The community of Barrow, Alaska, Alaska has experienced coastal flooding during extreme weather events throughout events in the past 60 years. To improve the predictions of coastal flooding in coastal communities worldwide, models have been used to simulate flooding caused by storm surges. In many cases the coastal flood heights simulated by these coastal flooding models have been less than the flood heights that have been observed by the affected communities. The hypothesis for this project is that the results from coastal flooding models would be closer to observations if the contributions of waves to local sea level rise were taken into account. The Simulating Waves Nearshore (SWAN) model was used to simulate wave heights and directions offshore and in the Barrow coastal vicinity. Wind conditions from 11 historical storms and a recent storm (July 2003) were used as input data for SWAN. The wave simulations for the 11 historical storms showed wave development as a response to a constant wind speed and direction. The wave simulations for the July 2003 storm showed wave development as a response to the average wind speeds and directions every 6 hours. The output data for all the wave simulations consisted of wave height and direction distributions offshore and in the Barrow coastal vicinity. The resulting wave height data compared quite well to community recollections of the coastal wave heights. In a future application, these wave heights will be incorporated into coastal flooding models to test the contribution of waves to coastal flooding in Barrow.

Do Bonus Payments Enhance Agri-environmental Payments? Empirical Findings from Rice Farming in Japan

description: Agri-environmental payments (AEP) have been implemented for more than ten years and considered as a primary agri-enviromental policy in Japan. However, program enrollment is close to its peak due partly to budget limitation and rigid payment scheme. It might be possible to increase program participation by introducing some flexible payment schemes. This study investigates the effects of different bonus (extra payment) payments on farmers acceptance decisions of the AEP in Japan. To achieve this objective, we conducted a survey for 576 rice farmers in four prefectures (Akita, Fukui, Shiga, and Shimane). We introduced three hypothetical bonus payments (scale, acquisition, and adjacency) and asked farmers about their possible acceptance. Farmers responses were then used to derive their minimum acceptable bonus levels. Our results show that farmers are quite responsive to scale and adjacency bonus payments, but not to acquisition bonus. Our results also show that there is significant variation in minimum acceptable bonus, reflecting considerable heterogeneity among farmers in the study region. Using these estimated results, Japan s AEP would attract more farmers and achieve significant efficiency gain without substantial budget increase. Acknowledgement :

description: We calculate the modification of the effective interaction of particles on the Fermi surface due to polarization contributions, with particular attention to spin-dependent forces. In addition to the standard spin-spin, tensor and spin-orbit forces, spin non-conserving effective interactions are induced by screening in the particle-hole channels. Furthermore, a novel long-wavelength tensor force is generated. We compute the polarization contributions to second order in the low-momentum interaction V_{low k} and find that the medium-induced spin-orbit interaction leads to a reduction of the 3P2 pairing gap for neutrons in the interior of neutron stars.

description: The technology now exists that enables educators to conduct mathematics and statistics tutoring online, that is, via the Internet. In fact, several universities, as well as many private firms, are beginning to offer such tutoring. What are the drawbacks and/or limitations of online tutoring? Are there barriers, either technical or psychological, that must be overcome in order to be effective? These types of questions motivated this qualitative feasibility case study. The study sought to explore the OT environment, in an effort to help determine its merits and drawbacks. Experienced collegiate mathematics and statistics tutors were paired with college mathematics and statistics students for the study. The pairs met for three face-to-face tutoring (FT) sessions, alternating with three online tutoring (OT) sessions during the course of a semester. The OT sessions involved the use of computers outfitted with Aiptek's HyperMeeting, a $100 system that included a digital notepad, web-cam, and a headset, along with the necessary software. Participants used a whiteboard, which allowed their communications to be seen by one another simultaneously. Results of the study indicate that OT can be effective. However, less material was covered in OT than in FT. Reasons for this difference included both technical considerations, as well as psychological issues. Participants experienced failures of the technology employed, including disconnections and audio problems. Such factors as inaudible audio and illegible writing also contributed to higher levels of confusion and more frequent mathematical mistakes in OT than in FT. The lack of a shared field of vision for separated participants also slowed the process considerably. It was observed that the ability of a tutor to read the facial and body language cues of the tutee was hampered by the medium, and that this often led to difficulty in ascertaining precisely where a tutee was in the learning process. The majority of the participants reported enjoying OT, but being frustrated at times with the technical difficulties they encountered. Those with higher levels of mathematics and technology anxiety were also those less satisfied with the OT experience. Participants also reported a loss of the sense of connection during OT sessions.

