WeBid: A web-based framework to support early supplier involvement in new product development

It has been found from the contemporary research in the fields of concurrent engineering and supply chain management that significant benefits can be achieved if suppliers are involved in the early stages of product development process. However, recent investigation in manufacturing industries has also revealed that this approach is not widely practised in industries and its implementation has been a great challenge to researchers and practitioners. The research reported here proposes to develop an overall methodology for enabling better supplier involvement in new product development process and to demonstrate the framework through a prototype web-based platform on the Internet/intranets using the web technology. This paper presents some results from the initial investigation, development and implementation of the proof-of-the-concept prototype system called WeBid.     

A new distance measure based on the weighted induced method and its application to Pythagorean fuzzy multiple attribute group decision making

This paper investigates a novel induced ordered weighted averaging (IOWA) distance operator and its application in Pythagorean fuzzy (PF) multiattribute group decision making (MAGDM). First, a new induced aggregated distance operator named the weighted IOWA distance (WIOWAD) operator is developed, which differs from the existing methods in that it considers the dual roles of the order-inducing variables at the same time. In other words, in addition to inducing the order of the arguments, the order-inducing variables of the WIOWAD operator also plays an important role in moderating the associated weight vector. Some useful properties and different families of the WIOWAD are also discussed. Then, an extension of the WIOWAD within the PF situation is presented, thus obtaining the PFWIOWAD operator. Furthermore, a MAGDM method based on the PFWIOWAD is introduced. Finally, the practicality and effectiveness of proposed approach are illustrated in a research and development project selection problem.     

Towards the development of a framework to create a virtual organisation breeding environment in the mould and die sector

The effective creation of Virtual Enterprises emerges after the development of: (i) a new working culture and (ii) a computer-enabled infrastructure supporting inter-operation of companies. These developments are facilitated if the potential partners belong to a Virtual Organisation Breeding Environment (VBE). This paper describes a framework to create and support the life cycle of Virtual Enterprises operating (relying on a VBE) in the mould and die sector. The proposed framework is called AmbianCE and it is the result of a 5-year research project in the field of Collaborative Network Organisations. The AmbianCE framework has been validated in a Brazilian VBE called Virfebras. A peculiar characteristic of Virfebras is that many of its members are competitors.     

Tracing the development of teacher knowledge in a design seminar: Integrating content,pedagogy and technology

Effective technology integration for teaching subject matter requires knowledge not just of content, technology and pedagogy, but also of their relationship to each other. Building on Schulman’s [Schulman, L. S. (1987). Knowledge and teaching: foundations for a new reform. Harvard Educational Review, 57(1), 1–22] concept of pedagogical content knowledge, we introduce a framework for conceptualizing Technological Pedagogical Content Knowledge—TPCK [Mishra, P., Koehler, M.J., (in press). Technological pedagogical content knowledge: A new framework for teacher knowledge. Teachers College Record]. We report the results of a semester-long investigation of the development of TPCK during a faculty development design seminar, whereby faculty members worked together with masters students to develop online courses. Quantitative discourse analysis of 15 weeks of field notes for two of the design teams show participants moved from considering technology, pedagogy and content as being independent constructs towards a richer conception that emphasized connections among the three knowledge bases. Our analyses suggests that developing TPCK is a multigenerational process, involving the development of deeper understandings of the complex web of relationships between content, pedagogy and technology and the contexts in which they function. Pedagogic, pragmatic, theoretical, and methodological contributions are discussed.     

The new digital divide: the confluence of broadband penetration,sustainable development,technology adoption and community participation

There have been significant efforts during the last years to define indicators to estimate the digital divide among nations, regions and social groups. The first attempts considered are mainly parameters of technical nature related with access to computers and Internet connectivity. Though these technical parameters gave an initial indication of the magnitude of the digital divide, they did not provide a complete picture of its dimension and context. In this paper, we propose that grass roots participation and integrating socioeconomic development with human values and taking advantage of the advent of emerging mobile wireless and efficient broadband technologies play a significant role in redefining the nature of the digital divide. The understanding of the new paradigm of broadband penetration, sustainable development, technology adoption and community participation is fundamental to develop national plans and agendas for digital inclusion, particularly in rural and underserved populations contexts.     

