Experiments are the backbone of the development process of data-driven predictive models for scientific applications. The quality of the experiments directly impacts the model performance. Uncertainty inherently affects experiment measurements and is often missing in the available data sets due to its estimation cost. For similar reasons, experiments are very few compared to other data sources. Discarding experiments based on the missing uncertainty values would preclude the development of predictive models. Data profiling techniques are fundamental to assess data quality, but some data quality dimensions are challenging to evaluate without knowing the uncertainty. In this context, this paper aims to predict the missing uncertainty of the experiments.

This work presents a methodology to forecast the experiments’ missing uncertainty, given a data set and its ontological description. The approach is based on knowledge graph embeddings and leverages the task of link prediction over a knowledge graph representation of the experiments database. The validity of the methodology is first tested in multiple conditions using synthetic data and then applied to a large data set of experiments in the chemical kinetic domain as a case study.

The analysis results of different test case scenarios suggest that knowledge graph embedding can be used to predict the missing uncertainty of the experiments when there is a hidden relationship between the experiment metadata and the uncertainty values. The link prediction task is also resilient to random noise in the relationship. The knowledge graph embedding outperforms the baseline results if the uncertainty depends upon multiple metadata.

The employment of knowledge graph embedding to predict the missing experimental uncertainty is a novel alternative to the current and more costly techniques in the literature. Such contribution permits a better data quality profiling of scientific repositories and improves the development process of data-driven models based on scientific experiments.

The purpose of this study is to extend the research on fashion renting (FR) by investigating how personal and social motives (i.e. “subjective norms”, “perceived behavioural control”, “sustainable orientation” and “FR benefits”) affect consumers’ attitudes and intentions towards it. In addition, personality traits are investigated as potential antecedents of FR, resulting in the proposal of an overall framework that combines the theory of planned behaviour with the trait theory approach.

Data were collected in Italy from a sample of 694 consumers, mainly females (88%), with an average age of 28.8 years and coming from all over the country. The collected data were then processed via structural equation modelling.

The results indicated that intention towards FR is influenced by attitude, which, in turn, is affected by social norms, perceived behavioural control, sustainable orientation and FR benefits. Furthermore, only fashion leadership acts as a direct antecedent of FR attitude, while the need for uniqueness and materialism plays critical roles as predictors of personal and social motives. Subjective norms and perceived behavioural control also serve as mediators of the significant relationships between personality traits and attitudes towards FR.

The study provides useful implications for fashion rental companies in attracting consumers and offers a foundation for further research on transforming traditional consumption into a more sustainable one.

The study presents new knowledge on the rental phenomenon in the fashion sector by responding to the call to deepen the analysis of factors that influence consumers’ adoption of FR from the perspectives of personal and social motives and personality traits.

Can we broaden the boundaries of the history of economic thought to include positionalities articulated by grassroots movements? Following Keynes’s famous remark from General Theory that ‘practical men […] are usually the slaves of some defunct economist,’ we might be wont to dismiss such a push from below. While it is sometimes true that grassroots movements channel preexisting economic thought, I wish to argue that grassroots economic thought can also precede developments subsequently elaborated by economists. This paper considers such a case: by women at the intersection of the women’s liberation movement and the claimants’ unions movement in 1970s Britain. Oral historical and archival work on these working-class women and on achievements such as their succeeding to establish unconditional basic income as an official demand of the British Women’s Liberation Movement forms the springboard for my reconstruction of the grassroots feminist economic thought underpinning the women’s basic income demand. I hope to demonstrate, firstly, how this was a prefiguration of ideas later developed by feminist economists and philosophers; secondly, how unique it was for its time and a consequence of the intersectionality of class, gender, race, and dis/ability. Thirdly, I should like to suggest that bringing into the fold this particular grassroots feminist economic thought on basic income would widen the mainstream understanding and historiography of the idea of basic income. Lastly, I hope to make the point that, within the history of economic thought, grassroots economic thought ought to be heeded far more than it currently is.

The role of caregivers and issues of parenting are controversial in research on disability. While appreciating the historical and political reasons to critique power relations in care systems and care relations, we argue that it is important to consider parents' and other caregivers' positions. A reconsideration provides insights into pervasive effects of ableism defining not only the individual child but parents and other relatives as well. We draw from extensive research on couples parenting a child with disability in Germany (Tröndle, 2022a). This study seeks to understand how parents of a child with disability cannot avoid understanding themselves as “special parents.” Through analyzing shared life stories of couples and individual biographies, the study reconstructs how identities evolve differently depending on their work-sharing arrangements. Based on our findings, the couples experience difficulties in maintaining dual employment arrangements. They become “unable” to step outside of the logic of welfare and health provision and structures of the labor market. Couples begin to explain their situation and the discrimination they experience by reflecting themselves as “special parents.” Heteronormative and ableist expectations hinder them in articulating resistance and gaining agency as allies of their children, facilitating positions of complicity. We argue that the approach suggested by this study – namely including the ambiguous situation of caregivers in Disability Studies – can encourage other researchers to consider othering and ableism of and by caregivers.

It has been 50 years since the publication of Studs Terkel’s groundbreaking book, Working, which consists of a compilation of interviews carried out with over 130 workers in the United States. In this chapter, the author revisits this masterpiece, which offers a penetrating analysis of the dehumanization and degradation of work. The author argues that Working is an ode to, and guide for, ethnographic scholarship on work and that it remains as powerful and relevant today as when it was originally published a half of a century ago.

Goffman’s (1961) work on total institutions has been relatively neglected in the fields of organizational research. This paper compares the conceptions of obedience to authority in two different types of voluntary total institutions and how such conceptions affect interaction contrary to the aims of the organizations. Consequently, by addressing how conceptions of authority and constructions of the obedient self shape conditions for underlife, the analysis provides knowledge about the variety of ways in which total institutional authority works and contributes to the understanding of the mechanisms of organizational underlife.
