Developing the synthetic control required for the intentional 3-D arrangement of atoms remains a holy grail in crystal engineering and materials chemistry. The explosive development of metal-organic materials in recent decades has shed light on the above problem. Their properties can be tuned by varying the organic and/or inorganic building units. In addition, their crystallinity makes it possible to determine their structures via the X-ray diffraction method. This dissertation will focus on the chemistry and applications of two kinds of metal-organic materials, namely, metal-organic frameworks (MOFs) and metal-organic polyhedra (MOP). MOFs are coordination polymers. Their permanent porosity makes them a good “gas sponge”. In the first section, an isoreticular series of MOFs with dendritic hexacarboxylate ligands has been synthesized and characterized structurally. One of the MOFs in this series, PCN-68, has a Langmuir surface area as high as 6033 m2 g-1. The MOFs also possess excellent gas (H2, CH4, and CO2) adsorption capacity. In the second section, a NbO-type MOF, PCN-46, was constructed based on a polyyne-coupled di-isophthalate linker formed in situ. Its lasting porosity was confirmed by N2 adsorption isotherm, and its H2, CH4 and CO2 adsorption capacity was examined at 77 K and 298 K over a wide pressure range (0-110 bar). Unlike MOFs, MOP are discrete porous coordination nanocages. In the third section, a MOP covered with bulky triisopropylsilyl group was synthesized, which exhibits a thermosensitive gate opening property. This material demonstrates a molecular sieving effect at a certain temperature range, which could be used for gas separation purpose. In the last section, a MOP covered with alkyne group was synthesized through kinetic control. The postsynthetic modification via click reaction with azide-terminated polyethylene glycol turned them into metallomicelles, which showed controlled release of an anticancer drug 5-fluorouracil. In summary, two kinds of metal-organic materials have been discussed in this dissertation, with the applications in gas storage, gas separation, and drug delivery. These findings greatly enrich the chemistry and applications of metal-organic materials.

The idea of ¡¥semi-presidential system¡¦ was proposed by Duverger (1980), and it aroused substantial following studies. Newly rising democratic countries have also adopted semi-presidential system. After 1990, Taiwan also adopted a semi-presidential systems right after the constitution revised. As the member of the system, the understanding and improvement of theoretical and practical for the system is necessary and timing. This study will plan to compare the constitutional frameworks and operational types of semi-presidential countries between France and Taiwan. We try to find the variables that influence the constitutional operation. We expect this study can provide a causal model for the further empirical research. After compare the constitutional statues and its operations difference between France and Taiwan, we have the constitutional statues boundary of semi-presidential system. We also have the constitutional operations basic rule by constitutional interpretation. To be a normative constitution, that is, its norms govern the political process or the power process adjusts itself to the norms, constitutional operations should be operate between the ¡§boundary¡¨ and the ¡§basic rule¡¨. We expect this study can provide a dialogue platform between political science and law and construct an operative standard for judicial review.

Information technology usage has become compulsory for all organizations whether government or private organizations to achieve visibility, compete rivals and execute their missions better. To get desired result from usage of information technology, IT of organization has to be managed well. Up till now, various frameworks are developed to manage it well. Best examples for this kind of frameworks are COBIT and ITIL, containing all processes which can be handled in IT management and becoming widespread through the world. COBIT and ITIL are complementary frameworks rather than competitors. Due to this reason, organizations must implement both of them instead of choosing one of them. In addition to these, ISO/IEC 27001:2005 which focuses on information security management process is a quite famous IT standard in terms of security. This thesis provides organizations to meet requirements of these frameworks/standards which are process based frameworks and standards complementary to each other, with a unique implementation by taking unification of processes in a more simple and understandable way. Consequently, it provides reduction in the duplicate work and prevents inconsistencies that may occur. In addition, including CMMI level two requirements motivate the organization to implement higher maturity level of CMMI. Moreover, this study provides organizations to implement ISO 27001 management structure which establish a foundation for extension to technical structure of it. Besides these, this study provides an alignment of frameworks model and COBIT and ITIL which helps organization to trace ITIL and COBIT simultaneously. Lastly by providing a web based application, there exists foundation for knowledge bank of IT processes in Turkish and profile pages for each organization to manage, trace and reach their own IT processes in a digital environment.

