Shed Light on Leadership with Metaphor : How Chinese Leaders Integrate Themselves to Lead Better and even Lead beyond Domains

Jia, Yonglin January 2015 (has links)
Leadership has been studied from many angles. But in my study, I study leadership with metaphors, hoping to provide some new insights. With metaphors, I want to seek an answer what can leaders do to integrate themselves to lead better. In this time, leadership is no longer constrained within one domain. With rapid changes and merging among companies and industries, people expect leadership in a broader range of contexts and domains. I also want to find what leaders can do to manage their influence well, to get it across domains. I look into various fields including psychology, culture, leadership and others to gain knowledge. With the help of metaphor, I break the questions into answerable parts and start my research. As for methodology, I adopt systems approach. I conduct eight interviews with leaders from diversified backgrounds regarding age, gender, industry, position and family status. But one thing in common is that they are all highly engaged in multi-cultural or multi-domain interaction. By studying their experience, learning their past and their approach, I come up with eight patterns of influence from the interviews, showing their uniqueness in style and approach to integrate themselves and to convey influence beyond domains. In theoretical study, I further compare the patterns to locate the common parts and reveal the different parts. Then I introduce a concise frame and analyze further. Finally, by combining books, articles and analysis, I provide the advice on what leader can do to expand their influence. Finally, I suggest a few points for leaders to integrate themselves to be better leaders and seek their styles. Then, using their styles or patterns, develop and deliver their influence beyond domains.

