Reasons to teach music: establishing a place in the contemporary curriculum

Studies in the history of music education reveal much about the place and purpose of music in the changing curriculum. In this article, the ideas of some significant British music educators of the twentieth century are considered, in an evaluation of the apparent goals of music teaching that have been articulated over the decades. The connections between rationale and practice are discussed, with published ideas placed alongside the views of contemporary teachers in a small-scale questionnaire survey. The conclusion is proposed that school music, as a small part of the child's musical identity, must be modest in its intentions but ambitious in its provision

Smoking: taxing health and Social Security

Cigarette smoking is costly in terms of not only its effects on smokers' health but also the direct and indirect financial costs it imposes on smokers and their families. For instance, premature death caused by smoking may redistribute Social Security income in unexpected ways that affect behavior and reduce the economic well-being of smokers and their dependents. ; This article examines the effects of smoking-attributable mortality on the net marginal Social Security tax rate (NMSSTR)—the difference between the statutory payroll tax rate and the present value of future benefits to which a covered worker is entitled. ; The analysis shows that smokers, as a result of shorter life expectancies, incur a higher NMSSTR than nonsmokers. This higher tax rate could have implications for both labor supply behavior and the Social Security System's funding. ; The authors note that smoking status should be considered in assessing Social Security legislative proposals designed to reduce system inequities or promote social adequacy—in particular, amendments designed to reduce poverty among young widows and widowers. Failure to take smoking status into account may unintentionally promote behavior that is detrimental to health.Social security

Smoking: taxing health and Social Security

While the health risks associated with smoking are well known, the impact on income distributions is not. This paper extends the literature by examining the distributional effects of a behavioral choice, in this case smoking, on net marginal Social Security tax rates (NMSSTR). The results show that smokers, as a result of shorter life expectancies, incur a higher NMSSTR than nonsmokers. In addition, as low-earnings workers have a higher smoking prevalence than high-earnings workers, smoking works to widen the income distribution. This higher tax rate could have implications for both labor supply behavior and Social Security system funding.

The quality of preventive and diagnostic medical care: why do southern states underperform?

As the cost of health care increases rapidly, the health care industry has turned its attention to methods of cost containment. However, concern exists that the drive to contain costs could lead to compromises in the quality of medical care. One practice that may slow the growth rate of health care expenditures and improve morbidity and mortality rates is the widespread use of preventive and diagnostic services. ; Using data compiled by the Centers for Medicare and Medicaid Services, this article evaluates the quality of care received by Medicare beneficiaries in each state. The authors examine states’ use of preventive services (influenza and pneumococcal immunizations) and diagnostic services (mammograms and diabetes screening tests) among Medicare beneficiaries. ; The analysis points out regional differences in preventive and diagnostic care across the United States. The West has higher levels of preventive care while the Northeast has higher scores for diagnostic care. But the South had the lowest average score for quality of care in both categories. The authors attribute differences among states’ levels of preventive and diagnostic care to their socioeconomic and demographic characteristics, noting in particular that the percentage of a state’s Medicare population that is black is inversely related to the quality of medical care. ; A better understanding of the causes behind racial disparities in the quality of medical care, the authors conclude, will promote the delivery of the highest quality of care to all Medicare beneficiaries and slow the growth rate of health care costs.

Does disability explain state-level differences in the quality of Medicare beneficiary hospital inpatient care?

Almost 20 percent of the total U.S. population and 42 percent of the population over the age of sixty-six are disabled. Research has shown that the presence of a disability can crowd out treatment for medical conditions not necessarily related to the disability and that states that are disproportionately African-American have a lower quality of hospital care. This paper uses quality of care data from the Centers for Medicare and Medicaid Services (CMS) to determine whether disability also explains state-level differences in quality of hospital care. The quality of Medicare beneficiary hospital care was measured using process measures for several medical conditions, including acute myocardial infarction, heart failure, stroke, and pneumonia, that are the leading causes of mortality. We use nonlinear least squares to assess the association between Medicare beneficiary quality of care and state- and medical system–level characteristics. The result for the key variable of interest—disability—reveals that a 1 percent increase in a state's disability rate leads to a 1 percentage point reduction in the score of the state's quality of hospital care. Without explicitly incorporating strategies to eliminate disparities in care incurred by people with disabilities, CMS may not adequately promote the goal of delivering the highest quality of care to all Medicare beneficiaries.

Cigarette smoking and food insecurity among low-income families in the United States, 2001

The goal of this research is to quantify the association between food insecurity and smoking among low-income families. This analysis is a retrospective study using data from the 2001 Panel Study of Income Dynamics, a longitudinal study of a representative sample of U.S. men, women, and children and the family units in which they reside. Family income is linked with U.S. poverty thresholds to identify 2,099 families living near or below 200 percent of the federal poverty level. Food insecurity (that is, having insufficient funds to purchase enough food to maintain an active and healthy lifestyle) is calculated from the eighteen core items in the food security module of the U.S. Department of Agriculture. The results indicate that smoking prevalence is higher among low-income families who are food insecure compared to low-income families who are food secure (43.6 percent versus 31.9 percent). Multivariate analysis reveals that smoking is associated with an increase in food insecurity of approximately 6 percentage points. Given our finding that families near the federal poverty level spend a large share of their income on cigarettes, perhaps it would be prudent for food assistance and tobacco control programs to work together to help low-income people quit smoking.

Denotational semantics with nominal scott domains

When defining computations over syntax as data, one often runs into tedious issues concerning α -equivalence and semantically correct manipulations of binding constructs. Here we study a semantic framework in which these issues can be dealt with automatically by the programming language. We take the user-friendly “nominal” approach in which bound objects are named. In particular, we develop a version of Scott domains within nominal sets and define two programming languages whose denotational semantics are based on those domains. The first language, λν -PCF, is an extension of Plotkin’s PCF with names that can be swapped, tested for equality and locally scoped; although simple, it already exposes most of the semantic subtleties of our approach. The second language, PNA, extends the first with name abstraction and concretion so that it can be used for metaprogramming over syntax with binders. For both languages, we prove a full abstraction result for nominal Scott domains analogous to Plotkin’s classic result about PCF and conventional Scott domains: two program phrases have the same observable operational behaviour in all contexts if and only if they denote equal elements of the nominal Scott domain model. This is the first full abstraction result we know of for languages combining higher-order functions with some form of locally scoped names which uses a domain theory based on ordinary extensional functions, rather than using the more intensional approach of game semantics. To obtain full abstraction, we need to add two functionals, one for existential quantification over names and one for “definite description” over names. Only adding one of them is not enough, as we give counter-examples to full abstraction in both cases.This work is supported by a Gates Cambridge Scholarship and the ERC Advanced Grant Events, Causality and Symmetry (ECSYM)This version is the author accepted manuscript.

Constrained Dynamics of Universally Coupled Massive Spin 2-spin 0 Gravities

The 2-parameter family of massive variants of Einstein's gravity (on a Minkowski background) found by Ogievetsky and Polubarinov by excluding lower spins can also be derived using universal coupling. A Dirac-Bergmann constrained dynamics analysis seems not to have been presented for these theories, the Freund-Maheshwari-Schonberg special case, or any other massive gravity beyond the linear level treated by Marzban, Whiting and van Dam. Here the Dirac-Bergmann apparatus is applied to these theories. A few remarks are made on the question of positive energy. Being bimetric, massive gravities have a causality puzzle, but it appears soluble by the introduction and judicious use of gauge freedom.Comment: 6 pages; Talk given at QG05, Cala Gonone (Italy), September 200
