Digital Capability : Investigating Coevolution of IT and Business Strategies / Digital abilitet : En undersökning av samevolution mellan IT- och affärsstrategier

Sandberg, Johan January 2014 (has links)
This dissertation investigates the role of information technology (IT) in organizational strategy. Specifically, it examines how organizations can persist in turbulent competitive landscapes characterized by IT innovations. Underlying premises for this dissertation are that: (1) ubiquitous IT implies constant disruptions from digital innovation, (2) IT and practice are becoming fused, and (3) organizational strategies are dynamically linked with practice, i.e. they are reciprocally related through what organizations do rather than have. To investigate such IT strategizing processes, I outline a conceptual framework for analyzing how organizations can generate digital capability, i.e. a collection of routines for strategizing by leveraging digital assets to create differential value. Digital assets here refer to the complement of available resources and competencies for IT design and implementation. Based on the notion of dynamic capability and evolutionary theory, this framework emphasizes the importance of sensing, seizing and transforming abilities for generating digital capability. As organizational practices are becoming fused with IT scholars have argued that attempting to disentangle them analytically is futile. In a similar vein, organizational strategy is increasingly reliant on available IT resources for both formulation and execution. In the IS field it is widely acknowledged that IT has both enabling and inhibiting consequences for organizations. Drawing on the resource-based view of the firm and theory on organizational capabilities, the notion of IT capability has been widely used as a conceptual tool for analyzing these dual strategic effects of IT. Considering the explosive advances in computing, network and interaction that have resulted in IT being ubiquitous and deeply embedded in contemporary practices, recent research argues for the need to move beyond the functional view of technology implicit in the IT capability notion. A key aspect to address for such broadening of the perspective is the coevolution of IT and business practices, i.e. who (or what) leads, who or what follows, and whether such a causal distinction is meaningful. Grounded in the outlined conceptual framework, this dissertation examines how organizations can build digital capability to both enable large variation and complexity of feasible competitive actions, and reduce inhibiting effects of IT. The empirical investigation is situated in three distinct domains: boundary spanning IT innovation, transformation of existing IT resources, and hybridization of technology through digitalization of production equipment. These investigations are presented in five research papers. The dissertation contribute to knowledge of IT strategy by: (1) explicating the construct of digital capability, (2) providing a framework for coevolutionary strategizing processes, (3) presenting an empirical illustration of the coevolution of IT and business strategies, and (4) offer specific insights on design and orchestration of processes for digital capability generation.

An investigation into the acoustic behaviour, ecology, biogeography, genetic relatedness and species limits within the Pauropsalta annulata Goding and Froggatt species complex (Hemiptera: Cicadidae)

