Projection Synchronization of a Class of Complex Chaotic Systems with Both Uncertainty and Disturbance
Authors: Sha Hongsheng , Wang Guijuan , Hao Tao , Wang Zuoxun
Published: July 2020

This paper mainly investigates the projection synchronization of complex chaotic systems with both uncertainty and disturbance. Using the linear feedback method and the uncertainty and disturbance estimation- (UDE-) based control method, the projection synchronization of such systems is realized by two steps. In the first step, a linear feedback controller is designed to control the nominal complex chaotic systems to achieve projection synchronization. An UDE-based controller is proposed to estimate the whole of uncertainty and disturbance in the second step. Finally, numerical simulations verify the feasibility and effectiveness of the control method.

This study focuses on the production and characterization of biodegradable handmade paper from the Sida rhombifolia plant (SRP) cellulose. Sida rhombifolia plant is a seasonal plant that grows in the equatorial and tropical climates. The studies carried out on this SRP were aimed at investigating the methods required for the production of handmade paper from SRP plant and also at determining the tensile strength. Four specimens of SRP paper of different additive labels S0 (no additive), S1 (starch and KOH), S2 (starch), and S3 (Foska liquid glue) were produced using the Kraft method. Tensile properties (stress at break, elongation at break, and Young’s modulus), the rate of water absorption, and the rate of moisture absorption were carried out. Results showed that the addition of potassium hydroxide considerably reduces Young’s modulus of SRP handmade paper (S1) while the Foska liquid glue (S3) significantly improves it. In addition, the addition of potassium hydroxide and Foska liquid substantially improves the water absorption properties of the paper S2 and S3, respectively. The adhesive liquid creates more porosity and consequently increases the absorption of water. The addition of potassium hydroxide and Foska liquid significantly embedded the rate of moisture absorption. From the results obtained, it can be concluded that the paper S3 can be used as packaging paper since it has better mechanical properties and moisture absorption.
Design and Synthesis of Reusable Nanoparticles for Reversible Chemisorption of Hexavalent Chromium Anions from Aqueous Media and Catalysis
Authors: Omwoma Lugasi Solomon
Published: July 2020

A magnetically active nanocomposite material has been synthesized from the reaction mixture of magnetite core iron nanoparticles electrostatically coated with SiO2, hydrotalcite nanosheets ([Eu8 (OH)20 (H2O)n]4+), and decatungstophosphate anion ([α-PW10O367−]). The resulting nanocomposite material, denoted as Fe3O4@SiO2@LEuH@PW10, is demonstrated to effectively adsorb chromate anions from aqueous solutions. The adsorption isotherms fit the Langmuir model with a capacity of 23 mmol·g−1 after 42 minutes at 25°C. The reaction is spontaneous at room temperature with 44.22 kJ·mol−1 of activation energy required. In addition, heating the chromate-adsorbed nanocomposite material at 40°C results in dissociation of the chromate anions from the nanocomposite material. As such, the recycled adsorbent Fe3O4@SiO2@LEuH@PW10 is reused for chromate removal in aqueous solutions for at least ten times without obvious loss of activity. This spontaneous reversible chemisorption mechanism for chromate adsorption provides a new pathway for separation and cleaning of industrial wastewater contaminated with chromate ions. The robust catalytic activity of the nanocomposite is also demonstrated.

Published: July 2020

The interest in face recognition studies has grown rapidly in the last decade. One of the most important problems in face recognition is the identification of ethnics of people. In this study, a new deep learning convolutional neural network is designed to create a new model that can recognize the ethnics of people through their facial features. The new dataset for ethnics of people consists of 3141 images collected from three different nationalities. To the best of our knowledge, this is the first image dataset collected for the ethnics of people and that dataset will be available for the research community. The new model was compared with two state-of-the-art models, VGG and Inception V3, and the validation accuracy was calculated for each convolutional neural network. The generated models have been tested through several images of people, and the results show that the best performance was achieved by our model with a verification accuracy of 96.9%.
Sinogram‐Affirmed Iterative Reconstruction Negatively Impacts the Risk Category Based on Agatston Score: A Study Combining Coronary Calcium Score Measurement and Coronary CT Angiography
Authors: Wang Wei , Zhao Yan E. , Qi Li , Zhou Chang Sheng , Lu Meng Jie , Yang Jian Xin , Zhang Long Jiang , Lu Guang Ming
Published: July 2020

