Robotic System Design For Reshaping Estimated Human Intention In Human-robot Interactions

Durdu, Akif 01 October 2012 (has links) (PDF)
This thesis outlines the methodology and experiments associated with the reshaping of human intention via based on the robot movements in Human-Robot Interactions (HRI). Although works on estimating human intentions are quite well known research areas in the literature, reshaping intentions through interactions is a new significant branching in the field of human-robot interaction. In this thesis, we analyze how previously estimated human intentions change based on his/her actions by cooperating with mobile robots in a real human-robot environment. Our approach uses the Observable Operator Models (OOMs) and Hidden Markov Models (HMMs) designed for the intelligent mobile robotic systems, which consists of two levels: the low-level tracks the human while the high-level guides the mobile robots into moves that aim to change intentions of individuals in the environment. In the low level, postures and locations of the human are monitored by applying image processing methods. The high level uses an algorithm which includes learned OOM models or HMM models to estimate human intention and decision making system to reshape the previously estimated human intention. Through this thesis, OOMs are started to be used at the human-robot interaction applications for first time. This two-level system is tested on video frames taken from a real human-robot environment. The results obtained using the proposed approaches are compared according to performance towards the degree of reshaping the detected intentions.

Predicting Ecological Behavior in the Era of Climate Change

Street, Jalika C. 07 May 2011 (has links)
The most devastating effects of climate change may be avoided if humans reduce activities that produce greenhouse gases and engage instead in more sustainable ecological behaviors. The current mixed methods study of 279 undergraduate students explored whether environmental worldview, belief in climate change, knowledge of climate change, personal efficacy, and intention to address climate change influenced participants’ engagement in ecological behavior. Results indicated that those with a stronger intention to address climate change and a more ecocentric worldview reported significantly more ecological behavior. Next, the study examined whether participants’ intentions to address climate change mediated the relationship between their belief in climate change and engagement in ecological behavior and whether intentions mediated the relationship between efficacy and ecological behavior. Intentions to address climate change did not mediate the relationship between belief and ecological behavior but fully mediated the relationship between efficacy to address climate change and ecological behavior.

Customer Equity Drivers and Purchase Intentions : Examining the Customer Equity Framework in the Retail Clothing Industry in a Swedish Context: H&M and Gina Tricot as the Case Study

Torres Telles, Monica Violeta, Mazhari, Shadi January 2011 (has links)
The customer equity framework was created by Rust et al. in 2000 after studying severalspecific industries. We use this framework as the theoretical basis for this study to examine the relative impact of the three customer equity drivers- value equity, brand equity and relationship equity- across two brands in the retail clothing industry on purchase intentions of young consumers. Based on the responses of 156 female university students who are the target for the two brands studied, value equity is the most important customer equity driver for customers whereas, for H&M relationship equity was the driver which had the greatest influence on purchase intentions while for Gina tricot brand equity had the greatest impact on purchase intentions.

Carlsson, Lisa J., Chehimi, Sara January 2011 (has links)
Recently, many high-end fashion designers have established their own e-commerce site. However, due to the difficulties of replicating the brick and mortar environment and the increase of competition, it has become more difficult to convert visitors into buyers. In order to attract buyers, some retailers add a lot of multimedia content. The purpose of this thesis is to investigate attitude towards multimedia and whether it influences one’s online purchasing intentions for high-end fashion.

Makten på andra sidan datorskärmen : En studie om bloggens makt på unga kvinnors upplevda köpintentioner / The power on the other side of the computer screen : A studie of the blog's effect on young women's percieved purchase intentions

