An Incremental Learning Method to Support the Annotation of Workflows with Data-to-Data Relations
Workflow formalisations are often focused on the representation of a process with the primary objective to support execution. However, there are scenarios where what needs to be represented is the effect of the process on the data artefacts involved, for example when reasoning over the corresponding data policies. This can be achieved by annotating the workflow with the semantic relations that occur between these data artefacts. However, manually producing such annotations is difficult and time consuming. In this paper we introduce a method based on recommendations to support users in this task. Our approach is centred on an incremental rule association mining technique that allows to compensate the cold start problem due to the lack of a training set of annotated workflows. We discuss the implementation of a tool relying on this approach and how its application on an existing repository of workflows effectively enable the generation of such annotations
Open innovation and firm performance in small-sized R&D active companies in the chemical industry:the case of Belgium
This paper relates the practice of open innovation in small R&D active chemical companies to firm performance in terms of employment and financial position. This relationship is examined during a period of economic downturn and applied to the Belgian situation. The Belgian case is interesting since it is characterised by a high economic importance of the chemical industry and a strongly developed national (eco-) innovation system in the sector. According to their different evolution over the last decade, a distinction is made between basic chemicals and pharmaceuticals. In terms of open innovation strategy, a distinction is made between companies innovating completely internally (closed innovators), firms engaged in R&D outsourcing, firms engaged in research cooperation, and firms integrating outsourcing and cooperation in their knowledge sourcing strategy. After controlling for a broad range of R&D characteristics, we found that firms engaged in outsourcing or having an integrated open innovation approach performed better in terms of the evolution of employment during the period 2005-2010. Also, the analysis revealed firms having a formal R&D manager and a long-term research vision more often combine average to strong employment growth with a prosperous financial position.<br
Een webbased Community of Learners (CoL) voor beroepsvaardigheden
Studenten in de lerarenopleidingen van de Universiteit Twente kregen een website aangeboden als platform voor informatie-uitwisseling betreffend vakoverstijgende beroepsvaardigheden van leraren. Inzet was de ontwikkeling van een Community of Learners. Het Ruud de Moor centrum leverde de expertise en de techniek.\ud
De onderzoeksvraag luidde: âIs een vakoverstijgende (virtuele) Community of Learners een gewenste aanvulling op het instrumentarium in de lerarenopleidingen van ELAN?â We vroegen de studenten naar de waardering voor en meerwaarde van een dergelijke CoL. Onder de gegeven omstandigheden is de meerwaarde niet ervaren maar de DIOâs zien wel mogelijkheden

A cross-national study on the antecedents of workâlife balance from the fit and balance perspective
Drawing on the perceived workâfamily fit and balance perspective, this study investigates demands and resources as antecedents of workâlife balance (WLB) across four countries (New Zealand, France, Italy and Spain), so as to provide empirical cross-national evidence. Using structural equation modelling analysis on a sample of 870 full time employees, we found that work demands, hours worked and family demands were negatively related to WLB, while job autonomy and supervisor support were positively related to WLB. We also found evidence that resources (job autonomy and supervisor support) moderated the relationships between demands and workâlife balance, with high resources consistently buffering any detrimental influence of demands on WLB. Furthermore, our study identified additional predictors of WLB that were unique to some national contexts. For example, in France and Italy, overtime hours worked were negatively associated with WLB, while parental status was positively associated with WLB. Overall, the implications for theory and practice are discussed.Peer ReviewedPostprint (author's final draft
10 Years of C-K Theory: A Survey on the Academic and Industrial Impacts of a Design Theory.
The goal of our research1 was to understand what is expected today from a design theory and what types of impact such type of scientific proposition may reach. To answer these questions with a grounded approach we chosed to study the developement of C-K theory as phenomenon per se that can inform our research work. C-K theory is clearly recognized as a design theory and it is a good representative of the level of generality and abstraction of contemporary design theory. Indeed, the validity of the theory as such has already been documented (e.g. Hatchuel & Weil 2002, 2003, 2008, 2009; Kazakçi 2009; Reich et al 2010; Le Masson et al 2010; Ullah et al 2012). Instead the current work sets out to understand the dissemination and the impact of the theory in both academic and industrial fields. The data collection overlooks the literature on C-K theory in English and in French, and includes interviews and feedbacks of students and industrial partners who applied C-K methodologies and tools. This research confirms the rapid diffusion and multiples impact of C-K theory. Beyond, such study signals that there are important expectations and potential impacts of a Design Theory within the field of knowledge at large. However there are strong conditions to meet these expectations: generality, generativity, and relatedness to contemporary sciences. A similar research could be done on Nam Suh's axiomatic approach to further test these conditions. It is impossible to say what will be the next generations of Design theory but it is sure that they should progress on these directions
Blurred lines: work, eldercare and HRM
peer-reviewedThe full text of this article will not be available in ULIR until the embargo expires on the 27/06/2020Increased levels of female labour market participation have impacted on the ability of families to provide care for elderly relatives in many industrialised societies. While workâfamily balance has received significant academic attention, less attention has focused specifically on individuals with eldercare responsibility, a cohort which accounts for a growing segment of the labour market internationally. Taking a qualitative research approach this paper uses work/family border theory to the constraints and facilitators to reconciling care and employment for employees working full-time in Ireland. The findings highlight the significant impact that eldercare provision has on employees with regard to day-to-day work commitments. We find that while general workâlife balance policies exist within organisations, that the design and functionality of such policies are of limited value to elder caregivers. Furthermore, this paper highlights how the lack of formal HR policies around eldercare within organisations results in a reliance on supervisory discretion. We make some recommendations for organisational level strategies to address the needs of a growing number of caregivers.peer-reviewe
Quantitative Concept Analysis
Formal Concept Analysis (FCA) begins from a context, given as a binary
relation between some objects and some attributes, and derives a lattice of
concepts, where each concept is given as a set of objects and a set of
attributes, such that the first set consists of all objects that satisfy all
attributes in the second, and vice versa. Many applications, though, provide
contexts with quantitative information, telling not just whether an object
satisfies an attribute, but also quantifying this satisfaction. Contexts in
this form arise as rating matrices in recommender systems, as occurrence
matrices in text analysis, as pixel intensity matrices in digital image
processing, etc. Such applications have attracted a lot of attention, and
several numeric extensions of FCA have been proposed. We propose the framework
of proximity sets (proxets), which subsume partially ordered sets (posets) as
well as metric spaces. One feature of this approach is that it extracts from
quantified contexts quantified concepts, and thus allows full use of the
available information. Another feature is that the categorical approach allows
analyzing any universal properties that the classical FCA and the new versions
may have, and thus provides structural guidance for aligning and combining the
approaches.Comment: 16 pages, 3 figures, ICFCA 201