Purpose. To assess the impact of sinogram‐affirmed iterative reconstruction (SAFIRE) on risk category for coronary artery disease by combining coronary calcium score measurement and coronary CT angiography (CCTA). Materials and Methods. Eighty‐nine patients (64.0% male) older than 18 years (64.4 ± 10.3 years) underwent coronary artery calcium scanning and prospectively ECG‐triggered sequential CCTA examination. All raw data acquired in coronary artery calcium scanning were reconstructed by both filtered back projection (FBP) and SAFIRE algorithms with 5 different levels. Objective image quality and calcium quantification were evaluated and compared between FBP and all SAFIRE levels by the Sphericity Assumed test or Greenhouse‐Geisser ε correction coefficient. Coronary artery stenosis was assessed in CCTA. Risk categories of all patients and of the patients with coronary artery stenosis in CCTA were compared between FBP and all SAFIRE levels by the Friedman test. Results. The reconstruction protocol from traditional FBP to SAFIRE 5 was associated with a gradual reduction in CT value and image noise (P < 0.001) but associated with a gradual improvement in the signal‐to‐noise ratio (P < 0.001). There was a gradual reduction in coronary calcification quantification (Agatston score: from 73.5 in FBP to 38.1 in SAFIRE 5, P < 0.001) from traditional FBP to SAFIRE 5. There was a significant difference for the risk category between FBP and all levels of SAFIRE in all patients (from 3.5 in FBP to 3.2 in SAFIRE 5, P < 0.001) and in the patients with coronary artery stenosis in CCTA (from 4.0 in FBP to 3.6 in SAFIRE 5, P < 0.001). Conclusions. SAFIRE significantly reduces coronary calcification quantification compared to FBP, resulting in the reduction of risk categories based on the Agatston score. The risk categories of the patients with coronary artery stenosis in CCTA may also decline. Thus, SAFIRE may lead risk categories to underestimate the existence of significant coronary artery stenosis.

Development of Fuzzy Level of Service Criteria for Bus Rapid Transit considering User Heterogeneities in China
Authors: Huo Yueying , Liu Jianrong , Zhang Jian , Li Xiaojuan
Published: July 2020

Level of service (LOS) analysis based on LOS criteria is essential for the planning, design, and operational evaluation of public transit. However, there are no systematic transit LOS criteria at present in China. Bus rapid transit (BRT) is receiving increasing attention worldwide. Therefore, this study addresses LOS criteria for BRT in China. Transit passengers are heterogeneous in their perceptions, needs, and behavior. The traditional hard LOS criteria have an inherent weakness, because of which the accuracy of an LOS analysis is limited. Thus, in this study, we initially conducted transit market segmentation to reduce heterogeneity and subsequently developed BRT fuzzy LOS criteria for different passenger groups. Using a smartphone-based transit travel survey system, we organized BRT passenger travel surveys on three BRT systems in China to collect data. Transit market segmentation was performed based on user perceptions; passengers were segmented into a calm passenger group and an anxious passenger group using the latent class model. Passenger arrival time, passenger wait time, and running speed of the bus were selected as service metrics to reflect the BRT’s LOS. BRT fuzzy LOS criteria for the three service metrics in the case of both the calm and anxious passenger groups were developed using fuzzy C-means clustering. The LOS criteria for the two groups of passengers fit their psychological characteristics and reflected their personalized travel needs. Fuzzy LOS criteria can describe to what extent service metric values belong to the adjacent LOS categories via the use of membership. Thus, fuzzy LOS criteria can overcome the weakness of hard LOS criteria.

Published: July 2020

A bidirectional functionally graded Sandwich (BFGSW) beam model made from three distinct materials is proposed and its dynamic behavior due to nonuniform motion of a moving point load is investigated for the first time. The beam consists of three layers, a homogeneous core, and two functionally graded face sheets with material properties varying in both the thickness and longitudinal directions by power gradation laws. Based on the first-order shear deformation beam theory, a finite beam element is derived and employed in computing dynamic response of the beam. The element which used the shear correction factor is simple with the stiffness and mass matrices evaluated analytically. The numerical result reveals that the material distribution plays an important role in the dynamic response of the beam, and the beam can be designed to meet the desired dynamic magnification factor by appropriately choosing the material grading indexes. A parametric study is carried out to highlight the effects of the material distribution, the beam layer thickness and aspect ratios, and the moving load speed on the dynamic characteristics. The influence of acceleration and deceleration of the moving load on the dynamic behavior of the beam is also examined and highlighted.

