BackgroundWith the rapid growth of the older adult population worldwide, car accidents involving this population group have become an increasingly serious problem. Cognitive impairment, which is assessed using neuropsychological tests, has been reported as a risk factor for being involved in car accidents; however, it remains unclear whether this risk can be predicted using daily behavior data.ObjectiveThe objective of this study was to investigate whether speech data that can be collected in everyday life can be used to predict the risk of an older driver being involved in a car accident.MethodsAt baseline, we collected (1) speech data during interactions with a voice assistant and (2) cognitive assessment data—neuropsychological tests (Mini-Mental State Examination, revised Wechsler immediate and delayed logical memory, Frontal Assessment Battery, trail making test-parts A and B, and Clock Drawing Test), Geriatric Depression Scale, magnetic resonance imaging, and demographics (age, sex, education)—from older adults. Approximately one-and-a-half years later, we followed up to collect information about their driving experiences (with respect to car accidents) using a questionnaire. We investigated the association between speech data and future accident risk using statistical analysis and machine learning models.ResultsWe found that older drivers (n=60) with accident or near-accident experiences had statistically discernible differences in speech features that suggest cognitive impairment such as reduced speech rate (P=.048) and increased response time (P=.040). Moreover, the model that used speech features could predict future accident or near-accident experiences with 81.7% accuracy, which was 6.7% higher than that using cognitive assessment data, and could achieve up to 88.3% accuracy when the model used both types of data.ConclusionsOur study provides the first empirical results that suggest analysis of speech data recorded during interactions with voice assistants could help predict future accident risk for older drivers by capturing subtle impairments in cognitive function.

The Destruction of Nationalism in Twenty-First Century Canadian Apocalyptic Fiction
Authors: Cormier Matthew 
Published: April 2021

Abstract
This article argues that, since the turn of the twenty-first century, fiction in Canada – whether by English-Canadian, Québécois, or Indigenous writers – has seen a re-emergence in the apocalyptic genre. While apocalyptic fiction also gained critical attention during the twentieth century, this initial wave was tied to disenfranchised, marginalized figures, excluded as failures in their attempts to reach a promised land. As a result, fiction at that time – and perhaps equally so in the divided English-Canadian and Québécois canons – was chiefly a (post)colonial, nationalist project. Yet, apocalyptic fiction in Canada since 2000 has drastically changed. 9/11, rapid technological advancements, a growing climate crisis, the Truth and Reconciliation Commission: these changes have all marked the fictions of Canada in terms of futurities. This article thus examines three novels – English-Canadian novelist Emily St. John Mandel’s Station Eleven (2014), Indigenous writer Thomas King’s The Back of the Turtle (2014), and Québécois author Nicolas Dickner’s Apocalypse for Beginners (2010) – to discuss the ways in which they work to bring about the destruction of nationalism in Canada through the apocalyptic genre and affectivity to envision new futures.
Sea Imagery in Hala Alyan’s Salt Houses
Authors: Awad Yousef 
Published: April 2021

Abstract
This article examines how Palestinian American novelist Hala Alyan employs sea imagery in her debut novel Salt Houses (2017) to reflect her characters’ emotions and thoughts. In particular, this article shows that by examining a number of events in which characters are sitting by the sea or wading into the waters of the sea, the reader is given an insight into these characters’ inner feelings and beliefs and the way they perceive their identities and contextualise their experiences as they move from one city to another. As the novel relates the narratives of four generations of a Palestinian family, sometimes using flashbacks, sea imagery increasingly occupies central positions in these narratives which reveal Alia’s and her descendants’ endeavours to express their opinions through memories and experiences of displacement, exile and estrangement. Although the title of the novel rightly heralds the significance of houses, it is the sea that forcefully emerges as a pivotal component in the narratives that these characters relate in their quests for a homeland that lives in the older generation’s memories and the young people’s imaginations. As Alia’s granddaughter, Manar, visits Palestine in the final chapter of the novel and draws the family tree of the Yacoubs on Jaffa’s beach, including her unborn baby, memories and imaginations merge to assert the right of Palestinians to “belong” to their homeland.
“Catastrophically Romantic”: Radical Inversions of Gilbert and Gubar’s Monstrous Angel in Gillian Flynn’s Gone Girl
Authors: Christensen Ashley E. 
Published: April 2021

Abstract
In their landmark text The Madwoman in the Attic: The Woman Writer and the Nineteen Century Literary Imagination (1970), Sandra Gilbert and Susan Gubar pose a series of hypotheses concerning women-authored fiction in the nineteenth century, identifying two archetypical female figures in patriarchal literary contexts – the Angel in the House, and the Monstrous (Mad)Woman. Gilbert and Gubar echo a Woolf-ian call to action that women writers must destroy both the angel and the monster in their fiction, and many contemporary women authors have answered that call – examining and complicating Gilbert and Gubar’s original dichotomy to reflect contemporary concerns with female violence and feminism. Gillian Flynn’s Gone Girl (2012), and in particular the character of Amy Elliott Dunne, explores modern iterations of the Angel v. Monster dynamic in the guise of the “Cool Girl,” thus revising these stereotypes to fit them in a postmodern socio-historical context. The controversy that surrounds the text, as well as its incredible popularity, indicates that the narrative has struck a chord with readers and critics alike. Both Amy and Nick Dunne represent the Angel and the Monster in their marriage, embodying Flynn’s critical feminist commentary on white, upper-middle class, heterosexual psychopathy.
Mystified Life: Joyce Carol Oates’ Adaptation of Wonderland
Authors: Nagalakshmi Rathinasamy , Tamilmani Kulamangalam Thiagarajan 
Published: April 2021

