Fashionable Strategies : Internationalization process of small and medium sized Nordicfashion companies

Barwinski, Arne, Burvall, Caroline January 2011 (has links)
In our master thesis “Fashionable strategies” we analyze the internationalization processof small and medium sized Nordic Fashion companies. In our study we conducted aquantitative survey and qualitative in-depths interviews to shed light on the topic. We usehereby an iterative research strategy through the triangulation analysis method as researchapproach. The combination of methodologies and perspectives allowed us to analyze ourtheoretical framework and the research questions in a favorable manner. The researchquestions we aim to investigate in our study were the following:· What are the reasons for the small and medium sized Nordic fashion companies wheninternationalizing, and what are the strategies the companies use hereby?· What influences the small and medium sized Nordic fashion companies in their choiceof strategy and market to enter?· Which barriers of entry and problems do the small and medium sized Nordic fashioncompanies see as critical in their internationalization process and how do theyovercome these issues?In the research we especially took a look at the following areas that we found mainlyimportant for fashion companies in their internationalization process: The reasons forexpanding, the choice of market, the entry modes that are used and barriers and problemsthat occur in the process. We take a view on the theoretical models of the Uppsala Model,Helsinki model, Revised Uppsala model and Born-Global Theory to explain the strategiesbehind the small and medium sized Nordic fashion companies.We see that the growth of the company and the profit increase are the main reasons for theNordic fashion companies when expanding their business. The entry modes used by thecompanies are agents and distributors, and when choosing the markets the fashioncompanies are contact-driven and focusing first on markets that have a rather smallerdistance to their own domestic market. The problems the companies have to overcome arecosts of entry, cash-flow and invoice payments which are all related to financial issues.We believe that our study has contributed with new information to the research field ofinternationalization concerning small medium fashion companies in the Nordic countries.

Experimental seismic surveys of the Trans-Hudson Orogen

Bezdan, Sandor 01 January 1998 (has links)
Two experimental seismic surveys were collected in the 1991 LITHOPROBE Trans-Hudson Orogen (THO) data acquisition program. The purpose of the coincident dynamite and vibroseis reflection surveys was to compare crustal images obtained using high-fold low-energy and low-fold high-energy sources. On single-fold field records, signal amplitudes from explosive sources are consistently 50 dB higher than on the corresponding vibroseis records. The vibroseis final stack exhibits better defined upper-crustal reflectivity due primarily to the higher fold. However, at lower-crustal and Moho levels, the dynamite data provides images which are equal or superior to those obtained from the vibroseis data. The dynamite source not only allowed deeper signal penetration but also succeeded in mapping of a number of subcrustal reflections not identified in previous vibroseis data. These new seismic images indicate that the crustal root is not simple depression on the upper-mantle as was inferred initially but a broad (3 s) zone of reflectivity that dips west and extends more than 10 km below the younger regional Moho. Moreover, the dynamite data also indicates that diffraction patterns, detected at lower crustal and Moho depths, have large apertures which permitted proper migration of these lower crustal events. Four vibroseis expanding spread profiles (ESP) were also acquired during the data acquisition program to obtain more detailed and accurate velocity structure. These profiles, with a maximum offset of 18 km, were centered on areas where prominent crustal reflectivity was detected by the regional vibroseis survey. The small source stepout distance (100 m) generated high-fold ($>$30) data. Extensive modeling was carried out to estimate the offset range within which each traveltime approximation and velocity analysis technique may be implemented. The results reveal that velocity estimation becomes more robust and accurate when crustal seismic surveys utilize longer offsets than commonly used. These larger source-receiver separations, however, must be generally limited to offset/depth ratios not exceeding 1.5 when conventional velocity analysis techniques, based on the hyperbolic moveout assumptions, are implemented. Besides the semblance method two velocity estimators adapted to crustal studies, namely the covariance and the $\tau$ - p techniques, were tried. The former yielded the highest resolution followed by the semblance and the $\tau$ - p methods. Resolution of the semblance estimator for a maximum offset of 36 km is equal to that of the covariance method with a corresponding offset of 18 km for mid-crustal reflectors. The advantages provided by the long-offset data acquisition include increased S/N ratio and a greater number of traces with sufficiently large moveouts whichimproved velocity resolution, especially below mid-crustal depths. To achieve similar advantages in a regional crustal reflection survey would require the adoption of longer spread lengths than those presently implemented in standard data acquisition procedures.

