Journal of International Technology and Information Management

A key challenge to top management is the alignment of IS and business plans for the purpose of producing an IT-based competitive advantage. This study uses a well known communication theory to provide new insight into the impact of CEO and CIO planning participation on IS and business alignment via the convergence of views between the CEO and CIO regarding the current and future strategic impact of IT on the firm’s success. One hundred and nine matched pairs of questionnaire responses from CIOs and CEOs were collected using a postal survey. Results indicated that CIO participation in business planning predicted …

A Comprehensive Study On The Differences In Erp Implementation Between Manufacturing And Service Industry, Farshad Salimi, Ben Dankbaar, Reggie Davidrajuh

Journal of International Technology and Information Management

In the first part, this paper presents a review of current literatures on key critical success factors (KCSFs) and their inevitable relative links with ERP benefits, project (strategic) goals and objectives in ERP implementation; this literature review searches for the available KCSFs in two sectors: manufacturing and service industry. The second part of paper looks into the available literature on differences in manufacturing and service industry. From these differences we deduct that there are differences in ERP implementation between manufacturing and services.

A Framework For Agents Conducting E-Business In A Supply Chain, C.W. Leung, T.N. Wong, Domenic Sculli

Journal of International Technology and Information Management

This paper describes the development of an agent-based framework that supports the purchasing function in supply chain management. The framework has been applied in a case situation for planned order releasing from a manufacturer’s materials requirement planning (MRP) system. The proposed framework incorporates a negotiation protocol that can effectively coordinate the negotiation process between a buyer agent and several supply agents, which may represent the manufacturer and its suppliers respectively. These agents negotiate according to their preferred strategies which aim to conclude a deal that achieves their own objectives. The implementation of the negotiation process involves considerations of the price …

Access To Computer Technologies At Home Improves Wages In The Marketplace, Pankaj Kumar Maskara, Rajesh Aggarwal, Rajesh Maskara

Journal of International Technology and Information Management

This study suggests that having access to a computer and the Internet at home leads to better wages. We normally have the idea that people with higher wages have computers and Internet access at home. But with declining prices of home PCs and the increasing importance of Internet, this no longer seems to be the case. The new owners of PC today are considerably poorer and less educated than in the past. People with access to a PC and Internet at home appear to earn 8.6% more than their counterpart. This result seems to suggest that University policies requiring students …

Descriptive data are presented along with a first-order and a second-order factor analysis.

Organizational Learning Stages Of Assimilation, Integration And Optimization And Their Relationship With User Satisfaction Of Enterprise Resource Planning Systems, Edith Galy, Jane Lemaster

Journal of International Technology and Information Management

Literature on organizational learning suggests that various processes have to occur in order for an organization to learn. This study provides empirical evidence for measuring organizational learning in three stages: assimilation, integration and optimization. A path model of organizational learning was tested establishing the significance and magnitude of the total effect of assimilation, integration and optimization on the satisfaction level of top information executives in firms with Enterprise Resource Planning systems. The model indicates that the optimization-satisfaction path is the strongest, followed by the integration-satisfaction path. Measuring and improving the factors composing organizational learning is essential for successful implementation of …

Interrelationships Among Language Skills, Externalizing Behavior, And Academic Fluency And Their Impact On The Academic Skills Of Students With Ed, J. Ron Nelson, Gregory J. Benner, Stern Neill, Scott A. Stage

Department of Special Education and Communication Disorders: Faculty Publications

There is growing interest in understanding the factors that influence the academic achievement of students with emotional disturbance (ED). Structural equation modeling was used to test the interrelationships among language skills, externalizing behavior, and academic fluency and their impact on the academic skills of students with ED. Results showed that language skills exerted a significant proximal effect and distal effect on academic skills. The effect of language skills was mediated through academic fluency (path coefficient = .389) but also had a proximal effect on academic skills (path coefficient = .359). However, externalizing behavior failed to have a statistically significant effect …

Coordinative Organization Of Lingual Propulsion During The Normal Adult Swallow, Erin M. Wilson, Jordan R. Green

Department of Special Education and Communication Disorders: Faculty Publications

