This paper presents the results of a heading estimation method for a remotely operated vehicle (ROV). The output rate of commercially available underwater compasses is typically in the order of a few Hz. Heading frequencies of at least 1 KHz are desirable for navigation and control purposes.

The estimation was performed by fusioning the signals of three inertial sensors: the ROV’s own underwater compass (which operates roughly at 10 Hz or less), the ROV’s embedded gyro and an additional angular rate sensor that provides readings from 1 to 3 KHz. The output signal of the additional angular rate sensor is not part of the proposed Kalman filter. Nonetheless a five-point Newton-Cotes closed integration of such signal is fed into the Kalman filter implementation that performs the required heading estimation at 1 KHz or more.

The proposed Kalman filter implementation is a suitable approach to estimate heading position even though the original compass signal rate is significantly slower than the signal required for both assisted and autonomous control.

The estimated heading yield good results in both simulation and experimental environments.

The method was embedded in a dedicated 16-bit DSP that handles both the acquisition of the three signals and the heading estimation, hence resulting in a very low-cost solution. The embedded solution was tested in the developed submarine and the obtained high-rate heading parameter is now used by the control system of the ROV.

The purpose of this study is to understand the moderating role of market dynamism in the relationship between organizational flexibility and pioneering behavior in tourism firms in Arequipa, Peru. This study aims to delve into the antecedents of pioneering orientation understood as a strategic stance that favors the creation and launch of new products in the market.

This empirical study involved the analysis, using partial least squares regression, of 306 surveys administered to mangers of tourism enterprises. Mediation has also been examined using the bootstrapping method.

The results show that organizational flexibility has a positive impact on pioneering behavior, while market dynamism positively mediates this relationship.

This work provides interesting theoretical and empirical contributions for the management of firms in the tourism sector. Firms should develop capabilities to reconfigure their processes and products to adequately implement and exploit innovations generated in their organizations. In addition, tourism enterprises should improve their performance by creating new products and/or services, aligned with changes in customers' purchasing and consumption habits.

This study aims to elaborate on the background of pioneering orientation understood as a strategic stance that favors the creation and launch of new products in the market. This study also proposes that market dynamism is a factor to be considered in improving this relationship.

The purpose of this research is to examine the effect of industry clockspeed on the relationship between supply chain management (SCM) practices, from both upstream and downstream sides of the supply chain, and SCM performance.

The study is based on a questionnaire sent to manufacturing companies in the Republic of Ireland. The relationships between the constructs are analysed through regression analysis.

The results suggest that the relationship between SCM practices and SCM performance is not monotonic across varying levels of industry clockspeed. Although mixed support was found for the hypothesized relationships, this research contributes considerably to the theoretical development of the contingency view in the SCM literature.

Managers should be aware that the rate of change in their industries can affect the way SCM practices across the supply chain impact on SCM performance.

The literature review has shown that empirical studies which address the relationship between SCM practices and SCM performance provide mixed results. One possible explanation lies in the contingency theory. This paper contributes to the theoretical development of the contingency view in the SCM literature by showing that industry clockspeed affects the way SCM practices impact on SCM performance.

The purpose of this research is to examine the effect of internal lean practices on multiple operational performance dimensions, and assess the contingency perspective of these relationships with respect to industry clockspeed.

The study is based on empirical data gathered from 228 manufacturing companies in the Republic of Ireland. The relationships between the constructs are analyzed through regression analysis.

The results indicate that the relationships between internal lean practices and quality, delivery, flexibility and cost were found to be positive and significant. Further, industry clockspeed was found to moderate the relationship between internal lean practices and quality, delivery and flexibility, but not cost.

While internal lean practices can improve operational performance, managers should be aware that internal lean practices are not universally applicable, and the rate of change within an industry should be considered at the time of implementing lean principles.

Much of the lean literature tends to be biased towards its effectiveness. However, empirical evidence shows that not all lean implementation have led to positive results, which has been attributed to the general complexity in the relationship between internal lean practices and performance. We propose to investigate further this relationship by disaggregating operational performance into four of its dimensions, namely quality, delivery, flexibility and cost, and by investigating the possible contingency effect of industry clockspeed.

This paper seeks to report the results of an empirical study examining the value creation process of e‐business (EB) applications from a supply chain perspective.

A questionnaire was sent to procurement managers located in the German automotive supply chain. Interaction effects were examined through regression analyses to illustrate the moderating role of the suppliers' EB readiness in the value creation process throughout the supply chain.

Based on the resource‐based view (RBV) and previous research this study illustrates that EB applications (i.e. EB interaction applications, EB coordination applications and EB integration applications) have a significantly stronger positive impact on operational performance when a company's key suppliers are ready and willing to engage in EB (suppliers' EB readiness).

Although research on the performance impact and business value of EB applications has advanced over the past years, there is still a scarcity of research taking a supply chain perspective on EB value. This study addresses this gap through reporting results of an empirical study examining the value creation of EB applications through the moderating role of suppliers' EB readiness on the EB applications‐operational performance relationship throughout the supply chain. This paper will thus be beneficial for supply chain managers considering investing in EB systems and will support further research in EB value creation in supply chains.

The purpose of this paper is to extend previous green supply chain management (GSCM) research by developing and empirically testing a conceptual framework that investigates the relationships between three dimensions of integrated green supply chain management (iGSCM) and multiple dimensions of operational performance.

The study is based on survey data collected from 126 automotive manufacturers in China. The relationships between theoretical constructs are analysed using structural equation modelling.

This study generates important findings of the significant and positive relationships between iGSCM (internal GSCM, GSCM with customers and GSCM with suppliers) and operational performance in terms of flexibility, delivery, quality and cost.

It is important for managers to simultaneously consider internal GSCM and GSCM with customers and suppliers when implementing environmental sustainability in the supply chains. Overlooking either internal GSCM or external GSCM may hinder their efforts to improve operational performance.

This study contributes to the literature by defining iGSCM that combines three main dimensions, namely, internal GSCM, GSCM with customers and GSCM with suppliers, and empirically testing its impact on multiple operational performance dimensions.

Destination management is in urgent need of analytical and policy tools, and even more so in the context of tourism for development programs. Understanding both structural elements and dynamic processes are essential. This chapter describes a model of destinations which considers three types of structural components: factors/resources, attractors (of tourism demand), and support systems. It analyzes as well the optimizing behavior of destination stakeholders, both endogenous and exogenous, as a way to understand destination dynamics. The model can be applied in the strategic positioning of destinations as well as in achieving competitiveness and sustainability—ultimately contributing to development—through tourism policy plans and governance processes. The model was born in the context of a European Eureka–ComTur research project, and has been tested in a variety of destinations.

The national immigrant rights campaign of 2006 stands as one of the largest mobilizations by people of color in US history, yet less scholarly attention has been given to systematically comparing these mobilizations at the local level. To develop an understanding of what led to sustained mobilization, a comparative case study analysis of seven cities in California's San Joaquin Valley is employed. The empirical evidence is based on interviews with key organizers and participants, newspaper documentation of protest events, census data, and other secondary sources. I find that the presence and size of policy threats explained the initial protest during the spring of 2006 in all localities, but cities with elaborate resource infrastructures (preexisting organizations, histories of community organizing, and coalitions) had more enduring levels of collective action.
