Assesses the impact of CD‐ROM on reference information services in Ghanaian libraries via the results of a questionnaire which was sent to ten relevant libraries. The results reveal to what end CD‐ROM is being used, to what extent and to what advantage and disadvantage. Observes that although CD‐ROM appears to be beneficial to reference services, it is also highlighting various problems in information services in general. Also notes the problem of limited user access to CD‐ROM facilities owing to over‐protectiveness and lack of staff training.

This article describes the wide variety of installation standards, conventions and procedures currently maintained by the publishers of CD‐ROMs, and the problems this can cause for the user. It is designed to offer a guide through the pitfalls of CD‐ROM installation, and lists hardware and software requirements for users of IBM PCs and compatibles. It is based on the experience of the author who carried out a survey of CD‐ROMs for the University of Hawaii.

Addresses the problem of sharing a CD‐ROM drive on a local area network, suggesting several products which can be used to overcome these hurdles. Compares two software packages: CD Server and Opti‐Net, noting their similarities and differences. Explains that Macs have no need of specialist software, as they can share CD‐ROMs with just a little preparation. Laments the obstacles of speed of access times, and the time taken to change CDs.

The purpose of this paper is to develop videographic methods for the study of alternative entrepreneurship, with a theoretical focus on “ethical uncertainties”, exemplified in this paper by the exploration of evolving actions and unpredictable outcomes in a specific case, the Hungarian company Prezi.

By first situating Prezi’s alternative entrepreneurship in the turbulent Hungarian political context and situation for the Roma population, this study presents how the methodological foundations of organizational videography have affirmed aesthetic immersion, which is of particular use for the study of ethical uncertainty.

Following a methodological exploration of the specific research design and ethnographic reflections on three ways in which ethical uncertainties arise, this study discusses the videographic possibilities to study something as elusive as ethical uncertainty and its link to alternative futures.

The political context in Hungary poses many challenges for organizations that attempt to “do good” and create alternative futures. This paper explains how this political context permeates Prezi’s entrepreneurship and research thereof, by highlighting “ethical uncertainty”. The combined contribution (paper and videography) invites the reader to think differently about the authority of research, become a viewer and reflect on their own experiences of ethical uncertainty in alternative entrepreneurship.

The purpose of this paper is to explore the emergence of “Roma health and wellbeing” as a focus of attention in European research and in policy and the possible detrimental consequences of action founded on a generic representation of “Roma health.”

Based on discussions with and research conducted by scholars who work directly with Roma communities across European regions from a wide range of academic disciplines it suggests how future research might inform: a more nuanced understanding of the causes of poor health and wellbeing among diverse Roma populations and; actions that may have greater potential to improve the health and wellbeing among these populations.

In summary, the authors promote three types of research: first critical analyses that unpick the implications of current and past representations of “Roma” and “Roma health.” Second, applied participatory research that meaningfully involves people from specific self-defined Roma populations to identify important issues for their health and wellbeing. Third, learning about processes that might impact on the health and wellbeing of Roma populations from research with other populations in similarly excluded situations.

The authors provide a multidisciplinary perspective to inform research that does not perpetuate further alienation and prejudice, but promotes urgent action to redress the social and health injustices experienced by diverse Roma populations across Europe.

This paper aims to present an efficient IMPES algorithm based on a global model order reduction method, proper orthogonal decomposition (POD), to achieve the fast solution and prediction of two-phase flows in porous media.

The key point of the proposed algorithm is to establish an accurate POD reduced-order model (ROM) for two-phase porous flows. To this end, two projection methods including projecting the original governing equations (Method I) and projecting the discrete form of original governing equations (Method II) are respectively applied to construct the POD-ROM, and their distinctions are compared and analyzed in detail. It is found the POD-ROM established by Method I is inapplicable to multiphase porous flows due to its failed introduction of fluid saturation and permeability that locate on the edge of grid cell, which would lead to unphysical results.

By using Method II, an efficient IMPES algorithm that can substantially speed up the simulation of two-phase porous flows is developed based on the POD-ROM. The computational efficiency and numerical accuracy of the proposed algorithm are validated through three numerical examples, and simulation results illustrate that the proposed algorithm displays satisfactory computational speed-up (one to two orders of magnitude) without sacrificing numerical accuracy obviously when comparing to the standard IMPES algorithm that without any acceleration technique. In addition, the determination of POD modes number, the relative errors of wetting phase pressure and saturation, and the influence of POD modes number on the overall performances of the proposed algorithm, are investigated.

