Sensory Processing and Autistic Traits: Mediation Effect of Frontal Alpha Asymmetry
Authors: Yoon Deukgeun , Kim Eun Young
Published: January 2023

A sensory processing approach can be used to intervene with behaviours in individuals with autistic symptoms. However, neural mechanisms linking sensory processing patterns and autistic features are less understood. The purpose of this study was to investigate whether frontal alpha asymmetry could mediate the relationship between atypical sensory processing and autistic traits. Seventy-three neurotypical young adults were included in this study. Resting-state brain activity was recorded using electroencephalography. After the recording, participants completed the Adolescent/Adult Sensory Profile and the Autism-Spectrum Quotient. Frontal alpha asymmetry was calculated by subtracting left frontal alpha power from right frontal alpha power. Correlation analysis was performed to find which sensory processing patterns were related to frontal alpha asymmetry and autistic traits. Mediation analysis was then conducted with sensory avoiding patterns as an independent variable, autistic traits as a dependent variable, and frontal alpha asymmetry as a mediator. Interrelations between higher sensation avoiding patterns, greater right-sided cortical activity, and increased autistic traits were found. The sensation avoiding patterns affected autistic traits directly and indirectly through right-sided cortical activity. Findings of the current study demonstrate a mediating role of frontal alpha asymmetry in the relationship between sensation avoiding patterns and autistic traits in neurotypical adults. This study suggests that sensation avoiding patterns and withdrawal-related emotions, which are associated with right-sided cortical activity, need to be considered to improve autism symptoms.

Adaptive Noise Reduction Algorithm Based on SPP and NMF for Environmental Sound Event Recognition under Low-SNR Conditions
Authors: Luo Li-Yan , Guo Shu-Ting , Wang Mei , Qiu Hong-Bing , Liu Zheng-Hong
Published: January 2023

Nonnegative matrix factorization- (NMF-) based noise reduction methods can effectively improve the performance of environmental sound recognition. However, when the environmental sound overlaps highly with the noise, the spectral line loss and noise residue will occur in the low signal-to-noise ratio (SNR) condition. An adaptive noise reduction algorithm was proposed in this paper. First, noisy environmental sound is separated into estimated noise and environmental sound using NMF. Then, the estimated noise is used to calculate sound presence probability (SPP), which is adapted to decrease spectral line loss and achieve accurately estimated noise. Subsequently, the estimated noise combines with noisy environmental sound to obtain the estimated environmental sound. Finally, SPP is applied to reduce residual noise in the estimated environmental sound and reconstruct the environmental sound. The simulation results demonstrate that the proposed algorithm outperforms the traditional algorithms and NMF-based methods in terms of perceptual evaluation of speech quality (PESQ) and global SNR with increase of X% and X%, respectively. Moreover, the proposed method can effectively improve the environmental sound recognition rate. Particularly, the proposed method makes a 16.2% increase of F1-score in car horn recognition under the realistic acoustic condition.

Published: January 2023

Objective. To investigate the relationship between peripheral blood total bilirubin (TBIL) levels and the risk of primary open-angle glaucoma (POAG). Methods. This study was a cross-sectional, case-control study design. Between April 2021 and January 2022, 198 POAG patients and 205 healthy subjects were recruited from the EENT Hospital of Fudan University. Their clinical information (intraocular pressure, central corneal thickness, vertical cup-disk ratios (VCDR), and axial length) and demographic data were collected. Serum levels of TBIL were measured in enzymes using a Roche C702 biochemical analyzer. The POAG subgroups were classified by gender and VCDR: mild (

VCDR
≤
0.64

), moderate (

VCDR
≤
0.85

), and severe (

VCDR
>
0.85

). Univariate and multivariate logistic regression analyses were performed. Results. The level of TBIL (

11.58
±
5.16

 μmol/L) in the POAG group was higher than that in the control group (

10.18
±
3.38

 μmol/L;

p
<
0.05

). In the male subgroup, TBIL was also significantly higher than in the normal control group; TBIL levels were lower in the mild subgroup (

10.82
±
4.48

 μmol/L), followed by the moderate subgroup (

12.00
±
5.55

 μmol/L) and the severe subgroup (

14.47
±
5.45

 μmol/L). The results of the multivariate logistic regression analysis showed that high TBIL levels were a risk factor for male POAG, at 1.126 (95% CI 1.009–1.256). Pearson’s analysis revealed that TBIL was positively correlated with intraocular pressure (

r
=
0.134

,

p
=
0.012

), VCDR (

r
=
0.142

,

p
=
0.046

), anterior chamber depth (

r
=
0.190

,

p
=
0.014

), and axial length (

r
=
0.179

,

p
=
0.019

) in the patients. However, no statistical difference (

p
<
0.05

) was observed in the female patients with POAG. Conclusion. The results showed that high levels of TBIL may be related to the pathogenesis of POAG and that the severity of the disease is positively correlated, especially in male patients.

