Maps are ubiquitous – on phones, in-flight and car displays, and in textbooks the world over. While some maps delineate and name territories and boundaries, others show different voting blocs in elections, and GPS devices help drivers navigate to their destination.

But no matter the purpose, all maps have something in common: They are political. Making maps is about making decisions about what to omit and what to include. They are subject to selection, classification, abstractions and simplifications. And studying the choices that go into maps, as I do, can reveal different stories about land and the people who claim it as theirs.

Nowhere is this more true than in the contested regions that today include modern-day Israel and the Palestinian territories. Since the establishment of the state of Israel in 1948, different governmental and nongovernmental organizations and political interest groups have engaged in what can best be described as “map wars.”

Maps of the region use the naming of places, the position of borders and the inclusion or omission of certain territories to present contrasting geopolitical visions. To this day, Israel or the Palestinian territories may fall off some maps, depending on the politics of their makers.

This is not exclusive to the Middle East – “map wars” are underway across the globe. Some of the more well-known examples include disputes between Ukraine and Russia, Taiwan and China, and India and China. All are engaged in controversies over the territorial integrity of nation-states.

A short history of maps

Traditionally, maps have been used to represent cosmologies, cultures and belief systems. By the 17th century, maps that represented spatial relations within a given territory beaome important to the making of nation-states. Such official maps helped annex territories and determine property rights. Indeed, to map a territory meant to know and control it.

More recently, the tools for making maps have become more broadly accessible. Anyone with a computer and internet access can now make and share “alternative maps” that present different visions of a territory and make varied geopolitical claims.

And maps produced in a conflict region, such as Israel and the Palestinian territories, tell a rich story about the relationship between mapmaking and politics.

Mapping the Middle East

During the British Mandate of Palestine from 1917 to 1947, British surveyors mapped the territories to exercise their control over the land and its people. It was an attempt to supersede the more informal Ottoman land claims of the time.

By the founding of Israel in 1948, only about 20% of the total area of what is known as historic Palestine had been mapped – a fact that has fueled land disputes to this day. The British mapping efforts and their omissions enabled the newly established state of Israel to declare most of the territories as state land, thereby delegitimizing Palestinian land claims.

Maps also helped build the Israeli state. Surveyors and planners mapped the land to allocate land rights, and they helped build the state’s infrastructure, including roads and railroads.

But maps also helped create a sense of nationhood. Maps representing a nation’s shape by delineating its national borders are known as “logo” maps. They can enhance feelings of national unity and a sense of national belonging.

Once established, the Israeli state remade the maps of the region. An Israeli Governmental Names Commission came up with Hebrew names to replace formerly Arab and Christian names for different towns and villages on the official map of Israel. At the same time, formerly Palestinian topographies and places were omitted from the map.

Some Palestinian mapmakers, however, continue to make maps that include Palestinian named sites and depict pre-1948 historic Palestine – an area that stretches from River Jordan in the east to the Mediterranean Sea in the west. Such maps are used to advocate for Palestinians’ right to land and foster a sense of national belonging.

At the same time, Palestinian cartographers who work with the Palestinian Authority – the government body that administers partial civil control over Palestinian enclaves in the West Bank – make official maps of the West Bank and Gaza in the hope of establishing a future state of Palestine. They align their maps with United Nations efforts to map the territories according to international law by demarking the West Bank and Gaza as separate from and as occupied by Israel.

After the 1967 war between Israel and its Arab neighbors, Israel occupied the West Bank and Gaza. As a result, map wars intensified, especially between different fractions within Israel. The left-wing “peace camp,” which was dedicated to territorial compromises with the Palestinians, was pitted against an Israeli right wing committed to reclaiming the “Promised Land” for ensuring Israeli security.

Such incompatible geopolitical visions continue to be reflected in the maps produced. “Peace camp” maps adhere to the delineation of the territories according to international law. For example, they include the Green Line – the internationally recognized armistice line between the West Bank and Israel. Official maps produced by the Israeli government, by contrast, stopped delineating the Green Line after 1967.

