Building Relationship between Education Institutions and Students: Student Loyalty in Self-Financed Tertiary Education
WONG Shun Mun Helen,WONG Kin Ho
IBIMA Business Review , 2011,
Abstract: This study attempts to test the applicability of relationship marketing concepts within the self-financed tertiary education (SFTE) industry. Building on the well-established relationship marketing concepts, a conceptual model is proposed in this study to investigate the casual relationship between relationship commitment and student loyalty, and the key determinants of relationship commitment (relationship benefits, relationship termination costs, shared values, and trust). To achieve the above objectives, an in-depth study was conducted in a leading SFTE institution in Hong Kong. Structured questionnaires were used to collect data. Structural equation modeling approach was used to evaluate the explanatory power and casual links of the model. The results indicate that relationship commitment is a strong driver of student loyalty. Second, relationship benefits, relationship termination costs, and shared values are found to have positive influence on relationship commitment. Among these three determinants, the construct of relationship benefits is found to be the most important factor affecting relationship commitment. Third, trust is found to have no significant impact on relationship commitment in SFTE environment. The research findings provide new and useful insights to the management of SFTE in building relationship with students and resources allocation. The study discusses the implications of these findings and suggests areas for future research.

International Breastfeeding Journal , 2007, DOI: 10.1186/1746-4358-2-12
Abstract: Peer counsellors (PCs) were mothers who had successfully breastfed and had received formal training. Following a postnatal visit, they provided scheduled telephone consultations (Days 1, 4, 7, Weeks 2, 4, 8, and Month 4) to PC group mothers (n = 100) who continued breastfeeding their infants after discharge. Control group mothers (n = 100) received routine care.After adjusting for mothers' previous breastfeeding experiences, mothers' working status and breastfeeding problems, no statistical differences in mothers' feeding methods (exclusive, almost exclusive or predominant breastfeeding) were noted at the three follow-up times for intervention and control mothers respectively (Day 5: 37%/38%, 46%/53%, 57%/63%; Month 3: 10%/9%, 17%/23%, 20%/26%; Month 6: 2%/1%, 18%/18%, 18%/19%). All differences between the groups were not significant. Also, there was no evidence to suggest that PC intervention prolonged breastfeeding duration.The lack of effect of our PC intervention may reflect the low baseline breastfeeding rate and low value placed on breastfeeding in our population, the type of PC intervention or group allocation biases.ISRCTN93605280.At the fifty-fifth World Health Assembly, the World Health Organization (WHO) recommended that optimal infant nutrition was exclusive breastfeeding for the first six months of life, followed by the introduction of nutritionally adequate and safe complementary feeding with continued breastfeeding for up to the age of two years or beyond [1]. Despite the many advantages of breastfeeding, the majority of Hong Kong mothers do not attain this goal. Hong Kong's breastfeeding initiation rate, exclusive breastfeeding rate and overall breastfeeding duration are low compared to other countries [2]. Over a ten year period (1987 to 1997), rates of breastfeeding for more than three months increased from 3.9% to 10.3% [2]. Based on data from maternity units, the percentage of newborns ever breastfed in Hong Kong rose from a level of 10% in 1981

Abstract: In Hong Kong, community pharmacists work independently from medical doctors who often prescribe and dispense medications in a clinical setting. On the other hand, patients often seek first line treatment from community pharmacists [1]. Community pharmacists have long been an underutilized part of the human resources in primary care [2,3] as a result of the interplay between demand, supply and organization factors [4]. In Hong Kong, the use of over-the-counter (OTC) medications is popular in the local population. Previous studies found that 65% of the respondents used OTC medications [5] and that 32.9% of outpatients had taken OTC two weeks prior to their visits [6]. The majority of community pharmacists in Hong Kong admitted that they were most frequently asked about OTC [7].Chinese OTC medications are used as often as their western medicine counterparts in Hong Kong [8]. Unlike pharmacists, tertiary education is not a prerequisite for retailing Chinese medicine OTC [9]. Historically, Chinese medicine retailers worked alongside with Chinese medicine practitioners [10]. Since 1997, Chinese medicine practitioners as a medical profession have been recognized [11] and have become less dependent on Chinese medicine retailers.This article describes the behavioral patterns of both Chinese and western medical consultations and OTC use in a representative sample of the Hong Kong population. This information will provide timely input for planning pharmacists' and Chinese medicine retailers' future roles within the Hong Kong primary care system [12].Thematic Household Survey (THS) was conducted between November 2005 and March 2006 by the Census and Statistic Department (CSD), Hong Kong [13]. The THS covered the entire land-based population of Hong Kong and interviewed a total of 33,263 non-institutional individuals (response rate: 79.2%). The interviews were conducted in Cantonese. The sample represents a population of 6,750,652 persons of the general population.The questionna

