  11. Agricultural Census 2012: Publishing Mashable GIS Big Data Services

    Science.gov (United States)

    Mueller, R.

    2014-12-01

    The 2012 Agricultural Census was released by the US Department of Agriculture (USDA) on May 2nd 2014; published on a quinquennial basis covering all facets of American production agriculture. The Agricultural Census is a comprehensive source of uniform published agricultural data for every state and county in the US. This is the first Agricultural Census that is disseminated with web mapping services using REST APIs. USDA developed an open GIS mashable web portal that depicts over 250 maps on Crops and Plants, Economics, Farms, Livestock and Animals, and Operators. These mapping services written in JavaScript replace the traditional static maps published as the Ag Atlas. Web users can now visualize, interact, query, and download the Agricultural Census data in a means not previously discoverable. Stakeholders will now be able to leverage this data for activities such as community planning, agribusiness location suitability analytics, availability of loans/funds, service center locations and staffing, and farm programs and policies. Additional sites serving compatible mashable USDA Big Data web services are as follows: The Food Environment Atlas, The Atlas of Rural and Small-Town America, The Farm Program Atlas, SNAP Data System, CropScape, and VegScape. All portals use a similar data organization scheme of "Categories" and "Maps" providing interactive mashable web services for agricultural stakeholders to exploit.

  12. Comparison of the USGS 2001 NLCD to the 2002 USDA Census of Agriculture for the Upper Midwest United States

    Maxwell, S.K.; Wood, E.C.; Janus, A.

    2008-01-01

    The U.S. Geological Survey (USGS) 2001 National Land Cover Database (NLCD) was compared to the U.S. Department of Agriculture (USDA) 2002 Census of Agriculture. We compared areal estimates for cropland at the state and county level for 14 States in the Upper Midwest region of the United States. Absolute differences between the NLCD and Census cropland areal estimates at the state level ranged from 1.3% (Minnesota) to 37.0% (Wisconsin). The majority of counties (74.5%) had differences of less than 100 km2. 7.2% of the counties had differences of more than 200 km2. Regions where the largest areal differences occurred were in southern Illinois, North Dakota, South Dakota, and Wisconsin, and generally occurred in areas with the lowest proportions of cropland (i.e., dominated by forest or grassland). Before using the 2001 NLCD for agricultural applications, such as mapping of specific crop types, users should be aware of the potential for misclassification errors, especially where the proportion of cropland to other land cover types is fairly low.

  17. Agricultural production in the United States by county: a compilation of information from the 1974 census of agriculture for use in terrestrial food-chain transport and assessment models

    1982-01-01

    Terrestrial food-chain models that simulate the transport of environmentally released radionuclides incorporate parameters describing agricultural production and practice. Often a single set of default parameters, such as that listed in USNRC Regulatory Guide 1.109, is used in lieu of site-specific information. However, the geographical diversity of agricultural practice in the United States suggests the limitations of a single set of default parameters for assessment models. This report documents default parameters with a county-wide resolution based on analysis of the 1974 US Census of Agriculture for use in terrestrial food chain models. Data reported by county, together with state-based information from the US Department of Agriculture, Economic and Statistics Service, provided the basis for estimates of model input parameters. This report also describes these data bases, their limitations, and lists default parameters by county. Vegetable production is described for four categories: leafy vegetables; vegetables and fruits exposed to airborne material; vegetables, fruits, and nuts protected from airborne materials; and grains. Livestock feeds were analyzed in categories of hay, silage, pasture, and grains. Pasture consumption was estimated from cattle and sheep inventories, their feed requirements, and reported quantities of harvested forage. The results were compared with assumed yields of the pasture areas reported. In addition, non-vegetable food production estimates including milk, beef, pork, lamb, poultry, eggs, goat milk, and honey are described. The agricultural parameters and land use information - in all 47 items - are tabulated in four appendices for each of the 3067 counties of the US reported to the Census of Agriculture, excluding those in Hawaii and Alaska.

    1998-01-01

    "This paper reviews the changing way in which census geography has been treated with the increasing automation of census data processing. A four-stage model of modern census geography development is presented. In the context of this model, current practice is reviewed, and new opportunities for automated census geography design presented, culminating in a current prototype for the separation of purpose-designed data collection and output geographies. The narrative is presented primarily from a British perspective, but focuses on internationally relevant issues such as the implementation of census geography design, and the influence of census output geography on data analysis."

    A federal census of the 2010 population has been underway since January 2011. The objective is to provide important insights into the composition of the resident population, households and families in Switzerland and identify trends. The census methods have been modernised so that it covers only information that is not already contained in Federal, Cantonal and municipal registries of persons; the information will be gathered via questionnaires issued to approximately 3% of the population residing in Switzerland. In order to obtain representative information about the local population, the Canton of Geneva has requested that questionnaires be issued to international civil servants and members of their families aged 15 and over who live in the Canton. They will be invited to respond to the questionnaire on a strictly voluntary basis. If they choose not to respond to the questionnaire, they will not be contacted again. The Permanent Swiss Mission to the International Organizations in Geneva wishes in advance t...

  8. Developing Poultry Facility Type Information from USDA Agricultural Census Data for Use in Epidemiological and Economic Models

    Energy Technology Data Exchange (ETDEWEB)

    Melius, C

    2007-12-05

    The epidemiological and economic modeling of poultry diseases requires knowing the size, location, and operational type of each poultry type operation within the US. At the present time, the only national database of poultry operations that is available to the general public is the USDA's 2002 Agricultural Census data, published by the National Agricultural Statistics Service, herein referred to as the 'NASS data'. The NASS data provides census data at the county level on poultry operations for various operation types (i.e., layers, broilers, turkeys, ducks, geese). However, the number of farms and sizes of farms for the various types are not independent since some facilities have more than one type of operation. Furthermore, some data on the number of birds represents the number sold, which does not represent the number of birds present at any given time. In addition, any data tabulated by NASS that could identify numbers of birds or other data reported by an individual respondent is suppressed by NASS and coded with a 'D'. To be useful for epidemiological and economic modeling, the NASS data must be converted into a unique set of facility types (farms having similar operational characteristics). The unique set must not double count facilities or birds. At the same time, it must account for all the birds, including those for which the data has been suppressed. Therefore, several data processing steps are required to work back from the published NASS data to obtain a consistent database for individual poultry operations. This technical report documents data processing steps that were used to convert the NASS data into a national poultry facility database with twenty-six facility types (7 egg-laying, 6 broiler, 1 backyard, 3 turkey, and 9 others, representing ducks, geese, ostriches, emus, pigeons, pheasants, quail, game fowl breeders and 'other'). The process involves two major steps. The first step defines the rules used to

  10. Slovenia and the Census: From the 20. Century Yugoslav Counts to the Register-based Census of 2011

    Directory of Open Access Journals (Sweden)

    Damir Josipovič

    2015-12-01

    Full Text Available The article critically examines censuses in the Republic of Slovenia. Owing to its Yugoslav past, the censuses after 1945 have been closely scrutinized, and the common Yugoslav census methodology had a strong influence on the 1991 and 2002 censuses. The 1991 enumeration was carried out within the Yugoslav state; however the data processing and result publishing was done under the newly independent Slovenian state. The 2002 census was the last census to be carried out using classic door-to-door enumeration, since the 2011 census was completely register-based. The paper explores censuses in Slovenia since 1991, noting numerous changes and controversies. In 2002, in contrast to 1991, the applied definition of the resident population left out some 35,000 people working temporarily abroad. In addition, the 2002 census witnessed the highest ever number of ethnically non-affiliated respondents. An even bigger controversy was related to the erasure of some 30,000 people from the register of permanent residents for failing to apply for Slovenian citizenship after the break-up of Yugoslavia. The article also briefly reviews the difficulty in addressing the status of the constitutional national minorities and other unrecognized former Yugoslav nations in a situation in which specific data on their number, social and economic structure are no longer collected.

  15. Digit preference in Nigerian censuses data of 1991 and 2006

    Directory of Open Access Journals (Sweden)

    Tukur Dahiru

    2013-06-01

    Full Text Available Background: censuses in developing countries are prone to errors of age misreporting due to ignorance, low literacy levels and other social, economic and cultural factors. Ages are commonly rounded with great affinity for 0 or 5. This tendency to digit preference and/or avoidance results in age heaping or concentration of ages at certain digits. This study examined the extent of digit preference in the Nigerian census data of 1991 and 2006.Methods: this study utilized age data from the 1991 and 2006 Nigerian censuses reported in single years. The Whipple and Myers indices were used to determine the extent of digit preference.Results: both the 1991 and 2006 census data showed the expected pattern of errors, with Whipple and Myers indices being beyond acceptable levels. The Whipple index for 1991 and 2006 was 293 and 251 respectively, while the Myers index was 62.3 and 67.1 respectively. There was a strong preference for terminal digits 0 and 5, followed by 8 whereas terminal digits 1 and 9 were strongly avoided.Conclusions: the quality of age data in Nigerian census data is poor as a result of misreporting and no significant improvement or difference was observed between 1991 and 2006 censuses.

    2012-01-01

    The Census of Marine Life was a 10-year, international research effort to explore poorly known ocean habitats and conduct large-scale experimentation with new technology. The goal of Census 2010 in its mission statement was to describe what did live in the oceans, what does live in the oceans, and what will live in the ocean. Many of the findings and techniques from census research may prove valuable in making a transition, which many governments have publicly endorsed, from single-species fisheries management to more holistic ecosystem management. Census researchers sampled continental margins, mid-Atlantic ridges, ocean floor vents and seeps, and abyssal plains and polar seas and organized massive amounts of past and new information in a public online database called the Ocean Biogeographic Information System (www.iobis.org). The census described and categorized seamount biology worldwide for its vulnerability to fishing, advanced large-scale animal tracking with acoustic arrays and satellite archival tags, and accelerated species identification, including nearshore, coral reef, and zooplankton sampling using genetic barcoding and pyrotag sequencing for microbes and helped to launch the exciting new field of marine environmental history. Above all, the census showed the value of investing in large-scale, collaborative projects and sharing results publicly.

  18. Developing Livestock Facility Type Information from USDA Agricultural Census Data for Use in Epidemiological and Economic Models

    2006-10-24

    The epidemiological and economic modeling of livestock diseases requires knowing the size, location, and operational type of each livestock facility within the US. At the present time, the only national database of livestock facilities that is available to the general public is the USDA's 2002 Agricultural Census data, published by the National Agricultural Statistics Service, herein referred to as the 'NASS data.' The NASS data provides facility data at the county level for various livestock types (i.e., beef cows, milk cows, cattle on feed, other cattle, total hogs and pigs, sheep and lambs, milk goats, and angora goats). However, the number and sizes of facilities for the various livestock types are not independent since some facilities have more than one type of livestock, and some livestock are of more than one type (e.g., 'other cattle' that are being fed for slaughter are also 'cattle on feed'). In addition, any data tabulated by NASS that could identify numbers of animals or other data reported by an individual respondent is suppressed by NASS and coded with a 'D.'. To be useful for epidemiological and economic modeling, the NASS data must be converted into a unique set of facility types (farms having similar operational characteristics). The unique set must not double count facilities or animals. At the same time, it must account for all the animals, including those for which the data has been suppressed. Therefore, several data processing steps are required to work back from the published NASS data to obtain a consistent database for individual livestock operations. This technical report documents data processing steps that were used to convert the NASS data into a national livestock facility database with twenty-eight facility types. The process involves two major steps. The first step defines the rules used to estimate the data that is suppressed within the NASS database. The second step converts the NASS

  15. The generation of spatial population distributions from census centroid data

    OpenAIRE

    I Bracken; Martin, D.

    1989-01-01

    Census data are commonly used in geographical analysis and to inform planning purposes, though at the disaggregate level the basis of enumeration poses difficulties. In this paper an approach to surface generation is described that offers the prospect of revealing an underlying population distribution from centroid-based data which is independent of zonal geography. It is suggested that this can serve a wide variety of analytical, cartographic, and policy purposes, including the creation of s...

  17. Stereo matching based on census transformation of image gradients

    Science.gov (United States)

    Stentoumis, C.; Grammatikopoulos, L.; Kalisperakis, I.; Karras, G.; Petsa, E.

    2015-05-01

    Although multiple-view matching provides certain significant advantages regarding accuracy, occlusion handling and radiometric fidelity, stereo-matching remains indispensable for a variety of applications; these involve cases when image acquisition requires fixed geometry and limited number of images or speed. Such instances include robotics, autonomous navigation, reconstruction from a limited number of aerial/satellite images, industrial inspection and augmented reality through smart-phones. As a consequence, stereo-matching is a continuously evolving research field with growing variety of applicable scenarios. In this work a novel multi-purpose cost for stereo-matching is proposed, based on census transformation on image gradients and evaluated within a local matching scheme. It is demonstrated that when the census transformation is applied on gradients the invariance of the cost function to changes in illumination (non-linear) is significantly strengthened. The calculated cost values are aggregated through adaptive support regions, based both on cross-skeletons and basic rectangular windows. The matching algorithm is tuned for the parameters in each case. The described matching cost has been evaluated on the Middlebury stereo-vision 2006 datasets, which include changes in illumination and exposure. The tests verify that the census transformation on image gradients indeed results in a more robust cost function, regardless of aggregation strategy.

    2012-01-01

    N-Acyl-L-homoserine lactones (AHLs) are a major class of quorum-sensing signals used by Gram-negative bacteria to regulate gene expression in a population-dependent manner, thereby enabling group behavior. Enzymes capable of generating and catabolizing AHL signals are of significant interest for the study of microbial ecology and quorum-sensing pathways, for understanding the systems that bacteria have evolved to interact with small-molecule signals, and for their possible use in therapeutic and industrial applications. The recent structural and functional studies reviewed here provide a detailed insight into the chemistry and enzymology of bacterial communication. PMID:22099187

    2016-01-01

    We report the detection of 48 millisecond pulsars (MSPs) out of 75 observed thus far using the LOFAR in the frequency range 110-188 MHz. We have also detected three MSPs out of nine observed in the frequency range 38-77 MHz. This is the largest sample of MSPs ever observed at these low frequencies, and half of the detected MSPs were observed for the first time at frequencies below 200 MHz. We present the average pulse profiles of the detected MSPs, their effective pulse widths and flux densities, and compare these with higher observing frequencies. The LOFAR pulse profiles will be publicly available via the EPN Database of Pulsar Profiles. We also present average values of dispersion measures (DM) and discuss DM and profile variations. About 35% of the MSPs show strong narrow profiles, another 25% exhibit scattered profiles, and the rest are only weakly detected. A qualitative comparison of the LOFAR MSP profiles with those at higher radio frequencies shows constant separation between profile components. Simi...

    Raduški Nada

    2006-01-01

    Full Text Available This article presents the ethnic structure of the population of Vojvodina according to the 2002 census results. Also, there are analyzed the ethnodemographic changes in the period 1991-2002, caused by the following relevant factors: natural movement, migration and changed declaration on national affiliation. Ethnocentric migrations (voluntary and forced primarily influenced the change of ethnic structure of the Vojvodina, in the sense of creating a nationally more homogeneous region, having in mind the national structure of refugee-population. On the other hand, the emigration of some other nationalities which migrated to their mother countries due to political and economic reasons influenced the ethnic structure of the population, too. On the whole, the ethnic picture of Vojvodina is a complex one and undergoing changes continuously. Having in mind that Vojvodina is a multiethnic and multiconfessional region, the question of minorities and interethnic relations is undoubtedly of great significance for the stability and demographic development of this region.

