William J. Harbison

Bill joined Sherrard & Roe after his retirement from the Tennessee Supreme Court in the spring of 1990. Although I didn\u27t appreciate it fully at the time, his arrival proved to be a defining event for our firm. To a group of practitioners in a growing law practice still trying to identify clearly our professional objectives and philosophy of practice, Justice Harbison served as an immediate and constant exemplar of those qualities and attributes that we most admired and that we knew should be perpetuated in our firm. Of course, we all knew before Bill Harbison joined our firm that he was no ordinary mortal. One of the qualities that made him unique was his ability to bring his superb intellectual talents to bear on a matter in the most quiet and unassuming way. His memory was legendary, and I must say that the passage of time had not diminished it. Bill could, and often did, recall cases by name and cite to them by book and page number, and it was clear that it had probably been months, or maybe even years, since he had read the case. Bill also possessed incomparable analytical skills, and he could slice through the most complicated problems and define concisely the con- trolling principle or issue involved. And in a wonderfully complementary way to these gifts of memory and analysis, Bill possessed a powerful intuition. Bill would often have a hunch about how a problem should be solved, and in every case I can remember his hunches were right. I remember remarking to Bill about his ability to exercise good judgment so consistently on so many kinds of problems, and in his self-effacing way he replied, Well, Tom, if it was good judgment, then it came from lots of experience, and that experience... well.., that came from bad judgment. From his first day with us, Bill Harbison was available to everyone in the firm. He was always ready to talk, prepared to interrupt whatever he was doing, and he welcomed everyone to come and sit with him. His interest in others was genuine, and he was open and warm to all ideas. Very soon he became a mentor and positive re- source to the younger lawyers in the firm

Perceived Impacts of International Service on Volunteers: Interim Results From a Quasi-Experimental Study

There is growing interest in the potential of international service to foster international understanding between peoples and nations and to promote global citizenship and intercultural cooperation, and international service may be growing in prevalence worldwide. Despite the scale of international service, its impacts are not well understood. Although there is a growing body of descriptive evidence about the various models and intended outcomes of international service, the overwhelming majority of research is based on case and cross-sectional studies, which do not permit conclusions about the impacts of international service. This paper reports on a quasi-experimental study that assesses perceptions of the impact of service on international volunteers, matched to a comparison group that did not volunteer internationally during the same study period. The results of this quasi-experimental study suggest that international volunteer service has a positive impact on international volunteers’ perceived international awareness, international social capital, and international career intentions. However, compared to the non-participants, results suggest that international service does not have an impact on volunteers’ perceived intercultural relations. In addition, several variables are found to influence specific outcomes

Abiotic and biotic factors associated with tick population dynamics on a mammalian host: Ixodes hexagonus infesting otters, lutra iutra

The Eurasian otter, Lutra lutra, hosts several parasites with zoonotic potential. As this semiaquatic mammal has large ranges across terrestrial, freshwater and marine habitats, it has the capacity for wide dispersion of pathogens. Despite this, parasites of otters have received relatively little attention. Here, we examine their ectoparasite load and assess whether this is influenced by abiotic or biotic variables. Climatic phenomena such as the North Atlantic Oscillation (NAO) affect weather conditions in northern Europe. Consequently parasite distributions, particularly species with life stages exposed to the external environment, can be affected. We assessed the extent to which inter-annual variations in large-scale weather patterns (specifically the NAO and Central England (CE) temperatures) and host characteristics influenced tick prevalence and intensity. Ectoparasites consisted of a single species, the nidiculous tick Ixodes hexagonus (prevalence  = 24.3%; mean intensity  = 7.2; range  = 1–122; on n  = 820 otter hosts). The prevalence, but not intensity of infestation, was associated with high CE temperatures, while both prevalence and intensity were associated with positive phases of the NAO. Such associations indicate that I. hexagonus are most abundant when weather conditions are warmer and wetter. Ticks were more prevalent on juvenile than sub-adult or adult otters, which probably reflects the length of time the hosts spend in the holt where these ticks quest. High tick number was associated with poor host condition, so either poor condition hosts are more susceptible to ticks, or tick infestations negatively impact on host condition. Otters are clearly an important and common host for I. hexagonus, which has implications for vector-borne diseases. This work is the first to consider the impacts of long-term weather patterns on I. hexagonus and uses wild-animal cadavers to illustrate the importance of abiotic and biotic pressures impacting parasitic populations

Seroprevalence of rubella antibodies and determinants of susceptibility to rubella in a cohort of pregnant women in Canada, 2008–2011

