Hybridations inter-spécifiques chez le pommier et co-évolution hôte-pathogène / Inter-specific hybridizations in apple trees and host-pathogen co-evolutionFeurtey, Alice 29 November 2016 (has links)
Dans une première partie de mon projet de thèse, je me suis intéressée aux hybridations interspécifiques et à l’histoire évolutive des espèces de pommiers en Europe. L’analyse de génomes complets m’a permis de confirmer que l’ancêtre du pommier cultivé est bien le pommier sauvage asiatique M. sieversii, mais aussi que de nombreuses variétés cultivées originaires de l’Europe forment un groupe génétique distinct de cette espèce sauvage. Ces variétés montrent des traces d’introgressions par le pommier sauvage européen M. sylvestris et une structuration de populaton selon un axe est-ouest. Les introgressions depuis le pommier cultivé sont également abondantes dans les populations de pommier sauvage européen M. sylvestris, et menacent leur intégrité génétique. Les niveaux des introgressions étaient corrélés aux activités anthropiques d’exploitation des pommiers et les hybrides n’avaient pas de réduction détectable de valeur sélective sur les caractères mesurés. Notre étude de la phylogéographie du pommier sauvage européen dans l’ensemble de son aire de distribution nous a permis de détecter des groupes génétiques différenciés résultant de l’histoire climatique passée de la planète. Ces groupes représentent autant d’unités de conservation différentes.Dans une seconde partie, j'ai étudié la coévolution entre espèces de plantes et espèces de champignons pathogènes dans deux systèmes différents. Je me suis tout d'abord intéréssée à l’histoire évolutive combinée des pommiers cultivés et sauvages d’Asie centrale et du champignon causant la tavelure, Venturia inaequalis. Dans les montagnes du Kazakhstan, le pommier cultivé a été réintroduit au cours des deux derniers siècles, créant une zone de contact secondaire, non seulement entre M. domestica et M. sieversii, mais aussi entre les populations de V. inaequalis de types agricole et sauvage. Alors que l’invasion des populations sauvages par le pommier cultivé semble encore limité géographiquement, le pathogène de type agricole est largement répandu dans les forêts et sur l’hôte sauvage. Cependant, le nombre d’hybrides détectés chez le pathogène reste limité, probablement en raison de barrières intrinsèques à la reproduction, puisque les deux types de pathogènes infectent les mêmes arbres hôtes. Dans un second temps, j’ai comparé les structures génétiques et spatiales à l’échelle européenne de la plante Silene latifolia et de son pathogène Microbotryum lychnidis-dioicae. Notre jeu de données constitué du génotype d’un pathogène et de la plante qu’il infectait nous a permis de comparer la structure à très fine échelle et celle-ci apparait remarquablement congruente. Trois groupes phylogéographiques ont été identifiés chez les deux organismes, correspondant à l’histoire de contraction-expansion des aires de distribution des espèces tempérées lors de la dernière glaciation. Une structure génétique plus fine a également été détectée chez le pathogène, suggérant la possibilité d’une histoire plus complexe. / In the first part of my thesis project, I studied the evolutive history of apple tree species in Europe, including interspecific hybridizations. Analyses of whole genome data confirmed that the progenitor species of the cultivated apple tree was M. sieversii, a Central Asia wild apple tree, but also that a high proportion of European cultivated varieties form a genetic group distinct from the wild species. These varieties show traces of introgressions from M. sylvestris and of population subdivision along an East-West axis. Microsatellite markers also showed that introgressions from the cultivated apple were also quite frequent in wild apple tree populations and thus threaten their genetic integrity. We found that introgression levels were correlated to anthropic activities of apple tree cultivation and gave rise to hybrids with no detectable reduced fitness on the traits measured. Our study of the European wild apple tree phylogeography allowed us to detect differentiated genetic groups resulting from the past climatic history of the planet and which should be considered as different evolutionary significant units in conservation.In the second part of my thesis project, I studied coevolution between plant species and their pathogenic fungi in two different systems. I first compared the evolutive history of cultivated and wild apple trees in Central Asia and that of their scab pathogen, Venturia inaequalis. In the Kazakhstan Mountains, the cultivated apple tree has been reintroduced back from Europe during the last two centuries. This created a secondary contact zone, not only between the two apple tree species, but also between the agricultural and the wild types of V. inaequalis. While the invasion of natural populations by the cultivated apple trees still seems geographically limited, the agricultural pathogen is widespread in the forests and on the wild host trees. However, the number of hybrids in the pathogen was limited, probably because of intrinsic reproductive barriers since no ecological barriers were found. I also compared spatial genetic structures at the European scale in the plant Silene latifolia and its anther-smut pathogen Microbotryum lychnidis-dioicae. Our dataset included genotypes from the pathogens and the plants on which they were collected, and the population structures appeared remarquably congruent. Three phylogenetic groups were identified in these both species, corresponding with the temperate species range contraction-expansion cycles during the past glaciations. A substructure was identified in the pathogen suggesting the possibility of a more complex history.

