P U R E Z A
Mrs. Pureza’s son, Abel, left Maranhão with great plans, but ended up as a victim of modern slavery inside a farm in the southeast of Pará. Similar stories are shared by many workers coming from different Brazilian states, mostly in the Northeast of the country, such as Maranhão, Piauí, Ceará and Bahia. The protagonists of many of these stories end up becoming numbers, or not even that, they simply “disappeared into the world”.
With the lack of news from her son, Pureza did not observe this situation inertly, but instead waged a colossal struggle, probably much greater and more complex than she could have imagined when she started the three-year journey in search of her son.
Clues led Pureza to a farm where she was able to unmask a major modern slavery scheme. With immense courage, she was able to change not only the life of her son but also lives connected to several other families and friends, bringing into focus the violation of human rights happening openly in Pará. A region that has been made invisible on the national scene and even more ignored on an international scale.

Wangari Maathai
Wangari Maathai, in full Wangari Muta Maathai, (born April 1, 1940, Nyeri, Kenya—died September 25, 2011, Nairobi), Kenyan politician and environmental activist who was awarded the 2004 Nobel Prize for Peace, becoming the first Black African woman to win a Nobel Prize.
Maathai was educated in the United States at Mount St. Scholastica College (1964) and at the University of Pittsburgh (M.S., 1966). In 1971 she received a Ph.D. at the University of Nairobi, effectively becoming the first woman in either East or Central Africa to earn a doctorate.
Maathai developed the idea that village women could improve the environment by planting trees to provide a fuel source and to slow the processes of deforestation and desertification. The Green Belt Movement, an organization she founded in 1977, had by the early 21st century planted some 30 million trees. Leaders of the Green Belt Movement established the Pan African Green Belt Network in 1986 in order to educate world leaders about conservation and environmental improvement.
In addition to her conservation work, Maathai was elected to Kenya’s National Assembly in 2002 with 98 percent of the vote, and in 2003 she was appointed assistant minister of environment, natural resources, and wildlife. When she won the Nobel Prize in 2004, the committee commended her “holistic approach to sustainable development that embraces democracy, human rights, and women’s rights in particular.” She published an autobiography, Unbowed, in 2007. Another volume, The Challenge for Africa (2009), criticized Africa’s leadership as ineffectual and urged Africans to try to solve their problems without Western assistance. Maathai was a frequent contributor to international publications such as the Los Angeles Times and the Guardian.

Sprowston mother in stand-off with school over bullying
By David HannantDHannant87Specialist reporter: health and education
A Sprowston mother is locked in a stand-off with her daughter's school after keeping her at home for the past six weeks to avoid what she describes as "brutal" bullying.
Rebecca Everson says the treatment her 12-year-old daughter Phoebe suffers has become so severe that the youngster has been left "a shell of a girl".
She says the Year 8 Sprowston Community Academy pupil is subjected to cruel messages on social media platforms like Whatsapp, Instagram and Snapchat and has abuse hurled at her by classmates regularly.
After raising her concerns with school leaders, Ms. Everson said her daughter's issues only got worse so for the past six weeks she has refused to send her in. However, she now claims the school is threatening her with fines over Phoebe's attendance record.
She said: "The bullying Phoebe has suffered has been awful. They send her messages calling her every name under the sun. It is brutal.
"I have rung the school and told them she does not feel safe at school and requested work to be sent home for her, but they have done nothing."
Ms. Everson the issue started in October last year, which she reported to Phoebe's teachers.
She said: "The school said they would talk to the girls involved, but when they did it just aggravated the situation.
"Some of the girls involved in the cyberbullying attend other schools nearby too, so moving schools is just not viable.
"Phoebe is a shell of the girl she was before this all began. She has done nothing to deserve this but now she's terrified to even go to school.
"I just feel like I'm going around and around in circles trying to get something done - it's terribly awful."
Sprowston Community Academy was approached for comment but said the school was unable to comment on individual cases.

