The purpose of this study is to assess the quality of services by using the integration of Servqual and the Kano model. In this study, Servqual is used to determine the quality criteria that must be improved. At this method, the quality criteria are based on the gap that occurs between differences in perceptions and expectation of customers for the services they receive. Meanwhile, the Kano method is used to categorize service attributes that satisfy customer needs. Servqual integration and the Kano model were carried out by synchronizing the Servqual gap value and the Kano model grade. Assessment of service attributes obtained from both methods produces service attributes that will be the focus of management's improvement to improve service quality. The results showed that the attribute criteria that must be prioritized were attributes that included attractive and one-dimensional categories which had the highest negative gap value. Improvements in attributes in attractive and one-dimensional categories will improve service quality and increase customer satisfaction.

Three different studies have discussed regulations ofthe assessment of user satisfaction levelswith terminal services. Based on the assumption that the terminal attributes derived from regulations are accurate, this study aims to analyze the content of the regulations, compare them, and analyzeterminal user satisfaction as assessed by previous studies. Content analysis of the literature is conducted. The results reveal that among the user satisfaction survey regulations from the Minister of Administrative and Bureaucratic Reform Regulations of 16/2014 and 25/2004 and the service standard regulations from the Minister of Transportation Regulation of 40/2015, the most feasible regulation for the assessment of user satisfaction is the Minister of Transportation Regulation of 40/2015. This regulation does not regulate satisfaction assessment but can be used as a basis for assessments of user satisfaction with terminal services. All of the stipulated service standards can be classified as accurate terminal service attributes. Therefore, improvements can be made by including a requirement for satisfaction assessments. Through the incorporation of the service quality concept, such improvement could establish this regulation as a basis for reputable studies of satisfaction assessments. Another result reveals that the literature on the assessment of terminal user satisfaction based on the Minister of Transportation Regulation of 40/2015 reports that users are satisfiedwith the terminal attributes of reliability, convenience, affordability and equity, but they are unsatisfied with the attributes ofsafety and security. Thus,terminals should implement maximal regulation of service standards. Assurance of terminal securitycould increase user satisfaction.

Assessment of public satisfaction with an agency's performance that organizes public services needs to be assessed by involving all service attributes because service attributes cannot stand alone, and performance improvement cannot be made separately. Assessment of service attributes is one way to track consumer ratings so that service providers can understand the causes of service problems. This study uses the Importance Performance Analysis (IPA) method. From this study, it was found that the priority that needs to be improved to improve public satisfaction with population administration services is to increase the discipline of officers in serving the community, certainty of service costs, and speed of service.

This study aims to determine the sanitation conditions of buildings and cleaning facilities at an Environmental Services Company. In this research, the Importance Performance Analysis (IPA) mapping of each attribute of the assessment of the sanitation condition was evaluated so that it can be seen which assessment attributes have low values and need to be assessed to get corrective action as a top priority. This research is descriptive quantitative research by collecting data through direct observation and distributing questionnaires to all employees of the Environmental Services Company. The results of 20 respondents were processed using the SPSS 16 application. The results showed that the sanitation conditions of the buildings and cleaning facilities at the Environmental Service Company did not meet the requirements. Priority mapping of the sanitation attributes of buildings and cleaning facilities using the Importance Performance Analysis (IPA) method can be seen in the Cartesian diagram. The result shows that from all 17 building sanitation attributes, there are 3 attributes in quadrant A. While 7 attributes are in quadrant B, 3 attributes are in quadrant C, and 3 attributes are in quadrant D. Of the 46 sanitation attributes for sanitation facilities, there are 8 attributes in quadrant A, 24 attributes in quadrant B, 13 attributes in quadrant C, and 1 attribute in quadrant D. Attributes that have low scores on building sanitation, namely the yard and roof of the building, while in sanitation of cleaning facilities, namely lockers in the changing room, trash cans, and sanitary napkins.

The benchmark for the success of a business or product is to measure the satisfaction of customers who have used or felt the goods or services. The customer's expectations of the function and emotional happiness factors that arise from the use of goods or services are entirely the responsibility of the producer. So that manufacturers need to focus on what attributes must be presented in a product or service to increase customer satisfaction. The decrease in customer interest in providing vehicle service at an automotive company in Sidoarjo is the problem studied in this study, to analyze the level of customer satisfaction and attributes that are priority improvements as recommendations for the company.
Data generated from customers is processed and analyzed using the Service Performance (SERVPERF) and Lean Service methods. Based on the results of data processing, it can be concluded that the level of customer satisfaction with service quality is 82.3%, and three service attributes are classified as a top priority and two types of critical waste.

App-based demand-responsive transit (DRT) services are emerging where conventional public transport is unable to meet the demand. SWVL (choice A) and Airlift (choice B) are two such DRT bus services operating in Lahore, Pakistan. It is important for the policy makers and operators to evaluate the satisfaction levels of the passengers using these services. This study evaluated passengers’ satisfaction regarding choice A and choice B through a questionnaire survey. A total of 440 responses were collected from the users of the DRT services through personal interviews and a web-based approach. Factor analysis on the collected data produced two underlying factors, namely service-attributes and bus ambiance. Ordinal regression showed that the service-attributes and ambiance were significant predictors of overall satisfaction levels about choice A. Service-attributes indicated a larger positive impact on overall satisfaction with choice A as compared to ambiance. Although the ordinal model for choice B fitted the data well, the predictors were found to be insignificant. The results offer an insight into which predictors affect the overall satisfaction and how it can be improved.

