The article deals with necessity as one of the circumstances precluding wrongfulness under customary international law and how it will likely gain relevance in view of the difficulty to quickly attribute malicious cyber operations that threaten important assets of a state. While the necessity doctrine seems fit for purpose, it lacks granularity and is problematic from an international rule-of-law point of view. Taking these pitfalls into account, the article proposes some general principles for a possible special emergency regime for cyberspace.

Teams performing scientific research are becoming increasingly large and interdisciplinary. While prior work has examined antecedents and performance implications of these trends, it is not clear how team size and interdisciplinarity relate to teams’ internal organization, especially the division of labor (DoL) between members. We first develop an organizing framework that integrates three complementary dimensions of DoL: (1) the specialization of individual team members, (2) the distribution of activities across team members, and (3) interdependencies between activities. We then discuss how these aspects of DoL are related to team size and interdisciplinarity and test our hypotheses using author contribution data from over 12,000 scientific articles. We find that team size has a positive relationship with an aggregate measure of DoL, but disaggregated measures show that this relationship holds for some aspects of DoL and not others. We also find that interdisciplinary teams use greater division of labor, although this effect depends on the degree to which interdisciplinarity is intra- versus inter-personal. We conclude by discussing how our conceptual and empirical toolkit may be applied in future research on the drivers and consequences of division of labor in teams.

With the onset of the 2020 coronavirus pandemic, industrial suppliers are increasingly challenged to close their open sales opportunities and keep generating business. Against this backdrop, the authors of this study investigate which offerings industrial customers are most likely to purchase as the pandemic progresses. Drawing on positive decision theory and empirically investigating 31,353 sales opportunities across 57 countries, the authors show that the coronavirus pandemic significantly decreases industrial customers' purchase probability, especially for high-priced offerings. In countries with low uncertainty avoidance and strong long-term orientation (e.g., China, India, Singapore), purchase probability is less affected by the pandemic. The coronavirus pandemic even increases purchase probability for offerings with low prices in countries where cultures are simultaneously uncertainty-avoidant and short-term oriented (e.g., Argentina, Brazil, Mexico). This is presumably because customers safeguard their operations in the face of impending supply shortages. Consequently, this helps suppliers focus on the right sales opportunities to secure their business during exogenous global shocks such as the coronavirus pandemic.

Following the turn to practice in organization theory and the emerging interest in the microfoundations of ambidexterity, understanding the role of individuals in realizing ambidexterity approaches becomes crucial. Drawing insights from Greek philosophy on paradoxes, and practice theory on paradoxes and ambidexterity, we propose a view of individual ambidexterity grounded in paradoxical practices. Existing conceptualizations of ambidexterity are largely based on separation strategies. Contrary to this perspective, we argue that individual ambidexterity can be accomplished via paradoxical practices that renegotiate or transcend boundaries of exploration and exploitation. We identify three such paradoxical practices at the individual level that can advance understanding of ambidexterity: engaging in “hybrid tasks,” capitalizing cumulatively on previous learning, and adopting a mindset of seeking synergies between the competing demands of exploration and exploitation.

Citizen Science (CS) projects involve members of the general public as active participants in research. While some advocates hope that CS can increase scientific knowledge production (“productivity view”), others emphasize that it may bridge a perceived gap between science and the broader society (“democratization view”). We discuss how an integration of both views can allow Citizen Science to support complex sustainability transitions in areas such as renewable energy, public health, or environmental conservation. We first identify three pathways through which such impacts can occur: (1) Problem identification and agenda setting; (2) Resource mobilization; and (3) Facilitating socio-technical co-evolution. To realize this potential, however, CS needs to address important challenges that emerge especially in the context of sustainability transitions: Increasing the diversity, level, and intensity of participation; addressing the social as well as technical nature of sustainability problems; and reducing tensions between CS and the traditional institution of academic science. Grounded in a review of academic literature and policy reports as well as a broad range of case examples, this article contributes to scholarship on science, innovation, and sustainability transitions. We also offer insights for actors involved in initiating or institutionalizing Citizen Science efforts, including project organizers, funding agencies, and policy makers.

The article examines the legal qualification of state-led information operations that aim to undermine democratic decision-making processes in other states. After a survey of the legal attitudes of states towards such operations during the Cold War, the impact of the digital transformation on the frequency and quality of information operations is explained. The article then assesses scholarly responses to the outlined paradigm shift regarding the prohibition of intervention, respect for sovereignty and the principle of self-determination. The study then inquires whether it is possible to detect a change in how states qualify adversarial information operations by tracking recent state practice and official statements of opinio juris. The survey concludes that there is insufficient uniformity to allow for an inference that the content of the analysed rules of customary international law has already shifted towards more restrictive treatment of foreign interference. As a possible way forward, the article ends with a proposal to focus on deceptive and manipulative conduct of information operations as the most viable path to outlaw such state behavior in the future. Instead of attempting to regulate the content of information, this approach is better suited to safeguard freedom of speech and other potentially affected civil rights.

In distributive negotiations, people often feel that they have to choose between maximizing their economic outcomes (claiming more value) or improving their relational outcomes (having a satisfied opponent). The present research proposes a conversational strategy that can help negotiators achieve both. Specifically, we show that using an offer framing strategy that shifts offer recipients' attention to their reservation price (e.g., “How does my offer compare to your minimum price?”) leads to both (a) an assimilation effect whereby recipients make more favorable counteroffers (economic benefit) as well as (b) a contrast effect whereby recipients feel more satisfied with the negotiation (relational benefit). We find evidence for the effectiveness of this conversational strategy across four experiments (N = 1522) involving different negotiation contexts (real estate, restaurant sale) and participant samples (MBAs, sales agents, online participants), and also document negotiator power as an important boundary condition. Overall, our research suggests that economic and relational benefits do not have to be mutually exclusive in distributive negotiations, that the perceived extremity of an offer is subjective and can be strategically influenced, and that assimilation and contrast effects can operate simultaneously when they relate to separate outcomes.

Increasing dependence on information technology calls for strengthening the requirements on their safety and security. Vulnerabilities that result from flaws in hardware and software are a core problem which market mechanisms have failed to eliminate. A strategy for resolving this issue should consider the following options: (1) private- and public-sector
funding for open and secure production, (2) strengthening the sovereign control over the production of critical IT components within an
economic zone, and (3) improving and enforcing regulation. This paper
analyses the strengths and weaknesses of these options and proposes
a globally distributed, secure supply chain based on open and mathematically proved components. The approach supports the integration
of legacy and new proprietary components.
