The Comparative Productivity Efficiency of Taiwan's Integrated Circuits Packaging/Testing Firms

INFOR Information Systems and Operational Research (2008)

Shiu‐Wan Hung Wen‐Min Lu

This paper reconciles diverse efficiency measures to characterize the productivity efficiency of Taiwan's integrated circuits (IC) packaging/testing firms. Productivity efficiency ratings should be considered as a key element for achieving greater business performance and a better market position. This study applies the Data Envelopment Analysis (DEA) approach with the classical radial measure, non-radial efficiency measure and efficiency achievement measure, respectively, combining multiple outputs and inputs to measure the magnitude of performance differences between the IC firms. The empirical result reveals that the overall technical inefficiencies of the firms are primarily due to pure technical inefficiencies rather than scale inefficiencies. A scale problem really does exist in these IC packaging/testing firms, which can be treated as support for future mergers and acquisitions between the firms. The operating efficiency of the IC packaging/testing firms is negatively related to the market-entry time of these firms. In addition, the empirical results in this study indicate that the non-radial efficiency model and the efficiency achievement model can provide more discriminate efficiency measures for the IC firms, while the traditional radial efficiency model can rank the firms by their scale efficiencies as well as analyze the scale profits of the firms.

[The Local Alternative Ti-6Al-4V Alloy Coating of Surgery Steel Instruments for Laser Deposition Forming].

PubMed (2020)

Ying Xu Jian Wu Feng Xiao Xiaofeng Gu Wen‐Min Lu

Aiming at the medical practice problems of the surgical steel medical instruments, such as the crevice corrosion, the poor mechanical compatibility and the Ni, Cr plasma exudation, the laser deposition of Ti-6Al-4V alloy cladding layer at the local functional area as alternative coating was proposed and realized as a new process method. The accurate element content and good formability Ti-6Al-4V cladding powder was chosen, the low power and high duty cycle optimized laser process was adopt, the alternative coating of good fusion and low dilution was prepared. Through the elemental line scanning, the interface microstructure analysis and the experiments of basic mechanical properties, the basic properties of the cladding were characterized and verified. The experiments results showed that, the Ti, Al and V contents of the top coating were respectively about 88%, 4.9% and 3.9%, no sensitizing ions such as Cr and Ni were detected. Initial equiaxed α phase, flake β phase dist were distributed in the coating and interface, the α' martensite was precipitated at the boundary of the flake β phase, some refined granular β phase dispersion pinned to the grain boundary of basket structure. The microhardness of cladding layer was 352.08~312.76 HV0.1. The friction coefficient of the cladding layer was about 0.22~0.65. A new technology and method reference for improving and upgrading the performance of surgical medical devices is provided by this research.

What do U.S. biopharmaceutical companies get from patents and research and development spikes for their dynamic corporate performance?

Managerial and Decision Economics (2020)

Wei‐Kang Wang Wen‐Min Lu Qian Long Kweh Hoang Tu Nhi Truong

This paper investigates how patents and research and development (R&D) spikes affect the corporate performance of 863 firm‐year observations of U.S. biopharmaceutical companies. First, a dynamic data envelopment analysis model is adopted to evaluate the performance of the U.S. biopharmaceutical companies. Then, ordinary least squares regression is used to explore the effects of three patent‐related variables (patent counts, citations, and claims) and R&D spikes on corporate performance. This study finds positive impacts of patent counts, citations, and claims on corporate performance. In addition, the results show that R&D spikes have negative contemporaneous effects and time‐lagged effects on corporate performance.

Business groups' dynamic performance of Taiwan semiconductor industry: the carry-over perspective

Portland International Conference on Management of Engineering and Technology (2013)

Shiu‐Wan Hung Dong‐Sing He Wen‐Min Lu Min-Jhih Cheng

This study evaluates dynamic operating performance for Taiwan's semiconductor industry from 2006 to 2009 by using dynamic DEA, a technique based on the perspective of inter-period carry-over in accounting. Furthermore, the industry' various characteristics are evaluated to determine their relationships to the semiconductor industry's efficiency. The following empirical results are found: companies within a business group are more efficient on average than ones under a non-business group; while IC design companies are more efficient than others, investment firms in China are more competitive; companies with high level scopes generally operate better than those with low level scopes. The potential applications and strengths of using DEA to assess the semiconductor industry are also highlighted.

Nanomedicine-mediated prevention of inflammatory monocytes infiltration ameliorate ovalbumin-induced allergic rhinitis in mouse model

Autoimmunity (2020)

Xiaofeng Gu Feng Xiao Wen‐Min Lu Ying Xu Xia Li

Th2 immune cells infiltration into nasal mucosa is one of the characters of allergic rhinitis (AR). We aimed to explore whether inhibition of Th2 immune cells infiltration would attenuate AR progression. AR mouse model was established by i.p. injection of ovalbumin (OVA). The infiltrated immune cells into nasal lavage fluid were detected by flow cytometry. Cytokine concentration in serum was determined by ELISA. AR mice symptoms were indicated by the number of sneezing and nasal rubbing events. In AR mice, CCL2 expression levels and CD45+CD11b+Ly6Chi inflammatory monocytes cells significantly increased as compared with control mice. CCL2 siRNA encapsulated nanoparticles (NPsiCCL2) prevent CCL2 expression and inflammatory monocytes infiltration in AR mice. NPsiCCL2 treatment dramatically decreased the number of sneezing and nasal rubbing events in AR mice. Moreover, NPsiCCL2 treatment attenuated serum OVA-specific IgE, OVA-specific IgG1 and histamine levels. Mechanically, NPsiCCL2 treatment attenuates AR symptoms via inhibiting Th2 cytokine (IL-4, IL-5 and IL-13) production. Nanomedicine-mediated prevention of inflammatory monocytes infiltration ameliorates ovalbumin-induced allergic rhinitis in mouse model.

Evaluating the resource management and profitability efficiencies of US commercial banks from a dynamic network perspective

Financial Innovation (2024)

Qian Long Kweh Wen‐Min Lu Kaoru Tone Hsian-Ming Liu

Abstract The central concept of strategic benchmarking is resource management efficiency, which ultimately results in profitability. However, little is known about performance measurement from resource-based perspectives. This study uses the data envelopment analysis (DEA) model with a dynamic network structure to measure the resource management and profitability efficiencies of 287 US commercial banks from 2010 to 2020. Furthermore, we provide frontier projections and incorporate five variables, namely capital adequacy, asset quality, management quality, earning ability, and liquidity (i.e., the CAMEL ratings). The results revealed that the room for improvement in bank performance is 55.4%. In addition, we found that the CAMEL ratings of efficient banks are generally higher than those of inefficient banks, and management quality, earnings quality, and liquidity ratios positively contribute to bank performance. Moreover, big banks are generally more efficient than small banks. Overall, this study continues the current heated debate on performance measurement in the banking industry, with a particular focus on the DEA application to answer the fundamental question of why resource management efficiency reflects benchmark firms and provides insights into how efficient management of CAMEL ratings would help in improving their performance.
