Golden Apples or Green Apples? The Effect of Entrepreneurial Creativity on Green Entrepreneurship: A Dual Pathway Model

Entrepreneurs with high creativity (i.e., golden apples) are easy to find, but entrepreneurs with green entrepreneurial intention (i.e., green apples) are rare. To explain this phenomenon, we first introduce cognitive dissonance theory to demonstrate how entrepreneurial creativity influences green entrepreneurship through two parallel mechanisms—green recognition and green disengagement. Moreover, we propose the use of green self-identity as a moderator to predict when the relationships between entrepreneurial creativity and these two mechanisms are intensified or attenuated. Through an empirical study, we surveyed 362 entrepreneurs from a local entrepreneurship association in eastern China. The results show that entrepreneurial creativity is positively associated with both green recognition and green disengagement. While green recognition strengthens green entrepreneurial intention, green disengagement weakens green entrepreneurial intention. More importantly, creative entrepreneurs with high green self-identity are more likely to engage in green recognition and, thus, promote green entrepreneurial intention. By contrast, creative entrepreneurs with low green self-identity are more willing to engage in green disengagement and, thus, inhibit green entrepreneurial intention. Finally, we discuss the theoretical and practical implications of these findings for entrepreneurial creativity and green entrepreneurship.
New records of rodent species in Bangladesh: taxonomic studies from rodent outbreak areas in the Chittagong hill tracts

Rodents are regarded as crop pests, significant reservoirs and vectors for many zoonotic diseases around the world. Basic taxonomic information of rodents present in a locality can help understand which species are responsible as crop pest in that habitat. The phenomenon of the 50-year cycle of gregarious bamboo flowering and rodent outbreaks in the Chittagong Hill Tracts (CHT) of Bangladesh, rodents trapping were carried out in four habitats from March, 2009 to December, 2011 in Ruma upazila of Bandarban hill district. Variety of traps were used to capture small mammals. The captured species were measured and identified using taxonomical dichotomous keys and DNA bar-coding performed in Australia. A total of 14 different small mammalian species were captured of which nine belonging to the Muridae family, and one species each of Spalacidae, Sciuridae, Tupaiidae and Soricidae families. The dominant small mammal species captured were Rattus rattus (54.06%) followed by Mus musculus (26.39%), Rattus nitidus (10.98%), Suncus murinus (5.45%), Mus terricolor (1.09%), Mus cookii nagarum (0.97%), Cannomys badius (0.16%), Leopoldamys edwardsi (0.12%), Berylmys bowersi (0.12%), Vernaya fulva (0.08%), Rattus andamanensis (0.08%), Tupaia glis (0.04%) and Callosciurus pygerythrus (0.04%). Rattus nitidus, Leopoldamys edwardsi, Vernaya fulva, Rattus andamanensis, Berylmys bowersi and Mus cookii nagarum are new records of rodent species in Bangladesh. Ten individuals of Mus spp. (0.40%) were not identified to species level, requiring further genetic analysis to determine their species. The implications of these discoveries are discussed in terms of agricultural pests. Bangladesh J. Zool. 46(2): 217-230, 2018
Experimental study of
 PLA
 thermal behavior during fused filament fabrication

Fused filament fabrication (FFF) is an additive manufacturing technique that is used to produce prototypes and a gradually more important processing route to obtain final products. Due to the layer-by-layer deposition mechanism involved, bonding between adjacent layers is controlled by the thermal energy of the material being printed, which strongly depends on the temperature development of the filaments during the deposition sequence. This study reports experimental measurements of filament temperature during deposition. These temperature profiles were compared to the predictions made by a previously developed model. The two sets of data showed good agreement, particularly con-cerning the occurrence of reheating peaks when new filaments are deposited onto previously deposited ones. The developed experimental technique is shown to demonstrate its sensitivity to changing operating conditions, namely platform temperature and deposition velocity. The data generated can be valuable to predict more accurately the bond quality achieved in FFF parts.
Effect of Fish Offal Meal on Feed Intake, Growth Performances and Carcass Characteristics of Hubbard Classic Broiler Chicken Breeds

