Dynamic of Land Use and Associated Ecosystem Service Value in the Chengdu–Chongqing Urban Agglomeration, China

Understanding the long-term land use changes in the Chengdu–Chongqing urban agglomeration, a vital element of the Yangtze River Economic Belt and a key economic growth center in western China, can offer scientific basis and policy direction for improving regional ecosystem service values (ESVs), environmental conservation, and sustainable development. This study investigated the features connected to land use change, changes in landscape patterns, and variations in ESV across this region by means of time series of remote sensing and socio-economic data from 1990 to 2020. Additionally, the correlations between landscape pattern indices and ESV were examined. The findings indicated that: (1) cultivated land and grassland in the Chengdu–Chongqing urban agglomeration exhibited a declining trend, while forest, water, and construction land demonstrated increasing trends; (2) human activities significantly affected the Chengdu–Chongqing urban agglomeration, resulting in severe landscape fragmentation, heterogeneity, complexity of types, and patch separation, although the predominant patch types maintained strong connectivity; (3) the ESV of the Chengdu–Chongqing urban agglomeration initially decreased, reaching a minimum of CNY 5.017 billion in 2000, and subsequently rose again. Forest land accounted for approximately 69% of the overall ESV in the region over the preceding decades. The policy of reverting farmland to forest, the establishment of wetland parks, and the increased awareness of environmental protection have led to notable alterations in land use types and landscape patterns within the Chengdu–Chongqing urban agglomeration, which can significantly improve the regional ecosystem service value; however, the extent of influence and trends among various landscape indices are disparate.

Exploring the interaction between Kendari’s economic growth and its hinterland

In order to attain high economic growth and equitable economic development, each region has to determine its regional economic growth centre. The existence of an economic growth center allows for the concentration of economic activity, which in turn has a ripple effect on the surrounding areas (Hinterland). This study was carried out to identify the primary centres of economic growth in Kendari and analyse their interactions and influence on the surrounding hinterland. This study employed both primary and secondary data, which were analysed using scalogram analysis, centrality index analysis, and gravity analysis. The findings indicate that among the eleven sub-districts in Kendari, three of them, namely Kadia, Kendari Barat, and Mandonga, serve as economic growth centres. Each economic growth centre is connected with a primary hinterland that exhibits the highest level of attraction or interaction value when compared to other districts. Among these centres, Kadia is the sub-district with the higher growth centre hierarchy and it has the highest interactions with Wua-wua. The interaction value between Kadia and Wua-wua is 139595130.7. Kendari Barat is the second growth centre in terms of its interactions with Mandonga, with an interaction value of 710383315.6. Mandonga is the third growth centre that has the highest level of interaction with Kendari Barat, with an interaction value of 710383315.6. The implication of the study is to formulate more targeted policies based on strong empirical evidence.

Analysis of regional growth center and hinterland in Bantul regency

Increasing regional economic efficiency can be done through accelerated regional growth. Growth acceleration is known to produce two groups of regions, namely the growth center and Hinterland (supporting areas). This study aims to analyze the sub-districts that become growth centers and determine the value of community interaction between regions in Bantul Regency through comparative data in 2020 and 2022. In this study, secondary data is obtained through BPS Bantul Regency, which includes data, government facilities, education facilities, health facilities, worship facilities, economic facilities, communication facilities, tourism facilities, population, and distance between sub-districts. The analysis method used in this research is scalogram and gravity analysis, which was processed using Microsoft Excel. The results of the scaling analysis show that in 2020, there are five regional growth centers in Bantul Regency, which include Kasihan Subdistrict, Sewon Subdistrict, Banguntapan Subdistrict, Jetis Subdistrict, and Bambanglipuro Subdistrict. Meanwhile, in 2022, the scaling analysis shows that there are five regional growth centers in Bantul Regency, which include Banguntapan Sub-district, Sewon Sub-district, Jetis Sub-district, Kasihan Sub-district, and Kretek Sub-district. Then, the results of the gravity analysis show that there are different interaction values. The research results show that local governments need to prioritize the development of sub-districts that are still Hinterland by the RPJMD of Bantul Regency.

