Analysis of Chinese millennial consumers' preference for online advertising channel in China / Analys av kinesiska milleniumkonsumenters preferenser av internetbaserade kanaler för marknadsföring i Kina

Zhang, Liwen, Song, Jinjing, Li, Xinyu January 2020 (has links)
An increasing number of foreign companies want to enter the Chinese market. Online advertising is one of the indispensable means of the company's operation and marketing, and foreign companies poorly understood the online advertising channels in China. Therefore, this study uses the AISAS model to study the preferences of Chinese millennial generation Taobao users for online advertising channels. And research through three dimensions are gender, city level and different product categories. Specifically, this research through online questionnaires and finally collected 150 samples, it was found that Chinese millennial generation Taobao users favored the promotion of WeChat public accounts, followed by Pre-movie adverts. Further, the study confirms that consumers do have preferences for online advertising choices and that they will change as they are placed on different e-commerce platforms. Based on the previous study's interpretation of preferences, the preferences are defined as five exact post behaviors to better evaluate consumers' choices for online advertising. Moreover, through data analysis, it is found that there are differences between male and female online advertising channels among Chinese millennial generation Taobao users. Females prefer online advertising channels that are interactive than males such as live streaming. Males prefer online advertising channels that are dominated by pictures/images for instance mini banners in App and Web. In addition, live streaming has an advantage in the household goods category.

Myš, potkan, krysa: prostor, pach a metody detekce / Mice and Rats: Space, Smell and Methods of Detection

Kaftanová, Barbora January 2018 (has links)
The coexistence of humans and rodents lasts from the beginnings of the history of agriculture. Many rodent populations accepted to synanthropic way of life and as commensals accompany human societies until today. In the first study we wanted to find out, how the evolution of non-commensal rodent species, a Cypriot mouse (Mus cypriacus), was influenced by people. This endemic island species evolved on the Cyprus Island without presence of any mammalian competitors or predators. In last 10.000 years humans arrived on the island, bringing several mammalian species, which affected the environment markedly. A black rat (Rattus rattus) is now dominant species there and presumably it is an important competitor for the Cypriot mouse. We supposed that the mice should avoid its odour. Nevertheless the rats odour was preferred by the mouse, probably as an odour of phylogenetically related species. On the contraty, the odour of domestic cat (species, which is also widespread on the island), was avoided. In conclusion, the long-term isolation from mammalian predators did not affect the antipredatory reactions of the Cypriot mouse. Our next study was focuse on changes in behavioural strategies of different populations of mice: the main question was how the commensal way of life affects their exploratory...

BAYESIAN METHODS FOR LEARNING AND ELICITING PREFERENCES OF OCCUPANTS IN SMART BUILDINGS

Nimish M Awalgaonkar (12049379) 07 February 2022 (has links)
<p>Commercial buildings consume more than 19% of the total energy consumption in the United States. Most of this energy is consumed by the HVAC and shading/lighting systems inside these buildings. The main purpose of such systems is to provide satisfactory thermal and visual environments for occupants working inside these buildings. Providing satisfactory thermal/visual conditions in indoor environments is critical since it directly affects occupants’ comfort, health and productivity and has a significant effect on energy performance of the buildings. </p> <p>Therefore, efficiently learning occupants’ preferences is of prime importance to address the dual energy challenge of reducing energy usage and providing occupants with comfortable spaces at the same time. The objective of this thesis is to develop robust and easy to implement algorithms for learning and eliciting thermal and visual preferences of office occupants from limited data. As such, the questions studied in this thesis are: 1) How can we exploit concepts from utility theory to model (in a Bayesian manner) the hidden thermal and visual utility functions of different occupants? Our central hypothesis is that an occupant’s preference relation over different thermal/visual states of the room can be described using a scalar function of these states, which we call the “occupant’s thermal/visual utility function.” 2) By making use of formalisms in Bayesian decision theory, how can we learn the maximally preferred thermal/visual states for different occupants without requiring unnecessary or excessive efforts from occupants and/or the building engineers? The challenge here is to minimize the number of queries posed to the occupants to learn the maximally preferred thermal/visual states for each occupant. 3) Inferring preferences of occupants based on their responses to the thermal/visual comfort-based questionnaire surveys is intrusive and expensive. Contrary to this, how can we learn the thermal/visual preferences of occupants from cheap and non-intrusive human-building interactions’ data? 4) Lastly, based on the observation that the occupant population decompose into different clusters of occupants having similar preferences, how can we exploit the collective information obtained from the similarities in the occupants’ behavior? This thesis presents viable answers to the aforementioned questions in the form of probabilistic graphical models/frameworks. In future, I hope that these frameworks would prove to be an important step towards the development of intelligent thermal/visual systems which would be able to respond to occupants’ personalized comfort needs. Furthermore, in order to encourage the use of these frameworks and ensure reproducibility in results,various implementations of this work (namely GPPref, GPElicit and GPActToPref) are published as open-source Python packages.</p><br>

