The study focuses on chigger mites parasitizing bird hosts in three countries of Latin America, Costa Rica, Paraguay, and Peru. In total, 785 chiggers collected from 145 birds of 67 species have been identified. Three new species have been described: Eutrombicula talamancensis sp. nov., from ten bird species in Costa Rica, Eutrombicula cathari sp. nov., from two species of the genus Catharus Bonaparte, 1850 in Costa Rica, and Eutrombicula gonzalezi sp. nov., from three bird species in Paraguay. Eutrombicula helleri (Oudemans, 1911), considered as a synonym of Eutrombicula goeldii (Oudemans, 1910) since 1949, has been restored as a separate species. Re-descriptions of E. helleri, E. goeldii, and Eutrombicula pacae (Floch and Fauran, 1957) have been provided based on new materials. Five species have been for the first time recorded in Paraguay, four in Peru, and two in Costa Rica. Five species have been for the first time recorded on bird hosts. Data on a geographic morphometric variability of E. helleri and Blankaartia sinnamaryi (Floch and Fauran, 1956) have been provided. Co-occurrence of two (three, in one case) chigger species on one host individual has been recorded in 17% of birds.

Authors: Abreu Roberto L. , Townsend Diamonique , Mitchell Y’Londa , Ward Jessica , Audette Lillian , Gonzalez Kirsten A.
Published: May 2022

Given that qualitative and mixed methods have been used to address social justice issues, counseling psychologists have been drawn to these research designs to advance knowledge in the field. However, qualitative and mixed methods are rarely used in counseling psychology to examine the experiences of LGBTQ individuals. This content analysis reviewed all qualitative and mixed methods studies conducted with LGBTQ individuals between 2009 and 2019 in three leading counseling psychology journals. Results from 24 studies revealed: (a) an increase in LGBTQ-related topics; (b) an overreliance in grounded theory as a research design, diverse analytical approaches, overreliance on semi-structure interviews, and increased disclosure of reflexivity and trustworthiness; and (c) an overwhelming representation of White, cisgender, gay and lesbian, middle class, college educated, English-speaking, Christian, mainland United States residents. We pose a call to action for the next decade of qualitative and mixed methods research with LGBTQ individuals in counseling psychology.
Understanding the Role of Academic Vocabulary in Content Acquisition for Middle School Students With and Without Disabilities
Authors: Wang Hsuan-Hui , Swanson Elizabeth , Vaughn Sharon
Published: May 2022

Vocabulary is a prominent contributor to reading comprehension. However, little is known about how students with disabilities with lower vocabulary performance respond to Tier 1 instruction, or how their vocabulary knowledge relates to their content acquisition. To examine the differential impact of Tier 1 instruction for U.S. middle school students with disabilities and to investigate the relations among academic vocabulary, content knowledge, and reading comprehension, this study analyzed data collected in previous randomized controlled trials. Findings suggest that evidence-based Tier 1 instruction targeting academic vocabulary can help eighth graders with disabilities grow as much as students without disabilities on academic vocabulary and content reading comprehension. In addition to students’ baseline performance, learning gains in academic vocabulary significantly predicted the growth of content acquisition among students with disabilities.
Ontologies on collision course: Collaborative mobility v. managerial transport in the contemporary history of intelligent transport systems
Authors: Normark Daniel
Published: May 2022

Is mobility ontologically different than transport? This essay contributes to this contentious question by looking at the frictions and failures of merging intelligent transport systems (ITS) with mobile information and communication technologies (mobile-ICT). Adopting a methodological approach from science and technology studies (STS), which focus on (political) ontologies, enables us to follow the ordering practices and constituent elements participating in the enactment of multiple ontologies. The dissonance between ITS and mobile-ICT can thus be regarded as the enactment of two ontologies, one managerial and one collaborative. The tensions between these traditions enable us to articulate the differing institutions and sensibilities that characterise a managerial and a collaborative ontology. Thus, how we approach transport can be understood either as under the spell of managerial functionality or as collaboratively achieved pending on “what is” transport. By looking at frictions when defining ITS, we can identify two ontologies that have existed within the history of transport, traffic and mobility.
The duty to provide after-care under section 117 of the Mental Health Act 1983 again
Authors: Andoh Benjamin
Published: May 2022

