description: Nuclear quantum effects (NQE) tend to generate delocalized molecular dynamics due to the inclusion of the zero point energy and its coupling with the anharmonicities in interatomic interactions. Here, we present evidence that NQE often enhance electronic interactions and, in turn, can result in dynamical molecular stabilization at finite temperature. The underlying physical mechanism promoted by NQE depends on the particular interaction under consideration. First, the effective reduction of interatomic distances between functional groups within a molecule can enhance the $n\toπ^*$ interaction by increasing the overlap between molecular orbitals or by strengthening electrostatic interactions between neighboring charge densities. Second, NQE can localize methyl rotors by temporarily changing molecular bond orders and leading to the emergence of localized transient rotor states. Third, for noncovalent van der Waals interactions the strengthening comes from the increase of the polarizability given the expanded average interatomic distances induced by NQE. The implications of these boosted interactions include counterintuitive hydroxyl--hydroxyl bonding, hindered methyl rotor dynamics, and molecular stiffening which generates smoother free-energy surfaces. Our findings yield new insights into the versatile role of nuclear quantum fluctuations in molecules and materials.

description: Workation ist ein neues Konzept im Rahmen von New Work, mit dem potenziell mobil Arbeitende die berufliche Tätigkeit mit einem Urlaub zeitweise kombinieren können. Aufgrund der jungen Entwicklung stellt sich die Frage nach dem langfristigen Potenzial von Workation und wie dieses von den verschiedenen Akteuren Arbeitnehmer, Arbeitgeber und dem Beherbergungssektor eingeschätzt wird. Durch eine umfassende Literaturrecherche und eine quantitative Befragung von Vertretern des Beherbergungssektors wurden die verschiedenen Perspektiven analysiert. Ziel dieser Arbeit war es insbesondere dem Tourismussektor, stellvertretend dem Beherbergungssektor, einen Mehrwert zu bieten. Die Ergebnisse verdeutlichen, dass langfristiges Potenzial gesehen wird und alle Akteure diverse Vorteile in Workation sehen. Somit kann geschlussfolgert werden, dass sich die Workationer zu einer für den Tourismussektor bedeutenden Zielgruppe entwickeln. Basierend auf diesen Erkenntnissen wurden konkrete Handlungsempfehlungen für den Beherbergungssektor formuliert, um die Zielgruppe optimal ansprechen zu können, wobei nicht jede Unterkunft aufgrund von externen Gegebenheiten wie der Lage oder Internetverbindung gleichermaßen vom Potenzial profitieren kann.

description: We present a new adaptive resolution technique for efficient particle-based multiscale molecular dynamics (MD) simulations. The presented approach is tailor-made for molecular systems where atomistic resolution is required only in spatially localized domains whereas a lower mesoscopic level of detail is sufficient for the rest of the system. Our method allows an on-the-fly interchange between a given molecule's atomic and coarse-grained level of description, enabling us to reach large length and time scales while spatially retaining atomistic details of the system. The new approach is tested on a model system of a liquid of tetrahedral molecules. The simulation box is divided into two regions: one containing only atomistically resolved tetrahedral molecules, the other containing only one particle coarse-grained spherical molecules. The molecules can freely move between the two regions while changing their level of resolution accordingly. The coarse-grained and the atomistically resolved systems have the same statistical properties at the same physical conditions.

description: In this paper we present the WeCAPP variable star catalogue towards the bulge of M31. The observations of the WeCAPP microlensing survey (optical R and I bands) during three years (2000-2003) result in a database with unprecedented time coverage for an extragalactic variable star study. We detect 23781 variable sources in a 16.1' x 16.6' field centered on the nucleus of M31. The catalogue of variable stars contains the positions, the periods and the variations in the R and I bands. We classify the variables according to their position in the R-band period-amplitude plane. Three groups can be distinguished; while the first two groups can be mainly associated with Cepheid-like variables (population I Cepheids in group I, type II Cepheids and RV Tauri stars in group II), the third one consists of Long Period Variables (LPVs). We detect 37 RV Tauri stars and 11 RV Tauri candidates which is one of the largest collections of this class of stars to date. The classification scheme is supported by Fourier decomposition of the light curves. Our data shows a correlation of the low-order Fourier coefficients Phi_21 with Phi_31 for classical Cepheids, as well for type II Cepheids and RV Tauri stars. Correlating our sample of variable stars with the X-ray based catalogues of Kaaret (2002) and Kong et al. (2002) results in 23 and 31 coincidences, 8 of which are M31 globular clusters. The number density of detected variables is clearly not symmetric, which has to be included in the calculations of the expected microlensing event rate towards M31. This asymmetry is due to the enhanced extinction in the spiral arms superimposed on the bulge of M31 which reduces the number of sources to about 60%, if compared to areas of equivalent bulge brightness (without enhanced extinction being present).

