The functions of I think in political discourse

INTERNATIONAL JOURNAL OF APPLIED LINGUISTICS, Issue 1 2000
Anne-Marie Simon-Vandenbergen
The expression I (don't) think has in recent years received a fair amount of attention from different viewpoints and in different linguistic frameworks. After a brief survey of the most important literature on the subject, this article examines the occurrence of I think in political discourse as compared with its use in informal conversation. On the basis of two samples of 100 instances each from casual conversations and radio political interviews, the expression is looked at from the points of view of syntax, intonation, the semantics of the proposition, collocation, and the wider context of the interaction taking place. It is shown that the expression has a complex of meanings which cannot simply be labelled ,uncertainty'or ,lack of commitment'. Depending on the context, it can signal a tentative attitude or authoritative deliberation. It is further argued that an understanding of the extralinguistic situation and the cultural meaning of the genre, including the power and status of interactants, is essential if one wishes to interpret the selection of I think in individual instances.

Analysis of PV/wind potential in the Canadian residential sector through high-resolution building energy simulation

INTERNATIONAL JOURNAL OF ENERGY RESEARCH, Issue 4 2009
Ali M. Syed
Abstract Rising fuel prices and global warming are two major issues that concern people today. In this paper, the effect that the integration of the hybrid photovoltaic (PV)/wind-turbine generation can have on conservation of energy and reduction of greenhouse gases (GHGs) has been studied. Base-case energy demands were calculated using building energy simulation software and then the residential buildings were equipped with the PV/wind-turbine electricity generation devices. The results show that the integration of those equipments can reduce both cost of fuel and GHG emissions to a fair amount. Copyright © 2008 John Wiley & Sons, Ltd. [source]

The control of chlorophyll catabolism and the status of yellowing as a biomarker of leaf senescence

PLANT BIOLOGY, Issue 2008
H. Ougham
Abstract The pathway of chlorophyll catabolism during leaf senescence is known in a fair amount of biochemical and cell biological detail. In the last few years, genes encoding a number of the catabolic enzymes have been characterized, including the key ring-opening activities, phaeophorbide a oxygenase (PaO) and red chlorophyll catabolite reductase (RCCR). Recently, a gene that modulates disassembly of chlorophyll,protein complexes and activation of pigment ring-opening has been isolated by comparative mapping in monocot species, positional cloning exploiting rice genomics resources and functional testing in Arabidopsis. The corresponding gene in pea has been identified as Mendel's I locus (green/yellow cotyledons). Mutations in this and other chlorophyll catabolic genes have significant consequences, both for the course of leaf senescence and senescence-like stress responses, notably hypersensitivity to pathogen challenge. Loss of chlorophyll can occur via routes other than the PaO/RCCR pathway, resulting in changes that superficially resemble senescence. Such ,pseudosenescence' responses tend to be pathological rather than physiological and may differ from senescence in fundamental aspects of biochemistry and regulation. [source]

Evaluating measurement error in estimates of worker exposure assessed in parallel by personal and biological monitoring

AMERICAN JOURNAL OF INDUSTRIAL MEDICINE, Issue 2 2007
Elaine Symanski PhD
Abstract Background While studies indicate that the attenuating effects of imperfectly measured exposure can be substantial, they have not had the requisite data to compare methods of assessing exposure for the same individuals monitored over common time periods. Methods We examined measurement error in multiple exposure measures collected in parallel on 32 groups of workers. Random-effects models were applied under both compound symmetric and exponential correlation structures. Estimates of the within- and between-worker variances were used to contrast the attenuation bias in an exposure-response relationship that would be expected using an individual-based exposure assessment for different exposure measures on the basis of the intra-class correlation coefficient (ICC). Results ICC estimates ranged widely, indicative of a great deal of measurement error in some exposure measures while others contained very little. There was generally less attenuation in the biomarker data as compared to measurements obtained by personal sampling and, among biomarkers, for those with longer half-lives. The interval ICC estimates were oftentimes wide, suggesting a fair amount of imprecision in the point estimates. Ignoring serial correlation tended to over estimate the ICC values. Conclusions Although personal sampling results were typically characterized by more intra-individual variability than inter-individual variability when compared to biological measurements, both types of data provided examples of exposure measures fraught with error. Our results also indicated substantial imprecision in the estimates of exposure measurement error, suggesting that greater emphasis needs to be given to studies that collect sufficient data to better characterize the attenuating effects of an error-prone exposure measure.

