Association of Carotid Artery Disease with Collateralization and Infarct Growth in Patients with Acute Middle Cerebral Artery Occlusion.

Collaterals are important in large vessel occlusions (LVO), but the role of carotid artery disease (CAD) in this context remains unclear. This study aimed to investigate the impact of CAD on intracranial collateralization and infarct growth after thrombectomy in LVO. All patients who underwent thrombectomy due to M1 segment occlusion from 01/2015 to 12/2021 were retrospectively included. Internal carotid artery stenosis according to NASCET was assessed on the affected and nonaffected sides. Collaterals were assessed according to the Tan score. Infarct growth was quantified by comparing ASPECTS on follow-up imaging with baseline ASPECTS. In total, 709 patients were included, 118 (16.6%) of whom presented with CAD (defined as severe stenosis ≥70% or occlusion ipsilaterally), with 42 cases (5.9%) being contralateral. Good collateralization (Tan 3) was present in 56.5% of the patients with ipsilateral CAD and 69.1% of the patients with contralateral CAD. The ipsilateral stenosis grade was an independent predictor of good collateral supply (adjusted OR: 1.01; NASCET point, 95% CI: 1.00-1.01; P = .009), whereas the contralateral stenosis grade was not (P = .34). Patients with ipsilateral stenosis of ≥70% showed less infarct growth (median ASPECTS decay: 1; IQR: 0-2) compared with patients with 0%-69% stenosis (median: 2; IQR: 1-3) (P = .005). However, baseline ASPECTS was significantly lower in patients with stenosis of 70%-100% (P < .001). The results of a multivariate analysis revealed that increasing ipsilateral stenosis grade (adjusted OR: 1.0; 95% CI: 0.99-1.00; P = .004) and good collateralization (adjusted OR: 0.5; 95% CI: 0.4-0.62; P < .001) were associated with less infarct growth. CAD of the ipsilateral ICA is an independent predictor of good collateral supply. Patients with CAD tend to have larger baseline infarct size but less infarct growth.

Globalização, empresa e responsabilidade socioambiental

The research addresses the globalization’s issue and socio-environmental responsibility of Brazilian companies concerning to adoption of ethical standards and business commitment based on the criteria of Environmental, Social and Corporate Governance, concepts that support the new process of internationalization of business law, globally. This is a systematic interpretation of the corporate production of wealth with emphasis of globalization for a better understanding of the role of the modern company which, in addition to being a supplier of goods and services, must be allied to socio-environmental interests with the creation of new markets, generating jobs and attracting new consumers. As a basis, scientific and bibliographical productions by Brazilian and international authors were researched. It is clear to conclude that there is a need for public policies to promote environmental education and social accountability of all Brazilian business people and thus guarantee the preservation and protection of the sustainable environment through the search for social and ethical values in defense of the global ecosystem.

ADMINISTRATIVE AND LEGAL REGIME OF THE NORTHERN DELIVERY AS A FACTOR OF SUSTAINABLE DEVELOPMENT OF THE NORTH AND THE ARCTIC ZONE OF RUSSIAN FEDERATION

Achieving “accelerated social and economic development” of the Russian North and the Arctic presupposes, among other things, the uninterrupted supply of hard-to-reach territories, to which there is no year-round access by land transport, with essential goods (food, medicine, fuel). At different periods of time, different delivery schemes were used to supply such territories - with a greater or lesser degree of state participation. Thus, during the Soviet period, northern deliveries were carried out entirely at the expense of the state. All experts note the high level of organization, the absence of failures, the wide range and volume of all necessary goods. With the country's transition to a market economy, the implementation of northern delivery activities was transferred to the level of the constituent entities of the Russian Federation. The decentralized model is characterized by disruptions in the supply of goods, their narrow range, low volume and inflated prices. Since 2024, a new special federal law on northern delivery has come into force, and by-laws are being actively developed and adopted to regulate the processes of delivering goods to hard-to-reach areas of the country. An analysis of the newly adopted regulatory documents indicates a return to centralized state management of northern deliveries. Conducting research on the role of public administration in the process of implementing northern delivery and its impact on the socio-economic development of the North and the Arctic is timely, which represents the relevance of the article. As a result of the study, conclusions were drawn that state regulation of northern imports today is the basis for the socio-economic development of the North and Arctic of Russia.

