Open innovation is increasingly being adopted in business and describes a situation in which firms exchange ideas and knowledge with external participants, such as customers, suppliers, partner firms, and universities. This article extends the concept of open innovation with a push model of open innovation: knowledge is voluntarily created outside a firm by individuals and organisations who proceed to push knowledge into a firm’s open innovation project. For empirical analysis, we examine source code and newsgroup data on the Eclipse Development Platform. We find that outsiders invest as much in the firm’s project as the founding firm itself. Based on the insights from Eclipse, we develop four propositions: ‘preemptive generosity’ of a firm, ‘continuous commitment’, ‘adaptive governance structure’, and ‘low entry barrier’ are contexts that enable the push model of open innovation.

Morbidity and mortality are significant in hemodialysis patients, and every vascular access (VA) is prone to complications - some more, some less. The risk of complications rises from arteriovenous fistulae to arteriovenous grafts and peaks in nontunneled central lines. Strategies to achieve complete evaluation of the patient and precise planning mark the start of successful VA creation. Furthermore, preoperative considerations include safety checklists, team time-out procedures, and antibiotic prophylaxis. Intraoperative technical features and postoperative aspects of documentation and surveillance schemes complete careful and safe VA creation.

Researchers have noted that relationships created between instructors and clients in therapeutic wilderness experiences are unique (Russell, 2003; Russell & Phillips-Miller, 2001; Sklar, Anderson, & Autry, 2007; Taniguchi et al., 2009), but little research has been done to explore these relationships. The present study is an investigation of how instructors build and maintain relationships with participants, conceptualize these relationships, and define success in these tasks. Nine instructors from a wilderness program for at-risk youth participated in interviews. Data were analyzed using a line-by-line coding technique. Results of this study add to existing research on wilderness therapy and therapeutic wilderness experiences, provide models of successful instructing, and guide programs and instructors in the services they provide to their participants.

This presentation was made at the Connecticut State Library Service Center, Willimantic, CT, April 14, 2009. It focused on digital capture workflows for both archival and derivative image creation using accepted current standards. Tools used were inexpensive by choice and focused towards the needs of small to mid-sized cultural heritage institutions who wish to begin digital capture in their own facilities.

The Right to Die Debate is a recent but highly controversial moral matter. In particular, physician-assisted suicide (PAS) is an issue that has been evaded by the medical community for years. As of 1990, most states had never encountered the issue before and therefore did not have any laws in place to prohibit PAS (Strate et. al, 2005). Dr. Jack Kevorkian, a retired pathologist from Royal Oak Michigan was the first to publicly address PAS. He brought the issue into the limelight through a bizarre and crude series of assisted deaths that had a lasting impact on not only the Right to Die Debate as whole, but on public policy and both federal and state governmental agendas. This study focuses on the way in which the media, in particular the New York Times (NYT) has portrayed Dr. Jack Kevorkian as incompetent, morally culpable and in an overall negative light in the past twenty years. Applying Stanley Cohen’s 1972 theory of moral panic, a content analysis of NYT media publications between 1990 and 1999 supports Cohen’s theory and reveals that the media has created a moral panic surrounding Kevorkian. This has in turn led to public policy that prevents both terminally ill individuals and their doctors from having a desirable choice; that of voluntary euthanasia and PAS.

Standard macroeconomic models that assume an exogenous stochastic process for multifactor productivity offer the interpretation that recessions are the result of ''bad news'' (technological regress) and expansions are the result of ''good news'' (technological advancement). The view taken here is that both expansions and recessions are the result of ''good news'' in the sense that in both cases, aggregate production possibilities have increased. Recessions can be thought of as the transition from one technological frontier to the next.

