in consideration of the commitment of the agent to the contract,indirect representation is divided in two kind of direct and indirect representation. indirect representative who acts in the name of himself and on behalf of the principal is bound with the contract himself and is commited to transfer(deliver) rights of the contract to the principal,so indirect representation has an important role...

abstract intensive and inefficient use of energy leads to degradation of natural resources and environmental problems. this study evaluated the relationship between the energy of consumed inputs and yield of tomato, cucumber and melon using the cobb–douglas production function. the data were collected from 90 farmers in firoozabad using a questionnaire. the farmers were chosen by simple random ...

We compared the effects of direct and indirect reinforcement contingencies on the performance of 6 individuals with profound developmental disabilities. Under both contingencies, completion of identical tasks (opening one of several types of containers) produced access to identical reinforcers. Under the direct contingency, the reinforcer was placed inside the container to be opened; under the ...

1 Feedback is critical in both human and computer tutoring because it has directive, facilitative, and motivational functions. An understanding of the feedback strategies of expert human tutors is essential for ITSs that aspire to model such tutors. Although previous research suggests that expert tutors provide indirect and delayed feedback, methodological concerns limit the generalizability of...

Classical association rules, here called “direct”, reflect relationships existing between items that relatively often co-occur in common transactions. In the web domain, items correspond to pages and transactions to user sessions. The main idea of the new approach presented is to discover indirect associations existing between pages that rarely occur together but there are other, “third” pages,...

OBJECTIVE The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) includes significant changes to Criterion A for posttraumatic stress disorder (PTSD), the criterion that defines which events qualify as "traumatic." This systematic review explores the fundamental question of how to define a trauma by reviewing the difference between direct and indirect trauma expo...

This study employs the framework of responses proposed by Harris (1991), notion implicature as defined Thomas (1995), and dimensions resistance introduced Clayman (2001) to examine types in Malaysian Parliamentary Question Time. Analysis revealed tendency using direct, indirect, evasive specific questions for various reasons. Direct answers were observed that could reflect positively on governm...

BACKGROUND, AIM, AND SCOPE In response to concerns about chemical substances that can alter the function of endocrine systems and may result in adverse effects on human and ecosystem health, a number of in vitro tests have been developed to identify and assess the endocrine disrupting potential of chemicals and environmental samples. One endpoint that is frequently used in in vitro models for t...

This paper discusses a methodology to manage wireless sensor networks (WSN) with self-organising feature maps, using co-operative Extended Kohonen Maps (EKMs). EKMs have been successfully demonstrated in other machine-learning contexts such as learning sensori-motor control and feedback tasks. Through a quantitative analysis of the algorithmic process, an indirect-mapping EKM can self-organise ...