Lindsay Popple Unknown Date (has links)
This thesis investigates aspects of the ecology, morphology, bioacoustics, genetic relatedness, biogeography and taxonomy of cicadas in the Pauropsalta annulata Goding and Froggatt species complex, across their entire eastern Australian geographical distribution. These cicadas seem to emerge at the same sites annually, although the exact duration of their life cycle is not known. They are wary and mobile insects, with individuals generally taking flight at the first sign of disturbance, which makes them challenging to record, capture and observe. The males produce distinctive calling songs that have a consistent rhythmic structure, which is critically important for attracting females. In most cases, the songs are biphasic, with a penetrating introductory or "buzzing" component that apparently functions in mate attraction and a strongly structured cueing or "lilting" component for mate localisation. Initially Pauropsalta annulata was thought to comprise a single species with some degree of geographically structured variation in its calling song. Consequently, various "song types" had been recognised, but their precise relationship to one another had never been investigated. Therefore the structure of their calling songs were compared statistically across individuals of three song types, and this revealed four discrete clusters that were demonstrated to be independent of one another and consistent in their calling song structure. Plotting the geographical distributions of these cicadas revealed that each of the P. annulata song types is independently distributed geographically, with areas of overlap that are relatively small. Calling song structure is consistent for each song type across extensive geographical space and this structure holds even into areas of sympatry. One song type showed consistent differences from the others in male genitalia structure, and female ovipositor length differs significantly among three of the other song types. Each song type was found to be strongly associated with a small number of tree species and these associations are maintained into areas of sympatry. The spatial ecological and morphological comparisons in song structure, plant associations and morphology made in this study demonstrate that the P. annulata song types actually represent a complex of cryptic species. Two of the song types appear to intergrade in areas of sympatric overlap in terms of calling songs, plant associations and morphology, and thus represent subspecies as defined in population genetics terms. The components of the male calling song were then investigated to determine their specific functions and thus how they could delimit species boundaries. Significant differences were found in dominant song frequency between three of the four species, and may contribute to differential mate attraction. Both components of the song of each species have the same dominant frequency. Consistent differences were also evident, among species and subspecies, in the rhythmic structure of the "lilting" component of the male calling song. This component contains repeated phrases and each one of these provides a cue to which the conspecific female may respond. Her response is timed for the brief silent interval between the phrases. At this point the calling song becomes a duet, which enables the male to locate the female, as he actively searches for her on the surrounding branches at this stage. The calling song is discussed in terms of random mating within gene pools of these cicadas and in terms of its role as part of their broader fertilisation mechanism. A molecular analysis of the P. annulata species complex was performed to examine the phylogenetic relationships across 12 species and four subspecies defined in this study, and estimate divergence times within the group. Individual specimens were sampled widely across the geographical distributions of the species and subspecies where possible to account for genetic variation across space. DNA sequences from two loci were amplified: mitochondrial CO1 ("barcoding region") and a large intron from the dynamin nuclear gene. Separate phylogenies were reconstructed for each locus using maximum parsimony procedures and Bayesian posterior sampling with implementation of a relaxed molecular clock. The phylogenies from both genes provided strong support for the monophyly of the P. annulata species complex, and nine of the species were monophyletic based on the CO1 gene. The remaining three emerged non-monophyletic. Based on a clock calibration of 0.0165s/s/myr, the monophyletic clades represented by extant P. annulata species diverged about 4.5-8.0 