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.

Monitoring Fibrous Scaffold Guidance of Three-Dimensional Collagen Organisation Using Minimally-Invasive Second Harmonic Generation

<div><p>The biological and mechanical function of connective tissues is largely determined by controlled cellular alignment and therefore it seems appropriate that tissue-engineered constructs should be architecturally similar to the <i>in vivo</i> tissue targeted for repair or replacement. Collagen organisation dictates the tensile properties of most tissues and so monitoring the deposition of cell-secreted collagen as the construct develops is essential for understanding tissue formation. In this study, electrospun fibres with a random or high degree of orientation, mimicking two types of tissue architecture found in the body, were used to culture human fibroblasts for controlling cell alignment. The minimally-invasive technique of second harmonic generation was used with the aim of monitoring and profiling the deposition and organisation of collagen at different construct depths over time while construct mechanical properties were also determined over the culture period. It was seen that scaffold fibre organisation affected cell migration and orientation up to 21 days which in turn had an effect on collagen organisation. Collagen in random fibrous constructs was deposited in alternating configurations at different depths however a high degree of organisation was observed throughout aligned fibrous constructs orientated in the scaffold fibre direction. Three-dimensional second harmonic generation images showed that deposited collagen was more uniformly distributed in random constructs but aligned constructs were more organised and had higher intensities. The tensile properties of all constructs increased with increasing collagen deposition and were ultimately dictated by collagen organisation. This study highlights the importance of scaffold architecture for controlling the development of well-organised tissue engineered constructs and the usefulness of second harmonic generation imaging for monitoring collagen maturation in a minimally invasive manner.</p></div
