Quantity and quality of literacy instruction for English language learners in Indiana elementary schools
Authors: Li Haiyan , Wright Wayne E. , Morita-Mullaney Trish 
Published: March 2023

Abstract
This research adopts a collective case study to explore the quantity (time allocations for key literacy components and group configurations) and the quality of English language arts (ELA) instruction for Grade 1 English language learners (ELLs) across six classrooms in three Indiana elementary school districts during the 2019–2020 school year. Three teachers (treatment group) were participants in a year-long professional development (PD) program consisting of ELL teacher licensure coursework (plus instructional coaching for two of the treatment teachers). The other three teachers (control group) did not participate in the PD program. Analysis of video-recordings of teachers’ ELA instruction, coded video instances, and time allocations reveal that overall treatment teachers allocated more time for the ELA block, more time for vocabulary, comprehension, and fluency instruction, and in general provided higher quality instruction. The findings provide evidence of the effectiveness of the PD program for improving ELA instruction for ELLs. However, both control and treatment teachers have some discrepancies in the quality and quantity of their literacy instruction compared to evidence-based research. This study holds important implications for literacy educators as they identify and employ strategies best suited for ELLs.

Abstract
The present work describes the synthesis, characterization, and evaluation of the antibacterial activity of a new poly azo compound resulting from the coupling of a previously reported N-arylsuccinimid precursor 5 with the diazonium ion of aniline. This azo compound was characterized using its physical, elemental, and 1D and 2D spectroscopic data. The novel azo compound 7 (minimum inhibitory concentration [MIC] = 16–32 μg/mL) showed higher antibacterial activity than its precursor 5 (MIC = 32–64 μg/mL), although it was low compared to the reference drug ciprofloxacin (MIC = 0.5–4 μg/mL).

Published: March 2023

Abstract

Objectives
To test if two e-learning modules – one on cognitive impairment, and one on continence and mobility – in older people would improve the knowledge of nurse members from the Canadian Gerontological Nurses Association and College of Licensed Practical Nurses of Alberta.

Methods
A pre-post-test design was used to test 88 nurses’ knowledge of cognitive impairment and 105 nurses’ knowledge of continence and mobility and their perceptions of how the modules contributed to their learning.

Results
There was a statistically significant increase in practicing nurses’ knowledge about cognitive impairment (0.68 increase), continence (2.30 increase), and its relationship to mobility. Nurses’ self-report on the feedback survey demonstrated increases in knowledge, confidence, and perceptions about older people.

Conclusion
These results suggest the modules have strong potential to enhance practicing nurses’ knowledge about cognitive impairment, continence, and mobility.

A case report of pseudoleukopenia: playing hide-and-seek
Authors: Wang Sixuan , Wang Xiaoxi , Shu Lingbin 
Published: March 2023

Abstract

Objectives
Routine blood examination, one of the most commonly performed tests in clinical laboratories, directly reflects the overall state of the body such as inflammation, anemia, and thrombocytopenia. The accuracy of these indicators by tests may be perturbed by various factors including anticoagulants, antibodies, and temperatures. Pseudoleukopenia caused by leukoagglutination was rarely described in the literature.

Case presentation
We report a rare and unusual pseudo-leukopenia case of a 75-year-old female with a stroke. Blood samples from the patient were collected using different anticoagulants and determined the hematologic parameters and blood smears. We observed the extent of leukocyte aggregation at different anticoagulants or temperatures. The intensity of leukoagglutination was attenuated after incubating at 37 °C for 30 min. After anti-infection treatment and symptomatic treatment, the leukoagglutination of the patient gradually weakened.

Conclusions
We have found the reason for the pseudo-leukopenia and the leukocyte aggregation phenomenon may vary with disease progression.

Between the Void and Emptiness: Ontological Paradox and Spectres of Nihilism in Alain Badiou’sBeing and Eventand Graham Priest’sOne
Authors: Newson Georgie 
Published: March 2023

AbstractIn this study, I reconstruct and compare Alain Badiou’sBeing and Event(2005) and Graham Priest’sOne(2014), arguing that the ontologies pursued within the two texts are intriguingly analogous in a number of ways. Both Badiou and Priest are committed to thinking through classically ontological problems without denying the validity of the paradoxes they raise; both regard Plato’sParmenidesas an early and formative account of these paradoxes; both establish conclusions to the effect that unity – or “oneness” – is indeed a contradictory phenomenon; and both, as a corollary of this conclusion, develop frameworks which confer ontological prominence uponthe voidandemptinessrespectively, thereby arriving at what appears to be a shared ontological nihilism. In this comparative study, I not only enquire whether the frameworks adopted by Badiou and Priest really do lead to nihilist conclusions, but also attempt to clearly outline their trajectories of thought for the benefit of those who might be tempted to dismiss their seemingly outlandish theses out of hand.

