Musical Viruses for graceful seduction

The +++ Wearable Player is a result of the application of the Rights through Making approach in designing wearables. This approach aims at designing systems, whose use empowers people towards the materialization of values (e.g. human rights). The +++ Wearable Player system elaborates on the previous project Sound Experience, and introduces the concept of viral music exchange as a motivating factor in the context of social health. This paper describes the morphological genesis, the functional aspects and how they have been implemented in a fully working experienceable prototype. The design process and its outcomes are illustrated, in the framework of the “changing behaviour” design trend

Fear: A Misunderstood Component of Organizational Transformation

Corporate transformations are being implemented by many organizations, however, successes are remarkably rare. This paper suggests that a contributing factor might be the ineffective use of fear in employee communications. Rather than reducing fear, companies can enhance the transformation process by harnessing fear to quickly change behavior. Protection motivation theory has been applied by marketing researchers to suggest that fear appeals containing strong threats and information on coping strategies can be successful in changing behavior. Human resource managers can be instrumental in designing effective communications that incorporate fear-inducing messages and information on coping strategies

How calibration committees can mitigate performance evaluation bias: An analysis of implicit incentives

While prior research on performance evaluation bias has mainly focused on the determinants and consequences of rating errors, we investigate how a firm can provide implicit incentives to supervisors to mitigate these errors via its calibration committee. We empirically examine the extent to which a calibration committee incorporates supervisors' evaluation behavior with respect to their subordinates in the performance evaluation outcomes, i.e., performance ratings and promotion decisions, for these supervisors. In our study, we distinguish between lack of skills and opportunism as two important facets of evaluation behavior, which we expect the calibration committee to address differently. Using panel data of a professional service firm, we show that supervisors' opportunistic behavior to strategically inflate subordinates' performance ratings is disciplined through a decrease in the supervisors' own performance rating, while the supervisors' skills to provide less compressed and thus more informative performance ratings is rewarded through a higher likelihood of promotion.Series: Department of Strategy and Innovation Working Paper Serie

The Efficiency Cost of the Kafala in Dubai: A Stochastic Frontier Analysis

The Kafala (or sponsorship) system is the key instrument behind the economic development of the United Arab Emirates (UAE) and most Middle East economies. The system governs both labor migration and foreign investment by assigning a native-UAE sponsor to each migrant worker and each foreign investor. Sponsors enjoy significant command over these factors and extract sizable economic rents. Firms in free-zones, in contrast, are exempt from the Kafala system. Therefore, they provide an appropriate counterfactual to study the effect of policy regulations on technical efficiency. Using a representative sample of 600 firms of Dubai we estimate stochastic frontier models to identify and compare the degree of technical inefficiency between firms operating under the Kafala system and those in free zones. Our results suggest that on average technical inefficiency resulting from the Kafala amounts to 6.6% of total costs (or 11% of profits). Inefficiency is also greater among firms in Main Dubai in all economic sectors.Labor sponsorship (Kafala), technical inefficiency, economic rents

The Self-Selection in the Migration Process: What Can We Learn?

This paper reviews the theoretical and the empirical literature regarding migration in order to cast some light upon the nature of self-selection. In particular it attempts to identify the specific factors which induce a skilled rather than an un-skilled migration. As a result, some conclusions upon the existence as well as the determinants of selective processes in migration will be offered. Three contributions of the theoretical literature can be highlighted: first, sending country characteristics vis-à-vis host country conditions create uneven incentives for different levels of abilities or education, and therefore create the ground for a selectivity process. Second, migration costs play a major role in determining the direction of the selectivity and third, host country migration policies as well as demand side considerations influence the direction of the selection. The empirical evidence shows that the direction of the selectivity in terms of educational level varies considerably across countries: in some cases the emigrant flow is mainly characterized by highly educated individuals, whereas in other, the emigration flow is predominantly made by low skilled individuals. On the contrary in terms of unobservable characteristics, the empirical literature reveals that either the movers are positively selected or they are not selected at all.

Can hyper-synchrony in meditation lead to seizures? Similarities in meditative and epileptic brain states

Meditation is used worldwide by millions of people for relaxation and stress relief. Given sufficient practice, meditators may also experience a variety of altered states of consciousness. These states can lead to a variety of unusual experiences, including physical, emotional and psychic disturbances. This paper highlights the correspondences between brain states associated with these experiences and the symptoms and neurophysiology of epileptic simple partial seizures. Seizures, like meditation practice, can result in both positive and negative experiences. The neurophysiology and chemistry underlying simple partial seizures are characterised by a high degree of excitability and high levels of neuronal synchrony in gamma-band brain activity. Following a survey of the literature that shows that meditation practice is also linked to high power gamma activity, an account of how meditation could cause such activity is provided. This paper discusses the diagnostic challenges for the claim that meditation practices lead to brain states similar to those found in epileptic seizures, and seeks to develop our understanding of the range of pathological and non-pathological states that result from a hyper-excited and hyper-synchronous brain

Models to detect scientific creativity: Why something simpler than Fréchet Metric Manifolds?

We claim that the models needed to describe scientific creativity (and, in particular, suitable to effectively detect it) have to be very sophisticated. Indeed, the process of creating original and predictive scientific theories is manifestly the most complex ever investigated by the human mind (There are also some paradoxical aspects in the action of a mind that is investigating its own way of functioning, but we are confident that it will be possible to avoid them). In mathematical physics one of the most complex state space structures is given by Frechet Metric Manifolds. We conjecture that they will be needed to model the state of complexity of the mind of a scientist (However, we will not be surprised if an even more complex structure could be needed). The obtained models have a very important application: they are essential to design and rule the selection process that assigns a university chair (or a research grant). Recently some algorithms have been introduced to calculate some bibliometric indices. We claim that it is not reasonable to use them to evaluate the scientific quality of researchers, chair or grant holders, departments or whole universities. Instead, the only presently viable process must involve carefully designed procedures, similar to those used for forming juries. These procedures must be enforced to rule the formation and functioning of ad hoc peer committees entrusted to evaluate academic institutions and nominate professors, chairs or research grant holders. Bibliometrics and Scientometrics are too young as disciplines and therefore it is not possible yet, by means of the theoretical insight gained thanks to them, to design a more effective evaluation process. Only when game and artificial intelligence theories become sufficiently advanced will it become possible to efficiently replace selection peers committees (i.e. academic juries)
