Protest participation propensity cues and selective recruitment: Dyadic evidence on rational prospecting.

Who takes to the streets to protest matters. Protest sends signals to decision-makers and biased participation leads to biased signals. This paper examines one driver of biased participation, namely protest recruiters behaving as rational prospectors by only inviting others who they believe are likely to agree to the participation request.

Comparative assessment of current robotic-assisted systems in primary total knee arthroplasty.

Robotic-assisted total knee arthroplasty (TKA) has proven higher accuracy, fewer alignment outliers, and improved short-term clinical outcomes when compared to conventional TKA. However, evidence of cost-effectiveness and individual superiority of one system over another is the subject of further research. Despite its growing adoption rate, published results are still limited and comparative studies are scarce.

Quality of life after staged revision for infected total hip arthroplasty: a systematic review.

Introduction: The aim of this review was to assess (health-related) quality of life ([HR]Qol) after 1-stage or 2-stage revision for prosthetic joint infection of the hip (PJI). Additionally, we compared (HR)QoL scores with normative population scores to assess whether QoL is reduced after revision for PJI.

Methods: A systematic search was performed in Embase, Cochrane and Pubmed.

The missing link in the diffusion of protest: asking others.

Mobilization for protest is a process of diffusion in interpersonal networks. Extant work has found that being asked by people one knows is a key determinant of participation, but the flip side--asking others--has been neglected. The authors examine which prospective participants are most likely to ask others to participate and whom they ask.

High incidence of intraoperative anchorage failure in FasT-fix all inside meniscal suturing device.

The aim of this study was to assess the incidence of intraoperative failure of the FasT-fix (Smith & Nephew, Andover, USA) device for all-inside meniscal repair and to investigate any underlying factors. Searching retrospectively the hospital databases and patient files, we collected 78 cases, totalling 61 successes and 17 failures. Of a total of 190 FasT-fix anchors, 22 failed (a calculated incidence of 11.