description: To reach climate protection goals, Germany aims to significantly reduce emissions through the heat transition. Providing renewable heat sources in urban areas presents one of the greatest challenges due to the limited space, yet high energy demand. This thesis addresses the issue by creating a workflow based on GIS (Geographic Information Systems) to quickly identify socalled “sub-areas” where low temperature (LowEx) district heating could be suitable. The heating concept shall connect sources of shallow geothermal energy within an observed area and enable a more effective distribution of heat. Photovoltaics (PV) on roofs as well as parking lots shall counter the increased power demand of the decentralized heat pumps. The workflow involves estimations of annual technical potentials and the identification of sub-areas using ArcGIS Pro, Polysun, and Earth Energy Designer. This was created based on and applied to the district of Neu-Schwachhausen. Bremen. Scenarios (S) of 2022, 2030, 2038-a, and 2038-b were observed, varying the availability of the selected technologies (borehole heat exchanger and PV) and the level of heat demand for space and water heating. The sub-areas were evaluated regarding overall quality based on selected criteria. Results show that such a concept of LowEx DH is the ideal heating strategy for the district if the circumstances in S-2038-b can be achieved. Most neighborhoods would be technically suitable, especially due to the 300 m deep boreholes and heat demand reductions. Considering the cumulated values, the required power for heat pumps could be covered by PV alone in many of the areas, underlining the necessity of efficient energy storage in reality. Solar parking lots have a less substantial impact overall compared to roof potentials, though a detailed feasibility study is recommended to confirm this. This thesis also shows the importance of sharing local sources between neighborhoods, in addition to using large sports fields, to efficiently maximize area usage. Prioritizing these elements would lead to higher energy self-sufficiency in the subareas. In further research, the workflow can be extended by adding an economic parameter, seasonal fluctuations, and improved automation.
Uniqueness of STFT phase retrieval for bandlimited functions

description: We consider the problem of phase retrieval from magnitudes of short-time Fourier transform (STFT) measurements. It is well-known that signals are uniquely determined (up to global phase) by their STFT magnitude when the underlying window has an ambiguity function that is nowhere vanishing. It is less clear, however, what can be said in terms of unique phase-retrievability when the ambiguity function of the underlying window vanishes on some of the time-frequency plane. In this short note, we demonstrate that by considering signals in Paley-Wiener spaces, it is possible to prove new uniqueness results for STFT phase retrieval. Among those, we establish a first uniqueness theorem for STFT phase retrieval from magnitude-only samples in a real-valued setting.

Publisher: name: International Quarterly for Asian Studies
Year: 2024

description: Over the past decade, during the tenure of President Joko Widodo, West Papua has undergone a process that Jason and Michael (2019) describe as a “recurring frontier”, whereby frontiers emerge, evolve and are continually redefined. The situation there is exemplified by a number of intertwined “frontier indicators”, which in this article are focused on military threats, the corrupt bureaucracy surrounding infrastructure and the environmental disasters of deforestation and flooding. The paper is based on reflections from fieldwork in Sorong greater area (Sorong Raya) between 2019 and 2023. It indicates several developments occurring at the micro level in Sorong including the history of threats and violence that have created frontiers and overlapping bureaucratic governance, resulting in urban environmental degradation. The creation of frontiers for Papuans is not only currently underway but is also envisioned as a future project to be developed across Papua. Reflecting on this specific case in Sorong, West Papua, it is anticipated that frontier areas will emerge throughout Papua in the future.

description: The in-medium behavior of ground-state $q\bar{q}$ mesons, where $q \in \{u,d,s,c\}$, in vector and axial-vector channels is studied based on the spectral analysis for mesonic correlators at finite temperature and zero chemical potential. We first compute the correlators by solving the quark gap equations and the inhomogeneous Bethe-Salpeter equations in the rainbow-ladder approximation. Using a phenomenological ansatz, the spectral functions are extracted by fitting the correlators. By analyzing the evolution of the spectral functions with the temperature, we obtain the dissociation temperatures of mesons and discuss their relations to the critical temperature of the chiral symmetry restoration. The results show a pattern of the flavor dependence of the thermal dissociation of the mesons.

