1. Rumler, Fabio; Computable general equilibrium modeling: (in English) This paper presents the concept of numerical CGE modeling with the help of a 2-country general equilibrium model. In the framework of this simple dynamic monetary model the effects of a (unilateral) monetary and fiscal expansion are simulated. The exchange rate of the home vis-a-vis the foreign currency depreciates in response to both types of shocks. The monetary expansion leads to an increase in home relative to foreign private consumption and to a sharp increase in relative home output in the short run, while in the long run output increases in the foreign country and decreases in the home country. The unilateral fiscal expansion, on the other hand, results in a fall of private consumption in the home relative to the foreign country, and in an increase in relative home output in the short as well as in the long run. The world real interest rate falls quite substantially in response to both shocks. (author's abstract), Working Paper, Wirtschaftsuniversitat Wien [Text] [View with Perseus links] (2.18)

2. Gaunersdorfer, Andrea; Hommes, Cars H.; A nonlinear structural model for volatility clustering: (in English) A simple nonlinear structural model of endogenous belief heterogeneity is proposed. News about fundamentals is an IID random process, but nevertheless volatility clustering occurs as an endogenous phenomenon caused by the interaction between different types of traders, fundamentalists and technical analysts. The belief types are driven by an adaptive, evolutionary dynamics according to the success of the prediction strategies in the recent past conditioned upon price deviations from the rational expectations fundamental price. Asset prices switch irregularly between two different regimes -- close to the fundamental price fluctuations with low volatility, and periods of persistent deviations from fundamentals triggered by technical trading - thus, creating time varying volatility similar to that observed in real financial data.

3. Gaunersdorfer, Andrea; Hommes, Cars H.; Wagener, Florian O. O.; Bifurcation routes to volatility clustering: (in English) A simple asset pricing model with two types of adaptively learning traders, fundamentalists and technical analysts, is studied. Fractions of these trader types, which are both boundedly rational, change over time according to evolutionary learning, with technical analysts conditioning their forecasting rule upon deviations from a benchmark fundamental. Volatility clustering arises endogenously in this model. Two mechanisms are proposed as an explanation. The first is coexistence of a stable steady state and a stable limit cycle, which arise as a consequence of a so-called Chenciner bifurcation of the system. The second is intermittency and associated bifurcation routes to strange attractors. Both phenomena are persistent and occur generically in nonlinear multi-agent evolutionary systems.

1. Far-West sketches, by Jessie Benton Fremont: (in English) Jessie Benton Fremont (1824-1902), the daughter of a Missouri Senator and wife of explorer John Charles Fremont, first came to California in 1849, when she and her young daughter spent six months at her husband's newly-acquired ranch at Mariposas, 140 miles east of San Francisco. The Fremonts also spent the years 1851-1852 and 1857-1861 at the Mariposas ranch before moving to St. Louis during the Civil War. They returned to California in 1887 and made Los Angeles their home for the rest of their lives. Far-West Sketches (1890) was inspired by Mrs. Fremont's 1887 railroad trip to California, a journey that prompts her to reminiscence about her earlier stay in the state in the 1850s with anecdotes of the minefields, ranching, and a home in the bustling town of San Francisco. The reminiscences center on homemaking and childrearing. [Text] (8.50)

2. Gerstacker's travels. Rio de Janeiro--Buenos Ayres--Ride through the pampas--Winter journey across the Cordilleras--Chili--Valparaiso--California and the gold fields. Tr. from the German of Frederick Gerstacker: (in English) Friedrich Gerstacker (1816-1872), a native of Hamburg, left Germany in 1837 for a six-year stay in New York. On his return to Germany, he published two travel memoirs, and the Frankfurt government subsidized his return to America in 1849 to collect information for prospective emigrants to California. On his return home, he published several books dealing with his travels. Gerstacker's travels (1854) is the English edition of the author's Reisen, published in Germany not long after his return to California. Nearly one half of the book is devoted to the sea journey with stops in Rio de Janeiro, Buenos Aires and the Argentine pampas, crossing the Cordilleras to Valparaiso, Chile, where he obtained passage to California. He describes San Francisco and Sacramento in the fall of 1849 as well as his experiences as a prospector on the Feather River. Leaving the gold fields, Gerstacker then spends several weeks at the Mission Dolores before trying his luck in 1850 at the goldfields beyond Stockton at Murphy's Diggings, San Antonio, and Mokelumne. He concludes with his voyage home from California via Honolulu, Australia, and the Dutch East Indies. [Text] (8.50)

3. Ten years in Paradise. Leaves from a society reporter's note-book. By Mary Bowden Carroll: (in English) Mary Bowden Carroll left Otsego County, New York, for San Jose, Santa Clara County, in 1892. Ten years in Paradise (1903) is less a personal memoir than a piece of promotional literature for her adopted home: summary of Santa Clara's social history, descriptions of local towns, tributes to the valley's commerce and industry, and attractions for the home seeker. A substantial portion of the book consists of brief descriptions of local clubs and societies with lists of their membership rolls. [Text] (8.26)

1. Brazil, Kevin, Bedard, Michel, Willison, Kathleen; Factors associated with home death for individuals who receive home support services: a retrospective cohort study: (in English) AbstractObjectivesTo determine the factors associated with a home death among older adults who received palliative care nursing home services in the home.MethodsThe participants in this retrospective cohort study were 151 family caregivers of patients who had died approximately 9 months prior to the study telephone interview. The interview focused on the last year of life and covered two main areas, patient characteristics and informal caregiver characteristics.ResultsOdds ratios [OR] and 95% confidence intervals [95% CI] were used to determine which of the 15 potential informal caregiver and seven patient predictor variables were associated with dying at home. Multivariate analysis revealed that the odds of dying at home were greater when the patient lived with a caregiver [OR = 7.85; 95% CI = (2.35, 26.27)], the patient stated a preference to die at home [OR= 6.51; 95% CI = (2.66,15.95)], and the family physician made home visits [OR = 4.79; 95% CI = (1.97,11.64)]. However the odds were lower for patients who had caregivers with fair to poor health status [OR = 0.22; 95% CI = (0.07, 0.65)] and for patients who used hospital palliative care beds [OR = 0.31; 95% CI = (0.12, 0.80)].DiscussionThe findings suggest that individuals who indicated a preference to die at home and resided with a healthy informal caregiver had better odds of dying at home. Home visits by a family physician were also associated with dying at home. [Text] [View with Perseus links] (2.94)

2. ... ; Clinical outcomes resulting from telemedicine interventions: a systematic review: (in English) AbstractBackgroundThe use of telemedicine is growing, but its efficacy for achieving comparable or improved clinical outcomes has not been established in many medical specialties. The objective of this systematic review was to evaluate the efficacy of telemedicine interventions for health outcomes in two classes of application: home-based and office/hospital-based.MethodsData sources for the study included deports of studies from the MEDLINE, EMBASE, CINAHL, and HealthSTAR databases; searching of bibliographies of review and other articles; and consultation of printed resources as well as investigators in the field. We included studies that were relevant to at least one of the two classes of telemedicine and addressed the assessment of efficacy for clinical outcomes with data of reported results. We excluded studies where the service did not historically require face-to-face encounters (e.g., radiology or pathology diagnosis). All included articles were abstracted and graded for quality and direction of the evidence.ResultsA total of 25 articles met inclusion criteria and were assessed. The strongest evidence for the efficacy of telemedicine in clinical outcomes comes from home-based telemedicine in the areas of chronic disease management, hypertension, and AIDS. The value of home glucose monitoring in diabetes mellitus is conflicting. There is also reasonable evidence that telemedicine is comparable to face-to-face care in emergency medicine and is beneficial in surgical and neonatal intensive care units as well as patient transfer in neurosurgery.ConclusionsDespite the widespread use of telemedicine in virtually all major areas of health care, evidence concerning the benefits of its use exists in only a small number of them. Further randomized controlled trials must be done to determine where its use is most effective. [Text] [View with Perseus links] (0.64)

