This article aims to encourage information specialists to consider chronic disposition and situational priming as avenues to enrich information science research. The author makes a case for conducting such investigations by articulating the potential contributions of advancing theoretical and practical understanding of information science in both physical and technological environments using these approaches. The author also offers a theoretical toolbox of conceptual underpinnings relevant to chronic disposition and situational priming to provide a general overview on how such investigations can be performed. It is hoped that the arguments and theoretical lenses put forth will inspire further research in the area. © The Author(s) 2015.

Neurons and synapses have long been the dominant focus of neuroscience, thus the pathophysiology of psychiatric disorders has come to be understood within the neuronal doctrine. However, the majority of cells in the brain are not neurons but glial cells including astrocytes, oligodendrocytes, and microglia. Traditionally, neuroscientists regarded glial functions as simply providing physical support and maintenance for neurons. Thus, in this limited role glia had been long ignored. Recently, glial functions have been gradually investigated, and increasing evidence has suggested that glial cells perform important roles in various brain functions. Digging up the glial functions and further understanding of these crucial cells, and the interaction between neurons and glia may shed new light on clarifying many unknown aspects including the mind-brain gap, and conscious-unconscious relationships. We briefly review the current situation of glial research in the field, and propose a novel translational research with a multi-dimensional model, combining various experimental approaches such as animal studies, in vitro & in vivo neuron-glia studies, a variety of human brain imaging investigations, and psychometric assessments. © 2013 Kato, Watabe and Kanba.

Purpose: The main purpose of this paper is to: identify the views of public sector employees towards the importance of Knowledge Sharing (KS); identify the barriers to KS; and identify initiatives that may encourage KS. Design/methodology/approach: The design employed in this research was mainly descriptive in nature. A survey-based methodology employing a research questionnaire was used to elicit the views of public sector employees towards KS. A total of 320 questionnaires were randomly distributed and 170 were successfully collected, giving a response rate of 60 percent. Findings: The results showed that the respondents were very positive in their views towards "importance of KS" and they also strongly felt that knowledge was a source of competitive advantage. However, they were of the view that the importance of knowledge sharing was not clearly communicated and many of them were not sure whether KS strategy existed in their department. The public sector employees also showed self-serving biases when it came to their willingness to share knowledge compared with their perception of their colleagues' willingness to share knowledge. Respondents perceived organizational barriers as being more critical compared with individual barriers. Main organizational barriers were lacking in IT systems and there was a lack of rewards and recognition. Lack of time, lack of interaction and lack of interpersonal skills were identified as the main individual barriers. The most favoured KS initiatives found in this study was use of e-mail systems; inter-agency activities and use of information and communication technology (ICT) followed by support from top management. Research limitations/implications: The study is confined to the public sector and thus it cannot be generalized to all organizations. The sample for this study is also limited to two public sector departments: ICU (Implementation Coordination Unit) and PWD (Public Works Department) and thus the views are strictly limited to these agencies. The findings from this study can be useful in enhancing public policy towards effective management and implementation of KS programs. Originality/value: Since there is limited research on KS in the public sector from developing and emerging nations such as Malaysia, this empirical contribution will further enhance the theoretical knowledge on KS in the public sector from a developing nation's perspective. Second, this is one of the few studies that examine views towards knowledge donating and knowledge receiving in the public sector. This area needs the utmost attention, since it was found in this study that employees' perceived knowledge-sharing willingness (donating) may differ from colleagues' perceived KS willingness (knowledge receiving). © Emerald Group Publishing Limited.

The purpose was to conduct an ergonomics improvement in the order selection process in a refrigerated dairy factory. The workers' task was to pick dairy products to fulfill orders. Plant walkthroughs, unstructured interviews, and direct observation methods were used to study the existing process and problems. Ergonomics intervention was made by introducing a wireless handheld scanning system. A field experiment was carried out to compare the conventional paper pick list with the new system. Results indicated that workers faced difficulty in the paper pick list system, that is, to grasp a clipboard, turn pages, and place marks while wearing thick gloves. The new system eliminated this problem, and because of its ergonomics visual and audio feedback properties and more efficient process, it increased productivity (by 8.4%) and workers' satisfaction, simplified tasks, improved work quality, and reduced delay in invoicing. Replicating the intervention, other process-based manufacturing companies may reap similar benefits. © 2012 Wiley Periodicals, Inc.

The revolutionary development of smartphone which offers compelling computing and storage capabilities has radically changed the digital lifestyles of users. The integration of Near Field Communication (NFC) into smartphone has further opened up opportunities for new applications and business models such as in industry for payment, electronic ticketing and access control systems. NFC and graphical password scheme are two imperative technologies that can be used to achieve secure and convenient access control system. One of the potential uses of such technologies is the integration of steganography graphical password scheme into NFC-enabled smartphone to transcend conventional digital key/tokens access control systems into a more secure and convenient environment. Smartphone users would have more freedom in customizing the security level and how they interact with the access control system. As such, this paper presents a secure two-factor authentication NFC smartphone access control system using digital key and the proposed Encrypted Steganography Graphical Password (ESGP). This paper also validates the user perception and behavioral intention to use NFC ESGP smartphone access control system through an experiment and user evaluation survey. Results indicated that users weigh security as a dominant attribute for their behavioral intention to use NFC ESGP smartphone access control system. Our findings offer a new insight for security scholars, mobile device service providers and expert systems to leverage on the two-factor authentication with the use of NFC-enabled smartphone. © 2013 Elsevier B.V.

