description: Relations between photon scattering, entanglement and multi-mode detection are investigated. We first establish a general framework in which one- and two-photon elastic scattering processes can be discussed, then we focus on the study of the intrinsic entanglement degradation caused by a multi-mode detection. We show that any multi-mode scattered state cannot maximally violate the Bell-CHSH inequality because of the momentum spread. The results presented here have general validity and can be applied to both deterministic and random scattering processes.

description: he author gives a brief history of research in nematology of insects. He presents and discusses the principal finding in this discipline, regarding parasitism observed in insects in the neotropical region. Only the parasitic nematodes on the general cavity are dealt with, while nematodes of the medical and veterinarian types are excluded. A briel· account is given of parasitism caused by the following types of nematodes: Allantonematidae, Aphelenchoididae, Merm thidae, Oxyridae, Rhabditidae and Thelastomatidae. The cases of parasitism mentioned in the literature are reportd, but there are few. With the exception of Brazil, in the case of OXYUROIDEA, no country has had a continuing program of studies in this area. The influence of these nematodes on the host insects is discussed: reduction of fertility rate, sterility or mortality. The nematodes, being one of the factors limiting the growth of insect populations, can be used in certain cases in an integrated control program. Many cases of parasitism observed on Chrysomelidae and Nitidulidae (Coieopetera) in French Guyana are presented. The author concludes that our knowledge on the subject is very limited in the neotropical region, and thus a large field of studies remains open.

description: The water column of the Landsort Deep, central Baltic Sea, is stratified into an oxic, suboxic, and anoxic zone. This stratification controls the distributions of individual microbial communities and biogeochemical processes. In summer 2011, particulate organic matter was filtered from these zones using an in situ pump. Lipid biomarkers were extracted from the filters to establish water-column profiles of individual hydrocarbons, alcohols, phospholipid fatty acids, and bacteriohopanepolyols (BHPs). As a reference, a cyanobacterial bloom sampled in summer 2012 in the central Baltic Sea Gotland Deep was analyzed for BHPs. The biomarker data from the surface layer of the oxic zone showed major inputs from cyanobacteria, dinoflagellates, and ciliates, while the underlying cold winter water layer was characterized by a low diversity and abundance of organisms, with copepods as a major group. The suboxic zone supported bacterivorous ciliates, type I aerobic methanotrophic bacteria, sulfate-reducing bacteria, and, most likely, methanogenic archaea. In the anoxic zone, sulfate reducers and archaea were the dominating microorganisms as indicated by the presence of distinctive branched fatty acids: archaeol and pentamethylicosane (PMI) derivatives, respectively. Our study of in situ biomarkers in the Landsort Deep thus provided an integrated insight into the distribution of relevant compounds and describes useful tracers to reconstruct stratified water columns in the geological record.

description: We study the associated production of bottomonia and Higgs bosons at hadron colliders within the factorization formalism of nonrelativistic quantum chromodynamics providing all contributing partonic cross sections in analytic form. While such processes tend to be suppressed in the standard model, they may have interesting cross sections in its minimal supersymmetric extension, especially at large values of tan(beta), where the bottom Yukawa couplings are enhanced. We present numerical results for the processes involving the lighter CP-even h^0 boson and the CP-odd A^0 boson appropriate for the Fermilab Tevatron and the CERN LHC.

description: We prove three exact sum rules that relate the polarization of active Brownian particles to their one-body current: (i) The total polarization vanishes, provided that there is no net flux through the boundaries, (ii) at any planar wall the polarization is determined by the magnitude of the bulk current, and (iii) the total interface polarization between phase-separated fluid states is rigorously determined by the gas-liquid current difference. This result precludes the influence of the total interface polarization on active bulk coexistence and questions the proposed coupling of interface to bulk.

