This is the ninth annual report on the situation pertaining to language rights and language matters in general in South Africa. It cultivates an awareness of language rights and promotes a culture of taking proactive measures in order to oppose violations of language rights. Such awareness could lead, on the one hand, to the further democratisation of the community, and on the other, to increasing participation in public life.
Asymptotic methods are of great importance for practical applications, especially in dealing with boundary value problems for small stochastic perturbations. This book deals with nonlinear dynamical systems perturbed by noise. It addresses problems in which noise leads to qualitative changes, escape from the attraction domain, or extinction in population dynamics. The most likely exit point and expected escape time are determined with singular perturbation methods for the corresponding Fokker-Planck equation. The authors indicate how their techniques relate to the Itô calculus applied to the Langevin equation. The book will be useful to researchers and graduate students.
The SALRM 2011 provides a rich source of information on a range of language-related subjects. A prominent issue remains the changing of street and place names, including the Pretoria/Tshwane and Louis Trichardt/Makhado sagas. Language in education remains a thorny issue; as medium of instruction at school and tertiary level, and the proposal that passing an African language should be a requirement in order to obtain a tertiary degree in South Africa. In terms of language legislation, the draft version of the National Language Act was proposed. The language of record in courts also received attention in the media.
Johan Smit het ‘n groot bydra gelewer tot die inhoud van hierdie boek. Ek het Johan Smit ontmoet na ‘n skrywe van my in BRIEWE BEELD sowat 3 jaar gelede. Met my eerste besoek aan hom in Edenvale het hy vir my sy skrywes gewys aan tydskrifte en persone. Persone het ingesluit : Dr. Adrio Konig, Dr. Isak Burger, Dr. Bernard Ficker, Dr. Deon Jonker, Prof. J.S. Malan, Prof. A.D. (Andries ) Du Toit en nog vele geleerdes. Nadat ek ‘n paar van sy briewe gelees het en met hom gesels het, was dit soos ‘n soete geur wat ek gekry het, met die wete dat hierdie man ontsaglike kennis het van : Die Bybel en al die variasies van Christenskap, die geskiedenis van die Christelike geloof, asook baie ander gelowe en Godsdienste. Hy het ‘n goeie kennis van die reg en van getuienis lewer in die hof, wat hy baie behendig gebruik as hy getuienisse in die Bybel aanhaal en ontleed. Daar is ook net geen einde aan hierdie man se algemene kennis nie. Om sy briewe te lees dwing net soveel respek en bewondering af as om ‘n meester-kunstenaar te aanskou terwyl hy sy kunswerk skilder of beeldhouwerk doen.
The Finnish mathematician and astronomer Anders Johan Lexell (1740–1784) was a long-time close collaborator as well as the academic successor of Leonhard Euler at the Imperial Academy of Sciences in Saint Petersburg. Lexell was initially invited by Euler from his native town of Abo (Turku) in Finland to Saint Petersburg to assist in the mathematical processing of the astronomical data of the forthcoming transit of Venus of 1769. A few years later he became an ordinary member of the Academy. This is the first-ever full-length biography devoted to Lexell and his prolific scientific output. His rich correspondence especially from his grand tour to Germany, France and England reveals him as a lucid observer of the intellectual landscape of enlightened Europe. In the skies, a comet, a minor planet and a crater on the Moon named after Lexell also perpetuate his memory.
In this companion volume to A Space for Grace, Johan Cilliers delves into some of the most profound theological underpinnings of preaching. Drawing on his extraordinary depth and breadth of scholarship, Cilliers examines the aesthetic, qualitative, and relational dimensions of sermonic time. Faithful preaching, he argues, is an art of speaking the now of grace, which is inextricably linked to past and future, but is simultaneously a dynamic event filled with the revelatory presence of God. Along with helpful reflections on pieces of visual art, Cilliers provides numerous sample sermons, as well as several detailed sermon analyses.
