The U.S. Census Bureau has reported that 56.7 million Americans had some type of disability in 2010, which represents 18.7 percent of the civilian noninstitutionalized population included in the 2010 Survey of Income and Program Participation. The U.S. Social Security Administration (SSA) provides disability benefits through the Social Security Disability Insurance (SSDI) program and the Supplemental Security Income (SSI) program. As of December 2015, approximately 11 million individuals were SSDI beneficiaries, and about 8 million were SSI beneficiaries. SSA currently considers assistive devices in the nonmedical and medical areas of its program guidelines. During determinations of substantial gainful activity and income eligibility for SSI benefits, the reasonable cost of items, devices, or services applicants need to enable them to work with their impairment is subtracted from eligible earnings, even if those items or services are used for activities of daily living in addition to work. In addition, SSA considers assistive devices in its medical disability determination process and assessment of work capacity. The Promise of Assistive Technology to Enhance Activity and Work Participation provides an analysis of selected assistive products and technologies, including wheeled and seated mobility devices, upper-extremity prostheses, and products and technologies selected by the committee that pertain to hearing and to communication and speech in adults.

In the world of thirteen-year-old girls, everything’s fine—at least on the surface. Isabelle Lee is a typical, wisecracking, middle-of-the-pack girl who just happens to be dealing with some big issues. Her father has died and no one—especially her mother—wants to talk about it. Meanwhile, Isabelle’s sister, who “used to be nine and charming,” has messed everything up by ratting Isabelle out to their mom about her eating disorder. At school, there’s Mr. Minx, the self-important (but really not bad) English teacher; Ashley Barnum, the prettiest girl around; and the lunchroom, where tables are turf in an all-eyes-open battle for social status. Isabelle has measured the distance to being cool and she thinks it’s long shiny hair, a toothpaste smile, and perfectly broken-in size-zero jeans. Perfect is the story of one girl’s attempt to cope with loss, define true friendship, and figure out the difference between appearances and reality.

The mysterious connection between a teacher’s disappearance and an unsolved code in a children’s book is explored in this new novel from the “modern Agatha Christie” (The Sunday Times, London) and author of The Appeal. Forty years ago, Steven “Smithy” Smith found a copy of a famous children’s book by disgraced author Edith Twyford, its margins full of strange markings and annotations. When he showed it to his remedial English teacher Miss Iles, she believed that it was part of a secret code that ran through all of Twyford’s novels. And when she later disappeared on a class field trip, Smithy becomes convinced that she had been right. Now, out of prison after a long stretch, Smithy decides to investigate the mystery that has haunted him for decades. In a series of voice recordings on an old iPhone, Smithy alternates between visiting the people of his childhood and looking back on the events that later landed him in prison. But it soon becomes clear that Edith Twyford wasn’t just a writer of forgotten children’s stories. The Twyford Code holds a great secret, and Smithy may just have the key. “Filled with numerous clues, acrostics, and red herrings, this thrilling scavenger hunt for the truth is delightfully deceptive and thoroughly immersive” (Publishers Weekly, starred review).

This Code of Practice for Victims of Crime forms a key part of the wider Government strategy to transform the criminal justice system by putting victims first, making the system more responsive and easier to navigate. Victims of crime should be treated in a respectful, sensitive and professional manner without discrimination of any kind. They should receive appropriate support to help them, as far as possible, to cope and recover and be protected from re-victimisation. It is important that victims of crime know what information and support is available to them from reporting a crime onwards and who to request help from if they are not getting it. This Code sets out the services to be provided to victims of criminal conduct by criminal justice organisations in England and Wales. Criminal conduct is behaviour constituting a criminal offence under the National Crime Recording Standard. Service providers may provide support and services in line with this Code on a discretionary basis if the offence does not fall under the National Crime Recording Standard (NCRS) (see the glossary of key terms found at the end of this Code). Non-NCRS offences include drink driving and careless driving. This Code also sets a minimum standard for these services. Criminal justice organisations can choose to offer additional services and victims can choose to receive services tailored to their individual needs that fall below the minimum stand
