Volunteering: the practice of working on behalf of others without payment for time and services. reviewers of papers, the list of those who serve the Society in some capacity is a long one. In fact, there are over 90 distinct names on the list of committee-members alone, and I would venture that many readers of this column have served as a Society volunteer in some capacity at some point. On behalf of the Society, I thank you for your efforts! And if you haven't yet enjoyed the privilege of serving as an ITSoc volunteer, I would encourage you to seize the opportunity when it arises. — e — Eigenfactor tm : a rating of the (purported) total importance of a scientifi c journal (see www.eigenfactor.org). All bibliometric measures that attempt to boil the infl uence, impact, and " importance " of a scientifi c journal down to a single number should be treated with a healthy degree of skepticism. Nevertheless, members of the Information Theory Society may be interested to know that the IEEE Transactions on Information Theory currently ranks fi rst among all journals in electrical engineering, computer science and applied mathematics in Eigenfactor tm score. Eigenfactor assigns a score to a journal based on the number of times articles from the journal published in the past fi ve years have been cited in the present year, giving higher weight (in a manner similar to Google's PageRank algorithm) to citations arising from journals that are themselves highly cited. Journal self-citations (references from articles in a journal to another article in the same journal) are not counted. Unlike the so-called " Impact Factor, " which measures citations in a given year to articles published in the previous two years only, the Eigenfactor score has a longer window over which " impact " is measured. Nevertheless, with a " cited half-life " of over 9 years (meaning that half of the citations to the Transactions in a given year are to articles that were published more than 9 years before), even a fi ve-year citation window may fail to properly recognize the infl uence of our venerable Transactions. On June 30, Editor-in-Chief of the Transactions, Ezio Biglieri, reached the end of his term. Every paper submitted to the Transactions in the past three years was handled by Ezio—on the order of 2800 during his tenure as EiC. Under Ezio's careful stewardship, …

志愿者：代表他人的习惯，而没有时间和服务的审核，实际上是在某种程度上为社会服务的人。然而，我享受着ITSOC志愿者的特权，我鼓励您在出现的机会时抓住机会 - 健康的持怀疑态度。信息理论社会可能有兴趣知道，有关信息理论的IEEE交易目前在电气工程，计算机科学和eigenfactor tm分数中的数学中排名第一。算法是由高度引用的期刊引起的。年（这意味着在给定年份中对交易的一半是在9年前发表的文章），即使是在6月30日，Ezio Biglieri的命令均在三年中，也可以在6月30日订购。在EIC任职期间。
