Ongoing research in computational design synthesis of passive dynamic systems aims to automatically generate robotic configurations based on a given task. However, an automated design-to-fabrication process also requires a flexible fabrication method. This paper aims to explore designing and fabricating passive dynamic walking robots and all necessary components using single-material fused deposition modeling (FDM). Being able to fabricate all components of a robot using FDM is a step toward the goal of automated design and fabrication of passive dynamic robots.

Two different configurations of passive dynamic walking robots are re-designed to be fabricated using FDM. Different robotic joint assemblies are designed and tested. To arrive at feasible solutions, a modular design approach is chosen and adjustability of components after printing is integrated in the design.

The suitability of FDM for printing passive dynamic robots is shown to depend heavily on the sensitivity of the configuration. For one robot configuration, all components are printed in one job and only little assembly is needed after printing. For the second robot configuration, which has a more sensitive gait, a metal bearing is found to increase the performance substantially.

Printable, monolithic mechatronic systems require multi-material printing, including electronics. In contrast, passive dynamic systems not only have the potential to save energy and component cost compared to actuated systems but can also be fabricated using single-material FDM as demonstrated in this paper.

The purpose of this paper is to understand how Design for Additive manufacturing Knowledge has been developing and its significance to both academia and industry.

In this paper, the authors use a bibliometric approach to analyse publications from January 2010 to December 2020 to explore the subject areas, publication outlets, most active authors, geographical distribution of scholarly outputs, collaboration and co-citations at both institutional and geographical levels and outcomes from keywords analysis.

The findings reveal that most knowledge has been developed in DfAM methods, rules and guidelines. This may suggest that designers are trying to learn new ways of harnessing the freedom offered by AM. Furthermore, more knowledge is needed to understand how to tackle the inherent limitations of AM processes. Moreover, DfAM knowledge has thus far been developed mostly by authors in a small number of institutional and geographical clusters, potentially limiting diverse perspectives and synergies from international collaboration which are essential for global knowledge development, for improvement of the quality of DfAM research and for its wider dissemination.

A concise structure of DfAM knowledge areas upon which the bibliometric analysis was conducted has been developed. Furthermore, areas where research is concentrated and those that require further knowledge development are revealed.

Self-harm is a cause of concern for health-care professionals. The Short-Term Assessment of Risk and Treatability (START) is a short-term assessment instrument used to rate the likelihood of risk behaviours, including self-harm. As result of the assessment, interventions that are implemented to reduce the risk of self-harm may reduce the strength of the predictive validity of a risk assessment tool. The aim of this study was explore the impact of risk management interventions on the capacity of START to predict self-harm. It was predicted that the interventions would weaken the ability of START to predict self-harm in patients who received the intervention.

Secondary analysis of routinely collected data in a large sample of women in an inpatient secure care setting. Demographic and clinical information, self-harm episodes, safety management interventions and START assessments were extracted and used to build an anonymous database.

START significantly predicted self-harm in those with and without the safety management intervention. However, the strength of the predictive validity was smaller in those who received the intervention compared to those without.

The results suggest that the implementation of safety management interventions needs to be taken into account when assessing future risk of self-harm.

To the best of the authors’ knowledge, this is the first study to explore the impact of safety management interventions on the predictive validity of START in a large sample of women.

Transition from inpatient mental health care to community living can be very difficult, as people are at an increased risk of suicide, self-harm and ultimately readmission into hospital. There is little research conducted exploring peer support workers’ (PSWs) lived experiences that could provide insight into the key transitions of care, particularly the support required after discharge from inpatient mental health care. The purpose of this paper is thus to provide a particular insight into what it feels like being discharged from psychiatric care from a PSW’s perspective, how may support be improved post-discharge and what factors might impact the potential for readmission into inpatient care.

A qualitative, phenomenological approach was adopted to explore and describe PSWs’ lived experiences of transitioning from psychiatric care. Four PSWs who were employed by a UK secure mental health facility were recruited. PSW is a non-clinical role with their main duty to support patients, and they were considered for this type of the study for their experience in negotiating the discharge process to better carry out their job as a PSW.

After being discharged from psychiatric care, PSWs experienced issues that had either a negative impact on their mental wellbeing or even resulted in their readmission back into inpatient psychiatric care. This study identified three inter-related recurrent themes – continuity of support, having options and realisation, all concerning difficulties in adjusting to independent community life following discharge. The findings of the study highlighted the importance of ensuring that service users should be actively involved in their discharge planning, and the use of effective post-discharge planning processes should be used as a crucial step to avoid readmission.

A deeper insight into the factors that impact on readmission to secure care is needed. The active involvement of service users in effective pre- and post-discharge planning is crucial to avoid readmission.

