This paper compares and contrasts online searching on DataStar, a major European host now owned by The Dialog Corporation, using the “Classic” command language, with access via the more recent Web interface. DataStar, established in 1981, was one of the first online hosts to offer a web interface, in December 1996. DataStar Web was upgraded in December 1997. “Classic” DataStar command line searching requires familiarity with commands, operators, database labels, etc. DataStar Web offers searching via apparently simple steps: eg. selecting a database, entering search terms. The functionality of the two interfaces is considered, looking in turn at entering the system, selecting a database, searching, output and display, terminating the search session, error messages and help pages, and support, training and documentation. The search functionality of the two interfaces is not identical, although both use the same retrieval software and access the same databases. Many of the differences affect retrieval effectiveness and may trip up novice and experienced searchers alike.

For several years, the classic car market has been attracting considerable media and public attention, but the research literature is virtually nonexistent. The purpose of this paper is to address the factors that determine the values of classic car models and explain the remarkable price differences among them.

The paper develops and tests a set of research hypotheses about the effects of model characteristics on market values in the context of a generalized hedonic price model that also accounts for heterogeneity among classic car brands.

It is demonstrated that classic car model values reside at several levels and are determined by observable characteristics pertaining to aesthetics, rarity, engineering and performance. In addition, we show that classic car marques play a critical role in the determination of model values and account for considerable variation in values, even after controlling for observable model attributes

This is one of the first empirical studies to address classic car model value formation. The findings reveal how measurable, observable factors determine classic car model values and augment our understanding of a very interesting but understudied market.

The purpose of this paper is to: first, explain why a new model of the provision of welfare services to citizens arises from the digital society; second explore some core elements of the competition between the new model of the provision of welfare services and the classic ideal model of the professionals’ provision of welfare services; third, suggest why it is most likely that the two models of the provision of services are combined into a symbiotic co-evolution scenario; and fourth, examine why and how this symbiotic co-evolution scenario results in new participatory spaces for the main actors associated with the provision of welfare services.

The review of the literature examines how the new model for the provision of welfare services facilitated by big data challenges the traditional professional model for the provision of welfare services. The authors use the Danish case to illustrate a number of themes related to this looking at the hospital sector as an example.

The proposition is that a symbiotic co-evolution scenario will emerge. A mix of the classic ideal model and practice of the service professionals’ provision of services and the digital society’s model of the provision of services is the most likely scenario in the years to come. Furthermore, Data-driven management (DDM) as an integrated key element in a symbiotic co-evolution creates (opens up) participatory environments and spaces for the main actors and agents associated with the provision of welfare services to the citizens.

DDM’s impact on the provision of welfare services is still being realised and worked out, and more empirical research is needed before it is possible to point at the most likely scenario. However, according to the authors’ analytical framework, the institutional logics perspective, as presented in Section 2, a symbiotic co-evolution is most likely such that DDM will constitute a new logic within the provision of welfare services on the basis of which citizens as end-users could be provided with welfare services, but it is not likely that the new logic of DDM can displace the classic service professionals’ model of the provision of welfare services. Therefore, the new logic of DDM will be combined with and integrated into the existing logics within service provision, such as the Weberian bureaucracy, the Street-Level Bureaucracy, the New Public Governance and the Market. In spite of this, DDM can successfully be promoted by international management consulting firms, as a management concept which can remedy all the problems of the classic service professionals’ model of the provision of welfare services to citizens.

As a consequence of this, new relationships among professionals, data analytics, (middle) managers and citizens will be created regarding the provision of welfare services. Considering the new participatory environments and spaces and the new relationships among the classic service professionals, the data analytics, the (middle) managers and the citizens as end-users, the provision of welfare services may become an arena for negotiation of a new future model of the provision of welfare services to citizens.

The digital society has emerged from and developed further via: digitising, online information in almost real time, algorithms, data-informed decision-making processes, DDM and, ultimately, big data. The authors expect to see further digitising, more sophisticated algorithms and more big data. The authors suggest that a new model of the provision of welfare services to citizens will emerge from the development of the digital society. The authors also suggest that this new model will compete with the classic model of the provision of welfare services.

Contends that most collections of classic works are the result, primarily, of subjective criteria applied by one editor or a small group of editors. Provides a list of authors and classic works in the field of production and operations management (POM) arrived at by applying more objective criteria. Maintains that this listing was developed, not from the preferences of the researchers, but rather on the basis of results of a survey of those persons most involved in the field: POM educators and scholars.

The most powerful and effective forces of hierarchizing are those that naturalize difference so that it is beyond dispute and something to be tacitly accepted. In the Classic Maya world, this “social speciation” was materialized and naturalized through a complex web of ritual practice, deity emulation, enhancement of body aesthetics, and the fabrication and possession of hypertrophic goods. The architecture of Classic Maya royal courts broke with an older Maya residential pattern of accretional construction filled with ancestral burials in order to materialize more effectively social difference, to provide space for exclusive ritual performance, and to showcase the highly valued and gendered labor of textile production. Such instruments of authority are “weapons of exclusion” that can be wielded to fend off assaults on hierarchy. From this perspective, informed by the ritual economy approach, the profound transformations of the 9th century in the Maya lowlands are considered an assault that was not defendable.

This paper is the third part of a series of works investigating the top 100 knowledge management (KM) citation classic articles. The purpose of this paper is to understand why KM citation classics are well-cited.

The results of a survey of 58 KM citation classic authors were reported as descriptive statistics and subjected to content analysis.

An archetype of a KM citation classic author was constructed including demographics, personal characteristics, motivation and work preferences. There is a need for developing novel ideas in KM research. Timeliness of a publication is directly linked to its future impact. Editors should involve citation classics authors as reviewers, and KM researchers should improve their citation practices. Serendipity played a very important role in early KM research, especially from the perspective of discovering new and interesting phenomena.

