Needs Driven Design Solutions In Railroad Projects

This presentation highlights state, federal, and railroad stakeholder coordination in a public-private partnership. The Indiana Gateway Project is a $71.4 million construction project underway in northwestern Indiana. This project will help Norfolk Southern and Amtrak address the single most delay-prone intercity rail passenger corridor in the country. The White River Freight Railroad Bridge Replacement by Indiana Railroad is a$14M project which replaced the 115-year old bridge with a 1,271-foot long bridge in Greene County, IN. The presentation also provides a brief summary of the project management oversight role HNTB Corporation assumed in both project teams as a consultant for the Indiana Department of Transportation

Lifting the veil of depression and alcoholism in sport coaching: how do we care for carers?

The purpose of this article is to explore the insights of an elite sport coach living with comorbid depression and alcohol misuse. Such consideration is necessary because as coaching is increasingly repositioned as a caring activity the wellbeing of coaches themselves has rarely been considered. To address this gap, a narrative analysis methodology and a story telling approach was used to present the experiences of a case study coach (Steve). The story is derived from Steve’s own perspective and the perspective of his wife, Jane. This novel multi-voiced approach reveals the complex interplay between the sporting environment, Steve’s depression and his alcohol-related problems. In doing so, Steve’s story makes an original contribution by unveiling the issue of mental health in elite sport coaching. Steve’s story depicts the significant impact of depressive symptoms, coupled by excessive alcohol use on a coach, their personal life and their career. Using the work of Goffman and Sartre, the story alludes to how such symptoms can be hidden, to greater and lesser extents, from professional colleagues. This is an important theoretical contribution, because to care for coaches, colleagues, employers and health professionals will need to understand the needs of individuals such as Steve. Developing an open and supportive culture, which accepts that coaches are fallible, may however be a challenge within professional sport contexts

Genetic and environmental influences on sleep quality in middle‐aged men: a twin study

Poor sleep quality is a risk factor for a number of cognitive and physiological age-related disorders. Identifying factors underlying sleep quality are important in understanding the etiology of these age-related health disorders. We investigated the extent to which genes and the environment contribute to subjective sleep quality in middle-aged male twins using the classical twin design. We used the Pittsburgh Sleep Quality Index to measure sleep quality in 1218 middle-aged twin men from the Vietnam Era Twin Study of Aging (mean age = 55.4 years; range 51-60; 339 monozygotic twin pairs, 257 dizygotic twin pairs, 26 unpaired twins). The mean PSQI global score was 5.6 [SD = 3.6; range 0-20]. Based on univariate twin models, 34% of variability in the global PSQI score was due to additive genetic effects (heritability) and 66% was attributed to individual-specific environmental factors. Common environment did not contribute to the variability. Similarly, the heritability of poor sleep-a dichotomous measure based on the cut-off of global PSQI>5-was 31%, with no contribution of the common environment. Heritability of six of the seven PSQI component scores (subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, and daytime dysfunction) ranged from 0.15 to 0.31, whereas no genetic influences contributed to the use of sleeping medication. Additive genetic influences contribute to approximately one-third of the variability of global subjective sleep quality. Our results in middle-aged men constitute a first step towards examination of the genetic relationship between sleep and other facets of aging.Accepted manuscrip

Quaternary paleoceanography of the central arctic based on Integrated Ocean Drilling Program Arctic Coring Expedition 302 foraminiferal assemblages

The Integrated Ocean Drilling Program (IODP) Arctic Coring Expedition (ACEX) Hole 4C from the Lomonosov Ridge in the central Arctic Ocean recovered a continuous 18 m record of Quaternary foraminifera yielding evidence for seasonally ice-free interglacials during the Matuyama, progressive development of large glacials during the mid-Pleistocene transition (MPT) �1.2–0.9 Ma, and the onset of high-amplitude 100-ka orbital cycles �500 ka. Foraminiferal preservation in sediments from the Arctic is influenced by primary (sea ice, organic input, and other environmental conditions) and secondary factors (syndepositional, long-term pore water dissolution). Taking these into account, the ACEX 4C record shows distinct maxima in agglutinated foraminiferal abundance corresponding to several interglacials and deglacials between marine isotope stages (MIS) 13–37, and although less precise dating is available for older sediments, these trends appear to continue through the Matuyama. The MPT is characterized by nearly barren intervals during major glacials (MIS 12, 16, and 22–24) and faunal turnover (MIS 12–24). Abundant calcareous planktonic (mainly Neogloboquadrina pachyderma sin.) and benthic foraminifers occur mainly in interglacial intervals during the Brunhes and very rarely in the Matuyama. A distinct faunal transition from calcareous to agglutinated foraminifers 200–300 ka in ACEX 4C is comparable to that found in Arctic sediments from the Lomonosov, Alpha, and Northwind ridges and the Morris Jesup Rise. Down-core disappearance of calcareous taxa is probably related to either reduced sea ice cover prior to the last few 100-ka cycles, pore water dissolution, or both

Constituting monetary conservatives via the 'savings habit': New Labour and the British housing market bubble

The ongoing world credit crunch might well kill off the most recent bubble dynamics in the British housing market by driving prices systematically downwards from their 2007 peak. Nonetheless, the experience of that bubble still warrants analytical attention. The Labour Government might not have been responsible for consciously creating it, but it has certainly grasped the opportunities the bubble has provided in an attempt to enforce a process of agential change at the heart of the British economy. The key issue in this respect is the way in which the Government has challenged the legitimacy of passive welfare receipts in favour of establishing a welfare system based on incorporating the individual into an active asset-holding society. The housing market has taken on new political significance as a means for individuals first to acquire assets and then to accumulate wealth on the back of asset ownership. The ensuing integration of the housing market into an increasingly reconfigured welfare system has permeated into the politics of everyday life. It has been consistent with individuals remaking their political subjectivities in line with preferences for the type of conservative monetary policies that typically keep house price bubbles inflated

The Prevalence and Clinical Implications of Comorbid Back Pain in Shoulder Instability: A Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability Cohort Study.

