Abstract

Purpose

To improve the position tracking efficiency of the upper-limb rehabilitation robot for stroke hemiplegia patients, the optimization Learning rate of the membership function based on the fuzzy impedance controller of the rehabilitation robot is propose.

Design/methodology/approach

First, the impaired limb’s damping and stiffness parameters for evaluating its physical recovery condition are online estimated by using weighted least squares method based on recursive algorithm. Second, the fuzzy impedance control with the rule has been designed with the optimal impedance parameters. Finally, the membership function learning rate online optimization strategy based on Takagi-Sugeno (TS) fuzzy impedance model was proposed to improve the position tracking speed of fuzzy impedance control.

Findings

This method provides a solution for improving the membership function learning rate of the fuzzy impedance controller of the upper limb rehabilitation robot. Compared with traditional TS fuzzy impedance controller in position control, the improved TS fuzzy impedance controller has reduced the overshoot stability time by 0.025 s, and the position error caused by simulating the thrust interference of the impaired limb has been reduced by 8.4%. This fact is verified by simulation and test.

Originality/value

The TS fuzzy impedance controller based on membership function online optimization learning strategy can effectively optimize control parameters and improve the position tracking speed of upper limb rehabilitation robots. This controller improves the auxiliary rehabilitation efficiency of the upper limb rehabilitation robot and ensures the stability of auxiliary rehabilitation training.

Abstract

Purpose

As the subject of female criminology in South Africa has only recently been dealt with in a qualitative manner, this paper aims to explore if there is a potential link between rehabilitation, reintegration support and recidivism as females are often placed back into the environment which prompted their criminal behaviour, further excluding them from rehabilitative reform, which might lead them to recidivate.

Design/methodology/approach

The research adopted a qualitative approach using in-depth, semi-structured interviews with six participants that were chosen purposively.

Findings

The paper notes a potential link between rehabilitation, reintegration support and recidivism as the female prisoners are imprinted with criminal dispositions since rehabilitation within the correctional facility has no implementation process to ensure that restoration can continue after they have been released.

Research limitations/implications

Due to the limited number of the incarcerated female population and the scope of the preliminary study, the sample comprised of only six female offenders. As such, it contributes to the larger discourse of female criminality, but does not offer any recommendations.

Practical implications

Provides an understanding of the conditions in which the females are released. Allows for the inclusion of the female’s voice on, and reflection of, rehabilitation and recidivism. Notes a link between rehabilitation, reintegration and recidivism. Creates a pathway for further research in the exploration of a gendered reform approach.

Originality/value

While the subject of female criminology in South Africa has only recently been dealt with in a qualitative manner, this study offers an insight into how females who offend are often placed back into the environment which prompted their criminal behaviour.

Abstract

Purpose

This paper aims to trace Tata Group’s role in responding to disability in the decades immediately following India’s independence until the preliberalization period of the Indian economy, i.e. from the 1950s to the 1990s.

Design/methodology/approach

This study’s methodology entailed a historiographical approach and archival engagement at Tata Archives (Pune, India) of the company documents. Materials and records of the Tata Company between 1942 and 1992.

Findings

Adopting the corporate culture lens, the study findings show that Tata Group demonstrated an active prosocial corporate approach toward disability. In a period governed by the ideology of a state-dominated developmental approach, Tata Group’s initiatives were related to medical interventions for a wide spectrum of disabilities, rehabilitation and efforts to ensure persons with disabilities (PWDS)’ livelihood.

Originality/value

Disability, in the neoliberalized economic landscape of India, is an emergent business issue for companies espousing workplace diversity. The historical understanding of business engagement with disability from postindependence to liberalization in India remains, however, limited. In postindependence India, the passive business response to disability emerged within an ethical and discretionary framework, with charity and philanthropy as the main modes of engagement. In this background, this paper explores Tata’s response to disability and PWDs, which was distinct.

Abstract

Purpose

Social determinants of stressful events (SE) play an important role in justifying the cause of inequality in the experience of SE. The purpose of this study is to investigate the determinants that impact on inequality in the experience of SE.

Design/methodology/approach

The statistical population of this study includes all residents of Tehran. The statistical sample was 5,895 people who were selected by multistage cluster method and were proportional to the population size. The research tool is a researcher-made questionnaire designed to measure SE in Tehran, which includes 11 psychological stressors. The Oaxaca–Blinder decomposing method was used to analyze data.

