ABSTRACTNonprofit organizations (NPOs) are strategically using their own personal website to present themselves to the public and share information. Despite the potential benefits of enhanced public confidence and trust, reduced operating costs, improved donor decision making, and increased donations, many nonprofit organizations have resisted the adoption of web disclosure. Informed by the literature on information systems (IS) adoption and technological innovation, this study examines the primary factors that influence the adoption and resistance of web disclosure. Our sample consisted of 176 survey responses from an initial group of 3,323 U.S. NPOs. The statistical results indicate that attitude toward disclosure, compatibility of disclosure with current practices, and financial readiness have a positive influence on web disclosure adoption. The findings have implications for research and practice. 相似文献

Controlled tabular adjustment (CTA) is a relatively new protection technique for tabular data protection. CTA formulates a mixed integer linear programming problem, which is challenging for tables of moderate size. Even finding a feasible initial solution may be a challenging task for large instances. On the other hand, end users of tabular data protection techniques give priority to fast executions and are thus satisfied in practice with suboptimal solutions. This work has two goals. First, the fix-and-relax (FR) strategy is applied to obtain good feasible initial solutions to large CTA instances. FR is based on partitioning the set of binary variables into clusters to selectively explore a smaller branch-and-cut tree. Secondly, the FR solution is used as a warm start for a block coordinate descent (BCD) heuristic (approach named FR+BCD); BCD was confirmed to be a good option for large CTA instances in an earlier paper by the second and third co-authors (Comput Oper Res 2011;38:1826–35 [23]). We report extensive computational results on a set of real-world and synthetic CTA instances. FR is shown to be competitive compared to CPLEX branch-and-cut in terms of quickly finding either a feasible solution or a good upper bound. FR+BCD improved the quality of FR solutions for approximately 25% and 50% of the synthetic and real-world instances, respectively. FR or FR+BCD provided similar or better solutions in less CPU time than CPLEX for 73% of the difficult real-world instances. 相似文献

This paper uses a mixed-methods approach to examine the relation between online academic disclosure and academic performance. A multi-ethnic sample of college students (N = 261; male = 66; female = 195; M age ≈ 22 years) responded to open-ended questions about their Facebook use. Thematic analysis revealed that over 14% of the Facebook wall posts/status updates (N = 714) contained academic themes; positive states were more frequent than negative and neutral states and students with lower GPAs expressed negative states more often. A path analysis suggested that academic performance may determine college students’ Facebook use, rather than the reverse. Implications for student support services are discussed. 相似文献

Radio Frequency Identification (RFID)‐based parking management systems provide facilities to control parking lot systems within easy access and secure inspection. Chen and Chong have presented a scheme to prevent car thefts for parking lot management systems, which is based on EPC C1‐G2 RFID standard. They claimed that their protocol is resistant against well‐known RFID attacks. In this paper, we prove that Chen and Chong's scheme is not resistant against secret disclosure and impersonation attacks. Therefore, in Chen and Chong parking lot system, a car may be stolen without having a valid tag. In this paper, we also show that the proposed impersonation attack works for any length of cyclic redundancy check and the secret disclosure attack costs at most 216 evaluations of the used pseudo random number generator. The success probability of both attacks is 1 while their complexity is only 2 runs of the protocol. Finally, we present an improved protocol and formally and informally prove that the improved protocol provides the desired level of security and privacy. 相似文献

The disclosure of emotional events to various social intimates (disclosure targets) was measured in 2 samples (soldiers and first responders) at risk for posttraumatic stress disorder (PTSD), as well as a comparison sample of college students. These 3 groups completed survey measures of disclosure, and at risk groups also completed measures of PTSD symptoms and social support. Groups at risk for PTSD were less likely to disclose emotions related to potentially traumatic events than were college students reporting general emotional disclosure. Overall, disclosure of positive emotions was more likely than disclosure of negative emotions. Furthermore, amount of disclosure depended on the person to whom the individual disclosed. Within groups at risk for PTSD, social support was associated with lower levels of PTSD. However, this relationship was mediated by emotional disclosure to each target. Disclosure of positive emotions generally was associated with lower levels of PTSD, and disclosure of negative emotions to those with similar at-risk status was associated with greater levels of PTSD.

Research into youth mentoring suggests that programs focused on specific practices (e.g., emotional disclosure and collaborative relationships) increase the likelihood of a successful mentoring relationship, factors similar to the psychotherapy literature. However, research into psychotherapy with Asians has indicated that these factors, based on Western values, are less effective, especially with those who are less acculturated. To test the relevance of these factors within mentor-type relationships, this study examined the relationship between acculturation and distress disclosure, and the relationship between acculturation and the retrospective willingness to emotionally self-disclose to friends and unrelated, trusted adults in 98 participants representing several ethnic Asian backgrounds. Both values-based and behaviorally based acculturation measures were used. Values-based, but not behaviorally based acculturation, predicted distress disclosure (i.e., less acculturated individuals were less likely to disclose distress). Using an imagery protocol, participants were then asked to think back to adolescence and indicate their willingness to self-disclose emotions to friends and unrelated, trusted adults. Participants were more willing to self-disclose emotions to friends compared to unrelated, trusted adults, regardless of values acculturation level. However, a significant interaction occurred in an unanticipated direction using behaviorally based acculturation. Less behaviorally acculturated individuals were more willing to disclose emotions to unrelated, trusted adults compared to more behaviorally acculturated individuals. Discussion regarding the results revolved around the utility of a behavioral measure of acculturation, values and behaviors in acculturation, the role of older persons in Asian culture, and the possible role of community in the acculturation process.