Abstract
It is apodictic that postmodernism gravitates towards fragmented narratives, apparently “real” diegesis and characters in a chaos-ridden frame. The postmodern novel is a “looking glass” that delineates the vertigo instigated by “reality,” which is an artifice that leads to amending interpretations. The paradox of “fictionalizing the reality” creates heterogeneous reverberations among individuals. There is no preconception, but moments of revelation and realization. The theories of language alleviate the transcription of the intense and inevitable relationship between the text and the reader. The theoretical underpinnings, formulated on the basis of the multiple interpretations emanated by readers, foreground the fact that texts are constituents of our linguistic community, and are diversified with individual and cultural experiences. In this way, the consideration of the text extends beyond its stature of being a mere “object.” Joyce Carol Oates’ Wonderland is a text which abounds in intertextual references in the postmodern context. Oates has taken up the issues of destiny and identity from Lewis Carroll’s Alice’s Adventures in Wonderland, as the thematic source. The protagonist, Jesse, does not enter a world of fantasy; rather, she enters a world that is real, absurd and phantasmagorical. The article purports to analyse Wonderland as “hypertext” and accentuate how the fragments of discourses in it, based on Carroll’s work as the hypotext, have acquired a transpositional change of meaning.
On Grünwlad-Letinkov Fractional Operator with Measurable Order on Continuous-Discrete Time Scale
Authors: Pawłuszewicz Ewa , Koszewnik Andrzej , Burzyński Piotr 
Published: April 2021

Abstract
Considering experimental implementation control laws on digital tools that measurement cards are discharged every time unit one can see that time of simulations is partially continuous and partially discrete. This observation provides the motivation for defining the Grünvald-Letnikov fractional operator with measurable order defined on continuous-discrete time scale. Some properties of this operator are discussed. The simulation analysis of the proposed approach to the Grünwald-Letnikov operator with the measurement functional order is presented.
Hyperspectral Vegetation Indices Calculated by Qgis Using Landsat Tm Image: a Case Study of Northern Iceland
Authors: Lemenkova Polina 
Published: April 2021

Abstract
The vegetation indices (VIs) derived from the hyperspectral reflectance of vegetation are presented in this study for monitoring live green vegetation in the northern ecosystems of Iceland, along the fjords of Eyjafjörđur and the Skagafjörđur. The comparative analysis of the following VIs was performed: the NDVI, RVI, NRVI, TVI, CTVI, TTVI and SAVI. The methodology is based on the raster calculator band in a QGIS. The dataset includes a Landsat TM scene of 2013, UTM Zone 53, WGS84 captured from the GloVis. The computed bands include the NIR and R spectral bands and their combinations according to the algorithms of each of the seven VIs. The hyperspectral reflectance and crop canopy computations were applied to generate various scales of VIs and demonstrated following data range: NDVI: -0.91 to 0.65, RVI: 0.22 to 19.65, NRVI: 0.63 to 0.90, TVI: 0 to 1.12, CTVI: -0.64 to 1.07, TTVI: 0.70 to 1.18 and SAVI: -1.36 to 0.99 (roughly to 1.00). Of these, the RVI, NRVI, TVI and TTVI are adjusted to the positive values while the NDVI, CTVI and SAVI do include the negative diapason in the dataset due to the computing algorithm. The algorithms of the seven VIs are described and visualized in form of maps based on the multispectral remote sensing Landsat TM imagery identifying vegetated areas, their health condition and distribution of green areas against the bare soils, rocks, ocean water, lakes and ice-covered glaciers. The paper contributes both to the technical presentation of the QGIS functionality for the Landsat TM data processing by a raster calculator, and to the regional geographic studies of Iceland and Arctic ecosystems.