The effect of partial substitution of full-fatted soybean poultry meal by fish offal meal in broiler chicks was investigated. The experiment had four treatment diets: diet-1(control, without animal protein); diet-2 (local fishmeal); diet-3 (fermented fish silage); and diet-4 (local tilapia meal). Treatment diets substituted the full-fatted soybean meal in the control diet at 5% level. Unsexed 180, one day old Hubbard Classic broiler chicks were randomly allocated tothe four treatment diets. Treatments had three replications of 15 birds per pen, in a completely randomized design. The experiment has three phases and lasted for 42 days. Overall, feed intake, body weight changes (BWC) and average daily body weight gain (ADG) were significantly (p < 0.05) affected by a diet that diet-1 was lower than fish offal based diets (diets 2, 3, and 4). During the starter period, birds in diet-1 and diet-4 had lower (p<0.05) BWC and ADG than diet 2 and 3. During the finisher period, birds in diet-4 had heavier (p< 0.05) BWC and ADG than diets 1 and 3. There was significantly (p< 0.05) better feed conversion ratio during the finisher period in diet-1 and diet-4 than the rest of the treatments. During the experimental period, higher mortality (p<0.05; 11.1%) was recorded in diet-1 than other diets. Diet-1 was lower in most of the carcass parameters studied. To conclude, regardless of fish species differences, incorporation of fish offal meal into plant-sourced protein diet improves the performance of broiler chicken. In addition, the results indicated that fish silage can also be an alternative to fishmeal.
Peculiarities of PED virus pathogenesis in neonatal non-immune piglets on Ukraine farms

The article presents the results of study of the immune and tissue features of pathogenesis of PED virus in neonatal piglets in Ukraine. Clinical and epizootological analysis was performed in three separate agricultural enterprises with adverse epidemiological situation with PED virus. Blood samples and fragments of the small intestine of PEDv infected piglets were used to study the characteristics of the pathogenesis of PED virus. It has been determined that the pathogenesis of super-acute infection by the PED virus in 1–7 day old non-immune piglets proceeds according to the classic type of infectious process with a relay transmission of the pathogen. Moreover, diarrhea syndrome has induced the development of irreversible and lethal pathophysiological lesions by replication the PED virus in enterocytes of infected piglets. Pathogenetic changes observed in PEDv infected piglets were combined with the following components: acute inflammatory-necrotic process in the tissue of the intestine, destruction and desquamation of the epithelium of the small intestine. The infection process on day 3–5 of manifestation of clinical signs of PED virus is accompanied with an increase in the number of erythrocytes, leukocytes and monocytes, hemoglobin, hematocrit level and aminotransferase activity. In addition, PED virus infection induced an increase in IgM levels and the number of phagocytizing leukocytes with increased aggressiveness and digestive power. The duration of the release of PED virus with feces is 26–37 days after cessation of watery diarrhea. The concentration of PEDv in the feces of convalescent piglets ranged from 120 to 1700 equivalent genome in 1 g of tissue. Parasite coenotic associations of the microbiocenosis of the digestive tract of PED virus infected piglets did not have time to form into stable epitopes. There was a constant quantitative prevalence of transient microbiota and a decrease in the share of probiotic microorganisms. The intestinal microflora consists of random transient microbiota of the environment with pathogenic properties. The results presented show evidence that molecular and cell-mediated immunological events in non-immune piglets have the initial stage of the specific progress of immune response against PEDv.
Receptiveness of effective tax rate to firm characteristics: an empirical analysis on Indian listed firms

