A New Machine Vision Method for Target Detection and Localization of Malleable Iron Pipes: An Experimental Case
Authors: Pan Zhongqiang , Zhang Dong
Published: December 2022

Malleable iron pipes are widely used in construction, manufacturing, aerospace, and many other fields. Cast malleable iron pipes need to be treated flat to meet the needs of different shapes and sizes. This process is usually completed manually, which is low efficiency and is subject to potential safety risks. To solve this problem, a machine vision method is proposed to detect and localize malleable iron pipes. Point cloud images of malleable iron pipes are obtained by the Random Sample Consensus (RANSAC) algorithm, and precise matching is completed by the Iterative Closest Point (ICP) algorithm to obtain more accurate positions, so as to realize robot grasping. The grasping experiments of malleable iron pipes with the same and different specifications were carried out using a specially designed experimental platform. The results show that malleable iron pipes can be identified effectively and that the corresponding grasping success rate is more than 85 %. The target detection and localization method can obtain the three-dimensional (3D) position of malleable iron pipes to improve grasping efficiency, which provided a certain theoretical basis and guiding significance to improve production efficiency in practice.
Vytýkací povinnost a lhůta k jejímu splnění podle § 1921 ObčZ
Authors: Kolmačka Viktor
Published: December 2022

Předmětem článku je analýza ustanovení § 1921 občanského zákoníku. Podle aktuálního názoru české literatury upravuje první odstavec vedle subjektivní lhůty k vytknutí vady rovněž lhůtu objektivní. Poslední případ přitom má platit pro všechny vady bez rozdílu, a to nejen pro vady skryté, ale též právní. Článek se snaží přesvědčit, že tento závěr se nemůže prosadit. Cestou historické analýzy autor dokládá, že závěry současné literatury jsou důsledkem českého směšování vytýkací povinnosti a lhůty k uplatnění práv z vad, které má kořeny v komunistickém zákonodárství. Důsledkem tohoto přístupu je pak nefunkční právo z vadného plnění a plné hodnotových rozporů. Autor presentuje rovněž vlastní stanovisko k výkladu § 1921 občanského zákoníku, kterým se hodlá těmto nedostatkům vyhnout.

Authors: Somaiya Riddhi , Gonsai Dr. Atul , Tanna Rashmin
Published: December 2022

Transmission of digital content has increases tremendously these days. Privacy and security of the transmitted data has become an important concern in multimedia applications because multimedia data has been an essential part of our lives, from instant messaging applications to social media. For security of the data we use different techniques like cryptography, steganography, and scrambling. Cryptography is one of the main techniques used for information security which includes many forms like digital signatures, authentication etc. and performs system security, confidentiality, data integrity and other functions. This paper works on dual layer security systems using (Elliptic-Curve cryptography) ECC and (Modified Advanced Encryption Standard) MAES called EMAES on Multimedia files (Text, Audio, and Video). Using this approach, unauthorized viewing of the multimedia file can be prevented. Also, this algorithm provides a high level of security and efficiency as compared to existing ones. Comparison of results with other algorithms using parameters like SSIM, FSIM, PSNR and execution time shows that all these parameters are improved 20% or more. The implementation is carried out in MATLAB 2018a.Keywords: Cryptography, RSA, ECC, AES, MAES, IDEA, hybrid algorithm, EMAES.
La competencia ortoépica y su vinculación con las competencias fonológica y ortográfica en la enseñanza de lenguas extranjeras
Authors: Gabarrón Pérez Ángel
Published: December 2022

El Marco Común Europeo de Referencia para las Lenguas (en adelante MCERL) y su actualización, el Volumen Complementario con Nuevos Descriptores, recogen las competencias necesarias para el desarrollo de las destrezas orales y escritas en una lengua extranjera, entre ellas la competencia ortoépica, que relaciona directamente ambas destrezas, quedando definida en el MCERL como la correcta pronunciación de una lengua partiendo de su forma escrita (Consejo de Europa, 2002; p. 115). No se debe hacer ningún análisis de dicha competencia sin establecer una relación coherente con las competencias fonológica y ortográfica. Así pues, la competencia ortoépica podría ser considerada como el resultado de la fusión de ambas competencias en una sola, cuyo dominio permite que el hablante aprendiz sea capaz de descodificar las relaciones entre sonidos y grafías y leer correctamente palabras, oraciones y textos en la lengua meta. El presente artículo pretende analizar dicha relación y el papel de la competencia ortoépica en la enseñanza de lenguas extranjeras. Finalmente, se analizarán las actividades propuestas en el MCERL y las estrategias descritas en el documento para el desarrollo de la misma.

