Study of management decision making by ward sisters in a hospital and the effects on decision making after the implementation of a decision support sytem

This thesis considers management decision making at the ward level in hospitals especially by ward sisters, and the effectiveness of the intervention of a decision support system. Nursing practice theories were related to organisation and management theories in order to conceptualise a decision making framework for nurse manpower planning and deployment at the ward level. Decision and systems theories were explored to understand the concepts of decision making and the realities of power in an organisation. In essence, the hypothesis was concerned with changes in patterns of decision making that could occur with the intervention of a decision support system and that the degree of change would be governed by a set of `difficulty' factors within wards in a hospital. During the course of the study, a classification of ward management decision making was created, together with the development and validation of measuring instruments to test the research hypothesis. The decision support system used was rigorously evaluated to test whether benefits did accrue from its implementation. Quantitative results from sample wards together with qualitative information collected, were used to test this hypothesis and the outcomes postulated were supported by these findings. The main conclusion from this research is that a more rational approach to management decision making is feasible, using information from a decision support system. However, wards and ward sisters that need the most assistance, where the `difficulty' factors in the organisation are highest, benefit the least from this type of system. Organisational reviews are needed on these identified wards, involving managers and doctors, to reduce the levels of un-coordinated activities and disruption.

Watermark-only security attack on DM-QIM watermarking:vulnerability to guided key guessing

This paper addresses the security of a specific class of common watermarking methods based on Dither modulation-quantisation index modulation (DM-QIM) and focusing on watermark-only attacks (WOA). The vulnerabilities of and probable attacks on lattice structure based watermark embedding methods have been presented in the literature. DM-QIM is one of the best known lattice structure based watermarking techniques. In this paper, the authors discuss a watermark-only attack scenario (the attacker has access to a single watermarked content only). In the literature it is an assumption that DM-QIM methods are secure to WOA. However, the authors show that the DM-QIM based embedding method is vulnerable against a guided key guessing attack by exploiting subtle statistical regularities in the feature space embeddings for time series and images. Using a distribution-free algorithm, this paper presents an analysis of the attack and numerical results for multiple examples of image and time series data.

Queer sex work

Sex work is a subject of significant contestation across academic disciplines, as well as within legal, medical, moral, feminist, political and socio-cultural discourses. A large body of research exists, but much of this focuses on the sale of sex by women to men and ignores other performances, practices, meanings and embodiments in the contemporary sex industry. A queer agenda is important in order to challenge hetero-centric gender norms and to develop new insights into how gender, sex, power, crime, work, migration, space/place, health and intimacy are understood in the context of commercial sexual encounters. Queer Sex Work explores what it might mean to 'be', 'do' and 'think' queer(ly) in the study and practice of commercial sex. It brings together a multiplicity of empirical case studies - including erotic dance venues, online sex working, pornography, grey sexual economies, and BSDM - and offers a variety of perspectives from academic scholars, policy practitioners, activists and sex workers themselves. In so doing, the book advances a queer politics of sex work that aims to disrupt heteronormative logics whilst also making space for different voices in academic and political debates about commercial sex. This unique and multidisciplinary volume will be indispensable for scholars and students of the global sex trade and of gender, sexuality, feminism and queer theory more broadly, as well as policymakers, activists and practitioners interested in the politics and practice of sex work in local, national and international contexts.

Workplace crime and the informal economy in Ukraine: Employee and employer perspectives

Purpose – The purpose of this paper is to explore the criminal workplace activities of both employers and employees in Ukrainian enterprises. It challenges traditional definitions of corruption and suggests that the practices that can be observed fit into the category of organised crime because of the country's economic framework. The paper also explores how the practices are partially a legacy of Soviet economic processes. Design/methodology/approach – A total of 700 household surveys were completed in three cities, Kyiv (where 450 surveys were completed), Uzhgorod (150) and Kharkiv (100). To complement these, approximately 25 in-depth interviews were undertaken with workers in each region. Furthermore, ethnographic observations and “kitchen table” interviews also played an important role in the research. Although the research was oriented towards those working in informal economies, business owners (both formal and informal) were also interviewed. Findings – As well as revealing the endemic nature of corruption in Ukrainian workplaces and the high levels of informal activity undertaken by workers, the research found that many people wish for their workplace to become more regulated. Research limitations/implications – Further interviews could have been carried out with state officials and in more locations. The implications are multiple but mainly they demonstrate the difficulty that those charged with economic reform in Ukraine must face. Originality/value – It is one of the first studies to explore these issues in Ukraine using a variety of research methods.

EU governance of the internet:analyzing Europol’s role in the development of a EU cyber crime and cyber security policies

In recent years, the European Union has come to view cyber security, and in particular, cyber crime as one of the most relevant challenges to the completion of its Area of Freedom, Security and Justice. Given European societies’ increased reliance on borderless and decentralized information technologies, this sector of activity has been identified as an easy target for actors such as organised criminals, hacktivists or terrorist networks. Such analysis has been accompanied by EU calls to step up the fight against unlawful online activities, namely through increased cooperation among law enforcement authorities (both national and extra- communitarian), the approximation of legislations, and public- private partnerships. Although EU initiatives in this field have, so far, been characterized by a lack of interconnection and an integrated strategy, there has been, since the mid- 2000s, an attempt to develop a more cohesive and coordinated policy. An important part of this policy is connected to the activities of Europol, which have come to assume a central role in the coordination of intelligence gathering and analysis of cyber crime. The European Cybercrime Center (EC3), which will become operational within Europol in January 2013, is regarded, in particular, as a focal point of the EU’s fight against this phenomenon. Bearing this background in mind, the present article wishes to understand the role of Europol in the development of a European policy to counter the illegal use of the internet. The article proposes to reach this objective by analyzing, through the theoretical lenses of experimental governance, the evolution of this agency’s activities in the area of cyber crime and cyber security, its positioning as an expert in the field, and the consequences for the way this policy is currently developing and is expected to develop in the near future.
