Testing the Pub Principle: A Look at Push and Pull Communication on Facebook

Page, Tyler Grant 01 June 2015 (has links)
This research tests the value of push and pull communication on Facebook in the first effort to test the validity of the Pub Principle and Social Intrusion Theory. This theory explains how audiences engage in a tug-of-war with commercial forces during mass communication and that commercial messaging is ultimately dependent upon the acceptance or rejection of its intended audience. The pub principle explains that social media is unlike traditional mass media and that the rules commercial forces must play by are different than for other mass media. Using a mixed-method approach, this research confirms the validity of this principle and theory. It finds that Facebook users spend significantly less time looking at push content like paid advertisements than at pull content like fan pages. This research also shows that audiences prefer dealing with pull content over push content on Facebook. The Pub Principle and Social Intrusion Theory are therefore supported by this research.

Perceptions of International Teacher Turnover in East Asia Regional Council of Schools

Tkachyk, Leon Michael 01 January 2017 (has links)
High teacher turnover has become a serious problem globally, in many international schools, and is a growing concern in segments of the East Asia Regional Council of Schools (EARCOS). This persistent problem has a detrimental effect on student learning and upsets the culture of school communities. Herzberg's motivation-hygiene theory served as the framework for this qualitative case study research that examined the perceptions of EARCOS international overseas-hire teachers, to determine their beliefs regarding high teacher turnover in international schools. These questions gave direction to this study: What factors do international teachers in EARCOS member schools believe contribute to high teacher turnover in international schools? What do international teachers in EARCOS member schools believe is the result of high teacher turnover in international schools? What steps do international teachers in EARCOS member schools believe should be taken to reduce high turnover in international schools? Purposeful homogenous sampling was used to identify 8 focus group interview participants from the entire pre-K-12 international overseas-hire teacher population from the 149 EARCOS member schools. Coded data were examined, analyzed, and categorized into themes related to Herzberg's motivation-hygiene theory. Member checking, peer debriefing, and external auditing were used to add validity to the research study. The analysis of the data and findings revealed that lack of effective mentorship, lack of administrative leadership support, and ineffective systems are the major contributors to international teacher turnover in international schools. A white paper was developed and constructed from the themes that emerged from this study and presented to EARCOS member school administrators, to potentially use to address the issue of increasing international overseas-hire teacher turnover rates in international schools. This acquired knowledge could lead to positive social change that can influence the practices, structural procedures, and policies of EARCOS and other international school systems related to teacher turnover.

Evaluation of Semiochemical Strategies for the Protection of Whitebark Pine Stands Against Mountain Pine Beetle Attack Within the Greater Yellowstone Ecosystem

Schen-Langenheim, Greta Katherine 01 May 2010 (has links)
High-dose verbenone, verbenone plus nonhost volatiles (NHVs), and both semiochemicals in combination with aggregant-baited funnel traps were tested for stand- level protection against mountain pine beetle attack for two consecutive years (2004-2005) at three seral high elevation whitebark pine sites in the Greater Yellowstone Ecosystem. In 2004, two 0.25-hectare treatments comprised of 25 high-dose verbenone pouches or verbenone pouches combined with single baited funnel traps were tested in a push-pull strategy. In 2005, 25 high-dose verbenone and 25 NHV pouches, or verbenone and NHV in combination with baited funnel trap clusters were tested. In both years, treatments were compared to 0.25-hectare control plots with no semiochemicals or funnel traps. The proportion of trees attacked by mountain pine beetle in treated plots was significantly reduced, when compared to control plots, at only one site treated with verbenone in 2004, and at only one site in 2005. High-dose verbenone alone, verbenone and NHVs, and both semiochemicals combined with baited funnel traps in a push-pull strategy did not consistently reduce the proportion of mountain pine beetle attacked trees relative to control plots. No covariates tested, including stand density, beetle population size, or tree size were consistently significant in explaining proportion of trees attacked.

