Motivations for Studying French: Language Orientations and Expectancy-Value Theory

Newbill, Paula Brown 01 May 2009 (has links)
French enrollment is not increasing at the rate of other modern languages in higher education in the United States. This study attempted to bring to light the reasons for studying the language and focused on the orientations, expectancies, and values students have for studying French at a large, public university. The mixed methods research investigated students' reasons for enrolling in an intermediate French course with a self-report survey including short answer questions. The aim of this principally quantitative study was to understand why students choose to study French by comparing the subscales within the orientations and expectancy-value scales. The foreign language orientation subscales used were: travel, knowledge, relationships, instrumentality, and the sociocultural orientation. For the expectancy-value scale, the subscales included: expectancy, intrinsic value, attainment value, and utility value. The mean values of the survey items were compared in an ANOVA framework. Relationships within the two scales were analyzed using a Pearson's correlation calculation. Finally, a linear regression was used to analyze the subscales as predictors of continuation of French study. Short answer responses supported the quantitative data through resulting themes and sub-themes. The data were merged in a validating quantitative data model of mixed methods. Results for foreign language choice pointed to travel reasons, such as the desire to spend time abroad, and intrinsic interest in the language. Students were likely to continue studying French due to sociocultural reasons, such as understanding French films and music, and due to instrumental reasons involving career and grades. The attainment or importance subscale of the expectancy-value scale was the best predictor of continuation. The short answer qualitative data were transformed to show the significant subscale orientations with corresponding sub-themes. The triangulation offered insight into FL choice and communication with people in francophone countries. The findings also suggested that students continue studying French due to particular career choices. Teaching implications and further study suggestions offer ideas for the significant subscales. The subscales that obtained low mean values in FL choice are also included in the implications section. This is due to the fact that the low scoring subscales are areas that have not been explored to encourage French study. Further study is needed to provide more details about students' experiences through interviews and to implement educational suggestions with enrollment tracking. The mixed methods design offers a base for similar FL motivation studies in the future. / Ph. D.

A study on Consumer¡¦s adoption of Mobile TV

Cheng, Huei-ying 30 August 2010 (has links)
Because of the popularity of the 3G mobile technology and the development of digital broadcasting technologies, the mobile television (TV) has become a potential killer application within the telecom industry. This research examines mobile user¡¦s intention to use and the use behavior of mobile TV. The theory underlying the study is the unified theory of acceptance and use of technology (UTAUT) that takes performance expectancy, effort expectancy, social influence, and facilitating condition as independent factors and the intention and behavior of usage as dependent variables. Two online surveys were conducted to evaluate the theory. The result from the first survey shows that the performance expectancy, the effort expectancy and the social influence factors have significant influences on the mobile TV user¡¦s intention toward using mobile TV services. The facilitating condition has a positive significant relationship with the usage behavior. The result different from the previous studies is no significant relationship between the intention and use behavior. However, the follow-up survey conducted a year later shows that the facilitating condition and intension to use have positive significant impacts on the use behavior. This study can help firms to better understand the factors that affect the intention and behavior of using mobile TV.

Hung, Jung-chih 14 May 2008 (has links)
Instant Messaging ¡]IM¡^ has becomes an important tool of communication. Currently, eighty percent of the Internet users use IM to communicate each other. This study uses the dimensions of performance expectancy and effort expectancy of the Unified Theory of Acceptance and Use of Technology and the interpersonal communication need to investigate factors that influence IM acceptance. There are 211 completed questionnaires were returned and analyzed. It¡¦s found that performance expectancy, effort expectancy, and interpersonal communication show significantly positive and significant impacts on IM users¡¦ intention. The intention significantly and positively affects their IM usage. According to the results, it¡¦s suggestted that IM software should make the IM more user-friendly and the software interface is not too complicated, so that users might feel that IM software is easy to use.

