The air quality within the City Hall subway station in downtown Philadelphia is far worse than on the sidewalks directly above the station. This is certainly one of our key findings latest study published within the Journal of Exposure Science & Environmental Epidemiology.

We are one environmental scientist and a biochemist who assessed the air quality on the fifteenth Street-City Hall station in Philadelphia. We focused on this station because our previous study found that it has highest particulate matter pollution Among Philly's 12 subway stations, we measured the busy Market-Frankford or Broad Street lines.

Most worryingly, there was about ten times more soot contained in the station than at street level. A serious component of that is black carbon, commonly known as soot Fine dust pollution within the air. It is released in the course of the incomplete combustion of fossil fuels and the burning of biomass, and inhalation is linked to adversarial health effects reminiscent of asthma, heart attack and lung cancer.

Our results suggest that the soot is generated by the subway system itself. Graphite is used on brake pads a possible source.

We also found that the concentration of ultrafine particles (UFP) was about 1.7 times higher underground than above ground. While wonderful particles have a diameter of as much as 2.5 micrometers – approx 35 times smaller as a wonderful grain of beach sand – ultrafine particles are 0.1 microns or smaller. These particles are worrisome because they penetrate deep into people's lungs.

Limited access to outside air, frequency of trains, large variety of passengers, and site in the center of downtown could also be among the reasons for the high levels of particulate matter at fifteenth Street Station.

Subway air quality has already been studied in Philadelphia and several other other US cities, including Boston, New York City and Washington, D.C. A study by 71 subway stations in these metropolitan areas found PATH stations New York and New Jersey have the very best concentrations of particulate matter. This study also found the same concentration of wonderful particles, primarily iron and carbon, in Philadelphia, as we found.

However, more types and sizes of particles were measured in our study.

Why it matters

Our study highlights the necessity for Philadelphia to watch air quality in its subways and reduce air pollution exposure for commuters and subway employees.

Several major aspects contribute to air pollution in subways. These include the age of the subway system, wear on the wheels and rails, the frequency of trains, the usage of a graphite lubricant on the brake pads, poor ventilation, the depth of the station, and restrictions on access to outside air and traffic.

Better ventilation, the usage of platform screen doors, and more frequent cleansing to reduce dust are some ways to enhance air quality.

Although we consider that subway air quality must be improved, our results don’t suggest that commuters should avoid the subway. Air pollution levels vary widely between stations and over time, and commuters spend relatively short periods of time in subway stations.

People with health problems, especially lung disease, can provide excellent protection by wearing an N95 mask or N95 mask even a surgical mask. Subway employees can use air purifiers to cut back their exposure to particulate pollution.

How we do our work

Using three forms of monitors, we concurrently measured particle pollution within the underground subway platform and the above-ground pedestrian walkway. In the summer of 2022, we carried out measurements for six hours a day, roughly from 9 a.m. to three p.m., on five weekdays.

What's next?

The next step on this project is to show lung cells within the laboratory to air pollution particles from fifteenth Street Station and measure the oxidative stress attributable to the particles. This stress contributes to chronic diseasesincluding asthma, chronic obstructive pulmonary disease and lung cancer.

We will even study the forms of air particles and the degrees of various metals in them to find out what effects these subway particles have on lung cells.

“Politics is always a local matter,” goes a standard saying. However, additionally it is true that the president has some unique powers.

I’m a Expert in public policy makingand I'm teaching presidential politics at Auburn University this election season. Through my research and teaching of state and federal politics, I've develop into very aware of the importance of the varied races on the ballot this fall.

State and native governments shape our each day experiences in practical ways. State governments determine whether residents Access to expanded Medicaidreproductive care, Parental and family leavethey usually set the state property, sales, and income taxes that all of us pay.

City councils, county governments and college boards determine the standard of our roads, the number of books in class libraries and the costs of utilities comparable to water and sewerage.

Most Americans can have the chance to vote for a wide range of state and native officials in November, but many citizens are turning their attention to a more exciting election: the presidential election.

And it may possibly hardly be denied that the president has a disproportionate influence on American politics.

Personnel for the federal government

So what’s the president doing?

It is actually a busy job that involves tasks comparable to signing executive orders, Conclude contracts, veto or sign bills passed by Congress, function commander-in-chief of the military, and try and construct public support for his or her agenda And Fundraising for the party.

But one other major responsibility is commonly neglected: the allocation of 1000’s of positions in the manager and judicial branches.

