A retrospective review of single-position prone lateral lumbar interbody fusion cases: early learning curve and perioperative outcomes
Authors: Patel Ashish , Rogers Michael , Michna Rebecca 
Published: April 2023

Abstract
Purpose
The objective of this study was to discuss our experience performing LLIF in the prone position and report our complications.

Methods
A retrospective chart review was conducted that included all patients who underwent single- or multi-level single-position pLLIF alone or as part of a concomitant procedure by the same surgeon from May 2019 to November 2022.

Results
A total of 155 patients and 250 levels were included in this study. Surgery was most commonly performed at the L4–L5 level (n = 100, 40%). The most common preoperative diagnosis was spondylolisthesis (n = 74, 47.7%). In the first 30 cases, 3 surgeries were aborted to an MIS TLIF. Complications included 3 unintentional ALL ruptures (n = 3/250, 1.2%), and 1 malpositioned implant impinging on the contralateral foramen requiring revision (n = 1/250, 0.4%), which all occurred within the first 30 cases. Out of 147 patients with more than 6-week follow-ups, there were 3 cases of femoral nerve palsy (n = 3/147, 2.0%). Two cases of femoral nerve palsy improved to preoperative strength by the 6th week postoperatively, while one improved to 4/5 preoperative strength by 1 year. There were no cases of bowel perforation or vascular injury.

Conclusion
Our single-surgeon experience demonstrates the initial learning curve when adopting pLLIF. Thereafter, we experienced reproducibility in our technique and large improvements in our operative times, and complication profile. We experienced no technical complications after the 30th case. Further studies will include long-term clinical and radiographic outcomes to understand the complete utility of this approach.
Barriers and facilitators to physical activity promotion in eyecare: a qualitative study of eyecare professionals’ perceptions
Authors: Lindsay Rosie K. , Smith Lee , Allen Peter M. 
Published: April 2023

Abstract
Aim
The aim of this study is to explore the barriers and facilitators to implementing physical activity promotion into eyecare services, from the perspective of eyecare professionals.

Subject and methods
Eleven eyecare professionals were recruited for qualitative interviews. Thematic analysis was used to identify key themes within the interview data.

Results
Five themes which represented barriers to physical activity promotion were identified in the interviews: lack of time available to discuss physical activity, health and safety concerns, fear of creating a negative experience for the patient, lack of knowledge, and resistance from patients. Facilitators to physical activity promotion identified in the interviews were categorised into two themes: easy access to information about physical activity, and organisational change.

Conclusion
To enable physical activity promotion in eyecare, individual and organisational change is required. Organisational change includes providing time and resources to enable physical activity promotion in eyecare. Individual change can be facilitated by providing training, which enables eyecare professionals to be confident providing physical activity advice.

Sexual Boundary Violations: Exploring How the Interplay Between Violations, Retributive, and Restorative Responses Affects Teams
Authors: van Baarle Eva , van Baarle Steven , Widdershoven Guy , Bal Roland , Weenink Jan-Willem 
Published: April 2023

AbstractStudying and discussing boundary violations between people is important for potentially averting future harm. Organizations typically respond to boundary violations in retributive ways, by punishing the perpetrator. Interestingly, prior research has largely ignored the impact of sexual boundary violations and retributive dynamics on teams. This is problematic as teams provide an obvious setting not only to detect and discuss troubling behavior by peers, but also for learning how to prevent future harm. Therefore, in this study we explore team-level experiences regarding sexual boundary violations and organizational responses to these incidents. Drawing on an in-depth case study, our findings shed light on the profound negative consequences of a retributive organizational response to sexual boundary violations. Additionally, our findings show how a restorative approach, inviting teams to reflect on the violations and their impact, can help teams to recover. Our main contribution involves a model that demonstrates how the interplay between sexual boundary violations, retributive, and restorative organizational responses affects teams. This model shows how combining these responses can acknowledge distress within teams, heal relationships between team members through dialogue, and open up the possibility to learn from these events. This model extends prior research focusing on individual actions and outcomes regarding violations. Additionally, by combining retributive and restorative organizational responses in one model, we extend the literature on restorative organizational responses to boundary violations.
Does academic freedom matter for global student mobility? Results from longitudinal network data 2009–2017
Authors: Vögtle Eva Maria , Windzio Michael 
Published: April 2023

