Cultural Destruction and Mass Atrocity Crimes: Strengthening Protection of Intangible Cultural Heritage
Authors: Paauwe Juliette , Pittalwala Jahaan
Published: August 2021

Attacks against or affecting cultural heritage have been prosecuted exclusively as war crimes at both the International Criminal Tribunal for the former Yugoslavia and the International Criminal Court. However, this jurisprudence has limited the very concept of cultural heritage to solely tangible or physical manifestations of culture, excluding the numerous intangible cultural expressions of a given collective. This has precluded a constitutive link between attacks on cultural elements and crimes against humanity and genocide, and ignored the myriad ways in which the destruction of cultural heritage can adversely affect protected groups, including the disintegration of their collective identity. The rights of minority and indigenous populations such as the Uighurs in China can be better protected if acts damaging culture, including intangible cultural heritage, are inherently linked to crimes against humanity and genocide as this will compel states to better acknowledge, address, and prevent these crimes, in line with their obligations under the Responsibility to Protect.
Class Struggle from Above and from Below during the covid-19 Pandemic
Authors: Azzellini Dario
Published: August 2021

Crises under capitalism, as historical analysis proves, tend to entail a transfer of wealth from the poor to the wealthy. Inequalities between poor and wealthy, between people of color and white people, between North and South and between genders are increasing. Most scholars will agree that this is also happening on a global level as a consequence of the handling of the covid-19 pandemic. However, there is a lot of disagreement regarding the evaluation of workers’ resistance. Some observe a global increase in workers’ struggles since the pandemic took hold in March 2020, some deny it, and others, maybe most, pay little attention to workers’ struggles. The differing points of view also go back to diverging positions on the importance of class, labor and workers’ organization. This article outlines the dimensions of the class war from above, provides an initial overview and systematization of the workers’ struggles, discusses the transformative power of workers’ struggles and presents a preliminary evaluation.
Impact of the Lack of Diversity Within Surgery Career Pathways and Mitigating Factors
Authors: Sutton Erica , Montgomery Rice Valerie
Published: August 2021

The lack of diversity in surgical career pathways impacts the cultural competence of the learning and working environment, the variety of leadership styles found within surgical leadership, and the ability of an organization to achieve equity in the workplace due to ongoing mistrust and untouched bias. Leading mitigating factors include developing pathways for greater numbers of diverse people at the high school and college level and implicit bias training. Though educators have had some success with these factors in the initial stages of diversifying early pathways, these factors are not yet correlated to entry into a surgical career. Future solutions to the lack of diversity in surgery will be predicated on surgeons collectively valuing justice, equity, diversity, and inclusion.
Pulmonary Embolism and Sigmoid Sinus Thrombosis After Translabyrinthine Vestibular Schwannoma Resection: A Retrospective Case Series
Authors: Song Yohan , Ayoub Noel , Chen Jenny X. , Alyono Jennifer C. , Welling D. Bradley
Published: August 2021

Objective:

To describe the presentation and treatment of patients developing pulmonary embolism following translabyrinthine approach for vestibular schwannoma resection.

Methods:

This was a retrospective case series of patients at 2 academic tertiary medical centers who developed symptomatic pulmonary embolism post-operatively following translabyrinthine approach for vestibular schwannoma resection and were found to have evidence of sigmoid sinus thrombosis.

Results:

Three patients were identified to have post-operative pulmonary emboli after translabyrinthine approach for vestibular schwannoma resection with sigmoid sinus or internal jugular vein clots in the absence of lower extremity deep vein thrombosis. Caprini scores for these patients were 5 or lower. All patients underwent CT pulmonary angiography and were confirmed to have pulmonary emboli. Two were promptly anticoagulated with heparin drips and transitioned to long-term oral anticoagulation therapy and 1 had delayed anticoagulation. None of these patients suffered from intracranial hemorrhage post-operatively.

Conclusions:

Patients undergoing translabyrinthine approach for vestibular schwannoma can develop pulmonary embolism from sigmoid sinus entry or thrombosis. No clear guidelines exist for the management of this complication in the setting of recent craniotomy and the risk of intracranial hemorrhage must be considered prior to initiating anticoagulation.
Vascular Loops: The Innocent Bystander for Vestibular Paroxysmia
Authors: Teh Carren Sui-Lin , Noordiana Siti Hajar , Shamini Shanmugalingam , Prepageran Narayanan
Published: August 2021

Introduction:

Vestibular paroxysmia (VP) is a condition with recurrent short bouts of vertigo and is thought to be part of a neurovascular compression syndrome caused by the vascular loop. However, this is still being debated as vascular loops are considered as normal variants with limited studies involving vertiginous patients.

Objectives:

The aim of this paper is to study the association between audiovestibular symptoms and the presence of vascular loops and to study the association between vestibular paroxysmia and vascular loops.

Design:

This is a retrospective analysis of clinical, audiological and MRI findings of patients with and without vascular loops and vestibular paroxysmia from 2000 to 2020.

