and Travis thus systematically and elegantly show that rather than structural convergence, the main contribution of code-switching is in contextual (re)distribution. This study represents a significant milestone in the study of contact-induced change. Methodologically, its use of a purpose-built corpus realizes the promise of modern data collection technologies, and its detailed discussion of the processes of transcription and coding does justice to the analytical nature of these seemingly mundane elements of study design. The application of the variationist comparative method to the question of code-switching and language change is a major advancement in this approach to complex language description. Torres Cacoullos and Travis thus make the case that the hitherto backgrounded analysis of the variable context can serve a more prominent role in the comparative analysis of variable features. Finally, this book’s conclusions indicate that one should not simply assume that code-switching is a catalyst for language change; rather, it must be systematically demonstrated.

因此，Travis 系统而优雅地表明，代码转换的主要贡献不是结构收敛，而是上下文（重新）分布。这项研究代表了接触引起的变化研究中的一个重要里程碑。从方法论上讲，它使用专门构建的语料库实现了现代数据收集技术的前景，它对转录和编码过程的详细讨论恰到好处地反映了研究设计中这些看似平凡的元素的分析性质。变分比较法在语码转换和语言变化问题上的应用是这种复杂语言描述方法的重大进步。Torres Cacoullos 和 Travis 因此证明，迄今为止对变量上下文的背景分析可以在变量特征的比较分析中发挥更突出的作用。最后，本书的结论表明，不应简单地假设代码转换是语言变化的催化剂；相反，它必须被系统地证明。
