Published: October 2022

Background. Jujuboside B (JUB) is a saponins isolated from the seeds of Zizyphi jujuba var. spinosi, which is used to treat mental illness and is reported recently to induce cancer cell apoptosis. As our previous research showed chronic stress promoted tumor growth, this work aims to investigate whether JUB exert antitumor effect in addition to its antidepressant effect and possible mechanism. Methods. 56 female C57BL/6 mice were grouped into 7 groups: A (blank control), B (tumor-bearing control), C (tumor-bearing + JUB), D (CUMS control), E (CUMS + JUB), F (tumor-bearing + CUMS), and G (tumor-bearing + CUMS + JUB). Groups C, E, G, B, D, and F were administered, respectively, with JUB (40 mg/kg/day) or vehicle for 2 weeks. Serum 5-HT, Trp (tryptophane), inflammatory cytokines TNF-α, IL-4, -6, and -10 levels were detected by ELISA. The tumors in groups B and F were isolated for RNA-seq sequencing. Protein and mRNA expression of Bax, Bcl-2, p-PI3K, p-Akt, p-MAPK, p-ERK, and p-CREB in tumor tissues were detected. In vitro, A549 cells were stimulated with JUB (60 μmol/L), in which proliferation rate and colony formation rate were detected. The PI3K/Akt and, MAPK/ERK pathway were measured. Results. Chronic stress successfully induced the depression-like phenotype (group D vs. A) and promoted tumor growth (group B vs. F). JUB significantly ameliorated the depression-like phenotype and increased 5-HT, Trp levels (group D vs. E), and reversing CUMS-induced tumor progression. Meanwhile, JUB decreased inflammatory cytokine levels. Chronic stress upregulated the phosphorylation levels of PI3K/Akt/MAPK/ERK/CREB; JUB reversed this regulation. JUB significantly inhibited cell viability, colony formation rate, and downregulated the phosphorylation levels of PI3K/Akt/MAPK/ERK/CREB in vitro. Conclusions. JUB reverses CUMS-promoted tumor progression in tumor-bearing mice with depression-like phenotype. JUB exerts the dual beneficial effect on tumor growth and depression-like phenotype by blocking the signal transduction pathway of PI3K/Akt, MAPK/ERK, and dephosphorylating the downstream signaling regulator CREB.

Published: October 2022

In order to meet the personalized needs of different students and provide students with a variety of intelligent learning strategies and learning content, this research is aimed at the current lack of intelligent function design in the network teaching platform of colleges and universities. Based on the concept of integration of production and education, with the help of intelligent recommendation algorithm of reinforcement learning, a personalized learning platform based on intelligent algorithm is constructed. First, through the method of questionnaire survey to understand the students’ needs for personalized learning and the functions of online teaching platform, on this basis, build a personalized learning platform based on reinforcement learning and data mining intelligent algorithm. The system test results show that when the number of accesses is less than 2000, the CPU and memory resources of the system basically remain unchanged. When the number of accesses is less than 3000, the CPU utilization rate reaches 70%, and the performance decreases, but it can also ensure normal operation.
Lipase and Its Unique Selectivity: A Mini-Review
Authors: Park Jun-Young , Park Kyung-Min
Published: October 2022

Contrary to other solid catalysts, enzymes facilitate more sophisticated chemical reactions because most enzymes specifically interact with substrates and release selective products. Lipases (triacylglycerol hydrolase, EC 3.1.1.3), which can catalyze the cleavage and formation of various acyl compounds, are one of the best examples of enzymes with a unique substrate selectivity. There are already several commercialized lipases that have become important tools for various lipid-related studies, although there is still a need to discover novel lipases with unique substrate selectivity to facilitate more innovative reactions in human applications such as household care, cosmetics, foods, and pharmaceuticals. In this mini-review, we focus on concisely demonstrating not only the general information of lipases but also their substate selectivities: typoselectivity, regioselectivity, and stereoselectivity. We highlight the essential studies on selective lipases in terms of enzymology. Furthermore, we introduce several examples of analysis methodology and experimental requirements to determine each selectivity of lipases. This work would stress the importance of integrating our understanding of lipase chemistry to make further advances in the relevant fields.

