Abstract

Web traffic is doubling every year, according to recent global studies. The user needs more information from Web sites and wants to spend as little time for downloading as possible. Simultaneously, more Internet bandwidth is needed and all ISPs are trying to build high bandwidth networks. This paper presents a case study that calculates the reduction of the time needed for a Web page to be fully downloaded and delivered to the user. Presents a way to calculate the reduction of data transfer, bandwidth resources and response time when the HTTP/1.1’s compressing feature is enabled (either in plain hypertext files or the text output of CGI programs or dynamically generated pages). Measurements are taken from five popular Web sites in order to validate our statement for reduction in transfer time. The definition of the mean size of a Web page that commercial Web sites have is additionally in the scope of this paper.

Abstract

Aims to present the work done in the development of a simplified office suite for disabled and focus on the use of technology applied to the area of “designing for all”. The paper presents an overview of the state‐of‐the‐art in the design for all. It provides practical references to techniques used. The main scope of the paper is to explore the developed technology and give details for the adopted mechanisms. It provides information about designing and implementing software applications for disabled and present a case study for mentally disabled. The paper presents a system that can be used by a specific target group. For this reason, it should be used as reference point for this group, although several techniques can be used for other user categories. The paper is a very useful presentation of an actual system that has been designed and implemented to cover the needs of disabled, useful for interaction with designers and researchers in assistive technology, and it fulfils the need for demonstrative technology in the area of designing for all.

Abstract

Although waiting on the Internet is widely recognised as a crucial factor in the evolution of e‐commerce and the Internet in general, it is not a widespread topic of research. This article identifies and reviews 21 papers based on 13 separate empirical studies on waiting on the Internet. The literature draws from the areas of marketing, system response time studies and quality of service studies. Having reviewed the existing literature, this article proposes an agenda for future research. Recommendations are made to extend the range of research methodologies applied to this topic, to broaden the definition of waiting on the Internet to include other forms of online waiting, and to continue the interdisciplinary approach to research on online waiting.

The purpose of this paper is to explore farmers’ intentions to engage in food brand development schemes and identify the factors that impact this.

Abstract

Purpose

The purpose of this paper is to explore farmers’ intentions to engage in food brand development schemes and identify the factors that impact this.

Design/methodology/approach

By assuming the utility maximization behavior of farmers, based on data collected from 539 fruit and vegetable producers, this study estimates an intention to participate and a willingness to pay model.

Findings

Three groups of factors determine the utility the farmers derive and subsequently their engagement in brand development. Farm business characteristics include farmers’ age, the attainment of quality certification and cultivated area, while psychological factors include farmers’ attitudes toward local reflections of the brand, perceptions regarding the need for farm business external support and consumers’ interest, as well as farmers’ commitment to quality requirements. Farmers’ strategies related to the share of products sold by cooperatives and to individually use the brand also determine their engagement in a brand development scheme.

Research limitations/implications

Future research should distinguish producers according to the marketing channel they choose and their industry, and explore the intentions of intermediate marketers.

Practical implications

Marketing cooperatives should undertake initiatives to develop local brands effectively, taking into consideration the factors that impact farmers’ engagement, while food marketing firms should properly adapt their purchasing and promotion strategies. Public authorities should formulate a policy mix that enhances farmers’ knowledge related to marketing issues and encourages farmers to strengthen their positions in the marketplace.

Originality/value

The research reveals a strategic proactive behavior of farmers favoring the development of local brands, and provides insights into the factors that impact farmers’ adoption decisions.

Abstract

The Internet and social media have fundamentally transformed the ways in which individuals find jobs. Relatively little is known about how demand-side market actors use online information and the implications for social stratification and mobility. This study provides an in-depth exploration of the online recruitment strategies pursued by human resource (HR) professionals. Qualitative interviews with 61 HR recruiters in two southern US metro areas reveal two distinct patterns in how they use Internet resources to fill jobs. For low and general skill work, they post advertisements to online job boards (e.g., Monster and CareerBuilder) with massive audiences of job seekers. By contrast, for high-skill or supervisory positions, they use LinkedIn to target passive candidates – employed individuals who are not looking for work but might be willing to change jobs. Although there are some intermediate practices, the overall picture is one of an increasingly bifurcated “winner-take-all” labor market in which recruiters focus their efforts on poaching specialized superstar talent (“purple squirrels”) from the ranks of the currently employed, while active job seekers are relegated to the hyper-competitive and impersonal “black hole” of the online job boards.

Abstract

Purpose

The purpose of this paper is to present a novel approach for recruiting and ranking job applicants in online recruitment systems, with the objective to automate applicant pre‐screening. An integrated, company‐oriented, e‐recruitment system was implemented based on the proposed scheme and its functionality was showcased and evaluated in a real‐world recruitment scenario.

Design/methodology/approach

The proposed system implements automated candidate ranking, based on objective criteria that can be extracted from the applicant's LinkedIn profile. What is more, candidate personality traits are automatically extracted from his/her social presence using linguistic analysis. The applicant's rank is derived from individual selection criteria using analytical hierarchy process (AHP), while their relative significance (weight) is controlled by the recruiter.

Findings

The proposed e‐recruitment system was deployed in a real‐world recruitment scenario, and its output was validated by expert recruiters. It was found that with the exception of senior positions that required domain experience and specific qualifications, automated pre‐screening performed consistently compared to human recruiters.

Research limitations/implications

It was found that companies can increase the efficiency of the recruitment process if they integrate an e‐recruitment system in their human resources management infrastructure that automates the candidate pre‐screening process. Interviewing and background investigation of applicants can then be limited to the top candidates identified from the system.

