Background

Cancer patients with pelviabdominal masses can suffer from lower extremity symptoms due to venous compression. The effectiveness of venous stenting has been established in extrinsic venous compression in benign conditions like May-Thurner syndrome. In this retrospective study we evaluate the efficacy and safety of caval, iliocaval and iliofemoral venous stenting for cases of extrinsic venous compression caused by malignant masses in cancer patients.

Methods

IRB-approved retrospective review of patients who underwent iliofemoral venography with venoplasty and stenting between January 2018 and February 2022 was performed. Patients with extrinsic venous compression caused by malignant masses were included. Data on patient demographics, pre-procedure symptoms, procedural technique, stent characteristics, outcomes and follow-up were collected. Descriptive statistics were used to assess technical success, clinical success, primary stent patency and adverse events of the procedure.

Results

Thirty-seven patients (19 males, 18 females) who underwent 45 procedures were included. Deep venous thrombosis (DVT) was present in 21 (57%) patients. Twenty-nine patients (78%, 95% CI 62–90%) reported clinical improvement of the presenting symptoms. The median overall survival after the procedure was 4.7 months (95% CI 3.58–5.99). Eight (22%) patients were alive at last follow up with median follow up of 10.33 months (Range 2–25 months). Twenty-six patients had patent stents on their last follow up imaging (70%, 95% CI 61%-91%). Two patients had a small access site hematoma which resolved spontaneously. Two patients developed moderate, and 1 patient developed severe adverse events related to post procedure therapeutic anticoagulation.

Conclusion

Venous stenting is a safe procedure and should be considered as part of the palliative care for patients with debilitating lower extremity symptoms related to iliocaval and iliofemoral venous compression.

Published: March 2024

Background

Irrational use of antibiotics in hospitals is one of the main health system problems. It leads to antibiotic resistance, adverse events, treatment failure, total treatment costs, and longer hospital stay. We aim to evaluate clindamycin use in critical care units in our hospital. It is a step to assess and then put strategies to improve the antibiotic use process.

Methods

This is a clindamycin use evaluation retrospective study. It was done in critical care units at Alexandria’s main university hospital. The clinical pharmacists reviewed 99 patients’ prescriptions over the last 4 months, recording patients' demographics, main diagnosis, comorbidities, type of infection, duplication of therapy, dose, the occurrence of diarrhea, serious drug interactions, clindamycin-defined daily dose per 1000 patients’ days), treatment duration and total cost of clindamycin.

Results

A total of 99 patients were included. Clindamycin was prescribed in appropriate indications in 57 patients (57/99 = 57.6%). Prescriptions with inappropriate indications were 42 (42/99 = 42.4%). Duplication of therapy with clindamycin was detected in 32 prescriptions (32.3%). Diarrhea was recorded in 4% of the cases. There were no severe drug interactions with clindamycin. Inappropriate indications were 320 defined Daily Dose (DDD) of total clindamycin consumption (765 DDD) and a cost of 29951.5 LE (42% of total cost). The prescribed dose of clindamycin was correct in all cases.

Conclusion

There is irrational clindamycin use in critical care units in some cases regarding indications and treatment duplication. Although the prescribed doses were correct. Clindamycin misuse increased total consumption and cost.

Hyperparameter inversion of well logs for the simultaneous estimation of volumetric and zone parameters
Authors: Szabó Norbert Péter
Published: March 2024