million years ago. Those species that emerged non-monophyletic had shallower divergences, with the exception of one species, which exhibited haplotype diversity that conferred up to 13.2% sequence divergence between allopatric populations in CO1. Dynamin produced a broadly similar phylogenetic pattern to that of CO1, but the relationships among individuals across the species and subspecies that emerged non-monophyletic differed substantially. This lack of congruence between the two genomes, in combination with the dominance of internal haplotypes in both loci, indicates an overall pattern of deep coalescence rather than interspecific hybridization. Therefore the molecular data do not provide an alternative definition of species limits in the P. annulata species complex, despite some emerging non-monophyletic in this analysis. Sound interpretation of the phylogenetic pattern discovered here would not have been possible without the acoustic, ecological and geographical investigations on species limits that preceded this work. To determine what biological and climatic factors influence the present day distributions of these cicadas, the distributions of two of the most closely related species in the P. annulata species complex were compared with the distributions of the tree species with which each is mainly associated. Because a large part of their life cycle is subterranean, soil texture, pH, electrical conductivity and force required for surface penetration were compared across sites where each of the cicadas occur in sympatry and allopatry. Finally, the influence of temperature and rainfall variables were investigated by testing 'predicted distribution' models (formed using positive distribution records) against negative records for both sets of variables, individually and in combination. The results show that the extent of the distribution of the cicada species is substantially less than that of the associated tree species. The geographical distributions of one of the species may be influenced more by rainfall, or a combination of temperature and rainfall, whereas the other species appears to be more influenced by temperature alone. Both species tolerate soils with a wide range of pH levels, electrical conductivity and forces required for surface penetration. They both showed a strong association with soils that had a silt loam texture, with only few records from sandy soils. However, none of the soils sampled where the cicadas occurred were heavy clays, which suggests that the physical properties of such soils may provide an unsuitable environment for the nymphal stages of the life cycle of these particular cicadas. The resolution of species limits within the P. annulata species complex allowed the redescription of Pauropsalta annulata Goding and Froggatt sensu stricto and the description of 11 new species belonging to the P. annulata species group, all from eastern Australia. Two of these species comprise two subspecies each, also all new. New distribution records and calling song data are documented for the allied species, P. ayrensis Ewart, which is redescribed to include the characters newly recognised in the present study as significant taxonomically with respect to Pauropsalta cicadas. The treatment includes comprehensive descriptions of the morphology and calling songs of the species and subspecies, and separate descriptive keys are provided for both sets of characters. The new taxa comprise P. artatus sp. nov., P. corymbiae sp. nov., P. decorus sp. nov., P. graniticus sp. nov., P. inversus inversus subsp. nov., P. i. laboris subsp. nov., P. notialis notialis subsp. nov., P. notialis incitatus subsp. nov., P. simplex sp. nov., P. subtropicus sp. nov, P. torrensis sp. nov. and P. tremulus sp. nov. Areas of hybridization between P. n. notialis subsp. nov. and P. n. incitatus subsp. nov. are also documented, together with their calling songs and morphology, which justifies their subspecific status. The P. inversus subspecies are allopatric, but consistently differ in the duration between phrases of the calling song. Finally, the results and conclusions are amalgamated into a critical reassessment of what defines species limits and the most appropriate approaches to investigating species limits in sexual organisms. Some historical discussions are revisited, such as the question of the reality of species and how species are perceived under the premises of neoDarwinism. The realism of species demands that species limits are most realistically defined in terms of their fertilisation mechanism, for this delimits the gene pool and thus the distribution of adaptations (the calling song of cicadas, for example).