The effects of attribute performance on satisfaction have been widely addressed in the discussion on satisfaction. In traditional view, customer satisfaction should be enhanced by improving product or service attribute performance. However, as theoretical and empirical studies have shown, the linkage between attribute performance and overall satisfaction is asymmetric and nonlinear, which means that it is not a definite relationship between high performance of attribute and satisfaction. Regarding the research on delivering asymmetric effects, the Kano model was utilized extensively in the previous studies. But this method suffers from lacking a validity testing and failing to take account of the degree of attribute’s importance. To get a more effective access to measuring the asymmetric and nonlinear effects of attributes on customer satisfaction, this study presents an integrated approach which can express asymmetric effects through evaluating the significance of different attributes to satisfaction based on response surface analysis and importance grid analysis methods. In this paper, an empirical study on rural tourists’ satisfaction was undertaken using this integrated method. Furthermore, compared with the regression with a dummy variable method, this proposed approach shows more responsive to enhancing attribute performance and makes allowance for improving a certain target attribute in the customer satisfaction improvement process.

Although the past research results have provided many effective tools for evaluating public bus service quality, they still lack the concept of risk. This study assessed the quality risk for city bus service by constructing a quality risk assessment model that integrated Kano’s model, IPA, and FMEA. The online questionnaire was distributed to commuters who use BMTA’s bus service in Bangkok with 429 samples. This study analyzed the service quality attributes of bus services via Kano’s model, an IPA, and an FMEA. For the results of Kano’s model, this study identified nine one-dimensional and three attractive attributes. The results of the IPA showed that the safety of boarding and disembarking from the bus, the cleanliness of vehicles, and the punctuality of buses according to the schedule were the top three attributes that had a large gap between importance and satisfaction. According to the results of the FMEA, the safety of boarding and disembarking from the bus, the cleanliness of vehicles, and the punctuality of buses according to the schedule were the top three attributes that had a high service quality risk and considered a priority improvement. These attributes belonged to interaction with passengers, tangible service equipment, and operating management support dimensions. Therefore, the government should take action and improve service quality to make Bangkok commuters consider switching from driving cars to using a bus. Finally, this study provides practical improvement strategies for managers to improve passenger experiences and enhance the quality of bus services.

PT. Telkom (Telekomunikasi Indonesia) is a state-owned enterprise that has an important contribution to society because it is engaged in telecommunications services. Indihome is one of the service products from PT. Telekomunikasi Indonesia, which provides packages of landline, internet, and television services. In an effort to provide information services, it is necessary to evaluate the performance of internet services so that the service provider is able to maintain performance and improve performance where there are still shortcomings in performance from the user's point of view. To determine the level of service performance, this research was carried out by applying the servqual method and Importance Performance Analysis. The assessment of user satisfaction is based on five dimensions, namely Reliability, Responsiveness, Assurance, Empathy and Tangibles which later on each attribute performance will be classified into quadrant I which is the main priority to improve its service, quadra II attributes that need to be maintained because they have provided satisfactory service, quadrant III attributes that have low priority and quadrant IV attributes that are considered less important but have good performance. The results of this study indicate that the largest gap or gap lies in the Responsiveness dimension with a value of -1.00 and the smallest gap in the Empathy dimension with a value of -0.43. while based on the calculation of the Importance Performance Analysis the overall user suitability level is 83% which means that the services provided by the agency/company are in accordance with the user's perception.

The development of the Internet and World Wide Web have led to many services being offered electronically. When there is sufficient demand from consumers for a certain service, multiple providers may exist, each offering identical service functionality but with varying qualities. It is desirable therefore that we are able to assess the quality of a service (QoS), so that service consumers can be given additional guidance in se lecting their preferred services. Various methods have been proposed to assess QoS using the data collected by monitoring tools, but they do not deal with multiple QoS attributes adequately. Typically these methods assume that the quality of a service may be assessed by first assessing the quality level delivered by each of its attributes individ ually, and then aggregating these in some way to give an overall verdict for the service. These methods, however, do not consider interaction among the multiple attributes of a service when some packaging of qualities exist (i.e. multiple levels of quality over multiple attributes for the same service). In this thesis, we propose a method that can give a better prediction in assessing QoS over multiple attributes, especially when the qualities of these attributes are monitored asynchronously. We do so by assessing QoS attributes collectively rather than indi vidually and employ a k nearest neighbour based technique to deal with asynchronous data. To quantify the confidence of a QoS assessment, we present a probabilistic model that integrates two reliability measures: the number of QoS data items used in the as sessment and the variation of data in this dataset. Our empirical evaluation shows that the new method is able to give a better prediction over multiple attributes, and thus provides better guidance for consumers in selecting their preferred services than the existing methods do.

