description: The following section is a discussion of the importance of the problem of agricultural nonpoint source pollution, the conceptual framework and methods, and the research objectives of this study. Agricultural nonpoint source pollution is an important environmental concern. Agricultural nonpoint sources have been identified as the major contributors to sediments, nutrients, pathogenic bacteria, and pesticides affecting surface water quality (NRC, 1993). Severe soil degradation from erosion, compaction, or salinization, can damage the productive capacity of the soil and exacerbate water pollution. Sediments from eroded croplands interfere with the use of bodies of water for transportation; reduce the life of dams, locks, reservoirs, and other water developments; and degrade aquatic ecosystems. Nutrients accelerate the rate of eutrophication of lakes, streams, and estuaries; and nitrogen may cause health problems if ingested by humans in drinking water. Pesticides in drinking water, may become a human health concern and have been accused of disrupting reproduction of life in aquatic ecosystems (Overcash and Davidson, 1980). Statistics suggest that agriculture is the primary source of nonpoint pollution, affecting 64 percent of polluted U.S. rivers and 57 percent of impaired U.S. lakes (Figures 1-2). Nutrients (nitrogen and phosphorous) and sediments, the major types of pollutants closely associated with agricultural production, severely affect surface water quality in the United States (Figures 3-4) and loadings of these pollutants have increased in agricultural watersheds. These nutrients account for 13 percent of the destruction in U.S. rivers and 59 percent in U.S. lakes, making it the leading source of impairment in U.S. lakes (Smith et al., 1987).

description: The information entropies in coordinate and momentum spaces and their sum ($S_r$, $S_k$, $S$) are evaluated for many nuclei using "experimental" densities or/and momentum distributions. The results are compared with the harmonic oscillator model and with the short-range correlated distributions. It is found that $S_r$ depends strongly on $\ln A$ and does not depend very much on the model. The behaviour of $S_k$ is opposite. The various cases we consider can be classified according to either the quantity of the experimental data we use or by the values of $S$, i.e., the increase of the quality of the density and of the momentum distributions leads to an increase of the values of $S$. In all cases, apart from the linear relation $S=a+b\ln A$, the linear relation $S=a_V+b_V \ln V$ also holds. V is the mean volume of the nucleus. If $S$ is considered as an ensemble entropy, a relation between $A$ or $V$ and the ensemble volume can be found. Finally, comparing different electron scattering experiments for the same nucleus, it is found that the larger the momentum transfer ranges, the larger the information entropy is. It is concluded that $S$ could be used to compare different experiments for the same nucleus and to choose the most reliable one.

description: Farm resource allocation decision, particularly in developing countries, is generally a risky process. The uncertainty related to yields and farm product prices suggests that farmers behave in risk-averse ways. This research uses linear programming models under a risk framework to investigate about cropping patterns and technologies most profitable to farmers in two Senegalese zones: The Center of the Peanut Basin and the Upper Casamance. Normative supply responses are derived for the two agricultural zones investigated under a food security perspective by making assumptions about farm price levels. In the Central Peanut Basin, acreage under cultivation does not respond to price increases; supply responses have constant slopes. In the Upper Casamance zone, interesting aspects of land competition between crops is found. Among all crops, maize showed higher acreage responses to price increases.

