This study guide for Varsity Maths Preparation has been compiled by Emeritus Professor John Webb in response to the dire challenges experienced by first year university students, in Mathematics as well as in courses in Science, Engineering and Business Science, all heavily dependent on mathematical thinking. By working through the problem sets in this self-study book, learners should develop and test their skills, on their own, in areas such as algebraic expertise, trigonometry skills, word problems, geometric insight, numerical facility, logical reasoning and flexible thinking. This cannot be taught and is best achieved without assistance and timeously, i.e. prior to students entering university. The problem-solving techniques which learners could acquire from dedicated, independent use of this outstanding booklet will contribute significantly to their success in the National Benchmark tests (NBTs). Varsity Maths Prep is a gem for learners who are serious about an academic future.

The definitive story of COVID-19 and how global politics shape our health - from a world-leading expert and the pandemic's go-to science communicator

Professor Devi Sridhar has risen to prominence for her vital roles in communicating science to the public and speaking truth to power. In Preventable she highlights lessons learned from outbreaks past and present in a narrative that traces the COVID-19 pandemic - including her personal experience as a scientist - and sets out a vision for how we can better protect ourselves from the inevitable health crises to come.

In gripping and heartfelt prose, Sridhar exposes the varied realities of those affected and puts you in the room with key decision makers at crucial moments. She vibrantly conveys the twists and turns of a plot that saw: deadlier varients emerge (contrary to the predictions of social media pundits who argued it would mutate to a milder form); countries with weak health systems like Senegal and Vietnam fare better than countries like the US and UK (which were consistently ranked as the most prepared); and the quickest development of game-changing vaccines in history (and their unfair distribution)

Combining science, politics, ethics and economics, this definitive book dissects the global structures that determine our fate, and reveals the deep-seated economic and social inequalities at their heart - it will challenge, outrage and inspire.

Reclaim your voice and ignite your confidence with this practical guide from one of Hollywood's top speech coaches

What does power sound like? Loud? Brash? Masculine? Well, it's time to change that.

In this warm and witty manual, Hollywood voice coach Samara Bay offers a compelling approach to asserting your power in all arenas of life. Packed with expert tips and easy-to-follow exercises, Permission to Speak is designed to liberate and inspire even the most tentative of public speakers.

Using in-depth analysis of powerful public figures, from Alexandria Ocasio-Cortez and Michelle Obama to Brené Brown and Lizzo, Bay explodes what we think we know about our voices and how they should sound, and digs deep to the very heart of what they can be.

Permission To Speak shows that women don't have to borrow markers of male leadership to be taken seriously - rather, they can and should be fearlessly, unashamedly themselves.

Gwen Lister is a world-renowned journalist, political activist and free-press advocate. Born in South Africa, she moved to Namibia to pursue her journalism career. She launched (with Hannes Smith) the Windhoek Observer and later, The Namibian.

This memoir chronicles her remarkable life, brave journalism and political activism. 

An acclaimed author and celebrated journalist breaks down the history of electricity and the impact of global energy use on the world and the environment.​

Global demand for power is doubling every two decades, but electricity remains one of the most difficult forms of energy to supply and do so reliably. Today, some three billion people live in places where per-capita electricity use is less than what's used by an average American refrigerator. How we close the colossal gap between the electricity rich and the electricity poor will determine our success in addressing issues like women's rights, inequality, and climate change.

In A Question of Power, veteran journalist Robert Bryce tells the human story of electricity, the world's most important form of energy. Through onsite reporting from India, Iceland, Lebanon, Puerto Rico, New York, and Colorado, he shows how our cities, our money--our very lives--depend on reliable flows of electricity. He highlights the factors needed for successful electrification and explains why so many people are still stuck in the dark.

With vivid writing and incisive analysis, he powerfully debunks the notion that our energy needs can be met solely with renewables and demonstrates why--if we are serious about addressing climate change--nuclear energy must play a much bigger role.

Electricity has fueled a new epoch in the history of civilization. A Question of Power explains how that happened and what it means for our future.

Rooted in the pan-Africanist ideals that animated the struggle against colonialism, regional integration has been on the African agenda for six decades. As soon as African countries attained political independence in the 1960s, they were quick to embrace the need for regional integration because of its strategic value.

