The applied computer science of economic analyses: Internet prioritization and Internet pricing, and software engineering and software pricing for the mass market

This research examines evolving issues in applied computer science and applies economic and business analyses as well. There are two main areas. The first is internetwork communications as embodied by the Internet. The goal of the research is to devise an efficient pricing, prioritization, and incentivization plan that could be realistically implemented on the existing infrastructure. Criteria include practical and economic efficiency, and proper incentives for both users and providers. Background information on the evolution and functional operation of the Internet is given, and relevant literature is surveyed and analyzed. Economic analysis is performed on the incentive implications of the current pricing structure and organization. The problems are identified, and minimally disruptive solutions are proposed for all levels of implementation to the lowest level protocol. Practical issues are considered and performance analyses are done. The second area of research is mass market software engineering, and how this differs from classical software engineering. Software life-cycle revenues are analyzed and software pricing and timing implications are derived. A profit maximizing methodology is developed to select or defer the development of software features for inclusion in a given release. An iterative model of the stages of the software development process is developed, taking into account new communications capabilities as well as profitability. ^

Reading comprehension and mathematical concept acquisition through the use of math stories with bilingual children

Math storybooks are picture books in which the understanding of mathematical concepts is central to the comprehension of the story. Math stories have provided useful opportunities for children to expand their skills in the language arts area and to talk about mathematical factors that are related to their real lives. The purpose of this study was to examine bilingual children's reading and math comprehension of the math storybooks. ^ The participants were randomly selected from two Korean schools and two public elementary schools in Miami, Florida. The sample consisted of 63 Hispanic American and 43 Korean American children from ages five to seven. A 2 x 3 x (2) mixed-model design with two between- and one within-subjects variable was used to conduct this study. The two between-subjects variables were ethnicity and age, and the within-subjects variable was the subject area of comprehension. Subjects were read the three math stories individually, and then they were asked questions related to reading and math comprehension. ^ The overall ANOVA using multivariate tests was conducted to evaluate the factor of subject area for age and ethnicity. As follow-up tests for a significant main effect and a significant interaction effect, pairwise comparisons and simple main effect tests were conducted, respectively. ^ The results showed that there were significant ethnicity and age differences in total comprehension scores. There were also age differences in reading and math comprehension, but no significant differences were found in reading and math by ethnicity. Korean American children had higher scores in total comprehension than those of Hispanic American children, and they showed greater changes in their comprehension skills at the younger ages, from five to six, whereas Hispanic American children showed greater changes at the older ages, from six to seven. Children at ages five and six showed higher scores in reading than in math, but no significant differences between math and reading comprehension scores were found at age seven. ^ Through schooling with integrated instruction, young bilingual children can move into higher levels of abstraction and concepts. This study highlighted bilingual children's general nature of thinking and showed how they developed reading and mathematics comprehension in an integrated process. ^

Experiential hospitality environments: The roles of the interior architectural features in affording meanings of place

People’s authentic sense of place is being overshadowed by less authentic experiences referred to as placelessness. Consequently, a demand for experiential interior environments has surfaced. Experiential environmental and place attachment theories suggested that the relationships between self, others, and the environment are what encourage users in creating meaningful authentic experiences. This qualitative study explored the roles of the experiential interior architectural features in affording users of hospitality environments higher-level needs, such as meanings of place. For the case study, ten participants stayed at a hotel for two nights. Participants were given a guided list of ten facets of an experience, which was insidiously structured by both experiential environmental and place attachment theories. The participants used photographs to document each of the facets on the guided list. The photos were then used during the photo elicitation interviews, which evoked additional qualitative information. Participants identified specific interior architectural features and described them using the themes associated to place attachment theories. The findings revealed that the interior architectural features might enrich the meanings a person associates with a given place. Possibly affording users higher-level needs. As a result, if an experiential interior environment allows users to foster relationships between self, others, and the physical environment, they may experience more authentic experiences and give more meanings to a place.

Recognizing the Value of Teaching Proverbs: Multicultural Origins of Oral and Written Literacy

The purpose of this paper is to explore the use of multicultural proverbs in interdisciplinary and cross-cultural instruction through the language arts, history and social sciences. Educators can use proverbs to engage students in learning, enhance their understanding of other cultures and languages, and promote a globally-sensitive community.
