Driver Acceptance of Advanced Driver Assistance Systems and Semi-Autonomous Driving Systems

Rahman, Md Mahmudur Mahmudur 12 August 2016 (has links)
Advanced Driver Assistance Systems (ADAS) and semi-autonomous driving systems are intended to enhance driver performance and improve transportation safety. The potential benefits of these technologies, such as reduction in number of crashes, enhancing driver comfort or convenience, decreasing environmental impact, etc., are well accepted and endorsed by transportation safety researchers and federal transportation agencies. Even though these systems afford safety advantages, they challenge the traditional role of drivers in operating vehicles. Driver acceptance, therefore, is essential for the implementation of ADAS and semi-autonomous driving systems into the transportation system. These technologies will not achieve their potential if drivers do not accept them and use them in a sustainable and appropriate manner. The potential benefits of these in-vehicle assistive systems presents a strong need for research. A comprehensive review of current literature on the definitions of acceptance, acceptance modelling approaches, and assessment techniques was carried out to explore and summarize the different approaches adopted by previous researchers. The review identified three major research needs: a comprehensive evaluation of general technology acceptance models in the context of ADAS, development of an acceptance model specifically for ADAS and similar technologies, and development of an acceptance assessment questionnaire. Two studies were conducted to address these needs. In the first study, data collection was done using two approaches: a driving simulator approach and an online survey approach. In both approaches, participants were exposed to an ADAS and, based on their experience, responded to several survey questions to indicate their attitude toward using the ADAS and their perception of its usefulness, usability, reliability, etc. The results of the first study showed the utility of the general technology acceptance theories to model driver acceptance. A Unified Model of Driver Acceptance (UMDA) and two versions (a long version with 21 items and a short version with 13 items) of an acceptance assessment questionnaire were also developed, based on the results of the first study. The second was conducted to validate the findings of first study. The results of the second study found statistical evidence validating UMDA and the two versions of the acceptance assessment questionnaire.

Effect Of Cooking And Packaging Methods On Consumer Acceptability And Shelf-Life Of Ready-To-Eat Gulf Brown Shrimp

Kamadia, Vimal Vinodchandra 10 December 2010 (has links)
Shrimp is the most valued shellfish product in the United States, and is highly perishable with post mortem metabolic changes that are deteriorative to its shelf-life. The objective of this research was to utilize GC-MS Gas Chromatography-Mass Spectrometry (GC-MS), Gas Chromatography Olfactometry (GCO), and sensory analysis to determine if the relationships exist between consumer acceptability, sensory descriptors and shelf-life of ready-to-eat shrimp. Three different cooking and packaging treatments were utilized: 63°C/15 s, 85°C/5 min, and 93°C/5 min for vacuum, MAP and aerobic packaging treatments, and stored at 2°±1 for 1, 3, 5, 6, 10, 15, 25, and 50 days or until the product was found unacceptable by a trained sensory panel. For Consumer acceptability (Day 3), the 85°C vacuum and 85°C MAP (Modified Atmosphere Packaging) shrimp were preferred (P < 0.05) over other treatments that were evaluated. The aroma active compounds that were identified using GC-MS and GCO consisted of one amine (trimethylamine), five aldehydes (3-methyl butanal, pentanal, hexanal, heptenal, geranial), one organic acid (butyric acid), two sulfur containing compounds (methional, dimethyltrisulfide), one pyrazine (methyl pyrazine) (amine), two alcohols (2-nonen-1-ol, 4 ethyl guaiacol), and one hydrocarbon (camphene). Results showed that for most of the packaging-temperature combinations, even beyond Day 25, the MAP product had fewer compounds and odors associated with spoilage than the aerobic and vacuum packaged products. This was consistent with the descriptive analysis data for which both the 85°C MAP and 93°C MAP treatment products had a longer shelf-life than vacuum treatment products, which had shelf-lives of 15 to 21 Days. The shelf-life of the cooked RTE shrimp that was MAP packaged and cooked at either 85°C or 93°C was between 39 and 42 Days at 2°C. Research indicates that processors of medium gulf brown shrimp could utilize 85°C/5min with MAP due to the shelf-life of the product and the elevated pleasantness scores when compared to the 93°C/5min treatment throughout the shelf-life of the product.

