Consumption motives for luxury fashion products : effect of social comparison and vanity of purchase behaviour.

White, Samantha Karen January 2015 (has links)
This thesis aims to investigate the relationships between vanity, social comparison and purchase behaviour. Specifically, this thesis defines and develops a conceptual model that expands on these relationships where vanity and social comparison act as antecedents to consumers’ self-esteem and product evaluation which in turn gives rise to purchase behaviour for luxury fashion products. Using this model, the research examines how manipulations of social comparison and vanity are reflected in these relationships and the resulting impact on purchase behaviour. To empirically test this model, an online experiment using a 3x2 between-subjects factorial design was conducted, where respondents were exposed to modified print advertisements for luxury branded sunglasses. A total of 297 responses were collected from a pool of Amazon’s Mechanical Turk workers, which were analysed using multiple regression, factorial ANCOVA and path analysis to assess the hypothesised relationships. The results indicate that vanity appeals were indeed responsible for the way in which the product was evaluated which positively translated into purchase consideration. However, though social comparison was proven to negatively impact on self-esteem, this change in self-esteem was not significant in determining purchase behaviour. Additionally, social anxiety and public self-consciousness were found to be antecedents to the modelled relationships. The theoretical and managerial implications of these findings, along with suggested directions for future research, are discussed.

Understanding the machine readable numeric record: Archival challenges, with some comments on appraisal guidelines

Robbin, Alice January 1979 (has links)
In the past, raw information was frequently destroyed because it could not be stored, thereby precluding effective scholarly use of the materials. Today's computer technology allows preservation and compact storage of enormous quantities of highly detailed information. Maintenance of information in conventional paper format often required severe access restrictions to protect anonymity of particular cases, a problem which can be alleviated by utilizing the computer to delete or mask the identity of the individuals involved. The value of any archival record is enhanced by the existence of other sources, which when used in tandem more completely describe the social, administrative, or economic process. This is especially true of the machine readable record, where source materials from one file can be more easily linked with other files to provide more complete documentation of particular events and transactions, thus augmenting the potential value and increasing the analytic or explanatory potential of the original records.

Searching the long tail: Hidden structure in social tagging

Tonkin, Emma January 2006 (has links)
In this paper we explore a method of decomposition of compound tags found in social tagging systems and outline several results, including improvement of search indexes, extraction of semantic information, and benefits to usability. Analysis of tagging habits demonstrates that social tagging systems such as del.icio.us and flickr include both formal metadata, such as geotags, and informally created metadata, such as annotations and descriptions. The majority of tags represent informal metadata; that is, they are not structured according to a formal model, nor do they correspond to a formal ontology. Statistical exploration of the main tag corpus demonstrates that such searches use only a subset of the available tags; for example, many tags are composed as ad hoc compounds of terms. In order to improve accuracy of searching across the data contained within these tags, a method must be employed to decompose compounds in such a way that there is a high degree of confidence in the result. An approach to decomposition of English-language compounds, designed for use within a small initial sample tagset, is described. Possible decompositions are identified from a generous wordlist, subject to selective lexicon snipping. In order to identify the most likely, a Bayesian classifier is used across term elements. To compensate for the limited sample set, a word classifier is employed and the results classified using a similar method, resulting in a successful classification rate of 88%, and a false negative rate of only 1%.

The Role of Subjective Factors in the Information Search Process

Gwizdka, Jacek, Lopatovska, Irene January 2009 (has links)
This is an early access article. / We investigated the role of subjective factors in the information search process. Forty eight participants each conducted six web searches in a controlled setting. We examined relationships between subjective factors (happiness levels, satisfaction with and confidence in the search results, feeling lost during search, familiarity with and interest in the search topic, estimation of task difficulty), and objective factors (search behavior, search outcomes and search task characteristics). Data analysis was conducted using a multivariate statistical test (Canonical Correlations Analysis). The findings confirmed existence of several relationships suggested by prior research, including relationships between objective search task difficulty and the perception of task difficulty; between subjective states and search behaviors and outcomes. One of the original findings suggests that higher happiness levels before the search and during the search correlate with better feelings after the search, but also correlates with worse search outcomes and lower satisfaction, suggesting that, perhaps, it pays off to feel some â painâ during the search in order to â gainâ quality outcomes.