APPLICATION OF THE SAMUELSON EQUATION TO THE EVANS MODEL

Mathematical modeling of economic processes is an actual direction of research, because the well-being of citizens and the country as a whole depends on it. In the case of the market, the prices of most goods and services are not planned centrally, are not directly regulated by the state, but are freely set and changed by the market itself. The main factors that control the movement of prices in the market are the demand and supply of goods. In the economy, the most important are dynamic models, the parameters of which change over time. The Evans model (Walras-Evans-Samuelson model) is currently one of the basic concepts explaining the dynamic establishment of the equilibrium price in the market of one product under the influence of supply and demand. This is due to the fact that knowing the dynamics of the economic parameter we are interested in, we can try to build a forecast of its further evolution. The article examines the market of one product. For convenience, we will assume that the functions of the dependence of demand and supply on the price are given by linear relationships. The construction of the Evans model is that the change in price is directly proportional to the excess of demand over supply and the duration of this excess. The Samuelson differential equation with an initial condition, that is, the Cauchy problem, is obtained. Samuelson's equation has a stationary (equilibrium) point, which is a positive price at which supply and demand will be equal. The analysis of the obtained solution of the problem shows that over a long enough time (relatively speaking, at ) the price asymptotically approaches the equilibrium value. If we are not interested in the temporal dependence, but only in the equilibrium price, then it can be found from the differential equation immediately by setting the condition , this is the so-called limit stationary mode. The solution of the Cauchy problem is found by the method of variation of the constant. The parameterization of the model using the fractional differentiation operator in the sense of Gerasimov-Caputo is considered. The resulting solution was analyzed depending on the parameter . For this, the asymptotic representation of the function was used for large values of the argument. Conclusions are made regarding price dynamics in time relative to the equilibrium price when demand and supply are equal.

Impact of the COVID-19 Pandemic on Changes in Consumer Purchasing Behavior in the Food Market with a Focus on Meat and Meat Products-A Comprehensive Literature Review.

The coronavirus has wreaked havoc on the global economy before the eyes of the entire world. Due to evolving consumer needs and expectations during the pandemic, the supply and demand for various goods and services varied from the pre-COVID-19 period. This article aims to understand the changes in purchasing and food choices, focusing particularly on meat and meat products, made by consumers and households in response to the crisis caused by the COVID-19 pandemic. The study also indicates the impact directions of these changes and assesses the magnitude of the contribution of various determinants that influenced them. The literature review from 2020 to 2023 was conducted using Scopus and the Web of Science scientific databases. The study identified sociodemographic and individual factors as the main determinants influencing consumers' purchasing or eating behavior. Positive shifts (e.g., implementing strategies to better manage food at home through activities like creating shopping lists, the average increase in consumer spending during store visits, and decrease in visit frequencies) or negative changes (e.g., shortages of food products in stores due to consumer panic buying, unusually high demand resulting from stockpiling, purchasing fewer fresh products, increased consumption of unhealthy foods and snacking, among other factors) during isolation were influenced by various individual factors (e.g., motivation, mental state) or sociodemographic factors (e.g., gender, age, income level, education). While individual factors had a greater impact on changes in consumer behavior in the early stages of the COVID-19 pandemic, socio-demographic factors became more important as the pandemic progressed.

A paradox of coalition building in public good provision

Does partial coalition among players help mitigate the issue of underprovision of public goods? This study considers endogenous coalition formation and endogenous technology choices in a model of the private provision of global public goods. We show that the possibility of future interstate (partial) coordination may hinder the current adoption of better technology by a country outside the cooperation, which may exacerbate an existing underprovision problem. Specifically, in the subgame perfect equilibrium of a three-stage game, we find two paradoxical results: the inability to form future partial coalitions encourages a country outside the cooperation to adopt better technology, which could lead to an increase in the total public good supply and an improvement of global welfare. These results have important policy implications. For example, in the context of the Paris Agreement, if a major country announces reduced nationally determined contributions in a strategic move to adopt less advanced technology to motivate other countries to form coalitions, it may ultimately lead to a decrease in the overall supply of public goods and global welfare.

