Research on the Differentiated Impact Mechanism of Parent Company Shareholding and Managerial Ownership on Subsidiary Responsive Innovation: Empirical Analysis Based on ‘Principal–Agent’ Framework
Authors: Xu Peng , Zhang Heng , Bai Guiyu
Published: September 2019

Under the dynamic competition situation, the innovation competition interaction between enterprises will take the form of mutual responding, while the formulation and implementation of responsive innovation strategy will be influenced by both shareholders and managers in the principal–agent relationship. In our research, we try to understand how the difference of governance logic between shareholders and managers affects innovation interaction strategy of enterprises. In order to achieve this research goal, this study takes all eligible listed companies (from 2007 to 2016) in China’s stock market as samples. The results show that the parent company shareholding has a negative impact on the subsidiary responsive innovation, while companies whose managers hold more shares select the relatively positive strategy responsive innovation. Moreover, the degree of separation between ownership and control rights and the external institutional environment can moderate the above relationship. Relevant conclusions can provide some reference value for the formulation of responsive innovation decision of listed companies and provide new insights for the design of parent–subsidiary corporate governance structure and the design of managerial equity incentive mechanism in the context of corporate group governance.
Factors Influencing Social Perception of Residential Solar Photovoltaic Systems in Saudi Arabia
Authors: Alrashoud Khalid , Tokimatsu Koji
Published: September 2019

Saudi Arabia has taken major steps to shift from an oil-centered to more environmentally-focused economy. One approach made recently is to enable households to possess and generate electricity by using small-scale residential solar photovoltaic systems (RSPSs). However, the number of applications to install this technology in residences is significantly low. Social acceptance of solar energy is essential for a successful energy transition. Hence, the present study aims to examine factors that may potentially motivate or impede individuals from purchasing RSPSs based on the diffusion of innovations theory. A cross-sectional, web-based survey is conducted including 1498 participants from the five main regions of Saudi Arabia. Results revealed a good cognition level in relation to solar energy, where the majority (64–83%) of respondents are aware of the benefits. An overwhelming proportion of the respondents (97%) associate RSPSs with a significantly positive image, with no significant variation in the acceptance or rejection rates among the five areas covered by the survey (p = 0.1). The results also show high statistical significance for the differences between RSPS acceptors and rejecters in all innovation attributes (p < 0.001). However, the perception of relative advantage has a higher correlation with acceptance RSPSs. These perceived advantages were of rather long-term nonfinancial benefits, such as environmental protection against global warming and provision of unlimited power, rather than the revenue related to direct costs benefits. The study also revealed that the installation cost was the most significant barrier to adopting the RSPS, which can be a focus for RSPS dissemination policies.
The Role of Renewables in a Low-Carbon Society: Evidence from a Multivariate Panel Data Analysis at the EU Level
Authors: Busu Mihail
Published: September 2019

Low carbon emission has a major positive impact on our society. Due to the importance of reducing carbon emission levels, factors that contribute significantly towards reducing carbon emission levels have attracted the interest of academics and researchers in the field. In this paper, the author develops a multiple linear regression analysis to examine the relationship between renewable energy consumption, biofuel production, resources productivity, bioenergy productivity, the level of urbanization and population and their impact on total carbon dioxide (CO2) emissions. Data was collected from the European Statistical Office (EUROSTAT) and four statistical hypotheses were validated through a regression model with panel data using the statistical software EViews 11. The study was conducted for 27 European Union (EU) countries during 2008 to 2017. The author’s findings indicate that renewables have a direct and positive influence on the levels of CO2 emissions, as opposed to population growth and urbanization. These findings suggest that public policy should be directed towards increasing the use of renewables in EU countries, while the level of urbanization and the population growth add more restrictions in the modelling equation of the impact on CO2 emissions.

