Abstract:
Debates engaging the problems of ahistoricism and Eurocentrism in International Relations (IR) theory have taken on new dimensions in recent years. Scholars from a variety of different theoretical traditions have aimed to reconstruct IR theory on stronger historical–sociological grounds, while re-orienting the study of IR away from the fetish of ‘Western’ thought and agency. Buzan and Lawson’s The Global Transformation offers a welcome contribution to these endeavours to furnish a non-Eurocentric historical sociology of international relations. This article seeks to push their project further by re-assessing the relationship between history, theory, and contingency. In particular, it interrogates whether Buzan and Lawson’s ‘configurational’ approach to the ‘global transformation’, emphasizing the contingent concatenation of historical events and social processes, results in a displacement of theory through an over-emphasis on the interaction of free-floating contingently related causes, causes that are external to any theoretical schema. This approach obscures the deeper, structural forces in the making of global modernity, most notably those that escape Buzan and Lawson’s singular focus on the ‘long 19th century’.

Abstract:
Purpose – The purpose of this paper is to present a newly developed fuzzy-set based model for estimating, allocating, depleting, and managing contingency fund over the life cycle of construction projects. Design/methodology/approach – Fuzzy set theory is utilized in the design and development of proposed contingency modelling framework to incorporate uncertainties associated with the development phases of construction projects. A set of developed indices, measures, and ratios are introduced to quantify and characterize these uncertainties. The developed framework is designed to incorporate expert opinion and provide user-system interaction. Findings – The results obtained from the application of the developed framework on actual project case not only illustrate its accuracy, but also demonstrate its capabilities for contingency management over life cycle of construction projects. Unlike other methods, the framework provides project managers with structured method for contingency depletion utilizing a set of depletion curves and selection factors. Originality/value – The novelty of the developed framework lies not only in its new developments for contingency estimating but also its modelling for contingency allocation and depletion. It is expected to be of direct value to industry professionals and academics interested in contingency management over the entire life cycle of construction projects. The proposed framework provides management functions and features beyond those generated through Monte Carlo simulation and even those developed using fuzzy set theory.

Abstract:
Applications of organizational theory to police organizations frequently employ the framework of structural contingency or institutional theories. The current study seeks to evaluate the impact of both technical and institutional environmental aspects of policing on the goals of municipal police agencies. The influence of a combination of environmental contingencies and chiefs’ ratings of institutional sectors is explored to assess which theory better explains chiefs’ emphasis on police agency goals. Relying on ordinary least squares regression models, the impact of two competing theoretical frameworks is assessed. Findings suggest that chiefs’ demographics (control variables) and legitimacy (institutional) factors have a greater impact than technical (structural contingency theory) elements on the goals that chiefs emphasize within their agencies. Potential theoretical advancement employing public sector agencies is also presented.

Abstract:
Purpose – This paper argues that international business (IB) theory needs to adapt to the changes that have occurred in the global economy when the world was divided into rich market economies, communist countries and poor economies. Changes in ideologies and technologies has opened up opportunities for emerging market multinational enterprises and the paper offers guidelines for a dynamic IB contingency theory to acknowledge these changes and learning. Design/methodology/approach – This is a conceptual paper which is designed to offer an alternative contingency perspective on IB theory. Findings – IB scholars should recognize the influence of several contingent variables such as the institutional environment, political systems, government-business-NGO relations, social norms-ethical behavior, country size and industry. The structural characteristics of an industry, their importance to the country and the regulatory regime are major variables in understanding how and whether firms can become emerging multinational enterprises (EMNEs). The paper finds that emerging market government and enterprises have strategies for building knowledge intensive industries through mergers and acquisitions and exploit these on a global scale. Research limitations/implications – IB scholars should recognize that multinational enterprises learn and they adapt to the global environment. Scholars should develop strategies or a way of thinking which is different to the status quo to take advantage of the new and changing circumstances where the rules of the game are different to those in the researcher's home country. Practical implications – The removal of trade barriers and government restrictions on trade and technological developments means that EMNEs and governments should not rely on protection and subsidies but should compete on being unique and adopt differentiated strategies in niche but global marketplaces.

Abstract:
I summarize my view of organization theory and then explain how it developed over my life. I stress that it arose gradually from a series of empirical tests, so that my views are based on good reasons, despite being in some ways unconventional. Early influences upon me include the non-conformist climate of my school days and the empirical ethos at the University of Aston. I have long been interested in the creation of social science. This has been informed by the philosophy of science, which emphasizes the centrality of theory and its empirical testing. My early work in the Aston programme laid the basis for commitment to functionalism and generalization. The vociferous rejection of this style of research by ideologically oriented critics led me to defend it, both theoretically and philosophically. My later work on strategy and structure led me to reject strategic choice and embrace situational determinism. I analysed these and other research topics as being within structural contingency theory. I also used this theory frequently in my business school teaching. In the USA, newer theories arose, which, collectively, fragmented organizational theory. I critiqued these theories, and this fragmentation. Moreover, I became convinced that contingency theory in its classic variant is more correct than newer variants, and offered detailed argumentation. My empirical research also found that crises of low performance triggered adaptive structural change. From that, I created organizational portfolio theory, which draws upon finance to explain performance fluctuations and the resultant organizational change and lack of change. More recently, I offered an integrated statement of structural contingency theory and ideas for its future development theoretically and methodologically.

