Cultural Breadth and Embeddedness: The Individual Adoption of Organizational Culture as a Determinant of Creativity
Authors: Choi Yoonjin , Ingram Paul , Han Sang Won
Published: February 2023

We propose that individuals differ in their ability to generate creative ideas as a function of the values, beliefs, and norms of their social group’s culture they have adopted and routinely use. To generate creative ideas, an individual needs to think differently from their group to generate novel ideas that others cannot, while understanding what the group will view as appropriate and practical. We view culture as a network of cultural elements and decompose individuals’ cultural adoption into two conceptually and empirically distinct dimensions. Cultural breadth, which reflects whether individuals have adopted a broad range of values, beliefs, and norms that span the organization’s culture, contributes to the novelty required for creativity. Cultural embeddedness, which reflects whether individuals have adopted the core values, beliefs, and norms entrenched in the organization’s culture, helps an individual generate ideas that others will view as useful. We predict that individuals with both high cultural breadth and high cultural embeddedness, who we label integrated cultural brokers, will be most likely to generate creative ideas that are novel and useful. We test and find support for our theory in two contexts: an e-commerce firm in South Korea and MBA students at a U.S. university.

The aim of this study was to research the biochemical changes in the hard tissues of the lower “wisdom” teeth, which are at the stage of eruption, with connective tissue dysplasia, depending on sex. The study involved 38 patients aged 17–25 years, who had the extraction of the lower third molars on the left and right for medical reasons. Twenty-one participants in the experiment (16 females, five males) were diagnosed with connective tissue dysplasia; the remaining 17 were healthy and made up the control group (11 females, six males). Samples of enamel, dentin, and enamel–dentin junction were dried to constant weight and examined in tablets pressed in a mixture with potassium bromide on an FT-801 Fourier transform infrared (FT-IR) spectrometer (NPF Simex, Russia) in the range of 500–4000 cm−1. In the IR spectra of the enamel, enamel–dentin junction, and dentin, the absorbance ratio of amide I and II changed significantly and the absorbance of the absorption band of phosphate ions decreased from enamel to dentin. Differences between groups with and without connective tissue dysplasia increased in the following series: dentin, enamel–dentin junction, and enamel. With connective tissue dysplasia, a change in the ratio of the intensities of the absorption bands of amide I and phosphate ions was observed. Normally, the content of organic substances in the enamel of the teeth in the males group is lower than in the females group. Against the background of connective tissue dysplasia, the content of organic substances in the enamel in women decreased while in men it increased, which confirmed the presence of sexual dimorphism during the maturation of hard dental tissues at the eruption stage. The study confirms the opinion of many researchers about the significant role of collagen proteins, which, together with non-collagen proteins, are involved in the development and maturation of dental hard tissues, which are characterized by pronounced heterogeneity and sexual dimorphism in the group with connective tissue dysplasia.

Published: February 2023

In this study, we developed a method to build Raman calibration models without culture data for cell culture monitoring. First, Raman spectra were collected and then analyzed for the signals of all the mentioned analytes: glucose, lactate, glutamine, glutamate, ammonia, antibody, viable cells, media, and feed agent. Using these spectral data, the specific peak positions and intensities for each factor were detected. Next, according to the design of the experiment method, samples were prepared by mixing the above-mentioned factors. Raman spectra of these samples were collected and were used to build calibration models. Several combinations of spectral pretreatments and wavenumber regions were compared to optimize the calibration model for cell culture monitoring without culture data. The accuracy of the developed calibration model was evaluated by performing actual cell culture and fitting the in-line measured spectra to the developed calibration model. As a result, the calibration model achieved sufficiently good accuracy for the three components, glucose, lactate, and antibody (root mean square errors of prediction, or RMSEP = 0.23, 0.29, and 0.20 g/L, respectively). This study has presented innovative results in developing a culture monitoring method without using culture data, while using a basic conventional method of investigating the Raman spectra of each component in the culture media and then utilizing a design of experiment approach.

Published: February 2023

Background

Exposing blood serum samples to ambient white light-emitting diode (WLED) light may accelerate bilirubin photoisomer production. We previously demonstrated the quantitative effect of bilirubin configurational isomers (BCI) on direct bilirubin (DB) value using the vanadate oxidation method. However, the effects of bilirubin structural photoisomers (BSI) remain unclear.