Published: September 2019

This study aimed to analyze the characteristics of bicycle–passenger conflicts at bus stops and develop a model to predict the number of conflicts accurately. This paper investigated the traffic flow operation at bus stops by video recording. Duration and distribution characteristics of bicycle–passenger conflicts were statistically analyzed. Then four types of conflicts defined based on evasive behavior (cyclist yielding as Type 1, cyclist bypassing as Type 2, passenger yielding as Type 3, and passenger bypassing as Type 4) were compared. A generalized event count (GEC) model was established for bicycle–passenger conflict estimation and analysis. The main results indicated that: (1) The average conflict duration was 1.716 s, whilst 60.9% of conflicts existed near the accesses of bus stops in longitudinal direction; (2) Type 1 conflict was significantly different from Type 2, 3, and 4 conflicts in duration, whilst the three had no significant difference; (3) the proposed GEC model showed good performance in predicting bicycle–passenger conflicts, with 15.71% of mean-absolute-percentage-error and 0.8772 of R2; and (4) bicycle volume, bus passenger volume, and passenger crossing time were critical factors impacting the number of bicycle–passenger conflicts. Finally, transport agencies may consider installing separations and crosswalks to improve the safety of the stop area.
Experimental Study on the Performance of an Innovative Tide-Induced Device for Artificial Downwelling
Authors: Fan Wei , Pan Dongdong , Xiao Canbo , Lin Tiancheng , Pan Yiwen , Chen Ying
Published: September 2019

Hypoxia has been increasingly observed in estuaries and coastal marine ecosystems around the world. In this paper, a tide-powered artificial downwelling device is proposed to potentially alleviate hypoxia in bottom waters. The downwelling device mainly consists of a vertical square tube, a 90° bend sitting on the top of the tube, two symmetrical-guide plates which installed alongside the vertical tube, a static mixer, and an artificial reef. Scale model experiments are performed with respect to different density difference heads, horizontal current velocities, and tube geometries. The results show that the downwelling flow rate is dependent on horizontal current velocity, tube geometry parameters, and the density profile of ambient water. In addition, increasing the equivalent diameter and bend radius of the device can decrease the total loss coefficient in the tube, which in turns enhance the downwelling efficiency. The two symmetrical-guide plates also generate obvious downwelling of surface water which further improves the whole performance of the device. Further work will need to determine the influence of the other parts of the device, such as the static mixer and artificial reef, on the downwelling efficiency.
From Transition to Domains of Transformation: Getting to Sustainable and Just Food Systems through Agroecology
Authors: Anderson Colin Ray , Bruil Janneke , Chappell Michael Jahi , Kiss Csilla , Pimbert Michel Patrick
Published: September 2019

The acceleration of ecological crises has driven a growing body of thinking on sustainability transitions. Agroecology is being promoted as an approach that can address multiple crises in the food system while addressing climate change and contributing to the Sustainable Development Goals. Beyond the more technical definition as, “the ecology of food systems”, agroecology has a fundamentally political dimension. It is based on an aspiration towards autonomy or the agency of networks of producers and citizens to self-organize for sustainability and social justice. In this article, we use the multi-level perspective (MLP) to examine agroecology transformations. Although the MLP has been helpful in conceptualizing historic transitions, there is a need to better understand: (a) the role of and potential to self-organize in the context of power in the dominant regime, and (b) how to shift to bottom-up forms of governance—a weak point in the literature. Our review analyzes the enabling and disabling conditions that shape agroecology transformations and the ability of communities to self-organize. We develop the notion of ‘domains of transformation’ as overlapping and interconnected interfaces between agroecology and the incumbent dominant regime. We present six critical domains that are important in agroecological transformations: access to natural ecosystems; knowledge and culture; systems of exchange; networks; discourse; and gender and equity. The article focuses on the dynamics of power and governance, arguing that a shift from top down technocratic approaches to bottom up forms of governance based on community-self organization across these domains has the most potential for enabling transformation for sustainability and social justice.
Is Super-Intensification the Solution to Shrimp Production and Export Sustainability?
Authors: Nguyen Tram Anh Thi , Nguyen Kim Anh Thi , Jolly Curtis
Published: September 2019