Published: July 2020

With the advancement in ICT, web search engines have become a preferred source to find health-related information published over the Internet. Google alone receives more than one billion health-related queries on a daily basis. However, in order to provide the results most relevant to the user, WSEs maintain the users’ profiles. These profiles may contain private and sensitive information such as the user’s health condition, disease status, and others. Health-related queries contain privacy-sensitive information that may infringe user’s privacy, as the identity of a user is exposed and may be misused by the WSE and third parties. This raises serious concerns since the identity of a user is exposed and may be misused by third parties. One well-known solution to preserve privacy involves issuing the queries via peer-to-peer private information retrieval protocol, such as useless user profile (UUP), thereby hiding the user’s identity from the WSE. This paper investigates the level of protection offered by UUP. For this purpose, we present QuPiD (query profile distance) attack: a machine learning-based attack that evaluates the effectiveness of UUP in privacy protection. QuPiD attack determines the distance between the user’s profile (web search history) and upcoming query using our proposed novel feature vector. The experiments were conducted using ten classification algorithms belonging to the tree-based, rule-based, lazy learner, metaheuristic, and Bayesian families for the sake of comparison. Furthermore, two subsets of an America Online dataset (noisy and clean datasets) were used for experimentation. The results show that the proposed QuPiD attack associates more than 70% queries to the correct user with a precision of over 72% for the clean dataset, while for the noisy dataset, the proposed QuPiD attack associates more than 40% queries to the correct user with 70% precision.

Published: July 2020

The base transceiver stations (BTS) are telecom infrastructures that facilitate wireless communication between the subscriber device and the telecom operator networks. They are deployed in suitable places having a lot of freely propagating ambient radio frequency (RF) and solar energies. This paper is aimed at converting received ambient environmental energy into usable electricity to power the stations. We proposed a hybrid energy harvesting system that can collect energy from RF and solar energies at the same time. The sources are combined to provide to a significant amount, to contribute to operational expenditures that reduce energy costs, and to improve the energy efficiency of the base station sites in rural areas from the most common renewable resources since the base stations are major consumers of cellular networks. The hybrid systems are designed with circuits, simulated, and compared to show their good performance to the base stations. PSIM, PROTEUS, and MATLAB software are used to simulate for evaluating the voltage and the current output of the hybrid systems that meet the power requirements. The design and simulation results show the feasibility of our proposed method with the battery storage that can be deployed not only in real base stations but also for other electrical operated systems.

Authors: Li Chunping , Hao Huibing , Xu Fang , Zhao Guotao
Published: July 2020

This paper focuses on system reliability analysis with dependent competing failure process due to soft failure and hard failure. Some new probabilistic methods based on cumulative shock model and nonlinear Wiener process under different shifting thresholds situation are obtained. Considering that nonlinearity exists extensively in practice, the continuous soft failure process is governed by random effected nonlinear Wiener process. Firstly, reliability evaluation models for hard failure and soft failure are obtained under the cumulative shock, respectively. Furthermore, some system reliability models under different shifting thresholds situation are studied, in which failure threshold will decrease after a certain number of shocks. A real numerical example about fatigue crack growth dataset is carried out to demonstrate the proposed procedure. Numerical results indicate that both random shocks and shifting threshold have significant effect on system reliability. Finally, some sensitivity analysis are also been given.

Background. Cardiac allograft vasculopathy (CAV) remains the Achilles’ heel of long-term survival after heart transplantation (HTx). The severity and extent of CAV is graded with conventional coronary angiography (COR) which has several limitations. Recently, vessel<?tex id="Q1" staff-cmt="“It is very important for the corresponding author to have a linked ORCID (Open Researcher and Contributor ID) account on MTS.