ФОРМУВАННЯ МЕХАНІЗМІВ ПУБЛІЧНОГО ІНВЕСТУВАННЯ ПРОЄКТІВ РЕГІОНАЛЬНОГО РОЗВИТКУ: КОНЦЕПТУАЛЬНИЙ БАЗИС

Introduction. The development of mechanisms for public investment in regional development projects is an important task of modern economic policy in the context of globalization, decentralization, and the growing role of regions as centers of economic growth. The effectiveness of these mechanisms affects not only the progress of individual territories but also the sustainable development of the national economy as a whole. The necessary to study this topic is due, first, to the complexity of the process of forming public investment mechanisms: modern economic theory offers a wide range of approaches to solving this problem, but their adaptation to the realities of Ukraine requires additional research. Secondly, the insufficient use of the conceptual framework: the formation of new investment mechanisms should be based on scientifically sound concepts and take into account the best international practices. Third, the lack of an integrated approach: existing mechanisms are fragmented and do not always take into account the specifics of the regions, which reduces their effectiveness. Fourth, the low level of involvement of innovative financial instruments, such as public-private partnerships, development bonds, or grant funding. Fifth, the need to prepare policy recommendations: the results of the study will contribute to the development of effective tools to support regional development based on scientific analysis. Objective. The purpose of the article is to comprehensively study and build mechanisms for public investment in regional development projects. Methods. The methodological basis of the study is the theoretical provisions of economic and financial sciences, works of famous scientists. To solve the research tasks, the paper uses the dialectical method of scientific knowledge, methods of empirical and theoretical research, in particular, conceptual and logical analysis and a systematic approach. Results. Practical testing of the state policy, including at the regional and local levels, involves the use of both complex and purely functional mechanisms, tools, and means. The mechanism as the most systematic means of regulation is considered as a controlled set of elements (subjects, objects, purpose, goals, objectives, functions, principles, means, measures, tools for monitoring, control and adjustment, etc.) used to implement and solve public administration tasks in the relevant functional or other sphere of development of the state, its regions, territories. At the same time, the achievement of the general goal and policy objectives in such a complex area as public investment in regional development projects requires the use of a certain holistic system of mechanisms for such purposes, the basic of which are: institutional and legal, institutional and organizational, infrastructure, economic, social and psychological, monitoring and control. Conclusions. The formation and implementation of each of these mechanisms have their own clearly defined goals and objectives, which are generally subordinated to the general goal of the State policy in the analyzed area - the public investment institution's acting as a powerful factor in the development of communities, territories, and regions of the country.

Pengaruh Pengembangan Kawasan Ekonomi Khusus Pariwisata terhadap Pembangunan Wilayah

This study analyzes the influence of the development of Tourism Special Economic Zones (SEZs) on regional development, focusing on economic growth, poverty, and unemployment in the area around the SEZ. Using spatial econometrics methods, this study includes four SEZs: Tanjung Lesung, Mandalika, Morotai, and Tanjung Kelayang. The results show that Tourism SEZs have a positive impact on economic growth in certain regions, especially Tanjung Lesung, although their impact on the surrounding areas is still limited. Poverty and unemployment showed varied outcomes; some SEZs have decreased, but the influence has not been significantly evenly distributed. Domestic tourists play an important role in supporting economic growth, with variables of tourist attraction and accommodation capacity having a positive impact. However, the effectiveness of Tourism SEZs is still constrained by limited infrastructure and local community empowerment. The study emphasizes the importance of facility development and community involvement to optimize the benefits of SEZs as a new economic growth center.

Ranking as Method of Evaluating Old-Industrial Regions in Russia

Ranking is an acute method used in comparative estimation of regions in the system of state governance. The goal of ranking is to build typology and to carry out comparative analysis of old-industrial regions in order to assess the potential of their transformation into centers of economic growth in the Russian Federation. The article provides the review of authoritative Russian rankings of such regions that demonstrate topicality of using integral figures in the process of estimation. The author put forward methodology of old-industrial region ranking by dynamics of integral indicator in development and characterized its key stages and their content. The system of indicators was advanced to assess the potential of old-industrial region transformation into centers of national economy growth in Russia. This ranking methodology used regularly in the form of monitoring can give an opportunity to form the database concerning old-industrial regions and in proper time identify challenges and problems acute for a concrete region. On the basis of results of old-industrial region ranking we can draw a conclusion that regions of the first three groups of the ranking can be considered as potential centers of national economy growth as they possess the necessary potential of self-development, possibilities to participate in processes of regional interaction and stable institutions of development.

