Privacy-Preserving Electronic Ticket Scheme with Attribute-based Credentials

Electronic tickets (e-tickets) are electronic versions of paper tickets, which enable users to access intended services and improve services' efficiency. However, privacy may be a concern of e-ticket users. In this paper, a privacy-preserving electronic ticket scheme with attribute-based credentials is proposed to protect users' privacy and facilitate ticketing based on a user's attributes. Our proposed scheme makes the following contributions: (1) users can buy different tickets from ticket sellers without releasing their exact attributes; (2) two tickets of the same user cannot be linked; (3) a ticket cannot be transferred to another user; (4) a ticket cannot be double spent; (5) the security of the proposed scheme is formally proven and reduced to well known (q-strong Diffie-Hellman) complexity assumption; (6) the scheme has been implemented and its performance empirically evaluated. To the best of our knowledge, our privacy-preserving attribute-based e-ticket scheme is the first one providing these five features. Application areas of our scheme include event or transport tickets where users must convince ticket sellers that their attributes (e.g. age, profession, location) satisfy the ticket price policies to buy discounted tickets. More generally, our scheme can be used in any system where access to services is only dependent on a user's attributes (or entitlements) but not their identities.Comment: 18pages, 6 figures, 2 table

Dish it up! THE INFLUENCE OF KIND DININGTM& GREEN HOUSE MODEL FOOD AND FOOD SERVICE INNOVATIONS ON THE RESIDENT EXPERIENCE IN RESIDENTIAL CARE FACILITIES.

The purpose of this study is to understand how innovative practices affect the satisfaction elder-care facility residents have with their food-related life. The study looks through the lenses of food and food service activities, related medical care activities, and facility design. The Older Americans Act of 1965 defined the basic rights of elders in American society. The statement and objectives codified in that Act have provided the outline for eldercare in the community and in residential care facilities ever since. Legislative updates in 2017 more clearly identified “person-centered” care as the ideal in elderly care homes. Research using the diffusion of innovation theory was pursued in two nursing homes which participated in a naturalistic inquiry. Different innovative practices regarding the food-related life of each resident was the focus. Self-efficacy theory was used to better understand the perspective of the residents and their reactions and responses to the care they receive. Ethnographic research using observations, interviews and historical and current literature over an eight-month period examined the day-to-day lives of elders in these care homes, concentrating on elements related to the food and food systems. Results show that co-occurring innovations obscure the influence of single culture change components and also support components in ways that are not yet clearly understood. Nursing and food services staff training is lagging behind the person-centered culture change innovations related to food and food services activities

Threads in a Tapestry: An Ethnographic Evaluation of Milken Community High School’s Tiferet Fellowship Program

This study explored an essential question, What does the lived experience of students in the Tiferet program mean for them and others? By exploring the background, implementation, and lived-experiences of two academic-year sophomore cohorts from Milken Community High School in Los Angeles as they lived and participated in a semester study abroad program at the Alexander Muss Institute of Israel Education in Hod HaSharon, Israel, the study shows the impact-of that experience on the students in the program and the school culture at large. The study engaged in a description of the program’s development and evaluation of the lived-experiences as they were reported by students and parents through surveys and video interviews and observed by the researchers. By using a mixed-genre approach and a media-enhanced web site, this study created a sense of the experience of living in Israel for one semester of the sophomore year.

Walking to Mourning Doves: A Memoir

Preface: Waking to Mourning DovesWaking to the soulful call of a mourning dove shortly after my mother’s death gave me the inspiration for my book title. Their plaintive cooing evokes nostalgic reminders of my life growing up on rural South Dakota prairies in the 1940s and 1950s, a memory of the simpler times of my youth. Soft spring mornings, gentle breezes stirring the curtains and a cacophony of birdsong and farm animal sounds define contentment to me. Their cooing still evokes the same feeling that all is right with the world. Mourning doves are unassuming, not flashy and don’t push and shove or bully other birds out of their space. They have adapted to blend into their surroundings, just as the women who settled the Great Plains did. Their nests and homes aren’t fancy, but they have survived and thrived, just like my immigrant ancestral families. Furthermore, they symbolize much of the happenings of my life and the experiences that have molded it, for they are like the soft-spoken ladies that surrounded me in my childhood: women who helped form my character and outlook on the world. These ladies were strong women and full partners in life, but with the polite, gentle demeanor of mourning doves. My book is built around excerpts from my personal diary entries from ages ten to twenty-one, adult journaling and my memories. Dated diary entries and family journals are printed verbatim and expanded upon. It is obvious from this book that I have an interest in preserving family history. My husband and I have published seven family-history books that describe our ancestors as far back as we can find records. Many go back hundreds of years and dozens of generations to our northern European roots. In addition to the history of our ancestors, I wish to pass on to my descendants my own personal history. It is my hope that this memoir will inspire readers to record their own life experiences
