日治時期農業統制下的臺灣米穀政策研究(1933~1945) / The research of Taiwan's rice policy in the agricultural control period of Japanese colonization 1933~1945張志明, Chang, Chih Ming Unknown Date (has links)
1933年(昭和8年)日本因全球經濟大蕭條引發「昭和農業恐慌」,加上帝國內部米穀供應嚴重過剩,米價大幅滑落,促使日本政府加強米榖方面的各項統制措施。本文試圖由1933年開始至1945年日本戰敗為止,日本政府為因應米穀供應過剩或者不足所採取的各項統制措施,及其對殖民地臺灣所產生的影響。日本政府實施之米穀統制政策,對臺灣米穀生產造成影響者,如1933年實施的「米穀統制法」、1936年的「米穀自治管理法」、1939年於臺灣內部實施的「臺灣米穀移出管理令」、1942年7月1日施行的「食糧管理法臺灣施行令」、1943年底的「臺灣食糧管理令」、還有1944年年中推行的「米穀增產及供出獎勵相關特別措施」等。由這些米穀統制法令及措施,可以了解日本的臺灣總督府用盡一切方法,就是為了使其最重要的民生主食「稻米」的生產及供應,能達到「自給自足」的目標。臺灣,作為日本殖民帝國下的一員,為配合帝國整體米穀供需穩定,對於「看天吃飯」的米穀生產,悲願地追求其自足目標。臺灣蓬萊米生產的擴大與臺日米價間的互動,連帶影響臺灣糖價及其他農作物的生產,並可藉此了解日本與臺灣之間,因稻米生產而衍生出的統制生產架構。 / In 1933, the world economic recession (the Great Depression) caused the imperial Japan into the so called 「Showa Agricultural Panic」 and made the imperial internal rice supply overwhelmingly surplus. Those made the price of rice in Japan at that time fallen considerably, prompting the Japanese government to strengthen the rice control policies.This article, from 1933 to 1945, tries to explain the impacts of the Japanese government's various rice control policies which responded to the rice oversupply or insufficient upon the colonial Taiwan. The rice control policies Japanese government implemented made great influence upon Taiwan's rice production, such as in 1933, the enactment of the "Rice Control Law" ; in 1936, the enactment of the " Rice Self-management Law " ; in 1939, only in Taiwan enacted, the" Taiwan Rice Shipment Administration Order " ; in July 1 1942," The Staple Food Control Act's Taiwan Enforcement Order ” ; the end of 1943, “ Taiwan's Staple Food Control Administration Order ”; and promulgated in mid-1944 “Special Measures on Enhancing Rice Production and Awarding Shipment ",etc.Through those rice control laws and measures, we can understand the Japanese rulers exhausted to make people's livelihood, the production and supply of the most important staple food "rice", could achieve the goal of “self-sufficiency ".Taiwan, as one part of the Japanese colonial Empire, had to cooperate with the whole Empire’s rice supply and demand as stable as possible. Regarding the rice production which depends on the weather, Taiwan like Japan vows to pursue the goal of “self-sufficiency” with the earnest wish. The expansion of production of the Taiwan Formosan rice (Penglai rice) and the interaction of rice prices between the Taiwan and Japan influenced the Taiwan's sugar price and the production of other crops. Therefore, we can understand the control production structure caused by the rice production between Japan and Taiwan.