Rural Social Movements and Popular Struggles under Jokowi’s Presidency
Creators: name: Anugrah, Iqra
Publisher: name: International Quarterly for Asian Studies
Year: 2024

description: The victory of Joko Widodo in the 2014 presidential election and the early phase of his first-term presidency brought some hope to Indonesian rural social movements. However, the structural constraints under oligarchic politics, the elite jockeying surrounding Jokowi, and the president’s lack of willingness to support an agrarian justice agenda rendered the movements’ strategy of intervention by state institutions and policies ineffective. This tension persuaded some sections of rural communities and activists to pursue a more contestational approach in advocating their rights, especially during Jokowi’s second term (2019–2024). This article examines the prevalence of the logic of concessionary capitalism in Jokowi’s rural policies, its devastating impacts on rural communities and the creative, sometimes impromptu, responses of rural social movements to dispossession and marginalisation. It also analyses the limits and gains made by the movements’ actors and provides an overall assessment of state-rural social movement relations under Jokowi’s presidency and the Covid-19 pandemic.

description: Double-peaked Balmer lines have been observed in about 150 AGNs and were interpreted preferably as emission from relativistic accretion disks. In this paper, we report the discovery of extreme double-peaked lines in SDSS J0942+0900 and SDSS J1417+6141. The FWHM of the Halpha line ~40,600 km/s in the first object is almost twice as large as the broadest one previously known. By comparing the line profile with accretion disk models, we find that most of the line flux is emitted from a narrow annulus around 100Rg in SDSS J0942+0900, and from a disk of radii between 100 and 400Rg in SDSS J1417+6141. This is the first time that an accretion disk at radii below 100Rg can be directly probed through optical emission lines. A certain asymmetry in the disk is required for both objects. Another much weaker broad Halpha component (EW~20A, and FWHM 4000km/s) is also detected in both objects. Both objects show weak radio emission and strong high-ionization narrow lines.

description: The Beaufort Sea offshore Northern Canada is an Arctic region that has continuously gained the attention of private and governmental organizations due to its potential for future developments in mineral resource extraction, climatic modification forecasts, opening of navigation routes and several other matters of geopolitical, economic and scientific importance. Currently experiencing notable changes resulting from the warming associated with Holocene sea level rise, the Beaufort Shelf is still accommodating a thermal pulse of about 10°C that has been propagating since the last marine transgression, in which relatively warm waters flooded areas of permafrost occurrence. The harmonization of this thermal contrast creates circumstances where gas hydrates and permafrost can become destabilized, which in turn potentially undermines slope stability. Additionally to the warming rooted on the glacial-interglacial cycle, the broadly accredited present tendencies of anthropogenic climatic change are deemed of sufficient magnitude to be relevant in the problematic here examined. Though many sources of geohazards are at play in this region, this study focuses on the effects of temperature-induced gas hydrate dissociation and permafrost thawing in prompting mass wasting events. Through a number of computational steps based on empirical data and experiments on samples acquired during scientific research expeditions, it is reckoned that rather modest sediment temperature variations are sufficient to cause slope failure at the Beaufort Shelf and Slope.

description: The magnetic phase diagram for antiferro-quadrupole (AFQ) ordering in tetragonal HoB$_2$C$_2$ has been investigated by measurements of elastic constants $C_{11}$, $C_{44}$ and $C_{66}$ in fields along the basal $x$-$y$ plane as well as the principal [001]-axis. The hybrid magnet (GAMA) in Tsukuba Magnetic Laboratory was employed for high field measurements up to 30 T. The AFQ phase is no longer observed above 26.3 T along the principal [001] axis in contrast to the relatively small critical field of 3.9 T in fields applied along the basal [110] axis. The quadrupolar intersite interaction of $O_{xy}$ and/or $O_2^2$ is consistent with the anisotropy in the magnetic phase diagram of the AFQ phase in HoB$_2$C$_2$.

