Making a market for Miscanthus: Can new contract designs solve the biofuel investment hold-up problem?
Full text linkWe present designs for optimal contracts to solve the investment hold-up problem for perennial crops for the biofuel industry. A fixed-price contract is ex-ante efficient but renegotiation-proof for a limited range of discount parameters. A perfectly- indexed contract is both renegotiation-proof and ex-post efficient. Provided long-run land prices are stationary, the expected cost for both contracts converges to the long-run expected price of land for a risk-neutral farmer.Biofuels, Miscanthus, contract theory, industrial organization, renegotiation-proof contract, Marketing,

A rainbow in the clouds: planting spiritual reconciliation in mama's southern garden, 2016
No full textThrough a content analysis of the maternal relationships in Maya Angelous I Know Why the Caged Bird Sings and Alice Walkers In Search of Our Mothers Gardens, the author evaluates how southern black women writers construct black motherhood. This study is based on the premise that Eurocentric paradigms of motherhood confine black mothers to controlling images that continue to criminalize, distort, and devalue black motherhood. The researcher finds that the institution of black motherhood exists independently of Eurocentric paradigms. The conclusions drawn from these findings suggest that black women writers construct motherhood in terms of Womanist leadership. In the aforementioned memoirs, Womanist leadership is learned and defined in the black church. In summation, this thesis finds that southern black women writers use spiritual reconciliation as a form of Womanist leadership.

Rarefied gas flows in microscale geometries : a hybrid simulation method
Full text linkAccurate predictions of the flow behaviour in microscale geometries are needed, for example, to design and optimise micro devices, and to ensure their safety/reliability. Rarefied gas flows in such geometries tend, however, to be far from local thermodynamic equilibrium, meaning that the flow behaviour cannot be described by conventional fluid mechanics. Alternative approaches for modelling 'non-equilibrium' gas flows have been proposed in recent years; because analytical solution methods are subject to significant limitations, the direct simulation Monte Carlo (DSMC) method is, at present, the most practical numerical simulation tool for dilute gases. Unfortunately, the computational expense of tracking and computing collisions between thousands (or perhaps millions) of DSMC particles means that simulating the scales of realistic flow problems can require months (or even years) of computing time. This has resulted in the development of continuum-DSMC 'hybrid' methods, which aim to combine the efficiency of a conventional continuum-fluid description with the detail and accuracy of the DSMC method. This thesis focuses on the development of a continuum-DSMC method that offers a more general approach than existing methods. Using a heterogeneous framework with a field-wise coupling strategy, this new method is not subject to the limitations of the well-known domain decomposition framework, or the restrictions of the heterogeneous point-wise coupling approach. The continuum-fluid description is applied across the entire flow field, while the DSMC method is performed in dispersed micro elements that can be any size and at any location; these elements then provide the continuum description with updated constitutive and boundary information. Unlike most methods in the literature, the coupling strategy presented here is able to cope with heat transfer, and so non-isothermal flows can be simulated. Testing and validation of this new continuum-DSMC method is performed by simulating a number of benchmark cases and comparing the results with full DSMC solutions of the same cases. Two 1D flow problems are considered: a micro Fourier flow problem tests the energy coupling procedure of the method, and a high-speed micro Couette flow problem demonstrates the full coupling algorithm. In general, the method's accuracy is found to depend on the arrangement of the micro elements - with sufficient micro resolution, good agreement with the equivalent full DSMC simulations can be obtained. Although the hybrid method offers no computational speed-up over the full DSMC simulations for several of these 1D test cases and only modest speed-ups for the others, both of these 1D ow problems are simulated only to validate the coupling strategy of the method. Considerable speed-ups are offered by the method when simulating a larger and more realistic flow problem: a microchannel with a high-aspect-ratio cross-section acts as a representative geometry for modelling a gas flow through a narrow microscale crack. While the limitations of existing hybrid methods preclude their use for this type of high-aspect-ratio geometry, the new hybrid method is able to model this problem under isothermal and non-isothermal conditions. The implementation of the method is simplified to 2D by assuming that the flow variation in the streamwise direction is negligible, i.e. the method is applied to the microchannel cross-section only. Accurate predictions of the mass flow rate and the streamwise velocity field are obtained for a number of test cases; accurate predictions of the temperature field are also obtained when there is a temperature difference between the bounding walls.Accurate predictions of the flow behaviour in microscale geometries are needed, for example, to design and optimise micro devices, and to ensure their safety/reliability.

