Abstract

Purpose

The purpose of this paper is to propose a binocular visual odometry algorithm based on the Random Sample Consensus (RANSAC) in visual navigation systems.

Design/methodology/approach

The authors propose a novel binocular visual odometry algorithm based on features from accelerated segment test (FAST) extractor and an improved matching method based on the RANSAC. Firstly, features are detected by utilizing the FAST extractor. Secondly, the detected features are roughly matched by utilizing the distance ration of the nearest neighbor and the second nearest neighbor. Finally, wrong matched feature pairs are removed by using the RANSAC method to reduce the interference of error matchings.

Findings

The performance of this new algorithm has been examined by an actual experiment data. The results shown that not only the robustness of feature detection and matching can be enhanced but also the positioning error can be significantly reduced by utilizing this novel binocular visual odometry algorithm. The feasibility and effectiveness of the proposed matching method and the improved binocular visual odometry algorithm were also verified in this paper.

Practical implications

This paper presents an improved binocular visual odometry algorithm which has been tested by real data. This algorithm can be used for outdoor vehicle navigation.

Originality/value

A binocular visual odometer algorithm based on FAST extractor and RANSAC methods is proposed to improve the positioning accuracy and robustness. Experiment results have verified the effectiveness of the present visual odometer algorithm.

Abstract

Purpose

In their 2007 article, “Miranda in the brave new world: learning in a Web 2.0 millennium”, Barnes and Tynan tell the story of an imaginary British student who uses technology seamlessly to stay connected almost 24×7 with friends, peers and teachers in a global learning environment. Whether she is representative of the majority of university students is a topic of debate in the literature. This paper aims to explore how students use technologies in their everyday lives, whether on‐ or off‐campus, to support their learning.

Design/methodology/approach

There were two phases of the study; a photo ethnography to enable a detailed exploration of ten students' technology uses and then a university‐wide survey in which 1,104 student responses were gathered.

Findings

The findings of both phases of the study suggest that students' use of technologies for their learning and in other facets of their lives is largely conservative, with a predominance of familiar and easy‐to‐use tools such as e‐mail, text and mobile phone. For their learning, their preference is for tools to provide access, efficiency and connectedness.

Originality/value

This paper contributes to the development of a better understanding of student issues in the context of their overall IT experience at the university, suggesting a more holistic approach to designing technology infrastructure. There are also insights into the power of mixed methodologies in research, with significant parallels between the qualitative and quantitative results.

Abstract

Purpose

The purpose of this paper is to identify the actual uses of smartphones for university students while they are in the university, whether in the classroom or outside, to facilitate the use of mobile technologies in the university and in classroom activities.

Design/methodology/approach

The site was the main campus of a university with a population of 10,000 undergraduate students; a convenience sample of 370 students was estimated for 246 usable surveys, with 95% confidence interval and 6.12 percent error. The proposed conceptual framework is based on the unified theory of technology acceptance. The instrument was developed on the basis of the literature and it was validated through a qualitative–quantitative process. The data were collected fact-to-face and the analysis consisted of the estimation of a general profile, mean and standard deviation and the development of the ordinal logistic regression model to test the hypothesis. Minitab 16 was the program used for the calculations.

Findings

The instrument was found to be acceptable with a 0.90 α. The uses associated with the academic activities are: p8_1 search what I do not understand in the class, p5_1 read digital books, pdf and other documents, p9_1 study, p11_1 share course information and p2_1 take photos of class blackboard and another type of materials. For non-academic uses, the uses were: p14 calendar, p4 listening to music, p9 telephone calls and p7 interacting with new students. The adaptation of mobiles to university education has to harmonize students’ use, professors’ objections and institutional concerns; therefore, four elements are needed before a decision is made: professors’ training, teaching material development, infrastructure adaptation and a sound plan.

Research limitations/implications

The selection of students was a convenience sample; therefore, the results cannot be extrapolated beyond the sample.

Practical implications

The study clarifies the traditional idea popular in the area, that is, students use the mobile only for entertainment, and suggests ways to managerially deal with the issue in an orderly fashion, by investing in human capital, infrastructure and electronic teaching tools.