description: Die Wärmewende ist ein zentraler Baustein für das Erfüllen von Klimaschutzzielen. In diesem Zusammenhang stellt die Rückgewinnung und Nutzung von in Abwasser enthaltener Wärmeenergie eine emissionsfreie und erneuerbare Technologie zur Wärmeerzeugung und -versorgung dar. Sie verfügt über ein enormes energetisches Potential, das bisher weitestgehend ungenutzt bleibt. Aufgrund komplexer Zusammenhänge zwischen Entwässerungssystemen und Wärmeversorgungsanlagen ist vor allem die Standortfrage eine wichtige. An dieser Stelle etabliert sich die vorliegende Arbeit mit ihrer zentralen Forschungsfrage: Wo ist die Installation einer Anlage zur Rückgewinnung und Nutzung von Abwasserwärme in der Stadt Bremen energetisch und strategisch sinnvoll? Dabei verfolgt die Arbeit eine Standortsuche nach einer im Merkblatt DWA-M 114 antizipierten integralen Vorgehensweise. Auf der Basis eines theoretischen Grundlagenteils wird ein Modellansatz erarbeitet. Dieser ist die Voraussetzung zu einer qualitativen Raumanalyse zur Standortsuche für Anlagen der Abwasserwärmerückgewinnung (AWRG) bzw. Abwasserwärmenutzung (AWN). Als räumlich dedizierte Nutzwertanalyse liefert sie zudem für jeden grundsätzlich geeigneten Standort einen Eignungsgrad in Form von festgelegten Potentialklassen. Zu diesem Zweck werden Parameter definiert, die eine fördernde oder hemmende Einflussnahme auf die Standorteignung für AWRG- bzw. AWN-Anlagen haben. Die Akquise von Geodaten wird über verschiedene Institutionen ermöglicht. Als georeferenzierte Rohdaten haben sie in der räumlichen Ebene gegenseitige Beziehungen, die innerhalb geographischer Informationssysteme (GIS) miteinander verknüpft werden können. Dazu werden die Werkzeuge der freien Software QGIS genutzt. Die Raumanalyse führt zu u.a. als Kartenmaterial visualisierten Ergebnissen, die für Anlagen der AWRG und AWN geeignete Haltungen und Gebäude in der Stadt Bremen darlegen. In einer Ergebnisbewertung und Methodenevaluierung zeigt sich, dass die Untersuchungsergebnisse kohärent und die intendierten Prozessschritte des Modellansatzes grundsätzlich funktionsfähig sind. Eine Erweiterung des Modellansatzes mit zusätzlichen Datensätzen ist zu empfehlen. Darüber hinaus erlauben verschiedene Stellschrauben individuelle Anpassungen des Modellansatzes ohne übermäßigen Aufwand.

description: We present a detailed investigation of the probability density function (PDF) of order parameter fluctuations in the finite two-dimensional XY (2dXY) model. In the low temperature critical phase of this model, the PDF approaches a universal non-Gaussian limit distribution in the limit T-->0. Our analysis resolves the question of temperature dependence of the PDF in this regime, for which conflicting results have been reported. We show analytically that a weak temperature dependence results from the inclusion of multiple loop graphs in a previously-derived graphical expansion. This is confirmed by numerical simulations on two controlled approximations to the 2dXY model: the Harmonic and ``Harmonic XY'' models. The Harmonic model has no Kosterlitz-Thouless-Berezinskii (KTB) transition and the PDF becomes progressively less skewed with increasing temperature until it closely approximates a Gaussian function above T ~ 4π. Near to that temperature we find some evidence of a phase transition, although our observations appear to exclude a thermodynamic singularity.

description: Particle physics experiments in the United States and Asia have greatly contributed to the understanding of elementary particles and their interactions. With the recent discovery of the Higgs boson at CERN, interest in the development of next-generation colliders has been rekindled. A linear electron-positron collider in Japan and a circular collider in China have been proposed for precision studies of the Higgs boson. In addition to the Higgs programme, new accelerator-based long-baseline neutrino mega-facilities are being built in the United States and Japan. Here, we outline the present status of key particle physics programmes at accelerators and future plans in the United States and Asia that largely complement approaches being explored in the European Strategy for Particle Physics Update. We encourage the pursuit of this global approach, reaching beyond regional boundaries for optimized development and operations of major accelerator facilities worldwide, to ensure active and productive future of the field.

