Little Resemblance (little + resemblance)
Selected AbstractsCharacteristics and dynamics of multiple intertidal bars, north Lincolnshire, EnglandEARTH SURFACE PROCESSES AND LANDFORMS, Issue 4 2006Selma van Houwelingen Abstract Multiple intertidal bars and troughs, often referred to as ,ridges and runnels', are significant features on many macrotidal sandy beaches. Along the coastline of England and Wales, they are particularly prevalent in the vicinity of estuaries, where the nearshore gradient is gentle and a large surplus of sediment is generally present. This paper examines the dynamics of such bar systems along the north Lincolnshire coast. A digital elevation model of the intertidal morphology obtained using LIDAR demonstrates that three to five intertidal bars are consistently present with a spacing of approximately 100 m. The largest and most pronounced bars (height = 0·5,0·8 m) are found around mean sea level, whereas the least developed bars (height = 0·2,0·5 m) occur in the lower intertidal zone. Annual aerial photographs of the intertidal bar morphology were inspected to try to track individual bars from year to year to derive bar migration rates; however, there is little resemblance between concurrent photographs, and ,resetting' of the intertidal profile occurs on an annual basis. Three-dimensional beach surveys were conducted monthly at three locations along the north Lincolnshire coast over a one-year period. The intertidal bar morphology responds strongly to the seasonal variation in the forcing conditions, and bars are least numerous and flattest during the more energetic winter months. Morphological changes over the monthly time scale are strongly affected by longshore sediment transport processes and the intertidal bar morphology can migrate along the beach at rates of up to 30 m per month. The behaviour of intertidal bars is complex and varies over a range of spatial and temporal scales in response to a combination of forcing factors (e.g. incident wave energy, different types of wave processes, longshore and cross-shore sediment transport), relaxation time and morphodynamic feedback.

Doeschl-Wilson Abstract A. B. Murray and C. Paola (1994, Nature, vol. 371, pp. 54,57; 1997, Earth Surface Processes and Landforms, vol. 22, pp. 1001,1025) proposed a cellular model for braided river dynamics as an exploratory device for investigating the conditions necessary for the occurrence of braiding. The model reproduces a number of the general morphological and dynamic features of braided rivers in a simplified form. Here we test the representation of braided channel morphodynamics in the Murray,Paola model against the known characteristics (mainly from a sequence of high resolution digital elevation models) of a physical model of a braided stream. The overall aim is to further the goals of the exploratory modelling approach by first investigating the capabilities and limitations of the existing model and then by proposing modifications and alternative approaches to modelling of the essential features of braiding. The model confirms the general inferences of Murray and Paola (1997) about model performance. However, the modelled evolution shows little resemblance to the real evolution of the small-scale laboratory river, although this depends to some extent on the coarseness of the grid used in the model relative to the scale of the topography. The model does not reproduce the bar-scale topography and dynamics even when the grid scale and amplitude of topography are adapted to be equivalent to the original Murray,Paola results. Strong dependence of the modelled processes on local bed slopes and the tendency for the model to adopt its own intrinsic scale, rather than adapt to the scale of the pre-existing topography, appear to be the main causes of the differences between numerical model results and the physical model morphology and dynamics. The model performance can be improved by modification of the model equations to more closely represent the water surface but as an exploratory approach hierarchical modelling promises greater success in overcoming the identified shortcomings.

