An exploration of embeddedness : with special reference to Japan : a thesis presented in partial fulfilment of the requirements for the degree of Master of Arts in Economics at Massey University
This thesis utilises the economic sociology concept of embeddedness as the theoretical underpinning to provide an alternative perspective to traditional explanations of economic growth. In general, the advantages of social embeddedness have been the main focus in the literature on the topic. The main purpose of this study is to explore, with special reference to Japan, how embedded relationships could both enable and hinder growth. The study examines the operation of embedded ties in four key areas: inter-firm interaction with an emphasis on the auto-industry; embedded relationships within the financial sector; networks in the internationalisation of firms and embeddedness between government and business, including a case study of the construction industry. It finds that while embedded ties have several advantageous facets, they also have the potential to be an impediment to growth, flexibility and adaptability to change. Network ties can expand and become so rigidly structured, especially in a Confucian society like Japan, as to become obstacles particularly in the face of changing economic circumstances. They can atrophy. This finding led to the development of the concluding notion of "atrophied embeddedness"

Emission of reactive oxygen species during degradation of iron gall ink
Iron gall inks are characterised by high contents of acids and transition metals, promoting degradation of cellulose due to hydrolysis and oxidation, respectively. Their chemical interaction with the environment is not well understood, especially in view of emissions of degradation products which could lead to spread of degradation processes.
In order to study the emissions, we employed gas chromatography/mass spectrometry following headspace micro-extraction, and liquid chromatography following hydroxyl radical scavenging with appropriate probes. We also studied chemiluminescence of cellulose affected by ink degradation.
We show that while the emissions of organic volatile degradation compounds by inks are less intense than those of surrounding paper, ink does promote the degradation of cellulose across big distances (from object to object). We were able to link this to emission of reactive oxygen species, probably hydrogen peroxide. Its emission from ink is considerably more intensive than from paper
Complex maps without invariant densities
We consider complex polynomials for and
, and find some combinatorial types and values of such that
there is no invariant probability measure equivalent to conformal measure on
the Julia set. This holds for particular Fibonacci-like and Feigenbaum
combinatorial types when sufficiently large and also for a class of
`long-branched' maps of any critical order.Comment: Typos corrected, minor changes, principally to Section
A Review of Indigenous Food Crops in Africa and the Implications for more Sustainable and Healthy Food Systems
Indigenous and traditional foods crops (ITFCs) have multiple uses within society, and most notably have an important role to play in the attempt to diversify the food in order to enhance food and nutrition security. However, research suggests that the benefits and value of indigenous foods within the South African and the African context have not been fully understood and synthesized. Their potential value to the African food system could be enhanced if their benefits were explored more comprehensively. This synthesis presents a literature review relating to underutilized indigenous crop species and foods in Africa. It organizes the findings into four main contributions, nutritional, environmental, economic, and social-cultural, in line with key themes of a sustainable food system framework. It also goes on to unpack the benefits and challenges associated with ITFCs under these themes. A major obstacle is that people are not valuing indigenous foods and the potential benefit that can be derived from using them is thus neglected. Furthermore, knowledge is being lost from one generation to the next, with potentially dire implications for long-term sustainable food security. The results show the need to recognize and enable indigenous foods as a key resource in ensuring healthy food systems in the African continent
Using the Delphi Technique to Identify BPM Capability Areas
Organizations increasingly recognize the need to adopt a process orientation as a means of approaching challenges such as globalization, Enterprise Systems implementations or alternative improvement perspectives. A comprehensive understanding of the operational capacity to support and extend BPM strategies is critical to this endeavour. To this end, organizations require appropriate frameworks, which assist in identifying and evaluating their BPM capabilities. The development of maturity models has long been recognized as a means of assessing capabilities within a given domain. However, due to the idiosyncratic structure of many of the more than 150 available maturity models they can not be translated into tools that are embraced and applied by practitioners. To address this issue, the Delphi technique has been adopted during the development of a maturity model for Business Process Management. This paper presents the design and conduct of the Delphi Study series including the major outcomes being definitions of the six factors critical to BPM (i.e. Strategic Alignment, Governance, Methods, Information Technology, People and Culture) and the identification of capability areas whose measurement is seen to be necessary for assessing the maturity of these factors
