Promoting entrepreneurship for sustainable development: Are education capital and ICT diffusion important?

AbstractThis article makes a valuable contribution to the existing literature on sustainable entrepreneurship by investigating the impact of entrepreneurship (both opportunity‐driven and necessity‐driven) on the achievement of sustainable development (SD) across its three dimensions. Additionally, it explores the underlying mechanisms through which this relationship is influenced. Specifically, the study examines the role of education capital (including education levels and government spending on education) and information and communication technology (ICT) diffusion (access, usage, and skills) in facilitating this relationship. The analysis focuses on data from Saudi Arabia and utilizes the Dynamic Ordinary Least Squares (DOLS) estimator. The findings indicate that only opportunity entrepreneurship exhibits a positive influence on SD. Furthermore, the study reveals that the positive impact of opportunity entrepreneurship is amplified through its interaction with government spending on education and tertiary education, leading to favorable indirect net effects on SD at both aggregated and disaggregated levels. Similarly, the interaction between opportunity entrepreneurship and ICT usage, as well as access, generates positive indirect net effects on SD across aggregated and disaggregated levels. Therefore, education capital and ICT diffusion are indeed key mechanisms that foster opportunity‐driven entrepreneurship for achieving SD. Education equips individuals with the necessary skills and mindset, whereas ICTs provide access to information, markets, and tools for business efficiency and innovation. By investing in education and promoting the widespread adoption and accessibility of ICTs, governments can empower individuals to become successful entrepreneurs while driving sustainable economic, environmental, and social progress.

Assessing the impact of environmental regulation on enterprise high-quality development in China: A two-tier stochastic frontier model

With the heightened concern of environmental sustainability, the relationship between environmental regulations and enterprise high-quality development(HQD) has become increasingly intertwined. However, the specific impact of environmental regulation on enterprise HQD remains unclear. Based on the panel data of A-share listed manufacturing companies in China from 2010 to 2020, this study constructs a two-tier stochastic frontier model to measure the bilateral effects of environmental regulation on enterprise HQD. The empirical results indicate the following: 1. The positive effect of environmental regulation makes the HQD of enterprises 54.995% higher than the frontier level, while its negative effect results in HQD being 16.215% lower than the frontier level. 2. The net effect of environmental regulation on enterprise HQD is positive over time, and it overall displays a W-shaped fluctuating downward trend. 3. Heterogeneity analysis, categorized by various criteria, shows that enterprises that are in non-heavily polluting industries, audited by listed accounting firms, state-owned enterprises, with higher investor attention, and in regions with lower intensity of environmental regulation, experience a greater net positive effect from environmental regulation. Policy implications are discussed to enhance the effectiveness of environmental regulation and high-quality development of enterprise

Habitat protection and removal of encroaching shrubs support the recovery of biodiversity and ecosystem functioning

AbstractLivestock overgrazing causes environmental degradation, species invasion, biodiversity loss, and productivity decline, with profound consequences for ecological sustainability and human livelihoods. Habitat protection can mitigate such impacts, but we know little about how the long‐term recovery of plant communities from livestock overgrazing depends on the presence of encroaching shrubs. Here, we explored how shrub encroachment mediates the effects of habitat protection (i.e., livestock exclusion and creation of UNESCO protected areas) on biodiversity recovery and ecosystem functioning (i.e., biomass productivity). We leveraged a long‐term (15–25 years) experiment of livestock exclusion and complemented it with the removal of an encroaching shrub species in pasture areas and protected areas. We reveal that habitat protection has positive effects on patterns of recovery. Yet, the effects of habitat protection are mediated by shrub encroachment. Encroaching shrubs have net positive effects on plant diversity in pasture areas but inhibit biodiversity recovery in protected areas. The combination of habitat protection and the removal of encroaching shrubs best enhances the recovery of plant diversity and biomass productivity. A potential underlying mechanism is the shift in plant interactions from facilitation for recruitment and associated resistance to competition for water. Understanding species interactions is key to guiding conservation and restoration actions which can turn degraded ecosystems back into functional, species‐rich communities.