Purpose. The present study assessed the usefulness of vFFR to detect CAV in HTx recipients. Methods. In HTx patients referred for annual check-up, undergoing surveillance COR, the extent of CAV was graded according to the criteria proposed by the international society of heart and lung transplantation (ISHLT). In addition, three-dimensional coronary geometries were constructed from COR to calculate pressure losses using vFFR. Results. In 65 HTx patients with a mean age of 53.7 ± 10.1 years, 8.5 years (IQR 1.90, 15.2) years after HTx, a total number of 173 vessels (59 LAD, 61 LCX, and 53 RCA) were analyzed. The mean vFFR was 0.84 ± 0.15 and median was 0.88 (IQR 0.79, 0.94). A vFFR ≤ 0.80 was present in 24 patients (48 vessels). HTx patients with a history of ischemic cardiomyopathy (ICMP) had numerically lower vFFR as compared to those with non-ICMP (0.70 ± 0.22 vs. 0.79 ± 0.13, p=0.06). The use of vFFR reclassified 31.9% of patients compared to the anatomical ISHLT criteria. Despite a CAV score of 0, a pathological vFFR ≤ 0.80 was detected in 8 patients (34.8%). Conclusion. The impairment in epicardial conductance assessed by vFFR in a subgroup of patients without CAV according to standard ISHLT criteria suggests the presence of a diffuse vasculopathy undetectable by conventional angiography. Therefore, we speculate that vFFR may be useful in risk stratification after HTx.

Published: July 2020

A 46-year-old female with a history of 5 months of progressive painless visual loss in the left eye was found to have an optic nerve sheath meningioma. Optical coherence tomography angiography showed a reduction in the superficial capillary plexus density consistent with her visual field defect and peripapillary retinal nerve fiber layer thinning. Moreover, abnormalities in the choriocapillaris were found in the affected eye compared to the fellow eye. Possible explanations for these findings are discussed. Further studies and a consistent number of cases are needed to correctly assess the impairment of ocular blood flow in optic nerve sheath meningioma.

Published: July 2020

We report a case of full-thickness macular hole (FTMH) which developed during follow-up for Coats disease. To our knowledge, this is the first report on a case of FTMH which developed during follow-up for Coats disease. A 17-year-old boy was referred to our institution with blurred vision in his left eye. Fundus examination showed yellowish subretinal exudates with overlying telangiectatic retinal vessels in the temporal periphery in the left eye; the right eye was normal. Fluorescein angiography revealed diffusion indicative of temporal peripheral vascular leakage. We made a diagnosis of stage 2A Coats disease and performed argon laser photocoagulation (PC). Moreover, he received intravitreal injection of anti-vascular endothelial growth factor. At 30 months after the first visit, the best-corrected visual acuity (BCVA) of the left eye worsened to 20/50. We observed tensioned internal limiting membrane (ILM), serous macular detachment (SMD) and retinal thinning; the intraretinal exudate remained. We performed PC and at 36 months after the first visit, BCVA further declined to 20/63 in his left eye and FTMH was observed. We then performed a 27-gauge pars plana vitrectomy and ILM peeling following which the FTMH was found to have closed by 4 days after vitrectomy. SMD gradually decreased, and BCVA improved to 20/20. Chronic inflammation by peripheral vascular leakage and PC application might have caused FTMH. In this case, the vitrectomy for FTMH with Coats disease provided good visual and anatomic outcomes.

Understanding Requires Tracking: Noise and Knowledge Interact in Bilingual Comprehension
Authors: Blanco-Elorrieta Esti , Ding Nai , Pylkkänen Liina , Poeppel David
Published: July 2020

Understanding speech in noise is a fundamental challenge for speech comprehension. This perceptual demand is amplified in a second language: It is a common experience in bars, train stations, and other noisy environments that degraded signal quality severely compromises second language comprehension. Through a novel design, paired with a carefully selected participant profile, we independently assessed signal-driven and knowledge-driven contributions to the brain bases of first versus second language processing. We were able to dissociate the neural processes driven by the speech signal from the processes that come from speakers' knowledge of their first versus second languages. The neurophysiological data show that, in combination with impaired access to top–down linguistic information in the second language, the locus of bilinguals' difficulty in understanding second language speech in noisy conditions arises from a failure to successfully perform a basic, low-level process: cortical entrainment to speech signals above the syllabic level.

Thalictrum mairei (Ranunculaceae) is synonymous with T. foliolosum, not T. leuconotum

Authors: ZENG YOU-PAI , YUAN QIONG , YANG QIN-ER
Published: July 2020

Thalictrum mairei (Ranunculaceae) has been previously placed in synonymy with T. leuconotum based on non-type material of the former name. Critical examination of the type material of T. mairei reveals that it is actually synonymous with T. foliolosum, not T. leuconotum. We therefore reduce T. mairei to the synonymy of T. foliolosum herein. We also clarify morphological distinction among T. leuconotum, T. sinomacrostigma, T. uncatum var. angustialatum and T. uncatum var. uncatum. Lectotypification is proposed for T. falconeri (another synonym of T. foliolosum) and T. foliolosum.

