Kinds of Hall Terms modified by Hall Selected AbstractsANALYSIS OF NASRID POLYCHROME CARPENTRY AT THE HALL OF THE MEXUAR PALACE, ALHAMBRA COMPLEX (GRANADA, SPAIN), COMBINING MICROSCOPIC, CHROMATOGRAPHIC AND SPECTROSCOPIC METHODS,ARCHAEOMETRY, Issue 4 2009C. CARDELL The pigments, binders and execution techniques used by the Nasrids (1238,1492) to polychrome carpentry in the Hall of the Mexuar Palace at the Alhambra (Granada, Spain) were studied using optical microscopy, scanning electron microscopy with EDX analysis, selective staining techniques and gas chromatography , mass spectrometry. This pioneering investigation presents the first results of a research project devoted to filling gaps in the knowledge of Nasrid art, traditionally approached by stylistic studies. Moreover, it is essential for the polychromy conservation of the studied artworks, and will help to clarify historical and painting uncertainties in the Alhambra monument. The palette consists of a limited range of colours: white (lead-base pigment), red (cinnabar and red lead), blue (lapis lazuli), black (carbon-based) and false gold (golden tin). Tempera grassa was the painting technique identified. Two types of grounds were used: (i) gypsum in calligraphy decoration for the false gold technique, and (ii) synthetic minium in geometric drawings in carpentry. Organic insulating layers of linseed oil were used between paint strata. Artists applied synthetic minium to protect the wood (Juglans regia and conifer) against attack by xylophages. To lighten the surface darkened by this ground layer, powdered tin was added to achieve a metallic lustre. [source] PROCESSION AND SYMBOLISM AT TARA: ANALYSIS OF TECH MIDCHÚARTA (THE ,BANQUETING HALL') IN THE CONTEXT OF THE SACRAL CAMPUSOXFORD JOURNAL OF ARCHAEOLOGY, Issue 4 2007CONOR NEWMAN Summary. New analysis explores Tech Midchúarta (the ,Banqueting Hall') from the point of view of a sacral, processional approach to the summit of the Hill of Tara, the pre-eminent cult and inauguration site of prehistoric and early medieval Ireland. It is suggested that aspects of its architectural form symbolize the liminal boundary between the human world and the Otherworld of Tara, and that in so far as Tech Midchúarta is also designed to control and manipulate how the ceremonial complex is disclosed to the observer, it assembles the existing monuments into one, integrated ceremonial campus. It is argued that Tech Midchúarta is one of the later monuments on the Hill of Tara and that it may date from the early medieval period. Using the evidence of documentary sources and extant monuments, a possible processional route from Tech Midchúarta to Ráith na Ríg is described.

Vlasov Abstract Experimental results on solid-state arsenic doping of the n-type bulk and ISOVPE epitaxial CdXHg1- XTe (X = 0.19 ÷ 0.3) alloys are presented. The arsenic doped thin epitaxial CdxHg1- xTe films (nAs , 5 · 1016 ÷ 1 · 1020 cm -3; d = 2 ÷ 5 ,m) obtained by RF sputtering in a mercury glow discharge were used as As diffusion sources. The arsenic diffusion and activation were carried out at temperatures T = 500 ÷ 600 °C under Hg vapour pressure. Immediately after the high temperature treatment all samples were annealed to annihilate point defects. The SIMS analysis was used for determination of the quantitative admixture distribution of As in the diffusion area. The arsenic electrical activity has been evaluated by means of differential Hall, resistivity and thermoemf measurements. The analysis of experimental data obtained as well as their comparison with previously obtained results has been performed. (© 2004 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source] Inelastic deformation response of SDOF systems subjected to earthquakesEARTHQUAKE ENGINEERING AND STRUCTURAL DYNAMICS, Issue 3 2002Rafael Riddell Abstract Performance-based seismic design requires reliable methods to predict earthquake demands on structures, and particularly inelastic deformations, to ensure that specific damage-based criteria are met. Several methods based on the response of equivalent linear single-degree-of-freedom (SDOF) systems have been proposed to estimate the response of multi-degree-of-freedom structures. These methods do not offer advantages over the traditional Veletsos,Newmark,Hall (VNH) procedure, indeed, they have been shown to be inaccurate. In this study, the VNH method is revised, considering the inelastic response of elastoplastic, bilinear, and stiffness-degrading systems with 5% damping subjected to two sets of earthquake ground motions. One is an ensemble of 51 earthquake records in the Circumpacific Belt, and the other is a group of 44 records in California. A statistical analysis of the response data provides factors for constructing VNH inelastic spectra. Such factors show that the ,equal-displacement' and ,equal-energy' rules to relate elastic and inelastic responses are unconservative for high ductilities in the acceleration- and velocity-sensitive regions of the spectrum. It is also shown that, on average, the effect of the type of force,deformation relationship of non-linear systems is not significant, and responses can be conservatively predicted using the simple elastoplastic model.

