- Routing protocol for low power and lossy networks (RPL) is the underlying routing protocol of 6LoWPAN, a core communication standard for the Internet of Things. RPL outperforms other wireless sensor and ad hoc routing protocols in quality of service (QoS), device management, and energy saving performance. The Rank concept in RPL serves multiple purposes, including route optimization, prevention of loops, and managing control overhead. In this paper, we analyze several different types of internal threats that are aimed at the Rank property and study their impact on the performance of the wireless sensor network. Our analysis raises the question of an RPL weakness, which is the lack of a monitoring parent in every node. In RPL, the child node only receives the parent information through control messages, but it cannot check the services that its parent provide hence it will follow a bad quality route if it has a malicious parent. Our results show that different types of the Rank attacks can be used to intentionally downgrade specific QoS parameters. This paper also reveals that attack in a high forwarding load area will have more impact on network performance than attack in other areas. The defenders can use the knowledge of such correlation between attack location and its impact to set higher security levels at particular positions by monitoring sensitive network parameters and detecting the anomalies © 2001-2012 IEEE.

- Innovation has been recognized as one of the main determinants of nation’s economic development and has been adopted as a main tool for adding value and achieving sustainable competitive advantage. In order to understand the influence of global competitiveness on global innovation of nations, this study analyzed some indexes of 133 countries using a multiple linear regression analysis. The results suggested that global competitiveness influences the innovativeness of nations significantly and positively. Higher education and training was the competitiveness indicators that most influenced in innovation of nations.

Tidskriftsartikel (refereegranskat)abstract
- By understanding organizations in depth, it is possible to perceive some interactions of organizations with other organizations and with their environment. This research aims to understand the dimensions that explain the relationship network existing between a technology-based incubator and a university located in the region of the Itajaí valley. Methodologically this study is characterized as descriptive in relation to its objective, as for the procedures it can be considered as applied research from the survey of primary data and qualitative in relation to the approach of the problem. Thus, the main results have identified that the main relationship between the incubator and the university lies in the structure of the board of directors of the incubator, where the dean of administration is the chairman of the incubator's board. Therefore, although there are some deficiencies in the relations between institutions, it can be considered as the bridge of success.

Konferensbidrag (refereegranskat)abstract
- This paper presents an educational serious game aimed at raising awareness about ophthalmic issues. The game, titled’Disability Racer,’ is based on the mechanics of a car battle-royale and was developed for the computer platform. It incorporates four ophthalmic conditions, challenging players to compete against each other while experiencing impaired vision. To mirror real-life problem-solving, the’glasses’ item has been included, which, when collected, temporarily improves the player’s vision. In this way, the game promotes an understanding of the importance of regular ophthalmic check-ups. Copyright © 2024 by SCITEPRESS – Science and Technology Publications, Lda.

- A construct of conscientious corporate brands (hereinafter called CCBs) is tested by examining the environmental and climate change issues, and the internal and external corporate codes of ethics as dimensions of CCBs. The objective is to validate research in ethical branding by testing 'the conscientious dimension' of a corporate brand. The study is based upon Taiwanese business-to-business relationships.

An examination of the codes of ethics artifacts in top Taiwanese companies

Tidskriftsartikel (refereegranskat)abstract
- This study examines the use of codes of ethics artefacts among top companies in Taiwan. This research reports on the responses of those top Taiwanese companies that possessed a code of ethics. The empirical findings are compared to the findings of previous research. Top Taiwanese companies appear not to be drastically different from top companies in other countries in terms of the areas examined. Several similarities have been revealed. This study provides valuable insights into a previously unexplored corporate territory in terms of codes of ethics artefacts. Furthermore, it provides a seed and guidance for further research in other corporate cultures worldwide. Two parts of interest to business practices may be distinguished in terms of corporate codes of ethics artefacts, namely a regulatory one and one that supports staff. It also provides a valuable point of reference to previous research of corporate codes of ethics artefacts. Copyright © 2009 Inderscience Enterprises Ltd.

'Antecedents' and 'postcedents' in relation to satisfaction in Taiwanese business relationships
- 2010
-

-
Tidskriftsartikel (refereegranskat)abstract
- The research objective is to test whether satisfaction in business relationships may constitute a mediating construct between trust and commitment on the one hand, and coordination, cooperation and continuity expectancy on the other. The structural relationships are summarised in an AMP-model (i.e., antecedents, mediator and postcedents), the sample at that time consisted of attitudes among leading executives in small and medium-sized companies in Taiwan. The tested structural relationships of the AMP-model complement previous theory and research of antecedents and postcedents in relation to satisfaction in business relationships. One contribution is that the empirical findings indicate that satisfaction in studied buyer-supplier relationships may be seen as a mediating construct between antecedents (such as trust and commitment) and postcedents (such as coordination, cooperation and continuity). Research limitations and suggestions for further research are provided. Copyright © 2010 Inderscience Enterprises Ltd.

- This paper describes and compares Taiwanese and Turkish corporate perceptions of their commitment to ethics. Major differences in perceptions were found indicating that companies in Turkey appear to be more committed to ethics than in Taiwan. The findings are of interest to business practitioners as they provide insight into the implementation and supporting measures required to enhance the perceived corporate commitment to ethics. The empirical and interpretive findings make a valuable contribution to the literature and serve as point of reference in the field that will benefit future researchers working in business ethics.

Tidskriftsartikel (refereegranskat)abstract
- The objective of this paper is to test a measurement model of RELationship QUALity (RELQUAL) in Taiwanese business relationships. The sample consisted of leading executives in small and medium-sized companies (40-250 employees) in Taiwan. Principally, the respondents were general managers or division managers (e.g., within purchasing, logistics or production). The data, focusing on buyer-supplier relationships, was collected in 2008. A total of 168 questionnaires were returned, generating a response rate of 12%. The goodness-of-fit measures of the tested measurement model of RELQUAL were all found to be well within the recommended guidelines. The recommended guidelines for convergent, discriminant and nomological validity, as well as construct reliability, were also met. It is concluded that the measurement properties of the RELQUAL applied in Taiwanese business relationships indicate acceptable validity and reliability. Copyright © 2010 Inderscience Enterprises Ltd.
