    The Effect of Knowledge Decomposability on Technological Exploration in Technological Acquisitions
    Li, Z ; Duysters, G ; Gilsing, V (Academy of Management, 2017)
    We investigate the effect of the acquiring firm’s knowledge-base decomposability on its post-acquisition technological exploration. We develop arguments to explain how organizational variations in a firm’s capability to understand the interdependencies between internal knowledge elements affect the generation of exploratory technologies from technological acquisitions. We also examine how the malleability and size of the acquired knowledge base compensate the magnitude of this effect. Our findings suggest that firms with a moderate understanding of the interdependencies between internal knowledge elements (i.e., with a near-decomposable knowledge base) generate the most exploratory technologies from technological acquisitions. We also find that the magnitude of this effect can be enhanced by acquiring knowledge bases with higher malleability, or with a larger size.

    Family Structure and Peasants Entrepreneurship: Empirical Analysis Based on CTVS Data
    Yang, C ; He, X ; Li, Z (China Industrial Economics Press, 2017)
    Many scholars explore rural entrepreneurship behavior from the perspective of individual traits and external environment. In fact, rural entrepreneurship behavior is deeply influenced by family factors. How family structure affects rural entrepreneurship behavior is still an unexplored research question. Based on family capital theory and by using data of Chinese Thousand Village Survey (CTVS) in 2016, this paper tries to figure out the relationship between families structure and rural entrepreneurship, and gets the following conclusions. 1. The elite background of rural family, ie. family member holding village cadre title, being a party member, or regarded as respectable person, will significantly improve the peasant’s entrepreneurial activities; while as soon as the family structure is broken, ie. Divorce, disability of siblings, kids or parents, will significantly decrease the possibility of peasant’s entrepreneurial activities. 2. Peasants in elite families are more inclined to choose opportunity-oriented entrepreneurship, and those in disintegration families are more inclined to choose survival-oriented entrepreneurship. 3. The regional GuanXi culture plays a significant moderating role between elite family and peasants’ entrepreneurial behavior. Peasants in elite families are more inclined to start new business in the areas with strong GuanXi culture. This paper analyses the internal mechanism of Chinese rural entrepreneurial behavior in economic transition period, which can help to explore the family factors and their mechanism of encouraging peasants’ entrepreneurial behavior. It has a theoretical contribution to promote the new development of rural entrepreneurship theory paradigm.

    Aortic Elastic Properties and Myocardial Performance Index Are Impaired in Patients with Lichen Planus.
    Koseoglu, C ; Erdogan, M ; Ertem, AG ; Koseoglu, G ; Akoglu, G ; Aktas, A ; Ozdemir, E ; Kurmus, O ; Durmaz, T ; Keles, T ; Bozkurt, E (S. Karger AG, 2016)
    OBJECTIVES: The aim of this study was to investigate the elastic properties of the aorta and the myocardial performance index of the left ventricle (LV) in patients with lichen planus (LP). SUBJECTS AND METHODS: A total of 54 patients with LP and 50 controls were enrolled in the study. The 2 groups were well-matched regarding age, gender, body mass index, any smoking history, diabetes mellitus and systolic and diastolic blood pressure (SBP and DBP). The echocardiographic examination was performed on the study subjects and the controls. Aortic elasticity parameters and the myocardial performance index of the LV were calculated. The Student t test, the x03C7;2 test and multiple linear regression were used for the statistical analysis. RESULTS: Aortic strain (AS, 4.77 ± 1.81 vs. 8.95 ± 2.22; p < 0.001) and aortic distensibility (AD, 0.25 ± 0.009 vs. 0.42 ± 0.120; p < 0.001) were significantly lower, and aortic stiffness index β (ASIβ, 3.65 ± 1.03 vs. 2.70 ± 0.91; p < 0.001) was significantly higher in the LP group than in the controls. The myocardial performance index (Tei index) was significantly higher in the LP group than in the control group (p = 0.001). The duration of the LP was negatively correlated with AS (r = -0.364, p < 0.001) and AD (r = -0.279, p = 0.006), and positively correlated with the Tei index (r = 0.324, p = 0.001) and ASIβ (r = 0.364, p < 0.001). After adjustment for relevant confounders (age, male gender, smoking, SBP, DBP, diabetes mellitus and low- and high-density lipoprotein cholesterol), LP and its duration were still associated with AS, AD and ASIβ. CONCLUSION: In this study, AS and AD were lower and ASIβ and myocardial performance index higher in LP patients than in controls.

    Imagining better societies: A social psychological framework for the study of utopian thinking and collective action
    Badaan, V ; Jost, JT ; Fernando, J ; Kashima, Y (Wiley, 2020-01-01)
    We present an integrative theoretical model that specifies social psychological mechanisms by which utopian thinking, which activates the social imagination, may enhance collective action intentions oriented toward social change and human progress. The model synthesizes complementary insights from interdisciplinary research programs on utopianism, hope, construal level, and system justification to identify mechanisms by which imagining better societies: (a) increases social hope, (b) yields an abstract mindset that bridges the psychological distance between the status quo (“here and now”) and a better possible future, (c) decreases system justification motivation, and (d) promotes social justice-oriented forms of collective action.

