A Study of Zolt\uc3\ua1n Kod\uc3\ua1ly's Sonata for Unaccompanied Violoncello, Op.8
The twentieth century was a period of non-stop innovation for western music. During that time Hungary also broke free of communism. It was because of under these circumstances which helped Kodaly developed his own style. Sonata for Unaccompanied Cello, Op. 8 in 1915 is one of Zolt\uc3\ua1n Kod\uc3\ua1ly\ue2s (1882-1967) earlier works. It contains influences of polyphonic style music from Giovanni Pierluigi da Palestrina and Johann Sebastian Bach as well as the inflections and nuances of Debussy and Hungarian folk music.
The article will focus on different perspectives of Kod\uc3\ua1ly\ue2s Sonata for Unaccompanied Cello, Op.8. It first gives a brief summary of Kodaly\ue2s historical background. Then it discusses the details and differences in tonality and modulation that has been used in this piece. Finally, the article will discuss performance technique focusing on both hands and preparation practices.
The writer wants to assist the reader whoever plays this piece in the future can easy to overcome any predicament in the music. Aside from technical aspects that Kodaly used, the author hopes the reader will understand the connotation and messages Kod\uc3\ua1ly tried to embody in Sonata for Unaccompanied Cello, Op. 8
Um arcabouço multimodal para geocodificação de objetos digitais
Orientador: Ricardo da Silva TorresTese (doutorado) - Universidade Estadual de Campinas, Instituto de ComputaçãoResumo: Informação geográfica é usualmente encontrada em objetos digitais (como documentos, imagens e vídeos), sendo de grande interesse utilizá-la na implementação de diferentes serviços. Por exemplo, serviços de navegação baseados em mapas e buscas geográficas podem se beneficiar das localizações geográficas associadas a objetos digitais. A implementação destes serviços, no entanto, demanda o uso de coleções de dados geocodificados. Este trabalho estuda a combinação de conteúdo textual e visual para geocodificar objetos digitais e propõe um arcabouço de agregação de listas para geocodificação multimodal. A informação textual e visual de vídeos e imagens é usada para definir listas ordenadas. Em seguida, elas são combinadas e a nova lista ordenada resultante é usada para definir a localização geográfica de vídeos e imagens. Uma arquitetura que implementa essa proposta foi projetada de modo que módulos específicos para cada modalidade (e.g., textual ou visual) possam ser aperfeiçoados independentemente. Outro componente é o módulo de fusão responsável pela combinação das listas ordenadas definidas por cada modalidade. Outra contribuição deste trabalho é a proposta de uma nova medida de avaliação da efetividade de métodos de geocodificação chamada Weighted Average Score (WAS). Ela é baseada em ponderações de distâncias que permitem avaliar a efetividade de uma abordagem, considerando todos os resultados de geocodificação das amostras de teste. O arcabouço proposto foi validado em dois contextos: desafio Placing Task da iniciativa MediaEval 2012, que consiste em atribuir, automaticamente, coordenadas geográficas a vídeos; e geocodificação de fotos de prédios da Virginia Tech (VT) nos EUA. No contexto do desafio Placing Task, os resultados mostram como nossa abordagem melhora a geocodificação em comparação a métodos que apenas contam com uma modalidade (sejam descritores textuais ou visuais). Nós mostramos ainda que a proposta multimodal produziu resultados comparáveis às melhores submissões que também não usavam informações adicionais além daquelas disponibilizadas na base de treinamento. Em relação à geocodificação das fotos de prédios da VT, os experimentos demostraram que alguns dos descritores visuais locais produziram resultados efetivos. A seleção desses descritores e sua combinação melhoraram esses resultados quando a base de conhecimento tinha as mesmas características da base de testeAbstract: Geographical information is often enclosed in digital objects (like documents, images, and videos) and its use to support the implementation of different services is of great interest. For example, the implementation of map-based browser services and geographic searches may take advantage of geographic locations associated with digital objects. The implementation of such services, however, demands the use of geocoded data collections. This work investigates the combination of textual and visual content to geocode digital objects and proposes a rank aggregation framework for multimodal geocoding. Textual and visual information associated with videos and images are used to define ranked lists. These lists are later combined, and the new resulting ranked list is used to define appropriate locations. An architecture that implements the proposed framework is designed in such a way that specific modules for each modality (e.g., textual and visual) can be developed and evolved independently. Another component is a data fusion module responsible for combining seamlessly the ranked lists defined for each modality. Another contribution of this work is related to the proposal of a new effectiveness evaluation measure named Weighted Average Score (WAS). The proposed measure is based on distance scores that are combined to assess how effective a designed/tested approach is, considering its overall geocoding results for a given test dataset. We validate the proposed framework in two contexts: the MediaEval 2012 Placing Task, whose objective is to automatically assign geographical coordinates to videos; and the task of geocoding photos of buildings from Virginia Tech (VT), USA. In the context of Placing Task, obtained results show how our multimodal approach improves the geocoding results when compared to methods that rely on a single modality (either textual or visual descriptors). We also show that the proposed multimodal approach yields comparable results to the best submissions to the Placing Task in 2012 using no additional information besides the available development/training data. In the context of the task of geocoding VT building photos, performed experiments demonstrate that some of the evaluated local descriptors yield effective results. The descriptor selection criteria and their combination improved the results when the used knowledge base has the same characteristics of the test setDoutoradoCiência da ComputaçãoDoutora em Ciência da Computaçã

Effects of low temperature storage and heat treatment on fruit qualities of
guava (Psidium guajava L.) were evaluated under controlled environmental
condition. Guava cultivars, ‘Li-Tzy Bar’, ‘Shyh-Jii Bar’, ‘Tai-Kuo Bar’ and
‘Jen-Ju Bar’, were used in the experiment. Symptom of chilling injury appeared
when fruits were stored at 1℃ or 5℃ for a period of 7-12 days and then placed at
20-25℃ for 3 to 4 more days. The symptoms of chilling injury were abnormal
ripening, pulp browning and water-soaking core in ‘Li-Tzy Bar’. In the case of
‘Shyh-Jii Bar’ only peel and pulp browning were observed. The water-soaking
core usually became visible at the terminal stage. Pulp browning emerged at an
early stage and then spreader to the peel of ‘Tai-Kuo Bar’ at 1℃ for 21 days.
