Understanding Internet Banking Adoption and Continue-Use Behavior: A Hong Kong Perspective
This study investigates adoption/continue-use behavior within the context of Hong Kong Internet Banking services. A research framework based on the extended Technology Acceptance Model (TAM2) and Social Cognitive Theory was developed to identify factors that would influence the adoption/continue-use of Internet Banking. Structural Equation Modeling (SEM) was employed to examine the entire pattern of inter-correlations among the eight proposed constructs, and to test related propositions empirically. The results reveal that both subjective norm and computer self-efficacy indirectly play significant roles in influencing the intention to adopt Internet Banking. Perceived ease of use has a significant indirect effect on intention to adopt/continue-use through perceived usefulness, while its direct effect on intention to adopt is not significant in this study
A data-mining approach for multiple structural alignment of proteins
Comparing the 3D structures of proteins is an important but computationally hard
problem in bioinformatics. In this paper, we propose studying the problem when
much less information or assumptions are available. We model the structural
alignment of proteins as a combinatorial problem. In the problem, each protein
is simply a set of points in the 3D space, without sequence order information,
and the objective is to discover all large enough alignments for any subset of
the input. We propose a data-mining approach for this problem. We first perform
geometric hashing of the structures such that points with similar locations in
the 3D space are hashed into the same bin in the hash table. The novelty is that
we consider each bin as a coincidence group and mine for frequent
patterns, which is a well-studied technique in data mining. We
observe that these frequent patterns are already potentially large alignments.
Then a simple heuristic is used to extend the alignments if possible. We
implemented the algorithm and tested it using real protein structures. The
results were compared with existing tools. They showed that the algorithm is
capable of finding conserved substructures that do not preserve sequence order,
especially those existing in protein interfaces. The algorithm can also identify
conserved substructures of functionally similar structures within a mixture with
dissimilar ones. The running time of the program was smaller or comparable to
that of the existing tools
A report on an evaluation of the HOPE, worldwide seniors day 2003
The HOPE worldwide 1 (HWW) in Hong Kong has been chartered as a charity organization since 1993 with its focus on organizing service programmes in China, Hong Kong and Taiwan. Amongst these, the Hope for Seniors Day is one of the many attempts initiated by the HWW to meet the urgent needs of the growing ageing population in Hong Kong. Starting from 1996, volunteers from corporations and social organizations have been recruited for the Hope for Seniors Day on an annual basis. The programme aims at giving practical assistance to elderly people who are living alone in public housing estates, as well as building up relationship between the volunteers and the elderly. The volunteers help clean and repaint the seniors\u27 homes. In the past 7 years, the programme has already served over 37,000 single elderly people and mobilized more than 15,000 volunteers to participate

C-Terminal Binding Protein 2 Is a Novel Tumor Suppressor Targeting the Myc-Irf4 axis in Multiple Myeloma
Multiple myeloma (MM) cells are addicted to MYC and its direct transactivation targets IRF4 for proliferation and survival. MYC and IRF4 are still considered undruggable, as most small-molecule inhibitors suffer from low potency, suboptimal pharmacokinetic properties, and undesirable off-target effects. Indirect inhibition of MYC/IRF4 emerges as a therapeutic vulnerability in MM. Here, we uncovered an unappreciated tumor-suppressive role of C-terminal binding protein 2 (CTBP2) in MM via strong inhibition of the MYC-IRF4 axis. In contrast to epithelial cancers, CTBP2 is frequently downregulated in MM, in association with shortened survival, hyperproliferative features, and adverse clinical outcomes. Restoration of CTBP2 exhibited potent antitumor effects against MM in vitro and in vivo, with marked repression of the MYC-IRF4 network genes. Mechanistically, CTBP2 impeded the transcription of MYC and IRF4 by histone H3 lysine 27 deacetylation (H3K27ac) and indirectly via activation of the MYC repressor IFIT3. In addition, activation of the interferon gene signature by CTBP2 suggested its concomitant immunomodulatory role in MM. Epigenetic studies have revealed the contribution of polycomb-mediated silencing and DNA methylation to CTBP2 inactivation in MM. Notably, inhibitors of Enhance of zeste homolog 2, histone deacetylase, and DNA methyltransferase, currently under evaluation in clinical trials, were effective in restoring CTBP2 expression in MM. Our findings indicated that the loss of CTBP2 plays an essential role in myelomagenesis and deciphers an additional mechanistic link to MYC-IRF4 dysregulation in MM. We envision that the identification of novel critical regulators will facilitate the development of selective and effective approaches for treating this MYC/IRF4-addicted malignancy
The effects of a mindfulness-based family psychoeducation intervention for the caregivers of young adults with first-episode psychosis: A randomized controlled trial
Objective: In this study, we investigated the effects of a mindfulness-based family psychoeducation (MBFPE) program on the mental-health outcomes of both caregivers and young adults with first-episode psychosis with an onset in the past three years through a multi-site randomized controlled trial. We also studied the outcomes of three potential mediating effects of interpersonal mindfulness, expressed emotions, and non-attachment on the program. Method: We randomly assigned 65 caregivers of young adults with psychosis to MBFPE (n = 33) or an ordinary family psychoeducation (FPE) program (n = 32); among them, 18 young adults in recovery also participated in the evaluation of outcomes. Results: Intent-to-treat analyses were conducted. No significant time × group interaction effects of MBFPE and FPE programs were found in any of the caregivers’ outcomes. However, the young adults with psychosis reported higher levels of recovery after the MBFPE program than after the ordinary FPE program (F = 8.268, p = 0.012, d = 1.484). They also reported a larger reduction in over-involvement of their caregivers (F = 4.846, p = 0.044, d = 1.136), showing that MBFPE had a superior effect to FPE in promoting recovery and reducing over-involvement. Conclusions: A brief psychoeducation program may not reduce the burden on or improve the mental-health outcome of caregivers of individuals with recent-onset psychosis. However, integrating mindfulness into a conventional family psychoeducation program may reduce the expressed emotions of caregivers, especially over-involvement. Further studies should explore how psychoeducation programs can reduce the impact of psychosis on family through sustainable effects in terms of reducing their burden and expressed emotions, using a rigorous study and adequate sample size
