamentally sound. Known capabilities not yet fully exploited, such as advanced fuel cycle options, indicate that CANDU technology will continue to pay strong dividends on research, development and design investment. This provides a strong incentive for the improvement of CANDU on a continuing basis

    I study the impact of the Orphan Drug Act (ODA), which established tax incentives for rare disease drug development. I examine the flow of new clinical drug trials for a large set of rare diseases. Among more prevalent rare diseases, the ODA led to a significant and sustained increase in new trials. The impact for less prevalent rare diseases was limited to an increase in the stock of drugs. Tax credits can stimulate R & D; yet because they leave revenue margins unaffected, tax credits appear to have a more limited impact on private innovation in markets with smaller revenue potential.

    The author analyses delegation in homogenous duopoly under the assumption that the firm-managers compete in supply functions. In supply function equilibrium, managers’ decisions are strategic complements. This reverses earlier findings in that the author finds that owners give managers incentives...... to act in an accommodating way. As a result, optimal delegation reduces per-firm output and increases profits to above-Cournot profits. Moreover, in supply function equilibrium the mode of competition is endogenous. This means that the author avoids results that are sensitive with respect to assuming...

    Osmundsen, Petter; Aven, Terje; Tomasgard, Asgeir

    2010-01-01

    Assurance of supply is a crucial objective for producers and consumers of oil and gas. A basic requirement to meet this objective is that producers and transmitters have sufficient economic incentives and capabilities to assure a desired degree of supply. The topic of this paper is to evaluate these incentives from a broad perspective. We examine economic trade-offs inherent in a delay of production, including reputational issues, as well as contract incentives for gas sellers, drilling companies, and oil service companies.

  19. Sustainable Groundwater Management Using Economic Incentive Approach

    Science.gov (United States)

    Yan, T.; Shih, J.; Sanchirico, J. N.

    2006-12-01

    Although groundwater accounts for about 20% of the water consumption in the US, recent urban development, land use changes and agricultural activities in many regions (for example, Chesapeake Bay and eastern shore of Maryland) have resulted in deleterious impacts on groundwater quality. These impacts have dramatically increased potential human health and ecological system risks. One example is nitrogen pollution delivered to local waterways from septic systems via groundwater. Conventional approaches for nitrogen removal, such as pumping and treatment (nitrification-denitrification) process, tend to be expensive. On the other hand, economic incentive approaches (such as marketable permits) have the potential to increase the efficiency of environmental policy by reducing compliance costs for regulated entities and individuals and/or achieving otherwise uneconomical pollution reduction. The success of the sulfur dioxide trading market has led to the creation of trading markets for other pollutants, especially at the regional, state, and smaller (e.g. watershed) scales. In this paper, we develop an integrated framework, which includes a groundwater flow and transport model, and a conceptual management model. We apply this framework to a synthetic set up which includes one farm and two development areas in order to investigate the potential of using economic incentive approaches for groundwater quality management. The policy analysis is carried out by setting up the objective of the modeling framework to minimize the total cost of achieving groundwater quality goals at specific observation point using either a transferable development right (TDR) system between development areas and/or using a tax for fertilizer usage in the farm area. The TDR system consists of a planning agency delineating a region into restricted-use (e.g., agriculture, open space) and high intensity zones (e.g., residential, commercial uses). The agency then endows landowners in the restricted area

    1983-01-01

    Much is expected of path integration as a quantization procedure. Much more is possible if one recognizes that path integration is at the crossroad of stochastic and differential calculus and uses the full power of both stochastic and differential calculus in setting up and computing path integrals. In contrast to differential calculus, stochastic calculus has only comparatively recently become an instrument of thought. It has nevertheless already been used in a variety of challenging problems, for instance in the quantization problem. The author presents some applications of the stochastic scheme. (Auth.)

    Paths on the R 3 real Euclidean manifold are defined as 2-dimensional simplicial strips which are orbits of the action of a discrete one-parameter group. It is proven that there exists at least one embedding of R 3 in the free Z-module generated by S 2 (x 0 ). The speed is defined as the simplicial derivative of the path. If mass is attached to the simplex, the free Lagrangian is proportional to the width of the path. In the continuum limit, the relativistic form of the Lagrangian is recovered. (author). 7 refs

    Pavlickova, Hana; Bremner, Stephen A; Priebe, Stefan

    2015-08-01

    A recent cluster-randomized controlled trial found that offering financial incentives improves adherence to long-acting injectable antipsychotics (LAIs). The present study investigates whether the impact of incentives diminishes over time and whether the improvement in adherence is linked to the amount of incentives offered. Seventy-three teams with 141 patients with psychotic disorders (using ICD-10) were randomized to the intervention or control group. Over 1 year, patients in the intervention group received £15 (US $23) for each LAI, while control patients received treatment as usual. Adherence levels, ie, the percentage of prescribed LAIs that were received, were calculated for quarterly intervals. The amount of incentives offered was calculated from the treatment cycle at baseline. Multilevel models were used to examine the time course of the effect of incentives and the effect of the amount of incentives offered on adherence. Adherence increased in both the intervention and the control group over time by an average of 4.2% per quarterly interval (95% CI, 2.8%-5.6%; P time and treatment group. Further, a higher total amount of incentives was associated with poorer adherence (βbootstrapped = -0.11; 95% CIbootstrapped, -0.20 to -0.01; P = .023). A substantial effect of financial incentives on adherence to LAIs occurs within the first 3 months of the intervention and is sustained over 1 year. A higher total amount of incentives does not increase the effect. ISRCTN.com identifier: ISRCTN77769281 and UKCRN.org identifier: 7033. © Copyright 2015 Physicians Postgraduate Press, Inc.

The interaction of the magnitude of a reward with its delay is confirmed, and the causes and implications of this interaction are discussed.

  11. Incentive contracts for development projects

    Science.gov (United States)

    Finley, David T.; Smith, Byron; DeGroff, B.

    2012-09-01

    Finding a contract vehicle that balances the concerns of the customer and the contractor in a development project can be difficult. The customer wants a low price and an early delivery, with as few surprises as possible as the project progresses. The contractor wants sufficient cost and schedule to cover risk. Both want to clearly define what each party will provide. Many program offices do not want to award cost plus contracts because their funding sources will not allow it, their boards do not want an open ended commitment, and they feel like they lose financial control of the project. A fixed price incentive contract, with a mutually agreed upon target cost, provides the owner with visibility into the project and input into the execution of the project, encourages both parties to save costs, and stimulates a collaborative atmosphere by aligning the respective interests of customers and contractors.

    2005-01-01

    This paper analyses the relation between end-users energy attitudes and their corresponding energy behaviour. It presents empirical findings from analyses of the effects of two-way communication between consumers and power companies. Two-way communication has made available high quality data on energy consumption. In the build-up to the analysis in this paper the a number of aspects thought to influence energy consumption has been looked at; including standard of housing, number and age of residents, as well as socio-economic factors, behaviour and preferences. Here we choose to focus specifically on attitudes and behaviour. These aspects are controlled for price incentives. The combination of very tight peak power balance in the Nordic power system and few investments in extension of power networks has turned the focus towards manual or automatic demand-response which requires hourly metering for documentation. The data are two-fold: Hourly recordings of meter-data of electric consumption of 10,894 customers (nearly half of these had installed technology for remote load control) in two different network areas and survey-data from a questionnaire distributed to consumers that resulted in nearly 550 answers. During the winter 2003/2004 these customers were offered different price incentives. The analyses showed a net reduction in electricity consumption of 1,0 kWh/h at the most in peak load hours. The paper is based on two connected studies, 'End-user flexibility by efficient use of ICT' and 'Improving end-user knowledge for managing energy loads end consumption' conducted in Norway by the SINTEF group

  15. Path Integrals in Quantum Mechanics

    International Nuclear Information System (INIS)

    Chetouani, L

    2005-01-01

    By treating path integrals the author, in this book, places at the disposal of the reader a modern tool for the comprehension of standard quantum mechanics. Thus the most important applications, such as the tunnel effect, the diffusion matrix, etc, are presented from an original point of view on the action S of classical mechanics while having it play a central role in quantum mechanics. What also emerges is that the path integral describes these applications more richly than are described traditionally by differential equations, and consequently explains them more fully. The book is certainly of high quality in all aspects: original in presentation, rigorous in the demonstrations, judicious in the choice of exercises and, finally, modern, for example in the treatment of the tunnel effect by the method of instantons. Moreover, the correspondence that exists between classical and quantum mechanics is well underlined. I thus highly recommend this book (the French version being already available) to those who wish to familiarize themselves with formulation by path integrals. They will find, in addition, interesting topics suitable for exploring further. (book review)

    2015-09-15

    Both the Jones and Mueller matrices encounter difficulties when physically modeling mixed materials or rough surfaces due to the complexity of light-matter interactions. To address these issues, we derived a matrix called the paths correlation matrix (PCM), which is a probabilistic mixture of Jones matrices of every light propagation path. Because PCM is related to actual light propagation paths, it is well suited for physical modeling. Experiments were performed, and the reflection PCM of a mixture of polypropylene and graphite was measured. The PCM of the mixed sample was accurately decomposed into pure polypropylene's single reflection, pure graphite's single reflection, and depolarization caused by multiple reflections, which is consistent with the theoretical derivation. Reflection parameters of rough surface can be calculated from PCM decomposition, and the results fit well with the theoretical calculations provided by the Fresnel equations. These theoretical and experimental analyses verify that PCM is an efficient way to physically model light-matter interactions.

  1. Determinants of investment under incentive regulation: The case of the Norwegian electricity distribution networks

    International Nuclear Information System (INIS)

    Poudineh, Rahmatallah; Jamasb, Tooraj

    2016-01-01

    Investment in electricity networks, as regulated natural monopolies, is among the highest regulatory and energy policy priorities. The electricity sector regulators adopt different incentive mechanisms to ensure that the firms undertake sufficient investment to maintain and modernise the grid. Thus, an effective regulatory treatment of investment requires understanding the response of companies to the regulatory incentives. This study analyses the determinants of investment in electricity distribution networks using a panel dataset of 129 Norwegian companies observed from 2004 to 2010. A Bayesian Model Averaging approach is used to provide a robust statistical inference by taking into account the uncertainties around model selection and estimation. The results show that three factors drive nearly all network investments: investment rate in previous period, socio-economic costs of energy not supplied and finally useful life of assets. The results indicate that Norwegian companies have, to some degree, responded to the investment incentives provided by the regulatory framework. However, some of the incentives do not appear to be effective in driving the investments. - Highlights: • This paper investigates determinants of investment under incentive regulation. • We apply a Bayesian model averaging technique to deal with model uncertainty. • Dataset comprises 129 Norwegian electricity network companies from 2004 to 2010. • The results show that firms have generally responded to investment incentives. • However, some of the incentives do not appear to have been effective.

    Full Text Available The incentives of health care expenditure (HCE have been a topic of discussion in the USA (Obama reforms and in Europe (adjustment to debt crisis. There are competing views of institutional versus GDP (unit income elasticity and productivity related factors of growth of expenditure. However ageing of populations, technology change and economic incentives related to institutions are also key drivers of growth according to the OECD and EU’s AWG committee. Simulation models have been developed to forecast the growth of social expenditure (including HCEs to 2050. In this article we take a historical perspective to look at the institutional structures and their relationship to HCE growth. When controlling for age structure, price developments, doctor density and in-patient and public shares of expenditures, we find that fee-for-service in primary care, is according to the results, in at least 20 percent more costly than capitation or salary remuneration. Capitation and salary (or wage remuneration are at same cost levels in primary care. However we did not find the cost lowering effect for gatekeeping which could have been expected based on previous literature. Global budgeting 30 (partly DRG based percent less costly in specialized care than other reimbursement schemes like open contracting or volume based reimbursement. However the public integration of purchaser and provider cost seems to result to about 20 higher than public reimbursement or public contracting. Increasing the number of doctors or public financing share results in increased HCEs. Therefore expanding public reimbursement share of health services seems to lead to higher HCE. On the contrary, the in-patient share reduced expenditures. Compared to the previous literature, the finding on institutional dummies is in line with similar modeling papers. However the results for public expansion of services is a contrary one to previous works on the subject. The median lag length of

  6. Classical and quantum dynamics from classical paths to path integrals

    CERN Document Server

    Dittrich, Walter

    2017-01-01

    Graduate students who wish to become familiar with advanced computational strategies in classical and quantum dynamics will find in this book both the fundamentals of a standard course and a detailed treatment of the time-dependent oscillator, Chern-Simons mechanics, the Maslov anomaly and the Berry phase, to name just a few topics. Well-chosen and detailed examples illustrate perturbation theory, canonical transformations and the action principle, and demonstrate the usage of path integrals. The fifth edition has been revised and enlarged to include chapters on quantum electrodynamics, in particular, Schwinger’s proper time method and the treatment of classical and quantum mechanics with Lie brackets and pseudocanonical transformations. It is shown that operator quantum electrodynamics can be equivalently described with c-numbers, as demonstrated by calculating the propagation function for an electron in a prescribed classical electromagnetic field.

  7. MEASURING PATH DEPENDENCY

    Directory of Open Access Journals (Sweden)

    Peter Juhasz

    2017-03-01

    Full Text Available While risk management gained popularity during the last decades even some of the basic risk types are still far out of focus. One of these is path dependency that refers to the uncertainty of how we reach a certain level of total performance over time. While decision makers are careful in accessing how their position will look like the end of certain periods, little attention is given how they will get there through the period. The uncertainty of how a process will develop across a shorter period of time is often “eliminated” by simply choosing a longer planning time interval, what makes path dependency is one of the most often overlooked business risk types. After reviewing the origin of the problem we propose and compare seven risk measures to access path. Traditional risk measures like standard deviation of sub period cash flows fail to capture this risk type. We conclude that in most cases considering the distribution of the expected cash flow effect caused by the path dependency may offer the best method, but we may need to use several measures at the same time to include all the optimisation limits of the given firm

  9. Countervailing incentives in value-based payment.

    Science.gov (United States)

    Arnold, Daniel R

    2017-09-01

    Payment reform has been at the forefront of the movement toward higher-value care in the U.S. health care system. A common belief is that volume-based incentives embedded in fee-for-service need to be replaced with value-based payments. While this belief is well-intended, value-based payment also contains perverse incentives. In particular, behavioral economists have identified several features of individual decision making that reverse some of the typical recommendations for inducing desirable behavior through financial incentives. This paper discusses the countervailing incentives associated with four behavioral economic concepts: loss aversion, relative social ranking, inertia or status quo bias, and extrinsic vs. intrinsic motivation.

    This paper studies the effects of peer pressure on incentives. We assume that, in addition to the material payoff, each agent's utility includes the psychological payoff from peer pressure generated by a comparison of effort costs. We show that the optimal incentive schemes depend mainly on the degree of peer pressure and of the heterogeneity of agents. Furthermore, we examine the optimal organizational forms in terms of the principal''s intention to make use of the effects of peer pressure.

    This article demonstrates that the position of dominance enjoyed by state sanitation companies dictates the public policy decision-making process for sanitation in Brazil. These companies' hegemony is explained here through the analysis of a path that generated political and economic incentives that have permitted its consolidation over time. Through the content analysis of the legislation proposed for the sector and the material produced by the stakeholders involved in the approval of new regulations for the sector in 2007, the study identifies the main sources of incentive introduced by the adoption of the National Sanitation Plan, which explain certain structural features of the current sanitation policy and its strong capacity to withstand the innovations proposed under democratic rule.

    2013-01-01

    To improve prognosis in recurrent glioblastoma we developed a treatment protocol based on a combination of drugs not traditionally thought of as cytotoxic chemotherapy agents but that have a robust history of being well-tolerated and are already marketed and used for other non-cancer indications. Focus was on adding drugs which met these criteria: a) were pharmacologically well characterized, b) had low likelihood of adding to patient side effect burden, c) had evidence for interfering with a recognized, well-characterized growth promoting element of glioblastoma, and d) were coordinated, as an ensemble had reasonable likelihood of concerted activity against key biological features of glioblastoma growth. We found nine drugs meeting these criteria and propose adding them to continuous low dose temozolomide, a currently accepted treatment for relapsed glioblastoma, in patients with recurrent disease after primary treatment with the Stupp Protocol. The nine adjuvant drug regimen, Coordinated Undermining of Survival Paths, CUSP9, then are aprepitant, artesunate, auranofin, captopril, copper gluconate, disulfiram, ketoconazole, nelfinavir, sertraline, to be added to continuous low dose temozolomide. We discuss each drug in turn and the specific rationale for use- how each drug is expected to retard glioblastoma growth and undermine glioblastoma's compensatory mechanisms engaged during temozolomide treatment. The risks of pharmacological interactions and why we believe this drug mix will increase both quality of life and overall survival are reviewed. PMID:23594434

  1. Incentive-compatible guaranteed renewable health insurance premiums.

    Science.gov (United States)

    Herring, Bradley; Pauly, Mark V

    2006-05-01

    Theoretical models of guaranteed renewable insurance display front-loaded premium schedules. Such schedules both cover lifetime total claims of low-risk and high-risk individuals and provide an incentive for those who remain low-risk to continue to purchase the policy. Questions have been raised of whether actual individual insurance markets in the US approximate the behavior predicted by these models, both because young consumers may not be able to "afford" front-loading and because insurers may behave strategically in ways that erode the value of protection against risk reclassification. In this paper, the optimal competitive age-based premium schedule for a benchmark guaranteed renewable health insurance policy is estimated using medical expenditure data. Several factors are shown to reduce the amount of front-loading necessary. Indeed, the resulting optimal premium path increases with age. Actual premium paths exhibited by purchasers of individual insurance are close to the optimal renewable schedule we estimate. Finally, consumer utility associated with the feature is examined.

    2016-01-01

    Pneumothorax is the presence of air in the pleural space. Its management consists of noninvasive and invasive therapies and it is determined based on clinical manifestations, type and size of pneumothorax. We present a case of a patient with diagnosis of primary spontaneous pneumothorax treated with incentive spirometry (noninvasive therapy). A 20 year old man came to respirology clinic with chief complaint of shortness of breath. He was recently diagnosed with left pneumothorax based on previous chest X-ray in another health care facilities and was advised to undergo tube thoracostomy but he refused the procedure. On physical examination, vital signs were normal. Chest X-ray showed 33% of pneumothorax or 1.2 cm. He was asked to perform incentive spirometry therapy at home. During 12 days of therapy, shortness of breath slowly disappeared and on repeated chest X-ray, it showed minimal pneumothorax in the left upper hemithorax. Noninvasive treatment such as incentive spirometry can be considered in patient with minimal symptoms and no signs of life-threatening respiratory distress.

  3. Survey of state approaches to solar energy incentives

    Energy Technology Data Exchange (ETDEWEB)

    Johnson, S. B.

    1979-07-01

    A comprehensive survey is presented of state statutes designed to encourage the application of solar technology. A large majority of the states have enacted financial incentives designed to stimulate solar energy use. Commonly, these incentives include preferential property tax treatment of solar systems, and income tax benefits to solar users. There are a wide variety of other tax breaks as well, including excise and franchise tax incentives. Some states have recently developed loan or grant programs for solar installations. Other states have addressed aspects of real property and land-use planning law, which have served as barriers to either the installation of solar technology or access to sunlight. In addition to removing such obstacles as restrictive convenants and zoning limitations, the legislation of several states provides affirmative recognition of the potential of real property law to serve as a spur to solar development, through solar easements, planning and zoning, and public nuisance. A small number of states have legislated in the field of utility regulation, addressing important questions of (1) nondiscriminatory rates for utility backup to solar systems and public utility commissions, and (2) utility involvement in solar energy applicatons.

  4. Nonadiabatic transition path sampling

    International Nuclear Information System (INIS)

    Sherman, M. C.; Corcelli, S. A.

    2016-01-01

    Fewest-switches surface hopping (FSSH) is combined with transition path sampling (TPS) to produce a new method called nonadiabatic path sampling (NAPS). The NAPS method is validated on a model electron transfer system coupled to a Langevin bath. Numerically exact rate constants are computed using the reactive flux (RF) method over a broad range of solvent frictions that span from the energy diffusion (low friction) regime to the spatial diffusion (high friction) regime. The NAPS method is shown to quantitatively reproduce the RF benchmark rate constants over the full range of solvent friction. Integrating FSSH within the TPS framework expands the applicability of both approaches and creates a new method that will be helpful in determining detailed mechanisms for nonadiabatic reactions in the condensed-phase.

    A preliminary evaluation capability for two-dimensional groundwater pollution problems was developed as part of the Transport Modeling Task for the Waste Isolation Safety Assessment Program (WISAP). Our approach was to use the data limitations as a guide in setting the level of modeling detail. PATHS Groundwater Hydrologic Model is the first level (simplest) idealized hybrid analytical/numerical model for two-dimensional, saturated groundwater flow and single component transport; homogeneous geology. This document consists of the description of the PATHS groundwater hydrologic model. The preliminary evaluation capability prepared for WISAP, including the enhancements that were made because of the authors' experience using the earlier capability is described. Appendixes A through D supplement the report as follows: complete derivations of the background equations are provided in Appendix A. Appendix B is a comprehensive set of instructions for users of PATHS. It is written for users who have little or no experience with computers. Appendix C is for the programmer. It contains information on how input parameters are passed between programs in the system. It also contains program listings and test case listing. Appendix D is a definition of terms.

    We present a brief overview of the incentive sensitization theory of addiction. This posits that addiction is caused primarily by drug-induced sensitization in the brain mesocorticolimbic systems that attribute incentive salience to reward-associated stimuli. If rendered hypersensitive, these systems cause pathological incentive motivation (‘wanting’) for drugs. We address some current questions including: what is the role of learning in incentive sensitization and addiction? Does incentive s...