Metal-organic frameworks (MOFs) or porous coordination polymers (PCPs) have become the focus of intense study over the past decade due to their potential for advancing a variety of applications including air purification, gas storage, adsorption separations, catalysis, gas sensing, drug delivery, and so on. These materials have some distinct advantages over traditional porous materials such as the well-defined structures, uniform pore sizes, chemically functionalized sorption sites, and potential for post-synthetic modification, etc. Thus, synthesis and adsorption studies of porous MOFs have increased substantially in recent years. Among various prospective applications, air purification is one of the most immediate concerns, which has urgent requirements to improve current nuclear, biological, and chemical (NBC) filters involving commercial and military purposes. Thus, the major goal of this funded project is to search, synthesize, and test these novel hybrid porous materials for adsorptive removal of toxic industrial chemicals (TICs) and chemical warfare agents (CWAs), and to install the benchmark for new-generation NBC filters. The objective of this study is three-fold: (i) Advance our understanding of coordination chemistry by synthesizing novel MOFs and characterizing these porous coordination polymers; (ii) Evaluate porous MOF materials for gas-adsorption applications including CO2 capture, CH4 storage, other light gas adsorption and separations, and examine the chemical and physical properties of these solid adsorbents including thermal stability and heat capacity of MOFs; (iii) Evaluate porous MOF materials for next-generation NBC filter media by adsorption breakthrough measurements of TICs on MOFs, and advance our understanding about structure-property relationships of these novel adsorbents.

<p>This dissertation concerns the application of a method for developing context dependent CASE-tool evaluation frameworks. Evaluation of CASE-tools prior to adoption is an important but complex issue; there are a number of reports in the literature of the unsuccessful adoption of CASE-tools. The reason for this is that the tools have often failed in meeting contextual expectations. The genuine interest and willingness among organisational stakeholder to participate in the study indicate that evaluation of CASE-tools is indeed a relevant problem, for which method support is scarce.</p><p>To overcome these problems, a systematic approach to pre-evaluation has been suggested, in which contextual demands and expectations are elucidated before evaluating technology support.</p><p>The proposed method has been successfully applied in a field study. This dissertation contains a report and reflections on its use in a specific organisational context. The application process rendered an evaluation framework, which accounts for demands and expectations covering the entire information systems development life cycle relevant to the given context.</p><p>The method user found that method transfer was indeed feasible, both from method description to the analyst and further from the analyst to the organisational context. Also, since the span of the evaluation framework and the organisation to which the method was applied is considered to be large, this indicates that the method scales appropriately for large organisations.</p>

Propylene is one of the most important feedstocks of the petrochemical industry with an estimated 2015 worldwide demand of 100 million tons. Retrofitting conventional C3 splitters is highly desirable due to the huge amount of thermal energy required to separate propylene from propane. Membrane separation is among the alternatives that both academia and industry have actively studied during the past decades, however; many challenges remain to advance membrane separation as a scalable technology for energy-efficient propylene/propane separations. The overarching goal of this research is to provide a framework for development of scalable ZIF-based mixed-matrix membrane that is able to deliver attractive transport properties for advanced gas separations. Zeolitic imidazolate frameworks (ZIFs) were pursued instead of conventional molecular sieves (zeolites and carbon molecular sieves) to form mixed-matrix membrane due to their intrinsic compatibility with high Tg glassy polymers. A systematic study of adsorption and diffusion in zeolitic imidazolate framework-8 (ZIF-8) suggests that this material is remarkably kinetically selective for C3 and C4 hydrocarbons and therefore promising for membrane-based gas separation and adsorptive separation. As a result, ZIF-8 was used to form mixed-matrix dense film membranes with polyimide 6FDA-DAM at varied particle loadings and it was found that ZIF-8 significantly enhanced propylene/propane separation performance beyond the “permeability-selectivity” trade-off curve for polymeric materials. Eventually, this research advanced ZIF-based mixed-matrix membrane into a scalable technology by successfully forming high-loading dual-layer ZIF-8/6FDA-DAM asymmetric mixed-matrix hollow fiber membranes with attractive propylene/propane selectivity.

