It is generally believed that, compared to traditional commerce, Electronic Commerce(EC) is more difficult to gain and sustain customers. One of the major reasons that customers do not use EC is lack of trust. Previous researches on the EC user's trust suggested that risk is an antecedent of trust and the concept of trust is highly related to risk. This study proposed a combined model in which includes the factors based on generic information security risk analysis methodology and trust factors in EC. The objectives of this study are follows; first, investigating the relationship between trust and risk that are antecedent factors of purchase intention, and second, examining the validity of information security risk analysis approach in EC environment. Based on the survey results of 143 MBA students statistical analysis showed that factors like threats and controls were significantly related to risk, but assets did not have statistically significant relationship with risk. Controls and knowledge of EC had meaningful effect on user's trust. This study found that risk analysis methodology which is generally used at organizational level is practically useful at user level on EC environment. In conclusion, the results of this study would be applied to generic situation of information security for analyzing and managing the risk. Besides, this study emphasized that EC vendors need to pay more attention to the information security risk to gain customer's trust.

Informational urbanism is a new research area in information science. In this study, art history joins informational urbanism: Are digital artworks in public urban spaces recognized as essential assets of a smart city? We employed case study research, working with the example of the huge digital media façade of the Arthouse Graz as an artwork in a public space. In a mixed-methods approach, we asked passers-by and interviewed experts on Graz as a smart city and on the Arthouse's role concerning the image of Graz as a smart city. The research found strong hints that indeed digital artworks with large screens or media façades at public spaces are parts of a city's weak location factors as well as of the city's urban structure and may symbolize the city's smartness. A practical implication of this finding is that artists, computer and information scientists, city planners, and architects should include interactive contemporary digital art into city spaces in order to demonstrate the city's way towards knowledge society.

An operation of an organization is currently using a digital environment which opens to potential cyber-attacks. These phenomena become worst as the cyberattack landscape is changing rapidly. The impact of cyber-attacks varies depending on the scope of the organization and the value of assets that need to be protected. It is difficult to assess the damage to an organization from cyberattacks due to a lack of understanding of tools, metrics, and knowledge on the type of attacks and their impacts. Hence, this paper aims to identify domains and sub-domains of cyber-attack taxonomy to facilitate the understanding of cyber-attacks. Four phases are carried in this research: identify existing cyber-attack taxonomy, determine and classify domains and sub-domains of cyber-attack, and construct the enhanced cyber-attack taxonomy. The existing cyber-attack taxonomies are analyzed, domains and sub-domains are selected based on the focus and objectives of the research, and the proposed taxonomy named AVOIDITALS Cyber-attack Taxonomy is constructed. AVOIDITALS consists of 8 domains, 105 sub-domains, 142 sub-sub-domains, and 90 other sub-sub-domains that act as a guideline to assist administrators in determining cyber-attacks through cyber-attacks pattern identification that commonly occurred on digital infrastructure and provide the best prevention method to minimize impact. This research can be further developed in line with the emergence of new types and categories of current cyberattacks and the future.

Entrepreneurs are valuable assets for any country. Rather than being confronted with new obstacles, they should be fostered and nurtured. Entrepreneurial firms have the power to influence how we live and work, in addition to producing jobs and contributing to economic progress. Entrepreneurs have the ability to change the world by creating diversified skill sets and profitable businesses that are vital to the advancement of our economies. How does one go about being a successful business, though? More resources are believed to be needed to create entrepreneurial environments in higher education that foster progressive ideas and innovation while also providing students with the practical knowledge and skills they need to navigate the troublesome, difficult, and uncertain situations that come with owning a business. This article will outline the scales of components from which to measure variables impacting universities' ability to encourage entrepreneurial behavior among students, based on the aforementioned significance of universities. This article is based on a survey of 507 students from different universities and backgrounds in Vietnam. The research methods used are Cronbach's alpha test and Structural Equation Modeling. From the research results, it can be seen that the university's environment plays a significant role in fostering entrepreneurial behavior among students.

In today's knowledge-based economy, measurement and disclosure (M&D) of intellectual capital (IC) are crucial for enhancing business performance and competitiveness. In the global world, M&D of IC are useful means to keep investors well-informed and reduce information asymmetry. At present, very few leading corporations in India have disclosed IC information on a 'voluntary' basis. Traditional accounting practices, therefore, will need to assimilate innovations that seek to meaningfully represent the 'true-value' of the intangible assets of the company. This is an exploratory study of IC M&D by 8 Indian companies over 5-year period, using 'content' analysis and market-value-added (MVA) as research methodologies. The annual reports of companies were collected from their respective websites. As part of present study, various statistical techniques have been used to analyze the data. The findings show that the sample companies, on an average, reported a positive value of IC, along with wide-disparity, low-level of ICD. Unfortunately, the omission of IC information may adversely influence the quality of decisions made by shareholders, or lead to material misstatements. Finally, we recommend to "the international accounting bodies, to take the lead by establishing a harmonized ICD standard, and provide guidance to the big listed-companies for proper measurement and disclosure of IC, both for internal and external users."