The study aimed to improve ergonomics, i.e. to increase productivity, quality, and work satisfaction of operators working in a harsh environment (i.e. freezer storage facilities) through the use of an audio feedback system. The operators' job was to select ice-cream products from a distribution warehouse to fulfill customer orders. A field experiment was carried out to compare the conventional method (the use of paper pick list) and the new method (the use of an audio pick list system). The audio system included audio feedback which enabled the operator to verify the correct storage location before selecting product from its location. Results showed that the use of the audio system was more effective as productivity of picking task increased by 43%, quality improved through reduction of more than two-thirds picking errors, and work satisfaction increased as hand motions used in the paper pick list system with gloved hands were eliminated. The impact of this study suggests that harsh environments with similar work flows can be aided with an audio feedback system, weighing the costs and benefits of the system from the perspective of ergonomics, quality, and productivity. © 2010 Elsevier B.V.

The study identifies and prioritizes the crucial Web Usability Factors (WUFs) for websites from 36 industries. 400 respondents participated in the web evaluation and more than 12,000 data points were collected and analyzed using Multiple Linear Regression. Seven WUFs were tested, i. e. Use of Color and Font, Use of Graphics and Multimedia, Clarity of Goals in Website, Trustworthiness of Website, Interactivity of Website, Ease of Web Navigation, and Downloading Speed of Website. Results reveal that every industry has a different set of crucial WUFs. The research compared and discussed its results with previous studies such as Agarwal and Venkatesh (Inf. Syst. Res. 13:168-186, 2002). Moreover, students' preference for Web usability was compared with that of general Internet users. The study provides a simple method to measure web usability and to determine which WUFs are important for a specific industry with consideration of the users' role. Practitioners can use the results as a guide to design usable websites for specific industry. This study is the first that comprehensively examines the WUFs of students by employing a very large sample size across various industries, thus yielding more specific and meaningful results. © 2010 Springer Science+Business Media, LLC.

In the highly competitive food service industry, restaurateurs are continuously exploring ways to deliver customer value and increase consumers’ dining intentions during special occasions. Prior research has examined rational qualities, such as price, food quality, and service quality, but as more restaurateurs strategically capitalize on the significance of these factors, previously held competitive advantages are beginning to fade, calling for further investigation to uncover new factors and contemporary restaurant marketing strategies. This study attempts to fill the gap by examining constructs from a psychological perspective. In particular, this study investigates the influences of culture, value, self-enhancement, gratification, and subjective norms on consumers’ attitudes and restaurant dining intentions during special occasions. The results show that culture, value, self-enhancement, and gratification are positively related to attitude whereas attitude and subjective norms have positive effects on intention. The implications for theory and practice are discussed, limitations are acknowledged, and research directions are presented. © Taylor & Francis Group, LLC.

Prior lab experiment and simulated environment ergonomics studies revealed the cause-and-effect relationship between ergonomics and quality with high internal validity. However, the external validity, i.e. the generalisability of this relationship to field settings (manufacturing plants) cannot be ascertained unless field experiment studies are conducted. Therefore, the current study aims to review five field experiment ergonomics studies to strengthen the external validity of this relationship. The studies reviewed include Axelsson (2000. Quality and ergonomics: Towards successful integration. Thesis (PhD). Linkopink University) in an assembly plant, Gonzalez et al. (2003. Ergonomic performance and quality relationship: an empirical evidence case. International Journal of Industrial Ergonomics, 31 (1), 33-40) in metal manufacturing, Yeow and Sen (2003. Quality, productivity, occupational health and safety and cost effectiveness of ergonomic improvements in the test workstations of an electronic factory. International Journal of Industrial Ergonomics, 32 (3), 147-163; 2006. Productivity and quality improvements, revenue increment, and cost reduction in the manual component insertion lines through the application of ergonomics. International Journal of Industrial Ergonomics, 36 (4), 367-377) in printed circuit assembly factories, and Erdinc and Vayvay (2008b. Ergonomics interventions improve quality in manufacturing: a case study. International Journal of Industrial and Systems Engineering, 3 (6), 727-745) in a textile factory. The manufacturing tasks, ergonomics and quality methodologies, ergonomics problems, ergonomics interventions, and quality improvement outcomes were examined. The study found that ergonomics problems, particularly awkward postures, cause human error which results in quality defects. All studies show significant reduction in defects and three studies show financial gains, i.e. savings on rejection costs. This research provides researchers and engineers an insight into why ergonomics problems can lead to poor quality and how to assess such problems and apply ergonomics interventions for higher quality performance in manufacturing. © 2011 Taylor & Francis.

Olson argued that larger (smaller) organizations or groups are weaker (stronger) in terms of collective action performance and advances the idea that small groups exhibit better collective action performance. Olson also argued that a coercive centralized state is required to sustain collective action by an organization or group. A considerable body of scholarship has developed over the past half century to investigate these two insights. Scholarship, however, has not focused on his third insight: when a large organization is divided into federated groups, its collective action performance becomes efficient. In an analysis of Japan's large-scale, federated irrigation management experience, this study demonstrates that Olson's third insight is substantially relevant, but his argument regarding the necessity for a coercive centralized state requires further consideration. Furthermore, the study reveals that a large organization can generate stronger collective action as a federation of many groups; however, the state's involvement must be fundamentally non-coercive and non-participatory to facilitate user self-governance. © 2014 Elsevier Ltd.