Findings

In a total of 11 psychological SE, in 6 of those events, there was significant inequality in the experience of SE. Concentration Index (CI) of political SE is (CI = −0.27, 95% CI: −0.47, −0.07) and in favor of the rich (pro-rich). Education (OR = 1.60) in poor group and region development in poor and rich (respectively in all of the following) (OR = 0.42–0.73) are the main determinants of inequality in this stressor. CI of neighborhood underdevelopment SE is (CI = −0.47, 95% CI: 0.66, −0.28) and pro-rich. Education (OR = 1.26–1.27) and region development (OR = 1.18–2.24) are the main determinants of inequality in this stressor. CI of livelihood problems SE is (CI = −0.58, 95% CI: 0.68, −0.32) and pro-rich. Education (OR = 1.40) and health status (OR = 1.63) in poor group are the main determinants of inequality in this stressor. CI of future uncertainty SE is (CI = −0.12, 95% CI: 0.34, −0.08) and pro-rich. Gender (OR = 1.22) in poor group and region development (OR = 0.24–0.58) are the main determinants of inequality in this stressor. CI of education problems (CI = 0.19, 95% CI: 0.05, 0.32) and pro-poor. Age (OR = 0.32–0.34) and education (OR = 3.65–3.30) are the main determinants of inequality in this stressor. CI of housing problems is (CI = −0.29, 95% CI: −0.49, −0.08) and pro-rich. Education (OR = 1.31) and region development (OR = 1.64) in poor group are the main determinants of inequality in this stressor.

Research limitations/implications

The first limitation is related to the level of data analysis, and the second limitation is the lack of comprehensive data on social determinants.

Practical implications

Social determinants affecting the formation of inequality in the experience of SE. Some social determinants, such as the level of education and development of the region, play a more prominent role in justifying inequality in the experience of stress between rich and poor groups.

Social implications

Inequality in the experience of SE is a serious threat to mental and social health. One of the ways to reduce the experience of psychological and social stress is to pay attention to social determinants that play a role in the formation of stress.

Originality/value

This original paper was conducted by examining the effect of social determinants on the formation of inequality in the experience of stress, which draws the serious attention of policymakers.

Abstract

Purpose

This paper aims to present a case study analysing the reintegration programs of Malaysian violent extremist detainees and prisoners. It explores the ongoing challenges faced by these individuals as they strive to reintegrate and assimilate into society.

Design/methodology/approach

Qualitative data was collected through interviews with 12 violent extremist detainees and prisoners who had successfully reintegrated into society. The life course perspective was used as the analytical framework, and data analysis was conducted using ATLAS.ti.

Findings

The study revealed common challenges faced by the participants in gaining societal acceptance, dealing with stigma and achieving economic stability. The results also highlighted the difficulties of sustaining livelihoods due to heightened vigilance in the surrounding environment.

Research limitations/implications

These findings enhance the understanding of factors influencing successful reintegration of people who were involved in violent extremism into mainstream society.

Practical implications

Government bodies, agencies or organisations and non-governmental organisations can implement these successful factors to prevent any issues of recidivism or resentment towards society.

Originality/value

This research contributes unique insights based on data from individuals who have undergone successful or partial successful reintegration. Detailed academic sharing of such information from a Southeast Asian country such as Malaysia is relatively scarce, given the specific procedures required for accessing such data.

Abstract

Purpose

In ethnographic research, negotiating insider–outsider perspectives is essential in order to get closer to the participants’ lives. By highlighting the importance of empathy and reflexivity, the paper attempts to trace my reflexive navigation as a novice researcher as I enter the field as an outsider. The process of co-creation between the researcher and the participant is mediated by the nuances of the researcher’s identity, thereby shaping the researcher–participant relationship.

Design/methodology/approach

The current study elaborates my journey as a Ph.D. scholar in an ethnographic study of persons with spinal cord injury or amputation. The different themes organised around my personal reflections discuss the various challenges I faced and how I navigated through them.

Findings

The paper reflects on how different aspects of my identity, such as being non-disabled, a female and differences in socioeconomic status shaped the researcher–participant relationship. Additionally, it highlights how I traverse through the blurred worlds of insider–outsider and explore the role of reflexivity and empathy in creating a horizontal researcher–participant relationship.

