Intangible Heritage and Local Development the Case of the Casbah of Algiers

Intangible heritage occupies a central place in society as a witness to the traditions and customs handed down byprevious generations. Beyond its cultural dimension, it is an essential means of reinforcing a sense of belonging,sustaining human creativity and revitalizing socio-cultural groups. However, its importance is not limited to simplypassing it on to future generations. This heritage also plays a fundamental role in the sustainable development of thetourism sector and, consequently, the national economy. It is therefore imperative to explore innovative strategies toenhance this heritage while preserving the cultural integrity of communities. The Casbah of Algiers was chosen as anexemplary case study. In-depth surveys were carried out with visitors, cultural associations and tourism agencies. Inaddition, we adopted an economic analysis methodology known as the "contingent valuation method", which enabledus to assess the economic value of the intangible heritage of the Casbah of Algiers. Based on these results, we are ableto propose strategic recommendations for intensifying the conservation of intangible cultural heritage andencouraging sustainable tourism. These recommendations could include awareness-raising actions, training initiatives,collaboration with local stakeholders and targeted marketing campaigns. By promoting intangible heritage, we fostereconomic prosperity while preserving.

Biodegradable and Ultra-High Expansion Ratio PPC-P Foams Achieved by Microcellular Foaming Using CO2 as Blowing Agent.

Poly(propylene carbonate-co-phthalate) (PPC-P) is an amorphous copolymer of aliphatic polycarbonate and aromatic polyester; it possesses good biodegradability, superior mechanical performances, high thermal properties, and excellent affinity with CO2. Hence, we fabricate PPC-P foams in an autoclave by using subcritical CO2 as a physical blowing agent. Both saturation pressure and foaming temperature affect the foaming behaviors of PPC-P, including CO2 adsorption and desorption performance, foaming ratio, cell size, porosity, cell density, and nucleation density, which are investigated in this research. Moreover, the low-cost PPC-P/nano-CaCO3 and PPC-P/starch composites are prepared and foamed using the same procedure. The obtained PPC-P-based foams show ultra-high expansion ratio and refined microcellular structures simultaneously. Besides, nano-CaCO3 can effectively improve PPC-P's rheological properties and foamability. In addition, the introduction of starch into PPC-P can lead to a large number of open cells. Beyond all doubt, this work can certainly provide both a kind of new biodegradable PPC-P-based foam materials and an economic methodology to make biodegradable plastic foams. These foams are potentially applicable in the packaging, transportation, and food industry.

Economic valuation of Harmful Algal Blooms (HAB): Methodological challenges, policy implications, and an empirical application

This paper presents a literature review on the economic valuation of Harmful Algal Bloom (HAB) impacts, identifying methodological challenges, policy implications, and gaps. Unlike previous literature reviews, we are particularly interested in determining whether the economic valuations of HABs have included a policy analysis. Our paper provides a conceptual framework that allows us to evaluate whether applications of economic studies of HABs are consistent with a well-defined economic welfare analysis. It links methodologies and techniques with welfare measures, data types, and econometric methods. Based on this literature review, we present an example of economic valuation that closes the gap between policy analysis and valuation methodology. We use a stated preferences study to estimate a “seafood price premium” to create a fund to support monitoring systems and for damage compensation to producers in the presence of HABs. Results show that most economic studies on HAB valuation do not consider any cost-benefit analysis of a defined policy intervention. The predominant economic valuation methodology uses market information to estimate a proxy for welfare measure of the impact of HABs (loss revenue, sales, exports). Moreover, nonuse and indirect use values are ignored in the literature, while stated preference methodologies are underrepresented. Finally, results from 1293 surveys found that people are willing to pay an increase in the price of mussels to support a policy that informs on HAB. However, the lack of institutional trust affects the probability of paying negatively.