We develop a new alternative for the joint inversion of well logs to predict the volumetric and zone parameters in hydrocarbon reservoirs. Porosity, water saturation, shale content, kerogen, and matrix volumes are simultaneously estimated with the tool response function constants with a hyperparameter estimation assisted inversion of the total and spectral natural gamma-ray intensity, neutron porosity, and resistivity logs. We treat the zone parameters, i.e., the physical properties of rock matrix constituents, shale, kerogen, and porefluids, as well as some textural parameters, as hyperparameters and estimate them in a metaheuristic inversion procedure for the entire processing interval. The selection of inversion unknowns is based on parameter sensitivity tests, which indicate that the automated estimation of several zone parameters is favorable, and their possible range can also be specified in advance. In the outer loop of the inversion procedure, we use a real-coded genetic algorithm for the prediction of zone parameters, and we update the volumetric parameters in the inner loop in addition to the fixed values of the zone parameters estimated in the previous step. We apply a linearized inversion process in the inner loop, which allows for the quick prediction of volumetric parameters along with their estimation errors from point to point along a borehole. The derived parameters, such as hydrocarbon saturation and total organic content, indicate good agreement with core laboratory data. The significance of the inversion method is that the zone parameters are extracted directly from the wireline logs, which improves the solution of the forward problem and reduces the cost of core sampling and laboratory measurements. In a field study, we demonstrate the feasibility of the inversion method using real well logs collected from a Miocene tight gas formation situated in the Derecske Trough, Pannonian Basin, East Hungary.
Russian Grain Procurement in a Revolutionary State
Authors: Fraunholtz Peter
Published: March 2024

The Russian provisional government and Bolshevik regime, in their respective efforts to address and resolve the food-supply crisis of 1917–19, sought to modernize state-village relations and mobilize peasant-citizens to contribute to the task according to their ability. Grain registration, an accounting of peasant grain stocks to find “surpluses,” was a continuation of a reformist trend within the state bureaucracy to replace customary means of allotting state obligations with an effort to base them on an assessment of household productive capacity. Evidence from Penza Province suggests that grain registration, both data gathering and interpretation, played a complex role in the evolution of grain procurement policy. The implementation of registration was impacted by local conditions and was embraced when and where it served local interests. Registration contributed to significant tensions within the state apparatus; it exacerbated the growth of the localism that undermined the authority of the hierarchical procurement apparatus. Grain registration revealed the adaptability of peasants and local officials in the face of top-down reform and prompted efforts to enhance state effectiveness. Ultimately, the persistent challenges posed by grain registration forced the regime to abandon registration and to reorganize the provincial apparatus to enhance oversight of local officials.

BACKGROUND AND OBJECTIVES:

Intracranial electrophysiology of thalamic nuclei has demonstrated involvement of thalamic areas in the propagation of seizures in focal drug-resistant epilepsy. Recent studies have argued that thalamus stereoencephalography (sEEG) may aid in understanding the epileptogenic zone and treatment options. However, the study of thalamic sEEG-associated hemorrhage incidence has not been investigated in a cohort study design. In this article, we present the largest retrospective cohort study of sEEG patients and compare hemorrhage rates between those with and without thalamic sEEG monitoring.

METHODS:

Retrospective chart review of clinical and epilepsy history, electrode implantation, rationale, and outcomes was performed for 76 patients (age 20-69 years) with drug-resistant epilepsy who underwent sEEG monitoring at our institution (2019-2022). A subset of 38% of patients (n = 30) underwent thalamic monitoring of the anterior thalamic nucleus (n = 14), pulvinar nucleus (n = 25), or both (n = 10). Planned perisylvian orthogonal sEEG trajectories were extended to 2- to 3-cm intraparenchymally access thalamic area(s).The decision to incorporate thalamic monitoring was made by the multidisciplinary epilepsy team. Statistical comparison of hemorrhage rate, type, and severity between patients with and without thalamic sEEG monitoring was made.

RESULTS:

Our approach for thalamic monitoring was not associated with local intraparenchymal hemorrhage of thalamic areas or found along extended cortical trajectories, and symptomatic hemorrhage rates were greater for patients with thalamic coverage (10% vs 0%, P = .056), although this was not found to be significant. Importantly, patients with perisylvian electrode trajectories, with or without thalamic coverage, did not experience a higher incidence of hemorrhage (P = .34).

CONCLUSION:

sEEG of the thalamus is a safe and valuable tool that can be used to interrogate the efficacy of thalamic neuromodulation for drug-resistant epilepsy. While patients with thalamic sEEG did have higher incidence of hemorrhage at any monitoring site, this finding was apparently not related to the method of perisylvian implantation and did not involve any trajectories targeting the thalamus.

