Abstract Ubiquitous computing shifted the way how users interact with applications. The demand of information anytime and anywhere impacts the daily life of its users, be it work related or personal. Difficulty arises when determining the quality of ubiquitous application due to lack in appropriate metrics of quality models, which serves as the motivation behind this paper. The aim of this paper is to assess the quality of ubiquitous application using comparative analysis of quality model metrics via meta-metrics approach. Preliminary review mapping was conducted where distinctive quality characteristics of ubiquitous applications from AQUARIUM model are identified. Metrics mapping was then conducted to compare metrics characteristics with quality characteristics via value assignment using meta-metrics technique. Results shows that most of the metrics mapped are not of definitive derivation, providing opportunity to have a more structured and defined measurement function.

Software Quality Models

Software quality models link internal attributes of programs with external quality characteristics. They help in understanding relationships among internal attributes and between internal attributes and quality characteristics. Object-oriented software quality models usually use metrics on classes (such as number of methods) or on relationships between classes (for example coupling) to measure internal attributes of programs. However, the quality of object-oriented programs does not depend on classes solely: it depends on the organisation of classes also. We propose an approach to build quality models using patterns to consider program architectures. We justify the use of patterns to build quality models, describe the advantages and limitations of such an approach, and introduce a first case study in building and in applying a quality model using design patterns on the JHotDraw, JUnit, and Lexi programs. We conclude on the advantages of using patterns to build software quality models and on the difficulty of doing so.

ABSTRACT The post-harvest quality of pineapple guava fruit is determined by the storage and prevailing weather conditions during growth and development. This study proposes a model for post-harvest fruit quality according to the storage and weather conditions in the pineapple guava growing region. Physiologically ripe fruit were collected during two harvests from two locations within the Department of Cundinamarca (Colombia): Tenjo and San Francisco de Sales. The fruits were stored at 18 ± 1 °C (76 ± 5% relative humidity (RH), over 11 days) and at 5 ± 1 °C (87 ± 5% RH, over 31 days), and the quality attributes were evaluated every two days. Models of the most significant physio-chemical quality characteristics of the post-harvest fruit were developed by using the Excel® Solver tool for all data obtained in the two crop periods. The results showed that storage and prevailing weather conditions, which differed according to the altitude of the growing site, had considerable impacts on the physio-chemical characteristics of the fruit throughout the post-harvest ripening process.

Potential Benefits

Quality is one of the factors that ensure the commercial success and safety of using the software. Quality is understood as conformity the explicit and implicit requirements of various stakeholders. It is necessary to ensure a joint understanding between developers and users, engineers need to understand the meaning of the concept of quality, characteristics and importance of quality for the developed or maintained software. Measurements are the basis for quality assurance. They are the main tool for managing the life cycle of software products, assessing the implementation of plans and monitoring. To quantify quality, it is necessary to measure the characteristics of the software. Standardization provides unification of requirements for quality, its measurement and assessment. The use of standards has many potential benefits for any organization, especially in key areas such as measuring the quality of software products, information and measurement systems. Recognized international standards organizations have published the ISO/IEC 25000 series of standards for systems and software quality requirements and evaluation (SQuaRE), which is gaining widespread practical application. The paper discusses a series of the SQuaRE international standards, analyzes the relationship between the quality model, quality characteristics, quality measures and a new concept, i.e., a quality measure element of the software, presents the measurement of quality based on these standards.

Time To Delivery

Open Source Software (OSS) is an emerging technology of software development in present era, careful implementation and procurement can gives us more benefits for OSS- adapting organizations. But any failure in design, development and procurement will leads to major impact to OSSdeveloper organization (community) to stop their further release and completely destroy the adapted system. Success of any software’s based on it’s time to delivery, development cost and effectiveness. Open source software can fulfill these factors due to its availability of source code, openness and sustainability of Technical quality among development community. At the same time, more number of developers in a community of any OSS leads to delay in development. But it has chance to improve software effectiveness in terms of defect free, since software can be reviewed using various testing methodology, tools and plans in different perception. An OSS has more issues such as lack of architecture design, co-ordination, organizational structure and documentation, removing these issues will strengthen the quality of OSS. This paper includes the quality model and framework for organized communication the quality characteristics in an appropriate aspects is required since unorganized communications wherever people involved can leads to high quality risk.