Midseason cold tolerance screening for the NSW rice improvement programJohn Smith Unknown Date (has links)
The current rice varieties grown by Australian farmers are susceptible to low temperature events particularly during the reproductive stage of plant development. The best management practices of sowing within the recommended time period and maintaining deep water (20–25 cm) through the microspore development stage only offer limited protection. There is a need to develop more cold tolerant varieties and to do so requires the development of low-temperature screening capacity for the NSW rice breeding program. This study looked at the requirements of adapting a controlled-temperature glasshouse facility to enable screening for tolerance to low temperatures during the reproductive stage of rice development. The investigations were grouped into two areas; 1) the physical aspects of the low temperature facility including the location of plants within the facility and within the tubs used to grow the plants and whether these can influence the reliability of the screening and 2) the biological effects of nitrogen (N) concentration in the plant at panicle initiation (PI) and plant susceptibility to low temperatures, and whether growth stage of the plant relative to PI at the start of low temperature treatment influenced floret sterility. A series of nine experiments were conducted at the Deniliquin Agricultural Research and Advisory Station glasshouse facility using up to five rice varieties selected for their divergence in low-temperature tolerance. One other experiment was conducted in a different facility. The modified glasshouse facility in Deniliquin was effective in providing the targeted screening environment of 27°C day and 13°C night temperature regime. There was however a smaller than expected effect of the low temperature exposure in some of the experiments with sterility following low temperature ranging from 9.9% to 27.7%. There was also a higher than expected level of sterility in the controls (i.e. not exposed to low temperature) with sterility levels up to 58% recorded in one experiment. The causes of these overall effects are not known. Notwithstanding these overall effects there were a number of findings that are important for developing a reliable screening facility. The spatial arrangement of the plants within the low temperature facility effected the level of sterility highlighting the need for experimental design to consider spatial variation. The existence of edge effects was identified within the tubs used to maintain permanent water on the potted plants whereby the outer plants in the tubs were less damaged by the low-temperature treatment. The overall N level in the leaf tissue was low even at the equivalent rate of 250 kg N ha-1 and there was only a very modest and inconsistent response in N concentration at PI to N application rates ranging from 0 to 250 kg ha-1. However, the method of growing the plants in pots and of nitrogen fertiliser application did not alter the N concentration. The concentration was the same when N was added either, on the same day as permanent water application, or three days prior to permanent water application. Also restricting the direction of water movement through the pots and therefore the soil within the pots did not alter the amount of N in the plants at PI. The low plant N concentrations were consistent across two glasshouses in which soil from the same source was used suggesting a soil limitation. A soil test identified that the soil phosphorus (P) was at a level at which plants have responded to P application under field conditions, and the loamy texture of the soil had an associated low cation exchange capacity in comparison to medium to heavy clay soil types commonly associated with rice growing. These factors may have reduced the N retention and uptake and, in part, explain the low injury from the low temperature exposures. In the variety Millin, there was no significant effect of timing of the exposure on sterility until it commenced 12 to 15 days after PI. This is a significant finding for a breeding program that must expose lines of unknown phenological development. It means that even though there are small differences in the rates of development, there is no large effect of this on sterility. However, this response was not seen in the other varieties tested and thus requires further validation. It was difficult to induce repeatable levels of floret sterility in this series of experiments most likely due to the low N concentrations in part due to the properties of the soil used to grow the plants. This highlights the importance of standardising all cultural aspects in order to provide uniform and repeatable screening information. The spatial effects highlight importance of experimental design for effective exposure to low temperature treatments, incorporation of the capacity for spatial analysis in the statistical design, the use of standard variety checks for floret sterility after low temperature treatment, and the determination of N concentration in plant tissue prior to exposure.

Materials for Sustainable ConstructionsFerraro, Rosella Mafalda 21 December 2009 (has links)
White cement has currently received increasing attention due to potential for use in sustainable concrete structures. Based on the U.S. Green Building Council certification practice, the LEED Green Building Rating System for New Construction and Major Renovation (LEED-NC) considers that the reflective quality of white surfaces may help to improve lighting efficiency and reduce temperature fluctuations, resulting in lower heating and cooling with reduction of related energy costs. In addition to the environmental impact, white concrete represents a valuable tool for the aesthetic acceptability of a structure, and can also offer important practical benefits in terms of safety (i.e., light reflection in the dark). In this thesis white concrete was combined with off-white rice husk ash and with a glass fibers reinforced polymer to obtain an innovative composite system able to: a) reduce the energy used for the production of the primary materials, b) decrease the temperature fluctuation in the building resulting in less energy needed for heating and cooling, and c) increase the life of the structure and thereby reduce energy usage for material disposal. It is evident that in applications where aesthetics is the driver, a great deal of attention needs to be devoted to the concrete mixture, but also to durability properties. To further improve the durability of white concrete, novel methodologies were introduced to study the corrosion mechanism of steel embedded in concrete and its effect on the color degradation of white surface. This study demonstrates the validity of the sustainable system made by white cement, OWRHA, and GFRP, and of the methodology introduce to evaluate corrosion and color degradation of reinforced concrete.