Published: July 2020

A small unidentified species of Navicula was observed in sandy sediments of a Quaternary spring near Lodz in Central Poland. The species was thoroughly analyzed using light (LM) and scanning electron (SEM) microscopy. It was compared to established species of Navicula from available published sources and its assignment to an established taxon was unsuccessful. Hence, we decided to describe it as a species new for science and the name Navicula fontana sp. nov. is proposed. Navicula fontana sp. nov. was compared to several established species, e.g. N. microdigitoradiata, N. meulemansii, in terms of size dimension range, morphology, ultrastructure, and autecology. Firstly, it differs in terms of autecology living in freshwater, whereas the others thrive in brackish water habitats. Although the type habitat of N. fontana sp. nov. is in a spring, we also observed it in headwaters of rivers with high water quality.

The Spatial Distribution of Ocean Waves in Tropical Cyclones
Authors: Tamizi Ali , Young Ian R.
Published: July 2020

The spatial structure of both the wind and wave fields within tropical cyclones is investigated using two large databases. The first of these was compiled from global overpasses of tropical cyclones by satellite altimeters. The second dataset consists of an extensive collection of North American buoy measurements during the passage of tropical cyclones (hurricanes). The combined datasets confirm the vortex structure of the tropical cyclone wind field with the strongest winds to the right (Northern Hemisphere) of the storm. The wave field largely mirrors the wind field but with greater right–left asymmetry that results from the extended fetch to the right of the translating tropical cyclone. The extensive in situ buoy database confirms previous studies indicating that the one-dimensional spectra are generally unimodal. The directional spectra are, however, directionally skewed, consisting of remotely generated waves radiating out from the center of the storm and locally generated wind sea. The one-dimensional wave spectra have many similarities to fetch-limited cases, although for a given peak frequency the spectra contain less energy than for a fetch-limited case. This result is consistent with the fact that much of the wave field is dominated by remotely generated waves.

Published: July 2020

Binary phospholipid bilayers composed of 1,2-dioleoyl-sn-glycero-3-phosphocholine and 1,2-palmitoyl-sn-glycero-3-phosphocholine (DPPC) were studied by Raman spectroscopy and differential scanning calorimetry (DSC). We examined features in Raman scattering spectra that are sensitive to the lipid phase and, therefore, could indicate the phase coexistence. It was found that the low-frequency half-width of half-maximum (LHWHM) of the 2850 cm−1 Raman line, corresponding to the symmetric CH2 stretching vibrations, unequivocally reveals the coexisting phospholipids in ordered and disordered conformational states, which correspond to ordered and disordered phases coexistence, in the DPPC mole concentration range from 0.4 to 0.9. The phase coexistence in this concentration range was supported by the particular concentration behavior of the ratio between the intensities of the 2880 cm−1 antisymmetric CH2 vibration line and the 2850 cm−1 symmetric one. It was also shown that the spectral shape of the 1300 cm−1 Raman line, corresponding to the CH2 twisting vibrations, is a good indicator for the phase state and phase coexistence in the phospholipid bilayers. Comparison with the DSC curves confirmed that in the DPPC mole concentration range from 0.4 to 0.9, the two phase transition peaks are observed in DSC curve, those positions are independent of the DPPC concentration. The outcome of the study is the robust label-free contactless approach for the detection of the lipid phase separation, which can be realized with the micrometer resolution.

Published: July 2020

Recent evidence suggests that microplastic particles are pervasive and potentially of great risk to both animal and human health. The California legislature has responded to this information by enacting two new bills that require quantification of microplastics in various media and development of new management strategies to address microplastic pollution. However, there are several scientific gaps that impede the development and implementation of necessary management strategies to address microplastic pollution. In this paper, we use the California experience as a case study to provide perspective on those science gaps, the current barriers to science affecting management, and the actions scientists can take to best ensure their efforts are of greatest value to policymakers and the management community.
Technology Acquisition in China’s Automobile Industry: Focusing on the Local Producers
Authors: Dong Jinglin , Mah Jai S.
Published: July 2020

