The purpose of this paper is to develop a hybrid additive/subtractive manufacturing platform for the production of high density ceramic components.

Fabrication of near-net shape components is achieved using 96 per cent Al3O2 ceramic paste extrusion and a planarizing machining operations. Sacrificial polymer support can be used to aid the creation of overhanging or internal features. Post-processing using a variety of machining operations improves tolerances and fidelity between the component and CAD model while reducing defects.

This resultant three-dimensional monolithic ceramic components demonstrated post sintering tolerances of ±100 µm, surface roughness’s of ∼1 µm Ra, densities in excess of 99.7 per cent and three-point bending strength of 221 MPa.

This method represents a novel approach for the digital fabrication of ceramic components, which provides improved manufacturing tolerances, part quality and capability over existing additive manufacturing approaches.

Investigates ‘end paper advertising’ (publishers inclusion in own publications of additional printed matter not connected with the primary text). Makes note of books and other publications from as far back as 1751 ‐ ‘The Gardeners Kalendar’ and goes on to give an in‐depth study of this area. Concludes that this study covers a heretofore‐uncovered area of interest.

This study aims to investigate the growing use of financial metrics (such as return on investment [ROI]) to measure performance and evaluate human capital (HC) investments.

The research employed an embedded case study approach, examining how one ROI approach was applied to evaluating HC investments, across three sectors (corporate, public health and international development).

Three major findings emerged in this study: First, interpretations of ROI can lead to ambiguity during implementation. ROI is interpreted trichotomously – metaphorically, as a desire for value; literally, as a metric; and procedurally, as a method for planning and evaluating HC investments. Second, understanding, measuring and tracking the domains of people performance (cognitive, affective and psychomotor) is vital to evaluating the impact of HC investments because this is where the change in behavior occurs. Third, although the logic model measures the change in process following an intervention (input-activity-output-outcome-impact), other approaches measure the change in behavior of people in the intervention (people performance).

These findings provide clarity for practitioners about challenges when applying ROI.

This is the first study to explore how the ROI financial metric is applied in a new domain by first examining its interpretation. It elucidates the use of ROI in practice, as well as the different purposes of key ROI approaches.

The purpose of this paper is to survey water-governance issues impacting women in Mexico and steps that have been taken to rectify the issues, including factors that impact the success of such ventures.

Various major academic databases were searched for material pertaining to the issue of water management and gender in Mexico, such as EBSCOHost and JSTOR. Both global and regional concerns were a factor in this search. Material was considered on the basis of its recency, academic import, and specificity.

The review finds that though gender has become a primary concern in addressing water management and other environmental issues, debate has occurred as to whether a perspective of gender mainstreaming or gender-specific projects is preferable in addressing this issue. Although success in implementing gender mainstreaming has been attained by several major organizations, there does not yet exist conclusive evidence that this approach yields desired results.

Information about the efficacy of water access programs is not always available and it is frequently inaccurate. Therefore, much information used in this review takes the form of observations about water policy and its efficacy in regard to gendered approaches.

Women and girls are unevenly affected by a lack of access to water, as it is typically women who bear the brunt of managing household water, and they are more significantly impacted by lacking hygiene facilities.

The purpose of this paper is to explore the correlation among health outcomes, and civil and political rights (CPR) and also economic, social and cultural rights.

The study uses cross-sectional data from 161 countries. The authors use health outcomes and human rights variables in the model. In order to combine dimensions of human rights, this paper uses factor analysis and obtains proxy variables that measure economic, social and cultural rights and CPR. The two proxy variables are used as independent variables to explain variations in health in a regression model. The paper then classifies countries by cluster analysis and explores the patterns of different components of human rights and health outcomes across country clusters.

The regression model demonstrates that the economic, social and cultural rights variables explain variations in all health outcomes. The relationship between CPR and health is weaker than that of the economic, social and cultural rights. Cluster analysis further reveals that despite the country’s commitment to CPR, those that highly respect economic, social and cultural rights lead to superior health outcomes. The more respect a country has for economic, social and cultural rights, the better the health outcomes for the citizens of that country.

National policies should consider equal emphasis on all dimensions of human rights for further improvements in health.

The sole promotion of CPR such as democracy and empowerment, absence of adequate support of economic, social and cultural rights such as rights to housing, education, food and work can only contribute partially to health.

This chapter considers the mobilities of families subject to child protection involvement at the threshold of the birth of a new baby. The author presents data arising from an ethnographic study of child protection social work with unborn babies. This study aimed to draw near to social work practice within the Scottish context through mobile research methods and included non-participant observations of a range of child protection meetings with expectant families. Research interviews were sought with expectant mothers and fathers, social workers and the chair persons of Pre-birth Child Protection Case Conferences. Case conferences are formal administrative meetings designed to consider the risks to children, including unborn children. This chapter focusses on the experiences of expectant parents of navigating the child protection involvement with their as yet unborn infant. The strategies that parents adopted to steer a course through the multiple possibilities in relation to the future care of their infant are explored here. Three major strategies: resistance, defeatism and holding on are considered. These emerged as means by which expectant parents responded to social work involvement and which enabled their continued forwards motion towards an uncertain future.

The vast bulk of the discourse surrounding reproduction is centered on women. Yet, the rate of childlessness in the United Kingdom (and much of the world) is higher among men. Recently, there has been an increased focus on fatherhood and fathering in academia, policy, practice, and the general media. However, data on men who do not become fathers has been excluded and their experiences minimized and dismissed. Infertility research has shown that failure to achieve the high social status of parenthood has the similar effects on mental and physical health as a diagnosis of life-threatening illness. In this chapter, I will draw on two qualitative research studies to show how not achieving the pronatalist ideal of parenthood impacts on men’s identity, sense of self, behaviors, health and well-being and social networks across the life course. The workplace is an arena where people who do not fit socio-cultural norms and expectations are overtly and/or covertly stigmatized and discriminated against through policy, working practices and everyday interaction between groups and individuals. I will argue that failing to acknowledge men’s experience of non-reproduction has a significant impact on both individuals and institutions alike.

Purpose: To present small cases of teachers who undertook inquiry-based collaborative work to implement and refine disciplinary literacy instruction in various content areas.

Design: Disciplinary literacy is explored alongside best practices in teacher professional learning, since disciplinary literacy is an instructional shift. This chapter addresses the question of how teachers might use an exemplary collaboration process to identify and test promising disciplinary literacy instructional practices.

Findings: Findings from various research projects point toward inquiry and collaboration as promising mechanisms for refining instruction to make it more disciplinary in purpose and implementation.

Practical Implications: The authors argue that disciplinary literacy is a relatively new conception of literacy skills in various content areas, and therefore jumping immediately to exemplary practices is unwise. Instead the authors recommend collaboration and inquiry as tools to generate and refine practices thoughtfully over time.