Methods

In Study 1, the relationship between WLED irradiation time and BSI production was examined. Serum samples from five neonates were irradiated with WLED light for 0, 10, 30, 60 and 180 min. Bilirubin isomer concentration and BSI production rates were calculated. In Study 2, we performed quantitative investigation of BSI effect on DB values: Differences in DB, BCI and BSI values before and after irradiation were calculated as ⊿DB, ⊿BCI and ⊿BSI, respectively. Assuming the coefficient of BCI affecting DB values was ‘ a’, relational expression was ⊿DB = a*⊿BSI + 0.19*⊿BCI. Serum samples from 15 neonates were irradiated with green LED light for 10 and 30 s. The respective bilirubin isomer levels were measured, and the coefficient was derived.

Results

In Study 1, the median BSI production rate was 0.022 mg/dL per min in specimens with an unconjugated bilirubin concentration of 10.88 mg/dL. In Study 2, assuming that ⊿DB-0.19*⊿BCI was Y and ⊿BSI was X, the relational expression was Y = 0.34 X-0.03 ( R2 = 0.87; p < .01) and a = 0.34.

Conclusions

Under ambient WLED light, serum sample generated 1.3 mg/dL BSIs in 1 h. Approximately 34% (0.44 mg/dL) of BSI concentrations was measured as DB when using the vanadate oxidation method according to the above equation.
Research on control strategy of seven-DOF vehicle active suspension system based on co-simulation
Authors: Ma Shuo , Li Yongming , Tong Shaocheng
Published: February 2023

In recent years, since the unique advantages in automotive structures, the vehicle active suspension systems have received widespread attentions. A good active suspension system can reduce the vibration and improve the overall performance of the vehicle. Therefore, the design of the controller for the active suspension system to perform autonomous adjustment plays a vital role in vehicle comfort and safety. For the active suspension of the seven-DOF sport utility vehicle (SUV) model, this paper takes the vehicle body acceleration, tire dynamic load and suspension dynamic travel as the indicators to evaluate the performance, and the proportional-integral-derivative (PID) controller is designed to improve the performance of the vehicle active suspension system. Based on the software of MATLAB/Simulink and Carsim, a closed-loop co-simulation model diagram is established, which includes a PID controller module. Meanwhile, the random road input model and the whole vehicle model are constructed in Carsim. Finally, at the speeds of 70, 90, and 120 km/h, the active suspension system under the designed PID controller is simulated and compared with the passive suspension system. The simulation results show that the active suspension system based on PID controller can effectively improve the overall performance of the vehicle, and then the comfort and safety of the vehicle can be further enhanced.
Farm Household Access to Agricultural Credit in Sagnarigu Municipal of Northern Ghana: Application of Cragg’s Double Hurdle Model
Authors: Anang Benjamin Tetteh , Dagunga Gilbert
Published: February 2023

Agricultural credit plays a crucial role in enabling smallholder farmers to increase farm output and reduce rural poverty. Despite this, access to credit remains a challenge to many smallholders. This study thus used cross-sectional data and Cragg’s double-hurdle model to assess the factors affecting farm credit access and the determinants of loan size in the Sagnarigu municipal of northern Ghana. The study found that institutional factors played a significant role in the amounts borrowed. Furthermore, household characteristics had little influence on credit access, whereas farm characteristics played a major role in credit accessibility and loan size. These factors should be considered in designing credit policies for smallholder farmers.
Working From Home and the Triple Role of Women in the Context of COVID-19-Induced Lockdowns in Zimbabwe
Authors: Maviza Gracsious , Thebe Phillip
Published: February 2023

Based on the analysis of 20 in-depth interviews held with employed women in Zimbabwe, this paper uses Moser’s ‘triple role framework’ to make sense of how they juggled production, reproduction and community roles while working from home during the COVID-19-induced lockdowns. It finds that although the enmeshing of the domestic and work spaces yielded different gendered dynamics for women, like ‘role overload’ and the ‘confusion of priorities’, destabilised gender relations and other challenges they faced were primarily perpetuated by patriarchy, hegemony and other dominant gender cultures. Men and women are, therefore, each differently associated with and differently valued in space.
Research Opportunities to Confirm or Dispel the Myths of CECL: Looking Past the Headlines to Actual Results
Authors: Schroeder R. Harold
Published: February 2023