Published: January 2023

The dye contamination of water is a global concern in the environment. In this study, the photocatalytic technology and membrane module were combined to improve the surface distribution of the active species of the catalyst for better degradation of the methylene blue (MB) dye under visible light. ZnSn(OH)6 was chosen due to carbon’s complex metal oxide doped to facilitate the application under visible light. The numerous characterizations were analyzed in the composites to verify the consistency of the optimum degradation of MB over the catalyst coated on the membrane. During the preparation of the ZnSn(OH)6 composite, the results confirmed that different reaction times and amounts of sodium hydroxide significantly affected the pollutant’s degradation. The carbon-doped composite denoted the largest surface area and increased the catalyst’s reactive sites on the membrane. The photocatalytic activity test showed that 1% carbon doped on ZnSn(OH)6 prepared at 160°C by hydrothermal method coated on the membrane had the optimal degradation of 89.74% of MB. This study contributes to the ongoing study and development of photocatalytic membranes for the photodegradation of wastewater treatment.

Published: January 2023

In this study, natural convection heat transfer of a water based nanofluid inside a square cavity is numerically investigated for two different orientations of a wall-heated cavity. The enclosure is heated by applying a constant heat flux while cooled at ambient conditions. Lattice
Boltzmann method (LBM) is used to simulate nanofluid natural convection. The Brownian motion of nanoparticles is considered. LBM simulation is validated by comparison with experimental and numerical results of the literature. The effect of Rayleigh number (Ra = 103, 104,
105, 106), Biot number (Bi = 0.1, 1, 10, 100) and volume fraction of nanoparticles (Φ = 0, 1, 3 and 5%) on the isotherms, streamlines, velocity components, local and Nusselt number is analyzed for two oriented cavities. The bottom-heated cavity shows
higher heat transfer rate than that of the cavity heated from the sidewall. The average Nusselt number increases by up to 6.81%. Furthermore, Biot number, Rayleigh number, and volume fraction of nanoparticles show significant effects on the heat transfer rate.

Published: January 2023

Cross nanofluidic model yields extraordinary results and describes the behaviour of nanofluid at very high and very low shear rate. In this paper infinite shear rate viscosity model of cross nanofluid flow containing nanoparticles and motile gyrotactic microorganisms over three dimensional
horizontal cylinder is taken. In this attempt simultaneous utilization of nanoparticles along with motile microorganisms attached mathematical model of cross fluid and three-dimensional geometry of cylinder has been carried out as an innovation. For the inspection of velocity profile of cross
nanofluid inclined magnetic field is scrutinized. Temperature of Cross nanofluid and its concentration is also carried out with several facts. Mass flux and heat flux values for motile microorganisms and nanoparticles are calculated through statistical graphs. This attempt reveals that small
variation of Brownian motion parameter gives lower concentration of nanoparticle about 80.21% and 78.44% reduction is found in concentration of motile microorganisms.

Authors: Gireesha B. J. , Anitha L.
Published: January 2023

The present work examines the flow and thermal energy process in conducting couple stress nanofluid flows through an oblique microchannel. The microchannel is embedded with permeable medium and thermal radiation is implemented. The microchannel boundaries retain the slip boundary conditions.
The impact of buoyancy force and magnetic field are incorporated. The temperature dependent heat source effect was also taken into account. The momentum equation has been made by the permeability of the porous medium. The equations are modeled and non-dimensionalized using non-dimensional
entities and further solved with the aid of the Runge-Kutta Fehlberg method and the shooting procedure. The detailed discussions about the importance of the effective parameters on entropy generation, the Bejan number have been observed through graphs. The findings of the examination depict
that rise in radiation parameter augments the entropy generation and the Bejan number in the channel. The entropy generation and Bejan number diminishes with inflation of the permeability parameter.

