For accurate prediction of normal tissue tolerance, it is important that the volumetric information of dose distribution be considered. However, in dosimetric optimization of intensity modulated beams, the dose-volume factor is usually neglected. In this paper we describe two methods of volume-dependent optimization for intensity modulated beams such as those generated by computer-controlled mu...

Creating a vertical scale involves several decisions on assessment designs and statistical analyses to determine the most appropriate vertical scale. This research study aims at investigating common item stability check procedures to arrive at vertical linking item sets that will produce the necessary constants for computing vertical theta (ability) estimates and scale scores on a vertical scal...

introduction: nowadays, hiv is mostly spreading in asian countries. one of the important routes for hiv transmission in these countries is the vertical route which infects 35% to 45% of newborns. mother’s education, drug prophylaxis and cesarean section, accompanied by banning breastfeeding will decrease this rate to 2%. therefore, mothers’ knowledge about prevention of mother to child transmis...

Five BASIC programs to select random samples from populations or to randomize treatments are presented. Program 1 is used to obtain randomization of any number of treatments in an equal number of positions or test units for any number of replicates. Program 2 produces latin squares of any size for treatment randomization. Program 3 is used to obtain a specific number of randomly selected sample...

This paper outlines the complex contemporary milieu of Australian teacher education within which curriculum leaders responsible for designing teacher education programs must make their program design decisions. Particular attention is paid to the collision of vertical (‘hierarchical’ or 'academic rationalist') and horizontal (‘flat’ or 'student-centred') curriculum discourses as a program desig...

This case study discusses the role of education, curriculum development, research, and service in supporting information systems for crisis response management. The study describes the Council for Emergency Management and Homeland Security (CEMHS) organization that designs and develops academic programs and courses in these specialized areas. CEMHS combines all levels of education in California...

To identify preoperative factors which influence the effectiveness of strabismus surgery in adults, we retrospectively reviewed the records of 179 patients > 15 years old (131 with exotropia, 48 with esotropia) who had had combined recession and resection surgery for correction of horizontal strabismus. Eighteen preoperative variables were evaluated; those with significant influence on the surg...

Background Vertically oriented global health initiatives (GHIs) addressing the HIV/AIDS epidemic, including the President’s Emergency Plan for AIDS Relief (PEPFAR), have successfully contributed to reducing HIV/AIDS related morbidity and mortality. However, there is still debate about whether these disease-specific programs have improved or harmed health systems overall, especially with respect...

wolbachia is an intracellular endosymbiont, which can induce thelytokous parthenogenesis in trichogramma egg parasitoids with the infected females producing daughters without any mating. with regard to the usual transfer of wolbachia which is vertical from the mother to her offspring through the cytoplasm of eggs, this manipulation of host’s reproduction can enhance its transmission to future g...
