"En stridsplan överlever sällan första stridskontakt" : Slaget om Darwin – Goose Green

Nilsson, Nicklas January 2009 (has links)
Den 26 maj 1982 påbörjas anfallet mot samhällena Darwin och Goose Green. Anfallande styrka är brittiska, 2 Paras, på plats och försvarsgrupperade är Taskforce Mercedes. Britterna vinner slutligen över en numerärt överlägsen och försvarsgrupperad argentinsk styrka. Hur kommer det sig att detta kan ske? Jag kommer, för att kunna besvara mina frågeställningar, i det här självständiga arbetet att med utgång i de grundläggande förmågorna, ledning, verkan, skydd, rörlighet, uthållighet och und/info, analysera slaget. Dessa frågeställningar är:  -          Vilken av de grundläggande förmågorna var avgörande för 2 Paras seger? -          Vilken av de grundläggande förmågorna var avgörande för Taskforce Mercedes förlust? Jag har kommit fram till följande; britterna kunde tack vare en kombination av förmågorna ledning och verkan avgöra striden till deras fördel. För argentinarna var det förmågan ledning som bäddade för deras förlust. Vill du veta hur jag kommit fram till detta och varför uppmanar jag dig att läsa detta arbete. / My name is Nicklas Nilsson. I’m a cadet studying at the Swedish Land warfare Centre. As a part of becoming a commissioned officer I’m obligated to write an essay at fundamental level. I have written about the Battle for Darwin – Goose Green. A battle between 2 Para and Taskforce Mercedes. I have used (de grundläggande förmågorna) six fundamental abilities as an analysis instrument. The questions I am going to answer with this essay are:  -What ability was decisive for 2 Para’s victory? -What ability was decisive for Taskforce Mercedes defeat?  Initially I will conduct a literature study, followed by a comparative case study. I have come to the following conclusions: The Argentines lost due to their lack of a good leadership and The British won due to the abilities, better trained, better motivated and with more experience. They also, contrary to the Argentines, had leaders that was present and tried to resolve the situations they’ve gotten in to. If you want to read more about this and how I’ve come to these conclusions, please read this essay.

Genre et société à Lima pendant la seconde moitié du XIXe siècle : analyse de l'oeuvre de Mercedes Cabello de Carbonera (1842-1909)

Cárdenas Moreno, Mónica 02 October 2013 (has links) (PDF)
Pendant la seconde moitié du XIXe siècle, Lima était une ville en train de se moderniser grâce à la richesse du guano. Dans les années 1870 émerge un groupe de femmes de lettres qui s'appuient sur la presse et les institutions littéraires. Elles trouvent des espaces ouverts à leur expression artistique et à leurs idées comme les Veladas Literarias. Après la Guerre du Pacifique (1879-1883), après l'occupation de la ville de Lima par l'armée chilienne, quelques intellectuels ont évolué vers une écriture plus critique de la société. Mercedes Cabello de Carbonera (1842-1909) est la première romancière au Pérou avec une production très importante. Elle construit ses romans à partir d'un regard sociologique sur la condition de la femme, car elle croit que de cela dépend la transformation morale de la société, et par conséquent le progrès.Nous développons notre recherche en trois parties. Dans la première, nous nous occupons du contexte politique, social et culturel et de l'éducation en particulier des femmes de lettres comme Cabello. Dans la deuxième partie, nous analysons les articles et les six romans de Cabello divisés en trois périodes (les romans traditionnels, les romans de la réécriture et les romans de la transgression) ; finalement, dans la dernière partie, nous établissons une comparaison avec d'autres femmes de lettres de l'époque : Soledad Acosta, Colombienne, et Emilia Pardo Bazán, pour distinguer la singularité du réalisme péruvien, et la représentation de la femme, par rapport à la production littéraire d'autres pays hispanophones.