Policy tug of war: EBacc, progress 8 and modern foreign languages in England

ABSTRACT Modern Foreign Languages (MFL) as a secondary school subject is affected by two policies, namely the English Baccalaureate (EBacc) and Progress 8, which contribute to the measurement of performance in exams at age 16 (GCSEs). In this paper, I discuss the concept of performance measurement in schools and the purpose it purportedly serves, before outlining these two policies and considering how they contribute to the culture of performance measurement and a non-neutral discourse around ‘standards’. I argue that the two policies act in tension in a game of tug of war with one another in such a way that the net positive effect on the subject of MFL is zero, but that the negative effect on students is substantial. I suggest that the policies act to impose middle-class notions of what it means to be educated on students, with a substantial negative effect on students from low socio-economic status backgrounds both in terms of their interest in the subject and their perceptions of their own value within the education system.

Cloud Characteristics during Intense Cold Air Outbreaks over the Barents Sea Based on Satellite Data

The Arctic experiences remarkable changes in environmental parameters that affect fluctuations in the surface energy budget, including radiation and sensible and latent heat fluxes. Cold air masses and cloud transformations during marine cold air outbreaks (MCAOs) substantially influence the radiative fluxes, thereby shaping the link between large-scale dynamics, sea ice conditions, and the surface energy budget. In this study, we investigate various cloud characteristics during intense MCAOs over the Barents Sea from 2000 to 2018 using satellite data. We identify 72 intense MCAO events that propagated southward using reanalysis data of the surface temperature and potential temperature at the 800 hPa level. We investigate the macro- and microphysical parameters and radiative properties of clouds within selected MCAOs, their dependence on sea ice concentration, and their initial air mass properties using satellite data. A significant increase in low-level clouds near the ice edge (up to +25% anomalies) and a smooth transition to upper-level clouds is revealed. The total cloud top height during intense MCAOs is generally 500–700 m lower than under neutral conditions. MCAOs induce a positive net cloud radiative effect, which peaks at +20 W m−2 (100 km from the ice edge) and gradually decreases towards the continent (−2.3 W m−2 per 100 km). Our study provides evidence for the importance of changes in the cloud radiative effect within MCAOs, which should be accurately simulated in regional and global climate models.

Urbanization, civil conflict, and the severity of food insecurity in Africa

AbstractThe objective of this article is to examine the impact of urbanization and civil conflicts on the severity of food insecurity for a panel of 43 African countries over the period 2000–2020. Subsequently, the heterogeneous choice models approach was used for the estimations. The results show that urbanization and civil conflict increase food insecurity. The parallel line probability hypothesis results specifically show that a one‐unit increase in urban growth rate increases the probability of belonging to a high‐risk food insecurity category by more than .6 times. Furthermore, the results show that the impacts of urbanization on food insecurity are modulated by civil conflicts in Africa leading to the net effect of .692. This corresponds to the policy threshold of 2.315 when the net positive effect is canceled out. Therefore, this study strongly recommends the need for African economies to develop urban agriculture while controlling the pace of urbanization in order to reduce food insecurity and avoid possible civil wars.Related ArticlesAsare‐Nuamah, Peter, Anthony Amoah, and Simplice A.

COVID-19 and Family and Peer Dynamics in Emerging Adults

Although research on the associations between COVID-19 and social relationships has garnered attention, there has been less of a focus on how COVID-19 was discussed within relationships themselves. The present study deepens the understanding of the wide reach of the pandemic by using quantitative surveys and open-ended responses to explore how individuals discussed and reacted to COVID-19 and related health guidelines in the context of their family and peer relationships. Data were collected from 132 young adults in the U.S. (age = 18.9 years, SD = 0.85; 50% female; 14% ethnically racially minoritized students) using standard procedures established by the university’s undergraduate research pool. Results suggest that young adults talked about COVID-19 more with their families than with their peers. They also reported sharing similar opinions about the pandemic with both their family and their peers. Young adults described COVID-19, overall, as having positive net effects within their family relationships but straining their peer relationships. Qualitative data provide additional, detailed insight on how the pandemic shifted interpersonal dynamics and family and peer relationships.

