Full Text Available Il presente studio analizza Velvet Goldmine un film del 1998 diretto da Todd Haynes al fine di indagare come il regista americano riesca ad evidenziare la centralità del glam (emerso in Gran Bretagna nei primi anni Settanta nella cultura contemporanea, ponendo un' enfasi specifica sull’aspetto che più di ogni altro aveva caratterizzato quell’esperienza, ossia la sovversione parodica dell' idea di mascolinità normativa nei decenni precedenti. Sul palco i 'glamsters' – ossia artisti quali Bolan, Bowie, Roxy Music, Glitter – erano in grado, utilizzando segni visivi quali trucco e abiti 'glitter' di costruire un’identità di genere ibrida che si poneva in netto contrasto con il machismo di molti musicisti degli anni Sessanta. Seguendo un approccio metodologico in cui studi culturali, studi letterari e neo-musicologia finiscono per dialogare tra loro, la presente indagine crea uno stretto rapporto tra Oscar Wilde e la cultura glam – un rapporto individuato dal regista sin dalle prime battute del film – ma che qui viene declinato in un senso più specifico, in base al quale l' intero film rappresenta una parodia o reinvenzione glam dell'intera epopea wildiana e in cui le immagini e gli aforismi wildiani sembrano interrogare con la loro complessità e la loro portata dissacrante il nostro presente. The present essay analyses Velvet Goldmine a 1998 film directed by Todd Haynes, in order to investigate how the American director points to the relevance of glam (emerged in Great Britain at the beginning of the Seventies within contemporary culture, focusing on one of its most relevant aspects, that is the parodic subversion of the normative idea of masculinity which was dominant in the previous decades. Glamsters – that is, such artists as Bolan, Bowie, Roxy Music and Glitter – were able, using such visual signs as make-up and glitter dresses, to construct a hybrid gender identity, which sharply contrasted with the normative

The Mediterranean Basin (MB) is at the crossroad of pollutant emissions from Western and Central Europe and of major dust sources from Sahara and Arabian deserts and thus sensitive to climate change and air quality. Several studies (Formenti et al.,J. Geophys. Res., 2002; Ancellet et al., Atmos. Chem. Phys., 2016) also show the impact on the MB of long-range transport of polluted air masses. However, most of the studies have been dedicated to biomass burning aerosols. The aim of the present study is to show trace gases impact on the MB coming from long-range transport of biomass burning. The Gradient in Longitude of Atmospheric constituents above the Mediterranean basin (GLAM) campaign in August 2014, as part of the Chemistry-Aerosol Mediterranean Experiment (ChArMEx) project, aimed at studying the tropospheric chemical variability of gaseous pollutants and aerosols along a West-East transect above the MB. During the GLAM campaign, several instruments onboard the Falcon-20 aircraft (SAFIRE, INSU / Météo-France) were deployed including an infrared laser spectrometer (SPIRIT, LPC2E) able to detect weak variations in the concentration of pollutants. During two flights on 6 and 10 August, increases in CO, O3 and aerosols were measured over Sardinia at 5000 and 9000 m asl, respectively. To assess the origin of the air masses, 20-day backward trajectories with a nested-grid regional scale Lagrangian particle dispersion model (FLEXPART, Stohl et al., Atmos. Chem. Phys., 2005) were calculated. Combined with emissions coming from the Global Fire Assimilation System (GFAS) inventory (Kaiser et al., Biogeosciences, 2012), this leads to CO biomass burning contribution to aircraft measured values. Biomass burning emissions located in Siberia in the first case and in northern America in the second case were identified as the cause of this burden of pollutants in the mid and upper troposphere over the MB. By adjusting the injection height of the model and amplifying emissions

