Abstract Recent research at the University of Leeds has concentrated on the role of product models in a design and manufacturing environment. This paper describes initial progress in a project developing a data model that can support applications requiring assembly information throughout a product’s life-cycle. Research by other groups worldwide have used sets of mating conditions to describe the physical connectivity between components in an assembly. However these mating conditions are usually application specific. Experiments have been conducted at Leeds to determine whether these previously reported approaches can form the basis for a set of mating conditions which can be represented in a Product Model from which many applications can draw. The experiments were performed by modelling the relationships between components of a shaft mounted speed reducer by 1) using a set of mating conditions and 2) describing the constraints on the degrees of freedom between pairs of components. The perceived shortcomings of these approaches are discussed.

Abstract Product models come from the analysis of the data requirements to support the design and manufacture of products. These models are implemented in databases aimed at providing information to software applications that assist the concurrent design of products. This paper presents the requirements of a data model driven software system to aid the design of injection moulds and analyses two product models which were developed in different contexts but capable of representing injection moulded parts and moulds. A case study is used to show the application of each one of the models selected. Finally, some conclusions of the analysis are drawn in order to set the foundation of a new model.

As part of the National Shipbuilding Research Program (NSRP) program, various tools and standards have been developed to enable the efficient exchange of product models during the design process. In particular, the Integrated Shipbuilding Environment (ISE) Project has developed and demonstrated the capability for successful transfer of structural, piping, and heating, ventilation, and air-conditioning (HVAC) product models that could be used in detail design. During 2005, NSRP awarded a project for ISE Interoperability Modules (known as ISE4). This project will expand the testing and implementation of ISE tools to support both early-stage design and manufacturing efforts. An international standard (ISO 10303-215: Application Protocol— Ship Arrangement) will be used to exchange product model information during early-stage design. Another task in this project, entitled Steel Processing, will focus on using ISE tools and the Standard for the Exchange of Product Model Data (STEP) Standard to define a shipbuilding product model format that will support the requirements of multiple, disparate manufacturing processes. The ISE4 Project also includes tasks to enhance interoperability by providing exchange capabilities for engineering analysis and electrical data. This paper and presentation will show how these new ISE tools will facilitate the exchange of ship product models to support interoperability from early-stage design (using ship arrangements) through manufacture.

Nowadays, the Industry 4.0 concept affects every area of the industrial, economic, social and personal sectors. The most significant changings are the automation and the digitalization. This is also true for the material handling processes, where the handling systems use more and more automated machines; planning, operation and optimization of different logistic processes are based on many digital data collected from the material flow process. However, new methods and devices require new solutions which define new research directions. In this paper we describe the state of the art of the material handling researches and draw the role of the UMi-TWINN partner institutes in these fields. As a result of this H2020 EU project, scientific excellence of the University of Miskolc can be increased and new research activities will be started.

Accurate pronunciation has a vital role in English language learning as it can help learners to avoid misunderstanding in communication. However, EFL learners in many contexts, especially at the University of Phan Thiet, still encounter many difficulties in pronouncing English correctly. Therefore, this study endeavors to explore English-majored students’ perceptions towards the role of pronunciation in English language learning and examine their pronunciation practicing strategies (PPS). It involved 155 English-majored students at the University of Phan Thiet who answered closed-ended questionnaires and 18 English-majored students who participated in semi-structured interviews. The findings revealed that students strongly believed in the important role of pronunciation in English language learning; however, they sometimes employed PPS for their pronunciation improvement. Furthermore, the results showed that participants tended to use naturalistic practicing strategies and formal practicing strategies with sounds, but they overlooked strategies such as asking for help and cooperating with peers. Such findings could contribute further to the understanding of how students perceive the role of pronunciation and their PPS use in the research’s context and other similar ones.

As universities in Australia are faced with a growth in diversity and intensity of religion and spirituality on campus, this article explores the work of chaplains and its reception by students on a multi-campus suburban university. It finds that the religious work of these professionals is not the primary emphasis in the university context; what is of greater significance to students and the university institution is the broader pastoral and welfare-support role of chaplains. We discuss these findings in relation to post-secularism theory and the scaling down of state-provided welfare in public institutions such as universities.

