'Only in the leap from the lion's head will he prove his worth':natural law and international relations

This article argues the benefits of including a theological interpretation of natural law morality within the normative discourses of international politics. It challenges the assumption of a Grotian secular natural law arguing that practical reason, in a Thomist interpretation, is better suited to the demands of international political theory. It engages with themes of agency, practical reason, and community in order to enhance the content of the post-territorial community evidenced in ethical cosmopolitan debates. Likewise, it envisions a simultaneously enhancing a rapprochement among cosmopolitan and communitarian discourses of international politics facilitated through an institutional design guided by the morality of natural law.

A stepwise fuzzy linear programming model with possibility and necessity relations

Linear programming (LP) is the most widely used optimization technique for solving real-life problems because of its simplicity and efficiency. Although conventional LP models require precise data, managers and decision makers dealing with real-world optimization problems often do not have access to exact values. Fuzzy sets have been used in the fuzzy LP (FLP) problems to deal with the imprecise data in the decision variables, objective function and/or the constraints. The imprecisions in the FLP problems could be related to (1) the decision variables; (2) the coefficients of the decision variables in the objective function; (3) the coefficients of the decision variables in the constraints; (4) the right-hand-side of the constraints; or (5) all of these parameters. In this paper, we develop a new stepwise FLP model where fuzzy numbers are considered for the coefficients of the decision variables in the objective function, the coefficients of the decision variables in the constraints and the right-hand-side of the constraints. In the first step, we use the possibility and necessity relations for fuzzy constraints without considering the fuzzy objective function. In the subsequent step, we extend our method to the fuzzy objective function. We use two numerical examples from the FLP literature for comparison purposes and to demonstrate the applicability of the proposed method and the computational efficiency of the procedures and algorithms. © 2013-IOS Press and the authors.

Engaging autobiography:mobility trauma and international relations

This article outlines the possibilities of autobiographical stories to criticize status quo iterations of International Relations (IR). The article draws on the personal experiences of the author’s deportation order issued by the United Kingdom’s Home Office and its associated Border Agency (UKBA) to challenge the accepted assumptions of a cosmopolitan worldview as it relates to orderly international institutional design. It highlights the possibilities of trauma when border management and personal mobility collide. It suggests that mobility trauma ensues when the expectations of human mobility, outlined in Article 13 of the Universal Declaration of Human Rights, infringe the state’s role as security provider. It begins in part one with a challenge to the traditional role and understanding of international borders that sustain order within the international. It examines the unacknowledged role that human vulnerability plays within IR and institutional design while frankly engaging with human vulnerability and trauma in the second section. This section details the experiences of the author when her mobility rights were curtailed and the ensuing identity crisis prompted by such events. The final section investigates the ideas of critical cosmopolitan scholarship demanding that such discourses acknowledge and work through the possibility of failed agency when the demands of state security supersede individual mobility rights. It turns to the possibility of traumatic iterations of IR in order to probe such possibilities. The article suggests, in its conclusion, the possibility of storytelling and psychoanalysis to endorse unorthodox agency, and the possibility of a dynamic international institutional design, that challenges the status quo iterations of IR.

Marketing-szemléletmód és az üzleti kapcsolatok (Marketing-outlook and business relations)

A cikk az üzleti kapcsolatok marketingértelmezéséről szól. A marketing a piaci magatartás tudománya. A két vagy több partner között megvalósuló piaci tranzakció a marketing alapvető elemzési egysége. A piac dinamikáját a tranzakciók ismétlődései jelentik. Az ismétlődő tranzakciókból épülnek fel a piaci kapcsolatok.. A szervezetközi piac a gazdasági és nem gazdasági szereplők egymással kölcsönös függőségben lévő, a társadalmi környezetbe beágyazott kapcsolatrendszere, amelyben a tevékenységek és az erőforrások cseréje zajlik. A cikk kitér annak rövid bemutatására, hogy a különböző marketingterületek miként járulnak hozzá az üzleti kapcsolatok megismeréséhez. A szerző meghatározása szerint az üzleti kapcsolat az üzleti hálózatba ágyazott két szervezet közötti interaktív cserekapcsolatot jelent. A definíció kifejtése során bemutatásra kerülnek az üzleti kapcsolatok érintettjei, legfontosabb folyamatai, valamint a kapcsolat létének néhány következménye. __________ The article discusses the interpretation of business relations within the field of marketing. Marketing is the science of market behaviour. The basic segment of marketing analysis is the market transaction between two or more persons. The dynamics of the market is created by the repetition of transactions. Repeated transactions make market relations. Inter-organizational market is a network of interdependent relations among economic and non-economic actors embedded into the social environment, serving as a platform for the exchange of actions and resources. The article shortly describes how the different areas of marketing contribute to the knowledge of business relations. According to the author, business relations are interactive exchange relations between two organizations embedded in the business network. The detailed explanation of the definition introduces the parties involved in business relations, the most important processes, and some consequences of the existence of the relation.