Originality/value

The value is that the findings provide some ideas regarding the uses of smartphones for university students while they are in the university; such information can be used to orient strategies to develop educational uses of the smartphone.

Abstract

Purpose

This study aims to evaluate factors influencing undergraduate students’ acceptance of a computer-aided learning resource using the Phantom Omni haptic stylus to enable rotation, touch and kinaesthetic feedback and display of names of three-dimensional (3D) human anatomical structures on a visual display.

Design/methodology/approach

The software was developed using the software development life cycle, and was tested by students enrolled in various bachelor degrees at three stages of development within the technology acceptance model, action research and design research methodology frameworks, using mixed methods of quantitative and qualitative analysis.

Findings

The learning system was generally well-accepted, with usefulness (72 ± 18, mean ± standard deviation, 0-100 visual analogue scale) rated higher (p < 0.001) than ease of use (57 ± 22). Ease of use ratings declined across the three versions as modules were added and complexity increased. Students with prior experience with 3D interfaces had higher intention to use the system, and scored higher on identification of anatomical structures. Students with greater kinaesthetic learning preferences tended to rate the system higher. Haptic feedback was considered the best aspect of the system, but students wanted higher spatial resolution and lower response times.

Originality/value

Previous research relating to haptic devices in medical and health sciences has largely focused on advanced trainees learning surgical or procedural skills. The present research suggests that incorporating haptic feedback into virtual anatomical models may provide useful multisensory information in learning anatomy at the undergraduate level.

Abstract

Purpose

The aim of this paper is to illustrate how scholars may adopt a multi‐method – not just multidisciplinary – approach on research on conflict management. Taking the Diaoyu Islands as a case, the author draws on literature from management, political sciences, war, military studies, history, etymology and culture. In the process, the author deepens, enriches and expands the Thomas‐Kilman (T‐K) model for mapping out possible solutions in resolving conflicts: not just between people at workplaces but for between states as well. For instance, the author explains why the Diaoyu Islands conflict, if not amicably resolved may well lead to obliteration (integrated as part of the model) in resolving the conflict via a nuclear outbreak. Third World War may just be sparked off with Russia aligned with China against Japan and the USA.

Design/methodology/approach

Of all the issues in management, conflict management is the most culturally embedded. Through a multi‐method approach, the author illuminates the complexity of the Diaoyu Islands case. Literature from past empirical war studies are reviewed to suggest the geography of the islands (proximity, borderless, richness of resources) makes war highly probable. Past Chinese‐Japanese hatred (utilizing visual imagery), antagonism and guanxi are reviewed in exploring their impacts on outcomes (see model). Etymological research is attempted using English, Japanese and Chinese words, characters and pictograms that are related to concepts within the T‐K model. To better grasp how young Chinese feel towards the Diaoyu Islands and the Japanese, the author conducted some field research in Harbin, China. The continuing Chinese angst against Japanese is explained through war imagery: there remains in young Chinese an unquenchable thirst for exacting revenge on the Japanese. In a search to uncover ways of resolving the dispute, a further, extended study is undertaken on ancient Chinese pictograms: for example, whether a 5,000 years old Chinese concept of compromise zhe zhong (Graphic 1; oracular bones) or splitting into halves may be relevant. The role of time in conflict management is discussed in relation to the Diaoyu Islands.

Findings

By providing the WWII visual imagery as a backdrop to Chinese‐Japanese antagonism, the author explains to readers why the Diaoyu Islands is such a complex case to resolve. Also in his fieldwork, he highlights that the younger Chinese are as equally indignant about Japanese unethical grabbing, “thieving” behaviour. In their minds, such behaviour harks back to the blatant seizure of Manchuria and Japanese puppetry of Manchukuo. Through the Diaoyu Islands case, the T‐K model and theory of conflict management is broadened, enriched and enhanced. The paper illustrates how in conflicts that involve cultures are very different from the West, for instance very ancient civilizations like China and India, authors should take a multi‐method approach and explore the issues and search for solutions far more deeply.

