title: Reactive Strength as a Metric for Informing Return-to-Sport Decisions: A Case-Control Study

authors: Teichmann, Jorg

subjects: science & technology

abstract: Objective: Current return-to-sport decisions are primarily based on elapsed time since surgery or injury and strength measures. Given data that show rates of successful return to competitive sport at around 55%, there is strong rationale for adopting tools that will better inform return-to-sport decisions. The authors’ objective was to assess reactive strength as a metric for informing return-to-sport decisions. 
Design: Case-control design. 
Methods: Fifteen elite athletes from national sports teams (23 [6.0] y) in the final phase of their return-to-sport protocol following a unilateral knee injury and 16 age-matched control athletes (22 [4.6] y) performed a unilateral isometric strength test and 24-cm drop jump test. Pairwise comparisons were used to determine differences between legs within groups and differences in interleg asymmetry between groups. 
Results: Strength measures did not distinguish the control from the rehabilitation group; however, clear differences in the degree of asymmetry were apparent between the control and rehabilitation groups for contact time (Cohen d = 0.56; −0.14 to 1.27; 8.2%; P = .113), flight time (d = 1.10; 0.44 to 1.76; 16.0%; P = .002), and reactive strength index (d = 1.27; 0.50 to 2.04; 22.4%; P = .002). 
Conclusion: Reactive strength data provide insight into functional deficits that persist into the final phase of a return-to-sport protocol. The authors’ findings support the use of dynamic assessment tools to inform return-to-sport decisions to limit potential for injury.

title: A socio-legal analysis of the conceptions of privacy and information security in relation to the laws of encryption

authors: Dizon, Michael

abstract: Due to the growing collection of users’ personal data by companies, confirmed incidences of mass surveillance by government agencies, and increasing occurrence of large-scale data breaches, people today are rightly concerned about their privacy and the security of their data and the information and communications technologies they use on a daily basis. Faced with these multiplying cyberthreats and risks, ordinary users and citizens have come to rely on both law and technology for protection, particularly encryption as a technical remedy. The problem though is that the law and encryption offer protection in diverse ways. Moreover, people’s understanding of the relevant laws and how they actually safeguard privacy and information security is not sufficiently grounded in the legal and socio-technical contexts. Using New Zealand users, developers and regulators as subjects, this paper will discuss what their varying conceptions or notions of privacy and information security are in relation to encryption and compare these with the applicable laws. This paper will explain why the most pertinent laws are not the oft-cited privacy and data protection laws but are those that concern law enforcement and criminal procedure. This paper argues that the rights of the accused and other rules involving criminal investigations and proceedings are germane to the issue of privacy and security in a digital and connected society.

title: Indigenous psychologies, fourth world peoples and the international literature: Finding ourselves in online abstracting and indexing databases

authors: Nikora, Linda Waimarie

subjects: indigenous psychologies

abstract: The presence and visibility of indigenous people and experience in the field of indigenous psychologies is vital to articulating existence, life, self-determination and future making. This article highlights examples of indigenous Psychology being both absent and present at the same time in OAD (online academic databases).