Abstract:

Small business entrepreneurs (SBEs) within the United States in 2014 produced 47% of the national $17.5 trillion GDP and employed 48.5% of the national labor force. Detailed business planning was a theorized predictor of SBE performance and project, program, and portfolio management (P3M) as detailed managerial planning processes influenced by organizational theories. The specific problem was the failure of SBEs due to a lack of business management planning and the unknown generalizable U.S. SBE use of P3M as detailed managerial planning processes to enhance SBE performance. The purpose of this quantitative cross-sectional study was to statistically model U.S. SBE predictive P3M application to SBE Performance within a contingency theory framework using partial least squares structural equation modeling (PLS-SEM), hierarchical component modeling (HCM), and multi-group analysis (MGA-PLS) of subpopulations (growth orientation, number of employees, business age, business location, industry sector, legal form of organization, and P3M maturity). Random anonymous sampling among small business owners and chief managers was used to attain a representative sample by U.S. state using a web-based survey instrument. A sample of 179 was planned (R2 sensitivity of 0.1) and n =150 was attained (R2 sensitivity of 0.107). Sample size was representative of 93.1% of 28.9 million small business enterprises by U.S. state and the District of Columbia. Findings included an average performance efficiency of 59% among U.S. SMEs with room for improvement of 41%. P3M was identified as detailed planning and management processes with a 0.308 total effect on national SBE performance. A 1% improved adaptation of P3M managerial knowledge area processes predicted 18.17% SBE performance improvement. Limitations of the study included data collection barriers from internet service providers (ISPs) and email service providers (ESPs) in censoring and filtering emailed survey invitations contributing to a decreased response rate. Future research recommendations include expanding population ecology theory to identify predictive environmental factors that effect the 59% performance mean resulting in a population of SBEs failing or improving at various S-curve lifecycle stages.

Abstract:
Agency theory proposes that the role of the board of directors is to control management (Fama & Jensen 1983). A structurally independent board, one with a high percentage of non-executive directors and a chairperson who is not the CEO, has been used as a proxy for the control role. Therefore, agency theory predicts a positive relationship between independent board structure and firm performance. These predictions have not been confirmed by meta-analytic reviews (Dalton, Daily, Ellstrand, & Johnson 1998; Rhoades, Rechner, & Sundaramurthy 2000). This thesis applies structural contingency theory to provide an alternative explanation for the relationship between board structure and firm performance. Structural contingency theory (Donaldson 2001) proposes that the relationship between an organization???s structure and its performance is moderated by contingencies. In this study the contingency is the salience of the board???s control role. I argue that structural independence of the board has a beneficial effect on performance only if it is in fit with control salience. For example, a firm with an independently structured board that gives high prominence to the control role will perform well. On the other hand, another firm with a less independently structured board that does not see its main role as controlling management will also prosper. Survey data were analyzed to measure the control salience for 98 Australian listed companies. Archival data provided measures of board structure and firm performance. Consistent with the meta-analytic reviews, there was no association between independent board structure and firm performance. There was some evidence that high control salience resulted in high performance, but this effect was evident chiefly when performance was measured by total shareholder returns. This may indicate that the share market was responding to the symbolism of high control salience. In contrast to the symbolic main effect of control salience, the fit between the control salience and the independent structure of the board caused increased return on equity. This reflects the board???s objective effect on profit when its structure is in fit with control salience.

Abstract:
This study developed and tested a contingency model of group communication in Korean workgroups that posited that the communication effectiveness and group performance of workgroups is determined by the “fit” of communication practices with organization structure and group relational climate. A contingency model incorporates three variables: contingency variables, response variables, and performance variables. Based on a review of the literature on Korean organizations and groups, the model incorporated two contingency variables: organizational structure and group relational climate. Organizational structure was indexed by the level of centralization and formalizations in the organization. Group relational climate was indexed by the level of closeness and group conformity among members. The response variables, communication practices of Korean workgroups, was measured in terms of the frequency of formal and informal meetings held by the workgroups. Two types of performance were measured: communication effectiveness and performance level. The contingency model hypothesized that the level of communication effectiveness and group performance of a workgroup that engages in communication practices which fit the requirements of organizational structure and group relational climate will be higher than that of a group whose communication practices do not fit the requirements of organizational structure and group relational climate. It also hypothesized the communication effectiveness group performance would be lower in groups which faced conflicting contingencies than in groups that faced consistent contingencies. A survey of 409 members of 84 workgroups in 37 Korean organizations was conducted. Results of this study supported the predictions of the contingency model. In particular, centralization, formalization, and closeness were significant contingency variables. The hypothesis regarding conflicting contingency was not supported. Implications of the study regarding the contingency theory, group communication and group effectiveness, and the nature of Korean groups and organizations are discussed.

Abstract:
Abstract Small businesses are numerous in any country. However, we have very limited knowledge regarding their management accounting (MA) and management control systems (MCS). Traditionally, it has been stated that small firms do not need and use MCS due to their simple structures and poor resources. On the other hand, a few studies on high technology firms have shown that these firms have developed their MCS and are also utilizing sophisticated management accounting practices and information. The aim of this study is to analyse small firms' use of MCS practices as well as to examine the role of MCS practices and information of small firms in a contingency theoretical framework. Furthermore, the study is not only focusing on small, rapidly growing firms but also on traditional, more stable small firms, all employing from 10 to 49 persons. Based on the survey responses of 183 managing directors of small Finnish firms, the study describes the diffusion and penetration of MCS practices and information among small firms. Two theoretical models are constructed linking the use of MCS with strategy, perceived environmental uncertainty (PEU), use of diversified management team and financial performance of small firms. Tests are made by using structural equation modeling (SEM). The results suggest that small firms do use a wide range of MCS practices and information. The main results also indicate that the use of a more diversified management team seems to increase the use of MCS practices and information. The use of more advanced practices is related to small firms which have been more profitable or which have had lower growth rates in sales. In addition, the use of MCS seems to be associated with small firms' strategies, both realized and intended. The pursued strategy seems to drive small firms' profitability and growth in net sales. However, such an association was not found between the intended strategy and financial performance after two years. The use of MCS seems to have only a few positive effects on small firm's financial performance. Nevertheless, more use of advanced dimensions of MCS seems to predict significant improvements for longer-term growth in net sales.

