Gis, Modeling And Human Civilization: The Birth Of Geo-social Engineering

Description: Computer-based, mathematical models have significant value in describing the processes behind urban development and its inhabitants. The following research describes the theories and concepts behind modeling and offers insight into the potential future of the field. First, the research covers a brief history of applicable modeling strategies. This is followed by a summary of current popular approaches. The numerical background of geo-social engineering is developed through mathematical techniques. Geo-social engineering is the integration of modeling into the basic design human civilization. The mathematical models will be incorporated into a design of a computer program. From this, a possible geo-social model structure is presented and its architecture is described.

Biological Inhibitors

Description: Four isosteric series of plant growth-regulating compounds were prepared. Using an Avena sativa coleptile assay system, derivatives in series I and IV inhibited segment elongation to a greater degree than did comparable derivatives in series II and III.

Brain Growth Spurts and Plateau Periods in Normal Elementary School Pupils

Description: The purposes of this study were to determine whether brain growth spurts occur in normal pupils and to determine whether there was a uniform difference in head circumference between boys and girls. Subjects were 3,062 normal elementary pupils, grades one through six, from one suburban school district. Fiberglass measuring tapes were used to measure pupils' head circumference. The hypotheses of the study predicted that the relationship between head circumference and age would be linear. Further, it was predicted that the differences in head circumference between boys and girls would be uniform over seven specified ages. The first hypothesis was tested using a test for linear trend and deviation from linear trend using the General Linear Models procedure. The results indicated that there was a significant linear trend between head circumference and age. The test for deviation from the linear trend was not significant. This would suggest that any deviation from a straight line observed in the data can be attributed to chance. It was concluded that since there was no significant deviation from linear trend, it would suggest a continuous growth of the brain for the ages included in this study. A two-way analysis of variance was used to test the second hypothesis. The results indicated that the male mean head circumference was significantly larger than that of the female in all age groups. As the interaction of sex and age groups was tested, there was no interaction between sex and age groups. It was concluded that since the interaction between sex and age groups was not significant, there is no indication of differences in the rates of brain growth between boys and girls.

Effects of an electric field on water uptake in single roots of intact onion plants

Description: Water uptake by a single root of an onion plant (Allium cepa) was measured potentially before, during and following exposure of shoots to an external electric field (EEF). The field strength used was 9kV/m DC and AC (60-Hz) brought about a statistically significant increase (44-71%) in water uptake if the shoot chamber was at almost 100% humidity.

A Technique for Quantifying Forest Stands for Management Evaluations

Description: "In this study, a system for describing the three-dimensional geometry of trees and stands is presented. The system consists of two survey instruments, a theodolite and transit, and basic triangulation principles. A spotting laser has recently been added to the system to facilitate the spotting of the tree nodes to be surveyed" (p. ix). Results show significant differences in tree productivity as a result of fertilization and changes in heights, bole diameters, etc.

The Role of Self-Compassion in Posttraumatic Growth

Description: Although the experience of trauma is associated with a great deal of psychological distress, it may also lead to meaningful positive change, known as posttraumatic growth (PTG), evidenced as progression in areas of life appreciation, intimacy in relationships, sense of personal strength, new possibilities, and spiritual development. Utilizing an acceptance and commitment therapy (ACT) perspective, the current study explored whether self-compassion helped to explain the willingness to approach and make sense of a trauma, leading to growth. A sample of 758 undergraduate students completed online self-report questionnaires, and results suggested that self-compassion does partially predict PTG and support for how self-compassion may be understood in relation to PTG is provided. Implications of the current study's findings, as well as suggestions for future research related to trauma within a college population, are discussed.

The Modified Human Need Survey of Human Needs

Description: This study was designed to test the hypothesis that desire is inversely proportional to satisfaction in the motivational category of a given person. The present study represents an attempt to devise an objectively scored test which will objectively and empirically determine the level of motivation of a given subject.

Phosphorus Metabolism in Atypical Mycobacteria

Description: The design for this study was tri-phasic: 1) to establish growth time patterns for each group of atypical mycobacteria, 2) to demonstrate the dynamic state of phosphorus in the various fractions by determining its incorporation and turnover, 3) to determine quantitatively the amount of phosphorus in each fraction.

Event Centrality: Debunking the “Bad Science” Myth That Self-reported Posttraumatic Growth Does Not Reflect Positive Change

Description: Despite strong evidence supporting the existence of posttraumatic growth (PTG), some investigators question whether the construct measured by the Posttraumatic Growth Inventory (PTGI) is that of perceived growth or “actual” growth. In a replication of a recent investigation, the present study sought to refine the methodology used by employing the construct of event centrality. Due to its limited sample size, the results of this analysis did not provide strong evidence in support of the hypothesis that limiting analyses to individuals rating their trauma as high in event centrality improves the ability of the PTGI to reflect “actual” growth. However, results did support the idea that investigations of PTG conducted immediately following a trauma may be more reflective of a coping process, rather than growth. Further research is warranted to investigate the role of event centrality in posttraumatic growth, and the effect of time on the progression of growth following trauma.

Economic Growth Slower Than Previous 10 Expansions

Description: This report briefly discusses the recent pace of economic growth in the United States. A recent poll found that nearly 60% of U.S. adults believe that the economy is performing poorly. Although this expansion is already the fourth longest since the 1850's (34 quarters to date), the slow pace of economic growth means the overall gains have been relatively small.

Slow Growth in the Current U.S. Economic Expansion

Description: This report summarizes the U.S. economic growth record and reviews a number of explanations forwarded by economists for why this expansion has featured slow growth. Some explanations focus on short-term factors that would not be expected to persist, while others focus on long-term changes to the economy. The report does not discuss labor market conditions, except in the context of how they contribute to the pace of GDP growth.