CECL—an accounting response to lessons learned from the 2008 to 2009 financial crisis—like most accounting standards, is not perfect. Imperfections are a direct result of tradeoffs embedded in major new standards issued by the Financial Accounting Standards Board. Tradeoffs arise from cost—benefit judgments made over many years by individual Board members—often holding diverse views about costs and what constitutes decision-useful information. This article contributes to the assessment of those judgments and perceived weaknesses in CECL so that future Boards can continue the iterative process of improving U.S. GAAP. Some stakeholders assert that there are weaknesses because they believe CECL (a) will change how banks are managed; (b) may reduce the lending products provided; (c) necessitates a need for banks to raise capital; (d) would create widespread confusion among investors; and (e) could reduce the availability of credit. Now that CECL is effective for of the entire banking industry, the author believes the Financial Accounting Standards Board (FASB) and public policy-makers will benefit from rigorous academic research to help understand whether CECL met its main objective of providing more decision-useful information about expected credit losses. To achieve this objective, CECL strived to better align measurement of the allowance for credit losses (a valuation account) with changes in credit risk and to require consideration of a broader range of information. This article explores the relevant accounting issues and early financial reporting results to pique the interest of academic researchers.
Why so serious? Studying humor on the right
Authors: Bauer AJ
Published: February 2023

This essay reviews two new books examining different aspects of right-wing humor, “The Souls of White Jokes” (Stanford University Press, 2022) by Raúl Pérez and “That’s Not Funny” (University of California Press, 2022) by Matt Sienkiewicz and Nick Marx. It puts these works into conversation with a longer tendency within right-wing studies to focus on media content and motivations within a negative affective range. By focusing on the positive emotions associated with white supremacy and right-wing media, these books mark an important turning point away from reductionist accounts of the “reactionary mind” and toward a fuller understanding of the complex and contingent motivations of conservatives.
Stress and Resilience among Sexual and Gender Diverse Caregivers
Authors: Fredriksen-Goldsen Karen , Shuman Abandon , Jen Sarah , Jung Hailey H.
Published: February 2023

Little is known about caregiving outcomes of sexual and gender diverse, including LGBT, caregivers. Informed by the Health Equity Promotion Model (HEPM) and Pearlin’s Stress Process Model, we utilized data from Aging with Pride: National Health, Aging, and Sexuality/Gender Study (NHAS), to examine perceived stress among a sample of 754 sexual and gender diverse caregivers using regressions on background and caregiving characteristics and risk and protective factors. Among caregivers, 38% were providing care to a spouse or partner and about one-third to a friend (29%). Higher stress was associated with younger age, lower income, higher education, partner/spouse care, personal care provision, longer caregiving hours, and caregiver cognitive impairment. After including the risk and protective factors from HEPM, victimization, social support, and community engagement significantly predicted perceived stress. Findings contribute to emergent research on caregiving in diverse populations.
Re-Examining the Link Between Premarital Sex and Divorce
Authors: Smith Jesse , Wolfinger Nicholas H.
Published: February 2023

Premarital sex predicts divorce, but we do not know why. Scholars have attributed the relationship to factors such as differences in beliefs and values, but these explanations have not been tested. It is further unclear how this relationship changes by number of sexual partners, or differs by gender. We re-examine this relationship with event history models using data from the National Longitudinal Study of Adolescent to Adult Health. Models include measures of adolescent beliefs and values, religious background, and personal characteristics, as well as approximate number of premarital sexual partners in young adulthood. We find the relationship between premarital sex and divorce is highly significant and robust even when accounting for early-life factors. Compared to people with no premarital partners other than eventual spouses, those with nine or more partners exhibit the highest divorce risk, followed by those with one to eight partners. There is no evidence of gender differences.
The association of hyperhomocysteinemia with acute post-operative complications following coronary artery bypass grafting
Authors: Panicker Bipin Thomas , Veerapudran Sivaprasad , Damodaran Deepthi , Thomas Ronnie , Krishnan Jayakumar Thanathu
Published: February 2023

Background

Hyperhomocysteinemia is associated with an increased risk for cardiovascular diseases. The influence of hyperhomocysteinemia on post-operative events, after coronary artery bypass surgery graft, is less studied.

Methods

This cross-sectional study aimed to determine if hyperhomocysteinemia was associated with post-operative complications in patients < 50 years who underwent off-pump coronary artery bypass graft for coronary artery disease. A set of major post-operative complications were considered as primary outcome measures. The independent effect of hyperhomocysteinemia and other risk factors in the incidence of post-operative complications was determined by multivariate analysis.

Results

The mean homocysteine levels among the study participants who had post-operative complications were significantly higher than those without post-operative complications (17.37 mmol/L vs. 12.84 mmol/L). On multivariate analysis, hyperhomocysteinemia, diabetes mellitus, and higher body mass index (> 25) were significant predictors of adverse events during the post-operative period.

