Ray-tracing Simulations and Spectral Models of X-Ray Radiation in Dusty Media
Authors: Ricci Claudio , Paltani Stéphane
Published: March 2023

Dust can play an important role in shaping the X-ray spectra and images of astrophysical sources. In this work we report on the implementation of dust in the ray-tracing platform RefleX. We illustrate the different effects associated with the interaction between X-ray photons and dust grains, such as dust scattering, near-edge X-ray absorption fine structures, and shielding. We show how the cross sections of the photon–gas interaction change depending on the fraction of metals in dust grains (i.e., the dust depletion factor). We compare RefleX simulations to the most widely used absorption model that includes dust and show how X-ray spectra are affected by the presence of dust in the absorbing/reprocessing medium for different geometries. We also show how RefleX can be used to reproduce the dust scattering halos observed in Galactic sources, and we release the first torus X-ray spectral model that considers dust absorption and scattering (RXTorusD), to reproduce the spectra of active galactic nuclei (AGNs). RXTorusD also considers other physical processes that are not included in the most widely used AGN torus models, such as Rayleigh scattering and scattering on molecular gas, which can lead to remarkable differences in the predicted X-ray spectra for the same set of geometrical and physical parameters.

Published: March 2023

We present global 3D radiation magnetohydrodynamic simulations of accretion onto a 6.62 solar-mass black hole, with quasi-steady-state accretion rates reaching 0.016–0.9 times the critical accretion rate, which is defined as the accretion rate for powering the Eddington luminosity, assuming a 10% radiative efficiency, in three different runs. The simulations show no sign of thermal instability over hundreds of thermal timescales at 10 r
g. The energy dissipation occurs close to the mid-plane in the near-critical runs and near the disk surface in the low–accretion rate run. The total radiative luminosity inside ∼20 r
g is about 1%–30% of the Eddington limit, with radiative efficiencies of about 6% and 3%, respectively, in the sub- and near-critical accretion regimes. In both cases, self-consistent turbulence generated by the magnetorotational instability leads to angular momentum transfer, and the disk is supported by magnetic pressure. Outflows from the central low-density funnel, with a terminal velocity of ∼0.1c, are seen only in the near-critical runs. We conclude that these magnetic pressure–dominated disks are thermally stable and thicker than the α disk, and that the effective temperature profiles are much flatter than those in the α disks. The magnetic pressures of these disks are comparable within an order of magnitude to the previous analytical magnetic pressure–dominated disk model.

Alfvén waves (AWs) are ubiquitous in space and astrophysical plasma. Their crucial role in various physical processes has triggered intense research in solar–terrestrial physics. Simulation studies have proposed the generation of AWs along the surface of a cylindrical flux rope, referred to as surface AWs (SAWs); however, the observational verification of this distinct wave has been elusive to date. We report the first in situ observation of SAWs in a flux rope of an interplanetary coronal mass ejection. We apply the Walén test to identify them. We have used Elsässer variables to estimate the characteristics of SAWs. They may be excited by the movement of the flux rope’s footpoints or by instabilities along the boundaries of the plasma magnetic cloud. Here, the change in plasma density or field strength in the surface-aligned magnetic field may trigger SAWs.
Study of terrestrial diatoms in corticolous assemblages from deciduous trees in Central Europe with descriptions of two new Luticola D.G.Mann taxa
Authors: Rybak Mateusz , Czarnota Paweł , Noga Teresa
Published: March 2023

Although many studies have examined the algae associated with various habitats in tree trunks, the diatoms in these environments are still poorly studied. Studies of corticolous algae mainly focus on green algae and cyanobacteria, which are usually immediately visible, while diatoms are mostly overlooked or not reported. During the research, 143 species of diatoms were identified, including two new representatives of the genus Luticola: L. bryophilasp. nov. with relatively large central area and short distal raphe endings and L. confusasp. nov. characterized by the presence of small depressions on central raphe endings. Both are described herein based on light and scanning electron microscopy observations and compared to similar taxa based on literature data. Basic morphological data for almost all the diatom taxa are noted, and their habitat requirements, and photographic documentation are also presented. The present research showed that the occurrence of diatom assemblages on tree trunks is influenced by various factors like host tree species, the area where the host tree grows, and the availability of suitable microhabitats within the trunk. However, the species composition of this assemblages depends mainly on the tree species.
Systematics of Lepidocyrtinus boneti Denis, 1948 (Collembola, Seirinae) reveals a new position for the species within Seirinae
Authors: Godeiro Nerivania Nunes , Bu Yun , Nilsai Areeruk , Deharveng Louis , Cipola Nikolas Gioia
Published: March 2023

