Dose of selective serotonin reuptake inhibitors and risk of upper gastrointestinal bleeding in older adults
Authors: Li Yu-Hsien , Hang Liang-Wen , Muo Chih-Hsin , Chen Sheng-Jen , Chen Pei-Chun
Published: December 2023

Background:

Selective serotonin reuptake inhibitors (SSRIs) have been associated with an increased risk of upper gastrointestinal bleeding (UGIB) in older patients but little is known about the risk associated with individual SSRI drugs and doses.

Aims:

To quantify the risk of UGIB in relation to individual SSRI use in older adults.

Methods:

We conducted a nested case–control study within a cohort of 9565 patients aged ⩾65 years prescribed SSRIs from 2000 to 2013 using claims data of universal health insurance in Taiwan. Incident cases of UGIB during the follow-up period were identified and matched with three control subjects. Conditional logistic regression was used to estimate the odds ratio (OR) of UGIB associated with individual SSRI use and cumulative dose.

Results:

UGIB risk increased with the increasing cumulative doses of SSRIs (adjusted OR: 1.28, 95% confidence interval (CI): 1.02–1.62 for the highest vs. the lowest tertile). Compared with users of other SSRIs, fluoxetine users were at an increased risk of UGIB (adjusted OR: 1.25, 95% CI: 1.03–1.50) with a dose–response manner, whereas paroxetine users had 29% decreased odds (95% CI: 0.56–0.91). The increased risk was only observed among current fluoxetine users.

Conclusions:

Fluoxetine therapy was associated with an increased risk of UGIB in a dose–response manner among older adults.
Bringing labor back: Financialized inclusion and survival struggles in the periphery of the periphery
Authors: Siqueira Erica Souza , Fontenelle Isleide Arruda
Published: December 2023

This article examines how financial platforms address the value realization crisis within contemporary capitalism in “the periphery of the periphery.” Drawing from Marxist political economy, particularly in the context of its interpretation in peripheral spaces, we empirically studied the introduction of a digital microcredit platform in the living and working space-time of informal workers in Brazil’s periphery. Expanding on the household financialization literature, we scrutinize how this organization extracts value directly from living labor. Through dialectical analysis, we investigate how informal workers fearfully adhere to microcredit while cultivating invisibility practices, constituting forms of resistance against the advance of the microcredit platform. These workers’ labor-life narratives illustrate how credit adherence, while alluring, poses a threat to transform their lives, not only by leading to indebtedness but also by exposing the survival practices that enable their precarious existence on the fringes of the system, which we term “survival struggles.” These struggles manifest in the blurred boundaries between the center and the periphery, as well as between production and reproduction, creating an intersection between the concepts of survival and boundary struggles.
Reappraisal of stratigraphic position of a sandstone included in the Bagh Formation, exposed near Belam Bujurg, Khargone District, Madhya Pradesh, India

Published: December 2023

A sandstone included in the Bagh Formation occurs at Belam Bujurg, District Khargone, Madhya Pradesh. Its stratigraphic position is controversial. Bose considered it as Nimar Sandstone. His observation, that it is capped by a limestone containing bryozoans, implies that Sitapuri Bryozoan Limestone directly overlies Nimar Sandstone at Belam Bujurg. However, it is contradictory to Chiplonkar’s (1982) observation that Nodular limestone is invariably associated with Nimar Sandstone. According to Roy Chowdhury and Sastri (1954, 1958), this sandstone is an intercalation within the Sitapuri Bryozoan Limestone. Later, Badve (1987) correlated this sandstone with Nimar Sandstone on the basis of similar ichnofauna and believed that overlying limestone cap represented calcareous facies coming at the top of Nimar Sandstone. However, elsewhere frequency and variety of trace fossils are distinctly more in limestone layers, in comparison to sandstone layers. Moreover, the presence of similar trace fossils indicates similarity in the conditions of deposition, rather than correlation. Recent fieldwork by the present authors corroborates that this sandstone is an intercalation within Sitapuri Bryozoan Limestone. Identification of the bryozoan Limestone was confirmed by petrographic study in thin section.
Shells, Fronts, Astroturfing, and Beyond: Examining Concealment Strategies of Proxy Organizations
Authors: Scott Craig R. , Kang Katie K.
Published: December 2023

