Public vs. private sector : an examination of neo-liberal ideology

The paper reviews the theoretical underpinnings of the debate on the superiority of the public or private sector, and supports theoretical perspectives with help from empirical literature on the subject. The theoretical part covers issues relating to public choice, property rights and principal-agents relationship, while the empirical evidence includes review of literature on macroeconomic, microeconomic and welfare impacts of privatization. The paper finds that despite numerous studies and unending discussions, the debate on the superiority of the public or private sector has remained inconclusive and is likely to remain so in the future. Notwithstanding the practical difficulties of making this assessment, the paper concludes that this debate is more ideological rather than empirical, since it is not possible to determine the superiority of one over the other through case studies, which can only be selective in nature.New Public Management

Effective Early Childhood Programmes

Published in collaboration with the Open University, Early Childhood in Focus offers accessible and clear reviews of the best and most recent available research, information and analysis on key policy issues, offering clear messages on core policy topics and questions. This publication, the fourth in the series, looks at the policy issues surrounding the early childhood education and care programmes: there is compelling scientific evidence showing improved long-term outcomes for disadvantaged children who participate in a high-quality programme, but realising this potential through policies and programmes is far from straightforward. It tackles the issue in three parts: The case for early childhood programmes; Evidence for early childhood programme effectiveness; and Challenges for early childhood programmes

Conceptualising progression in the pedagogy of play and sustained shared thinking in early childhood education : a Vygotskian perspective

This paper is concerned specifically with the pedagogies applied in supporting learning through children‟s play, and it is framed outside mainstream discourses on the nature of play. The development of the paper also represents one stage in a continuing effort to develop a better understanding of sustained shared thinking in early childhood education. The paper also focuses on the educational potential of shared playful activities. However, given the overwhelming consensus regarding the importance of play in early childhood development, even a diehard educational pragmatist must begin by addressing subjects that are most commonly considered by psychologists. The paper begins with an account of „sustained shared thinking‟, a pedagogical concept that was first identified in a mixed method, but essentially educational effectiveness study. Then a consideration of the nature and processes of „learning‟ and „development‟ is offered. It is argued that popular accounts of a fundamental difference in the perspectives of Piaget and Vygotsky have distracted educational attention from the most important legacy that they have left to early childhood education; the notion of „emergent development‟. Pedagogic progression in the early years is then identified as an educational response to, and an engagement with, the most commonly observed, evidence based developmental trajectories of young children as they learn through play

Scaling power laws in the Sao Paulo Stock Exchange

The scaling of the probability distribution of the Sao Paulo Stock Exchange index is shown to be described by a Levy stable stochastic process for the modal region of the distribution. Data refer to daily records for the 30-year period 1968-1998. The truncated Levy process is characterized by a scaling index of 1.66. Scaling power laws are also shown to be present in the mean and standard deviation of the series as the time horizon is increased. A power law is also found for the autocorrelation time of the natural logs of the index series. The deviations from the line that best fits the natural logs of the series are also found to be short range autocorrelated and to follow an exponential decay.complex systems

not all asymptomatic carotid plaques are equal: some require intervention

Ischemic stroke represents a major health hazard around the world, which has a severe impact on society and the health-care systems. Roughly, 15% of all strokes can be attributed to significant atherosclerotic disease of the carotid arteries. Some patients presenting with disabling strokes for the first time cannot benefit from carotid revascularization having lost the opportunity of prevention. We know that all symptomatic patients were once asymptomatic. Hence, after identifying high risk carotid plaques and patient’s characteristics suitable for interventions, they should be offered carotid revascularization at specialized centers (with low perioperative stroke and death rates) to prevent stroke and cognitive function decline in long term

Manipulating cues in involuntary autobiographical memory: verbal cues are more effective than pictorial cues

In two experiments, pictorial cues were compared with their verbal labels to assess their effectiveness in eliciting involuntary autobiographical memories. Cues were relatively complex in Experiment 1 (e.g., relaxing on a beach) and simple objects in Experiment 2 (e.g., a ball). In both experiments, participants went through a vigilance task in which they were presented with frequent nontarget and rare target visual stimuli. Pictures or their corresponding verbal labels were also displayed on both target and nontarget stimuli, but participants were told that these were irrelevant to the task. They were asked to interrupt the vigilance task whenever they became aware of task-unrelated mental contents and to report them. In both experiments, more involuntary memories were elicited in the verbal cue condition, rather than in the pictorial cue condition. This result is discussed in relation to previous work that highlighted the greater effectiveness of verbal cues in memory tasks