Dissimilarity in root traits and spatial distribution promotes the productivity of Piper nigrum L. and tree species in mixture systems

Background and aimsClarifying why species mixtures produce greater biomass compared to monocultures is important for understanding the effect of biodiversity in natural and agricultural systems. At present, it remains unclear whether differential root traits and spatial distribution between the liana and tree species can promote productivity of mixtures. MethodsA 4-month glasshouse experiment and a 3-year field trial were conducted to examine the influence of root traits and the vertical and horizontal root distribution on productivity of independently supported liana Piper nigrum (Pn) and five other species. In the glasshouse experiment, Pn was grown in monoculture or mixed with one of five species: Coffea arabica, Areca catechu, Artocarpus heterophyllus, Camellia oleifera, and Coffea canephora. In the field trial, the Pn/Ac system and each monoculture were tested. ResultsCompared with monoculture, all Pn and mixture systems showed a positive net effect and a high complementarity effect on shoot biomass. The variation in complementarity effect was mainly associated with dissimilarity in the multidimensional root space trait and a few specific individual traits (root phosphatase activity and mycorrhizal colonization) between Pn and the neighbors. In the field, Pn in the mixture increased proportion of root length in the 20–40 cm soil layer and allocated less root length in the space shared between Pn and Ac, thus achieving spatial separation of roots and promoting the final yield. ConclusionThese findings suggest that the dissimilarity in root traits and spatial distribution may be an important mechanism for promoting the productivity of mixtures of liana and tree species.

Green GDP accounting system from the perspective of resources and environment and a case study of Chongqing

Abstract Green GDP represents the net positive effect of national economic growth. The positive effect of national economic growth will be enhanced if there is a higher percentage of green GDP in GDP. From the perspective of resources and environment, this paper introduces SEEA-2012 accounting system with indirect calculating methods of green GDP in China, within which the value of natural resource depletion, environmental pollution damage and environmental quality degradation are included. In order to reasonably select valid indicators and data so as to get accurate accounting results, different valuation methods and operational formulas in economics are adopted to construct a new accounting system model, and the green GDP of Chongqing City in 2018-2020 is accounted for. Results show that the green GDP of Chongqing in recent three years is 1,838.889 billion Yuan, 1,964.724 billion Yuan and 2,111.2 billion Yuan, respectively, and proportions of green GDP in traditional GDP are 90.30%, 91.01% and 89.44% respectively. By studying and analyzing the dependence of Chongqing on natural resources and the ecological environment in the process of economic development, this paper provides theoretical support for the sustainable development of the urban economy and environment, provides a reference basis for the local government to formulate economic development planning, and also provides a reference for the construction of green GDP accounting system in similar ecological areas.

Climate policy uncertainty risk and sovereign bond volatility

This study investigates the relationship between climate policy uncertainty (CPU) risk and the volatility of sovereign bond return (SBV) in 43 economies from 2012 to 2021. It also innovatively examines how the volatility and asymmetry of CPU affect SBV. The study utilizes the GARCH-MIDAS model to handle mixed-frequency data and applies the DCC-GARCH and TVP-VAR-DY models to investigate dynamic correlations and spillover effects. The empirical results show that CPU negatively impacts SBV, while CPU's volatility or positive shocks tend to elevate SBV, especially in more climate-resilient developed economies. In addition, critical international events can influence dynamic correlations and spillover effects between CPU (or its volatility) and SBV, particularly when climate policy is highly valued. From a risk transmission standpoint within the sovereign bond system, CPU and its volatility exert positive net spillover effects on SBV in the majority of economies. This study offers valuable insights for investors and policymakers, aligning with the goals of sustainable development for effective management of CPU risks.