The following years saw the adoption of various continental initiatives such as the Southern African Development Community, the Economic Community of West African States, the East African Community and the transformation of the Organisation of African Unity into the African Union.

Regional integration, however, remains elusive. The Quest for Unity is a necessary guide towards efforts for regional integration.

In these vibrant narratives, 25 of the world’s most accomplished movement lawyers and activists become storytellers, reflecting on their experiences at the frontlines of some of the most significant struggles of our time. In an era where human rights are under threat, their words offer both an inspiration and a compass for the way movements can use the law – and must sometimes break it – to bring about social justice.

The contributors here take you into their worlds: Jennifer Robinson frantically orchestrating a protest outside London’s Ecuadorean embassy to prevent the authorities from arresting her client Julian Assange; Justin Hansford at the barricades during the protests over the murder of Black teenager Mike Brown in Ferguson, Missouri; Ghida Frangieh in Lebanon’s detention centres trying to access arrested protestors during the 2019 revolution; Pavel Chikov defending Pussy Riot and other abused prisoners in Russia; Ayisha Siddiqa, a shy Pakistani immigrant, discovering community in her new home while leading the 2019 youth climate strike in Manhattan; Greenpeace activist Kumi Naidoo on a rubber dinghy in stormy Arctic seas contemplating his mortality as he races to occupy an oil rig.

The stories in The Revolution Will Not Be Litigated capture the complex, and often-awkward dance between legal reform and social change. They are more than compelling portraits of fascinating lives and work, they are revelatory: of generational transitions; of epochal change and apocalyptic anxiety; of the ethical dilemmas that define our age; and of how one can make a positive impact when the odds are stacked against you in a harsh world of climate crisis and ruthless globalization.

Phillip is excited when the Germans invade the small island of Curaçao. War has always been a game to him, and he’s eager to glimpse it firsthand–until the freighter he and his mother are traveling to the United States on is torpedoed.

When Phillip comes to, he is on a small raft in the middle of the sea. Besides Stew Cat, his only companion is an old West Indian, Timothy. Phillip remembers his mother’s warning about black people: “They are different, and they live differently.”

But by the time the castaways arrive on a small island, Phillip’s head injury has made him blind and dependent on Timothy.

An essential grief guide and recovery workbook for those who have said, "I thought I'd feel better by now."

Grief does not follow a timeline or a set path. It is nonlinear and messy, doubling back on itself just when you thought you were out of the woods. Those who have experienced the loss of a loved one know this unequivocally, but Western society still seems to think that grief should only last six months to a year-tops-when in fact, grief can last throughout a person's entire life and manifest as serious mental health issues, including depression, anxiety, anger, and despair.

The Long Grief Journey, co-written by a psychotherapist and a clinical psychologist who have both worked with grieving individuals for decades, is for the people who are past the acute pain and effects of a sudden loss and are now learning to live beyond that. It is for those who by all appearances seem to have "moved on." They're working, carrying out their responsibilities, showing up for important life events, yet they quietly bear the weight of their sadness and longing for their loved one. There's a name for this type of long-term, unresolved grief. In fact, there are several: complicated grief, traumatic grief, complex bereavement, prolonged grief, extended grief, abnormal grief, exaggerated grief, and pervasive grief disorder. If you feel "stuck" after experiencing the death of a loved one, even if much time has passed, this book is for you.

With exercises, journal prompts, and rituals that will further help readers along their grief path, The Long Grief Journey is designed to educate, support, and coach you to rekindle a desire to live life fully, all while still cherishing and embracing the memories of your loved one.

THE NUMBER ONE BESTSELLER

'The most important book you’ll ever read… Battle Scars will save lives.' TOM MARCUS, author of SOLDIER SPY

Battle Scars tells the story of Jason Fox’s career as an elite operator, from the gunfights, hostage rescues, daring escapes and heroic endeavours that defined his service, to a very different kind of battle that awaited him at home.

After more than two decades of active duty, Foxy was diagnosed with complex PTSD, forcing him to leave the military brotherhood and confront the hard reality of what follows. What happens when you become your own enemy? How do you keep on fighting when life itself no longer feels worth fighting for?

