June 1989 : Jan Józef Lipski and the foundations of non-secular democracy
No full textTekst jest analizą strategii politycznej Jana Józefa Lipskiego w czerwcowych wyborach 1989 roku. Sięgając do literatury i materiałów archiwalnych autor pokazuje, jak Lipski - zdeklarowany socjalista i agnostyk - szukał poparcia społecznego manifestując swoje przywiązanie do Kościoła i tzw. wartości chrześcijańskich oraz jako przeciwnik aborcji. Strategię Lipskiego autor analizuje jako przykład kształtowania się dyskursu hegemonicznego polskiej demokracji nieświeckiej dowodząc, że "kompromis aborcyjny" został zawarty już w Czerwcu ’89This text analyzes Jan Józef Lipski’s political strategy in the June 1989 elections. Drawing on literature and archival materials, the author shows how Lipski - a declared socialist and agnostic - sought public support and manifested his commitment to the Church and Christian values, and that he opposed abortion. The author examines Lipski’s strategy as an example of the formation of the hegemonic discourse of Polish non-secular democracy, proving that the "abortion compromise" had already been concluded in June ’89. Keywords: abortion, democracy, transformation, socialism, Church, June ’89, discourse, censorshi
Bachmann – Lipski – Opel. Resztki języka
No full textThe article presents some new research findings concerning Leo Lipski’s life in view of previously unexplored archival materials. The author argues that German was the writer’s mother tongue and analyzes its significance in his literary works. Moreover, the article reconstructs Lipski’s links with the German-speaking world and demonstrates that it was Adolf Opel’s initiative to have Piotruś [Little Peter] translated into German. Furthermore, it was Opel who encouraged his partner, Ingeborg Bachmann, to take interest in Lipski’s works. On the basis of the latest research findings, the author also briefly discusses a set of Lipski’s surviving letters sent to the Austrian writer.Artykuł prezentuje szereg ustaleń badawczych na temat biografii Leo Lipskiego, poczynionych na podstawie kwerend niebadanych dotąd materiałów archiwalnych. Wskazuje na niemiecki jako język macierzysty pisarza, przyglądając się tekstowym funkcjonalizacjom tego problemu. Jednocześnie artykuł rekonstruuje związki Lipskiego z niemieckojęzycznym kręgiem kulturowym, udowadniając, że osobą, która bezpośrednio przyczyniła się do powstania niemieckiego przekładu Piotrusia, był Adolf Opel. To właśnie też Opel zainteresował pisarstwem Lipskiego swoją partnerkę, Ingeborg Bachmann. Powołując się na ostatnie odkrycia archiwalne, tekst pokrótce omawia zachowany zbiór listów, jakie Lipski wysłał do austriackiej pisarki

Defoe's Foes:The Author as Character
No full textThe most famous fictional Defoe features in J. M. Coetzee’s Foe (1986), in which he conjures Robinson Crusoe out of a memoir by a “true” castaway. Harrumphing across the country alongside the modern-day narrator of Stuart Campbell’s Daniel Defoe’s Railway Journey (2017), a surreal iteration quite literally leaps out of the pages of a Penguin Classics edition of his real-life counterpart’s travel writing. Setting aside a long tradition of neo-Georgian novels in which Defoe cameos as a seventeenth-century spy, a Defoe-as-character only for all intents and purposes, this chapter attends to two complex cases in the genre of author fictions: Coetzee’s Foe and Campbell’s Defoe
Conceptualization of God in the Utterances of Patients with Paranoid Schizophrenia – Contribution to the Study of Semantics
No full textArtykuł jest wynikiem prowadzonych przez autora badań lingwistycznych w grupie osób z zaburzeniami psychicznymi, a przede wszystkim ze schizofrenią. Celem badań było dotarcie, zanalizowanie i opisanie tego, jak osoby chorujące na schizofrenię myślą i mówią o Bogu. Jest rozwinięciem dwu uprzednio opublikowanych artykułów (Lipski, 2011; 2013). Badania miały charakter eksperymentalny i zostały przeprowadzone z wykorzystaniem autorskiego narzędzia – kwestionariusza, zgodnie z którym prowadzony był wywiad z pacjentami. Celem pracy jest przedstawienie sposobu postrzegania Boga w dwu grupach chorych na schizofrenię, tj. grupie pacjentów z pierwszym epizodem psychotycznym (PEP) oraz pacjentów chorujących na schizofrenię przewlekle (PS). Pacjenci z drugiej grupy w odróżnieniu od tych z PEP prezentowali silne zaburzenia schizofatyczne.