    Full Text Available OBJECTIVE: We explored whether financial incentives have a role in patients' decisions to accept (purchase a continuous positive airway pressure (CPAP device in a healthcare system that requires cost sharing. DESIGN: Longitudinal interventional study. PATIENTS: The group receiving financial incentive (n = 137, 50.8±10.6 years, apnea/hypopnea index (AHI 38.7±19.9 events/hr and the control group (n = 121, 50.9±10.3 years, AHI 39.9±22 underwent attendant titration and a two-week adaptation to CPAP. Patients in the control group had a co-payment of $330-660; the financial incentive group paid a subsidized price of $55. RESULTS: CPAP acceptance was 43% greater (p = 0.02 in the financial incentive group. CPAP acceptance among the low socioeconomic strata (n = 113 (adjusting for age, gender, BMI, tobacco smoking was enhanced by financial incentive (OR, 95% CI (3.43, 1.09-10.85, age (1.1, 1.03-1.17, AHI (>30 vs. 30 vs. 30 vs. <30 (5.25, 1.34-18.5. CONCLUSIONS: Minimizing cost sharing reduces a barrier for CPAP acceptance among low socioeconomic status patients. Thus, financial incentive should be applied as a policy to encourage CPAP treatment, especially among low socioeconomic strata patients.

    2008-08-01

    Working memory is one of several putative core neurocognitive processes in attention-deficit/hyperactivity disorder (ADHD). The present work seeks to determine whether visual-spatial working memory is sensitive to motivational incentives, a laboratory analogue of behavioral treatment. Participants were 21 children (ages 7-10) with a diagnosis of ADHD-combined type. Participants completed a computerized spatial span task designed to assess storage of visual-spatial information (forward span) and manipulation of the stored information (backward span). The spatial span task was completed twice on the same day, once with a performance-based incentive (trial-wise feedback and points redeemable for prizes) and once without incentives. Participants performed significantly better on the backward span when rewarded for correct responses, compared to the no incentive condition. However, incentives had no effect on performance during the forward span. These findings may suggest the use of motivational incentives improved manipulation, but not storage, of visual-spatial information among children with ADHD. Possible explanations for the differential incentive effects are discussed, including the possibility that incentives prevented a vigilance decrement as task difficulty and time on task increased.

    Science.gov (United States)

    Berdud, Mikel; Cabasés, Juan M; Nieto, Jorge

    It has been established in the literature that workers within public organisations are intrinsically motivated. This paper is an empirical study of the healthcare sector using methods of qualitative analysis research, which aims to answer the following hypotheses: 1) doctors are intrinsically motivated; 2) economic incentives and control policies may undermine doctors' intrinsic motivation; and 3) well-designed incentives may encourage doctors' intrinsic motivation. We conducted semi-structured interviews à-la-Bewley with 16 doctors from Navarre's Healthcare Service (Servicio Navarro de Salud-Osasunbidea), Spain. The questions were based on current theories of intrinsic motivation and incentives to test the hypotheses. Interviewees were allowed to respond openly without time constraints. Relevant information was selected, quantified and analysed by using the qualitative concepts of saturation and codification. The results seem to confirm the hypotheses. Evidence supporting hypotheses 1 and 2 was gathered from all interviewees, as well as indications of the validity of hypothesis 3 based on interviewees' proposals of incentives. The conclusions could act as a guide to support the optimal design of incentive policies and schemes within health organisations when healthcare professionals are intrinsically motivated.

    Full Text Available In order to invest there are some incentives needed, including among them, certainly, the ones discussed and analysed in the scientific literature such as: specific earning chances (expectations of each participant (wage, profit, dividend, budget revenue, etc., potential investor’s general or current state, etc.. Less visible incentives from complex areas not obviously related to the investment are, however, less considered. Among these could be incentives arising from inherited or education and culture transmitted philosophy, generally regarding earnings, business and investment. We notice these incentives in case of FDI in different shades and intensities.Investor’s decision to acquire, sell or to carry out projects in a particular area, region or country is not only due to purely economic, commercial or financial reasoning. In such operations, meeting among businessmen, managers and other professionals in the field is, first of all, meeting in specific circumstances, among more or less different cultures.Both theory and practice must be concerned in what way and to what extent these factors influence the investment intention, outcome and yield. Our study proposes a list of the most important cultural type incentives for investment (mainly FDI, based on a set of cases, through a logical and empirical research, using some of the most relevant and recent studies and several real situations to which we got access. These are early data and analysis that will allow us to draw attention to the problem and to develop further research to reach generalizable results

    Problems related to consideration of operator nonpermutability in Hamiltonian path integral (HPI) are considered in the review. Integrals are investigated using trajectories in configuration space (nonrelativistic quantum mechanics). Problems related to trajectory integrals in HPI phase space are discussed: the problem of operator nonpermutability consideration (extra terms problem) and corresponding equivalence rules; ambiguity of HPI usual recording; transition to curvilinear coordinates. Problem of quantization of dynamical systems with couplings has been studied. As in the case of canonical transformations, quantization of the systems with couplings of the first kind requires the consideration of extra terms

    Within the Malaysian context, incentive system in scientific publishing rewards authors for publishing journal articles or conference papers that are indexed by Scopus. At Universiti Tun Hussein Onn Malaysia, the incentive system is going into its third year in operational. The main challenge lies in preparing the evidences as required by the application guideline. This paper presents an online module for publication incentive within the University Publication Information System (SMPU). The module was developed using the Scrum methodology based on the existing workflow of paper-based application. The module is hoped to increase the quality of the system deliverables of SMPU as well as having the ability to cope with change of university requirements in the future.

We reach to the conclusion that the cost-benefit relationship of the restoration process by itself can be straightforward calculated in some cases, calculating economic benefits accrued from the diversity restored to ecosystem is more difficult. In terms of the incentives for biodiversity restoration, we concluded that in many cases, economic variables out of the control of those involved in restoration are determinant.

  3. Generic host state incentive report. Draft

    International Nuclear Information System (INIS)

    1985-01-01

    Even the most carefully designed and operated low-level radioactive waste management facility will present potential risks and costs to nearby residents. Individuals who live near these facilities may receive some benefits, but they also bear the brunt of any adverse impacts. It is with this in mind that various siting techniques have been developed. Before any ''extra'' compensation or incentive can be discussed, however, it must first be clearly demonstrated that these facilities protect public health and the environment. This report addresses five distinct areas as follows: mitigation measure to prevent or reduce the impact of the facility; incentives and compensation techniques that might make a facility more acceptable; the use of agreement building in order to develop an arrangement between the host community and a facility proponent; the importance of economics resulting from a typical regional low-level radioactive waste facility; and the role of state government in promoting and legitimizing the use of incentives. 6 tabs

  4. Incentive relativity in middle aged rats.

    Response to a reinforcer is affected by prior experience with different reward values of that reward, a phenomenon known as incentive relativity. Two different procedures to study this phenomenon are the incentive downshift (ID) and the consummatory anticipatory negative contrast (cANC), the former is an emotional-cognitive protocol and the latter cognitive one. Aged rodents, as also well described in aged humans, exhibit alterations in cognitive functions. The main goal of this work was to evaluate the effect of age in the incentive' assessment using these two procedures. The results indicated that aged rats had an adequate assessment of the rewards but their performance is not completely comparable to that of young subjects. They recover faster from the ID and they had a cognitive impairment in the cANC. The results are discussed in relation to age-related changes in memory and emotion.

  5. The safety-incentive theory of liability

    International Nuclear Information System (INIS)

    Marshall, J.M.

    1977-11-01

    The use of liability law to improve incentives for safety is supported by certain recent theoretical results. The main ideas and the key argumants are summarized. Basic weaknesses of the theory are discussed, namely: (1) the simple model of Calabresi does not generalize; (2) the more complex systems of J.P. Brown, P. Diamond, and J. Green require that courts possess a great deal of information and use it to set appropriate standards of due care; (3) in practice safety incentives also depend upon fear of criminal penalties and the sense of social responsibility. The questions whether and when liability rules can significantly affect incentives are addressed. It is concluded that the theory in its present state can hardly serve as a basis for altering liability rules

  6. World nuclear energy paths

    International Nuclear Information System (INIS)

    Connolly, T.J.; Hansen, U.; Jaek, W.; Beckurts, K.H.

    1979-01-01

    In examing the world nuclear energy paths, the following assumptions were adopted: the world economy will grow somewhat more slowly than in the past, leading to reductions in electricity demand growth rates; national and international political impediments to the deployment of nuclear power will gradually disappear over the next few years; further development of nuclear power will proceed steadily, without serious interruption but with realistic lead times for the introduction of advanced technologies. Given these assumptions, this paper attempts a study of possible world nuclear energy developments, disaggregated on a regional and national basis. The scenario technique was used and a few alternative fuel-cycle scenarios were developed. Each is an internally consistent model of technically and economically feasible paths to the further development of nuclear power in an aggregate of individual countries and regions of the world. The main purpose of this modeling exercise was to gain some insight into the probable international locations of reactors and other nuclear facilities, the future requirements for uranium and for fuel-cycle services, and the problems of spent-fuel storage and waste management. The study also presents an assessment of the role that nuclear power might actually play in meeting future world energy demand

However, the optimal utilitarian policy......Tax distortions cause a trade-off between efficiency and equity. However, taxes not only affect incentives; they also provide implicit insurance, and this may critically affect the efficiency–equity relationship.

    OpenAIRE

    2013-01-01

    Incentives often distort behavior: they induce agents to exert effort but this effort is not employed optimally. This paper proposes a theory of incentive design allowing for such distorted behavior. At the heart of the theory is a trade-off between getting the agent to exert effort and ensuring that this effort is used well. The theory covers various moral-hazard models, ranging from traditional single-task to multi-task models. It also provides -for the first time- a formalization and proof...

  11. Differential dependence of Pavlovian incentive motivation and instrumental incentive learning processes on dopamine signaling

    2011-01-01

    Here we attempted to clarify the role of dopamine signaling in reward seeking. In Experiment 1, we assessed the effects of the dopamine D1/D2 receptor antagonist flupenthixol (0.5 mg/kg i.p.) on Pavlovian incentive motivation and found that flupenthixol blocked the ability of a conditioned stimulus to enhance both goal approach and instrumental performance (Pavlovian-to-instrumental transfer). In Experiment 2 we assessed the effects of flupenthixol on reward palatability during post-training noncontingent re-exposure to the sucrose reward in either a control 3-h or novel 23-h food-deprived state. Flupenthixol, although effective in blocking the Pavlovian goal approach, was without effect on palatability or the increase in reward palatability induced by the upshift in motivational state. This noncontingent re-exposure provided an opportunity for instrumental incentive learning, the process by which rats encode the value of a reward for use in updating reward-seeking actions. Flupenthixol administered prior to the instrumental incentive learning opportunity did not affect the increase in subsequent off-drug reward-seeking actions induced by that experience. These data suggest that although dopamine signaling is necessary for Pavlovian incentive motivation, it is not necessary for changes in reward experience, or for the instrumental incentive learning process that translates this experience into the incentive value used to drive reward-seeking actions, and provide further evidence that Pavlovian and instrumental incentive learning processes are dissociable.

  12. Creating New Economic Incentives for Repurposing Generic Drugs for Unsolved Diseases Using Social Finance.

    Science.gov (United States)

    Bloom, Bruce E

    2015-12-01

    Repurposing research improves patient lives by taking drugs approved for one disease and clinically testing them to create a treatment for a different disease. Repurposing drugs that are generic, inexpensive, and widely available and that can be taken in their current dosage and formulation in the new indication provide a quick, affordable, and effective way to create "new" treatments. However, generic drug repurposing often provides no profit potential, and so there is no economic incentive for industry to pursue this, and philanthropy and government funds are often insufficient. One way to create new economic incentive for the repurposing of generic drugs is through social finance. This perspective describes how social finance can create a new economic incentive by using a social impact bond, or similar financial structure, to repay for-profit investors who fund the repurposing research from the proceeds of healthcare cost reductions generated when these affordable, effective, and widely available repurposed therapies improve healthcare outcomes.

    Full Text Available A theory of cultural structures predicts the objects observed by anthropologists. We here define those which use kinship relationships to define systems. A finite structure we call a partially defined quasigroup (or pdq, as stated by Definition 1 below on a dictionary (called a natural language allows prediction of certain anthropological descriptions, using homomorphisms of pdqs onto finite groups. A viable history (defined using pdqs states how an individual in a population following such history may perform culturally allowed associations, which allows a viable history to continue to survive. The vector states on sets of viable histories identify demographic observables on descent sequences. Paths of vector states on sets of viable histories may determine which histories can exist empirically.

  14. Propagators and path integrals

    Energy Technology Data Exchange (ETDEWEB)

    Holten, J.W. van

    1995-08-22

    Path-integral expressions for one-particle propagators in scalar and fermionic field theories are derived, for arbitrary mass. This establishes a direct connection between field theory and specific classical point-particle models. The role of world-line reparametrization invariance of the classical action and the implementation of the corresponding BRST-symmetry in the quantum theory are discussed. The presence of classical world-line supersymmetry is shown to lead to an unwanted doubling of states for massive spin-1/2 particles. The origin of this phenomenon is traced to a `hidden` topological fermionic excitation. A different formulation of the pseudo-classical mechanics using a bosonic representation of {gamma}{sub 5} is shown to remove these extra states at the expense of losing manifest supersymmetry.

    Malaysians indicating that they did not intend to become organ donors upon their death were surveyed regarding interest in non-fungible financial incentives to be granted to surviving family members. Among the 730 (56% of the total sample of 1311) indicating unwillingness to be donors, 29.6% (216/730) subsequently indicated that they would be willing donors if the government introduced policies that, upon their death, "rewarded your (their) family with incentives for your (their) deeds." Among the 69% (504/730) who insisted that they would not become organ donor even with incentive, nearly 80% (404/501) of them were able to identify relevant incentives they thought should be provided by the state to those who make organ donations upon death. The majority of both groups preferred the state provide medical benefits to a surviving family member, suggesting this may be an attractive policy option for the state to raise the deceased organ donation pool. © 2013 John Wiley & Sons A/S.

    The objectives of this study were to explore RN perceptions regarding barriers/challenges and incentives/supports for BSN completion and identify recommendations to increase RN BSN completion. The Institute of Medicine's 2011 The Future of Nursing report recommended the proportion of RNs with a BSN increase to 80% by 2020. This qualitative study included 41 RNs who participated in 1 of 6 focus groups based on their BSN completion status. Primary themes were sacrifices, barriers/challenges, incentives/supports, value, how to begin, and pressure. Primary BSN completion barriers/challenges were work-life balance and economic issues. Incentives/supports identified were financial compensation, assistance from employer and academic institution, and encouragement from family. Institutional strategies recommended for increasing BSN completion rates were improved access to education and financial support facilitated by collaboration between hospitals and academic institutions. Exploring RN barriers/challenges and incentives/supports for BSN completion can lead to implementation of institutional strategies, such as tuition reimbursement and academic collaboration.

  5. Financial Incentives to Promote Active Travel

    Science.gov (United States)

    Martin, Adam; Suhrcke, Marc; Ogilvie, David

    2012-01-01

    Context Financial incentives, including taxes and subsidies, can be used to encourage behavior change. They are common in transport policy for tackling externalities associated with use of motor vehicles, and in public health for influencing alcohol consumption and smoking behaviors. Financial incentives also offer policymakers a compromise between “nudging,” which may be insufficient for changing habitual behavior, and regulations that restrict individual choice. Evidence acquisition The literature review identified studies published between January 1997 and January 2012 of financial incentives relating to any mode of travel in which the impact on active travel, physical activity, or obesity levels was reported. It encompassed macroenvironmental schemes, such as gasoline taxes, and microenvironmental schemes, such as employer-subsidized bicycles. Five relevant reviews and 20 primary studies (of which nine were not included in the reviews) were identified. Evidence synthesis The results show that more-robust evidence is required if policymakers are to maximize the health impact of fiscal policy relating to transport schemes of this kind. Conclusions Drawing on a literature review and insights from the SLOTH (sleep, leisure, occupation, transportation, and home-based activities) time-budget model, this paper argues that financial incentives may have a larger role in promoting walking and cycling than is acknowledged generally.

    Full Text Available No abstract available. Article truncated after 150 words. Health spending is a huge part of the United States economy as it is a large business. We all have seen increasing inclusion of corporate practices in health care. One such inclusion is the incentive programs which have at their core the goal of production of the desired behavioral outcomes directly related either to performance output or extraordinary achievement. However, management influence on the organization’s ethical environment and culture can inadvertently encourage or endorse unethical behavior despite the best intentions. One way would be failing to link performance incentives to ethical practice. When leaders create strong incentives to accomplish a goal without creating equally strong incentives to adhere to ethical practice in achieving the desired goal, they effectively set the stage for ethical malpractice. Incentivizing ethical practice is equally important as incentivizing other behaviors (1. In the health care industry, unlike in the sales industry, professionalism and patient care are …

    1983-01-01

    Limited anecdotal evidence from existing incentive-based facility sitings, and from a survey of rural Wisconsin residents in 1980 regarding the acceptability of a nuclear waste repository, indicates that incentives may help ahcieve the twin goals of increasing local support and decreasing local opposition to hosting nuclear waste facilities. Incentives are classified according to functional categories (i.e., mitigation, compensation, and reward), and prerequisites to the use of incentives are outlined (i.e., guarantee of public health and safety, some measure of local control, and a legitimation of negotiations during siting). Criteria for evaluating the utility of incentives packages may be more useful than single incentives, and nonmonetary incentives, such as independent monitoring and access to credible information, may be as important in eliciting support as monetary incentives. 54 references, 1 figure, 4 tables

    Objective We explored whether financial incentives have a role in patients′ decisions to accept (purchase) a continuous positive airway pressure (CPAP) device in a healthcare system that requires cost sharing. Design Longitudinal interventional study. Patients The group receiving financial incentive (n = 137, 50.8±10.6 years, apnea/hypopnea index (AHI) 38.7±19.9 events/hr) and the control group (n = 121, 50.9±10.3 years, AHI 39.9±22) underwent attendant titration and a two-week adaptation to CPAP. Patients in the control group had a co-payment of $330–660; the financial incentive group paid a subsidized price of $55. Results CPAP acceptance was 43% greater (p = 0.02) in the financial incentive group. CPAP acceptance among the low socioeconomic strata (n = 113) (adjusting for age, gender, BMI, tobacco smoking) was enhanced by financial incentive (OR, 95% CI) (3.43, 1.09–10.85), age (1.1, 1.03–1.17), AHI (>30 vs. CPAP (4.29, 1.05–17.51). Among average/high-income patients (n = 145) CPAP acceptance was affected by AHI (>30 vs. CPAP adherence was similar in the financial incentive and control groups, 35% and 39%, respectively (p = 0.82). Adherence rate was sensitive to education (+yr) (1.28, 1.06–1.55) and AHI (>30 vs. CPAP acceptance among low socioeconomic status patients. Thus, financial incentive should be applied as a policy to encourage CPAP treatment, especially among low socioeconomic strata patients. PMID:22479368

  13. The Promise of Tailoring Incentives for Healthy Behaviors.

    2016-01-01

    To describe how tailoring financial incentives for healthy behaviors to employees' goals, values, and aspirations might improve the efficacy of incentives. We integrate insights from self-determination theory (SDT) with principles from behavioral economics in the design of financial incentives by linking how incentives could help meet an employee's life goals, values, or aspirations. Tailored financial incentives could be more effective than standard incentives in promoting autonomous motivation necessary to initiate healthy behaviors and sustain them after incentives are removed. Previous efforts to improve the design of financial incentives have tested different incentive designs that vary the size, schedule, timing, and target of incentives. Our strategy for tailoring incentives builds on strong evidence that difficult behavior changes are more successful when integrated with important life goals and values. We outline necessary research to examine the effectiveness of this approach among at-risk employees. Instead of offering simple financial rewards for engaging in healthy behaviors, existing programs could leverage incentives to promote employees' autonomous motivation for sustained health improvements. Effective application of these concepts could lead to programs more effective at improving health, potentially at lower cost. Our approach for the first time integrates key insights from SDT, behavioral economics, and tailoring to turn an extrinsic reward for behavior change into an internalized, self-sustaining motivator for long-term engagement in risk-reducing behaviors.

  15. Empirical studies of regulatory restructuring and incentives

    Science.gov (United States)

    Knittel, Christopher Roland

    This dissertation examines the actions of firms when faced with regulatory restructuring. Chapter I examines the equilibrium pricing behavior of local exchange telephone companies under a variety of market structures. In particular, the pricing behavior of three services are analyzed: residential local service, business local service, and intraLATA toll service. Beginning in 1984, a variety of market structure changes have taken place in the local telecommunications industry. I analyze differences in the method of price-setting regulation and the restrictions on entry. Specifically, the relative pricing behavior under rate of return and price cap regulation is analyzed, as well as the impact of entry in the local exchange and intraLATA toll service markets. In doing so, I estimate an empirical model that accounts for the stickiness of rates in regulated industries that is based on firm and regulator decision processes in the presence of adjustment costs. I find that, faced with competitive pressures that reduce rates in one service, incumbent firm rates increase in other services, thereby reducing the benefits from competition. In addition, the findings suggest that price cap regulation leads to higher rates relative to rate-of-return regulation. Chapter 2 analyzes the pricing and investment behavior of electricity firms. Electricity and natural gas markets have traditionally been serviced by one of two market structures. In some markets, electricity and natural gas are sold by a dual-product regulated monopolist, while in other markets, electricity and natural gas are sold by separate single-product regulated monopolies. This paper analyzes the relative pricing and investment decisions of electricity firms operating in the two market structures. The unique relationship between these two products imply that the relative incentives of single and dual-product firms are likely to differ. Namely electricity and natural gas are substitutes in consumption while natural

    2016-05-01

    Tracking adolescent outcomes after inpatient hospitalization is important in informing clinical care for this age group, as inpatient care is one of the most expensive treatment modalities. This study examined 4 incentive strategies used to maintain adolescent participation in follow-up research (at 6, 12, and 18 mo) after their discharge from the hospital (N=267). A generalized estimation equation approach was taken to investigate whether different incentive strategies predicted adolescent completion of the follow-up assessments at each time point. Findings demonstrate that implementation of social worker contact significantly differed from other incentive strategies in increasing adolescent completion of follow-up assessments (Z=2.51, P=0.012) over the 3 time points, even when controlling for age and sex. Although these findings ultimately need to be confirmed through a randomized controlled study of incentive strategies, they provide preliminary support for the notion that relational incentives, such as maintaining contact with a member of the clinical team at the hospital, may be particularly important in promoting adolescent participation in outcomes research.

