Where to get Business Communication Developing Leaders for a Networked World by Peter W. Cardon ebook

Educating Future Leaders for a Globalized Linked-Up World

Hello, thank you for joining us for this edition of Business Communication. This educational program is aimed at developing leaders who are prepared to succeed in a networked world. Students have a greater chance of reading the text engaging in self-reflection as a result of the practitioner- case-based approach taken by the author. They are in a better position to understwhy credibility is essential to efficient effective business communication in today’s rapidly changing environment for business communication because they are in a better position to understwhy credibility is essential.

Cardon’s integrated solution, which includes the results-driven technology content, provides a contemporary yet traditional view into the field of business communication. This enables instructors to teach fundamental communication principles while also staying up to date with changes in cultural norms technological advancements. Students are given the tools to become leaders in a networked world by mastering foundational concepts, building strong relationships through effective writing, practicing their communication skills anytime anywhere.
The material in this textbook is structured around the traditional themes associated with business communication. These themes include routine messages, persuasive messages, messages conveying bad news, reports, presentations. In addition to the fundamentals, it incorporates contemporary original topics that teachers want need to cover in their classes.

Credibility
This textbook uses credibility or trust as a central principle throughout the entirety of its content because professional success is dependent on the ability to manage work within professional relationships. Throughout the entirety of the book, there is a significant focus on the fundamentals of relationship-building, including personal credibility, emotional intelligence, listening skills. This item starts off with a conversation about credibility, it continues to make references to that topic throughout the book.

The ability to write well helps to build relationships.
It is imperative to have strong writing skills in the workplace in order to successfully build connections a professional brand. The critical thinking, collaboration, productivity in work relationships that are fostered by Cardon’s three-stage writing process are excellent examples of excellence. Cardon is able to develop the skills that are necessary early on in a career by studying more examples of internal messages.

Enhanced Protection Against the Technology
This book takes a more forward-thinking dependable perspective on the various forms of communication technology that will exist in the future. Although virtually all textbooks make some reference to the utilization of social media, the majority of their attention is concentrated on the relatively small portion of social media activities that are concerned with marketing customer relations. This book, on the other hand, adopts a more expansive perspective on the use of social media, one that takes into account communication within teams as well as communication with external partners. Students are better prepared for communication in today’s rapidly changing workplace, which increasingly relies on networked communication. Cardon also discusses the importance of students creating an online professional persona that contributes to the development of their own personal credibility.

Business Focus
Students are given the opportunity to learn how communications can build rich productive relationships between professionals through an approach that is based on business cases. Each chapter starts off with a brief business case, then, in contrast to any other product currently available on the market, examples from the case are woven throughout the chapter into the model documents. This method immerses readers in the narrative that lies behind each every business message.

Forward-Looking Vision Built on Years of Experience
The book adheres to the fundamental principles of business communication that have been developed over many decades. Yet it also goes beyond traditional coverage by including the most recent communication practices that are made possible by communication technologies by providing enhanced coverage of increasingly important business communication topics such as interpersonal communication (Chapters 2, 3, 4), social media technology (Chapters 7 8), crisis communication public relations (Bonus Chapter), oral communication (throughout the book), business plans business proposals (Bonus Chapter) (Bonus Appendix).

Why is it Important to Remember This?
At the beginning of each chapter is a section that outlines the compelling reasons why the content is essential to one’s professional success. These first few paragraphs are meant to gain the students’ buy-in interest in the topic. Students have the opportunity to watch a brief video clip of the author reinforcing this message by scanning a QR code that is located at the beginning of these sections.

Chapter Takeaways
The key points of the chapter are presented in a graphical format. Students are quickly engaged with important chapter content through the use of graphics lists in this resource, which also serves as a reference for students as they apply the principles to their oral written communication.

Specific Brain Cells Linked to Parkinson’s Disease

New research draws a conclusive link between Parkinson’s disease the deterioration of a subpopulation of neurons found within the substantia nigra, a brain region linked to motor control executive functioning.

Scientists have long known that Parkinson’s—a progressive, neurodegenerative condition that currently affects about 1 million people in the United States—is associated with a die-off of dopamine-making neurons in the substantia nigra, but multiple studies going back decades have shown that certain neurons in the area survive well into later stages of the disease. In a paper published yesterday (May 5) in Nature Neuroscience, scientists from the Broad Institute of Harvard MIT reveal why that is: there are ten different types of dopaminergic neurons in the substantia nigra, just one is linked to Parkinson’s.

