Photon correlations in positron annihilation

The two-photon positron annihilation density matrix is found to separate into a diagonal center of energy factor implying maximally entangled momenta, and a relative factor describing decay. For unknown positron injection time, the distribution of the difference in photon arrival times is a double exponential at the para-Ps decay rate, consistent with experiment (V. D. Irby, Meas. Sci. Technol. 15, 1799 (2004)).Comment: Accepted for publication in Phys. Rev.

MODs: collaboration and play in design

Located in Richmond, Virginia, MO Design is a small design/build company founded by Molly O’Saben. Ms. O’Saben received her bachelor’s degree in Craft & Material Studies and her master’s in Interior Environments from Virginia Commonwealth University. MO Design was founded in 2010 with a team of fellow alumni from VCU. We make objects that inspire inventiveness. Our reconfigurable components offer our clients the unique ability to adapt their environments to life’s ever-changing needs. We make MODs: Make your Own Designs. Our products are for people who appreciate efficient spaces, are open to exploring possibilities, and like to play. Just as Legos have uniform connections providing a myriad of options for building, our MODs offer the same versatility in a serious adult form. Use our building blocks to make a table, chair, or custom wall unit. When your needs change, dismantle your chair and rebuild it into a bookcase. We make objects that challenge the client to investigate. With exploration of their needs and implementation of their design comes a sense of accomplishment. We want to create this feeling of pride through working hard at play. MODs serve the needs of young and old, differing personalities, multiple demographics and help keep the world green with each reconfiguration. OUR MISSION: to bring the pride of making back to the individual. We design, build, and distribute our products. Our company designs components that offer versatility to our customers. MODs are block-like pieces that joint together using tradition mortise and tenon construction. The components we make can be reconfigured like puzzles, providing hours of entertainment for all ages. For our more conservative customers we make MOD PODs: a collection of MODs packaged and sold with assembly instructions to make a specific piece. MO Design also offers MOD Design Services. We can build a custom office, living room, or children’s bedroom with our products based on your unique specifications. We design to produce options, reduce waste, and create fun in the process. Our clients purchase products based on quality, versatility, and sustainability. Our products challenge how we see furniture – from monolithic, singular objects to dynamic tools for living. Small spaces need flexibility and the proper pieces are essential to an organized environment. Our products offer the: • opportunity for individuals to create custom designs. • ability to customize products without needing expensive, dangerous tools. • potential for growth with new designs that continue to connect to original parts. • enhancement of human needs, both physical and emotional. • excitement of exploration, collaboration, and play. • versatility to compliment any lifestyle, from highlighted piece to a closet storage system. • manageability of a product that can be moved and manipulated by a single person.• a challenge to our current product cycles: buy, use, and discard. So, lets play with MODs

Physicians’ Experiences and Opinions Regarding Strategies to Improve Care for Minority Patients

Objective: To assess the views and experiences of a select group of physicians interested in minority health issues regarding promising strategies to improve minority care. Methods: Physicians were asked to respond to a 17-item survey assessing the level of agreement, frequency of implementation of and interest in learning more about 7 promising strategies for alleviating disparities. Results: Most physicians (75-95%) agreed that the 7 proposed strategies could be useful to improve the quality of care provided to minority patients, but only 40-66% of physicians had implemented the strategies sometimes or often in their practices. Between 22 and 29% of physicians were interested in learning more about 6 of the 7 strategies, preferably by CME, seminars and newsletters. Conclusion: Physicians concerned with minority health issues agree that commonly suggested strategies for eliminating racial and ethnic disparities in health care could be useful, but have difficulty implementing such approaches

Mathematics Anxiety and Pre-Service Teachers

Mathematics anxiety has been a topic of interest since the 1950s. It has been shown that apprehensive elementary mathematics teachers unintentionally transfer anxiety to students in their classroom. In this study we assessed the change in 34 pre-service teacher\u27s anxiety, self-efficacy and perception of ability during and after a content-specific mathematics course. This study used a mixed method approach for analyze data. The results suggests that anxiety decreased over the semester and perception of ability and self-efficacy increased. The levels of confidence with the material were recorded before and after three exams in the course. The pre-service teacher\u27s change in levels of confidence following the exams rose from an average of 2.98 to a 4.30 level out of 5. We chose three students from the participants who gave different pictures of their feelings towards mathematics to investigate in detail

Demographic Trends in Boston: Some Implications for Municipal Services

The City of Boston is gaining in population during the 1980s, after several decades of loss. During the current decade and beyond, population trends will bring increases in the number of children, adults between the ages of twenty-five and forty-four, and those aged seventy-five and over, along with declines among the older teenagers and college-age population, the more mature adults, and the younger elderly. A recent analysis of the income distribution indicates that while there were more well-to-do residents in Boston in 1985 than there were in 1980, there were also more poor and near poor. Average family income has declined in real terms during this five-year period, whereas it has increased for unrelated individuals. Minorities, children, and the elderly are more likely to be living in poverty than other segments of the population. Related to this, single-parent families and those who live alone contribute the largest share of families and unrelated individuals in poverty. The implications of these trends for two areas of municipal services — health care and education — are examined, because these services are especially responsive to demographic pressures. Data on health insurance coverage cite the need of the poor for health services. This need might be met by rebuilding Boston City Hospital or by alternative health insurance coverage plans. Among Boston\u27s public school children, a high proportion lack strong economic and familial support systems. The schools need to assess the extent to which, within the constraints of a limited budget, they can serve the very needy and those who seek a high-quality education
