Determinants of negative word-of-mouth communication using social networking sites

At present, as customers often turn to social media platforms to share their service experience, this study aims to examine the determinants of their negative word-of-mouth communication using social networking sites following a service failure. Although many studies have examined the electronic word-of-mouth communication, studies on negative word-of-mouth communication using social media platforms remain sparse. Building on the cognitive dissonance theory and social support theory, this study proposes and empirically examines the role of contextual, individual and social networking factors in determining the customers’ intentions to engage in negative word-of-mouth communication using social networking sites. Self-reported retrospective survey was used to obtain responses from 206 online shoppers. The results of the structural equation modelling showed that feeling of injustice, firm attribution, firm image, face concern, reappraisal, use intensity and tie strength are key antecedents of negative word-of-mouth communication. The findings provide valuable insights for managers in developing effective Webcare interventions for negative word-of-mouth communication on social networking sites

Relationship between Macroeconomics and Stock Market: Empirical Study in Malaysia

This paper attempt to investigate the relationship between macroeconomic variables and FTSE Bursa Malaysia KLCI, the samples are divided into 2 groups such as foreign macroeconomic variables and local macroeconomic variables, foreign macroeconomic variables consist of Gold Bullion LBM price and Dow Jones Index, meanwhile local macroeconomic variables consist of Consumer Price Index, Base Lending Rate, Exchange Rate.This study employs data from Jan 2000 to Dec 2013 which contains a monthly data set of 168 observations. There are 3 methodologies used in this study to investigate the relationship, the first test is Unit Root test which used to test the stationary of each variable, the results indicate that all the variables are stationary in first difference, this is important to use stationary variables because if the variables are not stationary, it might lead to spurious regression. The second methodology is Johansen & Juselius Co-integration test to investigate the long run relationship among these variables, the results show that the foreign macroeconomic variables and local macroeconomic variables have long run relationship with KLCI and significant. Next, this study will investigate the short run relationship between macroeconomic variables and KLCI, the results indicate that Gold, BLR and CPI can granger cause KLCI and significant at 1%, 5% significance level respectively

Analyzing key influences of tourists’ acceptance of online reviews in travel decisions

Purpose: This study aims to examine what influence travelers’ adoption of online reviews, and whether the online reviews will influence their travel planning decisions. Design/methodology/approach: Data was collected from 193 respondents from eWOM websites and analyzed using structural equation modeling. Findings: Our results revealed that eWOM has a significant influence on travel decisions. Furthermore, travelers were willing to adopt information from eWOM and this information was useful in their travel planning and decisions. Gender and time spent on online reviews were found to affect travel planning and decisions. Travelers also found that the reviews and issues raised in eWOM had credibility and were of good quality. Research limitations/implications: Our study was not able to incorporate all factors which may be relevant to this study and so further theoretical development may be necessary to develop the conceptual model. The sample size, while adequate, can be expanded further. Practical implications: Operators and administrators of eWOM can use these findings to develop more user-friendly interfaces so that more positive reviews and sales can be generated. Social implications: Our results showed that travelers who adopt the information in eWOM will, in turn, use eWOM in their travel planning. This confirms the importance of eWOM and travelers in general will translate their pre-travel decisions into actual travel planning. Originality/value: This research extended existing eWOM and information system adoption studies and focused on the travel planning context. This research validated the significant roles of eWOM argument quality and credibility in predicting the information usefulness of eWOM

PAL: Personal Assistant System Using Low-Cost Computer

Automatic Speech Recognition (ASR) describes the ability of a computer to capture, identify and recognize the variety of human speech. It has been applied in many technologies such as personal assistant systems. Unfortunately, many personal assistant systems has been built in a way that may not always be disability-friendly and this causes the affected users whom are blind, disabled, illiterates and those who have physical limitations unable to enjoy the benefits of operating a computer. Hence, PAL is introduced. PAL is a personal assistant system built using low-cost device called the Raspberry Pi and open source voice-controlled software called Jasper. The functionalities of PAL includes searching for information on the internet, check for unread emails, schedule events in the calendar, manage a to-do list and translate texts through voice commands. Apart from that, a friendly graphical user interface (GUI) is also designed to display the output of each of the functional modules. Lastly, a number of tests are conducted to evaluate the performance and accuracy of the functional modules, GUI output display as well as response rate of the system. These tests include GUI output display test, user acceptance testing, the Command Success Rate (CSR) and Word Error Rate (WER) tests as well as response rate test. With the development of this project, it is hoped that PAL will be able to provide users with the benefits of using a computer in a more convenient and cost efficient manner

Interventions for supporting parents' decisions about autopsy after stillbirth (Review)

