Green initiatives towards environmental sustainability: Insights from libraries in Kenya
Authors: Mwanzu Arnold , Bosire-Ogechi Emily , Odero Damaris
Published: February 2023

Environmental protection is an increasingly pressing issue all over the world. Ozone depletion, the greenhouse effect, global climate change and global warming are among the rising environmental concerns. The increasing number of environmentally conscious consumers has resulted in numerous Go Green campaigns and a Go Green movement, along with solutions and calls for consumers, corporations and governments to be more proactive in going green in every aspect. Libraries are no exception. Although it is so important, little is known about the green-library concept in the African context and among Kenyan libraries. Like some other developing countries, Kenya has responded to climate change in various ways because of its adverse impacts. It is important to explore how libraries are planning for a sustainable future. Subsequently, this study aimed to explore the adoption of green-library concepts in Kenya for environmental sustainability with a view to proposing strategies that can be used to guide libraries in going green. The study adopted a qualitative approach. A sample of 12 libraries was purposively drawn from a population of 227 academic, public and special libraries in Kenya. Data was collected using semi-structured interview schedules complemented by observation and a document review, and analysed using grounded theory. The findings show that libraries in Kenya, under their umbrella organizations, have taken advantage of their knowledge of green concepts through adopting and implementing green practices and coming up with strategies to enhance green libraries and promote environmental sustainability. They have done this mainly through redesigning and renovating to meet ever-changing user demands in line with green-library standards. The study concludes that librarians in Kenyan libraries understand green-building concepts and have adopted different green initiatives, albeit partially to reposition and maintain their position globally. The study proposes three strategies for fully going green: active user involvement in green initiatives; improving performance and growth measuring metrics; and maintaining green-library standards in accordance with the IFLA’s Environment, Sustainability and Libraries Section (ENSULIB) green-library checklist.

Published: February 2023

Background:

Nonrigid fixation techniques have been recently introduced in free bone block (FBB) procedures to treat substantial glenoid bone loss in patients with anterior shoulder instability. However, the radiological and histological effectiveness of nonrigid fixation versus conventional rigid fixation have not been comprehensively understood in vivo.

Purpose:

To (1) explore the radiological and histological characteristics of nonrigid fixation for FBB procedures in a rabbit model of glenoid defects and (2) further compare them with those of conventional rigid fixation.

Study Design:

Controlled laboratory study.

Methods:

Unilateral shoulder glenoid defects were created in 36 mature New Zealand White rabbits, of which 24 underwent FBB procedures using allogenic iliac crest bone and were randomly divided into rigid fixation (RF) and nonrigid fixation (N-RF) groups, with the remaining divided into 2 control groups: 6 with sham surgery for glenoid defects (GD group) and 6 native glenoids (normal group). In the RF and N-RF groups, 6 rabbits were sacrificed at 6 or 12 weeks postoperatively for radiological and histological analyses of the reconstructed glenoid, and all rabbits in the GD and normal groups were sacrificed at 12 weeks. The radiological glenoid morphology was evaluated via micro–computed tomography. Moreover, the graft-glenoid healing and graft remodeling processes were determined using histological staining.

Results:

At 6 weeks, both the N-RF and RF groups had similarly improved radiological axial radian and en face area of the glenoid compared with the GD group, but the N-RF group showed superiority in restoration of the glenoid radian and area compared with the RF group at 12 weeks, with the native glenoid as the baseline. Histologically, the bone graft in both groups was substantively integrated into the deficient glenoid neck at 6 and 12 weeks, showing similar osseous healing processes at the graft-glenoid junction. Moreover, the bone graft histologically presented similar regenerated vascular density, total graft bone, and integrated graft bone in both groups. In contrast, the N-RF group had a different remodeling profile on radiological and histological analyses regarding regional bone resorption, mineralization, and fibrous tissue replacement during osseointegration.

Conclusion:

Compared with rigid fixation, nonrigid fixation resulted in superior reconstructed glenoid morphology radiologically and similar graft-glenoid osseous healing histologically, showing different graft remodeling profiles of regional bone resorption, mineralization, and fibrous tissue replacement.