Authors: Wei Xuejiang , Wu Libing
Published: October 2022

This paper is a comparative study on the performance of the fog-enabled sensor cloud (FSC) and traditional cloud computing and fog computing modes in a smart logistics park. Based on our previous work, we describe the physical sensor virtualization scheme and framework of the proposed FSC, construct the network model, and mathematically describe the parameters of the FSC. To assess the performance of the proposed platform, we take a large logistics enterprise in China as an example and illustrate the network setup of the proposed platform in a real logistics scenario. The experiment proves that the FSC for smart logistics parks has a practical advantage over the traditional cloud computing and fog computing modes in terms of bandwidth consumption and service latency.
Synergistically Improving Mechanical and Interfacial Properties of Epoxy Resin and CFRP Composites by Introducing Graphene Oxide
Authors: Cao Lijuan , Zhi Jieying , Yang Yu , Yuan Liye , Song Yingjun , Lu Xiaoxuan , Lu Chunxiang
Published: October 2022

In this study, graphene oxide (GO) was employed as nanoscale reinforcement for the development of high-performance carbon fiber reinforced plastic (CFRP) composites. Initially, epoxy resin was modified by incorporating GO with different weight proportion from 0.05 to 0.6 wt.%. Then the unidirectional CFRP composites were prepared with the modified epoxy resin by winding and compression molding technique. The optimized GO-CFRP composites with GO content of 0.1 wt.% present tensile strength of 2756 MPa and monofilament interfacial shear strength of 29.06 MPa, respectively, which are 14.4% and 12.5% higher than the corresponding values of the pristine CFRP composites. To intuitively observe the fracture process of the CFRP composites, the digital image correlation system was employed. It is verified that the moderate addition of GO can improve the stress concentration of the CFRP composites during the deformation process. In addition, the reinforcing mechanism is investigated by analyzing the fracture surface of the modified epoxy resin and the CFRP composites. The results indicate that GO can make the cracks deflect or bifurcate along with the epoxy resin which closes to graphene, resulting in synergistically improved mechanical and interfacial properties of the GO-modified CFRP composites.

Published: October 2022

Steel pipe columns are an important component in subway station construction and with stand stress state and internal force during the construction process. Based on the engineering background of Beijing subway, this paper introduces the geological conditions, station structure types, and internal force monitoring of steel pipe columns of 10 subway stations constructed by the PBA method. The field monitoring indicates that the greatest change in the internal force of the steel pipe column occurs during stage 1 (beam, primary support, and secondary lining buckle arch construction stage), no matter pile foundation station or strip foundation station, which accounts for about 60% to 65% of the total axial force. When the left and right spans are not synchronously arched or excavated, the steel pipe column is subjected to uneven forces and bears a large bending moment is produced. When the depth of overburden is between 7 m and 15 m, the internal force of the steel pipe changes positively correlated with the overburden depth. During the construction process, the internal force of the steel pipe varies widely in the silty sand stratum. Also, the steel pipe columns in stations affected by groundwater bears about twice of the axial force compared with other stations are not affected by groundwater. In addition, the construction period is also a factor that affects changes in internal forces. This research is conducive to update the database of the world subway projects and can serve as a practical reference for similar geological condition.

Authors: Yu Ning
Published: October 2022

Martial arts routines originated in China and are a traditional sport of the Chinese nation. They are one of the outstanding sports culture representatives in China since ancient times. Excessively difficult movements in some martial arts routines during competitions or training can cause athlete injuries. The purpose of this article is to study the effect of proprioceptive training of ankle joints on preventing ankle injuries in martial arts athletes. Can ankle strength training and ankle proprioceptive training combined with strength training improve the dynamic and static balance of football players? This article analyzes the mechanism and causes of martial arts athletes’ injuries and proposes treatment methods for ankle injuries. In the experimental part of this article, 16 martial arts athletes (8 males and 8 females) were selected as research objects, and they were randomly divided into 4 male and female experimental groups and 4 control groups. The experimental group received ankle muscle strength training for 6 weeks, and the control group received ankle muscle strength training and ankle proprioception training. The experimental results prove that ankle proprioceptive training can improve the dynamic and static balance of martial arts athletes and can effectively prevent the occurrence of ankle injury. In this paper, the dynamic balance ability in the biped standing state with eyes closed was tested, and the reductions of the stability index in the front and back directions of the control group and the experimental group were 0.03 and 0.2, respectively. It can be seen that the stability training effect of the experimental group was obvious.

