Where Stories Collide : Montage and the Short Story Cycle

This thesis uses Sergei Eisenstein’s filmic theories of montage to examine the modernist American short story cycle, a genre of independent short stories that work together to create a larger and interrelated whole. Similar to the shot-by-shot editing process of montage, the story cycle builds its intertextual meaning story-by-story from an aggregate of abrupt narrative transitions and juxtapositions. Eisenstein famously felt that montage, the editing together of film fragments, was not a process of linkage, but of collision –each radically different shot in a film should crash into the next shot, until audience members were intellectually provoked into synthesizing these collisions through dialectical processes. I offer montage as an interpretive strategy for negotiating the narrative collisions in story cycles such as Sherwood Anderson’s Winesburg, Ohio, William Faulkner’s Go Down, Moses, and Eudora Welty’s The Golden Apples. For Go Down, Moses, I argue that Eisenstein’s politically rendered “montage of attractions” provides a template for investigating the shock tactics behind Faulkner’s chronologically and racially entangled stories of whites and African Americans. For The Golden Apples, I consider the opposites and doubles in Welty’s fiction with Eisenstein’s similar belief in the “opposing passions” of the world. Not only, then, do I suggest that the modernist story cycle bears a cinematic influence, but I also offer Eisenstein’s theories of montage and collision as a heuristic for formal, thematic, and even political patterns in a genre infamous for its resistance to definition and classification.

Trade Costs, Quality, and The Skill Premium

We develop a monopolistic competition model with nonhomothetic factor input bundles where increasing quality requires increasing use of skilled workers. As a result more skill abundant countries export higher quality, higher priced goods. Using a multicountry dataset we test and confirm the findings in Schott (2004) of a positive effect of skill abundance on unit values identified with US data. We extend the core model with per unit trade costs leading to the Washington-apples effect that goods shipped over larger distance are of higher quality. The combination of high-quality goods being relatively skill intensive with the Washington-apples effect implies that countries at a larger distance from their trading partners display a higher skill premium. Simulating our model we find that a doubling of distance of a country relative to all its trading partners raises the skill premium in a country by about 2.3 percent.

Grapholita molesta : caracterización de una cría artificial

Grapholita molesta (Busck) es considerada plaga principal del duraznero en Mendoza. Sus larvas han sido criadas, en condiciones de laboratorio, con dietas naturales por diversos autores. Los objetivos fueron: 1. poner a punto la cría artificial de la especie; 2. diseñar una jaula para el apareamiento y la oviposición de los adultos; 3. evaluar la eficiencia de la jaula y la dieta larvaria mediante grados día, ciclo biológico, peso de pupas, recuperación de huevoadulto, fecundidad, viabilidad y longevidad. La cría artificial de una especie constituye una herramienta para profundizar sus conocimientos bioetoecológicos y, en consecuencia, aplicarlos en su control. En 1996 se fundó una cría con larvas salvajes alimentadas con manzanas verdes pequeñas del cv. Granny Smith. Los adultos se desarrollaron en una jaula especialmente diseñada. En el ciclo biológico, la recuperación huevo-adulto y la fecundidad se obtuvieron valores superiores a los citados por otros autores pero no ocurrió lo mismo con las otras variables. La cría artificial de Grapholita molesta (Busck) se logró desarrollar por 37 generaciones y la alta fecundidad obtenida es una clave fundamental en el éxito de su mantenimiento.

Efecto del ANA, Carbaryl y BAP en raleo de manzanos

Para evaluar el efecto raleante de ANA, BAP y Carbaryl sobre los rendimientos y la calidad a cosecha en frutos de manzano cv. Royal Gala se los trató -en Luján de Cuyo (Mendoza, Argentina)- con pulverizaciones aplicadas a los 23 días después de plena floración de ANA (10 y 15 ppm); BAP (50 ppm); Carbaryl (1200 ppm) y las siguientes combinaciones de ANA 10 y 15 ppm y Carbaryl 1200 ppm. ANA 10 ppm afectó el número total de frutos retenidos a cosecha y, por lo tanto, los rendimientos totales. Carbaryl provocó caídas de frutos al principio pero, a cosecha, esa diferencia se perdió debido a las caídas de precosecha. El peso promedio y tamaño también aumentó con ANA 10 ppm. Igual efecto produjo sobre el contenido de sólidos solubles y color de pulpa. Cuando aumentó la dosis de ANA el efecto fue negativo. BAP no incidió en ninguno de los parámetros analizados. Bajo las condiciones de este ensayo el mejor efecto raleante se obtuvo con ANA 10 ppm, aplicados con un tamaño de fruto de 12 mm.

Nondestructive quantification of chemical and physical properties of fruits by time-resolved reflectance spectroscopy in the wavelength range 650-1000 nm

Time-resolved reflectance spectroscopy can be used to assess nondestructively the bulk (rather than the superficial) optical properties of highly diffusive media. A fully automated system for time-resolved reflectance spectroscopy was used to evaluate the absorption and the transport scattering spectra of fruits in the red and the near-infrared regions. In particular, data were collected in the range 650-1000 nm from three varieties of apples and from peaches, kiwifruits, and tomatoes. The absorption spectra were usually dominated by the water peak near 970 nm, whereas chlorophyll was detected at 675 nm. For ail species the scattering decreased progressively with increasing wavelength. A best fit to water and chlorophyll absorption line shapes and to Mie theory permitted the estimation of water and chlorophyll content and the average size of scattering centers in the bulls; of intact fruits.