In December 2021 the Court of Appeal (Civil Division) published its ruling in Worcestershire County Council, R (On the Application Of) v Secretary of State for Health and Social Care [2021] EWCA Civ 1957, a case about a dispute between two local authorities regarding which of them should bear the duty to provide after-care for a patient (service user) following her discharge from her second detention under section 3 of the Mental Health Act 1983. The primary issue in the case was where she was ordinarily resident at the time of her second detention under s 3 of the Mental Health Act 1983. This paper reviews the case, surveys the evolution of the duty to provide after-care and comments on specific aspects of the Court of Appeal’s decision.
Effect of co-electrospinning system on morphology and oil adsorption of helical nanofibers
Authors: Teng Defang , Zeng Yongchun
Published: May 2022

In this study, inspired by cucumber tendrils, nanofibers with helical morphology are fabricated in co-electrospinning systems with different spinneret configurations. Poly(m-phenylene isophthalamide) (Nomex) and thermoplastic polyurethane are chosen as the two components in co-electrospinning. Using simulation and experimental methods, the electric field distribution and the morphology of nanofibers from the three co-electrospinning systems are analyzed. The helical nanofibers generated from the off-centered spinneret co-electrospinning system possess a helical shape with larger curvature and show higher tensile strain. In addition, the helical nanofibers show an oil adsorption capacity up to 79.3 g g−1 and high oil retention (91%). This study may help control helical fiber morphology and extend the applications of helical materials.

Published: May 2022

Objective: Lung adenocarcinoma (LUAD) is a common malignant tumor with a poor prognosis. The present study aimed to screen the key genes involved in LUAD development and prognosis. Methods: The transcriptome data for 515 LUAD and 347 normal samples were downloaded from The Cancer Genome Atlas and Genotype Tissue Expression databases. The weighted gene co-expression network and differentially expressed genes were used to identify the central regulatory genes for the development of LUAD. Univariate Cox, LASSO, and multivariate Cox regression analyses were utilized to identify prognosis-related genes. Results: The top 10 central regulatory genes of LUAD included IL6, PECAM1, CDH5, VWF, THBS1, CAV1, TEK, HGF, SPP1, and ENG. Genes that have an impact on survival included PECAM1, HGF, SPP1, and ENG. The favorable prognosis genes included KDF1, ZNF691, DNASE2B, and ELAPOR1, while unfavorable prognosis genes included RPL22, ENO1, PCSK9, SNX7, and LCE5A. The areas under the receiver operating characteristic curves of the risk score model in the training and testing datasets were .78 and .758, respectively. Conclusion: Bioinformatics methods were used to identify genes involved in the development and prognosis of LUAD, which will provide a basis for further research on the treatment and prognosis of LUAD.
The Cult of the Irrelevant or Political Narrative?
Authors: Schiff Rebecca L.
Published: May 2022

This commentary discusses Michael Desch’s book The Cult of the Irrelevant: The Waning Influence of Social Science on National Security. Desch offers a respectable and important overview of the history of national security within the social sciences from World War I through current times. He focuses on the gradual irrelevancy of political science and particularly the field of international security. Desch, however, neglects the recent university activism and political narratives infusing academic writings and classroom discussions. This review argues that what contributes to the irrelevancy of social science and particularly national security is the new “cult” itself: demands placed on academia and students to become political activists, and not social scientists nor theorists who contribute rigorous academic research affecting domestic and foreign policy. It is the political advocacy narrative itself, embraced by university cultures, that pushes social science and the study of national security down the path of irrelevancy.
Construction of a Research Requirement Participant Pool Using Open-Source Software
Authors: Westfall Jonathan E. , Hill Evan M.
Published: May 2022

Introduction

Recruiting undergraduate students to participate in research has long been an established practice within psychology. Although this data source has weaknesses, this involvement in the research process has considerable pedagogical value in teaching students research methodology.

Statement of the Problem

Most common software packages used to manage participant pools tend to be expensive, to the extent that it prohibits access for small institutions and departments.

Literature Review

Highlighting the problem, we cite research related to using undergraduates as participants, pedagogical value of these experiences, and current trends in software distribution. We then provide evidence of successful implementation of open-source software (OSS) in educational settings, and conclude with OSS options capable of addressing the problem of access.

Teaching Implications

By providing students research experiences, both as a researcher and as a participant, we enhance their understanding of this process. Secondary to this, we can foster within them a skill set that is valuable to disciplines outside of academia.