Abstract

Objectives
Up to one quarter of the patients with colorectal cancer (CRC) develop peritoneal carcinomatosis (PM). The aims of this retrospective study were to characterize the histological response of the PM of CRC to preoperative chemotherapy and evaluate the potential prognostic value, in terms of survival.

Methods
This retrospective unicentric study evaluated a group of 30 patients treated between 2010 and 2020 at the São João University Hospital Center with preoperative chemotherapy, followed by cytoreduction surgery plus hyperthermic intraperitoneal chemotherapy. The evaluation of the histological response was done using two scores: the tumor regression grading (TRG) and the peritoneal regression grading score (PRGS).

Results
Mean post-procedure survival is higher in the PRGS 1–2 group (74.19 months) vs. the PRGS 3–4 group (25.27 months) (p=0.045), as well as in the TRG 1–2 group (74.58 months) vs. TRG 4–5 (25.27 months) (p=0.032). As for progression-free survival (PFS), the PRGS 1–2 group had a mean value of 58.03 months vs. PRGS 3–4 which had 11.67 months (p=0.002). Similar was observed with the TRG 1–2 group, which had a mean PFS of 61.68 months vs. TRG 4–5 with 11.67 months (p=0.003).

Conclusions
A better histological response to preoperative chemotherapy, represented as a lower PRGS and TRG value, is associated with longer post-procedure survival and progression-free survival in this group of patients. That is, these two scores have prognostic value.
Tensiometric and rheological investigations of single and mixed systems consisting of cocamidopropyl betaine (CAPB) and sodium dodecyl benzene sulfonate (SDBS) in aqueous solutions

Published: March 2023

Abstract
The surface tension (σ), critical micelle concentration (CMC), surface excess (Γ), minimum area occupied by a surfactant molecule (A
min), the viscosity and oscillatory rheological studies of aqueous solutions containing cocamidopropyl betaine (CAPB) and sodium dodecylbenzene sulfonate (SDBS) at molar fractions of 0.00, 0.25, 0.50, 0.75 and 1.00 and 25 °C were presented. CAPB and SDBS were not found to interact synergistically in water at any of the molar fractions studied. This is due to the fact that the critical micelle concentrations of these mixtures were higher than those predicted by Clint’s equation, indicating an antagonism that rarely occurs in mixed amphoteric/anionic surfactant systems. The minimum area occupied by a surfactant molecule (A
min) was reduced in CAPB/SDBS mixtures compared to unmixed surfactants. In contrast, the viscosity of the mixed CAPB/SDBS system increased significantly from 1.0 mPa s to a maximum of 36.0 Pa s at higher CAPB mole fractions (0.5–0.8). The rheograms obtained from the oscillation measurements of the viscous CAPB/SDBS solutions are characteristic of wormlike micelles (WLMs) according to the Maxwell model. The results of this surprising binary CAPB/SDBS surfactant mixing system are presented and discussed.
Essential oil composition, anti-tyrosinase activity, and molecular docking studies of Knema intermedia Warb. (Myristicaceae)

Published: March 2023

Abstract

Knema is one of the genera in the Myristicaceae family. The genus includes 60 species in Southeast Asia and is traditionally used for treating skin disorders. Here, for the first time, the essential oil, anti-tyrosinase, and molecular docking studies of Knema intermedia were evaluated. The essential oil was obtained by hydrodistillation and fully characterized by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). Anti-tyrosinase activity was evaluated against mushroom tyrosinase, whereas molecular docking studies were performed using Autodock vina embedded in PyRx to evaluate the binding interactions of major components. A total of 37 components (97.3%) were successfully identified in the essential oil, which was characterized by high amounts of t-muurolol (20.1%), α-copaene (14.4%), δ-cadinene (13.9%), germacrene B (9.5%), and δ-selinene (7.0%). The essential oil displayed moderate inhibitory activity towards tyrosinase with an IC50 value of 70.2 μg/mL. The best docking energy was observed with δ-selinene (−7.8 kcal/mol), and it also forms interactions with His85, His263, and His244 which are important amino acid residues of the tyrosinase receptor. Hence, this study provides valuable scientific data on K. intermedia as potential candidate for the development of natural antiaging formulations.
Deciding While Acting—Mid-Movement Decisions Are More Strongly Affected by Action Probability than Reward Amount
Authors: Ulbrich Philipp , Gail Alexander 
Published: March 2023

