Value creation through sponsorship in electronic sports

The objective of this thesis was to study value creation through sponsor-ship in a new emerging electronic sports environment. Sub-questions were formulated which helped in finding answers to the main research question. Theory of traditional sports and practice of electronic sports were compared with each other in order to find out how theories of tradi-tional sports fare in the new environment. B2B-relationship model of Actors, resources and activities is used in this thesis to help in clarifying the different variables used in electronic sports sponsorship environment. The empirical research was conducted via interviews with the managers working in electronic sports environment. One of the main conclusions is that relationship management is really important.. Actors in electronic sports need to find and create win-win-win situations. This means that they need to benefit the actors in sponsoring relationship and also the community.

First-principles study on electronic and structural properties of Cu(In/Ga)Se alloys for solar cells

Thin-film photovoltaic solar cells based on the Cu(In1−xGax)Se2 (CIGS) alloys have attracted more and more attention due to their large optical absorption coefficient, long term stability, low cost, and high efficiency. Modern theoretical studies of this material with first-principles calculations can provide accurate description of the electronic structure and yield results in close agreement with experimental values, but takes a large amount of calculation time. In this work, we use first-principles calculations based on the computationally affordable meta- generalized gradient approximation of the density-functional theory to investigate electronic and structural properties of the CIGS alloys. We report on the simulation of the lattice parameters and band gaps, as a function of chemical composition. The obtained results were found to be in a good agreement with the available experimental data.

Power Electronic Converters in Low-Voltage Direct Current Distribution – Analysis and Implementation

Over the recent years, smart grids have received great public attention. Many proposed functionalities rely on power electronics, which play a key role in the smart grid, together with the communication network. However, “smartness” is not the driver that alone motivates the research towards distribution networks based on power electronics; the network vulnerability to natural hazards has resulted in tightening requirements for the supply security, set both by electricity end-users and authorities. Because of the favorable price development and advancements in the field, direct current (DC) distribution has become an attractive alternative for distribution networks. In this doctoral dissertation, power electronic converters for a low-voltage DC (LVDC) distribution system are investigated. These include the rectifier located at the beginning of the LVDC network and the customer-end inverter (CEI) on the customer premises. Rectifier topologies are introduced, and according to the LVDC system requirements, topologies are chosen for the analysis. Similarly, suitable CEI topologies are addressed and selected for study. Application of power electronics into electricity distribution poses some new challenges. Because the electricity end-user is supplied with the CEI, it is responsible for the end-user voltage quality, but it also has to be able to supply adequate current in all operating conditions, including a short-circuit, to ensure the electrical safety. Supplying short-circuit current with power electronics requires additional measures, and therefore, the short-circuit behavior is described and methods to overcome the high-current supply to the fault are proposed. Power electronic converters also produce common-mode (CM) and radio-frequency (RF) electromagnetic interferences (EMI), which are not present in AC distribution. Hence, their magnitudes are investigated. To enable comprehensive research on the LVDC distribution field, a research site was built into a public low-voltage distribution network. The implementation was a joint task by the LVDC research team of Lappeenranta University of Technology and a power company Suur-Savon S¨ahk¨o Oy. Now, the measurements could be conducted in an actual environment. This is important especially for the EMI studies. The main results of the work concern the short-circuit operation of the CEI and the EMI issues. The applicability of the power electronic converters to electricity distribution is demonstrated, and suggestions for future research are proposed.

Changing roles of nurse educators employed in acute and chronic care settings : the impact of professional and statutory mandates in Ontario at four sites of one hospital corporation /

The role of the hospital-employed nurse educator is evolving. Factors influencing this change include the introduction of standards for nurse educators by the College of Nurses of Ontario (CNO), a change in the way nurses are educated, the emergence of nursing as a profession, and hospital restructuring as a result of budgetary constraints. Two of these influencing factors: the introduction of the updated Standards of Practice for Registered Nurses and Registered Practical Nurses (1996) and hospital restructuring occurred over the last 7 years at several hospitals in southern Ontario. Current literature as well as the Standards of Practice (1996) were utilized to examine the current roles and responsibilities of nurse educators and subsequently develop a questionnaire to study the impact of these influencing factors on the role of the nurse educator. This questionnaire was piloted and revised before its distribution at 4 hospitals in southern Ontario. Twenty-five of the 41 surveys (61%) distributed were returned for analysis. The data reflected that the Standards of Practice had a positive influence on the role of the nurse educator, while hospital restructuring had a negative impact. In addition, many of the roles and responsibilities identified in the literature were indeed part of the current role of nurse educators, as well as several responsibilities not captured in the literature. The predictions for the future of this role in its current state were not positive given the financial status of the health care system as well as the lack of clarity for the role and the current level ofjob satisfaction among practicing nurse educators. However, a list of recommendations were generated which, if implemented, could add clarity to the role and improve job satisfaction. This could enhance the retention of current nurse educators and the possibility of recruiting competent nurse educators to the role in the future.