AbstractAcademic freedom and global student mobility are both topics high on the scientific and political agenda. However, the relationship between transnational student mobility and academic freedom in national higher education systems has not yet been investigated cross-nationally. This study intends to answer the question on how a countries’ level of academic freedom impacts on its’ attractiveness as a study destination. We analyse this connection from a network analytic perspective. While our data covers 167 countries as receivers and senders, our network analysis takes the attributes of countries and their relationship to each other into account in order to estimate the net effect of academic freedom ties in the network of global student mobility. We expect global student mobility to be directed from countries with low levels of academic freedom to countries with high levels of academic freedom. At the same time, academic freedom might be an attractive characteristic of a country to retain students in its domestic higher education system.
Lessons from the Women and Gender Constituency: Interrogating Civil Society Strategies for Organising in the UNFCCC
Authors: Flavell Joanna 
Published: April 2023

AbstractWhile scholarship on the topic of gender and the environment is steadily growing, little is known about the challenges faced and successes seen by women and gender NGOs operating as a central part of environment-focused civil society. In this paper, I offer such an analysis, examining the political strategies—rhetorical and procedural—mobilised by the Women and Gender Constituency (WGC) in the United Nations Framework Convention on Climate Change (UNFCCC). I argue that the WGC has seen lots of success in mobilising arguments that foreground women’s vulnerability to the effects of climate change. But at the same time, the constituency has seen far more resistance to more intersectional feminist arguments that interrogate the role of masculinised discursive power in shaping climate politics. This is at least in part a result of a wider structure of civil society that pigeonholes different identities (e.g. gender, youth, indigenous peoples) in a way that separates their deeply interconnected struggles. Understanding this structural barrier, or dark side of civil society, is crucial to envisioning a more fruitful integration of civil society in sustainability politics.
Using Life Course Theory to Explore the Association Between Autistic Traits, Child, Family, and School Factors and the Successful Transition to Secondary School
Authors: Whelan Moira , McGillivray Jane , Rinehart Nicole J. 
Published: April 2023

AbstractLife Course Theory contends that school transitions can interrupt academic and wellbeing trajectories, depending on child, family, and school factors. Hierarchical regression analyses examined how autistic traits were associated with school transition outcomes. Autistic traits explained 12% of the variance in Quality of Life (QOL), 24% of the variance in mental health and 9% of the variance in school belonging. When autistic traits were accounted for, gender was a significant predictor of changes in QOL whereas changes in school belonging were predicted by cognitive functioning, parent education, school attendance and school refusal. Changes in mental health after transition were mostly predicted by family factors including family structure, family functioning and parent education but were also significantly predicted by sleep problems.
Alexithymia and Alcohol Use: Evaluating the Role of Interoceptive Sensibility with the Revised Multidimensional Assessment of Interoceptive Awareness
Authors: Lyvers Michael , Thorberg Fred Arne 
Published: April 2023

AbstractAlexithymia has been linked to risky or problematic alcohol use, with a common interpretation invoking deficient emotion regulation and use of alcohol to cope with distress. An alternative explanation positing a general deficit of interoception in alexithymia suggested that poor awareness of internal cues of overconsumption may promote excessive drinking. The present study assessed predictions based on these hypotheses in 337 young adult alcohol users recruited online. Participants completed validated questionnaire indices of alcohol use, alexithymia, emotion regulation, interoceptive sensibility, and sensitivity to reward and punishment. Alcohol use was positively correlated with alexithymia and reward sensitivity, and negatively correlated with emotion regulation as expected, but was uncorrelated with interoceptive sensibility. Alexithymia was not significantly correlated with most dimensions of interoceptive sensibility but was highly negatively correlated with emotion regulation. Hierarchical regression controlling for demographic variables indicated that alexithymia, emotion regulation, sex, and sensitivity to reward and punishment were significant predictors of alcohol use levels. Bootstrapped mediation test controlling for all other variables indicated mediation of the association between alexithymia and alcohol use by deficient emotion regulation but not interoceptive sensibility. Results supported the emotion regulation deficit interpretation of the association of alexithymia with alcohol use. Limitations concerning interoception measurement, online samples, self-report measures, cross-sectional designs, and collection of data during the COVID-19 pandemic are discussed. Future research could follow up on these findings by testing interoceptive accuracy in addition to interoceptive sensibility in relation to alexithymia and alcohol use.
Experimental and analytical study of the influence of the incident heat flux in cables heat release
Authors: Lázaro David , Alonso Alain , Lázaro Mariano , Jiménez Miguel Ángel , Alvear Daniel 
Published: April 2023

