description: Wheat types may be classified according to strength, a baking characteristic. Since the demand for wheat is derived demand, the baking characteristic is directly related to end use. Accordingly, the wheat classes that are used in this study are divided into sub-groups according to strength, that is, strong, medium, and weak wheats. Time-series methods are employed to determine how the different classes of wheats are related within each sub-group. The different wheats under the different sub-groups are found to be substitutes to various degrees, but form a robust cointegrating relationship, implying that the wheat prices in these markets are bound together by a long-term equilibrium relationship. Within each of the sub-groups, the U.S. wheats were found to act as a price leader, driving the prices of other wheats belonging in the same sub-group. These U.S. wheats were found to form no long-run relationship between each other given their distinct end uses. The study highlights the importance of differentiating wheat by end use to specify price linkages more accurately.

Subjects: SECS-P/01 Economia politica

description: In this paper, we investigate the profitability of horizontal mergers of firms with price adjustments. We take a differential game approach and both the open-loop as well as the closed-loop equlibria are considered. We show that the merger incentive is determined by how fast the price adapts to the equilibrium level.

description: We explore the prospect of producing primordial black holes around the solar mass region during an early matter domination epoch. The early matter-dominated epoch can arise when a moduli field comes to dominate the energy density of the Universe prior to big bang nucleosynthesis. The absence of radiation pressure during a matter-dominated epoch enhances primordial black hole formation from the gravitational collapse of primordial density fluctuations. In particular, we find that primordial black holes are produced in the $0.1-10~M_{\odot}$ mass range with a favorable choice of parameters in the theory. However, they cannot explain all of the merger events detected by the LIGO/Virgo gravitational wave search. In such a case, primordial black holes form about $4\%$ of the total dark matter abundance, of which $95\%$ belongs to the LIGO/Virgo consistent mass range. The rest of the dark matter could be in the form of particles that are produced from the decay of the moduli field during reheating.

Subjects: SECS-P/01 Economia politica

description: In this paper, we develop a two-country world differential game model with a polluting firm in each country where there is transportation cost to investigate the equilibrium of the game between firms when they decide to trade or not and to see under which conditions social welfare coincides with the market equilibrium. We find out that in the static game bilateral trade is always the equilibrium for any acceptable transportation cost while in the dynamic game social planner can prevent the inefficient outcome by imposing and determining the proper amount of Pigouvian taxation.

description: This study analyzes U.S. consumers' choice of cornflakes under five different labeling statements. Using a nationwide survey and choice modeling framework, results indicate that consumers value labeling statements differently, depending on the information contained on the label. The random parameter logit model results indicated that, compared to cornflakes that have no label information, cornflakes labeled "contains no genetically modified corn" have a value of 10 percent more, the label "USDA approved genetically modified corn" has a value of 5 percent more, and the label "corn genetically modified to reduce pesticide residues in your food" has a value of 5 percent more. The results also suggest that consumers negatively valued the label "contains genetically modified corn," paying 6.5 percent less, and the label "may contain genetically modified corn," paying 1 percent less than the product that has no label information.
Work organization factors and musculoskeletal symptoms and claims among health care workers
Creators: name: Koehoorn, Mieke
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation is a study of health care workers and the relationship between work organization factors and work-related musculoskeletal outcomes. It was hypothesized that rates of upper-body and lower-body musculoskeletal symptoms and compensation claims would increase with exposure to adverse work organization factors defined by low job control, low work support, high job demands or time pressures, and high levels of workload, while controlling for individual and biomechanical risk factors. Theoretically, both models of work-related musculoskeletal morbidity and job stress informed the study. Musculoskeletal morbidity is believed to develop when the conditions of work exceed the capacity of the worker. These conditions may be the result of adverse work organization factors that produce a stress response among workers with a direct effect on the musculoskeletal system, or they may modify other workplace factors that in turn influence musculoskeletal conditions. The study employed a retrospective, longitudinal cohort design and followed 4020 health care workers from an acute-care hospital over a four-year period. Workers were enumerated from hospital personnel records and outcome data were ascertained from the hospital's occupational health and safety database. Biomechanical scores for occupations were assessed by direct observation and scored using checklists. Scores for the work organization measures of control, demands, support and pressure were assigned to cohort members using a job exposure matrix. The matrix was developed from responses to validated scales included in three random sample surveys of employees over the four-year study period. Workload measures were defined by time-varying levels of departmental sicktime, overtime and work units, calculated from financial reports. The risk of musculoskeletal symptoms and claims associated with work organization factors, controlling for individual and biomechanical factors, was assessed using Poisson regression. In the final models, low levels of job control and work support, as well as high levels of workload related to departmental sicktime, were significantly associated with an elevated risk of upper-body musculoskeletal symptoms and claims. The risk of lower-body musculoskeletal symptoms and claims was significantly elevated for workload due to high levels of departmental sicktime, and that for lower-body compensation claims with low job control. Individual and biomechanical factors were also significant predictors of musculoskeletal outcomes, which gives support to the idea that these outcomes have a multi-factorial etiology.

