Stiffness reliability analysis of harmonic drive considering contact pairs wear
Authors: Zhang Xian , Zhang Changming , Wang Peng , Yang Fan , Peng Chunlei 
Published: June 2024

PurposeThe purpose of this paper is to analyze the stiffness reliability of harmonic drive (HD) considering contact pairs wear.Design/methodology/approachIn terms of theoretical calculation, the contact pairs wear of HD are calculated based on Archard wear formula and the relative motion characteristics of contact pairs. According to the motion trajectory of flexspline teeth, the teeth backlash and the number of meshing teeth, the meshing stiffness and overall stiffness of HD are analyzed considering the wear and its randomness of contact pairs. Combined with Monte Carlo Simulation, the stiffness reliability evaluation method considering contact pairs wear is proposed, and the result of this method is verified by the stiffness reliability result deduced from the stiffness degradation measurement data.FindingsConsidering contact pairs wear, during operation, the teeth backlash increases, the number of meshing teeth decreases, the meshing stiffness decreases, ultimately leading to a gradual decrease in the overall stiffness of HD. When only one type of contact pair wear is considered, the influence of flexspline and circular spline contact pair wear on HD stiffness reliability is greater. Compared with the stiffness reliability evaluation results obtained from the stiffness degradation data in the literature, the mathematic expectation of stiffness degradation failure life distribution obtained from the proposed method is relatively bigger.Originality/valueThe stiffness reliability evaluation method of HD considering contact pairs wear is firstly proposed. The stiffness reliability evaluation result from theoretical calculation is verified by the stiffness reliability results deduced from HD stiffness degradation measurement.
A robust approach for aspect-based sentiment analysis using deep learning and domain ontologies
Authors: Sharma Srishti , Saraswat Mala 
Published: June 2024

Purpose
The purpose of this research study is to improve sentiment analysis (SA) at the aspect level, which is accomplished through two independent goals of aspect term and opinion extraction and subsequent sentiment classification.

Design/methodology/approach
The proposed architecture uses neighborhood and dependency tree-based relations for target opinion extraction, a domain–ontology-based knowledge management system for aspect term extraction, and deep learning techniques for classification.

Findings
The authors use different deep learning architectures to test the proposed approach of both review and aspect levels. It is reported that Vanilla recurrent neural network has an accuracy of 83.22%, long short-term memory (LSTM) is 89.87% accurate, Bi-LSTM is 91.57% accurate, gated recurrent unit is 65.57% accurate and convolutional neural network is 82.33% accurate. For the aspect level analysis, ρaspect comes out to be 0.712 and Δ2aspect is 0.384, indicating a marked improvement over previously reported results.

Originality/value
This study suggests a novel method for aspect-based SA that makes use of deep learning and domain ontologies. The use of domain ontologies allows for enhanced aspect identification, and the use of deep learning algorithms enhances the accuracy of the SA task.
Impedance-based null-space control of redundant torque-controlled robot
Authors: Zhang Leigang , Yu Hongliu , Cui Xilong 
Published: June 2024

Purpose
The null-space projection method is commonly adopted for controlling redundant robots, which undoubtedly requires the robot Jacobian matrix inverse. This paper aims to provide a novel control scheme, which enables null-space control of redundant robots without conflict with the main task space.

Design/methodology/approach
In this paper, an impedance-based null-space control approach for redundant robots is proposed. The null-space degrees of freedom are separated from the primary task space by using the eigenvalue decomposition. Then, a joint impedance controller spans the null space and is reflected into the joint space to manage the redundancy. Finally, several experiments have been conducted to evaluate and validate the performance of the proposed approach in comparison with the null-space projection method under various situations.

Findings
Experiment results show that no significant differences were observed between the different filling eigenvalues in the proposed approach under different null-space dimensions and motion velocity. Besides, comparative experiment results demonstrate that the proposed method can achieve comparable results to the null-space projection method. Nevertheless, the suggested approach has benefits regarding the quantity of control parameters in addition to not requiring a Jacobian inverse. Notably, the performance of the proposed method will improve as the null-space dimension increases.

Originality/value
This study presents a new control method for redundant robots, which has advantages for dealing with the problems of controlling redundant robots compared to the existing methods.
Bundle manipulation: the use of accounting and textual obfuscation
Authors: Le Maux Julien , Smaili Nadia 
Published: June 2024

Purpose
The purpose of this study is to explore whether managers and firms engage in bundle manipulation. It examines the effect of discretionary accruals and real activities manipulation on the level of complexity in annual reports.

Design/methodology/approach
The findings from the examination of the 1,435 annual reports of Canadian listed firms engaging in discretionary accruals and real activities manipulation indicate that these firms produce complex annual reports.