Authors: Shen Xiuqin , Wei Jiao , Zhang Ying , Zhang Yinying
Published: October 2022

Objective. The infusion room is the last part of an outpatient visit, with high patient density, large staff mobility, and a wide variety of conditions. In addition, most patients are accompanied by their families during infusion, and nursing staff in infusion rooms have to face more trivial and miscellaneous tasks than nursing staff in other treatment departments, which are more complex. The purpose of this research is to explore the impact of the Six Sigma method and CI strategy on the quality of nursing management in infusion rooms, so as to provide reference for clinical research. Methods. A total of 2142 patients treated in our outpatient infusion rooms from June 2019 to June 2020 was included into this retrospective analysis. Of these, 1105 patients admitted before 2020 received routine care management services and were considered as the control group. Another 1037 patients were admitted after 2020 and received the Six Sigma method combined with CI strategic care management and were considered as the research group. The incidence of adverse events during treatment was counted in both groups, and patients’ compliance behavior and psychology were investigated. After treatment, patients’ evaluation of the quality of nursing and their satisfaction with the nursing were investigated. Results. The incidence of adverse events during infusion in the research group was dramatically lower than that in the control group, while the compliance behavior scores were higher (P < 0.05). In addition, SAS and SDS in the research group were lower than those in the control group, while the quality of nursing were higher (P < 0.05). It was also clear that the research group had 93.39% satisfaction with nursing, which was also higher than the control group (P < 0.05). Conclusion. Implementation of infusion room nursing management according to the Six Sigma method with CI strategic plan can avoid adverse events and improve infusion nursing satisfaction. It also helps reduce the incidence of dispute events.

Authors: Laouar Zineb , Arar Nouria , Ben Makhlouf Abdellatif
Published: October 2022

In this study, an accurate and efficient numerical method based on spectral collocation is presented to solve integral equations and integrodifferential equations ofn-th order. The method is developed using compact combinations of shifted Legendre polynomials as a spectral basis and shifted Legendre–Gauss–Lobatto nodes as collocation points to construct the appropriate algorithm that makes simple systems easy to solve. The technique treats both types of equations: linear and nonlinear equations. The study aims to provide the relevant spectral basis by the use of compact combinations, which allows us to take advantage of shifted Legendre polynomials and to reduce the dimension of the space of approximation. The reliability of the proposed algorithms is proven via different examples of several cases and the results are discussed to confirm the effectiveness of the spectral approach.

Published: October 2022

Solar energy has become an integral part of the economy of developed countries, so it is important to monitor the pace of its development, prospects, as well as the largest companies that produce solar panels since the supply of solar energy in a particular country directly depends on them. The study analyzes the shares of Canadian Solar Inc. and First Solar Inc. The purpose of the study is to study the possibility of forecasting the stock price of solar energy companies using neural networks for the purpose of subsequent investment. The recurrent neural network LSTM is used in the article and this approach is based on complexity theory. Machine learning technologies are now being actively implemented in various sectors of the economy and are considered effective. The program used assigns different significance to the data of the last months and the data for the first months of the 1st year. The first year of the last 5 years of the company’s activity is taken as the first year since more distant data no longer have significant significance for the forecast. In the course of the study, a forecast of the stock price of Canadian Solar Inc. and First Solar Inc. for 245 days was obtained. Based on the results obtained, the following conclusions were made: 20 neurons of the network is not enough to make an accurate forecast, but the level of confidence in such a forecast is high enough, neural network forecasts are applicable in investing and are accurate enough to determine medium‐ and long‐term trends, but these forecasts are not applicable for traders. The direction of improving the accuracy of neural network predictions is promising for further research.

Authors: Hou Guoliang
Published: October 2022

The creation of a deep neural network model with numerous hidden layers enables the layer‐by‐layer extraction of features from the input high‐dimensional data, enabling the identification of the data’s low‐dimensional nested structure and the development of a more efficient and abstract high‐level representation. The research on deep learning is thoroughly examined, along with the direction it needs to take going forward. Supporting the construction of new socialist rural areas as a calculated move to address the problems facing farming, rural communities, and farmers is another essential step in furthering modernization. It helps to reshape the entire rural landscape, coordinate the growth of urban and rural areas, achieve the goal of a wealthy society in every way, boost demand, and support the holistic development of people. The emergence of new socialist rural communities against the background of deep learning is the subject of significant research and analysis in this work. In the research, it is examined and studied using deep learning methods and convolutional neural networks. It is evident from the research described in this paper that deep learning backgrounds have a considerable impact on the development of new rural areas—up to 54.53%. In this essay, the foundation for the future construction of a new socialist countryside is laid forth.

