From Waste to Innovation: A Circular Economy Approach for Tissue Engineering by Transforming Human Bone Waste into Novel Collagen Membranes

The aim of the circular economy is to treat waste as a valuable raw material, reintegrating it into the industrial economy and extending the lifecycle of subsequent products. Efforts to reduce the production of hard-to-recycle waste are becoming increasingly important to manufacturers, not only of consumer goods but also of specialized items that are difficult to manufacture, such as medical supplies, which have now become a priority for the European Union. The purpose of the study is to manufacture a novel human-purified type I collagen membrane from bone remnants typically discarded during the processing of cortico-cancellous bones in tissue banks and to evaluate its mechanical properties and effectiveness in regenerating bone-critical mandibular defects in rabbits. To prepare the novel membrane, cortico-cancellous bone chip samples from a local tissue bank were processed to isolate collagen by demineralization under agitation in HCl, cast into a silicone mold, and air-dried at room temperature and UV irradiation. The average thickness of the four batches analyzed by SEM was 37.3 μm. The average value of Young’s modulus and tensile strength obtained from the specimens was 2.56 GPa and 65.43 Mpa, respectively. The membrane’s efficacy was tested by creating a critical bicortical and bilateral osteoperiosteal defect in rabbit mandibles. The right-side defects were covered with the collagen membrane, while the left-side defects were left untreated as a control. Nine weeks post-surgery, clinical, radiological, and histological analyses demonstrated new bone formation in the treated areas, whereas the control sites showed no bone regeneration. This innovative approach not only contributes to sustainability in healthcare by optimizing biological waste but also exemplifies efficient resource use in line with the circular economy, offering a cost-effective, biocompatible option that could benefit national health systems.

Coordinating uncertainty in the political economy of cyber threat intelligence.

Cyber threat intelligence firms play a powerful role in producing knowledge, uncertainty, and ignorance about threats to organizations and governments globally. Drawing on historical and ethnographic methods, we show how cyber threat intelligence analysts navigate distinctive types of uncertainty as they transform digital traces into marketable products and services. We make two related contributions and arguments. First, building on STS research on uncertainty and ignorance, we articulate two kinds of uncertainty and their potential to interact. Coordinative uncertainty emerges from socially and technologically distributed processes of producing, interpreting, and reporting data that emerges when analysts create standards to make data travel. However, standards can be exploited by intelligent adversaries behaving in deliberately unpredictable ways. We argue that efforts to reduce coordinative uncertainty through standardization can thus ironically increase opportunities for adversarial uncertainty, creating a potential tradeoff. Second, we aim to show how STS can deepen and integrate studies of international security and political economy, by providing an example of how the geopolitical structuring of private industry shapes the science and technology that industry produces. In particular, we argue that the political economy of the cyber threat intelligence industry tends to produce relatively little knowledge about cyber operations that are conducted by governments in the U.S. and its allies, and more about cyber operations conducted by adversaries of U.S. and allied governments. We conclude with a reflection on the broader significance of these findings for the ways that coordinative and adversarial uncertainties refract through the political economies of technoscience.

Gridded drought response assessment of winter wheat in Oklahoma using big data and AquaCrop-OS.

Winter wheat is the most dominant crop in Oklahoma and critically important to the economy of agricultural industry in this state and the region. However, weather anomalies such as droughts, which are frequent in Oklahoma, pose serious threats to winter wheat yield. This study was conducted to assess the effects of droughts on the simulated yield of dryland winter wheat (Ysd) in Oklahoma employing a gridded approach with the AquaCrop Open Source (AquaCrop-OS). Long-term (30-year) simulations showed that the average Ysd ranged from 0.9 to 7.1Mgha-1 across the 3281 grids of the Oklahoma winter wheat belt. At the climate division level, Ysd ranged from 2.9Mgha-1 in Panhandle to 5.5Mgha-1 in Central divisions. Fluctuation in Ysd generally agreed with the actual dryland yield measured at several research fields across the study area. However, the model tended to underestimate Ysd during certain drought events at some sites. The coefficient of variation (CV) for Ysd ranged from 0.1 to 1.6. Panhandle climate division had the largest CV, mainly due to inconsistency in growing season precipitation and temperature related stresses. In addition, grids with smaller total available water in the root zone, such as those with coarser textures near streams, had lower yields and larger CV. The strongest correlations between Ysd and drought indices (SPEI, Z-index, PDSI) existed in the months of March to May, when the crop is highly sensitive to water stress. Largest drought sensitivity of winter wheat, based on Ysd-drought index regression slopes, was estimated in West Central division for short to long-term droughts.