Human brain accounts for about one hundred billion neurons, but they cannot work properly without ultrastructural and metabolic support. For this reason, mammalian brains host another type of cells called “glial cells”, whose role is to maintain proper conditions for efficient neuronal function. One type of glial cell, astrocytes, are involved in particular in the metabolic support of neurons, by feeding them with lactate, one byproduct of glucose metabolism that they can take up from blood vessels, and store it under another form, glycogen granules. These energy-storage molecules, whose morphology resembles to spheres with a diameter ranging 10–80 nanometers roughly, can be easily recognized using electron microscopy, the only technique whose resolution is high enough to resolve them. Understanding and quantifying their distribution is of particular relevance for neuroscientists, in order to understand where and when neurons use energy under this form. To answer this question, we developed a visualization technique, dubbed GLAM (Glycogen-derived Lactate Absorption Map), and customized for the analysis of the interaction of astrocytic glycogen on surrounding neurites in order to formulate hypotheses on the energy absorption mechanisms. The method integrates high-resolution surface reconstruction of neurites, astrocytes, and the energy sources in form of glycogen granules from different automated serial electron microscopy methods, like focused ion beam scanning electron microscopy (FIB-SEM) or serial block face electron microscopy (SBEM), together with an absorption map computed as a radiance transfer mechanism. The resulting visual representation provides an immediate and comprehensible illustration of the areas in which the probability of lactate shuttling is higher. The computed dataset can be then explored and quantified in a 3D space, either using 3D modeling software or virtual reality environments. Domain scientists have evaluated the technique by

The Gradient in Longitude of Atmospheric constituents above the Mediterranean basin (GLAM) campaign was set up in August 2014, as part of the Chemistry and Aerosol Mediterranean Experiment (ChArMEx) project. This campaign aimed to study the chemical variability of gaseous pollutants and aerosols in the troposphere along a west-east transect above the Mediterranean Basin (MB). In the present work, we focus on two biomass burning events detected at 5.4 and 9.7 km altitude above sea level (a.s.l.) over Sardinia (from 39°12' N-9°15' E to 35°35' N-12°35' E and at 39°30' N-8°25' E, respectively). Concentration variations in trace gas carbon monoxide (CO), ozone (O3) and aerosols were measured thanks to the standard instruments on board the Falcon 20 aircraft operated by the Service des Avions Français Instrumentés pour la Recherche en Environnement (SAFIRE) and the Spectromètre InfraRouge In situ Toute Altitude (SPIRIT) developed by LPC2E. Twenty-day backward trajectories with Lagrangian particle dispersion model FLEXPART (FLEXible PARTicle) help to understand the transport processes and the origin of the emissions that contributed to this pollution detected above Sardinia. Biomass burning emissions came (i) on 10 August from the North American continent with air masses transported during 5 days before arriving over the MB, and (ii) on 6 August from Siberia, with air masses travelling during 12 days and enriched in fire emission products above Canada 5 days before arriving over the MB. In combination with the Global Fire Assimilation System (GFAS) inventory and the Moderate Resolution Imaging Spectroradiometer (MODIS) satellite fire locations, FLEXPART reproduces well the contribution of those fires to CO and aerosols enhancements under adjustments of the injection height to 10 km in both cases and application of an amplification factor of 2 on CO GFAS emissions for the 10 August event.

In weak gravitational lensing, weighted quadrupole moments of the brightness profile in galaxy images are a common way to estimate gravitational shear. We have employed general adaptive moments (GLAM ) to study causes of shear bias on a fundamental level and for a practical definition of an image ellipticity. The GLAM ellipticity has useful properties for any chosen weight profile: the weighted ellipticity is identical to that of isophotes of elliptical images, and in absence of noise and pixellation it is always an unbiased estimator of reduced shear. We show that moment-based techniques, adaptive or unweighted, are similar to a model-based approach in the sense that they can be seen as imperfect fit of an elliptical profile to the image. Due to residuals in the fit, moment-based estimates of ellipticities are prone to underfitting bias when inferred from observed images. The estimation is fundamentally limited mainly by pixellation which destroys information on the original, pre-seeing image. We give an optimised estimator for the pre-seeing GLAM ellipticity and quantify its bias for noise-free images. To deal with images where pixel noise is prominent, we consider a Bayesian approach to infer GLAM ellipticity where, similar to the noise-free case, the ellipticity posterior can be inconsistent with the true ellipticity if we do not properly account for our ignorance about fit residuals. This underfitting bias, quantified in the paper, does not vary with the overall noise level but changes with the pre-seeing brightness profile and the correlation or heterogeneity of pixel noise over the image. Furthermore, when inferring a constant ellipticity or, more relevantly, constant shear from a source sample with a distribution of intrinsic properties (sizes, centroid positions, intrinsic shapes), an additional, now noise-dependent bias arises towards low signal-to-noise if incorrect prior densities for the intrinsic properties are used. We discuss the origin of this