3. ... ; Compulsive checking behavior of quinpirole-sensitized rats as an animal model of Obsessive-Compulsive Disorder(OCD): form and control: (in English) AbstractBackgroundA previous report showed that the open field behavior of rats sensitized to the dopamine agonist quinpirole satisfies 5 performance criteria for compulsive checking behavior. In an effort to extend the parallel between the drug-induced phenomenon and human obsessive-compulsive disorder (OCD), the present study investigated whether the checking behavior of quinpirole rats is subject to interruption, which is an attribute characteristic of OCD compulsions. For this purpose, the rat's home-cage was placed into the open field at the beginning or the middle of a 2-hr test.ResultsIntroduction of the home-cage reduced checking behavior, as rats stayed inside the cage. After 40 min, checking resurfaced, as quinpirole rats exited the home-cage often. An unfamiliar cage had no such effects on quinpirole rats or saline controls.ConclusionsChecking behavior induced by quinpirole is not irrepressible but can be suspended. Results strengthen the quinpirole preparation as an animal model of OCD compulsive checking. [Text] [View with Perseus links] (0.59)

On montre ainsi que la sequence RARE permet d'acquerir des images de bonne qualite en moins de 400 ms avec peu de gaz ; la sequence EPI a l'avantage de la rapidite mais entraine davantage d'artefacts, en particulier en raison du terme de Maxwell ; ces deux sequences sont intrinsequement limitees en resolution a 5 mm in vivo ; la sequence FLASH, moins efficace en termes de rapport signal sur bruit, permet cependant d'atteindre de meilleures resolutions. Les avantages de l'utilisation d'un bas champ magnetique en regime hyperpolarise sont discutes : en particulier, le rapport signal sur bruit est, dans une tres large gamme, independant du champ principal. Des mesures RMN puis IRM de diffusion utilisant la technique CPMG sont presentees et permettent de mettre en evidence la restriction due a la structure alveolaire des poumons. ---------- This thesis reports the implementation of Magnetic Resonance Imaging (MRI) of hyperpolarised helium-3 at 0.1 T and at 1.5 T in vivo in healthy volunteers. Using hyperpolarised gas in MRI results in two major consequences: the longitudinal magnetisation cannot be restored and strong diffusion effects occur. Considering this, different strategies of acquisition were compared at low field (0.1 T): single-shot sequences (RARE and EPI) and multishot (FLASH). RARE sequence provides nice images in less than 400 ms with only small amounts of gas; EPI is fast but it is hindered by several artefacts such as the Maxwell term artefact; both these sequences are intrinsically limited to a spatial resolution above 5 mm in vivo; FLASH sequence can provide a better resolution but it is less efficient with regards to signal to noise ratio. Low field can be attractive in the hyperpolarised case because the signal to noise ratio is independent of the main magnetic field on a very large range. NMR and MRI CPMG measurements of gas diffusion in lungs are used to underline the alveolar restriction. [Text] [View with Perseus links] (0.10)

2. SCHLOSSER, Nicolas; Etude et realisation de micro-pieges dipolaires optiques pour atomes neutres: Les atomes neutres pieges sont des candidats potentiels pour l'implementation de portes logiques quantiques. Dans ce contexte, cette etude porte sur la realisation d'un piege dipolaire optique de si petite taille qu'il ne puisse contenir qu'un atome unique. Pour cela, il est necessaire de focaliser tres fortement un laser a l'endroit ou l'on desire capturer les atomes. L'experience s'articule donc autour d'un objectif de microscope de grande ouverture numerique, entierement concu et realise au laboratoire. Cette optique est utilisee pour faire focaliser un laser au centre d'un piege magneto-optique, reservoir d'atomes froids alimentant le piege dipolaire ainsi cree. Le dispositif d'observation des atomes pieges est base sur le meme objectif, qui collecte, avec une grande efficacite, la fluorescence des atomes pieges et en fait l'image sur une camera CCD ou une photodiode a avalanche. La resolution spatiale du dispositif utilisant la camera permet d'obtenir une image des atomes captures, alors que l'on utilise la rapidite de la photodiode a avalanche pour les etudes de la dynamique du piege avec une bonne resolution temporelle. Apres une description detaillee de ce dispositif experimental, nous montrons qu'il est possible de realiser des micro-pieges dipolaires optiques, de quelques microns cube et contenant une dizaine d'atomes. L'etude de la dynamique de chargement et de la duree de vie de ces pieges revele egalement la presence de processus de collisions a deux corps. Nous montrons ensuite qu'en diminuant le taux de chargement il est possible d'observer, en temps reel, un atome unique piege pendant quelques secondes. Dans ce regime, un processus de "blocage collisionnel" limite ce nombre d'atome a un. Pour finir, nous decrirons la mise en place d'un double piege dipolaire, dans lequel on peut pieger un atome unique dans chaque site. Ce dispositif ouvre la voie vers l'etude de l'interaction entre atomes pieges individuellement. ---------- Neutral atoms are possible candidates for the implementation of quantum gates. In this context, the subject of this study is the realization of optical dipole traps, small enough to contain only a single atom. In order to obtain the dipole trap, we need to focus strongly a laser beam at the point where we want to trap the atoms. The central part of the experiment is an home-built microscope objective, with a great numerical aperture. This system focus the light in the center of a Magneto-Optical Trap which is the source of cold atoms used to load our dipole trap. The imaging set-up is based on the the same objective. It collects the fluorescence light coming from trapped atoms with a great efficiency and images them either on a CCD camera or an avalanche photodiode. The spatial resolution of the system using the camera gives images of the atom cloud, and the avalanche photodiode allows us to study the dynamic of the trap with a good time resolution. After the description of the experimental set-up, we demonstrate the realization of microscopic optical dipole traps with a volume of a few cubic microns and containing a few atoms. The study of loading process and the lifetime reveals the presence of two body collisions. Then, with a reduced loading rate, we can see, in real time, single atoms arriving one by one in the trap. In this regime, a process of "collisionnal blockade" limits the atom number to one. Finally, we present a realization of a double dipole trap, in which we can trap two individual atoms in each site.

