Reliability plays an important role in the execution of the maintenance improvement and the understanding of its concepts is essential to predict the type of maintenance according to the equipment state. Thereby, a computational tool was developed and programming with VBA in Excel® for reliability and failure analysis in a mining context. The paper aims to discuss these issues.

The developed approach use the modeling of stochastic processes, such as the renewal process, the non-homogeneous Poisson process and less conventional method as the Bayesian approach, by considering Jeffreys non-informative prior. The resolution gives the best associated model, the parameters estimation, the mean time between failure and the reliability estimate. This approach is validated with the reliability analysis of inter-failure times from underground rock bolters subsystems, over a two-year period.

Results show that Weibull and lognormal probability distribution fit to the most subsystems inter-failure times. The study revealed that the bolting head, the rock drill, the screen handler, the electric/electronic system, the hydraulic system, the drilling feeder and the structural consume the most repair frequency. The hydraulic and electric/electronic subsystems represent the lowest reliability after 50 operation hours.

For the first time, this case study defines practical failures and reliability information for rock bolter subsystems based on real operation data. This paper is useful to the comparative evaluation of rock bolter by detecting the weakest elements and understanding failure patterns in the individual observation subsystems on the overall machine performance.

Taxing tobacco is one of the most effective means to reduce smoking but concerns about the impact on poor smokers are a barrier. New Zealand resumed increasing tobacco taxes in April 2010. The paper hypothesised smokers would attempt to stop smoking and/or adapt, changing their smoking behaviours in response to price increases. The paper aims to discuss these issues.

The authors conducted a door knock survey of smokers and recent ex-smokers who were home when visited. Participants (n=428) were from socioeconomically deprived neighbourhoods of Auckland with large proportions of Māori and Pacific Island people.

Many smokers (66 per cent) attempted to quit an average of 3 times. More than 40 per cent stopped for at least 24 hours without intending to quit altogether, monthly or more. Consumption reduced among 40 per cent of participants, by an average 7.1 cigarettes daily. More than a fifth of participants switched to cheaper brands. Switching from factory made cigarettes to roll your own tobacco (6 per cent) or vice versa (5 per cent) was uncommon.

The method resulted in a low response rate. Tobacco tax is associated with reduced consumption and high levels of frequent quit attempts in socioeconomically deprived communities therefore our study supports tax increases as a means of reducing smoking.

This is the first paper to investigate the effect of large recent New Zealand tobacco tax increases on low-income smokers’ adaptive behaviours.

Based on a case study in Hamilton, Ontario, Canada, the purpose of this paper is to explore the difficulties faced by local health care providers in the face of constantly evolving refugee policies, programs, and arrivals. In doing so, it illustrates the complications faced by service providers in providing care to refugee arrivals and how the diversity of arrivals challenges health care provision and ultimately the health and well-being of refugees.

A series of semi-structured, in-depth interviews with key service professionals in both the social service and health fields in Hamilton, Ontario, Canada, examined both health and health care issues.

Beyond challenges for service providers that have been previously flagged in the literature, including language barriers and the limited time that they have with their clients, analysis revealed that health care providers faced other challenges in providing care, with one challenge reflecting the difficulty of providing care and services to a diverse refugee population. A second challenge reflected the lack of knowledge associated with constantly evolving policies and programs. Both challenges potentially limit the abilities of care providers.

On-going changes to refugee and health care policy, along with the diversity of refugee arrivals, will continue to challenge providers. The challenge, therefore, for health care providers and policy makers alike is how to ensure adequate service provision for new arrivals.

The Federal government should do a better job in disseminating the impact of policy changes and should streamline programs. This is particularly relevant given limited budgets and resources, tri-partite government funding, short time-frames to prepare for new arrivals, inadequate background information, barriers/challenges or inequitable criteria for access to health and social services, while addressing an increasingly diverse and complex population.

The research reinforces the complexity of the needs and challenges faced by refugees when health is considered, and the difficulty in providing care to this group.

While there is a large refugee health literature, there is relatively little attention to the challenges and difficulties faced by service providers in addressing the health needs of the diverse refugee population, a topic that is particularly important given limited funding envelopes, shifting policies and programs, and a focus on clients (refugees). It is this latter piece – the challenges faced by providers in providing care to refugees – which this paper explores.

The purpose of this study is to utilize an exploratory multiple-case design research method using three undergraduate management courses at a medium-sized private comprehensive college near a large metropolitan area in the USA.

