Att vara i Vara kommun : En studie om kommunens identitet, profil och image

Hugosson Koinberg, Madelene January 2014 (has links)
Abstract The aim of this paper is to investigate whether Vara municipality has a continuous picture of their identity, profile and image. Globalization has contributed to the increasingly growing of place marketing. Therefore, the study goes on to using the concepts of identity, profile and image to find out if Vara Municipality communicates similar throughout the whole organization and find out their all through core values. Globalisation will be an interpretive framework for the work that describes why the place marketing is becoming more pressing. The sense of place will be a central part of this study as it is the feelings and images of different places that will be described by the municipality together with the identity, profile and image. The method consists of structured- and semi-structured interviews and document analysis. The structured interviews were used to find out which image the neighboring municipalities had of the Vara Municipality and they were also used to find out the identity of the municipality by interview its own residents. The semi-structured interviews were used to find out the profile by interviewing the quality- and HR-manager of Vara municipality. The results and analysis concludes that Vara municipality has two central values of the municipality that is consistently in identity, profile and image, these values are culture and entrepreneurship. The identity and the image had several similarities but the profile was very different comparing to the image of the neighboring municipalities and its own residents. This may be because the profile represents what the municipality want others to see, and can be a bit of a ”belief in the future”. Wara municipality needs to work on the profile if they want a consistent image so it fits better with their identity and image.

The functional characterization of the SnRK1 protein complex in hybrid poplar

Lam, Kimberley SW 11 1900 (has links)
The sucrose-nonfermenting-1 related kinase 1 (SnRK1) protein complex is a heterotrimeric serine/threonine protein kinase complex conserved in eukaryotes that acts as a regulator of carbon metabolism and energy homeostasis. The objective of this study was to determine if the SnRK1 protein complex has a role in the nitrogen response and during dormancy acquisition in poplar. Gene expression profiling of the PtdSnRK1, PtdAKINbeta, and PtdAKINgamma gene family members was carried out using a robust qRT-PCR assay. A subset of these genes showed modified expression patterns under differential nitrogen availability and during dormancy acquisition, suggesting that SnRK1 complexes comprised of specific subunits may be involved in the regulation of the response to nitrogen and during dormancy acquisition. The regulatory subunits PtdAKINbeta1.1, PtdAKINgamma1.1 and PtdAKINgamma2.3 were often identified using principal component analysis as significantly responsible for distinguishing treatments from one another and therefore merit further study. / Plant Biology

Research and Development of Low-Profile, Small Footprint Antennas for VHF-UHF Range Applications

Olaode, Olusola January 2012 (has links)
<p>Efficient, but low-profile and small-footprint antennas for VHF-UHF range applications remains an ongoing work. VHF range spans approximately 54 - 88 MHz while UHF roughly ranges from 174 - 890 MHz. The inverse relationship between the physical length and resonant frequency of an antenna, which is a measure of its operating frequency range, is well known. A direct correlation between an antenna's physical length and radiation efficiency has also been established. Therefore, a combination of these constraints complicates the design of low-frequency antennas that have small physical size but with enough radiation resistance to be an efficient radiator when connected to a source having a comparable resistance. Given the frequency bands above, their corresponding wavelengths will be: 3.4-5.5 m (VHF) and 0.3-1.7 m (UHF). The length of an antenna operating at these wavelengths would need to be electrically-small i.e. a fraction of wavelength given size constraints for applications such as defense or commercial mobile communication equipment. As a consequence, the radiation resistance of the antenna, which is a function of its radiation efficiency, is greatly reduced. In other words, the input impedance or radiation impedance (assuming negligible ohmic losses in the antenna structure) features a small resistive component and a large capacitive component, causing reflections of most of the incident power to the antenna. Highly-reactive antennas are not desired for most transmitters and receivers. Therefore, the radiation resistance of an antenna must be increased by increasing its electrical length while simultaneously maintaining a low profile and footprint. This aim can be achieved by configuring the antenna to excite a resonance at, or very close to a desired operating frequency. An approach that I will explore in this dissertation is to exploit the broadband characteristics of meander-line and helical (or "spiral") antennas typically applied in the microwave frequency range to the UHF-VHF range. I will also propose novel antenna geometries that combine spiral and meander-line properties and analyze their performance. These antennas offer significant size reductions; for example, a bowtie meander dipole antenna studied yielded a height reduction of 55% at 64 MHz relative to a half-wave dipole antenna of the same resonant frequency. In addition, I will present a set of equations developed for predicting the fundamental resonant frequency and radiation resistance of meander-line antennas.</p> / Dissertation

Form and function of the Waihao-Wainono barrier, South Canterbury.