1. Redfearn, Christian L., Englund, Peter, Quigley, John M.; Do Housing Transactions Provide Misleading Evidence about the Course of Housing Values?: Estimates of the prices of housing and the value of the stock are derived from observations on housing transactions. These transactions may well be a non-random sample of the underlying population of dwellings. For example, it is widely thought that smaller "starter homes" sell more frequently than more expensive properties and that the frequency of transactions on high-valued properties varies over the business cycle. This paper considers the importance of these selectivity issues in making imputations about housing price trends. We estimate a model of housing price determination and of the nonrandom selection of observed transactions. We analyze the factors affecting the probabilities that transactions on different houses will be observed, and we estimate the effect of these factors upon housing prices. The analysis considers a variety of plausible selection models. For each of the alternatives, the estimated effect of selectivity upon housing price calculations is quite substantial. The analysis is based on a unique body of data containing observations of all house sales in Sweden during the period 1981- 1993. [Text] [View with Perseus links] (1.74)

2. Rogoff, Kenneth, Obstfeld, Maurice; The Six Major Puzzles in International Macroeconomics: Is There a Common Cause?: The central claim in this paper is that by explicitly introducing costs of international trade (narrowly, transport costs but more broadly, tariffs, nontariff barriers and other trade costs), one can go far toward explaining a great number of the main empirical puzzles that international macroeconomists have struggled with over twenty-five years. Our approach elucidates J. McCallum's home bias in trade puzzle, the Feldstein-Horioka saving-investment puzzle, the French-Poterba equity home bias puzzle, and the Backus-Kehoe-Kydland consumption correlations puzzle. That one simple alteration to an otherwise canonical international macroeconomic model can help substantially to explain such a broad arrange of empirical puzzles, including some that previously seemed intractable, suggests a rich area for future research. We also address a variety of international pricing puzzles, including the purchasing power parity puzzle emphasized by Rogoff, and what we term "the exchange rate disconnect puzzle." The latter category of riddles includes both the Meese-Rogoff exchange rate forecasting puzzle and the Baxter-Stockman neutrality of exchange rate regime puzzle. Here, although many elements need to be added to our extremely simple model, trade costs still play an essential role. [Text] [View with Perseus links] (1.38)

3. Spiegel, Matthew; Housing Return and Construction Cycles: This paper presents a model that derives both housing returns and housing construction patterns from events in the real economy. The value of a home, unlike the value of many other financial assets, depends upon the care its owner exerts on upkeep. Within the model banks respond to this moral hazard problem by restricting the size of the loans they are willing to issue. As a result housing prices no longer follow a random walk, but rather are tied to changes in the endowment process which are both predictable and time varying. That is, in some states of nature homeowners expect to earn an above market return on their housing purchase while in others they expect to earn a below market return. Developers in the model are fully cognizant of the housing price process and react accordingly. The result is a construction cycle that seems at odds with conventional wisdom. When endowments are growing quickly (a city with a rapidly growing economy) housing prices exhibit above market expected returns. However, since housing prices are expected to increase faster than the rate of interest, developers delay construction. Thus, during periods of rapid expected economic growth housing construction ceases until one reaches the crest whereupon development booms. In response housing supplies dwindle during economic booms (as homes deteriorate) and then increase when the boom ends. [Text] [View with Perseus links] (0.86)

1. Marcio Paredes, M A A Meireles; PREDICTIONS OF BRANCHED AND CYCLIC CHAIN PROPERTIES FROM LINEAR CHAIN PROPERTIES: MOLECULAR SIMULATION AND THERMODYNAMIC POLYMERIZATION THEORY: Predictive and reliable methods to obtain thermodynamic properties of natural products are very important for food engineering process design, including supercritical extraction. In this work we have studied the prediction of thermodynamic properties based on the molecular structure, calculating properties of branched and cyclic molecules from linear chains properties. The thermodynamic model used is based on the thermodynamic polymerization theory (TPT), where the chain segments interact via the Square-Well potential. In the TPT approach, the properties of linear, cyclic, and branched homo-segment chains can be calculated from the non-bonded macroscopic segment properties and from the segment-segment radial distribution function at the contact point (RDF). For this reason, Monte Carlo Canonical simulations were performed to evaluate the RDF between different segment types in linear chains, and to obtain the branched and cyclic chain properties. In order to analyze the results, cyclic and branched paraffin properties were calculated from the properties of a homologue series of normal alkanes. The predictions for branched chain properties agree very well with the experimental data. For cyclic chains, the predictions of saturation pressures are reasonable, while the predictions for saturated liquid densities are not good. [Text] [View with Perseus links] (0.28)

1. Skoyles, John R.; Human evolution expanded brains to increase expertise capacity, not IQ.: Why do modern humans have larger brains than earlier people such as Homo erectus? As large brains cause problems in childbirth, infancy and locomotion, the advantage they offer must be substantial. This advantage might be associated with increased IQ, but there is a problem: evidence from MRI volumetric surveys, microcephaly and hemispherectomy shows that there exist individuals with psychometrically normal IQ but Homo-erectus-sized brains. Why did evolution increase brain size (with its associated costs) when humans (as these individuals demonstrate) can have normal IQ without bigger brains? I propose that the advantage may be related to increased capacity for an aspect of intelligent behaviour not measured by IQ tests but critical to the survival of our simple hunter-gatherers ancestors: the capacity to develop expertise.

2. Dennett, Daniel C; Did HAL Commit Murder?: The first robot homicide was committed in 1981, according to my files. I have a yellowed clipping dated 12/9/81 from the Philadelphia Inquirer--not the National Enquirer--with the headline: Robot killed repairman, Japan reports The story was an anti-climax: at the Kawasaki Heavy Industries plant in Akashi, a malfunctioning robotic arm pushed a repairman against a gearwheel-milling machine, crushing him to death. The repairman had failed to follow proper instructions for shutting down the arm before entering the workspace. Why, indeed, had this industrial accident in Japan been reported in a Philadelphia newspaper? Every day somewhere in the world a human worker is killed by one machine or another. The difference, of course, was that in the public imagination at least, this was no ordinary machine; this was a robot, a machine that might have a mind, might have evil intentions, might be capable not just of homicide but of murder.

3. Deecke, L, Lang, W, Beisteiner, R, Lindinger, G, Cui, R Q; Movement-Related Potentials and Magnetic Fields: New Evidence for SMA Activation Leading MI Activation Prior to Voluntary Movement: Movement is the essence of life. Without movement one cannotachieve anything. Consequently, during evolution, movement has been optimized to highest levels of precision. Visible sign of the evolution of movement is that more and more brain has been assigned for motor purposes. A carnivores motor cortex is just a dimple' in its brain supported by merely a minimal frontal cortex. In the primate, the dimple evolved into a motor strip and shifted from an anterior to a central position, in order to accommodate more and more frontal brain. Homo sapiens neanderthalensis with his sloping forehead still had less frontal cortex than Homo sapiens sapiens. In the latter, about half the cortex is pre-rolandic, assigned to motor purposes in the broader sense, i.e. including areas that supply to motor such as premotor, prefrontal, etc. areas. These frontal supplier areas to motor are involved in functions such as motivation, preparation, volition, will, planning, foresight, active anticipation, precaution, intent to act, purposefulness, goal-directedness, etc. i.e. all these functions are frontal in location, and the function of the frontal lobes seems to be almost entirely behavour-related including - in man - all the future-related behavioural aspects. A special role may be assigned to the frontomesial cortex including the supplementary motor area (SMA) and the cingulate motor area (CMA). The brain apparatus supporting motor is among the most recent and highly organized cerebral structures (neoneocortex), and the corticalization of movement developed in a saltatory way in primate phylogenesis. There are many movements man can perform, but basically there are only two primordial categories of movements: Self-initiated voluntary movements = actions and responsive (externally triggered) movements = re-actions. The first category is preceded by a Bereitschaftspotential, the latter occurs between S1 and S2 of a re-action paradigm (Walter et al. 1964). Regarding the BP, recent evidence using multichannel (64) DC-EEG (time constant [tau] = [infinity]) computer-assisted amplification proved that the earliest activity occuring is over the SMA/CMA. Only later comes the primary motor area (MI) into play. This was also shown using current source density techniques (laplacians with spline interpolation), multichannel (143) MEG and FMRI.

