Private Investment and Economic Development: Ensuring Sustainability in the Future

Objectives: The objectives of this study are 1) to examine the role of private investment in economic development towards sustainability in Vietnam by utilizing provincial-level data from the period 2000–2020 and 2) to construct an economic development index based on four main pillars: economy, science and technology, energy models, and multidimensional poverty. Methods/Analysis: The study employed the CS-ARDL estimation method to investigate the short- and long-term relationships between private investment and economic development. Furthermore, to address issues related to slope heterogeneity, endogeneity, and cross-sectional dependence, the study applied the AMG and CCEMG models to assess this relationship in the long term. Findings: The study identified a positive long-term relationship between private investment and economic development. Additionally, investment in science and technology, agricultural land urbanization, vocational training for labor, trade openness, and private sector finance exhibited significant associations with private investment. Novelty/Improvement: The study successfully developed an economic development index and elucidated the relationship between private investment and economic development. The research underscores two critical strategies for attracting and promoting private sector investment: improving the workforce through training and expanding export markets. The effective implementation of these strategies can address subsequent challenges and expedite sustainable economic development progress. Doi: 10.28991/HEF-2023-04-04-04 Full Text: PDF

PSI-21 The Role of N-Carbamylglutamate Supplementation During Last Third of Gestation in Nutrient Restricted Twin-Bearing Ewes

Abstract Nutrient restriction in sheep during pregnancy normally occurs in Patagonia with negative effects on ewe body condition (BCS) and reproductive performance. N-carbamylglutamate (NCG), an analogue of N-acetylglutamate, is postulated to improve urea recycling, nitrogen utilization and antioxidant capacity in ruminants. The objective of this study was to evaluate the effect of oral NCG supplementation in naturally nutrient restricted grazing twin-bearing ewes, on maternal body weight (BW) and body condition score (BCS), serum biochemical indexes and antioxidant capacity in mid-late gestation. Ten twin-bearing ewes were orally dosed once-daily with 60 mg/kg BW NCG in a water carrier from 100 to 140 days of gestation (dg) and were compared with unsupplemented controls (CON; n = 8). Maternal BW, and BCS were recorded every 10 days, from 100 to 140 dg. Blood samples were collected at the same time points to evaluate plasma metabolites (NEFA, urea, total protein, albumin, globulin, Ca, P, Mg, Cholesterol, ASAT, CK, GGT, GLDH, total bilirubin and triglycerides), antioxidant status [malondialdehyde (MDA)], and total antioxidant capacity (TAC). Ewes were managed as a single mob in a paddock with natural pasture (3.3% CP, 1.9 Mcal/kg ME), supplemented with alfalfa hay (600 g· ewe-1· /day-1; 13% CP and ME 2.2 Mcal/kg ME) from 130 dg, with a stocking rate of 0.9 ewes per hectare and a dry matter availability of 525 kg per hectare, representative of Patagonian prairie conditions. The effect of treatment on ewe BW, BCS and plasma metabolites were analyzed using REML analysis in R using lme4 R package with time (dg) and treatment (and their interaction) as fixed effects and animal as the random effect. Ewe BW increased (P < 0.0001) and BCS decreased (P = 0.005) with advancing gestation, but there was no effect of treatment. There was a tendency for a treatment effect (P = 0.07) on plasma urea with ~10% less concentrations in NCG than CON ewes at 130 dg (P = 0.08) and 140 dg (P = 0.04). There was a treatment by time interaction for total bilirubin (P = 0.005), phosphorus (P = 0.02), and a similar trend for albumin (P = 0.09). Ewes supplemented with NCG had~10% lower concentrations of bilirubin at 100 (P = 0.01) and 120 dg (P = 0.04), less concentrations of phosphorus (P = 0.003) and albumin (P = 0.02) at 140 dg compared with CON ewes. No other effects of treatment on blood metabolites or antioxidant status or capacity were observed. Collectively these results suggest that supplementation of nutritionally restricted ewes with 60 mg/kg BW from 100 to 140 dg did not influence BW or LWT but may have some effects on liver function, protein metabolism, urea recycling, feed intake and/or feed efficiency which warrant further investigation.*Funded by FONDECYT Project N°1221042; AgResearch Strategic Science Investment Fund.

