Tumbling Backward: Scrolling, Temporality, and One Direction Fan Narratives on Tumblr
Authors: Mecklenburg Anne-Charlotte 
Published: May 2022

Abstract
The English/Irish boy band One Direction (2010–16) was one of the first major artists to capitalize on social media's potential for building and maintaining a dedicated fan base over time. The One Direction fandom was particularly pervasive on the blogging site Tumblr, which was prominent between 2007 and 2018 both for its chaotic and confusing “rhizomatic” structure, as well as its popularity with marginalized users and fan communities. This article uses the One Direction fandom as a lens through which to examine the affordances of Tumblr as a platform. It argues that Tumblr encourages its users to draw on the fragmentary, potentially incoherent pieces of information they regularly encounter on the site in order to collectively create narratives that can accommodate them. In other words, Tumblr's platform characteristics produce a queer temporality that combines provisionality and multiplicity with narrative forms and meanings. The article highlights three specific characteristics of Tumblr's platform—its “backward scroll,” its tagging structure, and its recirculation of content—that together encourage users to understand time as comprised of these multiple provisional pasts, presents, and futures. The article points toward the way that narrative and theories of collective storytelling can be used as frameworks for understanding social media platforms.

BACKGROUND:
Chronic subdural hematomas (CSDHs) are common in the elderly population and patients taking antiplatelet/anticoagulation medications. Middle meningeal artery (MMA) embolization has become an adjunctive treatment to observation and surgery. Despite many embolization techniques, best practices for optimal CSDH resolution remain unknown.

OBJECTIVE:
To report a retrospective case series of MMA embolization for CSDHs regarding rate of hematoma improvement and the significance of distal embolic penetration into the falx.

METHODS:
Retrospective chart review was performed on all patients who underwent MMA embolization for CSDHs between January 2017 and June 2021. Patient demographics, clinical presentation, anticoagulant use, and radiographic features were collected. Pre-embolization and postembolization computed tomography scans were analyzed for volumetric changes and assessed for midline penetration of embolic material in the falx.

RESULTS:
MMA embolization was performed in 37 patients and 53 hemispheres. Older patients took longer to obtain complete resolution of CSDHs (r = 0.47, P = .03). Patients with larger pre-embolization (r = 0.57, P = .007) and postembolization (r = 0.56, P = .008) CSDH volumes took longer to completely resolve. Patients who had n-butyl cyanoacrylate embolization with midline penetration, as evidenced by the “bright falx” sign, had faster improvement rates than those who did not (5.64 cm3/d vs 1.2 cm3/d, P = .02).

CONCLUSION:
Distal penetration of embolic material, particularly n-butyl cyanoacrylate, into the falx may lead to more rapid improvement of CSDH.
Thermogenesis is supported by high rates of circulatory fatty acid and triglyceride delivery in highland deer mice
Authors: Lyons Sulayman A. , McClelland Grant B. 
Published: May 2022

ABSTRACT
Highland native deer mice (Peromyscus maniculatus) have greater rates of lipid oxidation during maximal cold challenge in hypoxia (hypoxic cold-induced V̇O2,max) compared with their lowland conspecifics. Lipid oxidation is also increased in deer mice acclimated to simulated high altitude (cold hypoxia), regardless of altitude ancestry. The underlying lipid metabolic pathway traits responsible for sustaining maximal thermogenic demand in deer mice is currently unknown. The objective of this study was to characterize key steps in the lipid oxidation pathway in highland and lowland deer mice acclimated to control (23°C, 21 kPa O2) or cold hypoxic (5°C, 12 kPa O2) conditions. We hypothesized that capacities for lipid delivery and tissue uptake will be greater in highlanders and further increase with cold hypoxia acclimation. With the transition from rest to hypoxic cold-induced V̇O2,max, both highland and lowland deer mice showed increased plasma glycerol concentrations and fatty acid availability. Interestingly, acclimation to cold hypoxia led to increased plasma triglyceride concentrations at cold-induced V̇O2,max, but only in highlanders. Highlanders also had significantly greater delivery rates of circulatory free fatty acids and triglycerides due to higher plasma flow rates at cold-induced V̇O2,max. We found no population or acclimation differences in fatty acid translocase (FAT/CD36) abundance in the gastrocnemius or brown adipose tissue, suggesting that fatty acid uptake across membranes is not limiting during thermogenesis. Our data indicate that circulatory lipid delivery plays a major role in supporting the high thermogenic rates observed in highland versus lowland deer mice.
Fast Solvothermal Synthesis of Organic-Modified Single-Nanosized Zirconia Dispersed in Benzyl Alcohol

