Abstract

Purpose

The purpose of this paper is to study the melting temperature of the nanoparticles of the new developed Sn‐0.4Co‐0.7Cu (wt%) lead‐free solder alloy.

Design/methodology/approach

Nanoparticles of Sn‐0.4Co‐0.7Cu lead‐free solder alloy were prepared by the self‐developed consumable‐electrode direct current arc technique, where ultrasonic vibration was applied during the manufacturing of the particles. X‐ray diffraction and field emission scanning electron microscope were employed to analyze the crystal structure and morphology of the nanopartiles, respectively. Differential scanning calorimetry was used to investigate the melting temperature of both the bulk alloy and as‐prepared nanoparticles.

Findings

The melting temperature of the nanoparticles was approximately 5°C lower compared to that of the bulk alloy.

Originality/value

As a novel developed lead‐free solder alloy, the Sn‐0.4Co‐0.7Cu (wt%) alloy provides a cost advantage compared to the extensively used Sn‐Ag‐Cu system. Some limitations still exist, however, mainly due to its relatively higher melting temperature compared to that of eutectic Sn‐37Pb solder. In view of this situation, the attempt to lower its melting temperature has recently attracted more attention based on the knowledge that the melting temperature for pure metals is reduced when the particle size is decreased down to a few tens of nanometers.

Abstract

Purpose

Quality improvement has developed and spread, and today, all Swedish Regions emphasize that their strategies are based on systematic improvement. This paper aims to describe and illuminate the development of Quality Improvement (QI) in Swedish healthcare and welfare organizations by using publications in a Swedish context.

Design/methodology/approach

The overview synthesis is inspired by a scoping literature review approach of relevant literature. All publications relevant to Swedish healthcare and welfare settings between 1992 until 2020 were included.

Findings

In all, 213 papers, 29 books and chapters and 34 dissertations related to QI and research in Swedish healthcare and welfare context were identified. From 2011 to 2020, the publication rate increased rapidly. Six different focus areas emerged: systematic and value-creating improvement work; collaboration between organizations and healthcare providers; use of improvement methods and (theoretical) models; leadership and learning; measurements, quality registers and follow-up; and involvement and patient safety. Further QI development in Swedish healthcare and welfare points to an increased importance of collaboration between organizations and coproduction with beneficiaries for the healthcare and welfare services.

Originality/value

This paper is one of the first to describe and illuminate the QI development in the healthcare and welfare sector in a country. The trajectory also points to a need for coproduction to handle future challenges.

Abstract

Purpose

The purpose of this paper is to assess the effect of different temperature cycling profiles on the reliability of lead‐free 388 plastic ball grid array (PBGA) packages and to deeply understand crack initiation and propagation.

Design/methodology/approach

Temperature cycling of Sn‐3.8Ag‐0.7Cu PBGA packages was carried out at two temperature profiles, the first ranging between −55°C and 100°C (TC1) and the second between 0°C and 100°C (TC2). Crack initiation and propagation was analyzed periodically and totally 7,000 cycles were run for TC1 and 14,500 for TC2. Finite element modeling (FEM), for the analysis of strain and stress, was used to corroborate the experimental results.

Findings

The paper finds that TC1 had a characteristic life of 5,415 cycles and TC2 of 14,094 cycles, resulting in an acceleration factor of 2.6 between both profiles. Cracks were first visible for TC1, after 2,500 cycles, and only after 4,000 cycles for TC2. The crack propagation rate was faster for TC1 compared to TC2, and faster at the package side compared to the substrate side. The difference in crack propagation rate between the package side and substrate side was much larger for TC1 compared to TC2. Cracks developed first at the package side, and were also larger compared to the substrate side. The Cu tracks on the substrate side affected the crack propagation sites and behaved as SMD. All cracks propagated through the solder and crack propagation was mainly intergranular. Crack propagation was very random and did not follow the distance to neutral point (DNP) theory. FEM corroborated the experimental results, showing both the same critical location of highest creep strain and the independence of DNP.

Originality/value

Such extensive work on the reliability assessment of Pb‐free 388 PBGA packages has never been performed. This work also corroborates the results from other studies showing the difference in behavior between Pb‐free and Pb‐containing alloys.

Abstract

Purpose

Early identification of persons at risk is essential in suicide prevention. Undocumented migrants (UM) live under limited conditions and are to a high degree invisible, both in research and in suicide prevention programmes. The aim of this study was to investigate prevalence rates of suicidal thoughts among UM in Sweden.