Comparing ESL electronic and face-to-face pre-writing conferences and first drafts : discourse, participation, and idea transfer /

This study was a comparative investigation of face-toface (i.e., proximate) and computer-mediated written (i.e., graphic) pre-writing conferences. The participants in this study were advanced English as a second language students. The 2 types of conferences were compared in terms of textual features, participation, and the . degree to which they were on topic. Moreover, drafts written after the 2 types of conferences were compared in terms of textual features, and the degree to which they were related to the conferences. Students produced an equivalent amount of discourse in an equivalent amount of time in the 2 types of conferences. The discourse in graphic conferences displayed greater lexical range, and some evidence suggests that it was less on-topic. Both these results likely occurred because the graphic conferences contained more discourse demonstrating interactive competence. Participation in graphic conferences was found to be as balanced or more balanced among students, and among students and the group leader combined. Overall, the drafts produced after the 2 types of conferences were of equivalent length and topical range, but some evidence suggests that drafts written after proximate conferences were more related to the conferences.

Modernizing human resource management : the importance of values-based leadership in the Canadian federal public service /

Over the past several decades, many theories have been advanced as to why efforts to reform the public service have met with only limited success. Clearly, the role of leadership with respect to reform must be examined, since successful organizational leaders should be extremely accomplished in the promotion and protection of the values that underlie decision-making. The issue of effective leadership is particularly significant for the future of the public service of Canada. Large numbers of public servants in the executive ranks are due to retire within the next five years. Given their central role, it is vital that there be enough dedicated and committed public servants to staff future vacancies. It is also essential that future public service leaders possess the competencies and values associated with a world-class public service and, a new type of public organization. Related to this point is the importance of people-management skills. People management in the public service is an issue that has historically faced - and will continue to face - major challenges with respect to recruiting and retaining the leaders it requires for its continued success. It is imperative that the public service not only be revitalized and be seen as an employer of choice, but also that the process by which it accomplishes this goal - the practice of human resource management - be modernized. To achieve the flexibility needed to remain effective, the public service requires the kind ofleadership that supports new public service values such as innovation and which emphasizes a "people- first" approach. This thesis examines the kind of public service leadership needed to modernize the human resource management regime in the federal public service. A historical examination of public service values is presented to help determine the values that are important for public service leaders with respect to modernizing human resource management. Since replenishing the 2 ranks of public service leaders is crucial to ensure the quality of service to Canadians, leadership that supports career planning will be a major focus of this paper. In addition, this thesis demonstrates that while traditional public service values continue to endure, innovative leaders must effectively reconcile new public service values with traditional values in order to increase the possibilities for successful reform as well as achieve business objectives. Much of the thesis is devoted to explaining the crucial role of post-bureaucratic leadership to successful reform. One of the major findings of the thesis is that leaders who demonstrate a blending of new public service values and traditional values are critical to creating effective employment relationships, which are key to modernizing human resource management in the federal public service. It will be apparent that public service leaders must ensure that an appropriate accountability framework is in place before embarking on reform. However, leaders who support new public service values such as innovation and empowerment and who emphasize the importance of people are essential to successful reform.

Systematic studies of the effect of pressure on magnetic and electronic properties of La2/3Ca1/3MnO3 thin films with various thicknesses /

Interest in mixed-valent perovskite manganese oxides of La\-xAxMnO^ (v4-divalent alkaline earth Ca, Sr or Ba), whose unusual properties were discovered nearly a half century ago, has recently been revived. The discovery of the colossal magnetoresistance and pressure effects introduced new questions concerning the complex interplay between lattice structure, magnetism and transport in doped perovskite manganites. In this study, we report our experimental investigations of pressure and magnetic field dependencies of La-i/sCai/sMnOs (LCMO) epitaxial films with various thickness on SrTiO$ substrate. An analysis of film thickness dependency of the resistivity of LCMO epitaxial films under pressure and magnetic field has been performed by taking into account substrate contributions. This verifies the correlation of lattice distortion with magnetic and transport properties. Strong dependencies of Mn — O — Mn bond bending and Mn — O bond stretching with pressure as well as Mn spin alignment with magnetic field, and the lattice distortion induced by the substrate are discussed.

Diffusion Monte Carlo study of electronic properties for H and Be atoms /

We examined three different algorithms used in diffusion Monte Carlo (DMC) to study their precisions and accuracies in predicting properties of isolated atoms, which are H atom ground state, Be atom ground state and H atom first excited state. All three algorithms — basic DMC, minimal stochastic reconfiguration DMC, and pure DMC, each with future-walking, are successfully impletmented in ground state energy and simple moments calculations with satisfactory results. Pure diffusion Monte Carlo with future-walking algorithm is proven to be the simplest approach with the least variance. Polarizabilities for Be atom ground state and H atom first excited state are not satisfactorily estimated in the infinitesimal differentiation approach. Likewise, an approach using the finite field approximation with an unperturbed wavefunction for the latter system also fails. However, accurate estimations for the a-polarizabilities are obtained by using wavefunctions that come from the time-independent perturbation theory. This suggests the flaw in our approach to polarizability estimation for these difficult cases rests with our having assumed the trial function is unaffected by infinitesimal perturbations in the Hamiltonian.

