The purpose of this paper is to propose a quantitative model for risk-based maintenance and remaining life assessment for gas turbines.

The proposed model uses historical failure and repair data from the operation of gas turbines. The time to failure of gas turbines is modeled using Weibull distribution.

The total risk is estimated considering replacement cost, repair cost, operation cost, risk of failure and turbine remaining value after a specified period of time.

The model is an effective tool to make optimal decisions regarding maintenance strategy (repair or replacement) and to assess the remaining life based on a comparison of the total risk. The literature review focusses on developing different models to make risk-based decisions regarding the selection of a maintenance strategy and maintenance interval, however, literature is silent regarding risk-based assessment of the equipment remaining life, which is the focus of present work. The model is tested and applied to ageing gas turbines in a cross-country pipeline.

The purpose of this paper is to discuss a vibrant social service culture in British and Indian higher education institutions in the period 1905-1919. The paper explores the many reciprocal influences between India and Britain, which lay behind the student social service movement. Developments in metropole and colony were so influenced by transnational movements of people and ideas that the common approaches and shared ideals which emerged cannot be fully understood by study of either setting in isolation.

The paper draws on a rich vein of college magazines and social service league publications as well as the writings of a range of enthusiasts for social service. The rapid spread of social service ideas across India and Britain relied on the exchange of ideas through English-language magazines and journals and the outreach work of leading social servants who addressed numerous student groups and meetings.

Developments in Indian and British student service were shaped by and shaped in turn a wider social movement in the early twentieth century. Indian and western educationalists spread ideas about student social service through lectures, publications and international exchanges. Student social servants in both metropole and colony shared a set of core values which made up an “ideal of service”. Students in both metropole and colony were enjoined to view their education as a period of preparation for greater service to the nation after graduation. Student service leagues were involved in reworking patriotic idiom to link social service with nation building.

The paper builds on recent work on social service and education to develop knowledge and understanding of transnational networks of educationalists, particular movements of people and ideas between colonial India and metropolitan Britain. Taking social service in higher education as a case study, the paper argues for the need to study developments in both metropole and colony in order to better understand reciprocal impacts.

There has been substantial interest in US cesarean rates, which increased from 5% of deliveries in the 1970s to nearly one-third of births by the mid-2000s. Explanations typically emphasize individual risk factors (e.g., advanced maternal age, increased BMI, and greater desire for control over delivery) of women giving birth, or address institutional factors, such as the medicalization of childbirth and the culture of liability leading physicians to practice defensive medicine. We focus here on another non-medical explanation – childbirth education (CBE). CBE is an important, underexplored mechanism that can shape women’s expectations about labor and birth and potentially lead them to expect, or desire, a cesarean delivery as a normalized outcome. We analyze data from three waves (2002, 2006, 2013) of the Listening to Mothers national survey on US women’s childbearing experiences (n = 3,985). Using logistic regression analysis, we examined both mode of delivery (vaginal versus cesarean), and attitudes about future request for elective cesarean among both primiparous and multiparous women. Despite previous research suggesting that CBE increased the likelihood of vaginal delivery, we find that CBE attendance was not associated with likelihood of vaginal delivery among either primiparous or multiparous women. However, both primiparous and multiparous women who attended CBE classes were significantly more likely to say they would request a future, elective cesarean. Furthermore, these effects were in the opposite direction of effects for natural birth attitudes. Our findings suggest that contemporary CBE classes may be a form of “anticipatory socialization”, potentially priming women’s acceptance of medicalized childbirth.

The purpose of this paper is to develop a better understanding of the state of knowledge of students and faculty on the Michigan State University (MSU) campus; identify relevant gaps in knowledge and misconceptions about recycling; and provide recommendations regarding how these gaps and misconceptions may be addressed through education and outreach.

Using mental models analysis, the current state of knowledge possessed by students and faculty was compared with a comprehensive inventory of on‐campus recycling procedures and opportunities.

By combining data from individual mental models elicited from students and faculty members, an overall mental model that depicted the frequency with which subjects understood MSU‐specific recycling concepts was developed. This composite model, and the accompanying statistical analysis, revealed important gaps – on part of both students and faculty – in understanding for several key recycling concepts that are relevant to established campus‐based waste reduction practices.

The mental models approach, which to the authors' knowledge has yet to be applied to campus sustainability initiatives, provides program managers and outreach specialists with a constructive and transparent opportunity to develop and deploy program information that builds on existing knowledge while also meeting the new information needs of key stakeholders.

Investigates the differences in protocols between arbitral tribunals and courts, with particular emphasis on US, Greek and English law. Gives examples of each country and its way of using the law in specific circumstances, and shows the variations therein. Sums up that arbitration is much the better way to gok as it avoids delays and expenses, plus the vexation/frustration of normal litigation. Concludes that the US and Greek constitutions and common law tradition in England appear to allow involved parties to choose their own judge, who can thus be an arbitrator. Discusses e‐commerce and speculates on this for the future.

The complex value chain that facilitates local food production and consumption includes purveyors positioned across a range of marketspaces who through the various ways they present and sell their products help create and convey the meaning of “local food.” Limited governance within local food systems (LFSs) and a lack of consensus on the definition of “local food” provide purveyors with notable latitude in how they frame the meaning of “local” in the food products they produce, market, and sell. Consequently, the expansion of food products that are framed as being “local” within conventional marketspaces threatens to convolute the meaning and representation of local food within specific LFSs and across the broader local food movement (LFM). Here, I use a structured photo analysis design to explore the elements that influence the visual representation of “local food” by purveyors within five farmers’ markets and five grocery stores located across the Southern Arizona LFS (SALFS). I consider the farmers’ markets to be alternative marketspaces and the grocery stores to be conventional marketspaces. The data consist of 683 original photos taken of local food framing practices within the farmers’ markets and grocery stores and extensive field notes captured throughout multiple direct observations at each market space. My exploration is guided by a theoretical framework composed of constructs specific to institutional logic, product framing, and taste regimes. The findings illustrate how local food framing practices across alternative and mainstream marketspaces foster a local food taste regime that fails to convey the fundamental principles and values of the LFM. Recommendations for both practice and research are developed from the findings.

This paper aims to contribute to the ethical debate over roles and responsibilities to address the injustices of climate change and its impacts. The current impasse over taking action may lie in the very different ways people view the world and their place in it. The aim is to explore some profound contradictions within differing strands of knowledge feeding into common understandings of climate justice.

A literature review of appropriate peer-reviewed and “grey” literature was conducted with a view to defining the term “climate justice”.

In addition to there being no single, clear definition of climate justice, a fundamental schism was found between what indigenous peoples want to see happen and what industrialised nations can do with respect to both the mitigation of, and adaptation to, climate change.

One limitation to defining climate justice, and reason for publishing, is the lack of peer-reviewed work on this topic.

This paper has many practical implications, the most fundamental of which is the need to reach a consensus over rights to the Earth’s resources. If humanity, within which there are many societies, chooses to follow a truly equitable path post 2015, industrialised countries and corporations will need to move away from “endless growth economics”. The ways in which climate justice might be operationalised in future are considered, including the concept of a “climate-justice” checklist.

While the reconciliation proposed in this paper might be considered idealistic, unless it is acknowledged the Earth’s resources are limited, over-exploited and for all people to use sustainably, thus requiring a reduction in consumption by individuals relatively affluent in global terms, climate negotiators will continue talking about the same issues without achieving meaningful change.