“This seemed like an opportunity to . . . really clarify which kinds of cells are actually dying in Parkinson’s disease,” study coauthor Evan Macosko, a psychiatrist neuroscientist at the Broad Institute, tells Science News.

See “Study Links Flu to Increased Parkinson’s Risk a Decade Later”

In the study, scientists compared the neuronal diversity in two groups of people who had donated their brains to science: eight who didn’t have Parkinson’s ten who did. Using a technique called single-cell RNA sequencing, which can parse the gene expression activity of individual cells within a tissue sample, the team identified all ten types of neurons—each of which produced dopamine but had different gene expression profiles—in both populations found that there were fewer of only one type within the Parkinson’s group’s brains. That, New Scientist reports, suggests that only that type of neuron died while the Parkinson’s patients were still alive, is likely linked to the disease’s symptoms.

That specificity is “the strength of the paper,” Northwestern University Feinberg School of Medicine neuroscientist Raj Awatramani, who didn’t work on the study, tells New Scientist. He adds that the research “goes right to the core of the matter.”

See “Is It Time to Rethink Parkinson’s Pathology?”

The study authors tell Science News that they hope to replicate the work with a larger number of donor brains so that they can validate their findings perhaps identify other disease mechanisms. In the meantime, they say that their findings could lead to the development of new treatments for Parkinson’s that specifically target or replace the affected cells. Macosko says that stem cell researchers have already reached out, offering to find ways to generate the Parkinson’s-affected neurons.

“If a particular subtype is more vulnerable in Parkinson’s disease, maybe that’s the one we should be trying to replace,” Awatramani tells New Scientist

Corals Sea Anemones Turn Sunscreen into Toxins—Understanding How Could Help Save Coral Reefs


Sunscreen bottles are frequently labeled as “reef-friendly” “coral-safe.” These claims generally mean that the lotions replaced oxybenzone—a chemical that can harm corals—with something else. But are these other chemicals really safer for reefs than oxybenzone? 

Aiptasia anemones do so well in tanks that they’re considered pests in the saltwater aquarium trade.

This question led us, two environmental chemists, to team up with biologists who study sea anemones as a model for corals. Our goal was to uncover how sunscreen harms reefs so that we could better understwhich components in sunscreens are really “coral-safe.”

In our new study, published in Science, we found that when corals sea anemones absorb oxybenzone, their cells turn it into phototoxins, molecules that are harmless in the dark but become toxic under sunlight.

Protecting people, harming reefs

Sunlight is made of many different wavelengths of light. Longer wavelength—like visible light—are typically harmless. But light at shorter wavelengths—like ultraviolet light—can pass through the surface of skin damage DNA cells. Sunscreens, including oxybenzone, work by absorbing most of the UV light converting it into heat.

See “Bleached Corals ‘Sickest’ Scientists Have Ever Seen”

Coral reefs around the world have suffered in recent decades from warming oceans other stressors. Some scientists thought that sunscreens coming off of swimmers or from wastewater discharges could also be harming corals. They conducted lab experiments that showed that oxybenzone concentrations as low as 0.14 mg per liter of seawater can kill 50% of coral larvae in less than 24 hours. While most field samples typically have lower sunscreen concentrations, one popular snorkeling reef in the U.S. Virgin Islands had up to 1.4 mg oxybenzone per liter of seawater—more than 10 times the lethal dose for coral larvae.

Likely inspired by this research a number of other studies showing damage to marine life, Hawaii’s legislators voted in 2018 to ban oxybenzone another ingredient in sunscreens. Soon after, lawmakers in other places with coral reefs, like the Virgin Islands, Palau Aruba, implemented their own bans.

There is still an open debate whether the concentrations of oxybenzone in the environment are high enough to damage reefs. But everyone agrees that these chemicals can cause harm under certain conditions, so understanding their mechanism is important.

Sunscreen or toxin

While laboratory evidence had shown that sunscreen can harm corals, very little research had been done to understhow. Some studies suggested that oxybenzone mimics hormones, disrupting reproduction development. But another theory that our team found particularly intriguing was the possibility that the sunscreen behaved as a light-activated toxin in corals.

To test this, we used the sea anemones our colleagues breed as a model for corals. Sea anemones corals are closely related share a lot of biological processes, including a symbiotic relationship with algae that live within them. It is extremely difficult to perform experiments with corals under lab conditions, so anemones are typically much better for lab-based studies like ours.

We put 21 anemones in test tubes full of seawater under a lightbulb that emits the full spectrum of sunlight. We covered five of the anemones with a box made of acrylic that blocks the exact wavelengths of UV light that oxybenzone normally absorbs interacts with. Then we exposed all the anemones to 2 mg of oxybenzone per liter of seawater.

line of test tubes with anemones for testing oxybenzone toxicity

By putting sea anemones into test tubes with oxybenzone controlling what kinds of light they were exposed to, we could see whether the sunscreen was reacting to light.