O consórcio entre gramíneas e leguminosas pode ser uma estratégia interessante para aumentar os estoques de C e N e a quantidade forragem pelas pastagens cultivadas em sucessão, que resultarão em palhada para cobertura do solo no Sistema Plantio Direto (SPD). Em sucessão aos consórcios de verão, a aveia se torna uma opção importante, principalmente pela possiblidade de sobressemeadura, o que torna viável o seu cultivo por produtores que não tem acesso à semeadoras específicas para sementes miúdas. Objetivou-se com esse trabalho avaliar a produção de fitomassa aérea das espécies cultivadas, em função da presença ou não do feijão-guandu em consórcio com milho e capim marandú no verão para produção de silagem, e também em função das modalidades de semeadura da aveia-preta no outono-inverno para produção de pasto e palha, em SPD, com integração Lavoura-Pecuária (iLP), visando a terminação de cordeiros em semi-confinamento. Além disso, verificar se as emissões de gases de efeito estufa (GEE) por esses cultivos são compensados por aumentos no aporte de C no solo. A presente pesquisa foi realizada, na Fazenda Experimental Lageado, pertencente à Faculdade de Ciências Agronômicas – UNESP, localizada no município de Botucatu (SP), e foi conduzido nos anos agrícolas 2013/2014 e 2014/2015. O delineamento experimental foi em blocos casualizados, em parcela subdividida, com dois fatores (A e B) e 4 repetições. O fator A está alocado na parcela principal e constituído de dois tratamentos de verão, ou seja, duas modalidades de cultivo da cultura do milho para ensilagem, uma em consórcio com capim-marandu (Brachiaria brizantha (Hochst. ex A. Rich.) Stapf cv. Marandu [syn. Urochloa brizantha (Hochst. ex A. Rich.) R. D. Webster cv. Marandu] e a outra em consórcio com capim-marandu e feijão-guandu cv. BRS Mandarim. O fator B é alocado na subparcela e constituído de dois tratamentos de inverno, ou seja, duas modalidades de semeadura de aveia preta (Avena bysantina), uma a lanço (manual) e a outra em linha. Foi avaliado a qualidade e quantidade de silagem produzida, os teores de C e N no solo, o aporte sobre o solo de matéria seca, C e N pelos resíduos vegetais e os fluxos de gases de efeito estufa (CO2, N2O e CH4 provenientes do solo). Para comparação entre os tratamentos foi realizada análise de variância e as médias foram comparadas estatisticamente pelo teste t, no nível de 5 % de probabilidade de erro. As emissões de GEE foram maiores em outubro de 2014 logo após o pastejo, sendo o solo fonte de CH4. O cultivo do feijão-guandu resultou em maior aporte de resíduos vegetais sobre o solo, sendo esses resíduos com menor relação C/N. / Optionally for silage production, the intercrop of corn with the marandugrass and pigeon pea can increase the amount of produced silage, and this best quality. The consortium of grasses and legumes can be an interesting strategy to increase the stocks of C and N and the amount forage for pastures grown in succession, which will result in straw for mulching in no-tillage system. In succession to summer intercrop, oats becomes an important option, especially the possibility of overseeded, making it possible its cultivation by farmers who do not have access to specific seeders for small seeds. The objective of this study was to evaluate the air biomass production of cultivated species, depending on the presence or absence of pigeon pea intercropped with corn and pasture in the summer for silage, and also depending on the seeding arrangements for aveia- yellow in autumn-winter pasture production and straw in SPD with Crop-Livestock integration, aimed at terminating lambs in semi-confinement. Also, check if emissions of greenhouse gases (GHG) by these crops are offset by increases in the C input to soil.This survey was conducted in the Experimental Farm Lageado, belonging to the Faculty of Agricultural Sciences - UNESP, located in Botucatu (SP), and was conducted in the agricultural year 2014/2015. The experimental design is a randomized block in a split plot with two factors (A and B) and 4 repetitions, Factor A is allocated in the main plot and consists of two summer treatments, ie two crop cultivation modes corn for silage, one in consortium with marandugrass and the other in consortium with marandugrass and pigeon pea cv. BRS Mandarin. Factor B is allocated in the sub-plot and comprises two winter treatments, ie two types of hp yellow oat sowing. Sao Carlos (Avena bysantina) a broadcasted (manually) and the other in line. It was the quality and quantity of produced silage rated. The gas samples for determination of CO2 flows, N2O and CH4 from the soil were carried out after grazing oats, and during regrowth of braquiaria in 2014, during the grazing in 2014 was isolated an area within the plot, and shortly after the end of the grazing cycle were installed two chambers, 1 in the area that was not grazed. The second round of collection was after planting oats in 2015. Overall GHG emissions were higher in October 2014 soon after grazing, and the ground source of CH4, the desetos animals and quality and quantity of straw in influencied emissions. The treatments with a light harrowing for merger of oats, obtained the highest values of lower values of PPA.It was analyzed the stock of C and N in the 0-40 cm depth in the soil and plants and straw, to determine the balance of Generally the treatment with the legume submitted a C / N ratio smaller but with a greater contribution to the treatment plant without the legume. This sense labor objective was to evaluate the Greenhouse Gas Emissions Greenhouse in function of the use of different Systems Integration Crop Farming and as emissions of fluorinated gases can be compensated hair increase of C stocks in soil and straw with these practice managements. / FAPESP: 2013/23853-9

A pesquisa é de abordagem qualitativa e configura-se como um estudo de caso, realizado no Centro de Referência em Educação Infantil do Colégio Pedro II, com meninos e meninas de 3 a 6 anos, durante o período de março de 2014 a março de 2017. A partir de uma escuta sensível às vozes infantis, por meio de experiências sonoro-musicais e entrevistas realizadas, denominadas ConversAções, buscou-se investigar como a criança pequena constrói e percebe a Educação Musical no Colégio Pedro II e como se pode construir um projeto artístico educativo COM e A PARTIR dela. As discussões apresentadas foram conduzidas em forma de narrativa e abrigam as ideias musicais infantis de forma viva. O arcabouço teórico foi baseado em fundamentos filosóficos, educacionais, sociológicos e pedagógico-musicais, quais sejam: (a) uma proposta rizomática que construa uma rede de sentidos, com base no pensamento de Deleuze e Guattari; (b) uma escuta sensível à infância, apoiada nos estudos da Sociologia da Infância e na Pedagogia da Escuta das escolas Reggio Emília; (c) uma educação democrática, crítica, libertadora e construída pela comunidade escolar, baseada no pensamento de Paulo Freire e na proposta das escolas Reggio Emília; (d) a compreensão da música como arte, jogo, criação e fator de desenvolvimento humano, apoiada nos estudos da Companhia de Música Teatral – Portugal -, Rodrigues, Koellreutter, Brito, Schafer e Gainza. O diálogo entre a fundamentação teórica adotada e as vozes infantis permitiu a identificação de três bases para a construção e da educação musical da criança pequena em contexto escolar: brincar, integrar e criar. A pesquisa levou à compreensão dos meninos e meninas como sujeitos informantes competentes de pesquisa, copesquisadores, agentes criadores de cultura e coconstrutores da realidade. Por meio de experiências sonoro-musicais, envolvidas em contextos de brincadeira, integração e criação, as crianças transformam a si próprias, o outro, a escola e a sociedade em que estão inseridas. As discussões trazidas revelam a perspectiva de uma educação musical lúdica, integradora, criativa, democrática, social, cultural e humana. / Considering the challenges of mandatory music education in Brazil and the universalization of Early Childhood Education, this study aims to explore the idea of children and Music as transformation drivers.

