Multifunctional Software-Defined Radar Sensor and Data Communication System

Abstract: Orthogonal frequency-division multiplexing (OFDM) signal coding and system architecture were implemented to achieve radar and data communication functionalities. The resultant system is a software-defined unit, which can be used for range measurements, radar imaging, and data communications. Range reconstructions were performed for ranges up to 4 m using trihedral corner reflectors with approximately 203 m of radar cross section at the carrier frequency; range resolution of approximately 0.3 m was demonstrated. Synthetic aperture radar (SAR) image of a single corner reflector was obtained; SAR signal processing specific to OFDM signals is presented. Data communication tests were performed in radar setup, where the signal was reflected by the same target and decoded as communication data; bit error rate of was achieved at 57 Mb/s. The system shows good promise as a multifunctional software-defined sensor which can be used in radar sensor networks.

A quasi-experimental assessment of the effect of computerizing noncognitive paper-and-pencil measurements: A test of measurement equivalence.

Abstract: Previous studies have provided evidence to question the equivalence of data gathered by different administration modes and to suggest that noncognitive instruments validated for paper-and-pencil administration may not be valid for computerized administration. In this study, a series of analyses of the variance-covariance matrices tested the measurement equivalence of data collected from paper-and-pencil and computerized formats. Four work-related noncognitive psychological measures were tested in this study. There was no evidence that administration mode had an effect on measurement equivalence.

Critical spirituality: enhancing transformative leadership through critical theory and African American prophetic spirituality

Abstract: In this essay I suggest that ‘critical spirituality’, an amalgamation of critical theory and African American prophetic spirituality can enhance the discourse of transformative educational leadership. I argue that this new theoretical interpretation can function to not only deconstruct asymmetrical relations of power that dominate the educational system but can also be instrumental in prescribing acts of reflective resistance purposed to bring about a radical reconstruction of schools.

Electronic word of mouth: The effects of incentives on e‐referrals by senders and receivers

Abstract: Purpose – The purpose of this work is to test several incentive strategies for attaining new customers via electronic referrals, or e‐referrals. The paper aims to examine: the roles of both the magnitude of the incentive offered to the sender and the magnitude of the incentive offered to the receiver; and the effect of equity versus inequity of financial incentives for the two parties.Design/methodology/approach – The study consisted of a large‐scale field experiment conducted with 45,000 members of an online mall. The participants were divided into eight conditions in an incomplete two‐factor 4×4 between‐subjects design, where not every combination of incentive magnitudes was utilized and the magnitude of the incentive offered the receiver and sender varied in size such that sometimes rewards were equal, sometimes receivers of the e‐referral had larger rewards, and sometimes senders of the e‐referral s received more. Dependent measures included the number of e‐referrals sent, the number of those e‐referr...

Biomaterials for the Delivery of Growth Factors and Other Therapeutic Agents in Tissue Engineering Approaches to Bone Regeneration.

Abstract: Bone fracture followed by delayed or non-union typically requires bone graft intervention. Autologous bone grafts remain the clinical "gold standard". Recently, synthetic bone grafts such as Medtronic's Infuse Bone Graft have opened the possibility to pharmacological and tissue engineering strategies to bone repair following fracture. This clinically-available strategy uses an absorbable collagen sponge as a carrier material for recombinant human bone morphogenetic protein 2 (rhBMP-2) and a similar strategy has been employed by Stryker with BMP-7, also known as osteogenic protein-1 (OP-1). A key advantage to this approach is its "off-the-shelf" nature, but there are clear drawbacks to these products such as edema, inflammation, and ectopic bone growth. While there are clinical challenges associated with a lack of controlled release of rhBMP-2 and OP-1, these are among the first clinical examples to wed understanding of biological principles with biochemical production of proteins and pharmacological principles to promote tissue regeneration (known as regenerative pharmacology). After considering the clinical challenges with such synthetic bone grafts, this review considers the various biomaterial carriers under investigation to promote bone regeneration. This is followed by a survey of the literature where various pharmacological approaches and molecular targets are considered as future strategies to promote more rapid and mature bone regeneration. From the review, it should be clear that pharmacological understanding is a key aspect to developing these strategies.