Conclusion

The implementation of an OSS system to manage research participants provides a cost-effective means to expand the learning and research opportunities of available to students.
When Disaster Strikes! An Interdisciplinary Review of Disasters and Their Organizational Consequences
Authors: Gregg Heath R. , Restubog Simon Lloyd , Dasborough Marie , Xu Changmeng (Melody) , Deen Catherine Midel , He Yaqing
Published: May 2022

Disasters (e.g., natural catastrophes, pandemics/epidemics, mass violence events, and human/technological errors) are becoming increasingly common due to factors such as growing population density and accelerated climate change. Exposure to any type of disaster is damaging for both individuals and organizations. Disasters deprive individuals of their livelihoods, alter how employees perform their work, and harm individual well-being. For organizations, disasters compromise functioning and profitability, often resulting in organizational failure. As a result, there is growing interest in research linking disaster events to the workplace. Based on an analysis of 260 disaster articles, we offer a comprehensive, systematic, interdisciplinary review of the disaster literature with organizational implications. Employing a resource-based perspective, embedded within an ecological systems framework, we suggest that disaster exposure depletes (or prompts investment of) individual, team, and organizational resources and subsequently impacts organizational outcomes. This theoretical framework can be used to identify the critical research gaps that exist in the literature and offers a promising agenda for future research.
An Exploratory Investigation on Exposure, Perception and Patterns of Usage of Digital Technology among Children in a North Indian City
Authors: Tripathi Madhvi , Mishra Shailendra Kumar
Published: May 2022

Background: Digital technologies such as smartphones, tablets and laptops have become a mainstay part of nearly every household and are gradually being integrated into the lives of both adults and children. We aim to determine the extent of exposure and usage of digital technology by children in their daily activities and to understand the transition in technological preferences and attitudes over the generation. Methods: A cross-sectional study was conducted on 400 children (both boys and girls) aged 05-12 years living in Prayagraj city of Uttar Pradesh, India, using a pretested interview schedule. Descriptive and bivariate statistics were used for data analysis. The phenomenological method was used to understand respondents’ viewpoints about their preferences and attitudes related to technology. Results: An overwhelming majority of households have television (TV) followed by digital cameras, laptops, tablets, kindle and video games such as Playstation. Nearly half of children began to use digital devices from the age of 7 to 8 years. Nearly two-third of the children learnt to use digital devices on their own, and about 12% of them reported often practicing media multitasking. Over the generation, differences are noted in terms of possession, use and perception regarding digital technology. Conclusion: The availability of media content on such devices influences the screen time of children of all ages. The study underscores the importance of parental monitoring and devising a policy to regulate the ownership of digital devices and to reduce screen time to less than two hours per day, especially during early childhood.
Intraoperative use of noninvasive ventilation during spinal anaesthesia in patients with severe chronic obstructive pulmonary disease undergoing orthopaedic surgery: A case report

Published: May 2022

Compared with invasive mechanical ventilation, noninvasive ventilation (NIV) improves patient comfort and neurocognitive function; and reduces the likelihood of nosocomial infections and the need for sedation. NIV can also be used perioperatively to prevent postoperative pulmonary complications. This current report describes a case of a 64-year-old female patient with chronic obstructive pulmonary disease and chronic respiratory failure that underwent spinal anaesthesia during surgery. She was sedated with propofol. She brought her home ventilator equipment to the operating room and it was used in biphasic-positive airway pressure mode for immediate treatment of respiratory depression.
The Lady and the Gentleman: Changing Gender Relations and Anxieties in Early Malayalam Cartoons
Authors: Ali Nassif Muhammed
Published: May 2022

Kerala, towards the end of the nineteenth century, witnessed an awakening which left impressions on all the walks of the society. The advent of modernity, which was triggered by the British rule as well the state’s attempt to widen education and welfare measures, initiated reform movements among almost all the communities. The accessibility to modern education and resultant exposure to scientific, philosophic and humanistic values as well as ideas such as liberty, equality, secularism and individualism changed the perception of men and women towards the society and towards the self.

This also resulted in the formation and spread of media and journalism, which in turn led to the rise of humour magazines and eventually, cartoons in Malayalam. However, the perception of these media and medium towards the other aspects of modernity was quite complex to say the least.

