Bi-algebraicity in the rank one Riemann-Hilbert correspondence via o-minimality

For a smooth, projective, complex algebraic variety X, the Riemann–Hilbert correspondence establishes a complex analytic isomorphism between the ‘Betti moduli space’ of rank n local systems on Xan and the ‘de Rham moduli space’ of rank n vector bundles with flat connection on X. In the rank one case, C. Simpson precisely characterizes the subvarieties of these moduli spaces that are ‘bi-algebraic’ for this typically transcendental, analytic isomorphism. In this short note, we give a new proof of this characterization of Simpson, using methods from o-minimal geometry. We adapt the o-minimal proof to a p-adic setting, namely that of Mumford curves.

N-acetylcysteine microparticles reduce cisplatin-induced RSC96 Schwann cell toxicity.

Cisplatin is known to cause inner ear dysfunction. There is growing evidence that cisplatin-induced demyelination of spiral or Scarpa's ganglion neurons may play an additional role in drug-induced ototoxicity alongside afferent neuron injury. As Schwann cells produce myelin, there may be an opportunity to reduce ototoxic inner ear damage by promoting Schwann cell viability. This work describes a cellular model of cisplatin-induced Schwann cell injury and investigates the ability of the antioxidant N-acetylcysteine to promote Schwann cell viability. A local delivery system of drug-eluting microparticles was then fabricated, characterized, and investigated for bioactivity. RSC96 rat Schwann cells were dosed with varying concentrations of cisplatin to obtain a dose curve and identify the lethal concentration of 50% of the cells (LC50). In subsequent experiments, RSC96 cells were co-treated with cisplatin and both resuspended or eluted N-acetylcysteine. Cell viability was assessed with the CCK8 assay. The LC50 dose of cisplatin was determined to be 3.76 μM (p = 2.2 x 10-16). When co-dosed with cisplatin and a therapeutic concentration of resuspended or eluted N-acetylcysteine, Schwann cells had an increased viability compared to cells dosed with cisplatin alone. RSC96 Schwann cell injury following cisplatin insult is characterized in this in vitro model. Cisplatin caused injury at physiologic concentrations and N-acetylcysteine improved cell viability and mitigated this injury. N-acetylcysteine was packaged into microparticles and eluted N-acetylcysteine retained its ability to increase cell viability, thus demonstrating promise as a therapeutic to offset cisplatin-induced ototoxicity.

Sustainable gains from inland waterway investments at port-city interface

The objective of this research is to identify and quantify the sustainable impacts resulting from transportation investments at the port-city interface. These investments encompass two main components: 1) restoring the local inland waterway fairway for navigation, and 2) constructing a new railway bridge that traverses the primary waterway at the entrance of the seaport. The study is centered on the local transportation system in the northwestern region of Poland. Sustainability is assessed using an analytical tool derived from societal cost-benefit analysis and simulation in the relevant market transport performance in options with and without investment. Economic effects are evaluated in terms of savings in generalized transportation costs, which include transport operating expenses and travel durations. Environmental considerations encompass transport-related air pollution, greenhouse gas emissions, and well-to-tank emissions. Social aspects focus on issues like transport congestion, traffic noise, and transport-related accidents. Each type of investment yields distinct sustainable gains and distributes them among stakeholders differently. Additionally, the enhanced capacity of the rail bridge reveals the potential for a modal shift in the local passenger transport system, wherein passengers may transition from buses/cars to a fast railway. Tangible gains expressed in monetary terms allow for a sustainable assessment of transport investments. The elaborated research scheme can be employed to assess the sustainable ramifications arising from investments in intermodal transport at any port-city interface. It provides decision-makers with comprehensive insights into the economic, environmental, and social implications of various transport policies and interventions.

FFD-SLAM: A Real-Time Visual SLAM Toward Dynamic Scenes with Semantic and Optical Flow Information

To solve the problem of poor localization accuracy and robustness of visual simultaneous localization and mapping (SLAM) systems in highly dynamic environments, this paper proposes a dynamic visual SLAM algorithm called FFD-SLAM that fuses the target detection network with the optical flow method. The algorithm considers ORB-SLAM2 as the basic framework, joins the semantic thread in parallel with its tracking thread, initially obtains the set of feature points through the real-time detection of dynamic objects in the environment through YOLOv5 in the semantic thread, then filters the set of feature points obtained in the semantic thread through the optical flow module, and finally utilizes the remaining static feature points for the matching calculation. Experiments showed that the proposed algorithm showed an improvement of approximately 97% in the localization accuracy compared with the ORB-SLAM2 algorithm in a highly dynamic environment, which effectively improves the localization accuracy and robustness of the system. The proposed algorithm also showed a higher real-time performance compared with some excellent dynamic SLAM algorithms.