Further, since the Kano Model was initially developed more than 20 years ago in 1984 with a focus on manufacturing and durable goods, this study introduces a Modified Kano Model that may be better suited for evaluation of attributes related to services. In the Modified Kano Model, the attributes of the original Kano Model (Attractive Quality, One-Dimensional Quality, Must-be Quality, Reverse Quality, and Indifferent Quality) have been modified to better reflect the intangibility and other distinctive characteristics of services. The revised attribute categories have been titled as Desirable Attributes, Positive Attributes, Critical Attributes, Negative Attributes, and Zone of Indifference. The study also provides an extensive discussion of conjoint analysis techniques, historical evolution, and a review of application of conjoint analysis across various industries; including research within and beyond the hospitality industry. Essentially this study delivers a primer on conjoint methodology. Related to the conjoint analysis components for this research, this study employs Sawtooth Software as the platform for the web-based questionnaire, as well as the data analysis. Sawtooth Software's products are the most widely used conjoint analysis systems in the world providing a variety of solutions from traditional full profile conjoint analysis to more advanced adaptive choice conjoint analysis techniques. This study employs the Choice-Based Conjoint technique; one of the most commonly used techniques in academic research. Choice-based conjoint provides respondents a series of set choices from which they express preferences for specific attribute combinations. Choice-based conjoint analysis is widely used due to its ability to simulate consumer behavior in the marketplace more precisely.; Specifically, the following attributes were categorized by the respondents as being positively related to their product satisfaction: 1) a sales executive to guide the prospective purchaser through the sales process, 2) a purchase incentive, 3) resort-like hotel services, i.e., concierge, 4) affiliation with an exchange company, 5) resort amenities, i.e., fitness center, 6) ability to trade for hotel program benefits, and 7) a vacation counselor to assist with vacation planning. In the Modified Kano Model they are described as Positive Attributes based on the relationship to product satisfaction. Perhaps equally as important as understanding the positive effect of attributes is understanding which attributes have no incremental effect on product satisfaction. In this study, the majority of the respondents categorized the availability of a finance package and the presence of onsite activities as attributes that neither added to their satisfaction or dissatisfaction with the product. These attributes are termed as Zone of Indifference in the Modified Kano Model since they neither add to nor detract from overall product satisfaction. In an effort to quantify consumer preference for particular attributes, this study employed conjoint analysis to test the presence/absence of the study attributes in a series of simulations. Two fixed choice sets and a "none option" were also employed to improve the reliability of the results. The result of the conjoint simulation revealed that willingness to pay for the vacation ownership product varied based on product features, and it also varied across respondents. Possibly the most imperative outcome of this research is that this study uncovered attribute preferences that have a significant influence on satisfaction or price paid for the vacation ownership product.; The findings of the research were consistent with previous literature in that it was found that attributes of the product could be classified using the Modified Kano Model, and that consumers are satisfied with the product purchased. However, this research goes beyond previous studies in that it specifies the anticipated effect on satisfaction and consumer willingness to pay at the attribute level for both the purchase and use of the vacation ownership product. Further, while this research identified that consumers' basic needs are being met and the industry is delivering on expectations related to attributes that contribute to overall satisfaction, it also uncovered opportunities for product development and pricing strategies that may assist in attracting new customers and expanding the vacation ownership segment of the lodging industry. In addition to an explicit discussion of the results, this dissertation provides specific practical implications based on the findings. This research could be considered unique as it is a comprehensive view into customer satisfaction and willingness to pay related to both the purchase and the consumption of a vacation product. As a result, an additional contribution could be the establishment of a benchmark for future studies.; The ongoing pursuit of understanding how consumers' expectations can be achieved or exceeded has long been an area of interest for academics and practitioners alike. A multitude of measures of satisfaction have been developed, applied, and adopted with the end goal of understanding how satisfied individuals, or groups of individuals, are with a given product, service, or specific attribute of a product. And, while both academic and practical research has identified and focused on explicit attributes relevant to particular products or services, the general consensus appears to support the thinking that higher satisfaction is better. But this may not hold true when one considers that not all attributes are equal in terms of their effect on overall customer satisfaction or that different customer segments may value product attributes differently. From this premise, the current research proposes a model that may be used to classify product and process attributes within the services industry, and augments the traditional method of data analysis in an effort to improve the efficacy of the information gathered. The theoretical foundation of the study is based on a modified Kano Model, a research model that has been widely applied across a variety of industries and products. Responses from 3,231 consumers were collected in a nationwide survey conducted in the United States. A random sampling method was used with the intention of achieving sufficient heterogeneity among the study participants. This study provides a comprehensive review of literature related to the Kano Model that has also been summarized in a tabular form (Table 3), providing the readers with a robust synthesis of literature (1984-2010) to include authors, publication dates, sources, titles, research contexts, etc.; Through the use of the Modified Kano Model and choice-based conjoint analysis, this study assessed the role of process and product attributes in consumers' willingness to pay for and utilize products in the vacation ownership industry. The current study has identified product and process attributes that are preferred by the customer, categorized the attributes according to their anticipated effect on customer satisfaction, and quantified customer preferences of each in order to establish customer attribute preferences within the vacation ownership industry. In a two-pronged approach, this study explored two distinct aspects of the consumer's vacation ownership experience: the purchase process and the use of the lodging product. Since it has been shown that the Kano Model is effective in categorizing attributes according to the anticipated effect on customer satisfaction in a manufacturing environment, a modified version of this model was extended to a service sector, the vacation ownership industry. This Modified Kano Model was used to determine consumers' preferences for the vacation ownership product during its use, as well as throughout the purchase process. In addition, the Kano methodology was augmented through the use of Fong's test of statistical significance and Conjoint Analysis in an effort to improve the quality of the information gathered, and advance the efficiency and applicability of the instrument. This study identified attributes of the vacation ownership product that are positively related to customer satisfaction.ID: 030422774; System requirements: World Wide Web browser and PDF reader.; Mode of access: World Wide Web.; 39] pages in Appendix B are unnumbered.; Thesis (Ph.D.)--University of Central Florida, 2011.; Includes bibliographical references (p. 135-147).