The government of Vietnam has selected shrimp production and exports as the pillars of rural economic development. The targets set depend on high yields through production intensification. International and national public research communities have raised production intensification concerns related to environmental and climate change challenges, such as saltwater intrusion, water pollution, disease outbreaks, mangrove destruction, and natural resource degradation. Social snags such as user right conflicts of water resources, food safety problems, tariff barriers, and attempts to taint the industry’s image by competitors also plague the industry. These give rise to the problem of certification and questions about the influence of standards on the small-scale farming sustainability in a competitive global environment. The questions asked are, how can one bring together small-scale shrimp farmers to comply with international standards? Can small-scale shrimp farming co-exist with super-intensive producers to bring about a sustainable and competitive industry? A proposed model to horizontally organize the limited resource farmers into cooperatives to vertically integrate with large-scale firms producing shrimp using super-intensive production methods shows small-scale farmers adopting super-intensive production methods that can generate higher yields, income, profits, and is more environmentally friendly and requires less water and land. The capital requirements are high for limited resource farmers. However, with the interest showed by banks in financing models that are appropriate for small-scale farms integrated with larger firms engaged in super-intensive production systems, along with government assistance, these small-scale shrimp producing units can attain higher levels of sustainability than the open, less intensive production systems.

Published: September 2019

A sustainable and environmentally friendly society is developing rapidly, in which pavement engineering is an essential part. Therefore, more attention has been paid toward waste utilization and urban noise pollution in road construction. The object of this study was not only to investigate the mix proportion of waste crumb modified asphalt mixtures with diatomite and basalt fiber but also to evaluate the comprehensive performances including sound and vibration absorption of modified asphalt mixtures. Firstly, the mix proportion scheme was designed based on Marshall indices and sound and vibration absorption properties according to the orthogonal experimental method. Considering the specification requirements, as well as better performances, the optimal mix proportion was determined as follows: diatomite content at 7.5%, basalt fiber content at 0.3%, and asphalt-aggregate ratio at 5.5%. The range and variance analysis results indicated that asphalt-aggregate ratio has the most significant influence on volumetric parameters, diatomite has the most significant influence on sound absorption, and basalt fiber has the most significant influence on vibration reduction. Furthermore, the conventional pavement performances and sustainable sound and vibration absorption performances of modified asphalt mixtures were also analyzed. The results showed that the performances of modified asphalt mixtures were improved to different extents compared to the base asphalt mixture. This may be attributed to the microporous structure property of diatomite and the spatial network structure formed by basalt fibers. The pavement as well as sound and vibration absorption performances of the waste crumb modified asphalt mixture with diatomite and basalt fiber would be a good guidance for asphalt pavement design.

Published: September 2019

Phosphorus is a biogenic element with a high importance within the food chain. Regrettably, there are limited amounts of phosphorus within minerals naturally occurring in the environment. Its scarcity leads to a necessity of closed loop economy, where this element could be obtained by the processing of various waste materials. Modern agriculture needs to provide sufficient amounts of phosphorus to plant organisms encountering problems with the bioavailability of nutrition. In this research, a post-processed animal waste material (calcined bone) was utilized to reclaim phosphorus and reintroduce it into the environment in a form of foliar fertilizer. The calcined bones were subjected to chemical transformation with nitric acid solution. The solubilization of bones was followed by laboratory-scale pot experiments, in which the fertilizer was used for the cultivation of maize plants. In the field experiments, the fertilizer was additionally fortified with boron and molybdenum elements. It was observed that the utilization of the fertilizer had a positive impact on maize plants, i.e., improvement in the biomass production of aboveground and underground parts of the plants. The amount of chlorophyll increased in comparison to control plants. Maize grain production was increased by approximately 600 kg ha−1).
A System Dynamics Modeling Support System Based on Computational Intelligence
Authors: Abdelbari Hassan , Shafi Kamran
Published: September 2019