The failures of tailing dams have caused irreparable damage to human lives, assets and environment and this has ultimately resulted in great economic, social and environmental challenges worldwide. Due to this, investigation into mechanical behaviour of tailings has received some attention. However, the knowledge and understanding of mechanics of behaviour in iron tailings is still limited. This study investigates the mechanics of iron tailings from Nigeria considering grading, effects of fabric resulting from different sample preparations and the possibility of non-convergent behaviour. This was achieved by conducting series of one-dimensional compression tests in conjunction with index, microstructural, chemical and mineralogical tests. The materials are predominantly poorly graded, non-clayey and non-plastic. The tailings are characterised by angular particles with no obvious particle aggregations and dominated by silicon, iron, aluminium, haematite and quartz. The compression paths do not converge and unique normal compression lines are not found and this is an important feature of the transitional mode of behaviour. The behaviour of these iron tailings therefore depends on initial specific volume. The preparation methods also have effect on the compression paths of the samples. The gradings of the samples have an influence on the degree of transitional behaviour but the preparation methods do affect the degree of convergence. The transitional mode of behaviour in these iron tailings investigated is very strong.

The comprehension and structural modeling of masonry constructions is fundamental to safeguard the integrity of built cultural assets and intervene through adequate actions, especially in earthquake-prone regions. Despite the availability of several modeling strategies and modern computing power, modeling masonry remains a great challenge because of still demanding computational efforts, constraints in performing destructive or semi-destructive in-situ tests, and material uncertainties. This paper investigates the shear behavior of masonry walls by applying a plane-stress FE continuum model with the Modified Masonry-like Material (MMLM). Epistemic uncertainty affecting input parameters of the MMLM is considered in a probabilistic framework. After appointing a suitable probability density function to input quantities according to prior engineering knowledge, uncertainties are propagated to outputs relying on gPCE-based surrogate models to considerably speed up the forward problem-solving. The sensitivity of the response to input parameters is evaluated through the computation of Sobol' indices pointing out the parameters more worthy to be further investigated, when dealing with the seismic assessment of masonry buildings. Finally, masonry mechanical properties are calibrated in a probabilistic setting with the Bayesian approach to the inverse problem based on the available measurements obtained from the experimental load-displacement curves provided by shear compression in-situ tests.

지금까지 제시된 지적자본의 공통요소들은 브랜드나 상표 그리고 정보기술 등과 같은 유형적인(intangible) 지적자본 요소들이 중심을 이루고 있다. 특히 기업가치창출의 근간이 되는 인적자본, 즉 내부고객에 대한 부분도 많은 부분 간과하고 있는 것이 사실이다. 지식자산의 측정에 관해서 국내기업이 당면한 문제점을 요약하면 다음과 같다. 첫째, 무형자산의 감사와 측정이 지속적으로 이루어지지 않아 조직이 필요한 지적자본의 내역과 경쟁기업과의 지식격차를 정확히 판단하지 못하고 있다. 둘째, 지식발굴 노력의 부족과 잦은 부서 이동, 고용조정 등에 따라 지식이 유실되고 축적되고 있지 못하다. 셋째, 조직내부의 정치적인 역학관계로 인해 경영활동의 실패사례가 사실대로 기록될 수 없는 것이 현실이며, 그나마 축적된 지식도 체계적인 관리가 부족하여 활용도가 저조하다. 넷째, 부문별 벤치마킹을 통해 선진사례나 지식이 이전되고 경영활동은 개선되었으나 타부서로 이전되지 않아 최선의 실행사례(best practice)가 자산으로 공유되지 못하고, 지식창출을 위한 중복투자가 발생한다. 다섯째, 지나친 성과중심형 지표들로 인해 성과를 창출해 내는 조직구성원들에 체화된 역량과 태도, 만족부분을 간과함으로 인해 미래 성과창출의 원동력이 되는 관리지표를 개발하는데 한계를 드러냈다. 이러한 문제점들은 국내 기업들의 지식경영, 혹은 지적자본 경영체제가 닫혀진 조직문화와 경영시스템의 미비, 그리고 전담조직의 부재와 최고경영층의 관심부족으로 인해 조직적, 인간적 지식인프라가 완성되어 있지 못하기 때문인 것으로 생각된다. 따라서 지식경영의 성숙기에 접어든 외국의 지적자본 측정요소와 국내 유통업체의 현실을 고려한 지적자본 측정지표에 대한 개발이 필요하다. 이러한 관점에서 지적자본과 연구개발평가의 이론, 기존 연구결과의 분석 등 기존에 발표된 문헌분석을 통해 국내 유통업체에 적용가능한 측정지표를 도출해보고, 적용가능한 범위를 고찰하고자 한다.