Distributed collaboration on RDF datasets using GitArndt, Natanael, Radtke, Norman, Martin, Michael 23 June 2017 (has links)
Collaboration is one of the most important topics regarding the evolution of the World Wide Web and thus also for the Web of Data. In scenarios of distributed collaboration on datasets it is necessary to provide support for multiple different versions of datasets to exist simultaneously, while also providing support for merging diverged datasets. In this paper we present an approach that uses SPARQL 1.1 in combination with the version control system Git, that creates commits for all changes applied to an RDF dataset containing multiple named graphs. Further the operations provided by Git are used to distribute the commits among collaborators and merge diverged versions of the dataset. We show the advantages of (public) Git repositories for RDF datasets and how this represents a way to collaborate on RDF data and consume it. With SPARQL 1.1 and Git in combination, users are given several opportunities to participate in the evolution of RDF data.

Adaptation of the Romanomermis culicivorax CCA-Adding Enzyme to Miniaturized Armless tRNA SubstratesHennig, Oliver, Philipp, Susanne, Bonin, Sonja, Rollet, Kévin, Kolberg, Tim, Jühling, Tina, Betat, Heike, Sauter, Claude, Mörl, Mario 10 January 2024 (has links)
The mitochondrial genome of the nematode Romanomermis culicivorax encodes for
miniaturized hairpin-like tRNA molecules that lack D- as well as T-arms, strongly deviating from
the consensus cloverleaf. The single tRNA nucleotidyltransferase of this organism is fully active on
armless tRNAs, while the human counterpart is not able to add a complete CCA-end. Transplanting
single regions of the Romanomermis enzyme into the human counterpart, we identified a beta-turn
element of the catalytic core that—when inserted into the human enzyme—confers full CCA-adding
activity on armless tRNAs. This region, originally identified to position the 30
-end of the tRNA
primer in the catalytic core, dramatically increases the enzyme’s substrate affinity. While conventional
tRNA substrates bind to the enzyme by interactions with the T-arm, this is not possible in the case of
armless tRNAs, and the strong contribution of the beta-turn compensates for an otherwise too weak
interaction required for the addition of a complete CCA-terminus. This compensation demonstrates
the remarkable evolutionary plasticity of the catalytic core elements of this enzyme to adapt to
unconventional tRNA substrates.