description: Research was conducted in Isabela, Puerto Rico, to determine the tuber productivity of the weed purple nutsedge (PN) and the yield of 'Crimson Sweet' watermelon when grown with or without organic soil bed mulches [hays of millet (Pennisetum glaucum), nutsedge (Cyperus rotundus), sunn hemp (Crotalaria juncea), sorghum (Sorghum bicolor), cowpea ( Vigna unguiculata), cogongrass (Imperata cylindrica), Bahiagrass (Paspalum notatum), and rye (Secale cereale)]. The mulches covered the top of the soil beds, and were set the same day the watermelon was established. Natural populations of PN on the site were approximately 100 viable tubers/m2. PN shoots able to grow through the mulches were left unchecked until the final harvest of the crop. For non-mulched checks, we had a bare soil weed-free treatment and a bare soil season-long-PN-infested treatment. There were significant effects on watermelon yield and PN tuber productivity by mulch material. The tuber productivity of PN production was significantly reduced when watermelon was mulched with Bahiagrass (68% lower), nutsedge (45% lower), cogongrass (36% lower), millet (36% lower), and sorghum (34% lower), as compared to PN-infested checks. When mulching with cogongrass and nutsedge, watermelon yield was significantly higher than with other mulches.

description: The proof by Ullmo and Zhang of Bogomolov's conjecture about points of small height in abelian varieties made a crucial use of an equidistribution property for ``small points'' in the associated complex abelian variety. We study the analogous equidistribution property at $p$-adic places. Our results can be conveniently stated within the framework of the analytic spaces defined by Berkovich. The first one is valid in any dimension but is restricted to ``algebraic metrics'', the second one is valid for curves, but allows for more general metrics, in particular to the normalized heights with respect to dynamical systems.

Deciphering fluid inclusions in high-grade rocks
Creators: name: Van Den Kerkhof, Alfons
name: Kronz, Andreas
name: Simon, Klaus
Publisher: name: FID GEO
Year: 2014

description: The study of fluid inclusions in high-grade rocks is especially challenging as the host minerals have been normally subjected to deformation, recrystallization and fluid-rock interaction so that primary inclusions, formed at the peak of metamorphism are rare. The larger part of the fluid inclusions found in metamorphic minerals is typically modified during uplift. These late processes may strongly disguise the characteristics of the “original” peak metamorphic fluid. A detailed microstructural analysis of the host minerals, notably quartz, is therefore indispensable for a proper interpretation of fluid inclusions. Cathodoluminescence (CL) techniques combined with trace element analysis of quartz (EPMA, LA-ICPMS) have shown to be very helpful in deciphering the rock-fluid evolution. Whereas high-grade metamorphic quartz may have relatively high contents of trace elements like Ti and Al, low-temperature re-equilibrated quartz typically shows reduced trace element concentrations. The resulting microstructures in CL can be basically distinguished in diffusion patterns (along microfractures and grain boundaries), and secondary quartz formed by dissolution-reprecipitation. Most of these textures are formed during retrograde fluid-controlled processes between ca. 220 and 500 °C, i.e. the range of semi-brittle deformation (greenschist-facies) and can be correlated with the fluid inclusions. In this way modified and re-trapped fluids can be identified, even when there are no optical features observed under the microscope.

Quantum wave packet revivals

Year: 2004
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The numerical prediction, theoretical analysis, and experimental verification of the phenomenon of wave packet revivals in quantum systems has flourished over the last decade and a half. Quantum revivals are characterized by initially localized quantum states which have a short-term, quasi-classical time evolution, which then can spread significantly over several orbits, only to reform later in the form of a quantum revival in which the spreading reverses itself, the wave packet relocalizes, and the semi-classical periodicity is once again evident. Relocalization of the initial wave packet into a number of smaller copies of the initial packet (`minipackets' or `clones') is also possible, giving rise to fractional revivals. Systems exhibiting such behavior are a fundamental realization of time-dependent interference phenomena for bound states with quantized energies in quantum mechanics and are therefore of wide interest in the physics and chemistry communities. We review the theoretical machinery of quantum wave packet construction leading to the existence of revivals and fractional revivals, in systems with one (or more) quantum number(s), as well as discussing how information on the classical period and revival time is encoded in the energy eigenvalue spectrum. We discuss a number of one-dimensional model systems which exhibit revival behavior, including the infinite well, the quantum bouncer, and others, as well as several two-dimensional integrable quantum billiard systems. Finally, we briefly review the experimental evidence for wave packet revivals in atomic, molecular, and other systems, and related revival phenomena in condensed matter and optical systems.