Η παρούσα διατριβή μελετά την οπτική των θεραπευόμενων για τους θεραπευτικούς παράγοντες που λειτουργούν σε ομαδική θεραπεία μακράς διάρκειας συνθετικού συστημικού προσανατολισμού (ΣΣΠ). Τα ερευνητικά ερωτήματα της μελέτης είναι: α) πώς προσδιορίζουν οι θεραπευόμενοι το είδος βοήθειας που πήραν από ομαδική θεραπεία μακράς διάρκειας ΣΣΠ, β) πώς προσδιορίζουν το είδος βοήθειας που έλαβαν στην αρχική, την προχωρημένη και την τελική φάση της θεραπείας, γ) πώς βιώνεται η λειτουργία των θεραπευτικών παραγόντων από τους θεραπευόμενους στη λεπτομέρεια, τον πλούτο και την πολυπλοκότητα της εμπειρίας τους. Για τη μελέτη επιλέχθηκε η μέθοδος της ποιοτικής έρευνας με συνεντεύξεις από τους θεραπευόμενους-μέλη των ομάδων, σε τρεις φάσεις, έτσι ώστε να διερευνηθούν οι διαφορές στην οπτική των συμμετεχόντων στην αρχική, την προχωρημένη και την τελική φάση της ομαδικής ψυχοθεραπείας. Στην πρώτη φάση ελήφθησαν ημι-δομημένες συνεντεύξεις από τα μέλη δύο ομάδων ψυχοθερα¬πείας μακράς διάρκειας ΣΣΠ τον πρώτο χρόνο της ομαδικής ψυχοθεραπείας τους. Στη δεύτερη και την τρίτη φάση ελήφθησαν ημιδομημένες συνεντεύξεις από τους ίδιους συμμετέχοντες τον δεύτερο και τρίτο χρόνο της συμμετοχής τους στην ομάδα, αντίστοιχα. Το δείγμα της έρευνας είναι 13 άτομα και των δύο φύλων. Η ανάλυση των δεδομένων πραγματοποιήθηκε με τη μέθοδο της Ερμηνευτικής Φαινομενολογικής Ανάλυσης. Τα αποτελέσματα επιβεβαιώνουν σε μεγάλο βαθμό την ταξινόμηση των θεραπευτικών παραγόντων του Yalom για την ομαδική θεραπεία μακράς διάρκειας ΣΣΠ. Ωστόσο, πέρα από τους 11 αναμενόμενους θεραπευτικούς παράγοντες, προέκυψε ως εύρημα ένας επιπλέον θεραπευτικός παράγοντας που είναι η «ανάπτυξη πλουραλιστικής οπτικής». Πρόκειται για έναν θεραπευτικό παράγοντα που αναφέρεται σε διαδικασίες ανάλογες με αυτές που περιγράφουν σύγχρονες έρευνες της αναπτυξιακής ψυχολογίας γύρω από τη «θεωρία του νου». Ο νέος αυτός θεραπευτικός παράγοντας εμφανίζεται ως διακριτός από τον δεύτερο χρόνο της θεραπείας και έπειτα, ενώ στην πρώτη φάση της θεραπείας εμφανίζεται ως υποκατηγορία της θεματικής κατηγορίας «ανάπτυξη τεχνικών κοινωνικοποίησης». Επιπλέον, συγκριτικά με την πρώτη φάση της έρευνας, προκύπτουν διαφορές το δεύτερο και τρίτο χρόνο της ομαδικής θεραπείας στον τρόπο που οι συμμετέχοντες αντιλαμβάνονται τους «υπαρξιακούς παράγοντες» και τη «διαπροσωπική μάθηση», όπως αποκαλύπτουν οι πρόσθετες υποκατηγορίες στους συγκεκριμένους θεραπευτικούς παράγοντες. Τέλος, τα αποτελέσματα της έρευνας φωτίζουν σε βάθος την εμπειρία των συμμετεχόντων από την ομαδική ψυχοθεραπεία ΣΣΠ μακράς διάρκειας και, επομένως, αναδεικνύουν με περισσότερη λεπτομέρεια τον ιδιαίτερο τρόπο λειτουργίας κάθε θεραπευτικού παράγοντα.