Contribution of Agricultural Productivity to Industrialization in Africa

Purpose: The objective of this study is to investigate the direct and indirect effects of agricultural productivity on industrialization. It also looks for the mediating role of infrastructural development on the effects of agricultural productivity on industrialization. Method: The system Generalized Method of Moments (GMM) methodology for 45 African countries is applied. It covers the period from 2005 to 2022. Results: The results show that agricultural productivity has a positive significant role on industrialization in Africa. This result is robust when industrialization is measured by employment in industry (EMIND). Infrastructural development has an enhancing role on the agricultural productivity-industrialization nexus. These results are robust for the two different measures of industrialization but are more enhancing on Employment in Industry than on Manufacturing Value Added (MVA). The study also observes that agricultural productivity interacts with the Water and Sanitation Index (WSS) on MVA to yield a positive net effect. Moreover, agricultural productivity interacts with ICT (Information and Communication Technology) and ECI (Electricity composite index) on both MVA and EMIND to yield positive synergy effects. Implications: The Electricity Composite Index is still not sufficient in Africa. Equally, there is a need for some countries like Chad, Ethiopia, Mozambique, and Niger to boost WSS above this threshold of 32.96 since this threshold is below the mean value for Africa as a whole. Policy-wise, it could be recommended that both agricultural productivity and infrastructural development should be strengthened, with emphasis on electricity, so as to achieve the much-needed level of industrialization for Africa.

Systematic distributions of interaction strengths across tree interaction networks yield positive diversity-productivity relationships.

Understanding the mechanisms underlying diversity-productivity relationships (DPRs) is crucial to mitigating the effects of forest biodiversity loss. Tree-tree interactions in diverse communities are fundamental in driving growth rates, potentially shaping the emergent DPRs, yet remain poorly explored. Here, using data from a large-scale forest biodiversity experiment in subtropical China, we demonstrated that changes in individual tree productivity were driven by species-specific pairwise interactions, with higher positive net pairwise interaction effects on trees in more diverse neighbourhoods. By perturbing the interactions strength from empirical data in simulations, we revealed that the positive differences between inter- and intra-specific interactions were the critical determinant for the emergence of positive DPRs. Surprisingly, the condition for positive DPRs corresponded to the condition for coexistence. Our results thus provide a novel insight into how pairwise tree interactions regulate DPRs, with implications for identifying the tree mixtures with maximized productivity to guide forest restoration and reforestation efforts.

Positive and negative plant−plant interactions influence seedling establishment at both high and low elevations

Deciphering how plants interact with each other across environmental gradients is important to understand plant community assembly, as well as potential future plant responses to environmental change. Plant−plant interactions are expected to shift from predominantly negative (i.e. competition) to predominantly positive (i.e. facilitation) along gradients of environmental severity. However, most experiments examine the net effects of interactions by growing plants in either the presence or absence of neighbours, thereby neglecting the interplay of both negative and positive effects acting simultaneously within communities. To partially unravel these effects, we tested how the seedling establishment of 10 mountain grassland plants varied in the presence versus absence of plant communities at two sites along an elevation gradient. We created a third experimental treatment (using plastic plant mats to mimic surrounding vegetation) that retained the main hypothesised benefits of plant neighbours (microsite amelioration), while reducing a key negative effect (competition for soil resources). In contrast to our expectations, we found evidence for net positive effects of vegetation at the low elevation site, and net negative effects at the high elevation site. Interestingly, the negative effects of plant neighbours at high elevation were driven by high establishment rates of low elevation grasses in bare soil plots. At both sites, establishment rates were highest in artificial vegetation (after excluding two low elevation grasses at the high elevation site), indicating that positive effects of above-ground vegetation are partially offset by their negative effects. Our results demonstrate that both competition and facilitation act jointly to affect community structure across environmental gradients, while emphasising that competition can be strong also at higher elevations in temperate mountain regions. Consequently, plant−plant interactions are likely to influence the establishment of new, and persistence of resident, species in mountain plant communities as environments change.

