The purpose of this study was to explore the strategising practices of chartered accountants (CAs) in the South African mining industry. Few studies have dealt with the practical skills CAs employ when they engage in strategising practices and, in particular, a gap could be identified on how CAs engage with strategy tools during strategising. Approximately two thirds of all directors in South Africa are CAs and only 11% of directors who are CAs also hold master‟s degrees in business administration. The question then arises of how do CAs engage with strategy tools during strategising? This study applied key concepts of social practice theory to explore the strategising practices of CAs from a strategy-as-practice perspective. The strategy-as-practice perspective entails studying strategy practitioners within their social constructs. The context of this study was the South African mining industry, a landscape seen as an essential part of the South African economy. An exploratory qualitative research design was applied whereby one-on-one interchanges during individual interviews provided rich, detailed descriptions of how CA strategists use strategy tools when they engage in strategising practices. The social nature of the practices and praxis of strategy practitioners from a strategy-as-practice perspective constantly changes. As such, the current study was conducted from a constructivist paradigm to describe the narrative reality of the strategy practitioners as they engage with strategy tools. The findings of the study portrayed participants as bricoleurs of strategy tools, i.e. craftspeople who adapted and interpreted strategy tools from an accounting perspective to serve the requirements of the situation they face. / Financial Accounting / M.

Increasingly, researchers on strategy are turning away from the highly abstracted and de-humanized components that seem to typify the macro approach to strategy. This movement is at least partially brought about by a philosophical recognition that the emergent and unpredictable nature of organizational life is fast exposing the constraints of an approach to strategy that is based on the values of rationality, predictability and control. In this thesis I argue that organizational change in general and the act of strategizing in particular can be thought of as a social, transformative and emergent process as opposed to the overly orderly, rational, formative and/or humanistic views on strategy presented by systemically oriented theorists. I draw on the theory of complex responsive processes of relating as espoused by Stacey, Griffin and Shaw (2000) and specifically on Stacey’s (2003, 2007) substantial contribution to the field of strategic management. By utilizing a reflexive research methodology I describe the arduous social and emergent process of transformation in my practice and identity (observable in subtle changes in disposition, language and assumptions) as I begin to act into the understanding of strategizing as an ongoing, incomplete, social process. In doing this, I am suggesting that the narrated accounts of our shifts in practice due to us knowing differently are important contributions in the process of transforming our theories on and beliefs around strategy. These accounts should not be seen as premature attempts at methodological frameworks, but rather as explorative participation in the emergent transformation of a radical, social approach to strategizing. I engage critically with the notion of strategy-as-practice and suggest a review of the fundamentally rational and formative assumptions still prevalent in the work of researchers like Johnson, Melin and Whittington (2003) and Samra- Fredericks (2003). Whilst acknowledging the role of culturally mediated dispositions in the ongoing transformation of organizations advocated by Chia and Holt (2006) and Chia and MacKay (2007), I argue for the paradoxical and therefore simultaneous occurrence of habitual and mindful actions by people strategizing as opposed to the authors’ suggestion of a predominantly mindless experience of organizational change. Finally, I turn to Stacey’s (2007) question as to why people continue to make long-term forecasts if their usefulness is so obviously limited. Whilst understanding his frustration, I argue that there is value nevertheless in engaging in strategy making albeit not for the rationalist reasons usually stated. In my view the real value of strategising is to be found in two areas: first in the social activity that goes into creating these documents, and second: the documents not only serve as markers in an ongoing process of strategising; they also give us a way of ‘going on’ and taking the next step.