description: This paper examines Chinese public attitudes toward GM labeling and evaluate the impact of public confidence in government management of GM food labeling on their attitudes. We collected data from 1730 respondents in 2015-16, including consumer, farmer, media and agricultural official in relevant agricultural department. The results show that different groups of people have different attitudes toward GM food labeling, and those who are more familiar with GMOs or who trust the government are more positive. They have different attitudes toward different ways of labeling as well. Most respondents prefer foods without labeling and foods labeled no GM ingredients. Our findings may contribute to provide a basis for GM food labeling policy establishment and promote development of GM foods in China. Acknowledgement :

description: The method of preparation and methods of analysis of a narrow distribution polystyrene of about 7000 mass units (u) used in an interlaboratory comparison of matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF-MS) of synthetic polymers is described. Size exclusion chromatography (SEC) was used to measure the polystyrene sample variability. Fourier transform infrared spectroscopy (FTIR) and MALDI-TOF-MS were used to analyze end groups on the polymer. The polystyrene was analyzed by MALDI-TOF-MS and classical methods of polymer characterization. The number (Mn) and mass (M w) average of the molecular mass distribution (MMD) determined by the classical methods (light scattering and NMR) were compared with those obtained by MALDI-TOF-MS. Agreement between classical methods to obtain the moments of the MMD and the MALDI is found to be good overall. However, all the experimental values obtained by MALDI fell below the classical values. The statistical analysis of the data from the interlaboratory comparison conducted by NIST, which includes data from 23 different laboratories, is discussed. Analysis of variance (ANOVA) is used to examine the influences of the independent parameters (laboratory, matrix, instrument manufacturer, and instrument mode) on the data. The parameters, laboratory and instrument manufacturer, were determined to have an influence on the MMD, where matrix was found not to have a significant influence. The MMD that is obtained in polymer characterization may be biased by preferential desorption/ionization of low mass polymer molecules, preferential ion attachment to larger polymers, or degradation and fragmentation due to the desorption process. In this paper the effect of the laser energy and the effect of the matrix on the MMD of four narrow synthetic polymers of varying thermal stabilities are studied. The four polymers considered were polystyrene (PS), polyethylene glycol (PEG), polymethyl methacrylate (PMMA), and polytetrahydrofuran (PTHF). Statistical analyses of the MMDs revealed that all of the moments of the four polymers were lower when run in 2,5-dihydroxybenzoic acid (DHB) than in all-trans retinoic acid (RA). PS did not appear to fragment as laser power increased, but PEG and PTHF clearly fragmented with increased laser power.

description: Abstract Iran accounts for more than 50 percent of the world pistachios market and thus has a leading role in price formation of pistachios. The objective of this study is to determine the price transmission pattern between domestic and world markets of pistachio and to investigate the link between market power and asymmetric adjustment. An innovative specification of asymmetric autoregressive model of Pricing to Market (PTM) employed to study the export-domestic price relationship by incorporating the exchange rate in increasing and decreasing components of the PTM model. Results indicate that PTM analysis-based specification is preferable to a simple model that does not cover the exchange rate effect. Also, the empirical findings suggest that export prices are more responding to the exchange rate increases than decrease in the exchange rates. The asymmetric transmission effect of the exchange rate also indicates a possible source of market power exerted by Iranian exporters Acknowledgement :

description: Market is the foundation of modern society. However, how did market evolve? Previous research has explored the impacts of spatial distance and transportation conditions on market integration. This paper argues that natural disasters also played a crucial role in the evolution of market integration in China, particularly in the grain market. When natural disasters occur, governments relief measures and merchants arbitrage activities will gradually promote interconnectivity among local grain markets. In this paper, China's major grain monthly price dataset from 1746-1795 and the Chinese historical disaster records dataset from 1696-1795 are used to analyze the impact of natural disasters on grain market integration. The empirical results show that natural disasters have a significantly positive effect on the integration of the grain market. The findings continue to hold after controlling the traffic conditions, grain varieties and lag effect. This study proposes a new perspective for understanding the evolution of the grain market.

