The organizational ecology of ethnic cleavages: The nonlinear effects of ethnic diversity on party system fragmentation

The conventional wisdom regarding party system fragmentation assumes that the effects of electoral systems and social cleavages are linear. However, recent work applying organizational ecology theories to the study of party systems has challenged the degree to which electoral system effects are linear. This paper applies such concepts to the study of social cleavages. Drawing from theories of organizational ecology and the experience of many ethnically diverse African party systems, I argue that the effects of ethnic diversity are nonlinear, with party system fragmentation increasing until reaching moderate levels of diversity before declining as diversity reaches extreme values. Examining this argument cross-nationally, the results show that accounting for nonlinearity in ethnic diversity effects significantly improves model fit.

The transformation of a health care system: An ecology perspective

Beginning in the early 1980s, the health care system experienced momentous realignments. Fundamental changes in structures of traditional health care organizations, shifts in authority and relationships of professionals and institutions, and the increasing influence of managed care contributed to a relatively stable industry entering into a state of turbulence. The dynamics of these changes are recurring themes in the health services literature. The purpose of this dissertation was to examine the content of this literature over a defined time period and within the perspective of a theory of organizational change. ^ Using a theoretical framework based upon the organizational theory known as Organizational Ecology, secondary data from the period between 1983 and 1994 was reviewed. Analysis of the literature identified through a defined search methodology was focused upon determining the manner in which the literature characterized changes that were described. Using a model constructed from fundamentals of Organizational Ecology with which to structure an assessment of content, literature was summarized for the manner and extent of change in specific organizational forms and for the changes in emphasis by the environmental dynamics directing changes in the population of organizations. Although it was not the intent of the analysis to substantiate causal relationships between environmental resources selected as the determinants of organizational change and the observed changes in organizational forms, the structured review of content of the literature established a strong basis for inferring such a relationship. ^ The results of the integrative review of the literature and the power of the appraisal achieved through the theoretical framework constructed for the analysis indicate that there is considerable value in such an approach. An historical perspective on changes which have transformed the health care system developed within a defined organizational theory provide a unique insight into these changes and indicate the need for further development of such an analytical model. ^

Depredación organizacional

El concepto de depredación en el ámbito de la organización es comúnmente asociado al deterioro de sus recursos, pero al abordarlo desde la ecología de poblaciones, el resultado es un enfoque centrado en las relaciones entre los actores de la organización y la interacción de tres variables principales: el poder de los actores, la intimidad entre ellos y la letalidad de sus actuaciones; estas dos últimas solicitadas en préstamo desde la clasificación funcional propuesta por la ecología de poblaciones y claves en la relación presa-depredador. El documento presenta una aproximación para aprovechar estos conocimientos disponibles en la ecología y argumenta que su estudio facilita la comprensión de los estilos de estrategia y dirección en la organización.

Estudio de las interacciones intra-específicas (la competición, la cooperación y la depredación) en las organizaciones: revisión de literatura

Las organizaciones son un ente social y económico que según la teoría clásica debe ser vista como una estructura administrativa. Para Mooney (1947) existen principios los cuales baso en la teoría organización, en donde busca establecer relaciones entre principios, procesos y efectos. Por lo que el satisfacer las necesidades de una población debe ser un proceso que involucre intereses particulares .En este caso la organización debe ser estudiada y evaluada como un sistema que tiene diferentes jerarquías y agentes que interactúan entre si, para cumplir un objetivo. Las relaciones que se generan dentro de una organización, y en este caso una organización privada tienden a dar respuesta a muchas necesidades que como procesos se presentan en el diario vivir; es así como se habla del éxito de las organizaciones basado en la competitividad que generan las habilidades y actitudes del personal, el número de variables, fenómenos y efectos, que busca que los empleados asuman actitudes que conlleven a tomar buenas decisiones (Garcia, 2009 ). Es importante resaltar en las organizaciones, los fenómenos de liderazgo, poder e influencia, cada concepto independiente pero visto conjuntamente desde un panorama organizacional, donde toda relación intraespecifica deben determinarse en los diferentes comportamientos, conductas y culturas del personal de la empresa (Fuentes, 2004). La depredación, competencia y cooperación, son conceptos que indudablemente están presentes en todos los procesos de la organización y serán determinantes en la perdurabilidad de la misma. Por último, la presente investigación pretende establecer los efectos de los fenómenos sociales de liderazgo, poder e influencia sobre las interacciones intra-especificas (competencia, cooperación y depredación) al interior de una organización, de tal manera que se logre explicar el efecto y la correlación que existe entre unos y otros fenómenos (Castro, 2012).