title: The hydrogeology of the Oman Mountains
Creators: name: Stanger, Gordon
Publisher: name: The Open University
Year: 1986

description: Northern Oman is an arid area almost entirely dependent upon groundwater recharged by highly sporadic rainfall. Precipitation estimates are hampered by a lack of any reliable altitude-rainfall relationship. Below 700 m there is no statistically significant relationship. The isotopic composition of groundwater is strongly influenced by the rainfall amount (related to storm frequency), and not just by altitude/temperature. Storm events with long return periods are of disproportionate importance to recharge. Despite the huge volume of carbonate formations, holokarstic development is generally immature, and groundwater storage is greatest in alluvial piedmont surrounding main limestone massifs. Isotopes, chemistry and hydrologic measurements show that post-storm evaporative losses are very large. The origin of limestone springs and their chemical and physical anomalies are described. Structure rather than petrology controls groundwater flow in the limestones, hence regional differences in structural style produce contrasting hydrologic regimes between the various massifs. The Semail nappe mantle sequence is the only other hard-rock formation of groundwater significance. Though much less productive than the carbonates, these ultramafics display extraordinary chemical activity, yielding bicarbonate waters from the weathered zone, whilst more deeply circulating groundwaters produce hyperalkaline springs by low-temperature serpentinisation. Associated processes include solute reduction, hydrogen evolution, hydroxide and carbonate precipitation, hydroxide-basic rock reaction, salt enrichment and water-rock isotopic exchange. Throughout the interior catchments, groundwater mostly flows into narrow buried alluvial channels which are often constricted at hard-rock nodal points, thus facilitating very efficient interception and recovery by the "falaj" system. Traditional agriculture has evolved to cope with fluctuating groundwater supply but is sensitive to increased abstraction. On the Batinah plain, greatly increased coastal abstraction has locally induced moderate to severe salinisation. Existing process studies are insufficiently quantified to provide the resolution necessary to manage groundwater resources, especially in high-risk coastal areas.

description: Consider a distributed task where the communication network is fixed but the local inputs given to the nodes of the distributed system may change over time. In this work, we explore the following question: if some of the local inputs change, can an existing solution be updated efficiently, in a dynamic and distributed manner? To address this question, we define the batch dynamic CONGEST model in which we are given a bandwidth-limited communication network and a dynamic edge labelling defines the problem input. The task is to maintain a solution to a graph problem on the labeled graph under batch changes. We investigate, when a batch of $α$ edge label changes arrive, -- how much time as a function of $α$ we need to update an existing solution, and -- how much information the nodes have to keep in local memory between batches in order to update the solution quickly. Our work lays the foundations for the theory of input-dynamic distributed network algorithms. We give a general picture of the complexity landscape in this model, design both universal algorithms and algorithms for concrete problems, and present a general framework for lower bounds. In particular, we derive non-trivial upper bounds for two selected, contrasting problems: maintaining a minimum spanning tree and detecting cliques.
On the Validity of Specific Rate Constants (kSA) in Fe0/H2O Systems

Publisher: name: FID GEO
Year: 2008

description: The validity of the specific reaction rate constants (k(SA)) in modelling contaminant removal in Fe-0/H2O systems is questioned. It is shown that the current k(SA)-model does not consider the large reactive surface area provided by the in-situ formed oxide film, and thus the adsorptive interactions between contaminants and film materials. Furthermore, neither the dynamic nature of film formation nor the fact that the Fe-0 surface is shielded by the film is considered. Suggestions are made how the k(SA)-model could be further developed to meet its original goal.