Clinical Relevance:

The nonrigid fixation technique can be feasible for FBB procedures to treat glenoid bone loss in anterior shoulder instability. More clinical evidence is required to determine its pros and cons compared with conventional rigid fixation.
Historical Argumentation: Watching Historians and Teaching Youth
Authors: Nokes Jeffery D. , De La Paz Susan
Published: February 2023

In this article, we explore the uniqueness of argumentation within the field of history, considering whether historians’ processes in crafting an interpretive argument from inexact evidence might provide insights into processes vital for informed civic engagement and civil dialogue in democratic societies. We discuss the role of argumentation in history, taking both historian (expert) and student (novice) perspectives by considering what historical writing is and how it is produced, taught, and learned. Unlike other research on argumentative historical processes, we examine the role of dispositions that complement skills and enrich collaborations as historians grapple with historical problems together. We examine the role that dispositions and historical thinking skills play as students discuss evidence, plan for argumentative writing, and evaluate their peers’ ideas. We propose that the dispositions and skills involved in historians’ reading, writing, and thinking parallel the critical thinking needed for deliberative and collaborative reasoning about complex social issues. Finally, we explore how instruction and experience with deliberative collaboration within historical problem spaces may prepare students for meaningful civic engagement. We call for increased research on these potential connections.
Cooperative optimal guidance of hypersonic glide vehicles by real-time optimization and deep learning
Authors: Li Yaxuan , Liu Xinfu , He Xinhua , Zhang Fubiao
Published: February 2023

This paper investigates the cooperative optimal guidance of hypersonic glide vehicles (HGVs) in the terminal phase with consideration on time-varying velocity, aerodynamic forces, and practical constraints. The cooperative optimal guidance problem is formulated as an optimal control problem with time as the independent variable, which brings great convenience in controlling the impact time. We propose proper convexification techniques to convexify this problem and apply successive convex optimization to get the solution of the original problem. To achieve cooperative guidance of multiple HGVs with time coordination constraint, a deep learning–based approach is proposed to find an optimal common impact time assigned to all the HGVs. The training samples required by deep learning are obtained by convex optimization. An algorithm is then presented to summarize the cooperative optimal guidance strategy. In each guidance loop, the common impact time is updated according to mission conditions, and the guidance commands are generated by the successive solution procedure in real time. Numerical examples will be provided to demonstrate that the proposed cooperative optimal guidance algorithm is effective and efficient, and it can achieve better performance than a popular cooperative proportional navigation guidance law.
Life Detection From Biological Motion
Authors: Troje Nikolaus F. , Chang Dorita H. F.
Published: February 2023

Life motion, the active movements of people and other animals, contains a wealth of information that is potentially accessible to the visual system of an observer. Biological-motion point-light displays have been widely used to study both the information contained in life motion stimuli and the visual mechanisms that make use of it. Biological motion conveys motion-mediated dynamic shape, which in turn can be used for identification and recognition of the agent, but it also contains local visual invariants that humans and other animals use as a general detection system that signals the presence of other agents in the visual environment. Here, we review recent research on behavioral, neurophysiological, and genetic aspects of this life-detection system and discuss its functional significance in the light of earlier hypotheses.

Commentary: Is Australian headspace socioculturally westernised, educated, industrialised, rich and democratic in conceptualisation and accessibility?
Authors: Looi Jeffrey CL , Kisely Stephen R , Bastiampillai Tarun , Allison Stephen
Published: February 2023

Objective

The Australian headspace model has been proposed as an internationally significant exemplar for reducing the mental health ‘treatment gap’ amongst young people around the world. We provide a commentary that discusses the conceptualisation and delivery of headspace services within Australia, a predominantly Westernised, Educated, Industrialised, Rich and Democratic (WEIRD) society, as well as examining accessibility and suitability for culturally and linguistically diverse (CALD) communities.

Conclusion

headspace was conceptualised, designed, implemented and evaluated according in a WEIRD sociocultural context, and is therefore most applicable to that setting. Australia also has CALD communities, who have not seemed to access headspace in the reported patient and staff demographics. On this basis, there may be questions about the potential generalisability of headspace models outside WEIRD societies.
The prevelance of psychosis in indigenous populations in Australia: A review of the literature using systematic methods
Authors: Jewell James , Mitchell David
Published: February 2023

Objectives

To understand the prevalence of psychosis in Aboriginal and Torres Strait Islander populations.

Methods

A systematic review of the literature was conducted using PubMed, Embase and Cochrane.