System dynamics (SD) is a complex systems modeling and simulation approach with wide ranging applications in various science and engineering disciplines. While subject matter experts lead most of the model building, recent advances have attempted to bring system dynamics closer to fast growing fields such as data sciences. This may prove promising for the development of novel support methods that augment human cognition and improve efficiencies in the model building process. A few different directions have been explored recently to support individual modeling stages, such as the generation of model structure, model calibration and policy optimization. However, an integrated approach that supports across the board modeling process is still missing. In this paper, a prototype integrated modeling support system is presented for the purpose of supporting the modelers at each stage of the process. The proposed support system facilitates data-driven inferring of causal loop diagrams (CLDs), stock-flow diagrams (SFDs), model equations and the estimation of model parameters using computational intelligence (CI) techniques. The ultimate goal of the proposed system is to support the construction of complex models, where the human power is not enough. With this goal in mind, we demonstrate the working and utility of the proposed support system. We have used two well-known synthetic reality case studies with small models from the system dynamics literature, in order to verify the support system performance. The experimental results showed the effectiveness of the proposed support system to infer close model structures to target models directly from system time-series observations. Future work will focus on improving the support system so that it can generate complex models on a large scale.

Authors: Sabiá Júnior Elias Ferreira , Menezes Luis Felipe Santos , de Araújo Israel Flor Silva , Schwartz Elisabeth Ferroni
Published: September 2019

Arthropoda is a phylum of invertebrates that has undergone remarkable evolutionary radiation, with a wide range of venomous animals. Arthropod venom is a complex mixture of molecules and a source of new compounds, including antimicrobial peptides (AMPs). Most AMPs affect membrane integrity and produce lethal pores in microorganisms, including protozoan pathogens, whereas others act on internal targets or by modulation of the host immune system. Protozoan parasites cause some serious life-threatening diseases among millions of people worldwide, mostly affecting the poorest in developing tropical regions. Humans can be infected with protozoan parasites belonging to the genera Trypanosoma, Leishmania, Plasmodium, and Toxoplasma, responsible for Chagas disease, human African trypanosomiasis, leishmaniasis, malaria, and toxoplasmosis. There is not yet any cure or vaccine for these illnesses, and the current antiprotozoal chemotherapeutic compounds are inefficient and toxic and have been in clinical use for decades, which increases drug resistance. In this review, we will present an overview of AMPs, the diverse modes of action of AMPs on protozoan targets, and the prospection of novel AMPs isolated from venomous arthropods with the potential to become novel clinical agents to treat protozoan-borne diseases.

Effect of Irrigation on the Yield and Quantity of Potato Varieties
Authors: Ábrahám Babett Éva , Sárvári Mihály
Published: September 2019

In Hungary, the growing area of potato area dropped dramatically in the last few decades. Additionally not only are we lagging behind Western European countries as regards yields, but the competitiveness of production is further decreased by the great alternation in yields from year to year, unpredictable market conditions, poor consumption habits and, often the lack of quality products.The experiment was carried out at the experimental site of the University of Debrecen, Farm and Regional Research Institute, at Látókép. In our experiment, we examined the yield and some quality parameters of 9 medium-early varieties in large parcels. Of the examined varieties, 3 are of Dutch, and 6 are of Hungarian breeding.The experiment was set up in 2003 and 2004, in two years of significantly different precipitation, on 50 m2 parcels on calcareous chernozem soil after winter wheat as a forecrop in both years. The 9 varieties were examined in 4 repetitions in randomized blocks, from which two repetitions were irrigated, and two were non-irrigated.We examined the yields of the varieties, the distribution of tubers according to size and their percentages, and the changes in specific parameters of quality and inner content due to irrigation. We studied the dry matter content, the starch content, the underwater mass, the amount of reducing sugars, and the colour index of frying of the tubers.In Summary, it can be stated that among the agrotechniques, year effect, variety and irrigation factors have considerable impact on potato yield quality and quantity. However the effect of irrigation depends on the crop year. In a draughty year, like in 2003, irrigation could increase the yield by 10%, while in a more favourable wet year, the improving effect of irrigation was low.