Tree Islands in Everglades Landscapes: Current Status, Historical Changes, and Hydrologic Impacts on Population Dynamics and Moisture Relations, First Annual Report

In 2005 we initiated a project designed to better understand tree island structure and function in the Everglades and the wetlands bordering it. Focus was on the raised portions at the upstream end of the islands, where tropical hardwood species adapted to well-drained conditions usually are the most prominent component of the vegetation. The study design is hierarchical, with four levels; in general, a large number of sites is to be surveyed once for a limited set of parameters, and increasingly small sets of islands are to be sampled more intensively, more frequently, and for more aspects of ecosystem function. During the first year of the 3-year study, we completed surveys of 41 Level 1 (i.e., the least intensive level) islands, and established permanent plots in two and three islands of Levels 2 and 4 intensity, respectively. Tree species richness and structural complexity was highest in Shark Slough “hammocks”, while islands in Northeast Shark Slough and Water Conservation Area 3B, which receive heavy human use, were simpler, more park-like communities. Initial monitoring of soil moisture in Level 4 hammocks indicated considerable local variation, presumably associated with antecedent rainfall and current water levels in the adjacent marsh. Tree islands throughout the study area were impacted significantly by Hurricanes Katrina and Wilma in 2005, but appear to be recovering rapidly. As the project continues to include more islands and repeated measurements, we expect to develop a better grasp of tree island dynamics across the Everglades ecosystem, especially with respect to moisture relations and water levels in the adjacent marsh. The detailed progress report which follows is also available online at http://www.fiu.edu/~serp1/projects/treeislands/tree_islands_2005_annual_report.pd

"New" Social Movements: Alternative Modernities, (Trans)local Nationalisms, and Solidarity Economies

My dissertation is the first project on the Haitian Platform for Advocacy for an Alternative Development- PAPDA, a nation-building coalition founded by activists from varying sectors to coordinate one comprehensive nationalist movement against what they are calling an Occupation. My work not only provides information on this under-theorized popular movement but also situates it within the broader literature on the postcolonial nation-state as well as Latin American and Caribbean social movements. The dissertation analyzes the contentious relationship between local and global discourses and practices of citizenship. Furthermore, the research draws on transnational feminist theory to underline the scattered hegemonies that intersect to produce varied spaces and practices of sovereignty within the Haitian postcolonial nation-state. The dissertation highlights how race and class, gender and sexuality, education and language, and religion have been imagined and co-constituted by Haitian social movements in constructing ‘new’ collective identities that collapse the private and the public, the rural and the urban, the traditional and the modern. My project complements the scholarship on social movements and the postcolonial nation-state and pushes it forward by emphasizing its spatial dimensions. Moreover, the dissertation de-centers the state to underline the movement of capital, goods, resources, and populations that shape the postcolonial experience. I re-define the postcolonial nation-state as a network of local, regional, international, and transnational arrangements between different political agents, including social movement actors. To conduct this interdisciplinary research project, I employed ethnographic methods, discourse and textual analysis, as well as basic mapping and statistical descriptions in order to present a historically-rooted interpretation of individual and organizational negotiations for community-based autonomy and regional development.

A Study of Stock Market Fluctuations and their Relations to Business Conditions

Most research on stock prices is based on the present value model or the more general consumption-based model. When applied to real economic data, both of them are found unable to account for both the stock price level and its volatility. Three essays here attempt to both build a more realistic model, and to check whether there is still room for bubbles in explaining fluctuations in stock prices. In the second chapter, several innovations are simultaneously incorporated into the traditional present value model in order to produce more accurate model-based fundamental prices. These innovations comprise replacing with broad dividends the more narrow traditional dividends that are more commonly used, a nonlinear artificial neural network (ANN) forecasting procedure for these broad dividends instead of the more common linear forecasting models for narrow traditional dividends, and a stochastic discount rate in place of the constant discount rate. Empirical results show that the model described above predicts fundamental prices better, compared with alternative models using linear forecasting process, narrow dividends, or a constant discount factor. Nonetheless, actual prices are still largely detached from fundamental prices. The bubble-like deviations are found to coincide with business cycles. The third chapter examines possible cointegration of stock prices with fundamentals and non-fundamentals. The output gap is introduced to form the non-fundamental part of stock prices. I use a trivariate Vector Autoregression (TVAR) model and a single equation model to run cointegration tests between these three variables. Neither of the cointegration tests shows strong evidence of explosive behavior in the DJIA and S&P 500 data. Then, I applied a sup augmented Dickey-Fuller test to check for the existence of periodically collapsing bubbles in stock prices. Such bubbles are found in S&P data during the late 1990s. Employing econometric tests from the third chapter, I continue in the fourth chapter to examine whether bubbles exist in stock prices of conventional economic sectors on the New York Stock Exchange. The ‘old economy’ as a whole is not found to have bubbles. But, periodically collapsing bubbles are found in Material and Telecommunication Services sectors, and the Real Estate industry group.