In Defense of Genreblending
Authors: Worth Sarah , McBratnie Sean
Published: December 2022

Readers often only care about one distinction when it comes to things they read—is it fiction or nonfiction?  Did it happen or didn’t it?  Presumably, we make sense of events we believe happened in a different way than we make sense of the ones that we don’t believe.  Deconstructionists often warn us about the hazards that occur with the strict binary thinking we tend to orient ourselves with.  When this binary is blurred, which it often is in many contemporary works of literature, readers become unsettled.  It is our position that genre, and even the more broad categories of fiction and nonfiction, should not be found exclusively as properties internal to the text itself, but rather, the way we make sense of genre is an active process of narrative comprehension.  We will question how the particular binary concerning fiction and nonfiction has sold us short concerning the ways in which we make sense of literary texts, and how much more fluid our notions of genre really could and should be.  We also want to argue that the reduction of the binary of genre merely into fiction and nonfiction is a gross oversimplification of the ways in which we understand both genres themselves, as well as the ways in which we understand both truth and reference.
The Realistic Angel: Realism as Hypothetical Verity
Authors: Buckman Christopher C
Published: December 2022

My main objective in this paper is to formulate a view of pictorial realism I call ‘hypothetical verity’.  It owes much to John Kulvicki but diverges from his view in an important respect: rather than thinking that realistic pictures are true to our conceptions of things, I hold that they are true to what things would be like if they existed.  In addition, I agree with Dominic Lopes that different realisms reflect different aspects of reality, but restate the case without recourse to symbol systems.  Together, the twin principles of hypothetical verity and aspectival absolutism constitute a theory of realism able to account for realistic fictional entities, the problem of revelatory realism and images that teach new information.
On the category of 'the aesthetic'
Authors: James McFee Graham
Published: December 2022

Those contrasting our appreciation of art (as artistic appreciation) with our appreciation of the other occasions when grace, line, elegance, and so on — or their opposites — (as aesthetic appreciation) typically give much fuller accounts of art-based cases, even though it is recognized that many artworks, although not all, could be perceived — that is, mis-perceived — as objects of aesthetic appreciation. Moreover, here, ascriptions of ‘the aesthetic’ typically reflect the claim to positive aesthetic value, rather than the ‘even-handed’ version described in philosophy, giving weight to ugliness. Such a positive conception is well-exemplified in the philosophy of sport, when the attempt to describe a purist conception of sports spectatorship — one devoted to the sport, but without allegiance to any team — presents that purist as “… enjoying sport for its purely positive and aesthetic aspects” (Mumford, 2012 p. 18): that is, the conception of such spectatorship is as directed to the aesthetic. In part, the argument there seems to assume, mistakenly, that what is not appreciated purposively (for sport, in terms of winning and losing) is thereby appreciated aesthetically.

            But here, following a hint from Austin (1979 p. 180), it is urged that the term “aesthetic” is used in such contexts ‘to rule out the suggestion of some or all of its recognized antitheses’: here, in particular, aesthetic interest is contrasted with, and feeds of, purposive interest. In recognizing this is a typical feature of uses of the term “aesthetic” one has an explanation of previous failures to provide an account of aesthetic appreciation at the same level of comprehensiveness as that offered for artistic appreciation: references to the aesthetic are contextualized to the particular antithetical notion being rejected on that occasion. And that was a feature implicitly recognized in the argument identified above, even if then falsely generalized. Yet there is really not just one contrast here: different antithetical terms may be invoked on different occasions. In this sense, aesthetic judgement is context-dependent or occasion-sensitive (see Travis, 2008 esp. pp. 150-160). And that is what grounds the general difficulty for dealing broadly (and briefly) with the category of the aesthetic.
Double Life. Illusion - Disillusion
Authors: Boer Nelle
Published: December 2022

In order to make my life and therefore my art more exciting I often imagine being someone else. While working on art projects, usually for several months, I have lived double lives as art historians and political scientists, but mostly as artists who should have been famous.