description: An unmanned aircraft system (UAS) consists of an unmanned aerial vehicle (UAV) and its controller which use radios to communicate. While the remote controller (RC) is traditionally operated by a person who is maintaining visual line of sight with the UAV it controls, the trend is moving towards long-range control and autonomous operation. To enable this, reliable and widely available wireless connectivity is needed because it is the only way to manually control a UAV or take control of an autonomous UAV flight. This article surveys the ongoing Third Generation Partnership Project (3GPP) standardization activities for enabling networked UASs. In particular, we present the requirements, envisaged architecture and services to be offered to/by UAVs and RCs, which will communicate with one another, with the UAS Traffic Management (UTM), and with other users through cellular networks. Critical research directions relate to security and spectrum coexistence, among others. We identify major R\&D platforms that will drive the standardization of cellular communications networks and applications.

The Influence of Role Models on Immigrant Self-Employment:
A Spatial Analysis for Switzerland

Publisher: name: Alma Mater Studiorum - Università di Bologna

Subjects: SECS-P/02 Politica economica

description: Theoretical and empirical research suggests a connection between the presence of role models and the emergence of entrepreneurs. Existing entrepreneurs may act as role models for self-employment candidates by providing successful examples. By explicitly considering the self-employment rates of the natives, which may influence locally the decisions of immigrants towards entrepreneurship, we develop a simple model that explains immigrant self-employment rates for a sample of 2,490 Swiss municipalities. In addition, we accommodate for the presence of spatial spillovers in the distribution of rates, and test a spatial autoregressive model which takes into account the average self-employment rates of immigrants living in nearby municipalities. Our evidence shows a significant (positive) effect of such spatial network effects, which are characterized by a quick distance decay, suggesting spatial spillovers at the household and social network level. Additionally, we show that local conditions and immigrant pool characteristics differ, with respect to self-employment choices, when examining separately urban and rural contexts.

description: This article documents the need for reform of milk pricing in the Northeast. The New York price gouging law can be recast as a fair share law. This new milk policy "kills two birds with one stone." It corrects regional inequities in raw milk pricing by reforming the pricing of milk at retail by limiting and redistributing excessive retail margins to farmers and consumers. The fair share policy relieves allocative price inefficiency, improves the performance of the federal milk market order pool, and improves the general performance of the Northeast dairy farming and fluid milk industries.

description: Repeat-until-success strategy is a standard method to obtain success with a probability which grows exponentially in the number of iterations. However, since quantum systems are disturbed after a quantum measurement, it is not straightforward how to perform repeat-until-success strategies in certain quantum algorithms. In this paper, we propose a new structure for probabilistic higher-order transformation named success-or-draw, which allows a repeat-until-success implementation. For that we provide a universal construction of success-or-draw structure which works for any probabilistic higher-order transformation on unitary operations. We then present a semidefinite programming approach to obtain optimal success-or-draw protocols and analyze in detail the problem of inverting a general unitary operation.

description: In this paper, we evaluate the R&D enhancing effects of two large public grant schemes aiming at encouraging the performance of firms organized in clusters. These are Germany's well known BioRegio and BioProfile contests for which we compare the research performance of winning regions in contrast with non-winning and non-participating comparison regions. We apply Difference-in-Difference estimation techniques in a generalized linear model framework, which allows to control for different initial regional conditions in the biotechnology related R&D activity. Our econometric findings support the view that winners generally outperform non-winning participants during the treatment period, thus indicating that exclusive funding as well as the stimulating effect of being a “winner" seems to work in the short-term. In contrast, no indirect impacts stemming from a potential mobilizing effect of the contest approaches have been detected. Also, we find only limited evidence for long-term effects of public R&D grants in the post-treatment period. The results of our analysis remain stable if we additionally augment the model to account for the particular role of spatial dependence in the R&D outcome variables.