Conclusion

Hyperhomocysteinemia was a significant predictor of immediate post-operative adverse events after coronary artery bypass surgery graft. Necessary precautions and management strategies have to be evolved for these high-risk subsets.

Published: February 2023

Background:

Dyslipidaemia is an important cardiovascular risk factor for people with severe mental illness, contributing to premature mortality. The link between antipsychotics and dyslipidaemia is well established, while evidence on antidepressants is mixed.

Aims:

To investigate if antidepressant/antipsychotic use was associated with lipid parameters in UK Biobank participants and if CYP2C19 and CYP2D6 genetic variation plays a role.

Methods:

Review of self-reported prescription medications identified participants taking antidepressants/antipsychotics. Total, low-, and high-density lipoprotein cholesterol (L/HDL-C) and triglycerides derived from blood samples. CYP2C19 and CYP2D6 metabolic phenotypes were assigned from genetic data. Linear regression investigated aims, adjusted for key covariates.

Results:

Of 469,739 participants, 36,043 took antidepressants (53% female, median age 58, 17% taking cholesterol-lowering medications) and 3255 took antipsychotics (58% female, median age 57, 27% taking cholesterol-lowering medications). Significant associations were found between use of each amitriptyline, fluoxetine, citalopram/escitalopram, sertraline, paroxetine and venlafaxine with higher total cholesterol, LDL-C, and triglycerides and lower HDL-C, compared to participants not taking each medication. Venlafaxine was associated with the worst lipid profile (total cholesterol, adjusted mean difference: 0.21 mmol/L, 95% confidence interval (CI): 0.17 to 0.26, p < 0.001). Antipsychotic use was significantly associated with lower HDL-C and higher triglycerides. In participants taking sertraline, CYP2C19 intermediate metabolisers had higher HDL-C (0.05 mmol/L, 95% CI: 0.01 to 0.09, p = 0.007) and lower triglycerides (−0.17 mmol/L, 95% CI: −0.29 to −0.05, p = 0.007), compared to normal metabolisers.

Conclusions:

Antidepressants were significantly associated with adverse lipid profiles, potentially warranting baseline and regular monitoring. Further research should investigate the mechanistic pathways underlying the protective effects of the CYP2C19 intermediate metaboliser phenotype on HDL-C and triglycerides in people taking sertraline.
Increased fatty acid metabolism and decreased glycolysis are hallmarks of metabolic reprogramming within microglia in degenerating white matter during recovery from experimental stroke

Published: February 2023

The goal of this study was to evaluate changes in metabolic homeostasis during the first 12 weeks of recovery in a distal middle cerebral artery occlusion mouse model of stroke. To achieve this goal, we compared the brain metabolomes of ipsilateral and contralateral hemispheres from aged male mice up to 12 weeks after stroke to that of age-matched naïve and sham mice. There were 707 biochemicals detected in each sample by liquid chromatography-mass spectroscopy (LC-MS). Mitochondrial fatty acid β-oxidation, indicated by acyl carnitine levels, was increased in stroked tissue at 1 day and 4 weeks following stroke. Glucose and several glycolytic intermediates were elevated in the ipsilateral hemisphere for 12 weeks compared to the aged naïve controls, but pyruvate was decreased. Additionally, itaconate, a glycolysis inhibitor associated with activation of anti-inflammatory mechanisms in myeloid cells, was higher in the same comparisons. Spatial transcriptomics and RNA in situ hybridization localized these alterations to microglia within the area of axonal degeneration. These results indicate that chronic metabolic differences exist between stroked and control brains, including alterations in fatty acid metabolism and glycolysis within microglia in areas of degenerating white matter for at least 12 weeks after stroke.

Authors: Gong Yinhua , Wei Wei , Zhang Wei , Han Qiang , Zhang Chunge
Published: February 2023

Objectives

This study evaluated the effect of implementing a hierarchical pharmaceutical service pattern based on the knowledge–attitude–practice (KAP) intervention theory on patients with systemic lupus erythematosus.

Methods

Eligible patients were randomly divided into an intervention or control group. Pharmaceutical service classification criteria were formulated and used to provide patients with differing levels of pharmaceutical services. The classification scores and KAP levels of patients before and at various time points after the intervention were analyzed. The rates of acute attacks and adverse reactions, related clinical test indices, and disease activity were evaluated in both groups.

