Multilabel classification using error correction codes

This paper presents a multilabel classification method that employs an error correction code together with a base ensemble learner to deal with multilabel data. It explores two different error correction codes: convolutional code and BCH code. A random forest learner is used as its based learner. The performance of the proposed method is evaluated experimentally. The popular multilabel yeast dataset is used for benchmarking. The results are compared against those of several exiting approaches. The proposed method performs well against its counterparts.

Key predistribution scheme using finite fields and reed muller codes

Resource constraint sensors of a Wireless Sensor Network (WSN) cannot afford the use of costly encryption techniques like public key while dealing with sensitive data. So symmetric key encryption techniques are preferred where it is essential to have the same cryptographic key between communicating parties. To this end, keys are preloaded into the nodes before deployment and are to be established once they get deployed in the target area. This entire process is called key predistribution. In this paper we propose one such scheme using unique factorization of polynomials over Finite Fields. To the best of our knowledge such an elegant use of Algebra is being done for the first time in WSN literature. The best part of the scheme is large number of node support with very small and uniform key ring per node. However the resiliency is not good. For this reason we use a special technique based on Reed Muller codes proposed recently by Sarkar, Saha and Chowdhury in 2010. The combined scheme has good resiliency with huge node support using very less keys per node.

Use of moral theory to analyse the ethical codes of built environment professional organisations: A case study of the Royal Institution of Chartered Surveyors

Purpose – The purpose of this paper is to discuss the use of moral theory as a philosophical analytical framework for built environment organisations' ethical codes of practice. The identified moral theories under consideration are “deontology”, “consequentialism” and “virtue ethics”.

Design/methodology/approach – The paper uses a case study to examine the use of moral theory to explain the ethical codes of practice of built environment professional organisations. The chosen organisation is the Royal Institution of Chartered Surveyors (RICS). The approach for conducting the case study is through semi-structured interviews with experienced RICS members which gather views on the application of moral theory to explain the RICS ethical principles.

Findings – The case study revealed that there are mixed views on the use of moral theory to explain the RICS code of practice. The general view is that deontology is the most suitable theory to explain the fact that the work or process has been undertaken correctly. On the other hand, there is also a view amongst senior professionals that virtue ethics is most appropriate as it addresses the importance of both the correct “result” and the correct “process”.

Research limitations/implications – The paper uses a case study approach to examine the ethical code of one built environment professional organisation. This research does not therefore claim empirical generalisation but instead provides illustrations on the use of moral theory to explain the code of practice of a built environment professional organisation. The paper is based on a series of interviews. The findings should be understood as the aggregated opinions of the interviewees.

Originality/value – The paper makes an original contribution to existing literature on the theoretical analysis of codes of practice for built environment professional organisations. It describes research which is the first to use moral theory as a framework for analysing rules of conduct of built environment professional organisations.

Distribution grid codes : opportunities and challenges

Traditional distribution networks were not originally designed to accommodate power generation facilities. The installation of distributed generation (DG) units with significatn capacity in these passive networks can cause reverse power flows which will result in some conflicts with the operation of the existing protection system. In this context, utilities around the world have started establishing requirements to ensure safe and reliable interconnection of generators in low- and medium-voltage networks. Grid interconnection is presently one of the most important issues involving DG. This paper presents a critical review of the requirements adopted by distribution companies in selected countries such as the USA, the UK, germany and Australia to facilitate the connection of DG. Critical issues such as voltage regulation, islanding operation, dynamic interactions among DG and loads are discussed to identify a few points where attention is still needed to improve the reliability of distribution systems

A cross-cultural construct of the ethos of the corporate codes of ethics: Australia, Canada and Sweden

The objective of this paper is to develop and describe a construct of the ethos of the corporate codes of ethics (i.e. an ECCE construct) across three countries, namely Australia, Canada and Sweden. The introduced construct is rather unique as it is based on a cross-cultural sample seldom seen in the literature. While the outcome of statistical analyses indicated a satisfactory factor solution and acceptable estimates of reliability measures, some research limitations have been stressed. They provide a foundation for further research in the field and testing of the ECCE construct in other cultural and corporate settings. We believe that the ECCE construct makes a contribution to theory and practice in the field as it outlines a theoretical construct for the benefit of other researchers. It is also of managerial interest as it provides a grounded framework of areas to be considered in the implementation in organizations of corporate codes of ethics.

A cross cultural comparison of the contents of codes of ethics: USA, Canada and Australia

This paper examines the contents of the codes of ethics of 83 of the top 500 companies operating in the private sector in Australia in an attempt to discover whether there are national characteristics that differentiate the codes used by companies operating in Australia from codes used by companies operating in the American and Canadian systems. The studies that were used as a comparison were Mathews (1987) for the United States of America and Lefebvre and Singh (1992) for Canada. The major conclusion is that, whilst Australian codes do have some characteristics that differentiate them from the other two groups, it appears that companies in all three cultures are driven by the same motives to develop codes.

Migration intermediaries and codes of conduct: temporary migrant workers in Australian horticulture

Over recent decades, developments in network governance have seen governments around the world cede considerable authority and responsibility to commercial migration intermediaries for recruiting and managing temporary migrant labour. Correspondingly, a by-product of network governance has been the emergence of soft employment regulation in which voluntary codes of conduct supplement hard (enforceable) legal employment standards. This paper explores these developments in the context of temporary migrant workers employed in Australian horticulture. First the paper analyses the growing use of temporary migrant labour in this industry. It then describes how different types of intermediaries interact with this workforce. The paper then outlines both hard and soft employment regulations, and contrasts them with actual employment conditions, questioning how a network governance approach has affected this vulnerable workforce. The paper concludes that changes in network governance of migration and employment relations have emasculated formal legal regulation, leaving market forces to operate without effective or ethical constraints at the expense of the public good.
