B a c k g r o u n d . The ordinary language philosophy should be considered as a set of different but interconnected research projects within the Anglo-American analytical philosophy of the first half and middle of the 20th century. A common factor for these studies is the application of the method of linguistic analysis of natural language expressions to solve many classical problems for philosophy. This method replaced the prevailing idealistic concepts, and was picked up and developed in Great Britain by the works and scientific explorations of J. Moore and B. Russell. It is a generally accepted opinion that the sphere of interests of representatives of the ordinary language philosophy is divided between two poles, represented by the works of L. Wittgenstein and D. Austin. M e t h o d s . In the article, the author used the method of historical-philosophical reconstruction to clarify the role, place and genesis of the ordinary language philosophy as a dominant methodology within the Anglo-American analytical philosophy of the middle of the 20th century, general scientific methods of cognition: analysis, synthesis, generalization to clarify key ideas and concepts, which is the basis of the methodology of the ordinary language philosophy, as well as methods of systematization and comparison. R e s u l t s . The article clarifies the genesis of the main ideas and concepts of the philosophy of everyday language, as well as gives an example of the modern strategy of criticism of this methodological direction. The key postulates of the ordinary language philosophy age are clarified, namely: (i) the thesis that philosophical problems arise due to the incorrect use of language and must be solved by clarifying the meanings of words, (ii) philosophical analysis should not be based on the discovery of hidden logical forms of expression, and on the clarification of the necessary and sufficient conditions for the use of the expression, including the analysis of the situation of use, (iii) meaning as use, (iv) the philosophical analysis of the meaning should be carried out informally, taking into account the analysis of each specific case of the use of the expression, (v) criticism systematic theories of meaning. C o n c l u s i o n s . At the current stage of the development of analytical philosophy, there is a noticeable increase in attention to the achievements of the ordinary language philosophy. Among modern researchers and critics of this direction, the names of A. Baz, D. Nagel, S. Somes, and T. Williamson can be singled out. The presence of the interest of modern researchers indicates premature statements about the completion of the ordinary language philosophy. This concept should be rehabilitated, and its methodological apparatus should enrich the arsenal of scientific methods of modern analytical philosophers.

Co-innovation and socio-technological niche development: The case of livestock farming on natural grassland in Uruguay

Achieving sustainable food and nutritional security requires a transformation of the existing agrifood system. In livestock farming based on natural grassland in Uruguay, an ecological intensification strategy could play a radical role in the transition towards more sustainable systems. This study analyzes the continuity of interconnected projects that used co-innovation approaches to promote and evaluate ecological intensification strategies over a period of 15 years (2004–2019). The purpose of the article is to provide evidence on the development of a socio-technical niche in sustainable livestock farming and to identify anchoring points for further regime transformation. Our contention is that interactive research in the context of application based on a sequence of co-innovation projects has the potential to trigger a sustainability transition through ecological intensification of livestock farming based on natural grassland. The research followed a single-case study design with multiple units of analysis, based on the study of documents produced by the different projects and semi-structured interviews. In addition, network analysis was used to examine the linkage of persons and projects. Results show that a socio-technical niche in sustainable livestock farming base on natural grassland was developed in Uruguay, promoted by research institutions and progressively involving other social actors throughout the process. The continuity of projects over 15 years, was fundamental to achieve the three essential processes for a niche conformation: i) an alignment of expectations and the development of a common vision, linked to the sustainable development of family-farming; ii) the creation and expansion of a network of stakeholders, comprising researchers, farmers, extensionists, and other relevant actors; iii) the development of learning processes through interaction, accumulating knowledge around two main axes: a new way of promoting innovation through research in application contexts associated with co-innovation, and a new way of sustainable livestock farming associated with ecological intensification. This study reveals the importance of sequencing co-innovation projects and continuity in the negotiation of visions of change, the creation of a community committed with the direction of change, and the promotion of interdisciplinarity and interactive learning, that foster changes at a socio-technical level. Anchoring challenges, and therefore advancement of the transition process, face the need for significantly expanding trained research and extension personnel to implement co-innovation and ecological intensification practices in livestock systems, and the organization of an extension program to sustain long term transformation of livestock farming in Uruguay.

