OES Faculty Publications

Diazotrophic marine cyanobacteria in the genus Trichodesmium contribute a large fraction of the new nitrogen entering the oligotrophic oceans, but little is known about how they respond to shifts in global change variables such as carbon dioxide (CO₂) and temperature. We compared Trichodesmium dinitrogen (N₂) and CO₂ fixation rates during steady-state growth under past, current, and future CO₂ scenarios, and at two relevant temperatures. At projected CO₂ levels of year 2100 (76 Pa, 750 ppm), N₂ fixation rates of Pacific and Atlantic isolates increased 35-100%, and CO₂ fixation rates increased 15-128% …

Physiochemical Indicators Of Single Walled Carbon Nanotube Toxicity, Alan Casey

Doctoral

Numerous toxicity studies have been conducted to date both in vivo and in vitro on refined and raw Single Walled Carbon Nanotubes (SWCNT). Differences in SWCNT toxicity and biocompatibility have been observed between these studies, and whilst these discrepancies have been attributed to factors such as varying percentages of remnant catalytic particles, differences in dispersion methods etc. the mechanisms underlying these inconsistencies have not been investigated. This study used standard spectroscopic and cellular techniques to elucidate the origins of these inconsistencies and also to estimate the validity of toxicological data evaluated form standard cytotoxic endpoints. Spectroscopic studies were conducted in …

Value-At-Risk In It Services Contracts, Robert J. Kauffman, Ryan Sougstad

Research Collection School Of Computing and Information Systems

As information systems (IS) and technology solutions become increasingly service-driven, managers are faced with the task of choosing parameters such as service-levels, pricing, and contract duration. Information technology (IT) services vendors manage portfolios of contracts in which parameters, decided at inception, are often subject to future risks. The contract profit maximization decision may adversely affect the risk position of the firm's portfolio of services contracts. We propose a model to inform vendors on setting optimal parameters for IS contracts subject to acceptable levels of risk. The analytic model presented draws from IS economics research and the principles of value-at-risk (VaR) …

National Culture And Its Effects On Knowledge Communication In Online Virtual Communities, Keng Siau, Fiona Fui-Hoon Nah, Min Ling

Research Collection School Of Computing and Information Systems

Online virtual communities provide a powerful means of knowledge sharing. Despite the prevalence of online virtual communities, there is a paucity of research to investigate the effect of national culture differences on knowledge sharing in online virtual communities. Are there differences between online virtual communities from different national cultures? This research studies the differences in knowledge-sharing activities between US-based and China-based online virtual communities. Hofstede's dimensions of national culture serve as the theoretical foundation for this research.

The Law And Policy Beginnings Of Ecosystem Services, James Salzman, J.B. Ruhl

Faculty Scholarship

This article is an introduction to a symposium issue of the journal on ecosystem services. As the brief descriptions of recent developments make clear, the field has changed greatly since the late 1990s and there are a lot of exciting developments underway. With the partnership of the Journal of Land Use & Environmental Law, we thought it important to revisit the state of the field five years after the Stanford workshop. Thus we invited experts across the range of environmental law to Florida State for a two-day workshop assessing the current status of ecosystem services in environmental law. The results …

Research Collection School Of Computing and Information Systems

Applications leveraging network presence in next-generation cellular networks have so far focused on subscription queries, where "presence" information is extracted from specific devices and sent to entities who have subscribed to such presence information. In this article we present BusinessFinder, a service that leverages the underlying cellular presence substrate to provide efficient, on-demand, context-aware matching of customer requests to nomadic micro businesses as well as small and medium businesses having a mobile workforce. Presence, in the context of BusinessFinder, is not simply limited to phone location and device status, but also encompasses dynamic attributes of vendors (both "mobile" and "static"), …

Changing Transitions To Adulthood In Vietnam's Remote Northern Uplands: A Focus On Ethnic Minority Youth And Their Families, Bussarawan Teerawichitchainan, Hac Van Vinh, Nguyen Thi Phuong Lan

