基于神经网络的超声医学图像自动分割

图像分割是多维超声医学图像重建中最重要和最困难的问题。文中将传统的最近邻分类方法与自组织神经网络相结合，提出了一种超声医学图像的自动分割方法。实验表明，与传统的Ｋ平均方法相比，该方法除具有自动分割优点外，还具有稳定性好，自适应强，分割准确等优点。

汉英语言差异对汉英翻译、写作的影响(下)

（注：本文（上）见本刊2006年第3期） （七）英语多长句、从句。汉语多短句、分句英语句子里主从关系很多,体现出不同的层次。汉语句子里并列关系居多,孰主孰从不明显。一般来讲,英语多长句、从句,汉语多短句、分句。由于英语是“法治”的语言,只要结构上没有出现错误,许多意思往往可以放在一个长句中表达,往往通过从句引导词与主句或其它从句连接,整个句子尽管表面上看错综复杂却是一个整体。汉语则正好相反,由于是“人治”,语义通过字词直接表达,加上表达结构相对松散,习惯上容易形成多个并列分句,不同的意思往往通过不同的短句或分句表达出来。     

Dimensional Latent Structure of Relationship Quality: Results of Three Representative Population Samples

A fundamental question facing every latent construct (e.g., relationship quality) is whether the construct is categorical or dimensional in nature. The authors analyzed the latent status of relationship quality in 3 large general German population samples using the Partnership Questionnaire (PFB), the Quality of Relationship Inventory, and the short form of the PFB (PFB‐K; N₁ = 1,330, N₂ = 1,494, N₃ = 1,390). They applied 3 widely used taxometric methods: (a) MAXEIG, (b) MAMBAC, and (c) L‐Mode. Simulation data were created to evaluate the comparison curve fit index values, which were below 0.5 across the 3 German population samples, supporting a dimensional solution. Hence, in the current study the latent structure of relationship quality encompassed differences in degree rather than kind. Implications of the dimensional latent status of relationship quality, as well as causes of the discrepant findings with previous taxometric studies, are discussed.     

Decision Making in Cross‐Functional Teams: The Role of Decision Power*

Through a series of game‐theoretical models, this study systematically examines decision making in cross‐functional teams. It provides a framework for the design of an organization‐specific decision‐making process and for the alignment of a team's microdecision with the “optimal” decision that maximizes the firm's payoff. This study finds that even without changing the team leader, firms could change and even dictate the team's microdecision outcome via adjusting the team member's seniority, empowering team members with veto power or involving a supervisor as a threat to overrule the team decision. This finding implies that to reposition products in the marketplace, structuring cross‐functional teams’ microdecision‐making processes is essential.     

A Decisional Framework of Offshoring: Integrating Insights from 25 Years of Research to Provide Direction for Future*

Mirroring the growing trend for firms to support their operations by locating activities abroad, research on the practice of offshoring has increased considerably in recent years. However, despite the mounting research, understanding of the key factors influencing decision‐making for offshoring remains surprisingly limited due to fragmentation. In this study, we synthesize and integrate insights from different research domains in order to develop a comprehensive decisional framework for key offshoring decisions. The integrative decisional framework is based on a systematic review of offshoring research published in the most influential management and business journals in the past 25 years. In addition to providing a snapshot of the state of research on decision‐making for offshoring, this study aims to stimulate future research by identifying promising research opportunities. In particular, we propose that future research should use alternative theories to incorporate overlooked aspects of decision‐making, integrate different theories to account for the interdependencies between decisions, and adopt a portfolio perspective that considers each decision as part of an overall offshoring strategy.