Stapleton, Joanne Maree January 2005 (has links)
The mixed sand and gravel barrier beaches located on the South Island's East Coast are formed predominantly of Greywacke, eroded from the mountains, and transported via the major river systems. These barriers act as the interface between the South Pacific Ocean and the surrounding hinterland. In times of high energy coastal events, breaching is common. This thesis examines the form and function of the Waihao-Wainono barrier, a section of the coastline situated north of the Waitaki River. Breaches along this part of the barrier are frequent and several have rendered the surrounding farmland unusable for several years due to the effects of saltwater inundation. There is some concern among the local community as to exactly why the barrier breaches at certain locations and not others, making land planning and management a difficult task for farmers. Several of the local landowners believe that since the construction of the Waitaki Dam in 1935, a significant decrease in sediment size along the barrier has occurred. It is also thought that the barrier form has experienced substantial change. Through the use of physical techniques used in the field of coastal science, 17 sites along the Waihao-Wainono barrier were studied. Excavations were carried out, surface and substrate profiles recorded and sediment samples collected from the surface. sub-surface and substrate of the barrier. Analysis of the barrier form and barrier volume concluded that the past breach sites consisted of steeper lower foreshore slopes than the non-breach sites, and at two sites, the substrate was not reached. Breach areas display the greatest barrier volume of all the study sites, which is contrary to belief. In relation to the surface sediments, the majority of barrier profiles displayed the distinct mean grain size cross shore zonation, characteristic of mixed sand and gravel beaches. The best and most consistent surface sorting was also identified as being a characteristic of the breach sites. The sediment size is not shown to have drastically reduced over the thirty year sampling period as was perceived by the local community. Within the sub-surface of the barrier, the sediments displayed chaotic sizes and generally poorly sorted material. Several of the breach sites contained a distinct change in sediment size between the coarser surface layer and the finer layer located immediately below. This layering of coarse and fine sized sediments leads to differences in permeability within the barrier, which is thought to be a major factor in why these sites have breached. Resulting from these findings, a group of characteristics of breach sites was formed and several predictions made as to where the barrier may breach in the near future.

Global Behavior Of Finite Energy Solutions To The Focusing Nonlinear Schr&ouml;dinger Equation In d Dimension

January 2011 (has links)
abstract: Nonlinear dispersive equations model nonlinear waves in a wide range of physical and mathematics contexts. They reinforce or dissipate effects of linear dispersion and nonlinear interactions, and thus, may be of a focusing or defocusing nature. The nonlinear Schrödinger equation or NLS is an example of such equations. It appears as a model in hydrodynamics, nonlinear optics, quantum condensates, heat pulses in solids and various other nonlinear instability phenomena. In mathematics, one of the interests is to look at the wave interaction: waves propagation with different speeds and/or different directions produces either small perturbations comparable with linear behavior, or creates solitary waves, or even leads to singular solutions. This dissertation studies the global behavior of finite energy solutions to the $d$-dimensional focusing NLS equation, $i partial _t u+Delta u+ |u|^{p-1}u=0, $ with initial data $u_0in H^1,; x in Rn$; the nonlinearity power $p$ and the dimension $d$ are chosen so that the scaling index $s=frac{d}{2}-frac{2}{p-1}$ is between 0 and 1, thus, the NLS is mass-supercritical $(s>0)$ and energy-subcritical $(s<1).$ For solutions with $ME[u_0]<1$ ($ME[u_0]$ stands for an invariant and conserved quantity in terms of the mass and energy of $u_0$), a sharp threshold for scattering and blowup is given. Namely, if the renormalized gradient $g_u$ of a solution $u$ to NLS is initially less than 1, i.e., $g_u(0)<1,$ then the solution exists globally in time and scatters in $H^1$ (approaches some linear Schr"odinger evolution as $ttopminfty$); if the renormalized gradient $g_u(0)>1,$ then the solution exhibits a blowup behavior, that is, either a finite time blowup occurs, or there is a divergence of $H^1$ norm in infinite time. This work generalizes the results for the 3d cubic NLS obtained in a series of papers by Holmer-Roudenko and Duyckaerts-Holmer-Roudenko with the key ingredients, the concentration compactness and localized variance, developed in the context of the energy-critical NLS and Nonlinear Wave equations by Kenig and Merle. One of the difficulties is fractional powers of nonlinearities which are overcome by considering Besov-Strichartz estimates and various fractional differentiation rules. / Dissertation/Thesis / Ph.D. Mathematics 2011

The Effect of Managerial Reputation on Corporate Tax Avoidance

Kim, Jin Wook, Kim, Jin Wook January 2012 (has links)
Prior literature suggests that tax avoidance is an effective way to enhance firm value. However, there appears to be considerable cross-sectional variation in tax avoidance, and it is not clear why some firms do not take full advantage of the tax avoidance opportunities being used by others. This study examines whether managerial reputation, as proxied by high-profile awards to top managers, is helpful in explaining corporate tax avoidance. The empirical results show that, relative to a matched control group, firms managed by a celebrity manager have significantly higher cash and GAAP effective tax rates in the three year period following the manager's first award than preceding the award. This result is consistent with the conjecture that celebrity managers, for fear of being labeled as "poor citizens," engage in less tax avoidance once they have an established reputation.