Seira boneti Denis, 1948, comb. nov. is examined and redescribed based on syntypes and by a newly discovered Chinese population. Lectotype and paralectotypes were designated, and the type locality of the species has been fixed to Câuda, near Nhatrang, Vietnam. The species was first described in the genus Lepidocyrtinus, but based on morphological and molecular evidence it is here transferred to Seira. For the phylogenetic placement of Seira boneticomb. nov., its mitogenome was included in a dataset comprising 19 species of Seirinae. Maximum Likelihood and Bayesian inferences clustered the species next to Seira sanloemensis Godeiro & Cipola, 2020 from Cambodia, forming a distinct Seira clade from the Old World, confirming the hypothesis of the existence of a different basal lineage of Seirinae in Southern Asia.

Authors: Burrell Sherry A. , Ross Jennifer Gunberg , Keil Kelly M. , Heverly MaryAnn
Published: March 2023

Background:

The coronavirus disease 19 (COVID-19) pandemic challenged nurse educators to develop teaching strategies to engage students in a virtual classroom. This pilot study examined the effect of virtually delivered video-recorded (VDVR) simulation-based experiences (SBEs) with standardized participants on the management of clinical emergencies in patients and families affected by cancer on nursing student learning outcomes.

Method:

A pre- and posttest, one-group, convergent mixed-methods design with questionnaire variant was used. Data were collected before and after SBEs.

Results:

Nineteen senior baccalaureate nursing students participated in this pilot study. The VDVR SBEs resulted in a significant increase in self-perceived competence. Participants had positive perceptions about the use of VDVR SBEs as a teaching strategy. Qualitative themes included realism, critical analysis, and preference for hands-on learning.

Conclusion:

The VDVR SBEs were well-received by prelicensure nursing students as a supplemental teaching strategy to enhance self-perceived competence. Additional research is needed about the effects of VDVR SBEs on learning outcomes.

Authors: Bux Muhammad , Ullah Saleem , Khan Muhammad Bilal , Aloraini Najla
Published: March 2023

For figuring out general variational inequalities, we propose a novel and innovative iterative method. First, we demonstrate that the fixed point formulation and general vaiational inequality are equivalent. The fixed point formulation is used to formulate the explicit and implicit schemes. The general variational inequalities are the basis for the new algorithms. The newly developed algorithm is demonstrated numerically. For figuring out general variational inequalities, these new methods are innovative. Additionally, the convergence analysis is provided under certain favorable conditions.
Bifurcation analysis in a Holling-Tanner predator-prey model with strong Allee effect
Authors: Liu Yingzi , Li Zhong , He Mengxin
Published: March 2023

In this paper, we analyze the bifurcation of a Holling-Tanner predator-prey model with strong Allee effect. We confirm that the degenerate equilibrium of system can be a cusp of codimension 2 or 3. As the values of parameters vary, we show that some bifurcations will appear in system. By calculating the Lyapunov number, the system undergoes a subcritical Hopf bifurcation, supercritical Hopf bifurcation or degenerate Hopf bifurcation. We show that there exists bistable phenomena and two limit cycles. By verifying the transversality condition, we also prove that the system undergoes a Bogdanov-Takens bifurcation of codimension 2 or 3. The main conclusions of this paper complement and improve the previous paper [30]. Moreover, numerical simulations are given to verify the theoretical results.

Dynamic Body Bias
Authors: Niranjan Vandana
Published: March 2023

The demand for portable device applications has grown immensely. For such applications, low voltage and low power operation is an essential prerequisite to prevent overheating and ensure reliable functioning. Low voltage operation curtails the total number, weight, and dimensions of batteries, and low power consumption extends battery life. The shrinking size of MOS transistors in CMOS processes necessitates the use of lower supply voltages. Since the threshold voltage of MOS transistor is not diminished at the same rate as the power supply voltage, analog designers face problems due to shrinking voltage headroom. One of the findings that can overcome the issues introduced by comparably high threshold voltages is based on the enactment of body bias approach. In such a solution, a relatively small potential is applied at body terminal of a MOS transistor to adjust its threshold voltage. This chapter discussed that body bias approach is an attractive opportunity for utilizing the body effect positively to improve the performance of low voltage-integrated circuits.

