This article presents a locally conservative projection method which aims to preserve the integral of a function and one operator among grad, div, or curl.

After a theoretical description of the projection methods, the locally conservative projection is analytically tested and compared with the orthogonal method. In the second part, the implementation of the methods is described, and improvements are proposed. An industrial application of the present work, consisting in a magneto-thermal coupled problem, is then presented.

The implementation of the conservative method is simpler than the implementation of the orthogonal method while presenting similar behaviour in terms of accuracy and conservation.

The locally conservative method is extended to curl-conform and div-conform elements. Furthermore, three-dimensional studies are proposed.

Due to the unique nature of the Cultural and Creative Industries (CCIs), the impact of crowdfunding on them is more significant than on other industries. This study investigates the association between crowdfunding campaigns in four different categories of cultural production and each campaign promoter's decision regarding platform choice.

We classified cultural productions according to the Cultural Enterprise Framework. We collected data from 1,465 successful, reward-based, culture crowdfunding campaigns from five Nordic countries (Denmark, Finland, Iceland, Norway and Sweden). We used binary logistic regression for estimation purposes.

We find that cultural productions with a high degree of cultural affinity are more likely to use a local platform, while cultural productions with a higher degree of complexity in production or with composite motives are more likely to use an international platform. Additionally, the funding goal and the platform's financing model affect the probability of using an international platform.

Our finding is that there is a relationship between cultural production type and crowdfunding platform choice, and that these choices can be crucial for campaign promoters. Based on the findings and empirical setting, there is evidence that campaign promoters of cultural productions with a cultural affinity orientation may choose to use local platforms, while promoters of projects with complex production requirements or composite motives for using crowdfunding similarly may tend to opt for international platforms. We also propose a framework for the categorisation of cultural productions.

Students have a finite amount of time that they can allocate between commitments of study–work–life. Striking a balance between these competing activities is an individual conundrum and this study aims to explore the impact of extramural activities and paid employment on the academic performance of accounting students.

Guided by Carroll’s model of school learning, the authors adopt a quantitative approach where they survey (N = 264) and gather responses (n = 195) from students with respect to their choices regarding spare time outside study. These perceptions are then compared to their academic performance. Quantitative responses were subsequently triangulated with interview findings to provide in-depth analysis.

Findings provide greater understanding for educators of the student lived experience, which reveals that the work, study and life balance is individually nuanced and is largely driven by the individual’s perceived level of interference from work, which is a significant predictor of academic performance.

Analysis of the determinants of student learning includes prior academic achievement, confidence with numbers, critical thinking, gender and prior accounting knowledge. Yet, little is known about the implication of activities outside the formal curriculum. This study addresses this void in the literature and provides a much-needed link back to accounting faculty’s pedagogical approaches as they adapt to a cohort’s learning behaviour. This study also adds to the debate on the need for more discussion with faculty to allow alternate arrangements based on extramural activities and employment commitments. Greater understanding of study–work–life balance for students provides an opportunity for new dialog between faculty and students.

Coproduction, as one component of cocreation of value, offers many benefits to customers and management, but also requires customers to invest a considerable amount of effort and time. The purpose of this paper is to investigate the coproduction paradox of benefits and costs.

One experimental study and two cross-sectional field studies across three service industries test the nonlinear relationship between level of coproduction and customer loyalty.

Results show not only the optimum level but also the negative effects of increasing levels of coproduction on customer loyalty and, in turn, monetary expenditures. The negative effect can be partially offset by perceived process enjoyment (PE), such that consumers who enjoy the process exhibit increased loyalty after the optimum coproduction point. Customer self-efficacy (SE), however, further strengthens the inverted u-shaped relationship.

Further research should try to replicate the findings in more complex and less hedonic service settings (e.g. financial investments) because both PE and SE might be even more powerful here.

Service managers need to determine the optimal degree to which customers want to engage in the creation of services and avoid overburdening them. Management should further explore opportunities to elicit feelings of fun and enjoyment through coproduction.

Research usually highlights the potential benefits of coproduction for customers and companies and suggests a positive linear relationship between coproduction and success outcomes. This article instead shows that after an optimum level, the marginal benefits of coproduction for customer loyalty turn negative.

The following list is a first attempt to catalogue and describe systematically the British Museum's extensive holdings of early opera librettos and related plays. The great importance of these unpretentious booklets as supplementary and, more often than not, even primary sources for the history and bibliography of dramatic music, besides or instead of the scores, was already clearly recognized in the eighteenth century by Dr. Burney and other scholars. But it is only since 1914, the year in which O. G. T. Sonneck's Library of Congress Catalogue of opera librettos printed before 1800 appeared, that their documentary value could to any greater extent be put to general use in international musicological research. A similar bibliography of the British Museum librettos, while naturally duplicating many Washington entries, would produce a great number of additional tides, not a few of them otherwise unrecorded; it would provide the musical scholar with the key to a collection unequalled elsewhere in Europe, which owing to the peculiar nature of the material is not easily accessible by means of the General Catalogue.

The purpose of this paper is to examine the effect of manufacturers’ co-production strategy on market segmentation and channel performance under retail competition.

It differs from previous empirical studies by primarily focusing on the increment in consumer value accompanying co-production. The authors establish a game-theoretical model to analyze the impact of co-production on market segmentation and the profitability of channel members in a competitive retail environment.