description: This paper examines grocery retailers' ability to influence prices charged to consumers and paid to suppliers. We discuss how retailer market power manifests itself in terms of pricing and marketing strategies by setting forth and offering evidence in support of eight "stylized facts" of retailer pricing and brand decisions. We argue that little, if any, of this behavior can be explained by a model of a competitive, price-taking retailer, but that most of the indicated behavior was also inconsistent with traditional models of market power. Finally, we discuss the impacts of aspects of this retailer behavior on the upstream farm sector.

description: Perron's test, Johansen cointegration analysis, and a vector error-correction (VEC) model are used to identify structural change, as well as to examine price dynamics in the U.S. and Canadian hard red spring (HRS) and durum wheat markets. It is found that, due to the U.S. Export Enhancement Program (EEP), price instability experienced in June 1986 has resulted in structural changes for Canadian HRS and durum prices. We also find that Canadian prices have significant effects on the determination of the U.S. prices in the North American wheat market.
Stealth Communication: Zero-Power Classical Communication, Zero-Quantum Quantum Communication and Environmental-Noise Communication

description: An alternative physical way of communication, communication by the inherent background noise, is proposed which does not need net energy transfer in the information channel. The communicator devices do dissipate energy; however, they do not emit net energy into the channel, instead of that, they modulate the parameters of inherent spontaneous fluctuations in the channel. The method can use two different mechanisms, thermal noise (Johnson-Nyquist noise) for classical communication, and vacuum fluctuations/zero point energy (quantum uncertainty noise) for quantum communication. The strongest advantage of the method that this is apparently the most hidden (stealth) way of communication, because it is using the inherent background noise for communication, therefore it is extremely difficult or impossible to discover its presence. With proper wave-based arrangements and specific conditions, the sender and the receiver can easily detect eavesdropper activities, so that the eavesdropper is detected as soon as she extracts a single bit of information, thus the security of the method is comparable to the security of quantum communication/quantum key distribution schemes. Finally, concerning practical applications, environmental noise, out of the fundamental/inherent fluctuations, can also be used for this kind of communication provided that is sufficiently stationary.

description: The geographical distribution and persistence of regional/local unemployment rates in heterogeneous economies (such as Germany) have been, in recent years, the subject of various theoretical and empirical studies. Several researchers have shown an interest in analysing the dynamic adjustment processes of unemployment and the average degree of dependence of the current unemployment rates or gross domestic product from the ones observed in the past. In this paper, we present a new econometric approach to the study of regional unemployment persistence, in order to account for spatial heterogeneity and/or spatial autocorrelation in both the levels and the dynamics of unemployment. First, we propose an econometric procedure suggesting the use of spatial filtering techniques as a substitute for fixed effects in a panel estimation framework. The spatial filter computed here is a proxy for spatially distributed region-specific information (e.g., the endowment of natural resources, or the size of the ‘home market’) that is usually incorporated in the fixed effects parameters. The advantages of our proposed procedure are that the spatial filter, by incorporating region-specific information that generates spatial autocorrelation, frees up degrees of freedom, simultaneously corrects for time-stable spatial autocorrelation in the residuals, and provides insights about the spatial patterns in regional adjustment processes.

We present several experiments in order to investigate the spatial pattern of the heterogeneous autoregressive parameters estimated for unemployment data for German NUTS-3 regions. We find widely heterogeneous but generally high persistence in regional unemployment rates.

description: Agriculture surveys and literature establish that sorghum was of the most important food crops in Mozambique. A large number of farmers have been shifting production gradually from sorghum to maize production despite its susceptibility to drought. The general objective of this study is to identify the factors responsible for decline of sorghum production in Mozambique. Comparative analysis between sorghum and maize are done. Enterprise budgets and break even analysis for both sorghum and maize are presented and discussed. Supply functions for sorghum and maize from 1950 to 1985 are estimated. It is concluded that the major factors responsible for sorghum production decline are the lack of security in the country side, drought during the last ten years, lack of seed, poor varieties, and inappropriate marketing policies. The estimated supply equation for maize suggests raising of official maize prices to increase the output of maize.
Cumulative geometric frustration in physical assemblies