Optimization and production of highly stable amylase isolated from Citrobacter portucalensis using low-cost agro-industrial wastes as substrates: Prospective therapeutics

Starch hydrolyzing amylases are among the vital enzymes used in the food, textile, detergent, and pharmaceutical industries. The aim was to isolate amylase bacteria from agricultural soil, its extraction and subsequent purification. Within the scope of this work, using a 1% starch agar medium, potent thermostable bacterial amylase (A-4) was isolated from agricultural soil samples. Molecular analysis revealed the amylase-producing bacterial strain (A-4) to be Citrobacter portucalensis. We used agro-industrial-based wastes (wheat bran, potato peel, and sugarcane bagasse) in amylase production. Culture condition optimization showed that high amylase activity of 4.96 U/mL was obtained at temperature 55 °C and pH 5.0 after 72 h of incubation. The best-suited substrate was nitrogen, and carbon sources were wheat bran, yeast, and lactose for enzyme production. In addition, metal ions Ca+2 and Mg+2 showed a net positive effect on the rate of the enzymatic reaction, and Al+3 and Co+2 inhibited the activity. Protein purification results demonstrated a 4-fold increase with 13% yield and specific activity of 40 U/mL/min. SDS-PAGE indicated the molecular weight of partially purified protein as ∼56 kDa. The stain removal efficiency of the purified enzyme showed considerable results. The finding revealed the use of low-cost and readily available substrates, making C. portucalensis (A-4) a promising candidate for detergent and pharmaceutical industries.

Which institutional investors can improve the level of corporate ESG information disclosure?

The inconsistency of existing findings on the relationship between institutional investors' shareholdings and the level of corporate Environmental, Social and Governance (ESG) disclosure may lie in the insufficient consideration of the heterogeneity of institutional investors and investee firms. In this paper, from the perspective of institutional investor heterogeneity, we use a two-way fixed effects model to examine the impact of institutional investors on corporate ESG disclosure and the possible mechanism of this impact using a sample of Chinese A-share-listed firms from 2012 to 2020. We show that institutional investor shareholding can improve the level of corporate ESG information disclosure by enhancing auditor supervision and analyst attention to these external supervision. In terms of institutional investor heterogeneity, it is found that independent institutional investors and stable institutional investors play a stronger role in promoting the level of ESG information disclosure. Moreover, the positive net effect of the institutional investors on improving the level of ESG information disclosure is more pronounced in non-heavily polluting industries and state-owned enterprises. This paper enriches the impact of institutional investors' shareholding on corporate ESG disclosure from a heterogeneity perspective.

Digitalization and employment in Europe: the role of firm's size and the complementarity of R&D

The empirical research finds a contingent, slightly positive net effect on the relationship between digitalization and employment, resulting from the automation and reinstatement of jobs, the two countervailing forces revealed by the theoretical literature. We dig down at the features of this relationship, using two waves of Innobarometer surveys to capture the innovation investments of a sample of European enterprises in 2015 and 2016. Adding to previous studies, we identify an inverted U‐shape between degrees of digitalization and employment; this effect is more prominent in small companies with fewer than 50 employees. The effect diminishes for very large companies. In addition, we show complementarity links between research and development (R&D) investments and digital ones proxied by investing in software development and acquiring hardware and software. Specifically, we find support for a positive association between employment and investment in information technology (IT) assets and R&D. On average, companies that invest in both IT and R&D have 11.5% more employees than those that embrace just one. While we observe that small companies that invest in either type of IT asset employ more people, at larger enterprises, the positive effect is only found when they invest in both. The study supports the findings using alternative regression methods, quantile, and Lewbel instrumental variables.

Effect of ethylene pretreatment on tomato plant responses to salt, drought, and waterlogging stress.