Operational Characteristics of Lane Drops

Subjects: subject: Transportation Engineering

description: A lane drop is defined as a location on a highway where the number of lanes provided for through traffic decreases. For purposes of this study, the broad category of lane drops has been further subdivided into three specific classes: lane exits, lane splits, and lane terminations. These subdivisions are illustrated schematically in Figure 1. A lane exit refers to a location where the number of through lanes decreases at an interchange on a multilane roadway. A designation of lane split denotes a major fork of a multilane highway where the level of traffic service provided at the terminus of either prong is approximately equal. Thus, the lane split does not have the same exit connotation which is associated with a lane exit. The third category is the lane termination which occurs when a lane is simply terminated. A lane termination leaves a driver with no choice, he must merge into the other available lane(s). A lane termination also has no connection with an exiting situation.  Associated with the first two categories, lane exits and lane splits, is the concept of driver decision. The driver who is confident of his destination and the proper path thereto generally presents no conflict with the flow of traffic. The problem arises largely from those drivers who are inattentive, intoxicated, uncertain of how to reach their destination, and(or) have improper driving habits. It is these individuals, as shown in Figure 2, who conflict with the traffic stream. Therefore, it is imperative that the driver be made aware of the necessity for an early decision regarding his course of travel. The driver who makes an errant decision and abides by it is not as dangerous as the one who makes a delayed decision and attempts, often too late, to correct it. Thus, the driver who perchance takes the wrong branch is likely to resort to desperation tactics and back up or undertake some other maneuver that is illegal or contrary to safety.  The purpose of the study reported herein was to evaluate the operational characteristics of lane-drop situations as they are influenced by various fore-warning, decision-demanding messages. More specifically, the immediate purpose was to discover types of signs, pavement markings, and lane delineations which minimize or reduce erratic movements at existing lane drops. It was also hoped that an optimum design criteria for lane-drop situations might be determined.  Several standard and untried traffic control devices were selected for experimentation. A pilot study at a geographically advantageous location containing three lane splits was conducted. The results of this pilot study are the subject of this report.

description: The Argentine Institute of Radio astronomy (IAR) is equipped with two single-dish 30-m radio antennas capable of performing daily observations of pulsars and radio transients in the southern hemisphere at 1.4 GHz. We aim to contribute to pulsar timing studies related to short time-scale interstellar scintillation and searches for sources of continuous gravitational waves. We performed high-cadence (almost daily) and long-duration observations of the bright millisecond pulsar J0437$-$4715 for over a year, gathering more than 700 hours of good-quality data with timing precision better than 1~$μ$s. We characterize the white and red timing noise in IAR's observations of J0437$-$4715. We quantify the effects of scintillation in this data set and perform single pulsar searches of continuous gravitational waves, setting constraints in the nHz--$μ$Hz frequency range. We demonstrate IAR's potential for performing pulsar monitoring in the 1.4 GHz radio band for long periods of time with a daily cadence. In particular, we conclude that the ongoing observational campaign of the millisecond pulsar J0437$-$4715 can contribute to increase the sensitivity of the existing pulsar timing arrays.

description: This paper explores the link between cost and price in two irrigation schemes in Mali - the Office du Niger (ON), a large-scale gravity irrigation authority, and a number of small pump-irrigated fields at village perimeters along the Niger River (Petits Perimetres d'Irrigation Villagois). I argue that the effectiveness of cost-recovery pricing strategies for improving the long-run financial sustainability of irrigation systems and advancing national development objectives is a function of decision-making processes, which influence the distribution and absolute levels of cost and benefit flows. Participants' willingness and capacity to invest in problem solving play an important part in irrigation system viability by increasing the rate of technological and institutional change, which can increase benefits and decrease costs of production. Understanding formal and informal relationships between service users and service providers can help reveal institution-based sources of incentives and disincentives for parties to invest in producing effort and solving problems. The paper examines the price strategies in two case studies and the relationships among stakeholders in the design and implementation of each system's price strategies. Institutional theory suggests ways to align individual incentives with the objectives of the pricing strategy; targeted investments may be needed to provide participants with the means to act on institutionally designed incentives.

description: Lifting of water for irrigation in the Northern and Khartoum provinces of Sudan depends mainly on fuel and electrical pumps, while in Egypt more than 70% of irrigation is done by an animal drawn implement call the "Sagiya". The shortage of fuel and electricity which started in the early seventies has resulted in a sharp reduction of agricultural output in Sudan both vertically and horizontally. This paper demonstrates the possibility that the transfer of the Egyptian "Sagina" to Sudan may help increase the agricultural output and/or decrease the cost of production per unit of output.

description: We present contactless atomic-force microscopy measurements of the hydrodynamic interactions between a rigid sphere and an air bubble in water at the micro-scale. The size of the bubble is found to have a significant effect on the response due to the long-range capillary deformation of the air-water interface. To rationalize the experimental data, we develop a viscocapillary lubrication model accounting for the finite-size effect. The comparison between experiments and theory allows us to measure the air-water surface tension, without contact, paving the way towards robust contactless tensiometry of polluted air-water interfaces.