[pt] MODELO DE NEURO CO-EVOLUÇÃO COM INSPIRAÇÃO QUÂNTICA APLICADO A PROBLEMAS DE COORDENAÇÃO / [en] QUANTUM INSPIRED NEURO CO-EVOLUTION MODEL APPLIED TO COORDINATION PROBLEMSEDUARDO DESSUPOIO MOREIRA DIAS 19 November 2021 (has links)
[pt] Em diversos problemas encontrados na literatura, se faz necessária alguma coordenação entre os agentes para que a tarefa seja realizada de forma ótima. Entretanto, pode ser difícil a obtenção desta coordenação por conta da quantidade e características dos agentes, dinâmica do ambiente e/ou complexidade da tarefa. O objetivo principal deste estudo é propor um modelo que possa se adaptar a problemas heterogêneos de coordenação e de dimensões elevadas, com aprendizado autônomo e que tenha convergência satisfatória, o qual foi denominado Modelo de Neuro Co-Evolução com Inspiração Quântica (NCoQ). O modelo se utiliza dos paradigmas da física quântica e da co-evolução biológica, evoluindo concomitantemente sub-populações de indivíduos quânticos para obter ganhos de convergência. A representação dos indivíduos por pulsos quânticos consegue reduzir o número de indivíduos em cada população, além de ser a mais recomendada para a utilização de neuro-evolução por conta da representação real. Ressalta-se também a capacidade do modelo em obter de forma autônoma a melhor configuração de arquitetura para as redes neurais de cada agente, não exigindo do programador a escolha deste parâmetro. Foram propostos novos operadores quânticos de crossover e mutação que foram comparados na otimização de funções de diversas dimensões. Para testar o desempenho do modelo, foram desenvolvidas, em linguagem MATLAB, simulações para o problema presa predador, para o benchmark multi-rover de exploração de ambientes e uma simulação para cobertura telefônica. Foram feitas comparações com outros modelos neuro-evolutivos encontrados na literatura, tendo o modelo NCoQ apresentado os melhores resultados. / [en] Many problems in the literature require some coordination among agents so a specific task can be executed more efficiently. However, this coordination can be difficult because of the quantity and characteristics of the agents, environment dynamics and/or task complexity. The main contribution of this Thesis is the proposal of a model, called Quantum Inspired Neuro Co-Evolution (NCoQ), that can adapt to heterogeneous multi-agent problems in high dimensions utilizing self-learning and that has satisfactory convergence. The model is inspired in quantum physics and biological co-evolution paradigms and evolves concomitantly subpopulations of quantum individuals to get convergence gains. The representation of individuals for quantum functions is able to reduce the numbers of individuals in each population and it is the most recommended for real neuro-evolution representation. It s also important to point out the model capacity in self-finding the best architecture of the neural networks agents, not requiring an a priori definition of this parameter. New crossover and mutation quantum operators were also proposed and compared in functions optimization of multiple dimensions. To test the model performance, three MATLAB simulations were developed: prey-predator task, multi-rover task and cell phone coverage area simulation. Comparisons were made against others neuro-evolution models found in literature and the NCoQ model attained the best results.

Phylogeny and evolution of a highly diversified catfish subfamily : the Loricariinae (Siluriformes, Loricariidae) / Phylogénie et évolution d’une sous-famille très diversifiée de poissons-chats : les Loricariinae (Siluriformes, Loricariidae)Covain, Raphaël 15 September 2011 (has links)
Les Loricariinae appartiennent à la famille des poissons-chats néotropicaux cuirassés Loricariidae, la famille de poissons-chats la plus riche en espèce au monde, et se caractérisent par un pédoncule caudal long et aplati et par l’absence de nageoire adipeuse. Préalablement aux études évolutives réalisées, une phylogénie exhaustive et robuste a été établie sur la base de données mitochondriales et nucléaires. Cette phylogénie a ensuite été utilisée dans des analyses multivariées et multi-tableaux afin de révéler les principales tendances évolutives de la sous-famille. La phylogénie obtenue indique que la tribu Harttiini forme un groupe paraphylétique et est restreinte à trois genres, et que dans la tribu Loricariini, deux sous-tribus soeurs se distinguent, les Farlowellina et les Loricariina, chacune présentant des patterns évolutifs complexes. Plusieurs nouveaux taxa ont aussi été mis en évidence et décrits. En utilisant la phylogénie comme outil exploratoire, nous avons démontré : (1) avec l’analyse de co-inertie que les caractères diagnostiques fournis pour définir les différents genres étaient sous dépendance phylogénétique ; (2) avec l’analyse de co-inertie multiple que les forces évolutives sous-jacentes dirigeant leur diversification incluaient des composantes intraphénotypiques (morphologie et génétique) et extraphénotypique (écologie