Acknowledging the difficulties of achieving effective strategic management in practice, this thesis investigates how formal strategies quite often succeed in conditioning organisational actions even in firms such as professional service firms, which may lack effective measures for coercing action and which often depend on distributed decision-making. The fundamental question posed in this investigation is: what are the social processes that make strategies work? This thesis addresses that question by contributing to our understanding of strategy realisation as a continuing process of translating formal strategies into ‘strategies-in-practice’, i.e. the situated performance of strategies through choices, actions, and practices pertaining to the selection and accomplishment of concrete assignments. The thesis investigates this translation process in three small professional service firms, in which the responsibility for enacting the strategies lies with autonomous practitioners, making centralised strategy realisation difficult. Searching for integration rather than further fragmentation of different strands of strategy research, the thesis make use of Porterian activity systems theory, Giddens’ structuration theory, Wittgensteinian theory of rule-following, Searlean theory of intentionality, and the strategy-as-practice approach, in order to understand the translation process as the intentional structuration of practice. The thesis reports two main contributions, the first addressing a gap in strategy re-search, the second contradicting prevailing theories. The first contribution is an outline of a theory of strategy translation: how formal strategies are translated into strategies-in-practice, coping with insoluble strategic dilemmas, and achieving maintenance of strategic position and strategies-in-practice under pressure for unwanted change. Good strategies-in-practice are as much about managing dilemmas as about eliminating them. Second, in contrast to prevailing strategic positioning theory and generic strategies, this study documents the potential benefits of straddling strategically distinct services within a single activity system, in terms of: learning opportunities; work variation; better opportunities for attracting, developing, and retaining talented people; the possibilities of capitalising on client relationships; and the dynamics of routinisation of once-novel services.

Esta pesquisa teve como objetivo compreender como os sujeitos organizacionais praticam a estratégia a partir de processos de gestão estratégica e de comunicação que visam coordenar sua ação laboral em torno de um quadro de significados compartilhado para alcance de objetivos institucionais. Para isso, parte de um referencial teórico sobre comunicação fundamentado nos estudos interacionistas - principalmente pelos trabalhos de Mead, Blumer, Goffman, Quéré e França - articulados com a teoria da prática, de Bourdieu, e da estruturação, de Giddens, que ajudam a compreender a vinculação entre indivíduos, organizações e sociedade. Para apresentar os esforços de gestão da comunicação organizacional, entendidos como prática de relações públicas, discutiram-se os desafios impostos pela busca por legitimação organizacional das organizações contemporâneas e como o pensamento estratégico tem se desenvolvido para, inclusive, dar conta desse objetivo. Em contraposição aos estudos clássicos da estratégia, que a tomam pela perspectiva gerencial, assume-se como núcleo teórico a Nova Teoria da Estratégia, proposta por Pérez e Massoni, que fundamenta a estratégia na comunicação, articulada com a corrente da estratégia como prática trazida, dentre outros, por Whittington, Golsorkhi, Jarzabkowski e Orlikowski. Para contextualização das análises, situa-se o objeto nas discussões sobre gestão pública e comunicação públicas contemporâneas, descrevendo o processo de implantação da gestão por resultados e do choque de gestão em Minas Gerais. Assim, para tratar da especificidade da implementação do Balanced Scorecard (BSC) na Secretaria de Fazenda de Minas Gerais (SEF/MG), elegeu-se uma abordagem metodológica de natureza qualitativa, com estudo de caso único, baseada na hermenêutica de profundidade proposta por Thompson e na Análise Crítica do Discurso, por Fairclough. Após pesquisa institucional que trouxe as principais definições estratégicas e esforços formais de comunicação da instituição, analisou-se o material por ela produzido, sobre sua estratégia, pautado nos princípios do Balanced Scorecard e da comunicação mobilizadora, buscando evidenciar os modos como a Fazenda interpela seus servidores no intuito de criar um quadro de significados compartilhado que oriente suas ações para o alcance dos seus objetivos corporativos. A prática da estratégia foi analisada a partir da observação de treze reuniões de Avaliação de Desempenho Estratégico (ADE), realizadas no 3º trimestre de 2013. Considerou-se como eixos de análise a caracterização dos praticantes da estratégia (os estrategistas da SEF/MG), das práticas que envolvem a gestão estratégica (local, recursos tecnológicos, humanos e simbólicos) e da prática situada da reunião de ADE como prática comunicativa (já que social e discursiva) da Fazenda. Propõe-se, assim, uma