Estudo da relação estrutura-dinâmica em redes modulares / Unveiling the relationship between structure and dynamics on modular networks

César Henrique Comin 26 April 2016 (has links)
Redes complexas têm sido cada vez mais utilizadas para a modelagem e análise dos mais diversos sistemas da natureza. Um dos tópicos mais estudados na área de redes está relacionado com a identificação e caracterização de grupos de nós mais conectados entre si do que com o restante da rede, chamados de comunidades. Neste trabalho, mostramos que comunidades podem ser caracterizadas por quatro classes gerais de propriedades, relacionadas com a topologia interna, dinâmica interna, fronteira topológica, e fronteira dinâmica das comunidades. Verificamos como estas diferentes características influenciam em dinâmicas ocorrendo sobre a rede. Em especial, estudamos o inter-relacionamento entre a topologia e a dinâmica das comunidades para cada uma dessas quatro classes de atributos. Mostramos que certas propriedades provocam a alteração desse inter-relacionamento, dando origem ao que chamamos de comportamento específico de comunidades. De forma a apresentarmos e analisarmos este conceito nos quatro casos considerados, estudamos as seguintes combinações topológicas e dinâmicas. Na primeira, investigamos o passeio aleatório tradicional ocorrendo sobre redes direcionadas, onde mostramos que a direção das conexões entre comunidades é o principal fator de alteração no relacionamento topologia-dinâmica. Aplicamos a metodologia proposta em uma rede real, definida por módulos corticais de animais do gênero Macaca. O segundo caso estudado aborda o passeio aleatório enviesado ocorrendo sobre redes não direcionadas. Mostramos que o viés associado às transições da dinâmica se tornam cada vez mais relevantes com o aumento da modularidade da rede. Verificamos também que a descrição da dinâmica a nível de comunidades possibilita modelarmos com boa acurácia o fluxo de passageiros em aeroportos. A terceira análise realizada envolve a dinâmica neuronal integra-e-dispara ocorrendo sobre comunidades geradas segundo o modelo Watts-Strogatz. Mostramos que as comunidades podem possuir não apenas diferentes níveis de ativação dinâmica, como também apresentar diferentes regularidades de sinal dependendo do parâmetro de reconexão utilizado na criação das comunidades. Por último, estudamos a influência das posições de conexões inibitórias na dinâmica integra-e-dispara, onde mostramos que a inibição entre comunidades dá origem a interessantes variações na ativação global da rede. As análises realizadas revelam a importância de, ao modelarmos sistemas reais utilizando redes complexas, considerarmos alterações de parâmetros do modelo na escala de comunidades. / There has been a growing interest in modeling diverse types of real-world systems through the tools provided by complex network theory. One of the main topics of research in this area is related to the identification and characterization of groups, or communities, of nodes more densely connected between themselves than with the rest of the network. We show that communities can be characterized by four general classes of features, associated with the internal topology, internal dynamics, topological border, and dynamical border of the communities. We verify that these characteristics have direct influence on the dynamics taking place over the network. Particularly, for each considered class we study the interdependence between the topology and the dynamics associated with each network community. We show that some of the studied properties can influence the topology-dynamics interdependence, inducing what we call the communities specific behavior. In order to present and characterize this concept on the four considered classes, we study the following combinations of network topology and dynamics. We first investigate traditional random walks taking place on a directed network. We demonstrate that, for this dynamics, the direction of the edges between communities represents the main method for the modification of the topology-dynamics relationship. We apply the developed approach on a real-world network, defined by the connectivity between cortical regions in primates of the Macaca genus. The second studied case considers the biased random walk on undirected networks. We demonstrate that the transition bias of this dynamics becomes more relevant for higher network modularity. In addition, we show that the biased random walk can be used to model with good accuracy the passenger flow inside the communities of two airport networks. The third analysis is done on a neuronal dynamics, called integrate-and-fire, applied to networks composed of communities generated by the Watts-Strogatz model. We show that the considered communities can not only posses distinct dynamical activation levels, but also yield different signal regularity. Lastly, we study the influence of the positions of inhibitory connections on the integrate-and-fire dynamics. We show that inhibitory connections placed between communities can have a non-trivial influence on the global behavior of the dynamics. The current study reveals the importance of considering parameter variations of network models at the scale of communities.

