Research Findings

This paper scrutinized hydraulic fracturing applications mainly in the United States with regard to both groundwater and surface water contamination with the purpose of bringing forth objective analysis of research findings. Results from previous studies are often unconvincing due to the incomplete database of chemical additives; after and before well-founded water samples to define the change in parameters; and specific sources of water pollution in a particular region. Nonetheless, there is a superior chance of both surface and groundwater contamination induced by improper and less monitored wastewater disposal and management practices. This report has documented systematic evidence for total dissolved solids, salinity, and methane contamination regarding drinking water correlated with hydraulic fracturing. Methane concentrations were found on an average rate of 19.2 mg/L, which is 17 times higher than the acceptance rate and the maximum value was recorded as 64.2 mg/L near the active hydraulic fracturing drilling and extraction zones than that of the nonactive sites (1.1 mg/L). The concentration of total dissolved solids (350 g/L) was characterized as a voluminous amount of saline wastewater, which was quite unexpectedly high. The paper concludes with plausible solutions that should be implemented to avoid further contamination.

Induced Seismic Activity

High-volume hydraulic fracturing combined with horizontal drilling has “revolutionized” the United States’ oil and gas industry by allowing extraction of previously inaccessible oil and gas trapped in shale rock [1]. Although the United States has extracted shale gas in different states for several decades, the United Kingdom is in the early stages of developing its domestic shale gas resources, in the hopes of replicating the United States’ commercial success with the technologies [2, 3]. However, the extraction of shale gas using hydraulic fracturing and horizontal drilling poses potential risks to the environment and natural resources, human health, and communities and local livelihoods. Risks include contamination of water resources, air pollution, and induced seismic activity near shale gas operation sites. This paper examines the regulation of potential induced seismic activity in Oklahoma, USA, and Lancashire, UK, and concludes with recommendations for strengthening these protections.

Research Findings

AbstractIn recent years there has been an increasing emphasis on achieving convergence in disaster research, policy, and programs to reduce disaster losses and enhance social well-being. However, there remain considerable gaps in understanding “how do we actually do convergence?” In this article, we present three case studies from across geographies—New South Wales in Australia, and North Carolina and Oregon in the United States; and sectors of work—community, environmental, and urban resilience, to critically examine what convergence entails and how it can enable diverse disciplines, people, and institutions to reduce vulnerability to systemic risks in the twenty-first century. We identify key successes, challenges, and barriers to convergence. We build on current discussions around the need for convergence research to be problem-focused and solutions-based, by also considering the need to approach convergence as ethic, method, and outcome. We reflect on how convergence can be approached as an ethic that motivates a higher order alignment on “why” we come together; as a method that foregrounds “how” we come together in inclusive ways; and as an outcome that highlights “what” must be done to successfully translate research findings into the policy and public domains.

Study Design: Retrospective case study. Objective: To evaluate the trends and demographics of recombinant human bone morphogenetic protein 2 (rhBMP2) utilization in single-level anterior lumbar interbody fusion (ALIF) in the United States. Methods: Patients who underwent single-level ALIF from 2005 to 2011 were identified by searching ICD-9 diagnosis and procedure codes in the PearlDiver Patient Records Database (PearlDiver Technologies, Fort Wayne, IN), a national database of orthopedic insurance records. The year of procedure, age, gender, and region of the United States were analyzed for each patient. Results: A total of 921 patients were identified who underwent a single-level ALIF in this study. The average rate of single-level ALIF with rhBMP2 utilization increased (35%-48%) from 2005 to 2009, but sharply decreased to 16.7% in 2010 and 15.0% in 2011. The overall incidence of single-level ALIF without rhBMP2 (0.20 cases per 100 000 patients) was more than twice of the incidence of single-level ALIF with rhBMP2 (0.09 cases per 100 000 patients). The average rate of single-level ALIF with rhBMP2 utilization is highest in West (41.4%), followed by Midwest (33.3%), South (26.5%) and Northeast (22.2%). The highest incidence of single-level ALIF with rhBMP2 was observed in the group aged less than 65 years (compared with any other age groups, P < .001), with an incidence of 0.21 per 100 000 patients. Conclusions: The incidence of rhBMP2 utilization in single-level ALIF increased from 2006 to 2009, but decreased in 2010 and 2011. The Northeast region had the lowest incidence of rhBMP2 utilization. The group aged less than 65 years trended to have the higher incidence of single-level ALIF with rhBMP2 utilization.