Long term control of rubella and congenital rubella syndrome relies on high population-level immunity against rubella, particularly among women of childbearing age. In Canada, all pregnant women should be screened so that susceptible new mothers can be offered vaccination for rubella before discharge. This study was undertaken to estimate rubella susceptibility in a cohort of pregnant women in Canada and to identify associated socio-economic and demographic factors. Biobanked plasma samples were obtained from the Maternal-Infant Research on Environmental Chemicals (MIREC) study, in which pregnant women were recruited between 2008 and 2011. Socio-demographic characteristics and obstetric histories were collected. Second trimester plasma samples (n = 1,752) were tested for rubella-specific IgG using an in-house enzyme-linked immunosorbent assay. The percentage of women with IgG titers <5 IU/mL, 5–10 IU/mL, and 10 IU/mL were 2.3%, 10.1%, and 87.6%, respectively. Rates of seronegativity, defined as <5 IU/mL, were 3.1% in women who had no previous live birth and 1.6% in women who had given birth previously. Among the latter group, seronegativity was higher in women with high school education or less (adjusted OR (aOR) 5.93, 95% CI 2.08–16.96) or with a college or trade school diploma (aOR 3.82, 95% CI 1.45–10.12), compared to university graduates, and those born outside Canada (aOR 2.60, 95% CI 1.07–6.31). In conclusion, a large majority of pregnant women were found to be immune to rubella. Further research is needed to understand inequalities in vaccine uptake or access, and more effort is needed to promote catch-up measles-mumps-rubella vaccination among socioeconomically disadvantaged and immigrant women of childbearing age

An analysis of Australia's carbon pollution reduction scheme

The authors review the decision-making since the Labour Government came into office (November 2007). The Australian Government’s ‘Carbon Pollution Reduction Scheme’ White Paper (15 December 2008) proposes that an Australian Emissions Trading Scheme (AETS) be implemented in mid-2010. Acknowledging that the scheme is comprehensive, the paper finds that in many cases, Australia will take a softer approach to climate change through the AETS than the European Union ETS(EUETS). The paper assesses key issues in the White Paper such as emissions reduction targets, GHG coverage, sectoral coverage, inclusion of unlimited quantities of offsets from Kyoto international markets and exclusion of deforestation activities

Vascular access survival and incidence of revisions: A comparison of prosthetic grafts, simple autogenous fistulas, and venous transposition fistulas from the United States Renal Data System Dialysis Morbidity and Mortality Study

AbstractObjective: The study's aim was to evaluate access patency and incidence of revisions in patients initiating hemodialysis and to determine differences in access performance by type of access among patient subgroups. Methods: The study used data from the United States Renal Data System Dialysis Morbidity and Mortality Study Wave 2, which contained a random sample of dialysis patients initiating dialysis in 1996 and early 1997. Failures and revisions were evaluated among 2247 newly placed hemodialysis accesses by using Cox proportional hazards regression model and Poisson regression. Primary and secondary patency rates were estimated using the Kaplan-Meier method. Results: Fifteen hundred seventy-four prosthetic grafts, 492 simple autogenous fistulas, and 181 venous transposition fistulas were available for evaluation. Prosthetic grafts had a 41% greater risk of primary failure compared with simple fistulas (relative risk, 1.41; 95% CI, 1.22-1.64; P <.001) and a 91% higher incidence of revision (relative risk, 1.91; 95% CI, 1.60-2.28; P <.001). At 2 years, autogenous fistulas demonstrated superior primary patency (39.8% versus 24.6%, P <.001) and equivalent secondary patency (64.3% versus 59.5%, P =.24) compared with prosthetic grafts. When compared with simple fistulas, vein transpositions demonstrated equivalent secondary patency at 2 years (61.5% versus 64.3%, P =.43) but inferior primary patency (27.7% versus 39.8%, P =.008) and had a 32% increased incidence of revision (P =.04). Autogenous fistulas had superior primary patency compared with prosthetic grafts in all patient subgroups except for patients with previously failed access. Vein transpositions showed the greatest benefit in terms of patency and incidence of revision in women and in patients with previously failed access. Conclusions: The preferential placement of autogenous fistulas may increase primary patency and decrease the incidence of revisions. Vein transpositions had similar secondary patency compared with simple fistulas, but required more revisions. The greatest benefit of a vein transposition fistula was seen in women and in patients with a history of access failure. (J Vasc Surg 2001;34:694-700.
