Pictographic calendars called waniyetu wówapi or “winter counts” kept by several Great Plains Indian cultures (principally the Sioux or Lakota) preserve a record of events important to these peoples from roughly the seventeenth through the nineteenth centuries. A number of these memorable events include natural phenomena, such as meteor storms, eclipses, and unusual weather and climate. Examination of a selection of the available winter count records and related interpretive writings indicates that the Lakota and other native plains cultures recorded many instances of unusual weather or climate and associated impacts. An analysis of the winter count records in conjunction with observational and proxy climate records and other historical documentation suggests that the winter counts preserve a unique record of some of the most unusual and severe climate events of the early American period and provide valuable insight into the impacts upon people and their perceptions of such events in the ethnographically important region of the Great Plains.

The purpose of the current study was to examine the effect of electronic service quality on fan satisfaction and fan loyalty in the online environment. Selection of three hundred and fifty-six fans of a famous sports club was through random sampling using the club's website. AMOS used structural equation modeling for data analysis. Results provided strong support on the effect of electronic service quality (E-S-QUAL) on fan satisfaction and fan loyalty toward the website of their favorable football teams. Business enterprises have well researched e-service quality and loyalty. However, limited research exists in the sports context. This paper provides valuable insight into the measurement of e-service quality and fan loyalty in the sport and offers a foundation for future marketing research.

Famed for his ground-breaking philological, philosophical, and antiquarian writings, the Brabant humanist Justus Lipsius (1547-1606) was one of the most renowned classical scholars of the sixteenth century. In this volume, Marijke Crab and Ide François bring together the seminal contributions to Lipsius’s life and scholarship by Jeanine De Landtsheer (1954-2021), who came to be known as one of the greatest Lipsius specialists of her generation. In Pursuit of the Muses considers Lipsius from two complementary angles. The first half presents De Landtsheer’s evocative life of the famous humanist, based on her unrivalled knowledge of his correspondence. Originally published in Dutch, it appears here in English translation for the first time. The second half presents a selection of eight articles by De Landtsheer that together chart a way through Lipsius’s scholarship. This twofold approach offers the reader a valuable insight into Lipsius’s life and work, creating an indispensable reference guide not only to Lipsius himself, but also to the wider humanist world of letters.

AbstractNetwork models of brain dynamics provide valuable insight into the healthy functioning of the brain and how this breaks down in disease. A pertinent example is the use of network models to understand seizure generation (ictogenesis) in epilepsy. Recently, computational models have emerged to aid our understanding of seizures and to predict the outcome of surgical perturbations to brain networks. Such approaches provide the opportunity to quantify the effect of removing regions of tissue from brain networks and thereby search for the optimal resection strategy.Here, we use computational models to elucidate how sets of nodes contribute to the ictogenicity of networks. In small networks we fully elucidate the ictogenicity of all possible sets of nodes and demonstrate that the distribution of ictogenicity across sets depends on network topology. However, the full elucidation is a combinatorial problem that becomes intractable for large networks. Therefore, we develop a global optimisation approach to search for minimal sets of nodes that contribute significantly to ictogenesis. We demonstrate the potential applicability of these methods in practice by identifying optimal sets of nodes to resect in networks derived from 20 individuals who underwent resective surgery for epilepsy.

This paper sets out to analyse the hermeneutical process of highlighting at work in Seamus Heaney’s preface to his 1999 retranslation of Beowulf. My analysis takes into account the generic identity of the preface by considering it as a textual subgenre where the translator becomes a metatranslator in order to voice herself out of invisibility, engaging thereby in a (self-reflexive) hermeneutical analysis and ‘justification’ by commenting on the selection of the text to be translated and her own translation choices. The analysis is carried out with the help of two concepts elaborated by Gadamer: situatedness and self-understanding. These concepts will help show how the Northern Irish poet fuses different horizons in the process of his retranslation. In this essay, I also take into account the specificity of retranslation as a particular instance of hermeneutical activity. To do so, I focus on how Heaney introduces his own rendering of Beowulf, and on how he explains the translational choices and processes he opted for in order to render this canonical text into contemporary language. I argue that the closely related notions of situatedness and self-understanding can help bring to the fore how Heaney establishes an intrinsic link between his own retranslation choices on the one hand and, on the other, his cultural identity and poetics. Taking into consideration the hermeneutical dimension of this preface, it will be argued, gives us valuable insight into the retranslation project of Seamus Heaney. It will show that he does not seek to impose on Beowulf a transcendental truth or to fix it in a definite retranslation and interpretation. Instead, situatedness and self-understanding help shed light on how he engages creatively with the epic Anglo-Saxon poem: at issue is both how his retranslation is situated and grounded in his own subjectivity, and indeed with respect to his existential questions, as well as in a wider socio-cultural context.