Key Technology for Construction of Steel-concrete Composite Suspending Cofferdam without Bottom Cover for Platform of Coastal Intercommunication Project

<p>Many bridge piers were built in the Coastal Interconnection Project of the Ningbo Section of the Hangzhou-Ningbo Expressway Double Line. Affected by the tides at the bridge site, the high pile caps are constructed using a suspending cofferdam without a bottom cover. Based on the consideration of various factors such as construction difficulty, safety, cost and construction period, etc. A cement structure is generally adopted as the floor of the suspended box cofferdam. The steel-concrete combined hanging box cofferdam without bottom cover adopts the structure of steel wall plate and prefabricated cement floor, and the partition wall plates are connected by bolts. The steel-concrete composite suspending cofferdam adopts the prefabricated bottom plate and wall plate. The construction sequence is listed as follows: First, weld the load-bearing corbel on the steel casing, and then hoist the prefabricated bottom plate to the steel casing corbel in blocks. Pour the wet joint between the prefabricated bottom plate and install the side plate. After that, pour the cushion after welding the shear plate. Finally, carry out the construction of the cap. During the construction of the project, the connection method between the wall plate and the bottom plate was optimized. The connection of the fine-rolled rebar hanger rod was changed to the steel bar pair pulling, which improved the construction efficiency significantly.</p>

Kinematic-based landslide risk management for the Sichuan-Tibet Grid Interconnection Project (STGIP) in China

Landslides are major threats to the construction and operation of electric towers of the Sichuan–Tibet Grid Interconnection Project (STGIP). The long, narrow project corridor is vulnerable to different types of landslides, making risk management a difficult task. In this study, a kinematic-based, landslide risk management framework that includes hazard analysis, risk estimation, risk evaluation, and risk control is proposed and implemented. The spatial density of historical landslides and the spatial distribution of landslide kinematics are used to analyze landslide hazard. Kinetic energy derived from the landslide physical process model is employed to analyze the vulnerability of the towers in the risk estimation step. Then, the landslide hazard and tower vulnerability are used to comprehensively evaluate the landslide risk level of the electric towers. Electric towers with high risk are mainly situated in areas near rivers and faults, with fragile steep slopes. Fragmented rock masses and a thick regolith cover provide abundant materials for landslides, and steep slopes supply the initial conditions and energy that make them a risk. Risk-control strategies are provided based on site-specific risk. The safe construction and operation of the STGIP in the past 10 years show the effectiveness and reliability of the proposed framework. We suggest that the workflow and guidelines for landslide risk management used in this study can be adopted for large engineering projects in complex environments.

Unexpected collaborations: A science librarian and a reference archivist co-teaching

Libraries and archives are often grouped together as knowledge organizations with some shared goals and purposes, and in academic institutions this is no different. They might compete for the same resources or be managed by the same administrative teams; however, how much collaboration is there between libraries and archives in academia? Some might suppose that there is consistent collaboration and interconnected priorities and projects which foster that collaboration. Those librarians providing support for historians or history departments may have strong working relationships with reference archivists, but what about those working in other areas of librarianship? Would there be opportunity, for example, for an academic science librarian to partner with a reference archivist to elucidate the treasures hidden within archives relevant to scientists? We can definitively answer that question from our own personal experience. Since 2018, the authors, a science librarian and reference archivist, have worked together to introduce those beyond history departments the opportunities for archival research. In this column, we describe how we started working together, our various collaborative efforts over the years, and what we have learned along the way.

Integration of an exploration program with its parent organization: A lifecycle perspective

Exploration programs are collections of interconnected exploration projects that are identified, coordinated, and managed in order to pursue a strategic objective of exploring radical innovations to be developed by the parent organization. Based on a longitudinal fine-grained study of a firm that has launched such an initiative, we offer a characterization of an exploration program and outline the coexistence of its integration with, as well as its isolation from, its parent organization. This is achieved through mechanisms and boundary activities complementing each other and undertaken by actors involved in the program and located at different levels of the parent organization. We show how this integration with the parent organization evolves between the program initiation and its implementation and how the differences lie in its exploratory nature, i.e., the definition of its scope, which is not known at its launch, the potential leveraging of the firm's existing resources to execute the exploration projects and then to further develop them, and the capitalization on the projects’ outcome and the use of the knowledge that has been built in excess.Thus we further bridge the literature on project and program management with the literature on innovation management and show how an exploration program can contribute to achieving ambidexterity at the firm level.

