    Identification of optimal poultry litter biorefinery location in Alabama through minimization of feedstock transportation cost

    ENVIRONMENTAL PROGRESS & SUSTAINABLE ENERGY, Issue 4 2008
    Burak Aksoy
    Abstract The estimated amount of poultry litter produced annually in Alabama is more than 1,250,000 tons. This large amount results in significant litter management challenges. Currently, poultry producers are facing many regulatory issues and challenges with respect to environmental impacts of litter management. Commercialization and implementation of environmentally benign biorefinery technologies have the potential to generate electric power (including on-site power) and heat as well as transportation fuels, hydrogen, valuable chemicals, and fertilizer from poultry litter economically while addressing environmental problems caused by traditional disposal practices. In this study, poultry litter generated annually in northern and southern Alabama was documented on the basis of published literature, and transportation cost of poultry litter is minimized for both north and south Alabama by the selection of the best large-scale biorefining facility location and optimal feedstock allocation using mathematical optimization techniques. The available portion of the existing poultry litter feedstock for a large scale biorefinery is found to be an important factor in determining transportation cost. Transportation cost increases several fold as the local feedstock availability for biorefining reduces from 100 to 50%. Optimum facility locations for both north and south Alabama were found within a 10 mile radius for three different poultry litter feedstock availabilities. © 2008 American Institute of Chemical Engineers Environ Prog, 2008 [source]


    Commercialization of Nanostructured Metals Produced by Severe Plastic Deformation Processing

    ADVANCED ENGINEERING MATERIALS, Issue 5 2003
    T.C. Lowe
    Abstract The promise of nanotechnology is increasingly being realized as governments, universities, public and private research laboratories, and the various industrial sectors devote resources to this emerging area. Estimates for the economic impact of nanotechnology on existing global markets exceed 700 billion by the year 2008. Nanomaterials are projected to be one of the earliest components of nanotechnology to appear in commercial applications. Amongst the emerging new nanomaterials, bulk nanostructured metals produced by severe plastic deformation (SPD) have shown promise in a wide range of application areas. In this paper, we overview developments in severe plastic deformation technology, emphasizing progress since the international workshop "Investigations and Applications of Severe Plastic Deformation" held 2,8 August 1999 in Moscow, Russia. Then, we overview some of principal areas of application for SPD metals and alloys. [source]


    Market facilities and agricultural marketing: evidence from Tamil Nadu, India

    AGRICULTURAL ECONOMICS, Issue 3 2008

    Market facility; Agricultural markets; Commercialization; Transaction costs Abstract This article analyzes the effect of facilities and infrastructure available at the marketplace on a farmer's decision to sell at the market. The econometric estimation shows that the likelihood of sales at the market increases significantly with an improvement in market facilities and a decrease in travel time from the village to the market. The results suggest that wealth reduces a farmer's cost of accessing market facilities more than it increases her/his opportunity cost of leisure. The policy simulation indicates that the marginal benefits from an improvement in market facility will favor the poorer farmers in the context of India. [source]

    Supply-Side Innovation and Technology Commercialization

    JOURNAL OF MANAGEMENT STUDIES, Issue 4 2009
    Gideon D. Markman
    abstract The majority of research and practice tends to conceptualize innovation as a vertically coupled, intra-organizational process. We expand this perspective by conceptualizing innovation as a vertically decoupled, inter-organizational process and by studying the role of research universities as suppliers of discoveries to this market for innovation. We combined logic from agency and real options theories to explain why the outcomes of technology commercialization are a function of licensing strategies, the autonomy of technology licensing offices (TLOs), and the incentives bestowed on scientists, research departments, and TLO officers. We rely on data from licensing surveys, interviews with 128 TLO directors, and , for convergent validity , from web-based searches of the TLOs of American universities and the US Patent and Trademark Office. Results suggest that commercialization outcomes (in this case, revenue and start-up creation) are enhanced when TLOs employ diverse licensing strategies, TLOs enjoy greater autonomy, universities share revenues with scientists' departments, and universities compensate TLOs officers well. Results also show that late entrants , typically underperforming universities , inflate royalty shares to scientists as a means to rectify their commercialization record. We conclude with a discussion of this study's contribution to the literature on innovation and technology commercialization. [source]