Abstract:
This quantitative research study investigated the impact of organisational context on the process and success of strategic IS planning (SISP) in post-implementation information systems in Libyan organisations. A set of direct and indirect relationships were investigated in the research model. The organisational context presented as a contingent situational variable mediated by SISP process and predicted by SISP success (the criterion variable). The causality of the relationship set was developed from the contingency theory of information systems and supported by fit models in strategic management research. The study deployed multivariate analysis represented in the structural equation modelling (SEM) to develop robust construct measurements and analyse data collected from executives responsible for information systems planning in both public and private Libyan organisations. Multi-dimensional multi-items constructs were used in the path analysis model after they were extensively validated. The path analysis model represented as mediation model, where hypothesise suggest that SISP context has an impact SISP success, through the influence of the SISP process. In the model, four dimensions of the SISP context construct were found to have a significant impact on SISP success directly and indirectly through the SISP process. Two of these dimensions are components of the leadership orientation construct, namely “Creative and Controlling” leadership. The other two dimensions are “Organisation centralisation structure and the Riskiness of organisation strategies”. The environmental uncertainty and planning resource constructs were found to have no impact on SISP success in Libyan organisations. Furthermore, this study validated six out of seven dimensions of SISP process construct measurement; only five exhibited acceptable fit level in the path analysis model and all were affected by the SISP context. However, just three out of five SISP process constructs had an impact on SISP success namely “Comprehensiveness, Focus and Intuition planning process”. Different SISP processes were associated with different levels of SISP success, “Intuition” was the most effective SISP process approach. The second most effective SISP process approach was the “Focus on innovation”, followed by “Limited comprehensiveness”. The SISP success measured by the fulfilment of key objectives that has three measurements constructs namely “Analysis, Alignment, and Cooperation”. The research suggest that under the effect of organisation context the most successful SISP produced by (CIO, CEO, or top executives) who rely less on personal judgment, focus more on innovation rather than control and limit their comprehensiveness of information systems planning process.

Abstract:
Bakgrund & problem: CSR, Corporate Social Responsibility, är sedan länge ett väl utforskat område, både i Sverige och internationellt, där många tidigare studier behandlar dess koppling till finansiell prestation, framförallt inom stora företag. Ett område som är relativt outforskat är CSR inom idrottsvärlden och vidare inom fotboll, framförallt ur en svensk kontext. I vilken utsträckning engagerar sig svenska fotbollsföreningar i CSR-relaterade aktiviteter och vilken effekt har det för deras prestation? Syfte: Syftet med studien är att testa och förklara CSR-engagemangs påverkan på svenska fotbollsföreningars HR- och sociala prestation samt om organisationsstruktur i termer av formaliserings-, centraliserings- och komplexitetsgrad påverkar detta samband. Vidare är det praktiska syftet att bidra med vägledning för hur svenska fotbollsföreningar kan arbeta med CSR-engagemang för att uppnå en högre prestation. Avsikten är att belysa och förklara kopplingarna mellan CSR-engagemang, prestation och organisationsstruktur och på så sätt fylla det gap som existerar inom forskningsområdet. Metod: Studien utgår från en kvantitativ forskningsstrategi med en deduktiv forskningsansats och tvärsnittsdesign. Insamlande av data har skett genom utskick av en enkät och studiens urval består av 223 fotbollsföreningar från Allsvenskan till Division 2. Slutsatser: Studiens resultat visar tydligt att CSR-engagemang påverkar såväl HR- som social prestation positivt inom svenska fotbollsföreningar. Vidare tyder resultatet på att organisationsstruktur i termer av formaliserings- och centraliseringsgrad samt komplexitet hierarki inte påverkar detta samband. Däremot finns det, trots viss osäkerhet i resultaten, en påverkan av komplexitet socialt kapital i relationen mellan CSR-engagemang och HR- prestation.
Background & problem: CSR, Corporate Social Responsibility, is since long ago a well explored area, both in Sweden and internationally, where many previous studies deal with the connection to financial performance, especially in large companies. An area which is relatively unexplored is CSR within the sports industry and further on within football, especially from a swedish context. To which extent do swedish football clubs engage in CSR-related activities and what effect does it have on their performance? Purpose: The purpose of the thesis is to test and explain the impact of CSR-engagement onswedish football clubs’ HR- and social performance and if organizational structure in terms of formalization, centralization and complexity affects this relationship. Furthermore, the practical purpose is to contribute with guidance on how swedish football clubs can work with CSR- engagement in order to accomplish a higher performance. The intent is to highlight and explain the connections between CSR-engagement, performance and organizational structure and thus fill the gap that exists within the research area. Method: The thesis is based on a quantitative research strategy with a deductive research approach and cross-sectional design. Data collection has been done by sending out a survey and the selection of the thesis consists of 223 football clubs from Allsvenskan to Division 2. Conclusions: The result of the study clearly shows that CSR-engagement positively affects both HR- and social performance in Swedish football clubs. Furthermore, the result indicates that organizational structure in terms of formalization, centralization and complexity hierarchy does not affect this relationship. However, despite some uncertainty in the results, there is an impact of complexity social capital in the relationship between CSR-engagement and HR- performance.

Abstract:
The purpose of this study is to examine how traditional school districts create online schools and how they navigate contingencies to establish online organizational structures. This study uses the theoretical framework of contingency theory to understand how school districts structurally adapt to internal and external factors, or contingencies to establish new online schools. This multiple case study collected data from three online schools in California that have opened in the past two to seven years. While some research exists concerning the challenges of creating online schools, little has been done as to the challenges and factors that traditional school districts encounter in creating and organizing online schools. The findings from this study revealed that online schools must adapt to contingencies through adaptation features. These identified features were divided into categories that included addressing the context; systems planning, management, and leadership; and in-process adaptability. These findings have important implications for traditional school districts with online schools or exploring the option of creating an online school, as well as for policy makers who help define the contingencies online schools face.

Full text
Abstract:
Understanding organizational behavior (OB) has profoundly influenced organizational performance and how people behave in organizations. Researchers have suggested various micro and macro organizational behaviors to be the impetus for high-performing organizations. Through a policy capturing approach this study builds on these findings by specifically examining the perceptions of micro and macro organizational behaviors in an organizational setting. The participants (n =181) completed a Micro and Macro Organizational Behavior Perceptions Questionnaire. Results showed perception differences exist between subordinates and supervisors. Additionally, participants perceived job satisfaction to be the most important micro organizational behavior, whereas organizational design was perceived to be the most important macro organizational behavior. However when comparing hierarchal positions in the organization, supervisors weighted leadership as the most important and subordinates weighted job satisfaction as the most important organizational behavior. While these findings only scratch the surface as to how organizational behavior is perceived, the implications challenge leaders to close the OB perception gap. Correspondingly, organizational behavior thinking may result in improving individual and organizational performance.