The western educated woman and man, it can be found, have been featured in quite a number of cartoons across magazines. The article, therefore, focuses on the representations of changing gender relations in the Malayali society through cartoons published in humour magazines ( Sanjayan, Vishwaroopam, Naradar and Sarasan) from late 1930s to 1960s. Starting with Sanjayan, these cartoons targeted the ‘modern’ women and men, albeit in different ways. Those on women lampooned their emancipation, education, access to the public sphere etc. and its perceived effect on the sociocultural setup, especially within and in relation to the institutions of marriage and family. On the other hand, men were ridiculed for their westernisation and emasculation.
Why do voters elect less qualified candidates?
Authors: Mizuno Nobuhiro , Okazawa Ryosuke
Published: May 2022

Voters sometimes vote for seemingly less-qualified candidates. To explain this fact, we develop a political agency model with sequential elections in which a voter elects a politician among candidates with different competence (valence) levels, considering that politicians’ representation of voters’ preferences depends on their competence levels. We show that a negative relationship exists between politicians’ competence and their representation when a future challenger is likely to be incompetent and the reward for politicians is small. We also highlight voters’ private information on how they evaluate candidates’ competence, demonstrating that voters’ demand for incompetent candidates can be a self-fulfilling prophecy.
Stochastic optimal preview control response of a quarter-car nonlinear suspension model using spectral decomposition method
Authors: Gopala Rao LVV , Sharma Rakesh Chandmal , Satyanarayana VSV , Palli Srihari
Published: May 2022

This paper considers a two degree of freedom quarter-car model of a four wheel vehicle with nonlinear spring travelling at a constant speed on a random road surface with a preview control to obtain the optimal vehicle response. The nonlinear spring behavior is assumed as a hysteresis and modelled by the Bouc–Wen model. This nonlinear vehicle model is linearized by using statistical linearization approach. The root mean square values of the control force, suspension stroke and road holding characteristics are determined by spectral decomposition method. The results obtained for the equivalent linearized model using the SDM are validated with Monte Carlo simulation, and the results show that the vehicle performs better using preview control.
Carbon emission from the electric power industry in Jiangsu province, China: Historical evolution and future prediction
Authors: Zhang Chenjun , Ma Teli , Shi Changfeng , Chiu Yung-Ho
Published: May 2022

This paper takes Jiangsu as an example to measure the carbon emissions from the electric power industry from 2002 to 2017, builds an extended STIRPAT model to quantify its driving factors, and uses the Monte Carlo method to simulate the evolution of carbon emissions in multiple scenarios from 2018 to 2030. The results show that: (1)Population scale, urbanization level, GDP per capita, industrial added value, and electricity consumption intensity promote the increase of carbon emissions in the electric power industry. (2)Trade openness and the transmission level of other provinces play a role in reducing carbon emissions. (3)Under the baseline scenario and the green development scenario, the carbon emissions of the electric power industry have shown a continuous growth trend, but the growth rate of carbon emissions has slowed down significantly under the green development scenario.
Examining the asymmetric link between clean energy intensity and carbon dioxide emissions: The significance of quantile-on-quantile method
Authors: Shahzad Farrukh , Fareed Zeeshan , Wan Yong , Wang Yihan , Zahid Zohaib , Irfan Muhammad
Published: May 2022

This study corroborates the asymmetric and heterogeneous associations between clean energy intensity (CEI) and carbon dioxide (CO2) emissions among the world's top ten renewable energy consumer countries using quarterly data from 1970Q1 to 2018Q4. We quantify the complete dependence structure between CEI and CO2 at quantile distributions using a novel quantile-on-quantile (QQ) method proposed by Sim and Zhou (2015). Compared to classic approaches such as quantile regression and ordinary least squares, the QQ technique can provide more information on the overall relationship between CEI and CO2. Furthermore, we also seek to determine causal relationships between CEI and CO2 using a quantile Granger causality approach suggested by Troster. According to our empirical evidence, the link between the two variables is predominantly negative. Moreover, there are significant disparities across countries in the quantile ranges of CEI and CO2. In particular, there is a weak positive link between CEI and CO2 in the case of Sweden, Italy, Japan, and Australia, which may be because CEI has a minimal direct influence on CO2 in these countries. The empirical findings clarify that policymakers should fund renewable energy industries to minimize carbon dioxide (CO2) emissions and achieve Sustainable Development Goals (SDGs).
Path-specific effects in the presence of a survival outcome and causally ordered multiple mediators with application to genomic data
Authors: Tai An-Shun , Lin Pei-Hsuan , Huang Yen-Tsung , Lin Sheng-Hsuan
Published: May 2022