  17. Nonprice incentives and energy conservation.

    Asensio, Omar I; Delmas, Magali A

    2015-02-10

    In the electricity sector, energy conservation through technological and behavioral change is estimated to have a savings potential of 123 million metric tons of carbon per year, which represents 20% of US household direct emissions in the United States. In this article, we investigate the effectiveness of nonprice information strategies to motivate conservation behavior. We introduce environment and health-based messaging as a behavioral strategy to reduce energy use in the home and promote energy conservation. In a randomized controlled trial with real-time appliance-level energy metering, we find that environment and health-based information strategies, which communicate the environmental and public health externalities of electricity production, such as pounds of pollutants, childhood asthma, and cancer, outperform monetary savings information to drive behavioral change in the home. Environment and health-based information treatments motivated 8% energy savings versus control and were particularly effective on families with children, who achieved up to 19% energy savings. Our results are based on a panel of 3.4 million hourly appliance-level kilowatt-hour observations for 118 residences over 8 mo. We discuss the relative impacts of both cost-savings information and environmental health messaging strategies with residential consumers.

    To examine wellness programs with financial incentives and their effect on disparities in preventive care. Financial incentives were introduced by 15 large employers, from 2010 to 2013. Fifteen private employers. A total of 299 436 employees and adult dependents. Preventive services and participation in financial incentives. Multivariate linear regression. Disparities in preventive services widened after introduction of financial incentives. Asians were 3% more likely and African Americans were 3% less likely to receive wellness rewards than whites and non-Hispanics, controlling for other factors. Federal law limits targeting of wellness financial incentives by subgroups; thus, employers should consider outreach and culturally appropriate messaging.

    Firms offer highly complex contracts to their employees. These contracts contain a mix of incentives, such as fixed wages, bonus payments, promotion options, and layoff threats. In general, economists understand how incentives motivate employees but not why a particular mix should be used....... In this paper we present a model in which the observed incentive mix is an optimal contract. In particular, we show that it can be optimal for firms to combine cost-efficient incentives such as promotions and bonuses with layoffs. The intuition is that layoffs play a dual role. First, they create incentives...

    2008-10-12

    We present a brief overview of the incentive sensitization theory of addiction. This posits that addiction is caused primarily by drug-induced sensitization in the brain mesocorticolimbic systems that attribute incentive salience to reward-associated stimuli. If rendered hypersensitive, these systems cause pathological incentive motivation ('wanting') for drugs. We address some current questions including: what is the role of learning in incentive sensitization and addiction? Does incentive sensitization occur in human addicts? Is the development of addiction-like behaviour in animals associated with sensitization? What is the best way to model addiction symptoms using animal models? And, finally, what are the roles of affective pleasure or withdrawal in addiction?

    1981-05-01

    Several issues are analyzed on the effects that government subsidies and other incentives have on the use of solar energy in industry, as well as on other capital-intensive alternative energy supplies. Discounted cash flow analysis is used to compare tax deductions for fuel expenses with tax credits for capital investments for energy. The result is a simple expression for tax equity. The effects that market penetration of solar energy has on conventional energy prices are analyzed with a free market model. It is shown that net costs of a subsidy program to the society can be significantly reduced by price. Several government loan guarantee concepts are evaluated as incentives that may not require direct outlays of government funds; their relative effectiveness in achieving loan leverage through project financing, and their cost and practicality, are discussed.

The contractual relation has given an impact to the performance of the hedge fund industry, which benefited both fund managers and investors. Furthermore, it has created more investors and fund managers to participate in this high risk and high return investment. Currently, many issues on fee structures and performancebased incentives have been discussed. Do these issues affect the performance of the hedge fund in the market? This paper will investigate the issues in Australian market. It will empirically analyze the hedge fund performance in relation to the market performance and whether managerial incentives and discretions associated with better fund performance.

    Tax expenditures-reductions in income tax liability resulting from a special tax provision-are often used to achieve economic and social objectives. The arguments for petroleum production tax incentives usually encompass some combination of enhancing energy security, rewarding risk, or generating additional investment in new technologies. Generally, however, some portion of any tax expenditure is spend on activities that would have occurred anyway. This paper is a review of tax incentives for petroleum production found two to be of questionable merit. Others, including tax preferences for enhanced oil recovery methods, which offered the potential for better returns on the tax dollar. Increased use of enhanced oil recovery techniques could lead to additional environmental costs, however, and these need to be factored into any cost-benefit calculation

    In this study, we examine how development status and water scarcity shape people's perceptions of "hard path" and "soft path" water solutions. Based on ethnographic research conducted in four semi-rural/peri-urban sites (in Bolivia, Fiji, New Zealand, and the US), we use content analysis to conduct statistical and thematic comparisons of interview data. Our results indicate clear differences associated with development status and, to a lesser extent, water scarcity. People in the two less developed sites were more likely to suggest hard path solutions, less likely to suggest soft path solutions, and more likely to see no path to solutions than people in the more developed sites. Thematically, people in the two less developed sites envisioned solutions that involve small-scale water infrastructure and decentralized, community-based solutions, while people in the more developed sites envisioned solutions that involve large-scale infrastructure and centralized, regulatory water solutions. People in the two water-scarce sites were less likely to suggest soft path solutions and more likely to see no path to solutions (but no more likely to suggest hard path solutions) than people in the water-rich sites. Thematically, people in the two water-rich sites seemed to perceive a wider array of unrealized potential soft path solutions than those in the water-scarce sites. On balance, our findings are encouraging in that they indicate that people are receptive to soft path solutions in a range of sites, even those with limited financial or water resources. Our research points to the need for more studies that investigate the social feasibility of soft path water solutions, particularly in sites with significant financial and natural resource constraints.

    Utility incentive programs remain one of the most significant means of deploying commercialized, but underutilized building technologies to scale. However, these programs have been largely limited to component-based products (e.g., lamps, RTUs). While some utilities do provide ‘custom’ incentive programs with whole building and system level technical assistance, these programs require deeper levels of analysis, resulting in higher program costs. This results in custom programs being restricted to utilities with greater resources, and are typically applied mainly to large or energy-intensive facilities, leaving much of the market without cost effective access and incentives for these solutions. In addition, with increasingly stringent energy codes, cost effective component-based solutions that achieve significant savings are dwindling. Building systems (e.g., integrated façade, HVAC and/or lighting solutions) can deliver higher savings that translate into large sector-wide savings if deployed at the scale of these programs. However, systems application poses a number of challenges – baseline energy use must be defined and measured; the metrics for energy and performance must be defined and tested against; in addition, system savings must be validated under well understood conditions. This paper presents a sample of findings of a project to develop validated utility incentive program packages for three specific integrated building systems, in collaboration with Xcel Energy (CO, MN), ComEd, and a consortium of California Public Owned Utilities (CA POUs) (Northern California Power Agency(NCPA) and the Southern California Public Power Authority(SCPPA)). Furthermore, these program packages consist of system specifications, system performance, M&V protocols, streamlined assessment methods, market assessment and implementation guidance.

  15. Incentives, equity and the Able Chooser Problem.

    Science.gov (United States)

    Grill, Kalle

    2017-03-01

    Health incentive schemes aim to produce healthier behaviours in target populations. They may do so both by making incentivised options more salient and by making them less costly. Changes in costs only result in healthier behaviour if the individual rationally assesses the cost change and acts accordingly. Not all people do this well. Those who fail to respond rationally to incentives will typically include those who are least able to make prudent choices more generally. This group will typically include the least advantaged more generally, since disadvantage inhibits one's effective ability to choose well and since poor choices tend to cause or aggravate disadvantage. Therefore, within the target population, health benefits to the better off may come at the cost of aggravated inequity. This is one instance of a problem I name the Able Chooser Problem, previously emphasised by Richard Arneson in relation to coercive paternalism. I describe and discuss this problem by distinguishing between policy options and their effects on the choice situation of individuals. Both positive and negative incentives, as well as mandates that are less than perfectly effective, require some sort of rational deliberation and action and so face the Able Chooser Problem. In contrast, effective restriction of what options are physically available, as well as choice context design that makes some options more salient or appealing, does not demand rational agency. These considerations provide an equity-based argument for preferring smart design of our choice and living environment to incentives and mandates. Published by the BMJ Publishing Group Limited.

In the framework of an efficiency wage model, a short expected job tenure represents a disamenity that reduces the penalty from shirking. As this disamenity increases, workers have an incentive to continue providing a positive level of effort only if they are compensated by a higher wage. We endogenize the employment...

  18. The use of financial incentives in Australian general practice.

    2015-05-18

    To examine the uptake of financial incentive payments in general practice, and identify what types of practitioners are more likely to participate in these schemes. Analysis of data on general practitioners and GP registrars from the Medicine in Australia - Balancing Employment and Life (MABEL) longitudinal panel survey of medical practitioners in Australia, from 2008 to 2011. Income received by GPs from government incentive schemes and grants and factors associated with the likelihood of claiming such incentives. Around half of GPs reported receiving income from financial incentives in 2008, and there was a small fall in this proportion by 2011. There was considerable movement into and out of the incentives schemes, with more GPs exiting than taking up grants and payments. GPs working in larger practices with greater administrative support, GPs practising in rural areas and those who were principals or partners in practices were more likely to use grants and incentive payments. Administrative support available to GPs appears to be an increasingly important predictor of incentive use, suggesting that the administrative burden of claiming incentives is large and not always worth the effort. It is, therefore, crucial to consider such costs (especially relative to the size of the payment) when designing incentive payments. As market conditions are also likely to influence participation in incentive schemes, the impact of incentives can change over time and these schemes should be reviewed regularly.

    According to standard economic theory higher monetary incentives will lead to higher performance and higher effort independent of task, context, or individual. In many contexts this standard economic advice is implemented. Monetary incentives are, for example, used to enhance performance at workplace or to increase health-related behavior. However, the fundamental positive impact of monetary incentives has been questioned by psychologists as well as behavioral economists during the last decade, arguing that monetary incentives can sometimes even backfire. In this chapter, studies from proponents as well as opponents of monetary incentives will be presented. Specifically, the impact of monetary incentives on performance, prosocial, and health behavior will be discussed. Furthermore, variables determining whether incentives have a positive or negative impact will be identified. © 2016 Elsevier B.V. All rights reserved.

    2013-01-01

    Recently, the importance of renewable energy sources has increased significantly as climate change has become an important long term threat to global ecosystems and the world economy. In the face of increased concern about climate change and high fossil fuel costs together with a reduction in the primary energy sources such as oil, natural gas and coal, alternative energy sources (renewables) are increasingly needed to respond to the threat of climate change and growing energy demand in the world. Recent developments in Turkey, such as the liberalization of the electricity market and improvements in the renewable legislations, have accelerated the growth process and investment opportunities in the field of renewable energy. Turkey′s naturally endowed potential for renewables, such as solar, geothermal and wind, also accompanied these developments and attracted world attention to this market. In Turkey, renewable energy sources have gained great importance in the last decades due to growing energy demand and incentive policies which foster the utilization of renewable energy sources. This study aims to explore the availability and potential of renewable energy sources in Turkey and discuss the government policies and economic aspects. - highlights: • Turkey′s potential for renewable energy has attracted world attention. • Turkey has specific energy objectives in promoting renewable energy. • This paper evaluates recent incentives for renewable energy in Turkey. • Incentives in Turkey have led to more investment in renewable energy generation

  1. Optimal Paths in Gliding Flight

    Science.gov (United States)

    Wolek, Artur

    Underwater gliders are robust and long endurance ocean sampling platforms that are increasingly being deployed in coastal regions. This new environment is characterized by shallow waters and significant currents that can challenge the mobility of these efficient (but traditionally slow moving) vehicles. This dissertation aims to improve the performance of shallow water underwater gliders through path planning. The path planning problem is formulated for a dynamic particle (or "kinematic car") model. The objective is to identify the path which satisfies specified boundary conditions and minimizes a particular cost. Several cost functions are considered. The problem is addressed using optimal control theory. The length scales of interest for path planning are within a few turn radii. First, an approach is developed for planning minimum-time paths, for a fixed speed glider, that are sub-optimal but are guaranteed to be feasible in the presence of unknown time-varying currents. Next the minimum-time problem for a glider with speed controls, that may vary between the stall speed and the maximum speed, is solved. Last, optimal paths that minimize change in depth (equivalently, maximize range) are investigated. Recognizing that path planning alone cannot overcome all of the challenges associated with significant currents and shallow waters, the design of a novel underwater glider with improved capabilities is explored. A glider with a pneumatic buoyancy engine (allowing large, rapid buoyancy changes) and a cylindrical moving mass mechanism (generating large pitch and roll moments) is designed, manufactured, and tested to demonstrate potential improvements in speed and maneuverability.

    2016-01-01

    Background: An opportunity to address the needs of patients with common mental disorders (CMDs) resides in primary care. Barriers are restricting availability of treatment for CMDs in primary care. By understanding the incentives that promote and the disincentives that deter treatment for CMDs in a collaborative primary care context, this study aims to help contribute to goals of greater access to mental healthcare. Method: A qualitative pilot study using semi-structured interviews with thematic analysis. Results: Participants identified 10 themes of incentives and disincentives influencing quality treatment of CMDs in a collaborative primary care setting: high service demands, clinical presentation, patient-centred care, patient attributes, education, physician attributes, organizational, access to mental health resources, psychiatry and physician payment model. Conclusion: An understanding of the incentives and disincentives influencing care is essential to achieve greater integration and capacity for care for the treatment of CMDs in primary care.

    In order to obtain a well-defined path integral one often employs discretizations. In the case of General Relativity these generically break diffeomorphism symmetry, which has severe consequences since these symmetries determine the dynamics of the corresponding system. In this article we consider the path integral of reparametrization invariant systems as a toy example and present an improvement procedure for the discretized propagator. Fixed points and convergence of the procedure are discussed. Furthermore we show that a reparametrization invariant path integral implies discretization independence and acts as a projector onto physical states.

    The quantization of non-Abelian gauge theories in the temporal gauge is studied within Feynman's path integral approach. The standard asymptotic boundary conditions are only imposed on the transverse gauge fields. The fictituous longitudinal gauge quanta are eliminated asymptotically by modified boundary conditions. This abolishes the residual time-independent gauge transformations and leads to a unique fixing of the temporal gauge. The resulting path integral for the generating functional respects automatically Gauss's law. The correct gauge field propagator is derived. It does not suffer from gauge singularities at n x k = 0 present in the usual treatment of axial gauges. The standard principal value prescription does not work. As a check, the Wilson loop in temporal gauge is calculated with the new propagator. To second order (and to all orders in the Abelian case) the result agrees with the one obtained in the Feynman and Coulomb gauge. (orig.)

  6. Canadian incentives for oil and gas exploration. [Applicability to USA

    1980-04-01

    During the 1970s a number of different exploration and production incentive programs were put in place in Canada, in particular in the Province of Alberta, Canada's principal oil- and gas-producing province. The DOE/RA is evaluating Canadian incentives for oil and gas exploration, and this study is intended to provide information that will help guide DOE/RA in determining the applicability of Canadian incentive programs in US energy policy. The study describes and documents the fiscal structure in which the Canadian oil industry operates. The incentive features of pricing policy, taxation policy, and provincial royalty systems are discussed. A principal focus of the study is on one of the most important of Canada's specific incentive programs, the Alberta Exploratory Drilling Incentive Credit Program (EDICP). The study describes and evaluates the effect of the EDICP on increased oil and gas exploration activity. Similarly, the study also reviews and evaluates other specific incentive programs such as the Alberta Geophysical Incentive Program, Frontier Exploration Allowances, and various tar sand and heavy oil development incentives. Finally the study evaluates the applicability of Canadian incentives to US energy policy.

  7. What You Sow Is What You Reap? (Dis-Incentives for Adaptation Intentions in Farming

    Full Text Available Adaptation by farmers and other land managers responsible for climate-sensitive activities is central to ensuring resilience in the face of ongoing climate variability and change. However, there remains an adaptation deficit among agricultural producers: action to reduce vulnerability to the impacts of climate change is insufficient. To motivate adaptation, diverse incentives are in place most notably through the European Union’s Common Agricultural Policy which offers financial incentives to farmers. However, the effect of incentives on behaviour appears to be low. To better understand adaptation intentions, we report on the results of a survey experiment assessing framing effects on German farmers. Four framings of adaptation motifs—financial, norms, risk awareness, and technological innovation—are tested against a socio-cognitive model based on Protection Motivation Theory (PMT. According to PMT, adaptation intentions are a function of an individual’s risk and coping appraisal. Results show that, contrary to assumptions of profit maximizing individuals, economic incentives trigger fewer overall change intentions. Economic rewards do act on risk perception, but are less likely to trigger coping perception, while other treatments do. As coping perception is one of two socio-cognitive reactions to climate change, financial incentive structures fail to act on about half the factors leading to adaptation intentions. These effects dependent on subgroups, farm structures, and are mediated by climate experience. To support transitions towards robust adaptation, adaptation incentives must move beyond financial framings alone, and leverage on farmers’ recent experiences with adverse climate impacts, understandings of climate change, and the influence of social norms.

    1997-07-08

    In many path finding problems arising in practice, certain patterns of edge/vertex labels in the labeled graph being traversed are allowed/preferred, while others are disallowed. Motivated by such applications as intermodal transportation planning, the authors investigate the complexity of finding feasible paths in a labeled network, where the mode choice for each traveler is specified by a formal language. The main contributions of this paper include the following: (1) the authors show that the problem of finding a shortest path between a source and destination for a traveler whose mode choice is specified as a context free language is solvable efficiently in polynomial time, when the mode choice is specified as a regular language they provide algorithms with improved space and time bounds; (2) in contrast, they show that the problem of finding simple paths between a source and a given destination is NP-hard, even when restricted to very simple regular expressions and/or very simple graphs; (3) for the class of treewidth bounded graphs, they show that (i) the problem of finding a regular language constrained simple path between source and a destination is solvable in polynomial time and (ii) the extension to finding context free language constrained simple paths is NP-complete. Several extensions of these results are presented in the context of finding shortest paths with additional constraints. These results significantly extend the results in [MW95]. As a corollary of the results, they obtain a polynomial time algorithm for the BEST k-SIMILAR PATH problem studied in [SJB97]. The previous best algorithm was given by [SJB97] and takes exponential time in the worst case.

    Inomata, Akira; Junker, Georg

    2012-01-01

    Quantum mechanics in conical space is studied by the path integral method. It is shown that the curvature effect gives rise to an effective potential in the radial path integral. It is further shown that the radial path integral in conical space can be reduced to a form identical with that in flat space when the discrete angular momentum of each partial wave is replaced by a specific non-integral angular momentum. The effective potential is found proportional to the squared mean curvature of the conical surface embedded in Euclidean space. The path integral calculation is compatible with the Schrödinger equation modified with the Gaussian and the mean curvature. -- Highlights: ► We study quantum mechanics on a cone by the path integral approach. ► The path integral depends only on the metric and the curvature effect is built in. ► The approach is consistent with the Schrödinger equation modified by an effective potential. ► The effective potential is found to be of the “Jensen–Koppe” and “da Costa” type.

    2014-01-01

    In traffic research, management, and planning a number of path-based analyses are heavily used, e.g., for computing turn-times, evaluating green waves, or studying traffic flow. These analyses require retrieving the trajectories that follow the full path being analyzed. Existing path queries cannot...... sufficiently support such path-based analyses because they retrieve all trajectories that touch any edge in the path. In this paper, we define and formalize the strict path query. This is a novel query type tailored to support path-based analysis, where trajectories must follow all edges in the path...... a specific path by only retrieving data from the first and last edge in the path. To correctly answer strict path queries existing network-constrained trajectory indexes must retrieve data from all edges in the path.

    BACKGROUND Questionnaire surveys are important for surveying the health and disease behaviour of the population, but recent years have seen a fall in participation. Our study tested whether incentives can increase participation in these surveys.MATERIAL AND METHOD We sent a questionnaire on risk factors for colorectal cancer (height, weight, smoking, self-reported diagnoses, family medical history) to non-screened participants in a randomised colonoscopy screening study for colorectal cancer: participants who were invited but did not attend for colonoscopy examination (screening-invited) and persons who were not offered colonoscopy (control group). The persons were randomised to three groups: no financial incentive, lottery scratch cards included with the form, or a prize draw for a tablet computer when they responded to the form. We followed up all the incentive groups with telephone reminder calls, and before the prize draw for the tablet computer.RESULTS Altogether 3 705 of 6 795 persons (54.5  %) responded to the questionnaire; 43.5  % of those invited for screening and 65.6  % of the control group (p reminder calls, 39.2  % responded.

Use of telephone reminder calls and telephone interviews increased participation, but whether this is more effective than other methods requires further study.

    Padula, S.; Harou, J. J.