Towards the refinement of forum and asynchronous online discussion in educational contexts worldwide: Trends and investigative approaches within a dominant research paradigm

The growth of asynchronous online discussion (AOD) in primary, secondary, undergraduate, and post-graduate contexts and courses has resulted in a growing body of literature that provides valuable insights into the issues surrounding the use of online writing, online discussion, and distance and blended learning in formal education worldwide. This phenomenological critical literature review provides an overview of research focused on forum use and AOD published from 2008 to 2012. Papers were chosen based on a selection process suggested by Wu et al. (2012), where nine of the most influential e-learning education and educational review journals were searched according to year, 2008–2012, and the following keywords: forum, threaded discussion, and threaded chat. Three teachers/educational researchers, each with at least five years of experience using forum and AOD in university contexts, further filtered the corpus through following a detailed inclusion/exclusion procedure, which resulted in a refined corpus of 43 journal papers. Quantitative analyses of results reveal most AOD research in educational contexts from 2008 to 2012 was carried out through or on Learning Management Systems (LMS) platforms in university settings, within computer and education classes, with blended learning dominating distance learning contexts. Most research settings were based in Asia and Europe, while the three countries with the most AOD publications were Singapore, Taiwan, and the U.S. In addition, the journals dominating the field were Computers & Education, followed by Journal of Computer Assisted Learning, and Australasian Journal of Educational Technology. The refined corpus was also analysed qualitatively via phenomenological method (Smith, Flowers, & Larkin, 2009), in order to identify and contextualize meaningful statements and themes. Discussion focuses on the existence of a dominant research paradigm that we divide into four investigative impulses and discuss: argumentative, comparative, relational, and analytical. Specific representative examples of each investigative impulse are thoroughly discussed and critiqued, and as a result, should be of significant value to all stakeholders, including researchers, instructors, and students, involved in forum and AOD use in educational contexts globally.     

From Dewey to Gates: A model to integrate psychoeducational principles in the selection and use of instructional technology

The purpose of this article is to propose a model to integrate educational mastery principles that emphasize cooperative and learner-centered instruction in higher education with the new advances of instructional technology, and to present a pilot case study to exemplify the model. It is clear that in spite of tremendous efforts by colleges and universities to introduce instructional technology in the classroom, many faculty remain skeptical of the new technologies. It is suggested that in order for instructional technology to be widely accepted and used by faculty, the value of this technology to improve classroom instruction has to be proven. It is proposed that this can be achieved by applying learner-centered principles, in which the instructional objectives of the class are directly linked both to the needs of the student and the role of the instructor in the classroom, which in turn determine the appropriate type and use of instructional technology. It presents a pilot case study in which a technology was used to teach a basic psychology concept.     

A collaboration model for new product development through the integration of PLM and SCM in the electronics industry

As customer requirements for high-tech products vary and become complicated, the lifecycle of these products becomes much shorter. In response to this market environment, many manufacturing companies have established a global simultaneous launch strategy for new products to occupy markets before competitors. In this process, careful scheduling of the global simultaneous launch strategy is critical. In particular, to meet the launch schedule for each country in which a new product will be released, a collaboration process among relevant departments must be prepared, and correct product information should be maintained among major cooperative work support systems according to new product development business processes. This paper suggests a collaboration model integrating product lifecycle management and supply chain management as an approach to supporting complicated new product development procedures. We use a practical case study to evaluate this model.     

Problems in the interplay of development and IT operations in system development projects: A Delphi study of Norwegian IT experts

Context

The assumption of the presented work is that the ability of system developers and IT operations personnel to cooperate effectively in system development projects has great impact on the quality of the final system solution, as well as on the service level of its subsequent operation.

Objective

The present research explores the interplay of system development and IT operations and the challenges they are meeting. We are especially interested in identifying problems encountered between these two parties in system development projects.