Published: May 2022

Abstract
To develop a fast synthesis method for organic-modified single-nanosized zirconium oxide (zirconia) particles dispersed in a solvent, the effects of temperature (300–400 °C), simultaneous modification with carboxylic acids, and precursors on the solvothermal synthesis with benzyl alcohol as a solvent were investigated. The formation of zirconia nanoparticles in this study occurred much faster than in a typical solvothermal condition (250 °C), and nanoparticles (2.6–3.4 nm) were successfully obtained at 2–5 min. The combination of TG and FT-IR analysis for the sample treated with benzoic acid at 400 °C confirmed that benzoic acid was chemically modified on the nanoparticles. In addition, the carbon number of the alkyl group of the zirconia precursor is an important factor that determines the size of zirconia.
Netflix: análisis comparativo del consumo de los usuarios antes y durante la pandemia
Authors: Iglesias Albores Emiliano Lucas 
Published: May 2022

Las plataformas digitales de distribución de contenido audiovisual se han convertido en un fenómeno de consumo que ha trastocado no solo la industria de producción, sino la forma de consumir y decidir lo que el usuario finalmente visualiza en la pantalla. Este trabajo plantea un acercamiento teórico y empírico a la forma en la que Netflix utiliza la información del usuario con la intención de predecir su consumo futuro. El artículo revisita los conceptos de algoritmo, base de datos e inteligencia artificial y, posteriormente, describe los resultados de un estudio de monitorización del consumo de Netflix. Es un estudio de caso en el que participaron doce usuarios de diferentes países y condición sociodemográfica que cumplimentaron plantillas de recolección de datos de su consumo cada dos semanas, durante seis meses, en distintas condiciones experimentales de oferta y de restricciones de la movilidad por la covid-19. El trabajo demuestra que cuanto mayor es el consumo en tiempo y en producciones de la plataforma, mayor es el poder de Netflix para generar sugerencias de consumo más certeras y aceptadas por los usuarios. El poder de predicción de consumos futuros de la plataforma, alimentado por el efecto pandemia, determina un escenario de control sobre la toma de decisiones humanas que se extiende, en otras plataformas de Internet, a todos los rincones y experiencias de la vida.

Published: May 2022

Salivary gland pathologies can be caused by obstruction, inflammation, bacterial or viral infections and neoplasia. Patients can present with acute or chronic presentations of salivary gland disease. Salivary gland disorders can have a significant impact on a patient's systemic health, oral health and quality of life. This article aims to increase awareness of salivary gland pathologies and how they may present in practice. It aims to offer general dental practitioners an understanding of how salivary gland disease can be managed in primary care and which conditions may warrant referral to secondary care, including suspected malignancy. The dental profession has a duty of care to recognize pathologies and treat or refer patients. This article provides an overview of non-neoplastic salivary gland disease, including diagnoses, management and when to refer to secondary care.CPD/Clinical Relevance: It is important to understand the signs, symptoms and management of non-neoplastic salivary gland diseases, and when to refer patients to secondary care.
SARS-CoV-2 omicron variant and the future of the pandemic
Authors: Samaranayake Lakshman 
Published: May 2022

Global infections with the Omicron variant of SARS-CoV-2 have now superseded all other similar variant infections we have witnessed thus far. The current global wave mainly caused by a descendant of the SARS-CoV-2 Omicron variant, called BA.2, is the most prevalent in UK, and has a natural history somewhat different from its predecessors. It also appears, that the so-called COVID-19 variant infections, in varying guises, are the harbingers of the post-COVID-19, ‘new normal’ world of the future, we have to live in. Here, we look at key features of SARS-CoV-2 variants, particularly BA.1 and BA.2, and the reasons for their phenomenal spread, vaccine efficacy against them, as well as the unfolding short-term outlook for the pandemic. CPD/Clinical Relevance: To describe the reasons for the high global prevalence of SARS-CoV-2 Omicron variant, particularly its BA.2 subvariant, and discuss the attendant implications for the dental profession.
What is the value of supplementary prescribing in the 2020s? A dietitian's perspective
Authors: Ruddock Nicola , Rees Sharon 
Published: May 2022

Background Non-medical prescribing is well-established in healthcare. Two models are used in practice: supplementary prescribing and independent prescribing. Supplementary prescribing incorporates higher levels of supervision and governance and is the model permitted for use by dietitians. Aim To explore the value of supplementary prescribing from a dietitian's perspective. Method Non-medical prescribing models will be evaluated to establish the benefits and drawbacks of each and discussed in relation to dietetic practice. Results Both models of prescribing are perceived positively by patients. Training for both models is identical and enables the practitioner to work within their scope of practice. However, the clinical management plan, necessary for supplementary prescribing, is limiting and can prevent practitioners from implementing their role efficiently. Conclusions Supplementary prescribing has allowed dietitians to begin prescribing, but for other professions, this model has been superseded by independent prescribing. Supplementary prescribing may be becoming redundant in the 2020s.
Teachers’ Reflection of Students’ Engagement in Online Language Learning: Multi-case Study
Authors: Al-Shlowiy Ahmed 
Published: May 2022

