How Different Policies Influence Expected Profit Of the Firm Of Biotechnology Industry Under Uncertain Risks: Genetically Modified Food

Chang, Su-bi 19 July 2007 (has links)
This paper uses the optimal control theory to construct dynamic economic model. The primary purpose of this paper is to discuss how different policies alter the choice problem of the firm and influence the allocation of funds to existing and new research and development activities. I analyze how the fixed-cost regulatory standard and the marginal-cost standard let firm consider externality, in order to protect the consumer of asymmetric information and avoid the problem of adverse selection. The firm maximizes expected profit. At the same time I want to know how the consumer acceptance, mark and audit affect the farmer to purchase the quantity of seed and the allocation of funds . We want to discuss how different price influence the option input path, the option quantity path and the option path . I discuss the different between ultimatum and static model. Finally, I discuss dynamic models in this paper to find out whether there exists a long-term and stable steady state. Saddle-point stability exists under certain restrictions.

Testing USDA Certified Organic and Non-GMO Verified Project Labeled Foods for the Presence of Genetic Modifications

Phelps, Ryan Loren 01 October 2015 (has links)
Genetically Modified Organisms (GMOs) are plants or animals that have been produced using genetic insertion or deletion via technology (also called genetic engineering or GE). Merged DNA from different species creates combinations of plant, animal, bacteria and/or virus genes that cannot occur in nature or in traditional crossbreeding. Our goal was to determine the presence or absence of GMO markers in USDA Organic Certified and in Non-GMO Project food products. We investigated only corn or soy-based products that were purchased from many types of retailers. Our study was limited to products that contained a label for USDA organic certification and/or Non-GMO Verified Project. DNA from each product was extracted, tested for purity, and examined for specific markers denoting the presence of genetic modification. Modified DNA was amplified using PCR techniques and tested against standards on electrophoretic agarose gel. Based on these results, we detected evidence of genetic modification in 75% of soy and 83.3% of corn claiming USDA Organic Certification and 0% of soy and 100% of corn claiming Non-GMO Verified Certification.

At the Intersection of Human Agency and Technology: Genetically Modified Organisms

Libengood, James 05 November 2015 (has links)
Since the Neolithic period and the rise of agriculture along Mesopotamia’s “Fertile Crescent,” greater societies have formed thus requiring laws and governance to ensure their continued preservation. The Babylonian Code of Hammurabi is one such example of how agricultural technologies directly created new social and institutional structures in codifying slavery into law, or how mercantile transactions are to be conducted. Similarly, GMOs are the result of modern agricultural technologies that are altering laws and society as a result of their implementation. This transformation informs the central inquiries of my research question: Why are GMOs necessary, and what influences do they have on the project of human rights? As our age is defined by the products of bioluminescent – or glow-in-the-dark – cats and goats that can excrete spider silk proteins from their mammary glands, these questions become essential. I conclude that the technology does not, at least conceptually, conflict with or undermine human rights. Instrumental reason has firm limitations in biological applications as well as conflict with its inherent anarchical nature. We are now compelled to question the utility of genetic engineering and if it merely places humanity into another precarious “arms race” with weeds and pests, in addition to the pressure of maintaining current dependencies of petrochemicals, fertilizers, and continued observations of ecological homeostasis.

Vad tycker du om genmodifierad mat? : En studie om hur vi tolkar informationsgrafik beroende på ordning och berättargrepp

Szuter, Beata January 2021 (has links)
This bachelor thesis aims to investigate how theories in rhetorics and narratology can be applied to and change the interpretation of information graphics. As a prototype a brochure about genetically modified food was made, a complex topic that can be interpreted in many ways.  To identify the problem and target group an information overview about attitudes toward genetically modified food was made. The methods used for the thesis were prototyping and interviews.  The results are showing that the interpretation of the brochure is dependent on sequential order and composition. This study also presents which elements that clarify the content and influence the credibility, such as narrator grip and illustrations. / Denna studie undersöker hur teorier inom retorik och narratologi kan appliceras på och styra tolkningen av informationsgrafik. Som utprovningsmaterial skapades en broschyr om genmodifierad mat, ett komplext ämne som kan tolkas på många sätt.  För att identifiera problem och målgrupp utfördes en informationsöversikt kring attityder till genmodifierad mat. De metoder som sedan användes är prototyping och intervjuer.  Resultatet visar att broschyrens budskap tolkas olika beroende på sekventiell ordning och komposition. Arbetet redogör även för vilka element som förtydligar innehållet och har en inverkan på trovärdighet, såsom berättargrepp och illustrationer.

