Exploring the impact of entrepreneurial orientation and market orientation on entrepreneurial performance in the context of environmental uncertainty.

In the current complex economic environment, entrepreneurial enterprises, as a crucial force in China's economic transformation, have vital survival and development strategies. This study is grounded in resource-based theory, integrating strategic management and contingency theories. It establishes a theoretical model based on the influence pathway of "entrepreneurial orientation-market orientation-entrepreneurial performance", incorporating environmental uncertainty as a moderating variable.

Modelling of online shopping behavior in the Czech online environment.

The online environment has its own specifics, which shape the specific behavior of all market subjects, both customers and companies that trade electronically. The aim of the paper is to create, quantify and verify a conceptual comprehensive model of relationships between determinants that influence consumers when shopping online. The impetus for the conducted research was the discovery of the non-existence of a comprehensive model of online shopping behavior that reflects the specifics of the online environment.

Who becomes an entrepreneur after university? Evidence from Canada.

In recent decades there has been significant interest among policy makers in supporting entrepreneurship among university students, with the goal to improve labor market outcomes and contribute to the economy through venture creation. Drawing from the 2018 National Graduate Survey in Canada, our study examines who engages in entrepreneurial activity after graduation, investigating differences among demographic groups and between those who participated in entrepreneurship education on campus and those who did not participate. We find that those graduates who participated in entrepreneurship education are more likely to be self-employed and own their own business three years after graduating than the general population of university graduates.

Research on the ordering strategy problem in supply chain with profit allocation under two-level price-fluctuation sales.

Effect of rising fuel prices on small-scale fisheries livelihoods and marine sustainability in Ghana.

This study investigates the effects of fuel price hikes on the livelihoods of small-scale coastal fisherfolk in Ghana. The study applied a mixed-methods approach consisting of a questionnaire survey of 320 fisherfolk and 20 interviews with stakeholders in the fisheries sector. Increase in expenses, reduced frequency of fishing, an upsurge in social vices, and declining small-scale fisheries opportunities were found to be the main effects of fuel price hikes on fisherfolk livelihoods.

An enhanced Transformer framework with incremental learning for online stock price prediction.

To address the limitations of existing stock price prediction models in handling real-time data streams-such as poor scalability, declining predictive performance due to dynamic changes in data distribution, and difficulties in accurately forecasting non-stationary stock prices-this paper proposes an incremental learning-based enhanced Transformer framework (IL-ETransformer) for online stock price prediction. This method leverages a multi-head self-attention mechanism to deeply explore the complex temporal dependencies between stock prices and feature factors. Additionally, a continual normalization mechanism is employed to stabilize the data stream, enhancing the model's adaptability to dynamic changes.

Evaporation Dynamics of Deionized Water Droplets on Hydrophobic Leaves.

Self-cleaning applications based on bionic surface designs requires an in-depth understanding of unique and complex wetting and evaporation processes of sessile droplets on natural biosurfaces. To this end, hydrophobic bamboo and Kalanchoe blossfeldiana leaves are excellent candidates for self-cleaning applications, but various properties, such as the heat and mass transfer processes during evaporation, remain unknown. Here, the dynamics of contact angle, radius, and heat and mass transfer during evaporation of sessile droplets on bamboo and Kalanchoe blossfeldiana leaves with roughness in the range 2.

Elucidating the mechanism behind the significant changes in photoluminescence behavior after powder compression into a tablet.

Nonconventional luminogens have great potential for applications in fields like anti-counterfeiting encryption. But so far, the photoluminescence quantum yield (PLQY) of most of these powders is still relatively low and the persistent room temperature phosphorescence (p-RTP) emission is relatively weak. To improve their PLQY and p-RTP, pressing the powder into tablets has been preliminarily proven to be an effective method, but the specific mechanism has not been fully elucidated yet.

Volatile Profile of Bee Pollens: Optimization of Sampling Conditions for Aroma Analysis, Identification of Potential Floral Markers, and Establishment of the Flavor Wheel.

Pesticide safety behavior among vegetable farmers in Bangladesh: Evaluating the role of market aggregation services.

Pesticide use in Bangladesh is disproportionately high in vegetable farming compared to other crops like cereals, pulses, and cash crops. This study delves into the knowledge, attitudes, and practices regarding pesticide use among vegetable farmers, focusing on the impact of a digital aggregation service implemented by Digital Green. Based on interviews with 120 vegetable farmers in the LOOP aggregation scheme and 120 non-LOOP vegetable farmers this study indicates that the farmers using the aggregation service have a moderately higher level of food safety knowledge.

Effects of ORF14 gene on melanin expression, fermentation conditions and properties of melanin production in modified strains.

Melanin with antioxidant and antibacterial properties can be used in food, cosmetics, biotechnology, and other fields, but its insolubility become a main challenge hindering for its application. In this study, water-soluble melanin produced by the novel species Streptomyces vilmorinianum YP1 was characterized using scanning electron microscopy (SEM), UVvisible spectroscopy (with an absorption peak at 220 nm), and Fourier transform infrared (FTIR) spectroscopy. The glycosyltransferase gene ORF14 was knocked out, which improved the production of water-soluble melanin by inhibiting competitive pathway.

Examining Truth Regimes Reveals How Local Communities View Flooding and River Management in the Lower Missouri River Basin, USA.

Riverine flooding is increasing in frequency and intensity, requiring river management agencies to consider new approaches to working with communities on flood mitigation planning. Communication and information sharing between agencies and communities is complex, and mistrust and misinformation arise quickly when communities perceive that they are excluded from planning. Subsequently, riverfront community members create narratives that can be examined as truth regimes-truths created and repeated that indicate how flooding and its causes are understood, represented, and discussed within their communities-to explain why flooding occurs in their area.
