Företag har olika sätt att se på kundrelationer och de marknader där de är verksamma. De har olika prioriteringar beroende på använd strategi och skillnader bör därför finnas i företagens arbete i stort, så också i marknadsföringsarbetet. Denna uppsats ämnar att undersöka och bidra med kunskap om dessa skillnader med utgångspunkt i de strategiska inriktningarna Low-Cost Defenders och Differentiated Defenders. Det genom en kvantitativ undersökning av nordeuropeiska företags procentuella användning av diverse mediekanaler. Även om tidigare forskning lyft relaterade frågor saknas forskning om hur mediekanalerna används av företagen som applicerar dessa två företagsstrategier. Resultaten av uppsatsen ger en förståelse för de två strategiernas användning av mediekanalerna och lyfter även möjliga förklaringar till varför företag väljer att använda sig av vissa metoder för att nå ut till sina valda målgrupper. Resultaten visar vissa likheter mellan företagen inom vardera strategi. En statistisk signifikant skillnad fanns emellertid mellan de två företagsstrategierna inom mediekanalerna TV och OOH (Out of Home). Här verkar de största olikheterna finnas mellan Low-Cost Defenders och Differentiated Defenders arbete med mediekanaler.

Little is known about the relative influence of age-differentiated leadership on healthy aging at work. Likewise, the age-conditional influence of age-differentiated leadership is understudied, and especially so in the context of the COVID-19 pandemic. Using a three-wave longitudinal study, we examined the role that age-differentiated leadership plays in the prediction of work ability, as measured three times over six months (n = 1130) during the early stages of the COVID-19 pandemic in Germany (i.e., December 2019, March 2020, and June 2020). The results suggest that although there were no systematic changes in work ability on average, there was notable within-person variability in work ability over time. Additionally, we find that a balanced approach to age-differentiated leadership that considers the needs of both older and younger employees matters most and complements the positive influence of leader–member exchange for predicting within-person variability in work ability. We also find that older employees’ work ability benefits from an approach to age-differentiated leadership that considers older employee’s needs, whereas younger employees’ work ability especially benefits from leader–member exchange and a balanced approach to age-differentiated leadership. Overall, these results provide initial support for the idea that an age-differentiated approach to leadership is important when considering healthy aging at work.

A large part of the empirical work on differentiated products markets has focused on demand estimation and the pricing behavior of firms. These two themes are key inputs in important applications such as the merging of two firms or the introduction of new products. The validity of inferences, therefore, depends on accurate demand estimates and sound assumptions about the pricing behavior of firms. This dissertation makes a contribution to this literature in two ways. First, it adds to previous techniques of estimating demand for differentiated products. Second, it extends previous analyses of pricing behavior to models of price leadership that, while important, have received limited attention. The investigation focuses on the U.S. brewing industry, where price leadership appears to be an important type of firm behavior. The analysis is conducted in two stages. In the first stage, the recent Distance Metric (DM) method devised by Pinkse, Slade and Brett is used to estimate the demand for 64 brands of beer in 58 major metropolitan areas of the United States. This study adds to previous applications of the DM method (Pinkse and Slade; Slade 2004) by employing a demand specification that is more flexible and also by estimating advertising substitution coefficients for numerous beer brands. In the second stage, different pricing models are compared and ranked by exploiting the exogenous change in the federal excise tax of 1991. Demand estimates of the first stage are used to compute the implied marginal costs for the different models of pricing behavior prior to the tax increase. Then, the tax increase is added to the these pre-tax increase marginal costs, and equilibrium prices for all brands are simulated for each model of pricing behavior. These "predicted" prices are then compared to actual prices for model assessment. Results indicate that Bertrand-Nash predicts the pricing behavior of firms more closely than other models, although Stackelberg leadership yields results that are not substanitally different from the Bertrand-Nash model. Nevertheless, Bertrand-Nash tends to under-predict prices of more price-elastic brands and to over-predict prices of less price- elastic brands. An implication of this result is that Anheuser-Busch could exert more market power by increasing the price of its highly inelastic brands, especially Budweiser. Overall, actual price movements as a result of the tax increase tend to be more similar across brands than predicted by any of the models considered. While this pattern is not inconsistent with leadership behavior, leadership models considered in this dissertation do not conform with this pattern. / Ph. D.

