This study examines the impact of college education on incorporated and unincorporated self-employments. It specifically compares the effects on African Americans and Hispanics with the effects on Whites.

The study sample was drawn from the US Current Population Survey between 1989 and 2018. Based on a sample size of 1,657,043 individuals, this study employed logit regression models to test the hypotheses. Racial variations were examined using African Americans and Hispanics as moderators.

The results suggest that college education increases incorporated self-employment and reduces unincorporated self-employment. The impact of college education on incorporated self-employment is stronger for African Americans and Hispanics than for Whites. In contrast, its effect on unincorporated self-employment is stronger for Whites than for African Americans and Hispanics.

The findings provide empirical evidence of how college experience changes the motivation of starting an incorporated or unincorporated business. The results suggest that college education impacts African Americans and Hispanics differently than Whites in pursuing their career path of entrepreneurship.

It is the first study that examines the relationship between college education and incorporated/unincorporated self-employment. It also sheds light on radical variations.

This paper aims to examine the relationship between family responsibilities and family support, on the one hand, and decisions by men and women concerning owning a business, as well as how many hours they work in that business.

The authors used data collected by the US Current Population Survey between 1989 and 2011 and had a starting sample of 1,258,430 individuals, and a final sample of 27,147.

The authors found that both women and men are more inclined to own a business when they are married, have children or receive financial support from their spouse. They also found widespread gender differences in these analyses. The influence of family-related issues on owning a business is stronger for women than for men.

The findings indicate that male business owners work longer hours if they have young children. In contrast, female business owners reduce their work hours if they are married, have young children and receive support from their spouse. Implications are discussed.

Drawing on gender role ideology and structuralism perspectives, this study examines the impact of racial variation on the relationship between family characteristics and work–family decisions.

The study sample was drawn from the data collected by the U.S. Current Population Survey. This study used robust regression analysis to test their specific hypotheses that explore the role of racial variations on work–family decisions (measured in terms of weekly work hours).

The findings indicate that while overall men work longer hours when raising young children, both African American and Hispanic men tend to cut down on their work hours. Additionally, while marital status is associated with decreased work hours for White women, the reduction is smaller for Hispanic women. African American women actually end up increasing their work hours post marriage. Finally, while motherhood is associated with reduced work hours across racial groups, the decrease is more drastic for White women compared to their minority counterparts.

This study provides empirical evidence that work–family decision in the US African American and Hispanic households are not as strongly guided by the traditional gender role stereotypes, as is the case with White households. It also has important implications for the US employers who strive to leverage diversity and create inclusive organizations.

Given the increased population diversity in the USA, this study highlights the need to better understand the role of racial variations on the work–family decisions.

The purpose of this research is to examine how social capital derived through supply chain networks can help small businesses survive in times of a recession.

A theoretical framework with the respective propositions is developed, based upon an extensive literature review and a synthesis of evidence from the recent recession in the USA.

Small businesses need to invest in creating structural, relational and social capital prior to a recession in order to protect themselves from the additional uncertainty. Small businesses can develop social capital relatively easily and inexpensively through their supply chains.

This is the first study that directly investigates relationships among small businesses, social capital, supply chain, and recession. The findings should have a broad effect for countless communities throughout the USA as they depend on small businesses to be drivers of employment and state and local taxes.

This paper aims to help hosts or service providers of sharing economy-based accommodation (SEA) to attract new customers and retain existing customers by exploring the antecedents and outcomes of customers’ participation intention.

A questionnaire-based empirical study was conducted to explore the proposed relationships in SEA. Partial least squares modeling with SmartPLS was used to estimate the model and interpret the results.

The study shows that personal factors (utilitarian and hedonic motivation) positively influence customers’ participation intention. The relationship between environmental stimuli (perceived information fit-to-task and perceived visual appeal) and participation intention is negatively moderated by hedonic motivation. Furthermore, the results suggest a positive effect of participation intention on customer engagement behavior and the partial mediating role of experience evaluation.

This paper provides industry practitioners of SEA with valuable insights on attracting new customers and retaining regular customers. First, they can distinguish customers in terms of motivation and provide information based on their requirements. Second, they can encourage customers to evaluate their experience and provide feedback, which would help in promoting the accommodation and service and building a long-term and harmonious relationship with the customers.

This study first investigates the interaction effect of personal motivation and environmental stimuli on participation intention in SEA. It further examines the influence of participation intention on customer engagement behavior and the mediating role of experience evaluation.

Simultaneous hydrofracturing of multiple perforation clusters in vertical wells has been applied in the stimulation of hydrocarbon resources reservoirs. This technology is significantly impeded due to the challenges in its application to the multilayered reservoirs that comprise multiple interlayers. One of the challenges is the accurate understanding and characterization of propagation and deflection of the multiple hydraulic fractures between reservoirs and embedded interlayers.

Numerical models of the tight multilayered reservoirs containing multiple interlayers were established to study hydrofracturing of multiple perforation clusters and its influencing factors on unstable propagation and deflection of hydraulic fractures. Brittle and plastic multilayered reservoirs fully considering the influences of different in situ stress ratio and physical attributes for reservoir and interlayer strata on propagations of hydraulic fractures were investigated. The combined finite element–discrete element method and mesh refinement strategy were adopted to guarantee the accuracy of stress solutions and reliability of fracture path in computation.

