We are meeting on Microsoft Teams: Forensic analysis in Windows,Android, and iOS operating systems

Microsoft released a new communication platform, Microsoft Teams, in 2017. Due in part to COVID-19, the popularity of communication platforms, like Microsoft Teams, increased exponentially. Given its user base and increased popularity, it seems likely that digital forensic investigators will encounter cases where Microsoft Teams is a relevant component. However, because Microsoft Teams is a relatively new application, there is limited forensic research on the application particularly focusing on mobile operating systems. To address this gap, an analysis of data stored at rest by Microsoft Teams was conducted on the Windows 10 operating system as well as on Android and Apple iOS mobile operating systems. Basic functionalities, such as messaging, sharing files, participating in video conferences, and other functionalities that Teams provides, were performed in an isolated testing environment. Cellebrite UFED Physical Analyzer and Magnet AXIOM Examine tools were used to analyze the mobile devices and the Windows device, respectively. Manual or non-automated investigation recovered, at least partially, the majority of artifacts across all three operating systems. In this study, a total of 77.6% of the populated artifacts were partially or fully recovered in the manual investigation. On the other hand, forensic tools used did not automatically recover many of the artifacts found with the manual investigation. Only 13.8% of artifacts were partially or fully recovered by the forensic tools across all three devices. These discovered artifacts and the results of the investigations are presented in order to aid digital forensic investigations.     

Commentary on Interdisciplinary Teamwork in Family Law Practice

This commentary discusses and expands upon Mosten and Traumm's extraordinary work on interdisciplinary teams. Focusing on the continuum between independence and interdependence in team formation, we explore the benefits of team members' shared responsibility and highlight potential challenges. We emphasize that regardless of where a team may fall on the continuum, establishing and adhering to a strong structure results in increased practitioner satisfaction and better client outcomes. This commentary identifies five best practices that promote highly functioning teams and urges family law practitioners to seek more advanced interdisciplinary team training opportunities.     

基于智能终端的网络社交媒体对公安队伍建设与管理的影响研究

基于智能终端的网络社交媒体具有传播的广泛性和即时性、传播主体的个性化和多元化、传播形式的多样性和丰富性等特点。公安机关在基于智能终端的网络社交媒体传播中的表现形态丰富,呈现出以微博为载体的"平安"系列政务微博、以抖音为载体的系列政务视频、以企业微信为载体的系列政务微信、以微信公众号为载体的系列政务微信和民警个人微信,体现了发布内容的权威性与时效性、发布形式的多样化与生动性、发布场景的生活化与日常化、信息接受对象的明确性与广泛性等特点。基于智能终端的网络社交媒体运用对公安队伍建设与管理的启发主要体现为:提高科学站位,明确互联网思维在公安队伍建设中的定位;加大公安机关在网络社交媒体上的宣传力度,丰富公安工作宣传的类型与内容;加强涉警舆情的处置,提高防范风险意识;充分利用网络社交媒体,开展公安队伍内部建设等。     

CIT in context: the impact of mental health resource availability and district saturation on call dispositions

The goals of Crisis Intervention Team (CIT) programs include improving safety during encounters between police and persons with mental illnesses, diverting persons with mental illnesses away from the criminal justice system, and increasing referral and access to mental health services. CIT is a systemic intervention, and as such, its implementation and effectiveness are influenced by existing practices and infrastructures. However, little research has considered the context in which CIT programs are implemented. In this paper, we present research on CIT in four Chicago police districts that vary in terms of two contextual factors hypothesized to influence the impact of CIT training on how calls involving persons with mental illnesses are resolved. Using data from 112 patrol officers in four Chicago police districts, we consider the impact of mental health services availability and CIT saturation (the percentage of district personnel that are CIT certified). Findings indicate that CIT training increased direction to mental health services primarily in districts with greater availability of mental health services. In districts with low service availability, higher CIT saturation increased direction to mental services. The opposite pattern emerged for contact only or informal call resolution. No effects were found for arrest as a call outcome.     

公共组织转型的现状与未来

以"个体性"和"实体性"为特征的官僚制组织是具有生命周期的,即周期性地陷入僵化的困境并通过组织变革而重新焕发生命.但是,深陷"个体"枷锁中的官僚制在变革上是非常困难的,这就决定了官僚组织的历史性.当前的中国,正处于工业社会向后工业社会的转型,日益增长的复杂性和不确定性,促使了转型中的现代组织是围绕着"团队基础"而不是"个体基础"来构建,高效公共组织必须以公共组织高效团队为根基,而基于团队的公共组织形态--"团队基础公共组织"是开放性的、被社会所结构化的组织形式,也必将成为未来公共组织的发展方向.