Mental health professionals should consider developing more effective discharge interventions in collaboration with service users; inpatient services should consider creating more effective post-discharge information care and support packages. Their lived experience empowers PSWs to play a key role in guiding patients in the discharge process.

This is the first study, to the best of the authors’ knowledge, to explore what it feels like being discharged from inpatient mental health care by interviewing PSWs employed at a forensic mental health hospital by adopting a phenomenological approach. This paper offers a deeper insight into the transition process and explores in detail what support is needed post discharge to avoid potential readmission from PSWs’ perspectives.

The purpose of this study is to examine the relationship of sustainability knowledge to pro-environmental behaviour. A common misperception is that unsustainable behaviours are largely driven by a lack of knowledge of the underlying societal costs and the contributing factors leading to environmental degradation. Such a perception assumes if individuals “only knew better” they would engage in more sustainable behaviours. The “knowledge deficit model” has been critiqued for not including social psychological research about how knowledge is incorporated into decision-making and its subsequent effect on human behaviour. The theory of planned behaviour (TPB) model has been used extensively to examine intention to engage in a variety of behaviours, therefore this model is applied to examine the effect knowledge has in predicting behaviour.

To better understand these relationships, the authors examined the relationships between sustainability behaviours through an online survey of over 500 students at a large university in the USA.

Results indicate that knowledge had a significant, albeit weak, bivariate correlation with behaviour (r = 0.113, p < 0.001). However, when controlling for TPB variables (attitudes, norms and perceived behavioural control), knowledge was not a significant predictor of behaviour.

The authors conclude with several implications to guide university sustainability programmes.

This study places sustainable knowledge in the context of other social psychological factors which also influence behaviour. The results show that as the students are educated about sustainability, fostering behaviour change will require education not only about how actions affect sustainability but also about social norms, attitudes towards sustainable behaviours and the level of self-efficacy in doing those behaviours.

Intimate partner violence (IPV) represents a widespread social and public health problem. Researchers have been shown association between IPV and mental health problems. The purpose of this paper is to present a review of the literature on relationship between wide ranges of mental health problems.

Research papers related to mental health problems among IPV perpetrators and published in leading academic journals in UK and abroad from 1987 to 2017 were identified and reviewed.

Although there were some equivocal findings, the authors found that most of the available research suggests that there is a variety of psychological health problems among IPV perpetrators. Specifically, there was evidence of a significant relationship between anger problems, anxiety, depression, suicidal behaviour, personality disorders, alcoholism or problem gambling and perpetration of IPV. Results from analysed studies identified high rates of co-morbid disorders in IPV perpetrators.

The findings highlight the need for treatment services to undertake screening and assessment of wide range of psychological difficulties to be able to provide best treatment approaches.

To the best of our knowledge, this is the first systematic review that has included studies evaluating various psychological health problems among perpetrators of IPV.

This study aims to investigate the effects of leadership competences (cognitive, interpersonal, and results-oriented competences) on organizational learning, organizational innovation, and business performance.

Data were collected from owners, chief executive officers, top and middle management teams, and other managers of tourism and hospitality firms in Vietnam. A total of 638 valid responses was collected and processed using PLS-SEM technique.

The findings revealed that only results-oriented competence exerted significant influences on business performance. Organizational learning was affected by all three leadership competences, while only cognitive and interpersonal competences positively affected organizational innovation. The relationships among organizational learning, organizational innovation, and business performance were also confirmed. Moreover, the findings emphasized the mediating roles of organizational learning and organizational innovation in the relationship between leadership competences and business performance. Organizational learning and organizational innovation also acted as a mediator in the relationship between cognitive competence and business performance.

This study provided some suggestions for tourism and hospitality leaders in exhibiting appropriate leadership competences, strengthening organizational learning, and fostering organization innovation to enhance business performance.

Although the topics of leadership competences, organizational learning, organization innovation, and business performance have received a great concern among worldwide academia, there is scarce research examining the relationships among these four phenomena together. This paper is among the first study that offers a comprehensive model of the relationships among these domains.

This article aims to explore the factors influencing patients' distrust toward doctors in online health community.

This study leveraged the distrust construct model and socio-technical systems theory to establish a research model. The authors used the survey method to validate the research model by developing and distributing questionnaires to online health community users. 518 valid responses were collected.

The data analysis results showed that patients' distrusting beliefs were significantly related to their distrust toward doctors in online health communities. Meanwhile, social factors included perceived egoism and lack of expertise; whereas technical factors included no structural assurance, and lack of third-party recognition.

This study not only provides a solid and comprehensive theoretical understanding of patient distrust toward doctors in online health communities but also could serve as the basis to relieve the distrust between patients and doctors in online health communities, or even in the offline environment.