Free buccal fat pad graft for the bone defect filling of medication-related osteonecrosis of the jaws: A novel surgical approach

Surgical intervention for medication-related jaw osteonecrosis (MRONJ) is currently the main treatment method, offering a higher healing rate than conservative approaches. However, the management of bony defects after sequestrectomy remains a challenging issue due to poor vascularization from the drug effect. The use of pedicled buccal fat pad (PBFP) for filling bone defects has become common and effective but is limited to the posterior maxillary region. To add to the advantages of the buccal fat pad, we explored a novel treatment approach using a free buccal fat pad (FBFP) to fill bone defects other than the posterior maxilla. While the FBFP has been employed in oral defect reconstruction, currently published cases have been utilized in recipient sites with good blood supply. There has yet to be any usage in poor vascularization defects like MRONJ. This article describes that the FBFP was used to fill the surgical defects of 8 patients who were diagnosed with MRONJ and who underwent sequestrectomy and saucerization. During follow-up visits, there was excellent wound healing and no significant tissue depression. Based on successful treatment experiences, FBFP is a reliable therapeutic option for the management of poor vascularization defects like MRONJ treated through surgical intervention.

Impacts of climate hazards on households along the Drakensberg Mountains in the Free State Province of South Africa

Mountains are climate change hotspots and their ecosystems are key components in the supply of ecosystem goods and services to local communities. Low-income communities that directly depend on mountain resources are highly vulnerable to the harsh impacts of climate change. Using rainfall and temperature trends, and data collected from a household questionnaire survey, the objective of this study is to assess the impact of climate change on low-income households living in the Maluti-a-Phofung Municipality part of the Drakensberg Mountains. Climatic data were obtained from Climate Explorer while the household data were collected from a sample of 383 households in the villages of Qwaqwa. The results show that temperature and rainfall changes have significantly increased over a period of 120 years. About 51 percent of the respondents experienced extreme weather events which has the greatest impact on their households followed by drought (25.5%). Employment status was found to be significantly associated with the perception that hazards negatively impact natural resource availability, with 54% of those who had this perception being unemployed. In addition, income was found to have a significant relationship with extreme weather impacts on households and 60% of those households had a low monthly income of ZAR 2000 or less. Based on these findings, mountain households along the Drakensberg Mountains in Qwaqwa villages are already experiencing the negative impacts of climate change and their socio-economic characteristics indicate very low levels of adaptation capacity.

Implementasi Akad Murabahah di BNU’26 Magelang

This research focuses on implementing the Murabaha contract in BNU'26 Magelang District, the only community bank in Indonesia. BNU's problems in implementing the concept of pure Sharia are related to the constraints of banking laws prohibiting direct transactions. Therefore, to carry out Murabaha transactions, BNU has to partner with suppliers of goods. The second problem is more customer understanding of the Murabaha contract. This research was conducted at BNU'26 Magelang using a qualitative method. Data was collected through interviews. The results of this study indicate that murabaha financing uses murabaha bil wakalah, where the bank does not provide goods directly. Alternatively, the bank works with other parties to provide goods used as Murabaha financing to customers.

Exploring the Challenges of Industry 4.0 Adoption in the FMCG Sector: Implications for Resilient Supply Chain in Emerging Economy

Background: Fast-moving consumer goods (FMCG) supply chains are experiencing various challenges due to the interactions between consumers and decision-makers during physical distribution, manufacturing, wholesale and retail. One possible strategy to address these challenges for smoothing the supply chain (SC) and logistics operations is to adopt Industry 4.0 (I4.0) based technologies in the FMCG business processes. In this regard, digitalization and automation of the FMCG supply chain can be strengthened by the alluring properties of I4.0 technologies. Methods: This study identified nine significant challenges through a literature review and expert validation. Later, the challenges were evaluated using a novel multicriteria decision-making (MCDM) framework, the Bayesian best worst method (BWM). Results: The findings indicated that “requirement for substantial investment and resources”, “incompatible technological infrastructure” and “poorly structured value chain” are the most significant challenges to implementing I4.0 in the FMCG industry. Conclusions: The study is expected to significantly contribute to improving the FMCG supply chain’s resilience, sustainability, visibility, traceability and responsiveness. Additionally, the research can provide industrial practitioners valuable insights into implementing I4.0 in FMCG and similar sectors and thus promote SC sustainability and resilience in those industries.

