The author analyzes Sven Agustijnen's Specters from the philosophical perspective. He tries to prove that the cinema of the Belgian director is haunted because it presents the reality as made out of traces, which disturb the traditional division into presence and absence. The author analyzes Augustijnen's film techniques and uses Jacques Derrida hauntology to show, how contemporary cinema tries to face the difficult and unfinished colonial history of Belgium (the genocide in Congo during the reign of the Belgian king Leopold II and the murder of the first prime minister of the independent Congo, Patrice Lumumba).

Abstract Background: Colletotrichum species are known to engage in unique sexual behaviours that differ significantly from the mating strategies of other filamentous ascomycete species. Most ascomycete fungi require the expression of both the MAT1-1-1 and MAT1-2-1 genes to regulate mating type and induce sexual reproduction. In contrast, all isolates of Colletotrichum are known to harbour only the MAT1-2-1 gene and yet, are capable of recognizing suitable mating partners and producing sexual progeny. The molecular mechanisms contributing to mating types and behaviours in Colletotrichum are thus unknown. Results: A comparative genomics approach analysing genomes from 47 Colletotrichum isolates was used to elucidate a putative molecular mechanism underlying the unique sexual behaviours observed in Colletotrichum species. The existence of only the MAT1-2 idiomorph was confirmed across all species included in this study. Comparisons at the loci harbouring the two mating pheromones and their cognate receptors revealed interesting patterns of gene presence and absence as well as gene loss. The results also showed that these genes have been lost multiple times over the evolutionary history of this genus. Conclusion: The multiple losses of the pheromone genes in these species suggest strong selection against the typical mating strategies seen in other species. This further suggests that these pheromones no longer play a role in mating type determination and that the species of this genus have undiscovered mechanisms by which to control mating type and mating partner recognition. This research thus provides a base from which further interrogation of this topic can take place.


In May, 1907, we* showed that the study of the parasite of sleeping sickness (Trypanosoma gambieme, Dutton), as it appears in the blood of rats artificially infected with the disease, revealed a cyclical metamorphosis, and that this cyclical metamorphosis corresponded closely to the alternating phases of presence and absence of trypanosomes in the blood. At the same time it was found that the cyclical metamorphosis in the parasites corresponded less closely, but still unmistakably corresponded, with the successive alternations of condition that characterise the clinical aspects of the malady in the host. The features of the life-cycle of the parasites of sleeping sickness as they appear in the blood during infection in rats are remarkable, and may be briefly repeated for reference.

AbstractWhat is being? This is, from the Greeks to Hegel (according to Heidegger), the guiding question of ontology and the history of philosophy as metaphysics. And the answer is presence: ‘being’ means ‘being present’, ‘presencing’; ‘to be’ means ‘to be present’. By clarifying the limit of this philosophy of presence, however, it is possible to go beyond it, to a thinking of being as presence and absence—for both coming-to-presence and going-out-into-absence are ways in which beings are, and being happens. And yet, are presence and absence the only ways to think being? On the contrary—there is a third. From the Greeks (through Hegel) to Heidegger, the being that fails to come to presence, but also does not simply remain in absence—this is what is merely implied, an implication. But then what does it mean to think being as implied? Being as implying? As an implication?

Abstract This study examines a recurrent scenario in Roman poetry of the first-person genres: the separation of the poet from his writing tablets. Catullus' tablets are stolen (c.42); Propertius' are lost (3.23); Ovid's (Am. 1.11––12) are consigned to disuse and decay by their disappointed owner. Martial, who does not reproduce the specific narrative of loss, nonetheless engages with the tradition of lost tablets from within the fiction of festive gift-exchange in his Apophoreta (14.1––21): rather than losing or rejecting the tablets, he gives them away to guests/readers at his Saturnalian party. I argue that the representation of writing tablets and their loss is involved in the production of authorial presence. The scene of lost tablets demonstrates how the poet retains the capacity for poetic speech even when deprived of the aid of his material medium. The ostensibly accidental and sometimes lamented loss of the poet's tablets thus contributes to a sophisticated strategy of authorial self-representation. The tablets do not so much stand for the literary text as provide a focus for metapoetic concerns with voice and writing, author and text, presence and absence, immortal ingenium and expendablemateria. Examination of the shifting representation of writing tablets from Catullus to Martial will provide insight into the invention of the Roman poetic author.