Linking Fine-Scale Observations and Model Output with Imagery at Multiple Scales
Sadler, J.; Walthall, C. L.
2014-12-01
The development and implementation of a system for seasonal worldwide agricultural yield estimates is underway with the international Group on Earth Observations GeoGLAM project. GeoGLAM includes a research component to continually improve and validate its algorithms. There is a history of field measurement campaigns going back decades to draw upon for ways of linking surface measurements and model results with satellite observations. Ground-based, in-situ measurements collected by interdisciplinary teams include yields, model inputs and factors affecting scene radiation. Data that is comparable across space and time with careful attention to calibration is essential for the development and validation of agricultural applications of remote sensing. Data management to ensure stewardship, availability and accessibility of the data are best accomplished when considered an integral part of the research. The expense and logistical challenges of field measurement campaigns can be cost-prohibitive and because of short funding cycles for research, access to consistent, stable study sites can be lost. The use of a dedicated staff for baseline data needed by multiple investigators, and conducting measurement campaigns using existing measurement networks such as the USDA Long Term Agroecosystem Research network can fulfill these needs and ensure long-term access to study sites.

Satellite Monitoring for Early Warning and Triggering Disaster Risk Financing in Uganda
Nakalembe, C. L.; Owor, M.
2016-12-01
Natural disasters typically occur with little warning and can have grave and long-lasting negative consequences especially for populations fully dependent on rainfed agriculture. Disaster risk financing (DRF) aims to scale up alternative livelihoods such as Labour Intensive Public Works (LIPW) when a disaster hits to minimize the likely impacts on communities. In data-rich regions triggering DRF or crop insurances payouts can be easily implemented e.g in the case of agriculture, yield losses due to drought can be measured directly. This is constrained in Uganda, because seasonal/annual production data are scarce due to the subsistence and smallholder nature of agriculture in addition to low capacity for data collection and analysis in the country. Satellite remote sensing based indices, in particular the Normalized Difference Vegetation Index (NDVI), provides an objective and dependable solution to this challenge. Using MODIS satellite imagery provided through the GLAM East-Africa portal (Global Agricultural Monitoring system adapted for East-Africa) for obtaining NDVI time-series in near real-time, the Office of the Prime Minister of Uganda (OPM) is designing an operational crop conditions monitoring system in support of its recently initiated DRF Project, under the Third Northern Uganda Social Action Fund (NUSAF 2). The basis for triggering the DRF mechanism under this project is the deviation from the long-term NDVI (NDVI Anomaly data) within the growing season beyond a defined threshold. The NDVI data that are preprocessed in the GLAM system offer spatially explicit information on vegetation and crop conditions forming an adequate base for assessing generalized growing season conditions and enabling the quick implementation of DRF using transparent and objective criteria. The system and criteria serve also as an early-warning mechanism as the NDVI anomaly approaches the triggering threshold allowing time for planning and implementing LIPW projects.

Rain-fed agriculture is of utmost importance in sub-Saharan Africa; the FAO estimates that over 90% of food consumed in the region is grown in rain-fed farming systems. As the climate in sub-Saharan Africa has a high interannual variability, this dependence on rainfall can leave communities extremely vulnerable to food shortages, especially when coupled with a lack of crop management options. The ability to make a regional forecast of crop yield on a timescale of months would be of enormous benefit; it would enable both governmental and non-governmental organisations to be alerted in advance to crop failure and could facilitate national and regional economic planning. Such a system would also enable individual communities to make more informed crop management decisions, increasing their resilience to climate variability and change. It should be noted that the majority of crops in the region are rainfall limited, therefore the ability to create a seasonal crop forecast depends on the ability to forecast rainfall at a monthly or seasonal timescale and to temporally downscale this to a daily time-series of rainfall. The aim of this project is to develop a regional-scale seasonal forecast for sub-Saharan crops, utilising the General Large Area Model for annual crops (GLAM). GLAM would initially be driven using both dynamical and statistical seasonal rainfall forecasts to provide an initial estimate of crop yield. The system would then be continuously updated throughout the season by replacing the seasonal rainfall forecast with daily weather observations. TAMSAT satellite rainfall estimates are used rather than rain-gauge data due to the scarcity of ground based observations. An important feature of the system is the use of the geo-statistical method of sequential simulation to create an ensemble of daily weather inputs from both the statistical seasonal rainfall forecasts and the satellite rainfall estimates. This allows a range of possible yield outputs to be