Red rice (Oryza sativa L.) ecotype tolerance to herbicides and winter weed management practicesNanson, Weldon Duane 15 May 2009 (has links)
Studies were conducted in 2004, 2005, and 2006 in south Texas to evaluate fall, winter, and spring weed control for commercial rice production, study tillage intensity and herbicide rate interactions for rice production, and determine the tolerance of red rice ecotypes from Texas rice fields using selected herbicides at varying rates. A single application of any herbicide or combination of herbicides was not adequate for weed control throughout the fall, winter, and spring. Fall applications of clomazone plus flumioxazin provided consistent weed control. Addition of flumioxazin to glyphosate provided excellent winter annual grass control with winter application. A residual herbicide, coupled with the proper contact herbicide is the key to extending control. In 2006, all tillage by herbicide treatments in all studies provided ≥ 90% control of all weed species. The conventional tillage treatment with low herbicide input provided the highest rice grain yield in 2005 and 2006, though they were not significantly different from the spring stale seedbed program with medium or high herbicide input in 2006. In 2006, fall stale seedbed treatments were among the lowest in yield. A stale seedbed program may be useful, but with substantial weed pressure, increasing the intensity of herbicide applications is necessary to overcome the absence of tillage. All rice ecotypes were adequately controlled by glyphosate and only one ecotype was found to be tolerant to 2x rates of both imazethapyr and imazamox. All ecotypes were adequately controlled by 2x rates of more than two of the four herbicides which included imazethapy, imazamox, glufosinate, and glyphosate. Ecotypes from the 3.2 group, genetically similar to the ecotype TX4, appear to be the most likely to exhibit tolerance to a given herbicide. Tolerance to glufosinate was found in 70% of the group 3.2 ecotypes. Sixty percent of ecotypes from group 3.1, genetically similar to Oryza rufipogon were not adequately controlled by glufosinate.

Freshwater prawn - rice culture: the development of a sustainable system in the Mekong delta, Vietnam.LAM, My-Lan 23 October 2006 (has links)
In 2003, seeds of Macrobrachium rosenbergii were stocked at 2, 4, and 6 postlarvae/m2 as well as 1, 2 and 3 juveniles/m2 with two culture systems, the integrated and rotational prawn - rice systems. Prawns were fed with pellets twice a day. Water levels in rice plots were arranged at the same levels for both systems. The dissolved oxygen concentrations in the integrated system were lower than in the rotational system. The growth of prawns decreased at higher stocking densities. Prawns in the rotational system grew faster than those in integrated system. The yields ranged from 286 ± 32 to 516 ± 51 and 412 ± 17 to 584 ± 37 kg/ha in the integrated and rotational system at stocking PL, respectively. The yields of prawns ranged from 251 ± 16 to 430 ± 54 and 297 ± 24 to 486 ± 38 kg/ha in integrated and rotational prawn - rice systems stocking juveniles, respectively. However, at higher density, the investment cost significantly increased (P < 0.05), while profit significantly decreased (P < 0.05). At low density, cost benefit ratio and profit were the highest (P < 0.05). Finally, the integrated rice - prawn system gives lower profits than the rotational system.
