This paper explores how competition works in knowledge ecosystems, using a theory elaboration approach. With little research conducted in this area to date, three strategic streams of thought—resource-advantage theory, dynamic capabilities framework, and adaptive marketing capabilities perspective—are compared as a departing point and a frame of reference regarding the dynamics of competition. The streams of strategic thought all converge around the notion that organizations must constantly renew themselves to adapt and align to a fast-changing marketplace. The characteristics of knowledge ecosystems are conceptualized, whereafter an in-depth case study is presented to empirically assess competition in knowledge ecosystems, focusing on the perspective of a keystone actor. At the ecosystem-level, knowledge ecosystems primarily expose and explore knowledge, indicating that they mostly operate in a pre-competitive state. The time needed and the limited control inherent to knowledge exploration translate into the keystone actor focusing on transient rather than sustainable competitive advantage. Knowledge ecosystems further prove to be central in the coevolution and the growth of other ecosystems through connecting and sharing of the explored knowledge base with other ecosystem actors who, in turn, exploit this knowledge common for commercial purposes and innovation.

This article conceptualises The Australian as the nation’s ‘keystone media’ on Indigenous affairs. Nielsen’s term ‘keystone media’ captures the critical importance of particular news outlets that play what he terms an outsize role in defining the state and structure of wider media and political environments. The article analyses the factors at play in The Australian’s sponsorship of a particular political agenda for this complex field of social policy. The argument is illustrated through an examination of Indigenous health coverage from 1988 to 2008, textual analysis of 137 columns written by Noel Pearson, and research interviews with key actors in the Indigenous policy realm, including journalists, public servants and Indigenous commentators. Through this examination of its reporting and collaboration with Pearson, we contend The Australian has advanced a range of neoliberal and interventionist policies to government and the public.

Purpose The purpose of this paper is to understand value cocreation in service ecosystems from a multilevel perspective, uncovering value cocreation factors and outcomes at the micro, meso, and macro levels. Design/methodology/approach A Grounded Theory approach based on semi-structured interviews is adopted. The sample design was defined to enable the ecosystem analysis at its different levels. At the macro level was the Portuguese Health Information ecosystem. Embedded meso level units of analysis comprised eight health care organizations. A total of 48 interviews with citizens and health care practitioners were conducted at the micro level. Findings Study results enable a detailed understanding of the nature and dynamics of value cocreation in service ecosystems from a multilevel perspective. First, value cocreation factors are identified (resource access, resource sharing, resource recombination, resource monitoring, and governance/institutions generation). These factors enable actors to integrate resources in multiple dynamic interactions to cocreate value outcomes, which involve both population well-being and ecosystem viability. Study results show that these value cocreation factors and outcomes differ across levels, but they are also embedded and interdependent. Practical implications The findings have important implications for organizations that are ecosystem actors (like the Portuguese Ministry of Health) for understanding synergies among value cocreation factors and outcomes at the different levels. This provides orientations to better integrate different actor roles, technology, and information while facilitating ecosystem coordination and co-evolution. Originality/value This study responds to the need for a multilevel understanding of value cocreation in service ecosystems. It also illuminates how keystone players in the ecosystem should manage their value propositions to promote resource integration for each actor, fostering resource density and ecosystem viability. It also bridges the high-level conceptual perspective of Service-Dominant logic with specific empirical findings in the very important context of health care.

Abstract The participation of residents in development processes is a keystone in current rural governance arrangements. The European Union’s rural development program LEADER is an example of this, as it requests local residents to take action in the development process. Similarly, participatory forms of natural and cultural heritage preservation have increased significantly with the aim of revitalizing the socioecological fabric of territories. Following the Anthropology of Policy, the study employs an ethnographic approach to analyze the effects of bio-cultural heritage preservation strategies in the context of LEADER. Drawing on ethnographic data gathered during several field observations and semi-structured interviews in a LEADER region in North Rhine-Westphalia, the article investigates how a local LEADER initiative reconstructs a historical cultural landscape in order to valorize and exploit the biocultural heritage resources of their village. Residents articulate four interrelated senses of (be)longing while (re)making the biocultural heritage: 1) Political claim to use a resource; 2) place attachment; 3) politics of in/exclusion; and 4) nostalgic-utopian longing. As new knowledge actors in landscape governance, residents posit their perceptions, interpretations and valuations of the landscape vis-à-vis institutional actors of landscape governance and negotiate large-scale landscape transformations in the region investigated.