Design/methodology/approach

This cross-sectional study was part of the Swedish Health Research on Undocumented Migrants project (SHERUM). The study population consisted of 104 UM over 18 years of age recruited through informal networks. Data on 112 multiple choice questions was collected via trained interviewers in Gothenburg, Stockholm and Malmö during 2014–2016. To assess suicidal thoughts (the last two weeks) one item asking about suicidal thought in the Beck Depression Inventory scale (BDI-II) was used. Logistic regression and chi-square analyses were made to identify risk and protective factors.

Findings

Suicidal thoughts were found in 43.2% of the 88 UM that answered the question on suicidal thoughts. Being a parent had some protective influence on the prevalence of suicidal thoughts while the housing situation, having been exposed to crime and having mental illness were all statistically significant risk factors for suicidal thoughts. However, due to low sample size, few variables presented statistically significant differences.

Originality/value

This study presents an alarmingly high prevalence of suicidal thoughts among undocumented migrants in Sweden, a difficult-to reach, vulnerable and rarely studied group. Targeted strategies are imperative to include undocumented migrants in suicidal prevention programmes.

Abstract

Workplace incivility has been identified as a specific form of social mistreatment causing distress despite its low intensity. Research on workplace incivility has touched on a variety of personal and contextual factors associated with incivility’s prevalence including research on both antecedents and outcomes. The research has been especially concerned with identifying a wide range of negative consequences of incivility, including various occupational, interpersonal, and health-related implications. Theoretical explorations have considered links of incivility to sexism and racism, and its reflection of attachment styles, as well as its inherent connection with the stressor-emotion model of counterproductive work behavior (Spector & Fox, 2005). The power of incivility to elicit distress has been attributed to its capacity to signal riskiness of social situations that thwart core social motives (i.e., self-control). Intervention research has been relatively rare, but progress is evident.

Abstract

Purpose

The purpose of this paper is to empirically explore and demonstrate the ability of healthcare professionals to attain professional fulfilment when providing healthcare inspired by “value shops”.

Design/methodology/approach

A qualitative case study incorporating interviews and observations was conducted.

Findings

The empirical data suggest that the professional fulfilment of both physicians and nurses is facilitated when care is organized through “value shops”. Both groups of professionals state that they are able to return to their “professional core”.

Originality/value

The beneficial outcomes of organizing healthcare inspired by the “value shop” have previously been explored in terms of efficiency and quality. However, the professional fulfilment of healthcare professionals when providing such care has not been explicitly addressed. Professional fulfilment is vital in order to safeguard high-quality care, as well as healthcare professionals' involvement and engagement in implementing quality improvements. This paper highlights the fact that care provision inspired by the “value shop” may facilitate professional fulfilment, which further strengthens the potential positive outcomes of the “value shop” when utilized in a healthcare setting.

Abstract

Purpose

The purpose of this study is to examine and establish how sensemaking develops among a group of external change agents (ECAs) engaged to disseminate a national quality register nationwide in Swedish health care and elderly care. To study the emergent sensemaking, the theoretical concept of cognitive shift has been used.

Design/methodology/approach

The data collection method included individual semi-structured interviews, and two sets of interviews (initial sensemaking and renewed sensemaking) have been conducted. Based on a typology describing how ECAs interpret their work, structural analyses and comparisons of initial and renewed sensemaking are made and illuminated in spider diagrams. The data are then analyzed to search for cognitive shifts.

Findings

The ECAs’ sensemaking develops. Three cognitive shifts are identified, and a new kind of issue-related cognitive shift, the outcome-related cognitive shift, is suggested. For the ECAs to customize their work, they need to be aware of how they interpret their own work and how these interpretations develop over time.

Originality/value

The study takes a novel view of the interrelated concepts of sensemaking and sensegivers and points out the cognitive shifts as a helpful theoretical concept to study how sensemaking develops.

Abstract

This study investigates the role of grit in a work setting as well as interrelationships among work-related constructs among frontline employees of hotels. Based on the framework of grit and work-related constructs, this study proposes and tests a model that attempts to understand the dynamic relationship among the two dimensions of grit, customer orientation, job satisfaction, and job performance, with an emphasis on the moderating role of organizational tenure. The results indicate that consistency of interest significantly influences customer orientation, whereas perseverance of effort significantly affects job satisfaction. Job performance is significantly influenced by customer orientation and job satisfaction. The paths from perseverance of effort to customer orientation, from perseverance of effort to job satisfaction, and from consistency of interest to job satisfaction are significantly moderated by organizational tenure.