Enhancing Impact: A Call to Action for Equitable Implementation Science

Despite investments in evidence-based interventions and Implementation Science, most evidence-based interventions are not widely or routinely adopted, delivered, or sustained in many real-world community and healthcare settings. This gap is even greater in settings and populations experiencing numerous social and structural barriers to health, with important implications for persistent patterns in health inequities. In this Viewpoint, as part of a Special Issue on Advancing the Adaptability of Chronic Disease Prevention and Management through Implementation Science, we outline seven calls to action for the field of Implementation Science, with the goal of encouraging researchers, practitioners, and funders to be more intentional and accountable in applying Implementation Science to have greater impact on promoting health equity. Calls to action include (1) enhance public health, community, and multi-sectoral partnerships to promote health equity and equitable implementation; (2) revisit and build the evidence base needed to promote health equity and impact at multiple levels; (3) prioritize focus on policy development, dissemination, and implementation; (4) be agile and responsive in application of Implementation Science frameworks, processes, and methods; (5) identify and redefine meaningful metrics for equity and impact; (6) disseminate scientific evidence and research to a diverse range of partners and potential beneficiaries; and (7) extend focus on de-implementation, mis-implementation, and sustainability which are central to enhancing health equity. Additionally, we outline why a focus on prevention and public health is essential to making progress towards health equity in Implementation Science, summarize important advancements that the field has made towards making equity more foundational, and pose important research questions to enhance equitable impact of work in this area.

Spatiotemporal evolution and determinants of urban land use efficiency under green development orientation: Insights from 284 cities and eight economic zones in China, 2005–2019

Green development is essential for improving urban land use efficiency (ULUE) as it seeks to optimize resource utilization and minimize waste and pollution. However, a long-term evolution of ULUE and its determinants under the context of green development are less discussed in existing studies. Drawing on remote sensing and statistical data and utilizing the super efficiency slack-based model (SBM) and the geographically and temporally weighted regression (GTWR) model, this study evaluates green development-oriented ULUE and its spatiotemporal associations with determinants across 284 cities and eight economic zones in China from 2005 to 2019. We found that the green development-oriented ULUE in China generally increased in 15 years (from 0.404 to 0.55), with higher levels in coastal and northwestern regions than in central regions. Besides, per capita GDP, investment in technology and science, and degree of openness generally contributed to ULUE (over 75% observations showed positive coefficients), while investment in real estate had a negative impact on ULUE. The impact of industrial structure on ULUE experienced a transition from positive to negative in northern and eastern cities, with the highest coefficient decreasing from 0.194 in 2005 to −0.032 in 2019. Population density contributed to ULUE in southern and northwestern cities during 2005–2010 (coefficients ranging from 0.008 to 0.198), while it negatively influenced ULUE in most cities since 2015 (coefficients ranging from −0.009 to −0.283). The correlation between nighttime light, per capita road, and ULUE showed noticeable south-north differentiation. Our study provides valuable guidelines for Tailor-made strategies of efficient urban management towards sustainable urbanization.

Building Agro-Industrial Capabilities in the Sugarcane Supply Chain in Brazil

Background: This study aims to explore how domestic entrepreneurs can benefit from the thriving global agribusiness by establishing themselves in agro-industrial segments that can best remunerate capital and labour. The ways in which domestic entrepreneurs in Brazil enter different segments of the agribusiness industry were assessed with specific attention to implications for the development of local agro-industrial capabilities. Methods: We assessed the current market share of domestic companies in relation to foreign multinationals in various segments of the sugar and ethanol supply chain in Brazil. Results: Foreign multinationals are market leaders in the fertilizers, machinery and trading segments (domestic companies market share is 20.3%, 33.3% and 42.9% in those segments respectively). However, Brazilian companies have achieved higher market share in segments such as plant breeding, sugarcane processing and farming (domestic market share is 93.2%, 67.4% and 75.5% respectively). Plant breeding, farming and trading benefit from governmental support in research, subsidized credits and market policies respectively. Conclusions: By investing in agro-industrial sectors developing countries can benefit from agribusiness expansion for their economic growth. Investments in science and technology and domestic regulatory actions can help to build country capabilities, although the impacts are sometimes limited to the agro-industrial sectors where domestic companies are more competitive. These lessons can help other developing countries to assess their opportunities and challenges for agro-industrial development.

The Mechanism and Countermeasures of the Impact of State Subsidy Backslide on the Efficiency of Waste-to-Energy Enterprises—A Case Study in China

The scientific investment decision model of waste incineration power generation is helpful in providing a scientific basis for the government and environmental protection enterprises to formulate reasonable waste prices. The waste incineration power generation project revenue and cost composition framework, based on the project net present value of factors affecting causality analysis, the construction of a waste incineration power generation PPP project net present value system dynamics model, and the use of Vensim PLE software, version 7.3.5, combined with the garbage power generation of listed companies, was built, and we put into use the enterprise’s financial data and the author’s research of the case of the BOT (Build–Operate–Transfer) project data to examine the validity of the model test, simulation, and sensitivity analysis. The results show that the regression of a national subsidy does not necessarily lead to a price adjustment of the waste disposal fee, and when a change in tariff subsidy occurs, the loss brought by the reduction in a feed-in tariff can be compensated by increasing the income from carbon sinks, decreasing the intensity of investment through technological advancement, improving the coefficient of waste power generation through garbage classification, and increasing the utilization of production capacity through the treatment of multiple wastes in a single or a combination of ways.

