test anxiety as a common disorder is a physiological condition in which students experience extreme stress, anxiety and discomfort during and/or before taking a test. this kind of anxiety results from the sense of threats like fear of failure, lack of confidence and setting unattainable goals in learning and wishing to be perfect in academic situation. resulting anxiety disrupts attention, memo...

Pearson product–moment correlations found significant relationships between students' grades in the online class and their GPA, attendance at a class orientation session, the number of previous course withdrawals, ASSET reading scores, the number of previous online courses, age, and ACT English scores. Regression analysis found that two variables serve as the best predictors: attendance at an o...

This paper discusses a method for finding near-optimal build orientations for shape deposition manufacturing (SDM). SDM is a solid freeform fabrication process that allows the creation of complex shaped parts by the iterative application of numerically controlled material deposition and milling operations. The part build time in SDM process depends on the number of layers. And the number of lay...

LetD be an acyclic orientation of a graphG.An arc ofD is said to be dependent if its reversal creates a directed cycle. Let d(D) denote the number of dependent arcs inD. Define dmin(G) (dmax(G)) to be theminimum (maximum) number of d(D) over all acyclic orientationsD ofG.We determine dmin(G) for an outerplanar graph G and prove that G has an acyclic orientation with exactly k dependent arcs if ...

poorinformative websites of hotels in iranian tourist destinations has turned to a deterrent factor in attracting potential tourists from all over the world. the main goal of this study was to identify effective solutions for improving the informative effectiveness of iranian top hotels’ websites based on interviews with 25 hotel managers (i.e. ceos, public relations managers and it managers). ...

Cell division orientation is crucial to control segregation of polarized fate determinants in the daughter cells to produce symmetric or asymmetric fate outcomes. Most studies in vertebrates have focused on the role of mitotic spindle orientation in proliferative asymmetric divisions and it remains unclear whether altering spindle orientation is required for the production of asymmetric fates i...

Current understanding in locomotion research is that, for humans, navigating natural environments relies heavily on visual input; in contrast, walking on even ground in man-made obstacle and hazard-free environments is so highly automated that visual information derived from floor patterns should not affect locomotion and in particular have no impact on the direction of travel. The vision liter...

An orientation of an undirected graph is a choice of direction for each of its edges. An orientation is called ideal with respect to a given set of pairs of vertices if it does not increase the shortest-path distances between the members of any of the pairs. A polynomial-time algorithm is given for constructing an ideal orientation with respect to two given pairs and any positive edge-lengths, ...

the increasing growth and development of communications technology has created a major change indifferent aspects of human life and organizational performance. new technologies have changed function and attitudes of individuals and organizations and have become an important aspect in creating new jobs and innovation in organizations. development of new phenomena such as electronic business, ele...

objectives: the present study explored the role of religious orientations to predict identity styles. in the past decades identity style has been one of the basic discussion in social and personality psychology. recently, religious orientation was converted to the core perspective in religious psychology. based on this, this study has been examined the role of religious orientations in predict ...