Published: March 2023

Nearly all application fields are paying increased attention to the internet of things (IoT). Nearly 20 billion devices are now linked to the internet. With several applications ranging from smart buildings and smart cities to smart devices, IoT has progressed over the last few decades. As a result, the quantity of sensors, sensor nodes, and gateways has increased, making these battery-powered devices power-hungry. It will be a laborious operation to change the battery in remote monitoring applications for these smart sensors or nodes. By gathering RF energy from the environment and converting it to DC power, RF energy harvesting is a cost-effective method of extending the lifespan of wireless sensor networks (WSNs). A brand-new, IoT-based smart universal charger is suggested in this chapter for charging multichemistry batteries. The suggested charger has an advantage over traditional chargers since it can charge both already installed batteries and any future batteries.

Published: March 2023

Any internet of things (IOT) deployment must have connectivity; this is accomplished by WSNs (wireless sensor networks). A few factors need to be taken into account when choosing a wireless technology for an IoT device: the maximum throughput, the distance range, the availability in the deployment zone, as well as the power consumption. The aim of this research is to maximize the lifetime of the nodes of WSN and to reduce the energy consumption. The system is also focused on managing WSN nodes with huge residual energy, small routing distance, and with maximum number of neighbors. This system makes use of LEACH protocol, and this protocol is hierarchical clustering protocol and also energy efficient. The cluster is constructed in such a way that average dissipation of energy in each node is minimized, and speed of the network is increased. To connect sensor networks with gateways and transfer data from these sensor networks, other technologies such Sub-1 GHz are Zigbee can also be employed.

In search for new cancer treatments, the anti-tumor effects of cannabinoids are under investigation. This study systematically reviews the experimental and clinical evidence for benefits of cannabinoids in cancer. Literature search was conducted through PubMed, EBSCO Host, and ProQuest electronic databases. The text words “medical marijuana,” “cannabis,” “cannabinoids,” “cannabidiol (CBD),” and “Δ9-Tetrahydrocannabinol (THC),” with the Boolean operator “AND” “cancer” either “brain,” “lung,” “breast,” “prostate,” “colorectal,” or “pancreatic” were used to identify studies on anti-tumor effects of cannabinoids. Treatment with cannabinoids decreased cell proliferation, tumor size, angiogenesis, adhesion, migration, and metastasis, and promoted cell cycle arrest, apoptosis, and autophagy in tumor cells and xenograft models and overall survival in cancer patients. There is strong experimental evidence for anti-tumor effects of cannabinoids. Clinical trials are warranted, and further experimental studies are needed to elucidate the pharmacologic potential for cannabinoids in oncology.
Role of Cannabinoids in the Regulation of Amyotrophic Lateral Sclerosis (ALS)
Authors: Muthuramalingam Akila , Pandurangan Ashok Kumar , Banerjee Subhamoy
Published: March 2023

Amyotrophic lateral sclerosis (ALS) is a degenerative disease that manifests in older adults as a result of death of motor neurons. Incidence is 60-80% sporadic and 10-20% familial. The most common mutations are SOD-1, TARDBP, and FUS. Abnormal protein aggregation, inflammation, and dysfunction of RNA are seen. Tremors, dyslexia, and inability to walk progress to death. No cure is available to date. Medical cannabis may delay ALS progression by its neuroprotective, antioxidant, and anti-inflammatory properties. This chapter examines the effects of cannabinoids in ALS and discusses their mechanisms of action. Several psychoactive compounds like THC delay the progression and increase survival rates in a few animal models including the G93A mouse model. The binding of THC to CB receptors, CB1 and CB2, can reduce glutamate secretion thereby reducing excitotoxicity. Targetting CB1 and CB2 receptors with THC agonists could inhibit inflammatory responses, prevent oxidative damage, and reduce microglial activation. This study reviews the evidence for therapeutic effects of cannabinoids in ALS.

