Abstract

Purpose

The paper provides a detailed description of standard procedures for constructing facial composites. These procedures are relevant to forensic practice and are contained in the technical papers of this special issue; the purpose of this paper is also to provide an expanding reference of procedures for future research on facial composites and facial-composite systems.

Design/methodology/approach

A detailed account is given of the interaction between practitioner and witness for producing a facial composite. This account involves an overview of the Cognitive Interview (CI) and the Holistic CI (H-CI) techniques used to obtain a description of the face of an offender (target); the authors then describe how this information is used to produce a composite from five popular face-production systems: Sketch, PRO-fit, Electronic Facial Identification Technique (E-FIT), EvoFIT and EFIT-V. An online annex is also made available to provide procedural information for additional composite systems.

Practical implications

The work is valuable to forensic practitioners and researchers as a reference for interviewing techniques (involving a CI or an H-CI) and using facial-composite systems.

Originality/value

The authors provide an accessible, current guide for how to administer interviewing techniques and how to construct composites from a range of face-production systems.

Abstract

Purpose

The purpose of this paper is to investigate whether the presence of a whole-face context during facial composite production facilitates construction of facial composite images.

Design/methodology/approach

In Experiment 1, constructors viewed a celebrity face and then developed a facial composite using PRO-fit software in one of two conditions: either the full-face was visible while facial features were selected, or only the feature currently being selected. The composites were named by different participants. The authors then replicated the study using a more forensically valid procedure: in Experiment 2 non-football fans viewed an image of a premiership footballer and 24 hours later constructed a composite of the face with a trained software operator. The resulting composites were named by football fans.

Findings

In both studies, the presence of the facial context promoted more identifiable facial composites.

Research limitations/implications

Current composite software was deployed in a conventional and unconventional way to demonstrate the importance of facial context.

Practical implications

Results confirm that composite software should have the whole-face context visible to witnesses throughout construction. Although some software systems do this, there remain others that present features in isolation and these findings show that these systems are unlikely to be optimal.

Originality/value

This is the first study to demonstrate the importance of a full-face context for the construction of facial composite images. Results are valuable to police forces and developers of composite software.

Abstract

Purpose

The introduction of a three-quarter-view database in the PRO-fit facial-composite system has enabled an investigation into the effects of image view in face construction. The purpose of this paper is to examine the impact of constructing full-face and three-quarter-view composites under different encoding conditions. It also examines the potential value of three-quarter-view composites that can be generated automatically from a front-view composite. The authors also investigate whether there is an identification benefit for presenting full-face and three-quarter composites together.

Design/methodology/approach

Three experiments examine the impact of encoding conditions on composite construction and presentation of composites at the evaluation stage.

Findings

The work revealed that while standard full-face composites perform well when all views of the face have been encoded, care should be taken when a person has only seen one view. When a witness has seen a side view of a suspect, a three-quarter-view composite should be constructed. Also, it would be beneficial for a witness to construct two composites of a suspect, one in full-face view and one in a three-quarter-view, particularly when the witness has only encoded one view. No benefit emerged for use of three-quarter-view composites generated automatically.

Research limitations/implications

This is the first study to examine viewpoint in facial composite construction. While a great deal of research has examined viewpoint dependency in face recognition tasks, composite construction is a reconstruction task involving both recall and recognition. The results indicate that there is a viewpoint effect that is similar to that described in the recognition literature. However, more research is needed in this area.

Practical implications

The practical implications of this research are that it is extremely important for facial composite operators in the field (police operators) to know who will make a good likeness of the target. Research such as this which examines real-life issues is incredibly important. This research shows that if a witness has seen all views of a perpetrator’s face then standard composite construction using a full-face view will work well. However, if they have only seen a single view then it will not.

Social implications

There are obvious wider societal implications for any research which deals with eyewitness memory and the potential identification of perpetrators.

Originality/value

No research to date has formally examined the impact of viewpoint in facial-composite construction.

Abstract

Purpose

The purpose of this paper is to assess the impact of seven variables that emerge from forensic research on facial-composite construction and naming using contemporary police systems: EvoFIT, Feature and Sketch.

Design/methodology/approach

The paper involves regression- and meta-analyses on composite-naming data from 23 studies that have followed procedures used by police practitioners for forensic face construction. The corpus for analyses contains 6,464 individual naming responses from 1,069 participants in 41 experimental conditions.

Findings

The analyses reveal that composites constructed from the holistic EvoFIT system were over four-times more identifiable than composites from “Feature” (E-FIT and PRO-fit) and Sketch systems; Sketch was somewhat more effective than Feature systems. EvoFIT was more effective when internal features were created before rather than after selecting hair and the other (blurred) external features. Adding questions about the global appearance of the face (as part of the holistic-cognitive interview (H-CI)) gives a valuable improvement in naming over the standard face-recall cognitive interview (CI) for all three system types tested. The analysis also confirmed that composites were considerably less effective when constructed from a long (one to two days) compared with a short (0-3.5 hours) retention interval.

Practical implications

Variables were assessed that are of importance to forensic practitioners who construct composites with witnesses and victims of crime.