et distribution) ; (3) avec l’analyse RLQ que des évènements de co-dispersion entre espèces codistribuées avaient eu lieu et étaient responsables de la distribution actuelle des espèces ; et (4) avec l’analyse de patterns multi-échelles que la co-évolution des traits liés aux caractéristiques de la bouche était liée à des fonctions reproductrices responsables d’une évolution tertiaire de cet organe. / The Loricariinae belong to the Neotropical mailed catfish family Loricariidae, the mostspeciose catfish family in the world, and are united by a long and flattened caudal peduncle and the absence of an adipose fin. Despite numerous works conducted on this group, no phylogeny is presently available. Prior to conduct evolutionary studies, an exhaustive and robust phylogeny was reconstructed using mitochondrial and nuclear data. Then, this phylogeny was used in multivariate and multi-table analyses to reveal the main evolutionary trends of the subfamily. The resulting phylogeny indicated that the Harttiini tribe, as classically defined, formed a paraphyletic assemblage and was restricted to three genera, and within the Loricariini tribe, two sister subtribes were distinguished, Farlowellina and Loricariina, both displaying complex evolutionary patterns. In addition several new taxa were highlighted and described. Subsequently using this phylogeny as exploratory tool, we demonstrated: (1) using co-inertia analysis that the diagnostic features provided to define the different genera were phylogenetically dependent; (2) using multiple co-inertia analysis that the underlying evolutionary forces shaping their diversification included intraphenotypic (morphology and genetics) and extraphenotypic (ecology and distribution) components; (3) using the RLQ analysis that co-dispersion events occurred between co-distributed species responsible for the current fish distribution; and (4) using the multi-scale pattern analysis that the co-evolution in traits related to the mouth characteristics was linked to reproductive functions responsible for a tertiary evolution of this organ.

Previous issue date: 2015-04-30 / This study has as main objective to analyze whether the financial organizations and interacted significantly influenced the regulatory institutions producing changes or adjustments to the conditions of the banking environment due to the sharing of knowledge and information on the regulation and international prudential supervision, the Basel Accord. It is a qualitative research, justified by the complexity of the phenomenon and the multiple aspects involved which would hardly be captured by quantitative approaches. The method used is the only case study with in-depth interviews and content analysis for collection and processing of information. The theoretical lens is the institutional co-evolution, as a theory with dynamic perspective when considering that in the interactive process between organizations, institutions and the environment, the agents adapt to distinct and independent ways forward to new conditions. Changes in regulation may be attached to strategic maneuvers of financial organizations in the search for development of the environment, is innovating instruments and influencing the other participants or articulating cooperation actions. In this regard, we look at how the international regulation influenced local organizations and how these, in the process of interaction with the regulator, eventually influenced changes in the banking environment. It was observed that developments in the regulatory and supervisory spheres (preventive prudential measures) occurred before adverse scenarios of the global economy where organizations anticipated regulatory changes that would allow them leeway and greater conservatism in the face of external crises scenarios. Examples of best management practices, more dynamic governance and pricing instruments coming from the international market led to strategic changes in the organizational field, to adapt the organization to the environmental context and the strategic changes of choices that resulted in strong and influential interaction, individual and deliberate or collective response to threats and opportunities perceived, with other market organizations and the regulator through technical cooperation and exchange of knowledge, influencing strategic practices of interest to leading organizations and their stakeholders. / Este estudo tem como objetivo geral analisar se as organizações financeiras interagiram e influenciaram significativamente as instituições regulatórias produzindo mudanças ou ajustes nas condições do ambiente bancário razão do compartilhamento de conhecimento e informações sobre a regulação e supervisão prudencial internacional, o Acordo de Basiléia. Trata-se de uma pesquisa qualitativa, justificada pela complexidade do fenômeno e os múltiplos aspectos envolvidos os quais dificilmente seriam capturados por abordagens quantitativas. O método utilizado é o estudo de caso único, com entrevistas em profundidade