This study investigates what we call proxy organizations (e.g., shell companies, front organizations, astroturfing efforts). Drawing on existing literature to better conceptualize proxy organizations and their communicative nature, we position these proxy organizations within scholarship on visibility management and hidden organizing. To answer research questions about public discourse around these proxies and their use of concealment strategies, we analyze news coverage of these organizations from 2001, 2011, and 2021. Findings suggest sizable increases in discourse about each proxy type. Additionally, analysis reveals several concealment themes in that media coverage: dark/secret money/finances, hidden owners, shadowy influence, anonymous proxies, covert links, online concealment, secret/illegal activities, and revelation safety/fear. We then draw conclusions, discuss implications, and suggest directions for future organizational communication research about proxy organizations.
The Fragmented Labor Power Composition of Gig Workers: Entrepreneurial Tendency and the Heterogeneous Production of Difference
Authors: Maury Olivia
Published: December 2023

The literature on digital labor platforms requires a focus beyond techno-utopianism, foregrounding the role of living labor that materially sustains the fantasies of convenience ingrained in platform capitalism. The gig workers embodying living labor exhausted by location-dependent platform work are mainly migrants. Yet, greater understanding of the complexity of difference production and the gigification of work is needed. The article is prompted by the desire to understand the relationship between entrepreneurialized workers and heterogeneously produced differences within the labor power composition of gig workers active on location-based labor platforms. Drawing on ethnographic data produced together with migrant workers engaged in food delivery and cleaning gigs via labor platforms in Helsinki, the article first analyzes the organizing logic of gig work mediated via platforms through the notion of transversal entrepreneurial tendency, and second, the entwined forms of social, legal, and algorithmic difference produced among gig workers. The article argues that differentiation in labor power composition is dynamically related to the interactions required and facilitated by the platforms. The article contributes to discussions on entrepreneurialization in the contemporary world of work and the specific ways in which the social, legal, and algorithmic production of difference shape the constitutive hierarchies of platform labor.
Brokering collaborations between academia and the creative economies in Africa through creative imagination workshops
Authors: Kibuchi Waithera , Ogungbe Folakemi , Madyibi Vuyolwethu
Published: December 2023

Africa’s creative industries are increasingly receiving attention due to their potential to generate human and economic growth and development. Converting this potential into tangible and sustainable development requires consistent collaboration between higher education (HE) institutions and the creative economy. This case study reflects on the role of Creative Imagination Workshops (CIWs) in brokering collaboration between HE and selected creative sectors in Kenya, Nigeria, and South Africa. The CIWs were an initial phase of the African Hub for Sustainable Creative Economies (AHSCE) research project. They aimed to support network building and collaboration by providing online exchange and networking opportunities. Workshop participants were recruited through both formal and informal networking processes. The CIWs demonstrate that intermediaries such as the AHSCE can offer virtual ‘third spaces’ which feature little to no financial barrier to entry, encouraging academics and entrepreneurs to engage with each other, and facilitating the exchange of knowledge and resources. While the virtual workshop delivery model precipitates high levels of attendance and engagement, it is vulnerable to limitations in national infrastructure. Generating enough trust to transform connections initiated virtually into collaborative in-person partnerships also requires an extended timetable or a hybrid model combining virtual and physical interactions.
A Response to the Question of Pride and Prejudice in Stacey Floyd-Thomas's ‘Forgive Us Our Trespasses’
Authors: Phillips Victoria
Published: December 2023

Dr. Floyd-Thomas’s paper brings nuance to the discussion of pride and the hubris brought by the Westernized Enlightenment across disciplines. As much as I have the impulse to throttle others or shout or spit with the onslaught of mis-truths and ‘alternative facts’, this would not be a wise moment to conclude inquiry as an oral historian, or a Christian ethicist. I ask, can we decolonize ourselves, our syllabi, the canon, and thus our students with grace, understanding, even forgiveness so as not to repeat the trespasses?
Expert patients leading activities on social justice: towards patient-centered education
Authors: Feijoo-Cid Maria , Arreciado Marañón Antonia , Fernández-Cano María Isabel , García-Sierra Rosa María
Published: December 2023

Background

Social justice is recognized by reputable international organizations as a professional nursing value. However, there are serious doubts as to whether it is embodied in Catalan nursing education.

Objectives

To explore what nursing students take away from two teaching activities led by expert patients (one presentation and three expert patient illness narratives) on the topics of social justice, patient rights, and person-centered care.

Research design

Qualitative study using a content analysis approach. The research plan included (1) think-pair-share activities (additional faculty-assisted presentation and three faculty-assisted, semi-structured scripted narratives); (2) paired reflections; (3) focus groups; and (4) content analysis of paired reflections and focus groups.

Participants and research context

Fourth-year nursing degree students at the Autonomous University of Barcelona (UAB), Spain. Convenience sampling was used.

