Introduction to mathematical physics

A comprehensive survey of all the mathematical methods that should be available to graduate students in physics. In addition to the usual topics of analysis, such as infinite series, functions of a complex variable and some differential equations as well as linear vector spaces, this book includes a more extensive discussion of group theory than can be found in other current textbooks. The main feature of this textbook is its extensive treatment of geometrical methods as applied to physics. With its introduction of differentiable manifolds and a discussion of vectors and forms on such manifolds as part of a first-year graduate course in mathematical methods, the text allows students to grasp at an early stage the contemporary literature on dynamical systems, solitons and related topological solutions to field equations, gauge theories, gravitational theory, and even string theor

Behavioral risk profiles of homeschooled adolescents in the United States: a nationally representative examination of substance use related outcomes

BACKGROUND: The homeschool population continues to grow in size and now accounts for 3.4% of all students in the United States. OBJECTIVE: Given the heterogeneous nature of the population, this study examines the relationship between different types of homeschoolers and a number of substance use related outcomes. METHODS: To conduct this study, we used pooled data (2002–2013) from the National Survey on Drug Use and Health (NSDUH). Respondents aged 12–17 who reported they had been homeschooled at any time during the previous 12 months were classified as homeschoolers (N = 1,321). Latent profile analysis (LPA) was conducted to identify latent subgroups of homeschoolers and multinomial regression was executed to assess the relationship between the subgroups and perceived substance use risk, availability, and past 12-month use. RESULTS: The LPA yielded four subgroups, which were summarized as (1) highly religious and engaged, (2) limited parental monitoring, (3) high parental warmth and support, and (4) secular permissive. Of these, the highly religious and engaged subgroup was the least likely to report using substances. CONCLUSION: The results underscore the variation that exists among homeschoolers and the importance of examining the relationship between different types of homeschoolers and outcomes of interest

India: Domestic Issues, Strategic Dynamics, and U.S. Relations

[Excerpt] President Barack Obama’s Administration has sought to build upon the deepened U.S. engagement with India begun by President Bill Clinton in 2000 and expanded upon during much of the past decade under President G.W. Bush. This “U.S.-India 3.0” diplomacy was most recently on display in July 2011, when the second U.S.-India Strategic Dialogue session saw a large delegation of senior U.S. officials visit New Delhi to discuss a broad range of global and bilateral issues. Many analysts view the U.S.-India relationship as being among the world’s most important in coming decades and see potentially large benefits to be accrued through engagement on many convergent interests. Bilateral initiatives are underway in all areas, although independent analysts in both countries worry that the partnership has lost momentum in recent years. Outstanding areas of bilateral friction include obstacles to bilateral trade and investment, including in the high-technology sector; outsourcing; the status of conflict in Afghanistan; climate change; and stalled efforts to initiate civil nuclear cooperation. India is the world’s most populous democracy and remains firmly committed to representative government and rule of law. Its left-leaning Congress Party-led ruling national coalition has been in power for more than seven years under the leadership of Prime Minister Manmohan Singh, an Oxford-trained economist. New Delhi’s engagement with regional and other states is extensive and reflects its rising geopolitical status. The national economy has been growing rapidly—India’s is projected to be the world’s third-largest economy in the foreseeable future—yet poor infrastructure, booming energy demand, and restrictive trade and investment practices are seen to hamper full economic potential. Despite the growth of a large urban middle-class, India’s remains a largely rural and agriculture-based society, and is home to some 500-600 million people living in poverty. This report will be updated periodically

Trends and correlates of marijuana use among late middle-aged and older adults in the United States, 2002–2014

BACKGROUND: Recent trend studies suggest that marijuana use is on the rise among the general population of adults ages 18 and older in the United States. However, little is known about the trends in marijuana use and marijuana-specific risk/protective factors among American adults during the latter part of adulthood. METHOD: Findings are based on repeated, cross-sectional data collected from late middle-aged (ages 50–64) and older adults (ages 65 and older) surveyed as part of the National Survey on Drug Use and Health between 2002 and 2014. RESULTS: The prevalence of past-year marijuana use among late middle-aged adults increased significantly from a low of 2.95% in 2003 to a high of 9.08% in 2014. Similarly, the prevalence of marijuana use increased significantly among older adults from a low of 0.15% in 2003 to a high of 2.04% in 2014. Notably, the upward trends in marijuana use remained significant even when accounting for sociodemographic, substance use, behavioral, and health-related factors. We also found that decreases in marijuana-specific protective factors were associated with the observed trend changes in marijuana use among late middle-aged and older adults, and observed a weakening of the association between late-middle aged marijuana use and risk propensity, other illicit drug use, and criminal justice system involvement over the course of the study. CONCLUSIONS: Findings from the present study provide robust evidence indicating that marijuana use among older Americans has increased markedly in recent years, with the most evident changes observed between 2008 and 2014

Section 1983 Civil Liability Against Prison Officials and Dentists for Delaying Dental Care

Many prisoners enter correctional facilities in the United States with little history of good dental hygiene and even less history of access to dentists. Thus, the incarceration experience presents opportunities for inmates to receive quality dental care, often for the first time. Dental care delivered by correctional dentists is complicated, however, by the array of serious dental conditions and difficult to treat dental problems in clinical settings. These conditions exist within a legal environment that mandates adequate dental care be provided to prisoners by the state. This article examines prisoners’ Section 1983 lawsuits, claiming that delays in the delivery of dental care violate inmates’ federally guaranteed rights. The analysis focuses on what the U.S. Circuit Courts of Appeals have required of correctional officials and dentists in the form of dental care, concluding with nine best practices for correctional dental practitioners to follow to avoid Section 1983 liability
