This study was undertaken in an effort to relate ANVIS-6 Night Vision Goggle image quality to user performance. The purpose was to determine which of five image quality metrics best related to performance tasks. The image quality metrics examined Modulation Transfer Function Area (MTFA), Integrated Contrast Sensitivity (leS), Square Root Integral (SQRI), Resolution, and Signal-to-Noise Ratio (SNR). The performance tasks were detection and recognition of targets under various levels of moon illumination. The metric that best related to target detection was SNR. The SNR results are consistent with visual psychophysics and SNR effects. The metric that best related to target recognition was Resolution. The resolution results are consistent with the position that recognition performance improves for suprathreshold targets as resolving power increases. / Master of Science

The purpose of the study is to determine the dark adaptation of second grade children in Denton, Texas.

The present study is part of a long time cooperative study of the Education and Home Economics Departments of North Texas State Teachers College begun in 1940. The purpose is to compare the dark adaptations of second and third grade children made in 1940 with those made in 1941, and to determine also the dark adaptation of a group of fifth and sixth grade children receiving vitamin A concentrate.

In landscape architecture, site inventory is a common precursor and perpetual informant of site design, toolkit development, and best management practices. Within inventory-specific texts, inventory is primarily geared, collected, and applied toward the daytime, and thusly, one might consider the bulk of inventory to be “daytime inventory” which pays greater heed to a diurnal humanity and lesser heed to the nocturnal world. With a greater attention to nighttime site conditions, we explored “nighttime inventory” through a series of primary considerations - nighttime lighting, light pollution, site ecology, and the night sky – along with several secondary considerations. We then surveyed 811 landscape practitioners from 12 states - receiving 51 responses - and via Likert, open-response, and yes/no inquiries; we assessed whether practitioners acknowledge and/or design per those nighttime considerations in their professional practice. Summarily, we found landscape practitioners paid less heed to nighttime inventory considerations – with some notable exceptions.

An increasing number of mainland Chinese tourists are coming to Taiwan and offer material benefits for many vendors on Taipei's night markets. Using in-depth interviews, this thesis examines the effect of mainland Chinese tourists on attitudes of the night market vendors at Ningxia Night Market in Taipei on China related topics. The difference in economic transactions with Chinese tourists offers a possibility to study the influence of the related rational incentives and contact on policy attitudes and opinions toward: Chinese tourists, cross-Strait economic integration and the alienation from the PRC. Taking into account the variables of business transactions and identity, the study analyzes 22 interviews of night market vendors and suggests that vendors with more business transactions with Chinese tourists tend to have more favorable views on two of the three investigated attitudes. Vendors with more benefits from the increase in tourists also show a considerable amount of pragmatism in their opinions, which leads the study to assume a strong positive influence of economic incentives when compared to another possible factor like contact. While negative effects can be caused by identity, contact and incentives, the positive influence in this framework seems to be mainly affected by the incentives.