description: The problem of unemployment in Colombia is very important for a variety of reasons. A large portion of it can be identified as technological unemployment. This kind of unemployment is related to the technological dualism, which exists in the economy. Technological unemployment arises from technological and resource restraints in both sectors, and due to the current composition of effective demand. The traditional sector uses a technology which is relatively labor-intensive, and depends heavily on simple tools produced domestically. In contrast, the modern sector uses imported production processes which are relatively capital-intensive and with a limited degree of flexibility in the substitution of labor for capital. But, labor is abundant, and capital is scarce, in Colombia. Yet, Colombia's consumers seem to prefer a product-mix with a high proportion of goods produced by the modern sector and a relatively low proportion of goods produced by the traditional sector. In providing this product-mix the economy cannot reach full employment of labor. The result is technological unemployment.

 Diagnosis and remarks. Heteragrion simulatum shares a high degree of morphological similarity with H. icterops and H. breweri, with most of their characters except for coloration being identical according to De Marmels (1989). In other words, the head color pattern in H. simulatum is quite darker than in H. icterops and H. breweri, the latter having the most yellow areas between the three. Nevertheless, this species can be distinguished from other Group B (except H. icterops and H. breweri) species based on the following combination of characters: ridge above ML long, sinuous consisting of small teeth, and a marked carina (Fig. 61d); in lateral view, ML bent downwards (Fig. 61e); AP the shortest (Fig. 61d); S9–10 paler.

description: There are four major types of wine: table wine, dessert wine, sparkling wines and champagnes, and vermouth. Greatest attention is focused upon table wines because of the prominent role they have come to play in the industry. In 1960, only 30% of all wine consumed in the U.S. was table wine. By 1970, this percentage had grown to 50 and by 1980 it is expected that 80% of U.S. wine consumption will be of this type.

description: The coherent electron spin dynamics of an ensemble of singly charged (In,Ga)As/GaAs quantum dots in a transverse magnetic field is driven by periodic optical excitation at 1 GHz repetition frequency. Despite the strong inhomogeneity of the electron $g$ factor, the spectral spread of optical transitions, and the broad distribution of nuclear spin fluctuations, we are able to push the whole ensemble of excited spins into a single Larmor precession mode that is commensurate with the laser repetition frequency. Furthermore, we demonstrate that an optical detuning of the pump pulses from the probed optical transitions induces a directed dynamic nuclear polarization and leads to a discretization of the total magnetic field acting on the electron ensemble. Finally, we show that the highly periodic optical excitation can be used as universal tool for strongly reducing the nuclear spin fluctuations and preparation of a robust nuclear environment for subsequent manipulation of the electron spins, also at varying operation frequencies.

description: Senegal imports about 200,000 tons of rice annually. These import consume a large share of the national budget and represent a heavy outflow of foreign exchange. Despite the implementation of various agricultural projects aimed at increasing domestic rice production, Senegal still relies on imports to fill its deficit and there is no evidence that the situation will change in the near future. The purpose of this paper is to identify and analyze selected factors which are believed to impede expansion of rice production in the Casamance (southern) region of Senegal. The following factors are studied: 1) climatic uncertainties (effects of the drought); 2) the competition between groundnuts and rice for the allocation of family labor; 3) the institutional constraints upon the marketing system in general and processing in particular; and 4) the effects of migration. The results of this analysis suggest that results from the present rice production-marketing subsystem could be significantly improved if more consistent price and marketing policies were defined and applied, and if production and credit were reorganized.