Risker med GMO i jordbruket

Sundin, Charlotta January 2009 (has links)
The world is growing more and more genetically modified (or engineered) crops (GM crops). In Argentina farmers grow almost only GM soy, and no conventional soy. It is a controversial subject, since genetic engineering has many advocates and critics. The positive sides of GM crops are that it can create higher yields and incomes for the farmers. Those are the main objects of growing GM crops. Critics, on the other hand, say that GM crops have bad effects on the environment, and the risks could be too high. For example GM crops can spread to neighboring farms, where organic crops are growing. Many scientists claim that nobody really have enough knowledge of the effects of growing GM crops, and therefore thorough risk assessments are needed to examine the effects and possible risks of growing GM crops before starting to grow them. Politicians, too often, make decisions on false scientific grounds, when they claim that genetic engineering is a safe and precise method. The large corporations developing GMOs are heavily influencing political decision making. Scientists have studied the genetic engineering process and the results show that the method is not precise. It is difficult to know exactly what gene is transferred, and where it ends up. It is also important to discuss the precautionary principle in the decision making process.

Environmentálně-ekonomická hlediska pěstování vybraných geneticky modifikovaných plodin v Evropské unii

Ševčík, Michal January 2017 (has links)
ŠEVČÍK, M. Environmental-economic aspects of cultivation of selected genetically modified plants in European Union. Diploma thesis. Mendel University in Brno. Faculty of Regional Development and International Studies, 2017. This diploma thesis deals with the topic of cultivation of selected genetically modified crops in the EU. Literature part describes population development and food production in Europe after the Industrial Revolution, while the other parts are focused on the mechanism of genetic modification of crops, the potential impacts of their cultivation, as well as the perception of this issue in the public and interest groups followed by description of the past and current state of GM crop cultivation in the EU, with particular emphasis on the legislative and institutional framework of the issue. The literature part is concluded by comparison of the environmental and economic impacts of growing MON810 maize on the territory of the Czech Republic, Poland and Slovakia, and a subchapter on the potential benefits of growing Roundup Ready Soy in the EU. The practical part of the thesis presents the results of a one-year soybean experiment with the aim of finding the optimum types and dose of fertilizers for the highest yield and nutritional value of the seed. On the basis of these results, the author of the thesis then estimates the potential of introducing genetically modified soybean - Roundup Ready variety, in EU.

Geneticky modifikované plodiny a možnosti jejich využití - případová studie v České republice

Pillař, Miroslav January 2017 (has links)
This thesis deals with the topic of genetically modified crops and possibilities of their use in the Czech Republic. The attitude of randomly selected group of Czech citizens toward this technology was evaluated by using the method of semi-standardized interviews and questionnaires. The aim of this work was to document actual situation related to GMO and other usage of modified crops in the Czech Republic. From the results it can be seen that the interest of agricultural subjects regarding mentioned technology is decreasing rapidly. The awareness of respondents was mostly of negative character due to confusion about its effects on human health and the environment. On the contrary the scientific community sees the main problem in environmental and biodiversity threats. Due to the lack of long-term scientific researches it is currently impossible to confirm or disprove advantages or disadvantages brought by this technology. Thus further conclusive scientific studies are needed.