Neuromorphic place cells

A neuromorphic simultaneous localization and mapping (SLAM) system shows potential for more efficient implementation than its traditional counterpart. At the mean time a neuromorphic model of spatial encoding neurons in silicon could provide insights on the functionality and dynamic between each group of cells. Especially when realistic factors including variations and imperfections on the neural movement encoding are presented to challenge the existing hypothetical models for localization. We demonstrate a mixed-mode implementation for spatial encoding neurons including theta cells, egocentric place cells, and the typical allocentric place cells. Together, they form a biologically plausible network that could reproduce the localization functionality of place cells observed in rodents. The system consists of a theta chip with 128 theta cell units and an FPGA implementing 4 networks for egocentric place cells formation that provides the capability for tracking on a 11 by 11 place cell grid. Experimental results validate the robustness of our model when suffering from as much as 18% deviation, induced by parameter variations in analog circuits, from the mathematical model of theta cells. We provide a model for implementing dynamic neuromorphic SLAM systems for dynamic-scale mapping of cluttered environments, even when subject to significant errors in sensory measurements and real-time analog computation. We also suggest a robust approach for the network topology of spatial cells that can mitigate neural non-uniformity and provides a hypothesis for the function of grid cells and the existence of egocentric place cells.

Farming with a mission: the case of nonprofit farms

AbstractOrganizations interested in food alterity, security, and justice are often governed as 501(c)(3) nonprofits. As such, they are required to fulfill missions beyond profit maximization. This study focuses on the role of nonprofits in the agrifood system. Looking at nonprofit farms as both farms and as nonprofits, we seek to understand whether nonprofit organizations, as an alternative mode of governance, creates the possibility of an alternative economic practice, set apart from the conventional food system. We constructed a national database of nonprofit farms and the characteristics of the counties in which they are located. Our findings indicate that nonprofit farms tend not to be in the places with the most need of the services provided, which we argue is due to the structure of nonprofit governance, namely that nonprofits, while not profit-maximizing, are dependent on external resources, particularly donations. While they do operate as an alternative economic practice, their nonprofit mode of governance renders them unable to repair the failures of the current food system. Nevertheless, these farms do contribute to their local communities, both in terms of meeting their mission and as members of a broader local food system infrastructure. This is true whether or not these farms specifically state that food system transformation is part of their mission.

ФІНАНСОВА СТІЙКІСТЬ ТЕРИТОРІАЛЬНИХ ГРОМАД У ВОЄННИЙ ЧАС: РОЛЬ ПОДАТКОВИХ ДОХОДІВ

Introduction. External aggression has become the backdrop against which the resilience of the local self-government system has manifested as an element of crisis management within the vertical system of public administration. The war has exacerbated territorial disparities and differentiated the challenges for local self-government bodies in various regions due to their distance from combat zones and occupation, leading to the emergence of new functions not typical for local self-government bodies. Problem Statement. These circumstances have precipitated a change in the conditions for the formation of tax revenues for the budgets of territorial communities. Firstly, there has been a transformation in the state's approach to budgetary and tax policy formation, reflected in amendments to budgetary and tax legislation. Secondly, hostilities have resulted in a shift in the spatial concentration of businesses and increased unevenness in population density as a consequence of forced displacement to safe areas. These factors have influenced the process of budgetary revenue accumulation at the local level and, consequently, the financial resilience of territorial communities and their capacity to fulfill their functions. Purpose. To analyze the accumulation of tax revenues for the budgets of territorial communities as a factor in ensuring/preserving their financial resilience. Methods. General scientific and specialized methods were employed, including analysis, synthesis, grouping, description, comparison, theoretical generalization, and abstract-logical reasoning. Results. Based on five indicators (tax capacity of budgets, tax sufficiency, tax autonomy, local taxes and fees, taxes on economic activity), an analysis of the formation of tax revenues for the budgets of territorial communities in the context of maintaining their financial resilience during the war against Ukraine has been conducted. An increase in disparities in the tax capacity of territorial communities and an increase in the number of administrative-territorial formations in a crisis state have been identified. The impact of two factors on the resilience stability of communities in wartime has been established: distance from combat zones and available economic potential. It has been demonstrated that communities with a high level of economic potential are characterized by higher financial resilience even in conditions of close proximity to the front line, as well as the significant role of large cities in maintaining financial and economic resilience in the region. Conclusions. It is argued that the system of tax revenue formation for territorial communities has become one of the main factors in preserving/ensuring financial resilience of territorial communities during wartime. The influence of high adaptability of economic actors in territorial communities on stabilizing the economy of communities in the second year of the war has been noted.

