Abstract:

We investigate a durable product retailing and recycling problem in a closed-loop supply chain consisting of a single manufacturer and two competitive retailers, in which the manufacturer collects used products via retailers from the consumers and has sufficient channel power over the retailers to act as a Stackelberg leader; the retailers compete in retail products and recycling used products. In order to analyze the impact of retailing and recycling competitions on the profits of the manufacturer and the competitive retailers, two collection models (coordinated collection (ModelC) and decent

Abstract:

Cognitive radio, which will become a fundamental part of theInternet of Everything(IoE), has been identified as a promising solution for the spectrum scarcity. In a multi-SU and multi-PU cognitive radio network, selecting channels is a fundamental problem due to the channel competition among secondary users (SUs) and packet collision between SUs and primary users (PUs). In this paper, we adopt cooperative sensing method to avoid the packet collision between SUs and PUs and focus on how to collect the spectrum sensing data of SUs for cooperative sensing.

Abstract:

This study aims to investigate the literature in product distribution and channel competition. In this study, past work related to the product distribution through different channels is extensively reviewed. Based on the channel differentiation, channel competition is also reviewed. Finally, the study proposes that the future research may focus on helping the producer make a decision whether to sell the product through its own direct channel (online) through a physical channel or both based on the difference between these two channels.

Abstract:

This paper studies impact of heterogeneous consumer behavior on optimal pricing decisions under dual channel supply chain competition, which consists of one manufacturer and one retailer. The manufacturer is market leader with two sales channels: one is direct channel facing consumers directly and the other is indirect channel facing the retailer. Consumers decide whether to buy and from which channel to buy products. Purchasing decisions are based on considerations of prices posted on different channels, preference or loyalty to specific channels, and degree of rationality in decision-making

We propose a model of retail promotions for competitive distribution channels and investigate whether cooperative advertising programs are profitable for such channels. While previous studies showed that coop programs increase total channel profits in bilateral monopolies, no evidence of such a result has been provided for channels where competition is present at the manufacturing and the retailing levels. In this paper, we consider a distribution channel formed by two manufacturers and two retailers and propose a model that accounts for brand and store substitution effects generated by the re

Abstract:

The authors study business-to-business manufacturers' simultaneous usage of vertically integrated (direct) and third-party (indirect) channels of distribution to serve one geographical market (possibly comprising several market segments) with the same product line. Most theoretical approaches to vertical integration of the distribution function pose the classic question of whether to forward integrate or use independent entities. Having concurrent channels means doing both. This phenomenon is poorly understood, even though it has been growing rapidly. The authors argue that under certain circu

Some suggest that there is a treatment effect of competition on measured productivity, for example, through a reduction of managerial slack. Others argue that greater competition makes unproductive establishments exit by reallocating demand to their productive rivals, raising observed average productivity via selection. I study the ready‐mix concrete industry and offer three perspectives on this ambivalence. First, using a standard decomposition approach, I look for evidence of greater r

Abstract:

Successive earthquakes can drive landscape evolution. However, the mechanism and pace with which landscapes respond remain poorly understood. Offset channels in the Carrizo Plain, California, capture the fluvial response to lateral slip on the San Andreas Fault on millennial time scales. We developed and tested a model that quantifies competition between fault slip, which elongates channels, and aggradation, which causes channel infilling and, ultimately, abandonment. Validation of this model supports a transport-limited fluvial response and implies that measurements derived from present-day c

Abstract:

This study seeks to understand “how” economic shocks drive industry merger activity. We test whether economic shocks from deregulation and technological change drive industry merger activity by increasing industry competition, controlling for the effect of valuations. We find that these shocks drive merger activity through three channels related to industry competition; deregulation drives merger activity by increasing entry and cash flow volatility; technological change drives merger activity by increasing entry and inter-firm dispersion in the quality of production technology. These findings