Fine Sediment in Open Water is mainly written for professional engineers working in estuaries and coastal systems. It provides the basis for a fundamental understanding of the physical, biological and chemical processes governing the transport and fate of fine sediment in open water and explains how this understanding can steer engineering studies with numerical models. This is a unique treatment of processes at a variety of spatial and temporal scales, from the micro-scale (colloid scale) to system-wide scales, and from intra-tidal time periods to decades.Beginning with the processes governing the transport and fate of fine sediment in shallow open water, the first eight chapters are dedicated to the hydrodynamic, soil mechanics and biological processes which determine fine sediment concentrations in the water column, in/on the bed and the exchange of sediment between bed and water column. The next two chapters treat the net fluxes of fine sediment as a function of asymmetries in forcing and sediment properties. These fundamental processes form the basis for the subsequent chapters on modeling in which the governing equations are presented, and tools are provided to aggregate and parameterize the various processes elaborated in the first eight chapters. Further, any numerical model study should be based on a conceptual model, as illustrated in the final five chapters, which provide examples of numerical modeling studies on the transport and fate of fine sediment in a coastal sea, an estuary, a tidal river, a lake, and around and within a harbor basin.Related Link(s)
An area of forest the size of England is cut down in the tropics each year. Forestry is responsible for a fifth of global carbon emissions - more than the entire world transport sector. Urgent action to tackle the loss of global forests needs to be a central part of any new international agreement on climate change. Climate Change: Financing Global Forests is an independent report commissioned by the UK Prime Minister to address this vitally important issue. It assesses the impact of global forest loss on climate change and explores the future role of forests in the international climate change framework, with particular emphasis on the role of international finance. It also looks at the economic and policy drivers of deforestation and describes the incentives required to ensure more sustainable production of agriculture and timber in order to meet global demand while reducing carbon emissions. The report draws on a wide range of international expertise and will have significant national, EU and international interest and influence. It includes new modelling and analysis of the global economic impact of continued deforestation and provides a comprehensive assessment of the opportunity and capacity-building costs of addressing the problem. It shows that the benefits of halving deforestation could amount to $3.7 trillion over the long term. However, if the international community does not act, the global economic cost of climate change caused by deforestation could amount to $12 trillion. In this comprehensive and detailed report, Johan Eliasch makes a clear and forceful case for forests to be included in international carbon trading mechanisms. He calls for the international community to support forest nations to halve deforestation by 2020 and to make the global forest sector carbon neutral by 2030.
Over the years, many have signed up for the South African Special Forces selection course but only a select few have ever passed. The gruelling course pushes recruits to their physical and mental limits. Those who make it through selection still have to complete a demanding year-long training cycle before they can join the ranks of this elite unit. In A Breed Apart, former Special Forces operator Johan Raath offers a rare insider's view on the training he and other young soldiers received in the mid-1980s. Drawing on the reminiscences of his fellow Recces, he describes the phases of selection and training, and offers valuable insights into what makes a successful operator. The courses in the training cycle show the range and standard of Special Forces training, including weapons handling, bushcraft/survival, parachuting, demolitions and urban warfare, as well as seaborne and riverine operations. For Raath and his cycle buddies, the training cycle culminated in an operation in southern Angola where the young Recces saw action for the first time. Much of what Raath underwent still forms part of present-day Special Forces training. Comprehensive and revealing, this book shows why these soldiers truly are a breed apart.
Based on a detailed examination of Kyrgyzstan, Johan Engvall goes well beyond the case of this single country to elaborate a broad theory of economic corruption in developing post-Soviet states regionally—as a rational form of investment market for political elites. He reveals how would-be officials invest in offices to obtain access to income streams associated with those offices. Drawing on extensive fieldwork over an eight-year period, Engvall details how these systems work and the major implications this holds for political and economic development in the region. Often identified and criticized simply as obstacles to development by scholars, Engvall instead argues that these systems must be reinterpreted in the context of a standardized and entrenched method of organizing the state. He also shows how private actors have been unsuccessful in buying preferential treatment directly from the state. Instead, public officials have become the predominant conduit to influencing policy process and monitoring the sale of protection, property rights, and other privatized "public" goods.
