Formal Definitions

Currently, the democratization of wireless communication means coupled with the advanced technological hardware can offer portable devices that fit in the hand with a very large capacity of computation such as PDAs, mobile phones and even wireless sensors. The users' preferences, in which the document is presented, may need to be considered because the adaption of multimedia content through them is an important aspect of Quality of Service. Our research work focuses on the adaptation of multimedia documents with a strong interest on the interaction based on the user preferences. In this paper, we propose formal definitions of concepts related to the technical adaptation that selects a relevant policy in order to perform an adapted document in the situation where conflicts are detected between the heterogeneity of multimedia document properties and the user needs. We present also an architecture for adapting multimedia contents based on the preferences and we develop a user preference interface. We illustrate the proposed approach with a case study.

This study aimed to develop a case-based design framework to analyze online us-er reviews and understanding the user preferences in a Massive Open Online Course (MOOC) content-related design. Another purpose was to identify the fu-ture trends of MOOC content-related design. Thus, it was an effort to achieve da-ta-driven design automation. This research extracts pairs of keywords which are later called Feature-Sentiment-Pairs (FSPs) using text mining to identify user preferences. Then the user preferences were used as features of an MOOC content-related design. An MOOC case study is used to implement the proposed framework. The online reviews are collected from www.coursera.org as the MOOC case study. The framework aims to use these large scale online review data as qualitative data and converts them into quantitative meaningful infor-mation, especially on content-related design so that the MOOC designer can de-cide better content based on the data. The framework combines the online re-views, text mining, and data analytics to reveal new information about users’ preference of MOOC content-related design. This study has applied text mining and specifically utilizes FSPs to identify user preferences in the MOOC content-related design. This framework can avoid the unwanted features on the MOOC content-related design and also speed up the identification of user preference.

There are several ways to make computing accessible to everyone, such as providing teaching material in text and videos formats. In particular, the recording lectures and talks with the aim of making the corresponding content available (as a video or multimedia document), is a common activity in many locations world-wide. Two common approaches used to recording such events are using a studio or instrumenting a conventional classroom with cameras and microphones so as to record the activity in-place. In this paper we study the influence that the use of these two environments may have in the recording process. We report on a case study with 27 participants which recorded short academic talks in the two scenarios and also discuss how the environment affected their behavior. Understanding such influences may inform the design of infrastructures aimed at supporting the authoring of interactive multimedia documents from live experiences.

Purpose – This paper aims to demonstrate work undertaken by Muhimbili University of Health and Allied Sciences (MUHAS) Library in an effort to integrate Web 2.0 technologies in its functions to enhance the quality of its services in Tanzania. Design/methodology/approach – The study conducted an exploratory questionnaire survey to assess user requirements among undergraduate medical students at MUHAS, developed Library 2.0 services, conducted training and created awareness. Findings – The paper shows that Web 2.0 technologies can be implemented effectively according to university goals, user's needs, deployment of user friendly tools, and capacity building among librarians and users. Students positively supported the adoption of Library 2.0 services at MUHAS. Library 2.0 services improved the quality of MUHAS library services, despite various challenges related to infrastructure, awareness, literacy, inadequate staff, security and ownership of Web 2.0 services. Research limitations/implications – The study findings may not be widely replicated because this article is based on a case study of the integration of Web 2.0 technologies into the library functions of MUHAS. This study did not examine the use of Library 2.0 applications among library users (such as faculty and students) which could illuminate further the case study. Practical implications – Most academic libraries in Africa have not yet adopted Web 2.0 technologies to improve their services. The user preferences, technology adoption, and challenges faced from the present study can help other libraries to plan and integrate their Library 2.0 technologies in their services. Originality/value – MUHAS Library offers a practical example of how Web 2.0 services can be adopted to enhance the quality of academic library services in an African context. This paper is of significance to academic libraries that are still considering their options with regard to the application of Web 2.0 technologies.

Purpose – The purpose of this paper is to highlight the environmental behaviour of the Algerian firms, on the one hand, and, on the other hand, showing how the involvement of stakeholders may change this behaviour. Design/methodology/approach – In order to set the environmental quality management (EQM), the paper has first been inspired by a mobilisation grid which has allowed the authors to evaluate the degree of dialogue between the stakeholders and the SONATRACH Group which constitutes the case study. Then, the various interviews held at the six sites of this group have allowed to determine the percentage rate of the stakeholders’ mobilisation. Findings – The suggested approach highlights two field studies. First, the aim was to check the mobilisation of the stakeholders of the SONATRACH Group. Then, in order to confirm the importance of mobilising the stakeholders for a better environmental integration, the authors had to evaluate the EQM by measuring the response rate of these stakeholders in percentages. Research limitations/implications – The contribution makes it possible to emphasise the contribution of stakeholder theory in environmental construction based on the mobilisation of stakeholders. Practical implications – In Algeria, some production sites are ranked as polluting. For this research work, the paper has chosen the sites of the SONATRACH multinational. Being conscious of the importance of integrating the environmental dimension, the group has carried out real changes by involving all stakeholders. Originality/value – The objective of this paper is to show the importance of mobilising the stakeholders who play a role in resolving economic and/or environmental issues to help the Algerian firms improve their environmental situation.