Purpose To understand why the penetration of handset-based mobile payment in most countries is still low has been an important research topic for the last 15 years, and it has been analyzed from different perspectives. However, the analysis of a single aspect cannot provide a sophisticated answer to the complicated underlying question. The purpose of this paper is to understand how a relatively successful m-payment ecosystem is created and sustained through the coopetition of various actors. Design/methodology/approach To that end, the authors analyze the case of Alipay wallet, the m-payment service provider with the largest market share in China, and focus on understanding the motivations and subsequent actions of the organizations cooperating in the Alipay wallet core ecosystem. Findings The results show that actors with heterogeneous and complementary resources can forge sustainable collaboration. Within an ecosystem, although always constrained by resources and capabilities, the actions that the core actors take and the resulting power imbalances are dynamically changing, reflecting actors’ aim of reducing uncertainty. Research limitations/implications The main limitation of this case is that it was conducted in a Chinese context, which has specific features that may not apply to other cases. In addition, this study is based on a single case study in a single country, without comparing the results to any other cases or countries. Therefore, some modifications may have to be made when applying the framework and generalizing the results. Practical implications With regards to the practical perspective, the Alipay case may serve as an example that other providers follow, taking similar actions to increase the dependency of others and reduce their own dependency on others. It is helpful to take a keystone strategy to create value within the ecosystem and share this value with other participants. Moreover, Alipay acts as the platform provider, in addition to managing value creation within the ecosystem and sharing that value with the other participants. Alipay focuses on the business and strategic needs of the core actors, without threatening their main business, for example, Alipay focuses on micro-payments, which does not pose a direct competition to banks, who mainly rely on macro-payments to generate profit. Micro-payments are often related to high transaction costs for banks. In addition, although it is difficult to define the boundaries of actors in the ecosystem, the core business of every actor is the key competitive or even survival condition. This notion should be taken into consideration by actors whose actions affect the business of other ecosystem partners. For instance, Alipay will not aim to become a bank, as they know that if they do so, they cannot connect any other bank to their platform. In other words, the scope and boundary of the actors are clearly identified so that the core business will not be threatened. Sords, we can learn from Alipay that it pays off to focus on one area, and not to let your competitors challenge you. Originality/value The authors proposed the StReS framework for analyzing a business ecosystem by combining resource-based review, resource dependency theories and network analysis for investigating the motivations of the organizations cooperating in the core ecosystem and the actions they have taken to reduce dependency and uncertainty.

The evolution of China’s international investment surge has been analyzed critically over the years, but we still know relatively little about its effect on developing countries. In turn, sub-Saharan African countries have a longstanding history of foreign influences that have had a deeply rooted effect on their people’s sentiment. This research continues to fill the gap regarding how Chinese investment decisions and the underlying intentions are perceived at the local level in Western Africa. For this research, the focus lies on entrepreneurs from Sierra Leone, given the country’s unique economic climate in Western Africa and the position of entrepreneurs as keystone actors toward local innovation, and thus, local economic development. This focus resulted in the following research question: How do entrepreneurs in Sierra Leone perceive Chinese influences regarding Sierra Leone’s local economic development? To answer this open research question, rich data was collected by means of interviewing local entrepreneurs in Freetown, Sierra Leone. Altogether, both comparable and contrasting perceptions on Chinese influences regarding Sierra Leone’s local economic development are presented, resulting in the expansion from an initial thinking model toward an extended thinking model.

The trouble with groundwater is that despite its critical importance to global water supplies, it frequently attracts insufficient management attention relative to more visible surface water sources, irrespective of regional climate, socioeconomic profile, and regulatory environment. To this end, the recently defined sub-discipline of “socio-hydrogeology”, an extension of socio-hydrology, seeks to translate and exchange knowledge with and between non-expert end-users, in addition to involving non-expert opinion and experience in hydrogeological investigations, thus emphasising a “bottom-up” methodology. It is widely acknowledged that issues pertaining to groundwater quality, groundwater quantity, climate change, and a poor general awareness and understanding of groundwater occurrence and movement are global in their scope. Moreover, while effective communication and engagement represent the key tenet of socio-hydrogeology, the authors consider that multiple actors should be identified and incorporated using stakeholder network analysis and may include policymakers, media and communications experts, mobile technology developers, and social scientists, to appropriately convey demographically focused bi-directional information, with the hydrogeological community representing the communication keystone. Accordingly, this article aims to highlight past and current work, elucidate key areas of development within socio-hydrogeology, and offer recommendations to ensure global efficacy of this increasingly important and growing field going forward. The authors seek to assist in protecting our global groundwater resource for future generations via an improved framework for understanding the interaction between communities and hydrogeological systems.

