Which European public order? Sources of imbalance in the European area of freedom, security and justice

ABSTRACT The creation of the Single European Market has been accompanied by an intense discussion on whether market-creating measures have been privileged over market- correcting ones by the institutional system of the EU. The creation of an ‘Area of Freedom, Security and Justice' (AFSJ) launched by the Treaty of Amsterdam poses a similar question which, however, has remained heavily under-researched: will the balance between policing competencies and individual rights shift towards the former at the expense of the latter? Recent work on the ‘new raison d'e ́tat' and the strengthening of national executives in processes of Europeanisation points in this direction. This essay explores the parallels between the Common Market and the AFSJ with regard to the relationship between the structures and substance of governance. The balance between security and individual rights is scrutinised in the main pillars of the AFSJ: asylum cooperation, judicial cooperation in criminal matters and police cooperation

Labour Market Integration, Remittances and Optimal Tax Policy

This paper, using a model comprising two labour sending countries and one labour receiving country, analyses the optimal tax/subsidy policies of countries to control international migration when labour markets are integrated. The analysis shows that the countries of emigration should tax the migrants to maximise national income. This result suggests that the developing and transitional countries need to re-evaluate their policies of supporting migration. The optimal policy of the receiving country is to use discriminatory tax rates where the sending country with higher labour endowment bears a higher tax burden

Implementing Learning Principles with a Personal AI Tutor: A Case Study

Effective learning strategies based on principles like personalization, retrieval practice, and spaced repetition are often challenging to implement due to practical constraints. Here we explore the integration of AI tutors to complement learning programs in accordance with learning sciences. A semester-long study was conducted at UniDistance Suisse, where an AI tutor app was provided to psychology students taking a neuroscience course (N=51). After automatically generating microlearning questions from existing course materials using GPT-3, the AI tutor developed a dynamic neural-network model of each student's grasp of key concepts. This enabled the implementation of distributed retrieval practice, personalized to each student's individual level and abilities. The results indicate that students who actively engaged with the AI tutor achieved significantly higher grades. Moreover, active engagement led to an average improvement of up to 15 percentile points compared to a parallel course without AI tutor. Additionally, the grasp strongly correlated with the exam grade, thus validating the relevance of neural-network predictions. This research demonstrates the ability of personal AI tutors to model human learning processes and effectively enhance academic performance. By integrating AI tutors into their programs, educators can offer students personalized learning experiences grounded in the principles of learning sciences, thereby addressing the challenges associated with implementing effective learning strategies. These findings contribute to the growing body of knowledge on the transformative potential of AI in education.Comment: 17 pages, 7 figure

Low-Resolution Place and Response Learning Capacities in Down Syndrome.

Down syndrome (DS), the most common genetic cause of intellectual disability, results from the partial or complete triplication of chromosome 21. Individuals with DS are impaired at using a high-resolution, allocentric spatial representation to learn and remember discrete locations in a controlled environment. Here, we assessed the capacity of individuals with DS to perform low-resolution spatial learning, depending on two competing memory systems: (1) the place learning system, which depends on the hippocampus and creates flexible relational representations of the environment; and (2) the response learning system, which depends on the striatum and creates fixed stimulus-response representations of behavioral actions. Individuals with DS exhibited a preservation of the low-resolution spatial learning capacities subserved by these two systems. In place learning, although the average performance of individuals with DS was lower than that of typically developing (TD) mental age (MA)-matched children and TD young adults, the number of individuals with DS performing above chance level did not differ from TD children. In response learning, the average performance of individuals with DS was lower than that of TD adults, but it did not differ from that of TD children. Moreover, the number of individuals with DS performing above chance level did not differ from TD adults, and was higher than that of TD children. In sum, whereas low-resolution place learning appears relatively preserved in individuals with DS, response learning appears facilitated. Our findings are consistent with the hypothesis that the neural pathways supporting low-resolution place learning and response learning are relatively preserved in DS