Uma abordagem evolucionária de sistemas de relações de trabalho : o processo de co-evolução entre tecnologias e as instituições do trabalho

Costa, Rodrigo Morem da January 2014 (has links)
Esta tese estabelece uma abordagem evolucionária de sistemas de relações de trabalho (SRT- e), a qual consiste em propor uma ferramenta analítica que possibilite estudar as mudanças em sistemas de relações de trabalho ao longo do tempo como um processo evolutivo movido pelos avanços tecnológicos. Para esse intuito, o modelo de SRT desenvolvido por John Dunlop foi tomado como base, sendo modificado para compatibilizá-lo com as contribuições da Teoria Evolucionária. A alteração foi feita no sentido de tornar endógena ao modelo as fontes de geração de variedade no SRT desenvolvido por Dunlop, através de uma maior centralidade da firma, como aquela que desenvolve e introduz novas tecnologias na economia para obter vantagem competitiva em seu processo de concorrência no mercado, e da alteração na concepção do contexto do sistema de relações de trabalho. Desse modo, a mudança proposta permite que o nexo entre tecnologias físicas, rotinas organizacionais (tecnologia social), formas de regulação das relações de trabalho constantes nas regras (tecnologia social) e a teia de regras do SRT-e (instituições) seja estabelecido, consistindo no uso da “ponte” entre tecnologias e instituições, conforme sugerida por Richard Nelson. Com base na ferramenta de análise de SRT-e, o esforço teórico da tese foi, também, o de identificar como ocorre o alinhamento entre as inovações tecnológicas de um novo paradigma tecno- econômico e as instituições das relações de trabalho. Para tanto, foi explorada a ideia da “ponte” proposta por Richard Nelson, identificando do ponto de vista teórico, como ocorre a compatibilização entre as tecnologias e as instituições das relações de trabalho, que se constitui em um dos principais alinhamentos ao pleno estabelecimento de um novo paradigma tecno-econômico, ao permitir a efetividade de exploração do potencial de desenvolvimento econômico de um dado país. A proposta da tese está centrada em quatro áreas de pesquisa: relações de trabalho, teoria institucional, organização industrial e economia da tecnologia. Nessas áreas, o embasamento teórico é dado pelos campos de Industrial Relations e pela Economia Evolucionária: Neoschumpeteriana e Neoinstitucionalista. Em relação ao primeiro, é feita uma descrição desse campo de estudo e a apresentação do modelo de análise de relações de trabalho de John T. Dunlop, tal como proposto originalmente na sua obra Industrial Relations Systems, publicada em 1958. Indicam-se as suas propriedades e também as suas limitações para tratar com a mudança em relações de trabalho em sentido evolutivo. É sobre esse modelo que se aplica os construtos teóricos daquelas outras duas correntes que compõem a Teoria Evolucionária para torná-lo, então, um Sistema de Relações de Trabalho evolutivo (SRT-e). O esforço teórico consiste em modificar o modelo de SRT dunlopiano para assimilar e adaptar os princípios da teoria da evolução de Darwin. Os princípios darwinianos de uma abordagem evolucionária são a ocorrência endógena ao modelo de: variedade, seleção e herança. Da Teoria Neoschumpeteriana se toma emprestado a concepção de concorrência schumpeteriana, da tecnologia como um determinante básico da dinâmica da economia capitalista, da firma como a instituição que introduz as novidades tecnológicas no sistema, bem como o conceito de paradigma tecno-econômico, para explicar como os avanços tecnológicos modificam o SRT-e. A Teoria Neoinstitucionalista contribui com o conceito de instituição, na sua influência na vida econômica e para dar efetividade às inovações que são lançadas na economia. É feita, então, uma junção de conceitos dessas duas correntes de modo a mostrar como é feita a co-evolução entre as tecnologias e as instituições das relações de trabalho. / This thesis provides an evolutionary industrial relations systems approach (SRT-e), which consists in proposing an analytical tool that allows to study the changes in industrial relations systems over time as an evolutionary process driven by technological advances. For this purpose, the SRT model developed by John Dunlop was taken as a base and modified to bring them into line with the contribution of the Evolutionary Theory. The change occurs towards making endogenous to the model the sources that generates variety in the SRT developed by Dunlop, through greater centrality of the firm, as the one that develops and introduces new technologies into the economy to gain competitive advantage in the process of market competition, and by changing the conception of the context of the industrial relations system. Therefore, the proposed change allows that the link between physical technologies, organizational routines (social technology), forms of regulation of labor relations contained in the rules (social technology) and the web of rules of the SRT (institutions) is established, consisting in the use of the "bridge" between technologies and institutions suggested by Richard Nelson. Based on the analysis tool of SRT-e, the theoretical effort of the thesis was also aimed to identify how the alignment between technological innovations of a new techno- economic paradigm, and labor relations institutions occurs. It was explored the idea of the “bridge”, as suggested by Richard Nelson, identifying from a theoretical point of view, how the match between technologies and the institutions of industrial relations occurs, which is one of the main alignments necessary to the full establishment of a new techno-economic paradigm, allowing to the full deployment of the economic development potential of a given country to be achieved. The thesis proposal is centered on four areas of research: industrial relations, institutional theory, industrial organization theory, and technological economy. In these areas, the theoretical basis comes from the fields of Industrial Relations and Evolutionary Theory: Neoschumpeterian and Neo-institutionalist theories. Regarding to the first one, it is made a description of this field of study and a presentation of the model of analysis of IRS, as originally proposed by John T. Dunlop in his book Industrial Relations Systems, published in 1958. It will be indicated its proprieties and limitations in dealing with change in an evolutionary sense. It is on this model that will be applied the theoretical constructs from the other two stream of economic thought (Neoschumpeterian and Neo- institutionalist) to make it, then, an evolutionary industrial relations systems (SRT-e). The theoretical effort consists in modifying the dunlopian SRT model to assimilate and to adapt the principles of Darwin's theory of evolution. The darwinian principles of an evolutionary approach are the occurrence of variety, selection and inheritance as being endogenous to the model. From Neoschumpeterian Theory, it borrows the concept of Schumpeterian competition, and technology as a basic determinant of the dynamics of the capitalist economy, and the firm as the institution that introduces technological innovations in the system. Another relevant concept used from that theory is the techno-economic paradigm, which is used to explain how the technological advances modify the SRT-e. The Neo-Institutionalist Theory contributes with the concept of institution, its influence on the economic life, and the way that it gave effectiveness to the innovations that are introduced into the economy. Then, it will be make a junction of concepts of these two currents of economic thoughts so as to show that there is a co-evolution between technologies and the institutions of industrial relations.

Medievalism and the shocks of modernity: rewriting northern legend from Darwin to World War II