Results:

A total of 470 MRI Internal Auditory Meatus scans were performed during the study period of which, 71 (15.1%) had vascular loops and 162 (34.5%) had normal MRI which were used as controls. From the 233 subjects recruited, there were 37 subjects with VP and 196 non VP subjects were used as controls. There was no association between the vascular loop and control groups in terms of co-morbidity and audiovestibular symptoms. The VP group had a significantly older mean age of 51.8 (SD ± 10.3) as compared to the non VP group with the mean age of 45.6 (SD ± 15.5). The VP group had higher number of patients presenting with hearing loss at 97.3% when compared with those without VP (80.1%) ( P = .01). The odds of having a vascular loop giving rise to VP was not statistically significant at 0.82 (95% CI 0.3735-1.7989) P = .62.

Conclusion:

The vascular loop is a normal variant which may or may not give rise to audiovestibular symptoms or vestibular paroxysmia. Clinical assessment is still most important tool in deriving a diagnosis of VP and MRI may be useful to rule out other central causes.

Published: August 2021

Raman spectroscopy is a non-invasive optical technique that can be used to investigate biochemical information embedded in cells and tissues exposed to ionizing radiation used in cancer therapy. Raman spectroscopy could potentially be incorporated in personalized radiation treatment design as a tool to monitor radiation response in at the metabolic level. However, tracking biochemical dynamics remains challenging for Raman spectroscopy. Here we developed a novel analytical framework by combining group and basis restricted non-negative matrix factorization and random forest (GBR-NMF-RF). This framework can monitor radiation response profiles in different molecular histotypes and biochemical dynamics in irradiated breast cancer cells. Five subtypes of; human breast cancer (MCF-7, BT-474, MDA-MB-230, and SK-BR-3) and normal cells derived from human breast tissue (MCF10A) which had been exposed to ionizing radiation were tested in this framework. Reference Raman spectra of 20 biochemicals were collected and used as the constrained Raman biomarkers in the GBR-NMF-RF framework. We obtained scores for individual biochemicals corresponding to the contribution of each Raman reference spectrum to each spectrum obtained from the five cell types. A random forest classifier was then fitted to the chemical scores for performing molecular histotype classifications (HER2, PR, ER, Ki67, and cancer versus non-cancer) and assessing the importance of the Raman biochemical basis spectra for each classification test. Overall, the GBR-NMF-RF framework yields classification results with high accuracy (>97%), high sensitivity (>97%), and high specificity (>97%). Variable importance calculated in the random forest model indicated high contributions from glycogen and lipids (cholesterol, phosphatidylserine, and stearic acid) in molecular histotype classifications.
Assessing the Financial Implications of COVID-19 Within the SVAR Framework for Some Asian Countries
Authors: Narayan Seema , Purnaningrum Evita , Khawari Baqir
Published: August 2021

This article examines the structural responses of foreign exchange and equity markets to the COVID-19 pandemic in seven Asian countries over its first 4 months (31 December 2019 to 1 May 2020). Marginal effects derived from a structural vector autoregression (SVAR) model suggest that a 1% increase in incidence of COVID-19 cases significantly diminished Indonesia’s equity market returns by 4.7%, depreciated the Indian rupee against the US dollar by 4.8%, but improved equity prospects in South Korea by 4.1%. For the other financial markets, the effect of COVID-19 was found to be insignificant. Further, the impulse response analyses imply that the influence of COVID-19 on foreign exchange and equity markets is only transitory in nature. Additional SVAR analysis for India and Indonesia over recent months (2 May 2020 to 22 January 2021) showed that their financial markets remained (or became) resistant to the escalating incidence of COVID-19 inflections and deaths.

Diversions: How the Underrepresentation of Research on Advantaged Groups Leaves Explanations for Health Inequalities Incomplete
Authors: Link Bruce G. , García San Juanita
Published: August 2021

We identify a gap in health inequalities research that sociologists are particularly well situated to fill—an underrepresentation of research on the role advantaged groups play in creating inequalities. We name the process that creates the imbalance health-inequality diversions. We gathered evidence from awarded grants (349), major health-related data sets (7), research articles (324), and Healthy People policy recommendations. We assess whether the inequality-generating actions of advantaged groups are considered either directly by capturing their behaviors or indirectly by asking disadvantaged people about discrimination or exploitation from advantaged groups. We further assess whether there is a tendency to locate the problem in the person or group experiencing health inequalities. We find that diversions are prevalent across all steps of the research process. The diversion concept suggests new lines of sociological research to understand why diversions occur and how gaps in evidence concerning the role of the advantaged might be filled.
Integrated neural network model with pre-RBF kernels
Authors: Wen Hui , Yan Tao , Liu Zhiqiang , Chen Deli
Published: August 2021

