This handbook is an approachable reference for all levels of educational leadership. The topics are presented with a clarity that makes the mathematics accessible, even if the reader has not had prior training in research methods or statistics.

I was awarded sabbatical leave for Fall 2009. My sabbatical proposal was titled “How Web 2.0 Technologies Are Transforming Writing in Nonprofit Organizations.” My plan, as laid out in my sabbatical proposal, involved tracking and analyzing the online presence of 3-5 nonprofit organizations, and reporting on the ways the nature of their organizational writing had changed, directly and indirectly, as a result of the use of web 2.0 technologies, including blogs, wikis, and social networking sites such as Facebook and Twitter.

This project involved gathering, analyzing, and preparing for publication the new empirical evidence on the working of capital markets in several economies of East and Central Europe, additionally providing material to enrich the curriculum in economics and finance. It also provided material for a conference presentation.

"Beautiful, feisty Dara, rising from nomad to princess, experiences joy, spiritual and marital conflict, and unspeakable trials, without surrendering her love for Job and for her best friend Adah"--p. 4 of Cover.

The chapter on the information ethics of Oxford scholar, Luciano Floridi, was completed and is scheduled for publication in Floridi's anthology. The keynote address, Philosophy and the Information Revolution, presented at the Computer Ethics: Philosophical Enquiry 2009 conference in Corfu, Greece, is also scheduled for publication in the journal Ethics and Information Technology. The ideas from both articles have been included in the curriculum for the Computer Ethics class at SCSU.

Although Spanish chroniclers referred frequently to coerced migration in the Inca Empire, these migrations have been difficult to document archaeologically. One approach to migration studies, strontium isotope (87Sr/86Sr) analysis, has emerged as an effective technique. Until now, however, this method has not been applied to the Inca heartland region of Cuzco, Peru. In this study, we use strontium isotope analysis to examine patterns of prehistoric migration in the Cuzco Valley. Human dental enamel samples from the Cuzco Valley site of Chokepukio are analyzed and compared to the local 87Sr/86Sr signature established through faunal specimens. Though tentative due to a small sample size, the isotope results do not provide evidence for migration at this site from the time periods preceding the rise of the Inca Empire (200 B.C. to A.D. 1400). In contrast, there is substantial evidence for migration during the time of Inca imperialism (A.D. 1400-1532). Among these migrants, variation in 87Sr/86Sr values suggests that individuals emigrated from geologically diverse locations, while sex differences in the migrant group include a higher percentage of females and a greater diversity in female 87Sr/86Sr values. These data, along with ethnohistoric evidence, reveal how Inca labor policies reconfigured the composition of populations in the imperial heartland.

Mayflies are members of a small, but diverse order of aquatic insects that dates back some 290. My. Mayflies are widely distributed on all continents and most large islands. Currently, the order contains about 3100. species distributed among 42 extant families. Adults are fully terrestrial and short lived, but the aquatic nymphs can live for more than a year and are important components of nutrient and energy pathways in a wide range of aquatic habitats. Higher classification and phylogeny of the mayflies are still in a state of flux, but evidence is accumulating providing stronger support for some groups. Alpha-level taxonomy still remains a problem and much work remains to be done in some genera and in some parts of the world. Extensive morphological studies have provided a solid base of knowledge, but similarly intense physiological, histological, and immunological studies are needed. Much work has been done on the ecology of genera and some species. Much finer scale ecological studies are needed to better understand the importance of small-scale ecological interactions among instars of the same and different species. Globally, there are many surveys in progress to document and map the occurrence and distribution of species. This work is critical to developing conservation strategies for mayflies and other vulnerable aquatic species. © 2009 Elsevier Inc. All rights reserved.

Magnitude differences obtained from speckle imaging are used in combination with other data in the literature to place the components of binary star systems on the H-R diagram. Isochrones are compared with the positions obtained, and a best-fit isochrone is determined for each system, yielding both masses of the components as well as an age range consistent with the system parameters. Seventeen systems are studied, 12 of which were observed with the 0.6 m Lowell-Tololo Telescope at Cerro Tololo Inter-American Observatory and six of which were observed with the WIYN 3.5 m Telescope (The WIYN Observatory is a joint facility of the University of Wisconsin-Madison, Indiana University, Yale University, and the National Optical Astronomy Observatories) at Kitt Peak. One system was observed from both sites. In comparing photometric masses to mass information from orbit determinations, we find that the photometric masses agree very well with the dynamical masses, and are generally more precise. For three systems, no dynamical masses exist at present, and therefore the photometrically determined values are the first mass estimates derived for these components. © 2009 The American Astronomical Society.

Assisted Reproductive Technology (ART) is a modern technological tool that provides otherwise infertile individuals and couples an opportunity to conceive. As a multimillion dollar business, ART faces challenges common to other highly profitable enterprises, such as how and when to measure success. This poses ethical challenges as well, though these are unlike the ethical challenges faced by businesses which trade in consumer goods. ART makes babies. Individuals and couples seeking ART may be both vulnerable and fragile, thus ART providers must gently balance smart business practices with ethical care delivery. Applying Laura Nash's integrated approach to business ethics may offer ART providers a suitable model that combines ethically sound care with economically sound business practice. Key to Nash's approach are value creation, economic and social benefit, and relationship building. Not a short-term approach to quick business decisions, Nash's approach requires a long-term commitment as a way of doing business. © Common Ground, Deborah Flynn, All Rights Reserved.

Contractedness of m-primary integrally closed ideals played a central role in the development of Zariski's theory of integrally closed ideals in two-dimensional regular local rings (R, m). In such rings, the contracted m-primary ideals are known to be characterized by the property that I: m = I: x for some x ∈ m\m2. We call the ideals with this property full ideals and compare this class of ideals with the classes of m-full ideals, basically full ideals, and contracted ideals in higher dimensional regular local rings. The m-full ideals are easily seen to be full. In this article, we find a sufficient condition for a full ideal to be m-full. We also show the equivalence of the properties full, m-full, contracted, integrally closed, and normal, for the class of parameter ideals. We then find a sufficient condition for a basically full parameter ideal to be full. © Taylor & Francis Group, LLC.