Lee Summary Von Thünen's model of the relationship between concentrated urban demand and rural land use proposes that towns will draw agricultural produce from a series of zones of specialized production around the urban centre. Using the accounts of King's Hall and King's College, this article identifies the areas that supplied Cambridge with food and fuel during the fifteenth and sixteenth centuries, and the persistence of such trade. Local geographical conditions meant that, contrary to von Thünen's model, firewood and charcoal were brought from more distant regions than those supplying wheat and malt barley, and Cambridge's hinterland also had to compete with demand from London. [source] Prospects for the Euro: Why has it been so weak?ECONOMIC OUTLOOK, Issue 1 2001Stephen Hall In this article, Stephen Hall and Brian Henry consider the reasons for the Euro's weakness since its introduction and ask what are the likely prospects for a recovery to near-fundamental levels over the medium term. They conclude that the major factor leading to the currency's depreciation since 1999 has been a rise in the risk premium surrounding the Euro. A successful launch of Euro notes and coins may help to eliminate this premium. [source] The Independence of the Bank Of England: an UpdateECONOMIC OUTLOOK, Issue 2 2000Stephen Hall In this article, Stephen Hall and Brian Henry reconsider the arguments for further coordination of fiscal and monetary policy in the UK. The recent inflation-unemployment performance in the UK has been good, but it appears mainly the result of beneficial developments in the world economy. Further improvement in the policy-making framework in the UK is called for. Many of the present drawbacks could be dealt with by treating fiscal policy on a par with monetary policy. There are arguments that further cooperation is not needed but these are unpersuasive. They recommend the setting up of an independent committee charged with reviewing fiscal decisions, and coordinating these with monetary decisions by the MPC. [source] GOVERNMENT INTERVENTION IN CHILD REARING: GOVERNING INFANCYEDUCATIONAL THEORY, Issue 3 2010Robert A. Davis In this essay, Robert Davis argues that much of the moral anxiety currently surrounding children in Europe and North America emerges at ages and stages curiously familiar from traditional Western constructions of childhood. The symbolism of infancy has proven enduringly effective over the last two centuries in associating the earliest years of children's lives with a peculiar prestige and aura. Infancy is then vouchsafed within this symbolism as a state in which all of society's hopes and ideals for the young might somehow be enthusiastically invested, regardless of the complications that can be anticipated in the later, more ambivalent years of childhood and adolescence. According to Davis, the understanding of the concept of infancy associated with the rise of popular education can trace its pedigree to a genuine shift in sensibility that occurred in the middle of the eighteenth century. After exploring the essentially Romantic positions of Johann Heinrich Pestalozzi and Friedrich Fröbel and their relevance to the pattern of reform of early childhood education in the United Kingdom and the United States, Davis also assesses the influence of figures such as Stanley Hall and John Dewey in determining the rationale for modern early childhood education. A central contention of Davis's essay is that the assumptions evident in the theory and practice of Pestalozzi and his followers crystallize a series of tensions in the understanding of infancy and infant education that have haunted early childhood education from the origins of popular schooling in the late eighteenth century down to the policy dilemmas of the present day. [source] Urban Ethnography of the 1920s Working GirlGENDER, WORK & ORGANISATION, Issue 3 2007Jaber F. Gubrium The 1920s was the era of the city. The urban population of the USA for the first time exceeded the population of rural areas and the nascent institutions of city life were flourishing. This article discusses the urban ethnography of the era with a focus on the way women and work was conceptualized, especially how ,the city' figured in explanation. Three ethnographies are examined ,Frances Donovan'sThe Woman Who Waits (1920) and The Saleslady (1929) and Paul Cressey'sThe Taxi-Dance Hall (1932). Donovan and Cressey presented their empirical material to show that the so-called working girl faced a multifaceted world of opportunity in employment, not of disadvantage, as