Workflows are the keystone of bioimage analysis, and the NEUBIAS (Network of European BioImage AnalystS) community is trying to gather the actors of this field and organize the information around them. One of its most recent outputs is the opening of the F1000Research NEUBIAS gateway, whose main objective is to offer a channel of publication for bioimage analysis workflows and associated resources. In this paper we want to express some personal opinions and recommendations related to finding, handling and developing bioimage analysis workflows. The emergence of "big data” in bioimaging and resource-intensive analysis algorithms make local data storage and computing solutions a limiting factor. At the same time, the need for data sharing with collaborators and a general shift towards remote work, have created new challenges and avenues for the execution and sharing of bioimage analysis workflows. These challenges are to reproducibly run workflows in remote environments, in particular when their components come from different software packages, but also to document them and link their parameters and results by following the FAIR principles (Findable, Accessible, Interoperable, Reusable) to foster open and reproducible science. In this opinion paper, we focus on giving some directions to the reader to tackle these challenges and navigate through this complex ecosystem, in order to find and use workflows, and to compare workflows addressing the same problem. We also discuss tools to run workflows in the cloud and on High Performance Computing resources, and suggest ways to make these workflows FAIR.

Global industries are characterized by complex networks of organizations, which are often dominated by a few disproportionately large transnational corporations. While industry consolidation is not a new phenomenon, the scale and speed at which global industries now impact diverse social-ecological systems is unprecedented. In this thesis, I combine the interconnected perspective of business ecosystems with the sustainability focus of the social-ecological systems literature through the concept of keystone actors. Adopting a network perspective, I apply this framing to the global clothing industry, and specifically analyze the patterns of coordination and collaboration among actors working to address systemic sustainability challenges facing the industry. While keystone actors wield significant influence over both the industry’s biophysical and socio-economic impacts, I find it is the presence of key brokers – actors who mediate indirect connections between keystone actors in the clothing industry – that possess the potential to coordinate action around sustainability challenges into a collective industry-wide effort. I conclude the thesis by discussing how the empirical findings, and network perspective more generally, can advance the study of keystone actors in global business ecosystems.

<i>Abstract</i>.â€â€The Lake Trout <i>Salvelinus namaycush</i> is a keystone species in the Laurentian Great Lakes that supported valuable fisheries throughout the basin until the 1950s. However, Lake Trout populations declined to near extirpation in nearly all of the lakes by the 1960s because of the combined effects of overfishing, Sea Lamprey <i>Petromyzon marinus</i> predation, and habitat degradation. To restore self-sustaining Lake Trout populations in Lake Superior, state, provincial, federal, and tribal agencies agreed to an interjurisdictional management framework that allowed them to articulate and institute (1) clear and common goals and actions for recovery, (2) early and intensive lakewide stocking of hatchery-reared Lake Trout to enhance failing stocks, (3) early and effective lakewide controls on mortality caused by Sea lampreys and fisheries, and (4) standardized lakewide evaluations of population trajectories and performance. Stocking was initiated in Lake Superior in 1950 and expanded after 1953, prior to effecting Sea Lamprey or fishery controls, thereby introducing large numbers of hatchery-origin fish that grew to maturity shortly after mortality was reduced. Abundant suitable nearshore spawning habitat was widely available for naive lean hatchery-origin Lake Trout, and native lean Lake Trout persisted in some areas. The Sea Lamprey-selective pesticide TFM (3-trifluoromethyl-4-nitrophenol) was applied first in Lake Superior in 1958 because of the presence of remnant native Lake Trout populations, which set the stage for closure of fisheries and good survival of newly stocked and remnant wild fish. As a consequence of these four factors, stocked fish exceeded historical density of wild fish by the 1980s in many areas and thereby generated enhanced reproductive potential when combined with remnant wild fish. Lake Trout recovery in Lake Superior is an extraordinary example of agency cooperation toward a common goal for managing recovery of an ecologically important shared resource.

