Abstract

Purpose

At present, over 95 percent of the manufactured packages are still being wire bonded. Owing to the ongoing trend of miniaturization, material changes, and cost reduction, wire bond‐related failures are becoming increasingly important. This paper aims to understand these kinds of failures.

Design/methodology/approach

Different finite element (FE) techniques are explored to their ability to describe the thermo‐mechanical behavior of the wire embedded in the electronic package. The developed nonlinear and parametric FE models are able to predict the strong nonlinear behavior of wire failures and multi‐failure mode interaction accurately and efficiently.

Findings

It is found that both processing and testing environments as well as the occurrence of delamination strongly increase the risk for wire failures. The results indicate that processing and testing influences are much less than those of the delamination.

Practical implications

Package designers should focus on limiting the occurrence of delamination around wire bond and/or stitch areas.

Originality/value

Combining the strengths of predictive modeling with simulation‐based optimization methods, the optimal wire shape is obtained.

Abstract

Purpose

This study analyzes the rise of genome instability in the life sciences and traces the problematic of instability as it relates to the sociology of health. Genome instability is the study of how genomes change and become variable between generations and within organisms over the life span. Genome instability reflects a significant departure from the Platonic genome imagined during the Human Genome Project. The aim of this chapter is to explain and analyze research on copy number variation and somatic mosaicism to consider the implications of these sciences for sociologists interested in genomics.

Methodology/approach

This chapter draws on two multi-sited ethnographies of contemporary biomedical science and literature in the sociology of health, science, and biomedicine to document a shift in thinking about the genome from fixed and universal to highly variable and influenced by time and context.

Findings

Genomic instability has become a framework for addressing how genomes change and become variable between generations and within organisms over the life span. Instability is a useful framework for analyzing changes in the life sciences in the post-genomic era.

Research implications

Genome instability requires life scientists to address how differences both within and between individuals articulate with shifting disease categories and classifications. For sociologists, these findings have implications for studies of identity, sociality, and clinical experience.

Originality/value

This is the first sociological analysis of genomic instability. It identifies practical and conceptual implications of genomic instability for life scientists and helps sociologists delineate new approaches to the study of genomics in the post-genomic era.

Abstract

Purpose

The traditional value chain has changed under the influence of globalisation, lean thinking and the value leverage towards suppliers in the supply chain. The leverage of value by the focal original equipment manufacturer (OEM)‐company to the supply chain has caused the focal OEM‐company to transform into a large‐scale system integrator (LSSI). The LSSI was defined according to the Petrick's definition. Indicators that measure the value‐leverage by these LSSI companies have not been found in literature. The purpose of this paper is to describe indicators that measure value‐leverage and illustrates that LSSI companies in the aerospace industry have a value‐leverage capability, using these indicators.

Design/methodology/approach

The authors' main research question is: “How to measure value‐leverage by LSSIs in the aerospace industry?”. As value‐leverage indicators have not been studied before, a literature study was carried out to develop a set of indicators which were tested in a quantitative analysis, using secondary data from 41 aerospace companies. Second, the value‐leverage indicators were applied to the aircraft LSSIs. The industry samples consisted of the global companies in the aircraft OEM industry and the relevant financial and company data were collected from the companies' public financial data, spanning a time frame of 14 years (1996 to 2009). A case study was performed on large‐scale aircraft system integrators, as a sample of the aerospace OEM industry, to demonstrate the effects of value‐leverage by aircraft LSSI companies.

Findings

With the new indicators, this research shows value leverage of aerospace OEMs and aircraft LSSIs as a sub group of the sample. The related indicators showed a change in leverage over time, indicating the leverage capability of aerospace OEMs. More in‐depth analysis on aircraft LSSI companies showed that aircraft LSSI with high correlation on the value‐leverage variables are more in value balance compared with aircraft LSSI companies scoring lower on the variables.

Research limitations/implications

This research has been limited to the aerospace OEMs. Data from secondary (public) sources were used, such as financial reports over a period of 14 years. Further research is necessary to develop indicators for other sectors of industries, such as automotive, medical instruments and construction, as well as to further improve the understanding of the outcomes of this study.

Practical implications

The new indicators measure value‐leverage of aerospace OEMs in general and aircraft LSSI companies. These companies could be compared on their capability of value‐leverage. Management of these firms can use the indicators to further improve their capability of value‐leverage on the supply chain regarding co‐development and co‐production of aircraft and related systems.