Broader and border disputes

Not only have different interest groups and political actors used maps of the region to put forth competing geopolitical claims, but maps have also played a central role in sporadic efforts to establish peace in the region.

The 1993 Oslo Accords, for example, relied on maps to provide the framework for Palestinian self-rule in return for security for Israel. The aim was that after a five-year interim period, a permanent peace settlement would be negotiated based on the borders laid out in these maps.

Consequently, Palestinian planners and surveyors mapped the territory allocated to a future state of Palestine. With the Oslo Accords promising only a future state – but with its borders and level of sovereignty still uncertain – Palestinian experts nevertheless continue to prepare for governing the territories by mapping them.

The Oslo maps are used to this day to delineate geopolitical visions of Israel and a future state of Palestine that are based on international law. But for many Israelis, the Oslo vision of a two-state solution has died – the attack by Hamas, the Palestinian nationalist political organization that governs Gaza, on Israel on Oct. 7, 2023, was its last blow.

The subsequent war between Israel and Hamas, currently subject to a cease-fire, has from the outset involved maps.

In December 2023, the Israeli military posted an online “evacuation map” that divided the Gaza Strip into 623 zones. Palestinians could go online – provided they have access to electricity and internet in a territory plagued by blackouts – to find out whether their neighborhood was called upon to evacuate. Israeli military commanders used this map to decide where to launch airstrikes and conduct ground maneuvers.

But the map served a political aim, too: to convince a skeptical world that Israel was taking care to protect civilians. Regardless, its introduction caused confusion and fear among Palestinians.

Charting a way forward

Maps aren’t just for making sense of the past and present – they help people imagine the future, too. And different maps can reveal conflicting geopolitical visions.

In January 2024, for example, various Israeli right-wing and settler organizations organized the Conference for the Victory of Israel. The aim was to plan for resettling Gaza and increase Jewish settlements in the West Bank. Speakers advocated for transferring Palestinians from the Strip to the Sinai through “voluntary emigration.” With Jewish settlers planning for the return to Gaza, and speakers citing both the Bible and Israeli security for justifications, an oversized map showed the location of proposed Jewish settlements.

Similarly, the Israeli Movement for Settlement in Southern Lebanon has published maps of planned Jewish settlements in Southern Lebanon.

Such maps reveal the desire by some in Israel for a “Greater Israel” – an area described in 1904 by Theodor Herzl, considered the father of modern-day Zionism, as spanning from the brook of Egypt to the Euphrates.

Unsurprisingly, Palestinians make different maps for envisioning the future. Palestine Emerging – a Palestinian and international initiative that brings together various experts, organizations, and funders – uses maps that connect Gaza to the West Bank and the wider region.

Their aim is to transform Gaza into a commercial hub for trade, tourism and innovation and to integrate it into the global economy. Accordingly, maps of urban projects, airports and seaports overlay the cartographic contours of Gaza; and a Gaza-West Bank corridor, which would be sealed for Israeli security, could connect the two geographically separate Palestinian territories.

Such maps reflect the efforts by Palestinian stakeholders to continue surveying the territories that, since the Oslo Accords, were to make up the future state of Palestine.

A new era of expansionist geopolitics

With the current U.S. administration more aligned with right-wing Israeli policies, maps of Greater Israel may guide what Hagit Ofran from Peace Now calls the beginning of a new “Greater Israel” policy period.

Seemingly upending the U.S. governments long-standing policy of supporting a two-state solution in which Gaza would be part of a Palestinian state, Donald Trump on Feb. 4, 2025, floated a plan for the U.S. to “take over” Gaza, moving its current inhabitants out and turning the enclave into “”the Riviera of the Middle East.”

Such a move would amount to another attempt to remake borders across the Middle East. It would not, however, end the “map wars” in Israel/Palestine.The Conversation

George Washington, a real estate investor and successful entrepreneur, knew the difference between running a business and running the government

During his three presidential campaigns, Donald Trump promised to run the federal government as though it were a business. True to his word, upon retaking office, Trump put tech billionaire Elon Musk at the head of a new group in the executive branch called the Department of Government Efficiency.