  10. Using Random Forest to Improve the Downscaling of Global Livestock Census Data.

    Directory of Open Access Journals (Sweden)

    Gaëlle Nicolas

    Full Text Available Large scale, high-resolution global data on farm animal distributions are essential for spatially explicit assessments of the epidemiological, environmental and socio-economic impacts of the livestock sector. This has been the major motivation behind the development of the Gridded Livestock of the World (GLW database, which has been extensively used since its first publication in 2007. The database relies on a downscaling methodology whereby census counts of animals in sub-national administrative units are redistributed at the level of grid cells as a function of a series of spatial covariates. The recent upgrade of GLW1 to GLW2 involved automating the processing, improvement of input data, and downscaling at a spatial resolution of 1 km per cell (5 km per cell in the earlier version. The underlying statistical methodology, however, remained unchanged. In this paper, we evaluate new methods to downscale census data with a higher accuracy and increased processing efficiency. Two main factors were evaluated, based on sample census datasets of cattle in Africa and chickens in Asia. First, we implemented and evaluated Random Forest models (RF instead of stratified regressions. Second, we investigated whether models that predicted the number of animals per rural person (per capita could provide better downscaled estimates than the previous approach that predicted absolute densities (animals per km2. RF models consistently provided better predictions than the stratified regressions for both continents and species. The benefit of per capita over absolute density models varied according to the species and continent. In addition, different technical options were evaluated to reduce the processing time while maintaining their predictive power. Future GLW runs (GLW 3.0 will apply the new RF methodology with optimized modelling options. The potential benefit of per capita models will need to be further investigated with a better distinction between rural

  18. A census of nuclear cyanobacterial recruits in the plant kingdom.

    Directory of Open Access Journals (Sweden)

    Szabolcs Makai

    Full Text Available The plastids and mitochondria of the eukaryotic cell are of endosymbiotic origin. These events occurred ~2 billion years ago and produced significant changes in the genomes of the host and the endosymbiont. Previous studies demonstrated that the invasion of land affected plastids and mitochondria differently and that the paths of mitochondrial integration differed between animals and plants. Other studies examined the reasons why a set of proteins remained encoded in the organelles and were not transferred to the nuclear genome. However, our understanding of the functional relations of the transferred genes is insufficient. In this paper, we report a high-throughput phylogenetic analysis to identify genes of cyanobacterial origin for plants of different levels of complexity: Arabidopsis thaliana, Chlamydomonas reinhardtii, Physcomitrella patens, Populus trichocarpa, Selaginella moellendorffii, Sorghum bicolor, Oryza sativa, and Ostreococcus tauri. Thus, a census of cyanobacterial gene recruits and a study of their function are presented to better understand the functional aspects of plastid symbiogenesis. From algae to angiosperms, the GO terms demonstrated a gradual expansion over functionally related genes in the nuclear genome, beginning with genes related to thylakoids and photosynthesis, followed by genes involved in metabolism, and finally with regulation-related genes, primarily in angiosperms. The results demonstrate that DNA is supplied to the nuclear genome on a permanent basis with no regard to function, and only what is needed is kept, which thereby expands on the GO space along the related genes.

    2016-01-01

    Following the recent expiry of the United Nations' 2015 Millennium Development Goals (MDGs), new international development agenda covering 2030 water, sanitation and hygiene (WASH) targets have been proposed, which imply new demands on data sources for monitoring relevant progress. This study evaluates drinking-water and sanitation classification systems from national census questionnaire content, based upon the most recent international policy changes, to examine national population census's ability to capture drinking-water and sanitation availability, safety, accessibility, and sustainability. In total, 247 censuses from 83 low income and lower-middle income countries were assessed using a scoring system, intended to assess harmonised water supply and sanitation classification systems for each census relative to the typology needed to monitor the proposed post-2015 indicators of WASH targets. The results signal a lack of international harmonisation and standardisation in census categorisation systems, especially concerning safety, accessibility, and sustainability of services in current census content. This suggests further refinements and harmonisation of future census content may be necessary to reflect ambitions for post-2015 monitoring. PMID:26986472

  1. Canadian census of district energy owners and operators

    International Nuclear Information System (INIS)

    There is renewed interest in finding clean, innovative solutions to address energy infrastructure challenges, while also helping to create healthy, sustainable communities as a result of the rising cost of energy, deteriorating electrical infrastructure, increasing energy demands, growing greenhouse gas emissions, and inefficient burning of fossil fuels for electricity and thermal demand. District energy (DE) contributes to a reduction in greenhouse gas emissions, provides a secure supply of energy, promotes compact urban form in new developments, enhances energy efficiency, reduces peak demands for electricity, offers long-term and flexible solutions to fuel choice options and contributes to sustainable community construction and development practices. The last inventory of Canada's DE systems was completed in the 1990s. A national survey of plant operators and owners was developed in order to contribute to updating the inventory of DE systems across Canada. This report presented the findings and results of the survey in order to prepare a national profile of DE plants of varying size, scale, age, sector and fuel types. The report provided a definition of DE and presented the methodology as well as census results. In order to enhance access to information in the DE database, raw recorded data will need to be converted into common metrics for comparison, tracking and further evaluation. refs., tabs., figs

  2. Comprehensive Census and Analysis of Nearby Debris Disk Stars

    Cotten, Tara H.

    2016-01-01

    Debris disks are intimately linked to planetary system evolution since the rocky material surrounding the star is believed to originate in collisions between planetesimals, asteroids and comets. With the conclusion of all major space infrared missions and lack of future large-scale infrared excess survey missions, it is time to make a complete list of all debris disk systems and search for trends in the population. A thorough search of the literature for infrared excess stars has been combined with a large-scale survey for excess stars in the Tycho-2 catalog that makes use of all available infrared photometry. The result is a list of ~580 unique high fidelity debris disk stars. This project seeks a comprehensive analysis of debris disk stars not yet completed on this large scale. A summary of the creation of the high fidelity debris disk census and the multi-facility endeavor to obtain various stellar and disk parameters for each debris disk will be presented. I will offer an exploration into the relationships between host stars and their debris disks through properties such as metallicity, age, and rotation.

  3. A Stellar Census of the Tucana-Horologium Moving Group

    CERN Document Server

    2014-01-01

    We report the selection and spectroscopic confirmation of 129 new late-type (K3-M6) members of the Tuc-Hor moving group, a nearby (~40 pc), young (~40 Myr) population of comoving stars. We also report observations for 13/17 known Tuc-Hor members in this spectral type range, and that 62 additional candidates are likely to be unassociated field stars; the confirmation frequency for new candidates is therefore 129/191 = 67%. We have used RVs, Halpha emission, and Li6708 absorption to distinguish contaminants and bona fide members. Our expanded census of Tuc-Hor increases the known population by a factor of ~3 in total and by a factor of ~8 for members with SpT>K3, but even so, the K-M dwarf population of Tuc-Hor is still markedly incomplete. The spatial distribution of members appears to trace a 2D sheet, with a broad distribution in X and Y, but a very narrow distribution (+/-5 pc) in Z. The corresponding velocity distribution is very small, with a scatter of +/-1.1 km/s about the mean UVW velocity. We also sho...

As part of the data release, all of the spectra were cross-correlated with 48 template spectra of stars, galaxies and QSOs to determine the best match. We compared the blue spectra by eye to the templates assigned in SDSS DR8. 10,856 of the objects matched their assigned template, 170 could not be classified due to low signal-to-noise (S/N), and 1034 were given new classifications. We identify 7458 DA white dwarfs, 1145 DB white dwarfs, 273 rarer white dwarfs (including carbon, DZ, DQ, and magnetic), 294 subdwarf O stars, 648 subdwarf B stars, 679 blue horizontal branch stars, 1026 blue stragglers, 13 cataclysmic variables, 129 white dwarf - M dwarf binaries, 36 objects with spectra similar to DO white dwarfs, 179 QSOs, and 10 galaxies.

    In 2006, the U.S. celebrates the 100th birthday of the census tract. These geographic units, born out of concerns for urban well-being, were first proposed in 1906 to provide a “convenient and scientific city map system” for the City of New York. They were employed for the first time in the U.S. census in 1910 in eight cities, via a joint effort involving the U.S. Census Bureau and state and local health departments. Initially termed “sanitary areas” because of their relevance to planning for...

    We report the selection and spectroscopic confirmation of 129 new late-type (SpT = K3-M6) members of the Tucana-Horologium moving group, a nearby (d ∼ 40 pc), young (τ ∼ 40 Myr) population of comoving stars. We also report observations for 13 of the 17 known Tuc-Hor members in this spectral type range, and that 62 additional candidates are likely to be unassociated field stars; the confirmation frequency for new candidates is therefore 129/191 = 67%. We have used radial velocities, Hα emission, and Li{sub 6708} absorption to distinguish between contaminants and bona fide members. Our expanded census of Tuc-Hor increases the known population by a factor of ∼3 in total and by a factor of ∼8 for members with SpT ≥ K3, but even so, the K-M dwarf population of Tuc-Hor is still markedly incomplete. Our expanded census allows for a much more detailed study of Tuc-Hor than was previously feasible. The spatial distribution of members appears to trace a two-dimensional sheet, with a broad distribution in X and Y, but a very narrow distribution (±5 pc) in Z. The corresponding velocity distribution is very small, with a scatter of ±1.1 km s{sup –1} about the mean UVW velocity for stars spanning the entire 50 pc extent of Tuc-Hor. We also show that the isochronal age (τ ∼ 20-30 Myr) and the lithium depletion boundary age (τ ∼ 40 Myr) disagree, following the trend in other pre-main-sequence populations for isochrones to yield systematically younger ages. The Hα emission line strength follows a trend of increasing equivalent width with later spectral type, as is seen for young clusters. We find that moving group members have been depleted of measurable lithium for spectral types of K7.0-M4.5. None of our targets have significant infrared excesses in the WISE W3 band, yielding an upper limit on warm debris disks of F < 0.7%. Finally, our purely kinematic and color-magnitude selection procedure allows us to test the efficiency and completeness for activity

  11. A Census of marine life: unknowable or just unknown?

    Science.gov (United States)

    O'Dor, Ron; Decker, Cynthia J.

    2002-01-01

    As an introduction to the entire volume, this article outlines the relationships among the five elements of the Census of Marine Life (CoML) that create new knowledge: (1) The Ocean Biogeographic Information System (OBIS), a marine component of the Global Biodiversity Information Facility, links marine databases around the world to provide an Internet accessible, dynamic interface for comparing species-level, geo-referenced biodiversity data in relation to ocean habitats. The entire CoML field project data will be managed in and accessible through OBIS. (2) The History of Marine Animal Populations (HMAP) is a unique new synthesis of historical and biological research that will document marine biodiversity, globally, up to 500 years ago, before significant human impact, and store it in formats compatible with modern data in OBIS. (3) The Scientific Committee on Oceanic Research Working Group 118 monitors and recommends advanced marine technologies, ready to be routinely used in CoML field projects. (4) CoML Initial Field Projects develop and calibrate these technologies in selected regions to facilitate and accelerate global biodiversity research. As calibrated technologies and protocols are adopted in many regions, qualitative and quantitative biodiversity discoveries accumulate. (5) The Future of Marine Animal Populations (FMAP) program will insure that the data in OBIS are suitable for modeling and predicting changes in global biodiversity in response to fishing, pollution, and climate change challenges. It will make datasets available for hindcasting and forecasting analyses linked to physical ocean observations and assist in documenting the impacts of conservation efforts on sustainability.

    We present first results from a LOFAR census of non-recycled pulsars. The census includes almost all such pulsars known (194 sources) at declinations Dec > 8° and Galactic latitudes |Gb| > 3°, regardless of their expected flux densities and scattering times. Each pulsar was observed for ≥20 min in the contiguous frequency range of 110-188 MHz. Full-Stokes data were recorded. We present the dispersion measures, flux densities, and calibrated total intensity profiles for the 158 pulsars detected in the sample. The median uncertainty in census dispersion measures (1.5 × 10-3 pc cm-3) is ten times smaller, on average, than in the ATNF pulsar catalogue. We combined census flux densities with those in the literature and fitted the resulting broadband spectra with single or broken power-law functions. For 48 census pulsars such fits are being published for the first time. Typically, thechoice between single and broken power-laws, as well as the location of the spectral break, were highly influenced by the spectral coverage of the available flux density measurements. In particular, the inclusion of measurements below 100 MHz appears essential for investigating the low-frequency turnover in the spectra for most of the census pulsars. For several pulsars, we compared the spectral indices from different works and found the typical spread of values to be within 0.5-1.5, suggesting a prevailing underestimation of spectral index errors in the literature. The census observations yielded some unexpected individual source results, as we describe in the paper. Lastly, we will provide this unique sample of wide-band, low-frequency pulse profiles via the European Pulsar Network Database.

    2006-01-01

    The article explores the importance of agricultulture in line with development of society. It uses examples of high productivity achieved in grain and cotton crops in lnner Mongolia and Xinjiang areas to show that the fundamental objective of agricultural science is to maximize crops through the most effective use of soil, fertilizer and water in gaining the greatest benefit from power of the sun. Agricultural science should take up relevant theories and methodologies from other sciences, such as biological science, earth science and economics. The use of information technology will have great benefits for agricultural science. It hopes the scientific communities of China can make a significant contribution to solving the problems facing our rural areas, farmers and agriculture itself.

    2007-03-01

    Full Text Available After becoming self-standing state one of new needs of Croatia important for agricultural profession, farmers, policy makers and public needs was regionalization of agriculture. It is the analyse of state of agroecological conditions in agrosphere and based on results identification and territorial separation of agricultural regions as parts of agrosphere with similar conditions for plant and animal growing and similar farming systems. On this track within a special project we fi nished an inventory of agrosphere, result of which is Regionalisation of Croatian Agriculture presented in this paper. Following wise message of old Chinese proverb cited above, the starting approach is the MFCAL concept (Multifunctional Character of Agriculture and Land, which means that apart from very important and primary economic, agriculture and agricultural land (soil in human life play other roles (functions of similar importance; environmental, social, cultural and spatial, as well as the role of shaping the cultural landscape as a factor of rural development. As well, we respect the point of view prevailing in EU that all natural resources used in agriculture but at the fi rst place soil as a major one, need sustainable use and efficient protection. Using the data on Land resource potential based primarily on data of General Soil Map of Croatia (GSM in a scale of 1:50 000 and results of our research in the period 2000 – 2003, the agrosphere of Croatia is divided in three agricultural regions; Pannonian with four, Mountain with two and Adriatic with three subregions.

  3. Living alone in South and Southeast Asia: An analysis of census data

    Directory of Open Access Journals (Sweden)

    Chai Podhisita

    2015-06-01

    Full Text Available Background: Living alone (in a one-person household has reached very high levels in some parts of the world. Across Asia the phenomenon is common in parts of East Asia, but has rarely been examined in South or Southeast Asia. Objective: The authors seek to establish from the evidence of censuses the main contours of living alone in South and Southeast Asia, and in doing so address issues of definition and measurement, particularly issues arising due to differences in the census handling of the 'group quarters' type of household. Methods: The paper examines 10 national censuses in the IPUMS archive of census micro-files. The data are explored for age profiles of living alone by sex, classified by urban versus rural residence and marital status. Results: The censuses reveal a combination of underlying commonalities among the countries and dates as well as distinct national features. There are distinct age profiles for males and females, and profiles typical of urban and rural sectors across countries. Living alone in group quarters is most common among young adults. Tabulation by marital status shows considerable variation among single young adults and elderly widowed or divorced/separated persons. It is also found that the proportions of the population not living with core family who are living alone vary widely by age and sex and across countries and years. Conclusions: Studies of living alone with national censuses must take note of whether conventional households and group quarters are included and how these are defined. Group quarters residence makes up a significant proportion of living alone among the young.

  4. The use of census migration data to approximate human movement patterns across temporal scales.

    Directory of Open Access Journals (Sweden)

    Amy Wesolowski

    Full Text Available Human movement plays a key role in economies and development, the delivery of services, and the spread of infectious diseases. However, it remains poorly quantified partly because reliable data are often lacking, particularly for low-income countries. The most widely available are migration data from human population censuses, which provide valuable information on relatively long timescale relocations across countries, but do not capture the shorter-scale patterns, trips less than a year, that make up the bulk of human movement. Census-derived migration data may provide valuable proxies for shorter-term movements however, as substantial migration between regions can be indicative of well connected places exhibiting high levels of movement at finer time scales, but this has never been examined in detail. Here, an extensive mobile phone usage data set for Kenya was processed to extract movements between counties in 2009 on weekly, monthly, and annual time scales and compared to data on change in residence from the national census conducted during the same time period. We find that the relative ordering across Kenyan counties for incoming, outgoing and between-county movements shows strong correlations. Moreover, the distributions of trip durations from both sources of data are similar, and a spatial interaction model fit to the data reveals the relationships of different parameters over a range of movement time scales. Significant relationships between census migration data and fine temporal scale movement patterns exist, and results suggest that census data can be used to approximate certain features of movement patterns across multiple temporal scales, extending the utility of census-derived migration data.

    2009-01-01

    Full Text Available Problem statement: Considering unsustainable agricultural conditions of Iran and organizational recession and inability of current extension organization to achieve sustainability, it seems that extension systems require a new organizational structure to achieve sustainability objectives. The purpose of the present study was to identify the most appropriate characteristics for extension organization toward green agriculture in Iran context. Approach: To fulfill this objective, a sample of 120 respondents was selected through simple random sampling technique. A survey study was applied as a methodology of research. A mailed questionnaire was used to collect the data. The response rate of questionnaire was 65.83% (N = 79. Appropriate descriptive statistics such as mean scores, standard deviations and variation ratio were used. Results: Extension experts believed that among important organizational characteristics of extension system for supporting green agriculture collaboration among research, extension, education organizations, farmers' associations, NGOs, rural credit agencies, transportation companies, considering local groups and learning organization had very high importance for supporting green agriculture. According to factor analysis, the implications for extension organization were categorized into two groups consisting: (1 Holistic organizations (2 Participatory organizations that those factors explained 67.54% of the total variance of the research variables. Conclusion: Identifying suitable extension mechanisms had important role for developing extension system. Therefore, identifying extension organizational characteristics for supporting green agriculture of Iran is one of the major approaches needs to be carefully thought and accurately implemented for the extension system development.