Abstract
Genetic improvement of goat breeds in growth and other traits (e.g. milk production) is limited by the demographics of the goat herds, extensive production system and the seemingly long-term nature of improvement through traditional genetics and breeding methods. We studied the genetic morphometry in Nigerian goats and South African Kalahari Red goat breeds. A total of 192 goats belonging to three Nigerian breeds (Red Sokoto (RS), Sahel (SH) and West African Dwarf (WAD)) and one South African Kalahari Red (KR) goat breed were analysed. Animals were classified into four age groups: A group – less than 1 year, B group – between 1 and 2 years, C group – between 2 and 3 years and C group – older than 3 years based on dentition. Analysis of variance, correlation matrix, regression and discriminant analyses were used to evaluate morphological variability. Results revealed that the effect of breed on the measured morphometric traits was significant (P < 0.05). The best prediction equation for body weight (BW) with R2 = 0.84 was obtained when body length (BL), withers height (WH) and chest depth (CD) were included in the model for KR goat. Growth traits were positively correlated with each other with the highest correlation coefficients found between BL and BW (r = 0.877, P < 0.01), WH and BW (r = 0.541, P < 0.01), WH and BW (0.661, P < 0.01) and CD and BW (0.738, P < 0.01) in KR, RS, SH and WAD goats, respectively, which are important for a conscious selection and breeding programme for desired traits. Stepwise discriminant procedure showed that WH, CD and BL were the most discriminating variables to separate KR, RS, SH and WAD goats. In accessing morphological diversity, efforts should be made to include phenotypic variables of at least ≥ 3 in order to minimize ambiguity in classification. Based on the pair-wise distances from the Discriminant function, the study provided informed decision, reference information on goat breeding and conservation strategy.
Pre-semihyperadditive Categories
Authors: Shojaei H. , Ameri R. , Hoskova-Mayerova S. 
Published: April 2021

Abstract
In this paper we extend the notion of classical (pre-)semiadditive category to (pre-)semihyperadditive category. Algebraic hyperstructures are algebraic systems whose objects possessing the hyperoperations or multi-valued operation. We introduce categories in which for objects A and B, the class of all morphisms from A to B denoted by Mor(A, B), admits an algebraic hyperstructures, such as semihypergroup or hypergroup. In this regards we introduce the various types of pre-semihyperadditive categories. Also, we construct some (pre-)semihyperadditive categories by introducing a class of hypermodules named general Krasner hypermodules. Finally, we investigate some properties of these categories.
Joyce’s “Nameless” Hero and Hungarian Jewish Experience
Authors: Goldmann Márta 
Published: April 2021

Abstract
The essay considers the background of James Joyce’s “nameless” hero, Leopold Bloom in Ulysses, from the point of view of his Hungarian Jewish ancestry: his family history in the Western Hungarian town of Szombathely and the Jewish history of his town. It shows how a certain reading of the “Circe” and “Cyclops” episodes of Ulysses reveals them in hindsight as anticipating the nightmarish future of the Holocaust in Eastern Europe. This reading is enabled when taking account of the strong parallels that run between the crisis of progress in human history that Ulysses addresses and the idea of history in Walter Benjamin’s Theses on the Philosophy of History of 1940. 1882, the year of Joyce’s birth, was a turning point, if not actually a new beginning, in the long history of anti-Semitic feelings in Hungary. There was a blood libel case in the town of Tiszaeszlár in Eastern Hungary that year. More widely-known and central to the story of modern anti-Semitism in Central Europe was the holding of the first International Anti-Jewish Congress in Dresden in 1882. A local politician from Szombathely, called Győző Istóczy, is linked to both of these events, Szombathely being the town from which Leopold Bloom’s family originates in Ulysses. By unfolding some of the oblique references hidden in the novel to the history of the Jews in Eastern Europe, and revealing the background of the invented Bloom (Virág) family, the essay shows what tragic fate awaited the real-life Jewish families to which they allude and what would have happened to the Joycean “nameless” hero had he remained in Szombathely.

Abstract
During two feeding trials, the effect of dietary phytogenic mixture on the performance and oxidative stress biomarkers in the liver of broilers reared under thermoneutral conditions (TN) and heat stress (HS) was studied. A number of 60 Cobb 500 chicks/trial were sheltered in environmentally-controlled digestibility cages. On the 14 days of age, the chicks were weighted and assigned to four groups (2 groups/trial with 30 chicks/group). In the first trial, two groups (C-TN and PM-TN) were kept in thermoneutral conditions. In the second trial, other two groups were kept (C-HS and PM-HS) in heat stress (32 ±1 °C). The structure of diets was the same in both experiments. Compared with the control diet (C), the experimental diet (PM) contained the addition of 1% phytogenic mixture (bilberry leaves, peppermint leaves, fennel leaves and sea buckthorn meal). Irrespective of temperature conditions, dietary PM did not affect broiler’s performance. The dietary supplementation of PM delayed protein and lipid oxidation in the liver tissue of broilers in both trials by increasing the hepatic catalase, glutathione and superoxide dismutase activity.

Published: April 2021

Abstract

Study aim: The aim of this study was to determine the optimal angle for maximizing pressure distribution in two types of wheelchairs (tilting and reclining) while using a ROHO cushion, which offers relatively effective pressure distribution.

Material and methods: This study enrolled 28 male and female college students who understood the purpose of the study and agreed to participate. This study aimed to determine the optimal angle for tilting and reclining wheelchairs when using a ROHO cushion at angles of 10°, 20°, and 30° with tilted wheelchairs and 90°, 110°, and 130° with reclining wheelchairs.

Results: The analysis showed that an improved pressure distribution when a tilting wheelchair was used versus a reclining one. A reclining position of ≥110° and a tilt angle of ≥20° led to significant pressure-reducing effects.

Conclusion: The results of this study will help wheelchair users or their guardians to select the optimal wheelchair angle when changing their posture to prevent bedsores. Although no slippage was observed in our study, it is important to remember the proper back position to prevent unnecessary slippage.