Results

Eight studies were reviewed. The prevalence of psychosis appeared higher in Aboriginal and Torres Strait Islanders, compared with non-Aboriginal and Torres Strait Islander populations.

Conclusion

Although the literature suggests the prevalence of psychosis in Aboriginal and Torres Strait Islander populations is substantial, there are few studies and limited scope. Cultural competency is essential to understanding psychosis in this context.
The Use of Flexible Work Arrangements: Examining Experiences of Perceived Backlash Through the Lens of Diversity
Authors: Lee Hyun Jung , Probst Tahira M. , Bettac Erica L. , Jenkins Melissa R. , Bazzoli Andrea
Published: February 2023

As more businesses have newly adopted or expanded flexible work arrangements (FWA) due to the COVID-19 pandemic, the current study aimed to investigate whether flexibility backlash (e.g., workers’ negative perceptions of promotion opportunities and work-to-life conflict) occurs in response to the use of FWA. Moreover, we tested if perceptions of flexibility backlash vary across subgroups of employees (i.e., as a function of gender, family responsibilities, and race), as well as their intersection. Using a lagged dataset of N = 414 currently employed U.S. workers collected at three-time points during the early stages of the COVID-19 pandemic, we found that FWA use was not significantly associated with the subsequent perception of career opportunities, and no group differences were found in this relationship. Similarly, no main effect of FWA use on work-to-life conflict was found. However, among workers with more family care responsibilities, greater FWA usage was associated with more work-to-life conflict. Further, intersectionality analyses revealed men with greater family responsibilities and men who are racial minorities perceived more work-to-life conflict as they used more FWA than their counterparts. We discuss these findings through the lens of diversity in light of the ongoing need to reduce the backlash associated with the use of FWA.
The Predictive Validity of Item Effect Variables in the Satisfaction With Life Scale for Psychological and Physical Health
Authors: Sengewald Marie-Ann , Erhardt Tina H. , Gnambs Timo
Published: February 2023

Although the Satisfaction with Life Scale strives to capture a single dimension, describing respondents’ satisfaction with life as a whole, individual items might also capture unique aspects of life satisfaction leading to some form of multidimensionality. Such systematic item-specific variance can be viewed as a content-laden secondary trait. Information on the nomological net and predictive validity can be useful to aid the interpretation of these item-specific effects. Therefore, the present study on N = 2,543 Dutch respondents adopts revised latent state-trait theory to disentangle common construct variance, random measurement error, and person-specific item effects in the Satisfaction with Life Scale across three measurement occasions. The reported analyses not only demonstrate how to examine item-specific multidimensionality in longitudinal data but also emphasize how different identification constraints for the latent variable lead to different interpretations. Moreover, the predictive validity of item effect variables for the prediction of psychological and physical health is examined. A cross-validation with the same sample at a later measurement period and robustness checks with incomplete data, support our findings on the substantive value of a multidimensional specification of the Satisfaction with Life Scale for substantive analyses. Finally, the contributions of person-specific item effects for psychological assessments are discussed.
Vibro-acoustic response of ribbed-panel-cavity systems due to an internal sound source excitation
Authors: Zhang Kai , Pan Jie , Lin Tian Ran , Guo Hui , Zhang Baocheng
Published: February 2023

An analytical solution is presented in this study for the vibro-acoustic analysis of a cavity coupled with a ribbed panel due to an internal point sound source excitation. The solution is validated by comparing the result with that obtained using finite element analysis. Generally good agreements are found between the results. The model is then used to examine the sound transmission either through a single ribbed–panel or multiple ribbed–panels separated by air gaps. Results demonstrate that the rib enhancement is effective to reduce the energy transmission controlled by the panel control modes. Whereas the attenuation of the energy transmission to the panels is more effective for the cavity control modes when multiple ribbed panels with air gaps are used. The result also shows that the depth of the air gaps will also play a part on the sound attenuation across the panel system where a larger air gap will lead to a better sound attenuation.
Argon laser trabeculoplasty for congenital ectropion uveae: Case report and review of the literature
Authors: Incandela Cosimo , Ferreri Paolo , Sisto Dario , Alessio Giovanni
Published: February 2023