Navigating the VAT Landscape: Unwrapping the Complexities of Gifts in Deco Proteste – Editores

In the case of Deco Proteste – Editores, the ECJ has ruled that a low-value gift, such as an inexpensive tablet or smartphone, provided with a magazine subscription, should be considered part of a single supply. In this context, the magazine subscription is deemed to be the main service, while the gift of the device becomes ancillary to that delivery. In this article, the author analyses this judgment, which in his opinion narrows the application of deemed supplies of goods in the context of promotional activities with gifts.

Понятие товара в законодательстве об организованных торгах

Considering the tasks set by the government for the economy, the legal mechanisms for entering into contracts for the sale (supply) of goods on exchanges will continue evolving and improving, and the list of items that can be traded on exchanges will expand further. In order to create representative indicators and fair market prices for goods that are significant for the country (which cannot always be considered things), it seems reasonable to apply the concept of “goods” in a broader sense, including therein other objects of civil rights, other property, in addition to things, or even name specific property rights depending on which objects of civil rights the new “incorporeal” entities discussed above will be classified as in the Exchange Trading Law. An interesting question is that of listing on exchanges goods that are not things, but, as stated above, can also be traded on exchanges (carbon units, “green” certificates, and other similar objects). Considering the qualitative characteristics of such exchange-traded objects, one cannot speak of quality in the same sense as with things, nevertheless, the characteristics that objects may have in order to become exchange-traded commodities must be determined by the exchange establishing admission rules.

ПРИКЛАДНЫЕ ЦИФРОВЫЕ ПЛАТФОРМЫ И ИХ ПРИМЕНЕНИЕ В ЛОГИСТИКЕ

The development of digital technologies will radically change all spheres of human activity (public administration, citizen participation, public policy, infrastructure development, new business areas, smart technologies and online platforms, new decision support systems, digital educational technologies, etc.). In the digital age, transportation systems and the supply of goods are becoming increasingly important for the mass adoption of smart and connected digital technologies and applications. This revolution is needed to create supply chain benefits in a world where disruption and shortages will continue. In this vein, it is especially important to correctly understand how to use digital technologies for the highest good.

Social learning to promote forest restoration in a semi-arid landscape in North Africa

Forest restoration is a suitable tool to mitigate land degradation and enhance the supply of vital goods and services. Social participation in forest restoration has gained increasing interest. Yet, the impact of participation on people's perception of ecological restoration and the restoration process has barely been addressed despite its relevance for the long-term success of restoration actions. We assessed mutual learning of different stakeholder groups in a ten-year demonstration project, and its potential to foster continued participatory forest restoration in Beni Boufrah valley, a semiarid area located in North Morocco. We performed face-to-face interviews to assess post-restoration individual learning for a subset of 15 highly engaged stakeholders using five components of social learning: reciprocal determinism, self-reflective capability, expectations, self-regulation and locus of control. Furthermore, we organized a workshop to assess collective learning in the study area. The lessons learnt by the project team was described using monitoring vegetation measurements, field visits and meetings, and stakeholder recommendations. Two thirds of the stakeholders showed an increasing awareness of the reciprocal relationship between people and the environment, while recognizing the inappropriateness of current behaviors and practices. Farmers showed continuous mistrust towards the Forestry Agency which justifies the need for more innovative approaches to resolve persistent conflicts, integrate forest and agricultural interventions and establish new mechanisms for economic motivation. Stakeholders acquired theoretical and practical concepts on forest restoration, but self-initiated activities were scarce and reinforcement of environmental awareness is still needed. There was a high impact of drought on seedling survival and growth along with a decrease in stakeholder engagement over the years. We could identify and implement a series of practical corrective measures, namely participatory re-planting, plot fencing, establishment of a local monitoring committee, and raising awareness activities. Such participatory implementation of corrective measures may enhance the credibility of the restoration process and it can be further tested in similar semiarid areas of North Africa even at a larger scale.

