The population trend of the largest breeding colony of the Indian Swiftlet Aerodramus unicolor: is it on the verge of extinction?
Authors: Kawalkar Dhanusha , Manchi Shirish S.
Published: April 2024

Fluctuations in animal populations are indicators of environmental change. Populations of the Indian Swiftlet Aerodramus unicolor on the Burnt and Old Lighthouse islands of Vengurla rocks, Sindhudurg district, Maharashtra were assessed using the logistic growth model. The study used secondary literature and primary surveys to estimate breeding population sizes on both islands. To understand population dynamics, we calculated the carrying capacity (K) using the Verhulst population growth model, and the percent rate of change in populations. Swiftlet populations on both islands are considered to be the maximum size their habitat can sustain, not exceeding 5,000 and 246 birds on Burnt and Old Lighthouse islands, respectively. These populations were observed to fluctuate between 2020 and 2023, with change rates of 5.5% on Burnt Island, and -53% on Old Lighthouse Island. The logistic growth model indicates that these Indian Swiftlet populations are fluctuating near the carrying capacities of their habitats, which could gradually lead to extinction. This highlights the urgent need for conservation and regular monitoring of these populations in Vengurla rocks.
A Systematic Review of the Efficacy and Safety of Tenecteplase Versus Alteplase in Acute Ischemic Stroke: A Time to Pass the Torch
Authors: Rodriguez Miguel , Sidebottom Christian , Wells Drew A. , Dhasakeerthi Thirumalaivasan , Hayes Lisa , Elangovan Cheran , Krishnaiah Balaji
Published: April 2024

Alteplase, a biosynthetic form of human tissue‐type plasminogen activator, is Food and Drug Administration‐approved for the treatment of acute ischemic stroke and currently the standard of care for thrombolytic therapy. Tenecteplase, a modified form of alteplase using recombinant technology, has several pharmacological advantages over alteplase, including longer half‐life, higher fibrin specificity, and greater resistance to plasminogen activator inhibitor‐1. Additionally, tenecteplase is given as a single bolus administration compared to the bolus plus 1‐hour continuous infusion of alteplase. Given these pharmacologic and logistical differences along with studies demonstrating noninferiority compared with alteplase, tenecteplase has become an alternative thrombolytic for the management of acute ischemic stroke. There is a growing body of evidence that suggests tenecteplase is a safe and effective alternative to alteplase. This systematic review evaluates the available literature for the use of tenecteplase in acute ischemic stroke and provides relevant discussion regarding role in therapy, therapeutic strategies, and areas requiring further research.

Published: April 2024

Background

Stereotactic thrombolysis for evacuation of large spontaneous intracerebral (ICH) and intraventricular hemorrhage (IVH) typically requires stabilizing the hemorrhage preoperatively. We investigated intracranial hemorrhage expansion (HE) in the pre‐ and postrandomization phase of 2 clinical trials of surgical candidates with protocolized computed tomography (CT) imaging up to 10 days after presentation.

Methods

Prospective assessment of sequential pre‐ and post‐randomization CT scans of 141 patients enrolled in MISTIE (Minimally Invasive Surgery Plus Alteplase for Intracerebral Hemorrhage Evacuation) II/ICES (Intraoperative CT‐guided Endoscopic Surgery for ICH) and 499 patients enrolled in MISTIE III. Primary outcomes were prerandomization HE of ICH >6 mL and IVH >5 mL. Secondary outcome was postrandomization HE. Stability was defined as CT time after which no further HE was observed. We evaluated risk factors for ICH/IVH expansion using multivariable logistic regression analyses after adjustment for demographics, ICH characteristics and treatment.

Results

Median (interquartile range) diagnostic ICH volume was 40.4 (29.5–54.1) mL. Prerandomization HE >6 mL was detected in 216 (33.8%) subjects. Median time to hematoma stability from diagnostic CT was 7 (4.7–13.6) hours. Median diagnostic IVH volume was 0 (0–1.9) mL. IVH expansion >5 mL occurred in 40 (6.3%) with stability at 6.9 (4.7–11.2) hours. Of subjects with HE, final expansion events were not yet detected at 12 hours from diagnostic CT in 36% (ICH expansion) and 33% (IVH expansion), respectively, with 91% detected by 24 hours. Independent associations with ICH expansion included age, male sex, White race, anticoagulation, ICH volume, deep ICH location, IVH, and time from symptom onset to diagnostic CT. Postsurgical ICH expansion occurred in 24 patients (6.9%) and was associated with delay in achieving stability, number of alteplase doses, and fewer CT hypodensities on diagnostic CT but not with functional outcome.