commonly emphasized in today's ethnographic studies of women and work. The conclusion reflects on the past, present and future in terms of the city's explanatory prominence in various eras. [source] Reconstruction of the Ross Ice Drainage System, Antarctica, at the Last Glacial MaximumGEOGRAFISKA ANNALER SERIES A: PHYSICAL GEOGRAPHY, Issue 2-3 2000George H. Denton We present here a revised reconstruction of the Ross ice drainage system of Antarctica at the last glacial maximum (LGM) based on a recent convergence of terrestrial and marine data. The Ross drainage system includes all ice flowlines that enter the marine Ross Embayment. Today, it encompasses one-fourth of the ice-sheet surface, extending far inland into both East and West Antarctica. Grounding lines now situated in the inner Ross Embayment advanced seaward at the LGM (radiocarbon chronology in Denton and Marchant 2000 and in Hall and Denton 2000a, b), resulting in a thick grounded ice sheet across the Ross continental shelf. In response to this grounding in the Ross (and Weddell) Embayment, ice-surface elevations of the marine-based West Antarctic Ice Sheet were somewhat higher at the LGM than at present (Steig and White 1997; Borns et al. 1998; Ackert et al. 1999). At the same time, surface elevations of the East Antarctic Ice Sheet inland of the Transantarctic Mountains were slightly lower than now, except near outlet glaciers that were dammed by grounded ice in the Ross Embayment. The probable reason for this contrasting behavior is that lowered global sea level at the LGM, from growth of Northern Hemisphere ice sheets, caused widespread grounding of the marine portion of the Antarctic Ice Sheet, whereas decreased LGM accumulation led to slight surface lowering of the interior terrestrial ice sheet in East Antarctica. Rising sea level after the LGM tripped grounding-line recession in the Ross Embayment, which has probably continued to the present day (Conway et al. 1999). Hence, gravitational collapse of the grounded ice sheet from the Ross Embayment, accompanied by lowering of the interior West Antarctic ice surface and of outlet glaciers in the Transantarctic Mountains, occurred largely during the Holocene. At the same time, increased Holocene accumulation caused a slight rise of the inland East Antarctic ice surface. [source] Interpretation of Spring Recession CurvesGROUND WATER, Issue 5 2002H. Amit Recession curves contain information on storage properties and different types of media such as porous, fractured, cracked lithologies and karst. Recession curve analysis provides a function that quantitatively describes the temporal discharge decay and expresses the drained volume between specific time limits (Hall 1968). This analysis also allows estimating the hydrological significance of the discharge function parameters and the hydrological properties of the aquifer. In this study, we analyze data from perennial springs in the Judean Mountains and from others in the Galilee Mountains, northern Israel. All the springs drain perched carbonate aquifers. Eight of the studied springs discharge from a karst dolomite sequence, whereas one flows out from a fractured, slumped block of chalk. We show that all the recession curves can be well fitted by a function that consists of two exponential terms with exponential coefficients ,1 and ,2. These coefficients are approximately constant for each spring, reflecting the hydraulic conductivity of different media through which the ground water flows to the spring. The highest coefficient represents the fast flow, probably through cracks, or quickflow, whereas the lower one reflects the slow flow through the porous medium, or baseflow. The comparison of recession curves from different springs and different years leads to the conclusion that the main factors that affect the recession curve exponential coefficients are the aquifer lithology and the geometry of the water conduits therein. In normal years of rainy winter and dry summer, ,1 is constant in time. However, when the dry period is longer than usual because of a dry winter, ,1 slightly decreases with time. [source] TNM-based stage groupings in head and neck cancer: Application in cancer of the hypopharynxHEAD & NECK: JOURNAL FOR THE SCIENCES & SPECIALTIES OF THE HEAD AND NECK, Issue 1 2009FRCSC, Stephen F. Hall MSc Abstract Background. The purpose of this study was to test the Union Internationale Contre le Cancer (UICC)/TNM category,based head and neck cancer stage grouping systems proposed in the literature for their ability to create clinically relevant prognostic