In 2004, an experiment on the effects of stocking densities (1, 2, 3 and 4 PL/m2) and feeding types, pellets only (P) and pellets + snail meat (PS), on the production and economic aspects of rotational prawn culture in the rice fields were carried out in the same culture facilities. Water levels were 0.3 - 0.6 m in rice-grown areas. Water temperatures were higher than the suitable range for prawns at noon in the hot months. After 7 months, survival rates of prawns were 28.0 - 50.3 %. Final mean weights were 32.0 - 39.8 g/prawn. Yields ranged from 194 ± 82 to 373 ± 32 kg/ha. There was no significant difference between the two types of feeding on production parameters (P > 0.05). The total cost significantly increased at higher densities (P < 0.05) but it was not different between feed types (P > 0.05). Net profit and cost benefit ratio of treatment PS were significantly higher than in treatment P. In the present study, yield (394 ± 22 kg/ha) and cost benefit ratio (1.57 ± 0.07) in treatment PS at 3 PL/m² were significantly the highest (P < 0.05). The effects of stocking densities of postlarvae (0.5, 1 and 2 PL/m2) on the production and economics of prawn culture in the integrated rice - prawn system were studied to affirm the efficiency of this model with low investment. The high temperature in the dry season and low dissolved oxygen after rice harvesting caused small final mean weights, low survival rates and low yields. However, low investment in this system led to good cost benefit ratio.
The on farm trials of rotational rice - prawn farming in the semi-deep water area were monitored with the farmers in six rice fields (0.7 - 1.0 ha). Two treatments of feed types (pellets and pellets + snail meat) were applied at stocking 4 PL/m2. Prawns in two treatments of densities (4 and 5 PL/m2) were fed on a combination of pellets and snail meat. By cull harvesting during the culture period, final mean weights of prawn were improved and larger than 50 g/prawn in all treatments. The prawn yield of treatment 5 PL/m2 was highest (630 ± 22 kg/ha). Net profits in the treatment using a combination of pellets and snail meat were 861 ± 193 US$/ha to 1,019 ± 25 US$/ha for the prawn crop and 1,393 ± 71 US$/ha to 1,576 ± 180 US$/ha for the whole system (prawn crop + dry rice crop).
The integrated two rice crop and one prawn crop system with low investment costs can be applied by poor farmers, while the rotational a rice crop and one prawn crop system with higher operating costs can be practiced by moderately well off and rich farmers. Due to a higher economic return than monoculture of rice or rice - fish systems, rice - freshwater prawn system is spreading very rapidly in the Mekong Delta of Vietnam.
En 2003, de jeunes Macrobrachium rosenbergii furent stockés à 2, 4 et 6 postlarves/m² ainsi qu’à 1, 2 et 3 juvéniles/m² dans deux systèmes de culture: riz et crevettes produits soit en même temps (intégration) soit successivement (rotation). Les crevettes étaient alimentées de granulés deux fois par jour. Les niveaux d’eau dans les casiers rizicoles ont été maintenus identiques dans les 2 systèmes. Les concentrations en oxygène dissous dans le système intégré étaient plus faibles que dans le système en rotation. La croissance des crevettes a diminué aux plus fortes densités. Les crevettes dans le système en rotation ont grandi plus rapidement que dans le système intégré. Les récoltes à partir de postlarves se sont étalées de 286 ± 32 à 516 ± 51 et de 412 ± 17 à 584 ± 37 kg/ha respectivement dans le système intégré et en rotation. Les récoltes à partir de juvéniles se sont étalées de 251 ± 16 à 430 ± 54 et de 297 ± 24 à 486 ± 36 kg/ha respectivement dans le système intégré et en rotation. Cependant, à plus forte densité, les coûts d’investissement augmentent significativement (P < 0,05), tandis que le profit diminue significativement (P < 0,05). A faible densité le rapport coûtbénéfice et le profit ont été les plus élevés (P < 0,05). Finalement, le système intégré riz-crevette donne des profits plus faibles que le système en rotation.