The emergence of ePortfolios is relatively recent in the university sector as a way to engage students in their learning and assessment, and to produce records of their accomplishments. An ePortfolio is an online tool that students can utilise to record, catalogue, retrieve and present reflections and artefacts that support and demonstrate the development of graduate students’ capabilities and professional standards across university courses. The ePortfolio is therefore considered as both process and product. Although ePortfolios show promise as a useful tool and their uptake has grown, they are not yet a mainstream higher education technology. To date, the emphasis has been on investigating their potential to support the multiple purposes of learning, assessment and employability, but less is known about whether and how students engage with ePortfolios in the university setting.
This thesis investigates student engagement with an ePortfolio in one university. As the educational designer for the ePortfolio project at the University, I was uniquely positioned as a researching professional to undertake an inquiry into whether students were engaging with the ePortfolio. The participants in this study were a cohort (defined by enrolment in a unit of study) of second and third year education students (n=105) enrolled in a four year Bachelor of Education degree. The students were introduced to the ePortfolio in an introductory lecture and a hands-on workshop in a computer laboratory. They were subsequently required to complete a compulsory assessment task – a critical reflection - using the ePortfolio. Following that, engagement with the ePortfolio was voluntary.
A single case study approach arising from an interpretivist paradigm directed the methodological approach and research design for this study. The study investigated the participants’ own accounts of their experiences with the ePortfolio, including how and when they engaged with the ePortfolio and the factors that impacted on their engagement. Data collection methods consisted of an attitude survey, student interviews, document collection, a researcher reflective journal and researcher observations.
The findings of the study show that, while the students were encouraged to use the ePortfolio as a learning and employability tool, most students ultimately chose to disengage after completing the assessment task. Only six of the forty-five students (13%) who completed the research survey had used the ePortfolio in a sustained manner. The data obtained from the students during this research has provided insight into reasons why they disengaged from the ePortfolio. The findings add to the understandings and descriptions of student engagement with technology, and more broadly, advance the understanding of ePortfolios. These findings also contribute to the interdisciplinary field of technology implementation.
There are three key outcomes from this study, a model of student engagement with technology, a set of criteria for the design of an ePortfolio, and a set of recommendations for effective practice for those implementing ePortfolios.
The first, the Model of Student Engagement with Technology (MSET) (Version 2) explored student engagement with technology by highlighting key engagement decision points for students The model was initially conceptualised by building on work of previous research (Version 1), however, following data analysis a new model emerged, MSET (Version 2). The engagement decision points were identified as:
• Prior Knowledge and Experience, leading to imagined usefulness and imagined ease of use;
• Initial Supported Engagement, leading to supported experience of usefulness and supported ease of use;
• Initial Independent Engagement, leading to actual experience of independent usefulness and actual ease of use; and
• Ongoing Independent Engagement, leading to ongoing experience of usefulness and ongoing ease of use.
The Model of Student Engagement with Technology (MSET) goes beyond numerical figures of usage to demonstrate student engagement with an ePortfolio. The explanatory power of the model is based on the identification of the types of decisions that students make and when they make them during the engagement process. This model presents a greater depth of understanding student engagement than was previously available and has implications for the direction and timing of future implementation, and academic and student development activities.
The second key outcome from this study is a set of criteria for the re-conceptualisation of the University ePortfolio. The knowledge gained from this research has resulted in a new set of design criteria that focus on the student actions of writing reflections and adding artefacts. The process of using the ePortfolio is reconceptualised in terms of privileging student learning over administrative compliance. The focus of the ePortfolio is that the writing of critical reflections is the key function, not the selection of capabilities.
The third key outcome from this research consists of five recommendations for university practice that have arisen from this study. They are that, sustainable implementation is more often achieved through small steps building on one another; that a clear definition of the purpose of an ePortfolio is crucial for students and staff; that ePortfolio pedagogy should be the driving force not the technology; that the merit of the ePortfolio is fostered in students and staff; and finally, that supporting delayed task performance is crucial.
Students do not adopt an ePortfolio just because it is provided. While students must accept responsibility for their own engagement with the ePortfolio, the institution has to accept responsibility for providing the environment, and technical and pedagogical support to foster engagement. Ultimately, an ePortfolio should be considered as a joint venture between student and institution where strong returns on investment can be realised by both. It is acknowledged that the current implementation strategies for the ePortfolio are just the beginning of a much longer process. The real rewards for students, academics and the university lie in the future.

Among increasing needs of domain-aware computational models that can perform large-scale assessment like domain experts, the development of automatic oral presentation assessment system is important for education researchers. In this work, we extend the previous audiovisual framework on pre-service school principals’ 3-minute long impromptu speech using lexical information as additional modality. We aim at exploring effective feature set for text and enhancing the performance of lexical modality by manual tagging information. First, we utilize multi-level feature extraction approach, which consists of distributed representations and word categories, to derive features from the transcripts in the 2014 National Academy for Educational Research (NAER) oral presentation database, and improve the result of lexical modality from Spearman correlation of 0.378 to 0.493. Furthermore, inspired by folksonomy, we propose to enhance lexical feature by using a self-defined attribute tags of speech transcripts. Therefore, we carry out two different experiments: Exp I) considering the tags as other labels and employing multi-label learning, and Exp II) feature inspired by tags and topic modeling. After incorporating the two methods, the improved system obtains Spearman correlation of 0.574. Our experiment demonstrates the concept of self-defined attribute tags has capability to enrich lexical modality and improve system.