Conclusion

In patients with a large ICH eligible for surgical evacuation, about two thirds of HE events stabilize within 12 hours and most within 24 hours. An earlier time window for stereotactic thrombolysis may be feasible.
How Does the Inner Retinal Network Shape the Ganglion Cells Receptive Field? A Computational Study
Authors: Kartsaki Evgenia , Hilgen Gerrit , Sernagor Evelyne , Cessac Bruno
Published: April 2024

We consider a model of basic inner retinal connectivity where bipolar and amacrine cells interconnect and both cell types project onto ganglion cells, modulating their response output to the brain visual areas. We derive an analytical formula for the spatiotemporal response of retinal ganglion cells to stimuli, taking into account the effects of amacrine cells inhibition. This analysis reveals two important functional parameters of the network: (1) the intensity of the interactions between bipolar and amacrine cells and (2) the characteristic timescale of these responses. Both parameters have a profound combined impact on the spatiotemporal features of retinal ganglion cells’ responses to light.

The validity of the model is confirmed by faithfully reproducing pharmacogenetic experimental results obtained by stimulating excitatory DREADDs (Designer Receptors Exclusively Activated by Designer Drugs) expressed on ganglion cells and amacrine cells’ subclasses, thereby modifying the inner retinal network activity to visual stimuli in a complex, entangled manner. Our mathematical model allows us to explore and decipher these complex effects in a manner that would not be feasible experimentally and provides novel insights in retinal dynamics.
Dense Sample Deep Learning
Authors: Hanson Stephen José , Yadav Vivek , Hanson Catherine
Published: April 2024

Deep learning (DL), a variant of the neural network algorithms originally proposed in the 1980s (Rumelhart et al., 1986), has made surprising progress in artificial intelligence (AI), ranging from language translation, protein folding (Jumper et al., 2021), autonomous cars, and, more recently, human-like language models (chatbots). All that seemed intractable until very recently. Despite the growing use of DL networks, little is understood about the learning mechanisms and representations that make these networks effective across such a diverse range of applications. Part of the answer must be the huge scale of the architecture and, of course, the large scale of the data, since not much has changed since 1986. But the nature of deep learned representations remains largely unknown. Unfortunately, training sets with millions or billions of tokens have unknown combinatorics, and networks with millions or billions of hidden units can't easily be visualized and their mechanisms can't be easily revealed. In this letter, we explore these challenges with a large (1.24 million weights VGG) DL in a novel high-density sample task (five unique tokens with more than 500 exemplars per token), which allows us to more carefully follow the emergence of category structure and feature construction. We use various visualization methods for following the emergence of the classification and the development of the coupling of feature detectors and structures that provide a type of graphical bootstrapping. From these results, we harvest some basic observations of the learning dynamics of DL and propose a new theory of complex feature construction based on our results.
Semantics of Multiword Expressions in Transformer-Based Models: A Survey
Authors: Miletić Filip , Walde Sabine Schulte im
Published: April 2024

Multiword expressions (MWEs) are composed of multiple words and exhibit variable degrees of compositionality. As such, their meanings are notoriously difficult to model, and it is unclear to what extent this issue affects transformer architectures. Addressing this gap, we provide the first in-depth survey of MWE processing with transformer models. We overall find that they capture MWE semantics inconsistently, as shown by reliance on surface patterns and memorized information. MWE meaning is also strongly localized, predominantly in early layers of the architecture. Representations benefit from specific linguistic properties, such as lower semantic idiosyncrasy and ambiguity of target expressions. Our findings overall question the ability of transformer models to robustly capture fine-grained semantics. Furthermore, we highlight the need for more directly comparable evaluation setups.
Climate Change and India’s Cities: Judicial Responses through the Lens of Sustainability Transformations
Authors: Gill Gitanjali Nain
Published: April 2024

Cities and urban communities constitute a challenging paradox. They are contributors to climate change and simultaneously are essential focal bases for economic activity. Urbanization, population growth, economic development, and prosperity contribute to increased city greenhouse gas emissions. Envisioning and shaping a shift toward more ambitious climate responses is both an opportunity and a challenge for cities to action transformations toward sustainability. The discourse on sustainability transformations involves the reorientation and restructuring of governance processes and actions. Though the governance of transformation involves multiple actors, this article examines the role of the Indian judiciary in steering a transformation process toward a sustainable and equitable future. Indian city-and-climate-change case law is examined as a case study. Sectoral examples from construction, waste, livestock, transport, and renewable energy illustrate key areas addressed through the judicial incremental-reformist approach. Bolstering the implementation and enforcement of environmental and climate laws alongside the infusion of a powerful sustainability agenda, the Indian judiciary creates enabling conditions for transformational change.
Fact and Fiction in the Dubai cop’s Decision on Fossil Fuels
Authors: Zahar Alexander
Published: April 2024