Social implications

It is useful for the executive management of aircraft LSSIs to balance the value leverage of their companies regarding R&D, customer demand and supply chain based production.

Originality/value

The paper identifies indicators that measure the capability of the aerospace OEMs to leverage value on supply chains. The found indicators form a preliminary model, which contributes to the usage of theories on lean manufacturing, supply chain management, value networks and open innovation.

Abstract

This chapter explores how stress may manifest among non-family member employees, family member employees, and family firm founders in family firms during the startup phases of the organization. Understanding how stress arises in family firm startups has received limited attention to date. Notably absent in the research is the understanding of how stress arises in non-family member employees, which is important to understand as non-family member employees often outnumber family member employees. As stress increases for the non-family member employee due to issues such as role ambiguity and conflict, negative outcomes resultant from this stress may increase the chances of the employee exhibiting withdrawal behaviors. It is suggested these outcomes increase the stress of the family firm entrepreneur and family members by increasing interrole and interpersonal conflicts and negatively impacting decision-making. These effects on the family members may adversely impact the family firm’s chances of performing well, thus decreasing its chances for survival. Recommendations for future research are also made.

Abstract

The reported inquiry-based learning (IBL) study was designed in 2012–2013 for the highest achieving undergraduate students at a research-intensive university in the United Kingdom (U.K.). In 2005, the University received national funding from the U.K. Higher Education Academy (HEA) to develop an innovative model of IBL to be used in a multidisciplinary context (Tosey, 2006). As a consequence, IBL was an obvious tool when, in 2012, the authors set out to design learning interventions to improve the teamwork and leadership skills of high-attaining students. In the process of exploring the application of IBL to this task, the need to ensure the intervention allowed for development in the conative domain was considered important. Historically, IBL practice at the University had catered well for cognitive and affective learning but had not been focussed to develop conation. A conative-heavy element was therefore purposefully designed into the latest IBL intervention.

Abstract

Purpose

Current literature presents limited measurement methods of quantifying manufacturers' performance with environmental concerns. The purpose of this paper is to construct a company performance index for benchmarking motor vehicle manufacturers (MVMs) with environmental concerns.

Design/methodology/approach

Methods of constructing the index include regression analysis, a modified linear method for normalizing variables and a geometric mean for aggregating variables into a single index IMVM (index for MVMs). A case study is conducted in 12 MVMs from 2008 to 2017. A sensitivity analysis with the simple additive weighting method is performed to analyze how different aggregation methods affect the final value. The index IMVM is assessed through a benchmark with three existing indices.

Findings

Three realistic considerations are identified from MVMs, based on which proper and transparent methods are chosen to construct the IMVM. The construction of the index IMVM has been assessed through a benchmark against the methodologies of three other indices. The results indicate that the new measurement is feasible and effective for MVMs to measure their company performance from an environmental perspective.

Practical implications

The construction of the index IMVM can support policymakers with accurate statistics for decision-making. As a response to current imperative climate policies, this paper raises awareness of CO2 emissions in vehicles' production. For statistical organizations and stakeholders in the investment world, this paper provides available and reliable statistics for trend analysis of different MVMs.

Originality/value

A new method is designed for constructing a company performance index for MVMs. Three environmental variables are identified based on literature, their environmental impact as well as their data availability from public documents. A ranking by manufacturer with environmental concerns is generated. This index can contribute with available statistics and useful insights toward decision-making.

Abstract

Trends in the car and aircraft manufacturing industry showed an evolution in the configuration and management of the production network. For instance, the aerospace manufacturing industry tended to be a closed system, competing on scale of production and focusing on maximization of own profit. Nowadays the automotive companies are developing open systems under the influence of globalization, outsourcing, and co-creation of value. Doing this with suppliers causes a shift of value from the focal firm to the supply chain, creating a value levering position for the so-called large-scale system integrator (LSSI). The leverage of value on suppliers introduces the value-leverage capability of the LSSI company. The capability of the LSSI to balance continuation, conception, and configuration is crucial for (long-term) profitability and competitive position. To express the value-leverage capabilities, the authors propose the variables “turnover per employee” (T/E), “research and development per employee” (RD/E), and “profit per employee” (P/E), whose (inter) relationship determines the capabilities.