1. Two projection methods are applied to establish the POD-ROM for two-phase porous flows and their distinctions are analyzed. The reason why POD-ROM is difficult to be applied to multiphase porous flows is clarified firstly in this study. 2. A highly efficient IMPES algorithm based on the POD-ROM is proposed to accelerate the simulation of two-phase porous flows. 3. Satisfactory computational speed-up (one to two orders of magnitude) and prediction accuracy of the proposed algorithm are observed under different conditions.

The article deals with one of the key causes of Roma children's low academic achievement, notably their presence in segregated special schools originally reserved for mentally disabled children. The purpose of the research was to analyse the assessment process for school‐readiness and special educational needs, and discover the reasons for Roma children's widespread failure on the tests.

Using a quantitative survey and qualitative focus group interviews, the study analysed the assessment process for school‐readiness and special educational needs.

The tests in use offer an overly generalized picture of children's abilities. The test results have little influence on the actual decisions about the schools children will be sent to. Roma children tend to do significantly worse on the tests than non‐Roma children, in all examined areas.

The situation of Roma is similar in all countries of the East and Central European region, and resembles the situation of all socially excluded ethnic minority groups. The results can therefore contribute to a better understanding of the educational situation of Roma and other ethnic minority groups in the region. However, the education system as well as the process of determining special educational needs are in several ways unique in each country. The findings therefore have limited validity outside of Hungary.

Although the problems with Roma children's academic performance are well documented, there had been no research in Hungary that focused on the selection process and the problems of using assessment tests in determining Roma children's special educational needs.

Diversity is the wealth of Montenegro. It is a comparative advantage that provides an exceptional opportunity for understanding and tolerance. It encourages citizens to dialogue, get to know each other and get closer and not to misunderstand, confront and divide society. Any attempt to explore and consider the position of the minority national and ethnic groups in a given social reality is a very specific problem. The best indicator of democracy and tolerance achieved by the social system in a country is the attitude towards its minorities. It is reflected in the majority population's ability to exist under the conditions of tolerating and respecting minorities and their rights. In that sense, the question of the actual (not only constitutional) position of the minorities is an issue of the majority community just as it is a specific mirror of its achieved level of tolerance, emancipation and culture of living. It is especially interesting to explore those national and ethnic minorities with no ‘mother country’, that is, ‘no one to stand up for them’. The Roma population is one of these. It should be kept in mind that its position, regardless of the state in question, is complex and faces various problems.

In order to significantly improve the overall position of the Roma population in Montenegro, it is necessary to improve the socio-economic status of this group. The best way to do such a thing is through the acquisition of new knowledge and skills, as well as the promotion of Roma's identity and cultural heritage. The poor socio-economic status of Roma in Montenegro is a consequence of their inability to be employed. They are not employed because they are not formally educated or do not have a significant level of institutional education. So it is a vicious circle in which the Roma are spinning unsuccessfully to resolve, at least somewhat decently, their socio-economic position. The educational situation of the Roma population in Montenegro is significantly better at the end of the second decade of the twenty-first century, but still not nearly satisfactory in the way how that members of this population successfully participate in finding and getting a job. Therefore, through mutual communication between Roma and other social actors in Montenegro, it is necessary to raise awareness and strengthen the capacity of Roma about the importance of education and the connection of this segment of society with their employment. This leads to the improvement of the overall position of the Roma population in Montenegrin society, as well as the building of an inclusive and open society, a society of equality and justice and equal opportunities for all residents to access educational institutions at various levels and other legal and social structures.

History of the project South Bank Polytechnic Library has been networking CD‐ROM databases since the summer of 1990. John Akeroyd, Head of Library Services at South Bank Polytechnic, initiated the CD‐ROM networking project at the London Road library, the main library within South Bank Polytechnic, after carrying out a British Library research project and visiting the USA where CD‐ROM networking was successfully established in libraries there. He was particularly impressed with the OPTI‐NET software that many libraries were using.
