To design an efficient and integrated framework for automated and simple data acquisition and processing targeted for first response scenarios.
Abstract
Purpose
To design an efficient and integrated framework for automated and simple data acquisition and processing targeted for first response scenarios.
Design/methodology/approach
Utilizes existing software/hardware integration tools and primarily off‐the‐shelf components. Use the modular system architecture for development of new applications. System construction is preceded by the analysis of currently available devices for specific data acquisition and processing.
Findings
The development and integration of data acquisition and processing tools for first responder scenarios can be rapidly achieved by the modular and already existing software/hardware integration platform. Data types processed by this system are biometrics, live video/audio and textual/command data. The data acquisition is followed by the prompt dissemination of information from the incident scene thus overcoming interoperability issues.
Practical implications
Integration of new modules is achieved through simple system upgrades – new applications are created and integrated while the rest of the platform remains intact. Off‐the‐shelf components used eliminate the need for specialized hardware development. The speech user interface allows simple interaction with the system in an eyes‐off, hands‐off manner.
Originality/value
The system represents an efficient platform for integrated data acquisition and processing specially targeted for first response. The test‐bed flexibility allows for straightforward integration of devices/applications handling new data type as required by the user.

Abstract
Purpose
This paper describes the development of a novel automated vision system used to detect the visual defects on painted slates.
Design/methodology/approach
The vision system that has been developed consists of two major components covering the opto‐mechanical and algorithmical aspects of the system. The first component addresses issues including the mechanical implementation and interfacing the inspection system with the development of a fast image processing procedure able to identify visual defects present on the slate surface.
Findings
The inspection system was developed on 400 slates to determine the threshold settings that give the best trade‐off between no false positive triggers and correct defect identification. The developed system was tested on more than 300 fresh slates and the success rate for correct identification of acceptable and defective slates was 99.32 per cent for defect free slates based on 148 samples and 96.91 per cent for defective slates based on 162 samples.
Practical implications
The experimental data indicates that automating the inspection of painted slates can be achieved and installation in a factory is a realistic target. Testing the devised inspection system in a factory‐type environment was an important part of the development process as this enabled us to develop the mechanical system and the image processing algorithm able to perform slate inspection in an industrial environment. The overall performance of the system indicates that the proposed solution can be considered as a replacement for the existing manual inspection system.
Originality/value
The development of a real‐time automated system for inspecting painted slates proved to be a difficult task since the slate surface is dark coloured, glossy, has depth profile non‐uniformities and is being transported at high speeds on a conveyor. In order to address these issues, the system described in this paper proposed a number of novel solutions including the illumination set‐up and the development of multi‐component image‐processing inspection algorithm.

Abstract
Purpose
To report on the evaluation of error of a face matching system consisting of a 3D sensor for obtaining the surface of the face, and a two‐stage matching algorithm that matches the sensed surface to a model surface.
Design/methodology/approach
Rigid mannikin face that was, otherwise, fairly realistic was obtained, and several sensing and matching experiments were performed. Pose position, lighting and face color were controlled.
Findings
The combined sensor‐matching system typically reported correct face surface matches with trimmed RMS error of 0.5 mm or less for a generous volume of parameters, including roll, pitch, yaw, position, lighting, and facecolor. Error accelerated beyond this “approximately frontal” set of parameters. Mannikin results are compared to results with thousands of cases of real faces. The sensor accuracy is not a limiting component of the system, but supports the application well.
Practical implications
The sensor supports the application well (except for the current cost). Equal error rates achieved appear to be practical for face verification.
Originality/value
No similar report is known for sensing faces.

Abstract
Purpose – Movements typically have great difficulty using the mass media to spread their messages to the public, given the media's greater power to impose their frames on movement activities and goals. In this paper, we look at the impact of the political context and media strategies of protesters against the 2009 G-20 meetings in Pittsburgh on media coverage of the protests.
Methodology – We employ field observations, interviews with activists and reporters, and a content analysis of print coverage of the demonstrations by the two local daily newspapers, the Pittsburgh Post-Gazette and the Pittsburgh Tribune-Review.
Findings – We find that protesters were relatively successful in influencing how they were portrayed in local newspaper stories and in developing a sympathetic image of their groups’ members. Specifically, we find that activist frames were present in newspaper coverage and activists were quoted as frequently as city officials.
Research implications – We argue that events such as the G-20 meetings provide protesters with opportunities to gain temporary “standing” with the media. During such times, activists can use tactics and frames to alter the balance of power in relations with the media and the state and to attract positive media coverage, particularly when activists develop strategies that are not exclusively focused on the media. We argue that a combination of political opportunities and activist media strategies enabled protest organizers to position themselves as central figures in the G-20 news story and leverage that position to build media interest, develop relationships with reporters, and influence newspaper coverage.

