Headspace gas chromatography was used to determine the concentration of ethanol and methanol in blood samples from 519 individuals suspected of drinking and driving in Sweden where the legal alcohol limit is 0.50 mg/g in whole blood (11 mmol/l). The concentration of ethanol in blood ranged from 0.01 to 3.52 mg/g with a mean of 1.83 +/- 0.82 mg/g (+/- S.D.). The frequency distribution was symmetrical about the mean but deviated from normality. A plot of the same data on normal probability paper indicated that it might be composed of two subpopulations (bimodal). The concentration of methanol in the same blood specimens ranged from 1 to 23 mg/l with a mean of 7.3 +/- 3.6 mg/l (+/- S.D.) and this distribution was markedly skew (+). The concentration of ethanol (x) and methanol (y) were positively correlated (r = 0.47, P less than 0.001) and implies that 22% (r2) of the variance in blood-methanol can be attributed to its linear regression on blood-ethanol. The regression equation was y = 3.6 + 2.1 x and the standard error estimate was 0.32 mg/l. This large scatter precludes making reliable estimates of blood-methanol concentration from measurements of blood-ethanol concentration and the regression equation. But higher blood-methanol concentrations are definitely associated with higher blood-ethanol in this sample of Swedish drinking drivers. Frequent exposure to methanol and its toxic products of metabolism, formaldehyde and formic acid, might constitute an additional health risk associated with heavy drinking in predisposed individuals. The determination of methanol in blood of drinking drivers in addition to ethanol could indicate long-standing ethanol intoxication and therefore potential problem drinkers or alcoholics.  相似文献

As relationships between people and nature are being reassessed, not least as concerns about climate change gather increasing momentum, so a range of environmental and conservation themes are moving up public and political agendas. Rewilding, simply defined as increasing the role of natural processes within landscapes, is one such theme. This commentary paper outlines the variety of definitions and origins of the concept of rewilding, illustrates some of the elements of rewilding within Europe, and offers some general reflections on the rewilding process. The paper suggests that although many benefits have been claimed for moves to increase the role of natural processes within landscapes and environments, rewilding faces several challenges, in that it means different things to different people, public perceptions of rewilding can generate unease, hostility, and concern and it has only limited scientific support. At the same time, there is no clear statutory policies to guide the rewilding process. As such, rewilding organisations may increasingly look to communication and public relations to garner public and financial support for their cause.  相似文献

In September 2019, the U.K. House of Commons Environmental Audit Committee warned that the United Kingdom's food supply was vulnerable to climate change. Within the U.K. food retailing is highly concentrated with the four leading food retailers accounting for almost 70% of all food sales. In the face of the threat of climate change to food supplies, a focus on resilience might be seen to have much to offer retailers. However, little work has been published in the academic literature on if, and how, retailers are employing the concept of resilience in their business plans. With these thoughts in mind, this commentary paper provides an exploratory review of how the United Kingdom's four leading food retailers, namely Tesco, Sainsbury's, Asda, and Morrisons, have publicly acknowledged the importance of resilience in the face of climate change. The paper outlines definitions of resilience and retail resilience, draws out four general themes within the U.K. food retailers' resilience plans, and offers some wider reflections on the retailers' resilience plans in the face of climate change.  相似文献

There is increasing interest in how universities are governed, externally and internally (Austin and Jones 2016). Drawing on a comparative case study of the governance of six major Canadian universities and the literature, this article describes the impact of federal research and innovation policy and programs on universities and reflects on Ottawa's role. We suggest that the federal government participates in the external governance of universities, but in a way that differs significantly from provincial governments. Canadian federalism appears to be generally beneficial for university autonomy and examination of its operation sheds light on factors that enable universities to sustain their autonomy.  相似文献

Young adulthood represents a developmental period with disproportionately heightened risk of losing a job. Young adult unemployment has been linked to increased mental health problems, at least in the short term. However, their possible long-term impacts, often referred as “scarring effects,” have been understudied, possibly underestimating the magnitude of mental health burden that young adult unemployment generates. This longitudinal study examined whether duration of unemployment during young adulthood is associated with later mental health disorders, after accounting for mental and behavioral health problems in childhood. Furthermore, the current study investigated whether childhood neighborhood characteristics affect this association and if so, in what specific functional ways. Data were drawn from a longitudinal study of developmental outcomes in a community sample in Seattle. Data collection began in 1985 when study participants were elementary students and involved yearly assessments in childhood and adolescence (ages 10–16) and then biennial or triennial assessments (ages 18–39; N?=?677 at age 39; 47% European American, 26% African American, 22% Asian American, and 5% Native American; 49% female). The current study findings suggest that duration of unemployment across young adulthood increased mental health problems at age 39, regardless of gender. Childhood neighborhood characteristics, particularly their positive aspect, exerted independent impacts on adult mental health problems beyond unemployment experiences across young adulthood. The current findings indicate a needed shift in service profiles for unemployed young adults—a comprehensive approach that not only facilitates reemployment but also addresses mental health needs to help them to cope with job loss. Further, the present study findings suggest that childhood neighborhoods, particularly positive features such as positive neighborhood involvement, may represent concrete and malleable prevention targets that can curb mental health problems early in life.

Pay for performance (PFP) remains one of the most controversial policy debates in the New Public Management reform era. Skepticism about PFP in the public sector is often grounded in theories of public service motivation that suggest a misalignment between PFP's focus on extrinsic market‐based pay incentives and intrinsically motivated government workers. Frequently missing from this analysis, however, is any consideration for whether PFP leads to positive “sorting” effects on the composition of a government agency's workforce through attraction, selection, and attrition processes. Using data from two waves of the Schools and Staffing Survey, the authors examine whether PFP influences the sorting patterns of K–12 public schoolteachers across U.S. school districts. Findings show that, on average, school districts that adopted PFP secured new teacher hires who had graduated from colleges and universities with average SAT scores that were about 30 points higher than the new teacher cohorts hired by districts that did not adopt PFP.  相似文献

The ascendency of immigration as an issue in elections has been concomitant with massive increases in the Hispanic population in the U.S. We examine how immigration cues prompt greater or lesser levels of restrictionist sentiment among individuals, showing demographic context conditions the effect of candidates cues. Using data from the 2010 U.S. House elections, we illustrate cues presented in new destination states—states with massive increases in the size of the Hispanic population from 1990 to 2010—have a larger impact on individuals’ immigration preferences than cues presented in non-new destination contexts. We show candidates with more extreme immigration positions are more likely to prioritize the issue of immigration in their campaigns, suggesting campaign prioritization of immigration has a directional cue. We conclude these directional cues from Republican candidates in new destination contexts move individual attitudes toward restrictionist preferences.  相似文献
