Advances in collaborative evaluation

Collaborative evaluation is an approach that offers, among others, many advantages in terms of access to information, quality of information gathered, opportunities for creative problem-solving, and receptivity to findings. In the last decade, collaborative evaluation has grown in popularity along with similar participatory, empowerment, and utilization-focused evaluation approaches. Increasingly, it has brought together evaluators and stakeholders from different sectors, disciplines, and cultures to exchange knowledge on how collaboration can be used as a strategic tool for fostering and strengthening evaluation practice. O'Sullivan (2004) and Rodríguez-Campos (2005, 2008) brought forward collaborative evaluation conceptual frameworks that distinguished it from other approaches. This article updates those conceptual frameworks and discusses key collaborative evaluation advances in order to further clarify and facilitate engagement in sound practice.     

Predicting the Validity of Expert Judgments in Assessing the Impact of Risk Mitigation Through Failure Prevention and Correction

Operational risk management of autonomous vehicles in extreme environments is heavily dependent on expert judgments and, in particular, judgments of the likelihood that a failure mitigation action, via correction and prevention, will annul the consequences of a specific fault. However, extant research has not examined the reliability of experts in estimating the probability of failure mitigation. For systems operations in extreme environments, the probability of failure mitigation is taken as a proxy of the probability of a fault not reoccurring. Using a priori expert judgments for an autonomous underwater vehicle mission in the Arctic and a posteriori mission field data, we subsequently developed a generalized linear model that enabled us to investigate this relationship. We found that the probability of failure mitigation alone cannot be used as a proxy for the probability of fault not reoccurring. We conclude that it is also essential to include the effort to implement the failure mitigation when estimating the probability of fault not reoccurring. The effort is the time taken by a person (measured in person-months) to execute the task required to implement the fault correction action. We show that once a modicum of operational data is obtained, it is possible to define a generalized linear logistic model to estimate the probability a fault not reoccurring. We discuss how our findings are important to all autonomous vehicle operations and how similar operations can benefit from revising expert judgments of risk mitigation to take account of the effort required to reduce key risks.     

Spicing Up a 150-Year-Old Porcelain Factory: Art,Localism and Transnationalism in Arita's Happy Lucky Kiln

The Kouraku Kiln, a 150-year-old Japanese porcelain factory in the traditional rural pottery town of Arita, has been struggling with the economic decline brought by the burst of the bubble in the mid-1990s, rural migration and changes in lifestyle and tastes. Using ethnographic fieldwork, I look at the independent innovative activities that the Kouraku Kiln factory has put into place to overcome such problems: an artist-in-residence program and a treasure hunt, both coordinated by Brazilian ceramic artist and cultural agitator Sebastião Pimenta. By making use of the local history, identity, and infrastructure to attract visitors from all over the world to the production site, Kouraku Kiln has changed its focus from its products by selling knowledge and experiences. Besides contributing to the revitalization of the local economy, the constant presence of Pimenta and other international artists at the factory has added to the creation of multicultural exchanges in the local community, raising issues about social integration and local citizenship. With this case study, I aim to add to discussions about the revitalization of rural places and the regeneration of Japanese traditional crafts through the acknowledgment of globalization and mobility. By addressing issues related to the impact of transnational flows in rural communities, this article argues for the contributions of migrants in their communities of destination and examines the transforming relationships between art, society, and local development.     

A Fuzzy‐Based Risk Assessment Framework for Autonomous Underwater Vehicle Under‐Ice Missions

The use of autonomous underwater vehicles (AUVs) for various scientific, commercial, and military applications has become more common with maturing technology and improved accessibility. One relatively new development lies in the use of AUVs for under‐ice marine science research in the Antarctic. The extreme environment, ice cover, and inaccessibility as compared to open‐water missions can result in a higher risk of loss. Therefore, having an effective assessment of risks before undertaking any Antarctic under‐ice missions is crucial to ensure an AUV's survival. Existing risk assessment approaches predominantly focused on the use of historical fault log data of an AUV and elicitation of experts’ opinions for probabilistic quantification. However, an AUV program in its early phases lacks historical data and any assessment of risk may be vague and ambiguous. In this article, a fuzzy‐based risk assessment framework is proposed for quantifying the risk of AUV loss under ice. The framework uses the knowledge, prior experience of available subject matter experts, and the widely used semiquantitative risk assessment matrix, albeit in a new form. A well‐developed example based on an upcoming mission by an ISE‐explorer class AUV is presented to demonstrate the application and effectiveness of the proposed framework. The example demonstrates that the proposed fuzzy‐based risk assessment framework is pragmatically useful for future under‐ice AUV deployments. Sensitivity analysis demonstrates the validity of the proposed method.     