Research Collection School of Social Sciences

Vietnam’s rapid economic growth has provided young Vietnamese new opportunities unheard of in their parents’ generation. This is, however, not the case for ethnic minority youth. Many of them are among the poorest, least healthy, and least educated. Ethnic minorities, who tend to live in remote mountainous areas, account for 15 percent of Vietnam’s 84 million total population and, according to a recent estimate, 61 percent of them are poor. Evidence suggests that despite recent efforts of the Government of Vietnam in promoting poverty reduction in remote areas, a majority of ethnic minorities have not yet experienced positive change, contrary …

Nationalism, Civilization, And Transnational Relations: The Discourse Of Greater China, William A. Callahan

Research Collection School of Social Sciences

This essay examines the interplay between nationalism and foreign policy in China—but with a twist. It seeks to loosen up analytical categories to expand from cultural nationalism to see how civilization constructs identity in national and transnational ways. It examines the limits of Chinese trans/nationalism according to the main Chinese expression of inside/outside—‘civilization/barbarism’—as it constructs Chinese nationalism and Greater China. The purpose is to both critically examine Chinese nationalism and to trace what our focus on the nation-state obscures: namely, transnational politics. Rather than recounting one master narrative of Chinese nationalism, the essay argues that civilization and barbarian define Greater …

Mate Preference Necessities In Long- And Short-Term Mating: People Prioritize In Themselves What Their Mates Prioritize In Them, Norman P. Li

Research Collection School of Social Sciences

People were given highly constrained low budgets of mate dollars to allocate across various characteristics pertaining to their ideal partners and to their ideal selves for long- and short-term mating. First, results replicated findings from LI et al. (2002) and LI and KENRICK (2006). For ideal long-term mates, men prioritized physical attractiveness and women prioritized social status. For ideal short-term mates, both sexes prioritized physical attractiveness. Second, people's design of their ideal selves mirrored what the opposite sex ideally desired in their mates. For a long-term mating context, men prioritized social status in themselves and women prioritized physical attractiveness in …

Globalization, The Developmental State, And The Politics Of Urban Growth In Korea: A Multilevel Analysis, Yooil Bae, Jefferey M. Sellers

Research Collection School of Social Sciences

This article explores the politics of urban growth in a transitional society. Korea, which is experiencing rapid industrialization, urbanization and democratic transition exemplifies a set of conditions that may seem to favor the emergence of an urban growth politics and business-led growth coalition much like that found in urban areas at the time of industrialization, and still prevalent in much of the US and other western democracies today. Yet our multilevel case analyses show that the transformations in Korea as a late industrializer, late democratizer and late adopter of urban policy have helped to consolidate more restricted policies toward urban …

The Gunman In Blacksburg, Michael R. Hill

Department of Sociology: Faculty Publications

TWODAYSAGO, on Monday morning, April 16, while this class was in session, a lethal, hypermodern tragedy was unfolding on the campus of Virginia Polytechnic Institute, more commonly known today as Virginia Tech. The precise details of the deadly episode in Blacksburg are still preliminary and will undoubtedly be clarified in the coming days. What we do know is that a disturbed young man, a fully-credentialed college senior, shot and killed some thirty persons—black and white, classmates and instructors—and seriously wounded dozens more. He then took his own life. The shooter employed small, industrially-produced, rapid-firing handguns. It was an horrific happening, …

Adolescent Sexual Onset: An Intergenerational Analysis, Katherine Johnson, Kimberly A. Tyler

Department of Sociology: Faculty Publications

Adolescents have begun to initiate sexual activity at increasingly early ages in the past few decades. Using a sample of 2,494 adolescents from the National Longitudinal Survey of Youth (NLSY97), structural and parental process variables were examined in the prediction of sexual onset. Results indicated that the age at which youth initiate sexual intercourse is related to the structural characteristics of their grandmothers and mothers, as well as puberty, gender, and race. There is support for partial mediation of the effects of these grandmother characteristics via mother characteristics and parental process. Results are discussed within the framework of the life …