This article explores collaborative capital budgeting in U.S. local governments. To date, the capital budgeting literature has focused on practices within individual governments. This leaves a gap in our understanding because a large portion of capital planning, acquisition, and maintenance occurs through collaboration between two or more local governments. Drawing on the capital budgeting and collaborative public management literature, and on illustrative cases of collaborative capital budgeting in the United States, an inductive approach is used to: (1) identify and categorize the different objectives that motivate local officials to pursue collaborative agreements, (2) examine common patterns in the types of assets involved in collaboration, and (3) discover common institutional arrangements in collaboration agreements. The research findings demonstrate significant heterogeneity in the objectives, patterns, and institutions of collaborative capital budgeting.

This article reports on empirical research findings from a case study of teacher education in Finland and the United States. A sociological perspective was deployed for investigating how the concept of sustainability was addressed in two teacher education programs. One of the programs was located in Finland and the other in the US. The study was carried out in 2015 and 2016. Seventeen semi-structured, open-ended, audio-recorded interviews form the core of the research materials. A thematic analysis of interviews was conducted for identifying articulations related to sustainability in subject-matter specialized teacher preparation. Findings from this study contribute to research on teacher preparation. Notably, by articulating how context-specific culture and social norms contribute to local models of teacher education. Findings from this study indicate that teacher training practices in Finland have encouraged students to articulate sustainability in relation to critical thinking, whereas in the US, sustainability has been articulated in relation to social justice. The key point supported by the evidence is that sustainability was by teachers and teacher educators conceptualized as being about the popularization of knowledge about ecology and biodiversity. The kind of communication that was by teachers and teacher educators described as effective for popularizing knowledge about scientific phenomena were forms of teaching that expanded on content-specific knowledge by connecting it to ethical and civic frameworks of the societies in which students live.

Housing Segregation

Recent work in urban geography and political ecology has explored the roots of housing segregation in the United States within governmental polices and racial prejudice within the real estate sector. Additional research has demonstrated how coastal management practices has largely benefited wealthy, white communities. In this paper, I bring together insights from these two strands of research to demonstrate how both coastal management and governmental housing policies combined to shape racial inequalities within and around Asbury Park, New Jersey. By focusing on the period between 1945 and 1970, I show how local, state, and federal actors repeatedly prioritized improving and protecting the beachfront areas of the northern New Jersey shore while promising to eventually address the housing and economic needs of the predominately Black ‘West Side’ neighbourhood of Asbury Park. This paper demonstrates that not only did governmental spending on coastal management largely benefit white suburban homeowners but also came at the expense of promised spending within Black neighbourhoods. The case study has implications for other coastal regions in the United States in which housing segregation persists. As climate change and sea level rise unfold, the history of racial discrimination in coastal development raises important considerations for efforts to address emerging hazards and risks.

Effective Integration

This chapter chronicles the planning and classroom management practices of the first-year implementation of a 1:1 iPad initiative in a suburban, co-educational, independent, PreK-4th grade elementary school in the United States that was examined through a mixed methods QUAL ? QUAN case study. Findings demonstrate that the school's administrators and teachers engaged in pre-planning activities prior to the implementation of the iPad initiative, teachers viewed the iPads as tools in the planning process (iPads were not perceived as the content or subject to be taught/learned), and teachers flexibly employed different classroom management techniques and rules as they learned to integrate iPads in their classrooms. Additionally, the findings reveal the need for continuous formal and informal professional development that offers teachers multiple and varied opportunities to share their planning and classroom management practices, build their confidence and expertise in effective integration of iPads, and learn with and from one another.
