The purpose of this paper is to map the evidence provided on the review types, and explain the challenges faced by classification techniques in sentiment analysis (SA). The aim is to understand how traditional classification technique issues can be addressed through the adoption of improved methods.

A systematic review of literature was used to search published articles between 2002 and 2014 and identified 24 papers that discuss regular, comparative, and suggestive reviews and the related SA techniques. The authors formulated and applied specific inclusion and exclusion criteria in two distinct rounds to determine the most relevant studies for the research goal.

The review identified nine practices of review types, eight standard machine learning classification techniques and seven practices of concept learning Sentic computing techniques. This paper offers insights on promising concept-based approaches to SA, which leverage commonsense knowledge and linguistics for tasks such as polarity detection. The practical implications are also explained in this review.

The findings provide information for researchers and traders to consider in relation to a variety of techniques for SA such as Sentic computing and multiple opinion types such as suggestive opinions.

Previous literature review studies in the field of SA have used simple literature review to find the tasks and challenges in the field. In this study, a systematic literature review is conducted to find the more specific answers to the proposed research questions. This type of study has not been conducted in the field previously and so provides a novel contribution. Systematic reviews help to reduce implicit researcher bias. Through adoption of broad search strategies, predefined search strings and uniform inclusion and exclusion criteria, systematic reviews effectively force researchers to search for studies beyond their own subject areas and networks.

Organizational politicsExamines the role of politics in the internal promotion of information systems IS professionals. Most studies take a management perspective when looking at the skills required of employees. Takes an employee perspective. Taking a systems perspective has a number of benefits when examining career progression since the important factors are so interwoven and deal greatly with softer perceptions. A systems view relies on providing multiple representations of reality. The main difference from previous studies is the emphasis on career progression given to the role of politics by IS practitioners.

The purpose of this paper is to explore technology acceptance and use behavior of IS innovations by entrepreneurs. To measure the perception of IS innovations by entrepreneurs the authors review unified theory of acceptance and use of technology and the entrepreneurial potential model, empirically compare the two models, develop a new model that integrates elements from the two models, and then empirically validate the new model (technology adoption decision and use (TADU)) in a technology acceptance context.

The data used to test the hypothesis are collected from 1,200 entrepreneurs in Malaysia. The research model was analyzed using structural equation modeling.

The results indicate that perceived desirability and perceived feasibility have significant effects on entrepreneurs’ intention to adopt and use innovations. Propensity to use is an important factor that has a significant effect on individual behavior. The precipitating events that happen in the time lag between intention and behavior will disrupt entrepreneurs’ inertia and induce a change in their behavior, encouraging them to seek the best opportunity available.

Understanding the individual, technological, and environmental factors that significantly affect IT adoption behavior can support policy makers in providing guidance on the adoption and usage of IT innovations by entrepreneurs.

This study proposes a TADU model with six core determinants of intention and usage – perceived desirability, perceived feasibility, performance expectancy, effort expectancy, social influence and facilitating conditions and two new moderators, precipitating events and the propensity to act.

In a highly competitive globalised environment, the innovation behaviour of employees plays a key role in the economic viability and competitive advantage of organisations. In this context, developing the understanding of innovation work behaviour is important for the field of individual innovation and this is the focus of the study. The paper aims to discuss this issue.

Data were collected using a survey from 549 employees in organisations operating in four major business centres in South Africa.

On-the-job embeddedness was positively and significantly related to innovation behaviours by employees in organisations operating in diverse industries. Consistent with the view that small organisations have a “behavioural” innovation advantage over larger organisations, the size of the organisation moderated the positive relationship between on-the-job embeddedness and innovation behaviours. On-the-job embeddedness was more positively related to innovation behaviours in small organisations than in larger organisations.

Employees who are highly embedded in their jobs (but not necessarily their communities) are more likely to enact innovation behaviours than employees who are not similarly embedded. Human resource management professionals and line managers can potentially foster employee innovation behaviours through adopting strategies aimed at positively influencing the fit, links and sacrifice dimensions of on-the-job embeddedness.

The study contributes to theoretical and empirical expansion of job embeddedness (JE) by examining: how work and non-work forces that attach employees to their organisations influence their propensity to enact innovation behaviours; and how organisation size moderates the relationship between JE and innovation behaviours. The results will help managers who wish to foster innovation.

