Enrichment of dissolved silica in the deep equatorial Pacific during the Eocene-Oligocene

Silicon isotope ratios (expressed as δ30Si) in marine microfossils can provide insights into silica cycling over geologic time. Here we used δ30Si of sponge spicules and radiolarian tests from the Paleogene Equatorial Transect (Ocean Drilling Program Leg 199) spanning the Eocene and Oligocene (~50-23 Ma) to reconstruct dissolved silica (DSi) concentrations in deep waters and to examine upper ocean

Holocene vegetation and hydroclimatic dynamics in SE Lithuania - Implications from a multi-proxy study of the Čepkeliai bog

Due to the scarcity of reliable palaeoecological and climatic proxy records from the Eastern Baltic covering the Holocene, there has been increased interest for multi-proxy studies in the region to detect local to regional environmental changes. The Čepkeliai wetland complex, SE Lithuania, provides an uninterrupted Holocene sediment sequence, which is used here to reconstruct palaeoenvironmental h

The Paradox of Progress : the Emergence of Wage Discrimination in US Manufacturing

This article tests for wage discrimination in US manufacturing during the nineteenth century and in 2002 by estimating the female-to-male productivity ratio and comparing it to the wage ratio. This method will not identify all forms of discrimination, but will determine whether women were paid wages commensurate with their productivity. There was no significant difference between the wage ratio an

A 128 kb 7T SRAM Using a Single-Cycle Boosting Mechanism in 28 nm FD–SOI

A 128kb ultra-low voltage SRAM, based on a leakage optimized single-WELL 7T bitcell in 28 nm FD–SOI technology is presented. An ideal power management scenario in a single supply system is achieved by permanently keeping the storage elements in the vicinity of the retention voltage. Performance and reliability is regained by boosting the voltage on critical nodes. The cost of voltage boost generat

Creating Better Innovation Measurement Practices

For most companies, innovation is a top managerial priority. Business executives look at successful innovators such as Apple and Google with envy, wishing their companies could be half as innovative. To boost and benchmark innovation, managers often use quantitative performance indicators, but they struggle with identifying the right metric. Yet, our research suggests that the key managerial chall

A unified ensemble of concatenated convolutional codes

We introduce a unified ensemble for turbo-like codes (TCs) that contains the four main classes of TCs: parallel con- catenated codes, serially concatenated codes, hybrid concatenated codes, and braided convolutional codes. We show that for each of the original classes of TCs, it is possible to find an equivalent ensemble by proper selection of the design parameters in the unified ensemble. We also

Quality enhancement through the introduction of SoTL : From tips and tricks to a scholarly approach

The aim of courses conducted by centers for educational development is to enhance and sustain quality in teaching and learning in higher education. Research suggests that taking a scholarly approach to teaching and learning results in higher quality teaching, which, in turn, promotes student learning (Trigwell & Shale, 2004). Moreover, a scholarly approach to teaching and learning helps sustai

Constructive friction? Exploring patterns between Educational Research and The Scholarship of Teaching and Learning

While educational research (EdR) and the Scholarship of Teaching and Learning (SoTL) are overlapping fields there remains considerable friction between the two. Shulman, (2011, p. 5), recounts a situation when an EdR colleague accused him “of contributing to the bastardization of the field by encouraging faculty members who were never trained to conduct educational or social science research to en