On-Line Preconcentration And Speciation Of Chromium By An 8-Hydroxyquinoline Microcolumn Immobilized On Surfactant-Coated Alumina And Flow Injection Atomic Absorption Spectrometry, Seyyed Hamid Ahmadi, Ali Mohammad Haji Shabani, Shayessteh Dadfarnia, Masoumeh Taei

Turkish Journal of Chemistry

An on-line technique for the determination of chromium species with atomic absorption spectrometry is described. The method is based on separation and preconcentration of Cr(III) on a microcolumn of immobilized 8-hydroxyquinoline on surfactant-coated alumina. The adsorbed analyte is then eluted with 400 \mu L of 20% ethanolic solution of 1.5 mol L^{-1} hydrochloric acid and is transported to a flame atomic absorption spectrometer for quantification. The effects of pH, sample and eluent flow rate, sorption capacity, and the presence of various cations and anions on the sorption of Cr(III) were investigated. The sorption was quantitative in the pH 6-8 range, …

Voltammetric And Spectroscopic Studies Of Vanadium(V)-- Nicotinamide Interactions At Physiological Ph, Semi̇ha Çakir, Ender Bi̇çer

Turkish Journal of Chemistry

The interaction of nicotinamide (NA) with NH_4VO_3 at the physiological pH (pH 7.4) was studied by voltammetry and UV-Vis spectroscopy. The reduction of V(V) ions complexed with NA in phosphate buffer (pH 7.4) was observed as a well-defined reversible reduction peak at --0.35 V. The stoichiometric (metal:ligand) ratio of the complex of V(V) with NA was determined as 1:2 by the mole ratio method.

Hydrothermal Synthesis, Characterization And Photocatalytic Activity Of Nanosized Tio_2 Based Catalysts For Rhodamine B Degradation, Funda Sayilkan, Meltem Asi̇ltürk, Şadi̇ye Şener, Sema Erdemoğlu, Murat Erdemoğlu, Hi̇kmet Sayilkan

Turkish Journal of Chemistry

Nanosize crystalline TiO_2 and SiO_2/TiO_2 mixed oxide particles as a photocatalyst for rhodamine B dye (RB) degradation in aqueous media were synthesized by a hydrothermal process at 200 °C. They were characterized using XRD, SEM, FT-IR, UV/VIS and BET analysis. The effects of silica content on the crystallinity and photocatalytic activity of TiO_2 were investigated. Photocatalytic activity of the nano-TiO_2 was compared with that of SiO_2/TiO_2 mixed oxides at the same conditions for degradation of RB, and mixed oxide catalysts showed more effective catalytic activity than the TiO_2. The results revealed that photodegradation of RB proceeds by pseudo-first-order reaction kinetics …

Synthesis And Characterization Of Polyimides Prepared From Optically Active (R,R) And (S,S)-1,3-Bis(P-N,N´-Dimethylaminobenzyl)-Perhydrobenzimidazol-2-Thion, Murat Yi̇ği̇t, Turgay Seçki̇n, Süleyman Köytepe, Engi̇n Çeti̇nkaya

Turkish Journal of Chemistry

This paper presents the synthesis and characterization of polyimides containing a chiral (R,R) or (S,S) 1,3-bis(p-N,N´-dimethylaminobenzyl)-perhydrobenzimidazol-2-thion unit in the backbone. The reactions occur between equimolar amounts of a dianhydride and an aromatic dimethylamine in the presence of the solvent N-methyl-2-pyrollidone (NMP). In this work, the chiral monomer RR and SS -1,3-bis(p-N,N´-dimethylaminobenzyl)-perhydrobenzimidazol- 2-thion were used as diamines. The polyimides obtained were characterized by thermogravimetry (TGA), differential thermal analysis (DTA), differential scanning calorimeter (DSC), infrared spectroscopy (FT-IR), and gel permeation chromatography (GPC). It was found that the composition of the polymer had a significant effect upon the thermal behavior of the material.
