As an entrepreneurial activity, implementing coopetition involves changing the relationships between players and modifying deeply their frames of reference. Our goal is to investigate the change process associated with the implementation of coopetition as institutional change. By conducting fifty-nine interviews and many observations with an abductive grounded theory approach, we uncover four phases of the coopetition process between winemakers and highlight the ability of these entrepreneurs to skillfully combine institutional logics to achieve economic performance. We discuss the implications of our findings for the literature on coopetition and institutional entrepreneurs’ roles in the coopetition process. [less ▲]

Winemakers in South France combine contingently institutional logics to achieve economic performance. Entrepreneurs who decide to cooperate with their competitors must manage four phases of “coopetition”: launch, formalization, protection, and reinforcement. They engage in the coopetition process by referring to a professional logic that becomes dominant, and they complete the process by fostering a community logic that is combined with the professional logic. Identity and legitimacy are the key elements that entrepreneurs segregate and blend, which entails new combinations in the respective influential power of state logic, professional logic and community logic.

The automatic detection of eye positions, their temporal consistency, and their mapping into a line of sight in the real world (to find where a person is looking at) is reported in the scientific literature as gaze tracking. This has become a very hot topic in the field of computer vision during the last decades, with a surprising and continuously growing number of application fields. A very long journey has been made from the first pioneering works, and this continuous search for more accurate solutions process has been further boosted in the last decade when deep neural networks have revolutionized the whole machine learning area, and gaze tracking as well. In this arena, it is being increasingly useful to find guidance through survey/review articles collecting most relevant works and putting clear pros and cons of existing techniques, also by introducing a precise taxonomy. This kind of manuscripts allows researchers and technicians to choose the better way to move towards their application or scientific goals. In the literature, there exist holistic and specifically technological survey documents (even if not updated), but, unfortunately, there is not an overview discussing how the great advancements in computer vision have impacted gaze tracking. Thus, this work represents an attempt to fill this gap, also introducing a wider point of view that brings to a new taxonomy (extending the consolidated ones) by considering gaze tracking as a more exhaustive task that aims at estimating gaze target from different perspectives: from the eye of the beholder (first-person view), from an external camera framing the beholder’s, from a third-person view looking at the scene where the beholder is placed in, and from an external view independent from the beholder.

A neoliberal and globally organized social work is the focus of this presentation, which discusses the very first results of an transnational research project on cross-border child protection and disability rights in the Greater Region including Belgium, Germany, France and Luxembourg (EUR&QUA) According to UN Conventions (UNCRC, 1990 and UNCRPD, 2006), States Parties shall ensure and promote the full realisation of all human rights and fundamental freedoms for all children and persons with disabilities. Essentially, the Conventions call upon States Parties to take legislative, administrative and other measures to implement the rights recognised in both Conventions. Such imperatives seem to contradict a neoliberal social policy, which is oriented towards restraint in market intervention, strict austerity and cost reduction, and individualisation of social problems (Cummins, 2018). Actually, initial research results suggest that cross-border social work care for children and their families is not always sufficient. Crossing the border often means breaking off helping relations in the home country and there is hardly any professional exchange between social work providers involved. As a result, a return to the original life context desired by the clients seems hardly feasible (EUR&QUA 2019). Furthermore, practitioners expressed concern that diagnoses and support needs were formulated with a targeted focus on care in a neighbouring country. The research also identified cases that were not in line with the Brussels-II-Treaty on cross-border custody procedures. Some results may be derived less from optimal child protection and disability rights than from neo-liberalism, managerialism and austerity. In order to counter this development, social work needs something like Machiavellian competences (Kusiak, 2018; Drouard, 2008), which consist of critically illuminating a dominant ideology, conducting empirical research and acquiring the corresponding strategic knowledge. To this end, the research project aims to establish a Master's programme to empower future social worker in cross-boarder protection tasks. [less ▲]