Geeraert, Dustin 13 September 2016 (has links)
Literary medievalism has always been critically controversial; it has often been dismissed as reactionary or escapist. This survey of major medievalist writers from America, England, Ireland and Iceland aims to demonstrate instead that medievalism is one of the characteristic literatures of modernity. Whereas realist fiction focuses on typical, plausible or common experiences of modernity, medievalist literature is anything but reactionary, for it focuses on the intellectual circumstances of modernity. Events such as the Enlightenment, the Industrial Revolution, many political revolutions, the world wars, and the scientific discoveries of Isaac Newton (1643-1727) and above all those of Charles Darwin (1809-1882), each sent out cultural shockwaves that changed western beliefs about the nature of humanity and the world. Thus, intellectual anachronisms pervade medievalist literature, as some of the greatest writers of modern times offer new perspectives on old legends. The first chapter of this study focuses on the impact of Darwin’s ideas on Victorian epic poems, particularly accounts of natural evolution and supernatural creation. The second chapter describes how late Victorian medievalists, abandoning primitivism and claims to historicity, pushed beyond the form of the retelling by simulating medieval literary genres. The third chapter crosses into the twentieth century and examines the relationship between the skepticism of a new generation of medievalist writers and their exploration of radical new possibilities in artificial mythology. The fourth chapter examines the gender dynamics of medievalist works, discussing how medievalist writers reinterpreted stock character types through metafiction. The final chapter’s focus is on war, propaganda, and human nature; it documents the iconoclastic trend in postwar medievalism, as writers examine the role of literature in encouraging nationalism and organized violence. Tying together the major threads of medievalism from the previous chapters, this final chapter chases the greatest shockwave of the twentieth century through inverted medieval landscapes where the author may be the greatest villain of all. Rejecting the critical Balkanization of medievalism, this study instead offers a unified view of nineteenth- and twentieth-century responses to northern legend, one which shows medievalism closely tracking the shocks of modernity. / October 2016

Web 2.0 : uma análise evolucionária do seu impacto nas empresas a nível global

Valdez Montalván, Daniel Borja January 2010 (has links)
O objetivo principal desta dissertação é analisar as tecnologias de aplicativos da Web 2.0, desde uma perspectivas evolucionária, e dos seus impactos nas empresas em nível global. Desta forma, para poder entender o seu nascimento, essência e importância econômica para as empresas, se tomou como base teórica o conceito evolucionário de revoluções tecnológicas e paradigmas tecno-econômicos, o qual serviu como modelo para interpretar a atual revolução das tecnologias de informação e comunicação (TIC) e seu conseqüente paradigma tecnoeconômico, e na qual se constatou que este grupo de tecnologias surgiu no período de tempo atual de dito paradigma conhecido como “intervalo de reacomodação” (turning point). Por outro lado, se ressaltou que uma das principais características no processo de difusão de cada paradigma tecno-econômico é o seu impacto na organização das empresas. Desta forma, a teoria evolucionária se apresentou como a abordagem adequada para entender tanto o caráter da empresa atual, entendida esta em termos do conjunto de suas rotinas (conhecimentos e habilidades), quanto as suas principais inovações organizacionais como respostas aos desafios apresentados pela própria difusão do paradigma tecno-econômico atual das TIC, na qual o acumulo permanente de novos conhecimentos e informações, isto é, de rotinas dinâmicas se tornam variáveis chaves para o próprio processo permanente de inovação, vital para as empresas. Diante da crescente utilização das tecnologias de aplicativos da Web 2.0 entre as empresas a nível mundial como meios potenciais para atingir esses objetivos, o presente trabalho analisou o seu potencial para gerar de forma mais fluida novos conhecimentos e informações, isto é rotinas dinâmicas, tanto dentro da organização das empresas como na interação com os seus consumidores, refletindo-se, assim, no aumento de inovações permanentes de novos produtos e serviços. / The main objective of this dissertation is to analyze the technologies of Web 2.0 applications, from an evolutionary perspective, and its impacts on businesses globally. Thus, in order to understand its birth, nature and economic importance for companies, it was taken as theoretical basis the evolutionary concept of technological revolutions and technoeconomic paradigms, which served as a model to interpret the current revolution in information and communication technologies (ICT) and its consequent techno-economic paradigm, in which it was found that this group of technologies originated in the current time of said paradigm known as turning point. On the other hand, it was emphasized that a key feature in the process of diffusion of each techno-economic paradigm is its impact on business organization. Thus, evolutionary theory appeared as the appropriate approach to understand both the character of the current company, which is understood in terms of its set of routines (knowledge and skills), as its main organizational innovations as answers to the challenges presented by the own diffusion of the current ICT techno-economic paradigm, in which the continuous accumulation of new knowledge and information, that is, dynamic routines, become key variables to the self process of continuous innovation, vital for companies. With the increasing use of Web 2.0 application technologies among the companies in the world as a potential means to achieve these goals, this study examined its potential to generate more fluidly new knowledge and information, that is dynamic routines, both within the business organizations and in their interaction with their consumers, which was reflected in the increase of permanent innovations of new products and services.

