The Growth of Cross‐Border Regions Toward “Two Countries, One Park”: A Case Study of the Mohan–Boten Cross‐Border Cooperation Zone

ABSTRACTCross‐border regions have been the frontier areas of regional and subregional cooperation, the development of which involves the interaction of multiple scales and various agents. Existing studies focus mainly on cross‐border economic cooperation but pay less attention to issues such as urban construction and community development, which may lead to the neglect of the interests of local communities in the development of cross‐border regions. Based on a case study of the Mohan–Boten Cross‐border Cooperation Zone (CCZ), this study argues for the integrated development toward “Two Countries, One Park” through the functional integration of urban planning, industrial investment, public services, and community development. The study finds that the success of the “Two Countries, One Park” pattern relies on the coordination of multi‐scalar governance and multi‐agent cooperation, whereas the “scale paradox” caused by the asymmetric distribution of power and responsibility among different governance scales and the relevant agents is a major hindrance to functional integration and cross‐border cooperation. Addressing the “scale paradox” is, therefore, crucial for successful cross‐border development.

The Frontier Areas’ Student Acceptance of Physics Fun-based Mobile Application: Incorporating the Process-Oriented Guided-Inquiry Learning (POGIL) Strategy

The acceptability of technology is an essential factor to consider, particularly in frontier areas that encounter challenges related to availability and limited educational resources. This study aims to evaluate the acceptance of physics learning tools in a virtual laboratory (V-Lab) platform, utilizing the POGIL strategy, referred to as the Physics Fun-based mobile application. Mobile learning refers to the learning process carried out through mobile devices such as smartphones. The implementation took place at a senior high school located in West Papua Province, one of Indonesia's frontier areas, with 136 students participating. The Technology Acceptance Model (TAM) and Theory of Reasoned Action (TRA) were employed in this quantitative study. Structural Equation Modeling (SEM) was implemented for data analysis. The findings indicated that Attitude (ATT) and Behavioral Intention (BI) were significantly influenced by Perceived Ease of Use (PEU) and Subjective Norm (SN), respectively, while Perceived Usefulness (PU) did not have a direct effect on ATT. As a result, to enhance the acceptance of technology, teachers and technology developers should prioritize enhancing ease of use and reinforcing social factors. This should be done with a particular emphasis on the social benefits and simple accessibility of technology in the learning process, particularly in frontier areas.

Evolution and simulation optimization of rural settlements in urban-rural integration areas from a multi-gradient perspective: A case study of the Lan-Bai urban agglomeration in China

With the rapid growth of global urbanization, rural land has been continuously occupied, which has brought about profound changes in human-land relationship. As a rural regional system in the frontier area of urbanization, the rural settlements in the urban-rural integration area (URIA) are in a profound transformation due to multiple disturbances such as internal natural factors and social and economic factors brought about by external urbanization. Based on the internal and external system factors of rural settlements, this paper constructs an analytical framework to explore the spatial and temporal evolution pattern of URIA rural settlements from 2000 to 2020, and then summarizes its evolution model, and predicts the situation of rural settlements in different scenarios in 2030. Finally, the optimal control strategy is proposed. The results show that: (1) From 2000 to 2020, affected by the gradient of natural environment, the scale of rural settlements in URIA shows a trend of decreasing in low-altitude areas near rivers and increasing in high-altitude areas far from rivers. Under the socio-economic gradient, there is a phenomenon that the scale of rural settlements in the inner edge of URIA with better socio-economic environment decreases and the scale of settlements in the outer area of URIA with poor socio-economic environment increases. (2) Based on different environmental factors, in the internal natural environment, it shows the evolution mode of “terrain containment” and “water source guidance”, while in the socio-economic environment, it shows the evolution mode of “urban sprawl encroaches rural”, “population decrease and land increase”. (3) The simulation results of rural settlements in 2030 show that the scale of rural settlements in the periphery of URIA continues to increase under the natural development (ND) scenario, while the scale of rural settlements in the inner edge decreases and the distribution is scattered. Under the urban-rural integration development (URD) scenario, rural settlements are mainly concentrated in the core area of URIA, and the area of rural settlements turning into urban land has dropped significantly. (4) Based on different gradients, the settlements are divided into three types: centralized development type, restricted development type and migration remediation type. Patch reconstruction is carried out by gravity model, which can theoretically save land and vacate 327 hm2 of construction land index. Compared with the extensive development model of the ND scenario, the URD scenario has important theoretical significance in limiting the blind expansion of the city and realizing the integration of urban and rural development in Lanbai.

