Abstract

Purpose

The purpose of this paper is to develop simulation models for flexible‐printed circuit boards' flex‐rigid interfaces and to perform experimental tests in the laboratory in order to evaluate the cracking phenomena when these devices are submitted to thermal cycling.

Design/methodology/approach

A device was proposed in order to evaluate the reliability of flex‐rigid interconnections. Thermal cycling tests were performed in an environmental chamber and failure mechanisms investigated using optical and scanning electron microscope techniques. The failure modes were analyzed using computational modelling via the finite element method.

Findings

Through failure analysis, it was observed that device design and thermal expansion/contraction could contribute to the occurrence of high stresses in the copper pad connections. The simulation model proposed was able to identify the critical regions, as they had occurred in the tests. Thus, the qualitative approach may be considered successful enough to be applied in the early stages of design.

Research limitations/implications

The materials proprieties were considered as being linear. Thus, in order to enhance the simulation models to provide a quantitative model for the evaluation of product life, non‐linear (visco‐elastic) behaviour in the material properties and a fracture model should be considered.

Originality/value

Typical causes of cracking failure in electronic devices are related to mechanical stress, moisture, heat from transportation and field use. Thus, finite element analysis is an important tool in order to evaluate the reliability of electronic components regarding these types of loads in the early stages of design.

Abstract

Purpose

This paper aims to critically review the most cited literature published from 2000 to 2020 in 24 top-ranked marketing journals on the three most studied branding concepts of the 21st century – brand equity, brand loyalty and brand image – to explore how in these papers they have been defined, measured and examined, and propose how they should move forward in an era where brands are expected to be “socially and socio-politically conscious.”

Design/methodology/approach

For each concept a systematic literature review is conducted. In doing so, the definitions, antecedents, outcomes and measures for each concept were accessed and synthesized.

Findings

The systematic literature reviews provide a “state-of-the-art” snapshot of each concept and collectively demonstrate there is no consensus on the independence and interdependence of these dynamic multidimensional concepts. Based on the recommended process in the measurement literature, an evolved definition of each concept is proposed. In addition to the corresponding research directions presented in the moving forward sections of each systematic literature review, common research avenues emerged.

Originality/value

This paper acknowledges these three branding concepts as dynamic (i.e. evolving over time), systemically reviews and synthesizes the extant literature, and provides a path forward to defining, measuring and exploring brand equity, brand loyalty and brand image in the present era where brands are expected to be socially and socio-politically conscious with responsibilities to the planet, people and profit.

Abstract

Purpose

This study investigates the corruption practices from a behavioral perspective, and aims to verify the impact of health Management Information System (MIS) institutionalization on corruption vulnerabilities and the intention to commit corruption. The studied vulnerabilities are related to management: lack of internal control, accountability, transparency and disburdened administration. This study was conducted in the Brazilian public health system.

Design/methodology/approach

A research model and instrument were created based on the literature. The model was later tested using the partial least squares technique. A survey of 355 valid responses followed a pilot test with 87 ones. The respondents were civil servants of the Brazilian public health system.

Findings

Seven of the eight hypotheses were confirmed, supporting the main hypothesis that MIS institutionalization impacts individuals’ behavior by reducing their intention to commit corruption. Institutionalized health MIS improves public management, enabling the prevention of favoritism when awarding service provision contracts, undue payments to corrupt employees and waste of medical and hospital supplies.

Originality/value

This research adds to the knowledge on corruption from an individual’s behavior perspective influenced by MIS institutionalization in a Latin American perspective. Corruption is a social and cultural-based phenomenon, which reinforces the importance of understanding the effect of Information Systems institutionalization on corruption vulnerabilities in this context. A research model and instrument were created and validated, confirming corruption vulnerabilities that influence behavior. The intention to commit corruption is reduced when mediated by institutionalized MIS. Consequently, the focus must be shifted from moral beliefs to creating and strengthening organizational capacity to systematically identify and reduce vulnerabilities and deter misbehavior and wrongdoings.
