This review synthesizes studies of the effects of modifying the academic calendar in Grades K-12 to do away with the long summer break while not increasing the length of the school year. The synthesis indicated that the quality of evidence on modified calendars is poor. Within this weak inferential framework, the average effect size for 39 school districts was quite small, d = .06, favoring mod...

We describe imprecise calendars, a way to organize and schedule clusters of nodes in a computation grid. Imprecise calendars permit the easy and efficient sharing of resources between different clusters of computers that are part of a computational grid. In addition, they can be used to provide specific time reservations for applications. We describe the algorithms and policies for manipulation...

Calendar data such as dates are probably more than any other data domain a subject to interpretation. Calendars are human abstractions of the physical flow of time predominately depending on culture, especially religion and history. They allow for measuring time in different units like day, week, working day, and also teaching term. The vision of the Semantic Web is to enrich the current Web wi...

We are investigating a formal representation of time units and calendars, as restricted temporal entities for reasoning about activities. We examine characteristics of time units, and provide a categorization of the hierarchical relations among them. Hence we define an abstract hierarchical unit structure (a calendar structure) that expresses specific relations and properties among the units th...

In one common variant of time-space synaesthesia, individuals report the consistent experience of months bound to a spatial arrangement, commonly described as a circle extending outside of the body. Whereas the layout of these calendars has previously been thought to be relatively random and to differ greatly between synaesthetes, Study 1 provides the first evidence suggesting one critical aspe...

In applications like nancial trading, scheduling, manufacturing and process control, time based predicates in queries and rules are very important. There is also a need to de ne sets of time points or intervals. We refer to these sets as calendars. This paper presents a system of calendars that allows speci cation of natural-language time-based expressions, maintenance of valid time in database...

Tracking falls among elders is challenging. In this reliability study, which took place between October 2007 and February 2008, the authors compared participants' daily recordings of falls on calendars with a telephone survey of recall of falls over the previous 3 months within the population-based MOBILIZE Boston Study cohort, a cohort of 765 elders. From the cohort, 218 participants were rand...

Web based calendars are a very intuitive way to organize and present large sets of chronologically related reporting objects. Each day or period of time becomes a link to the related content. Cell attribution, such as background colors (traffic lighting) and or pop up values, can also be used to enhance the information content for a calendar cell. This paper will show how SAS Proc Report can be...
