Engineering transport by concatenated maps

We present a generalized kick rotor model in which the phase of the kick can vary from kick to kick. This additional freedom allows one to control the transport in phase space. For a specific choice of kick-to-kick phases, we predict novel forms of accelerator modes which are potentially of high relevance for future experimental studies

Geophysical and Biological Reconnaissance of Rock Habitats in Western Camden Bay, Beaufort Sea, Alaska

This report presents the results of a 10-day geophysical and biological survey in western Camden Bay, in the Alaskan Beaufort Sea. The primary objective of this survey was to confirm the existence of boulders and cobbles on the seafloor as reported by Barnes (1981, 1982). The survey area extended from the eastern edge of the Canning River (mud flat area) to Kangigivik Point and seaward to the 14m contour line (Fig. 1). A solid boundary of pack ice prevented any survey work seaward of the 14m contour. We had proposed to examine the seabed to the 18m contour.This work was supported by the Bureau of Land Management through an interagency agreement with the National Oceanic and Atmospheric Administration, under which a multiyear program responding to needs of petroleum development of the Alaskan Continental Shelf is managed by the Outer Continental Shelf Environmental Assessment Program (OCSEAP) office

We collected samples or data with 98 individual deployments from 37 discrete stations (Table 2) along our cruise track. In addition we continuously sampled water depth, sub-bottom profiles and Acoustic Doppler Current Profiles (ADCP) along with flow-through sea surface temperature, salinity and in vivo fluorescence. This report summarizes physical, chemical and biological characteristics at the sea surface (Table 3, Figure 2) and at depth (Tables 4 and 5, Figure 3a) along our cruise track. A complete oceanographic survey of two submarine canyons (Hydrographer’s canyon south of Georges bank and The Gully, east of Sable Island) were completed. Bathymetry and surface currents for each seamount are available on request. Temperature, salinity and fluorescence profiles are presented (Figures 3b and 3c). Large scale hydrography is summarized by contour plots of temperature, salinity and fluorescence (Figure 4); whereas large scale current patterns are summarized by contour plots of current direction, magnitude and echo amplitude (Figure 5). In addition, the distribution and density of zooplankton at the sea surface (Table 6) and at depth (Figures 7 and 8) are presented. Sediment samples were sieved and grain size percentage of each fraction was determined (Figure 9). Additional CTD, bathymetry (CHIRP), current (ADCP) and biological data are not reported here but are available on request through Sea Education Association (SEA) and the Chief Scientist.

Teaching Confused Words

If a child confuses look-alike words, we can\u27t remediate the situation by relying on business as usual methods. Methods used previously may have contributed to the problem in the first place. Therefore, even though confused words are a subset of common sight words, we can\u27t use methodology typically used to teach children sight words; we need to use procedures especially appropriate for the situation. Fortunately, much recent attention has been paid indirectly to this problem

Minority Health Disparities: The case of the American Indians

In this presentation, Dr. Lawrence Schell talks about how globally, aboriginal populations have been in great decline, demographically and culturally. American Indians continue to be the poorest and the least healthy population within the borders of the United States. They are the most severe victims of health disparities in the US. Health disparities are preventable differences in the burden of disease, injury, violence, or opportunities to achieve optimal health that are experienced by socially disadvantaged populations (https://www.cdc.gov/healthyyouth/disparities/). Health disparities result from multiple factors, including poverty, environmental threats, inadequate access to health care, individual and behavioral factors, educational inequalities, higher rates of cancers and diabetes. There are many health risk behaviors that are more common among American Indians and Alaskan Natives also. Since 2001, in comparison to other racial/ethnic groups, they have had the largest or next largest percentage of 18 year olds without a doctor visit. In addition, some face the additional problem of an environment polluted by industries. In our study of the Akwesasne Mohawk Nation who are impacted by nearby pollution with polychlorinated biphenyls (PCBs), we saw that sexual maturation was earlier in girls in relation to their PCB level, and testosterone levels in adolescent boys were lower in relation to theirs. Thyroid hormone levels were altered also. Among adult women the risk of not ovulating was related to their level of PCBs. These are especially difficult effects considering that the survival of the culture and the people are a primary concern of the Akwesasne Mohawk people and of many American Indian and Alaskan Native groups

Transitioning from Traditional: Pollution, Diet and the Development of Children

Indigenous people in virtually all parts of the world have transitioned from a traditional way of life to incorporate western culture to some degree. The forces driving these transitions are varied although there are some common features. Today, some traditional communities are exposed to pollution from nearby industries that have been located in undeveloped areas to take advantage of natural resources, inexpensive labor, lax regulations, or other features. Avoiding sources of pollution can safeguard health, but may have untoward consequences. When exposure to pollutants is through components of the traditional diet, people must alter their diet to avoid the pollutants, and in so doing, they transition away from traditional culture. Further, avoiding local, contaminated food involves eating commercial, mass produced foods that can contribute to obesity which is a growing problem worldwide. The choice between eating uncontaminated food from stores or maintaining traditional ways including a traditional diet, is a stressful one adding to the overwhelming stress of acculturation