To trick my audience into believing the fantasy figures I fabricate are real, I use circumstantial evidence. But with the help of that same audience, the double lives I live become far more interesting. It is their imaginative power that really brings my alter egos to life.

And then Christophe showed me his nicely tailored folders. He still accompanied it with the parlé people nowadays treat young managers during their Powerpoint presentations. When the first folder was opened, though, something changed drastically, in a flash. Suddenly the need for explications dropped away. Without a doubt, these were scribbles straight from the gut, vomited onto the paper when the urge was highest. Without parlé or excuse. Surprising!

That is when we really started talking, Christophe and I.
Blindness and Visual Impairment at an Art Academy
Authors: Mühleis Volkmar
Published: December 2022

The article describes the theoretical and practical questions that rise by including blind and partial sighted students at an art academy. Several examples are presented, like the painter Jonathan Huxley, who studied at the Royal Academy in London or the scluptor Flavio Titolo, who did his art program at the University of the West of England in Bristol. The main theoretical questions go beyond an interpretion of the arts as visual or merely conceptual, and the practical approach includes haptic techniques and sensibilities which might otherwise be none discovered.
Crossing Over: Rauschenberg, Kafka, and the Boundaries of Imagination
Authors: Schmidt Erik Wolfgang
Published: December 2022

How do we make sense of something we don’t recognize? This topic raises an important background question: how do we recognize or come to imaginatively experience the subject that a work of art or fiction presents to us? When philosophers address this topic they often assume the act of experiencing or recognizing something through that work is directly under a reader or viewer’s control. The imaginative act, they tell us, is something that a viewer or reader does with the material presented by a given work. This limits the scope of what we might fail to recognize to cases of ambiguity or under-determination. I suggest that this approach ignores the way in which some works of art or fiction puzzle us not because their content is ambiguous but because they frustrate the imaginative act itself. They do this by making it difficult to navigate the imaginary space a fictional object might occupy. To develop this claim I closely examine several works by Robert Rauschenberg and Franz Kafka and suggest that they undermine the common assumption that the activity of imaginatively engaging a work of fiction is under our control. I conclude by suggesting some implications this lack of control might have for two prominent debates related to the activity of recognizing or experiencing something through an engagement with a work of fiction.
Normativity and Thick Aesthetic Concepts
Authors: Hoffmann Kai-Uwe
Published: December 2022

Thick aesthetic concepts such as ‘gracious’, ‘delicate’ and ‘virtuous’ are, according to the standard theory, characterised as both descriptive and evaluative. In the first part of this paper (I), I examine Sibley’s study of normativity with regard to his version of thick aesthetic concepts. In the second part (II), I concentrate on Zangwill’s recourse to Grice’s theory of implicature and the normative demands this move makes on the process. Finally (III), I develop a sketch that shows which contextual considerations precede the selection process of thick aesthetic concepts and how normative demands govern eventual selections.

The Experimental Art of Noel Harding: At the Intersection of Nature and Technology
Authors: Dapena-Tretter Antonia Jan
Published: December 2022

Until his death in 2016, artist Noel Harding demonstrated continual growth from fairly traditional art objects to large-scale, public sculptures bordering on urban planning. Detailing three major works, this article reveals the artist's conscious move away from art contained within galleries to open-air installations created with environmental stewardship in mind. Projects from Harding's final years affected real change in the community through ongoing audience participation and the actions of many. By uniting the community together with technological and natural forces, Harding's practice ultimately demonstrated that an ecological focus is possible without shunning modernity.
The Truth of the Story and its Variations
Authors: Yazicioglu Sanem
Published: December 2022