e análise de conteúdo para coleta e tratamento das informações. A lente teórica é a co-evolução institucional, por ser uma teoria com perspectiva dinâmica ao considerar que no processo interativo entre organizações, instituições e o ambiente, os agentes se adaptam de maneiras distintas e independentes frente às novas condições. Mudanças na regulação podem ser associadas às manobras estratégicas das organizações financeiras na busca por evolução do ambiente, seja inovando instrumentos e influenciando os demais participantes ou articulando ações de cooperação. Neste sentido, analisa-se como a regulação internacional influenciou as organizações locais e como estas, no processo de interação com o regulador, acabaram por influenciar mudanças no ambiente bancário. Observou-se que a evolução nas esferas de regulação e supervisão (medidas prudenciais preventivas) ocorreu diante de cenários adversos da economia global, onde organizações anteciparam mudanças regulatórias que lhes permitissem margem de manobra e maior conservadorismo diante de cenários de crises externa. Os exemplos de melhores práticas de gestão, governança e de instrumentos de precificação mais dinâmicos vindos do mercado internacional geraram mudanças estratégicas no campo organizacional, de adaptação das organizações ao contexto do ambiente e das escolhas de mudanças estratégicas que resultaram em forte e influente interação, individual e deliberada ou resposta coletiva às ameaças e oportunidades percebidas, com outras organizações do mercado e com o regulador através de cooperação técnica e troca de conhecimento, influenciando práticas estratégicas de interesse de organizações líderes e seus stakeholders.

Previous issue date: 2005-05-12 / nenhum / This dissertation has the object to discuss the role of cultural journalism in the construction of Guaíra Theater s image as being the exclusive representative of all dance production in Paraná State. For that, it has reunited as corpus of its investigation the published material of local news paper s and for some of national circulation between 1956 and 2004. With that, intending to attest that was this printed media action, in municipal, state and national levels, that constructed and consolidated a type of entail that goes back to the creation of Guaíra Theater Ballet Course, in 1956. And that was done on account of coevolutive current agreements in that environment. The hypothesis that has guided the investigation of the nature of this entail has its fundaments in a semiotics approach of the Evolutive Theories. The investigation was based on the understanding that were certain memes that propagated in linked processes to contamination and influence that, even today set Curitiba s dance environment. The dissertation maps the context in which the entail was established, identifying the prioritary aspects in the formation of this lasting association. This dissertation also discourses about the forms of using the government budget to the dance in Paraná and the aim is to contribute to a necessary public debate about the relation between the communication channels and public politics. Based on the Coevolution concept, this dissertation concludes that some survival strategies still remain in the city s environment, showing its replicators strength and the importance of evaluating these theories, searching direction for future choices to the formulation of public politics to the dance in the city. / Esta dissertação tem como objeto discutir o papel do jornalismo cultural na construção da imagem do Teatro Guaíra como sendo o representante exclusivo de toda a produção de dança do Estado do Paraná. Para tal, reuniu como corpus de investigação o material publicado pelos jornais locais e por alguns de circulação nacional entre 1956 e 2004. Com ele, pretende atestar que foi a ação desta mídia impressa, em nível municipal, estadual e nacional, que construiu e consolidou um tipo de vínculo que remonta à criação, em 1956, do Curso de Ballet do Teatro Guaíra. A hipótese que guiou a investigação da natureza desse vínculo se fundamenta em uma abordagem semiótica das Teorias Evolutivas. A investigação pautou-se pelo entendimento de que foram certos memes que se propagaram em processos atrelados à contaminação e também à influência e que, ainda hoje, montam o ambiente da dança em Curitiba. A dissertação mapeia o contexto em que o vínculo se estabeleceu, identificando quais os aspectos prioritários na formação desta associação tão duradoura. Discorre-se também sobre as formas de uso da verba pública para a dança no Paraná e visa-se contribuir para um debate público sobre a relação entre canais de comunicação e políticas públicas. Baseando-se no conceito de Coevolução, conclui-se que algumas estratégias de sobrevivência permanecem no ambiente, demonstrando a força de seus replicadores, e a importância de se avaliar estes mecanismos à luz de conceitos abarcados por estas Teorias, buscando nortear futuras escolhas para formulação de políticas públicas para a dança na cidade.