This Chapter considers the keystone rule, the non-frustration rule and its operation and effect in the context of hostile takeovers. The Chapter first explores the scope of the rule to determine what steps target boards can and cannot take when faced with a hostile offer. It considers the general meeting approval of frustrating action and explains why in practice such approvals are never seen. The Chapter then proceeds to consider the optimality of the rule. It considers first the roots of both the Panel’s and more general public support for the rule, arguing that commitment to the rule is a function not of the policy balance between the advantages and disadvantages of the rule but rather a function of broader and deep structural understanding of the balance of power in a UK company. It is a commitment whose genesis is historically contingent which should, if possible, be discounted in the policy assessment of the advantages and disadvantages of allowing target boards to defend against unwanted takeovers. The Chapter then proceeds to consider this policy balance in a UK context which involves, inter alia, a consideration of: the extent to which defences can be used to entrench a board which is subject to pro-shareholder UK company law; the extent to which the market for corporate control acts a governance mechanism; and modern fund management behaviour influenced by relative performance metrics which supports a claim that defences can be justified in order to protect ultimate shareholders from their fund managers, a nuance on the standard justification that defences protect shareholders from themselves. The Chapter concludes that the policy case for prohibiting takeover defences is weak, and moves to consider the reform options in light of the post-Cadbury and Kraft debate on this issue. The Chapter considers and supports both reform of the non-frustration rule (by abolishing the rule) and a higher acceptance threshold (which effectively enables shareholders who are interested in long term fundamental value to make the decision). But the Chapter rejects disenfranchisement of short-term shareholders and enhanced public interest test. The Chapter concludes that it is now time for the Panel to engage with the broader consequences of the rule and reform options.

Abstract Circular economy aims to address limited resources through the continuous circulation of materials and energy. Recirculating low quality materials for reuse is a sustainability goal that is analogous to the primary function of Nature’s detritus species, a keystone for the proper functioning of ecosystems. Prior applications of ecosystem structure to human network design uncovered that even the most economically successful networks of industries demonstrate a lack of analogous detritus actors in the form of reuse and recycling. The recycling industry’s volatile nature, dependency on international factors, and financial difficulties prevent this strategy from becoming an efficient alternative. Creativity in design, inspired by ecosystems, is proposed here as a method to repurpose manufacturing byproducts that are otherwise seen as low quality waste materials. Realizing the reuse potential of these materials can create detrital-type feedback loops, an attribute that supports the characteristic resilience and efficiency of ecosystems. The work here analyzes existing methods of pursuing circular economy and investigates the potential benefits generated by purposefully adding connects that create detrital-feedback-loops at the consumer and producer levels.

Within the framework of the Latvian National Programme EKOSOC-LV this paper focuses on the smart growth as a tool for regional development. The research aim is to evaluate the factors that influence the formation of a smart territory and to estimate interconnections of quantitative indicators and expert opinions. The present study reflects the quantitative and qualitative assessment of smart growth challenges in the region of Latgale (Latvia) on the level of 19 districts. One of the most important aspects of the implementation of the concept of smart specialization is the participation of all involved actors; thus, one of the solutions of smart growth evaluation is the multiple helix approach. By analysing and summarizing the aspects affecting smart territories, based on the theoretical principles, regional stakeholder’s (local governments, entrepreneurs, representatives of communities, scientists, general public) recommendations, taking into account the national strategic settings and the views of the EKOSOC-LV working group, smart growth index was developed as well as factor hierarchy of the smart territory formation and growth, on the basis of which the Analytic Hierarchy Process method was realized. Logical construction, monographic, analytic hierarchy process, statistical analysis methods are used for research. The quantitative assessment is based on integrated index (Smart Development Index) establishment and testing. The qualitative assessment is based on the regional expert opinions summarized by the Analytic Hierarchy Process methodology. Complex analysis of the obtained quantitative indicators highlights the People and Resources dimension, but qualitative assessment underlines People and Economy dimensions as the keystones of the smart specialization of the Latgale region. The integrated application of quantitative and qualitative approaches allows a comprehensive assessment of the smart growth process in the Latgale region and its districts.