Authors: KONYA Sevilay , ŞAKALAK Ayşenur , KARAÇOR Zeynep
Published: October 2022

Research & development expenditures, which are innovative and creative work, are evaluated as an substantial factor in productivity, competitiveness, and sustainable growth performance in developed countries. This study, is targeted to empirically analyze the impact of research & development expenditures on economic growth and unemployment in 25 selected countries from the years 1996-2020. Panel data analysis was carried out with methods that take into account the cross-section dependency. After testing the unit root of the variables in the econometric model, the Westerlund cointegration test was used to determine the long-run relationship. Afterward, short and long-term coefficients were determined with panel ARDL data methods. The empirical findings revealed that there is an interaction between research & development expenditures and economic growth in the short and long run. However, while a relation was determined between research & development expenditures and employment in the short run, no relationship was found between the two variables in the long term. Dumitrescu and Hurlin's causality analysis was performed to determine the causal relation and a causal link between research & development expenditures and economic growth and between research & development expenditures and employment was determined.
EMIGRATION AND ECONOMIC GROWTH IN EUROPEAN TRANSITION ECONOMIES: EVIDENCE FROM A BOOTSTRAP PANEL CAUSALITY TEST IN ROLLING WINDOWS
Authors: RECEPOĞLU Mürşit
Published: October 2022

The relationship between migration and economic growth has long been a matter of discussion in theoretical and empirical domains. Previous studies which explored the link between variables suggested an estimation for an unchanging parameter. Despite that; prevailing economic and political circumstances, effective contracts and agreements, implemented policies, ongoing crises or shocks can cause a shift in the relationship across variables in due course. This study analyses the relationship between emigration and economic growth in transition economies in Europe for the period between 1995-2019 by administering time-varying causality test. Findings obtained from the bootstrap panel causality test suggest that there is a bidirectional causality relationship between emigration and economic growth only in Estonia but results of bootstrap panel rolling window causality analysis reveal that for the subperiods, there exist hidden causal relationships within Hungary, Lithuania, Poland, Slovakia and Slovenia.
Barriers to inclusion embedded in the Disability Discrimination Act 1992 (Cth)
Authors: Dickson Elizabeth
Published: October 2022

The Disability Discrimination Act 1992 (Cth) (DDA) prohibits discrimination by schools against students with disability. The DDA and the associated Disability Standards for Education 2005 (Cth) (DSE) also impose a positive obligation on schools to make reasonable adjustment for students with disabilities. The promise of inclusion implicit in these laws, however, has not always been delivered upon, as there are still opportunities for schools to exclude students with disabilities, without breaching the laws. This article provides an overview of relevant provisions of the DDA and DSE, before considering the legal barriers to inclusion which have been constructed by courts through their interpretation of the DDA.
Reservations for Other Backward Classes in Jammu and Kashmir: An Impact Assessment
Authors: Dabgotra Pankaj , Gupta Bhawna
Published: October 2022

Reservation is a system of affirmative action that provides historically disadvantaged groups representation in education, employment and politics in India. This research article assesses the impact of reservations on the economic and educational condition of Other Backward Classes (OBCs) in Jammu and Kashmir (J&K). The Jammu and Kashmir Reservation Act, 2004 1 provided for the reservations in appointments, and admissions in professional institutions to socially and educationally backward classes of the State. The theoretical framework and historical underpinnings of reservations in India have been examined based on secondary data and a survey of OBC beneficiaries (through purposive sampling) in the Jammu district done to assess the impact on the target groups. The authors find that the present approach to reservations has shown dismal improvement in the economic and educational lots of the OBCs in J&K. There is a need for a rational criterion for identifying the beneficiaries and proportionate quantum of reservations. A holistic and integrated approach for addressing lacunas in policy will help bring the required change.

