Consensus decisions in self-organizing systems / Consensus decision making process in self-organizing teamsLe Borgne, Lucas January 2022 (has links)
Self-organization is a management concept that has been implemented in different forms since the XIXth century. However, it seems that this particular model of management rediscovers increasing popularity. Indeed, various companies across the globe have transformed their systems to weaken the hierarchy and empower their workers. I explore the subject of consensus decision process in decentralized systems, and more precisely the context in which such a decision process takes place. To analyze the context of decision making-process in self-organizing teams, I suggest a model composed of three theories: the polycentric governance of Ostrom, the specific capital of Bourdieu, and the communicative action of Habermas. These three theories are gathered in a model composed of three levels of analysis. The integrative level uses the polycentric governance theory to analyze the overarching structure of rules that backbones a system. The distributive level studies the distribution of power and influence among the workers of the system. And the interactive level studies the characteristics of the discussion which ends on consensus with the help of the communicative action theory. Then, the model is composed of three levels that are studied through the analysis of 9 patterns highlighted in the literature review. The model is tested on a case study. I carry out interviews to analyze the decision-making context of the company Menlo Innovation, which has implemented a non-hierarchical management model. The analysis of the company shows that the model is useful to study context of decision-making. However, another level of analysis empirically came up. Patterns that did not fall in any of the existing levels of analysis have been empirically highlighted, and form together a new level of analysis: the cultural policy. Given the appearance of this new level, the model has been adapted to form a new framework composed of 4 areas interconnected that are studied through the analysis of 12 patterns. The thesis contributes to the existing knowledge in several ways. First, it provides a promising model of analysis for context of consensus decision making in selforganizing systems. Second, it brings a new understanding of the centrality of the specific capital distribution in nonhierarchical organizations. Finally, it highlights a new dimension of analysis for self-organization.

Self-Organizing Fluid Flow Patterns in Crystalline Rock: Theoretical Approach to the Hydrothermal Systems in the Middle Fork of the Boise RiverHimes, Scott A. 25 July 2012 (has links) (PDF)
The thermal springs along the Middle Fork of the Boise River (MFBR) within the Atlanta lobe of the Idaho batholith discharge in discrete locations that appear to be part of self-organizing flow systems. Infiltrating water flows through Basin and Range fractures to depth where it is heated and ultimately discharged at the intersection of trans-Challis oriented faults along the MFBR. Isotopic compositions of the thermal waters have a linear trend with elevation suggesting that the recharge locations are near each thermal spring and the hydrothermal system is not one large interconnected system, but rather multiple individual hydrothermal systems. Water chemically evolves along the hydrothermal flow paths dissolving feldspars and precipitating secondary minerals. PHREEQC inverse modeling of the chemical evolution based on identified minerals within the system predicts positive volume changes in the pore space within the hydrothermal flow systems can occur. Precipitation of secondary minerals is likely to occur in the cooler, subsidiary, less-efficient fractures of the hydrothermal system. Flow areas calculated using heat flow, exponential decay, and a combination of the two, show that the topographic watershed is inadequate to accommodate the water supporting the thermal springs indicating that water is being captured from outside the watershed. The positive volume changes coupled with the water capture is evidence of positive feedback loops are active within the hydrothermal system providing a mechanism for self-organization to occur in the hydrothermal systems of granite.

Learning Companions motivierend gestaltenSchlimbach, Ricarda, Karaban, Vladislav, Robra-Bissantz, Susanne 31 May 2023 (has links)
In einer zunehmend digitalen und sich rasant verändernden Arbeitswelt, wird lebenslanges Lernen immer wichtiger für den beruflichen Erfolg (OECD, 2021). Technologische Entwicklungen und der Trend zum digitalen Lernen und Arbeiten, schaffen neue Möglichkeiten für die berufsbegleitende Weiterbildung.... Learning Companions (LCs), also digitale, natürlich-sprachige Agenten (Chatbots oder sprachbasierte Assistenten), die eine freundschaftsähnliche Beziehung zu ihrem menschlichen Nutzer aufbauen, stellen einen innovativen Lösungsansatz dar, um Menschen vielfältig, individualisiert sowie zeit- und ortsunabhängig beim Lernen zu unterstützen (Khosrawi-Rad et al., 2022). Da eine hohe Motivation einen positiven Effekt auf den Lernerfolg und dessen Nachhaltigkeit hat (Hawlitschek & Merkt, 2018), jedoch gleichzeitig, insbesondere im digitalen Raum ein großes Problemfeld darstellt (Limarutti et al., 2021), forcieren wir den Einsatz eines LCs in seiner Rolle als Motivator.