A 18-year-old woman with unilateral glaucoma secondary to congenital ectropion uveae (CEU) in the right eye, without other systemic and ocular associations. Intraocular pressure (IOP) was uncontrolled under topical therapy. The visual field (VF) was within normal limits; retinal nerve fiber layer (RNFL) thickness, as evaluated by Optical Coherence Tomography (OCT), was reduced. The patient refused surgical intervention. After evaluation of the iridocorneal angle, ALT was performed as follows: 95 spots were applied for the 270 ° of visible trabecular meshwork using a laser beam diameter of 50 μm, an exposure time of 0.1 s and a power of 750 mw). Mean IOP in the right eye, as evaluated by diurnal tonometric curve, was 10 mmHg, 16 mmHg and 20 mmHg respectively one month, four months and eight months after ALT, with no additional topical therapy, and 18 mmHg twelve months after ALT with topical therapy. CEU is a rare, non-progressive anomaly characterized by the proliferation of iris pigment epithelium on anterior surface of iris; glaucoma, in this disorder, is often poorly controlled with medical therapy alone. In a phase of initial glaucomatous damage and with a not particularly high IOP, as in this case, ALT could be an alternative therapeutic option at least in the short-term, when surgery is not feasible immediately. In fact, given its limited effectiveness over time, ALT can be used as a temporary control measure of IOP, pending surgery to become feasible.
US-guided central venous catheter placement in the neonatal intensive care unit: Brachiocephalic vein or internal jugular vein?
Authors: Osman Dere , Mehmet Kolu , Halil Kazanasmaz
Published: February 2023

Background:

Centrally inserted central catheters (CICCs) are commonly used to monitor venous pressure and administer parenteral nutrition and drugs in newborns. In the present study, we evaluated cannulation success rates, cannulation time, and frequency of complications in catheterization of the internal jugular vein (IJV) and brachiocephalic vein (BCV).

Methods:

The present study included patients who underwent IJV and BCV catheterization under ultrasound (US) guidance. The patients were divided into two groups, IJV and BCV, depending on the vein in which the CICC was utilized. We documented the diameters of the IJVs and BCVs, first attempt and overall success rates, mean cannulation time, and complication rates.

Results:

A total of 79 patients were evaluated, 37 in the BCV group and 42 in the IJV group. No significant differences were observed between the two groups in terms of sex, mean age, or weight range ( p > 0.05).The mean vein diameter was significantly larger in the BCV group than in the IJV group ( p < 0.001); the mean number of attempts was significantly higher in the IJV group than in the BCV group ( p < 0.001); the mean cannulation time was significantly longer in the IJV group than in the BCV group ( p < 0.001); and the first attempt success rate was 50% in the IJV group, versus 94.6% in the BCV group. The overall success rate was 100% in both groups. The rate of complications was 8.6% in the IJV group, while no complications developed in the BCV group.

Conclusions:

Given the larger diameter of the vessel, BCV catheterization was found to result in quicker cannulation and lower complication rates. The results of the present study suggest that BCV catheterization should be the first choice for neonatal intensive care unit (NICU) patients who require parenteral support or close venous pressure monitoring.

Authors: Prasad Raghunandan , Vignesh Selvamurugan , Yadav Rajanikant R , Sharma Srishti , Hasani Prerna , Yadav Tanya , Israrahmed Amrin , Lal Hira
Published: February 2023

Introduction:

Thrombosed arteriovenous fistulas (AVFs) are either treated by thrombectomy or pharmaco-mechanical thrombolysis with or without percutaneous balloon angioplasty. In this study, we have described an effective and economical technique of salvaging these fistulae using a 20–22-gauge spinal needle and urokinase and have named it direct percutaneous thrombolysis (DPT).

Materials and method:

This prospective study comprised of 148 patients out of which 120 patients presented with AVF thrombosis and were divided into two groups; those with no obvious stenosis on ultrasound ( n = 38) and second with venous stenosis ( n = 82). Remaining 28 patients developed thrombosis post angioplasty for venous stenosis. Percutaneous injection of urokinase into the thrombus was done under ultrasound guidance, followed by balloon angioplasty if there was associated stenosis.

Results:

In 38 patients who didn’t have any stenosis, 32 AVFs were successfully thrombolysed by DPT, with technical success of 84.2%. Remaining six patients required angioplasty because of chronic nature of clot. In 82 patients who had venous stenosis, 80 cases were treated successfully by DPT followed by angioplasty with technical success of 97.5%. In third group ( n = 28), who developed thrombosis post angioplasty, 100% success rate was noted. The mean length of thrombus was 31.4 ± 4.6 mm and mean diameter of thrombosed vein was 10.5 ± 1.2 mm. There were no major complications encountered during the procedure. Minor complications were seen in 19 patients which included prolonged oozing from puncture site and local hematoma formation.

