We study the case of Vietnam to assess the long-lasting role of institutional and historical legacy on entrepreneurial outcomes. In particular, we investigate the detrimental effect of socialist institutions on entrepreneurship. Vietnam offers a unique quasi-experimental setting because the country was divided into the socialist North and the nonsocialist South for a relatively short period of two decades. After reunification, the South adopted the institutional framework conditions of the North. To assess the relationship between socialist history and entrepreneurship in this unique setting, we survey more than 3,000 North and South Vietnamese individuals more than four decades after the reunification of the country. We find that North Vietnamese respondents have lower entrepreneurship intentions, are less likely to select into entrepreneurship education programs, and are less willing to engage in a business takeover. These patterns indicate the persistence of historical differences in institutional framework conditions on entrepreneurship. We conclude by outlining the implications of a socialist legacy for entrepreneurship theory and policymakers. [less ▲]

Linear precoding boosts the spectral efficiency of the satellite system by mitigating the interference signal. Typically, all users are precoded and share the same bandwidth regardless of the user demand. This bandwidth utilization is not efficient since the user demand permanently varies. Hence, demand-aware bandwidth allocation with linear precoding is promising. In this paper, we exploited the synergy of linear precoding and flexible bandwidth allocation for geostationary (GEO) high throughput satellite systems. We formulate an optimization problem with the goal to satisfy the demand by taking into account that multiple precoded user groups can share the different bandwidth chunks. Hence, optimal beam groups are selected with minimum bandwidth requirement to match the per beam demand. The simulation results show that the proposed method of combining bandwidth allocation and linear precoding has better bandwidth efficiency and demand satisfaction than benchmark schemes. [less ▲]

Active nanophotonics can be realized by controlling the optical properties of materials with external magnetic fields. Here, we explore the influence of optical anisotropy on the magneto-optical activity in non-magnetic hyperbolic nanoparticles. We demonstrate that the magneto-optical response is driven by fundamental electric and magnetic dipole modes induced by the hyperbolic dispersion. Magnetic circular dichroism experiments confirm the theoretical predictions and reveal tunable magneto-optical activity across the visible and near infrared spectral range. [less ▲]

In recent years cross-border vocational educational training (VET) in cross-border regions has gained more and more importance. The overall research question is how regional learning processes are shaped by bilateral cross-border formal learning agreements in a border region. Therefore, we build our own model of regional learning in border regions on WELLBROCK et al. (2012) following an integrated conceptual perspective and focusing on the actor’s perspective. The development of this transboundary VET by a variety of actors can be considered to form an intra- und interregional learning process. The interpretation of the structures regarding the conceptual findings reveals that the learning processes in the Saarland-Lorraine border region are dynamic and depend on key actors with expert knowledge as well as advantageous regional characteristics.

Executive bodies can acquire constitutive powers,even if subject to detailed substantive strictures. Constitutive powers give executive bodies the possibility to transform normative understandings of the meaning of norms and of the goals of public action into legal forms. These bodies thus engage in a jurisgenerative process that enables them to progressively delimit their legal mandates in reaction to socio-economic and political realities. The article illustrates this argument by examining the power of the EU Single Resolution Board (SRB) to determine the resolution of a bank in crisis. It concludes that, in view of constitutive powers, the normative demands that the EU legal system places on executive and administrative bodies must be reconsidered. On that basis and to that effect, mechanisms of accountability should be reconceptualised and reoriented. [less ▲]

Unsteady and pulsatile flows receive increasing attention due to their potential to enhance various microscale processes. Further, they possess significant relevance for microfluidic studies under physiological flow conditions. However, generating a precise time-dependent flow field with commercial, pneumatically operated pressure controllers remains challenging and can lead to significant deviations from the desired waveform. In this study, we present a method to correct such deviations and thus optimize pulsatile flows in microfluidic experiments using two commercial pressure pumps. Therefore, we first analyze the linear response of the systems to a sinusoidal pressure input, which allows us to predict the time-dependent pressure output for arbitrary pulsatile input signals. Second, we explain how to derive an adapted input signal, which significantly reduces deviations between the desired and actual output pressure signals of various waveforms. We demonstrate that this adapted pressure input leads to an enhancement of the time-dependent flow of red blood cells in microchannels. The presented method does not rely on any hardware modifications and can be easily implemented in standard pressure-driven microfluidic setups to generate accurate pulsatile flows with arbitrary waveforms.

Since 2018, deep fakes technology has been one of the areas in which artificial intelligence has evolved dramatically and thus, deep fakes are primarily seen by governments as an emerging threat. In particular, regulators are increasingly concerned by the developments and applications of this technology in two main areas: image-based sexual abuse and disinformation. Despite its increasing popularity, there are challenges in defining what deep fakes are and what ought to be regulated when it comes to deep fake phenomena. The following article aims to analyze the EU-level regulatory approach to deep fakes in relation to AI regulation. This choice is motivated by the inclusion of deep fakes in the proposed EU Artificial Intelligence Act and the nature of the provisions that apply to deep fake technology within the Act. The first part will analyze the issues and challenges of adopting a legal definition for deep fakes to highlight consensus and differences among scholars and industry players. Getting the scope of the definition right is essential to address appropriately the distinct harm profile stemming from deep fake technology, specifically in relation to image-based sexual abuse and disinformation. A survey of different views shows a consensus over two elements that define deep fakes: the use of AI-based technology and the intent of the creator. However, there are practical challenges to this seemingly consensual definition, particularly when it comes to drawing boundaries between deep fakes and lower AV manipulation (i.e.: cheap fakes) and to co-opting the term to discredit audiovisual content, and casting doubts on the veracity of AV content presented as evidence. The second part focuses on the transparency requirements for deep fakes under the proposed EU Artificial Intelligence Act proposal. This obligation will be examined in light of disclosure and labelling obligations already tested in disinformation strategies, particularly in the implementation of the EU Code of Practice on Disinformation 2018, which will likely include deep fakes in its new iteration to be published in spring 2022. Among the main lessons from the application of the Code of Practice on Disinformation, it is clear that labels alone are not an effective measure to counter disinformation or deter its creation and dissemination. Moreover, if users are to rely on labels to weigh whether they are interacting with manipulated media, more research is needed into effective design since newer forms of enhancing transparency are available but not necessarily implemented by companies. This is particularly relevant in the context of the proposed Artificial Intelligence Act, since scholars have serious concerns of its enforcement architecture. Finally, the third part of this article illustrates a brief comparative approach between the United States and the United Kingdom regulatory responses to deep fakes to assess further the current EU response to this phenomenon. In contrast to the EU response, which so far is based on minimal transparency requirements, other jurisdictions' trend has been primarily to criminalize the malicious use of deep fakes which is often assimilated to revenge pornography even though these are two different phenomena. For all of these reasons, deep fakes are at the intersection of different possible regulatory frameworks providing an interesting case to explore the regulatory challenges of AI in the context of the European Union.