Beyond Bias Minimization: Improving Intelligence with Optimization and Human Augmentation

For the last half-century, the U.S. and Allied Intelligence Community (IC) has sought to minimize the ostensibly detrimental effects of cognitive biases on intelligence practice. The dominant approach has been to develop structured analytic techniques (SATs), teach them to analysts in brief training sessions, provide the means to use SATs on the job, and hope they work. The SAT approach, however, suffers from severe conceptual problems and a paucity of support from scientific research. For example, a highly promoted SAT—the analysis of competing hypotheses—was shown in several recent studies to either not improve judgment quality or to make it worse. This article recaps the key problems with the SAT approach and sketches some alternative interventions. At the core of these proposals is the idea that intelligence agencies should be focused broadly on improving intelligence and not narrowly on minimizing bias. While the latter contributes to achieving the former, overemphasis on bias minimization could inadvertently bias agencies toward a singular form of intervention, blinding then from potentially more effective interventions. Two lines of alternative intervention are sketched. The first line focuses on postanalytic statistical optimization methods such as recalibration and performance-weighted aggregation of analysts’ judgments. The second line focuses on a broad human augmentation program to optimize human cognition through better sleep, exercise, nutrition (including nootropic compounds), and biometric tracking. Both lines of effort would require substantial scientific investment by the IC to examine risks and efficacy.

The driving mechanism and path selection of green development in Chinese cities

Green is the background color of high-quality development of Chinese cities. By constructing a theoretical model of the driving force and driving mechanism of China’s urban green development, this paper simulates the green development path of Chinese cities based on the panel data of Chinese cities from 2010 to 2020. The empirical results show that, firstly, the driven force formed by scientific and technological in novation, the action force formed by structural adjustment and the driven force formed by environmental regulation can drive Chinese cities to achieve green development. Secondly, the pressure of different paths on the ecological environment showed a gradual downward trend, the ecological environment pressure under the baseline scenario was the highest, and the ecological environment pressure driven by single factors may be lower than that driven by two factors. Finally, the comprehensive driven path formed by the combination of innovation driven, structure driven and environment a driven is a better path for China’s urban green development. Therefore, the green development of Chinese cities requires policy intervention, different cities need to formulate green development plans according to local conditions, and should consider the combination of policies. In the future, Chinese cities need to increase investment in science and technology, guide all entities to develop in the direction of resource conservation and pollution reduction, adjust the industrial structure, promote their development in the direction of cleanliness, increase environmental protection investment, standardize the development of all entities in the direction of environmental protection, and give full play to the synergy of the three major policies to achieve green development.

Spatial–Temporal Characteristics and Influencing Factors of Marine Fishery Eco-Efficiency in China: Evidence from Coastal Regions

Marine fishery is an important part of China’s maritime power strategy. Improving the ecological efficiency of marine fishery is the inevitable way to achieve the sustainable development of fishery. Based on the perspective of industrial sustainable development, this study used the Super-SBM model to evaluate the ecological efficiency of marine fishery in 11 coastal provinces of China from 2011 to 2020. Combined with Malmquist index, Moran index and other methods, the spatial and temporal evolution characteristics were analyzed. On this basis, the Tobit panel model was used to explore the influencing factors of marine fishery eco-efficiency. The results show that: (1) From 2011 to 2020, the marine fishery eco-efficiency in the 10 coastal provinces and cities of China shows a clear trend of improvement, and the efficiency values in high-efficiency areas remain basically stable. The relative gap between efficient and inefficient regions remains significant. (2) From the perspective of spatial distribution characteristics, the ecological efficiency of marine fishery in coastal provinces and cities in China had no obvious spatial correlation, and showed a trend of cross-distribution between high-efficiency regions and low-efficiency regions. (3) The change of marine fishery eco-efficiency is the result of a variety of influencing factors. Fishery industrial structure, scientific and technological support levels and environmental regulation play a role in promoting the improvement of marine fishery eco-efficiency. Therefore, optimizing the structure of the fishery industry, improving environmental regulation and increasing investment in science and technology are all effective measures for local governments to improve the eco-efficiency of marine fisheries.

