The concept of treatment alliance in psychiatry has its origins in psychotherapy, but has also been influenced by several other constructs such as patientcentred care(PCC) and shared decision-making(SDM). Similarly, there has been a shift in conceptualization of treatment-adherence in psychiatric disorders including bipolar disorder(BD) from illness-centred and clinician-centred approaches to patient-centred ones. Moreover, the traditional compliance based models are being replaced by those based on concordance between clinicians and patients. Newer theories of adherence in BD place considerable emphasis on patient related factors and the clinician patient alliance is considered to be one of the principal determinants of treatment-adherence in BD. Likewise, current notions of treatment alliance in BD also stress the importance of equal and collaborative relationships, sensitivity to patients' viewpoints, sharing of knowledge, and mutual responsibility and agreement regarding decisions related to treatment. Accumulated evidence from quantitative research, descriptive accounts, qualitative studies and trials of psychosocial interventions indicates that efficacious treatment alliances have a positive influence on adherence in BD. Then again, research on the alliance-adherence link in BD lags behind the existing literature on the subject in other medical and psychiatric conditions in terms of the size and quality of the evidence, the consistency of its findings and clarity about underlying processes mediating this link. Nevertheless, the elements of an effective alliance which could have a positive impact on adherence in BD are reasonably clear and include PCC, collaborative relationships, SDM, open communication, trust, support, and stability and continuity of the relationship. Therefore, clinicians involved in the care of BD would do well to follow these principles and improve their interpersonal and communication skills in order to build productive alliances with their patients. This could go a long way in confronting the ubiquitous problem of nonadherence in BD. The role of future research in firmly establishing the alliance-adherence connection and uncovering the processes underlying this association will also be vital in devising effective ways to manage nonadherence in BD.展开更多

This paper proposes an Alliance-Authentication protocol among Hybrid Clouds that include multiple private clouds and/or public clouds. Mutual authentication protocol among entities in the Intra-Cloud and Inter-Cloud is proposed. Blind signature and bilinear mapping of automorphism groups are adopted to achieve the Inter-Cloud Alliance-Authentication, which overcome the complexity of certificate transmission and the problem of communication bottlenecks that happen in traditional certificate-based scheme. Blind key, instead of private key, is adopted for register, which avoids the unauthorized Key Management Center (KMC) faking the members to access the resources in traditional identity-based scheme. Compared with the traditional scheme, our scheme can also achieve anonymity, traceability and privacy protection. Extensive security and performance analysis show that the proposed schemes have an advantage in security, computation consumption and communication consumption.展开更多