Authors: Das Subrata , Mondal Hiranmoy , Kundu Prabir Kumar
Published: January 2023

This study discussed the mixed convection with thermal radiation on nanofluid flow with magnetic field and mass transfer with heat source over an inclined stretching cylinder in the presence of thermal conductivity. The governing equations in cylindrical form are transformed into the
system of ODE and solved mathematically by spectral quasilinearization method (SQLM). The governing parameters velocity, temperature and concentration profile are derived using this new approach. Here it is mention that due to Hartman number (Ha) and relaxation to retardation time ratio (λ1),
the velocity decreases but temperature enhanced in the boundary layer but in opposite effect on higher value of curvature parameter (γ) and thermal bouncy (λT) parameter. Here also observed convergence and accuracy in velocity and temperature profile.
The SQLM is used to find out the solution of convergent series and various effect are shown graphically.
Effect of Cross Thermal Buoyancy on Cu–H2O Nanofluid Flow Over Bluff Objects at Low Reynolds Numbers
Authors: Garai Sourav , Kumar Chandan , Chatterjee Dipankar , Mondal Bittagopal
Published: January 2023

Increasing the solid volume fraction (φ) in a nanofluid may trigger the vortex shedding around a bluff object even for a low Reynolds number (Re) steady regime. The cross thermal buoyancy may also trigger the vortex shedding around bluff objects at low Re.
When the nanofluid flow is subjected to cross buoyancy, the initiation of the vortex shedding process around bluff objects could be accelerated. For a given range of Re, thermal buoyancy and solid volume fraction decide the characteristics of the flow. Both these two parameters can
separately have a critical value at which the shedding process initiates. However, the presence of one parameter could affect the other significantly. In order to substantiate the above facts, a two-dimensional numerical simulation is performed to study the effect of cross thermal buoyancy
on the free stream nanofluid (Cu–H2O) flow over two-dimensional square and circular cylinders. The initiation of the shedding process is observed for 10 ≤ Re ≤ 30 and 0% ≤ φ ≤ 10% through computation of the critical Richardson numbers for all
the φ in the range. The relevant flow and thermal parameters are also computed to further establish the facts.

In this present research, suspensions of gyrotactic micro-organisms on non-newtonian carreau nanofluid with activation energy and binary chemical reaction is examined which is implanted under Darcy Forchhiemer porous medium. Similarity transformations are used to convert the governing
equation into a highly nonlinear ODE’s. Fifth-order Runge Kutta-Fehlberg method using shooting technique is utilized to solve ODE’s. Velocity, temperature, concentration, and density of motile gyrotactic microorganisms profile were depicted graphically and explained briefly. It
is observed that activation energy enhances the concentration profile of both pseudoplastic and dilatant fluids. Present results is compared with previously published work which is found to be in good agreement.
Heat Transfer and Transport Aspects of a ZnO/Ethylene Glycol-Water Nanofluid Through a Nonlinearly Stretching Sheet
Authors: Agrawal Rashmi , Kaswan Pradeep
Published: January 2023

This section proposes investigating the heat transfer and transport phenomena of nanofluid passing through a non-linear stretching sheet. The 50%:50% water-ethylene glycol mixture is accepted as a base fluid to prepare a nanofluid. The influences of viscous dissipation, Joule heating,
and thermal radiation in modelling are further exerted into attention. For converting partial differential systems to ordinary systems, a transformation technique is adopted. For the validation part, the numerical solution is computed by embracing a fourth-order exactness program (Bvp4c) and
compared to the previously published literature. When modest quantities of zinc oxide nanoparticles are introduced to a mixture of water and ethylene glycol (EG), the effect on heat transfer relative to the base fluid is also noticeable. Furthermore, the influence of flow rate change in nanoparticle
concentration on heat transfer performance is investigated. Graphical decisions reveal the values of miscellaneous-arising parameters on the velocity, temperature profile. The heat transfer rate is higher for the non-linear stretching surface than the flat surface. In comparison to nanofluid,
a mixture of ethylene glycol-water with ZnO nanoparticles has superior cooling capability than the ZnO/water nanofluid.
Thermal Radiation and Chemical Reaction Effects of Unsteady Magnetohydrodynamic Dissipative Squeezing Flow of Casson Nanofluid Over Horizontal Channel
Authors: Pradeep Kumar Bavanasi , Suneetha Sangapatnam
Published: January 2023

This work investigates the effects of chemical reaction and thermal radiation on the magnetohydrodynamic (MHD) squeezing Casson fluid flow through a porous media under the influence of heat absorption, which is motivated by the application of flow in industrial issues. The flow is generated
by the compression of two plates together. The transformation of partial differential equations (PDEs) to ordinary differential equations (ODEs) is accomplished via similarity variables. The numerical analysis was carried out using the shooting method, which involved solving the competent
controlling equations with dominant parameters for a thin liquid film. It is necessary to compare the numerical findings with previous research to verify the present solutions. The findings reveal that the velocity and wall shear stress increase as the distance between the two plates becomes
closer. The higher values of squeezing number diminish the squeezing force on the fluid flow, which in turn reduces the thermal field. The thinner temperature boundary layer corresponds to the lower values of thermal diffusivity and it shows the higher values of temperature gradient for the
increasing values of β. Due to the presence of stronger Lorentz forces the temperature and velocity fields behave like decreasing functions of Hartmann number.
Tri-Hybrid Nanofluid Flow Towards Convectively Heated Stretching Riga Plate with Variable Thickness
Authors: Thakur Archie , Sood Shilpa
Published: January 2023