Ethical considerations

The UAB Research Ethics Committee did not deem it necessary to apply any specific measures. We fully explained to patients that they could decide what medical information they would share with the students that was relevant to their learning, and we provided students with guidelines about patient confidentiality, dignity, and respect.

Findings/results

The students engaged in reflection about their education (recognizing that it had been centered on the professional and not the patient) and their relationship with the patient, in which they reproduced low-involvement patient care by modeling behaviors of their nurse educator. Moreover, they valued a person-centered care model with an emphasis on the emotional part but left out decision-making as an individual right of people.

Conclusions

The think-pair-share activities were useful to spark self-reflection among students, who identified aspects to change in their own practice, and reflected about their own education process, both of which promote change.

Authors: Rash Isabelle , Shi Kevin , Sussel Robyn , Smith Richard , Thompson Spencer , Cai Edward , Nguyen Tu Dat , Cheng Julia , Gong Wenyi , Farahmand Sahar , Mehrnoush Vahid , Hosseinzadeh Shahriar , Qayumi Karim
Published: December 2023

Background

In the hospital, interprofessional team members must work collaboratively. That creates a gap in medical practice, particularly in a hectic emergency that may lead to medical errors, with associated ethical, legal, and financial consequences. Mannequin-based simulation can be a solution to bridge this gap in team training. While mannequin-based simulations are effective as a synchronous method, they are expensive, time and space-bound, use hospital resources, and require the whole team to be present.

Objective

To develop a prototype of a 3D virtual simulation emergency room (ER) environment for interprofessional team training. And to assess the usability of the prototype in a simulation environment for team training using a clinical scenario.

Methods

Tools and technologies used for this prototype included the Unity platform, C# programming language, and Photon Voice 2. With 3DS Max, we modified and created 3d assets in the ER simulation room. Adobe XD was used to create interactive prototype iterations. Clinical cases were developed with simple algorithms to prove the concepts. We used complex algorithms with Artificial Intelligence and Machine Learning capabilities for the final product. We conducted two usability tests (n = 10, n = 9) using a think-aloud method, a semi-structured follow-up interview, and a survey.

Results

A prototype was built to achieve asynchronous team training with easy user access from anywhere in the world. The prototype, which includes voice communication and control of the avatars by players from a distance, supported the usability of the technology for asynchronous team training in health education.

Conclusions

CyberPatientER can be used as an additional tool to support team training and communication skills in the health education and healthcare environment.
Emotions and Narrative Reappraisal Strategies of Users of Breast Cancer Screening: Reconstructing the Past, Passing Through the Present, and Predicting Emotions
Authors: Martino Maria Luisa , Lemmo Daniela , Donizzetti Anna Rosa , Bianchi Marcella , Freda Maria Francesca , Caso Daniela
Published: December 2023

Emotional forecasting, meaning how a person anticipates feeling as a consequence of their choices, drives healthcare decision-making. Research, however, suggests that people often do not fully anticipate or otherwise grasp the future emotional impacts of their decisions. Emotional reappraisal strategies, such as putting emotions into words and sharing emotions with others, may mitigate potential undesirable effects of emotions on decision-making. The use of such strategies is important for consequential decisions, such as obtaining timely mammography screening for breast cancer, whereby earlier diagnosis may impact the success of treatment. In this study, we explored the use of emotional reappraisal strategies for decision-making regarding breast cancer screening attendance among women aged 50–69 years. Data were collected through semi-structured interviews following mammography with a reflexive thematic methodological approach employed for analysis. Results shed light on how participants’ emotional response narratives were reconstructed before the mammography, felt during the mammography, and forecasted while awaiting the results. Future research should consider how individuals experience and manage their emotions as they access breast screening services.
Narrative Medicine in Hospice and Palliative Care: A Longitudinal Fellowship Curriculum Pilot
Authors: Paul Trisha K. , Aglio Taylor , Dalgo Austin , Kaye Erica C.
Published: December 2023

Introduction

Growing evidence suggests that clinician exposure to narrative medicine (NM) may help bolster resilience and mitigate burnout. The value of formal longitudinal training in NM for hospice and palliative medicine (HPM) trainees remains understudied.

Methods

A 1-year longitudinal NM curriculum for HPM fellows was pilot-tested for feasibility, acceptability, and exploratory impact. Six monthly 45-minute sessions included reading literature, reflective writing, and sharing creative work. Quantitative and qualitative data were collected through a pre-intervention survey and post-intervention survey administered immediately upon completion of the curriculum. Longitudinal impact was assessed with a post-intervention survey administered three months after completion of the curriculum.