Research ethics preparedness during outbreaks and public health emergencies: Focus on community engagement

Research represents an essential component of the response to infectious disease outbreaks and to other public health emergencies, whether they are localised, of international concern, or global. Research conducted in such contexts also comes with particular ethics challenges, the awareness of which has significantly grown following the Ebola outbreak in West Africa, the Zika outbreak in Latin America and the COVID-19 pandemic. These challenges include the need for implementing meaningful community engagement with the researched communities, not just to build unidirectional trust towards the research team, but to achieve a genuine and mutually respectful partnership before, during and after the research. Here, we describe the real-life experience of 10 well-established research clinics in Nairobi, where a successful experience of community engagement linking prevention and care to research was interrupted during the COVID19 pandemic. We contrast this experience with the concept and processes of community engagement as described in selected scientific manuscripts and guidelines, to formulate some conclusions and recommendations. We contend that more action is needed, from research ethics committees and other key-research stakeholders, to align policies and practices with ethics guidance and with evidence-based recommendations from the academic literature, to achieve meaningful community engagement during emergency research, irrespective of the scale and location of an outbreak or public health crisis. Failure to do so, will aggravate the (postcolonial) asymmetries of power in global health and local systems.

Key issues in Japan's public health centers to prepare for future pandemics: a text mining study using a topic model.

In Japan, over 450 public health centers played a central role in the operation of the local public health system in response to the COVID-19 pandemic. This study aimed to identify key issues for improving the system for public health centers for future pandemics. We conducted a cross-sectional study using an online questionnaire. The respondents were first line workers in public health centers or local governments during the pandemic. We solicited open-ended responses concerning improvements needed for future pandemics. Issues were identified from these descriptions using morphological analysis and a topic model with KHcoder3.0. The number of topics was estimated using Perplexity as a measure, and Latent Dirichlet Allocation for meaning identification. We received open-ended responses from 784 (48.6%) of the 1,612 survey respondents, which included 111 physicians, 330 nurses, and 172 administrative staff. Morphological analysis processed these descriptions into 36,632 words. The topic model summarized them into eight issues: 1) establishment of a crisis management system, 2) division of functions among public health centers, prefectures, and medical institutions, 3) clear role distribution in public health center staff, 4) training of specialists, 5) information sharing system (information about infectious diseases and government policies), 6) response to excessive workload (support from other local governments, cooperation within public health centers, and outsourcing), 7) streamlining operations, and 8) balance with regular duties. This study identified key issues that need to be addressed to prepare Japan's public health centers for future pandemics. These findings are vital for discussions aimed at strengthening the public health system based on experiences from the COVID-19 pandemic.

Profiling the acceleration and deceleration components in elite futsal players

ABSTRACT This retrospective observational study explores the acceleration and deceleration demands of elite male futsal players (age: 28.8 ± 2.4 years, weight: 73.7 ± 6.2 kg, height: 175.9 ± 5.9 cm) in official matches. Utilising a local positioning system, tracking data from twelve matches involving two elite teams with nineteen players was analysed. Physical demands were assessed at various thresholds, considering standing and rolling efforts based on initial and final velocities. The most prevalent efforts were rolling accelerations (32.4%) and decelerations (31.3%), along with standing accelerations (18.7%) and decelerations (17.6%). A majority of efforts occurred within small distances (less than 10 metres), representing 27.9% to 71.1% of cases. Intensity comparisons revealed that larger distances consistently had significantly higher velocities (d = 0.67 to d = 5.91). High-intensity efforts over large distances were notably shorter than their low-intensity counterparts, both in standing (d = 1.75 to d = 1.98) and rolling (d = 0.64 to d = 0.82) effort types. In essence, elite futsal players predominantly engage in rolling accelerations and decelerations within short distances, exhibiting average speeds below 3 m·s−2. This insight into the nuanced dynamics of player movements provides valuable information for optimising training regimens and enhancing performance in elite futsal competitions.