An advanced tri-hybrid nanofluid model is studied for heat transfer in this current article. Tri-hybrid nanofluids are formed by involving three different types of nanoparticles in the base fluid. In the present study, the heat transfer characteristics of boundary layer flow of Al2O3–Cu–Ni/H2O
tri-hybrid nanofluid have been studied on a convectively heated stretching Riga plate with variable thickness. The relevant governing boundary layer equations are transformed into a set of ordinary differential equations using appropriate similarity transformations which are solved using the
bvp4c program in MATLAB. No previous investigation has been done on the flow of tri-hybrid nanofluid Al2O3–Cu–Ni/H2O past a convectively heated Riga plate of variable thickness to date. Consequently, to fill this gap, the present study has been
taken out and the main aim of this work is to investigate the factors that enhance the heat transfer of base fluid (H2O) suspended with tri-hybrid nanoparticles (Al2O3, Cu, and Ni) past a convectively heated Riga plate with variable thickness. The plots obtained
reveal that the variation in the non-dimensional physical parameters induced in the problem significantly affects the flow inside the boundary layer. The variation in skin friction coefficient and local Nusselt number are presented through graphs. Also, a comparative analysis of velocity and
temperature profiles of nanofluid Al2O3/H2O, hybrid nanofluid Al2O3–Cu/H2O, and tri-hybrid nanofluid Al2O3–Cu-Ni/H2O has been displayed through graphs. The reason behind choosing
the tri-hybrid nanoparticles Al2O3, Cu, and Ni was the stability and non-reactivity of Al2O3 with metals Cu and Ni which possess high thermal conductivity. The conducted study reveals that the heat transfer characteristics of tri-hybrid nanofluids
are greater than that of hybrid and conventional nanofluids.
Heat and Mass Transfer Analysis of Single Walled Carbon Nanotubes-Water and Multi Wall Carbon Nanotubes-Water Based Maxwell Nanofluid Flow Over Stretchable Rotating Disks
Authors: Sudarsana Reddy P. , Sreedevi P.
Published: January 2023

Influence of thermal radiation and magnetic field on heat transfer and flow analysis of water-CNTs type nanofluid between two stretchable revolving disks with heat generation/absorption and convective boundary condition is numerically examined in this analysis. The most extensively
validated Finite element technique is employed to solve the reduced non-linear ordinary differential equations together with boundary conditions. Velocity and temperature distributions are calculated and are displayed through graphs for various values of pertinent parameters entered into the
problem. Furthermore, the values of rates of change of velocity and temperature are examined in detail and are portrayed in tabular form. The values of skin friction co-efficient at both upper and lower disks elevates in the boundary layer regime with rising values of Deborah number in both
nanofluids and this augmentation is higher in MWCNTs-water than SWCNTs-water based Maxwell nanofluid. Temperature of the fluid in both nanofluids deteriorates as the values of nanoparticle volume fraction parameter upsurges and this deterioration in temperature distributions is higher in MWCNTs-water
than the SWCNTs-water based Maxwell nanofluid.

Authors: Umavathi J. C. , Sutkar P. S.
Published: January 2023

An investigation of the micropolar nanofluid sandwiched between permeable fluids enclosed in a horizontal channel is illustrated. The flow is modeled using Tiwari-Das single phase model to interpret the nanofluid and Brinkman model to define the permeable fluid. Closed form solutions
are accomplished in the three regions utilizing the boundary and interface conditions. Graphical results are sketched for the reaction of material parameter, solid volume fraction, porous parameter, Eckert number, nanoparticles and cell rotational viscosity for the linear velocity, microrotation
velocity and temperature. The skin friction, Nusselt number and mass flow rate are also reckoned. Velocity and temperature are down toned with material parameter, solid volume fraction and porous parameter whereas Eckert number develops the temperature. The optimal Nusselt values are obtained
for Graphite oxide when compared with copper, silver and copper oxide nanoparticles.
An Investigation of Entropy and Exergy of Nanofluid Flow in Microchannel Heat Sinks
Authors: Korei Zakaria , Benissaad Smail , Filali Abdelkader , Berrahil Farid
Published: January 2023

