Enhanced performance of long-term evolution small-cell networks using improved mobility algorithms
Authors: Al-Amodi Abdullah Mohammed Abdullah , Datta Amlan , Obaid Abdulrahman Mohammed Hussain
Published: May 2022

With an ever-increasing number of user equipment (UE) and bandwidth demands of new applications, the deployment of dense heterogeneous cellular networks has been adopted in many network scenarios. The small cells are unable to unload the traffic due to the random UEs mobility and cells deployment. This degrades the network performance such as handover success, throughput, and load distribution. To address such a problem, we propose an enhanced mobility load-balancing algorithm for small cells. The conventional mobility load balancing (MLB) algorithms study only the fixed or adaptive thresholds of the network separately to consider the load balance process, while other MLB algorithms consider the neighboring cells of the network those experience unnecessary MLB actions. The proposed load balancing algorithms study overloaded cells and neighbors using the proposed efficiency parameter, B. To identify the overloaded cells, we propose B which compares between a pre-defined threshold and the network threshold to categorize medium and overloaded cells, based on B, the algorithm is triggered. Then, to control the shifted load to a target neighbor cell, we propose the Rescue factor, f. the f ensures the load of the target cell after handover is equal or less than Ɓ. The simulation results showed a lower standard deviation and higher throughput and physical resource block utilization than surveyed algorithms.

A good antenna design has played an essential role in the design of wireless communication systems, international companies are looking for the best design that suits their products in terms of size, bandwidth, gain, cost, and performance. In this paper, three antenna models are designed for fifth-generation (5G) communications, the first model is a single antenna, the second model is a two-ports multi-input multi-output (MIMO) antenna, and the third model is a four-ports MIMO antenna. The geometric dimensions of a single antenna are 20×37×1.6 mm3, the two-ports antenna dimensions are 44×37×1.6 mm3, while the four-ports antenna dimensions are 74×44×1.6 mm3. The design of these antennas was based on the latest strategies in terms of their small sizes and operating from 13.5 to 20 GHz in wide and multiple bands to be compatible with all advanced communication devices. Based on the results that emerged, it was noted that the reflection coefficient (S11) < -10 dB and has better isolation between the ports is < -26 dB. While the envelope correlation coefficient (ECC) value is < 1.036×10-9, and the diversity gain (DG) value is 10 dB. All antennas proposed operate in ultra-wideband (UWB) which is very necessary for 5G communications devices.
Mulheres-Onça: mitologia, gênero e antropofagia no Complexo do Marico
Authors: Soares-Pinto Nicole
Published: May 2022

As narrativas mitológicas dos povos originários dos afluentes da margem direita do médio rio Guaporé revelam uma íntima conexão entre relações de gênero e a diferença humano/animal/espírito.  Enfatizam, por um lado, as condições de possibilidade de uma sociedade composta por relações de sexo oposto, e por outro lado, a “antropofagia” praticada pelas mulheres. A partir da articulação com a etnografia cotidiana, em particular referente à produção e consumo de bebida fermentada, o artigo sugere que a antropofagia feminina, i.e., a identificação virtual das mulheres com as onças, é a condição para a diferença (atual) que separa os humanos dos não-humanos e os humanos entre si.
Las casas como procesos colectivos. Reflexiones etnográficas sobre prácticas políticas de mujeres de la economía popular
Authors: Pacífico Florencia Daniela
Published: May 2022

En este artículo, propongo un análisis etnográfico de las conexiones entre procesos de construcción y reforma material de las casas y una serie de prácticas políticas colectivas protagonizadas por mujeres de sectores populares en el marco de la implementación de programas estatales y de la acción de organizaciones sociales. Planteo que la puesta en marcha de prácticas colectivas ejerce influencia sobre las casas, al tiempo que la materialidad de estos espacios y la posibilidad de transformarlos, pueden constituir una base relevante desde la cual construir modalidades de organización política y formas de militancia. Procurando contribuir a una reflexión más amplia acerca de los límites de aquello que definimos como político y tomando distancia de miradas duales, sostengo que las casas pueden ser pensadas como procesos políticos colectivos desde dónde se politizan asuntos comúnmente definidos como parte de la vida “privada” o “doméstica”.

