Marketing Strategy of Digital Video Content Aggregators

Lee, Chi-Hung 28 July 2005 (has links)
The development of the information and communications technology has enabled digital contents to be aggregated for better customer services. The purpose of this thesis is to investigate whether different types of content aggregators have different marketing strategies. In this research, content aggregators in Taiwan are divided into two categories. Their market positioning and market-mix strategies are compared. Six companies with different market positions were investigated and the result indicates that they are different in many of their marketing strategies, including the breadth and depth of product lines, pricing strategies, content delivery channels, and promotion. Suggestions for their future improvement are discussed.

Percepción y aceptación de contenidos del libro Caminando de Nuevo 3 para la enseñanza de español

Pabon, Alexander January 2011 (has links)
This work presents an investigation done on the book Caminando de nuevo 3 that is adopted in some Swedish schools for the Spanish course they offer. The hypothesis explored whether the content of the book could create wrong stereotypes based on incorrect used of didactic content.Other related worked in line with this investigation were investigated. Furthermore, twenty students that had used this book were surveyed. The data collected was analyzed. This analysis is in line with the hypothesis of this work. A great majority of the students reported not to be motivated, they were not particularly enthusiastic toward the book, and were surprised by the content of the book related to the exercises, the text itself and the pictures used in the book.In conclusion this work suggests that this type of textbooks should be revised and present a better alternative for its text, visual and grammatical content.Finally, some recommendations are given both to teachers and students in order to reach the goals that have been defined by their curriculum.

Challenging cultural identities : Between new forms of tourism and old European cities

Wagenaar, Wester January 2016 (has links)
New forms of tourism are on the rise where the incentive to travel is not primarily induced by a country’s heritage, but by mediatized narratives, characters and locations starring in products such as movies, comics and literature. This so-called contents tourism is considered promising by some, but the question is: who benefits? Europe is often understood as the old continent, a place with a rich history. Modern products capitalize on this sense of oldness and tell new narratives, providing Europe with new identities. These differing identities create challenges for cities and therefore demand to be mitigated. Utilizing the Japanese concept of contents tourism, this thesis aims to shed a light on the impact of these forms of tourism on city identities. This provides a better understanding on how interests, and entwined identities, challenge one another in European cities. Three case studies are employed: Harry Potter tourism in Oxford, tourism induced by the Millennium series in Stockholm and Twilight tourism in the Italian city of Volterra. It argues that there are three ways in which a city can perceive identities brought about by contents tourism: acceptance, indifference or reluctance. Not all alternative identities are considered challenging, but contents tourism influences city identities regardless.

A practical appraisal for pipeline inspection using guided waves of torsional mode

Li, Bing-Hung 13 August 2004 (has links)
Abstract This thesis studies the practical appraisal for pipeline inspection using the guided wave T(0,1) mode. The characteristic of reflected signals from the features of pipeline for various coated materials and fluid-filled pipes are also evaluated. The attenuation and the traveling distance of the guided wave are then calculated from the above-mentioned data for pipeline inspection in petro-chemical industries. In the experimental setup, the torsional mode is excited at one axial location using an array of transducers distributed around the circumference of the 6-inch test pipe. The reflected signals from various features, such as flanges, welds, supports, bends, defects and patches are analyzed at first at specific frequencies in the experiments. The effect of various coated material such as bitumen, PE and insulated material are also evaluated for the propagating torsional mode T(0,1) in the pipe. The results show that the attenuation of reflected signal is heavy for the bitumen-coated case because its viscosity is much higher than the other cases. Furthermore, the effect of pipe contents for defect detection using T(0,1) mode is investigated in this thesis. Various pipe contents, such as water, diesel oil, lubricant and fuel oil are deposit into the test pipe, respectively, to evaluate the influence to T(0,1). For the attenuation evaluation of reflected signal from flange in pipe, the reflected signal from an air-content pipe is measured for reference to compare with the measurements of other pipe contents in the experiments. The results show that the low viscosity liquid deposit in the pipe, such as water, diesel oil and lubricant, has no effect on the torsional mode; while the high viscous of the fuel oil deposit in the pipe attenuates the reflected signal heavily. It became evident that the torsional mode T(0,1) is most suitable for use in fluid-filled pipeline inspection.