    2014-12-01

    This work attempts to model the infrastructure investment choices of privatized water utilities subject to rate of return and price cap regulation. The goal is to understand how regulation influences water companies' investment decisions such as their desire to engage in transfers with neighbouring companies. We formulate a profit maximization capacity expansion model that finds the schedule of new supply, demand management and transfer schemes that maintain the annual supply-demand balance and maximize a companies' profit under the 2010-15 price control process in England. Regulatory incentives for costs savings are also represented in the model. These include: the CIS scheme for the capital expenditure (capex) and incentive allowance schemes for the operating expenditure (opex) . The profit-maximizing investment program (what to build, when and what size) is compared with the least cost program (social optimum). We apply this formulation to several water companies in South East England to model performance and sensitivity to water network particulars. Results show that if companies' are able to outperform the regulatory assumption on the cost of capital, a capital bias can be generated, due to the fact that the capital expenditure, contrarily to opex, can be remunerated through the companies' regulatory capital value (RCV). The occurrence of the 'capital bias' or its entity depends on the extent to which a company can finance its investments at a rate below the allowed cost of capital. The bias can be reduced by the regulatory penalties for underperformances on the capital expenditure (CIS scheme); Sensitivity analysis can be applied by varying the CIS penalty to see how and to which extent this impacts the capital bias effect. We show how regulatory changes could potentially be devised to partially remove the 'capital bias' effect. Solutions potentially include allowing for incentives on total expenditure rather than separately for capex and opex and allowing

    The federal government offers a number of tax incentives to developers of biomass projects. This paper describes each tax benefit, explains what conditions must be met before the benefit is available, and offers practical insights gained from working for over 10 years in the field. Understanding what tax benefits are available is important because the more tax benefits a developer can qualify for in connection with his project, the less expensive the project will be to build and operate and the easier it will be to arrange financing because there will be higher returns in the project for potential investors

    In order to reduce the state deficit the French government plans to reduce the financial incentives in all sectors and particularly in the sector of renewable energies. The photovoltaic sector is the most hit with a tax credit rate dropping from 50% (in 2009) to 22.5% (in 2011). For the other renewable energy sectors the tax credit rate will be reduced by 10% in 2011. The French government wants the cost of the tax credit on the renewable energies to drop from 2.8*10 9 euros in 2009 to 2.0*10 9 euros in 2011. (A.C.)

    The paper is devoted to the study of incentive schemes when developing socio-economic systems. The article analyzes the existing incentive schemes. It is established that the traditional incentive mechanisms do not fully take into account the specifics of the creation of each socio-economic system and, as a rule, are difficult to implement. The incentive schemes based on the full-scale simulation approach, which allow the most complete information from the existing projects of creation of socio-economic systems to be extracted, are proposed. The statement of the problem is given, the method and algorithm of the full-scale simulation study of the efficiency of incentive functions is developed. The results of the study are presented. It is shown that the use of quadratic and piecewise linear functions of incentive allows the time and costs for creating social and economic systems to be reduced by 10%-15%.

    The theories of professions, public service motivation, and economic incentives explain the behaviour of the producers of publicly financed services differently. They emphasize professional norms, sector, and economic incentives, respectively. The few existing attempts to integrate these theories...... have, however, indicated that these factors interact. Using interviews, surveys and registers, the paper investigated how professional norms, economic incentives and sector affected the behaviour of Danish dentists and physicians. It was found that when strong professional norms existed, economic...... incentives were unimportant for both public and private employees. In contrast, when no firm professional norm applied, economic incentives affected behaviour. Controlling for different economic incentives, sector does not seem to affect the behaviour much. The results imply that the economic...

    Children with early-onset disruptive behavior disorder (DBD), especially those with callous-unemotional traits, are at risk of developing persistent and severe adult antisocial behavior. One possible underlying mechanism for persistence is deficient reward and loss sensitivity, i.e., deficient incentive processing. However, little is known about the relation between deficient incentive processing and persistence of antisocial behavior into adulthood or its relation with callous-unemotional and other psychopathic traits. In this study, we investigate the relationship between the neural correlates of incentive processing and both DBD persistence and psychopathic traits. In a sample of 128 adolescents (mean age 17.7) with a history of criminal offending before age 12, functional magnetic resonance imaging was performed during a monetary incentive delay task designed to assess neural responses during incentive processing. Neural activation during incentive processing was then associated with DBD persistence and psychopathic traits, measured with the Youth Psychopathic Traits Inventory. Compared with both healthy control subjects and youths who had desisted from DBD, persistent DBD subjects showed lower neural responses in the ventral striatum during reward outcomes and higher neural responses in the amygdala during loss outcomes. Callous-unemotional traits were related to lower neural responses in the amygdala during reward outcomes, while other psychopathic traits were not related to incentive processing. In the current study, aberrant incentive processing is related to persistence of childhood antisocial behavior into late adolescence and to callous-unemotional traits. This mechanism may underlie treatment resistance in a subgroup of antisocial youth and provide a target for intervention. Copyright © 2015 Society of Biological Psychiatry. Published by Elsevier Inc.

    This report reviews recent DSM shareholder incentive designs and performance at 10 US utilities identifies opportunities for regulators to improve the design of DSM shareholder incentive mechanisms to increase the procurement of cost-effective DSM resources. We develop six recommendations: (1) apply shared-savings incentives to DSM resource programs; (2) use markup incentives for individual programs only when net benefits are difficult to measure, but are known to be positive; (3) set expected incentive payments based on covering a utility's open-quotes hidden costs,close quotes which include some transitional management and risk-adjusted opportunity costs; (4) use higher marginal incentives rates than are currently found in practice, but limit total incentive payments by adding a fixed charge; (5) mitigate risks to regulators and utilities by lowering marginal incentive rates at high and low performance levels; and (6) use an aggregate incentive mechanism for all DSM resource programs, with limited exceptions (e.g., information programs where markups are more appropriate)

    The importance of social and institutional issues in the siting of nuclear waste facilities has been recognized in recent years. Limited evidence from a survey of rural Wisconsin residents in 1980 indicates that incentives may help achieve the twin goals of increasing local support and decreasing local opposition to hosting nuclear waste facilities. Incentives are classified according to functional categories (i.e., mitigation, compensation, and reward) and the conditions which may be prerequisites to the use of incentives are outlined (i.e., guarantee of public health and safety, some measure of local control, and a legitimation of negotiations during siting). Criteria for evaluating the utility of incentives in nuclear waste repository siting are developed. Incentive packages may be more useful than single incentives, and nonmonetary incentives, such as independent monitoring and access to credible information, may be as important in eliciting support as monetary incentives. Without careful attention to prerequisites in the siting process it is not likely that incentives will facilitate the siting process.

    The success of any dental practice depends, among other factors, on the critical role of staff employees. In order to encourage desired staff behaviors, incentive systems can be designed for employee dentists, assistants/hygienists and managers. A survey of dental franchises was conducted in 1987 for the purpose of examining their incentive control systems. The specific incentives employed by these dental franchises for their employees are analyzed. The implications of these incentive systems used by dental franchise organizations for all dental practices are then discussed.

    Full Text Available In many countries tax incentives are a popular means of realizing political, economic and social objectives. The main motive of their application is often to achieve and accelerate the selected activities in the public interest and also stimulate development of industry, and induce growth in research and investment. The key element that helps a company achieve a competitive advantage is innovation. Global competition forces the production of unique products and services. Tax incentives in science, research and development are important in stimulating innovation. The purpose of this article is to show the level of managerial awareness about R&D tax incentives, the level of R&D tax incentive usage by companies in Poland, and main obstacles that managers meet with R&D tax incentives in practice. We explore R&D tax incentives as a government instrument on R&D management and aim to find the reasons why Polish companies do not take advantage of them. We examine 275 companies using a semi-structured questi onnaire. Our findings suggest that many firms report lack of knowledge about such incentives, and firms find many obstacles to reach all of the requirements which are necessary to use the incentive. Due to our analysis we find that large firms, especially those that implement innovation, are more likely to use the tax incentives, but small and medium sized companies find more obstacle. The effect of this tax policy is significant mainly in large, high-tech sector firms.

    There is an increased use of key performance indicators and incentive schemes in the petroleum industry. Applying modern incentive theory, we explore what implications this management trend has for injury and major accident prevention efforts and safety. Can economic incentives be designed for accident prevention activities? In cases where this is not possible, what are the challenges for the safety efforts? In particular, how are safety efforts affected by enhanced economic incentives for other performance dimensions like production and rate of return? Can safety be neglected? What remedies are available?

  13. Dynamic Incentives in Microfinance Group Lending

    2012-04-01

    Full Text Available One of the most essential tools of poverty reduction would be the viable expansion of institutional credit facilities to large sections of the people who neither have adequate collateral nor credit history to secure a loan. In this backdrop, social collateral is popularized through the group lending programs to address the credit market problems. Microfinance through group lending is acting as a screening device; the joint liability mechanism creates incentives for internal monitoring. Hence, it has received a lot of attention from policy makers as well as academicians. It is playing an important role in delivering financial services to the “socially and economically excluded” poor, in general, and women, in particular. The group lending works with various dynamic incentives. One such kind is principle of progressive lending and it plays a vital role in sustaining the groups for the persistent delivery of microfinance services to its members. In progressive lending, a typical borrower receives very small amounts at first, which increases with good repayment conduct or it links new, larger loans to past repayment. This article explores possible theoretical and empirical relationship between progressive lending and its determinants in group lending approach. The primary survey was conducted in 10 villages covering 106 self-help groups and 318 members in Karnataka, India. The empirical results show the progressive lending amount rising up to 698% of the initial loan of the self-help groups.

  14. Residential dual energy programs: Tariffs and incentives

    International Nuclear Information System (INIS)

    Doucet, J.A.

    1992-01-01

    The problem of efficiently pricing electricity has been of concern to economists and policy makers for some time. A natural solution to variable demand is tariffs to smooth demand and reduce the need for excessive reserve margins. An alternative approach is dual energy programs whereby electric space heating systems are equipped with a secondary system (usually oil) which is used during periods of peak demand. Comments are presented on two previous papers (Bergeron and Bernard, 1991; Sollows et al., 1991) published in Energy Studies Review, applying them to Hydro Quebec tariff structure and dual energy programs. The role of tariffs in demand-side management needs to be considered more fully. Hydro-Quebec's bi-energy tariff structure could be modified by using positive incentives to make use of bi-energy attractive below -12 C to give the following benefits. The modified tariff would be easier for consumers to understand, corrects the misallocation problem due to differential pricing in the current tariff, transfers the risk related to price fluctuations of the alternative energy source from the consumer to the utility, and corrects the potential avoidance problem due to the negative incentive of the current tariff. 21 refs

  15. Community Forestry Incentives and Challenges in Mozambique

    Directory of Open Access Journals (Sweden)

    Almeida A. Sitoe

    2015-12-01

    Full Text Available Although communities have been living within forests and dependent on forest resources, in Mozambique, their role was not formally recognized until the late 1990s. The forest law of 1997 was the first to refer to communities as stakeholders in the forest sector, in line with the national Policy and Strategy for the Development of the Forestry and Wildlife Sector. As a new element, several pilot projects were established during the late 1990s and early 2000s to produce lessons that would inform policy and technical aspects. Community forestry received most of the attention until the first decade of this century, however, it seems that while communities have gained a role in the management of the forest sector, there are still challenges to fully implementing and securing community forestry initiatives. In this study, we document the advent and evolution of community forestry in Mozambique, discuss the conditions for success in community forestry, and discuss two cases of community forestry that have survived over beyond the end of external support. We conclude that devolution and training are the basic incentives, but additional incentives, including diversification of sources of revenue from non-destructive forestry activities, are required to maintain the stability of community forestry over time.

  16. Universal health insurance through incentives reform.

    Science.gov (United States)

    Enthoven, A C; Kronick, R

    1991-05-15

    Roughly 35 million Americans have no health care coverage. Health care expenditures are out of control. The problems of access and cost are inextricably related. Important correctable causes include cost-unconscious demand, a system not organized for quality and economy, market failure, and public funds not distributed equitably or effectively to motivate widespread coverage. We propose Public Sponsor agencies to offer subsidized coverage to those otherwise uninsured, mandated employer-provided health insurance, premium contributions from all employers and employees, a limit on tax-free employer contributions to employee health insurance, and "managed competition". Our proposed new government revenues equal proposed new outlays. We believe our proposal will work because efficient managed care does exist and can provide satisfactory care for a cost far below that of the traditional fee-for-service third-party payment system. Presented with an opportunity to make an economically responsible choice, people choose value for money; the dynamic created by these individual choices will give providers strong incentives to render high-quality, economical care. We believe that providers will respond to these incentives.

  17. Unlocking the potential of established products: toward new incentives rewarding innovation in Europe.

    2017-01-01

    Background : Many established products (EPs - marketed for eight years or more) are widely used off-label despite little evidence on benefit-risk ratio. This exposes patients to risks related to safety and lack of efficacy, and healthcare providers to liability. Introducing new indications for EPs may represent a high societal value; however, manufacturers rarely invest in R&D for EPs. The objective of this research was to describe incentives and disincentives for developing new indications for EPs in Europe and to investigate consequences of current policies. Methods : Targeted literature search and expert panel meetings. Results : Within the current European-level and national-level regulatory framework there are limited incentives for development of new indications with EPs. Extension of indication normally does not allow the price to be increased or maintained, the market protection period to be extended, or exclusion from a reference price system. New indication frequently triggers re-evaluation, resulting in price erosion, regardless of the level of added value with the new indication. In consequence, manufacturers are more prone to undertake R&D efforts at early to mid-stage of product life cycle rather than with EPs, or to invest in new chemical entities, even in therapeutic areas with broad off-label use. This represents a potentially missed opportunity as developing new indications for EPs offers an alternative to off-label use or lengthy and expensive R&D for new therapies, opens new opportunities for potentially cost-effective treatment alternatives, as well as greater equity in patients' access to treatment options. Conclusion : There are potential benefits from the development of new indications for EPs that are currently not being realized due to a lack of regulatory and pricing incentives in Europe. Incentives for orphan or paediatric drugs have proven to be effective in promoting R&D. Similarly, incentives to promote R&D in EPs should be developed

  18. Path integration on hyperbolic spaces

    Grosche, C [Hamburg Univ. (Germany). 2. Inst. fuer Theoretische Physik

    1991-11-01

    Quantum mechanics on the hyperbolic spaces of rank one is discussed by path integration technique. Hyperbolic spaces are multi-dimensional generalisation of the hyperbolic plane, i.e. the Poincare upper half-plane endowed with a hyperbolic geometry. We evalute the path integral on S{sub 1} {approx equal} SO (n,1)/SO(n) and S{sub 2} {approx equal} SU(n,1)/S(U(1) x U(n)) in a particular coordinate system, yielding explicitly the wave-functions and the energy spectrum. Futhermore we can exploit a general property of all these spaces, namely that they can be parametrized by a pseudopolar coordinate system. This allows a separation in path integration over spheres and an additional path integration over the remaining hyperbolic coordinate, yielding effectively a path integral for a modified Poeschl-Teller potential. Only continuous spectra can exist in all the cases. For all the hyperbolic spaces of rank one we find a general formula for the largest lower bound (zero-point energy) of the spectrum which is given by E{sub O} = h{sup 2} /8m(m{sub {alpha}} +2m{sub 2} {alpha}){sup 2} (m {alpha} and m{sub 2}{alpha} denote the dimension of the root subspace corresponding to the roots {alpha} and 2{alpha}, respectively). I also discuss the case, where a constant magnetic field on H{sup n} is incorporated. (orig.).

  20. Path Integrals in Quantum Mechanics

    International Nuclear Information System (INIS)

    Louko, J

    2005-01-01

    Jean Zinn-Justin's textbook Path Integrals in Quantum Mechanics aims to familiarize the reader with the path integral as a calculational tool in quantum mechanics and field theory. The emphasis is on quantum statistical mechanics, starting with the partition function Tr exp(-β H) and proceeding through the diffusion equation to barrier penetration problems and their semiclassical limit. The 'real time' path integral is defined via analytic continuation and used for the path-integral representation of the nonrelativistic S-matrix and its perturbative expansion. Holomorphic and Grassmannian path integrals are introduced and applied to nonrelativistic quantum field theory. There is also a brief discussion of path integrals in phase space. The introduction includes a brief historical review of path integrals, supported by a bibliography with some 40 entries. As emphasized in the introduction, mathematical rigour is not a central issue in the book. This allows the text to present the calculational techniques in a very readable manner: much of the text consists of worked-out examples, such as the quartic anharmonic oscillator in the barrier penetration chapter. At the end of each chapter there are exercises, some of which are of elementary coursework type, but the majority are more in the style of extended examples. Most of the exercises indeed include the solution or a sketch thereof. The book assumes minimal previous knowledge of quantum mechanics, and some basic quantum mechanical notation is collected in an appendix. The material has a large overlap with selected chapters in the author's thousand-page textbook Quantum Field Theory and Critical Phenomena (2002 Oxford: Clarendon). The stand-alone scope of the present work has, however, allowed a more focussed organization of this material, especially in the chapters on, respectively, holomorphic and Grassmannian path integrals. In my view the book accomplishes its aim admirably and is eminently usable as a textbook

    Many people aim to change their lifestyle, but have trouble acting on their intentions. Behavioral economic incentives and related emotions can support commitment to personal health goals, but the related emotions remain unexplored. In a regret lottery, winners who do not attain their health goals do not get their prize but receive feedback on what their forgone earnings would have been. This counterfactual feedback should provoke anticipated regret and increase commitment to health goals. We explored which emotions were actually expected upon missing out on a prize due to unsuccessful weight loss and which incentive-characteristics influence their likelihood and intensity. Participants reported their expected emotional response after missing out on a prize in one of 12 randomly presented incentive-scenarios, which varied in incentive type, incentive size and deadline distance. Participants primarily reported feeling disappointment, followed by regret. Regret was expected most when losing a lottery prize (vs. a fixed incentive) and intensified with prize size. Multiple features of the participant and the lottery incentive increase the occurrence and intensity of regret. As such, our findings can be helpful in designing behavioral economic incentives that leverage emotions to support health behavior change.

    Nudges, creating simple processes or structures that guide people toward a particular behaviour choice, are potentially a powerful tool for health promotion. User financial incentives could be a monetary form of such nudges. Given the challenges of chronic disease prevention, interventions such as nudges should be explored further. However, there would appear to be limited rationale for pursuing financial incentives as nudges.

    2004-12-01

    In theory, competitive electricity markets provide incentives for efficient investment in generation capacity. We show that if consumers and investors are risk averse, investment is efficient only if investors in generation capacity can sign long-term contracts with consumers. Otherwise the uncovered price risk increases financing costs, reduces equilibrium investment levels, distorts technology choice towards less capital-intensive generation and reduces consumer utility. We observe insufficient levels of long-term contracts in existing markets, possibly because retail companies are not credible counter-parties if their final customers can switch easily between them. With a consumer franchise, retailers can sign long-term contracts, but this solution comes at the expense of retail competition. Alternative capacity mechanisms to stimulate investment are discussed.

  8. Operator and contractor benefit from incentive contracts

    International Nuclear Information System (INIS)

    Brandon, B.

    1991-01-01

    This book reports that with incentive contracts, drilling and service contractors assume greater responsibility for operations. That helps them to align their goals more closely with those of the operator. This achieves a more equitable division of the risks. Many operators and contractors believe this is a more appropriate approach to contracting drilling services. As they assume manageable responsibility, each party also has opportunities for greater reward. Innovations in cooperation can create a win-win situation. In a win-win contract all parties benefit from the new relationships between operator, contractor, and service company. The win-win situation can only be achieved by allowing the contracting parties to become much more closely involved in drilling operations. This is the primary motivation behind development of more productive contracting strategies

    Villa, Silvia; Patrone, Fioravante

    2009-12-01

    The problem of kidney exchanges shares common features with the classical problem of exchange of indivisible goods studied in the mechanism design literature, while presenting additional constraints on the size of feasible exchanges. The solution of a kidney exchange problem can be summarized in a mapping from the relevant underlying characteristics of the players (patients and their donors) to the set of matchings. The goal is to select only matchings maximizing a chosen welfare function. Since the final outcome heavily depends on the private information in possess of the players, a basic requirement in order to reach efficiency is the truthful revelation of this information. We show that for the kidney exchange problem, a class of (in principle) efficient mechanisms does not enjoy the incentive compatibility property and therefore is subject to possible manipulations made by the players in order to profit of the misrepresentation of their private information.

    First, an overall picture is presented of the extension of the use of cogeneration by the Italian brick industry. The particular suitability and usefulness of this form of energy to the brick industry are pointed out. Then a look is given at the legal and financial incentives which have been built into the National Energy Plan to encourage on-site production by Italian industries. Finally, a review is made of initiatives made by SNAM (the Italian National Methane Distribution Society) to develop a favourable tariff structure for on-site power producers using methane as their energy source, as well as, of the Society's efforts to set up a cogeneration equipment consulting service which would provide advice on cogeneration plant design, operation and maintenance

  11. Successive duopoly under moral hazard: Will incentive contracts persist?

    Directory of Open Access Journals (Sweden)

    Marta Fernández-Olmos

    2009-07-01

    Full Text Available The central purpose of this paper is to examine the incentive contract as an equilibrium phenomenon. We analyse a model of vertical differentiation in which we deal with the strategic role of the competitor’s decisions in a successive duopoly. Is it better for a processor to offer an incentive contract to an upstream producer or the spot market? We determine the equilibrium of a game in which the processors simultaneously decide whether to offer an incentive contract or to continue at the spot market to acquire their input. Our results show that under successive duopoly, offering an incentive contract constitutes the unique equilibrium solution, which highlights the incentive contract persistence.

