Interdependent supply relationships as institutions: The role of HR practices

This paper aims to use institutional theory to explore the role of human resource (HR) practices as carriers in the evolution of interdependent supply relationships. Design/methodology/approach – This is a qualitative study of an inter-firm supply relationship where the two partners were interdependent as a result of a “closed loop” supply relationship. The paper explores the perspectives of employees at multiple levels within both partners, and collects pluralist evidence from 36 interviewees from both sides of the dyad. It collects documentary evidence such as minutes, contractual agreements and HR documents. This paper re-analyses the evidence from earlier work using an institutional theory framework. Findings – Using Scott's “three pillars” the paper shows that HR practices can act as carriers of regulative, normative and cultural-cognitive elements in interdependent supply relationships through both formal and informal mechanisms. Regulative elements were less evident, but could be fundamental in shaping the other two. A tension was found between institutional pressures at the inter- and intra-firm levels, an emergence of innovative practices and new routines at inter-organizational level, and an evolution over time that could involve a de-institutionalisation of the relationship as a result of internal priorities competing with the resource requirements of the supply relationship. Originality/value – The paper addresses the interface between OM and organisational theory. Areas are proposed where institutionalisation of a supply relationship can be strengthened or weakened. The findings further challenge the view of supply relationships as a “spectrum” in which progress is unidir

The Integration of Multiple and Diverse Knowledge Representation Paradigms using a Blackboard Architecture

There is increasing evidence that designers of future real-time embedded systems are turning to knowledge-based techniques in order to solve complex problems where algorithmic techniques have failed to produce a solution. In addition, many applications have been mandated to use the Ada programming language for all implementation software, including the knowledge-based components. This thesis identifies three essential requirements needed to support the construction of these systems: first, the need to provide a library of Ada knowledge-based components that supports a variety of knowledge representation paradigms to model the diverse expert domains being encountered in complex applications; second, the need to provide the user with the means of creating and controlling multiple independent instances of the knowledge-based components to cope with the complexity and scale of the implementations; and third, the need to provide an integrating architecture in which the knowledge-based components may be embedded directly into an application environment. These requirements have been satisfied by using ideas derived from the concept of abstract data types to construct a library of knowledge-based components; the components have been called abstract knowledge types. Subsequently, multiple instances of the abstract knowledge types have been integrated in modules called knowledge sources, which model specific problem knowledge domains. The knowledge sources have been used to construct a blackboard architecture. The abstract knowledge types have been used to build a prototype university timetabling system in order to demonstrate their use. The research has shown that the abstract knowledge type integration approach results in a uniform implementation strategy for both conventional and knowledge-based components

Communication Strategies as a Basis for Crisis Management Including Use of the Internet as a Delivery Platform

ABSTRACT Eighty per cent of small companies without a comprehensive crisis plan vanish within two years of suffering a major disaster—a remarkable and ominous statistic. Crises are occurring more often in all organizations, and when they occur, they are leaving a wake of financial, operational, and reputational damage. Why this trend, now? There are five important reasons: 1) a more volatile workplace involving financial, legal, or management issues within the organization; 2) an extreme production mentality often obscuring the conditions under which crises might otherwise be recognized, addressed, or mitigated; 3) enhanced technological platforms for information delivery, such as the Internet, generating a revolving information door thus promoting organizational stress and crisis; 4) fast-paced and invasive journalism practices that eliminate invisibility for decisionmaking or reaction; and, 5) lack of strategic planning for crisis. There is an increasing body of evidence suggesting that crises in an organizational environment, whether created by act-of-God or manmade circumstances, have defined and predictable characteristics often relating to communication problems in the discourse community. It is also evident that solutions exist to reduce the incidence and the intensity of crisis within this discourse community. Approaches include organizational vulnerability assessments, messaging strategies, forensic media tactics, and dedicated efforts to build relationships with important stakeholders. Each of these has as its foundation a vigorous strategic communication plan. Crisis plans are necessary in today’s business environment, and effective communication is an essential element of any crisis plan. This dissertation will focus on communication methodology as a means of crisis avoidance and crisis mitigation

Development of an ontology for aerospace engine components degradation in service

This paper presents the development of an ontology for component service degradation. In this paper, degradation mechanisms in gas turbine metallic components are used for a case study to explain how a taxonomy within an ontology can be validated. The validation method used in this paper uses an iterative process and sanity checks. Data extracted from on-demand textual information are filtered and grouped into classes of degradation mechanisms. Various concepts are systematically and hierarchically arranged for use in the service maintenance ontology. The allocation of the mechanisms to the AS-IS ontology presents a robust data collection hub. Data integrity is guaranteed when the TO-BE ontology is introduced to analyse processes relative to various failure events. The initial evaluation reveals improvement in the performance of the TO-BE domain ontology based on iterations and updates with recognised mechanisms. The information extracted and collected is required to improve service k nowledge and performance feedback which are important for service engineers. Existing research areas such as natural language processing, knowledge management, and information extraction were also examined

Ideas, philosophy and personality in the history of Kwazulu-Natal’s Town and Regional Planning Commission

1997 is likely to mark the end of an era for planning in KwaZulu-Natal. The provincial government is hoping to put in place legislation by the end of this year which would replace the forty-five year old Town and Regional Planning Commission with a new Planning and Development Commission. For the existing Commission it is a time of introspection: what contribution did the existence of the Commission make to planning and development in KwaZulu-Natal between 1951 and 1996? What kind of difference did the Commission make? How can its contribution be explained? Such questions give rise not to meaningless reminiscence, but speak directly to the present. The first piece of post-apartheid planning legislation, the Development Facilitation Act of 1995, provides for planning commissions in both provincial and national spheres of government, and there is serious debate as to the potential roles which such commissions might play. Deconstruction of the historical practice of planning can play an important role in informing current debates

DNA Methylation: A Timeline of Methods and Applications

DNA methylation is a biochemical process where a DNA base, usually cytosine, is enzymatically methylated at the 5-carbon position. An epigenetic modification associated with gene regulation, DNA methylation is of paramount importance to biological health and disease. Recently, the quest to unravel the Human Epigenome commenced, calling for a modernization of previous DNA methylation profiling techniques. Here, we describe the major developments in the methodologies used over the past three decades to examine the elusive epigenome (or methylome). The earliest techniques were based on the separation of methylated and unmethylated cytosines via chromatography. The following years would see molecular techniques being employed to indirectly examine DNA methylation levels at both a genome-wide and locus-specific context, notably immunoprecipitation via anti-5′methylcytosine and selective digestion with methylation-sensitive restriction endonucleases. With the advent of sodium bisulfite treatment of DNA, a deamination reaction that converts cytosine to uracil only when unmethylated, the epigenetic modification can now be identified in the same manner as a DNA base-pair change. More recently, these three techniques have been applied to more technically advanced systems such as DNA microarrays and next-generation sequencing platforms, bringing us closer to unveiling a complete human epigenetic profile