To improve the network performance of radial basis function (RBF) and back-propagation (BP) networks on complex nonlinear problems, an integrated neural network model with pre-RBF kernels is proposed. The proposed method is based on the framework of a single optimized BP network and an RBF network. By integrating and connecting the RBF kernel mapping layer and BP neural network, the local features of a sample set can be effectively extracted to improve separability; subsequently, the connected BP network can be used to perform learning and classification in the kernel space. Experiments on an artificial dataset and three benchmark datasets show that the proposed model combines the advantages of RBF and BP networks, as well as improves the performances of the two networks. Finally, the effectiveness of the proposed method is verified.
Dynamic characteristics analysis of planetary gear system with internal and external excitation under turbulent wind load

Published: August 2021

According to the working characteristics of a 1.5 MW wind turbine planetary gear system under complex and random wind load, a two-parameter Weibull distribution model is used to describe the distribution of random wind speed, and the time-varying load caused by random wind speed is obtained. The nonlinear dynamic model of planetary gear transmission system is established by using the lumped parameter method, and the relative relations among various components are derived by using Lagrange method. Then, the relative relationship between the components is solved by Runge Kutta method. Considering the influence of random load and stiffness ratio on the planetary gear transmission system, the nonlinear dynamic response of cyclic load and random wind load on the transmission system is analyzed. The analysis results show that the variation of the stiffness ratio makes the planetary gear have abundant nonlinear dynamics behavior and the planetary gear can get rid of chaos and enter into stable periodic motion by changing the stiffness ratio properly on the premise of ensuring transmission efficiency. For the variable pitch wind turbine, the random change of external load increases the instability of the system.
Muddying the waters: migration management in the global commons
Authors: Lori Noora , Schilde Kaija
Published: August 2021

Advanced liberal democratic states interdict migrants on the High Seas global commons. Why have liberal states engaged in this practice over the past four decades? Deterrence and humanitarian rescue explain part of this puzzle, but they are insufficient for understanding the patterns and justifications for migrant interdiction on the High Seas. Tension between states promoting international human rights and circumventing those obligations challenges expectations of liberal state behavior. International relations scholars must incorporate the global commons when explaining state behavior; ungoverned areas create exceptional zones for states to partially suspend their standard operating procedures to execute policies furthering their interests. We argue that liberal states use the regulatory gray zones of the High Seas to ‘muddy the waters’ in order to advance their security interests. States with the highest domestic refugee protections have incentives to circumvent their own obligations, which vary over time with changes to domestic asylum laws.
Examination of the Moderating Role of Household Income in the Association Between Cognitive Social Capital and Subjective Well-Being Among Rural Older Adults in Northeast China
Authors: Zhang Jingyue , Tian Yipeng , Lu Nan
Published: August 2021

The present study explored the moderating effects of household income on the relationship between cognitive social capital and subjective well-being in rural community-dwelling older adults in China. The data were derived from a rural community survey conducted in Liaoyuan City in China’s Jilin Province in 2019. The analytic model featured 458 respondents who completed the survey. We used multiple group analyses to test the hypotheses. A latent construct of cognitive social capital was built using social trust and reciprocity indicators. The results showed that household income had a significant moderating effect on the association between cognitive social capital and life satisfaction, but not on the relationship between cognitive social capital and depressive symptoms. Thus, household income and cognitive social capital should be used to assess subjective well-being in older populations. Older adults with low household income deserve particular attention in the design of future social capital policies and programs.
What the controversy over ‘the reasonable’ reveals: On Habermas’s Auch eine Geschichte der Philosophie
Authors: Ferrara Alessandro
Published: August 2021

This article discusses Jürgen Habermas’s latest book Auch eine Geschichte der Philosophie from the specific angle of what the section on Rawls indicates about the overall philosophical project pursued by Habermas. This tiny element within the imposing architecture reveals a structural problem that affects Habermas’s program for a detranscendentalization of reason. After a general premise, Habermas’s appraisal of Rawls’s work is reconstructed and critically examined (Section 1). Then, in the guise of a Rawlsian rejoinder, a problematic understanding of pluralism is shown to undergird Habermas’s overlooking of the ground-breaking potential of the normativity of ‘the reasonable’ and ‘the most reasonable’ (Section 2). Finally, this neglect is argued to be indicative of a deeper lacuna: namely, a missing confrontation with Wittgenstein’s rival path to a postmetaphysical, intersubjective, detranscentendalized reason (Section 3). That lacuna, finally, invites a closer scrutiny of the overall genealogical picture and its central opposition between two pathways (related to Kant and Hume) to the postmetaphysicization of reason.