Evaluation of a Digitally-Automated Alcohol Curriculum Designed to Alter Expectancies and Alcohol Use in First Year College Students

Schreiner, Amy 01 January 2014 (has links)
High-risk alcohol consumption remains a primary public health concern for students on college campuses. In response to this concern the National Advisory Council of the National Institute on Alcohol Abuse and Alcoholism created a task force to identify and recommend strategies to aid college administrators in implementing effective alcohol programming at their institutions. While most administrators report being aware of these recommendations, many have not successfully implemented empirically supported interventions on their campuses. One significant barrier is the cost and difficulty of training and hiring skilled staff to implement these interventions. Of the strategies identified as effective, challenging alcohol expectancies is the only strategy validated for group administration with college students and has significant potential to address this remaining barrier. However, current expectancy-based interventions still require highly trained expert facilitators for implementation. The present study aimed to convert the previously validated Expectancy Challenge Alcohol Literacy Curriculum (ECALC) into a digital format amenable to non-expert facilitation. The resulting digital ECALC was implemented in 48 class sections of a first year student course in a group randomized trial. It was hypothesized that receiving the digital ECALC would result in significant changes in alcohol expectancies and subsequent changes in alcohol use and related harms. Analyses revealed significant changes in both positive and negative expectancies following the digital ECALC, however no significant changes in alcohol consumption or alcohol-related harms were observed at a 30 day follow-up. Exploratory subgroup analyses revealed significant differences between experimental and control groups on average and peak drinks per sitting for classes receiving the digital ECALC during the fall semester only. Semester specific variables, environmental context, and social influence variables may have contributed to the lack of behavioral changes in the overall sample following observed expectancy changes. This study represents an important development in expectancy-based interventions for college students as the digital format removed the need for an expert facilitator and maintained significant changes in expectancies. Future studies should focus on replication of these expectancy changes and on demonstrating subsequent changes in alcohol use and related harms. The present study also represents the first evaluation of a group-administered expectancy intervention to report on intra-class correlations which will aid future researchers in designing sufficiently powered studies going forward.