groups of like-patients with cancer of the hypopharynx. Methods. Population-based retrospective survival study of 595 patients with squamous cell carcinoma of the hypopharynx across Ontario, Canada, from January 1990 to January 2000. The grouping systems of UICC/TNM, T and N Integer Score (TANIS), Hart, Berg, Snyderman, Kiricuta, and Hall were tested and compared for prognostic ability using hazard consistency, hazard discrimination, percent variance explained, outcome prediction, and balance. Results. All 8 systems predicted disease-specific survival. The system proposed by Snyderman performed the best, and UICC/TNM sixth edition did not perform as well as most. Conclusion. The UICC/TNM stage group classification, although successful in creating statistically distinct groups, did not perform as well as other stage grouping systems, continuing a theme that has been reported previously. © 2008 Wiley Periodicals, Inc. Head Neck, 2009 [source] Some Afterthoughts on Culture and Explanation in Historical InquiryHISTORY AND THEORY, Issue 3 2000Chris Lorenz I argue here that the articles in this forum contain basic agreements. All three reject naturalism, reductionism, and monism while retaining causality as an explanatory category, and all three emphasize the role of time and argue for a view in which culture is regarded as both structured and contingent. The differences among the explanatory proposals of Hall, Biernacki, and Kane are as important as the similarities: while Hall favors a Weberian approach, Biernacki argues for a primarily pragmatic explanation of culture, and Kane for a primarily semiotic explanation. I argue that all three positions face immanent problems in elucidating the exact nature of cultural explanation. While Hall leaves the problem of "extrinsic" ideal-typical explanation unsolved, Biernacki simply presupposes the superiority of pragmatic over other types of cultural explanation, and Kane does the same for semiotic explanation. Hints at cultural explanation in the form of narrative remain underargued and are built on old ideas of an opposition between "analysis" and "narrative." This is also the case with the latest plea for "analytic narratves." I conclude that a renewed reflection on this opposition is called for in order to come to grips with cultural explanation and to get beyond the old stereotypes regarding the relationship between historical and social-scientific approaches to the past. [source] TOPCAT-NP: a minimum information requirement model for simulation of flow and nutrient transport from agricultural systemsHYDROLOGICAL PROCESSES, Issue 14 2008P. F. Quinn Abstract Future catchment planning requires a good understanding of the impacts of land use and management, especially with regard to nutrient pollution. A range of readily usable tools, including models, can play a critical role in underpinning robust decision-making. Modelling tools must articulate our process understanding, make links to a range of catchment characteristics and scales and have the capability to reflect future land-use management changes. Hence, the model application can play an important part in giving confidence to policy makers that positive outcomes will arise from any proposed land-use changes. Here, a minimum information requirement (MIR) modelling approach is presented that creates simple, parsimonious models based on more complex physically based models, which makes the model more appropriate to catchment-scale applications. This paper shows three separate MIR models that represent flow, nitrate losses and phosphorus losses. These models are integrated into a single catchment model (TOPCAT-NP), which has the advantage that certain model components (such as soil type and flow paths) are shared by all three MIR models. The integrated model can simulate a number of land-use activities that relate to typical land-use management practices. The modelling process also gives insight into the seasonal and event nature of nutrient losses exhibited at a range of catchment scales. Three case studies are presented to reflect the range of applicability of the model. The three studies show how different runoff and nutrient loss regimes in different soil/geological and global locations can be simulated using the same model. The first case study models intense agricultural land uses in Denmark (Gjern, 114 km2), the second is an intense agricultural area dominated by high superphosphate applications in Australia (Ellen Brook, 66 km2) and the third is a small research-scale catchment in the UK (Bollington Hall, 2 km2).

