Enhancing strategic defensive positioning and performance in the outfield. 加强战略防守定位和外场表现。

Over the past 20 years, professional and collegiate baseball has undergone a transformation, with statistics and analytics increasingly factoring into most of the decisions being made on the field. One particular example of the increased role of analytics is in the positioning of outfielders, who are tasked with tracking down balls hit to the outfield to record outs and minimize potential offensive damage. This paper explores the potential of location analytics to enhance the strategic positioning of players, enabling improved response and performance. We implement a location optimization model to analyze collegiate ball-tracking data, seeking outfielder locations that simultaneously minimize the average distance to a batted ball and maximize the weighted importance of batted ball coverage within a response standard. Trade-off outfielder configurations are compared to observed fielder positioning, finding that location models and spatial optimization can lead to performance improvements ranging from 1 to 3%, offering a significant strategic advantage over the course of a season.

在过去的20年里，职业棒球和大学棒球经历了一场变革，统计和分析越来越多地考虑到球场上做出的大多数决定。分析作用增强的一个特别例子是外野手的定位，他们的任务是追踪打到外野的球，以记录出局并尽量减少潜在的进攻伤害。本文探讨了位置分析的潜力，以增强玩家的战略定位，使改进的反应和性能。我们实现了一个位置优化模型来分析大学的球跟踪数据，寻找外场手的位置，同时最小化到击球的平均距离和最大化击球覆盖在响应标准内的加权重要性。将权衡外野手配置与观察外野手位置进行比较，发现位置模型和空间优化可以导致性能提高1%至3%，在整个赛季中提供显着的战略优势。

The propagation effect of commuting to work in the spatial transmission of COVID-19. COVID-19 空间传播中通勤的传播效应。
IF 2.8 3区 地球科学 Q1 GEOGRAPHY
Journal of Geographical Systems

This work is concerned with the spatiotemporal dynamics of the coronavirus disease 2019 (COVID-19) in Germany. Our goal is twofold: first, we propose a novel spatial econometric model of the epidemic spread across NUTS-3 regions to identify the role played by commuting-to-work patterns for spatial disease transmission. Second, we explore if the imposed containment (lockdown) measures during the first pandemic wave in spring 2020 have affected the strength of this transmission channel. Our results from a spatial panel error correction model indicate that, without containment measures in place, commuting-to-work patterns were the first factor to significantly determine the spatial dynamics of daily COVID-19 cases in Germany. This indicates that job commuting, particularly during the initial phase of a pandemic wave, should be regarded and accordingly monitored as a relevant spatial transmission channel of COVID-19 in a system of economically interconnected regions. Our estimation results also provide evidence for the triggering role of local hot spots in disease transmission and point to the effectiveness of containment measures in mitigating the spread of the virus across German regions through reduced job commuting and other forms of mobility.

这项研究关注德国 2019 年冠状病毒疾病（COVID-19）的时空动态。我们的目标有两个：首先，我们提出了一个新颖的空间计量经济模型，用于分析疫情在 NUTS-3 地区的传播情况，以确定上下班通勤模式在疾病空间传播中所起的作用。其次，我们探讨了 2020 年春季第一波大流行期间实施的遏制（封锁）措施是否影响了这一传播渠道的强度。我们通过空间面板误差修正模型得出的结果表明，在没有采取遏制措施的情况下，上下班通勤模式是显著决定德国 COVID-19 日病例空间动态的首要因素。这表明，在一个经济相互关联的地区系统中，通勤（尤其是在流行病浪潮的初期阶段）应被视为 COVID-19 的一个相关空间传播渠道，并应受到相应的监控。我们的估算结果还为地方热点在疾病传播中的触发作用提供了证据，并表明遏制措施在通过减少工作通勤和其他形式的流动来减轻病毒在德国各地区传播方面的有效性：在线版本包含补充材料，可查阅 10.1007/s10109-021-00349-3。