Conclusion:

Ultrasound guided DPT with urokinase is a safe and economical option for salvaging thrombosed AVF without vascular stenosis that does not need angioplasty.
Domination through precarization: From Butler’s humanitarian ethics to Marx’s political economy
Authors: Frumer Naveh
Published: February 2023

The key critical idea of Judith Butler’s recent work is ‘differential precarity’: how the same network of social dependency that sustains our existence creates a divide between those for whom it proves protective and enabling and those for whom it implies precarious social existence. Yet the examples Butler analyses present problems not only with how precarization is unequally manifested but how it is rooted in the structures of dependency. Against her intent, Butler reduces systemic problems of dependency to distributive inequalities of precarity. We propose to adapt and enrich Butler’s insight by integrating it into a Marxist framework. The result is a problematization of how capitalist societies are predicated on a productive feedback loop between dependization and precarization. We argue the critical grammar of dependency–precarity helps articulate the latent normative content of Marxism, while the latter advances this grammar beyond the limited envelope of distributivism, offering a critique focused on the nature of dependency and not only its ensuing precarity.
Revision of Failed Radial Head Arthroplasty
Authors: Heifner John J. , Kolovich Gregory P. , Bolano Luis E. , Sibley Paul A. , Gonzalez Gilberto A. , Mercer Deana M.
Published: February 2023

Background:

Revision of radial head arthroplasty (RHA) may be indicated in cases of prosthesis loosening and malposition. Inherent difficulties in revision surgery include poor bone stock and disrupted soft tissue envelope. Although cases of RHA used for revision of failed RHA are rare, there is reasonable expectation for increasing frequency of these cases due to the increasing incidence of primary RHA. Furthermore, there is an increasing demand for postoperative recovery of function; thus, surgeons may consider revising a failed RHA to a new RHA. We report on series of failed RHA which were revised to a new radial head prosthesis.

Methods:

A retrospective review was performed at multiple institutions for a single radial head prosthesis used for revision of a failed radial head prosthesis. Clinical and radiographic outcomes were collected with a minimum of 1 year of follow-up.

Results:

Across 11 patients at a mean follow-up of 45.1 months, the mean Mayo Elbow Performance Score was 81.7; mean Disabilities of the Arm, Shoulder, and Hand scores were 24.4; and mean Visual Analog Scale for pain was 0.6. Radiographic analysis yielded no evidence of capitellar wear or stem loosening.

Conclusion:

A radial head prosthesis can produce satisfactory results when used for revision of a failed prosthesis. Inherent difficulties in revision surgery include the potential for reduced bone stock and a disrupted soft tissue envelope. Elements of prosthesis design which may contribute to effectively managing revision surgery include a long stem with in-growth surface and prosthetic head alignment to the axis of forearm rotation.

Published: February 2023

Background and aims

Endovascular treatment for cerebrovascular disease is accepted as a first-line option with level I evidence in patients with an early and late time of window of onset symptoms, and an additional option in patients who do not respond or with contraindications to systemic thrombolysis; nevertheless the efficacy and outcomes of some groups were not clear, one of them are patients aged 80 years and older, because they were excluded of the trials, so the evidence is controversial with significant heterogeneity, for that reason in our study, we decided to analyze the age in the patients treated in our stroke center, as a predictor of prognosis, and to provide a baseline for the establishment of personalized treatment plans.

Methods

Observational, retrospective study of patients that received endovascular treatment for cerebrovascular disease in a Colombian stroke center between 2016 and 2020, continuous and categorical variables were compared using the Student's t test and Chi-Square. To determine cut-off points in the variable against death and Rankin score variable on 90th day.

Results

In total, 108 patients were recruited, 35 of them were of 80 or more years, and the mean age was 72.7 years, we found age as a significant variable to predict the risk in the population over 80 years of age [RR 3.37 CI (95% 1.14–103) p  =  0.029].

