Abstract Embankment dam failures are concerning to many people in the society today, including dam engineers, federal, state, and local officials. The effects of dam failure may cause more harm than good; leading to the losses of lives, properties being damage, economic and environmental downfall. Embankment dam breaching is a complex process between hydraulics and soil erosion processes; until today it still requires more researches to be done. Many factors involved in embankment breaching such as cohesiveness of embankment material, compactness of the embankment soil material, height of the dam and slope of the dam. Through the help of simulation techniques such as computational fluid dynamics, it is possible to understand the behaviour of embankment breaching processes. In this research, modelling of embankment breaching with the aid of FLOW-3D allow us to open doors to plenty of experiments to breaching in the near future. This research focuses in analysing and comparing hydrodynamic parameters; breach outflow hydrograph, peak outflow rate Qp and failure time iy, and geometric parameters; breach depth Hb , and top breach width Bt , of the modelling breached embankment for different sediment diameter and inflow rates. Moreover, the research also investigates the velocity magnitude and breach width during the embankment breaching process.

This paper presents strategies for increasing the effectiveness and efficiency of the school-based speech-language pathologist. Various time management strategies are adapted and outlined for three major areas of concern: using time, organizing the work area, and managing paper work. It is suggested that the use of such methods will aid the speech-language pathologist in coping with federal, state, and local regulations while continuing to provide quality therapeutic services.

For many families across Pennsylvania, child care is an ever-present concern. Since the 1970s, when Richard Nixon vetoed a national childcare program, child care has received little time in the policy spotlight. Instead, funding for child care in the United States now comes from a mixture of federal, state, and local programs that do not help all families. This article explores childcare options available to families in the state of Pennsylvania and highlights gaps in the current system. Specifically, we examine the state of child care available to families in the Commonwealth in terms of quality, accessibility, flexibility, and affordability. We also incorporate survey data from a nonrepresentative sample of registered Pennsylvania voters conducted by the Pennsylvania Center for Women and Politics. As these results support the need for improvements in the current childcare system, we discuss recommendations for the future.

There are serious gaps in our knowledge and understanding of how public policy at the federal, state, and local levels affects the work of a wide array of nonprofit organizations. On October 4th and 5th, 2010, the Association for Research on Nonprofit Organizations and Voluntary Organizations (ARNOVA), with the support and encouragement of the Bill and Melinda Gates, Kresge and C.S. Mott foundations, convened a group of thirty nonprofit scholars and leaders to explore what we know about the impact of public policy on the nonprofit sector. The conference focused on how public policy helps or harms the ability of nonprofit organizations, particularly but not exclusively public charities, to fulfill their missions.

Patient-centered care is at the nexus of several overlapping institutional reforms to improve health care system performance. However, we know little regarding Medicaid patients’ experience with their doctors along several key dimensions of patient-centered care, and how their experience compares with Medicare and privately insured patients. We studied 4 outcomes using the 2017 National Health Interview Survey: patient–provider concordance on racial/sexual/cultural identity, respectful provider attitude, solicitation of patient opinion/beliefs during the care encounter, and patient-centered communication (PCC). The primary independent variable was Medicaid enrollee status. We dichotomized responses and ran multivariate logistic regressions for each type of care experience outcome, controlling for sociodemographic factors, health care access, and health care utilization of respondents. Compared to Medicare and privately insured enrollees, Medicaid enrollees reported much lower odds of seeing providers who treated them with respect (OR = 1.91, P < .001; OR = 1.62, P < .01) and who offered PCC (OR = 1.35, P < .05; OR = 1.35, P < .01), but similar odds of seeing concordant providers (OR = 0.78, P = .96; OR = 0.96, P = .72). Importantly, Medicaid enrollees reported higher odds of seeing providers who solicited their opinion/beliefs/preferences than their Medicare or privately insured counterparts (OR = 0.82, P < .05; OR = 0.87 P < .10). Medicaid enrollees report less patient-centered experiences in some important facets of their provider interaction than their Medicare or privately insured counterparts. Federal, state, and local policies and practices directed at improving these facets of patient–provider interaction are needed and should be aimed squarely at Medicaid providers, especially those working in geographic areas and settings with a disproportionate number of racial, gender, cultural, and linguistic minorities.