Unflinchingly honest, Battle Scars is a breathtaking account of Special Forces soldiering: a chronicle of operational bravery, and of superhuman courage on and off the battlefield.

The world is currently experiencing the lowest levels of democracy we have seen in over thirty years. Autocracy is on the rise, and while the cost of autocracy seems evident, it nevertheless remains an attractive option to many.

While leaders like Viktor Orbán disrupt democratic foundations from within, autocrats like Xi Jinping and Vladimir Putin do so from abroad, eroding democratic institutions and values and imperilling democracies that appear increasingly fragile. There are even those who, disillusioned with the current institutions in place, increasingly think authoritarianism can deliver them a better life than democracy has or could.

They're wrong. Autocracy is not the solution - better democracy is. But we have to make the case for it. We have to combat institutional rot by learning from one another, and, at times, from our rivals. And we have to get our own houses in order. Only then can we effectively stand up for democratic values around the world and defeat the dictators.

Over the past century, South Africa’s military has established itself in several defining battles and operations. Preferring manoeuvre over attrition, and often punching above their weight, they have become known for their tenacity, dash, and ability to defy the odds. Their unique command style also sets them apart from other armies and has helped them excel in challenging circumstances.

In 20 Battles, military historians Evert Kleynhans and David Brock Katz investigate how South Africa’s way of war evolved over a 100-year period. They track the evolution of the doctrine and structure of the South African defence forces, rediscovering historical continuity, if any, and the lessons learned in past battles and operations such as Otavifontein, Delville Wood, Southern Ethiopia, Tobruk, Chiusi, Savannah, Cassinga, Cuito Cuanavale and Boleas.

The book also identifies a number of firsts for the defence force, such as the first ever deployment during the 1914 Industrial Strike; the varied deployments across different theatres during both world wars; the first large scale crossborder deployments during the Border War; the first deployment of the new South African National Defence Force after 1994; and, culminating with the recent, and now infamous, Battle of Bangui.

Robben Island is a low-lying outcrop of rock and sand guarding the entrance to South Africa's Table Bay. Although it is just a few kilometres long and a barely swimmable distance from Cape Town, it may well be the most significant historical site in South Africa today.;Paradoxically it symbolises both the repressiveness of the apartheid state and the strength of those who opposed it. While interpretations of the island's history have focused mainly on its role as political prison and on the well-known prisoners held there, such as Nelson Mandela, the island has been put to many and varied uses over the last 500 years: as pantry, hospital, mental asylum, military camp as well as prison. In spite of these various roles there are continuities in its history. Above all, the island has served mainly as repository for those who were considered dangerous to the South African social order. A history of the island provides therefore an off-shore echo of the history of the mainland.

The first authorised biography of eternal legend Elizabeth Taylor.

Known for her glamorous beauty, soap-opera personal life and magnetic screen presence, Elizabeth Taylor was the twentieth century's most famous film star. Including unseen photographs and unread private reflections, this authorised biography is a fascinating and complete portrait worthy of the legend and her legacy.

Elizabeth Taylor captures this intelligent, empathetic, tenacious, volatile and complex woman as never before, from her rise to massive fame at the age of twelve in National Velvet to becoming the first actor to negotiate a million-dollar salary for a film, from her eight marriages and enduring love affair with Richard Burton to her lifelong battle with addiction and her courageous efforts as an AIDS activist.

Using Elizabeth's unpublished letters, diary entries and off-the-record interview transcripts as well as interviews with 250 of her closest friends and family, Kate Andersen Brower tells the full, unvarnished story of the classic Hollywood star who continues to captivate audiences the world over.

A fascinating inside account of the attempt to prosecute former US president Donald Trump.

Mark Pomerantz was a retired lawyer living a calm suburban life when he accepted an offer to join the staff of the district attorney of New York County in February 2021. His brief: to work on the investigation of former president Donald Trump and the Trump Organisation.

Over the next year, Pomerantz interviewed potential witnesses, scrutinised financial records and learned everything he could about Trump's business practices. He finally gathered enough evidence to support the view-held by many of his colleagues on the case-that Trump should be indicted for a number of financial crimes. But that indictment never happened. This book explains why.

