Prejudice and emotional sensemaking in post-acquisition integration: a case study of Chinese acquisitions in the UK
No full textMany mergers and acquisitions (M&As) fail, and an emerging body of literature highlights the role of prejudice in derailing the M&A process. While prejudice is frequently observed in M&As, strategies to mitigate these biases remain underexplored. Adopting a qualitative case study approach, this study focuses on Chinese acquisitions in the UK and examines how managers from both the acquired and acquiring organizations navigate prejudice through emotional sensemaking. The findings demonstrate that emotional sensemaking plays a critical role in shaping the post-acquisition integration (PAI) process and its outcomes. Specifically, sensemaking supported by emotional intelligence facilitates the accommodation or reduction of prejudice, while emotionally unintelligent sensemaking tends to reinforce it. By focusing on the dynamic, interactive emotional exchanges between managers at the micro level, this study offers a fresh lens on the integration process beyond traditional strategic or structural explanations. The study contributes to the literature by advancing the understanding of micro-level emotional sensemaking in PAI, emphasizing the dynamic, interactive nature of emotional sensemaking between acquirer and acquiree managers, and its impact on the integration process and outcomes
Spectral efficiency maximization in pinching-antenna-enabled CR networks
No full textIn this paper, we investigate a cognitive radio (CR)network underpinned by pinching antennas (PAs), in which both the primary transmitter (PT) and secondary transmitter(ST) employ a single waveguide and multiple PAs to supports simultaneous spectrum sharing. A sum spectral efficiency (SE)maximization problem is formulated to jointly optimize the pinching beamforming at both the PT and ST, under constraints on the PA deployment. To solve this non-convex problem, a two stage optimization algorithm is developed, which sequentially optimizes the PT and ST pinching beamforming. For each pinching beamforming optimization, the coarse positions of the PAs are first determined at the waveguide level, followed by wavelength-level refinements to achieve constructive signal combining at the target user and destructive superposition at the non-intended users. Simulation results demonstrate that PAs yield substantial SE gains compared to conventional fixed position antennas
Channel measurements for indoor and outdoor reconfigurable intelligent surface (RIS)-assisted links at 3.5 GHz
No full textThis paper explores a far-field RIS-assisted communication environment operating at 3.5 GHz. A comprehensive channel measurement campaign is conducted in both indoor and outdoor settings, covering scenarios with the RIS activated and deactivated, using both directional and omnidirectional antenna configurations. The results show that activating the RIS flattens the channel response and reduces frequency selectivity in both indoor and outdoor environments. Additionally, with directional antennas, the received power levels are a few dB higher in both the RIS-on and RIS-off cases compared to using omnidirectional receive antennas.<br/
"‘you new worlds may justly make’: Youth, Imagination and World-Building During the English Civil Wars"
No full textThis essay explores girlhood imagination in the context of war through an analysis of Jane Cavendish (1621-1669) and Elizabeth Brackley’s (1626-1663) juvenilia. Bringing together the fields of the history of childhood, girlhood studies, early modern women’s writing, and children and young people in sites of conflict and peacebuilding, it offers a new reading of the sisters’ highly self-conscious writing in England during the seventeenth-century civil wars and argues for the significance of historical girl-authored literature to understanding the experiences of young people at times of conflict. It proposes that their writing constitutes a distinctly aged and gendered response that exemplifies the role that creativity might offer the young to negotiate the material and emotional impacts of war. Arguing that their works represent girlhood behaviour as a paradigm for overcoming some of war’s challenges, it contends that their youthful authorship is an act of creating alternative worlds and community building in the face of crisis
MmWave integrated localization, mapping, and communication: A stochastic geometry perspective
No full textTransmit power minimization in stacked intelligent metasurface-aided multi-user systems
No full textStacked intelligent metasurfaces (SIMs), emerging as a revolutionary programmable electromagnetic architecture,have demonstrated unprecedented capabilities in manipulating wireless propagation environments. However, the existing research on SIM-aided downlink communication does not consider the fairness among users. Therefore, this paper studies a SIM-aided hybrid analog-digital system, which aims to fairly guarantee the communication quality of each user while minimizing the transmission power. The hybrid system avails of a SIM for enhancing the communication channel with digital precoding to effectively suppress the interference between users. To this end,we formulate a transmit power minimization problem under quality-of-service constraints, solved by an efficient alternating optimization (AO) algorithm. Simulation results demonstrate that compared to conventional fully digital multiuser multiple input single-output (MISO) systems, the proposed SIM-aided hybrid system requires 6.93 dBm less transmit power under the same signal-to-interference-plus-noise ratio (SINR) constraints for users. This work reveals the SIM’s powerful wave-based beamforming capabilities, providing effective solutions for energy efficient networks with low hardware cost.<br/
Moving out to come out and feel at home: queer cosmopolitanism in Karim Ainouz’s <i>Futuro Beach</i>
No full textCosmopolitanism captures two entangled dimensions: the envisioning of oneself as part of the world and a moral orientation guided by hospitality. In other words, cosmopolitanism is a mode of world citizenship and a positive way of sharing the world with strangers. In film studies, scholars have embraced cosmopolitan discourses to address issues regarding migration, cross-cultural encounters and why cultural difference is still perceived as threatening in a globalized context. This article contributes to these debates, focusing on queer migration, a theme not yet fully explored by the film literature on cosmopolitanism. It suggests that queer migration has the potential to rearticulate cosmopolitan dynamics of citizenship and hospitality through affective and visceral modes of relating to the stranger and the world. Focusing on Karim Aïnouz’s Futuro Beach (Praia do Futuro, 2014), the article frames cosmopolitan hospitality as responsible for forging a queer space, a home, where libidinal encounters and expressions of queer sexuality can take place. Furthermore, it contends that cosmopolitan hospitality creates conditions for the queer migrant to appropriate the host’s home, erasing power relations, while rearticulating their out-of-placeness through a renewed sense of belonging. The article explores these aspects through an interdisciplinary approach combining philosophy, cultural studies and geography to address film studies’ spatial and affective turn. Through analyzing the enactment of space, narrative, and how queer bodies inhabit the world, this contribution frames hospitality less as an ethico-political cosmopolitan disposition, and more as a mediator of cosmopolitan citizenship characterized by the negotiation of feeling at home.<br/
The research-engaged practitioner: the importance of research literacy and critical reflection for the novice teacher’s professional learning
No full textThis contribution examines the role of Initial Teacher Education (ITE) in preparing novice teachers to embrace their identity as research-engaged practitioners. It argues that professional learning is built upon the cultivation of research literacy and critical self-reflection. The approach aligns with professional standards which place value on engagement with research evidence to develop, evaluate and reflect on practice. The authors discuss how the ITE student experience can be enhanced by flexible and inclusive pedagogy