The Future of Innovative Agriculture: Bioeconomy and Sustainable Agriculture

Innovative farming techniques are essential for food security and sustainable farming practices. Innovative agricultural approaches utilize modern technologies and the latest inventions, as well as traditional agricultural practices. The main purpose of this study is to address the relationship between sustainable agriculture and bioeconomy and to examine innovative approaches that are expected to have a significant impact on the agricultural sector in the near future. The study was carried out in compilation format. Bioeconomy is an economic model or methodology based on the economic evaluation of biological resources and processes. Abiotic resources such as microbes, vegetation, animals, and biodiversity are all included in this strategy. On the other hand, sustainable agriculture, which aims to protect natural resources and take into account ecosystem benefits while maintaining food production, is an agricultural paradigm. The primary goals of bioeconomy and sustainable agriculture are economic evaluation, efficient use of natural resources and reduction of environmental impacts. Considered from these perspectives, it can be said that both concepts have common purposes and are closely related. It is possible to say that with the increasing use of sustainable agricultural methods and bioeconomy, the agricultural sector can move towards a more environmentally friendly, efficiently managed and sustainable structure in the future.

A green micelle-enhanced first derivative synchronous fluorescence approach for determination of donepezil HCl and trazodone HCl in their pure state, pharmaceutical dosage form and spiked human plasma.

The study's objective is to establish an eco-friendly, sensitive and economical quantitative methodology for the concurrent analysis of donepezil HCl (DPZ) and trazodone HCl (TRZ) in raw materials, tablets and human plasma. The first derivative synchronous fluorescence spectroscopic (FDSFS) technique was applied at constant wavelength difference (∆λ = 120) for assessment of DPZ and TRZ at each other's zero-crossing point at 279 nm and 297 nm, respectively. The submitted technique was validated in accordance with ICH Q2 R1 guidelines and the linearity of the standard calibration curve was observed over the concentration range of 10-500 ng/ml for DPZ and 20-1,000 ng/ml for TRZ. The detection limits (LOD) were found to be 2.65 and 5.4ng/ml, and the limits of quantitation (LOQ) were 8.05 and 16.3ng/ml for DPZ and TRZ, respectively. This technique was used further to quantify the studied medications in their laboratory-prepared mixtures, commercial tablets and spiked plasma samples. The results obtained were not significantly different from those acquired from the comparison methods, indicating the high accuracy and precision of the proposed method. Furthermore, the ecological friendliness of the suggested method was evaluated and proven to be excellent using Green Analytical Procedure Index (GAPI) and Analytical GREEnness (AGREE) evaluation tools.

End-Of-Life Management of Photovoltaic Panels: A Model for Forecasting and Economic Evaluation

The global surge in photovoltaic (PV) panel deployment since the 2000s has contributed to advancing the renewable energy sector. However, this proliferation raises concerns about the increasing number of PV modules that will end their operational life in the coming years, necessitating effective planning for their decommissioning and recovery. This paper addresses this imminent challenge by presenting a predictive model to estimate the volume of decommissioned modules from existing installations. To take into account the variability associated with the operational life duration of PV panels, three distinct scenarios were considered: early loss, regular loss (both modelled through the Weibull function) and fixed loss. Furthermore, the article introduces a methodology for the economic valorisation of materials recovered from decommissioned PV modules, according to the different technologies employed. This approach encourages sustainable practices by assigning an economic value to recovered materials, promoting a circular economy in the renewable energy sector. The economic valuation methodology adds practicality to dismantling, emphasising responsible waste management's potential economic benefits. In order to illustrate the applicability of the model, the study focuses on the Italian case, providing a detailed regional breakdown. The regional analysis not only improves the accuracy of the predictive model but also offers insights into localised PV module disposal patterns. By adapting the model to the individual Italian regions, the article serves as a concrete and valuable resource during the programming and planning phases, facilitating the implementation of a strategy to efficiently recover PV modules and consequently minimising the environmental impact associated with decommissioning activities.

