Abstract
Pitching workpieces can significantly reduce the cycle time of industrial robots and extend their workspace. A control method for pitching workpieces by cylindrical coordinate type robots is developed and can be readily implemented by a computer program technique which calculates the minimum time that a robot must hold a workpiece before it is pitched to a target. For a given target location, the robot programmer supplies data to the program about the initial position of the arm and the robot's vertical, extension and rotational velocities. The outputs are the release position coordinates and the release velocity components associated with the minimum handling time. This information is used to set the controls on an industrial robot. If the workpiece receptacle location is adjustable, vertical heights of horizontal target planes are entered as input. Plots are then generated of minimum handling times for each selected target plane. This information and a knowledge of workpiece constraints helps a robot programmer select a workpiece receptacle location with the shortest possible minimum handling time.

Abstract
The visual instruction software system was designed with typical industrial situations serving as guidelines. The programmer is assumed to have little knowledge of computers. Rather, he is expected to have a detailed knowledge of the task to be performed. The V/I system provides a safe and simple means to communicate this knowledge to the robot control computer. The design of a software system for programming industrial robots is presented. This software system allows the robot's task to be described through visual means. Television cameras and hand‐held arrays of small lights permit the time spent in programming a robot to be radically reduced. Programmers need only place an array of lights in the robot's field of view and press a button on a hand‐held keyboard to specify robot hand position and orientation. Hence, time delays usually encountered when co‐ordinating the movement of robot arm joints are eliminated.

This paper aims to introduce and identify a new 3D handling operation (bin picking) for natural discrete food products using food categorisation.
Abstract
Purpose
This paper aims to introduce and identify a new 3D handling operation (bin picking) for natural discrete food products using food categorisation.
Design/methodology/approach
The research shows a new food categorisation and the relation between food ordering processes and food categories. Bin picking in the food industry needs more flexible vision software compared to the manufacturing industry in order to decrease the degree of disarray of food products and transfer them into structure.
Findings
It has been shown that there are still manual operated ordering processes in food industry such as bin picking; it just needs new ideas of image processing algorithms such as active shape models (ASMs) on its development in order to recognise the highly varying shapes of food products.
Research limitations/implications
This research was aimed at locating a new ordering process and proving a new principle, but for practical implementation this bin picking solution needs to be developed and tested further.
Originality/value
Identifying new ordering processes via food categorisation is unique and applying ASMs to bin picking opens a new industrial sector (food industry) for 3D handling.

Abstract
Purpose
Successive governments have called for greater “empowerment” of the patient, reflected in the chief medical officer's call for more patient‐related outcome measures (PROM). This paper aims to bring together three‐linked studies.
Design/methodology/approach
First study: in 1999, the neurosurgical patient was seen as “expert” to identify PROM outcomes, based upon a patient and carer‐designed self‐administered postal questionnaire in a regional two‐year retrospective survey of subarachnoid haemorrhage (SAH) patients with a 77 per cent response rate, designated treatment‐as‐usual (TAU) cohort (n=142).Second study: in the same region, following the implementing of the specialist neuro‐vascular nurse (SNVN), the SNVN recommendation was evaluated in a two‐year prospective study (n=184) that provided family‐specific psychosocial support and a continuity of care linking hospital and community; the response rate was 87 per cent. Third study: A re‐analysis of the national SAH study (n=2,380), by projecting the TAU and SNVN results onto clinically matched patients within the National cohort to estimate the potential “savings” if all 34 neurosurgical units had an SNVN type service.
Findings
First study: respondents identified many psychosocial and fiscal problems but recommended a SNVN to reduce these difficulties. Second study: the TAU and SNVN patient's were a close clinical match and using the TAU as a control group, it was found that there were major psychosocial and fiscal benefits for SNVN patients and carers, who more speedily re‐established their lives.Third study: it was estimated that this would have produced major financial benefits, e.g. 4,165 fewer bed occupancy days, saving £2.5million; reduced time‐off work for patients and carers, saving £8.1million; and, after deducting cost of a national SNVN service, a combined saving for the service and families of an estimated £9.83 million p.a. Thus, addressing PROM outcomes, through an integrated psychosocial service in neurosurgery was cost‐effective, benefited families, the service, and the wider economy and should be a factor when considering pressurised departmental budgets.
Originality/value
Overall, what the two regional studies and the re‐analysis of the national study showed was that there are benefits from treating the “patient as expert” and taking on board their agendas. There is a need for a more integrated approach to treatment and care that is of value to the service, patients, families and the wider economy.