Published: March 2024

Digital Twin Workshop(DTW), as an important approach to digitalization and intelligentization of workshop, has gained significant attention in manufacturing industry. Currently, digital twin models for manufacturing resources have progressed from theoretical research to practical implementation. However, as a crucial component of workshop, modeling of human activity in workshop still faces challenges due to the autonomy and uncertainty of human beings. Therefore, we propose a comprehensive approach to the modeling cross-scale human activity in digital twin workshop, which comprises macro activity and micro activity. Macro activity contains human’s occupation and spatial positions in workshop, while micro activity refers to real-time posture and production actions at work. In this paper, we build and integrate macro activity digital twin model and micro activity digital twin model. With the combination of closed-loop interaction between virtual models and physical entities, we achieve semantic mapping and control of production activities, thereby facilitating practical management of human activity in workshop. Finally, we take certain factory’s manufacturing workshop as an example to introduce the application of the proposed approach.

Introduction: Tuberculosis (TB) is a global public health problem, endemic to India. Osteoarticular TB uncommonly presents in the foot, navicular osteomyelitis is an extremely rare entity. Case Report: We report a rare case of navicular osteomyelitis caused by TB in a 37-year-old man who presented to OPD with swelling and dull aching pain over the dorsum of his left foot. A radiograph of the foot showed a lytic lesion in the navicular bone. Further investigations in the form of aspiration cytology, cartridge-based nucleic acid amplification test, and acid-fast bacilli culture confirmed TB. Category-1 anti-tubercular therapy was started immediately and the patient was treated conservatively. Four drugs (HRZE) were given for 2 months and 3 drugs (HRE) for 9 months, after which the patient stopped his medications on his own. Radiographs and CEMRI at 14-month follow-up showed a healed lesion. Conclusion: This case illustrates an exceptional location of osteoarticular TB and shows that Navicular TB can be treated conservatively with near-complete function and recovery if diagnosed early. Keywords: Navicular TB, ATT, foot and ankle TB.

Introduction: An aneurysmal bone cyst (ABC) is an unusual, non-cancerous bone lesion that is characterized by its lytic (causing bone loss), hemorrhagic, and expanding nature. ABCs are relatively rare, making up only 1% of all bone tumors. These cysts are typically found in long bones and the spine but are very rarely seen in the metatarsal bones, making such occurrences quite uncommon. Case Report: In this case report, we present a case of ABC of the 3rd metatarsal in a 26-year-old female with complaints of long-standing foot pain and gradually increasing swelling of the dorsum of the foot. After radiological evaluation, she had undergone histopathological evaluation. An en bloc resection of the metatarsal along with the tumor mass was performed and the gap was replaced with an ipsilateral fibular strut graft. Histopathological examination of the resected tissue was suggestive of ABC without any evidence of malignancy. At the end of 1 year of follow-up, she is now completely pain free with intact rom of foot and ankle. Conclusion: The present study aims to describe a case of ABC of the metatarsal, a condition that not only poses a diagnostic dilemma but also constitutes a challenge in the management of lesion. Keywords: Aneurysmal bone cyst, metatarsal bone, foot swelling.

Introduction: Intra-articular and periarticular distal femur fractures with pre-existing osteoporosis (OP) and osteoarthritis (OA) pose a significant challenge to ambulatory patients because of the higher chances of implant failure and severe disability of OA. To reduce OA-related morbidity, we advocate simultaneous total knee arthroplasty (TKA) with fracture fixation instead of fracture fixation alone using computer-assisted navigation to achieve proper ligament balance, restoration of the mechanical axis, and component alignment. Case Report: A case series of four patients (male – 2 and females – 2) with periarticular fractures of the distal femur with severe OA and OP were primarily fixed with different modalities such as distal femur locking plates, cannulated-cancellous screw, and Herbert screw followed by computer navigation-assisted cruciate retaining TKA. All patients had Kellgren Lawrence grade ≥3 OA and underwent bilateral TKA. All patients were aggressively treated for OP using pulsed PTH therapy. Patients were found to have a faster recovery with the initiation of early partial weight bearing with crutches postoperatively in all patients, followed by unassisted weight bearing once radiological union was seen. Conclusion: Based on satisfactory quality evidence and navigation-assisted cruciate-retaining TKA appears to be a useful treatment option for distal femoral fractures with pre-existing OA and OP. This is cost-effective and is associated with the least morbidity and excellent patient satisfaction. Keywords: Total knee arthroplasty, distal femur fracture, osteosynthesis.

