Transcending Technological Innovation: The Impact Of Acquisitions On Entrepreneurial Technical Organizations, Bruce Crochetiere

Walden Dissertations and Doctoral Studies

Technology firms with substantial cash reserves acquire smaller entrepreneurial firms for diversification. In 2006, 3 large firms acquired 28 organizations, with the combined deals exceeding {dollar}4.7 billion. The problem addressed in this study is that new start-up companies with innovative ideas may not mature when they are acquired by larger companies and do not fully articulate potential industry-transcending innovation. This is important because the unsuccessful integration of an acquisition can dismantle innovation and compromises economic inventiveness. Drawing from the disruptive innovation and the resource-based theories, the purpose of the quasi-experimental study was to examine the impact of acquisition by larger …

Asset Reuse Of Images From A Repository, Deirdre Herman 2011 Walden University

Asset Reuse Of Images From A Repository, Deirdre Herman

Walden Dissertations and Doctoral Studies

According to Markus's theory of reuse, when digital repositories are deployed to collect and distribute organizational assets, they supposedly help ensure accountability, extend information exchange, and improve productivity. Such repositories require a large investment due to the continuing costs of hardware, software, user licenses, training, and technical support. The problem addressed in this study was the lack of evidence in the literature on whether users in fact reused enough digital assets in repositories to justify the investment. The objective of the study was to investigate the organizational value of repositories to better inform architectural, construction, software and other industries whether …

Finding Haystacks With Needles: Ranked Search For Data Using Geospatial And Temporal Characteristics, Veronika Margaret Megler, David Maier

Computer Science Faculty Publications and Presentations

The past decade has seen an explosion in the number and types of environmental sensors deployed, many of which provide a continuous stream of observations. Each individual observation consists of one or more sensor measurements, a geographic location, and a time. With billions of historical observations stored in diverse databases and in thousands of datasets, scientists have difficulty finding relevant observations. We present an approach that creates consistent geospatial-temporal metadata from large repositories of diverse data by blending curated and automated extracts. We describe a novel query method over this metadata that returns ranked search results to a query with …

Real-Time Traffic Estimation Using Data Expansion, Roger LEDERMAN, Laura WYNTER 2011 Singapore Management University

Real-Time Traffic Estimation Using Data Expansion, Roger Lederman, Laura Wynter

Research Collection School Of Computing and Information Systems

This paper presents a method for estimating missing real-time traffic volumes on a road network using both historical and real-time traffic data. The method was developed to address urban transportation networks where a non-negligible subset of the network links do not have real-time link volumes, and where that data is needed to populate other real-time traffic analytics. Computation is split between an offline calibration and a real-time estimation phase. The offline phase determines link-to-link splitting probabilities for traffic flow propagation that are subsequently used in real-time estimation. The real-time procedure uses current traffic data and is efficient enough to scale …

As a result, a survey instrument containing 22 items were retained. Furthermore, …


Efficient Strong Designated Verifier Signature Schemes Without Random Oracle Or With Non-Delegatability, Qiong HUANG, Guomin YANG, Duncan S. WONG, Willy SUSILO 2011 Singapore Management University

Efficient Strong Designated Verifier Signature Schemes Without Random Oracle Or With Non-Delegatability, Qiong Huang, Guomin Yang, Duncan S. Wong, Willy Susilo

Research Collection School Of Computing and Information Systems

Designated verifier signature (DVS) allows a signer to convince a designated verifier that a signature is generated by the signer without letting the verifier transfer the conviction to others, while the public can still tell that the signature must be generated by one of them. Strong DVS (SDVS) strengthens the latter part by restricting the public from telling whether the signature is generated by one of them or by someone else. In this paper, we propose two new SDVS schemes. Compared with existing SDVS schemes, the first new scheme has almost the same signature size and meanwhile, is proven secure …