Published: September 2019

Spatial problems and spatial decisions are decisive in agricultural-environmental informatics systems and the solutions require systems that can collect, evaluate and display spatial data. The distinctive features of spatial informatics systems therefore have to be considered when establishing integrated spatial informatics systems.However, the prepared spatial evaluations are not the only „added value” elements of a completed informatics system. The method of access can also speed up the work of participants and the whole system, making it more efficient with simple data-handling and the application of open standards. The significance of prepared database archives can also increase, since the accumulated data-assets are easy to utilize and become marketable.

Crime is an unplanned change due to the process of urban development. The geographical approach is able to analyze spatial interactions of criminogenic factors into crime phenomenon. This study aims to explain the spatial interaction between socio-economic conditions and crime risk in Bandung City. The crime risk is obtained through Kernel Density Estimation (KDE) method based on The Annual Crime Data from Bandung Police Department, whereas the socio-economic condition data is revealed from interview and questioner with 176 respondents who determined by multistage random sampling in 37 hamlets. Variable interactions are analysed based on Geographically Weighted Regression (GWR) with Gaussian Distance Function type of cross validation as optimum weight. The results show the socio-economic conditions has a positive and significant effect on crime risk. This model shows that the independent variable acts as a crime attractor. Partially its known that economic conditions have a stronger interaction with crime risk than the social climate. The strongest interaction between variables are concentrated in the southern of Kebon Pisang Urban Village, precisely in the area passed by arterial roads at southern of Sumur Bandung. Crime prevention efforts are conducted using environmental interventions by the formal security personnels and strengthening the social climate of the community.
Teachers' beliefs about technology integration in early childhood education: A meta-ethnographical synthesis of qualitative research
Authors: Mertala Pekka
Published: September 2019

There is a body of evidence suggesting that instead of concentrating only on teaching and learning (the education task), teachers believe that their tasks are to care for their students social, emotional, and physical needs (the caring task), and to raise them to be and become functional members of society (the socialization task). However, this diversity has not been acknowledged in teachers' beliefs research done in technology integration context. To provide a more nuanced understanding of the variety and role of teachers' beliefs about technology integration this study has synthesized 35 qualitative empirical research studies via the method of meta-ethnography. The focus is on early childhood education (ECE) as so far, no reviews on early childhood teachers' beliefs have been conducted. The synthesis suggests, that education, socialization, and care all have a meaningful role in teachers' beliefs towards technology use in ECE. Each of these tasks and dimensions were identified from teachers' beliefs for or against integrating technology into ECE practices. The synthesis also suggests, that teachers’ beliefs are shaped by macro- and micro-contextual factors including national educational policies and personal experiences. Implications for teacher education are discussed.

Hash functions are modern cryptography that have been developed by cryptographers to make security applications for protecting the integrity of data. However, almost all hash functions are either unsecure or inefficient. Therefore, another better hash function is needed to be used as an alternative hash function. In this paper, authors aim to re-explore message digest algorithms then proposes a new hash function was developed to combine the optimized internal strength elements of the algorithms, namely MD5 and SHA-1 to obtain a basic operation of the new hash that overall enhance the security, but still efficient. The proposed new hash function has been evaluated and the results shown that its execution time are slightly shorter than the combination of (SHA-192+MD5) but almost as fast as with the combination of (SHA-1+MD5). In addition, its avalanche effects exceeds 50% (the ideal condition is around 50%). These are secure enough for security applications.