Practical Evaluation of Ionic Liquids for Application as Lubricants in Cleanrooms and under Vacuum Conditions

As part of a publicly funded cooperation project, novel high-performance lubricants (oils, greases, assembly pastes) based on ionic liquids and with the addition of specific micro- or nanoparticles are to be developed, which are adapted in their formulation for use in applications where their negligible vapor pressure plays an important role. These lubricants are urgently needed for applications in cleanrooms and high vacuum (e.g., pharmaceuticals, aerospace, chip manufacturing), especially when the frequently used perfluoropolyethers (PFPE) are no longer available due to a potential restriction of per- and polyfluoroalkyl substances (PFAS) due to European chemical legislation. Until now, there has been a lack of suitable laboratory testing technology to develop such innovative lubricants for extreme niche applications economically. There is a large gap in the tribological test chain between model testing, for example in the so-called spiral orbit tribometer (SOT) or ball-on-disk test in a high-frequency, linear-oscillation test machine (SRV-Tribometer from German “Schwing-Reib-Verschleiß-Tribometer”), and overall component testing at major space agencies (ESA—European Space Agency, NASA—National Aeronautics and Space Administration) or their service providers like the European Space Tribology Laboratory (ESTL) in Manchester. A further aim of the project was therefore to develop an application-orientated and economical testing methodology and testing technology for the scientifically precise evaluation and verifiability of the effect of ionic liquids on tribological systems in cleanrooms and under high vacuum conditions. The newly developed test rig is the focus of this publication. It forms the basis for all further investigations.

Phenomenology and intersubjectivity in political economy: an anti-perfectionist perspective

Anti-perfectionism is a philosophical perspective combining the view of man as an imperfect and non-self-sufficient being with a scientific epistemology based on imperfect knowledge. From an epistemological perspective, it has roots in Socrates and, more recently, in the post-empiricism of Giambattista Vico, up to phenomenology. From an anthropological perspective, it is a philosophical tradition based on an awareness of the constitutive dependency of individual performance and fulfilment of man on his interaction with others. It is conceived in opposition to the individualism and perfect rationality of most social theories. The paper analyses both the philosophical and the epistemological premises of anti-perfectionism as well as its consequences in terms of economic methodology. It will specifically develop the momentary intersection of phenomenology and Austrian economics. The theory of knowledge and of sense-making of phenomenology will be discussed with particular attention to intersubjectivity, which expresses anti-perfectionism well. The interpretations of human knowledge and action of Scheler and Schütz are analysed and connected to some contemporary streams of Austrian economics.

Institutional Approach in Economics and Institutional Economic Thinking

Aspects of economic methodology contained in Institutional economics are often incorporated into orthodox economics. Orthodox economics means economic thoughts that use and continue classical economic views, such as free competition, perfect competition, consumer satisfaction. The person who was most influential and had a dominant role in the existence of the Institutional school was Thorstein Bunde Veblen. He criticized Classical and Neo-classical economic theories which ignored non-economic aspects such as institutions and the environment. In fact, Veblen considered that the influence of circumstances and the environment was very large on people's economic behavior. Unsupportive political and social structures can cause distortions in economic processes. For Veblen, society is an evolutionary phenomenon, everything is constantly changing. A person's behavioral patterns in society are adapted to current social conditions. If the behavior is suitable and accepted, then the behavior will continue. On the other hand, if a behavior is deemed unsuitable, the behavior will be adapted to the environment. These circumstances and environments are what Veblen called "institutions". In this case, it is explained that what Veblen means by institutions are things related to norms, values, habits and culture. Furthermore, everything is reflected in economic activities, both in production and consumption.

Financial and economic costs of healthcare-associated infections in Africa

Healthcare associated infections (HAI) remain a global health challenge and have elevated rates in Sub-Saharan Africa. HAIs impact patients and their families by causing illness, prolonged hospital stay, potential disability, excess costs and sometimes death. The costs of HAI are increasing due to spreading antimicrobial resistance. A major risk factor for HAIs is lack of water, sanitation, and hygiene (WASH), environmental cleaning and healthcare waste management. In Sub-Saharan Africa these services are lacking in at least 50% of healthcare facilities. This study estimated the costs associated with HAIs at national level in fourteen countries in Sub-Saharan Africa. Economic methodologies were employed to estimate the medical costs, productivity losses and value of premature death from HAIs, drawing on national statistics and published studies to populate the economic model. In 2022, the number of HAIs was estimated at 4.8 million, resulting in 500,000 deaths. Health-related economic losses amounted to US$13 billion per year, equivalent to 1.14% of combined GDP and US$15.7 per capita. Healthcare costs were US$500 per HAI and represented 5.6% of total health expenditure. The costs of providing basic WASH were US$0.91 per capita, which, if they reduced HAIs by 50%, resulted in benefit-cost ratios of 1.6 (financial health care savings only) and 8.6 (including all economic benefits). HAIs have a major health and economic burden on African societies, and a significant share can be prevented. It is critical that health policy makers and practitioners dedicate policy space, resources, and training to address HAIs.