資源基礎、跨組織間知識共同演化行為與創新績效之研究 / The study of Resource Base, Inter-organizational Kowledge Co-evolutionary Behavior and Innovation Performance方亮淵, Fang,Liang-Yuan Unknown Date (has links)
從理論而言,本論文企圖從生態演化的觀點,針對組織與組織間,或事業體與事業體間,觀察組織是否具有同生物物種間共同演化的現象,並從組織知識與學習的觀點,探討組織與組織間知識共同演化的行為機制與其對創新績效的關係。過去的文獻中,針對組織或事業體間之策略與績效間的關係,多數均從多角化的觀點出發,探討組織、市場或產品間的相關度,來預測績效的成果,但從資源基礎的角度觀察實務的現象,組織間的資源基礎,並非均可在組織間自由的流動或轉移,組織亦非只單純依賴於相關度高的其他事業組織才足以創造績效。因此,組織如何與其他的事業體組織進行資源的移轉以創造策略績效,特別是對於創新績效相關的知識資源,在現今的理論及文獻中,並沒有特別的加以探討。本研究針對此一研究的缺口,乃試圖利用生態學說之共同演化的觀點,奠基於Eisenhardt and Galunic(2000)之共同演化策略的文獻作出發點,來探討組織與組織間知識共同演化的行為機制,以及其對組織創新績效的影響。
經由文獻的探討與先導個案的觀察,本研究提出了主要的研究架構,在資源基礎構面上,本研究觀察了自我組織與其他對偶組織間三種資源:實體設備資源、技術知識資源、網絡關係資源;而在知識屬性構面上,本研究提出了領域相似性及功能互補性二個子構面,而在應變數創新績效上,本研究則觀察組織的創新件數、創新件數變動率及創新產業競爭力;創新績效類別上則觀察組織四種創新類型:產品創新、製程創新、技術創新以及市場創新等四個組織績效。而針對調節變數上,本研究則著由文獻歸納及個案觀察發展出組織間知識共同演化的四個行為構面:交互學習吸收、自我學習強化、相關變異適應與共有例規保留。藉由此四個構面所發展出的行為子構面題項問卷,本研究可以觀察組織與組織間知識共同演化行為的強度,以作為影響組織間資源基礎與組織創新績效關係的調節變數。
本研究藉由質性之個案研究法之先導個案─長興化工的觀察,發展出量化之問卷調查法之研究問卷,並針對潤泰企業集團之營建事業體與紡織事業體共十四個事業組織,二十八位受訪者進行實證研究,調查此十四個事業組織間所構成之364個對偶關係之組織關係,一一進行問卷調查及記錄。並依據此十四個事業組織受訪者問卷,進行數值分析及多變量分析工作。本研究係採用SPSS統計分析工具。
經由問卷統計分析的結果,本研究得到研究成果及結論如下:
1. 從資源基礎論的觀點,對於組織的創新績效,除自我組織的實體設備、技術知識及網絡關係資源有正向助益效果外,組織的資源亦可跨越組織疆界的概念,延伸至組織生態系統中其他對偶組織之資源基礎的層次。
2. 組織與其生態系統中其他對偶組織間的知識共同演化行為活動愈強,對偶組織之實體設備資源、技術知識資源及網絡關係資源,愈有助於組織之創新績效表現
2-1.自我組織與其他對偶組織間的交互學習吸收行為愈強,對偶組織之資源基礎愈有助於組織創新績效表現。
2-2.自我組織與其他對偶組織間的自我學習強化行為愈強,對偶組織之資源基礎愈有助於組織創新績效表現。
2-3.自我組織與其他對偶組織間的相關變異適應行為愈強,對偶組織之資源基礎愈有助於組織創新績效表現。
3. 組織與對偶組織間之知識屬性不同,其彼此間之知識共同演化行為的強度亦有所不同。知識領域相似性愈高,功能互補性愈高的組織,其知識共同演化的四個構面(交互學習吸收、自我學習強化、相關變異適應及共有例規保留)行為強度均較強。
4. 具有深度知識共同演化行為的事業部組織,其在創新的件數及創新的產業競爭力上,表現均會較其他中度知識共同演化或低度知識共同演化的事業部組織來得佳,且在新產品創新、新製程創新及新技術創新等方向上,與其他事業部具有深度知識共同演化的事業部組織,其創新績效較佳。 / The research, based on the evolutionary theory, tries to find is there any kind of the co-evolution relationship between organizations or business-units. Starting from the organization knowledge management and organizational learning, the research studies the co-evolution behavior mechanism between dyad organizations and also studies the impact of the knowledge co-evolution behavior on innovation performance.
Reviewing the research which study the strategy and performance mechanism between organizations or business units, lot of them use the diversification point of view to propose the market relatedness or the product relatedness are important on estimating the performance of organization, especially the new market that organization will enter. The researcher finds there is a theatrical gap between the resource transferability of dyad organizations and innovation performance creating. However, based on the research of Eisenhardt and Galunic (2000), the research will use the evolutionary theory to study how organization adopting the knowledge resource from another organization to create organization innovation performance.