AbstractIn developing countries, where competing priorities often overwhelm capacity, the sweeping BEPS initiative can serve to motivate and justify the devotion of limited resources to the international tax field. It is hard to say whether all of the BEPS Actions are “suitable” for developing countries as their size, level of maturity, and many other factors that influence taxation vary drastically. An evaluation of domestic circumstances will help to determine the tax regime’s compatibility with the BEPS recommendations. This initiative represents a minimum level of commitment that is necessary to ascertain sustainable BEPS implementation. Certain attributes will influence the feasibility of this implementation such as the adaptability of the juridical system to enforce new regulations, the technological infrastructure, the capacity to process and protect mass information, efficient risk assessment procedures and analysis tools, and continual training and development workshops, among others. The BEPS project is still quite young; however, thanks to contributions from CIAT member countries, the BEPS Monitoring database was created. This can provide us with a general overview of how extensively each BEPS Action has been implemented in these countries so far.

An analysis of the subjects, the procedure and time limits for appealing to a court of civil jurisdiction with a complaint against the decision, action or inaction of a state executor or other official of a state executive service body or a private executor was carried out, and the procedure for consideration of relevant complaints in the civil court procedure was regarded, as well as the procedural form was studied resolution of this issue by the court. The problem of demarcating the jurisdiction of courts regarding the resolution of such categories of cases was studied, in particular, when appealing the decisions of the state executor on the collection of the enforcement fee and the private executor on the collection of the main fee, their decisions on the collection of costs of enforcement proceedings and fines; when filing complaints about decisions, action, inaction in the execution of decisions of non-judicial bodies and other officials, as well as when appealing decisions, actions of inaction in summary executive proceedings and appealing reports of subjects of assessment activity.It is summarized that such an option, which involves determining the jurisdiction of the court precisely by the type of executive document, taking into account which court or other body (official) it was issued, is the most optimal, because all other procedural issues that arise during the execution of the decision in the majority cases are decided according to this criterion. In particular, as we noted at the beginning, this rule should apply to all subjects of enforcement proceedings, and not to further demarcate jurisdiction based on their status. In addition, we do not even consider it expedient to attribute to the competence of administrative courts not only the consideration of complaints against the decisions of the state executor on the collection of the executive fee and the private executor on the collection of the basic remuneration, their decisions on the collection of the costs of the executive proceedings and fines, but also complaints about the decisions, actions, inaction in the execution of decisions of non-judicial bodies and other officials, since a court of civil jurisdiction is also involved in the execution of certain procedural issues. In view of this, it is justified to use a unified approach in all situations related to the enforcement of the decision of the same body or official, and at the same time apply for their settlement to the same court.

Web services provide a fundamental technology for developing service-oriented systems by leveraging platform-independent interface descriptions (WSDL) and a flexible message encoding (SOAP). Beside the functional description, Quality of Service (QoS) issues are currently not part of the Web service standards stack, although they provide valuable metadata of a Web service such as performance, dependability, security or cost and payment. This additional information can be used to greatly enhance service discovery, selection and composition. As a result of the latest research that is dedicated to this area, this chapter deals with the various ways of describing, bootstrapping and evaluating QoS attributes. A strong focus is laid on client-side QoS assessment and the arising problems. Furthermore, a method to analyze Web service interactions by using our evaluation tool and extract important QoS information without any knowledge about the service implementation will be presented and thoroughly explained. Usually, taking performance measures for a specific Web service requires access to the service implementation or at least the server machine where it is hosted. This chapter will address a way to bootstrap the most important performance and dependability values form the client’s perspective and therefore overcoming these restrictions.

This study compares the online services currently delivered by the official National Tourism Organizations (NTO) portals of the 25 European Union states, to assess their capability in evolving into powerful marketing communication tools. A conceptual framework that identifies 129 online service quality attributes is developed based on the 2QCV3Q model (Mich et al., 2003) and on four different perspectives: marketing, customer, technical and information for the destination (So and Morrison, 2004). The 25 portals are compared by means of content analysis. Our rankings provide a first time assessment of the NTO online offerings and indicate high variability in their performance. Surprisingly, Greece and Italy, two of the most popular tourism destinations, underperformed with respect to all four perspectives examined. We provide out-of-sample evidence that affluence levels explain the variation in the observed scores, while e-readiness, popularity of tourism destination and cultural richness are not statistically significant.

Recent years have seen the rapid growth of on-demand, flexible, low-cost cloud-based information technology services. Government and business organizations around the world have started transforming their traditional in-house data center environments to cloud-based outsourced data centers. This transformation is opening doors to new risks given that the cloud computing delivery models, related services, and technologies are still maturing and evolving. Before deployment, organizations must implement cloud environment assessment methodologies to comply with the applicable standards and regulations. They must evaluate the environment’s quality attributes of Internet connectivity, user access control, privacy and confidentiality, asset protection, multiple platforms locality, availability, reliability, performance, and scalability. The purpose of this chapter is to assist organizations that are considering providing and consuming cloud-based services in developing an assessment plan specific to organizational policies, strategies and their business and applicable legal and regulatory requirements; and assessing the cloud environment controls for infrastructure, platform, and software services.