Purpose The purpose of this paper is to empirically investigate the factors deriving effective tax rate (ETR) for Indian manufacturing firms in different sectors. The study also tries to analyze the sensitiveness of ETR because of shocks on its key determinants. Design/methodology/approach The study is using Arellano–Bond dynamic panel regression model to identify the key drivers of ETR, and impulse response functions of panel vector auto-regression model to analyze the response of ETR because of one standard deviation (SD) shock to its key determinants. Findings This study concludes that ETR is significantly explained by firm size, profitability, growth rate and non-debt tax shield in most of the sectors, and debt ratio, asset tangibility and age of the firms are impacting ETR differently across sectors. In case of entire manufacturing sector, firm size, profitability, growth and non-debt tax shield are driving ETR positively and asset tangibility is driving ETR negatively. Interest coverage ratio (ICR) and firm age are not significant drivers of ETR. ETR is positively related with firm size, but responses negatively when there is an immediate shock to firm size. Similarly, ETR is negatively related with asset tangibility, but responds positively following an immediate shock to it. Overall, ETR is more sensitive and responses significantly because of shocks in firm size, profitability, growth, asset tangibility and non-debt tax shield whereas, the response is very marginal following shocks to debt ratio, ICR and age of the firm. Research limitations/implications Firm managers may find the study useful to understand the receptiveness of ETRs at each sector level. The empirical findings are not only validating the theoretical developments but also providing a root cause analysis to the firm managers to understand the cause and consequence of ETRs for firms at different sectors. Originality/value Empirically investigating the factors driving ETR and analyzing its sensitiveness because of one SD shock on its key determinants for Indian manufacturing firms from different sectors is the originality of this study. Developing a strong theoretical background and empirically validating it through advanced methodology makes the study unique.
Experimental Investigation of Pedestrian Dynamics in Circle Antipode Experiments

To explore the pedestrian motion navigation and conflict reaction mechanisms in practice, we organized a series of circle antipode experiments. In the experiments, pedestrians are uniformly initialized on the circle and required to leave for their antipodal positions simultaneously. On the one hand, a conflicting area is naturally formulated in the center region due to the converged shortest routes, so the practical conflict avoidance behaviors can be fully explored. On the other hand, the symmetric experimental conditions of pedestrians, e.g., symmetric starting points, symmetric destination points, and symmetric surroundings, lay the foundation for further quantitative comparisons among participants. The pedestrian trajectories in the experiments are recognized and rotated, and several aspects, e.g., the trajectory space distribution, route length, travel time, velocity distribution, and time-series, are investigated. It is found that: (1) Pedestrians prefer the right-hand side during the experiments; (2) The route length follows a log-normal distribution, the route potential obeys an exponential distribution, and travel time as well as speed are normally distributed; (3) Taking the short routes unexpectedly cost pedestrians plenty of travel time, while detours seem to be time-saving.
Open-Ended Problems for Junior High School Students’ Mathematical Reasoning

The abilities that must be mastered by high school students according to the demands of the 2013 curriculum include reasoning. Students who have good reasoning abilities make it easier to understand mathematics. But in reality there are still many students who have low mathematical reasoning ability, seen when they have difficulty solving math problems. This research objective is to prove the habit of solving open-ended problems that can improve the mathematical reasoning ability of junior high school students based on the level of initial mathematical ability: high, medium, and low. The study used an experimental method with a "One-Group pre-test post-test design". Randomly, selected 77 grade VII students of SMP Negeri in Bekasi as a sample. The prerequisite test shows that each level of data comes from groups that are normally distributed and homogeneous. The results showed normal gain, both overall and level showed improvement. Based on the t test obtained p value of 0.000 < 0.005, meaning this study can prove student habits in solving open-ended problems when learning mathematics on triangles and quadrilateral, can improve students' mathematical reasoning abilities.
Quality of Compost Produced from Animal Wastes