Finding reconnection lines and flux rope axes via local coordinates in global ion-kinetic magnetospheric simulations

Abstract. Magnetic reconnection is a crucially important process for energy conversion in plasma physics, with the substorm cycle of Earth's magnetosphere and solar flares being prime examples. While 2D models have been widely applied to study reconnection, investigating reconnection in 3D is still, in many aspects, an open problem. Finding sites of magnetic reconnection in a 3D setting is not a trivial task, with several approaches, from topological skeletons to Lorentz transformations, having been proposed to tackle the issue. This work presents a complementary method for quasi-2D structures in 3D settings by noting that the magnetic field structures near reconnection lines exhibit 2D features that can be identified in a suitably chosen local coordinate system. We present applications of this method to a hybrid-Vlasov Vlasiator simulation of Earth's magnetosphere, showing the complex magnetic topologies created by reconnection for simulations dominated by quasi-2D reconnection. We also quantify the dimensionalities of magnetic field structures in the simulation to justify the use of such coordinate systems.

Clinical Practice Guidelines to Support Capacity Building in Orthopaedic Surgical Outreach: An International Consensus Building Approach.

Surgical outreach to low- and middle-income countries (LMICs) by organizations from high- income countries is on the rise to help address the growing burden of conditions warranting surgery. However, concerns remain about the impact and sustainability of such outreach. Leading organizations (e.g., the World Health Organization) advocate for a capacity-building approach to ensure the safety, quality, and sustainability of the local health-care system. Despite this, to our knowledge, no guidelines exist to inform such efforts. We aimed to develop clinical practice guidelines (CPGs) to support capacity-building in orthopaedic surgical outreach utilizing a multistakeholder and international voting panel. We followed a modified American Academy of Orthopaedic Surgeons (AAOS) CPG development process. We systematically reviewed the existing literature across 7 predefined capacity-building domains (partnership, professional development, governance, community impact, finance, coordination, and culture). A writing panel composed of 6 orthopaedic surgeons with extensive experience in surgical outreach reviewed the existing literature and developed a consensus-based CPG for each domain. We created an international voting panel of orthopaedic surgeons and administrators who have leadership roles in outreach organizations or hospitals with which outreach organizations partner. Members individually reviewed the CPGs and voted to approve or disapprove each guideline. A CPG was considered approved if >80% of panel members voted to approve it. An international voting panel of 14 surgeons and administrators from 6 countries approved all 7 of the CPGs. Each CPG provides recommendations for capacity-building in a specific domain. For example, in the domain of partnership, the CPG recommends the development of a documented plan for ongoing, bidirectional partnership between the outreach organization and the local team. In the domain of professional development, the CPG recommends the development of a needs-based curriculum focused on both surgical and nonsurgical patient care utilizing didactic and hands-on techniques. As orthopaedic surgical outreach grows, best-practice CPGs to inform capacity-building initiatives can help to ensure that resources and efforts are optimized to support the sustainability of care delivery at local sites. These guidelines can be reviewed and updated in the future as evidence that supports capacity-building in LMICs evolves.The global burden of disease warranting surgery is substantial, and morbidity and mortality from otherwise treatable conditions remain disproportionately high in low- and middle-income countries (LMICs)1,2. It is estimated that up to 2 million (about 40%) of injury-related deaths in LMICs could be avoided annually if mortality rates were reduced to the level of those in high-income countries (HICs)3. Despite this, progress toward improved access to safe, timely surgery in resource-poor areas has been slow. Historically, nongovernmental organizations (NGOs) have tried to address unmet surgical needs through short-term outreach trips; however, growing criticism has highlighted the limitations of short-term trips, including limited follow-up, an increased burden on the local workforce, and further depletion of local resources4-6. In light of ongoing concerns, public health priorities have shifted toward models that emphasize long-term capacity-building rather than short-term care delivery. Capacity-building is an approach to health-care development that builds independence through infrastructure development, sustainability, and enhanced problem-solving while taking context into account7,8.

Calcipotriol Nanosuspension-Loaded Trilayer Dissolving Microneedle Patches for the Treatment of Psoriasis: In Vitro Delivery and In Vivo Antipsoriatic Activity Studies.

