Fraud cycles

Fraud is an ancient crime and one that annually causes hundreds of billions of dollars in losses. We examine the behavioral patterns over time of different types of frauds, which illustrate cyclical frequencies. We develop an evolutionary theory that suggests cyclic behavior in frauds should be common.fraud, cycle, steady state

Advancing Well-Being by Transcending the Barriers of Whiteness

PolicyLink, in partnership with Well Being Trust, developed Advancing Well-Being by Transcending the Barriers of Whiteness to identify "centering whiteness" as a social and institutional framework that prevents meaningful movement toward racial equity, describe specific social and economic inequities that have been exacerbated by this framework, and make clear new narratives that will be necessary for systemic and policy change. This paper, along with the companion Community Dialogue Guide, serve as the starting point for critical dialogues that deepen and build shared understanding across communities

Operating Regimes and Automated Control of Holmium and Thulium Non-linear Polarisation Rotation Mode-locked Fibre Optic Lasers

Mode-locked fibre lasers have applications in research, defence, biological science, manufacturing and spectroscopy. The aim of this research was to investigate auto- matic control of a passive mode-locking technique known as non-linear polarisation rotation (NLPR) that exploits polarisation differences across a pulse’s profile that manifest due to different intensities. This research seeks to focus on how NLPR laser sources can be made stable, especially at longer wavelengths (such as 2 µm). Three different fibre lasers were developed to investigate different aspects of NLPR. An erbium mode-locked source was used to explore measurement techniques and competing operating regimes. The operating regimes were controlled using a manual polarisation controller. Characterisation revealed that the source produced 570 fs pulses with a central wavelength of 1567 nm, repetition rate of 17 MHz and pulse energy of 3 nJ. A thulium NLPR source was developed to further explore possible automation metrics and characterise a range of additional undesired operating regimes. Automation metrics tested to determine if the laser was continuously mode-locked included discontinuities in Stokes parameters, two-photon absorption signals and amplitude modulation across the radio-frequency spectrum of the laser. Characterisation revealed that the source produced 1.15 ps pulses with a central wavelength of 1990 nm, repetition rate of 21 MHz and pulse energy of 5 nJ. Lastly, a holmium NLPR source with electronic control of the intra-cavity polarisation state was built. To the best of our knowledge, this is the first diode-pumped NLPR mode-locked holmium source in the 2µm waveband. An automation mechanism was devised and implemented. Characterisation revealed that the source produced 770 fs pulses with a central wavelength of 2061 nm, a repetition rate of 17 MHz and pulse energy of 0.41 nJ.Thesis (M.Phil) -- University of Adelaide, School of Physical Sciences : Physics, 202

Collusive Bidding in the Market for Corporate Control

Part I of this article examines the historical evolution of antitrust laws, specifically as they have been applied to the market for corporate control. Part II examines the current judicial opinions advanced which reject the application of antitrust laws to the market for corporate control, including the supposed nonapplicability of antitrust laws to the sale of stock and the implied revocation of the antitrust laws by virtue of the enaction of the Williams Act. Part III addresses the inability of the Securities and Exchange Commission to regulate the market for corporate control via the Williams Act in that there is no inherent conflict between the Commission\u27s disclosure requirements and the policy of antitrust laws. Part IV analyzes the quantitative economic effects of the diminution of competition in the market for corporate control and examine its aggregate effect on shareholders

Moving from Intention to Impact: Funding Racial Equity to Win

This joint PolicyLink-Bridgespan analysis says funders are a key part of the racial equity ecosystem: to benefit the entire nation they should both be transparent in reporting where grants go and fund what movement leaders say is needed to achieve enduring change
