Whereas the literature in entrepreneurial financing indicates that investors rely on their gut feelings, it remains unclear which entrepreneur attributes factor into this type of intuitive judgment. This study presents a holistic model of entrepreneur attributes as they relate to inventors’ evaluation of funding potential. The model is divided into three categories: entrepreneur–investor relational attributes, entrepreneur motivational attributes, and venture performance-influence attributes. The model is then tested on real-time pitch competitions, by analysing data from technology start-up entrepreneurs, psychologist evaluators, and investors. The model is grounded in dual-processing theory and signalling theory. It is hypothesised that investors base their evaluations on their intuitive judgment of the entrepreneurs. Entrepreneurs’ competence, coachability, passion, preparedness, and leadership are shown to be associated with investors’ evaluations of funding potential.

Attention is the means by which individuals select and process a limited amount of input from the enormous amount of internal and environmental inputs bombarding the senses, memories and other cognitive processes. This article develops a coherent theory of organizational attention, drawing on Cornelissenșs domain-interactive metaphor model. Topics that form the building blocks of individual attention research, including selective and divided attention, automatic versus controlled processes, attention and memory, attention and learning, are examined in terms of their applicability to the organizational context.

Unfortunately, in this field, there is much that is still unknown. The findings of this study, despite its limitations and its small scope, shed some light on some of the salient differences between WOM in the real world and WOM in a social network. This study indicated that, like WOM in the real world, negative WOM is spread more rapidly and more widely than positive WOM. We also found, not surprisingly, that the greater the identification with the message, the greater the intention to act in compliance with the message. Opinions about the message sender were more positive for negative WOM. These findings match what we know about WOM in the real world. In contrast, we discovered that, unlike the real world, people are likely to spread WOM in a social network even if they do not especially identify with the message. A poss...

We demonstrate that the spatial distribution of the magnetic field leads to a non-monotonic dependence of the coupling coefficient on coil size. Thus, an optimal coil size, where the coupling coefficient peaks, should be regarded a crucial design parameter which affects the entire system performances. The incorporation of our findings into a multi-objective optimization algorithm is also discussed.

Such measures impose a hurtful toll on the economy, and are difficult to sustain for extended periods. The challenge is that selective isolation of the symptomatic patients is insufficient to control SARS-CoV-2, due to its relatively long incubation period, in which individuals experience no symptoms, but may already contribute to the spread. How then do we isolate these \textit{invisible} pre-symptomatic spreaders? Here we propose an alternating quarantine strategy, in which at every instance, half of the population remains under lock-down while the other half continues to be active, maintaining a routine of weekly succession between activity and quarantine. Under this regime, if an individual was exposed during their active week, by the time they complete their quarantine they will, in most cases, begin to exhibit sym...