The Chronotope of Exile in the Post-Yugoslav Novel and the Boundaries of Imaginary HomelandsAlthough the chronotopic approach to the novels of exile is almost self-explanatory, certain specifics expressed by post-Yugoslav exile narrations evoke a separate chronotope interpretation. First and foremost, post-Yugoslav literature is additionally encumbered with the identity issue because the abandoned areas of the nineties for the exiled writer do not disappear at a metaphorical level, by turning into a mnemotope, but in the actual break-up of the political entity, the imaginary supranational heritage transforms itself into a kind of counterculture, mostly affirmed by exile writers. Therefore, returning to the abandoned place often becomes possible only as a return to the past. In this paper, the literary theme of exile will be followed comparatively, starting from the reflective nostalgia in the prose of Dubravka Ugrešić (The Ministry of Pain), through a global exile which reflects the history of the relationship between European persecutions and America as an unfair homeland, which breaks all identity support in the novels of Aleksandar Hemon (The Nowhere Man; The Lazarus Project), to the intra-Yugoslav, "hereditary" exile in the novels of Goran Vojnović (Chefurs Raus!; Yugoslavia, My Homeland), which fathers left to their sons like a curse of the genus. In the texts mentioned above, the chronotope of exile is dealt with at the level of genre, as the major, supreme chronotope, which includes or opens space to a series of specific local chronotopes, which are fundamental to exile narration. These motifs are also encountered in other genres, but in exile narration they are the bearing pillars of the genre. They are, by their nature, chronotopic because they are realised through the binary spatial-temporal categories of presence and absence, affiliation and non-affiliation, anchoring and nomadism. In this paper, I will look at three such chronotope motifs: 1) the motif of home as a non-place or a place of absence; 2) the motif of other/mirror country and other/”mirror” history; 3) the motif of return and travel (by train), which regularly invokes the stereotypical representation of the place and the past. Chronotop wygnania w powieści postjugosłowiańskiej i granice ojczyzn wyobrażonychChociaż chronotopiczne podejście do analizy powieści problematyzujących wygnanie wydaje się oczywiste, to specyficzne cechy postjugosłowiańskich powieści tego rodzaju wymagają szczególnej interpretacji koncepcji chronotopu, ponieważ literatura postjugosłowiańska jest dodatkowo obciążona kwestią tożsamości. Dla wygnanego pisarza opuszczone przestrzenie lat dziewięćdziesiątych nie znikają jedynie na poziomie metaforycznym, zamieniając się w przestrzeń pamięci (mnemotop), ale faktycznie przestają istnieć jako rzeczywisty byt polityczny. Tym samym, wyobrażone dziedzictwo ponadnarodowe przekształca się w swoistą kontrkulturę, w większości afirmowaną przez pisarzy na wygnaniu. Dlatego też powrót do opuszczonej przestrzeni często jest możliwy jedynie jako powrót do przeszłości. Artykuł omawia literacki motyw wygnania w perspektywie komparatystycznej. Rozpoczyna się od refleksyjnej nostalgii w prozie Dubravki Ugrešić (Ministerstwo bólu). Następnie wiedzie poprzez globalne wygnanie, które odzwierciedla historię związków między europejskimi prześladowaniami a Ameryką jako niesprawiedliwą ojczyzną łamiącą wszelkie tożsamości, w powieściach Aleksandra Hemona (Nowhere Man, The Lazarus Project). Wreszcie, dochodzi do wewnątrzjugosłowiańskiego wygnania „dziedzicznego” w powieściach Gorana Vojnovicia (Chefurs Raus!, Yugoslavia, My Homeland) – wygnania, które ojcowie pozostawili swoim synom niczym przekleństwo rodzaju. W wyżej wymienionych tekstach chronotop wygnania jest rozpatrywany na poziomie gatunku jako główny, nadrzędny chronotop, który zawiera w sobie lub otwiera przestrzeń dla szeregu specyficznych chronotopów lokalnych, fundamentalnych dla narracji wygnańczych. Chociaż podobne motywy występują także w innych gatunkach, to są one filarami w przypadku narracji wygnańczych, z natury chronotopicznych, gdyż realizowanych za pomocą binarnych kategorii czasoprzestrzennych: obecności i nieobecności, przynależności i braku przynależności, zakotwiczenia i nomadyzmu. W tym artykule przyjrzę się trzem takim motywom chronotopu: 1) motywowi domu jako nie-miejsca lub miejsca nieobecności; 2) motywowi innych/lustrzanych krajów i innych/lustrzanych historii; 3) motywowi powrotu i podróży (pociągiem), który regularnie przywołuje stereotypowe przedstawienie miejsca i przeszłości. Kronotop egzila u postjugoslavenskom romanu i granice imaginarnih domovinaPremda je kronotopski pristup romanima egzila gotovo samorazumljiv, određene specifičnosti koje iskazuje postjugoslavenske egzilne naracije prizivaju zasebnu kronotopsku interpretaciju. Prije svega, postjugoslavenska književnost opterećena je dodatnim identitetskim bremenom jer napušteni prostori devedesetih godina za pisca u egzilu ne nestaju na nekoj metaforičkoj razini seleći se u mnemotope, nego se stvarnim raspadom političke cjeline, imaginarna supranacionalna baština transformira u svojevrsnu kontrakulturu, najčešće afirmiranu upravo posredstvom egzilnih pisaca. Stoga i povratak na napušteno mjesto često postaje moguć samo kao povratak u prošlost. U ovom će se radu književna tema egzila pratiti komparativno, počevši od refleksivne nostalgije u prozi Dubravke Ugrešić (Ministarstvo boli), preko globalnog egzila u kojemu se zrcali povijest odnosa europskih progona i Amerike kao maćehinske domovine koja rastače sve identitetske oslonce u romanima Aleksandra Hemona (Čovjek bez prošlosti; Projekat Lazarus), do unutarjugoslavenskog, „naslijeđenog“ egzila u romanima Gorana Vojnovića (Čefuri raus!; Jugoslavija, moja domovina), koje, poput prokletstva roda, očevi ostavljaju sinovima. U navedenim tekstovima o kronotopu egzila govorimo na razini žanra, kao glavnom, nadređenom kronotopu koji uključuje ili otvara prostor nizu specifičnih lokalnih kronotopa ili motiva, ključnih za egzilnu naraciju. Te se motivske jedinice susreću i u drugim žanrovima, no u egzilnoj su naraciji nosivi stupovi žanra. Po svojoj su naravi kronotopični jer se realiziraju kroz binarne prostorno-vremenske kategorije prisutnosti i odsutnosti, pripadanja i nepripadanja, usidrenosti i skitalaštva. U ovom radu osvrnut ću se na tri takva kronotopska motiva: 1. motiv doma kao ne-mjesta ili mjesta odsustva; 2. motiv druge/zrcalne domovine i druge/zrcalne povijesti; 3. motiv povratka i putovanja (vlakom), koje redovito priziva stereotipnu reprezentaciju mjesta i prošlosti.

