Implementation guidelines for mass customization: current characteristics and suggestions for improvement

Interest in mass customization (MC) is increasing in both industry and academia. Academic research on MC implementation guidelines (IGs) has, however, lagged behind other research streams in the MC literature. The present article reviews the existing literature on MC-IGs and inductively derives a classification scheme for prior research findings to identify potential areas for further research. While the issue of what enables MC has been intensively researched, investigation of several questions is still required, such as which enablers should be implemented and in what sequence, depending on the specific context in which MC is pursued. Other areas for future study of MC-IGs include applicability context specifications, as-is analysis tools, hindrance factors and required resources. This article complements previous MC literature reviews by providing an overview of MC-IGs available in the literature, identifying the building blocks of MC-IGs and proposing a definition of MC-IGs that can be used as a basis for future research in MC implementation.     

Are Major Events Capable of Affecting Country Rankings? Validating Composite Indexes of Human Progress and Environmental Performance

A desired characteristic of composite indicators is sensitivity to major adverse events. This paper explores how major civil wars and the 2004 tsunami have influenced Human Development Index (HDI) and Environmental Performance Index (EPI) index values of the affected countries, respectively. The analysis shows that HDI and EPI scores have barely changed, being almost exclusively due to variations in GNI/capita for HDI and air quality for EPI. This casts doubt on the composite indexes’ usefulness and their ability to reflect major environmental and societal changes in the affected countries, or shows which dimensions are truly resilient to these events and can constitute a sustainable base for postwar/post-disaster recovery. Human progress and ecological indicators may need an overhaul, in order to account for the changes that actually happen at a point in time, in order to capture substantial changes in the socio-economic and ecological fabric of a country.     

‘Kids’ Skills’ and ‘Mission Possible’ Innovations: Solution-Focused Brief Therapy Models for Working with Children and Adolescents Revised and Expanded

This article explores the ‘Kids’ Skills’ and ‘Mission Possible’ models of solution-focused brief therapy (SFBT) with children and adolescents. Both models are presented, compared, revised, and expanded with further ideas and therapeutic tools in three crucial areas: 1. Future direction, 2. Resources, and 3. Initiation of change (action). Future direction is expanded by preferred future, skill(s), and goal(s). Resources is expanded by ‘small talk,’ progress and confidence scales, exceptions, metaphors, and engagement of supporters. Initiation of change (action) goes beyond practicing the skill to experiments or steps towards the goal. This gives more flexibility to therapists using SFBT with their clients. All this is illustrated with case examples.     

Inference for cluster point processes with over- or under-dispersed cluster sizes

Cluster point processes comprise a class of models that have been used for a wide range of applications. While several models have been studied for the probability density function of the offspring displacements and the parent point process, there are few examples of non-Poisson distributed cluster sizes. In this paper, we introduce a generalization of the Thomas process, which allows for the cluster sizes to have a variance that is greater or less than the expected value. We refer to this as the cluster sizes being over- and under-dispersed, respectively. To fit the model, we introduce minimum contrast methods and a Bayesian MCMC algorithm. These are evaluated in a simulation study. It is found that using the Bayesian MCMC method, we are in most cases able to detect over- and under-dispersion in the cluster sizes. We use the MCMC method to fit the model to nerve fiber data, and contrast the results to those of a fitted Thomas process.

     

Challenging Parenting Behavior from Infancy to Toddlerhood: Etiology,Measurement, and Differences between Fathers and Mothers

Based on evidence that fathers show more challenging and physical play than mothers, it has been theorized that fathers have a different parenting role, more focused at stimulating exploration and taking chances. Challenging parenting behavior (CPB) may foster confidence and buffer against anxiety development in children. In this study, CPB was assessed in fathers and mothers at child ages of 4 months, 1 year, and 2.5 years, using newly developed questionnaires and observational tasks. Reliability of the questionnaire and observational measures was good, and fathers' and mothers' self‐rated CPB showed a similar factor structure. Modest and significant convergence between questionnaires and observations provided support for validity of CPB, whereas negative correlations with overprotection supported divergent validity. CPB correlated positively with warmth. We further found moderate to high stability of CPB from early infancy to toddlerhood, and interparental correspondence in CPB. Fathers and mothers did not differ in observed CPB, but fathers rated themselves higher than mothers in toddlerhood. It is concluded that the development of the instruments to assess CPB was successful. Overall, the results reveal similarities rather than differences between fathers' and mothers' CPB in early childhood. The potential relevance of CPB in child development and psychopathology is discussed.