Cost identification in health professions education: A scoping review.

Resource scarcity in health professions education (HPE) demands rigorous consideration of costs. Yet, thus far, we have been unable to completely and consistently identify the costs of HPE. To address this knowledge gap and enable use of economic evidence in decision making, a detailed overview of all existing costs and approaches to cost identification in HPE is needed. This review summarises the diversity of costs, cost perspectives and cost identification methods used in economic research of HPE to answer the following questions: which educational topics, costs, cost perspectives and cost identification methods are being investigated in HPE literature? This investigation followed the Joanna Briggs Institute guidelines for scoping reviews. PubMed, ERIC, CINAHL and PsycINFO were iteratively searched for English language publications between 2012 and 2022 that reported costs of HPE. Data was extracted for study characteristics, educational context and economic methodology. A total of 136 articles of original research on the costs of educating all major licence healthcare professionals were included. A diffuse interest in costs is reflected in publications from 93 distinct journals and by the diversity of educational topics and cost types explored. However, the majority of investigations failed to define the cost perspective (86, 63%) and cost identification methods (117, 86%) and did not demonstrate common reporting structure or cost terminology, all of which contribute to persistent inconsistencies in cost identification. The source of disharmonious cost identification in HPE is fuelled by diverse interests and divergent concepts of costs and costing methodology. Left in its current state, disharmonious cost identification will continue to limit transparency, comparison and synthesis of evidence, hamper objectivity in implementation and policy decisions and impede the efficient and sustainable allocation of resources. A research agenda must be developed, prioritised, and validated by the broader community to develop a theoretical framework for HPE cost research, define stakeholders, elicit values and preferences and chart a path toward harmonised costing.

Robust Enhancement of Direct Air Capture of CO2 Efficiency Using Micro-Sized Anion Exchange Resin Particles

In the quest to mitigate carbon dioxide emissions, it becomes essential to address the existing atmospheric CO2. Effective and economical methodologies, particularly those without additional energy consumption, are crucial. Currently, a leading method is the direct capture of CO2 using ion exchange resins, which achieve the adsorption and desorption of carbon dioxide simply by using the humidity variations. This technology, though minimizing additional energy cost, still needs improvement in its efficiency in CO2 capture capacity and compared to other methods. In this work, we develop low-cost techniques to reduce the AmberLite™ IRA900 Cl (IRA-900) anion exchange resin to micro size, and observe significant performance enhancement on CO2 capture efficiency contingent on reducing the particle diameters. This performance disparity is attributed to the differential water adsorption capacities inherent in particles of diverse diameters. Our results reveal that smaller resin particles outperform their larger counterparts, exhibiting accelerated adsorption rates and expedited transitions from wet to dry states. Notably, these smaller particles display a quintupled enhancement in adsorption efficacy relative to non-treated particles and a marked increase in relative adsorption capacity. Upon treatment, IRA-900 demonstrates robust CO2 processing efficiency, achieving a peak adsorption rate of 1.28 g/mol·h and a maximum desorption rate of 1.18 g/mol·h. Also, the material is subjected to almost 100 cycles of testing, and even after 100 cycles, the resin particles maintain a capacity of 100%. Moreover, our material can be fully regenerated to 100% efficiency by simply immersing it in water. Simultaneously, storing it in water allows for the long-term maintenance of its performance without other treatment methods. A key observation is the resin’s sustained performance stability post extended exposure to humid conditions. These outcomes offer substantial practical implications, emphasizing the relevance of our study in practical environmental applications.

