We set out to determine whether extra-striate ventral stream function was compromised in amblyopia and to compare any observed deficit with previous data on comparable dorsal stream function. We devised a multi-element orientation task where orientation coherence sensitivity could be measured in a comparable way to motion coherence. The use of spatial frequency narrowband elements allowed for a...

increasing non-oil exporting is among the most important concerns for iran. software industry is among the knowledge based and profitable ones. identification of factors affecting export performance of software developers can improve planning that in turn results in increasing software export. in this research a model consisting of seven important variables in software industries including: com...

oceanographic images obtained from environmental satellites by a wide range of sensors allow characterizing natural phenomena through different physical measurements. for instance sea surface temperature (sst) images, altimetry data and ocean color data can be used for characterizing currents and vortex structures in the ocean. the purpose of this thesis is to derive a relatively complete frame...

BACKGROUND Detection of visual contours (strings of small oriented elements) is markedly poor in schizophrenia. This has previously been attributed to an inability to group local information across space into a global percept. Here, we show that this failure actually originates from a combination of poor encoding of local orientation and abnormal processing of visual context. METHODS We measu...

the aim of this study was to determine the validity and reliability of moral orientation questionnaire in the student athletes. the statistical population consisted of physical education students of mashhad ferdowsi university (n=450). 186 subjects were selected randomly as the sample. 14-item moral orientation questionnaire (miltiadis, 2010) was used which included 2 factors (deontological eth...

OBJECTIVES Nurses need to be full partners in shaping health care and health care policy. One way to do this is to be present and active on boards at all levels. The purpose of this study is to examine the orientation experiences of nurses to boards and their preparation to influence health care and health care policy. METHODS A Web-based survey about the efficacy of board orientation was sen...

One of the most exciting and challenging tasks facing an epidemiologist working in a public health department is investigating an outbreak. Frequently, the cause and source of the outbreak are unknown. Sometimes large numbers of people are affected. Often, the people in the community are concerned because they fear more people, including themselves, may be stricken unless the cause is found soo...

We deene an algebra of ternary relations for cyclic ordering of 2D orientations. The algebra (1) is a reene-ment of the CYCORD theory; (2) contains 24 atomic relations, hence 2 24 general relations, of which the usual CYCORD relation is a particular relation; and (3) is NP-complete, which is not surprising since the CYCORD theory is. We then provide: (1) a constraint propagation algorithm for t...

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 ...

Polarization measurements are sensitive to the microstructure of tissues and can be used to detect pathological changes. Many tissues contain anisotropic fibrous structures. We obtain the local orientation of aligned fibrous scatterers using different groups of the backscattering Mueller matrix elements. Experiments on concentrically well-aligned silk fibers and unstained human papillary thyroi...