Husserl’s investigations on appearances and variations in the constitution of reality has led to the further examinations in what Arendt calls a ‘story’. Arendt argues that we produce our lives as a ‘story’. At the same time, she argues that nobody can be the author of one’s own life story. This intriguing claim implies that autobiography is an impossible task for an individual and that only others are capable of telling one’s own story. The main reason for this claim is that narration is only possible when the narrator has sufficient distance to the narrated life, and one cannot have a sufficient distance from one’s self. In this article, I will argue the following: if distance is a precondition of seeing and narrating, then variations of appearances and the reality that they constitute through different perspectives become a necessary part of seeing and narrating. This argument will emphasize the importance of the plurality of perspectives. Thus it will lead to the further question of whether it makes sense to make a truth claim in any of these perspectives or whether the variations force us to think every truth claim in relation to fiction.
Reading for Opacity and the Cognitive Value of Literary Fiction
Authors: Cools Arthur
Published: December 2022

This article addresses the question of the cognitive value of literary fiction starting from Peter Lamarque’s opacity thesis. My intention is to articulate the cognitive value of literary fiction in accordance with the opacity thesis avoiding the pitfall of formalism to which the opacity thesis risks to be reduced. In a first part, I examine Lamarque’s opacity thesis and discuss the problems of the distinction between opacity and transparency in case of literary fiction. In a second part, I thematize the reader’s interest in reading literary fiction and I analyze it in terms of an interest at a distance. This examination enables me to articulate the cognitive value of literary fiction as intrinsic to the reader’s experience of literary fiction. The main argument for this approach is based upon an observation that I borrow from Roman Ingarden’s reflections on the literary artwork, according to which the reader’s focus on the literary fictional narrative as a whole distinguishes the reading experience of literary fiction. I argue that this focus on the narrative as a whole leads beyond a propositional understanding of the experience of literary fiction and helps us to better understand the reader’s interest in reading literary fiction.
David Wojnarowicz and the Surge of Nuances
Authors: Abramson Paul R , Abramson Tania Love
Published: December 2022

When looking at two paintings, ostensibly by Rembrandt, is there an aesthetic difference in how these paintings are perceived if we know that one of the two paintings is a forgery? Most certainly, declared Nelson Goodman (1976). Knowledge of the difference would modify the aesthetic experience. When looking at Michelangelo’s Christ on the Cross, the result is arguably similar. What we see depends on what we know about Christ’s story. The same might also be said more generally about tragic narratives and their accompanying indicia. Awareness impacts viewers acutely. This is especially evident in curated Holocaust memorials, where the ghastly artifacts, and the unfathomable story lines, are intrinsic to their aesthetic force. This insight however is by no means limited to curated monuments. Learning that an artist, David Wojnarowicz for example, was a victim of inconceivable torment is no less critical to how their artworks are perceived. Our argument, in its totality, is that being informed is preferable to unknowing, and that knowing, however manifested, has the capacity of modifying visual perception.
"The New World": Heideggerian or Humanist Cinema?
Authors: Harrison Britt
Published: December 2022

I offer a new Heideggerian reading of Terrence Malick’s 2005 film The New World, in the style of film-philosophy, alongside a contrasting Cinematic Humanist encounter. I consider if the former is a theory-involving example of philosophy of film, and whether a positive answer to this question entails the latter must be also. I argue that the whilst both engagements with the film use the work of other philosophers as part of their appreciation, Cinematic Humanism nonetheless remains one of many possible ways of doing philosophy of film without theory. Having compared these two methods, I suggest reasons why there is nonetheless a potentially valuable relation to be had between philosophy of film with and philosophy of film without theory. Close attention is paid to the film throughout.
Mourning the Loss of the Ordinary. A Cavellian Reading of Ozu’s "Late Spring"
Authors: Techio Jônadas
Published: December 2022

This paper offers a reading of Yasujiro Ozu’s Late Spring (Banshun, 1949) focusing on its examination of the ordinary: its conditions, its structure, its dynamics, and its fragility. This reading is articulated by juxtaposing some of Stanley Cavell’s main insights concerning modern skepticism and its threat to the ordinary and their corresponding expressions in a series of representative sequences from Ozu’s film. In both cases the notion of mourning plays a central role. I close by establishing one additional parallel between Cavell’s and Late Spring’s interpretations of the ordinary, focusing on the absence of a wedding ceremony at the end of Ozu’s film.
When the silent universe speaks. Testing Camus’ notion of the absurd in the alien encounters of "Contact" and "Arrival"
Authors: Tubali Shai
Published: December 2022

Albert Camus' concept of absurdity - as articulated in his works The Stranger, The Myth of Sisyphus, and The Rebel - outlines a metaphysics of inherent struggle between the human mind that strives for unity and clarity and an inhumanly silent universe. When an absurd mind realises its own inescapable frontiers of knowing, meaning, separation and mortality, Camus argues, it has the Sisyphean choice to embrace such a universe nevertheless, while forever retaining the spirit of revolt that defies it.

