This special issue is dedicated to examining some current issues in international HRM; it contributes mainly to the field of HRM in the multinational enterprise. However, it clearly also draws on knowledge from cross-cultural IHRM. The guest editors have identified three topics that have gained tremendous importance due to the increasing globalisation of the world economy and the war for internationally qualified talent. This not only applies to multinational enterprises, but also to small and medium-sized enterprises, as senior managers are challenged to attract, retain, and motivate global talent: global assignments, global careers and global talent management. While all fields are not new and have partly been subject to prominent publications (e.g., Scullion & Collings, 2011; Cascio, 2013) new and highly relevant research questions continue to emerge and there is still a lack of empirical research in these areas.

Ontology construction for any domain is a labour intensive and complex process. Any methodology that can reduce the cost and increase efficiency has the potential to make a major impact in the life sciences. This paper describes an experiment in ontology construction from text for the animal behaviour domain. Our objective was to see how much could be done in a simple and relatively rapid manner using a corpus of journal papers. We used a sequence of pre-existing text processing steps, and here describe the different choices made to clean the input, to derive a set of terms and to structure those terms in a number of hierarchies. We describe some of the challenges, especially that of focusing the ontology appropriately given a starting point of a heterogeneous corpus. Results - Using mainly automated techniques, we were able to construct an 18055 term ontology-like structure with 73% recall of animal behaviour terms, but a precision of only 26%. We were able to clean unwanted terms from the nascent ontology using lexico-syntactic patterns that tested the validity of term inclusion within the ontology. We used the same technique to test for subsumption relationships between the remaining terms to add structure to the initially broad and shallow structure we generated. All outputs are available at http://thirlmere.aston.ac.uk/~kiffer/animalbehaviour/ webcite. Conclusion - We present a systematic method for the initial steps of ontology or structured vocabulary construction for scientific domains that requires limited human effort and can make a contribution both to ontology learning and maintenance. The method is useful both for the exploration of a scientific domain and as a stepping stone towards formally rigourous ontologies. The filtering of recognised terms from a heterogeneous corpus to focus upon those that are the topic of the ontology is identified to be one of the main challenges for research in ontology learning.

This paper describes an experiment in ontology construction from text for the Animal Behaviour domain. Our objective was to see how much could be done in a simple and rapid manner using a corpus of journal papers. We used a sequence of text processing steps, and describe the different choices made to clean the input, to derive a set of terms and to structure those terms in a hierarchy. We were able in a very short space of time to construct a 17000 term ontology with a high percentage of suitable terms. We describe some of the challenges, especially that of focusing the ontology appropriately given a starting point of a heterogeneous corpus.

To examine the detailed operation of the power distribution network in a future more electric aircraft that employs electric actuation systems, a Micro-Cap SPICE simulation is developed for one of the essential buses. Particular attention is paid to model accurately the most important effects that influence system power quality. Representative system and flight data are used to illustrate the operation of the simulation and to assess the power quality conditions within the network as the flight control surfaces are deployed. The results illustrate the importance of correct cable sizing to ensure stable operation of actuators during transient conditions.

In this study the focus is extended to purchasing and supplier relationships as companies influence their supply base by the priorities of their sourcing decision. This paper addresses sustainability in purchasing in a comprehensive way including green, social responsibility and corporate growth issues. The results of a research project which aims to reveal and structure the meaning of sustainable purchasing and the motivating forces leading companies to make efforts in purchasing for sustainability and means applied to attain achievements at some fields of sustainability. After presenting the results of literature review, some theory development was done to create a framework in which it is possible to describe the sustainability means applied and the motivating force behind. This framework serves as a basis of an empirical investigation among Hungarian companies. The empirical results validated the theoretical framework: the number and the characteristics of sustainability activities were determined by the type of motivation (to avoid negative effects, compliance to expectations, to attain positive effects). Our research project was part of the research project In Global Competition.
