Deep understanding of mathematical equivalence is critical for later mathematical understandings. However, research studies and national test results have repeatedly demonstrated that many students fail to develop adequate understanding of equivalence. Recent work from McNeil and colleagues proposes that this failure is partly due to the format of traditional instruction and practice with highl...

There is substantial in-vitro data indicating that curcumin has antioxidant, anti-inflammatory, and anti-amyloid activity. In addition, studies in animal models of Alzheimer's disease (AD) indicate a direct effect of curcumin in decreasing the amyloid pathology of AD. As the widespread use of curcumin as a food additive and relatively small short-term studies in humans suggest safety, curcumin ...

Introduction: The paper describes an interim model for understanding the influences on information use in relation to plagiarism, with a focus on secondary school students. Available literature mostly focuses on the tertiary level and on quantifying the extent of plagiarism, with limited availability of theory or empirical research focussing on information use, learning and plagiarism. Theoreti...

A steady-state mouse model was developed to determine arsenic (As) relative bioavailability (RBA) in rice to refine As exposure in humans. Fifty-five rice samples from 15 provinces of China were analyzed for total As, with 11 cooked for As speciation and bioavailability assessment. Arsenic concentrations were 38-335 μg kg-1, averaging 133 μg kg-1, with AsIII being dominant (36-79%), followed by...

Many Internet services require high availability. Server pooling provides a high availability solution using redundant servers. If one server fails, the service is continued by another one. A challenge for server pooling is efficient state sharing: The new server requires the old one’s state to continue service. This paper proposes a simple, efficient and scalable solution, usable for a large s...

0 Abstract The increasing popularity of cloud storage services has led many companies to migrate their data into clouds for high availability whilst saving infrastructure constructions. Within the last few years, the architectures of most major cloud storage providers have evolved from single data center to multiple data centers, across different geo-locations. This architecture help improve th...

Automotive Services stellen ein wichtiges Differenzierungsmerkmal der Automobilhersteller dar und gewinnen zunehmend an Bedeutung. Um ihre Kunden nicht aufgrund mangelnder Dienstqualität zu verärgern, wird nach einer Möglichkeit gesucht, die zu erwartende Dienstgüte bereits im Voraus bestimmen zu können. In diesem Beitrag beschreiben wir einen Ansatz zur qualitativen Bewertung von Automotive Se...

In this paper, we look at what is required to produce programs that are dependable. Dependability requires more than just high availability. Rather, a program needs to be ―right‖ as well, solving the problem for which it was designed. This requires a program development infrastructure that can, by means of appropriate abstractions, permit the programmer to focus on his problem, and not be distr...

This study develops and estimates a dynamic model of consumer choice behavior in markets for seasonal goods where products are sold over a finite season and availability is limited. In these markets, retailers often use dynamic markdown policies in which an initial retail price is announced at the beginning of the season and the price is subsequently marked down as the season progresses. Strate...