UI Design Trends InAutomobile DigitalMedia Players : How Trends Compare To User Preference In Sweden

Kézy, Máté, Stendahl, Adam January 2022 (has links)
This study aims to evaluate the preferences of drivers in Sweden, in regard to incar digital media players. As interfaces in cars, to some extent, are taking over thefunctionality of physical buttons and knobs, it is increasingly important for carmanufacturers to better understand what their users prefer.Through an analysis of current trends and measurements of user preferences, wehave identified areas for improvement and further development of these mediaplayer interfaces. These suggested improvements are as follows: • Using the screen real estate for important items • Emphasizing important elements by more efficient use of spacing andsizing • Removing or hiding menu items that are used sparingly • Using the concept of familiarity to create more user-friendly interfaces

Pensamiento binario y dinámica social en El conspirador (Autobiografía de un hombre público), de Mercedes Cabello de Carbonera, y Julia o escenas de la vida en Lima, de Luis Benjamín Cisneros

Marchena Siverio, Eduardo 12 November 2018 (has links)
Buscamos, a partir del análisis del pensamiento binario en relación con la dinámica social en la Lima decimonónica, resaltar la importancia de la reafirmación de la idea de individualidad, más allá de toda diferenciación de género, como propuesta alternativa para regenerar una sociedad contradictoria y decadente, un tema que, a nuestro entender, merece una mayor atención y debate. Consideramos que las propuestas de El conspirador. Autobiografía de un hombre público (de Mercedes Cabello de Carbonera) y Julia o escenas de la vida en Lima (de Luis Benjamín Cisneros), más allá de toda crítica o defensa de determinados grupos sociales o identidades discursivas, apuntan a revalorizar el libre albedrío del individuo (fortalecer su individualidad en un entorno social nuevo), de modo que, lo que define y legitima al sujeto, más que su figura discursiva, es su voluntad y no se puede regenerar una sociedad a partir del discurso, sino trascendiendo a él. Nos proponemos examinar las paradojas en las figuras discursivas de masculinidad y feminidad a partir de la crítica social presente en los mencionados textos. Si bien las diferencias de género serán objeto de atención, nos enfocaremos en la tensión entre las aspiraciones del individuo y las exigencias de su sociedad (una sociedad a la que ese individuo critica a partir de un discurso propio con el que pretende autoconstruir su identidad). Para ello, optamos por un análisis comparativo orientado a un balance de continuidades y diferencias. Los discursos dicotómicos que se pretenden cerrados y absolutos, ya sean impuestos por el poder social o propuestos por un individuo inconforme, se muestran relativos e insuficientes al momento de generar identidades sólidas y claramente diferenciadas. Así, pese a sus diferencias, ambas novelas parecen apuntar a la revalorización del libre albedrío del individuo más allá de todo intento por fijar identidades discursivamente. / Tesis

La educación de las mujeres en dos novelas peruanas del siglo XIX : Herencia y Blanca Sol

Bustamante Oliva, Lita Giannina 21 March 2016 (has links)
Esta investigación describe la situación de la educación de las mujeres peruanas de la élite limeña a partir de la segunda mitad del siglo XIX. Analizando los aspectos educativos presentados en las novelas Herencia y Blanca Sol, de Clorinda Matto de Turner y Mercedes Cabello de Carbonera respectivamente, se explican e interpretan las características de la educación que se ofrecía a niñas y jóvenes en la capital del Perú. Por un lado, los colegios privados de la época presentaban tanto un currículo expreso y como un currículum oculto, de entre los cuales el último operaba con gran eficacia como respuesta a la falta de coherencia entre el discurso y la práctica educativa. En este sentido, se cuestiona si la educación brindada en los colegios católicos era la más adecuada para formar a las madres de los ciudadanos de la nueva república, así como para preparar a la mujer con la autonomía y criterio suficientes para autosostenerse, para dirigir su hogar y para vivir coherentemente de acuerdo a principios humanos y cristianos. Por otro lado, la educación en el hogar estaba bajo la responsabilidad de la madre de familia. Se esperaba que la mujer se condujera en todo según el ideal femenino católico de ángel del hogar y que, de acuerdo a dichos parámetros, educara a sus hijas. El análisis permite comprobar cómo la educación de las mujeres se desarrollaba de espaldas a la realidad, imitando modelos extranjeros y resultando de poca utilidad para responder a las exigencias de la vida en el Perú. Esto ocurría porque hasta ese momento la sociedad no llegaba a comprender todavía los aportes intelectuales acerca de la educación de la mujer presentados por las autoras de las novelas estudiadas en esta tesis, investigación que representa una oportunidad para hacer las revisiones y reflexiones pertinentes / This research describes women´s education in nineteenth century in Perú, focused on high society girls. It analyses educational topics in Herencia and Blanca Sol, novels written by Clorinda Matto de Turner and Mercedes Cabello de Carbonera. In these plays it is possible to see the way hidden curriculum was very strong in girls’ schools because of the incoherence between speech and practice. Aims of education are also analyzed considering women possibilities to live by themselves, to organize and manage their own homes by making responsible use of money or getting a good job. It is also questioned if that type of education was the best to afford the needs of the new republic and if it was in good path to educate the mothers of the future Peruvian citizens. / Tesis