The flagship decision of the 28th Conference of the Parties to the United Nations Framework Convention on Climate Change, issued on 13 December 2023, appears to call for the elimination of fossil fuels. This would be a first in the annals of the international legal regime on climate change. In reality, I argue, while the decision acknowledges that the world must move away from fossil fuels, it concedes that there is no known practical way of doing so. The combined effect of these positions is the same as the understanding which states had settled on prior to the Dubai conference, namely that each state would work at its own self-determined pace to reduce its reliance on fossil fuels.
Crime, culture or war? Justifying military responses to violence against civilians
Authors: Vorland Holen Sine
Published: April 2024

Interpreting violence against civilians is necessary for eliciting appropriate protection responses, yet the structuration processes through which military personnel make sense of observed violence are underexplored. This article draws on the experiences of Norwegian military officers, applying Boltanski and Thévenot's theory of justification to investigate how officers discern violence targeting unarmed individuals and justify their reactions. Although they frequently categorize violence into ‘war’, ‘crime’ and ‘culture’, employing civic, industrial and humanitarian logic structures, officers grapple with the realities that transcend such neat classifications. Rooted in the sociology of justification and violence, this article provides insights into how actors navigate plural violence in conflict and their struggles in making justifiable decisions that ultimately prepare the ground for action to take place.

Published: April 2024

The walking blood bank (WBB) is a system for emergency blood acquisition from nearby donors if a patient’s blood needs exceed the immediate supply. USCENTCOM medical units will perform a walking blood bank if immediate blood requirements exceed the local supply. A benchmark WBB performance time was needed to provide a training goal for military WBB exercises. An expeditionary WBB performance time benchmark was created from prospective measurements of USCENTCOM medical unit performance times over 9 months. The mean total time, and new performance benchmark, for a WBB in USCENTCOM was 41.4 min +/− 13.2 min. USCENTCOM time from donor arrival to a transfusable unit mean time was 34.4 +/− 12.1 min. Expeditionary medical units conducting a WBB should expect to meet or exceed the provided benchmark.
From Bytes to Best Practices: Tracing ChatGPT-3.5’s Evolution and Alignment With the National Comprehensive Cancer Network® Guidelines in Pancreatic Adenocarcinoma Management
Authors: Bresler Tamir E. , Pandya Shivam , Meyer Ryan , Htway Zin , Fujita Manabu
Published: April 2024

Introduction

Artificial intelligence continues to play an increasingly important role in modern health care. ChatGPT-3.5 (OpenAI, San Francisco, CA) has gained attention for its potential impact in this domain.

Objective

To explore the role of ChatGPT-3.5 in guiding clinical decision-making specifically in the context of pancreatic adenocarcinoma and to assess its growth over a period of time.

Participants

We reviewed the National Comprehensive Cancer Network® (NCCN) Clinical Practice Guidelines for the Management of Pancreatic Adenocarcinoma and formulated a complex clinical question for each decision-making page. ChatGPT-3.5 was queried in a reproducible fashion. We scored answers on the following Likert scale: 5) Correct; 4) Correct, with missing information requiring clarification; 3) Correct, but unable to complete answer; 2) Partially incorrect; 1) Absolutely incorrect. We repeated this protocol at 3-months. Score frequencies were compared, and subgroup analysis was conducted on Correctness (defined as scores 1-2 vs 3-5) and Accuracy (scores 1-3 vs 4-5).

Results

In total, 50-pages of the NCCN Guidelines® were analyzed, generating 50 complex clinical questions. On subgroup analysis, the percentage of Acceptable answers improved from 60% to 76%. The score improvement was statistically significant (Mann-Whitney U-test; Mean Rank = 44.52 vs 56.48, P = .027).

Conclusion

ChatGPT-3.5 represents an interesting but limited tool for assistance in clinical decision-making. We demonstrate that the platform evolved, and its responses to our standardized questions improved over a relatively short period (3-months). Future research is needed to determine the validity of this tool for this clinical application.
The Past, Present, and Future of Research on Mathematical Giftedness: A Bibliometric Analysis
Authors: Özdemir Atilla , Sipahi Yasemin , Bahar A. Kadir
Published: April 2024

There is a well-established historical background of research on mathematical giftedness that can be traced back to the early 1900s. An overarching purpose of this research was to review and explore the existing research and its evolution since its emergence in educational and psychological studies. Thus, we examined the past, present, and future of research on mathematical giftedness using a bibliometric analysis. Our findings provided extensive insights into the intellectual structure of the extant literature on mathematical giftedness, including the leading journals, articles, countries, authors, institutions, and networks among researchers as well as key research topics that were investigated in the literature. Perhaps one of the most striking findings of this study was about the productivity in the field over the years as the bibliometric analysis indicated a decline in the number of publications that were published in the last several years. We discussed possible factors behind the recession in research investigations on mathematical giftedness and provided significant implications of the findings to inform future research.