Three Miles, Two Creeks: Local Pennsylvania History in the Classroom
Authors: Slavishak Edward
Published: March 2024

Abstract: This article describes an undergraduate history assignment at Susquehanna University, through which students create virtual museum exhibits on the local history of Selinsgrove,
Pennsylvania. Students narrate and interpret the Penn's Creek Massacre of 1755 and the Stump Massacre of 1768. The goal is to tell a cohesive story and offer a clear viewpoint
on the events while adhering to the research and design standards used by public history professionals. The historical content of the assignment emphasizes the diversity and
violence of the American frontier in the decades before the Revolutionary War. The exhibition format highlights the need to think carefully about audience, voice, and storytelling,
three aspects of making history that are often disregarded in student research papers. The ultimate value of the assignment is its ability to increase students' awareness of
the manipulation involved in the process of historical interpretation, even as they attempt to “get it right.”
An Authentic Archival Experience for the College Classroom in the Digital Age
Authors: Meier Kathryn Shively , Yarmey Kristen
Published: March 2024

Abstract: One of the most treasured experiences of historians is archival research, and yet university professors frequently struggle with viable ways to include archival research in their lecture courses. Further, historians, who are generally focused on the content of documents, often fail to provide students with a sense of the process by which historical documents and artifacts are gathered, preserved, and made available. This essay describes a partnership among faculty at the University of Scranton, the Lackawanna Historical Society, Weinberg Memorial Library, Scranton Public Library, and Everhart Museum to create an archival-based digital project for a course on the Civil War and Reconstruction. The students from the course uncovered uncataloged Civil War—era documents and artifacts, preserved, digitized, and transcribed them, and organized them into an online collection. The project acquainted students with local, firsthand historical accounts; introduced then to the complexity of recreating history from archival sources; exposed them to careers in archives, museum studies, and librarianship; and forged a partnership between university students and local institutions.
STCS-Net: a medical image segmentation network that fully utilizes multi-scale information
Authors: Ma Pengchong , Wang Guanglei , Li Tong , Zhao Haiyang , Li Yan , Wang Hongrui
Published: March 2024

In recent years, significant progress has been made in the field of medical image segmentation through the application of deep learning and neural networks. Numerous studies have focused on optimizing encoders to extract more comprehensive key information. However, the importance of decoders in directly influencing the final output of images cannot be overstated. The ability of decoders to effectively leverage diverse information and further refine crucial details is of paramount importance. This paper proposes a medical image segmentation architecture named STCS-Net. The designed decoder in STCS-Net facilitates multi-scale filtering and correction of information from the encoder, thereby enhancing the accuracy of extracting vital features. Additionally, an information enhancement module is introduced in skip connections to highlight essential features and improve the inter-layer information interaction capabilities. Comprehensive evaluations on the ISIC2016, ISIC2018, and Lung datasets validate the superiority of STCS-Net across different scenarios. Experimental results demonstrate the outstanding performance of STCS-Net on all three datasets. Comparative experiments highlight the advantages of our proposed network in terms of accuracy and parameter efficiency. Ablation studies confirm the effectiveness of the introduced decoder and skip connection module. This research introduces a novel approach to the field of medical image segmentation, providing new perspectives and solutions for future developments in medical image processing and analysis.

Published: March 2024

Objective

Xuebijing injection (XBJ) is a commonly used herbal medicine injection in China. However, the physical compatibility of XBJ with other intravenous drugs remains unclear. The purpose of this research is to evaluate physical compatibility of Xuebijing injection (XBJ) with 53 intravenous drugs (including 31 Chinese medicine injections and 22 chemicals) during simulated Y-site administration.