Background:Understanding predictors of pain is critical, as recent literature shows that comorbid back pain is an independent risk factor for worse functional and patient-reported outcomes (PROs) as well as increased opioid dependence after total joint arthroplasty. Purpose/Hypothesis:The purpose of this study was to evaluate whether comorbid back pain would be predictive of pain or self-reported instability symptoms at the time of stabilization surgery. We hypothesized that comorbid back pain will correlate with increased pain at the time of surgery as well as with worse scores on shoulder-related PRO measures. Study Design:Cross-sectional study; Level of evidence, 3. Methods:As part of the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability cohort, patients consented to participate in pre- and intraoperative data collection. Demographic characteristics, injury history, preoperative PRO scores, and radiologic and intraoperative findings were recorded for patients undergoing surgical shoulder stabilization. Patients were also asked, whether they had any back pain. Results:The study cohort consisted of 1001 patients (81% male; mean age, 24.1 years). Patients with comorbid back pain (158 patients; 15.8%) were significantly older (28.1 vs 23.4 years; P < .001) and were more likely to be female (25.3% vs 17.4%; P = .02) but did not differ in terms of either preoperative imaging or intraoperative findings. Patients with self-reported back pain had significantly worse preoperative pain and shoulder-related PRO scores (American Shoulder and Elbow Surgeons score, Western Ontario Shoulder Instability Index) (P < .001), more frequent depression (22.2% vs 8.3%; P < .001), poorer mental health status (worse scores for the RAND 36-Item Health Survey Mental Component Score, Iowa Quick Screen, and Personality Assessment Screener) (P < .01), and worse preoperative expectations (P < .01). Conclusion:Despite having similar physical findings, patients with comorbid back pain had more severe preoperative pain and self-reported symptoms of instability as well as more frequent depression and lower mental health scores. The combination of disproportionate shoulder pain, comorbid back pain and mental health conditions, and inferior preoperative expectations may affect not only the patient's preoperative state but also postoperative pain control and/or postoperative outcomes

Optical monitoring of polymerizations in droplets with high temporal dynamic range

The ability to optically monitor a chemical reaction and generate an in situ readout is an important enabling technology, with applications ranging from the monitoring of reactions in flow, to the critical assessment step for combinatorial screening, to mechanistic studies on single reactant and catalyst molecules. Ideally, such a method would be applicable to many polymers and not require only a specific monomer for readout. It should also be applicable if the reactions are carried out in microdroplet chemical reactors, which offer a route to massive scalability in combinatorial searches. We describe a convenient optical method for monitoring polymerization reactions, fluorescence polarization anisotropy monitoring, and show that it can be applied in a robotically generated microdroplet. Further, we compare our method to an established optical reaction monitoring scheme, the use of Aggregation-Induced Emission (AIE) dyes, and find the two monitoring schemes offer sensitivity to different temporal regimes of the polymerization, meaning that the combination of the two provides an increased temporal dynamic range. Anisotropy is sensitive at early times, suggesting it will be useful for detecting new polymerization “hits” in searches for new reactivity, while the AIE dye responds at longer times, suggesting it will be useful for detecting reactions capable of reaching higher molecular weights

When are breast cancer patients at highest risk of venous thromboembolism: a cohort study using English healthcare data

Breast cancer patients are at increased risk of VTE, particularly in the peri-diagnosis period. However, no previous epidemiological studies have investigated the relative impact of breast cancer treatments in a time-dependent manner. We aimed to determine the impact of breast cancer stage, biology and treatment on the absolute and relative risks of VTE, using several recently linked data sources from England. Our cohort comprised 13,202 breast cancer patients from the Clinical Practice Research Datalink (linked to Hospital Episode Statistics and Cancer Registry data), diagnosed between 1997 and 2006 with follow-up continuing to the end of 2010. Cox regression analysis was performed to determine which demographic, treatment-related and biological factors independently affected VTE risk. Women had an annual VTE incidence of 6% whilst receiving chemotherapy which was 10.8-fold higher (95% CI, 8.2 to 14.4; absolute risk (AR) =59.6 per 1000 person-years) than women who did not receive chemotherapy. Following surgery the risk was significantly raised in the first month (HR=2.2; 95% CI 1.4 to 3.4; AR=23.5; reference group, no surgery), but it was not raised subsequent to this. Risk of VTE was noticeably higher in the 3-months following initiation of Tamoxifen compared with the risk before therapy (HR=5.5; 95% CI 2.3 to 12.7; AR=24.1), however commencement of aromatase inhibitors was not associated with VTE (HR=0.8; 95% CI 0.5 to 1.4; AR=28.3). In conclusion, women receiving chemotherapy for breast cancer have a clinically important risk of VTE, whilst an increased risk of VTE immediately following endocrine therapy is restricted to Tamoxifen
