Abstract

Purpose

This study aims to solder AlN ceramics with a Cu substrate using an active type Sn-Ag-Ti solder. Soldering was performed with power ultrasound. The Sn3.5Ag2Ti alloy was first studied.

Design/methodology/approach

It was found to contain a Sn matrix, where both Ag phase – ɛ-Ag3Sn – and Ti phases ɛ-Ti6Sn5 and Ti2Sn3 – were identified. Ti contained in these phases is distributed to the interface with ceramic material. A reaction layer was thus formed. This layer varies in thickness from 0.5 to 3.5 µm and ensures the wettability of an active solder on the surfaces of ceramic materials.

Findings

X-ray diffraction analysis proved the presence of new NTi and AlTi2 phases on the fractured surface. Sn plays the main role in bond formation when soldering the Cu substrate with Sn-Ag-Ti solder. The Cu3Sn and Cu6Sn5 phases, which grow in direction from the phase interface to solder matrix, were found in all cases within the solder/Cu substrate interface. The combination of AlN ceramics/Cu joint maintained a shear strength of 29.5 MPa, whereas the Cu/Cu joint showed a somewhat higher shear strength of 39.5 MPa.

Originality/value

The present study was oriented towards soldering of AlN ceramics with a Cu substrate by the aid of ultrasound, and the fluxless soldering method was applied. Soldering alloy type Sn-Ag-Ti was analysed, and the interactions between the solder and ceramic and/or Cu substrate were studied. The shear strength of fabricated soldered joints was measured.

Abstract

The Canadian mutual fund setting is unique in that two governance mechanisms – corporate and trust – coexist. This study empirically examines the impact of each mechanism on fund fees and performance. We find that corporate class funds charge higher fees but deliver superior fee-adjusted returns than trust funds. We then analyze the impact of various board characteristics on fees and performance for corporate class funds. We find that a board with smaller size, CEO duality, and a higher percentage of independent directors is more likely to charge lower fees. In addition, smaller boards are strongly associated with higher fee-adjusted performance. Our study supports agency theory over stewardship theory and provides valuable guidelines for Canadian investors and regulatory agencies.

The work aims to study the direct bonding of silicon substrate with solders type Sn-Ag-Ti.

Abstract

Purpose

The work aims to study the direct bonding of silicon substrate with solders type Sn-Ag-Ti.

Design/methodology/approach

During the bonding process with ultrasound assistance, the active element (Ti,Ce,Mg) is distributed from the solder to interface with a silicon substrate, where it supports the bond formation.

Findings

Formation of a reaction layer, 1-2 μm in thickness, was observed. The new Si2Ti phases and Mg2Si phase were identified in the reaction layer.

Originality/value

The results of analysis suggest that the Si/Sn-Ag-Ti joint is of diffusion character. The highest average strength on silicon substrate (39 MPa) was achieved with Sn-Ag-Ti(Mg) solder.

Abstract

Purpose

Circular economy (CE) has gained considerable attention from researchers and practitioners over the past few years because of its potential social and environmental benefits. However, limited attention has been given in the literature to explore the drivers and barriers in CE implementation in emerging and developing countries besides China. Therefore, the purpose of this paper is to identify the drivers and barriers to implementing a CE in Pakistan’s automobile manufacturing industry.

Design/methodology/approach

This study adopts an explorative approach to understand the drivers and barriers at the micro-level CE implementation in Pakistan’s automobile industry. The research design includes both qualitative and quantitative methods using a survey instrument and interviews to gather data. The use of the two main sources of data provides the opportunity for triangulation of the data to improve the validity of the findings, and enables greater inferences from the results.

Findings

This study shows that “profitability/market share/benefit” (30 percent), “cost reduction” (22 percent) and “business principle/concern for environment/appreciation” (19 percent) are the top three drivers. Similarly, “unawareness” (22 percent), “cost and financial constraint” (20 percent) and “lack of expertise” (17 percent) are the top three barriers in implementing CE principles in Pakistan automobiles industry.

Research limitations/implications

This study considers only Pakistan automobiles industry, and the practical implications potentially limit to emerging Asian economies.

Originality/value

This study is the first of its kind that has investigated the drivers and barriers of CE at the organizational level in the automobile industry of Pakistan. Thus, it helps to advance the understanding of the subject matter and enables the formulation of effective policies and business strategies by practitioners for upscaling CE and sustainability.

Abstract

Purpose

The purpose of this paper is to examine the relationship between neighbourhood characteristics and fear of crime, and further explore how this relationship is mediated by collective efficacy. The background to this is that while research, mainly based on the experiences of western countries is conclusive on how collective efficacy plays a mediating role between neighbourhood structural characteristics and fear of crime, the situation in developing countries remains poorly researched.