The Relationship

The chapter presents an extended version of a quality-driven, MDA-based approach for database system development. The extension considers the relationship between successive models in the MDA approach. In particular, it gives rise to the introduction of domain ontology as a model preceding the CIM model as well as allows assessment of the extent to which the successive model is conformant with the preceding model. The chapter consists of four parts. The first part gives a short presentation of quality models and basic MDA concepts. The second one discusses the specific relationships between software development and quality assessment processes. The third part presents the Q-MDA framework and the proposal of a new quality characteristic (model conformance) with some measures for assessing the quality of a specific model in the context of other models. The last part contains an example of the framework application limited to the proposed quality model extension.

The article clarifies the existing approaches of comparative analysis and assessment of the level of development of different societies taking into account their civilizational characteristics. This specification allows solving the fundamental contradiction of theories of development of modern society and modernization which is due to the uncertainty over the common and different for various forms of modernity. Based on a critical review of three approaches (institutional & universalistic, local & civilizational, formal & comparative) the key dimensions of development of societies in the global world system are identified: economic performance and financial security, efficiency of institutions, values and motivation, human capital and cognitive mobilization, quality of life by objective and subjective criteria, health and life expectancy, social inclusion, cohesion and empowerment. The Capability Approach and related social quality model are used to improve the existing tools for adequate comparison of societies with different civilizations origin and programs of modernization.

Purpose The purpose of this paper is to provide a multidimensional model for assessing the quality of corporate environmental reporting (CER) incorporating both preparer- and user-based views. Design/methodology/approach As opposed to frequently used researcher-chosen proxies, the authors used an online questionnaire asking preparers and users how they assess the quality of a company’s environmental report. Findings The analysis of the responses of 177 users and 86 preparers shows that quantity was not perceived as the most significant element in determining quality. Besides quantity, the respondents also perceived information types, measures used, themes disclosed, adopting reporting guidelines, inclusion of assurance statement and the use of visual tools as significant dimensions/features of reporting quality. Research limitations/implications The online questionnaire has some limitations, especially in terms of researcher being absent to clarify meanings and, hence, possibilities that respondents may misinterpret the questionnaire elements. Practical implications Considering that robust, reliable measurement of reporting quality is difficult, preparers, standard setters and policy makers need multidimensional quality models that incorporate both users’ perceptions of quality and preparers’ pragmatic understanding of the quality delivery process. These will make the preparers informed of whether their disclosure may be falling short of users’ expectations. Originality/value Amid, increasing complexity of CER, the research contributes to the growing body of literature on assessing the quality of CER by developing a less subjective, multidimensional, preparer–user-based quality model. This innovative quality model goes beyond the traditional quality models, subjective author-based quality measures. Focussing on the three dimensions of reporting quality – content, credibility and communication – it also offers a high-level resolution of meaning of CER quality.

The objectives of this article are (1) to explore the perceived factors of service quality affecting the decision to use services in private hospitals, (2) to analyze the relationship of service quality models and the decision to use services in private hospitals, and (3) to develop service quality models that influence the decision to use services in private hospitals. The sample group was 400 patients who were admitted to private hospitals listed on the Stock Exchange of Thailand, by the convenience sampling method. The statistics used in this research were descriptive statistics, percentage, mean, and standard deviation. The correlation between factors was used to analyze one-way ANOVA and construct a multiple-linear regression equation by the stepwise method. The results of the research were found that 1) factors affecting the decision to use services in private hospitals consisted of 8 factors, namely service quality of doctors, service quality of nurses, service quality for diagnosis, service quality of reception, service quality to stay in private hospitals, service quality of patient foods, service quality of cleaning in patient rooms, and service quality of payments. 2) The regression equation of the service decision can have six independent variables into the regression equation. They were able to jointly explain 65.8% variation in service decision and the resulting regression equation has a variance of 0.378. 3) The results of the development of the service quality model by the multiple linear regression method using the stepwise method, the key factors were consistent with the empirical data. It has a good predictive ability with quadratic multiple correlations (R2) of 0.658 or 65.8%, which can be written as a regression equation to be a key factor in the development of the service quality model that influence the decision to use services in private hospitals.