Abstract P119: The 15-lipoxygenase-derived Oxylipins 15-HETrE And 15-HETE Inhibit Platelet Activation In Part Through Activation Of PPARs

Published: May 2022

Cardiovascular disease is the leading cause of mortality in the US annually. The underlying cause of mortality in cardiovascular disease is the formation of platelet-rich clots that occlude blood vessels due to aberrant platelet activation. While antiplatelet therapeutic intervention has significantly reduced the risk of an occlusive thrombotic event, many patients remain at risk for a myocardial infarction or stroke. The antiplatelet and antithrombotic effects of omega-6 polyunsaturated fatty acids are primarily attributed to its metabolism to bioactive metabolites by oxygenases such as lipoxygenases (LOX). LOXs are a group of lipid-peroxidizing enzymes named according to the specific position where they add an oxygen to arachidonic acid: 5-LOX, 12-LOX, and 15-LOX. Previous studies from our group have demonstrated that dihomo-γ-linolenic acid and arachidonic acid regulate platelet function through their respective 12-LOX-derived oxylipins, 12(S)-hydroxyeicosatrienoic (12-HETrE) and 12(S)-hydroxyeicosatetraenoic acid (12-HETE). While the expression of 15-LOX in platelets is controversial, platelets have demonstrated the ability to generate the 15-LOX-derived bioactive metabolites. In this study we sought to elucidate the mechanistic effects of 15(S)-hydroxyeicosatrienoic acid (15-HETrE) and 15(S)-hydroxyeicosatetraenoic (15-HETE) on platelet reactivity. Washed human platelets were treated with 15-HETrE or 15-HETE and platelet aggregation, integrin αIIbβ3 activation, calcium mobilization, and granule secretion were quantified. Both 15-HETrE and 15-HETE were shown to inhibit platelet aggregation mediated by collagen. In comparison to vehicle-treated platelets, treatment with 15-HETrE or 15-HETE inhibited agonist-induced intracellular signalling events, including PKC activation, calcium mobilization, and granule secretion. Surprisingly, while 15-HETrE was shown to inhibit platelets through a signalling cascade involving the activation of PPARβ, 15-HETE’s inhibitory effect was shown to involve the activation of PPARα and the inhibition of 12-HETE production. A better understanding of the effects of 15-LOX oxylipins in platelets could lead to the identification of novel antiplatelet therapies.
Abstract 13184: ATP Citrate Lyase a New Therapeutic Target for Vascular Remodeling Diseases

Vascular remodeling diseases (VRD) like coronary artery diseases or in-stent restenosis are characterized by proliferative and apoptosis-resistant vascular smooth muscle cells (VSMCs). As in cancer, proliferative VSMCs have increased Warburg effect leading to an impairment in the acetyl-coA homeostasis resulting in a profound epigenetic reprogramming sustaining their survival overtime. ATP citrate lyase (ACLY) is a key enzyme of the acetyl-coA and cholesterol metabolism involved in cell survival and resistance to apoptosis, in part by promoting the Warburg effect and histone acetylation. Surprisingly, its role in VRD remains unknown. We hypothesized that ACLY inhibition reverses VRD. Using immunofluorescence and western blot, we showed a significant (p<0.05) upregulation of ACLY in remodeled distal coronary arteries (n=5), stenosed saphenous vein (n=3) and remodeled radial arteries (n=5) isolated from patients with VRD compared to non VRD donors.
In vitro
, we found that PDGF/FGF2-stimulated human rings of mammary arteries, saphenous veins or cultured VSMCs isolated from coronary arteries exhibit increased expression as well as AKT-dependent activation and nuclear accumulation of ACLY (p<0.05). These effects were associated with a profound increase in cell proliferation (Ki67) and repression of apoptosis (Annexin V). Consistently, acetylation-dependent upregulation of the pro-proliferative markers PCNA, MCM2 and PLK1 (p<0.05) and the cell survival marker SURVIVIN was observed (p<0.05)). All these effects were dose-dependently inhibited by pharmacological inhibition of ACLY using BMS303141. Using a standard
in vivo
rat carotid injury model, we showed that the clinically available ACLY inhibitor ETC-1002 (n=10) prevents carotid remodeling 14 days post-injury compared to vehicle treated rats (n=10) (p<0.05). We demonstrated that ACLY upregulation in VRD is associated with vascular remodeling through increased smooth muscle cell proliferation and resistance to apoptosis.

Acly
smooth muscle cell-specific knockout mice are currently performed to further characterize the therapeutic potential of ACLY inhibition in VRD.