Rep-Index : uma abordagem abrangente e adaptável para identificar reputação acadêmica / Rep-Index : a comprehensive and adaptable approach to identify academic reputation

Cervi, Cristiano Roberto January 2013 (has links)
A tarefa de avaliar a produção científica de um pesquisador é fortemente baseada na análise de seu currículo. É o que fazem, por exemplo, as agências de fomento à pesquisa e desenvolvimento ou comissões de avaliação, quando necessitam considerar a produção científica dos pesquisadores no processo de concessão de bolsas e auxílios, na seleção de consultores e membros de comitês, na aprovação de projetos ou simplesmente para avaliar o conceito de um programa de pós-graduação. Nesse contexto, a modelagem de perfis de pesquisadores é tarefa fundamental, especialmente quando se quer avaliar a reputação dos pesquisadores. Isto pode ocorrer por meio de um processo de análise da trajetória de toda a carreira científica do pesquisador. Tal processo envolve não somente aspectos relacionados a artigos ou livros publicados, mas também por outros elementos inerentes à atividade de um pesquisador, como orientações de trabalhos de mestrado e de doutorado; participação em defesas de mestrado e de doutorado; trabalhos apresentados em conferências; participação em projetos de pesquisa, inserção internacional, dentre outros. O objetivo deste trabalho é especificar um modelo de perfil de pesquisadores (Rep- Model) e uma métrica para medir reputação acadêmica (Rep-Index). O processo de modelagem do perfil envolve a definição de quais informações são relevantes para a especificação do perfil e as apresenta por meio de 18 elementos e 5 categorias. O processo para medir a reputação do pesquisador é definido por uma métrica que gera um índice. Esse índice é calculado mediante a utilização dos elementos constantes no perfil do pesquisador. Para avaliar a abordagem proposta na tese, diversos experimentos foram realizados. Os experimentos envolveram a avaliação dos elementos do Rep-Model por meio de análise de correlação e por algoritmos de mineração de dados. O Rep-Index também foi avaliado e correlacionado com duas métricas amplamente utilizadas na comunidade científica, o h-index e o g-index. Como baseline, foram utilizados todos os pesquisadores do CNPq das áreas de Ciência da Computação, Economia e Odontologia. O trabalho desenvolvido nesta tese está inserido no contexto da identificação da reputação de pesquisadores no âmbito acadêmico. A abordagem desta tese tem como premissa ser abrangente e adaptável, pois envolve a vida científica do pesquisador construída ao longo de sua carreira científica e pode ser utilizada em diferentes áreas e em diferentes contextos. / The task of evaluating the scientific production of a researcher is based strongly on the analysis of their curriculum. It's what makes the agencies for research support or evaluation committees, when they need to consider the scientific production of researchers in the process of awarding grants and aid in the selection of consultants and committee members in approving projects or simply to assess the concept of a program graduate. In that context, the modeling of profiles of researchers is fundamental task especially when one wants to evaluate the reputation of the researchers. This can occur by means of a process of analysis of the trajectory of all the scientific career of the researcher. Such process involves not only aspects related to papers or books, but also other elements inherent in the activity of a researcher, as orientations of master’s degree and doctorate; participation in defense of master's and doctoral degrees; papers presented in conferences, participation in research projects, international integration, among others. This proposal specifies a profile template for researchers (Rep-Model) and a metric to measure academic reputation (Rep-Index). The profile modeling process involves define which information is relevant to the specification of the profile and shows through 18 elements and 5 categories. The process for measuring researcher's reputation is defined by a metric that generates an index. This index is calculated by using the information contained in the profile of the researcher. To evaluate the approach proposed in the thesis, extensive experiments were conducted. The experiments involved the evaluation of Rep-Model by means of correlation analysis and data mining algorithms. The Rep-Index was also evaluated and correlated with two metrics widely used in the scientific community, the h-index and gindex. As a baseline, all of CNPq researchers in the areas of Computer Science, Economics and Dentistry were used. The work in this thesis is set in the context of identifying the reputation of researchers within the academic sphere. The approach of this thesis is premised be comprehensive and adaptable, because it involves the life science researcher built throughout his scientific career and can be used in different research areas and in different contexts.