AbstractWhen deciding while acting, such as sequentially selecting targets during naturalistic foraging, movement trajectories reveal the dynamics of the unfolding decision process. Ongoing and planned actions may impact decisions in these situations in addition to expected reward outcomes. Here, we test how strongly humans weigh and how fast they integrate individual constituents of expected value, namely the prior probability (PROB) of an action and the prior expected reward amount (AMNT) associated with an action, when deciding based on the combination of both together during an ongoing movement. Unlike other decision-making studies, we focus on PROB and AMNT priors, and not final evidence, in that correct actions were either instructed or could be chosen freely. This means, there was no decision-making under risk. We show that both priors gradually influence movement trajectories already before mid-movement instructions of the correct target and bias free-choice behavior. These effects were consistently stronger for PROB compared with AMNT priors. Participants biased their movements toward a high-PROB target, committed to it faster when instructed or freely chosen, and chose it more frequently even when it was associated with a lower AMNT prior than the alternative option. Despite these differences in effect magnitude, the time course of the effect of both priors on movement direction was highly similar. We conclude that prior action probability, and hence the associated possibility to plan actions accordingly, has higher behavioral relevance than prior action value for decisions that are expressed by adjusting already ongoing movements.
Alternative brain connectivity underscores age-related differences in the processing of interactive biological motion
Authors: Walbrin Jon , Almeida Jorge , Koldewyn Kami 
Published: March 2023

Rapidly recognizing and understanding others’ social interactions is an important ability that relies on deciphering multiple sources of information; for example, perceiving body information and inferring others’ intentions. Despite recent advances in characterizing the brain basis of this ability in adults, its developmental underpinnings are virtually unknown. Here, we used fMRI to investigate which sources of social information support superior temporal sulcus (STS) responses to interactive biological motion (i.e. 2 interacting point-light human figures) at different developmental intervals in human participants (of either sex): Children show supportive functional connectivity with key nodes of the mentalizing network, while adults show stronger reliance on regions associated with body- and dynamic social interaction/biological motion processing. We suggest that adults employ efficient action-intention understanding via body and biological motion information, while children show a stronger reliance on hidden mental-state inferences as a potential means of learning to better understand others’ interactive behavior.SIGNIFICANCE STATEMENT:Recognizing others’ interactive behavior is a critical human skill that depends on different sources of social information (e.g. observable body-action information, inferring others’ hidden mental-states etc.). Understanding the brain-basis of this ability, and characterizing how it emerges across development are important goals in social neuroscience. Here, we used fMRI to investigate which sources of social information support interactive biological motion processing in children (6-12 years) and adults. These results reveal a striking developmental difference in terms of how wider-brain connectivity shapes functional responses to interactive biological motion that suggests a reliance on distinct neuro-cognitive strategies in service of interaction understanding (i.e. children and adults show a greater reliance on explicit and implicit intentional inference, respectively).
L’empereur d’orient et l’empereur d’occident à Buda (1424) •
Authors: Schreiner Peter 
Published: March 2023

AbstractThe Byzantine emperors had never left their country until the second half of the 14th century, when John V Palaiologos undertook, with two of his sons, a journey to the court of Louis I to seek military aid against the Turks. Despite the failure of this first mission, from then on, contacts with the kings of Hungary determined Byzantine policy. They came to a head when John V’s grandson, John VIII, who replaced his father Manuel II, unable to govern because of an apoplexy, met Holy Roman Emperor Sigismund at Ofen (Buda) in 1424. This had been the first meeting between the rulers of the two empires since the coronation of Charlemagne in 800, and it was recorded by an eyewitness, Eberhard Windecke, who accompanied the Hungarian king during his travels.

Distance learning technologies in a higher educational institution: experience in using and implementing e-learning courses in the educational process
Authors: Kovalenko Oksana 
Published: March 2023

Distance learning technologies occupy a strong position in the higher education system: they can serve as an instrumental basis for organizing distance learning, they can be actively used in combination with traditional forms and methods of teaching, and they can be used to build networking between universities and employer organizations. There is much experience in using distance learning technologies by university teachers when working with students, which needs to be rethought.
The purpose of this study was to show how an educational platform, such as the S. Kuznets KNEU Personal Learning Systems, can be used to provide educational services in the face of unpredictable barriers in the current circumstances in Ukraine to substantiate the importance and feasibility of developing and implementing distance learning courses on this platform to increase the efficiency of distance learning.
The study reveals the importance of using distance learning technologies in the educational process. Distance learning offers many advantages, such as geographical diversity, efficiency, continuity, individual approach and personalized program. The article analyzes the experience of using distance learning technologies on the example of Simon Kuznets Kharkiv National University of Economics. The existing difficulties of using distance learning technologies are specified. The algorithm for using the Moodle distance learning system as a tool environment for developing online courses by teachers, distinguished by its functionality, flexibility, reliability and ease of use, is prescribed.
However, Ukraine's education system must catch up with the fundamentals underlying distance learning courses. It is necessary to train highly qualified teaching staff capable of working with students remotely to ensure the effectiveness of distance learning, provide students with updated learning materials, and make courses comprehensive, engaging, and easy to understand. However, the prospects in this area of education in Ukraine are prominent