The characteristics of animal waste composts produced in Japan were summarized. Animal waste composts are useful for supplying nutrients to plants and for improving the soil properties. The contents of nutrients in the composts were in the order of poultry > swine > cattle. Thus, the effectiveness as fertilizer foll owed the same order. The contents of heavy metals in the animal waste composts were studied. The content of copper was very high in the swine waste composts, and the content of zinc was also high in those from swine and poultry. Such high contents of heavy metals are caused by the addition of these elements to feeds. The objectives of composting were summarized. One of the objectives is to convert the raw animal wastes into products which are easy to handle and safe to health. Another objective is to convert the animal wastes into organic fertilizers which are safe for plant and soil. The maturing process of composting was characterized. Poultry wastes were more easily decomposed than cattle and swine wastes, and the decomposition rate of cattle wastes was almost similar to that of swine wastes. Maturity is an important factor related to the quality of the compost. The detection of nitrate by diphenylamine, the determination of cation-exchange capacity (CEC), and the germination test are recommended as methods of estimating the degree of maturity. Discipline: Soils, fertilizers and plant nutrition/Animal industry Additional key words: degree of maturity, maturing process, nutrients, organic fertilizer, recycling, soil conditioner Along with the enlargement of the scale of livestock farms, the management of wastes has become a serious problem in Japan. From the viewpoints of recycling as resources and prevention of environmental pollution, adequate application of animal wastes to croplands is needed. Animal wastes are very important resources for agriculture, because they contain many nutrients and improve the chemical, physical, and biological properties of soil. However, raw animal wastes are not generally suitable as organic fertilizers or soil conditioners, because they cannot be handled readily and their application to croplands may cause adverse effects on plant and soil. Composting can eliminate the problems to some extent, and is an effective way to promote the agricultural utilization of animal wastes. Quality contro l of the composts is very important to promote the recycling of animal wastes. The qualities required for the utilization of animal waste composts are
Classification of RNA backbone conformation into rotamers using 13C′ chemical shifts: How far we can go?

The conformational space of the ribose–phosphate backbone is very complex as is defined in terms of six torsional angles. To help delimit the RNA backbone conformational preferences 46 rotamers have been defined in terms of the these torsional angles. In the present work, we use the ribose experimental and theoretical 13C′ chemical shifts data and machine learning methods to classify RNA backbone conformations into rotamers and families of rotamers. We show to what extent the use of experimental 13C′ chemical shifts can be used to identify rotamers and discuss some problem with the theoretical computations of 13C′ chemical shifts.
Online feedback and crowdfunding finance in China

This study examines the impact of online feedback on the extent of alternative startups’ fundraising success or failure through reward-based online crowdfunding platforms. By drawing on regulatory focus theory, we theorize that online feedback relating to products or services is crucial in determining the success of entrepreneurial projects. While employing a unique dataset of 620 projects from renowned reward-based Chinese crowdfunding platform “Demohour” (a major pioneer Chinese crowdfunding platform), the findings show a significant effect of online feedback on the extent of success or failure of reward-based crowdfunding campaigns. Our findings, which are robust to different measures and methodologies imply that nascent entrepreneurs need to pay keen attention to online feedback about their innovative projects if they are to be successful in their fundraising efforts.
A natural ancestral saltwater treatment to modify the technological properties of date palms

Les plantations de palmiers phœnix ont une grande importance socio-économique et écologique en Tunisie. Actuellement, elles contiennent près de trois millions d'arbres, qui assurent d'importants approvisionnements en bois pour l'artisanat et l'industrie du meuble. Autrefois, le palmier dattier était également utilisé comme matériau de construction. Ses médiocres propriétés technologiques ont été améliorées par l'immersion dans l'eau salée naturelle des troncs de palmiers fraîchement coupés. C’était une pratique ancestrale dans la zone du Maghreb, mais elle a disparu maintenant, et les informations sur les différents paramètres impliqués dans ce type de processus sont rares. L’objectif de cette étude est d'évaluer les propriétés technologiques principales du bois de Phoenix dactylifera L. quand il est préservé dans l'eau salée. Des échantillons de bois prélevés dans le sud de la Tunisie sur deux cultivars communs de palmier dattier (Kentichi et Deglet Noor) âgés de 40 à 50 ans, non traités et conservés par salage dans le lac Chot Djérid, ont été utilisés pour ces expériences. Les densités, les propriétés mécaniques, la résistance à la putréfaction et aux termites et la composition chimique des échantillons de bois non traités (contrôle) et traités avec l’eau salée ont été déterminés. Les résultats ont montré une augmentation significative de la densité du bois de palmier séché à l'air après immersion dans l'eau salée. Le traitement avec l'eau salée a aussi amélioré le nodule de rupture du bois de palmier phœnix perpendiculairement et parallèlement aux fibres. Les deux, le bois non traité et le bois traité avec de l'eau salée, semblent être sensibles aux agressions de termites, mais le bois de palmier traité semble être plus toxique pour les termites. Les teneurs en extraits de lignine et de cellulose étaient légèrement plus abondantes dans les échantillons témoins, alors que les hémicelluloses étaient plus abondantes dans les échantillons traités. Les analyses minéralogiques ont permis également d'expliquer l'amélioration de la performance du bois de palmier après ce processus de préservation naturelle.
The role of nano-CaCO3 in the mechanical performance of polyvinyl alcohol fibre-reinforced geopolymer composites