Published: March 2023

Cannabis has been used by humans both for recreational and therapeutic purposes since ancient times. Among 113 different cannabinoids from Cannabis, D9-trans-tetrahydrocannabinol (D9THCs) is primarily hallucinogenic and cannabidiol (CBD) is therapeutic. The growing interest in therapeutic uses of Cannabis has created interest in several other plants which are non-cannabinoid and have secondary metabolites similar to CBD known as cannabimimetic plants. The cannabimimetic plants are currently gaining attention and can be the potential alternative to Cannabis because of certain secondary metabolites with a similar mechanism of action binding with cannabinoid receptors. For example, phytoextracts from liverworts Radula marginata, amorfrutin in Amorpha fruticose and several Rhododendron species have been reported to have cannabinoid-like properties. This chapter is providing a complete review of cannabimimetic plants focusing on botanical, biochemical, and potential therapeutic aspects.
Self-Directed Learning Is a Social Activity (and Not a Generalized Skill)
Authors: Porcaro David S.
Published: March 2023

The perspective of self-directed and self-regulated learning as a generalized skill discounts the fact that a major driver of self-direction is an individual's motives centered on communities of practice. Effective design of learning experiences that foster agency, self-direction, and curiosity requires a clearer understanding of this relationship. Activity theory provides a helpful model for explaining the internal and external interactions of learning, both individually and within a community. Without this perspective, educators too often blame learners as failing to have self-regulation when in reality these learners are working under a different set of goals, roles, rules, or tools than those of the learning designer. Using this framework, this theoretical overview will demonstrate ways an immersive adult technology training academy helps support novices striving to enter technology-related careers, as they develop the identity, skills, and self-regulation of coding, data, and design professions.

A Radical Image Steganography Method Predicated on Intensity and Edge Detection
Authors: Sarkar Abhijit , Samanta Sabyasachi
Published: March 2023

The internet has grown to be widely used by billions of individuals in our digital age. The internet is required for a variety of platforms, online apps, and standalone applications. Numerous methods, including cryptography, encryption/decryption, and data concealment algorithms, are developed for this goal. However, the employment of these methods was not very secure, making it simple for hackers to get the secret message. A new method called “steganography” was developed to offer the highest level of protection for sensitive data. Steganography's primary goal is to conceal the presence of concealed messages. Additionally, it seeks out concealed messages using factors like the kind of embedding method, the message's length, its content, or the carrier's secret key. At this point in the chapter, a single bit of data has been embedded into edge-based pixel positions with arbitrary bit positions. The authors have compared their method to three standard edge detection algorithms for a more comprehensive assessment. Different statistical measures also have been made for the uniqueness of the technique.

Authors: Musa Shuaibu
Published: March 2023

Traditional and cultural practices related to newborn care have been passed down through generations in various cultures worldwide, often with the belief that they are effective in improving the health and well-being of newborns. These practices can differ significantly between cultures. The aim of this study was to assess the traditional and cultural newborn care practices in the Dakace and Tsibiri communities of Nigeria, and to identify potential opportunities for the integration of these practices into modern healthcare approaches. An ethnographic study was conducted in the Dakace and Tsibiri communities of Nigeria, which involved observing 54 deliveries and traditional rituals surrounding newborn care through participant observation. A total of 30 participants, including traditional birth attendants, community health workers, traditional leaders, and mothers who had given birth within the past year, were included in the study, and participated in in-depth interviews and focus group discussions. The main themes that emerged from the data included the provision of warmth, nutrition, cord care, and traditional medication. In these communities, there is a strong emphasis on keeping newborns warm and providing proper nutrition, including breastfeeding and the use of traditional remedies. Cord care is also considered important, with the umbilical cord typically cut with a new razor blade and the stump treated with hot compresses and oil massages. Traditional and cultural beliefs also influence the use of traditional medication, including the use of traditional remedies to address common pregnancy-related health issues and the importance of proper nutrition during pregnancy. The study also identified the important role of fathers and other male family members in childbirth preparation. The findings of this study provide valuable insights into the traditional and cultural practices of newborn care in the Dakace and Tsibiri communities of Nigeria and identify potential opportunities for integrating these practices into modern healthcare approaches in a way that is safe and effective for the mother and child. These findings may be of interest to healthcare professionals, researchers, and policy makers working in maternal and child health, as well as to members of the Dakace and Tsibiri communities.
Giant basal cell carcinoma of the scalp: rotation advancement flap as successful dermatosurgical approach
Authors: Tchernev Georgi , Kordeva Simona , Lozev Ilia
Published: March 2023