This project involved developing a model for planning a dental emergency treatment center that could function as an embedded component of a shelter for the homeless population. The dental services provided by such a clinic should include treatment for tooth pain, dental caries or cavities, chipped or broken teeth, broken partials, abscessed teeth, emergency cleanings, periodontal disease or gum disease and fillings. These are the dental services that are most often sought by homeless people in hospital emergency rooms.^ The underlying assumption for this project was that the oral health needs of the homeless community can most effectively be addressed by implementing small dental clinics in existing facilities that provide shelter and other services for this population. The model described in this project identifies oral health care services that would be provided by the clinic, facility (physical plant) requirements and associated infrastructure to operate an embedded dental clinic, methods for obtaining funding, strategies of recruiting dental professionals to staff the facility, and methods to assess the outcomes of the embedded clinic strategy. As an example, this project describes a strategy for developing such an embedded clinic at San Antonio Metropolitan Ministries SAMM shelter based on recommendations from community health care leaders, managers of homeless shelters, members of the homeless community and dental professionals^

The Retinoblastoma tumor suppressor gene (RB) plays a role in a variety of human cancers. Experimental analyses have indicated that the protein product of the RB gene (pRb) plays a role in cell cycle regulation, and that this protein is required in cellular differentiation, senescence, and cell survival. pRb function is dependent on its ability to bind to cellular factors. There are multiple protein binding domains within pRb. Mutations within these domains which eliminate the ability of pRb to bind its targets result in loss of function. Loss of pRb function leads to tumorigenesis, although uncontrolled cellular proliferation is not a universal response to pRb inactivation. The ultimate response to the loss of pRb is influenced by both the genetic and epigenetic environments. Targeted disruption of RB in mice results in embryonic lethality, demonstrating the requirement for functional pRb in development. Close examination of various tissues from the embryos which lack wildtype RB shows problems in differentiation as well as showing induction of apoptosis. Although disruption of RB has provided useful information, complete inactivation of a gene precludes the possibility of discovering the functions that separate domains may have within the system. Creation of a dominant negative mutant by domain deletion whose phenotype is expressed in the presence of the wildtype may provide information about the intermediate functions of the protein. In addition, tissue specific targeting of a dominant negative mutant of pRb allows for comprehensive analysis of pRb function in organogenesis. In this thesis, a series of RB deletion mutants were created and tested for dominant negative activity as well as cellular localization. A tissue culture assay for dominant negative activity was developed which screens for the phenotype of apoptosis due to loss of pRb function. Two mutants from this series scored positive for dominant negative activity in this assay. The effect of these mutants within the assay environment can be explained by a model in which pRb acts as a facilitator of cell fate pathway decisions. ^

This study shows that many bad loans now burdening Taiwan's financial institutions are interrelated with the society's democratization which started in the late 1980s. Democratization made the local factions and business groups more independent from the Kuomintang government. They acquired more political influence than under the authoritarian regime. These changes induced them to manage their owned financial institutions more arbitrarily and to intervene more frequently in the state-affiliated financial institutions. Moreover they interfered in financial reform and compelled the government to allow many more new banks than it had originally planned. As a result the financial system became more competitive and the qualities of loans deteriorated. Some local factions and business groups exacerbated the situation by establishing banks in order to funnel funds to themselves, sometimes illegally. Thus many bad loans were created as the side effect of democratization.

This paper presents a micro-model of knowledge creation and transfer in a small group of people. Our model incorporates two key aspects of the cooperative process of knowledge creation: (i) heterogeneity of people in their state of knowledge is essential for successful cooperation in the joint creation of new ideas, while (ii) the very process of cooperative knowledge creation a¤ects the heterogeneity of people through the accumulation of knowledge in common. The model features myopic agents in a pure externality model of interaction. In the two person case, we show that the equilibrium process tends to result in the accumulation of too much knowledge in common compared to the most productive state. Unlike the two-person case, in the four person case we show that the equilibrium process of knowledge creation may converge to the most productive state. Equilibrium paths are found analytically, and they are a discontinuous function of initial heterogeneity.

This paper explores the process of creation of the netbook market by Taiwanese firms as an example of a disruptive innovation by latecomer firms. As an analytical framework, I employ the global value chain perspective to capture the dynamics of vertical inter-firm relationships that drive some firms in the chain to change the status quo of the industry. I then divide the process of the emergence of the netbook market into three consecutive stages, i.e. (1) the launch of the first-generation netbook by a Taiwanese firm named ASUSTeK, (2) the response of the two powerful platform leaders of the industry, Intel and Microsoft Intel, to ASUSTeK’s innovation, and (3) the market entry by another powerful Taiwanese firm, Acer, and explain how Taiwanese firms broke the Intel-centric market and tapped into the market-creating innovation opportunities that had been suppressed by the two powerful platform leaders. I also show that the creation of the netbook industry was an evolutionary process in which a series of responses by different industry players led to changes in the status quo of the industry.
