面向决策的“城市病”诊治情报服务探索

[目的/意义]探究面向决策的“城市病”诊治情报服务模式有利于对“城市病”问题进行综合把脉,帮助城市管理者迅速找准病因、症结,从而提升社会治理效率。[方法/过程]在总结“城市病”诊治相关理论与实践现状的基础上,从宏观环境（信息环境）、中观资源（大数据战略）与用户需求（决策需求）3个层面归纳“城市病”诊治情报服务的推动力,探讨“城市病”诊治情报服务体系的组织架构以及运行机制,指出“城市病”诊治情报服务应是环环相扣、动态演进、递进循环的工程化流程。[结果/结论]情报服务的介入可以促使“城市病”诊治过程更为精细化、系统化与协同化,为政府城市管理与决策提供极为有益的信息决策参考。按照工程化情报服务思维,“城市病”诊治思路将从被动的“应对”向主动的“服务”转变。     

A Publisher Perspective: How One Publisher is Responding to the Changing World of Scholarly Communication

For this talk, Marks was tasked with summarizing the important trends in scholarly publishing in 45 minutes. The speaker reflected on the rapid changes that have occurred in journal publishing, which followed more than 300 years of relatively slow progress. Marks discussed key technology trends such as data curation, Open Access (OA) mandates, and the changes occurring in the global landscape of scholarly communications and library budgets. Wolters Kluwer Health has been responding to these trends with new publishing experiments including a Platinum OA model in emerging markets. Marks discussed the ways that publishers and libraries need to alter their traditional practices and instill a focus on their customers and communities.

Explaining match outcome in elite Australian Rules football using team performance indicators

The relationships between team performance indicators and match outcome have been examined in many team sports, however are limited in Australian Rules football. Using data from the 2013 and 2014 Australian Football League (AFL) regular seasons, this study assessed the ability of commonly reported discrete team performance indicators presented in their relative form (standardised against their opposition for a given match) to explain match outcome (Win/Loss). Logistic regression and decision tree (chi-squared automatic interaction detection (CHAID)) analyses both revealed relative differences between opposing teams for “kicks” and “goal conversion” as the most influential in explaining match outcome, with two models achieving 88.3% and 89.8% classification accuracies, respectively. Models incorporating a smaller performance indicator set displayed a slightly reduced ability to explain match outcome (81.0% and 81.5% for logistic regression and CHAID, respectively). However, both were fit to 2014 data with reduced error in comparison to the full models. Despite performance similarities across the two analysis approaches, the CHAID model revealed multiple winning performance indicator profiles, thereby increasing its comparative feasibility for use in the field. Coaches and analysts may find these results useful in informing strategy and game plan development in Australian Rules football, with the development of team-specific models recommended in future.
