The pursuit of justice increasingly relies on productive interactions between witnesses and investigators from diverse cultural backgrounds during investigative interviews. To date, the role of cultural context has largely been ignored by researchers in the field of investigative interviewing, despite repeated requests from practitioners and policymakers for evidence‐based guidance for the conduct of interviews with people from different cultures. Through examining cultural differences in human memory and communication and considering specific contextual challenges for investigative interviewing through the lens of culture, this review and associated commentaries highlight the scope for considering culture and human diversity in research on, and the practice of, investigative interviewing with victims, witnesses, and other sources. Across 11 commentaries, contributors highlight the importance of considering the role of culture in different investigative interviewing practices (e.g., rapport building, questioning techniques) and contexts (e.g., gender‐based violence, asylum seeking, child abuse), address common areas of cultural mismatch between interviewer–interviewee expectations, and identify critical future routes for research. We call for an increased focus in the investigative interviewing literature on the nature and needs of our global community and encourage constructive and collaborative discussion between researchers and practitioners from around the world to better identify specific challenges and work together towards evidence‐based solutions.

IntroductionWe previously demonstrated that synovial sublining macrophages express folate receptor beta (FRβ). The aim of this study was to evaluate the efficacy of intra-articular administration of a recombinant immunotoxin to FRβ for treating rat antigen-induced arthritis.MethodsA monoclonal antibody (mAb) to rat FRβ was produced by immunizing mice with B300-19 cells (murine pre-B cells) transfected with the rat FRβ gene. Recombinant immunotoxin was prepared by conjugating the Fv portion of the anti-rat FRβ mAb heavy chain with a truncated Pseudomonas exotoxin A and the Fv portion of the anti-rat FRβ mAb light chain. Antigen-induced arthritis was induced through intra-articular injection of methylated bovine serum albumin (mBSA) after two subcutaneous injections of mBSA and complete Freund's adjuvant. Immunotoxin was intra-articularly injected into the arthritis joint every other day for seven days after arthritis onset. Joint swelling was measured and histological scores of inflammation, synovial thickness, cartilage, and bone destruction were determined. Immunohistochemistry was performed to detect osteoclast and osteoclast precursor FRβ-expressing macrophages and cathepsin K-positive cells on day 21.ResultsIntra-articular administration of the immunotoxin attenuated joint swelling (61% suppression; P < 0.01 compared to the control on day 21) and improved histological findings, particularly cartilage and bone destruction (scores of rats treated with control versus the immunotoxin: 2.2 versus 0.5; P < 0.01), by reducing the number of FRβ-expressing macrophages and cathepsin K-positive cells.ConclusionsIntra-articular administration of an immunotoxin to FRβ is effective for improving rat antigen-induced arthritis.

This chapter provides the first comprehensive overview of Japanese youth justice, locating it within wider conceptual considerations of youth justice, such as welfare versus justice and penal populism, before outlining its historical development and questioning its uniqueness. It discusses the contested notion pre-delinquency and its net widening potential and its place in the wider trends in Japanese youth crime. The study critically assesses the overall organization, administration, and impact of the Family Court (equivalent to youth or juvenile courts) and summarizes recent developments in youth crime policy. Although the Family Court is at the center of youth justice, it involves many social welfare elements. Despite the increasingly punitive rhetoric, policy, and legislation for juveniles in Japan, there is no evidence that more juvenile offenders are being committed to the adult courts. Overall, we found a clear precedence of social welfare over criminal policy considerations.