    Presser, H B

    1998-01-01

    "In 1970, as in previous decades, the U.S. Bureau of the Census's household enumeration began with a lead question as to who was the ¿head of household'. With the resurgence of feminism, this concept was challenged as an ambiguous concept which implied an authority structure imputed by the Bureau but not measured, and offensive to many people. This paper tells the story of successful feminist mobilization in the 1970s that led to the removal of this concept from the U.S. decennial censuses beginning with 1980." PMID:12294932

  9. MODERNIZATION OF AGRICULTURE VS SUSTAINABLE AGRICULTURE

    Directory of Open Access Journals (Sweden)

    Dariusz KUSZ

    2014-04-01

    Full Text Available The paper shows the correlation between the need to modernise agriculture and sustainable development. Modernisation of agriculture aiming only at increasing the efficiency of production, if implemented in accordance with the principles of sustainable development, enabled reduction in the negative external effects. Modernisation of agriculture is supposed to ensure productivity growth without imposing any threats to the natural environment and the well-being of animals, reduced impoverishment in rural areas as well as to ensure food security, growth in the profitability of farms, improvement to the efficiency of use of natural resources. Therefore, in the near future, the agriculture – environment relation will be subject to change taking into account, on the one hand, concern about the natural environment, and, on the other, pressure on increasing the efficiency of production. The above challenges will be addressed by the need to implement efficient and, at the same time, environmentally-friendly production technologies and relevant legal instruments which oblige agricultural producers to protect the natural environment.

    Census and disposal data provide a multipurpose source of information on cattle mortality. The retrospective analyses we conducted on the data gathered in the National Cattle Register produced relevant information for describing and modelling the cattle mortality baseline and evaluating the impact of the 2007-2008 Blue Tongue epidemic on the French cattle population. This work was conducted retrospectively but showed that monitoring cattle mortality near real time could help detecting unexpected events. We are thus currently working on a timely and automated system to monitor cadaver disposal requests received by rendering plants, thanks to a data interchange system recently implemented between the Ministry of Agriculture and the fallen stock companies. Besides technical and methodological challenges, using these data for surveillance purposes raises epidemiological questions that still need to be answered. The question remains notably as to whether an abnormal increased mortality is a sensitive and timely signal for detecting unexpected health events. It appears also very challenging to identify the most adequate surveillance scale (time, space and population) and the most adequate anomaly detection algorithms to apply when the characteristics of the signals to be detected (shape, amplitude, etc.) are not known a priori. In Human health, similar systems have not yet proven their ability to detect unexpected events earlier than classical surveillance systems currently in place, but they have already demonstrated their value for real time assessment of identified and potentially dangerous events. Combined with traditional surveillance systems, we think that monitoring routinely collected data could improve the surveillance of the animal population health. Even if not used for detection purposes, cattle mortality monitoring could be used to rapidly produce information on the impact and evolution of identified events, what would facilitate decision-making regarding

  19. Conclusion: The Politics of Numbers – Censuses in the Post-Yugoslav States

    Directory of Open Access Journals (Sweden)

    Soeren Keil

    2015-12-01

    Full Text Available This conclusion poses a number of questions related to policy issues and the censuses in the post-Yugoslav states. It is argued that censuses are always more than just a technical counting exercise. Census discussions in Western Europe tend to focus on regional funding, infrastructure support and long-term policy planning, and can be as contested and heated as questions over identity, religion and mother tongue in the post-Yugoslav states. However, identity-related questions in an area in which identity is still in flux and in which fundamental demographic changes have taken place recently, prevent any focus on more policy-oriented discussions. In their EU integration process, all of the post-Yugoslav countries will have to concentrate on issues such as economic development, sustainable infrastructure planning, budgeting within the strict rules of the most recent EU agreements and hence policy discussions should be at the forefront of the debates about the results of the censuses. Instead, discussions over who is counted and how remain of key importance in all countries (even those that have joined the EU, and demonstrate unconsolidated nation-building projects.

    The main objective of this paper is to review and discuss the applicability of statistical procedures for the detection of density dependence based on a series of annual or multi-annual censuses. Regression models for which the statistic value under the null hypothesis of density independence is set a priori (slope = 0 or 1), generate spurious indications of density dependence. These tests are inappropriate because low sample sizes, high variance, and sampling error consistently bias the slop...

  16. The census of complex organic molecules in the solar type protostar IRAS16293-2422

    CERN Document Server

    Jaber, Ali A; Kahane, C; Caux, E

    2014-01-01

    Complex Organic Molecules (COMs) are considered crucial molecules, since they are connected with organic chemistry, at the basis of the terrestrial life. More pragmatically, they are molecules in principle difficult to synthetize in the harsh interstellar environments and, therefore, a crucial test for astrochemical models. Current models assume that several COMs are synthesised on the lukewarm grain surfaces ($\\gtrsim$30-40 K), and released in the gas phase at dust temperatures $\\gtrsim$100 K. However, recent detections of COMs in $\\lesssim$20 K gas demonstrate that we still need important pieces to complete the puzzle of the COMs formation. We present here a complete census of the oxygen and nitrogen bearing COMs, previously detected in different ISM regions, towards the solar type protostar IRAS16293-2422. The census was obtained from the millimeter-submillimeter unbiased spectral survey TIMASSS. Six COMs, out of the 29 searched for, were detected: methyl cyanide, ketene, acetaldehyde, formamide, dimethyl ...

    The abundance of compact and massive early-type galaxies (ETGs) can provide significant constraints on the galaxy merging history. The optical Kilo Degree Survey (KiDS), carried out with the VST, gives a unique opportunity to perform a complete census of the most compact galaxies in the Universe.

  18. The Census, Maps, and Museums, or a Way of ‘Translating’ Identity

    Directory of Open Access Journals (Sweden)

    Mihály Vilma-Irén

    2014-12-01

    Full Text Available The Census, which aims at recording pieces of information about the members of the population of a country, the historical and geographical maps drawn at the orders of the government, as well as national museums, may be more than the mere sum of the collected data to be presented. Based upon Benedict Anderson’s theory, as shown in his book entitled Imagined Communities: Reflections on the Origin and Spread of Nationalism (2006, in my paper I shall try to point at the subtle ways in which official governmental institutions have tried to use the Census, maps and museums in order to shape national identity and influence the image of a nation. Quite often what one can read about the results of the Census, what one can see on a map or encounter in a museum are not objective facts, but items placed there carefully, fulfilling specific purposes. On the one hand, they target the compatriots, on the other hand, the foreigners. Could we say that what we are dealing with here is not only an act of cultural mediation, but also a specific way of ‘translating’ identity? The next couple of pages shall try to analyze the topic and find an answer to the question above by giving examples.

  1. Inferring a district-based hierarchical structure of social contacts from census data.

    Directory of Open Access Journals (Sweden)

    Z Yu

    Full Text Available Researchers have recently paid attention to social contact patterns among individuals due to their useful applications in such areas as epidemic evaluation and control, public health decisions, chronic disease research and social network research. Although some studies have estimated social contact patterns from social networks and surveys, few have considered how to infer the hierarchical structure of social contacts directly from census data. In this paper, we focus on inferring an individual's social contact patterns from detailed census data, and generate various types of social contact patterns such as hierarchical-district-structure-based, cross-district and age-district-based patterns. We evaluate newly generated contact patterns derived from detailed 2011 Hong Kong census data by incorporating them into a model and simulation of the 2009 Hong Kong H1N1 epidemic. We then compare the newly generated social contact patterns with the mixing patterns that are often used in the literature, and draw the following conclusions. First, the generation of social contact patterns based on a hierarchical district structure allows for simulations at different district levels. Second, the newly generated social contact patterns reflect individuals social contacts. Third, the newly generated social contact patterns improve the accuracy of the SEIR-based epidemic model.

  3. Agriculture

    International Nuclear Information System (INIS)

    The report entitled Climate Change Impacts and Adaptation : A Canadian Perspective, presents a summary of research regarding the impacts of climate change on key sectors over the past five years as it relates to Canada. This chapter on agriculture describes how climate change will affect primary agriculture production in Canada with particular focus on potential adaptation options, and vulnerability of agriculture at the farm level. Agriculture is a vital part of the Canadian economy, although only 7 per cent of Canada's land mass is used for agricultural purposes due to the limitations of climate and soils. Most parts of Canada are expected to experience warmer conditions, longer frost-free seasons and increased evapotranspiration. The impacts of these changes on agriculture will vary depending on precipitation changes, soil conditions, and land use. Northern regions may benefit from longer farming seasons, but poor soil conditions will limit the northward expansion of agricultural crops. Some of the negative impacts associated with climate change on agriculture include increased droughts, changes in pest and pathogen outbreaks, and moisture stress. In general, it is expected that the positive and negative impacts of climate change would offset each other. 74 refs., 2 tabs., 1 fig

  12. A Comprehensive Census of Nearby Infrared Excess Stars

    Cotten, Tara H.; Song, Inseok

    2016-07-01

    The conclusion of the Wide-Field Infrared Survey Explorer (WISE) mission presents an opportune time to summarize the history of using excess emission in the infrared as a tracer of circumstellar material and exploit all available data for future missions such as the James Webb Space Telescope. We have compiled a catalog of infrared excess stars from peer-reviewed articles and perform an extensive search for new infrared excess stars by cross-correlating the Tycho-2 and all-sky WISE (AllWISE) catalogs. We define a significance of excess in four spectral type divisions and select stars showing greater than either 3σ or 5σ significance of excess in the mid- and far-infrared. Through procedures including spectral energy distribution fitting and various image analyses, each potential excess source was rigorously vetted to eliminate false positives. The infrared excess stars from the literature and the new stars found through the Tycho-2 and AllWISE cross-correlation produced nearly 500 “Prime” infrared excess stars, of which 74 are new sources of excess, and >1200 are “Reserved” stars, of which 950 are new sources of excess. The main catalog of infrared excess stars are nearby, bright, and either demonstrate excess in more than one passband or have infrared spectroscopy confirming the infrared excess. This study identifies stars that display a spectral energy distribution suggestive of a secondary or post-protoplanetary generation of dust, and they are ideal targets for future optical and infrared imaging observations. The final catalogs of stars summarize the past work using infrared excess to detect dust disks, and with the most extensive compilation of infrared excess stars (∼1750) to date, we investigate various relationships among stellar and disk parameters.

    The Square Kilometre Array (SKA) will make ground breaking discoveries in pulsar science. In this chapter we outline the SKA surveys for new pulsars, as well as how we will perform the necessary follow-up timing observations. The SKA's wide field-of-view, high sensitivity, multi-beaming and sub-arraying capabilities, coupled with advanced pulsar search backends, will result in the discovery of a large population of pulsars. These will enable the SKA's pulsar science goals (tests of General Relativity with pulsar binary systems, investigating black hole theorems with pulsar-black hole binaries, and direct detection of gravitational waves in a pulsar timing array). Using SKA1-MID and SKA1-LOW we will survey the Milky Way to unprecedented depth, increasing the number of known pulsars by more than an order of magnitude. SKA2 will potentially find all the Galactic radio-emitting pulsars in the SKA sky which are beamed in our direction. This will give a clear picture of the birth properties of pulsars and of the gr...

  14. A SPECTROSCOPIC CENSUS OF THE M82 STELLAR CLUSTER POPULATION

    International Nuclear Information System (INIS)

    We present a spectroscopic study of the stellar cluster population of M82, the archetype starburst galaxy, based primarily on new Gemini-North multi-object spectroscopy of 49 star clusters. These observations constitute the largest to date spectroscopic data set of extragalactic young clusters, giving virtually continuous coverage across the galaxy; we use these data to deduce information about the clusters as well as the M82 post-starburst disk and nuclear starburst environments. Spectroscopic age dating places clusters in the nucleus and disk between (7, 15) and (30, 270) Myr, with distribution peaks at ∼10 and 140 Myr, respectively. We find cluster radial velocities (RVs) in the range vR in (-160, 220)km s-1 (with respect to the galaxy center), and line-of-sight Na I D interstellar absorption line velocities v NaIDR in (-75, 200) km s-1, in many cases entirely decoupled from the clusters. As the disk cluster RVs lie on the flat part of the galaxy rotation curve, we conclude that they comprise a regularly orbiting system. Our observations suggest that the largest part of the population was created as a result of the close encounter with M81 ∼220 Myr ago. Clusters in the nucleus are found in solid body rotation on the bar. The possible detection of Wolf-Rayet features in their spectra indicates that cluster formation continues in the central starburst zone. We also report the potential discovery of two old populous clusters in the halo of M82, aged ∼>8 Gyr. Using these measurements and simple dynamical considerations, we derive a toy model for the invisible physical structure of the galaxy, and confirm the existence of two dominant spiral arms.

    The costs of photovoltaic (PV) system hardware (PV panels, inverters, racking, etc.) have fallen dramatically over the past few years. Nonhardware (soft) costs, however, have failed to keep pace with the decrease in hardware costs, and soft costs have become a major driver of U.S. PV system prices. Upfront or 'sunken' customer acquisition costs make up a portion of an installation's soft costs and can be addressed through software solutions that aim to streamline sales and system design aspects of customer acquisition. One of the key soft costs associated with sales and system design is collecting information on solar access for a particular site. Solar access, reported in solar access values (SAVs), is a measurement of the available clear sky over a site and is used to characterize the impacts of local shading objects. Historically, onsite shading studies have been required to characterize the SAV of the proposed array and determine the potential energy production of a photovoltaic system.

    2009-01-01

    At ~ 400 pc, the Horsehead Nebula (B33) is the closest radiatively-sculpted pillar to the Sun, but the state and extent of star formation in this structure is not well understood. We present deep near-infrared (IRSF/SIRIUS JHKs) and mid-infrared (Spitzer/IRAC) observations of the Horsehead Nebula in order to characterize the star forming properties of this region and to assess the likelihood of triggered star formation. Infrared color-color and color-magnitude diagrams are used to identify young stars based on infrared excess emission and positions to the right of the Zero-Age Main Sequence, respectively. Of the 45 sources detected at both near- and mid-infrared wavelengths, three bona fide and five candidate young stars are identified in this 7' by 7' region. Two bona fide young stars have flat infrared SEDs and are located at the western irradiated tip of the pillar. The spatial coincidence of the protostars at the leading edge of this elephant trunk is consistent with the Radiation-Driven Implosion (RDI) m...

  19. A Radio Census of Binary Supermassive Black Holes

    CERN Document Server

    Burke-Spolaor, Sarah

    2010-01-01

    Using archival VLBI data for 3114 radio-luminous active galactic nuclei, we searched for binary supermassive black holes using a radio spectral index mapping technique which targets spatially resolved, double radio-emitting nuclei. Only one source was detected as a double nucleus. This result is compared with a cosmological merger rate model and interpreted in terms of (1) implications for post-merger timescales for centralisation of the two black holes, (2) implications for the possibility of "stalled" systems, and (3) the relationship of radio activity in nuclei to mergers. Our analysis suggests that the binary evolution of paired supermassive black holes (both of masses >= 1e8 Msun) spends less than 500 Myr in progression from the merging of galactic stellar cores to within the purported stalling radius for supermassive black hole pairs. The data show no evidence for an excess of stalled binary systems at small separations. We see circumstantial evidence that the relative state of radio emission between pa...

    2007-01-01

    The first paper in this series took a direct census of energy input from the known OB stars in the Carina Nebula, and in this paper we study the global properties of the surrounding nebulosity. We find that the total IR luminosity of Carina is about 1.2E7 Lsun, accounting for only about 50-60% of the known stellar luminosity from Paper I. Similarly, the ionizing photon luminosity -- (abridged; many important details omitted). Synchronized star formation around the periphery of Carina provides...

  1. Comprehensive Census and Complete Characterization of Nearby Debris Disk Stars

    Debris disks are intimately linked to planetary system evolution since the rocky material surrounding the host stars is believed to be due to secondary generation from the collisions of planetesimals. With the conclusion and lack of future large scale infrared excess survey missions, it is time to summarize the history of using excess emission in the infrared as a tracer of debris and exploit all available data as well as provide a comprehensive study of the parameters of these important objects. We have compiled a catalog of infrared excess stars from peer-reviewed articles and performed an extensive search for new debris disks by cross-correlating the Tycho-2 and AllWISE catalogs. This study will conclude following the thorough examination of each debris disk star's parameters obtained through high-resolution spectroscopy at various facilities which is currently ongoing. We will maintain a webpage (www.debrisdisks.org) devoted to these infrared excess sources and provide various resources related to our catalog creation, SED fitting, and data reduction.