1. Bennett, Elizabeth; Institutions, Economics, and Conflicts: Fisheries Management Under Pressure: (in English) "Poorly defined property rights, increasing effort and decreasing catches are resulting in conflict in fisheries throughout the world. While these effects are common and well documented in highly regulated fisheries in the European Union (conflicts over allocation of quota for example) and North America (for example conflicts over access to salmon stocks between the USA and Canada); the effects upon fisheries in developing countries, while under-researched are invariably more dramatic and can have long-term implications for the promotion of sustainable livelihoods. "While there is as yet little evidence of a sharp increase in natural resource conflicts (Hussein, 1999) it is apparent, however, that the consequences of conflict in the management of natural resources are becoming more detrimental to long-term sustainable exploitation and are effecting an increasingly large number of people (Olomola, 1998; Homer-Dixon, 1994; Streiffeler, nd; Myers, 1987). Although there is an extensive literature on natural resource conflicts, little work has been done on a) analysing the causes of conflict beyond the case-study arena or b) applying economic tools to the study of conflict. In an attempt to redress the balance, this paper sets out some initial findings from an on-going study into the management of conflict in tropical fisheries. Drawing on New Institutional Economics and common property resource management theory, it analyses how and why fisheries institutions adapt to changing circumstances and the role of conflict in the process. Using evidence from Ghana it examines the emergence of fisheries management institutions under differing access regimes and analyses the factors which appear to have influenced institutional change. "The paper argues that conflict can be the result of rising transaction costs and the inability of natural resource institutions to manage these changes. It also argues that conflict can be both a positive and negative force and should not necessarily be eliminated altogether. "The paper is divided into four sections. First, it locates fishing as an economic activity within developing countries and looks at the interactions between local, national and international policy objectives and how these can impact upon the development and exploitation of the resource. In the second section, conflicts are described and why they emerge in natural resources management is discussed. Focusing on the role of institutions it looks at how changes in institutions might affect the management of common property resources. Section three draws on initial findings from field research conducted in Ghana between March and May 2000. In the final section, the paper presents a number of conclusions as to the process of conflict formation and the possibilities for managing it." [Text] [View with Perseus links] (0.82)

2. Hartmann, Wolf D., Campelo, Carlos Magno Feijo; Ambivalent Enforcers, Rules and Conflicts in the Co-Management of Brazilian Reservoir Fisheries: (in English) Authors' Introduction: About 12% of Brazil's total area, comprising nine states in the country's Northeast, is semi-arid. Droughts, which in the past have periodically wiped out large populations of local residents and driven millions from their homes, have been a frequent phenomenon well into our days. The damming of rivers and the creation of reservoirs has been and still is the state's major policy instrument against droughts. Today there are about 60,000 reservoirs with an inundated area of circa 800,000 ha in the so-called 'Polygon of Droughts.' Their main purposes are water storage for agricultural and domestic use during the annual dry seasons and prolonged periods of drought, river flow regulation to allow for irrigated cultivation of perennial crops, and fisheries and aquaculture. While some claim that the hydraulic infrastructure provided in the past has been insufficient and almost insignificant in the face of existing necessities (MACEDO 1996), other have pointed out that engineering measures per se are not sufficient to resolve water scarcity and its effects on the rural economy (KEMPER 1996). What is needed, they argue, are institutional improvements in aquatic resources use and management. This has become even more pressing as the National Department of Works Against Droughts --DNOCS, the federal organisation responsible for constructing and operating large reservoirs as well as managing the natural resources associated with it, has been forced to steadily withdraw from those tasks over recent years, due to drastic cuts in finance and personnel. Emphasis is now being given to participatory and integrated forms of catchment-wide aquatic resources management. In Brazil's Northeast, the Ceara Reservoir Fisheries Project -- PAPEC has been among the first to establish co-management of natural resources on a catchment basis. At present, PAPEC is considered a reference project for similar endeavours by various organisations on state and regional levels. Yet, its outcomes and sustainability are now endangered by conflicts among resource users who find it difficult to implement their own management rules and regulations. These conflicts have come as a surprise: A high degree of participation of users in resource management decision-making and the homogeneity of the user group suggested a less conflicting implementation of management proposals. The paper focuses on the analysis of the conflict and on the social and ecological dynamics influencing conflict management. It also describes and analyses the ambivalence in efforts shown and results obtained by resource users in enforcing rules set by themselves." [Text] [View with Perseus links] (0.29)

3. Morgan, Betty; The Language of 'The Commons' in Low Income Housing Communities: Common Property Theory and the Development of a Progressive U.S. Federal Housing Policy: (in English) (From the Author's Abstract) While historically, public housing facilities in the United States have never been planned or managed from the perspectives of common property theory, one contemporary approach to the provision of public housing is to plan or manage public housing installations as 'communities of the whole.' (Pollack, 1997) This paper will examine one recent effort to apply the theoretical concepts of New Urbanism to the reinvention of a public housing facility located in the Southern United States, looking at the effort as a means for expanding housing options while creating a new sense of community. What emerges from this process, the paper argues, is the need for and applicability of common property theories and concepts to facilitate the conceptual understandings of those affected by the transition. Building upon the work of 1997 IASCP paper authors Bernard Freidan, Rutherford Platt, and Patricia Pollack (Is There an Urban Commons in the United States Panel), this report extends their efforts by developing a case study of the 1997 effort of the Greensboro, North Carolina, Public Housing Authority to transform one public housing community, Morningside Homes, and reports the results of an innovative design charette experience which combined unprecedented levels of community participation with cutting edge technical expertise in an effort to reinvent the public housing community concept. Among the numerous theoretical and conceptual needs which emerged from this innovative planning process, was the almost immediate recognition that public housing conversion, at this scale, will require attending to many of the same problems that have historically been solved through common property regimes.... This paper reports on the extraordinary process of planning, design, resolution and invigoration which transformed the Morningside community and describes the residents' process of establishing their own common property regime. Finally, nearing the project's first anniversary, the paper explores the success the project has achieved in pressing federal agencies, local governments, nonprofit and community organizations and developers to create innovative ways of redistributing rights and responsibilities for common spaces, land, infrastructure, and buildings, in this attempt to make the transition to new forms of public and private activities."