Causal multimediation analysis (i.e. the causal mediation analysis with multiple mediators) is critical for understanding the effectiveness of interventions, especially in medical research. Deriving the path-specific effects of exposure on the outcome through a set of mediators can provide detail about the causal mechanism of interest However, existing models are usually restricted to partial decomposition, which can only be used to evaluate the cumulative effect of several paths. In genetics studies, partial decomposition fails to reflect the real causal effects mediated by genes, especially in complex gene regulatory networks. Moreover, because of the lack of a generalized identification procedure, the current multimediation analysis cannot be applied to the estimation of path-specific effects for any number of mediators. In this study, we derive the interventional analogs of path-specific effect for complete decomposition to address the difficulty of nonidentifiability. On the basis of two survival models of the outcome, we derive the generalized analytic forms for interventional analogs of path-specific effects by assuming the normal distributions of mediators. We apply the new methodology to investigate the causal mechanism of signature genes in lung cancer based on the cell cycle pathway, and the results clarify the gene pathway in cancer.
Anti-Müllerian hormone as a diagnostic tool to identify queens with ovarian remnant syndrome
Authors: Flock Ulrike , Fischer Stine , Weeger Jasmin , Reese Sven , Walter Beate
Published: May 2022

Objectives

Ovarian remnant syndrome (ORS) is suspected when heat signs occur in spayed individuals, but further diagnostic procedures are necessary to exclude other possible oestrogen sources, such as the adrenal gland or exogenous supplementation. Anti-Müllerian hormone (AMH), secreted by granulosa cells or Sertoli cells, serves to differentiate sexually intact from gonadectomised animals and has been described in dogs as a tool for diagnosing ORS. The aim of this study was to evaluate if AMH determination can be used to diagnose ORS in cats.

Methods

AMH was measured with a chemiluminescence immunoassay in serum samples of 15 sexually intact, 9 spayed and 16 cats with a history of heat signs after spaying. Abdominal ultrasound (n = 13), vaginal smears (n = 7), progesterone measurement (n = 5) and laparotomy (n = 14) were used to determine the presence of ovarian tissue. After surgery, a histological examination of the obtained tissue was performed in the cats with suspected ORS.

Results

In 15 cats with ORS the AMH serum concentrations were significantly higher than in spayed cats (n = 10; P = 0.025) and significantly lower than in sexually intact cats (n = 15; P = 0.001). Among the cats with ORS, the highest AMH serum concentrations were measured in the queens with cystic ovarian alterations and in one cat from which a whole ovary was obtained. The cat with the lowest AMH serum concentration had a simultaneous high progesterone serum concentration. Cats with ORS did not show any heat signs after surgical removal of the ovarian tissue.

Conclusions and relevance

A single determination of AMH in blood serum is a useful diagnostic tool for the diagnosis of ORS in cats, regardless of the hormonal activity of the remnant ovarian tissue.
Symmetries of Touch: Reconsidering Tactility in the Age of Ubiquitous Computing
Authors: Ladewig Rebekka , Schmidgen Henning
Published: May 2022

Engaging with the specific ways current media technologies interact with, or directly access the human body, we suggest developing a ‘symmetrical’ theory of touch. Critically referring to Bruno Latour’s invocation of ‘symmetrical anthropology’, we reconsider tactile agency as ‘technological agency’, arguing that the concept of touch – traditionally viewed as an exclusively human ability – should be extended to non-human actors and analysed in view of the cultural logic of capitalism. Its systematic focus, then, is on the productive intersections and contact zones between biology and technology: from phenomena of non-human touch in industrial production (lathing, printing, etc.) to the material touching taking place in the instrumental grasp on the living in the 19th-century physiological laboratories and the invisible operations of tracing, tracking and sensing taking place in the technological milieus of today’s (media) environments. In highlighting the tactile dimension of digital modernity and its economic genealogies, this article aims to advance a combined concept of human and non-human touch which provides a crucial angle for reconsidering bodies and technologies in the age of ubiquitous computing.
Fault diagnosis of rolling bearing based on singular spectrum analysis and wide convolution kernel neural network
Authors: Zhu Rui , Wang Mingxin , Xu Siyu , li Kai , Han Qingpeng , Tong Xin , He Keyuan
Published: May 2022