Fruit of ‘Jen-Ju Bar’ exhibited only brown peel as well as water-soaking core.
This seemed to suggest that ‘Jen-Ju Bar’ was most chilling resistant, while
‘Tai-Kuo Bar’ was less tolerant. Cultivars such as ‘Shyh-Jii Bar’ and ‘Li-Tzy
Bar’ were found most sensitive to low temperature. In the mean time, the guava
fruit was individually wrapped up in a polyethylene bag under high humidity
condition with a view to reducing water loss and preventing sample from
shrinking
Wayfaring: Photography in Taiwan 1950s−1980s
Wayfaring: Photography in Taiwan, 1950s–1980s explores four transformative decades of photography in Taiwan, tracing its evolution amid the island’s emergence from Japanese colonialism and integration into Nationalist China, largely under martial law (1949–87). Through a dozen richly illustrated essays and interviews, the book bridges the gap between vigorous Chinese-language scholarship on photography in Taiwan and its limited representation in English. Essays on photographers in the 1950s–60s, including Long Chin-San (Lang Jingshan), Deng Nan-Guang, Chang Chao-Tang, Liu An-Ming, Huang Pai-Chi, Hsu Yuan-Fu and Tsai Hui-Feng, reveal photography’s pivotal role in documenting ‘local’ culture and shaping cultural identity, while challenging ideas of ‘amateur’ and ‘realist’ practices and recognising the importance of transnational connections. Meanwhile, essays on Hsu Jen-Shiu, Lin Bo-Liang, Kao Chung-Li, Lien Hui-Ling and Hou Tsung-Hui, along with interviews sharing the firsthand experiences of Liu Chen-Hsiang, Lulu Shur-tzy Hou and Yao Jui-Chung, highlight the experience of photography in 1970s–80s Taiwan, as both witness and agent of social transformation, addressing issues such as environmental protection, mental health and gender politics, as well as being a crucial vehicle for the transdisciplinary nature of contemporary art, theatre, cinema and performance in Taiwan at that time
Between a Rock and a Cell Phone: Social Media Use during Mass Protests in Iran, Tunisia and Egypt
In this paper we examine the use of social media, and especially Twitter, in Iran, Tunisia and Egypt during the mass political demonstrations and protests in June 2009, December 2010 - January 2011, and February 2011, respectively. We compare this usage with methods and findings from other studies on the use of Twitter in emergency situations, such as natural and man-made disasters. We draw on our own experiences and participant-observations as an eyewitness in Iran (first author), and on Twitter data from Iran, Tunisia and Egypt. In these three cases, Twitter filled a unique technology and communication gap at least partially. We summarize suggested directions for future research with a view of placing this work in the larger context of social media use in conditions of crisis and social convergence

番石榴果實褐化與乙烯之關係
本試驗調查番石榴幼果採收後果實褐化的發生與乙烯間之關係。'梨仔拔'和'水晶拔'幼果採收後果皮逐漸變暗,由深綠色轉變為紅褐色,且二品種皆具有假性更年性(Pseudo-climacteric)的現象,並出現乙烯高峰。但當乙烯釋放率明顯上升時,酚類化合則有下降之趨勢,再以AVG及l-MCP處理幼果皆無法有效抑制果實褐化,此結果顯示,幼果採收後的褐化可能和乙烯產生無直接相關。此外,幼果採收後酚類化合物有累積現象,可能由於新陳代謝加速,促進老化,造成細胞內胞器間膜之區隔作用消失,造成褐化反應,而使幼果產生褐化現象。The objectives of this experiment were to investigate the ethylene biosynthesis and browning reactions of harvested guava fruitlets. 'Shui-Jing' and 'Li-Tzy Bar' fruitlets after harvest possessed pseudo-climacteric phenomenon with apparent peak ethylene release and accompanied peel browning. Since AVG (inhibitor of ethylene biosynthesis) and 1-MCP (inhibitor of ethylene action) treatments had no alleviation effect indicating the browning of harvested fruitlets had nothing to do with ethylene per se. in addition, phenolic compound was accumulated of fruitlets after harvest. The results suggest that owing to high catabolism and senescence induced membrane breakdown and browing reactions of fruit let after harvested
Microblogging in Crisis Situations: Mass Protests in Iran, Tunisia, Egypt
In this paper we briefly examine the use of Twitter in Iran, Tunisia and Egypt during the mass political demonstrations and protests in June 2009, December 2010 and January 2011 respectively. We compare this usage with methods and findings from other studies on the use of Twitter in emergency situations, such as natural and man-made disasters. We draw on my own experiences and participant-observations as an eyewitness in Iran, and on Twitter data from Tunisia and Egypt. In these three cases, Twitter filled a unique technology and communication gap at least partially. We summarize suggested directions for future research with a view of placing this work in the larger context of social media use in conditions of crisis or social convergence.Presented at CHI 2011, May 7-12, Vancouver, Canad
