Abstract In this paper, we study 5d $$ \mathcal{N} $$ N = 1 Sp(N) gauge theory with Nf (≤ 2N + 3) flavors based on 5-brane web diagram with O5-plane. On the one hand, we discuss Seiberg-Witten curve based on the dual graph of the 5-brane web with O5-plane. On the other hand, we compute the Nekrasov partition function based on the topological vertex formalism with O5-plane. Rewriting it in terms of profile functions, we obtain the saddle point equation for the profile function after taking thermodynamic limit. By introducing the resolvent, we derive the Seiberg-Witten curve and its boundary conditions as well as its relation to the prepotential in terms of the cycle integrals. They coincide with those directly obtained from the dual graph of the 5-brane web with O5-plane. This agreement gives further evidence for mirror symmetry which relates Nekrasov partition function with Seiberg-Witten curve in the case with orientifold plane and shed light on the non-toric Calabi-Yau 3-folds including D-type singularities.

The current study intends to contribute to a better understanding of the medical tourism experience. In particular, this study uses data from a survey-based study conducted on a sample of 1,209 medical tourists in Croatia. On the one hand, this study aims to explore and shed light on the decision-making process of medical tourists, and, on the other hand, to reveal which elements of both the medical institution and the destination where it is located, have largest potentials to drive medical tourist delight and/or frustration, in accordance with the three-factor theory of customer satisfaction.

Starting from previous studies in professional caregivers of people with dementia and other diseases in institutionalized centers of different regions, the aim of this study was to compare burnout levels that workers present depending on the center, to create a caregiver profile with high professional accomplishment and to describe the quality of life that residents perceive Murcia and Barcelona. The instruments used were the Maslach Burnout Inventory (MBI), the Professional Caregiver Survey developed ad hoc and the Brief Questionnaire of Quality of Life (CUBRECAVI in Spanish) on residents. The results show, on the one hand, that levels of professional accomplishment may be paradoxically higher in the case of catastrophe and, on the other hand, the 98.2% of users are satisfied with the residence in which is located and 81.8% with the manner in which occupy the time. The conclusions that are extrapolated from the study shed light on the current situation of workers and residents and the influence that an earthquake can have on them.

This article first aims to demonstrate the different ways the work of the English neurologist John Hughlings Jackson influenced Freud. It argues that these can be summarized in six points. It is further argued that the framework proposed by Jackson continued to be pursued by twentieth-century neuroscientists such as Papez, MacLean and Panksepp in terms of tripartite hierarchical evolutionary models. Finally, the account presented here aims to shed light on the analogies encountered by psychodynamically oriented neuroscientists, between contemporary accounts of the anatomy and physiology of the nervous system on the one hand, and Freudian models of the mind on the other. These parallels, I will suggest, are not coincidental. They have a historical underpinning, as both accounts most likely originate from a common source: John Hughlings Jackson's tripartite evolutionary hierarchical view of the brain.

This text is part of a research conducted under the working title "What do we talk about when we are silent and what are we silent about when we are talking? - premises for the anthropology of silence about the nearest past." In the first part the author investigates the meaning of silence in the Croatian and Serbian press right before and during Croatia's Operation Storm. The ratio between silence, suppression of information and forgetting, on the one hand, and social memory, on the other, has been elaborated in the final part of the text by following reports about the anniversaries of Operation Storm in both Croatian and Serbian publics. The starting point lies in the belief that the phenomenon of silence (and suppression of information), being an immanent part of each discourse, represents an important factor in the creation of social relationships and system of value models, that it has important communication and cognitive functions and that the performance character lies in its essence. In short, silence makes it possible to form the prevailing image about this event, even if it does not construct it indirectly - through speech. The author has elaborated on the meaning of silence in the context of Operation Storm partly because studies about the breakup of Yugoslavia frequently mention silence as a manipulation strategy employed by some of the sides in the conflict (or analysts dealing with Yugoslav topics), while not a single study systematically investigates the semantic of silence and suppression of information in these conflicts. Most importantly, taking into account the frequency of direct silence in the newspaper discourse and rhetoric strategies that point at silence indirectly from the context and discourse, the author focuses on the relationship between the event (situation) and silence. In order to shed light on the way in which Operation Storm is remembered, i.e. forgotten, in the stakeholders' publics and political imageries, she follows the dailies - Vecernje Novosti Politika, Danas (Belgrade) - Vecernji List, Jutarnji List, Magazin supplement of the Jutarnji List (Zagreb), as well as texts about Operation Storm in weeklies such as the NIN and Vreme of Belgrade or Globus of Zagreb in the period between August 2, 1995 and mid-August 2006.

My aim in this article is to develop a possible understanding of Adorno’s thoughts on musical interpretation as they appear in a collection of fragments posthumously published in 2001 under the title of Zu einer Theorie der musikalischen Reproduktion [Towards a Theory of Musical Reproduction]. I do this by using an actual sounding example, with emphasis on the dialectical relationship between the written text and the sounding realization. On the one hand, I use a passage by Beethoven (Symphony No. 1, First Movement) that is characterized by some philological uncertainties regarding articulation, explained in slightly different ways in three so-called Urtext-editions of the score. On the other hand, I use a recorded interpretation of the Vienna Philharmonic Orchestra conducted by Austrian Nikolaus Harnoncourt. I will argue that, in this performance, Harnoncourt’s articulation of the actual passage provides a useful illustration of the tension between text and sound. Moreover, as the interpretation is also musically intriguing, it seems to function as a thought-provoking example of the dialectical relationship which for Adorno characterizes a successful musical interpretation. Thus, the article aims to shed light on both Adorno’s somewhat intricate speculations and Harnoncourt’s personal practice of interpretation.