DOGE, as Musk’s initiative is known, has so far fired, laid off or received resignations from tens of thousands of federal workers and says it has discovered large sums of wasted or fraudulently spent tax dollars. But even its questionable claim of saving US$65 billion is less than 1% of the $6.75 trillion the U.S. spent in the 2024 fiscal year, and a tiny fraction of the nation’s cumulative debt of $36 trillion. Because Musk’s operation has not been formalized by Congress, DOGE’s indiscriminate cuts also raise troubling constitutional questions and may be illegal.

Before they go too far trying to run the government like a business, Trump and his advisors may want to consider the very different example of the nation’s first chief executive while he was in office.

The first businessman to become president

Like Trump, George Washington was a businessman with a large real estate portfolio. Along with property in Virginia and six other states, he had extensive claims to Indigenous land in the Ohio River Valley.

Partly because of those far-flung investments, the first president supported big transportation projects, took an active interest in the invention of the steamboat, and founded the Patowmack Company, a precursor to the builders of the Chesapeake and Ohio Canal.

Above all, Washington was a farmer. On his Mount Vernon estate, in northern Virginia, he grew tobacco and wheat and operated a gristmill. After his second term as president, he built a profitable distillery. At the time of his death, he owned nearly 8,000 acres of productive farm and woodland, almost four times his original inheritance.

Much of Washington’s wealth was based on slave labor. In his will, he freed 123 of the 300 enslaved African Americans who had made his successful business possible, but while he lived, he expected his workers to do as he said.

President Washington and Congress

If Washington the businessman and plantation owner was accustomed to being obeyed, he knew that being president was another matter.

In early 1790, near the end of his first year in office, he reflected on the difference in a letter to the English historian Catharine Macaulay. Macaulay had visited Mount Vernon several years before. She was eager to hear the president’s thoughts about what, in his reply, he described as “the last great experiment for promoting human happiness by reasonable compact.”

The new government, Washington wrote, was “a government of accommodation as well as a government of laws.”

As head of the executive branch, his own powers were limited. In the months since the inauguration, he had learned that “much was to be done by prudence, much by conciliation, much by firmness. Few, who are not philosophical Spectators,” he told his friend, “can realise the difficult and delicate part which a man in my situation (has) to act.”

Although Washington did not say why his situation was delicate, he didn’t need to. Congress, as everyone knew, was the most powerful branch of government, not the president.

The previous spring, Congress had shown just how powerful it was when it debated whether the president, who needed Senate confirmation to appoint heads of executive departments, could remove such officers without the same body’s approval. In the so-called Decision of 1789, Congress determined that the president did have that power, but only after Vice President John Adams broke the deadlock in the upper house.

The meaning of Congress’ vote was clear. On matters where the Constitution is ambiguous, Congress would decide what powers the president can legally exercise and what powers he – or, someday, she – cannot.

When it created a “sinking fund” in 1790 to manage the national debt, Congress showed just how far it could constrain presidential power.

Although the fund was part of the Treasury Department, whose secretary served at the president’s pleasure, the commission that oversaw it served for fixed terms set by Congress. The president could neither remove them nor tell them what to do.

Inefficient efficiency

By limiting Washington’s power over the Sinking Fund Commission, Congress set a precedent that still holds, notably in the 1935 Supreme Court case of Humphrey’s Executor v. U.S.

To the displeasure of those, including Trump, who promote the novel “unitary executive” theory of an all-powerful president, the court ruled that President Franklin D. Roosevelt could not dismiss a member of the Federal Trade Commission before his term was up – even if, as Roosevelt said, his administration’s goals would be “carried out most effectively with personnel of my own selection.”

Like the businessman who currently occupies the White House, Washington did not always like having to share power with Congress. Its members were headstrong and independent-minded. They rarely did what they were told.

