Underlying processes in the poor response inhibition of children with Attention-Deficit/Hyperactivity Disorder

  • Description: This study evaluated the effects of reward, punishment, and reward + punishment on the impulsive responses of ADHD children. The impulsive responses of ADHD and normal control boys (30 per group) were compared during performance of a go/no-go task, administered under reward-only, punishment-only, and reward + punishment conditions. When differences in aggression, anxiety, and IQ between these groups were controlled for, results indicated that the impulsivity levels of the ADHD group were higher than the control group in all three reinforcement conditions. Also, the ADHD group was more impulsive in the reward + punishment condition, compared to the reward-only and punishment-only conditions, and there was no difference between the reward-only and punishment-only conditions. The control groups showed no difference across the three reinforcement conditions. These findings raise the possibility that the poor response inhibition of ADHD children may be related to both a generalized inhibitory deficit and a response modulation deficit.

  • Description: G.J. DuPaul (2003) offered two suggestions for additional research to understand the strong source effects reported by R. Gomez, G. L. Burns, J. A. Walsh, and M. A. de Moura (2003) in attention-deficit/ hyperactivity disorder (ADHD) rating scales. The first suggestion was to determine whether the source effects represent mostly bias or accuracy. The second suggestion was to minimize source effects through the development of better ADHD rating scales. Because source effects can represent bias or accuracy, it is important to minimize the bias aspect through content validation procedures prior to attempts to determine whether source effects better reflect bias or accuracy. This comment offers various suggestions to reduce the bias in ADHD rating scales.

Understanding the dynamics of the Australian accounting profession : A prosopographical study of the founding members of the Incorporated Institute of Accountants, Victoria, 1886 to 1908

  • Description: Numerous studies have examined the institutional setting of accounting as a professional occupation. However, institutional deeds and outcomes derive from the behaviour of individual actors, particularly those key players who drive the creation, policy development and outlook of practitioner associations. Recognising this, and in search of a more detailed understanding of the dynamics of professional formation, this study applies the prosopographical method of inquiry to accounting development in Australia during the period 1886 to 1908. Motives and actions are identified with the founding members of the Incorporated Institute of Accountants, Victoria, during this formative era, which saw key personalities transfer their allegiance to the Australasian Corporation of Public Accountants. The beliefs, preferences and ambitions of individual participants are shown to exert significant influence over the process of professional formation, highlighting the capacity of prosopographical studies to augment the predominantly vocational and institutional focus of the prior sociology of professions literature.

  • Description: We examine various methods for data clustering and data classification that are based on the minimization of the so-called cluster function and its modications. These functions are nonsmooth and nonconvex. We use Discrete Gradient methods for their local minimization. We consider also a combination of this method with the cutting angle method for global minimization. We present and discuss results of numerical experiments.

  • Description: Chronic illness frequently contributes to diminished levels of activity, a consequent increased dependence on health related support services and reduced quality of life. Surprisingly few studies have described activity among people with end-stage renal disease (ESRD). The current study examined the utility and validity of the Human Activity Profile (HAP) for describing activity in a sample of Australians with ESRD. A descriptive design supported the primary objective of validating the use of HAP for an Australian renal population. Data was collected from 65 adults with ESRD under the care of one regional and one metropolitan renal unit in Victoria. The HAP measures physical activity across a range of activities of daily living, including a dyspnoea scale. The Sickness Impact Profile (SIP) describes activities associated with daily living in the areas of physical, psychological and independence. The HAP, SIP and a questionnaire summarising demographic and diagnostic details were administered while each person was undergoing dialysis and the results subsequently compared. This study demonstrates that HAP is a valid measure of activity levels for people with ESRD undergoing maintenance haemodialysis. Additionally, scores on SIP and HAP indicate that this group have low levels of daily activity. These findings support the use of HAP in research to understand the activity levels of ESRD patients and the factors associated with decline.

  • Description: The Internet and portability of technologies are changing the way we are doing business. Electronic business and commerce (e-commerce) platforms purportedly provide companies of all sizes with opportunities for economies of scale, process efficiencies and mechanisms for electronic advertising, retailing, trading and transaction. Australian small and medium size enterprises (SME) have, however, been reluctant to embrace information and communication technologies (ICT) and e-commerce because they fail to see the value of such tools. While SME are still coming to terms with core ICT adoption and strategic e-commerce directions, individual SME connectivity and e-commerce adoption inertia has been upstaged by collaborative network trends. Competitive advantage is becoming embedded in collaboration, networking and (virtual) clustering. This paper discusses the pathways towards online collaboration that address both industry or network needs and the capabilities, needs and attitudes of individual SME.