By enabling consumer products to be made on-demand and eliminating waste from overproduction and transport, online 3D printing service is more and more popular with unprofessional customers. As a growing number of 3D printers are becoming accessible on various online 3D printing service platforms, there raises the concern over online 3D printing service evaluation and selection for novices as well as users with 3D printing experience. In this paper, we analyze this problem using information transformation techniques and multinomial distribution probabilistic model. Evaluation factors, the major attributes that significantly affect the performance of an online 3D printing service, are described with standard description form. Meanwhile, historical service data is introduced to identify and update these evaluation factor values. Based on these parameters, evaluation and comparison can be implemented upon online 3D printing services using the probabilistic model. An example is presented to illustrate the assessment process based on the proposed evaluation model. The presented objective probabilistic evaluation method can serve as the basis of online 3D printing service evaluation and selection on an online 3D printing service platform. Although the focus of the work was on 3D printing service, the idea can be applied to other online rapid prototyping sharing systems.

Unlike the circumstance associated with transmission pipelines, where variables that are attributes of risk are typically widely available in GIS systems or in other databases that are geo-referenced to linear assets, risk data for distribution systems are not typically linearly referenced to what is essentially a network system. Therefore the manner in which risk is calculated and displayed for distribution systems must differ significantly from the way these functions are performed on transmission pipelines. In distribution systems, failure (defined as the loss of containment) and the contributors to the likelihood of failure, is often highly correlated to system-specific circumstances, such as type of material used, installation era, and operating environment. These correlations between cause-and-effect as they relate to failure likelihood in distribution systems are not widely recognized on a universal basis, such as they might be in transmission pipeline environments, but are typically unique to each operating system. Because system data for distribution networks is not typically available in a manner that can be linearly geo-referenced to pipeline coordinates the way it is for transmission systems, the convention of mapping risk to pipeline dynamic segments as a function of risk attributes that exist within those dynamic segments is not achievable for distribution systems the way that it is for transmission systems. Therefore, the most effective strategy for performing risk assessments in distribution systems is to create a database in which existing incident data can be correlated to system attributes, and then to use those correlations to create cause-and-effect relationships between system attributes and failure likelihood. Consequences are characterized in terms of the operating environment (e.g., wall-to-wall, residential, etc.), leak magnitude, type of facility (mains vs. service lines), and special mitigating or exacerbating factors, such as availability of excess flow valves, or the presence of inside meters. A risk assessment methodology has been developed that accommodates the above constraints and that meets the stated objectives, and which is well-suited to the distribution system data infrastructure that is typical of most operators. Because the risk assessment approach leverages existing databases and incident reporting structures, it lends itself to automation, and re-evaluation on a regular basis. Reporting is facilitated by a ‘heat map’, which provides immediate insight as to the drivers of risk for each system sub-group having similar design, materials, and operating characteristics.

Abstract The 7th generation semi-submersible drilling units (CSDU) are characteristic of deeper drilling depth, site locations and higher operational efficiency, compared with the last generation ones. Given the enormous live loads change and increasing trend of main size dimensions, considerable optimization should be deployed to achieve a balance of economy, safety and good work performance. Trial calculation and definite assessment to check whether alternative schemes meet the requirements turns out to be ineffective, for the case by case study of hydrodynamic and structure strength analysis is time consuming. In the paper, an integrated optimal design model is formulated by merging multi-objective optimization and multi-attribute decision making into one. A predesigned parametric Finite Element Analysis (FEA) structural model of CSDU is developed and validated and then coupled with detailed hydrodynamic analysis. Three mutually conflicting design objectives are arrived by hydrodynamic solutions. They are stability, hydrodynamic performance and steel consumption, which are screened to obtain Pareto optimality. The Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) is applied to incorporate these optimal attributes into decision-making process, considering all criteria in terms of quantitative stability, hydrodynamic performance and qualitative economy. The objective entropy coefficient measuring the importance of different attributes is introduced into weight selection for the purpose of avoiding non-determinacy and optional judgements. The optimal solutions are further verified with main dimensions of CSDUs in service and also could give predictive suggestion for the new CSDUs. The study provides a more objective way of benchmarking different structural schemes of CSDU by considering multiple criteria simultaneously. It is demonstrated that the proposed structural optimization model is capable of effectively and accurately determining the optimal design of CSDU.

Abstract Alternating temperatures induce thermomechanical stresses in thick-walled components such as turbine rotors or housings, which can lead to fatigue and superimposed creep. Subsequently, damage can occur at their heated surfaces. Under the nowadays prevailing operating conditions of power plants with multiple cold, warm and hot starts as reaction to the high volatility of electric demand from fossil fired power plants for ensuring grid stability, methods for lifetime assessment are coming more into the focus of investigations and research. Engineers are trying to estimate the residual lifetimes of in-service components and operators of power plants ask for strategies to minimize the calculative material damage while simultaneously providing a maximum flexibility with shortest response times on altered demands. Among constitutive models, which are not subject of this paper, accumulative models for lifetime assessment were introduced several decades ago and are partially considered in applicable standards. Such models based on a damage accumulation are easy to apply but they are considered to be either very imprecise or very conservative, while the conservatism reflects the necessity of large safety margins. This paper summarize a few measures, which are suitable to improve the predictive quality of models based on a simple time-fraction rule. The proposed model is based on a synthesis of hysteresis loops for isothermal and non-isothermal conditions, concepts for consideration of cyclic softening or hardening during lifetime, concepts for dealing with internal back stresses, mean strains or stresses, and for accounting of creep-fatigue interaction. The latter is based on a so-called transition time concept, where the creep damage during dwell times partially attributes to the portion of fatigue damage, which in turn is determined from fatigue life curves for dwell time experiments. In addition, the model comprises a concept for the post-processing of transient FEM calculations and dealing with multiaxial loading conditions. Since the essentials of the proposed method with the transition time concept were published more than 10 years ago, the listed modifications improve the benefit for daily engineering usage. Validation experiments provide evidence of the models predicting capabilities with acceptable uncertainty.

