Flow control by distributed suction behind three-dimensional roughness element on the straight wing model

The paper is devoted to the close investigation of the flow over perforated suction section in the presence of the three-dimensional roughness element. Measurements were conducted over the surface of the straight wing with and without suction. It was shown that distributed suction allows diminishing the intensity of longitudinal structure. Also the boundaries of the effective suction usage were found.

Reshaping posthuman subjectivity: Lu Yang’s representation of virtual bodies in the COVID-19 pandemic

With the impact of the COVID-19 outbreak, much of the world has been experiencing isolation and quarantine. Digital technology, especially the internet, has become the essential method of communication when social distancing measures constrain physical contact. The global health crisis leads to a dynamically increasing reliance on digital equipment contributing to a posthuman world. The article will take Shanghai-based multimedia artist Lu Yang (1984–) as a representative example to explore an alternative posthumanism subjectivity in the context of the COVID-19 pandemic. Built theoretically on Kathrine Hayles and Rosi Braidotti’s posthumanism concepts of virtual bodies, this article will examine how Lu Yang’s work articulates the interactive relationships between humans and the material world to go beyond the conservative corporeality and contribute to a renewal of posthuman subjectivity. In Lu Yang’s recent projects created during the pandemic, such as Doku × The 1975 ‘Playing on My Mind’ (2020) and the live-streamed piece Delusional World (2020), the artist experiments with different strategies to break down social-cultural constraints and transcend established dualisms of gender binaries, life and death, human and non-human. With a close investigation of Lu Yang’s multidisciplinary artistic practices, this article intends to argue how a new subjectivity emerges in contemporary Chinese art and its roles in the current COVID-19 pandemic world.

In Need of a Leader: Bolesław Piasecki’s Charismatic Leadership in the 1930s

This article is part of the special cluster, “National, European, Transnational: Far-right activism in the 20th and 21st centuries”, guest edited by Agnieszka Pasieka. Bolesław Piasecki, the leader of the Polish National Radical Movement (RNR), was one of the influential far-right activists in the 1930s. This article examines his political leadership through the lens of Weberian charismatic authority, enhanced by the analytical Anthony Ammeter’s framework for the analyzing power dynamics of leadership. Through a close investigation of the development of his political career, the article shows—in contrast to much of the existing literature—that Piasecki’s power was forged through triangular interactions between his skills and influential personality, the expectations and needs of his associates, and as a result of a series of events in which he displayed the ability to wield political impact. This approach sheds light on the ways in which political leadership is reliant on a wider network of relationships and shows that Piasecki’s charismatic authority was to a large extent an image constructed by his closest associates. At the same time, it shows parallels and connections between the RNR and other European fascist movements. This approach enables us to define and specify more precisely the nature of the RNR, and dig deep into the complex dynamics lying behind the final failure of the movement and Piasecki’s leadership.

Mitochondrial Phylogenomics of Tenthredinidae (Hymenoptera: Tenthredinoidea) Supports the Monophyly of Megabelesesinae as a Subfamily

Tenthredinidae represents one of the external feeders of the most diverse superfamily, Tenthredinoidea, with diverse host plant utilization. In this study, four complete mitochondrial genomes (mitogenomes), those of Cladiucha punctata, Cladiucha magnoliae, Megabeleses magnoliae, and Megabeleses liriodendrovorax, are newly sequenced and comparatively analyzed with previously reported tenthredinid mitogenomes. The close investigation of mitogenomes and the phylogeny of Tenthredinidae leads us to the following conclusions: The subfamilial relationships and phylogenetic placements within Tenthredinidae are mostly found to be similar to the previously suggested phylogenies. However, the present phylogeny supports the monophyly of Megabelesesinae as a subfamily, with the sister-group placement of Cladiucha and Megabeleses outside of Allantinae. The occurrence of the same type of tRNA rearrangements (MQI and ANS1ERF) in the mitogenomes of Megabelesesinae species and the presence of apomorphic morphological characters also provide robust evidence for this new subfamily. The divergence and diversification times of the subfamilies appear to be directly related to colonization of the flowering plants following the Early Cretaceous. The origin time and diversification patterns of Megabelesesinae were also well matched with the divergence times of their host plants from Magnoliaceae.

God, Suffering, and the Value of Free Will

This book focuses on arguments from suffering against the existence of God and on a variety of issues concerning agency and value that they bring out. The central aim is to show the extent and power of arguments from evil. The book provides a close investigation of an under-defended claim at the heart of the major free-will-based responses to such arguments, namely that free will is sufficiently valuable to serve as the good, or to serve prominently among the goods, that provides a God-justifying reason for permitting evil in our world. Offering a fresh examination of traditional theodicies, it also develops an alternative line the author calls a divine intimacy theodicy. It makes an extended case for rejection of the position of skeptical theism. The book expands upon an argument from evil concerning a traditional doctrine of hell, which reveals a number of interesting issues concerning fault, agency, and blameworthiness. In response to recent work contending that the problem of evil is defanged since God’s baseline attitude toward human beings is indifference, the book defends the essential perfect moral goodness of God. Finally it takes up the question of whether or not it makes sense to live a religious life as an agnostic or as an atheist.