About the New Methodology and XAI-Based Software Toolkit for Risk Assessment

There are different approaches in different areas of what the risk is. ISO 31000 risk management standards describe risk as the effect of uncertainty on objectives. Many existing risk assessment procedures are based on the assumption that risk is the amount of any damage or loss multiplied by the probability of an event that could cause the damage. We are proposing a new risk approach, based on Hillson’s positive risk philosophy, that risk is not just a threat but also a composition of new opportunities, efforts that need to be put in, and uncertainty. For this approach, we composed a risk formula and a methodology based on that formula. A prototypical software tool was developed, and an experiment was performed using this tool to evaluate the risk of several interconnected projects and validate the developed risk assessment methodology. It should be mentioned that, in the methodology, the decision-making process is performed traceably; therefore, it can be stated that it has explainable artificial intelligence (XAI) traits.

MANAGEMENT CONTROL IN THE PROCESS OF IMPLEMENTATION OF INNOVATION PROJECTS

The scientific publication is dedicated to highlighting the systemic vision of the basics of management controlling in the process of implementing innovative projects and revealing the features of this type of controlling. It has been established that controlling the process of implementation of innovative projects is a special type of controlling, associated with their individuality and the absence of analogs and established patterns of analysis and control, and with the uncertainty of the final results of the project, its individual stages. It is substantiated that the control process is a process of step-by-step correction of expected project results, gradual control of parameters as the final result is approached. The procedure for determining the coefficient of change in the speed of work, which characterizes the execution of the network or operational-calendar schedule at the time of control, is considered. It is proposed to determine the relationship between the informational importance of control points and the implementation coefficient based on the value of the financial “penalty” function. The matrix of information weights of control points is considered, which is the basis for determining the sequence of polling points (objects) of control. The procedure for determining the step (control lag) for two interconnected innovative projects during the technological rehabilitation of production is revealed. The distribution function or the probability of the absence of uncertainty in the process of implementing works on the implementation of an innovative technological project before the moment of control is determined. Options for choosing the frequency of control point polls for operational management are substantiated. It was established that from the point of view of the stability of the information system, the algorithm for determining the maximum frequency of checks on the status of project implementation work should take into account the possibility of falling behind the given schedules and reducing the amount of remaining work, which results in an increase in the number of control point surveys. The limit of the increase is the time required for the implementation of decisions on operational regulation of the speed of work execution by production divisions (executors).

Modelling low carbon electricity generation of an integrated ASEAN power grid

In 1997, 10 economies of the Association of Southeast Asian Nations (ASEAN) established the ASEAN Power Grid (APG), a cross-border interconnection network that effectively uses regional energy resources. This study aims to quantify the effect of ASEAN power grid interconnection on electricity exports-imports between south-east Asia economies and its implications for renewable energy shares and carbon emission in power generation. Three scenarios are assessed in this model. The Base Scenario simulates APG parameters in 2030, considering four existing interconnections and those interconnection projects currently under construction. The second scenario, HAPUA Scenario, includes all the future interconnection projects outlined in the HAPUA report. The carbon tax scenario as the last scenario, aims to evaluate whether carbon pricing policies in Southeast Asia may incentivise cleaner energy and renewable energy development in the region. Under the HAPUA Scenario, Indonesia increases coal and/or gas-fired generation for electricity exports, contributing to a slight increase in CO2 emissions from power generation for the ASEAN region. It appears that carbon price affects the choice of electricity generation and incentivise cross-border electricity trade. Under the carbon tax scenario, emissions will decline to 719 MtCO2 or 22% lower than the base scenario and 24% than the HAPUA scenario.

Load Flow Study of Togo and Benin Transmission Power Network by the Newton-Raphson Method

Within the framework of the Economic Community of West African States (ECOWAS) countries power networks interconnection project carried by the West African Power Pool (WAPP), operating guidelines have been defined by WAPP and ECOWAS Regional Electricity Regulatory Authority (ERERA) to ensure efficient operation of the interconnected network. Each operator is obliged to comply with these directives to guarantee the stability and reliability of energy supply to ECOWAS countries. The purpose of this paper is to carry out the study of the power flow on the existing Togo and Benin power transmission network and to propose solutions for compliance with the requirements relating to the voltage level required on the interconnection lines or at connection points with neighboring power network operators. The dynamic stability of generators will also be studied to assess the behavior of the network during major disturbances. CEB (Communauté Electrique du Bénin in french) is the power transmission network operator of the Republic of Togo and the Republic of Benin. After the inventory of CEB transmission and production infrastructure and the consumption report, the model of CEB power network is produced as well as the single-line diagram. The power flow calculation is performed with the Newton-Raphson algorithm and the node voltages were calculated using the Cyme software. From the voltage values obtained at the various nodes and depending on the behavior of each generator, solutions are proposed to improve the voltage plan of the power network in accordance with the recommendations of the Regulatory Authority.