Odor supported place cell model and goal navigation in rodents

Experiments with rodents demonstrate that visual cues play an important role in the control of hippocampal place cells and spatial navigation. Nevertheless, rats may also rely on auditory, olfactory and somatosensory stimuli for orientation. It is also known that rats can track odors or self-generated scent marks to find a food source. Here we model odor supported place cells by using a simple feed-forward network and analyze the impact of olfactory cues on place cell formation and spatial navigation. The obtained place cells are used to solve a goal navigation task by a novel mechanism based on self-marking by odor patches combined with a Q-learning algorithm. We also analyze the impact of place cell remapping on goal directed behavior when switching between two environments. We emphasize the importance of olfactory cues in place cell formation and show that the utility of environmental and self-generated olfactory cues, together with a mixed navigation strategy, improves goal directed navigation

Pathway-Specific Utilization of Synaptic Zinc in the Macaque Ventral Visual Cortical Areas

Synaptic zinc is an activity-related neuromodulator, enriched in hippocampal mossy fibers and a subset of glutamatergic cortical projections, exclusive of thalamocortical or corticothalamic. Some degree of pathway specificity in the utilization of synaptic zinc has been reported in rodents. Here, we use focal injections of the retrograde tracer sodium selenite to identify zinc-positive (Zn+) projection neurons in the monkey ventral visual pathway. After injections in V1, V4, and TEO areas, neurons were detected preferentially in several feedback pathways but, unusually, were restricted to deeper layers without involvement of layers 2 or 3. Temporal injections resulted in more extensive labeling of both feedback and intratemporal association pathways. The Zn+ neurons had a broader laminar distribution, similar to results from standard retrograde tracers. After anterograde tracer injection in area posterior TE, electron microscopic analysis substantiated that a proportion of feedback synapses was colabeled with zinc. Nearby injections, Zn+ intrinsic neurons concentrated in layer 2, but in temporal areas were also abundant in layer 6. These results indicate considerable pathway and laminar specificity as to which cortical neurons use synaptic zinc. Given the hypothesized roles of synaptic zinc, this is likely to result in distinct synaptic properties, possibly including differential synaptic plasticity within or across projections

Paradigmatic or Critical? Resilience as a New Turn in EU Governance for the Neighbourhood

Rising from the margins of EU aid documents, resilience became a centrepiece of the 2016 EU Global Security Strategy, especially in relation to the neighbourhood. While new resilience-thinking may signify another paradigmatic shift in EU modus operandi, the question that emerges is whether it is critical enough to render EU governance a new turn, to make it sustainable? This article argues that in order for resilience-framed governance to become more effective, the EU needs not just engage with ‘the local’ by way of externally enabling their communal capacity. More crucially, the EU needs to understand resilience for what it is – a self-governing project – to allow ‘the local’ an opportunity to grow their own critical infrastructures and collective agency, in their pursuit of ‘good life’. Is the EU ready for this new thinking, and not just rhetorically or even methodologically when creating new instruments and subjectivities? The bigger question is whether the EU is prepared to critically turn the corner of its neoliberal agenda to accommodate emergent collective rationalities of self-governance as a key to make its peace-building project more successful

Cortical Connections to Area TE in Monkey: Hybrid Modular and Distributed Organization

To investigate the fine anatomical organization of cortical inputs to visual association area TE, 2–3 small injections of retrograde tracers were made in macaque monkeys. Injections were made as a terminal procedure, after optical imaging and electrophysiological recording, and targeted to patches physiologically identified as object-selective. Retrogradely labeled neurons occurred in several unimodal visual areas, the superior temporal sulcus, intraparietal sulcus (IPS), and prefrontal cortex (PFC), consistent with previous studies. Despite the small injection size (<0.5 mm wide), the projection foci in visual areas, but not in IPS or PFC, were spatially widespread (4–6 mm in extent), and predominantly consisted of neurons labeled by only one of the injections. This can be seen as a quasi-modular organization. In addition, within each projection focus, there were scattered neurons projecting to one of the other injections, together with some double-labeled (DL) neurons, in a more distributed pattern. Finally, projection foci included smaller “hotspots,” consisting of intermixed neurons, single-labeled by the different injections, and DL neurons. DL neurons are likely the result of axons having extended, spatially separated terminal arbors, as demonstrated by anterograde experiments. These results suggest a complex, hybrid connectivity architecture, with both modular and distributed components