But he realized working with Congress was the only way to create a federal government that really was efficient, with each branch carrying out its defined powers, as the founders intended. Because of the Constitution’s checks and balances, the United States was – and is – a government based on compromise between the three branches. No one, not even the president, is exempt.

To his credit, Washington was quick to learn that lesson.The Conversation

5 ways schools have shifted in 5 years since the COVID-19

Published

on

The U.S. educational landscape has been drastically transformed since the COVID-19 pandemic shuttered school campuses five years ago.

Access to high-quality teachers and curriculum developed by teachers is shrinking, for example. Likewise, there has been a loss of emotional support for students and a decline in the school use of technology and social media.

As education scholars focused on literacy practices in schools, here are five ways we believe the COVID-19 pandemic – and the rapid shift to remote learning and back – has transformed education:

1. Teachers are leaving, and those staying are stressed

At the start of the 2024-2025 school year, 82% of U.S. public schools had teaching vacancies.

Schools have tried to adapt by expanding class sizes and hiring substitute teachers. They have also increased use of video conferencing to Zoom teachers into classrooms.

Teacher retention has been a problem for at least a decade. But after the pandemic, there was an increase in the number of teachers who considered leaving the profession earlier than expected.

When teachers leave, often in the middle of the school year, it can require their colleagues to step in and cover extra classes. This means teachers who stay are overworked and possibly not teaching in their area of certification.

This, in turn, leads to burnout. It also increases the likelihood that students will not have highly qualified teachers in some hard-to-fill positions like physical science and English.

2. Increase in scripted curriculum

As of fall 2024, 40 states and Washington had passed science of reading laws, which mandate evidence-based reading instruction rooted in phonics and other foundational skills.

While the laws don’t necessarily lead to scripted curriculum, most states have chosen to mandate reading programs that require teachers to adhere to strict pacing. They also instruct teachers not to deviate from the teachers’ manual.

Many of these reading programs came under scrutiny by curricular evaluators from New York University in 2022. They found the most common elementary reading programs were culturally destructive or culturally insufficient – meaning they reinforce stereotypes and portray people of color in inferior and destructive ways that reinforce stereotypes.

This leaves teachers to try to navigate the mandated curriculum alongside the needs of their students, many of whom are culturally and linguistically diverse. They either have to ignore the mandated script or ignore their students. Neither method allows teachers to be effective.

When teachers are positioned as implementers of curriculum instead of professionals who can be trusted to make decisions, it can lead to student disengagement and a lack of student responsiveness.

This form of de-professionalization is a leading cause of teacher shortages. Teachers are most effective, research shows, when they feel a sense of agency, something that is undermined by scripted teaching.

3. Improvements in teen mental health, but there’s more to do

Many of the narratives surrounding adolescent mental health, particularly since the pandemic, paint a doomscape of mindless social media use and isolation.

However, data published in 2024 shows improvements in teen reports of persistent sadness and hopelessness. Though the trend is promising in terms of mental health, in-school incidences of violence and bullying rose in 2021-22, and many teens report feeling unsafe at school.

Other reports have shown an increase in feelings of loneliness and isolation among teens since the pandemic.

4. Crackdown on students’ technology use in schools

COVID-19 prompted schools to make an abrupt switch to educational technology, and many schools have kept many of these policies in place.

For example, Google Classroom and other learning management systems are commonly used in many schools, particularly in middle school and high school.

These platforms can help parents engage with their children’s coursework. That facilitates conversations and parental awareness.

But this reliance on screens has also come under fire for privacy issues – the sharing of personal information and sensitive photos – and increasing screen time.

And with academia’s use of technology on the rise, cellphone usage has also increased among U.S. teens, garnering support for school cellphone bans.

But banning these devices in schools may not help teens, as smartphone use is nearly universal in the U.S. Teens need support from educators to support them as they learn to navigate the complex digital world safely, efficiently and with balance.

In light of data surrounding adolescent mental health and online isolation – and the potential for connection through digital spaces – it’s also important that teens are aware of positive support networks that are available online.

Though these spaces can provide social supports, it is important for teens to understand the strengths and limitations of technology and receive authentic guidance from adults that a technology ban may prohibit.

