The attempt to establish a common European framework for core platforms' duties and responsibilities toward other actors in the digital environment is at the core of the recent scholarly debate surrounding the Digital Markets Act (DMA) proposal. In particular, the everlasting juxtaposition between the “data power” – as emerging from recent cases (Section 2) – that dominant tech companies enjoy and the concept of consumer sovereignty (Section 3) lies at the core of the proposal's attempt to identify digital core platforms as market gatekeepers. Accordingly, this chapter critically investigates the divide between power imbalance and consumer sovereignty in light of the architecture designed by the DMA, with a specific focus on its effectiveness in identifying gatekeepers' power drivers (Section 4). After highlighting the main critical aspects of the pertinent rules, opportunities for fruitful developments are then identified through the reframing of some of the notions considered in the proposal, and namely the role of “lock-in” effects and “data accumulation” (Section 5). Lastly, this chapter suggests that the DMA advancements – while desirable – are bound to be fragmentary in the absence of a wider appraisal of the nature of data power imbalance dynamics in the modern digital markets (Section 6).

Throughout an aircraft development process, the conceptual design phase is an extremely important milestone; hence, the quality and success of this step directly affect the overall cost and lead time of the project. Because of this fact, the purpose of this study is to provide outputs and suggestions to the designing engineer regarding the requirements for reducing overall design time as well as costs and creating an ideal design at the early phases of the project by optimizing the aircraft development process.

The system has been prepared parametrically and presents some performance specifications for the aircraft in the early phases of the design, for example, coefficients for lift C_L as well as drag C_D and weight as well as fuel estimations. The software uses a combination of well-known design techniques within just one platform in contrast to many other applications. Because of this feature, it is not needed to use different sub-platforms which would require an appropriate environment and even though would lead to complications with regard to the connectivity. The system also presents relevant information about the aircraft performance like velocity versus load factor (V-n) diagrams, maximum turn rate of climb, turn rate and climb angle graphs in contrast to many other open-source conceptual design platforms.

In this study, authentic General Dynamics F-16 Fighting Falcon and McDonnell Douglas F-15 Eagle data were used as input to the system, and advanced geometric and/or performance graphs were obtained and compared to the literature where a good agreement of the results was observed. These results with regard to the aircraft performance are typically product specific and quite rare in the literature. These data obtained by use of the software during the aircraft design are, thus, of major interest, especially for the design of new aerospace platforms. In this study, all of these graphs (especially the remarkable V-n diagram) are obtained on one platform.

The aircraft conceptual design and analysis system software provides information and suggestions regarding the requirements for reducing the overall design time, reducing the design costs and creating an optimized design at the early phases of a project by optimizing the aircraft development process within just one convenient, that is, user friendly, platform, where it uses a combination of varying methodologies. Besides presenting one interface, which is quite typical for conceptual design tools, it allows applications of methods like vortex lattices and finite differences for obtaining aerodynamic performance parameters.

The purpuse of this study is to answer the following two questions. Do conflict management efforts mitigate the recurrence and severity of civil conflict? If so, how? Do some conflict management strategies fare better than others in these tasks? This study theorizes about the connection between the costliness of a conflict management strategy – with respect to both the disputants and third parties – and civil conflict outcomes. This theory produces two contradictory predictions: that more costly strategies either increase or decrease violence. This study not only adjudicates between these two possibilities but also incorporates the role of timing. The early use of more costly strategies, for example, may encourage disputants to reduce violence in civil conflicts.

To evaluate the predications that the authors derive from their theoretical argument, the authors quantitatively analyze the effect of conflict management strategies’ relative cost on various measures of civil conflict recurrence and severity. The authors first identify the set of international–civil militarized conflicts (I-CMCs) during the period 1946–2010. I-CMCs contain two dimensions – interstate and intrastate – making them the most complex and dangerous form of militarized conflict. To each I-CMC, the authors then link all third-party attempts to manage the I-CMC’s civil conflict dimension. Finally, after developing quantitative indicators, a series of regression equations explore the relationships of primary interest.

Two main findings emerge. First, when third parties use a relatively more costly conflict management strategy to manage a civil conflict (e.g. a peace operation or military intervention, as opposed to mediation), the severity of the conflict increases, while conflict recurrence rates remain unchanged. Second, this study uncovers a trade-off. The early use of a relatively more costly management strategy lowers a civil conflict’s severity in the short-term. It also, however, increases the likelihood – and speed with which – civil conflict recurs. The timing of certain conflict management strategies matters.

Scholars typically isolate conflict management strategies in number (i.e. consider efforts as independent of one another, even those within the same conflict) and kind (i.e. examine mediation but not peace operations). This study, in contrast, includes the following: the full menu of conflict management strategies available to third parties – negotiation, mediation, adjudication/arbitration, peace operations, sanctions and military intervention – over a lengthy time period (1946–2010); theorizes about the relative merits of these strategies; and considers the timing of certain conflict management efforts. In so doing, it highlights a policy trade-off and proposes promising areas for future research.

During COVID-19, this study aims to evaluate the crisis communication strategies (CCS) of Fortune 500 medical device businesses. These companies’ CCS adoption is evaluated using data from the microblogging site Twitter.

A total of 11,569 tweets were collected over the course of a year, from 31 December 2019 to 31 December 2020, and analysed using COVID-19’s pre-crisis, crisis and new normal stages. The data acquired from Twitter is assessed using latent Dirichlet allocation-based topic modelling, valence aware dictionary for sentiment reasoning sentiment analysis and emotion recognition analysis and then further examined using fuzzy set qualitative comparative analysis to build a configurational model. The findings were compared to Cheng’s (2018, 2020) integrated strategy toolkit for organisational CCS, which included 28 strategies.

With positive sentiments across stages, companies chose “information providing”, “monitoring” and “good intentions” as the CCS. In the crisis and new normal stages of COVID, the emotion of “depression” was observed.

Researchers would be able to assess the CCS used through visual aids in the future by conducting a cross-industry examination using image analytics. Furthermore, by prolonging the study’s duration, long-term changes in the CCS can be investigated.

Companies should send real-time information to their stakeholders via social media during a pandemic, conveying good intentions and positive sentiments while remaining neutral.

To the best of the authors’ knowledge, this is one of the first studies to investigate the CCS patterns used by medical device businesses to communicate via social media during a pandemic.
