PurposeThe purpose of this paper is to explore the emotional dynamics of the corporate acceleration process, using the systems psychodynamics perspective.Design/methodology/approachThe study applies inductive multiple case study of embedded 10 cases of corporate acceleration, covering both incumbent and startup perspectives, occurring in the context of a corporate accelerator.FindingsWe find that (1) the process of corporate acceleration involves three phases, each of them is dominated by a different emotional state (hope, anxiety and acceptance), triggering different behavioral responses; (2) as a means to deal with negative emotions, entrepreneurs and corporate acceleration program's team members develop different mechanisms of dealing with contradictories in subsequent acceleration phases (defense and copying mechanisms), which are reflected in their behaviors. Coping mechanisms with goal reformulation (i.e. refocus from the officially declared “open innovation” goals toward mainly symbolic ones) is an effective strategy to manage negative emotions in third phase of the acceleration.Research limitations/implicationsOur sample is limited to two relatively similar accelerators established by telecom companies, and therefore, our theoretical and practical conclusions cannot be generalized.Practical implicationsWe supplement the studies of corporate accelerators that imply how to design them better and improve decision-making rules with recommendation that in order to improve their effectiveness in terms of learning and innovations, their managers need not only to learn how to manage structural and procedural differences but also how to overcome social defenses triggered by corporate–startups cooperation.Originality/valueBy documenting a multidimensional impact of acceleration process, and especially shedding light on psychodynamic aspects behind such liaisons, this paper contributes to richer understanding of corporate–startup relationships, typically examined through a rationalistic lens of strategy literature. The study contributes to interorganizational research and open innovation literature, by showing that corporate acceleration process is marked by phases based on the type of emotions intertwined with the nature and dynamism of its life cycle. It indicates how these emotions are managed depending on their type.

AbstractThe paper discusses the electroreduction of Bi(III) ions in the aspect of expanding the “cap-pair” effect.The “cap-pair” rule is associated with the acceleration of the electrode’s processes by organic substances. The interpretation of the “cap-pair” effect mechanism was expanded to include the effect of supporting electrolyte concentration on the acceleration process and the type of electrochemical active as well as used protonated organic substances. It has also been shown that the phenomena occurring at the electrode/solution interface can influence a change in the dynamics of the electrode’s process according to the “cap-pair” rule.

The People

The powertrain is a very important subassembly in a car and is responsible not only for the automotive industry’s impact on the environment but also for the safety of people travelling by car and performing overtaking manoeuvres and joining traffic. In general, the powertrain is a combination of the drive unit and drive transmission, wherein the drive unit is responsible for the available driving force in the car’s wheels and for the car’s ability to accelerate when the throttle pedal is rapidly pressed at a constant gearbox ratio. The availability of the driving force reserve in the powertrain is the most important issue for the reason of safety of the people travelling by car. In the case of drive unit what they are of the combustion engines, the rapid pressing of the throttle pedal in the car acceleration process leads to a temporary deficiency in the driving force and in the powertrain’s output. The deficiency in the driving force has a negative impact on acceleration and driving comfort. In this paper, the authors assessed and analysed two different short-term compressed air supercharging systems for combustion engines with air supplied from a high-pressure tank. The analysis covered the response of the combustion engine with spark ignition to the gradual increase in pressure in the air-intake system. The assumption is that the applied short-term compressed air supercharging system could improve the driving force during the phase of the engine’s increasing crankshaft rotational speed. This helps to achieve the improved passenger car acceleration dynamics, depending on the supercharging method and throttle pedal exertion. When analysing the car’s acceleration dynamics, expressed by the shorter time of increasing the longitudinal speed from initial to final, it was possible to shorten the acceleration time. It is also possible to observe an improved driving force behaviour, especially during the first phase of acceleration.

