External inverse-Compton emission from blazar jets
According to leptonic models for the high-energy emission from blazars, relativistic electrons in the inner jets inverse-Compton scatter photons from a variety of sources. Seed photons are certainly introduced via the synchrotron process from the electrons themselves, but external sources of seed photons may also be present. In this paper, we present detailed derivations of the equations describing external inverse-Compton scattering from two sources of seed photons: direct emission from the accretion disk, and accretion disk photons that have scattered off the broad line region. For each source, we derive the seed photon spectrum incident on the jet, the single electron energy loss rate, and the emitted photon spectrum.

Surgical Management of Massive Labial Edema in a Gravid Preeclamptic Diabetic
Background. Massive labial edema is a rare complication during pregnancy that can jeopardize vaginal delivery, as well as leading to maternal and fetal morbidity. It can be related to systemic pathologies, but has been commonly associated with preeclampsia and diabetes. This increased and sometimes longstanding pressure may result in a “labial compartment syndrome� leading to microvascular damage and tissue necrosis if not resolved in a timely fashion. Case. Massive labial edema was treated first conservatively and then surgically in a gravid diabetic patient with severe preeclampsia. Immediately after Cesarean section, the labial compartment syndrome was relieved surgically and resolved rapidly. Conclusion. When conservative attempts at management of labial edema fail, or rapid resolution is critical to maternal and fetal outcome, surgical alternatives should be considered
Self-Efficacy
The study of self-efficacy is concerned with understanding this important aspect of self and identity—people\u27s beliefs about their personal capabilities and how these beliefs influence what they try to accomplish, how they try to accomplish it, and how they react to successes and setbacks along the way
Modeling Creativity For The Multinational Firm
Much has been written about the proliferation of the modern multinational corporation (MNC) as a primary driver of globalization [Bhagwati, 2004; Rugman and Verbeke 2004; Wolf. 2004]. A common theme shared by all MNCs expanding into foreign markets is the notion of how best to manage the knowledge assets of the firm from all perspectives in order to achieve maximum performance while concomitantly increasing the ability of the firm to innovate while expanding. This paper examines the processes of idea creation within multinational corporations in parallel with the role that information and communication technology (ICT) plays as a driver of that innovation
Impact of Immigrant Entrepreneurs and Workers in Leisure and Hospitality Businesses: Massachusetts and New England
This report examines the role and impact of immigrant entrepreneurs and workers on Leisure and Hospitality businesses in New England, particularly Massachusetts. A significant portion of state economies in New England, especially in Massachusetts, relies heavily on the employment of the foreign-born. As the native workforce ages and population growth declines, businesses are becoming increasingly dependent upon the availability of the foreign-born. This development has facilitated an increasingly significant presence and role of immigrant entrepreneurs in Leisure and Hospitality businesses that is documented for the first time in this report
Alcoholic liver disease: Is acetaminophen safe?
Yes, "acetaminophen is a safe and effective analgesic that can be appropriately used for adult patients with stable chronic alcoholic liver disease for at least a short period of time (studies have been limited to a maximum of 48-72 hours), up to the maximum recommended dosage of 4 g daily (strength of recommendation: A, based on 2 RCTs and other studies). There are little data to guide longer-term use of acetaminophen in this situation