Psoriasis, affecting 2-3% of the global population, is a chronic inflammatory skin condition without a definitive cure. Current treatments focus on managing symptoms. Recognizing the need for innovative drug delivery methods to enhance patient adherence, this study explores a new approach using calcipotriol monohydrate (CPM), a primary topical treatment for psoriasis. Despite its effectiveness, CPM's therapeutic potential is often limited by factors like the greasiness of topical applications, poor skin permeability, low skin retention, and lack of controlled delivery. To overcome these challenges, the study introduces CPM in the form of nanosuspensions (NSs), characterized by an average particle size of 211 ± 2 nm. These CPM NSs are then incorporated into a trilayer dissolving microneedle patch (MAP) made from poly(vinylpyrrolidone) and w poly(vinyl alcohol) as needle arrays and prefrom 3D printed polylactic acid backing layer. This MAP features rapidly dissolving tips and exhibits good mechanical properties and insertion capability with delivery efficiency compared to the conventional Daivonex ointment. The effectiveness of this novel MAP was tested on Sprague-Dawley rats with imiquimod-induced psoriasis, demonstrating efficacy comparable to the marketed ointment. This innovative trilayer dissolving MAP represents a promising new local delivery system for calcipotriol, potentially revolutionizing psoriasis treatment by enhancing drug delivery and patient compliance.

Pediatric anesthesia outreach in low and middle-income countries: Models, motives, and moral misalignments.

A lack of anesthesia and surgical capacity leaves approximately 1.7 billion children per annum without access to surgical and anesthetic care. Over the past 50 years, the predominant strategy to address this lack of access has been to provide surgical capacity primarily from high-income countries (HICs) to low and middle-income countries (LMICs) in the form of short-term surgical missions. More recently, the international medical community has recognized the need to build sustainable surgical capacity in resource-constrained settings. This article reviews three models of surgical aid: the vertical model (short-term surgical missions); the horizontal model (system-wide capacity building); and the diagonal model, which is a hybrid of the first two. At their core, medical aid interventions exist on a spectrum ranging from providing surgical capacity to building surgical capacity. The skills, attitudes, and behaviors that drive success in providing medical capacity are fundamentally different from those that drive success in building medical capacity. The root cause of this difference is a shift in the moral duty of the visiting physician from a duty solely to the patient in front of them (based on the primacy of the doctor-patient relationship) to include a duty to the local physicians and the local medical system, and by extension to the next 10 000 patients in need of care. Failure to address the conflicts engendered by this fundamental moral shift risks undermining capacity-building efforts in all models of medical aid.

Calibration and pose measurement of a combined vision sensor system for industrial robot grasping of brackets

Recently, visual sensing measurement and its application in industrial robot operations have been widely researched, promoting the development of instrumentation and automation. This study proposes a combined vision sensor system for robot grasping, focusing on combined sensor system calibration and bracket pose measurements. The system configuration and working strategy of the combined vision system are introduced. Thereafter, the calibration of the combined vision coordinate systems is presented, wherein a global vision system acts as the external measuring equipment for accurately calibrating the local vision. Furthermore, a pose estimation method using a local vision system (LVS) is proposed, including morphology-based image enhancement and principal component analysis based corner recognition methods. Verification experiments, including combined calibration and bracket pose measurements, were performed to validate the effectiveness and accuracy of the proposed combined vision measurement strategy. The results demonstrated that the proposed system applies to industrial robot grasping of brackets. In addition, the proposed robot-sensor calibration method improves calibration accuracy. Finally, the proposed corner detection method is effective and accurate for different bracket detection applications. This study provides a system that improves robot grasping results by considering key factors, such as vision measurement accuracy, and calibration methods.

Towards a shared understanding of the learning health system in a large academic-based health system: A qualitative analysis.

Healthcare delivery is currently undergoing major structural reform, and the Learning Health System (LHS) has been proposed as an aspirational model to guide healthcare transformation. As efforts to build LHS take considerable investment from health systems, it is critical to understand their leaders' perspectives on the rationale for pursuing an LHS and the potential benefits for doing so. This paper describes the qualitative analysis of semi-structured interviews (n = 17) with health system leaders about their general perceptions of the LHS, description of key attributes and potential benefits, and perception of barriers to and facilitators for advancing the model. Participants universally endorsed the goal of the local health system aspiring to become an LHS. Participants identified many recognized attributes of LHS, though they emphasized unique attributes and potential benefits. There was also heterogeneity in participants' views on what to prioritize, how to structure the local LHS within existing initiatives, and how new initiatives should be implemented. Improving conceptual clarity of attributes of the LHS would improve its potential in guiding future reform.

