Abstract
A study was conducted to examine the sensitivity of solder joint integrity for PBGA assembly and post rework process yields to the change of the solder ball coplanarity specification from 0.15mm to 0.20mm as well as to increase the level of confidence with respect to the specification change. The study considered the following experimental variables: solder ball coplanarity; stencil thickness and aperture design; whether the assembly also experiences a wave soldering process; the rework method, i.e. whether there is dispensing of solder paste or just a flux. Electrical continuity tests were performed after PBGA assembly and rework. Accelerated thermal cycling and thermal shock tests were then used to evaluate the solder joint reliability. Additionally, standoff heights of PBGA solder joints were measured through cross sectioning samples. Statistical comparisons of the mean standoff height between different PBGA coplanarity groups, where different experiment variables were applied, allowed for determination of the variation of BGA solder joint integrity.

Abstract
Purpose
To deepen our understanding about the development of turnover intention, the purpose of this paper is to develop a model that explains how ethical climate influences turnover intention based on the ethical climate theory and social identity theory.
Design/methodology/approach
The hypotheses of this study were statistically tested using a survey of working professionals from Taiwan’s high-tech industry. Of the 400 questionnaires distributed to the working professionals from five large high-tech firms in a well-known science park in Northern Taiwan, 352 usable questionnaires were returned for a questionnaire response rate of 88 percent.
Findings
The test results of this study first show that all three dimensions of ethical climate (i.e. instrumental, benevolent, and principled) are indirectly related to turnover intention via the mediation of firm attractiveness. Moreover, instrumental and benevolent climate directly relate to turnover intention, whereas benevolent climate negatively moderates the relationship between principled climate and firm attractiveness.
Originality/value
This study finds that benevolent climate plays a dual role as an antecedent and a moderator in the formation of turnover intention, complementing prior studies that merely concentrate on the single role of benevolent climate as either an antecedent or a moderator. The effect of principled climate on organizational identification complements the theoretical discussion by Victor and Cullen (1987) about deontology in which an ethical workplace climate (such as legitimacy) drives employees to invest in identity attachments to the organization and influences their future career decision (e.g. turnover).

Abstract
Gives an in depth view of the strategies pursued by the world’s leading chief executive officers in an attempt to provide guidance to new chief executives of today. Considers the marketing strategies employed, together with the organizational structures used and looks at the universal concepts that can be applied to any product. Uses anecdotal evidence to formulate a number of theories which can be used to compare your company with the best in the world. Presents initial survival strategies and then looks at ways companies can broaden their boundaries through manipulation and choice. Covers a huge variety of case studies and examples together with a substantial question and answer section.

Abstract
Develops an original 12‐step management of technology protocol and applies it to 51 applications which range from Du Pont’s failure in Nylon to the Single Online Trade Exchange for Auto Parts procurement by GM, Ford, Daimler‐Chrysler and Renault‐Nissan. Provides many case studies with regards to the adoption of technology and describes seven chief technology officer characteristics. Discusses common errors when companies invest in technology and considers the probabilities of success. Provides 175 questions and answers to reinforce the concepts introduced. States that this substantial journal is aimed primarily at the present and potential chief technology officer to assist their survival and success in national and international markets.

Abstract
Purpose
Previous research in auditing has used the probability of small profits or losses as a measure of audit quality. The purpose of this paper is to investigate the validity of the underlying assumption in prior audit literature that auditing mitigates clients’ inclination towards loss avoidance and to shed light on the debate regarding earnings discontinuity.
Design/methodology/approach
This paper compares the discontinuity in earnings distribution around zero, both before and after auditing.
Findings
Using a unique data set that contains both recorded and waived adjustments, the authors find that audit adjustments do not reduce the discontinuity in earnings distribution around zero.
Research limitations/implications
The results advise caution in using the probability of small profits or losses as a measure of audit quality. The findings suggest the discontinuity in earnings around zero may not be caused by loss avoidance achieved through accounting misreporting, which falls under the purview of auditing.
Originality/value
This research makes unique contributions beyond those of prior studies. By incorporating waived adjustments, the authors are able to conduct more comprehensive tests and explore richer details of audit adjustments that were not available in previous studies. The proportion of losses in this study's sample aligns with that in prior US research, which enhances the generalisability of the authors’ findings and minimizes the influence of inherent discrepancies in auditors' motivations to curb loss avoidance.

Abstract
All gender identity is socialized, but anything gendered feminine is marginalized. In the United States, we live in a patriarchal culture that is bounded by binary gender identity. Up to this point, work on gender and education leadership has remained within the bounds of patriarchy, and thus been confined to binary, hierarchical gender definitions. This study pushes past prior work to advance a more complex and messy understanding of how identity impacts aspiring leaders in their careers. Using Carol Gilligan and Snider (2018) Listening Guide Method, this study of 18 aspiring school leaders of different gender identities, sexual identities, and races focuses on how gender identity and gender performance impact school leaders' career trajectories. A key finding of this study is that women, regardless of race or sexual identity, have difficulty finding mentors while men, regardless of race or sexual identity, are tapped by schools leaders and offered mentoring opportunities. This chapter posits a new framework for mentoring that will lead to more liberatory pipeline structures.
