    The entrepreneurial intention takes a major role in providing a new business creation. Despite major studies that have shown that entrepreneurship education is influential in driving intentions, few discuss this relationship by involving individual entrepreneurial orientation and internship motivation. This study is designed to investigate determinant factors affecting university students’ entrepreneurial intentions. To understand the nexus between entrepreneurship education and college students’ entrepreneurial intention, the hypotheses provide the intermediary role of entrepreneurial orientation, and this study presents evidence from Indonesia on the link between internships and intention for business. Using structural equation modeling (SEM) with partial least squares (PLS), the findings indicate that students’ entrepreneurial orientation and entrepreneurship education can drive students’ internship motivation and intention for entrepreneurship. Furthermore, it is de monstrated that internship motivation can moderate the link between entrepreneurial orientation, entrepreneurship education, and university students’ entrepreneurial intention

    Re-structuring of marine communities exposed to environmental change: a global study on the interactive effects of species and functional richness

    Species richness is the most commonly used but controversial biodiversity metric in studies on aspects of community stability such as structural composition or productivity. The apparent ambiguity of theoretical and experimental findings may in part be due to experimental shortcomings and/or heterogeneity of scales and methods in earlier studies. This has led to an urgent call for improved and more realistic experiments. In a series of experiments replicated at a global scale we translocated several hundred marine hard bottom communities to new environments simulating a rapid but moderate environmental change. Subsequently, we measured their rate of compositional change (re-structuring) which in the great majority of cases represented a compositional convergence towards local communities. Re-structuring is driven by mortality of community components (original species) and establishment of new species in the changed environmental context. The rate of this re-structuring was then related to various system properties. We show that availability of free substratum relates negatively while taxon richness relates positively to structural persistence (i.e., no or slow re-structuring). Thus, when faced with environmental change, taxon-rich communities retain their original composition longer than taxon-poor communities. The effect of taxon richness, however, interacts with another aspect of diversity, functional richness. Indeed, taxon richness relates positively to persistence in functionally depauperate communities, but not in functionally diverse communities. The interaction between taxonomic and functional diversity with regard to the behaviour of communities exposed to environmental stress may help understand some of the seemingly contrasting findings of past research.Mercator Stiftung via GAMEPostprint4,41

    Feasibility Study of a Reconfigurable Fiber-Wireless Testbed Using Universal Software Radio Peripheral

    No full text
    Fiber-wireless (FiWi) network is still improved ongoingly and there are a number of testbeds for the FiWi network available nowadays. However, most of them are hardware-based, making them not easy to reconfigure to perform architecture or protocol studies. This paper first proposes a reconfigurable FiWi testbed using software-defined radio, particularly universal software radio peripheral (USRP) with LabVIEW as the simulation platform. To evaluate the testbed, wireless range and power output were tested to optimize the best output for the USRP. With the range of 100 m, it was found that the best output power is 30 dB. Then, the study evaluated the performance of the upstream FiWi testbed transmission in terms of throughput, transmission time, and jitter. To test the testbed reconfigurability, the testbed architecture and transmission type were altered, and the performance was scrutinised. The experimental results indicate that USRP is suitable for a reconfigurable FiWi testbed

    A Review of Precast Concrete Beam-to-Column Connections Subjected to Severe Fire Conditions

    No full text
    Fire exposure can have a significant impact on the structural integrity and robustness of precast concrete beam-to-column connections. Given the importance of fire safety in the design of a structure, it is critical to understand the damage that may occur in the event of a fire to be able to prevent the building from collapsing. No comprehensive study has been carried out to determine the effects of fire on semirigid and pinned concrete beam-to-column connections. Most studies focused on the impact of exposure of rigid concrete beam-to-column connections to high temperatures. This paper is a comprehensive review of the literature on the performance of precast concrete beam-to-column connections under fire conditions. The key areas in this review are the moment-rotation-temperature characteristics and fire effect on precast concrete beam-to-column connections. This paper focuses primarily on the case studies of real fires, large-scale fire tests, computer simulations and analytical models, fire resistance tests on the connection elements, and assessment and rehabilitation of fire-damaged precast concrete. The paper also discusses the current issues and possible challenges

    Effect of fibre contents toward manufacturing defects and interfacial adhesion of arenga pinnata fibre reinforced fibreglass/kevlar hybrid composite in boat construction

    In recent years, Arenga Pinnata fibre has been found with great potential to be used as fibre reinforcement in material matrix composites. This study investigates the effect of fibre contents toward manufacturing defects and interfacial adhesion of Arenga Pinnata fibre reinforced Fiberglass/Kevlar hybrid composite material in boat construction. The composite testing coupons were prepared based on the volume fraction of Arenga Pinnata fibre which are 30%, 45%, 60%, and 75%. The long Arenga Pinnata fibre was placed and arranged into the mould by hand lay-up technique. The testing coupon have been arranged with a thickness of 5mm. Manufacturing defects and interfacial adhesion had determined by Scanning Electron Microscopy (SEM) techniques. The SEM results showed that specimen D (60%) of Arenga Pinnata exhibits the less manufacturing defects with a good interfacial and well bonding between the fibre and matrix among other testing specimens. Meanwhile, specimen E (75%) shows the highest manufacturing defects. As a conclusion, 60% of Arenga Pinnata fibre contents showed less manufacturing defects and exhibited good interfacial adhesion. SEM had significantly determined the manufacturing defects and interfacial adhesion of Arenga Pinnata fibre reinforced Fiberglass/ Kevlar hybrid composite material