Experimental study on the punching failure model of soft red rock subgrade by BPT-BVM methods and it’s assessment of the load bearing capacity

The recommended bearing capacity of medium weathering mudstone foundation is less than the capacity of the rock structure to withstand loads in Southwest China. A comprehensive failure characterization of medium weathering mudstone in Chengdu has been performed including bearing plate test (BPT), binocular vision measurement (BVM) test, uniaxial compressive strength test, trial trench test of shallow rock surface and 3D imaging in this paper. Failure behavior of rock has been modeled with 3D imaging algorithm that utilizes Zhang’s calibration method in BVM system combination with trial trench test of shallow rock surface. The bearing capacity of medium weathering mudstone foundation were extracted from uniaxial experiments and BPT-BVM test by fitting relevant material properties to the data. The results revealed that: Bearing capacity of medium weathering mudstone of layered isotropic in Chengdu is undervalued. Specifically, the characteristic load carrying value is in the range 1500–2500 kP, that is 50% higher than in the local standard system. Failure process is different from Hoek–Brown Failure Criterion, presenting a wave peak transfer phenomenon of the increment displacement into the distance. Thus, it can be reduced to that of punching failures for thin bedded structures of Moudstone foundations. Compressive strength of soft rock proves to be main factor limiting the bearing capacity, a clear correlation between the uniaxial compressive strength reduction coefficient and the bearing capacity has been used to establish, leading to the proposal of a load bearing capacity prediction model.

An Aboriginal-led, systemic solution to Aboriginal baby removals in Australia: Development of the Bringing Up Aboriginal Babies at Home program

The increasing rate of statutory Aboriginal infant removal in Australia, which has reached almost 10% of live births in the state of Victoria, is a crisis motivating radical change in child protection pathways. This paper describes the problem analysis and design phases of an Aboriginal-led systems change project intended to ensure Aboriginal infants are raised safe and strong in family, Community, and culture by creating a response capable of shifting underlying system factors. Dialogue and deliberation processes involving 27 practitioners working within Aboriginal health and social care programs in the Bayside Peninsula Area of metropolitan Melbourne, the traditional land of the Bunurong people, was the overarching method used to develop a shared understanding of the problem of Aboriginal infant removals and reach a consensus about what to do in the local system. The themes that emerged during problem analysis reflect a risk/bias theoretical perspective, and in the design phase, it was deemed necessary to reduce both child safety-related risk as well as bias in the child protection system that responds to risk. The ensuing Bringing Up Aboriginal Babies at Home program has a clear systems theory of change, and a service blueprint describing how it is going to be implemented. Bringing Up Aboriginal Babies at Home practice resonates with other programs that have evolved independently in Australia and in other western child protection jurisdictions to reduce infant removals, including building trust for engagement, inspiring hope, openness and transparency, activating extended networks of formal and informal supports, and close collaboration with antenatal and child protection services. Program evaluation will determine whether Bringing Up Aboriginal Babies at Home (BUABAH) can be implemented with fidelity, tackle identified system flaws, reduce the number of Aboriginal infants taken into statutory care and become sustainable.

Building an inclusive ecosystem for minority and women entrepreneurs: A case study of Columbus

We all agree that it is essential to build an inclusive entrepreneurship ecosystem for all kinds of people, particularly minority and women entrepreneurs, as the past studies are clear to demonstrate underperformance of those demographic groups. At the same time, we are only beginning to understand what kind of systemic barriers exist for women or minority entrepreneurs at the regional system level. Furthermore, it requires a different set of knowledge about how we can practically create an inclusive ecosystem. This paper applies the concept of equity planning for the context of economic development. This paper examines a case study of the City of Columbus, Ohio, in 2018–2019 in which the City Government actively promoted to build an inclusive ecosystem for women and minority entrepreneurs. We induce five essential steps that we could learn from this inclusionary practice which provide tangible implications for other city governments, nonprofit organizations, foundations, and other stakeholders of local entrepreneurship systems.