The anemones under the acrylic box were our “dark” samples the ones outside of it our control “light” samples. Anemones, like corals, have a translucent surface, so if oxybenzone were acting as a phototoxin, the UV rays hitting the light group would trigger a chemical reaction kill the animals—while the dark group would survive.

We ran the experiment for 21 days. On Day Six, the first anemone in the light group died. By Day 17, all of them had died. By comparison, none of the five anemones in the dark group died during the entire three weeks.

Metabolism converts oxybenzone to phototoxins

We were surprised that a sunscreen was behaving as a phototoxin inside the anemones. We ran a chemical experiment on oxybenzone confirmed that, on its own, it behaves as a sunscreen not as a phototoxin. It’s only when the chemical was absorbed by anemones that it became dangerous under light.

Any time an organism absorbs a foreign substance, its cells try to get rid of the substance using various metabolic processes. Our experiments suggested that one of these processes was turning oxybenzone into a phototoxin.

To test this, we analyzed the chemicals that formed inside anemones after we exposed them to oxybenzone. We learned that our anemones had replaced part of oxybenzone’s chemical structure—a specific hydrogen atom on an alcohol group—with a sugar. Replacing hydrogen atoms on alcohol groups with sugars is something that plants animals commonly do to make chemicals less toxic more water soluble so they are easier to excrete.

chemical reaction turning oxybenzone into a phototoxin

When cells try to process oxybenzone, they replace part of an alcohol group (in red on the left) with a sugar (in red on the right) in doing so turn the sunscreen into a phototoxin.

But when you remove this alcohol group from oxybenzone, oxybenzone ceases to function as a sunscreen. Instead, it holds on to the energy it absorbs from UV light kicks off a series of rapid chemical reactions that damage cells. Rather than turning the sunscreen into a harmless, easy-to-excrete molecule, the anemones convert oxybenzone into a potent, sunlight-activated toxin.

When we ran similar experiments with mushroom corals, we found something surprising. Even though corals are much more vulnerable to stressors than sea anemones, they did not die from oxybenzone light exposure during our entire eight-day experiment. The coral made the same phototoxins from oxybenzone, but all of the toxins were stored in the symbiotic algae living in the coral. The algae seemed to absorb the phototoxic byproducts and, in doing so, likely protected their coral hosts.

We suspect that the corals would have died from the phototoxins if they did not have their algae. It is not possible to keep corals without algae alive in the lab, so we did some experiments on anemones without algae instead. These anemones died about two times faster had almost three times as many phototoxins in their cells compared than the same anemones with algae.

Coral bleaching, ‘reef-safe’ sunscreens, human safety

We believe there are a few important takeaways from our effort to better understhow oxybenzone harms corals.

First, coral bleaching events—in which the corals expel their algal symbionts because of high seawater temperatures or other stressors—likely leave corals particularly vulnerable to the toxic effects of sunscreens.

Second, it’s possible that oxybenzone could also be dangerous to other species. In our study, we found that human cells can also turn oxybenzone into a potential phototoxin. If this happens inside the body, where no light can reach, it’s not an issue. But if this occurs in the skin, where light can create toxins, it could be a problem. Previous studies have suggested that oxybenzone could pose health risks to people, some researchers have recently called for more research into its safety.

See “Sunscreen Ingredients Absorbed into Blood: Study”

Finally, the chemicals used in many alternative “reef-safe” sunscreens contain the same alcohol group as oxybenzone—so could potentially also be converted to phototoxins.

We hope that, taken together, our results will lead to safer sunscreens help inform efforts to protect reefs.

For many animals, genetic diversity is crucial to survival because it affords the population some flexibility when encountering changes in the environment. Individuals may be lost, but variation helps protect whole populations from being wiped out in one fell swoop. Enter the vaquita (Phocoena sinus): the world’s smallest cetacean. These happy-looking porpoises, which occupy a small area in the Gulf of California, are critically endangered, with only 10 individuals estimated to remain in existence, giving conservationists doubts about the species’ survival due to genetic inbreeding.

A study published yesterday (May 5) in Science examined genomic data from archived vaquita tissue samples found that genetic diversity has been low yet stable among the animals for the last 1,000 years or so, indicating that the current lack of variation should not drive the species to extinction. The biggest threat to the vaquita’s continued existence is fishing, as they often become entangled in illegal gillnets.
