Offers parents strategies for coping with the increasing presence of digital and mobile media and for managing new technology for their children, and examines how approaches differ among families according to income.

New technologies offer new ways for families to connect, access ideas and entertainment, and manage the risks faced by children and teens, but they also bring more responsibilities, choices and challenges. 'The Parent App' explores these differences and provides the kind of guidance backed by thorough research that parents today desperately need.

WatchKit App Development Essentials is intended for readers with some existing experience of iOS development using Xcode and the Swift programming language. Beginning with the basics, this book provides an introduction to WatchKit apps and the WatchKit app development architecture before covering topics such as tables, navigation, user input handling, image handling, animation, maps and menus. More advanced topics are also covered throughout the book, including communication and data sharing between a WatchKit app and the parent iOS app, working with custom fonts and the design and implementation of custom notifications. As with all the books in the “Development Essentials” series, WatchKit App Development Essentials takes a modular approach to the subject of WatchKit app development for the Apple Watch, with each chapter covering a self-contained topic area consisting of detailed explanations, examples and step-by-step tutorials. This makes the book both an easy to follow learning aid and an excellent reference resource.

The production of this book represents a culmination for me of some 25 years of interest in the field of personality and substance use and abuse. In choosing the field of substanceuse and abuse for the focus of our research, all of the investi- tors collaborating in this research have been sustained by the awareness that the work we are doing has an important purpose. Substance abuse continues to have enormous impacts on individuals and families,and prevention and treatment - proaches developed to date have not always been as successful as we would hope to see. New advances in our fundamental understanding of the causal mec- nisms involved in the development ofaddiction may be necessary to advance our success in developing new forms of prevention and treatment for alcohol and drug abuse. The work in this book builds on the work of numerous previous investi- tors who have been drawn to investigate this topic. As you will notice in the extensive reference list, there have been hundreds of articles published on this topic. Although each of these references has added a small piece to our und- standing of the relationship between personality and alcohol abuse, the majority of these studies have been done on clinical samples and often involved no control groups or poorly matched control groups. Several important previous longitu- nal investigations have been conducted,but these investigations have usually not included general population samples or comprehensivepersonality test batteries.

Fully updated for Android Studio Iguana (2023.2.1) and the new UI, this book teaches you how to develop Android-based applications using the Kotlin programming language. This book begins with the basics and outlines how to set up an Android development and testing environment, followed by an introduction to programming in Kotlin, including data types, control flow, functions, lambdas, and object-oriented programming. Asynchronous programming using Kotlin coroutines and flow is also covered in detail. Chapters also cover the Android Architecture Components, including view models, lifecycle management, Room database access, content providers, the Database Inspector, app navigation, live data, and data binding. More advanced topics such as intents are also covered, as are touch screen handling, gesture recognition, and the recording and playback of audio. This book edition also covers printing, transitions, and foldable device support. The concepts of material design are also covered in detail, including the use of floating action buttons, Snackbars, tabbed interfaces, card views, navigation drawers, and collapsing toolbars. Other key features of Android Studio and Android are also covered in detail, including the Layout Editor, the ConstraintLayout and ConstraintSet classes, MotionLayout Editor, view binding, constraint chains, barriers, and direct reply notifications. Chapters also cover advanced features of Android Studio, such as App Links, Gradle build configuration, in-app billing, and submitting apps to the Google Play Developer Console. Assuming you already have some programming experience, are ready to download Android Studio and the Android SDK, have access to a Windows, Mac, or Linux system, and have ideas for some apps to develop, you are ready to get started.