Results

After 9 months of intervention, the proportions of first- and second-level services in the intervention group declined by 14.43% and 3.94%, respectively, compared with the control group, and the rates of acute attacks and adverse reactions declined by 18.26% and 12.43%, respectively. The KAP level, clinical test indices, and disease activity were significantly different between the groups.

Conclusion

Providing patients with systemic lupus erythematosus with pertinent hierarchical pharmaceutical services based on the KAP theory was instrumental in changing patients’ behavior and contributed to facilitating disease self-management, thus improving the quality of pharmaceutical services.
Development and validation of the Singing Voice Function Self-Efficacy Scale (Singing-VoSES)
Authors: Lã Filipa MB , Fiuza Mauro B , Ramírez Ana M , Ardura Diego
Published: February 2023

This investigation aimed at developing and validating a scale measuring perceived self-efficacy in singing with respect to voice function, the Singing Voice Function Self-Efficacy Scale ( Singing-VoSES). Voice experts validated an 18-item scale, subsequently administered online, targeting specifically professional and semi-professional female singers. These inclusion criteria were met by a total of 439 participants. Results of both exploratory and confirmatory factorial analysis suggest that Singing-VoSES is a valid scale, with items grouped into three self-efficacy dimensions: Higher Range and Transitions, Middle Range and Lower Range. Middle Range and Lower Range dimensions were both significantly higher than Higher Range and Transitions. Singing high notes and notes within transitional vocal ranges require a refined neuromotor control of the voice, and thus may be particularly challenging. Comparisons between pre and postmenopausal singers were made, as menopause has been associated with changes in voice function. Significantly lower self-efficacies for Higher Range and Transitions and Middle Range were found in post as compared to premenopausal singers. This result, together with the possible lack of coping strategies, may contribute to negative impacts on singers’ performances and, ultimately, lead to premature retirement from public performances. Thus, monitoring self-efficacy with respect to voice function seems relevant, particularly when assisting singers experiencing menopause-related voice difficulties.
The assemblages of (counter) spectacle – mega-retail in post-dictatorship Chile and beyond
Authors: Miller Jacob C
Published: February 2023

Spectacle, once a key term for critical theories, has had limited theoretical development in recent decades. To make sure the concept remains relevant today, this paper turns to actor-network theory (ANT) and assemblage theories to reconceptualize what the spectacle is and how it operates today. Working with a case study of a controversial urban spectacle in southern Chile – a new shopping mall, the “Mall Paseo Chiloé” – this paper explores a set of findings that illustrate what these approaches have to offer. First, in viewing the spectacle as a hybrid entity, we uncover vital forces inside what might at first appear to be irrelevant features of the building's architectural design. At the same time, this approach includes the forces of ambivalent desire and fluidity that reveal the dynamics of resistance inside that same design. As such, this paper focuses on a specific aspect of this building that makes it a unique form of counter-spectacle.
Ten theses on the new state capitalism and its futures
Authors: Alami Ilias
Published: February 2023

Global capitalism is currently experiencing a turbulent and polymorphous (geo)political reordering, encompassing multiple transformations in the landscapes of state intervention, and a drastic reconfiguration of the state's role as promoter, supervisor and owner of capital across the world economy. Can the concept of state capitalism aid us in grasping these transformations conceptually? My answer is yes, with the proviso that state capitalism is neither conceptualised as a national (or regional) variety of capitalism, nor as a new regime of accumulation, but as a flexible means of problematising this historic arc in the trajectories of state intervention. Based on this approach, I offer in this essay ten theses on the new state capitalism, its roots in the dynamics of capital accumulation, its relations to broader material conflicts and its potential futures.
The benefits and limitations of populism for radical-left parties
Authors: Dar Or
Published: February 2023

