The Ecology Of Interorganizational Information Sharing, Jane Fedorowicz, Janis L. Gogan, Amy W. Ray

Journal of International Technology and Information Management

Increasingly, companies use interorganizational information systems to support business process partnerships, such as automatic replenishment systems and other supply chain initiatives, invoicing and payments, and insurance claims processing. Inter-firm networking in turn can increase the visibility of information generated and used by business partners. These business partners may experience intended and unintended impacts from the changes in the partnering relationship, in effect altering the ecology of the organization. Yet IT researchers rarely study an organization’s ecology, focusing instead on impacts upon internal processes. Our goal in this paper is to propose a definition of interorganizational information ecology, to provide IT …

A Conceptual Framework For E-Branding Strategies In The Non-Profit Sector, Horst Treiblmaier, Irene Pollach, Arne Floh

Journal of International Technology and Information Management

E-branding provides non-profit organizations (NPOs) with new opportunities to communicate their missions, which is of paramount importance in a market segment that competes for donations and voluntary labor. Since successful e-branding is determined by both internal and external communication strategies, we developed a framework which explains the interdependency of these two factors in NPOs. Our findings are based on qualitative interview data and a website analysis of eleven Austrian NPOs. The NPOs' internal and external e-communication strategies are categorized into three successive levels each and combined in a two-dimensional grid, which shows how NPOs integrate their communication strategies.

Two Developing Countries With Two Different Economic Results: A Comparative Study Of Thailand & Morocco, Debora J. Gillard

Journal of International Technology and Information Management

After visiting Thailand in 1996 and Morocco in 2001, it was very evident that these two countries had many similarities. Both countries are ruled by monarchs, both are developing countries, and both have overcome many adversities. However, today we find these two countries are very different in their involvement in the global community and in their local economic development. This paper is a study of similarities and differences in the development of Thailand and Morocco which has resulted in the current economic status.

Building Relationships That Last: Integrating Public Relations Into Web Design, Richard V. Mccarthy, Jay E. Aronson, Robert Petrausch

Journal of International Technology and Information Management

This paper explores the relationship between web site design, public relations strategy, and a consumer’s intention to return to a web site. This relationship is defined through a model that explores the influence of information satisfaction, particularly when the web site design is congruent with the consumer’s expectations. The public relations dimension extends the consumer web site design model by interjecting a long-term focus on relationship building that organizations will need to make electronic commerce a viable investment in information technology resources. This is significant because it recognizes the importance of developing loyalty and trust online.

Studying The Value Of Information Sharing In E-Business Supply Chain Management, Aryya Gangopadhyay, Zhensen Huang

Journal of International Technology and Information Management

The supply chain management of goods and services involves multiple trading partners such as raw-material suppliers, manufacturers, distributors, and retailers. Every one of these trading partners need to determine their requirements, in terms of merchandise, and match them against availability, pricing, and cost of transportation. At every step of the supply chain economics information retrieval is a crucial and recurring process. In this paper we study information sharing as a strategy for improved decision making that can increase the profitability of the entire supply chain. We describe various different models for information sharing and illustrate the benefits of information sharing …

Improving Workflow In Home Healthcare Industry: A Case Study, Mohan Rao, Norma Teran, Michael Savard

Journal of International Technology and Information Management

Home healthcare industry is facing increasing pressure to change business processes and manage information flow electronically. With the help of a case example, this paper describes how a web- based system could improve the workflow communication problems in home healthcare companies. Every department of the case company has its own software to assist in everyday operations but is unable to communicate with one another electronically. All documents necessary in the coordination of care have to move physically between departments. The proposed solution is a web-based electronic form management system that would improve regulatory compliance and operating efficiency.

Early Sexual Abuse, Street Adversity, And Drug Use Among Female Homeless And Runaway Adolescents In The Midwest, Xiaojin Chen, Kimberly A. Tyler, Les B. Whitbeck, Dan R. Hoyt

Department of Sociology: Faculty Publications

Research on homeless and runaway adolescents has shown that this population is at high risk for illicit drug use. Though sexual abuse has been widely considered in the etiology of illicit drug use, we know less about how early sexual abuse affects young people’s decisions to run away, to use drugs, and to engage in other deviant behavior on the streets. Based on interviews with 361 female homeless and runaway adolescents in four midwestern states, the current study revealed a high prevalence of drug use, especially use of cocaine among youths with sexual abuse histories. Path analyses showed that early …

Optimization Of Conditions For Studies Of Protein Unfolding By Hydrogen Exchange/Mass Spectrometry, A.S. Raza, David L. Smith