Western Pacific Premoistening for Eastward-Propagating BSISO and Its ENSO Modulation
Authors: Wei Yuntao , Liu Fei , Ren Hong-Li , Chen Guosen , Feng Chengfeng , Chen Bin
Published: May 2022

The boreal summer intraseasonal oscillation (BSISO) is a major source of subseasonal predictability of the East Asian summer monsoon. However, modeling and prediction of the BSISO remain major challenges partly due to an incomplete understanding of its eastward propagation. Our moisture budget analysis suggests that western Pacific (WPAC) premoistening leading the eastward-propagating (EP) BSISO is mainly attributed to the horizontal moisture advection with two centers in the lower and middle troposphere, respectively. The lower-tropospheric center is rooted in the linear moisture advection by flows from both the mean state and BSISO, while the middle-tropospheric center is induced by the nonlinear eddy moistening effect from the suppressed activity of synoptic tropical depression (TD) disturbances. The vertical profile of WPAC premoistening is significantly modulated by El Niño–Southern Oscillation (ENSO), with the premoistening being enhanced in the lower troposphere and weakened in the middle troposphere during an El Niño summer, and vice versa in a La Niña summer. During an El Niño summer, the nonlinear eddy moistening effect is weakened in the middle troposphere due to less southwest–northeast tilt of the TD, while the linear moisture advection is enhanced in the lower troposphere due to strengthened background cross-equatorial flows and moisture gradients. These results suggest an urgent need to improve the simulation fidelity of the BSISO’s scale interactions with synoptic and interannual variabilities in climate models.

Significance Statement

In this work, we use statistical analysis to explore multiscale interactions of BSISO with synoptic and interannual variabilities using observations and reanalysis data. Our key finding shows that the ENSO significantly modulates the premoistening process of the BSISO over the WPAC. In an El Niño summer, the WPAC nonlinear eddy moistening effect leading the BSISO is weakened in the midtroposphere due to smaller southwest–northeast tilt of the TD, while the linear moistening effect is enhanced in the lower troposphere due to enhanced background cross-equatorial flow and moisture gradient. These results offer new metrics for validating climate models and for projecting BSISO’s future change under different global warming scenarios.
Turbulent Mixing Variability in an Energetic Standing Meander of the Southern Ocean
Authors: Cyriac Ajitha , Phillips Helen E. , Bindoff Nathaniel L. , Polzin Kurt
Published: May 2022

This study presents novel observational estimates of turbulent dissipation and mixing in a standing meander between the Southeast Indian Ridge and the Macquarie Ridge in the Southern Ocean. By applying a finescale parameterization on the temperature, salinity, and velocity profiles collected from Electromagnetic Autonomous Profiling Explorer (EM-APEX) floats in the upper 1600 m, we estimated the intensity and spatial distribution of dissipation rate and diapycnal mixing along the float tracks and investigated the sources. The indirect estimates indicate strong spatial and temporal variability of turbulent mixing varying from O(10−6) to O(10−3) m2 s−1 in the upper 1600 m. Elevated turbulent mixing is mostly associated with the Subantarctic Front (SAF) and mesoscale eddies. In the upper 500 m, enhanced mixing is associated with downward-propagating wind-generated near-inertial waves as well as the interaction between cyclonic eddies and upward-propagating internal waves. In the study region, the local topography does not play a role in turbulent mixing in the upper part of the water column, which has similar values in profiles over rough and smooth topography. However, both remotely generated internal tides and lee waves could contribute to the upward-propagating energy. Our results point strongly to the generation of turbulent mixing through the interaction of internal waves and the intense mesoscale eddy field.

Published: May 2022

This study aimed to assess the relationship between the atherogenic index of plasma (AIP) and resting distal-to-aortic pressure ratio (Pd/Pa) in patients with intermediate coronary artery stenosis. This retrospective study included 802 chronic coronary syndrome patients with intermediate coronary artery stenosis who underwent fractional flow reserve (FFR) measurement. The resting Pd/Pa showed a significant negative correlation with AIP (rho= −.205, p < .001). When final FFR was divided into three tertiles (≤80, 81–89, ≥90), resting Pd/Pa was significantly lower, and AIP was markedly higher in the lower final FFR tertiles (both AIP and resting Pd/Pa differed significantly across the all three tertiles, p < .001). Furthermore, functionally significant stenosis independent predictors in multivariate analyses were AIP and resting Pd/Pa (p = .010 and p < .001, respectively). We observed for the first time an increase in AIP levels in the presence of functionally significant stenoses that may help better planning and identification of those patients with the functionally substantial atherosclerotic burden.
Auditory and Speech Outcomes of Cochlear Implantation in Children With Auditory Neuropathy Spectrum Disorder: A Systematic Review and Meta-Analysis
Authors: Bo Duan , Huang Yue , Wang Bing , Lu Ping , Chen Wen-xia , Xu Zheng-min
Published: May 2022

Objective:

The aim of this meta-analysis was to critically assess the effect of cochlear implantation on auditory and speech performance outcomes of children with auditory neuropathy spectrum disorder (ANSD).