Conclusions

Age younger than 80 is a significant predictor for results and long-term outcomes in patients suffering from stroke, and in patients older than 80 years old a Thrombolysis in Cerebral Infarction score 2b-3 is a predictor of good outcomes. Further studies are needed to evaluate the relationship between intrahospital complications and long-term outcomes.
Safety and feasibility of the Wahoo Hybrid Access System, a dual-mode guide catheter, in a range of neuroendovascular procedures
Authors: Waters Michael J , Vargas Jan , Turk Aquilla , Chaudry Imran , Turner Raymond D
Published: February 2023

Background

There is a clinical need for a guide catheter with combined stability and navigability, which can be used in a biaxial system for neuroendovascular procedures in place of triaxial systems.

Objective

To assess the safety and feasibility of the Q’Apel Medical Wahoo Hybrid Access System, a dual-mode 0.072″ internal diameter guide catheter, in a range of neuroendovascular procedures.

Methods

We performed a retrospective analysis of consecutive cases from a high-volume tertiary center in which the Wahoo Hybrid Access System was used as the guide catheter. Characteristics of the patients, vascular lesions, procedure, and procedural complications were assessed.

Results

A total of 102 patients were included for analysis. Vascular lesions were in the anterior circulation in 90 of 102 (88%), and posterior circulation in 12 of 102 (12%). Eighty-four cases were ruptured or unruptured aneurysm embolization procedures, the majority being balloon-assisted coiling (42%) and flow diversion (42%). All cases, including flow diversion, were performed as a biaxial system. There were no instances of prolapse of the catheter beyond the arterial segment in which it was initially placed. The procedure was able to be performed to completion in 101 of 102 (99%) cases. Thromboembolic complications occurred in 5 of 102 (5%); causality in two cases was unrelated to the guide catheter, and three were indeterminate.

Conclusions

The Wahoo guide catheter is safe and feasible when used in a variety of neuroendovascular procedures. It can accommodate a range of devices, can be safely navigated into distal vasculature, and provides support for a range of procedures, including those which traditionally require triaxial support.
Fischer indole synthesis in DMSO/AcOH/H2O under continuous flow conditions
Authors: Wang Mei , Yan Shenghu , Zhang Yue , Gu Shunlin
Published: February 2023

A new continuous flow synthetic method for preparing indole and its derivatives are successfully developed to overcome the disadvantages of traditional batch methods, such as low conversion rates, long reaction times, and amplification effects. The method represents a sustainable and efficient preparation of indole and its derivatives without the need for additional catalysts. By investigating the effects of the reaction temperature, the solvent, the equivalence ratio, and the residence time, high conversion rates and excellent yields were simultaneously achieved within 20 min under optimized conditions. For the template reaction, DMSO/H2O/AcOH = 2:1:1 is used as the solvent, the reaction temperature is 110 °C, and the ratio of phenylhydrazine hydrochloride to cyclopentanone is 1:1.05. Indole and a wide array of its derivatives are synthesized to verify the universality of the method, and most of the reactions exhibit satisfactory conversion rates and high yields are obtained. This new continuous flow method is more suitable for industrial scale-up relative to traditional batch methods.

Spectral fabulations: Belgrade drag performances refashioning socialist memories
Authors: Pope Jill
Published: February 2023

This article explores how drag performers in late postsocialist Belgrade refashion memories of socialist Yugoslavia, queering memory by disrupting the linear temporality of the postsocialist transition and challenging the erasure of the city’s socialist Yugoslav past. Belgrade is home to a thriving drag community, including a growing group of performers who engage with memories of socialist Yugoslavia, drawing on its diverse legacy from costumes, ideologies and cultural production. Analysing performance material from two of these drag identities – Gospođa Pereca and Novoslovenka – I argue that drag performers could be considered spectral fabulations, which emerge in the haunted landscape of postsocialist Belgrade, a city characterised by political depression, particularly for its LGBTQ+ community. Confronting literature on hauntings and queer performance, spectral fabulation sees drag identities in Belgrade as posthuman apparitions who use socialist memory to disrupt teleological understandings of history as well as to imagine utopian futures, which actively work against the conditions of political depression in the city. This ultimately points to the indeterminacy of the postsocialist transition, containing the potential form for both political depression and queer futurities.
Collective memory and trans history in the Italian context: Archival practices and the creation of the first trans archive in Italy
Authors: Voli Stefania , Virtù Ludovico
Published: February 2023