    Utilisation of corn (Zea mays) bran and corn fiber in the production of food components,

    JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE, Issue 6 2010
    Devin J Rose
    Abstract The milling of corn for the production of food constituents results in a number of low-value co-products. Two of the major co-products produced by this operation are corn bran and corn fiber, which currently have low commercial value. This review focuses on current and prospective research surrounding the utilization of corn fiber and corn bran in the production of potentially higher-value food components. Corn bran and corn fiber contain potentially useful components that may be harvested through physical, chemical or enzymatic means for the production of food ingredients or additives, including corn fiber oil, corn fiber gum, cellulosic fiber gels, xylo-oligosaccharides and ferulic acid. Components of corn bran and corn fiber may also be converted to food chemicals such as vanillin and xylitol. Commercialization of processes for the isolation or production of food products from corn bran or corn fiber has been met with numerous technical challenges, therefore further research that improves the production of these components from corn bran or corn fiber is needed.

    Commentary: Emerging Technologies Oversight: Research, Regulation, and Commercialization

    THE JOURNAL OF LAW, MEDICINE & ETHICS, Issue 4 2009
    Robbin Johnson
    This paper reviews the paper by Kuzma, Najmaie, and Larson that looks at what can be learned from the experience with genetically engineered organisms for oversight of emerging technologies more generally. That paper identifies key attributes of a good oversight system: promoting innovation, ensuring safety, identifying benefits, assessing costs, and doing so all while building public confidence. In commenting on that analysis, this paper suggests that looking at "oversight" in three phases , research and development, regulatory review, and market acceptance , can help to determine when certain of these attributes should take precedence over others and how to structure remedies when an error occurs. The result is an approach that is precautionary with respect to research and development, prudent and open to public input in the regulatory review stage, and purposefully persuasive once market acceptability is at stake, with remedies that are risk-containing in the first phase, risk-managing in the second, and risk-assuaging in the third. Combining the key attributes with the idea of three phases can help attune oversight to society's needs. [source]

    The Role of Champions in the External Commercialization of Knowledge,

    THE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 4 2009
    Ulrich Lichtenthaler
    Besides applying knowledge in their own products or services, firms may externally commercialize their knowledge assets (e.g., by means of outlicensing). The literature on champions, however, has focused on internal innovation. This gap in prior research is particularly remarkable as the potential for promoting external knowledge exploitation is high. Some pioneering firms realize great benefits, whereas most others experience major managerial difficulties. This paper tests five hypotheses regarding the emergence and impact of champions of external knowledge exploitation with data from 152 firms across industries. The results of the questionnaire-based study demonstrate the relevance of champions of external knowledge exploitation. Championing constitutes an essential success factor and has strongly contributed to the recent increase in external knowledge commercialization. These findings help to explain the discrepancies between the few successful and the majority of unsuccessful firms. Beyond existing insights, the emergence of champions is affected by external determinants in addition to internal determinants. There is an inverted U-shaped relationship between championing and the internal determinants, that is, organizational climate and active strategy. Moreover, there is a negative relationship between championing and market imperfection and an inverted U-shaped relationship between championing and competitive intensity, which both constitute external determinants of championing. In contrast to the traditional understanding, champions tend to emerge in supportive environments, in which internal and external barriers are relatively low. This surprising finding calls for rethinking the role and motivation of champions. [source]

    Does the Commercialization of Voluntary Organizations ,Crowd out' Voluntary Work?

    ANNALS OF PUBLIC AND COOPERATIVE ECONOMICS, Issue 3 2002
    Bernard Enjolras
    This article examines the relationship among voluntary labour supply and commercial income for Norwegian sport voluntary organizations. Empirical results using cross,sectional data on voluntary sport organizations in Norway and on their members show a decrease in voluntary work from an increase in commercial income. Voluntary work and commercial income appear as substitutable resources. Nevertheless, the results have to be differentiated according to the professional situation of the volunteers. A crowding out effect between voluntary work and commercial resources is at play for non,professionally active individuals whereas professionally active individuals seem to be indifferent to the level of commercial resources in deciding whether to volunteer or not.