Conceptual Modeling of Time for Computational Ontologies

description: To provide a foundation for conceptual modeling, ontologies have been introduced to specify the entities, the existences of which are acknowledged in the model. Ontologies are essential components as mechanisms to model a portion of reality in software engineering. In this context, a model refers to a description of objects and processes that populate a system. Developing such a description constrains and directs the design, development, and use of the corresponding system, thus avoiding such difficulties as conflicts and lack of a common understanding. In this cross-area research between modeling and ontology, there has been a growing interest in the development and use of domain ontologies (e.g., Resource Description Framework, Ontology Web Language). This paper contributes to the establishment of a broad ontological foundation for conceptual modeling in a specific domain through proposing a workable ontology (abbreviated as TM). A TM is a one-category ontology called a thimac (things/machines) that is used to elaborate the design and analysis of ontological presumptions. The focus of the study is on such notions as change, event, and time. Several current ontological difficulties are reviewed and remodeled in the TM. TM modeling is also contrasted with time representation in SysML. The results demonstrate that a TM is a useful tool for addressing these ontological problems.

description: Novel formulations of nanocomposites derived from ZnO nanoparticles have provided potential biomedical applications as a new strategy for treatment of breast cancer. In this research, two types of ZnO nanomaterials were synthesized by sol–gel hydrothermal process and co-precipitation containing fast quenching and also surface modification methods. The cytotoxic effects on growth of the breast cancer cell lines MCF-7 were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. Cell viability of the breast cancer cell line MCF-7 was reduced with increasing ZnO nanofluid concentrations at 48 and 72 h of treatment. The IC50 value of MCF-7 cells after 72 h of treatment with the first product ZnO (a) and second one ZnO (c) were measured as 51.02 and 48.63 μg/ml, respectively (P < 0.05).

description: The infrared spectrograph GNIRS on Gemini South unlocks new possibilities to study the central black holes in dusty galaxies that have been inaccessible to previous black hole studies. We exploit good near-infrared seeing to measure the central black hole (BH) of Centaurus A (NGC 5128). We measure the stellar kinematics of NGC 5128 using the region around the CO bandheads at 2.3 microns and determine the black hole mass using orbit-based models. Black holes are believed to be essential components of galaxies, and their evolutionary states appear to be closely linked to those of their hosts. Our current knowledge does not go much beyond this; galaxies such as NGC 5128 (an AGN and recent merger) can further develop this knowledge. However, NGC 5128 and galaxies like it contain large amounts of dust which hamper optical spectroscopy, making near-infrared measurements an attractive alternative. We find a BH mass of 2.4e8 solar masses for an edge-on model, 1.8e8 solar masses for a model with inclination of 45 degrees, and 1.5e8 solar masses for a model with inclination of 20 degrees. We adopt the value for the edge-on model, which has significantly lower chi^2. These estimates are consistent with a previous gas dynamical estimate and are five to ten times higher than that predicted by the correlation between BH mass and velocity dispersion. If NGC 5128 will eventually follow the trend for quiescent galaxies, this result suggests that its BH assembled first before its host component. NGC 5128 thus provides an important example for our knowledge of central black holes; this technique can be applied to other such galaxies to further explore this question.

Ecological mechanisms in species origins : divergent natural selection and the evolution of reproductive isolation between sympatric sticklebacks
Creators: name: Rundle, Howard Douglas
Publisher: name: University of British Columbia
Year: 2009

description: Under the ecological model of speciation, reproductive isolation arises ultimately as a result of divergent natural selection. Laboratory experiments have demonstrated the feasibility of this mechanism but evidence from nature is lacking. This thesis investigates the role of ecological mechanisms in the origin of morphologically and ecologically distinct sympatric species-pairs of threespine sticklebacks (Gasterosteus aculeatus complex) that inhabit a few post-glacial lakes in southwestern British Columbia. Ecological speciation predicts that the fitness of hybrids should depend on their ecological context. This can be tested using reciprocal transplant experiments, provided the contribution of any genetic incompatibilities is controlled. I develop a quantitative genetic model to determine whether this is possible. Analysis of the model reveals that it is, and the experimental design involves the use of both hybrid backcrosses. I employ this design in a reciprocal transplant experiment in nature using the stickleback species-pairs. Results reveal a striking pattern of ecological-dependence: in each habitat the backcross more similar to the native parent species grew at approximately twice the rate of the other. Thus ecological mechanisms have been central to the evolution of postmating isolation between these stickleback species. Ecological speciation also predicts that reproductive isolation among populations should be correlated with environmental differences. To test this prediction I conducted laboratory mating trials using the stickleback species-pairs from three lakes. Results support the prediction, demonstrating that populations that evolved under different ecological conditions show strong premating isolation, whereas populations that independently evolved under similar ecological conditions lack isolation. Such parallel evolution of premating isolation, in correlation with environmental differences, strongly implicates divergent selection in the evolution of these species-pairs. Finally, I address the mechanisms responsible for divergent natural selection in the evolution of these species-pairs, focussing on the role of ecological interactions between populations. I use a pond experiment to test the combined effect of predation and competition on the strength of divergent selection.on a target population. Results suggest a strong interaction: the competition treatment generated divergent selection on the target population only under high predation conditions. This suggests that the ecological mechanisms responsible for the evolution of the species-pairs include both competition and predation.

