Institutional Quality and Trade in Pacific Island Countries
No full textThis research examines the impact of institutional quality on trade in selected Pacific Island Countries (PICs). Four indicators of institutional quality are chosen: government effectiveness, rule of law, regulatory quality and control of corruption; for six PICs: Fiji, Kiribati, Samoa, Solomon Islands, Tonga and Vanuatu.Institutional Quality on Trade

The role of households in solid waste management in East African capital cities
No full text Solid Management is a concern in East African capital cities. The absence of managing solid waste is a serious problem. An ever bigger concern is the growing quantities of waste that are generatedat households level in informal settlements. In most cases proper safeguard measures are largely ineffective or not in place at all. Moreover, unsafe disposal of waste in the region is coupled with poor hygiene. There is no doubt that East African capital cities need to formulate effective ways to manage their waste. This book is a result of PhD research within the framework of the PROVIDE project funded by INREF and carried out in East African capital cities (Dar es Salaam, Nairobi and Kampala). The work was carried out at the Environmental Policy (ENP) group with professor Gert Spaargaren and Dr. Peter Oosterveer as promotor and co-promotor. The focus of the research was to highlight the role of households in the production and management of domestic solid wastes. </p
A critical assessment of the paradigms for solid waste management in Pacific Island countries
No full textSolid waste management (SWM) in the Pacific Islands has not progressed much over the past four decades. For example, its technical and functional aspects can be succinctly described as being primarily concerned with the collection, disposal and open burning of wastes in landfills (most of which are dumps). The current state of SWM is posited to be underpinned by the paradigms informing SWM. Paradigms model problems and rationalise the course and types of actions taken to resolve problems within any practical field. Consequently, this study critically assessed prevailing paradigms of SWM at the global and regional levels, and examined if there was a need for an alternative paradigm for SWM in Pacific Island Countries (PICs).
The two overarching paradigms of solid waste management recognised globally are public health and environmental protection. The latter is at present the core paradigm for solid waste management, and it also has a number of derivatives which are also considered by their adherents as paradigms in their own right. In PICs, both overarching paradigms underpin SWM with public health protection showing overall dominance because of the historical association of SWM and public health, and the existing legislations and institutional arrangements.
The impacts and influence of these overarching paradigms were examined in detail using a set of indicator wastes within the context of Honiara, the capital of Solomon Islands. Although prevailing paradigms were relevant, they exacerbated SWM problems, limited management
options and alienated the biophysical and socioeconomic conditions of Honiara from SWM. Consequently a systems based paradigm was proposed and tested on a set of indicator wastes in Honiara, the capital of the Solomon Islands. At the operational level, the systems paradigm advocates for the expansion of SWM interventions across its three sub-systems: (a) material system, (b) consumer system and (c) solid waste system. The systems paradigm offered a fresh perspective on SWM in PICs, and stands out as a potential paradigm for SWM in PICs

PROBLEMS OF DETERMINING THE BALANCE OF RIGHTS BETWEEN THE AUTHOR AND THE SOCIETYABOUT THE USE OF INTELLECTUAL PROPERTY IN THE HISTORY OF LEGAL STUDIES
No full textThe article is dedicated to the problem of defining the boundaries of fair use of the composition. By the end of the 18th century compositions became unique and original. Authorship wasn't evaluated from the standpoint of traditionalism. It was connected with genius of the author, originality of creativity. Philosophers, for example I. Kant, J. G. Fichte, G. W. F. Hegel, started considering the concepts of author, ideas, and forms of the composition. The article explains what the idea and form is, comparison of these concepts, and why forms of the composition should be protected by law while the idea can be spread easily. Also the article explains the factors and legal grounds of non-classical concept's appearance due to the increasing complexity of public relations
Heteronanocrystal Transformations through In-situ Transmission Electron Microscopy
No full textSynthesis of nanocrystals (NCs) and heteronanocrystals (HNCs) has developed very fast particularly in the last decade. Nowadays, various structures and different morphologies of NCs and HNCs can be prepared with a very narrow size distribution. The nanoscale dimensions of these crystals lead to interesting phenomena (e.g. electronic properties) that are not found in their bulk counterparts. Therefore, NC and HNC research is now a hot topic in materials science and applied physics. Despite having interesting properties, the stability of NCs and HNCs is an issue outside the solution in which they are suspended. This raises a concern for their potential applications. Regarding their thermal stability, a number of studies have been reported showing morphological as well as chemical transformations with changing temperature. In this thesis, the focus is on in-situ heat induced transformations of HNCs and detailed characterization of these transformations through advanced transmission electron microscopy (TEM) techniques. Two processes were observed through in-situ heat treatment of the CdSe–CdS–ZnS core–multishell system: diffusion and simultaneous evaporation of different species. The structure evolves into a CdxZn1?xSe–CdyZn1?yS core–shell system through Zn inner diffusion and simultaneous partial evaporation of Cd and S. A more complex transformation is a temperature induced reconfiguration in the FexO/CoFe2O4 core/shell system. In this case, the FexO diffuses out of the core location and segregates at the outside of the CoFe2O4 shell. At the same time, the CoFe2O4 shell shrinks and fills the core volume. Co diffusion into the FexO structure is also observed with heating. Furthermore, in-situ heating studies of the CdSe-PbSe dumbbell system (a CdSe nanorod with PbSe NC tips) have shown a novel epitaxial nanowire growth process. Upon heating, PbSe starts to grow into CdSe with simultaneous Cd evaporation. This process proceeds as a cation exchange mechanism, whereby Pb is replacing Cd in CdSe. The crystal structure changes epitaxially at the same time from hexagonal wurtzite (CdSe) to cubic rock-salt (PbSe). Considering that the initial phases of CdSe and PbSe domains are solid and the final evaporation of Cd into the vapor phase, this novel epitaxial growth process is named solid–solid–vapor (SSV) growth. Observations reported in this thesis clearly show that transformations of HNCs upon heat treatment can differ significantly from one another. These studies can be regarded as first reference points when these HNC systems are considered to be implemented in possible future applications and for future in-situ heat treatment studies of HNCs.QN/Quantum NanoscienceApplied Science