The Potential of Brazilian Beef Production from the Perspective of Effectiveness and Efficiency

The general objective of the research is to analyze the national bovine protein market in order to compare the Brazilian production and productivity in relation to the main world producers of bovine livestock, in order to discuss, under the prism of effectiveness and efficiency in the perspective of rural administration. For the analysis procedure of this work, the SWOT Matrix tool was applied, focusing on the criteria of "strength", "weakness", "threat" and "opportunity". Based on the results found in the research, it was possible to conclude that Brazil has significant chances of growth for this sector of the economy, but it will only be able to sustain itself in this market when efficiency is also part of the decision-making process. Based on the SWOT Matrix, it was observed that the “strength” of the country in this segment is concentrated, in general, in the significant available agricultural production areas and in the hegemonic technologies existing at the national level. In the field of “weakness”, it was observed that the concentration of technologies in a certain group of rural producers reduces the diversification of production technologies, which may represent a loss of competitiveness in certain market niches, mainly in those more demanding sectors. In addition, high production costs were also perceived as a “weakness” that impacts the country's competitive power. The “opportunities”, on the other hand, are more linked to the growing global demand for food, placing Brazil at the forefront of food on the planet. The “threats”, in turn, observed in this study are linked to food safety and more demanding production criteria in competitive markets, which impose, in the Brazilian reality, the need to adopt a strategic vision and greater investments in science and technology, aiming to improve the development, in the national territory, of technologies more adapted to the realities of different biomes, such as the Amazonian biome.

Can urban land market reform mitigate industrial emissions? Environmental evidence from 257 prefecture-level cities in China

In the period of planned economy, China used low-cost land investment to drive economic development for a long time, which brought problems such as low efficient use of natural resources and environmental pollution. Under the dual pressure of economic development and environmental protection, Chinese government has begun to implement the urban land market reform, hoping to gradually change the extensive economic development model with high input and low output through the market mechanism. In order to investigate whether the urban land market reform can reduce industrial emissions and promote the transformation of socioeconomic, this paper constructs industrial land transactions and socioeconomic panel data of 257 prefecture-level cities in China from 2007 to 2020. The research results show that (1) The urban land market reform has reduced industrial emissions through changing the behavior of local governments in fiscal decentralization and the behavior of industrial enterprises. (2) The regional competition and cooperation brought by urban land market reform have regional heterogeneity in the emission reduction effect of industrial emissions. (3) The emission reduction effect of urban land market reform has a spatial spillover effect, which not only affects the local area, but also affects neighboring cities. We suggest that Chinese government needs to continue to carry out ULMR and increase scientific investment and technological innovation, promote the transformation of the industrial economy, and promote healthy competition among local governments. The findings not only provide valuable insights for the future reform of China's market economy, but also provide practical reference for social changes for other countries in the transition period of the world.

Degradation Science from Nanometers to Kilometers: A Pathway to Rapid Detection for Reliable Photovoltaics

Photovoltaics reliability for terrestrial applications has more than four decades of history and experience. International standards development has prevented many early life failures and must be continued in the future. Yet, as the module product development cycle is measured in mere months, additional investment in the fundamental degradation science and rapid detection should be developed. In this article, a brief strategy is provided addressing indoor accelerated, outdoor testing, and modeling efforts required to retain high reliability in the following decade.

State of the art on the knowledge

Considering the diversity of non-flying small mammals in the Neotropical region, the impact of landscape change and the lack of knowledge about the real impacts on this megagroup, we developed a scientometric analysis over a 50-year interval. The study focuses on neotropical countries, especially Brazil, and aims to point out how these communities are structured in different environments. We searched for word combinations in the databases of the Science, Scielo and Scopus websites, resulting in 5,144 records, of which 2,941 were removed from the analysis due to their inadequacy to our topic. Of the 2,203 manuscripts that fit the objective of our study, 816 articles were carried out in Brazil, representing 46% of all publications related to the Neotropical region. The biome with the highest number of publications was the Atlantic Forest. While the knowledge gaps about the Cerrado and Amazon biomes are still evident. It is known that, in Brazil, the inequality in the concentration of investments in research is also reflected in quality scientific production. In this sense, our results highlight the need for a serious policy of investments in science and technology in the country, with partnerships between states and evaluation of the least studied biomes.