The work purpose is to present history of anthropological study of physical development of the Belarusian children, teenagers and youth. This story originates at the end of the 19th century, at that time the anthropological science endured the period of the formation. In 1920 one of national objectives was health protection of younger generation; systematic study of physical development of the children’s population of BSSR began to be carried out. In the same time uniform methodical approaches were developed, mathematical data processing was introduced. Standards of physical development of the Belarusian children were for the first time created. In 1950 mass researches of health and physical status of children and teenagers in our republic were conducted by forces of doctors and hygienists. Results of their work allowed to establish dynamics and to reveal the main regularities of formation of a children’s organism. New age and sex standards of physical development of school children were created. Since 1970, the staff of department of anthropology of Institute of history NAN of Belarus conducts systematic complex researches of physical development of children, teenagers and youth. Researches include studying of intra group distinctions taking into account growth rates and definition like somatic development. Researches include studying of intra group distinctions taking into account growth rates and definition like somatic development. Thanks to this work in our republic the results illustrating the most important epoch-making regularities of physical development of newborns, preschool children, pupils of schools including acceleration process were received. In historical aspect the most important direction of anthropological researchers at the present stage is monitoring of physical development of the children’s population of Republic of Belarus. Reduction of massiveness of a skeleton was observed in consequence of which a thinner constitution of modern children at the age of 7–17 years is noticed.

Objective: Conflicts have negative impacts on organizational performance and can lead to company mortality. The GVentures Accelerator, from the School of Business Administration of São Paulo (EAESP-FGV) identified that several startups that failed during and after the acceleration process had conflicts among the founding partners. This work aims to understand why some entrepreneurial teams in a pre-seed stage are able to overcome conflicts while others are not Methodology: We conducted a case study of 9 accelerated startups using in-depth interviews with 20 founding partners, and the interviews were followed by the codification and analysis of the cases with support from the manager responsible for the accelerator.Results: The research concludes that operational conflicts that escalate to affective conflicts due to disagreements in the process of giving and receiving feedback and/or mistrust between partners can lead to the dissolution of a company. On the other hand, founding members, even if they experience affective conflicts, are able to overcome the problems using the strategies of taking a step aside, giving in and putting their egos aside. It was also identified that the acceleration process tends to exacerbate the operational conflicts between founding partners.Theoretical/methodological contributions: The research contributes to the literature about founding teams by pointing out that operational conflict does not necessarily lead to the dissolution of the organization or closing the business, but operational conflicts that intensify to affective conflicts due to disagreements in the process of giving and receiving feedback and/or distrust among partners can lead to the dissolution of the organizationRelevance/originality: Founding teams are the backbone of any company. In spite of several articles discussing team conflict little is known about why some entrepreneurial team are able to overcome conflicts while other not. Moreover, also little is known about the role accelerators play in these conflicts.Social/management contribution: The conclusions about the strategies for managing founding team conflicts: taking a step aside, giving in and putting their egos aside; may be very useful for both entrepreneurs and accelerators’ management team in dealing with conflicts among founders.

<p>Acceleration of energetic particles is a fundamental and ubiquitous mechanism in space and astrophysical plasmas. One of the open questions is the role of the sheath region behind the shock in the acceleration process. We analyze observations by Solar Orbiter, BepiColombo and the L1 spacecraft to explore the structure of a coronal mass ejection (CME)-driven sheath and its relation to enhancements of energetic ions that occurred on April 19-20, 2020. Our detailed analysis of the magnetic field, plasma and particle observations show that the enhancements were related to the Heliospheric Current Sheet crossings related to the reconnecting current sheets in the vicinity of the shock and a mini flux rope that was compressed at the leading edge of the CME ejecta. This study highlights the importance of smaller-scale sheath structures for the energization process. These structures likely formed already closer to the Sun and were swept and compressed from the upstream wind past the shock into the sheath. The upcoming observations by the recent missions (Solar Orbiter, Parker Solar Probe and BepiColombo) provide an excellent opportunity to explore further their role.  </p>

AbstractTest particle orbits in the two-dimensional Fadeev equilibrium with a perpendicular electric field added are analyzed to show that impulsive bursty reconnection, which has been proposed as a model for fragmentary energy release in solar flares, may account also for particle acceleration to (near) relativistic energies within a fraction of a second. The convective electric field connected with magnetic island dynamics can play an important role in the acceleration process.Subject headings: acceleration of particles — MHD — plasmas — Sun: corona — Sun: flares
