Abstract

The effects of oxygen on solder surface tension, wetting time and surface damping are presented. Oxygen levels greater than 10 ppm lower surface tension, increase wetting time and increase surface damping. Decreased surface tension leads to higher misalignment defects in reflow soldering, but can lower the incidence of dewetting. Increased wetting times can increase nonwetting defects in both wave and reflow soldering, especially when using noclean fluxes. Increased surface damping can lead to lower bridging rates in wave soldering, provided that the oxygen level and flux levels are properly balanced. Choosing the optimum oxygen level for production soldering is tradeoff between the stability and the versatility of the process. The most stable soldering processes will be those performed in an inert atmosphere with less than 10 ppm oxygen .These processes are insensitive to variations in soldering machine operating parameters (i,e. a larger process window).This is most desirable for manufacturers soldering large volumes of a given circuit board. The soldering process can be optimised by optimising the circuit board design. The most versatile soldering processes will be those performed in an inert atmosphere with controlled addition of oxygen in the range of 100 ppm to 10,000 ppm (1%). This will be most desirable to manufacturers soldering short runs of a large variety of circuit boards. The soldering process is best optimised by controlling the soldering machine operating parameters (oxygen, flux, preheat, conveyor speed, etc.).

Abstract

Purpose

This paper aims to provide insights into the evolution of the concept of interdisciplinarity in management science and management education.

Design/methodology/approach

A range of recently published (19932002) works, which aim to provide practical advice rather than theoretical books on pedagogy or educational administration, are critiqued to aid the individual make the transition into academia. The sources are sorted into sections: finding an academic job, general advice, teaching, research and publishing, tenure and organizations.

Findings

The paper finds that in the evolution of management education and management science interdisciplinarity took different forms: synoptic and instrumental. Both forms resulted from different knowledge strategies of competing and cooperating disciplines. It concludes that in The Netherlands instrumental versions of interdisciplinarity in management research and education prevailed.

Research limitations/implications

The paper studies the evolution of interdisciplinarity in management education and management science in the Dutch higher education context. It assumes that the pattern of evolution differs from country to country.

Practical implications

Interdisciplinarity is a complex concept. This study provides practical insights into the dynamics of interdisciplinary collaboration.

Originality/value

Much has been written about interdisciplinarity in science and education. However there is hardly any empirical and historical research on this topic.

Abstract

Purpose

Integration is a key element of supply chain management (SCM) and a lot of research has been executed within the field of supply chain integration (SCI). The purpose of this paper is to particularly identify the intellectual research front and foundation of SCI and how they developed over time.

Design/methodology/approach

The authors examined more than 1,700 peer-reviewed academic papers that were published between 1995 and 2019 in nearly 40 relevant peer-reviewed academic journals (all indexed in Web of Science). The authors analysed the structure of more than 55,000 individual references with the R-package bibliometrix and used VOSviewer for visualization.

Findings

The SCI research front is characterized by papers that show the effects of SCI on the firm performance, the consequences of SCI on SCM in general and present the enablers of SCI. The research front is embedded within the resource-based, transaction cost and contingency theory. The intellectual foundation refers to conceptual modelling, definitional clarification and integration dimensions. The research identifies Frohlich and Westbrooks (2001) paper as the central reference for this research area. The dynamic evolution of the intellectual foundation of SCI changed from theorising in Phase 1 (19952006) towards empirical testing in Phase 2 (20072019).

Research limitations/implications

The results refer to the SCI discussion within a preselected number of peer-reviewed academic journals and to the data quality as provided by the Web of Science.

Originality/value

The study explored the research front and intellectual foundation of SCI. It reveals the most important papers and journals of this area by using bibliometric tools such as bibliometrix, biblioshiny and VOSviewer. The paper shows trends in research themes, theories and methodological developments.

Abstract

Purpose

Technologies for teaching abound, but many of them are proprietary systems and software that require institutional and individual subscriptions for use. Instructors and librarians in higher education have open source and free options for many types of teaching technologies. While some of these technologies are free to users, open source goes beyond that and makes the source code that runs it available as well. These provide more options to enhance teaching.

Design/methodology/approach

This paper will provide an overview of the open source landscape and evaluate free and open source technologies of potential use in the college or university classroom.

Findings

The paper found a number of free and open source tools appropriate for teaching and learning in higher education. These tools may possibly generate savings over proprietary tools, but could have other costs such as additional learning investment or require hosting. Additionally, free and open source technologies provide students with knowledge about tools that they can continue to access after graduation. Libraries have a role in connecting their constituencies to these tools.

Originality/value

The paper provides descriptive information about a variety of tools for teaching and learning in higher education, as well as examples from the literature of how the tools might be integrated into the classroom and into library instruction.

Abstract

Purpose

A large amount of research deals with the identification of management practices related to new product development (NPD) success. To this purpose, assessment tools capable of helping enterprises to set up improvement processes are of extreme importance. The aim of this paper is to build a product development assessment model based upon a normativecontingent approach.