The Owl and the Occult: Popular Politics and Social Liminality in Early Modern South Asia

AbstractHistorians of Islamic occult science and post-Mongol Persianate kingship in the Ottoman, Safavid, and Mughal Empires have in recent years made clear just how central this body of knowledge was to the exercise of imperial power. Alongside, scholarship on tantra has pointed to its diffuse persistence in the early modern period. But what dynamics beyond courts and elite initiates did these investments in occult science and tantra unleash? Through a focus on the seventeenth-century Mughal court and the Rajput polity of Marwar in the eighteenth century, this article weaves together the history of animals with that of harmful magic by non-courtly actors. It demonstrates the blended histories of tantra, Islamicate occult sciences, and folk magic to argue that attributions of liminality encoded people, animals, and things with occult potential. For some, like the owl, this liminality could invite violence and death and for others, like expert male practitioners, it could generate authority. By the eighteenth century, the deployment of practical magic towards harmful or disruptive ends was a political tool wielded not only by kings and elite adepts for state or lineage formation but also by non-courtly subjects and “low”-caste specialists in local social life. States and sovereigns responded to the popular use of harmful magic harshly, aiming to cut off non-courtly access to this resource. If the early modern age was one of new ideologies of universal empire, the deployment of occult power outside the court was inconsistent with the ambitions of the kings of this time.

Does the low-carbon city pilot contribute to the blue sky defense? Evidence from China.

China's goal of ecological civilization construction simultaneously faces the dual strategic tasks of pollution control and carbon reduction (PCCR). In addition to carbon reduction, does the low-carbon city pilot (LCCP) further contribute to the blue sky defense? This study investigates the impact of the LCCP on air pollution by employing a multiperiod difference-in-differences (DID) model based on data from 276 Chinese cities. The results show the following: (1) Compared with nonpilot areas, the LCCP reduces PM2.5 levels in pilot areas by approximately 1.50% on average, which is achieved by "industrial restructuring", "government investment in science and technology (S&T)", and "green lifestyle". (2) The LCCP has heterogeneous effects on air quality across cities with different resource endowments and industrial attributes, showing a greater air quality improvement in nonresource-based cities (NREB cities) and old industrial base cities (OIB cities) than in other city types. (3) The positive impact of the LCCP on air improvement in the pilot areas is derived from "pollution control effects" rather than "pollution transfer effects". This study provides useful policy implications for the comprehensive green transition and exploration of synergistic governance for PCCR in China.

FDI Quality, Green Technology Innovation and Urban Carbon Emissions: Empirical Evidence from China

High-quality introduction and utilization of foreign investment is a new engine for China’s further opening up and plays a significant role in urban carbon emission reduction in the context of carbon peaking and carbon neutrality strategies. By constructing a comprehensive assessment index of Foreign Direct Investment (FDI) quality and using panel data from 283 Chinese cities from 2006 to 2019, this paper systematically examines the impact of FDI quality on urban carbon emissions and identifies the mechanism of green technology innovation in order to clarify the correlation among the three. The results show that FDI quality upgrading can significantly reduce urban carbon emissions, which is mainly manifested by FDI management and FDI export capacity to suppress total carbon emissions. The above effect of FDI quality is more significant in cities with a low rationalization degree of industrial structure, high investment in science and technology, strong environmental regulation and high dependence on foreign capital. Green technology innovation is an intermediary mechanism for FDI quality to have a carbon emission reduction effect. Looking at different areas, foreign companies in the eastern regions can promote carbon emission reduction through independent innovation, while the central and western regions essentially rely on imitative innovation; however, there is a delay in the role of innovation quality. Further study suggests that the carbon emission reduction effect of FDI quality has an obvious characteristic of threshold, which will be slightly weakened with the increase in the quantity of imitative innovation but strengthened with the improvement of the quantity of independent innovation and the quality of innovation. The conclusion aims to provide policy implications for China to explore a sustainable pathway that combines promoted opening with carbon reduction targets.

Effects of the digital economy on carbon emissions in China: an analysis based on different innovation paths.

As the digital economy grows rapidly around the world, how would it impact carbon emissions? This paper discusses this issue from the perspective of heterogeneous innovation. Based on the panel data of 284 cities in China from 2011 to 2020, this paper empirically examines the impact of the digital economy on carbon emissions as well as the mediating and threshold effects of different innovation modes. The study finds that the digital economy can significantly reduce carbon emissions; this conclusion holds after a series of robustness tests. Independent innovation and imitative innovation are important channels through which the digital economy affects carbon emissions, but technological introduction is not an effective way. For regions with high levels of financial investment in science and innovative talents, the reduction in carbon emissions from the digital economy is more significant. Further research shows that the effect of the digital economy on carbon emissions has a threshold feature, with an inverted U-shaped relationship between the two, and that an increase in autonomous innovation and imitation innovation can enhance the digital economy's carbon reduction effect. Therefore, it is necessary to strengthen the capacity of independent innovation and imitation innovation to exploit the carbon-cutting effect of the digital economy.