Material and methods:

A systematic literature search was conducted on PubMed, EMbase, and Web of Science. The outcomes included speech recognition score, Categories of Auditory Performance (CAP), Speech Intelligibility Rating (SIR) score, and open-set speech perception. Results were expressed as standardized mean difference (SMD) or risk ratio (RR) with a 95% confidence interval (95% CI).

Results:

A total of 15 studies was included in this meta-analysis. Pooled data showed that, there were no significant differences between ANSD and sensorineural hearing loss (SNHL) groups in terms of speech recognition score (SMD = 0.01, 95% CI: −0.45, 0.47; P = .959),CAP (SMD = 0.71, 95% CI: −0.13, 1.54; P = .098), SIR score (SMD = −0.09, 95% CI: −0.49, 0.32; P = .667), and open-set speech perception (RR = 0.85, 95% CI: 0.69, 1.05; P = .142). Sensitivity analysis by removing individual studies one at a time showed that the overall estimate and level of heterogeneity did not change substantially.

Conclusion:

The current evidence suggested that children with ANSD who underwent cochlear implants achieved comparable effects in auditory and speech performance as children with non-ANSD SNHL.

Authors: Gupta Vrinda , Braverman Stephanie J. , Mai Johnny P. , Noller Michael , Camacho Macario , Tolisano Anthony M. , Zapanta Philip E.
Published: May 2022

Objectives:

Despite the growth of social media in healthcare, the appropriateness of online friendships between otolaryngological residents and attendings is poorly defined in the current literature. This issue is of growing importance, particularly as residency programs increasingly utilize social media as a means of connecting with and evaluating applicants due to limited in-person experiences during the COVID-19 pandemic. Our objective was to better understand the prevalence of and concerns surrounding social media use between residents and faculty.

Methods:

This study sent out 2 surveys in 2017 to all United States Otolaryngology residency program directors to disperse to their residents and attendings, respectively.

Results:

We received a response from 72 residents and 98 attendings. Our findings show that social media is commonly used by both residents and attendings, and most residents have at least 1 online friendship with an attending. Resident and attending opinions diverge on topics such as appropriateness of use, privacy settings, and professionalism.

Conclusions:

We call on residency programs to delineate a transparent social media policy so applicant expectations on social media are clear.
Sustainability of a Teacher Professional Development Program on Proportional Reasoning Skills of Students With Mathematics Difficulties
Authors: Jitendra Asha K. , Harwell Michael R. , Im Soo-hyun
Published: May 2022

Proportional reasoning is the cornerstone of many higher-level mathematics topics. We evaluated the sustainability effects of schema-based instruction (SBI) on proportional reasoning and the impact of professional development (PD) on the instructional practices of two cohorts of seventh-grade teachers (i.e., SBI-experienced-teacher implementers, who taught SBI in a previous study; SBI-novice-teacher implementers, who taught SBI for the first time with PD) and mathematics outcomes of students with mathematics learning difficulties. SBI was implemented for 6 weeks by 49 teachers in two distal states. Despite the cessation of PD provided to SBI experienced-teacher implementers, teachers in both cohorts demonstrated similar levels of fidelity. Results indicated no SBI experience effect on the immediate and 11-week retention tests of proportional problem solving, on a general measure of problem solving, and on an end-of-year mathematics achievement test, suggesting that the effectiveness of SBI generalizes over time to different cohorts of teachers and students.
Deep analysis of the transient behavior of centrifugal pumps during startup and shutdown
Authors: Zhang Yu-Liang , Ji Ying-Yu , Zhao Yan-Juan
Published: May 2022