Résumé

Le cadre théorique de la contingence structurelle associe généralement « contexte, structure et performance » (Burns et Stalker, 1961; Woodward, 1965; Lawrence et Lorsch, 1967 ;Mintzberg, 1979).Le besoin de tester cette théorie dans l’environnement d’un pays sous développé (PSD) nous a conduit, dans cette recherche, à l’utilisation d’un cadre réduit basé uniquement sur des liens entre la technologie (remplacée par TI) et la structure (Galbraith, 1972 ;Lacrampe, 1974 ;Leifer, 1988).

Notre cadre théorique s’appuie sur les approches managériales, économiques et organisationnelles des TI et de l’EDI (Leavitt, 1968 ;Scott Morton, 1991). Il utilise la théorie contingente de la gestion comptable (Otley, 1980; Chapman, 1997) et des systèmes d’information comptable AIS (Sutton, 1995; Maudlin et Ruchala, 1999; Baldwin et alii, 2000; Dunk, 2001) comme domaine d’opérationnalisation (système d’information fonctionnel).

Abstract:
Les modèles d'occupation de niche au sein des communautés locales, la variabilité spatiale de la biodiversité le long des gradients environnementaux du stress et des perturbations, et les processus de succession végétale sont plusieurs sujets fondamentaux en écologie. Récemment, l'approche basée sur les traits est apparue comme un moyen prometteur de comprendre les processus structurant les communautés végétales et cette approche a même été proposée comme méthode pour reconstruire l'écologie communautaire en fonction des traits fonctionnels. Par conséquent, lier ces thèmes fondamentaux en utilisant une lentille fonctionnelle devrait nous donner un aperçu de certaines questions fondamentales en écologie et sera l'objectif principal de ma thèse. En général, mon projet de doctorat vise à étudier les structures de l'occupation de l'espace fonctionnel dans les gradients spatio-temporels. Plus précisément, l'objectif du chapitre 2 est (i) d'étudier les modèles d'occupation de la niche fonctionnelle en calculant trois métriques clés de niche (le volume total de niche fonctionnelle , le chevauchement des niches fonctionnelles et le volume de niche fonctionnel moyen) des communautés pauvres en espèces aux communautés riches en espèces et (ii) de déterminer le principal facteur de la structure observée de l'occupation de la niche fonctionnelle dans les communautés végétales du monde entier. Dans le chapitre 3, je vise à prédire et à expliquer la variation de la richesse en espèces selon les gradients de stress et de perturbation, en reliant le modèle d'équilibre dynamique et l'occupation de la niche fonctionnelle en fonction du cadre développé au chapitre 2. L'objectif du chapitre 4 est de tester expérimentalement l’application d'une méthode d'ordination CSR évaluée globalement en fonction de trois traits de feuilles (surface foliaire, teneur en matière sèche des feuilles et surface foliaire spécifique) dans les études locales. Enfin, l'objectif du chapitre 5 est de tester expérimentalement les hypothèses qui concilient les points de vue déterministes et historiquement contingents de la succession végétale, en étudiant la variation des divergences taxonomiques et fonctionnelles entre les communautés selon des gradients de stress et de perturbation. L'étude globale (chapitre 2) est basée sur une collection de 21 jeux de données, couvrant les biomes tropicaux et tempérés, et se compose de 313 communautés végétales représentant différentes formes de croissance. Les études locales (chapitre 3, 4 et 5) sont basées sur le même système expérimental constitué de 24 mésocosmes présentant différents niveaux de stress et de perturbation. L'expérience a commencé en 2009 avec le même mélange de graines de 30 espèces herbacées semées sur les 24 mésocosmes et s'est terminée en 2016. Nous avons permis la colonisation naturelle de graines de la banque commune de graines de sol et de l'environnement pendant la succession de sept ans. Dix traits ont été mesurés sur cinq individus (échantillonnés directement à partir des mésocosmes) par espèce par mésocosme en 2014 (chapitre 3 et 4). Un autre ensemble de traits (16 traits, y compris certains traits qui ne pouvaient pas être mesurés directement dans les mésocosmes), ont été mesurés au niveau de l'espèce (valeurs moyennes des traits) pour les 34 espèces les plus abondantes (certaines espèces disparues dans les mésocosmes) au cours des sept Ans, en les regroupant séparément pour une saison de croissance. Au chapitre 2, nous avons constaté que les communautés étaient plus diverses en termes fonctionnels (une augmentation du volume fonctionnel total) dans les communautés riches en espèces et que les espèces se chevauchaient davantage au sein de la communauté (augmentation du chevauchement fonctionnel), mais ne divisaient pas plus finement l'espace fonctionnel (aucune réduction du volume fonctionnel moyen). En outre, le filtrage de l'habitat est un processus répandu qui conduit à la caractérisation de l'occupation de niche fonctionnelle dans les communautés végétales. Dans le chapitre 3, nous avons trouvé un modèle similaire d'occupation de niche fonctionnelle sur un système expérimental avec une taille spatiale communautaire constante et un effort d'échantillonnage des traits, qui, avec le chapitre 2, nous a fourni une image plus complète et plus solide de l'occupation de niche fonctionnelle dans les communautés végétales. De plus, nous avons réussi à relier le modèle de l'occupation de la niche fonctionnelle et le modèle d'équilibre dynamique et avons constaté que le filtrage concurrentiel était le processus dominant qui détermine le mode d'occupation de la niche fonctionnelle et la richesse des espèces le long du stress et de la perturbation des gradients. Au chapitre 4, nous fournissons un soutien empirique à une méthode d'ordination CSR calibrée globalement en montrant une relation entre l'abondance relative d'espèces en croissance dans les mésocosmes ayant différents niveaux de fertilité du sol et mortalité indépendante de la densité et leur classification CSR. Au chapitre 5, nous avons montré que la succession d'installations au cours de sept ans dans ces mésocosmes était plus déterministe d'un point de vue fonctionnel, mais plus historiquement contingent d'un point de vue taxonomique et que l'importance relative de la contingence historique a diminué à mesure que l'environnement devenait plus stressé ou perturbé. En conclusion, les structures de l'occupation de l'espace fonctionnel dans (le volume fonctionnel total, le chevauchement fonctionnel et le volume fonctionnel moyen, les Chapitre 2 et 3) ou entre les communautés locales (dissimilarité fonctionnelle, chapitre 5) sont déterministes plutôt que neutres (ou contingence historique ). Les espèces tolératrices de stress sont plus avantagées dans les mésocosmes moins fertiles tandis que les espèces rudérales sont plus avantagées dans les mésocosmes avec plus de mortalité indépendante de la densité.
Abstract : The patterns of niche occupancy within local communities, the spatial variability of biodiversity along environmental gradients of stress and disturbance, and the processes of plant succession are several fundamental topics in ecology. Recently, the trait-based approach has emerged as a promising way to understand the processes structuring plant communities and has even been proposed as a method to rebuild community ecology based on functional traits. Therefore, linking these fundamental themes through a functional lens should give us more insight into some basic questions in ecology and will be the main objective of my thesis. Generally, my PhD project is to investigate the structures of functional space occupancy along both spatial and temporal gradients. Specifically, the objective of Chapter 2 is to investigate the patterns of functional niche occupancy by calculating three key niche metrics (the total functional niche volume, the functional niche overlap and the average functional niche volume) from speciespoor communities to species-rich communities and to determine the main driver of the observed pattern of functional niche occupancy across plant communities worldwide. In Chapter 3, I aim to predict and explain the variation of species richness along gradients of stress and disturbance, by linking the dynamic equilibrium model and functional niche occupancy based on the framework developed in Chapter 2. The objective of Chapter 4 is to experimentally test the application of a globally calibrated CSR ordination method based on three leaf traits (leaf area, leaf dry matter content and specific leaf area) in local studies. Finally, the aim of Chapter 5 is to experimentally test the hypotheses reconciling the deterministic and historically contingent views of plant succession, by investigating the variation of taxonomic and functional dissimilarities between communities along gradients of stress and disturbance. The global study (Chapter 2) is based on a collection 21 trait datasets, spanning tropical to temperate biomes, and consisting of 313 plant communities representing different growth forms. The local studies (Chapter 3, 4 and 5) are based on the same experimental system consisting of 24 mesocosms experiencing different levels of stress and disturbance. The experiment started in 2009 with the same seed mixture of 30 herbaceous species broadcast over the 24 mesocosms and ended in 2016. We allowed natural colonization of seeds from the common soil seed bank and from the surroundings during the seven-year succession. Ten traits were measured on five individuals (sampled directly from the mesocosms) per species per mesocosms in 2014 (Chapter 3 and 4). Another set of traits (16 traits including some traits that were not able to measured directly in the mesocosms) were measured at the species level (species mean traits values) for the 34 most abundant species (some species disappeared in the mesocosms) over the seven years, by regrowing them separately for one growing season. In Chapter 2, we found communities were more functionally diverse (an increase in total functional volume) in species-rich communities, and species overlapped more within the community (an increase in functional overlap) but did not more finely divide the functional space (no decline in average functional volume). Moreover, habitat filtering is a widespread process driving the pattern of functional niche occupancy across plant communities. In Chapter 3, we found a similar pattern of functional niche occupancy on an experimental system with a constant community spatial size and trait-sampling effort, which together with Chapter 2 provided us a more comprehensive and robust picture of functional niche occupancy across plant communities. In addition, we succeeded in linking the pattern of functional niche occupancy and the dynamic equilibrium model and found that habitat filtering was the dominant process determining the pattern of functional niche occupancy and species richness along the gradients stress and disturbance. In Chapter 4, we provide empirical support for a globally calibrated CSR ordination method by showing a relationship between the relative abundance of species growing in mesocosms having different levels of soil fertility and density-independent mortality and their CSR classification. In Chapter 5, we showed that plant succession over seven years in these mesocosms was more deterministic from a functional perspective but more historically contingent from a taxonomic perspective, and that the relative importance of historical contingency decreased as the environment became more stressed or disturbed. In conclusion, the structures of functional space occupancy within (the total functional volume, the functional overlap and the average functional volume; Chapter 2 and 3) or between local communities (functional dissimilarity, Chapter 5) are deterministic rather than neutral (or historical contingency). Stress-tolerators were more favored in high stress communities, while ruderals are more favored in high disturbed mesocosms (Chapter 4).