The purpose of this study was to examine the differences in sensitivity of three methods: IRT-Likelihood Ratio (IRT-LR), Mantel-Haenszel (MH) and Logistics Regression (LR), in detecting gender differential item functioning (DIF) on National Mathematics Examination (Ujian Nasional: UN) for 2014/2015 academic year in North Sumatera Province of Indonesia. DIF item shows the unfairness. It advantages the test takers of certain groups and disadvantages other group test takers, in the case they have the same ability. The presence of DIF was reviewed in grouping by gender: men as reference groups (R) and women as focus groups (F). This study used the experimental method, 3x1 design, with one factor (i.e. method) with three treatments, in the form of 3 different DIF detection methods. There are 5 types of UN Mathematics Year 2015 packages (codes: 1107, 2207, 3307, 4407 and 5507). The 2207 package code was taken as the sample data, consisting of 5000 participants (3067 women, 1933 men; for 40 UN items). Item selection was carried out based on the classical test theory (CTT) on 40 UN items, producing 32 items that fulfilled, and item response theory selection (IRT) produced 18 items that fulfilled. With program R 3.333 and IRTLRDIF 2.0, it was found 5 items were detected as DIF by the IRT-Likelihood Ratio-method (IRT-LR), 4 items were detected as DIF by the Logistic Regression method (LR), and 3 items were detected as DIF by the Mantel-Haenszel method (MH). To test the sensitivity of the three methods, it is not enough with just one time DIF detection, but formed six groups of data analysis: (4400,40),(4400,32), (4400,18), (3000,40), (3000,32), (3000,18), and generate 40 random data sets (without repetitions) in each group, and conduct detecting DIF on the items in each data set. Although the data lacks model fit, the 3 parameter logistic model (3PL) is chosen as the most suitable model. With the Tukey's HSD post hoc test, the IRT-LR method is known to be more sensitive than the MH and LR methods in the group (4400,40) and (3000,40). The IRT-LR method is not longer more sensitive than LR in the group (4400,32) and (3000,32), but still more sensitive than MH. In the groups (4400,18) and (3000,18) the IRT-LR method is more sensitive than LR, but not significantly more sensitive than MH. The LR method is consistently tested to be more sensitive than the MH method in the entire analysis groups.

This research is aimed at finding a sustainable alternate source of energy that can be used as a substitute for conventional fuel sources, which are fast dwindling towards the point of exhaustion. Bio-diesels are viewed as an effective alternate source of energy which can be better than conventional fossil fuels in its performance, combustion and greenhouse gas emission rates. The oil of rice bran methyl ester is used for experimentation. The oil is blended in different ratios with pure diesel in a process known as blending. The various blends are then subjected to performance test in a diesel engine. The biodiesel blends have also been tested for emission properties with and without exhaust gas recirculation. The results reveal that rice bran biodiesel emits less amount of carbon monoxide emissions.

For many years, English Language Teaching (henceforth ELT) in Indonesia has adopted a monolithic view toward the so-called ‘native speaker English’ as an ideal target language. However, this view has been challenged by the pluralistic view of English. Sociolinguistics realities indicate the plurality of the English language has grown enormously around the world. In term of English proficiency, this notion is made more complicated in the absence of any unitary framework and by the diverse meanings arising from in its use as a global language. The aim of this study is to identify the attributes of ‘Proficiency in English’ which suits with the local needs for the Indonesian context in today’s world. To this end, the personal constructs of a small number of English teachers were explored and identified. A Repertory Grid interview technique was used to elicit the meanings of ‘Proficiency in English’ which were based on the teachers’ understanding. For analyzing the qualitative data, a thematic analysis was employed to formulate the themes. These teachers of English revealed that they perceived ‘Proficiency in English’ comprising knowledge of English and abilities to apply it in real situations. Surprisingly, they also declared that to be proficient in English, one should have intercultural competence and employ it for the intercultural and cross-cultural communications internationally which has been advocated by the English as an International language (henceforth EIL) perspective. The findings of this study could be used to inform ELT program and its practices in the Indonesian context.