description: Food safety starts at the farm gate. Proper management and feeding are important to the productivity and survivability of the farm as well as to the health and safety of the food supply. Nutrition and internal parasites are two factors that affect the growth of the meat goat industry in Florida. The project evaluated three common feeding strategies [(i) a cracked corn feed, (ii) a 12% crude protein commercial feed, and (iii) a 16% crude protein commercial feed)] and three anthelmintics for their effects on weight gain and economic efficiency, and any resistance among the herd, respectively. The results indicated that the 12% crude protein commercial feed-feeding regimen was the most economical / sustainable, and had the lowest weight gain. In addition, the results indicated that Florida A&M University, Research Extension Center herd might be resistant to the Levamisole type anthelmintic. One of the objectives, also, was to apply the most efficient resources to maintain food safety. The aim is to attain healthier animals through proper nutrition, weight gain and carcass quality, thereby maximizing safe food supply.

De igual manera es relevante la forma como los colaboradores gestionan sus emociones en los momentos de tensión y estrés para lograr responder en forma asertiva a sus requerimientos en el puesto, con compañeros y clientes. Otro factor que incide es la valoración y reconocimiento de los aportes personales, en los equipos, sus líderes y la organización.Por otra parte, es necesario reconocer que en las organizaciones se pueden dar conflictos, los cuales deben ser afrontados positivamente, y reconocer que un conflicto bien manejado puede apoyar a la creatividad e innovación organizacional y de los grupos. Para esto es adecuado utilizar técnicas y estrategias que permitan a los colaboradores analizar las situaciones desde una perspectiva más amplia.

description: Black Sigatoka (aka black leaf streak), caused by the fungus Mycosphaerella fijiensis, and Moko disease, caused by the bacterium Ralstonia solancearum phylotype II, are among the most destructive diseases of banana. Black Sigatoka first appeared in the Western Hemisphere in Honduras in 1972, and then spread rapidly to other producing areas on the mainland. However, its movement in the Caribbean Islands has been slower and less extensive. The history of Moko disease is similar, in that it is widely spread in mainland tropical America but is still absent on most of the Caribbean Islands. Inter-island dispersal of M. fijiensis and R. solancearum is constrained by several factors. The pathogens are disseminated most effectively by man, but are thought to spread naturally up to, respectively, 200 and 90 km. Given the later possibilities and the distances that are involved, natural spread in most outbreaks of these diseases in the Caribbean cannot be ruled out. Only the arrival of black Sigatoka in Cuba, Florida and Jamaica, and that of Moko disease in Grenada and Jamaica are clearly the result of anthropogenic dissemination. The future spread and impact of these diseases in the region is discussed.

description: Information security management aims at ensuring proper protection of information values and information processing systems (i.e. assets). Information security risk management techniques are incorporated to deal with threats and vulnerabilities that impose risks to information security properties of these assets. This paper investigates the current state of risk management practices being used in information security management in the DACH region (Germany, Austria, Switzerland). We used an anonymous online survey targeting strategic and operative information security and risk managers and collected data from 26 organizations. We analyzed general practices, documentation artifacts, patterns of stakeholder collaboration as well as tool types and data sources used by enterprises to conduct information security management activities. Our findings show that the state of practice of information security risk management is in need of improvement. Current industrial practice heavily relies on manual data collection and complex potentially subjective decision processes with multiple stakeholders involved. Dedicated risk management tools and methods are used selectively and neglected in favor of general-purpose documentation tools and direct communication between stakeholders. In light of our results we propose guidelines for the development of risk management practices that are better aligned with the current operational situation in information security management.