Globalization brings opportunities and pressures for domestic firms in emerging markets to innovate and improve their competitive position. Using data from 27 emerging market economies, we estimate the effects of foreign competition and linkages with foreign firms on innovation by domestic firms. We provide robust evidence of a positive relationship between foreign competition and innovation, broadly defined. The supply chain of multinational enterprises and trade are also important channels. There is no evidence for an inverted U relationship between innovation and foreign competition. Moreov

This article is devoted to the description of the competitive environment of the educational system of higher education. The directions and forms of competition of Russian universities are revealed in accordance with the constructive theory of competition. The article describes the classical theoretical directions of competition: product, industry, intersectoral, and inter-product competition. Product competition is the competition between manufacturers of interchangeable goods in the same distribution channels. It is a rivalry between competing product brands for distribution, otherwise known

Abstract:

AbstractModels are proposed for channelized and distributed flow of meltwater at the base of an ice sheet. The volumes of both channel and distributed systems evolve according to a competition between processes that open drainage space (e.g. sliding over bedrock, melting of the ice) and processes that close it (e.g. viscous creep of the ice due to a positive effective pressure). Channels are generally predicted to have lower water pressure and therefore capture water from the surrounding regions of distributed flow. There is a natural length scale associated with the distributed system that de

Distribution channels are also substitutable. Using price competition and a game theoretic approach, we find that the same products can be sold at a higher price in the cross-sale channel than in its own centralized distribution channel. The first mover in doing a cross-sale doesnt necessarily enjoy the advantage in terms of higher profit. Not only manufacturers can c

Brain-Computer Interfaces (BCIs) have become a research field with interesting applications, and it can be inferred from published papers that different persons activate different parts of the brain to perform the same action. This paper presents a personalized interface design method, for electroencephalogram- (EEG-) based BCIs, based on channel selection. We describe a novel two-step method in which firstly a computationally inexpensive greedy algorithm finds an adequate search range; and, then, an Estimation of Distribution Algorithm (EDA) is applied in the reduced range to obtain the optim

Abstract:

Manufacturers add online direct channels that inevitably engage in channel competition with offline retail channels. Since price is an important factor in consumers' choice of purchasing channel, pricing strategy has become a popular topic for research on dual-channel competition and coordination. In contrast to previous research on pricing strategies based on the full rationality of members, we focus on the impact of retailers' fairness concerns on pricing strategies. In this study, the hybrid dual-channel supply chain consists of one manufacturer with a direct channel who acts as the leader

Abstract:

Voltage-gated calcium (CaV) channels are associated with β and α2δ auxiliary subunits. This review will concentrate on the function of the α2δ protein family, which has four members. The canonical role for α2δ subunits is to convey a variety of properties on the CaV1 and CaV2 channels, increasing the density of these channels in the plasma membrane and also enhancing their function. More recently, a diverse spectrum of non-canonical interactions for α2δ proteins has been proposed, some of which involve competition with calcium channels for α2δ or increase α2δ trafficking and others which media

Abstract:

Classifying Motor Imaging (MI) Electroencephalogram (EEG) signals is of vital importance for Brain–Computer Interface (BCI) systems, but challenges remain. A key challenge is to reduce the number of channels to improve flexibility, portability, and computational efficiency, especially in multi-class scenarios where more channels are needed for accurate classification. This study demonstrates that combining Electrooculogram (EOG) channels with a reduced set of EEG channels is more effective than relying on a large number of EEG channels alone. EOG channels provide useful information for MI sign

Abstract:

Competition for space between stocked juvenile Atlantic salmon, Salmo salar, and wild juvenile rainbow trout, S. gairdneri, was examined in stream channel experiments, a field experiment, and in field habitat surveys. In stream channels providing riffle and pool habitats, species differed in their distribution both as underyearlings (0+) and as yearlings (1+). Yearling salmon occurred more often in stream channel riffles during trials with 1+ rainbow trout than during trials testing only salmon; trout distributions in the channels were unaffected by salmon.