In People vs. Donald Trump, Pomerantz tells the story of his unprecedented investigation, why he and his colleague Carey Dunne resigned in protest when Manhattan's district attorney refused to act, and why he believes Donald Trump should be prosecuted. He draws from a lifetime of legal experience to tell a devastating and frequently entertaining story of how prosecutors think, how criminals act, and how the American justice system works-and sometimes doesn't work. It is a cautionary tale that explores how Trump manages to dance between the raindrops of accountability, and how others might bring him to justice.

Economics has the power to make the world a better, happier and safer place: this book shows you how.

Our world is in a mess. The challenges of climate change, inequality, hunger and a global pandemic mean our way of life seems more imperilled and society more divided than ever; but economics can help!

From parenting to organ donation, housing to anti-social behaviour, economics provides the tools we need to fix the biggest issues of today. Far from being a means to predict the stock market or enrich the elite, economics provides a lens through which we can better understand how things work, design clever solutions and create the conditions in which we can all flourish.

With a healthy dose of optimism, and packed with stories of economics in everyday situations, Erik Angner demonstrates the methods he and his fellow economists use to help improve our lives and the society in which we live. He shows us that economics can be a powerful force for good, awakening the possibility of a happier, more just and more sustainable world.

It began with a break-in at the Democratic National Committee headquarters in Washington DC, on 17 June 1972 . Bob Woodward, a journalist for the Washington Post, was called into the office on a Saturday morning to cover the story. Carl Bernstein , a political reporter on the Post, was also assigned. They soon learned this was no ordinary burglary.

Following lead after lead, Woodward and Bernstein picked up a trail of money, conspiracy and high-level pressure that ultimately led to the doors of the Oval Office. Men very close to the President were implicated, and then Richard Nixon himself. Over a period of months, Woodward met secretly with Deep Throat, for decades the most famous anonymous source in the history of journalism. As he and Bernstein pieced the jigsaw together, they produced a series of explosive stories that would not only win the Post a Pulitzer Prize, they would bring about the President's scandalous downfall.

ALL THE PRESIDENT'S MEN documents this amazing story. Taut, gripping and fascinating, it is a classic of its kind -- the true story of the events that changed the American presidency.

The definitive book on the Chinese Communist Party's extensive campaign over the last two decades to take the pole position of global dominance.

For several decades China's ascendancy has been supported by an astonishingly broad and deep portfolio of quiet coercion. Stories of the Chinese Communist Party's authoritarian reach are breathtaking - the gagging of sports stars and huge Western brands; Hollywood self-censorship; infrastructure deals in exchange for political loyalty in multilateral organizations; and of course - communications firms. But these are just the most visible examples.

Beijing Rules exposes the armoury of strategies with which China has exploited Western weakness to position itself as leader in the game of nations: tying market access to political acquiescence; punitive tariffs; online disinformation operations; use of private companies to spy on global users; leveraging vaccines for geopolitical gain; and the crushing of democracy in Hong Kong. With these weapons and dextrous manoeuvrings during the global pandemic, China positioned itself to take its place at the apex of world powers.

Bethany Allen, an internationally recognized investigator into China's covert power, shows Western institutions have bowed to and even enabled Beijing's coercion. As we come reeling out of a global pandemic and eyes are on a new war in Europe, this revealing analysis sounds the alarm about the most significant shift in the new world order, and what we must do to prevent the loss of freedoms we take for granted.

Social work students are often required to take courses in the domain of quantitative literacy, but struggle with the relative inattention to policy and social issues of special significance to professional social workers. These courses, as well as the books written for them, may also present mathematical demands many social workers are unprepared to meet. However, issues such as poverty measurement, adjustment of the purchasing power of social welfare benefits, demographic strains on the Social Security program, and probability theory as a means of estimating the likelihood of child abuse or neglect represent only a few of the many quantitative problems related to the concerns of professional social workers. Written in an accessible style, Social Workers Count provides social workers and those in neighboring disciplines with the background necessary to engage the quantitative aspects of policy and social issues relevant to social work.