[source] Sampling Practices of Internal Auditors at Corporations on the Standard & Poor's Toronto Stock Exchange Composite Index,ACCOUNTING PERSPECTIVES, Issue 3 2009Michael Maingot ABSTRACT The purpose of this study is to find out how often statistical and nonstatistical audit sampling practices are used by internal auditors in companies listed on the Standard and Poor's (S&P) Toronto Stock Exchange (TSX) Composite Index and how such practices are related to the training and background of the respondents. We adapted the questionnaire used by Hall, Hunton, and Pierce (2002) in their survey of U.S. auditors in public accounting, industry, and government. Although 20 percent of companies responding do not have an internal audit department, the other 80 percent use statistical methods to plan sample sizes 15 percent (+5 percent) of the time, random sample selection methods 23 percent (+5 percent) of the time, but statistical evaluation methods only 10% (+4%) of the time. Despite the low percentage use, almost half of the respondents reported substantial training in statistical sampling and evaluation methods. Moreover, we found statistically significantly higher proportions of respondents with substantial training in audit sampling methods among companies cross-listed on U.S. exchanges compared with companies listed only on the TSX. Finally, respondents with a chartered accountant designation tend to have a negative impact on the use of statistical methods in audit sampling, and companies cross-listed on U.S. exchanges tend to have larger internal audit departments than companies listed only on the TSX. [source] About Darcy's law in non-Galilean frameINTERNATIONAL JOURNAL FOR NUMERICAL AND ANALYTICAL METHODS IN GEOMECHANICS, Issue 3 2004C. Geindreau Abstract This paper is aimed towards investigating the filtration law of an incompressible viscous Newtonian fluid through a rigid non-inertial porous medium (e.g. a porous medium placed in a centrifuge basket). The filtration law is obtained by upscaling the flow equations at the pore scale. The upscaling technique is the homogenization method of multiple scale expansions which rigorously gives the macroscopic behaviour and the effective properties without any prerequisite on the form of the macroscopic equations. The derived filtration law is similar to Darcy's law, but the tensor of permeability presents the following remarkable properties: it depends upon the angular velocity of the porous matrix, it verifies Hall,Onsager's relationship and it is a non-symmetric tensor. We thus deduce that, under rotation, an isotropic porous medium leads to a non-isotropic effective permeability. In this paper, we present the results of numerical simulations of the flow through rotating porous media. This allows us to highlight the deviations of the flow due to Coriolis effects at both the microscopic scale (i.e. the pore scale), and the macroscopic scale (i.e. the sample scale). The above results confirm that for an isotropic medium, phenomenological laws already proposed in the literature fails at reproducing three-dimensional Coriolis effects in all types of pores geometry. We show that Coriolis effects may lead to significant variations of the permeability measured during centrifuge tests when the inverse Ekman number Ek,1 is ,,(1). These variations are estimated to be less than 5% if Ek,1<0.2, which is the case of classical geotechnical centrifuge tests. We finally conclude by showing that available experimental data from tests carried out in centrifuges are not sufficient to determining the effective tensor of permeability of rotating porous media.

S. Hall. In 1910, A Photographic Album of Experimental Psychology was published, which included many photographs of psychophysical experiments. In 1933, Sadaji Takagi conducted the first experiment on animal psychophysics to investigate shape constancy in small birds. In 1949, the first experiment on infant psychophysics was conducted by Jyuji Misumi to study the early development of size constancy. And, in 1955, Tadasu Oyama proposed a new psychophysical technique, naming the method of transposition to measure perceived size ratios without using numerical expressions. This method has been successfully applied to the measurement of illusions, figural after-effects, and size constancy. In 1960, Tarow Indow and his collaborators published their first systematic application of multidimensional scaling to color perception. They also applied it to study the perceptual structure of visual space. Recent developments in those topics in Japan are also reviewed.