Last Time Buys during Product Rollovers: Manufacturer &amp; Supplier Equilibria

Durable goods customers expect long-term availability of spare parts to maintain their product. This puts a strain on supply chains. Part suppliers want to obsolete older generations of parts with declining demand and reassign resources to new, growing generations. Meanwhile, durable goods manufacturers that purchase and sell spare parts to customers want suppliers to keep producing old parts. When suppliers offer a “last time buy” opportunity for legacy parts in anticipation of their retirement, manufacturers push back. We study the strategic interaction and equilibria of a supplier and a manufacturer during the rollover between a legacy part and its successor in a durable good supply chain. Evidence from our interviews shows that manufacturers attempt to use the future business of the new part to delay a supplier’s last time buy of the old part. However, this tactic is often ineffective in practice. We propose a two-stage noncooperative game that reproduces the behaviors observed in interviews. Our analysis of this game distills the conditions under which a manufacturer can leverage the future business to delay a last time buy. There exist only six strategies that achieve this delay. We present a necessary and sufficient condition for these six strategies to be subgame perfect Nash equilibria. The condition reduces to a closed-form threshold on the new part volume. We conclude with practical insights that can guide managers during a rollover discussion.

Aligning agri-environmental-climate public good supply and desire in a sustainable Dutch agricultural sector.

European agricultural policies increasingly incorporate mechanisms for delivery of public goods. Sustainable public good delivery requires alignment between societal demand and landscape supply. However, the variation of demands or desires regarding future public good delivery among society is hardly known. We inventoried the desires for public goods across Dutch society, and projections of agricultural supply. A multi-method approach was used to find agreement levels between desired and expected change in good delivery. Most stakeholders expressed a desire for biodiversity and climate regulation from agriculture, whilst desire for natural heritage and recreation was less common. The utility of a public good to a stakeholder appears to influence its desire. Scenarios for agriculture focus on extensification, sustainable intensification, regionalization, or meadow bird conservation. Regionalized scenarios showed the highest agreement between public good supply and desire. Maximizing alignment between desire and supply thus requires a challenging transition towards region-specific agricultural sustainability strategies.

A modified pull-through approach with a pedicled bone flap for oral and oropharyngeal cancer resection: a feasibility study

PurposeCompromised swallowing, speaking, and local complications are the major disadvantages of established approaches to the posterior tongue and oropharynx. The mandibular split involves an esthetically unpleasant bipartition of the lower lip and is prone to bony non-union or sequestration. The conventional pull-through technique on the other hand lacks the secure reattachment of the lingually released soft tissues.MethodsThe feasibility of a new modified pull-through approach was tested on three anatomical specimens. CAD/CAM cutting guides were used to design a retentive bone flap to properly refixate the genioglossus and geniohyoid muscles after the procedure. The radiographic assessment and treatment planning was performed on 12 cadavers. The entire procedure was tested surgically via dissection in three of those cases. This procedure was then applied in a clinical case.ResultsPrecise repositioning and dynamic compression of bony segments was possible reproducibly and without injury to adjacent structures. In all dissected cases, a median lingual foramen was found and in two cases vessels entering it could be dissected Radiologic anatomical landmarks were sufficient in all 12 cases to perform the clinical planning procedure. Clinically, the osteotomized segment demonstrated good blood supply and plateless repositioning was verified postoperatively via cone beam scan.ConclusionThe method presented is safe and easy to perform. Individual cutting guides improve the safety and accuracy of the procedure, potentially eliminating the need for osteosynthesis. We provide the anatomical and radiologic basis for clinical evaluation of this pedicled bone flap procedure and present the clinical application of this modified pull-through approach.

A Systematic Review of Strategic Supply Chain Challenges and Teaching Strategies

Background: This study provides a comprehensive overview of current supply chain challenges and how they are taught within university circles or among supply chain professionals to simulate reality. Methods: The study applied a systematic literature review, using bibliometric co-citation and concept-centered content analysis for a comprehensive review of 118 relevant articles, leading to the identification of critical challenges in modern supply chain management. Results: These challenges include supplier selection and quality, supply chain networks, and sustainable supply chains. Supply chain educators are encouraged to use games that mirror real-world scenarios to teach these challenges. Results from this review underscore that existing games covered supply chain concepts such as the bullwhip effect, collaboration, networks, supplier selection, quality management, humanitarian logistics, sustainability, lean supply chain, Supply Chain 4.0, and perishable goods supply. Conclusions: The study’s contribution is to assist in selecting games tailored to the supply chain specific aspects and to guide developers in creating realistic games that address recent challenges in supply chain management. It recommends a holistic approach to enhance new supply chain game development, drawing from methodologies such as problem-based learning and Lego Serious Play. This multifaceted approach imparts practical knowledge and comprehensive skills for addressing supply chain intricacies in modern business settings.