Results

All HPM fellows (n = 6) attended at least 5/6 sessions during the 1-year pilot, suggesting intervention feasibility. Participant engagement and self-reported comfort with NM exercises supported intervention acceptability. Post-intervention, participants described the positive influence of NM practice on their clinical practice and stated an intention to integrate NM skills in their future HPM careers. Three months following the intervention, participants had a sustained increase in their comfort level with NM. All participants felt that the NM sessions had been relevant to their life as HPM fellows and anticipated using NM moving forward in their practice of HPM.

Discussion

This novel NM curriculum was feasible and acceptable to implement in a 1-year HPM fellowship. Longitudinal impact showed sustained increase in trainee comfort and interest in using NM in their future clinical practice.
Cross working condition bearing fault diagnosis based on the combination of multimodal network and entropy conditional domain adversarial network
Authors: Feng Yuanpeng , Liu Peng , Du Yixian , Jiang Zhansi
Published: December 2023

In the realm of intelligent fault diagnosis, fault diagnosis methods based on deep learning have been widely used and have achieved tremendous success. However, traditional single-modal fault diagnosis methods face challenges in terms of accuracy and reliability under conditions such as noise interference. To address this issue, this paper proposes a cross working condition rolling bearing fault diagnosis method based on the combination of multimodal network and entropy conditional domain adversarial network (ECDAN). Firstly, the time-domain signal is transformed into a time–frequency matrix through continuous wavelet transform (CWT), and then a deep feature extraction network is designed. This network integrates convolutional neural network (CNN) and 2D-ResNet18 to extract features from both time-domain signals and time–frequency matrices, and fuses these features. In order to enhance the transferability of learning features, the adversarial strategy of ECDAN is utilized to ensure alignment of bearing sample data between the source and target domains. Experimental validation on bearing dataset from the comprehensive fault simulation test platform for machinery demonstrates the effectiveness of the proposed method, indicating its capability to handle complex and variable working conditions as well as noise interference.
The Emergence of Virtual Experiences in the Sharing Economy
Authors: Hwang YooHee , Shin Seunghun , Kim Taekyung
Published: December 2023

Virtual travel experiences are increasing in various online platforms. In peer-to-peer platforms, people can even sell and buy virtual experiences (e.g., touring attractions virtually and personalizing trip itineraries). With a fresh theoretical lens of Touchpoints, Context, and Qualities of customer experience design, this study unpacks important attributes of virtual experiences in the sharing economy. Using a multi-method approach, this study identifies important attributes of virtual experiences and experience hosts using regression (Study 1) and conjoint (Study 2) analyses. As a result, the average rating of reviews about a virtual experience is the most important attribute, followed by the number of selling points, number of images, time length of the virtual experience, and the host’s use of intuitive and plain words. The current study extends the customer experience design literature and provides implications of virtual experiences in the sharing economy to hospitality and tourism businesses.
Where were you when Facebook went out? Experiences of involuntary disconnection from social media
Authors: Andersson Linus , Danielsson Martin
Published: December 2023

This paper presents findings from an online questionnaire that collected experiences from the Facebook outage on October 4th, 2021, an event that affected approximately three billion users around the globe. The purpose of the study is to contribute to recent discussions digital disconnection and digital wellbeing by using an extraordinary event of involuntary disconnection as point of departure. Our research questions were: Where were people when the services shut down, what did they think and what did they do? What correlations can be found between usage/attitudes to social media and the experiences of the outage? How can the outage of October 4th be understood as a snapshot of our cultural condition? The questionnaire was distributed to 463 Swedish university students and 191 responses were received. Our analysis shows how the involuntary disconnection caused by the outage was an event that highlights the ambivalence of digital life. It also points to some correlations between general social media use and attitudes, and the experiences and activities during the outage. The paper ends with a discussion on the implications that these findings may have for further research into digital disconnection.
Strategic adjustments: Daily experiences of lesbian, gay, bisexual, transgender, queer, and intersex persons in Nairobi
Authors: Divon Shai André , Vestlie Ann W , Jessen Reidar S
Published: December 2023

Despite International efforts by NGOs and social movements to protect lesbian, gay, bisexual, transgender, queer, and intersex (LGBTQI) people in Africa, they still face injustices, stigma, and discrimination. This study uses an assemblage approach to analyze narratives collected through interviews with LGBTQI individuals in Nairobi, Kenya about the daily strategies they use to navigate the tensions between their need for livelihood security, personal safety, and their gender and sexual identity. The study employs the analysis of daily experiences to discuss how contexts and preferences interact with internal sexual identities and choices for external expressions of sexual identities.
On the use of notes and note-taking in social science: A study of private writing
Authors: Swedberg Richard
Published: December 2023