Earlier this year, I received a small grant from the Edinburgh University Development Trust Fund to determine the feasibility of formulating a major research project exploring the religious dimensions within the recent land resettlement programme in Zimbabwe. Since spirit mediums had played such an important role in the first Shona uprising in 1896–97 against colonial occu¬pation (the so-called First Chimurenga) (Parsons, 1985: 50-51) and again in the war of liberation between 1972 and 1979 (the Second Chimurenga) (Lan, 1985), I suspected that these central points of contact between the spirit world and the living communities would be affecting the sometimes militant invasions of white commercial farms that began sporadically in 1998, but became systematic after the constitutional referendum of February 2000. Under the terms of the grant, I went with my colleague, Tabona Shoko of the University of Zimbabwe, in July and August 2004, to two regions of Zimbabwe: Mount Darwin in the northeast, where recent activities by war veterans and spirit mediums had been reported, and to the Mberengwa District, where land resettlement programmes have been widespread. This article reports on my preliminary findings in Mount Darwin, where I sought to determine if evidence could be found to link the role of Traditional Religion, particularly through spirit mediums, to the current land redistribution programme, and, if so, whether increasing levels of political intolerance within Zimbabwean society could be blamed, in part at least, on these customary beliefs and practices

The purpose of this research is to explain the importance of the student organizations and describe their efforts to improve the speaking skills of students at the Mahad Khalid Bin Al Waleed at the University of Muhammadiyah Mataram. This research uses the qualitative approach with the descriptive type. The result shows the student organizations play an important role based on their objectives and functions. The objectives are to help the foundation and all parties in the Ma'had develop the students’ potential and qualification, and to be the place for the students to share their problems and complaints, while the functions are as one of the media to develop students’ quality, both the members of the non-member, and as the good examples and pioneers of any good deeds. The efforts done by student organizations in improving speaking skills are such as by making activities that lead to improving students' speaking skills like sticking vocabularies in each class and Friday activities such as language game, Arabic debate and short lecture.

As members of the secret Afrikaner organisation, the Broederbond, two of the apartheid-era rectors at the University of Fort Hare were responsible for leading an institution that was supposed to spearhead the modernisation of ethnically defined homelands and their transition to independent states, whilst disseminating apartheid values among the black students. Based on unsorted and unarchived documents located in the personal files of the apartheid-era rectors, which included secret correspondence and memoranda of clandestine meetings, this paper illustrates the attempted exercise of hegemony by the apartheid state through its linked network with the university administration during the period 1960 to 1990. This is achieved by demonstrating the interaction between the state, Broederbond rectors and the black students at Fort Hare, who were subjected to persuasion and coercion as dictated by the state’s apartheid vision of a racially defined and separated society.

Information and communications technologies (ICTs) and the Internet have to a large extent influenced the way information is made available, published and accessed. More information is being produced too frequently and information users now require certain skills to sift through this multitude in order to identify what is appropriate for their purposes. Computer and information skills have become a necessity for all academic programmes. As libraries subscribe to databases and other peer-reviewed content (print and electronic), it is important that users are also made aware of such sources and their importance. The purpose of this study was to examine the teaching of information literacy (IL) in universities in Zimbabwe and South Africa, and the role played by librarians in creating information literate graduates. This was done by examining whether such IL programmes were prioritised, their content and how frequently they were reviewed. An electronic questionnaire was distributed to 12 university libraries in Zimbabwe and 21 in South Africa. A total of 25 questionnaires were returned. The findings revealed that IL was being taught in universities library and non-library staff, was compulsory and contributed to the term mark in some institutions. The study also revealed that 44 per cent of the total respondents indicated that the libraries were collaborating with departments and faculty in implementing IL programmes in universities. The study recommends that IL should be an integral part of the university programmes in order to promote the use of databases and to guide students on ethical issues of information use.