The Research and Discussion of the Promotion of the Local Employment Policy of R.O.C

Weng, Su-zu 30 August 2006 (has links)
The theme of the thesis is ¡§The Research and Discussion of the Promotion of the Local Employment Policy of R.O.C.¡¨ It is divided into five chapters. The first chapter, Introduction, is started with the unemployment problems caused by the worse and worse situations of politics and the economic environment and the related solutions of the government. Chapter Two, the Backgrounds and the Models of the Promotion of the Local Employment Policy of R.O.C., discusses a series of policies of re-establishment of employment, everlasting employment construction and multiple-employment development, etc. Chapter Three, The Evaluation of the Domestic promotion of local employment policy and related methods, evaluates the advantages and disadvantages of the local employment policy from the points of view of social efficiency and the efficiency of employment. Chapter Four, The Research and Discussion of the Experiences of the Promotion of Local Employment Policies of Foreign Countries, discusses the points which deserve our analyzing and learning, taking reference from the related academic theories and practical policies of USA, EU, Korea, etc. Chapter Five, Conclusion, claims the new thinking of combining the Third Party NGO of Multiple-Employment Development Policy and the benefits caused by the Policy of ¡§Deep Cultivation Localization¡¨ To reduce the rate of unemployment is the purpose of domestic promotion of the local employment policy. Although there appear many disadvantages during the process of practicing of the policy, generally speaking, multiple employment development policy has the advantages of reducing the rate of unemployment, the re-distribution of income, the balance between cities and countries, activating the re-building of the community life and the promoting of local economic development, etc. It is so-called Deep Cultivation Localization which presents the characters and the needs of the communities

Expanding Architecture / A Proposal For A Multi

Turgutoslu, Burak 01 January 2003 (has links) (PDF)
Standardization, flexibility and transparency had been the eminent keywords of Modern Architecture that have also provided material for the re-interpretation and re-production of several discussions on concepts like &lsquo / form&rsquo / and &lsquo / function&rsquo / in architecture. This study is an inquiry into a number of different interpretations that scrutinize the intricate relationship between architectural form and function in the 20th century with respect to the concepts defined above. The conceptualization of this thesis will be based on the assumption that function is an inadequate and weak concept for the generation of architectural form. It is in this context that form is accepted as an architectural &ldquo / fragment&rdquo / that attains its autonomy not from the strictures imposed by other architectural fragment like &lsquo / function&rsquo / , &lsquo / structure&rsquo / , &lsquo / program&rsquo / and &lsquo / site / but from an infinite number of internal relationships or &lsquo / design tools&rsquo / as we call. The aim of this study is to propose a project for &ldquo / A Multi &ndash / Functional Hall at METU&rdquo / which has the capability of expanding its limits in future, both physically and conceptually / and investigate the &lsquo / design tools&rsquo / that will direct the steps of transformations in the process of architectural production. Within this framework, the investigation is concerned with the production of a flexible, unstable and indeterminant building, focused on the concepts of &lsquo / transformation of space&rsquo / and &lsquo / constant change&rsquo / , that could be re-designed and re-generated in respect to possible future transformations in the program. Thus, architectural production is defined merely as a &lsquo / step&rsquo / or a &lsquo / snap-shot&rsquo / , controlled by the design tools suggesting the solutions for an ever-lasting transformation as the conditions change.

Cohomologia e propriedades estocásticas de transformações expansoras e observáveis lipschitzianos / Cohomology and stochastics properties of expanding maps and lipschitzians observables

Amanda de Lima 20 March 2007 (has links)
Provamos o Teorema do Limite Central para transformações expansoras por pedaços em um intervalo e observáveis com variação limitada. Utilizamos a abordagem desenvolvida por R. Rousseau-Egele, como apresentada por A. Broise. O método da demonstração se baseia no estudo de pertubações do operador de transferência de Ruelle-Perron-Frobenius. Uma contribuição original é dada no último capítulo, onde provamos que, para transformações markovianas expansoras, todos os observáveis não constantes, contínuos e com variação limitada não são infinitamente cohomólogos à zero, generalizando um resultado de Bamón, Rivera-Letelier, Urzúa and Kiwi para observáveis lipschitzianos e transformações \'z POT. n\' . A demonstração se baseia na teoria dos operadores de Ruelle-Perron-Frobenius desenvolvida nos capítulos anteriores / We prove the Central Limit Theorem for piecewise expanding interval transformations and observables with bounded variation, using the approach of J.Rousseau-Egele as described by A. Broise. This approach makes use of pertubations of the so-called Ruelle-Perron-Frobenius transfer operator. An original contribution is given in the last chapter, where we prove that for Markovian expanding interval maps all observables which are non constant, continuous and have bounded variation are not infinitely cohomologous with zero, generalizing a result by Bamón, Rivera-Letelier, Urzúa and Kiwi for Lipschitzian observables and the transformations \'z POT. n\' . Our demosntration uses the theory of Ruelle-Perron-Frobenius operators developed in the previos chapters