Steen, Nathalie, Kasto, Nanci, Frylén, Sandra January 2012 (has links)
Antalet bloggar växer och läsarantalet för bloggar likaså, framför allt har en ökning märkts hos unga kvinnor (Findahl, 2011). Att bloggläsandet har ökat medför att läsaren sätter sig själv i en situation där de kan utsättas för påverkan, både i form av bloggtext samt reklam i form av annonser. Frågan är om det nya bloggfenomenet nu kommer att ta över som en ny marknadsföringskanal gentemot de traditionella annonsreklamerna. Kommer de personliga blogginläggen att påverka mer än traditionell reklam? Syftet med denna studie är därför att undersöka om unga kvinnor upplever att deras köpintentioner påverkas av bloggar. Genom att undersöka om ett specifikt blogginlägg har en uppfattad påverkan på unga kvinnor och deras upplevda köpintentioner jämfört med en annons, ämnar vi att öka förståelsen för bloggar och makten bakom datorskärmen. För att uppfylla syftet behandlades följande två hypoteser; 1.    Unga kvinnors bloggvanor uppfattas ha en påverkan på dem och deras upplevda köpintentioner. 2.    Blogginlägget har en större uppfattad påverkan på unga kvinnors upplevda köpintentioner jämfört med annonsen För att undersöka detta tilldelades respondenterna slumpmässigt två olika enkäter vid undersökningstill-fällena. Den ena enkäten mätte den uppfattade påverkan av ett produktinriktat blogginlägg, den andra av en annons. Respondenterna är utvalda med hjälp av ett bekvämlighetsurval och består av 128 unga kvinnor som går sista året på gymnasiet. Undersökningen har bedrivits under skoltid på fyra av de största gymnasieskolorna i Jönköping. Datamaterialet som samlades in från enkätundersökningen matades sedan in i ett program för statistikbehandling, SPSS. Dessa grupper jämfördes sedan statistiskt för att kunna antingen förkasta eller acceptera hypoteserna. Resultatet av undersökningen visar att respondenterna upplever att deras köpintentioner blir påverkade av deras vanor av bloggar. Det visar även att sambandet mellan deras bloggvanor och upplevda köpintentioner är positivt. De vars bloggvanor är mer frekventa har också större intentioner att handla något som de har läst om i ett blogginlägg. De upplever också att deras köpintentioner påverkas mer av ett blogginlägg än av en annons. Skillnaden är dock liten. / Blogs are increasing in popularity, especially among young women, both when it comes to writing blogs and reading them (Findahl, 2011). As a consequence, readers are putting themselves in a situation where they are being exposed to influence. The question arisen from this is whether blogs should be given more attention and if companies should consider them part of their marketing strategies. Will the personal blog posts have a greater effect on consumers compared to traditional advertising? The purpose of this study is therefore to investigate if young women perceive that their purchase intentions are influenced by blogs. By investigating if a specific blog post has a perceived influence on young women and their purchase intentions compared to an advert, we aim to increase the understanding within the subject of blogs and to recognize the power on the other side of the computer screen. In order to fulfill the purpose, following hypothesis were addressed: 1.    Young women’s experiences of blogs are perceived to have an influence on them and their per-ceived purchase intentions. 2.    The blog post has a greater influence on young women and their perceived purchase intentions compared to the advert. The respondents were randomly allocated two different surveys where one measured the respondent’s perceived influence from blog posts and the other measured the respondent’s perceived influence from an advert. The sample was conducted by the use of convenience sampling and consisted of 128 young women who all are attending their last year in high school in the four largest schools in Jönköping. In order to receive statistical results, the collected data from the surveys were entered in a statistics program called SPSS. The groups were then compared in order to establish if the hypotheses would be rejected or accepted. The results from the study show that the respondents experience that their purchase intentions are influ-enced by blogs. Furthermore, there is a positive correlation between their blog experiences and their per-ceived purchase intentions; those who are more frequent in their use of blogs, have more intentions to buy something that they have read about on blogs. They also experienced that their purchase intentions are influenced more by the blog post than the advert. The difference is small though.

Comparison Research of Taiwan Adolescent Subculture Consumer Groups: Empirical Studies of Otaku and Pop Music Fans

Chiang, Yung-Sung 11 January 2012 (has links)
High accessibility to internet technology and popularization of focus media has given rise to various emerging subcultures among the younger generation who constantly seek novelty and unique lifestyles. The Otaku subculture is one such adolescent subculture, a culture of avid ACG (animation, comic, games) collectors, while pop music fans belong to another youth subculture deeply involved in gathering and tracking the lives and performances of pop music stars. As the adolescent is becoming the most purchasing power consumer group of fashion product, this research aims at comparing the traits of the above two adolescent subcultures and their influences on buying behavior tendencies toward subculture-specific merchandises. This research is also attempting to develop an analytical model through comparison of two studies. The research framework is constructed based on the assumption that the traits of adolescent subcultures influence the subculture-specific consumptions and is examined on two studies of Otaku and pop music fans subcultures respectively. The same investigation methods are applied in two studies. First, the review of prior studies and findings of focus group interview with sample of five representative adolescents were integrated into a tentative model. Then, the questionnaire was developed based on the tentative model and the focus group interview findings, and sample of survey in two studies are 105 and 101 respectively. Survey data were examined by factor analysis and structural equation modeling for the verification of the tentative model, and finally a revised model is developed based on comparison of two studies results. Results show that the personality, values and lifestyle of subculture¡¦s main traits dimensions influence their buying behavior, although the Otaku and pop music fans take part in different activities and embrace different personality traits and values. The results also verify a feasible generalized analytical model for measuring the influences of the traits of specific adolescent subcultures on their buying behavior. This research offers some implications for consumer behavior and marketing communication including (1) comprehensive customer investigation is needed to understand what adolescents think and want; (2) providing attractive content and (3) adopting modern media to attract and access adolescent subculture group; (4) marketing communication appeals should match adolescents self-images to get their identification; and (5) providing total subculture solution in integrated marketing programs.