  3. A Census of Baryons in Galaxy Clusters and Groups

    Gonzalez, Anthony H.; Zaritsky, Dennis; Zabludoff, Ann I.

    2007-09-01

    We determine the contribution of stars in galaxies, intracluster stars, and the intracluster medium to the total baryon budget in nearby galaxy clusters and groups. We find that the baryon mass fraction (fb≡Ωb/Ωm) within r500 is constant for systems with M500 between 6×1013 and 1×1015 Msolar. Although fb is lower than the WMAP value, the shortfall is on the order of both the observational systematic uncertainties and the depletion of baryons within r500 that is predicted by simulations. The data therefore provide no compelling evidence for undetected baryonic components, particularly any that would be expected to vary in importance with cluster mass. A unique feature of the current analysis is direct inclusion of the contribution of intracluster light (ICL) in the baryon budget. With the addition of the ICL to the stellar mass in galaxies, the increase in X-ray gas mass fraction with increasing total mass is entirely accounted for by a decrease in the total stellar mass fraction, supporting the argument that the behavior of both the stellar and X-ray gas components is dominated by a decrease in star formation efficiency in more massive environments. Within just the stellar component, the fraction of the total stellar luminosity in the central, giant brightest cluster galaxy (BCG) and ICL (hereafter the BCG+ICL component) decreases as velocity dispersion (σ) increases for systems with 145 km s-1behavior arises from our sample selection, which favored systems with central, giant elliptical galaxies, remains unclear. A more robust result is the identification of low-mass groups with large BCG+ICL components, demonstrating that the creation of ``intracluster'' stars does not require a massive cluster environment. Within r500 and r200, the BCG+ICL contributes on average 40% and 33% of the total stellar light, respectively, for the clusters and groups in our sample. Because these fractions are functions of both enclosed radius and system mass, care should be

    The conclusion of the WISE mission presents an opportune time to summarize the history of using excess emission in the infrared as a tracer of circumstellar material and exploit all available data for future missions such as JWST. We have compiled a catalog of infrared excess stars from peer-reviewed articles and perform an extensive search for new infrared excess stars by cross-correlating the Tycho-2 and AllWISE catalogs. We define a significance of excess in four spectral type divisions and select stars showing greater than either 3$\\sigma$ or 5$\\sigma$ significance of excess in the mid- and far-infrared. Through procedures including SED fitting and various image analyses, each potential excess source was rigorously vetted to eliminate false-positives. The infrared excess stars from the literature and the new stars found through the Tycho-2 and AllWISE cross-correlation produced nearly 500 `Prime' infrared excess stars and $\\geq$1200 `Reserved' stars. The main catalog of infrared excess stars are nearby, b...

    We report new spectral types or spectral classification constraints for over 600 stars in the Orion Nebula Cluster (ONC) based on medium resolution (R ≈ 1500-2000) red optical spectra acquired using the Palomar 200'' and Kitt Peak 3.5 m telescopes. Spectral types were initially estimated for F, G, and early K stars from atomic line indices while for late K and M stars, which constitute the majority of our sample, indices involving TiO and VO bands were used. To ensure proper classification, particularly for reddened, veiled, or nebula-contaminated stars, all spectra were then visually examined for type verification or refinement. We provide an updated spectral type table that supersedes previous work, increasing the percentage of optically visible ONC stars with spectral type information from 68% to 90%. However, for many objects, repeated observations have failed to yield spectral types primarily due to the challenges of adequate sky subtraction against a bright and spatially variable nebular background. The scatter between our new and our previously determined spectral types is approximately two spectral sub-classes. We also compare our grating spectroscopy results with classification based on narrow-band TiO filter photometry, finding similar scatter. While the challenges of working in the ONC may explain much of the spread, we highlight several stars showing significant and unexplained bona fide spectral variations in observations taken several years apart; these and similar cases could be due to a combination of accretion and extinction changes. Finally, nearly 20% of ONC stars exhibit obvious Ca II triplet emission indicative of strong accretion.

    With the Wide-Field Infrared Survey Explorer (WISE), we searched for young stellar objects (YSOs) in a 100 deg^2 region centered on the lightly studied Canis Major star forming region. Applying stringent magnitude cuts to exclude the majority of extragalactic contaminants, we find 144 Class I candidates and 335 Class II candidates. The sensitivity to Class II candidates is limited by their faintness at the distance to Canis Major (assumed as 1000 pc). More than half the candidates (53%) are f...

Applying stringent magnitude cuts to exclude the majority of extragalactic contaminants, we find 144 Class I candidates and 335 Class II candidates. The sensitivity to Class II candidates is limited by their faintness at the distance to Canis Major (assumed as 1000 pc). More than half the candidates (53%) are found in 16 groups of more than four members, including four groups with more than 25 members each. The ratio of Class II to Class I objects, N_II/N_I, varies from 0.4 to 8.3 in just the largest four groups. We compare our results to those obtainable with combined Two Micron All Sky Survey (2MASS) and post-cryogenic Spitzer Space Telescope data; the latter approach recovers missing Class II sources. Via a comparison to protostars characterized with the Herschel Space Observatory, we propose new WISE color criteria for flat...

  9. A census of transient orbital resonances encountered during binary inspiral

    CERN Document Server

    Ruangsri, Uchupol

    2013-01-01

    Transient orbital resonances have recently been identified as potentially important to the inspiral of small bodies into large black holes. These resonances occur as the inspiral evolves through moments in which two fundamental orbital frequencies, $\\Omega_\\theta$ and $\\Omega_r$, are in a small integer ratio to one another. Previous work has demonstrated that a binary's parameters are "kicked" each time the inspiral passes through a resonance, changing the orbit's characteristics relative to a model that neglects resonant effects. In this paper, we use exact Kerr geodesics coupled to an accurate but approximate model of inspiral to survey orbital parameter space and estimate how commonly one encounters long-lived orbital resonances. We find that the most important resonances last for a few hundred orbital cycles at mass ratio $10^{-6}$, and that resonances are almost certain to occur during the time that a large mass ratio binary would be a target of gravitational-wave observations. Resonances appear to be ub...

    2011-06-01

    An opinion piece published in Nature proposed a global network for agricultural monitoring [J. Sachs, R. Remans, S. Smukler, L. Winowiecki, S. J. Andelman, K. G. Cassman, D. Castle, R. DeFries, G. Denning, J. Fanzo, L. E. Jackson, R. Leemans, J. Leemans, J. C. Milder, S. Naeem, G. Nziguheba, C. A. Palm, J. P. Reganold, D. D. Richter, S. J. Scherr, J. Sircely, C. Sullivan, T. P. Tomich and P. A. Sanchez, Nature, 2010, 466, 558-560.]. Whilst we agree with Sachs et al. that monitoring of agricultural systems is a critically important activity of global significance, especially given increasing problems with global food security and the potential impacts of agriculture on the environment [J. Cribb, The Coming Famine. The Global Food Crisis and What We Can Do to Avoid It, CSIRO Publishing and University of California Press, Melbourne and Oakland, 2010.], we argue in this paper that their generic, mandated monitoring framework has a high probability of failure or at best will be highly inefficient. We base this conclusion on our recently published examination of the factors influencing the success or failure of monitoring programs worldwide [D. B. Lindenmayer and G. E. Likens, Effective Ecological Monitoring, CSIRO Publishing and Earthscan, Melbourne and London, 2010.]. We briefly outline what we believe are three serious flaws in the monitoring framework proposed by Sachs et al. We then suggest an alternative approach that we argue would be more effective, more efficient, and have a greater chance of successfully addressing key issues in sustainable agriculture.

  12. The Analysis of Migration Processes in Russia According to the Census

    Directory of Open Access Journals (Sweden)

    Olga Dmitrievna Vorobieva

    2016-03-01

    Full Text Available The subject matter of the study is the internal migration of the Russian population from 1960 to 2010. The study is based on the information about the spatial population movements, published in the proceedings of the all-Union censuses of 1970, 1979, 1989, and of the all-Russian censuses of 2002 and 2010. The main flows and directions of migration are considered. The methodological analysis of the migration was performed by means of cross-cutting indicators to assess the dynamics of migration processes over a long period. Special attention is given to the rural-urban internal migration, as its volumes, patterns and impacts have not been adequately tested and evaluated to date. Relative indicators, which have not been used previously to assess the studied processes are proposed and calculated. To ensure the comparability of the materials of the censuses of the Soviet and post-Soviet periods under consideration, the economic zoning adopted prior to 2000 was used, and the uniformity of administrative scale was ensured. The hypothesis that from decade to decade, there was a decrease of the intensity of territorial mobility for both urban and rural populations is confirmed. The inter-regional migration flows are considered; the different trends and intensity of migration processes for more than four decades are specified. The dynamics of the structure of migrants on the basis of length of residence in the place of permanent residence in different regions is analyzed. The study has shown that the development and preservation of the prevailing trends in that period continues to adversely affect the territorial distribution of the population and the regional socio-economic development of the country. The findings can find their application in the correction of regional socio-economic and migration policies.

    The compaction of field soils due to repeated rolling of agricultural vehicles is one of the main reasons for the agricultural soil degradation. A good understanding of the compaction properties of these soils is essential for an optimum organisation of agricultural activities, and therefore for environmental protection in terms of nitrate migrations. In the present work, the compaction properties of agricultural soils from four sites in France are studied after experimental data ...

  15. phyloseq: an R package for reproducible interactive analysis and graphics of microbiome census data.

    Directory of Open Access Journals (Sweden)

    Paul J McMurdie

    Full Text Available the analysis of microbial communities through dna sequencing brings many challenges: the integration of different types of data with methods from ecology, genetics, phylogenetics, multivariate statistics, visualization and testing. With the increased breadth of experimental designs now being pursued, project-specific statistical analyses are often needed, and these analyses are often difficult (or impossible for peer researchers to independently reproduce. The vast majority of the requisite tools for performing these analyses reproducibly are already implemented in R and its extensions (packages, but with limited support for high throughput microbiome census data.Here we describe a software project, phyloseq, dedicated to the object-oriented representation and analysis of microbiome census data in R. It supports importing data from a variety of common formats, as well as many analysis techniques. These include calibration, filtering, subsetting, agglomeration, multi-table comparisons, diversity analysis, parallelized Fast UniFrac, ordination methods, and production of publication-quality graphics; all in a manner that is easy to document, share, and modify. We show how to apply functions from other R packages to phyloseq-represented data, illustrating the availability of a large number of open source analysis techniques. We discuss the use of phyloseq with tools for reproducible research, a practice common in other fields but still rare in the analysis of highly parallel microbiome census data. We have made available all of the materials necessary to completely reproduce the analysis and figures included in this article, an example of best practices for reproducible research.The phyloseq project for R is a new open-source software package, freely available on the web from both GitHub and Bioconductor.

  16. Demographic knowledge and nation-building: the Peruvian census of 1940.

    Science.gov (United States)

    López, Raúl Necochea

    2010-09-01

    The demographers who organized the 1940 census of Peru portrayed the increasingly mixed-race Peruvian population as indicative of the breaking down of cultural barriers to the emergence of a robust Peruvian identity, a process that, they claimed, would lead to greater national development. This paper analyzes the ways in which demographers constructed cultural heterogeneity as a potential national asset. This reveals how scientific knowledge of miscegenation affected the formation of a nationalist project in the second half of the twentieth century, and also how demographers' ideological commitments to socialism shaped scientific practice.

    As an important approach to the realization of agricultural sustainable development, multifunctionality has become a hot spot in the field of urban agriculture. Taking 13 agricultural counties of Beijing City as the assessing units, this study selects 10 assessing index from ecological, economic and social aspects, determines the index weight using Analytic Hierarchy Process (AHP) method, and establishes an index system for the integrated agricultural function. Based on standardized data from agricultural census and remote sensing, the integrated function and multifunctionality of urban agriculture in Beijing City are assessed through the index grade mapping. The results show that agricultural counties with the highest score in ecological, economic, and social function are Yanqing, Changping, and Miyun, respectively; and the greatest disparity among those counties is economic function, followed by social and ecological function. Topography and human disturbance may be the factors that affect integrated agricultural function. The integrated agricultural function of Beijing rises at the beginning then drops later with the increase of mean slope, average altitude, and distance from the city. The whole city behaves balance among ecological, economic, and social functions at the macro level, with 8 out of the 13 counties belonging to ecology-society-economy balanced areas, while no county is dominant in only one of the three functions. On the micro scale, however, different counties have their own functional inclination: Miyun, Yanqing, Mentougou, and Fengtai are ecology-society dominant, and Tongzhou is ecology-economy dominant. The agricultural multifunctionality in Beijing City declines from the north to the south, with Pinggu having the most significant agricultural multifunctionality. The results match up well with the objective condition of Beijing's urban agriculture planning, which has proved the methodological rationality of the assessment to a certain extent

  5. Development of a stationary carbon emission inventory for Shanghai using pollution source census data

    Science.gov (United States)

    Li, Xianzhe; Jiang, Ping; Zhang, Yan; Ma, Weichun

    2016-03-01

    This study utilizes 521,631 activity data points from the 2007 Shanghai Pollution Source Census to compile a stationary carbon emission inventory for Shanghai. The inventory generated from our dataset shows that a large portion of Shanghai's total energy use consists of coal-oriented energy consumption. The electricity and heat production industries, iron and steel mills, and the petroleum refining industry are the main carbon emitters. In addition, most of these industries are located in Baoshan District, which is Shanghai's largest contributor of carbon emissions. Policy makers can use the enterpriselevel carbon emission inventory and the method designed in this study to construct sound carbon emission reduction policies. The carbon trading scheme to be established in Shanghai based on the developed carbon inventory is also introduced in this paper with the aim of promoting the monitoring, reporting and verification of carbon trading. Moreover, we believe that it might be useful to consider the participation of industries, such as those for food processing, beverage, and tobacco, in Shanghai's carbon trading scheme. Based on the results contained herein, we recommend establishing a comprehensive carbon emission inventory by inputting data from the pollution source census used in this study.

    The development of computer systems that support the geography of the census in Canada is described. The authors "present proposals for the 1991 Census that increase the level of automation, whether the geography changes or not. In addition, opportunities for change and improvement, should the geography change, are outlined. To minimize the risks involved, it is important to give these different proposals serious consideration early in the planning of a census." PMID:12341362

    1991-11-01

    The correlates of suicide rates were determined by conducting a multivariate study of sociodemographic indicators and suicide rates of 261 Canadian census divisions. Twenty-one sociodemographic variables were entered into a stepwise multiple linear regression to develop a model for suicide rates. The important variables were mortality rate for all causes of death, the age of the population, average family income, population density, proportion with no religious affiliation, proportion of Francophones, unemployment, immigration, proportion of Native people, a regional effect for British Columbia and the north, and growth by mobility, explaining 62% of the observed variation. This spatial ecologic analysis highlights the importance of cultural differences in explaining the variation of suicide rates. The analysis supports the previously found negative relationship between income and suicide while contrasting from previous studies in determining a inverse relationship with unemployment and an inverse relationship with the age distribution.

    Full Text Available Mark M Smith,1 Steven H Rose,1 Darrell R Schroeder,2 Timothy R Long1 1Department of Anesthesiology, Mayo Clinic College of Medicine, Rochester, MN, USA; 2Division of Biomedical Statistics and Informatics, Mayo Clinic College of Medicine, Rochester, MN, USA Purpose: Increasing the diversity of the United States (US physician workforce to better represent the general population has received considerable attention. The purpose of this study was to compare medical student race data to that of the US general population. We hypothesized that race demographics of medical school matriculants would reflect that of the general population. Patients and methods: Published race data from the United States Census Bureau (USCB 2010 census and the 2011 Association of American Medical Colleges (AAMC allopathic medical school application and enrollment by race and ethnicity survey were analyzed and compared. Race data of enrolled medical students was compared to race data of the general population within geographic regions and subregions. Additionally, race data of medical school applicants and matriculants were compared to race data of the overall general population. Results: Race distribution within US medical schools was significantly different than race distribution for the overall, regional, and subregional populations of the US (P<0.001. Additionally, the overall race distribution of medical school applicants differed significantly to the race distribution of the general population (P<0.001. Conclusion: This study demonstrated that race demographics of US medical school applicants and matriculants are significantly different from that of the general population, and may be resultant of societal quandaries present early in formal education. Initiatives targeting underrepresented minorities at an early stage to enhance health care career interest and provide academic support and mentorship will be required to address the racial disparity that exists in US

    Full Text Available This study investigates direct and indirect family, peer, school, and neighborhood effects on adolescents’ civic engagement utilizing data from the 1999 IEA Civic Education Study and the U.S. Census. The nationally representative sample consists of 2,729 students from 119 schools in the U.S. Multi-level regression techniques provide precise estimates of the separate and shared impact of each context on adolescents’ civic engagement. Individual students’ civic experiences and discourse in school and at home predict higher civic engagement, although the effects of these experiences vary based on the larger school and neighborhood contexts. Overall, interactive effects indicate that students who may traditionally be deemed at a disadvantage (either because of poor school or neighborhood conditions experience more benefits from increases in civic learning opportunities than do more advantaged students. Suggestions are made for secondary analyses of ICCS (the IEA civic education study of 2009.