Determination of Service Centers Along the East Coast Corridor of Ogan Komering Ilir Regency

This study aims to determine service centers along the East Coast Corridor of Ogan Komering Ilir Regency using two analytical approaches: facility service index analysis and rank-size rule analysis. Perroux's growth center theory (1950) is applied to understand how districts with higher facilities and populations can stimulate surrounding economic growth. The facility service index analysis identifies the availability and distribution of public facilities in each district, while the rank-size rule maps population distribution to pinpoint potential service centers. The results show that Air Sugihan District holds potential as the primary service center due to its facilities, while Tulung Selapan District is designated as a settlement center given its largest population. With a balanced development strategy, it is expected that this can create equitable service access, foster economic growth, and strengthen the socioeconomic resilience of communities in Ogan Komering Ilir Regency.

Agropolitan Development Strategy Based Food Crops and Fisheries in Banjar Regency South Kalimatan Province

The agricultural and fisheries sector's role in increasing food supplies can also increase income through export activities. The development of metropolitan areas is expected to increase development based on agriculture and fisheries, where the contribution of the agricultural and fisheries sectors to GRDP is relatively small. The purpose of this study is to analyze the superior commodities of food crops and fisheries in the context of developing agropolitan areas, selecting agropolitan development areas through the availability of facilities and infrastructure in production center areas, and formulating agropolitan area development strategies. The research results show that rice and tilapia are superior commodities to be developed in agropolitan implementation in Banjar Regency. This can be seen from the LQ value obtained for rice and tilapia commodities which are greater than one, while corn and catfish have great potential to be developed and soybean commodities still do not have the potential to be developed or are not yet a basis where the value for these commodities is less than one. Banjar Regency has greater potential to be developed as a growth center or service center in the development of agropolitan areas in Banjar Regency because it has a more complete type and number of supporting facilities, and has competitive advantages to compete to become a new agropolitan area in South Kalimantan Province. The strategy for developing agropolitan areas in this research is to build agricultural and fisheries facilities and infrastructure (sub-terminal agribusiness) and strengthen capital institutions. Keywords: Agropolitan, Superior Commodities, Regional Development

Pemilihan Pusat Pertumbuhan Baru pada Daerah Mitra Ibu Kota Nusantara: Studi Kasus Kecamatan Penajam

The relocation of Indonesia’s Capital City of Nusantara (IKN) represents the government’s strategy to reduce regional disparities in the country. Penajam Subdistrict, which directly borders IKN area and serves as one of its partner areas, has significant potential as an economic driver, particularly for food security. Its geographical location gives it agricultural advantages, especially in the plantation subsector, which supports the national agricultural activities as directed by Presidential Regulation No. 63 of 2022. This potential may encourage the establishment of new growth centers that drive the economic sector through their leading plantation commodities. The development of these centers may also generate optimal polarization and downward trickling effects that benefit IKN partner areas. This study aims to identify new growth centers at a micro level in Penajam Subdistrict to support spatial utilization that aligns with IKN needs and sustainable regional development. Employing a quantitative method, this research utilizes centrality and accessibility index analysis as well as Location Quotient (LQ) techniques. The results of the study show that eight villages in Penajam have the potential to become new growth centers and serve as partner areas to IKN.

Pelayanan Pengaduan Masyarakat Peduli Lingkungan Pada Dinas Lingkungan Hidup Kota Palangka Raya

<em>Palangka Raya City, as the center of government and economic growth in Central Kalimantan, faces serious challenges in waste management. The increasing amount of waste generated by community and industrial activities demands attention and concrete action to maintain cleanliness and environmental sustainability. This community service activity aims to raise public awareness about the importance of proper waste management and to provide facilities for reporting and handling waste. The activities include socialization and counseling about the types of waste, the negative impacts of waste on health and the environment, as well as effective reporting procedures. By providing easily accessible reporting facilities, such as hotlines and mobile applications, it is hoped that the community can play an active role in reporting waste issues they encounter. The expected outcomes of this activity are increased public awareness, an increase in the number of waste reports, and more effective waste management, which in turn will contribute to a cleaner and healthier environment in Palangka Raya City. This community service activity is implemented as part of the Field Work Practice (PKL) of the Integrated School of Management Informatics & Computer (STMIK). This activity is expected to create a culture of shared responsibility in environmental management and support the sustainability efforts initiated by the local government.</em>

Guardians of the mind: Calvarial stem cells and brain border immunity

Calvarial bones safeguard the brain and are interconnected by immovable joints termed sutures, which function as growth centers for skull morphogenesis and stem cell niches. Recent years have witnessed paradigm shifts in this field, highlighting the essential roles of calvarial stem cells (CSCs), sutures, and surrounding structures in neuroimmune crosstalk and neurocognitive restoration.