This paper explores differentiated instruction in relation to experiential learning in management education by examining three teaching applications from different management courses to illustrate these concepts.

The use of differentiated instruction in management education is supported through varied approaches such as individual student and team-based scaffolding that demonstrate the applicability of differentiation. In addition to improving student learning, other benefits include improved student retention and faculty autonomy in course creation and delivery. The implementation involves a proactive response to learner needs informed by a faculty perspective that recognizes student diversity yet retains quality assurance standards with mindful assessment and planning.

The comparatively small number of courses and instructional methods may make the specific findings and examples more relevant to the type of institution examined. Yet, the general conclusions and methods identified have potential implications for learners in a wide variety of colleges and universities.

Differentiated instruction may be a useful approach for enhancing learning in heterogenous groups of students by recognizing student readiness and making appropriate modifications.

This paper offers an exploratory overview of differentiated instruction with guidance for management faculty members in designing and implementing these approaches in their courses.

The purpose of this paper is to analyse the steps taken to produce new kinds of integrated documentation on the Holocaust in the European Holocaust Research Infrastructure project. The authors present the user investigation methodology as well as the novel data design to support this complex field.

The paper is based on the scholarly primitives framework. From here, it proceeds with two empirical studies of Holocaust archival research and the implementation steps taken. The paper employs key insights from large technology studies in how to organise such work. In particular, it uses the concepts of social-technical assemblages and intermediation.

The paper offers a number of findings. First from the empirical studies, it presents how Holocaust researchers and archivist perceive the way they currently do research in archives. It then presents how the intermediation and digital transformation of such research can be enabled without violating its foundations. The second major insight is the technical research into how to use graph databases to integrate heterogeneous research collections and the analysis opportunities behind.

The paper is based on existing work by the authors but takes this work forward into the world of real-life existing historical research on archives. It demonstrates how the theoretical foundations of primitives are fit for purpose. The paper presents a completely new approach on how to (re)organise archives as research infrastructures and offers a flexible way of implementing this. Next to these major insights, a range of new solutions are presented how to arrange the socio-technical assemblages of research infrastructures.

The purpose of this paper is to use entrepreneurship to bridge the traditional-progressive education rift.

The rift between traditional and progressive education is first deconstructed into five dualisms. Conceptual question-based analysis is then applied to determine if and how three entrepreneurial tools could contribute to bridging this rift; effectuation, customer development and appreciative inquiry. Finally, pattern-based generalizations are drawn from this analysis.

Patterns in the analysis motivate the articulation of an overarching educational philosophy – learning-through-creating-value-for-others – grounded in entrepreneurship and capable of bridging the educational rift.

Only three entrepreneurial tools are included in the conceptual analysis, signifying a need to explore whether other tools could also help teachers bridge the traditional-progressive education rift. Entrepreneurial tools and the new educational philosophy manifesting entrepreneurship could also need to be further contextualized in order to be useful in education.

The tentatively new educational philosophy has been shown to be capable of bridging five dualisms in education which are currently problematic for teachers in their daily practice, and to remedy teacher challenges such as complexity, lack of resources, assessment difficulties and student disengagement.

An educational philosophy grounded in entrepreneurship has arguably not been proposed previously. Contrasting existent educational philosophies, this new philosophy goes beyond learning-through to also emphasize creating-value-for-others. This could facilitate bridging between traditional and progressive education, one of the most important challenges in education. It could also be used to facilitate the infusion of entrepreneurship into general education.

HIS holidays over, before the individual and strenuous winter work of his library begins, the wise librarian concentrates for a few weeks on the Annual Meeting of the Library Association. This year the event is of unusual character and of great interest. Fifty years of public service on the part of devoted workers are to be commemorated, and there could be no more fitting place for the commemoration than Edinburgh. It is a special meeting, too, in that for the first time for many years the Library Association gathering will take a really international complexion. If some too exacting critics are forward to say that we have invited a very large number of foreign guests to come to hear themselves talk, we may reply that we want to hear them. There is a higher significance in the occasion than may appear on the surface—for an effort is to be made in the direction of international co‐operation. In spite of the excellent work of the various international schools, we are still insular. Now that the seas are open and a trip to America costs little more than one to (say) Italy, we hope that the way grows clearer to an almost universal co‐working amongst libraries. It is overdue. May our overseas guests find a real atmosphere of welcome, hospitality and friendship amongst us this memorable September!