According to Chomsky’s report of the mid 1970s, he and Harris developed their theories in an essentially independent way; whereas according to some statements by Harris, some contact actually took place between them. To shed light on this issue, it may be useful to systematically compare their respective views of the notion ‘transformation’ as well as their analyses of certain syntactic phenomena. Among the topics dealt with in the present article are: the system of syntactic categories and their symbols; the notion of ‘zero elements’; the phenomenon of discontinuous constituents; the English auxiliary system; wh-constructions; the typology of transformations; the notions of ‘kernel’ and ‘kernel sentence’. Several of these analyses show many points of contact between the two scholars (e.g., the analysis of wh-constructions or that of English auxiliaries), which allow us to maintain that they surely influenced each other. The overall differences between the two models are also clear: the transformational relation holds between sentences in Harris’s framework, while it holds between underlying strings on the one hand and actual sentences on the other in Chomsky’s. As a consequence of this different view of the notion of transformation, two problems which were fundamental for Chomsky had no importance for Harris, namely the order of transformations and the distinction between optional and obligatory transformations. It can therefore be concluded that, if the two scholars certainly influenced each other when they were working out their respective transformational theories, their theoretical views were acutely different almost from the beginning.

The psychoanalytic interpretation of Salafi jihadism and terrorism, or the application of psychoanalytic categories to said issues, are not very common. Indeed the mobilization of psychoanalysis in this context very often prompts accusations of orientalism and cultural imperialism. Both academic discourse and, to a lesser extent, policy, tend to “explain,” whether genuinely, strategically or tactically, or diplomatically, the emergence of “home-grown” Salafism by pointing to social, welfare, or educational deficits in the jihadists’ biographies. In this article we make an attempt to focus on psychoanalysis (or “depth psychology,” as it was sometimes called in a now-bygone age) to shed light on the phenomenon. Taking cues from Jan Hendrik van den Berg’s neo-Freudian and phenomenology-inspired critique of classical psychoanalysis on the one hand, and Peter Sloterdijk’s recent work on bastardy on the other, we offer a reading of European home-grown Salafi jihadist and terrorist inclination as reactions to failure, and as manifestations of a deep sense of inadequacy, in some of those who are unable to live up to what has become the predominant, imperative code in the cultural mainstream: to live one’s life in radical, complete, and total sovereignty, undetermined and in absolute omnipotence. This code, and the exigencies it imposes, we suggest, have become mainstream in the age which we have called Luciferian.

Part 1 of this paper was concerned principally with the various problems that confront any attempt to provide a satisfactory transcription of these two examples. Given the nature of the difficulties encountered, it is clear that any generalizations we might wish to derive from them can only be tentative and provisional. Nevertheless, the paucity of comparable material, which on the one hand renders the interpretative hurdles all the more difficult to surmount, on the other makes the urge to draw at least some conclusions from the material provided by ‘Abd al-Qādir al-Marāghī and Binā'ī well-nigh irresistible. Such conclusions would involve, essentially, an assessment of the extent to which their notations shed light on the musical practice of the period and provide reliable evidence for the history of composition and styles of textsetting. But in any evaluation of this nature it is essential to avoid the temptation to confuse the sources with the speculative editorial interventions that produce the versions presented in part 1 (exs. 26–8 and 30). The area about which least can be said with regard to the naqsh notated by Binā'ī is, therefore, the nature of the text-setting, while with regard to ‘Abd al-Qādir al-Marāghī's notations it is, rather, the first topic we may consider, the relationship between melody and the underlying articulation of the rhythmic cycle.

This paper aims to explore how Palestinian Arab and Jewish university students in Israel, attending a course on conflict resolution, deal with their stereotypical views of the Other and their prejudices, as well as their complex emotions of fear, hate, anxiety, and love during a period of tension and violence. On the one hand, they have a natural desire for professional partnership and friendship with their fellow students. On the other hand, they are attending this class in a Jewish university, in the heart of the Middle East, where acts of terrorism occur almost daily. This violence changes the power structure and the dynamics of their mutual relationships. Through an analysis of a specific case study the paper aims to shed light on how bridging theory and practice can generate a better understanding of complex situations, enabling reflection and developing signposts to improve coping mechanisms within peace education frameworks in times of terror.

Wonder is undoubtedly a term that floats around in today’s academic discussion both on ancient philosophy and on philosophy of education. Back in the 4th century B.C., Aristotle underlined the fact that philosophy begins in wonder (θαυμάζειν), without being very specific about the conditions and the effects of its emergence. He focused a great deal on children’s education, emphasizing its fundamental role in human beings’ moral fulfillment, though he never provided a systematic account of children’s moral status. The aim of this paper is to examine, on the one hand, if, to what extent, and under what conditions, Aristotle allows for philosophical wonder to emerge in children’s souls, and, on the other hand, how his approach to education may shed light to the link between wonder and the ultimate moral end, i.e. human flourishing. We will, thus, 1) try to offer a unified outlook of the philosopher’s views on children’s special cognitive and moral state, and 2) illustrate how wonder contributes in overcoming their imperfect state of being.