Methods

Y-site administration was simulated in vitro by admixing 0.33 ml/ml XBJ with an equal volume of other diluted 53 intravenous drugs, respectively. Physical compatibility including visual inspection, Tyndall beam, particle limits, turbidity, pH, chromacity value, spectroscopic absorption of 550 nm and 420 nm (A550 nmand A420 nm) were observed and assessed at 0, 1, 2, and 4 h. Physical compatibility was defined as all solutions with no color changes, no gas evolution, particulate formation and no Tyndall beam within 4 hours, turbidity changes <0.5 nephelometric turbidity unit (NTU) compared to 0 h, particle limits allowed by the Chinese Pharmacopoeia (Ch.P) 2020 edition, pH changes <10% compared to 0, chromacity value changes <200 compared to 0 h, or photometrical changes of A420 nm<0.0400 or A550 nm<0.0100 compared to 0 h.

Results

XBJ was physically incompatible with 27 of the 53 intravenous drugs tested, 26 were compatible with XBJ for 4 h.

Conclusions

XBJ should not be simultaneously co-administered with 27 of the 53 intravenous drugs during simulated Y-site. If coadministration was inevitable, flushing tube with NS or D5W before and after infusion of XBJ was needed. Assessment included visual inspection, Tyndall beam, turbidity measurement, particle counts, pH measurement, chromacity value measurement and absorption of A550 nmwere proved to be valid and robust for the quality control of infusion and compatibility of Chinese herbal injection.

Published: March 2024

The jaguar (Panthera onca) is a charismatic species considered Vulnerable in Colombia but yet largely unknown in the country. The species is mostly threatened by the continuous decline in its habitats, mostly derived from deforestation and habitat loss, additional to hunting and conflicts with humans. Thus, the future of jaguars in Colombia depends on protecting and recovering existing habitats. The aims of this study were to 1) evaluate jaguar distribution and identify the remnant patches of habitat in Colombia, 2) define an ecological connectivity network within the country, and 3) propose a priority areas portfolio for the conservation and recovery of jaguars. We used a presence background model for estimating species potential distribution and subsequently identified remaining habitat patches across the country based on land cover and species-specific ecological attributes. We then created an ecological connectivity network based on circuit theory and following a multi-criteria approach identified jaguar priority areas for conservation (JPCA) and recovery (JPRA). Jaguar potential distribution comprises 1103122.43 km2, from which 56.71% maintain suitable patches of potential habitat. We identified 960 corridors between remnant patches of natural or semi-natural vegetation. Based on the criteria, JPCAs with greater importance were identified in each of the five Colombian regions. JPRAs were located mainly towards the Andean and Caribbean regions. These JPCAs and JPRAs could serve as a guide for designing and implementing management strategies for the long-term conservation and recovery of the species in Colombia.

Published: March 2024

Updated recommendations on preseason heat safety in high school (HS) athletics (“2021 Consensus Statements”) were published in April 2021. This cross-sectional survey study explored the initial roll-out of the 2021 Consensus Statements, including their visibility among United States HS athletic trainers (ATs) and perceived levels of confidence in implementing them. Recruitment occurred first, from a random selection of ATs from the Board of Certification, Inc., and second, an open invitation via social media. An online cross-sectional questionnaire had participating ATs note whether they had seen the 2021 Consensus Statements. If yes, ATs reported their perceived level of confidence in implementing them (5-point-ordinal scale from “not at all confident” to “very confident); if no, ATs disclosed (open-ended) why they had not yet seen them. Descriptive statistics were calculated for quantitative variables; template analysis identified codes related to visibility of and confidence in implementing 2021 Consensus Statements. Nearly half (45.7%) of 116 responding HS ATs reported having seen at least one 2021 Consensus Statements; 23.3% had reviewed all three. Common reasons among the 63 that had not seen them included: not aware they were published (n = 22), have yet to read them (n = 19), and believed they could not access the journal (n = 10). Of the 53 ATs having seen at least one of the 2021 Consensus Statements, 67.9% (n = 36) were very/fairly confident in implementing them at their HS. Reasons for confidence included their schools ensuring up-to-date EHI prevention and management practices (n = 18) and athletics constituent support (n = 8). This exploratory study observed proportions of surveyed HS ATs that had not seen the 2021 Consensus Statements and were not confident in implementing them. Findings highlight the need to continue improving messaging about access to best-practice recommendations. Further, continued efforts inclusive of active and passive dissemination strategies across all athletics constituents are needed to aid proper implementation.
No evidence for adult smartphone use affecting attribution of communicative intention in toddlers: Online imitation study using the Sock Ball Task
Authors: Flatebø Solveig , Óturai Gabriella , Hernik Mikołaj
Published: March 2024