2. Lukesh, Susan S.; E-mail and Potential Loss to Future Archives and Scholarship or The Dog that Didn't Bark: This paper explores the preservation of electronic correspondence - a small subset of the large and varied area of the preservation of electronic documents. Discussions of preservation in the literature today and briefly reviewed below focus on electronic publications, Web sites and even listservs - all more easily seen as 'public' areas and, we hope, someday susceptible to broad preservation efforts. Personal correspondence among scholars, scientists, and others, unless deliberately retained in one form or another, does not seem to be part of any preservation plan and its preservation receives little attention in the literature. These resources are too often on individual computers or on computers at a scholar's home institution. The premise of this paper is that if electronic correspondence, personal e-mail, is not retained, there will be significant loss to future understanding of the work of today's scholars', to historians' work in general and to our collective memory. "The ability of a culture to survive into the future depends on the richness and acuity of its members' sense of history" Preserving Digital Information, Introduction) The problem is not only a subset of the problem of digital preservation in general but also a subset of technology's future impact on scholarly research methods.

We investigated age and sex composition, population density and stabil- ity, rates of reproduction and mortality, health status, territorial behaviour, kinship re- lation, and the influence of neutering on individual behaviour and population devel- opment. Altogether we observed 75 cats within 42 months. 25 to 35 cats lived simul- taneously in the study area, additionally we found 10 transient animals per year on average. The resident cats lived in two genetically distinct subpopulations. Uncas- trated adult males had larger home ranges (20-66 ha) than castrated males, cas- trated and uncastrated females and subadult cats (0,5-7,5 ha). Mortality rate of resi- dent cats was 25 % per year. Vacancies were filled by own kittens. The number of uncastrated adult tomcats was constant throughout the study period, castration and death of stud males were compensated by immigration of unknown tomcats. After the castration of all females in one subpopulation population density declined, even though immigration of unknown cats increased significantly. [Text] [View with Perseus links] (0.27)

3. Hosang, Maik; Homo sapiens integralis: Transdisziplinare Begriffe fur eine nachhaltige Entwicklung: (in German) In the last centuries enormous means for the eleviation of human existence were developed. These means now threaten to choke their human creators if they dont develop their economical, social and spiritual patterns of selforganisation. Necessary is a transcendence of the splits which limit the human theory and practice, an integration of the real interacting but in our mind widely seperated spheres of environment and inner life, of theory and practice, of economy and spirit, of rationality and intuition, of management and art, of love and work and so on. The differentation of these spheres once was nessecary to liberate the human evolution from the narrow limits of natural environment and primary groups respectively religious dogmas. Thats why the solution is not going back to natural or premodern conditions but integrating a new, and more differenciated consciosness. It needs a new sight and new concepts for a new, holistic and integral understanding of human reality. This book analyzes this historical situation of mankind and develops new theoretical and practical concepts through a synthesis of natural, social and spiritual sciences. The core is the theoretical foundation of the subjective assumtions as primary conditions for the beginning of a sustainable development. [Text] [View with Perseus links] (0.14)

1. Barreto, Gustavo A.; Building Community: An Environmental Approach to Crime Prevention.: (in English) Crime cannot be understood as a single-solution problem. Participation of the community is important to complement and make more efficient any program of crime control by police authorities or any other law enforcement agency. This thesis is intended to create consciousness among designers of the urban environment of their social role. Cities must include places to promote community interaction and formation of social bonds. As social bonds among residents increase, and bonds with the place begin building a sense of territoriality in the community, the residents become active defenders of the place against crime. A theory summary presents different and complementary points of view, some focused directly to urban and landscape design such as those stated by Jane Jacobs, Clare Cooper Marcus, Donald Appleyard, and Oscar Newman. Others focused to social and psychological aspects of the relation between humans and environment, for example those presented by Erving Goffman, Edward Hall, Amos Rapaport, Irwin Altman, and Setha Low. A field study is presented to complement the theory review. It was based on two inner city neighborhoods in Orlando, Florida. The data used came from Orlando Police Department, FBI, and U.S. Department of Justice crime and victimization reports. The population characteristics were analyzed based on the 2000 U.S. Census. From the study, a general conclusion is that social characteristics of the population in any given neighborhood such as poverty, high percentage of broken families, unemployment, social heterogeneity, large numbers of young population, and large proportion of rented homes create environments highly susceptible of crime. But social characteristics are not the only aspects determining crime. Physical layout of the neighborhood plays also an important role in preventing or promoting crime. In spite of the fact that both neighborhoods had similar social characteristics, crime was considerably higher in the neighborhood where the physical structure neglected possibilities for neighbors to interact and use public areas. Theories and other information presented is finally synthesized into design guidelines, which are related specifically to the function of landscape architects and other designers as shapers of cities and societies.

2. Watson, Margaret M.; Doing Homework: Negotiations of the Domestic in Twentieth-Century Novels of Teaching: (in English) In this project, I analyze seven twentieth-century novels of teaching in order to investigate how notions of home and school are constructed, connected, and perpetuated in popular teaching narratives. Images of teachers in much of this centurys fiction often rest on views of the school as home that are derived from stereotypes of gender, race, and nationalitystereotypes that can be both inaccurate and repressive. For this reason, I examine these texts in light of how they negotiate school space with domestic space (domestic both as personal or familial, and as public or national). I contend that many of these narratives offer little more than simplistic, nostalgic views of what home/school space can be, and even fewer question the very equation of school as home. In those narratives that do probe the school/home connection, the teacher-protagonists often fail to emerge as the sentimental heroes that the teachers of the more conventional novels prove to be. Nevertheless, I argue that the most promising depictions of teachers and their work are those that acknowledge and engage the rich complexities of home and its (sometimes problematic) relation to the classroom, for the very tensions and conflicts that problematize the schools classification as a domestic safe haven are the very tools that can facilitate growth, learning, and self-discovery. The approach for my analysis draws from feminist and cultural studies, as well as educational history. The works I discuss include the following: The Blackboard Jungle; Good Morning, Miss Dove; To Sir, With Love; Spinster; The Prime of Miss Jean Brodie; Up the Down Staircase; and Election.

3. Poston, Vicky Lynn; A Descriptive study of At Risk Mothers' Interactions With Their Children: (in English) The purpose of this study was to describe the home environment and nature of mother-child interactions of low-income African-American mothers. The subjects included eight mother-child dyads. All of the mothers were single, African-American and working toward a G.E.D. Their age ranged from 17-30 years of age. Their children ranged in age from 24-67 months. A home visit and a mother-child play session that was collected at the childrens child care center were utilized to collect the data. The findings from the current study were consistent with the literature reviewed in that most of the mothers produced a decreased speech rate, decreased number of word types, decreased percentage of affirmatives, and an increased percentage of controlling behaviors compared to data from middle socioeconomic status mothers. It is important to note, however, that the mothers did vary in their language behaviors. Although previous studies have found significant differences between the language behaviors of lower socioeconomic status mothers when compared to upper-middle class and professional mothers, the results of this study indicate that a range of variability does exist among the former group of mothers.