matriz conceitual para defender a indissociabilidade entre comunicação e estratégia, possibilitando situar as ações estratégicas (essencialistas ou práticas) e comunicacionais (transmissivas ou relacionais) das organizações, de modo a fomentar a reflexão crítica sobre elas. O estudo demonstrou que, na SEF/MG, a metodologia de gestão da estratégia - o BSC - está alinhada com a concepção da estratégia enquanto essência. No entanto, enquanto o BSC se estrutura em torno da possibilidade de que o conteúdo da estratégia, elaborado pela cúpula organizacional, seja transmitido ao corpo dos funcionários, a noção de comunicação mobilizadora é relacional. A defesa da tese é que análises dessa natureza sejam valorizadas como contribuição relevante ao estudo e prática da comunicação e da estratégia nas e das organizações, evidenciando, não os resultados do alinhamento dos sujeitos organizacionais em relação à estratégia (eficácia dos processos), mas, antes, os quadros sígnicos acionados e como eles participam da ação dos sujeitos que, recursivamente, reforçam ou negociam os significados propostos pela organização. / This research has as its objective to understand how the organizational actors practicize the strategy, through the processes of strategic management and of communication that aim at coordinating their labor action within a frame of shared meanings in order to reach the institutional goals. It is grounded by a theoretical reference on communication interaction studies - mainly those of Mead, Blumer, Goffman, Quéré and França - that we articulated with Bourdieu\'s practice theory and Giddens\' theory of structuration, that help us comprehend the links between individuals, organizations and society. In order to present the efforts of organizational communication management, understood as Public Relations practice, it has been discussed the challenges related to the searching of organizational legitimacy by contemporary organizations and how the strategic thinking has evolved to be up to those challenges. As counterpoint to the classic studies of strategy, that take it through the management perspective, we assume as a theoretical center the New Theory of Strategy, as proposed by Pérez and Massoni, that fundaments the strategy in communication, articulated with the current of Strategy as Practice, mainly as in the works of Whittington, Golsorkhi, Jarzabkowski and Orlikowski. Seeking the analysis contextualization, we situate the object in our discussions of contemporary public management and communication, describing the process of implementing the management by results and the management shock in Minas Gerais. In doing so, and in order to treat the specificities of the implementation of the Balanced Scorecard in the Secretaria de Fazenda de Minas Gerais (SEF/MG), we have elected a qualitative methodological approach, with a single case study, based on the depth hermeneutics proposed by Thompson and on the Critical Discourse Analysis, by Fairclough. After the institutional research that brought to light the main strategic definitions and formal communication efforts of the institution, we have analyzed the material it has produced about its strategy anchored by the principles of the Balanced Scorecard and of the mobilizing communication, searching to put in evidence the ways that Fazenda interpellates its employees in order to create a shared frame of meanings that guides their actions towards the fulfillment of its corporative objectives. The practice of strategy has been analyzed through the observation of thirteen meetings of Strategic Performance Evaluation (SPE) that have taken place in the 3rd trimester of 2013. It have been considered as analyses axis the characterization of the strategy practitioners (the strategists of SEF/MG), of the practices that involves the strategic management (local, technological, human and symbolic resources) and of the practices situated in the SPE meetings as a communicative practice (since social and discursive) of the Fazenda. It is proposed, with that, a conceptual matrix to defend the impossibility of dissociating communication and strategy, making it possible to situate the strategic actions (whether essentialist or practical) and the communicative actions (whether transmitted or relational) of the organizations, in a way to foment the critical thinking of them. The study has shown that, in SEF/MG, the methodology of strategic management - the BSC - is aligned with the concept of strategy as an essence. However, while the BSC structures itself around the possibility of the transmission of the strategic content, elaborated by the higher organizational players, to the board of employees, the notion of mobilizing communication is relational. The theses defends that analyses of this nature must be seen as a relevant contribution to the study and practice of communication and of strategy in and of the organizations, putting in evidence not the result of the alignment of organizational actors in relation to the strategy (the efficacy of the processes), but, instead, the meaning frames activated by the actors and how they participate of the action, as they, recursively, reinforce or deny the meanings proposed by the organization.