description: St. Thomas, the busiest island of the US Virgin Islands, is small (81km2) but has a population of 53,000 people (population density: 654.3 people/km2) that does not include the 1.5 million annual tourists. While steep slopes make for attractive seascape views, it means that there is little suitable land for agriculture. Land zoned for agriculture is under constant threat of re-classification to make room for more lucrative residential/tourist/commercial developments. Agricultural inputs are scarce and costly. Water resources are limited and unreliable. Agricultural productivity is low and even though markets are strong and prices high, very few people can commit to full-time farming. Establishing a productive agricultural base that can economically support producers and justify continued government support may require the institutional support of non-traditional producers. These producers include small-scale, home gardeners. The fact that they outnumber full-time farmers reflects the urban characteristics of the island and helps understand the particular farming system found on St Thomas. Extension efforts that rely on full-time farmers as vehicles of change do not acknowledge the limitations of the St. Thomas farming system. Adapting to a different client type may be the best way of spending extension dollars. Broad, educational initiatives, community programs and an appropriate scaling of technological packages will feed into the general interest on the island for food security, lowered grocery bills and better food quality. Fundamental to these extension efforts is to make non-traditional producers believe that they can be active participants in the island's food economy.
Arsenic Release from a Natural Rock under Near-natural Oxidizing Conditions

description: The effects of carbonate concentration and the presence of iron hydroxide phases on the process of arsenic release from an ore material were investigated under experimental oxic conditions and in the pH range from 6.0 to 9.0. These experimental conditions are pertinent to arsenic leaching from tailings and mining wastes. The leaching tests lasted for <= 99 days and were performed with materials of five different particle sizes (<= 2 mm). Carbonate ions were produced in-situ by dolomite dissolution or were contained in used waters (0 to 30 mM as HCO(3)(-)) Iron hydroxide phases were formed in situ by oxidative dissolution of metallic iron (Fe(0)) or pyrite (FeS(2)). Non-disturbed batch experiments and air-homogenized experiments were conducted with a constant amount (10 g/L) of an arsenic-bearing rock (ore material) of a given particle size and different types of water (deionized, tap and mineral water). For comparison, experiments were conducted with 0.1 M EDTA, 0.1 M Na(2)CO(3), and 0.1 M H(2)SO(4). Neither the use of dolomite nor the use of water containing various carbonate (HCO(3)(-)) concentrations could confirm the recent results on the favorable role of As(III)-carbonate complexes on the arsenic transport in the environment. On the other hand, iron hydroxide phases (from Fe(0) and FeS(2)) univocally delayed the As release in both experimental procedures. Furthermore, the theoretically expected effects of the particle size of the ore material was observed. If one takes into consideration that the used HCO(3)(-) concentrations were up to six times larger then those of natural surface waters (<= 5.5 mM) but up to five times lower than those currently used in the literature (>= 100 mM), it is concluded that the reported conflicting results for As leaching from sediments may be a misinterpretation of processes occurring in the sediment and yielding increased As release with increasing HCO(3)(-)/CO(3)(2-) concentration.

description: The giant African snail (GAS), Achatina fulica, is native to East Africa, and is now very widely distributed and established across the Indo-Pacific region. In 1984, this pest was first reported in the Caribbean sub-region in Guadeloupe and has spread since to several other countries. The only other report for the wider Caribbean Basin is for Florida, United States of America, where the pest was introduced in the late-1960s. GAS has been described as the most damaging land snail world-wide, reportedly attacking over 500 plant species inclusive of tree crops, ornamentals, vegetables and root crops; it has also been reported to vector several plant pathogens. Achatina fulica is therefore considered a major agricultural and horticultural pest species. Additionally, GAS is of public health concern being an intermediate host and vector of the parasitic rat lungworm, Angiostrongylus cantonensis, the agent of the human disease, eosinophilic meningitis (or cerebral angiostrongyliasis). However, in most of the affected countries in the Caribbean, the snail has not proved to be a major pest, mainly affecting household gardens and uncultivated or semi-wild areas; the few reports of agricultural losses involve mainly vegetables. Management of this pest in several of the affected countries consists mainly of the use of chemical baits and physical collection of snails combined with limited public awareness programmes. While its spread to date has been slow, the establishment of the giant African snail in the Caribbean is a cause for concern for the agricultural sector and, lesser so, as a potential public health problem. However, it should be noted that the spread of GAS has not been anywhere near the rapid spread of other recently introduced invasive alien species in the Caribbean sub-region, e.g. hibiscus mealybug or red palm mite and neither has the impact been as devastating.