China’s automobile industry has succeeded remarkably since the 1980s. The Chinese government welcomed foreign automobile companies to form joint ventures. The local automobile companies began to enter the market in the late 1990s. To compete with the foreign rivals, they needed to acquire advanced technologies. Meanwhile, technology transfer through foreign direct investment (FDI) inflows was not so successful. Some of the local automobile producers developed their technologies through FDI outflows. The large local automobile producers have paid much attention to their own research and development (R&D) activities. China has tried hard to build its human capital. Acquiring intellectual property rights from foreign manufacturers has been another way for the local producers to acquire advanced technologies. They have also tried to establish partnerships with the local technology groups. The ways in which the local automobile companies acquired advanced technologies may provide meaningful policy implications for the other technology-intensive industries and developing countries trying to develop the automobile industry.
Empirical analysis of the impact of financial development on the income gap between urban and rural residents in the context of large data using fuzzy Kmeans clustering algorithm
Authors: Li Yao
Published: July 2020

With the rise of the tertiary industry, the financial industry has achieved unprecedented development, which is mainly reflected in the rapid growth of economic aggregate, the increasingly balanced financial structure system and the increasingly diversified financial products. However, with the rapid development of financial industry, the income of urban and rural residents is increasingly unbalanced. The increasing income gap between urban and rural areas has caused a large number of adverse phenomena in the process of economic development, seriously affecting the income distribution of the people and even causing social instability. Therefore, in today’s big data era, it is necessary to systematically study and analyze the impact of financial industry development on the national income gap between urban and rural areas. At the same time, it is of great significance to improve the problem of excessive income gap between urban and rural areas. This paper mainly analyses the relationship between the three effects of the development of financial industry and the income gap between urban and rural residents. In the empirical aspect, the paper creatively uses the fuzzy Kmeans clustering algorithm to regression analysis the panel data of a certain area from 2010 to 2018. At the same time, in the empirical data analysis, this paper creatively replaces the European norm measure of the Kmeans clustering algorithm with the AE measure, and puts forward a proposal. The index of financial development level is based on the proportion of loans from financial institutions. Through theoretical and empirical analysis, this paper draws the following conclusions: the financial scale in the financial industry will have a huge impact on the income gap between urban and rural areas. Finally, based on the above problems and current situation, this paper puts forward relevant improvement suggestions.
Occlusal Features and TMJ Clicking: A 30-Year Evaluation from a Cohort Study
Authors: Olliver S.J. , Broadbent J.M. , Thomson W.M. , Farella M.
Published: July 2020

Occlusal features that deviate from normative values have been historically considered risk factors for temporomandibular joint (TMJ) disorders. Nowadays, a putative association between dental occlusion and TMJ disorders remains controversial, with research findings on associations being inconsistent and inconclusive. We hypothesized that putative occlusal features identified during adolescence are associated with TMJ clicking later in life. The Dunedin Multidisciplinary Health and Development Study is a longitudinal birth cohort study investigation of 1,037 children (48.4% female) born in Dunedin, New Zealand, between April 1, 1972, and March 31, 1973, and assessed repeatedly since then. Associations between posterior crossbite, overbite, and overjet at age 15, as well as both self-reported and clinically assessed TMJ clicking sounds at age 45, were studied. Data were analyzed using multivariate logistic regression, after controlling for sex, emotional style, self-reports of tooth clenching and sleep bruxism, and history of orthodontic treatment. Self-reported and examiner-reported TMJ clicking at age 45 affected 18.3% and 23.8% of the study sample, respectively, and were not associated with the presence of a posterior crossbite or abnormal overjet/overbite values during adolescence. Self-reported history of tooth clenching and emotional style were associated with self-reported TMJ clicking later in life. In addition, there is a suggestion that high overbite during adolescence is negatively associated with TMJ clicking later in life. A history of orthodontic treatment was not associated with TMJ clicking. Abnormal occlusal features, such as posterior crossbite and high and low overjet/overbite in adolescence, are not associated with higher prevalence of TMJ clicking later in life. Personality also appears to influence self-reports of TMJ clicking later in life.
Discontent With What? Linking Self-Centered and Society-Centered Discontent to Populist Party Support
Authors: Giebler Heiko , Hirsch Magdalena , Schürmann Benjamin , Veit Susanne
Published: July 2020