Findings
The authors, therefore, suggest that managers and firms use bundle manipulation, both accounting and textual, to mislead shareholders and stakeholders. The analyses also suggest that it is more difficult to detect the manipulation of real activities than discretionary accruals through textual analysis.

Originality/value
The authors propose an in-depth examination of how accruals and real activities manipulations affect the level of readability of firms’ reports. Furthermore, the authors suggest that firms engage in bundle manipulation, including accounting and textual manipulation. This paper aims to provide an in-depth analysis of the relationship between accounting and linguistic manipulations. The study suggests that investors could use the complexity of annual reports to detect earnings management. More specifically, it seems that firms engaging in discretionary accruals produce complex annual reports.
Perceived service quality and risks towards satisfaction of online halal food delivery system: from the Malaysian perspectives
Authors: Osman Ismah , Omar Emi Normalina , Ratnasari Ririn Tri , Furqon Chairul , Sultan Mokh Adib 
Published: June 2024

Purpose
The purpose of this study is to ascertain service quality (halal values, assurance, meal quality, reliability, security, system and traceability) and perceived risks (financial, quality, environment, social, time, psychology and health) and its influence on satisfaction, as well as trust concerning online halal food delivery system (OHFDS).

Design/methodology/approach
This study uses quantitative methodology, through an online survey, by using purposive sampling across a sample size of 423 respondents. The analysis of data was conducted using SmartPLS.

Findings
The results of the findings indicate that assurance and halal values have an influence on satisfaction, as well as trust; nonetheless, only reliability has an impact on satisfaction. On the other hand, perceived health and financial risks have negative influence on trust and satisfaction toward OHFDS. In addition, perceived psychological and financial risks are found to have negative impacts on trust of OHFDS.

Research limitations/implications
The theoretical value of this study is the testing of perceived service quality and risks concerning OHFDS in the same model, thereby contributing to a deeper understanding of its impact on trust and satisfaction toward the online food service delivery industry. The results of this study may appear as a starting point for researchers who wish to conduct further studies on the same topic.

Practical implications
This study suggests that the service providers need to boost their efforts in establishing high quality service and, simultaneously, reduce perceived risks, to develop satisfaction and trust toward OHFDS.

Social implications
The long-term consequence of the business's achievement is that it makes it simpler for customers to have confidence in, be satisfied with and recommend the service providers to others.

Originality/value
A number of research investigations have been conducted among Muslims, specifically in the Asian region, which have yielded crucial data regarding consumer behavior toward halal products, such as food and tourism. This study, nonetheless, remains close with other studies on halal food, except that it adds together the knowledge of perceived quality and risks, as to gain a deeper understanding of the experience customers have on food, through online service delivery.

Authors: De Sá Rachel Borges Cyrino , Tessmann Mathias Schneid , Pinto Alex Cerqueira 
Published: June 2024

PurposeThis paper seeks to investigate whether women exhibit greater risk-aversion behavior than men in investments by estimating the influence of gender on portfolio volatility.Design/methodology/approachData on the volatility observed in the portfolio in the last six months, last twelve months and since the individual became a client at one of the largest financial institutions in Brazil – and in Latin America – that operates in the capital markets are used. In addition to the gender explanatory variable, socioeconomic variables such as age, marital status, suitability, residence in capitals and declared assets are controlled, and multiple linear regression models are controlled.FindingsThe results show that gender is statistically significant in all models estimated to explain the volatility of investment portfolios, saying that women are more risk averse than men.Originality/valueThese findings are useful for the scientific literature that investigates behavioral finance by bringing empirical evidence for Brazil.
More than words: PhD students and critical reading
Authors: FitzPatrick Beverly , Chong Mike , Tuff James , Jamil Sana , Al Hariri Khalid , Stocks Taylor 
Published: June 2024

Purpose
Many PhD students have strong reading comprehension, but some struggle with how to read critically. The purpose of this study is to understand what reading looks like for PhD students, what they are doing when they read scholarly texts and how they bring these texts to life in meaningful ways.

Design/methodology/approach
The authors conducted a self-study using a phenomenological research approach. Five PhD students collected data on their academic reading for three weeks, including the references, purpose for reading, and what they did as part of the reading process. Second, students analyzed their reading processes according to Paul and Elder’s (2006) intellectual standards. Third, students participated in two semi-structured discussions about the standards in relation to doctoral reading.

Findings
Reading is inseparable from thinking, with Paul and Elder’s (2006) intellectual standards (e.g. clarity, relevance, logic and fairness) playing an essential role in the academic reading process. Alongside these cognitive aspects of reading, the affective domain also contributes to the reading process.

