Market Strategies

SummaryThis paper shows - in contrast to the literature on excess capacity - that capacity commitment can improve market allocations, if network externalities are present. Intertemporal network externalities can lead to a large degree of misallocation in simple markets. However, the attempt of firms to appropriate the potential surplus from standardization generates new market strategies as e.g. capacity commitment that can mitigate the standardization problem. In this context, capacity does not incorporate the detrimental effects stated in the excess capacity literature, but guarantees the functioning of markets in the interest of collective rationality. The relevance of this strategy in markets with network externalities is illustrated by the emergence of VCR standards.

Semiconducting Diamond

Semiconducting diamond films have the potential for use as a material in which to build active electronic devices capable of operating at high temperatures or in high radiation environments. A major goal of current device-related diamond research is to achieve a high quality epitaxial film on an inexpensive, readily available, non-native substrate. One step in the process of achieving this goal is understanding the nucleation and growth processes of diamond films on diamond substrates. Electron microscopy has already proven invaluable for assessing polycrystalline diamond films grown on nonnative surfaces.The quality of the grown diamond film depends on several factors, one of which is the quality of the diamond substrate. Substrates commercially available today have often been found to have scratched surfaces resulting from the polishing process (Fig. 1a). Electron beam-induced current (EBIC) imaging shows that electrically active sub-surface defects can be present to a large degree (Fig. 1c). Growth of homoepitaxial diamond films by rf plasma-enhanced chemical vapor deposition (PECVD) has been found to planarize the scratched substrate surface (Fig. 1b).

Subject. The article focuses on market strategies of the Russian enterprises operating in the ferrous metallurgy. Objectives. The study is to analyze corporate strategies the leading ferrous metal manufacturers use in the Russian Federation, such as NLMK Group, Severstal, Magnitogorsk Iron & Steel Works, EVRAZ Group. Methods. The study interprets public financial statements and methods of the logic, intuitive and comparative analysis. Results. We analyze market strategies of the Russian metal manufacturers, determine their development priorities and competitive advantages and weaknesses. We describe the impact of various threats and measures metallurgical companies undertake to eliminate them. Conclusions and Relevance. We sorted out possible threats and exposures of the Russian metallurgic companies' economic security and traced the dynamics of their significance for 2015 to 2019. Key threats relate to policies, economy, external and internal market, regulations and laws, production, distribution and financial management, consumption, IT, social welfare and environment.

Training Service

Improving the quality in order to keep up with the trend in the world is the vital task of training institutions today. Training institutions need to grasp market needs and satisfy the requirements of customers - learners. Nadiri, H., Kandampully, J & Hussain, K. (2009) argue that the managers in education need to apply market strategies that are being used by manufacturing and business enterprises and need to be aware that the role of training institutions is a service industry which is responsible for satisfying learner needs (Elliott & Shin, 2002). Currently, there have been many researches on students’ satisfaction. However, each research has its own objectives and is conducted on different scales. This study is implemented to provide information about the factors affecting master students’ satisfaction with the training service at VNU School of Interdisciplinary Studies (VNU SIS). Through it, the research offers a number of solutions to improving the satisfaction level of the master students at VNU SIS in the coming time.

Animal Images

A mediolateral gradation in neural responses for images spanning animals to artificial objects is observed in the ventral temporal cortex (VTC). Which information streams drive this organisation is an ongoing debate. Recently, in Proklova et al. (2016), the visual shape and category (“animacy”) dimensions in a set of stimuli were dissociated using a behavioural measure of visual feature information. fMRI responses revealed a neural cluster (extra-visual animacy cluster - xVAC) which encoded category information unexplained by visual feature information, suggesting extra-visual contributions to the organisation in the ventral visual stream. We reassess these findings using Convolutional Neural Networks (CNNs) as models for the ventral visual stream. The visual features developed in the CNN layers can categorise the shape-matched stimuli from Proklova et al. (2016) in contrast to the behavioural measures used in the study. The category organisations in xVAC and VTC are explained to a large degree by the CNN visual feature differences, casting doubt over the suggestion that visual feature differences cannot account for the animacy organisation. To inform the debate further, we designed a set of stimuli with animal images to dissociate the animacy organisation driven by the CNN visual features from the degree of familiarity and agency (thoughtfulness and feelings). Preliminary results from a new fMRI experiment designed to understand the contribution of these non-visual features are presented.

This paper discusses arguments for and against introducing competition into the accounting standard-setting process in the U.S. by allowing individual corporations to issue financial reports prepared in accordance with either FASB or IASB rules. The paper examines several arguments supporting the status quo, including (1) the FASB's experience and world leadership in making accounting rules; (2) the increased risk of a “race to the bottom” under regulatory competition; (3) the inability of most users of financial reports to understand the complex technical issues underlying accounting standards; (4) the possibility that IASB's standards will be diluted to gain international acceptance, allowing additional opportunities for earnings management; (5) the risks of the IASB being deadlocked or captured by interests hostile to business; (6) the costs of experimentation in standard setting; and (7) economies from network externalities. Arguments examined on the other side include how competition will (1) help meet the needs of globalized businesses; (2) increase the likelihood that the accounting standards will be efficient; (3) help protect standard setters from undue pressure from interest groups; (4) allow different standards to develop for different corporate clienteles; (5) allow corporations to send more informative signals by their choice of accounting standards; (6) protect corporations against capture of regulatory body by narrow interests; and (7) not affect network externalities at national or global scales.