The transient startup and shutdown of centrifugal pumps is inevitable and its transient performance has thus attracted increasing attention in recent years. This study aims to reveal the transient characteristics of centrifugal pumps during the start-stop process by using the dimensionless analysis method and quasi-steady-state method. The research objects are three typical centrifugal pumps with an impeller structure. The startup process includes quick and slow startup, and the shutdown process includes low-speed and high-speed idle rotation. Results show that the similarity law of centrifugal pumps can be applied to transient hydraulic performance prediction under full flow conditions during slow startup and under small flow conditions during quick startup and idle shutdown. Quick or slow startup does not affect the evolution of the dimensionless power coefficients. The research result may be useful for the design of the new fluidmachinery equipment by utilizing transient hydraulic performance.
Morphological and mechanical characterization of the Al-4032/granite powder composites
Authors: Kumar Deepak , Singh Pradeep K , Saini Pardeep
Published: May 2022

The main motive of this paper is to prepare a newer composite material using non-conventional reinforcement (industrial waste) for various industrial applications. The aluminium alloy (Al-4032) matrix based composites (AMCs) have been fabricated through bottom pouring stir casting method. The granite powder (GP, ceramic particles) obtained from waste (normally available from construction site) has been used as reinforcement, at 0, 3, 6, 9 % by weight. The particle size of the reinforcement has been up to 54μm. The morphological (microstructure, SEM, XRD) and mechanical (tensile strength, micro-hardness, impact strength) characterization of the AMCs have been carried out. The morphological study reveals that the reinforcement particles (GP) are almost uniformly distributed throughout the matrix phase. The mechanical properties of the AMCs have been observed to be better than the unreinforced alloy. It is expected that the fabricated Al-4032-GP composites will be useful for the automobile parts like piston, disc brakes, high speed machinery and high-speed rotating parts etc.
Restitution or Retribution? Detainee Payments and Insurgent Violence
Authors: Blair Christopher W.
Published: May 2022

Counterinsurgents frequently rely on mass arrests to impede rebel operations, but in so doing, risk detaining innocent civilians. Wrongful detention can backfire, fueling insurgent violence by alienating detainees and their kin. Can counterinsurgents mitigate wrongful detention through targeted compensation? I study this question using project-level data on US payments to individuals deemed innocent and released from Coalition custody in Iraq between 2004 and 2008. Leveraging plausibly exogenous variation in the allocation of detainee release payments, I document a robust, negative association between counterinsurgent compensation for wrongful detention and insurgent violence. The violence-reducing effects of detainee release payments were greatest in Sunni and mixed sectarian areas; for the types of insurgent attacks, most prone to civilian informing; and when detainee release was complemented by other population-centric reforms. These results suggest that post-harm mitigation helps shift civilian perceptions, inducing civilians to share more information with counterinsurgent forces.
Fields of Gold: Scraping Web Data for Marketing Insights
Authors: Boegershausen Johannes , Datta Hannes , Borah Abhishek , Stephen Andrew T.
Published: May 2022

Marketing scholars increasingly use web scraping and application programming interfaces (APIs) to collect data from the internet. Yet, despite the widespread use of such web data, the idiosyncratic and sometimes insidious challenges in its collection have received limited attention. How can researchers ensure that the data sets generated via web scraping and APIs are valid? While existing resources emphasize technical details of extracting web data, the authors propose a novel methodological framework focused on enhancing its validity. In particular, the framework highlights how addressing validity concerns requires the joint consideration of idiosyncratic technical and legal/ethical questions along the three stages of collecting web data: selecting data sources, designing the data collection, and extracting the data. The authors further review more than 300 articles using web data published in the top five marketing journals and offer a typology of how web data have advanced marketing thought. The article concludes with directions for future research to identify promising web data sources and embrace novel approaches for using web data to capture and describe evolving marketplace realities.

Published: May 2022

This systematic review aimed to summarize the evidence regarding death anxiety (DA) and related factors among nurses. Scopus, PubMed, Web of Science, Iranmedex, and Scientific Information Database (SID) databases were extensively searched using purpose-related keywords from the earliest to October 5, 2021. A total of 6819 nurses were included in 31 studies. The DA of nurses based on the Templer’s Death Anxiety Scale was moderate. Factors such as personal anxiety, frequency and severity of job stress, burnout, dying patient avoidance behavior, euthanasia, sex, mental health status, social desirability, attitude toward the elderly, humor, social maturity, psychological hardiness, quality of life, lack of social activity, self-efficacy, coping with death, and life satisfaction were associated with nurses’ DA. Therefore, nursing policymakers can promote nurses’ health to improve the quality of nursing care by considering these related factors.
Mortality Salience Effects of Critical Incidents – A Systematic Literature Review and Research Agenda
Authors: Leung Hoi-Ting , Chew Peter K. H. , Caltabiano Nerina J.
Published: May 2022

