Outcome measures in assertive outreach : one team's journey towards a system of implementation

The article describes a team's efforts to develop a workable system of outcome measures as a means of supporting good practice and fostering meaningful therapeutic relationships with clients. The team identified their reasons for using outcome measures. Then, they considered what they wanted to measure. The Health of the Nation Outcome Scale was identified as the only compulsory outcome measure. Throughout the process, team members often expressed the need for the system to be workable.

Ethical practice in sex offender assessment : consideration of actuarial and polygraph methods

The current generation of community protection laws represents a shift in priorities that may see the individual rights of sex offenders compromised for the goal of public safety. At the center of many judicial decisions under these laws are the risk assessment reports provided by mental health practitioners. The widespread enactment of laws allowing for additional sanctions for sex offenders, and a burgeoning research literature regarding the methods used to assess risk have served to heighten rather than resolve the ethical concerns associated with professional practice in this area. This article examines ethical issues inherent in the use of two assessment methods commonly used with sex offenders in the correctional context, focusing on actuarial measures and polygraph tests. Properly conducted and adequately reported actuarial findings are considered to provide useful information of sufficient accuracy to inform rather than mislead judicial decision makers, although careful consideration must be given to the limitations of current measures in each individual case. Despite its increasing use, polygraph testing is considered controversial, with little consensus regarding its accuracy or appropriate applications. On the basis of the current state of the professional literature regarding the polygraph, its use with sex offenders raises unresolved ethical concerns.

Fast finite-time consensus of a class of high-order uncertain nonlinear systems

This paper poses and solves a new problem of consensus control where the task is to make the fixed-topology multi-agent network, with each agent described by an uncertain nonlinear system in chained form, to reach consensus in a fast finite time. Our development starts with a set of new sliding mode surfaces. It is proven that, on these sliding mode surfaces, consensus can be achieved if the communication graph has the proposed directed spanning tree. Next, we introduce the multi-surface sliding mode control to drive the sliding variables to the sliding mode surfaces in a fast finite time. The control Lyapunov function for fast finite time stability, motivated by the fast terminal sliding mode control, is used to prove the reachability of the sliding mode surface. A recursive design procedure is provided, which guarantees the boundedness of the control input.

Consensus control for a system of underwater swarm robots

The control of a swarm of underwater robots requires both a control algorithm and a communication system. Unfortunately, underwater communications is difficult at the best of times and so large time delays and minimal information is a concern. The control system must be able to handle a large number of robots without a master control, i.e., a decentralized control approach. This paper describes Consensus control as a way to decentralize. Consensus control allows each robot to know the final goal and then to decide, based on the position of the other robots, its best move to help achieve the goal.

Different personality measures for different business outcomes : a comparison of selection criteria used for a management training program

Reports a study in which the MBTI, FIRO-B and PP measures were correlated with employee performance indicators of high potential candidates for management development. The participants were 37 middle level managers in a large trans-national company. Results indicate a disturbing disconnect between measures used in training and development and actual business outcomes that can be presumed to express organisational priorities and goals.

From bivalves to birds : oxidative stress and longevity

1. The oxidative stress theory of ageing predicts that animals living longer will have less cumulative oxidative damage together with structural characteristics that make them more resistant to oxidative damage itself.
2. Although a general relationship between body size, metabolism and longevity does not exist in marine invertebrates, they are generally characterized by low rates of metabolism and reactive oxygen species (ROS) formation associated with lower antioxidant enzyme activities compared to vertebrates.
3. Birds and mammals have very similar size-affected metabolic rates and their metabolic intensity explains only some of the variation in maximum lifespan potential (MLSP).Within each class, smaller animals have higher rates of metabolism and ROS production and membranes that are more susceptible to oxidative damage and autocatalytic propagation of free radicals than larger ones.
4. Although the high variation in life-history strategies is accompanied by substantial variation in MLSP, there is a consistent positive correlation between rates of ROS formation and antioxidant levels among most animals examined so far for these traits. The consensus of these studies is that ROS and antioxidant levels are inversely related to MLSP.
5. The lack of a clear stoichiometric relation between variables contributing to oxidative stress limits our capacity to infer longevity consequences from measures of pro-oxidant or antioxidant status among or within species

Leader-follower consensus control of a class of nonholonomic systems

In this paper, we propose a systematic solution to the leader-follower consensus of a class of nonholonomic chained form systems. The control design, which is reminiscent of terminal sliding mode and multi-surface sliding mode control methods, is presented to guarantee the convergence of multiple sliding surfaces, which also implies the convergence of the proposed consensus error function. On these sliding surfaces, the desired leader-follower consensus can be reached for multi-agent network formed by the nonholonomic chained form systems.

Illusions of consensus : New South Wales stakeholders' constructions of the identity of history

This article analyses the relationships between the perspectives of stakeholders involved in the development of the 1998 New South Wales Stages 4–5 history syllabus. It examined four key issues that emerged in the debates about history education during the review and found that stakeholders' views diverged significantly on three of these issues. While loose coalitions formed around particular issues, stakeholders provided different rationales for their positions, and coalitions re-formed on other debates. The analysis highlights the divergence between stakeholders and between the Commonwealth and state governments and stakeholders on the desirable content and goals of history education. The findings indicate that consultation might not produce consensus, and that even the appearance of consensus can be grounded in substantively and philosophically different premises. In practical terms, the findings suggest that if the purpose of consultation as a method of curriculum development is to produce a syllabus that reflects the diverse perspectives held by stakeholders, then the syllabus structure needs to make provision for content options as well as common core areas of study.

A study on the accuracy of frequency measures and its impact on knowledge discovery in single sequences

In knowledge discovery in single sequences, different results could be discovered from the same sequence when different frequency measures are adopted. It is natural to raise such questions as (1) do these frequency measures reflect actual frequencies accurately? (2) what impacts do frequency measures have on discovered knowledge? (3) are discovered results accurate and reliable? and (4) which measures are appropriate for reflecting frequencies accurately? In this paper, taking three major factors (anti-monotonicity, maximum-frequency and window-width restriction) into account, we identify inaccuracies inherent in seven existing frequency measures, and investigate their impacts on the soundness and completeness of two kinds of knowledge, frequent episodes and episode rules, discovered from single sequences. In order to obtain more accurate frequencies and knowledge, we provide three recommendations for defining appropriate frequency measures. Following the recommendations, we introduce a more appropriate frequency measure. Empirical evaluation reveals the inaccuracies and verifies our findings. 

Monitoring the safe use of Clozapine : a consensus view from Victoria, Australia

Clozapine is an important antipsychotic agent that has a unique profile of clinical benefits, but that has also been associated with several serious and potentially life-threatening safety concerns. In order to minimise the impact of haematological adverse events, health professionals treating patients with clozapine are currently required to register their patients on a centrally administered data network and to conform to strict protocols. The consensus statement documented in this article extends existing protocols by recommending monitoring of patients treated with clozapine for additional adverse effects during treatment. This consensus statement reflects the current practice at five major public psychiatric hospitals in Victoria, Australia, for the monitoring and management of clozapine-related adverse events, and has been implemented at these sites because of emerging safety concerns associating clozapine with cardiovascular and metabolic adverse effects.