Giant keratinocyte tumors, in particular basal cell carcinomas of the scalp area, are a serious challenge for dermatosurgeons, oncologists, maxillofacial and reconstructive surgeons. The scalp area is limited in terms of skin mobility, and its elasticity decreases with age. The size of the tumors in this area and the degree of infiltration of the underlying tissues are important for the therapeutic choice - from surgical removal, waiting for granulationsto form and placing a split skin mesh graft (at a later stage), to performing complex rotational/transpositional or progressive flaps. Achieving an optimal aesthetic result is often the result of interventions carried out or based on the decisions of multidisciplinary teams. Alternatives such as radiotherapy and targeted therapy with vismodegib, for example, could be administered both preoperatively and postoperatively or as first-line therapy depending on tumor board decisions. We present a 69-year-old female patient with histopathologically proven preoperative giant basal cell carcinoma of the scalp that did not involve the tabula externa. Surgical treatment under general anesthesia was planned. A preoperative ultrasound was performed due to the repositioned area and the preservation of the feeding arteries. During the operation, the resection lines were in close proximity, but did not affect the arterial vessels. After applying the rotational advancement flap technique, under general anesthesia, an optimal cosmetic effect was achieved.
A sudden right-to-left shunt: the importance of evaluating patent foramen ovale during exercise
Authors: Crispino Simone Pasquale , Segreti Andrea , La Porta Ylenia , Liporace Paola , Carpenito Myriam , Cammalleri Valeria , Grigioni Francesco
Published: March 2023

A 55-year-old male affected by heart failure with reduced ejection fraction and a history of a transient cerebrovascular accident was accepted to the Cardiology Department for worsening dyspnoea. A cardiopulmonary exercise testing was performed after therapy optimization to further evaluate exercise intolerance. A rapid increase in VE/VCO2 slope, PETO2, and RER, with a concomitant decrease in PETCO2 and SpO2, were observed during the test. These findings indicate exercise-induced pulmonary hypertension leading to a right-to-left shunt. Subsequent echocardiography with a bubble test unveiled the presence of an unknown patent foramen ovale. It is, therefore, necessary to exclude a right-to-left shunt by cardiopulmonary exercise testing, particularly in patients predisposed to develop pulmonary hypertension during exercise. Indeed, this eventuality might potentially provoke severe cardiovascular embolisms. However, the patent foramen ovale closure in patients with heart failure with reduced ejection fraction is still debated because of its potential hemodynamic worsening.
Promoting Prospective Mathematics Teachers' Understanding of Derivative across Different Real-life Contexts
Authors: Kertil Mahmut , Gülbağcı Dede Hande
Published: March 2023

This study investigates prospective secondary school mathematics teachers' developing conceptions about the meaning of derivative (as rate of change) while working on a series of tasks involving different non-motion real-life contexts. The study was conducted by employing a case study method. The participants of the study were 25 prospective secondary school mathematics teachers enrolled in the mathematics teaching methods course. A series of contextual tasks involving different real-life situations about derivative was designed and implemented in the form of problem-based learning as a regular part of the course. Pre and post questionnaires, written group solutions to the tasks, individual reflection papers, and video-recorded online classroom discussions were the data sources. A constant comparative analysis method was employed in analysing the data. The results showed that prospective teachers have difficulties in interpreting the meaning of derivative in different real-life contexts. While they were frequently using â€œamount of changeâ€ and â€œslopeâ€ interpretations, they started to use â€œrate of changeâ€ interpretation. However, the classroom discussions showed that most of the prospective teachers were using the â€œrate of changeâ€ expression as a memorized term without engaging in its contextual meaning. We made some inferences about the teaching and learning of derivative and also the professional development needs for teachers.
College Developmental Mathematics Students' Understanding of Fraction Operations

