Impacts of hunter-gatherers on the vegetation history of the eastern vale of pickering, Yorkshire
No full textResearch is undertaken into the vegetation and human impact at three previously un-researched archaeological sites from the eastern Vale of Pickering. The vegetation history is reconstructed from the end of the Windermere Interstadial c. 13,000 (^14)C yr BP until the final Mesolithic c. 5100 (^14)C yr BP. The early Mesolithic human impact on the vegetation is assessed using a three stage statistical test to establish the internal variability in the data as well as background variations in pollen output. The results reveal that humans had a small but significant impact on the vegetation around two of the sites. Pollen preservation at the third site precluded analyses of the impacts of humans on the vegetation. The three-stage test used to test for human impact was quite successful but requires revision before any further use. On the whole the tests confirmed the findings of conventional human impact analyses. During the pre-Holocene fires occurred on a regular basis. These fires varied in location and intensity, suggesting that some of the fires were regional or large-scale, whilst others were small and very localized. A multi-causal explanation has been given for the fires. Later, during the early Mesolithic, human groups are thought to have burnt the reedswamp at the lake edges as part of an economic strategy. Star Carr is the only site that demonstrates clearance of significant areas of woodland. During the later Mesolithic the hunter-gatherers have a greater impact on the vegetation within the Vale. This is attributed to the need for more resources as a result of vegetation change and increased population levels. Unlike their counter-parts from the North York Moors, the occupants of the lowland Vale of Pickering cause no long-term change to their environment
Shifting and persosting in the face of failure: Learning from what did not work
No full textSocial justice activism demands coordinated, concentrated efforts to move the needle in a positive direction. In the author's nine years as a social justice educator, he led multiple large- and small-scale projects for social justice within higher education. In many ways, those efforts failed to create a lasting impact. In the higher education ecosystem, they also took away time from the kind of promotable work which would benefit his case for tenure and promotion. Trying - and failing - to effect institutional changes left him emotionally, psychologically, and physically exhausted. Beyond that, he suffered from feelings of loneliness, exclusion, and lack of direction. For a long time, the author blamed himself for the failure to change the institution to be a place in which he felt comfortable. He also failed to cope with these negative experiences and emotions, often seething in frustration or anger or avoiding similar situations of vulnerability or creativity. It took years for him to remember and internalize lessons of persistence and shifting appraisals in order to maintain motivation for action and survive the stressors of working within an oppressive system.Published versio
Production of lignin Pickering stabilizers using lignin samples from the acetone fractionation process
No full textColloidal lignin particles (CLPs) as stabilizers of
Pickering emulsions are a sustainable approach to replace
synthetic emulsifiers in cosmetic emulsions. In this work, the
effect of lignin samples from the acetone fractionation in the
production of CLPs for Pickering emulsion stabilization was
studied. The original samples and their fractions revealed
different structural features, reflected in the CLPs properties,
although, in general, all CLPs exhibited high potential as
Pickering stabilizers
Accidents at rural T-junctions
No full textThis report concerns traffic accidents occurring during the 5 years, 1979-1983, at a sample of some 300 T-junctions on rural single carriageway roads subject to a speed limit of 50 mile/h or higher and covering 40 English counties. The objectives of the study were to investigate the frequency and character of the accidents in relation to traffic flow, geometric layout and other factors, such as traffic speed and gradient. The study examined in particular, the safety performance of three design features, ghost islands, merging and diverging lanes, and islands in the minor road. The study examined not only those accidents occurring within 20 m of the T-junction (the 'Stats 19' definition of junction accidents) but also accidents up to 100 m from the junction. Multiple regression analysis was used to relate accident frequency at the junctions to a range of explanatory variables to provide a model for examining the effect of the geometric and other features.

Questions asked and answered in pilot and feasibility randomized controlled trials
No full textAbstract Background In the last decade several authors have reviewed the features of pilot and feasibility studies and advised on the issues that should be addressed within them. We extend this literature by examining published pilot/feasibility trials that incorporate random allocation, examining their stated objectives, results presented and conclusions drawn, and comparing drug and non-drug trials. Methods A search of EMBASE and MEDLINE databases for 2000 to 2009 revealed 3652 papers that met our search criteria. A random sample of 50 was selected for detailed review. Results Most of the papers focused on efficacy: those reporting drug trials additionally addressed safety/toxicity; while those reporting non-drug trials additionally addressed methodological issues. In only 56% (95% confidence intervals 41% to 70%) were methodological issues discussed in substantial depth, 18% (95% confidence interval 9% to 30%) discussed future trials and only 12% (95% confidence interval 5% to 24%) of authors were actually conducting one. Conclusions Despite recent advice on topics that can appropriately be described as pilot or feasibility studies the large majority of recently published papers where authors have described their trial as a pilot or addressing feasibility do not primarily address methodological issues preparatory to planning a subsequent study, and this is particularly so for papers reporting drug trials. Many journals remain willing to accept the pilot/feasibility designation for a trial, possibly as an indication of inconclusive results or lack of adequate sample size.</p