Caracterización de la competencia entre dos organizaciones del sector de seguros en Colombia

En la permanente búsqueda de mejores condiciones que las organizaciones realizan con el propósito de dar respuesta a los cambios del entorno y la complejidad de la interacción con las organizaciones del mismo sector, se encuentra necesario identificar las características que les permiten a estas, sobrevivir, mantenerse en el mercado o crecer en él. En este orden de ideas, en este documento se desarrolla la caracterización de la forma como dos organizaciones importantes y líderes del sector asegurador en Colombia: Seguros Bolívar y Suramericana de Seguros, compiten, desde el punto de vista comercial, con el propósito de identificar como esto influye en cada organización. La investigación se centró en explicar a partir de los autores revisados y analizados con respecto al concepto de la competencia, en particular, la forma como se enfrenta la organización al entorno tanto interno como externo, la influencia de cada organización según su estructura, su importancia, la disponibilidad de los recursos necesarios para desarrollar sus actividades, el impacto y las implicaciones organizacionales a partir de la forma cómo se enfrenta el entorno. Para lo anterior y con base a la revisión conceptual, se realizó la recolección de datos y cifras tanto de las organizaciones como del sector al cual pertenecen, adicionalmente se realizaron entrevistas tanto estructuradas como semi estructuradas al área de ventas, debido a que es el área de las organizaciones encargada de generar estrategias de ventas, posicionar productos en el mercado, identificar el perfil del consumidor, conocer y comprender el mercado y la competencia. Lo anterior con el fin de caracterizar a las organizaciones analizadas, determinando cómo responden a la competencia y al entorno, para finalmente establecer cuáles son los comportamientos recurrentes, similares y diferentes entre ellas. Por lo tanto, los resultados obtenidos en la investigación permiten establecer si dos empresas con estructuras, tamaño y participación en el mercado similares compiten de igual forma y que implicación tiene esto en el comportamiento organizacional.

Resistance is futile: the borg, the hive, and corporate hegemony

The Borg, a collective of humanoid cyborgs linked together in a hive-mind and modeled on the earthly superorganisms of ant colonies and beehives, has been the most feared alien race in the Star Trek universe. The formidable success of the Borg in assimilating their foes corresponds to the astounding success of superorganisms in our own biosphere. Yet the Borg also serves as a metaphor for another collective of biological entities known as the corporation. In the Anthropocene epoch, corporations have become the most powerful force on the planet; their influence on the social world and the environment exceeds any government and may determine the continued sustainability of human life. Corporations have been described as people and as machines, but neither metaphor accurately describes their essence or contributes to an understanding that might resist their power. This paper reframes our understanding of the corporation by examining the metaphors that are used to describe it, and by suggesting an entirely new metaphor viewing the Borg and the corporation through the lens of sociobiology. I will argue that the corporation is a new form of superorganism that has become the dominant species on the planet and that the immense, intractable power of a globalized, corporate hive-mind has become the principal obstacle to addressing the planetary emergency of climate change. Reframing our metaphoric understanding of corporations as biological entities in the planetary biosphere may enable us to imagine ways to resist their increasing dominance and create a sustainable future. 

Polymorphic toxin systems: Comprehensive characterization of trafficking modes, processing, mechanisms of action, immunity and ecology using comparative genomics