Long-Term Effectiveness of Brief Multiple-Stimulus Without Replacement Preference Assessments on Individualized Education Plan Reading Progress of Students with Severe Disabilities

Thornton, Heather C 01 December 2008 (has links)
To teach operant behaviors to individuals with severe disabilities, stimulus preference assessment (SPA) methods have been developed to accurately identify stimuli that may function as reinforcers. Previous researchers have used multiple-stimulus preference assessments without replacement (MSWO) effectively over a short time period to teach target behaviors to individuals with disabilities. The present study investigated the long-term effects of incorporating brief MSWO preference assessments into the instructional routine for students with severe disabilities on individualized education plan reading goal/objective progress. This was done by investigating the effectiveness of incorporating brief MSWO preference assessments by comparing reading goal progress when a random reinforcer is available, teacher- selected reinforcer is available, or a student-selected reinforcer (via a brief MSWO preference assessment) is available over several weeks for students with severe disabilities in a secondary public school classroom setting.

Beach Users Perception of Design Alternatives of a Man Made Beach

Rayburn, Shelby Hooker 12 August 2016 (has links)
The 42-kilometer beach in Harrison County, Mississippi necessitates continual re-nourishment projects to ensure its survival due to constant erosion events. The stability that the root structures of vegetated beaches provide have been shown to be a countermeasure to these erosion events. It has also been shown that the public will utilize landscapes that they find to be attractive. Therefore, the purpose of this thesis is to ascertain whether beach users find vegetated beaches more attractive than un-vegetated beaches. In several Harrison County communities, beach users were surveyed through the use of a Visual Preference Survey and an accompanying questionnaire to determine their opinions on the design of the beach, its design elements, and the purpose of those elements. Results were mixed, however it was determined that beach users found beaches vegetated with multiple types of florae to be more attractive than non-vegetated beaches.

We're Listening: A Study of Music Preference in Modern Society

Glover, Michael B. 01 January 2023 (has links)
The purpose of this study was to investigate the formation of music preference in an effort to identify specific ages when preferred music is likely to be discovered. One hundred one individuals participated in an online survey, answering questions about their listening habits, music preferences, and the social elements that contributed most to those preferences. Participants were asked to identify their current, second, and third favorite music at the time of the study and whether their preferences had changed over time. According to findings, males were likely to discover their current favorite music at the age of 12.46 years, and females were likely to discover their current favorite music at the age of 13.23 years. Parents, friends, and the radio were shown to be the most common influences towards preference discovery. Of those surveyed, 69.3 % of participants acknowledged that their preferences had changed over time. However, the current methodology lacked the specificity to determine the scope of that change, leaving room for future study. The results hold implications for not only the field of music therapy, but also for any other fields utilizing preferred music to achieve a specific result.

Vliv centrální serotoninergní a dopaminergní aktivity na nutriční a metabolické parametry / The influence of central serotoninergic and dopaminergic activity on nutritional and metabolic parameters

Brunerová, Ludmila January 2013 (has links)
THE INFLUENCE OF CENTRAL SEROTONINERGIC AND DOPAMINERGIC ACTIVITY ON NUTRITIONAL AND METABOLIC PARAMETERS MUDr. Ludmila Brunerová SUMMARY Introduction: Neuromediators dopamine and serotonin play a significant role in homeostatic and hedonic regulation of food intake, may exert direct metabolic effects and particularly serotonin influences affectivity. Their central activity could be quantified by functional tests. Common regulatory mediators of metabolism and affectivity represent an interesting research goal. Aims of study: The first aim was to describe the relationship between central serotoninergic activity measured by citalopram challenge test, affectivity, preference of macronutrients in food and metabolic profile in healthy men. The second aim was to confirm the use of sublingual apomorphine test as a functional test for assessment of central dopaminergic activity. The third aim was to reveal the relationship between central dopaminergic activity measured by sublingual apomorphine test, preference of macronutrients and metabolic profile. Methods: The study was performed on 42 healthy men (average age 43.5 ± 7.4 years and average BMI 27.4 ± 5.7 kg/mš) within 4 days with a week interval in between them. Anthropometric and...