Seismic fragility and retrofitting for a reinforced concrete flat-slab structure

Bai, Jong-Wha 30 September 2004 (has links)
The effectiveness of seismic retrofitting applied to enhance seismic performance was assessed for a five-story reinforced concrete (RC) flat-slab building structure in the central United States. In addition to this, an assessment of seismic fragility that relates the probability of exceeding a performance level to the earthquake intensity was conducted. The response of the structure was predicted using nonlinear static and dynamic analyses with synthetic ground motion records for the central U.S. region. In addition, two analytical approaches for nonlinear response analysis were compared. FEMA 356 (ASCE 2000) criteria were used to evaluate the seismic performance of the case study building. Two approaches of FEMA 356 were used for seismic evaluation: global-level and member-level using three performance levels (Immediate Occupancy, Life Safety and Collapse Prevention). In addition to these limit states, punching shear drift limits were also considered to establish an upper bound drift capacity limit for collapse prevention. Based on the seismic evaluation results, three possible retrofit techniques were applied to improve the seismic performance of the structure, including addition of shear walls, addition of RC column jackets, and confinement of the column plastic hinge zones using externally bonded steel plates. Finally, fragility relationships were developed for the existing and retrofitted structure using several performance levels. Fragility curves for the retrofitted structure were compared with those for the unretrofitted structure. For various performance levels to assess the fragility curves, FEMA global drift limits were compared with the drift limits based on the FEMA member-level criteria. In addition to this, performance levels which were based on additional quantitative limits were also considered and compared with FEMA drift limits.

From monopoly to private pharmacies : Buy-out and franchising: Finding the entrepreneur within the pharmacist

Bergqvist, Jimmy, Wolf, Henrik, Stigson, Gustav January 2009 (has links)
One of Sweden’s most well known monopolies is approaching its end, Apoteket AB. A re-regulation of a state owned monopoly is nothing new but it happens within an interesting trade. Since the government is in total control of the whole re-regulation process, we found it interesting to see how they managed to include the potential individuals who want to take over a pharmacy. After all, many are the times the government has emphasized the importance of small firms. Out of the approximately 900 pharmacies owned by Apoteket AB, 150 are going to be sold to individuals. This group is called “small enterprise cluster”, and this cluster became the focus of our thesis. We wanted to get an insight into this group, since it is more complex and diverse compared to the large corporations entering the market. Purpose The purpose of this thesis is to measure the willingness to take over pharmacies among the employees of Apoteket AB, as well as to analyse how the government's support has affected the decisions of individuals. Method In order to get a good view of the re-regulation process we chose a qualitative approach, where we performed personal interviews with 6 respondents equally spread out on 3 pharmacies in a medium sized Swedish city and the surrounding area. The interviews where performed in a semi-structured manner. Besides the primary data, secondary data was collected. It builds the foundation for the theoretical framework and the analysis of the interviews. Since the theoretical framework was created before the research was performed, the study used a deductive research approach.

Social media marketing : How does your company interact with customers?

Granholm, Madelene, Windh, Sofie January 2011 (has links)
The purpose of this thesis was to gain an understanding of how the use of social media can build customer relationships and how interactions in these communication channels can be managed and optimized. A qualitative and deductive method was chosen for a deeper, more detailed and descriptive explanation of the considered topic. Three case studies have been implemented since this method was optimal to the purpose. Creating customer relationships through social media demands an understanding from a company perspective regarding how to treat customers well, encourage interactions and offer valued information. There are challenges working with social media and it is essential to consider the risks because the word-of-web can spread quickly.

