Abstract

The recently developed Reduced Oxide Soldering Activation (ROSA™) method is shown to be compatible with long‐term use with mass soldering processes. Prototype regeneration cells operated for as long as six months with minimal maintenance retained their effectiveness for providing short wetting times under a variety of perturbations. The operating window for the process is wide and component degradation caused by exposure to the fully charged solution is minimal. The ROSA treatment provides soldering performance comparable to that attainable with a fully activated rosin flux and offers the promise of providing low soldering defect rates without the use of CFC solvents.

Abstract

The sequential electrochemical reduction analysis (SERA) method was evaluated in production and demonstrated to provide a non‐destructive, objective measure of the solderability of production printed wiring boards. Approximately 1000 boards were analysed just before wave soldering and the SERA parameters were correlated with the soldering defect occurrence rates. The data show that PWB solderability is determined primarily by the nature of the surface tin oxide, as reflected in the corresponding SERA plateau voltage, rather than by the oxide thickness. By proper choice of the value of the plateau voltage used as the criterion for solderability, the most advantageous trade‐off between the costs of rejected boards and the rework of defects can be made.

Abstract

Fluxless wave soldering in a nitrogen atmosphere was investigated for epoxy‐fibreglass circuit board coupons having bare copper and solder‐coated through‐holes. The Reduced Oxide Soldering Activation (ROSA™) pretreatment was found to consistently provide good hole filling and through‐hole solder joints of excellent appearance. For preheated coupons, low levels of residual oxygen and short exposure to air after the ROSA treatment were found to have no effect

Abstract

This paper, based on forty in‐depth interviews with teachers and principals in Hong Kong, utilizes the insights of feminist organization studies to explore the persistence of gender inequalities in primary school teaching. Two common practices, namely the assignment of women and men to teach lower and higher grades respectively and the monopoly of men in positions of disciplining and authority, are centered. The data suggest that schools and teachers actively construct and reproduce gender inequalities by trivializing teaching of young children as babysitting, naturalizing women as natural caregivers, and normalizing the use of threat in disciplinary control. My analysis also argues that these routine and pervasive gendering processes are not often acknowledged or challenged, which have the effects of marginalizing caring work, overlooking the emotional labor of women, valorizing a masculine view of authority, encouraging men and boys to compete for power via aggression, and hence producing a masculinist workplace.

Abstract

The Pathways Commission on Accounting Higher Education Report (2012) recommends turning the accounting profession into a learned profession through the purposeful integration of accounting research, education and practice. This paper develops an approach to identifying and quantifying the specific dimensions of the gap between the accounting academic and practice communities, thereby contributing to moving the accounting profession to a learned profession. For this we focus on audit research, because the discussion of the perceived gap between audit research and audit practice is extensive; yet no one has actually quantified that gap to date. While researchers have classified and quantified audit research, no one has done likewise for publications issued by the practice community. We choose the 38 distinct recommendations in the Advisory Committee on the Auditing Profession (ACAP) Final Report as an initial benchmark. We compare those recommendations to the 16 audit research themes from Lesage and Wechtler (2012) and to the publications spanning 33 years of audit research posted on the American Accounting Association website. Eight Lesage and Wechtler themes, comprising 50% of the themes, were not explicitly included in any ACAP distinct recommendation. Conversely, seven distinct recommendations had zero direct matches in the audit literature. This gap suggests future research opportunities in terms of exploring underrepresented topics and, maybe more importantly, the reasons why some topics are underrepresented.

Abstract

The unique advantages of confocal microscopy are used to explore four cases of interest: (i) voids in solder (depth and surface texture determined), (ii) steam vs ambient aged solder coupons (significant differences detected), (iii) integrated circuit construction (sub‐surface contamination by µm‐size particles observed) and (iv) circuit boards and solder pads (non‐destructive optical sectioning through no‐wash flux layers). It is shown that confocal microscopy strongly complements SEM (scanning electron microscopy); SEM alone presents an incomplete description of a solder surface and in fact can sometimes produce misleading results.

Abstract

The more recent history of the National Health Service, especially the Hospital Service, has been in the nature of a lumbering from one crisis to another. From the moment of its inception it has proved far more costly than estimated and over‐administered, but in the early years, it had great promise and was efficient at ward level, which continued until more recent times. As costs increased and administration grew and grew, much of it serving no useful purpose, there appeared to be a need for reorganisation. In 1974, a three‐tier structure was introduced by the establishment of new area health authorities, the primary object of which was to facilitate — and cheapen — decision making; to give the district bodies and personnel easier access to “management”. It coincided with reorganisation of Local Government, which included the transfer of all the personal health services and abolition of the office of medical officer of health. At the time and in looking back, there was very little need for this and reviewing the progress and advances made in local government, medical officers of health who had advocated the transfer, mainly for reasons of their own status, would have achieved this and more by remainining in the local government service; the majority of health visitors appear to have reached the same conclusion. They constitute a profession within themselves and in truth do not have all that much in common with day‐to‐day nursing. The basic training and nursing qualification is most essential, however. It has been said that a person is only as good a health visitor as she is a nurse.

Abstract

Purpose

Rice agroecosystems must grow sustainably to meet the increasing demand for food. A fish-rice co-culture was introduced to conserve rice agroecosystems in farming communities. This study aims to assess the technical, socio-economic and environmental outcomes as the pillars of sustainability.

Design/methodology/approach

This study employs a mixed qualitative-quantitative approach to assess a sustainable intensification programme's impact on sustainability. Data were collected using group discussions and self-assessment surveys. The study sites cover East Java and West Java provinces.

Findings

This study found that rice-fish co-culture improved the sustainability of the farming system. Farmers applied pest and disease management and partially substituted inorganic fertilisers with organic ones. The outcomes were apparent in the diversity of harvested products. Economically, the rice yield increased, the production costs decreased and the resultant increased income. Environmentally, the fish-rice co-culture was sound because of ecological inputs. The population of natural enemies of pests increased. Socially, fish-rice co-culture was acceptable to the community since there was no conflict with the local governments, local norms and religions and the existing farming practices of other crops.

Research limitations/implications

This study was based on five groups as case studies, such that the result might not represent the general condition.

Originality/value

The study's methodology was supported by valid economic theories and data directly gathered from farmers.