In recent years, there has been a growing scholarly interest in the relationship between history, memory, archiving and trans experiences. This body of work has shown how questioning the praxis of archiving from the vantage point of trans experiences has the potential to problematise cis-heteronormative assumptions around the body, time and space and to queer the epistemological premises around what constitutes archives and archival practices. In this article, we present the experience of the project ArchiviST* – Archivi Storia Trans (Trans History Archives) which aims to create the first archive exclusively dedicated to the history of trans lives and activism in contemporary Italy. The project has been promoted by Trans Identity Movement, the most influential and long-lived trans association in Italy. Since its birth in 1979, Trans Identity Movement informally collected a substantial documentary heritage concerning trans and LGBTQIA+ history as a political practice to preserve the counter-memories of its people and movements. The ArchiviST* project carries out the inventorying and digitising of the materials, together with the collection of original video-recorded interviews with pioneering activists of the trans movement. By presenting a reflection on the process of ‘reconstructing’ an archive in this context, we unpack and explore some of the key issues surrounding trans archiving and collective memories in the Italian context: what counts as collective memory? What types of relationships are established between trans memories and the documents present in the archive? What memories have (not) been told, and what voices and subjects have (not) emerged as protagonists? We encourage a reflexive attitude towards the practice of trans archiving to problematise established historiographical categories, such as time, private/public, political engagement, life history and memory and to recognise the ethical and methodological challenges that such a path poses to historiography and archive research in general.
An Archive of Feelings @ 20: An interview with Ann Cvetkovich
Authors: Cvetkovich Ann , Dragojlovic Ana , Quinan CL
Published: February 2023

Feminist and queer studies scholar Ann Cvetkovich’s trailblazing book An Archive of Feelings: Trauma, Sexuality, and Lesbian Public Cultures has had an immense influence on the field of memory studies, inspiring new bodies of scholarship on queerness, trauma, and memory. In this interview, Cvetkovich discusses the impact that some of the book’s central concepts have had on the field of memory studies over the last 20 years. Cvetkovich also reflects on the role that An Archive of Feelings has had in bringing affect into feminist and queer work on sexuality, intimacy, and everyday life. Furthermore, she reflects on another of her groundbreaking books, Depression: A Public Feeling, in which she applies queer cultural analysis to unusual archives and writes critical memoir in order to situate depression as an historical category. The interview closes with Cvetkovich’s reflections on her current work on queer Indigenous approaches to trauma.

Delayed Presentation of Actinomycosis Following Orthognathic Surgery: An Old Nemesis and a Difficult Diagnosis: Case Presentation and Review of the Literature
Authors: Krisko Alexander J. , Van Sickels Joseph E.
Published: February 2023

Study Design

Review of the literature with report of Case.

Objective

To review the presentation of Actinomycosis specifically as it occurs with mandibular osteotomies.

Methods

A review of the literature and report of an additional case.

Results

While minor infections secondary to local factors are usually seen 2–3 weeks after surgery, late infections are rare. Host factors may play a role. When actinomycosis is diagnosed, long-term antibiotics are necessary.

Conclusions

Actinomycosis is very rare following orthognathic surgery. It usually occurs in the mandible and following a sagittal split. Time of presentation for actinomycosis can vary from 6 weeks to 4 months as in our case. Infections occurring this late after surgery should be treated with suspicion of actinomycosis obtaining both cultures and tissue biopsies. Treatment involves an incision and drainage and long-term antibiotics.
A systematic review of the tensions between the public and private in adolescents’ social networks: New education challenges
Authors: González-Villa Ángela , Gewerc Adriana
Published: February 2023

Social networks are colonised by a culture of confession that turns teenager privacy into a commodity to achieve recognition and social acceptance. This display accelerates the porosity of the boundaries between the public and the private and feeds surveillance capitalism. The aim of this systematic review is to examine the empirical evidence on the public-private interaction of teenagers’ contributions to social networks in the last 5 years in databases: Eric, Scopus and Web of Science. Based on the Prisma Statement, the initial search produced 1449 documents, of which 81 were included in the final analysis after the application of exclusion and inclusion criteria and the purging of duplicates. The results show a field of study developed with a decreasing trend in production in recent years, knowledge gaps and discordant findings. It is concluded the need to build solid knowledge and initiate new lines in the study of the issue in order to understand the exhibition of teenagers in social networks. It is points out the urgency of a training based on their own media practices and in digital literacy for a broad understanding of online privacy.