Coordination: key to development : Field study about rural livelihoods in Ribáuè and the impact of coordination failure

Banning, Christophe, Dalarud Lidén, Erik January 2012 (has links)
This Master thesis is the result of a study in which we looked at people's livelihoods - through the sustainable rural livelihoods analytical framework - from a coordination failure perspective. During three weeks spent in the district of Ribáuè, Mozambique, enabled us to conduct interviews with people from many different social categories and understand the conditions in which small-scale farmers live. The paper tackles issues related to development in general and governmental intervention and contributes to the debate about the type of growth which is on-going in Mozambique. What are the coordination failures that impact people's livelihoods in Mozambique, a country where strong economic growth does not seem to help the poorest to get out of poverty. / The Mozambican economy is characterised by a high level of employment in the agricultural sector. Most farmers are small-scale and farm for subsistence. As development at global level will continue to pressure these farmers to increase their productivity, the question is to know how this will affect the small-scale farmers’ capacity to improve their livelihoods. The economy of the African continent is predicted to rise substantially and countries like Mozambiquehave been praised for their staggering economic growth. However despite growth, the situation remains unchanged for many small-scale farmers. The intention of this research is then to look into the conditions in which small-scale agricultural activities take place. This study was carried out is the district of Ribáuè, located in the northern provinceof Nampula, Mozambique and adopts an abductive approach as it investigates coordination failures around farming activities. In other words, aspects concerning agricultural activities that are difficult to observe, will be included. The starting point for this argument is that it is impossible to obtain sustainable development (i.e. including small-scale farmers) without taking a holistic approach. Through this study, it becomes clear that small-scale farmers face a variety of obstacles from which patterns can be extracted. Strong emphasis is put on the importance of surrounding factors such as infrastructures, access to credit, wage work opportunities, access to inputs, extension services, and market access.  All these factors impact people’s livelihoods; and by investing in all of them in a coordinated way, it creates synergetic effects and boosts the potential for further development of each feature. This inter-connectivity becomes clear when considering that wage work opportunities are created when investments are made in the rehabilitation of infrastructures or the expansion of extension services. Furthermore, market access increases when the connectivity of remote farmers is improved and their livelihoods develop when their surplus can be sold. The amount of surplus farmers have is in turn affected by their financial capital, access to inputs, and access to extension services. Singling out one of these features as more important than the others risks missing the point and hindering sustainable development. This calls for big versatile government investments, in the form of big push policies, to ensure that these areas inter-connect and to create the highest possible levels of synergy.

The Rural Labor and Urbanization in Mainland China

Lin, Ching-Hao 23 June 2008 (has links)
Labor mobility in the rural area of Mainland China plays recently an important role in its economic development process. And this enormous and inexpensive labor attracts foreign investments, including Taiwanese investment, to enter Mainland China¡¦s market, and, further, drives economic development of Asia-Pacific Region. However, from the viewpoint of Rural-Urban Dualism theory, on the social level, rural labors can not take part in political life, and preserve their rights. Thus, they become ¡§Silent Class¡¨ in the Chinese urban society. On the economic level, serious public security problems derivative from labor disputes and conflicts, and it attracts highly concerns of Central of Chinese Communist Party (CCP), and issues ¡§Constructing Harmonious Community and Well-Off Society¡¨; and on the social level, continued expanding poverty gap, social rejection, and prejudice cause deep impact on those labors. This studying focus on the changing steps of supply and demand of rural labor, in order to discuss the developmental trend of transferring process of rural labor form past to present, even to the future. Therefore, this essay concentrates on the changing mobility of rural labor in some aspects, for example regions, identifications, careers, and life forms, and political, social economic, cultural, policy/urbanization, and market/occupation connections between rural and urban area. The Result of studying is, Central of CCP has 3 ways to solve problems beneath the surface of rural labor and urbanization: 1. Accelerating transferring process of rural surplus labor with economic development strategy; 2. Upgrading skill standard of rural labor, to guarantee employment; 3. Promoting and enlarging domestic consume, to constrain inflation. At the same time, the capability of labor unions should be reinforced and the organized degree of rural labor should be improved. Hoping that, they are able to play a more active role to protect rights of rural labors.