Full Text Available Wikipedia edit-a-thons represent a unique and fruitful avenue for galleries, libraries, archives and museums (GLAMs to engage with new and existing segments of their user communities. Encompassing information and technical literacy skills development, the success of edit-a-thon campaigns, such the annual art+feminism events, demonstrate their utility and value as outreach initiatives. What is less clear are the logistical, ethical and professional development implications of hosting these events. Centering first-hand experience and concrete examples, this paper explores GLAM-based edit-a-thons through a practical and actionable lens. Topics covered include: what is required to successfully host an edit-a-thon; the importance of leading by example in a volunteer-reliant economy; and the transferable work skills gained by hosting and participating in edit-a-thons. Des « édit-a-thons » (marathon d’édition de texte sur Wikipédia offrent aux galeries, bibliothèques, archives et musées une façon unique et efficace d’interagir avec de nouveaux ou d’existants segments de leur communauté.

Support Science by Publishing in Scientific Society Journals.
Schloss, Patrick D; Johnston, Mark; Casadevall, Arturo
2017-09-26
Scientific societies provide numerous services to the scientific enterprise, including convening meetings, publishing journals, developing scientific programs, advocating for science, promoting education, providing cohesion and direction for the discipline, and more. For most scientific societies, publishing provides revenues that support these important activities. In recent decades, the proportion of papers on microbiology published in scientific society journals has declined. This is largely due to two competing pressures: authors' drive to publish in "glam journals"-those with high journal impact factors-and the availability of "mega journals," which offer speedy publication of articles regardless of their potential impact. The decline in submissions to scientific society journals and the lack of enthusiasm on the part of many scientists to publish in them should be matters of serious concern to all scientists because they impact the service that scientific societies can provide to their members and to science.

Disability and handicap among elderly Singaporeans.
Yadav, S S
2001-08-01
Singapore's elderly population has been growing rapidly and is expected to constitute more than 25 percent of the total population by the year 2030. The ageing process brings with it a host of health problems. Here the question arises--Are the increasing years of life going to create a high proportion of sick and disabled elderly people, or a rich human resource of healthy senior citizens? Since more women are living longer than men, who would face a higher risk of disability and handicap? These questions are yet to be answered in Singapore. This paper seeks answers to these questions. The study is based on a sample survey of 1209 elderly Singaporeans living in Kampong Glam, Kreta Ayer and Bukit Merah parliamentary constituencies which have some of the highest proportions of the aged population. The results revealed that more than half of the aged had a disability and the rate of disability was significantly higher among the women as compared to the men. More than one-third of the elderly had a handicap and the rate of handicap among the women was twice as much as that among the men. Severity of handicap was directly correlated with age.

Full Text Available The “E.R. Caianiello” Central Library of the University of Salerno preserves many private bibliographic collections. This paper focuses on their valorization through an integrated approach encompassing dissemination, social media communication and research. The dissemination was developed as part of the collaboration to the Wikimedia projects. In particular we created a GLAM working group that enriched Wikipedia, Wikidata and Commons with contents and data related to the private collections. As for the communication, after drafting an editorial plan and a social media policy, the social media profiles of the library were used to provide information to the general public about the collections, including the bibliographic description and a link to the biographic article on Wikipedia, using a dedicated hashtag #fondispeciali. The research path included the organization of the conference “Biblioteca di biblioteche”, held on May 26, 2016 and supported by AIB Campania and Wikimedia Italia, which inaugurated a bio-bibliographic exhibition dedicated to the Cilento, Cuomo, Grottanelli and Paparelli collections. The valorization process generated a positive impact in many areas including the production of new referenced contents, the creation of collaborative networks with other cultural institutions and the continuous training of librarians involved in the projects.