Geologic hazards pose a significant threat to pipeline integrity. As an existing pipeline system ages, targeted analysis and positioning of maintenance resources become increasingly important to remediating problem pipeline sections and to ensure timely response to system failures. A geographic information system (GIS) now is commonly used to model pipeline systems. Significant geologic hazards can be mapped and effectively managed in a GIS database as a way to assess risk and to target pipeline remediation resources. In particular, the potential for soil corrosion is a significant threat to pipelines. In the U.S., digital soil maps from the United States Department of Agriculture, Natural Resources Conservation Service (USDA NRCS) have been compiled into the Soil Survey Geographic (SSURGO) database. Numerous soil attributes are stored in the database allowing for a detailed examination of soil characteristics. SSURGO data is largely consistent in quality and geographic extent across the U.S. and is the best available database for a national assessment of soil corrosion potential. We describe the development of a national database for the collection of locations of known corrosion from pipeline system managers. This database can be compared to soil conditions, as noted in SSURGO or other supporting soil data, for the development of a model of soil parameters that may indicate the future potential for buried pipeline corrosion. This paper outlines the need for such a database, significant design considerations and the proposed process for model development.

Current assessment and progression policies and practices in higher education are largely dominated by dichotomy between formative and summative assessments. Given assessments are major drivers of learning, such as dichotomous assessment systems which promote the learning that can only be tested via summative assessments and falls short in fostering complex graduate attributes - such as interdisciplinary competencies. Medical programs, across the globe are now embracing emerging concepts such as programmatic assessment that allows the assessments to serve ‘for, of and as’ learning. Given the most challenging curricular reform in any field, including Business is reforming assessments, this paper critically reflects on how emerging concepts such as programmatic assessment are promising in resolving the tensions created by dichotomy of assessment for vs as learning. The reflections are based on rapid scoping review of programmatic assessment in Medical education, as well as authors’ familiarity with implementation of programmatic assessment in the Sydney Medical School renewed curriculum. There are many lessons that can be learned and carried over from the University of Sydney Medical curriculum to the Business education space.

Abstract Engineering Asset Management(EAM) is management of engineering assets and it provides guidelines on the effective usage of all the physical engineered assets within the organization. Similarly, Non-Destructive Testing [NDT] is used as a handy tool for integrity assessment of Assets in scheduled maintenance & inspection program. Though Asset Inspection in Oil & Gas Industry were using conventional NDT methods, now ASME, API and others came up with inspection procedures based on fracture mechanics, where each user to ascertain how their tool/regional operating condition deviate from the assumptions herein, then employ their engineering and technical judgment in deciding how and when to employ any part of these standard. Till recent past, there were no regular validation for these procedures being performed as presumed; benchmark for Severity of failure in North Sea offshore and that in MENA Onshore are set as same. Integration of Operations Management System [OMS] based in Asset Inspection with the EAM allows the Asset Owner/Custodian to consistently monitor each Asset, Acquire monitoring / measurement data in common platform using standardized operating procedures, Measure / Analyze Longevity of each Asset and enable the end user to validate their Service Quality Plan and inspection procedures, as per applicable operating limits and risks. The purpose of this paper to emphasize the importance of optimizing the Asset utilization and serviceability to enhance overall efficiency by integrating; (1)EAM software that manages Assets, (2)OMS controlling the process and (3)Asset Inspection Management System[AIMS]. Case study refer our AIMS, a tool to track all Equipment data [Images, OEM/CoC Document, Inspection Reports/Certificates, track analysis of major attributes] through a single channel - Master Asset [Inspection] Register. Uniquely numbered Assets in each category Drilling Tubulars, Hosting &Handling Equipment and/or Lifting Equipment Item is captured in respective Master Asset Inspection Register with all related Equipment data & Inspection records. Inspection records provides all its inspection related history since its commissioning and manufacturing OEM/CoC Documents. Our cloud based AIMS-App's compliance to API Q2, ISO9001:2015 and ISO17020:2012 ensures its certifying requirements to, (1)relevant Industry standard and bench mark (2)Competence of Inspection Personnel and (3)Compliance of Measuring Devices & Equipment. In last two years [2016-2018] by ensuring Acceptance Benchmark only, more than 70% reduction in premature failure [Crack in Thread Connection; where 50% of those are potential NPT cases] in drilling Tools achieved. Our App provide the user to analyze Inspection data. The trend analysis of tools helps in its planning and utilization plus the data can be directly input to modify Service Quality Plan to optimizing the asset utilization & serviceability. The above are some of the immediate befit to Oil Company and Drilling Contractor by AIMS. This paper also discusses one more dimension of it, Reliability in Service Quality. As this AIMS Tool is synchronized with our, (1)EAM software that manages company's all assets and resources, and (2)OMS controlling the process, the integration of all three increase the overall efficiency of the service and results in profitability of a business.