description: Nutrition disorders in under-five children continue to be one of the most important development concerns for Malawi government and its development partners. Tackling such a crisis requires an initial understanding of its underlying drivers. This study therefore, examines the determinants of malnutrition in under-five children in Malawi using econometric based tools. We use 2010/2011 Malawi s Third Integrated Household Survey data. Three anthropometric indices are derived to establish child nutrition status and Logit model is used to examine the relationship between the nutrition status and the socioeconomic, institutional, and demographic characteristics of the children. About 11.4% were found to weight too little for their height (wasting), 30.6% were weighing too little for their age (underweight) and about 48% were too short for their age (stunted). The results establish evidence that nutrition status in under-five children is strongly associated with maternal education, location, water quality, growth monitoring, number of daily meals, dependency ratio and household size. The paper concludes by drawing the policy implications of the present findings. Acknowledgement :

We have measured the flux densities at 0.96, 2.3, 3.9, 7.7, 11.2 and 21.7 GHz in different sets, duration from a week to some months. In general there are 940 observations of SS433 and more than 4500 flux density measurements in the period. Observations show that radio spectra are well fitting by a power law. The mean spectral index remained the same, $-0.60\pm0.14$ during almost 20 years at least, and mean accuracy of the index determination was better than 0.1 in our multi-frequency observations, i.e. it was higher than in the intensive two-frequency monitoring of SS433 with the three-element GBI interferometer.

No-go Theorem of Purification

Year: 2020
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The Shannon's bound for compression is one of the key restrictions for the compression of quantum information. Here we show that the unitarity of the compression operation imposes new bounds on the compression that are more limiting than Shannon's compression bound. This translates to a no-go theorem for the purification of quantum states. For a specific case of a two-qubit system, our results indicate that it is not possible to distill purity beyond the maximum of the individual purities. We show that this restriction results in the cooling limit of the heat-bath algorithmic cooling techniques. We formalize the limitations imposed by the unitarity of the compression operation in two theorems and use the theorems to show that the limitations of unitarity lead to the cooling limit of heat-bath algorithmic cooling. To this end, we introduce a new optimal cooling technique and show that without the limitations of the unitary operations, the new cooling technique would have exceeded the limit of Heat-bath algorithmic cooling. This work opens up new avenues to understanding the limits of dynamic cooling.

description: We derive explicitly the structural properties of the $p$-adic special orthogonal groups in dimension three, for all primes $p$, and, along the way, the two-dimensional case. In particular, starting from the unique definite quadratic form in three dimensions (up to linear equivalence and rescaling), we show that every element of $SO(3)_p$ is a rotation around an axis. An important part of the analyis is the classification of all definite forms in two dimensions, yielding a description of the rotation subgroups around any fixed axis, which all turn out to be abelian and parametrised naturally by the projective line.
 Furthermore, we find that for odd primes $p$, the entire group $SO(3)_p$ admits a representation in terms of Cardano angles of rotations around the reference axes, in close analogy to the real orthogonal case. However, this works only for certain orderings of the product of rotations around the coordinate axes, depending on the prime; furthermore, there is no general Euler angle decomposition. For $p=2$, no Euler or Cardano decomposition exists.

Seasonal dependency of diurnal and semidiurnal surface wind variations over the tropical Pacific Ocean

Publisher: name: University Corporation For Atmospheric Research (UCAR)
Year: 2003

To advance our understanding of the behavior of the large-scale atmospheric circulation, the daily cycle of the near-surface wind field over the tropical Pacific Ocean was examined. Hourly wind measurements collected from 53 moored buoys in the Tropical Atmosphere Ocean array (9째N-8째S, 165째E-180째W) from 1993 through 2002 were used to document seasonal changes of the diurnal and semidiurnal harmonics of surface wind variability. The zonal wind component was dominated by a semidiurnal variation, with a near-uniform amplitude (~0.14 m/s) and phase (~0300 and 1500 local time) across the tropical Pacific. The semidiurnal cycle showed no apparent seasonal differences and was generally well explained by atmospheric thermal tidal theory. The meridional wind component, on the other hand, exhibited primarily diurnal variability (amplitudes ~0.17 m/s) with opposite phase on either side of the equator, particularly in the western Pacific (~0600-0900 local time in the northern hemisphere, 1800-2100 local time in the southern hemisphere). This induced a diurnal cycle of wind divergence near the equator, with enhanced convergence in the late evening. This diurnal cycle of surface wind divergence may contribute to the diurnal cycle in convection and rainfall observed near the equator. Some seasonal dependence was found in the diurnal meridional wind variations in the eastern equatorial Pacific, with stronger amplitudes during boreal summer and autumn.