On the Tasks of a Population Commission: A 1971 Statement by Donald Rumsfeld

POPULATION AND DEVELOPMENT REVIEW, Issue 3 2003
Article first published online: 20 APR 200
In its most familiar form, analytic assessment of the impact of demographic change on human affairs is the product of a decentralized cottage industry: individual scholars collecting information, thinking about its meaning, testing hypotheses, and publishing their findings. Guidance through the power of the purse and through institutional design that creates and sustains cooperating groups of researchers can impose some order and coherence on such spontaneous activity. But the sum total of the result may lack balance and leave important aspects of relevant issues inadequately explored. Even when research findings are picked up by the media and reach a broader public, the haphazardness of that process helps further to explain why the salience of population change to human welfare and its importance in public policymaking are poorly understood. The syndrome is not unique to the field of population, but the typically long time-lags with which aggregate population change affects economic and social phenomena make it particularly difficult for the topic to claim public attention. A time-tested, if less than fool-proof remedy is the periodic effort to orchestrate a systematic and thorough examination of the causes, consequences, and policy implications of demographic processes. Because the most potent frame for policymaking is the state, the logical primary locus for such stocktaking is at the country level. The Commission on Population Growth and the American Future was a uniquely ambitious enterprise of this sort. The Commission was established by the US Congress in 1970 as a result of a presidential initiative. Along with the work of two earlier British Royal Commissions on population, this US effort, mutatis mutandis, can serve as a model for in-depth examinations conducted at the national level anywhere. Chaired by John D. Rockefeller 3rd, the Commission submitted its final report to President Richard M. Nixon in March 1972. The background studies to the report were published in seven hefty volumes; an index to these volumes was published in 1975. Reproduced below is a statement to the Commission delivered on April 14, 1971 by Donald Rumsfeld, then Counsellor to President Nixon and in charge of the Office of Economic Opportunity. (Currently, Mr. Rumsfeld serves as US Secretary of Defense.) The brief statement articulates with great clarity the objectives of the Commission and the considerations that prompted them. The text originally appeared in Vol. 7 (pp. 1-3) of the Commission's background reports, which contains the statements at public hearings conducted by the Commission. National efforts toward comprehensive scientific reviews of population issues have their analogs at the international level. Especially notable on that score were the preparatory studies presented at the 1954 Rome and 1965 Belgrade world population conferences. The world population conferences that took place in Bucharest in 1974, in Mexico City in 1984, and in Cairo in 1994 were intergovernmental and political rather than scientific and technical meetings, but they also generated a fair amount of prior research. The year 2004 will break the decadal sequence of large-scale international meetings on population, and apart from the quadrennial congresses of the IUSSP, which showcase the voluntary research offerings of its members, none is being planned for the coming years. A partial substitute will be meetings organized by the UN's regional economic and social commissions. The first of these took place in 2002 for the Asia-Pacific region; the meetings for the other regions will be held in 2003-04. The analytic and technical contribution of these meetings, however, is expected to be at best modest. National efforts of the type carried out 30 years ago by the Commission on Population Growth and the American Future would be all the more salutary. [source]

Does the invisible hand have a green thumb?

THE GEOGRAPHICAL JOURNAL, Issue 1 2009
Incentives, linkages, the creation of wealth out of industrial waste in Victorian England
,Loop closing', that is, the creation of waste recycling linkages between different industries, has been hailed as a means of simultaneously achieving improved economic and environmental performance. As a result of the widespread assumption that traditional market incentives and institutions are not conducive to such an outcome, however, there remains a fair amount of scepticism as to what the capacity of business self-interest to promote this behaviour actually is. This article challenges the dominant negative perspective by discussing by-product development in one of the most market-oriented societies in human history, Victorian England. Building on nineteenth and early twentieth century writings on the topic, as well as a more detailed analysis of the development of valuable by-products from highly problematic iron and coal gas production residuals, a case is made that the search for increased profitability within the context of private property rights often simultaneously promoted economic and environmental progress in the long run, as well as on different geographical scales.