description: Recently the BES collaboration has announced observation of a resonant state in the $π^+π^- η'$ spectrum in $J/ψ\to γπ^+π^-η'$ decay. Fitting the data with a $0^{-+}$ state, the mass is determined to be 1833.7 MeV with $7.7σ$ statistic significance. This state is consistent with the one extracted from previously reported $p \bar p$ threshold enhancement data in $J/ψ\to γp \bar p$. We study the properties of this state using QCD anomaly and QCD sum rules assuming X(1835) to be a pseudoscalar and show that it is consistent with data. We find that this state has a sizeable matrix element $<0|G\tilde G|G_p>$ leading to branching ratios of $(2.61\sim 7.37)\times 10^{-3}$ and $(2.21\sim 10.61)\times 10^{-2}$ for $J/ψ\to γG_p$ and for $G_p \to π^+π^- η'$, respectively. Combining the calculated branching ratio of $J/ψ\to γG_p$ and data on threshold enhancement in $J/ψ\to γp \bar p$, we determine the coupling for $G_p- p-\bar p$ interaction. We finally study branching ratios of other $J/ψ\to γ+ {three mesons}$ decay modes. We find that $J/ψ\to γG_p \to γ(π^+π^- η, K K π^0)$ can provide useful tests for the mechanism proposed.

description: MicroRNAs (miRNAs) are emerging as important, albeit poorly characterized, regulators of gene expression. Here, I review the current knowledge of miRNAs in humans, including their biogenesis, modes of action and various methods for studying them. To fully elucidate the various functions of miRNAs in humans, we require a more complete understanding of their numbers and expression changes amongst different cell types. This document includes a description of a new method for surveying the expression of miRNAs that employs the new Illumina sequencing technology. A set of methods is presented that enables identification of sequences belonging to known miRNAs as well as variability in their mature sequences. As well, a novel system for miRNA gene discovery using these data is described. Application of this approach to RNA from human embryonic stem cells (hESCs) obtained before and after differentiation into embryoid bodies (EBs) revealed the sequences and expression levels of 362 known plus 170 novel miRNA genes. Of these, 190 known and 31 novel microRNA sequences exhibited significant expression differences between these two developmental states. Owing to the increased number of sequence reads, these libraries currently represent the deepest miRNA sampling in any human cell type spanning nearly six orders of magnitude of expression. Predicted targets of the differentially expressed miRNAs were ranked to identify those that are likely under cooperative miRNA regulation in either hESCs or EBs. The predicted targets of those miRNAs enriched in either sample shared common features. Included amongst the high-ranked predicted gene targets are those implicated in differentiation, cell cycle control, programmed cell death and transcriptional regulation. Direct validation of these predicted targets or global discovery of miRNA targets should reveal the functions of these sequences in the differentiation of hESCs.

description: MORMOOPIDAE   Although we collected only one mormoopid species at Paracou, another two could plausibly be expected to occur in the area (appendix 1). Smith’s (1972) revision of the family is still the standard reference for identifying species of Pteronotus, the only mormoopid genus widespread in South American rainforests.

