Digital system bus integrity

This report summarizes and describes the results of a study of current or emerging multiplex data buses as applicable to digital flight systems, particularly with regard to civil aircraft. Technology for pre-1995 and post-1995 timeframes has been delineated and critiqued relative to the requirements envisioned for those periods. The primary emphasis has been an assured airworthiness of the more prevalent type buses, with attention to attributes such as fault tolerance, environmental susceptibility, and problems under continuing investigation. Additionally, the capacity to certify systems relying on such buses has been addressed

Assessment of avionics technology in European aerospace organizations

This report provides a summary of the observations and recommendations made by a technical panel formed by the National Aeronautics and Space Administration (NASA). The panel, comprising prominent experts in the avionics field, was tasked to visit various organizations in Europe to assess the level of technology planned for use in manufactured civil avionics in the future. The primary purpose of the study was to assess avionics systems planned for implementation or already employed on civil aircraft and to evaluate future research, development, and engineering (RD&E) programs, address avionic systems and aircraft programs. The ultimate goal is to ensure that the technology addressed by NASa programs is commensurate with the needs of the aerospace industry at an international level. The panel focused on specific technologies, including guidance and control systems, advanced cockpit displays, sensors and data networks, and fly-by-wire/fly-by-light systems. However, discussions the panel had with the European organizations were not limited to these topics

Managing in an economic crisis: The role of market orientation in an international law firm

This research paper contributes to the understanding of the relationship between market orientation and performance in the context of a law firm during a time of economic crisis. The contribution is twofold, adding to the fairly limited research on market orientation within law firms, and to the limited research on the role of market orientation in times of economic crisis. The findings, from the questionnaire survey and semi-structured interviews within practice groups of a large multinational law firm, conclude that market orientation is important during an economic crisis. Those practice groups with higher market orientation scores withstand the increased turbulence and outperform those practice groups with lower market orientation scores

An exploratory study of international opportunity identification among family firms

This research examines how family firms identify international opportunities. Family firms are characterised by long-term orientation, being risk averse, and benefiting from familiness capital, resources and capabilities related to family involvement and interactions. Built upon opportunity identification theory and in two perspectives of accidental discovery and purposeful search, we explore the role of social and business networks, and prior knowledge in a first and subsequent international opportunity identification by family firms. In addition, we attempt to understand the role of family characteristics in the process of opportunity identification. Multiple case studies were carried out with seven family businesses from emerging economies, namely, India, Turkey and Taiwan. The findings of this research illustrate that because of being risk averse and long-term oriented, family firms are more likely to identify the first international opportunity through accidental discovery and subsequent international opportunities through purposeful search. The findings of this research show that, as risk-averse firms, family firms are not proactive in initiating international opportunity identification but rather learn about opportunities through accidental discovery. After the first experience of internationalisation, family firms engage in a more purposeful search to identify avenues that will aid their longevity through internationalisation. In the identification of firms' first international opportunities, it is mainly social networks that play a crucial role, especially those that contain international industry and market-specific knowledge. There is also a positive relationship between a family entrepreneur's prior knowledge and international opportunity identification and this relationship is moderated by the prior knowledge of their network. Familiness capital of these organisations can also play a role in long-term international opportunity identification

Integration of Non-market and Market Activities in Cross-border Mergers and Acquisitions

Drawing on the resource dependence theory and the resource-based view, this paper investigates the interactions between market and nonmarket activities of firms in the context of the post-merger integration phase in cross-border mergers and acquisitions (M&As). Based on a cross-country survey of 111 M&A practitioners who were personally involved in cross-border M&As around the world, we test seven hypotheses on various market and nonmarket aspects of post-merger integration. We find a positive correlation between buffering strategies and adaptive capabilities in the nonmarket environment, and between bridging and adaptive capabilities in the market environment. However, we could not find any significant correlation between buffering and adaptive capabilities in the market environment, and bridging and adaptive capabilities in the nonmarket environment. We also find that adaptability in the nonmarket environment is positively correlated with adaptability in the market environment, and in turn adaptability in the market environment leads to positive organizational performance of a cross border M&A. These results provide further support for the value of the alignment between market and nonmarket activities and help to fill a gap in the literature on the market-nonmarket interactions in post-merger integration

Spillovers through backward linkages and the export performance of business services. Evidence from a sample of Italian firms

We provide evidence on the role of spillovers through vertical linkages in service firms' internationalisation process. We combine input-output coefficients with region-level information on downstream manufacturing sector exports to build a measure of spillovers through backward linkages, which we assess as a systematic determinant of Italian BS firms' export status. Once considered firm and sector specificities, export spillovers especially matter for exporting to high-income economies outside Europe. This finding originates from higher sunk costs stemming from greater distance to the destination market and tougher competition within the destination market. Furthermore, the spillovers' geographical scope is mainly local. We thus contribute to international business theory by generalising existing evidence from case studies on the importance of buyer-supplier relationships for service firms' internationalisation across several BS sectors. Our research carries important implications for international business practices as well, as joining networks with internationalised customers may play an important role in enhancing BS firms' exports, regardless of the BS supplied. © 2013 Elsevier Ltd

The COSMOS-UK User Guide is a comprehensive guide to the data collected by COSMOS-UK, including the near-real time soil moisture data derived from counts of netrons derived from cosmic rays. The User Guide contains: i) information about the sites, their locations and other meta data. ii) Details of the instruments deployed at each site. iii) Background information about the cosmic ray neutron counter which is used to derive soil moisture within a 12 hectare footprint. iv) Descriptions of data and information products that are available from COSMOS-UK

The disruption of proteostasis in neurodegenerative diseases

Cells count on surveillance systems to monitor and protect the cellular proteome which, besides being highly heterogeneous, is constantly being challenged by intrinsic and environmental factors. In this context, the proteostasis network (PN) is essential to achieve a stable and functional proteome. Disruption of the PN is associated with aging and can lead to and/or potentiate the occurrence of many neurodegenerative diseases (ND). This not only emphasizes the importance of the PN in health span and aging but also how its modulation can be a potential target for intervention and treatment of human diseases.info:eu-repo/semantics/publishedVersio
