Product design in the context of the social needs in less industrialised economies

This thesis is related to the subject of technical innovation, specifically to the activity of design in microenterprises operating in less industrialised economies. Design here is understood as a process, which is not the sole domain of formally trained categories such as engineers, architects or industrial designers. The 'professional boundary' discussion in this investigation is perceived as secondary as, in this context, products are designed, copied or adapted by workers, entrepreneurs themselves, or directly by the poor community. Design capacity at this level is considered to be important both in relation to the conception of capital and consumer goods and to the building up of technical knowledge. Although professional design emerged in Latin America little over three decades ago, this activity has remained marginalised throughout industry. Design activity tends to be concentrated in some product categories in the formalised industrial sector. For microenterprises operating informally, industrial design appears to be unknown. The existing literature pays little attention to 'informal design' capacity. Other areas of knowledge, such as development economies, recognise the importance of microenterprises and technological capability but neglect the potential role of industrial design in small manufacturing units. The management literature, though it focuses on technical innovation and design, has also paid little attention to 'informal design'. In less industrialised economies this neglect is felt by the lack of programmes specifically tailored to create or stimulate 'informal design'. There is a need for recognition of 'informal design' capacity and for the implementation of programmes which specifically target design as a central activity in the manufacturing firm, independent of their size and technological capability. Addressing 'design by the poor for the poor', requires a down-to-earth approach.

Regional growth, structural change, and natural disaster

Hurricanes, earthquakes, floods, and other serious natural hazards have been attributed with causing changes in regional economic growth, income, employment, and wealth. Natural disasters are said to cause; (1) an acceleration of existing economic trends; (2) an expansion of employment and income, due to recovery operations (the so-called silver lining); and (3) an alteration in the structure of regional economic activity due to changes in "intra" and "inter" regional trading patterns, and technological change.^ Theoretical and stylized disaster simulations (Cochrane 1975; Haas, Cochrane, and Kates 1977; Petak et al. 1982; Ellson et al. 1983, 1984; Boisvert 1992; Brookshire and McKee 1992) point towards a wide scope of possible negative and long lasting impacts upon economic activity and structure. This work examines the consequences of Hurricane Andrew on Dade County's economy. Following the work of Ellson et al. (1984), Guimaraes et al. (1993), and West and Lenze (1993; 1994), a regional econometric forecasting model (DCEFM) using a framework of "with" and "without" the hurricane is constructed and utilized to assess Hurricane Andrew's impact on the structure and level of economic activity in Dade County, Florida.^ The results of the simulation exercises show that the direct economic impact associated with Hurricane Andrew on Dade County is of short duration, and of isolated sectoral impact, with impact generally limited to construction, TCP (transportation, communications, and public utilities), and agricultural sectors. Regional growth, and changes in income and employment reacted directly to, and within the range and direction set by national economic activity. The simulations also lead to the conclusion that areal extent, infrastructure, and sector specific damages or impacts, as opposed to monetary losses, are the primary determinants of a disaster's effects upon employment, income, growth, and economic structure. ^

Proteção diferencial de transformadores de potência utilizando a transformada Wavelet

About 10% of faults involving the electrical system occurs in power transformers. Therefore, the protection applied to the power transformers is essential to ensure the continuous operation of this device and the efficiency of the electrical system. Among the protection functions applied to power transformers, the differential protection appears as one of the main schemes, presenting reliable discrimination between internal faults and external faults or inrush currents. However, when using the low frequency components of the differential currents flowing through the transformer, the main difficulty of the conventional methods of differential protection is the delay for detection of the events. However, internal faults, external faults and other disturbances related to the transformer operation present transient and can be appropriately detected by the wavelet transform. In this paper is proposed the development of a wavelet-based differential protection for detection and identification of external faults to the transformer, internal faults, and transformer energizing by using the wavelet coefficient energy of the differential currents. The obtained results reveal the advantages of using of the wavelet transform in the differential protection compared to conventional protection, since it provides reliability and speed in detection of these events.

Influência do horário de trabalho, do gênero e de um programa de educação sobre o sono no ciclo sono/vigília de professores do ensino fundamental e médio

The teaching profession is often associated with extensive workload inside and outside the classroom, poor teaching conditions, among other challenges that can cause sleep problems. These problems may be even greater in women, due to the professional and domestic work hours and to the major sleep necessity. Considering that sleeping problems may result from the practice of poor sleep habits, sleep education programs are conducted with the aim to reduce sleep deprivation, irregularity on sleep schedules, daytime sleepiness and improve sleep quality. In this sense, the objective of this study is to evaluate the influence of working hours, gender and a sleep education program on sleeping habits, quality of sleep, daytime sleepiness and the level of stress in teachers of elementary and secondary education. For that, teachers filled the questionnaires that assessed: 1. Sleeping habits (Sleep & Health), 2. Chronotype (Horne & Ostberg), 3. Daytime sleepiness (Epworth Sleepiness Scale), 4. Sleep Quality (Pittsburgh Sleep Quality Index), 5. Level of stress (The Inventory of Stress for Adults of Lipp) and 6. Daily pattern of sleep/wake cycle (Sleep Diary). The questionnaires 1, 4, 5 and 6 were repeated 3 weeks after the sleep education program. Teachers who begin work in the morning (7:11 ± 0:11 h) wake up earlier in the week and often have poor sleep quality compared to those who start in the afternoon (13:04 ± 00:12 h). Among those who begin work in the morning, the intermediate types and those with an evening tendency were more irregular in the wake up time than morning types and increased sleep duration on weekend. In relation to gender, women had longer sleep duration than men, although the majority presented excessive daytime sleepiness and poor sleep quality. However, when work schedule and age are similar between genders, the difference in sleep duration becomes a tendency and the difference in the percentage of excessive daytime sleepiness disappears, but the poor sleep quality persists in women. With respect to teachers who have gone through the sleep education program, there was an increase in knowledge about the subject, which may have contributed to the reduction in the frequency of coffee consumption close to bedtime and to the sleep quality improved in 18 % of participants. In the control group, there were random differences in knowledge in 3rd stage, and sleep quality improved in only 9% of teachers. The participation in the sleep education program was not enough to change the hours of sleep and decrease stress of teachers. Therefore, the start time school in the morning was preponderant in determining the wake up time of teachers, especially for intermediates types and those with an evening tendency. Furthermore, the poor quality of sleep was more common in women, and the sleep education program contributed to increase knowledge on the subject and to improve sleep quality.

Figuraciones de la esclavitud en novelas y ensayos antiesclavistas de Cuba y Brasil, 1840-1880

La tesis doctoral presentada da cuenta de las "figuraciones de la esclavitud" en un amplio corpus textual (ensayos y novelas) de autores representativos de la "narrativa antiesclavista" en el siglo XIX, centrada en las áreas de Cuba y Brasil. Desde una perspectiva comparativa, que atiende a los planos retóricos y discursivos, se analizan puntualmente novelas y ensayos de autores canónicos como Gertrudis Gómez de Avellaneda, Cirilo Villaverde, José Antonio Saco, Alejandro von Humboldt, José de Alencar, Bernardo Guimaraes, Joaquim Nabuco y Jean-Baptiste Debret. A la vez, se incorpora la plasmación de un enfoque interdisciplinar en el análisis de la "narrativa antiesclavista", abordando también aspectos que remiten a la historiografía política, social y económica sobre el proceso de la esclavitud en el período de 1840-1880, junto con otros de articulación antropológica, cultural y estética en ambas zonas mencionadas