description: This paper presents an application of matching on propensity score to evaluate the impact of the Chesapeake Bay Program (CBP) on farmers' willingness to participate in the United States Department of Agriculture Environmental Quality Incentive Program (EQIP). One goal of the CBP is to reduce agricultural nutrient loadings to Chesapeake Bay. Achievement of this goal will require increased farm adoption of conservation practices to limit and reduce the levels of residual nutrients the bay. One expectation of this investigation is that the CBP's agricultural related research and educational outreach programs directed to the farm community has a positive effect on farmers' willingness to enroll in conservation programs. Furthermore, the CBP funding to support county watershed technicians who assist farm operators with adoption of conservation practices is expected to also have a positive impact on farmers' willingness to enroll in EQIP. EQIP is the leading federal conservation program for cost-share funding for structural, vegetative, and land management practices to reduce agricultural non-point source pollution. The study is limited in scope. The analysis is conducted over one state, Pennsylvania, and analyzes the impact of the CBP only on one program, EQIP. The study is not presented as a comprehensive evaluation of the CBP's impact on all farm conservation programs administered within the Chesapeake Bay watershed. However, the estimation method used for this study can be extended to other farm conservation programs.

description: Fisheries managers in the United States are required to identify and mitigate the adverse impacts of fishing activity on essential fish habitat (EFH). There are additional concerns that the viability of noncommercial species, animals that are habitat dependent and/or are themselves constituents of fishery habitat may still be threatened. We consider a cap-and-trade system for habitat conservation, individual habitat quotas for fisheries, to achieve habitat conservation and species protection goals cost effectively. Individual quotas of habitat impact units (HIUs) would be distributed to fishers with an aggregate quota set to maintain a target habitat 'stock' of EFH conservation. Using a dynamic, spatially explicit fishery simulation model we explore the efficiency and cost effectiveness of an IHQ policy versus alternative marine protected area (MPA) configurations, at reducing the risk of extinguishing a habitat dependent species of unknown spatial distribution. Our findings indicate that an IHQ policy with a conservatively established habitat target is better suited to the protection of non-target species than a rotating or fixed MPA policy.

description: We present the complete set of thirty four ASCA observations of non-magnetic cataclysmic variables. Timing analysis reveals large X-ray flux variations in dwarf novae in outburst (Z Cam, SS Cyg and SU UMa) and orbital modulation in high inclination systems (including OY Car, HT Cas, U Gem, T Leo). We also found episodes of unusually low accretion rate during quiescence (VW Hyi and SS Cyg). Spectral analysis reveals broad temperature distributions in individual systems, with emission weighted to lower temperatures in dwarf novae in outburst. Absorption in excess of interstellar values is required in dwarf novae in outburst, but not in quiescence. We also find evidence for sub-solar abundances and X-ray reflection in the brightest systems. LS Peg, V426 Oph and EI UMa have X-ray spectra that are distinct from the rest of the sample and all three exhibit candidate X-ray periodicities. We argue that they should be reclassified as intermediate polars. In the case of V345 Pav we found that the X-ray source had been previously misidentified.

Navigating uncharted territory: experiences of families when a child has a neurodegenerative life threatening illness
Creators: name: Steele, Rose Guiller

description: Children with neurodegenerative, life-threatening illnesses account for a significant proportion of children requiring palliative care. Most of their care is provided at home by their families. Yet, there is a paucity of research that examines families' experiences when a child is dying at home. This grounded theory study generated a contextually-grounded description of families' experiences of living with a child who has a neurodegenerative, life-threatening illness, and how those experiences changed over time; the impact on families; and families' perceptions of factors that influenced their ability to care for their children. Data were collected from eight families through observations and audiotaped interviews. Families moved through a process of navigating uncharted territory as they lived with their dying child. This process occurred within the broader context of the acute, curative health care system and the sociocultural environment. The process was initiated by a precipitating event, such as one parent recognizing a deterioration in the child's motor skills. The emotions of fear, uncertainty, and grief gave impetus to the process. These emotions were very strong in the beginning. They gradually declined over time, but increased with subsequent precipitating events. Families lived much of their lives on plateaus of relative stability where they often felt alone and isolated from health care professionals. Inevitably, periods of instability originated in subsequent precipitating events in the process that led to families dropping off the plateau. Living with a dying child had a profound physical, emotional, and financial impact on families. The process of navigating uncharted territory was characterized by four dimensions - entering unfamiliar territory, shifting priorities, creating meaning, and holding the fort. Parents used strategies within these dimensions to manage the physical, cognitive, and emotional work arising from the situation. These dimensions and strategies were constrained and facilitated by four intervening conditions - relationships with health care providers, availability of information, gender differences, and communication between parents. The theory generated in this study contributes to an understanding of families' experiences as they live with a dying child. This theory provides a framework from which appropriate, family-centred interventions can be developed to facilitate optimal palliative care.