Students enrolled in post-secondary developmental mathematics courses hold mathematical misunderstandings that begin prior to their college careers. Specifically, these students struggle with the conceptual understanding related to fractions, ratios, and proportions. The Common Core State Standards in Mathematics outline standards for K-12 mathematics education. Standards for fractions, ratios, and proportions are found in grades 3-7. Through a research instrument, collegiate developmental mathematics students were investigated regarding their understanding of these standards. It was determined that participants showed evidence of limited knowledge of the examined areas involving fractions, ratios, and proportions. Because it seems that this lack of understanding is rooted early in their educational careers, and is continued throughout students' academic careers, it is hoped that this work can be a starting point for future work in this field that may apply to investigating ways to bridge these gaps in mathematical understanding.
The Spiral Compressor - An Innovative Air Conditioning Compressor for the New Generation Automobiles
Authors: Hiraga Masaharu
Published: March 2023

SANDEN CORPORATION (named SANKYO ELECTRIC CO., LTD. prior to September 1982) developed a new automobile air conditioning compressor, the "TR" type, based upon the spiral machine principle.

Two spiral components have 2.8 turn involute spiral walls projected from discs. Both spiral components are housed in a cylindrical casing, with one in a fixed position and the other interleaved with the former at an angular relationship of 180°. The free moving component is driven by a crankshaft in an orbiting motion. The orbiting motion of the free moving component provides a continuous compression process in two pairs of compression pockets.

The "TR" compressor has several unique features in its physical and mechanical design: (1) Specifically disposed and shaped spiral components to maximize the displacement within a small diameter casing, (2) A compliant crank mechanism utilizing the swing motion of an eccentric bush, (3) A perfect dynamic balancing mechanism with minimized radial forces, and (4) An anti-rotation coupling mechanism with a function of the orbiting thrust bearing.

These basic features result in a number of advantages in application which are of interest to today's automotive design engineers:

(a)

High refrigeration capacity from a compact, lightweight package achieved by combining the super high speed capability (up to 13,000 rpm) and a high volumetric efficiency (75% to 85%).

(b)

Extremely smooth operation with low torque requirement and inherently low torque variation.

(c)

Weight reduction of the compressor and its mounting means.

(d)

High performance, comfortability and drivability combined with low N.V.H. (Noise, Vibration, and Harshness) characteristics.
Heidegger in Hisamatsu

Članek prinaša vnovičen razmislek o nenavadni vzajemnosti evropske in japonske misli, ki se je zgodila Heideggrovi fenomenologiji in japonski, kjotski budistični misli Shin’ichija Hisamatsuja. Odgovor na vprašanje, zakaj je Heidegger vzbudil takšno zanimanje pri japonskem mislecu, je tudi odgovor na vprašanje, kaj je tisto, s čimer je Heidegger tako nenavadno izstopil iz evropske filozofske tradicije. Če drži, da je japonski misli odpiranje za evropsko filozofijo pomagalo, da doseže svoje lastno bistvo, vsekakor drži tudi obratno: tisto izmuzljivo nenavadno budistične misli (vsaj) evropskim fenomenologom pomaga jasneje razbrati Heideggrovo resnico biti. Fenomenologija resnice biti zgolj v okviru evropske filozofije se lahko izgublja v repetitivno negativnih opredelitvah, ko mora vedno znova dokazovati in kazati, da osredotočenost na zgolj bivajoče ne zadošča in da bit ni nikoli isto kot bivajoče. S to negativno potjo pa ostaja v primežu primata bivajočega. Zato bi lahko dejali, da Hisamatsu s svojo mislijo o niču Heideggrovo resnico biti sprošča v njenem bistvu kot njenem zjasnjenju mimo odpravljanja, ukinjanja, zanikanja bivajočega. Heideggru je bilo jasno, da evropska in japonska misel nikoli ne bosta stopili druga drugi za hrbet v čisto očitnost resnice drugega. Še več – da je taka ambicija v osnovi zgrešena. Drugi je tisti, ki naj ostane drugi ravno zato, da me razkriva v moji lastni enkratnosti. Enigmatičnost drugega je tista, ki pomaga k večji, boljši razjasnitvi mene samega. Zahod in Vzhod v tem oziru – to je tudi osnovna ambicija pričujočega članka – ne prinašata vzajemnosti kot istosti, pač pa vzajemno drugost, ki vzpodbuja rast lastnega. Če torej evropska pot pelje od bivajočega k biti, je – po trkih z japonskim polnim ničem – evropska pot pravzaprav še toliko bolj pot od biti k bivajočemu.
Processing of Centre-embedded and Right-branching Relative Clauses in Slovenian
Authors: Marjanovič Katarina , Manouilidou Christina
Published: March 2023