How to enhance newcomers' retention and performance? Exploring the moderating effects of mentoring and newcomers' personality on the relationships between newcomers' Person-Job fit/Person-Organization fit and task performance/turnover intentions

Huang, Shu-Chen 07 September 2012 (has links)
In order to enhance newcomers' retention and performance, the present study explored the moderating roles of mentoring and newcomers' personality (conscientiousness and emotional stability) on the relationships between newcomers' perceived person-job fit, (P-J fit) person-organization fit (P-O fit) and their task performance and turnover intentions. The data was collected from newcomers who have passed probation with their organizational tenure less than one year. In total, 198 usable questionnaires were collected from 20 firms in Taiwan. The present study applied the hierarchical regression analysis to test our hypotheses. The results showed that: (1) when mentoring relationship is low, the positive relationship between newcomer P-J fit and task performance is strengthened; (2) when conscientiousness and emotional stability are high, the negative relationship between newcomers P-O fit and turnover intentions is strengthened; (3) the interaction between newcomer P-J fit and P-O fit is positively related to task performance. Based on our findings, we proposed several practical implications as below: (1) organizations should pay attention to newcomers¡¦ P-J, P-O fit, and their socialization processes; (2) using selection tools to hire newcomers with high conscientiousness and emotional stability; (3) organizations should apply different socialization practice for newcomers with different attributes.

Correlates Of Organizational Commitment: A Special Emphasis On Organizational Communication

Ok, Afife Basak 01 February 2007 (has links) (PDF)
The aim of this study was to examine the relationships among individual and organizational characteristics variables, several aspects of organizational communication, organizational commitment, organizational identification, job satisfaction, and turnover intentions. Furthermore, the influence of supervisor and workgroup commitment on organizational commitment was also examined. With these purposes, following two different pilot studies, questionnaires were administered to a sample of 321 white collar bank employees who are working in different branches of different banks in Ankara. The results of the study revealed that influence of individual and organizational characteristics variables on job satisfaction, organizational identification, organizational commitment, and turnover intentions were low and most of the time insignificant. The results of both regression analyses and model test indicated that job satisfaction was significantly and positively predicted by downward instrumental communication and turnover intentions was found to be significantly predicted by upward instrumental and downward positive communication and organizational identification was found to be significantly predicted by downward instrumental communication in the model test. Furthermore, both job satisfaction and organizational identification were found to be significant positive predictors of organizational commitment. In addition, organizational commitment was found to significantly and positively predicted by commitment to workgroup but not by commitment to supervisor. On the other hand, organizational commitment was found as a significant negative predictor of turnover intentions. However, when entered into the regression analysis together with organizational commitment, neither job satisfaction, nor organizational identification predicted turnover intentions significantly. However, significance of indirect effect of job satisfaction and organizational identification on turnover intentions through organizational commitment confirms the mediation of organizational commitment. The results of the present study, its limitations, and implications were discussed in more detail in the light of the relevant empirical evidence.

Antecedents And Consequences Of Organizational Commitment

Ekrem Duman, Fatima Betul 01 September 2010 (has links) (PDF)
In the present study, organizational commitment&lsquo / s relationship with a number of antecedents and consequences were examined. In more detail, firstly the effects of job characteristics (i.e., job variety, promotional opportunity, organizational fairness, and perceived organizational support) on three dimensions of organizational commitment namely affective, normative, and continuance commitment were examined. Secondly, how these three dimensions of organizational commitment predict two dimensions of performance (i.e., task and contextual performance) and turnover intentions were examined. With these purposes, a pilot study was conducted with the participation of 45 employees and then in the main study questionnaires were administered to a sample of 175 employees working in different public organizations. According to the results of the study, job characteristics significantly and positively predicted both affective and normative commitment in addition to overall commitment but they were not significant predictors of continuance commitment. In more detail, affective commitment was predicted by job variety, promotional opportunity and perceived organizational support while normative commitment was predicted by job variety and perceived organizational support. The results of the mediation analysis revealed that perceived organizational support partially mediated the organizational fairness - affective organizational commitment relationship. Among three dimensions of commitment, affective and normative commitment were found to significantly and negatively predict turnover intentions of employees. On the other hand, none of the three dimensions significantly predicted task performance when self ratings were used but affective and normative commitment significantly influenced self reported contextual performance. However, three dimensions of commitment were not significant predictors of task, contextual or overall performance rated by supervisors. The results of the study, its implications, limitations and directions were future research were discussed in more detail.