The Peru Urban Management Education Programme (PEGUP) — linking capacity building with local realities

The development of initiatives for Local Agenda 21 for the cities of Peru, their documentation for the “best practices” programme of HABITAT II, and the demand for a formalized programme of support, capacity building and technical assistance has stimulated the establishment of the Peru Urban Management Education Programme (PEGUP). The PEGUP represents an innovative approach to capacity building, working through different mechanisms of education and training, technical assistance to municipal development of Local Agenda 21 and the promotion of networking and experience exchange. The experiences to date indicate that the set of support mechanisms is in line with the requirements of local governments which need a variety of support on the long road to develop urban management capacities that allow the solution of their urban and environmental problems. PEGUP offers a variety of services which are part of the development strategy of “Forum of Cities for Life” network.     

A Weighted Multidimensional Index of Child Well-Being Which Incorporates Children’s Individual Perceptions

It has been a decade since a landmark piece of work on child well-being measurement based on a summary index was developed in the United States, the Index of Child and Youth Well-Being. Several research studies, both in the U.S. and Europe, followed on from this work. Despite these studies’ valuable contribution, scope exists for further improvements at the methodological level. In the present paper we draw the methodological basis for a new, micro-based summary child well-being index in which children’s views on their own well-being assume a central role and distinct weights (based on the children’s perceptions) to each component that is included in the index are used. Based on 914 pairs of responses of Portuguese children and their carers, the newly proposed index was tested vis-à-vis other methodologies. The econometric estimations show that the significance of all potential well-being determinants (e.g., age, school cycle, mother’s and father’s level of education) remains the same across the distinct methods of calculation of child well-being indexes. However, the consideration of subjective components (degrees of importance and weights) allowed to evidence that the most relevant determinants of child well-being are the set of variables related to the child’s parents, namely education and professional status. In particular, when compared to their counterparts, children whose fathers have higher education degrees reveal an increased overall well-being by around 25 %, whereas children whose fathers are unemployed present a decreased well-being by around 11 %.     

Complex Families and Late‐Life Outcomes Among Elderly Persons: Disability,Institutionalization, and Longevity

The authors examined the effects of marital status and family structure on disability, institutionalization, and longevity for a nationally representative sample of elderly persons using Gompertz duration models applied to longitudinal data from 3 cohorts of the Health and Retirement Study (N = 11,481). They found that parents with only stepchildren have worse outcomes than parents with only biological children. Elderly mothers with only stepchildren become disabled and institutionalized sooner, and elderly men with only stepchildren have shorter longevity relative to their counterparts with only biological children. The effect of membership in a blended family differs by gender. Relative to those with only biological children, women in blended families have greater longevity and become disabled later, whereas men in blended families have reduced longevity. The findings indicate that changing marital patterns and increased complexity in family life have adverse effects on late‐life health outcomes.     

Parenting Mediates the Effects of Income and Cumulative Risk on the Development of Effortful Control

This study tested the hypothesis that the effects of income and cumulative risk on the development of effortful control during preschool would be mediated by parenting. The study utilized a community sample of 306 children (36–40 months) representing the full range of family income, with 29 percent at or near poverty and 28 percent lower income. Two dimensions of effortful control (executive control and delay ability) were assessed at four time points, each separated by nine months, and growth trajectories were examined. Maternal warmth, negativity, limit setting, scaffolding, and responsiveness were observed. Above the effects of child cognitive ability, income, and cumulative risk, scaffolding predicted higher initial levels of executive control that remained higher across the study, and limit setting predicted greater gains in executive control. Parenting did not predict changes in delay ability. Significant indirect effects indicated that scaffolding mediated the effects of income and cumulative risk on growth in executive control. The findings suggest that parenting behaviors can promote effortful control in young children and could be targets of prevention programs in low‐income families.

Long-term care of the disabled elderly: do children increase caregiving by spouses?

Do adult children affect the care elderly parents provide each other? We develop two models in which the anticipated behavior of adult children provides incentives for nondisabled elderly parents to increase care for their disabled spouses. The “demonstration effect” postulates that adult children learn from a parent’s example that family caregiving is appropriate behavior. The “punishment effect” postulates that adult children may punish parents who fail to provide spousal care by not providing future care for the nondisabled spouse if and when necessary. Thus, joint children act as a commitment mechanism, increasing the probability that elderly parents will provide care for their disabled spouses. We argue that stepchildren provide weaker incentives for spousal care because the attachment of a stepchild to a stepparent is likely to be weaker than the attachment of children to parents in a traditional nuclear family. Using data from the HRS, we find evidence consistent with the hypothesis that joint children provide stronger incentives than stepchildren for nondisabled elderly parents to provide care for their disabled spouse.