Lingual propulsion during swallowing is characterized by the sequential elevation of the anterior, middle, and dorsal regions of the tongue. Although lingual discoordination underlies many swallowing disorders, the coordinative organization of lingual propulsion during the typical and disordered swallow is poorly understood. The purpose of this investigation was to quantitatively describe the coordinative organization of lingual propulsion during the normal adult swallow. Tongue movement data were obtained from the X-Ray Microbeam Database at the University of Wisconsin. Movement of four pellets placed on specific tongue regions were tracked in 36 healthy adult participants while they swallowed 10 cc of water …

Towards Monitoring Galileo: The European Gnss Supervisory Authority In Statu Nascendi = Zur Künftigen Überwachungsagentur Des Galileo Systems, Vers Une Autorité De Surveillance Du Système Galileo, Frans G. Von Der Dunk

Space, Cyber, and Telecommunications Law Program: Faculty Publications

There is little doubt that one of the most interesting and revolutionary, but also complicated and challenging space projects of today is Galileo, Europe’s own full-fledged second-generation navigation satellite system. Developed jointly by the European Union through the Commission and the European Space Agency, Galileo should by the end of the decade have thirty operational satellites in middle-earth-orbits providing timing, positioning and navigation signals across the globe.

From the very beginning Galileo was envisaged in particular by the Commission as a public-private-partnership (PPP). On the one hand, a private concessionaire should operate the system as of full operational capability (originally …

Potential Added Value Of Psychological Capital In Predicting Work Attitudes, Milan Larson, Fred Luthans

Department of Management: Faculty Publications

Meeting the challenge of effectively managing human resources requires new thinking and approaches. To extend the traditional perspective of economic capital, increasing recognition is being given to human capital and more recently social capital, this article proposes and empirically tests the potential added value that psychological capital may have for employee attitudes of satisfaction and commitment. After first providing the background and theory of PsyCap, this article reports a study of manufacturing employees (N = 74) that found a significant relationship between PsyCap and job satisfaction (r=.373) and organization commitment (r=.313). Importantly, the employees’ PsyCap had a significant added impact …

Privies And Parasites: The Archaeology Of Health Conditions In Albany, New York, Charles L. Fisher, Karl Reinhard, Matthew Kirk, Justin Divirgilo

Karl Reinhard Publications

Large numbers of parasites were identified in archaeological samples collected from privies and other features in excavations in Albany, New York. This information provides the largest database available for the study of parasite infections in historical period American cities. The greatest numbers of parasites were in contexts related to the expansion of the city in the late-18th century. Parasites remained, but their quantities decreased in the 19th century during another period of rapid population growth. The city was able to control parasite infection during this period through several means, including new techniques of privy construction, new water supply systems, and …

Differentiating Phonotactic Probability And Neighborhood Density In Adult Word Learning, Holly L. Storkel, Jonna Armbrüster, Tiffany Hogan

Department of Special Education and Communication Disorders: Faculty Publications

Purpose: The purpose of this study was to differentiate effects of phonotactic probability, the likelihood of occurrence of a sound sequence, and neighborhood density, the number of words that sound similar to a given word, on adult word learning. A second purpose was to determine what aspect of word learning (viz., triggering learning, formation of an initial representation, or integration with existing representations) was influenced by each variable.
Method: Thirty-two adults were exposed to 16 nonwords paired with novel objects in a story context. The nonwords orthogonally varied in phonotactic probability and neighborhood density. Learning was measured following 1, 4, …

A Cool Eastern Pacific Ocean At The Close Of The Last Interglacial Complex, Daniel R. Muhs, Kathleen R. Simmons, George L. Kennedy, Kenneth R. Ludwig, Lindsey T. Groves

United States Geological Survey: Staff Publications

New high-precision thermal ionization mass-spectrometric (TIMS) U-series ages of solitary corals (Balanophyllia elegans) from several marine terrace localities along the California and southern Oregon coasts date to the ~80,000 yr BP high stand of sea, correlative with marine isotope substage 5a, late in the last interglacial complex. Ages of multiple corals from localities north of Point Año Nuevo (central California) and San Nicolas Island (southern California) suggest that this high sea stand could have lasted at least 8000 yr, from ~84,000 to ~76,000 yr BP. These ages overlap with those from marine deposits on tectonically stable Bermuda and …