Comparison between different territorial policies to support intermodality of public transport.

As an important part of sustainable mobility, intermodality aims at improving the efficiency and attractiveness of a travel made by different means of transport, resulting in a seamless experience for travellers. The Inter-Connect Project was set up as a study to reduce environmental impact caused by motorised transport, thus enhancing sustainable mobility of passengers. The whole analysis developed through the creation of integrated connections among different transport modes - road, rail, and sea transport considering different factors related to sustainability such as social (quality of life, transfer safety and comfort), economic (efficiency, employment, productivity) and environmental factors (emissions, biodiversity, environmental protection). The study was realized in the ADRION area developing different solutions aimed to promote transport integration among partner States: Albania, Bosnia Herzegovina, Croatia, Greece, Italy, Montenegro, Serbia, Slovenia. The cooperation between the partner states led to align some goals and policies, to share knowledge, data and resources, between different institutions and organizations. To this end, the study methodology followed a bottom-up approach to ensure each entity involved was willing to cooperate, in order to overcome any legal, infrastructural, and operating barriers, and to supply the best intermodal solutions to facilitate passengers. Potential improvements introduced to promote intermodality in the eight Inter-Connect study cases were examined from a transnational, national, and regional point of view to identify their strengths and weaknesses. Each partner of the Inter-Connect Project developed their projects thus enhancing and promoting the use of intermodal transport modes for passengers.

Leveraging a Population-Based Dyadic Data Set to Promote Health Equity Among Chinese Americans

Recognizing the central role of family-oriented values in Chinese culture, developing a family-based understanding of health and wellbeing in Chinese Americans is imperative. By linking two unique population-based datasets (one on Chinese older adults, and another on their corresponding adult children caregivers), the purpose of this symposium is to present interactive analyses of dyad-level data to achieve an interpersonal understanding of health outcomes of Chinese older adults and their adult children within the family context. Data were obtained from 807 Chinese older adults-adult children dyads by merging data from two epidemiological studies, namely the Population Study of ChINese Elderly in Chicago (the PINE study) and the PIETY study of corresponding adult children caregivers of PINE participants. Specifically, this symposium presents findings from five interconnected research projects. Session 1 provides an overview of study design and sample characteristics of the dyadic dataset. Session 2 examines the relationship between adult children’s endorsement of the filial piety value and older parents’ mental health outcomes. Session 3 investigates the level of congruence between older parents’ self-perceived mental health and adult children’s evaluation of their parents’ mental health. Session 4 investigates the extent to which depressive symptoms among older parents were associated with those of their adult children. Session 5 explores the relationship between older parents’ physical function and adult children’s perceived caregiving burden. Taken together, this symposium presents potential contributions of dyad-level analyses in advancing minority population health. Study findings have the potential to inform the development of family-centered intervention strategies targeting Chinese Americans.

THE MULTI-CRITERIA PLANNING MODEL OF URBAN SPATIAL DEVELOPMENT WITH REGARD FOR THE INTERESTS OF STAKEHOLDERS

Abstract. The present study is aimed at supporting the concept and making the model of urban spatial development as a complex architectural town-building and socio-economic system, as well as developing tools for reaching agreed multi-criteria planning decisions in the interests of stakeholders. The study examines basic theories (such as pattern language and central places) and conceptual approaches to the formation of urban spaces of trade, recreational, healthcare, image, entertainment, environmental, and sports character. It reveals the possibility and substantiates the necessity of employing expert methods and methods of project management for analysing, generalising, and modelling of urban civic space planning. In addition, there search substantiates conceptual principles, sets out general requirements, and highlights the main tasks of decision-making planning. Furthermore, a multi-criteria optimization model has been built to plan urban spaces in conditions of contradictory interests of stakeholders, under limited resources and in complete in formation. The implementation of the model is to increase the validity of planning decisions and, as a result, lead to higher standards of living due to expansion of existing and diversification of potential functions of urban public spaces. For the evaluation of architectural urban building, economic, social, cultural-monumental, and ecological results, the study lays down criteria depending on the extent the plan of urban public space development is put into action.The method of successive concessions has been shown as an efficient tool for reaching agreed co-created planning decisions by stakeholders. The provided basic model of reaching optimum planning decisions satisfying certain criteria contains restrictions on potential urban spatial development, as well as on the sequence in which interconnected development projects are carried out, and on the balance between supply and demand for services (functions) of urban public spaces. The model, which has been modified by the method of successive concessions for achieving agreed planning decisions in the interests of stakeholders, is based on establishing a dominant optimization criterion, on expert justifying of allowable optimality losses against initial planning decisions per criterion at each stage of subsequent calculations, and on reaching a consensuson a final decision. Keywords: public space, a planning decision, spatial development, evaluation criteria, development potential, a model, interests of stakeholders, a co-creation method.