Published: April 2024

Improvements in race times for male and female Para canoe athletes across different sports classes have led to a reduction in relative differences between classes over time. However, there is a lack of research examining the comparative developmental trajectories between high-performance Paralympic (PCS) and Olympic (OCS) canoe sprint. In this study, we compared the developmental trajectories of 200-meter kayak performances among PCS and OCS athletes. In total, we analyzed 628 race results obtained from public online databases, for nine competitions between 2015 and 2023. Race times were reduced over the years except in specific sports classes (KL3-M, K1-M, and K1-F; KL: Kayak Level, M: male, F: female), with a poor positive correlation (r = 0.17 to 0.33) between time and the years. For the remaining sports classes, these correlations ranged from poor to fair (r = −0.58 to −0.13). OCS K1 athletes outperformed their Paralympic counterparts. Among Paralympic classes, KL1 had slower times than KL2 and KL3 ( p ≤ .05), with KL2 times significantly lower than KL3 in the female category. OCS athletes exhibited less variability in race times compared to PCS athletes. In the male category, there were no significant differences in the coefficients of variation (CV) and amplitude of race times between sport classes, except for KL1-M, which had a larger CV than K1 ( p ≤ .05). In the female category, the CV and amplitude of race times were significantly higher in KL1-F compared to KL3-F and K1-F. OCS times remained stable from 2015, with KL3-M following a similar trend. PCS displayed greater race time variability, particularly in higher impairment classes, notably KL1. This underscores the existence of distinct developmental stages within the canoe sprint modality, particularly emphasizing the early developmental phase of KL1. It also provides valuable insights for coaches and sports selection, especially concerning athletes with more severe impairments, including those in Rehabilitation Centers and during athlete recruitment.
A BaTiO3@polyacrylonitrile/poly(vinylidene fluoride) nanofibrous composite membrane with high piezoelectricity based on the central combination design method and cross-electrospinning technology
Authors: Yang Bo , Zhang Xifeng , Tang Jiakang , Zhu Xinyu , Hao Ming , Hu Xiaodong , Liu Yanbo
Published: April 2024

The rapid development of piezoelectric sensors has been studied extensively, owing to their good flexibility, wearability, high sensitivity and low cost. However, some inorganic materials with good piezoelectricity cannot make sensors flexible, and the organic materials with good flexibility have a weak output electrical signal and low strength. In order to explore and optimize the preparation technology of piezoelectric sensors, a BaTiO3@polyacrylonitrile (PAN)/poly(vinylidene fluoride) (PVDF) nanofibrous composite membrane (NCM) was prepared by cross-electrospinning technology and the central combination design (CCD) method. The morphology, structure, hydrophobicity, mechanical properties and piezoelectricity of the BaTiO3@PAN/PVDF NCMs were investigated. The BaTiO3@PAN/PVDF NCMs had the better hydrophobicity and mechanical properties compared with the pure PAN/PVDF NCM. The 5BaTiO3@PAN/PVDF NCM designed by CCD had a more uniform fiber diameter, and a more stable output voltage with a 46% improvement. With the help of cross-electrospinning technology and the CCD method, the NCM will be outstanding for the development of fabricating flexible wearable piezoelectric sensors.

Published: April 2024

Community nurses play a key role in providing continuous home care for patients with chronic diseases. However, a perfect system of responsibilities and requirements has not yet been formed, and nurses cannot provide high-quality nursing services for home-based patients. We attempted to construct an index of the scope of practice for community nurses providing home-based transitional care for patients with chronic diseases and to guide nurses in playing an active role in transitional care work. From March to May 2023, 14 representative community nurses from the Shanghai Community Health Service Center were selected for group interviews and 2 rounds of Delphi consultation. A total of 14 valid questionnaires were collected. The authority coefficients were 0.94 and 0.93, and the Kendall coefficients were 0.56 and 0.59 for the 2 rounds of expert consultation ( P < .05). Finally, an index system, including 6 primary indices (transitional caring provider, patient self-management facilitator, community group intervention organizer, home caregiver supporter, family physician team collaborator and supervisor of home medical equipment use, and medical waste disposal) was constructed for community nurses involved in providing home-based transitional care for patients with chronic diseases. The weight values of the 6 indices were 0.19, 0.17, 0.21, 0.13, 0.14 and 0.16, respectively (CR = 0.035, and the consistency test was passed), and 16 secondary indicators and 42 tertiary indicators were identified. In this Delphi study, an index system that can be used to determine community nurses’ roles in providing home-based transitional and continuous care for patients with chronic diseases was successfully established. The index system is considered reliable and easy to use and will provide a meaningful reference for community nurses and policy-makers.
Memorability of Romanian dissidence: Ordinary people, secret files and artistic remediations
Authors: Mitroiu Simona , Mironescu Andreea
Published: April 2024