A case study: the development of Stephanie's algebraic reasoning
No full textThis research provides an analysis of the mathematical growth and development of one student, Stephanie, as she worked on early algebra tasks during her eighth-grade year as part of a teaching experiment. Stephanie was among the original participants in a longitudinal study which investigated how students develop mathematical ideas under conditions that fostered independent exploration, reasoning, and justification of ideas (Maher, 2005). A qualitative approach based on the analytical model described by Powell, Francisco, and Maher (2003), was taken in analyzing videotape data from the Robert B. Davis Institute of Learning archive, along with student work. Seven task-based interview sessions were analyzed, spanning a six month period, beginning from November 8, 1995 to April 17, 1996. The research focused on Stephanie’s algebraic reasoning; in particular, how she built an understanding of the binomial theorem and related it to Pascal’s triangle. Stephanie’s representations, her explanations and justifications, and her methods of dealing with obstacles to understanding, were all examined and provided the basis for this research. The analysis shows that Stephanie built her mathematical understanding through the development of multiple representations of concepts and moved fluidly between and among the representations that she organized into ‘symbolic’ and ‘visual’ representations. Symbolic representations included algebraic expressions, combinatorics notation, and Pascal’s triangle while visual representations included drawings, tables, models formed by algebra blocks and other manipulatives, and towers built with unifix cubes. Furthermore, through Stephanie’s explanations and justification of her representations and reasoning in general, she invented strategies to convince herself as well as the researchers that she had fulfilled the requirements of the problem task. When dealing with obstacles to her understanding such as lack of information, or calculating obstacles, Stephanie acquired the use of several heuristic methods in order to overcome them. These included the use of substituting in numbers in order to test a conjecture; returning to basic meaning; drawing diagrams; building models; and considering a simpler problem. Throughout the task-based interviews, Stephanie retrieved knowledge from her earlier problem solving and extended this knowledge to build new ideas, while tackling more challenging problems. In particular, Stephanie mapped the coefficients in the binomial expansion to particular rows in Pascal’s Triangle; she connected these ideas to her problem solving from earlier work in the elementary grades. The findings are relevant to the timing and method of early algebraic instruction in schools.Ed.D.Includes bibliographical referencesby Eman Y. Aboelnag
Aprendizaje de la lengua en las aulas de primaria : nociones de sujeto, aprendizaje y lengua en los programas escolares en el Uruguay actual
Full text linkTesis Maestría en Psicología y EducaciónEsta investigación se propone realizar un recorrido por los programas escolares de Primaria vigentes en nuestro país para vislumbrar las nociones de sujeto, aprendizaje y lengua que subyacen en ellos. Desde la vuelta de la democracia en nuestro país en 1985 y la universalización real de Escuela Primaria, ha sido tema de preocupación por los bajos rendimientos de los alumnos en el área de lenguaje, conocimiento primordial del ser humano, la puerta de entrada para cualquier otro saber y para el acontecer de un sujeto. A través de este recorrido se quiere hacer visible las nociones que se encuentran y cómo esas nociones puedan facilitar o no el acceso a este saber tan importante. También se analizará el nuevo Marco Curricular Nacional (2022) que entró en vigencia este año y está ingresando en las aulas de primero y segundo año de Primaria. Esta investigación se realiza en el marco de las áreas de conocimiento de la psicología de la educación, y uno de los aspectos que se busca es contribuir a generar una mayor comprensión sobre las nociones de sujeto, lenguaje y aprendizaje presentes en las aulas escolares del Uruguay y cuáles son las que devienen con el nuevo Marco Curricular Nacional. Se analiza la documentación desde un enfoque metodológico cualitativo, a través de la herramienta análisis de discurso tal como lo plantea Foucault en La arqueología del saber (1969). El autor da cuenta de que el discurso no es transparente, sino que en él surge «un oscuro conjunto de reglas anónimas», el discurso se va transformando según el momento histórico, lugar y situación social. Esos elementos se deben tomar en cuenta al realizar su lectura. Dichos documentos a analizar reflejan el momento histórico, político y social del país y cómo eso penetra las aulas escolares. La Escuela es una muestra de la sociedad, es imposible que la institución se mantenga al margen de ella, develando el discurso de estos documentos podemos observar los aconteceres históricos y políticos en la Escuela. En el marco teórico se realiza un recorrido por las diferentes teorías psicológicas para dar cuenta luego de cuáles de ellos predominan más y por qué y cuáles quedan afuera y analizar el porqué de las ausencias. En el análisis de los distintos documentos se pudo observar una predominancia de las nociones de sujeto cognoscente proveniente de la teoría piagetiana y el sujeto