    Dr. Nikolas Emmanuel's examines the use of an incentives approach in managing intrastate conflict in Africa because in many cases, risks and costs make applications of hard power alone unfeasible. Furthermore, simply ignoring episodes of civil conflict in the hope that they will "burn themselves...... out"� does not appear to be a viable alternative. That said, both noncoercive and coercive incentive strategies exist and have been deployed by third parties in a variety of conflict situations. Such incentives seek to manage conflict by encouraging political bargaining. The clear intention...... parties can help manage conflicts. Second, it offers a typology of the available incentive strategies, classifying them along noncoercive and coercive lines. Thus, the article outlines the possibilities offered by an incentives approach, focusing on examples drawn from recent African cases....

A bi-level Stackelberg game model is proposed to search for the optimal incentive mechanism under a one-leader and multi-followers gaming framework. A multi-agent simulation platform was developed to investigate the effectiveness of the incentive mechanism using an independent system operator (ISO and multiple power generating companies (GenCos. Further, a Q-learning approach was implemented to analyze and assess the response of GenCos to the incentive menu. Numerical examples are provided to demonstrate the effectiveness of the incentive contract.

  14. Role of contingency in striatal response to incentive in adolescents with anxiety.

    Science.gov (United States)

    Benson, Brenda E; Guyer, Amanda E; Nelson, Eric E; Pine, Daniel S; Ernst, Monique

    2015-03-01

    This study examines the effect of contingency on reward function in anxiety. We define contingency as the aspect of a situation in which the outcome is determined by one's action-that is, when there is a direct link between one's action and the outcome of the action. Past findings in adolescents with anxiety or at risk for anxiety have revealed hypersensitive behavioral and neural responses to higher value rewards with correct performance. This hypersensitivity to highly valued (salient) actions suggests that the value of actions is determined not only by outcome magnitude, but also by the degree to which the outcome is contingent on correct performance. Thus, contingency and incentive value might each modulate reward responses in unique ways in anxiety. Using fMRI with a monetary reward task, striatal response to cue anticipation is compared in 18 clinically anxious and 20 healthy adolescents. This task manipulates orthogonally reward contingency and incentive value. Findings suggest that contingency modulates the neural response to incentive magnitude differently in the two groups. Specifically, during the contingent condition, right-striatal response tracks incentive value in anxious, but not healthy, adolescents. During the noncontingent condition, striatal response is bilaterally stronger to low than to high incentive in anxious adolescents, while healthy adolescents exhibit the expected opposite pattern. Both contingency and reward magnitude differentiate striatal activation in anxious versus healthy adolescents. These findings may reflect exaggerated concern about performance and/or alterations of striatal coding of reward value in anxious adolescents. Abnormalities in reward function in anxiety may have treatment implications.

    Although over 70% of homeless individuals smoke, few studies have examined the effectiveness of smoking cessation interventions in this vulnerable population. The purpose of this pilot study was to compare the effectiveness of shelter-based smoking cessation clinic usual care (UC) to an adjunctive contingency management (CM) treatment that offered UC plus small financial incentives for smoking abstinence. Sixty-eight homeless individuals in Dallas, Texas (recruited in 2012) were assigned to UC (n=58) or UC plus financial incentives (CM; n=10) groups and were followed for 5 consecutive weeks (1 week pre-quit through 4 weeks post-quit). A generalized linear mixed model regression analysis was conducted to compare biochemically-verified abstinence rates between groups. An additional model examined the interaction between time and treatment group. The participants were primarily male (61.8%) and African American (58.8%), and were 49 years of age on average. There was a significant effect of treatment group on abstinence overall, and effects varied over time. Follow-up logistic regression analyses indicated that CM participants were significantly more likely than UC participants to be abstinent on the quit date (50% vs. 19% abstinent) and at 4 weeks post-quit (30% vs. 1.7% abstinent). Offering small financial incentives for smoking abstinence may be an effective way to facilitate smoking cessation in homeless individuals. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Artificial intelligence (AI), especially deep learning, has the potential to fundamentally alter clinical radiology. AI algorithms, which excel in quantifying complex patterns in data, have shown remarkable progress in applications ranging from self-driving cars to speech recognition. The AI application within radiology, known as radiomics, can provide detailed quantifications of the radiographic characteristics of underlying tissues. This information can be used throughout the clinical care path to improve diagnosis and treatment planning, as well as assess treatment response. This tremendous potential for clinical translation has led to a vast increase in the number of research studies being conducted in the field, a number that is expected to rise sharply in the future. Many studies have reported robust and meaningful findings; however, a growing number also suffer from flawed experimental or analytic designs. Such errors could not only result in invalid discoveries, but also may lead others to perpetuate similar flaws in their own work. This perspective article aims to increase awareness of the issue, identify potential reasons why this is happening, and provide a path forward.

    We introduce a formulation for the general task of finding diverse shortest paths between two end-points. Our approach is not linked to a specific biological problem and can be applied to a large variety of images thanks to its generic implementation as a user-friendly ImageJ/Fiji plugin. It relies on the introduction of additional layers in a Viterbi path graph, which requires slight modifications to the standard Viterbi algorithm rules. This layered graph construction allows for the specification of various constraints imposing diversity between solutions. The software allows obtaining a collection of diverse shortest paths under some user-defined constraints through a convenient and user-friendly interface. It can be used alone or be integrated into larger image analysis pipelines. http://bigwww.epfl.ch/algorithms/diversepathsj. michael.unser@epfl.ch or fred.hamprecht@iwr.uni-heidelberg.de.

    Understanding how and how far information, behaviors, or pathogens spread in social networks is an important problem, having implications for both predicting the size of epidemics, as well as for planning effective interventions. There are, however, two main challenges for inferring spreading paths in real-world networks. One is the practical difficulty of observing a dynamic process on a network, and the other is the typical constraint of only partially observing a network. Using static, structurally realistic social networks as platforms for simulations, we juxtapose three distinct paths: (1) the stochastic path taken by a simulated spreading process from source to target; (2) the topologically shortest path in the fully observed network, and hence the single most likely stochastic path, between the two nodes; and (3) the topologically shortest path in a partially observed network. In a sampled network, how closely does the partially observed shortest path (3) emulate the unobserved spreading path (1)? Although partial observation inflates the length of the shortest path, the stochastic nature of the spreading process also frequently derails the dynamic path from the shortest path. We find that the partially observed shortest path does not necessarily give an inflated estimate of the length of the process path; in fact, partial observation may, counterintuitively, make the path seem shorter than it actually is.

    Reducing costs and increasing benefits for rural communities coexisting with large carnivores is necessary for conservation of jaguar (Panthera onca) and puma (Puma concolor). To design acceptable incentives, stakeholders must be involved in the process. We conducted an innovative, structured, group communication process based on a Delphi technique as a template for identifying potential incentives. Community workshops with 133 members of 7 communities and surveys with 25 multidisciplinary experts from government, nongovernmental organizations, and academia provided iterative data to design a plan of incentives through 4 rounds of discussion. The final product integrated 862 ideas into 6 types of incentives: organization of communities, mechanisms for improved dialogue, citizen technical assistance, green labeling for community products, payment for the ecosystem service of biodiversity, and an assessment of financial alternatives. We used quantitative and qualitative techniques to indicate support for decisions about the design of incentives, which reduced researcher subjectivity. The diverse incentives developed and the cooperation from multiple stakeholders resulted in an incentive plan that integrated issues of governance, equity, and social norms. © 2018 Society for Conservation Biology.

    The Western Business Unit Bakersfield drilling department of Chevron, U.S.A. Production Company developed a drilling performance incentive contract that was implemented during 1994 in the Lost Hills field of California. The performance incentive contract (PIC) financially rewarded all of the drilling contractor's rig employees for outperforming pre-established drilling performance goals. The key elements of the performance incentive program are: (1) Goals that rigger incentives are based on cost categories that are controllable by the drilling team; (2) Goals were established using a database of past years performance; (3) Goals that are not achieved negatively impact the incentive earned in an effort to deter repeated errors; (4) Accidents that occur on the job negatively impact the incentive earned; (5) Administration of the program is not time consuming. The results of using an incentive contract in the Lost Hills drilling program are: (1) Time and cost of operations are reduced; (2) The results are measurable and repeatable; (3) A team environment develops in which ideas are shared and acted upon by crew members and supervisory personnel

    This paper (1) estimates the total costs of federal expenditures in support of incentives for the development of commercial nuclear energy through 1988, and (2) analyzes the results and benefits to the nation of this federal investment. The federal incentives analyzed include research and development, regulation of commercial nuclear energy, tax incentives, waste management and disposal, enrichment plants, liability insurance, the uranium mining industry, and all other federal support activities. The authors estimate that net federal incentives totaled about $45-50 billion (1988 dollars). They estimate the results of the federal incentives, focusing on six categories, namely, electric energy produced, the total (direct plus indirect) economic benefits of the industry created, R and D program benefits, value of energy imports displaced, environmental effects, and health, safety, and risk effects. The results total $1.9 trillion, with approximately $250-300 billion identified as net benefits. The authors conclude that the high return on the investment justified federal incentives for nuclear energy development over the past four decades and that the federal government and the nation have received a significant return on the incentives investment

    The deployment of solar photovoltaic (PV) systems has grown rapidly over the last decade, partly because of various government incentives. In the United States, among the largest and longest-running incentives have been those established in California. Building on past research, this report addresses the still-unanswered question: to what degree have the direct PV incentives in California been passed through from installers to consumers? This report helps address this question by carefully examining the residential PV market in California (excluding a certain class of third-party-owned PV systems) and applying both a structural-modeling approach and a reduced-form regression analysis to estimate the incentive pass-through rate. The results suggest an average pass-through rate of direct incentives of nearly 100%, though with regional differences among California counties. While these results could have multiple explanations, they suggest a relatively competitive market and well-functioning subsidy program. Further analysis is required to determine whether similar results broadly apply to other states, to other customer segments, to all third-party-owned PV systems, or to all forms of financial incentives for solar (considering not only direct state subsidies, but also utility electric bill savings and federal tax incentives).

    Managed care organizations use explicit financial incentives to influence physicians' use of resources. This has contributed to concerns regarding conflicts of interest for physicians and adverse effects on the quality of patient care. In light of recent publicized legislative and legal battles about this issue, we reviewed the literature and analyzed studies that examine the effect of these explicit financial incentives on the behavior of physicians. The method used to undertake the literature review followed the approach set forth in the Cochrane Collaboration handbook. Our literature review revealed a paucity of data on the effect of explicit financial incentives. Based on this limited evidence, explicit incentives that place individual physicians at financial risk appear to be effective in reducing physician resource use. However, the empirical evidence regarding the effectiveness of bonus payments on physician resource use is mixed. Similarly, our review revealed mixed effects of the influence of explicit financial incentives on the quality of patient care. The effect of explicit financial incentives on physician behavior is complicated by a lack of understanding of the incentive structure by the managed care organization and the physician. The lack of a universally acceptable definition of quality renders it important that future researchers identify the term explicitly.

    We study a class of controlled differential equations driven by rough paths (or rough path realizations of Brownian motion) in the sense of Lyons. It is shown that the value function satisfies a HJB type equation; we also establish a form of the Pontryagin maximum principle. Deterministic problems of this type arise in the duality theory for controlled diffusion processes and typically involve anticipating stochastic analysis. We make the link to old work of Davis and Burstein (Stoch Stoch Rep 40:203–256, 1992) and then prove a continuous-time generalization of Roger’s duality formula [SIAM J Control Optim 46:1116–1132, 2007]. The generic case of controlled volatility is seen to give trivial duality bounds, and explains the focus in Burstein–Davis’ (and this) work on controlled drift. Our study of controlled rough differential equations also relates to work of Mazliak and Nourdin (Stoch Dyn 08:23, 2008).

  11. Using financial incentives to improve value in orthopaedics.

    2012-04-01

    A variety of reforms to traditional approaches to provider payment and benefit design are being implemented in the United States. There is increasing interest in applying these financial incentives to orthopaedics, although it is unclear whether and to what extent they have been implemented and whether they increase quality or reduce costs. We reviewed and discussed physician- and patient-oriented financial incentives being implemented in orthopaedics, key challenges, and prerequisites to payment reform and value-driven payment policy in orthopaedics. We searched the MEDLINE database using as search terms various provider payment and consumer incentive models. We retrieved a total of 169 articles; none of these studies met the inclusion criteria. For incentive models known to the authors to be in use in orthopaedics but for which no peer-reviewed literature was found, we searched Google for further information. Provider financial incentives reviewed include payments for reporting, performance, and patient safety and episode payment. Patient incentives include tiered networks, value-based benefit design, reference pricing, and value-based purchasing. Reform of financial incentives for orthopaedic surgery is challenged by (1) lack of a payment/incentive model that has demonstrated reductions in cost trends and (2) the complex interrelation of current pay schemes in today's fragmented environment. Prerequisites to reform include (1) a reliable and complete data infrastructure; (2) new business structures to support cost sharing; and (3) a retooling of patient expectations. There is insufficient literature reporting the effects of various financial incentive models under implementation in orthopaedics to know whether they increase quality or reduce costs. National concerns about cost will continue to drive experimentation, and all anticipated innovations will require improved collaboration and data collection and reporting.

They generalize the usually known potentials by the incorporation of a fractional power behaviour and strongly anharmonic terms. We find four different kinds of such potentials, the first is related to the Coulomb potential, the second is an anharmonic confinement potential, and the third and the fourth are related to the Manning-Rosen potential.

Another peculiarity is associated with appearance of the operator q which provides a complete definition of the wave functions out of the physical region. arguments are given upporting the validity of the cited statament in the general case

  16. The Architecture of Emission Allowance Markets and Incentives for Investment in Electricity

    International Nuclear Information System (INIS)

    Palmer, Karen; Burtraw, Dallas

    2007-06-01

    Regulating emissions through a cap-and-trade mechanism provides firms with more options for coming into compliance with an environmental rule than just installing emissions controls. Research on the SO 2 and NO x cap and trade programs in the US suggest that by placing a price on each ton of emissions these programs encourage R and D into improving the emissions reducing capability of control technologies and encourage investment in other types of know how. This is exemplified, for example, by experiments with blending of low and medium sulphur coals, which allows for cost-effective reductions in emissions especially along a transition path to tighter SO 2 constraints over time. Looking ahead to future climate regulation, the importance of continuous incentives for control of emissions that are priced under the regulation should not be under-estimated. Some have suggested that binding restrictions on CO 2 emissions should be postponed until low-emitting technologies (carbon capture and sequestration) or non emitting technologies (renewables) experience a major technological break through and that the main focus of public resources should be on encouraging technological advance in these areas. Experience with SO 2 regulation suggests that pricing emissions will produce unexpected innovations to reduce emissions related costs and waiting for the 'big fix' will not be sufficient. How allowances are initially allocated can have an important influence on the turn-over of capital and what types of technologies firms choose to invest in. The EU ETS provision that discontinues allowance allocation to existing facilities that retire creates a disincentive to retire dirty plants. This may be partially offset by the new unit set aside feature of the ETS. An updating approach to allocation could lead the industry to prefer lower emitting technologies and fuels and could be structured in a way that encourages renewables, but this set of incentives comes at the cost of reduced

    There is a paucity of evidence on the heterogeneous impacts of financial incentives on weight loss. Between March 2010 and January 2012, in a randomized controlled trial, we assigned 700 obese persons to three experimental arms. We test whether particular subgroups react differently to financial incentives for weight loss. Two treatment groups obtained a cash reward (€150 and €300 with 237 and 229 participants, respectively) for achieving an individually-assigned target weight within four months; the control group (234 participants) was not incentivized. Participants and administrators were not blinded to the intervention. We find that monetary rewards effectively induced obese individuals to reduce weight across all subgroups. However, there is no evidence for treatment-effect heterogeneity for those groups that were incentivized. Among those who were in the €300 group, statistically significant and large weight losses were observed for women, singles, and those who are not working (all above 4 kg in four months). In addition, the magnitude of the reward matters only for women and migrants. The effectiveness of financial incentives to reduce weight nevertheless raises sensitive ethical issues that should be taken into consideration by policymakers. Copyright © 2015 Elsevier Ltd.

    Physicians often experience difficulties in motivating patients with non-alcoholic fatty liver disease (NAFLD) to undergo lifestyle changes. The aim of this study is to examine whether 'Donations for Decreased alanine aminotransferase (ALT)' (D4D) prosocial behavior incentive can serve as an effective intrinsic motivational factor in comparison with conventional dietary and exercise intervention alone for NAFLD patients. Twenty-five NAFLD patients with elevated ALT were randomly assigned to a control group that received conventional dietary and exercise intervention alone, or a donation group whereby, as an incentive, we would make a monetary donation to the United Nations World Food Programme (WFP) based on the decrease in their ALT levels achieved over 12 weeks, in addition to receiving control intervention. In a donation group, we would donate US$1 to the WFP for every 1 IU/l of decrease in their ALT levels. There were no differences of pre-treatment clinical characteristics between the two groups. Significant reductions of ALT levels were achieved only in a donation group, although post-treatment ALT levels were not different between the two groups. These patients raised a total of $316 for the WFP. Promoting patients' intrinsic motivation by incorporating 'D4D' prosocial behavior incentive into conventional dietary and exercise intervention may provide a means to improve NAFLD. © The Author 2013.

    Properties of the subset of polygonal paths in the Hilbert space H of paths referring to a d-dimensional quantum-mechanical system are examined. Using the reproduction kernel technique we prove that each element of H is approximated by polygonal paths uniformly with respect to the ''norm'' of time-interval partitions. This result will be applied in the second part of the present paper to prove consistency of the uniform polygonal-path extension of the Feynman maps [ru

  20. Nonperturbative path integral expansion II

    International Nuclear Information System (INIS)

    Kaiser, H.J.

    1976-05-01

    The Feynman path integral representation of the 2-point function for a self-interacting Bose field is investigated using an expansion ('Path Integral Expansion', PIE) of the exponential of the kinetic term of the Lagrangian. This leads to a series - illustrated by a graph scheme - involving successively a coupling of more and more points of the lattice space commonly employed in the evaluation of path integrals. The values of the individual PIE graphs depend of course on the lattice constant. Two methods - Pade approximation and Borel-type extrapolation - are proposed to extract information about the continuum limit from a finite-order PIE. A more flexible PIE is possible by expanding besides the kinetic term a suitably chosen part of the interaction term too. In particular, if the co-expanded part is a mass term the calculation becomes only slightly more complicated than in the original formulation and the appearance of the graph scheme is unchanged. A significant reduction of the number of graphs and an improvement of the convergence of the PIE can be achieved by performing certain sums over an infinity of graph elements. (author)

  1. Distribution definition of path integrals

    International Nuclear Information System (INIS)

    Kerler, W.

    1979-01-01

    By starting from quantum mechanics it turns out that a rather general definition of quantum functional integrals can be given which is based on distribution theory. It applies also to curved space and provides clear rules for non-linear transformations. The refinements necessary in usual definitions of path integrals are pointed out. Since the quantum nature requires special care with time sequences, it is not the classical phase space which occurs in the phase-space form of the path integral. Feynman's configuration-space form only applies to a highly specialized situation, and therefore is not a very advantageous starting point for general investigations. It is shown that the commonly used substitutions of variables do not properly account for quantum effects. The relation to the traditional ordering problem is clarified. The distribution formulation has allowed to treat constrained systems directly at the quantum level, to complete the path integral formulation of the equivalence theorem, and to define functional integrals also for space translation after the transition to fields.

    Delivering compassionate and coordinated care is a goal for all health care providers. Humans are not always consistent, though, both individually and collectively, and this is why everyone needs incentives to be at their best and to try to always be improving. The endlessly interesting question in patient experience is, what should those incentives look like? Should they be financial or nonfinancial? Dr. Thomas H. Lee explores what is most effective in regard to engaging and motivating physicians. While different approaches will work in different organizational cultures, financial incentives have their role in performance improvement. Compassionate coordinated care should be a social norm and be pursued by all health care organizations.

    Employers seeking to motivate and encourage healthy behaviors among their employees are increasingly turning to incentive rewards. In fact, a recent Buck Consultants survey of 555 employers, titled Working Well: A Global Survey of Health Promotion and Workplace Wellness Strategies, predicts the use of such rewards to more than double over the next two to three years. This article provides an overview of the key considerations for employers seeking to maximize the value of incentive rewards. Discussion includes incentive strategies, types of rewards, reward amounts and regulatory considerations under the Health Insurance Portability and Accountability Act (HIPAA) and the Americans with Disabilities Act (ADA).

  5. Private long-term care insurance and state tax incentives.

    Stevenson, David G; Frank, Richard G; Tau, Jocelyn

    2009-01-01

    To increase the role of private insurance in financing long-term care, tax incentives for long-term care insurance have been implemented at both the federal and state levels. To date, there has been surprisingly little study of these initiatives. Using a panel of national data, we find that market take-up for long-term care insurance increased over the last decade, but state tax incentives were responsible for only a small portion of this growth. Ultimately, the modest ability of state tax incentives to lower premiums implies that they should be viewed as a small piece of the long-term care financing puzzle.

  6. Incentives for cogeneration in Italy: Logic and implementation

    International Nuclear Information System (INIS)

    Tomassetti, G.

    1992-01-01

    Within the framework of legal and financial incentives made possible through Italian legislation on cogeneration plants for on-site power generation, this paper reviews the planning criteria that went into the formulation of the incentives and the response obtained from small, medium and large industrial firms. The discussion takes into account the following aspects: the optimal timing of retrofits, national energy conservation and environmental policy objectives, energy surcharges, benefits to consumers as compared with those for energy producers, benefits from incentives as a function of cogeneration plant size, and the technical complexity of application requirements for prospective applicants

  7. Incentive, sustainable and fair pricing, a trilogy out of reach?

    The Water Framework Directive requires Member-States to implement by 2010 an incentive tariffication policy in order to ensure efficient use of water resources and compliance with environmental goals (good ecological status). But working out an incentive pricing system, that is both sustainable and fair, is not an easy task. 1) Can an incentive pricing be a sustainable pricing? a) Water & wastewater services are very capitalistic: fixed costs can represent up to 2/3 or 3/4 of the service cost...

