The 60-minute minimum viable product (MVP) exercise teaches critical aspects of the entrepreneurial mind-set and lean start-up methodology, namely, the iterative process of hypothesis testing through the creation of MVPs. In 60 minutes, with no prior technical expertise, students will work in teams to design a landing page, create a teaser video, and set up a way to gather information from prospective customers. The resulting low-fidelity MVP can subsequently be shared with prospective customers to gauge interest and be used as a starting point for the hypothesis testing process used in the lean start-up methodology. This is an immersive exercise that activates students, builds confidence, and teaches important entrepreneurial principles.

Este trabajo asume como punto de partida que el escándalo suscitado tras la incautación del llamado archivo Castiglioni -donde se presume existen pruebas de espionaje ilegal en democracia- configuró una ventana de oportunidad que permitió colocar nuevamente los asuntos de inteligencia en la agenda de gobierno. A partir del marco de corrientes múltiples, se argumenta que el ágil reconocimiento del problema, mediante la creación de una comisión investigadora parlamentaria (corriente de los problemas) y la presencia de soluciones concretas aportadas por los poderes ejecutivo y legislativo (corriente de las políticas), suponen una oportunidad de cambio que dependerá, en gran parte, de la capacidad de los actores para capitalizar la misma: reducir la brecha entre soluciones y problemas (corriente de la política).     Abstract This work assumes as a starting point that the scandal that arose after the seizure of the so-called Castiglioni archive -where there is presumption that there is evidence of illegal espionage in democracy- set up a window of opportunity that allowed to put intelligence issues back on the government agenda. From the framework multiple-streams, it is argued that the agile recognition of the problem through the creation of a parliamentary commission of inquiry (problem stream) and the presence of concrete solutions provided by the executive and legislative (policy stream) represent an opportunity for change that will depend largely on the capacity of actors to capitalize on it: bridging the gap between solutions and problems (political stream).

The axes of the creation and birth of the imaginary as a mythical language. Our research follows the relationships of the concepts that are taking into account creation on the double axis of verticality and horizontality. We highlight those symbolic elements which would later constitute the mythical language about the sacred space-temporality. Inside this space-temporality a rich spectrum of mythical images develops; images capable of explaining the relationships of the creation plans. Without a religious perception of the temporality, the conceptualization of the axis would remain a philosophical approach. Through our point of view, the two are born simultaneously. Thanks to them, creation can be imagined. The first “frozen” formula of the mystical human spirit can be thought, brought to a palpable reality, expressed in an oral and then a written form. Studied together, temporality (sacred or not) and space are permanently imagined together. For example, a loss of mundane temporality in the secret ecstasy that offers to the soul an ascending direction does not mean getting out of universal temporality, but of its mundane section. In the sacred space the soul relates to time. Even the gods are submitted by the sacred, Aeon sometimes being synonymous to destiny. The universal creator seems to evade every touch, but not consistently, only when he avoids the descent into its created worlds. In sacredness, time and space seem or become confused, both expressing the same reality, by the immediate swing from thinking to deed. The mythical imagery conceives the displacement in the primary space-temporality by the spoken word. So, for something to appear and live, the spoken word is required. Even the divine dream appears as a pre-word of a creator’s thought. The thought follows the spoken word, the spoken word follows the gestures which finally indicate the meanings of the creative act, controlling the rhythm of the creation days. These three will later be adapted through imitation in rite. We are now situated at the limit of the physical world, a real challenge for the mythical imagery. The general feature of the mythical expression on the creation of the material world is the state of the divinity’s exhaustion, most often conceptualized by sacrifice or divine fatigue. The world geography identifies with the anatomy of a self-gutted god. Practically, material creation is most likely the complete revelation of God’s body autopsy. As each body decomposes, everything in it is an illusion. An axial approach of the phenomenon exists in all religious systems. The created element’s origin is exterior, with or without a pre-existing matter, by a god’s sacrifice or only because it has to be that way. This is the starting point of the discussion on the symbolism of axiality as a reason for the constitution of the language of creation, capable of retelling the imaginary construction of myth in an oral and then written form.

This chapter examines the challenge for entrepreneurial companies of going beyond the start-up phase and growing into large successful companies. We examine the long-term financing of these so-called scale-up companies, focusing on the United States, Europe, and Canada. The chapter first provides a conceptual framework for understanding the challenges of financing scale-ups. It emphasizes the need for investors with deep pockets, for smart money, for investor networks, and for patient money. It then shows some data about the various aspects of financing scale-ups in the United States, Europe, and Canada, showing how Europe and Canada are lagging behind the US relatively more at the scale-up than the start-up stage. Finally, the chapter raises the question of long-term public policies for supporting the creation of a better scale-up environment.

Abstract:This article examines the digitization policy of Archives du Maroc (AdM), Morocco’s national archival institution, which was set up in 2011 and opened in 2013. Given its recent creation, the AdM lead us to question the particularity of digitization in archiving policies when included from the start rather than retroactively. Through an analysis of the creation and development of AdM as a public policy connected to national efforts at transparency and “good governance,” I argue that digitization has served as a way of performing modernity through technology and international standards, thus reinforcing the legitimacy of a nascent institution.