Department of Chemistry: Faculty Publications

Understanding the forces driving protein folding and aggregation is an essential step in developing means for controlling these important processes. Amide hydrogen exchange, coupled with mass spectrometry, has become an important method for studying protein unfolding and refolding. To extend procedures developed to study unfolding of relatively soluble proteins to less soluble, aggregation-prone proteins requires special considerations. This publication describes a general strategy developed using yeast transaldolase, which aggregates easily under conditions required to study its unfolding. Results presented here show that reducing the protein concentration to the nanomolar range is essential for managing aggregation of transaldolase. In addition, the …

Ecological Effects Of Transgenic Crops And The Escape Of Transgenes Into Wild Populations, Diana Pilson, Holly R. Prendeville

School of Biological Sciences: Faculty Publications

Ecological risks associated with the release of transgenic crops include nontarget effects of the crop and the escape of transgenes into wild populations. Nontarget effects can be of two sorts: (a) unintended negative effects on species that do not reduce yield and (b) greater persistence of the crop in feral populations. Conventional agricultural methods, such as herbicide and pesticide application, have large and well- documented nontarget effects. To the extent that transgenes have more specific target effects, transgenic crops may have fewer nontarget effects. The escape of transgenes into wild populations, via hybridization and introgression, could …

Recognition And Development Of Hope For South African Organizational Leaders, Fred Luthans, René Van Wyk, Fred Walumbwa

Department of Management: Faculty Publications

The significant challenges faced by South Africa at present are well known. How to deal with the problems from a political and economic perspective abound, but taking a psychological approach has been neglected. This paper proposes a positive approach to South African organizational leadership based on the psychological capacity of hope. After giving a brief background on the context surrounding South African organizations, the theory, research, and application of hope relevant to organizational leadership in the “Rainbow Nation” are presented and analyzed. Such an overlooked positive approach represented by hopeful organizational leaders seems needed at this juncture of South Africa’s …

Human, Social, And Now Positive Psychological Capital Management: Investing In People For Competitive Advantage, Fred Luthans, Carolyn M. Youssef

Department of Management: Faculty Publications

There is growing evidence that human resources are crucial to organizational success, and may offer the best return on investment for sustainable competitive advantage. Jeffery Pfeffer’s extensive work, summarized in his book The Human Equation, discusses substantially supported but unfortunate findings that only about half of today’s organizations and their managers believe that human resources really do matter. Moreover, only half of those organizations act upon their beliefs beyond paying lip service to this vital resource. Few organizations have adopted high performance work practices, such as 360-degree feedback, pay-for-performance, self-managed teams, employee empowerment, and other human-oriented initiatives. Furthermore, Pfeffer shows …

Unlocking The Mask: A Look At The Process By Which Authentic Leaders Impact Follower Attitudes And Behaviors, Bruce Avolio, William L. Gardner, Fred Walumbwa, Fred Luthans, Douglas R. May

Department of Management: Faculty Publications

The conceptual and empirical links between authentic leadership and follower attitudes, behaviors, and performance outcomes have not been fully developed. Although we have a number of articles developing the theory of authentic leadership and testing propositions that will appear in a forthcoming special issue of The Leadership Quarterly (Vol. 16, Issue 3, 2005), the focus of this article is to provide some of the initial foundation work for the broader theoretical framework of how authentic leaders influence follower attitudes, behaviors, and performance. Here, we draw from positive organizational behavior, trust, hope, emotion, identification, and identity theories to describe the processes …

Deletion Of The Δ12-Oleic Acid Desaturase Gene Of A Nonaflatoxigenic Aspergillus Parasiticus Field Isolate Affects Conidiation And Sclerotial Development, Perng Kuang Chang, Richard A. Wilson, Nancy P. Keller, Thomas E. Cleveland

Fungal Molecular Plant-Microbe Interactions

Aims: To investigate how linoleic acid affects conidial production and sclerotial development in a strictly mitotic Aspergillus parasiticus field isolate as related to improving biocompetitivity of atoxigenic Aspergillus species.

Methods and Results: We disrupted A. parasiticus Δ12-oleic acid desaturase gene (odeA) responsible for the conversion of oleic acid to linoleic acid. We examined conidiation and sclerotial development of SRRC 2043 and three isogenic mutant strains deleted for the odeA gene (DodeA), either with or without supplementing linoleic acid, on one complex potato dextrose agar (PDA) medium and on two defined media: nitrate-containing Czapek agar (CZ) and Cove’s ammonium …

Characterization Of The Aspergillus Parasiticus Δ12-Desaturase Gene: A Role For Lipid Metabolism In The Aspergillus–Seed Interaction, Richard A. Wilson, Ana M. Calvo, Perng-Kuang Chang, Nancy P. Keller

Fungal Molecular Plant-Microbe Interactions

In the mycotoxigenic oilseed pathogens Aspergillus flavus and Aspergillus parasiticus and the model filamentous fungus Aspergillus nidulans, unsaturated fatty acids and their derivatives act as important developmental signals that affect asexual conidiospore, sexual ascospore and/or sclerotial development. To dissect the relationship between lipid metabolism and fungal development, an A. parasiticus Δ¹²-desaturase mutant that was unable to convert oleic acid to linoleic acid and was thus impaired in polyunsaturated fatty acid biosynthesis was generated. The Δ¹²-desaturase mutant demonstrates delayed spore germination, a twofold reduction in growth, a reduced level of conidiation and complete loss of sclerotial …