Salinity, drought, and waterlogging are common environmental stresses that negatively impact plant growth, development, and productivity. One of the responses to abiotic stresses is the production of the phytohormone ethylene, which induces different coping mechanisms that help plants resist or tolerate stress. In this study, we investigated if an ethylene pretreatment can aid plants in activating stress-coping responses prior to the onset of salt, drought, and waterlogging stress. Therefore, we measured real-time transpiration and CO2 assimilation rates and the impact on biomass during and after 3days of abiotic stress. Our results showed that an ethylene pretreatment of 1ppm for 4h did not significantly influence the negative effects of waterlogging stress, while plants were more sensitive to salt stress as reflected by enhanced water losses due to a higher transpiration rate. However, when exposed to drought stress, an ethylene pretreatment resulted in reduced transpiration rates, reducing water loss during drought stress. Overall, our findings indicate that pretreating tomato plants with ethylene can potentially regulate their responses during the forthcoming stress period, but optimization of the ethylene pre-treatment duration, timing, and dose is needed. Furthermore, it remains tested if the effect is related to the stress duration and severity and whether an ethylene pretreatment has a net positive or negative effect on plant vigor during stress recovery. Further investigations are needed to elucidate the mode of action of how ethylene priming impacts subsequent stress responses.

Tree diversity increases productivity through enhancing structural complexity across mycorrhizal types.

Tree species diversity and mycorrhizal associations play a central role for forest productivity, but factors driving positive biodiversity-productivity relationships remain poorly understood. In a biodiversity experiment manipulating tree diversity and mycorrhizal associations, we examined the roles of above- and belowground processes in modulating wood productivity in young temperate tree communities and potential underlying mechanisms. We found that tree species richness, but not mycorrhizal associations, increased forest productivity by enhancing aboveground structural complexity within communities. Structurally complex communities were almost twice as productive as structurally simple stands, particularly when light interception was high. We further demonstrate that overyielding was largely explained by positive net biodiversity effects on structural complexity with functional variation in shade tolerance and taxonomic diversity being key drivers of structural complexity in mixtures. Consideration of stand structural complexity appears to be a crucial element in predicting carbon sequestration in the early successional stages of mixed-species forests.

Environmental, social, and governance perfomance and default risk in the eurozone

This paper analyses the impact of sustainability through ESG factors on the default risk. The sample consists of 990 non-financial firms in the Eurozone over the period 2004–2020. The results show that ESG factors influence default risk, although this relationship could be influenced by the economic cycle. Also, the results highlight a significant interaction effect between firm size and ESG which affects default risk. Considering firm size by terciles, the evidence obtained shows that smaller and medium-sized firms have a positive net effect of a high ESG score on their default risk, while the opposite effect was found among larger firms.

Business intelligence adoption among small apparel retailers in KwaZulu-Natal

Business intelligence (BI) can assist businesses with the analysis of information to make better decisions to improve business performance; however, a lack of research with respect to the adoption of BI tools specifically in the SMME apparel sector has been observed. Developments in information technology (IT) have led to an increase in competitiveness among providers, resulting in a plethora of offerings for customers to choose from. As such, businesses are operating in evolving and complex environments where business intelligence systems (BIS) have become essential. The aim of this study was to establish the factors that influence the adoption of BI by micro-small apparel retailers in KwaZulu-Natal. The study was a cross-sectional survey that sampled 132 apparel business owners who were selected using purposive sampling. A survey questionnaire was used to collect the data. The data was analyzed using the Statistical Package for Social Sciences (SPSS) Version 13.0. This study found that the main inhibitors to the adoption of BI systems among small apparel retailers are cost-related. However, an interesting finding was that although cost had a negative relationship to adoption in the results, most of the respondents still indicated that they were able to make financial plans to adopt BI. The study recommends that small apparel business owners prioritize the adoption of BI as a tool for business operations. The adoption of such tools would have a net positive effect on the operations of such businesses.