“Having it All” on Social Media: Entrepreneurial Femininity and Self-Branding Among Fashion Bloggers
Directory of Open Access Journals (Sweden)
Brooke Erin Duffy
2015-09-01
Full Text Available Against the backdrop of the widespread individualization of the creative workforce, various genres of social media production have emerged from the traditionally feminine domains of fashion, beauty, domesticity, and craft. Fashion blogging, in particular, is considered one of the most commercially successful and publicly visible forms of digital cultural production. To explore how fashion bloggers represent their branded personae as enterprising feminine subjects, we conducted a qualitative analysis of the textual ( n = 38 author narratives and visual ( n = 760 Instagram images content published by leading fashion bloggers; we supplement this with in-depth interviews with eight full-time fashion/beauty bloggers. Through this data, we show how top-ranked bloggers depict the ideal of “having it all” through three interrelated tropes: the destiny of passionate work, staging the glam life, and carefully curated social sharing. Together, these tropes articulate a form of entrepreneurial femininity that draws upon post-feminist sensibilities and the contemporary logic of self-branding. We argue, however, that this socially mediated version of self-enterprise obscures the labor, discipline, and capital necessary to emulate these standards, while deploying the unshakable myth that women should work through and for consumption. We conclude by addressing how these findings are symptomatic of a digital media economy marked by the persistence of social inequalities of gender, race, class, and more.

Selfies of Ill Health: Online Autopathographic Photography and the Dramaturgy of the Everyday
Directory of Open Access Journals (Sweden)
Tamar Tembeck
2016-03-01
Full Text Available This article offers a preliminary investigation into what I term “selfies of ill health” and traces the expansion of the autopathographic genre in visual media from professional art photography to the vernacular selfie in recent years. In this context, the word autopathography is used to describe self-representational practices that offer a first-person perspective on experiences of illness or hospitalization. I first situate the genre by identifying several typologies of selfies of ill health, including diagnostic selfies, cautionary selfies, and treatment impact selfies. I then focus on the forms of identity performance that selfies, and selfies of ill health in particular, deploy. I argue that the performative qualities of certain selfies of ill health overlap with salient characteristics of autopathographic practice in the arts. Using Karolyn Gehrig’s #HospitalGlam series as a case study, I examine how autopathographic selfies can also construct a politicized dramaturgy of the lived body, notably by enabling individuals like Gehrig to “come out” as being invisibly ill. I conclude that the dramaturgical thrust of such autopathographic imagery is to convey both the centrality of medical experiences in subjects’ lives and their specific desire to be publicly identified as persons living with illness. In light of this, although selfies of ill health may have opened up new avenues for autopathographic practice thanks to the affordances of social media, their communicative intents remain consistent with those of earlier forms of autopathographic photography.

Friction behavior of ceramic injection-molded (CIM) brackets.
Reimann, Susanne; Bourauel, Christoph; Weber, Anna; Dirk, Cornelius; Lietz, Thomas
2016-07-01
Bracket material, bracket design, archwire material, and ligature type are critical modifiers of friction behavior during archwire-guided movement of teeth. We designed this in vitro study to compare the friction losses of ceramic injection-molded (CIM) versus pressed-ceramic (PC) and metal injection-molded (MIM) brackets-used with different ligatures and archwires-during archwire-guided retraction of a canine. Nine bracket systems were compared, including five CIM (Clarity™ and Clarity™ ADVANCED, both by 3M Unitek; discovery(®) pearl by Dentaurum; Glam by Forestadent; InVu by TP Orthodontics), two PC (Inspire Ice by Ormco; Mystique by DENTSPLY GAC), and two MIM (discovery(®) and discovery(®) smart, both by Dentaurum) systems. All of these were combined with archwires made of either stainless steel or fiberglass-reinforced resin (remanium(®) ideal arch or Translucent pearl ideal arch, both by Dentaurum) and with elastic ligatures or uncoated or coated stainless steel (all by Dentaurum). Archwire-guided retraction of a canine was simulated with a force of 0.5 N in the orthodontic measurement and simulation system (OMSS). Friction loss was determined by subtracting the effective orthodontic forces from the applied forces. Based on five repeated measurements performed on five brackets each, weighted means were calculated and evaluated by analysis of variance and a Bonferroni post hoc test with a significance level of 0.05. Friction losses were significantly (p brackets used with a stainless-steel ligature and the resin archwire. No critical difference to friction behavior was apparent between the various manufacturing technologies behind the bracket systems.

