Abstract
Purpose
The paper aims to develop the survey utilized in this research as a data collection tool for the study of organizational responsiveness.
Design/methodology/approach
Drawing from the operations and strategic management literature, measurement scales were developed in order to empirically test five proposed enablers of organizational responsiveness: environmental scanning, strategic planning, flexible manufacturing infrastructures, supply chain governance mechanisms, and multi‐skilled workers.
Findings
The survey produced a total of 66 responses from 59 companies in three industries: automotive suppliers, instrumentation equipment, and semiconductor components. Three of the five enablers were found to be bi‐dimensional, which produced a survey instrument with eight separate measurement scales. Coefficient alpha was observed to be within the acceptable range for all construct scales and factor analysis confirmed unidimensionality for each construct.
Research limitations/implications
The survey instrument presented in this paper provides a better understanding of the processes that enable organizational responsiveness. This measurement scale will serve as a tool that will allow future researchers to more accurately operationalize the enablers of organizational responsiveness.
Practical implications
The ability of firms to quickly respond to changes in their external environment is a primary determinant of firm performance. This research provides important practical implications for firms wishing to maximize their levels of agility and flexibility in responding to changing environmental conditions.
Originality/value
Few measurement scales currently exist that can be utilized to measure and predict rates of organizational responsiveness. The survey instrument developed as part of this research provides important insights into various organizational factors that enable organizational responsiveness.

Abstract
Presents a simulation model of the “Contract change process” for an aerospace manufacturing firm. The model was developed to simulate the activities from the time when a customer’s request is received to the two points in time where a preliminary schedule and a formal proposal is returned to the customer. The model was developed in a two‐stage approach. First, the process was studied and documented in US Air Force integrated computer aided manufacturing definition language for function modeling an IDEF0 model which defined the relationships between each pair of activities. Second, using the structural information provided by the IDEFo model, a simulation model using simulation language for alternative modeling (SLAMII) was developed. Data were obtained from archival sources in the department’s database. The data were analyzed according to the quarter in which they were received. From this, arrival time data distributions were estimated for each of the four quarters to capture the seasonality element in the company’s business. Next, the data were separated into three levels of difficulty to define complex, routine and simple tasks. From this, three distributions of activity times were developed for each set of tasks. The results will allow for the study of reengineering and downsizing decisions for the contract change process in the aerospace industry, under conditions of seasonal and task complexity variations.

Abstract
Buyer‐supplier relationships play an important role in an organization’s ability to respond to dynamic and unpredictable change. If the relationship is too restrictive, flexibility will be difficult to achieve and, if it is too lenient the risk of opportunism will be present. This paper provides a framework for understanding how buyer‐supplier relationships have evolved over the past two decades from transaction processes based on arms‐length agreements to collaborative processes based on trust and information sharing. To achieve this objective, buyer‐supplier relationships are reviewed from the perspectives of transaction cost theory, strategy‐structure theory and resource‐based theory of the firm. Findings from early supply chain research are contrasted with the findings of more current research to provide a better understanding of how these relationships have changed. Current theory is extended by offering two proposals that test the influence of trust and information sharing and a third proposal that rejects the notion that supply chain alliances lead to monopolistic practices.

Abstract
Purpose
This paper aims to present the impact analysis of payload rendezvous with tethered satellite system and the design of an adaptive sliding mode controller which can deal with mass parameter uncertainty of targeted payload, so that the proposed cislunar transportation scheme with spinning tether system could be extended to a wider and more practical range.
Design/methodology/approach
In this work, dynamical model is first derived based on Langrangian equations to describe the motion of a spinning tether system in an arbitrary Keplerian orbit, which takes the mass of spacecraft, tether and payload into account. Orbital design and optimal open-loop control for the payload tossed by the spinning tether system are then presented. The real payload rendezvous impact around docking point is also analyzed. Based on reference acceleration trajectory given by optimal theories, a sliding mode controller with saturation functions is designed in the close-loop control of payload tossing stage under initial disturbance caused by actual rendezvous error. To alleviate the influence of inaccurate/unknown payload mass parameters, the adaptive law is designed and integrated into sliding mode controller. Finally, the performance of the proposed controller is evaluated using simulations. Simulation results validate that proposed controller is found effective in driving the spinning tether system to carry payload into desired cislunar transfer orbit and in dealing with payload mass parameter uncertainty in a relatively large range.
Findings
The results show that unideal rendezvous manoeuvres have significant impact on in-plane motion of spinning tether system, and the proposed adaptive sliding mode controller with saturation functions not only guarantees the stability but also provides good performance and robustness against the parameter and unstructured uncertainties.
Originality/value
This work addresses the analysis of actual impact on spinning tether system motion when payload is docking with system within tolerated docking window, rather than at the particular ideal docking point, and the robust tracking control of deep-space payload tossing missions with the spinning tether system using the adaptive sliding mode controller dealing with parameter uncertainties. This combination has not been proposed before for tracking control of multivariable spinning tether systems.

