One example of ethos is the citations of multiple experts, including psychiatrist Harish Shetty and traumatologist and counsellor Seema Hingorrany. This gives the impression that experts are concerned about the issue raised in the article, and that their opinions support its claims. The article is actually full of expert opinions, going on to include one psychologist who has written a "seminal" book about loneliness, and another who has researched parental alienation. It also includes several less persuasively expert opinions, including two actors.
An example of pathos might be the image of accused shooter James Holmes, with "audacious flaming orange hair," and the ""impassive look with a hint of mockery in it." These images are emotionally disturbing, and, the writer wants to suggest, raise questions about a "dangerous disconnect from reality" that characterizes modern society, especially among young people.
Logos is implicit, but present. The story suggests that because psychologists are suggesting (by no means unanimously) links between alienation and certain social media, films, and other aspects of modern life, that parents ought to watch out for its telltale signs. One of the overall arguments of the article is essentially based on logos: because social media can make a young person more shut off from the outside world, it can or will make them less able to deal with life's challenges when they arise.