The President’s appointment power is an enumerated power, which suggests that it’s enshrined within the US Constitution.

With the expansion of the judiciary and the federal bureaucracy during the last century, the ability of the president has expanded to incorporate 4,000 job changes originally of every termThis doesn’t even bear in mind positions that develop into vacant in the course of the president's term in office – for instance, when a federal judge retires or dies.

Perhaps probably the most well-known presidential appointment power is the ability to nominate Supreme Court justices. These nominations are often highly political and dramatic affairs. This is because their irregular And often sudden timing and the high demands related to a lifelong appointment.

Some presidents may not exercise this supreme power as much as they need. But they’ll still fill many other judicial offices in district courts, appellate courts, and other federal courts.

The Founding Fathers insisted that the manager's power to appoint was not unilateral, as Federalist Paper 76 by Alexander Hamilton. The President nominates people for 1,200 of a very powerful positions, who’re then confirmed – or not – from the US Senate.

The founding fathers saw this as a crucial prerequisite for stopping the tyranny of a single actor, which they’d only just left behind with a lot effort under English rule.

Assembling a cupboard

Among probably the most significant of those appointments are members of the Presidential Cabinet.

Much like a head football coach assembles a team of assistants to implement his vision, the president assembles a team of political champions to 15 Executive Departments within the federal bureaucracy.

Each department is headed by a “secretary,” who’s appointed by the president and confirmed by the Senate. The president consults with cabinet members in regular meetings, but otherwise the secretaries enjoy considerable autonomy. For this reason, the president tries to pick out cabinet members who share his political beliefs.

Much of the agenda for which presidents deserve credit is definitely achieved by departments. For example, in the course of the current Biden administration, the Department of Labor increased guaranteed Overtime payThe Ministry of Health really helpful making marijuana a legal but regulated drug, and the Ministry of Education launched an initiative to take care of the rise in chronic absence.

Cabinet members often stay under the radar of the media and, consequently, the voters, with few exceptions. Transport Minister Pete Buttigieg made headlines At the start of 2024, he announced a brand new Federal Rule which supplies passengers an instantaneous money refund if their flight is cancelled or delayed. President Barack Obama's Secretary of Education Arne Duncan was known for his Bus trips to advertise the economic value of educationPresident George W. Bush's Secretary of State Condoleezza Rice led the remarkable Nuclear agreement between the US and India in 2008.

Crisis manager on the phone, ad hoc

In addition, presidents have the ability to profoundly impact the lives of their constituents by serving as a unifying figure in national crises—a job that distinguishes the president from other elected officials.

These crises, which were unexpected on the time of the election, require the President to quickly calm a desperate nation. After the terrorist attacks of September 11, for instance, President George W. Bush gave a speech which acknowledged the grief of Americans while offering a robust guarantee that the United States wouldn’t cave in to terrorists. President Donald Trump set the direction for a national response to an unprecedented global pandemic. President Bill Clinton expressed warm words on the memorial service for the victims of the bombing of the Alfred P. Murrah Federal Building in Oklahoma City, Oklahoma. And Obama paid tribute to the victims a racially motivated shooting at a church in Charleston, South Carolina.

Presidential candidates cannot, in fact, campaign on their ability to unforeseeable, unexpected situationsInstead, they tout personal qualities that may enable them to steer the nation through the following 4 years – whatever they could bring.

During the last 2024 Presidential debate between the Democratic candidate Kamala Harris and the Republican candidate Donald Trump, the candidates tried to exhibit qualities comparable to Strength, humor and mental acuity – all of this can prove invaluable, whatever the following 4 years hold for us.

This November, voters can have to make a choice from a various range of candidates, from mayor to president, each of whom holds necessary positions.

Federal, state, and native governments work together to shape our perceptions — positive or negative — of the role of public policy in our lives. I encourage voters to concentrate to the candidates at the highest of the ballot in addition to those lower down.

When “Murder: Life on the Street“ premiered on NBC in 1993, most police dramas on network television were formulaic, cleanly shot, and had a transparent line between good and evil.

Homicide was different. There were cops, but you couldn't all the time tell in the event that they were the great guys or the bad guys; the writers played with traditional episodic formats; and the scenes were shot on location with handheld cameras to offer the show a sensible feel.

