Abstract
Purpose
The purpose of this paper is to develop an intelligent robot assembly system for the moving production line. Moving production lines are widely used in many manufacturing factories, including automotive and general industries. Industrial robots are hardly used to perform any tasks on the moving production lines. One of the main reasons is that it is difficult for conventional industrial robots to adjust to any sort of change. Therefore, more intelligent industrial robotic systems have to be developed to adopt the random motion of the moving production lines. This paper presents an intelligent robotics system that performs an assembly process while the object is moving, using synergic combination of visual servoing and force control technology.
Design/methodology/approach
The developed intelligent robotic system includes some rules to ensure the success of the assembly processes. Also visual servoing and force control are used to deal with the random motion of the moving objects. Since the objects on the moving production lines are moving with random speed, visual servoing is adopted to tracking the motion of the moving object. Force control is also integrated to control the motion of the robot and keep the robotic system compliant with the moving objects to avoid the damage of the whole system.
Findings
The developed intelligent robotic technology has been successfully implemented. The wheel loading process is used as example.
Research limitations/implications
Since the developed technology is based on the low‐level motion control, safety has to be considered. Currently, it is done by motion supervision.
Practical implications
The developed technology can be used to perform assemblies in the moving production lines. Since the developed platform is based on the synergic combination of visual servoing and force control technology, it can be used in other areas, such as seam tracking and seat loading, etc.
Originality/value
This paper provides a practical solution of performing assemblies on the moving production lines, which is not available on the current industrial robot market.

Abstract
Purpose—Through a case study of Pan American World Airways (Pan Am), this chapter sets out to explore the roots of 20th century globalization and the postcolonial nature of the trading relations involved.
Design/methodology/approach—Drawing on Foucault’s broad notion of “the archive” a critical hermeneutics approach is used to examine a series of company-produced texts, including minutes, travelogues, company narratives, annual reports, film, diaries, and published histories.
Findings—The chapter argues that Pan Am contributed to the “idea of Latin America” and, in the process contributed to practices of dependency that served the interests of the United States. Drawing on a case study of Pan Am, the chapter further argues that multi-national corporations help to establish the contours of international trade by influencing the very character and boundaries of the territories traded in, with troubling implications for the countries traded in.
Research limitations/implications—As a detailed case study extension of the findings to other global trading arrangements needs to take into account to social-political context and relational histories of the players involved.
Practical implications—The chapter generates insights into the role of rhetoric in developing trading relationships and its roots in embedded notions of postcolonial thinking and generalizations.
Originality/value—The chapter contributes to an understanding of the role of language and the social construction of national identities involved in the development of international business.

Abstract
Purpose
The purpose of this paper is to understand the impact of the Great Recession on the capital assets being depreciated and the capital assets condition ratio for the governmental activities of the government-wide financial statements, while identifying possible socioeconomic and financial variables that help explain capital investment behavior in local government.
Design/methodology/approach
Based on capital spending from fiscal year 2005–2006 (FY06) to fiscal year 2012–2013 (FY13) for the governmental activities of 471 North Carolina municipalities as reported on their government-wide financial statements, the authors use a fixed effects model to test our two hypotheses.
Findings
The authors find that most municipalities consistently invested in capital assets before, during, and after the Great Recession but were not able to maintain pace with depreciation. The authors also find that the capital assets being depreciated is affected by numerous socioeconomic and financial variables, while the capital assets condition ratio is not.
Research limitations/implications
The study continues to build on previous research, demonstrating that different results are produced when the analysis is based on local data rather than sub-national data.
Practical implications
An implication from our study that expands across research and practice is that capital investment and capital value are two different dimensions of capital management in local government, which drives research in terms of how this multidimensional concept is specified and drives practices in terms of how this multidimensional concept is approached within annual capital budgets and capital improvement programs.
Originality/value
The study represents one of the first studies that focuses on capital spending in local government based on data from the government-wide financial statements.

Abstract
Unfortunately, I am not the first to attempt to map out the narrative terrain of Others. In 1985, R. S. Perinbanayagam presented various social theorists’ conceptions of the Other in his book Signifying Acts: Structure and Meaning in Everyday Life. Basically, they comprise three Others: the Generalized Other, the Meiotic Other (my language), and the Significant Other. I will address three additional Others – the Unconscious Other, the Marginalized Other, and the Nonhuman Other – that I find in a broader and more recent literature. Although I group them into six main Others, the borders of these types are somewhat arbitrary, porous, and nondiscrete, as interaction and intersection exist among them. Two characteristics that distinguish one Other from another are whether the Other exists within or outside the Self and whether the Other is an individual or aggregate entity. The Unconscious Other and the Generalized Other both are constructed from symbolic material outside the individual but ultimately take up residence within the Self. The Meiotic Self is the self-divided; there may be multiple divisions but each Meiotic Self is usually presented as singly constituted. The Significant Other, an individual, and the Marginalized Other, often a status group or member of it, reside outside the Self but play supporting roles in relation to any particular Self, which may also be an individual or status group, such as men, Whites, and Americans. The Nonhuman Other may be individual, an aggregate of individuals, or the product of human behavior, all of which reside outside the Self.

Abstract
This paper surveys theoretical and practical issues associated with a particular type of information retrieval problem, namely that where the information need is pictorial. The paper is contextualised by the notion of a visually stimulated society, in which the ease of record creation and transmission in the visual medium is contrasted with the difficulty of gaining effective subject access to the world's stores of such records. The technological developments which, in casting the visual image in electronic form, have contributed so significantly to its availability are reviewed briefly, as a prelude to the main thrust of the paper. Concentrating on still and moving pictorial forms of the visual image, the paper dwells on issues related to the subject indexing of pictorial material and discusses four models of pictorial information retrieval corresponding with permutations of the verbal and visual modes for the representation of picture content and of information need.
