NOAA's Resurrection of Program Budgeting: Déjà Vu All Over Again?

The National Oceanic and Atmospheric Administration instituted a Planning, Programming, Budgeting, and Execution System (PPBES) in 2002. As supplemented by matrix management, PPBES was appealing as an effort to rationalize the performance of an agency with an especially high degree of functional overlap among its component parts. Although PPBES has had some salutary effects, the agency's experience to date consistent with accounts of the difficulties that led to the abandonment of program budgeting by the civilian bureaucracy almost 40 years ago. As such, it speaks to the limits of performance assessment as a means of reallocating resources and responsibilities across organizational boundaries.     

The effects of NBPTS‐certified teachers on student achievement

In this study, we consider the efficacy of a relatively new and widely accepted certification system for teachers established by the National Board for Professional Teaching Standards (NBPTS). We utilize an extensive database covering the universe of teachers and students in Florida for a four‐year span to determine the relationship between NBPTS certification and the impact of teachers on student test scores from both low‐stakes and high‐stakes exams. Contrary to some previous studies, we find evidence that NBPTS certification provides a positive signal of a teacher's contribution to student achievement only in a few isolated cases. However, our results do reinforce evidence from previous research that the process of becoming NBPTS certified does not increase teacher productivity. © 2009 by the Association for Public Policy Analysis and Management.     

Leading from Below: How Sub-National Governments Influence Policy Agendas

This article takes a state's eye view of trends towards a more centralised system of governance in Australia. It argues that while globalisation strengthens the roles of national governments it also provides less noticed public policy and management opportunities for sub-national governments. The article shows how state governments in Australia can use high-level policy proposals to reinforce their continuing relevance as key members of a federal system of government. It proposes that skilful deployment of policy ideas and analyses can enable the states to sustain alternative national agendas despite hostility or lack of interest by the federal government. In conclusion, the article examines the implications for federal-state relations under the Rudd government. It suggests that the elements for productive reform agendas are present but that bringing them together will require considerable effort.     

A process for identifying social and environmental issues: a case of the US forest products manufacturing industry

• Application of an issues management approach to corporate social responsibility consists of identifying, evaluating and responding to those issues that an industry must address in order to be socially responsible. This research focussed on identifying social and environmental issues relevant to the US forest products manufacturing industry. Towards this end, 14 interviews were conducted with key‐informants drawn from non‐government organizations, government and political offices, forest products associations, a multilateral organization and an extension expert. A rich set of issues was generated covering social and environmental issues. However, such a set may contain issues that are far too radical and may be challenging for companies to pursue. Accordingly, in order to develop a doable, socially credible and concise set of issues, a Delphi technique was employed consisting of forest products management and marketing academicians from various US universities. A two‐round Delphi resulted in identification of six social and six environmental issues that the US forest products manufacturing industry must address in order to be socially responsible. This proposed two‐stage process may have special relevance for companies that are entering into new markets overseas.

Does Medicare Coverage Improve Cancer Detection and Mortality Outcomes?

Medicare is a large government health insurance program in the United States that covers about 60 million people. This paper analyzes the effects of Medicare insurance on health for a group of people in urgent need of medical care: people with cancer. We used a regression discontinuity design to assess impacts of near-universal Medicare insurance at age 65 on cancer detection and outcomes, using population-based cancer registries and vital statistics data. Our analysis focused on the three tumor sites for which screening is recommended both before and after age 65: breast, colorectal, and lung cancer. At age 65, cancer detection increased by 72 per 100,000 population among women and 33 per 100,000 population among men; cancer mortality also decreased by nine per 100,000 population for women but did not significantly change for men. In a placebo check, we found no comparable changes at age 65 in Canada. This study provides the first evidence to our knowledge that near-universal access to Medicare at age 65 is associated with improvements in population-level cancer mortality.

Maternal Acceptance as a Moderator of the Relation Between Threat to Self Appraisals and Mental Health Problems in Adolescents from Divorced Families

Appraisals about the implications of stressful events that are evaluated as involving a threat to self (negative self-evaluation, negative evaluation from others, rejection by others) have been shown to place youth at risk for the development of mental health problems. This longitudinal study tested a protective-stabilizing interactive model, in which high maternal acceptance was predicted to mitigate the prospective relation between threat to self appraisals and change in adolescents’ mental health problems six months later. Participants were 89 adolescents from divorced families ages 10–12 and residential mothers. Adolescents reported on threat to self appraisals from the most stressful event experienced in the past month. Mothers and youth reported on maternal acceptance and mental health problems. Multiple regression analyses provided support for the protective effects of maternal acceptance on adolescents’ mental health problems. Intervention implications are discussed.