    Comparative assessment of embodied energy of recycled aggregate concrete
    Wijayasundara, M ; Crawford, RH ; Mendis, P (Elsevier, 2017)
    Concrete waste can be recycled to produce an aggregate product; referred to as recycled concrete aggregate (RCA). While RCA is mainly used as a road base filler material, it has the potential to replace natural coarse aggregate (NA) in structural concrete. In determining the environmental performance of the resultant concrete product from this substitution, referred to as recycled aggregate concrete (RAC) against its counterpart, natural aggregate concrete (NAC), it is important to consider the effects of the entire life cycle including the upstream processes associated with each. This paper evaluates “cradle-to-gate” embodied energy (EE) of RAC received at a construction site, in comparison to NAC, using the input-output-based hybrid approach, using an Australian context. The paper constructs a model to evaluate EE of RAC and analyses the incremental energy of RAC as opposed to NAC, to identify what contribute to the difference out of four primary factors discussed in previous research. It was found that the EE of RAC is marginally different to that of NAC by +2.1 to −1.1%, and the variation was subject to the magnitude and direction of the four factors considered. The mix composition, primarily the binder composition, was found to have the highest contribution to the difference, significantly standing out from the direct energy difference between RCA and NA, difference of sourcing distance between RCA and NA and the difference of direct manufacturing energy between RAC and NAC.

    Methodology for the integrated assessment on the use of recycled concrete aggregate replacing natural aggregate in structural concrete
    Wijayasundara, M ; Mendis, P ; Crawford, RH (Elsevier, 2017)
    Recycled concrete waste in the form of recycled concrete aggregate (RCA) is presently used mostly as a road base filler in Australia. However, instead of producing natural aggregate (NA) to manufacture natural aggregate concrete (NAC) to use in structural concrete, there is potential to use RCA to manufacture recycled aggregate concrete (RAC). While the material performance of RAC compared to NAC is analysed in the existing literature, it is not evident whether the use of RCA in structural concrete results in financial and environmental benefits. Previous literature analysing these aspects mostly focuses on a single area of investigation. This paper presents an integrated methodology for the assessment of the use of RCA replacing NA in structural concrete, considering technical, financial, environmental and social perspectives. Cost-benefit assessment (CBA) has been used to evaluate the internalised impacts as well as external costs concerning the use of both RAC and NAC. The scope of each discipline-focused assessment is presented demarcating the relevant scope for further study, and the specific tools and methodologies to be adopted are specified. Finally, amalgamating the different discipline-focused assessments, a unique approach for comparing a sustainable, alternative raw material for concrete, is presented in this paper.

    Integrated assessment of the use of recycled concrete aggregate replacing natural aggregate in structural concrete
    Wijayasundara, M ; Mendis, P ; Crawford, RH (Elsevier, 2018)
    The use of recycled concrete aggregate (RCA) replacing natural aggregate (NA) to produce concrete named as recycled aggregate concrete (RAC) has gained increased importance in the last few decades. Despite many visible advantages associated with the initiative, RAC is not manufactured at commercial scale to replace natural aggregate concrete (NAC) used as structural concrete in Australia presently. To identify whether the production of RAC should be favoured against NAC, an integrated assessment combining multiple criteria is essential as the previous research findings provide mixed outcomes on financial viability, product performance and environmental performance. This paper uses an integrated assessment methodology employing cost-benefit analysis (CBA) which combines the financial, direct and indirect environmental, social outcomes associated with the initiative to evaluate its suitability. By combining several qualitative and quantitative studies published by the author/s, an integral result to compare the use of RCA replacing NA in structural applications is conducted in this study. Net present value (NPV) to society associated with a unit volume of RAC is evaluated as a representative indicator to compare RAC against NAC in this paper. The results state that a unit volume of RAC results in a positive NPV of 4.2–6.0% of the price of NAC for 30% replacement (and 16.3–22.6% for 100%), prior to being used in a building r. Simulation of application of the RAC to two case study buildings indicate that the average price of concrete used in the buildings is decreased by 4.1–6.1%. The results indicate that, if the external benefit associated with the production of RAC is internalised and passed on to the purchaser of the product, production of RAC in structural buildings result in a positive NPV and saving of building material costs to the contractor.

    Net incremental indirect external benefit of manufacturing recycled aggregate concrete
    Wijayasundara, M ; Mendis, P ; Crawford, RH (Elsevier, 2018-08-01)
    Concrete waste (CW) either reaches landfill with mixed waste or crushed to produce crushed concrete (CC) used as a road-base product in Australia. The coarse portion of CC, referred to as recycled concrete aggregate (RCA) has the potential to be used as an aggregate in structural concrete replacing natural aggregate (NA). The environmental performance of RAC has been studied in comparison to NAC, in terms of direct environmental implications (DEI) concerning the processes in the production chain of these products. However, when replacement at industry level is considered, the implications go beyond the DEI, and affect a series of other products/processes within a system boundary, referred to as indirect environmental implications (IEI). This paper quantifies the key IEI associated with the use of RCA in structural concrete and evaluates the external costs and benefits associated with it using economic evaluation methods. The net benefit associated with the avoidance of landfill of CW, extraction of NA, and transportation of waste and by-products are the major externalities identified and quantified in this paper. Evaluation of these suggest that there is a significant net benefit ranging from 9% to 28% of the price of natural aggregate concrete (NAC) with the production of recycled aggregate concrete (RAC), for RCA replacement rates between 30% and 100%.