    Commercializing air traffic control: Have the reforms worked?

    CANADIAN PUBLIC ADMINISTRATION/ADMINISTRATION PUBLIQUE DU CANADA, Issue 1 2008
    Glen McDougall
    Many countries have restructured their ANSPs by granting managerial and financial autonomy and creating new mechanisms for regulation and accountability to major consumers of air navigation services. These reforms have exemplified principles often associated with the New Public Management. The United States is the major exception to this international trend. Commercialization has allowed significant improvements in service quality without substantial increases in cost of service or erosion of safety standards. Other public interest considerations have also been protected. These performance benefits can be attributed to key decisions on the governance of new air navigation service organizations. Sommaire: Les fournisseurs de services de navigation aérienne jouent un rôle crucial dans le fonctionnement d'une économie moderne. De nombreux pays ont restructuré leurs fournisseurs de services en leur accordant une autonomie financière et de gestion, et en créant de nouveaux mécanismes de réglementation et d'imputabilité envers les principaux consommateurs de services de navigation aérienne. Ces réformes ont illustré les principes souvent associés à la Nouvelle gestion publique. Les États-Unis sont la principale exception à cette tendance internationale. La commercialisation a permis d'apporter d'importantes améliorations à la qualité des services sans entraîner pour autant d'augmentations substantielles des coûts de services, ou une érosion des normes de sécurité. D'autres considérations d'intérêt public ont également été protégées. Ces avantages en termes de performance peuvent être attribués à des décisions clés en matière de gouvernance des nouveaux organismes de services de navigation aérienne. [source]


    Technology-Based New Product Development Partnerships,

    DECISION SCIENCES, Issue 2 2006
    John E. Ettlie
    ABSTRACT Hypotheses were developed to capture the dynamic capabilities that result from interfirm partnerships during the joint new product development (NPD) process,the ability to build, integrate, and reconfigure existing resources to adapt to rapidly changing environments. These capabilities, in turn, were proposed to have a positive impact on NPD performance outcomes: (a) proportion of new product success and (b) superior new product commercialization. In contexts where the locus of innovation is rapidly changing, the impact of interfirm NPD dynamic capabilities was hypothesized to be diminished in high-technology contexts, especially for buyers (original equipment manufacturers) and to a lesser extent for suppliers. Still, technology-based interfirm NPD partnerships were predicted to ultimately outperform low-technology ones in both NPD performance outcomes. Finally, information technology (IT) support for NPD was hypothesized to influence the interfirm NPD partnership's dynamic capabilities. Using survey data from 72 auto company managers and their suppliers, the proposed model in which IT support for NPD influences the success of interfirm NPD partnerships through the mediating role of interfirm NPD partnership dynamic capabilities in high- and low-technology contexts was generally supported. The results shed light on the nature of technology-based interfirm NPD partnerships and have implications for their success. Theoretical and managerial implications are discussed. [source]


    Selling archaeology and anthropology: early medieval artefacts at the Expositions universelles and the Wiener Weltausstellung, 1867,1900

    EARLY MEDIEVAL EUROPE, Issue 1 2008
    Bonnie Effros
    The archaeological and anthropological exhibits included in the four Expositions universelles held in Paris between 1867 and 1900 and the Wiener Weltausstellung in the Austro-Hungarian capital in 1873, contributed to the commercialization of antiquarianism and granted international attention to the amateur practitioners of these emerging disciplines. Displays of archaeological artefacts and human remains from the migration period and the early Middle Ages, juxtaposed with more exotic ,primitive' art, permitted organizers to broaden the aesthetic sensibilities of fairgoers and promote the acquisition of native antiquities. Exhibiting private collections of early medieval objects likewise justified nineteenth-century concepts of French and ,pan-Germanic' identity by linking them to iconic artefacts and romanticizing the barbarity of this distant epoch.