Effects of Preblending and Water Addition on Physical and Sensory Characteristics of Seasoned Pork Patties

Field, Molly Sheppard 15 December 2012 (has links)
The objective of this study was to establish the consumer acceptability of preblended and nonpreblended post rigor seasoned pork patties with added water levels of 0, 3, 6, and 9 percent for each formula. Other parameters measured were proximate analysis, texture, cooking loss, and consumer acceptability. Nonpreblended treatments had a higher (P<0.05) percentage of protein and a lower (P<0.05) percentage of fat as compared to preblended treatments. Texture analysis revealed a lower (P<0.05) amount of total energy required to shear through a single patty in preblended treatments than nonpreblended treatments. No differences (P>0.05) were detected among treatments at varying water levels. Consumer acceptability showed no differences (P>0.05) among selected treatments. Consumer acceptability scores indicated that consumers would consume both preblended and nonpreblended seasoned pork patties at varying water levels.

The Effects of Low Atmospheric Pressure and Electrical Stunning on the Instrumental and Sensory Quality of Broiler Breast Meat Deboned at 45 Minutes and 4 Hours Postmortem

Radhakrishnan, Vijayakumar 14 December 2013 (has links)
Low Atmospheric Pressure Stunning (LAPS) has recently become available to the broiler industry. Therefore, research was conducted to determine the effect of stunning method (LAPS and Electrical Stunning(ES)) and postmortem deboning time (0.75 hr and 4 hr) on the instrumental and sensory acceptability (3 replications) of breast meat (n=576, 144 birds per treatment) prepared using different cooking methods (fried, baked, sous vide). Breast meat was evaluated for pH, CIE L*a*b*, yields, shear force, and consumer acceptability. Postmortem pH decline was more rapid (P<0.05) in the breast meat of LAPS stunned birds when compared to ES stunned birds, but no differences existed (P>0.05) among treatments with respect to final pH. On average, no differences (P > 0.05) existed in the sensory acceptability of fried and sous vide cooked broiler breast treatments. However, for the baked cooking method, the LAPS treatment that was deboned at 4 hr was more acceptable (P<0.05) than other treatments and the ES and LAPS 4 hr postmortem treatments had more acceptable (P<0.05) texture than the ES and LAPS 0.75 hr treatments. Since consumers were highly variable in their liking of chicken breast treatments, consumers were grouped into 6 clusters for each cooking method based on liking and preference. Cluster analysis data revealed that the greatest number of consumers liked all chicken breast treatments, but a larger proportion of consumers liked the 4 hour LAPS and ES treatments when compared to the 0.75 hr LAPS and ES treatments for all cooking methods. In addition, the consumers that indicated that baked chicken breast was highly acceptable preferred (P<0.05) breast meat from the 4 hr LAPS treatment over chicken breast meat from the 4 hr ES treatment. Based on sensory results, chicken breast meat from all stunning and deboning method combinations was highly acceptable to the majority of consumers, but the LAPS 4 hr treatment was slightly more acceptable than other treatments when baked.

Students’ acceptance to teacher interventions in the EFL classroom

Ahlner, Boel, Henriksson Thorsén, Emma January 2013 (has links)
The aim of this paper is to investigate EFL (English as a Foreign Language) students’ acceptance of teacher interventions to disruptive behavior in the classroom. As a method, qualitative research was conducted, including a collection of qualitative and quantitative data through a questionnaire, as well as a qualitative analysis. The respondents to the questionnaire were grade 7-9 students, located in the southern part of Sweden. The results indicate that the two interventions which both research and the study’s participants accepted, were Shorter recess and Quiet reprimand. Further, the interventions which research and the respondents somewhat agreed on, were Ignore, Stare, Approach and Parents/principal. Lastly, the two interventions which research and the participants disagreed on, were Stop it and Other room. There is a need for more research on students’ acceptance of interventions; therefore, we recommend future researchers to investigate it further.