description: Coffee production in the Caribbean and Latin America is an important commodity in terms of economic, ecological and social value. Coffee production in Puerto Rico was intensified in the 1960s, with a shift to higher-yield varieties, increased use of pesticides and fertilizers, increased mechanization, higher-density planting patterns, with production under full sunlight. There is concern that long-term, intensive coffee production under full sunlight may have a negative impact on agroecosystem sustainability. Soil physical, chemical and biological attributes from representative major coffee production regions in Puerto Rico under partial shade and full sunlight were quantified. Soils from secondary forests at least 25 years old were included for comparison. Soil fertility differed between forest and coffee agroecosystems with favorable soil reaction, improved nutrient reserves and availability in forested systems; coffee under shade had a tendency towards improved soil fertility. The soil physical structure was significantly affected by coffee production, with a greater proportion of large macroaggregates in forested sites than in coffee agroecosystems. Coffee under both partial shade and full sunlight had a lower proportion of macroaggregates and a higher proportion of microaggregates which may have important implications for the capacity of soils under coffee production to store C and release Ν for crops. Soil organic carbon and nitrogen, microbial biomass and fungal groups were negatively affected by coffee production, with few observed differences between coffee under shade and full sunlight. The soil biological community structure was negatively influenced by coffee production relative to secondary forested sites, with coffee under shade having slight improvement relative to coffee under sun.

description: PHYLLOSTOMIDAE   The generic and higher level classification of phyllostomids used herein follows Peffley et al. (MS). Notable changes from current usage (Koopman, 1993) include our use of Glossophaginae to include lonchophyllines, our recognition of Glyphonycteris and Trinycteris (formerly included in Micronycteris) as full genera, and our use of Ectophylla to include Mesophylla. Emended diagnoses of Glyphonycteris, Micronycteris, Trinycteris, and Ectophylla are provided to justify these new usages.
In the course of our fieldwork at Paracou we captured 49 phyllostomid species belonging to the subfamilies Desmodontinae (2 species), Glossophaginae (5 species), Phyllostominae (25 species), Carolliinae (2 species), and Stenodermatinae (15 species). An additional 15 species (3 glossophagines, 4 phyllostomines, 1 carolliine, and 7 stenodermatines) are known from other collecting localities in French Guiana and Surinam (appendix 1), and some of these could also be expected to occur in our study area. One of the phyllostomid species reported below is described as a new species, and two others were previously unknown from French Guiana.

description: Most recommendation engines today are based on predicting user engagement, e.g. predicting whether a user will click on an item or not. However, there is potentially a large gap between engagement signals and a desired notion of "value" that is worth optimizing for. We use the framework of measurement theory to (a) confront the designer with a normative question about what the designer values, (b) provide a general latent variable model approach that can be used to operationalize the target construct and directly optimize for it, and (c) guide the designer in evaluating and revising their operationalization. We implement our approach on the Twitter platform on millions of users. In line with established approaches to assessing the validity of measurements, we perform a qualitative evaluation of how well our model captures a desired notion of "value".

description: Dairy manure sludge (DMS) application to grazed forage pastures is a widespread agronomic practice. Unfortunately, the quantitative benefits of DMS application to improved pastures still has not been shown in the Caribbean. On-going application of DMS based on estimated nitrogen (N) content is unsustainable, and in many areas presents a threat to water quality, because the excess phosphorus (P) in dairy sludge is usually not extracted by plants and remains in soil until removed in runoff. Application of DMS based on Ρ content of the material may be a better alternative, but pastures may need to be supplemented with N. The nutrient concentration of DMS sludge in various farms of Puerto Rico was assessed. The mean (standard deviation in parenthesis) nutrient concentration of DMS (n=17) was 233 (120), 122 (77), 232 (123) mg/L for total N, total P, and total K, respectively. The economic benefit of DMS application, in terms of substitution for the price of nutrients in mineral fertilizer, could be from $79 to $158 per ha-cm (acre-in) of application, but the excess volume of DMS application from the improper application could offset potential agronomic and economic gains. Farmers applying DMS to fields should take every precaution to ensure that the infiltration rate of the soil is not exceeded and that during the application the volumes are kept to levels in which the nutrients applied do not exceed crop nutrient requirements. Further precautions include reducing the number of applications during the year and spreading the material to other areas of the farms. A case study demonstrated that there is an excess of nutrients generated on-farm which originate primarily from grazing animals, and is exacerbated by high animal densities, improper distribution of Ν and Ρ from DMS and fertilizer. Excess nutrients generated result in unsustainable nutrient rates to fields which could result in a waste of resources and environmental degradation.