Assim, esta tese tem como objetivo central analisar a estratégia como prática e a sua relação com a liderança solidária compartilhada desempenhada entre os sujeitos dos empreendimentos econômicos solidários, associados a uma central de cooperativas atuante no campo da reciclagem de resíduos sólidos urbanos. O método é orientado pela perspectiva etnográfica, objetivando a descrição densa dos dados coletados por meio de 15 entrevistas semiestruturadas com os coordenadores da central, 48 diários de campo realizados por meio da observação participante e análise do corpus documental de 27 documentos coletados. O período de realização da pesquisa foi de março de 2013 a julho de 2015. Os resultados apontam para um sistema complexo de relações sociais implicados pelos conflitos internos e externos ao grupo e que materializam processos de busca por consensos. Esses processos acontecem no espaço gerencial da central, permitindo que a estratégia como prática ocorra e contribua com o desenvolvimento da liderança solidária compartilhada, descentralizando as atividades e projetando o alcance dos resultados do empreendimento. / The analytical effort focused on the thesis is the process of developing strategy as a practice, as well as the phenomenon of shared solidarity leadership, in the context of solidarity economy. Thus, this thesis aims to analyze the strategy as a practice and its relationship with shared solidarity leadership developed among the subjects of solidarity economic enterprises associated to a cooperative center, which acts in the field of urban solid waste recycling. The method is guided by the ethnographic perspective, aiming at describing the data collected through 15 semi-structured interviews with the coordinators of the center, 48 field research journals made through participant observation and the documentary corpus analysis of 27 collected documents. The research period was from March 2013 to July 2015. The results point to a complex system of social relations implied by the group’s internal and external conflicts that materialize processes of search for consensuses. These processes take place in the central management space, allowing the strategy as a practice to occur and contributing to the development of shared solidarity leadership, decentralizing the activities and projecting the achievement of the results of the enterprise.

Esse setor é composto em 96% por empresas de micro e pequeno porte, as quais surgem a partir de conhecimento técnico dos empreendedores, porém com deficiências em gestão (STEFFANUTO, 2004), o que acarreta o encerramento de 35,9% antes de completarem cinco anos de atividade (SEBRAE, 2007). Esta dissertação tem por objetivo identificar e descrever como ocorre o processo de administração estratégica em uma pequena empresa do setor de Tecnologia da Informação, com base no estudo das escolas de estratégia apontadas por Mintzberg et al. (2000), e também a partir da visão de estratégia como prática social apontada por Clegg, Carter e Kornberger (2004), Jarzabkowski (2003, 2004, 2005), Whittington (2001, 2004) e Wilson e Jarzabkowski (2002, 2004). Para desenvolver a pesquisa, foi adotado o método de estudo de caso de uma empresa classificada como de pequeno porte, inserida no setor de tecnologia da informação. Os dados analisados revelaram que a empresa pesquisada adota uma administração estratégica informal e centralizada na diretoria. Observou-se que esse modelo de administração estratégica é especialmente similar ao modelo descrito por Mintzberg et al. (2000) como a escola empreendedora e baseado na visão do empreendedor. Entretanto, os dados também apontam a presença de características de outras escolas de estratégia ao longo do ciclo de vida da empresa pesquisada, como a escola de Design, de Posicionamento e também as escolas de Aprendizado, a Cultural e a Cognitiva. A estratégia é comunicada em parte aos colaboradores a partir de formalização em um evento anual, e continuamente pela percepção por intermédio do padrão de comportamento organizacional. Foi evidenciada a presença da estratégia como prática social no nível estratégico (diretoria), analisando-se a trajetória e a atual gestão estratégica da empresa. Também foi analisada a estratégia na prática em nível tático, junto à gestão intermediária, por intermédio de suas orientações, suas interações com clientes e fornecedores, sua tomada de decisões, entre outras práticas ligadas ao cotidiano dos gerentes. Por fim, a dissertação apresenta, a partir dos dados da pesquisa, outras lacunas para pesquisas futuras sobre o tema, além de uma série de sugestões para a empresa pesquisada. / The information technology sector in 2006 accounted for 8.3% of Brazilian GDP, demonstrating its importance to national economy (IBGE, 2009). The sector is composed of 96% for micro and small businesses, which arise from technical knowledge of entrepreneurs, but with deficiencies in management (STEFFANUTO, 2004). Those deficiencies lead to the closure of 35.9% before completing five years of activity (SEBRAE 2007). This dissertation aims to identify and describe how the strategic management process occurs in a small company in the sector of Information Technology. It is based on the study of schools of strategy outlined by Mintzberg et al. (2000), and also from the strategy vision as social practice pointed out by Clegg, Carter and Kornberger (2004), Jarzabkowski (2003, 2004, 2005), Whittington (2001, 2004) and Wilson and Jarzabkowski (2002, 2004). To develop the research it was adopted case study method. It was studied a firm classified as small business, inserted in the sector of information technology. The analysis showed that the company adopts an informal strategic management researched centered on the board. One noted that this model of strategic management is especially similar to the model described by Mintzberg et al. (2000) as the entrepreneurial school and based in the vision of the entrepreneur. However, data also indicate the presence of features of other schools of strategy throughout the life cycle of the company studied, such as the School of Design, Positioning and the schools of Learning, Cultural and Cognitive. The strategy is communicated in part to employees from formalization into an annual event, and continuously by the perception through the pattern of organizational behavior. The presence of strategy as social practice at the strategic level (directors) was made evident, analyzing the history and the current strategic management of the company. Also one discussed the strategy in practice at the tactical level, near the middle management, through their guidance, their interactions with customers and suppliers, its decision-making, among other practices related to the daily lives of managers. Finally, the dissertation, based on survey data, presents some gaps for future research on the subject, plus a series of suggestions for the company studied.