Abstract
Gives an in depth view of the strategies pursued by the world’s leading chief executive officers in an attempt to provide guidance to new chief executives of today. Considers the marketing strategies employed, together with the organizational structures used and looks at the universal concepts that can be applied to any product. Uses anecdotal evidence to formulate a number of theories which can be used to compare your company with the best in the world. Presents initial survival strategies and then looks at ways companies can broaden their boundaries through manipulation and choice. Covers a huge variety of case studies and examples together with a substantial question and answer section.

Abstract
Purpose
Internationalisation in higher education (HE) has always been romanticised and idealised but there has been limited focus on the internationalisation of gender equality and Equality, Diversity and Inclusion (EDI) certification and the role of international partnerships. Certification and Award Schemes (CAS), such as the Athena Swan Charter, can promote gender equality, best practices exchanges and foster institutional changes. Nevertheless, simply transferring strategies or frameworks without careful consideration of the nuances of the destination context can inadvertently lead to the perpetuation or exacerbation of gender inequalities and reproduce hierarchical relations between the Global South and North. Brazil's cultural and political context highlights the need for adapting the CAS framework to align with the unique conditions of the country, as well as institutional transformations in order to accommodate such a framework. This study aims to critically explore how gender equality and EDI certification can be internationalised in the Global South and how international partnerships can play a role in this process.
Design/methodology/approach
Building on a collaborative UK–Brazil funded project on advancing gender equality in Brazilian academia, we critically reflect on the assumptions of the funding call for operationalising international collaborations, and how we built solidarity – informed by our positionalities – against underlying colonial patterns. As part of our partnership, we were consulted to provide feedback on the introduction of an Athena SWAN framework in Brazil. We reflect on how the Athena Swan framework was “internationalised” in Brazil, especially in relation to its focus, the challenges of implementing gender equality and EDI efforts and the conditions required for such efforts to be meaningful in the Brazilian context. Thus, we assess and critically reflect on the current situation in Brazil, the role that certification can play for EDI and which conditions are required to enact change. In addition, we reflect on our positionalities and working practices as part of this collaboration as feminist researchers from different disciplinary and geographical backgrounds.
Findings
We trace colonial logics in the operationalisation of the funding scheme on setting international collaborations valorising the UK system and reinforcing geopolitical production of knowledge hierarchies between the Global North and Global South. Furthermore, reflecting on the Brazilian political, cultural context with a focus on HE we find similar challenges – to the UK – in implementing gender and EDI efforts. However, there are particular nuances in the Brazilian context that exacerbate these obstacles and make the implementation of an EDI certification framework in Brazil particularly challenging. Overcoming these barriers requires a collective effort from government, funding bodies, scientific associations and HE institutions, for the implementation of impactful and sustainable initiatives beyond mere rhetoric. Finally, while we had a positive collaboration, we felt ambivalent towards certain dimensions of the way the partnerships and the EDI internationalisation were operationalised.
Practical implications
We provide insights and practical recommendations that enhance the understanding of the issues surrounding the implementation of EDI efforts internationally such as CAS in the Brazilian context.
Social implications
Reflecting on the internationalisation of EDI can lead to more tailored context-sensitive frameworks and activities that have the potential to influence societal attitudes and expectations towards gender roles and inclusivity, contributing to a more equitable and just society at large. It also touches upon the dynamics of international partnerships and collaborations across different contexts that can have implications for how such partnerships should be developed and funded beyond a mainstream colonial approach of “mentoring less advanced institutions”.
Originality/value
We reflect and critically discuss the internationalisation of EDI certification in HE and the role of international collaborations towards this process, a topic that has not been often examined within the literature on the internationalisation of HE as a romanticised and positive discourse. From our experience, we explore how such efforts can bring up ambivalence in the way they are operationalised and have the potential to both reinforce and disrupt colonial hierarchies.

Abstract
Purpose
Aims to show how robots can be used to prototype and prove key handling operations during the design of food processing machines. This can reduce both development time and costs.
Design/methodology/approach
A number of examples of the use of robots during the design of food processing machinery are presented in the areas of product handling, product manipulation and product packing. In each example simple grippers were mounted to robots allowing complex manipulations to be performed and rapidly tested allowing a favourite to identified.
Findings
Finds that robot prototyping and proving allows mechanisms to be assessed rapidly and at low cost and reduces the number of design modifications needed before final production.
Research limitations/implications
Provides examples of how the technique can be used in all stages of food production, particularly the grasping of products considered difficult to handle.
Practical implications
Provides a method of reducing the development cost of new food processing machinery and allow key operations to be proved without the need to construct full prototype machines.
Originality/value
Introduces the concept of using robots to prototype and prove operations found within food processing machinery. The paper is of value to both researches investigating the handling of food products and manufacturers of automation for the food industry.
