The purpose of this paper is to propose general parallelism techniques for holistic twig join algorithms to process queries against Extensible Markup Language (XML) databases on a multi‐core system.

The parallelism techniques comprised data and task parallelism. As for data parallelism, the paper adopted the stream‐based partitioning for XML to partition XML data as the basis of parallelism on multiple CPU cores. The XML data partitioning was performed in two levels. The first level was to create buckets for creating data independence and balancing loads among CPU cores; each bucket was assigned onto a CPU core. Within each bucket, the second level of XML data partitioning was performed to create finer partitions for providing finer parallelism. Each CPU core performed the holistic twig join algorithm on each finer partition of its own in parallel with other CPU cores. In task parallelism, the holistic twig join algorithm was decomposed into two main tasks, which were pipelined to create parallelism. The first task adopted the data parallelism technique and their outputs were transferred to the second task periodically. Since data transfers incurred overheads, the size of each data transfer needed to be estimated cautiously for achieving optimal performance.

The data and task parallelism techniques contribute to good performance especially for queries having complex structures and/or higher values of query selectivity. The performance of data parallelism can be further improved by task parallelism. Significant performance improvement is attained by queries having higher selectivity because more outputs computed by the second task is performed in parallel with the first task.

The proposed parallelism techniques primarily deals with executing a single long‐running query for intra‐query parallelism, partitioning XML data on‐the‐fly, and allocating partitions on CPU cores statically. During the parallel execution, presumably there are no such dynamic XML data updates.

The effectiveness of the proposed parallel holistic twig joins relies fundamentally on some system parameter values that can be obtained from a benchmark of the system platform.

The paper proposes novel techniques to increase parallelism by combining techniques of data and task parallelism for achieving high performance. To the best of the author's knowledge, this is the first paper of parallelizing the holistic twig join algorithms on a multi‐core system.

The purpose of this paper is to study and assess the content, functioning and impact of institutional reforms aiming to enhance collective and holistic political leadership at the level of local government.

The authors conduct a comparative case study of two Danish frontrunner municipalities drawing on relevant documents and qualitative interviews with both elected politicians and public administrators.

The authors found that institutional design is effective in promoting collective and holistic political leadership at the local level, even if no formal design options are available and the municipalities have to invent their own designs. Support both from both councilors and administrators is paramount for successful implementation of local political leadership reforms.

Due to the purposive selection of a limited number of cases, the findings cannot be generalized to the population from which the cases are drawn. However, other municipalities may learn from and become inspired by the positive impact of the new institutional designs on collective and holistic political leadership.

Whereas some institutional political leadership reforms aim to enhance the power of the mayor and other reforms aim to create a cabinet or a committee system, the reforms the authors are studying aim to create a space for local councilors to work together across party and sector lines in creating collective and holistic policy solutions. The study shows that it is crucial that local councilors are involved in cross-boundary agenda setting before developing policies in standing committees and endorsing them in the council assembly.

There is a large amount of more or less wicked problems that require the formulation and implementation of innovative policy solutions, which, in turn, call for a clear and determined political leadership. However, local politicians typically suffer from decoupling and tunnel vision. The results show that these problems can be solved through new institutional designs that promote a more collective and holistic political leadership that can take the local community forward.

Few studies have hitherto addressed the need for institutional reforms enabling collective and holistic political leadership through both theoretical and empirical analyses, but that is exactly what the authors try to accomplish.

The purpose of this paper is to point out the importance of taking a holistic approach to bit preservation when setting out to find an optimal bit preservation solution for specific digital materials. In the last decade there has been an increasing awareness that bit preservation, which is to keep bits intact and readable, is far more complex than first anticipated, even in this narrow definition. This paper takes a more holistic approach to bit preservation, and looks at how an optimal bit preservation strategy can be found, when requirements like confidentiality, availability and costs are taken into account.

The paper describes the various findings from previous research which have led to the holistic approach to bit preservation. This paper also includes an introduction to digital preservation with a focus on the role of bit preservation, which sets the scene for why bit preservation deserves attention in a holistic approach.

The paper presents different means to find an optimal bit preservation strategy. This consists of a model to delimit bit preservation activities, and will briefly discuss how specific material can require different bit preservation strategies as well as pointing to how such strategies can be evaluated.

The operational results described here are still missing work to be fully operational. However, the holistic approach is in itself an important result. Furthermore, in spite of the shortcomings, the results can assist in analysis and evaluation of bit preservation strategies.

This paper is an extract of the findings presented in the doctoral thesis “A holistic approach to bit preservation”. The findings are relevant for any organisation that is required to do bit preservation of its digital material.

The purpose of this paper is to discuss how a “holistic approach” is enacted in two interventions accommodating the same target group, young adults with offending behaviour and drug use experiences, but offered in very different contexts, the Prison Service and the community. The aim is to show how enactments of a “holistic approach”, although similar on paper, differ in welfare institutional practices due especially to organisational and structural conditions.