sociohistórico y en segundo plano la teoría cognitiva conductual y la reciente inserción de las neurociencias. A su vez se entiende el aprendizaje y la lengua desde las dos perspectivas teóricas predominantes. Cabe destacar que la gran ausente es la teoría psicoanalítica. ¿Por qué se entiende que es importante destacar esta ausencia? Porque el psicoanálisis da lugar a pensar el dispositivo Escuela desde la imposibilidad para que efectivamente los niños tengan acceso a la compleja red simbólica de nuestra cultura. La lengua es la llave para ingresar al complejo mundo simbólico que estamos inmersos los sujetos.This paper proposes to take a tour of the current Primary school programs in our country to glimpse the notions of subject, learning and language that underlie them. Since the return of democracy in our country in 1985 and the real universalization of Primary School, it has been a matter of concern for the low performance of students in the area of language, essential knowledge of the human being, the gateway to any other knowledge and for the occurrence of a subject. Through this journey we want to make visible the notions that are found and how these notions can facilitate or not access to this important knowledge. The new National Curricular Framework (2022) that came into effect this year and is entering the first and second grade classrooms will also be analyzed. This research is carried out within the framework of the areas of knowledge of educational psychology, and one of the aspects that is sought is to contribute to generating a greater understanding of the notions of subject, language and learning present in school classrooms in Uruguay. and which are those that become with the new National Curricular Framework. The documentation is analyzed from a qualitative methodological approach, through the discourse analysis tool as proposed by Foucault in La arqueología del saber (1969). The author realizes that the discourse is not transparent, but that "a dark set of anonymous rules" arises in it, the discourse is transformed according to the historical moment, place and social situation. These elements should be taken into account when reading. These documents to be analyzed reflect the historical, political and social moment of the country and how all this penetrates the school classrooms. The School is a sample of society, it is impossible for the institution to remain outside of it, revealing the discourse of these documents we can observe the historical and political events in the School. In the theoretical framework, a tour of the different psychological theories is carried out to account for which of them predominate the most and why and which ones are left out and to analyze the reason for the absences. In the analysis of the different documents, it was possible to observe a predominance of the notions of the knowing subject coming from the Piagetian theory and the sociohistorical subject and, in the background, the cognitive behavioral theory and the recent insertion of neurosciences. At the same time, learning and language are understood from the two predominant theoretical perspectives. It should be noted that the great absentee is psychoanalytic theory. Why is it understood that it is important to highlight this absence? Because psychoanalysis gives rise to thinking about the School device from the impossibility so that children actually have access to the complex symbolic network of our culture. Language is the key to enter the complex symbolic world that we subjects are immersed in

Boundary conditions for molecular dynamics simulations of water transport through nanotubes
Full text linkThis article compares both new and commonly used boundary conditions for generating pressure-driven water flows through carbon nanotubes in molecular dynamics simulations. Three systems are considered: (1) a finite carbon nanotube membrane with streamwise periodicity and ‘gravity’-type Gaussian forcing, (2) a non-periodic finite carbon nanotube membrane with reservoir pressure control, and (3) an infinite carbon nanotube with periodicity and ‘gravity’-type uniform forcing. Comparison between these focuses on the flow behaviour, in particular the mass flow rate and pressure gradient along the carbon nanotube, as well as the radial distribution of water density inside the carbon nanotube. Similar flow behaviour is observed in both membrane systems, with the level of user input required for such simulations found to be largely dependent on the state controllers selected for use in the reservoirs. While System 1 is simple to implement in common molecular dynamics codes, System 2 is more complicated, and the selection of control parameters is less straightforward. A large pressure difference is required between the water reservoirs in these systems to compensate for large pressure losses sustained at the entrance and exit of the nanotube. Despite a simple set-up and a dramatic increase in computational efficiency, the infinite length carbon nanotube in System 3 does not account for these significant inlet and outlet effects, meaning that a much smaller pressure gradient is required to achieve a specified mass flow rate. The infinite tube set-up also restricts natural flow development along the carbon nanotube due to the explicit control of the fluid. Observation of radial density profiles suggests that this results in over-constraint of the water molecules in the tube
