A MODEL OF LOW-RISK PIRACY
Title
A MODEL OF LOW-RISK PIRACY.
Creator
Camilo, Amil, Burguet, Roberto, University of Central Florida
Abstract / Description
Heterogeneous consumers make the decision to buy a durable good or to download a replica, and a monopolist chooses to price and protect their intellectual property in the form of an authentication cost. An optimal price and authentication cost is derived, and shown to be higher than the efficient outcome for a uniform distribution of consumers. The optimal selection of price and protection are shown to be commensurate with his authenticating technology, and the searching ability of consumers....
Show moreHeterogeneous consumers make the decision to buy a durable good or to download a replica, and a monopolist chooses to price and protect their intellectual property in the form of an authentication cost. An optimal price and authentication cost is derived, and shown to be higher than the efficient outcome for a uniform distribution of consumers. The optimal selection of price and protection are shown to be commensurate with his authenticating technology, and the searching ability of consumers. As an extension, a layout for a monopolist problem where consumers have different searching abilities is shown to be indistinct from a homogeneous case when consumers are uniformly distributed.

Abstract / Description
A paradigm shift from static spectrum allocation to dynamic spectrum access (DSA) is becoming a reality due to the recent advances in cognitive radio, wide band spectrum sensing, and network aware real--time spectrum access. It is believed that DSA will allow wireless service providers (WSPs) the opportunity to dynamically access spectrum bands as and when they need it. Moreover, due to the presence of multiple WSPs in a region, it is anticipated that dynamic service pricing would be offered...
Show moreA paradigm shift from static spectrum allocation to dynamic spectrum access (DSA) is becoming a reality due to the recent advances in cognitive radio, wide band spectrum sensing, and network aware real--time spectrum access. It is believed that DSA will allow wireless service providers (WSPs) the opportunity to dynamically access spectrum bands as and when they need it. Moreover, due to the presence of multiple WSPs in a region, it is anticipated that dynamic service pricing would be offered that will allow the end-users to move from long-term service contracts to more flexible short-term service models. In this research, we develop a unified economic framework to analyze the trading system comprising two components: i) spectrum owner--WSPs interactions with regard to dynamic spectrum allocation, and ii) WSP--end-users interactions with regard to dynamic service pricing. For spectrum owner--WSPs interaction, we investigate various auction mechanisms for finding bidding strategies of WSPs and revenue generated by the spectrum owner. We show that sequential bidding provides better result than the concurrent bidding when WSPs are constrained to at most single unit allocation. On the other hand, when the bidders request for multiple units, (i.e., they are not restricted by allocation constraints) synchronous auction mechanism proves to be beneficial than asynchronous auctions. In this regard, we propose a winner determination sealed-bid knapsack auction mechanism that dynamically allocates spectrum to the WSPs based on their bids. As far as dynamic service pricing is concerned, we use game theory to capture the conflict of interest between WSPs and end--users, both of whom try to maximize their respective net utilities. We deviate from the traditional per--service static pricing towards a more dynamic model where the WSPs might change the price of a service almost on a session by session basis. Users, on the other hand, have the freedom to choose their WSP based on the price offered. It is found that in such a greedy and non-cooperative behavioral game model, it is in the best interest of the WSPs to adhere to a price threshold which is a consequence of a price (Nash) equilibrium. We conducted extensive simulation experiments, the results of which show that the proposed auction model entices WSPs to participate in the auction, makes optimal use of the common spectrum pool, and avoids collusion among WSPs. We also demonstrate how pricing can be used as an effective tool for providing incentives to the WSPs to upgrade their network resources and offer better services.

Show moreFor millennia, money has been a basal element of everyday life reality in market-organized societies. Albeit money has changed extrinsically (e.g., form, use, utility) countless of times, some intrinsic characteristics remain the same, i.e., money is reified value. But why? What gives money value? Even more crucial, what is money in the first place? This exploratory study delves into the intricacies of money, in particular the revolutionary 21st century pecuniary techno-phenomenon, a cryptocurrency called Bitcoin. Though cryptocurrencies have been the topic of several financial and legal scholarly publications for a few years, we rather focus our analysis on Bitcoin's ontological characteristics under a schema of overlapping theoretical layers: Social Exchange Theory, Marxian Dialectics, and Social Construction of Reality. Our intention is to dissect Bitcoin sociologically and empirically examine its global exchange, consumption, and institutionalization. Consequently, we venture to ask, can Bitcoin redefine the meaning of money and how we relate to it? Reformulate the role of banking? Disrupt the universally accepted objective reality of currency value attached to sensorial experience? Transfer trust from ambivalent human relations to an incorruptible algorithm? Or even become (")the Internet of money(")?

Abstract / Description
This dissertation addressed the need for empirical research on the leadership of multinational virtual teams (Davis & Bryant, 2003; Early & Gibson, 2002; Ilgen, Lepine, and Hollenbeck, 1997; Prieto & Arias, 1997), particularly in the field of educational leadership (Cheng, 1995).

