The R&D and marketing cooperation across new product development stages: An empirical study of Taiwan's IT industry

This study extends the new product development (NPD) process research to a new environmental context (Taiwan's IT industry) and a new business type (original design manufacturing, ODM). Taiwan's IT industry has achieved a very outstanding performance during the last two decades. The island's experience is quite valuable for those emerging countries that are struggling to transform themselves from producing low-value goods to making high-technology products. After analyzing the data collected from 153 research and development (R&D) and marketing managers in Taiwanese IT firms, this study finds that the higher the perceived importance of R&D-marketing cooperation is, the higher the attained level of R&D-marketing cooperation will be. Consequently, a better NPD performance can be achieved. This study additionally reports that a firm that has adopted a Defender innovation strategy attains a lower level of R&D-marketing cooperation, and has a poorer NPD performance than those firms that adopted either Prospector or Analyzer innovation strategies. Finally, environmental uncertainty has no significant impacts on the perceived importance and the attained level of R&D-marketing cooperation.

Critical aggressive acceleration values and models for fuel consumption when starting and driving a passenger car running on LPG

The models based on vehicle speed have been used to estimate fuel consumption and CO₂ emissions. However, these models could not properly estimate the change in fuel consumption and CO₂ emissions as the speed changes. As for the alternative method, people try to consider using acceleration instead of speed. Although acceleration has been seriously considered, determining critical aggressive acceleration value in relation to fuel consumption and CO₂ emissions is difficult to find. In this study, evaluation models of fuel consumption were developed using instantaneous acceleration, and we defined the critical aggressive acceleration values for different states of the vehicle from the viewpoints of fuel consumption and emissions. We used a mid-sized Liquefied Petroleum Gas (LPG) passenger car and obtained instantaneous data from a digital tachograph installed in the car while it accelerates. We developed two fuel consumption models and found critical aggressive accelerations, respectively: a model of starting vehicle that measures range of speed required to overcome the inertia during acceleration from stop state, and the other model for the driving state. We used Classification and Regression Tree (CART) analysis to find the critical aggressive accelerations at which the increments of fuel consumption change abruptly. As a result, the critical aggressive accelerations causing abrupt change in the increments of fuel consumption were found to be 2.598 m/s² for the starting of vehicles and 1.4705 m/s² when driving them. We also found that the increments of fuel consumption can be explained through quadratic and exponential functions with instantaneous acceleration.     

基于改进SSD-MobileNet算法的AGV动态目标检测方法

为了提升自动导引运输车(automated guided vehicle,AGV)动态障碍物视觉检测的精度和帧率,提出了一种基于单镜头多盒检测器（single shot multibox detector,SSD）的改进算法。将轻量级MobileNet网络引入到SSD网络结构中,然后利用K-means算法对训练数据集中真实框的AR值进行聚类并更新,最后利用Jeston Nano嵌入式平台搭建了AGV实验系统,引入TensorRT加速引擎,分别对改进前后的SSD-MobileNet模型进行加速优化,并对比分析。结果表明：改进的SSD-MobileNet模型在AGV上使用TensorRT加速引擎的mAP值为79.1%,相比优化前提升了10.8%,对精度影响很小,而帧率达到了25 f/s,较原SSD模型提升了近4倍,且改进后模型规模也比优化前缩小了37%。采用改进算法能够使AGV在运输过程中完成动态障碍物检测任务,可代替人工实现货物高效运输,并节省运输成本,为智能化运输提供了一种新的思路。     

The performance impact of post-M&A interdepartmental integration: An empirical analysis

This study investigates how post-M&A interdepartmental integration affects the efficiency and effectiveness of new product development (NPD).The total sample size was 251 respondents. Confirmatory factor analysis (CFA) and structural equation modeling (SEM) were used for statistical analysis. Analytical results indicate that, although collaboration interdepartmental integration positively correlates with product vision, interaction interdepartmental interaction integration does not reach a significant level. Despite the fact that some interaction is essential when developing new product competitive advantage (NPCA), such interaction does not necessarily achieve success. Further, product vision positively correlates with new product competitive advantage and NPD performance, and new product competitive advantage positively correlates with NPD performance. In addition, an examination of the mediation effect in terms of Sobel t-test reveals that product vision is a significant mediator for the influence of interdepartmental integration on new product competitive advantage, while the new product competitive advantage is also a significant mediator for the influence of interdepartmental integration on NPD performance. Moreover, this study provides a framework for managing post-M&A integration and closes with a discussion of the theoretical and practical implications of the research findings.

经济发展、老龄化与政府债务累积的加速效应

本文基于世界63个经济体1996—2016年的面板数据,运用静态、动态门槛回归模型研究了老龄化对政府债务规模的加速效应。研究表明,从长期来看,老龄化不仅能对政府债务产生显著的正向冲击,而且对于相对发达的经济体而言,老龄化对政府债务累积的影响更大。文章政策含义是,为了减缓加速效应,一方面我们需要通过提高全要素生产率、优化税收结构、完善国有资本划转等方式保持政府收入稳健增长,另一方面需要打破养老支出刚性,使其增长幅度与经济增速和政府收入增速相匹配。     

Earnings acceleration and stock returns

We document that earnings acceleration, defined as the quarter-over-quarter change in earnings growth, has significant explanatory power for future excess returns. These excess returns are robust to a wide range of previously documented anomalies and a battery of risk controls. The future return predictability appears to be consistent with investors assuming a seasonal random walk model for quarterly earnings and missing predictable implications of earnings acceleration for future earnings growth. Finally, the excess returns from the basic earnings acceleration strategy can be enhanced further by focusing on profit firms, low earnings volatility firms and on specific patterns of earnings acceleration.