The security of a radio system hinges on its ability to effectively authenticate a user. This work proposes a two-factor authentication scheme using a token and a biometric. The users' access rights are determined during authentication and the users are served only those channels of data that they are privileged to receive. The strengths and the weaknesses of the implementation in reconfigurable hardware are identified. The capabilities of the scheme are put into perspective by comparing it to a high-end authentication system and by evaluating the use of standardized APIs and low-end authentication devices. Modifications to the system are suggested to improve the level of security the scheme provides. Finally, a baseline study is carried out to measure the data processing performance of a radio developed in reconfigurable hardware, which uses the proposed authentication scheme. / Master of Science

Throughout the history of Catholic schools in Los Angeles, the mission of Catholic schools and the Archdiocese governing its schools has been clear: Catholic schools must strive to serve children with varied learning needs. However, despite calls for inclusion from the Vatican, the United States Conference of Catholic Bishops, and efforts from trained administrators and professionals to help facilitate inclusion in schools, Catholic inclusive programs are not able to include all learners. Using qualitative research with semi-structured interviews, focus group, and document review, this study uses the framework of ableism and disability studies to research and analyze the two questions regarding inclusive practices in one Catholic elementary school that has had a program running for five years. The research questions are as follows: 1) What are St. Mary teachers’ beliefs, experiences, and perceptions about disability and inclusive education? 2) What do St. Mary teachers and administrators think are the best ways to foster acceptance of inclusive education in the school? Despite the fact that Catholic educators recognize that Catholic schools, as a matter of social justice, should be teaching all children, it is challenging and frustrating for them. Due to a lack of resources and support, limited exposure and experience of people with disabilities, and technical special education training, even the most dedicated, talented, and sympathetic Catholic educators wanting to serve children with special needs have difficulty doing so. Reasons relating to inconsistent teacher training, beliefs and experiences that students with special needs are “trouble,” limited resources, and teachers’ perceptions of fairness, time, and equity, all contribute to teachers’ frustration and limitations when including learners with special needs in their classrooms. The significance of this research study lies in documenting a Catholic school’s experience of developing, evolving, and establishing a working model of an inclusion program in one Los Angeles Catholic elementary school. To this end, this study provides larger contextual data to those in similar Catholic school settings across America about Catholic teacher training and the implementation of inclusive practices in Catholic schools. Also, this study hopes to further the discussion in the field of Catholic education about the right(s) of all Catholic children, regardless of ability, to a Catholic education, since, according to the Vatican, that it is a matter of human dignity that they receive a spiritual and emotional education as well as one that is appropriately academic.

The outcome of the project is a current trend of equal children education. The trend of inclusion leads to associate students with special needs with non-disabled students. It makes bigger demands on competence of teacher (the teacher on first level of education on elementary school in Czech Republic). The teacher who's applying this project must find the best way how to organize school lessons in heterogeneous classes. The teacher should be able to use entire potential of pupils since the school year has started. The theoretic part of book contains facts and advantages of differentiated instruction - these points were summed up from scientific literature sources. The author gives examples of teaching methods and their utilization. There are chapters dealing with school and family cooperation in the project, this part has very important impact on realizing the inclusion. The cooperation is also important to fulfil individual children needs. The author puts emphasis particularly on 'special education'(the needs of certain groups like socially weak students, Romany students or extraordinary gifted students). The theoretic issues are applied in practical part of book. There's an example of teaching plan, which she used in her class. The plan reveals the main points confronted in everyday reality. At...

A large school district in the northeastern United States struggled with teaching middle school English Language Learners (ELLs) to succeed in reading and writing. The purpose of this qualitative study was to investigate teachers' perceptions regarding what they could do to increase academic achievement for ELLs. The conceptual framework emerged from Weimer's learning-centered teaching, which aligns with Dewey's social constructivism. Ten purposefully sampled teachers agreed to be interviewed in the attempt to answer the research questions about instructional strategies teachers believed were best to deliver culturally and linguistically appropriate instruction for ELLs and what teachers believed could be done to improve ELLs' classroom engagement and motivation for increased academic achievement. Analysis and open, thematic coding of semi-structured interviews, classroom observations, and teachers' lesson plans were used to create seven themes, including differentiated instruction, background knowledge, challenges and difficulties, home-school connection, technology for diverse learners, administration and faculty collaboration, and professional development. Findings included participants' desire for meaningful professional development where differentiated instruction is modeled to address the cultural and linguistic needs of ELLs. The project was created to deliver this training for all teachers at the site, focusing on culturally and linguistically differentiated instruction, sheltered instruction, and collaborative learning. The findings and project may promote positive social change by improving instruction for culturally and linguistically diverse learners at the local site and similar school districts. Higher academic achievement would provide better opportunities for ELL students.