Authors: Feng Xiaoliang , Zhao Guang , Wang Yi , Gao Dijun , Ding Han
Published: October 2022

In order to make full use of the absolute position information of fault signal, this paper designs a new multi-head attention (MHA) mechanism focusing on data positional information, proposes a novel MHA-based fault diagnosis method and extends it to the fault diagnosis scenario with missing information. Based on the absolute positional information and the trainable parameter matrix of the fault data, a novel attention weight matrix is generated, and the fault features are extracted by a fully connected network with the attention mechanism. By integrating the positional information into the weight matrix, the new MHA mechanism has the ability to extract more effective data features, compared with the traditional MHA method. Furthermore, the proposed method is also developed for the fault diagnosis scenarios with missing information. A special attention weight modified method is designed to reduce the impact of missing data on fault diagnosis results. In the experiment simulations, the data sampled from ZHS-2 multi-function motor flexible rotor test bed and the Tennessee- Eastman process data are utilized to test the performance of the algorithm. The results show that the proposed method can effectively extract fault features and reduce the impact of missing data.
An analytical investigation of self-temperature-compensated stretchable piezoresistive nanocomposites containing hybrid carbon black/carbon nanotube nanofillers
Authors: Haghgoo Mojtaba , Ansari Reza , Hassanzadeh-Aghdam Mohammad K , Nankali Mohammad
Published: October 2022

In this study, the temperature-dependent piezoresistivity of hybrid carbon black (CB)/carbon nanotube (CNT) nanocomposites is studied using a percolation model with a Monte Carlo simulation approach. With this approach, the temperature-dependency of electrical resistivity and the strain sensitivity of the nanocomposite are investigated. In addition, other parameters such as the aspect ratio, dispersion state and dimensions’ effect on piezoresistivity of the compensated stretchable nanocomposite are investigated. By developing a temperature-dependent percolation model, the temperature sensitivity response of nanocomposite is investigated based on defining the temperature coefficient of resistance of CNT and thermal expansion coefficient of polymer. It is found that the dimensional aspects and dispersion state affected the percolation threshold and resistivity. The obtained results also indicated that the piezoresistivity increased with the decrease in the Poisson’s ratio and intrinsic electrical conductivity. Moreover, the predicted results showed high prediction accuracy for temperature-dependence resistivity compared with the existing experimental data.
Does the Bomb Really Embolden? Revisiting the Statistical Evidence for the Nuclear Emboldenment Thesis
Authors: Suh Kyungwon
Published: October 2022

This paper revisits the latest statistical evidence for the nuclear emboldenment thesis—nuclear-armed states are more likely to initiate military aggression than non-nuclear states—from ( Bell and Miller 2015 ). If correct, their findings have important theoretical and policy implications regarding the effect of nuclear proliferation on international conflict. This paper shows, however, that Bell and Miller’s findings heavily rely on two important components of their statistical analysis: (1) using all state dyad observations, and (2) employing pooled regression models to analyze time-series-cross-sectional (TSCS) data. I argue that those components are based on questionable assumptions on heterogeneity in their dataset. Based on alternative strategies dealing with heterogeneity in dyadic data, my reanalysis shows that the emboldening effect of nuclear weapons is not as robust as originally claimed. Instead, I find the robust deterrent effect of nuclear weapons: nuclear-armed states are less likely to be targeted in military disputes. These findings highlight the need for careful application of quantitative methods to produce a more robust understanding of nuclear issues.
Recovery Identity and Psychosocial-Spiritual Health: A Survey of Individuals in Remission From Substance Use Disorders
Authors: Witte Tricia , Amick Matthew , Smith Jesse
Published: October 2022

Recovery identity – the degree to which someone identifies as “in recovery” from a substance use disorder – has been shown to be associated with a host of positive health outcomes. The purpose of the present study was to test the association between recovery identity, quality of life, spiritual well-being, and relational health in a sample of individuals in remission from moderate or severe SUDs recruited from Amazon’s Mechanical Turk crowdsourcing platform ( n = 494). Results indicated that the presence of a recovery identity was significantly associated with greater spiritual health, but not significantly associated with psychological, social, or environmental quality of life, nor with family functioning. Results have important implications for understanding paths to recovery and important correlates of health outcomes.
Innovation Potential, Insider Sales, and IPO Performance: How Firms Can Mitigate the Negative Effect of Insider Selling
Authors: Cao Zixia , Song Reo , Sorescu Alina , Chua Ansley
Published: October 2022

At the time of an initial public offering (IPO), firms seek to maximize their stock market value. The authors theorize and show that a firm's innovation potential—firm outputs and activities that contribute to the development of future new products—can be used by the managers of IPO firms as a credible signal of the quality of the firm. Using a sample of 370 IPO firms from the consumer-packaged goods and pharmaceutical industries, and three metrics of innovation potential, the authors show that firms’ innovation potential is (1) positively associated with the initial value of the IPO and with the first-day IPO returns and (2) negatively associated with the extent to which insiders sell their shares at the time of the IPO. The effectiveness of the three metrics of innovation potential as a signal of firm quality varies: patents have a stronger impact on insider sales than preannouncements and generic references to future innovation, while preannouncements have the strongest impact on first-day IPO returns. The article presents a nuanced view of the extent to which various firm stakeholders consider information about firms’ innovation potential to be a credible signal that reduces the adverse selection present in IPO deals with insider sales.