The paper is based on qualitative semi-structured interviews and written material from and about the two interventions.

Different enactments of a “holistic approach”, due to organisational and structural conditions of the interventions, construct different possibilities for institutional identities. These insights could be useful to take into consideration when discussing prevention initiatives (in a broad sense) for young people with complex problems, including co-occurring offending behaviour and drug use experience.

Research with a focus on citizens with complex problems who do not comply with OR conform to standard welfare institutions are limited. The authors contribute to this literature by focussing on young adults with offending behaviour and drug experiences.

Beyond a mandated use, rationales behind executive choice to accept or reject building information modelling (BIM) are ambiguous. BIM acceptance is complex for organisations, and existing decision-making models are impractical to make realistic choices. A practical solution must assist a holistic reflection of internal and external BIM success factors. Nevertheless, extant literature is largely focused on software use and awareness. Thus, this paper aims to suggest a novel framework for assessing firm readiness, aimed at facilitating BIM uptake.

Extant explanatory studies are inadequate in assessing the soft nature of BIM uptake. Thus, a design science research was employed as an alternative methodology. A means-end analysis was utilised for solution incubation, and cross-disciplinary reasoning, the strategy to establish valid solutions on firm readiness. Previous studies were reviewed on BIM, technology acceptance (generally) and complexity.

“Technology attitude” is presented as involving more holistic variables than a simplistic reliance on software use to mirror BIM acceptance. Technology acceptance model (TAM) is appropriate to explain BIM attitude attributes, but its current use is sub-optimal. Selective information processing and unconscious thought theory were integrated into TAM to explain attitude formation from multiple perspectives, resulting in a novel BIM attitude scale (BIMAS). Upon verification, the proposed framework will facilitate an objective authentication of biases that associate with BIM acceptance.

Whilst BIM readiness is assessed largely with a primary focus on theory building, practical relevance must be at the forefront of BIM development. This study articulates that design science research can enhance the practical relevance of BIM adoption models. BIM acceptance attitude must be assessed through a verified scale contrary to the assessment of self-biases of executives in literature. BIMAS suggests a testable solution for this. Theory building research must be the future focus to enhance the relevance of this initial solution.

One thing is to get a project organization in place. Another thing is to bring it alive. This is the subject of this chapter. Most project work is teamwork, in the core teams and work groups, and also in the steering committee, reference groups, and focus groups.

Because projects are temporary, it is a challenge quickly to establish effective cooperation in the groups and teams of the project organization, internal as well as external with surrounding organizations. Five elements of cooperation in the project team will be presented, including collaboration, coordination, communication, coalition, and control. Different work patterns will be discussed, and methods for carrying out project work will be presented, e.g., coping with limited rationality and handling project complexity.

A section will deal with work patterns in the steering committee, and a section will discuss cooperation with interested parties (stakeholders). Also, the maturity of the project organization will be treated.

A final section will discuss learning in the project organization.

The purpose of this paper is to emphasise on the need for efficient and effective project risk management practices and to support project managers in increasing the cost certainty of projects by proposing a new framework for project risk management.

The author adopts a “constructivist” methodology, drawing on practices common in construction management sciences and new institutional economics.

The author presents a holistic and customisable project risk management framework that is grounded in both practice and academia. The framework is holistic because, amongst others, all steps of the typical risk management process are addressed. The framework is customisable, because it allows for alternative ways of implementing the project risk management steps depending on the project-specific circumstances.

The framework does not address the potential unwillingness of the project players to set up a project risk management process, at all. The proposed framework has not yet been tested empirically. Future research will seek to validate the framework.

The framework is designed to account for the difficult circumstances of a complex construction project. It is intended to support decision makers in customising a practical yet comprehensive project risk management concept to the characteristics of the unique project. Although many other project risk management concepts are designed based on the assumption that actors are perfectly rational and informed, this framework’s design is based on the opposite assumption. The framework is dynamic and should adapt over time.

Research examining the joint role of serial acquisitions and subsidiary autonomy in holistic value provision within servitizing industrial firms is scarce. Thus, this paper aims to investigate the role of serial acquisition and subsidiary autonomy in providing value within servitizing industrial networks.

A conceptual framework is developed based on the case study of a large Swedish industrial group specializing in selling industrial products and providing industrial solutions to business customers through its numerous subsidiaries.

The analysis of 14 interviews with the five subsidiaries and seven customer firms and secondary data reveals interesting findings concerning the role of serial niche acquisition strategy and subsidiary autonomy in customer value provision in servitizing organizations. In particular, the authors find that the role of acquisitions in industrial firms extends beyond growth to customer sensing and proximity. Likewise, the authors find that subsidiary autonomy facilitates value provision to customers in industrial networks.

The paper provides a more nuanced understanding of how serial acquisitions and subsidiary autonomy are intertwined and jointly affect industrial firms’ value provision activities amidst the servitization transition in an intraorganizational network.
