A Model of Intervention in Childhood
This paper describes a model and resulting simulations to assess the appropriate age structure of intervention in childhood on the theme: should we intervene early or late? We use asset theory approaches to construct a general model of state investment whose aim is to reduce inequality in human capital. We set out the key parameters of such a model, clarifying the assumptions that must be made by state planners or economists in assessing the relative value of targeted investment at different ages in the presence of a range of elements of uncertainty. We simulate the model showing how the age-investment schedule will vary under different assumptions. Early investment is highly valued because of the likely decline with age in effectiveness but the trade-offs are strongly moderated by other important assumptions around which there is uncertainty or are choice variables of the state planner.
A CLIPS prototype for autonomous power system control
The model of the system assumes a constant power source and loads (experiments) whose power demands exceed the supply. Experiments are described by their name, power consumption, time for a complete run, present status and the state of the load. The power consumption of each load is set at a constant level but can be dynamically modified by the operator. The status specifies if the experiment is running, paused, completed or failed. The state compensates for the lack of actual feedback sensor data, by signifying the stability of the load. Experiments are scheduled to keep as many running as possible with the current system limitations. A graphics oriented user interface is embedded into the rule-based system to enable an operator to easily experiment with the system
Neuro-memristive Circuits for Edge Computing: A review
The volume, veracity, variability, and velocity of data produced from the
ever-increasing network of sensors connected to Internet pose challenges for
power management, scalability, and sustainability of cloud computing
infrastructure. Increasing the data processing capability of edge computing
devices at lower power requirements can reduce several overheads for cloud
computing solutions. This paper provides the review of neuromorphic
CMOS-memristive architectures that can be integrated into edge computing
devices. We discuss why the neuromorphic architectures are useful for edge
devices and show the advantages, drawbacks and open problems in the field of
neuro-memristive circuits for edge computing
Toni Morrisson and the translation of history in Margaret Garner
This article probes how Toni Morrison translates biographical history in Margaret Garner in relation to Black women's self-determination. Margaret Garner was regarded with both reproach and reverence for murdering her two-year-old daughter to prevent the child from being returned to slavery after they escaped in 1856. Writing the 2005 opera Margaret Garner, Morrison made a number of changes to the historical narrative of the eponymous heroine. The focus of her translation is not on presenting an accurate recountal of history; rather, the goal is to redress the limitations placed on Black women's self-determination by granting them agency through this interpretation of Garne
THE ECONOMIC VALUE OF HIKING: FURTHER CONSIDERATIONS OF OPPORTUNITY COST OF TIME IN RECREATIONAL DEMAND MODELS
The paper tests two alternative specifications for the opportunity cost of time in travel cost models. The standard travel cost survey design is enriched to include a contingent valuation type question about peoples' willingness to accept compensation to forgo a precisely defined recreational experience. It is hypothesized that individually revealed value of time more appropriately reflects the opportunity costs of time associated with a particular aspect of recreation than the wage rate which measures the trade-off between work and leisure generally. The results seem to indicate a better overall fit for the models with the elicited value of individual consumer's time than for the models with the more traditional hourly earnings (wage rates). The importance of the corrected measurement of the opportunity cost time is illustrated by showing that estimated consumer surpluses based on two different value of time measurements differ significantly.Recreation demand, Travel cost model, Value of time, Resource /Energy Economics and Policy,