Metal-Organic Materials (MOMs) represent an important class of solid-state crystalline materials. Their countless attractive attributes make them uniquely suited to potentially resolve many present and future utilitarian societal challenges ranging from energy and the environment, all the way to include biology and medicine. Since the birth of coordination chemistry, the self-assembly of organic molecules with metal ions has produced a plethora of simple and complex architectures, many of which possess diverse pore and channel systems in a periodic array. In its infancy however this field was primarily fueled by burgeoning serendipitous discoveries, with no regard to a rational design approach to synthesis. In the late 1980s, the field was transformed when the potential for design was introduced through the seminal studies conducted by Hoskins and Robson who transcended the pivotal works of Wells into the experimental regime. The construction of MOMs using metal-ligand directed assembly is often regarded as the origin of the molecular building block (MBB) approach, a rational design strategy that focuses on the self-assembly of pre-designed MBBs having desired shapes and geometries to generate structures with intended topologies by exploiting the diverse coordination modes and geometries afforded by metal ions and organic molecules. The evolution of the MBB approach has witnessed tremendous breakthroughs in terms of scale and porosity by simply replacing single metal ions with more rigid inorganic metal clusters whilst preserving the inherent modularity and essential geometrical attributes needed to construct target networks for desired applications. The work presented in this dissertation focuses upon the rational design and synthesis of a diverse collection of open frameworks constructed from pre-fabricated rigid inorganic MBBs (i.e. [M(CO2)4], [M2(RCO2)4], [M3O(RCO2)6], MN3O3, etc), supermolecular building blocks (SBBs) and 3-, 4- and 6-connected organic MBBs. A systematic evaluation concerning the effect of various structural parameters (i.e. pore size and shape, metal ion, charge, etc) on hydrogen uptake and the relative binding affinity of H2-MOF interactions for selected systems is provided.

Metal--organic frameworks (MOFs) are porous crystalline materials that are synthesized from rigid organic ligands and metal-containing clusters. They are highly tunable as a number of different structures can be made by simply changing the organic ligand and/or metal ion. MOFs are a promising class of materials for many energy-related applications, including H2 storage and CO2 capture and sequestration. Computational studies can provide insights into MOFs and the mechanism of gas sorption and separation. Theoretical studies on existing MOFs are performed to determine what structural characteristics leads to favorable gas sorption mechanisms. The results from these studies can provide insights into designing new MOFs that are tailored for specific applications. In this work, grand canonical Monte Carlo (GCMC) simulations were performed in various MOFs to understand the gas sorption mechanisms and identify the favorable sorption sites in the respective materials. Experimental observables such as sorption isotherms and associated isosteric heat of adsorption, Qst, values can be generated using this method. Outstanding agreement with experimental measurements engenders confidence in a variety of molecular level predictions. Explicit many-body polarization effects were shown to be important for the modeling of gas sorption in highly charged/polar MOFs that contain open-metal sites. Indeed, this was demonstrated through a series of simulation studies in various MOFs with rht topology that contain such sites. Specifically, the inclusion of many-body polarization interactions was essential to reproduce the experimentally observed sorption isotherms and Qst values and capture the binding of sorbate molecules onto the open-metal sites in these MOFs. This work also presents computational studies on a family of pillared square grid that are water-stable and display high CO2 sorption and selectivity. These MOFs are deemed promising for industrial applications and CO2 separations. Simulations in these materials revealed favorable interactions between the CO2 molecules and the SiF62- pillars. Further, the compound with the smallest pore size exhibits the highest selectivity for CO2 as demonstrated through both experimental and theoretical studies. Many other MOFs with intriguing sorption properties are investigated in this work and their sorption mechanisms have been discerned through molecular simulation.

The overall aim of this study is to investigate the phenomenon of performance measurement in independently owned hotels in Ireland in order to understand the role of measurement in the management of the largest component of the hotel sector. The primary objectives of this study are to investigate the extent to which Irish hotel operators are utilising performance measurement techniques, to establish the rationale for the use of selected performance measures in independent hotels and to understand approaches to performance measurement in the management of independent hotels. A comprehensive investigation of existing performance management and measurement activity is provided in this study. A mixed methods approach to the research was undertaken to gather data on the phenomenon of performance measurement, allowing for a triangulation of data through multiple sources. A survey questionnaire was carried out within the hotels in Ireland followed by focus groups and indepth interviews carried out in a number of small and medium-sized hotels in Ireland. A number of key' performance measurement issues were investigated and include the rationale for performance measurement, the benefits of performance measurement, those responsible for carrying out the function, critical success factors impacting on the business and performance dimensions and measures utilised by hotel operators in the study. The findings of this research have implications for a number of stakeholders, however, the greatest impact will be on the small and medium-sized hotel operator. The research shows there is a need for these hotel operators to adopt a more structured formal approach to performance measurement. A number of models of performance measurement for small, medium-size and large hotels are proposed. These models will contribute to the management of performance in the hotel sector in Ireland, leading to increased effectiveness which is especially important in the current economic climate that the hotel and tourism sector is facing and will face into the future.