Critical incidents (CI) trigger acute stress reactions and psychological trauma because of direct or vicarious exposure. These events include natural disasters, wars, terrorist attacks and pandemics, and usually result in deaths and serious physical injuries. Their life-threatening nature makes them reasonable candidates to induce mortality salience (MS). The current review aims to consolidate Terror Management Theory (TMT) research using CIs as MS. A systematic literature review was conducted. Overall, 74 articles with 113 studies were included. Through this review, strong support for MS effects of CI has been found. Consistent with TMT, CIs tend to trigger worldview defence, self-esteem enhancement and relationship seeking. CIs have also been found to impact negatively on individual well-being and organisational health. Recommendations specific to crisis interventions and well-being will be discussed. The review concludes with potential future research directions to strengthen and expand empirical knowledge in CI salience.
How Do Voters Want to be Contacted and Are Parties Listening? Evidence from a Recent Election in Wales
Authors: Townsley Joshua , Cutts David
Published: May 2022

Content, messages and the way voters are contacted are all increasingly tailored to the individual. But are voters really contacted in the way they prefer? What actually drives campaign preferences? Who are parties tailoring these preferences to? For the first time, we address this gap in the literature. Our findings suggest that there is considerable heterogeneity in voters’ contact preferences. While some voters prefer not to be contacted, those who do prefer traditional methods (leaflets) and, in some cases, more personalised modes such as doorstep canvassing. Preferences are primarily driven by previous exposure to the mode, political interest, having an extraverted personality and age. We also examine preference ‘matching’ and find that parties are no more likely to ‘match’ a voter’s specific preference if they have contacted them before. Preference contact matching is significantly more likely to be targeted at women, middle-age voters and especially weak or nonpartisans.

Authors: Zhao Xin
Published: May 2022

Artificial intelligence (AI) technologies have contributed significantly to the advancement of society. In recent years, AI-powered writing assistants have received increasing attention among English as a Foreign Language (EFL) communities. However, most of these digital writing tools focus on the revision and editing stages. Few digital tools are developed to help users during the writing process, such as assisting users in formulating or translating their ideas into writing. Wordtune is an AI-powered writing assistant that understands the writer’s ideas and suggests options for rewriting them using different tones (e.g. casual, formal) and lengths (e.g. shorten, expand). This tool can help EFL writers maintain a continuous flow and learn useful ways to express their ideas in written English. This tech review aims to provide an overview of Wordtune and its affordance in English writing for EFL writers, while also addressing the benefits and limitations of this technology.
What is in a Name? The Politics of Name Changing
Authors: Kakati Bhaskar Kumar
Published: May 2022

Various socio-cultural and religious backgrounds influence the naming of an individual. For example, the Hindu belief system shapes the Assamese Hindu’s name in Assam. In contrast, the Islamic belief system shapes Assamese Muslim names, confirming that the personal name of an individual is a significant attribute of identification. It assists in identifying the individual. Equally, it also reveals the bearers’ socio-cultural and religious backgrounds. Therefore, the name directly or indirectly can affect the personal and social life of the individual. As the name can affect the individual’s life, sometimes an individual has to change their name to enjoy social, cultural and political benefits. This article carefully analyses how the name affects the name bearer and why an individual may seek to change his/her name.

In our technology-based society, individuals have more tools that they can use to manage and ‘show’ themselves in public space. In public space, they are monitored by agencies using surveillance practices but they also share information through location-aware technologies. This profound condition alters social norms and, with that, not only change self-rituals practiced in public but also group gatherings in public spaces. With an emphasis on political protests, this commentary focuses on a set of related questions: what characterises contemporary self-rituals in public space? How are these rituals being altered by digitisation processes? How are these changes manifested in the performance of the self during protests? This commentary suggests that public protests in the digital age are ‘moments of togetherness’, accelerated by social media, which dramatically enhance personalisation processes in collective actions. Reflecting on the contemporary alteration of group rituals and protests as extensions of the self, the commentary ends with a discussion about the opportunities and challenges this might bring for future collective actions.
New institutions and the politics of the interstices. Experimenting with a face-to-face democracy in Naples
Authors: Pinto Mauro , Recano Luca , Rossi Ugo
Published: May 2022

This article analyses the politics of new municipalism in Naples in relation to the constellation of ‘new institutions’ that has arisen from this politics. These ‘new institutions’ are illustrative of a politics of the interstices as a distinctive trait of the convergence between city government and social movements in Naples, as the latter have opted for staying neither outside nor inside official institutions and the city government has adapted its conduct to this strategy. To illustrate this point, the article explores the emerging constellation of ‘new institutions’ in Naples, which is understood as an embryonic form of radical ‘face-to-face democracy’ (in Murray Bookchin’s terms) at the municipal level, that departs from mainstream conceptions of participatory democracy and commons-based democracy. Through this analysis, the article argues that the experience of new municipalism in Naples offers evidence of a kind of participatory urban democracy understood not in a procedural sense but in a genuinely political vein, where civic participation and political conflict productively coexist with institutional creativity.

