Citation counts for peer-reviewed articles and the impact factor of journals have long been indicators of article importance or quality. In the Web 2.0 era, growing numbers of scholars are using ...scholarly social network tools to communicate scientific ideas with colleagues, thereby making traditional indicators less sufficient, immediate, and comprehensive. In these new situations, the altmetric indicators offer alternative measures that reflect the multidimensional nature of scholarly impact in an immediate, open, and individualized way. In this direction of research, some studies have demonstrated the correlation between altmetrics and traditional metrics with different samples. However, up to now, there has been relatively little research done on the dimension and interaction structure of altmetrics.
Our goal was to reveal the number of dimensions that altmetric indicators should be divided into and the structure in which altmetric indicators interact with each other.
Because an article-level metrics dataset is collected from scholarly social media and open access platforms, it is one of the most robust samples available to study altmetric indicators. Therefore, we downloaded a large dataset containing activity data in 20 types of metrics present in 33,128 academic articles from the application programming interface website. First, we analyzed the correlation among altmetric indicators using Spearman rank correlation. Second, we visualized the multiple correlation coefficient matrixes with graduated colors. Third, inputting the correlation matrix, we drew an MDS diagram to demonstrate the dimension for altmetric indicators. For correlation structure, we used a social network map to represent the social relationships and the strength of relations.
We found that the distribution of altmetric indicators is significantly non-normal and positively skewed. The distribution of downloads and page views follows the Pareto law. Moreover, we found that the Spearman coefficients from 91.58% of the pairs of variables indicate statistical significance at the .01 level. The non-metric MDS map divided the 20 altmetric indicators into three clusters: traditional metrics, active altmetrics, and inactive altmetrics. The social network diagram showed two subgroups that are tied to each other but not to other groups, thus indicating an intersection between altmetrics and traditional metric indicators.
Altmetrics complement, and most correlate significantly with, traditional measures. Therefore, in future evaluations of the social impact of articles, we should consider not only traditional metrics but also active altmetrics. There may also be a transfer phenomenon for the social impact of academic articles. The impact transfer path has transfer, or intermediate, stations that transport and accelerate article social impact from active altmetrics to traditional metrics and vice versa. This discovery will be helpful to explain the impact transfer mechanism of articles in the Web 2.0 era. Hence, altmetrics are in fact superior to traditional filters for assessing scholarly impact in multiple dimensions and in terms of social structure.
Background and aim
The advent of academic social networking tools (ASNTs) has brought a paradigm shift to academic culture and practice dynamics; however, there is an apparent dearth of information ...on its adoption among health professions academics in developing countries. This study aimed to assess knowledge, use, and perceptions of ASNTs among physiotherapy educators in Nigeria.
Methods
This cross-sectional study involved 20 consented physiotherapy educators from five universities in South-west Nigeria offering physiotherapy degrees. A self-administered questionnaire with adequate face and content validity was employed to assess knowledge, perception, barriers, and use of ASNTs. Descriptive statistics of frequency and percentages were applied.
Results
A majority of the respondents had knowledge and utilized ASNTs such as Research Gate (80%), Google Scholar (80%), Google Plus (70%), LinkedIn (50%), and Academia.edu (50%). Mynetresearch (5%) and Lameresearch (5%) were not popular, while Llaslo.com, Quarzy, and Myscience.ch were not known. ASNTs were used to raise personal profiles in the research community (100%), publicize research (95%), share authorized content (85%), attract funds (65%), attract future employers (65%), and actively discuss research and discover job opportunities (45%). Electricity failure (70%), lack of infrastructural facilities (70%), unavailability of internet facilities (60%), lack of technical knowhow (45%), time constraints (45%), and personal factors (45%) were the significant barriers in utilizing ASNTs.
Conclusion
Nigerian physiotherapy educators were knowledgeable and adopted most ASNTs. Power failure, lack of technical know-how, infrastructural and internet facilities, and personal factors limit the utilization of ASNTs among Nigerian physiotherapy educators.
Purpose - Advances in information technology (IT) have resulted in the development of various computer-mediated communication (CMC) and social networking tools. However, quantifying the benefits of ...utilizing these tools in the organizational context remains a challenge. In this study, the authors aim to investigate the effects of three specific tools, viz. instant messenger, email and knowledge forum, on facilitating the communication and social network at work, and their subsequent influence on individuals' work performance. Together with a social network diagram, the proposed model is validated by a survey of 59 employees of a company which embeds these three CMC and social networking tools in the work process. The key findings, implications and future research are discussed.Design methodology approach - The authors verify the research model with data from the Hong Kong office of an international bank headquartered in London, UK. They also collected the data on the social networks of 59 employees to draw a network diagram of the respondents using the social network analysis software UCINET.Findings - The research model is fully supported by the survey data. Meanwhile, the social networks analysis also suggests the linkage of using IM at work and the high level of degree and high level of closeness.Originality value - This study provided an empirical verification of media performance theories, evidenced by interactive tools such as IM and email. This research also directly linked the elements of social network, viz. degree, closeness and betweenness, with the CMC and social network tools, the communication, interactivity, relationship, and work performance.
Librarians at the Mayo Clinic developed customized Web 2.0 courses for library staff, health science faculty, and nurse educators. As demand for this type of training spread across the institution, a ...single, self-paced class was developed for all employees. The content covered the typical Web 2.0 and social media tools (e.g., blogs, really simple syndication RSS, wikis, social networking tools) emphasizing the organization's social media guidelines. The team consulted with the public affairs department to develop the class and coordinate marketing and advertising. The eight-module, blog-based course was introduced to all employees in 2010. Employees completing each module and passing a brief assessment receive credit on their employee transcript. Libraries staff provided support to participants throughout the duration of the course through chat widgets, e-mail, and blog comments. The results show that even though a high number of learners accessed the course, the completion percentage was low since there was no requirement to complete the course. Deploying a single, self-paced course for a large institution is an enormous undertaking, requiring the support of high level administration, managers, and employees.

User centered design is a relatively young design approach. Over the years, user centered design changed its scope. However, the concept of usability does not just expand by broadening the view on ...ease of use and learning. Experience is added in the nineties and in 2006 we find Apple suggest its iPod users to “Enjoy Uncertainty.” The history of user centered design (or human-computer interaction, or cognitive ergonomics) shows the development of the design approach as a movement in different dimensions:
from the reign of functionality to attention to individual users in context;
from user control to experience and entertainment; and
from a culturally defined cost-benefit goal to perspective on a multitude of design cultures and cultures of use.