<p style="text-align:justify">Learning engagement is one of the most important issues facing online learning, which has many distractions beyond the teacher’s control and management. This study examined teachers’ observations of their students’ engagement in online learning and their efforts to engage them. Teachers can evaluate different factors and conditions that affect students’ perceptions, engagement, motivation, and achievement. Language learning is influenced by several factors, such as teachers’ rapport and interaction with their students, students’ interaction and collaboration, and their engagement with social activities in learning situations. This qualitative multi-case study collected data from five language teachers by semi-structured interviews, teachers’ self-reports, and observational notes about their experiences of students’ engagement in their online lessons. It lasted for 15 teaching weeks in a Saudi intermediate school during the second semester of 2020-2021. The thematic analysis results in four main categories; (a) teachers’ challenges, (b) students’ responsibilities, (c) environment and system, and (d) attitude and excuses. These categories are built on 11 themes that provide insights into the factors, challenges, and threats, which influence learning engagement in online courses for teachers and students. The study recommends some techniques to maintain the learning engagement and provides some suggestions for future research. </p>
Estimating the causal effect of treatment with direct-acting antivirals on kidney function among individuals with hepatitis C virus infection
Authors: O’Donnell Adrienne , Pham Nathan , Battisti Leandra , Epstein Rachel , Nunes David , Sawinski Deirdre , Lodi Sara 
Published: May 2022

Background
Direct-acting antivirals (DAA) are highly effective at treating Hepatitis C virus (HCV) infection, with a cure rate >95%. However, the effect of DAAs on kidney function remains debated.

Methods
We analyzed electronic health record data for DAA-naive patients with chronic HCV infection engaged in HCV care at Boston Medical Center between 2014 and 2018. We compared the following hypothetical interventions using causal inference methods: 1) initiation of DAA and 2) no DAA initiation. For patients with normal kidney function at baseline (eGFR>90 ml/min/1.73m2), we estimated and compared the risk for reaching Stage 3 chronic kidney disease (CKD) (eGFR≤60 ml/min/1.73m2) under each intervention. For patients with baseline CKD Stages 2–4 (15<eGFR≤90 ml/min/1.73m2), we estimated and compared the mean change in eGFR at 2 years after baseline under each intervention. We used the parametric g-formula to adjust our estimates for baseline and time-varying confounders.

Results
First, among 1390 patients with normal kidney function at baseline the estimated 2-year risk difference (95% CI) of reaching Stage 3 CKD for DAA initiation versus no DAA was -1% (-3, 2). Second, among 733 patients with CKD Stage 2–4 at baseline the estimated 2-year mean difference in change in eGFR for DAA initiation versus no DAA therapy was -3 ml/min/1.73m2 (-8, 2).

Conclusions
We found no effect of DAA initiation on kidney function, independent of baseline renal status. This suggests that DAAs may not be nephrotoxic; furthermore, in the short-term, HCV clearance may not improve CKD.
PENGELOMPOKAN TWEETS PADA AKUN TWITTER TOKOPEDIA MENGGUNAKAN ALGORITMA DENSITY BASED SPATIAL CLUSTERING OF APPLICATIONS WITH NOISE

Published: May 2022

Social media has become a trend for Indonesian people to express opinions, socialize, and exchange ideas. Internet users in Indonesia in 2021 will reach 202.6 million, 84% of whom use the internet to access social media. Twitter is one of the popular social media in Indonesia. This phenomenon is an opportunity for companies to use Twitter as a marketing tool, one of which is a marketplace company in Indonesia, Tokopedia. This research is intended to cluster tweets uploaded by the @tokopedia Twitter account to find out the type of content that gets a lot of likes and retweets by followers of the @tokopedia Twitter account. Cluster formation is done by applying the Density-Based Spatial Clustering of Applications with Noise algorithm (DBSCAN). DBSCAN is a clustering algorithm based on density. The DBSCAN algorithm requires two parameters, namely the radius (Eps) and the minimum number of objects to form a cluster (MinObj). This research conducted several experiments with different Eps and MinObj parameters on 1.344 tweets that had gone through the stages of removing duplication, text preprocessing, and feature selection. The quality of the cluster formed is measured using the Silhouette Coefficient. Based on the highest average Silhouette Coefficient, the parameter values of Eps=5 and MinObj=3 with Silhouette Coefficient = 0.575 are determined as the best parameters that produce 2 clusters and 7 noise. The type of content that has the highest average number of likes and retweets is the WIB (Indonesian Shopping Time) campaign, so Tokopedia can use this type of content as a marketing tool on Twitter social media because this type of content is preferred by followers of the @tokopedia Twitter account. Keywords: Twitter, Tokopedia, Clustering, DBSCAN, Silhouette Coefficient
Efficient Breach and Ex-post Disgorgement of the Defendant’s Gain: A Comparative Contract Law and Economics Perspective
Authors: Dnes Antony W. , Garoupa Nuno 
Published: May 2022

