A/HRC/4/102 page 7 support of national prison systems within United Nations peacekeeping operations. The United Nations Primer for Justice Component in Multidimensional Peace Operations: Strengthening the Rule of Law provides guidance for justice sector field officers. The Office of Legal Affairs, the Department of Peacekeeping Operations, OHCHR, UNODC and UNDP are presently collaborating in the development of a United Nations rule of law index. B. Juvenile justice training materials 14. UNICEF is the principal source of publications relating to juvenile justice and has issued a number of materials, including compilations of good practices, global indicators on juvenile justice, and documentation on children and transitional justice. Many of these materials are applicable in the context of long-term development, but can also be used in post-conflict situations. UNICEF, when appropriate, also develops training materials in local languages. For example, in Tajikistan, a compilation of United Nations standards on juvenile justice was published in Tajik in 2004. In 2005, a special issue of the Children of Tajikistan Bulletin was devoted to juvenile justice. And in 2006, a manual on “Adolescents and the Law” was published for use in the police academy, training modules on the United Nations Minimum Standards on Juvenile Justice were published for use in training judges, and a manual for pilot projects on juvenile justice alternatives was developed. 15. UNODC and UNICEF are jointly publishing a manual for the measurement of juvenile justice indicators and are collaborating on materials to promote the use of United Nations guidelines and materials on matters of justice involving child victims and witnesses. OHCHR Manual on Human Rights for Judges, Prosecutors and Lawyers contains a chapter on “The rights of the child in the administration of justice”, which sets out the normative human rights framework and addresses key questions from a human rights perspective. III. EXAMPLES OF PRACTICAL MEASURES TO ASSIST COUNTRIES IN STRENGTHENING THEIR SYSTEMS OF ADMINISTRATION OF JUSTICE A. Training, workshops and seminars 16. Training, workshops and seminars are core activities of OHCHR and its field presences to strengthen systems of administration of justice. The objective of these efforts is to transmit knowledge concerning human rights standards, jurisprudence, declarations, principles, guidelines and rules. Major themes of training, workshops and seminars include arrest and pretrial detention, conditions of detention, torture, fair trial, and the independence of the judiciary. Where relevant (e.g.: Afghanistan, Colombia, Iraq, Nepal), training is also provided on international humanitarian law. 17. Field presences in Afghanistan, Angola, Azerbaijan, Burundi, Cameroon, Colombia, Democratic Republic of the Congo, Ethiopia, Guatemala, Lebanon, Nepal, Palestine, South Africa, and Tajikistan have, for example, organized training exercises, workshops and seminars relating to the administration of justice in the period 2004-2006. Although not an exhaustive account, some examples from these countries provide an idea of the types of trainings, workshops and seminars that have been organized by OHCHR field presences.