Abstract:
Aesthetics of contingency provides an important reconsideration of seventeenth-century literature in light of new understandings of the English past. Emphasising the contingency of the political in revolutionary England and its extended aftermath, Matthew Augustine challenges prevailing literary histories plotted according to structural conflicts and teleological narrative. In their place, he offers an innovative account of imaginative and polemical writing, in an effort to view later seventeenth-century literature on its own terms: without certainty about the future, or indeed the recent past. In hewing to this premise, the familiar outline of the period – with red lines drawn at 1642, 1660, or 1688 – becomes suggestively blurred. For all of Milton’s prophetic gestures, for all of Dryden’s presumption to speak for, to epitomise his Age, writing from the later decades of the seventeenth century remained supremely responsive to uncertainty, to the tremors of civil conflict and to the enduring crises and contradictions of Stuart governance. A study of major writings from the Personal Rule to the Glorious Revolution and beyond, this book also re-examines the material conditions of literature in this age. By carefully deciphering the multi-layered forces at work in acts of writing and reception, and with due consideration for the forms in which texts were cast, this book explores the complex nature of making meaning in and making meaning out of later Stuart England.

Abstract:
The dominant view amongst contemporary analytic metaphysicians working on notions of metaphysical dependence and the overarching structure of reality is one according to which that reality is hierarchically structured (the hierarchy thesis), well-founded (the fundamentality thesis), populated by merely contingent fundamentalia (the contingency thesis), and consistent (the consistency thesis). The introduction to this volume addresses the reasons commonly offered in defence of these theses and evaluates their merits. If it is correct that these are the core commitments of the metaphysical foundationalist, then it is proposed that the view is not nearly on such firm footing as one might suppose. The chapter also argues that the alternatives to this view—metaphysical infinitism and metaphysical coherentism—ought to be taken more seriously.

