Abstract ADNOC (Abu Dhabi National Oil Company) recently drilled some wells in Onshore Abu Dhabi (Field-A) and encountered consistent hole instability from Umm Er Radhuma (UER) to Simsima. Thus, a GeoMechanical review was proposed to investigate the root causes, if any, and recommend possible remedies for the upcoming drilling campaign. While detailed drilling event analysis allowed to investigate the correlation between the mud weight program and well trajectory, borehole image log analysis and geological understanding from nearby fields indicated the possible role of structural and lithological features on hole instability. Integration of drilling engineering data and regional geological knowledge helped to narrow down the possible causes of drilling challenges. Sedimentalogical review of Image logs have established some correlation between rock types and hole instability events. Drilling experience shows there is very narrow margin for loss and/or gain to occur. There is regional geological evidence of the presence of a wide range of vuggy structures, as well as natural fractures and/or faults. These features tend to make Simsima formation heterogeneous in terms of permeability and more prone to losses. Since most fractures are parallel to SHmax direction and well was drilled towards Shmin direction, there are greater chances of encountering faults and/or fractures, which would be critically-stressed and lead to loss and/or gain situations. Geomechanical parameters helped highlight the magnitudes and orientations of principal stresses. Observations of several tight hole and stuck pipe events while tripping from Radhuma and UERB shale to Simsima seem to indicate mud weight used was insufficient. Role of multiple failure mechanisms was identified, and relevant solutions were recommended as well as implemented to achieve the drilling success. The case study presented here emphasizes how different carbonate textures and the presence and orientation of natural fractures and/or faults within Simsima formation can impact hole instability with respect to wellbore trajectory. Proactive implementation of recommendations from this analysis on well planning and fluid design resulted in improvement of drilling performance and reduction of non-productive time in new wells.

This paper explores the development of professional understanding across a large group of professionals and academics from eight different countries engaged in an international project. The focus of the project was to develop a suite of appropriate electronic tools to support the wide range of professionals (doctors, teachers, care and family workers, psychologists and medical and occupational therapists) who may be involved in working with and providing support for vulnerable children and families, which would be relevant across European countries. This case study explores how effective communication developed between the members of the research group to enable greater common understanding of both cultural and country specific provision, needs, and the underpinning philosophy and principles behind current provision in different countries represented. It explores the role of a ‘learning community’ and a ‘community of practice’ (Lave & Wenger, 1998) in this process as a tool for developing understanding. It provides insights into related issues, and possible future lessons to be learnt.

SummaryThe radical concept of potato production from true potato seed (TPS) was adopted as a component of their farming system within three seasons by 23 farmers from Cibodas, West Java. The farmers showed an ability to conceptualize and experiment and desired concepts from which they could develop, through research, appropriate principles and field techniques. Information received solely as detailed practices or techniques hindered their progress, since they first needed to repeat the technique in order to understand the concepts and principles involved. Farmer experimentation resembled closely that of experimental station researchers, with the use of replication in space, often neighbouring farmers' plots, and time. Initial experiments covered a wide range of factors but within three seasons farmers had identified similar areas of concern which coincided with those of experiment station researchers worldwide. Farmer experimentation and the role of the researcher in this methodology for technology development are discussed.

This paper examines the complex interaction between island histories and island geographies by presenting a case study of Dongzhou Island, Hengyang, China, contextualized through several critical island events. Employing a wide range of methods including archival research, textual and media analysis, field and map observations, semi-structured interviews, and informal interaction, the research is broadly framed in the problematic of geographical memory consisting of hard island memory, soft island memory, and lived island memory. Particular attention is paid to the construction of Dongzhou Island’s cultural trauma based on three difficult island histories: mass killing, radical planning, and uneven development. Findings indicate that these memories coexist on or about the island, in virtual isolation from each other. It is argued that while hard memory constructs the island as a petrified landmark, soft memories murmur about the forgotten or obscured pains of a small island that bears witness to the violence of war and progress. The theoretical and practical implications regarding the role of place memory in rejuvenating local cultures are also proposed.

Subject area HRM; recruitment; managing cultural expectations in business; leadership. Study level/applicability Undergraduate management courses; MBA and MSc. Case overview This case focuses on recruitment problems in Europe with an Asian dimension. A young Dutch and a young Chinese graduate are considering a career with postal, courier and logistics firm TNT – what are their concerns as graduating students in looking for a job? From the opposite perspective, the case considers how employers attract graduate recruits. The case encourages students of a wide range of cultural backgrounds to question if they are following their cultural norms, or their own personal needs, regardless of their culture. It introduces students to the concept of perceptions of employer value propositions (EVPs) and how employers can “market” themselves to employees. The case is appropriate for courses in leadership, human resource management, corporate social responsibility (CSR), managing culture, also job hunting and career workshops. Expected learning outcomes This case is aimed at projecting the importance of career choice criteria from both graduate and employer perspectives. The case examines issues of national culture and associated differences in employee and organizational expectations. The case also examines the role of CSR in attracting employees; and the particular concerns of Generation Y employees. Supplementary materials Teaching note.

Within many coordinated market economies, labour unions have demonstrated to be key actors in shaping corporate social responsibility. Researchers have, however, paid surprisingly little attention to the role of unions in shaping corporate social responsibility strategies and responses in liberal market contexts. This article extends the emerging research on unions and corporate social responsibility through a case study which investigates union influences over corporate social responsibility within the liberal market context of Australia. We conceptualise the role of unions in corporate social responsibility in this context through an industrial relations lens with particular reference to collective bargaining. Drawing on qualitative data, the case study examines the Ford Motor Company’s recent closure of its Australian assembly operations which was hailed by a wide range of stakeholders as an exemplar of ‘best practice’ in their assistance of displaced workers. We conclude that, while highly socially responsible, Ford’s actions were far from voluntary but influenced by a combination of union influence and a ‘subsidised’ corporate social responsibility, where the state, unable and/or powerless to legislate good corporate social behaviour, chose to financially underwrite its cost to the firm. The study represents one of the first studies to demonstrate how unions shape corporate social responsibility strategies of firms in liberal market contexts and how ‘subsidised’ corporate social responsibility becomes an alternative political solution within such a context.

Universities play an important role in society. On the other hand, more and more governments and international organizations are concerned about the environment. Thus, both in their educational programs and research, as well as in the case of public exhibitions, universities are increasingly including subjects related to the environment and its preservation. In the case of Spain, there are fewer university students than ten years ago (from approximately 140,000 to fewer than 130,000), and the number of students interested in technical and scientific degrees has equally decreased. Consequently, the importance of fostering a scientific culture with concerns in environmental issues is continuously increasing, from schools to universities. The role of real scientific environments, such as laboratories devoted to scientific research, could be an important support for environmental divulgation, as most research carried out at universities have to do with these subjects. The aim of this work was to show a specific case of environmental education in a laboratory devoted to the production of biodiesel and biolubricants, covering a wide range of academic levels and, depending on the audience, selecting the right content (both theoretical and practical). This guide was useful for the laboratory technicians, increasing the interest of the audience (considering the expositions good or excellent, depending on the academic level, and gaining enough or excellent knowledge about biorefineries).