AbstractCone calorimeter is widely used to study fire behaviour of materials employing small size samples. This equipment allows obtaining parameters such as time to ignition (TTI), heat of combustion, mass loss rate (MLR), or heat release rate (HRR) under different heat fluxes. Some studies have considered a linear fitting between MLR and HRR peaks and the incident heat flux. In accordance with this hypothesis, the computer model Fire Dynamics Simulator (FDS) has included a simple model to extrapolate burning rate data collected from a cone calorimeter test to the heat feedback occurring during a simulation. Nevertheless, deviation in the prediction of the HRR peaks at 75 kW m−2 of approximately 39.3% and of 37.1% for the first and second peak, respectively, were found. Therefore, this work presents a correlation between the incident heat flux and the global HRR per unit area curve, testing up to five different cables and several heat fluxes. To do so, some modifications of the FDS correlation are performed to consider the effect of the flame heat flux in the decomposition of the cables. Once experimental data are acquired, a computational analysis is carried out using FDS to achieve the flame heat flux in the samples. Additionally, this flame heat flux has also been obtained from the literature. As a conclusion, the addition of the flame heat flux to the cone calorimeter incident heat flux provides better predictions than the linear fitting methodology defined in the FDS Guide. Furthermore, this correction is checked with: (1) the example included in FDS guide, decreasing the HRR peaks errors from around 38% to around 25%; and (2) to seven different cables from the literature, decreasing the HRR peaks relative errors, as average, from 14.2 to 9.5% approximately.
Where did you come from and where are you heading to, thermal analysis of heating effects?
Authors: Šesták Jaroslav 
Published: April 2023

AbstractThe review summarizes the current state, outlook and development of the field of thermal analysis, emphasizing the study of thermal effects as the basis of all other methodologies. Heat and its understanding intertwines throughout the entire civilization from the Greek philosophers through the middle ages to today’s advanced technological era. The foundations of the field of thermal analysis, where heat acts as its own agent, date back to the nineteenth century, and the calorimetric evaluation of heat fluxes became the basis. It views the processes of calibration and rectification specifies the iso- and noniso- degrees of transformation, explains the role of the equilibrium background, which is especially necessary in kinetics. It introduces a new concept of thermodynamics with regard to the constancy of first derivatives and discusses the role of standard temperature and its non-equilibrium variant—tempericity. It describes the constrained states of glasses and assesses the role of dimensions in material science. Finally yet importantly, it deals with the influence of thermoanalytical journals, their role in presenting unusual results, and discusses the role of the dissident science. It also describes the level and influence of adequate books and finally describes discussions and perspectives, i.e. where to look better interpretation for and what is the influence of current over-sophisticated devices.
Localizing and prioritizing roof greening opportunities for urban heat island mitigation: insights from the city of Krefeld, Germany
Authors: Brenner Jana , Schmidt Stefan , Albert Christian 
Published: April 2023

Abstract
Context
Climate change may increase the frequency, intensity, and occurrence of urban heat islands (UHI) in cities worldwide, often with harmful impacts on citizens. Strategic planning and implementation of multifunctional green roofs promises to help mitigating UHI effects, but cities often lack up-to-date scientific understanding of best-suited locations.

Objectives
The aim of this paper is to develop and apply a socio-ecological approach to explore and prioritize present and prospective opportunity spaces for roof greening based on remote sensing data to mitigate UHI effects.