Abstract:
This chapter explores Christian extreme metal as a window on the way religion is expressed in contemporary Western culture, drawing on continental theorists of the post-secular. Christian extreme metal lyrics, sonic and structural musical features, and visual features are remarkably continuous with “secular” extreme metal, which positions itself in explicit opposition to Christianity and the “mainstream” world. But Christian extreme metal fans see Christian metal as qualitatively different from “secular” extreme metal. This apparent contradiction shows powerfully how religious symbols circulate in Western late modernity: religious symbols (e.g., biblical texts, stories, languages, and characters—and their symbolic inversions and opposites, drawn on in “secular” extreme metal) have been divested of their truth value and instead circulate as symbols, as meanings with experiential consequences. This allows for a surprising flow of symbols and meanings between secular and Christian extreme metal, and at the same time for qualitatively unique experiences.

Abstract:
Political theory tends to react to upsurges in populist politics in the real world, explaining them in turn as largely reactions to contemporary political crises, and in terms of regional styles, American or European most commonly. But for students of political theory, populism in theory and in practice has only been contingently, rather than structurally, related to the history of democratic politics and the growth of popular sovereignty. This chapter argues by contrast that populism is part of the mainstream structural history of popular sovereignty, and moreover, that such a history connects European and American democratic politics from the period of the 1848 revolutions through to the present. Taking populist politics as one component part of this transnational history, it also claims that the derivative reliance upon different national styles of populism misses something deeper about the relationship between populism and modern political theory.

Full text
Abstract:
This volume brings together fourteen essays from leading and emerging scholars that address issues relating to the view that has come to be known as metaphysical foundationalism, and explore possibilities regarding its alternatives. According to the foundationalist, reality is hierarchically arranged with chains of entities ordered by metaphysical dependence relations that terminate in a fundamental ground populated by consistent and contingent entities. Each essay in this volume addresses some aspect or other of at least one of these core commitments. Must there be anything fundamental? Is reality hierarchically structured? Why should we be foundationalists? Is metaphysical infinitism possible? Is metaphysical coherentism possible? What does reality look like if we allow inconsistent fundamentalia? These are the sorts of pertinent questions seldom asked in the current literature, and exactly the kinds of questions addressed in this volume. The volume, then, aims to open up a much broader perspective on metaphysical dependence than currently exists, and point to ways of exploring new avenues of thought on the subject.

Full text
Abstract:
This chapter provides a theoretical framework for considering how imaginaries and narratives interact with calculative devices to structure expectations and beliefs in the economy. It analyses the nature of uncertainty in innovative market economies and examines how economic actors use imaginaries, narratives, models, and calculative practices to coordinate and legitimize action, determine value, and establish sufficient conviction to act despite the uncertainty they face. Placing the themes of the volume in the context of broader trends in economics and sociology, the chapter argues that, in conditions of widespread radical uncertainty, there is no uniquely rational set of expectations, and there are no optimal strategies or objective probability functions; instead, expectations are often structured by contingent narratives or socially constructed imaginaries. Moreover, since expectations are not anchored in a pre-existing future reality but have an important role in creating the future, they become legitimate objects of political debate and crucial instruments of power in markets and societies.

Full text
Abstract:
Although the schismatic and iconoclastic sensibilities visible in French reformed satires doomed the movement in France, a number of attitudes explored through the fantastic-voyage device spread into French culture generally. Montaigne illustrates how the French, exposed to such ideas earlier in their lives, assimilated their conclusions even as they rejected the Reformation. Montaigne’s celebrated essay “Of Cannibals” turns both the surface imagery and the deeper structure of Reformation satire toward a new form of “inner distance” where one entertains considering oneself a stranger. Responding to reformers’ emphasis on the contingency of custom and their new procedures of observation, the essay defamiliarizes the Mass through implicit comparison with the ceremony of cannibalism. Finally, Montaigne avails himself of “stranger sociability” in elaborating a new form of anonymous intimacy with his reader. France may have remained confessionally Catholic, but it became culturally reformed.

Abstract:
Utilizing the lens of Heider's (1958) attribution theory and Grable and Joo's (2004) conceptual framework, this chapter studies the effect of situational and dispositional attributions on changes in financial risk tolerance. Situational factors are assessed through changes in household situation and changes in macroeconomic factors. For dispositional factors, changes upon sensation seeking attitudes are explored. The data employed in this research come from the 1993, 1994, and 2006 National Longitudinal Survey of Youth (N = 5,449). Results from structural equation modeling indicate that changes in internal attributions have a significant and positive effect (coefficient = 0.12, p <0.01) on the change in risk tolerance, as is true for changes in external attributions where a significant effect is seen (coefficient = 0.30, p <0.01). Thus, the findings from this study support the conceptual framework premised on Heider's attribution theory and Grable and Joo's (2004) conceptual model.

The first one is a critical reflection on some structural limits of the Indicator Frameworks used to evaluate the quality of Early Childhood Education and Care services (ECEC), since they rely mainly on measures of the structural and processual characteristics of the educational settings. As a consequence, the processual dimensions are reduced to their individual components, overlooking the complex and contingent interactions that create opportunities for learning. The second aim is to propose a framework, based on Basil Bernstein’s theory to analyse the different child-centred approaches to ECEC.

Abstract:
With the implementation of the new steering model (NSM), universities should align themselves more closely with management principles. Especially, the heads of faculties must cope with higher demands of management tasks. As a result, more management positions are established and organizational structures are changed. To shed light on how structures change, we investigate the faculties of one comprehensive and one technical university within Germany – which are similar in many factors – using the contingency approach. Information about context factors and the number and type of established positions is gained from a systematic analysis of their homepages. Dimensions of the organizational structure are used to interpret the results. Our comparison shows that the technical university, which has established itself as an entrepreneurial university, orients its organizational structure more towards the NSM than the comprehensive university, which is reflected by more support positions in faculty management. Thus, the profile and type of the university seem to be crucial context factors, while our study revealed that the number of students of the faculties and the number or type of degree programs are less crucial context factors.