BURGESS abstract The argument from potential has been hard to assess because the versions presented by friends and those presented by enemies have born very little resemblance to each other. I here try to improve this situation by attempting to bring both versions into enforced contact. To this end, I sketch a more detailed analysis of the modern concept of potential than any hitherto attempted. As one would expect, arguments from potential couched in terms of that notion are evident non-starters. I then ask how the modern notion of potential needs to be supplemented in order to produce a more convincing argument. I then enquire whether the supplementations utilised in the most distinguished recent presentations of the argument have anything better than an ad hoc role to play in contemporary metaphysics. I conclude that the rehabilitation of the argument is unlikely; in any event, the onus of proof seems to be on the friend of that argument to show that it is uncontrived. Finally, I argue that the (modern) notion of potential has an important role to play in any plausible account of foetal value. [source] Bounded Choices: Somali Women Constructing Difference in Minnesota HousingJOURNAL OF INTERIOR DESIGN, Issue 2 2007Tasoulla Hadjiyanni ABSTRACT Coming to Minnesota to escape a devastating war, Somali refugees found themselves living in rental units that had little resemblance to the dwellings they left behind. Interviews with eight Somali women in their Minnesota homes reveal the difficult choices they had to make in order to preserve Somali cultural traditions and practices amidst strong American influences. As a way to construct the Somali sense of difference, women appropriated their living environments by relying on all five senses and various forms of cultural expressions that range from burning unsi to adorning the walls with Somali handicrafts. Unwilling to let go of valued Somali institutions, many had to make bounded choices like cooking while veiled in open kitchens, limiting children's play to accommodate formal impromptu visits, and restraining their social gatherings to the bedrooms to continue the tradition of gender separation. By proposing design solutions to the housing problems revealed through the study, this paper hopes to alert those who work with refugees and other immigrant groups that, with a little extra care, a house can be transformed into a home that fosters a sense of belonging and eases the stresses of adjusting to new life circumstances. [source] Upper susceptibility threshold limits with confidence intervals: a method to identify normal and abnormal population values for laboratory toxicological parameters, based on acetylcholinesterase activities in sea licePEST MANAGEMENT SCIENCE (FORMERLY: PESTICIDE SCIENCE), Issue 3 2006Anders Fallang Abstract The interpretation and importance of comparing field values of susceptibility to pesticides with a laboratory reference strain that might bear little resemblance to the actual situation in the field are problematic and a continuing subject of debate. In this paper a procedure for defining a ,normal sensitive' population from a field study of 383 individuals to provide a basis for analysing and interpreting in vitro results is described and examined. Instead of using only the 95th percentile, the upper and lower confidence limits for the 95th percentile were also compared to select the best estimation of the limit for the normal material. A field population constrained by the upper confidence limit for the 95th percentile provides appropriate descriptions of the normal material in this study. This approach should prove useful in studies of pesticide resistance in field populations. Copyright © 2006 Society of Chemical Industry [source] On Making Sense (and Nonsense) of HeideggerPHILOSOPHY AND PHENOMENOLOGICAL RESEARCH, Issue 3 2001TAYLOR CARMAN Herman Philipse's Heidegger's Philosophy of Being is an attempt to interpret, analyze, and ultimately discredit the whole of Heidegger's thought. But Philipse's reading of the texts is uncharitable, and the ideas he presents and criticizes often bear little resemblance to Heidegger's views. Philipse relies on a crude distinction between "theoretical" and "applicative" interpretations in arguing that Heidegger's conception of interpretation as a kind of projection (Entwurf) is, like the liar's paradox, formally self-defeating. But even granting the distinction, the charge of reflective incoherence is fallacious and question-begging. Finally, Philipse advances the astonishing "interpretive hypothesis" that the seemingly morbid existential themes in Being and Time were part of a deliberate "Pascalian strategy" to win converts to Heidegger's own idiosyncratic "postrnonotheist worship of Being." In short, notwithstanding its nearly comprehensive coverage of Heidegger's works, the book does not represent a sufficiently serious effort to understand the complexities and obscurities of Heidegger's thinking. [source] Subjective pain experience of people with chronic back painPHYSIOTHERAPY RESEARCH INTERNATIONAL, Issue 4 2000Professor Lorraine H De Souza Chair of Rehabilitation Abstract Background and Purpose