This paper has two main goals: to make an exploratory study of the use of notes and note-taking in social science, with a special emphasis on sociology, and to suggest a few ways in which this practice can be improved. By note-taking is here meant the writing of notes to observe, to remember, and to work and think with. It is suggested that most forms of note-taking represent a kind of private writing, in the sense that the notes are written exclusively for the writer and not for other people to read as in public writing. The quality of being private changes the structure as well as the content of the note which is often hard to understand for others. The approach in the paper is historical as well as material. Early forms of note-taking by social scientists are discussed, and also its use today in such areas as fieldwork, participant observation and qualitative sociology. The paper concludes with a discussion of a few ways in which the note-taking practices in social science can be improved.
The discourse of the Anthropocene and posthumanism: Indigenous peoples and local communities
Authors: Dovchin Sender , Dovchin Ulemj , Gower Graeme
Published: December 2023

Indigenous peoples and local communities (IPLCs) are characterised by their special relationships with their traditional lands and the natural world, which are essential to their physical and cultural survival, identity, knowledge, and spirituality. They are custodians of the land; however, often made invisible and voiceless in the face of irreversible destruction caused by human-induced planetary change. This Special Issue (SI) is inspired by the stories, worldviews, knowledge systems, and lived experiences of IPLCs worldwide. Based on the compounded impacts of global climate change and other human-induced crises on IPLCs’ ancestral lands, contributors to this SI recognise that the world has entered the Anthropocene – the epoch of human-induced planetary change. While human activities are considered geologically recent, they have profoundly impacted the planet. The contributors challenge the discourse of the Anthropocene, not only because it takes humanity as the prime reference point in understanding the world but also because of its reproduction of the onto-epistemological foundations of Eurocentric philosophy, which underpins colonialism and racial capitalism. This SI opens up space for historically marginalised IPLCs’ cosmologies, which embody their holistic, spiritually and physically interconnected, interdependent, and reciprocal relationships with land, the natural world, and non-human beings. It expands and pluralises the discourse of the Anthropocene through the concept of posthumanism to recognise alternative knowledge systems that decentre humanity’s dominant position in understanding the world. IPLCs’ onto-epistemologies align with posthuman or more-than-human ways of knowing, being, and doing, which embody their reciprocal relationships with land, non-human beings, and the natural world that are all deemed as living entities with agency. IPLCs’ voices urge us to relearn our ancestral ways of understanding and interacting with the world and reconnect to our holistic relationships with the planet Earth and its beings to ensure the continuity of nature and culture.
Using text-to-image generation for architectural design ideation
Authors: Paananen Ville , Oppenlaender Jonas , Visuri Aku
Published: December 2023

Text-to-image generation has become very popular in various domains requiring creativity. This article investigates the potential of text-to-image generators in supporting creativity during the early stages of the architectural design process. We conducted a laboratory study with 17 architecture students, who developed a concept for a culture center using three popular text-to-image generators: Midjourney, Stable Diffusion, and DALL-E. Through standardized questionnaires and group interviews, we found that image generation could be a meaningful part of the design process when design constraints are carefully considered. Generative tools support serendipitous discovery of ideas and an imaginative mindset, enriching the design process. We identified several challenges of image generators and provided considerations for software development and educators to support creativity and emphasize designers’ imaginative mindset. By understanding the limitations and potential of text-to-image generators, architects and designers can leverage this technology in their design process and education, facilitating innovation and effective communication of concepts.
Frank O’Connor’s “Guests of the Nation”: A Civil War Story of Brother Against Brother?
Authors: Grant John
Published: December 2023

This article argues that one of Ireland’s literary greats Frank O’Connor (1903–1966) utilized the Irish War of Independence (WOI) as a backdrop for “Guests of the Nation,” one of the most famous works about the Irish revolutionary period. The 1931 short story is set during the Irish WOI (1919–1921). This essay, however, wishes to explore the notion that a subsequent but separate conflict—the Irish Civil War (1922–1923)—was at the forefront of O’Connor’s mind at the time of writing, with concepts of duty, brotherhood, and the questioning of hegemonic military codes suggesting the Civil War undercurrent throughout. Although the cast of characters presented in the story includes two captured English soldiers, Belcher and Hawkins (as well as their Irish captors Bonaparte—the narrator—Noble, and Jeremiah Donovan), the cottage and its inhabitants function, for the writer, as a literary prop that acts as a free landscape to create a “better world.” This, it is argued here, allowed O’Connor to articulate his primary thoughts around the societal influences formed during the Civil War, a conflict of which, in contrast to the WOI, the writer had direct experience.