Agriculture is no longer simply an activity that produces commodities for local, regional, national, or international markets. Indeed, in the OECD countries, commodity abundance, not commod...

  15. Survey of the distributions of population and agricultural produce, etc. and the application for population dose evaluation

    International Nuclear Information System (INIS)

    The computer model CARIEN to calculate the population doses due to all LWRs in Japan needs the distributions of population and agricultural produce around the nuclear installations. These distributions were presumed to be obtainable from national censuses, and a case-study survey was carried out in 1976 for the area up to 1000 km from the JAERI Tokai Research Establishment. The present report describes the survey and its results, and then discusses applicability of the censuses for population dose evaluation. The national censuses of population and foodstuffs were found to be sufficient for determining these distributions and predicting the future population changes. Results indicated the following: a) the population and agricultural produce around little contribute to the population doses, b) the contributions of leafy vegetables and cow's milk are important compared with inhalation, and c) if such as rice, egg and pork concentrate radionuclides to the same extent as leafy vegetables or milk, these are also important.

  16. A Global Census of Marine Life on Seamounts: are They Really Oases in the Ocean?

    Science.gov (United States)

    Consalvey, M.; Clark, M.; Rowden, A.; Stocks, K.

    2006-12-01

    Seamounts have been referred to as oases in the ocean, yet our knowledge is such that this notion can neither be refuted nor accepted. We know that seamounts can support high levels of biodiversity and endemism, that they can play an important role in patterns of marine biogeography, and that they can be highly productive ecosystems acting as feeding grounds for fishes, marine mammals and seabirds. However, our current state of knowledge is such that these observations cannot be taken as generalisations. Under the umbrella of the Census of Marine Life the project CenSeam is conducting a global census of marine life on seamounts, and working towards quantifying what is known, unknown, and will never be known. Seamounts are found in every ocean of the world but of the estimated 100 000, less than 400 have been sampled, and of these, less than 100 in sufficient biological detail. Furthermore, the global sampling effort has been geographically biased - high latitude as well as equatorial seamounts are currently under sampled and the majority of sampled seamounts have summit depths of less than 500m, sampling being limited by practical and financial capabilities. Through uniting the active seamount research community CenSeam aims to establish, at a global scale, the roles that seamounts play in the biogeography, biodiversity, productivity and evolution of marine organisms in order to determine the effect and contribution of seamounts to the global oceanic ecosystem. Recognising that it is not feasible to sample all the world's seamounts, future sampling efforts must be standardised and strategically guided, through assessing the current state of knowledge, to fill critical knowledge gaps and target understudied regions and types of seamounts. This paper will synthesise the current state of seamount knowledge and critically evaluate the global sampling effort stimulating discussion about the future of seamount research and associated methodology and data analysis.

    1977-12-01

    As part of a program to characterize the plant and animal life of the Laboratory site and surrounding areas, two breeding bird census plots were established in 1977 to document the occurrence and abundance of breeding species in two extreme successional stages of Long Island oak-pine forest. A 9.3-hectare plot located near the northeastern corner of the Laboratory site is composed of second growth oak-pine forest in a late successional stage. The second plot measures 9.7 hectares and is located in the scrub oak-pitch pine barrens at Westhampton. Each plot was surveyed with a transit and steel tape and marked with wooden stakes at 100-foot intervals. Quantitative vegetational surveys were made in each plot and all plant species identified. Tree composition was measured as a function of species and size. Shrub density, percent of ground cover and percent of canopy were also measured. The Laboratory plot contained 2100 trees of five species per hectare, 72% ground cover and 84% canopy coverage. The Westhampton plot contained only one tree species, Pitch Pine, at 366 trees per hectare, 92% ground cover and no canopy. Twelve census trips, mostly of two to three hour duration, were made in each plot. Each bird observed was located on a scale map of the plot. At the end of the season, the number of territories was determined from the distribution of sightings. Eighteen territorial bird species were found in the Laboratory plot with between 479 and 629 territorial males per km/sup 2/. In Westhampton, only five breeding species were present. Density was between 312 and 374 males per km/sup 2/. The Rufous-sided Towhee was the most common species in both plots. Future studies will document changes in both bird and plant species composition and abundance.

    We present a complete census of all 263 Herschel-detected sources within the HST Frontier Fields (HFF), a deep multi-filter HST programme covering six massive lensing clusters. We provide a robust legacy catalogue of Herschel fluxes, primarily based on imaging from the Herschel Lensing Survey (HLS) and PEP/HerMES Key Programmes. Photometry is derived via a simultaneous PSF-fit using priors from archival Spitzer imaging. We optimally combine Herschel, Spitzer and WISE infrared (IR) photometry with data from HST, VLA and ground-based observatories, identifying optical counterparts to gain source redshifts. Hence for each Herschel-detected source we also present magnification factor (mu), intrinsic IR luminosity and characteristic dust temperature, providing a comprehensive view of dust-obscured star formation within the HFF. We demonstrate the utility of our catalogues through an exploratory overview of HST morphologies for the IR-bright population. In particular we briefly describe the highest redshift (z>2.5)...

  19. Objectively measured residential environment and self-reported health: a multilevel analysis of UK census data.

    Directory of Open Access Journals (Sweden)

    Frank Dunstan

    Full Text Available Little is known about the association between health and the quality of the residential environment. What is known is often based on subjective assessments of the environment rather than on measurements by independent observers. The aim of this study, therefore, was to determine the association between self-reported general health and an objectively assessed measure of the residential environment. We studied over 30,000 residents aged 18 or over living in 777 neighbourhoods in south Wales. Built environment quality was measured by independent observers using a validated tool, the Residential Environment Assessment Tool (REAT, at unit postcode level. UK Census data on each resident, which included responses to a question which assessed self-reported general health, was linked to the REAT score. The Census data also contained detailed information on socio-economic and demographic characteristics of all respondents and was also linked to the Welsh Index of Multiple Deprivation. After adjusting for both the individual characteristics and area deprivation, respondents in the areas of poorest neighbourhood quality were more likely to report poor health compared to those living in areas of highest quality (OR 1.36, 95% confidence interval 1.22-1.49. The particular neighbourhood characteristics associated with poor health were physical incivilities and measures of how well the residents maintained their properties. Measures of green space were not associated with self-reported health. This is the first full population study to examine such associations and the results demonstrate the importance for health of the quality of the neighbourhood area in which people live and particularly the way in which residents behave towards their own and their neighbours' property. A better understanding of causal pathways that allows the development of interventions to improve neighbourhood quality would offer significant potential health gains.

  20. The census of complex organic molecules in the solar-type protostar IRAS16293-2422

    International Nuclear Information System (INIS)

    Complex organic molecules (COMs) are considered to be crucial molecules, since they are connected with organic chemistry, at the basis of terrestrial life. More pragmatically, they are molecules which in principle are difficult to synthesize in harsh interstellar environments and, therefore, are a crucial test for astrochemical models. Current models assume that several COMs are synthesized on lukewarm grain surfaces (≳30-40 K) and released in the gas phase at dust temperatures of ≳100 K. However, recent detections of COMs in ≲20 K gas demonstrate that we still need important pieces to complete the puzzle of COMs formation. Here, we present a complete census of the oxygen- and nitrogen-bearing COMs, previously detected in different Interstellar Medium (ISM) regions, toward the solar-type protostar IRAS16293-2422. The census was obtained from the millimeter-submillimeter unbiased spectral survey TIMASSS. Of the 29 COMs searched for, 6 were detected: methyl cyanide, ketene, acetaldehyde, formamide, dimethyl ether, and methyl formate. Multifrequency analysis of the last five COMs provides clear evidence that they are present in the cold (≲30 K) envelope of IRAS16293-2422, with abundances of 0.03-2 × 10–10. Our data do not allow us to support the hypothesis that the COMs abundance increases with increasing dust temperature in the cold envelope, as expected if COMs were predominately formed on lukewarm grain surfaces. Finally, when also considering other ISM sources, we find a strong correlation over five orders of magnitude between methyl formate and dimethyl ether, and methyl formate and formamide abundances, which may point to a link between these two couples of species in cold and warm gas.

    The abundance of compact, massive, early-type galaxies (ETGs) provides important constraints to galaxy formation scenarios. Thanks to the area covered, depth, excellent spatial resolution and seeing, the ESO Public optical Kilo Degree Survey (KiDS), carried out with the VLT Survey Telescope, offers a unique opportunity to conduct a complete census of the most compact galaxies in the Universe. This paper presents a first census of such systems from the first 156 deg2 of KiDS. Our analysis relies on g-, r- and i-band effective radii (Re), derived by fitting galaxy images with point spread function (PSF)-convolved Sérsic models, high-quality photometric redshifts, zphot, estimated from machine learning techniques, and stellar masses, M⋆, calculated from KiDS aperture photometry. After massiveness ({M_{⋆}}≳ 8 × 10^{10} M_{⊙}) and compactness ({R_e}≲ 1.5 kpc in g, r and i bands) criteria are applied, a visual inspection of the candidates plus near-infrared photometry from VIKING-DR1 are used to refine our sample. The final catalogue, to be spectroscopically confirmed, consists of 92 systems in the redshift range z ˜ 0.2-0.7. This sample, which we expect to increase by a factor of 10 over the total survey area, represents the first attempt to select massive supercompact ETGs (MSCGs) in KiDS. We investigate the impact of redshift systematics in the selection, finding that this seems to be a major source of contamination in our sample. A preliminary analysis shows that MSCGs exhibit negative internal colour gradients, consistent with a passive evolution of these systems. We find that the number density of MSCGs is only mildly consistent with predictions from simulations at z > 0.2, while no such system is found at z < 0.2.

    Image classification will still be a long way in the future, although it has gone almost half a century. In fact, researchers have gained many fruits in the image classification domain, but there is still a long distance between theory and practice. However, some new methods in the artificial intelligence domain will be absorbed into the image classification domain and draw on the strength of each to offset the weakness of the other, which will open up a new prospect. Usually, networks play the role of a high-level language, as is seen in Artificial Intelligence and statistics, because networks are used to build complex model from simple components. These years, Bayesian Networks, one of probabilistic networks, are a powerful data mining technique for handling uncertainty in complex domains. In this paper, we apply Tree Augmented Naive Bayesian Networks (TAN) to texture classification of High-resolution remote sensing images and put up a new method to construct the network topology structure in terms of training accuracy based on the training samples. Since 2013, China government has started the first national geographical information census project, which mainly interprets geographical information based on high-resolution remote sensing images. Therefore, this paper tries to apply Bayesian network to remote sensing image classification, in order to improve image interpretation in the first national geographical information census project. In the experiment, we choose some remote sensing images in Beijing. Experimental results demonstrate TAN outperform than Naive Bayesian Classifier (NBC) and Maximum Likelihood Classification Method (MLC) in the overall classification accuracy. In addition, the proposed method can reduce the workload of field workers and improve the work efficiency. Although it is time consuming, it will be an attractive and effective method for assisting office operation of image interpretation.

    1990-09-01

    This report contains a set of recommendations prepared by Oak Ridge National Laboratory (ORNL) for the US Bureau of the Census pertaining to technology innovation and management. Technology has the potential to benefit the Bureau's data collection, capture, processing, and analysis activities. The entire Bureau was represented from Decennial Census to Economic Programs and various levels of Bureau management and numerous experts in technology. Throughout the Bureau, workstations, minicomputers, and microcomputers have found their place along side the Bureau's mainframes. The Bureau's new computer file structure called the Topologically Integrated Geographic Encoding and Referencing data base (TIGER) represents a major innovation in geographic information systems and impressive progress has been made with Computer Assisted Telephone Interviewing (CATI). Other innovations, such as SPRING, which aims to provide Bureau demographic analysts with the capability of interactive data analysis on minicomputers, are in the initial stages of development. Recommendations fall into five independent, but mutually beneficial categories. (1) The ADP Steering Committee be disbanded and replaced with The Technology Forum. (2) Establishment of a Technology Review Committee (TRC), to be composed of technology experts from outside the Bureau. (3) Designate technological gurus. These individuals will be the Bureau's experts in new and innovative technologies. (4) Adopt a technology innovation process. (5) Establish an Advanced Technology Studies Staff (ATSS) to promote technology transfer, obtain funding for technological innovation, manage innovation projects unable to find a home in other divisions, evaluate innovations that cut across Bureau organizational boundaries, and provide input into Bureau technology analyses.

    Table obssum.dat contains an observing summary for all pulsars in the LOFAR census sample. DM measurements and mean flux densities in 110-188MHz frequency range are listed for 158 detected sources. For the non-detected pulsars the upper limits on mean flux density values are given. Spectral fits for 165 pulsars with flux densities measured at more than one frequency (census or literature) are presented in table1pl.dat (a single power-law spectral model, 1PL), table2pl.dat (a power-law with one break, 2PL) or in table3pl.dat (2 breaks, 3PL). For 1PL models, the measured flux density values were modeled as random variables, normally distributed in base 10 log space with meanlgS=lg(S0)+a*lg(f/f0) and dispersion sigmalgS. For the spectra consisting of small number of measurements, sigma_lgS was set by the reported flux density errors. For the spectra consisting of larger number of measurements, an additional scatter (sigmaunknlgS) was added in quadrature to sigma_lgS and fitted for. This additional parameter represents intrinsic flux variability or any kind of unaccounted propagation or instrumental error. For 2PL models, mean_logS was defined as lg(S0)+(alo)*lg(f/f0) for ffbr. For 3PL models mean_lgS was modified accordingly. A 2PL or 3PL model was preferred over a 1PL model in the cases where either of the former gave a significantly smaller sigmaunknlgS. (5 data files).

    To quantitatively assess disease burden due to tuberculosis between populations residing in and outside of urban informal settlements in Rio de Janeiro, Brazil, we compared disability-adjusted life years (DALYs), or "DALY-gap." Using the 2010 Brazilian census definition of informal settlements as aglomerados subnormais (AGSN), we allocated tuberculosis (TB) DALYs to AGSN vs non-AGSN census tracts based on geocoded addresses of TB cases reported to the Brazilian Information System for Notifiable Diseases in 2005 and 2010. DALYs were calculated based on the 2010 Global Burden of Disease methodology. DALY-gap was calculated as the difference between age-adjusted DALYs/100,000 population between AGSN and non-AGSN. Total TB DALY in Rio in 2010 was 16,731 (266 DALYs/100,000). DALYs were higher in AGSN census tracts (306 vs 236 DALYs/100,000), yielding a DALY-gap of 70 DALYs/100,000. Attributable DALY fraction for living in an AGSN was 25.4%. DALY-gap was highest for males 40-59 years of age (501 DALYs/100,000) and in census tracts with <60% electricity (12,327 DALYs/100,000). DALY-gap comparison revealed spatial and quantitative differences in TB burden between slum vs non-slum census tracts that were not apparent using traditional measures of incidence and mortality. This metric could be applied to compare TB burden or burden for other diseases in mega-cities with large informal settlements for more targeted resource allocation and evaluation of intervention programs.

  14. Detection of density-dependent effects on caribou numbers from a series of census data

    Directory of Open Access Journals (Sweden)

    Francois Messier

    1991-10-01

    Full Text Available The main objective of this paper is to review and discuss the applicability of statistical procedures for the detection of density dependence based on a series of annual or multi-annual censuses. Regression models for which the statistic value under the null hypothesis of density independence is set a priori (slope = 0 or 1, generate spurious indications of density dependence. These tests are inappropriate because low sample sizes, high variance, and sampling error consistently bias the slope when applied to a finite number of population estimates. Two distribution-free tests are reviewed for which the rejection region for the hypothesis of density independence is derived intrinsically from the data through a computer-assisted permutation process. The "randomization test" gives the best results as the presence of a pronounced trend in the sequence of population estimates does not affect test results. The other non-parametric test, the "permutation test", gives reliable results only if the population fluctuates around a long-term equilibrium density. Both procedures are applied to three sets of data (Pukaskwa herd, Avalon herd, and a hypothetical example that represent quite divergent population trajectories over time.

    2007-01-01

    The first paper in this series took a direct census of energy input from the known OB stars in the Carina Nebula, and in this paper we study the global properties of the surrounding nebulosity. We find that the total IR luminosity of Carina is about 1.2E7 Lsun, accounting for only about 50-60% of the known stellar luminosity from Paper I. Similarly, the ionizing photon luminosity -- (abridged; many important details omitted). Synchronized star formation around the periphery of Carina provides a strong case that star formation here was indeed triggered by stellar winds and UV radiation. This second generation appears to involve a cascade toward preferentially intermediate- and low-mass stars, but this may soon change when eta Car and its siblings explode. If the current reservoir of atomic and molecular gas can be tapped at that time, massive star formation may be rejuvinated around the periphery of Carina much as if it were a young version of Gould's Belt. Also, when these multiple SNe occur, the triggered se...