The research concept structure proposed by the research will have four constructs. The first one, in resource based construct, this research propose three kinds of resource in self-organization and dyad organization: (1) tangible resource and asset in practice facility; (2) intangible resource and asset in technical knowledge; (3) network resource and asset between organizations. The second construct is the knowledge attribute. This research proposes two kind of attribute between organizations, (1)similarity of field knowledge and (2) complementarity of functional knowledge. In the dependent construct, the research proposes innovation performance in innovation success cases, innovation growth and competence of product innovation, technical innovation, process innovation and market innovation. In the final construct of moderator variable, the research propose four dimensions of the knowledge co-evolutionary mechanism: (1) knowledge learning and absorbing; (2) knowledge combining and creating; (3) knowledge adapting on relative variance; (4) practicing on mutual organization routine.
The methodologies of the research are case study and questionnaire interview and analyze. We review 14 organizations of textile division and civil engineering divisions of Ruentex Group. After analyzing the questionnaire of 28 interviewers, the research generates four conclusions as below:
(1) From the resource-based view, not only the resource of self-organization could have positive benefit on the performance of organization innovation, but also the resource from dyad organization could contribute on innovation performance. The concept of organization resource could break through the organization boundary and extend to the dyad organization in the same organizational environment.
(2) The more knowledge co-evolutionary behavior, the more benefit of inter-organizational resource will have on innovation performance.
A. The more knowledge learning and absorbing on co-evolutionary behavior, the more benefit of inter-organizational resource will have on innovation performance.
B. The more knowledge combining and creating on co-evolutionary behavior, the more benefit of inter-organizational resource will have on innovation performance.
C. The more knowledge adapting on relative variance on co-evolutionary behavior, the more benefit of inter-organizational resource will have on innovation performance.
(3) The knowledge attribute of the two dyad organizations will effect on the degree of the knowledge co-evolutionary behavior. The higher the similarity of field knowledge and complementarity of functional knowledge, the heavier the inter-organizational knowledge co-evolutionary behavior.
(4) The innovation performance of the organization which have heavier knowledge co-evolutionary behavior will better then the ones have medium or lighter knowledge co-evolutionary behavior, especially on the product innovation, process innovation and technical innovation performance.