Semantic Service management for service-oriented MASDel Val Noguera, Elena 08 March 2013 (has links)
Actualmente, los sistemas informáticos complejos se describen en términos de entidades que actúan como proveedores y consumidores. Estas entidades ofrecen su funcionalidad a través de servicios e interactúan entre ellas para ofrecer o pedir estos servicios. La integración de Sistemas Multi-Agente Abiertos y de Sistemas Orientados a Servicios es adecuada para implementar este tipo de sistemas. En los SMA abiertos, los agentes entran y salen del sistema, interactúan con los demás de una manera flexible, y se consideran como entidades reactivas y proactivas, capaces de razonar acerca de lo que sucede en su entorno y llevar a cabo acciones locales sobre la base de sus observaciones para alcanzar sus metas. El área de la computación orientada a servicios proporciona los bloques de construcción básicos para aplicaciones empresariales complejas que son los servicios. Los servicios son independientes de la plataforma y pueden ser descubiertos y compuestos de manera dinámica. Estas características hacen que los servicios sean adecuados para hacer frente a la elevada tasa de cambios en las demandas de las empresas.
Sin embargo, la complejidad de los sistemas informáticos, los cambios en las condiciones del entorno y el conocimiento parcial de los agentes sobre el sistema requieren que los agentes cuenten con mecanismos que les faciliten tareas como el descubrimiento de servicios, la auto-organización de sus relaciones estructurales conforme se producen cambios en la demanda de servicios, y la promoción y mantenimiento de un comportamiento cooperativo entre los agentes para garantizar el buen desarrollo de la actividad de descubrimiento de servicios en el sistema.
La principal aportación de esta tesis doctoral es la propuesta de un marco para Sistemas Multi-Agente Abiertos Orientados a Servicios. Este marco integra agentes que se encuentran en una red sin ningún tipo de estructura predefinida, y agentes que además de estar en esa red forman parte de grupos dinámicos más comp / Del Val Noguera, E.

Integrating driving forces into the development of Adaptive Virtual OrganizationsEsparcia García, Sergio 31 March 2015 (has links)
Organizations have become the backbone of the society. Humans live around
all kinds of organizations, such as neighborhood communities, businesses, schools,
unions, political, sports, and religious organizations, etc. These organizations have
a set of members, each playing a specific role, which determines their duties and
functionalities within the organization. One of these functionalities is to offer a
range of services to members of the organization and external people. These members
must follow a set of norms to ensure the proper functioning of the organization
and should pursue the global goals of the organization.
A feature that is repeated in organizations is that they are not static but
dynamic, resulting in changes in both its structure and the way in which they
behave. In an organization, any of its elements is prone to change due to situations
that occur in the organization itself or its environment. Researchers in the field
of social sciences and organizations have studied such situations, the reasons why
they appear and solutions and actions to be taken to ensure that this situation
does not damage the organization or to take advantage of the situation. These
situations are known as ‘Forces that drive organizational change’.
Human organizations are the main source of inspiration for the Multi-Agent
Systems (MAS) based on organizations. These systems are computational abstractions
that are populated by agents instead of people, but take into account
organizational elements such as roles, services, goals, norms, etc. However, the
proposals that have been presented up to now to define this type of MAS are focused
mostly on static systems, without changes in its structure. Moreover, in the
few proposals that take into account organizational changes, they just state that
changes occur, but without specifying the reason for change. Thus, the concept of
‘forces that drive organizational change’ (and their features) is not considered.
