Die belang van Lisosiem (Muramidase) hematologiese studies
Markedly increased quantities of lysozyme (muramidase) are found in the serum of cases of monocytic, myelocytic and myelomonocytic leukaemia while reduced levels are found in lymphocytic leukaemia. Increased activity is also found in serum of patients with tuberculosis, pyelonephritis and sarcoidosis. The enzyme apparently is physicochemically identical to the lysozyme of normal tears, leucocytes and serum but structurally different from the lysozyme of hen's egg white. The Iysoplate technique with M.lysodeikticus suspended in buffered agar gel represents a simplified micro-method for assaying human iysozyme. Present evidence indicates that lysozyme is the principal, if not the sole product of proliferating monocytes in monomyelocytic leukaemia and that serial determinations should be a useful routine diagnostic procedure in leukaemia

Instructional Coaches\u27 Perceptions of the Extent to which Varied Professional Learning Experiences Impact their Efficacy
The purpose of this study was to contribute to the limited body of research on the factors that impact the ability of instructional coaches to be highly effective in their multi-faceted roles. Specifically, the study examined the perceptions of instructional coaches regarding the effectiveness of varied professional learning experiences in addressing their own professional development needs and how instructional coaches interpreted their role and function as well as the knowledge and skills they deemed essential in performing their duties.
This mixed- methods study was conducted in the Piedmont area of North Carolina, it involved three data collection instruments: a survey was administered to 26 instructional coaches, 10 interviews and two focus group discussions were also conducted, each focus group had four participants. The conceptual framework underpinning the study was Mezirow’s Transformative Learning Theory and the Literature Review focused on the role of coach, best practices for instructional coaches and the professional development needs of coaches.
All of the coaches reported feeling unprepared for the role, that the first year was a steep learning curve and most learning was on-the-job and/or from other coaches. Other emerging themes included: Coaches had no clear consistent role description, the role was multifaceted with a wide range of diverse responsibilities, role conflict negatively impacted coaching activities, and the majority of activities did not involve direct, individual coaching. Overwhelmingly coaches described themselves as relationship builders and helpers with several coaches expressing the need to improve their coaching skills and their knowledge of adult learning theory
Chapter 3 Federal systems of governance in Africa
Federalism as a mode of governance has been a popular response to most conflicts which stemmed from ethnic/language/religious mobilisation. However, the track record of resolving communal or identity conflicts has not always been good, the least of all in Somalia, Sudan and South Sudan. Why the lack of success? Is the federal solution inherently inappropriate for communal accommodation by exacerbating the problem? If not inevitably or inherently inappropriate, is it then a question of poor design? Or is it merely ineffectual implementation of the ‘federal solution’? The chapter argues that federal arrangements in Africa have been the last measure to hold countries together; therefore federalism per se cannot blamed for persistent conflicts. Whether federalism is able to address communal conflicts depends much on constitutional designs dealing with both ethnic issues and federal concepts in general. Where federal solutions have been tried, it is highly centralised, and even then often superficially and reluctantly implemented. To judge the efficacy of federal arrangements in constitutions they first must be implemented. This depends again on a broader embrace of constitutionalism; democracy, separation of powers, limited government, and the rule of law have to become part of political/legal culture of a country