The current consensus in the literature of processing of relative clauses states that centre-embedded relative clauses introduce a heavy computational load. While this is well-established, most evidence for it comes from English, while the empirical evidence from many other languages is still lacking. Here, we try to fill this gap by researching the differences in the processing times of centre-embedded and right-branching relative clauses in Slovenian. We report results from a sentence-picture matching task, in which we observe longer reaction times and lower accuracy when the participants are dealing with centre-embedded relative clauses, compared to right-branching ones. This result provides important evidence in a so far largely under-investigated language, contributing to the theoretical claim that the difficulties observed in the processing of centre-embedded relative clauses are language-independent.
„Zadanie tłumacza” w dobie antropocenu. Dzisiejsza rola przekładu w świetle ekopoetyki i realizmu spekulatywnego

“The Task of the Translator” in the Anthropocene. Today’s Role of Translation in the Light of Ecopoetics and Speculative Realism

According to the 2014 UCL report on communicating climate change, a new social contract is necessary to save the biosphere, challenging us not only to provide commentary on scientific data, but also to rethink the categories framing the relationship between humanity and the natural environment. The former is related to translation insofar as it regards the development of accounts that convey conclusions from natural sciences in rhetorically impactful ways. The latter defines “the task of the translator” in the Anthropocene – to draw from Walter Benjamin – as the effort to develop, in processes of translation, more self-conscious metaphors of inhabiting the Earth. A special role would be played in this area by literature, especially the kind that foregrounds environmentally-aware linguistic invention capable of overcoming the persisting dualism of nature and culture. The aim of this article is to sketch a theoretical framework for such an understanding of translation on the basis of ground-breaking research in the fields of translation studies (Michael Cronin, Kobus Marais), ecopoetics (Julia Fiedorczuk, Gerardo Beltrán), and philosophical criticisms of anthropocentricism formulated within the post-humanities and speculative realism (Bruno Latour, Catherine Malabou). To illustrate these claims, the article invokes poems by Alice Oswald, Sinéad Morrissey (translated by Magda Heydel) and Forrest Gander (translated by Julia Fiedorczuk). These translators are tasked with reconstructing – to borrow Benjamin’s idea – a “pure language” understood here as an expressive absolute that defies anthropocentric limitations. Accommodation of various languages, including non-human ones (as biosemiotics suggests), could thus streamline the development of a new social contract or “constitution” (as Latour terms it) that would redefine (or re-translate) the social and the natural.
Odżytek – zapoznany termin polskich nauk o kulturze

Odżytek – A Forgotten Term of Polish Cultural Sciences

Edward Burnett Tylor’s (1832–1917) Primitive Culture: Researches into the Development of Mythology, Philosophy, Religion, Art, and Custom, one of the most important books in the history of anthropology, was published in two volumes in 1871. The Polish translation, published between 1896 and 1898 (t. 1–2) was based on the third, revised English version (vol. 1–2: 1891). It was made by Zofia Antonina Kowerska (1871–1946) and published under the title Cywilizacja pierwotna; badania rozwoju mitologji, filozofji, wiary, mowy, sztuki i zwyczajów. Jan Aleksander Karłowicz (1836–1903) was responsible for the realisation of the project.

Actualising in the linguistic and cultural context, Tylor’s terminology became one of the fundaments of cultural theory reflection. In this paper I explore the problem of translation of chosen terms introduced by Tylor, namely survival and revival. The former (Polish: przeżytek) proved crucial for the evolutionistic thought and it is directly associated with it. As for the latter, however, modern Polish readers of Tylor’s writings, as well as the authors of textbooks on the history of cultural sciences, fail to notice its terminological character. On the basis of a comparative analysis of excerpts from Primitive Culture and Cywilizacja pierwotna, I argue that the word revival has only been terminologized on the English academic ground (being complementary to the term survival), while in Polish tradition/Polish ground it has failed to become part of specialist language and has ultimately fallen into oblivion.
