The purpose of this paper is to examine the currently known techniques to tackle money laundering in Bitcoin mixers, and examine what gaps exist that would allow a criminal to get away with laundering Bitcoin obtained through illicit activities.

This paper first establishes the relevant properties of Bitcoin, how transactions occur over the Bitcoin network and then introduces the Bitcoin transaction graph as an important data structure for any analysis of Bitcoin transactions. Next, the paper outlines how Bitcoin mixing works, along with the relevant properties of mixers that would be relevant for money laundering. The paper then assesses the known methods for identifying mixed transactions within the Bitcoin network, followed by an assessment on identifying money laundering activities on known mixed transactions.

This paper argues that there remains a gap for criminals to launder money through Bitcoin mixing services as known methods would unlikely be able to trace a tainted transaction that goes through a decentralized mixer that uses off-chain communication techniques to coordinate the mixing and charges randomized mixing fees.

The study of known methods is restricted to literature published in the public domain. There are private organizations that are tackling similar problems, but their methods are not published and therefore cannot be included in this paper.

To best of the author’s knowledge, this is the first paper that performs a contemporaneous review on anti-money laundering in the context of Bitcoin mixing. This paper could assist regulators and policymakers in their understanding of Bitcoin mixers and provide guidance on where they should focus their resources to address the money laundering problem of Bitcoin mixing.

The task of changing the organizational climate of a school is only one tiny example of the fundamental issue of permanence and change. This example can only be understood in the light of a broad social and intellectual matrix. Two prime questions are: Under what conditions can the organizational climate be changed? If it can be changed, what approach is most appropriate? There is a great deal that is not known about organizational climate. Research is needed into the development of norms, the control of variables in experimental situations, the effects of size and “human density” and the influence of bureaucracy. Though we may be anxious to change organizational climate, one thing is clear—social change takes place slowly. To force its growth “out of phase” is to invite unanticipated social consequences. If the nature of social change is to be understood the planners, scientists, technologists need to maintain dialogue with each other. We must create in our society an “open” organizational climate that encourages the human dialogue.

The purpose of this paper is to review the legacy of sociologist Irving Kenneth Zola in bringing the body into social science research and making visible and dismantling social structured barriers to hearing and speaking and living as fully human.

It begins with an examination of Zola’s experience of “being sexy” in his book, Missing Pieces (1982). It considers what a visual sociological focus on “being sexy” can contribute to understanding structured barriers to living as fully human after the emergence of this field in the 1990s and 2000s.

It provides two examples of the use of video cameras in understanding the daily experiences of adults using wheelchairs and children with asthma that continue the embodied work begun by Zola.

Embodied sociological research can be a strategy for social and political change.

This paper explores the links between economic and social structures and ethical norms for economic life. As such, the essay is a contribution to the more general philosophical discussions on the relation between fact and value in the social sciences. I begin with a brief discussion of ethics which highlights the social character of ethical “value” and draws upon the work of the Canadian philosopher, Bernard Lonergan, to introduce a novel way of understanding social structures. The analyses show how economic structures can be understood as cooperative meaning schemes, how such schemes are embedded within a wider ecology of social meaning schemes, and how the dynimic relations among such schemes reveal ethical goals and make ethical demands upon participants who depend upon them for their living. I illustrate these linkages in a discussion of three examples drawn from economic life: a consumer purchase transaction, an ancient trade scheme drawn from the work of Karl Polanyi, and a rather novel approach to economic development proposed by Jane Jacobs.

Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

The critical dimension and the one that can unify knowledge through systemic interrelationships, is unification of the purely a priori with the purely a posteriori parts of total reality into a congruous whole. This is a circular cause and effect interrelationship between premises. The emerging kind of world view may also be substantively called the epistemic‐ontic circular causation and continuity model of unified reality. The essence of this order is to ground philosophy of science in both the natural and social sciences, in a perpetually interactive and integrative mould of deriving, evolving and enhancing or revising change. Knowledge is then defined as the output of every such interaction. Interaction arises first from purely epistemological roots to form ontological reality. This is the passage from the a priori to the a posteriori realms in the traditions of Kant and Heidegger. Conversely, the passage from the a posteriori to a priori reality is the approach to knowledge in the natural sciences proferred by Cartesian meditations, David Hume, A.N. Whitehead and Bertrand Russell, as examples. Yet the continuity and renewal of knowledge by interaction and integration of these two premises are not rooted in the philosophy of western science. Husserl tried for it through his critique of western civilization and philosophical methods in the Crisis of Western Civilization. The unified field theory of Relativity‐Quantum physics is being tried for. A theory of everything has been imagined. Yet after all is done, scientific research program remains in a limbo. Unification of knowledge appears to be methodologically impossible in occidental philosophy of science.

Strategic investment theory establishes a framework for discussing the benefits of acquisitions. However, these theories do not provide automatic answers to investment questions.
