Rounding the bases with a secure base

Attachment & Human Development, 2016
Parental availability and responsiveness were experimentally manipulated to determine the effects on children's athletic performance. Fifty children (3-12-year-olds) ran as fast as possible around a softball diamond twice: once while parents were available and responsive and once while parents were unavailable and unresponsive (engrossed in mobile ...

On Negative Bases

2009
We study expansions in non-integer negative base ? β introduced by Ito and Sadahiro [7]. Using countable automata associated with ( ? β)-expansions, we characterize the case where the ( ? β)-shift is a system of finite type. We prove that, if β is a Pisot number, then the ( ? β)-shift is a sofic system.

A RBAC-Based Policy Information Base

Sixth IEEE International Workshop on Policies for Distributed Systems and Networks (POLICY'05), 2005
This paper presents a framework for representing and distributing access control policies in distributed heterogeneous systems. Access control polices follow the RBAC (role based access control) model proposed by the NIST. The framework is based on the provisioning strategy defined by IETF, i.e., the RBAC information is represented in terms of a PIB ...

Ant-based and swarm-based clustering

Swarm Intelligence, 2007
Clustering with swarm-based algorithms is emerging as an alternative to more conventional clustering methods, such as hierarchical clustering and k-means. Ant-based clustering stands out as the most widely used group of swarm-based clustering algorithms.

“Evidence-based” or “logic-based” medicine?

Osteoporosis International, 2010
Low trauma fractures are the cardinal manifestation of osteoporosis. Their occurrence supersedes bone mineral density in deciding whether specific therapy is warranted. We therefore disagree with the notion that a densitometric threshold for treatment should be applied to patients over age 50 who suffer low trauma distal radius fracture.

Context-Based Naming in Information Bases

International Journal of Cooperative Information Systems, 1997
In information bases following semantic and object-oriented data models, logical names are used for the external identification of objects. Yet the naming schemes employed are not "natural" enough and several problems often arise: logical names can be ambiguous, excessively long, unrelated to or unable to follow the changes of the environment of the ...

The research base of community-based rehabilitation

Disability and Rehabilitation, 1999
This paper provides an overview of the current research on community-based rehabilitation (CBR) which can be found in the public domain. A brief background to the concept of CBR is given, and it is shown how much of this published research reflects the fundamental principles of CBR service delivery, technology transfer, community involvement, and ...

On context-based naming in information bases

Proceedings of CoopIS 97: 2nd IFCIS Conference on Cooperative Information Systems, 2002
In information bases following semantic and object-oriented data models logical names are used for the external identification of objects. Yet the naming schemes employed are not "natural" enough and several problems often arise: logical names can be ambiguous, excessively long, unrelated to or unable to follow the changes of the environment of named ...

Is Plant-Based Cardioprotection Evidence-Based?

Canadian Journal of Cardiology, 2014
Using natural products to reduce cardiovascular disease(CVD) risk is a topic of great interest to patients and healthcare providers. One such family of products is plant sterols orin saturated form, plant stanols, both of which are encom-passed by the term ‘phytosterols.’ Plant sterols and stanols arenaturally sourced in vegetable oils, cereals, nuts ...

Evidence-based and value-based paediatrics

The Lancet, 1999
This article reports the global expansion of scientific preventive medicine in the field of pediatrics. It has been reported that with improved hygiene sanitation and better nutrition has been proven to reduce infant mortality and produce the largest ever contribution to life expectancy by 30-40 years. Even the WHO came up with an estimate that by 2025