Implications of English as an International Language for Language Pedagogy
The position of the English language in the world has recently underwent an enormous shift. Much literature has been written about what English as an International Language (EIL) actually is (e.g. Alsagoff et al., 2012; Matsuda, 2003; McKay and Brown, 2016; Sharifian, 2009), ranging from a view of EIL as the many varieties of English that are spoken today to the use of English by second language speakers of English. Thus, EIL is viewed both as a type of English and as a way of using English (Cameron & Galloway, 2019).
In addition, the global spread of English has altered its status from being a homogeneous and standard language spoken by a few powerful countries into an international language or lingua franca spoken by a wide variety of speakers around the world (Llurda, 2004; Galloway & Rose, 2017). Crystal (1997) stated that “if there is one predictable consequence of globalization of a language, it is that nobody owns it anymore” (p. 2). Various studies (e.g. Llurda, 2017; Marlina, 2018; Schuttz, 2019) have widely argued that English does not belong only to native-speaking communities because the number of people who currently speak English as a second/foreign language exceeds that of native English speakers. Seidlhofer (2003) asserted that “English is being shaped at least as much by its nonnative speakers as by its native speakers” (p. 339).

7 Tips to Launch Your Product Using a Teaser Campaign
As a small business, there can be a lot of pressure to ensure a product launch goes well. Sometimes the fortunes of the business are
directly linked to the successful launch of a new product or service. This can put a lot of pressure on a communications team tasked
with getting maximum reach and reward ahead of a launch. In the automotive industry, there’s a long and dubious history behind the
protracted teaser campaign. A ‘leak’ is almost always written with inverted commas. And leading publications have a rendering
specialist on hand to stitch teased images together into the final product, usually with mixed results. Behind the teaser is the need for
the brand to maximize conversation and reach through social engagement. The reality is, some industries are more open to a teaser
than others. But the industries that are open to a good teaser campaign may surprise you. Cars, motorcycles, video games, books,
films are all pretty obvious candidates for a half decent teaser campaign. How many of us have stayed past the credits at the end of
a Marvel film just to see the teaser for the next film? (The Deadpool teaser is still one of my favorites.) You may ask, what do all of
these teaser campaigns have in common? The answer is, they have dedicated fans that lap up the intimate details and enjoy the
tease that only drip-fed information provides. So if your industry has fans who eagerly await every announcement, no matter how
small, then chances are a teaser campaign will work well for your brand. From the outside looking in, some of these teaser campaigns
look chaotic. But that’s not the case at all.

Rescuers spotted debris from the tourist submarine Titan
on the ocean floor near the wreck of the Titanic on June
22, 2023, indicating that the vessel suffered a catastrophic
failure and the five people aboard were killed. Below, Purdue
University professor Nina Mahmoudian talks about vehicles
for deep ocean research.
Nina Mahmoudian: When we talk about water studies,
we’re talking about vast areas. And covering vast areas
requires tools that can work for extended periods of time,
sometimes months. Having people aboard underwater
vehicles, especially for such long periods, is expensive and
dangerous.
One of the tools researchers use is remotely operated
vehicles, or ROVs. Basically, there is a cable between the
vehicle and operator that allows the operator to command and
move the vehicle, and the vehicle can transmit data in real
time. ROVs can reach deep ocean — up to a depth of 6,000
meters. It’s also better able to provide the mobility necessary
for observing the sea bed and gathering data.
Autonomous underwater vehicles provide another
opportunity for underwater exploration. They are usually not
tied to a ship. They are typically programmed ahead of time
to do a specific mission. And while they are underwater they
usually don’t have constant communication. At some interval,
they surface, relay the data that they have gathered, change
the battery or recharge and receive renewed instructions
before again submerging.
Crewed1
submersibles will be exciting for the public and
those involved. However, they will be much more expensive
compared with uncrewed explorations because of the required
size of the platforms and the need for life-support systems. So,
uncrewed vehicles provide better opportunities for exploration
at less cost and risk in operating in inhospitable locations.
Using remotely operated and autonomous underwater
vehicles gives operators the opportunity to perform tasks that
are unsafe for humans, like observing under ice and detecting
underwater mines.