Implementing virtual sets in a 2D environment : A study in how to efficiently integrate 3D virtual sets with photos

Nilsson, David January 2010 (has links)
In this paper I’ll be investigating how to implement and use virtual 3D sets using only simple 2D reference footage. There are many possible ways to achieve similar effects but I’ll be specifically targeting the lower end segment of the industry by using methods that require fewer resources. Other methods are used in large film productions in Hollywood but my goal with this paper is to make the technology more accessible for small-scale companies and productions.

Parameter Estimation, Optimal Control and Optimal Design in Stochastic Neural Models

Iolov, Alexandre V. January 2016 (has links)
This thesis solves estimation and control problems in computational neuroscience, mathematically dealing with the first-passage times of diffusion stochastic processes. We first derive estimation algorithms for model parameters from first-passage time observations, and then we derive algorithms for the control of first-passage times. Finally, we solve an optimal design problem which combines elements of the first two: we ask how to elicit first-passage times such as to facilitate model estimation based on said first-passage observations. The main mathematical tools used are the Fokker-Planck partial differential equation for evolution of probability densities, the Hamilton-Jacobi-Bellman equation of optimal control and the adjoint optimization principle from optimal control theory. The focus is on developing computational schemes for the solution of the problems. The schemes are implemented and are tested for a wide range of parameters.

Modelling and Verifying Dynamic Properties of Neuronal Networks in Coq

Bahrami, Abdorrahim 08 September 2021 (has links)
Since the mid-1990s, formal verification has become increasingly important because it can provide guarantees that a software system is free of bugs and working correctly based on a provided model. Verification of biological and medical systems is a promising application of formal verification. Human neural networks have recently been emulated and studied as a biological system. Some recent research has been done on modelling some crucial neuronal circuits and using model checking techniques to verify their temporal properties. In large case studies, model checkers often cannot prove the given property at the desired level of generality. In this thesis, we provide a model using the Coq proof assistant and prove some properties concerning the dynamic behavior of some basic neuronal structures. Understanding the behavior of these modules is crucial because they constitute the elementary building blocks of bigger neuronal circuits. By using a proof assistant, we guarantee that the properties are true in the general case, that is, true for any input values, any length of input, and any amount of time. In this thesis, we define a model of human neural networks. We verify some properties of this model starting with properties of neurons. Neurons are the smallest unit in a human neuronal network. In the next step, we prove properties about functional structures of human neural networks which are called archetypes. Archetypes consist of two or more neurons connected in a suitable way. They are known for displaying some particular classes of behaviours, and their compositions govern several important functions such as walking, breathing, etc. The next step is verifying properties about structures that couple different archetypes to perform more complicated actions. We prove a property about one of these kinds of compositions. With such a model, there is the potential to detect inactive regions of the human brain and to treat mental disorders. Furthermore, our approach can be generalized to the verification of other kinds of networks, such as regulatory, metabolic, or environmental networks.