Authors: Yoosefi Lebni Javad , Irandoost Seyed Fahim , Torabi Ali , Saki Mandana , Ahmadi Ahmad , Mehedi Nafiul
Published: December 2023

The COVID-19 pandemic has caused new conditions, problems, and different research platforms for qualitative research. The aim of the present study was to analyse the challenges and opportunities facing qualitative researchers during the COVID-19 pandemic in Iran. This qualitative research was conducted with a conventional content analysis approach with twenty-four Iranian health sciences researchers. The participants were selected by snowball and purposive sampling. Data collection was carried out using semi-structured face-to-face and online interviews until reaching saturation. Data analysis was also carried out using the Graneheim & Lundman approach in MAXQDA-2018 software, and to improve the trustworthiness of the results, Guba and Lincoln’s criteria were used. Data analysis led to the identification of two main categories, 13 subcategories, and 69 primary codes: The challenges were in areas such as data collection methods, access to participants and how to conduct interviews. Opportunities also included formation of new topics for qualitative research, highlighting the importance of qualitative research, strengthening the technological knowledge of researchers, research cost-effectiveness, and presenting further information on sensitive topics. It is also possible to strengthen qualitative research by supporting qualitative researchers at universities and research centres, facilitating the administrative processes, providing communication infrastructure such as suitable Internet in universities, ensuring more diversity in data collection methods, developing an appropriate protocol during the COVID-19 pandemic, and dedicating some university rooms to qualitative researchers to conduct interviews.
Longitudinal and azimuthal thermo-acoustic instabilities in an industrial gas turbine combustor operating at elevated pressure
Authors: Fredrich Daniel , Jones William P , Marquis Andrew J , Bulat Ghenadie
Published: December 2023

This work numerically investigates longitudinal and azimuthal thermo-acoustic instabilities in the swirl-stabilised can-type industrial SGT-100 gas turbine combustor operated at elevated pressures of 3 and 6 bar. Previous experiments have shown that the combustor is susceptible to self-excited flame oscillations sustained by a thermo-acoustic feedback loop at specific operating conditions. In order to gain a better understanding of this feedback loop, a fully compressible large eddy simulation method is applied. The unknown sub-grid scale turbulence-chemistry interactions are modelled via a transported probability density function approach solved by the Eulerian stochastic fields method. First, the reaction zones and global flame topology at both operating pressures are analysed and compared to experimental images providing good qualitative agreement. Radial profiles of time-averaged and root-mean-square quantities furthermore demonstrate good quantitative agreement with the available measurement data. The applied simulation approach is capable of successfully reproducing self-excited thermo-acoustic instabilities in the longitudinal direction. The fundamental frequency of the predicted limit-cycle oscillation matches the experimentally measured frequency with high accuracy. Similar to the experimental observations, the fluctuation amplitudes of the pressure and global heat release rate increase significantly upon increasing the mean operating pressure from 3 to 6 bar. In addition to the dominant longitudinal mode, a high-frequency, low-amplitude azimuthal mode is also identified at both pressures. This azimuthal mode is periodically amplified and attenuated by the superposed longitudinal mode and induces small asymmetric (around the burner circumference) fluctuations of the local fuel and total mixture mass flow rates entering the flame region.
How Teachers Make Decisions in Response to Professional Learning: A Study on Grade 3 Differentiation in Mathematics
Authors: Cody Rachael A. , Boldt Gregory T. , Gubbins E. Jean
Published: December 2023

This study used a mixed-methods design to examine teachers’ responses to professional learning on mathematics differentiation. Grade 3 classroom teachers ( N = 28) attended four 2-h professional learning sessions and an additional 2 h individually on differentiation and completed pre- and post-surveys with quantitative and short response items assessing their experiences. Although teachers did not report changes in overall differentiation rates, implementation of less extensive practices (i.e., talk moves and mathematical practices) increased. Changes did not appear to be driven by teachers’ valuation of differentiation, which was high across surveys. Rather, a thematic analysis indicated that teachers simultaneously weighed benefits, challenges, and alignment with existing practices when making decisions about whether to implement differentiation strategies.

