An International Survey on Advanced Practice Nursing Education, Practice, and Regulation

Abstract: Purpose: To describe international trends on the developing role of the nurse practitioner-advanced practice nurse (NP-APN), including nomenclature, levels and types of NP-APN education, practice settings, scope of practice, regulatory policies, and political environment. Design: A cross-sectional, descriptive Web-based survey sent in February and March 2008 to a total of 174 key informants and active members of the International Nurse Practitioner-Advanced Practice Nursing Network of the International Council of Nurses. Methods: An international Web-based survey preceded by a pilot survey. Findings: Ninety-one nurses from 32 countries responded. Thirteen titles were identified on nomenclature for the NP-APN in different countries. NP-APN education was available in 71% of the 31 countries responding to this item, with 50% identifying the master's degree as the most prevalent credential. Twenty-three countries had formal recognition of the NP-APN role. Of these, 48% had licensure maintenance or renewal requirements for the NP-APN, with most requiring continuing education or clinical practice. The greatest support for the NP-APN role came from domestic nursing organizations (92%), individual nurses (70%), and the government (68%), while opposition came primarily from domestic physician organizations (83%) and individual physicians (67%). Conclusions: Interest in the NP-APN role has been gaining ground worldwide. This study presents a snapshot of education, practice, and regulation for NP-APNs as they develop their unique role in delivering health care in various countries. Areas that may require more support are highlighted. Clinical Relevance: The NP-APN role in healthcare systems is expanding and will benefit from international networking and support.

Supplier Encroachment under Asymmetric Information

Abstract: Prior literature has shown that, for a symmetric information setting, supplier encroachment into a reseller's market can mitigate double marginalization and benefit both the supplier and the reseller. This paper extends the investigation of supplier encroachment to the environment where the reseller might be better informed than the supplier. We find that the launch of the supplier's direct channel can result in costly signaling behavior on the part of the reseller, in which he reduces his order quantity when the market size is small. Such a downward order distortion can amplify double marginalization. As a result, in addition to the "win-win" and "win-lose" outcomes for the supplier and the reseller, supplier encroachment can also lead to "lose-lose" and "lose-win" outcomes, particularly when the reseller has a significant efficiency advantage in the selling process and the prior probability of a large market is low. We further explore the implications of those findings for information management in supply chains. Complementing the conventional understanding, we show that with the ability to encroach, the supplier may prefer to sell to either a better informed or an uninformed reseller in different scenarios. On the other hand, as a result of a supplier developing encroachment capability, a reseller either may choose not to develop an advanced informational capability, or may become more willing to find a means of credibly sharing his information.The appendices for this paper are available at the following URL: http://ssrn.com/abstract=2340117

DNA-bridged carbon nanotube arrays

Abstract: A class of biological sensing devices that include a substrate comprising an array of carbon nanotubes (CNTs) to which are chemically attached biological molecules is disclosed. The attached biological molecules are capable of electrical conductivity that is responsive to chemical changes occurring as a result of their interaction with target species. A means for means for using DNA as a material of potential in molecular electronic sensor devices, being primarily based on molecular electron-transfer reaction processes between DNA-binding donors and acceptors is also disclosed, including composition, method of manufacture and their use are described.