Combining the characteristics of the reverse distribution of solar resources and water resources in North Africa, West Africa and the Sahara, this paper proposes the West Africa-North Africa grid interconnection project to realize the optimal configuration of desert solar resources and surrounding water resources, and introduce the water resources of West Africa's Niger River and North Africa's desalinated seawater to improve the living environment and development conditions in the hinterland of the Sahara Desert; build photovoltaic bases along the route to send clean electricity to North Africa and West Africa. This paper studies the transmission channel path, electricity-water composite transmission technology and project scheme, and analyzes the economics of the project and the water supply and demand conditions of the Niger River. The research results show that it is feasible in hydrological characteristics to lead the Niger River water along the power transmission channel that crosses the Sahara Desert, and the new electricity-water composite transmission technology has obvious economic advantages.

An Optimal Design of a Small Photovoltaic Plant with Cost Minimization based on a Real Database of PV Panels and Inverters

The penetration of renewable energy sources and the development of autonomous power systems for the supply of isolated consumers find applications such as covering energy needs in lighthouses, small islands, monasteries, and even isolated special industrial facilities. Power plant cost is a major limitation in the development of these systems. For example, although the electromechanical cost of photovoltaic plants has been significantly reduced in recent years, however the land cost is not considered, which is a significant expenditure. In this paper, the real problem of an autonomous power station design for the supply of the shoreline electrode substation on the Stachtorroi islet of Attica, is taken as the starting point. The electrode substation is part of the Attica-Crete high voltage direct current (HVDC) electrical interconnection project. For the above problem, an overall evaluation algorithm for a photovoltaic (PV) plant is proposed that considers the technical characteristics of the plant, the installation and operating costs (including land costs in addition to electromechanical costs and efficiency of each of the plants components), as well as the actual commercial data of the individual key elements (PV panels, inverters) of various companies, choosing the optimal system through exhaustive search depending on the required power and the deflated capital reduction interest rate

AN ONE BELT, ONE ROAD AND THE WORLD: HOW CHINA IS MASTERING THE WORLD'S MIGRATION PATTERNS

This study looks at China's "One Belt, One Road" initiative, which is grouped into two parts: the Maritime Silk Road Initiative and the Silk Road Economic Belt, both of which were revealed in 2013. Through the establishment of interconnected infrastructure projects such as ports, roads, railways, and pipelines, each component has the ability to reshape the global geopolitical landscape.The paper is divided into four sections to help the reader have a better grasp of the OBOR project and its impacts. This study describes trends and patterns of recent OBOR projects in Belt and Road Countries, analyzes the geopolitical implications of the OBOR, and investigates the integration of new migration patterns based on existing data and literature on current Chinese development. Using a geopolitical approach that identifies territorial and political power, This study examined prospective migration and integration patterns that may emerge as the OBOR initiative advancements. As a result, this paper concludes that the OBOR initiative is not only an international cooperation project, but something that also turns China's geopolitics power at various levels, has the potential to be momentous, and will simultaneously create opportunities for global partnership while also reshaping the existing migration pattern and a new geopolitics perspective.