Electronic and magnetic properties of LaV1-xO3 /

A series of LaVi^xOs compounds (x=0.00, 0.02, 0.04, 0.06, 0.08) were prepeired using the standard solid reaction. The samples were chareicterized by X-ray diffraction (XRD), fourprobe resistivity, smd magnetic susceptibility studies. Powder X-ray diffraction analysis indicated the formation of a single-phase sample with a orthorhombic structure which was first found in GdFeOs (space group Pnma) . The Unit Cell program was used for calculating lattice peirameters from XFID data. The XRD spectnim could be indexed on a cubic lattice with Og = 2ap ~ (7.8578 to 7.9414 A). The lattice parameter was observed to increase as the Vanadium vacancy increased. Four-probe resistivity measurements exhibited semiconductor behavior for all sajnples from room temperature down to 19K. The resistivity of samples increased with increasing Vanadium vacancy. The resistivity of samples demonstrated activated conduction with an activation energy of approximately 0.2 eV. The activation energy increased with increasing lattice parameter. Field cool magnetic susceptibility measurements were performed with field of 500 G from 300 K to 5 K. These measurements indicated the presence of an antiferromagnetic transition at about 140 K. The data was fitted above Neel temperature to Ciurie-Weiss law yielding a negative parameignetic Curie temperature. This implies that antiferromagnetic ordering is present.

Arsenic speciation by ion-exchange chromatography with on- line determination by hydride generation: electronic modification of the D.C. plasma by photon counting

A method using L-cysteine for the determination of arsenous acid (As(III)), arsenic acid (As(V)), monomethylarsonic acid (MMAA), and dimethylarsinic acid (DMAA) by hydride generation was demonstrated. The instrument used was a d.c. plasma atomic emission spectrometer (OCP-AES). Complete recovery was reported for As(III), As(V), and DMAA while 86% recovery was reported for MMAA. Detection limits were determined, as arsenic for the species listed previously, to be 1.2, 0.8, 1.1, and 1.0 ngemL-l, respectively. Precision values, at 50 ngemL-1 arsenic concentration, were f.80/0, 2.50/0, 2.6% and 2.6% relative standard deviation, respectively. The L-cysteine reagent was compared directly with the conventional hydride generation technique which uses a potassium iodide-hydrochloric acid medium. Recoveries using L-cysteine when compared with the conventional method provided the following results: similar recoveries were obtained for As(III), slightly better recoveries were obtained for As(V) and MMAA, and significantly better recoveries for DMAA. In addition, tall and sharp peak shapes were observed for all four species when using L-cysteine. The arsenic speciation method involved separation by ion exchange .. high perfonnance liquid chromatography (HPLC) with on-line hydride generation using the L.. cysteine reagent and measurement byOCP-AES. Total analysis time per sample was 12 min while the time between the start of subsequent runs was approximately 20 min. A binary . gradient elution program, which incorporated the following two eluents: 0.01 and 0.5 mM tri.. sodium citrate both containing 5% methanol (v/v) and both at a pH of approximately 9, was used during the separation by HPLC. Recoveries of the four species which were measured as peak area, and were normalized against As(III), were 880/0, 290/0, and 40% for DMAA, MMAA and As(V), respectively. Resolution factors between adjacent analyte peaks of As(III) and DMAA was 1.1; DMAA and MMAA was 1.3; and MMAA and As(V) was 8.6. During the arsenic speciation study, signals from the d.c. plasma optical system were measured using a new photon-signal integrating device. The_new photon integrator developed and built in this laboratory was based on a previously published design which was further modified to reflect current available hardware. This photon integrator was interfaced to a personal computer through an AID convertor. The .photon integrator has adjustable threshold settings and an adjustable post-gain device.

Rotation-electronic interaction in the 3p-complex Rydberg state of water

An energy theory is formulated for the rotational energy levels in a p-complex Rydberg state of an asymmetric top molecule of symmetry C2v. The effective Hamiltonian used consists of the usual rigid rotor Hamiltonian augmented with terms representing electronic spin and orbital angular momentum effects. Criteria for assigning symmetry species to the rotational energy levels, following Houganfs scheme that uses the full molecular group,are established and given in the form of a table. This is particularly suitable when eigenvectors are calculated on a digital computer. Also, an intensity theory for transitions to the Rydberg p-complex singlet states is presented and selection rules in terms of symmetry species of energy states are established. Finally, applications to HpO and DpO are given.
