Impact of the extended family on microenterprise growth in Ghana : a case study of Accra

This study examines the extended family's impact on microenterprise growth at the individual level, where microenterprise operators have some control over constraints affecting their operations. Beyond the individual level, microenterprise operators have little control over constraints such as government policies and regulations, competition from import-substitution industries and exploitation by corrupt officials. Therefore, it is at the individual level that the extended family serves as a crucial parameter of microenterprise growth and the success with which MEs graduate from the informal sector into the mainstreams of small business. Within this domain, this author has examined the extended family and found that there is a need for policy makers and MED administrators to adopt a more culturally sensitive approach to microenterprise growth if the extended family is to be engaged as a partner in their efforts to support microenterprises as a source of income and employment generation, A central question posed is why most writers on microenterprise activities in Ghana have neglected the extended family as a factor that should be considered in the design of microenterprise growth strategies and policies? The answer to this question was explored in the process of data gathering for this thesis and the results are presented here, especially in chapter 3 below. Suffice it to note here that this neglect has many roots, not least of which is the proclivity of mainstream economics, modern administration practice and the objectivity of double entry accounting based documentation procedures to focus on measurable growth in the formal sectors of the economy and structural constraints such as the lack of finance, lack of market demand, lack of access to technology and government regulations. Consequently, a noticeable trend among these writers is that they rightly advocate finance be made accessible to microenterprises, however, few question whether the finance is effectively used towards microenterprise growth. This issue is crucial in the face of evidence from this study which shows that finance accessed towards microenterprise growth is often put to other uses that negate growth thus keeping microenterprises within the bounds of the informal sector as against graduating out of the informal sector. As a result, these writers have neglected the intimate relations between the extended family and microenterprises, and most importantly, the constraint that the extended family inflicts on microenterprise growth at the individual level of activity. This study, by targeting the growth of the individual microenterprise in the socio-cultural context in which this growth must be achieved, has highlighted the constraint that the extended family does pose on MED. However, the study also shows that these constraints are important not because there is anything inherently wrong with the extended family, but because the socio-economic and policy environment is not consistent with the positive role that the extended family can and should play in the graduation of microenterprises from the informal to the formal sector of the economy in Ghana.

Chiral and achiral precursers for extended and supramolecular compounds

Organometallic compounds are building blocks for materials with applications in catalysis, pharmaceutical production and molecular sensors. Research presented in this thesis focused on the design and synthesis of compounds with supramolecular architectures. Crystal engineering these new compounds provides the basis for the next generation of advanced materials required by industry.

Gaussian vault geometry : digital design and fabrication of scaled prototypes

This paper reports on three approaches to the translation of Gaussian surface models into scaled physical prototype models. Using the geometry of Eladio Dieste's Gaussian Vaults, the paper reports on the aspects encountered in the process of digital to physical prototype fabrication. The primary focus of the paper is on exploring the design geometry, investigating methods for preparing the geometry for fabrication and constructing physical prototypes. Three different approaches in the translation from digital to physical models are investigated: rapid prototyping, two dimensional surface models in paper and structural component models using Computer Numerical Controlled (CNC) fabrication. The three approaches identify a body of knowledge in the design and prototyping of Gaussian vaults. Finally the paper discusses the digital to. fabrication translation processes with regards to the characteristics, benefits and limitations of the three approaches of prototyping the ruled surface geometry of Gaussian Vaults.

Trade-off manipulations in the development of negotiation decision support systems

Our model of negotiation for constructing Negotiation Decision Support Systems is based upon Principled Negotiation and uses trade-off manipulations in order to provide decision support. A resulting system, Family_Winner, was constructed using several information systems techniques. Trade-off Maps (a variant of Constraint Diagrams) are used to represent trade-off opportunities, while an empirically derived formula calculates the amount of compensation given to the ratings of issues remaining in dispute. The Issue Decomposition Hierarchy embedded in the system allows for the incorporation of sub-issues. Family_Winner was originally built for use in Australian Family Law. We believe our model can be extended for use in various other domains.

Family_Winner has been evaluated in the areas of industrial relations, international disputation and company disputes. Results from our evaluation suggest the system works satisfactorily in these domains. We conclude this paper by describing future projects that will develop and extend Family_Winner's functions and applicability.

The extended mind theory of cognitive distortions in sex offenders

An innovative theory of the nature of cognition, the extended mind theory (EMT), has emerged recently in the cognitive science literature. According to the EMT, the boundaries of the mind extend beyond the boundaries of skull and skin, into the world beyond. My aim in this paper is to consider the practical implications of the EMT for therapists working with sex offenders' cognitive distortions. First, I provide an overview of the key assumptions of EMT. Secondly, I draw out the major implications of this novel theory of cognition for the assessment and treatment of cognitive distortions in sex offenders. Thirdly, to make the analysis more concrete, I discuss briefly how the treatment module of cognitive restructuring could proceed according to the EMT.

Extended supervision or civil commitment for managing the risk of sexual offenders : public safety and individual rights

Since the early 1990’s, there has been a proliferation of legislative initiatives in North America, the United Kingdom, and Australasia that are intended to improve public protection from high risk sexual offenders. These laws include extended supervision of sexual offenders once released from prison and indefinite involuntary civil commitment to secure treatment facilities following the expiration of a prison sentence. The enactment of these laws has sparked intense debate and numerous legal challenges on a variety of issues, including the need to strike a proper balance between public safety and the rights of individual offenders. Recent challenges to Extended Supervision Orders in New Zealand have included the assertion that this approach is inconsistent with the Bill of Rights Act. This article compares the use of Extended Supervision Orders in New Zealand to the use of civil commitment of Sexually Violent Predators in the United States, and particularly in California, which currently confines the largest number of offenders under this type of commitment. It is argued that Extended Supervision is more flexible, less intrusive, less punitive, and less costly than civil commitment. The degree to which it is effective in improving public safety remains an empirical question.
