Framing strategy under high complexity: Processes and practices of ongoing reframing in the becoming of strategy

Framing is a key concept in research on how strategists legitimize and win support for strategic change by establishing a frame of reference for that change. This article advances research on strategy framing by showing how, under conditions of high complexity and uncertainty, strategists continuously reframe strategy in relation to shifting constellations of stakeholders. It presents the findings of an ethnographic study of strategizing in the highly complex context of the digital transformation journey of a global manufacturing firm. It shows how (re)framing practices are combined to iteratively shape strategy formation in ways that sustain strategic influence in the face of constant threats to legitimacy. By accounting for how (re)framing practices reach back and forth in time, the ethnographic findings refine the conventional understanding of how framing resources of past strategizing enter and reworked in present strategy work. Finally, the article contributes empirical insights into how information systems specialists, often marginalized as strategic actors, frame and pitch strategic projects to gain and exert influence in strategy formation processes.     

Conserving complexity: A complex systems paradigm and framework to study public relations’ contribution to grand challenges

Sustainable development poses a grand challenge for society, addressed by organisations through their public relations activities. Grand challenges are complex by nature and call for nontrivial solutions whose effects show at the level of society. That is why studying public relations’ contribution to grand challenges requires a macro perspective that accounts for the dynamic interaction between individual, organisational, and system levels in a digital communication environment. This paper offers a new paradigm to analyse organisations’ significant and at times undue impact on grand challenges through public relations. It develops a framework inspired by complex adaptive systems thinking and adopts its ten properties for public relations: emergence, adaptivity, heterogeneous actors, nonlinear effects, feedback mechanisms, self-organisation, phase transitions, networks, scaling, and cooperation. The paper applies the framework to the example of sustainable development. It shows why research on grand challenges requires a holistic perspective and how it can help study digitally born communication phenomena. The proposed complex systems paradigm provides space for critical, social scientific, and interpretative research lines in public relations. Inquiries start from the grand challenge and study the communicative interactions between organisations and other actors from existing theory while accounting for the ten properties of complex adaptive systems. The paper outlines how future research can enrich the study of public relations and discusses its limits.     

New media and cultural disconnect: A study on the lodha tribal community of India

A qualitative study was undertaken among Lodha tribals in the Mayurbhanj district of Odisha to examine how digital media accessibility has affected the social and cultural life of the youths of this tribal community. It also assessed any interrelationship between new media existence and cultural exclusion among the youths. Face-to-face interviews, focus group discussions, and observation methods were applied for accessing and generating information. Five villages with more than 70 percent Lodha population were selected for the study. A stratified random sampling method was used to determine the sample. The results directly link new media consumption and cultural disconnect among the Lodha youths. The young tribals were moving away from their traditional cultural systems into a more urbanized existence that is far removed from the life known to their previous generations.     

基于DEM的地形因素在城镇土地定级中的量化——以通化县城区为例

在城镇土地定级中地形地貌因素对土地质量空间分布产生着深刻的影响。以土地定级技术为依托,结合通化县城区土地定级,采用GIS手段,建立区域DEM数据模型,以坡度、坡向数据模型的建立及量化为例,提出地形因素在城镇土地定级中量化应用的新方法。按照城市规划对地形的要求,利用栅格数据空间分析功能,快速求取海量栅格单元的要素作用分及其总分,对地形地貌因素进行科学量化,揭示基于地形地貌因素定级下的城镇土地质量空间分布差异性规律。     

DEPA数据安全规则解析及对中国的启示 ——基于和CPTPP/USMCA/RCEP的比对

构建数据安全规则是推进全球数字贸易治理的重要关切,中国申请加入《数字经济伙伴关系协定》(DEPA)后,需要在RTAs框架下,基于数据安全视角对DEPA 进行规则解析。采用自然语言识别法梳理DEPA数据安全规则体系,针对数据安全核心议题——跨境数据自由流动、数据存储非强制本地化、个人信息保护等,结合“特定规则”和“一般性规则”分析,通过文本比较评析DEPA和CPTTP、USMCA、RCEP等既有协定在这些议题上的覆盖范围、承诺深度的趋同和分歧。研究认为,DEPA针对跨境数据自由流动和数据存储非强制本地化所构建的规则,在推动数据流动自由化和保留自主监管空间两方面都处于中游水平; DEPA的个人信息保护覆盖范围比较广泛,特别强调数据保护可信任标志的使用。中国申请加入DEPA能够推动中国和DEPA在数据流动等议题上进一步确定和磋商,推进中国参与国际层面规则构建的进程、完善国内法律法规的有关规制,对中国申请加入CPTPP乃至其他RTAs协议的谈判都有积极作用,能够提高中国在数字贸易治理中的国际影响力。     

Closer than ever: Growing business-level connections between Australia and Europe

Despite the growing presence of European firms in Australia and vice versa, studies of these business-level connections have been few and far between. Building on points made in our earlier macro-level analysis of Australian-European relations, this study examines business-to-business and business-to-consumer activity at the micro-level between the two continents.We focus on three themes illustrative of these growing business-level relations. First, we examine the different pathways taken by Australian businesses in their quest to develop a European market presence. Second, we discuss instances of business and technological innovation in the Australian context, including stories of success in digital innovation and university-corporate collaboration as well as cautionary tales for European institutions arising from the Australian experience. Third, we compare and contrast how Australian and European businesses have responded to the challenge of climate change, focussing on the issues of green lending and retail insurer performance.In foregrounding these three themes, we offer reflections on the implications and lessons for the growing number of businesses operating across both continents.     

Industrial digitalization. A systematic literature review and research agenda

This paper addresses the recent growth in publications on the topic of digitalization by systematically reviewing the literature dealing with this major technological and organizational transformation in the manufacturing sector. Our aim is to enhance the understanding of this phenomenon and provide a critical account of the state of the art of the research on industrial digitalization. After summarizing the different conceptualizations of digitalization and the stages of its evolution, we identify four thematic areas (technologies, impacts, enabling factors, and barriers) and create a meaningful segmentation of the existing publications along these dimensions. We then develop a future research agenda on industrial digitalization at both a conceptual and an empirical level, encompassing the following themes: (i) the need for a more nuanced conceptualization; (ii) the potential evolution of one or more digital technologies toward the category of “general-purpose technology”; (iii) the search for new contingency approaches; (iv) the development of accurate models of inter-firm collaboration among digital manufacturers; and (v) the elaboration of suitable solutions able to guarantee the compatibility of industrial digitalization with ethical and sustainability principles.