Authors: Tureluren Emilie , Claes Laurence , Andriessen Karl
Published: October 2022

Experiencing the death of a loved one increases the risk of developing mental health problems. Students are vulnerable to developing mental health problems, to which substance use can contribute. Still, few studies have examined substance use in bereaved students. Using an online survey, we collected data about the impact of the death of a loved one on Belgian students’ ( N = 666 ) substance use. Using regression analysis we examined its relation to social support, grief, mental health and personal growth. A significant number of students indicated that the death affected their substance use. Feelings of grief and mental health distress played a significant role in students whose substance use increased after the death. There was no significant relationship between social support and personal growth and substance use. Our findings indicate that mental health professionals must address substance use when working with bereaved students to ensure early intervention and adequate support.
Evaluating Optimism, Hope, Resilience, Coping Flexibility, Secure Attachment, and PERMA as a Well-Being Model for College Life Adjustment of Student Veterans: A Hierarchical Regression Analysis
Authors: Umucu Emre , Chan Fong , Phillips Brian , Tansey Timothy , Berven Norman , Hoyt William
Published: October 2022

The purpose of this study is to examine (a) to what extent demographic covariates, foundational and emerging positive psychology traits (FEPPTs), and PERMA uniquely predict college life adjustment, health-related quality of life (HRQOL), and life satisfaction of student military veterans; (b) PERMA as a happiness and well-being model for college life adjustment, HRQOL, and life satisfaction among student veterans; and (c) FEPPTs as predictors of PERMA (positive emotion, engagement, relationships, meaning, and accomplishment). In addition, we tested whether total PERMA scores mediate the relationship between service-connected disability and college adjustment. A total of 205 student veterans responded to an online survey. Results revealed that demographic covariates (e.g., service-connected disability), FEPPTs (e.g., optimism), and PERMA (e.g., positive emotion) significantly accounted for college life adjustment, HRQOL, and life satisfaction of student veterans. In addition, a mediation analysis revealed that PERMA partially mediated the relationship between service-connected disability and college life adjustment of student veterans. The results of this study provide empirical supports for the use of PERMA as a comprehensive well-being model of college life adjustment for student veterans.
The Sociology of Utopia, Modern Temporality and Black Visions of Liberation
Authors: Davidson Joe PL
Published: October 2022

This article focuses on the relationship between the sociology of utopia and Black visions of liberation. Influential figures from Karl Mannheim to Ruth Levitas have effectively demonstrated the value of a utopian perspective for sociology. However, the African American tradition of utopianism has been largely overlooked in this literature. I argue that the Black standpoint forces a rethinking of the sociological understanding of utopia. More specifically, while most sociologists of utopia straightforwardly associate the desire for a better world with the future, the Black tradition proposes a more expansive understanding of utopia’s temporality. Building on visions of new worlds advanced by WEB Du Bois and the movement for reparations for slavery, I suggest that Black utopia involves a glance backwards to the past, such that the image of a better future is accompanied by the memory of the catastrophe of slavery.
Deindividualising Imposter Syndrome: Imposter Work among Marginalised STEMM Undergraduates in the UK
Authors: Meadhbh Murray Órla , Tiffany Chiu Yuan-Li , Wong Billy , Horsburgh Jo
Published: October 2022

Imposter syndrome is the experience of persistently feeling like a fraud despite one’s achievements. This article explores student experiences of imposter syndrome, based on 27 interviews with marginalised STEMM (Science, Technology, Engineering, Mathematics and Medicine) undergraduates at two pre-1992 elite UK universities. We argue that imposter feelings are a form of unevenly distributed emotional work, which we call imposter work. Drawing on Sara Ahmed’s ‘diversity work’ concept we explore how marginalised students’ imposter feelings are often in response to, and reinforced by, the exclusionary atmosphere of university, resulting in more imposter work to survive and thrive at university. Three key themes are explored – the situated and relational nature of imposter feelings; the uneven distribution of imposter work; and the myth of individual overcoming – before concluding with suggestions for collective responses to addressing imposter feelings.
The Role of the Elite in City Expansion: Nablus City in the Palestinian Central Mountains as a Case Study
Authors: Ghazal Sana , Hammad Ahmad Abu , Abdulfattah Kamal
Published: October 2022

