Cultural Self-Efficacy of Graduating Baccalaureate Nursing Students in a State Funded University in the Silicon Valley
The purpose of the study was to examine the level of cultural self-efficacy of graduating baccalaureate nursing students, who care for diverse populations, in a state funded university in the Silicon Valley, California. The level of cultural self-efficacy was measured using Bernal and Froman\u27s Cultural Self-Efficacy Scale (CSES). A convenience sample of 48 nursing students completed an 8-item demographic questionnaire and a 26-item CSES. The subjects of this study were found to have an increased level of cultural confidence in comparison with previous studies. This study suggests nurse educators continue to incorporate cultural concepts and skills in the nursing curriculum
Remarks on the Cryptographic Primitive of Attribute-based Encryption
Attribute-based encryption (ABE) which allows users to encrypt and decrypt
messages based on user attributes is a type of one-to-many encryption. Unlike
the conventional one-to-one encryption which has no intention to exclude any
partners of the intended receiver from obtaining the plaintext, an ABE system
tries to exclude some unintended recipients from obtaining the plaintext
whether they are partners of some intended recipients. We remark that this
requirement for ABE is very hard to meet. An ABE system cannot truly exclude
some unintended recipients from decryption because some users can exchange
their decryption keys in order to maximize their own interests. The flaw
discounts the importance of the cryptographic primitive.Comment: 9 pages, 4 figure
A Note on the Bellare-Rivest Protocol for Translucent Cryptography
We remark that the Bellare-Rivest protocol for translucent cryptography [J.
Cryptology (1999) 12: 117-139] can not truly enable the government to decrypt
partial encrypted communications