1. Al-Muhtadi, Jalal, Anand, Manish, Mickunas, M. Dennis, Campbell, Roy H.; Secure Smart Homes using Jini and UIUC SESAME: In this paper, we discuss our approach to constructing a dynamic and secure "Smart Home" environment and tackling the challenges associated with it. "Tiny UIUC SESAME" is a lightweight Java-implementation of a subset of SESAME. SESAME is an extension to Kerberos that supports public key technologies, access control, and delegation of access rights. We discuss our Tiny UIUC SESAME and how it could be integrated with handheld and consumer devices. With the current advancements in computing power and network technology, the concept of fully automated "smart" homes is not far fetched. Jini technology from Sun Microsystems provides the necessary facilities for creating "network plug and play" devices, which when connected to a network, announce their presence and enable network users to exploit these devices remotely. Once all devices in a household are automated and connected through a network; authentication, security and access control become important and challenging issues to consider. Since Jini provides APIs, protocols, and conventions that handle the common parts of distributed devices, building a Smart Home environment with these tools is fairly straightforward. We have implemented such a dynamic "Smart Home" environment using Jini technology, securing the environment with our Tiny UIUC SESAME, our secure network authentication system. <P> [Text] (3.09)

3. Basri, R., Rivlin, E., Shimshoni, I.; <i>Visual Homing: Surfing on the Epipoles</i>: We introduce a novel method for visual homing. Using this method a robot can be sent to desired positions and orientations in 3-D space specified by single images taken from these positions. Our method is based on recovering the epipolar geometry relating the current image taken by the robot and the target image. Using the epipolar geometry, most of the parameters which specify the differences in position and orientation of the camera between the two images are recovered. However, since not all of the parameters can be recovered from two images, we have developed specific methods to bypass these missing parameters and resolve the ambiguities that exist. We present two homing algorithms for two standard projection models, weak and full perspective. <p> Our method determines the path of the robot on-line, the starting position of the robot is relatively not constrained, and a 3-D model of the environment is not required. The method is almost entirely memoryless, in the sense that at every step the path to the target position is determined independently of the previous path taken by the robot. Because of this property the robot may be able, while moving toward the target, to perform auxiliary tasks or to avoid obstacles, without this impairing its ability to eventually reach the target position. We have performed simulations and real experiments which demonstrate the robustness of the method and that the algorithms always converge to the target pose. [Text] [View with Perseus links] (2.52)

1. Blochwitz, Jan Dipl.-Phys.; Organic light-emitting diodes with doped charge transport layers, alternative/translated: Organische Leuchtdioden mit dotierten Ladungstragertransportschichten: Technische Universitat Dresden, Mathematik und Naturwissenschaften, Physik, Institut fur Angewandte Photophysik (IAPP); (in English) Organic dyes with a conjugated pi-electron system usually exhibit semiconducting behavior. Hence, they are potential materials for electronic and optoelectronic devices. Nowadays, some applications are already commercial on small scales. Controlled doping of inorganic semiconductors was the key step for today's inorganic semiconductor technology. The control of the conduction type and Fermi-level is crucial for the realization of stable pn-junctions. This allows for optimized light emitting diode (LED) structures with operating voltages close to the optical limit (around 2.5V for a green emitting LED). Despite that, organic light emitting diodes (OLEDs) generally consist of a series of intrinsic layers based on organic molecules. These intrinsic organic charge transport layers suffer from non-ideal injection and noticeable ohmic losses. However, organic materials feature some technological advantages for device applications like low cost, an almost unlimited variety of materials, and possible preparation on large and flexible substrates. They also differ in some basic physical parameters, like the index of refraction in the visible wavelength region, the absorption coefficient and the Stokes-shift of the emission wavelength. Doping of organic semiconductors has only been scarcely addressed. Our aim is the lowering of the operating voltages of OLEDs by the use of doped organic charge transport layers. The present work is focused mainly on the p-type doping of weakly donor-type molecules with strong acceptor molecules by co-evaporation of the two types of molecules in a vacuum system. In order to understand the improved hole injection from a contact material into a p-type doped organic layer, ultraviolet photoelectron spectroscopy combined with X-ray photoelectron spectroscopy (UPS/XPS) was carried out. The experimental results of the UPS/XPS measurements on F4-TCNQ doped zinc-phthalocyanine (ZnPc) and their interpretation is given. Measurements were done on the typical transparent anode material for OLEDs, indium-tin-oxide (ITO) and on gold. The conclusion from these experiments is that (i) the Fermi-energy comes closer to the transport energy (the HOMO for p-type doping), (ii) the built-in potential is changed accordingly, and (iii) the depletion layer becomes very thin because of the high space charge density in the doped layer. The junction between a doped organic layer and the conductive substrate behaves rather similar to a heavily doped Schottky junction, known from inorganic semicondcutor physics. This behavior favors charge injection from the contact into the organic semiconductor due to tunneling through a very small Schottky barrier (quasi-ohmic contact). The performance of OLEDs with doped charge transport layers improves successively from a simple two-layer design with doped phthalocyanine as hole transport layer over a three-layer design with an electron blocking layer until OLEDs with doped amorphous wide gap materials, with and without additional electron injection enhancement and electron blocking layers. Based on the experience with the first OLEDs featuring doped hole transport layers, an ideal device concept which is based on realistic material parameters is proposed (blocking layer concept). Very high efficient OLEDs with still low operating voltage have been prepared by using an additional emitter dopant molecule with very high photoluminescence quantum yield in the recombination zone of a conventional OLED. An OLED with an operating voltage of 3.2-3.2V for a brightness of 100cd/m2 could be demonstrated. These results represent the lowest ever reported operating voltage for LEDs consisting of exclusively vacuum sublimed molecular layers. The current efficiency for this device is above 10cd/A, hence, the power efficiency at 100cd/m2 is about 10lm/W. This high power efficiency could be achieved by the use of a blocking layer between the transport and the emission layer., Organische Farbstoffe mit einem konjugierten pi-Elektronen System zeigen uberwiegend ein halbleitendes Verhalten. Daher sind sie potentielle Materialien fur elektronische und optoelektronische Anwendungen. Erste Anwendungen in Flachbildschirmen sind bereits in (noch) geringen Mengen auf dem Markt. Die kontrollierte Dotierung anorganischer Halbleiter bereitete die Basis fur den Durchbruch der bekannten Halbleitertechnologie. Die Kontrolle des Leitungstypes und der Lage des Fermi-Niveaus erlaubte es, stabile pn-Ubergange herzustellen. LEDs konnen daher mit Betriebsspannungen nahe dem thermodynamischen Limit betrieben werden (ca. 2.5V fur eine Emission im grunen Spektralbereich). Im Gegensatz dazu bestehen organische Leuchtdioden (OLEDs) typischerweise aus einer Folge intrinsischer Schichten. Diese weisen eine ineffiziente Injektion aus Kontakten und eine relative geringe Leitfahigkeit auf, welche mit hohen ohmschen Verlusten verbunden ist. Andererseits besitzen organische Materialien einige technologische Vorteile, wie geringe Herstellungskosten, grosse Vielfalt der chemischen Verbindungen und die Moglichkeit sie auf flexible grosse Substrate aufzubringen. Sie unterscheiden sich ebenso in einigen fundamentalen physikalischen Parametern wie Brechungsindex, Dielektrizitatskonstante, Absorptionskoeffizient und Stokes-Verschiebung der Emissionswellenlange gegenuber der Absorption. Das Konzept der Dotierung wurde fur organische Halbleiter bisher kaum untersucht und angewandt. Unser Ziel ist die Erniedrigung der Betriebsspannung herkommlicher OLEDs durch den Einsatz der gezielten Dotierung der Transportschichten mit organischen Molekulen. Um die verbesserte Injektion aus der Anode in die dotierte Lochertransportschicht zu verstehen, wurden UPS/XPS Messungen durchgefuhrt (ultraviolette und Rontgen-Photoelektronenspektroskopie). Messungen wurden an mit F4-TCNQ dotiertem Zink-Phthalocyanin auf ITO und Gold-Kontakten durchgefuhrt. Die Schlussfolgerungen aus den Experimenten ist, das (i) die Fermi-Energie sich durch Dotierung dem Transportniveau (also dem HOMO im Falle der vorliegenden p-Dotierung) annahert, (ii) die Diffusionspannung an der Grenzflache durch Dotierung entsprechend verandert wird, und (iii) die Verarmungszone am Kontakt zum ITO sehr dunn wird. Der Kontakt aus organischem Material und leitfahigem Substrat verhalt sich also ganz analog zum Fall der Dotierung anorganischer Halbleiter. Es entsteht ein stark dotierter Schottky-Kontakt dessen schmale Verarmungszone leicht durchtunnelt werden kann (quasi-ohmscher Kontakt). Die Leistungseffizienz von OLEDs mit dotierten Transportschichten konnte sukzessive erhoht werden, vom einfachen 2-Schicht Design mit dotiertem Phthalocyanine als Lochertransportschicht, uber einen 3-Schicht-Aufbau mit einer Elektronen-Blockschicht bis zu OLEDs mit dotierten 'wide-gap' Lochertransport-Materialien, mit und ohne zusatzlicher Schicht zur Verbesserung der Elektroneninjektion. Sehr effiziente OLEDs mit immer noch niedriger Betriebsspannung wurden durch die Dotierung der Emissionsschicht mit Molekulen erhohter Photolumineszenzquantenausbeute (Laser-Farbstoffe) erreicht. Eine optimierte LED-Struktur weist eine Betriebsspannung von 3.2-3.2V fur eine Lichtemission von 100cd/m2 auf. Diese Resultate entsprechen den zur Zeit niedrigsten Betriebsspannungen fur OLEDs mit ausschliesslich im Vakuum aufgedampften Schichten. Die Stromeffizienz liegt bei ca. 10cd/A, was einer Leistungseffizienz bei 100cd/m2 von 10lm/W entspricht. Diese hohe Leistungseffizienz war nur moglich durch die Verwendung einer Blockschicht zwischen der dotierten Transportschicht und der Lichtemissions-Schicht. Im Rahmen der Arbeit konnte gezeigt werden, dass die Dotierung die Betriebsspannungen von OLEDs senken kann und damit die Leistungseffizienz erhoht wird. Zusammen mit einer sehr dunnen Blockschicht konnte einen niedrige Betriebsspannung bei gleichzeitig hoher Effizienz erreicht werden (Blockschicht-Konzept). [Text] (0.81)