Adults infer others’ communicative intentions, or lack thereof, from various types of information. Young children may be initially limited to attributions based on a small set of ostensive signals. It is unknown when richer pragmatic inferences about communicative intentions emerge in development. We sought novel type of evidence for such inferences in 17-to-19-month-olds. We hypothesized that toddlers recognize adults’ smartphone use in face-to-face interactions as incongruous with ostension and would rely on this interpretation when inferring the communicative intention of a model in a new imitation task conducted entirely online, dubbed the Sock Ball Task. In Experiment 1 with a between-subject design, we tested the hypothesis by assessing toddlers’ (N = 48) imitation of sub-efficient means and the goal-outcome presented by a model, who interrupted her ostensive demonstration either by using a smartphone or by fiddling with her wristwatch, depending on the condition. We expected toddlers to imitate the sub-efficient means more faithfully in the wristwatch condition than in the smartphone condition. But there was no significant effect of condition on imitation of neither means nor goal. Thus, our hypothesis was not borne out by the results. In Experiment 2, using a within-subject design, we first assessed toddlers’ (N = 24) performance in a no-demonstration baseline and then again after a no-disruption ostensive demonstration. In all three conditions with ostensive demonstration (Experiment 1: smartphone, wristwatch; Experiment 2: no-disruption), toddlers produced the demonstrated sub-efficient means significantly above the baseline level. In the no-disruption condition, goals were also imitated significantly above the baseline level. We conclude that the Sock Ball Task is a valid research tool for studying toddler imitation of novel means actions with objects. We end by discussing suggestions for improving the task in future studies.
‘I take them on as if facts in a book’: Sex educators’ cumulative witnessing of sexual trauma
Authors: Hare Kathleen (Kaye) A.
Published: March 2024

Through a visual essay, the author explores the intersection of trauma and sexual health education (SHE) using art-based expressions from an ethnographic exploration of novice educators’ embodied experiences of SHE training. In particular, the author examines educators’ engagements with two forms of trauma: (1) self-trauma: trauma personally experienced by sex educators and (2) trauma transposition: other individuals’ disclosures of past harms to the educators. The author theorizes these engagements together as a form of cumulative witnessing – the collective, excessive consumption of violence through direct and vicarious exposures. Inspired by palimpsest methods, carbon tracing paper and photography were used to express the educators’ cumulative witnessing of sexual traumas via visually layering their words, drawings and expressed feelings about the sexual traumas that thread through SHE. The inquiry highlights key implications for SHE pedagogical practices, including acknowledging trauma, dealing with trauma disclosures and learning from and with trauma.
Politics of phygital protests: Palestinian #GreatMarchofReturn discourse on Twitter
Authors: Majeed Tawseef , Abushbak Ali M.
Published: March 2024

Twitter aids public discourse, hashtag activism and sociopolitical advocacy. In terms of Palestinian resistance discourse against Israel, the hashtag #GreatMarchofReturn represents a peaceful digital protest by the Palestinian refugees based in Gaza. We identified 13,000 tweets related to #GreatMarchofReturn, which we analysed using content analysis and descriptive analysis, followed by a visualization of the findings. We argue that hashtag activism facilitates the collective Palestinian protest discourse on Twitter about Israel’s oppressive diplomacies in Palestine. The activism endorses Palestinian nationalism and the mobilization of civilian rights. Moreover, the micro-blogging site becomes a significant platform for politicizing Israel’s punitive populism and subsequent subjugation of Palestinian refugees, especially in Gaza. The psycho-politics of phygital protests affects the socio-emotional mobilization of the Great March of Return in both virtual and physical public spheres.
Fractured and fragmented selves: Queer approaches to designing virtual experiences1,2
Authors: Burrell Andrew , Braithwaite Alexandra Chalmers
Published: March 2024