This approach receives contributions of philosophy (pragmatism) and social sciences, appropriating the concept of social practice and applying it to studies of management. It also benefits from contributions coming from the Carnegie Tradition, Neo-Institutional Theories, Situational Learning and Actor- Network theory. Through discourse analysis of nine interviews with strategists and executives from midsize businesses, it presents a typology of stages that combines and clarifies aspects of the strategizing from the practitioner s point of view. In this sense, uses excerpts from the speech of interviewees, taking advantage of the main themes addressed by them as evidence of the constituent aspects of each stage / Estudo de cunho exploratório e qualitativo sobre o processo estratégico, segundo abordagem que entende a estratégia como uma prática. Essa abordagem recebe contribuições da filosofia ( pragmatismo) e das ciências sociais, apropriando-se do conceito de prática social e aplicando-o aos estudos da gestão. Beneficia-se também das contribuições oriundas da Carnegie Tradition, das teorias neo- institucionais, da aprendizagem situacional e da teoria ator-rede. Através da análise do discurso de nove entrevistas com estrategistas, executivos de médios negócios, apresenta uma tipologia em estágios que agrega e esclarece aspectos do processo de fazer estratégia, do ponto de vista de seus praticantes.

The literature review on emerging concepts of 'Business model' and 'Business model innovation' finds significant theoretical and practical potential to facilitate the strategising and innovating activities of modern organisations operating in complex and dynamic business environments. However, a further review of extant literature reveals that although a significant knowledge-base has been accumulated focusing on the content and process aspects of the phenomenon, very few of the conducted studies take a practice-based perspective. Therefore, in keeping with the broader research question of current strategising practices, this research investigates the issue from many possible philosophical, theoretical and methodological angles, in turn making several contributions to the theory and practice of business models while also opening up several potential future research avenues. This research consists of four main research stages sequentially covering problem formulation, two theory creation phases and problem solving, thereby meeting the requirements of a practice-based management research through relevance rather than merely rigour, as in conventional scientific research. As a result, it offers several research contributions to both the theory and practice of business models, which can be immediately put into practice by theorists, practitioners and entrepreneurs: a pluralistic business model research classification framework; a dynamic practice-based approach to the construction of business models; a knowledge-based conceptualisation of business models and a dynamic capability matrix for business model practices. Additionally, this research also offers potential future contributions to adjacent research streams such as dynamic capabilities, strategy as practice and research methodology. Overall, by utilising the philosophy of pragmatism, this thesis advances the contemporary discipline of business models towards a practice-based science, crucially and timely bridging the knowledge gap in existing practice-based theories and frameworks business models. It is hopes that this work will gave rise to a new movement of research on business models, positioning itself as a well established applied-oriented management science among the broader disciplines of strategy, innovation and entrepreneurship.