The electric and thermal properties of the resistor material in an automotive spark plug should be stable during its service lifetime. Containing many elements and many phases, this material has a very complex microstructure. Elemental mapping with an electron microprobe can reveal the distribution of all relevant elements throughout the sample. In this work, it is demonstrated that the charge-up effect, which would distort an electron image and, therefore, is normally to be avoided in an electron imaging work, could be used to advantage to reveal conductive and resistive zones in a sample. Its combination with elemental mapping can provide valuable insight into the underlying conductivity mechanism of the resistor.This work was performed in a CAMECA SX-50 microprobe. The spark plug used in the present report was a commercial product taken from the shelf. It was sectioned to expose the cross section of the resistor. The resistor was known not to contain the precious metal Au as checked on the carbon coated sample. The sample was then stripped of carbon coating and re-coated with Au.

: Oligopeptide transporter 3 (OPT3) proteins are one of the subsets of OPT clade, yet little is known about these transporters. Therefore, homolog OPT3 proteins in several plant species were investigated and characterized using bioinformatical tools. Motif and co-expression analyses showed that OPT3 proteins may be involved in both biotic and abiotic stress responses as well as growth and developmental processes. AtOPT3 usually seemed to take part in Fe homeostasis whereas ZmOPT3 putatively interacted with proteins involved in various biological processes from plant defense system to stress responses. Glutathione (GSH), as a putative alternative chelating agent, was used in the AtOPT3 and ZmOPT3 docking analyses to identify their putative binding residues. The information given in this study will contribute to the understanding of OPT3 proteins’ interactions in various pathways and to the selection of potential ligands for OPT3s.

Background: Plants of the genus Inula are perennial herbs of the family Asteraceae. This genus includes more than 100 species, widely distributed throughout Europe, Africa and Asia including India. Many of them are indicated in traditional medicine, e.g., in Ayurveda. This review explores chemical constituents, medicinal uses and pharmacological actions of Inula species. Methods: Major databases and research and review articles retrieved through Scopus, Web of Science, and Medline were consulted to obtain information on the pharmacological activities of the genus Inula published from 1994 to 2017. Results: Inula species are used either alone or as an important ingredient of various formulations to cure dysfunctions of the cardiovascular system, respiratory system, urinary system, central nervous system and digestive system, and for the treatment of asthma, diabetes, cancers, skin disorders, hepatic disease, fungal and bacterial infections. A range of phytochemicals including alkaloids, essential and volatile oils, flavonoids, terpenes, and lactones has been isolated from herbs of the genus Inula, which might possibly explain traditional uses of these plants. Conclusion: The present review is focused on chemical constituents, medicinal uses and pharmacological actions of Inula species and provides valuable insight into its medicinal potential.

Abstract Background Periventricular nodular heterotopia (PNH) is a malformation of cortical development characterized by nodules of abnormally migrated neurons. The cause of posteriorly placed PNH is not well characterised and we present a case that provides insights into the cause of posterior PNH. Case presentation We report a fetus with extensive posterior PNH in association with biallelic variants in LAMC3. LAMC3 mutations have previously been shown to cause polymicrogyria and pachygyria in the occipital cortex, but not PNH. The occipital location of PNH in our case and the proposed function of LAMC3 in cortical development suggest that the identified LAMC3 variants may be causal of PNH in this fetus. Conclusion We hypothesise that this finding extends the cortical phenotype associated with LAMC3 and provides valuable insight into genetic cause of posterior PNH.