Economic Development of the Major Cities in the Context of Demographic Challenges

In recent years, Russia has faced serious global challenges. Particular attention is required for demographic challenges, which are caused by natural population decline, ambiguous migration processes, and their exacerbation due to the spread of the coronavirus infection and subsequently the aggravation of the foreign policy situation. The largest Russian cities are centers of economic growth with significant potential for solving regional livelihood problems. An important indicator of the state and development of a city as a socio-economic system is the change in population size. The dynamics of demographic and other socio-economic indicators deserve detailed analysis and study. The results obtained must be considered when making strategic decisions and developing adaptation mechanisms. In the past five years, a natural population decline has prevailed in the studied largest municipalities, which is only partially offset by migration growth. In most cities with a population of over one million, there is a correlation between the dynamics of population growth (both natural and migration), the average wage level, and the quality of the urban environment. In cities with migration outflow, measures are needed to improve these parameters. Since all cities have developed industries, including due to natural and historical factors, systematic monitoring of the relevant indicators and a detailed analysis of the reasons for negative trends, including demographic ones, are important for ensuring balanced economic development. To ensure the balance of supply and demand in the labor market in terms of qualification and professional requirements and expectations, the implementation of regional programs and projects with the participation of government and business is proposed. In the context of the economic development of the largest cities and adaptation to global challenges, it is proposed that government authorities, local governments, the scientific community, and businesses identify new promising specializations for cities, including the need to enhance import substitution and implement high-tech, science-intensive industries.

Morphosedimentary evolution of the Belgica Mound Drift: Controls on contourite depositional system development in association with cold-water coral mounds

Small-scale contourite drift is an important component of continental margins that can record information about complex oceanographic processes. The Belgica Mound Drift is one example of a small-scale contourite drift. It is formed under the influence of cold-water coral (CWC) mounds and represents one of the most distal contouritic expressions influenced by the Mediterranean Outflow Water (MOW) in the NE Atlantic Ocean. Three distinct evolutionary stages have been identified from new high-resolution pseudo-3D reflection seismic data, each associated with a significant change in paleoceanography, affecting both bottom-current intensity and sediment input. The pre-drift stage (Pliocene–Early Pleistocene) corresponds to the regional RD1 erosive event, which was caused by the reintroduction of the MOW in the Porcupine Seabight, creating a distinct paleotopography that will influence all ensuing sedimentary processes. The second stage (Early Pleistocene–Middle Pleistocene) is the contourite drift inception in two distinct centres of growth, strongly steered by topographic obstacles such as the CWC mounds. During the third and final stage (Middle Pleistocene–present day), the contourite drift is developed under a more stable but less dynamic environment, characterised by more continuous and mounded aggradational stratification. The final stage of the contourite drift is related to the Middle Pleistocene Transition, with a spatially variable reduction in the MOW-related bottom currents and sediment input. The spatial and temporal evolution of this drift shows that its present-day morphology is controlled by the location of initial growth. Evolving moat morphology indicates that the intensity of the bottom currents generally increases during the drift evolution.This research presents a crucial paradigm for advancing our knowledge of elucidating the complexities of smaller-sized contourite systems in diverse oceanic environments.

Pola Spasial Pergeseran Pusat Pertumbuhan Desa di Kabupaten Kulon Progo

Kulon Progo is a poorest district and has the highest development inequality in Daerah Istimewa Yogyakarta (DIY) based on Badan Pusat Statistik (BPS) publication. The local government has made various efforts to overcome the problems, one of which is by establishing growth centers since 2003. However, Kulon Progo Regency has experienced rapid development with the existence of Yogyakarta International Airport, which affected the dynamics of regional growth centers. The purpose of this study is to identify the potential Rural Growth Center (PPD) and identify the spatial patterns of PPD shifts in Kulon Progo to see the trickle down effect. This study used descriptive quantitative methods using scalogram index, centrality index, urban network analysis, and gravity index, also moran’s I index and Local Indicator Of Spatial Association (LISA). The results showed that there was a shift in rural growth centers, but the spatial analysis did not show any trickle down effect from rural growth centers that had been formed before. However, new centers were formed that were not related to the previous rural growth centers. These results indicates that the rural growth centers in Kulon Progo cannot have a growth effect on the surrounding area.