Published: August 2021

Suicide represents a public health issue that requires new preventive strategies. Therefore, this study analyzes differences in language use between a themed posts group (suicide and depression) and a random posts group (non-specific topics) from different social media platforms. In addition, the similarity of the texts of themed posts group with the set of phrases linked to suicide risk factors is analyzed. Texts were processed using the Linguistic Inquiry and Word Count (LIWC) software. A 95% bootstrap confidence interval (CI) was built for the difference in means for the resulting values per word category across groups. Significant differences in the use of language were observed between the themed post group and the random post group, whereas no differences were found between the themed post group and the set of phrases linked to suicide risk factors. These results can contribute to the development of risk-detection tools, which identify users at risk based on the analysis of language use embedded in social media. Such opportune detection would significantly increase the suicide prevention work. However, there is still a latent need for doing more research in this field, especially for the Mexican culture.
Exploring how couples navigate the COVID-19 pandemic using Wefulness Theory
Authors: Nuru Audra K. , Bruess Carol J.
Published: August 2021

Framed by Wefulness Theory (WT; Nuru & Bruess, 2022), the present study explores the COVID-19 global pandemic as a context for examining relational struggle and strength during times of challenge. Analysis of in-depth, dyadic interviews with 54 couples who reflect a broad range of ethnic-racial compositions, partnership structures, sexual orientations, and ages rendered intelligible relational partners’ wefulness practices in situ. Results reveal four suprathemes: (a) cultivating relational consciousness, (b) negotiating wefulness amidst challenge, (c) accepting life on life’s terms, and (d) inviting challenge as opportunity for growth. Data reveal how relational partners engage in ritualized (re)commitments as multi-vocal practices of expressing and embracing the current pandemic moment. Data also evidenced WT is heuristically powerful in reconceptualizing and illuminating relational meaning- and sense-making.
Cable manipulation with a tactile-reactive gripper
Authors: She Yu , Wang Shaoxiong , Dong Siyuan , Sunil Neha , Rodriguez Alberto , Adelson Edward
Published: August 2021

Cables are complex, high-dimensional, and dynamic objects. Standard approaches to manipulate them often rely on conservative strategies that involve long series of very slow and incremental deformations, or various mechanical fixtures such as clamps, pins, or rings. We are interested in manipulating freely moving cables, in real time, with a pair of robotic grippers, and with no added mechanical constraints. The main contribution of this paper is a perception and control framework that moves in that direction, and uses real-time tactile feedback to accomplish the task of following a dangling cable. The approach relies on a vision-based tactile sensor, GelSight, that estimates the pose of the cable in the grip, and the friction forces during cable sliding. We achieve the behavior by combining two tactile-based controllers: (1) cable grip controller, where a PD controller combined with a leaky integrator regulates the gripping force to maintain the frictional sliding forces close to a suitable value; and (2) cable pose controller, where an linear–quadratic regulator controller based on a learned linear model of the cable sliding dynamics keeps the cable centered and aligned on the fingertips to prevent the cable from falling from the grip. This behavior is possible with the use of reactive gripper fitted with GelSight-based high-resolution tactile sensors. The robot can follow 1 m of cable in random configurations within two to three hand regrasps, adapting to cables of different materials and thicknesses. We demonstrate a robot grasping a headphone cable, sliding the fingers to the jack connector, and inserting it. To the best of the authors’ knowledge, this is the first implementation of real-time cable following without the aid of mechanical fixtures.

Impact of COVID-19 on Waiting Passenger Distribution on a Bus Rapid Transit Station Platform in Brisbane, Australia
Authors: Jayatilake Sewmini , Bunker Jonathan M.
Published: August 2021

The operation of a bus rapid transit (BRT) station platform is a key factor that affects BRT system performance. As waiting passengers occupy more platform space than circulating passengers, evaluation of their distribution across the platform is important. Public transport systems have been affected by the global pandemic Coronavirus disease 2019 (COVID-19). This may have affected the waiting passenger distribution on BRT platform space. Therefore, this study aimed to identify the impact of COVID-19 on waiting passenger distribution on a platform during the peak period at an important station on the BRT system in Brisbane, Australia. Manual data collection was carried out before COVID-19 and during COVID-19. Waiting passenger counts in each case were evaluated separately to identify variation across the platform. The total waiting passenger count on the platform at a given time reduced significantly during COVID-19. To compare the two cases, data sets were normalized, and statistical analysis performed. The test results indicated that the distribution of waiting passengers during COVID-19 has significantly changed, bringing more waiting passengers into the platform center than the two ends, whereas before COVID-19, more waiting passengers were observed at the upstream half of the platform. There was also greater temporal variation across the whole platform during COVID-19. These findings were used to postulate the reasons behind the changes resulting from COVID-19, which affected platform operation.
Driving Coverage of Charging Stations for Battery Electric Trucks Located at Truck Stop Facilities
Authors: Hurtado-Beltran Antonio , Rilett Laurence R. , Nam Yunwoo
Published: August 2021