In this essay I analyse, side by side, two first-contact films - Robert Zemeckis' Contact (1997) and Denis Villeneuve's Arrival (2016) - to test the validity of Camus' metaphysics in a universe where human estrangement seems to be disrupted by cosmic visitors. The films' thought experiments support Camus' universal vision, indirectly suggesting that even aliens are prone to absurdity. On the other hand, both films offer an approach of intimate communion with the cosmos, in light of which Camus' description of the universe as a stranger seems to demonstrate a limited perspective.
The Flesh is Weak. Empathy and Becoming Human in Jonathan Glazer's "Under the Skin"
Authors: Heber-Percy Colin
Published: December 2022

Jonathan Glazer’s 2013 film Under the Skin offers an unsettling meditation on humanness through the eyes of an alien predator. This essay reflects on Glazer’s film by drawing it into conversation with the later phenomenology of Maurice Merleau-Ponty, with Heidegger, Martin Buber, and with a number of earlier Greek thinkers who together point us towards a more complex and shared definition of ‘contemplation’ or theory. The paper asks: do films watch us as much as we watch films?

Through an exploration of the notion of the mask as a means both of disguise and of disclosure, the paper questions to what extent all human relations are masked, screened. So, Glazer’s film can be viewed as an exercise in re-imagining the role of the screen, turning us from viewers to viewed. This implication of the audience in the film’s scope leads to a concluding focus on empathy as the essential sharedness of human (and therefore of cinematic) experience.
The Vanity of Small Differences
Authors: Liao Shen-yi , Meskin Aaron , Fletcher Jade
Published: December 2022

To what extent are factors that are extrinsic to the artwork relevant to judgements of artistic value? One might approach this question using traditional philosophical methods, but one can also approach it using empirical methods; that is, by doing experimental philosophical aesthetics. This paper provides an example of the latter approach. We report two empirical studies that examine the significance of three sorts of extrinsic factors for judgements of artistic value: the causal-historical factor of contagion, the ontological factor of uniqueness, and the contextual factor of appreciative environment.

We explore the context of appreciation by performing studies in a museum as well as the lab. We found that contagion made a difference in both settings. However, uniqueness only made a difference in the lab setting, but not in the museum. This suggests that the context of appreciation may make a difference to judgements of artistic value. Of broader significance, these studies show the value of experimental philosophical aesthetics and the value of doing in situ empirical research on art.
Aesthetic Debunking and the Transcendental Argument of the Novel
Authors: Weinberg Jonathan , Gjesdal Adam
Published: December 2022

Gilbert Plumer has recently argued in his (2017) that psychologically rich novels offer the reader an opportunity to draw a transcendental inference: what seems to us believable about the psychology of the characters, can be inferred to be actually true about real human psychology. We propose, first, to disambiguate a key term of art in Plumer’s argument, “believable”. Given that disambiguation, the empirically contingent nature of one of Plumer’s premises comes into view. We raise two main lines of empirically-motivated debunking arguments against that premise, drawing particularly upon the psychological literatures about processing fluency, and the illusion of explanatory depth. We then conclude with some further implications for naturalistic approaches to aesthetics, and the relevance of such debunking arguments.
Aesthetic Value and Aesthetic Judgment
Authors: Consoli Gianluca 
Published: December 2022

Contemporary aesthetic naturalism integrates various scientific approaches into the common effort to provide an explanation of the main topics of aesthetics on the basis of empirical methods or in line with available evidence. Although these approaches have recently achieved very relevant empirical and theoretical results, contemporary aesthetic naturalism still does not solve the traditional hard problem of naturalism as such, that is the explanation of value in scientific terms.  Firstly, I analyse the possible responses to this hard problem, showing that aesthetic value, particularly in the version of artistic value, remains outside the scope of current empirical approaches to aesthetics. Then I propose that this apparently strong philosophical limitation can be easily reduced to an ordinary epistemological limitation if aesthetic naturalism accepts to improve the interaction with art criticism, the discipline in the humanities characterised by a privileged access to the historical and social reasons that justify aesthetic judgments.
Grounding Ethics in Aesthetics

In this Editor’s column I suggest a more modern aesthetics, in order to fill in some of the promise the current Special Issue on The Birth of the Discipline has in store for us. I base my suggestion more on Kant and Aristotle, though.