The article explores the conditions necessary for a narrative recounting of past events to become memorable and incorporated into collective memory. The analysis is focused on the role played by artistic remediations in creating such memorability. In Romania, as well as in other East Central European countries, the production of memorability and the management of the resulting collective memories are interlinked with the narratives of communism that dominate the memorialisation of the recent past. The article reviews several examples of acts of dissent, based on their representativeness and the existing literature, and question the memorability of dissident acts by considering the memory discourse on communism and the involvement of different agents of memory. It also interrogates the use of the Romanian secret police (Securitate) files in artistic productions, examining this acknowledgement of the role played by the Securitate in creating the narratives of the communist past. Two artistic productions based on reworkings of the Securitate files are analysed: a documentary theatre play staged by Gianina Cărbunariu, Uppercase Print (2013), and Radu Jude’s 2020 film of the same title, both presenting the story of Mugur Călinescu. The article argues that these productions question mainstream frames of memory by revisiting the narratives and biographies created by the Securitate files and give new, artistically mediated voices to victims, perpetrators and collaborators.
A macro-nationalist periodical for a new Europe? Franco-Italian exchanges and Latin Renaissance in Cronache della civiltà elleno-latina (1902–1907)
Authors: Nemegeer Guylian
Published: April 2024

This article focuses on the discourse on pacifism and Latinity in the Italian periodical Cronache della civiltà elleno-latina (1902–1907), founded by Angelo De Gubernatis. Under the leadership of Crispi in the 1880s and 1890s, Italy embraced expansionism, colonialism, and pro-German attitudes, which strained its relations with France. In stark contrast to this militarism, the Cronache championed a vision of Italy rooted in liberal and democratic ideals. The periodical advocated for a peaceful international order to enhance Italy’s position in modernity. In doing so, it proposed an anti-belligerent macro-nationalism based on the dissemination of the values of Latinity: harmony, peace, and order. Specifically, I analyze how the periodical used the historical relations between France and Italy to construct a myth of a new Latin Renaissance. This Renaissance envisioned a profound epochal transformation, a new beginning in European history characterized by peace, unity, and solidarity among Europe’s nations.
Passing By: Zarathustra’s Other Response to Revenge
Authors: Satkunanandan Shalini
Published: April 2024

Nietzsche’s On the Genealogy of Morality warns that revenge’s reactiveness can jeopardize salutary change in shared values. I identify an overlooked revenge-mitigating praxis in the spatial movements of Nietzsche’s fictional prophet Zarathustra, who seeks collaborators to overcome Christian morality and create new world-affirming values. Zarathustra’s well-known response to revenge, specifically the revenge against time undergirding interpersonal revenge, is willing the eternal return of the same. But he also exemplifies a more available response. “Passing by” is a coming close to, followed by a veering away from, the most insistent embodiments of reigning values. Although Nietzsche inspires agonistic political theory, Zarathustra avoids direct contest in the usual late modern milieux, which he finds constitutively vulnerable to revenge. When revenge floods the communal passional reservoir, it forestalls recovery—essential to new-values creation—of passions effaced by reigning values. Zarathustra still approaches the usual milieux to know the present-past as the raw material of the future. But by then veering away he practices relaxing his value-creative will and not raging against the present-past. Repeated passing by helps him accept and thus better take up the raw material of the future and accept value change’s slow temporality. Since passing by’s concern is the value horizon, not the political sphere, and since it minimizes direct resistance, it may be less reactive to the political sphere than directly contestatory versions of “refusal.” Analysis of Gandhi’s value-praxis confirms passing by as a tactic for less reactive value-creation and as a lens on the reactiveness of different value-praxes.
Turkish Military Sociology: Exploring the Evolution of an Early Starter but Latecomer
Authors: Ateş Barış
Published: April 2024