THE IMPACT OF MOTIVATIONS ON BEHAVIORAL INTENTIONS IN THE SHARING ECONOMY

This study examines the motivations that impact individuals’ behavioral intentions (BI) to participating the sharing economy in the tourism industry. Based on existing literature, the study develops a conceptual framework to test the research hypotheses that encompasses six major motivations: economic benefits, sustainability, enjoyment, reputation, trust, and privacy. For this purpose, the quantitative research method is preferred and the data was collected through a face-to-face survey questionnaire from 398 locals in Istanbul with experience of using Airbnb. As a result of the study, the proposed Sharing Economy Motivation Scale (SEMS) is confirmed using factor analysis. The results of the path analysis also revealed that, all six motivations have a significant direct and positive influence on behavioral intention. In fact, trust emerged as the most influential motivation to behavioral intention, followed by privacy, enjoyment, sustainability, economic benefits and reputation. The research findings contribute to a greater understanding of the motivations behind participation in the sharing economy in tourism industry.

In-kind Wages: Understanding Workers’ Strategies to Cope with Inflation and Poverty

Abstract Although non-monetary benefits remain an important component of most workers’ wages in today's industrial economies, development economists and economic historians tend to view such payments as a remnant of older, obsolete labour regimes. But when in-kind wages are assumed to be exploitative, an outcome of market inefficiencies, or simply the result of limited supply of coinage, their actual economic functions can be obscured. Once we drop the constraints imposed by such assumptions and look at the historical evidence, we are forced to confront the possibility that workers actually used them to their advantage. In this article, I analyse how in-kind wages functioned in certain historical contexts, and conclude that available explanations are far too limited. As the historical cases studied show, the different forms of in-kind payments must be examined because those forms – not just overall wage levels – helped determine labour supply, social and occupational mobility, and even capital formation. The goods and services that made up in-kind payments also provide a fuller understanding of gender wage gaps. Non-monetary wages gave workers options that cash wages did not, and so created and reproduced fundamental inequalities among different groups.

A Study of the Quantitative Impact of Different Credit Policies on Real Estate Price Volatility in the Housing Finance Market

Real estate industry is an important industry of national economy in any country, which constitutes an important element of the wealth of the whole society and has a stable and long-term impact on national economy and social development. Based on the price theory of supply-demand equilibrium and the theory of real estate cycle fluctuation, the article combines the stock-flow model and vector autoregression model of real estate price to establish a quantitative analysis PVAR model of credit policy on real estate price fluctuation. Data from 31 provincial regions in China from 1998 to 2023 are selected as the research samples, and the specific effects of different credit policies on real estate price volatility in the housing finance market are verified through empirical analysis. When the scale of credit policy expands by 1 percentage point, real estate prices will increase by 0.00611 percentage points, while credit interest rates have a positive impact on real estate price volatility for 6 to 7 periods, and then change to a negative impact. Different regions under the credit policy on real estate price volatility there are differences, and the faster the growth rate of real estate prices in the region credit policy on real estate prices to promote the role of the more obvious. Real estate price regulation needs to accurately combine regional and economic development, so as to optimize the credit policy of the housing finance market, and then ensure the stability of real estate prices.

The Impacts of Digital Economy on the Digital Transformation of Small and Medium-sized Enterprises

Digital economy, as a new economic model after agriculture and industrial economy, is rising rapidly and gradually, becoming the main economic form of current society. This economic model is based on Internet information technology and regards big data as a core production factor. The digital economy contributes significantly to resource allocation optimization and the transformation of traditional sectors through precise identification and deep integration of data resources. In the meantime, small and medium-sized businesses, which are a significant component of the national economy, consistently hold a significant position in employment and technical innovation. The trend of small and medium-sized businesses going digital has become unavoidable in order to keep up with the growth of the digital economy. The purpose of this paper is to examine how the digital economy affects small and medium-sized businesses' digital transformations and to examine the relationship, present state, and difficulties between the two. The specific effects of the digital economy on the transformation of small and medium-sized businesses from the perspectives of production process, operation management, and product services, as well as the opportunities and difficulties posed by digital transformation, are then discussed in order to offer helpful resources and motivation for this process.

Barriers and Strategies in Implementing Design for Disassembly and Adaptability Principles in Singapore: A Pathway to Circular Economy in the Construction Industry

ABSTRACTAs sustainability becomes crucial in the global construction industry, Design for Disassembly and Adaptability (DfDA) principles are key to advancing a circular economy by reducing waste, conserving resources, and enhancing building adaptability. In Singapore, with its high‐density urban landscape and limited natural resources, the adoption of DfDA principles is especially vital to ensure long‐term environmental and economic resilience. This study investigated barriers to DfDA implementation in Singapore's construction industry, analyzed strategies to address these challenges, and examined differences in perceptions based on professional roles and experience through a literature review, a questionnaire survey, and interviews. Eleven barriers and eight strategies were identified. The top barriers included the lack of practical tools and guidelines, cost and schedule constraints, and negative public perception of reused building components. The most effective strategies included providing financial incentives and awards, developing explicit guidelines and frameworks, and promoting collaborative project delivery methods. Significant differences were observed in perceptions based on respondents' roles and experience. This study advances theoretical understanding by developing a novel systematic framework that integrates barriers and strategies for DfDA implementation and stakeholder dynamics in the construction industry. The findings provide practical guidance for developing targeted measures to promote sustainable building practices. These insights significantly contribute to advancing industry‐wide sustainability initiatives and global sustainable development goals.