A Consensus Protocol For The Determination Of The Threshold Doses For Allergenic Foods: How Much Is Too Much?, S. L. Taylor, S. L. Hefle, C. Bindslev-Jensen, F. M. Atkins, C. Andre, C. Bruijnzeel-Koomen, A. W. Burks, R. K. Bush, M. Ebisawa, P. A. Eigenmann, A. Host, Jonathan O. B. Hourihane, E. Isolauri, D. J. Hill, A. Knulst, G. Lack, H. A. Sampson, D. A. Moneret-Vautrin, F. Rance, P. A. Vadas, J. W. Yunginger, R. S. Zeiger, J. W. Salminen, C. Madsen, P. Abbott

Department of Food Science and Technology: Faculty Publications

Background:While the ingestion of small amounts of an offending food can elicit adverse reactions in individuals with IgE-mediated food allergies, little information is known regarding these threshold doses for specific allergenic foods. While low-dose challenge trials have been conducted on an appreciable number of allergic individuals, a variety of different clinical protocols were used making the estimation of the threshold dose very difficult.

Objective: A roundtable conference was convened to develop a consensus clinical protocol for low-dose challenge trials for the estimation of threshold doses for specific allergenic foods.

Methods: In May 2002, 20 clinical allergists and other interested parties …

Genetic Identification Of Spotted Owls, Barred Owls, And Their Hybrids: Legal Implications Of Hybrid Identity, Susan M. Haig, Thomas D. Mullins, Eric D. Forsman, Pepper W. Trail, Liv Wennerberg

United States Geological Survey: Staff Publications

Recent population expansion of Barred Owls (Strix varia) into western North America has led to concern that they may compete with and further harm the Northern Spotted Owl (S. occidentalis caurina), which is already listed as threatened under the U.S. Endangered Species Act (ESA). Because they hybridize, there is a legal need under the ESA for forensic identification of both species and their hybrids. We used mitochondrial control-region DNA and amplified fragment-length polymorphism (AFLP) analyses to assess maternal and biparental gene flow in this hybridization process. Mitochondrial DNA sequences (524 base pairs) indicated large divergence between …

Use Of Radar Remote Sensing (Radarsat) To Map Winter Wetland Habitat For Shorebirds In An Agricultural Landscape, Oriane W. Taft, Susan M. Haig, Chris Kiilsgaard

United States Geological Survey: Staff Publications

Many of today’s agricultural landscapes once held vast amounts of wetland habitat for waterbirds and other wildlife. Successful restoration of these landscapes relies on access to accurate maps of the wetlands that remain. We used C-band (5.6-cm-wavelength), HH-polarized radar remote sensing (RADARSAT) at a 38° incidence angle (8-m resolution) to map the distribution of winter shorebird (Charadriiformes) habitat on agricultural lands in the Willamette Valley of western Oregon. We acquired imagery on three dates (10 December 1999, 27 January 2000, and 15 March 2000) and simultaneously collected ground reference data to classify radar signatures and evaluate map accuracy …

Defeating Diplostomoid Dangers In Usa Catfish Aquaculture, Robin M. Overstreet, Stephen S. Curran

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Diplostomoid digenean metacercariae have caused widescale mortalities of channel catfish, Ictalurus punctatus (Rafinesque), at aquaculture farms in Louisiana, Mississippi and Arkansas, USA. Originally, based on a tentative diagnosis, the industry considered the primary harmful agent to be an introduced species from Europe, Bolbophorus confusus (Krause, 1914), frequently reported from the American white pelican, Pelecanus erythrorhynchos Gmelin. Our group has now shown, using ITS 1-2 plus three more-conservative gene fragments, that two sympatric species of Bolbophorus exist in the American white pelican. One, B. damnificus Overstreet et Curran, 2002, infects the musculature of catfish, and the other, probably not B. confusus …

Aminoacyl-Trnas: Setting The Limits Of The Genetic Code, Michael Ibba, Dieter Söll

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Aminoacyl-tRNAs (aa-tRNAs) are simple molecules with a single purpose—to serve as substrates for translation. They consist of mature tRNAs to which an amino acid has been esterified at the 3′-end. The 20 different types of aa-tRNA are made by the 20 different aminoacyl-tRNA synthetases (aaRSs, of which there are two classes), one for each amino acid of the genetic code (Ibba and Söll 2000). This would be fine if it were not for the fact that such a straightforward textbook scenario is not true in a single known living organism. aa-tRNAs lie at the heart of gene expression; they interpret …