Originality/value

This reflexive journey offers potential insights into budding researchers who often face dilemmas whether or not it is necessary for qualitative researchers to be members of the population they are studying. The paper also contributes to an understanding around practising reflexivity while working with a sensitive population. It argues researchers to look beyond the insider–outsider debate and utilise reflexivity as a tool for a nonhierarchical researcher–participant relationship.

Abstract

Purpose

To reveal the emotions and information needs expressed by Chinese parents of children with autism spectrum disorder (ASD) in an online forum, and their relationship.

Design/methodology/approach

The 10,062 data were from “Yi Lin”, China’s largest online forum for ASD. Open coding identified parents’ emotions and information needs, and a chi-squared test explored the correlation.

Findings

First, parents’ emotions were categorized into four themes: emotions about coping with their child’s care, emotions about the parents’ own behavior, emotions about social support with other parents and emotions about anticipating the future. Parents’ overall emotions were negative (72.47%), while the tendency of emotions varied among the four themes. Second, five information needs topics were expressed: intervention and training of ASD, parenting experiences, schooling issues, social interaction and support and future development. Different information needs topics contained different themes of emotions. Third, the tendency of emotions and expression of information needs were significantly correlated. Negative emotions had a statistically significant correlation in expression of information needs.

Originality/value

This study reveals the relationship between the emotions and information needs expressed by parents of children with ASD. The ASD forum could develop emotional support modules and functions for parents and facilitate emotional communication between parents.

Abstract

Purpose

Goal setting is a crucial aspect of client-centered practice in occupational therapy (OT) for mental health conditions. However, it remains to be seen how goal-setting has been delivered in mental health, particularly the OT process. The purpose of this scoping review was to explore the nature and extent of goal setting delivered in mental health and informed OT practice.

Design/methodology/approach

The authors followed the guidelines of Arksey and O’Malley (2005) and searched three databases using key search terms: “mental disorder,” “goal setting,” and “occupational therapy” and their synonyms.

Findings

After excluding duplicate records, the authors initially screened 883 records and resulted in 20 records in total after the screening process. Most of the identified articles used goal-setting delivered by both a health professional and a client (n = 14), and focused on people with schizophrenia or schizoaffective disorder (n = 13), but three interventions were delivered by occupational therapists. Further research needs on goal-setting in mental health OT, exploring the reliability and validity of different goal-setting strategies and investigating the effectiveness of goal-setting for promoting behavior change and client engagement across various mental health conditions and settings.

Research limitations/implications

The scoping review has some limitations, such as not investigating the validity and reliability of goal-setting strategies identified, and excluding conference papers and non-English articles.

Originality/value

This scoping review presents a mapping of how goal-setting has been delivered in mental health and informed OT practice. The findings suggest limited research in OT and highlight the need for more studies to address the evidence gap in individualized client-centered OT.

Abstract

Purpose

The outbreak of the COVID-19 pandemic has significantly impacted healthcare systems, presenting unforeseen challenges that necessitated the implementation of change management strategies to adapt to the new contextual conditions. This study aims to analyze organizational changes within the total hip replacement (THR) surgery pathway at multiple levels, including macro, meso and micro. It employs data triangulation from various sources to gauge the complexity of the change process and comprehend how multi-level decision-making influenced an unexpected shift.

Design/methodology/approach

A multicentric, single in-depth case study was conducted using a mixed-methods approach. Data sources included patient-reported outcome measures specific to the THR pathway and carefully structured in-depth interviews administered to managers and clinicians in two healthcare organizations serving the same population.

Findings

Decisions made at the macro level resulted in an overall reduction in surgical activities. Organizational changes at the meso level led to a complete cessation or partial reorganization of activities. Micro-level actions for change and adaptation revealed diverse and fragmented change management strategies.

Practical implications

Organizations with segmented structures may require a robust and structured department for coordinating change management responses to prevent the entire system from becoming stuck in the absorptive phase of change. However, it is important to recognize that absorptive solutions can serve as a starting point for genuine innovations in change management.

Originality/value

The utilization of data triangulation enables the authors to visualize how specific changes implemented in response to the pandemic have influenced the observed outcomes. From a managerial perspective, it provides insights into how future innovations could be introduced.
