  • Welcoming Remarks by Dr Naledi Pandor, Minister of International
    1 WELCOMING REMARKS BY DR NALEDI PANDOR, MINISTER OF INTERNATIONAL RELATIONS AND COOPERATION, DURING VIRTUAL THE PROGRAMME FOR INFRASTRUCTURE DEVELOPME IN AFRICA (PIDA) WEEK 2020: 19 JANUARY 2021 Programme Director; Your Excellencies; Ladies and Gentlemen: Compliments of the new season to you all! I would also like to welcome you to PIDA week 2020. We are brought together today by commitment to our shared vision for a prosperous Africa and a better world. We meet at a time of great distress both for the African continent and the entire world. As PIDA 2020 shows, the Covid-19 global pandemic has at once disrupted and transformed the way we do business and how we interact with one another. Nevertheless, it is necessary to meet to continue determining plans to help us achieve progress and to avoid further decline in our socio-economic conditions. Your Excellencies; The Programme for Infrastructure Development in Africa (PIDA) was created as a framework for stakeholders in the continent to utilise and develop the infrastructure necessary for tangible growth and to integrate the continent physically, economically and socially, with the objective of boosting trade, creating new jobs for Africa’s growing population and improving the overall socio-economic conditions of our people. 2 PIDA was also designed to mobilise resources to transform our infrastructure as well as modernise it in order to integrate the African continent and the world. Achieving these goals can only be done through our collective effort as Member States effectively using our existing frameworks of regional and continental cooperation. A great deal of progress is being recorded in PIDA implementation, and AUDA-NEPAD remains pivotal in this exercise we are not at the required level of implementation and governments and the AU need to give greater support to active implementation.

  • 25 Years in the Global Arena
    25 Years in the Global Arena Working for a Better South Africa, in a Better and Safer Africa, in a Better World South Africa’s achievement of democracy had global significance, enabling the free South Africa to immediately become a global citizen of note. As the free South Africa reaches 25 years since the first democratic elections in 1994, let us reflect on what it has achieved in the global arena. 2 25 Years in the Global Arena “We are aware that by our common actions we have sought not only the liberation of the people of South Africa but also the extension of the frontiers of democracy, non-racial, non-sexism and human solidarity throughout the world.” – Nelson Mandela, Speech to the United Nations, 24 September 1993 Icons such as Nelson Mandela and other freedom fighters, South Africa’s cultural and performing artists and its sportsmen and women combined with the famous democratic transition gave South Africa notable prestige globally. 25 Years in the Global Arena 3 4 25 Years in the Global Arena 25 Years in the Global Arena 5 Madiba Magic – Returning to the global stage 6 25 Years in the Global Arena 25 Years in the Global Arena 7 8 25 Years in the Global Arena International solidarity OR Tambo brought the friends of South Africa together throughout the world in a continuous and sustained mobilisation of the international community in support of a free and democratic South Africa. During his time abroad, he was instrumental in the establishment of African National Congress missions globally – 27 countries in total by 1990.

  • Chronology of Seventh-Day Adventist Education: 1872-1972
    CII818L8tl or SIYIITI·Ill IIYIITIST IIUCITIGI CENTURY OF ADVENTIST EDUCATION 1872 - 1972 ·,; Compiled by Walton J. Brown, Ph.D. Department of Education, General Conference of Seventh-day Adventists ·t. 6840 Eastern Avenue, N.W., Washington, D.C. 20012 i/ .I Foreword In anticipation of the education centennial in 1972 and the publication of a Seventh-day Adventist chronology of education, the General Conference Department of Education started to make inquiries of the world field for historical facts and statistics regarding the various facets of the church program in education. The information started to come in about a year ago. Whlle some of the responses were quite detalled, there were others that were rather general and indefinite. There were gaps and omissions and in several instances conflicting statements on certain events. In view of the limited time and the apparent cessation of incoming materials from the field, a small committee was named with Doctor Walton J. Brown as chairman. It was this committee's responsibility to execute the project in spite of the lack of substantiation of certain information. We believe that this is the first project of its kind in the denomination's history. It is hoped that when the various educators and administrators re­ view the data about their own organizations, they will notify the Department of Education concerning any corrections and additions. They should please include supporting evidence from as many sources as possible. It is hoped that within the next five to ten years a revised edition may replace this first one. It would contain not only necessary changes, but also would be brought up to date.

  • 2020–21 Commencement Program
    Commencement UNIVERSITY OF COLORADO BOULDER MAY 6, 2021 One Hundred Forty-Fifth Year of the University NORLIN CHARGE TO THE GRADUATES The first commencement at the University of Colorado was held for six graduates on June 8, 1882, in the chapel of Old Main. It was not until 40 years later, on September 4, 1922, that the first summer commencement was held. Since the first commencement in 1882, the University of Colorado Boulder has awarded more than 350,000 degrees. The traditional Norlin Charge to the graduates was first read by President George Norlin to the June 1935 graduating class. You are now certified to the world at large as alumni of the university. She is your kindly mother and you her cherished sons and daughters. This exercise denotes not your severance from her, but your union with her. Commencement does not mean, as many wrongly think, the breaking of ties and the beginning of life apart. Rather it marks your initiation in the fullest sense into the fellowship of the university, as bearers of her torch, as centers of her influence, as promoters of her spirit. The university is not the campus, not the buildings on campus, not the faculties, not the students of any one time—not one of these or all of them. The university consists of all who come into and go forth from her halls, who are touched by her influence, and who carry on her spirit. Wherever you go, the university goes with you. Wherever you are at work, there is the university at work.