Research on bearing fault diagnosis generally uses a single signal processing method to extract features to a certain extent and then empirically judges the fault type at this stage. However, this approach has a poor fault feature extraction effect when the noise interference signal is large and subjective human errors. The diagnosis effect is determined by external interference and has no practical value. This paper proposes a rolling bearing fault diagnosis method based on singular spectrum analysis and a wide convolution kernel neural network, which can effectively extract the fault features of the rolling bearing crack fault signal with a strong noise interference and realize the efficient diagnosis of this kind of fault. Gaussian white noise is added to the standard bearing fault signal to construct the vibration signal with noise interference. Then, the noisy one-dimensional time series signal is preprocessed, including the data division into the training and test sets and the different kinds of numbering processing. Singular spectrum analysis is performed on the preprocessed data. Then, the denoised training set is used as input in a deep convolution neural network with a wide convolution kernel for feature extraction and model training. The trained diagnosis model is used for the fault prediction of the next test set, and the relevant diagnosis results are output. The test results show that this method can ensure the overall accuracy of more than 90% under the background of high noise, and the diagnosis rate of the model under various working conditions is stably maintained at more than 93%, without the collapse of diagnosis stability under the sudden change of noise. The advantages of model diagnosis efficiency and structural improvement fit are prominent.
Adaptive Autoregressive Modelling Based Structural Health Monitoring of RC Beam-Column Joint Subjected to Shock Loading
Authors: Rajeev Anupoju , Pamwani Lavish , Ojha Shivam , Shelke Amit
Published: May 2022

In the present work, a novel technique based on the combination of singular spectral analysis (SSA) and recursive estimate of coefficients of adaptive autoregressive (AR) modelling is employed to identify the damage in the reinforced (RC) beam-column joints. The damage is induced by imparting shock load at the tip of the beam-column joints. The damage is identified with the help of the acceleration response of the healthy and damaged specimens excited by high intensity white noise. The proposed approach has two major components, first, filtering and removing the noise from the dynamic response using the singular spectral analysis and second, modelling the filtered response using adaptive AR process to get the recursive estimate of coefficient matrix for baseline and damage states. The coefficients evaluated for each time instant are presented in a multi-dimensional subspace to form distinct clusters corresponding to a healthy and damaged state. In order to identify and quantify the damage, the geometrical and statistical measures are evaluated that quantifies the segregation of clusters. In total, three distinct measures are used to quantify the damage, namely, Euclidean distance (ED), Mahalanobis distance (MD) and Bhattacharyya distance (BD). The BD accounts the variation in the distribution of both the clusters, thereby shows superior results comparatively than ED and MD. The results of DSFs also manifest the superiority of BD over the other two DSFs. These geometrical and statistical distances are the damage sensitive feature (DSF) to identify and quantify the damage in the specimen due to the shock load. The obtained results of all the DSFs show good consistency with the maximum deformation of the specimen due to shock loading highlighting the accuracy of the proposed algorithm.
Bayesian approaches for critical velocity modelling of data from intermittent efforts
Authors: Peng Ken , Clarke Dave C , Swartz Tim B
Published: May 2022

In sports science, critical power and related critical velocity models have been widely investigated, and are being increasingly applied to field-based team sports. A challenge associated with these models is that laboratory experiments that yield accurate measurements of maximal sustainable velocity are expensive. Alternatively, inexpensive field data (from training and matches) are being used to fit such models. However, the intermittent nature of efforts in field-based sports implies that the dependent variable concerning maximum sustainable velocity is reliably calibrated only for short time durations. This paper develops methods where field data based on short time durations is combined with prior knowledge to fit the three-parameter critical velocity model. This is accomplished in a Bayesian framework for which Markov chain methods are required for model fitting and inference.
Circ_0066881 targets miR-144-5p/RORA axis to alleviate LPS-induced apoptotic and inflammatory damages in human periodontal ligament cells
Authors: Li Qin , Hu Zhaopeng , Yang Fang , Peng Yi
Published: May 2022