This article explores the reasons for the late development of Turkish military sociology. Although the relationship between the Turkish military and society has some unique characteristics, it has received little attention from sociologists. The existing literature primarily focuses on the narrow field of civil-military relations conducted by political scientists and includes minimal sociological research on the military. Based on historical analysis using primary and secondary sources and interviews, this shortcoming is due to the politicization of sociology and even equating it with communism, the denial of research permits due to bureaucratic secrecy, the sacred position of the military in the eyes of society, and the partial apathy of Turkish sociologists. The institutionalization of Turkish military sociology after the 2016 coup attempt is promising, but restrictions on research permits remain challenging for its future. Building a solid military sociology literature without critically assessing the existing research would also be problematic.
“I See Her Able to Stay on Track”: How School Structures Shape Elementary Teachers’ Reported Characterizations and Supports for Students in Mathematics
Authors: Franke Megan , Lee Juliet , Roberts Christine
Published: April 2024

Background or Context:

Teachers knowing their students is consequential for students’ participation and learning. Evidence in mathematics education points to the ways that knowing the details of students’ mathematical thinking supports teacher and student learning. What it means to know students and what teachers learn about their students are situated in the everyday practices of schooling.

Purpose, Objective, Research Question, or Focus of Study:

This study investigates how teachers characterized their students mathematically and how they considered meeting students’ needs in math class.

Research Design:

This qualitative study focused on interviews conducted over four years with 61 teachers of kindergarten through second grade across two school districts.

Conclusions or Recommendations:

This study found that rather than describing what they knew about the details of their students’ mathematical thinking or detailing specific tasks, tools, or teacher moves that supported their students, many teachers characterized students in ways that were in line with practices that organize districts, schools, and classrooms. Our data raise questions about the ways in which the structures and common practices of schools are shaping teachers’ descriptions of their students in mathematics, and the corresponding classroom practices then engaged.
Sequential Mediation Effects of Organizational Support and Collaboration on Missed Nursing Care
Authors: Kang Yeon-Ji , Uhm Ju-Yeon
Published: April 2024

Background:

It is necessary to find ways to mediate the relationship between role overload and missed nursing care in settings where nursing staffing is inadequate. This study aimed to identify the single and multiple sequential mediation effects of organizational support, nurse-physician collaboration, and nurse-nurse collaboration on the relationship between role overload and missed nursing care.

Methods:

Data were collected from 237 registered Korean nurses working in general wards in October 2022. The measures used were the modified role overload scale, nurse-physician collaboration scale, nurse-nurse collaboration scale, a short version of the Perceived Organizational Support Scale, and the modified Missed Nursing Care Scale. Data were analyzed using PROCESS macro in SPSS. A hypothesis test was performed using Model 81, proposed by Hayes, which includes serial multiple mediators.

Results:

Organizational support, nurse-physician collaboration, and nurse-nurse collaboration showed a mediation effect on missed nursing care. Organizational support, nurse-physician collaboration, and nurse-nurse collaboration showed significant multiple sequential mediation effects on the relationship between role overload and missed nursing care. When the indirect effect sizes of nurse-physician collaboration were compared with those of nurse-nurse collaboration in both single and multiple sequential mediation paths, the indirect effect of nurse-physician collaboration was greater than that of nurse-nurse collaboration on the relationship between role overload and missed nursing care.

Conclusions:

As an alternative strategy to reduce missed nursing care in situations with insufficient nursing staffing, organizational support should precede nurse-physician and nurse-nurse collaboration. In particular, improving nurse-physician collaboration shows promise in mitigating missed nursing care.

Authors: Causey Chandler , Jones Elisabeth , Califano Michaela , Curtis Abby , Muir Justin , Dauch William , Dell’Aiera Laura , Fitzgerald David
Published: April 2024

Introduction

Simulation-based learning has become an essential element in entry-level perfusion education. While the use of simulation has been demonstrated to improve patient outcomes, few institutions possess the budgetary resources to build and maintain a high-fidelity simulation environment. This project aims to identify novel uses of web conferencing platforms to support in-person, remote, and virtual simulation exercises.

Methods

The Zoom Virtual Meeting platform (Zoom Video Communications, Inc.) was incorporated into the perfusion simulation curriculum at the Medical University of South Carolina CVP Program. Among the observed benefits of incorporating meeting platform software included high-definition audio/visual outputs and recording capabilities, 3-D remote simulation, remote simulation proctoring, and classroom-based learning. Additional Zoom features included remote controlled screen access and sharing, annotations, and break-out rooms and activities.

