Given advances that streamline breast reconstruction (e.g., prepectoral placement, acellular dermal matrix ADM, oncoplastic surgery), there is concern that nonplastic surgeons are performing a ...growing proportion of breast reconstructive procedures. The purpose of this study was to evaluate US trends in the market share of breast reconstruction performed by plastic compared to general surgeons.
IBM® MarketScan® Commercial Claims 2006-2017 and NSQIP 2005-2020 were queried to identify women who underwent mastectomy with alloplastic (tissue expander or implant-based) or free flap reconstruction, or lumpectomy with oncoplastic reconstruction (breast reduction, mastopexy, or local/regional flap). MarketScan included immediate and delayed reconstructions, while all NSQIP reconstructions were immediate. Poisson regression with incident rate ratios (IRRs) modeled trends in surgeon type over time.
The cohort included 65 168 encounters from MarketScan and 73 351 from NSQIP. Plastic surgeons performed 95.8% of free flap, 93.8% of alloplastic, and 64.9% of oncoplastic reconstructions. Plastic surgeons performed an increasing proportion of immediate oncoplastic reduction and mastopexy (MarketScan IRR: 1.077, 95% confidence interval CI: 1.060-1.094, p < 0.001; NSQIP IRR: 1.041, 95% CI: 1.030-1.052, p < 0.001). There were no clinically significant trends for delayed oncoplastic, alloplastic, or free flap reconstructions. Plastic surgeons were more likely to use ADM compared to general surgeons in NSQIP (p < 0.001).
Plastic surgeons gained market share in immediate oncoplastic breast reduction and mastopexy over the past two decades without any loss in alloplastic or free flap breast reconstruction. Plastic surgeons should continue collaboration with breast surgical oncologists to reinforce the shared surgeon model for management of breast cancer.

This paper deals with the topic of market analysis of drones (or UAVs) for civil use. This is an analytical overview study. In the introduction, we offer an overview of the main historical milestones ...on the topic of drones. We then provide a classification and explanation of the main types of drones. The main part of the article contains structured information about the drone market, its status in terms of market shares and relative market shares. For a structured view of this market, we used the BCG method: we calculated the market growth and relative market shares. This market is dynamic and growing gradually. Established brands forming a strong competitive environment. In the photo-video segment, the Chinese brand DJI has a strong and dominant position. Demand on the consumer side is also growing, as is the reputation of the most used product brands.
► Strategic management of inter-organizational relationships is essential for firms. ► We study the different effects of social capital dimensions on international market share. ► Our study ...specifically tests a three-path mediation model. ► Relational and resource dimensions fully mediate the effect of structural dimension on international social capital. ► The resource dimension represents the best predictor of the international market share.
Our paper contributes to the growing research by examining the interrelations between the dimensions of capital and their effects on the international market share of multinational companies in the global contractors industry. Previous works on social capital have failed to study the interrelationships between its dimensions or have proposed models with direct relationships. The current study proposes a multiple mediating model and tests the mediation. In particular, we posit that the relational and resource dimensions play a mediating role in the structural dimension-international market share relationship. A variance-based structural equation modeling (Partial Least Squares) has been applied to a sample made up of 225 global contractors. Our analysis lends support to the importance of the central positions of a firm and their influence on international market share. Moreover, mediation hypotheses posit how the relational and resource dimensions play a critical mediating role in the structural dimension – international market share relationship. Analysis of the data suggest that the dimensions of social capital are interrelated in such a way that the relational and resource dimensions: (a) fully mediate the effect of centrality (structural dimension) on the international share market and (b) exert significant influence on the international market share of each company.
Hydrogen fuel cell vehicles (HFCVs) represent an eco-friendly means of transportation, acknowledged for their potential to curtail gasoline consumption, mitigating greenhouse gas emissions and air ...pollution. The conjoint analysis approach is employed in this paper to comprehend consumers preferences for HFCVs across multiple Chinese cities. Through an online survey questionnaire, car usage and transport policy attributes are identified as crucial factors to establish choice preference models. Results indicate the pivotal role of purchase price and cruising range as the most influential attributes shaping consumer preferences for HFCVs, with rankings varying by geographical location. Market share insights and simulation analysis confirms the significance of attributes and describes the impact of cross-changes on HFCV choice behaviors. These findings offer crucial insights for automakers and policymakers, outlining priorities and optimal policy combination when introducing HFCVs in multiple Chinese cities.