Abstract:
Risk management is the subject of increasing attention in recent years. In the US, when Federal funds are committed to projects, risk management is a required programmatic activity. Even when it is not mandated by law or regulation, risk management is prudent for expensive, long-duration projects. Frequently, risk management is based on a risk register, and often captures as a list of typical problems with design and construction that a contractor has experienced. Risk registers vary in quality and usefulness. Some contractor submissions appear to be more “pro-forma” documents, while more useful risk registers will include anticipated risks tailored to the complexity of the scope of work and the contractor’s anticipated solution. This qualitative approach can develop a reasonable view of key risks and work to mitigate them. Recent experience at Arup has shown that this approach, while valuable as an initial approach, is limited by its quantitative nature. This paper will explore some of the key lessons learned and emerging practices that have been successfully used in recent work in detail. Key topics include: • While the essential elements of risk management apply across a wide range of markets, the planning and construction of risk management for due diligence, privately funded and partnership funded (both government and PPP) projects require different emphases and tailored approaches. • Appropriate risk structuring is required to identify key project risks that may be unrelated or marginally related to design and construction. Developing clear and effective ancillary risk statements (e.g., for marketing, finance, permitting and regulatory requirements) is important to successful risk management. • Where partnering is used for funding, there is a greater need for clarity and good communication. Planning documents require special consideration to minimize difficulties. Planning documents also need to be efficient and effective. • Large, sometimes geographically diverse, teams benefit from alternative approaches to risk workshops. • Large, expensive and long duration projects benefit by shifting risk analysis toward a more quantitative approach. Modeling techniques such as Monte Carlo simulation require special software (@Risk or Primavera) and sound input. Analyses that move risk statements from the essentially qualitative (such as severity of 4 and likelihood of 3) to agreed quantitative inputs are important. • Cost and schedule contingency are key concerns for funding agencies, whether in-house or external. The underlying structure for effectively constructing contingency depends on the contracting structure, sequencing of work, unit price allowances and other factors, in addition to the analysis of the contingency requirements of technical and other specific risks. • Special analyses for items of particular concern, for instance, the adequacy of escalation allowances or geotechnical risks, can also be helpful, particularly in the context of emerging technologies such as HSR. Risk management is coming of age, and is more than a risk register. Projects benefit from a more qualitative approach. Not every technique applies to every project, of course, but most projects, small and large, can benefit from a more structured, quantitative approach to risk management.

Abstract:
A comprehensive risk management framework (RMF) was developed and introduced to help management deal with the project risks in today’s changing world using a well-defined process. Several projects were analyzed to determine their causes of failure and identify risk elements. The RMF consisted of six phases; project identification, risk identification, risk assessment, response development, contingency planning, and implementation and control. Each process must be tailored to the particular circumstances of the project and of the organization undertaking it. The RMF treated risks in a structured process starting by identifying the project and the potential risks, assessing these risks and responding to each risk. Using such an approach management can identify potential risks that may affect the project and respond proactively. The developed framework is comprehensive and applicable for any project type.

Abstract:
High-speed rail infrastructures support the fastest and safest passenger ground transportation mode in existence. Since these infrastructures represent a major achievement of human ingenuity, they are expected to be exceptional. However, the cost of high-speed rail infrastructure does not have to mirror such exceptional status under all circumstances. Well documented yet underutilized civil engineering concepts and features exist that carry considerable cost reduction potentials. They are based on experience with strategic project structuring, appreciation of dynamic track/train interaction trends that control high speed movement, maintenance experience, and component testing. Their utilization is often contingent upon engineering necessary to perform adjustments due to specific conditions, and on availability of verification testing to overcome the established status quo. This article is based on practical consulting and operational experience. The presented issues include concepts of cost-effective positioning of civil engineering subsystems in a high-speed rail project, detection and avoidance of cost-rising zones by alignment selection, trackwork geometries and structural features justifying major reductions of horizontal radii, cost-effective selection and use of slabtrack, and cost minimization steps recommended in high-speed rail tunnel design. Supportive theoretical backgrounds exist; however, their presentation would require several papers.

Most existing works in Probabilistic Simple Temporal Networks (PSTNs) base their frameworks on well-defined probability distributions. This paper addresses on PSTN Dynamic Controllability (DC) robustness measure, i.e. the execution success probability of a network under dynamic control. We consider PSTNs where the probability distributions of the contingent edges are ordinary distributed (e.g. non-parametric, non-symmetric). We introduce the concepts of dispatching protocol (DP) as well as DP-robustness, the probability of success under a predefined dynamic policy. We propose a fixed-parameter pseudo-polynomial time algorithm to compute the exact DP-robustness of any PSTN under NextFirst protocol, and apply to various PSTN datasets, including the real case of planetary exploration in the context of the Mars 2020 rover, and propose an original structural analysis.

Abstract:
The Materials Reliability Program (MRP) Reactor Internals Focus Group (RI-FG) developed Pressurized Water Reactor (PWR) Internals Inspection and Evaluation (I&E) Guidelines under the sponsorship of the Electric Power Research Institute (EPRI). The I&E guidelines summarized in MRP-227 [1], provide a generic basis for U.S. utilities to develop their Aging Management Program (AMP) for managing the long-term aging degradation of PWR reactor internals including the existing and extended license periods. A number of internals structural bolts in the Babcock & Wilcox (B&W) design PWRs are fabricated from high-strength alloys such as Alloy A-286 or Alloy X-750. The materials in general, and bolts in particular, are known to be susceptible to stress corrosion cracking (SCC) based on past operating experience. The Upper and Lower Core Barrel (UCB and LCB) bolts have a core support function and have been generically categorized as Primary components for inspection in the I&E Guidelines. The remaining Alloy A-286 and Alloy X-750 structural bolts are in the Expansion category. Per 10CFR54, all U.S. PWRs are required to establish a unit-specific AMP for the extended license period in accordance with the ten elements of an effective AMP outlined in the Generic Aging Lessons Learned (GALL, NUREG-1801 Rev. 01, [2]) report published by the U.S. Nuclear Regulatory Commission (NRC). The goal of this paper is to provide an overview of the work performed by AREVA NP Inc. to support the development of the MRP I&E guidelines and unit-specific AMP for UCB and LCB bolts. A review of Alloy A-286 and Alloy X-750 bolts in the B&W design PWR is provided including the degradation mechanism, operating and inspection experience, replacement, and autoclave and in-reactor test results. The latest UT inspection technique used to characterize the extent of flaws is also discussed. Acceptance criteria for evaluating degraded conditions in UCB and LCB bolts were developed in accordance with the requirements of the ASME Section III, Subsection-NG core support structures requirements. In addition to Code compliance, special limits were established to limit the change in the core support structure stiffness. The acceptance criteria enable utilities to rapidly disposition UT inspection findings during an outage within 48 hours. In order to support the objectives of an efficient AMP for the UCB and LCB bolts, three-dimensional finite element models were prepared capable of evaluating all potential failure scenarios. These models enable accurate representation of flange flexibility and redistribution of loads due to deficient bolts. Prior to an outage, hypothetical patterns of bolt failures could be evaluated to support pre-outage planning and contingency preparation. During an outage, these models are used to disposition inspection results and help operability assessment of continued operation, and re-inspection requirement to ensure continued safety and integrity of the reactor vessel internals. Based on the existing work performed, future improvement and expansion of analytical capability is outlined in the last section of this paper. In conclusion, AREVA NP Inc. has demonstrated an effective use of a multi-disciplined approach using structural analyses, operating experience, material evaluations, and non-destructive examination (NDE) to fulfill both the development and implementation of unit-specific aging management commitments as required by MRP-227 for the current and extended license periods.