Residential Preference at Transit-oriented Development: A Visual Choice Experiment

Alsaiari, Hamad Nasser 28 November 2018 (has links)
Insufficient knowledge of residential preferences represents a major obstacle to achieving residential satisfaction and quality of life. This obstacle is even greater in the case of transit-oriented developments (TODs), as their success depends, in part, on the degree to which people's preferences are consistent with their residential environments. This study employed a visual choice experiment, which combines the benefits of visual preference surveys and discrete choice experiments, to elicit residential preference for TODs in Riyadh, Saudi Arabia, before the opening of its citywide public transportation system. Using a seemingly homogeneous sample of participants, the analysis incorporated three analytical methods to elicit residential preference: a multinomial logit model, a mixed logit model, and a latent class model. The results indicated the presence of preference heterogeneity and the emergence of four lifestyle classes that could explain and predict residential preference patterns. People with similar sociodemographic characteristics may have different lifestyles based on their choice behavior, marital status, and public transit attitudes. Additionally, the results showed a strong preference for low-density housing, even among those who favor living in a TOD; however, increasing density could be mitigated through the presence of other TOD attributes. The findings of this research point to the diversity of residential preferences and suggest that providing a variety of residential environments increases the likelihood that people will find their preferred environment. Additionally, planning efforts to convert all developments near transit, particularly in suburban locations, to TODs might be unsuitable in cities where public transportation has been introduced only recently. Instead, deferring TOD conversion efforts until public transportation and its use are mature may attract people to live near transit and encourage the gradual development of transit affinity in residents who may otherwise reject TOD living completely. Lastly, the successful application of a visual choice experiment in this research opens up a variety of potential analytical methods that are used commonly in other fields and have the potential to move visual preference research into the realm of robust empirical investigation. / Ph. D. / The work of urban planners, urban designers, architects, and policy makers centers on improving the built environment and increasing the quality of people’s lives. However, their work entails making decisions that are not always in tandem with people’s preferences (e.g., increasing housing density, proposing a mix of land uses in residential neighborhoods, introducing public transportation close to where people live and work, to name a few). Due to the uncertainty surrounding people’s acceptance of modifications of the built environment, especially when it entails introducing residential attributes for the first time, this dissertation focused on 1) assessing residential preference near public transportation nodes in Riyadh, Saudi Arabia before operation of the public transportation system, and 2) assessing the extent to which advanced analytical methods are capable of providing a better understanding of residential preference differences among a seemingly homogenous sample of participants. The work in this dissertation was motivated by the increasing use of manipulated images in choice tasks, where participants are presented with multiple images, each depicting a residential scenario, as bundles to choose from, and their choice patterns then recorded and analyzed. The results showed that among the relatively homogenous sample of participants that was recruited, four significant residential preference patterns have emerged, which could be used to describe and predict residential preference and choice with great accuracy. This dissertation laid out several policy implications that could be useful in providing a built environment that matches with what people want. It also provided research implications and suggestions on the use of visual choice experiments for urban planners and designers that are well-developed in other fields of inquiry.

Média a předvolební výzkumy: kvantitativní obsahová analýza vybraných českých deníků před volbami do PSP ČR v roce 2010 / Media and pre-election polls:quantitative analysis of the Czech major daily newspapers before parliamentary elections in 2010

Kálalová, Kateřina January 2012 (has links)
The thesis titled Media and Pre-Election Polls: Quantitative Analysis of the Czech Major Daily Newspapers before Parliamentary Elections in 2010, deals with the manner in which the media grasp and process the results of opinion polls focused on the theme of elections, namely pre-election polls. The attitude of the author toward this topic is based on the agenda setting theory, which assumes that the media can, to some extent, set the topics and thus determine how (and that) the audience think about them. In the case of publication of pre- election surveys can therefore media, to some, but hardly detectable extent, influence the citizens-voters. For this reason it is important to focus on how exactly the mass media work with the statistic data and how they make them available to the wide public. Media coverage of these data should be complete and clear in order to prevent misinterpretation and for the data to be correctly handled. Through the quantitative content analysis of media outputs (in total 74 articles) from the five most popular Czech daily newspapers in the period January to May 2010 it was researched if the media work with pre-election polls results properly. Based on the analysis and its results, the recommendations were concluded for the situation to be improved.