Originality/value

Using a large corpus of forensically-relevant data, the main result is that EvoFIT using the internal-features method of construction is superior; an H-CI administered prior to face construction is also advantageous (cf. face-recall CI) for EvoFIT as well as for two further contrasting production systems.

Abstract

Purpose

The purpose of this paper is to investigate the potential susceptibility of eyewitness memory to the presence of extraneous background speech that comprises a description consistent with, or at odds with, a target face.

Design/methodology/approach

A between-participants design was deployed whereby participants viewed an unfamiliar target face in the presence of quiet, or extraneous to-be-ignored speech comprising a verbal description that was either congruent or incongruent with the target face. After a short distractor task, participants were asked to describe the target face and construct a composite of the face using PRO-fit software. Further participants rated the likeness of the composites to the target.

Findings

Recall of correct facial descriptors was facilitated by congruent to-be-ignored speech and inhibited by incongruent to-be-ignored speech compared to quiet. Moreover, incorrect facial descriptors were reported more often in the incongruent speech condition compared with the congruent speech and quiet conditions. Composites constructed after exposure to incongruent speech were rated as worse likenesses to the target than those created after exposure to congruent speech and quiet. Whether congruent speech facilitated or impaired composite construction was found to depend on the distinctiveness of the target face.

Practical implications

The results suggest that the nature of to-be-ignored background speech has powerful effects on the accuracy of information verbally reported from having witnessed a face. Incongruent speech appears to disrupt the recognition processes that underpin face construction while congruent speech may have facilitative or detrimental effects on this process, depending on the distinctiveness of the target face.

Originality/value

This is one of the first studies to demonstrate that extraneous speech can produce adverse effects on the recall and recognition of complex visual information: in this case, the appearance of a human face.

Abstract

Purpose

This paper aims to contribute to extant research which emphasises the need for service suppliers to be able to leverage firm‐customer relationships through an understanding of the correlation between service touch‐points and engagement parameters.

Design/methodology/approach

The authors utilised multivariate methods (CATPCA and Pro‐fit) to analyse the data. Data were collected through a questionnaire survey of 238 respondents, sampled through the social networking site, “Facebook”.

Findings

It was found from the analysis of data that within the context of customer engagement, four critical parameters (“satisfaction”, “loyalty/advocacy”, “recruitment/retention” and “customer losses”) impact on customer touch‐points.

Research limitations/implications

The study is characterised by two limitations. The first is that the respondents' simultaneous utilisation of multiple touch‐points was not accounted for in the study. Second, the authors acknowledge that the narrow demographic spread of the respondents is a possible limitation of the study.

Originality/value

The study findings are grounded in empirical findings which is a departure from traditional scholarship on customer touch‐points which has been based on case observations and anecdotal evidence.

Abstract

This paper discusses the identification and measurement of intangible assets in the public sector. A discussion of intellectual capital theory identifies and classifies a number of intangible assets of relevance to the public sector. Multidimensional scaling and related multivariate techniques are proposed for their detection and quantification. The methodology is illustrated with a case study: the provision of council services through the Internet by Spanish municipalities. The technique identifies three intangible assets related to external structural capital: service, image and transparency. Five strategic groups reveal the different objectives, strategic use of the Internet, and actions taken by the various Spanish councils.

Abstract

Most of the largest UK supermarket chains are very successful; they have strong cash balances and generate large profits. The writer asserts that it is in the areas of strong centralised control over margins, stock levels, cash flow and good lines of communication that supermarket chains have developed highly sophisticated control systems. This article looks at some of the larger supermarket chains in terms of margins and returns, working capital, labour, and the accountant's role in communication and control. It is an abridged version of an article which originally appeared in “Accountancy”, and is reproduced here with their permission.

Abstract

Purpose

The purpose of this paper is to describe an empirical study of the advances and trends of e‐government in transparency, openness and hence accountability in European Union (EU) local governments to determine the extent to which the internet promotes the convergence towards more transparent and accountable government. The paper also tests the extent to which different factors related to the implementation of information and communication technologies (ICTs), the number of inhabitants and the type of public administration style have influenced e‐government developments in the cities studied.

Design/methodology/approach

A comprehensive content analysis of 75 local government web sites was conducted using a 73‐item evaluation questionnaire. The evaluations were performed in 2004 and 2007 and 15 EU countries were covered (five per country). To analyse the evolution of e‐government, several techniques were used: tests of difference of means, multidimensional scaling and cluster analysis. The contribution of the different contextual factors to the development of government web sites was tested with OLS regression analysis.

Findings

The results show noticeable progress in the application of ICTs and increasing EU local government concern for bringing government closer to citizens and for giving an image of modernity and responsiveness, although few web sites show clear signs of real openness to encouraging citizen dialogue. The evolution of the e‐government initiatives analysed shows that, at present, they are still overlapped with the public administration style of each country as an extension of traditional front offices with potential benefits in speed and accessibility.

Originality/value

Although a growing number of e‐government studies are appearing, previous research has not analysed the evolution of EU local governments from a comparative perspective.
