A production modeling approach to the assessment of the horseshoe crab (Limulus polyphemus) population in Delaware Bay

Horseshoe crab (Limulus polyphemus) is harvested commercially, used by the biomedical industry, and provides food for migrating shorebirds, particularly in Delaware Bay. Recently, decreasing crab population trends in this region have raised concerns that the stock may be insufficient to fulfill the needs of these diverse user groups. To assess the Delaware Bay horseshoe crab population, we used surplus production models (programmed in ASPIC), which incorporated data from fishery-independent surveys, fishery-dependent catch-per-unit-of-effort data, and regional harvest. Results showed a depleted population (B2003/=0.03−0.71) BMSY and high relative fishing mortality /FMSY=0.9−9.5). Future harvest (F2002strategies for a 15-year period were evaluated by using population projections with ASPICP software. Under 2003 harvest levels (1356 t), population recovery to BMSY would take at least four years, and four of the seven models predicted that the population would not reach BMSY within the 15year period. Production models for horseshoe crab assessment provided management benchmarks for a species with limited data and no prior stock assessmen

Framing audience prefigurations of The Hobbit: An Unexpected Journey: The roles of fandom, politics and idealised intertexts

Audiences for blockbuster event-film sequels and adaptations often formulate highly developed expectations, motivations, understandings and opinions well before the films are released. A range of intertextual and paratextual influences inform these audience prefigurations, and are believed to frame subsequent audience engagement and response. In our study of prefigurative engagements with Peter Jackson’s 2012 film, The Hobbit: An Unexpected Journey, we used Q methodology to identify five distinct subjective orientations within the film’s global audience. As this paper illustrates, each group privileges a different set of extratextual referents – notably J.R.R. Tolkien’s original novels, Peter Jackson’s The Lord of The Rings film trilogy, highly localised political debates relating to the film’s production, and the previous associations of the film’s various stars. These interpretive frames, we suggest, competed for ascendancy within public and private discourse in the lead up to The Hobbit’s international debut, effectively fragmenting and indeed polarising the film’s prospective global audience

You\u27ve Got a Friend in Me: Effectiveness of Social Skills Interventions for Children with ADHD

Children diagnosed with ADHD present with the core symptoms of inattention and hyperactivity/impulsivity, which lead to challenges with school based activities, including peer interactions, academics, and extracurricular activities (McClelland, Morrison, & Holmes, 2000; Hoza, 2007). Current research identifies social skills interventions as a potential strategy for occupational therapists (OTs) to address these participation challenges of children with ADHD, however there is a multitude of interventions that fall under this umbrella. The variety of social skills interventions allows for flexibility and diversity in implementation, but poses the challenge of choosing the most effective intervention. This choice should be informed by evidence-based practice, ensuring the viability of the profession and moving it towards the Centennial Vision (Clark, 2010). To understand the effectiveness of the available social skills interventions for children with ADHD, a systematic review was conducted. The purpose of this session is to present the results of an evidence-based review on the effectiveness of social skills interventions to improve school participation for children with ADHD and discuss implications for clinical practice. The authors searched 6 data bases, resulting in analysis of 12 articles to investigate effectiveness of social skills interventions for children with ADHD. The systematic review process is presented, including the clinical question, inclusion/exclusion criteria, and search terms. The authors outline emerging themes within the research. The authors found moderate support for effectiveness of interventions implemented in physical settings where children are naturally engaging in activities. There is also promising research supporting the use of a combined cognitive behavioral and play-based approach. Evidence did not support the use of a solely cognitive behavioral approach These results suggest that social skills interventions have potential as an effective technique to improve school participation in children with ADHD. Social skills interventions are often used in conjunction with other therapies, and provide a supplement to academics-focused therapy. To advance understanding of social skills interventions, continued research is needed to determine the effectiveness of social skills interventions, discern the most appropriate form of social skills intervention for each student, and solidify OT’s role in social participation intervention.

THE DECISION TO DECENTRALIZE GOOD PROVISION IN THE UNITED STATES: A STUDY IN CLEAN ENERGY POLICY

Normative economic theory provides justification for at least partially centralized renewable energy provision due to the large, positive externalities associated with renewable energy production. However, the United States is one of the few countries without centralized renewable energy policy. Instead, the federal government actively chooses decentralized renewable energy provision by using fiscal transfers to support subnational renewable energy development. This dissertation explores why U.S. legislators choose decentralized renewable energy provision by asking two primary questions. First, what is the motivation for using federal fiscal transfers for decentralized renewable energy output considering what we know about positive spillovers and market failure associated with decentralized renewable energy production? Second, do fiscal transfers for decentralized renewable energy provision increase renewable energy production at the local level? The theoretical model proposed in Chapter Four posits why policymakers choose decentralized renewable energy provision. The chapter argues that the current political price associated with a specific policy issue affects legislators’ choices regarding good provision. I hypothesize that when the political price associated with vying for centralized good provision is high, legislators are incentivized to choose decentralized good provision. Chapter Five applies this theory to empirically evaluate the choice to decentralize renewable energy provision. The chapter examines whether the current political price of renewable energy policy affects the likelihood of a legislator proposing decentralized funding for renewable energy provision. I hypothesize that legislators will propose funding to support decentralized renewable energy development when the political price associated with renewable energy policies is high at a given time. The results show that when the political price of renewable energy policy is low, a policymaker is less likely to use grants to support renewable energy projects, finding support for the hypothesis. Chapter Six empirically evaluates the effectiveness of renewable energy grants at the local level to further understand the theoretical model proposed in Chapter Four. I hypothesize that receiving a renewable energy grant increases renewable energy output at the local level. The results support this hypothesis by showing that receiving a renewable energy grant is associated with significant and positive increases in solar energy production. These findings provide further insight into legislative decision-making and the role of renewable energy grants in renewable energy development in the U.S
