State convergence and keyspace reduction of the mixer stream cipher

This paper presents an analysis of the stream cipher Mixer, a bit-based cipher with structural components similar to the well-known Grain cipher and the LILI family of keystream generators. Mixer uses a 128-bit key and 64-bit IV to initialise a 217-bit internal state. The analysis is focused on the initialisation function of Mixer and shows that there exist multiple key-IV pairs which, after initialisation, produce the same initial state, and consequently will generate the same keystream. Furthermore, if the number of iterations of the state update function performed during initialisation is increased, then the number of distinct initial states that can be obtained decreases. It is also shown that there exist some distinct initial states which produce the same keystream, resulting in a further reduction of the effective key space

Strategy taxonomy and classification system development : study of two state governments

There is limited understanding about business strategies related to parliamentary government's departments. This study focuses on the strategies of departments of two state governments in Australia. The strategies are derived from department strategic plans available in public domain and collected from respective websites. The results of this research indicate that strategies fall into seven categories: internal, development, political, partnership, environment, reorientation and status quo. The strategies of the departments are mainly internal or development where development strategy is mainly the focus of departments such as transport, and infrastructure. Political strategy is prevalent for departments related to communities, and education and training. Further three layers of strategies are identified as kernel, cluster and individual, which are mapped to the developed taxonomy.

Violence Against Women: Myths, Facts, Controversies

In Violence Against Women, award-winning author Walter S. DeKeseredy offers a passionate but well-documented sociological overview of a sobering problem. He starts by outlining the scope of the challenge and debunks current attempts to label intimate violence as gender neutral. He then lays bare the structural practices that sustain this violence, leading to a discussion of long- and short-term policies to address the issue. DeKeseredy includes an examination of male complicity and demonstrates how boys and men can change their roles. Throughout, he responds to myths that dismiss threats to women's health and safety and provides an impassioned call to action for women, men, and policymakers.