With the continuous development of pipeline transportation industry, pipeline leakage often occurs, posing a great threat to people’s lives and property safety. In order to improve the detection accuracy of natural gas pipeline leakage, a pipeline leakage detection method based on improved variational mode decomposition algorithm and Lempel–Ziv complexity analysis is proposed. In this work, the normalized mutual information is used to determine the decomposition level K of variational mode decomposition, and the Lempel–Ziv complexity analysis algorithm is used to extract pipeline signal feature. The results show that the proposed leakage detection method has higher classification accuracy than other methods, which verifies the effectiveness of this method in the process of pipeline leakage detection.
Internationalizing public administration education: Why and how?
Authors: White Allison C
Published: May 2022

Public administration educators in the United States have renewed their interest in incorporating an international perspective into their teaching. Why is this perspective important for students and how can educators integrate it meaningfully? In this article, I provide an argument for the internationalization of public administration curricula, generate nine “principles of practice” to help guide internationalization efforts, and specify two broad strategies through which an international dimension can be integrated into public administration curricula—one for leveraging comparative material in domestically-focused curricula and another for developing a distinct and standalone internationally-focused specialization.

Published: May 2022

Objectives

This study aimed to investigate the audiological outcomes and subjective benefits of transcutaneous bone conduction implants (BCIs) in patients with single-sided deafness (SSD).

Methods

This retrospective study was conducted on 11 patients with SSD implantations between 2015 and 2018 at a tertiary center. Pure-tone audiometry, speech reception threshold (SRT), and speech-in-noise (SPIN) tests were performed. Preoperative and postoperative performances were compared. Subjective satisfaction level was assessed using validated questionnaires. A PubMed search was conducted to identify the relevant studies published to date.

Results

All patients demonstrated significant audiological improvements compared with their preoperative condition. The mean SRT improved significantly ( p = 0.001) from 109 dB to 23 dB after implantation. The mean SPIN score improved significantly after implantation. The questionnaires showed an overall positive benefit of transcutaneous bone conduction devices (BCDs). A literature search revealed 21 articles, of which 14 reported the use of BCIs in patients with SSD. Our results agree with the published evidence showing the overall benefit of BCI in patients with SSD.

Conclusions

Transcutaneous BCDs could be considered as an alternative treatment option for patients with SSD, it could show good audiological outcomes and high satisfaction levels. Further studies should be conducted on patients with SSD to determine the most appropriate hearing solutions.
Laughing to forget or to remember? Anne Frank memes and mediatization of Holocaust memory
Authors: González-Aguilar Juan Manuel , Makhortykh Mykola
Published: May 2022

The rise of user-generated content (UGC), such as internet memes and amateur videos, enables new possibilities for mediatization of the past. However, these possibilities can facilitate not only more diverse and less top-down engagements with memory, but also lead to its trivialization and distortion of historical facts. The latter concerns are particularly pronounced in the case of memories about mass atrocities (e.g. the Holocaust), where online media are often used to promote denialism and attack the victims’ dignity. To better understand the relationship between UGC and memory mediatization, we examine a selection of internet memes dealing with Anne Frank, an iconic Holocaust victim. Using a combination of inductive content analysis and close reading, we identify four classes of Anne Frank memes: (1) ad hominems; (2) deniers; (3) trivializers; and (4) thought provokers. Our findings demonstrate the multi-faceted functionality of memes, which are used not only to trivialize Holocaust memory, but also to reinforce canonical narratives about Anne Frank, and highlight the dependency of memes on other forms of memory mediatization, thus raising questions about the interrelations between UGC and institutionalized forms of remembrance.
The role of exteroceptive and interoceptive awareness in executing socially relevant bodily actions: A naturalistic investigation of greeting behaviour in the UK and Spain
Authors: Payne-Allen Kieran J , Pfeifer Gaby
Published: May 2022