description: In the following bachelor thesis, the missing Bitcoin adoption in Germany will be addressed. As a relatively low adoption of Bitcoin in Germany can be observed, the factors for missing adoption will be analyzed. The research question for the thesis is “What are the factors for missing Bitcoin adoption in Germany using the example of alumni at the Faculty of Economics at the University of Applied Sciences in Bremen?” and the formulated hypothesis is “Lack of knowledge is a major factor for missing Bitcoin adoption in Germany using the example of alumni at the Faculty of Economics at the University of Applied Sciences in Bremen.” Through applying the Diffusion of Innovations Theory by Rogers and the underlying frameworks on Bitcoin, the factors for missing Bitcoin adoption are examined. A focus on user’s adoption is set as individual decisions are eventually also a key factor in determining business decisions. In addition, a survey has been conducted by targeting alumni from the Faculty of Economics at the University of Applied Sciences Bremen in order to have a relatively highly-educated and well-earning group of participants. Consequently, the adoption rate among participants and the factors for an adoption or non-adoption are analyzed. The correlation between knowledge and ownership is then of special interest. The results show that lack of knowledge is a major factor for missing Bitcoin adoption in Germany, however, this is exacerbated by circumstances and external factors, which do not favor the reaching of the critical mass and the engagement in knowledge-seeking activities by users.

description: The energy of electron Fermi sea perturbed by external potential, represented as energy anomaly which accounts for the contribution of the deep-lying states, is analyzed for massive d = 1+1 Dirac fermions on a circle. The anomaly is a universal function of the applied field, and is related to known field-theoretic anomalies. We express transverse polarizability of Carbon nanotubes via the anomaly, in a way which exhibits the universality and scale-invariance of the response dominated by pi-electrons and qualitatively different from that of dielectric and conducting shells. Electron band transformation in a strong-field effect regime is predicted.

description: In this study, a stereometric analysis of the three-dimensional (3-D) surfaces of the Ag/diamond-like carbon (DLC) nanocomposite films was done. The nanocomposite thin films were fabricated by Radio Frequency Plasma-Enhanced Chemical Vapour Deposition (RF-PECVD). The 3-D surface microtexture was studied by high-resolution Atomic Force Microscopy (AFM) records combined with statistical analyses. More detailed information about surface statistical parameters and topographic features of analyzed samples were performed. The statistical parameters relating to the segmented motifs consistent with ISO 25178-2: 2012 have been generated using MountainsMap® Premium software. The analysis was performed by modeling Ag/DLC nanocomposite surface microtexture based on motif analysis (detection of essential characteristics in terms of surface dimensions, volume, curvature, shape) to be included in computer interactive simulation algorithms.

description: In recent papers the convexity of quasiarithmetic means was characterized under twice differentiability assumptions. One of the main goals of this paper is to show that the convexity or concavity of a quasiarithmetic mean implies the the twice continuous differentiability of its generator. As a consequence of this result, we can characterize those quasiarithmetic means which admit a lower convex and upper concave quasiarithmetic envelop.

description: Unilateral liberalization of U.S. peanut policy was evaluated using a model of U.S. and world peanut supply and demand. Under the proposed policy, world peanut price would rise slightly to $.20 per pound at the U.S. farm level. U.S. production would decline by 578 million pounds per year and would be offset by imports of 582 million pounds. U.S. net farm income would fall by $405 million per year. Lost income per farm would be $21,000 per year while the average outlay of consumers would decrease by $.84 per person at farm level price. Government expenditures would be virtually unchanged because of the market orientation of current policy.
