Electrical properties of biogenic material: bilirubin rich gallstone
The electrical properties of Bilirubin Rich Gallstone (BGS) were investigated by the Complex Impedance Spectroscopy (CIS) technique. The dielectric relaxation was found to be of non-Debye type. Evidences of temperature-dependent electrical relaxation phenomena as well as Negative Temperature Coefficient of Resistance (NTCR) character of the sample have been observed. The ac conductivity obeys the ...

Social network ties and resource acquisition: evidence from China`s transitional economy
Based on the system perspective, we develop a theoretical model for the relationship between social network (SN) ties and resource acquisition (RA) and examine how environmental dynamism (ED) moderates this relationship, then conduct empirical analysis using data of 326 new firms Jilin province of China. The result suggests that SN ties have positive effects on external RA and internal resource ...

The impact of timely succession planning on a firm's continuity: case of Lebanon
This paper examines whether early succession planning in Lebanese family-owned firms has an immediate impact on their financial performance and hence their continuity. We have surveyed 50 privately held Lebanese family-owned firms and conducted a statistical analysis of their responses. Our findings show that early and proper succession planning impacts future financial performance rather than ...

A comparative study of the alliance experiences between US and Taiwanese firms
The major purpose of this study is to conduct a comparative analysis between US and Taiwanese firms for examining similarities and differences of their alliance experiences. The results indicate that first, US and Taiwanese firms have different alliance behaviours in the choice of alliance form and alliance type. Secondly, in general, the intensity of formation motive and partner interaction is ...

Large-scale open innovation: open source vs. patent pools
The traditional view of the innovation, which implies that companies innovate on their own, has been recently challenged by the ‘open innovation’ concept promoting the use of external knowledge. Collaboration between firms has always existed in one way or another, however, large-scale open innovation is now the next step for many companies. This article conducts a comparative analysis of the two ...

Measurement and Analysis of Lengthwise Rail Shock
Introduction: A shock pulse is defined by Cyril M. Harris in Shock & Vibration Handbook as "a substantial disturbance characterized by a rise of acceleration from a constant value and decay of acceleration to a constant value in a short period of time." Lengthwise shocks occur in normal rail handling as a result of yard classification of cars and train slack action. The result of rail shock ...

Commercialisation of technology innovations: an empirical study on the influence of clusters and innovation networks
The current body of literature offers contradictory results concerning the role of clusters and innovation networks in the commercialisation of high technology. Whereas several previous studies verify the overall beneficial effects of cluster membership for knowledge-intensive firms, others report that clusters have only little or no influence on technology firms’ economic success. The major ...

Church institution and digital world: new opportunities to profess the word of God
The purpose of this paper is to investigate the relationship between church institution and new technology in the field of communication and management of the religious tourism experience. A critical study of the institutional church use of new technology applications for the communication, management and promotion of ecclesiastic heritage is developed; an empirical phase is implemented by ...

Virtual worlds in higher education: a policy simulation
The purpose of this paper is to explore whether virtual worlds can provide a setting for a rewarding learning experience for college students. The paper describes a policy-making simulation conducted within a virtual world and the results of an analysis conducted to assess its learning effectiveness. Our analysis, drawn from eight 'learning principles' advanced by Gee (2003), indicates that the ...

Multifunctionality: epistemic diversity and concept oriented research clusters
This paper provides a mapping of the different uses of the word multifunctionality. To explore the diversity of meanings and interpretations, a comparative analysis was conducted through five national case studies in France, the Netherlands, Poland, Spain and Switzerland. The analysis conducted at national level makes it possible to identify eight Concept Oriented Research Clusters (CORCs), based ...

Analysing online shopping attributes to influence consumer purchasing for fashion products
The fashion industry has stepped into the digital era. There are a great number of firms moving to be the digital companies with the major business process all being supported by the internet (Hajji et al., 2012; Bruce and Daly, 2011). A recent study from Mintel (2012) finds that online fashion purchase has increased by 152% in the UK over the last five years. The aim of this study is to ...

The impact of innovation management implementation on enterprise competitiveness among Taiwan's high-tech manufacturers
Innovation is an important topic in the 21st century. Innovation management has become a compulsory path to sustained enterprise growth. In this research, we studied the degree of innovation implementation among domestic high-tech manufacturers and the impact of innovation management implementation on competitiveness. We considered the mediating variables of "industry type" and "enterprise ...

Exergy transfer analysis of a pin fin in external flow
Based on the non-equilibrium thermodynamic theory, a general exergy transfer model is developed to describe the exergy transfer characteristics of external convection by using Black Body Approach. This model is applied to the study of fin efficiency for exergy transfer, which is defined as the ratio of the actual exergy transfer rate to the ideal exergy transfer rate. Both the analytical ...

Overview of the systems of systems engineering methodology
There is no widely accepted approach to conducting system of systems engineering (SoSE) efforts. The SoSE methodology is a rigorous engineering analysis that invests heavily in the understanding and framing of the problem under study. By conducting a rigorous engineering analysis of the problem and its associated context, the SoSE methodology minimises the chance that a Type III error may be ...

Graphical design for stability of linear active disturbance rejection control to first order time delay plants
In this paper, a Linear Active Disturbance Rejection Control (LADRC) scheme is presented for the uncertain first order delay time plant. The stable boundary is obtained, which make the tuning process very easy. The controller can be applied to a plant with large time delay. The uncertainty of the system is characterised by the Kharitonov theorem and the gain–phase margin tester approach, ...

Fecal indicator and Ascaris removal from double pit latrine content
Since May 2006, the BRAC Water, Sanitation and Hygiene (WASH) Programme in Bangladesh has enabled more than 30 million people to achieve hygienic sanitation, contributing to an increase in sanitation coverage from 33 to 83% in programme areas and rapid progress towards universal access. In rural areas, most families have single pit latrines that need to be emptied when full. Since 2007, BRAC ...

Global value chain reconfiguration through external linkages and the development of newcomers: a global story of clusters and innovation
Industrial district literature has focused on local endogenous development. So far, these works analyse the external ties between clusters and the reconfiguration of global value chains (GVC) in the last decade, opening a new research stream to understand innovation and its impact on differing territories. This article analyses intercluster linkages through multinational enterprise (MNE) ...

Aerodynamic instability of cable-supported bridges considering the initial deformed shape due to dead loads
The aerodynamic instability of cable-supported bridges is studied, with due account taken of the initial deformed shape of the bridge due to the dead loads. The two-node catenary cable element is adopted to model the non-linear behaviours of cables with sags of various magnitudes. Self-excited wind loads are expressed in terms of flutter derivatives. The aerodynamic instability analysis is ...
