Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Adoption intention of halal traceability system among Agro-Food SMEs
Traceability system enables agro-food small and medium enterprises (SMEs) to record the information about attributes of their products along the supply chain effectively. However, a huge concern arises among consumers regarding a violation of halal food products. Halal traceability system affirms that halalness should be retained across the supply chain. The adoption of the system in which the level of complexity is the same as the traceability system is still low despite the high usage of computers and the internet by most SMEs in Malaysia. This study aimed to determine the adoption intention level of halal traceability system among agrofood SMEs. A preliminary study was conducted on randomly selected 26 agro-food SMEs. Responses from agro-food SMEs were obtained through semi-structured interviews using a structured questionnaire. The data were analysed using several statistical analyses such as descriptive analysis, mean ranking analysis, and Chi-square analysis. The results revealed that most agro-food SMEs involved in this study (15 companies, 57.7%), were categorized as a small-sized company. Further, based on the mean ranking analysis, the results showed that agro-food SMEs have a low adoption intention of halal traceability system (mean score of 3.91). The results ofChisquare analysis revealed that there was a significant association between the size of the company and the adoption intention of halal traceability system among agro-food SMEs (p=0.073). This study concludes that more exposure to recent advances to agro-food SMEs in Malaysia will improve their adoption intention of halal traceability system
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Effectiveness of ultrasound as a triage tool in ruling out fractures among non-critical emergency department patients
The popularity of ultrasound for acute diagnosis of fractures in the Emergency Department (ED) has increased over the recent years. This present study aimed to determine the sensitivity and specificity of ultrasound use for detection of fractures in a different environment, which is at the triage area of the ED. We compared the results of bedside ultrasound in detecting non-critical fractures to the current gold standard of X-rays in the triage area. The design was a single centered crosssectional study. From August 2014 till November 2014, a total of 46 patients were recruited, creating 75 image pairs. Following consent, a bedside ultrasound was performed and subsequently compared with X-ray reporting regarding the presence or absence of fractures. SPSS analysis was used to determine the sensitivity and specificity of ultrasound in diagnosing fracture as compared to X-rays. Ultrasound had a sensitivity of 72% (95% CI, 50.6% - 87.9%) and a specificity of 80% (95%CI: 66.3 - 90%) when compared to X-rays in fracture diagnosis. The kappa analyses showed moderate inter observer agreement (0.5) between ultrasound and X-rays in diagnosing fractures. This study suggests that the use of ultrasound as a triage tool yet has unacceptable sensitivity and needs further evaluation and consideration
Adverse drug reaction with midazolam use in emergency department
Midazolam is one of the most commonly used drugs for sedation in Emergency
Department (ED). This was a retrospective study conducted on 380 patients from December 2012 to May 2014 in ED of Universiti Kebangsaan Malaysia Medical
Centre (UKMMC). The objective was to elicit the frequency of side effects and
correlation to various factors i.e. socio-demography, co-morbidities, age groups
and underlying illnesses. Out of 380 patients, 35 patients experienced side effects
(20 patients with midazolam alone, 15 patients with combination of drugs). The
average age was 42 years and the average dose of midazolam was 3.5mg. The
most common other drug combined was fentanyl. The overall complication rate
for midazolam was 5.3%. The most common side effect recorded was excessive
somnolence (1.6%). Other side effects included local skin reactions (1.1%), vomiting
(0.8%), headache (0.8%) and hypotension (0.5%). There was no significant
association between the socio-demographic factors and drugs combination with
the side effects of midazolam on patients. It was concluded that midazolam was a
safe drug due to absence of any life-threatening side effects. There are possibilities
that most side effects recorded could be caused by other comfounding factors e.g.
underlying injuries or disease and combination with other drugs
Factors associated with emergency department revisits and hospitalization following discharged acute asthma exarcerbation
The objectives were to identify factors associated with early revisit of adult patients
with acute asthma exarcebation discharged from the Emergency Department (ED).
It was a retrospective cohort study with patients aged 12 years or more within a
period of 1 month and who were treated for acute asthma and discharged from the
ED of Sarawak General Hospital. A total of 397 patients fulfilled sampling criteria
and out of this number, 13.9% had revisit to the ED within 2 weeks. In all of these
revisit cases, 9.1% were actually admitted. Prescription rate of oral corticosteroid
was found to be low (24.9%) and abscond rate was high (25.1%). Patients who
absconded from the ED and their concurrent infection were associated with early
ED revisit
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
