this study extends prior researches by exploring the effect of organizational orientations on export performance. building on the already extensive literature, we developed a model of relationship. a total of 120 usable questionnaires were received from the iranian food industry smes. the results indicated that entrepreneurial orientation, market orientation and learning orientation positively ...

Axons and dendrites of neurons differ in the polarity orientation of their microtubules. Whereas the polarity orientation of microtubules in axons is uniform, with all plus ends distal, that in dendrites is nonuniform. The mechanisms responsible for establishment and maintenance of microtubule polarity orientation in neuronal processes remain unclear, however. We previously described a culture ...

Eye-specific thalamic inputs converge in the primary visual cortex (V1) and form the basis of binocular vision. For normal binocular perceptions, such as depth and stereopsis, binocularly matched orientation preference between the two eyes is required. A critical period of binocular matching of orientation preference in mice during normal development is reported in literature. Using a reaction ...

The effects of molecular orientation on electron transfer are explored in collisions between haloalkane molecules oriented in molecular beams and K atoms which have sufficient energy to allow the charged products to separate. For several molecules studied (CF3Br, CF3C1, and CH3Br) attack at the “heads” end of the molecule (the end with the most weakly bound atom) always produces more K+ ions. T...

the purpose of this study is to examine the relationship between epistemological and motivational beliefs about mathematics among gifted students. to this end , 334 first year high school gifted students were selected through applying the otis intelligence test. epistemological beliefs questionnaire (ebq) and motivational beliefs about mathematics scale (mbms) were also used as measurement inst...

School buildings forming a large part of public buildings are among the most important consumers of energy in Iran. Given the existing construction conditions, these buildings seem to have considerable potential for energy efficiency if the construction and design methods are reformed. Therefore, numerous researchers have analyzed geometrical factors influencing energy consumption in buildings,...

A model for end-stopping that requires only excitatory inputs is presented. This model is based on multiplication of the outputs from two orientation tuned and spatial-frequency selective neurons. Computer simulations show that, provided the optimal orientations of the two neurons are sufficiently different, the resulting product will display orientation-independent end-stopping. Neurons simula...