Abstract:
Statistical data available from several international sources, such as the reports provided by the European institutions EGIG, CONCAWE and UKOPA, as well as by the American Department of Transportation – DOT, indicate that pipelines represent the safest mode of transportation for hydrocarbons and other dangerous products when compared to other alternatives, such as road, rail, waterway, etc. Operators ensure a high level of safety of their pipelines by investing large amounts of effort and resources in accident prevention, efficient contingency procedures, environmental protection and reliability along the life cycle of their assets. However, the pipeline industry, both in Brazil and abroad, is frequently asked to demonstrate their safety performance both by environmental and regulatory agencies, as well as by society, considering the assets already in operation and also those that will still be built (new pipelines). Such requests are based on the most opened and detailed communication between pipeline operators and the other stakeholders involved. In this context, the organized and standardized collection of data related to pipeline failure events, such as failure mechanisms and their consequences, along with relevant and specific data regarding the assets and their operations, is essential to foster the process of knowledge construction on this topic. It allows generating consistent information both to meet the stakeholders’ requests and to improve risk management of pipelines by the operators, ultimately supporting decision-making. Therefore, this work aims to create a Brazilian Pipeline Incident Database, considering firstly gas pipelines and oil pipelines operated by TRANSPETRO, a PETROBRAS Subsidiary. This research intends to study the characteristics, the architectures, the assumptions and the principles adopted by the international pipeline failure databases currently available, considered here as benchmarks, in order to propose an analogous and specific structure for the reality of the Brazilian Pipeline System.

Abstract:
Abstract A deviated newly drilled gas well in Western Caspian Sea in Azerbaijan, with a flowing water reservoir pressure of 17,500-psi and a flowing gas reservoir pressure of 12,200-psi was unable to regain flow after an unsuccessful attempt to bullhead produced water back into the well. During the bullheading operation, there was a peak registered pumping pressure of 12,933-psi without admission of fluid into formation. Producing interval was 5880mTVD with a MASP of 9,700-psi for gas reservoir. Coiled Tubing was the most viable option to identify the problem, to solve it and to regain access to the lower completion and then proceed with interval abandonment program. This being an unconventional well in multiple aspects, presented serious challenges accentuated in Safety, Well Integrity Control, Obstruction Removal, and Well Conditioning Plan Forward. Integrity of completion was believed to be compromised by the high pumping pressures applied during bullheading and a confirmed communication between production tubing and "A annulus". After performing 2 rig site visits, an action plan was issued to adjust the platform for a Coiled Tubing intervention for the first time. Points to be developed in the plan were HSE, Structural Analysis and modifications required for proper equipment accommodation. For well integrity control, it was imperative to evaluate the potential scenarios which could have led to the problematic well status. Completion history and specifications were reviewed to assure each of the potential operating scenarios could be controlled without compromising well integrity. On obstruction removal, simulation software was used to design procedure with optimum string, chemicals, rates and fluids to be used for the operation and which contingency fluids considered to be available offshore. It is challenging to perform effective cleanouts in completions with 2 different sizes of tubings (IDs 3.74" & 2.2") combined with restrictions (1.92" nipple), the success is a function of overcoming limited fluid pumping rates, slow annular velocities, particle sizes, cleaning speeds, among others. Well conditioning for future completion operations was planned depending on successful achievements of the coiled tubing intervention. A total of 14 runs with coiled tubing using different BHA configurations were performed to complete the scope. Well was safely and successfully cleaned from a starting depth of 2,512mMD to a target depth of 5,864mMD (5,610mTVD) by removing mud deposits, consolidated sand bridges and completion restrictions. Throughout the cleanout operation, best practices discussed on planning stage were applied to remove multiple obstructions encountered and dealing with potential corkscrewed casing. By accomplishing the well delivery, it is evident that the methodology followed during the planning stage and execution, was crucial to save the well from being lost or abandoned. There was an uncertainty whether the completion integrity was compromised by the high pressures used during the bullheading operation. Novelty in this intervention was the methodology for the risk assessment for an unconventional live well intervention with a 17,500-psi BHP, unseen pressure in the region. Thorough structural analysis was performed to assure the coiled tubing equipment could be placed safely on the platform to condition the well to regain production

Abstract:
Complex military operations often result in U.S. forces remaining at deployed locations for long periods. In such cases, more sustaina-ble facilities are required to better accommodate and protect forward-deployed forces. Current efforts to develop safer, more sustaina-ble operating facilities for contingency bases involve construction activities that require a redesign of the types and characteristics of the structures constructed, that reduce the resources required to build, and that decrease the resources needed to operate and maintain the completed facilities. The Automated Construction of Expeditionary Structures (ACES) project was undertaken to develop the capa-bility to “print” custom-designed expeditionary structures on demand, in the field, using locally available materials with the minimum number of personnel. This work investigated large-scale automated “additive construction” (i.e., 3D printing with concrete) for con-struction applications. This report, which documents ACES materials and testing, is one of four technical reports, each of which details a major area of the ACES research project, its research processes, and its associated results. There major areas include System Require-ments, Construction, and Performance; Energy and Modeling; Materials and Testing; Architectural and Structural Analysis.