Papers from the labs of Peter Holland and Jordi Paps investigate patterns of gene presence and absence in plants and animals. Their studies lead to the surprising finding that novel genes do not accumulate with Darwinian gradualism in the phylogeny. The authors describe bursts of innovation with novel gene gains, massive gene losses, and frequent horizontal gene transfer in the history of life.

This book attempts to answer some of the most fundamental questions in ontology. There are many kinds of beings but are there also many kinds of being? The world contains a variety of objects, each of which, let us provisionally assume, exists, but do some objects exist in different ways? Do some objects enjoy more being or existence than other objects? Are there different ways in which one object might enjoy more being than another? Most contemporary metaphysicians would answer “no” to each of these questions. So widespread is this consensus that the questions this book addresses are rarely even raised let alone explicitly answered. But this book carefully examines a wide range of reasons for answering each of these questions with a “yes.” In doing so, it connects these questions with many important metaphysical topics, including substance and accident, time and persistence, the nature of ontological categories, possibility and necessity, presence and absence, persons and value, ground and consequence, and essence and accident. In addition to discussing contemporary problems and theories, this book discusses the ontological views of many important figures in the history of philosophy, including Aquinas, Aristotle, Descartes, Heidegger, Husserl, Kant, Leibniz, Meinong, and many more.