Rocking Response of Slender Freestanding Building Contents in Fixed-Base and Base-Isolated Buildings

Linde, Scott A. 18 November 2016 (has links)
The primary seismic response mode of freestanding slender building contents is rocking. Rocking is one of the most damaging response modes due to large accelerations at impact and the possibility of toppling. This study investigates the rocking response of contents within fixed-base and base-isolated buildings so that better-informed decisions can be made, either at the design stage for new structures or during the performance evaluation for existing structures, to mitigate the effects of the destructive rocking behaviour and consequently minimize injury, economic loss, and downtime. A 3D model of a hospital building was created in OpenSees and analyzed to obtain floor accelerations for a suite of 20 broadband ground motions. These motions were then used as input to compute the rocking responses of many building contents. The rocking responses were compared and contrasted to determine the effect of the block’s size, slenderness, floor level, and placement within a level. The rocking response of contents in buildings isolated with lead plug and triple friction pendulum bearings were compared to the fixed-base building to determine the effectiveness of isolation as a means to control rocking. Fragility curves were also created for the fixed-base and isolated buildings. The vertical component of the floor accelerations had little effect on the rocking response of contents. The significance of this is that the location of an object on a given story does not affect its rocking response. However, higher vertical accelerations did increase the likelihood of the object lifting off the floor. The rocking response of stocky contents increased from one story to the next, but as the slenderness increased this transition became less evident. Base isolation was found to be effective at reducing both the likelihood to uplift and overturn. The longer period systems provided superior protection despite the long period pulse like motion while the damping of the systems had little effect on the rocking response. / Thesis / Master of Applied Science (MASc) / During an earthquake slender building contents respond by rocking about their edges. Rocking causes damage to sensitive and brittle objects as well as safety hazards if it results in the overturning of heavy objects. One goal of this study was to define the rocking response of rigid contents in a conventional braced frame hospital. In general, larger and stockier objects were less likely to overturn. Also, overturning was more prevalent higher up in the building while the location of an object within a given story had little effect. Another objective was to determine the effectiveness of base isolation, a technique that decouples the motion of the building from the ground using flexible bearings, as a strategy to protect contents that are vulnerable to rocking during an earthquake. This was found to be quite effective at reducing both the occurrence of uplift (the initiation of rocking) as well as toppling.

Life history of capelin (Mallotus Villosus (Müller, 1776)) and dietary overlap with Arctic cod (Boreogadus saida (Lepechin, 1774)) in the Canadian Arctic

McNicholl, Darcy, McNicholl, Darcy 27 November 2015 (has links)
Capelin (Mallotus villosus (Müller, 1776)) is an important marine forage fish species that typically inhabits sub-Arctic and temperate circumpolar waters. Capelin have recently been reported in greater abundance in Arctic regions, and are considered an indicator for warming climate in the northern marine ecosystem. The goal of this thesis is to examine intrinsic factors among capelin populations, and whether niche overlap among sympatric capelin and Arctic cod (Boreogadus saida (Lepechin, 1774)) will affect the abundance and persistence of capelin in the Arctic as temperatures continue to rise. Life history comparisons of capelin from two Arctic regions (Western Beaufort Sea, Cumberland Sound) relative to a sub-Arctic population (Newfoundland) show that body size, body condition, growth rate and age-at-maturity vary among these regions. Life history characteristics that are adapted to northern environments and increasing temperatures will allow the presence and persistence of this species to increase in the Arctic. The consequence of increased abundance of capelin in the Arctic environment could be competition between capelin and Arctic cod, an Arctic species within a similar dietary niche. Stomach contents indicated that both species feed primarily on calanoid copepods and this result was corroborated with high dietary overlap in isotopic bivariate space (carbon and nitrogen stable isotopes). The occurrence of capelin is expected to increase in the Arctic with rising temperatures, thus adaptation in life history traits in capelin specific to each region may facilitate increased abundance and persistence, and possibly contribute to competitive pressure on Arctic cod. Potential competition will be particularly important in nearshore and shelf habitats where shifts in availability of intermediate trophic level taxa will influence diet and distribution of key predators such as beluga, sea birds, and anadromous fishes. As the Arctic environment changes with climate shifts, newly adapted or dispersed species from sub-Arctic systems are expected to drive shifts in ecosystem structure and function in the marine environment. / October 2016