    We address the contribution of financial incentives linked to pay for performance (P4P) to improving the quality of care. The situation of P4P is analyzed internationally and in the distinct health services in Spain. The participation of P4P in wage compensation and the effects of the current economic crisis on these incentives is discussed. We review the results of recent studies to clarify the role of these incentive models and assess possible orientations and new proposals. Copyright © 2011 SESPAS. Published by Elsevier Espana.

    2016-12-01

    We provide a theoretical framework to contribute to the current debate regarding the tendency of pharmaceutical companies to direct their R&D toward marketing products that are "follow-on" drugs of already existing drugs, rather than toward the development of breakthrough drugs. We construct a model with a population of patients who can be treated with drugs that are horizontally and vertically differentiated. In addition to a pioneering drug, a new drug can be marketed as the result of an innovative process. We analyze physician prescription choices and the optimal pricing decision of an innovative firm. We also characterize the incentives of the innovative firm to conduct R&D activities, disentangling the quest for breakthrough drugs from the firm effort to develop follow-on drugs. Our results offer theoretical support for the conventional wisdom that pharmaceutical firms devote too many resources to conducting R&D activities that lead to incremental innovations.

  10. Financial incentive schemes in primary care

    Full Text Available Stephen Gillam Department of Public Health and Primary Care, Institute of Public Health, University of Cambridge, Cambridge, UK Abstract: Pay-for-performance (P4P schemes have become increasingly common in primary care, and this article reviews their impact. It is based primarily on existing systematic reviews. The evidence suggests that P4P schemes can change health professionals' behavior and improve recorded disease management of those clinical processes that are incentivized. P4P may narrow inequalities in performance comparing deprived with nondeprived areas. However, such schemes have unintended consequences. Whether P4P improves the patient experience, the outcomes of care or population health is less clear. These practical uncertainties mirror the ethical concerns of many clinicians that a reductionist approach to managing markers of chronic disease runs counter to the humanitarian values of family practice. The variation in P4P schemes between countries reflects different historical and organizational contexts. With so much uncertainty regarding the effects of P4P, policy makers are well advised to proceed carefully with the implementation of such schemes until and unless clearer evidence for their cost–benefit emerges.

  11. Environmental perverse incentives in coastal monitoring.

    Science.gov (United States)

    Gibbs, Mark T

    2013-08-15

    It can be argued that the intensity of monitoring of coastal marine environments lags behind the equivalent terrestrial environments. This results in a paucity of long-term time series of key environmental parameters such as turbidity. This lack of management information of the sources and sinks, and causes and impacts of stressors to the coastal marine environment, along with a lack of co-ordination of information collection is compromising the ability of environmental impact assessments of major coastal developments to discriminate between local and remote anthropogenic impacts, and natural or background processes. In particular, the quasi outsourcing of the collection of coastal information can lead to a perverse incentive whereby in many cases nobody is actively or consistently monitoring the coastal marine environment effectively. This is particularly the case with regards to the collection of long-term and whole-of-system scale data. This lack of effective monitoring can act to incentivise poor environmental performance.

  12. Mitigating Inadvertent Insider Threats with Incentives

    Science.gov (United States)

    Liu, Debin; Wang, Xiaofeng; Camp, L. Jean

    Inadvertent insiders are trusted insiders who do not have malicious intent (as with malicious insiders) but do not responsibly managing security. The result is often enabling a malicious outsider to use the privileges of the inattentive insider to implement an insider attack. This risk is as old as conversion of a weak user password into root access, but the term inadvertent insider is recently coined to identify the link between the behavior and the vulnerability. In this paper, we propose to mitigate this threat using a novel risk budget mechanism that offers incentives to an insider to behave according to the risk posture set by the organization. We propose assigning an insider a risk budget, which is a specific allocation of risk points, allowing employees to take a finite number of risk-seeking choice. In this way, the employee can complete her tasks without subverting the security system, as with absolute prohibitions. In the end, the organization penalizes the insider if she fails to accomplish her task within the budget while rewards her in the presence of a surplus. Most importantly. the risk budget requires that the user make conscious visible choices to take electronic risks. We describe the theory behind the system, including specific work on the insider threats. We evaluated this approach using human-subject experiments, which demonstrate the effectiveness of our risk budget mechanism. We also present a game theoretic analysis of the mechanism.

  13. New Incentives to Stimulate Data Publication

    Science.gov (United States)

    Urban, E. R.; Lowry, R.; Pissierssens, P.

    2008-12-01

    Data from ocean observations and experiments often are not submitted to appropriate data centers, or if they are submitted, may not be easily retrievable. These problems arise for a variety of reasons. Data are not always submitted, even when required by the agency funding the research, because the rewards for submitting data are not strong enough. Once data are submitted, the typical data center disaggregates the data into its component parameters, so it is difficult to get all the data related to a particular experiment back out of the system. With the advent of persistent identifiers, like digital object identifiers , the rapid evolution of the high-speed Internet, and the availability of large digital storage capacities that enable the transfer and storage of comprehensive data sets, it is now possible to restructure data management in a way that will create new incentives for ocean scientists to submit their data, for others to use it, and for the originating scientists to get credit for their effort and creativity in collecting the data. This presentation will report on a new activity of the Scientific Committee on Oceanic Research and the International Ocean Data and Information Exchange of UNESCO's Intergovernmental Oceanographic Commission that is mapping out new ways to (1) submit the data underlying the figures and tables in traditionally published papers to a recognized repository and link it to the publication, and (2) stimulate the submission of data publications that can be cited on originating scientists' CVs.

  14. Investment incentives in the Korean electricity market

    Park, Jung-Yeon; Ahn, Nam-Sung; Yoon, Yong-Beum; Koh, Kyung-Ho; Bunn, Derek W.

    2007-01-01

    This paper develops a model-based analysis of the effects of various capacity incentive systems on new investment in the Korean electricity market. The restructuring process in Korea allocated power generation to six firms, competing within a wholesale market, albeit strictly on a cost basis. Because of this cost-based pool, capacity payments were also introduced to encourage new investment. However, it is an open question whether the current fixed capacity payment scheme is enough to secure resource adequacy, and consideration is being given to alternative mechanisms such as the use of LOLP. Using a detailed market simulation model, based on system dynamics, we compare these approaches in terms of how they may influence the investors' decisions and thereby determine the system reserve margin. The simulation results suggest that there may be serious problems in staying with the current fixed capacity payments in order to achieve resource adequacy. In contrast, an LOLP-based capacity mechanism may, in the longer term, increase the reserve margin compared with a fixed capacity payment. More generally, this paper indicates how crucial the effective modeling of the investment behavior of the independent power producers is for adequate policy support, even if they only constitute a fringe in a substantially centrally influenced market

  15. How unconventional gas prospers without tax incentives

    International Nuclear Information System (INIS)

    Kuuskraa, V.A.; Stevens, S.H.

    1995-01-01

    It was widely believed that the development of unconventional natural gas (coalbed methane, gas shales, and tight gas) would die once US Sec. 29 credits stopped. Quieter voices countered, and hoped, that technology advances would keep these large but difficult to produce gas resources alive and maybe even healthy. Sec. 29 tax credits for new unconventional gas development stopped at the end of 1992. Now, nearly three years later, who was right and what has happened? There is no doubt that Sec. 29 tax credits stimulated the development of coalbed methane, gas shales, and tight gas. What is less known is that the tax credits helped spawn and push into use an entire new set of exploration, completion, and production technologies founded on improved understanding of unconventional gas reservoirs. As set forth below, while the incentives inherent in Sec. 29 provided the spark, it has been the base of science and technology that has maintained the vitality of these gas sources. The paper discusses the current status; resource development; technology; unusual production, proven reserves, and well completions if coalbed methane, gas shales, and tight gas; and international aspects

  16. Hybrid carbon incentive mechanisms and political acceptability

    International Nuclear Information System (INIS)

    Vollebergh, H.R.J.; De Vries, J.L.; Koutstaal, P.R.

    1997-01-01

    In this paper it is analyzed how hybrid systems of carbon taxes and tradeable permits optimize some conflicting dimensions of political acceptability related to the design of these instruments. Pure systems like taxes without exemptions or auctioned tradeable permits cause problems for political acceptability in open economies due to high overall costs (abatement cost plus payments on the tax or auctions) for current polluters. Unfortunately, pure systems based on grandfathering of emission rights across the board do not provide a feasible alternative because of monitoring and enforcement problems. In contrast, consciously designed hybrid systems employ grandfathering of emission rights together with either carbon taxes or auctioned carbon permits in order to overcome acceptability problems of pure systems, while leaving incentives to reduce emissions at the margin untouched. Moreover, monitoring and enforcement costs of the hybrid systems are less due to the lower number of participating agents compared with the pure systems, while opportunities for cost- or burden-sharing exist as well. 3 figs., 4 tabs., 23 refs

    CLAUDIA ISAC

    2015-12-01

    Full Text Available The present paper aims to be an answer for many investors with financial powers, seeking financial instruments with yields above the average interest rate on the banking market. One such tool, fairly new to the Romanian banking market, has been implemented for about 14 years, and is becoming more and more an instrument for savings, investments or an aid in the purchase of a house. Regardless of the perspective presented in the table of contents, the incentive for choosing such a banking product is the state benefit, a form through which the administration creates the conditions necessary to update and develop the housing system. In the thesis I have explored aspects of legislation which, in such a short period of time have changed 3 times the amount and the method of granting the state benefit and I have also tried a quick historical and legislative evolution of the implementation of Bauspar system throughout Europe. It is pointed out that in comparison with other countries - namely Germany, England or Austria where this system is well-known and has been implemented for over 120 years - Romania is at the beginning of its journey, a fact proved especially by the number of signed contracts in relation to the number of inhabitants.

    2010-01-01

    An invaluable addition to the literature on UAV guidance and cooperative control, Cooperative Path Planning of Unmanned Aerial Vehicles is a dedicated, practical guide to computational path planning for UAVs. One of the key issues facing future development of UAVs is path planning: it is vital that swarm UAVs/ MAVs can cooperate together in a coordinated manner, obeying a pre-planned course but able to react to their environment by communicating and cooperating. An optimized path is necessary in order to ensure a UAV completes its mission efficiently, safely, and successfully. Focussing on the path planning of multiple UAVs for simultaneous arrival on target, Cooperative Path Planning of Unmanned Aerial Vehicles also offers coverage of path planners that are applicable to land, sea, or space-borne vehicles. Cooperative Path Planning of Unmanned Aerial Vehicles is authored by leading researchers from Cranfield University and provides an authoritative resource for researchers, academics and engineers working in...

    Reister, D.B.; Lenhart, S.M.

    1993-01-01

    Recent theoretical results have completely solved the problem of determining the minimum length path for a vehicle with a minimum turning radius moving from an initial configuration to a final configuration. Time optimal paths for a constant speed vehicle are a subset of the minimum length paths. This paper uses the Pontryagin maximum principle to find time optimal paths for a constant speed vehicle. The time optimal paths consist of sequences of axes of circles and straight lines. The maximum principle introduces concepts (dual variables, bang-bang solutions, singular solutions, and transversality conditions) that provide important insight into the nature of the time optimal paths. We explore the properties of the optimal paths and present some experimental results for a mobile robot following an optimal path.

    Tuberculosis (TB) is a serious public health concern, and Taiwan has implemented a pay-for-performance (P4P) program to incentivize healthcare professionals to provide comprehensive care to TB patients. This study aims to examine the effects of the TB P4P program on treatment outcomes and related expenses. A population-based natural experimental design with intervention and comparison groups. Propensity score matching was conducted to increase the comparability between the P4P and non-P4P group. A total of 12,018 subjects were included in the analysis, with 6009 cases in each group. Generalized linear models and multinomial logistic regression were employed to examine the effects of the P4P program. The regression models indicated that patients enrolled in the P4P program had 14% more ambulatory visits than non-P4P patients (P ratio, 1.56; P financial incentives to healthcare institutions could be a feasible model for better TB control.

    2013-04-15

    The Energy Efficiency Directive (2012/27/EU) includes provisions related to network tariffs and regulation. It is timely therefore to revisit the potential options for energy efficiency in grids, the treatment of energy efficiency in network tariffs and alternative policies for improving energy efficiency. This project builds on work done previously for the European Copper Institute in this area. In this paper, we concentrate on energy efficiency in electricity network design and operation. Other articles in the Directive relate to the role of the network tariffs and regulations in enabling or incentivising the provision of energy efficiency to end users. In section 2, we describe technical efficiency measures to reduce losses (improve energy efficiency) in the grid. Section 3 reviews grid tariffs in three countries to identify whether they provide incentives or disincentives for energy efficiency in the grid. Section 4 discusses and evaluates alternative regulations for energy efficiency in grids. Section 5 concludes and discusses the main components of the optimal policy framework.

    Full Text Available Environmental degradation threatens the long term resiliency of the US food and farming system. While USDA has provided conservation incentives for the adoption of best management practices (BMPs, only a small percentage of farms have participated in such conservation programs. This study uses conjoint analysis to examine Vermont farmers’ underlying preferences and willingness-to-accept (WTA incentives for three common BMPs. Based on the results of this survey, we hypothesize that federal cost share programs’ payments are below preferred incentive levels and that less familiar and more complex BMPs require a higher payment. Our implications focus on strategies to test these hypotheses and align incentive payments and other non-monetary options to increase BMP adoption.

  9. Financial incentives for healthy behavior: ethical safeguards for behavioral economics.

    Science.gov (United States)

    Lunze, Karsten; Paasche-Orlow, Michael K

    2013-06-01

    Economic incentives to promote healthy behavior are becoming increasingly common and have been suggested as an approach to decreasing healthcare costs. Ethical concerns about programs with such incentives are that they may contribute to inequities, be coercive, interfere with therapeutic relationships, undermine personal responsibility for health, and decrease social solidarity. Additionally, they may be a source of stigma or discrimination, promote dependence, and be unfair for those already engaged in targeted health behaviors or those who cannot fulfill the incentivized behaviors. Incentive programs need to incorporate appropriate safeguards to monitor these risks and support fairness in offering economic incentives to promote healthy behavior.

  5. Short-term incentive schemes for hospital managers

    Directory of Open Access Journals (Sweden)

    Lucas Malambe

    2013-10-01

    Full Text Available Orientation: Short-term incentives, considered to be an extrinsic motivation, are commonly used to motivate performance. This study explored hospital managers’ perceptions of short term incentives in maximising performance and retention. Research purpose: The study explored the experiences, views and perceptions of private hospital managers in South Africa regarding the use of short-term incentives to maximise performance and retention, as well as the applicability of the findings to public hospitals. Motivation for the study: Whilst there is an established link between performance reward schemes and organisational performance, there is little understanding of the effects of short term incentives on the performance and retention of hospital managers within the South African context. Research design, approach, and method: The study used a qualitative research design: interviews were conducted with a purposive sample of 19 hospital managers, and a thematic content analysis was performed. Main findings: Short-term incentives may not be the primary motivator for hospital managers, but they do play a critical role in sustaining motivation. Participants indicated that these schemes could also be applicable to public hospitals. Practical/managerial implications: Hospital managers are inclined to be more motivated by intrinsic than extrinsic factors. However, hospital managers (as middle managers also seem to be motivated by short-term incentives. A combination of intrinsic and extrinsic motivators should thus be used to maximise performance and retention. Contribution/value-add: Whilst the study sought to explore hospital managers’ perceptions of short-term incentives, it also found that an adequate balance between internal and external motivators is key to implementing an effective short-term incentive scheme.

  6. Incentive Mechanism of Micro-grid Project Development

    Directory of Open Access Journals (Sweden)

    Yong Long

    2018-01-01

    Full Text Available Due to the issue of cost and benefit, the investment demand and consumption demand of micro-grids are insufficient in the early stages, which makes all parties lack motivation to participate in the development of micro-grid projects and leads to the slow development of micro-grids. In order to promote the development of micro-grids, the corresponding incentive mechanism should be designed to motivate the development of micro-grid projects. Therefore, this paper builds a multi-stage incentive model of micro-grid project development involving government, grid corporation, energy supplier, equipment supplier, and the user in order to study the incentive problems of micro-grid project development. Through the solution and analysis of the model, this paper deduces the optimal subsidy of government and the optimal cooperation incentive of the energy supplier, and calculates the optimal pricing strategy of grid corporation and the energy supplier, and analyzes the influence of relevant factors on optimal subsidy and incentive. The study reveals that the cost and social benefit of micro-grid development have a positive impact on micro-grid subsidy, technical level and equipment quality of equipment supplier as well as the fact that government subsidies positively adjust the level of cooperation incentives and price incentives. In the end, the validity of the model is verified by numerical analysis, and the incentive strategy of each participant is analyzed. The research of this paper is of great significance to encourage project development of micro-grids and to promote the sustainable development of micro-grids.

  7. Incentives for industrial R&D: The Australian experience

    OpenAIRE

    1996-01-01

    The effects of Australian measures to influence investment in industrial R&D (IRD) are anafysed. Australian experience tends to suggest that, while selective schemes have performed a little better than a tax concession alone, the advantage to selectivity would look less pronounced if general incentives were extended at an appropriate rate to firms in tax loss. Even with relatively low inducement rates, such incentives appear to have the advantage, from an evolutionary perspective, of encourag...

    2004-01-01

    This paper provides a first study of the optimal design of active monitors' exit options in a problem involving a demand for liquidity and costly monitoring of the issuer. Optimal incentives to monitor the issuer may involve restricting the monitor's right to sell her claims on the firm's cash-flow early. But the monitor will then require a liquidity premium for holding such an illiquid claim. In general, therefore, there will be a trade off between incentives and liquidity. The paper highlig...

    This compact reference surveys the full range of available structural equation modeling (SEM) methodologies.  It reviews applications in a broad range of disciplines, particularly in the social sciences where many key concepts are not directly observable.  This is the first book to present SEM’s development in its proper historical context–essential to understanding the application, strengths and weaknesses of each particular method.  This book also surveys the emerging path and network approaches that complement and enhance SEM, and that will grow in importance in the near future.  SEM’s ability to accommodate unobservable theory constructs through latent variables is of significant importance to social scientists.  Latent variable theory and application are comprehensively explained, and methods are presented for extending their power, including guidelines for data preparation, sample size calculation, and the special treatment of Likert scale data.  Tables of software, methodologies and fit st...

  14. Analysis of Federal incentives used to stimulate energy production

    Energy Technology Data Exchange (ETDEWEB)

    1978-06-01

    Federal incentives for the development of solar energy are examined. A Federal incentive is any action that can be taken by the government to expand residential and commercial use of solar energy. The development of solar energy policy could be enhanced by identification, quantification, and analysis of Federal incentives that have been used to simulate the development of other forms of energy. The text of this report identifies, quantifies, and analyzes such incentives and relates them to current thought about solar energy. Four viewpoints used in this discussion come from 4 types of analysis: economic, political, organizational, and legal. The next chapter identifies actions (primarily domestic) that the Federal government has taken concerning energy. This analysis uses the typology of actions described in the previous chapter to identify actions, and the four viewpoints described there to determine whether an action concerns energy. Once identified, the actions are described and then quantified by an estimate of the 1976 cost of accomplishing them. Then incentives, investments, liabilities, regulations, and other factors are analyzed in detail for nuclear energy, hydroelectric power, coal, petroleum, and natural gas. Incentives of all energy sources are then discussed with respect to solar energy policy. (MCW)

    Purpose Policy makers are applying market-inspired competition and financial incentives to drive efficiency in healthcare. However, a lack of knowledge exists about the process whereby incentives are filtered through organizations to influence staff motivation, and the key role of managers is often overlooked. The purpose of this paper is to explore the strategies managers use as intermediaries between financial incentives and the individual motivation of staff. The authors use empirical data from a local case in Swedish specialized care. Design/methodology/approach The authors conducted an exploratory qualitative case study of a patient-choice reform, including financial incentives, in specialized orthopedics in Sweden. In total, 17 interviews were conducted with professionals in managerial positions, representing six healthcare providers. A hypo-deductive, thematic approach was used to analyze the data. Findings The results show that managers applied alignment strategies to make the incentive model motivating for staff. The managers' strategies are characterized by attempts to align external rewards with professional values based on their contextual and practical knowledge. Managers occasionally overruled the financial logic of the model to safeguard patient needs and expressed an interest in having a closer dialogue with policy makers about improvements. Originality/value Externally imposed incentives do not automatically motivate healthcare staff. Managers in healthcare play key roles as intermediaries by aligning external rewards with professional values. Managers' multiple perspectives on healthcare practices and professional culture can also be utilized to improve policy and as a source of knowledge in partnership with policy makers.