Results show that the shear stress fields between adjacent multiple hydraulic fractures are superposed to cause fractures deflection. Stress shadows induce the shielding effects of hydraulic fractures and inhibit fractures growth to emerge unstable propagation behaviors, and a main single fracture and several minor fractures develop. As the in situ stress ratio increases, hydraulic fractures more easily deflect toward the direction of maximum in situ stress, and stress shadow and mutual interaction effects between them are intensified. Compared to brittle reservoir, plastic-enhanced reservoir may limit fracture growth and cannot form long fracture length; nevertheless, plastic properties of reservoir are prone to induce more microseismic events with larger magnitude.

The obtained fracturing behaviors and mechanisms based on engineering-scale multilayered reservoir may provide effective schemes for controlling and estimating the unstable propagation of multiple hydraulic fractures.

The purpose of this paper is to examine how the Chinese wine market can be meaningfully segmented and to explore marketing implications for the Australian wine sector.

The research is descriptive in nature, using an online survey to collect quantitative data on wine consumer behaviour. A total of 407 responses were obtained. Data analysis included descriptive analysis (frequency distributions) and cluster analysis.

The research identifies three clusters of wine consumers: “the extrinsic attribute-seeking customers”, “the intrinsic attribute-seeking customers” and “the alcohol level attribute-seeking customers”. These groups of consumers were categorised using a behavioural (benefit) segmentation base.

The use of an internet survey and convenience sample limits generalisation of the findings. The adoption of a behavioural basis in conducting the segmentation is a limitation. The use of more complex segmentation bases, such as psychographics, may yield a richer understanding of the Chinese wine consumer in future studies.

The customer profiles provide Australian wine marketers with an insight into Chinese wine consumer behaviour. Brand positioning can be improved by ensuring that the brand emphasises certain product attributes which the segments value when choosing wine.

Little previous research on market segmentation has been conducted in mainland China. For Australian wine marketers, this study provides a baseline study into market segmentation and may assist with targeting and brand positioning decisions.

Traditional laboratory measurements of soil water diffusivity (D) and soil water retention curve (SWRC) are always time-consuming and labor-intensive. Therefore, this paper aims to present a simple and robust test method for determining D and SWRC without reducing accuracy.

In this study, a D model of unsaturated soil was established based on Gardner–Russo model and then a combination of Gardner–Russo model with one-dimensional horizontal absorption method to obtain n and a parameters of Gardner–Russo model. One-dimensional horizontal absorption experiments on loam, silt loam and sandy clay loam were conducted to obtain the relationships between measured infiltration rate and cumulative infiltration with wetting front distance. Based on the obtained relationships, the measured infiltration data from the one-dimensional horizontal absorption tests were used to calculate n and a parameters and further constructing D and SWRC.

Both the calculated D and SWRC inversed from the infiltration data were in good agreement with the measured ones that obtained from the traditional horizontal absorption method and the centrifuge method, respectively. Error analysis indicated that only the infiltration data are enough to reliably synchronously determine D and SWRC.

A simple and robust method is proposed for synchronous determination of soil water diffusivity and water retention curve.

The purpose of this study is to investigate the effect of nano ZrC particles on the mechanical and electrochemical corrosion properties of FeCrAl alloys, providing a beneficial reference basis for the development of high-performance carbide reinforced FeCrAl alloys with good mechanical and corrosion properties in the future.

Nano ZrC reinforced FeCrAl alloys were prepared by mechanical alloying and spark plasma sintering. Phases composition, tensile fractography, corrosion morphology and chemical composition of nano ZrC reinforced FeCrAl alloys were analyzed by X-ray diffraction, scanning electron microscopy and energy dispersive X-ray spectroscopy, respectively. Microhardness and tensile properties of nano ZrC reinforced FeCrAl alloys were investigated by mechanical testing machine and Vickers hardness tester. Electrochemical corrosion properties of nano ZrC reinforced FeCrAl alloys were investigated by electrochemical workstation in 3.5 wt.% NaCl solution.

The results showed that addition of nano ZrC can effectively improve the mechanical and corrosion properties. However, excessive nano ZrC could decrease the mechanical properties and reduce the corrosion resistance. In all the FeCrAl alloys, FeCrAl–0.6 wt.% ZrC alloy exhibits the optimum mechanical properties with an ultimate tensile strength, elongation and hardness of 990.7 MPa, 24.1% and 335.8 HV1, respectively, and FeCrAl–0.2 wt.% ZrC alloy has a lower corrosion potential (−0.179 V) and corrosion current density (2.099 µA/cm2) and larger pitting potential (0.497 V) than other FeCrAl–ZrC alloys, showing a better corrosion resistance.

Adding proper nano ZrC particles can effectively improve the mechanical and corrosion properties, while the excessive nano ZrC is harmful to the mechanical and corrosion properties of FeCrAl alloys, which provides an instruction to develop high-performance FeCrAl cladding materials.