Aspectos evolutivos da depressão pós-parto e fatores associados / Evolutionary apects of postnatal depression and associated factors

Marcela Nosralla Bottino 26 April 2011 (has links)
Conselho Nacional de Desenvolvimento Científico e Tecnológico / A depressão pós-parto (DPP) é uma condição prevalente que afeta globalmente as mulheres puérperas. Uma hipótese evolutiva aborda a depressão, e consequentemente a DPP, como uma resposta proveniente da evolução do comportamento humano ao longo da História, através da seleção natural. A teoria do investimento parental sugere que os pais não investem automaticamente em toda prole; o investimento é direcionado para que o sucesso reprodutivo seja máximo. No caso de os riscos superarem os benefícios reprodutivos, sintomas de depressão se desenvolvem como sinal de alerta. O objetivo do estudo foi identificar fatores associados à DPP que fossem compatíveis com a teoria do investimento parental. Estudo transversal realizado com 811 mães de lactentes até cinco meses de idade, no município do Rio de Janeiro. A presença de DPP foi definida com base no escore da Escala de Edinburgh (EPDS). Fatores potencialmente associados à DPP foram analisados através de regressão logística com ajuste para fatores de confundimento. Os fatores significativamente associados à DPP foram: apoio social inadequado (OR 3,38; IC 95% 2,32-4,94), baixa escolaridade (OR 2,82; IC 95% 1,69-4,70), violência física entre parceiros íntimos na gestação (OR 2,33; IC 95% 1,56-3,47), idade materna inferior a 35 anos (OR 2,20; IC 95% 1,05-4,64), falta de companheiro (OR 1,90; IC 95% 1,16-3,12), internações durante a gestação (OR 1,87; IC 95% 1,12-3,14) e prematuridade do recém-nascido (OR 1,87; IC 95% 1,02-3,42). Em suma, identificamos alguns fatores associados à DPP que podem ser úteis no rastreamento e acompanhamento de mulheres de risco. Alguns dos fatores associados à DPP podem ser explicados através das hipotéses evolutivas contempladas neste estudo. Entretanto, os achados encontrados não são suficientes para esgotar o conhecimento referente a esta questão. Futuras pesquisas devem focar em diferentes abordagens desta condição e acompanhamento das consequências para as mulheres e suas famílias. / Postpartum depression (PPD) is a prevalent condition that affects women globally after they have given birth. An evolutionary hypothesis deals with depression, and consequently PPD, as a response from the evolution of human behavior throughout history, through natural selection. The parental investment theory suggests that parents do not automatically invest in all offspring, so that the investment is directed towards maximum reproductive success. If the risks outweigh fittness benefits, symptoms of depression develop as a warning sign. The objective of the study was to identify factors associated with PPD that were consistent with parental investment theory. Cross-sectional study with 811 mothers of infants up to five months of age in the municipality of Rio de Janeiro. The presence of PPD was defined based on scores on the Edinburgh Scale (EPDS). Factors potentially associated with PPD were analyzed by logistic regression with adjustment for confounding factors. Factors significantly associated with PPD were: inadequate social support (OR 3,38; 95% CI 2,32-4,94), low educational level (OR 2,82; 95% CI 1,69-4,70), physical violence between partners in gestation (OR 2,33; 95% CI 1,56- 3,47), maternal age under 35 years (OR 2,20; 95% CI 1,05-4,64), lack of partner (OR 1,90; 95% CI 1,16-3,12), hospitalization during pregnancy (OR 1,87; 95% CI 1,12- 3,14) and prematurity of the newborn (OR 1,87; 95% CI 1,02- 3,42). In summary, we identified factors associated with PPD which can be useful in tracking and monitoring women at risk. Some of the factors associated with PPD can be explained through the evolutionary hypotheses considered in this study. However, the findings are not sufficient to exhaust the knowledge regarding this question. Future research should focus on different aspects of this condition and monitoring of the consequences for women and their families.