    1991-02-01

    The Nuclear Regulatory Commission (NRC) monitors incentive programs established by state regulators in order to obtain current information and to consider the potential safety effects of the incentive programs as applied to nuclear units. The current report is an update of NUREG/CR-5509, Incentive Regulation of Nuclear Power Plants by State Public Utility Commissions, published in December 1989. The information in this report was obtained from interviews conducted with each state regulator and each utility with a minimum entitlement of 10%. The agreements, orders, and settlements from which each incentive program was implemented were reviewed as required. The interviews and supporting documentation form the basis for the individual state reports describing the structure and financial impact of each incentive program. The programs currently in effect represent the adoption of an existing nuclear performance incentive program proposal and one new program. In addition, since 1989 a number of nuclear units have been included in one existing program; while one program was discontinued and another one concluded. 6 refs., 27 tabs

  17. Neural effects of positive and negative incentives during marijuana withdrawal.

    Directory of Open Access Journals (Sweden)

    Francesca M Filbey

    Full Text Available In spite of evidence suggesting two possible mechanisms related to drug-seeking behavior, namely reward-seeking and harm avoidance, much of the addiction literature has focused largely on positive incentivization mechanisms associated with addiction. In this study, we examined the contributing neural mechanisms of avoidance of an aversive state to drug-seeking behavior during marijuana withdrawal. To that end, marijuana users were scanned while performing the monetary incentive delay task in order to assess positive and negative incentive processes. The results showed a group x incentive interaction, such that marijuana users had greater response in areas that underlie reward processes during positive incentives while controls showed greater response in the same areas, but to negative incentives. Furthermore, a negative correlation between withdrawal symptoms and response in the amygdala during negative incentives was found in the marijuana users. These findings suggest that although marijuana users have greater reward sensitivity and less harm avoidance than controls, that attenuated amygdala response, an area that underlies fear and avoidance, was present in marijuana users with greater marijuana withdrawal symptoms. This is concordant with models of drug addiction that involve multiple sources of reinforcement in substance use disorders, and suggests the importance of strategies that focus on respective mechanisms.

    Hiram Phillips couldn't have been in better spirits. The CFO and chief administrative officer of Rainbarrel Products, a diversified consumer-durables manufacturer, Phillips felt he'd single-handedly turned the company's performance around. He'd only been at Rainbarrel a year, but the company's numbers had, according to his measures, already improved by leaps and bounds. Now the day had come for Hiram to share the positive results of his new performance management system with his colleagues. The corporate executive council was meeting, and even CEO Keith Randall was applauding the CFO's work: "Hiram's going to give us some very good news about cost reductions and operating efficiencies, all due to the changes he's designed and implemented this year." Everything looked positively rosy--until some questionable information began to trickle in from other meeting participants. It came to light, for instance, that R&D had developed a breakthrough product that was not being brought to market as quickly as it should have been--thanks to Hiram's inflexible budgeting process. Then, too, an employee survey showed that workers were demoralized. And customers were complaining about Rainbarrel's service. The general message? The new performance metrics and incentives had indeed been affecting overall performance--but not for the better. Should Rainbarrel revisit its approach to performance management? Commentators Stephen Kaufman, a senior lecturer at Harvard Business School; compensation consultant Steven Gross; retired U.S. Navy vice admiral and management consultant Diego Hernandez; and Barry Leskin, a consultant and former chief learning officer for Chevron Texaco, offer their advice in this fictional case study.

    Quantum mechanics is one of the most fascinating, and at the same time most controversial, branches of contemporary science. Disputes have accompanied this science since its birth and have not ceased to this day. Uncommon Paths in Quantum Physics allows the reader to contemplate deeply some ideas and methods that are seldom met in the contemporary literature. Instead of widespread recipes of mathematical physics, based on the solutions of integro-differential equations, the book follows logical and partly intuitional derivations of non-commutative algebra.

    Conclusion: The results of this study proved that the surprising incentive would improve the employees' safety performance just in the short term because the surprising value of the incentives dwindle over time. For this reason and to maintain the surprising value of the incentive system, the amount and types of incentives need to be evaluated and modified annually or biannually.

  6. Semi-classical approximation to path integrals - phases and catastrophes

    International Nuclear Information System (INIS)

    Levit, S.

    1977-01-01

    Problems of phases and catastrophes were encountered when trying to apply the classical S-matrix theory to the scattering phenomena in nuclear physics. The path integral formulation provided a suitable basis for the treatment of these and related problems. Within conventional mathematical language it was possible to give practical prescriptions and discuss their limitations. Since the semi-classical (stationary phase) approximation is commonly used in any application of the path integral method, the results are not restricted to the scattering problems and may be of general interest. The derivation of the uniform approximations in the energy representation should use the exact path integral expression as the starting point, rather than performing Fourier transforms on the expressions derived in the present lecture.

  7. Impact of repeated intravenous cocaine administration on incentive motivation depends on mode of drug delivery.

    Science.gov (United States)

    LeBlanc, Kimberly H; Maidment, Nigel T; Ostlund, Sean B

    2014-11-01

    The incentive sensitization theory of addiction posits that repeated exposure to drugs of abuse, like cocaine, can lead to long-term adaptations in the neural circuits that support motivated behavior, providing an account of pathological drug-seeking behavior. Although pre-clinical findings provide strong support for this theory, much remains unknown about the conditions that support incentive sensitization. The current study examined whether the mode of cocaine administration is an important factor governing that drug's long-term impact on behavior. Separate groups of rats were allowed either to self-administer intravenous cocaine or were given an equivalent number and distribution of unsignaled cocaine or saline infusions. During the subsequent test of incentive motivation (Pavlovian-to-instrumental transfer), we found that rats with a history of cocaine self-administration showed strong cue-evoked food seeking, in contrast to rats given unsignaled cocaine or saline. This finding indicates that the manner in which cocaine is administered can determine its lasting behavioral effects, suggesting that subjective experiences during drug use play a critical role in the addiction process. Our findings may therefore have important implications for the study and treatment of compulsive drug seeking. © 2013 Society for the Study of Addiction.

  8. Does a monetary incentive improve the response to a postal questionnaire in a randomised controlled trial? The MINT incentive study

    Directory of Open Access Journals (Sweden)

    Mt-Isa Shahrul

    2009-06-01

    Full Text Available Abstract Background Sending a monetary incentive with postal questionnaires has been found to improve the proportion of responders, in research in non-healthcare settings. However, there is little research on use of incentives to improve follow-up rates in clinical trials, and existing studies are inconclusive. We conducted a randomised trial among participants in the Managing Injuries of the Neck Trial (MINT to investigate the effects on the proportion of questionnaires returned and overall non-response of sending a £5 gift voucher with a follow-up questionnaire. Methods Participants in MINT were randomised to receive either: (a a £5 gift voucher (incentive group or (b no gift voucher (no incentive group, with their 4 month or 8 month follow-up questionnaire. We recorded, for each group, the number of questionnaires returned, the number returned without any chasing from the study office, the overall number of non-responders (after all chasing efforts by the study office, and the costs of following up each group. Results 2144 participants were randomised, 1070 to the incentive group and 1074 to the no incentive group. The proportion of questionnaires returned (RR 1.10 (95% CI 1.05, 1.16 and the proportion returned without chasing (RR 1.14 (95% CI 1.05, 1.24 were higher in the incentive group, and the overall non-response rate was lower (RR 0.68 (95% CI 0.53, 0.87. Adjustment for injury severity and hospital of recruitment to MINT made no difference to these results, and there were no differences in results between the 4-month and 8-month follow up questionnaires. Analysis of costs suggested a cost of £67.29 per additional questionnaire returned. Conclusion Monetary incentives may be an effective way to increase the proportion of postal questionnaires returned and minimise loss to follow-up in clinical trials.

  9. Welding Robot Collision-Free Path Optimization

    Directory of Open Access Journals (Sweden)

    Xuewu Wang

    2017-02-01

    Full Text Available Reasonable welding path has a significant impact on welding efficiency, and a collision-free path should be considered first in the process of welding robot path planning. The shortest path length is considered as an optimization objective, and obstacle avoidance is considered as the constraint condition in this paper. First, a grid method is used as a modeling method after the optimization objective is analyzed. For local collision-free path planning, an ant colony algorithm is selected as the search strategy. Then, to overcome the shortcomings of the ant colony algorithm, a secondary optimization is presented to improve the optimization performance. Finally, the particle swarm optimization algorithm is used to realize global path planning. Simulation results show that the desired welding path can be obtained based on the optimization strategy.

    Happell, Brenda; Palmer, Christine; Tennent, Rebeka

    2011-03-01

    To enhance the understanding of the skills and attitudes of mental health nurses working in the Australian Mental Health Nurse Incentive Program. The Mental Health Nurse Incentive Program places qualified mental health nurses alongside community-based general practitioners, private psychiatric practices and other appropriate organisations to provide clients with mental health conditions with a more integrated treatment plan. An exploratory, qualitative approach was undertaken, given the paucity of relevant research in this area. Exploratory individual interviews were conducted with ten mental health nurses working in this scheme. Data analysis was organised and managed using QSR NVivo qualitative analysis software. Respondents identified specific skills and attitudes required for practice under the Mental Health Nurse Incentive Program. Eight areas of skill and attitude were identified as essential for mental health nurses working in this field. This study highlights that many of these skills and attitudes are specific to the setting where mental health nurses are working. Mental health nurses working under this programme have a role to play in the dissemination of knowledge about their practice. More needs to be done by governments and other institutions to ensure that general practitioners and other health professionals understand the role played by mental health nurses in the provision of care. The extent to which the Mental Health Nurse Incentive Program becomes a sustainable strategy to promote quality and accessible mental health care will depend to some degree on the capacity to identify the skills and attitudes necessary for practice. The findings presented in this paper provide a significant contribution to articulating the essential characteristics required for this area of practice. © 2011 Blackwell Publishing Ltd.

  12. Investigating financial incentives for maternal health: an introduction.

    Science.gov (United States)

    Stanton, Mary Ellen; Higgs, Elizabeth S; Koblinsky, Marge

    2013-12-01

    Projection of current trends in maternal and neonatal mortality reduction shows that many countries will fall short of the UN Millennium Development Goal 4 and 5. Underutilization of maternal health services contributes to this poor progress toward reducing maternal and neonatal morbidity and mortality. Moreover, the quality of services continues to lag in many countries, with a negative effect on the health of women and their babies, including deterring women from seeking care. To enhance the use and provision of quality maternal care, countries and donors are increasingly using financial incentives. This paper introduces the JHPN Supplement, in which each paper reviews the evidence of the effectiveness of a specific financial incentive instrument with the aim of improving the use and quality of maternal healthcare and impact. The US Agency for International Development and the US National Institutes of Health convened a US Government Evidence Summit on Enhancing Provision and Use of Maternal Health Services through Financial Incentives on 24-25 April 2012 in Washington, DC. The Summit brought together leading global experts in finance, maternal health, and health systems from governments, academia, development organizations, and foundations to assess the evidence on whether financial incentives significantly and substantially increase provision, use and quality of maternal health services, and the contextual factors that impact the effectiveness of these incentives. Evidence review teams evaluated the multidisciplinary evidence of various financial mechanisms, including supply-side incentives (e.g. performance-based financing, user fees, and various insurance mechanisms) and demand-side incentives (e.g. conditional cash transfers, vouchers, user fee exemptions, and subsidies for care-seeking). At the Summit, the teams presented a synthesis of evidence and initial recommendations on practice, policy, and research for discussion. The Summit enabled structured

    2017-01-01

    ABSTRACT Background: Many established products (EPs – marketed for eight years or more) are widely used off-label despite little evidence on benefit–risk ratio. This exposes patients to risks related to safety and lack of efficacy, and healthcare providers to liability. Introducing new indications for EPs may represent a high societal value; however, manufacturers rarely invest in R&D for EPs. The objective of this research was to describe incentives and disincentives for developing new indications for EPs in Europe and to investigate consequences of current policies. Methods: Targeted literature search and expert panel meetings. Results: Within the current European-level and national-level regulatory framework there are limited incentives for development of new indications with EPs. Extension of indication normally does not allow the price to be increased or maintained, the market protection period to be extended, or exclusion from a reference price system. New indication frequently triggers re-evaluation, resulting in price erosion, regardless of the level of added value with the new indication. In consequence, manufacturers are more prone to undertake R&D efforts at early to mid-stage of product life cycle rather than with EPs, or to invest in new chemical entities, even in therapeutic areas with broad off-label use. This represents a potentially missed opportunity as developing new indications for EPs offers an alternative to off-label use or lengthy and expensive R&D for new therapies, opens new opportunities for potentially cost-effective treatment alternatives, as well as greater equity in patients’ access to treatment options. Conclusion: There are potential benefits from the development of new indications for EPs that are currently not being realized due to a lack of regulatory and pricing incentives in Europe. Incentives for orphan or paediatric drugs have proven to be effective in promoting R&D. Similarly, incentives to promote R&D in EPs should

  16. The response of maize production in Kenya to economic incentives

    Directory of Open Access Journals (Sweden)

    Onono, P.A.,

    2013-06-01

    Full Text Available Agricultural development policy in Kenya has emphasised the use of incentives towards increased production and therefore self-sufficiency in maize which is a basic staple for most households. The channels used to provide incentives to maize farmers over the years include setting higher producer prices; subsidisation of inputs; provision of agricultural credit, research and extension services; construction and maintenance of roads, development of irrigation and water systems; legislative, institutional and macroeconomic reforms. Despite these efforts outputof maize has remained below domestic requirements in most years and the country continues to rely on imports to meet the deficits. Studies have assessed the responsiveness of maize to output price and reported inelastic responses and have recommended policies targeting non-price incentives to complement prices for the required increased production of maize. The studies, however, did not analyse the influence of the non-price incentives on the production of the crop. The findings of those studies are therefore deficient in explaining the relative importance of different non-price incentives and how they complement prices in influencing maize production in Kenya. This study investigated the response of maize production to both price and non-price incentives. The aim of this study was to ascertain the relative importance of non-price factors in influencing production of the crops as well as complementarity between price and non-price incentives. The findings show that maize production responds positively to its output price, development expenditures in agriculture, maize sales to marketing boards, growth in per capita GDP, liberalisation and governance reforms. However, maize production responds negatively to fertiliser price and unfavourable weather conditions. The response of maize output to its price is lower with rising inflation and grain market liberalisation.

  17. What incentives influence employers to engage in workplace health interventions?

    2016-08-01

    Full Text Available Abstract Background To achieve a sustainable working life it is important to know more about what could encourage employers to increase the use of preventive and health promotive interventions. The objective of the study is to explore and describe the employer perspective regarding what incentives influence their use of preventive and health promotive workplace interventions. Method Semi-structured focus group interviews were carried out with 20 representatives from 19 employers across Sweden. The economic sectors represented were municipalities, government agencies, defence, educational, research, and development institutions, health care, manufacturing, agriculture and commercial services. The interviews were transcribed verbatim and the data were analysed using latent content analysis. Results Various incentives were identified in the analysis, namely: “law and provisions”, “consequences for the workplace”, “knowledge of worker health and workplace health interventions”, “characteristics of the intervention”, “communication and collaboration with the provider”. The incentives seemed to influence the decision-making in parallel with each other and were not only related to positive incentives for engaging in workplace health interventions, but also to disincentives. Conclusions This study suggests that the decision to engage in workplace health interventions was influenced by several incentives. There are those incentives that lead to a desire to engage in a workplace health intervention, others pertain to aspects more related to the intervention use, such as the characteristics of the employer, the provider and the intervention. It is important to take all incentives into consideration when trying to understand the decision-making process for workplace health interventions and to bridge the gap between what is produced through research and what is used in practice.

  18. Analysis of federal incentives used to stimulate energy consumption

    The purpose of the analysis is to identify and quantify Federal incentives that have increased the consumption of coal, oil, natural gas, and electricity. The introductory chapter is intended as a device for presenting the policy questions about the incentives that can be used to stimulate desired levels of energy development. In the theoretical chapter federal incentives were identified for the consumption of energy as Federal government actions whose major intent or result is to stimulate energy consumption. The stimulus comes through changing values of variables included in energy demand functions, thereby inducing energy consumers to move along the function in the direction of greater quantity of energy demanded, or through inducing a shift of the function to a position where more energy will be demanded at a given price. The demand variables fall into one of six categories: price of the energy form, price of complements, price of substitutes, preferences, income, and technology. The government can provide such incentives using six different policy instruments: taxation, disbursements, requirements, nontraditional services, traditional services, and market activity. The four major energy forms were examined. Six energy-consuming sectors were examined: residential, commercial, industrial, agricultural, transportation, and public. Two types of analyses of incentive actions are presented in this volume. The generic chapter focused on actions taken in 1978 across all energy forms. The subsequent chapters traced the patterns of incentive actions, energy form by energy form, from the beginning of the 20th century, to the present. The summary chapter includes the results of the previous chapters presented by energy form, incentive type, and user group. Finally, the implications of these results for solar policy are presented in the last chapter. (MCW)

    To achieve a sustainable working life it is important to know more about what could encourage employers to increase the use of preventive and health promotive interventions. The objective of the study is to explore and describe the employer perspective regarding what incentives influence their use of preventive and health promotive workplace interventions. Semi-structured focus group interviews were carried out with 20 representatives from 19 employers across Sweden. The economic sectors represented were municipalities, government agencies, defence, educational, research, and development institutions, health care, manufacturing, agriculture and commercial services. The interviews were transcribed verbatim and the data were analysed using latent content analysis. Various incentives were identified in the analysis, namely: "law and provisions", "consequences for the workplace", "knowledge of worker health and workplace health interventions", "characteristics of the intervention", "communication and collaboration with the provider". The incentives seemed to influence the decision-making in parallel with each other and were not only related to positive incentives for engaging in workplace health interventions, but also to disincentives. This study suggests that the decision to engage in workplace health interventions was influenced by several incentives. There are those incentives that lead to a desire to engage in a workplace health intervention, others pertain to aspects more related to the intervention use, such as the characteristics of the employer, the provider and the intervention. It is important to take all incentives into consideration when trying to understand the decision-making process for workplace health interventions and to bridge the gap between what is produced through research and what is used in practice.

    In its fee-for-service funding model for primary care, British Columbia, Canada, introduced incentive payments to general practitioners as pay for performance for providing enhanced, guidelines-based care to patients with chronic conditions. Evaluation of the program was conducted at the health care system level. To examine the impact of the incentive payments on annual health care costs and hospital utilization patterns in British Columbia. The study used Ministry of Health administrative data for Fiscal Year 2010-2011 for patients with diabetes, congestive heart failure, chronic obstructive pulmonary disease, and/or hypertension. In each disease group, cost and utilization were compared across patients who did, and did not, receive incentive-based care. Health care costs (eg, primary care, hospital) and utilization measures (eg, hospital days, readmissions). After controlling for patients' age, sex, service needs level, and continuity of care (defined as attachment to a general practice), the incentives reduced the net annual health care costs, in Canadian dollars, for patients with hypertension (by approximately Can$308 per patient), chronic obstructive pulmonary disease (by Can$496), and congestive heart failure (by Can$96), but not diabetes (incentives cost about Can$148 more per patient). The incentives were also associated with fewer hospital days, fewer admissions and readmissions, and shorter lengths of hospital stays for all 4 groups. Although the available literature on pay for performance shows mixed results, we showed that the funding model used in British Columbia using incentive payments for primary care might reduce health care costs and hospital utilization.

  1. Incentive Use in Research: Protecting Vulnerable Populations from Exploitation

    Full Text Available Global investment in Medical Research and Development has markedly increased in the last few decades. However, due to the decreasing public altruism, researchers have come under increased pressures from the funding bodies to produce results. Out of desperation, some researchers have resorted to using incentives as a means of sourcing for volunteers. Consequently, the research burden has disproportionately been shared among the most vulnerable populations in the society. Incentives especially monetary ones present an ethical dilemma because of the uncertainties’ surrounding the morality, amount and type of payment, vulnerability of volunteers and possible threats to voluntary participation. Several studies done on the use of incentives in medical research have noted that financial motivation was the number one reason for subjects to volunteer in Medical research. Mutual benefit and freedom of choice by participants were given as reasons to support their use. However, scientists who are against the use of incentives believe that they are coercive or undue inducements, and may influence a subjects’ ability to give an informed consent. Guidelines exist that protect vulnerable groups from exploitation, although none sheds light into the use of incentives. Nonetheless, in the face of the waning public altruism, the benefits of using incentives far outweigh the dangers, although researchers should avoid situations where their use may become problematic. As a mode of payment to research subjects, researchers should adopt a combination of the Dickerts’ Wage and re-imbursement models as guides in quantifying the incentive.

  2. Integrated assignment and path planning

    A surge of interest in unmanned systems has exposed many new and challenging research problems across many fields of engineering and mathematics. These systems have the potential of transforming our society by replacing dangerous and dirty jobs with networks of moving machines. This vision is fundamentally separate from the modern view of robotics in that sophisticated behavior is realizable not by increasing individual vehicle complexity, but instead through collaborative teaming that relies on collective perception, abstraction, decision making, and manipulation. Obvious examples where collective robotics will make an impact include planetary exploration, space structure assembly, remote and undersea mining, hazardous material handling and clean-up, and search and rescue. Nonetheless, the phenomenon driving this technology trend is the increasing reliance of the US military on unmanned vehicles, specifically, aircraft. Only a few years ago, following years of resistance to the use of unmanned systems, the military and civilian leadership in the United States reversed itself and have recently demonstrated surprisingly broad acceptance of increasingly pervasive use of unmanned platforms in defense surveillance, and even attack. However, as rapidly as unmanned systems have gained acceptance, the defense research community has discovered the technical pitfalls that lie ahead, especially for operating collective groups of unmanned platforms. A great deal of talent and energy has been devoted to solving these technical problems, which tend to fall into two categories: resource allocation of vehicles to objectives, and path planning of vehicle trajectories. An extensive amount of research has been conducted in each direction, yet, surprisingly, very little work has considered the integrated problem of assignment and path planning. This dissertation presents a framework for studying integrated assignment and path planning and then moves on to suggest an exact

    implementation. In addition to basing incentive design more on theory, there is a large literature discussing experiences with these schemes that can be used to draw out a number of lessons that can be learned and that could be used to influence or modify the design of incentive schemes. More rigorous study designs need to be used to account for the selection of physicians into incentive schemes. The use of instrumental variable techniques should be considered to assist with the identification of treatment effects in the presence of selection bias and other sources of unobserved heterogeneity. In randomised trials, care must be taken in using the correct unit of analysis and more attention should be paid to blinding. Studies should also examine the potential unintended consequences of incentive schemes by having a stronger theoretical basis, including a broader range of outcomes, and conducting more extensive subgroup analysis. Studies should more consistently describe i) the type of payment scheme at baseline or in the control group, ii) how payments to medical groups were used and distributed within the groups, and iii) the size of the new payments as a percentage of total revenue. Further research comparing the relative costs and effects of financial incentives with other behaviour change interventions is also required.