description: The asset base, income and livelihood strategies of rural households in Zambia differ widely. For this reason, a one-size-fits-all strategy will not be effective. Therefore, there is need for empirical evidence of how different policy instruments in agriculture and social protection and combinations of these can be targeted to different population groups. This could also help orient public expenditure into more impactful and cost effective interventions in agriculture and social protection. Using Principal component analysis and Cluster analysis, Zambia s 1.4 million smallholder farming households fall into five broad livelihood groups. While crop and non-crop agriculture plays a dominant role in the livelihoods of most rural households, off-farm activities are also important. Poor rural households need both income and productive support, which can be provided through social protection and smallholder agricultural development programmes. Agricultural development programmes need to be adjusted to different crop and non-crop agricultural activities. Support also needs to be provided to off-farm income-generating activities. For the wealthiest clusters, policy should consider private sector led down and upstream agricultural supply and/or value chain inclusion and development.

The lowest part of the troposphere is called the planetary boundary layer (PBL). The depth of the PBL depends on the amount of solar heating and friction at the surface of the earth. These surface processes cause turbulence in the PBL, which initiates the growth of the PBL. This growth involves the lifting of moist air parcels, dust and aerosol particles and the sinking of dry parcels, thereby initiating the convection process. The purpose of this study was to validate the use of water vapor mixing ratio profile data from Goddard's Scanning Raman Lidar (SRL) and aerosol backscatter profile data from the Holographic Airborne Rotating Lidar Instrument Experiment (HARLIE lidar) to characterize PBL heights and evolution. These lidar-based PBL heights were compared with radiosonde based PBL heights for one case study from the International H₂O Project (IHOP): May 22, 2002. From the lidar backscatter profiles, the PBL heights were calculated using a wavelet analysis method. These lidar-based PBL heights were compared to virtual potential temperature derived PBL heights from radiosonde observations (temperature, pressure, and humidity). The results show that both lidars compared well with the radiosonde data. Both lidars overestimate the PBL heights, however, the SRL PBL height compared better with the radiosonde PBL heights than the HARLIE derived PBL heights. These results will be use in further studies to validate PBL heights obtained from PBL parameterizations.
The Land Rental Market in Thai Agriculture and Its Impact on Household Welfare

description: This study uses panel data from 384 Thai rural farm households collected annually from 2000-2013 to examine the determinants of household s land rental market participation, and the impacts of renting land on household incomes. A preliminary finding indicates that households with relatively poor land endowment cultivate more land than do other households to the extent that more than half of the land is rented in. Consistent with previous literature, the study find evidence that land rental markets in Thailand promote farm productivity and reduce landholdings inequality by transferring land from less-efficient to more-efficient households and from land-abundant to labor-constrained households, respectively. More importantly, the rental markets significantly raise the net farm incomes of tenants, most of whom are land-constrained households. Mechanisms to reduce land conflicts and remove local restrictions on land rental are needed in order to improve the functioning of land rental markets, and thereby enhancing farm income.

description: We generalize a classical result of Andrianov on the decomposition of Hecke polynomials. Let $\mathfrak{F}$ be a non-archimedean local fied. For every connected reductive group $\mathbf{G}$, we give a criterion for when a polynomial with coefficients in the spherical parahoric Hecke algebra of $\mathbf{G}(\mathfrak{F})$ decomposes over a parabolic Hecke algebra associated with a non-obtuse parabolic subgroup of $\mathbf{G}$. We classify the non-obtuse parabolics. This then shows that our decomposition theorem covers all the classical cases due to Andrianov and Gritsenko. We also obtain new cases when the relative root system of $\mathbf{G}$ contains factors of types $E_6$ or $E_7$.

description: The study analysed the technical efficiency of small-scale pigeon pea farms in Malawi. 2010/2012 National wide data of 2,137 pigeon pea farmers were analyzed using Maximum Likelihood estimation of a Stochastic frontier. The determinants of technical efficiency were incorporated within single-stage estimation of the frontier. Results revealed that the average output of pigeon pea farms in Malawi could increase by 47% under prevailing technology. The technical efficiency of the sampled pigeon pea farms ranged from 0.22 to 0.84 (0.53 average). Most importantly, the empirical results demonstrate that better extension services and farmer training programs on crop marketing and providing access to credit are key to enhance technical efficiency.