En 2004, une expérience sur les effets de différentes densités de mise en charge (1, 2, 3 et 4 PL/m²) et des types d’aliments, granulés uniquement (G) ou granulés et viande d’escargot (GE), sur la production et les aspects économiques de la culture riz-crevette en rotation ont été effectués dans les mêmes installations que précédemment. Les niveaux d’eau ont varié de 0,3 à 0,6 m dans les zones de production du riz. Les températures de l’eau ont été plus élevées que la température optimale pour la crevette du moins à midi pendant les mois les plus chauds. Après 7 mois, les taux de survie ont été de 28,0 à 50,3 %. Les poids moyens finaux étaient de 32,0 à 39,8 g/crevette. Les récoltes s’étalaient entre 194 ± 82 à 373 ±32 kg/ha. Aucune différence statistique (P < 0,05) concernant les paramètres de production n’a été enregistrée entre les deux types d’alimentation. Les coûts totaux ont augmenté significativement (P < 0,05) à plus fortes densités de mise en charge mais n’étaient pas différents selon les types d’aliments. Le profit net et le rapport coût bénéfice ont été significativement plus élevés avec les aliments combinés (GE) qu’avec les granulés seuls (G). Nos travaux démontrent que la récolte (394 ± 22 kg/ha) et le rapport coût bénéfice du traitement aliment combiné (GE) à 3 PL/:m² donne les meilleurs résultats (P < 0,05).
Les effets de différentes densités de mise en charge de postlarves (0,5, 1 et 2 PL/m²) sur la production et le gain monétaire de l’élevage de crevette d’eau douce dans le système riz –crevette intégré ont été étudiés afin de confirmer l’efficacité de ce modèle basé sur un faible investissement. La température élevée en saison sèche et les faibles concentrations en oxygène dissous de l’eau après la récolte du riz induisent des poids moyens finaux faibles, de faibles taux de survie et de faibles récoltes. Cependant, le faible investissement nécessaire conduit à un bon rapport coût bénéfice.
Les essais sur fermes du système riz-crevette en rotation dans les zones semi-profondes du district de Codo ont été effectués de façon participative avec les fermiers dans six champs de riz (0,7-1,0 ha). Deux types d’aliments (G et GE) ont été testés à la densité de 4 PL/m² et deux types de densité (4 et 5 PL/m²) ont été testés avec l’aliment combiné (GE). Grâce à des récoltes partielles en cours de production, les poids moyens finaux des crevettes ont été améliorés et étaient supérieurs à 50 g/crevette pour tous les traitements. La récolte de crevette à 5 PL/m² a été la plus élevée (630 ± 22 kg/ha). Les profits nets du traitement combinant les 2 types d’aliments (GE) ont varié de 861 ± 193 US$/ha à 1.019 ± 25 US$/ha pour la récolte de crevettes et de 1.393 ± 71 US$/ha à 1.576 ± 180 US$/ha pour l’ensemble du système (riz + crevette).
Le système intégré de deux récoltes de riz et 1 récolte de crevette par an nécessite peu d’investissement et peut être appliquée par les fermiers les plus pauvres tandis que le système une récolte de riz et une récolte de crevette en rotation par an nécessite des investissements plus conséquents et ne peut être appliqué que par des fermiers aisés ou riches. Etant donné que le revenu économique du système riz-crevette est nettement plus élevé que la seule riziculture ou même que la rizipisciculture, ce système est en train de se développer très rapidement dans le delta du Mékong.

Experimental Investigation Of Silicon Carbide Formation From High Energy Ball-milled Rice Husks Via PyrolysisAnik, Alper 01 September 2012 (has links) (PDF)
In this thesis work, it was aimed to optimize the conditions to produce silicon carbide (SiC), from rice husks from Turkish Thrace Region, via pyrolysis.
Rice husks, coked at 500oC, were high energy ball-milled prior to pyrolysis, in order to investigate the effects of ball-milling on pyrolysis temperature, pyrolysis time and morphology of the SiC produced.
Samples of rice husks subjected to different ball milling conditions, were pyrolyzed at temperatures varying from 1500oC to 1600oC and for times varying from ½ / hour to 2 hours. Results of experiments showed that, ball-milling reduced the pyrolysis temperature and pyrolysis time to some extent. It was also experimentally shown that ball-milling favored the formation of SiC particles rather than formation of SiC whisker.

