An activity theory approach to affordance

Proceedings of the second Nordic conference on Human-computer interaction, 2002
The concept of affordance was introduced to the field of HCI as a means to enhance the understandability and usability of artifacts and especially their user interface. The results have however not been entirely convincing. This paper presents a theoretical analysis of the concept of affordance coined by James J. Gibson.

An Approach to the Antiinflammatory Activity of Borjatriol

Planta Medica, 1984
The antiinflammatory activity of borjatriol (a diterpenoid isolated from SIDERITIS MUGRONENSIS Borja) was tested using the cotton pellet-granuloma assay. The compound inhibited the granuloma weight and the serum lysozyme activity in a dose-dependently way.

A Factorization Approach for Activity Recognition

2003 Conference on Computer Vision and Pattern Recognition Workshop, 2003
Understanding activities arising out of the interactions of a configuration of moving objects is an important problem in video understanding, with applications in surveillance and monitoring. A special situation is when the objects are small enough to be represented as points on a 2D plane. In this paper, we introduce a novel method of representing the

A Nonparametric Approach for Active Contours

2007 International Joint Conference on Neural Networks, 2007
Active contours are commonly used in many image segmentation applications. There are different active contour definitions, but all active contour definitions in the literature use parametric forms to determine the shape priors or adjust the weighting of internal and external forces acting on the active contour.

An Approach to Semantics for UML Activities

2017
The precise semantics for UML Activities is must-have in automated applications of them. The paper proposes an approach to a definition of a semantics of a set of UML Activities in the form of LTS (Labelled Transition System). The set of activities is transformed to a graph of possible execution traces, using OCL (Object Constraint Language) operations.

An approach for profiling phishing activities

Computers & Security, 2014
Phishing attacks continue unabated to plague Internet users and trick them into providing personal and confidential information to phishers. In this paper, an approach for email-born phishing detection based on profiling and clustering techniques is proposed.

Supporting and maintaining derivations: A declarative active approach active approach

1997
Derivations in object-oriented databases are supported currently by means of imperative methods or by using deductive or even active rules. As imperative languages are difficult to analyze in order to extract dependencies, derivations are never maintaine and attributes are calculated each time they are requested.

Ancillary approaches to plasminogen activators

Annals of the New York Academy of Sciences, 2012
Acute ischemic stroke develops from an interruption in focal cerebral blood flow. In many cases, it is caused by an acute thromboembolism. Although systemic fibrinolytic therapy for acute ischemic stroke has been a significant breakthrough in the management of this disease, additional agents and methods that could improve or restore cerebral flow are ...

Activity Approach in Management

2017
Regardless of the field of activity, managers work with people. Not only those, who are called managers by their title, belong to the category of managers. Business owners and plant foremen, supervisors and heads of departments, commanders of military units and coaches of athletic teams, and many others - all fall into the category of managers by their

The Activity Approach: Death or Rebirth?

Russian Studies in Philosophy, 2001
In the not-too-distant past, the activity approach was quite popular in Russian philosophy and in many human sciences, including psychology. Recently it has come under criticism, even from some of its former proponents. This issue begins a series of articles devoted to assessing the results of research that has been conducted in Russia along the lines ...