A Consumer Perspective on Reshoring Production: Insights from Sweden

Hedin, Madeliene, Liang, Yajun, Gustaf, Witt January 2023 (has links)
Background: Reshoring refers to the process of bringing back manufacturing activities from foreign countries to the home country. The phenomenon is receiving increasing attention from companies and academics for factors such as increasing labor costs in offshore locations, supply chain disruptions, and a growing preference for locally made products. Sweden is home to many world-renowned multinational companies and multinational brands, many of which have established production operations in developing countries. However, reshoring from a consumer-side perspective has not received much research attention, especially from a Swedish consumer perspective. Purpose: This study investigates factors influencing Swedish consumers’ purchase intention on reshored products. This study focuses on five factors: brand attitude, social acceptability, individual ethnocentrism, made-in effect, and perceived social responsibility.  Methodology: This study adopts a quantitative research design and conducts a questionnaire regarding reshored apparel among Swedish consumers to test hypotheses. The data was collected through a web-based survey that 151 respondents answered. Findings: The empirical results indicate that brand attitude, social acceptability, and perceived social responsibility positively affect Swedish consumers' purchase intention on reshored apparel, while individual ethnocentrism and made-in effect do not have any significant effect.  Contributions: This study contributes to a deeper understanding of the implications of reshoring from a demand-side perspective, complementing the reshoring literature that primarily focuses on the business perspective. As the study is limited to a Swedish context, it provides a deeper understanding of Swedish consumers and their influence on reshored products.

The Relation of the Expression of Offense to Forgiving

Hall, Laura Grace 17 November 2010 (has links) (PDF)
Forgiveness is an essential component of relationship growth and healing, with academic, professional, and public interest in research and writing on the topic continually increasing over the past two decades. Indignation is endemic to interpersonal offense, and a key component of the forgiveness process; few, however, have written about the potentially facilitative role that it may play. Disparate conceptualizations of indignation among researchers and therapists may impede therapeutic progress, individually and interpersonally. This study presents a review of social science literature on forgiveness and a new model of the emotional response to offense that positions corrective, protective indignation on a continuum between two contrasting manifestations of destructive anger that reflect distortions in underlying views of self, other, and relationship. The study also includes the results of a statistical analysis of the Indignation and Forgiveness Scale (IFS) administered to a group of relational therapists (N = 98) gauging their professional judgment of the acceptability of indignation as a component of forgiveness as a facilitative emotion in the overall process of forgiveness. Overall, therapists expressed a strong belief in the compatibility of indignation and forgiveness. As a psychometric instrument, the IFS displayed multidimensionality, with items loading onto four subscales. Of the demographic characteristics, only the number of hours therapists' worked per week affected their views on indignation and forgiveness, with greater professional involvement leading to more favorable views of indignation in therapy for infidelity. Professional interest combined with a lack of theoretical and practical literature on these topics indicates that marriage therapists and scholars are prepared for continued research and model development on the role of constructive indignation in forgiveness.

Treatment Acceptabilty Of Teachers Of Adolescents By Level Of Intervention Intrusiveness And Type Of Disorder

Graves, Sarah E 15 December 2007 (has links)
The purpose of the current study was to examine the treatment acceptability ratings of teachers of adolescents on three different types of commonly used interventions: (a) positive verbal praise, (b) token economy with response cost and extinction, and (c) psychotropic medication. Ratings of treatment acceptability were also assessed according to type of disorder (i.e., externalizing or internalizing). The participants were 101 teachers of adolescents recruited from a midwestern public school district. Participants were asked to read two case studies presented in a counterbalanced format. One case study focused on a youth who displayed symptoms related to an internalizing disorder (Major Depressive Disorder), while the other focused on a youth who displayed symptoms of an externalizing disorder (Conduct Disorder). After each case study, participants were asked to read three treatment vignettes. Each treatment vignette described one of the three previously mentioned interventions. The participants then rated the treatment acceptability of each intervention using a modified Abbreviated Acceptability Rating Profile. A 2 x 3 repeated measures ANOVA was used to analyze the data from the measures. Statistically significant differences were found among level of intervention intrusiveness, type of disorder, as well as interaction effects between the two main variables of interest. Overall, teachers indicated they found less intrusive interventions as more acceptable than the more intrusive interventions; interventions for externalizing disorders were also rated as more acceptable than interventions targeting internalizing disorders. A noteworthy exception was the most intrusive intervention, psychotropic medication, as equally acceptable for both disorders. The current study is unique in that previous researchers have not investigated treatment acceptability of internalizing disorders or among teachers of adolescents as a population. The findings of this study may be useful for teachers of adolescents experiencing classroom difficulties with youth displaying symptoms of either Conduct Disorder or Major Depressive Disorder. Recommendations for future research are discussed as well.