Design/methodology/approach

First, a literature review of the main approaches and models used in NPD assessment was carried out. Second, the tool was tested in five firms. The case studies allowed the authors to test the tool in its prototypal phase in order to assess both its limits and potential and also to highlight possible improvements.

Findings

The assessment tool developed yields a clear understanding of the current state of product development process in an organization in order to facilitate a shared understanding of the weakness and deficiencies, to enable effective process management, to develop implementation plan to support change initiatives and to support process improvement using metrics.

Originality/value

The product development assessment model is based upon a normativecontingent approach meaning that the prescriptive requirements are defined according to the logic of coherence: requirements vary in relation to contextual conditions. In particular, there are two important context factors which are considered to have a significant influence on NPD process: the complexity of the productmarket interface and the enterprise's NPD strategic orientations.

Abstract

Purpose

Arguably the most distinguishing characteristic of the current rise of foresight for dealing with the long term is the explicit mention and involvement of actors and actor networks, i.e. participation. In general, this participation dimension is considered a valuable contribution to better anticipation and anticipatory behavior. However, participation should not be seen as the solution for the conceptual and practical difficulties of anticipation. This paper seeks to argue that, although participation is a necessary requirement for foresight, it contributes a number of new problems, which one prefers to see as dilemmas (since there is no solution to theseproblems”). Understanding theseten insolvable dilemmas of participationis the main objective of this contribution.

Design/methodology/approach

This article employs theories and practice dealing with participatory approaches.

Findings

Although an important dimension of foresight, participation is often trivialized. However, using participation means also having to address new challenges for which no default design answer is possible.

Practical implications

Futures practitioners will be aware of the consequences of incorporating a participatory dimension into a foresight exercise.

Originality/value

Although participation has become a key feature of many contemporary foresight activities, generic design questions are either ignored or dealt with on a casetocase basis. This paper is an attempt to employ the body of theories on participation and participatory approaches in order to frame the participatory dimension in foresight.

Abstract

Purpose

The purpose of this paper is to propose a new conceptual framework for big data analytics (BDA) in the healthcare sector for the European Mediterranean region. The objective of this new conceptual framework is to improve the health conditions in a dynamic region characterized by the appearance of new diseases.

Design/methodology/approach

This study presents a new conceptual framework that could be employed in the European Mediterranean healthcare sector. Practically, this study can enhance medical services, taking smart decisions based on accurate data for healthcare and, finally, reducing the medical treatment costs, thanks to data quality control.

Findings

This research proposes a new conceptual framework for BDA in the healthcare sector that could be integrated in the European Mediterranean region. This framework introduces the big data quality (BDQ) module to filter and clean data that are provided from different European data sources. The BDQ module acts in a loop mode where bad data are redirected to their data source (e.g. European Centre for Disease Prevention and Control, university hospitals) to be corrected to improve the overall data quality in the proposed framework. Finally, clean data are directed to the BDA to take quick efficient decisions involving all the concerned stakeholders.

Practical implications

This study proposes a new conceptual framework for executives in the healthcare sector to improve the decision-making process, decrease operational costs, enhance management performance and save human lives.

Originality/value

This study focused on big data management and BDQ in the European Mediterranean healthcare sector as a broadly considered fundamental condition for the quality of medical services and conditions.

Abstract

The wetting performance and intermetallic formation of a Sn/Ag/Cu alloy on printed circuit board (PCB) surfaces and on component terminations were studied in this work. Two different PCB surface finishes, immersion gold over electroless nickel (Ni/Au) and an organic solderability preservative (OSP), were studied. Chip components with Sn/Pb coating and a gullwing type component with 100% Sn coating were used in these experiments. Different reflow profiles were tested, and the dependence of the wetting performance, intermetallic layer thickness and the microstructure of the solder joints on the reflow profile were investigated.It was found that reflow process conditions did not significantly influence the spreading or intermetallic formation on either of the surfaces. Neither the wetting onto the component nor the general microstructure of the solder joints varied significantly with the reflow profile. When a Sn/Pbcoated component was used, the content and size of Pbrich phases in the solder joint increased with a longer time above liquidus or a higher reflow peak temperature.

Abstract

Purpose

At the moment, business intelligence (BI) is known as the way for analyzing data in an organization. Simple search in the literature shows that there are many papers which discuss about BI applications and related matters. In addition, there are different approaches and tools that support using BI in organizations. This paper aims to focus on the use of BI tools for academic applications, and it describes how the academic area will benefit from using BI.

Design/methodology/approach

This paper is based on using BI tools and other library studies.

Findings

A process for using BI tools in academic applications has been presented. Also, two cases are stated about activities of e-learning participants and literature analysis, for which BI tools are used to analyze data and simplify difficult tasks.

Originality/value

This paper shows how BI tools can be used for research and academic applications.