ABSTRACT This paper investigates the mechanical (compressive and flexural strengths, flexural rigidity, stiffness, impact strength, hardness, compressive strain-stress and flexural load-deflection) and microstructural properties of polyvinyl alcohol- (PVA)-geopolymer composites reinforced with different amounts of nano-CaCO3 particles and cured at room temperature. The results reveal that using up to 2.0 wt% nano-CaCO3 leads to an improvement in PVA-geopolymer composite performance. Composites with this amount of CaCO3 particles exhibited compact microstructures, as well as high levels of compressive stress-strain and flexural load-deflection, leading to good adhesion or interaction within the PVA fibre interface within the matrix. It was also evident that the combined effect of nano-CaCO3 and well-dispersed PVA fibres in the matrix leads to composites with superior mechanical properties, most clearly in samples containing 2.0 wt% nanoparticles.
In-Vitro Induction of Mutation in Groundnut (Arachis hypogea L.) by Using Sodium Azide Mutagens and Its Impact on Selected Agronomic Traits

Groundnut (Arachis hypogaea L.) is a legume crop belonging to the family Fabaceae. The annual world groundnut production was around 38.2 million tons from 26.4 million ha of production area (FAO, 2012). Groundnut (Arachis hypogaea L.) is an oilseed, food and animal feed all over the world (Pande et al., 2003; Upadhyaya et al., 2006). It is the main source of food in various forms and used as a component of crop rotation in many countries (Gbèhounou and Adengo, 2003). Groundnut is one of the five widely cultivated oilseed crops in Ethiopia (Wijnands et al., 2009). However, it is self-pollinating and possesses limited variability. Consequently, the extent to which groundnut cultivars may be improved through conventional breeding methods is limited.
Optimal arrangement of π-conjugated anionic groups in hydro-isocyanurates leads to large optical anisotropy and second-harmonic generation effect

Birefringent and nonlinear optical (NLO) crystals play indispensable roles in modern optoelectronics and information communication. Hydro-isocyanurates contain π-conjugated building anions [HxC3N3O3]x−3 (x = 0–3) with strong anisotropic first-order polarizability and large second-order susceptibility, and thus they are proposed as an emerging source of birefringent and NLO crystals. Here, we conducted a systematical exploration of alkaline earth-metal hydro-isocyanurates and successfully obtained eight new compounds: Mg(H2C3N3O3)2·8H2O (I), Mg(H2C3N3O3)2·6H2O (II), Ca(H2C3N3O3)2·3H2O (III), α-Sr(H2C3N3O3)2·2H2O (IV), β-Sr(H2C3N3O3)2·2H2O (V), SrHC3N3O3(VI), SrHC3N3O3·2.5H2O (VII) and Ba(H2C3N3O3)2·2H2O (VIII). Most of them possess larger birefringence (>0.24) than commercial ultraviolet birefringent crystals such as calcite (∼0.16). In particular, among all the reported hydro-isocyanurates, acentric VII exhibits a giant NLO effect (d15 = 5 pm V−1) and desirable birefringence (Δn = 0.341 @ 800 nm) to realize a short phase-matching wavelength, due to the optimal arrangement of anionic groups.