Un consensus général existe dans la recherche en Systèmes d’Information (SI) autour du concept et du modèle d’alignement stratégique (SAM) développé par Henderson et Venkatraman (1993). Celui-ci offre une norme technique et managériale pour un choix et une gestion optimale, puisque rationnelle, des SI. Paradoxalement, de nombreux projets de reconfigurations SI sont des échecs et entrainent les entreprises dans des trajectoires d’escalade d’engagement. A partir d’une lecture critique de la littérature construite sur les principes de la stratégie par les pratiques (SasP), nous cherchons à décrire les dynamiques organisationnelles à l’origine de la réussite ou de l’échec de ce type de projets. Une étude qualitative a été menée à travers quatre cas et une étude Delphi dans une approche de théorie enracinée. Ce corpus de données a fait l’objet d’un codage assisté par le logiciel NVivo. A travers la mobilisation de la théorie de la traduction, l’analyse des données a fait émerger une perspective alternative de celle défendue par la littérature traditionnelle. Une situation d’alignement est le résultat de la constitution d’un réseau de trois pôles parties prenantes aux projets, à savoir le pôle utilisateurs, le pôle managérial et le pôle technique. Ce réseau n’existe pas en soi, il est une construction collective liée à l’adhésion de ses membres sur la base de la satisfaction de leurs besoins respectifs à travers un processus de traduction. Nous ne parlons plus d’alignement stratégique, ni d’alignement des SI, mais d’alignement d’intérêts des parties prenantes autour d’un projet SI. / In information systems (IS) research, there is a solid consensus in acknowledging Henderson’s & Vankatraman’s (1993) concept and model of strategy alignment. It provides a rational technical and managerial standard for optimal choice and management of SI. Paradoxically, many IS reconfigurations are failures and entail firms to go into an escalation of commitment. Based on a critical reading of the literature built on the principles of strategy as practice, (SasP), we seek to describe the organizational dynamics behind the success or failure of such projects. Through four cases and a Delphi study, a qualitative analysis was conducted using a Grounded Theory approach. This body of data underwent coding with the assistance of the software NVivo. Through the use of translation theory, data analysis has given rise to an alternative perspective to that advocated by the traditional literature. A state of alignment is the result of the establishment of a 3-pole project stakeholder network, i.e. the managerial pole, the users’ pole and the technical pole. This network does not exist in itself; it is linked to a collective adherence of its members on the basis of the satisfaction of their individual needs through a translation process. We no longer speak of strategic alignment or IS alignment, but of the stakeholders’ alignment of interests around an IS project.

Quelle différence faisons-nous entre Leroy Merlin, Castorama ou encore Bricorama ? Ces organisations se distinguent par un ensemble d’attributs qui façonnent le caractère unique, leur identité. Ce travail de recherche propose de mieux comprendre comment se forme l’identité d’une organisation. Il appréhende la question identitaire sous le prisme du courant de la stratégie comme pratique et la théorie de l’identité organisationnelle. Afin de répondre à la problématique de recherche, la thèse questionne le rôle des parties prenantes, des pratiques et de la matérialité sur le processus de formation de l’identité organisationnelle. L’originalité de ce travail réside dans l’étude de la formation identitaire dès la création d’un intermédiaire de l’innovation dans le secteur de la construction. La recherche repose sur un cas unique longitudinal à dimension ethnographique. Elle inclut une enquête sur la perception des parties prenantes externes de l’identité de l’organisation.Les résultats mettent en évidence le rôle prépondérant des fondateurs mais aussi des salariés dans la formation identitaire. Le cas d’un intermédiaire de l’innovation fait émerger une stratégie de formation de l’identité organisationnelle, le jeu identitaire. Il correspond à l’exploration de plusieurs futurs possibles. De plus, trois pratiques pour « former, réparer, maintenir, renforcer ou réviser » sont mises en évidence. Enfin, les résultats soulignent les effets de l’absence d’un artéfact (une plateforme physique) qui contribue à exacerber le conflit sur l’identité entre les membres.Ce travail de recherche présente aussi des implications managériales visant à comprendre comment former et gérer l’identité au cours du temps. / What difference do we make between Leroy Merlin, Castorama or Bricorama? These organizations are distinguished by a set of attributes that shape their uniqueness, their identity. This research proposes to better understand how organizational identity is formed. The identity question is addressed by taking a strategy as a practice lens and is grounded in organizational identity theory. In order to answer the research question, the thesis is interested in the role of the stakeholders, practices and materiality on the organizational identity formation process. The originality of this work lies in the study of identity formation from inception of an innovative intermediary in the construction sector. The research is based on a unique longitudinal case with an ethnographic dimension. It includes a survey of the perception of external stakeholders about the organization’s identity.The results highlight the preponderant role of founders but also of employees in identity formation. The case of an innovation intermediary reveals a strategy to form organizational identity: organizational identity play. It corresponds to the exploration of several possible futures. In addition, three practices for "forming, repairing, maintaining, strengthening, or revising" identity are highlighted. Finally, the results highlight the effects of the absence of an artifact (a physical platform) that contributes to exacerbate conflict over identity among members.
