Abstract

Purpose

The purpose of this paper is to present a new approach toward automatically visualizing Linked Open Data (LOD) through metadata analysis.

Design/methodology/approach

By focussing on the data within a LOD dataset, the authors can infer its structure in a much better way than current approaches, generating more intuitive models to progress toward visual representations.

Findings

With no technical knowledge required, focussing on metadata properties from a semantically annotated dataset could lead to automatically generated charts that allow to understand the dataset in an exploratory manner. Through interactive visualizations, users can navigate LOD sources using a natural approach, in order to save time and resources when dealing with an unknown resource for the first time.

Research limitations/implications

This approach is suitable for available SPARQL endpoints and could be extended for resource description framework dumps loaded locally.

Originality/value

Most works dealing with LOD visualization are customized for a specific domain or dataset. This paper proposes a generic approach based on traditional data visualization and exploratory data analysis literature.

Abstract

The discovery of the Hall‐Herqult process for the manufacture of aluminium made it possible to obtain the metal in large quantities. Soon it attained the position of a major industrial metal due to its lightness combined with strength, capacity to take up a high polish, excellent conductivity of heat and electricity. Moreover it gives a wide range of extremely valuable alloys with diverse elements such as copper, magnesium, nickel, silicon, zinc, etc.

Abstract

Purpose

Provide a secure solution for web services (WS). A new interoperable and distributed access control for WS is presented.

Design/methodology/approach

Based on the separation of the access control (AC) and authorization function.

Findings

Mechanisms presented allow seamless integration of external authorization entities in the AC system. The Semantic Policy Language (SPL) developed facilitates specification of policies and semantic policy validation. SPL specifications are modular and can be composed without ambiguity. Also addressed was the problem of the association of policies to resources (WS or their operations) in a dynamic, flexible and automated way.

Research limitations/implications

The ACProxy component is currently under development. Ongoing work is focused on achieving a richer “use control” for some types of WS.

Practical implications

Administrators of WS can specify AC policies and validate them to find syntactic and semantic errors. Components for automated validation of policies at different levels are included. This ensures that the AC policies produce the desired effects, facilitating the creation and maintenance of policies. It also provides mechanisms for the use of interoperable authorizations.

Originality/value

A practical system that provides a secure solution to AC for WS. To the best of one's knowledge, no other system provides mechanisms for semantic validation of policies based on external authorization entities. Likewise, the mechanisms for interoperability of external authorization entities are also novel. The system provides content‐based access control and a secure, decentralized and dynamic solution for authorization that facilitates the management of complex systems and enhances the overall security of the AC.

Abstract

Purpose

The purpose of this paper is to analyze the effect of a systematic commissioning process on project management performance of construction projects, expressed as cost, time, quality and customer satisfaction. The building commissioner in focus uses the term systematic completion (SC), defining it as a structured process, throughout the whole project assuring the fulfillment of functional requirements in the building.

Design/methodology/approach

A qualitative single case study was used to analyze the effect of a SC process by one Norwegian building commissioner in the public sector, exemplified with four projects. The analysis was conducted by studying project documents and conducting interviews.

Findings

SC has a positive effect on the performance of a construction project, enabling completion on cost, schedule and with fewer defects at handover. Involving facility management assures mutual learning, trained operations personnel and potentially lower costs of operations because of fewer corrections and optimized systems. Higher efforts and resource use in the early phases of the project and in testing are largely offset by the generated benefits.

Research limitations/implications

This case study is limited to the building commissioner’s perspective in four projects. The design team’s, the contractor’s and the client’s perspectives are not represented in the study. Only one of the projects is completed, which limits the ability to draw quantitative conclusions.

Originality/value

Existing studies focus on the technical aspect of SC. The present study provides valuable insights into the effect of SC on project management performance, especially on its implications for the takeover of the building by operations.