Study on Local Sediment Scour and Stress State of Submarine Cables in Offshore Wind Farms

The laying of submarine cables will destroy the local seabed topography, leading to changes in the submarine hydrodynamic boundary, which will cause the local unbalanced sediment transport phenomenon when the submarine cable is buried. When the submarine cable begins to be exposed or the topography changes greatly, the scour phenomenon will be more severe. This article starts from the safety and stability of the submarine cable during the operation and maintenance of the 200MW offshore wind farm in Xuwen Wailuo, Guangdong Province, China and refers to the partial scour of the submarine cable in the “Southern Main Grid and Hainan Power Grid Second Interconnection Project” near the site near the Qiongzhou Strait. In this case, the measured ocean hydrological data at the site is used as the input condition, and Fluent is used to establish a refined hydrodynamic model of the submarine cable scour, to simulate the development process of the submarine cable scour of the wind farm under real sea conditions, and to perform the force analysis after the submarine cable is exposed. These will provide a certain scientific basis for ensuring the safe and stable operation of submarine cables during wind farm operation and maintenance.

Complementarity of clinical trials, model systems, and metabolomic workflow to unravel the healthy effects of foods: BEBESANO vs MODELSANO: A case study

Nowadays, the health benefits associated with the consumption of plant-based food constitute a hot topic. To further demonstrate such benefits, related to antioxidant, anti-microbial, and anti-inflammatory activities, as well as the reduction of the risk of several pathophysiological conditions, the study of bioaccessibility and bioavailability of specific food’s constituents, which require interdisciplinary networks, is essential. In this frame, although different experimental models can be developed, the workflow described in the present work support the application of intervention trials in humans as the first option to study the truly effects on health of foods (e.g., plant-based foods), due to the safe condition of them and the realistic approach of this kind of studies, later explored in depth resorting to in vitro, ex vivo, and pre-clinical models, as the most appropriate workflow to get reliable results in the field of Food Science and Nutrition, regarding mechanisms of actions and molecular interactions. Thereby, the work described in the present review is developed in the frame of two consecutive and interconnected projects: BEBESANO (concluded) and MODELSANO (in process) that demonstrate the efficiency of the workflow proposed for research in the Food Science and Nutrition fields. In this regard, in the frame of BEBESANO, acute and longitudinal interventions in humans, devoted to set-up bioavailability of bioactive compounds, followed by functional studies in vivo upon pre-clinical models were conducted to unravel the relationship between bioactive compounds in plant-based beverages and the use of sweetener replacer. Now, most relevant findings from BEBESANO are being further explored in the newly granted project MODELSANO, which is aimed to uncover gaps of knowledge about the mechanisms behind the descriptive results obtained in BEBESANO, using more restrictive in vitro models (allowing the development of studies on the cellular and molecular pathways involved), and integrative cutting edge mathematical modelling alternatives. Keywords: In vivo; in vitro; bioavailability; bioaccessibility; bioactivity; health-promoting foods; metabolomic; mechanistic studies

Interconnection viability of high demand isolated area through a HVDC-VSC link

Electrically isolated areas are separated by a great distance and, normally, have a considerably low demand; in consequence, these are non-interconnected from the main power grid or electrical national transmission systems. Great distance and low demand are the reasons why an interconnection project in high voltage AC is not feasible in most of these cases. Nevertheless, there are some isolated areas with high power demand and even though they are separated from the main grid by large distances and hard terrains; however, it is still reasonable to think about an interconnection project. This paper had developed a methodology that allows the evaluation of viability, technically and economically, of a HDVC-VSC interconnection project for great distance and high demand considering overhead and/or underground DC line. The methodology was applied to a case of study in Peru, based on the projected interconnection between Moyobamba and the isolated area of Iquitos; showing that HVDC is a feasible alternative.

The up- and downside of collaboration in core and non-core technologies – Selective, contingent, and orchestrated openness in R&D collaborations

This paper contributes to the current debate about the “knowledge sharing-protecting” tension in R&D collaborations by introducing a new angle for analyzing this paradox. Considering the role of internal knowledge sources of the firm, the paper introduces and empirically analyses the interplay between three knowledge governance mechanisms (selective, contingent, and orchestrated openness) and the different technological fields of the firm (core, related non-core, and distant non-core technologies). Based on a unique first-hand large-scale project-level dataset from a Global 100 firm across a 10-year span, this research finds that R&D collaborations selectively conducted in firm’s related non-core technological fields promise the best innovation performance. Further, by orchestrating its projects across core and non-core technological fields in the same knowledge portfolio, the firm can leverage a network of inter-connected projects when collaborating with external partners. As such, the firm can strategically “distribute” collaboration risks across multiple projects, while optimize its access to external knowledge that it intends to get. Finally, contrary to the common assumption, this study does not find any discriminating factors against market-based partners in their contribution to innovation in both core and non-core technologies.