Originality/value

Very few scholars seek to integrate the two streams of research in resolving conflict as illustrated through this paper: management and social sciences (e.g. political sciences, military and war studies). Conflict is about people and therefore integral use of multi‐methods needs to be used.

Abstract

Purpose

This paper aims to reorganize the relevant information of Chinese ancient architectures with the use of Semantic Web technologies and thus facilitate its deep discovery and usage.

Design/methodology/approach

This paper proposes an ontology model for Chinese ancient architectures based on architectural narratives theory. To verify the availability of the ancient architecture ontology, we designed and implemented three experiments, including semantic retrieval based on SPARQL query, semantic reasoning with the use of Jena reasoner and visual analysis based on the Chinese Online Digital Humanities Resources Platform.

Findings

The proposed ontology provided a solution for the semantic annotation of the unstructured information of Chinese ancient architectures. On this basis, deep knowledge services such as semantic retrieval, semantic reasoning and visual analysis can be provided.

Practical implications

The proposed semantic model of ancient architectures can effectively improve the organization and access quality of the semantic content of Chinese ancient architectures.

Originality/value

This paper focuses on the semantic modelling for the unstructured information of Chinese ancient architectures to semantically describe the related entities (e.g. persons, events, places and times) and uncover their relationships, and thus it made contribution to the deep semantic annotations on ancient architectures.

Abstract

Purpose

This article was based on the information from The 5th International Conference of Institutes and Libraries for Chinese Overseas Studies held in the University of British Columbia in Vancouver, BC, Canada in which the author was a presenter in session 4.2.9a of the Early life of Yuan Shikai and the formation of Yuan family. The paper aims to include comprehensive analysis and development of the history of Chinese migration. An annotated bibliography of suggested readings was offered to highlight the subject knowledge for further research in this area.

Design/methodology/approach

The paper includes comprehensive analysis and development of the history of Chinese migration and the experiences and family histories of overseas Chinese in Canada. An annotated bibliography of suggested readings was offered to highlight the subject knowledge for further research in this area.

Findings

The paper offers full description and comprehensive analysis of the history of Chinese migration and overseas Chinese studies in Canada. A bbibliography of suggested readings was offered for further research in this area.

Research limitations/implications

This research study has a strong subject focus on Chinese migration, overseas Chinese studies, and resource-sharing in the subject area. It is a specific field for research in Asian studies.

Practical implications

The result of this study will assist students, researchers, and the general public in the area of overseas Chinese studies and developing their interests in the social and historical value of Chinese migration history and resource-sharing in the area.

Originality/value

Very little research has been done in the area of Chinese migration and historical development. The paper would offer historians, sociologists, ethnologists, librarians, administrations, professors, as well as students in the fields of Asian history, anthropology, sociology, political science, geography, and other Asian-related interdisciplinary studies.

Abstract

Purpose

This study aims to determine how the prices of residential properties in the Greek real estate sector are affected by their structural characteristics and by the prevailing economic factors during recession.

Design/methodology/approach

Based on 13,835 valuation reports for the city of Athens, covering a period of 11 years (2006–2016), this study develops a series of econometric models, taking into account both structural characteristics of the property market and the macroeconomic relevant variables. Finally, the city of Athens is divided into sub-regions and the different effects of the structural factors in each area are investigated via spatial analysis confirming the validity of the baseline model.

Findings

Findings show that the size, age, level, parking and storage space can explain the property price movements. Moreover, the authors find evidence that it is primarily house demand variables (e.g. the annual average wage, the unemployment rate, the user cost of capital, financing constraints and expectations about the future course of the house market) that affect house prices in a statistically significant manner and with the correct sign. Finally, using a difference-in-differences approach, this study finds that an increase in house demand (on account of net migration) led to higher house prices in smaller and older than in larger and younger apartments in areas with high concentration of immigrants.

Originality/value

This study uses a novel data set to help entities, individuals and policy-makers to understand how the recent economic and financial crisis has affected the real estate market in Athens.
