Size at Maturity of Female American Lobsters from an Estuarine and Coastal Population

The size at which female lobsters reach sexual maturity was determined for two populations that inhabit waters along the coast of New Hampshire. One group was captured in the Great Bay estuary, where water temperatures in the summer typically average between 17 C and 20 C. The other gorup of lobsters resided in coastal waters, near the Isles of Shoals, where the water temperature was much colder during the summer (11-15 C). Maturity was assessed using criteria that included the following: ovarian classification; abdominal width/carapce length (CL) ratio; and the size frequency distribution of berried females. All the techniques yielded similar results and consistently demonstrated that female lobsters in the estuary matured at a smaller size than those in colder coastal waters. The smallest mature females from Great Bay were 72 mm in CL, with 50% reaching sexual maturity by 83 mm CL and all becoming mature by 89 mm CL. The difference in the proportion of mature lobsters in the estuarine versus coastal populations was much greater in the smaler size classes than in the larger size claases, suggesting a mixing of the two populations, most likely due to females from Great Bay migrating into coastal waters

QUANTIFYING THE DIFFERENCES IN MANAGEMENT GOALS AND TECHNOLOGY CHOICE IN PEANUT PRODUCTION

Precision farming and whole-field farming are compared with respect to yields, net present value of returns above nitrogen and water costs (NPVR), and nitrogen application rates to determine the differences in management practices. Precision farming yields, NPVR, and nitrogen application levels are then compared under yield maximizing verses profit maximizing strategies. The results quantify the gains from technology and management goals of peanut producers and suggest the technology effect is greater than the management effect.Crop Production/Industries,

Carrot or stick? – Would information concerning the economic value of nutrient losses, and their impact on food quality achieve greater environmental protection than regulation?

This report was presented at the UK Organic Research 2002 Conference. Organic standards have, since their origin (Soil Association 1967) required high standards of manure management, but in reality, these have not been implemented, possibly because of perceived costs of improved handling. However, a cost/benefit analysis of intermediate steps of nutrient conservation and manure handling may provide a practical solution, optimising retention of nutrients, financial and time inputs and environmental protection. Recent research on composting with conventional manures has quantified nutrient losses from heaps with different treatments (Parkinson et al, 2001). Financial and environmental costs and benefits of different management approaches are discussed

EXPLORING LITERACIES IN THE ASSEMBLAGE OF ADULT EDUCATION ENGLISH FOR SPEAKERS OF OTHER LANGUAGES CLASSROOMS

The purpose of this dissertation is to provide a posthuman perspective of adult second language and literacy learning using the philosophy of Gilles Deleuze and his collaborative work with Félix Guattari, Masny’s (2005/6) multiple literacies theory or MLT, and DeLanda’s (2016) assemblage theory. Thinking with these scholars, I employ a post-qualitative, posthuman MLT conceptual framework to study literacy as a process that flows through and connects with globally-diverse students, languages, worldviews, and texts in the assemblage of adult education, English for speakers of other languages (ESOL) classrooms. I posit this assemblage as a remarkable and important context for literacy research because of its heterogeneity and potential to produce creative expressions of multiple literacies. With the MLT framework, I explore expressions of multiple literacies as emergent multilingual subjectivities that deterritorialize commonsense worldviews about adult second language and literacy learning. I use observations and student work as data to map a posthuman perspective of adult education to address three research questions: (1) How might we use an MLT framework to explore multiple literacies in adult education ESOL classrooms? (2) With an MLT framework, how are multiple literacies expressed in adult education ESOL classrooms? (3) What are the benefits and implications of an MLT perspective for the field? This project offers a counter-story about the research context and problematizes qualitative inquiry by asking questions and raising problems that might otherwise be invisible. What emerges is a feminist practice of immanent ethics with important implications for the field of adult literacy and second language learning

Recruiting and Retaining Teachers: Keys to Improving the Philadelphia Public Schools

In 1996 the Consortium for Policy Research in Education (CPRE) at the University of Pennsylvania and its partner, Research for Action (RFA) were charged by the Children Achieving Challenge with the evaluation of Children Achieving. Between the 1995-1996 and 2000-2001 school years, CPRE and RFA researchers interviewed hundreds of teachers, principals, parents, students, District officials, and civic leaders; sat in on meetings where the plan was designed, debated, and revised; observed its implementation in classrooms and schools; conducted two system-wide surveys of teachers; and carried out independent analyses of the District’s test results and other indicators of system performance. An outline of the research methods used by CPRE and RFA is included in this report