  18. Environmental assessment of Swedish agriculture

    International Nuclear Information System (INIS)

    This article describes an environmental assessment of Swedish agriculture, including upstream and downstream effects. The analysis is based on environmentally extended input-output analysis, but it is also supplemented with data from other sources. The analysis shows that direct effects by the Swedish agriculture are the most important, while indirect effects from other sources including mobile and impacts abroad are also considerable. The most important impacts from Swedish agriculture according to the analysis are eutrophication, global warming and resource use. The agricultural sector produces a large share of the Swedish emissions causing both global warming and eutrophication. In addition, current agricultural practice causes problems with loss of biodiversity. The most important actors in the sector are agriculture itself, but also all actors using fossil fuels: primarily the transport sector and the energy sector. In addition, consumers are important since they can influence the composition of agricultural production. The analysis shows the importance of including upstream and downstream effects when analysing the environmental impacts from a sector. (author)

    The REsolved Spectroscopy of a Local VolumE (RESOLVE) survey is measuring either velocity dispersions or rotation velocities for ~1500 galaxies and ~200 multi-galaxy groups within >50,000 cubic Mpc of the z~0 universe, above a galaxy baryonic mass limit of ~10^9 Msun. Our kinematic census combines multi-slit, IFU, Fabry-Perot, long-slit, and radio linewidth data from the SOAR, SALT, Gemini, AAT, GBT, and Arecibo telescopes, with telescope/instrument combinations optimized for individual galaxy properties. We present a status update of the data taken, particularly focusing on the RESOLVE Early Science region overlapping Stripe 82. We also discuss challenges for dynamical measurements including measuring galaxy inclinations, determining the mix of support from rotational and random motions, and measuring dynamical masses for groups with few members. Finally, we conclude with a preliminary velocity function for the RESOLVE Early Science region.

  2. From darwin to the census of marine life: marine biology as big science.

    Directory of Open Access Journals (Sweden)

    Niki Vermeulen

    Full Text Available With the development of the Human Genome Project, a heated debate emerged on biology becoming 'big science'. However, biology already has a long tradition of collaboration, as natural historians were part of the first collective scientific efforts: exploring the variety of life on earth. Such mappings of life still continue today, and if field biology is gradually becoming an important subject of studies into big science, research into life in the world's oceans is not taken into account yet. This paper therefore explores marine biology as big science, presenting the historical development of marine research towards the international 'Census of Marine Life' (CoML making an inventory of life in the world's oceans. Discussing various aspects of collaboration--including size, internationalisation, research practice, technological developments, application, and public communication--I will ask if CoML still resembles traditional collaborations to collect life. While showing both continuity and change, I will argue that marine biology is a form of natural history: a specific way of working together in biology that has transformed substantially in interaction with recent developments in the life sciences and society. As a result, the paper does not only give an overview of transformations towards large scale research in marine biology, but also shines a new light on big biology, suggesting new ways to deepen the understanding of collaboration in the life sciences by distinguishing between different 'collective ways of knowing'.

  3. Anthropological and demographic dimensions of the Kurdish question: Findings from census and survey data

    2011-01-01

    Full Text Available Within this study, demographic and anthropological differences between the Kurdish group and the rest of the Turkish population are presented while existing approaches on the Kurdish question based on economic and political factors are critically evaluated. Using results of the 1945 Census an inventory of all language groups in Turkey is given together with their respective ‘literacy rates’ and ‘prevalence of knowledge of Turkish’, which reveal temporal differences in terms of entrance into the demographic transition and give hints as to why some ethnic groups have adopted the Turkish identity while some other groups have remained outside the ‘Turkish core’. Recent data from the TDHS, on the other hand, is used to analyze ‘fertility’ and ‘prevalence of consanguineous marriages’ among the Kurdish population. While Kurds who use Turkish as either main or second language converge to the rest of the population in terms of both fertility decline and the matrilateral swing among consanguineous marriages, among Kurds who do not speak Turkish at all the mentioned rates increase in the opposite direction. The Turkish and Kurdish family structures are evaluated within the framework of Emmanuel Todd’s family types with special consideration on the effects of consanguineous marriages and the patrilateral inclination among these on the status of women.

    We have obtained optical and near-infrared spectra of candidate members of the star-forming clusters IC 348 and NGC 1333. We classify 100 and 42 candidates as new members of the clusters, respectively, which brings the total numbers of known members to 478 and 203. We also have performed spectroscopy on a large majority of the previously known members of NGC 1333 in order to provide spectral classifications that are measured with the same scheme that has been applied to IC 348 in previous studies. The new census of members is nearly complete for Ks<16.8 at Aj<1.5 in IC 348 and for Ks<16.2 at Aj<3 in NGC 1333, which correspond to masses of <=0.01 Msun for ages of 3 Myr according to theoretical evolutionary models. The faintest known members extend below these completeness limits and appear to have masses of ~0.005 Msun. In extinction-limited samples of cluster members, NGC 1333 exhibits a higher abundance of objects at lower masses than IC 348. It would be surprising if the initial mass function...

    Despite recent media and scholarly attention describing the "disappearance" of traditionally gay neighborhoods, urban scholars have yet to quantify the segregation of same-sex partners and determine whether declining segregation from different-sex partners is a wide-spread trend. Focusing on the 100 most populous places in the United States, I use data from the 2000 and 2010 Decennial Census to examine the segregation of same-sex partners over time and its place-level correlates. I estimate linear regression models to examine the role of four place characteristics in particular: average levels of education, aggregate trends in the family life cycle of same-sex partners, violence and social hostility motivated by sexual orientation bias, and representation of same-sex partners in the overall population. On average, same-sex partners were less segregated from different-sex partners in 2010 than in 2000, and the vast majority of same-sex partners lived in environments of declining segregation. Segregation was lower and declined more rapidly in places that had a greater percentage of graduate degree holders. In addition, segregation of female partners was lower in places that had a greater share of female partner households with children. These findings suggest that sexual orientation should be considered alongside economic status, race, and ethnicity as an important factor that contributes to neighborhood differentiation and urban spatial inequality.

    Described are kits and methods useful for detection of seven agricultural pathogens (BPSV; BHV; BVD; FMDV; BTV; SVD; and VESV) in a sample. Genomic sequence information from 7 agricultural pathogens was analyzed to identify signature sequences, e.g., polynucleotide sequences useful for confirming the presence or absence of a pathogen in a sample. Primer and probe sets were designed and optimized for use in a PCR based, multiplexed Luminex assay to successfully identify the presence or absence of pathogens in a sample.

  7. THE MAIN DEMOGRAPHICS CHANGES IN THE POPULATION OF BACĂU COUNTY AT THE LAST CENSUS

    Full Text Available Livestock population and its structure is the starting point for all development strategies at both micro and macro level, reason for which accurate knowledge of it is one of the main objectives of official statistics in each state. The analysis aims to highlight the major changes produced after the 90s in terms of population of Bacău county and its structure, with time effects on economic and social activity. Both the 2002 and 2011 census, Bacău was top of the list with an absolute decrease of the population. This was a concern as it has emerged over time as a stable phenomenon. The main reason for the decrease was due to external migration of the population and secondly because of the internal migration flows of population moving towards large economic centers in the country and abroad that attract labor. As most of the migrants are young and active age groups, this phenomena has led to an aging population and to imbalances that can be observed in the age pyramid, with negative effects becoming larger in the future.

    We report on the presence of large amounts of million-degree gas in the Milky Way's interstellar and circum-galactic medium. This gas (1) permeates both the Galactic plane and the halo, (2) extends to distances larger than 60-200 kpc from the center, and (3) its mass is sufficient to close the Galaxy's baryon census. Moreover, we show that a vast, $\\sim 6$ kpc radius, spherically-symmetric central region of the Milky Way above and below the 0.16 kpc thick plane, has either been emptied of hot gas or the density of this gas within the cavity has a peculiar profile, increasing from the center up to a radius of $\\sim 6$ kpc, and then decreasing with a typical halo density profile. This, and several other converging pieces of evidence, suggest that the current surface of the cavity, at 6 kpc from the Galaxy's center, traces the distant echo of a period of strong nuclear activity of our super-massive black-hole, occurred about 6 Myrs ago.

    The MPF mission will provide a statistical census of exoplanets with masses greater than 0.1 Earth-masses and orbital separations ranging from 0.5AU to infinity. This includes analogs to all the Solar System's planets except for Mercury, as well as most types of planets predicted by planet formation theories. Such a survey will provide results on the frequency of planets around all types of stars except those with short lifetimes. Close-in planets with separations < 0.5 AU are invisible to a space-based microlensing survey, but these can be found by Kepler. Other methods, including ground-based microlensing, cannot approach the comprehensive statistics on the mass and semi-major axis distribution of extrasolar planets that a space-based microlensing survey will provide. The terrestrial planet sensitivity of a ground-based microlensing survey is limited to the vicinity of the Einstein radius at 2-3 AU, and space-based imaging is needed to identify and determine the mass of the planetary host stars for the v...

    It is well known that agricultural activity has a considerable influence on hydrological processes such as run-off and its regime, erosion and sedimentation, transport of dissolved chemicals, etc. But the influence goes beyond hydrology. Water just plays the role of an agent or carrier in geoecosystems. That is why we have chosen the watershed as a natural territorial unit where the components are united by hydrological processes. The policy usually adopted for normal agricultural dev...

The objective of this paper is to highlight the uniqueness and credible attributes of the exercise: and to make recommendations for subsequent census exercisein the country. The state commisioners were interviewed. NPC (National Population Commision websites was visited and documents from the NPC office were perused. Literatures on National Population Commision were also read and used. The structure, system and organization can be compared to thatof developed countries. The organisation now use new and improved technology. The activities of the organisation are more reliable as enumeration areas were demarcated to scales. AFIS (Automated Fingerprint Identification System were implored and Geographic Information System was intended to be used to store the results. Suffice it to say that despite all efforts made by all organs of Government to create awareness and plan logistics, some challenges were still encountered. Nevertheless, there were also some positive responses as it threw more light on the number, quality, type and design of houses in various communities. All organs of the governments were engaged. From planning to execution, adequate awareness and preparation were made to avoid the usual riddles that characterized the previous exercises. The total population is 140, 003,542 unevenly distributed on the territory.

    SONYC, short for "Substellar Objects in Nearby Young Clusters", is a survey program to provide a census of the substellar population in nearby star forming regions. We have conducted deep optical and near-infrared photometry in five young regions (NGC1333, rho Ophiuchi, Chamaeleon-I, Upper Sco, and Lupus-3), combined with proper motions, and followed by extensive spectroscopic campaigns with Subaru and VLT, in which we have obtained more than 700 spectra of candidate low-mass objects. We have identified and characterized more than 60 new substellar objects, among them a handful of objects with masses close to, or below the Deuterium burning limit. Through SONYC and surveys by other groups, the substellar IMF is now well characterized down to ~ 5 - 10 MJup, and we find that the ratio of the number of stars with respect to brown dwarfs lies between 2 and 6. A comprehensive survey of NGC 1333 reveals that, down to ~5MJup, free-floating objects with planetary masses are 20-50 times less numerous than stars, i.e. ...

    2012-01-01

    We investigate the nature of 48 low-level stellar overdensities (from Froebrich, Scholz, and Raftery catalogue - FSR07) projected towards the Galactic anticentre and derive fundamental parameters for the confirmed clusters, thus improving the open cluster (OC) census in that direction. Parameters are derived with field-star decontaminated photometry, colour-magnitude filters and stellar radial density profiles. Among the 48 targets, we identified 18 star clusters, 6 previously studied OCs, and 7 probable clusters that require deeper photometry to establish the nature. We discovered 7 new clusters, 6 of them forming an association of clusters with BPI 14, FSR 777, Kronberger 1, and Stock 8 in the region of the nebula IC 417 and related to the Aur OB2 association, and one embedded in the nebula Sh2-229. We also derive parameters for these three non-FSR07 clusters, because they are important in determining the structure of the Galactic anticentre. Thus, 58 objects are analysed in this work and we could derive fu...

    We present a study of the HII regions in the galaxy NGC 6754 from a two pointing mosaic comprising 197,637 individual spectra, using Integral Field Spectrocopy (IFS) recently acquired with the MUSE instrument during its Science Verification program. The data cover the entire galaxy out to ~2 effective radii (re ), sampling its morphological structures with unprecedented spatial resolution for a wide-field IFU. A complete census of the H ii regions limited by the atmospheric seeing conditions was derived, comprising 396 individual ionized sources. This is one of the largest and most complete catalogue of H ii regions with spectroscopic information in a single galaxy. We use this catalogue to derive the radial abundance gradient in this SBb galaxy, finding a negative gradient with a slope consistent with the characteristic value for disk galaxies recently reported. The large number of H ii regions allow us to estimate the typical mixing scale-length (rmix ~0.4 re ), which sets strong constraints on the proposed...

    Population monitoring is vital for conservation and management. However, simple counts of animals can be misleading and this problem is exacerbated in seals (pinnipeds) where individuals spend much time foraging away from colonies. We analyzed a 13-year-series of census data of Galapagos sea lions (Zalophus wollebaeki) from the colony of Caamaño, an islet in the center of the Galapagos archipelago where a large proportion of animals was individually marked. Based on regular resighting efforts during the cold, reproductive (cold-R; August to January) and the warm, non-reproductive (warm-nR; February to May) season, we document changes in numbers for different sex and age classes. During the cold-R season the number of adults increased as the number of newborn pups increased. Numbers were larger in the morning and evening than around mid-day and not significantly influenced by tide levels. More adults frequented the colony during the warm-nR season than the cold-R season. Raw counts suggested a decline in numbers over the 13 years, but Lincoln-Petersen (LP-) estimates (assuming a closed population) did not support that conclusion. Raw counts and LP estimates were not significantly correlated, demonstrating the overwhelming importance of variability in attendance patterns of individuals. The probability of observing a given adult in the colony varied between 16% (mean for cold-R season) and 23% (warm-nR season) and may be much less for independent 2 to 4 year olds. Dependent juveniles (up to the age of about 2 years) are observed much more frequently ashore (35% during the cold-R and 50% during the warm-nR seasons). Simple counts underestimate real population size by a factor of 4–6 and may lead to erroneous conclusions about trends in population size. PMID:27148735

    Full Text Available What is the future of internal medicine in Italy? Which competencies? Which potentialities? To this aim Ligurian FADOI Regional Society performed a census among 18 Internal Medicine Wards (IMWs in non-teaching Ligurian Hospital. We administered, by email, a questionnaire to the heads of IMWs. Data about staffing, equipment, skills, competencies and productivity during 2011 were collected from 1st to 31st November 2012. A total of 15/18 (83.3% chiefs answered to the questionnaire. The number of beds was largely variable among the wards. In 2011, mean diagnosis-related group (DRG-weight was 1.09 (range 0.91-1.6 and that revenues/costs ratio much higher than 1.5. Staff was quite adequate to standards defined by current law, only 33% has got a doctor:patients ratio superior to 1:6.4. However, annual hospitalizations exceed the availability of beds in medicine and the complexity of the patients would require a lower doctor:patients ratio, at least for a group of patients. In fact, 4 wards have a progressive care organization with a defined area for more seriously ill patients. Mean length of stay was 10 days. Expertise was wide, covering almost all medical sub-specialties. Acquired skills such as abdominal, heart and vascular ultrasounds, invasive procedures and their comprehensive knowledge make internists complete and cost-effective specialists. IMWs, as a concentrate of medical knowledge and skills, are the natural destination of current patients with co-morbidities. Staffing and number of beds should be revised according to this new demand. Their revenues/costs ratio resulted favorable and their global approach to patients and not to disease can be useful for resource rationalization. Wider and further studies are needed to improve the awareness of stakeholders about Internal Medicine.