Problem badawczy założony w pracy dotyczy postrzegania wycinka rzeczywistości z systemu wartości osób chorych. Autor tekstu wychodzi poza zjawiska stricte językowe, które są obszarem badań językoznawczych i logopedii, do problemów związanych z aksjologią i poznaniem u osób chorych. Przygląda się systemowi wartości osób chorych na schizofrenię na różnym etapie rozwoju choroby oraz opiniom chorych na temat tegoż systemu.The article is the result of linguistic research conducted by the author on a group of people with mental disorders, especially schizophrenia. The research aimed to reach, analyse and describe how people with schizophrenia think and speak about the divine. It further develops two previously published articles (Lipski, 2011; 2013). The experimental research was conducted using a proprietary tool, a questionnaire, according to which patients were interviewed. This study aims to present the perception of God in two groups of patients with schizophrenia, i.e. a group of patients with a first psychotic episode (PEP) and patients with chronic schizophrenia (PS). Patients in the second group, in contrast to those in PEP, presented a severe schizophrenic disorder.
The research problem assumed in the paper concerns the perception of a slice of reality from the patients’ value system. The author of the text goes beyond strictly linguistic phenomena, which is the area of linguistics and speech therapy research, to problems related to the axiology and cognition of affected people. The researcher examines the value system of people with schizophrenia at different stages of the development of the illness and the patients’ opinions about this system
Palenquero and Spanish in contact: exploring the interface Contact language library ;, v. 56./ John M. Lipski.
No full textIncludes bibliographical references and index."Bilingual speakers are normally aware of what language they are speaking or hearing; there is, however, no widely accepted consensus on the degree of lexical and morphosyntactic similarity that defines the psycholinguistic threshold of distinct languages. This book focuses on the Afro-Colombian creole language Palenquero, spoken in bilingual contact with its historical lexifier, Spanish. Although sharing largely cognate lexicons, the languages are in general not mutually intelligible. For example, Palenquero exhibits no adjective-noun or verb-subject agreement, uses pre-verbal tense-mood-aspect particles, and exhibits unbounded clause-final negation. The present study represents a first attempt at mapping the psycholinguistic boundaries between Spanish and Palenquero from the speakers' own perspective, including traditional native Palenquero speakers, adult heritage speakers, and young native Spanish speakers who are acquiring Palenquero as a second language. The latter group also provides insights into the possible cognitive cost of "de-activating" Spanish morphological agreement as well as the relative efficiency of pre-verbal vs. clause-final negation. In this study, corpus-based analyses are combined with an array of interactive experimental techniques, demonstrating that externally-imposed classifications do not always correspond to speakers' own partitioning of language usage in their communities"--Introduction -- 1.