description: During the past century, large hydraulic infrastructures have been considered as the most effective tools for increasing water supply and rationalise water management. According to this approach, large infrastructures are seen as catalysts for territorial development and economic progress. More recently, international surveys of results of water supply policies and performances of large dams, show that these structures need to be integrated in more comprehensive Integrated Water Resource Management strategies at catchments' scale, to promote equitable and sustainable regional development. The aim of this communication is to present the role of large hydraulic infrastructures within the regional development dynamics with particular attention to the Sebou basin in Morocco, in order to assess some relevant impacts on local communities and their ecosystems. The Sebou region is one of the most important basins in Morocco, in the context of the national strategies and policies of management of water resources, established by the Water Law of 1995. The development of hydraulic infrastructures in the Sebou Basin begun in 1935, with construction of a complex of ten large dams and nine small dams, to provide water for agriculture, domestic and industrial use, and to generate hydropower and control floods, in line with the national water policies that, from the 1960s onwards, looked at large dams as core infrastructures for regional development. A critical view will be given about the coherence of this strategy with the sustainability principles.

 Diagnosis and remarks. This rare species is assessed as Data Deficient in the IUCN Red List, as despite being recently collected in 2011, little is known about its distribution and preferred habitats, pending further collections to determine its actual conservation state (Vilela & Guillermo-Ferreira 2021k). The following character combination distinguishes this species from the remainder of Group A species: posterior margin of upper plate straight (Fig. 63c), upper plate concave at its middle (Fig. 63d); ML apex squared (Figs. 63c–d).

Tourism Specialization and Sustainability: A Long-Run Policy Analysis

description: This study focuses on the dynamic evolution of a small open economy specialized in tourism based on natural resources when tourist services are supplied to foreign tourists who are crowding-averse and give positive value to the environmental quality. We analyse the steady-state properties and run several policy exercises in two versions of our model: in the first, private agents' income is spent entirely on consumption while, in the second, agents are allowed to invest part of their income in pollution abatement technology (PAT) which artificially increases the rate of regeneration of the environmental asset. A unique locally saddle point equilibrium is found in both versions and for both the market and the centralized solution. Our main findings are that: 1) a corrective income tax raises steady state utility in both versions but is capable of leading the economy in its first-best dynamic path only when agents cannot invest in the PAT; 2) when the PAT is available to the government but not to agents, an income tax which finances abatement expenditures may increase steady state utility with respect to the market solution when the natural regeneration rate of the environment and the degree of crowding-aversion are both low enough; 3) when PAT is available, the market chooses to devote a higher fraction of income to abatement than the central planner but in both cases this fraction is positive only if the natural rate of regeneration is not too large; 4) when PAT is available an income pollution tax does not affect the dynamic path of the market economy.
Excitations of isolated static charges in the charge $q=2$ abelian Higgs model

description: We present lattice Monte Carlo evidence of stable excitations of isolated static charges in the Higgs phase of the charge $q=2$ abelian Higgs model. These localized excitations are excited states of the interacting fields surrounding the static charges. Since the $q=2$ abelian Higgs model is a relativistic version of the Landau-Ginzburg effective action of a superconductor, we conjecture that excited states of this kind might be relevant in a condensed matter context. Taken together with recent related work in SU(3) gauge Higgs theory, our result suggests that a massive fermion excitation spectrum may be a general feature of gauge Higgs theories.

description: We delve into the properties possessed by algebras, which we have termed seeds, that map to big Cohen-Macaulay algebras. We will show that over a complete local domain of positive characteristic any two big Cohen-Macaulay algebras map to a common big Cohen-Macaulay algebra. We will also strengthen Hochster and Huneke's "weakly functorial" existence result for big Cohen-Macaulay algebras by showing that the seed property is stable under base change between complete local domains of positive characteristic. We also show that every seed over a positive characteristic local ring (R,m) maps to a big Cohen-Macaulay R-algebra that is an absolutely integrally closed, m-adically separated, quasilocal domain.