  11. Censusing and modeling the dynamics of a population of eastern hemlock (Tsuga canadensis L.) using remote sensing

    Science.gov (United States)

    Lamar, W. Robert

    A population of eastern hemlock (Tsuga canadensis L.) was censused from the ground using traditional field methods and from the air using large scale, high-resolution, aerial imagery in the early spring of 1997, 1998 and 1999. A manual crown survey map of the population, prepared from aerial imagery, was compared to a traditional field census. Over 60% of the individuals measured on the ground were not detected in the aerial census. Tree size, crown density and crown position all played roles in determining a crown's visibility from the air. Nearly all large, upper canopy hemlocks were visible in the aerial census. An important minority of small, lower canopy hemlocks were also visible in the aerial census. An automated spatial segmentation procedure was developed to identify and measure individual population units, or blobs, within the forest population. A blob was defined as a distinct portion of crown segmented from its neighbors on the basis of size, shape, and connectivity. To ensure the comparability of multi-year segmentation maps, an automated blob reconciliation procedure was also developed to make certain that no hemlock pixels were assigned to different blobs in different years. Following spatial segmentation and reconciliation, a large majority of hemlock blobs (˜64--72%) were found to be closely associated with ground referenced, manually delineated, individual hemlock crowns. The remaining blobs consisted of spatially distinct parts of a crown or closely clumped multiple crowns. Matrix population models were constructed from the ground-derived and aerial-derived population data. Matrix analysis produced a number of useful population characteristics including overall population growth rate (lambda), stable stage distributions, reproductive values, and sensitivity values. lambda's calculated from the aerial and ground-derived matrices were compared using randomization tests.

    In order to identify drivers of land use / land cover change (LUCC), the rate of change is often compared with environmental and socio-economic variables such as slope, soil suitability or population density. Socio-economic information is obtained from census data which are collected for individual households but are commonly presented in aggregate on the basis of geographical units as municipalities. However, a common problem, known as the modifiable areal unit problem (MAUP), is that the results of statistical analysis are not independent of the scale and the spatial configuration of the units used to aggregate the information. In this article, we evaluate how strong MAUP effects are for a study on the deforestation drivers in Mexico at municipality level. This was done by taking socio-economic variables from the 2010 Census of Mexico along with environmental variables and the rate of deforestation. As population census is given for each human settlement and environmental variables are obtained from high resolution spatial database, it was possible to aggregate the information using spatial units ("pseudo municipalities") with different sizes in order to observe the effect of scale and aggregation on the values of bivariate correlations (Pearsons r) between pairs of variables.

    Historical censuses have an enormous potential for research. In order to fully use this potential harmonization of these censuses is essential. During the last decades enormous efforts have been undertaken in digitizing the published aggregated outcomes of the Dutch historical censuses (1795-1971).

  15. Measuring the diffusion of palliative care in long-term care facilities – a death census

    Directory of Open Access Journals (Sweden)

    Santos-Eggimann Brigitte

    2009-01-01

    Full Text Available Abstract Background The dissemination of palliative care for patients presenting complex chronic diseases at various stages has become an important matter of public health. A death census in Swiss long-term care facilities (LTC was set up with the aim of monitoring the frequency of selected indicators of palliative care. Methods The survey covered 150 LTC facilities (105 nursing homes and 45 home health services, each of which was asked to complete a questionnaire for every non-accidental death over a period of six months. The frequency of 4 selected indicators of palliative care (resort to a specialized palliative care service, the administration of opiates, use of any pain measurement scale or other symptom measurement scale was monitored in respect of the stages of care and analysed based on gender, age, medical condition and place of residence. Results Overall, 1200 deaths were reported, 29.1% of which were related to cancer. The frequencies of each indicator varied according to the type of LTC, mostly regarding the administration of opiate. It appeared that the access to palliative care remained associated with cancer, terminal care and partly with age, whereas gender and the presence of mental disorders had no effect on the indicators. In addition, the use of drugs was much more frequent than the other indicators. Conclusion The profile of patients with access to palliative care must become more diversified. Among other recommendations, equal access to opiates in nursing homes and in home health services, palliative care at an earlier stage and the systematic use of symptom management scales when resorting to opiates have to become of prime concern.

  16. Disaggregate demand for conventional and alternative fuelled vehicles in the Census Metropolitan Area of Hamilton, Canada

    Science.gov (United States)

    Potoglou, Dimitrios

    The focus of this thesis is twofold. First, it offers insight on how households' car-ownership behaviour is affected by urban form and availability of local-transit at the place of residence, after controlling for socio-economic and demographic characteristics. Second, it addresses the importance of vehicle attributes, household and individual characteristics as well as economic incentives and urban form to potential demand for alternative fuelled vehicles. Data for the empirical analyses of the aforementioned research activities were obtained through an innovative Internet survey, which is also documented in this thesis, conducted in the Census Metropolitan Area of Hamilton. The survey included a retrospective questionnaire of households' number and type of vehicles and a stated choices experiment for assessing the potential demand for alternative fuelled vehicles. Established approaches and emerging trends in automobile demand modelling identified early on in this thesis suggest a disaggregate approach and specifically, the estimation of discrete choice models both for explaining car ownership and vehicle-type choice behaviour. It is shown that mixed and diverse land uses as well as short distances between home and work are likely to decrease the probability of households to own a large number of cars. Regarding the demand for alternative fuelled vehicles, while vehicle attributes are particularly important, incentives such as free parking and access to high occupancy vehicle lanes will not influence the choice of hybrids or alternative fuelled vehicles. An improved understating of households' behaviour regarding the number of cars as well as the factors and trade-offs for choosing cleaner vehicles can be used to inform policy designed to reduce car ownership levels and encourage adoption of cleaner vehicle technologies in urban areas. Finally, the Internet survey sets the ground for further research on implementation and evaluation of this data collection method.

    We perform a census of the reddest, and potentially youngest, protostars in the Orion molecular clouds using data obtained with the PACS instrument on board the Herschel Space Observatory and the LABOCA and SABOCA instruments on APEX as part of the Herschel Orion Protostar Survey (HOPS). A total of 55 new protostar candidates are detected at 70 {mu}m and 160 {mu}m that are either too faint (m{sub 24} > 7 mag) to be reliably classified as protostars or undetected in the Spitzer/MIPS 24 {mu}m band. We find that the 11 reddest protostar candidates with log {lambda}F{sub {lambda}}70/{lambda}F{sub {lambda}}24 > 1.65 are free of contamination and can thus be reliably explained as protostars. The remaining 44 sources have less extreme 70/24 colors, fainter 70 {mu}m fluxes, and higher levels of contamination. Taking the previously known sample of Spitzer protostars and the new sample together, we find 18 sources that have log {lambda}F{sub {lambda}}70/{lambda}F{sub {lambda}}24 > 1.65; we name these sources 'PACS Bright Red sources', or PBRs. Our analysis reveals that the PBR sample is composed of Class 0 like sources characterized by very red spectral energy distributions (SEDs; T{sub bol} < 45 K) and large values of sub-millimeter fluxes (L{sub smm}/L{sub bol} > 0.6%). Modified blackbody fits to the SEDs provide lower limits to the envelope masses of 0.2-2 M{sub Sun} and luminosities of 0.7-10 L{sub Sun }. Based on these properties, and a comparison of the SEDs with radiative transfer models of protostars, we conclude that the PBRs are most likely extreme Class 0 objects distinguished by higher than typical envelope densities and hence, high mass infall rates.

    Full Text Available Agriculture today is a strategic point of a country's economy, providing food based on population, development of internal and external trade and manufacturing industries by supplying raw materials. For Romania, this branch is a strong point both in terms climatic (temperate, balanced relief, soil quality and at the same time is also a way of national development and convergence of rural areas to their full potential untapped. With strong reforms, well implemented, a specific legislative framework which aims to protecting private property, Romania could reduce the low efficiency and can have a sustainable agriculture. The paper aimed to present the advantages of consuming organic products, and, on the other hand, the advantages of a country in terms of organic farming. European agriculture is a competitive, market-oriented, but also protecting the environment model.

  20. A census of dense cores in the Taurus L1495 cloud from the Herschel

    We present a catalogue of dense cores in a ˜4° × 2° field of the Taurus star-forming region, inclusive of the L1495 cloud, derived from Herschel SPIRE and PACS observations in the 70 μm, 160 μm, 250 μm, 350 μm, and 500 μm continuum bands. Estimates of mean dust temperature and total mass are derived using modified blackbody fits to the spectral energy distributions. We detect 525 starless cores of which ˜10-20 per cent are gravitationally bound and therefore presumably prestellar. Our census of unbound objects is ˜85 per cent complete for M > 0.015 M⊙ in low-density regions (AV ≲ 5 mag), while the bound (prestellar) subset is ˜85 per cent complete for M > 0.1 M⊙ overall. The prestellar core mass function (CMF) is consistent with lognormal form, resembling the stellar system initial mass function, as has been reported previously. All of the inferred prestellar cores lie on filamentary structures whose column densities exceed the expected threshold for filamentary collapse, in agreement with previous reports. Unlike the prestellar CMF, the unbound starless CMF is not lognormal, but instead is consistent with a power-law form below 0.3 M⊙ and shows no evidence for a low-mass turnover. It resembles previously reported mass distributions for CO clumps at low masses (M ≲ 0.3 M⊙). The volume density PDF, however, is accurately lognormal except at high densities. It is consistent with the effects of self-gravity on magnetized supersonic turbulence. The only significant deviation from lognormality is a high-density tail which can be attributed unambiguously to prestellar cores.

  2. Applications of radioisotopes in agriculture

    International Nuclear Information System (INIS)

    India has large population which is engaged in agriculture or related activities. With many agro-climatic zones, diversity in crops and traditional largely plant food based diets, there is need to meet these and increase agricultural production in the face of increasing constraints. Radiations and radioisotopes can contribute significantly to these developments. Mutation breeding is very useful technique in Indian context. Basic technique can be applied where a radiation source or irradiation service and facility to grow few thousand plants are available. Radiation processing can save the valuable food which is subject to spoilage by microbes and insects. Value addition by export is possible by meeting the quarantine and hygienisation conditions

    @@ Introduction The focus of research on Agricultural Economics and Management (AEM) has been switching from developed countries to developing countries. In important international journals on AEM such as "American Journal of Agricultural Economics" and "Agricultural Economics", the research objectives mainly focus on AEM problems in developing countries, e.g. the effects of globalization and liberalization on agricultural production in developing countries, and problems in agricultural resources and environmental protections in developing countries.

  14. A longitudinal study of Steller sea lion natality rates in the Gulf of Alaska with comparisons to census data.

    Steller sea lion (Eumetopias jubatus) numbers in the Western Distinct Population Segment are beginning to recover following the dramatic decline that began in the 1970s and ended around the turn of the century. Low female reproductive rates (natality) may have contributed to the decline and remain an issue of concern for this population. During the 2000s we found high natality among Steller sea lions in the Gulf of Alaska indicating a healthy population. This study extends these previous estimates over an additional three years and tests for interannual variations and long-term trends. We further examine the proportions of pups to adult females observed on the rookery and nearby haulouts during the birthing season to assess whether census data can be used to estimate natality. Open robust design multistate models were built and tested using Program MARK to estimate survival, resighting, and state transition probabilities in addition to other parameters dependent on whether or not a female gave birth in the previous year. Natality was estimated at 70% with some evidence of interannual variation but a long-term increasing or decreasing trend was not supported by the data. Bootstrap and regression comparisons of census data with natality estimates revealed no correlation between the two methods suggesting that census data are not an appropriate proxy for natality in this species. Longitudinal studies of individual animals are an appropriate method for estimating vital rates in species with variable detection over time such as the Steller sea lion. This work indicates that natality remains high in this region and is consistent with a population in recovery. PMID:25383865

  15. A preliminary census of engineering activities located in Sicily (Southern Italy) which may "potentially" induce seismicity

    The seismic events caused by human engineering activities are commonly termed as "triggered" and "induced". This class of earthquakes, though characterized by low-to-moderate magnitude, have significant social and economical implications since they occur close to the engineering activity responsible for triggering/inducing them and can be felt by the inhabitants living nearby, and may even produce damage. One of the first well-documented examples of induced seismicity was observed in 1932 in Algeria, when a shallow magnitude 3.0 earthquake occurred close to the Oued Fodda Dam. By the continuous global improvement of seismic monitoring networks, numerous other examples of human-induced earthquakes have been identified. Induced earthquakes occur at shallow depths and are related to a number of human activities, such as fluid injection under high pressure (e.g. waste-water disposal in deep wells, hydrofracturing activities in enhanced geothermal systems and oil recovery, shale-gas fracking, natural and CO2 gas storage), hydrocarbon exploitation, groundwater extraction, deep underground mining, large water impoundments and underground nuclear tests. In Italy, induced/triggered seismicity is suspected to have contributed to the disaster of the Vajont dam in 1963. Despite this suspected case and the presence in the Italian territory of a large amount of engineering activities "capable" of inducing seismicity, no extensive researches on this topic have been conducted to date. Hence, in order to improve knowledge and correctly assess the potential hazard at a specific location in the future, here we started a preliminary study on the entire range of engineering activities currently located in Sicily (Southern Italy) which may "potentially" induce seismicity. To this end, we performed: • a preliminary census of all engineering activities located in the study area by collecting all the useful information coming from available on-line catalogues; • a detailed compilation

    Full Text Available Problem statement: Jordans agricultural extension service is seriously under-staffed and its effectiveness is consequently compromised. Reservations are being expressed about the performance and capability of the agricultural extension system in Jordan. The performance of this sector has been disappointing and has failed to transfer agricultural technology to the farmers. The main objective of this study is to assess the effectiveness of Jordans agricultural extension services. Approach: The effect of extension services on olive productivity in the study area was investigated. A total number of 60 olive producers were selected to be interviewed for this study. This number was enough to achieve the study objectives. The interviewed producers were distributed almost equally within olive production locations in the study area. The sample obtained through the simple random sampling technique. The two groups had been chosen and distributed randomly into an experimental group (30 farmers; 10 for each source of extension service and control group (30 farmers. The experimental group received extension services and the control group received no extension services. Two interview-cum-structured questionnaires were designed and used to collect information and data for this study. The first instrument was designed for farmers who received extension services and the second from farmers who received no extension services. Another questionnaire was designed for administrators of extension organizations concerned with providing extension services to farmers. To find the differences that may exist between two studied groups, One Way Analysis of Variance (ANOVA, t-test and LSD test via Statistical Package for Social Sciences software (SPSS were used. The average net profit obtained from an area of one dynamo of olive farm was the main item to be considered in determining the effectiveness of agricultural extension activities. Results and Conclusion: The results of

    Full Text Available Heterogeneity in capture probabilities is known to produce bias in the dual system estimates that have been used to estimate census coverage in U.S. Censuses since 1980. Triple system estimation using an administrative records list as a third source along with the census and coverage measurement survey has the potential to produce estimates with less bias. This is particularly important for hard-to-reach populations.

  1. Effective number of breeders, effective population size and their relationship with census size in an iteroparous species, Salvelinus fontinalis.

    The relationship between the effective number of breeders (Nb) and the generational effective size (Ne) has rarely been examined empirically in species with overlapping generations and iteroparity. Based on a suite of 11 microsatellite markers, we examine the relationship between Nb, Ne and census population size (Nc) in 14 brook trout (Salvelinus fontinalis) populations inhabiting 12 small streams in Nova Scotia and sampled at least twice between 2009 and 2015. Unbiased estimates of Nb obtained with individuals of a single cohort, adjusted on the basis of age at first maturation (α) and adult lifespan (AL), were from 1.66 to 0.24 times the average estimates of Ne obtained with random samples of individuals of mixed ages (i.e. [Formula: see text]). In turn, these differences led to adjusted Ne estimates that were from nearly five to 0.7 times the estimates derived from mixed-aged individuals. These differences translate into the same range of variation in the ratio of effective to census population size [Formula: see text] within populations. Adopting [Formula: see text] as the more precise and unbiased estimates, we found that these brook trout populations differ markedly in their effective to census population sizes (range approx. 0.3 to approx. 0.01). Using AgeNe, we then showed that the variance in reproductive success or reproductive skew varied among populations by a factor of 40, from Vk/k ≈ 5 to 200. These results suggest wide differences in population dynamics, probably resulting from differences in productivity affecting the intensity of competition for access to mates or redds, and thus reproductive skew. Understanding the relationship between Ne, Nb and Nc, and how these relate to population dynamics and fluctuations in population size, are important for the design of robust conservation strategies in small populations with overlapping generations and iteroparity.