The 2008 economic crisis created an opportunity for radical-left parties, the most consistent critics of neoliberalism. While some populist parties break through, other left parties did not take advantage of the opportunities created. There are two main arguments in this article. First, left-wing populists were more successful since they adjusted to the dynamics of the class struggle and to the requirements of mobilizing diffused frustrations. The class struggle is split between a union-based struggle, and a non-union-based one, the latter becoming more central in recent decades. It is composed of spontaneous bursts of protest not leading to the building of organized power, making it much harder to stably harness by left parties compared with past union-based struggles. Non-union-based class struggles open a cycle that can be taken advantage of by left parties that conform to its logic and are in a strong enough party system position, as did Syriza and Podemos. Second, left-wing populists nevertheless reached an impasse, since they could unite the left voters’ bloc only under unique conditions. Labor market ‘outsiders’, more precarious, educated and urban youth were at the core of last decades’ protest movements and radical-left parties’ electoral surges. Labor market ‘insiders’, non-precarious and relatively economically secure left voters who opted for the left-wing populist option only as a last resort. Populist radical-left parties could not unite the popular bloc entirely, as significant parts of the working class were less accessible to them. Furthermore, populist radical-left parties did not contribute to the building of mass subaltern organizations, leaving little organized heritage. Since populism is more in tune with the dominant form of class struggle, radical-left parties should embrace it, but due to its limitations, it has to be complemented with ‘class-for-itself’ political methods.
Prognostic value of alkaline phosphatase and bone-specific alkaline phosphatase in breast cancer: A systematic review and meta-analysis
Authors: Jiang Chengying , Hu Fangke , Xia Xiaoqing , Guo Xiaojing
Published: February 2023

Numerous studies have reported the clinical value of alkaline phosphatase (ALP) and its bone-specific isoforms (bone-specific alkaline phosphatase (BAP)) in breast cancer. The purpose of this meta-analysis was to summarize the prognostic value of serum ALP and BAP in breast cancer, especially focused on bone metastasis and survival. PRISMA guidelines were followed to conduct this review. Observational studies were searched in PubMed, Cochcrane Library and EMBASE to January 1, 2022. Data were extracted to explore the prognostic value of ALP and BAP. The quality of the included studies was assessed and the outcome effects were evaluated. Subgroup and sensitivity analyses were performed to explore the potential sources of heterogeneity. Publication bias was assessed. There was a total of 53 studies with 22,436 patients included. For the primary outcome of survival, high levels of both ALP and BAP were associated with short survival time. The hazard ratio of high ALP level on overall survival was 1.72 (95% CI 1.37, 2.16, P < 0.001). For the secondary outcomes, a high ALP level (not BAP) was detected in breast cancer compared with healthy controls, and high levels of both ALP and BAP were risk factors for bone metastasis, while ALP (not BAP) was a risk factor for non-bone metastasis. This study showed that high levels of both serum ALP and BAP were associated with metastasis (BAP was associated with bone metastasis) and survival in breast cancer. The biomarkers could provide useful information for the early diagnostic assessment and monitoring in the follow-up of breast cancer patients.

Published: February 2023

Following the 2015 release of Truth and Reconciliation Commission’s Final Report in Canada, disciplines at various levels of federal and provincial infrastructures have begun taking up reconciliation in their practice. In 2018, the Canadian Psychological Association (CPA) and the Psychology Foundation of Canada (PFC) released a joint response, which outlines how the profession has violated its own ethics with respect to practice with Indigenous peoples and how to move forward through a reconciliatory process as individuals and as a profession. What is unclear is how individual psychologists and psychologist teams are taking up reconciliation in their practice, years after the CPA/PFC Response to the TRC. As psychologists and other helping professionals learn about the history of marginalization of Indigenous peoples within the discipline of psychology, many may be searching for more specific examples of how to begin or extend the process of addressing reconciliation. This Brief Commentary will focus on the practice of one group of school psychologists working in a public school district in an urban setting in British Columbia who are engaging in relationship development with First Nations communities on whose territory the district resides. Psychologists from the team will contribute reflections regarding their experience with the process as a whole. These psychologists have been part of a school psychology team that has been involved in reconciliation for some time and are actively pursuing individual and group accountability toward Indigenous people. The context of the group and steps taken from the team’s personal and professional introduction to the topic of reconciliation, and facilitators and considerations that impacted the group’s progress will be explored.

Research on autonomous dynamic real-time capture of robot based on hybrid prediction model
Authors: Hu Ming , Guo Yufeng , Yang Jing , Yang Fan , Yao Zhongshuai
Published: February 2023

The trajectory of the dynamic target is an important basis for the robot to capture the action, and its advanced prediction precision plays a decisive role in achieving efficient capture. In this paper, a dynamic adaptive weighting method is proposed to establish a hybrid prediction model of GM (1,1) and SESM. The weights are allocated in real time, according to the prediction accuracy to improve the prediction accuracy of a single model and enhance the applicability of spatial trajectory prediction. Then, based on the rolling prediction principle, a high-precision advanced prediction method of the hybrid model is created. Compared with the advanced prediction of the model itself, the average prediction errors of the spatial arc and straight line verification trajectories are reduced by 40.26% and 49.77% respectively. The simulation model of robot dynamic target capture is built in Matlab, and the measured trajectory is used as the target trajectory. The robot capture experiment platform is built, and the target motion trajectory is collected by the camera in real time to capture the experiment, which verifies the effectiveness of the proposed method in actual capture.
Adaptive swing reduction control of double-pendulum tower crane time-varying system based on real-time update mutation factor
Authors: Yumin He , Jing Zhou , Jinhua Zhang , Xiansong Zhang , Ying Han , Ting Luo , Difang Liu , Xinyan Men
Published: February 2023

