Abstract
Purpose
The purpose of this paper is to explore and compare the influence of diverse coarse aggregate (CA) diffusivities on reinforcing steel corrosion initiation through a quantitative modeling analysis approach.
Design/methodology/approach
Finite element analysis was used to solve two‐dimensional chloride diffusion processes, which follow the Fick's second law within the concrete cover. Two non‐dimensional time‐derating factors were employed to quantify the time‐to‐corrosion of steel rebar, Ti, for different models.
Findings
The finite diffusivity CA exhibits variable effects on Ti, depending upon: diffusivity ratio between the CA and mortar; CA type; reinforcement corrosion resistance; and cover thickness. The intent of the effects are expressed quantitatively and their implications discussed.
Originality/value
The methodology and results presented in this paper provide insights on the variable reinforcement Ti values as a function of CA diffusivity. The approach employed herein provides an effective tool to select CA materials for reinforced concrete structure where chloride‐induced corrosion is a concern.

Abstract
All seventeen had graciously agreed to my proposal to gather for a small conference to seek consensus. A generous grant from the Pierian Press Foundation would cover all of our expenses for a long weekend at a resort hotel; the only condition of the grant was that we offer our results to Reference Services Review for first publication. Over the past five years each of the seventeen had in turn accepted my challenge to answer the following question:

Abstract
Purpose – To study misbehavior as a form of dissent and resistance in an organized labor situation where traditional forms of labor unrest are suppressed and the implications for how we understand the socio-political processes through which misbehavior is constructed.
Methodology/approach – Archival research, cluster analysis, thematic analysis, critical discourse analysis, actor-network theory
Findings – Misbehavior is linked to a series of sociological practices not least of which is the production of knowledge through actor-networks and their relationship to far-reaching discourses. In the empirical material we find a conflict between discourses of labor solidarity and unfair management practices and discourses of patriotism and anticommunism.
Research limitations/implications (if applicable) – This research is based on archival data, as such it is subject to the choices of holders to contribute and archivists to collect.
Practical implications (if applicable) – This work has implications for labor leadership in the understanding of which disputes may be constrained by contextual discourses and by management in the exploration of possible means of suppressing labor unrest.
Social implications – We have found that labor unrest may be constrained by contextual discourse but that suppressed unrest may result in misbehavior and other forms of counterproductive workplace activities.
Originality/value of chapter – The relationship between contextual discourse and employee misbehavior has not been studied in depth. This work presents a new view of the struggles of the unionized workplace.

Abstract
Purpose
Through a case study of Pan American World Airways (Pan Am), this paper sets out to explore the roots of twentieth 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 paper 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 USA. Drawing on a case study of Pan Am, the paper 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 paper 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 paper contributes to an understanding of the role of language and the social construction of national identities involved in the development of international business.
