Konferensbidrag (refereegranskat)abstract
- The second in a series of two, this paper presents the results from a comprehensive survey of the various interventions that the public sector could employ to increase the net social benefits of freight activity in metropolitan areas. In this paper, the strategies concerning: pricing, incentives, and taxation; logistical management; and freight demand/land use management are discussed along with an outline for identification of potential interventions that could be of use to address a given freight issue.

The New York city off-hour delivery program: A business and community-friendly sustainability program

- The New York City Off-Hour Delivery (NYC OHD) program is the work of a private-public-academic partnership - A collaborative effort of leading private-sector groups and companies, public-sector agencies led by the New York City Department of Transportation, and research partners led by Rensselaer Polytechnic Institute. The efforts of this partnership have induced more than 400 commercial establishments in NYC to accept OHD without supervision. The economic benefits are considerable: The carriers have reduced operational costs and parking fines by 45 percent; the receivers enjoy more reliable deliveries, enabling them to reduce inventory levels; the truck drivers have less stress, shorter work hours, and easier deliveries and parking; the delivery trucks produce 55-67 percent less emissions than they would during regular-hour deliveries, for a net reduction of 2.5 million tons of CO2 per year; and citizens' quality of life increases as a result of reduced conflicts between delivery trucks, cars, bicycles, and pedestrians, and through the use of low-noise delivery practices and technologies that minimize the impacts of noise. The total economic benefits exceed $20 million per year. The success of the OHD program is due largely to the policy design at its core, made possible with the behavioral microsimulation. This unique optimization-simulation system incorporates the research conducted into an operations research/management science tool that assesses the effectiveness of alternative policy designs. This enabled the successful implementation of the project within the most complex urban environment in the United States.

- In this work we employ technique of optically detected cyclotron resonance for evaluation of the role of localization processes in CdTe/CdMnTe and CdMnTe/CdMgTe quantum well structures. From microwave-induced changes of excitonic emissions we evaluate magnitude of potential fluctuations (Stokes shift), correlate optically detected cyclotron resonance results with the results of time-resolved experiments and discuss nature of recombination processes in the limit of a strong localization.

Is Parkinson's Disease Associated with Increased Mortality, Poorer Outcomes Scores, and Revision Risk After THA? Findings from the Swedish Hip Arthroplasty Register

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Neurological conditions such as Parkinson's disease are commonly accepted as a risk factor for an increased likelihood of undergoing revision surgery or death after THA. However, the available evidence for an association between Parkinson's disease and serious complications or poorer patient-reported outcomes after THA is limited and contradictory. QUESTIONS/PURPOSES: (1) Do patients with a preoperative diagnosis of Parkinson's disease have an increased risk of death after elective THA compared with a matched control group of patients? (2) After matching for patient- and surgery-related factors, do revision rates differ between the patients with Parkinson's disease and the matched control group? (3) Are there any differences in patient-reported outcome measures for patients with Parkinson's disease compared with the matched control group? METHODS: Data were derived from a merged database with information from the Swedish Hip Arthroplasty Register and administrative health databases. We identified all patients with Parkinson's disease who underwent THA for primary osteoarthritis between January 1, 1999 and December 31, 2012 (n = 490 after exclusion criteria applied). A control group was generated through exact one-to-one matching for age, sex, Charlson comorbidity index, surgical approach, and fixation method. Risk of death and revision were compared between the groups using Kaplan-Meier and log-rank testing. Patient-reported outcome measures (PROMs), routinely recorded as EQ-5D, EQ VAS, and pain VAS, were measured at the preoperative visit and at 1-year postoperatively; mean absolute values for PROM scores and change in scores over time were compared between the two groups. RESULTS: The risk of death did not differ at 90 days (control group risk = 0.61%; 95% CI = 0.00-1.3; Parkinson's disease group risk = 0.62%; 95% CI = 0.00-1.31; p = 0.998) or 1 year (control group = 2.11%; 95% CI = 0.81-3.39; Parkinson's disease group = 2.56%, 95% CI = 1.12-3.97; p = 0.670). At 9 years, the risk of death was increased for patients with Parkinson's disease (control group = 28.05%; 95% CI = 22.29-33.38; Parkinson's disease group = 54.35%; 95% CI = 46.72-60.88; p < 0.001). The risk of revision did not differ at 90 days (control group = 0.41%; 95% CI = 0.00-0.98; Parkinson's disease group = 1.03%; 95% CI = 0.13-1.92; p = 0.256). At 1 year, the risk of revision was higher for patients with Parkinson's disease (control group = 0.41%; 95% CI = 0.00-0.98; Parkinson's disease group = 2.10%; 95% CIs = 0.80-3.38; p = 0.021). This difference was more pronounced at 9 years (control group = 1.75%; 95% CI = 0.11-3.36; Parkinson's disease group = 5.44%; 95% CI = 2.89-7.91; p = 0.001) when using the Kaplan-Meier method. There was no difference between the control and Parkinson's disease groups for level of pain relief at 1 year postoperatively (mean reduction in pain VAS score for control group = 48.85, SD = 20.46; Parkinson's disease group = 47.18, SD = 23.96; p = 0.510). Mean change in scores for quality of life and overall health from preoperative measures to 1 year postoperatively were smaller for patients in the Parkinson's disease group compared with controls (mean change in EQ-5D scores for control group = 0.42, SD = 0.32; Parkinson's disease group = 0.30, SD = 0.37; p 0.003; mean change in EQ VAS scores for control group = 20.94, SD = 23.63; Parkinson's disease = 15.04, SD = 23.00; p = 0.027). CONCLUSIONS: Parkinson's disease is associated with an increased revision risk but not with short-term mortality rates relevant to assessing risk versus benefit before undergoing THR. The traditional reluctance to perform THR in patients with Parkinson's disease may be too conservative given that the higher long-term risk of death is more likely due to the progressive neurological disorder and not THR itself, and patients with Parkinson's disease report comparable outcomes to controls. Further research on outcomes in THR for patients with other neurological conditions is needed to better address the broader assumptions underlying this t aditional teaching.Level of Evidence Level III, therapeutic study.