SDEWES 2023: Barriers and Possibilities for the Development of Short-Rotation Coppice as an Agroforestry System for Adaptation to Climate Change in Central European Conditions

This article compares different production, economic, and selected environmental aspects of agroforestry systems in a standard (alley cropping) and a newly proposed design with fast-growing trees grown in short-rotation coppice. Our models of agroforestry systems (AFSs) are as follows: (i) alley cropping AFS with cherry and walnut trees in single rows (tree strips) with 28 m-wide arable fields between them (crop strips), and (ii) coppiced tree belt AFS with poplars and willows and 25 m-wide arable fields between them (crop strips). To evaluate the production characteristics of trees, we used yield curves from experimental plantations in conditions of the Czech Republic from previous research projects. Cost data were collected from long-term experimental plantations and combined with current operation and energy prices. The article presents an economic methodology for assessing the competitiveness of biomass production in AFSs under the current identified market conditions. Our results show that AFSs with short-rotation coppice can have similar economic and production results as annual crops if grown on suitable sites and with appropriate quality of agronomy. In comparison, alley cropping AFSs with fruit trees would not be economically viable for farmers without a significant subsidy for establishment and maintenance in the first years after establishment. Concerning the latest economic and political developments, the product from SRC (energy woodchips) can be evaluated as strategic, increasing the producer’s independence from purchased energy fuels.

Impact Analysis of High-Altitude Electromagnetic Pulse Coupling Effects on Power Grid Protection Relays

Protection relays are important equipment used for protection, control, and metering functions in the power grid. These relays are used to protect critical and difficult-to-replace equipment, like generators, transformers, and capacitor banks. Once the protection devices are disturbed or damaged, a high risk of power generation interruption occurs. Therefore, it is important and necessary to study the relay’s immunity to electromagnetic pulse (EMP) events. As a preliminary step toward empirical experimentation on actual equipment, this manuscript outlines an economical and efficient methodology for evaluating the impact of an EMP. An impedance measurement strategy was employed to model the equipment, setting the stage for subsequent immunity analyses. These analyses included the pulse current injection (PCI) method, which utilized an injecting probe to introduce the transient, and frequency domain electromagnetic (FEKO) simulation, which integrated electromagnetic coupling effects into the transient simulation. The impedance measurement and simulation results in this paper provide a reliable basis for gauging equipment performance in the face of HEMP threats. The results obtained using the PCI and FEKO simulations demonstrated the performance of different port responses under a high-altitude EMP, indicating the requirement for some protection to ensure the reliable operation of relays.

The results show that the stage of hydrogen-rich gas prepared by FCOP of biomass is an important factor affecting energy output and input, and has the highest standard pollutant emissions (92.11%). This process has low carbon emissions and GHG emissions, showing good sustainability and application prospects, which has important guiding significance for realizing cleaner production and solving the energy crisis. Thirdly, taking the large-scale system of producing hydrogen-rich gas co-production biochar, which processes 40,000 t of CS per year, as an example, the economic benefit analysis results were obtained, that is, IRR, NPV, and Pm are 22%, 6.33 million yuan, and 7.3 years, respectively. Meanwhile, the key factors, including the initial investment, expenses of biomass and catalyst, and the sale income of hydrogen and biochar, which are the main factors affecting the economic efficiency of technology, and uncertainties were identified through sensitivity analysis. Finally, we put forward in the background of ecological civilization, the research focus and thinking for the development of hydrogen production technology from pyrolysis/gasification of biomass were proposed. The results obtained can be valuable in practical applications to enhance the sustainability and viability of hydrogen production in biomass conversion and utilization activities. The applied energy, economic, and environmental methodologies appear to be reliable and comprehensive tools for assessing the whole-life sustainability and viability of biofuel.

Determination of Lead in Bee Products by Solid Surface Fluorescence Using Complexation and Coacervation at Room Temperature Processes. An Environmental Friendly Methodology.

