The thermogravimetric analysis on TaC, HfC, and their solid solutions has been carried out in air up to 1400 ◦C. Three solid solution compositions have been chosen: 80TaC-20 vol % HfC (T80H20), 50TaC-50 vol % HfC (T50H50), and 20TaC-80 vol % HfC (T20H80), in addition to pure TaC and HfC. Solid solutions exhibit better oxidation resistance than the pure carbides. The onset of oxidation is delaye...

Recent transport measurements [Churchill et al. Nature Phys. 5, 321 (2009)] found a surprisingly large, 2-3 orders of magnitude larger than usual (13)C hyperfine coupling (HFC) in (13)C enriched single-wall carbon nanotubes. We formulate the theory of the nuclear relaxation time in the framework of the Tomonaga-Luttinger liquid theory to enable the determination of the HFC from recent data by I...

Patterns of mental health are clearly associated with life circumstances, including educational and economic opportunities, access to safe and supportive neighborhoods, socially structured exposures to stressors and to supportive relationships. In this article, we examine the social and economic correlates of depressive symptoms among African American women residing within a predominantly Afric...

There is ample empirical evidence documenting widespread financial illiteracy and limited pension knowledge. At the same time, the net worth distribution is heavily dispersed and many workers arrive on the verge of retirement with little or no personal wealth. This paper is the first to investigate the relation between financial sophistication and household net worth relying on specific measure...

This study isolates the causal effects of financial literacy and schooling on wealth accumulation using a new household dataset and an instrumental variables (IV) approach. Financial literacy and schooling attainment are both strongly positively associated with wealth outcomes in linear regression models, whereas the IV estimates reveal even more potent effects of financial literacy. They also ...

BACKGROUND AND OBJECTIVES This paper focuses on the inadequate attention on women's non-maternal healthcare in low- and middle-income countries. The study assessed the purchase of and financial access to non-maternal healthcare. It also scoped for mainstreaming household financial resources in this regard to suggest for alternatives. METHODS A household survey through multi-stage stratified s...

In the past 20 years the economy of the Czech Republic has experienced substantial changes. In the 1990s the development was affected by the transformation which sought to establish the right conditions for privatization and creation of elementary market relations. In the last decade the characteristic elements such as private ownership and corresponding institutional framework have been streng...

We analyze the impact of cognitive skills on two specific examples of consumer financial decisions where suboptimal behavior is well defined: first, the use of a credit card for a transaction after making a balance transfer on the account, and second, cases where individuals are penalized for inaccurate estimation of the value of one’s home on home equity loan or line of credit application. We ...