Transversal families of piecewise expanding maps / Famílias transversais de transformações expansoras por pedaços

Amanda de Lima 07 May 2015 (has links)
Let t:[a,b] → ft be a C2 family of \"good\" C4 e piecewise expanding unimodal maps, with a critical point c, that is transversal to the topological classes of such maps. Given a lipchitzian observable ∅, consider the function ℛ∅(t)=∫∅dµt, where µt is the unique bsolutely continuous invariant probability of ft. We show a central limit theorem for the modulus of continuity of ℝ∅, that is limh→0m{t ∈ [a,b] : t + h ∈ [a,b] e 1/(Ψ(t)(-log|h|)½)((ℛ∅(t + h) - ℛ∅(t))/h) ≤ y} converges to 1/(2π)½ ∫y-∞e-s2/2ds. Now, let us consider a C2+ε expanding map f : 𝕊1 → 𝕊1 and a C1+ε periodic function v : 𝕊1 → ℝ. We show that the unique bounded solution of the twisted cohomological equation v(x) = α(f(x)) - Df(x)α(x) is either of class C1+ε or nowhere differentiable. We also prove that if α is nowhere differentiable, them the modulus of continuity of α satisfies a central limit theorem, that is, there is α &gt 0 such that limh→0µ{x : (α(x + h) - α(x))/(σ𝓁h(-log|h|)½) ≤ y} = 1/(2π)½ ∫y-∞e-t2/2dt, where µ is the absolutely continuous invariant probability of f. / Seja t:[a,b] → ft uma família C2 \"boa\" de transformações unimodais expansoras por pedaços com um ponto crítico c, que é transversal às classes topológicas de tais transformações. Dado um observável lipschitziano ∅, considere a função ℛ∅(t)=∫∅dµt, onde µt é a única probabiidade invariante absolutamente contínua de ft. Mostramos um teorema do limite central para o módulo de continuidade de ℝ∅, isto é limh→0m{t ∈ [a,b] : t + h ∈ [a,b] e 1/(Ψ(t)(-log|h|)½)((ℛ∅(t + h) - ℛ∅(t))/h) ≤ y} converge para 1/(2π)½ ∫y-∞e-s2/2ds. Vamos considerar agora f : 𝕊1 → 𝕊1 uma transformação expansora de classe C2+ε e v : 𝕊1 → ℝ uma função periódica de classe C1+ε. Mostramos que a única solução limitada da equação cohomológica torcida v(x) = α(f(x)) - Df(x)α(x) ou é de classe C1+ε ou não possui derivada em ponto algum. Mostramos também que se α não possui derivada em ponto algum, então o módulo de continuidade de α satisfaz um teorema do limite central, isto é, existe α &gt 0 tal que limh→0µ{x : (α(x + h) - α(x))/(σ𝓁h(-log|h|)½) ≤ y} = 1/(2π)½ ∫y-∞e-t2/2dt, onde µ é a probabilidade invariante absolutamente contínua associada a f.

Usability concerns in GIS development for a wider user-base : A qualitative usability research in Swedish municipal infrastructure

Svanberg, Daniel, Winkvist, Fredrik January 2008 (has links)
We now live in a society where communicating is done mostly through computer-technology based mediums. In Swedish municipal infrastructure a lot of the communication-data consists of geospatial data-collections. This data is generated with Geographical Information Systems (GIS) which usage in Sweden has increased rapidly. This has lead to a competition between developers in designing their systems for a wider user-base. A transition between designs that has its focus on a small target group and designs intended for a wide range of different users puts the developers in a challenge where usability is one of the big concerns. In this thesis we, have adopted a qualitative research approach with contextual observations and usability testing, in order to identify the crucial usability concerns when designing GIS for a wider user-base. Results show that the most crucial usability concerns are related to system feedback and the GIS not being compatible with other GIS data formats. The research has been concentrated within municipalities in Sweden and results presented in this thesis are rough, but true indications. More research is needed to get detailed accuracy of the usability concerns. We hope that this thesis will aid developers of GIS in their design-phase and to be part of a foundation to future GIS-standards.