Hand Gesture Recognition on Arduino Using Recurrent Neural Networks and Ambient Light
No full textTouching physical buttons to interact with public electronic devices has raised some concerns regrading disease transmission following the COVID-19 pandemic. The use of hand gestures as a touchless replacement sounds appealing, but comes with the challenge of recognizing which gesture is being performed by the user, with only the processing power of a microcontroller. This paper explores the use of recurrent neural networks (RNNs) and their derivatives to recognize hand gestures on an Arduino Nano 33 BLE. The neural networks receive input from 3 OPT101 photodiodes, which emit a voltage that increases with the intensity of light that hits them, meaning they can effectively track hand shadows cast by the user’s hand under ambient light. After testing various RNN-based neural network architectures, CNN-LSTMs produced the highest validation accuracy. However, due to issues with the testing setup, the highest validation accuracy measured for a CNN-LSTM was only 43%, indicating that further work is required.CSE3000 Research ProjectComputer Science and Engineerin
Acute effects of 6-hydroxydopamine on dopaminergic neurons of the rat substantia nigra pars compacta in vitro
No full text6-Hydroxydopamine (6-OHDA) is a neurotoxin which has been implicated in the degeneration of dopaminergic neurons of the substantia nigra pars compacta (SNc) in Parkinson's disease (PD), and is frequently used to produce animal models of the disease. The aim of our study, conducted on midbrain slices obtained from young Wistar rats, was to determine the little known acute effects of this toxin (0.2-2.0 mM; 10-20 min exposure; 34 degrees C) on electrophysiological properties, intracellular Ca2+ levels and dendritic morphology of SNc neurons. Four experimental approaches were used: extracellular recording of firing frequency, whole-cell patch-clamping, ratiometric fura-2 imaging, and cell labeling with lucifer yellow (LY) or dextran-rhodamine. Extracellular recording revealed a concentration-dependent decrease in the tonic, pacemaker-like firing. In whole-cell recordings in voltage-clamp (V(hold) -60 mV), smaller doses (0.2-0.5 mM) induced an outward current (or cell membrane hyperpolarization in current-clamp), which could in some cells be reversed with tolbutamide (blocker of ATP-dependent K+ channels). A higher dose (1.0-2.0 mM) caused rapid reductions of cell membrane capacitance and membrane resistance. Toxin exposure gradually increased the intracellular Ca2+ level, which did not subsequently return to control. The increase in Ca2+ signal was not prevented by depletion of intracellular Ca2+ stores with thapsigargin (10 microM) or cyclopiazonic acid (30 microM), nor by removing extracellular Ca2+. Cell membrane current and Ca2+ responses were not prevented by blocking dopamine transporter (DAT). Cells loaded with LY or dextran-rhodamine showed signs of damage (cell membrane blebbing) in dendrites following toxin exposure (1 mM; 10-20 min). These results demonstrate that the oxidative and metabolic stress induced in SNc neurons by 6-OHDA results in rapid dose-dependent changes of cell membrane properties with morphological evidence of dendritic damage, as well as in disturbance of intracellular Ca2+ homeostasis

sensitivity of dopaminergic neurons of the substantia nigra pars
compacta: involvement of Transient Receptor Potential channels.
J Neurophysiol 94: 3069–3080, 2005. First published July 13, 2005;
doi:10.1152/jn.00066.2005. Changes in temperature of up to several
degrees have been reported in different brain regions during various
behaviors or in response to environmental stimuli. We investigated
temperature sensitivity of dopaminergic neurons of the rat substantia
nigra pars compacta (SNc), an area important for motor and emotional
control, using a combination of electrophysiological techniques, microfluorometry,
and RT-PCR in brain slices. Spontaneous neuron
firing, cell membrane potential/currents, and intracellular Ca2 level
([Ca2]i) were measured during cooling by 10° and warming by
5° from 34°C. Cooling evoked slowing of firing, cell membrane
hyperpolarization, increase in cell input resistance, an outward current
under voltage clamp, and a decrease of [Ca2]i. Warming induced an
increase in firing frequency, a decrease in input resistance, an inward
current, and a rise in [Ca2]i. The cooling-induced current, which
reversed in polarity between 5 and 17 mV, was dependent on
extracellular Na. Cooling-induced whole cell currents and changes
in [Ca2]i were attenuated by 79% in the presence of 2-aminoethoxydiphenylborane
(2-APB; 200 M), and the outward current was
reduced by 20% with ruthenium red (100 M). RT-PCR conducted
with tissue punches containing the SNc revealed mRNA expression
for TRPV3 and TRPV4 channels, known to be activated in expression
systems by temperature changes within the physiological range.
2-APB, a TRPV3 modulator, increased baseline [Ca2]i, whereas
4PDD, a TRPV4 agonist, increased spontaneous firing in 7 of 14
neurons tested. We conclude that temperature-gated TRPV3 and
TRPV4 cationic channels are expressed in nigral dopaminergic neurons
and are constitutively active in brain slices at near physiological
temperatures, where they affect the excitability and calcium homeostasis
of these neurons