2. Jung, Thomas; Wovon das Schlafzimmer ein Zeichen ist: (in German) In der 'Erlebnisgesellschaft' ist die Art und Weise des Wohnens ein wichtiges Feld der alltagsasthetischen Selbstinszenierung. In diesem Prozess des 'Impression Management' ist langst auch die Gestaltung des Schlafzimmers hineingezogen worden. Deshalb gilt selbst fur diesen Intimbereich der Satz: "Sag mir, wie Dein Schlafraum gestaltet ist, ich sage Dir, wer Du bist." Allerdings ist auch die Gestaltung des eigenen Lebensstils im Bereich der Schlafraumkultur gesteuert von der Angebotsseite und ihren Vermittlern: den Wohnzeitschriften, Einrichtungshausern, der Werbung etc. Auf welche Weise diese Vermittlung von Lebensstilen geschieht, ist im Rahmen einer von der der Deutschen Forschungsgemeinschaft geforderten kultursoziologischen Studie untersucht worden. Die Ergebnisse verraten, wovon das Schlafzimmer ein Zeichen ist. In today's "experience society" the way one lives at home is a major area for the aesthetic staging of one's own person. The furnishing of the bedroom has long since been included in this process of "impression management." Thus even the most intimate area tells tales: "Tell me what your sleeping room is like, and I will tell you who you are." But the fashioning of the individual's lifestyle in the bedroom is channeled by what is on offer and its agents - home magazines, furniture stores, advertising, etc. How this conveying of life styles occurs has been investigated in a study financed in part by the German Research Association (DFG). The results reveal what the bedroom is a sign of. [Text] (0.63)

1. Grossmann, Volker; Anwendung der Roentgenbeugung zur Analyse der strukturellen Eigenschaften von homo- und heteroepitaktischen Halbleiterschichten auf ZnSe-Basis: (in German) An asymmetric relaxation was observed for the azimuth directions [110] and [1-10]. The dislocation density before and after heating was estimated from the diffuse scattering. Values of 3.3 *10^3 /cm and 13 *10^3 /cm were derived for the [110]-azimuth direction. The residual strain of single ZnSe layers on GaAs substrates due to work hardening was found to be 2.0 *10^(-4) in agreement with theoretical predictions. A critical layer thickness for work hardening of about 2.0 m was derived. Comparing the thermal expansion of homo- and heteroepitaxially grown device relevant MgZnSSe layers showed nearly equal thermal expansion coefficients of both layer types. These measurements could be utilized to extrapolate the thermal expansion coefficient of MgSe in the zincblende structure. A value of 4.2 * 10^(-6) /K was derived for the temperature range from 300 K to 500 K. In the second part of the work, the influence of two different growth start procedures on the structural perfection of homoepitaxially grown ZnSe-based layers is discussed. A drastic increase in crystalline quality of the epitaxial layers resulted from various changes in growth procedure. The most important was the introduction of an {\em in situ} hydrogen plasma cleaning of the ZnSe substrates prior to the ZnSe growth. It provides a substrate surface free from contamination enabling to reduce the defect densities in the epitaxial layers by two orders of magnitude. [Text] (0.38)

1. Wood, Rebecca S. Jr.; Housing Market Choice Patterns of Single Women Homeowners: Kathleen R. Parrott, Irene E. Leech, Rosemary Carucci Goss, Jesse C. Arnold, Dr. Julia O. Beamish; (in English) Housing researchers are aware of the lower homeownership rates and other housing problems of single women but there is very little research focusing on single women homeowners or the characteristics of the housing they buy. Also, since a wide body of research can be found that examines determinants of homeownership for various population groups, the importance of this study was in its focus on single women homeowners and the characteristics of their housing rather than the determinants of ownership for this group. Using data from the 1993 American Housing Survey (AHS), the study sample consisted of 639 women homeowners who were either widowed, divorced, separated, or never-married, and who did not own their previous residence. The study's purpose was to construct a profile of single women home- owners that included a description of their demographic and housing characteristics, the means by which they acquired their homes, and the changes made in their housing when they became homeowners. Additionally, this study examined which demographic and previous housing characteristics of this group were related to the housing characteristics of their present homes. Descriptive results from this study suggested that single women homeowners are primarily middle aged without young children at home, earn moderate incomes, and that the largest proportion of them live in the South and metropolitan areas. When compared to homeowners in general, single women homeowners' homes cost less and represented a higher proportion of attached and mobile home units. The results also showed that single women used low-down payment financing instruments to a lesser degree than did all homeowners. Results from statistical analyses suggested that significant relationships exist between single women homeowners' housing characteristics, and a) their demographic characteristics, b) their previous housing characteristics, and c) their reasons for moving and selecting their current homes and neighborhoods. Another key finding was that single women homeowners of varying marital status differed in their present and previous housing characteristics and their reasons for selecting the current home. The results of this study support suggestions made by other researchers that examining differences not only by gender but also by the variations in marital status will help to clarify and add to the knowledge of housing and its relevance to populations of varying social composition.

