    UKRAINE CRISIS AS A GLOBAL SECURITY CHALLENGE

    Get PDF
    Russia’s invasion of Ukraine - Europe’s worst security crisis in decades - has prompted the EU to make unprecedented decisions on EU security, defence and enlargement. For the first time, decisions have been made to deliver deadly weapons to a third country and decisions to strengthen defence co-operation amid a new perception of the threat. The 2001 Temporary Protection Directive, which grants temporary residence to Ukrainian refugees, was activated for the first time. The overwhelming support for the UN resolution condemning the Russian invasion clearly proves that countries around the world see the invasion as an attack on global norms. However, policy makers in certain countries are managing the crisis in terms of their national interest. This paper will analyse the differences in regional and national attitudes regarding the events in Ukraine, ie geopolitical, economic and security factors that influence decision-making to deal with the Ukrainian crisis

    Quantum chaos and thermalization in the two-mode Dicke model

    Full text link
    We discuss the onset of quantum chaos and thermalization in the two-mode Dicke model, which describes the dipolar interaction between an ensemble of spins and two bosonic modes. The two-mode Dicke model exhibits normal to superradiant quantum phase transition with spontaneous breaking either of a discrete or continuous symmetry. We study the behaviour of the fidelity out-of-time-order correlator derived from the Loschmidt echo signal in the quantum phases of the model and show that its exponential growth cannot be related to a classical unstable point in the general case. Moreover, we find that the collective spin observable in the two-mode Dicke model quickly saturates to its long-time average value, and shows very good agreement between its diagonal ensemble average and microcanonical average even for a small number of spins. We show that the temporal fluctuations of the expectation value of the collective spin observable around its average are small and decrease with the effective system size, which leads to thermalization of the spin system.Comment: 8 pages, 6 figures, (v2) updated appendi

    Second language pronunciation: a summary of teaching techniques

    Get PDF
    The aim of the paper is to give a critical summary of the traditional and more alternative techniques and activities for pronunciation practice recommended in the literature. In the past few decades the theoretical approaches to teaching pronunciation have changed considerably, from giving a strong focus on the accurate production of individual speech sounds to shifting the focus onto the greater communicative relevance of connected speech and intelligibility. Approaching L2 pronunciation teaching is not an easy task, and it needs to be systematically dealt with. The paper discusses several decisions teachers need to make when choosing activities for pronunciation practice: selecting the type of phonological structure to practice, deciding on the speech mode, determining the structural level of practice, focusing on a particular type of instruction, establishing the degree of control of the structure that is practiced, and choosing which cognitive skill to enhance while practicing. With regard to the various techniques for teaching pronunciation, the analysis shows they have adapted accordingly in line with the different trends. Hence, while traditional activities such as automatic repetition, ear-training and explicit phonetic instruction are still considered effective, additional priority is given to activities for raising phonological awareness, communicative activities and techniques that adopt an interdisciplinary approach

    The English pronunciation teaching in Europe survey: selected results

    Get PDF
    The results of EPTiES reveal interesting phenomena across Europe, despite shortcomings in terms of construction and distribution. For example, most respondents are non-native speakers of English and the majority of them rate their own mastery of English pronunciation favourably. However, most feel they had little or no training in how to teach pronunciation, which begs the question of how teachers are coping with this key aspect of language teaching. In relation to target models, RP remains the variety of English which teachers claim to use, whilst recognizing that General American might be preferred by some students. Differences between countries are explored, especially via replies to open-ended questions, allowing a more nuanced picture to emerge for each country. Other survey research is also referred to, in order to contextualise the analyses and implications for teaching English and for training English teacher

    Application of the Rey-Osterrieth complex figure test for assessment of cognitive impairment in multiple sclerosis

    Get PDF
    INTRODUCTION: Cognitive impairment is frequent in multiple sclerosis and predominantly affects visuospatial abilities, memory, attention, and executive functions. Because of the specific cognitive profile, different from that in Alzheimer's disease and other frequent disorders presenting with dementia, specific neuropsychological instruments need to be used in multiple sclerosis. The aim of the present study is to assess the applicability of the Rey-Osterrieth complex figure test (ROCFT) for assessing cognitive impairment in patients with multiple sclerosis in comparison with a control group.MATERIAL AND METHODS: One hundred and two persons, 70 patients with MS and 32 healthy control subjects were assessed using ROCFT. A standardized system for assessment by points and percentiles was used. The results of both groups were compared statistically using independent samples t-test.RESULTS: On the copying task, the differences between patients and controls reached statistical significance, p<0.05 for the raw score, and p<0.001 after results were grouped by percentiles. On the drawing by memory task the differences between the two groups also showed statistical significance, p<0.01.CONCLUSION: ROCFT shows statistically significant differences between patients with multiple sclerosis and healthy subjects. Highest levels of significance were observed for copying, scored by percentiles, and for drawing by memory. The application of ROCFT can provide valuable information about cognitive dysfunction in multiple sclerosis