An accurate, economic and green methodology for Pb(II) monitoring in bee products is proposed. Complexed metal traces were preconcentrated on Nylon membranes using the coacervation phenomenon based on room temperature reaction between the cationic surfactant hexadecyltrimethylammonium bromide and the bile salt sodium cholate. The increase in solid surface fluorescence signal of dyes 8-hydroxyquinoleine and o-phenanthroline due to Pb(II) presence was used for the metal quantification. Experimental variables that influence on preconcentration step and fluorimetric sensitivity were optimized using uni-varied assays. Pb(II) concentration was determined on membranes by solid surface fluorescence at λem = 470nm (λexc = 445nm), using a solid sample holder. The calibration at optimal experimental conditions showed a LOD of 4.2 × 10-4mg Kg-1 with a linear range of 1.28 × 10-3mg Kg-1 to 8.73mg Kg-1 and was successfully applied to Pb(II) quantification in different bee products produced in central west region of Argentina. The proposed methodology was applied to all samples after appropriate dilution. Accuracy methodology was evaluated by comparison of the obtained results with those found by ICP-MS, with percentage relative error under 8%. The precision was better than 0.0344 CV for Pb(II) determination.

The influence of femicide on criminal behavior: An empirical approach using economic complexity for crime prevention in Mexico

Following the economic complexity methodology introduced by Hausmann et al. (2013), this study establishes an order of crime evolution in Mexico. This ordering is based on the complexity of crimes, as determined by the capabilities required to commit them. According to the study, the least complex crimes in Mexico include robbery in collective public transport, robbery in individual transport, counterfeiting, and auto parts theft. On the other hand, the crimes characterized by the highest complexity involve organized crime, intentional and unintentional homicide, and the trafficking of minors. Furthermore, the analysis reveals that femicide and rape exhibit the most significant centrality or influence within the criminal network. According to the model, crimes associated with violence against women are those that most increase the probability of committing another crime. Therefore, targeted prevention efforts aimed at reducing femicide and rape may substantially impact overall levels of criminality in Mexico. This study also highlights the importance of addressing violence against women in designing crime prevention policies in Mexico. Moreover, the methodology adopted in this study can be reinterpreted as a spectral clustering algorithm and thus also contributes to the literature on machine learning applications in public policy design.

Influence of interactions between bubbles on physico-chemical effects of acoustic cavitation

Ultrasound technology has been extensively used as one of the efficient and economic methodology to achieve the desired outcomes in many applications by harnessing the physico-chemical effects of acoustic cavitation. However, the cavitation-associated effects, primarily determined by the oscillatory dynamics of cavitation bubbles, are considerably complex and still remain poorly understood. The main objective of this study was to perform a numerical analysis of the acoustic cavitation (i.e., the cavitation dynamics, the resultant temperature, pressure and chemical yields within collapsing bubbles), particularly focusing on the influence of the interactions between bubbles. A comprehensive model was developed to simulate the acoustic cavitation dynamics via combining the influences of mass transfer, heat conduction and chemical reactions as well as the interaction effects between bubbles. The results demonstrated that only the large bubble exerts a greater impact on the small one in a two-bubble system. Specifically, within parameter ranges covered this study, there are noticeable decreases in the expansion ratio of the small bubble, the resultant temperature, pressure and molar yields of free radicals, hence weakening the cavitation intensity and cavitation- associated physico-chemical effects. Moreover, the influences of the interactions between bubbles were further assessed quantitatively under various parameters, such as the ultrasound amplitude PA and frequency f, the distance between bubbles d0, the initial radius of the large bubble R20, as well as the liquid properties (e.g., surface tension σ and viscosity μ). It was found that the suppression effect can be amplified when subjected to ultrasound with an increased PA and/or a decreased f, probably due to a stronger cavitation intensity under this condition. Additionally, the suppression effect is also enhanced with a decrease in d0, σ and μ, but with R20 increasing. This study can contribute to deepening knowledge about acoustic cavitation and the resultant physical and/or chemical effects, potentially further facilitating the ultrasound-assisted various applications involving acoustic cavitation.
