The document summarizes research on how technology and media influence teenagers. It discusses how the internet and cell phones have become central to teenagers' daily lives, with 87% of those aged 12-17 being online. It also explores how media images can negatively impact body image in young girls as early as age 8, and how television and movies portray sex and violence as normal for teenagers. The document aims to shed light on these influences of technology and media on today's youth.

Replacing Photoshop with HTML Prototypes in the Real WorldDennis Kardys
Many clients (and bosses) still clamor for static, finalized Photoshop comps to sign off on. How do you convince them to evolve beyond rigid deliverables and embrace a prototype-based approach to interface design? In this session I’ll share recent experiences upending internal design processes and discarding Photoshop comps in favor of HTML based design guides. We’ll cover practical considerations for getting stakeholder buy-in (and sign-off) and walk through the code you need to start building device-agnostic design systems.
Introducing RequireJS into Large Codebases. Delicately.danielericlee
We're going to talk about how Yammer's JavaScript codebase grew to over 100k lines without any notion of Dependency Management, and how we were recently able to introduce Dependency Management into that codebase in a safe and iterative way.

Technology in its myriad of forms is pervasive in our daily lives. Women interact with technology differently than men and women across the generations use technology for different purposes. This talk will look at how women of all ages use technology to express themselves and engage with the world around them. We will explore the impact of computers, the Internet, mobile devices, video, and other technologies on the ways in which women form and express their identities from childhood through the senior years.
In this talk, delivered to CDC's 2010 STD Prevention conference in Atlanta, Amanda discusses how teens and young adults use tools for electronic and digital communication and what public health workers need to know as they tailor campaigns to a target audience.

Ever wondered why the two hottest words in marketing today are “Millennial” and “Multicultural”?
Well the short answer is that the Millennial Generation (18-34) rules category after category and Multiculturals are their heart and source of vitality and growth.
Andy Halley-Wright, VP Planning and Research at Y&R/Bravo Miami, looks at how despite millennials coming of age in dire economic times, they are optimistic, open minded and brave. And in the home of the brave, the American Dream burns brightest in multicultural millennial hearts. Naturally various life stages and different mindsets fall between the ages of 18 and 34. In fear of over simplification, the younger cohort (18-24) are “Explorers” (4Cs) driven by the mega need of discovery while the older segment (25-34) are “Aspirers” (4Cs) motivated to make a mark and to show the world that they are making it.
"Born in a digital world, eight in 10 Millennials in America own a smartphone. They are always on, always connected – like 1 in 2 are tweeting, liking, emailing, you-tubing or whatever; while on the toilet! No generation has ever spread the word about themselves and help build or break brands like this generation. And again, Hispanics are at the bleeding edge, especially when it comes to mobile," he writes.
If “Millennial” and “Multicultural” are the two hottest words in marketing today, the two most important commandments they impart are that the marketer should “Embrace Diversity” and “Be Participatory.” Of course, that’s easier said than done.
The Millennial Leaders have been identified through the survey as an important new subgroup of the widely-recognized Millennial generation, defined by their expertise with technology, a passion to participate in solving challenges facing communities and the world, and a drive to succeed.
Millennial Leaders are the 11 percent of global Millennials who are driving change through technology. They are found at the intersection of:
Strongly agree they are on the cutting-edge of technology.
Believe they can make a local difference.
Believe they have opportunities in their country to become an entrepreneur or develop and bring an idea to market.

Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.

MANAGEMENT OF ATRIOVENTRICULAR CONDUCTION BLOCK.pdfJim Jacob Roy
Cardiac conduction defects can occur due to various causes.
Atrioventricular conduction blocks ( AV blocks ) are classified into 3 types.
This document describes the acute management of AV block.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