2. Fearer, Todd Matthew; Relationship of Ruffed Grouse Home Range Size and Movement to Landscape Characteristics in Southwestern Virginia: Gary Norman, Carola Haas, Roy L. Kirkpatrick, Dean F. Stauffer; (in English) I addressed the effects of landscape characteristics on ruffed grouse (Bonasa umbellus) home range size and movement, and examined grouse selection for specific landscape characteristics and cover types. Grouse home ranges and movement patterns derived from telemetry data gathered from fall 1996 through fall 1998 were overlaid onto a GIS database of Clinch Mtn. Wildlife Management Area, VA. This database was developed from GPS data and LANDSAT thematic mapping imagery (30 m pixel scale) and was composed of 22 cover types. Landscape metrics were calculated using FRAGSTATS/ARC, and multiple regression was used to relate changes in home range size and movement to these metrics. I used Wilcoxon signed-rank tests to compare the values of landscape metrics calculated for each home range to those calculated for the area encompassed by the home range plus a surrounding 300 m buffer. I used Wilcoxon rank-sum tests to compare the values of landscape metrics for the home ranges to the metrics calculated for 50 33 ha random plots. I used compositional analysis to test for preferential use of cover types. I developed 2 regression models (P < 0.01) relating changes in home range size to landscape characteristics, 1 model (P = 0.09) relating the distance between seasonal home range centers to landscape characteristics, and 1 model (P = 0.03) relating average daily movement to landscape characteristics. Grouse home range size increased as patch shape became more irregular and patch size and the number of different cover types per hectare increased, and decreased as the amount of high contrast edge in the landscape increased. The distance between seasonal home range centers increased as Shannon's diversity index and the average distance between patches of similar cover types increased, and decreased as the amount of high contrast edge increased. Average daily movement increased as the average distance between patches of the same cover type increased and as the percent cover of a full (~75%) rhododendron and/or laurel understory within a grouse's home range increased, and decreased as the amount of high contrast edge in a bird's home range increased. Ruffed grouse were selecting areas with high densities of smaller than average patches that were of uniform size and regular shape and contained higher than average amounts of high contrast edge. Areas containing a greater diversity of cover types than what was available in the study area also were preferred. Within these areas, clearcuts and mesic deciduous stands with a rhododendron/laurel understory were the most preferred cover types. Creating and maintaining a landscape with high densities of small patches that are of uniform size and regular (square) shape would provide the highest quality ruffed grouse habitat in this region. Several of these patches should be early successional cover to provide an abundance of high contrast edge. Rhododendron and/or laurel thickets also may be beneficial as supplemental winter cover, and mesic stands of mature hardwoods should be well interspersed with these cover types to provide supplemental food sources.

3. Martin, Jennifer Dotson; A Descriptive Analysis of Tobacco Use Policies Among Select Family Day Homes in Virginia: James A. Krouscas, Charles R. Baffi, Kerry J. Redican; (in English) A DESCRIPTIVE ANALYSIS OF TOBACCO USE POLICIES AMONG SELECT FAMILY DAY HOMES IN VIRGINIA by Jennifer Dotson Martin (ABSTRACT) Environmental tobacco smoke (ETS) has been well established as a danger to children. Exposure to secondhand smoke can cause coughing and wheezing, bronchitis, pneumonia, ear infections, asthma, and sudden infant death syndrome (SIDS). Childhood exposure to ETS may also increase the risk of developing leukemia and lymphoma in childhood (Mitchell, 1997) as well as developing lung cancer as an adult (Glantz, 1992). Despite the great strides recently made in the implementation of regulatory measures to safeguard children from ETS in public places like schools, there remains significant concern regarding children's exposure at home and in their out-of-home care facilities (Ashley and Ferrence, 1998, Jarvis, 2000). In 1996, the Centers for Disease Control and Prevention estimated that there were 336,749 Virginia youth exposed to ETS in the home (State Tobacco Control Highlights, 1999). The purpose of this study was to ascertain the number of family day home providers who allow smoking in their home and/or those that have some type of smoking policy. The sample consisted of 746 licensed, registered or locally approved family day home providers through the Department of Social Services. Of these childcare providers, 81.5% (n=608) completed a questionnaire about their tobacco use policy and its effects. An overwhelming majority (94.7%) of providers reported having a tobacco use policy in their family day home. Most of the providers, 67.6% indicated that smoking was allowed outdoors only while 26.3% noted that smoking was not allowed anywhere at any time, indoor or outdoor. Other policy specifics and background information are discussed in the study. The implications of these findings and recommendations for future training and educational programs for family day home providers are also reviewed. [Text] [View with Perseus links] (1.62)

1. ... , Homer, A. ... ; Phasecoherent Transport in PbTe Wide Parabolic Quantum Wells: Conductance fluctuations have been observed in macroscopic, quasi 3D PbTe wide quantum wells. A significant increase of the correlation field occurs in a temperature range from 40 mK to 1.2K. At the same time the fluctuation amplitude stays near e^2/h although the lateral sample size is two orders of magnitude larger than any typical length scale of diffusive electron transport. We interpret this behavior in terms of phasecoherent electrontransport, which takes advantage of a dramatic enhancement of the phasecoherence length of electrons in edgechannels and edge channel loops in the bulk region., Comment: postscript file including 2 figs, 4 pages, paper presented at the 8th Int.

2. ... , Homer, A. ... ; Non Local Transport in PbTe Wide Parabolic Quantum Wells: The results of non-local experiments in different contact configurations are discussed in terms of a non-local behaviour of the contact arms. It is shown that the observed reproducible fluctuations can be understood to result from fluctuations of a non-local bulk current in the contact arms. The fluctuations are explained by edge channel backscattering because of potential fluctuations in the bulk region., Comment: postscript file including 2 figs, 4 pages, Paper presented at 12th Int.

3. ... , Homer, A. ... ; Quenching of the Quantum Hall Effect in PbTe Wide Parabolic Quantum Wells: We show that for the case of a many valley host semiconductor an edge channel (EC) related non-local behaviour can persist also in the 3D-regime where the quantum Hall effect (QHE) is already quenched. We demonstrate that the QHE is replaced by conductance fluctuations due to EC backscattering in the contact arms, which leads to a fluctuating current redistribution between a dissipative bulk electron system and a less-dissipative EC-system. Both electron systems are located in different valleys of the band structure. The linear increase of Rxx with the magnetic field is explained by EC-backscattering in the Hall bar, Comment: postscript file including 2 figs, 4 pages, Paper presented at ICPS-XXIII, Berlin 1996 [Text] [View with Perseus links] (1.47)
