Satellite servicing is a high priority task for NASA and the space industry, addressing the needs of a variety of missions, and potentially lowering the overall cost of missions through refurbishment and reuse. However, the ability to service satellites is severely limited by the lack of long reach manipulation capability and inability to launch new devices due the end of the Space Transport Sy...

UNLABELLED Biologists routinely use Microsoft Office applications for standard analysis tasks. Despite ubiquitous internet resources, information needed for everyday work is often not directly and seamlessly available. Here we describe a very simple and easily extendable mechanism using Web Services to enrich standard MS Office applications with internet resources. We demonstrate its capabiliti...

In this paper we analyze the source and level of the marketing gains when structured debt securities are sold at yields that reflect only their credit ratings, or specifically at the yield on an equivalently rated reference bond. We distinguish between credit ratings that are based on probabilities of default and ratings that are based on the expected default losses. We show that the marketing ...

Code cloning is one of the most well-known codelevel technical debts. In this paper, I discuss when, why and for whom practitioners detect code clones based on my experience of industry/university collaboration. At first, I introduce five project instances based on my experience. Next, I identify elements of the context model of a software maintenance project. After that, I discuss the impact o...

Using data from the 2001 Survey of Consumer Finances, this study examines how the holding of types and amounts of household debt changes over the life cycle. The results show that the likelihood of holding each type of debt and the amount of each type of debt compared to total assets decrease with age. Although the popular press has speculated that older households accumulate excessive amounts ...

We examine the optimal mixture and priority structure of bank and market debt using a trade-off model in which banks have the unique ability to renegotiate outside formal bankruptcy. Flexible bank debt offers a superior trade-off between tax shields and bankruptcy costs. Ease of renegotiation limits bank debt capacity, however. Optimal debt structure hinges upon which party has bargaining power...

The fiscal theory says that the price level is determined by the ratio of nominal debt to the present value of real primary surpluses. I analyze long-term debt and optimal policy in the fiscal theory. I find that the maturity structure of the debt matters. For example, it determines whether news of future deficits implies current inflation or future inflation. When long-term debt is present, th...

Emerging market countries increasingly issue nominal government debt. At the same time, these countries experience sovereign debt crises with default and high inflation. This paper studies the implications of debt denomination for sovereign default and inflation policies. Using bond-level data on government borrowing, I show that default and inflation rates vary systematically with debt denomin...

Financial debt in young people has increased in recent years. Because debt may have severe consequences, and it may enhance criminal behavior, insight into the prevalence and determinants of debt and its association with crime is important. We conducted a systematic review and meta-analysis of 36 manuscripts to examine the prevalence of financial debt (k = 23), correlates and risk factors of de...