Objective

The aim of this study was to assess the feasibility and potential effectiveness of an 8-week virtual EMG biofeedback intervention for patients with CLBP.

Methods

Patients with CLBP completed validated baseline and post-intervention assessments of pain intensity and interference (Brief Pain Inventory), back pain-related disability (Oswestry Disability Index), anxiety and depression (Hospital Anxiety and Depression Scale). Participants underwent a series of Quantitative Sensory Testing (QST) procedures assessing responses to mechanical stimuli during two separate visits (baseline and post-intervention). In addition, we assessed, using surface EMG, the muscle tension in the trapezius, latissimus, and low back muscles at each session. Patients were randomized into the EMG biofeedback intervention or usual care group. Factorial analysis of variance including the interaction between treatment group and time was used to analyze the changes in pain intensity (primary outcome), pain interference, disability (secondary outcomes), anxiety, and depression (secondary outcomes).

Results

Compared to the treatment as usual comparison group, patients in the EMG biofeedback group reported lower pain intensity after completing the intervention (mean group difference 0.9, 95% CI −1.07, −0.32; p≤0.01). Compared to baseline, participants in the EMG biofeedback group demonstrated statistically significant reductions in pain interference (mean difference 1.3, 95% CI 0.42, 2.1; p≤0.01), disability (mean difference 4.32, 95% CI 1.2, 7.3; p≤0.01), and significant increases in low back pain thresholds (mean difference 0.5, 95% CI −0.87, −0.05; p≤0.01), assessed by QST. However, no significant group by time effects were observed for secondary outcomes: pain interference, disability, and low back pain thresholds. In addition, significant changes were observed in muscle tension for the trapezius, latissimus, and low back muscles in the EMG biofeedback group ( p<0.001).

Conclusions

Virtual EMG biofeedback shows promise as a potential therapy for reducing pain and disability in individuals with chronic nonspecific low back pain.
Planning and designing universal access to social services. A pioneering local program on welfare spaces in Italy
Authors: Bricocoli Massimo , Marani Benedetta , Sabatinelli Stefania
Published: February 2023

The combined effect of socio-economic and demographic changes exerts pressure on the welfare systems and makes it more urgent to provide appropriate answers to increasing and diversifying needs with scanter resources. Local social services are strongly committed to such challenges. The physical features of the spaces of welfare, often neglected both by research and by implementation, play a fundamental role in the attempt to innovate and extend access to social assistance services. The article analyses how, at the urban level, the interplay between urban planning and welfare policies might contribute to reshaping the traditional physical structures of social welfare services and, through these, the patterns of access to local welfare. Building on an experimental project tested and then consolidated in Milan, the article analyses the role of the spatial dimensions of welfare places, namely the contexts, settings and artefacts, in increasing accessibility, lowering the threshold, reducing stigmatization, ensuring (or not) the coherence between policies and programmes’ objectives and approaches and the features of the spaces where such programmes and policies are implemented and where citizens experience them. Moreover, it discusses alternative planning strategies and tools in use to design the current spaces for welfare and to govern their distribution and organisation at the city level.
Preparing Early Childhood Educators/Interventionists: Scoping Review Insights Into the Characteristics of Rural Practice
Authors: Vilches Silvia L. , Pighini Maria J. , Stewart Mary J. , Rossa-Roccor Verena , McDaniel Beth
Published: February 2023

Rural regions struggle to retain early intervention (EI), special education (SE), and early childhood education (ECE) supports for children with developmental delay and/or disability, yet there is little guidance to prepare pre-service students for rural practice. This exploratory scoping review of rural EI/SE/ECE practice in the United States and Canada, where EI for children birth to 8 years is part of the education and development continuum (as opposed to health), found four characteristics: a broader scope of practice, the importance of being a whole person, doing more outreach to engage families, and negotiating personal/professional boundaries. Retention is enhanced when educators feel effective and appreciated. Regionalized (not national) funding sources may be limiting disciplinary advances, and cultural/racial inclusivity, equity issues, travel, and distance barriers were under-studied. Cross-national variation in EI/SE/ECE terms impeded the search. Future research should highlight the unique multidisciplinary and multijurisdictional nature of rural EI/SE/ECE practice across the developmental span.