Battery-powered electric trucks could soon be deployed on a large scale along long-haul routes on the U.S. trunk highway system. These vehicles have numerous advantages, including zero emissions, fuel savings, and lower maintenance costs, that make them attractive for motor carrier companies. However, the deployment of this technology depends on the development of a convenient network of fast-charging stations that can provide sufficient driving coverage along the Interstate highway system. The majority of existing fast-charging stations in rural areas currently are not adequate for the movement of large trucks. A potential solution is to install fast-charging stations at the vast network of rural truck stops. Truck stops are specifically designed for the movement of trucks and are already located on the routes with the highest truck demand. The main objective of this study was to develop a methodology for identifying the driving coverage provided if fast-charging stations were located at truck stop facilities along the U.S. Interstate highway system. The contiguous U.S.A. was taken as the study area. The study approach was based on a geographic information system network analysis with a specific focus on the service area. It was found that truck stop facilities could potentially provide 99.5% driving coverage for electric trucks on the Interstate highway system. This makes them opportune locations for future fast-charging stations. These findings may assist transportation planners and operators in defining strategies required for planning the deployment of long-haul electric trucks on the U.S. highway system.
Development, Crash Testing, and Evaluation of Steel-Post Trailing-End Guardrail Anchorage System
Authors: Asadollahi Pajouh Mojdeh , Lechtenberg Karla , Faller Ronald , Yosef Tewodros
Published: August 2021

Trailing-end guardrail anchorage systems are widely used by most state departments of transportation (DOTs) and generally consist of simple adaptations of crashworthy end terminals. The safety performance and structural capacity of these trailing-end anchorage systems, when reverse-direction impacts occur near the end, is imperative in crashworthiness of guardrail systems. In 2013, a non-proprietary trailing-end anchorage system with a modified breakaway cable terminal (BCT) was developed by the Midwest Roadside Safety Facility (MwRSF) for the Midwest Guardrail System (MGS). Although this trailing-end guardrail anchorage system adequately met the Manual for Assessing Safety Hardware (MASH) TL-3 safety requirements, the use of two breakaway wood posts was deemed by some users to have several drawbacks. Thus, there was a critical need to develop a non-wood option to anchor the downstream end of the W-beam guardrail system, which led to the need to develop a steel-post trailing-end guardrail anchorage system for use with the MGS. Following the design and component testing of such a system, two full-scale crash tests were performed according to the MASH 2016 test designation nos. 3-37a and 3-37b. In the first test, a 2270P pickup truck struck the guardrail system and was adequately contained and redirected. In the second test, an 1100C small car struck the barrier and safely gated through the barrier. Both tests were deemed acceptable according to TL-3 safety criteria in MASH 2016. Recommendations are provided for the installation of a steel-post trailing-end guardrail anchorage system when used in combination with MGS.
Outcomes of Surgically Treated Fifth Metatarsal Fractures in Major League Soccer Athletes
Authors: Stone Jonathan A. , Miranda Alejandro D. , Gerhardt Michael B. , Mandelbaum Bert R. , Giza Eric
Published: August 2021

Background:

Sports-related fractures of the fifth metatarsal are common in professional athletes. Data regarding outcomes of surgical management including refracture, complications, and return-to-play statistics are available for other professional American sports with a notable exception of soccer.

Purpose:

To quantify the burden of operative fifth metatarsal fractures in Major League Soccer (MLS) athletes, to compare outcomes as well as refracture and complication rates with other professional sports, to analyze factors that may contribute to treatment failure, and to report on return-to-play characteristics for affected players.

Study Design:

Case series; Level of evidence, 4.

Methods:

We searched all injuries in the prospectively collected HealtheAthlete database for MLS for operative fifth metatarsal fractures for seasons 2013 to 2017. Additional information regarding each fracture including demographics, treatment, postoperative course, and return-to-play statistics were compiled from HealtheAthlete and supplemented by teams’ chief medical officers, coaches, trainers, and online sources.

Results:

There were 21 fractures in 18 players during the study period. Mean time to radiographic healing was 8.5 weeks (n = 17). Mean time to return to play was 11.1 weeks (n = 19). Of 21 fractures, 20 (95%) players returned to sport. Of 18 players, 4 (22.2%) experienced refracture. Of 18 players, 5 (27.8%) and 2 (11.1%) reported previous stress injuries on the contralateral and ipsilateral limb, respectively. Player performance characteristics showed small declines in the first year of return that improved by the second year.

Conclusion:

MLS athletes who sustain a sports-related fifth metatarsal fracture can expect a high rate of return to sport with time to radiographic healing and return to play as well as risk of refracture similar to other professional cohorts.
Evaluation of potential toxicity of Steriplant©N aerosolization toward human alveolar cells A459 in vitro