Loss of MMP9 disturbs cranial suture fusion via suppressing cell proliferation, chondrogenesis and osteogenesis in mice

Cranial sutures function as growth centers for calvarial bones. Abnormal suture closure will cause permanent cranium deformities. MMP9 is a member of the gelatinases that degrades components of the extracellular matrix. MMP9 has been reported to regulate bone development and remodeling. However, the function of MMP9 in cranial suture development is still unknown. Here, we identified that the expression of Mmp9 was specifically elevated during fusion of posterior frontal (PF) suture compared with other patent sutures in mice. Interestingly, inhibition of MMP9 ex vivo or knockout of Mmp9 in mice (Mmp9-/-) disturbed the fusion of PF suture. Histological analysis showed that knockout of Mmp9 resulted in wider distance between osteogenic fronts, suppressed cell condensation and endocranial bone formation in PF suture. Proliferation, chondrogenesis and osteogenesis of suture cells were decreased in Mmp9-/- mice, leading to the PF suture defects. Moreover, transcriptome analysis of PF suture revealed upregulated ribosome biogenesis and downregulated IGF signaling associated with abnormal closure of PF suture in Mmp9-/- mice. Inhibition of the ribosome biogenesis partially rescued PF suture defects caused by Mmp9 knockout. Altogether, these results indicate that MMP9 is critical for the fusion of cranial sutures, thus suggesting MMP9 as a potential therapeutic target for cranial suture diseases.

Climate Change Impact and Adaptation of Traditional Fishermen in Rangas Village, Majene Regency

Abstract Most of the growth centers in Majene are developing in coastal areas which highly vulnerable to climate change impacts, with the economic sector most affected being capture fisheries. Rangas Village, Banggae District affected by climate change because 80% of the population in the area depends on the capture fisheries sector for their livelihood. Therefore, using qualitative descriptive method, this research aims to examine impact of climate change on traditional fishermen in Rangas Village and adaptation actions taken. Result of the research indicates that climate change impacts felt by fishermen is unpredictable weather, especially large sea waves which often become obstacles to their activities. To overcome this, they have to do fishing activity in area outside Majene Regency. Most fishermen still use traditional methods which is observation of wind movement to determine the right time to sail. Due to these adaptation measures, most fishermen did not experience a decrease in the number of catches. This is in accordance with statistical data which states that fish catches tend to increase from 2021-2023. However, there is a decrease in fish prices compared to previous years, which is due to fish stocks tending to exceed needs, so their income also tends to decrease.

Southeast Asia plays a major role in the global economy today. Industrial countries such as Malaysia, Singapore, Indonesia, the Philippines and Thailand make a special contribution to it. They represent one of the generally recognized "growth centers" of the open export-oriented model of the global economy. It is no coincidence, therefore, that today they are the focus of attention of politicians, economists and scientists from all over the world.

New insight into the thermal stability of the amorphous tetraphenyl-diamine (TPD) – A combined calorimetry/in-situ Raman microscopy study

Non-isothermal differential scanning calorimetry (DSC) was used to study the influences of particle size daver and heating rate q+ on the crystal growth and decomposition kinetics of amorphous N,N’-bis(3-methylphenyl)-N,N’-bis(phenyl)-benzidine (TPD). The macroscopic crystallization kinetics was found to be strongly dependent on q+. At high q+, the crystal growth proceeded dominantly from the mechanical defects acting as primary growth centers, with the corresponding activation energy being ∼70–80 kJ mol−1. At low q+, the crystalline phase was primarily formed from heterogeneous nuclei, with the activation energy for the growth process being ∼980 kJ mol−1. The prolonged nucleation led to extensive passivation of the surface mechanical defects with respect to their function as direct crystal-growth-accelerating centers. Temperature-resolved in-situ Raman microscopy has confirmed the conclusions derived from the DSC data and helped to identify the residual low-q+ defects-originating crystal growth as proceeding from volume-located micro-cracks. The X-ray diffraction analysis confirmed that TPD crystallizes into an identical phase under all circumstances. The thermal decomposition of TPD was found to proceed in a single step, by simple nth-order reaction kinetics with the activation energy of ∼120 kJ mol−1.
