Abstract
Purpose
This paper aims to discuss the development of a defect classification system that can be used to detect and classify powder bed surface defects from captured layer images without the need for specialised computational hardware. The idea is to develop this system by making use of more traditional machine learning (ML) models instead of using computationally intensive deep learning (DL) models.
Design/methodology/approach
The approach that is used by this study is to use traditional image processing and classification techniques that can be applied to captured layer images to detect and classify defects without the need for DL algorithms.
Findings
The study proved that a defect classification algorithm could be developed by making use of traditional ML models with a high degree of accuracy and the images could be processed at higher speeds than typically reported in literature when making use of DL models.
Originality/value
This paper addresses a need that has been identified for a high-speed defect classification algorithm that can detect and classify defects without the need for specialised hardware that is typically used when making use of DL technologies. This is because when developing closed-loop feedback systems for these additive manufacturing machines, it is important to detect and classify defects without inducing additional delays to the control system.

Abstract
A century ago, military instruments were readily deployed in imperialistic adventures or the defence of national interests. Today the strategic environment is more complex and diplomatic protocols more established. The information revolution is meanwhile telescoping time frames and proliferating futures scenarios. But even if the politicians are driving the agenda, the security imperative remains the same. For defence planners that implies new models and mechanisms, and a closer nexus in the formulation of political and defence policy.

Abstract
Presents over sixty abstracts summarising the 1999 Employment Research Unit annual conference held at the University of Cardiff. Explores the multiple impacts of globalization on work and employment in contemporary organizations. Covers the human resource management implications of organizational responses to globalization. Examines the theoretical, methodological, empirical and comparative issues pertaining to competitiveness and the management of human resources, the impact of organisational strategies and international production on the workplace, the organization of labour markets, human resource development, cultural change in organisations, trade union responses, and trans‐national corporations. Cites many case studies showing how globalization has brought a lot of opportunities together with much change both to the employee and the employer. Considers the threats to existing cultures, structures and systems.

Abstract
In this chapter we develop sustainability implications of the Savall, Zardet, Bonett, and colleagues’ approach, known worldwide as socioeconomic approach to management (SEAM). SEAM can be used as a way of doing management and organizational inquiry into the ecological sustainability of practices with planetary boundaries. We conclude that a socially responsible approach to management needs to consider the hidden costs to an enterprise if it is not being sustainable to planetary resource limits.

Abstract
This chapter attempts to offer a clearer look at the historical roots of the founding of mutualist finance. Without denying that the various forms of financial mutualism may have legal and organizational roots in ancient times, the author considers what, for contemporary mutualist banks, may constitute the soul.
In its first part, the document presents the individual constructions that existed in the eighteenth and nineteenth centuries, in a context in which economic development and the industrial revolution banished the rules and standards of the former society. It refers to Utopian socialisms as opposed to the scientific solutions proposed for a new social organization and to the new solidarism according to Léon Bourgeois. Christian sources are also called to mind with social Christianity (Protestant) and social Catholicism until the birth of the social doctrine of the Church.
This frenzy of ideas as well as the confrontation with reality led to the birth, in Germany, of the first experiments with alternative finance. This is the subject of the second part of this chapter, which then develops the bank mutualism created by the founding fathers, F.W. Raiffeisen and H. Schulze-Delitzsch.
The historical description of the creation of mutualist banks brings up two major problems when talking about the “other finance”: the interest and activity of the bank. Is an ethical finance capable of proposing a credible alternative? This is a question that needs to be answered in the light of history.
This chapter attempts, more than 150 years after the fact, to demonstrate the ponderous presence of the question and the permanence of the founding ideas in order to comprehend the facts and propose ideas for analysis and construction of an “other finance.”

Abstract
This paper seeks to understand how a new elite, known as the cork aristocracy, emerged in the Bordeaux wine field, France, between 1850 and 1929 as wine merchants replaced aristocrats. Classic class and status perspectives, and their distinctive social closure dynamics, are mobilized to illuminate the individual and organizational transformations that affected elite wineries grouped in an emerging classification of the Bordeaux best wines. We build on a wealth of archives and historical ethnography techniques to surface complex status and organizational dynamics that reveal how financiers and industrialists intermediated this transition and how organizations are deeply interwoven into social change.

Abstract
Purpose — In the context of evaluating transportation and carbon emission policies, improve weekly activity and mobility scheduling survey methodology in order to enhance data quality while reducing costs and decreasing respondent burden for designing continuous self-administered surveys that are predominantly passive (or computer-assisted).
Approach — Evaluate a set of functionalities deployed in a web travel survey interface (2009) and compare with a pencil-and-paper survey (2002–2003) deployed in Quebec City that sought similar data about weekly mobility. The first used a pencil-and-paper approach complemented by interviews and telecommunications. The second used applets developed in Java, and Google Maps in order to assist geocoding of activity places and the reporting of actual trips into a relational database, while using email to recruit and support respondents.
Implications — Both of these surveys had to address specific technical and privacy challenges during deployment, making their comparison relevant for discussing some of the impacts of information technologies on spatiotemporal data quality, conviviality of survey procedure, respondents' motivation and privacy protection.
Limitations — While neither of these surveys employed movement-aware mobile devices, such as GPS loggers, some of the lessons learnt are relevant to the design issues raised by the increasing deployment of such devices in travel surveys, and by the growing need to manage complex surveys over extended observation periods.