Show moreThis dissertation addressed the need for empirical research on the leadership of multinational virtual teams (Davis & Bryant, 2003; Early & Gibson, 2002; Ilgen, Lepine, and Hollenbeck, 1997; Prieto & Arias, 1997), particularly in the field of educational leadership (Cheng, 1995). This was accomplished through the development of a model based upon the cultural values discovered through the use of Hofstede's (1980, 2001) Values Survey Module 94 (VSM 94). As workers will bring values from their own cultures to the multinational workplace (Bochner & Hesketh, 1994), research was conducted to determine the cultural values of economics professors in the United States and Germany in order to formulate a cultural contingent leadership model based on Triandis' (1993) adaptation of Fiedler's (1967) contingency theory. Given a total response from 194 U.S. and German economics professors, it was discovered that faculty in both the United States and Germany had values that differed significantly from those that Hofstede discovered for his IBM employee samples in four out of five dimensions. However, it was found that the values for the U.S. and German faculties were a close replication of Hoppe's (1990) findings which were based on a sample that was similar to the economics faculties in both occupation and education. These findings add a cautionary note to the recommendation by Hofstede and Peterson (2000) that existing cultural values can be used by cultural researchers: Previous cultural value data can be used if the samples are closely matched to the previous samples in both nationality as well as educational and occupational background. The research thus indicated that differences in national culture, as measured by Hofstede's (1980, 2001) cultural dimensions, still exist. In addition, a direct comparison of the cultural values between the two faculties indicated that the U.S. and German economics faculties differed significantly in two of Hofstede's cultural dimensions, individualism and collectivism and masculinity and femininity. The two samples were not significantly different in the cultural dimensions of power distance, uncertainty avoidance, and long term orientation. Using the Triandis (1993) approach, application of the research results to Fiedler's (1967) LPC model indicated that a relationship oriented leader would be an in-match leader for a group of U.S. and German higher education economics faculty. This result was contingent upon the cultural values discovered for the U.S. and German faculties who would be involved in an endeavor with situational variables similar to that which would be found in an international joint venture to offer online distance economics education to students in a developing country.

Show moreLatin America is a region that has deep roots in Spanish colonialism. Since its independence, many countries in the region have heavily depended on agriculture exports to industrialized states to support their economies. This has led to political theorists to label Latin America as an area full of periphery countries that are exploited for resources by core countries. Costa Rica, Panama, and Nicaragua were not the exception. In recent years, however, a noticeable difference between the economies of the countries has helped Costa Rica and Panama become more successful than Nicaragua, on the basis of GDP, GNI, and other similar measures. This thesis attempts to explain this economic difference by analyzing what type of relationship the three countries have had with the United States (which has acted as a regional hegemon) and analyzing how each country has handled economic dependence on agriculture. Through this comparative case study, the thesis tries to add to development and dependency theory literature.

Show moreThe number of students enrolling in Advanced Placement (AP) classes has been increasing in Florida and across the nation over the last decade. However, this trend is not happening for traditionally underserved groups of students such as African Americans, Hispanics, and students from low socioeconomic backgrounds. These minority groups are underrepresented in AP classes, while Asian and White students are overrepresented. This trend is alarming because there are qualified minority students who have a great chance of being successful in AP classes according to AP Potential(TM) data. For some reason though, these qualified minority and low income students are nevertheless not enrolling in AP classes. The purpose of this research was to investigate whether or not the extension of inviting messages to enroll in AP courses was dependent upon students' ethnic and/or socioeconomic background. A mixture of quantitative and qualitative research methods were employed to examine how the role of invitational theory affects minority student enrollment in AP classes. Mean scale scores from a survey were used to measure student attitudes about how welcoming and inviting schools were when it came to student recruitment into AP classes. T-tests and an analysis of variance were used to determine if there were differences in attitudes among students currently enrolled in AP classes, students of various economic means, and students of various ethnicities. Results from this study found that students already in AP classes felt very invited to challenge themselves in AP classes by teachers, administrators, parents, and peers. Richer students, Whites, and Asians also felt more invited to join AP classes than did poorer, African American, and Hispanic students, though these results were not statistically significant. To increase enrollment in AP classes, the overwhelming response from students was that schools should advertise the pros and cons of taking an AP class. Future research should examine students' perspectives regarding inviting school cultures in regions outside of the southeastern United States. Researchers should also focus on students in urban high schools as previous research has only examined student attitudes in rural and suburban high schools. Finally, future research should examine inviting school cultures from other stakeholders' perspectives such as parents and teachers.

Show moreRobots have been a part of the imagination of Western culture for centuries. The possibility for automation and artificial life has inspired the curiosity of thinkers like Leonardo Da Vinci who once designed a mechanical knight. It wasn't until the 19th century that automated machinery has become realized. The confrontation between human and automation has inspired a fear, referred to as (")technopanic("), that has been exacerbated in tandem with the evolution of technology. This thesis seeks to discover the historical precedence for these fears. I explore three modes of knowledge (Philosophy, Economics, and Film Theory) to examine the agendas behind the messages on the topic of Artificial Life, specifically Robots. I then advocate for an alternative philosophy called Post-Humanism. I argue that what is needed to alleviate the fears and anxieties of Western culture is a shift in how humanity views itself and its relation to the natural world. By structuring my thesis in this way, I identify the roots of Western humanity's anthropocentric ontology first, explore the economic implications of automation second, analyze the cultural anticipations of artificial life in Western media third, and finally offer an alternative attitude and ethic as a way out of the pre-established judgments that do little to protect Western culture from E.A.I.