While television fans have long revered the series as a classicfew viewers looked as if it would notice or care through the series’ first broadcast. “Homicide” suffered from low rankings, interference from network executives at NBC and the constant threat of cancellation.

Now finally available to stream on Peacock, Homicide's groundbreaking visual effects and daring script set the template for twenty first century television, a golden era of programming sometimes known as Platinum TV or Top television.

Up close and private

Paul Attanasio created “Homicide” and based the series on David Simon’s 1991 book, “Murder: A year on the streets of death.” Simon, then an area reporter for The Baltimore Sun, wrote the book about his experiences within the Baltimore Police Department’s homicide squad.

But it was executive producer Barry Levinson who designed the show's haunting style.

Born in Baltimore, Levinson desired to capture town in all its raw glory, with shots full of cigarette smoke, crumbling row houses and the smallest details of law enforcement officials' each day lives.

He did this by photographing on 16 mm film, which a favourite of documentary filmmakers. When developed, the film's natural grain and imperfections are preserved. Editors then added jump cuts to offer the show, within the words of showrunner Tom Fontana“an energy and a surprise.”

At the identical time, the authors avoided spectacular chases and as a substitute handled the thankless and morally questionable points of police work, which may result in cynicism among the many law enforcement officials themselves and towards the occupation as an entire.

Scenes were often filmed multiple times, from different angles and with different focuses. Many of them featured extreme close-ups to force the audience to think in regards to the psyche of the law enforcement officials or the criminals, an approach that gave the series a Cinema Veriteor documentary feeling.

Take the Box, for instance. The windowless room where law enforcement officials disguise and interrogate suspects appears in several episodes, and the filmmakers were keen to create the claustrophobic atmosphere and look of an actual interrogation room.

In fact, probably the most famous episodes of the show, “Three men and Adena“, which revolves across the investigation into the rape and murder of eleven-year-old Adena Watson, takes place almost entirely within the box.

A brand new type of police thriller

Combined with its unique visual style, Homicide structured its episodes to higher reflect the rhythm of actual police work.

Most police series follow the same pattern: During the cold open, a murder is uncovered. At the top of the episode, the murderer is caught.

But that’s not how crime works – and that was also true of “Homicide.”

In the series, crimes may appear originally of an episode, in the center, at the top, or by no means. Murder investigations may span a single episode or, as a precursor to serialization, multiple episodes.

An episode from season six, “The subway” begins with a person being pushed off a train platform. He is trapped between a Baltimore Metro train and the platform, his spine severed. He has about an hour to live, and homicide detectives have an episode to determine who pushed him and why.

On the opposite hand, several episodes of the primary season investigated the rape and murder of Adena Watson. As the season progressed, the police got closer and closer to her attacker, but without finding the essential evidence to convict him.

Like the box, “the board“” was a recurring catchphrase. On a white board behind the precinct, cases were listed in sequence, with cases written in black being considered “closed” while cases written in red were considered “open.” Since murder investigations may very well be several episodes long, the board was a way for each the cops and viewers to maintain track of open and closed cases.

Not all cases were modified from black to red at the top of the episode; in reality, murders were often never solved.

This had the effect of pushing back the finality of the 60-minute television episode, while at the identical time highlighting the futility of police work. Two a long time later:Battlestar Galactica” would use the same counting system, with the number on this white board represents the number of individuals still alive when robots tried to wipe out humanity.

Death and Resurrection

“Homicide” was canceled in 1999 because of low rankings. Nonetheless, it served as a launching pad for the solid and crew and the prestige shows that grace television screens today.

His shooting star, André Braugherwho later played the favored role of Raymond Holt in “Brooklyn Nine-Nineplayed an excellent detective combating his faith and determination. The series also starred Richard Belzer, who would later have an extended role in Law & Order: SVU. Even Robin Williams and a young Jake Gyllenhaal appeared together. in the identical sequence.

“Homicide” was the spiritual predecessor of prestigious television series corresponding to “The Sopranos”, “The shield” And “breaking Bad.” Members of the solid and production team of the series later created “The Wire,” which many critics considered the best television series of all time.

Due to conflicts over music rights and the high costs of adapting the show in HD and 4K resolution, “Homicide” entered purgatory within the age of streaming, whilst successful series from the Nineties has found a brand new home on various platformsMemories of the series faded, overshadowed by the sequel “The Wire”.

With all 122 episodes and the TV movie on their approach to Peacock, the show can finally be introduced to a brand new generation of viewers.