Abstract: Here we report the crystal structure of a Class A β-lactamase PenP from Bacillus licheniformis 749/C with fluorescein conjugated at residue 166 after E166C mutation, both in apo form (PenP-E166Cf) and in covalent complex form with cefotaxime (PenP-E166Cf-cefotaxime), to illustrate its biosensing mechanism. In the apo structure the fluorescein molecule partially occupies the antibiotic binding site and is highly dynamic. In the PenP-E166Cf-cefatoxime complex structure the binding and subsequent acylation of cefotaxime to PenP displaces fluorescein from its original location to avoid steric clash. Such displacement causes the well-folded Ω-loop to become fully flexible and the conjugated fluorescein molecule to relocate to a more solvent exposed environment, hence enhancing its fluorescence emission. Furthermore, the fully flexible Ω-loop enables the narrow-spectrum PenP enzyme to bind cefotaxime in a mode that resembles the extended-spectrum β-lactamase.Our structural studies indicate the biosensing mechanism of a fluorescein-labelled β-lactamase. Such findings confirm our previous proposal based on molecular modelling and provide useful information for the rational design of β-lactamase-based biosensor to detect the wide spectrum of β-lactam antibiotics. The observation of increased Ω-loop flexibility upon conjugation of fluorophore may have the potential to serve as a screening tool for novel β-lactamase inhibitors that target the Ω-loop and not the active site.β-Lactamase is one of the major mechanisms of antibiotic resistance in bacteria. Enzymes of this family deactivate β-lactam antibiotics by hydrolyzing the conserved β-lactam moiety in the antibiotics and rendering them ineffective to bind to their target proteins, the penicillin-binding proteins (PBPs), which are essential for bacterial cell wall synthesis and survival [1,2]. Detailed mechanistic studies of these enzymes over the past decades have revealed a conserved mechanism of β-lactam hydrolysis that co
Negative Priming Under Rapid Serial Visual Presentation

PLOS ONE , 2012, DOI: 10.1371/journal.pone.0037023
Abstract: Negative priming (NP) was examined under a new paradigm wherein a target and distractors were temporally separated using rapid serial visual presentation (RSVP). The results from the two experiments revealed that (a) NP was robust under RSVP, such that the responses to a target were slower when the target served as a distractor in a previous trial than when it did not; (b) NP was found regardless of whether the distractors appeared before or after the targets; and (c) NP was stronger when the distractor was more distinctive. These findings are generally similar to those on NP in the spatial search task. The implications for the processes causing NP under RSVP are discussed in the current paper.
Challenges and Concerns of IT Outsourcing: A Case Study of an IT Department in a Public University Library
Ho Sow Kin
Asian Journal of Information Technology , 2012,
Abstract: Outsourcing has been viewed as a form of predetermined external provision with another enterprise for the delivery of goods and/or services that would previously have been offered in-house. Information Technology (IT) outsourcing encompasses all Business Process Outsourcing (BPO) that uses IT resources in various functions. It is a partnership with another company to handle all or some of the company s IT needs. In keeping pace with globalization and competitiveness in business environment, one cannot deny that outsourcing becomes a business strategy. Libraries store enormous and tremendous volumes of reading materials and archives and handles vast variety of users. IT outsourcing becomes an important strategy for any library concerned. Service providers are committed to provide libraries (service user) with the best available resources in computer systems, networking and application technologies. IT outsourcing enables libraries to improve service at a reduced cost. On the other hand, negative factors are inherent problems at the cost of outsourcing. This study attempts to present the findings of IT outsourcing from a case study of an IT department in a library. An interview with the head of the IT department of the library was conducted. Results suggest that the future of IT outsourcing in relation to the library is promising. Library reading materials and archives will be in digital form once the creation a digital library.
Link Availability Prediction for Cognitive Radio Ad Hoc Networks  [PDF]
Ling Hou, Kai-Hau Yeung, Kin-Yeung Wong
Journal of Computer and Communications (JCC) , 2014, DOI: 10.4236/jcc.2014.26003
Abstract:

One critical issue for routing in cognitive radio ad hoc networks (CRAHNs) is how to select a reliable path for forwarding traffic. This is because mobility may cause radio links to break frequently. The reliability of a path depends on the availability of those links that constitutes the path. In this letter, we present a novel approach to predict the probability of the availability of the link between two cognitive radio nodes. The prediction is achieved by estimating the link activation and spectrum activation probabilities. Our prediction is verified by simulation and proved to be accurate. This study can provide reliability assurance on dynamic routing for cognitive radio ad hoc networks.

Chemokine Regulation of Cell Trafficking in Lung Cancer Metastasis
Leena Gandhi,Kwok Kin Wong
Open Journal of Hematology , 2012,
Abstract: Chemokine regulation of cell trafficking has been identified as a critical pathway in metastatic progression. This review focuses on the role of the CXCR4-CXCL12-CXCR7 axis in regulating lung cancer invasion and metastasis. All of these factors have been identified as overexpressed in lung cancer specimens and in most cases are associated with poorer outcome. Preclinical studies have demonstrated an important role for CXCR4 in the steps of invasion, cell migration, and stromal cell adhesion and have suggested that CXCR4 is associated with “stem-like” cells that may be critical for initiating metastases. These data, together with emerging preclinical data on the efficacy of CXCR4 inhibitors suggests that CXCR4 should be explored as a clinical target for blocking metastatic progression in lung cancer.
Calibration of an Articulated Camera System with Scale Factor Estimation
Junzhou Chen,Kin Hong Wong
Computer Science , 2013,
Abstract: Multiple Camera Systems (MCS) have been widely used in many vision applications and attracted much attention recently. There are two principle types of MCS, one is the Rigid Multiple Camera System (RMCS); the other is the Articulated Camera System (ACS). In a RMCS, the relative poses (relative 3-D position and orientation) between the cameras are invariant. While, in an ACS, the cameras are articulated through movable joints, the relative pose between them may change. Therefore, through calibration of an ACS we want to find not only the relative poses between the cameras but also the positions of the joints in the ACS. In this paper, we developed calibration algorithms for the ACS using a simple constraint: the joint is fixed relative to the cameras connected with it during the transformations of the ACS. When the transformations of the cameras in an ACS can be estimated relative to the same coordinate system, the positions of the joints in the ACS can be calculated by solving linear equations. However, in a non-overlapping view ACS, only the ego-transformations of the cameras and can be estimated. We proposed a two-steps method to deal with this problem. In both methods, the ACS is assumed to have performed general transformations in a static environment. The efficiency and robustness of the proposed methods are tested by simulation and real experiments. In the real experiment, the intrinsic and extrinsic parameters of the ACS are obtained simultaneously by our calibration procedure using the same image sequences, no extra data capturing step is required. The corresponding trajectory is recovered and illustrated using the calibration results of the ACS. Since the estimated translations of different cameras in an ACS may scaled by different scale factors, a scale factor estimation algorithm is also proposed. To our knowledge, we are the first to study the calibration of ACS.

Evidence-Based Complementary and Alternative Medicine , 2009, DOI: 10.1093/ecam/nem100
Abstract: Using an adjuvant-induced arthritis rat model, we investigated the effects of a lipid extract of Perna canaliculus (Lyprinol®) on pain. Radiological examinations, as well as levels of pro- and anti-inflammatory (AI) cytokines, were measured aiming to provide independent objective data to the pain controlling investigation. We confirmed the ability of Lyprinol® to control pain at the initial phase of its administration; with similar efficacy to that observed with Naproxen. The pain scores slowly increased again in the group of rats treated with Lyprinol® after day 9–14. The Naproxen-treated rats remained pain-free while treated. Both Naproxen and Lyprinol® decreased the levels of the pro-inflammatory cytokines TNF-α and IFN-γ, and increased that of IL-10. Extra-virgin olive oil was ineffective on cytokine secretion. Rats treated with Lyprinol® were apparently cured after 1 year. This study confirms the AI efficacy of this lipid extract of P. canaliculus, its initial analgesic effect, its perfect tolerance and its long-term healing properties.