    High-Performance Alkaline Polymer Electrolyte for Fuel Cell Applications

    ADVANCED FUNCTIONAL MATERIALS, Issue 2 2010
    Jing Pan
    Abstract Although the proton exchange membrane fuel cell (PEMFC) has made great progress in recent decades, its commercialization has been hindered by a number of factors, among which is the total dependence on Pt-based catalysts. Alkaline polymer electrolyte fuel cells (APEFCs) have been increasingly recognized as a solution to overcome the dependence on noble metal catalysts. In principle, APEFCs combine the advantages of and alkaline fuel cell (AFC) and a PEMFC: there is no need for noble metal catalysts and they are free of carbonate precipitates that would break the waterproofing in the AFC cathode. However, the performance of most alkaline polyelectrolytes can still not fulfill the requirement of fuel cell operations. In the present work, detailed information about the synthesis and physicochemical properties of the quaternary ammonia polysulfone (QAPS), a high-performance alkaline polymer electrolyte that has been successfully applied in the authors' previous work to demonstrate an APEFC completely free from noble metal catalysts (S. Lu, J. Pan, A. Huang, L. Zhuang, J. Lu, Proc. Natl. Acad. Sci. USA2008, 105, 20611), is reported. Monitored by NMR analysis, the synthetic process of QAPS is seen to be simple and efficient. The chemical and thermal stability, as well as the mechanical strength of the synthetic QAPS membrane, are outstanding in comparison to commercial anion-exchange membranes. The ionic conductivity of QAPS at room temperature is measured to be on the order of 10,2,S cm,1. Such good mechanical and conducting performances can be attributed to the superior microstructure of the polyelectrolyte, which features interconnected ionic channels in tens of nanometers diameter, as revealed by HRTEM observations. The electrochemical behavior at the Pt/QAPS interface reveals the strong alkaline nature of this polyelectrolyte, and the preliminary fuel cell test verifies the feasibility of QAPS for fuel cell applications.

    Designing a Stable Cathode with Multiple Layers to Improve the Operational Lifetime of Polymer Light-Emitting Diodes

    ADVANCED FUNCTIONAL MATERIALS, Issue 12 2009
    Tae-Woo Lee
    Abstract The short device lifetime of blue polymer light-emitting diodes (PLEDs) is still a bottleneck for commercialization of self-emissive full-color displays. Since the cathode in the device has a dominant influence on the device lifetime, a systematic design of the cathode structure is necessary. The operational lifetime of blue PLEDs can be greatly improved by introducing a three-layer (BaF2/Ca/Al) cathode compared with conventional two-layer cathodes (BaF2/Al and Ba/Al). Therefore, the roles of the BaF2 and Ca layers in terms of electron injection, luminous efficiency, and device lifetime are here investigated. For efficient electron injection, the BaF2 layer should be deposited to the thickness of at least one monolayer (,3,nm). However, it is found that the device lifetime does not show a strong relation with the electron injection or luminous efficiency. In order to prolong the device lifetime, sufficient reaction between BaF2 and the overlying Ca layer should take place during the deposition where the thickness of each layer is around that of a monolayer.

    Luminescent Colloidal Dispersion of Silicon Quantum Dots from Microwave Plasma Synthesis: Exploring the Photoluminescence Behavior Across the Visible Spectrum

    ADVANCED FUNCTIONAL MATERIALS, Issue 5 2009
    Anoop Gupta
    Abstract Aiming for a more practical route to highly stable visible photoluminescence (PL) from silicon, a novel approach to produce luminescent silicon nanoparticles (Si-NPs) is developed. Single crystalline Si-NPs are synthesized by pyrolysis of silane (SiH4) in a microwave plasma reactor at very high production rates (0.1,10,g,h,1). The emission wavelength of the Si-NPs is controlled by etching them in a mixture of hydrofluoric acid and nitric acid. Emission across the entire visible spectrum is obtained by varying the etching time. It is observed that the air oxidation of the etched Si-NPs profoundly affects their optical properties, and causes their emission to blue-shift and diminish in intensity with time. Modification of the silicon surface by UV-induced hydrosilylation also causes a shift in the spectrum. The nature of the shift (red/blue) is dependent on the emission wavelength of the etched Si-NPs. In addition, the amount of shift depends on the type of organic ligand on the silicon surface and the UV exposure time. The surface modification of Si-NPs with different alkenes results in highly stable PL and allows their dispersion in a variety of organic solvents. This method of producing macroscopic quantities of Si-NPs with very high PL stability opens new avenues to applications of silicon quantum dots in optoelectronic and biological fields, and paves the way towards their commercialization.