[source] HIV disclosure among HIV positive individuals: a concept analysisJOURNAL OF ADVANCED NURSING, Issue 9 2010Rosemary W. Eustace eustace r.w. & ilagan p.r. (2010) HIV disclosure among HIV positive individuals: a concept analysis. Journal of Advanced Nursing,66(9), 2094,2103. Abstract Aim., This paper is a report of an analysis of the concept of HIV disclosure. Background., There is a growing interest among healthcare providers and researchers in HIV disclosure as an effective HIV prevention and early disease management initiative. However, the concept still remains unclear. Conceptual clarity is important for providing an expanded theoretical definition and understanding of attributes of HIV disclosure. This information is useful in constructing better HIV disclosure measures in HIV/AIDS nursing practice and research. Data sources., A computer search of the following databases was conducted to capture the meaning and processes of HIV disclosure among HIV-positive individuals: PubMed, CINAHL and PSYCINFO. Only English language journals were used. Publication dates of the literature review ranged from 1999 to 2009. The following key words were used: HIV disclosure, self-disclosure, disclosure and serostatus disclosure. Methods., The Walker and Avant (2005) concept analysis model (Strategies for Theory Construction in Nursing, Pearson Prentice Hall, River, NJ, 2005) was used to guide the analysis process, which was completed in 2009. Results., The concept analysis revealed that HIV disclosure is a complex process characterized by the following attributes: experiencing an event, communicating something, timing, and contextual environment, protecting someone, relationship status and improving something or being therapeutic. In addition, the process of HIV disclosure varies across time. Conclusion., The proposed HIV disclosure attributes provide nursing scholars and researchers with new directions on how to reframe research questions, develop measurement tools to reflect better the diversity and fluidity of the process of HIV disclosure among HIV-positive individuals. Policy implications include the need to develop approaches that protect individual and public rights. [source] Narcissism and Cardiovascular Reactivity to Rejection Imagery,JOURNAL OF APPLIED SOCIAL PSYCHOLOGY, Issue 5 2009Kristin L. Sommer This study examined the interactive effects of imagined rejection and narcissism on cardiovascular reactivity (CVR). Participants completed measures of overt narcissism (Narcissistic Personality Inventory, NPI; Raskin & Hall, 1979), overt,covert narcissism (Margolis & Thomas, 1980), and trait self-esteem. They then imagined 2 scenarios culminating in either interpersonal acceptance or rejection. Systolic (SBP) and diastolic blood pressure (DBP) and heart rate (HR) were assessed before, during, and after the imagery. Overt,covert narcissism was positively associated with task increases in SBP and DBP and recovery elevation of HR following rejection, but not acceptance. Similar effects on SBP were found for the Entitlement/Exploitativeness dimension of the NPI. Lower self-esteem predicted greater task increases in SBP, DBP, and HR across conditions. Implications for health are discussed. [source] Examining psychopathic tendencies in adolescence from the perspective of personality theoryAGGRESSIVE BEHAVIOR, Issue 5 2009Naomi Sadeh Abstract This study sought to clarify the personality correlates of psychopathic tendencies in adolescents using the Antisocial Process Screening Device [APSD; Frick and Hare, 2001] and a youth adapted version of the Multidimensional Personality Questionnaire [Patrick et al., 2009, unpublished]. A combination of self- and parent-reports on the APSD (n=229) revealed that the three-facet model of psychopathic tendencies in youth was characterized by a similar constellation of personality traits as the psychopathic construct in adulthood [e.g., Hall, Benning and Patrick, 2004]. Specifically, low anxiety and trait aggression characterized the APSD Callous/Unemotional dimension, social dominance and trait aggression characterized the APSD Narcissism dimension, and disinhibition and low harm avoidance characterized the APSD Impulsivity dimension. The results add credence to the hypothesis that personality relationships to psychopathic tendencies emerge from an early age [Lynam, 2002] and dimensions of psychopathy in youth are associated with distinct personality profiles.