The temporal and spatial changes in official facilities in Dali under the bureaucratization of native officers

ABSTRACT During the Ming and Qing dynasties, the bureaucratization of native officers led to a more systematic expansion of Chinese official facilities in frontier areas, resulting in large-scale changes in the local landscape. This expansion is a distinct chapter in the history of ancient urban construction. For the Dali region, where the central government took the lead during the Ming dynasty, this paper compares the construction history of defense, administration, rituals, and education in different periods and discusses changes of Chinese official facilities in the context of the bureaucratization of native officers. The results show the following: 1. The primary concern of the appointed officials was to establish cities and create safe and stable strongholds to demonstrate the authority of the center. 2. The official facilities of administration, sacrifice, and education are all around the official controlled road. In addition, they gradually extended to various areas to control Dali. 3. Through the building of administrative facilities to implement central control, sacrificial facilities to achieve ideological infiltration and educational facilities to implement basic education development, Dali gradually converged with the Central Plains. 4. The political strategy of the appointed officials toward Dali was as follows: build offices – schools -walls – temples.

Polymer-Gel-Derived PbS/C Composite Nanosheets and Their Photoelectronic Response Properties Studies in the NIR

Non-conjugated polymer-derived functional nanocomposites are one of the important ways to develop multifunctional hybrids. By increasing the degree of crosslinking, their photophysical properties can be improved. PbS is a class of narrow bandgap infrared active materials. To avoid aggregation and passivation of the surface defects of PbS nanomaterials, a large number of organic and inorganic ligands are usually used. In this study, PbS/C composite nanosheets were synthesized with Pb2+ ion-crosslinked sodium alginate gel by one-pot carbonization. The resulting nanosheets were coated on untreated A4 printing paper, and the electrodes were the graphite electrodes with 5B pencil drawings. The photocurrent signals of the products were measured using typical 650, 808, 980, and 1064 nm light sources. The results showed that the photocurrent switching signals were effectively extracted in the visible and near-infrared regions, which was attributed to the mutual passivation of defects during the in situ preparation of PbS and carbon nanomaterials. At the same time, the resulting nanocomposite exhibited electrical switching responses to the applied strain to a certain extent. The photophysical and defect passivation mechanisms were discussed based on the aggregation state of the carbon hybrid and the interfacial electron interaction. This material would have potential applications in broadband flexible photodetectors, tentacle sensors, or light harvesting interdisciplinary areas. This study provided a facile approach to prepare a low-cost hybrid with external stimulus response and multifunctionality. These results show that the interfacial charge transfer is the direct experimental evidence of interfacial interaction, and the regulation of interfacial interaction can improve the physical and chemical properties of nanocomposites, which can meet the interdisciplinary application. The interdisciplinary and application of more non-conjugated polymer systems in some frontier areas will be expanded upon.

Impact of Fan Position and Speed Adjustments in Glass Greenhouse Environments

In the context of the contemporary development of precision agriculture, glass greenhouses, as an important infrastructure for enhancing crop production efficiency and quality, have become a frontier area of agricultural science and technology innovation for the internal microenvironmental regulation, especially the optimization of airflow dynamics and temperature distribution. In this paper, the study is based on the three-dimensional turbulence model equations of Reynolds number and Darcy-Forkheimer law, and modeled the cases without and with crops, simulated their different wind velocity and temperature, generated the corresponding simulation diagrams and analyzed them, and the results show that changing the Wind velocity to 3m/s or changing the fan position to 1m is a better condition than that with Wind velocity of 2m/s and fan position of 1.3m. In this study, it was found that both variables, Wind velocity and fan position, could affect the growth of crops in glasshouse, excluding most of the factors.

ANALISIS PEMBIASAAN NILAI - NILAI AKHLAKUL KARIMAH SEBAGAI UPAYA PEMBANGUNAN KARAKTER PADA ANAK USIA DINI DI DAERAH TERDEPAN, TERLUAR DAN TERTINGGAL (3T) KABUPATEN ROTE NDAO

The phenomenon of a character crisis resulting in moral decline in the nation's generation should be overcome through the role of education as an effort to familiarize oneself with moral values. Schools and teachers have an important role in forming children's morals apart from family and parents in educating them, especially during the learning process. Facilitating the akhlakul karimah (noble character) needs of children in underdeveloped, outermost and frontier areas is an important and urgent challenge. This research uses a qualitative descriptive research approach. The aim of this research is to collect as much factual data as possible on the subject naturally in implementing the practice of akhlakul karimah values as an effort to build character in early childhood in frontier, outermost and disadvantaged areas (3T). Efforts to facilitate children's moral and moral needs are often not a top priority. Nevertheless, the importance of character and morality formation in children should not be ignored. To overcome this challenge, a collaborative approach between various parties, inclusive education that integrates moral values in educational programs, parent training, use of technology, community strengthening, and social skills development programs can be an effective solution.

Design of actuator motor acceleration model in dual axis tracker movement for stand-alone PV system

Stand-alone photovoltaic system or PV is a power generation technology with potential that is environmentally friendly and also one of the solutions for saving high electricity rates today. However, problems that often occur due to weather fluctuations that are always changing, especially North Sumatra, Indonesia result in the conversion produced by solar cells not being optimal. Therefore, it is necessary to do a new model with a dual tracker system and the development of accelerator motor actuators so that the resulting energy conversion is more optimal. The result of optimizing the reliability of the polycrystalline type solar panel which is designed with an additional photovoltaic tracker system to maximize the conversion of solar energy to solar panels is to obtain an output power of 303.72 volts DC and 267.52 volts DC in the position where the tracker is not used. Then the percentage increase in energy reached 29.80%. Dual axis tracker technology is able to maximize energy conversion in improving PV usage performance. The implementation of a stand-alone PV system will be beneficial if the installation is in Indonesian territory, especially in disadvantaged, frontier and outermost areas.