Originality/value
This study is important because being able to read scholarly work is crucial for completing doctoral programs, conducting research, and publishing. We suggest that just as we need to teach writing, we need to acknowledge that many doctoral students need guidance to read scholarly texts, they need to be educated on the intellectual standards, and supervisors must rest their assumptions about doctoral reading and explicitly teach these processes.
Towards a Synergistic Multi‐stakeholder Approach to CSR in Crisis: Learning from Large Global Firms’ Responses to COVID‐19
Authors: Bamiatzi Vassiliki , Brieger Steven A. , Manning Stephan , Shi Shiqianbao , Islam Tahir 
Published: June 2024

AbstractFirms are increasingly expected to engage in corporate social responsibility (CSR) in reaction to external crises. Yet, we still know little about how they do it. This study discusses what we can learn from how large global firms responded to the COVID‐19 pandemic. Employing a cluster analysis on Fortune Global 500 firms, our findings reveal that to meet both institutional and economic pressures posed by the crisis, global firms adopted what we call a synergistic multi‐stakeholder approach by addressing the needs of multiple stakeholder groups simultaneously through transferable response strategies. These strategies varied by firm, ranging from donations and educational initiatives to collaboration and minimal support. We discuss the characteristics and potential drivers of each strategy. Our findings suggest that synergistic CSR strategies combine (social) value creation with operational efficiencies across stakeholder groups, with critical implications for how firms may respond to future disasters and crises.

Authors: Tondo Leonardo , Miola Alessandro , Pinna Marco , Contu Martina , Baldessarini Ross J. 
Published: June 2024

AbstractBackgroundAnticipating diagnostic change from major depressive (MDD) to bipolar disorder (BD) can support better prognosis and treatment, especially of depression but is challenging and reported research results are inconsistent. We therefore assessed clinical characteristics associated with diagnostic change from MDD to BD with antidepressant treatments.MethodsWe compared characteristics of 3212 initially MDD patients who became (hypo)manic during antidepressant treatment to those with stable MDD diagnoses as well as with cases of stable, spontaneous BD, using standard bivariate and multivariate statistics.ResultsAmong MDD patients, 6.69% [CI: 5.85–7.61] changed to BD, mostly type II (BD2, 76.7%). BD‐converters had higher rates of familial mood disorders (74.1% vs. 57.1%) or BD (33.7% vs. 21.0%) and 2.8‐years younger onset than stable MDD patients. They also had more prior depressive recurrences/year, years‐of‐illness, mood‐stabilizer treatment, divorces, fewer children, more suicide attempts and drug‐abuse, and higher intake cyclothymia, YMRS and MDQ scores. Predictors independently associated with diagnostic conversion were: more familial BD, depressions/year, unemployment, cyclothymic temperament, suicidal ideation or acts, and fewer children. BD‐converters vs. spontaneous BD cases had significantly more suicide attempts, BD2 diagnoses, and affected relatives. Converting to vs. spontaneous BD1 was associated with more ADHD, more suicidal ideation or behavior, MDI course, and younger onset; converting to vs. spontaneous BD2 had more episodes/year, unemployment, ADHD, substance abuse, suicidal ideation or attempts, and more relatives with BD.ConclusionsFew (6.69%) initially MDD subjects converted to BD, most (76.7%) to BD2. Independent predictive associations with diagnostic change included: familial BD, more depressions/year, unemployment, cyclothymic temperament, suicidal behavior and fewer children. Notably, several characteristics were stronger among those changing to BD during antidepressant treatment vs. others with spontaneous BD.

AbstractBackgroundReproductive health and mental health are intertwined, but studies investigating family planning needs and desire for children in mental healthcare are scarce.MethodsWe studied the experiences of (former) patients, those with close relationships with the (former) patients (close ones) and mental health professionals (MHP) on discussing family planning and desire for children in mental healthcare. We combined quantitative (two nationwide surveys) and qualitative data (four focus groups) in a mixed‐methods approach with sequential analytical design.ResultsCombined data from focus groups (n = 19 participants) and two surveys (n = 139 MHPs and n = 294 (former) patients and close ones) showed that a considerable group of MHPs (64.0%), patients (40.9%) and close ones (50.0%) found that family planning should be discussed by a psychiatrist. However, several obstacles impeded a conversation, such as fear of judgment, lack of time and knowledge and limited opportunity for in‐depth exploration of life themes in therapeutic relationships.ConclusionsTo increase the autonomy of patients in discussing family planning, we suggest MHPs explore the desire to discuss family planning with all patients in the reproductive phase of life, prior to discussing contraceptive care. MHPs should receive education about psychiatric vulnerability in relation to family planning and desire for children, and patients and close ones should be empowered to initiate a conversation themselves.