Exploring Cyber Ranges in Cybersecurity Education

Beauchamp, Cheryl Lynn 01 April 2022 (has links)
According to a report from McAfee, the global cost of cybercrime for 2020 was over one trillion dollars (Smith, Z. et al., 2020). Cybersecurity breaches and attacks have not only cost businesses and organizations millions of dollars but have also threatened national security and critical infrastructure. Examples include the Ransomware attack in May of 2021 on the largest fuel pipeline in the United States and the February 2021 remote access system breach of a Florida water treatment facility which raised sodium hydroxide to a lethal level. Improving cybersecurity requires a skilled workforce with relevant knowledge and skills. Academic degree programs, boot camps, and various certification programs provide education and training to assist this need. Cyber ranges are a more recent development to provide hands-on skill training. These ranges, often virtual, provide a safe and accessible environment to improve practical skills and experience through hands-on application. They provide a training environment to identify threats, apply countermeasures, and secure data from risks separately from the organization's actual network. More and more academic programs utilize cyber ranges due to the perceived benefit of integrating them into their cybersecurity-related programs. Academic cyber ranges offer virtualized environments that support cybersecurity educators' needs to provide students with a safe, separated, and engaging environment. The purpose of my research has two components: 1) to understand who the educators are using academic-facing cyber ranges and how they are using them to support their cybersecurity education efforts, and 2) to understand how cybersecurity educators and students are motivated by using them. Specifically, my research is comprised of three manuscripts: (1) a mixed-method exploratory study of who are the educators using cyber ranges for cybersecurity education and how they are using them to create significant cybersecurity learning experiences, (2) a mixed-method study exploring the motivation of educators using a cyber range for cybersecurity education, and (3) a mixed-method study exploring student motivation participating in cybersecurity CTF competitions. The three manuscripts contribute to understanding cyber ranges in cybersecurity education. The results from my research provided insight from the users of these cyber ranges, cybersecurity educators and students. Results from my first manuscript suggested that high school cybersecurity educators are the primary users. These educators have less formal cybersecurity education and experience compared to cybersecurity educators in higher education. The data also showed that cybersecurity educators primarily used cyber ranges for teaching and learning to meet learning goals and objectives. Results from my second manuscript suggested that educators were motivated mainly by the importance of using a cyber range for cybersecurity education and for the interest-enjoyment their students experience from cyber range usage. Educators found using the cyber range made their class more engaging and relevant to their students.These educators were also confident they could use a cyber range and learn how to use it. However, those without prior experience in cybersecurity or previous experience using a cyber range shared they needed instructor-facing resources, professional development opportunities, and time to learn. Results from my third manuscript suggested that students were motivated by the importance of participating in a cybersecurity CTF competition. Many reported that participating was useful for developing professional skills and readiness. Although CTF competitions were considered difficult and stressful, students did not consider the difficulty pejorative. Many shared that challenging CTFs contributed towards the enjoyment of participating, making them a rewarding and worthwhile experience. However, students also shared that academic and team support contributed towards their confidence in competing. In contrast, those who did not report confidence, stated they lacked a team strategy or support from their academic institution. Additionally, they did not know what to expect to prepare before the competition event. Overall, the results of this dissertation highlight the importance of prior preparation for educators and student CTF participants. For educators, this prior preparation includes curriculum supporting resources such as content mapping to learning objectives and professional development opportunities that do not assume any prior knowledge or experience. For students, prior preparation includes understanding what to expect and recommendations for academic and team support. / Doctor of Philosophy / The technology era has enabled a global connectedness to attend conferences and meetings via our laptop computers while working from home. The proliferation of smart devices has also provided a means to view and communicate with visitors who ring our smart doorbells while we are not home. This interconnected network, i.e., the Internet, has altered how we pay our bills, buy our groceries, and attend classes virtually. It has also enabled cyber attacks and breaches that have contributed to identity thefts, increasing financial costs, business collapses, job losses, and even threatened national security. A cybersecurity workforce has become increasingly vital to address the need for improving cybersecurity. Thus, there is a need for academic cybersecurity programs to prepare future professionals to fill this national workforce shortfall. Consequently, more and more organizations have integrated cyber ranges as the means to provide a simulated environment for applying and developing cybersecurity-related knowledge and skills. Similar to a driving range for a golfer to practice their golf swing or a shooting range for those in law enforcement to earn their firearms qualifications, a cyber range supports efforts to provide cybersecurity training with hands-on exercises and labs to practice skills in a safe, virtual environment. My research contributes to understanding who uses cyber ranges and how they are motivated to use them for cybersecurity education. The first purpose of my research was to understand the educators who were using cyber ranges and how they were using them for cybersecurity education. More specifically, I examined their usage for alignment with a learning taxonomy to verify the usage contributed to successful and significant student learning. This understanding contributed to my research's second purpose, which explored how educators were motivated using cyber ranges. The third purpose of my study explored student motivation using a cyber range. Due to varying cyber range resources and activities, my research focused on the cybersecurity competition activity, Capture the Flag (CTF). This study provided an understanding of how students who participated in a cybersecurity CTF competition were motivated. My research demonstrates that educators and students are interested in using cyber ranges and believe using them for cybersecurity education and professional readiness is important. However, both educators and students who lack prior knowledge or experience using a cyber range or participating in a CTF shared the concern of not knowing what they do not know. PD time and instructor-facing resources that do not assume any prior cybersecurity knowledge were recommended to support educators who did not have a background or experience in cybersecurity. Students shared that although not knowing was stressful and made participating difficult, the difficulty and stress were good attributes because if the CTF were easy, it wouldn't be worth their time and would be less rewarding. Students also reported that team strategies and academic support were motivational aspects of CTF participation. Overall, educators and students were motivated using cyber ranges for cybersecurity education, but professional development and preparation resources would contribute positively to their usage.

Search Engine Marketing in SMEs : The motivations behind using search engine marketing

Fahlström, Kamilla, Jensen, Caroline January 2016 (has links)
Abstract   Title: Search Engine Marketing in SMEs Level: Final assignment for Bachelor Degree in Business Administration Authors: Kamilla Fahlström & Caroline Jensen Supervisor: Jens Eklinder Frick Date: 2016 January Purpose: The purpose of this study is to use Expectancy theory to describe and analyze small company owners’ motivations for their usage of Search Engine Marketing, in terms of their perceived Valence, Expectancy and Instrumentality. Method: To research the aim of this study a qualitative research approach was used. The empirical data was compiled through ten semi-structured interviews from a varied selection of Swedish companies in the service sector. The data was analyzed with previous research to create an understanding of the motivations for using Search Engine Marketing. Conclusions: The result of this study, when analyzed alongside Expectancy theory, indicates that small business owners are motivated to use Search Engine Marketing. Furthermore, which method of Search Engine Marketing that the owners are motivated to use is dependent on their perceptions of the different methods. Future research: Due to the lack of research into the attitudinal and psychological aspects of Search Engine Marketing and the limitations of this study, it would be interesting if more research were done into this area. For example, it would be interesting to study if trust-based companies are motivated to use Search Engine Marketing, and if demographics affect the motivations. Contribution: This study contributes with results on a previously unexplored area within the research field of Search Engine Marketing. The study also contribute with some information to practice regarding small service company owners’ thoughts about their usage of Search Engine Marketing.  Key words: Search Engine Marketing, SMEs, Expectancy theory, Motivation, Website visibility