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Geometric frustration arises whenever the constituents of a physical assembly locally favor an arrangement that cannot be realized globally. Recently, such frustrated assemblies were shown to exhibit filamentation, size limitation, large morphological variations and other exotic response properties. While these unique characteristics can be shown to be a direct outcome of the geometric frustration, some geometrically frustrated systems do not exhibit any of the above phenomena. In this work we exploit the intrinsic approach to provide a framework for directly addressing the frustration in physical assemblies. The framework highlights the role of the compatibility conditions associated with the intrinsic fields describing the physical assembly. We show that the structure of the compatibility conditions determines the behavior of small assemblies, and in particular predicts their super-extensive energy growth exponent. We illustrate the use of this framework to several well known frustrated assemblies.

description: The paper deals with application of GPS radio occultation (RO) measurements aboard CHAMP for the retrieval of tropospheric water vapor profiles. The GPS RO technique provides a powerful tool for atmospheric sounding which requires no calibration, is not affected by clouds, aerosols or precipitation, and provides an almost uniform global coverage. We briefly overview data processing and retrieval of vertical refractivity, temperature and water vapor profiles from GPS RO observations. CHAMP RO data are available since 2001 with up to 200 high resolution atmospheric profiles per day. Global validation of CHAMP water vapor profiles with radiosonde data reveals a bias of about 0.2 g/kg and a standard deviation of less than 1 g/kg specific humidity in the lower troposphere. We demonstrate potentials of CHAMP RO retrievals for monitoring the mean tropospheric water vapor distribution on a global scale.

description: This paper tries to study rice price movements and relationships that might exist between rice prices of different selected countries; furthermore, some demand relations for rice will be constructed. Factors influencing consumption such as changes in population and incomes will also be discussed. The period under study will be from after the Second World War to 1960. Rice price fluctuations can be observed from year to year both in local markets and in international trade. This is due to differing demand and supply conditions. On the one hand, production has greatly fluctuated, because of acreage and yield variations; on the other, rice consumption has changed patterns in many countries.

description: We present the results of our search for optical counterparts to high-mass X-ray transient sources discovered by various X-ray missions. We obtained CCD images of the X-ray fields through BVR and Halpha filters in order to identify early-type stars in the R-Halpha versus B-V colour-colour diagram. We also obtained medium-resolution spectroscopy of the candidates in order to confirm the presence of Hαemission and perform spectral classification. We report on the discovery of the optical counterparts to two X-ray sources: XTE J1858+034 and IGR J01363+6610, and the follow-up observations of another two, newly identified by our group: SAX J2103.5+4545 and GRO J2058+42. For another source, IGR J00370+6122, we present the first detailed optical spectral analysis. The optical photometry and spectroscopy reveal B-type companions in all five sources; GRO J2058+42, SAX J2103.5+4545 and IGR J01363+6610 are positively identified with Be/X-ray binaries, IGR J00370+6122 with a supergiant X-ray binary, while the nature of XTE J1858+034 is uncertain. We also study the relationship between the optical and X-ray emission during quiescent states.

We consider in particular the Rindler for both massless and massive fields, the static de Sitter and Schwarzschild black hole backgrounds for massive fields. We find that in all three cases, when any of the temperatures is different from the canonical one (Unruh, Hawking and Gibbons--Hawking, correspondingly) the correlation functions have extra singularities at the horizon.

Publisher: name: Unknown
Year: 1991
Subjects: Livestock Production/Industries

description: As the number of animals per farm have increased, the amount of manure on the individual farms has risen accordingly. With this greater volume of manure, there is a greater potential for pollution and a greater need to manage the manure in an appropriate manner. This increased amount of manure with an increased rural population has resulted in an escalating number of conflicts between livestock producers and their neighbors. In attempts to resolve these conflicts, the need for generally accepted waste management practices has been revealed. The intent of this study is to describe, assess, and analyze livestock manure management issues with specific analytic attention addressed to the swine enterprise. Swine was selected because of its economic importance to the Michigan economy and recent litigation challenging the manure management practice of individual swine producers.