In-season monitoring of crop conditions provides critical information for agricultural policy and decision making and most importantly for food security planning and management. Nationwide agricultural monitoring in countries dominated by smallholder farming systems, generally relies on extensive networks of field data collectors. In Tanzania, extension agents make up this network and report on conditions across the country, approaching a "near-census". Data is collected on paper which is resource and time intensive, as well as prone to errors. Data quality is ambiguous and there is a general lack of clear and functional feedback loops between farmers, extension agents, analysts and decision makers. Moreover, the data are not spatially explicit, limiting the usefulness for analysis and quality of policy outcomes. Despite significant advances in remote sensing and information communication technologies (ICT) for monitoring agriculture, the full potential of these new tools is yet to be realized in Tanzania. Their use is constrained by the lack of resources, skills and infrastructure to access and process these data. The use of ICT technologies for data collection, processing and analysis is equally limited. The AgriSense-STARS project is developing and testing a system for national-scale in-season monitoring of smallholder agriculture using a combination of three main tools, 1) GLAM-East Africa, an automated MODIS satellite image processing system, 2) field data collection using GeoODK and unmanned aerial vehicles (UAVs), and 3) the Tanzania Crop Monitor, a collaborative online portal for data management and reporting. These tools are developed and applied in Tanzania through the National Food Security Division of the Ministry of Agriculture, Food Security and Cooperatives (MAFC) within a statistically representative sampling framework (area frame) that ensures data quality, representability and resource efficiency.

Global Food Security-support data at 30 m (GFSAD30)
Thenkabail, P. S.
2013-12-01
Monitoring global croplands (GCs) is imperative for ensuring sustainable water and food security to the people of the world in the Twenty-first Century. However, the currently available cropland products suffer from major limitations such as: (1) Absence of precise spatial location of the cropped areas; (b) Coarse resolution nature of the map products with significant uncertainties in areas, locations, and detail; (b) Uncertainties in differentiating irrigated areas from rainfed areas; (c) Absence of crop types and cropping intensities; and (e) Absence of a dedicated webdata portal for the dissemination of cropland products. Therefore, our project aims to close these gaps through a Global Food Security-support data at 30 m (GFSAD30) with 4 distinct products: 1. Cropland extentarea, 2. Crop types with focus on 8 crops that occupy 70% of the global cropland areas, 3. Irrigated versus rainfed, and 4. Cropping intensities: single, double, triple, and continuous cropping. The above 4 products will be generated for GFSAD for nominal year 2010 (GFSAD2010) based on Landsat 30m Global Land Survey 2010 (GLS2010) fused with Moderate Resolution Imaging Spectroradiometer (MODIS) 250m NDVI monthly maximum value composites (MVC) of 2009-2011 data, and suite of secondary data (e.g., long-term precipitation, temperature, GDEM elevation). GFSAD30 will be produced using three mature cropland mapping algorithms (CMAs): 1. Spectral matching techniques; 2. A cropland classification algorithm (ACCA) that is rule-based; and 3. Hierarchical segmentation (HSeg) algorithm. Funded by NASA MEaSUREs, GFSAD30 will make significant contributions to Earth System Data Records (ESDRs), Group on Earth Observations (GEO) Agriculture and Water Societal Beneficial Areas (GEO Ag. SBAs), GEO Global Agricultural Monitoring Initiative (GEO GLAM), and the recent 'Big Data' initiative by the White House. The project has the support of USGS Working Group on Global Croplands (https://powellcenter.usgs.gov/globalcroplandwater/).

Accurate and timely information on agriculture, particularly in many countries dominated by complex smallholder, subsistence agricultural systems is often difficult to obtain or not available. This includes up-to-date information during the growing season on crop type, crop area and crop condition such as developmental stage, damage from pests and diseases, drought or flooding. These data are critical for government decision making on production forecasts, planning for commodity market transactions, food aid delivery, responding to disease outbreaks and for implementing agricultural extension and development efforts. In Tanzania we have been working closely with the National Food Security Division (NFSD) at the Ministry of Agriculture, Livestock and Fisheries (MALF) on designing and implementing an advanced agricultural monitoring system, utilizing satellite remote sensing, smart phone and internet technologies. Together with our local implementing partner, the Sokoine University of Agriculture we trained a large number of agricultural extension agents in different regions of Tanzania to deliver field data in near-realtime. Using our collaborative internet portal (Crop Monitor) the team of analysts compiles pertinent information on current crop and weather conditions from throughout the country in a standardized, consistent manner. Using the portal traditionally collected data are combined with electronically collected field data and MODIS satellite image time series from GLAM East-Africa (Global Agricultural Monitoring System, customized for stakeholders in East Africa). The main outcome of this work has been the compilation of the National Food Security Bulletin for Tanzania with plans for a public release and the intention for it to become the main avenue to dispense current updates and analysis on agriculture in the country. The same information is also a potential contribution to the international Early Warning Crop Monitor, which currently covers Tanzania