Blaer Constructing highly detailed three-dimensional (3-D) models of large complex sites using range scanners can be a time-consuming manual process. One of the main drawbacks is determining where to place the scanner to obtain complete coverage of a site. We have developed a system for automatic view planning called VuePlan. When combined with our mobile robot, AVENUE, we have a system that is capable of modeling large-scale environments with minimal human intervention throughout both the planning and acquisition phases. The system proceeds in two distinct stages. In the initial phase, the system is given a two-dimensional site footprint with which it plans a minimal set of sufficient and properly constrained covering views. We then use a 3-D laser scanner to take scans at each of these views. When this planning system is combined with our mobile robot it automatically computes and executes a tour of these viewing locations and acquires them with the robot's onboard laser scanner. These initial scans serve as an approximate 3-D model of the site. The planning software then enters a second phase in which it updates this model by using a voxel-based occupancy procedure to plan the next best view (NBV). This NBV is acquired, and further NBVs are sequentially computed and acquired until an accurate and complete 3-D model is obtained. A simulator tool that we developed has allowed us to test our entire view planning algorithm on simulated sites. We have also successfully used our two-phase system to construct precise 3-D models of real-world sites located in New York City: Uris Hall on the campus of Columbia University and Fort Jay on Governors Island. © 2009 Wiley Periodicals, Inc. [source] Ordering the alternatives of a strategic plan for Valencia (Spain)JOURNAL OF MULTI CRITERIA DECISION ANALYSIS, Issue 3 2001Pablo Aragonés Abstract In this article we present an evaluation of the initiatives involved in a Strategic Plan for Valencia City (Spain) by applying a method to assist Multi-Criteria Decision-Making. The complexity of the case lies in the size of the problem, 47 alternatives and 10 criteria, as well as the need to reach a consensus on the final result. The method followed, which has been named PRES Multi-expert, can be generalized and applied to other complex cases. Thirteen experts have participated in the process, representing different political and social groups of the City, a group of analysts, formed by three lecturers from the Polytechnic University of Valencia, and a consultant, representing the City Hall of Valencia. The PRES algorithm was used to order the alternatives developed in 1992 by Gómez-Senent at this University. In this article we highlight the advantages of applying the Multi-Criteria Decision-Making Aid techniques and the importance of following a procedure to select the criteria, pondering on them and evaluating the alternatives. This procedure ensures that the parties interested in or affected by the decision take part in deciding what measures to adopt. The Multi-expert PRES method facilitates this participation and can be adapted to different types of problems. Copyright © 2001 John Wiley & Sons, Ltd.

Department of Biology, Coker Hall, University of North Carolina, Chapel Hill, NC 27599-3280 USA Theories about the geographical distribution of marine algae fall roughly into two categories: (1) a concept of biogeographical regions in which algal distribution is determined primarily by growth, reproductive and lethal temperature boundaries (Setchell, van den Hoek, Breeman, Lüning) and (2) an historical perspective in which distribution is determined primarily by patterns of dispersal and the establishment of barriers to dispersal (vicariance biogeography) (Svedelius, Garbary, Lindstrom, Hommersand). Setchell proposed the 5° isotherm rule in 1920, and in 1924 Svedelius advocated a worldwide distribution for tropical and subtropical groups followed by discontinuous distribution upon closure of the connection between the Indian Ocean and Mediterranean Sea and, later, between North and South America (Wegener's theory). Transarctic dispersal routes have received special attention in recent years (Lindstrom, Lüning, van Oppen, Olsen, Stam), as have special relationships between Australasia, South Africa and South America (Hommersand). Less well understood are the climatic changes that have taken place in the Cenozoic which are strategic to an understanding vicariant biogeography. The advent of molecular methods combined with the tools of phylogenetic systematics now make it possible to identify ancestral taxa, test the consistency of tree topologies, and calculate mean branch lengths between sister lineages diverging from an interior node of a tree. With such methods it may be possible to infer ancestral areas, identify dispersal pathways, determine the chronology of isolating events, assess the impact of multiple invasions, and generally relate dispersal and vicariance models to phylogenetic hypotheses for red, brown and green algal taxa.