The purpose of this paper is to determine the social media (SM) tools that are the most prevalent for project management activities, ascertain the areas of project management that are most benefited by SM, elucidate enablers and inhibitors to adoption of SM and identify the implications for virtual teams.

A Delphi study was used to explore why and how SM is being utilized in projects. In total, 32 participants contributed to three rounds of Delphi study, comprising two rounds of questionnaire followed by confirmatory interviews. The vulnerabilities and difficulties associated with the use of SM were examined by qualitative interviews.

Information sharing SM tools, such as YouTube, Dropbox, SlideShare, flickr, CrowdStorm and Instagram, are the most advantageous to project management. However, the tools utilized differ at different stages of the project lifecycle. The major benefit of SM is that it enables project teams to communicate efficiently and positively affects virtual team dynamics. Adoption can be inhibited by the absence of infrastructure in rural areas and differing preferences for SM tools in global regions. There is also a perceived lack of maturity of policies and procedures to govern SM adoption and use.

The research was conducted based on the Project Management Body of Knowledge version 5 project management processes.

The findings will enable practitioners to select SM tools that are suitable for project activities and forewarn about potential shortfalls. The findings also facilitate a qualitative analysis of SM attributes and their effect on project management.

Project practitioners can use the findings to adopt SM for their project management.

This study extends the literature concerning the use of SM for project management, provides a foundation for future research and may present as a useful guide for the adoption of relevant SM tools.

Grounded on the technology-organization-environment (TOE) framework, the purpose of this paper is to develop a two-stage model of radio frequency identification (RFID) adoption in livestock businesses. RFID adoption is divided into two stages, acceptance and extension. It is argued that RFID adoption in livestock businesses is influenced by technological (interoperability, technology readiness), organizational (readiness, market scope), and environmental (competitive market pressure, data inconsistency) factors.

From a qualitative field study, along with the support of existing literature, the authors developed a research model, which was then validated with survey data of 318 livestock businesses in Australia. Data analysis used partial least squares structural equation modeling.

Empirical results showed that interoperability, organizational readiness, and competitive market pressure, and data inconsistency significantly influence acceptance of RFID technology in livestock businesses. In addition, the extended use of RFID is determined mainly by interoperability, technology readiness, organizational market scope, and data inconsistency. The results suggested differential effect of data inconsistency– it had a negative influence on RFID acceptance but a positive impact on the extent of its use.

This is one of the first studies to examine RFID adoption as a two-stage process. The theoretical basis was based on TOE framework and the factors were developed from a field study. The results of this study will provide insights for different livestock industry including technologists, farm managers, and market players.

There is an absence of research examining job embeddedness in SMEs. Results of job embeddedness studies may not apply to SMEs, because the process of managing a SME differs from that of the large firm. The purpose of this paper is to examine relationships between on-the-job embeddedness, as well as each of its sub-dimensions, and turnover intentions; and group cohesion, on-the-job embeddedness and turnover intentions.

Data were collected from 147 employees in SMEs located in Perth, Western Australia and 350 employees from SMEs operating in four business centres in South Africa. After invariance testing, data from the two countries were combined to increase statistical power of the analysis.

On-the-job embeddedness and each sub-dimension were negatively related to turnover intentions. Group cohesion was positively related to composite on-the-job embeddedness. Findings suggest that while group cohesion on its own does not reduce turnover intentions, it does contribute to development of on-the-job embeddedness that, in turn, reduces turnover intentions.

Future research should control for the effects of external influences on turnover intentions. Findings imply that managerial actions related to antecedents of group cohesion could foster the on-the-job embeddedness of employees.

This study is perhaps the first that tests the operation of on-the-job embeddedness in SMEs located in two countries. The conceptual arguments for links between each of the sub-dimensions of on-the-job embeddedness and turnover intentions are based on distinctive characteristics of SMEs and can serve as a theoretical foundation for future research on embeddedness in SMEs.

The article considers the relationship between effective knowledge creation, acquisition and management and the user interface. The need for and problems associated with knowledge management are discussed and a useful model for organisational learning development is proposed (IPRAM). The article makes a detailed consideration of interface issues in relation to knowledge management and their role in synergising the personal‐corporate knowledge nexus for organisational and economic benefit. Alternative customisable representations of intranets are presented with their implications discussed. Network models, metaphors and iconic interfaces all have their merits. Besides improving interface representations of the intranet researchers need to consider how conceptual and experiential knowledge can be captured in the intranet.