Introduces the concepts and methods of the Lie theory in a form accessible to the non-specialist by keeping mathematical prerequisites to a minimum. Although the authors have concentrated on presenting results while omitting most of the proofs, they have compensated for these omissions by including many references to the original literature. Their treatment is directed toward the reader seeking a broad view of the subject rather than elaborate information about technical details. Illustrations of various points of the Lie theory itself are found throughout the book in material on applications. In this reprint edition, the authors have resisted the temptation of including additional topics. Except for correcting a few minor misprints, the character of the book, especially its focus on classical representation theory and its computational aspects, has not been changed.
This powerful book shows us that we are in deep denial about the magnitude of the global environmental challenges and resource constraints facing the world. Despite growing scientific consensus on major environmental threats as well as resource depletion, societies are largely continuing with business as usual, at best attempting to tinker at the margins of the problems. The authors argue that regardless of whether governments respond to the economic crisis through additional stimulus packages or reduced government spending, environmental and resource constraints will remain. The crisis will be exacerbated by the combination of climate change, ecosystem decline and resource scarcity, in particular crude oil. The concept of Planetary Boundaries is introduced as a powerful explanation of the limits of the biosphere to sustain continued conventional growth. The book breaks the long silence on population, criticizing donor countries for not doing enough to support the education of girls and reproductive health services. It is shown that an economy built on the continuous expansion of material consumption is not sustainable. De-growth, however, is no solution either. The growth dilemma can only be addressed through a transformation of the economic system. A strong plea is made for abandoning GDP growth as the key objective for development. The focus should instead be on a limited number of welfare indicators. The trickle-down concept is seriously questioned, to be replaced by one of sufficiency. Rich countries are called upon to hold back their material growth to leave room for a rising living standard among the poor. Alternative business models are presented, such as moving from products to services or towards a circular economy based on re-use, reconditioning and recylcing – all with the aim of facilitating sustainable development.

The autobiography of Dutch soccer legend Johan Cruyff, whose remarkable life and impeccable style have influenced star players and clubs for decades Johan Cruyff embodied a footballing philosophy that now dominates coaching and playing styles in all the leading club sides around the world. You can dispute whether Cruyff was the greatest player ever -- he was certainly one of the top three -- but he is undoubtedly the player who single-handedly changed the nature of the game. My Turn tells the story of Cruyff's remarkable career, built on the techniques he learned playing in the streets of postwar Amsterdam while hoping to be noticed by the city's famous club, Ajax. He would eventually inspire that team to eight league championships and three European cups. He won his first of three Ballons d'Or at twenty-four in 1971. In 1973, Cruyff was sold to Barcelona for a world-record transfer fee. He led the Catalans to victory in La Liga for the first time since 1960, and went on to leave a lasting mark on Spanish soccer. In the 1974 World Cup, Cruyff propelled the Dutch team to the final for the first time. Cruyff's lasting influence, however, is not in the medals he won, but in the style of play he epitomized and then applied to the Barcelona and Ajax teams he coached. His vision of "Total Football" transformed the way soccer was played, and its dazzling fluidity became the basis of the most admired sides around the world. He was the sport's uncompromising genius on and off the field of play.
Financial statements give invaluable insights into the performance and future potential of a business. But they do not evaluate the accounting results they reflect. This book offers practical insights into the essential information that financial statements reflect.
Winner of the 2007 Jan Rabie/Rapport Award for fresh, new Afrikaans Prose. "The 2007 Jan Rabie/Rapport Prize was awarded to Johan Engelbrecht for his debut work, 'kaffertjie.' Engelbrecht was commended for his contribution to renewal in Afrikaans literature. Says Dr. Andries Visagie from the University of Kwazulu/Natal and a judge in this category; "Engelbrecht is responsible for one of the most original debut works in Afrikaans literature's history." Justice Edwin Cameron Constitutional Court Judge and Author of Witness to AIDS Sunday Independent: Books Page December 2006 'BEST READS OF THE YEAR' "'kaffertjie, ' by Johan Engelbrecht is a provocatively titled novelization of a most remarkable true story. The writer's childless aunt and uncle - he was a West Rand Conservative Party councilor in the 1980s - took their helper's infant into their doting care when she became permanently institutionalized. The title is eponymous, and is meant to capture the contradictions in this story of love, devotion and (fortunately brief) betrayal across the chasms of racial ignorance and stupidity. The book is already making waves in its Afrikaans appearance.