Therefore, the objective of this PhD thesis is to translate the knowledge of the
forces that drive organizational change available in human organizations to MASbased
organizations. These forces will be formally expressed with the factors that
help to detect them. The solutions to be taken when a force is detected will also
be presented. To correctly perform this task, a formalization for virtual organizations
is designed, named Virtual Organization Formalization (VOF). Moreover,
the Artifacts for Organizational Mechanisms are proposed, which are a tool to
help in the representation of organizational knowledge and in the modeling of the
environment of the organization. This tool is based on the Agents & Artifacts
(A&A) framework. / Esparcia García, S. (2015). Integrating driving forces into the development of Adaptive Virtual Organizations [Tesis doctoral]. Universitat Politècnica de València. https://doi.org/10.4995/Thesis/10251/48538

Self-organized quantum wires on patterned GaAs(311)A and on unpatterned GaAs(100)Ma, Wenquan 24 October 2001 (has links)
In der vorgelegten Arbeit wurden zwei Arten von Quantendrahtstrukturen untersucht, die mittels Molekularstrahlepitaxie (MBE) hergestellt wurden. Erstens ist dies eine laterale Quantendrahtstruktur, die sich entlang einer Mesakante durch selektives Wachstum auf strukturierten GaAs (311)A-Substraten ausbildet. Zunächst wurden vertikal gestapelte Quantendrähte mit starker elektronischer Kopplung realisiert. Weiterhin wurden, unter Nutzung des amphoteren Einbaus von Si, p-i-n-Leuchtdioden mit einem einzelnen Quantendraht in der aktiven Zone hergestellt, die sich durch selektive Ladungsträgerinjektion in die Quantendrähte auszeichnen. Die Leuchtdioden wurden weitergehend mittels Mikrophotolumineszenz(µ-PL), Kathodolumineszenz (CL) und Elektronenstrahl-induziertem Strom (EBIC) charakterisiert. Zur Erklärung der selektiven Elektrolumineszenz (EL) wurde ein Modell, basierend auf der lateralen Diffusion von Elektronen und Löchern, vorgeschlagen. Für verspannte Systeme wurde der Einfluss von atomarem Wasserstoff auf das Wachstum von (In,Ga)As auf GaAs (311)A und die Bildung von lateralen Quantendrähten untersucht. Atomarer Wasserstoff spielt dabei die Rolle eines Surfaktanden und unterdrückt deutlich die Bildung von dreidimensionalen Inseln. Zweitens wurde das Wachstum von verspannten (In,Ga)As-Schichten auf GaAs (100) untersucht. Es zeigte sich, dass die dreidimensionale Inselbildung durch die Wachstumskinetik bestimmt ist, und ein Übergang von symmetrischen zu asymmetrisch verlängerten Inseln bei Erhöhung der Wachstumstemperatur auftritt. Dieser Prozess wird durch das Zusammenspiel von Oberflächen- und Verspannungsenergie bestimmt, wobei die experimentellen Befunde in guter Übereinstimmung mit den theoretischen Arbeiten von Tersoff und Tromp sind. Ausgehend von asymmetrischen (In,Ga)As-Inseln wurden selbstorganisierte Quantendrähte hergestellt, deren Homogenität und Länge sich durch Wachstum einer Vielschichtstruktur deutlich erhöhen. Strukturell wurden die (In,Ga)As-Quantendrähte mittels Rasterkraftmikroskopie (AFM), Röntgendiffraktometrie (XRD) und Transmissionselektronenmikroskopie (TEM) untersucht. Der laterale Ladungsträgereinschluss in den Quantendrähten zeigte sich deutlich in polarisationsabhängigen Photolumineszenz- und Magnetophotolumineszenzmessungen. / The present work focuses on two types of quantum wire structures which were grown by molecular beam epitaxy (MBE). First, the sidewall quantum wires based on the selective growth on mesa stripe patterned GaAs(311)A are studied. Single stacked sidewall quantum wires with strong electronic coupling have been fabricated. p-i-n type LEDs of the quantum wires employing the amphoteric Si incorporation for p- and n-type doping on GaAs(311)A have been fabricated. Strong selective carrier injection into the quantum wires is observed in electroluminescence (EL) measurements. The samples are characterized by micro-photoluminescence (µ-PL), cathodoluminescence (CL), as well as electron beam induced current (EBIC) measurements. To account for the highly selective EL, a model is proposed, which is based on the lateral diffusion of electrons and holes resulting in self-enhanced carrier injection into the quantum wires. Atomic hydrogen effects in the growth of (In,Ga)As on GaAs(311)A and its application to the sidewall quantum wire are investigated. It is found that atomic hydrogen suppresses island formation. Atomic hydrogen delays the relaxation by islanding thus playing the role of a surfactant. Second, the growth of (In,Ga)As layers on GaAs(100) is investigated showing that the formation of coherent 3D islands is a kinetically limited process. The transition from square-shaped islands to elongated islands is observed by changing the growth temperature for the growth of (In,Ga)As single layers. The elongation of the islands is a tradeoff between the surface free energy and the strain energy. A quantitative comparison between the experimental results and the theoretical work done by Tersoff and Tromp shows a good agreement. Self-organized quantum wires based on elongated discolation-free islands have been fabricated. The uniformity of the quantum wires is greatly improved by a superlattice growth scheme which also makes the wires much longer. The structural characterization of the quantum wires is performed by atomic force microscopy (AFM), x-ray diffractometry (XRD), and transmission electron microscopy (TEM). The lateral carrier confinement in the quantum wires is confirmed by polarization dependent PL and magneto-PL measurements.