5. Students and adults need social emotional support

Students returned to in-person schooling with a mix of skill levels and with a variety of social and emotional needs.

Social and emotional learning includes self-awareness, self-management, social awareness, relational skills and decision-making.

These skills are vital for academic success and social relationships.

Teachers reported higher student needs for social and emotional learning after they returned to in-person instruction.

While some of this social and emotional teaching came under fire from lawmakers and parents, this was due to confusion about what it actually entailed. These skills do not constitute a set of values or beliefs that parents may not agree with. Rather, they allow students to self-regulate and navigate social situations by explicitly teaching students about feelings and behaviors.

One area where students may need support is with cognitive flexibility, or the ability to adapt to current situations and keep an open mind. Classroom instruction that engages students in varied tasks and authentic teaching strategies rooted in real-life scenarios can strengthen this ability in students.

Besides allowing students to be engaged members of a school community, cognitive flexibility is important because it supports the skill development that is part of many state English language arts and social studies standards.

Social and emotional learning and cognitive flexibility are key components that allow students to learn.

Due to vague or confusing state policies, many schools have stopped teaching social and emotional learning skills, or minimized their use.

This, coupled with teacher stress and burnout, means that both adults and children in schools are often not getting their social and emotional needs met.

Message of mistrust

While we described five shifts since the start of the pandemic, the overall trend in K-12 schools is one of mistrust.

We feel that the message – from districts, state legislators and parents – is that teachers cannot be trusted to make choices.

This represents a massive shift. During the initial phase of the COVID-19 lockdown, teachers were revered and thanked for their service.

We believe in teacher autonomy and professionalism, and we hope this list can help Americans reflect on the direction of the past five years. If society wants a different outcome in the next five years, it starts with trust.The Conversation

Daylight saving time and early school start times cost billions in lost productivity and health care expenses

Daylight saving time kicks in on March 9, 2025, but some say it leads to more heart attacks, depression and car accidents.

Investigations into the 1986 Space Shuttle Challenger disaster revealed that key decision-makers worked on little sleep, raising concerns that fatigue impaired their judgment. Similarly, in 1989, the Exxon Valdez oil spill resulted in a massive environmental catastrophe. The official investigation revealed the third mate, in charge of steering the ship, was running on too little sleep, among other problems.

While these specific disasters were not caused by daylight saving time, they are conclusively linked to fatigue, based on postaccident investigations and reports. They underscore the well-documented dangers of sleep deprivation and fatigue-related errors. Yet a vast body of research shows that every year, the shift to daylight saving time needlessly exacerbates these risks, disrupting millions of Americans’ sleep and increasing the likelihood of accidents, health issues and fatal errors.

Imagine a world where one simple decision – keeping our clocks aligned with the natural cycle of the Sun – could save lives, prevent accidents and improve mental well-being. It’s not just about an hour of lost sleep; it’s about how small disruptions ripple through our health, our workplaces and even our children’s futures.

I’m a neurologist who specializes in sleep health. I’ve seen firsthand the negative impacts of poor sleep; it has enormous personal and economic consequences.

Yet despite overwhelming research supporting better sleep policies – such as delaying school start times to align with adolescent biology and the adoption of permanent standard time – these issues remain largely overlooked in public policy discussions.

Sleep deprivation comes with real costs

Chronic sleep deprivation does more than leave people tired. It costs an estimated US$411 billion annually in lost productivity and health care costs. Poor sleep leads to workplace mistakes, car accidents and long-term health issues that strain businesses, families and the economy as a whole.

Fortunately, there’s a fix. Smarter sleep policies – such as permanent standard time and later school start times – can boost efficiency, improve health and save lives.

Up before dawn

Teenagers are the most sleep-deprived age group in the U.S. Multiple studies and surveys show that anywhere from 71% to 84% of high school students report getting insufficient sleep.