Background: Proteinaceous toxins are observed across all levels of inter-organismal and intra-genomic conflicts. These include recently discovered prokaryotic polymorphic toxin systems implicated in intra-specific conflicts. They are characterized by a remarkable diversity of C-terminal toxin domains generated by recombination with standalone toxin-coding cassettes. Prior analysis revealed a striking diversity of nuclease and deaminase domains among the toxin modules. We systematically investigated polymorphic toxin systems using comparative genomics, sequence and structure analysis. Results: Polymorphic toxin systems are distributed across all major bacterial lineages and are delivered by at least eight distinct secretory systems. In addition to type-II, these include type-V, VI, VII (ESX), and the poorly characterized "Photorhabdus virulence cassettes (PVC)", PrsW-dependent and MuF phage-capsid-like systems. We present evidence that trafficking of these toxins is often accompanied by autoproteolytic processing catalyzed by HINT, ZU5, PrsW, caspase-like, papain-like, and a novel metallopeptidase associated with the PVC system. We identified over 150 distinct toxin domains in these systems. These span an extraordinary catalytic spectrum to include 23 distinct clades of peptidases, numerous previously unrecognized versions of nucleases and deaminases, ADP-ribosyltransferases, ADP ribosyl cyclases, RelA/SpoT-like nucleotidyltransferases, glycosyltranferases and other enzymes predicted to modify lipids and carbohydrates, and a pore-forming toxin domain. Several of these toxin domains are shared with host-directed effectors of pathogenic bacteria. Over 90 families of immunity proteins might neutralize anywhere between a single to at least 27 distinct types of toxin domains. In some organisms multiple tandem immunity genes or immunity protein domains are organized into polyimmunity loci or polyimmunity proteins. Gene-neighborhood-analysis of polymorphic toxin systems predicts the presence of novel trafficking-related components, and also the organizational logic that allows toxin diversification through recombination. Domain architecture and protein-length analysis revealed that these toxins might be deployed as secreted factors, through directed injection, or via inter-cellular contact facilitated by filamentous structures formed by RHS/YD, filamentous hemagglutinin and other repeats. Phyletic pattern and life-style analysis indicate that polymorphic toxins and polyimmunity loci participate in cooperative behavior and facultative 'cheating' in several ecosystems such as the human oral cavity and soil. Multiple domains from these systems have also been repeatedly transferred to eukaryotes and their viruses, such as the nucleo-cytoplasmic large DNA viruses. Conclusions: Along with a comprehensive inventory of toxins and immunity proteins, we present several testable predictions regarding active sites and catalytic mechanisms of toxins, their processing and trafficking and their role in intra-specific and inter-specific interactions between bacteria. These systems provide insights regarding the emergence of key systems at different points in eukaryotic evolution, such as ADP ribosylation, interaction of myosin VI with cargo proteins, mediation of apoptosis, hyphal heteroincompatibility, hedgehog signaling, arthropod toxins, cell-cell interaction molecules like teneurins and different signaling messengers.

The brain in business:the case for organizational cognitive neuroscience?

The application of cognitive neuroscientific techniques to understanding social behaviour has resulted in many discoveries. Yet advocates of the ‘social cognitive neuroscience’ approach maintain that it suffers from a number of limitations. The most notable of these is its distance from any form of real-world applicabity. One solution to this limitation is ‘Organisational Cognitive Neuroscience’ – the study of the cognitive neuroscience of human behaviour in, and in response to, organizations. Given that all of us will spend most of our lives in some sort of work related organisation, organisational cognitive neuroscience allows us to examine the cognitive underpinnings of social behaviour that occurs in what may be our most natural ecology. Here we provide a brief overview of this approach, a definition and also some possible questions that the new approach would be best suited to address.

Networking for conservation: social capital and perceptions of organizational success among land trust boards

As an important component in collaborative natural resource management and nonprofit governance, social capital is expected to be related to variations in the performance of land trusts. Land trusts are charitable organizations that work to conserve private land locally, regionally, or nationally. The purpose of this paper is to identify the level of structural and cognitive social capital among local land trusts, and how these two types of social capital relate to the perceived success of land trusts. The analysis integrates data for land trusts operating in the U.S. south-central Appalachian region, which includes western North Carolina, southwest Virginia, and east Tennessee. We use factor analysis to elicit different dimensions of cognitive social capital, including cooperation among board members, shared values, common norms, and communication effectiveness. Measures of structural social capital include the size and diversity of organizational networks of both land trusts and their board members. Finally, a hierarchical linear regression model is employed to estimate how cognitive and structural social capital measures, along with other organizational and individual-level attributes, relate to perceptions of land trust success, defined here as achievement of the land trusts’ mission, conservation, and financial goals. Results show that the diversity of organizational partnerships, cooperation, and shared values among land trust board members are associated with higher levels of perceived success. Organizational capacity, land trust accreditation, volunteerism, and financial support are also important factors influencing perceptions of success among local, nonprofit land trusts.