    Smoothie or Fruit Salad? Learners’ Descriptions of Accents as Windows to Concept Formation

    Get PDF
    This paper explores the linguistically naive descriptions which one set of EFL learners provided when identifying and describing accents. First and second-year English majors at a French university were asked to do two tasks. First, they listened to two extracts to determine whether the speaker’s accent sounded more British or American, and to explain which features helped them to decide. Later they answered two questions: a) What do you do when you want to sound more like an American? and b) more like a British person? The analysis of their answers highlights learners’ underlying representations of accents as well as concept formation in relation to English pronunciation. I argue that this cognitive aspect of L2 learning should be addressed explicitly in instruction

    Breaking the Barriers: ontological aspects of relation and mutuality in contemporary theories of atomic structure and in philosophy of personalism

    Get PDF
    Also published in Symposium Melitensia Vol. 15 (2019) p. 17-28The paper focuses on the interdisciplinary field between the sciences and the humanities. It explores the subject matter of breaking barriers and ‘individuality’ in terms of the subatomic particles as building blocks of the matter and the human beings according to existentialism and personalism as philosophical traditions. The ‘overcoming the barrier’ theme is considered in a twofold perspective in this paper: on the one hand, as an ontological, structural and organisational principle, and, on the other hand as a condition for interaction, relation and mutuality. Theoretical and conceptual references to some of the fundamental ideas and concepts of the Quantum Mechanical Model of the atom and the Standard Model of particles are made, emphasising the primary importance of the entanglement as the variation of relationality and mutuality in the field of natural sciences. Moreover, references are made as well as to Martin Buber’s and Emmanuel Lévinas’s philosophy. This paper will serve as a basis for the development of an interdisciplinary series of seminars in the Secondary school curriculum aiming to deepen the relation between the natural sciences (chemistry and physics) and the humanities.peer-reviewe

    Adiabatic sensing technique for optimal temperature estimation using trapped ions

    Get PDF
    We propose an adiabatic method for optimal phonon temperature estimation using trapped ions which can be operated beyond the Lamb-Dicke regime. The quantum sensing technique relies on a time-dependent red-sideband transition of phonon modes, described by the nonlinear Jaynes-Cummings model in general. A unique feature of our sensing technique is that the relevant information of the phonon thermal distributions can be transferred to the collective spin-degree of freedom. We show that each of the thermal state probabilities is adiabatically mapped onto the respective collective spin-excitation configuration and thus the temperature estimation is carried out simply by performing a spin-dependent laser fluorescence measurement at the end of the adiabatic transition. We characterize the temperature uncertainty in terms of the Fisher information and show that the state projection measurement saturates the fundamental quantum Cramér-Rao bound for a quantum oscillator at thermal equilibrium

    Cancer and systemic inflammation: treat the tumour and treat the host

    Get PDF
    Determinants of cancer progression and survival are multifactorial and host responses are increasingly appreciated to have a major role. Indeed, the development and maintenance of a systemic inflammatory response has been consistently observed to confer poorer outcome, in both early and advanced stage disease. For patients, cancer-associated symptoms are of particular importance resulting in a marked impact on day-to-day quality of life and are also associated with poorer outcome. These symptoms are now recognised to cluster with one another with anorexia, weight loss and physical function forming a recognised cluster whereas fatigue, pain and depression forming another. Importantly, it has become apparent that these symptom clusters are associated with presence of a systemic inflammatory response in the patient with cancer. Given the understanding of the above, there is now a need to intervene to moderate systemic inflammatory responses, where present. In this context the rationale for therapeutic intervention using nonselective anti-inflammatory agents is clear and compelling and likely to become a part of routine clinical practice in the near future. The published literature on therapeutic intervention using anti-inflammatory agents for cancer-associated symptoms was reviewed. There are important parallels with the development of useful treatments for the systemic inflammatory response in patients with rheumatological disease and cardiovascular disease