    Misconduct in medical research: whose responsibility?

    INTERNAL MEDICINE JOURNAL, Issue 4 2003
    K. J. Breen
    Abstract Examples of many types of misconduct in medical research continue to be reported. The true incidence is unknown because there is strong evidence of under-reporting as well as suggestions of increased detection. Risks to research participants may also be increasing, with contributing factors such as increased pressure on researchers to publish and to produce commercialization of their research. Institutions are perceived to typically respond slowly and inadequately to allegations of research misconduct. More could be done to try to prevent such mis­conduct, such as: (i) educating researchers about research ethics, (ii) assisting and protecting whistleblowers and (iii) instituting processes to adequately and promptly investigate and deal with allegations. In addition, a debate needs to take place as to whether research misconduct allegations should be dealt with at the institutional level or at a national level and whether medical boards should be routinely involved in the more serious breaches of ethical standards by medical practitioners engaged in research.

    Three-Dimensional Microstructural Characterization of Porous Hydroxyapatite Using Confocal Laser Scanning Microscopy

    INTERNATIONAL JOURNAL OF APPLIED CERAMIC TECHNOLOGY, Issue 3 2005
    Fei Ren
    The characterization of porosity is crucial in the development and commercialization of ceramic bone replacement technology, since the pore size and interconnectivity play a central role in both biological function (bone ingrowth and nutrient flow) as well as mechanical properties of bone scaffolds. The ability of confocal laser scanning microscopy (CLSM) to image three-dimensional (3-D) structures with large vertical depths (,2 mm) and fine vertical resolution (,1 ,m) is utilized in this article to characterize the 3-D microstructures of hydroxyapatite (HA) bone scaffold specimens with porosity ranging from roughly 60,70 vol%. Various CLSM techniques are applied to image and interpret the HA pore structure, including Z -series stacking, topographic profiling, and Phi- Z scanning and contour mapping. [source]


    Innovation management measurement: A review

    INTERNATIONAL JOURNAL OF MANAGEMENT REVIEWS, Issue 1 2006
    Richard Adams
    Measurement of the process of innovation is critical for both practitioners and academics, yet the literature is characterized by a diversity of approaches, prescriptions and practices that can be confusing and contradictory. Conceptualized as a process, innovation measurement lends itself to disaggregation into a series of separate studies. The consequence of this is the absence of a holistic framework covering the range of activities required to turn ideas into useful and marketable products. We attempt to address this gap by reviewing the literature pertaining to the measurement of innovation management at the level of the firm. Drawing on a wide body of literature, we first develop a synthesized framework of the innovation management process consisting of seven categories: inputs management, knowledge management, innovation strategy, organizational culture and structure, portfolio management, project management and commercialization. Second, we populate each category of the framework with factors empirically demonstrated to be significant in the innovation process, and illustrative measures to map the territory of innovation management measurement. The review makes two important contributions. First, it takes the difficult step of incorporating a vastly diverse literature into a single framework. Second, it provides a framework against which managers can evaluate their own innovation activity, explore the extent to which their organization is nominally innovative or whether or not innovation is embedded throughout their organization, and identify areas for improvement.