Against the background of neoliberal and globally organized social work, the presentation discusses the very first results of the international research project on cross-border child protection and disability rights in transnational settings (EUR&QUA). According to international Conventions (UNCRC, 1990; UNCRPD, 2006), States parties shall ensure the full realization of all human rights and fundamental freedoms for all children. Such imperatives seem to contradict neoliberal social policy, which is primarily oriented towards marketisation, austerity, and individualisation of social problems (Cummins, 2018). Actually, our research suggests that crossing borders often means breaking off helping relations and absence of professional exchange between care providers. A return to the original life context desired by the clients seems unfeasible. Therefore, we plead for social workers to acquire global, and cross-border competences in this field. Social work needs Machiavellian competences (Kusiak, 2018), which consist of critically illuminating a dominant ideology, conducting research, and acquiring strategic knowledge. [less ▲]

Learning how to count is a crucial step in cognitive development, which progressively allows for more elaborate numerical processing. The existing body of research consistently reports how children associate the verbal code with exact quantity. However, the early acquisition of this code, when the verbal numbers are encoded in long-term memory as a sequence of words, has rarely been examined. Using an incidental assessment method based on serial recall of number words presented in ordered versus non-ordered sequences (e.g., one-two-three vs. two-one-three), we tracked the progressive acquisition of the verbal number sequence in children aged 3-6 years. Results revealed evidence for verbal number sequence knowledge in the youngest children even before counting is fully mastered. Verbal numerical knowledge thus starts to be organized as a sequence in long-term memory already at the age of 3 years, and this numerical sequence knowledge is assessed in a sensitive manner by incidental rather than explicit measures of number knowledge.

We introduce labor contracts in a framework of optimal redistribution: firms have some local market power and try to discriminate among heterogeneous workers. In this setting we show that if the firms have perfect information, i.e., they perfectly discriminate against workers and take all the surplus, the best tax function is flat. If firms have imperfect information, i.e., if they offer incentive contracts, then (under some assumptions) the best redistributive taxation is regressive. [less ▲]

Reflecting intelligent surfaces (RIS) is a low-cost and energy-efficient solution to achieve high spectral efficiency in sixth-generation (6G) networks. The basic idea of RIS is to smartly reconfigure the signal propagation by using passive reflecting elements. On the other side, the demand of high throughput geostationary (GEO) satellite communications (SatCom) is rapidly growing to deliver broadband services in inaccessible/insufficient covered areas of terrestrial networks. This paper proposes a GEO SatCom network, where a satellite transmits the signal to a ground mobile terminal using multicarrier communications. To enhance the effective gain, the signal delivery from satellite to the ground mobile terminal is also assisted by RIS which smartly shift the phase of the signal towards ground terminal. We consider that RIS is mounted on a high building and equipped with multiple re-configurable passive elements along with smart controller. We jointly optimize the power allocation and phase shift design to maximize the channel capacity of the system. The joint optimization problem is formulated as nonconvex due to coupled variables which is hard to solve through traditional convex optimization methods. Thus, we propose a new optimal algorithm which is based on Mesh Adaptive Direct Search to obtain an efficient solution. Simulation results unveil the benefits of RIS-assisted SatCom in terms of system channel capacity. [less ▲]

Numerous behavioural studies indicate the existence of a link between numerical representations and visuo-spatial processes (for review see DeHevia et al., 2008). A striking demonstration of this link was provided by Fischer and colleagues (2003), who reported that participants detect a target faster in the left hemifield, if preceded by a small number (e.g. 2 or 3) and faster in the right hemifield if preceded by a large number (e.g. 8 or 9). This is strong evidence that numbers orient visuo-spatial attention to the left or right hemifield, depending on their magnitude (e.g., small and large, respectively) (see also Galfano et al., 2006; Ristic et al., 2006). We designed a modified version of this target detection paradigm, by replacing the detection task with a target discrimination task (cf. Hommel et al., 2001). The participants (n=16) were presented 1 task irrelevant digit (1,2 vs. 8,9) for 400ms. After a variable inter-stimulus interval (500, 1000 or 2000ms), they had to discriminate the colour of a brief (100ms) lateral target. We hypothesized that the centrally presented numbers would induce an orientation of attention, in the same direction as the initial observations by Fischer et al. (2003). The current results indicate a significant effect, but only for the shortest digit-target interval (500ms). We observed a significant interaction between number magnitude (small/large) and side of target presentation (left/right) (F1,15 =7.784, p<0.014). These findings indicate that the attentional shifts induced by irrelevant numerical material are independent of the exact nature of target processing (discrimination vs. detection). [less ▲]