description: Paper tapes from a computerized concentrate feeding system, "The Executive 8085," were collected from six Michigan farms for three months. The tapes contained each cow's identification number, the amount of feed programmed, and the amount of feed consumed by each cow. Cows had actuators on their neck chains which allowed the microprocessor to identify individual cows, limit the feed provided for each animal, and record the feed consumed. Every twelve hours a new tape was generated for the herd. Three hypotheses were investigated in this paper. Hypothesis one: reduced feed consumption would be correlated with the onset of estrus, as indicated by the feeder. Hypothesis two: reduced feed consumption would be correlated with animal diseases, as indicated by the feeder. Hypothesis three: investment cost of the unit will be recouped in just three years through savings in reduced feed costs. Hypotheses one and two were rejected, and hypothesis three was accepted. These case studies illustrate the challenges managers and researchers may have in utilizing computerized individual cow feeders in field environments.
Campaigns, the media and insurgent success : the Reform party and the 1993 Canadian election
Creators: name: Jenkins, Richard W.
Publisher: name: University of British Columbia
Year: 2009

description: It is well recognized that the 1993 election campaign catapulted the Reform party into the national political scene, but our understanding of how this was possible is quite limited. Drawing on the work in cognitive psychology on attitude change, the work on the news media coverage of elections, and the political science work on election campaigns, this thesis locates the impetus for Reform's success in the dynamic flow of information about the party that was available in television news broadcasts and voters' likelihood of being persuaded by that information. This link is developed by an analysis that makes use of a content analysis of the 1993 campaign, the 1993 Canadian Election Study, and a merged analysis of the election and news data. The Reform party began the campaign as a minor component of the news coverage of the election, but the news media coverage changed dramatically. Reform was provided with more news access than its support indicated it deserved and that coverage focused on what became a major theme of the election; the welfare state and the role of government. Coverage of Reform underwent a further change as it both decreased and focused on cultural issues during the last two weeks of the campaign. Using a two-mediator model of attitude change, the analysis shows that people who were predisposed to agree with Reform's anti-welfare state message and who were likely to be aware of the news information, changed both their perceptions of the party and increased their support for the party. Further support for the impact of the media is derived from the analysis of voter response to the second change in news coverage. The analysis suggests that campaigns do matter, but that the size of the impact is dependent upon the underlying uncertainty associated with the parties and candidates, and on the degree to which the information flow of the campaign changes. The information flow contributes to both learning and priming among people who receive and accept new information. While voters respond reasonably to new information, the outcome will depend on what information voters are given and what information actually reaches the habitually unaware segments of the population.

description: After a lengthy period of negotiations, Greece became the tenth member of the European Economic Community. The most important problems to overcome in reaching the Treaty of Accession were those associated with the integration of Greek agriculture into the Common Agricultural Policy (CAP). The importance of the farm sector for the Greek economy as a whole, the structural problems it faces, and the political weight of the Greek farmers led to an agreement on the necessity of a five year transitional period during which Greece will have to adjust progressively to fully adopting the CAP. The major concern of this study is to examine the impact of the changes which are required for the reorientation of the Greek agricultural policy on Greece's agriculture and particularly on its feedgrain-livestock subsector. The specific objectives of the paper are: 1) to provide an overview of the organizational structure of the Greek feedgrain-livestock subsector; 2) to examine the agricultural policy in Greece and the adjustments associated with the accession to the EEC; 3) to analyze production, consumption, and trade of livestock and feedstuffs trends during the last 15 years and to project them in 1985 and 1990; and 4) to draw conclusions regarding the changes that EEC membership is going to impose on the development of the Greek feedgrain-livestock subsector.

description: The phonon dispersion relations of crystal lattices can often be well-described with the harmonic approximation. However, when the potential energy landscape exhibits more anharmonicity, for instance, in case of a weakly bonded crystal or when the temperature is raised, the approximation fails to capture all crystal lattice dynamics properly. Phonon-phonon scattering mechanisms become important and limit the phonon lifetimes. We take a novel approach and simulate the phonon dispersion of a complex dynamic solid at elevated temperatures with Machine-Learning Force Fields of near-first-principles accuracy. Through large-scale molecular dynamics simulations the projected velocity autocorrelation function (PVACF) is obtained. We apply this approach to the inorganic perovskite CsPbBr$_{3}$. Imaginary modes in the harmonic picture of this perovskite are absent in the PVACF, indicating a dynamic stabilization of the crystal. The anharmonic nature of the potential makes a decoupling of the system into a weakly interacting phonon gas impossible. The phonon spectra of CsPbBr$_{3}$ show the characteristics of a phonon liquid. Rattling motions of the Cs$^{+}$ cations are studied by self-correlation functions and are shown to be nearly dispersionless motions of the cations with a frequency of $\sim$0.8THz within the lead-bromide framework.