Abstract
Purpose
This paper aims to contribute to the project of recognising the contribution of female scholars to the development of marketing thought. The paper presents a biography of Elizabeth Ellis Hoyt, a home economist, who contributed to the shaping of contemporary ideas about consumption and the consumer.
Design/methodology/approach
Source material used includes the Elizabeth Ellis Hoyt Papers (1884‐2009) in the Iowa State University Archives. The collection contains a variety of materials, of which the most important for this paper were news clippings, personal diaries (1907‐1918), and published and unpublished manuscripts (1953, 1964, n.d.). Also important for this study were two sources published by Alison Comish Thorne, Elizabeth Hoyt's PhD student. These include Thorne's autobiography Leave the Dishes in the Sink and her entry on Elizabeth Hoyt in the Biographical Dictionary of Women Economists.
Findings
The paper documents Elizabeth Hoyt's development of marketing thought, focusing on her early work on the cost of living index and subsequent contributions to an expanded theory of consumption and consumer learning.
Originality/value
Elizabeth Hoyt is one of a group of female home economists who pioneered consumption economics in America in the 1920s and 1930s yet who have been neglected in published accounts. Notwithstanding a short biographical note in the Biographical Dictionary of Women Economists, Hoyt's life and work are not yet documented.

Abstract
Our study explores friction costs in terms of competition and market structure, considering factors such as market share, industry leverage levels, industry hedging levels, number of peers, and the geographic concentration that influences reinsurance purchase in the Property and Casualty insurance industry in China. Financial factors that influence the hedging level are also included. The data are hand collected from 2008 to 2015 from the Chinese Insurance Yearbook. Using panel data analysis techniques, the results are interesting. The capital structure shows a significant negative relationship with the hedging level. Group has a negative relationship with reinsurance purchases. Assets exhibit a negative relationship with hedging levels. The hedging level has a negative relation with the individual hedging level. Insurers have less incentive to hedge because it provides less resource than leverage. The study also robustly investigates the strategic risk management separately by the financial crises.

Abstract
Purpose
Amid widespread social and cultural shifts and advocacy toward lesbian, gay, bisexual, and transgender (LGBT) rights remain a hidden population of homeless adolescents who are cast out from families and communities because of their sexual and gender orientation. The result is an over-representation of LGBT adolescents among the homeless in the United States. The purpose of this paper is to provide a review of literature and research which explores the status and needs of LGBT homeless adolescents in the United States.
Methodology/approach
To understand the experiences of LGBT adolescents leading up to and during homelessness, I provide a thematic and critical review of four decades of research to connect our understanding of the LGBT homeless experience with institutional and collective efforts that work to promote their well-being.
Findings
Bringing together this body of literature, I explore four interrelated questions. First, has the rate of homelessness increased for LGBT adolescents in recent decades? Second, what is the experience of LGBT adolescents who become homeless? Third, what role does advocacy and support play in ameliorating the difficulties these young people face? Finally, what role can future research and policy play in shaping the well-being of LGBT adolescents who become homeless?
Research limitations/implications
Understanding the experience of homeless LGBT adolescents and the collective advocacy efforts designed to promote their well-being offers insight into the intersection of symbolic, inter-personal, and institutional forces which shape their trajectories.
