Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Input: Consider Input: Context: Survivors of acute respiratory failure commonly experience long-term psychological sequelae and impaired quality of life. For researchers interested in general mental health, using multiple condition-specific instruments may be unnecessary and inefficient when using the Medical Outcomes Study Short Form (SF)-36, a recommended outcome measure, may suffice. However, relationships between the SF-36 scores and commonly used measures of psychological symptoms in acute survivors of respiratory failure are unknown. Our objective is to examine the relationship of the SF-36 mental health domain (MH) and mental health component summary (MCS) scores with symptoms of depression, anxiety, and post-traumatic stress disorder (PTSD) evaluated using validated psychological instruments. We conducted a cross-sectional analysis of 1,229 participants at 6- and 12-month follow-up assessment using data from five studies from the United States, the United Kingdom, and Australia. Symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS), Depression Anxiety Stress Scales, the Davidson Trauma Scale, Impact of Event Scale (IES), and IES-Revised (IES-R). At 6-month assessment there were moderate to strong correlations of the SF-36 MH scores with HADS depression and anxiety symptoms (r=-0.74 and -0.79) and with IES-R PTSD symptoms (r=-0.60) in the pooled analyses. Using the normalized population mean of 50 on the SF-36 MH domain score as a cut-off, positive predictive values were 16 and 55% for substantial depression; 20 and 68% for substantial anxiety (Depression Anxiety Stress Scales and HADS, respectively); and 40, 44, and 67% for substantial PTSD symptoms (IES-R, IES, and Davidson Trauma Scale, respectively). Negative predictive values were high. The area under the receiver operating characteristics curve of the SF-36 MH score was high for depression, anxiety, and PTSD symptoms (0.88, 0.91, and 0.84, respectively). All results were consistent for the MCS, across the individual studies, and for the 12-month assessment. For researchers interested in general mental health status, the SF-36 MH or MCS offers a strong measure of psychological symptoms prevalent among survivors of acute respiratory failure. For researchers interested in specific conditions, validated psychological instruments should be considered.

Input: Consider Input: Context: Ever since the death of their teenage daughter Emily, Doug (James Gandolfini) and Lois (Melissa Leo) Riley have been drifting apart. Because of her grief, Lois has become a cold and distant agoraphobic. Doug begins an affair with Vivian, a younger local waitress. However, Lois manages to maintain her appearance and the presentation of her home despite never leaving and inviting no guests aside from her sister, Harriet. She has even already had headstones put next to their daughter's for them both and made funeral plans. One morning, Doug is informed that Vivian has died, and he travels to New Orleans on a business trip to clear his head. Instead, however, he ends up in a strip club where he meets 16-year-old stripper, Mallory (Kristen Stewart). He politely turns down her offer for a private dance and refuses any sexual contact, but instead accompanies her home and makes an unusual proposition: if Mallory will allow him to stay in her run-down house long enough to straighten himself out, he will pay her $100 a day for her trouble. For Mallory, who isn't used to getting money for doing nothing, it seems like a great deal. She accepts and Doug phones home to tell Lois he won't be coming home for a while. She tells him that she knew about his affair with Vivian but before the conversation can go any further, she hangs up. As time passes, Doug and Mallory settle into an unconventional kind of domesticity, and he becomes more of a father figure for her than anything else including teaching her how to make a bed properly and taking care of her money. Meanwhile, back home, Lois realizes that she'll have to act fast in order to save her marriage, even if that means venturing outside for the first time in nearly a decade. After a couple of attempts, Lois manages to start up her car and get on the freeway heading south. One night, Doug gets a call from Mallory who is in trouble after being robbed of the money she carries around by a client. He goes to pick her up and after arguing about how stupid she's being, he makes her realise that she needs to make some changes before things get worse. The following morning, Lois arrives in town and calls Doug to let him know, who is stunned that she not only left the house but drove all the way instead of flying. He immediately goes to meet her and they embrace one another for the first time in years. On the drive back, he tells her about Mallory (whose real name is Alison) and what she does for a living, which Lois instantly disapproves of. She is shocked to learn how young and foul-mouthed Mallory is. However, like Doug, Lois quickly warms to her due to her striking similarities to Emily. Before long, Lois has also moved in to Mallory's home and the three start to form an unconventional family. Lois helps her out with female problems and takes her shopping to buy suitable underwear, making her feel like a mother again, which she enjoys dearly. But later on when Lois attempts to steer Mallory from the path of self-destruction, the young girl flees. Mallory is then later arrested an altercation with a client, and Doug and Lois rush to be by her side, but shortly after they bail her out, she runs again. In that moment, Doug and Lois realize they cannot use Mallory as a substitute for their daughter and return home to Indianapolis. A few days later, Doug receives a phone call from Mallory in Houston. She looks cleaned up and healthier, and announces her plans about moving to Las Vegas, just before boarding the bus. Doug tells her that he and Lois will always be there for her. 
 Question: Who does Doug move in with after Vivian' death