•Conjoint analysis was employed to unveil pivotal attributes in Chinese market.•Purchase price and cruising range of HFVCs dominate consumer choices.•HFCV attribute significance varies across Beijing, Shanghai, Guangdong, and others.•Optimal HFCV policies encompass financial subsidies, low fuel cost, and expanded refueling infrastructure.•Provide valuable insights for automakers and policymakers navigating the diverse Chinese market.
We study lender behavior in the peer-to-peer (P2P) lending market, where individuals bid on unsecured microloans requested by other individual borrowers. Online P2P exchanges are growing, but lenders ...in this market are not professional investors. In addition, lenders have to take big risks because loans in P2P lending are granted without collateral. While the P2P lending market shares some characteristics of online markets with respect to herding behavior, it also has characteristics that may discourage it. This study empirically investigates herding behavior in the P2P lending market where seemingly conflicting conditions and features of herding are present. Using a large sample of daily data from one of the largest P2P lending platforms in Korea, we find strong evidence of herding and its diminishing marginal effect as bidding advances. We employ a multinomial logit market-share model in which relevant variables from prior studies on P2P lending are assessed.
El agronegocio brasileño se ha destacado en la comercialización internacional de commodities, el complejo sojero, que, desde la década de 2000, asumió el papel protagónico en la agenda exportadora ...nacional. Por lo tanto, este artículo analiza los determinantes del comercio internacional inherentes al complejo sojero brasileño abarcando el período 2000 a 2019. Para ello, se utilizó el modelo Constant Market Share (CMS), considerando cuatro subperíodos: 2000-2004, 2005-2011, 2012. -2015 y 20162019. Los datos utilizados para llevar a cabo este estudio fueron recopilados de la Base de datos estadísticos del comercio de productos básicos de las Naciones Unidas (UN Trade). Como resultado obtenido por la CMS, se destaca que: el efecto crecimiento del comercio mundial y el efecto competitividad fueron responsables del aumento de las exportaciones de soja, mientras que el crecimiento de las exportaciones de aceite de soja se explicó por el crecimiento de las exportaciones mundiales, en el primer y último subperíodo, por el efecto competitividad, en el segundo subperíodo, y, por la distribución de mercados en el tercer subperíodo. El crecimiento de las exportaciones nacionales de harina de soja se evidenció, en la mayoría de los subperíodos, debido al crecimiento de las exportaciones mundiales, excepto en el segundo subperíodo en el que predominó el efecto competitividad. Además, se encontró que el crecimiento de las exportaciones mundiales fue el responsable de impulsar el complejo sojero de forma agregada en todos los subperíodos.
Brazilian agribusiness has stood out in the international trade of commodities, particularly the soy complex, which, since the 2000s, has assumed the leading role in the national export agenda. Therefore, this article aims to analyze the determinants of international trade inherent to the Brazilian soy complex covering the period from 2000 to 2019. For this purpose, the Constant Market Share (CMS) model was used, considering four subperiods: 2000-2019. 2004, 2005-2011, 2012-2015 and 2016-2019. The data used to carry out this study were collected from the United Nations Commodity Trade Statistics Database (UN Comtrade). As a result, obtained by the CMS, it is highlighted that the growth effect of world trade and the competitiveness effect was responsible for the increase in exports of soy in grain since the growth of exports of soy oil was explained by the development of world exports, in the first and last subperiod, by the competitiveness effect, in the second subperiod, and by the distribution of markets in the third subperiod. The growth of national soybean meal exports was evident for most subperiods due to the development of world exports, except in the second subperiod in which the competitiveness effect was predominant. Furthermore, it was found that the growth of world exports was responsible for promoting the soy complex in aggregate form in all subperiods
Brand equity is the differential preference and response to marketing effort that a product obtains because of its brand identification. Brand equity can be measured using either consumer perceptions ...or sales. Consumer-based brand equity (CBBE) measures what consumers think and feel about the brand, whereas sales-based brand equity (SBBE) is the brand intercept in a choice or market share model. This article studies the extent to which CBBE manifests itself in SBBE and marketing-mix response using ten years of IRI scanner and Brand Asset Valuator data for 290 brands spanning 25 packaged good categories. The authors uncover a fairly strong positive association of SBBE with three dimensions of CBBE—relevance, esteem, and knowledge—but a slight negative correspondence with the fourth dimension, energized differentiation. They also reveal new insights on the category characteristics that moderate the CBBE-SBBE relationship and document a more nuanced association of the CBBE dimensions with response to the major marketing-mix variables than heretofore assumed. The authors discuss implications for academic researchers who predict and test the impact of brand equity, for market researchers who measure it, and for marketers who want to translate their brand equity into marketplace success.