This is largely due to early school start times, which force teens to wake up before their biological clocks are ready. If you have a teenager, you probably see it every day: The teen struggling to wake up before sunrise, rushing out the door without breakfast, then waiting in the dark for the school bus.

More than 80% of public middle and high schools in the U.S. start before 8:30 a.m., with 42% starting before 8 a.m. and 10% before 7:30 a.m. As a result, some districts have bus pickups as early as 5 a.m.

Teenagers are going through a natural shift in their circadian rhythms by about two hours. This shift, driven by hormones and biology, makes it hard for them to fall asleep before around 11 p.m. The bodies of teens aren’t wired for these schedules, yet schools and society have designed a system that forces them to function at their worst.

Declining scores, drowsy driving and depression

Sleep-deprived teens have lower grades and test scores, more car crashes caused by drowsy driving, more alcohol and drug use and higher rates of depression, anxiety suicide and aggressive behavior, including carrying weapons.

Along with the health benefits, studies have found that moving school start times to 8:30 am or later could add $8.6 billion to the economy within two years, partly by increased graduation rates.

While concerns about increased transportation costs exist, such as the need for additional buses or drivers due to staggered school start times, some districts have found that optimizing bus routes can offset expenses, making the change cost-neutral or even cost-saving. For instance, a study in Boston found that reorganizing bus schedules using advanced algorithms reduced the number of buses needed and improved efficiency, which allowed high school students to start later and better align with their natural sleep cycles. This change not only supported adolescent sleep health but also saved the district $5 million annually.

More heart attacks, car wrecks and suicide

Every March, most Americans shift their clocks forward for daylight saving time. Studies show this change disrupts sleep and leads to measurable adverse outcomes, including a significant increase in heart attacks. These effects linger for days after the shift, as sleep-deprived workers struggle to adjust.

The mental health impact is also severe. Suicide rates increase in the weeks following the switch, particularly for those already vulnerable to depression.

Unlike daylight saving time, standard time follows the body’s natural circadian rhythm, which is primarily regulated by exposure to sunlight. Our internal clocks are most stable when morning light exposure occurs early in the day, signaling the body to wake up and regulate key biological functions such as hormone production, alertness and metabolism. In contrast, daylight saving time artificially extends evening light, delaying the body’s release of melatonin and making it harder to fall asleep at a biologically appropriate time.

Studies have found that adopting permanent standard time could prevent up to 5,000 suicides annually by reducing seasonal depression, decrease errors, injuries and absenteeism in the workplace and make roads safer, potentially preventing 1,300 traffic deaths each year.

Times are changing

The U.S. tried permanent daylight saving time in 1974. It was so unpopular that Congress repealed it within nine months.

Russia tried it too, in 2011, but switched back three years later. The United Kingdom dropped permanent daylight saving time in 1971 after three years, and Portugal in 1996 after four. All of these countries found that the switch caused widespread public dissatisfaction, health concerns, more morning car accidents and disrupted work schedules. No country is currently on year-round daylight saving time.

These examples provide real-world evidence that permanent DST is undesirable due to public dissatisfaction, safety concerns and negative health effects – all three countries attempted it and ultimately reversed course. Since 2022, there has been renewed debate, largely driven by former U.S. Sen. Marco Rubio’s Sunshine Protection Act, which aims to make DST permanent.

However, the name is misleading because it doesn’t “protect” sunshine but rather eliminates critical morning light, which is essential for regulating circadian rhythms. Major health organizations, along with the National Safety Council, strongly oppose permanent DST due to its well-documented risks.

There are signs that suggest the U.S. is finally waking up to these problems. Out of 13,000 school districts, 1,000 have independently adopted later school start times. California and Florida have enacted laws requiring high schools to start no earlier than 8:30 a.m. California’s mandate went into effect in 2022, and Florida’s is set to begin in 2026.

Permanent standard time and later school start times are not radical ideas. They’re practical, evidence-based solutions based on human biology. Implementing these changes nationally would require congressional action. However, current federal law already allows states to adopt permanent standard time, as Arizona and Hawaii have done, setting a precedent for the rest of the country.The Conversation
