The recurrence rate of chronic subdural hematoma in patient taking anti-platelet medications or anticoagulant with reversal regimen and early complication after discontinuation of medications

Oral-Poster Presentation IMeeting Theme: Degenerative Lumbar SpineBACKGROUND: Chronic subdural hematoma is commonly seen in elderly patients. At the same time it is very common to encounter elderly patients taking either anti-platelet medications or anticoagulants for cardiovascular or neurovascular diseases. We have practice to reverse the effects anti-platelet drugs and anti-coagulants in patients with chronic subdural hematoma by discontinuation of medications and platelet transfusion or FFP/vitamin K. This is to attempt to compare the recurrence rate in patients taking anti-platelet drugs or anti-coagulant and patients taking neither. Also the complications of discontinuation of these medications are also evaluated …published_or_final_versio

Information seeking behavior of police officers in Hong Kong: an exploratory study

Open URL - http://www.academic-conferences.org/pdfs/ICICKM10-Booklet.pdfThe information seeking behavior of a random sample of 40 Hong Kong Police Force (HKPF) officers was investigated from the perspectives of: information seeking behavior; type of searching undertaken; level of sophistication of searching; ability to retrieve required information, and use of the HKPF Library (HKPFL). Frameworks such as: the information seeking process (Chowdhury 2004); the information management cycle (Choo, 1998); and the Information seeking of professionals model (Leckie, Pettigrew & Sylvain 1996), were applied. Data gathering methods included: survey; interview; observation; and case study. Results indicate that the respondents are not, overall, effective information seekers. The respondents generally apply simple retrieval techniques despite perceiving them to be less effective than more advanced techniques. The respondents were often unable to effectively frame simple enquiries. A novice member was less effective and slower at retrieving information than an experienced member, suggesting that transfer of organizational members’ knowledge of information seeking to newer members could be valuable. The sampled HKPF members prefer using print materials to electronic materials or web pages, although these formats are also popular. 27 (67.5%) respondents visit the HKPFL two or less times per week, while 36 (90%) respondents visit the HKPFL website two or less times per week. Most respondents use the HKPFL for leisure rather than work related purposes, although this behavior is both position and department sensitive. Most respondents prefer to browse the collections on shelves and seek help from librarians instead of searching the library catalogue. Recommendations for improving HKPF members’ information skills include: information literacy instruction for new recruits; promoting the HKPFL as an information hub; providing guides for use; and further developing the HKPFL to match members’ information needs by improving collections.published_or_final_versionThe 7th International Conference on Intellectual Capital, Knowledge Management & Organisational Learning (ICICKM 2010), Hong Kong, China, 11-12 November 2010.

Evaluation of an indigenous early intervention model for Chinese persons with early dementia

ePoster Session 6: Strengthening the social and cultural wellbeing of individuals, families and communities – promoting resilience, empowerment, safety and respectConference Theme: Promoting Social and Economic Equality: Responses from Social Work and Social DevelopmentIntroduction: The World Health Organization considers Dementia as a public health priority. The ageing population logicaly implies a growing population in persons with Dementia. Tung Wah Group of Hospitals started the Circle of Care project in 209. Integrating the Chinese cultural concept of body and mind linkage, the organization developed an evidence-driven, culturaly sensitve and holistic intervention for persons with early Dementia. Aims: This study is to evaluate the efectivenes of this pilot care intervention. Methodology: The study adopted a quasi-experimental design. Al the older adults who joined the programme were invited to join the study as participants of the intervention group. Older adults with a compatible mental abilty recruited from a Day Care Centre in the same district were invited to join as participants of the comparison group. The participants in the intervention group were interviewed before the intervention (t0), right after the intervention (t1) and 3 months after the intervention (t2). Information was colected from the care-givers as wel. As for the participants in the comparison group, interviews were ofered at t0 and t2 only. Dependent variables include the cognitve abilty, physical abilty, quality of life and depresion of the older adults as wel as the perceived relationship betwen the older adults and the carers. Findings: Thirty-two older adults and 31 carers joined the intervention group with 2 older adults in the comparison group. The within group analysis of the intervention group showed statistical signifcant changes in the cognitve abilty, quality of life and depresed mod of the older adults. The betwen group analysis indicated diferences in expected direction. In particular, the changes in functional reach test, depresion and quality of life were with statistical signifcance. Conclusion: The pilot study shows that he intervention is efective.published_or_final_versio

Do persons with intelectual disabilties understand death?

Concurent Sesion: 11EConference Theme: Promoting Social and Economic Equality: Responses from Social Work and Social DevelopmentBackground: With the longer lifespan of the persons with Intelectual Disabilties (PWID), they have a higher chance of outliving their parents. The los of parents among PWID is intricate because of the exceptionaly intimate parent-child relationship. Yet, PWID are often considered as incapable to understand the concept of death, thus do not have the abilty to grieve. Aim: The study is to explore PWID’s level of understanding of death. Methodology: Persons with mild to moderate level of ID, who are service users of the Rehabiltation services of Tung Wah Group Hospitals, are the participants in this study. A stratifed random sampling aproach is adopted. Data were colected through an in-depth interview, guided by a standardized protocol. In particular, one of thre vignetes describing death-related incidents was used to ases the understanding of five dimensions of death: causality, inevitabilty, finality, non-functionality, and universality. Self-care abilty, bereavement experience and demographics were measured as wel. Findings: 104 participants joined the study, with 60 having had bereavement experiences. More than half of the participants showed a ful understanding towards the ireversibilty and non-functionality dimensions respectively. Around a third showed a ful understanding towards the universality and causality dimensions respectively. 31.7% of participants showed a ful understanding to the inevitabilty dimension. Gender and self-care abilty sems to have minimal efect in understanding the diferent dimension of conceptualization of death. Bereavement experiences were found to be corelated signifcantly with nearly al the dimensions (χ 2 ranged from 4.48 to 6.03, p < 0.05), except for ireversibilty. Conclusions: Though not al PWID can understand the concept of death, a signifcant group of participants, even asesed to be with moderate grade of intelectual disabilty, showed a ful understanding towards diferent dimensions of death conceptualization. It definitely refutes the hypothesis of persons with ID not understanding death.published_or_final_versio

Punctuated Equilibrium and the Information Disadvantage of Authoritarianism: Evidence from the People's Republic of China

According to the punctuated equilibrium thesis, government attention allocation alternates between long periods of stasis and dramatic spurts of disequilibrium because democratic institutions enable minority groups to obstruct change. This article presents a critical discrepancy in contemporary China, where punctuated instability is significantly more intense despite a lack of democratic institutions to empower minority obstructionism. Our empirical analysis further reveals that punctuated intensity goes even higher for Chinese regions facing fewer signs of social discontent. We attribute the intensification of punctuated dynamics to an information disadvantage arising from the lack of diverse, independent sources of information under authoritarianism. Our finding contributes to punctuated equilibrium theory by underlining the function of opposition groups not only as obstructionists but also as challengers to policy priorities. By marginalizing these challengers, authoritarian institutions confine attention to known problems, leading to serious delays in the discovery of and adjustment to emerging issues