Critical Aesthetics
Authors: Nannini Alessandro
Published: December 2022

In this essay, I discuss Baumgarten’s neglected doctrine of taste. In particular I investigate his definition of taste as the judgment of the senses against the backdrop of the philosophical debate of his day (Muratori, Du Bos), pointing out the biblical and classical sources of the idea of a judging aisthesis. In addition, I analyze the radical change that the definition of taste as the judgment of the senses brings about in the idea of both taste and the judgment of the senses with regard to Wolff. Highlighting the link with the issue of analogon rationis and beauty, I conclude that the concept of taste is at the core of Baumgarten’s new aesthetic project.
In Defence of Moderate Actual Intentionalism
Authors: Hulbert Frederick
Published: December 2022

The extent to which the artist’s intentions are a relevant consideration in the interpretation of art has long been the subject of critical debate.  Initially, I outline the various interpretive positions which have been established, specifically focusing on the debate between hypothetical intentionalism and moderate actual intentionalism.  Then I look at some previous test cases which have, as yet, failed to demonstrate a decisive victory for either side. Finally, I offer two new test cases, one from the field of contemporary visual art and the other from literary theory.  I argue that the former serves to debunk hypothetical intentionalism and the latter lends support to the moderate actual intentionalist position.
Enacting Gifts: Performances on Par with Art Experiences
Authors: Spaid Sue
Published: December 2022

Given the coterie of philosophers focused on everyday aesthetics, it's fascinating that gift reception has heretofore managed to escape their scrutiny. To enact a gift, recipients begin by imagining its use. On this level, gifts serve as a litmus test. In luring us, we're taken out of our normal ways of being to experience a different side of ourselves. Enacting a gift is thus a kind of performance, whose value depends on the donee’s interpretation, just as exhibitions, concerts, staged plays or books are performances of visual art, scores, scripts or texts, whose interpretations demonstrate their aesthetic value. To develop the relationship between enacting gifts and performing artworks, I begin by surveying junctures along the gift-event’s arc: reply, imagination, trust, recognition, transformation and memory. Transformations arising from agonistic gifts strike me as significant because they characterise the way gifts challenge our beliefs, eventually altering our values. That we grow to love gifts, which we originally rejected out of hand, casts doubt on self-knowledge. Enacted gifts handily challenge self-knowledge’s twin features: authority and transparency. As this paper indicates, gift reception helps both to understand ourselves better and to remove the obstacles to what Quassim Cassim calls Substantive Self-Knowledge.

Biema Huo & Zhao gen. nov., a new flower fly genus (Diptera, Syrphidae) from China
Authors: Huo Ke-Ke , Zhao Le , Mengual Ximo , Li Gang , Liu Xin , Zhao Lian-Jun , Chen Zhen-Ning
Published: December 2022

A new flower fly genus (Diptera, Syrphidae), Biema Huo & Zhao gen. nov. from China is described based on two new species: Biema wanglangensis Huo & Zhao gen. et sp. nov. (designated as type-species) and Biema qilianensis Huo & Liu gen. et sp. nov. The new genus can easily be distinguished by the following morphological features: head, mesonotum and scutellum black; postpronotum without pile; metasternum not reduced, posterior margin shallowly concave; katepisternum only with ventral pile patches; alula narrow, as wide as basal width of cell c; male postabdomen conspicuously more swollen than other segments, surstylus and postgonite complex, phallus unsegmented. The results of our Bayesian inference and Maximum Likelihood analysis based on sequences of the Cytochrome c oxidase subunit I (COI) gene, as well as the species delimitation tests, support the separation of Biema Huo & Zhao gen. nov. from its related taxa. Additionally, an identification key to the genera of the tribes Bacchini and Melanostomini occurring in China is provided.