Department of Environmental and Plant Biology, Ohio University, Athens, OH 45701 USA The freshwater red alga Batrachospermum helminthosum was collected from eleven streams throughout the species range in eastern North America as follows: three stream reaches from Ohio, and one each from Michigan, Indiana, Tennessee, Louisiana, North Carolina, Connecticut, Rhode Island and Massachusetts. The molecular marker technique of inter-simple sequence repeats (ISSR) and sequence data from the plastid encoded rubisco large subunit gene (rbcL), the mitochondrial COX2-COX3 gene spacer region, and the nuclear region of ITS1-5.8S rDNA-ITS2 were employed to examine biogeographic trends in this alga. Analysis of the rbcL sequence revealed 5 genotypes with one genotype representing individuals from seven stream reaches. Data from the ISSR molecular markers gave a distinct banding pattern for each of 165 individuals examined. ISSR results showed all individuals within a reach clustered together but did not provide well-defined groupings based on stream reach. The sequence data for the COX2-COX3 gene spacer was invariant among individuals from a stream reach. The individuals from Connecticut, Rhode Island and 2 Ohio stream reaches were identical and similarly the individuals from the North Carolina and another Ohio location did not vary in sequence so that seven genotypes were recorded among the individuals from the eleven stream reaches. Analysis of the ITS1-5.8S rDNA-ITS2 region showed sequence variation not only among individuals from different streams but also among individuals from the same reach. The utility and congruency of these data sets to answer biogeographic questions will be discussed. [source] Glacial modification of granite tors in the Cairngorms, Scotland,JOURNAL OF QUATERNARY SCIENCE, Issue 8 2006A. M. Hall Abstract A range of evidence indicates that many granite tors in the Cairngorms have been modified by the flow of glacier ice during the Pleistocene. Comparisons with SW England and the use of a space,time transformation across 38 tor groups in the Cairngorms allow a model to be developed for progressive glacial modification. Tors with deeply etched surfaces and no, or limited, block removal imply an absence of significant glacial modification. The removal of superstructure and blocks, locally forming boulder trains, and the progressive reduction of tors to stumps and basal slabs represent the more advanced stages of modification. Recognition of some slabs as tor stumps from which glacial erosion has removed all superstructure allows the original distribution of tors to be reconstructed for large areas of the Cairngorms. Unmodified tors require covers of non-erosive, cold-based ice during all of the cold stages of the Middle and Late Pleistocene. Deformation beneath cold-based glacier ice is capable of the removal of blocks but advanced glacial modification requires former wet-based glacier ice. The depth of glacial erosion at former tor sites remains limited largely to the partial or total elimination of the upstanding tor form. Cosmogenic nuclide exposure ages (Phillips et al., 2006) together with data from weathering pit depths (Hall and Phillips, 2006), from the surfaces of tors and large erratic blocks require that the glacial entrainment of blocks from tors occurred in Marine Isotope Stages (MIS) 4,2, 6 and, probably, at least one earlier phase. The occurrence of glacially modified tors on or close to, the main summits of the Cairngorms requires full ice cover over the mountains during these Stages. Evidence from the Cairngorms indicates that tor morphology can be regarded as an important indicator of former ice cover in many formerly glaciated areas, particularly where other evidence of ice cover is sparse. Recognition of the glacial modification of tors is important for debates about the former existence of nunataks and refugia. Copyright © 2006 John Wiley & Sons, Ltd. [source] G. Stanley Hall: Neither Psychology Alone Nor Basic Research is SufficientJOURNAL OF RESEARCH ON ADOLESCENCE, Issue 4 2005James Youniss In his monumental work, Adolescence, G. Stanley Hall showed the value of interdisciplinary scholarship and respect for research, which had a policy orientation. Over the course of the 20th century these two characteristics faded in adolescent studies as psychology took dominance and basic research was given priority over policy considerations. An argument is made that there is value in revisiting Hall's approach as studies of adolescence can be enriched through interdisciplinary efforts and research which brings policy to the forefront.