Circular RNAs (circRNAs) are involved in the regulation of various diseases, including periodontitis. The objective of this study was to analyze the biological role and regulatory mechanism of circ_0066881 in LPS-induced periodontal ligament cells (PDLCs). Circ_0066881, microRNA-144-5p (miR-144-5p) and retinoid acid-related orphan receptor A (RORA) levels were determined using reverse transcription-quantitative PCR (RT-qPCR) assay. Cell viability detection was performed by Cell Counting Kit-8 assay. Cell apoptosis was assessed through flow cytometry and caspase-3 activity assay. The protein analysis was completed via Western blot. Inflammatory cytokines were measured by ELISA. The target interaction was validated by dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. The level of circ_0066881 was down-regulated in periodontitis tissues. Overexpression of circ_0066881 relieved LPS-induced cell viability inhibition and apoptosis or inflammation promotion in PDLCs. Circ_0066881 could bind to miR-144-5p. The protective function of circ_0066881 was achieved by sponging miR-144-5p in PDLCs. Circ_0066881 acts as a miR-144-5p sponge to mediate the RORA level. Inhibition of miR-144-5p attenuated LPS-induced cell injury via targeting RORA. All these results demonstrated that circ_0066881 partly prevented LPS-evoked cell dysfunction in PDLCs through miR-144-5p-mediated up-regulation of RORA.

A retrospective review of a large commercial claims database was performed to identify patients who underwent primary operative management for Achilles tendon rupture between 2007 and 2016. The primary outcome measures of the study were risk factors for (1) postoperative complications, (2) revision surgery, and (3) increased healthcare resource utilization.

Results:

A total of 50,279 patients were included. The overall complication rate was 2.7%. The most common 30-day complication was venous thromboembolism (1.2%). The rate of revision surgery was 2.5% at 30 days and 4.3% at 2 years. Independent risk factors for 30-day complications in our cohort included increasing age, hyperlipidemia, hypertension, female sex, obesity, and diabetes. Independent risk factors for revision surgery within 2 years included female sex, tobacco use, hypertension, obesity, and the presence of any postoperative complication. The average 5-year cost of operative intervention was $17,307. The need for revision surgery had the largest effect on 5-year overall cost, increasing it by $6776.40. This was followed by the presence of a postoperative complication ($3780), female sex ($3207.70), and diabetes ($3105).

Conclusion:

Achilles tendon repair is a relatively low-risk operation. Factors associated with postoperative complications include increasing age, hyperlipidemia, hypertension, female sex, obesity, and diabetes. Factors associated with the need for revision surgery include female sex, hypertension, obesity, and the presence of any postoperative complication. Female sex, diabetes, the presence of any complication, and the need for revision surgery had the largest added costs associated with them.

Clinical Relevance:

Surgeons can use this information for preoperative decision-making and during the informed consent process.
Beyond manifestos: Exploring how political campaigns use online advertisements to communicate policy information and pledges
Authors: Dobber Tom , Vreese Claes de

Social media platforms take on increasingly big roles in political advertising. Microtargeting techniques facilitate the display of tailored advertisements to specific subsegments of society. Scholars worry that such techniques might cause political information to be displayed to only very small subgroups of citizens. Or that targeted communication about policy could make the mandate of elected representatives more challenging to interpret. Policy information in general and pledges, in particular, have received much scientific scrutiny. Scholars have focused largely on party manifestos, but policy information and pledges communicated via online advertisements offer a new arena with new dynamics. This study uses Facebook’s ad library to describe how Dutch political campaigns advertise policy information and pledges in the run-up to the 2019 European Elections. The results show that much policy information is displayed to small subsegments of society. These findings provide evidence for concerns about pledge obfuscation, voter manipulation and mandate interpretation.
Justify Your Alpha: A Primer on Two Practical Approaches
Authors: Maier Maximilian , Lakens Daniël
Published: May 2022

The default use of an alpha level of .05 is suboptimal for two reasons. First, decisions based on data can be made more efficiently by choosing an alpha level that minimizes the combined Type 1 and Type 2 error rate. Second, it is possible that in studies with very high statistical power, p values lower than the alpha level can be more likely when the null hypothesis is true than when the alternative hypothesis is true (i.e., Lindley’s paradox). In this article, we explain two approaches that can be used to justify a better choice of an alpha level than relying on the default threshold of .05. The first approach is based on the idea to either minimize or balance Type 1 and Type 2 error rates. The second approach lowers the alpha level as a function of the sample size to prevent Lindley’s paradox. An R package and Shiny app are provided to perform the required calculations. Both approaches have their limitations (e.g., the challenge of specifying relative costs and priors) but can offer an improvement to current practices, especially when sample sizes are large. The use of alpha levels that are better justified should improve statistical inferences and can increase the efficiency and informativeness of scientific research.
Exploring SWPBIS Implementation Outcomes in Rural and Urban Schools in Florida