概念型創新的動態擴散過程--複雜理論觀點王美雅, Wang, Mei-ya Unknown Date (has links)
許多新概念或新技術的擴散通常不僅耗時甚長、擴散範圍十分廣泛,再加上社會網路在其中扮演了重要的角色,使得創新擴散本質上就屬於一種動態、非線性的複雜現象,事實上,近來研究發現,創新擴散的諸多特徵,包括「動態、非線性的複雜行為」,「正向回饋的自我組織現象」,以及「對初始狀態一些微小因素的敏感度」等,都與複雜理論中所強調「複雜系統」中的諸多特徵不謀而合。
另一方面,近來創新擴散研究逐漸將擴散視為一個創新者與採用者雙向互動的傳播過程,在擴散過程中,創新的演化與成員間的動態互動成為主要焦點。過去的擴散研究較少討論個體與總體層次間的結構化過程,亦即成員如何互動而產生系統層次的創新秩序,而系統層次的創新結果又如何進一步影響成員的互動,而複雜理論正好可以提供跨層次架構來回應此一理論缺口。
因此,本論文的研究問題包括以下兩者:一、由複雜理論觀點來看,概念型創新擴散的動態過程為何?二、由複雜觀點來看,在概念型創新的擴散過程中,相關因素如何影響創新擴散的動態過程?這些因素間存在何種互動與回饋關係?承上所述,本研究的範圍界定為「概念型創新」,在此「概念型創新」指的是近似於典範的一種具有複雜多元內涵的創新。
在研究方法上,本論文採用序列性多元方法的研究設計。利用歷史法、實驗法與個案法三種研究方法,針對相同的兩項問題,總共進行三項實證性研究,透過「質性方法--量化方法--質性方法」三種研究方法的截長補短,提高本研究的理論效度。
研究一利用歷史研究法對蒙特梭利教學法的擴散過程進行研究,將蒙特梭利教學法的擴散分為三階段,透過三階段成功、失敗與成功三種不同結果,發現不同的初始狀態變數情況,主要是再創造可能性與體制開放與自由度,將導致創新擴散的不同結果。研究二新概念擴散實驗進行兩階段實驗設計,操弄五項自變數進行重複多因子實驗,共取得二十八個實驗數據;比較不同變數情境與採用結果,除了驗證初始狀態變數對創新擴散的影響外,也發現自變數間存在明顯的交互關係。研究三進行蝴蝶蘭產業創新擴散個案研究,比較台糖進入蝴蝶蘭產業前後的創新擴散過程,以及蝴蝶蘭、嘉德利雅蘭,以及國蘭三種蘭屬的發展過程。隨著三項實證研究的進行,變數內涵逐漸豐富化,證據力也進一步強化。在研究三結束後得到修正後的觀念性架構,成為本論文的結論。
在結論部分,本研究有三大主張。首先,系統的初始狀態,包括創新導入者的網路位置、體制自由與開放性、再創造可能性、創新內涵豐富性、擴散誘因與採用人數等六項因素,將影響創新擴散成功的可能性。其次,創新擴散過程中包含許多的演化與正向回饋機制。最後,創新擴散是一個自我組織的過程,系統秩序從低一層次成員之間的互動自然突現,而非走向無序;但在自我組織過程中,秩序的出現有賴於中央協調機制(標準版本);同時系統需要不斷輸入的能源,使其維持在自我組織行為出現的臨界點之上,這些能源通常來自於新採用者所帶來的量與質的效果。 / This dissertation applies a new perspective, complexity theory, to discuss the diffusion of “conceptual innovation”. Here conceptual innovation indicates a paradigm-like innovation with various content. By using “metaphor”, I treat diffusion as a self-organization process, and adopted important concepts from complexity theory, such as initial conditions, positive feedback, and self-organization, and then develop a dynamic process model of innovation diffusion.
In this dissertation, a multi-method research design is adopted. To draw on the strength of each and offset the weakness of the others, three empirical studies were conducted. First study, the pilot study of this dissertation, is concerning the diffusion process of Montessori method, in which the different result of three diffusion stages was compared. Second, a laboratory experimental study simulating diffusion process of a new concept has been conducted. In each experiment, a new concept was announced and counted the number of adopters. Each experiment has different scenario design that is one specific combination of all variables, and then the number of adopters was compared. Third, the diffusion process of Phalaenopsis (Moth Orchid) industrial innovations was studied, in which the development process of early/late stage and three category orchids was compared.
This dissertation concludes with the following findings. First, innovation diffusion is a dynamic, nonlinear complex process; factors in initial conditions will influence the result of innovation diffusion. Secondly, evolution and positive feedback effects work continuously all through the diffusion process. Finally, diffusion of conceptual innovation is a self-organization process, which depends on energy injecting into the system continuously and the existence of central coordination mechanism in the system.