Instead of asking whether money matters, this paper questions whose money matters in public education. Previous literature on education funding uses an aggregate expenditure per pupil to measure the relationship between education funding and academic performance. Federalism creates mainly three levels of funding sources: federal, state, and local governments. Examining New York State school districts, most equitably funded across school districts among the 50 states, this paper shows that neither federal nor state funds are positively correlated with graduation rates. Only local revenues for school districts indicate a strong positive impact. Parents’ money matters. This finding contributes to a contentious discourse on education funding policy in the governments, courts, and academia with respect to education funding and inequality in American public schools.

Federal and state enforcement authorities have increasingly intervened on the criminal overprescribing of opioids. However, little is known about the health effects these enforcement actions have on patients experiencing disrupted access to prescription opioids or medication-assisted treatment/medication for opioid use disorder. Simultaneously, opioid death rates have increased. In response, the Maryland Department of Health (MDH) has worked to coordinate mitigation strategies with enforcement partners (defined as any federal, state, or local enforcement authority or other governmental investigative authority). One strategy is a standardized protocol to implement emergency response functions, including rapidly identifying health hazards with real-time data access, deploying resources locally, and providing credible messages to partners and the public. From January 2018 through October 2019, MDH used the protocol in response to 12 enforcement actions targeting 34 medical professionals. A total of 9624 patients received Schedule II-V controlled substance prescriptions from affected prescribers under investigation in the 6 months before the respective enforcement action; 9270 (96%) patients were residents of Maryland. Preliminary data indicate fatal overdose events and potential loss of follow-up care among the patient population experiencing disrupted health care as a result of an enforcement action. The success of the strategy hinged on endorsement by leadership; the establishment of federal, state, and local roles and responsibilities; and data sharing. MDH’s approach, data sources, and lessons learned may support health departments across the country that are interested in conducting similar activities on the front lines of the opioid crisis.

Policy related to homelessness varies across federal, state, and local levels influencing access to health and social services among persons experiencing homelessness. With a diversity of community stakeholders comes a diversity of ideas about which health and social services to provide and prioritize. Despite the unique insights PEH are able to offer on their own situations, their voices often remain excluded from research and policy. The aim of the current study was to identify the basic needs and health and social service priorities of PEH, to incorporate these voices into policy decisions and prioritization. Fifteen participants age 18 and older who had any experience of homelessness in Salt Lake Countyparticipated in in-depth qualitative interviews between February and March 2020. Open-ended questions enabled the interviews to naturally progress and focus on what was most relevant to participants and their experience. Data were categorized into the services and supports identified as the most needed by PEH and to help lift people out of homelessness: 1) Housing and shelter, 2) Income and employment, 3) Transportation, 4) Food, 5) Physical and mental health services, and 6) Social support. We describe the needs, challenges, and solutions as identified and narrated by study participants. Findings offer critical insight into how the homelessness crisis should be approached by policymakers as the ways in which PEH understand and utilize the system of available resources and supports must align with their abilities and realities. Without these in-depth discussions with PEH about how they understand and meet their basic needs, there will be ongoing gaps in service delivery and mismatches in the attempts made to serve this population.

The Partnership for Reviving Routine Immunization in Northern Nigeria - Maternal, Newborn and Child Health initiative supports efforts by the government of Nigeria to bridge primary health care (PHC) policies and services at three levels of government: federal, state and local. The paper suggests that understandings informed by complexity theory and complex adaptive systems have been helpful in shaping policy and programme design across these levels. To illustrate this, three initiatives are explored: <em>Bringing PHC under one roof</em>, enhancing access to funding provided by the Global Alliance for Vaccines and Immunization, and strengthening the midwives service scheme. These initiatives have demonstrated how concepts and experience developed at subnational level can influence national policy and practice, and how work at subnational levels can add value to nationally conceived and nationally driven plans for PHC.