Rural schools experience unique challenges, including teacher quality and teacher retention, limited resources, and availability of funding. Furthermore, access to professional development and, subsequently, implementation of evidence-based practices may also be limited in rural settings. One evidence-based framework for implementing evidence-based practices, School-Wide Positive Behavioral Interventions and Supports (SWPBIS), has been widely implemented, including in rural and urban schools. Yet, very little research has explicitly compared rural and urban schools implementing SWPBIS with regard to implementation and discipline. Therefore, we examined statewide data to evaluate differences between rural and urban schools implementing SWPBIS in Florida. We found that both rural and urban schools were equally likely to implement all the components of SWPBIS. When comparing schools, we found that rural schools implementing SWPBIS had more out-of-school suspensions than nonimplementing rural schools, while the opposite was true for urban schools. Limitations and future research are discussed.
Scenicite, a new uranyl-sulfate mineral from the White Canyon district, San Juan County, Utah, USA

The new mineral scenicite (IMA2021-057), [(UO2)(H2O)2(SO4)]2⋅3H2O, was found in the Green Lizard, Giveaway–Simplot, Markey and Scenic mines, White Canyon district, San Juan County, Utah, USA, where it occurs as a secondary phase on granular quartz matrix in association with various combinations of deliensite, gypsum, natrozippeite, rietveldite and shumwayite. Scenicite crystals are transparent, light green yellow, poorly formed blades or prisms, up to 0.1 mm in length. The mineral has white streak and vitreous lustre. It exhibits bright greenish-white fluorescence (405 nm laser). It is brittle with irregular, curved fracture and a Mohs hardness of ~2. It has excellent {100} and good {001} cleavages. The calculated density is 3.497 g cm–3. Optically, the mineral is biaxial (–) with α = 1.556(2), β = 1.573(2), γ = 1.576(2) (white light); 2V = 45(3)°; extreme r < v dispersion; orientation: X = c, Y = a, Z = b; pleochroism: X and Y = colourless, Z = light green–yellow; and X = Y < Z. The Raman spectrum exhibits bands consistent with UO22+, SO42– and O–H. Electron microprobe analysis provided the empirical formula U1.996S2.005O19H13.997. The five strongest powder X-ray diffraction lines are [dobs Å(I)(hkl)]: 7.69(70)(201), 5.63(100)(111), 4.92(84)(202,310), 4.80(93)(401) and 3.398(55)(020,120,511,601). Scenicite is orthorhombic, Pca21, a = 21.2144(15), b = 6.8188(3) c = 11.2554(6) Å, V = 1628.18(16) Å3 and Z = 4. In the structure of scenicite (R1 = 0.0365 for 1259 I > 2σI), linkages of pentagonal bipyramids and tetrahedra form an infinite neutral [(UO2)(SO4)(H2O)2] chain. The structure of shumwayite contains topologically identical chains.

Introduction

Emergent cricothyrotomy (EC) is a rare and lifesaving procedure to secure a difficult airway when other methods have failed. Many techniques have been discussed in the literature. This study aimed to identify major techniques used to perform EC in a regional trauma center and evaluate outcomes associated with the techniques.

Methods

Patients who underwent EC at Arrowhead Regional Medical Center between 1-1-2009 and 1-1-2019 were reviewed for eligibility for this study. Patients’ data were extracted from the trauma database. Chi-square tests were conducted to assess the difference on variables between the techniques.

Results

A total of 51 (0.17%) of these patients required EC and were included in the database. The two most prevalent techniques were the scalpel-bougie-tube (SBT) and the surgical cricothyrotomy technique (SCT). More than half (n = 27, 52.9%) of the cohort received the SBT. There was no statistically significant difference between the two techniques with regards to demographic variables, including age (p = 0.7528), injury severity score (ISS, p = 0.896), gender (p = 0.3709), and race (p = 0.8935). However, the SCT group had a statistically higher Glasgow Coma Scale (GCS) than the SBT group (p = 0.0036). There was no statistically significant difference in mortality or complications between these two groups (p = 0.2172 for mortality).

Discussion

Two techniques of EC were identified as preferred techniques. Both procedures were successful in securing an emergency airway, noting a difference in the time to completion of the two techniques. Given the rarity of the procedure, practitioners may choose the method based on their training and the availability of appropriate instruments.