Abundance And Distribution Of Selected Elements In Soils, Stream Sediments, And Selected Forage Plants From Desert Tortoise Habitats In The Mojave And Colorado Deserts, Usa, M. A. Chaffee, K. H. Berry

United States Geological Survey: Staff Publications

A baseline and background chemical survey was conducted in southeastern California, USA, to identify potential sources of toxicants in natural and anthropogenically-altered habitats of the threatened desert tortoise (Gopherus agassizii). Soil, stream sediment, and plant samples were collected from six tortoise habitat study areas in the Mojave and Colorado deserts and analysed for up to 66 different elements. The chemical analyses provided new information on the abundances and distributions of selected elements in this region. Soil, stream-sediment, and plant analyses showed distinct variations in bulk chemistries from locality to locality. Variations were, in general, consistent with the many …

Use Of Mammal Manure By Nesting Burrowing Owls: A Test Of Four Functional Hypotheses, Matthew D. Smith, Courtney J. Conway

United States Geological Survey: Staff Publications

Animals have evolved an impressive array of behavioural traits to avoid depredation. Olfactory camouflage of conspicuous odours is a strategy to avoid depredation that has been implicated only in a few species of birds. Burrowing owls, Athene cunicularia, routinely collect dried manure from mammals and scatter it in their nest chamber, in the tunnel leading to their nest and at the entrance to their nesting burrow. This unusual behaviour was thought to reduce nest depredation by concealing the scent of adults and juveniles, but a recent study suggests that manure functions to attract arthropod prey. However, burrowing owls routinely …

Landscape Context Mediates Influence Of Local Food Abundance On Wetland Use By Wintering Shorebirds In An Agricultural Valley, Oriane W. Taft, Susan M. Haig

United States Geological Survey: Staff Publications

While it is widely understood that local abundance of benthic invertebrates can greatly influence the distribution and abundance of wetland birds, no studies have examined if wetland landscape context can mediate this relationship. We studied the influence of wetland food abundance and landscape context on use of agricultural wetlands by wintering dunlin (Calidris alpina) and killdeer (Charadrius vociferus) in the Willamette Valley of Oregon, USA, over two winters (1999–2000, 2000–2001) of differing rainfall and subsequent habitat distribution. We monitored bird use (frequency of occurrence and abundance) at a sample of wetlands differing in local food abundance …

Redescription Of Cryptocotyle Thapari Mcintosh, 1953 (Trematoda: Heterophyidae), In The River Otter Lutra Longicaudis From Bolivia, Scott Lyell Gardner, Peter T. Thew

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cryptocotyle thapari McIntosh, 1953 (Digenea: Heterophyidae), collected originally from a South American otter that died at the U.S. National Zoo in Washington, D.C., is redescribed from specimens obtained from a river otter, Lutra longicaudis, collected from the Rı´o Matos in the Departamento de Beni, Bolivia. These individuals of C. thapari are slightly smaller than the type specimens, but they have similar features, including testes arranged in tandem and a well-defined ventrogenital sac. We redescribe this species because the original description was based on only 3 individuals, and the figures lacked detail. This is the first record of Cryptocotyle from …

Asymmetry Of Processing Trade In China : Theory And Empirics, Zhaopeng Xing

Dissertations and Theses Collection (Open Access)

This paper studies decision of whether outsourcing or localization in China. Both strategies can enjoy low wage advantage. But outsourcing induces processing trade, while localization, which has additional localization cost can turn processing trade of some goods to ordinary trade. The asymmetric effect lies on that once localized, it is hard to return to outsourcing due to competition or fixed expenditures involved. If wage difference larger, it is more preferable to localized. Therefore, we can expect asymmetric effect of processing trade due to movement of relative wage difference, which was proved by econometrics on recent data by cointegrating analysis within …

Information Value Of Credit Ratings In Asia Ex-Japan Markets, Chen Zhou

Dissertations and Theses Collection (Open Access)

