The Impact

In today’s competitive market providing products only in low cost and high quality is not enough.  Environmental concern in manufacturing is also an important issue now. To attract investors and customers organizations need to practice environmental manufacturing. This study is focused to present the relationships between some specific environmental manufacturing practices and their relative specific competitive outcomes in the important and vast industry of garment’s knitting sector in Bangladesh. Although there are several studies on the impact of environmental practices on the organizations outcomes but they are less construable due to many limitations. This study explores the environmental manufacturing practices under two categories pollution prevention and product stewardship and shows their relative competitive outcomes and establishes the relation between them. Based on the surveys and research it is found that some competitive outcomes are positively affected by some of the practices. These findings are believed to motivate the companies to turn towards the green manufacturing.

Production Decision

PurposeEquipment reliability significantly impacts productivity, and in order to obtain high equipment reliability and productivity, maintenance and production decision should be made simultaneously to keep manufacturing system healthy. The purpose of this paper is to investigate the joint optimization of equipment maintenance and production decision fork-out-of-nsystem equipment with attenuation of product quality and to explore the impact of maintenance on the production and cost control for manufacturers.Design/methodology/approachA multi-period Markov chain model fork-out-of-nsystem equipment is set up based on the assumption that the deterioration of equipment is a pure birth process. Then, the maintenance cost, setup cost, inventory holding cost, shortage cost, production cost and the quality cost are analyzed with the uncertain demand and the attenuation of product quality stemmed from equipment deterioration. The total lowest cost per unit time and its specific calculation method are presented. Finally, the robustness and flexibility of the method are verified by a numerical example and the effects of equipment deterioration intensity and attenuation of product quality are analyzed.FindingsThe result shows that the joint decision model could not only satisfy the uncertain demand with low cost and strong robustness but also make the output products high quality level. In addition, the attenuation of product quality would influence the equipment maintenance and production decision and leads to the production waste and increases the operation cost greatly.Originality/valueImplications derived from this study can help production maintenance managers and reliability engineers adequately select maintenance policy to improve the equipment efficiency and productivity with high quality level at a relatively low cost.

The Impact

Based on the different movement characteristics of macro-particles, ions and electrons in the plasma transmission, this paper developed a simple, easy device with low cost-- double dislocation perforated shielding plate used in the coupling enhanced magnetic field, which can also satisfy the requirements of preparing high-quality films; This paper also studied the impact of double dislocation perforated shielding plate on the transmission of arc plasma and film properties. The results showed that: compared with the physical fielding plate, in the realization of the resistance to macro-particles transferred in straight line, part of the ions can also pass through the perforated position in the double dislocation perforated shielding plate to increase the ion density behind the fielding plate, thus increasing the film’s deposition rate to some extent. At the same time, the double dislocation perforated shielding plate can significantly reduce the roughness of the film and improve the film's finish, while the film structure does not change.

The Impact

Amorphous silicon PECVD photonic integrated devices are promising candidates for low cost sensing applications. This manuscript reports a simulation analysis about the impact on the overall efficiency caused by the lithography imperfections in the deposition process. The tolerance to the fabrication defects of a photonic sensor based on surface plasmonic resonance is analysed. The simulations are performed with FDTD and BPM algorithms. The device is a plasmonic interferometer composed by an a-Si:H waveguide covered by a thin gold layer. The sensing analysis is performed by equally splitting the input light into two arms, allowing the sensor to be calibrated by its reference arm. Two different 1 × 2 power splitter configurations are presented: a directional coupler and a multimode interference splitter. The waveguide sidewall roughness is considered as the major negative effect caused by deposition imperfections. The simulation results show that plasmonic effects can be excited in the interferometric waveguide structure, allowing a sensing device with enough sensitivity to support the functioning of a bio sensor for high throughput screening. In addition, the good tolerance to the waveguide wall roughness, points out the PECVD deposition technique as reliable method for the overall sensor system to be produced in a low-cost system. The large area deposition of photonics structures, allowed by the PECVD method, can be explored to design a multiplexed system for analysis of multiple biomarkers to further increase the tolerance to fabrication defects.

Abstract: Scholarly publishing and access to high-quality information may in fact be threatened, rather than improved, by the revolution in communications, particularly in a fully commercial Internet. The effects of the political revolution in Eastern Europe on scholarship and quality publishing are used as a touchstone of the dangers that occur when naïve revolutionaries make swift changes without fully recognizing the impact upon delicately balanced social institutions such as non-profit organizations. Résumé: La révolution en communications, particulièrement en ce qui regarde un Internet commercialisé, plutôt que d'améliorer l'édition savante et l'accès à de l'information de haute qualité, pourrait en fait poser une menace pour ceux-ci. Cet article examine comment la révolution politique en Europe de l'Est a influé sur la recherche et l'édition de qualité. Il utilise cet exemple pour examiner les dangers que peuvent courir certains révolutionnaires naïfs quand ils instaurent des changements rapides san songer à leur impact sur des institutions sociales à équilibre délicat comme les organisations à but non lucratif.

SYNOPSIS Mandatory existence disclosure rules require an organization to disclose a policy's existence, but not its content. We examine policy adoption frequencies in the year immediately after the IRS required mandatory existence disclosure by nonprofits of various governance policies. We also examine adoption frequencies in the year of the subsequent change from mandatory existence disclosure to a disclose-and-explain regime that required supplemental disclosures about the content and implementation of conflict of interest policies. Our results suggest that in areas where there is unclear regulatory authority, mandatory existence disclosure is an effective and low cost regulatory device for encouraging the adoption of policies desired by regulators, provided those policies are cost-effective for regulated firms to implement. In addition, we find that disclose-and-explain regulatory regimes provide stronger incentives for policy adoption than do mandatory existence disclosure regimes and also discourage “check the box” behavior. Future research should examine the impact of mandatory existence disclosure rules in the year that the regulation is implemented.

Quality Theory

SUMMARY We insert an automated high-quality (HQ) auditor into established experimental audit markets to test the impact of high-quality competition on other auditors' supply of and managers' demand for audit quality. Theory predicts that managers will demand high levels of audit quality to avoid investors' price-protecting behavior. This demand should result in the HQ auditor dominating the market and increase other auditors' audit quality provision to compete with the HQ auditor. However, we find that the HQ auditor does not dominate the market—despite holding audit costs constant and investors placing a premium on HQ auditor reports. We also find that adding an HQ auditor results in other auditors lowering audit quality. Additional analyses indicate some managers demand lower audit quality to avoid negative audit reports, consistent with loss aversion as a potential explanation. Our findings indicate a need to develop a more comprehensive theory of the demand for auditing.