Background: Stillbirth remains one of the least understood areas of infant death and accurate data on the causes of stillbirth are the cornerstone of stillbirth prevention. An autopsy examination remains the gold standard post-mortem investigation for stillbirth. However, decisions about post-mortem investigations, particularly autopsy are difficult. The purpose of this review is to examine the effectiveness of methods to help parents who have experienced a stillbirth decide whether to have post-mortem investigations, including whether to have an autopsy performed. Objectives: The primary objectives were a) to examine the effectiveness of interventions to support parents' decisions about autopsy consent after a stillbirth on outcomes for parents, and b) to determine autopsy rates. Secondary objectives were to identify issues related to the acceptability of any interventions to parents and the feasibility of their implementation. Search methods: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (29 October 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 10), MEDLINE (1966 to 24 July 2012) and EMBASE (1980 to 24 July 2012), Current Controlled Trials metaRegister (mRCT) (18 September 2012) and the WHO International Clinical Trials Registry Platform Search Portal (ICTRP) (18 September 2012). We also searched the websites of the Stillbirth and Neonatal Death Charity (SANDS) and International Stillbirth Alliance (ISA) (18 September 2012) and then subsequently searched the websites of all the ISA member organisations. Selection criteria: Randomised controlled trials (RCTs) of interventions designed specifically to support parents who have experienced a stillbirth make decisions about their options for post-mortem investigations including all investigations after stillbirth compared with usual care. Data collection and analysis: Two review authors independently screened citations against the selection criteria. Main results: No studies meeting the review inclusion criteria were identified. A search of 40 websites associated with supporting parents who experience stillbirth also found little reference to, or information about autopsy or other post-mortem examinations. Authors' conclusions: Support for parents making decisions about autopsy or other post-mortem examinations after stillbirth must rely on the ad hoc knowledge and experience of those involved at the time

A review of agro-potential waste as a constituent in railway sleepers

Historically, concrete was used exclusively for building construction. Concrete has recently found application in the railway business, notably in the construction of concrete railway sleepers. Concrete is made up of three primary ingredients: fine aggregates, coarse aggregates, and cement. To enhance the qualities of concrete, research was conducted on the possibility of substituting wastes from other industries for the ingredients of concrete. With agriculture being one of Malaysia's main industries, ranking third in terms of national economic activity, it demonstrated the potential for using agricultural wastes as ingredients of concrete manufacturing (fine aggregate, coarse aggregate, and cement). While the characteristics of agricultural waste-derived concrete have improved, research on their use as concrete railway sleepers remains uncommon. As such, this article will examine the feasibility of incorporating agricultural waste into concrete for the manufacturing of concrete railway sleepers

Revisiting the Marrow Metabolic Changes after Chemotherapy in Lymphoma: A Step towards Personalized Care

Purpose. The aims were to correlate individual marrow metabolic changes after chemotherapy with bone marrow biopsy (BMBx) for its potential value of personalized care in lymphoma. Methods. 26 patients (mean age, 58 ± 15 y; 13 female, 13 male) with follicular lymphoma or diffuse large B-cell lymphoma, referred to FDG-PET/CT imaging, who had BMBx from unilateral or bilateral iliac crest(s) before chemotherapy, were studied retrospectively. The maximal standardized uptake value (SUV) was measured from BMBx site over the same area on both initial staging and first available restaging FDG-PET/CT scan. Results. 35 BMBx sites in 26 patients were evaluated. 12 of 35 sites were BMBx positive with interval decrease in SUV in 11 of 12 sites (92%). The remaining 23 of 35 sites were BMBx negative with interval increase in SUV in 21 of 23 sites (91%). The correlation between SUV change over the BMBx site before and after chemotherapy and BMBx result was significant (P < 0.0001). Conclusions. This preliminary result demonstrates a strong correlation between marrow metabolic changes (as determined by FDG PET) after chemotherapy and bone marrow involvement proven by biopsy. This may provide a retrospective means of personalized management of marrow involvement in deciding whether to deliver more extended therapy or closer followup of lymphoma patients

Upregulated mRNA expression of desaturase and elongase, two enzymes involved in highly unsaturated fatty acids biosynthesis pathways during follicle maturation in zebrafish

<p>Abstract</p> <p>Background</p> <p>Although unsaturated fatty acids such as eicosapentaenoic acid (EPA, C20:5n-3), docosahexaenoic acid (DHA, C22:6n-3) and arachidonic acid (ARA, C20:4n-6), collectively known as the highly unsaturated fatty acids (HUFA), play pivotal roles in vertebrate reproduction, very little is known about their synthesis in the ovary. The zebrafish (Danio rerio) display capability to synthesize all three HUFA via pathways involving desaturation and elongation of two precursors, the linoleic acid (LA, C18:2n-6) and linolenic acid (LNA, C18:3n-3). As a prerequisite to gain full understanding on the importance and regulation of ovarian HUFA synthesis, we described here the mRNA expression pattern of two enzymes; desaturase (fadsd6) and elongase (elovl5), involved in HUFA biosynthesis pathway, in different zebrafish ovarian follicle stages. Concurrently, the fatty acid profile of each follicle stage was also analyzed.</p> <p>Methods</p> <p>mRNA levels of fadsd6 and elovl5 in different ovarian follicle stages were determined by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR) assays. For analysis of the ovarian follicular fatty acid composition, gas chromatography was used.</p> <p>Results</p> <p>Our results have shown that desaturase displayed significant upregulation in expression during the oocyte maturation stage. Expression of elongase was significantly highest in pre-vitellogenic follicles, followed by maturation stage. Fatty acid composition analysis of different ovarian follicle stages also showed that ARA level was significantly highest in pre-vitellogenic and matured follicles. DHA level was highest in both late vitellogenic and maturation stage.</p> <p>Conclusion</p> <p>Collectively, our findings seem to suggest the existence of a HUFA synthesis system, which could be responsible for the synthesis of HUFA to promote oocyte maturation and possibly ovulation processes. The many advantages of zebrafish as model system to understand folliculogenesis will be useful platform to further elucidate the regulatory and mechanism aspects of ovarian HUFA synthesis.</p