Abstract
American radical economists in the 1960s perceived China under Maoism as an important experiment in creating a new society, aspects of which they hoped could serve as a model for the developing world. But the knowledge of “actually existing Maoism” was very limited due to the mutual isolation between China and the US. This chapter analyses the First Friendship Delegation of American Radical Political Economists (FFDARPE) to the People’s Republic of China in 1972, consisting mainly of Union for Radical Political Economics (URPE) members, which was the first visit of a group of American economists to China since 1949. Based on interviews with trip participants as well as archival and published material, this chapter studies what we can learn about the engagement with Maoism by American radical economists from their dialogues with Chinese hosts, from their on-the-ground observations, and their reflection upon return. We show how the visitors’ own ideas conflicted and intersected with their perception of the Maoist practice on gender relations, workers’ management, and life in the communes. We also shed light on the diverging conceptions of the role for economic expertise between URPE and late Maoism. As the first in-depth study on the FFDARPE, we provide rich empirical insights into an ice-breaking event in the larger process of normalization in the Sino-US relations, which ultimately led to the disillusionment of the Left with China.

Abstract
Purpose
How do females with multiple sources of identity deal with intersectional identity tensions and perceived lack of access to social power? The study focuses on how social relationships form and develop in masculinised settings between construction workers and a petite female researcher through perceived notions of equality and inequality. Through autoethnographic tales, the study examines how an academic home comer navigates between conflicting professional and cultural identities, in their native country.
Design/methodology/approach
Using collaborative autoethnography, the study examines how the intersections of being a young petite female and a “partial” insider in a male-dominated construction industry influences the researcher's identity work process and her quest for social power.
Findings
The findings suggest that to access referent social power, the researcher covers stigmatised intersectional attributes and reveals a more favourable identity. The fieldwork journey of the young petite female researcher highlights that identity work is a situational process that evolves with respondent relationships, respondent assigned roles, perceived notion of access to power and struggles of cultural versus professional identity. The reader is also taken through the collaborative autoethnographic journey of a female researcher and her doctoral studies supervisor.
Originality/value
This paper makes several contributions. First, it contributes to the academic literature on intersectionality of identity, especially concentrating on the intersectional attributes of petite physical stature, gender and perceived lack of access to social power. Second, this paper theorises identity work processes as an indirect strategy of social power in researcher-and-researched relationships. Last, through collaborative autoethnography of female researchers' fieldwork journey, this study contributes to the body of knowledge on academic home comers as “partial” insiders in their native country.

Abstract
The unjustifiable claims made by manufacturers of a certain class with regard to their products are frequently of a startling character, such claims often being so utterly absurd that in the case of educated persons they serve not to recommend the puffed goods, but rather to hold up the manufacturer who makes such statements to ridicule. False claims and false allegations are always made with one object in view, namely, to obtain money by taking advantage of public ignorance. There are two distinct kinds of false claims and allegations: they may either be unfair and unjustifiable with regard to the properties, uses, and value of the article, or, what is far worse, they may be entirely false allegations as to the purity and genuineness of the product. With regard to the latter practice it is difficult to find words of condemnation sufficiently strong. The manufacturer not only sells an adulterated and inferior article, but boldly makes a statement to the public to the effect that the article is pure and genuine. It is unpardonable that men who claim to be honourable men of commerce should make such statements, knowing full well that the manufacture of the article consists in a process of adulteration. The effect of these malpractices is not only to gull the public, but to cause the manufacturer of products which are really genuine and of good quality to suffer severely. To any reasonable mind it is quite evident that really good and genuine products cannot be sold to compete in price with articles which, despite the strong claims that may be made for them, are inferior and often worthless. The unscrupulous manufacturer is putting money into his own pocket to which he has no right, and which in reality belongs to those who have suffered as the result of dishonest competition.

Abstract
Database marketing is scarcely comprehended by marketing professional practitioners as yet but its potential is becoming clear. It not only revolutionises the productivity of direct marketing but transforms the effectiveness of salesforce prospecting, marketing research and channel management. The evolution of database marketing at MCB University Press is described and analysed over the past 15 years. The intrapreneurial and behavioural dimensions of development and implementation are traced and guidance provided for those who accept that good computer systems grow from within rather than arrive from without the enterprise.
