Abstract

Purpose

Interprofessional education (IPE) has been highly promoted as a means of enhancing interprofessional practice and thereby having a positive impact on healthcare systems and patient outcomes. Various documents mention that sufficient evidence has been accumulated to demonstrate the effectiveness of IPE, yet it is not completely clear what type of evidence is being alluded to. The objective of this review was to gather evidence about IPE programs that resulted in effective long-term outcomes in healthcare. Secondary outcomes included identification of the types of models that met the success criteria, barriers and facilitators of such successful programs if any.

Design/methodology/approach

A systematic search was conducted in PubMed, Web of Science, CINAHL and Scopus. The review considered studies that targeted undergraduate and postgraduate students among more than one health profession and included those in the English language published between 2010 and end of 2020.

Findings

Five studies have been identified and described in this review. These papers evaluated different IPE programs and models.

Research limitations/implications

1. This systematic review investigated the evidence of the existence of IPE programs and the findings show there is no robust specific evidence of long-term impact on healthcare and on patients' outcomes. 2. The conclusion from this review is that it is still unclear what format constitutes a successful and efficient program. 3. Appropriate longitudinal studies need to be designed to identify the impact of IPE on long-term health outcomes.

Originality/value

Overall, the studies show that although there is an emphasis on practice-based learning, there is no robust specific evidence of long-term impact on healthcare and on patients' outcomes. Appropriate longitudinal studies need to be designed to identify the impact of IPE on long-term health outcomes.

Abstract

Purpose

The architecture, engineering and construction (AEC) industry exists in a dynamic environment and requires several stakeholders to communicate regularly. However, evidence indicates current communication practices fail to meet the requirements of increasingly complex projects. With the advent of Industry 4.0, a trend is noted to create a digital communication environment between stakeholders. Identified as a central technology in Industry 4.0, virtual reality (VR) has the potential to supplement current communication and facilitate the digitization of the AEC industry. This paper aims to explore how VR has been applied and future research directions for communication purpose.

Design/methodology/approach

This research follows a systematic literature assessment methodology to summarize the results of 41 research articles in the last 15 years and outlines the applications of VR in facilitating communication in the AEC domain.

Findings

Relevant VR applications are mainly found in building inspection, facility management, safety training, construction education and design and review. Communication tools and affordance are provided or built in several forms: text-based tools, voice chat tool, visual sharing affordance and avatars. Objective and subjective communication assessments are observed from those publications.

Originality/value

This review contributes to identifying the recent employment areas and future research directions of VR to facilitate communication in the AEC domain. The outcome can be a practical resource to guide both industry professionals and researchers to recognize the potentials of VR and will ultimately facilitate the creation of digital construction environments.

Abstract

Purpose

Damage due to delamination is an important issue during drilling in polymer-matrix composites (PMCs). It depends on thrust force and torque which are functions of feed rate. Transfer function of thrust force with feed rate and torque with feed rate is constructed through experiments. These transfer functions are then combined in state-space to formulate a sixth-order model. Then thrust force and torque are controlled by using optimal controller. The paper aims to discuss these issues.

Design/methodology/approach

A glass fiber reinforced plastic composite is drilled at constant feed rate during experimentation. The corresponding time response of thrust force and torque is recorded. Third-order transfer functions of thrust force with feed rate and torque with feed rate are identified using system identification toolbox of Matlab®. These transfer functions are then converted into sixth-order combined state-space model. Optimal controller is then designed to track given reference trajectories of thrust force/torque during drilling in composite laminate.

Findings

Optimal control is used to simultaneously control thrust force as well as torque during drilling. There is a critical thrust force during drilling below which no delamination occurs. Therefore, critical thrust force profile is used as reference for delamination free drilling. Present controller precisely tracks the critical thrust force profile. Using critical thrust force as reference, high-speed drilling can be done. The controller is capable of precisely tracking arbitrary thrust force and torque profile simultaneously. Findings suggest that the control mechanism is efficient and can be effective in minimizing drilling induced damage in composite laminates.

Originality/value

Simultaneous optimal control of thrust force and torque during drilling in composites is not available in literature. Feed rate corresponding to critical thrust force trajectory which can prevent delamination at fast speed also not available has been presented.

Abstract

Technology provision and Next Generation Learning Spaces (NGLS) should respond to the active learning needs of twenty-first century learners and privilege multiple ‘pictures of learning’ and associated knowledge work. In this sense it is important for NGLS to be pedagogically agnostic – agile enough to cater for a range of pedagogical approaches within the one physical space. In this chapter, the democratising and potentially disruptive power of new digital technologies to facilitate the privileging of these multiple pictures of learning is explored, recognising the significant rise in student ownership and academic use of mobile technologies. With their escalating ubiquity and their facilitation of active knowledge work, research around considerations for the implementation of mobile digital technologies is canvassed, highlighting a range of issues to be considered. This is part of the ‘hidden work’ of technology implementation. Without this hidden work, the potential of NGLS in facilitating and privileging active learning and multiple pictures of learning is diminished and the potential for reinforcing already powerful and potentially exclusionary modes of knowledge work increases. Finally to assist in articulating the hidden work of digitally enabled NGLS, a model is proposed to help understand how ease of use and confidence impacts on student and academic knowledge work.

Abstract

Purpose

Damage induced during drilling of polymer matrix composites depends upon torque during drilling. Modeling of torque with feed rate and its control becomes imminent for damage free drilling of composite laminates. Therefore, the purpose of this paper is to construct a transfer function between drilling torque and feed rate based upon experiments. Thereafter, the torque is controlled by using PID controller.

Design/methodology/approach

This paper presents step-by-step procedure to capture complex drilling dynamics of polymer matrix composites in a mathematical model. A glass fiber reinforced plastic (GFRP) composite laminate is drilled at constant feed rate during experimentation. The corresponding time response of torque is recorded. First order, second order and third order transfer functions between torque and feed rate are identified using system identification toolbox of Matlab®. These transfer functions are then converted into state-space models. Experimental verification is performed on GFRP composite laminate. PID controller is designed using Simulink® to track a given reference torque during drilling of polymer matrix composite. The controller is then validated using different reference torque trajectories.

Findings

Good match is observed between torque response from state-space models and experiments. Error analysis based on integral absolute error and integral squared error on experimental and simulated response show that third-order system represents the complex drilling dynamics in a better way than first and second-order systems. PID controller effectively tracks given reference trajectories.

Originality/value

Third-order model between torque and feed rate for drilling of composites not available in literature has been presented. PID controller has previously been applied successfully for drilling of conventional materials, this paper extends implementation of PID torque control for drilling of composites.