As representative underactuated and nonlinear systems, tower crane involves the multi-direction movement of the payload and even shows a more complex double pendulum in many actual situations, which makes the control problem more complicated. Most anti-swing controllers are mainly based on the linear design of tower crane dynamics at present and are insensitive to the position far from the equilibrium point. The time-varying cable length and double-pendulum effect are not taken into account simultaneously. Aiming at the problem of anti-swing control, a dynamic model of time-varying cable length tower crane with double-pendulum effect is established and an adaptive control method is proposed, which used the adaptive mutation strategy to update the mutation factor in real-time, and the parameters of the controller are tuned by an improved differential evolutionary algorithm. The simulations and experiments are carried out to verify the better optimization ability and faster convergence speed of the improved evolutionary algorithm in the process of parameter tuning and the effectiveness and superiority of the proposed control method are verified by comparing it with PID (proportion integration differentiation) and LQR (linear quadratic regulator) controllers.
Distributed formation control of multi-vehicle system based on hybrid relative measurements
Authors: Pan Kunpeng , Lyu Yang , Feng Zhaowen , Pan Quan
Published: February 2023

Formation control has been studied extensively along with the potential applications of multi-vehicle system in various areas. In this paper, a distributed control scheme based on the relative bearing and distance measurements is proposed. The main difference from the existing works lies in that the proposed control scheme can realize unambiguous formation tracking while considering the task-specification and environment constraints under practical bearing and distance sensing conditions. First, the uniqueness of the formation based on relative bearings and distances is investigated and the sufficient condition is provided. Further, the distributed formation controllers that are able to dynamically track the formation with both leaderless and leader-follower setups are designed under practical sensing conditions. In the end, to validate the effectiveness and practicability of the proposed distributed hybrid measurements based formation control scheme, both simulations based on synthetic scenarios and experiments with quadrotors equipping cameras and Ultra-Wide Band (UWB) transmitters are carried out. The simulation and experiment results show that the proposed controllers are able to track the desired formation pattern based on the bearing and distance measurements.

As an important component, the gear pair is frequently used in the mechanical transmission. If there is a localized spalling defect on the gear pair, the double shock phenomenon in the vibration response can be observed. In order to reveal the mechanism, an 8DOFs dynamic model for the gear pair is established, the symmetric and asymmetric rectangular spalling defects are considered, the torsional deformation is introduced. Meanwhile, the change law of the double shock during the defect expansion is explored. From the results, the double shock is caused by multiple changes in meshing stiffness, the amplitude and distribution range are closely related to the defect sizes. When the localized defect is extended along the length and depth directions, the amplitude of the double shock is significantly increased. If the defect area is asymmetric along the center plane, the torsional deformation of the gear pair will be generated. Then, the meshing stiffness is reduced, and the double shock becomes more obvious. Finally, through the finite element method and the experiment, the established model is confirmed.

Environmental awareness brings the attention towards the biodegradable natural fibre composites in most of the industrial and manufacturing sectors. The light weight, low cost, ease-in-availability, biodegradability and non-toxic inherited nature of natural fibres have predominated over the synthetic fibres. Jute hybrid composites are very common from the early decades for their superior mechanical performance. In this research work, the woven form of natural fabric like jute and sisal has been hybridised with synthetic S-glass fabrics have been reinforced in epoxy matrix by most convenient and economic hand layup process. The nano-marble dust, the waste of marble industry was used as filler in the hybrid composites. The natural fabrics are mercerised before fabrication for improvement in fibre texture in order to get better interfacial bonding, as waste materials, wax, lignin contents and other foreign ingredients are removed by the process. The various characteristics such as physical, mechanical and thermal are studied for the prepared composite specimens. It is observed that the tensile strength of the composite improved drastically due to the presence of nano-marble dust. The impact strength is also enhanced due to the addition of nano-marble dust and more no. of glass fabric layers in composite. Thermo-gravimetric analysis (TGA) revealed that the composite containing nano-marble dust and glass fibre mat exhibited maximum degradation temperature of 410.4°C.