Authors: Moore Zonía Robenne , Zajdman-Faitelson Dalit , Campillo Arely Tamariz , Brito Bustillos Diana Karen , Toussaint-Caire Sonia , Berumen-Glinz Cristina
Published: December 2023

Nivolumab (PD-1 inhibitor) and ipilumumab (CTLA-4 inhibitor) are recently approved checkpoint inhibitors for treatment of non-small cell lung cancer. Immune-related adverse events related to the usage of checkpoint inhibitors are growing with their popularity. We present the case of a patient in combination treatment of nivolumab and ipilimumab who developed a lichenoid drug reaction, notable because it worsened to a bullous lichenoid drug reaction. Treatment with prednisone and withdrawal of checkpoint inhibitors aided in clinical resolution. Initial presentation of a lichenoid reaction that progressed to a bullous, desquamated presentation indicates the possibility of the prodromal rash progressing to a Stevens-Johnson Syndrome-like dermatosis. When dermatologists are consulted for rashes developed during checkpoint-inhibitor therapy, they should be aware that early treatment may prevent progression to bullae formation and desquamation and develop their treatment plans with this in mind.
Principals’ Transformational Leadership and Kindergarten Teachers’ Career Calling: The Mediating Roles of Organizational Identification and Leader-Member Exchange
Authors: Li Feifei , Jiao Runkai , Liu Dan , Liu Lili
Published: December 2023

Perceiving a calling toward one’s career can provide kindergarten teachers sufficient internal motivation to resist massive job burnout and obtain high-level performance and well-being. Given the important role of leadership on followers’ career calling, the present study takes the multilevel approach to examine the cross-level impact of team-level transformational leadership (TFL) of principals on the individual-level career calling of kindergarten teachers. Moreover, according to the identity-capability-reward (ICR) model, the present study investigates the mediating effects of kindergarten teachers’ organizational identification and leader-member exchange (LMX) from the social identity and social exchange perspectives to explain why TFL could positively predict kindergarten teachers’ career calling. Data were collected from 486 teachers at 57 kindergartens in China. Applying the multilevel analysis, results showed that principals’ TFL could positively predict kindergarten teachers’ sense of career calling, in which teachers’ organizational identification and exchange quality with principals played the full mediating effects. These findings extend previous studies and provide practical implications to enhance kindergarten teachers’ career calling.
Understanding Emerging Adults’ Perspectives on Mental Health in Togo
Authors: Zolnikov Tara Rava , Kodjo Ezui Florian , Furio Frances , Clark Tanya , Chambers Deborah
Published: December 2023

Mental health worldwide is extremely important to address; unfortunately, many aspects of mental health are not visibly known or treated in the world. Moreover, some developmental groups are more affected than others; in fact, emerging adulthood is a crucial developmental phase that is prone to depression. With most mental health conditions beginning before the age of 24 and depression as the leading cause of disability globally, this study sought to identify emerging adults’ understanding of depression, a common disease among this population. A qualitative study was used to understand depression during emerging adulthood in Togo. There were 35 participants recruited for this study. With the growing younger population in Sub-Saharan Africa projected to double in a decade and the dearth of studies in the mental health field on the continent, this study serves as a foundation for research into emerging adults’ mental health. Like most countries in Sub-Saharan Africa, the inexistence of a stand-alone mental health program, the shortage of qualified mental health professionals, and insufficient civil society education on mental health problems remain the fundamental barriers to accessible care in Togo. As the study indicated, there are many ways to provide new opportunities for emerging adults to self-educate about mental health. By increasing our understanding of depression among emerging adults, the findings of this research study offer valuable data as a foundation not only for future studies, but also for mental health policy development and targeted programming for emerging adults in Sub-Saharan Africa and Togo in particular.

Background:

Anterior cruciate ligament reconstruction (ACLR) surgery with quadriceps tendon (QT) grafts, both with and without a patellar bone plug, have gained popularity in recent years in the primary and revision settings. Postoperative complications occur with the use of QT autografts.

Purpose:

To systematically review the incidence of postoperative complications after primary ACLR QT autograft and compare complication rates in patients undergoing all-soft tissue QT grafts versus QT grafts with a patellar bone plug (QTPB).

Study Design:

Systematic review; Level of evidence, 4.

Methods:

A literature search using the 2020 PRISMA guidelines was performed by querying PubMed, Embase, and Scopus databases from database inception through August 2022. Included were evidence level 1 to 4 human clinical studies in English that reported complications after primary ACLR with QT autograft. The incidence of complications within the included studies was extracted. Differences in the incidence of postoperative complications between ACLR with QT with and without a patellar bone plug were calculated.

Results:

A total of 20 studies from 2004 to 2022, comprised of 2381 patients (2389 knees; 68.3% male) with a mean age of 27 years (range, 12-58 years), were identified. The mean follow-up was 28.5 months (range, 6-47 months). The total incidence of complications was 10.3%, with persistent postoperative knee pain being the most common (10.8%). Patients who underwent ACLR with all-soft tissue QT grafts had a 2.7-times increased incidence of anterior knee pain (23.3% vs 8.6%) and reoperations (5.9% vs 3.2%) when compared with QTPB grafts ( P < .01 for both). There was no appreciable difference in total complications, graft failures, ACLR revisions, cyclops lesions, or range of motion deficit ( P > .05 for all). Patellar fractures occurred exclusively after QTPB (2.2%).