    External commercialization of knowledge: Review and research agenda

    INTERNATIONAL JOURNAL OF MANAGEMENT REVIEWS, Issue 4 2005
    Ulrich Lichtenthaler
    Companies increasingly make use of external knowledge exploitation, i.e. the commercialization of knowledge assets, although they often perceive considerable difficulties in managing external commercialization tasks. These difficulties are partly due to the imperfections in the markets for knowledge, which may be mastered by adequate management, as examples of various well-known companies show. In combination, these facts point to the need for research into external knowledge exploitation. A thorough analysis of past research confirms this need and shows that the existing literature is highly fragmented. By integrating the main findings of the different research streams, a detailed overview of the literature on external knowledge exploitation is established. The key characteristics of externally leveraging knowledge assets are presented, and a research agenda is set up. [source]


    Where will pathogen inactivation have the greatest impact?

    ISBT SCIENCE SERIES: THE INTERNATIONAL JOURNAL OF INTRACELLULAR TRANSPORT, Issue 1 2007
    T. Hervig
    Blood safety has always been a major task in transfusion medicine. A strategy to obtain this aim should include donor education, donor selection, and testing of blood donations. Pathogen inactivation adds another level of safety. In the fractionation industry, pathogen inactivation methods are mandatory. Several countries also use pathogen-inactivated plasma , from pools or single donors. Concerning the cellular blood components, there is still no method available for red cell concentrates, whereas methods for platelet concentrates are available in some countries and others are in the pipeline for commercialization. The efficiency of the ,old' methods to increase blood safety and the costs of the methods seem to be major obstacles for the introduction of the systems. There are also concerns on product quality and loss of volume during the inactivation process. As the importance of pathogen inactivation is largest in countries with blood donors who carry infections it is impossible to protect against, either due to high incidence of the infection or due to shortage of tests, cost will be a major question when pathogen inactivation is considered. Pathogen inactivation of red cell concentrates will also be a necessity. When pathogen inactivation methods are available for all blood components, they will have great impact to protect the patients in countries where a high percentage of the population is infected by agents transmissible through blood transfusion, and in all situations to protect against new pathogens and ,old' pathogens that become more virulent. The total risk of contracting infectious diseases through blood transfusion will probably be important when implementation of new methods for pathogen inactivation is considered. [source]


    Institutional Diversity and Capitalist Transition: The Political Economy of Agrarian Change in Arunachal Pradesh, India

    JOURNAL OF AGRARIAN CHANGE, Issue 4 2009
    BARBARA HARRISS-WHITE
    This paper contributes a preliminary analysis of the process of agrarian capitalist transition in Arunachal Pradesh, one of the least studied regions of India. Primarily based on information collected through a field survey in eleven villages, the paper seeks to explain the nature and implications of institutional unevenness in the development of capitalism. Institutional diversity is not simply mapped across space, it is also manifested in the simultaneous existence of market and non-market institutions across the means of production within the same village or spatial context. In addition, there is a continuous and complex interaction among these institutions which both shapes and is shaped by this capitalist transition. Primitive accumulation emerges as a continuing characteristic of the on-going agrarian and non-agrarian capitalist transition. Institutional adaptation, continuity and hybridity are as integral to the emergence of the market economy as are the processes of creation of new institutions and demise of others. There is no necessary correspondence between the emerging commercialization of the different productive dimensions of the agrarian economy. These uneven processes are deeply influenced by existing and emerging power relations and by the state. Framed by the Bernstein,Byres debate about the contemporary (ir)relevance of the agrarian question, evidence is presented to justify the conclusion that although the processes at work are far from the classical models of the transition to capitalism, all aspects of the agrarian question remain relevant.

    Framing the Carolingian Economy

    This essay argues that the degree of commercialization on Carolingian great estates should not be overstated. Rather, the strategies and ambitions of Carolingian estate managers were primarily determined by a ,domainal' ideology and concerns for good stewardship. Moreover, the structural demands of the Carolingian state may have played a rather more important role in framing economic conditions than is commonly supposed. Here Carolingianists need to learn some of the lessons that have helped to transform the writing of ancient economic history in recent decades. [source]


    Baseline susceptibility of western corn rootworm (Coleoptera: Chrysomelidae) to clothianidin