Method

We identify and rank problems by using a ranking-type Delphi study. We involved 42 Norwegian IT experts and split them into three expert panels: system developers, IT operations personnel and system owners. We then guided them through the three phases of the Delphi method - brainstorming, reduction and ranking.

Results

A comprehensive list of 66 problems, organized into seven groups, is compiled. Through a selection and ranking procedure, the panels found the following to be the six most serious problems in the interplay of system development and IT operations: (1) IT operations not being involved in the requirements specification; (2) poor communication and information flow; (3) unsatisfactory test environments; (4) lack of knowledge transfer; (5) systems being put into production before they are complete; and (6) operational routines not being established prior to deployment.

Conclusion

The sheer amount and variety of problems mentioned and the respondents’ explanations confirm that this interplay needs attention; the parties agree that they do not cooperate effectively in development projects. The results imply that IT operations should be regarded as an important stakeholder throughout several systems development activities, especially requirements analysis, testing and deployment. Moreover, such involvement should be facilitated by an increased focus on enhancing cooperation and communication.     

The development of a cognitive tool for teaching and learning fractions in the mathematics classroom: A design-based study

Two cycles of design-based research of a cognitive tool (CT) for teaching fractions have been completed. Following the success of a quasi-experimental study of the enhanced CT derived from the second cycle of design-based research, this article reports the findings of a pre-test–post-test control group empirical study using the enhanced CT in the classroom. The results indicate that there were no statistically significant differences in learning outcomes between the exploratory learning approach, using the CT, and the traditional direct teaching approach. The CT enabled students to generate a procedural knowledge of adding and subtracting fractions with like and unlike denominators through an exploratory learning process. Teachers asserted that the CT was effective for stimulating reciprocal tutoring among students, and students were enthusiastic about using the CT as an educational tool. Hence, the CT has potential for further development as a tool for promoting collaborative learning in the classroom.     

Learning with new information technologies in schools: perspectives from the psychology of learning and instruction

Abstract  The starting point of the present paper is that the New Information Technologies can only contribute substantially to the improvement of schooling, if they are appropriately embedded in powerful learning environments. The realization of this embedding requires that inquiry and development relating to educational computing are more explicitly based on recent research on learning and instruction, because this domain of investigation has produced an empirically underpinned knowledge base that can guide and orient the design of rich and powerful computer-supported learning environments. In that perspective a series of important and relevant findings of research on learning and instruction are reviewed; they relate to the three major components of a theory of learning from instruction, namely a theory of expertise describing skilled performance in a domain, a theory of the acquisition processes required to achieve competence, and a theory of intervention strategies that are appropriate for eliciting those acquisition processes.     

Reliability of antibodies to Candida methionine synthase for diagnosis, prognosis and risk stratification in systemic candidiasis: A generic strategy for the prototype development phase of proteomic markers

To be able to diagnose systemic candidiasis (SC) and to predict outcomes in SC patients are still challenging tasks for physicians. Previous proteomic studies suggest that anti-Candida methionine synthase (Met6p) IgG antibodies may be a candidate marker for SC. To evaluate their reliability for diagnosis, prognosis and risk stratification in SC, we developed a generic prototype strategy for their measurement in SC. Receiver-operating-characteristic curve analyses revealed a high diagnostic accuracy for this prototype format, which was slightly better to that for the widely used Western blot assays. Multivariate logistic-regression models showed a positive association between serum anti-Met6p IgG antibody levels and SC risk that was independent from established SC risk factors and other baseline variables. After adjusting for and stratifying according to known prognostic factors, a significant trend toward a lower two-month mortality risk with increasing levels was evidenced in SC patients at presentation. We conclude that these antibodies may be useful in discriminating SC from non-SC patients and determining risk stratification in SC. These may also confer protection against SC and be valuable for the design of future immunotherapies. Furthermore, our prototype format has the potential to make impact on other infectious diseases, cancers, allergies or autoimmune disorders.