“Exile from Ireland Left Him a Stranger Everywhere“: Representation of Dublin in Selected Louis Macneice’s Poetry and Some of the Stories from James Joyce’s Dubliners”

This paper discusses the representation of Dublin in the selected poetry of Louis MacNeice and some of the stories from James Joyce’s collection Dubliners. A close investigation of the city as a representative of urban space is interlinked with an examination of its role from the perspective of psychogeography. Both techniques are applied to show why and how two Irish authors portray the multi-dimensional decay of life in the city. In order to paint a whole picture of the relation between ‘space’ and ‘human’, I will also review the biographies of MacNeice and Joyce. For MacNeice, who was tormented by the experiences of domestic Belfast, going to the South was a promising escape. Yet, the change of urban setting did not bring him the expected result. MacNeice quickly became aware of the dirty, paralysed face of Dublin. Similarly, the childhood and day-to-day reality of the lower-middle-class profoundly shaped Joyce’s perspective of Dublin and, eventually, prompted him to go into deliberate exile in Europe. In his writings, however, Dublin constitutes the focal point of the structure, becoming an active participant in the events. Therefore, Dublin for MacNeice and Joyce is a place characterized by blandness, powerlessness in the face of foreign influences, and suffering caused by inertia.

Assessing Cyber Challenges of Maritime Navigation

This paper provides a close investigation into the landscape of both cyber threats and actual incidents in the maritime sector, identifying the cyber trends and challenges as they relate to safe navigation and marine shipping. As an important subset of cyber threats that impact many maritime systems, the vulnerabilities of satellite navigation systems, in particular the Global Positioning System (GPS), receive special attention. For this article, a systematic literature review was conducted, complemented by the research and analysis of a specific spoofing event. Analyzing available resources, we might summarize that a shift in mind-set is essential to direct more attention and resources toward cybersecurity as well as the necessity for manufacturers to improve the cybersecurity of their products, as shipping systems currently remain vulnerable to cybercriminals. There is a need for multiple positioning, navigation, and timing (PNT) systems onboard maritime vessels to complement GPS-only navigation. The use of multiple satellite navigation constellations, public as well as private, in combination with the terrestrial components of an enhanced LOng-RAnge Navigation (eLoran) system and ports’ laser-based aid system for berthing and docking should provide the shipping industry with the direly needed increased protection from cyber-attackers for the foreseeable future.

Desire and the other Discourse Represented in "The Great Gatsby"

This paper examines how The Great Gatsby is connected with the Ego discourse and the Other discourse in the meaning of psychoanalysis. This subject demands close investigation as below. First, I compare Gatsby s desire with object a in the meaning of psychoanalysis. Gatsby s love toward Daisy is connected with object a, that is, object a means the price of the loss. Incidentally, the baby is in paradise when he is born. But the paradise between Mother and Baby is lost in the Father’s Name. However, the baby gets object a as the price of loss. Then, human beings can live their life with a desire in their heart. Similarly, Gatsby gets object a when Daisy marries Tom. This helps him to save money, and he becomes a great and rich man. Finally, his desire toward Daisy makes him rich; however, it is just a fantasy. Even though it is just a fantasy, it is essential in a human being s life. Second, I describe the Ego discourse and the Other discourse in the meaning of psychoanalysis. The explanation helps readers to understand this paper easily. For a better understanding, I can say that the Ego discourse and the Other discourse indicate human beings consciousness and unconsciousness. Third, I closely analyze the text in consideration of the Ego discourse and the Other discourse. In the text, the major characters reveal their unconsciousness through normal words. In a broad sense, their unconsciousness is connected with a lost generation and America in the 1920s. Finally, everything in the text is connected with the Ego discourse and the Other discourse. Even though they hide in the text and under the words, they are surely revealed through the slip of the tongue and repetition, etc.

A Mystical Reading of Ḥāfiẓ’s Translation by Robert Bly and Leonard Lewisohn

Robert Bly and Leonard Lewisohn are among the latest translators of Ḥāfiẓ who have selectively translated thirty ghazals of Ḥāfiẓ into English. A close investigation of their translation reveals how they have manipulated the original texts to a great extent which results in having merely a mystical interpretation of Ḥāfiẓ’s multi-layered poems. However, due to the literary form of Ḥāfiẓ’s poetry which is ghazal, it can be in praise of different issues such as nature, youth, beloved, loveliness, etc.; in Bly and Lewisohn’s translation, most of them have been ascribed to divinity. In other words, by means of translation, they have rendered their own worldview along with their personal reading of Ḥāfiẓ’s poetry. The authors argue that Bly and Lewisohn’s translation renders a mystical reading of Ḥāfiẓ’s poetry and presents him as a moral preacher whose poetry is saturated with mysticism and Sufism. Being highly against the American society’s materialism, by introducing Ḥāfiẓ as a mystic and insisting on mystical and spiritual interpretation of his poetry they intend to survive their society from corruption and cater to the moral and spiritual needs of the target culture. Since American literature compared to Persian literature, lacks some repertoire related to mysticism thus Lewisohn and Bly, by means of translation try to provide their culture with a sort of nourishment in order to contribute to the amendment of the society.

Driving Logistics Change in the Pharmaceutical Industry

The pharmaceutical logistics mainly involved the process of packaging, handling, storage, and transportation of drugs, vaccines or pharmaceutical products to the patient that slightly different from the mainstream logistics practice. The nature of the products that need to reach the destination in a fast and safe manner make the pharmaceutical logistics are very challenging and expensive. Despite various issues faced in pharmaceutical logistics, there are still lacking research to address the gap in managing the issue which is the focal point of this study. In this research, a qualitative method was adopted due to the complexity of the process that requires close investigation to understand the real issue. Four (4) Pharmaceutical companies were selected to unveil the theme issue. A strategy framework was developed as a result of the findings and provide an insight to the practitioner on the critical factors that driving on the logistics changes in the Pharmaceutical industry. This study provides a vital finding and serves as an exploratory study for future research.