Published: August 2021

Protection of patients against hospital-acquired infections is of major importance. Disinfection of magnetic resonance imaging suites is, due to their unique properties and environment particularly, difficult to implement. We developed an OPTI-JET CS MD 2ZE aerosolizator for disinfection of a magnetic resonance imaging suite using the electrolyzed oxidizing water biocide Steriplant©N. The disinfection of the magnetic resonance imaging suite with this system reduced from the number of colony formed unit/m3 air by 87% and 96% in 6 and 15 min of disinfection, respectively. It is well known that exposure of personnel or patients to aerosols may represent risk to the respiratory system; therefore, the aim of this study was to assess potential cytotoxicity and genotoxicity of Steriplant©N aerosolization toward human alveolar cells A459 in vitro . The A459 cells were exposed to aerosol containing different concentrations (50% and 100% v/v) of Steripalnt©N for 6 min in a chamber that had been constructed to simulate the conditions in the magnetic resonance imaging suite. The cytotoxicity was evaluated by measuring iodide uptake, and the genotoxicity was determined by measuring formation of phosphorylated H2AX histones, a marker for deoxyribonucleic acid double-strand breaks, immediately after the aerosolization and after 1, 4, and 24 h postincubation. The results demonstrated that aerosolization with Steriplant©N at conditions reflecting aerosolization in a magnetic resonance imaging suite is not cytotoxic and does not exhibit genotoxic potential in vitro.
Thermoelastic stability of thin CNT-reinforced composite cylindrical panels with elastically restrained edges under nonuniform in-plane temperature distribution
Authors: Trang Le Thi Nhu , Van Tung Hoang
Published: August 2021

In order to fill the evident lack of investigations on nonlinear response of nanocomposite curved panels under nonuniform temperature, this paper aims to analyze the nonlinear thermoelastic stability of cylindrical panels made of carbon nanotube (CNT) reinforced composite, rested on elastic foundations and subjected to sinusoidal-type in-plane temperature distribution. Reinforcement is carried out through functional rules of CNT volume fraction. An extended rule of mixture is adopted to estimate the effective properties of CNT-reinforced composite. Governing equations are derived based on classical shell theory accounting for von Kármán–Donnell nonlinearity, initial imperfection, interactive pressure from elastic foundation, and preexisting lateral pressure. In addition, the elasticity of in-plane constraints of boundary edges is included. Approximate analytical solutions are assumed to satisfy simply supported boundary conditions and Galerkin procedure is adopted to derive nonlinear closed-form relation between thermal load and deflection. Parametric studies are carried out and interesting remarks are obtained. The present study finds that, unlike case of uniform temperature rise, thermal instability of cylindrical panels under sinusoidal temperature distribution still occurs even though all edges are movable and load carrying capacity is the weakest for an intermediate value of CNT volume fraction. Under sinusoidal temperature distribution, the cylindrical panel may be deflected at the onset of loading and, for the most part, has no longer bifurcation-type buckling response. Furthermore, small values of preexisting external pressure have beneficial influences on the stability of nanocomposite cylindrical panels under nonuniform thermal loads.
Seduction, Aggression, and Frenchness in LA VIE PARISIENNE (1914–1918)
Authors: Ibáñez Aristondo Angélique
Published: August 2021

The article retraces how the notion of cultural singularity in sexuality was constructed and weaponized in the most popular French illustrated periodical of the First World War. It argues that La Vie Parisienne’s sublimation of romantic love, sex, and Frenchness worked as a cultural tactic that, while helping the readership cope with a devastating historical disruption, undermined at the same time claims for social change. The close analysis of works by illustrator Chéri Hérouard uncovers how nationalism and anxieties of sexual dispossession contributed to integrate a fraught notion of women’s sexual consent to a broader claim of cultural superiority. This article provides a critical approach to popular and visual representations of heterosexual and non-conjugal norms of desire, seduction, and sexuality in wartime France. It also offers a historical example of how the racialization and nationalisation of gender relations, discussed as ‘Gallic singularity’ in recent scholarship, trivialises masculine aggression and produces the ambivalence long associated with the notion of women’s sexual consent in France.
The Efficacy of Preserving Communal Tenure in South Africa
Authors: Mawere J. , Matshidze P. E. , Kugara S. L. , Madzivhandila T. S.
Published: August 2021

European colonialism and apartheid in South Africa included the alienation of land just as the restructuring of customary tenure. The reconstructed customary tenure vested title to land in the colonial and apartheid state in this way, merging sovereignty and property. The merger encouraged authoritative control of rural society. Customary tenure was argued to be communal and excluded individual rights. Regardless of the official rendition, customary tenure was dynamic, recognized individual use rights and “facilitated accumulation and differentiation.” In the present-day, customary tenure is perceived as unregulated capital, holding back the ability of the poor people to prosper. Thus, the relevance and place of customary tenure is in dispute. This article aims to examine the efficacy for preserving customary tenure, using Vhembe district as a case study. The article uses the exploratory qualitative approach to collect data.
Solidary Neighbors? The Involvement of Middle-Class Communities in the Governance of Security and Disorder in Brazil
Authors: Lopes Cleber , Lima Fabricio Silva , Melgaço Lucas
Published: August 2021

