With an aging global population, the number of dementia cases is growing exponentially. To address the upcoming dementia crisis, the World Health Organization and Alzheimer's Disease International (2012) collaborated on an extensive report, Dementia: A Public Health Priority. In the United Kingdom, Prime Minster David Cameron initiated a national challenge on dementia, forming 3 dementia challenge champion groups aimed at improving health and care, creating dementia-friendly communities, and promoting dementia research. In the U.S., President Obama signed the National Alzheimer's Project Act, which led to the formation of the Advisory Council on Alzheimer's Research, Care, and Services and the launch of the first National Plan to Address Alzheimer's Disease. The term "dementia capable" was introduced in the 2012 Recommendations of the Public Members of the Advisory Council and has since been adopted in both the recommendations and annual updates of the national plan. This paper will first compare and contrast government usage of the concepts dementia friendly and dementia capable, along with another valuable concept, dementia positive, that was added after reviewing the literature. Finally, a new vision statement for the U.S.' national plan will be proposed and recommendations incorporating these 3 concepts in policy, research, and practice will be made.

Study Objectives: Mobile health (mHealth) tools such as smartphone applications (apps) have potential to support sleep self-management. The objective of this review was to identify the status of available consumer mHealth apps targeted toward supporting sleep self-management and assess their functionalities. Methods: We searched four mobile app stores (iTunes Appstore, Android Google Play, Amazon Appstore, and Microsoft Appstore) using the terms "sleep", "sleep management," "sleep monitoring," and "sleep tracking." Apps were evaluated using the Mobile Application Rating Scale (MARS) and the IMS Institute for Healthcare Informatics functionality scores. Results: We identified 2,431 potentially relevant apps, of which 73 met inclusion criteria. Most apps were excluded because they were unrelated to sleep selfmanagement, simply provided alarm service, or solely played relaxation sounds in an attempt to improve sleep. The median overall MARS score was 3.1 out of 5, and more than half of apps (42/73, 58%) had a minimum acceptability score of 3.0. The apps had on average 7 functions based on the IMS functionality criteria (range 2 to 11). A record function was present in all apps but only eight had the function to intervene. About half of the apps (33/73, 45%) collected data automatically using embedded sensors, 27 apps allowed the user to manually enter sleep data, and 14 apps supported both types of data recording. Conclusions:The findings suggest that few apps meet prespecified criteria for quality, content, and functionality for sleep self-management. Despite the rapid evolution of sleep self-management apps, lack of validation studies is a significant concern that limits the clinical value of these apps.

Purpose of review This review discusses the concept of ‘dementia-friendly communities’ and summarizes the latest research and practice around such communities. This review also highlights important topic areas to be considered to promote dementia friendliness in healthcare settings. Recent findings Definitions of ‘dementia-friendly communities’ reflect the contemporary thinking of living with dementia (e.g., dementia as a disability, equal human rights, a sense of meaning). Existing research has covered a wide range of topic areas relevant to ‘dementia-friendly communities’. However, these studies remain qualitative and exploratory by nature and do not evaluate how dementia-friendly communities impact health and quality of life of people living with dementia and their caregivers. In healthcare settings, being dementia friendly can mean the inclusion of people with dementia in treatment discussion and decision-making, as well as the provision of first, adequate and appropriate service to people with dementia at an equivalent standard of any patient, second, person-centered care, and third, a physical environment following dementia-friendly design guidelines. Summary Research incorporating more robust study designs to evaluate dementia-friendly communities is needed. Being dementia-friendly in healthcare settings requires improvement in multiple areas – some may be achieved by environmental modifications while others may be improved by staff education.

In this study, we examine introductory physics students’ ability to perform analogical reasoning between two isomorphic problems which employ the same underlying physics principles but have different surface features. Three hundred sixty-two students from a calculus-based and an algebra-based introductory physics course were given a quiz in the recitation in which they had to first learn from a solved problem provided and take advantage of what they learned from it to solve another problem (which we call the quiz problem) which was isomorphic. Previous research suggests that the multiple-concept quiz problem is challenging for introductory students. Students in different recitation classes received different interventions in order to help them discern and exploit the underlying similarities of the isomorphic solved and quiz problems. We also conducted think-aloud interviews with four introductory students in order to understand in depth the difficulties they had and explore strategies to provide better scaffolding. We found that most students were able to learn from the solved problem to some extent with the scaffolding provided and invoke the relevant principles in the quiz problem. However, they were not necessarily able to apply the principles correctly. Research suggests that more scaffolding is needed to help students in applying these principles appropriately. We outline a few possible strategies for future investigation

We discuss the categorization of 20 quantum mechanics problems by physics professors and undergraduate students from two honors-level quantum mechanics courses. Professors and students were asked to categorize the problems based upon similarity of solution. We also had individual discussions with professors who categorized the problems. Faculty members' categorizations were overall rated higher than those of students by three faculty members who evaluated all of the categorizations. The categories created by faculty members were more diverse compared to the categories they created for a set of introductory mechanics problems. Some faculty members noted that the categorization of introductory physics problems often involves identifying fundamental principles relevant for the problem, whereas in upper-level undergraduate quantum mechanics problems, it mainly involves identifying concepts and procedures required to solve the problem. Moreover, physics faculty members who evaluated others' categorizations expressed that the task was very challenging and they sometimes found another person's categorization to be better than their own. They also rated some concrete categories such as "hydrogen atom" or "simple harmonic oscillator" higher than other concrete categories such as "infinite square well" or "free particle".