What does it take to get to the top : Do middle and senior managers agree?

  • Authors: Wood, Glenice

  • Description: Women constitute only approximately 3-5 per cent of Australian senior managers. One possible explanation of their failure to enter senior management in greater numbers is that women in management may have differing perceptions of the necessary prerequisites for promotion to senior roles. This study explored this possibility with 351 male and 156 female Australian middle managers, whose views were contrasted with senior managers’ perceptions. Gender differences in perception were found between middle managers and middle and senior managers in terms of the importance placed on personal qualities such as attractiveness, deference to superiors, likeability, personality, popularity and powerful allies (perceived charisma) as attributes considered necessary for achieving senior management promotion. In particular, female middle managers believed more strongly than their male counterparts, that senior managers would value the personal qualities encompassed in perceived charisma when considering middle managers for further promotion. However, senior managers did not consider this group of attributes to be important in promotion-seeking behaviour.

  • Description: In this paper is presented an hybrid algorithm for finding the absolute extreme point of a multimodal scalar function of many variables. The algorithm is suitable when the objective function is expensive to compute, the computation can be affected by noise and/or partial derivatives cannot be calculated. The method used is a genetic modification of a previous algorithm based on the Prices method. All information about behavior of objective function collected on previous iterates are used to chose new evaluation points. The genetic part of the algorithm is very effective to escape from local attractors of the algorithm and assures convergence in probability to the global optimum. The proposed algorithm has been tested on a large set of multimodal test problems outperforming both the modified Prices algorithm and classical genetic approach.

  • Description: In this paper, we propose a new method for the unconstrained minimization of a function presented as a difference of two convex functions. This method is based on continuous approximations to the Demyanov-Rubinov quasidifferential. First, a terminating algorithm for the computation of a descent direction of the objective function is described. Then we present a minimization algorithm and study its convergence. An implementable version of this algorithm is discussed. Finally, we report the results of preliminary numerical experiments.

A model of knowledge acquisition that refocuses knowledge management

  • Authors: Van Beveren, John

  • Description: This paper presents a model of knowledge acquisition from definitions of data, information and knowledge. The model asserts that knowledge cannot exist outside of the human brain, and that any expression of the knowledge requires it to be transformed into information to be communicated outside of the brain. The model asserts that information is acquired through the sensors to the brain where it is processed with prior knowledge and that new knowledge can be created from the processing of information within the brain only. From a discussion of this model in the context of alternative viewpoints, it is concluded that the future focus for knowledge management should be toward human resource strategies that leverage human-intellectual capital within firms and for the dissemination and sharing of important information that promotes creativity and innovation within and between employees.

A political economy approach to the neoclassical model of transition

  • Reviewed:
  • Description: The neoclassical model of transition from a centrally-administered socialist economic system to a market-based economic system was implemented in Russia and Eastern Europe. The neoclassical process took the form of either shock therapy or gradualism. However, each approach actually involved a combination of shock therapy and gradualist policies, making the distinction between the two approaches unfounded. In addition, both approaches suffered by the innate inadequacies of neoclassical economic analysis as being politically/institutionally naked. Both shock therapy supporters and gradualist neoclassical economists did not provide a specific process of institutional development, favouring a gradual market-driven institutional outcome. With regard to the political structure, democracy was inconsistent with shock therapy, while active state intervention during transition was inconsistent with the ultimate goal of the gradualist neoclassical economists of competitive capitalism.

A post Keynesian critique of privatization policies in transition economies

  • Description: The privatization policies implemented in transition economies were based on the neoclassical principles of economic thought. The neoclassical privatization policies contributed to the well-known results of a large reduction in output, high unemployment and inflation and a breakdown of institutional norms resulting in corruption and illegal activities. For the post Keynesians, there could have been a transition to a market economy without a substantial change in property ownership. This was because ownership, as such, was less important than competition, the incentive structure and the nature of regulatory policies. Consequently, post Keynesian policies of privatization would had resulted in a substantially smaller social cost of transition. Copyright © 2002 John Wiley and Sons, Ltd.