The growth of cities has been facilitated by a variety of factors. One of these is the land annexation by municipality with the assistance of elite individuals. The purpose of this study is to investigate how the elite influenced Nablus—in central Palestine Municipality’s expansion. The study scanned Nablus Municipality Archives, conducted interviews with the annexed villages’ people and used master plans to trace out the city’s expansion across time from 1960 to 2016 (Jordanian rule, Israeli occupation, and Palestinian Authority rule). The ‘elite’ theory has been used to explain how the expansion process succeeded. The analysis found that elite groups proposed and oversaw Nablus Municipality’s expansion boundaries at various times, delayed master plan’s approval and influenced the distribution plots for popular housing projects.
A novel period–based method for the measurement direct current motor velocity using low-resolver encoder
Authors: Top Ahmet , Gökbulut Muammer
Published: October 2022

Direct current (DC) motors—which have widespread usage areas such as industrial devices, automobiles, and household appliances—are also widely used in robotic systems that have developed rapidly in recent years and need precise control. Since the DC motors with encoder on its shaft used in robots have low resolution, accurate speed measurement cannot be made and this makes robot control difficult. In this study, a novel period–based measurement approach is presented to more accuracy and precision determine DC motor velocity at high speed with signals obtained from a low-resolver incremental encoder. First, the signals of the dual channel encoder are applied to the exclusive or gate to produce a single output signal with twice the frequency in order to reduce the number of interrupt pins used in the microcontroller and optimize the program cycle time. Based on the sample count calculated with the entered by user reference speed and microcontroller loop time, the mean filter is then applied to the half-wave period of the signal received through the Arduino board interrupt pin. In order to demonstrate the effectiveness of the method, measurement made with three different methods as follows: traditional period–based method, half-wave period method with only one channel, and exclusive or output signal half-wave period method. The results show the high-speed measurements through the presented method outperform other methods at high DC motor speeds. Especially in robots using more than one motor, the processing load of microcontroller has reduced and enabled the use of other peripheral interfaces by reducing the number of microcontroller pins used for the encoder. In addition, utilizing the results obtained with this method, the proportional–integral–derivative (PID) control of the motors in a four-wheel drive mobile robot is carried out for different speeds.
Binocular visual pendulum angle detection and anti-swing control of quadrotor suspension system
Authors: Zhang Dong , Yang Yunxiao , Han Hengzhi , Hu Yubin
Published: October 2022

Different from the pendulum angle detection by the optical capture system in the indoor environment, it is difficult to detect the pendulum angle of quadrotor suspension system in the outdoor environment. This paper presents a pendulum angle vision measurement scheme based on the model of the quadrotor suspension system, and applied to the quadrotor anti-swing control scheme with feedforward controller. The theoretical expression of the coordinate relationship between the pendulum angle and the spherical symbol is obtained by establishing the mathematical model of the quadrotor suspension system. The coordinates of spherical symbol fixed to the payload are detected by the visual algorithm. Simulations and experiments show that proposed method can accurately identify spherical symbol in sufficient light, and the maximum measurement error of [Formula: see text] angle is −0.024 rad and [Formula: see text] angle is −0.068 rad in the Gazebo simulation. Meanwhile, the results in MATLAB simulation indicate the anti-swing control scheme with feedforward controller can effectively restrain the payload’s swing.
A Phenomenological Divide: Reference Group Consequences for Existential Isolation
Authors: Helm Peter J. , Jimenez Tyler , Carter Skyler , Arndt Jamie

An apparent phenomenological divide between majority and minoritized groups exists in contemporary America in terms of feelings of social connection. Drawing on recent findings relating to existential isolation (i.e., the sense that one is alone in one’s subjective experience), three studies compare these feelings toward one’s in-group and out-group. Study 1 assesses whether Black and White participants vary in their self-reported existential isolation when referencing their own or another racial group. Results reveal Black Americans feel as though other Black Americans share their perceptions more than do White Americans. In contrast, White Americans report similarly shared perceptions by both racial groups. Study 2 (preregistered) assessed these effects with a concealable identity: sexual orientation. Study 3 further replicates these effects and finds effects among Black Americans to significantly differ from a neutral control condition. Implications and future directions for epistemic (in)validation are discussed.
Whose autonomy? Conceptualising ‘colonial extraterritorial autonomy’ in the occupied Palestinian territories
Authors: Dana Tariq , Jarbawi Ali
Published: October 2022

