Covert Photonic Barcodes Based on Light Controlled Acidichromism in Organic Dye Doped Whispering‐Gallery‐Mode Microdisks

Photonic barcodes with a small footprint have demonstrated a great value for multiplexed high‐throughput bioassays and tracking systems. Attempts to develop coding technology tend to focus on the generation of featured barcodes both with high coding capacity and accurate recognition. In this work, a strategy to design photonic barcodes is proposed based on whispering‐gallery‐mode (WGM) modulations in dye‐doped microdisk resonant cavities, where each modulated photoluminescence spectrum constitutes the fingerprint of a corresponding microdisk. The WGM‐based barcodes can achieve infinite encoding capacity through tuning the dimensions of the microdisks. These photonic barcodes can be well disguised and decoded based on the light controlled proton release and acidichromism of the organic materials, which are essential to fulfill the functions of anti‐counterfeiting, information security, and so on. The results will pave an avenue to new types of flexible WGM‐based components for optical data recording and security labels.     

Understanding the role of ICT and study circles in enabling economic opportunities: Lessons learned from an educational project in Kenya

In this paper, we explore how the combination of Information and Communication Technologies (ICT) and self‐organised study circles improves rural communities' ability to enhance their economic opportunities. We present the case study of an adult study‐circle project in the Kwale County of Kenya with the objective of providing rural communities with viable and sustainable livelihoods. Study circles can be seen as a democratic and emancipatory method for learning, where community groups regularly meet for participatory discussions to educate themselves on a variety of topics of their own interest. The main goal of the study‐circle members was to increase economic opportunities using ICT and, more specifically, to start micro‐businesses, improve production efficacy and methods, and obtain employment. Using the capability approach and affordances as theoretical lenses, our analysis of the explorative case study shows that the outcomes of the study circle were dependent on various conversion factors and facilitating conditions, such as resources, skills, socio‐cultural norms, and infrastructure. The main contributions from our work are represented by the five practical lessons learned from the study‐circle members' goals (starting micro‐businesses, product efficiency, and obtaining employment) from the self‐organised training approach (study circles) and from our theoretical approach (combining the capability approach and affordances).     

ICT for socio-economic development: A citizens’ perspective

There is a widespread belief that information and communication technologies (ICTs) can play a significant role in the socio-economic development of a developing country. ICT has the potential to affect many aspects of economic and societal activities such as GDP growth, employment, productivity, poverty alleviation, quality of life, education, and healthcare. While the literature provides a myriad of definitions and elements of socio-economic development, the focus tends to be on theoretical conceptualizations from various disciplines and impacts from isolated individual projects. In particular, the impact of ICT on socio-economic development has not been carefully examined from the viewpoint of the ultimate stakeholder, the citizens of a country, who are the final consumers of the technology. This study fills this gap by focusing on the citizens’ view in describing ICT-driven socio-economic development in a developing country. A theoretical framework influenced by the “capabilities approach” was developed to guide this research, and the interpretive stance was used to conduct the study. More specifically, the narrative research method, which is seldom used in IS research but is appropriate for this study, was used. Narratives allow deeper and profound insights into social representations and participants' beliefs about the role of ICT in socio-economic development. Using this methodology, a model of the impact dimensions of socio-economic development is presented.     

三维工业CT图像裂纹面检测*

利用工业CT扫描工件可得到包含工件内部裂纹的三维CT图像,而将裂纹面从CT图像中提取出来是对裂纹属性进行分析的关键,对确保工件可靠性具有重要的意义。针对直接3D C-V模型提取裂纹面速度慢的特点,研究了三维小波与C-V模型相结合的图像分割方法,提高裂纹图像分割速度。实验结果表明,与直接3D C-V模型相比,该方法可将三维C-V模型提取裂纹的速度提高大约1.5倍,为后续裂纹分析打下基础。     

Consumers’ acceptance of information and communications technology in tourism: A review

The impact of information and communications technology (ICT) in tourism (e-tourism) has altered the ways tourism services are accessed and consumed. Ubiquitous and highly innovative ICTs provide different channels for consumers to use tourism services; thus, studies on e-tourism are numerous and fragmented. Different factors account for how consumers embrace these channels. The purpose of this study is to review studies on consumers’ acceptance or adoption of e-tourism in order to group the studies, synthesize the theories, models and frameworks used and identify the antecedents influencing consumers’ e-tourism acceptance and usage. A total of 71 studies from 2005 to 2016 (inclusive) from both tourism-based and non-tourism-based journals were selected, synthesized, and included. Based on their contexts, similarity and relevance, the 71 studies were segregated into three distinct groups. This study found that research among the groups is uneven. Implications and research directions are suggested.     

The politics of co-design in ICT for sustainable development

ABSTRACT

In this paper, we discuss an approach to co-design in ICT for sustainable development. We first set out to consider sustainable development as incorporate a concern for resilience, adaptability, and autonomy. We then draw on an ongoing participatory design project to illustrate how co-design projects can be configured, along with the political choices that this entails, to support such development.

Mapping ICT use at home and telecommuting practices: A perspective from work/family border theory

This study draws on the work/family border theory to investigate the role of information communication technology (ICT) use at home in shaping the characteristics of work/family borders (i.e. flexibility and permeability) and consequently influencing individuals’ perceived work-family conflict, technostress, and level of telecommuting. Data were collected from a probability sample of 509 information workers in Hong Kong who were not self-employed. The results showed that the more that people used ICT to do their work at home, the greater they perceived their work/family borders flexible and permeable. Interestingly, low flexibility and high permeability, rather than the use of ICT at home, had much stronger influences on increasing, in particular, family-to-work conflict. As expected, work-to-family conflict was significantly and positively associated with technostress. Results also showed that the telecommuters tended to be older, had lower family incomes, used ICT frequently at home, and had a permeable boundary that allowed work to penetrate their home domain. The theoretical and practical implications are discussed.