Hydrophobicity and Composition-Dependent Anomalies in Aqueous Binary Mixtures, along with some Contribution to Diffusion on Rugged Energy Landscape

Banerjee, Saikat January 2014 (has links) (PDF)
I started writing this thesis not only to obtain a doctoral degree, but also to compile in a particular way all the work that I have done during this time. The articles published during these years can only give a short overview of my research task. I decided to give my own perspective of the things I have learned and the results I have obtained. Some sections are directly the published articles, but some other are not and contain a significant amount of unpublished data. Even in some cases the published plots have been modified / altered to provide more insight or to maintain consistency. Historical perspectives often provide a deep understanding of the problems and have been briefly discussed in some chapters. This thesis contains theoretical and computer simulation studies to under-stand effects of spatial correlation on dynamics in several complex systems. Based on the different phenomena studied, the thesis has been divided into three major parts: I. Pair hydrophobicity, composition-dependent anomalies and structural trans-formations in aqueous binary mixtures II. Microscopic analysis of hydrophobic force law in a two dimensional (2D) water-like model system III. Diffusion of a tagged particle on a rugged energy landscape with spatial correlations The three parts have been further divided into ten chapters. In the following we provide part-wise and chapter-wise outline of the thesis. Part I consists of six chapters, where we focus on several important aqueous binary mixtures of amphiphilic molecules. To start with, Chapter 1 provides an introduction to non-ideality often encountered in aqueous binary mixtures. Here we briefly discuss the existing ideas of structural transformations associated with solvation of a foreign molecule in water, with particular emphasis on the classic “iceberg” model. Over the last decade, several investigations, especially neutron scattering and diffraction experiments, have questioned the validity of existing theories and have given rise to an alternate molecular picture involving micro aggregation of amphiphilic co-solvents in their aqueous binary mixtures. Such microheterogeneity was also supported by other experiments and simulations. In Chapter 2, we present our calculation of the separation dependence of potential of mean force (PMF) between two methane molecules in water-dimethyl sulfoxide (DMSO) mixture, using constrained molecular dynamics simulation. It helps us to understand the composition-dependence of pair hydrophobicity in this binary solvent. We find that pair hydrophobicity in the medium is surprisingly enhanced at DMSO mole fraction xDMSO ≈ 0.15, which explains several anomalous properties of this binary mixture – including the age-old mystery of DMSO being a protein stabilizer at lower concentration and protein destabilizer at higher concentration. Chapter 3 starts with discussion of non-monotonic composition dependence of several other properties in water-DMSO binary mixture, like diffusion coefficient, local composition fluctuation and fluctuations in total dipole moment of the system. All these properties exhibit weak to strong anomalies at low solute concentration. We attempt to provide a physical interpretation of such anomalies. Previous analyses often suggested occurrence of a “structural transformation” (or, microheterogeneity) in aqueous binary mixtures of amphiphilic molecules. We show that this structural transformation can be characterized and better understood under the purview of percolation theory. We define the self-aggregates of DMSO as clusters. Analysis of fractal dimension and cluster size distribution with reference to corresponding “universal” scaling exponents, combined with calculation of weight-averaged fraction of largest cluster and cluster size weight average, reveal a percolation transition of the clusters of DMSO in the anomalous concentration range. The percolation threshold appears at xDMSO ≈ 0.15. The molecular picture suggests that DMSO molecules form segregated islands or micro-aggregates at concentrations below the percolation threshold. Close to the critical concentration, DMSO molecules start forming a spanning cluster which gives rise to a bi-continuous phase (of water-rich region and DMSO-rich region) beyond the threshold of xDMSO ≈ 0.15. This percolation transition might be responsible for composition-dependent anomalies of the binary mixture in this low concentration regime. Similar phenomenon is observed for another amphiphilic molecule – ethanol, as discussed in Chapter 4. We again find composition dependent anomalies in several thermophysical properties, such as local composition fluctuation, radial distribution function of ethyl groups and self-diffusion co-efficient of ethanol. Earlier experiments often suggested distinct structural regimes in water-ethanol mixture at different concentrations. Using the statistical mechanical techniques introduced in the previous chapter, we show that ethanol clusters undergo a percolation transition in the anomalous concentration range. Despite the lack of a precise determination of the percolation threshold, estimate lies in the ethanol mole fraction range xEtOH ≈ 0.075 - 0.10. This difficulty is probably due to transient nature of the clusters (as will be discussed in Chapter 6) and finite size of the system. The scaling of ethanol cluster size distribution and the fractal behavior of ethanol clusters, however, conclusively demonstrate their “spanning” nature. To develop a unified understanding, we further study the composition-dependent anomalies and structural transformations in another amphiphilic molecule, tertiary butyl alcohol (TBA) in Chapter 5. Similar to the above-mentioned aqueous binary mixtures of DMSO and ethanol, we demonstrate here that the anomalies occur due to local structural changes involving self-aggregation of TBA molecules and percolation transition of TBA clusters at xTBA ≈ 0.05. At this percolation threshold, we observe a lambda-type divergence in the fluctuation of the size of the largest TBA cluster, reminiscent of a critical point. Interestingly, water molecules themselves exhibit a reverse percolation transition at higher TBA concentration ≈ 0.45, where large spanning water clusters now break-up into small clusters. This is accompanied by significant divergence of the fluctuations in the size of the largest water cluster. This second transition gives rise to another set of anomalies around. We conclude this part of the thesis with Chapter 6, where we introduce a novel method for understanding the stability of fluctuating clusters of DMSO, ethanol and TBA in their respective aqueous binary mixtures. We find that TBA clusters are the most stable, whereas ethanol clusters are the most transient among the three representative amphiphilic co-solvents. This correlates well with the amplitude of anomalies observed in these three binary mixtures. Part II deals with the topic of hydrophobic force law in water. In the introductory Chapter 7 of this part, we briefly discuss the concept of hydrophobicity which is believed to be of importance in understanding / explaining the initial processes involved in protein folding. We also discuss the experimental observations of Israelachvili (on the force between hydrophobic plates) and the empirical hydrophobic force law. We briefly touch upon the theoretical back-ground, including Lum-Chandler-Weeks theory. We conclude this chapter with a brief account of relevant and important in silico studies so far. In Chapter 8, we present our studies on Mercedes-Benz (MB) model – a two dimensional model system where circular disks interact with an anisotropic potential. This model was introduced by Ben-Naim and was later parametrized by Dill and co-workers to reproduce many of the anomalous properties of water. Using molecular dynamics simulation, we show that hydrophobic force law is indeed observed in MB model, with a correlation length of ξ=3.79. The simplicity of the model enables us to unravel the underlying physics that leads to this long range force between hydrophobic plates. In accordance with Lum-Chandler-Weeks theory, density fluctuation of MB particles (leading to cavitation) between the hydrophobic rods is clearly distinguishable – but it is not sufficiently long ranged, with density correlation extending only up to ζ=2.45. We find that relative orientation of MB molecules plays an important role in the origin of the hydrophobic force in long range. We define appropriate order parameters to capture the role of orientation, and briefly discuss a plausible approach of an orientation-dependent theory to explain this phenomenon. Part III consists of two chapters and focuses on the diffusion of a Brownian particle on a Gaussian random energy landscape. We articulate the rich history of the problem in the introductory Chapter 9. Despite broad applicability and historical importance of the problem, we have little knowledge about the effect of ruggedness on diffusion at a quantitative level. Every study seems to use the expression of Zwanzig [Proc. Natl. Acad. U.S.A, 85, 2029 (1988)] who derived the effective diffusion coefficient, Deff =D0 exp (-β2ε2 )for a Gaussian random surface with variance ε, but validity of the same has never been tested rigorously. In Chapter 10, we introduce two models of Gaussian random energy surface – a discrete lattice and a continuous field. Using computer simulation and theoretical analyses, we explore many different aspects of the diffusion process. We show that the elegant expression of Zwanzig can be reproduced ex-actly by Rosenfeld diffusion-entropy scaling relationship. Our simulations show that Zwanzig’s expression overestimates diffusion in the uncorrelated Gaussian random lattice – differing even by more than an order of magnitude at moderately high ruggedness (ε>3.0). The disparity originates from the presence of “three-site traps” (TST) on the landscape – which are formed by deep minima flanked by high barriers on either side. Using mean first passage time (MFPT) formalism, we derive an expression for the effective diffusion coefficient, Deff =D0 exp ( -β2ε2)[1 +erf (βε/2)]−1 in the presence of TSTs. This modified expression reproduces the simulation results accurately. Further, in presence of spatial correlation we derive a general expression, which reduces to Zwanzig’s form in the limit of infinite spatial correlation and to the above-mentioned equation in absence of correlation. The Gaussian random field has an inherent spatial correlation. Diffusion coefficient obtained from the Gaussian field – both by simulations and analytical methods – establish the effect of spatial correlation on random walk. We make special note of the fact that presence of TSTs at large ruggedness gives rise to an apparent breakdown of ergodicity of the type often encountered in glassy liquids. We characterize the same using non-Gaussian order parameter, and show that this “breakdown” scales with ruggedness following an asymptotic power law. We have discussed the scope of future work at the end of each chapter when-ever appropriate.