Originality/value

To the best of the authors’ knowledge, this is the first e‐recruitment system that supports automated extraction of candidate personality traits using linguistic analysis and ranks candidates with the AHP.

Abstract

Hit by an unprecedented financial crisis, the Greek society has been also swept away by an acute political crisis, rising political polarisation and social unrest. At the same time, over the last decade, Greece has faced an unparalleled state of emergency, with thousands of refugees and immigrants entering every year and remaining in the country, often in extremely difficult living conditions leading to ‘an exceptional crisis within the crisis’. In fact, during the recent years, immigration and the ‘refugee crisis’ have been among the most controversial topics on the Greek policy agenda and one of the principal issues that shapes public discourse and raises the most questions about social cohesion and the fundamental values of the Greek society. Media representations of the refugee and migrant ‘crisis’ have played a significant role in how this controversial issue is presented in the Greek public discourse as well as in how people perceive and respond to it. Within this context and having as a starting point the theoretical approach of peace journalism, this chapter explores the ways in which four national Greek newspapers portrayed immigration within different periods of the Greek crisis between January 2011 and September 2015. Research results reveal two different periods in the analysed news stories, one between 2011 and 2014, when immigration was portrayed as a ‘domestic problem’ and the other, in 2015, when the situation was designated as a ‘European refugee crisis’. In both cases, however, it was evident that immigration was positioned high on the agenda of the Greek newspapers, despite major political events taking place within the same periods. Findings were presented and discussed on four different but interrelated levels: immigration (1) as a source of conflict and polarisation, (2) as a political issue, (3) through securitisation and victimhood and, ultimately, (4) through a ‘journalism of conventions’ lens, with very important consequences on the quality of information (extensive lack of solutions related to immigration and asylum issues, absence of refugees' voice, insufficient context, among others).

Abstract

Purpose

Industry 4.0 emerged as the Fourth Industrial Revolution aiming at achieving higher levels of operational efficiency, productivity and automation. In this context, manual assembly systems are still characterized by high flexibility and low productivity, if compared to fully automated systems. Therefore, the purpose of this paper is to propose the design, engineering and testing of a prototypal adaptive automation assembly system, including greater levels of automation to complement the skills and capabilities of human workers.

Design/methodology/approach

A lab experimental field-test is presented comparing the assembly process of a full-scale industrial chiller with traditional and adaptive assembly system.

Findings

The analysis shows relevant benefits coming from the adoption of the adaptive automation assembly system. In particular, the main findings highlight improvements in the assembly cycle time and productivity, as well as reduction of the operator’s body movements.

Practical implications

The prototype is applied in an Italian mid-size industrial company, confirming its impact in terms of upgrades of the assembly system flexibility and productivity. Thus, the research study proposed in this paper provides valuable knowledge to support companies and industrial practitioners in the shift from traditional to advanced assembly systems matching current industrial and market features.

Originality/value

This paper expands the lacking research on adaptive automation assembly systems design proposing an innovative prototype able to real-time reconfigure its structure according to the product to work, e.g. work cycle, and the operator features.

Abstract

This paper looks at citizen‐facing e‐government. It considers how the non‐discretionary nature of the citizen’s relationship with government makes citizen‐facing e‐government different from business‐consumer e‐commerce. Combined with the moral basis of the state, the paper argues that there is an obligation for the state to set an example, which should affect the design of citizen‐facing e‐government, with design‐for‐all being an appropriate philosophy. Other consequences should include a preference for open standards and a wariness of unintentional endorsement of commercial products. E‐government should also offer a good level of data protection and security, and has a role in educating citizens in matters of computer security. Advantages and disadvantages that may come from e‐government adoption are considered, including a number of ways in which cost savings and increases in convenience may be achieved. There are brief discussions of questions of distribution of the benefits of e‐government adoption and of the relationship of e‐government to e‐democracy.

Abstract

Purpose

Rambutan (Nephelium lappaceum), a ubiquitous fruit in Southeastern Asia, was rich in vitamins and phytochemicals, which were beneficial for improving of skin conditions. The fermentation process increased phytochemicals and antioxidant capacity. Thus, the purpose of this paper is to examine whether phytochemicals can be increased through the fermentation process of rambutan extracts to improve skin aging.

Design/methodology/approach

In this study, the authors used the three stages of fermentation with Saccharomyces cerevisiae, Lactobacillus plantarum TCI028 and Acetobacter aceti under red light to develop a fermented rambutan extract.

Findings

The level of polyphenols of red-light-based fermented rambutan extract (RLFRE) were significantly increased 108.9% (p < 0.01) and 97% (p <0.01) compared with fermented rambutan extract (FRE) and pure rambutan extract (RE), respectively. The human skin fibroblasts treated with 0.03 or 0.06% of RLFRE can significantly decrease reactive oxygen species (ROS) levels by 0.74- (p <0.001) and 0.84-fold (p <0.001) compared with H2O2 group, respectively. And 0.03% of RLFRE can significantly increase in elastin content by 1.13-fold (p <0.05). Also, ten compounds were identified including one new phenolic compound and nine known compounds from RLFRE. Moreover, red light could enhance the levels of compounds 4, 9 and 3 by 5, 2.5 and 2.5-fold, respectively, relative to the results of FRE. The last, RLFRE isolated compounds significantly facilitated the elastin content on fibroblast (compound 1, 7, 9, 10 compared with control: p <0.001, compound 2 compared with control: p <0.001).

Originality/value

In short, this was the first study to unveil that the red-light-based fermentation can enrich the antioxidant content in a rambutan extract and its product had the potential to be developed a functional product for health-promoting effects such as skin aging.