The notion of ‘Palestinian autonomy’ has occupied a central position in Israel’s post-1967 strategic planning in occupied Palestinian territories. Despite that, the notion remains understudied in relation to the regular understanding of political autonomy and its conceptualisation and application in theory and practice. One striking aspect of Israel’s envisioned autonomy for the Palestinians is that it does not resemble any existing model of autonomy implemented around the world today. This article seeks to bridge this conceptual gap by proposing the term ‘Colonial Extraterritorial Autonomy’ as a peculiar mode of colonial governmentality that has been developed in the aftermath of Israel’s 1967 occupation to resolve the territory/demography question in favour of Israel colonial ambition for ‘maximum land with minimum Palestinians’.

Published: October 2022

This paper investigates business diplomacy from the perspective of senior managers and diplomats. In one of the earliest empirical studies, twenty-one official diplomats, CEOs, and business people were interviewed about their perspectives on business diplomacy and its core elements. Data were analyzed using grounded theory. The findings indicate that business diplomacy is a set of multiple integrated qualities concerned with professionally and systematically managing and influencing multiple stakeholders to advance business interests. The findings have led to developing an integrative theory and framework that expands our understanding of business diplomacy. The framework demonstrates the practicability and applicability of business diplomacy in management and business. The study’s implications suggest that businesses incorporate business diplomacy as a strategic tool at the managerial and organizational levels.

The present study explored the relationship between doctors’ career calling and organizational citizenship behavior (OCB). A model proposing that the effect of career calling on OCB mediated by work–life balance (WLB) and job satisfaction was assessed. Data were collected from 670 doctors working in hospitals across Northern India out of which 325 questionnaires were considered for analysis purpose. The results demonstrated that career calling has a significant effect on OCB and WLB and job satisfaction mediates the career calling-OCB relationship. The results of the study suggest that WLB and job satisfaction may signify a critical link between career calling and OCB. Implications surrounding this study and theoretical and practical implications for research and practice are explored.
Is sustainable operations constrained to financial stress in China’s manufacturers? The moderation effect of customer concentration

Published: October 2022

Optimizing customer structure is worthy of developing because products/services offering can promote a delightful financial situation. Inspired by this, we examine the moderation effect of customer concentration targeting at the relationship between financial stress and sustainable operations of China’s manufacturers that exercise substantial impacts on climate change and industrial prosperity. Many industrial sectors, for example, shipbuilding, nonferrous metals, electronic component manufacturing, and food processing, are involved in this study. Empirical results indicate that a higher asset-liability ratio (embodying debt-level stress) and a higher ratio of tax payment to tax rebate (embodying social-level stress) both do not impose a constraint to sustainable operations, but such operations indeed need a response from a lower ratio of total operating cost to total operating revenue (embodying operation-level stress) and a decentralized customer structure. Moreover, customer concentration offers a power to be able to enhance the anti-risk capability of financial stress at the operation-level, thus suggesting narrowing the gap between tax payment and tax rebate. Our analysis transpires that a disharmony between financial stress and sustainable operations can be buffered by decentralizing customer structure. This study contributes to a new insight around the effect of customer in harmonizing finance and sustainability issues in manufacturers of emerging markets, thereby inspiring backbone industries to reach business sustainability assisted by a broad customer group.
“One of Us”: Reframed Labels, Compassion and Hope in Voluntary Prison Work With Ex-Servicemen
Authors: Salt Katie , Kougiali Zetta G.
Published: October 2022

Despite the growing body of literature on Prison Officers and therapeutic practitioners within correctional facilities, comparatively little research exists into prison volunteers. Using semi-structured interviews with caseworkers ( n = 5), analyzed via Interpretative Phenomenological Analysis, this study explores the experience of being a Prison In-Reach Caseworker, supporting the male ex-Armed Forces population in Greater London prisons. Through identifying three superordinate themes of the inherent moral values of the shared past, compassion and “in” versus “out” of the prison system, the study concludes that the caseworkers, working outside the boundaries of the correctional system, reject the label of “criminal” and its associated consequences, choosing instead to attribute value and dignity to the prisoners, both as ex-Armed Forces personnel, and as human beings. The findings offer an insight into the consequences of positive labeling for perspectives of redemption and desistance and suggest the need for further investigation into the experiences and impact of prison volunteers working with different populations.