The current study aims at performing the thermodynamic analysis of three different scenarios of the heat sinks numerically using the finite volume method (FVM). To this effect, heat sinks are made of aluminium to provide cooling for an electronic chip. In this respect, the three cases
examined throughout this study are as follows: One with one layer and two with two layers flowing in different directions, counter-current, and parallel. The parameter’s analysis of the present investigation consists of three solid volume fractions (Φ) up to 3% for Reynolds
number ratio (Rer) in the range of 0.25 ≤ Rer ≤ 2. Their imprints have been highlighted on frictional, thermal, and global entropy generation, the first law of thermodynamics and exergy efficiency, heat transfer, and pumping power. The findings revealed
that the first law and exergy efficiencies are higher in the single-layered heat sink. However, the effect of solid volume fraction and Reynolds number ratio on these efficiencies is minimal. On the other hand, the double-layered heat sink generates less entropy than the single-layered one,
which may be reduced by raising the Reynolds number ratio and solid volume fraction. Finally, the findings show that the heat transfer is higher in the double-layered heat sink but is accompanied by a considerable rise in pumping power.
Intra-Party Cohesion in Zimbabwe’s Ruling Party after Robert Mugabe
Authors: Zamchiya Phillan
Published: January 2023

Some mainstream political scientists apply the trilogy of exit, voice and loyalty in studying intra-party cohesion. This approach applies more neatly in liberal than in repressive contexts. I therefore make three modifications to enhance the trilogy’s descriptive and explanatory power in an authoritarian context using the ruling Zimbabwe African National Union Patriotic Front (ZANU PF) after Robert Mugabe. First, there is need to integrate non-voluntary exit as party members are mostly expelled against their will in a context where there are limited livelihood opportunities outside party-state patronage and defection is ruthlessly punished. Second, voice should be understood as predominantly expressed over preferences for personalities in internal power distribution rather than over policies. Third, loyalty is not always to the party institution to promote unity but to individuals or factions. From this positioning, ZANU PF is predominantly a non-cohesive party characterised by ephemerally organised leader-follower groups largely seeking power and patronage.
Violence against Scheduled Caste Women: The Case of Rape across States in India
Authors: Chakraborty Chandrima , Pal Soma , Pal Dipyaman
Published: January 2023

The present paper is an endeavour to get in the brutal social practices against scheduled caste (SC) women in India utilizing state-level information over the period of nearly two decades, that is, 2001–2019. Besides law enforcement and punishment, there can be other compelling instruments for controlling rape against SC women. The result proposes interstate disparity in rape rate. Rape against SC women may be controlled with higher economic growth, education and expanding expenditure on police. The DEMARU states are still found slacking behind in controlling rape of SC women.
How Different Types of Linguistic Information Impact Voice Perception: Evidence From the Language-Familiarity Effect
Authors: Yu Keke , Zhou Yacong , Zhang Linjun , Li Li , Li Ping , Wang Ruiming
Published: January 2023

Previous studies have suggested the effect of linguistic information on voice perception (e.g., the language-familiarity effect [LFE]). However, it remains unclear which type of specific information in speech contributes to voice perception, including acoustic, phonological, lexical, and semantic information. It is also underexamined whether the roles of these different types of information are modulated by the experimental paradigm (speaker discrimination vs. speaker identification). In this study, we conducted two experiments to investigate these issues regarding LFEs. Experiment 1 examined the roles of acoustic and phonological information in speaker discrimination and identification with forward and time-reversed Mandarin and Indonesian sentences. Experiment 2 further identified the roles of phonological, lexical, and semantic information with forward, word-scrambled, and reconstructed (consisting of pseudo-Mandarin words) Mandarin and forward Indonesian sentences. For Mandarin-only participants, in Experiment 1, speaker discrimination was more accurate for forward than reversed sentences, but there was no LFE in either sentence. Speaker identification was also more accurate for forward than reversed sentences, whereas there was an LFE for forward sentences. In Experiment 2, speaker discrimination was better for word-scrambled than reconstructed Mandarin sentences. Speaker identification was more accurate for forward and word-scrambled Mandarin sentences but less accurate for Mandarin reconstructed and forward Indonesian sentences. In general, the pattern of the results for Indonesian learners was the same as that for Mandarin-only speakers. These results suggest that different kinds of information support speaker discrimination and identification in native and unfamiliar languages. The LFE in speaker identification depends on both phonological and lexical information.