What Can Searching Behavior Tell Us About the Difficulty of Information Tasks? A Study of Web Navigation

Gwizdka, Jacek, Spence, Ian January 2006 (has links)
Task has been recognized as an influential factor in information seeking behavior. An increasing number of studies are concentrating on the specific characteristics of the task as independent variables to explain associated information-seeking activities. This paper examines the relationships between operational measures of information search behavior, subjectively perceived post-task difficulty and objective task complexity in the context of factual information-seeking tasks on the web. A questiondriven, web-based information-finding study was conducted in a controlled experimental setting. The study participants performed nine search tasks of varying complexity. Subjective task difficulty was found to be correlated with many measures that characterize the searcherâ s activities. Four of those measures, the number of the unique web pages visited, the time spent on each page, the degree of deviation from the optimal path and the degree of the navigation pathâ s linearity, were found to be good predictors of subjective task difficulty. Objective task complexity was found to affect the relative importance of those predictors and to affect subjective assessment of task difficulty.

A Scientometric Method to Analyze Scientific Journals as Exemplified by the Area of Information Science

Boell, Sebastian K. 12 1900 (has links)
==Background== In most academic disciplines journals play an important role in disseminating findings of research among the disciplinary community members. Understanding a discipline's body of journals is therefore of grave importance when looking for previous research, compiling an overview of previous research and and in order to make a decision regarding the best place for publishing research results. Furthermore, based on Bradford's Law of scattering, one can assume that in order to be able to compile a satisfying overview of previous research a wide range of journals has to be scanned, but also that there are some 'core' journals which are of more importance to specific disciplines than others. ==Aim== This thesis aims to compile a comprehensive master list of journals which publish articles of relevance to Library and Information Science (LIS). A method to rank journals by their importance is introduced and some key characteristics of the disciplines body of journals are discussed. Databases indexing the disciplines journals are also compared. ==Method== The master list of LIS journals was created by combining the journal listings of secondary sources indexing the field's literature. These sources were six databases focusing on LIS literature: INFODATA, Current Contents, Library and Information Science Abstracts, Library Information Science Technology Abstracts, Information Science and Technology Abstracts, and Library Literature and Information Science, the LIS subsection in three databases with a general focus: Social Science Citation Index, Academic Search Premier, and Expanded Academic ASAP, and the listing of LIS journals from the Elektronische Zeitschriften Bibliothek. Problems related to editorial policies and technical shortcomings are discussed, before comparing: predominant publication languages, places of publication, open access, peer review, and the ISI Journal Impact Factors (JIF). Journals were also ranked by the number of occurrences in multiple databases in order to identify 'core' publications. The number of journals overlapping between databases are estimated and a matrix giving the overlap is visualized using multi dimensional scaling. Lastly, the degree of journals overlapping with other disciplines is measured. ==Results== A comprehensive master list of 1,205 journals publishing articles of relevance to LIS was compiled. The 968 active journals are mostly published in English, with one third of the journals coming from the US and another third from the UK and Germany. Nearly 16% of all journals are open access, 11% have a ISIJIF, and 42% are peer reviewed. Fifteen core journal could be identified and a list of the top fourteen journals published in Germany is introduced. Databases have between five to 318 journals in common and the journal collection shows an substantial overlap with a wide range of subjects, with the biggest journal overlap with Computing Studies, and Business and Economics. ==Conclusion== The aim of compiling a comprehensive list of LIS journal was achieved. The list will contribute to our understanding of scholarly communication within the LIS discipline and provide academics and practitioners with a better understanding of journals within the discipline. The ranking approach proved to be sufficient, showing good similarity with other studies over the last 40 years. The master list of LIS journals has also potential use to further research.