Conclusion

The combination of high-fidelity simulation with virtual and remote features may enhance the learning experience in healthcare education. Future developments in technology and software, simulation education, and instructions through virtual/remote learning may provide a pathway for the future of cardiovascular perfusion education.
Validating the Ego-Resiliency Questionnaire for Preadolescents (the ER-P) Using a Population-Based Sample From Korea
Authors: Kim Yeon Ha
Published: April 2024

This study aimed to introduce an ego-resiliency questionnaire for preadolescents (the ER-P) by restructuring the ER89 using the data of 1398 preadolescents from the Panel Study on Korean Children. The ER-P was proposed as a 10-item second-order instrument with two factors (Optimal Regulation and Openness to Life Experiences). The ER-P achieved configural, metric, and scalar levels of measurement invariance across gender. The ER-P scores exhibited correlations with personality traits of the five-factor model and general happiness, providing evidence of its convergent validity. This suggests that the ER-P has sound psychometric properties for evaluating ego-resiliency in Korean preadolescents. The validation of the ego-resiliency questionnaire specifically tailored for younger individuals marks a significant expansion of the ego-resiliency research domain, especially considering that existing instruments were initially designed for adults. The ER-P will be useful in education, counseling, and research settings that require information on preadolescents’ self-rated inner strength.

All four first premolar extraction treatments were planned with simultaneous retraction and intrusion of maxillary and mandibular dentition. The case was treated using 022 slot MBT prescription appliance. Lip exercises were prescribed to increase the tone of lips, which would aid in attainment of lip seal. Case was completed with class I molars, normal overjet–overbite, and improved smile aesthetics. The patient exhibited competent lips and reduced anterior–posterior gingival show.
Wind tunnel tests of a two-bladed Savonius wind rotor with novel parabolic blades
Authors: Mohan Man , Saha Ujjwal K
Published: April 2024

The study presents an experimental research on a vertical-axis Savonius wind rotor featuring optimized parabolic blades. This parabolic blade is developed by optimizing its sectional cut-angle through a series of numerical simulation. The parabolic-bladed Savonius rotor of various aspect ratios is tested in a low-speed wind tunnel to evaluate its power coefficient ( CP) along with its self-starting capability. For a direct comparison, the tests are also conducted for a rotor with the semicircular blades. The wind tunnel tests demonstrate the peak CP of the parabolic and conventional semicircular bladed rotors to be 0.165 and 0.138, respectively at a tip-speed ratio of 0.67 and an aspect ratio of 0.9. The wind rotor with the parabolic blades shows an improvement of CP by 19.56% against its conventional semicircular counterpart. With the inclusion of blockage correction, the test rotors with parabolic and semicircular blades show the CP of 0.161 and 0.134, respectively.

This multicentre, retrospective medical record audit evaluated opioid analgesia prescribing within a Victorian metropolitan public hospital network. The study included all surgical patients discharged between January 2012 and December 2020 with one or more discharge prescriptions from three metropolitan hospitals ( n = 117,989). The main outcome measures were mean oral morphine equivalent daily dose (OMEDD), mean number of opioid types and proportion of patients prescribed one or more slow-release opioids on discharge.

Total opioid prescribing (mean OMEDD) peaked in 2013. Between 2017 and 2020 there was a trend towards prescribing fewer opioids on discharge. Over the study period, there was decreasing prescription of codeine and increasing prescription of oxycodone and tapentadol. The proportion of patients prescribed slow-release opioids increased in the earlier years of the study, reaching a peak of 20.6% in 2017. Since 2017 there has been a rapid reduction in the prescription of slow-release opioids.

Subanalysis was undertaken to evaluate key changes in the opioid prescribing landscape in the health network. The removal of default opioid pack sizes in the electronic medication management system (December 2014) and the release of the Faculty of Pain Medicine–Australian and New Zealand College of Anaesthetists’ statement regarding the use of opioid analgesics in patients with chronic non-cancer pain (March 2018) were associated with significant reductions in mean OMEDD prescribed on discharge (136 mg vs 122 mg and 120 mg vs 85.4 mg, respectively, P < 0.001).

In conclusion, the quantity of opioids prescribed on discharge in this patient group peaked in 2013 and has been decreasing since.
Professionalisation of financial planning in Australia, Canada, and South Africa

Delivery of apt financial advice to the public has become a high priority in developed countries due to the increased complexity of personal finance. Using the theory of professionalisation and qualitative interviews, we investigate the common barriers that three apex financial planning professional bodies encounter as they create a jurisdiction for Certified Financial Planners® (CFP). We show that a sales orientation, commission-based remuneration, membership entrenchment with financial product providers and other stakeholder lobbying impede the professional bodies’ progress. However, governmental willingness to regulate financial advice, coupled with technological advances, may enable professionalisation. Our article adds to research on the professionalisation of financial planning and offers practical insights into how other bodies around the world can progress CFP’s jurisdiction. Our research differs from the published work on other professions because it is happening even as we write.