This study investigates the information value of credit ratings by exploring the relationship between ratings and security price. Unlike previous studies, we concentrate on the major markets ex-Japan in Asia. We begin with an investigation of rating reclassification as well as credit watch placement events by three leading international rating agencies. We show that markets with differing level of sophistication behave differently. Specifically, South Korea and Hong Kong are found to respond in a similar manner. Indonesia shows possible ign of information leakage. In the cases of Malaysia and Thailand, significant and positive equity price responses exist for upgrades, suggesting …

Flexibilization, Globalization, And Privatization: Three Challenges To Labour Rights In Our Time, Katherine V. W. Stone

Osgoode Hall Law Journal

Three dynamics are coalescing to reshape labour relations in the twenty-first century in the United States: They are flexibilization, globalization, and privatization. Flexibilization refers to the changing work practices by which firms no longer use internal labour markets or implicitly promise employees lifetime job security, but rather seek flexible employment relations that permit them to increase or diminish their workforce, and reassign and redeploy employees with ease. Globalization refers to the increase in cross-border transactions in the production and marketing of goods and services that facilitates firm relocation to low labour cost countries. And privatization refers to the rise of …

Human Rights And Transnational Culture: Regulating Gender Violence Through Global Law, Sally Engle Merry

Osgoode Hall Law Journal

In the current era of human rights activism, the global production of human rights approaches to violence against women generates a wide variety of localization processes. Activists translate between global discourses and local contexts and meanings. Culture is conceptualized in quite different and sometimes contradictory ways in this process. Essentialized ideas of culture inhibit recognition of the potential contributions of local cultural practices and provide justifications for groups to resist these changes. This article shows, with reference to a case study of Fiji, that a more anthropological conception of culture provides a better picture of the localization process and foregrounds …

Modal Logic In Computer Science, Leigh Lambert

Theses

Modal logic is a widely applicable method of reasoning for many areas of computer science. These areas include artificial intelligence, database theory, distributed systems, program verification, and cryptography theory. Modal logic operators contain propositional logic operators, such as conjunction and negation, and operators that can have the following meanings: "it is necessary that," "after a program has terminated," "an agent knows or believes that," "it is always the case that," etc. Computer scientists have examined the difficulty of problems in modal logic, such as satisfiability. Satisfiability determines whether a formula in a given logic is satisfiable. The complexity of satisfiability …

A Meaningful Md5 Hash Collision Attack, Narayana D. Kashyap

Master's Projects

It is now proved by Wang et al., that MD5 hash is no more secure, after they proposed an attack that would generate two different messages that gives the same MD5 sum. Many conditions need to be satisfied to attain this collision. Vlastimil Klima then proposed a more efficient and faster technique to implement this attack. We use these techniques to first create a collision attack and then use these collisions to implement meaningful collisions by creating two different packages that give identical MD5 hash, but when extracted, each gives out different files with contents specified by the atacker.

Scalable Energy-Efficient Routing In Mobile Ad Hoc Network, Rashmi Kukanur

Master's Projects

The quick deployment without any existing infrastructure makes mobile ad hoc networks (MANET) a striking choice for dynamic situations such as military and rescue operations, disaster recovery, and so on and so forth. However, routing remains one of the major issues in MANET due to the highly dynamic and distributed environment. Energy consumption is also a significant issue in ad hoc networks since the nodes are battery powered. This report discusses some major dominating set based approaches to perform energy efficient routing in mobile ad hoc networks. It also presents the performance results for each of these mentioned approaches in …

Enhancing Tcp Performance In Wired-Cum-Wireless Networks, Shruthi B. Krishnan

Master's Projects

Increasing popularity for mobile devices has prompted industrial and academic research towards improving the performance of wireless applications. Transmission Control Protocol (TCP) plays an important role in defining a network’s performance, and its use in wireless networks has exposed several inadequacies in its operation. Tight coupling of TCP’s error and congestion control mechanisms has proven to be incompatible with the unique characteristics of wireless channels. TCP, designed for wired networks, assumes any loss of packet to be an indication of congestion in the network. Wireless networks exhibit a higher bit error rate, low and varying bandwidth, and disconnections of hosts …