Friction stir welding (FSW) has played a significant role in joining aerospace alloys. During this process, the tool rotational (TRS) speed has been found to significantly affect heat generation compared to other parameters. Therefore, the study has investigated the effect of heat generation on force-torque and mechanical properties at different tool rotational speeds (TRS) in the FSW process through experimentation followed by Artificial Neural Network (ANN) technique. Further, the influence of different TRS ranging between 600 and 1800 rpm with an increment of 400 rpm on considered responses; namely thermal weld cycle, microstructure, and grain distribution in nugget zone (NZ) for 2050-T84 Al-Cu-Li alloy plates, welded using FSW were also investigated. It is observed that the vertically downward force (Z-force), longitudinal force (X-force), and spindle torque (Sp. T) decrease with increasing TRS. It is also observed an increasing (up to 1400 rpm) and then decreasing trend for tensile strength and hardness of welded samples. Moreover, the generation of frictional heat and grain size in NZ is increased with increasing TRS from 600 to 1800 rpm. However, the scanning electron microscope (SEM) micrographs of all-welded samples revealed a ductile mode of tensile fracture. Furthermore, the obtained experimental results were validated using the ANN technique. A quite better agreement has been established among the predicted outcomes from ANN with experimental results.

This paper introduces the adaptive fuzzy control scheme as a promising control technique for cancer treatment from a theoretical point of view. A mathematical model describing the dynamics of tumor growth under the drug interventions of chemotherapy and antiangiogenic therapy is considered. The model incorporates the effects of normal cells, cancer cells, and endothelial cells. Then, the control goals in cancer treatment are discussed and the desired trajectory for a typical patient is derived using the optimal control theory. Since the dynamic model of tumor growth is not accurate and also varies from patient to patient, an adaptive fuzzy controller is designed to make the outputs of the dynamic model track the desired trajectory. The proposed control system is model–independent and identifies the dynamic model of tumor growth over time. The performance of the designed controller is assessed by several numerical simulations. Finally, a hardware–in–the–loop simulation is conducted to validate the results.

Objective

Test an intervention for individuals with schizophrenia at an Adult Inpatient Unit with employment and social inclusion goals, compared to treatment as usual.

Method

A single-blind, randomised, controlled trial assigned 25 participants to treatment as usual and 26 participants to receive an Individual Placement and Support (IPS) Disability Employment Service (DES) information pack and an offer of support from a nurse. Outcomes were measured at 6 and 12 months using Job Acquisition, IPS DES employment provider, Activity Participation Questionnaire-Revised, Brief Psychiatric Rating Scale, and Adult Hope Scale questionnaires, and Digit Span and Trail Making tests.

Results

The intervention did not result in significant contact with the DES employment provider or paid employment outcomes. Secondary outcomes from combining groups due to high attrition rates: A significant proportion of participants obtained unpaid work from baseline to 6 months follow-up ( N = 24, p = 0.001).

Conclusions

The ‘light touch’ intervention did not promote change. More support is required during inpatient admissions and after discharge to assist people with schizophrenia achieve their vocational goals.

Electronic cigarettes (e-cigarettes) provide a novel source of nicotine and may lead to experimentation by adolescents and eventually to their use of conventional cigarettes. The National Youth Tobacco Survey collected information from a nationally representative sample of students in 2016 to determine their experiences with conventional cigarettes and e-cigarettes, their intentions to use these products in the future, and their perceptions of harm and addiction associated with these products. We analyzed these data with ordered probit regression models to determine possible associations with the intention to try e-cigarettes and conventional cigarettes. This survey included 20,520 respondents, 50.6% were male, 5.9% had used conventional cigarettes, and 9.0% had used e-cigarettes. Approximately 10% thought e-cigarettes caused no harm, 3.7% thought that conventional cigarettes caused no harm, and 52.5% thought that e-cigarettes were less harmful than conventional cigarettes. Less than 1% of the students responded “Definitely yes” to the question, “Do you think you will try an e-cig?” The odds ratios for an intention to try e-cigarettes increased as the perception of harm decreased; these ratios increased from 1.0 for “A lot of harm” to 5.85 (95% CI: 3.51, 9.75) for “No harm.” In 2016, the majority of students thought that e-cigarettes could cause some harm. This survey indicates that most students have not tried e-cigarettes or conventional cigarettes. The minority of students who think that e-cigarettes pose no harm and students in the ages 14 and 16 are more likely to try them.