Methods
The city of Krefeld, Germany, serves as a case study. The research design consists of three steps, applied to the conditions of 2019 and a 2030 scenario: (i) Examining residents’ vulnerability to heat, (ii) Assessing existing green roofs and potentials for greening, and (iii) Prioritizing opportunity spaces for roof greening to reduce UHI effects.

Results
Findings showed that the area of high vulnerability due to combined high heat exposures and densities of sensitive residents in Krefeld accounts for almost 300 hectares in 2019 and may triple until 2030. More than 90% of evaluated horizontal roofs have no vegetation cover. Highest priority for roof greening is attributed to 59 ha and 113 ha of roofs in 2019 and 2030, respectively.

Conclusions
The findings can inform strategic roof greening efforts for climate adaptation, e.g. for the extension of cadasters, and facilitate communication to increase understandings, public and policy support, and implementation.

AbstractAccurate localization of the site(s) of active disease is key to informing decision-making in the management of refractory pituitary adenomas when autonomous hormone secretion and/or continued tumor growth challenge conventional therapeutic approaches. In this context, the use of non-standard MR sequences, alternative post-acquisition image processing, or molecular (functional) imaging may provide valuable additional information to inform patient management.

AbstractWe characterize the Hilbert–Schmidt class membership of commutator with the Hilbert transform in the two weight setting. The characterization depends upon the symbol of the commutator being in a new weighted Besov space. This follows from a Schatten class Sp result for dyadic paraproducts, where $1< p < \infty $

Published: April 2023

Abstract
This article studied the sorption behavior of Cs(I) ions from aqueous solutions onto molybdenum vanadate@bentonite (MoV@bentonite) composite. MoV@bentonite has been fabricated using the precipitation method and was characterized by different analytical tools including, FT-IR, XRD, and SEM attached with an EDX unit. The sorption studies applied on Cs(I) ions include the effect of contact time, pH, initial metal concentrations, ionic strength, desorption, and recycling. The experimental results revealed that in the adsorption process carried out after equilibrium time (300 min), saturation capacity has a value of 26.72 mg·g−1 and the sorption of Cs(I) ions is dependent on pH values and ionic strength. Sorption kinetic better fit with the pseudo-second-order model; sorption isotherms apply to Langmuir, Freundlich, and Dubinin-Radushkevich (D-R) isotherm models. Data of thermodynamic parameters indicate that sorption is spontaneous and endothermic. Recycling experiments show that MoV@bentonite could be used for 7 cycles and the best eluant for the recovery of Cs(I) ions is 0.1 M HCl (76.9%). All the obtained data clarify that MoV@bentonite is considered a promising sorbent for the sorption of Cs(I) ions from aqueous solutions.

AbstractLittle information is available on the magnetic resonance imaging (MRI) determination of the hippocampal formation (HF) during the perinatal period. However, this exploration is increasingly used, which requires defining visible HF landmarks on MRI images, validated through histological analysis. This study aims to provide a protocol to identify HF landmarks on MRI images, followed by histological validation through serial sections of the temporal lobe of the samples examined, to assess the longitudinal extent of the hippocampus during the perinatal period. We examined ex vivo MRI images from nine infant control brain samples. Histological validation of the hippocampal formation MRI images was obtained through serial sectioning and examination of Nissl-stained sections at 250 μm intervals along the entire length of the hippocampal formation. Up to six landmarks were identified both in MRI images and the serial histological sections. Proceeding in an anterior to posterior (rostrocaudal) direction, these were as follows: 1) the limen insulae (fronto-temporal junction); 2) the beginning of the amygdaloid complex; 3) the beginning of the lateral ventricle; 4) the caudal limit of the uncus, indicated by the start of the lateral geniculate nucleus (at the level of the gyrus intralimbicus); 5) the end of the lateral geniculate nucleus (beginning of the pulvinar); and 6) the beginning of the fornix. After histological validation of each of these landmarks, the full longitudinal length of the hippocampal formation and distances between landmarks were calculated. No statistically significant differences were found in total length or between landmarks. While the HF is anatomically organized at birth, its annotation is particularly challenging to perform. The histological validation of HF landmarks allows a better understanding of MRI images. The proposed protocol could be useful to assess MRI hippocampal quantification in children and possible variations due to different neurological diseases.
