British Educational Research Journal, EarlyView.Abstract As front‐line observers and active participants in pupils' daily lives, teachers closely monitor pupils' social interactions, emotional states and behavioural changes. Their unique perspective enables them to detect problems in the social lives of their pupils that may not be immediately visible to peers, parents or mental health professionals.

A practical bistatic passive radar system for use with DAB and DRM illuminators [PDF]
, 2008 Digital broadcasts provide powerful illuminators of opportunity with waveforms that produce excellent radar ambiguity functions. An experimental program to investigate the possibility of such broadcasts for target tracking radar is described. In addition,

Business Strategy and the Environment, EarlyView.ABSTRACT Global net‐zero ambitions require transformative strategies to decarbonise carbon‐intensive global value chains (GVCs). This study examines how multinational enterprises (MNEs) in sunset industries integrate carbon capture technologies (CCT) with operational and supply chain dynamics (OSCD) to advance decarbonisation.

Cross-ambiguity Function Shaping Through Fractional Quadratic Programming
Leida xuebaoDue to the mismatch between transmit waveforms and receive filters, Cross-Ambiguity Function (CAF) shaping plays an important role in the design of cognitive radar waveforms and allows more freedom for waveform optimization problem than conventional ...

Leading the Loop: Anchor‐Led Orchestration in Nascent Circular Ecosystems—A Qualitative Case Study
Business Strategy and the Environment, EarlyView.ABSTRACT The transition towards a circular economy necessitates coordinated, systemic change across value chains. Yet the role of anchor firms in initiating and orchestrating nascent circular ecosystems remains underexplored. Using an inductive, qualitative single‐case design, we analyse a German mid‐sized entrepreneurial firm, drawing on 21 interviews

Connecting Thoughts and Actions: A Managerial Process Model on Circular Business Model Innovation
Business Strategy and the Environment, EarlyView.ABSTRACT Addressing environmental grand challenges such as resource scarcity requires circular business model innovation (CBMI) that enables firms to efficiently close and slow resource cycles through novel activity systems. Drawing on a grounded theory approach based on 59 in‐depth interviews with top managers from Swiss SMEs, we developed a process ...

Radar matched filtering using the fractional fourier transform [PDF]
, 2010 -A matched filter is the optimal linear filter for maximizing the signal to noise ratio (SNR) in the presence of additive noise. Matched filters are commonly used in radar systems where the transmitted signal is known and may be used as a replica to be ...