Conclusion:

Complications after primary ACLR using QT autograft were recorded in 10.5% of knees, with anterior knee pain being the most common. No difference was reported in the overall incidence of complications with the use of the QT versus QTPB grafts; however, anterior knee pain was 2.7 times greater with use of a soft tissue quadriceps graft.
LGBTQ Identities and Career Plan Changes in Young Adulthood: Implications for Occupational Segregation and Disparities

Many young adults change their career plans after spending some time in the labor force, and those who hold marginalized identities change their plans in unique ways as they respond to unfair treatments in workplaces. Past research on this topic focused on (cisgender) women and people of color, and little is known about how LGBTQ people change their career plans. Furthermore, many LGBTQ youth today develop optimistic views that their sexual and gender identities will not undermine their career opportunities, but the existing literature provides limited information about whether they maintain such views after their transition to the labor force and how they change their career plans if their perceptions of career disadvantages change. To fill these gaps in the literature, the authors analyzed longitudinal data from in-depth interviews with 37 LGBTQ young adults, who were followed over 2 to 10 years at 2-year intervals. The data showed that young LGBTQ workers’ career plan changes were intertwined with their sexual and gender identities. For example, some participants decided to move to more LGBTQ-friendly careers after experiencing workplace harassment and heteronormativity and cisnormativity, and those who had entered careers that allowed them to integrate their LGBTQ identities into work decided to leave the careers because of emotional burnout. Overall, the results suggest that LGBTQ people’s career plan adjustments to identity-related challenges at work operate as a worker-level mechanism that contributes to labor market segregation and financial disparities between LGBTQ and straight, cisgender workers.

Research shows that questionable research practices (QRPs) are present in undergraduate final-year dissertation projects. One entry-level Open Science practice proposed to mitigate QRPs is “study preregistration,” through which researchers outline their research questions, design, method, and analysis plans before data collection and/or analysis. In this study, we aimed to empirically test the effectiveness of preregistration as a pedagogic tool in undergraduate dissertations using a quasi-experimental design. A total of 89 UK psychology students were recruited, including students who preregistered their empirical quantitative dissertation ( n = 52; experimental group) and students who did not ( n = 37; control group). Attitudes toward statistics, acceptance of QRPs, and perceived understanding of Open Science were measured both before and after dissertation completion. Exploratory measures included capability, opportunity, and motivation to engage with preregistration, measured at Time 1 only. This study was conducted as a Registered Report; Stage 1 protocol: https://osf.io/9hjbw (date of in-principle acceptance: September 21, 2021). Study preregistration did not significantly affect attitudes toward statistics or acceptance of QRPs. However, students who preregistered reported greater perceived understanding of Open Science concepts from Time 1 to Time 2 compared with students who did not preregister. Exploratory analyses indicated that students who preregistered reported significantly greater capability, opportunity, and motivation to preregister. Qualitative responses revealed that preregistration was perceived to improve clarity and organization of the dissertation, prevent QRPs, and promote rigor. Disadvantages and barriers included time, perceived rigidity, and need for training. These results contribute to discussions surrounding embedding Open Science principles into research training.
Embodying intercultural communicative competence in French L2 video reflections: Illustrating skills, knowledge, and attitudes
Authors: Gorham Julia A , Amgott Natalie
Published: December 2023

Research has long touted and recently confirmed the importance of intercultural communicative competence (ICC) — the ability to appropriately communicate with those from diverse sociocultural and linguistic backgrounds — in second language (L2) teaching and learning. Additionally, while multimodal course materials have contributed to learners’ ICC, the link between students’ embodied modes (gestures, facial expressions, body movements) and ICC remains under-explored. Building on ICC and the social semiotic theory of multimodality, this study blends multimodal transcription and conversation analysis to examine how 73 university undergraduate learners of L2 French used embodied modes in 188 asynchronous video reflections and how these modes accompanied demonstrations of ICC skills, knowledge, and attitudes. Findings indicate that gestures and facial expressions indicated students’ demonstrations of the ICC skills of observing, analyzing/interpreting, evaluating, relating, listening, questioning, researching, and problematizing. Further, embodied modes demonstrated students’ retrieval and communication of cultural and sociolinguistic knowledge. This study has implications for online language learning and enhancing ICC through virtual multimodal assignments.
