Machine learning and design of experiments with an application to product innovation in the chemical industry

Industrial statistics plays a major role in the areas of both quality management and innovation. However, existing methodologies must be integrated with the latest tools from the field of Artificial Intelligence. To this end, a background on the joint application of Design of Experiments (DOE) and Machine Learning (ML) methodologies in industrial settings is presented here, along with a case study from the chemical industry. A DOE study is used to collect data, and two ML models are applied to predict responses which performance show an advantage over the traditional modeling approach. Emphasis is placed on causal investigation and quantification of prediction uncertainty, as these are crucial for an assessment of the goodness and robustness of the models developed. Within the scope of the case study, the models learned can be implemented in a semi-automatic system that can assist practitioners who are inexperienced in data analysis in the process of new product development.     

Children's participation in post-divorce decision-making: The role of conflict and attachment

Increased child participation in decision-making about custody and visitation when parents separate is an explicit political goal. This study delineates central family processes associated with child participation in post-divorce decision-making, both in mediation and in the home. Children recruited to the Dynamics of Family Conflict Study at Norwegian family counselling centres (7–15 years, n = 554) completed surveys about interparental conflict, attachment security and whether they had been invited to participate in mediation and share their views at home. Results showed a strong correlation between the two decision-making arenas as children who were invited to participate in mediation were also more likely to have been asked about their views at home, and vice versa. Mixed-effects logistic regression analyses indicated that attachment security to mothers predicted that children were invited to participate in mediation. Older children were more likely to have been invited to participate both at home and in mediation. More child-related interparental conflicts predicted that children did not know if they had been consulted at home. The study points to the need for developing better practices for including younger children.     

Welfare municipalities: economic resources or party politics? Norwegian local government social programs of the 1920s

This article analyses the introduction of Norwegian local government social security programs for the elderly, disabled persons, widows and single mothers in the 1920s. The role of local government as an agent and initiator of welfare state development has been for the most part neglected within the welfare state literature. Indeed, the first social security programs in Norway were introduced by local governments, affecting nearly half of the population. Even if these programs were not very generous compared with the social security programs of our time, many of them were equal to, or even more generous than, the national pension scheme introduced in 1936. This article examines what distinguished the social security municipalities from those that did not implement such programs, and the variation in generosity profiles. The conclusion is that the main determinant regarding the implementation and generosity of the local social security programs is the political strength of the two Norwegian socialist parties at the time – the Social democratic party and the Labour party – both being too impatient to wait for a national social security plan, and both being willing to mobilise economic resources through taxation and borrowing.     

Networking Enforced – Comparing Social Services' Collaborative Rationales across Different Welfare Regimes

Collaboration and networking are ubiquitous, versatile features of social service provision in most Western countries. However, it is an open question whether networking means and entails the same across countries. Comparing regulatory frameworks in three jurisdictions representing distinctive ‘worlds of welfare services’ – Germany, Norway and Quebec – this article aims at eliciting the normative rationales that underpin and inform local service networks in child welfare and protection (CWP) systems. In Norway, where services are little diversified and largely insular, networking appears as a way of opening up for greater organizational plurality, within and beyond the public sector realm. In Germany in contrast, where services are highly pluralized and fragmented, networks are seen as an instrument for streamlining complexity. As for Quebec – an intermediate case in some respects – networking is envisioned as a catalyst for aligning two co‐existing service streams and mitigating the child protection–family support divide. Interestingly, in all three places, networking is now being enforced through similar highly formalized, top‐down regulatory provisions, even though the intended directions of change differ markedly. This has implications for CWP policy as well as research on networks at large.