This paper considers an implicit trend in youth ministry to present Jesus as the archetypal superhero and asks if this is a valid and a helpful approach. The paper examines the relationship between the biblical category of hero and the contemporary notion of superhero and a broader appreciation of the use of myth for communicating Christian apologetics as seen in Lewis and Tolkien. The starting point for the paper is that an arguable starting point for the creation of Superman is in the epic character of Hercules and the biblical hero Samson. Through an examination of biblical and other Near East material the paper calls for a deeper and more nuanced appreciation of the relevance of modern western myth in the task of communicating theological narratives and concepts.

This article proposes a framework that automatically designs classifiers for the early detection of COVID-19 from chest X-ray images. To do this, our approach repeatedly makes use of a heuristic for optimisation to efficiently find the best combination of the hyperparameters of a convolutional deep learning model. The framework starts with optimising a basic convolutional neural network which represents the starting point for the evolution process. Subsequently, at most two additional convolutional layers are added, at a time, to the previous convolutional structure as a result of a further optimisation phase. Each performed phase maximises the the accuracy of the system, thus requiring training and assessment of the new model, which gets gradually deeper, with relevant COVID-19 chest X-ray images. This iterative process ends when no improvement, in terms of accuracy, is recorded. Hence, the proposed method evolves the most performing network with the minimum number of convolutional layers. In this light, we simultaneously achieve high accuracy while minimising the presence of redundant layers to guarantee a fast but reliable model. Our results show that the proposed implementation of such a framework achieves accuracy up to 99.11%, thus being particularly suitable for the early detection of COVID-19.

Abstract This paper is the second of a series of two papers which designed a new type of load balancing mechanisms for planetary gearings with arbitrary number of planets. In this paper the common expression of the non-uniform load share factor was deduced, and a function parameter:force-arm factor and their solution was given. That makes it possible that the dimensions and the ability of load equilibrium of Multi-Link Load Balancing Mechanisms can be determined. The criteria of optimum load balancing Mechanisms selection were set up with consider of the effects of turning pair clearances, and optimum mechanisms were selected among the 15 candidates obtained in Part 1. Finally, it was demonstrated that the optimum multi-link load balancing mechanisms for arbitrary number of planets had the similar topological structures and same function and performence of load equilibrium.

This paper documents the set-up and validation of nonlinear autoregressive exogenous (NARX) models of a heavy-duty single-shaft gas turbine. The considered gas turbine is a General Electric PG 9351FA located in Italy. The data used for model training are time series data sets of several different maneuvers taken experimentally during the start-up procedure and refer to cold, warm and hot start-up. The trained NARX models are used to predict other experimental data sets and comparisons are made among the outputs of the models and the corresponding measured data. Therefore, this paper addresses the challenge of setting up robust and reliable NARX models, by means of a sound selection of training data sets and a sensitivity analysis on the number of neurons. Moreover, a new performance function for the training process is defined to weigh more the most rapid transients. The final aim of this paper is the set-up of a powerful, easy-to-build and very accurate simulation tool which can be used for both control logic tuning and gas turbine diagnostics, characterized by good generalization capability.

Purpose – The purpose of this paper is to investigate entrepreneurs’ network evolution in the start-up phase. Design/methodology/approach – Based on the case studies of six fashion start-up firms, this study uses a three-dimensional perspective on social capital (structural, relational, cognitive) to investigate entrepreneurs’ network evolution (i.e. initiation of new relationships) in the start-up phase so as to acquire resources and support for firms’ goals. The study focuses particularly on the understudied cognitive dimension of social capital. The fashion industry provides a relevant research setting because it is characterised by changes in demand, which generate opportunities for entrepreneurship. Findings – The findings show that the display of cognitive attributes is important for the creation of structural social capital (the establishment of new relationships). The findings also indicate that relationships initiated based on the cognitive dimension have a high probability of developing into embedded relationships, thereby becoming high in the relational dimension and providing access to private information containing referrals to other actors. Thus, these relationships also promote the continued development of the structural dimension. Originality/value – The findings imply that the entrepreneurs’ sets of cognitive attributes constitute an important asset in the creation of social capital. They also point to the importance of signalling these values to potential resource holders. Relationships initiated through the display of cognitive attributes can provide resources without requiring immediate economic remuneration.

In recent years, the anammox process has emerged as a useful method for robust and efficient nitrogen removal in wastewater treatment plants (WWTPs). This paper evaluates a one-stage deammonification (nitritation and anammox) start-up using carrier material without using anammox inoculum. A continuous laboratory-scale process was followed by full-scale operation with reject water from the digesters at Bekkelaget WWTP in Oslo, Norway. A third laboratory reactor was run in operational mode to verify the suitability of reject water from thermophilic digestion for the deammonification process. The two start-ups presented were run with indigenous bacterial populations, intermittent aeration and dilution, to favour growth of the anammox bacterial branches. Evaluation was done by chemical and fluorescence in situ hybridization analyses. The results demonstrate that anammox culture can be set up in a one-stage process only using indigenous anammox bacteria and that a full-scale start-up process can be completed in less than 120 days.