Does Social Globalization Affect the Relationship Between International Tourism and Economic Growth?
Authors: Haini Hazwan , Wei Loon Pang , Yong Soo Keong , Husseini Sufrizul
Published: January 2023

This study examines the moderating effect of social globalization on the relationship between international tourism and economic growth using a dataset of 143 economies from 1995 to 2017. Social globalization is broadly defined as the sharing of cultures and beliefs which facilitates the flow of ideas and knowledge. Our results show that social globalization affects economic growth directly and indirectly through enhancing international tourism. However, we find that the direct effect of international tourism on growth is not statistically significant for developing economies. On the other hand, tourism-dependent developing economies can benefit from growth as social globalization increases. This implies that policymakers can promote growth by developing institutions and infrastructure to enhance social globalization, such as implementing visa-free travel and the construction of international airports, to enhance the growth-gains from international tourism.
The Validity of the ODARA in Australian Intimate Partner Violence Cases Without Prior Assault/Credible Threat or Cohabitation
Authors: Mcewan Troy E. , Pichler Anne Sophie , Ogloff James R. P. , Simmons Melanie
Published: January 2023

This study investigated whether the Ontario Domestic Assault Risk Assessment (ODARA) is effective in the assessment of risk in male intimate partner violence (IPV) cases that do not meet the inclusion criteria used in the ODARA’s development sample (presence of prior assault or threat by perpetrator and previous cohabitation with the victim). Australian police scored the ODARA in 275 IPV cases without one or both of these characteristics, with results contrasted to performance in 200 cases meeting both inclusion criteria. The ODARA demonstrated poor discriminant effect over time for both assault and abuse recurrence in the former group (concordance index [c-index] = 0.56 and c-index = 0.57, respectively), but performed well in the latter group (c-index = 0.69 and c-index = 0.69). Although subject to some significant methodological limitations and requiring replication, these findings suggest the ODARA may not provide accurate risk-based classification if applied to cases missing the inclusion criteria.
Intraoperative brainstem auditory evoked potential monitoring during cerebellopontine angle surgery via retrosigmoid approach
Authors: Zhang Yi , Zhou Enhui , Xue Xiaocheng , Chen Xiaoping
Published: January 2023

Objectives

Brainstem auditory evoked potential (BAEP) monitoring was used to identify the influence of auditory function during cerebellopontine angle (CPA) surgery for cranial neuropathy via the retrosigmoid approach.

Methods

This prospective study included 20 patients who underwent CPA surgery for cranial neuropathy via the retrosigmoid approach with intraoperative BAEP monitoring and pure tone audiometry (PTA). The latency and interpeak latency were analyzed at each surgical step in combination with the pre- and postoperative PTA.

Results

Follow-up data were available for 17 patients. The mean pre- and postoperative PTA values were 25.65 dB and 20.70 dB, respectively. Two patients (2/17, 11.76%) developed hearing loss postoperatively. The latency of wave І significantly changed during direct auditory nerve manipulation and at the end of the surgery, while that of wave III only changed during direct auditory nerve manipulation. The appearance of wave V peak was delayed during CPA surgery.

Conclusions

CPA surgery for cranial neuropathy via the retrosigmoid approach can cause hearing loss to varying degrees, and intraoperative BAEP monitoring can reduce the occurrence of hearing loss. Intraoperative hearing function can be estimated by the latency of wave I. Hearing loss due to stretching of the brainstem can be estimated by the latency of wave III, and wave V is an early indicator of intraoperative hearing loss. Waves I and III remained stable both pre- and postoperatively, whereas wave V was unstable despite no surgery. Therefore, a precise operation and well-defined operative steps for surgeons during CPA surgery could facilitate maximal preservation of the anatomical structure and function.
Is Men’s Heterosexuality Perceived as More Precarious Than Women’s? An Intersectional, Race-by-Gender Analysis
Authors: Petsko Christopher D. , Vogler Stefan
Published: January 2023

People perceive men’s masculinity to be more precarious, or easier to lose, than women’s femininity. In the present article, we investigated (a) whether men’s heterosexuality is likewise perceived to be more precarious than women’s, and if so, (b) whether this effect is exaggerated when the targets in question are Black rather than White. To investigate these questions, we conducted three experiments (one of which was conducted on a probability-based sample of U.S. adults; total N = 3,811) in which participants read about a target person who either did or did not engage in a single same-sex sexual behavior. Results revealed that participants questioned the heterosexuality of men more than the heterosexuality of women when they engaged (vs. did not engage) in same-sex sexual behavior. Surprisingly, these effects were not moderated by whether targets were Black versus White. Results are interpreted in light of recent models of intersectional stereotyping.
Self-esteem and competition
Authors: Gilabert Pablo
Published: January 2023