Schoolisizing our Schoolyards: from a space to our place

Kyriakou, Aristea January 2014 (has links)
This study has been conducted in the context of the master program in Outdoor Environmental Education and Outdoor Life, of Linköping University. It aspires to investigate a specific part of outdoor environments: the schoolyards. Particularly, the aim of the study is to investigate how the use of the school grounds as an educational resource is influenced by their environments -rural or urban. The research compares the school communities’ (principals’, teachers’ and students’) perceptions about the use of their school grounds during the educational process. The research sample consists of 10 Swedish elementary schools, from which the five are in rural and five are in urban environments. The participants are in total 10 principals, 51 teachers and 295 students. Alongside, an observation recorded in a list and photographs enhance the comparison between the rural and urban schools’ infrastructures. From the 1268 photos taken, a selection is included in the study and constitutes the observation part. The study negotiates four controversial issues about school grounds’ capacities: space or place; good or bad; rural or urban; grounds of a school or grounds of a curriculum. The results, after all, reject the contradictions and the sections become respectively: a place for all seasons; neither good nor bad, just unique! ; Ideality stands for ideas; grounds for cooperation. It also becomes visible that even though the analysis of the responses confirms that the urban teachers hold the stereotypical idea that there are differences between rural and urban environments; the infrastructures of both environments do not appear different. However, the teachers’ different opinions and beliefs have a significant impact on the students’ responses. Specifically, significant differences are reported by students which align with the teachers’ differences. The rural and urban principals do not report significant differences, and in the great majority their opinions also align with their teachers’ opinions. Finally, a model which is unfolded through this study has central role, namely the schoolyard circle. This model aims to facilitate a process that I introduce as schoolisization, in which school grounds are used to extend the stereotypical learning environment by adapting the curriculum to a school’s needs. Consequently, the schoolyards’ transformation from a space to our place can be finally proved an outdoor education approach that “bridges contradictions” and promises better educational results.

Nurturing writing skills in the primary literacy lessons of the 'City of Film' : the impact of using moving images on attainment and motivation

Florack, Franziska January 2016 (has links)
Despite a constant rise in the attainment of Sats results year on year, the perception remains that British primary school children are underachieving and that they are reluctant readers and writers. In order to motivate their students, some teachers use films as a visual stimulus to provide students with ideas and create a personal and emotion connection with the written text. In the school years of 2013/14 I followed 21 primary classes which were taking part in a ‘film literacy’ scheme run by Bradford UNESCO City of Film. This initiative saw the training of teachers in the use of film as a tool in literacy lesson with the hope to raise attainment and motivation. Students and teachers completed questionnaires and interviews which were analysed in conjunction with observations and the students’ literacy grades. The research showed that both students and teachers recorded an increase in motivation. Further, significant progress in attainment also became evident: film literacy students raised their grades by 23.3% beyond the expected year-on-year increase. Improvements in inference, comprehension and vocabulary were especially praised. Students from schools with a low-income environment benefitted in particular. The research discusses six potential reasons for these changes, two of which are based on the belief that film is a particularly suitable medium for teaching as it engages students emotionally. Although the thesis acknowledges that Bradford involved a unique group of schools in the film literacy training and research, it nevertheless argues that film could be useful addition to primary classrooms due to its potential ability to raise standards and engage reluctant young writers.

An Evaluation of Discussion Board Instructions in Online Courses

January 2012 (has links)
abstract: The discussion board is a facet of online education that continues to confound students, educators, and researchers alike. Currently, the majority of research insists that instructors should structure and control online discussions as well as evaluate such discussions. However, the existing literature has yet to compare the various strategies that instructors have identified and employed to facilitate discussion board participation. How should instructors communicate their expectations online? Should instructors create detailed instructions that outline and model exactly how students should participate, or should generalized instructions be communicated? An experiment was conducted in an online course for undergraduate students at Arizona State University. Three variations of instructional conditions were developed for use in the experiment: (1) detailed, (2) general, and (3) limited. The results of the experiment indentified a pedagogically valuable finding that should positively influence the design of future online courses that utilize discussion boards. / Dissertation/Thesis / M.A. Communication Studies 2012
