Quality Risk Management: A Role-Based Competency Model For The Biopharmaceutical Sector, Ghada Haddad

Journal of Applied Pharmaceutical Regulatory Science

In 2005, the International Conference on Harmonisation’s (ICH’s) ‘’Q9’’, aimed at providing the biopharmaceutical sector with guidance towards a science and risk-based approach to quality management was published. The concepts outlined in ICH Q9 focused on the fact that evaluation of the risk to quality should be based on scientific knowledge and ultimately link to the protection of the patient.

The purpose of ICH Q9 is to offer a systematic approach to quality risk management (QRM). It serves as a foundation or resource document that is independent of yet supports other ICH Quality documents and complements existing quality practices, requirements, …

Taking A Stand For Quality: Demonstrating Pqs Effectiveness By Operationalizing Qrm And Km, Kevin O'Donnell, Martin J. Lipa, Anne Greene (Editor)

Journal of Applied Pharmaceutical Regulatory Science

While the authors have published widely on the need to unite the twin enablers of ICH Q10 [1], quality risk management (QRM) and knowledge management (KM), how to integrate QRM and KM in practice has proven to be quite challenging. QRM and KM are wide-ranging activities that impact many elements of pharmaceutical manufacturing and regulation. Pharmaceutical manufacturers and their regulators work to apply risk-based approaches to their work and strive to use knowledge in a smart and efficient way, but so far, in the experience of the authors, it has proven difficult to get these things right.

One way to …

Synthetic Data And Gdpr Compliance: How Artificial Intelligence Might Resolve The Privacy-Utility Tradeoff, Michael Cairo

Journal of Technology Law & Policy

Data is in many ways the lifeblood of the digital economy. High-quality data oftentimes requires significant detail which may be at odds with the privacy concerns of the human subjects from whom data is extracted. The tension between the usefulness of a dataset and the data subject’s privacy has been referred to as the “privacy-utility tradeoff.” A novel application of artificial intelligence has potentially made it possible to resolve this tradeoff through the creation of “synthetic data,” anonymized data generated through general adversarial neural networks from authentic raw data. Unlike pseudonymized data, synthetic data retain properties that are statistically equivalent …

Moving The United States Into The 21st Century For Children's Online Privacy Rights, Zackary A. Blanton

Journal of Technology Law & Policy

It has been more than twenty-five years since the Children’s Online Privacy Protection Act (COPPA) was first implemented in the United States. Since its enactment—well over a decade ago—there has been only one instance in which Congress successfully passed noteworthy modifications to the Act. While there has been a recent increase in proposed amendments to the Act better to protect children in our current reality of everchanging technology, little has been done to initiate the much-needed change. The increased focus on children’s online rights has been sparked primarily by changes made in the United Kingdom. At the forefront of the …

Development Of A Drive-Rod Unified Variable Pitch Control Mechanism For Small-Scale Horizontal Wind Turbines, Ayman I. Bakry, Mohamed Elfouly, Omar Mehrez

Journal of Engineering Research

Typically, small-scale wind turbines use either a breaking equipment or stall control methods once the wind speed exceeds its rated value. This is to limit the power extracted from the wind turbines which largely depends on the blades' shape and pitch angle. Most of small-scale wind turbines are of fixed pitch angle to avoid complexity and cost. In this work, a novel drive-rod unified variable pitch drive mechanism is proposed for blades pitch control for small-scale horizontal wind turbines. The mechanism is powered by a DC motor coupled with a lead screw which in turn is connected to the pitch …
