The Economic Consequences of the Decline of Marriage

The institution of marriage has served to funnel economic resources from fathers to children. Its continued decline in the countries of the developed world threatens the adequacy of the economic support of human reproduction, now increasingly provided by women. Its decline is also probably implicated in the low birth rates now being registered. The rise of cohabitation has not prevented a rise in the proportion of lone parents, and their numbers are growing rapidly. The children of lone parents are relatively deprived, both in terms of income and adults’ time for child care and housekeeping. Government-supported programs in the United States aimed at rescuing marriage have not been proven effective. Ways need to be explored to get a return of men’s economic support for reproduction. But the most likely way of repairing at least some of the damage to children is a big increase in government provision to the entire population of goods and services that children need: health care, high-quality education, child care, decent housing, university education. This will require in most countries a big rise in taxes and government expenditure.

Space education: Deriving benefits from industrial consortia

As the number of spacefaring nations of the world increases, so does the difficulty of competing in a global economy. The development of high technology products and services for space programs, and the economic exploitation of these technologies for national economic growth, requires professionals versed in both technical and commercial aspects of space. Meeting this requirement academically presents two challenges. On the technical side, enrollment in science and engineering is decreasing in some of the spacefaring nations. From the commerce perspective, very few colleges and universities offer specific courses in space business

Solid Lipid Nanoparticles: A Potential Approach for Dermal Drug Delivery

Solid lipid nanoparticles (SLNs) have attracted increasing attention during recent years. Due to their unique size dependent properties, lipid nanoparticles offer possibilities to develop new therapeutics. The ability to incorporate drugs into nanoparticles offers a new prototype in drug delivery thus realizing the dual goal of both controlled release and site-specific drug delivery. Drug delivery to the skin is widely used for local and systemic delivery and has potential to be improved by application of nanoparticulate formulations. If investigated appropriately, solid lipid nanoparticles may open new opportunities in therapy of complex diseases which is difficult to treat

Hydrophilic Matrices for Oral Control Drug Delivery

Oral controlled drug delivery has gathered tremendous attention over the years due to its many advantages over conventional dosage forms. Polymer-based matrices have become an integral part of the pharmaceutical industry. Hydrophilic matrices are capable of controlling the release of drug over an extended period of time. Hydrophilic polymers, especially the hydrophilic derivatives of cellulose ethers, are frequently used for these applications. Therefore, the objective of this review is to discuss the scientific and physicochemical aspects of these polymeric systems that can affect the drug release from such formulation

Assuring Access to Care Under Health Reform: The Key Role of Workforce Policy

Examines policy and practical options for addressing the projected shortage of primary care physicians to ensure access to health care under expanded insurance coverage, including reorganizing practices to make productive use of nurses and other staff

Transient and stationary behavior of the Olami-Feder-Christensen earthquake model

Using long-term computer simulations and mean-field like arguments, we investigate the transient time and the properties of the stationary state of the Olami-Feder-Christensen earthquake model as function of the coupling parameter $\alpha$ and the system size $N$. The most important findings are that the transient time diverges nonanalytically when $\alpha$ approaches zero, and that the avalanche-size distribution will not approach a power law with increasing system size.Comment: 10 pages, 8 figure

Handbook for Implementing a Comprehensive Work-Based Learning Program According to the Fair Labor Standards Act

This Handbook for Implementing a Comprehensive Work-Based Learning Program According to the Fair Labor Standards Act provides guidance to schools operating WBL programs and encourages the adoption of WBL programs by schools not presently using this approach. By following the information and examples in this handbook, schools can proceed with confidence to operate effective WBL programs consistent with the FLSA

On Hamilton Decompositions of Line Graphs of Non-Hamiltonian Graphs and Graphs without Separating Transitions

In contrast with Kotzig's result that the line graph of a $3$-regular graph $X$ is Hamilton decomposable if and only if $X$ is Hamiltonian, we show that for each integer $k\geq 4$ there exists a simple non-Hamiltonian $k$-regular graph whose line graph has a Hamilton decomposition. We also answer a question of Jackson by showing that for each integer $k\geq 3$ there exists a simple connected $k$-regular graph with no separating transitions whose line graph has no Hamilton decomposition