    JOURNAL OF APPLIED ENTOMOLOGY, Issue 4 2007
    L. C. Magalhaes
    Abstract:, Western corn rootworm, Diabrotica virgifera virgifera LeConte, neonate susceptibility to clothianidin, a contact and systemic neonicotinoid insecticide, was determined from both laboratory and field-collected populations. Neonates were exposed to filter paper treated with increasing clothianidin concentrations and mortality was evaluated after 24 h. Additionally, two populations were exposed to an artificial diet which was surface treated with clothianidin. Although larvae were five- to six-fold more sensitive to treated diet, results with treated filter paper were more reliable in terms of control mortality and required much less manipulation of rootworm larvae. Therefore, initial baseline comparisons were conducted using the filter paper assays. The variation among populations exposed to treated filter paper was generally low, 4.4-fold among laboratory populations tested; however, there was a 14.5-fold difference in susceptibility among all populations tested. In general, clothianidin was very toxic to rootworm neonates, with LC50 values ranging from 1.5 to 21.9 ng/cm2. These results indicate the practicability and sensitivity of the paper filter disc assay to establish baseline susceptibility levels, which is an essential first step in resistance management. A baseline response provides a reference for tracking shifts in susceptibility following commercialization of a control agent so that early changes in susceptibility can be detected. [source]


    Functional enhancement of Sake yeast strains to minimize the production of ethyl carbamate in Sake wine

    JOURNAL OF APPLIED MICROBIOLOGY, Issue 3 2010
    M.S. Dahabieh
    Abstract Aims:, In fermented alcoholic beverages and particularly in Japanese Sake wine, the ubiquitous presence of the probable human carcinogen ethyl carbamate (EC) is a topic of significant concern. This study aims to develop novel methods for the reduction of EC in Sake wine. Methods and Results:, To reduce the high levels of EC in Sake wine, urea-degrading and urea-importing yeast strains were created by integrating linear cassettes containing either the respective DUR1,2 or DUR3 genes, under the control of the constitutively active Saccharomyces cerevisiae PGK1 promoter, into the Sake yeast strains K7 and K9. The self-cloned, urea-degrading Sake strains K7DUR1,2 and K9DUR1,2 produced Sake wine with 87 and 68% less EC, respectively, while the urea-importing Sake yeast strain K7DUR3 reduced EC by 15%. All functionally enhanced yeast strains were shown to be substantially equivalent to their parental strains in terms of fermentation rate, ethanol production, phenotype and transcriptome. Conclusions:, Under the conditions tested, urea-degrading yeast (constitutive DUR1,2 expression) are superior to urea-importing yeast (constitutive DUR3 expression) for EC reduction in Sake wine, and constitutive co-expression of DUR1,2 and DUR3 does not yield synergistic EC reduction. Significance and Impact of the Study:, The self-cloned, substantially equivalent, urea-degrading Sake yeast strains K7DUR1,2 and K9DUR1,2, which contain the integrated DUR1,2 cassette, are capable of highly efficacious EC reduction during Sake brewing trials, are suitable for commercialization and are important tools for modern Sake makers in their efforts to reduce high EC levels in Sake wine.

    Calibration accuracy of a judgmental process that predicts the commercial success of new product ideas

    JOURNAL OF BEHAVIORAL DECISION MAKING, Issue 4 2007
    Thomas Åstebro
    Abstract We examine the accuracy of forecasts of the commercial potential of new product ideas by experts at an Inventor's Assistance Program (IAP). Each idea is evaluated in terms of 37 attributes or cues, which are subjectively rated and intuitively combined by an IAP expert to arrive at a forecast of the idea's commercialization prospects. Data regarding actual commercialization outcomes for 559 new product ideas were collected to examine the accuracy of the IAP forecasts. The intensive evaluation of each idea conducted by the IAP produces forecasts that accurately rank order the ideas in terms of their probability of commercialization. The focus of the evaluation process on case-specific evidence that distinguishes one idea from another, however, and the corresponding neglect of aggregate considerations such as the base rate (BR) and predictability of commercialization for new product ideas in general, yields forecasts that are systematically miscalibrated in terms of their correspondence to the actual probability of commercialization.