Diasporic Capital: Canadian Sex Workers of Color Hacking Sexual Racism

The cultural economy of the contemporary Canadian sex industry, particularly the upscale sectors, requires workers to conform to white aesthetics and gestures in conscious attempts to generate desire among white consumers. This article, drawing on a qualitative study, posits Canadian sex workers of color as a critical point of inquiry to understand how they negotiate market expectations against the backdrop of popular representation of, for example, the “Jezebel,” “Sapphire,” the Dragon lady, and the Bollywood Queen. Sex workers of color in my sample are mostly immigrant women and Canadian women with full or partial ancestry in a foreign country. Drawing attention to research participants’ immaterial and intimate labor practices, which include emotional and aesthetic labor processes, I examine how these sex workers of color utilize diasporic capital to juxtapose dominant gender-, class-, and citizenship-based negative controlling images against sexual racism. Such labor practices involve negotiating their multiple, fluid, and overlapping identities as the workers unapologetically celebrate and revalorize their diasporic identities and cultures. Strategically mobilizing economic, social, cultural, and symbolic capital facilitates the transformation of their body capital to establish a minority niche within the contemporary sex markets.

Sustainable Alkali-Activated Self-Compacting Concrete for Precast Textile-Reinforced Concrete: Experimental-Statistical Modeling Approach.

Industrial and construction wastes make up about half of all world wastes. In order to reduce their negative impact on the environment, it is possible to use part of them for concrete production. Using experimental-statistical modeling techniques, the combined effect of brick powder, recycling sand, and alkaline activator on fresh and hardened properties of self-compacting concrete for the production of textile-reinforced concrete was investigated. Experimental data on flowability, passing ability, spreading speed, segregation resistance, air content, and density of fresh mixtures were obtained. The standard passing ability tests were modified using a textile mesh to maximize the approximation to the real conditions of textile concrete production. To determine the dynamics of concrete strength development, compression and flexural tests at the ages of 1, 3, 7, and 28 days and splitting tensile strength tests of 28 days were conducted. The preparation technology of the investigated modified mixtures depending on the composition is presented. The resulting mathematical models allow for the optimization of concrete compositions for partial replacement of slag cement with brick powder (up to 30%), and natural sand with recycled sand (up to 100%) with the addition of an alkaline activator in the range of 0.5-1% of the cement content. This allows us to obtain sustainable, alkali-activated high-strength self-compacting recycling concrete, which significantly reduces the negative impact on the environment and promotes the development of a circular economy in the construction industry.

Research on the strategic choice behavior of green building interest subjects based on evolutionary game

As a mainstay industry of national economy, construction brings a country huge benefit, et along with significant amount of pollution to environment. In the age of sustainable development, green building (GB) can greatly reduce pollution caused by the construction industry. To study the evolution of stakeholders engaged in China’s green building implementation, this paper designed a three-party game model including government, developer, and consumer, analyzed the stability of the model and obtained the evolutionary stability strategy. This paper also used green building data in China to conduct numerical simulation, including sensitive analysis to explore key factors affecting the game subjects, and phase diagrams and bifurcation diagrams to analyze influence of parameter change to the evolutionary stabilization strategy (ESS). The results show that (1) in the long term, the government will choose the regulatory strategy when the cost of government regulation is below one-third of the financial subsidy; (2) the probability of developers and consumers choosing the green building strategy is negatively correlated to the cost and positively correlated to the benefit; (3) the primary determinant behind customers’ decision to purchase a green building revolves around the enhanced quality of life that such buildings offer.

Kebijakan Industri Menghadapi Globalisasi

Industrial policy in Indonesia faces significant challenges in an era of increasingly complex globalization. Globalization brings great opportunities for domestic companies to compete globally, but also poses risks such as economic inequality and unemployment. To address these challenges, the government needs to develop a smart industrial policy that not only encourages sectoral growth but also stimulates cross-sectoral innovation. Selecting imported goods, imposing high import fees on commodities that can already be produced domestically, and providing capital injections to companies with comparative advantages are effective ways to protect local industries from the negative impacts of globalization. Digitalization must also go hand in hand with the implementation of this strategy so that sectors can use digital technology to increase productivity and create new economic opportunities, especially for micro, small, and start-up businesses. Furthermore, Indonesia's economic strength in navigating the problems of globalization may lie in its integration with the creative economy. Indonesia's industrial economy requires creative and innovative human resources so that the creative sector can develop and compete on a global scale.