Published: June 2024

AbstractBackgroundThe potential impact of diabetes mellitus type 1 (DM1) on male fertility is currently poorly defined. Hyperglycaemia and insulin deficiency may affect spermatogenesis. Some evidence suggests that men with DM1 have a significant reduction in progressive sperm motility, sperm morphology and semen volume, without significant changes in sperm concentration and count, but definite data are lacking.ObjectivesTo evaluate the impact of DM1 on clinical parameters related to male fertility and semen analysis.Materials and methodsWe compared a court of 42 male DM1 patients with 43 nondiabetic subjects overlapping in age and remaining clinical data in an observational case‐control study. All subjects underwent a comprehensive andrological reproductive evaluation, including medical history, physical examination, and semen analysis. We collected biochemical data in all patients with DM1, while diabetic patients with any alteration in semen parameters underwent sperm culture and scrotal ultrasound. In addition, all men completed the IIEF‐5 questionnaire (International Index of Erectile Function‐5) and the AMS (Aging Male Symptom score) questionnaire.ResultsPatients with DM1 had a higher prevalence of infertility, erectile dysfunction and worse semen parameters compared with controls. In particular, semen volume, total sperm count, and total and progressive sperm motility were significantly lower (p < 0.001, p = 0.003, p = 0.048, and p = 0.022 respectively). In addition, the rate of semen anti‐sperm antibody positivity, the AMS score and FSH levels were higher.Discussion and conclusionSeveral mechanisms may contribute to these semen alterations in DM1 patients, such as oxidative damage to spermatogenesis, seminal infections and pelvic neurological changes. These data suggest that patients with DM1 should be counselled from an andrological‐reproductive point of view.
The Salvage Frontier: Place, Nature, and Neoliberalism in a Small Northern Town
Authors: Erickson Bruce 
Published: June 2024

AbstractThe transition to a neoliberal economy that has been happening in Northern Canada has promised increasing control over resources to residents. Yet, the neoliberal approach carries significant risk, especially as it attempts to extract profit from failed and abandoned public projects—what Anna Tsing calls “salvage accumulation”. In Churchill, Manitoba, the primary economic drivers—shipping and tourism—have turned the town as a place into a particular type of salvage commodity. Built upon abandoned infrastructure, non‐human nature, the collapse of other industries, and the changing climate, these industries rely upon the overall place image of Churchill to bring non‐market goods into the commodity process. This process removes local control of place image (and experience) yet still embeds the risk of the venture in the location itself. Salvage accumulation as an entrepreneurial practice unequally distributes the risk onto residents while allowing the profits to accrue elsewhere.
Direct Action at Home: Performative Spaces of Tenant Resistance in Los Angeles
Authors: Moatasim Faiza 
Published: June 2024

AbstractGiven the rising number of evictions in the United States, self‐organised and housing‐insecure tenants actively fight back against their harassment and displacement. Because of the high rate of informal evictions, housing struggles between tenants and landlords are not only fought in courts; they often take place at the homes that they themselves and their landlords occupy. How do precariously housed tenants resist their displacement, and turn domestic spaces into spaces of tenant protest and resistance? This article examines the performative capacity of residential buildings in tenant direct actions in Los Angeles. By protesting at their own homes and those of their landlords, tenant groups claim control over their domestic spaces and establish a direct correlation between the lavish lifestyles of their landlords and their own unliveable conditions. The performativity of residential buildings during actions emphasises the violence of landlord harassment and forced evictions, turns personal experiences of housing insecurity into public spectacles, and enacts corrections to power imbalances in rental arrangements. More than sites of collective actions, residential spaces provide material evidence of tenant exploitation and a means of visualising tenant power.
Birth weight, slowness in eating and feeding practices as independent determinants of rapid weight gain
Authors: Ortega‐Ramírez Ana Daniela , Murillo‐Zamora Efrén , Trujillo‐Hernández Benjamín , Delgado‐Enciso Iván , Sánchez‐Ramírez Carmen Alicia 
Published: June 2024

AbstractAimOur aim was to identify independent determinants of rapid weight gain in infants at 3‐4, 6, and 12 months of age.MethodsA cohort study was conducted on Mexican term infants in public and private settings between March 2021 and May 2023. Rapid weight gain was defined as a ≥0.67 SD change in weight‐for‐age‐Z‐score from birth to 3‐4, 6, and 12 months of age. Maternal and infant characteristics were described, and infant feeding practices, appetitive traits, weight, and length were analysed at 3‐4, 6, and 12 months of age. Rapid weight gain predictors were determined using generalised linear regression models.ResultsIn total, 168 infants were recruited (55% boys). Small‐for‐gestational‐age status increased rapid weight gain risk 1.5 times, whereas large‐for‐gestational‐age status represented a 20%–30% decrease. Slowness in eating decreased the risk by 10%. Protective factors were older maternal age and higher educational level, whereas formula feeding, early complementary feeding, greater food enjoyment, and satiety responsiveness increased the risk.ConclusionsSmall for gestational age, slowness in eating, and feeding practices can be rapid weight gain predictors across the first year of life.