The results reveal that manufacturers introducing co-production expand market coverage and benefit all channel members, when the intensity of competition is sufficiently high, especially for retailers with low-quality levels, who are out of the market without co-production. Furthermore, with the increase in customer valuation through co-production, employing a co-production strategy is always a dominant strategy for manufacturers.

First, although the authors assume a monopoly manufacturer and two duopoly retailers, adding competition between manufacturers should enrich the model. Multiple products with vertical or horizontal differentiation could also be introduced into the model. Second, the authors use the multiplicative utility function to model the value co-creation effect on consumers; however, different utility functions may yield significantly different results and implications. Third, the authors model a one-shot game in a single product selling period; future studies may employ multi-period games to obtain further insight into co-production strategy. Finally, the model assumes that all consumers are homogenous in the extent of value creation and hassle cost. Future research may find it interesting to consider heterogeneity in these characteristics.

The business world today already sees the power of leadership in a supply chain to have shifted from manufacturers to retail giants such as Walmart, Home Depot and Best Buy. The findings also propose a new route to counteract the emergence and rise of dominant retailers. On the other hand, with the application of new technology in the retail industry such as 3D avatar, AR/VR, Internet of Things, consumers are more likely to participate in various forms of co-production activities, how to execute the co-production strategy has become more and more important for managers.

The conclusion of this study points out the way to achieve a win–win outcome under which both channel members including manufacturer and retailers and consumers can be better off, that is, the channel can reach Pareto improvement, so the social welfare is increased accordingly.

The authors propose an analytical framework to examine the effects of co-production and competition on market segmentation and profitability, and prove that co-production is a powerful marketing tool that can attract consumers and increase profitability, which manufacturers can incorporate into their products even in a competitive environment.

By drawing on various theoretical approaches and a gender perspective, this paper aims to examine business model (BM) experimentation as a step towards BM experimentation capabilities as an outcome and, as such, a key antecedent to firm performance.

In this paper, using a unique data set of 444 European small and medium-sized enterprises (SMEs), the authors draw on various theoretical perspectives to devise a structural equation model that examines BM experimentation as a step towards business model innovation (BMI) as an outcome and, as such, a key antecedent to firm performance. Potential differences are examined between female-owned and non-female-owned businesses with regard to hypothesized relations.

Multi-group analysis results reveal that drivers of BM experimentation and the paths linking BM experimentation to overall firm performance are different for female owners in comparison to male owners.

Theoretical and practical implications are various. For SME entrepreneurs, experimenting with their BMs does lead to improved performance.

Despite the increasing number of papers focussing on the relationship between BM and firm performance, the focus on female entrepreneurship, gender differences and BMI, more specifically the process of BMI as BM experimentation, is relatively rare.

The management of children′s literature is a search for value and suitability. Effective policies in library and educational work are based firmly on knowledge of materials, and on the bibliographical and critical frame within which the materials appear and might best be selected. Boundaries, like those between quality and popular books, and between children′s and adult materials, present important challenges for selection, and implicit in this process are professional acumen and judgement. Yet also there are attitudes and systems of values, which can powerfully influence selection on grounds of morality and good taste. To guard against undue subjectivity, the knowledge frame should acknowledge the relevance of social and experiential context for all reading materials, how readers think as well as how they read, and what explicit and implicit agendas the authors have. The good professional takes all these factors on board.

Artificial Intelligence is a general-purpose technology that is bound to affect every industry. To develop successful corporate and business strategies with AI, leaders have to capture the technological opportunity, understand the economics of AI and lead organizational change.

What to do with AI? How to set up for AI? Where is the value? Initial answers to these three fundamental questions are derived based on an interdisciplinary and integrated literature review.

AI leaders pursue competitive advantage by taking up the technological offer to predict-prescribe-automate, they enact machine learning by entering into a portfolio of experiments within a modular strategic framework, they organize the business to form of man-machine teams following the concept of human-agent collectives and they avoid falling victim to exponential growth bias.

In a business environment where the cognification of everything will lead to exponential growth of both, volume of data and intelligence of machines, it will be paramount for strategic leaders to have a robust AI strategy in place and to develop the competencies required for managing the Artificially Intelligent Firm.

This overview enables strategic leaders to prepare themselves and their organizations for AI. It spearheads making required connections between technology, economics and management of AI.

Wales Applied Risk Research Network (WARRN) is a formulation-based technique for the assessment and management of serious risk (e.g. violence to others, suicide, etc.) for users of mental health services which has been adopted across most Child and Adolescent Mental Health Services (CAMHS) across Wales. The paper aims to discuss this issue.

An online survey was disseminated to National Health Service clinicians in CAMHS to evaluate their perceptions of the use and effectiveness of WARRN. Data from 88 clinicians were analysed with both quantitative and qualitative methods.

Clinicians reported increased clinical skills, increased confidence in their assessment and management of risk and in safety planning, the increased safety of service users and the general public, and a belief that WARRN had saved lives. The qualitative data showed that clinicians thought a common risk evaluation instrument across Wales and different agencies had created a common language and understanding that improved communication.

WARRN appears well accepted in CAMHS services with the view that it is having a very positive effect on service user well-being and safety and could be implemented in other services.

This is the first report of a formulation-based approach to the management of serious problem behaviours in CAMHS services.