Bruise susceptibility in pome fruits under different loading and storage conditions

Samples of "Golden" and "Granny Smith" apples and "Conference" and "Doyenne of Cornice" pears have been tested. A great effect of storage conditions has been detected for pear but not for apple varieties. Both apple cultivars show to be equally resistant to quasi-static and to dinamic loading while pear varieties show great differences. All these effects can be quantified in order to describe mathematically species and varieties behavior.

Fruit quality sensing:Post-harvest ripeness

Firmness sensing of selected varieties of apples, pears and avocado fruits has been developed using a nondestructive impact technique. In addition to firmness measurements, postharvest ripeness of apples and pears was monitored by spectrophotometric reflectance measurements, and that of avocadoes by Hunter colour measurements. The data obtained from firmness sensing were analyzed by three analytical procedures: principal component, correlation and regression, and stepwise discriminant analysis. A new software was developed to control the impact test, analyse the data, and sort the fruit into specified classes, based on the criteria obtained from a training procedure. Similar procedures were used to analyse the reflectance and colour data. Both sensing systems were able to classify fruits w i th good accuracy.

Relationship between solar radiation on watercore on apple fruit assessed with MRI

This work is a preliminary studio of the possibility of assess a relationship between solar radiation and watercore development on apple fruit, during maturation, using a non destructive method such as Magnetic Resonance Imaging (MRI). For such purpose, several low cost solar radiation sensors were designed for the trial and placed at 2 different heights (1.5 and 2.5 m) on 6 adult ?Esperiega? apple trees, in a commercial orchard in Ademuz (Valencia). Sensors were connected along 27 days, during the end of the growth period and start of the fruit maturation process, and radiation measurements of the a-Si sensors were recorded every 1 minute. At the end of this period, fruits from the upper and the lower part of the canopy of each tree were harvested. In all, 152 apples were collected and images with MRI. A Principal Component Analysis, perfomed over the histograms of the images, as well as segmentation methods were performed on the MR images in order to find a pattern involving solar radiation and watercore incidence.

Influence of climate change on the flowering of temperate fruit trees

It is well known that winter chilling is necessary for the flowering of temperate trees. The chilling requirement is a criterion for choosing a species or variety at a given location. Also chemistry products can be used for reducing the chilling-hours needs but make our production more expensive. This study first analysed the observed values of chilling hours for some representative agricultural locations in Spain for the last three decades and their projected changes under climate change scenarios. Usually the chilling is measured and calculated as chilling-hours, and different methods have been used to calculate them (e.g. Richarson et al., 1974 among others) according to the species considered. For our objective North Carolina method (Shaltout and Unrath, 1983) was applied for apples, Utah method (Richardson et al. 1974) for peach and grapevine and the approach used by De Melo-Abreu et al. (2004) for olive trees. The influence of climate change in temperate trees was studied by calculating projections of chilling-hours with climate data from Regional Climate Models (RCMs) at high resolution (25 km) from the European Project ENSEMBLES (http://www.ensembles-eu.org/). These projections will allow for analysing the modelled variations of chill-hours between 2nd half of 20C and 1st half of 21C at the study locations.

Impact parameters related to bruising in selected fruits.

Impact testing with an instrumented free-fallingmass (50.4 g) device was applied to three varities of pears and two varieties of apples, forincreasing ripeness stages and impact energy (2 to 20 cm drops). Impact parameters were studied in relation to bruise and to ripeness, establishing relations between them and with the different characteristics of the fruits.

Impact bruises in pomaceae fruits: Evaluation methods and structural features.

Using a laboratory impact tester, impacts were applied to fruits of different varieties of apples and pears. The response to impact was analized, and many parameters were recorded, to be correlated to bruise susceptibility and to ripeness changes. Different methods for the detection and evaluation of the bruised Area and its features were studied, using direct observation and various reactives. Different types of bruises were established.

Impact parameters in relation to bruising and other fruit properties.

Impact response in fruits, primarily appl.es and pears (Pomaceae fruits), has been studied during the last five years. Using a laboratory impact testing device and also free-fall tests of instrumented apples, a significant body of results has been established, relative to the parameters which best characterize the impact response of these materials, and to their correlation with bruise damage, variety and ripeness level of the fruits. Bruise damage, measured as the size and/or volume of the affected fruit tissue is related primarily to applied energy (i.e. mainly drop height) for a given variety at a given ripeness stage. The relevant impact response parameters are maximum deformation (DM), permanent deformation (DP), maximum impulse (IM), maximum impact force (FM), maximum value of the force/time slope during impact (F/T) and impact time (T). The effect of ripeness differences was also studied in selected varieties of pears, being the most relevant parameters: maximum force (FM) and F/T slope.

Sensing physical stage of fruits by their response to non destructive impacts.

Fruits of two varieties of both apples and pears were tested in the laboratory to measure their response to a small energy impact applied by an impact tester. Samples of fruits of increasing maturity were tested during several weeks. Non-destructive impacts and other destructive and non-destructive measurements of post-harvest ripeness were applied. A new software was created to control the impact test, calculate the eleven parameters, and sort out the fruit. This software needs a data base and may create new ones. The implementation of an on-line impact device for automatic detection of texture is being designed (patent pending).

Factors influencing apple and pear physical properties and bruise susceptibility.

Fruit turgidity and firmness have shown to influence impact bruise susceptibility in apples and pears. Analysis of the impact response showed that stresses in the tissues are higher in turgid fruits, so they are more susceptible to bruising. A physical parameter, deformation at skin puncture, was able to detect fruit turgidity changes and showed to be related to bruise susceptibility.