This paper explores the relations between self-esteem and competition. Self-esteem is a very important good and competition is a widespread phenomenon. They are commonly linked, as people often seek self-esteem through success in competition. Although competition in fact generates valuable consequences and can to some extent foster self-esteem, empirical research suggests that competition has a strong tendency to undermine self-esteem. To be sure, competition is not the source of all problematic deficits in self-esteem, and it can arise for, or undercut goods other than self-esteem. But the relation between competition and access to self-esteem is still significant, and it is worth asking how we might foster a desirable distribution of the latter in the face of difficulties created by the former. That is the question addressed in this paper. The approach I propose neither recommends self-denial nor the uncritical celebration of the rat race. It charts instead a solidaristic path to support the social conditions of the self-esteem of each individual. The paper proceeds as follows. I start, in section 2, by clarifying key concepts involved in the discussion. In section 3, I identify ten mechanisms that support individuals’ self-esteem and impose limits on competition. I focus, in particular, on the challenges faced by people in their practices of work. In section 4, I outline prudential and moral arguments to justify the use of the proposed mechanisms. Section 5 concludes with remarks on the role of social criticism in the processes of change implementing the mechanisms.
Michel Serres and the Philosophy of Technology
Authors: Barker Timothy
Published: January 2023

This article explores the topic of technology in Michel Serres’ work. Although a great deal has been said about Serres’ treatment of parasitic relations, noise, interdisciplinarity and communication, little has been written about his approach to questions of technology. The author first outlines general trends in the philosophy of technology and indicates how Serres fits within the field. He then suggests a way to read Serres by identifying ‘landmarks’ in his texts, which are used for explicating his position on technology. Three of these landmarks are explored. The first is Serres’ philosophy of world-objects, which moves him to think through the relationship between humans, technology and natural evolution. The second is Serres’ notion of technologies ‘setting sail’ from the body, which allows him to build on Leroi-Gourhan’s work, and the third is Serres’ description of information technologies and the world of millennials, which leads to his position on pedagogy and technology. From an examination of these three landmarks, a picture emerges of a thinker for whom technology acts as a disturbance around which collectives form, establishing relations and deviations between ourselves and others.

Unpaved roads have different characteristics to paved roads. A key way of investigating potential risk factors is to analyze traffic crashes that have occurred on unpaved roads. The objective of this study was to estimate the influence of different factors on crash occurrence on unpaved roads. Five years (2016–2020) of traffic crash data from Kansas were collected and analyzed by applying binary logistic regression. Results showed that 23 factors were statistically significant among the 25 factors analyzed, which were categorized according to driver, road, and crash characteristics. Factors resulting in a higher likelihood of occurrence included the presence of farm equipment, the vicinity of yards and fields, and railroad crossings. Several factors were found to result in a low likelihood of occurrence, for example, roads with more than two lanes, interchanges, ramps, existence of a median, and low volume of traffic. However, widening the road may not guarantee crash reduction on unpaved roads. An effective step to reduce the likelihood of crashes could be proper educational programs targeting teen drivers to make them aware of the dangers of driving on unpaved roads. It is also recommended that traffic control devices should be situated at railroad crossings and locations with nearby access to farms and agricultural land. In addition, a further study could be conducted to estimate the site-specific road width and speed limits.

In 2017 four test sections (test sections 133, 233, 135, and 235) containing a cold central-plant recycled (CCPR) layer underneath a surface treatment were constructed on the MnROAD low-volume road (LVR). Two types of CCPR mix designs were constructed: test sections 133 and 235 contained an emulsified asphalt; test sections 135 and 233 contained a foamed asphalt. Each CCPR mix design (foamed asphalt and emulsified asphalt) had two types of wearing surface layers (double chip seal and 1.5 in. HMA [hot-mix asphalt] overlay—thinlay) to create the four test sections. The rest of the pavement structure beneath the newly constructed CCPR was left in place and consistent throughout all four test sections with the remaining granular base over the existing clay subgrade. This paper presents a revisiting of the field performance of the CCPR test sections at the MnROAD LVR. To do this extensive field data was collected over approximately 3 years through visual distress surveys, and ride quality, rutting, and falling-weight deflectometer testing. Field study determined that both CCPR mix designs (foam and emulsion) performed similarly and the thinlay HMA layer outperformed the double chip seal in respect of rutting; but both surfaces are considered valid alternatives for future applications depending on the traffic volumes expected.