My Spider-Sense Needs Calibrating: Anticipated Reactions to Spider Stimuli Poorly Predict Initial Responding

Burger, Sarah Beth January 2012 (has links)
The present study attempted to answer two general questions: (1) what is the relation between expected and actual reactions to a spider in individuals afraid of spiders? and (2) are inaccurate expectancies updated on the basis of experience? Behavioral and cognitive-behavioral learning models of fear, treatment protocols developed in relation to these, and recent findings from our laboratory necessitated answers to two additional questions: (3) does the expectation accuracy of individuals who meet DSM-IV criteria for diagnosis with a specific phobia differ from that of individuals who are fearful but do not meet criteria? and (4) does expectation accuracy vary as a function of context? Two final questions were obvious: (5) do the actual reactions of individuals who meet criteria for diagnosis differ predictably from those of fearful individuals? and (6) do reactions vary contextually? Student participants reported and tested a series of trial-specific expectancies about their reactions to a live, mechanical, or virtual tarantula over seven trials. Participants then completed three final trials in the presence of a live tarantula. Participants poorly anticipated the quality and intensity of their initial reactions, but expectation accuracy increased quickly. No clear tendencies for over- or under-prediction emerged. Participants updated expectancies in relation to prior trial expectation accuracy, either increasing or decreasing their predicted reactions relative to the original expectancy. Participants who met criteria for diagnosis with a specific phobia consistently anticipated and reported more intense reactions than did those who were fearful, but diagnostic status was not predictive of expectation accuracy. Participants in the live and virtual spider groups reported similar levels of fear that were greater than those in the mechanical spider group. Participants in the virtual spider group more readily reduced the distance maintained between themselves and the spider stimulus than did those in the live or mechanical spider groups. Expectation accuracy did not vary contextually. Results are discussed in light of the theoretical models presented, with findings lending greater support to behavioral models of fear learning relative to cognitive models that postulate a substantial role for conscious processing and appraisal in specific fear. Practical recommendations are made to researchers and clinicians based on present findings.

A Cross-National Analysis of Labor Force Participation and Life Expectancy among Older Adults

Johnson, Jessica K. M. January 2010 (has links)
Thesis advisor: James E. Lubben / Productive aging is a new and evolving conceptual model that emphasizes the antecedents and consequences of productivity in later life. Proponents of productive aging claim that productive activity in later life is associated with a number of benefits for individuals, communities, and societies, but this assumption has not been widely tested at the country level. In the context of an adapted model of productive aging, the present study identifies the cross-national predictors of and relationship between one form of productivity (viz., labor force participation) and one aspect of well-being (viz., longevity) among older adults. Random effects models with pooled cross-sections and path analysis were used to analyze potential relationships with data from several international data sources. The complete cross-national longitudinal dataset consists of variables measured at five time points or during intervals centered at these time points (i.e., 1980, 1985, 1990, 1995, and 2000) for each of thirty countries that belong to the Organisation for Economic Co-operation and Development. The present study makes one particularly important and new contribution to the cross-national literature on productivity and longevity; the study suggests that work in later life strongly influences life expectancy among older adults, but that some important gender differences should be noted. The present study also suggests that public policy plays a very important role in country level labor force participation rates and life expectancy. More specifically, higher levels of public spending on social issues are associated with lower rates of labor force participation and higher life expectancies. Finally, the present study confirms that the adapted model of productivity provides a solid foundation for cross-national analyses of labor force participation and life expectancy, but highlights the importance of analyzing male and female behavior and outcomes separately. / Thesis (PhD) — Boston College, 2010. / Submitted to: Boston College.