Humanitarian Aid in Question: The Case of Rice Imports to HaitiPotter, Madeleine R 01 April 2013 (has links)
The instance of rice aid in Haiti definitively demands a reevaluation of humanitarian aid in today's world. In this thesis, I will outline the effects of rice aid on Haitian society and theoretically analyze humanitarian aid’s presence in “developing” countries. In addition to ruining many Haitian farmers' livelihoods, rice imports have aggravated Haiti's economic situation and national stability, the consequences of which have fallen primarily on the poor woman. I focus on the effects on the peasant woman in this thesis. Food insecurity remains a crisis. Throughout my thesis, I draw from the texts of scholars Slavoj Zizek, Jacques Rancière, and Noam Chomsky, in order to attempt at understanding what is really going on here. Such theorists illuminate the historical and theoretical analysis of humanitarian aid and the concept of human rights that said-aid seeks to protect. The purpose of my thesis is to shed new light on the business of humanitarian aid, using rice in Haiti as a case study of sorts. I seek to uncover the role international donor institutions have played in reinforcing the fragile state in Haiti as a result of rice aid, arguing that humanitarian aid has done more to prevent than to inspire sustainable progress in Haiti especially in rural Haiti that continually gets hit the hardest during economic crises such as the one brought on by humanitarian aid in the form of rice.

De Pauline Réage à Anne Rice : un pas vers une sexualité démocratiséeBlanchette, Julie January 2010 (has links) (PDF)
Le féminisme possède un champ définitionnel assez vaste, puisqu'il a engendré, avec le temps, une multitude de courants de pensée. Au départ, les féministes s'entendaient pour dire que ce mouvement vise à protéger ce qu'on appelle la « femme » et à créer, de ce fait, des rapports sociaux égalitaires entre celle-ci et l'homme. Toutefois, cette conception du féminisme a été, plus tard, remise en question par d'autres militants que l'on nomme aujourd'hui les postféministes. Pauline Réage fait, de par son chef-d'oeuvre pornographique Histoire d'O (1954), partie des adeptes de ce nouveau féminisme, qui est aussi subdivisé en sous-courants. Selon cette auteure, la représentation de la femme-esclave, dans son roman, ne signifie pas le contrôle de l'homme sur la femme, puisque la soumission féminine n'est qu'un simulacre: c'est en faisant croire aux hommes qu'ils la dominent qu'elle réussit à obtenir ce qu'elle veut. D'autres féministes plus conventionnelles estiment que le personnage féminin réagien est trop bête pour revendiquer ses droits. Anne Rice, quant à elle, dans sa trilogie intitulée The Claiming of Sleeping Beauty (1983), Beauty's Punishment (1984) et Beauty's Release (1985), conteste également Histoire d'O, mais elle le fait, dans son cas, en introduisant la figure de l'androgyne. En effet, toute forme de dépolarisation sexuelle permet, dans son oeuvre, d'éviter l'ostracisation du sexe féminin, car la totalité des personnages sont constitués des mêmes traits. Ainsi, par le biais de la transposition d'Histoire d'O, oeuvre dans laquelle la discrimination sexuelle est évidente, Rice nous amène dans un univers où les différences physiques entre les personnages sont individuelles, et non sexuelles, et où les personnages font preuve d'un dualisme psychique, dans la mesure où il y a alternance du féminin et du masculin. Il ne s'agit pas, dans son texte littéraire, d'une masculinisation de la femme ou d'une féminisation de l'homme, mais il s'agit plutôt d'une humanisation de l'être. L'approche essentialiste des sexes dans le roman de Réage s'opposera à l'approche humaniste des personnages riciens. Enfin, quant à l'analyse des actions des personnages, nous verrons que la punition de la femme sexuée chez Réage s'oppose à l'émancipation sexuelle des personnages riciens. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : Littérature pornographique, Pauline Réage, Anne Rice, Transposition, Polarisation sexuelle, Androgynie, Féminisme.