Introduction

Effectiveness of candesartan in migraine prevention is supported by two randomized controlled trials. We aimed to assess the effectiveness, tolerability, and response predictors of candesartan in the preventive treatment of migraine.

Methods

Observational, multicenter, prospective cohort study. The 50%, 75% and 30% responder rates, between weeks 8–12 and 20–24, were compared with the baseline. Treatment emergent adverse effects were systematically evaluated. Response predictors were estimated by multivariate regression models.

Results

Eighty-six patients were included, 79.1% females, aged 39.5 (inter-quartile range [IQR] 26.3–50.3), with chronic migraine (43.0%), medication overuse headache (55.8%) and a median of two (inter-quartile range: 0.75–3) prior preventive treatments. At baseline patients had 14 (10–24) headache and 8 (5–11) migraine days per month. The 30%, 50% and 75% responder rates were 40%, 34.9% and 15.1% between weeks 8–12, and 48.8%, 36%, and 18.6% between weeks 20–24. Adverse effects were reported by 30 (34.9%) and 13 (15.1%) patients between weeks 0–12 and 12–24, leading to discontinuation in 15 (17.4%) patients. Chronic migraine, depression, headache days per month, medication overuse headache, and daily headache at baseline predicted the response between weeks 20–24.

Conclusion

Candesartan effectiveness and tolerability in migraine prevention was in line with the clinical trials’ efficacy. Trial registration: The study protocol is registered in ClinicalTrials.gov (NCT04138316).
Physical impairment during and between migraine attacks: A daily diary study of patients with chronic migraine

Objective

While a substantial body of research describes the disabling impacts of migraine attacks, less research has described the impacts of migraine on physical functioning between migraine attacks. The objective of this study is to describe physical impairment during and between migraine attacks as a dimension of burden experienced by people living with chronic migraine.

Methods

The physical impairment domain of the Migraine Physical Function Impact Diary was recorded in headache diaries from the Medication Overuse Treatment Strategy trial. Days with moderate to severe headache were used to approximate migraine attacks. Factor analysis and regression analysis were used to describe associations between migraine and physical impairment.

Results

77,662 headache diary entries from 720 participants were analyzed, including 25,414 days with moderate to severe headache, 19,149 days with mild headache, and 33,099 days with no headache. Mean physical impairment score was 41.5 (SD = 26.1) on days with moderate to severe headache, 12.8 (SD = 15.0) on days with mild headache, and 5.2 (SD = 13.1) on days with no headache. Physical impairment on days with mild headache and days with no headache was significantly associated with days since last moderate to severe headache, physical impairment with last moderate to severe headache, mild headache (compared to no headache), depression, hypersensitivities and cranial autonomic symptoms.

Conclusions

Physical impairment occurs on migraine and non-migraine days. Study participants with frequent headaches, symptoms of depression, hypersensitivities and cranial autonomic symptoms experience physical impairment at a higher rate on days with no headache and days with mild headache.

Portraying Political Ideas of National Revolutionaries: A Case Study of Pandurang Mahadev Bapat
Authors: Singh Shri Prakash , Barthwal Prashant
Published: April 2024

The term ‘revolutionary’ has a unique connotation in India’s struggle for national liberation. It refers to those freedom fighters who scrupulously believed in the efficacy of armed resistance to overthrow British rule in India and justified employing extremist techniques to achieve the objective. Consequently, national revolutionism creates a distinct stream of thinking in the Indian national movement from both the moderate and extremist currents in the movement. While there is no end to the literature on both moderate and extremist thinking in British India, the political philosophy of the revolutionaries has not been satisfactorily addressed by academia in a meaningful manner. While there are a few notable exceptions, social scientists in India have generally ignored the revolutionary political ideas because of the foundation of British authority over Indian land; the nation’s political development began to follow a pattern identical to the Western development model. Following that, some extensive Western influences were seen in education, economy, government organisation and administration, significantly impacting the intellectual development of the time.

Moreover, the ideas of revolutionaries were, for the most part, immediate intellectual responses to the political challenges and crises that existed at the time of their birth. However, some of these topics were significant, such as formulating a critique of British imperialism, defining the national identity, reorganising Indian society and developing plans for national liberation. As a result, it will be necessary to examine and evaluate the political views of these revolutionaries in the context of the concerns and problems with which they were confronted at the time. This research explores and explains Bapat’s political thought and situates him in Maharashtra’s revolutionary and Hindu political traditions. Lastly, in the first instance, this research proposes a brief look at the development of Bapat’s political career, which played a vital role in shaping his political ideas. Then, it explores the significant politics of colonial and post-colonial times.