Studies into the effect of pain experience on those who have it have largely focused on the views and interpretations of researchers gained by the use of assessment tools aimed at measuring pain. The purpose of this study was to explore and describe pain, as experienced by those with chronic back pain, and to document ,insider' accounts of how pain is perceived and understood by those who have it. Method Unstructured interviews using the framework approach. Subjects were sampled for age, sex, ethnicity and occupation, from new referrals with back pain to a rheumatology outpatient clinic. Eleven subjects (5 M; 6 F) agreed to be interviewed. Interviews were unstructured, but followed a topic guide. Subjects were interviewed in English (nine) or their preferred language (two). Tape-recordings of interviews were transcribed verbatim and read in depth twice to identify the topics or concepts. Data were extracted in the form of words and phrases by use of thematic content analysis. The themes were pain description and amount of pain. An independent researcher reviewed the data and confirmed or contended the analysis. Results All subjects, except one, provided descriptors of the quality of their pain. The use of simile was common to emphasize both what the pain was, and what it was not. Five subjects expressed a loss of words in trying to describe their pain. Only 13 of 29 different pain descriptors used were commensurate with those in the McGill Pain Questionnaire (Melzack, 1983). Subjects had great difficulty quantifying their pain intensity. Several explained how the pain fluctuated, thus, quantifying pain at one point in time was problematic. Only one subject offered a numerical description of pain intensity. Conclusions Subjects provided graphic and in-depth descriptions of their pain experience, but these bore little resemblance to commonly used assessment tools. The findings challenge the appropriateness of such formal instruments. Copyright © 2000 Whurr Publishers Ltd. [source] Optimal Commodity Taxes in AustraliaTHE AUSTRALIAN ECONOMIC REVIEW, Issue 1 2002Paul Blacklow The recent changes to commodity taxes in Australia have led to renewed interest in a classic question in public finance: should the tax rates be uniform or differentiated? This article attempts to answer this question by calculating optimal commodity taxes in Australia for a nine-item disaggregation. The estimates point to non-uniform commodity taxes, even from the viewpoint of an inequality-insensitive tax planner. The optimal commodity taxes bear little resemblance with the pre-GST or post-GST tax rates. No less significant is our observation that even the purely efficiency-driven optimal commodity taxes imply lower real expenditure inequality than the actual taxes. [source] Averting the baiji syndrome: conserving habitat for critically endangered dolphins in Eastern Taiwan StraitAQUATIC CONSERVATION: MARINE AND FRESHWATER ECOSYSTEMS, Issue 6 2010Peter S. Ross Abstract 1.Numbering no more than 100 individuals and facing many threats, the geographically isolated Eastern Taiwan Strait population of Indo-Pacific humpback dolphins (Sousa chinensis) is in peril. The estuarine and coastal waters of central-western Taiwan have historically provided prime habitat for these dolphins, but environmental conditions today bear little resemblance to what they were in the past. 2.The humpback dolphins must share their habitat with thousands of fishing vessels and numerous factories built upon thousands of hectares of reclaimed land. 3.They are exposed to chemicals and sewage released from adjacent terrestrial activities. Noise and disturbance associated with construction, vessel traffic and military activities are features of everyday life for these animals. 4.Measures to slow the pace of habitat deterioration and reduce the many risks to the dolphins are urgently needed. As one practical step in this direction, this paper describes the habitat needs of these small cetaceans so that decision makers will be better equipped to define ,priority habitat' and implement much needed protection measures under the terms of local legislation. 5.The preferred habitat of these dolphins in Taiwan consists of shallow (<30,m), near-shore marine waters with regular freshwater inputs. 6.For such a small, isolated and threatened population, ,priority habitat' should not be limited to areas of particularly intensive dolphin use or high dolphin density, but rather it should encompass the entire area where the animals have been observed (their current ,habitat'), as well as additional coastal areas with similar bio-physical features (,suitable habitat'). Such a precautionary approach is warranted because the loss of only a few individuals could have serious population-level consequences. 7.While conventional socio-economic analysis might suggest that implementing protection measures over an area stretching ,350,km north,south along Taiwan's west coast and ,3,km out to sea would be too ,costly', the loss of this charismatic species from Taiwan's waters would send a troubling message regarding our collective ability to reconcile human activities with environmental sustainability.