Dark matter statistics for large galaxy catalogs: power spectra and covariance matrices
Klypin, Anatoly; Prada, Francisco
2018-06-01
Large-scale surveys of galaxies require accurate theoretical predictions of the dark matter clustering for thousands of mock galaxy catalogs. We demonstrate that this goal can be achieve with the new Parallel Particle-Mesh (PM) N-body code GLAM at a very low computational cost. We run ˜22, 000 simulations with ˜2 billion particles that provide ˜1% accuracy of the dark matter power spectra P(k) for wave-numbers up to k ˜ 1hMpc-1. Using this large data-set we study the power spectrum covariance matrix. In contrast to many previous analytical and numerical results, we find that the covariance matrix normalised to the power spectrum C(k, k΄)/P(k)P(k΄) has a complex structure of non-diagonal components: an upturn at small k, followed by a minimum at k ≈ 0.1 - 0.2 hMpc-1, and a maximum at k ≈ 0.5 - 0.6 hMpc-1. The normalised covariance matrix strongly evolves with redshift: C(k, k΄)∝δα(t)P(k)P(k΄), where δ is the linear growth factor and α ≈ 1 - 1.25, which indicates that the covariance matrix depends on cosmological parameters. We also show that waves longer than 1h-1Gpc have very little impact on the power spectrum and covariance matrix. This significantly reduces the computational costs and complexity of theoretical predictions: relatively small volume ˜(1h-1Gpc)3 simulations capture the necessary properties of dark matter clustering statistics. As our results also indicate, achieving ˜1% errors in the covariance matrix for k < 0.50 hMpc-1 requires a resolution better than ɛ ˜ 0.5h-1Mpc.

Capacity Building on the Use of Earth Observation for Bridging the Gaps between Science and Policy
Thapa, R. B.; Bajracharya, B.

Although the geospatial technologies and Earth observation (EO) data are getting more accessible, lack of skilled human resources and institutional capacities are the major hurdles in the effective applications in Hindu Kush Himalayan (HKH) region. Designing efficient and cost effective capacity building (CB) programs fitting needs by different users on the use of EO information for decision making will provide options in bridging the gaps in the region. This paper presents the strategies adopted by SERVIR-HKH as an attempt to strengthen the capacity of governments and development stakeholders in the region. SERVIR-HKH hub plays vital role in CB on EO applications by bringing together the leading scientists from the Globe and the key national institutions and stakeholders in the region. We conducted country consultation workshops in Afghanistan, Bangladesh, Pakistan, and Nepal to identify national priorities, requirements and the capacity of the institutions to utilize EO information in decision making. The need assessments were focused on four thematic areas of SERVIR where capacity gaps in utilization of EO data in policy decisions were identified in thirteen key service areas. Geospatial capacities in GIT infrastructure, data, and human resources were varied. Linking EO information to policy decision is mostly lacking. Geospatial data sharing provision among the institutions in the region is poor. We developed a capacity building strategy for HKH region which bridges the gaps in a coordinated manner through customized training programs, institutional strengthening, coordination and regional cooperation. Using the strategy, we conducted training on FEWS NET remote sensing products for agro-climatological analysis, which focused on technical interpretation and analysis of the remote sensing and modeled products, eg, CHIRPS, RFE2, CHIRTS, GFS, NDVI, GeoCLIM and GeoGLAM. Scientists from USGS FEWS NET program delivered the training to mid-level managers and decision

parameters in our model, we were able to reproduce the intervals of the observed frequency peaks of zircon age determinations without essentially changing any of the other results. The results yield a calculated integrated continental growth curve that resembles the curves of GLAM, Begg et al. (2009), Belousova et al. (2010), and Dhuime et al. (2012), although our curve is less smooth and contains distinct variations that are not evident in these other curves.