The power of modern 3-D visualization of high-resolution terrain models in geologic mapping: Complex fold geometries revealed by 3-D mapping in the Panamint metamorphic complex, eastern California, USA

We use structure from motion–multiview stereo (SM) terrain models developed from ground-based images and images acquired from uncrewed aircraft (aka drones) as a base map for three-dimensional (3-D) mapping on the walls of a deep canyon in the Panamint Range of eastern California, USA. The ability to manipulate the 3-D model with views from arbitrary look directions and broad scale range revealed structures that were invisible to conventional two-dimensional (2-D) mapping because of both the scale of the structures and their exposure on vertical to near-vertical cliff faces. The analysis supports field evidence for four phases of ductile deformation, with only one of the younger phases documented on early geologic maps of the area. The oldest deformational event (D1) produced the main metamorphic fabric and pre-dates Late Cretaceous plutons. This deformation produced a 200–250-m-thick high-strain zone localized along marbles at the top of the Kingston Peak Formation and lower Noonday Formation. Geometric analysis from the model suggests strongly that large sheath folds at scales of 100–300 m are developed within these marbles. Large measured finite strains indicate displacement across this apparent shear zone of at least 4–5 km and displacements of tens of kilometers are allowable, yet the structure is invisible to conventional mapping because the high-strain zone is stratabound. The main fabric shows two clear overprints and a third that is likely an even younger deformation. D2 and D3 generated tight to close, recumbent folds and open to tight, upright folds, respectively, both folding the main foliation with localized development of crenulation cleavages axial planar to the folds. An additional overprint shows no clear cross-cutting relationship with D2 or D3 fabrics and could be a manifestation of either of those events, although the deformation is spatially limited to a narrow shear zone beneath a brittle, dextral-normal fault with the same kinematics as a mylonitic fabric in a Cretaceous granite in the footwall. This observation suggests an extensional, core complex–style deformation to produce this structure. We suggest that 3-D mapping has the potential to revolutionize geologic mapping studies, particularly where steep topography provides 3-D views that are virtually invisible on conventional 2-D maps. Previously bewildering geologic puzzles can be solved by the ability to visualize large cliff exposures from arbitrary angles and map the features in true 3-D at resolutions to the centimeter level. Although this study emphasized intermediate scales imaged by a drone, our methods here are easily extended to larger scales using a crewed aircraft for imaging. We suggest these methods should be used routinely in frontier areas with steep terrain where aviation is already in use for access, but the methods can be employed anywhere steep terrain “hides” major rock exposures on conventional 2-D maps.

Utilization of Micro Influencers and Engagement in Social Media to Gain Cadet Candidates

Since COVID-19 hit the world, Shipping Colleges and schools around the world have experienced severe disruption. One of the challenges that arises is how to attract people back to register themselves as seafarers as a career choice in the future. To solve this problem, Poltekpel Barombong conducts comprehensive activities by mobilizing public relations and utilizing social media platforms such as Instagram. This research is participatory with qualitative descriptive methods. The subjects used were 226 prospective cadets who were declared to have passed the selection for cadet candidates at the Poltekpel Barombong throughout 2022. The results showed that the use of social media is very good to be implemented in the future with various things that must be maximized: 1) there needs to be continuous cooperation with influencers; 2) development in the presentation of content in accordance with the times; 3) investment in much more up-to-date equipment with competent resources to operate it. The use of social media in socializing the selection of prospective cadets has various advantages such as relatively cheap costs, but there are also various disadvantages including not reaching underdeveloped, frontier and outermost areas.

Economy of production: A theory of household labor organization and material reuse

AbstractHousehold economic studies of preindustrial societies have overlooked one very specific and common material aspect: thrift. This article introduces a theory of economic production for household analysis that focuses on the economic use of materials, space, and labor. This framework is especially integral to understanding emergence of hierarchies. In emerging hierarchies, craft production at the household level can play a key part in the accumulation of power because the scale and type of craft production are moderated by the availability and abundance of material, space, and labor. Control of craft production can mean control of material, space, and labor, and thrifty control can increase production; this is key to emerging economies, particularly those located in a frontier area. Because women are often most associated with household labor, examining cultural definitions of thrift and waste provides a more complete understanding of household gender relations and reframes the importance of women's labor. Using an example from a 14th‐century Mississippian frontier site in Virginia, I show that women engaged in craft production and that by using materials, space, and labor economically, they increased their power over time. An economy of production theoretical perspective highlights a significant factor, thrift, in household organization and agency.