    The 10th Population Census Conference (April 29-May 3, 1985), in Honolulu, Hawaii, featured sessions on computers, fertility and mortality estimation, population projections, and mid-decade censuses and surveys. Senior officials from 15 national statistical offices attended sessions on computers in data analysis, integrated microcomputer systems and workstations of the future, and heard presentations on automation plans for the 1990 US census and New Zealand's Department of Statistics' census operation. 5 fertility and mortality estimation papers discussed own-children fertility estimates for Japan, Korea, and Pakistan, parity progression ratios use in estimating total fertility rates, and results from the 1981 Indian census. Population projection reports included presentations on 1) number and characteristics of Thailand's households, 2) Hong Kong projections based on period fertility rates, 3) computer-assisted Sri Lanka projections for 1981-2001, 4) Philippine population projections, 5) cohort-component projections for Australia, 6) Malaysia projections for 1985-2000, and 7) 1981 census based population projections in Bangladesh. Special country-specific studies included papers on 1) the 1983 Korean National Migration Survey, 2) Indonesian migration, 3) Indian immigrants in the US, 4) China's 1982 census, 5) Malaysia's census publications and demographic studies, and 6) the Bangladesh Bureau of Statistics' census and survey programs. A discussion on the 1980 World Census Program, which had as its goal the quality improvement of worldwide data, led into a discussion on the activities of the US Census Bureau's International Statistical Programs Center (ISPC) for the 1990 census. The conference included a demonstration of an integrated census data processing system recently developed at ISPC, and concluded with a session on mid-decade censuses and surveys. PMID:12267276

  4. A census of membrane-bound and intracellular signal transduction proteins in bacteria: Bacterial IQ, extroverts and introverts

    Directory of Open Access Journals (Sweden)

    Galperin Michael Y

    2005-06-01

    Full Text Available Abstract Background Analysis of complete microbial genomes showed that intracellular parasites and other microorganisms that inhabit stable ecological niches encode relatively primitive signaling systems, whereas environmental microorganisms typically have sophisticated systems of environmental sensing and signal transduction. Results This paper presents results of a comprehensive census of signal transduction proteins – histidine kinases, methyl-accepting chemotaxis receptors, Ser/Thr/Tyr protein kinases, adenylate and diguanylate cyclases and c-di-GMP phosphodiesterases – encoded in 167 bacterial and archaeal genomes, sequenced by the end of 2004. The data have been manually checked to avoid false-negative and false-positive hits that commonly arise during large-scale automated analyses and compared against other available resources. The census data show uneven distribution of most signaling proteins among bacterial and archaeal phyla. The total number of signal transduction proteins grows approximately as a square of genome size. While histidine kinases are found in representatives of all phyla and are distributed according to the power law, other signal transducers are abundant in certain phylogenetic groups but virtually absent in others. Conclusion The complexity of signaling systems differs even among closely related organisms. Still, it usually can be correlated with the phylogenetic position of the organism, its lifestyle, and typical environmental challenges it encounters. The number of encoded signal transducers (or their fraction in the total protein set can be used as a measure of the organism's ability to adapt to diverse conditions, the 'bacterial IQ', while the ratio of transmembrane receptors to intracellular sensors can be used to define whether the organism is an 'extrovert', actively sensing the environmental parameters, or an 'introvert', more concerned about its internal homeostasis. Some of the microorganisms with the

    Full Text Available Agriculture is a sector of the national economy which may represent a significant contribution to the economic growth if it is quantified properly. In Romania agriculture has declined significantly caused by various reasons. In frame of this study, we will attempt to discern their influence using official statistics. We will try to identify the place and the role of agriculture in Romania's actual economy from the perspective of GDP, investment in agriculture, the employment of this sector activity, because romanian agriculture remains an important sector in terms of view of agricultural area used, the contribution to GDP and, in particular, the percentage of the population employed.

    2016-04-01

    Full Text Available This study investigates the determinants of agricultural output in Syria, 1980-2010. The Johansen cointegration test results indicate that agricultural outputs are positively related to the capital, food exports, expenditure and arable land, and negatively related to the oil price. Arable land has the biggest effect on agricultural outputs. The Granger causality test indicates bidirectional short-run causality relationships between capital, food exports, expenditure, arable land and agricultural outputs, and unidirectional short-run causality relationship running from oil price to agricultural outputs. There are also unidirectional long-run causality relationships moving from agricultural outputs to gross fixed capital formation of agriculture, oil price, food exports and arable land. However, there is no long-run causality relationships between final consumption expenditure and agricultural outputs. The result indicates that it is important to speed up the land reclamation process and encourage the investment in the agricultural sector.

    Contextual research on time and place requires a consistent measurement instrument for neighborhood conditions in order to make unbiased inferences about neighborhood change. We develop such a time-invariant measure of neighborhood socio-economic status (NSES) using exploratory and confirmatory factor analyses fit to census data at the tract level from the 1990 and 2000 U.S. Censuses and the 2008-2012 American Community Survey. A single factor model fit the data well at all three time periods, and factor loadings-but not indicator intercepts-could be constrained to equality over time without decrement to fit. After addressing remaining longitudinal measurement bias, we found that NSES increased from 1990 to 2000, and then-consistent with the timing of the "Great Recession"-declined in 2008-2012 to a level approaching that of 1990. Our approach for evaluating and adjusting for time-invariance is not only instructive for studies of NSES but also more generally for longitudinal studies in which the variable of interest is a latent construct.

    Before the eighteenth century, there was limited response to the problem of psychiatric illness in Ireland as in many other countries. The asylums of the 1820s and 1830s were no sooner opened than they were overcrowded. A second wave of asylum building commenced in the second half of the nineteenth century continuing up to the early twentieth century. In 1966, the Report of the Commission on Mental Illness noted that the rate of psychiatric beds in Ireland per 1,000 was one of the highest in the world. The report called for a change in the policy of caring for the mentally ill in psychiatric hospitals to more community-based settings and in psychiatric units located in general hospital settings, along with a call for more research into mental illness. The result of the latter was the establishment of the first census of psychiatric patients resident in psychiatric hospitals. Thus began fifty years of census reporting and the subsequent establishment of the National Psychiatric Inpatient Reporting System (NPIRS). PMID:26667467

    A number of demographic factors, many of which related to human-driven encroachments, are predicted to decrease the effective population size (N(e)) relative to the census population size (N), but these have been little investigated. Yet, it is necessary to know which factors most strongly impact N(e), and how to mitigate these effects through sound management actions. In this study, we use parentage analysis of a stream-living brown trout (Salmo trutta) population to quantify the effect of between-individual variance in reproductive success on the effective number of breeders (N(b)) relative to the census number of breeders (N(i)). Comprehensive estimates of the N(b)/N ratio were reduced to 0.16-0.28, almost entirely due to larger than binomial variance in family size. We used computer simulations, based on empirical estimates of age-specific survival and fecundity rates, to assess the effect of repeat spawning (iteroparity) on N(e) and found that the variance in lifetime reproductive success was substantially higher for repeat spawners. Random family-specific survival, on the other hand, acts to buffer these effects. We discuss the implications of these findings for the management of small populations, where maintaining high and stable levels of N(e) is crucial to extenuate inbreeding and protect genetic variability.

There are a lot of factors to cause such result, among which, the main ones are the unbalancing relationship between censuses, census and periodical reporting questionnaire. The authors also raise several suggestions of policy deciding.

  19. TPA: A Two-Phase Approach Using Simulated Annealing for the Optimization of Census Taker Routes in Mexico

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Censuses in Mexico are taken by the National Institute of Statistics and Geography (INEGI. In this paper a Two-Phase Approach (TPA to optimize the routes of INEGI’s census takers is presented. For each pollster, in the first phase, a route is produced by means of the Simulated Annealing (SA heuristic, which attempts to minimize the travel distance subject to particular constraints. Whenever the route is unrealizable, it is made realizable in the second phase by constructing a visibility graph for each obstacle and applying Dijkstra’s algorithm to determine the shortest path in this graph. A tuning methodology based on the irace package was used to determine the parameter values for TPA on a subset of 150 instances provided by INEGI. The practical effectiveness of TPA was assessed on another subset of 1962 instances, comparing its performance with that of the in-use heuristic (INEGIH. The results show that TPA clearly outperforms INEGIH. The average improvement is of 47.11%.

    We compile the first comprehensive census of hot luminous stars in the 30 Doradus (30 Dor) star forming region of the LMC. The census extends to a radius of 10arcmin (150pc) from the central cluster, R136. Stars were selected photometrically and combined with the latest spectral types. 1145 candidate hot luminous stars were identified of which >700 were considered genuine early type stars that contribute to feedback. We assess the spectroscopic completeness to be 85% in outer regions (>5pc) but fall to 35% in the vicinity of R136, giving a total of 500 hot luminous stars with spectroscopy. Stellar calibrations and models were used to obtain their physical parameters before integrated values were compared to global observations and the population synthesis code, Starburst99. The 31 W-R and Of/WN stars made large contributions to the total ionising and wind luminosities of ~40% and ~50%, respectively. Stars with Minit>100Msun also showed high contributions to the global feedback, ~25% in both cases. Such massiv...

  4. Remote sensing and GIS in support of sustainable agricultural development

    Science.gov (United States)

    Duro, Dennis Correa

    Over the coming decades it is expected that the vast amounts of area currently in agricultural production will face growing pressure to intensify as world populations continue to grow, and the demand for a more Western-based diet increases. Coupled with the potential consequences of climate change, and the increasing costs involved with current energy-intensive agricultural production methods, meeting goals of environmental and socioeconomic sustainability will become ever more challenging. At a minimum, meeting such goals will require a greater understanding of rates of change, both over time and space, to properly assess how present demand may affect the needs of future generations. As agriculture represents a fundamental component of modern society, and the most ubiquitous form of human induced landscape change on the planet, it follows that mapping and tracking changes in such environments represents a crucial first step towards meeting the goal of sustainability. In anticipation of the mounting need for consistent and timely information related to agricultural development, this thesis proposes several advances in the field of geomatics, with specific contributions in the areas of remote sensing and spatial analysis: First, the relative strengths of several supervised machine learning algorithms used to classify remotely sensed imagery were assessed using two image analysis approaches: pixel-based and object-based. Second, a feature selection process, based on a Random Forest classifier, was applied to a large data set to reduce the overall number of object-based predictor variables used by a classification model without sacrificing overall classification accuracy. Third, a hybrid object-based change detection method was introduced with the ability to handle disparate image sources, generate per-class change thresholds, and minimize map updating errors. Fourth, a spatial disaggregation procedure was performed on coarse scale agricultural census data to render

  6. A spatial analysis of patterns of growth and concentration of population based on homogeneous population censuses: Spain (1877-2001

    Directory of Open Access Journals (Sweden)

    Xavier Franch Auladell

    2013-01-01

    Full Text Available This work constitutes a contribution to the analysis of long term patterns of population concentration applied to the case of Spain. The proposed methodology is based on the homogenisation of both data and administrative units which takes the municipal structure of the 2001 census as its base reference. This work seeks to show how applying spatial analysis techniques to this type of homogeneous data series allows us to make more detailed studies of population patterns within a given territory. The most important conclusions that we reached was that, in Spain, sustained population growth has followed a spatial pattern that has become increasingly consolidated over time. The tendencies observed have produced an uneven distribution of population within the national territory marked by the existence of a series of well-defined, and often very localised, areas that spread beyond the limits of the official administrative boundaries.

    Full Text Available Abstract Background Imbalance in the distribution of human resources for health (HRH, eventually leading to inequities in health services delivery and population health outcomes, is an issue of social and political concern in many countries. However, the empirical evidence to support decision-making is often fragmented, and many standard data sources that can potentially produce statistics relevant to the issue remain underused, especially in developing countries. This study investigated the uses of demographic census data for monitoring geographical imbalance in the health workforce for three developing countries, as a basis for formulation of evidence-based health policy options. Methods Population-based indicators of geographical variations among HRH were extracted from census microdata samples for Kenya, Mexico and Viet Nam. Health workforce statistics were matched against international standards of occupational classification to control for cross-national comparability. Summary measures of inequality were calculated to monitor the distribution of health workers across spatial units and by occupational group. Results Strong inequalities were found in the geographical distribution of the health workforce in all three countries, with the highest densities of HRH tending to be found in the capital areas. Cross-national differences were found in the magnitude of distributional inequality according to occupational group, with health professionals most susceptible to inequitable distribution in Kenya and Viet Nam but less so in Mexico compared to their associate professional counterparts. Some discrepancies were suggested between mappings of occupational information from the raw data with the international system, especially for nursing and midwifery specializations. Conclusions The problem of geographical imbalance among HRH across countries in the developing world holds important implications at the local, national and international levels, in

  15. Do measures matter? Comparing surface-density-derived and census-tract-derived measures of racial residential segregation

    Full Text Available Abstract Background Racial residential segregation is hypothesized to affect population health by systematically patterning health-relevant exposures and opportunities according to individuals' race or income. Growing interest into the association between residential segregation and health disparities demands more rigorous appraisal of commonly used measures of segregation. Most current studies rely on census tracts as approximations of the local residential environment when calculating segregation indices of either neighborhoods or metropolitan areas. Because census tracts are arbitrary in size and shape, reliance on this geographic scale limits understanding of place-health associations. More flexible, explicitly spatial derivations of traditional segregation indices have been proposed but have not been compared with tract-derived measures in the context of health disparities studies common to social epidemiology, health demography, or medical geography. We compared segregation measured with tract-derived as well as GIS surface-density-derived indices. Measures were compared by region and population size, and segregation measures were linked to birth record to estimate the difference in association between segregation and very preterm birth. Separate analyses focus on metropolitan segregation and on neighborhood segregation. Results Across 231 metropolitan areas, tract-derived and surface-density-derived segregation measures are highly correlated. However overall correlation obscures important differences by region and metropolitan size. In general the discrepancy between measure types is greatest for small metropolitan areas, declining with increasing population size. Discrepancies in measures are greatest in the South, and smallest in Western metropolitan areas. Choice of segregation index changed the magnitude of the measured association between segregation and very preterm birth. For example among black women, the risk ratio for very

    Access to the college cycle for students with disabilities and their employability have become a priority for universities. The Handicap Mission manages it within the Aix-Marseille University (AMU). Few studies have focused on the students with disabilities' insertion/integration within the universities and on the compensations. The objective of this study is to analyze within the AMU the students with disabilities census and characteristics, and the Handicap Mission's operating. The census was conducted using a self-administered questionnaire (Handi need card: university curriculum, deficiencies, technical and social help, adjustments appealed for at the university). It was performed by the staff at the AMU's Mission Handicap Department/Office. If supporting measures seem to be necessary, the interdisciplinary team (comprised of representatives of the University teaching, Administrative and Technical staff, Mission Handicap staff, Preventive Medicine staff, and partners from associations involved in assisting people with disabilities) then defines and sets up suitable means of assistance. The Handicap Mission improves students with disabilities insertion, defines necessary adjustments, and promotes research on disability. A total of 551 students with disabilities were identified, 304 in law and human sciences. In all, 141 deficiencies encountered related to language disorders, among which 105 were not defined by the students ('Other' in the questionnaire). In all, 519 SWD benefited from extra time when sitting exams and 40 were helped to take notes by others students. Compensations and Handicap Mission improve the monitoring and the link between high school and university for the students with disabilities, promote their exam success, and support them in their working life.

    Full Text Available The purpose of this paper is to introduce a modification of a standardfour input production process where energy is used in an inefficient way due topartly unnecessary waste of energy. The changes in production efficiencyinvestigated using stochastic frontier methods, show declining technicalefficiency in livestock production and especially low marginal contribution oflabor inputs. The number of workers, size of farm, and distance from nearestcity are related to efficiency in agricultural production. It is well known thatresults from an environmental policy in response to global climate change arequite sensitive to the assumption on the rate of energy efficiency improvements.However, technical progress is traditionally considered as a non-economicvariable in economic policy models. It is exogenous in most policy evaluationsas well as in the theory of environmental economics.

    Context. The VLT-FLAMES Tarantula Survey has an extensive view of the copious number of massive stars in the 30 Doradus (30 Dor) star forming region of the Large Magellanic Cloud. These stars play a crucial role in our understanding of the stellar feedback in more distant, unresolved star forming regions. Aims: The first comprehensive census of hot luminous stars in 30 Dor is compiled within a 10 arcmin (150 pc) radius of its central cluster, R136. We investigate the stellar content and spectroscopic completeness of the early type stars. Estimates were made for both the integrated ionising luminosity and stellar wind luminosity. These values were used to re-assess the star formation rate (SFR) of the region and determine the ionising photon escape fraction. Methods: Stars were selected photometrically and combined with the latest spectral classifications. Spectral types were estimated for stars lacking spectroscopy and corrections were made for binary systems, where possible. Stellar calibrations were applied to obtain their physical parameters and wind properties. Their integrated properties were then compared to global observations from ultraviolet (UV) to far-infrared (FIR) imaging as well as the population synthesis code, Starburst99. Results: Our census identified 1145 candidate hot luminous stars within 150 pc of R136 of which >700 were considered to be genuine early type stars and contribute to feedback. We assess the survey to be spectroscopically complete to 85% in the outer regions (>5 pc) but only 35% complete in the region of the R136 cluster, giving a total of 500 hot luminous stars in the census which had spectroscopy. Only 31 were found to be Wolf-Rayet (W-R) or Of/WN stars, but their contribution to the integrated ionising luminosity and wind luminosity was ~40% and ~50%, respectively. Similarly, stars with Minit > 100 M⊙ (mostly H-rich WN stars) also showed high contributions to the global feedback, ~25% in both cases. Such massive stars are not