Additive Manufacturing for Robust and Affordable Medical Devices

Wolozny Gomez Robelo, Daniel Andre 18 October 2016 (has links)
Additive manufacturing in the form of 3D printing is a revolutionary technology that has developed within the last two decades. Its ability to print an object with accurate features down to the micro scale have made its use in medical devices and research feasible. A range of life-saving technologies can now go from the laboratory and into field with the application of 3D-printing. This technology can be applied to medical diagnosis of patients in at-risk populations. Living biosensors are limited by being Genetically Modified Organisms (GMOs) from being employed for medical diagnosis. However, by containing them within a 3D-printed enclosure, these technologies can serve as a vehicle to translate life-saving diagnosis technologies from the laboratory and into the field where the lower cost would allow more people to benefit from inexpensive diagnosis. Also, the GMO biosensors would be contained with a press-fit, ensuring that the living biosensors are unable to escape into the environment without user input. In addition, 3D-printing can also be applied to reduce the cost of lab-based technologies. Cell patterning technology is a target of interest for applying more cost-effective technologies, as elucidation of the variables defining cell patterning and motility may help explain the mechanics of cancer and other diseases. Through the use of a 3D-printed stamp, bacterial cells can be patterning without the use of a clean room, thus lowering the entry-barrier for researchers to explore cell patterning. With the commercialization of 3D-printing an opportunity has arisen to transition life-saving technologies into more cost-effective versions of existing technologies. This would not only allow more research into existing fields, but also to ensure that potentially life-saving technologies reach the people that need them. / Ph. D.

Genteknik och Risksamhället. En undersökning om Sveriges förhållande till GMO utifrån ett riskperspektiv under det tidiga 1990-talet. / Gene Technology and the Risk Society. A study of Sweden’s relationship with GMOs from a risk perspective during the early 1990’s

Wägander, Fredrik January 2015 (has links)
The purpose of this thesis is to analyse Sweden’s first GMO-legislation which was implemented in 1994. The legislation was created because of Swedens commitment to the EES-agreement, but also because of the necessity for GMO-legislation. The analysis is based on Ulrich Beck’s theory which stipulates that highly developed societies are no longer industrial societies but instead have become risk societies, which also has a connection to and is strongly influenced by the precautionary principle. In a risk society the logic of risk production dominates the logic of wealth production and the regulations and actions of governments correlate to this perspective. The questions the analysis seeks to answer are how the actors involved in the making of Sweden’s first comprehensive GMO-legislation has considered, judged and finally chosen to handle the potential risks associated with gene technology. The results show that Sweden had a distinctive focus on risk, which also had a strong connection to ethics, which in the end was about how big of a risk could be accepted based on the moral resonsibility for the environment. In some parts Sweden took the restrictions further than required for by the EES-agreement based on the risk approach. The legislation can be characterized as being surrounded by an epistemological problem, due the lack of definitive knowledge about GMOs at the time. These results also support the view found by earlier research, when it comes to how Sweden has handled the issues surrounding GMOs during an early stage. / Uppsatsens syfte är att utifrån ett riskperspektiv analysera Sveriges första heltäckande GMO-lagstiftning vilken antogs 1994. Lagstiftningen skapades som ett resultat av Sveriges åtaganden via EES-avtalet, men också utifrån nödvändigheten av att skapa en heltäckande GMO-lag. Undersökningen bygger på Ulrich Becks teori om att välutvecklade samhällen har gått från att vara industrisamhällen till att bli risksamhällen. I risksamhället dominerar riskproduktionens logik över rikedomsproduktionens logik där regeringars och myndigheters agerande styrs utifrån detta perspektiv. Frågor som undersökningen söker svar på är hur de aktörer som var inblandade i skapandet av Sveriges första heltäckande GMO-lag resonerat kring, bedömt och slutligen hanterat de risker som ansågs finnas med gentekniken. Resultatet visar att Sverige hade ett uttalat fokus på risker som i förlängningen går tillbaka till etiska frågor, där vilka risker som kunde accepteras utifrån det moraliska ansvaret för miljön stod i centrum. I vissa delar så införde Sverige en striktare lagstiftning än vad EES-avtalet krävde utifrån ett riskperspektiv. Lagstiftningen kan sägas ha karaktäriserats av ett epistemologiskt problem, vilket var en följd av den okunskap som förelåg vid tidpunkten. Detta stödjer också den tidigare forskningens uppfattningar kring hur Sverige hanterat frågan med GMO på ett tidigt stadium.