    The explanation of how and why firms succeed or fail is a recurrent research challenge. This is particularly important in the context of technological innovations. We focus on the role of historical events and decisions in explaining such success and failure. Using a case study of Nokia, we develop and extend a multi-layer path dependence framework. We identify four layers of path dependence: technical, strategic and leadership, organizational, and external collaboration. We show how path dep...

C-5 shows that k may have to be greater than the chromatic number. However, if the graph is connected, infinite and locally...... finite, and has finite chromatic number, then the k-coloring exists for every k >= chi(G). In fact, the k-coloring can be chosen such that every vertex is a starting vertex of an infinite path such that the color increases by 1 (mod k) along each edge. The method is based on the circular chromatic number...... chi(c)(G). In particular, we verify the above conjecture for all connected graphs whose circular chromatic number equals the chromatic number....

    In this work we explore the structure of the branching graph of the unitary group using Schur transitions. We find that these transitions suggest a new combinatorial expression for counting paths in the branching graph. This formula, which is valid for any rank of the unitary group, reproduces known asymptotic results. We proceed to establish the general validity of this expression by a formal proof. The form of this equation strongly hints towards a quantum generalization. Thus, we introduce a notion of quantum relative dimension and subject it to the appropriate consistency tests. This new quantity finds its natural environment in the context of RCFTs and fractional statistics; where the already established notion of quantum dimension has proven to be of great physical importance.

    The purpose of this study is to determine critical environmental parameters of soil K availability and to quantify those contributors by using a proposed path model. In this study, plot experiments were designed into different treatments, and soil samples were collected and further analyzed in laboratory to investigate soil properties influence on soil potassium forms (water soluble K, exchangeable K, non-exchangeable K). Furthermore, path analysis based on proposed path model was carried out to evaluate the relationship between potassium forms and soil properties. Research findings were achieved as followings. Firstly, key direct factors were soil S, ratio of sodium-potassium (Na/K), the chemical index of alteration (CIA), Soil Organic Matter in soil solution (SOM), Na and total nitrogen in soil solution (TN), and key indirect factors were Carbonate (CO3), Mg, pH, Na, S, and SOM. Secondly, path model can effectively determine direction and quantities of potassium status changes between Exchangeable potassium (eK), Non-exchangeable potassium (neK) and water-soluble potassium (wsK) under influences of specific environmental parameters. In reversible equilibrium state of , K balance state was inclined to be moved into β and χ directions in treatments of potassium shortage. However in reversible equilibrium of , K balance state was inclined to be moved into θ and λ directions in treatments of water shortage. Results showed that the proposed path model was able to quantitatively disclose moving direction of K status and quantify its equilibrium threshold. It provided a theoretical and practical basis for scientific and effective fertilization in agricultural plants growth. PMID:24204659

    Financial incentives are increasingly offered to recruit nursing personnel to work in underserved communities. The authors describe and compare the characteristics of federal, provincial and territorial financial recruitment incentive programs for registered nurses (RNs), nurse practitioners (NPs), licensed practical nurses (LPNs), registered practical nurses or registered psychiatric nurses. The authors identified incentive programs from government, health ministry and student aid websites and by contacting program officials. Only government-funded recruitment programs providing funding beyond the normal employee wages and benefits and requiring a service commitment were included. The authors excluded programs offered by hospitals, regional or private firms, and programs that rewarded retention. All provinces and territories except QC and NB offer financial recruitment incentive programs for RNs; six provinces (BC, AB, SK, ON, QC and NL) offer programs for NPs, and NL offers a program for LPNs. Programs include student loan forgiveness, tuition forgiveness, education bursaries, signing bonuses and relocation expenses. Programs target trainees, recent graduates and new hires. Funding and service requirements vary by program, and service requirements are not always commensurate with funding levels. This snapshot of government-funded recruitment incentives provides program managers with data to compare and improve nursing workforce recruitment initiatives. Copyright © 2015 Longwoods Publishing.

    Political as well as technological changes are now reshaping the electric utility industry. While accommodating these changes, state legislative and regulatory agencies have the opportunity to promote public policies. In this regard, various state entities are evaluating appropriate incentives for renewable energy development so as to introduce greater competition in electric generation. For example, the California legislature is considering a supplemental production payment and the State of Iowa has instituted a low-interest loan program for wind and other alternative energy generation. By complementing the existing federal tax incentives, state incentives can spur the wind industry`s growth. If structured in the wrong way, however, state assistance programs will undercut the value of the federal tax incentives. The federal anti-double dipping rules apply to certain state programs. If a developer utilizes the wrong type of state assistance for a wind project, the anti-double dipping rules will reduce the federal tax incentives and this in turn will decrease the project`s profitability. Rather than suffer these results, very few if any developer will use the state program. Despite the time and effort a state may expend to enact a program for alternative energy development, the state assistance will be ineffectual. This paper reviews the counterproductive results which state assistance can have on a wind project because of the federal anti-double dipping rules.

    The disparity between human resource in health and provision of health services is a growing concern worldwide. Many developing countries are facing this crisis and therefore human resource in health is considered a high priority on their agenda.This imbalance between supplies of human resource is exacerbated by migration of health workers in many countries. Understanding the motivational factor is an important aspect to retain the migrating health workforce. This paper analyses the role of financial and non financial incentives in motivating the health work force. A review of available literature was conducted to understand the role of motivational factor in retaining health workforce. A review of current literature found that an incentive plays a key role in motivating a health worker. Financial incentives are useful in improving the compliance to standard policies and procedures. Comprehensive integrated incentive system approach should be established to develop a sustainable health workforce with required skill. Likewise monetary incentives should be linked to adherence to provincial and national guidelines and procedures. Sustainability could be ensured by commitment of government, political will and involvement of key stakeholders and decision makers.

  12. Intermediaries in Trust: Indirect Reciprocity, Incentives, and Norms

    2015-01-01

    Full Text Available Any trust situation involves a certain amount of risk for trustors that trustees could abuse. In some cases, intermediaries exist who play a crucial role in the exchange by providing reputational information. To examine under what conditions intermediary opinion could have a positive impact on cooperation, we designed two experiments based on a modified version of the investment game where intermediaries rated the behaviour of trustees under various incentive schemes and different role structures. We found that intermediaries can increase trust if there is room for indirect reciprocity between the involved parties. We also found that the effect of monetary incentives and social norms cannot be clearly separable in these situations. If properly designed, monetary incentives for intermediaries can have a positive effect. On the one hand, when intermediary rewards are aligned with the trustor’s interest, investments and returns tend to increase. On the other hand, fixed monetary incentives perform less than any other incentive schemes and endogenous social norms in ensuring trust and fairness. These findings should make us reconsider the mantra of incentivization of social and public conventional policy.

    1999-01-01

    The object of the paper is to review theoretical and empirical contributions to the optimal management of risk selection incentives ('cream skimming') in health sector reforms. The trade-off between efficiency and risk selection is fostered in health sector reforms by the introduction of competitive mechanisms such as price competition or prospective payment systems. The effects of two main forms of competition in health sector reforms are observed when health insurance is mandatory: competition in the market for health insurance, and in the market for health services. Market and government failures contribute to the assessment of the different forms of risk selection employed by insurers and providers, as the effects of selection incentives on efficiency and their proposed remedies to reduce the impact of these perverse incentives. Two European (Netherlands and Spain) and two Latin American (Chile and Colombia) case studies of health sector reforms are examined in order to observe selection incentives, their effects on efficiency and costs in the health system, and regulation policies implemented in each country to mitigate incentives to 'cream skim' good risks.

  14. Blood donor incentives: A step forward or backward

    2010-01-01

    Full Text Available Dramatic increase in blood usage and critical seasonal blood shortages are faced by various countries. Countries which previously reached 100% voluntary nonremunerated donation have been led to offer different kinds of incentives to recruit blood donors and meet their blood demands. In some cases, these incentives are considered monetary and are in complete contrast with International standards like World Health Organization (WHO. It seems that attitudes toward sole dependency on nonremunerated voluntary blood donation have been changed in recent years and experts in some developed countries are reevaluating partial reliance on paid donation. On the other hand, besides the effects of such incentives on blood safety, several economic and psychological studies have shown that incentives have discouraging effects on pro-social behaviors like blood donation and will reduce the number of blood donors in long term. With regard to the results of such studies, it seems that implementing incentive-based blood donor recruitment programs to meet blood requirements by some countries is becoming a challenge for blood banks.

    Full Text Available This paper proposes a novel method to generate strategic team AI pathfinding plans for computer games and simulations using probabilistic pathfinding. This method is inspired by genetic algorithms (Russell and Norvig, 2002, in that, a fitness function is used to test the quality of the path plans. The method generates high-quality path plans by eliminating the low-quality ones. The path plans are generated by probabilistic pathfinding, and the elimination is done by a fitness test of the path plans. This path plan generation method has the ability to generate variation or different high-quality paths, which is desired for games to increase replay values. This work is an extension of our earlier work on team AI: probabilistic pathfinding (John et al., 2006. We explore ways to combine probabilistic pathfinding and genetic algorithm to create a new method to generate strategic team AI pathfinding plans.

    1990-01-01

    A geometrical interpretation of path integrals is developed in the space of trajectories. This yields a supersymmetric formulation of a generic path integral, with the supersymmetry resembling the BRST supersymmetry of a first class constrained system. If the classical equation of motion is a Killing vector field in the space of trajectories, the supersymmetry localizes the path integral to classical trajectories and the WKB approximation becomes exact. This can be viewed as a path integral generalization of the Duistermaat-Heckman theorem, which states the conditions for the exactness of the WKB approximation for integrals in a compact phase space.

    Some aspects of the path integral formulation of quantum mechanics are studied. This formalism is generalized to arbitrary canonical transformations, by means of an association between path integral probalility amplitudes and classical generators of transformations, analogous to the usual Hamiltonian time development phase space expression. Such association turns out to be equivalent to the Weyl quantization rule, and it is also shown that this formalism furnishes a path integral representation for a Lie algebra of a given set of classical generators. Some physical considerations about the path integral quantization procedure and about the relationship between classical and quantum dynamical structures are also discussed. (Author) [pt

  4. Nudge or not: can incentives change health behaviours?

    Science.gov (United States)

    Ries, Nola M

    2012-01-01

    The approach of "nudging" people toward healthier behaviours is currently in vogue, and user financial incentives (UFIs) are one possible nudge tool. Interesting debates arise as to the criteria UFIs must meet to qualify as a nudge. The more pressing issue, however, is to determine how UFIs can be structured and implemented to motivate and sustain health behaviour change. To date, Canadian public health strategies to promote physical activity and balanced nutrition focus mainly on information provision, with some product regulation measures and indirect financial incentives. Governments cannot afford direct UFI programs to incent all 60% of overweight and obese Canadians to reduce their body mass, but governments could consider UFIs targeted to specific risk groups where a shorter-term intervention could have long-term payoffs.

  6. Contract-Based Incentive Mechanism for Mobile Crowdsourcing Networks

    Directory of Open Access Journals (Sweden)

    2017-09-01

    Full Text Available Mobile crowdsourcing networks (MCNs are a promising method of data collecting and processing by leveraging the mobile devices’ sensing and computing capabilities. However, because of the selfish characteristics of the service provider (SP and mobile users (MUs, crowdsourcing participants only aim to maximize their own benefits. This paper investigates the incentive mechanism between the above two parties to create mutual benefits. By modeling MCNs as a labor market, a contract-based crowdsourcing model with moral hazard is proposed under the asymmetric information scenario. In order to incentivize the potential MUs to participate in crowdsourcing tasks, the optimization problem is formulated to maximize the SP’s utility by jointly examining the crowdsourcing participants’ risk preferences. The impact of crowdsourcing participants’ attitudes of risks on the incentive mechanism has been studied analytically and experimentally. Numerical simulation results demonstrate the effectiveness of the proposed contract design scheme for the crowdsourcing incentive.

    Zhang, Chuanming; Wang, Yang

    In project managing, the performance salary management mode is often used to motivate project managers and other similar staff to improve performance or reduce the cost. But the engineering activities who own a lot of internal and external uncertain factors can not be known by the principle. It is difficult for to develop a suitable incentive target to project managers etch. This paper thinks that the manager self master the maximum of information on engineering activities. So this paper sets up an incentive model: the project managers themselves report performance objectives; owner gives the managers reward or punishment combined with their reported performance and actual performance. The model to ensure that the project manager is only accurate self reported its results to get the maximum profit. At the same time, it cans incentive managers to improve performance or reduce the cost. This paper focuses on setting up the model, analyzing the model parameters. And cite an example analyze them.

    Full Text Available Mobile crowd sensing (MCS is a novel sensing paradigm which can sense human-centered daily activities and the surrounding environment. The impact of mobility and selfishness of participants on the data reliability cannot be ignored in most mobile crowd sensing systems. To address this issue, we present a universal system model based on the reverse auction framework and formulate the problem as the Multiple Quality Multiple User Selection (MQMUS problem. The quality-aware incentive mechanism (QAIM is proposed to meet the quality requirement of data reliability. We demonstrate that the proposed incentive mechanism achieves the properties of computational efficiency, individual rationality, and truthfulness. And meanwhile, we evaluate the performance and validate the theoretical properties of our incentive mechanism through extensive simulation experiments.

    This paper examines a self-enforced relational incentive contract between a risk neutral principal and a risk averse agent where the agent's human capital is essential in ex post realization of values. I analyse the effect of outside options on the optimal bonus level, showing how the presence of ex post outside options may impede desirable degrees of performance pay. The effect of risk aversion and incentive responsiveness is analysed by allowing for linear contracts. I show that the first order effect of these parameters are the same as in verifiable contracts, but second order effects show that the optimal bonus level's sensitivity to risk aversion and incentive responsiveness increases with the discount factor. The analysis has interesting implications on firm boundaries and specificity choices. (author)

    To simulate a market introduction of Intelligent Speed Adaptation (ISA) and to study the effect of a Pay as You Speed (PAYS) concept, a field trial with 153 drivers was conducted during 2007–2009. The participants drove under PAYS conditions for a shorter or a longer period. The PAYS concept......, with and without incentive crossed with informative ISA present or absent. The results showed that ISA is an efficient tool for reducing speeding particularly on rural roads. The analysis of speed data demonstrated that the proportion of distance driven above the speed where the ISA equipment responded (PDA...... level. Both informative ISA and incentive ISA reduced the PDA, but there was no statistically significant interaction. Informative reduced it more than the incentive....

  11. An incentive-based architecture for social recommendations

    We present an incentive-based architecture for providing recommendations in a social network. We maintain a distinct reputation system for each individual and we rely on users to identify appropriate correlations and rate the items using a system-provided recommendation language. The key idea is to design an incentive structure and a ranking system such that any inaccuracy in the recommendations implies the existence of a profitable arbitrage opportunity, hence making the system resistant to malicious spam and presentation bias. We also show that, under mild assumptions, our architecture provides users with incentive to minimize the Kullback-Leibler divergence between the ratings and the actual item qualities, quickly driving the system to an equilibrium state with accurate recommendations.

  12. Incentive salience attribution under reward uncertainty: A Pavlovian model.

    There is a vast literature on the behavioural effects of partial reinforcement in Pavlovian conditioning. Compared with animals receiving continuous reinforcement, partially rewarded animals typically show (a) a slower development of the conditioned response (CR) early in training and (b) a higher asymptotic level of the CR later in training. This phenomenon is known as the partial reinforcement acquisition effect (PRAE). Learning models of Pavlovian conditioning fail to account for it. In accordance with the incentive salience hypothesis, it is here argued that incentive motivation (or 'wanting') plays a more direct role in controlling behaviour than does learning, and reward uncertainty is shown to have an excitatory effect on incentive motivation. The psychological origin of that effect is discussed and a computational model integrating this new interpretation is developed. Many features of CRs under partial reinforcement emerge from this model. Copyright © 2014 Elsevier B.V. All rights reserved.

  13. Incentive schemes and female leadership in financial firms

    Full Text Available Our purpose is to explore how performance in Swedish financial companies is affected by the presence of a female chief executive officer (CEO, the presence of an incentive scheme, and the proportion of female board members. The results indicate that a female CEO is associated with a lower return on equity (ROE and a lower Tobin’s Q, but we find no significant association between the proportion of female board members and firm performance. An incentive scheme is generally associated with a lower return on assets (ROA and a higher Tobin’s Q. In particular, a share-based incentive scheme is associated with a lower ROA, a lower ROE, and a higher Tobin’s Q.

  14. CEOs´ monetary incentives and performance of Mexican firms

    Full Text Available This paper analyzes if changes in CEO remuneration and the execution of CEO stock options impact firm performance, under an emerging market context. Data is obtained from 88 non-financial companies listed in the Mexican Stock Exchange (2001-2012. A dynamic panel specification is employed, and regressions are run through the Generalized Method of Moments. Some evidence is found on the negative relationship between flat monetary incentives and Mexican firm performance, specifically for normal times. In addition, financial incentives based on results (particularly CEO stock options do not imply higher firm performance. Results suggest that companies in particular contexts should move towards the development of CEOs, more than promoting mostly monetary incentives for boosting firm performance. Companies operating in Mexico will gain from hiring intrinsically motivated CEOs, together with testing different extrinsic rewards (neither flat nor stock options in order to attain additive effects on intrinsic motivation.

    Motivation is probably one of the most important determinants for organizational performance, because it stimulates effort and effective behaviors among people in the organization. But what type of motivation should public managers rely on? The PSM literature has argued that public service...... motivation is the most important type of motivation in the delivery of public service, because it substitutes for egoistic motivation. Organizations whose members have high levels of PSM are therefore expected to be less dependent on utilitarian motivators such as monetary incentives. Motivation crowding...... theory, on the other hand, argues that the relationship is opposite, so it is the degree of incentives that affects motivation. Both arguments lead to expectations of an association between public service motivation and monetary incentives, but so far this complex relationship has not been entangled...

  18. Sellers' hedging incentives at EPA's emission trading auction

    Cason (1993) argued that the auction the EPA (Environmental Protection Agency in the USA) used in order to start the market for sulfur allowances, is not efficient. The set-up of the auction gives both buyers and sellers an incentive to understate their valuation of an allowance. In this paper, we show that the sellers' incentives are even more perverse than Cason suggested. In particular, we show that sellers have an incentive to set their ask price equal to zero, while simultaneously hedging their bets by submitting a positive bid. It is not possible to derive the Nash equilibrium for this set-up. If such an equilibrium exists, sellers either set only a positive ask price, or an ask price equal to zero, and a positive bid as well. 14 refs

    Before the new round of healthcare reform in China, primary healthcare providers could obtain a fixed 15 % or greater mark-up of profits by prescribing and selling medicines. There were concerns that this perverse incentive was a key cause of irrational medicine use. China's new Essential Medicines Program (EMP) was launched in 2009 as part of the national health sector reform initiatives. One of its core policies was to eliminate primary care providers' economic incentives to overprescribe or prescribe unnecessarily expensive drugs, which were regarded as consequences of China's traditional financing system for health institutions. The objective of the study was to measure changes in prescribing patterns in primary healthcare facilities after the removal of the economic incentives for physicians to overprescribe as a result of the implementation of the EMP. A comparison design was applied to 8,258 prescriptions in 2007 and 8,278 prescriptions in 2010, from 83 primary healthcare facilities nationwide. Indicators were adopted to evaluate medicine utilization, which included overall number of medicines, average number of Western and traditional Chinese medicines, pharmaceutical expenditure per outpatient prescription, and proportion of prescriptions that contained two or more antibiotics. We further assessed the use of medicines (antibiotics, infusion, hormones, and intravenous injection) per disease-specific prescription for hypertension, diabetes, coronary artery heart disease, bronchitis, upper respiratory tract infection, and gastritis. A difference-in-difference analysis was employed to evaluate the net policy effect. Overall changes in indicators were not found to be statistically significant between the 2 years. The results varied for different diseases. The number of Western drugs per outpatient prescription decreased while that of traditional Chinese medicines increased. Overuse of antibiotics remained an extensive problem in the treatment of many diseases

  20. The effect of policy incentives on electric vehicle adoption

    In order to increase the attractiveness of electric vehicles (EVs), packages of policy incentives are provided in many countries. However, it is still unclear how effective different policy incentives are. Also, it is questionable that they have the same impact on different groups of people. In this study, based on a stated-choice experiment, the effect of several potential policy incentives on EV-adoption, as well as the influence of socio-psychological determinants are investigated, using constructs of the Transtheoretical Model of Change (TTM) and the Protection Motivation Theory (PMT). The probability of stated EV-adoption increases if policy incentives are offered in the choice experiment, which is expected because of the decrease of the generalized cost of EV-use. The high stated valuation of free parking or access to bus lanes makes those incentives an efficient alternative to expensive subsidies. EV-adoption probability increases for people that are further in the process of behavioural change. However, the responsiveness to subsidies decreases for people in more advanced stages-of-change. People that believe EVs to be effective in decreasing the negative externalities of the current transport system and people whose travel patterns can cope with the use of EVs also have a higher probability to choose the EV. - Highlights: •Policy incentives have a positive influence on electric vehicle adoption. •Being in advanced stages-of-change to EV-adoption increases likelihood to adopt EVs. •People in more advanced stages-of-change to EV-adoption are less price-sensitive. •People with a high self-efficacy and response efficacy are more likely to adopt EVs.