This study explores how residents govern security in two middle-class neighborhoods in Londrina, the fourth largest city in southern Brazil. Utilizing nodal governance theory, it analyses a security program called Solidary Neighbor ( Vizinho Solidário, in Portuguese) in both neighborhoods, in place since the early 2010s. Document analysis, direct observation, and interviews with 26 respondents comprising mostly residents, but also police officers, sex workers, and homeless people, were conducted to assess how the program works and what implications it has for the governance of public spaces. The findings show that the Solidary Neighbor program functions as a community governance node oriented toward reducing criminal opportunities with the use of technologies to monitor outsiders and displace sex workers and homeless people. The article concludes that particularly in contexts such as in Brazil, bottom-up security initiatives have the potential to produce hostile and exclusionary public spaces.
Goals of Care Discussions Over the Course of a Patient’s End of Life Admission: A Retrospective Study
Authors: Perera Natalie , Gold Michelle , O’Driscoll Lisa , Katz Naomi T.
Published: August 2021

Background:

As deaths in hospitals increase, clear discussions regarding resuscitation status and treatment limitations, referred to as goals of care (GOC), are vital. GOC may need revision as disease and patient priorities change over time. There is limited data about who is involved in GOC discussions, and how this changes as patients deteriorate in hospital.

Aims:

To review the timing and clinicians involved in GOC discussions for a cohort of patients who died in hospital.

Methods:

Retrospective observational audit of 80 consecutive end of life admissions between March 11th and April 9th, 2019.

Results:

Of 80 patients, 75 (93.6%) had GOC recorded during their admission, about half for ward-based non-burdensome symptom management or end-of-life care. GOC were revised in 68.0% of cases. Medical staff involved in initial versus final GOC discussions included home team junior doctor (54.7% versus 72.5%), home team consultant (37.3% versus 56.9%) and ICU doctor (16.0% versus 21.6%). For initial versus final GOC decisions, patients were involved in 34.7% versus 31.4%, and family in 53.3% versus 86.3%. Dying was documented for 92.0% of patients and this was documented to have been communicated to the family and patient in 98.6% and 19.5% of cases respectively.

Conclusions:

As patients deteriorated, family and senior clinician involvement in GOC discussions increased, but patient involvement did not. Junior doctors were most heavily involved in discussions. We advocate for further GOC training and modeling to enhance junior doctors’ confidence and competence in conducting and involving patients and families in GOC conversations.
A discrete manufacturing SCOS framework based on functional interval parameters and fuzzy QoS attributes using moving window FPA
Authors: Gao Jie , Yan Xianguo , Guo Hong
Published: August 2021

Manufacturing service composition and optimal selection (SCOS) is a key technology that improves resource utilization and reduces the cost in discrete manufacturing. However, the lack of evaluation of the service composition function and the unconformity of the actual composition vague characteristics, resulting in the incomplete evaluation of the service composition. Additionally, various optimization and selection algorithms have defects of premature convergence and low efficiency. At the same time, the fitness value distribution of the service composition has a non-linear characteristic. In this article, a framework called discrete manufacturing SCOS (DMSCOS) is proposed to overcome these issues. DMSCOS uses the functional interval parameter and fuzzy QoS attribute aware evaluation model (FIPFQA) to achieve composition evaluation and introduces a moving window flower pollination algorithm (MWFPA) to achieve optimization and selection for the non-linear characteristic population. Experiments show that DMSCOS has good performance for optimization and selection. The FIPFQA has a good effect on service composition evaluation. Furthermore, compared with two other extended algorithms, the proposed MWFPA performs better when addressing the optimal and selection problem.
Feline temporal lobe epilepsy: seven cases of hippocampal and piriform lobe necrosis in England and literature review
Authors: Scalia Bruno , Caine Abby , Pittaway Rachel , Cherubini Giunio Bruto
Published: August 2021

Case series summary

Seven cases of feline hippocampal and piriform lobe necrosis (FHN) are described, with particular emphasis on clinical, radiographic and histopathological correlations. FHN is an uncommon acute epileptic condition resembling human autoimmune limbic encephalitis and temporal lobe epilepsy. Seizures are typically focal and feature uni- or bilateral orofacial or head twitching, hypersalivation, lip smacking, mydriasis, vocalisation and motionless staring, with inter-ictal behavioural changes such as unprovoked aggression and rapid running. Emerging evidence supports an autoimmune aetiology, although disruption of hippocampal architecture secondary to brain neoplasia has also been recognised. Most commonly, however, the underlying cause remains unknown. Diagnosis is achieved clinically and with brain MRI; electroencephalography and voltage-gated potassium channel-complex autoantibodies are currently the subject of research. Affected cats are frequently refractory to conventional antiepileptic treatment.