description: We derive an exact formula for the field form factor in the anyonic Lieb-Liniger model, valid for arbitrary values of the interaction $c$, anyonic parameter $κ$, and number of particles $N$. Analogously to the bosonic case, the form factor is expressed in terms of the determinant of a $N\times N$ matrix, whose elements are rational functions of the Bethe quasimomenta but explicitly depend on $κ$. The formula is efficient to evaluate, and provide an essential ingredient for several numerical and analytical calculations. Its derivation consists of three steps. First, we show that the anyonic form factor is equal to the bosonic one between two special off-shell Bethe states, in the standard Lieb-Liniger model. Second, we characterize its analytic properties and provide a set of conditions that uniquely specify it. Finally, we show that our determinant formula satisfies these conditions.

Democratizing the post -socialist media: A comparative study of television broadcasting policy in Bulgaria and Czech Republic, 1989--1999
Creators: name: Ivantcheva, Assia Lubomirova
Publisher: name: American University
Year: 2023

description: In 1989 most Central and East European (CEE) states began a challenging transition from socialist regimes to market democracies. An important part of this process has been the reconstruction of the state-controlled media into independent and pluralistic systems, which can ensure the meaningful exercise of civic information rights, such as the right to obtain information, to form and express opinions freely, and refine them in public discussions. The dissertation examines the ways in which media policy has protected and/or distorted these information rights in the post-socialist period. Television is singled out from other types of media because it remains the most popular source of information for the public in CEE, while its reform has been prolonged and widely contested. Theoretically, the analysis has been informed by Habermas's historical account of the public sphere as a space for reasoned and critical debate among citizens. The concept is re-considered in view of the complex process of post-socialist transformation, which includes the democratization of the state, the transition to market economy, and the revival of civil society. The revised concept is used as a tool for comparing and evaluating broadcasting policies in two countries---Bulgaria and Czechoslovakia/the Czech Republic between 1989 and 1999. While emphasizing the progress made in restoring basic information rights of citizens in these two cases, the dissertation still confirms the continuous trend of political interference, particularly characteristic of Bulgaria. Furthermore, the study situates the policy analysis within the broader context of democratization and concludes that the post-socialist state and the emerging market have at once enhanced and distorted the creation of the public sphere in both countries. The examination of the media policy, advocated by international organizations like the European Union and local civil society activists, shows that they have mostly contributed to the democratization of broadcasting policy, particularly in Bulgaria. However, the study of the Czech broadcasting reforms, including the complex Nova TV case, suggests that in the long run the aggressive pursuit of liberalization, in the absence of strong public-service guarantees, is likely to distort the emerging public sphere and incite civic response.

Evaluating an event-based approach to workflow services

Workflow management is crucial in monitoring and controlling business processes. Advancements have been made in computer-based workflow management, which allowed for the partial or complete automation of these processes. However, existing computer-based systems have not been successful in highly distributed domains. Hence, these domains have continued conducting their workflow management processes in an adhoc manner. Conducting workflow management in this way has three flaws: human dependency, confined knowledge, and inconsistency in tasks. Metis, an event-based workflow service, was developed to alleviate these flaws by bringing automation to workflow management in highly distributed domains, primarily digital libraries. This project conducted an evaluation of Metis using two data retrieval processes. Each workflow carried out via Metis soundness using a petri net analysis; in addition performance analysis was also conducted. Soundness tested Metis' ability to handle exceptions and/or errors that may occur. The performance analysis is a qualitative measurement based on two major metrics: quality and efficiency. This evaluation found that while Metis' approach is valid it needs further modification in areas requiring the automation of repetitive tasks such as multiple file transfers. Furthermore, the qualitative analysis showed an improvement in conducting workflow management using Metis versus in an adhoc manner.

description: We prove that Hensel minimal expansions of finitely ramified Henselian valued fields admit spherically complete immediate elementary extensions. More precisely, the version of Hensel minimality we use is $0$-hmix-minimality (which, in equi-characteristic $0$, amounts to $0$-h-minimality).