Hiearchies of Eating Disorders: Fat-Phobia and Internalized Beauty Ideals in Online Communities

Research and discourse on Eating Disorders (ED) have a tendency to perpetuate certain stereotypes regarding women of color, however unintentional or innocuous it may appear. The research conducted, does show that the prominent ED within communities of minorities or of lower social status is Binge Eating Disorder (BED). A Foucauldian discourse analysis of online forums by young women with ED, such as myproana.com, would be the primary method of documenting how these women form a hierarchy of the community's ED, and analyze if it correlates with the social status primarily associated with the Eating Disorder. Within these forums, and ED based communities, a clear hierarchy is formed, with Anorexia Nervosa at the top and BED at the bottom. From the minimal research available on women of color and ED, it is clear that, for Black women at least, BED is the most common—and thus it is my goal to explore any possible correlation if applicable. Because so little exists that focuses on EDs in women of color, this analysis may help to promote more research in race and class dynamics of Eating Disorders, as well on how those factors affect how women view their own bodies.

Dispersion and energy relations in periodic chains and grids

In this study wave propagation, dispersion relations, and energy relations for linear elastic periodic systems are analyzed. In particular, the dispersion relations for monoatomic chain of infinite dimension are obtained analytically by writing the Block-type wave equation for a unit cell in order to capture the dynamic behavior for chains under prescribed vibration. By comparing the discretized model (mass-spring chain) with the solid bar system, the nonlinearity of the dispersion relation for chain indicates that the periodic lattice is dispersive in contrast to the continuous rod, which is non dispersive. Further investigations have been performed considering one-dimensional diatomic linear elastic mass-spring chain. The dispersion relations, energy velocity, and group velocity have been derived. At certain range of frequencies harmonic plane waves do not propagate in contrast with monoatomic chain. Also, since the diatomic chain considered is a linear elastic chain, both of the energy velocity and the group velocity are identical. As long as the linear elastic condition is considered the results show zero flux condition without residual energy. In addition, this paper shows that the diatomic chain dispersion relations are independent on the unit cell scheme. Finally, an extension for the study covers the dispersion and energy relations for 2D- grid system. The 2x2 grid system show a periodicity of the dispersion surface in the wavenumber domain. In addition, the symmetry of the surface can be exploited to identify an Irreducible Brillouin Zone (IBZ). Compact representations of the dispersion properties of multidimensional periodic systems are obtained by plotting frequency as the wave vector’s components vary along the boundary of the IBZ, which leads to a widely accepted and effective visualization of bandgaps and overall dispersion properties.

A Systematic Review of Race and Ethnicity in Hepatitis C Clinical Trial Enrollment.

The African American/Black population in the United States (US) is disproportionately affected by hepatitis C virus (HCV) and has lower response rates to current treatments. This analysis evaluates the participation of African American/Blacks in North American and European HCV clinical trials. The data source for this analysis was the PubMed database. Randomized controlled clinical trials (RCT) on HCV treatment with interferon 2a or 2b between January 2000 and December 2011 were reviewed. Inclusion criteria included English language and participants 18 years or older with chronic HCV. Exclusion criteria included non-randomized trials, case reports, cohort studies, ethnic specific studies, or studies not using interferon-alfa or PEG-interferon. Of the 588 trials identified, 314 (53.4%) fit inclusion criteria. The main outcome was the rate of African American/ Black participation in North American HCV clinical trials. A meta-analysis comparing the expected and observed rates was performed. Of the RCT's that met search criteria, 123 (39.2%) reported race. Clinical trials in North America were more likely to report racial data than European trials. Racial reporting increased over time. There was a statistically significant difference among the expected and observed participation of African Americans in HCV clinical trials in North America based on the prevalence of this disease within the population. The burden of HCV among African Americans in North America is not reflected in those clinical trials designed to treat HCV. Research on minority participation in clinical trials and how to increase minority participation in clinical trials is needed.

An Exploration of Sociometric Status and Peer Relations in Youth Sport

More than 10 years ago, it was suggested that sociometry and systematic observation were two potentially useful but under-utilized methods for the study of peers in youth sport (Smith, 2003). Despite this call, the methods used to study peers in sport remain largely focused on athletes' perceptions through questionnaires and interviews. Thus, the purpose of this descriptive study was to investigate the utility of sociometry in relation to sport competence and observed athlete behavior in youth sport. Three adolescent female volleyball teams were videotaped during three practice sessions, and sport competence and sociometric status were assessed using questionnaires. An observational coding system was developed and used to code athlete behaviors and data were compared across sociometric status groups. Results revealed significant differences between sociometric status groups on peer ratings of sport competence, but not on athlete behavior. However, interesting findings emerged with respect to how status groups interacted with teammates and coaches. Thus, sport competence seems to be an important factor in gaining acceptance among youth peer groups. Further, sociometry and behavioral observation appear to be useful techniques that should continue to be employed in the study of peer relations in youth sport.