Significant Difference

Purpose: In an era of heightened competition to sustain patient loyalty, quality of interpersonal experiences with the staff, operational quality of hospital operations and overall satisfaction and quality of the healthcare services, in general are to be understood in-depth in both public as well as private organisations. The concept of service quality has led to the growing research on various concepts such as total quality management, market orientation, learning orientation, strategic orientation along with invigorating focus on the customer loyalty and relationship management. The outcomes of service quality (customer relationship management and loyalty), end means for the organisational success, are most significant performance measurement tools in the present competitive market. The present study is an effort in this regard to identify the factors in sustaining customer longevity. Till today few studies in the developing settings were conducted to understand the types of relationship that exists between patient-loyalty and service quality. This study analyses the suitability of customer loyalty concept in the government hospitals through using a case study of one of the biggest hospitals operating in India. Methodology and Tools Applied: The research work is the case study of Civil Hospital Ahmedabad. The data is collected from 205 indoor patients of four departments namely general medicine, orthopedic, pediatrics, obstetric and gynecology. Inter and intra relationship among the measures of service quality and patient loyalty were analysed by using relevant statistical tools to draw out inferences. Findings: Among the three patient loyalty components, using provider again for the same services is found to be more significant followed by using provider again for different services and recommending providers to others in relation to overall service quality as dependent variable, and beta values are figured out as 0.15, 0.12 and 0.09 respectively The 35% R Square value for the model service quality – patient loyalty model indicate weak predictive power of this model. However at the same juncture the study found that no significant difference in the patients' perceptions with respect to patient loyalty and quality and per se, may be concluded that both are identical measures. Alternatively the more satisfied the patients are with the quality of their interactions with staff, the more likely they are going to take treatments for similar and different medical problems and would recommend the provider to their relatives and friends.

 Macroinvertebrates are widely considered as indicators of water quality. The present research work was conducted in Bhalu khola, a tributary of Budhigandaki River, Nepal, to identify water quality using macro invertebrates with Nepalese Biotic Score (NEPBIOS), and examine its applicability by comparing with Water Quality Index (WQI).The diversity of macro invertebrates in the studied river was high as depicted by Shannon Wiener Diversity Index. Altogether, 103 macro invertebrates were identified from 11 families and five orders. There were no dominant species, and most of the species were in clumped distribution. According to NEPBIOS index, river water was found to comply with the characteristics of WQ class I-II that means water quality of the river was good. Other indices such as Hilsenhoff and Lincoln quality index (LQI) index also supported this result. Similarly, water quality index (WQI) also showed similarity with NEPBIOS index, indicating water appropriate for drinking purpose. Thus, it is concluded that the macro invertebrates can be used as economic tools for determining water quality of streams and rivers as efficient water quality indicators.International Journal of Environment Volume-4, Issue-3, June-August 2015Page: 55-68

The Given

Film reject analysis is a planned and systematic action necessary to provide adequate confidence that a product or service will satisfy the given requirement for quality of image or radiographs. In this research work, reject film analysis as quality assurance element will be carried out in 3 selected hospitals in Plateau state, Nigeria for different rejected film sizes in each case respectively from December, 2018- December, 2019. Rejected radiographs were collected analyzed and categorized based on body parts such as chest, skull, knee, lumbar sacral, shoulder, neck, femur and pelvis. The reasons for rejection were categorized as: Over exposure, Under exposure, Poor processing, Poor positioning, Wrong placing of anatomical marker, Fog, Artifact and Multiple exposure. The three studied hospitals (selected by convenience), H1, H2, and H3 are located in Jos and environs. From this study, it was observed that the anatomical part mostly rejected was the chest and the highest reason for the rejected radiographs was Under exposure. The reject rates of Hospitals H1, H2, and H3 were found to be 8.85%, 6.65% and 5.6% respectively which were above the World Health Organization(WHO) but within the Conference of Radiation Control Program Directorate (CRCPD) recommended permissible values of 5% and (5-10%) respectively. The findings imply that patients may have been exposed to avoidable radiation doses

The Relationship

Open space such as market square is a communal ground where people carry out their various functional activities. This research work is undertaken in order to fill the knowledge gap in areas of people and place relationship, where improvements are needed to overcome challenges in the provision of facilities, design, and planning. In view of its significance, it becomes imperative to explore the relationship between the utilization of market square and residents’ attachment to the community. Therefore, 382 respondents’ views on market dependence, identity, activities preferences, and attachment to the community were collected through self-administered questionnaires. The findings from Structural Equation Modelling (SEM) using AMOS tool version 22 for the tested hypothesized model reveal that residents’ dependence and identity with market square had positive significant impacts on residents’ attachment to the community with standardised path coefficient values of 0.32 and 0.48 respectively. It is therefore suggested that appropriate machinery should be put in place towards improving the quality of the market square to further enhance users’ interaction cum the sustainability of the community in Nigeria.
