Liverpool English.
Liverpool English (LE) is the variety of English spoken in Liverpool and much of the surrounding county of Merseyside, in the north-west of England. After London, the north-west of England is the most densely populated of all regions in England and Wales, with the population of Liverpool standing at around 450,000. LE itself is said to have developed in the middle of the 19th century, after rapid immigration from Ireland during the Irish potato famines of 1845–1847 (see Knowles 1973). Arguably as a result of this immigration, as we will see, there are some similarities between LE's phonological system and those of Irish Englishes. Of course, as we might expect, the phonological system of LE maintains its connection with other northern Englishes, too
HREC members\u27 personal values influence decision making in contentious cases
This article identifies 14 contentious issues faced by Human Research Ethics Committees (HRECs). The authors argue that HREC members will respond variably to these issues based on their own fundamental values and worldview. In particular, we propose that personal interpretations of current ethics regulations and HREC members’ attitudes to consequentialism, Kantianism, and utilitarianism in some cases affect their responses to contentious research issues. We seek to promote understanding of how personal and professional backÂgrounds of HREC reviewers influence their approaches to value-laden issues embedded in ethics applications. Taking the form of a literature review, our conÂtribution highlights the need for further exploration of how HREC members make decisions, and what factors influence the outcomes of ethics applications
A comprehensive, multi-process box-model approach to glacial-interglacial carbon cycling
The canonical question of which physical, chemical or biological mechanisms were responsible for oceanic uptake of atmospheric CO2 during the last glacial is yet unanswered. Insight from paleo proxies has led to a multitude of hypotheses but none so far have been convincingly supported in three dimensional numerical modelling experiments. The processes that influence the CO2 uptake and export production are inter-related and too complex to solve conceptually while complex numerical models are time consuming and expensive to run which severely limits the combinations of mechanisms that can be explored. Instead, an intermediate inverse box model approach is used here in which the whole parameter space is explored. The glacial circulation and biological production states are derived from these using proxies of glacial export production and the need to draw down CO2 into the ocean. We find that circulation patterns which explain glacial observations include reduced Antarctic Bottom Water formation and high latitude mixing and to a lesser extent reduced equatorial upwelling. The proposed mechanism of CO2 uptake by an increase of eddies in the Southern Ocean, leading to a reduced residual circulation, is not supported. Regarding biological mechanisms, an increase in the nutrient utilization in either the equatorial regions or the northern polar latitudes can reduce atmospheric CO2 and satisfy proxies of glacial export production. Consistent with previous studies, CO2 is drawn down more easily through increased productivity in the Antarctic region than the sub-Antarctic, but that violates observations of lower export production there
