the last decade has ushered in a rapidly expanding global discussion regarding acellular dermal matrix (adm) applications, economic analyses, technical considerations, benefits, and risks, with recent emphasis on adm use in breast surgery. this study aims to evaluate global trends in adm research using bibliometric analysis. the top nine plastic surgery journals were determined by impact factor...

Trend growth in total factor productivity (TFP) is unobserved; it evolves continually over time. That assumption is inherent in the use of the Hodrick-Prescott or other bandpass filters to extract trends. Similarly, the Kalman filter/unobserved-components approach assumes that changes in the trend growth rate are normally distributed. In fact, some changes to the trend growth rate of total fact...

Using data for the period 2000 to 2019, aim of this paper is profile and compare research publications in regions continents. The empirical evidence based on Poisson regression model, quantile counts panel negative binomial regression. findings can be summarised as follows: continuous linear increasing trends production knowledge are noted developing specifically Africa even if contribution con...

Although Ethiopia is endowed with diverse agro-ecologies suitable for cereal production, the success of production relies more on climate condition. Therefore, this study initiated to analyze trends of; crops area and productivity in Ethiopia. Data meher season (qt/ha) (ha) were collected from Central statistical Agency (CSA) Trend test was carried out using non-parametric Mann-Kendall’s ...

Introduction The study of tree rings is one of the most widely used methods of climate reconstruction for centuries and millennia, but the occurrence of climatic anomalies such as global warming in recent decades has caused divergence problem in the series of tree rings in some areas. Which challenges the ability of this proxy to regenerate the climate. The “divergence problem” is the differen...

Based on the analysis of knowledge work’s structural characteristics, a relationship model between the knowledge work productivity and the corresponding procedure & standard was established. From the empirical research, this paper pointed that, the process of structuring for knowledge work does not necessarily lead to optimal productivity. The productivity shows a downward trend after the first...