Relevance and novel information

Following a review of the literature, including potential complicating factors and comparisons with human medicine, the hippocampus and piriform lobe are proposed as the neuroanatomical localisation for focal seizures with orofacial involvement in cats, regardless of aetiology.
Evaluation of test methods and face-sheet thickness effects in damage tolerance assessment of composite sandwich plates
Authors: Rajput Moeen S , Burman Magnus , Hallström Stefan
Published: August 2021

Composite sandwich materials provide high bending performance-to-weight ratios. However, these materials are vulnerable to impact damages which can drastically reduce their load-bearing capability. Presently there is a lack of standardised test methods for impact assessment. This study compares three different test methods for impact assessment; single skin compression after impact (CAI-SS), sandwich compression after impact (CAI-SW) and four-point bending-after-impact (BAI). The CAI-SS test method shows high compressive strength and strain at failure and the tesr is relatively easy to evaluate. For finite size plates with significant impact damage, the CAI-SS test method is recommended for post impact strength assessment. For large sandwich panels with relatively small impact damages the CAI-SW test method could be more relevant since it includes effects of panel asymmetry generated from the impact damage. The BAI test method may be recommended as an alternative to CAI but quite long specimens are required in order to assure compressive failure in the tested face-sheet, making the test both demanding and expensive. On the other hand, lower load levels are required to break the specimens and there is less need for precise machining during specimen manufacturing. A finite element model including progressive damage evolution was used to estimate the post impact strength. The simulations showed generally good agreement with the experiments.
‘Let them do PE!’ The ‘becoming’ of Swedish physical education in the age of COVID-19
Authors: Kamoga Seguya , Varea Valeria
Published: August 2021

Sweden received worldwide attention for its approach to managing the COVID-19 pandemic. Notably, throughout the pandemic, Sweden was one of the few countries that did not implement any lockdown measures. This meant that primary schools remained open and classes proceeded as usual, including the delivery of physical education (PE). This paper explores PE teachers’ perceptions of the effects of the COVID-19 pandemic on Swedish PE. Data were collected through semi-structured interviews with seven PE teachers. Results suggest that teaching PE during COVID-19 has led to disparate challenges and changes for teachers, including modifications in context, content, roles and responsibilities, as well as the handling of issues concerning physical contact and proximity among students and teachers. The conclusions of this study reveal that in the midst of the COVID-19 pandemic, the parameters of PE in Sweden are changing more rapidly now than ever before. Understanding how the pandemic has impacted the subject of PE and its delivery might create opportunities for further discussions, possible solutions and subsequent necessary adjustments in dealing with the ongoing COVID-19 situation.
Are you a neoliberal subject? On the uses and abuses of a concept
Authors: Watts Galen
Published: August 2021

A spate of social scientific literature gives the impression that societies in the twenty-first century are overrun with ‘neoliberal subjects’. But what does it actually mean to be a neoliberal subject? And in what ways does this concept relate to ‘neoliberalism’, more generally? In this article, I distinguish between four common ways of thinking about ‘neoliberalism’: (1) as a set of economic policies, (2) as a hegemonic ideological project, (3) as a political rationality and form of governmentality and (4) as a specific type of embodied subjectivity. I argue that while neoliberalisms (1), (2) and (3) potentially hold clear conceptual connections to one another – notwithstanding the quite real tensions between them – their relationship to neoliberalism (4) is often (although not always) tenuous at best. That is, the evidence routinely offered to demonstrate the existence of neoliberalism (4) bears almost no necessary relationship to neoliberalisms (1), (2) or (3). I conclude that, for both academic and political reasons, scholars should be more careful when invoking the monolithic notion of a ‘neoliberal subject’.
An Analysis of Impact of Anti-dumping Duties on India–China Trade
Authors: Mahajan Ashwani , Chand Phool , Pasumarthi Harsha Vardhan
Published: August 2021

India has imposed anti-dumping duties (ADDs) on a total of 155 commodities against China across many sectors to protect the domestic industry since 2001. The dumping of Chinese goods into Indian markets has led to the downfall and closure of many domestic industries. Under such circumstances, ADDs had been necessitated for protecting the domestic industry. As per the World Trade Organization (WTO) rules, imposition of ADDs on imports is permitted, provided that the affected country establishes that the domestic industry has suffered material injury by such imports. An elaborate discussion explaining the investigation pertaining to ADD and imposition of ADD in relation with WTO rules is presented in the present article. During the period between 2014 and 2018, ADD has been imposed on a total of 121 commodities. The study finds that ADDs have been partially effective in reducing the imports of the commodities.

A call to rethink the Global North university: Mobilising disabled students’ experiences through the encounter of Critical Disability Studies and Epistemologies of the South
Authors: Peruzzo Francesca
Published: August 2021

In the 1970s, disabled people and other marginalised social groups battled an exclusionary Global North university. Disability Studies emerged from those struggles as epistemologies shaped around a Westernised understanding of disability and inequalities, based on dialectic visions of progress and subjective liberation. Today, the advance of neoliberalism in universities, and its connection with colonial legacies, are embedded in different historical contingencies, and disabled students face new forms of discrimination. By merging analytical approaches from post-structural Critical Disability Studies and Epistemologies of the South, this article draws upon interviews with disabled students conducted in an Italian university to explore how neoliberal and capitalistic practices exclude certain knowledges and modalities of being university students. Through disabled students’ experiences, the article advances epistemologies that encompass processes of decolonisation and de-ableism of the university and argues for the Global North university to be an institution that can democratically reconcile polyhedral subjective possibilities of being.