This paper presents a methodology for identifying blunt flaws in piping using in-service data from ultrasonic inspection tools. The method is applicable to data obtained from predetermined inspection grids, or directly from bracelet or array type inspection tools. The flaw edge and size are identified by calculating the three-dimensional slope vector (i.e., magnitude and direction) of each point in the kriging interpolated wall thickness profile. The transition from a steeper slope to a relatively flat profile is then used by a search algorithm to determine the flaw edge. The method is applied to the flaw assessment of feeder piping in CANDU nuclear reactors. The results show that in addition to identifying blunt flaws, the developed methodology also provides a convenient way for characterizing the flaw dimensions for structural integrity assessment. The uncertainty in the results is mainly attributed to the signal loss and coverage error associated with the inspection data.

In-service inspection of gas and oil pipelines is a subject of great current interest.� Issues of safety and fitness for service have driven extensive efforts to develop effective monitoring and inspection techniques.� A number of effective NDT techniques have been developed for screening to identify regions of interest for more detailed evaluation.� The three anomalies of greatest interest are (1) corrosion, (2) mechanical damage and (3) stress corrosion cracking (SCC).� In this paper we will focus on the application of laser ultrasonics to the characterization of SCC. Stress corrosion cracking is the phenomenon in metals wherein the simultaneous presence of tensile stress, a corrosive environment and a susceptible metallurgy leads to the nucleation and propagation of highly irregular and complex cracks, usually found in closely spaced clusters or colonies. In pipelines, SCC has been a particularly elusive and challenging problem. � Several pipeline failures around the world have been attributed to SCC since its discovery in pipelines in the 1960s.� While the number of incidents attributed to SCC is less than those attributed to other threats to pipelines such as corrosion or mechanical damage, it constitutes a formidable challenge due to the following key reasons: ��� �No reliable and accurate inspection tools or predictive modeling based tools exist that are capable of determining what locations along the pipeline are affected by SCC. ��� �No reliable and widely accepted assessment tools exist for evaluation of SCC, once found. ��� �No reliable and widely accepted tools exist that are capable of measuring the depth of these cracks accurately. ��� �No generally accepted method for fitness for service evaluation of SCC exists.

The group of scientists that make up the Intergovernmental Panel on Climate Change found in 2007 that the warming of Earth’s climate is unequivocal and largely due to human activity. Earth’s climate has changed in the past, though the recent magnitude and pace of changes are unprecedented in human existence. Recent decades have been warmer than at any time in roughly 120,000 years. Most of this warming can be attributed to anthropogenic activity, primarily burning fossil fuels (coal, oil and natural gas) for energy. Burning fossil fuels releases carbon dioxide and other heat trapping gases, also known as greenhouse gases, into the atmosphere. This warming cannot be explained by natural causes (volcanic and solar) alone. It can be said with confidence that human activities are primarily responsible for the observed 1.5 ˚F increase in 20th century temperatures in the Pacific Northwest. A warmer climate will affect this state substantially. In 2007, the Oregon State Legislature charged the Oregon Climate Change Research Institute, via HB 3543, with assessing the state of climate change science including biological, physical and social science as it relates to Oregon and the likely effects of climate change on the state. This inaugural assessment report is meant to act as a compendium of the relevant research on climate change and its impacts on the state of Oregon. This report draws on a large body of work on climate change impacts in the western US from the Climate Impacts Group at the University of Washington and the California Climate Action Team. In this report, we also identify knowledge gaps, where we acknowledge the need for more research in certain areas. We hope this report will serve as a useful resource for decision-makers, stakeholders, researchers and all Oregonians. The following chapters address key sectors that fall within the biological, physical and social sciences in the state of Oregon.

External coatings are routinely used to protect transmission pipelines from corrosion; however, coatings may degrade or disbond over time enabling corrosion to occur. Transmission pipeline operators often use magnetic flux leakage (MFL) in-line inspection tools to detect metal loss corrosion defects. Rather than finding the cause of a problem, failure of the coating within a corrosive environment, MFL corrosion surveys only find the result of the problem, corrosion defects that may permanently alter the pressure carrying capacity of the pipeline. Stress corrosion cracking (SCC) can be detected using in-line inspection (ILI) technology, but the availability of tools is limited and the cost of inspection is high compared to MFL inspection. SCC almost always occurs at coating faults; direct coating assessment could indicate future problems that could degrade the serviceability of the pipeline. In this project, a new sensor was developed to assess external coating that could work with currently available ILI tools for minimal additional cost to perform the inspection. The sensors, electromagnetic acoustic transducers (EMATs), generate ultrasonic waves that are guided by the pipe material around the circumference of the pipe. The coating material and adherence can influence the propagation of the ultrasonic waves; changes in ultrasonic signal features were attributed to coating faults. This development used modeling and experiments to establish a more optimal configuration for coating assessment. A multiple feature approach was used. A commonly used feature, signal amplitude, provided good sensitivity to coating condition but was influenced by inspection variables. One unique feature identified in this development is arrival time of the ultrasonic wave. For the wave type and frequency selected, the wave velocity was different for bare and coated pipe. Therefore, disbonded or missing coating can be detected by monitoring arrival time of the ultrasonic wave, a feature that is amplitude independent. Another feature for assessing coating, absorption of selective frequencies, was also demonstrated. Coating assessment capability was experimentally demonstrated using a prototype EMAT ILI tool. All three detection features were shown to perform well in an ILI environment as demonstrated at Battelle"s Pipeline Simulation Facility and BJ Inspection Services pull rigs. Improvement to the prototype occurred between each test; the most significant improvement was the design and construction of a novel set of thick-trace transmitting and receiving Printed Circuit Board (PCB) EMAT coils. Implementation variables such as moisture and soil loading were shown to have a minimal influence on results.
