Making Memories: Why Time Matters
In the last decade advances in human neuroscience have identified the critical importance of time in creating long-term memories. Circadian neuroscience has established biological time functions via cellular clocks regulated by photosensitive retinal ganglion cells and the suprachiasmatic nuclei. Individuals have different circadian clocks depending on their chronotypes that vary with genetic, age, and sex. In contrast, social time is determined by time zones, daylight savings time, and education and employment hours. Social time and circadian time differences can lead to circadian desynchronization, sleep deprivation, health problems, and poor cognitive performance. Synchronizing social time to circadian biology leads to better health and learning, as demonstrated in adolescent education. In-day making memories of complex bodies of structured information in education is organized in social time and uses many different learning techniques. Research in the neuroscience of long-term memory (LTM) has demonstrated in-day time spaced learning patterns of three repetitions of information separated by two rest periods are effective in making memories in mammals and humans. This time pattern is based on the intracellular processes required in synaptic plasticity. Circadian desynchronization, sleep deprivation, and memory consolidation in sleep are less well-understood, though there has been considerable progress in neuroscience research in the last decade. The interplay of circadian, in-day and sleep neuroscience research are creating an understanding of making memories in the first 24-h that has already led to interventions that can improve health and learning

Analysis of Policy Issues Relating to Public Investment in Private Freight Infrastructure, MTI Report 99-03
The Norman Y. Mineta International Institute for Surface Transportation Policy Studies (IISTPS) at San José State University conducted this study to review the issues and implications involved in the investment of public funds in private freight infrastructure. After thorough legal research, the project team reached the following conclusions: LEGAL ANALYSIS: The California legislature has the legal power to invest public funds in privately-owned freight infrastructure projects State Highway funds, excepting gas tax revenues, may be used for investment in freight infrastructure projects. Gas tax revenues are restricted to highway use by current interpretations of the California Constitution. A challenge to this interpretation is not recommended. Gas tax revenues may be invested in roadway segments of freight infrastructure projects. RECOMMENDATIONS An analytical system of guidelines should be developed to score and evaluate any proposed freight infrastructure project. Economic development must be included in these scoring guidelines. Public agencies should maintain political contacts in order to control the political short-circuits of the planning process. The California Department of Transportation should develop a Freight Improvement Priority System for the purpose of prioritizing all freight improvement projects
A boy told me I was ugly. Voices of At Risk Adolescent Girls on Gender Identity and Dating Roles
Through an exploration of urban middle school girls’ Discourse, this study sought to investigate how at risk females defined their gendered identity. Based on an analysis of spoken and written Discourse in a Third Space writing group, we discovered that at risk girls’ notions of patriarchal dating roles, which were predicated upon ideas of physical attractiveness and “datability,” drove much of their perspectives about gender. This study reveals girls’ strong desire to conform and adhere to dating roles with boys despite their depiction of relationships as tumultuous, necessary, exciting, and inevitably painful. Implications for educators pertain to the importance of using Discourse as a tool to help understand and define gender struggles for at risk adolescent girls and the need for pedagogy that would encourage girls to safely work through the invisible constraints of gender
Chiral Symmetry Breaking in a Soft-Wall Model of AdS/QCD
We incorporate chiral symmetry breaking in a soft-wall version of the AdS/QCD
model by using a modified dilaton profile and a quartic term in the bulk scalar
potential. This allows one to separate the dependence on spontaneous and
explicit chiral symmetry breaking. The resulting mass spectra in the scalar,
vector and axial-vector sectors compares favorably with the respective QCD
resonances.Comment: Proceedings of "Crossing the Boundaries: Gauge Dynamics at Strong
