- Research on coopetition has been conducted for more than two decades. However, several concepts remain that require elaboration. A study on the literature shows that there is a lack of unified definitions, as various definitions have been employed in previous accomplished research. In this article we suggest that the early definition of coopetition, as a dual relationship between firms that simultaneously cooperate and compete needs to be refined. Our new definition suggests that coopetition is a paradoxical relationship between two or more actors, regardless of whether they are in horizontal or vertical relationships, simultaneously involved in cooperative and competitive interactions. We also highlight important contributions to the field, and some shortcomings that point to future challenges for coopetition research. Finally, we put forward five directions for future research: (1) understand the balancing of cooperation and competition, (2) understand the coopetition paradox and engendered tension, (3) apply a multilevel perspective on coopetition (4) understand the dynamics of coopetitive interaction, and (5) understand how coopetition impacts business models and strategy.

- The neural cell adhesion molecule (NCAM) is required for cell type segregation during pancreatic islet organogenesis. We have investigated the functional consequences of ablating NCAM on pancreatic beta-cell function. In vivo, NCAM(-/-) mice exhibit impaired glucose tolerance and basal hyperinsulinemia. Insulin secretion from isolated NCAM(-/-) islets is enhanced at glucose concentrations below 15 mM but inhibited at higher concentrations. Glucagon secretion from pancreatic alpha-cells evoked by low glucose was also severely impaired in NCAM(-/-) islets. The diminution of insulin secretion is not attributable to defective glucose metabolism or glucose sensing (documented as glucose-induced changes in intracellular Ca(2+) and K(ATP)-channel activity). Resting K(ATP) conductance was lower in NCAM(-/-) beta-cells than wild-type cells, and this difference was abolished when F-actin was disrupted by cytochalasin D (1 muM). In wild-type beta-cells, the submembrane actin network disassembles within 10 min during glucose stimulation (30 mM), an effect not seen in NCAM(-/-) beta-cells. Cytochalasin D eliminated this difference and normalized insulin and glucagon secretion in NCAM(-/-) islets. Capacitance measurements of exocytosis indicate that replenishment of the readily releasable granule pool is suppressed in NCAM(-/-) alpha- and beta-cells. Our data suggest that remodeling of the submembrane actin network is critical to normal glucose regulation of both insulin and glucagon secretion.

The coopetition paradox and tension in coopetition at multiple levels
- 2014

- This article explores the nature of the paradox inherent in coopetition; that is, the simultaneous pursuit of cooperation and competition between firms, and emanating tensions that develop at individual, organizational, and inter-organizational levels. We dissect the anatomy of the coopetition paradox to discover how it materializes by creating an external boundary (i.e., via unifying forces) and internal boundaries (i.e., via divergent forces). After explaining the coopetition paradox, we distinguish tension from paradox and submit that tension comprises both positive and negative emotions simultaneously, also known as emotional ambivalence. Finally, we recognize that emotional ambivalence in coopetition prevails at different levels, and vary in its level of intensity and persistency in relation to different contexts. We employ illustrative cases to ground our propositions empirically. This article provides understanding on concepts, expects to incite fruitful dialogue, and fuels further studies on inter-firm paradoxes.

Governance of Career Guidance : an enquiry into European policy
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The overall aim of this thesis is to enquire into and problematize the governance of career guidance and how individuals’ career management is constructed within EU policy. The empirical material consists of European policy documents produced during 2000-2015. The two central research questions explore (1) how European career guidance is made governable, and (2) how individuals’ career management is constructed and governed. The Foucauldian governmentality perspective and the analytic method of problematization is utilized. The analysis focuses on the compositions of normative forms of reason, discursive practices and techniques by which governing is exercised and knowledge is produced. The thesis is based on four articles, three of which concern career guidance and career management. The fourth article concerns education of citizenship. The analysis shows that the formation of a policy space for comparison of national systems of career guidance is significant for making European career guidance amenable to governance. It is mobilized by governing practices for involvement of institutional actors and the construction of standards of performance. This form of governance becomes effective on the condition that institutional actors use and produce knowledge and practices about what works in career guidance, and this implies self-control and constant monitoring. It is a complex process of producing self-regulation of career guidance adjustable to change and innovation in which both standardization and modulation are inbuilt. Moreover, this is dependent on the interplay of governance and self-government. Knowledge and practices shape career management as an individual competence, which each individual is assumed to achieve. The use of guidance techniques supporting this design and self-regulating practices contributes to responsibilizing individuals to achieve this competence. Knowledge of individuals’ management of their careers includes civic competence. This led me to extend my use of the theoretical framework to investigate how knowledge of civic competence is constructed in European policy documents concerning teacher education from 2000 to 2012. My analysis shows that presumptions of teaching civic competence support the production of the active and learning subject.

Improved Success Probability with Greater Circuit Depth for the Quantum Approximate Optimization Algorithm

Tidskriftsartikel (refereegranskat)abstract
- Present-day, noisy, small or intermediate-scale quantum processors-although far from fault tolerant-support the execution of heuristic quantum algorithms, which might enable a quantum advantage, for example, when applied to combinatorial optimization problems. On small-scale quantum processors, validations of such algorithms serve as important technology demonstrators. We implement the quantum approximate optimization algorithm on our hardware platform, consisting of two superconducting transmon qubits and one parametrically modulated coupler. We solve small instances of the NP (nondeterministic polynomial time)-complete exact-cover problem, with 96.6% success probability, by iterating the algorithm up to level two.

Nondegenerate parametric oscillations in a tunable superconducting resonator
- 2018

Tidskriftsartikel (refereegranskat)abstract
- We investigate nondegenerate parametric oscillations in a superconducting microwave multimode resonator that is terminated by a superconducting quantum interference device (SQUID). The parametric effect is achieved by modulating magnetic flux through the SQUID at a frequency close to the sum of two resonator-mode frequencies. For modulation amplitudes exceeding an instability threshold, self-sustained oscillations are observed in both modes. The amplitudes of these oscillations s how good quantitative agreement with a theoretical model. The oscillation phases are found to be correlated and exhibit strong fluctuations which broaden the oscillation spectral linewidths. These linewidths are significantly reduced by applying a weak on-resonant tone, which also suppresses the phase fluctuations. When the weak tone is detuned, we observe synchronization of the oscillation frequency with the frequency of the input. For the detuned input, we also observe an emergence of three idlers in the output. This observation is in agreement with theory indicating four-mode amplification and squeezing of a coherent input.