This article presents an overview of three queer virtual reality projects, Virtual Drag (2016), Domestika (2017) and Untitled (2020). These are considered alongside other examples and design experiments by the authors that also take a critical, queer approach to representing bodily forms in virtual environments. This consideration includes looking at how bodies are represented in the environment that the participant explores, as well as the embodied experience of the participant visiting the environment either via a head-mounted display or via desktop. Through the discussion of queerly performed embodiment offered by these precedents, we propose a queer sensibility of disembodied presentness for virtual reality that embraces a position of immersion and presentness in multiple physical and virtual realities at once, as a theoretical and aesthetic grounding principle. Queering of presentness is a key concept that emerges through these works, in part due to the multiplicity of perspectives that VR affords. In Virtual Drag (2016) by Alison Bennett, Megan Beckwith and Mark Payne, we see the use of photogrammetry and glitch aesthetics to bring ideas of queer performativity and drag ‘realness’ to the fore when imaging bodies with permeable, porous boundaries in virtual reality. In Domestika (2017) by Jacolby Satterwhite, the virtual environment is populated with multiple avatars that repeat recordings of the artist’s dance performances; in this multiplicity of repeated traces, a viewer is unable to settle on a fixed representation of the artist’s self. This effect is amplified by the participant’s non-corporeal presence, demonstrating the creative potential of queer disorientation in virtual environments. In Untitled (2020) by Tarik Ahlip and Tactical Space Lab, we are immersed in a cinematic environment, filled with simulated light. There, we encounter the artist’s body, disembodied and forcing the viewer into the role of virtual voyeur and onlooker to actions out of time.
Presence, absence, distance and intimacy: How do virtual classical music concerts rate against the wonders of the musical metaverse?
Authors: Teniswood-Harvey Arabella
Published: March 2024

Disruptions to live performance caused by the recent pandemic have fuelled a surge in virtual concerts, impacting both classical and popular music. This article explores ways in which audio-visual media have been used during the pandemic to maintain the live performance of classical music, through comparison with recent examples of virtual creativity in popular music (including performances by virtual artists in virtual spaces, Vocaloid and holographic concerts). Insights into audience experience are revealed: the benefits of engaging with music performance through online platforms include opportunities for social interaction, agency and an enhanced sense of community. Yet this participatory approach challenges the attentive listening mode embedded in the long-held conceptualization of classical music, and the new modes of performance and communication challenge established beliefs about the superiority of live performance over recording. Opportunities for creativity and audience experience and development are found in the notions of distributed creativity, distributed listening and the democratization of culture that are embedded in many of the practices of virtual music concerts. Analysing scholarly literature, music criticism, commentary and selected case studies, the article explores these ideas and opportunities through four episodes entitled to capture prominent themes: presence, absence and distance, intimacy and wonder.

Published: March 2024

Propõe-se, nesse artigo trazer reflexões sobre a concepção de felicidade no trabalho docente no município de Agudo/RS, com a intenção de compreender as representações de felicidade no trabalho de docentes da rede de ensino do município. Objetiva-se analisar e refletir em que medida as condições de trabalho docente impactam nos níveis de felicidade a partir de categorias como modelo salarial, papel político e social do trabalhador docente, condições de trabalho desiguais, emoções, a concepção de felicidade de cada docente em seu modo de viver. Esse artigo justifica-se pela necessidade de promover um estudo mais aprofundado sobre o tema felicidade no âmbito do trabalho docente na área das ciências sociais, pois considera-se que a temática se caracteriza como relevante e atual, podendo reunir informações que contribuam com a compreensão das representações da felicidade e práticas contemporâneas e com futuras pesquisas sobre o tema. O público alvo, foram docentes, do turno da noite, da Escola Estadual de Educação Básica Professor Willy Roos, localizada no município de Agudo/RS. Trata-se de uma pesquisa de abordagem quali–quantitativa e utilizará ferramentas metodológicas como análise bibliográfica, pesquisa documental e questionário. Conclui-se que os pesquisados internalizam suas emoções e perspectivas no ambiente de trabalho, como um modo de realização pessoal e missão de vida. De um modo geral, são profissionais que precisam ser incentivados e mobilizados com frequência, e necessitam antes de tudo, se sentir parte do processo, como um ser promissor em seu potencial, e assim se sentirem felizes e protagonista de sua trajetória de vida e profissional.