Whereas the importance of serendipity is not questioned, future KM researchers should rely more on a formal, meticulous and well-planned research approach rather than on the hope of making a discovery by accident or luck. KM citation classics authors relied on serendipity to form the foundation of the discipline, but extending their work requires formal and structured inquiries.

Many authors conducted research to solve a problem to serve the needs of both practice and academia, rather than being overly theoretical.

Because KM researchers can no longer rely on past bibliometric theories, this paper helps understand why specific articles are highly cited and recommends how to conduct and develop future KM research that has impact.

This paper aims to emphasize compared experimental analysis of influence of hybrid and classic moulds on the properties of moulded parts and the processing parameters. Such analysis enables optimization of processing parameters in case of the hybrid mould.

Representative moulded part and appropriate hybrid and classic moulds have been designed and manufactured. The experimental work contains a screening design and the main central composite design for analysing the performance of both moulds and moulded parts properties. In case of hybrid mould a numerical optimization of processing parameters was used.

It was found that hybrid moulds can be successfully applied for production of thin‐wall moulded parts with some limitations. The compressibility of prototype mould inserts was higher compared to classic inserts. The differences in thermal properties of mould inserts materials result in different moulded part properties and mould cavity wall temperature fields. These differences can be reduced by optimizing the processing parameters.

RT technologies can be usefully applied for fast production of moulds for injection moulding. The potential user of hybrid moulds should be aware of the influence of prototype inserts on the moulded part properties. Guidelines for optimization can be used for fast achieving of parameters from optimal processing window.

This paper shows a detailed analysis of influence of hybrid and classic moulds on the thermoplastic moulded part properties. Some of these influences are explained in detail, which was not found in the related papers. In this paper, a further step was made by optimizing the processing parameters in case of hybrid mould.

Prior research has demonstrated that investment management performance fees have the characteristic of a call option. It is important to examine whether these performance fees are consistent with traditional fee structures used by investment managers. It is also worth examining whether clients or managers benefit significantly more than the other party under performance fee structures. The paper aims to discuss these issues.

The authors use Black-Scholes options pricing methodology to examine three cases of performance fee structures. The Absolute Hurdle case examines the fee structure where the manager receives a portion of the return over a pre-defined absolute rate of return. The Benchmark Relative Hurdle case shows a fee structure based on performance in excess of the return of a benchmark portfolio. The Breakeven Relative Hurdle case illustrates the fee structure where there is revenue neutrality with the classic management fees when portfolio performance matches the benchmark.

The findings of this paper illustrate that a particular performance fee structure can be designed to have the same revenue as a traditional investment management fee structure. Such a structure is equally beneficial to both the investment manager and to the client and should have salutary motivational effects to improve investment results, while simultaneously rewarding the manager for value added at a fair price for both the manager and the investor.

This study is unique in that it examines three cases of performance fees and provides a comparison between performance fee structures and traditional investment management fee structures. The findings will assist investment portfolio managers in better setting management fees they charge clients. In addition, this study help with clients who feel they are being charged excessive management fees by their investment manager.

In most applications the active power filters (APFs) are used to reduce harmonic distortion of a nonlinear load which is located near the APF installation point. This classic approach allows to reduce the distortion introduced to the power system but do not guarantee that the cost of the APFs installation is optimal. The purpose of this paper is to compare the classic approach to harmonic compensation with an optimization method of sizing and placement of the APFs in an existing distributed power network.

An exemplary real-life power system with distributed nonlinear loads was modeled using PCFLO power analysis software. Next, Matlab was used to implement the classic method and the optimization algorithm. Between Matlab and PCFLO a specially written Java middleware was used to provide a seamless workflow integration.

It was shown that the presented optimization method may lead to superior results in comparison with the classic approach. Simulation results clearly showed that the APFs installation cost can be significantly reduced when the optimization algorithm is used. Moreover, the proposed optimization method can overcome some problems connected with the nonlinearity and discontinuity of the APF's price/current function.

There are two main limitations of the presented method. First, the method needs much more computing power then the classic approach. Second, according to the authors’ knowledge, currently there are no commercially available APFs, which allow to directly apply the optimization method in industrial applications.

The presented results showed that the approach, which is the most popular in the industry, is far from being optimal from the cost perspective. As it has been shown in the investigated example, it might be possible to significantly reduce the total cost of APFs installed in the power system.

The optimization method presented in the paper as well as all simulation results are the original authors work. It was shown that the existing harmonic compensation strategies can be significantly upgraded and the proposed optimization method may be a basis and a reference point for future commercial solutions.

The purpose of this paper is to argue for the need of continuously revisiting and reformulating the contributions of past research. In particular the focus is on project management writings. In addition, the purpose of the paper is to introduce the reader to the special issue on Classics in project management and give an overview of the different contributions.

The paper is based on literature in related fields and the approach is paradigmatic, illustrating the value of common literature and common language to develop a knowledge domain.

The authors provide an introductory framework and arguments for the need to revisit the contributions of the past. Since “the past” and readings of it will continuously change and develop, exploring it is not a “one‐off” job, but part of the dialogue within the academic community. From an evolutionary perspective, the authors make the point that an important role for scholars is to “store” knowledge from the past to tell the stories found in prior research, the influential ideas and their development within the knowledge domain/discipline. In a critical realm, the authors also see the role of critical engagement with the past to question what we take for granted to be able to improve our collective ability to think and from that end develop project management thinking and research. In that sense, revisiting the past might provide avenues to future research and adventurous explorations.

The authors introduce the idea of classics in project management as an ongoing and important debate among scholars within the field. This discussion has so far received only limited attention among scholars in the field of project management.