An evaluation of the brand campus concept implemented at Mercedes-Benz South Africa: a case study

Samkange, Tichaona January 2009 (has links)
Primarily, this research study was concerned with the evaluation of the brand campus concept implemented at then DaimlerChrysler South Africa in 2002, as a case study. Pretoria-based Mercedes-Benz South Africa (Pty) Ltd. (MBSA) is a subsidiary of global vehicle manufacturer Germany’s Daimler-Benz AG (DBAG). They are responsible for assembling, distributing and retailing, certain Mercedes-Benz and Mitsubishi vehicle brands, and spare parts. The landmark 1998 DaimlerChrysler global ‘merger of equals’ was preceded by the 1995 joint venture between Mercedes-Benz and Mitsubishi Motor Corporation. Consequently, three brands (Mercedes-Benz, Chrysler and Mitsubishi) were retailed and marketed under DaimlerChrysler South Africa (Pty) Ltd. (DCSA), positioned next to each other in the same showroom. This report identifies key challenges stemming from this approach, namely: brand strength dilution, more than 80 multi-franchised dealers and multi-branded showrooms, service capacity problems, old working environment and infrastructure, and perceived intra-brand competition. The research evidence suggests that these problems prompted then DCSA to launch the 2000 Dealer Network Strategy (DNS). In the grand scheme of things, the DNS intervention entailed partitioning the dealer network into five brand centres in five metro regions, and eighteen market centres in the rural areas. The brand campus concept was borne out of DNS and proved to be a masterstroke since, the primary focus was on streamlining the retail facilities for DCSA vehicle sales, service and spare parts for both the passenger and commercial vehicles. This study highlights key pillars of the brand campus concept, namely: profitability, brand focus, customer orientation and diversity. The challenge was to address seven major drivers of the brand campus concept, namely: after-sales vehicle support, vehicle service capacity, lead-times, spare parts availability, sales information propagation, behavior of sales personnel and the overall vehicle dealership appearance. Semi-structured interviews constituted part of the evaluation based on the perspectives of five customers, three dealer principals and two MBSA marketing executives. The research evidence, which also came from MBSA documentation and direct observation, shows that this innovative concept has been remarkably successful.