Design/methodology/approach

The study drew from a baseline survey conducted in different socio-economic neighbourhoods in four cities in Ghana. With regards to the analysis, results from a series of ordinary least square multiple regression models were used to develop a path diagram to explain the direct and indirect relationships at the various study neighbourhoods.

Findings

Results from the study showed variations of the extent of neighbourhood effect on fear of crime and collective efficacy in the different socio-economic neighbourhoods. More importantly, the study revealed that collective efficacy mediated the effect of a number of neighbourhood characteristics on fear of crime in low-income neighbourhoods compared to middle- and high-income neighbourhoods.

Practical implications

The conclusion of the study brings to the fore the relevance of collective efficacy as a vehicle for building safer communities in Ghana since it relies on local initiatives in addressing criminogenic problems. More importantly, it is suggested that formal crime prevention efforts should be integrated with informal crime control measures, particularly in low-income neighbourhoods.

Originality/value

Using extensive survey data collected in Ghana, the study examines the applicability of collective efficacy, a western-based socio-ecological theory in a developing country context.

Abstract

Purpose

The aim of this study is to identify and prioritize a list of key digitization enablers that can improve supply chain management (SCM). SCM is an important driver for organization's competitive advantage. The fierce competition in the market has forced companies to look the past conventional decision-making process, which is based on intuition and previous experience. The swift evolution of information technologies (ITs) and digitization tools has changed the scenario for many industries, including those involved in SCM.

Design/methodology/approach

The Best Worst Method (BWM) has been applied to evaluate, rank and prioritize the key digitization and IT enablers beneficial for the improvement of SC performance. The study also used additive value function to rank the organizations on their SC performance with respect to digitization enablers.

Findings

The total of 25 key enablers have been identified and ranked. The results revealed that “big data/data science skills”, “tracking and localization of products” and “appropriate and feasibility study for aiding the selection and adoption of big data technologies and techniques ” are the top three digitization and IT enablers that organizations need to focus much in order to improve their SC performance. The study also ranked the SC performance of the organizations based on digitization enablers.

Practical implications

The findings of this study will help the organizations to focus on certain digitization technologies in order to improve their SC performance. This study also provides an original framework for organizations to rank the key digitization enablers according to enablers relevant in their context and also to compare their performance with their counterparts.

Originality/value

This study seems to be the first of its kind in which 25 digitization enablers categorized in four main categories are ranked using a multi-criteria decision-making (MCDM) tool. This study is also first of its kind in ranking the organizations in their SC performance based on weights/ranks of digitization enablers.

Abstract

In response to the growing evidence that disruptive behaviors within health care teams constitute a major threat to the quality of care, the Joint Commission on Accreditation of Healthcare Organization (JCAHO; Joint Commission Resources, 2008) has a new leadership standard that addresses disruptive and inappropriate behaviors effective January 1, 2009. For professionals who work in human resources and organization development, these standards represent a clarion call to design and implement evidence-based interventions to create health care communities of respectful engagement that have zero tolerance for disruptive, uncivil, and intimidating behaviors by any professional. In this chapter, we will build an evidence-based argument that sustainable change must include organizational, team, and individual strategies across all professionals in the organization. We will then describe an intervention model – Toxic Organization Change System – that has emerged from our own research on toxic behaviors in the workplace (Kusy & Holloway, 2009) and provide examples of specific strategies that we have used to prevent and ameliorate toxic cultures.

Abstract

Purpose

Technology and knowledge have become the buzzwords of the new millennium. Technological changes and demanding customers are creating a more knowledge intensive, turbulent, complex and uncertain environment. Organizations, which are able to continually build faster and cheaper new strategic assets than their competitors, create long-term competitive advantages. Thus, the growth of companies is directly associated with innovativeness and technological development, especially for small organizations that are more vulnerable to dynamic changes in market place. Organizations need a strategic framework that can help them to achieve the goal of technology development and competitiveness. The purpose of this paper is to develop such strategic framework for small organizations for their technology development and, hence, survival in marketplace.

Design/methodology/approach

Options field methodology, options profile methodology, analytic hierarchy process (AHP) and fuzzy set theory are utilized to generate various options and profiles to propose a conceptual framework for technology development.

Findings

The results from the study showed that “mixed approach,” “strategic simulation approach” and the “regulatory environment approach,” in this order, emerged as the top three important options for the strategic technological development of small manufacturing enterprises.

Originality/value

This result can provide an original and more accurate implementation pathway toward technological innovative development in emerging economies. The proposed framework can provide valuable guidelines and recommendations to practicing managers and analysts for policy development to promote innovative and technological developments.