Abstract
Compensating the plaintiff’s expectancy loss is the established remedy for breach of contract in common-law jurisdictions. Legal theory has examined losses and gains extending beyond lost expectancy, especially gain-based disgorgement as a remedy reflecting the restitution interest in contract law. The theory of efficient breach implies that restitution remedies inaccurately compensate loss, whereas the case in jurisprudence for gain-based disgorgement ignores efficiency all together in focussing on ‘wrongs’ and ‘just’ compensation. We consider legal developments in the UK and US to show (i) efficient breach and gain-based disgorgement can be reasonably reconciled; (ii) a full disgorgement remedy will be evaded because the defendant will deliver specific performance; (iii) careful recognition of the type of externalities affecting the plaintiff, defendant and third parties indicates when disgorgement is useful.

Abstract
Conductive flexible polypyrrole-silver (PPy-Ag) composite films were prepared on Biaxial Oriented Polyethylene Terephthalate (BOPET) substrate with surfaces treated by (3-aminopropyl) trimethoxysilane (APTMS). The surface treatment was carried out to improve the adhesion, morphology, and electrical properties of the deposited film to enhance the Electromagnetic Interference Shielding Effectiveness (EMI-SE). APTMS grafting on the BOPET substrate was confirmed by X-ray Photoelectron Spectroscopy (XPS) and Atomic Force Microscopy (AFM) analyses. All structural, morphological, and electrical features of PPy-Ag raised from different AgNO3 molar ratio were investigated. The shielding effectiveness properties, experimentally determined for the synthesized PPy-Ag films were compared to those simulated analytically and numerically based on the transmission line matrix method (TLM). Both analytical and numerical models showed a good agreement with experimental measurements. The obtained results confirmed that the PPy-Ag films of 0.5 M/1 M molar ratio exhibits high EMI shielding performance of about 21 dB along with an electrical conductivity of 47 S/cm. Therefore, the treated surface flexible PPy-Ag films can be considered as potential candidate for high frequency electromagnetic interference shielding applications.

Abstract
Real estate markets have been all but neglected by historical research. Following a workshop held in Bielefeld in September 2019, this volume seeks to contribute to a better understanding of their characteristics. The introduction starts out with a definition of some key concepts. It then summarizes the state of historical research and argues for a focus on the social and institutional embeddedness of real estate markets. The introduction also gives an outline of the individual papers and a brief summary of some overall findings.
Financial Markets and Land Redistribution in 19th Century East Prussia
Authors: Wandschneider Kirsten 
Published: May 2022

Abstract
How did the emerging market for land in the 19th century influence land distribution in East Prussia? And how did land markets respond to the emergence of financial institutions that relied on land as collateral but also affected the ease and speed of land transfer?
Focusing on the example of a specific financial institution – the East Prussian Landschaft – this paper empirically tests the hypothesis that the Landschaft credit institutes, through their provision of privileged credit, enabled noble estates to expand their landholdings. It also tests whether the existence of Landschaft-credit helped noble estates to remain in the hands of nobles and halted estate sales to the emerging bourgeoisie. The analysis combines several datasets on East Prussian landed estates in 1796, 1834 and 1882 and matches these with borrowing records of the East Prussian Landschaft from 1823 and 1829. The study finds that access to Landschaft-credit correlates positively with estate size over the 19th century, suggesting that the Landschaft credit institutes did play a role in ownership concentration. The results regarding the transfer of estates from the nobility to the bourgeoisie show a weaker link between Landschaft-credit and ownership status of estate holders.
Mass Weddings, Baby Boom and Full Employment?
Authors: Somcutean Cristina 
Published: May 2022

Abstract
In 1933, the German government introduced the marriage loan for newlyweds, a policy aimed at increasing marriages and births as well as male employment, which entailed a work ban for the wife and sizeable credit deductions for children. This paper illustrates that the policy was rather ineffective based on a critical evaluation of the existing literature on the topic, how the policy was implemented in practice, as well as a correlation and interrupted time series analysis and consideration of the historical context of the period between 1925 and 1939. This result starkly contrasts to the substantial changes expected at the time of the introduction. In theory, only a small fraction of newlyweds was eligible for the loan. In practice, the development of marriages postintroduction significantly differed from the period prior to the policy, but causation is unclear. While births increased, this can be attributed to a combination of policies and the improved economic environment compared to the crisis years. The sharp decrease in unemployment probably resulted from the introduction of several targeted policies and embellishment of unemployment statistics.