Body awareness is tightly linked to motor action. Non-verbal greetings constitute a behaviour through which an awareness of both socio-cultural habits (exteroceptive awareness) and internal bodily states (interoceptive awareness) play out to influence the structure of action. To establish the effect of culture on non-verbal greeting behaviours, naturalistic observations were carried out in two countries (Britain and Spain) that are purported to exhibit differences in greeting types. Interoceptive awareness (IA) was subsequently measured in a proportion of observed participants ( N = 33) who filled in the Multidimensional Assessment of Interoceptive Awareness, Version 2 (MAIA-2). As expected, a significant difference in greeting type was observed between British ( N = 252) and Spanish ( N = 244) greeters. Scores of greeting intimacy and competency did not differ significantly between Britain and Spain. However, independent of culture, several moderate and strong relationships emerged between selective dimensions of the MAIA-2 and scores of intimacy and competency. Specifically, intimacy and competency scores were positively correlated with the ‘Awareness of Mind-Body Integration’ dimension. Greeting intimacy yielded additional positive relationships with the Not Distracting and Trusting subscales, and a negative relationship with the Not Worrying subscale. These relationships suggest that IA facilitates healthy social approach behaviour as expressed through greetings, irrespective of cultural greeting differences. We discuss IA and greeting behaviour in the context of attachment, consider the clinical implications for social anxiety and the future implications for social interactions in a post-COVID-19 era.
Modifying priming techniques in cardiopulmonary bypass circuit in known case of sickle-cell trait undergoing open heart surgery

Modifying cardiopulmonary bypass (CPB) circuit’s priming technique before the onset of CPB in cardiac patients known with sickle-cell disease or sickle cell trait has been observed to be of substantial significance in dealing with such challenges without having any life-threatening consequences. We modified our routine heparinized crystalloid priming of the CPB circuit with partial exchange transfusion by adding donor blood (packed red blood cells), fresh frozen plasma (FFP), and bicarbonate. This has helped us bring down the overall sickle cell hemoglobin in the blood thereby reducing its risk of sickling.
Effectiveness of vortioxetine in patients with major depressive disorder comorbid with generalized anxiety disorder: Results of the RECONNECT study
Authors: Christensen Michael Cronquist , Schmidt Simon , Grande Iria
Published: May 2022

Background:

Major depressive disorder (MDD) and generalized anxiety disorder (GAD) are frequently comorbid.

Aims:

To assess the effectiveness of vortioxetine in patients with MDD and comorbid GAD.

Methods:

Open-label, 8-week study (NCT04220996) in 100 adult outpatients with severe MDD and severe comorbid GAD receiving vortioxetine as first treatment for the current depressive episode or switching to vortioxetine due to inadequate response to another drug for depression. Vortioxetine starting dosage was 10 mg/day, with forced up-titration to 20 mg/day after 1 week. Response was defined as ⩾50% decrease in Montgomery–Åsberg Depression Rating Scale (MADRS) and/or Hamilton Anxiety Rating Scale (HAM-A) total score from baseline; remission defined as MADRS and/or HAM-A total score ⩽10.

Results:

Clinically meaningful and statistically significant improvements from baseline in symptoms of depression and anxiety, and overall functioning and health-related quality of life, were observed after 8 weeks’ vortioxetine treatment (all changes p < 0.0001 vs baseline). At week 8, rates of MADRS response and remission were 61% and 35%, respectively. Corresponding rates of HAM-A response and remission were 55% and 42%. Response on both the MADRS and HAM-A scales was achieved by 52% of patients; 31% achieved remission on both scales. Vortioxetine dose up-titration was well tolerated; no unexpected adverse events were reported.

Conclusion:

Vortioxetine demonstrates effectiveness in significantly reducing symptoms of both depression and anxiety in patients with severe MDD comorbid with severe GAD. Findings support increasing vortioxetine dosage to 20 mg/day early in the course of therapy, and show that this may be achieved without compromising tolerability.

Published: May 2022

The technological scenarios that have arisen in Latin American universities have been substantially changing in recent months as a result of the international health emergency caused by COVID-19. The lockdown policy revealed the need to develop digital and informational skills to adapt to the environment and the demands of distance learning required for integral online education. In order to observe and systematize the transformation of the technological environment in academic libraries during these months, the recent situation was identified based on data analysis obtained from a questionnaire applied in Latin American countries. The results reported significant changes in the use of digital applications, services, user assistance and librarian training during the pandemic, as well as the libraries’ mid-term commitments.