Previous studies aimed at explaining populist support emphasize the crucial role of populist attitudes and ideology among the general population. With respect to the role of discontent and grievances as drivers of populist support—often at the heart of theoretical work on populism—however, empirical results are rather mixed. We argue that the apparent contradictions are partly due to insufficient conceptualization of discontent. We distinguish between societal-centered discontent, which is more based on a general, negative subjective assessment of society, and self-centered discontent that expresses a negative assessment of one’s personal situation. In line with our expectations, regression results for Germany confirm that society-centered discontent, but not self-centered discontent, is important for populist party support. Moreover, we find that society-centered discontent also moderates the relation between populist attitudes and populist support. We conclude that beyond ideologies, populism capitalizes on the cultivation of collective—but not individual—discontent.
Safety evaluation of freeway interchange merging areas based on driver workload theory
Authors: Hu Jiangbi , He Lucheng , Wang Ronghua
Published: July 2020

Prior safety evaluations of interchange merging areas have mostly focused on traffic conflicts and operating speeds, without considering how these factors can influence the driver workload. Researches regarding the level of driver workload have largely concentrated on urban roads, tunnel sections, and basic freeway segments, without considering the impact of merging traffic flows on safety. Therefore, this study has investigated how merging vehicles can impact through-driver workload and safety. Three independent field experiments were conducted on freeways, involving 18 drivers and 17 interchanges. The results showed that the vehicles merging onto freeway impact driver workload and driving performance, generating potential risk that cannot be ignored. Merging into the mainline traffic flow increases the through-driver workload to a higher level or even exceeds the safety threshold, despite there being better geometrical conditions of interchanges than those of basic freeway segments. When the volume of merging vehicles exceeds 564 pcu/h or the traffic saturation is above 0.485, driver workload rises above the safety thresholds and the driving risk is elevated, which potentially would lead to crashes. This study offers insights for more effective segment division of operating speed prediction, and dynamic risk management with regard to interchange safety.
Making something out of nothing: Breaching everyday life by standing still in a public place
Authors: Stanley Steven , Smith Robin James , Ford Eleanor , Jones Joshua
Published: July 2020

Public displays of stillness and silence are increasingly found in contemporary life, yet have seldom been examined as social phenomena in their own right. We analyse people’s accomplishment, treatment and negotiation of an encounter with people ‘doing nothing’ – a breaching experiment comprising a group of students standing still in a city centre – and provide a granular description of the bodily practices whereby passers-by make ‘something’ out of ‘nothing’. Our ethnomethodological analysis of video recordings of the event demonstrates three practices for doing embodied noticing - looking back; slowing and pausing; stopping still - and illustrates how passers-by engage in ‘audiencing’ and ‘performing’. We propose breaching experiments as creative research and teaching interventions and discuss the socio-cultural, pedagogic and political implications of our analysis for studies of participation in public settings, especially where stillness, silence and ‘nothing’ feature.
The prevalence of peripartum depression and its relationship to mode of delivery and other factors among mothers in Ixopo, Kwazulu-Natal, South Africa
Authors: Duma Noxolo , Madiba Thandinkosi
Published: July 2020

Peripartum depression is a common mental health condition among mothers, occurring between 4 and 6 weeks post-delivery. This study sought to evaluate the influence that mode of delivery and other related factors have on the development of peripartum depression. The study was carried out in Ixopo, in the KwaZulu-Natal province of South Africa. All women whose infants had been delivered within 4–6 weeks of the study were included until the sample size of 276 was reached. A demographic questionnaire and an Edinburgh postnatal depression scale were administered. Mothers with Edinburgh postnatal depression scale scores of ⩾10 were considered to be suffering from peripartum depression, and peripartum depression was ruled out in those with a score of <10. A total of 110 mothers had Edinburgh postnatal depression scale score ⩾10, thus presenting a prevalence of 39.9%. Of these, 51 (46.4%) had undergone normal vaginal delivery and 59 had a Caesarean section (53.6%). Of the latter group, 23 had elective Caesarean section and 36 had emergency Caesarean section. Logistic regression showed no significant association between peripartum depression and mode of delivery ( p = .074); women who had delivered their child by emergency Caesarean section were three times more likely to develop peripartum depression compared to those who had delivered via normal vaginal delivery (odds ratio: 2.733, confidence interval: 1.002–7.452). Unemployment was found to have a statistically significant association with peripartum depression ( p = .003) and single motherhood was not associated ( p = .425). Emergency Caesarean sections and unemployment were shown to be risk factors for peripartum depression.