description: In recent years the condition of our physical environment has become an area of increasing public concern. This concern has manifested itself in the form of legislated rules, formulated and administered by public agencies at the local, state, and federal levels, designed to control the use and degradation of the environment in a manner consistent with societal goals and objectives. Of the forms of environmental degradation pollution of the air and waters has received particular attention. Agriculture has a number of sources or potential sources of pollution. These include: (1) human wastes from the farm (human) population; (2) crop residues; (3) food processing wastes; (4) dead animals; (5) agricultural chemical residues; and (6) animal wastes. Controlling or abating pollution often requires an investment in equipment or other facilities. The financing of investments for abatement of livestock wastes on dairy farms is the topic of this study.

description: Background: Understanding the characteristics of drug users in the night-time economy (NTE), and whether particular drugs are associated with risky practices and experience of harm, is necessary to inform targeted policy responses in this context. Objectives: To investigate the correlates of drugs used in the Australian NTE relating to demographics, alcohol use, and experience of harm. Methods: Patrons were interviewed in the NTE of five Australian cities in 2012–2013 (n = 7,028; 61.9% male, median age 22 years). A custom designed survey gathered demographic data, alcohol, and substance use on the current night, and experience of harm in/around licensed venues in the past 3 months. Multivariate logistic regression analyses examined the correlates of drug use. Results: Ecstasy was most commonly reported (4.0%), followed by cannabis (2.9%), methamphetamine (2.6%), and cocaine (1.6%). Ecstasy users were more likely to be younger and report energy drink consumption. Cannabis users were more likely to be male, and to have been involved in intoxication-related accidents/injuries and sexual aggression in/around licensed venues in the past 3 months. Methamphetamine users were more likely to have been interviewed later, and to have engaged in pre-drinking. Cocaine users were more likely to be male, aged 21 years or more, have a blood alcohol concentration of greater than 0.10%, and to have been involved in intoxication-related accidents/injuries in the past three months. Conclusions/Importance: We identified significant differences between types of drug users and the harms they experience, underscoring the need to develop innovative harm reduction policies in the NTE rather than blanket population-based approaches.

description: The fresh meat industry is changing the way it markets its products. The decline in red meat consumption that has resulted from greater consumer concerns about the "healthfulness" of red meat, coupled with changes in consumer lifestyles emphasizing a need for convenience is contributing to the diminishment of "commodity selling" in favor of a true "marketing" approach (Pierson and Allen, 1986). In a traditional industry such as meats, the shift from a commodity-selling perspective (i.e., selling of homogeneous goods) to a marketing (i.e., selling of homogeneous goods) to a marketing (i.e., marketing of differentiated goods) perspective is a slow transition. The fresh beef industry is moving toward the adoption of this contemporary food marketing strategy by shifting away from the traditional selling of beef as a commodity in favor of marketing differentiated beef products targeted to the wants and needs of specific consumer segments (Pierson and Allen, 1986). This research investigates recent developments in the fresh beef industry and assesses the implications of these developments for consumers, retailers, processors and producers. Beef marketing programs are reviewed in the following areas: 1) The introduction of close-trim programs by the meat industry: 2) The introduction of " light" (reduced fat content) beef: 3) The introduction of "natural" (hormone-free) beef; 4) The introduction of branded and branded case-ready beef by leading processors and retailers

description: We report the detection of a 3.6sigma 350micron-selected source in the Bootes Deep Field. The source, the first Short-wavelength Submillimeter-selected Galaxy (SSG 1), was discovered as part of a blank field extragalactic survey using the 350micron-optimised Submillimeter High Angular Resolution Camera (SHARC II) at the Caltech Submillimeter Observatory. With multiwavelength photometry from NOAO-NDWFS (R and I band), FLAMEX (J and K_s), Spitzer (IRAC and MIPS) and the Westerbork 1.4GHz Deep Survey (radio upper limit), we are able to constrain the photometric redshift using different methods, all of which suggest a redshift of close to 1. In the absence of long-wavelength submillimeter data we use SED templates to infer that this source is an ultraluminous infrared galaxy (ULIRG) with a dust temperature of 30+/-5 K, occupying a region of luminosity-temperature space shared by modarate redshift ISO-selected ULIRGs (rather than high redshift SCUBA-selected SMGs). SHARC II can thus select SMGs with moderately "warm'' dust that might be missed in submillimeter surveys at longer wavelengths.
