Robot Autonomy for Surgery

Autonomous surgery involves having surgical tasks performed by a robot operating under its own will, with partial or no human involvement. There are several important advantages of automation in surgery, which include increasing precision of care due to sub-millimeter robot control, real-time utilization of biosignals for interventional care, improvements to surgical efficiency and execution, and computer-aided guidance under various medical imaging and sensing modalities. While these methods may displace some tasks of surgical teams and individual surgeons, they also present new capabilities in interventions that are too difficult or go beyond the skills of a human. In this chapter, we provide an overview of robot autonomy in commercial use and in research, and present some of the challenges faced in developing autonomous surgical robots

Why forums? An empirical analysis into the facilitating factors of carding forums

Over the last decade, the nature of cybercrime has transformed from naive vandalism to profit-driven, leading to the emergence of a global underground economy. A noticeable trend which has surfaced in this economy is the repeated use of forums to operate online stolen data markets. Using interaction data from three prominent carding forums: Shadowcrew, Cardersmarket and Darkmarket, this study sets out to understand why forums are repeatedly chosen to operate online stolen data markets despite numerous successful infiltrations by law enforcement in the past. Drawing on theories from criminology, social psychology, economics and network science, this study has identified four fundamental socio-economic mechanisms offered by carding forums: (1) formal control and coordination; (2) social networking; (3) identity uncertainty mitigation; (4) quality uncertainty mitigation. Together, they give rise to a sophisticated underground market regulatory system that facilitates underground trading over the Internet and thus drives the expansion of the underground economy

By Name United, By Sex Divided: A Brief Analysis of the Current Crisis Facing the Anglican Communion

The current controversies in relation to homosexuality - which emanated from the western quarters but quickly engulfed the entire Anglican Communion - highlight two significant issues. In our view, the first issue, regarding the 'religious citizenship' of lesbian and gay Christians, is generally a western concern. The second issue pertaining to the prospect of the disintegration of the Anglican Communion, however, needs to be examined within a global context. On the first issue, we argue that, since the contemporary western religious landscape (and society in general) prioritizes the authority of the self rather than that of religious institution/tradition, the traditional religious discourse that marginalizes lesbian and gay Christians is undermined by an increasingly sophisticated reverse discourse. This reverse discourse, equipped with lesbian and gay affirming theology and documentation of lived experiences, also converges with contemporary cultural (secular) discourse of human rights and personal liberty, which values social diversity, including sexual difference. We believe that the social and political currency of the reverse discourse will proliferate, thus eclipsing the traditional discourse that appears increasingly out of step with contemporary western socio-cultural reality. On the second issue, we welcome the heightened significance and relevance of (local) culture and Christianity in the debate. We argue that the decentralization (i.e. de-westernization) of the Anglican Communion should be welcomed, for there are various versions of Christianity, the conception and practice of which are closely informed by local cultures. Thus, to force the production of a unified Anglican response to moral or social issues that are differently defined across cultures may prove counter-productive.Anglican; Belief; Christian; Church; Gay; Homosexuality; Identity; Lesbian; Priest

A Structural Investigation into the Price and Wage Dynamics in Hong Kong

This paper estimates the degree of wage and price flexibility of the Hong Kong economy with the use of a stylised dynamic stochastic general equilibrium (DSGE) model developed for the Hong Kong economy. It also studies the factors contributing to deflation in Hong Kong following the Asian financial crisis (i.e. during the period from 1998 to 2003) and finds that declining import prices were the main culprit. Consistent with earlier studies on the subject and anecdotal evidence, wages and prices in Hong Kong are found to be (relatively) flexible.DSGE, Bayesian Estimation, Nominal Rigidities