Abstract

Of milk alone no less than 36,000 samples were purchased during 1904, almost as many as the total for all articles 10 years ago. Of these 4,031 (or 11.1 per cent.) were returned as adulterated. In the previous year 10.4 per cent. were condemned. The difference is not of necessity due to any increase in adulteration, as the figures are admittedly inaccurate owing to the differences of procedure on the part of Public Analysts in making out their reports. In support of this view it is mentioned that in 14 Metropolitan Districts where 6,270 milks were examined, 4.9 per cent. were reported as containing percentages of added water under 5 per cent., while in 15 other districts, where 3,205 samples were submitted, only 0.56 per cent. were returned as being adulterated to this extent. The explanation is that in the former case the Public Analyst adhered more or less rigidly to the standard fixed by the “Sale of Milk Regulations,” while in the latter, in most instances, where the amount of adulteration was under 5 per cent., the samples were reported as genuine. Here the Report takes what is a more or less new and certainly welcome departure, in definitely expressing an opinion for the guidance of those in doubt, and stating that so long as the “Sale of Milk Regulations” remains in force, “Public Analysts have no warrant for the adoption of a still lower standard.”

Abstract

Purpose

Matching relevant ontology data for integration is vitally important as the amount of ontology data increases along with the evolving Semantic web, in which data are published from different individuals or organizations in a decentralized environment. For any domain that has developed a suitable ontology, its ontology annotated data (or simply ontology data) from different sources often overlaps and needs to be integrated. The purpose of this paper is to develop intelligent web ontology data matching method and framework for data integration.

Design/methodology/approach

This paper develops an intelligent matching method to solve the issue of ontology data matching. Based on the matching method, it also proposes a flexible peer‐to‐peer framework to address the issue of ontology data integration in a distributed Semantic web environment.

Findings

The proposed matching method is different from existing data matching or merging methods applied to data warehouse in that it employs a machine learning approach and more similarity measurements by exploring ontology features.

Research limitations/implications

The proposed method and framework will be further tested for some more complicated real cases in the future.

Originality/value

The experiments show that this proposed intelligent matching method increases ontology data matching accuracy.

Abstract

This paper explores the link between sexual offending and antisocial personality. Drawing on previous research, it illustrates that sex offenders with an antisocial personality are a heterogeneous group, differentiated by several factors. They victimise children, adults or both, those who victimise adults or adults and children are more psychopathic. They are motivated primarily by non‐sexual factors like opportunistic impulsivity or generalised anger, and violence is a source of erotic pleasure in some cases. A small group of men, however, are driven to offend by sadistic sexual fantasies of a serious nature, which develop over time and later form the basis of their violent predatory assaults. Varying definitions of antisocial personality confuse the research, and diagnostic co‐morbidity means that pure psychopathic types are probably rare.

The purpose of this study is to investigate whether sexual homicide offenders (SHO) who dispose of the victim’s body naked present with particular crime scene characteristics.

Abstract

Purpose

The purpose of this study is to investigate whether sexual homicide offenders (SHO) who dispose of the victim’s body naked present with particular crime scene characteristics.

Design/methodology/approach

This study aims to answer this question through the use of a sequential logistic regression to test the individual effects of each set of crime scene variables against the manner of disposal using a sample of 662 solved cases of extrafamilial sexual homicide from an international database.

Findings

Results demonstrated that the modus operandi behaviors of sexual penetration, asphyxiation, dismemberment and overkill were significantly associated with the body being disposed of naked. In addition, removing or destroying evidence from the scene was also significantly associated with a naked victim. In contrast, the body was more likely to be dumped clothed if the contact scene was deserted and the victim was a stranger. These results suggest that SHOs who dispose of the body naked are more in line with the sadistic sexual murderer, while clothed victims are often disposed of by angry offenders.

Originality/value

To the best of the authors’ knowledge, this is the first study to examine the particular manner of disposing the victim’s body naked in cases of sexual homicide.

Abstract

Oil Terminal Protection. The cathodic protection design for the piling of the new North Pier, Mina al‐Ahmadi, Kuwait, consists basically of silicon anodes. The piles are coated with a coal‐tar enamel and the steel superstructure is coated with chlorinated‐rubber paint. Consideration was given to the filling of the piles with water or oil to prevent internal corrosion, but in view of possible damage to piles and loss of liquid they were filled with a sand‐cement mix.