In this study, we aimed to determine whether paid work has an impact on health-related quality of life (HRQOL) among older adults. Over three years, we longitudinally collected data from 5,260 community-dwelling older adults aged 75 years or older from a city in Japan. We assessed HRQOL using the Short-Form-8. We estimated the mean difference between the physical component summary (PCS) and the mental component summary (MCS) scores, which were stratified based on gender using multivariate, generalized estimating equation models. We further conducted a subgroup analysis based on the participants’ occupational backgrounds. Engagement in paid work was associated with increased MCS scores across both genders and with increased PCS scores among women. In the subgroup analysis, only women who had previously worked as managerial workers showed an inverse association with MCS scores. In this population, engagement in paid work may be a crucial factor associated with well-being.
Validation and Psychometric Properties of the Turkish Version of the Riverside Eudaimonia Scale

The Riverside Eudaimonia Scale (RES) has been recently developed to measure psychological measures of eudaimonia. Currently, there is no evidence regarding its psychometric properties in Turkish. Therefore, this study, for the first time, examined the validation and psychometric properties of the Turkish version of the RES. Participants included 336 undergraduate students from a public university in Turkey. The results showed good internal consistency of the RES suggesting a good measure to assess eudaimonic flourishing. Exploratory and confirmatory factor analyses yielded a one-factor structure as a good fit with strong reliability evidence. The results indicated that the RES was correlated with life satisfaction and flourishing, and the RES explained a significant amount of variance in the prediction of life satisfaction and flourishing after controlling for age and gender. The results suggest that the RES has sound psychometric properties, is culturally and linguistically acceptable, and is equally fruitful in measuring eudaimonic flourishing in Turkish population.

Adolescents’ conflict between circadian rhythm and early school start time is more pronounced in evening chronotypes, who tend to reduce sleep duration during school days compensating during the free days by oversleeping (i.e., social jetlag). Cumulative weekly sleep debt may impair sport performance, which relies on physical and cognitive skills modulated by sleep. We hypothesized that chronotype predicts sport performance, and that it may interact with the day of the week. Moreover, given the role sleep plays in motor memory consolidation, we tested the hypothesis that school attendance, and the related chronic sleep deprivation, might be detrimental for participants in a training phase. Ninety-three adolescent male basketball players performed multiple free throw sessions ( n = 7880) during both the school and holiday periods. Chronotype and its interaction with the day of the week significantly predicted shooting accuracy when attending school, but not on holidays. Evening types’ performance gradually decreased from Monday to Friday. Participants with a more unstable performance (i.e., who did not complete the acquisition of the free throw motor scheme) worsened their accuracy when attending school. Our results suggest that the impact of chronotype and day of the week on sport performance is related to the presence of an externally imposed sleep/wake schedule and is consistent with evening types’ increased likelihood of experiencing social jetlag. Possibly due to early school start time, attending school worsened the performance of participants in a training phase. Further investigations are required to assess whether reducing the mismatch between biological and social clocks might improve sport performance, along with other aspects of adolescents’ life.
Examining Heterogeneous Configurations of Socioemotional Wealth in Family Firms Through the Formalization of Corporate Social Responsibility Strategy

Published: January 2023

Family firms purportedly use different socioemotional wealth (SEW) reference points in choosing strategies, yet empirical research continues to use family involvement as a proxy for SEW. This study uses a configurational approach to examine how the multidimensionality of SEW may be used to explain the firm’s chosen strategy. We use psychometric measures of the various SEW dimensions proposed by Berrone et al. to explain the formalization of corporate social responsibility (CSR) strategy as an example. We identify various SEW configurations to understand why family firms exhibit a preference for more formal or informal CSR strategies.

This study investigates the microscopic morphology of a hydraulic servo spool valve caused by particle erosion. The microscopic morphology of spool working edges and solid particle characteristics in oil of a typical hydraulic servo system were experimentally studied. The formation mechanism was analyzed using dynamic impact calculation. The results reveal that the erosion micro-morphology of the spool working edge was mainly characterized by surface peeling, notches, grooves, and chamfers. The contour of the working edge was rounded. The average and variance of the radius of the old spool’s working edges were obviously higher than those of the new spool. The main distribution range of solid particle size in typical servo-hydraulic system oil was 5–50 μm, and the number of particles decreased sharply with an increase in particle size, up to 90.89%. The actual shape of particles was close to an ellipsoid with strong erosion destructive power. When a single solid particle collided with the working edge, a large amount of stress was generated at the collision center point, and the stress can reach 1500 MPa when the pressure differential at the valve orifice was 3.5 MPa. The working edges were subjected to cyclic stress of high-frequency particle pulses, resulting in fatigue erosion.
